The invention provides a stable high-precision workpiece fixing tool for a stamping die, relates to the technical field of workpiece fixing, and solves the problem that parts cannot be automatically clamped in the stamping process through structural improvement, and cleaning of residues cannot be achieved through linkage in the stamping process through structural improvement are solved. The stable high-precision workpiece fixing tool for the stamping die comprises a base. Two clamp structures are mounted on the base. The poke rod C is welded on the bottom end surface of a clamp plate, and the poke rod C is aligned with the top end surface of a stress seat B. The top end surface of the stress seat B is of an inclined structure, the poke rod C forms an extrusion poke structure of the stress seat B, and therefore when the poke rod C moves along with the clamp plate to achieve part clamping, hiding of a positioning base can be synchronously achieved, and then the cleaning effect is improved.

The invention relates to friction stir spot welding (FSSW) equipment with an automatic clamping device. The FSSW equipment comprises an upper computer, a ring-shaped upper clamping plate, a lower clamping plate arranged corresponding to the upper clamping plate and a driving mechanism used for driving the upper clamping plate to move up and down. The driving mechanism is fixedly connected with the FSSW equipment. A stir head of the FSSW equipment penetrates the upper clamping plate and is perpendicular to a weld joint. The upper computer starts the driving mechanism; the upper clamping plate moves downwards to be matched with the lower clamping plate to clamp a workpiece to be welded; the stir head is started; when welding is completed, the stir head begins to Retreat; and simultaneously the upper clamping plate is controlled by the driving mechanism to move upwards, and the workpiece is unclamped. According to the FSSW equipment, the upper clamping plate is matched with the lower clamping plate, so that the workpiece clamping action is achieved, and the phenomenon of the flexure on the periphery of a welding spot of the workpiece in the welding process of the workpiece is avoided.

The invention relates to industrial automation device, in particular to an automation manipulator. The compound forging manipulator comprises a gripper and a finger. The gripper comprises a finger body, a guide rail, pistons, a plunger pin and sliders. The finger is fixedly connected to the sliders and comprises a finger tip and a bridge, one end of the bridge is fixedly connected to the sliders while the other end of the same is fixedly connected with the finger, and a clamping face is arranged on the finger. When a workpiece is impacted or bumped, affections of impact on the gripper can be avoided or reduced due to an elastic function of the finger. Graphite can be sprayed to a die while the workpiece is gripped simultaneously, so that production efficiency is improved; liquid fed into an inlet flows out of an outlet via a channel, heat accumulated through the fingers is taken away by the flowing liquid, temperature of the fingers can be greatly reduced, and the finger can be kept at constant temperature under working conditions; meanwhile, the high-temperature workpiece is subjected to quenching treatment.

The invention belongs to the technical field of load hanging elements or devices, and particularly discloses a lifting appliance for crane maintenance. The lifting appliance comprises a clamping mechanism, a lifting mechanism, a prying mechanism and a driving mechanism. According to the lifting appliance, to-be-lifted parts can be pried through the prying mechanism, thus the pried to-be-lifted parts can be easily clamped and positioned by the clamping mechanism and moved to the target position through the lifting mechanism, and the clamping mechanism and the prying mechanism are both driven bythe driving mechanism. The problem that in the prior art, a lifting appliance directly makes contact with the ground, and thus the lifting appliance is seriously abraded is solved.

The invention provides a live lead clip which includes a main body, a wire clamping slider, a first nut, a second nut, and a driving bolt. The main body is composed of a wire clamping part which is used for clamping a wire and wedge-shaped in the whole when used, and a drainage wire connecting part which is arranged on the lower side of the wire clamping part, integrally connected with the wire clamping part and connected with a drainage wire when in use, wherein the wire clamping part and the drainage wire connecting part are integrated. The wire clamping slider is a structural member which is in sliding fit with the wire clamping part of the main body and wedge-shaped in the whole. The first nut is fixed on the wire clamping slider. The second nut is fixed on the wire clamping part of the main body. The driving bolt is screwed with the first nut and the second nut. When the live lead clip is used, the driving bolt is screwed by an arranging tool, and the wire clamping slider can slide in the wire clamping part of the main body to clamp the wire of a power transmission line. The lead clip provided by the invention has the advantages of simple structure, low cost, convenient installation and operation during use, has the advantages of the existing similar devices, and overcomes the disadvantages of the existing similar devices.

The invention discloses an auxiliary material-loading device for a vertical continuous plating line. The auxiliary material-loading device comprises a support and a lifting tray, wherein the lifting tray is capable of moving up and down and located on the support, and when the upper end of a to-be-processed workpiece is arranged in the clamp of the vertical continuous plating line and the lower end of the to-be-processed workpiece is arranged on the lifting tray, the to-be-processed workpiece can move with the clamp of the vertical continuous plating line. According to the device, the disadvantages of high working labour intensity, cumbersome operation, low production efficiency and the like brought by manually supporting to load materials are effectively solved, and the manpower resource is greatly saved.

The invention discloses a coiler jaw. The coiler jaw comprises sector blocks, a four-edge mandril, a jaw sector block, a movable jaw and a fixed jaw, wherein the jaw sector block and the sector blocks are pieced together to form a cylinder; the four-edge mandril is arranged in the center of the cylinder; the movable jaw and the fixed jaw are arranged in the jaw sector block; the four-edge mandrilis driven by a driving mechanism to axially move along the center of the cylinder; and a wedge mechanism which converts axial movement of the four-edge mandril to radial movement of the movable jaw is arranged between the four-edge mandril and the movable jaw. The coiler jaw has the following beneficial effects: as the jaw horizontal movement wedge which can drive the jaw to horizontally move is adopted and is connected with the four-edge mandril as a whole, the pyramid coiler realizes expansion and shrinkage of the coiling block and clamping and loosening of the jaw by only using an expanding and shrinking cylinder used for pushing the four-edge mandril, thus greatly reducing the complexity of the coiling block and ensuring the coiling block to act sensitively and accurately.
