Description

Technical Field

[0001] The utility model relates to the technical field of flat-mouth machine clamps, in particular to a flat-mouth machine clamp which can process beveled edges. Background Art

[0002] Flattening machine equipment is widely used in the laying, welding and other fields of pipe fittings. Its main function is to flatten the pipe interface after cutting, remove the burrs on the stainless steel pipe mouth, make the pipe mouth smooth, and process it into a weldable incision. It is the key to affecting the quality of the product.

[0003] During the project execution, the welding and installation of pipe fittings generally have certain slope requirements. In the process of pipe fitting welding, in order to achieve the slope required by the process, the slope is often achieved by the stress of the pipe fittings. In this way, the pipe fittings will have certain stress, and problems may occur in the pipe fittings over a long period of time. In order to avoid this stress, the pipe fittings need to grind the elbow or tee interface to achieve a certain slope to achieve the slope requirement. The current method of grinding the elbow or tee interface is to use an angle grinder or hand rubbing to achieve it. In this way, the interface may not be polished flat, which is not conducive to welding, and may also damage the finish of the inner wall of the pipe fitting. In order to avoid this situation, there is a need for a method that can process the interface of the pipe into a surface with a certain angle to the axis of the pipe fitting. The flattening machine currently on the market can only process the interface of the pipe into a surface perpendicular to the axis of the pipe fitting. Based on this background, the development of a flattening machine fixture that can process bevels has become an urgent problem to be solved by technicians in this field.

[0004] The existing patent (publication number: CN 219402542 U) discloses a flattening machine fixture that can process beveled edges. The flattening machine fixture can process the pipe interface into a surface with a certain angle to the pipe axis. The processed pipe is easier to weld and has better quality after welding, avoiding the problem of unevenness and non-standard manual grinding.

[0005] However, the above technical solution still has certain defects. Although the above patent can process the pipe interface into a surface with a certain angle to the pipe axis, the processed pipe is easier to weld and the quality after welding is better, avoiding the problem of unevenness and non-standard manual grinding. However, when the incision of the pipe needs to be cut into an oblique end, the above patent cannot cut the incision of the pipe into an oblique end. For this reason, a flattening machine fixture that can process oblique ends is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A flat-mouth machine fixture that can process beveled edges, such as Figure 1-5 As shown, it includes a flat-mouth machine body 100, a cutter 101 is rotatably connected to the end of the flat-mouth machine body 100, a mounting ring 102 is slidably connected to the outer wall of the flat-mouth machine body 100, two groups of brackets 103 are fixedly connected to the outer wall of the mounting ring 102, a fixing ring 104 is rotatably connected to the outer wall of the two groups of brackets 103 on one side close to each other, two groups of clamping plates 106 are arranged inside the fixing ring 104, and a bevel rotation mechanism 200 is arranged on the outer walls of the two groups of brackets 103;

[0029] The oblique rotation mechanism 200 includes a rotating shaft 201, and the outer walls of the two groups of brackets 103 on the side close to each other are rotatably connected with the rotating shaft 201, and one end of the two groups of rotating shafts 201 are fixedly connected to the outer wall of the fixing ring 104, the outer wall of one group of brackets 103 is fixedly connected with a control box 202, and one end of one group of rotating shafts 201 extends to the inside of the control box 202, and one end of one group of rotating shafts 201 extending to the inside of the control box 202 is provided with a rectangular groove, and the inner wall of the rectangular groove is slidably connected with a rectangular rod 203, and the end of the rectangular rod 203 is fixedly connected with a gear 204, the inner wall of the control box 202 is fixedly connected with two groups of tooth blocks 205, and the two groups of tooth blocks 205 are meshed with the gear 204, the outer wall of the gear 204 is fixedly connected with a pull handle 206, and one end of the pull handle 206 extends to the outside of the control box 202, the outer wall of the gear 204 is fixedly connected with a return spring, and one end of the return spring is fixedly connected to the inner wall of the control box 202.

[0030] When it is necessary to cut the pipe into a bevel at a certain angle, it is only necessary to pull the handle 206 to drive the gear 204 to separate from the tooth block 205. At this time, the handle 206 can be rotated to drive the gear 204 to rotate. The gear 204 can drive the rotating shaft 201 to rotate through the rectangular rod 203 and the rectangular groove. The rotating shaft 201 can drive the fixing ring 104 to rotate, and the fixing ring 104 can drive the two sets of clamps 106 to rotate. When the clamps 106 are rotated to a suitable angle, the handle 206 can be released to fix the rotation angle of the fixing ring 104 and the clamps 106. At this time, the pipe can be clamped between the two sets of clamps 106 for bevel cutting.

[0031] Please refer to Figure 1-2 The inner wall of the fixing ring 104 is fixedly connected with two sets of sliding rods 105, and the inner walls of the two sets of clamping plates 106 are slidably connected with the outer walls of the two sets of sliding rods 105, the outer walls of the two sets of clamping plates 106 on the side away from each other are rotatably connected with bolts 107, and one end of the two sets of bolts 107 are threadedly connected to the inner wall of the fixing ring 104, and the ends of the two sets of bolts 107 away from each other are fixedly connected with a turning handle 108.

At this time, the pipe fitting is placed between the two sets of clamping plates 106, and then the two sets of handles 108 are rotated clockwise to drive the two sets of bolts 107 to rotate, so as to drive the two sets of clamping plates 106 closer to each other to clamp the pipe fitting.

[0033] Please refer to Figure 2-4 The outer wall of the flat-mouth machine body 100 is provided with a quick disassembly and assembly mechanism 300, which includes a mounting seat 301. The outer wall of the flat-mouth machine body 100 is fixedly sleeved with a mounting shaft, and the inner wall of the mounting shaft is provided with multiple groups of slide grooves, and the inner walls of the multiple groups of slide grooves are all slidably connected with a clamping block 302, and the outer walls of the multiple groups of clamping blocks 302 are all fixedly connected with a limit spring, and one end of the multiple groups of limit springs is respectively fixedly connected to the inner walls of the multiple groups of slide grooves, and the outer wall of the mounting ring 102 is provided with multiple groups of clamping grooves 303. And the multiple groups of blocks 302 are respectively matched with the multiple groups of slots 303, the outer walls of the multiple groups of blocks 302 are fixedly connected with connecting rods 304, and one ends of the multiple groups of connecting rods 304 extend to the outside of the mounting seat 301, the outer wall of the mounting seat 301 is rotatably sleeved with a swivel 305, and the outer wall of the swivel 305 is provided with multiple groups of arc grooves 306, the outer walls of the multiple groups of connecting rods 304 are fixedly connected with movable shafts 307, and the outer walls of the multiple groups of movable shafts 307 are respectively slidably connected to the inner walls of the multiple groups of arc grooves 306.

[0034] When the clamping plate 106 needs to be replaced, it is only necessary to rotate the rotating ring 305 to drive the multiple groups of arc grooves 306 to rotate at the same time. When the multiple groups of arc grooves 306 rotate, the multiple groups of connecting rods 304 can be driven to move toward the outside of the rotating ring 305 through the multiple groups of movable shafts 307 at the same time. The multiple groups of connecting rods 304 can drive the multiple groups of card blocks 302 to move into the multiple groups of sliding grooves at the same time. At this time, the multiple groups of card blocks 302 are separated from the multiple groups of card grooves 303 at the same time, and the mounting ring 102 can be pulled out of the mounting seat 301. When installing the splint 106, it is only necessary to insert the mounting ring 102 into the mounting seat 301. The outer wall of the mounting ring 102 can squeeze the multiple groups of blocks 302 into the multiple groups of slide grooves at the same time through the inclined surfaces of the multiple groups of blocks 302. When the multiple groups of grooves 303 move to the positions of the multiple groups of blocks 302, the multiple groups of limit springs can respectively push the multiple groups of blocks 302 into the multiple groups of grooves 303. At this time, the mounting ring 102 is fixed inside the mounting seat 301, which is very fast.

[0035] Please refer to Figure 1 The outer wall of the rotating ring 305 is provided with a plurality of anti-skid grooves.

[0036] The provision of multiple sets of anti-slip grooves makes it easier to rotate the rotating ring 305.

[0037] During use, when it is necessary to cut the bevel of the pipe fitting into a bevel, it is only necessary to pull the handle 206, and then the fixing ring 104 can be rotated to drive the two sets of clamps 106 to rotate a certain angle. At this time, the clamps 106 can drive the cut of the pipe fitting to rotate to a certain angle, and it is only necessary to loosen the handle 206 to fix the angle of the fixing ring 104. At this time, the cutter 101 can cut the cut of the pipe fitting into a bevel, so that the cut of the pipe fitting can be cut into bevels of different angles. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
