Description

Technical Field

[0001] This utility model relates to the field of industrial connector manufacturing technology, specifically a processing fixture for industrial connector manufacturing. Background Technology

[0002] The core of industrial connector production is to achieve high reliability, anti-interference and durability of products in complex industrial environments through precision manufacturing, material adaptation and full-process quality control. Its core production process includes material selection and pretreatment, precision machining, assembly and testing. Among them, precision machining includes precision machining of contacts, precision machining of insulators and precision machining of shells.

[0003] In the current technology, precision machining of the outer shell requires the use of a machining fixture to fix the connector shell, and then the use of turning tools to perform milling, drilling and turning processes on the connector shell. In practical applications, the fixing of circular connector housings consisting of a cylindrical component and a square skirt is achieved by either using a V-shaped clamp to fix the cylindrical component or using a clamping plate to fix the square skirt. If a V-shaped clamp is used, the clamping force is concentrated on the two contact lines, resulting in significant localized force on the thin-walled cylindrical component and causing localized deformation. Furthermore, the square skirt is suspended, and when drilling holes in it, the openings are bent due to the downward drilling force. If a clamping plate is used, the clamping force is concentrated on both sides of the skirt, causing localized deformation of the thin-walled skirt. Since the clamping plate only fixes the skirt, the cylindrical component extends out in a cantilever shape, increasing vibration amplitude during processing and affecting machining accuracy. Therefore, a machining fixture for industrial connector production is proposed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a processing fixture for industrial connector production. It offers advantages such as stable positioning and avoidance of excessive local stress. It solves the problem of fixing circular connector shells composed of a cylindrical component and a square skirt. Methods include fixing the cylindrical component with a V-shaped clamp or fixing the square skirt with a clamping plate. If a V-shaped clamp is used, the clamping force is concentrated on two contact lines, resulting in significant localized force on the thin-walled cylindrical component, causing localized deformation. Furthermore, the square skirt is suspended, leading to localized bending at the drilling opening due to the downward drilling force. If a clamping plate is used, the clamping force is concentrated on both sides of the skirt, causing localized deformation of the thin-walled skirt. The clamping plate only fixes the skirt, leaving the cylindrical component cantilevered, increasing vibration amplitude during processing and affecting processing accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a processing fixture for industrial connector production, comprising a mounting base and a cylindrical connector housing, wherein two connecting components are provided on the mounting base, each of the two connecting components is provided with a positioning component, and a control component for controlling the two connecting components to move towards each other is provided on the mounting base; The connecting component includes an M-shaped box, with cover plates fixedly installed at both ends of the M-shaped box, and elastic components provided inside the M-shaped box; The positioning component includes a T-shaped part located at the top of the M-shaped box. A V-shaped part is provided on one side of the T-shaped part for fixing the cylindrical connector housing. The V-shaped part is slidably engaged with the V-groove of the M-shaped box. Two guide rods are fixedly installed at the bottom of the T-shaped part, both of which penetrate the cover plate and extend to the outside of the M-shaped box. The guide rods are slidably connected to the cover plate. The elastic component is provided on the two guide rods. The control component includes an electric push rod fixedly mounted on the mounting base, and the telescopic end of the electric push rod is fixedly connected to one of the M-shaped boxes. The mounting base is provided with a linkage component for linking the two M-shaped boxes.

[0006] Furthermore, a rectangular groove is provided on the top of the mounting base, and the rectangular groove is slidably connected to two M-shaped boxes respectively. Two through grooves are provided on the inner wall of the rectangular groove, and one end of the guide rod passes through the through groove.

[0007] Furthermore, the elastic component includes a pressure plate fixedly installed on two guide rods in the positioning component, and the pressure plate is slidably connected to the inside of the M-shaped box. Two springs are fixedly installed on the bottom of the pressure plate, and the two springs are respectively sleeved on the two guide rods in the positioning component. The bottom of the springs is fixedly connected to the bottom cover plate in the M-shaped box.

[0008] Furthermore, the linkage component includes a gear rotatably mounted at the center of the rectangular slot, and racks meshing with the gear are fixedly mounted on opposite sides of the two M-shaped boxes, with the two racks being symmetrically distributed around the central axis of the gear.

[0009] Furthermore, the cylindrical connector housing includes a cylindrical member and a square skirt, with the square skirt disposed on the outer surface of the cylindrical member.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This processing fixture for industrial connector production uses an electric push rod to drive an M-shaped box to move. Through the meshing of gears and two symmetrical racks, the two M-shaped boxes move synchronously towards each other along a rectangular groove. The V-shaped part forms a centering clamp for the cylindrical part and disperses the clamping force. The T-shaped part forms a comprehensive limiting support for the square skirt, avoiding excessive local stress. This solves the problems of local deformation of the cylindrical part and bending of the square skirt caused by the V-shaped fixture only fixing the cylindrical part, as well as the problems of skirt deformation and cantilever vibration of the cylindrical part caused by the clamping plate fixture only fixing the skirt. 2. In this industrial connector manufacturing processing fixture, the drilling impact force is transmitted to the guide rod through the T-shaped part. The guide rod slides down along the cover plate and through groove, driving the pressure plate to compress the spring. The elastic deformation of the spring is used to convert the impact force into elastic potential energy, thereby achieving the buffering and unloading of the impact force. This avoids the drilling force from acting directly on the square skirt during drilling, which would cause local bending and deformation at the opening. 3. The processing fixture for industrial connector production features a symmetrical V-shaped structure that centers and positions the cylindrical part, ensuring coaxiality between the cylindrical part's central axis and the machine tool spindle. The precise meshing of the gears and racks ensures synchronous movement of the two M-shaped boxes, resulting in a uniform distribution of clamping force on the cylindrical part by the V-shaped part. Meanwhile, the T-shaped part's limiting support for the square skirt further suppresses vibration, preventing the cylindrical part from being cantilevered after the clamping fixture fixes the skirt, which would cause large vibration amplitude during processing, leading to machining errors such as hole offset and uneven groove width.

[0013] 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.

[0014] Example 1: Please refer to Figure 1-5 This embodiment of a processing fixture for industrial connector production includes a mounting base 1 and a cylindrical connector housing 5. The mounting base 1 is provided with two connecting components 2, each of which is provided with a positioning component 3. The mounting base 1 is also provided with a control component 4 for controlling the two connecting components 2 to move towards each other.

[0015] The cylindrical connector housing 5 includes a cylindrical member 51 and a square skirt 52, with the square skirt 52 disposed on the outer surface of the cylindrical member 51. It should be noted that the positioning component 3 achieves multiple restrictions on the cylindrical part 51 and the square skirt 52, realizing synchronous linkage positioning and bidirectional clamping and fixing. This solves the problems of local deformation of the cylindrical part 51 and bending of the square skirt 52 caused by the traditional V-shaped clamp only fixing the cylindrical part 51, as well as the problems of skirt deformation and cantilever vibration of the cylindrical part 51 caused by the clamping plate clamp only fixing the skirt.

[0016] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the connecting component 2 includes an M-shaped box 21, with cover plates 22 fixedly installed at both ends of the M-shaped box 21, and an elastic component 23 provided inside the M-shaped box 21; The positioning component 3 includes a T-shaped part 31 located at the top of the M-shaped box 21. A V-shaped part 32 for fixing the cylindrical connector housing 5 is provided on one side of the T-shaped part 31, and the V-shaped part 32 is slidably engaged with the V-shaped groove of the M-shaped box 21. Two guide rods 33 are fixedly installed at the bottom of the T-shaped part 31, both of which penetrate the cover plate 22 and extend to the outside of the M-shaped box 21. The guide rods 33 are slidably connected to the cover plate 22. An elastic component 23 is provided on the two guide rods 33. The control component 4 includes an electric push rod 41 fixedly mounted on the mounting base 1, and the telescopic end of the electric push rod 41 is fixedly connected to one of the M-shaped boxes 21. The mounting base 1 is provided with a linkage component 42 for linking the two M-shaped boxes 21.

[0017] It should be noted that the V-groove of the M-shaped box 21 slides into the V-shaped part 32 of the positioning component 3, which not only provides a guide for the movement of the V-shaped part 32, but also ensures that the contact between the V-shaped part 32 and the outer circle of the cylinder 51 is a symmetrical line contact through the centering characteristics of the V-shaped structure. Compared with the single contact line of the traditional V-shaped clamp, the clamping force is dispersed, and the cylinder 51 is prevented from being deformed by concentrated local force. The cover plate 22 seals the internal space of the M-shaped box 21 on the one hand, and provides sliding support for the guide rod 33 on the other hand, ensuring the straightness of the vertical movement of the positioning component 3. The T-shaped part 31 and the V-shaped part 32 of the positioning component 3 are integrated structures. The inner wall of the T-shaped part 31 is designed to fit the square skirt 52, which can achieve full fit and limit on both sides of the square skirt 52, solving the problem of the skirt being suspended and unsupported in traditional V-shaped clamps. The guide rod 33 passes through the cover plate 22 and is slidably connected, which not only achieves a rigid connection between the positioning component 3 and the elastic component 23, but also provides a stable movement trajectory for the elastic buffer, preventing the positioning component 3 from shifting during buffering.

[0018] The elastic component 23 includes a pressure plate 231 fixedly installed on two guide rods 33 in the positioning component 3, and the pressure plate 231 is slidably connected to the inside of the M-shaped box 21. Two springs 232 are fixedly installed at the bottom of the pressure plate 231, and the two springs 232 are respectively sleeved on the two guide rods 33 in the positioning component 3. The bottom of the springs 232 is fixedly connected to the bottom cover plate 22 in the M-shaped box 21.

[0019] It should be noted that the elastic component 23 is linked with the guide rod 33 through the combination of the pressure plate 231 and the double springs 232. The pressure plate 231 concentrates the force of the two guide rods 33 to the springs 232. The symmetrical arrangement of the double springs 232 ensures the force is balanced and avoids the tilting of the positioning component 3 caused by the compression of the spring 232 on one side. It is specially designed for the downward impact force of the drilling process. The elastic deformation of the springs 232 absorbs the impact force and solves the problem of bending at the opening of the square skirt 52 caused by the lack of buffer in traditional fixtures. The electric push rod 41 provides linear driving force, and the linkage component 42 ensures that the two M-shaped boxes 21 move synchronously in opposite directions, ensuring that the V-shaped part 32 of the two positioning parts 3 simultaneously fits the cylindrical part 51 and the T-shaped part 31 simultaneously fits the square skirt 52, avoiding workpiece displacement caused by unilateral clamping and further improving positioning accuracy.

[0020] Using the above technical solution, as the two M-shaped boxes 21 move, the V-shaped part 32 of the positioning component 3 contacts the outer surface of the cylindrical part 51. The centering characteristic of the V-shaped structure is used to accurately position the cylindrical part 51. Meanwhile, the T-shaped part 31 moves synchronously with the positioning component 3. At this time, the inner wall of the T-shaped part 31 is tightly fitted with both sides of the square skirt 52. The electric push rod 41 stops moving, thus completing the clamping and fixing of the cylindrical part 51 and the limiting support of the square skirt 52. The workpiece is in a completely fixed state. When milling and turning of the cylindrical part 51 and drilling of the square skirt 52 are performed using turning tools, when the tool generates a downward drilling force during the drilling process, this force is transmitted to the T-shaped part 31 through the square skirt 52, which in turn pushes the guide rod 33 to slide downward along the cover plate 22 and the through groove 12. The guide rod 33 drives the pressure plate 231 to move downward synchronously, compressing the spring 232. The elastic deformation of the spring 232 absorbs most of the downward impact force, preventing bending deformation of the square skirt 52 due to excessive local force at the opening. The centering clamping of the cylindrical part 51 by the V-shaped part 32 and the limiting support of the square skirt 52 by the T-shaped part 31 effectively limit the cantilever vibration of the cylindrical part 51, ensuring that the workpiece has no displacement or shaking during the processing.

[0021] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, a rectangular groove 11 is provided on the top of the mounting base 1, and the rectangular groove 11 is slidably connected to two M-shaped boxes 21 respectively. Two through grooves 12 are provided on the inner wall of the rectangular groove 11, and one end of the guide rod 33 passes through the through groove 12.

[0022] The linkage component 42 includes a gear 421 rotatably mounted at the center of the rectangular slot 11. Each of the two M-shaped boxes 21 has a rack 422 fixedly mounted on one side of the opposite side, which meshes with the gear 421. The two racks 422 are symmetrically distributed around the central axis of the gear 421. It should be noted that the rectangular groove 11 of the mounting base 1 slides with the two M-shaped boxes 21, providing high-precision linear guidance for the M-shaped boxes 21, avoiding lateral offset during movement, ensuring that the movement trajectories of the two connecting components 2 are parallel and symmetrical, and providing a basis for centering and positioning. The dimensions of the through groove 12 are adapted to the guide rod 33, which allows the guide rod 33 to slide up and down with the positioning component 3, and restricts the lateral swing of the guide rod 33 through the side wall of the through groove 12, ensuring the stability of the positioning component 3 during the elastic buffering process and avoiding workpiece displacement caused by the shaking of the guide rod 33 during buffering. The gear 421 of the linkage component 42 meshes with two racks 422, and the two racks 422 are symmetrically distributed along the central axis of the gear 421. When the electric push rod 41 drives one M-shaped box 21 to move, its rack 422 drives the gear 421 to rotate. The gear 421 synchronously drives the rack 422 on the other side to move in the opposite direction, ensuring that the moving distance of the two M-shaped boxes 21 is completely consistent and the speed is completely synchronized. Compared with traditional manual adjustment or single-sided drive without linkage, this matching method solves the centering deviation problem caused by the asynchronous clamping of the two positioning components 3, so that the clamping force of the V-shaped part 32 on the cylindrical part 51 is symmetrically distributed, and the limiting force of the T-shaped part 31 on the square skirt 52 is balanced, further improving the stability and positioning accuracy of the workpiece fixation.

[0023] Using the above technical solution, after receiving the command, the electric push rod 41 begins to retract, driving the M-shaped box 21 fixed thereto to slide along the rectangular groove 11 towards the workpiece. The rack 422 on the M-shaped box 21 moves synchronously, driving the gear 421 at the center of the rectangular groove 11 to rotate. When the gear 421 rotates, it drives the rack 422 meshing with it on the other side to move in the opposite direction synchronously, thereby driving the other M-shaped box 21 to slide along the rectangular groove 11 towards the workpiece, ultimately achieving synchronous opposite movement of the two M-shaped boxes 21.

[0024] The working principle of the above embodiments is as follows: When the processing fixture for industrial connector production is in use, the fixture is in the initial open state, the electric push rod 41 is in the extension limit position, and the M-shaped box 21 fixed therewith is located at one end of the rectangular groove 11. Through the meshing transmission of the gear 421 and the two racks 422 of the linkage component 42, the other M-shaped box 21 is simultaneously located at the other end of the rectangular groove 11, and a space sufficient to accommodate the cylindrical connector housing 5 is formed between the two positioning components 3. The elastic component 23 is in a naturally extended state, the spring 232 is not compressed, the pressure plate 231 is located in the upper part of the M-shaped box 21 under the support of the spring 232, and the guide rod 33 remains vertical along the cover plate 22 and the through groove 12. The operator places the cylindrical connector housing 5 between the two positioning parts 3, while positioning the square skirt 52 on the two T-shaped parts 31; When the control component 4 is activated, the electric push rod 41 receives the command and begins to retract, causing the M-shaped box 21 fixed to it to slide along the rectangular groove 11 towards the workpiece. The rack 422 on the M-shaped box 21 moves synchronously, driving the gear 421 at the center of the rectangular groove 11 to rotate. When the gear 421 rotates, it drives the rack 422 meshing with it on the other side to move in the opposite direction synchronously, thereby driving the other M-shaped box 21 to slide along the rectangular groove 11 towards the workpiece, ultimately achieving synchronous opposite movement of the two M-shaped boxes 21. As the two M-shaped boxes 21 move, the V-shaped part 32 of the positioning component 3 contacts the outer surface of the cylindrical part 51. The centering characteristic of the V-shaped structure accurately positions the cylindrical part 51. Meanwhile, the T-shaped part 31 moves synchronously with the positioning component 3. At this time, the inner wall of the T-shaped part 31 is tightly fitted with both sides of the square skirt 52. The electric push rod 41 stops moving, completing the clamping and fixing of the cylindrical part 51 and the limiting support of the square skirt 52. The workpiece is in a completely fixed state. When milling and turning of the cylindrical part 51 and drilling of the square skirt 52 are performed using turning tools, when the tool generates a downward drilling force during the drilling process, this force is transmitted to the T-shaped part 31 through the square skirt 52, which in turn pushes the guide rod 33 to slide downward along the cover plate 22 and the through groove 12. The guide rod 33 drives the pressure plate 231 to move downward synchronously, compressing the spring 232. The elastic deformation of the spring 232 absorbs most of the downward impact force, preventing bending deformation of the square skirt 52 due to excessive local force at the opening. The centering clamping of the cylindrical part 51 by the V-shaped part 32 and the limiting support of the square skirt 52 by the T-shaped part 31 effectively limit the cantilever vibration of the cylindrical part 51, ensuring that the workpiece has no displacement or shaking during the processing.
