The moving devices are fixedly installed at the four corners, the right side of the inner wall of the equipment body is fixedly connected with the guide rail, the inner top wall of the equipment body is fixedly connected with the first motor through the fixed block, and the output shaft of the first motor is fixedly connected with the transmission shaft There is a first bevel gear, and the right side of the first bevel gear meshes with a second bevel gear. The inner ring of the second bevel gear is fixedly sleeved with a threaded rod. The top wall and the inner bottom wall are flexibly connected. The invention solves the problems of low working efficiency of the existing glass grinding machine, the vibration during grinding affects the quality of the grinding, and the problems of inconvenient transportation, and achieves the effects of high processing efficiency, good processing quality and convenient operation.

The invention discloses panel positioning components of a trailer frame assembly splicing welding system. The number of the panel positioning components is multiple, and the multiple panel positioning components are arranged on the upper surface of a workpiece supporting plate (31), and the panel positioning components comprise compression devices (32) and positioning devices (33); each compression device comprises a supporting base fixedly installed on the workpiece supporting plate, a stretchable control mechanism installed on the supporting base and a pressing head installed on the stretchable control mechanism, the compression directions of each compression device at least comprise the horizontal direction and the vertical direction, the compression devices are symmetrically arranged with respect to a positioned panel, and the pressing heads are oppositely arranged; and each positioning device comprises a large beam positioning mechanism, a transverse beam positioning mechanism and an edge beam positioning mechanism. By means of the panel positioning components of the trailer frame assembly splicing welding system, overall and quick splicing and welding of a trailer can be achieved, and the splicing and welding efficiency is high.

The invention relates to an environment-friendly building exterior wall decorative plate and its installation method, comprising a fixing frame, a positioning device and a plate body, the fixing frame is installed on the keel frame through screws, the fixing frame has an L-shaped structure, and the upper end of the fixing frame A reinforcing plate is installed between the keel frame, and the number of fixing frames is two. A positioning device is installed on the fixing frames, and a plate body is installed between the right ends of the positioning frames. The present invention can solve the problem of poor installation effect, inconvenient installation and disassembly of the existing exterior wall decoration boards, large gaps between the installed boards, and rainwater easily seeping into the boards, affecting the subsequent use of the boards In addition, when the existing decorative panels for exterior walls are used, the use effect of the panels is poor, the protective performance is low, the decorative layer of the panels is prone to breakage, and the broken panels are prone to fall off, which affects the safety of use and other problems.

The invention relates to the field of bimetallic saw strip machining, in particular to welding equipment and welding method for bimetallic band saw strips. The welding equipment comprises a laser generator, a base material supplying slide rail, a pre-welding position alignment device, a main controller, an upper fixture device and a lower fixture device, wherein the upper fixture device and the lower fixture device are symmetrically arranged up and down, the laser generator is arranged at the downstream end of the base material supplying slide rail, the upper fixture device and the lower fixture device are located above and below the base material supplying slide rail correspondingly, the back side of the base material supplying slide rail is provided with a power device, the front side and the back side of the base material supplying slide rail are each provided with one clamping device, and the pre-welding position alignment device can be movably arranged at the end portion of the downstream end of the base material supplying slide rail through an avoidance air cylinder and is further in electrical connection with the main controller. By means of the welding equipment and weldingmethod for the bimetallic band saw strips, two pre-welding base materials can be effectively clamped and positioned, and then the welding quality is improved, in addition, a rubber shaft sleeve and arubber sleeve which are in direct contact with the base materials can both be detachably arranged, and the fixture maintenance cost is greatly lowered.

The invention provides an upper cover plastic shell press-fitting device for assembling drivers. The upper cover plastic shell press-fitting device comprises a press-fitting working platform. A locating datum mechanism and a pressing mechanism are arranged on the working platform. The locating datum mechanism comprises a side pressing locating assembly and an end pressing locating assembly which do not interfere with each other. The side pressing locating assembly comprises a side pressing cylinder, a first side pressing plate and a second side pressing plate. The side pressing cylinder drivesthe first side pressing plate and the second side pressing plate to get close to each other or away from each other so as to clamp the side face of a semifinished driver. The end pressing locating assembly comprises an end pressing cylinder and an end pressing plate. The end pressing cylinder at least drives the end pressing plate to locate and press one end face of the semifinished driver. The pressing mechanism comprises a pressing cylinder and a press-fitting tool. A rod body of the pressing cylinder is connected with and drives the press-fitting tool to rise and drop relative to the press-fitting working platform to conduct press-fitting on an upper cover plastic shell and the semifinished driver. The upper cover plastic shell press-fitting device can guarantee accurate and efficientpress-fitting assembly of the upper cover plastic shell and the semifinished driver and is reliable in performance and capable of reducing the labor intensity of workers and lowering the labor cost.
