Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, a threaded hole air-blowing fixture includes a support base 1, which is provided with a positioning structure for supporting the workpiece, and an air-blowing device is provided at the bottom of the support base 1. A through groove 11 is formed in the middle of the support base 1. The positioning structure includes a plurality of positioning seats 2 arranged around the periphery of the through groove 11. The positioning seats 2 are provided with upright positioning blocks 32 and locking blocks 24. The inner sidewall of the positioning blocks 32 is formed with an arc-shaped contact surface 28 that fits against the workpiece. An air-blowing column 21 is provided in the through groove 11. The air-blowing column 21 is formed with an air-blowing hole 22. A pneumatic connector 14 communicating with the air-blowing hole 22 is installed at the bottom of the air-blowing column 21.

[0021] When installing the workpiece, the locking block 24 of the positioning seat 2 cooperates with the groove structure of the workpiece to achieve locking, and the arc-shaped contact surface 28 of the positioning block 32 fits against the outer wall of the workpiece to achieve secondary positioning. This can achieve stable positioning of the workpiece, reduce the contact area between the fixture and the product, increase the material drop hole, and avoid damaging the product. After positioning, the air column 21 located in the through groove 11 is exactly aligned with the threaded hole of the workpiece. The pneumatic connector 14 blows the workpiece debris outward through the air hole 22 of the air column 21 to prevent the hole from being blocked. Since the through groove 11 is formed in the middle of the support seat 1, the residual waste in the threaded hole can be efficiently removed, ensuring smooth product assembly. This improves production efficiency and meets customer needs.

[0022] Specifically, the bottom of the air column 21 has a bottom mounting hole 23 for inserting the pneumatic connector 14. The diameter of the bottom mounting hole 23 is larger than the diameter of the air blowing hole 22. The pneumatic connector 14 includes a connector body 15 and a pneumatic output head 16 formed on the top of the connector body 15. The pneumatic output head 16 is connected to the bottom mounting hole 23. The pneumatic output head 16 on the top of the pneumatic connector 14 is inserted into the bottom mounting hole 23 for installation. A pneumatic input head 17 is installed on the side of the pneumatic connector 14. The pneumatic input head 17 is connected to a pneumatic pipeline. Gas enters the pneumatic connector 14 from the pneumatic input head 17 and is then introduced into the air column 21 through the pneumatic output head 16. The air blowing hole 22 of the air column 21 removes residual debris from the threaded holes of the workpiece, ensuring smooth product assembly, improving production efficiency, and meeting customer needs.

[0023] Furthermore, the pneumatic connector 14 is also provided with an air regulating valve 18, which is connected to the connector body 15. The air regulating valve 18 is an adjusting screw. When the adjusting screw rotates, the insertion depth can be adjusted, thereby adjusting the airflow speed and making the speed of pneumatic flow controllable.

[0024] Furthermore, a fixed base 12 is provided below the support base 1, and an upright support column 13 is installed on the fixed base 12. The top of the support column 13 is connected to the support base 1. There is a space between the fixed base 12 and the support base 1 for installing the pneumatic connector 14.

[0025] Furthermore, the positioning base 2 is provided with a first mounting structure 3 for mounting the positioning block 32 and a second mounting structure for mounting the locking block 24.

[0026] Specifically, the first mounting structure 3 includes a first sliding groove 31 formed along the radial direction of the positioning seat 2, and a first sliding block 33 formed at the bottom of the positioning block 32 that slides in cooperation with the first sliding groove 31; the positioning block 32 has a recessed first top hole 34, and the first sliding groove 31 has a plurality of equidistant first bottom holes formed along the length direction, the first bottom holes and the first top holes 34 cooperating with each other, wherein the first top hole 34 is provided with a locking pin 35 that is locked and connected to the first bottom hole.

[0027] Different shaped positioning blocks 32 and locking blocks 24 are manufactured according to different workpiece shapes for easy replacement. The positioning block 32 can be disassembled and replaced through the sliding engagement of the first sliding block 33 and the first sliding groove 31. When the shape of the workpiece changes, that is, when it is replaced with a workpiece of a different size or a workpiece with a slightly adjusted shape, the required positioning structure needs to be changed. In order to reduce costs, without the need to replace the fixture assembly, only the positioning block 32 of a different shape needs to be disassembled and replaced, which can be adapted to the corresponding workpiece. Disassembly is convenient. The first sliding block 33 and the first sliding groove 31 are both T-shaped, so they are not easy to fall off after installation, ensuring the stability of the installation and facilitating the support of the workpiece.

[0028] Furthermore, an arc-shaped plate 36 is installed on the inner wall of the positioning block 32, and an arc-shaped contact surface 28 is formed on the arc-shaped plate 36. A back rod 37 is installed on the back of the arc-shaped plate 36, and the positioning block 32 is formed with a guide hole coaxially aligned with the back rod 37. A compression spring 38 is sleeved on the back rod 37. When different workpieces are replaced, when the outer wall of the workpiece is contacted, the arc-shaped plate 36 can move radially through the sliding engagement of the back rod 37 and the guide hole, which can more accurately contact the workpiece and further improve the comprehensiveness of positioning, ensuring that the workpiece is contacted and positioned at multiple angles.

[0029] Furthermore, the second mounting structure includes a rotating shaft 25 mounted on the bottom of the clamping block 24. The bottom of the rotating shaft 25 is rotatably connected to the positioning seat 2. The positioning seat 2 is formed with a rotating hole that is rotatably connected to the rotating shaft 25, allowing the angle of the clamping block 24 to change. The rotating shaft 25 is dampedly rotatably connected to the rotating hole, ensuring that the angle can be maintained after rotating to different angles. When the shape of the workpiece changes, i.e., when it is replaced with a workpiece of a different size or a workpiece with a slightly adjusted shape, the required positioning structure needs to change. In order to reduce costs, without the need to replace the fixture assembly, it is only necessary to disassemble and replace it with a clamping block 24 of a different shape to adapt to the corresponding workpiece.

[0030] Preferably, the positioning seat 2 is formed with an installation groove 26, and a sliding mounting seat 27 is slidably mounted on the installation groove 26. A rotating hole is formed in the sliding mounting seat 27. The locking block 24 is connected to the sliding mounting seat 27 through a rotating shaft 25. Through the sliding mounting of the sliding mounting seat 27 and the installation groove 26, an interlocking connection can be achieved, which is convenient for disassembly and replacement.

[0031] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0032] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
