Description

Technical Field

[0001] This utility model relates to the field of opening holes in plastic pipes, and in particular to a device for opening holes in plastic pipes. Background Technology

[0002] In the processing of plastic pipes, the hole-drilling operation is a crucial step in realizing their functional applications, widely used in drainage, wiring, ventilation, and other fields. During continuous hole-drilling of plastic pipes, the clamping and positioning of the pipe are critical factors affecting drilling accuracy and processing efficiency. Currently, most hole-drilling equipment uses fixed clamping devices to position and support the plastic pipe. While this type of clamping structure can ensure the stability of the pipe during processing to a certain extent, its fixed structure and lack of flexibility prevent the automatic conveying and rotation adjustment of the pipe. This fixed clamping method means that the plastic pipe can only remain stationary during the hole-drilling process. Adjusting the hole position or achieving different circumferential angles often requires manual intervention or machine shutdown, which not only reduces production efficiency but also fails to meet the demands of continuous and automated processing. Therefore, a new plastic pipe hole-drilling device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0013] Example 1 like Figure 1-11 As shown, a plastic pipe opening device includes a pipe body 4. The opening device includes a base 1. A clamping and adjusting mechanism 2 and an opening mechanism 3 are provided on the top of the base 1. The clamping and adjusting mechanism 2 clamps the pipe body 4 therein and is used to adjust the opening position of the pipe body 4. The opening mechanism 3 is provided at the front end of the clamping and adjusting mechanism 2 and is used to open the pipe body 4.

[0014] With this design, the tube body 4 is clamped onto the base 1 by the clamping and adjusting mechanism 2, and its preset opening position is adjusted to pass through the opening mechanism 3 in sequence, so that the opening mechanism 3 can be used to perform the corresponding opening work at the preset opening position.

[0015] The clamping and adjusting mechanism 2 includes two clamping mechanisms 21, and a rotation and displacement mechanism 22 is provided between the two clamping mechanisms 21.

[0016] The clamping mechanism 21 includes two clamping units 210 arranged symmetrically above and below for clamping the tube body 4. A clamping telescopic cylinder 211 is provided between the two sides of the two clamping units 210. The two clamping units 210 can separate and move closer together by clamping the telescopic cylinder 211, thereby clamping or releasing the tube body 4.

[0017] The clamping unit 210 includes a first support base 2101, on which a support frame 2102 is provided. The top of the support frame 2102 is provided with an arc-shaped groove 2103, which is adapted to the tube body 4 to increase the contact area with the tube body 4. Both sides of the arc-shaped groove 2103 are provided with elastic ball bearing components 2104 adapted to its curvature. The elastic ball bearing components 2104 can extend out of the surface of the arc-shaped groove 2103 to abut against the tube body 4, or they can retract into the surface of the arc-shaped groove 2103.

[0018] With this design, when the two clamping units 210 come together, the pressure can be used to retract the elastic ball component 2104, thereby achieving the effect of clamping the tube body 4 through the upper and lower support frames 2102. In addition, after the two clamping units 210 separate, the tube body 4 can be rotatably and forwardly clamped by the two pop-out elastic ball components 2104, which reduces the friction during rotation and forward movement and prevents it from shifting under the adjustment of the rotation and displacement mechanism 22.

[0019] In a preferred embodiment, the elastic ball bearing component 2104 includes a mounting base 2105 disposed on the first support base 2101. The interior of the mounting base 2105 is hollow, and its top is an opening that matches the curvature of the arc groove 2103. The mounting base 2105 is provided with a plurality of elastic telescopic ball bearings. In this embodiment, the number of elastic telescopic ball bearings is five, and the five elastic telescopic ball bearings are arranged in an arc shape, and the curvature matches the arc groove 2103. Their tops protrude from the opening at the top of the mounting base 2105, thereby adapting to the external shape of the tube body 4.

[0020] Furthermore, the elastic telescopic ball bearing part includes a telescopic seat 2106 movably disposed at the opening of the mounting base 2105. Limiting grooves 2108 are provided on both opposite inner walls of the mounting base 2105. A limiting block 2109 is provided at the bottom of the mounting base 2105, slidingly engaging with the limiting groove 2108. The sliding engagement between the limiting block 2109 and the limiting groove 2108 restricts the telescopic range. A ball bearing 2107 is rotatably disposed at the top of the telescopic seat 2106, extending from the opening of the mounting base 2105. The ball bearing 2107 adheres to the tube body 4, enabling the aforementioned rotatable and forward clamping. A telescopic spring 2110 is provided between the inner bottom wall of the mounting base 2105 and the bottom of the telescopic seat 2106, utilizing the tension of the telescopic spring 2110 to achieve the telescopic movement of the mounting base 2105.

[0021] What is required is that the length of the telescopic spring 2110 needs to meet the requirements of the arc-shaped arrangement of the elastic telescopic ball bearing.

[0022] In a preferred embodiment, the rotation and displacement mechanism 22 includes two support slide rods 220 disposed between the bottoms of the two clamping mechanisms 21. A movable seat 221 is slidably fitted onto the outside of the two support slide rods 220. The movable seat 221 is provided with holes for the support slide rods 220 to pass through. A telescopic cylinder 222 is provided between the movable seat 221 and the clamping mechanism 21 located at the rear end. A rotation clamping mechanism 223 is provided on the top of the movable seat 221.

[0023] This design allows the rotating clamping mechanism 223 to clamp the tube 4, and in conjunction with the telescopic movement of the telescopic cylinder 222, the tube 4 can be moved forward in stages.

[0024] It should be noted that the maximum extension stroke of the telescopic cylinder 222 can push the movable seat 221 and the rotary clamping mechanism 223 to the rear of the front clamping mechanism 21.

[0025] In addition, the rotary clamping mechanism 223 includes an outer ring 2230 disposed on the top of the movable seat 221. A rotating ring 2231 is rotatably disposed on the inner side of the outer ring 2230. A bearing for rotary installation is disposed between the outer ring 2230 and the rotating ring 2231. Both ends of the rotating ring 2231 extend outside the outer ring 2230, and a plurality of clamping components are arranged in a ring on one end. In this embodiment, the number of clamping components is three, which are used to clamp the tube body 4. A driven gear ring 2236 is disposed on the outside of the other end. A rotary drive device 2237 is disposed on the top of the outer ring 2230. A transmission gear 2238 that meshes with the driven gear ring 2236 is disposed on the output end of the rotary drive device 2237.

[0026] With this design, the tube body 4 can be clamped by the clamping assembly, and the rotating ring 2231 can be driven to rotate in the outer ring 2230 by the rotating drive device 2237, thereby adjusting the openings of the tube body 4 at different circumferential angles by rotation.

[0027] The clamping assembly includes an extension platform 2232 disposed at the end of the rotating ring 2231. A second clamping telescopic cylinder 2234 is disposed on the extension platform 2232. The output end of the second clamping telescopic cylinder 2234 passes through the extension platform 2232 and is connected to a clamping part 2235. The inner side of the clamping part 2235 is an arc shape adapted to the tube body 4.

[0028] It should be noted that when the clamping mechanism 21 releases the tube body 4, the tube body 4 will be appropriately lifted a certain distance after the elastic ball component 2104 bounces up. Therefore, the central axis of the rotating ring 2231 is coaxial with the central axis of the tube body 4 that is pushed out after the clamping mechanism 21 is released. At the same time, the contraction of the clamping part 2235 satisfies the displacement distance requirement of the tube body 4 after it is clamped by the clamping mechanism 21.

[0029] In a preferred embodiment, the rotation and displacement mechanism 22 further includes a processing base 23, which is located in front of the clamping unit 210 at the front end. The processing base 23 includes a second support base 230, a processing frame 231 is provided on the top of the second support base 230, a processing groove 232 is provided on the processing frame 231, and a through hole 233 is provided on the processing groove 232 to pass through it.

[0030] In addition, the drilling mechanism 3 includes a gantry 301 mounted on the top of the base 1. A lifting telescopic cylinder 302 is provided on the gantry 301. The telescopic end of the lifting telescopic cylinder 302 passes through the gantry 301 and is equipped with a drilling machine 303. The drill bit of the drilling machine 303 is located directly above the hole 233.

[0031] This design allows the processing frame 231 to provide bottom support for the hole punch 303 during hole punching, preventing the hole from being punched in mid-air. At the same time, the design of the through hole 233 makes it easier for the drill bit of the hole punch 303 to penetrate the pipe body 4.

[0032] It should be noted that the hole punching machine 303 consists of a rotary motor and a drill bit. This is a common commercially available product, so it will not be described in detail here.

[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
