Description

Technical Field

[0001] The utility model belongs to the technical field of machining equipment, and particularly relates to an inner chamfering processing device for a plastic pipe joint. Background Art

[0002] Plastic pipe joints are mainly used to connect two plastic pipes to achieve a longer transmission distance. The connection end of the traditional plastic pipe joint is a flat end. When the end of the plastic pipe is inserted into the inner wall of the plastic pipe joint for connection, since the plastic pipe and the plastic pipe joint need to be sealed after connection, the outer diameter of the plastic pipe and the inner diameter of the plastic pipe joint adopt an interference fit. It is not easy for the plastic pipe to be directly inserted into the plastic pipe joint. It is necessary to use a hot melt device to heat and soften the connection ends of the plastic pipe and the plastic pipe joint, and then butt the two.

[0003] In the prior art, in order to enable the plastic pipe and the plastic pipe joint to be quickly connected, the connection end of the plastic pipe joint is provided with an inner chamfer structure. Through the guiding action of the inner chamfer, it is easier for the plastic pipe to be inserted into the plastic pipe joint to achieve the quick connection of the two. However, the wall thickness of the inner chamfer structure in the plastic pipe joint is relatively thin, and it is easy to have product defects during the injection molding with the plastic pipe joint. Therefore, it is very difficult to be injection molded in one time by injection molding. It is necessary to form a traditional plastic pipe joint by injection molding, and then obtain the inner chamfer structure by secondary processing at the connection end of the plastic pipe joint. It is necessary to provide an inner chamfering processing device for the plastic pipe joint. Summary of the Utility Model

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them.

[0023] Such as Figures 1 to 6As shown in the figure, this embodiment discloses an internal chamfering processing device for a plastic pipe joint, which includes a control cabinet 1, a machine table 2, a processing cover 3, a clamping mechanism 4 for fixedly clamping the plastic pipe joint, and a milling mechanism 6 for performing internal chamfering milling on the connecting end of the plastic pipe joint. The clamping mechanism 4 and the milling mechanism 6 are relatively installed on the machine table 2. The processing cover 3 is movably connected to the machine table 2. When the processing cover 3 is in the closed state, both the clamping mechanism 4 and the milling mechanism 6 are covered inside the processing cover 3; when the processing cover 3 is in the open state, both the clamping mechanism 4 and the milling mechanism 6 are exposed. The control cabinet 1 is electrically connected to the clamping mechanism 4 and the milling mechanism 6 and is used to control the operation of the clamping mechanism 4 and the milling mechanism 6. A collection hopper 7 for collecting milling waste is provided at the bottom of the machine table 2, and a waste loading cart 5 is provided below the collection hopper 7. During the processing of the plastic pipe joint, milling waste will be generated, and under the action of the processing cover 3, these milling wastes can effectively prevent the milling waste from flying everywhere and finally fall onto the collection hopper 7, and are collected by the collection hopper 7 and enter the waste loading cart 5.

[0024] In this embodiment, there are two milling mechanisms 6 and one clamping mechanism 4. The two milling mechanisms 6 are respectively installed on the left and right sides of the machine table 2 relatively, and the two milling mechanisms 6 are arranged in a staggered manner in the front-rear direction. The clamping mechanism 4 is installed between the two milling mechanisms 6. The clamping mechanism 4 includes a fixture assembly 41, a left-right moving assembly 42 and a front-rear moving assembly 43. The front-rear moving assembly 43 is installed on the machine table 2, the left-right moving assembly 42 is installed on the front-rear moving assembly 43, the fixture assembly 41 is installed on the left-right moving assembly 42, and the fixture assembly 41 is provided with a clamping position 44 for fixedly clamping the plastic pipe joint. When performing the internal chamfering processing on the plastic pipe joint, it is only necessary to fixedly clamp the plastic pipe joint into the clamping position 44. The front-rear moving assembly 43 first drives the left-right moving assembly 42, the fixture assembly 41 and the plastic pipe joint to move to a position coaxial with the milling mechanism 6 near one end of the plastic pipe joint to be processed, and then drives the fixture assembly 41 and the plastic pipe joint to move close to the milling mechanism 6 through the left-right moving assembly 42. When the plastic pipe joint contacts the milling mechanism 6, the milling mechanism 6 processes an internal chamfer at the connecting end of the plastic pipe joint; after one end is processed, the left-right moving assembly 42 drives the fixture assembly 41 and the plastic pipe joint to withdraw from this milling mechanism 6; the front-rear moving assembly 43 drives the left-right moving assembly 42, the fixture assembly 41 and the plastic pipe joint to move to a position coaxial with the other milling mechanism 6 near the other end of the plastic pipe joint to be processed, and then drives the fixture assembly 41 and the plastic pipe joint to move close to the other milling mechanism 6 through the left-right moving assembly 42. When the plastic pipe joint contacts the other milling mechanism 6, the milling mechanism 6 processes an internal chamfer at the other connecting end of the plastic pipe joint; thus, internal chamfers are processed at both connecting ends of the plastic pipe joint. The above layout of the milling mechanism 6 and the clamping mechanism 4 is the layout adopted when processing the plastic pipe joint with a straight-through structure. When the plastic pipe joint is of other structures such as a bent pipe, a tee or a cross, appropriate transformations can be made to achieve the corresponding technical effects, which will not be described in detail here. Preferably, both the left-right moving assembly 42 and the front-rear moving assembly 43 adopt a lead screw-nut transmission mechanism.

[0025] In this embodiment, the fixture assembly 41 includes a fixed clamping block 411 and a movable clamping block 412 disposed within the clamping position 44. The fixed clamping block 411 is fixed to the bottom of the clamping position 44, and the movable clamping block 412 is movably installed at the top of the clamping position 44. The movable clamping block 412 is connected to a locking bolt 413 for adjusting the vertical position of the movable clamping block 412. After the plastic pipe joint is placed in the clamping position 44, the movable clamping block 412 is firmly abutted against the outer wall of the plastic pipe joint through the locking bolt 413, so that the plastic pipe joint is fixed within the clamping position 44. After the plastic pipe joint is processed, the movable clamping block 412 is disengaged from the plastic pipe joint through the locking bolt 413, so that the plastic pipe joint can be removed from the clamping position 44. Further, the fixture assembly 41 includes a base 414, a lower clamping bracket 415, an upper clamping bracket 416, and an adjustment knob 417. The lower clamping bracket 415 is movably installed on the base 414. The lower clamping bracket 415 and the upper clamping bracket 416 are connected to form the clamping position 44. The fixed clamping block 411 is installed inside the lower clamping bracket 415, and the movable clamping block 412 is installed inside the upper clamping bracket 416. The adjustment knob 417 is movably installed in the base 414. A stud 418 threadedly connected to the adjustment knob 417 is provided at the bottom of the lower clamping bracket 415. The lower clamping bracket 415 moves up and down relative to the base 414 based on the rotation of the adjustment knob 417 along the stud 418. When processing plastic pipe joints with different diameters, the height of the fixture assembly 41 can be adjusted by the adjustment knob 417, so that the processing equipment can be applicable to the processing of plastic pipe joints with more diameters. The processing equipment of this embodiment is applicable to the processing of a large number of plastic pipe joints of the same specification. Therefore, during the processing, there is basically no need for large-scale height adjustment. Therefore, during the processing, the adjustment knob 417 only needs to be applicable to achieve fine adjustment in height to meet the errors caused by factors such as mechanical vibration and manual external force during loading and unloading in large-scale processing for adjustment of the fixture assembly 41. When the diameter difference of the plastic pipe joints is relatively large, the entire fixture assembly 41 and the corresponding processing program are directly replaced.

[0026] In this embodiment, the milling mechanism 6 includes a chamfer milling drill bit 61, a chuck 62 and a driving mechanism. One end of the chamfer milling drill bit 61 is fixedly clamped to the chuck 62, and the other end of the chamfer milling drill bit 61 extends axially away from the chuck 62. A chamfer machining edge 64 is provided at the other end of the chamfer milling drill bit 61. The chuck 62 is connected to the driving mechanism. When the milling mechanism 6 works, the driving mechanism drives the chuck 62 to rotate, and the chuck 62 drives the chamfer milling drill bit 61 to rotate. When the plastic pipe joint contacts the chamfer milling drill bit 61, the chamfer machining edge 64 on the chamfer milling drill bit 61 mills the plastic pipe joint to form an internal chamfer. Further, the driving mechanism includes a rotating main shaft 631, a gearbox 632 and a motor 633. The motor 633 is connected to the input shaft of the gearbox 632. A first pulley 634 is connected to the output shaft of the gearbox 632. A second pulley 635 is sleeved outside the rotating main shaft 631. The first pulley 634 and the second pulley 635 are connected by a transmission belt 636. When the motor 633 rotates, it is transmitted through the gearbox 632, the first pulley 634, the transmission belt 636 and the second pulley 635 in sequence, so as to drive the rotating main shaft 631 to rotate.

[0027] The above are only the preferred embodiments of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
