Technical Field

[0001] This utility model relates to the field of microphone stamping fixture technology, specifically an integrated microphone stamping fixture. Background Technology

[0002] In today's electronic component manufacturing industry, microphones are key auditory components in many smart devices. Their production precision directly determines product quality and performance. In the precision stamping production process, different models of microphones often have strict and different dimensional standards, which requires that the stamping dies that are compatible with them must be highly accurate.

[0003] When the production line needs to switch to the production of microphones of different sizes, traditional fixtures require operators to disassemble the entire fixture. This process not only consumes a lot of time, but also keeps the production equipment idle, unable to carry out any effective production activities, reducing the efficiency of the production line. At the same time, frequent disassembly and assembly may also lead to increased equipment wear and tear, affecting its service life and long-term production stability. Therefore, an integrated microphone stamping fixture is needed to meet people's needs. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an integrated microphone stamping fixture, including a device body 1, a fixture body 2 installed inside the device body 1, a rotating shaft 3 installed inside the fixture body 2, a first stamping groove 4 opened on the side of the fixture body 2, multiple arc plates 8 installed on the side of the fixture body 2, slots 9 opened in the arc plates 8, a sliding groove 10 communicating with the slots 9 opened in the device body 1, a spring 11 installed in the sliding groove 10, a plug rod 12 installed in the slots 9, and multiple second stamping grooves 5 opened on the side of the fixture body 2. Multiple third stamping grooves 6 are formed on the side of body 2. The diameters of the first stamping groove 4, the second stamping groove 5, and the third stamping groove 6 are different. A movable groove 14 is formed on the side of the main body 1. A connecting rod 13 is installed on the side of the insertion rod 12. A pull plate 15 is installed on the end of the connecting rod 13 away from the insertion rod 12. A guide angle 19 is formed on the side of the arc plate 8. The end of the insertion rod 12 near the slot 9 is matched with the guide angle 19. One end of the spring 11 is installed on the inner wall of the slide groove 10, and the other end of the spring 11 is installed on the insertion rod 12. During microphone production, it is necessary to... To adjust the size of the microphone during production, pull the pull plate 15 to move the connecting rod 13 within the movable groove 14, which in turn moves the insertion rod 12 within the sliding groove 10. The spring 11 is compressed, and the front end of the insertion rod 12 separates from the slot 9, thus removing the limiting effect on the fixture body 2. Rotating the fixture body 2 causes the rotating shaft 3 to rotate within the device body 1, which in turn causes multiple balls 17 to slide within the rotating groove 16, reducing friction during the rotation of the rotating shaft 3 and making the rotation of the fixture body 2 easier. The first stamping groove 4 on the fixture body 2 is then replaced. The second stamping groove 5 or the third stamping groove 6 is rotated up to be on the same horizontal plane as the main body 1 for production. When the main body 2 of the fixture rotates, the top of the insert rod 12 abuts against the side of the main body 2 of the fixture. The arc plate 8 on the side of the main body 2 of the fixture rotates inside the main body 1 of the device. When the side of the arc plate 8 abuts against the insert rod 12, the insert rod 12 slides into the arc plate 8 through the guide angle 19. When it slides to the slot 9, the spring 11 pushes the insert rod 12 into the new slot 9, thus completing the adjustment of the first stamping groove 4 on the main body 2 of the fixture.

[0022] Example 2: Figure 2 and 3 As shown, a rotating groove 16 is provided on the side of the rotating shaft 3, and multiple balls 17 are installed in the slot 9. Multiple standard lines 18 are provided on the side of the device body 1 near the fixture body 2. Multiple marking grooves 7 that are adapted to the standard lines 18 are provided on the side of the device body 1. When the rotation is completed, the operator can observe the position of the marking grooves 7 and the standard lines 18. When the fingertip of the marking groove 7 is at the same level as the standard line 18, it indicates that the adjustment position is standard. The other features are the same as in Embodiment 1.

[0023] The working principle is as follows: During microphone production, the size of the microphone needs to be adjusted. Pulling the pull plate 15 causes the connecting rod 13 to slide in the movable groove 14, which in turn causes the insertion rod 12 to slide in the sliding groove 10. The spring 11 is compressed, and the front end of the insertion rod 12 separates from the slot 9, thus removing the limitation on the fixture body 2. By rotating the fixture body 2, the rotating shaft 3 rotates within the device body 1, which in turn causes multiple balls 17 to slide in the rotating groove 16, reducing the friction when the rotating shaft 3 rotates, making the rotation of the fixture body 2 easier. The first stamping groove 4 on the fixture body 2 is replaced, and the second stamping groove 5 or the third stamping groove 6 is rotated up to be on the same horizontal plane as the device body 1 for production. When the fixture body 2 rotates... The top of the insert rod 12 abuts against the side of the fixture body 2. The arc plate 8 on the side of the fixture body 2 rotates within the device body 1. When the side of the arc plate 8 abuts against the insert rod 12, the insert rod 12 slides into the arc plate 8 through the guide angle 19. When it slides to the slot 9, the spring 11 pushes the insert rod 12 into the new slot 9, completing the adjustment of the first stamping groove 4 on the fixture body 2. When the rotation is completed, the operator can observe the position of the marking groove 7 and the standard line 18. When the fingertip of the marking groove 7 is at the same level as the standard line 18, it indicates that the adjustment position is standard. The first stamping groove 4 can be replaced by rotating the fixture body 2 without disassembling the entire fixture body 2 for replacement, which improves production efficiency.

[0024] 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.
