Description

Technical Field

[0001] This utility model relates to the field of fixture error prevention technology, specifically a tooling fixture error prevention device. Background Technology

[0002] During tooling processing, it is often necessary to first clamp and fix the tooling to ensure that it will not shift during subsequent processing. However, some tooling is symmetrical or it is not easy to distinguish the front and back. As a result, when the staff places the tooling, it is easy to place it backwards, which will lead to subsequent processing failure.

[0003] Therefore, a groove is pre-reserved on these error-prone toolings. Then, during processing, this groove is matched with the error-proofing mechanism to ensure the normal processing of the tooling. However, traditional error-proofing mechanisms are not easy to adjust. Often, one tooling corresponds to one error-proofing device, which cannot be adapted to different toolings.

[0004] To address this, a tooling fixture error prevention device is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a tooling fixture error prevention device to solve the problems mentioned in the background art.

[0007] A second extension plate is slidably connected to one end of the first extension plate. A second fixing bolt for fixing the position of the second extension plate is installed on the second extension plate, and an anti-misalignment rod is inserted into one end of the second extension plate.

[0008] Preferably, the first extension plate has a first groove, and the inside of the first groove is provided with a first threaded cylinder, which is installed on the upper surface of the U-shaped plate.

[0009] Preferably, the upper surface of the first extension plate is provided with a first pressure plate, and the first fixing bolt passes through the first pressure plate and is threadedly connected to the first threaded cylinder.

[0010] Preferably, the second extension plate has a second groove, and the interior of the second groove has a second threaded cylinder, which is installed at one end of the first extension plate.

[0011] Preferably, the upper surface of the second extension plate is provided with a second pressure plate, and the second fixing bolt passes through the second pressure plate and is threadedly connected to the second threaded cylinder.

[0012] Preferably, a snap-fit ​​hole is provided on one side of the second extension plate, the anti-misalignment rod is inserted into the snap-fit ​​hole, and a limit plate is installed on the outer side of the anti-misalignment rod.

[0013] Preferably, the lower surface of the U-shaped plate is threaded with a threaded rod, the bottom end of the threaded rod is fitted with a handle, and the top end of the threaded rod is fitted with a top plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by cooperating with the U-shaped plate and the threaded rod, the device is fixed on one side of the fixture, and then the positions of the first extension plate and the second extension plate are adjusted so that the anti-misalignment rod is adapted to the groove on the tooling, and the positions of the first extension plate and the second extension plate are fixed by bolts, so that in subsequent work, the anti-misalignment rod can be used to avoid the tooling being placed in reverse.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] Please see Figure 1-2 The present invention provides a technical solution: a tooling fixture error prevention device, including a U-shaped plate 1, a first extension plate 5 slidably connected on the U-shaped plate 1, and a first fixing bolt 8 for fixing the position of the first extension plate 5 installed on the first extension plate 5;

[0021] A second extension plate 9 is slidably connected to one end of the first extension plate 5. A second fixing bolt 12 for fixing the position of the second extension plate 9 is installed on the second extension plate 9. An anti-misalignment rod 13 is inserted into one end of the second extension plate 9.

[0022] like Figure 1 and Figure 2As shown: A first groove 6 is provided on the first extension plate 5, and a first threaded cylinder 14 is provided inside the first groove 6. The first threaded cylinder 14 is installed on the upper surface of the U-shaped plate 1. A first pressure plate 7 is provided on the upper surface of the first extension plate 5. A first fixing bolt 8 passes through the first pressure plate 7 and is threadedly connected to the first threaded cylinder 14. With the above arrangement, the first extension plate 5 can move outside the first threaded cylinder 14. When the position is appropriate, the position of the first extension plate 5 can be fixed by the cooperation of the first fixing bolt 8 and the first pressure plate 7.

[0023] like Figure 1 and Figure 2 As shown: A second sliding groove 10 is provided on the second extension plate 9, and a second threaded cylinder 15 is provided inside the second sliding groove 10. The second threaded cylinder 15 is installed at one end of the first extension plate 5. A second pressure plate 11 is provided on the upper surface of the second extension plate 9. A second fixing bolt 12 passes through the second pressure plate 11 and is threadedly connected to the second threaded cylinder 15. With the above arrangement, the second extension plate 9 can move left and right on the outside of the second threaded cylinder 15. Then, when the position of the second extension plate 9 is appropriate, the position of the second extension plate 9 can be fixed by the cooperation of the second pressure plate 11 and the second fixing bolt 12, thereby restricting and fixing the position of the anti-misalignment rod 13.

[0024] like Figure 1 and Figure 2 As shown: A snap-fit ​​hole 16 is provided on one side of the second extension plate 9, and the anti-misalignment rod 13 is inserted into the snap-fit ​​hole 16. A limit plate 17 is installed on the outside of the anti-misalignment rod 13. With the above settings, the inserted anti-misalignment rod 13 can be replaced more conveniently and quickly.

[0025] like Figure 1 and Figure 2 As shown: A threaded rod 2 is threadedly connected to the lower surface of the U-shaped plate 1. A handle 3 is installed at the bottom end of the threaded rod 2, and a top plate 4 is installed at the top end of the threaded rod 2. With the above settings, rotating the threaded rod 2 can adjust the position of the top plate 4, so that the device can be fixed in a certain place more conveniently and quickly.

[0026] Working principle: First, the handle 3 drives the threaded rod 2 and the top plate 4 to rotate, fixing the device next to the tooling fixture. Then, after adjusting the position of the tooling, it is placed on the fixture. Next, the first extension plate 5 and the second extension plate 9 are moved so that the anti-error rod 13 can be aligned with the anti-error groove on the tooling. Then, the positions of the first extension plate 5 and the second extension plate 9 are fixed by the first fixing bolt 8 and the second fixing bolt 12, so that after one tooling is processed, the next tooling can be placed more conveniently and quickly.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
