Technical Field

[0001] This utility model relates to the field of plastic pipe processing equipment, specifically a multi-station assembly mechanism for plastic core tubes. Background Technology

[0002] Plastic core tubes are a type of plastic pipe. After molding and cutting, they need to be press-fitted together with a tube seat. The tube seat has a through hole in the center, and its overall shape can be regarded as rectangular. During the assembly process, the core tube needs to be press-fitted into the through hole of the tube seat.

[0003] Existing core tube assembly equipment uses simple pneumatic cylinders or electric actuators to complete a single pressing at one station. The existing assembly method may produce defective products with broken core tubes, and the positioning and guiding effect of the assembly is poor, resulting in a low yield. Therefore, a multi-station assembly mechanism for plastic core tubes is needed. Utility Model Content

A baffle is slidably connected in the second positioning groove. The piston rod of the assembly cylinder is fixedly connected to the baffle. Multiple positioning components are provided on the baffle, and each positioning component includes a positioning shaft, a guide post, and a spring.

[0006] Furthermore, the first positioning seat, the second positioning seat, and the assembly cylinder are all fixedly connected to the base. There are multiple first positioning slots, and the multiple first positioning slots are arranged in a linear array on the first positioning seat.

[0007] Furthermore, the limiting block includes a bracket and a limiting rod, the limiting rod being rotatably connected to the bracket, and the bracket being fixedly connected to the piston rod of the limiting cylinder.

[0008] Furthermore, the positioning shaft is slidably connected to the baffle, the guide post is fixedly connected to the positioning shaft, the guide post and the positioning shaft are slidably connected to the baffle, and the spring is located between the positioning shaft and the baffle.

[0009] Furthermore, the positioning shaft has multiple adsorption holes on its sidewall, and these adsorption holes are arranged in a ring array on the positioning shaft.

[0010] Furthermore, the cross-section of the first positioning groove is U-shaped.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] Please see Figure 1-4The multi-station assembly mechanism for plastic core tubes shown includes a base 1, on which a first positioning seat 2 and a second positioning seat 3 are arranged in parallel. An assembly cylinder 4 is fixedly connected to the base 1. A first positioning groove 201 is opened on the first positioning seat 2, and a second positioning groove 301 is opened on the second positioning seat 3. A limit cylinder 5 is fixedly connected to the lower part of the first positioning seat 2. A limit block 6 is fixedly connected to the piston rod of the limit cylinder 5. A baffle 7 is slidably connected in the second positioning groove 301. The piston rod of the assembly cylinder 4 is fixedly connected to the baffle 7. Multiple positioning components are provided on the baffle 7. The positioning components include a positioning shaft 801, a guide post 802, and a spring 803.

[0021] The first positioning seat 2, the second positioning seat 3 and the assembly cylinder 4 are all fixedly connected to the base 1. There are multiple first positioning slots 201 on the first positioning seat, and multiple core tubes can be positioned and placed on the first positioning seat 2 at the same time.

[0022] The limiting block 6 includes a bracket and a limiting rod. The limiting rod is rotatably connected to the bracket. The limiting cylinder 5 is used to drive the limiting block 6 to perform translational movements. During assembly processing, the limiting rod can limit the plastic core tube.

[0023] The positioning shaft 801 is slidably connected to the baffle 7. During the assembly process, the baffle 7 guides the translation and sliding of the positioning shaft 801. The guide post 802 is fixedly connected to the positioning shaft 801. The guide post 802 and the positioning shaft 801 are slidably connected to the baffle 7. The spring 803 is placed between the positioning shaft 801 and the baffle 7. The spring 803 is used to reset the positioning shaft 801.

[0024] Multiple adsorption holes 8011 are opened on the side wall of the positioning shaft 801, and the multiple adsorption holes 8011 are arranged in a ring array on the positioning shaft 801. After the tube seat is placed, the adsorption holes 8011 adsorb and fix the tube seat 10 to prevent the tube seat 10 from falling off during the assembly process.

[0025] A positioning post 9 is fixedly connected to each positioning component on the baffle 7. When positioning the tube seat 10, the positioning post 9 can be inserted into the through hole on the tube seat 10 to further position the tube seat.

[0026] The working principle of this utility model is as follows: When using this utility model, the core tube 11 is placed in the first positioning groove 201 along the limiting rod. Then, the tube seat 10 to be assembled is placed along the second positioning groove 301, the positioning shaft 801 and the positioning post 9 and placed against the baffle 7. Then, the tube seat 10 is attracted by the suction hole 8011 to prevent it from falling off. Then, the assembly action is performed. The piston rod of the assembly cylinder 4 extends, and the baffle 7 slides towards the first positioning seat 2. During the sliding process, the positioning shaft 801 will contact the core tube 11. Under the action of the core tube 11, the positioning shaft 801 will slide away from the first positioning seat 2 relative to the baffle 7 until the core tube 11 is completely pressed into the through hole of the tube seat 10. The assembly is then completed. After the piston rod of the assembly cylinder 4 is reset, the piston rod of the limiting cylinder 5 extends, and the limiting block 6 is moved away from the first positioning groove 201. The assembled finished product can then be unloaded.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
