Embodiment 1

[0042] In this example, if image 3 As shown, in order to reduce the input torque when the output torque is the same, so as to achieve labor-saving effect, reduce the input of power, and change the rotation direction of the output torque to make it the same as the rotation direction of the input torque, the present invention Several transition gears 8 are also provided. Specifically, a gear shaft 83 is fixedly installed on the base 1, and the transition gear 8 is sleeved on the gear shaft 83 and can rotate relative to the gear shaft 83. Two layers of gears 82 , the first layer of gears 81 and the second layer of gears 82 are vertically arranged up and down, the first layer of gears 81 is used for meshing with the driving gear 4 , and the second layer of gears 82 is used for meshing with the driven gear 2 . At this time, the driving gear 4 is no longer installed on the upper surface of the base 1, but has a distance from the base 1, and passes through a positioning structure, ...

Embodiment 2

[0059] The structural difference between this embodiment and Embodiment 1 lies in that: in order to avoid deformation of the fastened part due to excessive applied torque, the present invention also includes a protection structure for the fastened part, and a protective structure for protecting the fastened part. The protective structure of the fastener, when the torque applied to the driving gear 4 is less than or equal to the standard torque of the fastener, through the protection structure, the driving gear 4 rotates under the action of a single power source to realize the tightening The fastening effect of the firmware, when the torque applied to the driving gear 4 is greater than the standard torque required by the fastener, through the protection structure, the driving gear 4 is separated from the action of a single power source and stops rotating, no longer The fastening action exerted by the fastener.

[0060] Further preferably, in order to better realize the protecti...

Embodiment 3

[0067] The difference in structure between this embodiment and embodiment 1 and embodiment 2 is: the axes of driving gear 4 and transition gear 8, transition gear 8 and driven gear 2 are parallel to each other and staggered in the axial direction, when the driving gear When 4 moves toward the transition gear 8 and the driven gear 2, one of the cases is that the gap between the teeth of the driving gear 4 coincides with the teeth of the transition gear 8, and the gap between the teeth of the transition gear 8 coincides with the tooth gap of the driven gear 2. When the teeth coincide, the driving gear 4, the transition gear 8 and the driven gear 2 can enter normal meshing without any rotation; in another case, the teeth of the driving gear 4 and the transition gear 8 and the transition gear 8 and the driven gear 2 When the center line overlaps in the mathematical sense, neither the driving gear 4 and the transition gear 8, nor the transition gear 8 and the driven gear 2 can engag...

Abstract

The invention relates to an automatic device for being capable of fastening multiple screws at the same time, in particular to a synchronous fastening device. The synchronous fastening device achievesthe purpose of being simple in structure, convenient to adjust, high in reliability and uniform in stress of a fastened piece. The synchronous fastening device comprises a power source, a base, a fixing shaft fixedly installed at one side of the base, a driving gear which sleeves the fixing shaft and can rotate relative to the fixing shaft, a plurality of driven gears capable of being externallymeshed with the driving gear, a plurality of transmission shafts capable of synchronously rotating relative to the driven gears, and a fastening piece which is connected with one ends of the transmission shafts and can synchronously move along with the transmission shafts. The fastening piece is used for fastening the piece to be fastened. The fastening piece is matched with the piece to be fastened. The power source is used for supplying power to the driving gear. The automatic device further comprises a transition gear. The device adopts the single power source to achieve synchronous screwing of the screws, assembling and adjusting are easy, the cost is low, the requirement for the environment is low, and the application range is wide.

Description

technical field [0001] The invention relates to the field of design and manufacture of transmission equipment, in particular to an automatic device capable of fastening multiple screws at the same time. Background technique [0002] With the advancement of science and technology, various industries are changing from manual operations to mechanized and automated production methods. [0003] Through investigation, it is found that the current method and sequence of tightening screws are basically manually screwed in one by one, and then each screw is recirculated and gradually tightened, but this manual tightening method will result in effective tightening of each screw The force is different, and when the screws are manually tightened, the control of the tightening force depends on experience and feeling. When the tightening force is too large, it is easy to cause deformation and failure of the fasteners, especially in pressure tanks and Where multiple screws are used to fas...
