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 shaft groove anti-collision. 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.

[0035] Optionally, there are two support rods 102 .
[0036] Optionally, a sensor is further included. The sensor is arranged on a side of the housing 10 away from the motor 11. When the sensor senses that the slide 12 passes by, the motor 11 is notified to stop rotating.

[0053] Optionally, the worm 13 stops rotating and then rotates in the reverse direction, ie, clockwise.
[0054] Optionally, since the worm 13 rotates counterclockwise, it will drive all the slides 12 to move synchronously along the corresponding spiral track 132 toward the track head 133. Therefore, a first anti-collision member 135 can be set at the track head 133 of any spiral track 132 to achieve the technical effect of preventing all the slides 12 from colliding with the track head 133.

[0064] 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 .
[0065] 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.
