Description

Technical Field

[0001] The invention relates to the technical field of tapping devices, in particular to a tapping device for processing connecting terminals. Background Art

[0002] Tapping is a key process in the processing of terminal blocks. It is mainly used to process internal threaded holes on metal parts to achieve mechanical fixation or electrical connection. As the core component of electrical connection, the processing quality of the internal threads of the terminal holes directly affects the conductive performance, mechanical strength and installation reliability. The internal threads of the terminal holes must match the screw-type wire frame or mounting screws. Parameters such as thread profile, pitch, and effective length must strictly comply with the standards to ensure uniform contact pressure distribution and fixing strength.

[0003] In the prior art, there is a nut internal thread tapping mechanism with publication number CN213794631U, which includes a base, a frame arranged on the base, a two-axis cylinder, a material picking and feeding cylinder, a tapping device, a feeding turntable, a stripping cylinder, a feeding track and a discharging track; the cylinder body of the two-axis cylinder is fixedly arranged above the frame, the piston rod of the two-axis cylinder is arranged horizontally and connected to the cylinder body of the material picking and feeding cylinder, the piston rod of the material picking cylinder is arranged vertically downward, and the two-axis cylinder drives the material picking and 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 arranged vertically downward to perform internal thread processing on the nut to be processed, and the tapping device of the tapping device can move up and down; the stripping cylinder is arranged near the discharging track. The above document is suitable for automated processing of nut internal thread tapping, replacing the traditional manual mode, thereby improving processing efficiency.

[0004] Although the above-mentioned document adopts an automated processing method to improve processing efficiency, during the actual tapping process, the feed turntable not only transports a single workpiece, but there are multiple workpieces to be processed on the feed turntable before it reaches the tapping position. The traditional equipment only clamps the workpiece to be tapped to maintain stability. The workpieces waiting to be processed and completed will vibrate in the tapping state due to not being clamped, resulting in the turntable being unstable and prone to deflection, affecting the tapping effect. In addition, the traditional tapping feed turntable lacks cleaning function, resulting in the accumulation of tapping debris, affecting the tapping quality.

[0005] Therefore, the present invention proposes a tapping device for processing terminal blocks to solve the problems that the feed turntable of existing tapping equipment has a single structure, is difficult to maintain structural stability in the tapping state, and lacks a tapping debris cleaning function.

DETAILED DESCRIPTION

[0021] For example 1, please refer to Figure 1-17The present invention provides a technical solution: a tapping device for processing terminal blocks, comprising an automatic tapping machine body 1, a tapping table 11 is fixedly installed on the upper end of the automatic tapping machine body 1, a feeding trough plate 3 and a feeding guide plate 4 are respectively provided on both sides of the tapping table 11, a feeding port and an inlet are respectively provided on both sides of the tapping table 11, the feeding trough plate 3 is fixedly installed on the inner side of the feeding port, and the side view cross section of the feeding trough plate 3 is an "L"-shaped structure, an electric telescopic rod 31 is fixedly installed on the end of the feeding trough plate 3 away from the feeding port, and the output end of the electric telescopic rod 31 is fixedly connected to a feeding push plate; under the pushing action of the electric telescopic rod 31, the terminal block placed on the inner side of the feeding trough plate 3 is pushed forward. The wire terminal processing parts are loaded 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 arranged on one side of the feeding turntable mechanism 2, and the workpiece fixing mechanism includes a guide arc plate 25 and a limit frame 26. The inner side of the limit frame 26 is slidably connected to the limit plate 261. 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 side surface of the automatic tapping machine body 1. A driving assembly 211 is provided at the upper end of the fixed seat 21. The driving assembly 211 consists of a driving motor and a driving shaft. The connecting plate 22 is rotatably installed On the upper surface of the fixed seat 21, the lower surface of the clamping disc 23 is fixedly connected to the upper surface of the connecting disc 22; a feeding groove 230 is provided on the outer ring surface of the clamping disc 23, and a lateral abutment component is provided on the inner side of the feeding 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 feeding groove 230 through a pin shaft, and an elastic block 2302 and a triangular abutment piece 2303 are fixedly connected to the inner side of one end 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 opened on one side of the feeding groove 230 2300, an end abutment assembly is provided on the inner side of the buffer chamber 2300, and the end abutment assembly includes a abutment rod 231 and an abutment spring 232. The abutment rod 231 is composed of a contact plate 2311 and a contact rod 2312. The end of the contact rod 2312 away from the contact plate 2311 is fixedly connected to a connecting vertical rod 233, and 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 miscellaneous pushing inclined block 235, and the miscellaneous pushing inclined block 235 is slidably mounted on the inner side of the miscellaneous storage frame 221; In this embodiment, when the terminal workpiece is threaded, the workpiece moves under the propulsion of the electric telescopic rod 31. During this process, the driving motor drives the driving shaft to rotate, keeping the connecting plate 22 and the clamping plate 23 rotating at a certain speed. Figure 3As shown, the terminal processing piece enters the feeding trough 230 aligned with the outlet end of the loading trough plate 3. When the workpiece to be processed reaches the position directly below the tapping unit 12, the control limit abutment plate 261 is pushed toward the side of the workpiece to abut one end of the terminal processing piece. At this time, the other end of the terminal processing piece abuts the inner abutting rod 231, and the abutting 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 abutment on the inner side of the guide arc plate 25, the workpiece reaches the upper end of the unloading guide plate 4. At this time, the abutting rod 231 pushes the workpiece outward, so that the processed terminal processing piece is unloaded along with the unloading guide plate 4. It should be noted that when the terminal enters the inner side of the material loading groove 230, its side contacts the triangular contact piece 2303, and the movable contact plates 2301 on both sides swing to self-clamp the side of the terminal processing part. At the same time, the end of the terminal processing part contacts the contact plate 2311, and the mutual cooperation between the contact rod 231 and the contact spring 232 can buffer the processing part, thereby preventing the clamping plate 23 from being directly impacted by the pushing terminal, thereby extending the service life of the equipment. It is worth noting that, referring to Figure 5 As shown, this state is the effect of the support rod 231 being pushed forward by force, as shown in FIG. Figure 6 As shown, this state is the effect of the supporting rod 231 pushing out the buffer cavity 2300 and pushing the workpiece. When the supporting rod 231 is pushed inward by external force, the connecting vertical rod 233 connected to one end of the supporting rod 231 away from the contact plate 2311 drives the pushing rod 234 to move inward. At this time, the pushing inclined block 235 slides to the inner side of the storage frame 221. Conversely, when the pushing inclined block 235 moves outward, the pushing inclined block 235 can automatically push out the tapping impurities accumulated on the inner side of the storage frame 221.

[0022] Example 2, refer to the attached Figure 1-17 Based on the first embodiment, in order to collect the tapping chips and tapping coolant: The inner wall of the outer ring of the connecting plate 22 is respectively provided with a mounting groove 220, and the inner surface of the mounting groove 220 is movably embedded with a storage frame 221, and one end of the outer side of the storage frame 221 is movably connected to a movable sealing plate 222, and 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, and the two ends of the pin are respectively rotatably connected to the inner wall of the storage frame 221, and a torsion spring is sleeved and installed at both ends of the pin; through the cooperation of the pin and the torsion spring, it can be ensured that the movable sealing plate 222 automatically resets after losing its magnetism, thereby realizing automatic blocking of the storage frame 221; In this embodiment, the connecting plate 22 is rotatably mounted on the upper side of the fixed seat 21, and corresponding mounting grooves 220 are opened at the corresponding positions of the connecting plate 22 and the material feeding groove 230, and storage frames 221 are installed one by one. The storage frames 221 here can temporarily store the debris generated by tapping. It should be noted that the diameter of the mounting groove 220 is smaller than the diameter of the material feeding groove 230. When the terminal processing part enters the inner side of the material feeding groove 230, the top of the storage frame 221 can receive 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 blanking guide plate 4 is close to the clamping An adaptive electromagnet 2 is installed on the surface of one side of the material tray 23. When a group of storage frames 221 reaches the position of the unloading guide plate 4, electromagnet 1 and electromagnet 2 are energized. At this time, electromagnet 1 will drive the movable sealing plate 222 to move closer to the side of the unloading guide plate 4, thereby realizing the automatic opening of the movable sealing plate 222. At this time, the terminal processing piece is also pushed out by the supporting rod 231, and the impurity pushing bevel 235 is synchronously pushed outward for a distance to push out the impurities accumulated on the inside of the storage frame 221, which not only meets the unloading of the workpiece, but also meets the automatic opening and closing of the movable sealing plate 222, and can also realize the self-cleaning of impurities.

[0023] Example 3, refer to the attached Figure 1-17 On the basis of the second embodiment, in order to achieve stability when feeding the terminal processing parts: The limit frame 26 is fixedly mounted on the inner side of the back end of the tapping table 11, and the guide arc plate 25 is fixedly mounted on the upper surface of the tapping table 11 by bolts.

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, and the connecting wing plate 2611 is provided with two groups and is mirror-imaged about the central axis of the limit plate 261. The connecting wing plate 2611 is fixedly mounted on both sides of the limit plate 261, and the outer surface of the connecting wing plate 2611 is meshed and rotated with a linkage gear 2612, and the other side of the linkage gear 2612 is meshed and rotated with a swing holding rod 2613. The swing holding rod 2613 is composed of a half gear and a bent plate, and the outer surface of the bent plate is respectively engaged with the connecting disk 22 and the clamping plate The outer surface of the disk 23 is movably abutted; an elastic support member is provided between the inner side of the swing holding rod 2613 and the arc-shaped receiving groove 2500, and the elastic support member 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 receiving groove 2500, and the other end of the arc-shaped support rod 2614 is fixedly connected to the inner curved surface of the swing holding rod 2613, and the sliding collar 2615 is slidably arranged. Mounted on the outer surface of the arc-shaped support rod 2614, one end of the sliding collar 2615 is fixedly connected to a sleeve elastic wire 2616. The sleeve elastic wire 2616 is slidably mounted on the outside of the arc-shaped support rod 2614, and the other end of the sleeve elastic wire 2616 is fixedly connected to the outer surface of the bent plate. The outer side surface of the sliding collar 2615 is rotatably connected to one end of an abutment rod 2617, and the other end of the abutment rod 2617 is movably connected to the inner surface of the arc-shaped receiving groove 2500. In this embodiment, when the limit plate 261 is driven to move toward the clamping plate 23, the outer end of the limit plate 261 abuts the workpiece below the forward tapping unit 12. At the same time, the workpieces distributed on both sides of the tapping workpiece are abutted synchronously to avoid vibration. Specifically, refer to Figure 12-13 As shown, when the limit support plate 261 is pushed toward one side of the workpiece, the connecting wing plates 2611 on both sides thereof move synchronously, so that the linkage gears 2612 on both sides are adapted to mesh. At this time, the linkage gear 2612 rotates 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 to avoid vibration or offset. It is worth noting that, through the setting of the elastic support member, dynamic compensation is provided for the clamping action of the swing arm 2613, and strength support can be provided for the swing arm 2613 to avoid the swing arm 2613 from stably supporting the workpiece when the workpiece is tapped, thereby further improving the tapping effect of the workpiece.

[0024] Example 4, refer to the attached Figure 1-17 On the basis of the third embodiment, in order to realize the rapid unloading and auxiliary cleaning of the terminal processing parts: The center inner side of the clamping disc 23 is fixedly connected with a sleeve ring 24, which passes through the center inner wall of the clamping disc 23 and the connecting disc 22 and is fixedly connected to the outer surface of the driving shaft; a boosting pipe 241 is provided on the upper inner wall of the sleeve ring 24, and the outlet end of the boosting pipe 241 extends to the inner side of the buffer chamber 2300. The input end of the boosting pipe 241 is connected to a boosting pump, which is installed on the upper surface of the sleeve ring 24.

The inner surface of the tapered groove is threadedly connected to a threaded tapered cover 2313. In this embodiment, when the tapped terminal workpiece reaches the top of the blanking guide plate 4, the boost pipe 241 is controlled to open and the boost gas is introduced into the inner side of the buffer chamber 2300.
