Description

Technical Field

[0001] This utility model relates to the field of connector processing technology, and in particular to a precision machining positioning fixture for connectors. Background Technology

[0002] In the precision machining of connectors, especially in the pin insertion process of M12 connectors, extremely high requirements are placed on the positioning accuracy and clamping stability of the connector. Positioning fixtures, as key equipment ensuring the smooth progress of this process, directly affect the accuracy and efficiency of the pin insertion operation. Precise positioning ensures the pins are in the correct position, preventing connector damage or performance failure due to deviations, while stable clamping prevents the connector from shaking during machining, providing a reliable foundation for precision machining.

[0003] When performing pin insertion operations on M12 connectors, we found that the current positioning fixtures have poor adaptability and can often only support and fix connectors of specific specifications. When processing connectors of different specifications, it is necessary to frequently change the fixtures, which is cumbersome and time-consuming, and seriously affects the processing efficiency. On the other hand, the positioning accuracy and automation are insufficient, and it relies heavily on manual positioning. This not only makes it easy for human operation errors to cause inaccurate positioning, affecting the pin insertion quality, but also increases labor costs, making it difficult to meet the needs of efficient and precise finishing. Utility Model Content

[0004] The main purpose of this utility model is to provide a connector precision machining positioning fixture, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a connector precision machining positioning fixture, including a connector seat, a C-shaped support seat is provided on the upper side of the middle of the connector seat, a clamping mechanism is provided on the upper part of the C-shaped support seat, a connector body is provided in the middle of the clamping mechanism, and a positioning mechanism is provided at the lower part of the clamping mechanism;

[0006] The clamping mechanism includes a connecting box, multiple limiting grooves, multiple clamping blocks, a threaded disc, and a driving assembly. The multiple limiting grooves are equally spaced on the upper part of the connecting box, and the limiting grooves and clamping blocks correspond one-to-one. The outer periphery of the clamping block is slidably connected to the inside of the limiting groove. The lower part of the clamping block is disposed on the upper part of the threaded disc, and the lower part of the threaded disc is disposed on the upper part of the driving assembly. The lower part of the driving assembly is installed on the inner bottom wall of the connecting box.

[0007] Preferably, an anti-slip rubber pad is provided on the side of the clamping block adjacent to it.

[0008] Preferably, the drive assembly includes a worm gear, a worm, and a knob. The lower part of the worm gear is rotatably connected to the bottom wall of the connecting box, the upper part of the worm gear is fixedly connected to the lower part of the threaded disc, the front and rear ends of the worm are rotatably connected to the lower part of the connecting box, and the front end of the worm gear penetrates the wall of the connecting box and is fixedly connected to the middle of the knob. The worm gear and the worm are meshed with each other.

[0009] Preferably, there are at least four limiting grooves, and the limiting grooves are arranged in a ring at equal intervals on the upper part of the connecting box.

[0010] Preferably, the positioning mechanism includes a servo motor, a gear, a gear ring, and a laser sensor. The laser sensor is installed on one side of the upper part of the connecting seat. The upper part of the gear ring is fixedly connected to the lower part of the connecting box. The gear ring is sleeved on the outer periphery of the C-shaped support seat. The lower part of the servo motor is installed on the upper part of the connecting seat. The middle part of the gear is fixedly connected to the upper output end of the servo motor. The gear and the gear ring mesh with each other.

[0011] Preferably, the laser sensor and the servo motor are electrically connected to an external controller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By rotating the knob, multiple clamping blocks can be driven to slide within the limiting groove to adjust the spacing. This allows for both the adaptation of connector bodies of the same specifications, enabling stable clamping upon direct insertion, and the quick adjustment to accommodate connector bodies of different specifications. This eliminates the need to change tooling and significantly improves operational flexibility and efficiency.

[0014] 2. After clamping and fixing, the connector body can rotate under the transmission of servo motor, gear and gear ring. When the laser sensor detects the positioning groove on the lower part of the connector body, the servo motor will be stopped by the external controller to automatically complete the precise positioning, ensuring the accuracy of precision machining operations such as pin insertion and reducing manual positioning errors.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4 As shown, a connector precision machining positioning fixture includes a connector base 1, a C-shaped support base 2 is provided on the upper side of the middle of the connector base 1, a clamping mechanism 3 is provided on the upper part of the C-shaped support base 2, a connector body 4 is provided in the middle of the clamping mechanism 3, and a positioning mechanism 5 is provided at the lower part of the clamping mechanism 3.

[0022] In this embodiment, the clamping mechanism 3 includes a connecting box 301, multiple limiting grooves 302, multiple clamping blocks 303, a threaded disc 304, and a driving assembly 305. The multiple limiting grooves 302 are evenly spaced on the upper part of the connecting box 301. Each limiting groove 302 corresponds to one clamping block 303, and the outer periphery of each clamping block 303 is slidably connected to the inside of the limiting groove 302. The lower part of each clamping block 303 is positioned on the upper part of the threaded disc 304, and the lower part of the threaded disc 304 is positioned on the upper part of the driving assembly 305. The lower part of the driving assembly 305 is installed on the inner bottom wall of the connecting box 301. A protective device is provided on the side of each clamping block 303 that is close to it. The sliding rubber pad and the drive assembly 305 include a worm gear 3051, a worm 3052 and a knob 3053. The lower part of the worm gear 3051 is rotatably connected to the bottom wall of the connecting box 301, and the upper part of the worm gear 3051 is fixedly connected to the lower part of the threaded disc 304. The front and rear ends of the worm 3052 are rotatably connected to the lower part of the connecting box 301. The front end of the worm gear 3051 penetrates the wall of the connecting box 301 and is fixedly connected to the middle of the knob 3053. The worm gear 3051 and the worm 3052 mesh with each other. There are at least four limiting grooves 302, and the limiting grooves 302 are opened in an annular shape at equal intervals on the upper part of the connecting box 301.

[0023] Specifically, firstly, the knob 3053 in the clamping mechanism 3 is rotated. The knob 3053 drives the worm gear 3052, which is fixedly connected to it, to rotate. Since the worm gear 3052 and the worm wheel 3051 mesh with each other, the rotation of the worm gear 3052 will drive the worm wheel 3051 to rotate, thereby causing the threaded disc 304 fixedly connected to the upper part of the worm wheel 3051 to rotate synchronously. When the threaded disc 304 rotates, the multiple clamping blocks 303 on its upper part will slide in the corresponding limiting grooves 302. Since the limiting grooves 302 are equally spaced on the upper part of the connecting box 301 and are distributed in a ring, the clamping blocks 303 will move closer to each other under the action of the threaded disc 304 until the multiple clamping blocks 303... The space formed by the clamping blocks 303 is just enough to place the connector body 4, thereby supporting the connector body 4 and facilitating pin insertion. Since the anti-slip rubber pad on the side of the clamping block 303 is in contact with the outer periphery of the connector body 4 and generates a certain friction force, it prevents the connector body 4 from shaking. When performing pin insertion on connector bodies 4 of the same specification, the connector body 4 can be placed directly into the space formed by the clamping block 303 without further adjustment. When it is necessary to insert pins on connector bodies 4 of different specifications, the knob 3053 is rotated again, and the distance between the clamping blocks 303 is adjusted through the above transmission process to adapt to the new specification of connector body 4.

[0024] In this embodiment, the positioning mechanism 5 includes a servo motor 501, a gear 502, a gear ring 503, and a laser sensor 504. The laser sensor 504 is installed on one side of the upper part of the connecting seat 1. The upper part of the gear ring 503 is fixedly connected to the lower part of the connecting box 301. The gear ring 503 is sleeved on the outer periphery of the C-shaped support seat 2. The lower part of the servo motor 501 is installed on the upper part of the connecting seat 1. The middle part of the gear 502 is fixedly connected to the upper output end of the servo motor 501. The gear 502 and the gear ring 503 mesh with each other. The laser sensor 504 and the servo motor 501 are electrically connected to an external controller.

[0025] Specifically, after clamping is completed, the servo motor 501 in the positioning mechanism 5 is started. The output end of the servo motor 501 drives the gear 502 to rotate. Since the gear 502 and the gear ring 503 mesh with each other, the rotation of the gear 502 will drive the gear ring 503 to rotate. The upper part of the gear ring 503 is fixedly connected to the lower part of the connector box 301, thereby driving the entire clamping mechanism 3 and the clamped connector body 4 to rotate. When the groove on the lower surface of the connector body 4 used for positioning the male head rotates to the detection position of the laser sensor 504, the laser sensor 504 will send an electrical signal to the external controller. After receiving the signal, the external controller controls the servo motor 501 to stop running. At this time, the connector body 4 completes the positioning and the pin insertion operation can be performed.

[0026] Working principle:

[0027] In use, first rotate the knob 3053 in the clamping mechanism 3. The knob 3053 drives the worm 3052 fixedly connected to it to rotate. Since the worm 3052 and the worm wheel 3051 mesh with each other, the rotation of the worm 3052 will drive the worm wheel 3051 to rotate, thereby causing the threaded disc 304 fixedly connected to the upper part of the worm wheel 3051 to rotate synchronously. When the threaded disc 304 rotates, the multiple clamping blocks 303 on its upper part will slide in the corresponding limiting grooves 302. Since the limiting grooves 302 are equally spaced on the upper part of the connector box 301 and are distributed in a ring, the clamping blocks 303 will move closer to each other under the action of the threaded disc 304 until the space formed between the multiple clamping blocks 303 is just enough to place the connector body 4, thereby achieving support for the connector body 4 and facilitating pin insertion. Since the anti-slip rubber pad on the side of the clamping block 303 that is close to each other will contact the outer periphery of the connector body 4 and generate a certain friction force, it will prevent the connector body 4 from shaking. When performing pin insertion operation on connector bodies 4 of the same specification, the connector is directly inserted. The connector body 4 can be placed into the space formed by the clamping block 303 without further adjustment. When it is necessary to insert pins into the connector body 4 of different specifications, the knob 3053 is rotated again to adjust the spacing between the clamping blocks 303 through the above transmission process to adapt to the new specification of the connector body 4. After clamping is completed, the servo motor 501 in the positioning mechanism 5 is started. The output end of the servo motor 501 drives the gear 502 to rotate. Since the gear 502 and the gear ring 503 mesh with each other, the rotation of the gear 502 will drive the gear ring 503 to rotate. The upper part of the gear ring 503 is fixedly connected to the lower part of the connector box 301, thereby driving the entire clamping mechanism 3 and the clamped connector body 4 to rotate. When the groove on the lower surface of the connector body 4 used for positioning the male head rotates to the detection position of the laser sensor 504, the laser sensor 504 will send an electrical signal to the external controller. After receiving the signal, the external controller controls the servo motor 501 to stop running. At this time, the connector body 4 is positioned and the pin insertion operation can be performed.
