Technical Field
[0001] The utility model relates to the technical field of linear guide production equipment, in particular to a fixture for linear guide production. Background Art
[0002] A linear guide is used to support and guide moving parts to perform reciprocating linear motion in a given direction. According to the friction property, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc. During the processing and production of linear guides, fixtures are required to fix them.
[0003] When the existing fixtures for linear guide production fix linear guides of different specifications, different specifications of fixing fixtures need to be replaced. At the same time, after the fixture clamps and fixes the linear guide, it cannot move the linear guide. Since the length of the linear guide is generally long, when performing fine processing on its surface, operators still need to move to different positions of the linear guide for operation, which is inconvenient to use. Summary of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model provides a fixture for linear guide production to solve the problems raised in the above background art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A placement plate is fixedly arranged at the top of the sandwich plate. A support shaft is rotatably arranged inside the sandwich plate. A sprocket is fixedly arranged on the surface of the support shaft. A chain is meshed on the surface of the sprocket. The chain is meshed and connected with another sprocket. A connecting plate is fixedly arranged on the surface of the chain. A moving plate is fixedly arranged on the side of the connecting plate close to the center of the placement plate. A buffer assembly is arranged inside the moving plate. A clamping plate is arranged on the moving plate through the buffer assembly. A driving assembly is arranged on the front side of the support plate.
[0007] Preferably, the buffer assembly includes a limit shaft movably arranged inside the moving plate. An elastic member is arranged on the surface of the limit shaft. One end of the limit shaft close to the center of the placement plate is fixedly connected with the clamping plate.

[0012] Preferably, the number of the driving motors is two, and the two driving motors are symmetrically distributed inside the bracket.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the fixture for manufacturing linear guide rails, place the linear guide rail on the placing plate, start the two driving motors. The two driving motors respectively drive the supporting shafts on both sides to rotate in different directions.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Referring to Figures 1-4 , a fixture for producing linear guides includes a support plate 1. Two sandwich plates 2 are fixedly arranged on the top of the support plate 1. A placement plate 3 is fixedly arranged on the top of the sandwich plates 2. A support shaft 6 is rotatably arranged inside the sandwich plate 2. A sprocket 7 is fixedly arranged on the surface of the support shaft 6. A chain 8 is meshed on the surface of the sprocket 7. The chain 8 is meshed and connected with another sprocket 7. A connecting plate 9 is fixedly arranged on the surface of the chain 8. A moving plate 10 is fixedly arranged on the side of the connecting plate 9 close to the center of the placement plate 3. A buffer assembly is arranged inside the moving plate 10. A clamping plate 13 is arranged on the moving plate 10 through the buffer assembly. A driving assembly is arranged on the front side of the support plate 1. The driving assembly includes a bracket 4 fixedly arranged on the front side of the support plate 1. A driving motor 5 is fixedly arranged inside the bracket 4. The output end of the driving motor 5 is fixedly connected with the support shaft 6. The number of the driving motors 5 is two, and the two driving motors 5 are symmetrically distributed inside the bracket 4. The two driving motors 5 can make the clamping plates 13 on both sides move in the same direction or in opposite directions. A chassis 14 is fixedly arranged at the bottom of the support plate 1. The number of the chassis 14 is multiple. For this fixture for producing linear guides, place the linear guide on the placement plate 3, start the two driving motors 5. The two driving motors 5 respectively drive the support shafts 6 on both sides to rotate in different directions. The rotation of the support shaft 6 drives the rotation of the sprocket 7. The rotation of the sprocket 7 drives the rotation of the chain 8 on its surface. The rotation of the left chain 8 drives the left connecting plate 9 to move to the right. The rotation of the right chain 8 drives the right connecting plate 9 to move to the left. The opposite movement of the connecting plates 9 on both sides makes the moving plates 10 on both sides move, and further makes the clamping plates 13 on both sides approach each other to fix the linear guide. When it needs to be moved after fixation, both driving motors 5 drive the support shaft 6 to rotate in the same direction, so that the two clamping plates 13 both move in the same direction, then push the linear guide to move. This device can clamp and fix linear guides of different lengths, and at the same time can horizontally move the position of the linear guide after it is fixed, improving the practicability of the device.
[0021] Specifically, the buffer assembly includes a limiting shaft 11 movably arranged inside the moving plate 10. An elastic member 12 is arranged on the surface of the limiting shaft 11. One end of the limiting shaft 11 close to the center of the placing plate 3 is fixedly connected to the clamping plate 13. The elastic member 12 is a spring. One end of the elastic member 12 is fixedly connected to the moving plate 10, and the other end of the elastic member 12 is fixedly connected to the clamping plate 13. The number of the elastic members 12 is multiple, and the multiple elastic members 12 are linearly distributed on the surface of the moving plate 10. When the end of the clamping plate 13 close to the linear guide rail continues to move after approaching it, the clamping plate 13 will push the limiting shaft 11 to slide inside the moving plate 10. At the same time, the clamping plate 13 will compress the elastic member 12. The elastic rebound of the elastic member 12 reduces the force on the end of the linear guide rail, thereby preventing the clamping end of the linear guide rail from being worn due to excessive force.
[0022] The electrical components mentioned in this article are all electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.
[0023] During use: Place the linear guide rail on the placing plate 3, and start the two driving motors 5. The two driving motors 5 respectively drive the support shafts 6 on both sides to rotate in different directions. The rotation of the support shafts 6 drives the sprockets 7 to rotate. The rotation of the sprockets 7 drives the chains 8 on their surfaces to rotate. The rotation of the left chain 8 drives the left connecting plate 9 to move to the right, and the rotation of the right chain 8 drives the right connecting plate 9 to move to the left. The opposite movement of the two connecting plates 9 makes the moving plates 10 on both sides move, and further makes the clamping plates 13 on both sides approach each other. When the end of the clamping plate 13 close to the linear guide rail continues to move after approaching it, the clamping plate 13 will push the limiting shaft 11 to slide inside the moving plate 10. At the same time, the clamping plate 13 will compress the elastic member 12. The elastic rebound of the elastic member 12 reduces the force on the end of the linear guide rail. When the two clamping plates 13 clamp and fix the linear guide rail and need to move to the left, the left driving motor 5 drives the left support shaft 6 to rotate, and the right driving motor 5 drives the right support shaft 6 to rotate in the same direction. Through the sprockets 7 and the chains 8, the two connecting plates 9 both move to the left. The leftward movement of the connecting plate 9 drives the clamping plate 13 to move to the left through the moving plate 10 and the limiting shaft 11, thus pushing the linear guide rail to move to the left. When it is necessary to move to the right, that is, the two driving motors 5 both drive the support shafts 6 to rotate in the reverse direction.
[0024] In summary, for the fixture for manufacturing linear guide rails, place the linear guide rail on the object placing plate 3, start the two driving motors 5. The two driving motors 5 respectively drive the support shafts 6 on both sides to rotate in different directions. The rotation of the support shafts 6 drives the sprockets 7 to rotate. The rotation of the sprockets 7 drives the chains 8 on their surfaces to rotate. The rotation of the left chain 8 drives the left connecting plate 9 to move to the right, and the rotation of the right chain 8 drives the right connecting plate 9 to move to the left. The opposite movement of the connecting plates 9 on both sides causes the moving plates 10 on both sides to move, and further causes the clamping plates 13 on both sides to approach each other to fix the linear guide rail. When it is necessary to move after fixation, both driving motors 5 drive the support shafts 6 to rotate in the same direction, so that both clamping plates 13 move in the same direction, thereby pushing the linear guide rail to move. This device can clamp and fix linear guide rails of different lengths, and at the same time can horizontally move the position of the linear guide rail after it is fixed, improving the practicability of the device.
