Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, specifically to an anti-slip material pulling machine for bolt processing. Background Technology

[0002] An anti-slip bar puller for bolt processing is an automated device used in the fastening production process. It is primarily used to clamp, convey, and position metal bars to ensure the stability and efficiency of the processing. The anti-slip design is a key technology of this type of equipment, preventing the bar from slipping or shifting during the pulling process, thereby improving processing accuracy and reducing scrap rates.

[0003] In the existing technology, traditional cylinder-driven material extractors are widely used. They use a single cylinder for linear drive and directly push the bar stock through a rigid push rod. One end of the push rod is equipped with a V-shaped gripper, which is in rigid contact with the bar stock. If there is oil on the surface of the bar stock, the friction coefficient between the V-shaped gripper and the surface of the bar stock will decrease, which can easily lead to slippage and over-clamping. This results in unstable material extraction during the working process. Therefore, an anti-slip material extractor for bolt processing is designed. Utility Model Content

[0008] As a preferred embodiment of this utility model, the top end of the support frame is symmetrically rotatably connected to two rotating shafts, and the top ends of the two rotating shafts are fixedly connected to two gears, with the outer walls of the two gears meshing together.

[0009] As a preferred embodiment of this utility model, the outer wall of the support frame is symmetrically provided with two inner grooves at the end near the rotating shaft.

[0012] As a preferred embodiment of this utility model, the bottom end of the sliding plate is slidably connected to the upper surface of the support platform, a telescopic rod is fixedly connected to the end of the sliding plate away from the spring rod, and a cylinder is provided at the end of the telescopic rod away from the sliding plate.

[0013] As a preferred embodiment of this utility model, the inner wall of the gripper rod is rotatably connected with several rollers, and the end of the spring rod away from the cylinder is fixedly connected with a push block.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] 1. This utility model improves the stability of material feeding by setting a spring rod and a gripper rod at the top of the support platform. The cooperation between the spring rod and the gripper rod improves the stability of material feeding. After the cylinder pushes the sliding plate, the sliding plate pushes the spring rod against the outer wall of the bar. The reaction force of the bar pushes the spring rod back. The spring rod pulls the gripper rod through the connecting rod, and the gripper rod clamps and fixes the bar. The mutual clamping of the gripper rod and the spring rod improves the stability of material feeding and automatically adapts to bars of different diameters, thereby achieving precise and stable feeding of the bar.

When bars of different sizes slide between the adjusting plates for conveying, the operator can rotate the double-threaded rod to adjust the spacing. When the double-threaded rod rotates, it engages with the inner wall of the adjusting plate through a threaded engagement. This threaded engagement drives the two adjusting plates to move synchronously, and the adjusting plates then push the guide plate to adjust the spacing between the clamping bars, thereby enabling stable conveying of bars of different sizes.

[0032] like Figures 1-6 The diagram illustrates an anti-slip bolt pulling machine according to an embodiment of the present invention. It includes a support platform 1, a support frame 2 fixedly connected to the top of the support platform 1, a conveyor belt 201 connected to the inner wall of the support frame 2, a ramp 4 at one end of the support platform 1 near the conveyor belt 201, two adjusting plates 402 symmetrically slidably connected to the upper surface of the ramp 4, and a guide plate 404 fixedly connected to the outer wall of the adjusting plates 402. The upper surface of the support platform 1, located near the guide plate 404, is fixedly connected to... There is a guide rail plate 5, and a sliding plate 501 is slidably connected to the inner wall of the guide rail plate 5. A spring rod 503 is slidably connected to the inner wall of the sliding plate 501. Two connecting rods 507 are symmetrically hinged to the outer wall of the spring rod 503. Two gripper rods 504 are symmetrically hinged to one side of the sliding plate 501. The end of the connecting rod 507 away from the spring rod 503 is hinged to the inner wall of the gripper rod 504. A flip plate 6 is rotatably connected to the end of the support platform 1 near the spring rod 503. A positioning block 601 is fixedly connected to the top of the flip plate 6.

[0033] Specifically, the inner wall of the support frame 2 is symmetrically rotatably connected with two gears 202, and the inner wall of the conveyor belt 201 is surrounded by several internal teeth 203, the inner wall of the internal teeth 203 meshing with the outer wall of the gears 202.

[0034] A motor 204 is fixedly connected to the outer wall of the support frame 2. The output end of the motor 204 extends into the inner wall of the support frame 2, and the output end of the motor 204 is fixedly connected to the inner wall of one of the gears 202.

[0035] It should be noted that the inner walls of both gears 202 are fixedly connected to shafts, which pass through the support frame 2. The conveyor belt 201 meshes with the outer walls of the two gears 202 through the internal teeth 203. The outer wall of the shaft of one of the gears 202 is fixedly connected to a motor 204. After the motor 204 is started, it drives the gear 202 to rotate. The rotation of the gear 202 drives the conveyor belt 201 to transmit power through meshing.

[0036] Specifically, the top of the support frame 2 is symmetrically connected to two rotating shafts 3, and the top of the two rotating shafts 3 is fixedly connected to two gears 301, which are meshed on the outer walls.

[0037] The outer wall of the support frame 2 is symmetrically provided with two inner grooves 303 at the end near the rotating shaft 3. The outer wall of the rotating shaft 3 at the end away from the gear 301 is fixedly connected with a cross lever 302. The outer wall of the cross lever 302 is rotatably connected to the inner wall of the inner groove 303.

[0038] It should be noted that when multiple bars are conveyed by the conveyor belt 201, the bars will first come into contact with the cross lever 302. The bars will push the cross lever 302 to rotate. The cross lever 302 drives one of the rotating shafts 3 to rotate. The rotating shaft 3 drives one of the gears 301 to rotate. The gears 301 rotate in phase through meshing, thereby realizing the mutual rotation between the two cross levers 302. The mutual rotation of the cross levers 302 isolates the bars from each other, ensuring that each bar does not interfere with the transportation of each other.

[0039] Specifically, the inner wall of another gear 202 is fixedly connected to the sliding shaft 401, and the inner walls of the two adjusting plates 402 are symmetrically slidably connected to the outer wall of the sliding shaft 401.

[0040] Two side baffles 403 are symmetrically fixedly connected to the upper surface of the ramp 4 and the end near the adjusting plate 402. A double threaded rod 405 is threadedly connected to the inner wall of the side baffle 403. The outer wall of the double threaded rod 405 is threadedly connected to the inner wall of the adjusting plate 402.

[0041] It should be noted that the surface of the ramp 4 is provided with a groove, the bottom of the adjusting plate 402 is provided with a block, and the surface of the double threaded rod 405 is provided with two sections of threads in opposite directions. The adjusting plate 402 is threadedly connected to the surface of each section of the thread. After the operator rotates the double threaded rod 405, the double threaded rod 405 pushes the adjusting plate 402 to slide through the thread engagement. The adjusting plate 402 slides on the surface of the ramp 4 using a slider. At the same time, under the engagement of the two sections of threads in opposite directions of the double threaded rod 405, the two adjusting plates 402 slide in opposite directions. Through the reverse sliding of the adjusting plates 402, the sliding transport of bar stock of different sizes is realized.

[0042] Specifically, the bottom end of the sliding plate 501 is slidably connected to the upper surface of the support platform 1, and a telescopic rod 508 is fixedly connected to the end of the sliding plate 501 away from the spring rod 503. A cylinder 502 is provided at the end of the telescopic rod 508 away from the sliding plate 501.

[0043] Several rollers 505 are rotatably connected to the inner wall of the gripper rod 504, and a push block 506 is fixedly connected to the end of the spring rod 503 away from the cylinder 502.

[0044] It should be noted that the surface of the gripper bar 504 is lined with polyurethane, which has a wear-resistant and anti-slip effect. The inner wall of the positioning block 601 is provided with a groove laterally. When the cylinder 502 pushes the telescopic rod 508 and the sliding plate 501, the sliding plate 501 pushes the gripper bar 504 and the spring rod 503 to contact the bar. During the pushing process, the gripper bar 504 and the spring rod 503 will first contact the bar through the groove to clamp it. The spring rod 503 resists the bar with elasticity and retracts with reaction force. The spring rod 503 pulls back the gripper bar 504 to clamp and fix the bar. After clamping, the bottom of the sliding plate 501 further flips the plate 6, and finally pushes the bar to the inner wall of the guide rail frame 7.

[0045] Specifically, a square frame 603 is fixedly connected to the bottom end of the support platform 1 and the end near the flip plate 6. An arc spring 602 is fixedly connected to the inner wall of the square frame 603. The inner wall of the square frame 603 is slidably connected to the outer wall of the flip plate 6. A guide rail frame 7 is fixedly connected to the end of the support platform 1 near the flip plate 6.

[0046] It should be noted that when the bottom of the sliding plate 501 further pushes and overturns the flip plate 6 and the positioning block 601, the flip plate 6 and the positioning block 601 are compressed by the arc spring 602. Then, the flip plate 6 drives the positioning block 601 to flip to the inner wall of the square frame 603 through the hinge. The flip plate 6 is provided with sliding rods on both sides, and the inner wall of the square frame 603 is provided with arc grooves. The sliding rods slide on the inner wall of the arc grooves. The connection between the arc grooves and the sliding rods stabilizes and guides the flip plate 6 and the positioning block 601 to flip.

[0047] The specific operation is as follows: After the operator starts the machine, motor 204 drives gear 202 to rotate. Gear 202, through meshing with internal gear 203, drives conveyor belt 201 for transmission. During transmission, conveyor belt 201 transports the bar stock one by one. During the transport process, the bar stock pushes against cross lever 302. After being pushed, cross lever 302 rotates, driving rotating shaft 3 to rotate. Rotating shaft 3 drives one of the gears 301 to rotate, and then this gear 301 drives the other gear 301 to rotate. Under the mutual meshing and rotation of gears 301, the two cross levers 302 rotate synchronously. The synchronous rotation of the conveyor belt 201 creates gaps between the bars and arranges them in an orderly manner for transport. After exiting the conveyor belt 201, the bars slide between the guide plates 404 on the outer walls of the two adjusting plates 402. At this point, the bars slide between the guide plates 404 by gravity. The operator can adjust the distance between the two adjusting plates 402 according to the size of the bars. The operator needs to rotate the double threaded rod 405, which engages with the inner wall of the adjusting plate 402. This threaded engagement pushes the two adjusting plates 402 to slide synchronously. The distance between the two adjusting plates 402 is adjusted by sliding to accommodate bars of different sizes.

[0048] Guided by the guide plate 404, the bar stock slides down to the inner wall of the positioning block 601. At this time, the cylinder 502 pushes the telescopic rod 508 to slide, and the telescopic rod 508 pushes the sliding plate 501 to slide on the inner wall of the guide rail plate 5. At this time, the sliding plate 501 pushes the spring rod 503 and the gripper rod 504. When the push block 506 of the spring rod 503 contacts the bar stock inside the positioning block 601, the spring rod 503 is pushed back by the force. The spring rod 503 pulls back the gripper rod 504 through the connecting rod 507. The gripper rods 504 are forced to move closer together and clamp the bar stock. At this time, the telescopic rod 508 continues to push the sliding plate 501. The bottom of the sliding plate 501 will further push the flip plate 6 and the positioning block 601. The flip plate 6 and the positioning block 601 are forced to compress the arc spring 60. 2. Next, the flipping plate 6, through the hinge, drives the positioning block 601 to flip onto the inner wall of the square frame 603. Then, the sliding plate 501 drives the gripper rod 504 to hold the fixed bar and slide it to one end of the guide rail frame 7. When the telescopic rod 508 retracts through the cylinder 502, the telescopic rod 508 pulls the sliding plate 501 and the spring rod 503 in the opposite direction. At this time, the spring rod 503 is subjected to a rebound force and pushes the bar away. At the same time, it pushes the connecting rod 507h and the gripper rod 504 in the opposite direction. The bar is released and placed on the inner wall of the guide rail frame 7. When the sliding plate 501 and the spring rod 503 return to their original positions, the flipping plate 6 and the positioning block 601 continue to return to their original positions using the rebound force of the arc spring 602. Finally, the bar is repeatedly pushed and pulled by the cylinder 502 to realize the bar-pulling operation.
