Description

Technical Field

[0001] This utility model belongs to the field of crimping machine technology, and specifically relates to a terminal crimping machine. Background Technology

[0002] Utility model patent CN210779435U discloses a terminal crimping machine, including a crimping machine body. A controller body is mounted on the upper right side of the crimping machine body via screws, and a metal shaping tube is connected to the bottom of the controller body. A lighting lamp electrically connected to the controller body is installed at the end of the metal shaping tube. A bracket is mounted on the bottom right side of the crimping machine body via screws, and a display panel electrically connected to the controller body is mounted on the upper end of the bracket via screws. A servo motor is mounted on the upper part of the crimping machine body, which drives a ball screw pair to rotate, thereby driving the ball screw nut pair to move up and down, and in turn driving the mold mechanism to move up and down and pass through the through hole. At the same time, the matching of the slide rod and slide rail can increase the stability of the mold chuck movement, so that the mold chuck can stably press the upper end of the mold body. However, when using this device, the terminal crimping efficiency is low. In addition, during the terminal crimping process, the wire harness lacks a limit, which makes the wire harness and the terminal easy to loosen during the crimping process. Summary of the Invention

[0003] The purpose of this utility model is to provide a terminal crimping machine that solves the problem of low terminal crimping efficiency in existing terminal crimping machines. In addition, the lack of limiting of the wire harness during the terminal crimping process makes the wire harness and terminal easy to loosen during the crimping process.

[0004] To achieve the above objectives, this utility model provides a terminal crimping machine, including a base plate, a conversion mechanism on the base plate, a turntable on the conversion mechanism, a placement groove on the turntable, a clamping mechanism at the upper end of the turntable, a bracket welded to the upper end of the base plate, a cylinder fixedly mounted at the middle of the upper end of the bracket, the cylinder rod of the cylinder passing through the bracket and slidably connected to the bracket, and a pressure block welded to the lower end of the cylinder rod.

[0005] The principle of this utility model is as follows: In use, the terminal is placed in the deep groove of the placement slot, the wire harness is inserted into the terminal, and then the limiting block is manually moved upwards, compressing the spring and placing the wire harness in the shallow groove of the placement slot. Then, the limiting block is released, the spring returns to its original position, and the limiting block is pressed downwards, thus pressing the wire harness firmly within the placement slot. The spring acting on the limiting block limits the wire harness within the placement slot, preventing movement of the wire harness during the crimping process with the terminal, ensuring a stable connection between the terminal and the wire harness after crimping. Then, the cylinder... The cylinder rod extends, causing the pressure block to move downwards, thus pressing the terminal together. The motor is then started, driving the turntable to rotate. The rotation of the turntable changes the position of the placement slot, causing the placement slot to rotate and change its position. Simultaneously, the insert block and the slot are misaligned, allowing the insert block to enter the slide cylinder, which compresses the spring until the insert block slides to the next slot. The spring acts on the insert block, causing it to engage with the slot, thus facilitating the turntable's positioning. This allows the device to change terminals without stopping the machine, resulting in higher terminal crimping efficiency.

[0006] The beneficial effects of this utility model are as follows: the turntable is driven by a motor to rotate, thereby causing the placement slot to rotate and change positions. The spring acts on the insertion block, so that the insertion block and the slot cooperate, thereby making the turntable easy to limit the position. This allows the device to replace terminals without stopping the machine, and thus makes the device more efficient at crimping terminals.

[0007] The compression spring acts on the limiting block to limit the wire harness placed in the placement slot, thereby preventing the wire harness from moving during the crimping process with the terminal and ensuring a stable connection between the terminal and the wire harness after crimping.

[0008] Furthermore, the conversion mechanism includes a motor, a slide cylinder, a plug, a spring, a slot, and a support ring. A motor is fixedly installed at the lower center of the base plate. The output end of the motor passes through the base plate and is rotatably connected to it. The output end is welded to a turntable. A slide cylinder is welded to the lower end of the turntable. A plug is slidably connected inside the slide cylinder, and a spring is installed inside the slide cylinder. A slot is provided at the upper end of the base plate, and the slot is slidably connected to the plug. The motor drives the turntable to rotate, thereby causing the placement slot to rotate and change positions. The spring acts on the plug, causing the plug and slot to engage, facilitating the turntable's positioning. This allows for terminal replacement without stopping the device, resulting in higher terminal crimping efficiency.

[0009] Furthermore, one end of the spring is welded to the turntable, and the other end of the spring is welded to the insert block. The spring acts on the insert block, making it easy for the insert block to reset.

[0010] Furthermore, a support ring is welded to the upper end of the base plate, and the support ring contacts the turntable. The support ring provides auxiliary support to the turntable.

[0011] Furthermore, the clamping mechanism includes a column, a support plate, a square rod, a stop block, a limiting block, and a compression spring. A column is welded to the upper end of the turntable, and a support plate is welded to the upper edge of the column. A square rod is slidably connected inside the support plate, and a limiting block is welded to the lower end of the square rod. The limiting block contacts the turntable, and a compression spring is provided on the outer side of the square rod. The compression spring acts on the limiting block, limiting the wire harness placed in the placement slot, thereby preventing movement of the wire harness during the crimping process with the terminal and ensuring a stable connection between the terminal and the wire harness after crimping.

[0012] Furthermore, a stop block is welded to the upper end of the square rod, and the stop block contacts the support plate. By setting the stop block, the square rod is limited.

[0013] Furthermore, one end of the compression spring is welded to the support plate, and the other end of the compression spring contacts the limiting block. By providing the compression spring, the Shudie limiting block can be easily reset. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the conversion mechanism 2 includes a motor 21, a slide cylinder 22, a plug block 23, a spring 24, a slot 25, and a support ring 26. The motor 21 is fixedly installed at the lower center of the base plate 1. The output end of the motor 21 passes through the base plate 1 and is rotatably connected to it. The output end is welded to the turntable 3. The lower end of the turntable 3 is welded to the slide cylinder 22. The plug block 23 is slidably connected inside the slide cylinder 22. A spring 24 is installed inside the slide cylinder 22. One end of the spring 24 is welded to the turntable 3, and the other end is welded to the plug block 23. The spring 24 acts on the plug block 23, causing... The insertion block 23 is easy to reset. The upper end of the base plate 1 is provided with a slot 25, which is slidably connected to the insertion block 23. The upper end of the base plate 1 is welded with a support ring 26, which is in contact with the turntable 3. By setting the support ring 26, the turntable 3 is provided with auxiliary support. The turntable 3 is driven to rotate by the motor 21, which causes the placement slot 4 to rotate and change positions. The spring 24 acts on the insertion block 23, which makes the insertion block 23 and the slot 25 cooperate, thus making the turntable 3 easy to limit. This allows the device to change terminals without stopping the machine, and thus makes the device more efficient at crimping terminals.

[0022] like Figure 1 , Figure 2 , Figure 4 As shown, the clamping mechanism 5 includes a column 51, a support plate 52, a square rod 53, a stop block 54, a limiting block 55, and a compression spring 56. The column 51 is welded to the upper end of the turntable 3. The support plate 52 is welded to the upper edge of the column 51. The square rod 53 is slidably connected inside the support plate 52. The stop block 54 is welded to the upper end of the square rod 53, and it contacts the support plate 52. By setting the stop block 54, the square rod 53 is limited. The limiting block 56 is welded to the lower end of the square rod 53. 5. The limiting block 55 contacts the turntable 3. A compression spring 56 is provided on the outside of the square rod 53. One end of the compression spring 56 is welded to the support plate 52, and the other end of the compression spring 56 contacts the limiting block 55. By setting the compression spring 56, the limiting block 55 can be easily reset. The compression spring 56 acts on the limiting block 55, so that the wire harness placed in the placement slot 4 is limited, thereby preventing the wire harness from moving during the crimping process of the wire harness and the terminal, and ensuring that the connection between the terminal and the wire harness is stable after crimping.

[0023] The specific implementation process of this utility model is as follows: In use, the terminal is placed in the deep groove of the placement groove 4, and the wire harness is inserted into the terminal. Then, the limiting block 55 is manually moved upward, so that the compression spring 56 is compressed, and the wire harness is placed in the shallow groove of the placement groove 4. Then, the limiting block 55 is released, and the compression spring 56 returns to its original position, so that the limiting block 55 is pressed downward, thereby pressing the wire harness tightly in the placement groove 4. Through the action of the compression spring 56 on the limiting block 55, the wire harness placed in the placement groove 4 is limited, thereby preventing the wire harness from moving during the crimping process between the wire harness and the terminal, ensuring a stable connection between the terminal and the wire harness after crimping. Then, the cylinder 7 drives the cylinder rod to extend. The cylinder rod moves the pressure block 8 downward, thereby pressing the terminal together. The motor 21 is started, and the motor 21 drives the turntable 3 to rotate. The rotation of the turntable 3 causes the position of the placement slot 4 to change, thereby causing the placement slot 4 to rotate and change its position. At the same time, the insertion block 23 and the slot 25 are misaligned, so that the insertion block 23 enters the slide cylinder 22, thereby compressing the spring 24 until the insertion block 23 slides to the next slot 25. The spring 24 acts on the insertion block 23, so that the insertion block 23 and the slot 25 cooperate, thereby making the turntable 3 easy to limit the position, thereby allowing the device to change the terminal without stopping the machine, and thus making the device more efficient in crimping the terminal.

[0024] The turntable 3 is driven to rotate by the motor 21, which in turn causes the placement slot 4 to rotate and change positions. The spring 24 acts on the insertion block 23, which makes the insertion block 23 and the slot 25 cooperate, thus making the turntable 3 easy to limit the position. This allows the device to change terminals without stopping the machine, and makes the device more efficient at crimping terminals.

[0025] The compression spring 56 acts on the limiting block 55, which limits the wire harness placed in the placement groove 4, thereby preventing the wire harness from moving during the crimping process with the terminal and ensuring a stable connection between the terminal and the wire harness after crimping.
