Detailed Embodiments

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] As Figure 1-5 shown, the present application provides a side hole processing device for plastic pipe fittings, including a base 1, on which a chassis 2 is fixedly connected. A turntable 3 is rotatably connected at the center position of the chassis 2. The turntable 3 can rotate freely on the chassis 2, so as to facilitate changing the rotation angle of the plastic pipe.

[0031] As Figure 1 and Figure 2 shown, a side hole processing mechanism 4 is installed on the base 1. The side hole processing mechanism 4 includes a support block 41 fixedly connected to the base 1. A connecting plate 42 is fixedly connected to one side of the support block 41. A hydraulic cylinder 43 is fixedly installed on the connecting plate 42. The output end of the hydraulic cylinder 43 is fixedly connected to a rectangular plate 44. A motor 45 is fixedly connected to the rectangular plate 44 through a fastening bolt. The output end of the motor 45 is fixedly connected to a connecting column 46. A cutter head 47 is clamped inside the connecting column 46. When the motor 45 works, it drives the cutter head 47 to rotate at a high speed. At this time, by rotating the turntable 3, when the turntable 3 rotates, the angle of the plastic pipe fitting on the fixture table 501 relative to the cutter head 47 will also change. At this time, the hydraulic cylinder 43 is pushed to move the motor 45, thereby indirectly driving the cutter head 47 to approach the plastic pipe fitting, realizing the side hole processing of the plastic pipe fitting.

[0032] As Figure 1-5As shown in the figure, a clamping mechanism 5 is installed on the turntable 3. The clamping mechanism 5 includes a fixture table 501 fixedly connected to the turntable 3. A chute 502 is formed on the surface of the fixture table 501. Two movable clamping blocks 503 are slidably connected to the inner wall of the chute 502. A bolt rod a 505 is rotatably connected to the fixture table 501. A double-thread is provided on the arc surface of the bolt rod a 505. The movable clamping blocks 503 are threadedly connected to the bolt rod a 505. An anti-slip sheet 504 is fixedly connected to the surface of the movable clamping blocks 503. One end of the bolt rod a 505 is fixedly connected to a circular sheet 506. A grip 507 is rotatably connected to the circular sheet 506. Before side hole machining, the grip 507 can be rotated. The rotation of the grip 507 will drive the bolt rod a 505 on the circular sheet 506 to rotate. Since the two movable clamping blocks 503 are respectively located at both ends of the bolt rod a 505, at this time, the movable clamping blocks 503 move towards each other under the drive of the bolt rod a 505, so that the two movable clamping blocks 503 will clamp the plastic pipe fitting.

[0033] Two limiting rods 508 are slidably penetrated through one side of the fixture table 501. One end of the limiting rods 508 is fixedly connected to a top plate 511. A scale bar 509 is provided on the surface of the limiting rods 508. A bolt rod b 510 is rotatably connected to the side of the top plate 511 close to the fixture table 501. The bolt rod b 510 is threadedly penetrated through the surface of the fixture table 501. At the same time, when placing the plastic pipe fitting on the fixture table 501, one end of the plastic pipe fitting can be abutted against the top plate 511. When it is necessary to drill a hole at a specific position of the pipeline, the bolt rod b 510 can be rotated to drive the top plate 511 to move, and the drilling position of the plastic pipe fitting can be accurately adjusted according to the scale bar 509.

[0034] When rotating the turntable 3, in order to fix the rotation angle of the turntable, as Figure 5 shown, a bolt rod c 512 is threadedly penetrated through the surface of the turntable 3. One end of the bolt rod c 512 is fixedly connected to a pressing piece 513. The other end of the bolt rod c 512 is fixedly connected to a rotating block 514. By rotating the rotating block 514, it is convenient to rotate the bolt rod c 512 to drive the pressing piece 513 to tightly press the surface of the chassis 2, so as to realize the limit of the turntable 3.

[0035] As Figure 1-5 shown, a replacement mechanism 6 is installed on the tool bit 47. The replacement mechanism 6 includes a plug post 61 fixedly connected to the tool bit 47. A jack 67 is formed at one end of the connecting column 46. The size of the plug post 61 is adapted to the size of the jack 67. Four circular holes 66 are formed on the arc surface of the connecting column 46.

[0036] A fixing rod 62 is fixedly connected to the inner wall of the inserting post 61. Four circular columns 63 are fixedly connected to the arc surface of the fixing rod 62. A telescopic buckle 65 is slidably connected to the surface of the circular column 63. A spring 64 is sleeved on the circular column 63. Two ends of the spring 64 are respectively fixedly connected to the fixing rod 62 and the telescopic buckle 65. The four circular columns 63 are evenly distributed on the arc surface of the connecting rod. The telescopic buckle 65 slidably penetrates through the arc surface of the inserting post 61. The sizes of the telescopic buckle 65 and the circular hole 66 are adapted to each other. The quick replacement of the cutter head 47 is realized through the cooperation of the telescopic buckle 65 and the circular hole 66.

[0037] Working principle: When side holes need to be processed on plastic pipe fittings, personnel can clamp the plastic pipe fittings through two movable clamping blocks 503. The top plate 511 can be adjusted to punch holes at specific positions on the plastic pipe fittings according to the scale bar 509. When starting to punch holes, personnel can rotate the turntable 3. After rotating an appropriate angle, the bolt rod c512 can be rotated to drive the pressing piece 513 to tightly press the chassis 2, so as to limit the rotation angle of the turntable 3. At this time, personnel can start the hydraulic cylinder 43 and the motor 45. Driven by the hydraulic cylinder 43, the cutter head 47 rotating on the driving rod motor 45 approaches the plastic pipe fitting, so as to realize the processing of side holes on the plastic pipe fitting.

[0038] Meanwhile, in order to change the inner diameter of the opened hole to meet the requirements of different scenarios, personnel can press the telescopic buckle 65. When the telescopic buckle 65 is pressed to the bottom end, personnel can directly pull out the cutter head 47 outward. When installing a new cutter head 47, the new cutter head 47 can be directly inserted into the connecting column 46. During the insertion process of the cutter head 47, the telescopic buckle 65 will be squeezed and thus retracted into the inserting post 61. When the cutter head 47 is completely inserted into the connecting column 46, the cutter head 47 can be slightly rotated at this time to align the position of the telescopic buckle 65 with the circular hole 66. Under the action of the elastic force of the spring 64, the telescopic buckle 65 extends out of the circular hole 66, so as to realize the installation of the cutter head 47.

[0039] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
