Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal housing insertion machine technology, and in particular to a terminal housing positioning mechanism, which is mainly used in automated production lines to accurately position and fix terminal housings made of plastic material, so as to ensure that the terminal wires can be accurately inserted into the housings. Background Technology
[0002] Currently, terminal inserting machines on the market typically insert the casing after the pusher mechanism has positioned it, relying on an elastic mechanism for positioning. However, since the casing is made of plastic, its dimensions have a certain degree of error, which means the elastic mechanism cannot guarantee absolute accuracy during positioning. Furthermore, vibrations generated during equipment operation may cause changes in the angle of the casing, affecting the insertion of the terminal wire and leading to insertion failure. Utility Model Content
[0003] In view of the above problems, this utility model proposes a terminal housing positioning mechanism, which aims to solve the problem of inaccurate positioning caused by housing material errors and equipment vibration, thereby improving the accuracy and reliability of terminal wire insertion into the housing.
[0004] The technical solution adopted by this utility model to achieve the above objectives is: a terminal housing positioning mechanism, comprising:
[0005] Base;
[0006] The housing clamping auxiliary part includes a mounting frame pivotally connected to the base and a contour positioning plate slidably mounted on the mounting frame. The front end of the contour positioning plate is provided with a contour groove with the same shape as the housing. It also includes a housing pressure plate that cooperates with the contour positioning plate to clamp the housing. The upper end of the housing pressure plate is provided with a mounting plate. The mounting plate is provided with several ball screws corresponding to the position of the contour groove. The ball screws pass through the housing pressure plate, so that when the housing pressure plate is clamped with the contour positioning plate, the ball end of the ball screw fixes the housing in the contour groove. The mounting frame is provided with a first cylinder that drives the contour positioning plate to move back and forth. The mounting frame is also provided with a second cylinder that drives the housing pressure plate to move up and down.
[0007] An assembly angle auxiliary part is provided on the base and is used to push the plastic shell held on the plastic shell clamping auxiliary part to adjust to the pre-insertion angle. It includes an adjustment frame on the base and a third cylinder pivotally connected to the adjustment frame. The mounting frame is pivotally connected to the adjustment frame, and the output end of the third cylinder is hinged to the mounting frame through a rotating shaft.
[0008] The process involves the first cylinder pushing the contour positioning plate to insert the rubber shell into the contour groove, the second cylinder pushing the rubber shell pressure plate downward to clamp the rubber shell with the contour positioning plate, the ball end of the ball screw fixing the rubber shell in the contour groove, and the third cylinder pushing the mounting bracket to adjust the clamped rubber shell to the pre-insertion angle.
[0009] As a further improvement, the housing clamping auxiliary part also includes a guide plate, which is horizontally fixed to the lower end of the mounting bracket. The guide plate is provided with a slide groove, in which the contour positioning plate slides. The guide plate is also provided with a pressure strip to prevent the contour positioning plate from falling out of the slide groove. The front end of the guide plate is provided with a front step, which is used to block the housing from being pushed forward.
[0010] As a further improvement, the housing clamping auxiliary part also includes a connecting block and a vertical slide rail. The vertical slide rail is mounted on the mounting bracket, and the connecting block is equipped with a slider that slides with the vertical slide rail. The output end of the second cylinder is connected to the connecting block, the housing pressure plate is fixedly connected to the connecting block, and the bottom of the connecting block has an opening to avoid the pressure bar.
[0011] As a further improvement, the mounting bracket is provided with a first rotating shaft, which is fixed to the adjusting bracket, and first bearings that rotate with the mounting bracket are installed at both ends of the first rotating shaft.
[0012] As a further improvement, the base is provided with a first adjustment mounting position, and the adjustment frame is provided with a second adjustment mounting position corresponding to the first adjustment mounting position.
[0013] As a further improvement, a mounting block is provided at the bottom of the third cylinder, and a second rotating shaft is provided on the mounting block. The two ends of the second rotating shaft are provided with second bearings that are connected to the adjusting bracket.
[0014] As a further improvement, the output end of the third cylinder is equipped with a fisheye connector, and the shaft is connected to the fisheye connector.
[0015] As a further improvement, the housing pressure plate is provided with a third adjustment mounting position, and the mounting plate is provided with a fourth adjustment mounting position corresponding to the third adjustment mounting position.
[0016] As a further improvement, the housing pressure plate is provided with a movable opening corresponding to the position of the ball screw.
[0017] The beneficial effects of this utility model are as follows: A first cylinder pushes the contour positioning plate, causing the rubber shell to insert into the contour groove. A second cylinder pushes the rubber shell pressure plate downwards, clamping the rubber shell with the contour positioning plate. The ball end of the ball screw fixes the rubber shell in the contour groove. A third cylinder pushes the mounting bracket, adjusting the clamped rubber shell to a pre-insertion angle. After the rubber shell angle is adjusted to the mounting position, the pre-insertion of the terminal wire is performed. After pre-insertion, the third cylinder resets, straightening the rubber shell for the final insertion. Finally, the second cylinder drives the rubber shell pressure plate to rise, and then the pressure plate resets, releasing the rubber shell with the inserted terminal. This utility model achieves a process where the rubber shell is first pushed into position, then pushed out and positioned, followed by a second contour positioning, ensuring precise positioning to meet the terminal wire insertion requirements. Pre-insertion at an angle is possible, and the shell can be fully inserted after returning to the original angle, ensuring the quality of the inserted shell. This utility model ensures that the rubber shell is accurately positioned and fixed before the terminal wire is inserted, thereby improving the success rate of insertion and production efficiency.

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0023] Please see Figure 1 and Figure 2 This embodiment provides a terminal housing positioning mechanism, which includes a base 10, a housing clamping auxiliary part 20, and an assembly angle auxiliary part 30.
[0024] Please see Figure 3The housing clamping auxiliary part 20 is mainly used for positioning the housing. In this embodiment, the main structure of the housing clamping auxiliary part 20 is as follows: the housing clamping auxiliary part 20 includes a mounting frame 201, a guide plate 202 is horizontally mounted on the lower end of the mounting frame 201, the guide plate 202 is provided with a sliding groove, a contour positioning plate 203 is slidably mounted in the sliding groove, and a pressure strip 204 is provided on the guide plate 202. The sliding groove and pressure strip 204 can ensure the stability of the contour positioning plate 203 during operation and prevent it from falling out of the sliding groove. The front end of the guide plate 202 is provided with a front step 206, which is used to block the housing from pushing forward; the front end of the contour positioning plate 203 is provided with several contour grooves 205 that are the same shape as the housing. The contour grooves 205 of the contour positioning plate 203 are designed to completely match the shape of the housing to ensure the accuracy of the housing during positioning; the mounting frame 201 is horizontally mounted on the lower end of the mounting frame 201. The guide plate 202 is provided with a sliding groove, a guide plate 202 is horizontally mounted on the lower end of the mounting frame 201 ... 1. A vertical slide rail is installed, and a slider is slidably mounted on the vertical slide rail. A connecting block 207 is installed on the slider. The bottom of the connecting block 207 has an opening to avoid the pressure strip 204. The connecting block 207 has a rubber shell pressure plate 208 that cooperates with the contour positioning plate 203 to clamp the rubber shell. The upper end of the rubber shell pressure plate 208 has a mounting plate 209. The mounting plate 209 has several ball screws that correspond to the position of the contour groove 205. The ball screws pass through the rubber shell pressure plate 208, so that when the rubber shell pressure plate 208 is clamped with the contour positioning plate 203, the ball end of the ball screw fixes the rubber shell in the contour groove 205. The mounting frame 201 has a first cylinder 210 that drives the contour positioning plate 203 to move back and forth. The mounting frame 201 also has a second cylinder 211 that drives the rubber shell pressure plate 208 to move up and down. The output end of the second cylinder 211 is connected to the connecting block 207.
[0025] As described above, when the device pushes the rubber shell to the front step 206, the front step 206 blocks the rubber shell from being pushed forward. At this time, the first cylinder 210 pushes the contour positioning plate 203 to move towards the rubber shell, so that the rubber shell is inserted into the contour groove 205. After the rubber shell is inserted into the contour groove 205, the second cylinder 211 pushes the rubber shell pressure plate 208 down, so that the rubber shell pressure plate 208 and the contour positioning plate 203 clamp the rubber shell, and the ball end of the ball screw fixes the rubber shell in the contour groove 205 to prevent the rubber shell from moving, thereby achieving the positioning of the rubber shell.
[0026] Please see Figure 4The assembly angle auxiliary part 30 is mainly used to push the plastic shell held on the plastic shell clamping auxiliary part 20 to adjust to the pre-insertion angle. In this embodiment, the main structure of the assembly angle auxiliary part 30 is as follows: the assembly angle auxiliary part 30 includes an adjustment frame 301 provided on the base 10 and a third cylinder 302 pivotally connected to the adjustment frame 301. The output end of the third cylinder 302 is provided with a fisheye connector 303. A rotating shaft is installed on the fisheye connector 303. The rotating shaft is connected to the mounting frame 201. The bottom of the third cylinder 302 is provided with a mounting block 304. The mounting block 304 is provided with a second rotating shaft. The two ends of the second rotating shaft are provided with second bearings connected to the adjustment frame 301.
[0027] To enable the housing clamping auxiliary part 20 to be pushed by the third cylinder 302, a first rotating shaft is provided on the mounting frame 201. The first rotating shaft is fixed to the adjusting frame 301, and first bearings that rotate with the mounting frame 201 are installed at both ends of the first rotating shaft. This allows the mounting frame 201 to be pushed by the third cylinder 302, thereby adjusting the clamped housing to the pre-insertion angle. The design of the rotating shaft and bearings on the mounting frame 201 ensures the flexibility and durability of the mechanism during operation. The arrangement of the first and second rotating shafts allows the mounting frame 201 and the adjusting frame 301 to rotate smoothly and without obstruction during operation.
[0028] In an optional embodiment, the base 10 is provided with a first adjustment mounting position 101, and the adjustment frame 301 is provided with a second adjustment mounting position corresponding to the first adjustment mounting position 101. By setting the first adjustment mounting position 101 and the second adjustment mounting position, the position of the assembly angle auxiliary part 30 can be adjusted according to the needs of different products. In this embodiment, the first adjustment mounting position 101 is set as a strip-shaped countersunk hole, and the second adjustment mounting position is set as a threaded hole. The adjustment frame 301 is fixed to the base 10 by bolts, and the position of the assembly angle auxiliary part 30 is adjusted by loosening the bolts.
[0029] In an optional embodiment, the housing pressure plate 208 is provided with a third adjustment mounting position, and the mounting plate 209 is provided with a fourth adjustment mounting position corresponding to the third adjustment mounting position. The housing pressure plate 208 is also provided with a movable opening corresponding to the position of the ball screw. The design of the adjustment mounting position and the movable opening on the housing pressure plate 208 can further improve the adaptability and ease of operation of the mechanism. In this embodiment, the third adjustment mounting position is set as a strip groove, and the fourth adjustment mounting position is set as a threaded hole.
[0030] In summary, the working principle of this terminal housing positioning mechanism is as follows: When the equipment pushes the housing to the front step 206, the front step 206 blocks the housing from being pushed forward. At this time, the first cylinder 210 pushes the contour positioning plate 203 towards the housing, causing the housing to insert into the contour groove 205. After the housing is inserted into the contour groove 205, the second cylinder 211 pushes the housing pressure plate 208 downward, causing the housing pressure plate 208 and the contour positioning plate 203 to clamp the housing. The housing is then secured by the ball screw. The bead end fixes the rubber shell within the contour groove 205 to prevent movement. After the rubber shell is positioned, the third cylinder 302 pushes the mounting bracket 201, adjusting the clamped rubber shell to a pre-insertion angle. After the rubber shell angle is adjusted to the mounting position, the pre-insertion of the terminal wire is performed. After pre-insertion, the third cylinder 302 resets to straighten the rubber shell for the final insertion. Finally, the second cylinder 211 drives the rubber shell pressure plate 208 to lift, and then the rubber shell pressure plate 208 resets, releasing the rubber shell with the inserted terminal. This utility model achieves the rubber shell being pushed into position first, then pushed out and positioned, followed by a secondary contour positioning to ensure accurate positioning to meet the terminal wire insertion requirements. The shell can be pre-inserted at an angle, and then fully inserted after returning to the original angle, achieving precise positioning and stable clamping of the rubber shell, thus significantly improving the efficiency and quality of terminal insertion.
