An assembly device for chain processing

Abstract

This invention relates to the field of chain processing equipment technology, and discloses an assembly device for chain processing, including a housing. A conveyor belt is fixedly installed inside the housing, and a chain is placed in contact with the top of the conveyor belt. A stamping mechanism is fixedly installed inside the housing. The stamping mechanism includes a limiting groove and a servo motor. The limiting groove is located at the top of the housing. The servo motor drives a reciprocating screw to rotate, which in turn drives a lifting sleeve to move downward, thereby driving a connecting plate to move downward. The downward movement of the connecting plate drives a stamping plate to move downward through a T-slot and a T-block. As the stamping plate moves downward, a triangular plate abuts against the stamping plate and moves to the right, so that the stamping plate moves downward and to the right at the same time. By adjusting the rotation speed of the servo motor, the horizontal speed of the stamping plate and the chain on the conveyor belt are kept the same, thus avoiding a speed difference between the stamping plate and the chain, which could cause misalignment between the locking plate and the chain.

Description

Technical Field

[0001] This invention relates to the field of chain processing equipment technology, specifically to an assembly device for chain processing. Background Technology

[0002] Chains are very common in daily life and are widely used in mechanical transmission and vehicles. The most common example is bicycle chains. However, in the production of chains, they need to be continuously processed. After processing, the chains need to be fixed and assembled. Locking plates need to be installed on the outer wall of the chain. Usually, the chain assembly is completed by stamping.

[0003] Chinese patent CN212042527U discloses a circulating assembly device for chain production. This device uses an extrusion mechanism to extrude the chain, allowing it to be formed in one step. A material trough stores the chains to be collected. A limiting block restricts the position of a limiting rod, and an extrusion plate presses the chain. A motor rotates a drive shaft, which in turn rotates a threaded rod. When the threaded rod rotates, it causes the extrusion plate to move up and down. The limiting rod allows the extrusion plate to move vertically.

[0004] However, the cyclic assembly equipment used for chain production uses a threaded rod to drive an extrusion plate to press the chain. In order to ensure sufficient force to press the locking plate into the chain, the lower surface of the extrusion plate needs to contact the locking plate and then continue to move downward to push or press the locking plate into the chain. Therefore, the conveyor belt can only be stopped each time the stamping is performed, because if the conveyor belt is not stopped, the chain will be driven horizontally by the transmission belt, and the locking plate will be pressed down and moved by the extrusion plate, causing the locking plate and the chain to be misaligned. Therefore, it is impossible to achieve uninterrupted chain assembly. Summary of the Invention

[0005] The purpose of this invention is to provide an assembly device for chain processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an assembly device for chain processing, comprising a housing, a conveyor belt fixedly installed inside the housing, a chain placed in contact with the top of the conveyor belt, and a stamping mechanism fixedly installed inside the housing;

[0007] The stamping mechanism includes a limiting groove and a servo motor. The limiting groove is located at the top of the outer shell. The bottom of the servo motor is fixedly connected to the top of the outer shell. A reciprocating lead screw is fixedly installed at the output end of the servo motor. The reciprocating lead screw movably passes through the top outer wall of the outer shell. A lifting sleeve is threaded onto the outer wall of the reciprocating lead screw. A connecting plate is fixedly installed at the bottom of the lifting sleeve. A limiting rod is fixedly installed at the top of the connecting plate. The limiting rod is slidably disposed in the limiting groove. A T-slot is opened at the bottom of the connecting plate. A T-block is slidably disposed on the inner wall of the T-slot. A stamping plate is fixedly installed at the bottom of the T-block. A spring is fixedly installed on the right outer wall of the T-block. The right end of the spring is fixedly connected to the inner wall of the T-slot. A triangular plate is contacted on the left outer wall of the stamping plate. A support rod is fixedly installed on the left outer wall of the triangular plate. One left end of the support rod is fixedly connected to the inner wall of the outer shell.

[0008] A limiting mechanism is fixedly installed on the right outer wall of the housing, and a buffer mechanism is provided below the conveyor belt.

[0009] Preferably, the buffer mechanism includes a fixed base, a damper is fixedly installed on the bottom inner wall of the fixed base, a lifting column is fixedly installed on the top of the damper, a support plate is fixedly installed on the top of the lifting column, a sliding groove is opened on the side outer wall of the lifting column, a slider is slidably arranged on the inner wall of the sliding groove, and the outer wall of the slider is fixedly connected to the inner wall of the fixed base.

[0010] Preferably, the limiting mechanism includes a fixed box, the left outer wall of the fixed box is fixedly connected to the right outer wall of the outer shell, the front of the fixed box is rotatably connected to a bidirectional threaded rod via a bearing, a clamping plate is threadedly connected to a section of the outer wall of the bidirectional threaded rod inside the fixed box, the clamping plate movably passes through the outer walls of the fixed box and the outer shell, the clamping plate is located on both sides of the chain, a turntable is fixedly installed at the front end of the bidirectional threaded rod, and a handle is fixedly installed on the front of the turntable.

[0011] Preferably, a control panel is fixedly installed on the front of the housing, and an observation window is fixedly installed on the front of the housing.

[0012] Preferably, the left side of the stamping plate is an arc-shaped surface, and two T-slots are provided, which are symmetrically distributed at the bottom of the connecting plate.

[0013] Preferably, six dampers are provided and are evenly distributed at the bottom of the lifting column, and the support plate is a rubber plate.

[0014] Preferably, the outer wall of the throttle is fixedly fitted with an anti-slip sleeve, and the outer wall of the clamping plate is fixedly installed with a smooth plate, the outer wall of the smooth plate being in contact with the outer wall of the chain.

[0015] Preferably, the side of the triangular plate that contacts the stamping plate is an inclined surface, and the stamping plate is located directly above the conveyor belt.

[0016] This invention provides an assembly device for chain processing. This assembly device for chain processing has the following advantages:

[0017] (1) The assembly equipment for chain processing drives the reciprocating screw to rotate through the servo motor. The rotation of the reciprocating screw drives the lifting sleeve to move down, which in turn drives the connecting plate to move down. The downward movement of the connecting plate drives the stamping plate to move down through the T-slot and T-block. As the stamping plate moves down, the triangular plate abuts against the stamping plate and moves to the right, so that the stamping plate moves down and to the right at the same time. By adjusting the rotation speed of the servo motor, the speed of the stamping plate and the chain on the conveyor belt are kept the same in the horizontal direction, so as to avoid the speed difference between the stamping plate and the chain, which would cause the locking plate and the chain to misalign.

[0018] (2) When the stamping plate presses down to stamp the chain, the excess kinetic energy is transmitted to the support plate and the lifting column through the conveyor belt. At this time, the damper is squeezed downward to convert the kinetic energy into heat energy, complete the shock absorption, and avoid damage to the conveyor belt.

[0019] (3) The assembly equipment for chain processing rotates the throttle to drive the turntable to rotate according to the size of the chain, which in turn drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives the two clamping plates to move in opposite directions, changing the distance between the two clamping plates, limiting the chain of different sizes, and preventing the chain from running off-track on the conveyor belt.

[0027] Example 1

[0028] A preferred embodiment of the assembly equipment for chain processing provided by the present invention is as follows: Figures 1 to 6 As shown: An assembly device for chain processing includes a housing 1, a conveyor belt 4 fixedly installed inside the housing 1, a chain 5 placed in contact with the top of the conveyor belt 4, and a stamping mechanism 2 fixedly installed inside the housing 1.

[0029] The stamping mechanism 2 includes a limiting groove 204 and a servo motor 2012. The limiting groove 204 is located at the top of the outer shell 1. The bottom of the servo motor 2012 is fixedly connected to the top of the outer shell 1. A reciprocating lead screw 202 is fixedly installed at the output end of the servo motor 2012. The reciprocating lead screw 202 movably passes through the top outer wall of the outer shell 1. A lifting sleeve 201 is threaded onto the outer wall of the reciprocating lead screw 202. A connecting plate 205 is fixedly installed at the bottom of the lifting sleeve 201. A limiting rod 203 is fixedly installed at the top of the connecting plate 205. The limiting rod 203 is slidably disposed within the limiting groove 204. When the reciprocating lead screw 202 is driven to rotate by the servo motor 2012, the limiting groove 204 limits the connecting plate 205, so that the connecting plate 205 can only move and not rotate, thereby preventing the lifting sleeve 201 from rotating. A T-slot 2011 is provided at the bottom of the connecting plate 205, and a T-block 2010 is slidably disposed on the inner wall of the T-slot 2011. A stamping plate 207 is fixedly installed at the bottom of the T-block 2010. The T-slot 2011 and the T-block 2010 connect the stamping plate 207 to the connecting plate 205, allowing the stamping plate 207 to move relative to the connecting plate. 205 moves horizontally. Two T-slots 2011 are provided and symmetrically distributed at the bottom of the connecting plate 205. They are used to set multiple sets of T-blocks 2010 to increase the stability of the connection between the stamping plate 207 and the connecting plate 205. A spring 206 is fixedly installed on the right outer wall of the T-block 2010. The right end of the spring 206 is fixedly connected to the inner wall of the T-slot 2011. A triangular plate 208 is provided in contact with the left outer wall of the stamping plate 207. A support rod 209 is fixedly installed on the left outer wall of the triangular plate 208. One left end of the support rod 209 is fixedly connected to the inner wall of the outer casing 1. 9. Fix the triangular plate 208. The left side of the stamping plate 207 is an arc-shaped surface. The side of the triangular plate 208 that contacts the stamping plate 207 is an inclined surface. When the stamping plate 207 moves downward, it will be resisted by the inclined surface on the triangular plate 208 and move to the right. The spring 206 pushes the T-block 2010 to the left, thereby pushing the stamping plate 207 to the left. This ensures that the left side of the stamping plate 207 is always in contact with the inclined surface on the triangular plate 208. The stamping plate 207 is located directly above the conveyor belt 4. When the stamping plate 207 moves downward, it can press the chain 5 on the conveyor belt 4 and press the locking piece into the chain 5.

[0030] A limiting mechanism 3 is fixedly installed on the right outer wall of the outer casing 1, and a buffer mechanism 6 is provided below the conveyor belt 4;

[0031] The servo motor 2012 is activated, driving the reciprocating screw 202 to rotate. The rotation of the reciprocating screw 202 causes the lifting sleeve 201 to move downwards, which in turn causes the connecting plate 205 to move downwards. The downward movement of the connecting plate 205, through the T-slot 2011 and T-block 2010, causes the stamping plate 207 to move downwards. As the stamping plate 207 moves downwards, the triangular plate 208 abuts against the stamping plate 207 and moves to the right, causing the stamping plate 207 to move downwards and to the right simultaneously. Adjusting the rotation speed of the servo motor 2012 ensures that the stamping plate 207... The chain 5 on the conveyor belt 4 maintains the same speed in the horizontal direction, which avoids the speed difference between the stamping plate 207 and the chain 5, which would cause the locking plate to misalign with the chain 5. When the reciprocating screw 202 drives the lifting sleeve 201 to move upward, it in turn drives the connecting plate 205 and the stamping plate 207 to move upward. As the stamping plate 207 moves upward, the spring 206 pushes the T-block 2010 to move to the right, which in turn pushes the stamping plate 207 to the left, so that the left side of the stamping plate 207 is always in contact with the upper inclined surface of the triangular plate 208.

[0032] In this embodiment, a control panel 9 is fixedly installed on the front of the outer casing 1. The control panel 9 is used to adjust the servo motor 2012 and its rotation speed, as well as the conveying speed of the conveyor belt 4. An observation window 10 is fixedly installed on the front of the outer casing 1 to observe the assembly status inside the outer casing 1.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the assembly equipment for chain processing provided by the present invention is as follows: Figures 1 to 6As shown: The buffer mechanism 6 includes a fixed base 601, a damper 606 fixedly installed on the inner wall of the bottom of the fixed base 601, a lifting column 603 fixedly installed on the top of the damper 606, and a support plate 602 fixedly installed on the top of the lifting column 603. The support plate 602 supports the conveyor belt 4 to prevent the conveyor belt 4 from being damaged by excessive compression when the stamping plate 207 presses down. The damper 606 dampens the impact on the support plate 602 and the lifting column 603. A groove 604 is opened on the outer side wall of the lifting column 603. A slider 605 is slidably arranged on the inner wall of the groove 604. The outer wall of the slider 605 is fixedly connected to the inner wall of the fixed base 601. The slider 605 and the groove 604 are arranged in a way that... 04. Limit the lifting column 603 to prevent it from detaching completely from the fixed base 601. Six dampers 606 are provided and evenly distributed at the bottom of the lifting column 603, which makes the damper 606 have a stronger shock absorption effect on the lifting column 603 and the support plate 602, and prevents the lifting column 603 and the support plate 602 from tilting. The support plate 602 is a rubber plate to prevent damage to rigid materials when the kinetic energy of the pressing plate 207 is repeatedly transmitted downward. When the pressing plate 207 presses down to press the chain 5, the excess kinetic energy is transmitted to the support plate 602 and the lifting column 603 through the conveyor belt 4. At this time, the damper 606 is squeezed downward, converting the kinetic energy into heat energy, completing the shock absorption and preventing damage to the conveyor belt 4.

[0035] Example 3

[0036] Based on Example 1, a preferred embodiment of the assembly equipment for chain processing provided by the present invention is as follows: Figures 1 to 6As shown: The limiting mechanism 3 includes a fixed box 301. The left outer wall of the fixed box 301 is fixedly connected to the right outer wall of the outer shell 1. A bidirectional threaded rod 305 is rotatably connected to the front of the fixed box 301 via a bearing. A clamping plate 302 is threadedly connected to a section of the outer wall of the bidirectional threaded rod 305 inside the fixed box 301. The clamping plate 302 movably passes through the outer wall of the fixed box 301 and the outer shell 1. The clamping plate 302 is located on both sides of the chain 5. A turntable 303 is fixedly installed on the front end of the bidirectional threaded rod 305. A handle 304 is fixedly installed on the front of the turntable 303. The clamping plate 302 limits the two sides of the chain 5 to prevent the chain 5 from running off-center on the conveyor belt 4. The bidirectional threaded rod 305 is designed so that when the bidirectional threaded rod 305 is rotated, the clamping plate 302 moves, changing the position of the two clamping plates. The spacing between the two clamping plates 302 limits the movement of chains 5 of different sizes. A throttle 304 and a turntable 303 are provided for rotating the bidirectional threaded rod 305. The outer wall of the throttle 304 is fixedly fitted with an anti-slip sleeve 7 to facilitate the user's rotation of the throttle 304. A smooth plate 8 is fixedly installed on the outer wall of the clamping plate 302. The outer wall of the smooth plate 8 contacts the outer wall of the chain 5. The smooth plate 8 is provided to prevent friction between the clamping plate 302 and the chain 5, which would prevent the chain 5 from maintaining the same speed as the conveyor belt 4. According to the size of the chain 5, rotating the throttle 304 drives the turntable 303 to rotate, which in turn drives the bidirectional threaded rod 305 to rotate. The rotation of the bidirectional threaded rod 305 causes the two clamping plates 302 to move in opposite directions, changing the spacing between the two clamping plates 302 and limiting the movement of chains 5 of different sizes.
