Description

Technical Field

[0001] This invention relates to the field of tapping device technology, specifically a tapping device for processing terminal blocks. Background Technology

[0002] Tapping is a key process in terminal block manufacturing. It is mainly used to machine internal threaded holes in metal parts to achieve mechanical fixation or electrical connection. As the core component of electrical connection, the machining quality of the internal thread of the terminal block directly affects the conductivity, mechanical strength and installation reliability. The internal thread of the terminal block must match the screw-type clamping frame or mounting screw. The thread profile, pitch, effective length and other parameters must strictly meet the standards to ensure uniform contact pressure distribution and fixing strength.

[0003] In the prior art, such as the nut internal thread tapping mechanism disclosed in CN213794631U, there is a base, a frame mounted on the base, two-axis cylinders, a material feeding cylinder, a tapping device, a feeding turntable, a stripping cylinder, a feeding track, and a discharge track. The cylinder bodies of the two-axis cylinders are fixed above the frame, and the piston rods of the two-axis cylinders are horizontally arranged and connected to the cylinder bodies of the material feeding cylinders. The piston rod of the material feeding cylinder is vertically downward. The two-axis cylinders drive the material feeding cylinder to move back and forth between the feeding track and the feeding turntable to remove the nut to be processed from the feeding track and place it on the feeding turntable. The tapping tool of the tapping device is vertically downward to perform internal thread processing on the nut to be processed, and the tapping device can move up and down. The stripping cylinder is located near the discharge track. The above document is applicable to the automated processing of nut internal thread tapping, replacing the traditional manual mode, thereby improving processing efficiency.

[0004] Although the aforementioned document adopts automated processing methods to improve processing efficiency, in the actual tapping process, the feed turntable not only transports a single workpiece, but also multiple workpieces to be processed on the feed turntable before reaching the tapping position. Traditional equipment only clamps the workpieces to be tapped to maintain stability, while the workpieces waiting to be processed and those that have been processed will vibrate during the tapping process because they are not clamped, causing the turntable to be unstable and prone to skew, affecting the tapping effect. In addition, traditional tapping feed turntables lack cleaning functions, resulting in the accumulation of tapping debris, which affects the tapping quality.

[0005] Therefore, this invention proposes a tapping device for terminal block processing to solve the problems of existing tapping equipment having a simple feeding turntable structure, making it difficult to maintain structural stability during tapping and lacking a tapping debris cleaning function.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Example 1, please refer to Figure 1-17This invention provides a technical solution: a tapping device for processing terminal blocks, comprising an automatic tapping machine body 1, a tapping table 11 fixedly installed on the upper end of the automatic tapping machine body 1, a feeding groove plate 3 and a feeding guide plate 4 respectively provided on both sides of the tapping table 11, a feed inlet and a feed outlet respectively opened on both sides of the tapping table 11, the feeding groove plate 3 fixedly installed on the inner side of the feed outlet, and the side view cross section of the feeding groove plate 3 is an "L" shaped structure, an electric telescopic rod 31 fixedly installed on the end of the feeding groove plate 3 away from the feed outlet, and a feeding push plate fixedly connected to the output end of the electric telescopic rod 31; under the pushing action of the electric telescopic rod 31, the terminal blocks placed on the inner side of the feeding groove plate 3 are tapped. The wire terminal parts are fed in an orderly manner; a tapping unit 12 is provided at the upper end of the tapping table 11, and a feeding turntable mechanism 2 and a workpiece fixing mechanism are provided on the upper surface of the tapping table 11. The workpiece fixing mechanism is located on one side of the feeding turntable mechanism 2 and includes a guide arc plate 25 and a limiting frame 26. A limiting abutment 261 is slidably connected to the inner side of the limiting frame 26. The feeding turntable mechanism 2 includes a fixed seat 21, a connecting plate 22 and a clamping plate 23. The fixed seat 21 is fixedly installed on the upper surface of the automatic tapping machine body 1. A drive assembly 211 is provided at the upper end of the fixed seat 21. The drive assembly 211 consists of a drive motor and a drive shaft. The connecting plate 22 is rotatably installed. The upper surface of the fixed base 21 and the lower surface of the clamping plate 23 are fixedly connected to the upper surface of the connecting plate 22; a material placement groove 230 is provided on the outer ring surface of the clamping plate 23, and a lateral abutment component is provided on the inner side of the material placement groove 230; the lateral abutment component includes a movable abutment plate 2301, which is rotatably mounted on the inner walls of both sides of the material placement groove 230 via a pin, and an elastic block 2302 and a triangular abutment piece 2303 are fixedly connected to the inner side of the movable abutment plate 2301 away from the buffer cavity 2300, and the other end of the elastic block 2302 is fixedly connected to the inner surface of the triangular abutment piece 2303; and a buffer cavity is provided through one side of the material placement groove 230. 2300, the inner side of the buffer cavity 2300 is provided with an end abutment assembly, the end abutment assembly includes an abutment rod 231 and an abutment spring 232, the abutment rod 231 is composed of an abutment plate 2311 and an abutment rod 2312, the end of the abutment rod 2312 away from the abutment plate 2311 is fixedly connected to a connecting vertical rod 233, the lower end of the connecting vertical rod 233 is fixedly connected to a push rod 234, the push rod 234 passes through the lower inner wall of the sleeve ring 24 and the inner surface of the connecting plate 22 and is slidably connected thereto, the end of the push rod 234 away from the connecting vertical rod 233 is fixedly connected to a pusher block 235, the pusher block 235 is slidably installed on the inner side of the storage frame 221;

[0039] In this embodiment, when the terminal block to be machined is being threaded, the workpiece moves forward under the pushing action of the electric telescopic rod 31. During this process, the drive motor drives the drive shaft to rotate, keeping the connecting plate 22 and the clamping plate 23 rotating at a certain speed. (Refer to...) Figure 3As shown, the terminal block processing part enters the material placement groove 230 at the outlet end of the loading groove plate 3. When the workpiece to be processed reaches the position directly below the tapping unit 12, the control limit plate 261 pushes to one side of the workpiece to hold one end of the terminal block processing part. At this time, the other end of the terminal block processing part holds the inner holding rod 231, and the abutment spring 232 is compressed. Then the tapping operation is performed. After the tapping is completed, the workpiece continues to rotate. When the workpiece is released from the inner holding of the guide arc plate 25, the workpiece reaches the upper end of the unloading guide plate 4. At this time, the holding rod 231 pushes the workpiece outward, so that the processed terminal block processing part is unloaded with the unloading guide plate 4.

[0040] It should be noted that when the terminal block enters the inner side of the feeding trough 230, its side abuts against the triangular abutment 2303, and the movable abutment plates 2301 on both sides swing at an angle, self-clamping the side of the terminal block processing part. At the same time, the end of the terminal block processing part abuts against the abutment plate 2311. Through the cooperation of the abutment rod 231 and the abutment spring 232, the processing part can be buffered, avoiding the clamping plate 23 from being directly impacted by the pushing terminal, thus extending the service life of the equipment. It is worth noting that, referring to Figure 5 As shown, this state represents the pushing effect of the abutment rod 231 under force, as... Figure 6 As shown, this state is the effect of the holding rod 231 pushing out of the buffer cavity 2300 and pushing the workpiece. When the holding rod 231 is pushed inward by external force, the connecting vertical rod 233 connected to the end of the holding rod 231 away from the contact plate 2311 drives the pushing rod 234 to move inward. At this time, the pusher block 235 slides to the inside of the storage frame 221. Conversely, when the pusher block 235 moves outward, the pusher block 235 can automatically push out the tapping impurities accumulated inside the storage frame 221.

[0041] Example 2, see attached document Figure 1-17 Based on Example 1, in order to achieve the collection of tapping debris and tapping coolant:

[0042] The inner wall of the outer ring of the connecting plate 22 is provided with mounting grooves 220. A storage frame 221 is movably embedded in the inner surface of the mounting groove 220. A movable sealing plate 222 is movably connected to one end of the outer side of the storage frame 221. An electromagnet is fixedly installed on the outer surface of the movable sealing plate 222. A pin is fixedly connected to the inner wall of the lower end of the movable sealing plate 222. The two ends of the pin are rotatably connected to the inner wall of the storage frame 221, and torsion springs are sleeved on both ends of the pin. Through the cooperation of the pin and the torsion springs, the movable sealing plate 222 can be automatically reset after losing its magnetism, thereby realizing the automatic sealing of the storage frame 221.

[0043] In this embodiment, the connecting plate 22 is rotatably mounted on the upper side of the fixed base 21, and corresponding mounting slots 220 are opened at the corresponding positions of the connecting plate 22 and the material storage groove 230, and storage frames 221 are installed one by one. The storage frames 221 can temporarily store the debris generated by tapping. It should be noted that the diameter of the mounting slot 220 is smaller than the diameter of the material storage groove 230. When the terminal block is processed into the inner side of the material storage groove 230, the top of the storage frame 221 can support the bottom of the workpiece. It is also worth noting that an electromagnet is installed on the outer side of the movable sealing plate 222, and the unloading guide plate 4 is close to the clamp. A matching electromagnet is installed on one side of the material tray 23. When a set of impurity storage boxes 221 arrives at the position of the feeding guide plate 4, electromagnets 1 and 2 are energized. At this time, electromagnet 1 will drive the movable sealing plate 222 to move closer to the feeding guide plate 4, thus realizing the automatic opening of the movable sealing plate 222. At this time, the terminal processing parts are also pushed out by the abutment rod 231, and at this time, the impurity pushing inclined block 235 is pushed outward at the same time to push out the impurities accumulated inside the impurity storage box 221. This satisfies the unloading of the workpiece, the automatic opening and closing of the movable sealing plate 222, and the self-cleaning of impurities.

[0044] Example 3, refer to Appendix Figure 1-17 Based on Example 2, in order to achieve stability during the feeding of the terminal block processing parts:

[0045] The limiting frame 26 is fixedly installed on the inner side of the back end of the tapping table 11. The guide arc plate 25 is fixedly installed on the upper surface of the tapping table 11 by bolts. The inner wall of the guide arc plate 25 away from the limiting frame 26 is provided with a central square groove 250 and an arc-shaped receiving groove 2500. A connecting groove is provided between the central square groove 250 and the arc-shaped receiving groove 2500. A shock-absorbing clamping assembly is provided on the inner side of the guide arc plate 25. The shock-absorbing clamping assembly includes a connecting wing plate 2611. Two sets of connecting wing plates 2611 are provided and are mirrored about the central axis of the limiting plate 261. The connecting wing plates 2611 are fixedly installed on both sides of the limiting plate 261. A linkage gear 2612 is meshed and rotated on the outer surface of the connecting wing plate 2611. A swinging rod 2613 is meshed and rotated on the other side of the linkage gear 2612. The swinging rod 2613 is composed of a half gear and a bent plate. The outer surface of the bent plate is respectively connected to the connecting plate 22 and the clamping plate. The outer surface of the disc 23 movably abuts against the surface; an elastic support is provided between the inner side of the swinging rod 2613 and the arc-shaped storage groove 2500. The elastic support includes an arc-shaped support rod 2614, a sliding collar 2615, and an abutting rod 2617. One end of the arc-shaped support rod 2614 is fixedly connected to the inner wall of the arc-shaped storage groove 2500, and the other end of the arc-shaped support rod 2614 is fixedly connected to the inner curved surface of the swinging rod 2613. The sliding collar 2615 slides smoothly. Installed on the outer surface of the arc-shaped support rod 2614, one end of the sliding collar 2615 is fixedly connected to the sleeve spring wire 2616, the sleeve spring wire 2616 is slidably sleeved on the outside of the arc-shaped support rod 2614, and the other end of the sleeve spring wire 2616 is fixedly connected to the outer surface of the bent plate. The outer side of the sliding collar 2615 is rotatably connected to one end of the abutment rod 2617, and the other end of the abutment rod 2617 is movably connected to the inner surface of the arc-shaped storage groove 2500.

[0046] In this embodiment, when the driving limiting plate 261 moves towards the clamping plate 23, one outer end of the limiting plate 261 supports the workpiece below the forward tapping unit 12. At the same time, the workpieces distributed on both sides of the tapping workpiece are simultaneously supported to avoid vibration. Specifically, refer to... Figures 12-13 As shown, when the limiting plate 261 is pushed towards one side of the workpiece, the connecting wing plates 2611 on both sides move synchronously, so that the linkage gears 2612 on both sides mesh. At this time, the linkage gears 2612 rotate clockwise, and the swing arm 2613 rotates counterclockwise, so that the swing arm 2613 synchronously supports the workpieces distributed on both sides of the tapping workpiece, avoiding vibration or displacement. It is worth noting that the setting of the elastic support provides dynamic compensation for the clamping action of the swing arm 2613 and can provide strength support for the swing arm 2613, so that the swing arm 2613 can stably support the workpiece during the tapping operation, further improving the tapping effect of the workpiece.

[0047] Example 4, see attached document Figure 1-17 Based on Example 3, in order to achieve rapid unloading and auxiliary cleaning of the terminal block processing parts:

[0048] A sleeve ring 24 is fixedly connected to the inner center of the clamping disc 23. The sleeve ring 24 penetrates the inner center wall of the clamping disc 23 and the connecting disc 22 and is fixedly connected to the outer surface of the drive shaft. A pressure boosting pipe 241 is installed through the upper inner wall of the sleeve ring 24. The outlet end of the pressure boosting pipe 241 extends to the inner side of the buffer chamber 2300. A pressure boosting pump is connected to the input end of the pressure boosting pipe 241. The pressure boosting pump is installed on the upper surface of the sleeve ring 24. The outer surface of the contact rod 2312 penetrates the clamping disc 23. 3. The inner wall of the sleeve ring 24 extends into the interior of the sleeve ring 24. The abutment spring 232 is slidably sleeved on the outside of the abutment rod 2312. One end of the abutment spring 232 is fixedly connected to the inner side of the abutment plate 2311, and the other end of the abutment spring 232 is fixedly connected to the inner side wall of the buffer cavity 2300. A pressure-increasing groove 23110 is provided on the inner wall of the abutment plate 2311 near the abutment rod 2312. A sealing bolt 2 is slidably connected to the inner surface of the pressure-increasing groove 23110. 3111, the sealing bolt 23111 has a "T"-shaped block structure. A compression block 23112 is fixedly connected to the inner side of the sealing bolt 23111. The other end of the compression block 23112 is fixedly connected to the inner side wall of the pressure-boosting groove 23110. An air-guiding support groove 23120 and an air-guiding center groove 23121 are respectively opened on the inner wall of the contact rod 2312. The air-guiding center groove 23121 is located on the central inner wall of the contact rod 2312 and passes through the center of the contact plate 2311, guiding air... The support groove 23120 has four sets arranged in an array about the central axis of the abutment rod 2312. One end of the air guide support groove 23120 is connected to the air guide support groove 23120, and the other end of the air guide support groove 23120 is connected to one end of the air guide center groove 23121. The output end of the air guide center groove 23121 is provided with a conical groove, which is opened on the central inner wall of the abutment plate 2311, and the inner surface of the conical groove is threaded with a threaded conical cover 2313.

[0049] In this embodiment, when the tapped terminal block reaches above the unloading guide plate 4, the pressurization pipe 241 is opened to introduce pressurized gas into the buffer chamber 2300. (Refer to...) Figure 6As shown, when pressurized gas is continuously supplied to the inner cavity of the buffer chamber 2300, the abutment plate 2311 is pushed outward by the pressurized gas, pushing the workpiece inside the material tray 230 to unload the workpiece. At the same time, the abutment spring 232 is elastically stretched, and the connecting vertical rod 233 moves. When the connecting vertical rod 233 moves to fit against the inner side wall of the sleeve ring 24, the abutment plate 2311 reaches the end of the buffer chamber 2300, and the buffer chamber 2300 is always in a closed state. Under the continuous injection of pressurized gas, the sealing bolt 23111 inside the pressurization groove 23110 is pushed inward by the gas. The gas is pushed and compressed by the extrusion block 23112. At this time, the gas opens the channel between the gas guide groove 23120 and the pressurization groove 23110. The gas enters the gas guide groove 23120 and is discharged to the conical groove through the gas guide center groove 23121. Finally, it is sprayed outward through the threaded cone cover 2313 on the inner side of the center of the contact plate 2311. This achieves self-cleaning of residual impurities on the material storage tank 230. The threaded cone cover 2313 is a flared cone structure with a narrow inner and wide outer opening, which facilitates the diffusion of airflow. It is connected to the contact plate 2311 in a detachable threaded manner, which facilitates quick replacement after wear and tear during long-term use.

[0050] The working principle and usage process of this invention are as follows: In actual use, firstly, when the terminal block to be processed is being threaded and tapped, the workpiece moves forward under the pushing action of the electric telescopic rod 31. The terminal block enters the material placement groove 230 aligned with the outlet end of the loading groove plate 3, and its side abuts against the triangular abutment 2303. The movable abutment plates 2301 on both sides swing at an angle, self-clamping the side of the terminal block. When the workpiece to be processed reaches the position directly below the tapping unit 12, the control limit abutment plate 261 is pushed towards one side of the workpiece, and the other end of the terminal block abuts against the inner abutment rod 231. At this time, the workpiece is clamped from multiple sides. At the same time, the drive limit abutment plate 261 is pushed towards one side of the clamping plate 23. The outer end of the moving and limiting stop plate 261 abuts against the workpiece below the forward tapping unit 12, and the workpieces distributed on both sides of the tapping workpiece abut simultaneously; furthermore, when a certain set of storage boxes 221 reaches the position of the unloading guide plate 4, electromagnet one and electromagnet two are energized. At this time, electromagnet one will drive the movable sealing plate 222 to move closer to the side of the unloading guide plate 4, and the movable sealing plate 222 will automatically open; finally, the control pressure pipe 241 is opened, and pressurized gas is introduced into the buffer chamber 2300. The pressurized gas is continuously supplied into the buffer chamber 2300, and the abutment plate 2311 is pushed outward by the pressurized gas, pushing the workpiece inside the material slot 230, and finally realizing the unloading of the workpiece. The above steps are repeated to continuously perform the tapping operation of the terminal processing workpiece.
