Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of worm pitch-changing modules, and in particular relates to a worm pitch-changing module with an anti-collision slide table. Background Art
[0002] With the increasing development of mechanized production, the use of automated production equipment has become universal. In the process of automated production, it often happens that the storage distance requirements for products are inconsistent in different processing steps of products. The worm pitch module is widely used to solve this problem due to its mature technology, low cost, and precise and controllable displacement.
[0003] The worm pitch change module changes the distance of the product carried on it by processing a spiral track on the worm. In order to smoothly transmit the product, most worm torque conversion modules need to use a slide to support the product for transmission. In order to increase the controllability of the worm torque conversion transmission, the slide often needs to move in the spiral track through a guide column. In order to ensure the rigidity of the guide column and the worm, generally, the guide column and the worm are made of metal materials. Once a collision occurs between the guide column and the spiral track, the spiral track and the guide column are easily deformed, resulting in transmission deviation of the worm torque conversion module.
[0004] Since the guide post is in direct contact with the spiral track, when the worm torque converter module is currently working, the guide post and the end of the spiral track are prone to collision, which greatly increases the maintenance cost of the worm torque converter module. Utility Model Content
[0005] In order to solve the problems raised in the above background technology, the utility model provides a worm pitch changing module with an anti-collision slide, which has the characteristics of simple structure, stable operation, and effective avoidance of collision between the guide column and the end of the spiral track.
[0006] To achieve the above-mentioned purpose, the utility model provides a worm gear pitch change module with an anti-collision slide, including a worm, a first slide and a first limiting mechanism, the first slide includes an anti-collision column, the first limiting mechanism includes a first limiting column, the worm rotates counterclockwise, driving the first slide to move along a spiral track provided on the worm, the first slide moves to a first preset position, and the anti-collision column contacts the first limiting column.
[0007] As a further description of the above technical solution: it also includes a second limiting mechanism, the second limiting mechanism is provided with a second limiting column, the worm rotates clockwise, driving the first slide to move along the spiral track provided on the worm, the first slide moves to the second preset position, and the anti-collision column contacts the second limiting column.
[0008] As a further description of the above technical solution: an elastic buffer structure is provided at the end of the first limiting column.
[0009] As a further description of the above technical solution: an elastic buffer structure is provided at the end of the second limiting column.
[0010] As a further description of the above technical solution: the first slide is a U-shaped structure.
[0011] As a further description of the above technical solution: the first slide is an L-shaped structure.

[0013] As a further description of the above technical solution: the first slide also includes a first positioning column and a first guide column, and the first slide moves along a spiral track arranged on the worm through the first guide column.
[0014] As a further description of the above technical solution: it also includes a sensor.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model arranges an anti-collision column on the first slide, and arranges a first limiting mechanism and a second limiting mechanism on the left and right sides of the anti-collision column respectively. When the first slide moves to the first preset position, the anti-collision column hits the first limiting column, and when the first slide moves to the second preset position, the anti-collision column hits the second limiting column. It only needs to be arranged that when the anti-collision column hits the first limiting column, the first guide column cannot reach the track head, and when the anti-collision column hits the second limiting column, the first guide column cannot reach the track tail, so that the first guide column can be prevented from colliding with the track head and the track tail, thereby effectively protecting the performance of the spiral track.

[0018] 3. The utility model provides elastic buffer structures at both ends of the first limiting column and the second limiting column, thereby protecting the anti-collision column and further improving the service life of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Optionally, the anti-collision column 173 is integrally formed with the first slide platform 17 .
[0042] In one embodiment, the first slide 17 is extended along the length direction and bent to form an anti-collision column 173 .
[0043] In one embodiment, the sum of the number of the slides 12 and the first slides 17 is equal to the number of the spiral tracks 132 disposed on the worm 13 .
[0044] Specifically, the first slide 17 can be modified by adding an anti-collision column 173 to any slide 12, so it can be directly modified and set on the existing worm pitch change module, which is very convenient and practical to set and has strong compatibility.
[0045] Optionally, it also includes a first limiting mechanism 14 and a second limiting mechanism 15, the first limiting mechanism 14 is arranged on the left side of the first slide 17, and the second limiting mechanism 15 is arranged on the right side of the first slide 17, and the first limiting mechanism 14 and the second limiting mechanism 15 are used to limit the moving distance of the first slide 17 in the left and right directions.
[0046] Optionally, in order to ensure the safety of the worm 13 during operation, a shell 10 is provided outside the worm 13 , and the shell 10 is sleeved on the outside of the worm 13 to wrap the worm 13 .
[0047] Optionally, for ease of disassembly and assembly, the housing 10 further includes an end cover 101 , and the end cover 101 is disposed at an end of the housing 10 away from the motor 11 .

The slide 12 is connected to the support rod 102 and can move relative to the support rod 102. In this arrangement, the slide 21 will be constrained by the support rod 102 and the spiral track 132 at the same time when moving, and the movement is very reliable and accurate. At the same time, when the parameters need to be changed, it is also very convenient to set up.

[0055] For further information, see Figure 2 , the worm 13 is provided with several spiral tracks 132 along the length direction, and the spiral track 132 has a track head 133 and a track tail 134. It is only necessary to set the distance between the track heads 133 and the distance between the track tails 134 as required, and the worm pitch-changing module can change the spacing of the items carried thereon. For example, if a product needs to be transported from point A with a spacing of 10mm to point B with a spacing of 20mm, it can be achieved by only setting the distance between the track heads 133 to 10mm and the distance between the track tails 134 to 20mm. It is also possible to set the overall running distance of the pitch-changing module to A to B, so that the product can be transported from A to B with a variable spacing, and vice versa. With the further deepening of the intelligence and automation of production, the precision requirements for product spacing are becoming higher and higher. For example, spiral tracks 132 with different spacings can be set to realize the transportation of products with different spacings, which is very flexible, convenient and easy to set.
[0056] For further information, please refer to Figure 3 The first limiting mechanism 14 further includes a first limiting column 141 and a first limiting block 143 .

[0058] Optionally, an elastic buffer structure is provided at the end of the first limiting column 141 to avoid damage to the anti-collision column 173 due to the influence of instantaneous impact force when contacting the anti-collision column 173.
[0059] Optionally, elastic buffer structures are provided at both axial ends of the first limiting column 141 .
[0060] Optional, please also see Figure 4 The second limiting mechanism 15 further includes a second limiting column 151 and a second limiting block 153 . The second limiting block 153 is provided with a second limiting hole 152 . The second limiting column 151 is sleeved in the second limiting hole 152 .
[0061] Optionally, after the second limiting column 151 is sleeved with the second limiting hole 152, the connection with the second limiting hole 152 can be positioned and fastened by bolts respectively, so that the position of the second limiting column 151 in the second limiting hole 152 can be adjusted according to actual usage requirements, which is very flexible and adaptable to various usage scenarios.
[0062] Optionally, an elastic buffer structure is provided at the end of the second limiting column 151 to avoid damage to the anti-collision column 173 due to the influence of instantaneous impact force when contacting the anti-collision column 173.
[0063] Optionally, elastic buffer structures are provided at both axial ends of the second limiting column 151 .
[0064] Optionally, a positioning column 121 is provided on one side of the slide 12 close to the worm 13 , and a guide column 122 is provided on one end of the positioning column 121 close to the worm 13 , and the slide 12 can move along the corresponding spiral track 132 through the guide column 122 .
[0065] Optionally, the guide column 122 is made of metal.
[0066] Optionally, the motor 11 rotates, driving the worm 13 to rotate, and the slide 12 moves along the spiral track 132 through the guide column 122 .
[0067] Optionally, a first positioning column 171 is provided on one side of the first slide 17 close to the worm 13 , and a first guide column 172 is provided on one end of the first positioning column 171 close to the worm 13 . The first slide 17 can move along the spiral track 132 via the first guide column 172 .
[0068] Optionally, the first guide column 172 is made of metal.
[0069] Optionally, the motor 11 rotates to drive the worm 13 to rotate, and the first slide 17 moves along the corresponding spiral track 132 through the first guide column 172 .
[0070] In one embodiment, the motor 11 rotates counterclockwise, driving the worm 13 to rotate counterclockwise synchronously. The worm 13 drives the first slide 17 to move toward the rail head 133 . The first slide 17 moves to the first preset position, and the anti-collision column 173 contacts the first limit column 141 .
[0071] At this time, it is only necessary to set the anti-collision column 173 to abut against the first limiting column 141 so that the first guide column 172 cannot reach the rail head 133, thereby achieving the technical effect of preventing the first guide column 172 and the rail head 133 from colliding.
[0072] In another embodiment, the worm 13 rotates clockwise to drive the first slide 17 to move toward the track tail 134 , and the first slide 17 moves to the second preset position, and the anti-collision column 173 abuts against the second limit column 151 .
[0073] At this time, it is only necessary to set the first guide column 172 to be unable to reach the track tail 134 when the anti-collision column 173 contacts the second limiting column 151, so as to achieve the technical effect of preventing the first guide column 172 and the track tail 134 from colliding.
[0074] Furthermore, when the worm 13 rotates, since the first slide 17 and all slides 12 will move synchronously, as long as the first guide post 172 is set to be unable to reach the rail head 133, all guide posts 122 will be unable to reach the corresponding rail head 133.
[0075] Similarly, it is only necessary to set the first guide post 172 to be unable to reach the track tail portion 134 , and then all guide posts 122 will be unable to reach the corresponding track head portion 133 .
[0076] Optionally, since the guide column 122 cannot contact the rail head 133 and the rail tail 134 during operation, when setting, the length of the spiral rail 132 needs to have sufficient margin. At the same time, the distance between the rail heads 133 and the distance between the rail tails 134 also need to have a design margin, that is, the distance between the rail heads 133 needs to be smaller than the actual requirement, and the distance between the rail tails 134 needs to be larger than the actual requirement.
[0077] The utility model arranges an anti-collision column 173 on the first slide 17, and arranges a first limiting mechanism 14 and a second limiting mechanism 15 on the left and right sides of the anti-collision column 173 respectively. When the first slide 17 moves to the first preset position, the anti-collision column 173 abuts against the first limiting column 141, and when the first slide 17 moves to the second preset position, the anti-collision column 173 abuts against the second limiting column 151. It is only necessary to respectively arrange that when the anti-collision column 173 abuts against the first limiting column 141, the first guide column 172 cannot reach the rail head 133, and when the anti-collision column 173 abuts against the second limiting column 151, the first guide column 172 cannot reach the rail tail 134, so as to avoid the first guide column 172 from colliding with the rail head 133 and the rail tail 134, thereby effectively protecting the performance of the spiral rail 132.
[0078] At the same time, since the first slide 17 moves synchronously with the slide 12, the first slide 17 can also be used to transport products. The first slide 17 can also be directly modified from any slide 12, so it will not affect the operating efficiency of the worm pitch change module.
[0079] At the same time, elastic buffer structures are provided at both ends of the first limiting column 141 and both ends of the second limiting column 151 to protect the anti-collision column 173 and further improve the service life of the utility model.
[0080] The utility model has the characteristics of simple structure, stable operation, and effective avoidance of collision between the guide column 122 and the end of the spiral track 132, and can effectively extend the service life of the worm pitch change module and reduce the maintenance cost of the worm torque change module.
