[0031] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 is a schematic diagram of the processing procedure of the workpiece to be processed, Figure 4 is Figure 5The tapping fixture in this example is used to fix the workpiece 100 to be processed to realize the drilling, tapping and other processes of the workpiece 100 to be processed. The tapping fixture includes a fixture body 1 and a limiting structure 2. The fixture body 1 is used to support the workpiece 100 to be processed, and the limiting structure 2 is used to limit the fixture body 1.
[0032] Among them, the clamp body 1 has a first mounting hole 11 and a mounting groove 12, and the mounting groove 12 is connected to the first mounting hole 11; the limiting structure 2 includes an elastic part 21, a limiting pin 22 and a limiting column 23, the elastic part 21 and the limiting pin 22 are both arranged in the mounting groove 12, one end of the elastic part 21 abuts against the clamp body 1, and the other end abuts against the limiting pin 22, the limiting pin 22 has a slide groove 221, the opening direction of the slide groove 221 is parallel to the setting direction of the elastic part 21, the limiting column 23 is fixed in the slide groove 221, and is fixedly connected to the clamp body 1, and the limiting pin 22 is slidably connected to the limiting column 23; the end of the limiting pin 22 facing away from the elastic part 21 extends into the first mounting hole 11.
[0033] Specifically, the first mounting hole 11 is inclined along the height direction of the clamp body 1, and the mounting groove 12 is arranged along the diameter direction of the clamp body 1. The mounting groove 12 opens at one end of the first mounting hole 11 and is connected to the first mounting hole 11; the elastic member 21, the limit pin 22 and the limit column 23 are all installed in the mounting groove 12, the elastic member 21 is located at the bottom of the mounting groove 12, the limit pin 22 is slidably connected to the mounting groove 12, one end of the limit pin 22 abuts against the elastic member 21, the limit pin 22 is provided with a sliding groove 221, the opening direction of the sliding groove 221 is parallel to the opening direction of the mounting groove 12, the elastic member 21 is parallel to the opening direction of the mounting groove 12, the limit column 23 is fixedly connected to the side wall of the mounting groove 12, and the limit column 23 is located in the sliding groove 221, and the limit pin 22 is facing away from one end of the elastic member 21, that is, the end of the limit pin 22 facing away from the bottom of the mounting groove 12 extends into the first mounting hole 11.
[0034] In specific application, the workpiece 100 to be processed is installed into the first mounting hole 11 of the tapping fixture by a loading device or manually. Before the workpiece 100 to be processed is installed, the elastic member 21 is in a natural state, and the end of the slide groove 221 of the limit pin 22 facing the bottom of the installation groove 12 abuts against the limit column 23. After the workpiece 100 to be processed is installed, the workpiece 100 to be processed squeezes the limit pin 22 to slide along the installation groove 12. The installation groove 12 is squeezed by the workpiece 100 to be processed and slides toward the bottom of the installation groove 12. The elastic member 21 is squeezed and deformed, and the limit column 23 also slides relative to the slide groove 221. When the end of the slide groove 221 facing the bottom of the installation groove 12 abuts against the limit column 23, the limit The positioning pin 22 reaches its maximum sliding stroke. At this time, the end of the limiting pin 22 facing away from the mounting groove 12 abuts against the workpiece 100 to be processed. The limiting pin 22 plays a role of fixing and limiting the workpiece 100 to be processed in the first mounting hole 11, reducing the shaking of the workpiece 100 to be processed during the drilling, tapping and other processes. When the workpiece 100 to be processed is cut into the first mounting hole 11, the elastic member 21 elastically deforms, and the elastic member 21 pushes the limiting pin 22 to slide along the mounting groove 12. At the same time, the limiting column 23 also slides relative to the slide groove 221. When the end of the slide groove 221 facing away from the bottom of the mounting groove 12 abuts against the limiting column 23, the limiting pin 22 reaches its maximum sliding stroke.
[0035] In this way, by setting a first mounting hole 11 and a mounting groove 12 that are interconnected on the fixture body 1, and setting the limiting structure 2 in the mounting groove 12, when the workpiece 100 to be processed is installed in the first mounting hole 11, the limiting structure 2 can lock and fix the workpiece 100 to be processed in the first mounting hole 11, avoiding the workpiece 100 to be processed from rotating relative to the first mounting hole 11 during drilling or tapping processes, thereby improving the processing quality of the workpiece 100 to be processed.
[0036] Furthermore, when the elastic member 21 is in a deformed state, the end of the limit pin 22 facing away from the elastic member 21 is located in the mounting groove 12 ; when the elastic member 21 is in a natural state, the end of the limit pin 22 facing away from the elastic member 21 is located in the first mounting hole 11 .
[0037] In this way, it can be ensured that after the workpiece 100 to be processed is installed in the first mounting hole 11, the limit pin 22 can realize the function of squeezing and limiting the workpiece to be processed; and when the workpiece 100 to be processed is installed, the limit pin 22 can be squeezed by the workpiece 100 to slide toward the bottom of the mounting groove 12, thereby realizing the installation of the workpiece 100 to be processed in the first mounting hole 11.
[0038] Furthermore, the clamp body 1 is disc-shaped and has multiple first mounting holes 11. The multiple first mounting holes 11 are arranged at intervals along the circumferential direction of the clamp body 1. The number of mounting grooves 12 and the number of limiting structures 2 are the same as the number of first mounting holes 11. The mounting grooves 12 are connected to the first mounting holes 11 one by one, and the multiple limiting structures 2 are respectively arranged in different mounting grooves 12.
[0039] In this example, there are 16 first mounting holes 11 , and the 16 first mounting holes 11 are arranged at equal intervals.
[0040] In this way, the utilization rate of the tapping fixture can be improved.
[0041] Furthermore, the clamp body 1 has a second mounting hole 13 , and the second mounting hole 13 is located at the center of the clamp body 1 .
[0042] In this way, the tapping fixture can be installed on the driving member through the second mounting hole 13. The driving member can be a motor. The tapping mechanism is set relative to a first mounting hole 11, and the drilling mechanism is set relative to another first mounting hole 11, thereby realizing automated processing of the workpiece 100 to be processed.
[0043] Furthermore, the first mounting hole 11 is obliquely provided on the fixture body 1 , and the setting direction of the first mounting hole 11 and the setting direction of the second mounting hole 13 form an angle α.
[0044] In this example, the included angle α is 32°, so that a 58° oblique thread can be processed on the workpiece 100 to be processed.
[0045] Furthermore, the fixture body 1 is made of SKD11 tool steel.
[0046] In this way, the material strength of the fixture body 1 is ensured. In summary, by providing the fixture body with a first mounting hole and a mounting slot that are interconnected, and disposing a limiting structure in the mounting slot, when the workpiece to be processed is installed in the first mounting hole, the limiting structure can lock and fix the workpiece to be processed in the first mounting hole, preventing the workpiece to be processed from rotating relative to the first mounting hole during drilling or tapping processes, thereby improving the processing quality of the workpiece to be processed.

For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
