Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting machine clamps, in particular to a positioning clamping component for cutting PE pipes. Background Art

[0002] When the pipe cutting machine's blade cuts PE pipes, since the PE pipe material is relatively soft, when the blade cutting speed is slow or the blade is not sharp enough, the pipe material will be cut, causing part of the material to be pulled and torn, and then fall off in the form of debris, rather than breaking cleanly. When current pipe cutting machines cut PE pipes, in order to ensure that the pipes will not move or twist during the cutting process, they generally use clamps to fix the PE pipes first.

[0003] The current technical problem is that a large amount of debris will be generated during cutting, and the PE pipe debris will be partially melted due to the temperature generated by the friction of the blade during cutting, and then adhere to the clamp, causing the clamp to be blocked. Therefore, the clamp cannot fit the PE pipe well, resulting in unstable fixation. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a positioning clamping assembly for PE pipe cutting to solve the technical problem that the existing PE pipe cutting clamp is prone to debris adhesion, resulting in a decrease in the clamping effect of the clamp.

[0005] Based on the above objectives, the utility model provides a positioning clamping assembly for cutting PE pipes, comprising:

[0006] At least two clamping blocks with clamping grooves;

[0007] A driving structure for driving the two clamping blocks to merge or separate;

[0008] Cleaning parts for cleaning the outer surface of PE pipes;

[0009] A linkage component is provided between the two clamping blocks and connected to the cleaning member, and is used for driving the cleaning member to fit the PE pipe when the two clamping blocks are separated from the PE pipe.

[0010] As a preferred technical solution of the present utility model, the linkage component includes:

[0012] A second driving member is movably hinged at one end to the other clamping block, the other ends of the first driving member and the second driving member are hinged to each other, and the cleaning member is movably connected to the first driving member or the second driving member. As the two clamping blocks are separated, the first driving member and the second driving member will swing around the clamping block, thereby making the cleaning member fit the PE pipe through the swinging.

[0013] As a preferred technical solution of the present invention, both the first driving member and the second driving member are provided with a rotating shaft, and the rotating shaft is rotatably engaged with a rotating groove provided in the clamping block.

[0014] As an optimal technical solution of the present invention, the clamping assembly also includes a connecting rod for connecting the first driving member and the cleaning member, the first driving member is provided with a through groove, a first fixed shaft is provided in the through groove, the first fixed shaft is sleeved with one end of the connecting rod, the cleaning member is provided with a second fixed shaft, and the second fixed shaft is sleeved with the other end of the connecting rod.

[0015] As a preferred technical solution of the present utility model, the cleaning element includes:

[0016] a movable plate connected to the second fixed shaft;

[0017] Brush bristles are arranged on the side of the movable plate facing the PE tube.

[0018] As a preferred technical solution of the present utility model, the driving structure includes:

[0019] a slider connected to the clamping block;

[0020] A slide rail adapted to the slider;

[0021] A bidirectional screw rod is rotatably arranged in the slideway of the slide rail at one end, and the bidirectional screw rod is matched with a screw rod groove provided in the slider;

[0024] As a preferred technical solution of the present invention, there are at least two movable plates, and the movable plates are symmetrically arranged about the center of the clamping groove.

[0025] As a preferred technical solution of the present invention, the clamping assembly further comprises: a platform and a conveying roller provided on the platform, wherein the conveying roller is used to feed the PE pipe into the clamping groove of the clamping block for fixation.

[0026] As a preferred technical solution of the present invention, there are multiple conveying rollers, and the conveying rollers are arranged on the front and rear sides of the clamping block.

[0027] The beneficial effects of the present invention are as follows: the present invention provides a cleaning piece. After the PE pipe is cut, as the clamping blocks separate from each other, the cleaning piece can be driven by the linkage component to fit the pipe fitting, and the clamping groove of the clamping block is separated from the PE pipe.

[0036] like Figure 1 As shown, a positioning clamping assembly for cutting a PE pipe comprises:

[0037] At least two clamping blocks 6 with clamping grooves 7;

[0038] A driving structure for driving the two clamping blocks 6 to merge or separate;

[0039] A cleaning piece for cleaning the outer surface of the PE pipe 3;

[0040] A linkage component is provided between the two clamping blocks 6 and connected to the cleaning member, and is used to drive the cleaning member to fit the PE tube 3 when the two clamping blocks 6 are separated from the PE tube 3;

[0041] The above technical solution can clean the debris on the outer surface of the PE tube 3 after it is cut. When in use, the PE tube 3 is placed between the clamping grooves 7 of the two clamping blocks 6, and the driving structure is started to drive the two clamping blocks 6 to merge with each other, thereby clamping the PE tube 3. The blade of the pipe cutter cuts the PE tube 3, and a large amount of debris is generated during cutting. When the cutting is completed, the clamping blocks 6 are separated from each other, and the cleaning piece can be driven by the linkage component to fit the PE tube 3, and the clamping groove 7 of the clamping block 6 is separated from the PE tube 3. The subsequent PE tube 3 will rub against the cleaning piece as the pipe cutter feeds, thereby cleaning off the debris attached to the surface of the PE tube 3, preventing the debris from adhering to the clamping groove 7 of the clamping block 6, and avoiding affecting the clamping effect of the clamping block 6 on the subsequent PE tube 3.

[0042] like Figure 2 and Figure 3As shown, in this embodiment, the linkage components include: a first driving member 8 movably hinged to one of the clamping blocks 6 at one end; a second driving member 9 movably hinged to the other clamping block 6 at one end; the other ends of the first driving member 8 and the second driving member 9 are hinged to each other; the cleaning member is movably connected to the first driving member 8 or the second driving member 9; as the two clamping blocks 6 separate, the first driving member 8 and the second driving member 9 swing around the clamping block 6, thereby causing the cleaning member to fit the PE pipe 3 through the swinging; the first driving member 8 and the second driving member 9 are both provided with a rotating shaft 16, which is rotatably engaged with a rotating groove 17 provided in the clamping block 6;

[0043] The above technical solution can drive the cleaning member to move by merging or separating the clamping blocks 6. When the two clamping blocks 6 merge with each other, the angle between the first driving member 8 and the second driving member 9 is at the minimum state. As the two clamping blocks 6 separate, the angle gradually increases and can reach a flat angle at most. During this change process, the swing of the first driving member 8 and the second driving member 9 will cause the cleaning member to gradually move toward the PE tube 3 until it contacts the PE tube 3. As the pipe cutting machine feeds, the cut PE tube 3 is ejected from the clamping groove 7 of the clamping block 6, and the new part of the PE tube 3 is inserted into the clamping groove 7 of the clamping block 6. During this process, the cleaning member rubs against the PE tube 3, thereby cleaning the debris on the surface of the PE tube 3 and preventing the debris from adhering to the clamping groove 7 or the surface of the PE tube 3 and affecting the clamping. As the driving structure drives the two clamping blocks 6 to merge with each other, thereby clamping the PE tube 3, the angle between the first driving member 8 and the second driving member 9 is at the minimum state, and the cleaning member is away from the PE tube 3.

[0044] like Figure 4 As shown, in this embodiment, the clamping assembly further includes a connecting rod 12 for connecting the first driving member 8 and the cleaning member. The first driving member 8 is provided with a through slot 10, and a first fixed shaft 11 is provided in the through slot 10. The first fixed shaft 11 is sleeved with one end of the connecting rod 12. The cleaning member is provided with a second fixed shaft 14, and the second fixed shaft 14 is sleeved with the other end of the connecting rod 12.

[0045] By adopting the above technical solution, the cleaning member can be driven to move by the swing of the first driving member 8, and the first driving member 8 and the cleaning member can be connected by transmission by providing the connecting rod 12.

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the cleaning member includes: a movable plate 13 connected to the second fixed shaft 14; bristles 15 provided on the side of the movable plate 13 facing the PE tube 3; the movable plate 13 is an arc-shaped plate, a movable chamber is provided inside the clamping block 6, the movable plate 13 is arranged in contact with the movable chamber, and the first driving member 8, the second driving member 9 and the connecting rod 12 are also provided in the movable chamber; there are at least two movable plates 13, and the movable plates 13 are symmetrically arranged about the center of the clamping groove 7;

[0047] The above technical solution can better clean the PE tube 3. Since the cleaning member is arranged inside the clamping block 6, on the one hand, the volume of the device can be reduced and space can be saved. On the other hand, compared with arranging the cleaning member outside, the cleaning member can be prevented from being contaminated by dust and kept clean. At the same time, the cleaning member adopts a movable plate 13 with an arc plate structure, which can better fit the surface of the circular PE tube 3. Since the movable plate 13 fits the movable chamber inside the clamping block 6, it can prevent the movable plate 13 from tilting when sliding, and maintain the stability of the structure. Taking two movable plates 13 as an example, they are arranged inside the clamping block 6 in an upper and lower symmetrical manner. When the movable plates 13 fit each other, the bristles 15 inside the movable plates 13 will completely cover the outer surface of the PE tube 3 to prevent unclean cleaning.

[0048] like Figure 1 and Figure 2 As shown, in this embodiment, the driving structure includes: a slider 5 connected to the clamping block 6; a slide rail 4 adapted to the slider 5; a bidirectional screw 19 with one end rotatingly arranged in the slideway of the slide rail 4, the bidirectional screw 19 cooperating with a screw groove 20 provided in the slider 5; a motor 18 mounted on the slide rail 4, the output shaft of the motor 18 being connected to the other end of the bidirectional screw 19;

[0049] The above technical solution can drive the two clamping blocks 6 to merge or separate with each other. When in use, the starting motor 18 can drive the bidirectional screw 19 to rotate. The bidirectional screw 19 cooperates with the screw groove 20 to drive the two sliders 5 to move toward each other or away from each other along the slide rail 4. The slider 5 is preferably a T-shaped block, and accordingly, the slide track of the slide rail 4 is a T-shaped slide track.

[0050] like Figure 1 As shown, in this embodiment, the clamping assembly further includes: a platform 1 and a conveying roller 2 provided on the platform 1, the conveying roller 2 is used to feed the PE pipe 3 into the clamping groove 7 of the clamping block 6 for fixation; there are multiple conveying rollers 2, and the conveying rollers 2 are arranged on the front and rear sides of the clamping block 6;

[0051] The above technical solution can be used to feed and support the PE pipe 3. In order to prevent debris from entering the slideway of the slide rail 4 and causing obstruction of the movement of the slider 5, a first chip groove is provided at the bottom of the slide rail 4. Correspondingly, a second chip groove is provided at the position corresponding to the first chip groove on the platform 1. When the debris falls into the slideway of the slide rail 4, it will pass through the first chip groove and the second chip groove in turn, and will not accumulate in the slideway of the slide rail 4.

[0052] Working principle: When in use, the conveying roller 2 sends the PE pipe 3 between the clamping grooves 7 of the two clamping blocks 6, and the starting motor 18 drives the bidirectional screw rod 19 to rotate. The bidirectional screw rod 19 cooperates with the screw rod groove 20 to drive the two sliders 5 to move toward each other along the slide rail 4, thereby clamping the PE pipe 3. The blade of the pipe cutter cuts the PE pipe 3, and a large amount of debris is generated during cutting. When the cutting is completed, the motor 18 drives the bidirectional screw rod 19 to reverse so that the clamping blocks 6 move in the direction away from each other. As the two clamping blocks 6 separate, the angle between the first drive member 8 and the second drive member 9 gradually increases, and can reach a flat angle at most. During this change process, the rotating shaft 16 of the first drive member 8 swings and rotates around the rotating groove 17, and the first drive member 8 drives the movable plate through the connecting rod 12 13 and the bristles 15 gradually move toward the PE tube 3 until the bristles 15 touch the PE tube 3. As the conveyor roller 2 of the pipe cutter feeds, the PE tube 3 moves along the conveyor roller 2, and the cut PE tube 3 is ejected from the clamping groove 7 of the clamping block 6, and the new part of the PE tube 3 is inserted into the clamping groove 7 of the clamping block 6. During this process, the cleaning member rubs against the PE tube 3, thereby cleaning the debris on the surface of the PE tube 3 to prevent the debris from adhering to the clamping groove 7 or the surface of the PE tube 3 from affecting the clamping. As the motor 18 drives the two clamping blocks 6 to merge with each other, the PE tube 3 is clamped, and the angle between the first drive member 8 and the second drive member 9 returns to the minimum state, and the cleaning member moves away from the PE tube 3, thereby continuing the next round of cutting.
