[0023] Please refer to Figs. 1-3 A quick fastening tool for bolt production, comprising a bottom plate 1, the upper end surface of the bottom plate 1 is fixedly connected with a workbench 2; the upper end surface of the workbench 2 is provided with a clamping mechanism;

[0024] The clamping mechanism comprises two fixed plates 202 fixedly connected to the end face of the workbench 2 and symmetrically distributed, two bases 3 arranged on the workbench 2, two V-shaped clamping blocks 4 arranged on the end face of the two bases 3 and oppositely arranged, a cylinder 203 arranged on the side opposite to the two fixed plates 202 and having an output end fixedly connected to the two bases 3, and the base 3 and the clamping block 4 are connected through a positioning mechanism;

[0025] The positioning mechanism comprises a mounting groove 301 arranged in the base 3, a mounting block 304 fixedly connected to the bottom end of the clamping block 4 and matched with the mounting groove 301, two positioning grooves 302 arranged in the outer wall of the mounting block 304, two positioning columns 401 slidably connected in the base 3 and matched with the positioning grooves 302, two first electromagnets 303 arranged between the positioning column 401 and the positioning groove 302 and capable of being attracted to each other, a fixed disc 402 fixedly connected to the end opposite to the two positioning columns 401, a spring 404 sleeved on the outer wall of the positioning column 401 and arranged between the fixed disc 402 and the base 3, and a second electromagnet 403 arranged between the outer wall of the base 3 and the fixed disc 402 and capable of being attracted to each other.

[0026] In this embodiment, the bolt to be processed is placed between the two clamping blocks 4, and the controller is used to control the two cylinders 203 (connected to an external air pump) to operate synchronously, so that the two cylinders 203 synchronously push the two bases 3 to move close to each other, so that the two bases 3 drive the two clamping blocks 4 to move relative to each other, until the two clamping blocks 4 clamp and fix the bolt, and then the automatic clamping can achieve the effect of fast clamping, and the subsequent processing efficiency is improved.

[0027] When different types of bolts need to be processed, the controller can be used to control the first electromagnet 303 and the second electromagnet 403 to be de-energized, so as to cut off the current of the first electromagnet 303 and the second electromagnet 403 and demagnetize them. At the same time, the positioning column 401 moves away from the positioning groove 302 under the elastic force of the spring 404, so that the positioning column 401 drives the part of the first electromagnet 303 connected thereto to move away from the positioning groove 302 (and because the height of the first electromagnet 303 is greater than the diameter of the sliding hole, the positioning column 401 can avoid moving away from the base 3), and then the clamping block 4 is pulled up, so that the mounting block 304 is separated from the mounting groove 301. The mounting block 304 on the clamping block 4 of another type is placed in the mounting groove 301, and then the second electromagnet 403 and the first electromagnet 303 are energized to generate magnetic attraction force, so as to pull the fixed disc 402 to the side wall of the base 3, so as to make the positioning column 401 enter the positioning groove 302, so as to make the two first electromagnets 303 attract each other, and the two second electromagnets 403 attract each other, so as to realize the locking of the clamping block 4. Therefore, the clamping block 4 can be quickly replaced according to the actual processing condition, and the multi-specification adaptation capability and the stability of clamping are improved.

[0028] As a technical optimization scheme of the utility model, the positioning mechanism further comprises two sliding holes penetratingly provided on the outer wall of the base 3 and slidably connected with the positioning column 401.

[0029] In the embodiment, the positioning column 401 is stably slid through the sliding hole.

[0032] As a technical optimization scheme of the utility model, the upper end face of the workbench 2 is provided with two sliding grooves 201 slidably connected with the two bases 3, respectively.

[0033] In the embodiment, the base 3 is stably moved on the workbench 2 through the sliding groove 201.

[0034] As a technical optimization scheme of the utility model, the front end face of the workbench 2 is inserted with the storage box 5.

[0035] In the embodiment, the storage box 5 is used to place the clamping blocks 4 for clamping different types of bolts.

[0036] As a technical optimization scheme of the utility model, the outer wall of the workbench 2 is provided with a controller, and the first electromagnet 303, the second electromagnet 403 and the air cylinder 203 are all controlled by the controller.

[0037] In the embodiment, the first electromagnet 303 and the second electromagnet 403 are controlled to normally work through the controller, and the two air cylinders 203 are controlled to synchronously work through the controller, and the model of the controller is PLC (such as Siemens S7-1200) or a special motion controller (such as Gotion GTN), which both have multi-axis synchronous control and multi-path I / O control capabilities.

[0038] The working principle and use process of the utility model are as follows: the bolt to be processed is placed between the two clamping blocks 4, and the two air cylinders 203 (connected with an external air pump) are synchronously operated through the controller to synchronously push the two bases 3 to move close to each other, so that the two bases 3 drive the two clamping blocks 4 to relatively move in the sliding groove 201 until the two clamping blocks 4 clamp and fix the bolt, and then the automatic clamping can realize the fast clamping effect and improve the subsequent processing efficiency.

[0039] When different types of bolts need to be processed, the controller can control the first electromagnet 303 and the second electromagnet 403 to be powered off, thereby cutting off the current of the first electromagnet 303 and the second electromagnet 403 to demagnetize, and at the same time, the positioning column 401 moves away from the positioning groove 302 under the elastic force of the spring 404, so that the positioning column 401 drives the part of the first electromagnet 303 connected thereto to be separated from the positioning groove 302 (and because the height of the first electromagnet 303 is greater than the diameter of the sliding hole, the positioning column 401 can be prevented from being separated from the base 3), then the clamping block 4 is pulled up, the mounting block 304 is separated from the mounting groove 301, the mounting block 304 on another type of clamping block 4 is clamped and placed in the mounting groove 301, then the second electromagnet 403 and the first electromagnet 303 are powered on to generate magnetic attraction force, the fixed disc 402 is pulled to the side wall of the base 3, the positioning column 401 is promoted to enter the positioning groove 302, two first electromagnets 303 are attracted, and two second electromagnets 403 are attracted, so that the clamping block 4 is locked, and then the clamping block 4 can be quickly replaced according to the actual processing condition, and the multi-specification adaptation capability and the clamping stability are improved.
