Description
Technical Field
[0001] The utility model relates to the technical field of parts processing auxiliary devices, in particular to a fixing device with a precise positioning function. Background Art
[0002] Currently, a fixing device with precise positioning function is usually called a positioning fixture or locator. The main task of the positioning fixture is to accurately position and fix the workpiece during the production process to ensure the processing accuracy and product quality of the workpiece.
[0003] Parts need to be fixed with fixtures for production and processing. In some processing plants with insufficient automation, some fixtures only have fixing functions but no positioning functions. The position where the part is fixed is the center point of processing. However, after a period of use, the fixed part will deviate from the center position of processing due to wear of the device. In this way, processing errors will occur in the processed parts, resulting in waste. The more complex the fixture, the more likely it is to deviate from the center. Therefore, it is necessary to design a fixture that can both fix and position the parts. Utility Model Content

[0006] Through the above technical solution, the rotation of the first bidirectional threaded rod will allow the sliding block to clamp and fix the part, and the part can be accurately positioned at the center of the processing by cooperating with the positioning component.

Both ends of the first bidirectional threaded rod are fixedly sleeved with a first bearing, and the first bidirectional threaded rod rotates with the base plate through the first bearing.

[0012] Through the above technical solution, the clamping plate can be disassembled and replaced adaptively according to the shape of the part.

[0015] As a further improvement of the above solution, the positioning plate is arranged in an "L" shape, a limiting plate is fixedly installed on one side of each of the positioning plates, and one side of each of the limiting plates extends into the interior of the adjacent moving groove.
[0016] Through the above technical solution, the limiting plate and the moving groove can cooperate to limit the movement of the positioning plate.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] By providing a clamping assembly and a positioning assembly, when processing a part, the clamping assembly can clamp and fix the part, and the positioning assembly will clamp and push the part to make the part located at the center position of the processing.

[0024] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.
[0025] Please refer to Figures 1 - 3 , A fixing device with a precise positioning function in this embodiment includes a bottom plate 1. Inside the bottom plate 1, there is a clamping assembly for fixing and clamping parts. On the clamping assembly, there is a positioning assembly for precisely positioning the clamped parts and pushing them to the center point. A sliding groove is opened on one side of the bottom plate 1. The clamping assembly includes a first bidirectional threaded rod 201 arranged inside the sliding groove and two sliding blocks 202 threadedly engaged with the first bidirectional threaded rod 201. Both ends of the first bidirectional threaded rod 201 penetrate through the bottom plate 1 and are fixedly installed with first rotating blocks 4. Both ends of the first bidirectional threaded rod 201 are fixedly sleeved with first bearings. The first bidirectional threaded rod 201 is rotationally matched with the bottom plate 1 through the first bearings. On one side of each sliding block 202, a clamping plate 5 is fixedly installed. Two symmetric moving grooves are opened on each clamping plate 5. When the first bidirectional threaded rod 201 rotates, the sliding blocks 202 will clamp and fix the parts. Cooperating with the positioning assembly, the parts can be accurately positioned to the center position of the processing.
[0026] Refer to Figures 1 - 3 , A threaded hole is opened on one side of each sliding block 202. A threaded column 6 is provided on one side of each clamping plate 5. One end of each threaded column 6 threadedly penetrates through the adjacent clamping plate 5 and extends into the adjacent threaded hole. The other end of each threaded column 6 is fixedly installed with a tightening block. By rotating the threaded column 6, the clamping plate 5 can be detached and replaced according to the shape of the parts.
[0027] Refer to Figures 1 - 3, the positioning assembly includes a second bidirectional threaded rod 301 rotatably arranged on each sliding block 202 and two positioning plates 302 threadedly sleeved on each second bidirectional threaded rod 301. A second bearing is fixedly sleeved on each second bidirectional threaded rod 301, and each second bidirectional threaded rod 301 is rotatably matched with the adjacent sliding block 202 through the second bearing. Limit plates 7 are fixedly installed at both ends of each clamping plate 5. A third bearing is fixedly sleeved on both ends of each second bidirectional threaded rod 301, and each second bidirectional threaded rod 301 is rotatably matched with the adjacent limit plate 7 through the third bearing. Second rotating blocks are fixedly installed at both ends of each second bidirectional threaded rod 301. The positioning plate 302 is arranged in an "L" shape. A limiting plate 8 is fixedly installed on one side of each positioning plate 302, and one side of each limiting plate 8 extends into the interior of the adjacent moving groove. When the second bidirectional threaded rod 301 rotates, the two positioning plates 302 will position and push the part.
[0028] The implementation principle of a fixing device with a precise positioning function in the embodiment of this application is as follows: Place the part on the bottom plate 1, rotate the first bidirectional threaded rod 201, and use the two sliding blocks 202 and the clamping plate 5 to push the part to a suitable position. Then rotate the second bidirectional threaded rod 301 to make the four positioning plates 302 push the part. In this way, the part will be pushed to the position of the processing center point. Subsequently, tighten the first bidirectional threaded rod 201 and the second bidirectional threaded rod 301 to realize the positioning and clamping of the part, so that the part is in the center position of the processing. And when the shape of the part is different, the threaded post 6 can also be screwed off, so that the clamping plate 5 and the positioning plate 302 can be replaced, which is convenient for clamping different parts. Such a setting can not only position and clamp the part, but also replace the positioning assembly according to the needs of the part, so as to make the positioning and clamping more accurate.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
