Description

Technical Field

[0001] This utility model relates to the field of microphone processing technology, specifically a positioning structure for processing rotating microphone parts. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. Microphones are classified into dynamic, condenser, electret, and the recently emerging silicon micro-microphones. Most microphones are electret condenser microphones, which work by using a polymer diaphragm with permanent charge isolation. Due to their sound amplification capabilities, they are popular and widely used.

[0003] For example, patent application number 202022964289.2 discloses a clamp for processing microphone shells, including a base. A material tray is fixedly mounted on the upper left side of the base, a left pressure plate is fixedly mounted on the middle of the upper side of the base, a controller is fixedly mounted on the upper left side of the left pressure plate, a first rubber pad is fixedly mounted on the right side of the left pressure plate, a left and right clamping device is fixedly mounted on the lower right side of the first rubber pad, a clamping plate telescopic device is fixedly mounted on the upper end of the left and right clamping devices, and a front and rear clamping device is fixedly mounted on the left side of the clamping plate telescopic device. The left and right clamping devices and the front and rear clamping devices in the solution can fix the microphone shell in the front-back direction and the left and right direction, so that the device clamps the microphone shell more firmly. At the same time, the controller can control the feed of the left and right clamping devices and the front and rear clamping devices, ensuring that the pressure is not too high and the microphone shell is broken while clamping the microphone shell.

[0004] Based on the search of the aforementioned patents and the discovery of devices in the existing technology, the aforementioned devices can solve the problem that the internal components of the microphone assembly are often directly installed inside the shell. During the assembly process, workers often need to hold the shell to process or assemble it, which undoubtedly increases the difficulty of processing the microphone shell. Some simple clamping tools can only clamp on one side, and the fixation of the shell is not firm. If too much force is used, the microphone shell can easily be crushed.

[0005] However, during use, because some parts of the microphone are cylindrical and some parts have angular requirements during processing, it is difficult to rotate and position the cylindrical parts, resulting in poor positioning and reduced processing efficiency of microphone parts. Summary of the Invention

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a positioning structure for machining rotating microphone parts. This structure has the advantage of facilitating the positioning and angle adjustment of cylindrical parts. It solves the problem that because some microphone parts are cylindrical and some parts have angle requirements during machining, it is difficult to achieve rotational adjustment and positioning of cylindrical parts, resulting in poor positioning and reduced machining efficiency of microphone parts.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for machining rotating microphone parts, comprising a base plate and a side plate, wherein the bottom of the side plate is fixedly connected to the rear side of the top of the base plate, a positioning groove is provided on the top of the front of the side plate, a threaded groove is provided on the top of the right side of the side plate, a set screw is threadedly connected inside the threaded groove, a crank rocker is fixedly connected to the right side of the set screw, a side positioning post is fixedly connected to the left side of the set screw, a rubber contact sleeve is sleeved on the left side of the side positioning post, a movable component is provided on the left side of the side positioning post, and an angle measuring mechanism is embedded in the top of the front of the side plate.

[0008] In a preferred embodiment of this invention, the movable component includes a movable groove, which is located on the left side of the side positioning post. A movable block is movably connected inside the movable groove, and both the movable block and the movable groove have a T-shaped cross-section.

[0009] As a preferred embodiment of the present invention, the angle measuring mechanism includes a disc protractor, which is embedded in the top of the front of the side plate. A transmission ring is provided inside the disc protractor, and a pointer is fixedly connected to the right side of the front of the transmission ring.

[0010] As a preferred embodiment of this utility model, both sides of the left side of the movable block are provided with inlay grooves, and inlay blocks are inlaid inside the inlay grooves. The inlay blocks are fixedly connected to both sides of the left side of the inner wall of the rubber contact sleeve.

[0011] As a preferred embodiment of this invention, a limiting slip ring is fitted on the surface of the transmission ring, and a limiting ring groove is formed on the inner wall of the disc protractor, with the surface of the limiting slip ring slidably connected to the inner wall of the limiting ring groove.

[0012] As a preferred embodiment of this invention, the inner wall of the transmission ring is fixedly connected with a rubber anti-slip strip, and the rubber anti-slip strip is provided in a plurality of pieces and is distributed in a ring at equal intervals.

[0013] As a preferred embodiment of this utility model, the left side of the rubber contact sleeve is provided with a multi-directional anti-slip groove, and the multi-directional anti-slip groove is provided in a plurality of them and is distributed in a ring at equal intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a positioning groove, allows a cylindrical part to be inserted into the positioning groove and rotated to adjust the angle. After the angle adjustment is completed, the user can move the side positioning post to the left to press and position the cylindrical part in the positioning groove. This solves the problem that some parts of the microphone are cylindrical and some parts have angle requirements during processing, making it difficult to rotate and position the cylindrical parts, which leads to poor positioning and reduced microphone part processing efficiency. This invention achieves the effect of facilitating the positioning and angle adjustment of cylindrical parts.

[0016] 2. By setting up a movable component, when the rubber contact sleeve comes into contact with the cylindrical part during the rotation and movement of the side positioning column, the rubber contact sleeve will be affected by friction, causing the movable block to be resisted. Then, the side positioning column only has the clamping force on the cylindrical part, but not the rotational force on the cylindrical part, thus ensuring the use effect. Furthermore, by utilizing the fact that the cross-sections of the movable block and the movable groove are both T-shaped, the situation of the movable block and the movable groove being separated is avoided.

[0017] 3. This utility model, by setting an angle measuring mechanism, allows the cylindrical part to be inserted into the positioning groove and rotated for adjustment by the user. The cylindrical part will drive the transmission ring to rotate synchronously through the friction between the cylindrical part and the transmission ring. Then, the transmission ring will drive the pointer to rotate synchronously. The position of the pointer on the front of the disc protractor is then used to quickly determine the angle of the cylindrical part, thus avoiding the situation where the adjusted angle does not meet the requirements.

[0022] 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.

[0023] like Figures 1 to 3 As shown, the positioning structure for machining rotating microphone parts provided by this utility model includes a base plate 1 and a side plate 2. The bottom of the side plate 2 is fixedly connected to the rear side of the top of the base plate 1. A positioning groove 3 is provided on the top of the front of the side plate 2, and a threaded groove 4 is provided on the top of the right side of the side plate 2. A set screw 5 is threaded inside the threaded groove 4. A crank rocker arm 6 is fixedly connected to the right side of the set screw 5. A side positioning post 7 is fixedly connected to the left side of the set screw 5. A rubber contact sleeve 8 is sleeved on the left side of the side positioning post 7. A movable component 9 is provided on the left side of the side positioning post 7. An angle measuring mechanism 10 is embedded in the top of the front of the side plate 2.

[0024] refer to Figure 3 The active component 9 includes an active groove 91, which is located on the left side of the side positioning post 7. An active block 92 is movably connected inside the active groove 91. The cross-sections of the active block 92 and the active groove 91 are both T-shaped.

[0025] As a technical optimization of this utility model, by setting the movable component 9, when the rubber contact sleeve 8 contacts the cylindrical part during the rotation and movement of the side positioning column 7, the rubber contact sleeve 8 will be affected by friction, causing the movable block 92 to be resisted. Then, the side positioning column 7 only has the clamping force on the cylindrical part, but not the rotational force on the cylindrical part, thereby ensuring the use effect. Furthermore, by utilizing the fact that the cross-sections of the movable block 92 and the movable groove 91 are both T-shaped, the situation of the movable block 92 and the movable groove 91 being separated is avoided.

[0026] refer to Figure 2 The angle measuring mechanism 10 includes a disc protractor 101, which is embedded in the top of the front of the side plate 2. A transmission ring 102 is provided inside the disc protractor 101, and a pointer 103 is fixedly connected to the right side of the front of the transmission ring 102.

[0027] As a technical optimization of this utility model, by setting an angle measuring mechanism 10, when the user inserts the cylindrical part into the positioning groove 3 and rotates it for adjustment, the cylindrical part will synchronously drive the transmission ring 102 to rotate through the friction with the transmission ring 102. Then, the transmission ring 102 will synchronously drive the pointer 103 to rotate. Then, the position of the disc protractor 101 pointed to by the pointer 103 is used to quickly determine the current angle of rotation adjustment of the cylindrical part, so as to avoid the adjusted angle not meeting the requirements.

[0028] refer to Figure 3 The movable block 92 has inlay grooves 11 on both sides of the left side, and inlay blocks 12 are inlaid inside the inlay grooves 11. The inlay blocks 12 are fixedly connected to the two sides of the left side of the inner wall of the rubber contact sleeve 8.

[0029] As a technical optimization of this utility model, by setting the inlay groove 11 and the inlay block 12, when the rubber contact sleeve 8 ages and is damaged after long-term use and needs to be replaced, the user can rotate the set screw 5 to move the rubber contact sleeve 8 into the positioning groove 3. Then the user can reach out and move into the positioning groove 3 to hold the rubber contact sleeve 8 and pull it out directly, so that the inlay groove 11 and the inlay block 12 are separated. Then the inlay block 12 on the new rubber contact sleeve 8 is inserted into the inner wall of the corresponding inlay groove 11 to install the new rubber contact sleeve 8.

[0030] refer to Figure 2 A limiting slip ring 13 is fitted on the surface of the transmission ring 102, and a limiting ring groove 14 is formed on the inner wall of the disc protractor 101. The surface of the limiting slip ring 13 is slidably connected to the inner wall of the limiting ring groove 14.

[0031] As a technical optimization of this utility model, by setting a limiting slip ring 13 and a limiting ring groove 14, the limiting slip ring 13 will be driven to rotate synchronously during the rotation of the transmission ring 102. Then the limiting slip ring 13 will rotate along the inner wall of the limiting ring groove 14, thereby limiting the transmission ring 102 in the front and back and preventing the transmission ring 102 from falling off.

[0032] refer to Figure 2 A rubber anti-slip strip 15 is fixedly connected to the inner wall of the transmission ring 102. Several rubber anti-slip strips 15 are provided and are distributed in a ring at equal intervals.

[0033] As a technical optimization of this utility model, by setting a rubber anti-slip strip 15, when the user inserts the cylindrical part into the positioning groove 3 and rotates the cylindrical part for adjustment, the cylindrical part will contact the transmission ring 102 through the rubber anti-slip strip 15, thereby greatly improving the friction between the cylindrical part and the transmission ring 102, preventing slippage during rotation, and preventing errors in the angle data of the cylindrical part adjustment.

[0034] refer to Figure 3 The left side of the rubber contact sleeve 8 has a multi-directional anti-slip groove 16, which is provided in a ring and is evenly distributed.

[0035] As a technical optimization of this utility model, by setting multi-directional anti-slip grooves 16, when the side positioning post 7 presses the cylindrical part against the rubber contact sleeve 8 for positioning, the left side of the rubber contact sleeve 8 will contact the cylindrical part through the multi-directional anti-slip grooves 16, thereby improving the front-to-back and up-to-down friction between the cylindrical part and the rubber contact sleeve 8, and further improving the positioning stability.

[0036] The working principle and usage process of this utility model are as follows: When the user needs to position and process a cylindrical part, the user first inserts the cylindrical part into the positioning groove 3. Then, the user can rotate the cylindrical part to adjust the angle within the positioning groove 3. After the angle adjustment is completed, the user can rotate the crank rocker 6 to rotate the set screw 5. Then, using the threaded connection between the set screw 5 and the threaded groove 4, the set screw 5 will move to the left during rotation. The set screw 5 will then drive the side positioning pin 7 to move to the left to press and position the cylindrical part in the positioning groove 3. During the positioning process, the side positioning pin 7 will press and position the cylindrical part through the rubber contact sleeve 8 to avoid damaging the cylindrical part.

[0037] During the rotation and movement of the side positioning post 7, when the rubber contact sleeve 8 comes into contact with the cylindrical part, the rubber contact sleeve 8 will be affected by friction, causing the movable block 92 to be resisted. Then, the side positioning post 7 only has the clamping force on the cylindrical part, but not the rotational force on the cylindrical part, thus ensuring the use effect. Furthermore, since the cross-sections of the movable block 92 and the movable groove 91 are both T-shaped, the situation of the movable block 92 and the movable groove 91 disengaging is avoided.

[0038] When the user inserts the cylindrical part into the positioning slot 3 and rotates it for adjustment, the cylindrical part will synchronously drive the transmission ring 102 to rotate through the friction with the transmission ring 102. Then, the transmission ring 102 will synchronously drive the pointer 103 to rotate. Then, the position of the disc protractor 101 pointed to by the pointer 103 is used to quickly determine the current rotation angle of the cylindrical part, so as to avoid the adjustment angle not meeting the requirements.

[0039] In summary, this positioning structure for machining rotating microphone parts solves the problem of poor positioning efficiency due to the difficulty in rotating and positioning cylindrical parts caused by the cylindrical shape of some microphone parts and the angular requirements of some parts during machining.
