Description

Technical Field

[0001] This invention relates to the field of metal sealing component processing technology, specifically to a precision fitting processing technology and device for pipeline plugging equipment. Background Technology

[0002] Metal seals are core precision components used in pipeline plugging, container sealing, and equipment interface sealing. They are widely used in oil and gas, chemical, water supply and drainage, and rail transportation industries. As industrial equipment upgrades towards higher reliability, longer lifespan, and automation, the market has placed higher demands on the batch processing efficiency, dimensional consistency, and purely mechanical adaptability of metal seals. The technical shortcomings of traditional processing equipment are gradually becoming apparent.

[0003] Patent publication number CN218776303U relates to the field of metal seal processing, including a bottom chamber. The upper outer surface of the bottom chamber is equipped with a baffle plate, a controller, and a pneumatic push rod. The pneumatic push rod allows for easy adjustment of the processing height of the metal seal, facilitating processing at different heights and adapting to different processing equipment. Processing debris falls onto the bottom chamber and is blocked by the baffle plate. The debris can be cleaned into the bottom chamber through a drain hole. For long-term use, the debris can be removed by opening the front door. The first limiting rod can be fixed to the metal seal from the inside using a fixing plate, facilitating external processing of the metal seal. The second limiting rod can be fixed to the metal seal from the outside using a fixing plate, facilitating internal processing of the metal seal.

[0004] The aforementioned patent has obvious limitations in practice: if no limit logic for unlocking when the workpiece is in place is set, the clamping mechanism may perform the clamping action when there is no workpiece, causing the grippers to collide directly and resulting in wear of the grippers. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a precision fitting process and apparatus for pipeline plugging equipment, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a precision fitting and processing device for pipeline plugging equipment, comprising a fixing frame, wherein a fixing plate is fixedly mounted on the top of the fixing frame, and the processing device further comprising:

[0007] A positioning device is installed on the surface of the worktable to fix the position of the workpiece;

[0008] A workbench, which is fixedly mounted on the top of a fixed plate;

[0009] A clamping mechanism is disposed on the surface of the worktable. The clamping mechanism includes a sliding seat and clamping claws. The sliding seat is disposed on the surface of the clamping mechanism, and the clamping claws are threaded onto the inner wall of the sliding seat. The clamping claws on both sides are configured to be nested sliding fit, so that when the solid claw slides into the inner side of the hollow claw, the minimum size of the clamping opening can be reduced; when it slides out, the maximum size is expanded.

[0010] A protective mechanism, comprising a mounting rod, a sliding rod, a limiting block, and a driving rod, wherein the mounting rod is fixedly mounted on the surface of the workbench, the sliding rod is slidably mounted on the inner wall of the mounting rod, the limiting block is fixedly mounted on the top of the sliding rod, and the driving rod is fixedly mounted on the bottom of the sliding rod;

[0011] The discharge device is installed on the surface of the worktable to realize the automatic output of workpieces;

[0012] The detection device, located below the fixed plate, is used to detect defects on the surface of the workpiece.

[0013] According to the above technical solution, a slot is provided at the bottom of the sliding seat, and a first spring is provided on the surface of the sliding seat. The first spring buffers the impact force of the clamping claw. The top of the limiting block is set as an inclined surface. When the sliding seat is reset, its outer wall first contacts the inclined surface of the limiting block, so that the limiting block is forced downward and drives the sliding rod downward, while simultaneously compressing the first spring. When the limiting block moves to overlap with the slot, the first spring resets and drives the limiting block to insert into the slot, so as to continue to limit the sliding seat. A second spring is provided between the sliding rod and the mounting rod, and the second spring drives the sliding rod to reset.

[0014] According to the above technical solution, the positioning device further includes a connecting frame, an X-axis assembly, a Y-axis assembly, and a mounting plate. The connecting frame is fixedly mounted on the surface of the fixed frame, the X-axis assembly is disposed on the surface of the connecting frame, the Y-axis assembly is disposed on the surface of the X-axis assembly, and the mounting plate is disposed on the surface of the Y-axis assembly. By mounting the machining head on the mounting plate, the machining head is then moved in a dual-axis manner through the X-axis assembly and the Y-axis assembly.

[0015] According to the above technical solution, the discharge device includes a placement frame, a slide rail, an elastic telescopic rod, and a receiving plate. The placement frame is fixedly installed on the top of the fixed plate, the slide rail is fixedly installed on the top of the fixed plate, the fixed end of the elastic telescopic rod is slidably installed on the circumferential surface of the slide rail, and the receiving plate is fixedly installed on the movable end of the elastic telescopic rod. After the workpiece is placed on the surface of the placement frame, it is pushed into the circular hole of the placement frame. At this time, the bottom of the workpiece is supported by the bottom of the receiving plate. The weight of the workpiece itself causes the receiving plate to move downward. The movement of the receiving plate causes the movable end of the elastic telescopic rod to retract.

[0016] According to the above technical solution, the discharge device further includes a traction rod, a rotary knob, a brake rod, and a pressure rod. The traction rod is fixedly installed at the bottom of the sliding seat. The rotary knob is rotatably installed on the inner wall of the traction rod. A reset torsion spring is provided between the rotary knob and the traction rod. The reset torsion spring is used to reset the rotary knob. An anti-wear sleeve is provided on the surface of the rotary knob. The brake rod is rotatably installed on the surface of the receiving plate. A reset torsion spring is provided between the brake rod and the receiving plate. The reset torsion spring is used to reset the brake rod. The pressure rod is fixedly installed on the surface of the receiving plate. The rotary knob is set to rotate in one direction. When the receiving plate moves to its maximum distance, the rotary knob continues to move. This movement causes the brake rod to rotate and stretch the reset torsion spring, causing the rotary knob to move to the other side of the brake rod. At this time, the receiving plate moves out of the placement frame range, causing the workpiece to fall naturally without support at the bottom.

[0017] According to the above technical solution, the discharge device further includes a deceleration rod and a lever. The deceleration rod is rotatably mounted on the inner wall of the fixed plate, and the lever is fixedly mounted on the surface of the deceleration rod. A reset torsion spring is provided between the deceleration rod and the fixed plate. The reset torsion spring drives the deceleration rod to reset. A rubber block is provided on the surface of the deceleration rod to buffer the falling of the workpiece under the setting of the deceleration rod and the reset torsion spring.

[0018] According to the above technical solution, the detection device includes a mechanical counter, an observation window, and a gear rod. The mechanical counter is installed on the inner wall of the fixed plate, the observation window is fixedly installed on the surface of the fixed plate, and the gear rod is installed on the surface of the mechanical counter. When the workpiece falls, the gear rod is rotated by a lever. The rotation of the gear rod causes the gear inside the mechanical counter to rotate, which in turn causes the ratchet of the mechanical counter to rotate one increment. The dial of the mechanical counter accumulates the value synchronously. The operator can observe the output quantity of the workpiece in real time through the observation window.

[0019] According to the above technical solution, the detection device further includes a motor frame, a mounting frame, an electric push rod, and an arc plate. The motor frame is fixedly installed on the inner wall of the fixed frame, the mounting frame is fixedly installed on the surface of the motor frame, the fixed end of the electric push rod is fixedly installed on the surface of the mounting frame, and the arc plate is fixedly installed on the output end of the electric push rod. A sensor is provided on the inner wall of the arc plate. The electric push rods on both sides drive the respective arc plates to move. The movement of the arc plates drives the detection brush to move, and the movement of the detection brush will contact the outer wall of the workpiece.

[0020] According to the above technical solution, the detection device further includes a detection brush, a rotating frame, a magnetic chuck, and an output plate. The detection brush is slidably mounted on the surface of the arc-shaped plate. The rotating frame is fixedly mounted on the output end of the motor frame, and a motor is provided on the surface of the rotating frame. One side of the magnetic chuck is rotatably mounted on the inner wall of the rotating frame, and the other side of the magnetic chuck is fixedly mounted on the output end of the motor. The output plate is fixedly mounted on the surface of the motor frame. If there are defects such as burrs, scratches, or pits on the surface of the workpiece, the detection brush will be hooked and generate lateral force to slide along the inner wall of the arc-shaped plate, while simultaneously triggering the response threshold of the sensor.

[0021] Furthermore, the present invention also provides a process for a precision fitting and processing device for pipeline plugging equipment, which uses the aforementioned precision fitting and processing device for pipeline plugging equipment and includes the following steps:

[0022] Step 1: The machining head is mounted on the mounting plate, and then the machining head is moved in two axes by the X-axis assembly and the Y-axis assembly. After the workpiece is placed, the sliding seats on both sides are driven to move relative to each other by the clamping mechanism. The movement of the sliding seats will drive the clamping jaws to move and clamp the workpiece.

[0023] Step 2: While clamping, the impact force of the clamping claw is buffered by the No. 1 spring set on the surface of the sliding seat to prevent damage to the workpiece or clamping claw due to rigid collision;

[0024] Step 3: When the sliding seat is in its original state, it is restricted by the limiting block through the slot at the bottom. The power transmission link of the clamping mechanism will only be connected when the workpiece is completely dropped into the slot and the limiting is released.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In this invention, the positioning device drives the clamping claw to move via the sliding seat. When the sliding seat is in its original state, it is restricted by the limiting block through the slot at the bottom. If the limiting logic for unlocking when the workpiece is in place is not set, the clamping mechanism may perform the clamping action when there is no workpiece, causing the clamping claw to collide directly, resulting in wear of the clamping claw, breakage of the lead screw thread, or damage to the transmission gear. This mechanism ensures through mechanical principle that the power transmission link of the clamping mechanism will only be connected when the limit is triggered after the workpiece is fully placed in the subsequent structure, thus avoiding empty clamping impact from the root and extending the service life of the device.

[0027] 2. In this invention, the bottom of the workpiece is supported by the bottom receiving plate through the setting of the discharge device. The weight of the workpiece itself causes the receiving plate to move downward, thereby releasing the sliding seat from the restriction. The processing accuracy of the metal sealing plug is highly dependent on the clamping and positioning accuracy. The only prerequisite for releasing the limit is that the workpiece is placed in the correct position, forcing the workpiece to fall into the reference positioning position of the fixture. Then, the clamping mechanism drives the clamping claws to clamp synchronously. The receiving plate moves out of the placement frame, so that the bottom of the workpiece is unsupported and falls naturally. The drop of the workpiece is buffered by the deceleration rod and the reset torsion spring. Free fall without buffer will cause the workpiece to be in a chaotic posture. Subsequent sorting, quality inspection, counting and other processes need to be manually sorted, which affects the automation efficiency. The buffering mechanism can force the workpiece to be aligned along the preset trajectory while decelerating, ensuring that the workpiece is accurately positioned when it enters the subsequent detection mechanism. No additional posture correction steps are required, which improves the efficiency of the entire process automation connection.

[0028] 3. In this invention, the detection device uses a magnetic chuck to attract workpieces. As the workpiece falls, a lever rotates the gear rod, causing the ratchet of the mechanical counter to rotate one increment. The counter's dial simultaneously increments the value. Workers can observe the number of workpieces being processed in real time through an observation window. This linkage design indirectly reflects the processing and output status of the device, providing a fault warning. When a workpiece is on the magnetic chuck, if there are defects such as burrs, scratches, or dents on its surface, the detection brush will be hooked and generate lateral force, sliding along the inner wall of the curved plate and simultaneously triggering the sensor's response threshold, achieving accurate defect identification. When a defective workpiece is detected, the sensor controls the motor to drive the magnetic chuck to tilt to the right and simultaneously release the magnetic attraction. At this time, the output end of the electric push rod resets, causing the workpiece to fall to the right and finally onto the output plate. If the workpiece is intact, it tilts to the left for output, enabling automated workpiece sorting and reducing reliance on manual labor. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1:

[0043] Please see Figures 1-10 One embodiment of the present invention is: a precision fitting processing device for pipeline plugging equipment, which includes a fixing frame 1, a fixing plate 2 fixedly installed on the top of the fixing frame 1, and the processing device further includes:

The threaded connection is a detachable structure. When the clamping claw 13 is worn, damaged, or needs to be replaced with a different specification, it can be quickly disassembled and replaced without scrapping the entire clamp, thus reducing maintenance costs.

[0047] The protective mechanism includes a mounting rod 15, a sliding rod 16, a limiting block 18, and a driving rod 19. The mounting rod 15 is fixedly mounted on the surface of the workbench 10, the sliding rod 16 is slidably mounted on the inner wall of the mounting rod 15, the limiting block 18 is fixedly mounted on the top of the sliding rod 16, and the driving rod 19 is fixedly mounted on the bottom of the sliding rod 16.

[0048] The discharge device is installed on the surface of the worktable 10 to realize the automatic output of the workpiece;

[0049] The detection device is located below the fixed plate 2 and is used to detect defects on the surface of the workpiece.

[0050] The bottom of the sliding seat 12 is provided with a slot 121, and a first spring 14 is provided on the surface of the sliding seat 12. The top of the limiting block 18 is set as an inclined surface. The inclined surface allows the position of the sliding seat 12 to be automatically re-limited after the sliding seat 12 is reset. A second spring 17 is provided between the sliding rod 16 and the mounting rod 15.

[0051] The positioning device also includes a connecting frame 3, an X-axis assembly 4, a Y-axis assembly 5, and a mounting plate 6. The connecting frame 3 is fixedly mounted on the surface of the fixed frame 1, the X-axis assembly 4 is disposed on the surface of the connecting frame 3, the Y-axis assembly 5 is disposed on the surface of the X-axis assembly 4, and the mounting plate 6 is disposed on the surface of the Y-axis assembly 5, so as to move the machining head in two axes.

[0052] The discharge device includes a placement frame 20, a slide rail 21, an elastic telescopic rod 22, and a receiving plate 23. The placement frame 20 is fixedly installed on the top of the fixed plate 2, the slide rail 21 is fixedly installed on the top of the fixed plate 2, the fixed end of the elastic telescopic rod 22 is slidably installed on the circumferential surface of the slide rail 21, and the receiving plate 23 is fixedly installed on the movable end of the elastic telescopic rod 22. The receiving plate 23 moves downward by the weight of the workpiece itself, and the movement of the receiving plate 23 causes the movable end of the elastic telescopic rod 22 to retract.

[0053] The discharge device also includes a traction rod 24, a rotary knob 25, a brake rod 26, and a pressure rod 27. The traction rod 24 is fixedly installed at the bottom of the sliding seat 12.

An anti-wear sleeve is provided on the surface of the rotary knob 25. The brake rod 26 is rotatably installed on the surface of the receiving plate 23. A reset torsion spring is provided between the brake rod 26 and the receiving plate 23. The pressure rod 27 is fixedly installed on the surface of the receiving plate 23, causing the receiving plate 23 to move out of the range of the placement frame 20, so that the bottom of the workpiece is unsupported and falls naturally.

[0054] The discharge device also includes a deceleration rod 28 and a lever 29. The deceleration rod 28 is rotatably mounted on the inner wall of the fixed plate 2, and the lever 29 is fixedly mounted on the surface of the deceleration rod 28. A reset torsion spring 3 is provided between the deceleration rod 28 and the fixed plate 2. Rubber blocks are provided on the surface of the deceleration rod 28. Since the deceleration rod 28 is arranged in a circular array, the rubber blocks at the contact points between the workpiece and the workpiece will generate a radial elastic support force pointing towards the center of the circle, forcing the workpiece to move in the direction aligned with the central axis. If the workpiece is tilted, the frictional resistance of the rubber blocks at different contact points is different, forming a corrective torque around the central axis, pushing the workpiece to move towards an attitude parallel to the central axis, so that the workpiece is forced to straighten its attitude along a preset trajectory, ensuring accurate positioning when the workpiece enters the subsequent inspection mechanism.

[0055] The detection device includes a mechanical counter 30, an observation window 31, and a gear rod 32. The mechanical counter 30 is installed on the inner wall of the fixed plate 2, the observation window 31 is fixedly installed on the surface of the fixed plate 2, and the gear rod 32 is installed on the surface of the mechanical counter 30. It can indirectly reflect the processing and discharging conditions of the device and play a role in fault early warning.

A sensor is provided on the inner wall of the arc plate 36. When a defective workpiece is detected, the sensor controls the motor to drive the magnetic chuck 39 to tilt.

[0057] The detection device also includes a detection brush 37, a rotating frame 38, a magnetic chuck 39, and an output plate 310. The detection brush 37 is slidably mounted on the surface of the arc plate 36. The rotating frame 38 is fixedly mounted on the output end of the motor frame 33. A motor is provided on the surface of the rotating frame 38.

The output plate 310 is fixedly mounted on the surface of the motor frame 33. If the workpiece is intact, it tilts to the left for output, so that the workpiece is automatically sorted and the reliance on manual labor is reduced.

[0058] Example 2:

[0059] Based on Example 1, this example uses the processing device from Example 1. The process for a precision fitting processing device for a pipe plugging device provided in this example includes the following steps:

[0060] Step 1: The machining head is mounted on the mounting plate 6, and then the machining head is moved in two axes by the X-axis assembly 4 and the Y-axis assembly 5. After the workpiece is placed, the sliding seats 12 on both sides are driven to move relative to each other by the clamping mechanism 11. The movement of the sliding seats 12 will drive the clamping claws 13 to move and clamp the workpiece.

[0061] Step 2: While clamping, the impact force of the clamping claw 13 is buffered by the No. 1 spring 14 set on the surface of the sliding seat 12 to prevent the workpiece or the clamping claw 13 from being damaged by rigid collision.

[0062] Step 3: When the sliding seat 12 is in its original state, it is restricted by the limiting block 18 through the slot 121 at the bottom. The power transmission link of the clamping mechanism 11 will only be connected when the workpiece is completely dropped into the slot and the limiting is released.

[0063] In this embodiment, the solution expands upon the metal sealing plug as a sealing component. The machining head is mounted on the mounting plate 6, and then the X-axis assembly 4 and Y-axis assembly 5 move the machining head along two axes. After the workpiece is placed, the clamping mechanism 11 drives the sliding seats 12 on both sides to move relative to each other. The movement of the sliding seats 12 causes the clamping jaws 13 to move. The clamping jaws 13 on both sides are designed with a nested sliding fit, so that when the solid jaw slides into the hollow jaw, the minimum size of the clamping opening is reduced; when it slides out, the maximum size is expanded, allowing it to accommodate more different... Workpieces of various diameters and sizes are threaded onto the inner wall of the sliding seat 12 via clamping jaws 13. The threaded connection is a detachable structure, allowing for quick disassembly and replacement when clamping jaws 13 are worn, damaged, or require replacement with different specifications, eliminating the need for complete fixture scrapping and reducing maintenance costs. During clamping, a first spring 14 buffers the impact force of the clamping jaws 13, preventing damage to the workpiece or clamping jaws 13 due to rigid collisions and reducing vibration during clamping. When the sliding seat 12 is in its original state, it is restricted by the limiting block 18 via the slot 121 at the bottom. Without a limit logic for workpiece placement and unlocking, the clamping mechanism 11 may perform a clamping action when there is no workpiece, causing the clamping claws 13 to collide directly, resulting in wear of the clamping claws 13, breakage of the lead screw threads, or damage to the transmission gears. This mechanism ensures through mechanical principles that the power transmission link of the clamping mechanism 11 is only connected when the workpiece is fully placed and the limit is triggered, thus avoiding empty clamping impact at the source and extending the service life of the device. When the drive rod 19 is triggered, it moves downward, which in turn moves the sliding rod 16 downward. The movement of the sliding rod 16 will then move the limit... The movement of the positioning block 18 causes the limiting block 18 to disengage from the slot 121 of the sliding seat 12, allowing the sliding seat 12 to be released from its restriction and move normally with the rotation of the clamping mechanism 11. When the sliding seat 12 is reset, its outer wall first contacts the inclined surface of the limiting block 18, causing the limiting block 18 to be forced downward, which in turn drives the sliding rod 16 to move downward, and at the same time compresses the second spring 17. When the limiting block 18 moves to overlap with the slot 121, the second spring 17 resets and drives the limiting block 18 to insert into the slot 121, so that the sliding seat 12 is still limited.

[0064] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the precision fitting and processing device for pipeline plugging equipment further includes a discharge device and a detection device.

[0065] In this embodiment, the workpiece is placed on the surface of the placement rack 20 and then pushed into the circular hole of the placement rack 20. At this time, the bottom of the workpiece is supported by the bottom support plate 23. The weight of the workpiece itself causes the support plate 23 to move downward. The movement of the support plate 23 causes the movable end of the elastic telescopic rod 22 to retract, so that the support plate 23 moves the brake rod 26 and the pressure rod 27 downward at the same time. The movement of the pressure rod 27 will contact the drive rod 19, causing the drive rod 19 to move downward and drive the sliding rod 16 to move. The movement of the sliding rod 16 will drive the limiting block 18 to move downward, while compressing... When the second spring 17 and the limiting block 18 move downwards, they will disengage from the slot 121 of the sliding seat 12, thus releasing the sliding seat 12 from its constraint. The machining accuracy of the metal sealing plug is highly dependent on the clamping and positioning accuracy. Placing the workpiece in the correct position is the only prerequisite for releasing the limit, forcing the workpiece to fall into the reference positioning position of the fixture. Then, the clamping mechanism 11 drives the clamping jaws 13 to clamp synchronously. The movement of the sliding seat 12 drives the traction rod 24 to move, which in turn drives the rotary knob 25 to move. The rotary knob 25 is set to rotate in one direction. When the rotary knob 25 moves, it will contact the brake lever 26. When the brake lever 26 moves, it will contact the brake lever 26. The knob 25 can be rotated outwards, causing it to rotate and compress the first return torsion spring, eventually moving to the other side of the brake lever 26. When the sliding seat 12 resets, the knob 25 resets and contacts the brake lever 26, causing the brake lever 26 to move the receiving plate 23 along the slide rail 21. However, the force at this time is insufficient to make the brake lever 26 rotate. When the receiving plate 23 moves to its maximum distance, the knob 25 continues to move. This movement causes the brake lever 26 to rotate and stretches the second return torsion spring, causing the knob 25 to move to the other side of the brake lever 26. At this time, the receiving plate 23 moves out of the placement rack. The range of 20 allows the workpiece to fall naturally without support at the bottom. The falling workpiece will contact the deceleration rod 28, causing the deceleration rod 28 to rotate downwards and simultaneously drive the lever 29 to move. This, combined with the deceleration rod 28 and the reset torsion spring, buffers the fall of the workpiece. Unbuffered free fall will cause the workpiece to become disoriented, requiring manual sorting, quality inspection, and counting processes, which affects automation efficiency. The buffer mechanism can decelerate the workpiece while forcing it to straighten its posture along a preset trajectory, ensuring accurate positioning when the workpiece enters the subsequent inspection mechanism. No additional posture correction steps are required, improving the efficiency of the entire automated process.

[0066] The workpiece falls onto the surface of the magnetic chuck 39, where it is attracted. Simultaneously, the lever 29 rotates the gear rod 32, causing the gear inside the mechanical counter 30 to rotate, which in turn rotates the ratchet of the mechanical counter 30 by one increment. The dial of the mechanical counter 30 synchronously increments. Operators can observe the number of workpieces being processed in real time through the observation window 31. This linkage design indirectly reflects the processing and output status of the device, serving as a fault warning. During normal production, the rate of increase of the mechanical counter 30 is consistent with the processing cycle. If a workpiece jams or the clamping mechanism 11 fails to release the workpiece, the mechanical counter 30 will stop increasing or show an abnormal rate of increase. Operators can visually identify the problem through the dial, promptly troubleshoot the fault, and avoid the accumulation of defective products or equipment idling losses. When the workpiece is on the magnetic chuck 39, it is moved by the two sides... The electric push rod 35 drives the respective arc plate 36 to move. The movement of the arc plate 36 drives the detection brush 37 to move. When the detection brush 37 moves, it will contact the outer wall of the workpiece. At this time, the output end of the motor frame 33 drives the rotating frame 38 to rotate. The rotation of the rotating frame 38 drives the magnetic chuck 39 to rotate, causing the workpiece to rotate. If there are defects such as burrs, scratches, pits or other defects on the surface of the workpiece, the detection brush 37 will be hooked and generate lateral force to slide along the inner wall of the arc plate 36 and trigger the response threshold of the sensor at the same time, so as to achieve accurate identification of defects. When a defective workpiece is detected, the sensor controls the motor to drive the magnetic chuck 39 to tilt to the right and release the magnetic adsorption at the same time. At this time, the output end of the electric push rod 35 is reset, so that the workpiece falls to the right and finally falls onto the output plate 310. If the workpiece is intact, it tilts to the left for output, so that the workpiece is automatically sorted and the manual labor is reduced.
