Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically a clamping device for processing bent pipe joints. Background Technology

[0002] A pipe bend is a pipe fitting used for connecting pipes at bends. The clamping device used in processing pipe bends is mainly used to fix and clamp the pipe bend body to prevent displacement during further processing and thus avoid processing errors.

[0003] Utility model patent CN211219471U discloses a pipe bend clamping device for hydraulic construction, including a base and a fourth electric push rod. The fourth electric push rod and a movable block are respectively installed on both sides of the top of the base. A bearing is fixedly installed on the top of the movable block, and a support column is inserted into the inner cavity of the bearing. A top plate is fixedly installed on the top of both the support column and the fourth electric push rod. A clamping mechanism is connected to the outer end of the top plate. The clamping mechanism includes a clamping plate and a first electric push rod. Clamping plates are hinged to both sides of the free end of the top plate. This utility model uses two sets of clamping plates to firmly clamp two sets of joined pipe bends. The angle can be adjusted by a motor, and the horizontal and vertical positions can be adjusted by a second and third electric push rod, resulting in high alignment accuracy during welding, thus improving welding precision and extending service life. However, the clamping device still has shortcomings: it uses a symmetrical clamping plate structure to clamp the joint or pipe, but the body of the bent pipe joint has a certain degree of curvature. This ordinary clamping structure cannot fully adapt to the curvature of the bent pipe joint, resulting in unstable clamping and easy to cause processing errors due to deflection and displacement. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the above-mentioned pipe joint clamping device uses a symmetrical clamping plate structure to clamp the joint or pipe, but the pipe joint body has a certain degree of curvature. This ordinary clamping structure cannot fully adapt to the curvature of the pipe joint, resulting in unstable clamping and easy processing errors due to deflection and displacement. The present invention provides a clamping device for processing pipe joints.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for processing pipe bends, comprising: a fixed base plate, wherein a rotating plate one and a rotating plate two are symmetrically hinged to the top surface of the fixed base plate; an arc-shaped semi-ring is fixed to the top of the rotating plate one; a clamping square column is connected through one side of the arc-shaped semi-ring; a clamping arc plate is fixed to one end of the clamping square column; a connecting side column is fixed to the other end of the clamping square column; a connecting stud is fixed to the bottom inner side of the connecting side column; a connecting screw is screwed to the connecting stud and a connecting screw cylinder; a rotating block one is hinged to one end of the top surface of the fixed base plate; an adjusting stud is fixed to one end of the rotating block one; a rotating block two is hinged to one end of the rotating plate one; and an adjusting screw cylinder is rotatably connected to one end of the rotating block two.

[0006] As a further embodiment of this utility model: the arc-shaped semi-ring is configured as an arc panel with a semi-circular cross-section, the clamping square column is configured as a column with a square cross-section, and the clamping arc panel is fixed to one end of the clamping square column and located inside the arc-shaped semi-ring.

[0007] As a further embodiment of this utility model: the clamping square column is fixedly connected to the connecting side column in parallel with the connecting stud, and two sets of the clamping square column, the clamping arc plate, the connecting side column and the connecting stud are provided.

[0008] As a further embodiment of this utility model: the two sets of connecting studs have opposite thread directions and are both screwed into the same set of connecting cylinders, so that the two sets of connecting studs with opposite thread directions can move synchronously relative to each other when rotating the connecting cylinder.

[0009] As a further embodiment of this utility model: the number and specifications of the adjusting stud and the adjusting cylinder are compatible and screwed together; a locking block is fixed to the top of the adjusting cylinder; and a locking groove is opened at the bottom of the rotating block; the number and specifications of the locking groove are compatible with those of the locking block.

[0010] As a further embodiment of this utility model: the first rotating plate and the second rotating plate are symmetrically arranged on the top surface of the fixed base plate. The second rotating plate is provided with the same number and specifications as the first rotating plate, including an arc-shaped semi-ring, a clamping square column, a clamping arc plate, a connecting side column, a connecting stud, a connecting screw, a first rotating block, an adjusting stud, a second rotating block, an adjusting screw, a slot, and a locking block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, two sets of arc-shaped semi-rings for supporting the bent pipe joint are respectively hinged to the top of the fixed base plate through rotating plate one and rotating plate two. The rotation angle of each of them is controlled by adjusting the screw stud and adjusting the screw cylinder to flexibly adapt to the clamping requirements of bent pipe joints of different specifications and curvatures. This support-type clamping method is more stable and reduces the risk of deviation caused by displacement during processing.

[0013] 2. The clamping arc plates at the ends of the two sets of clamping square columns move synchronously inward or outward to clamp or release the fixation of the two sides of the bent pipe joint. The two sets of connecting studs that are fixed to the clamping square columns through the connecting side columns have opposite thread directions and are symmetrical in position when connected to the connecting screw cylinder, so that when the connecting screw cylinder is rotated, it drives the two arc-shaped semi-rings to move synchronously inward or outward, which facilitates synchronous control of the clamping of the two sides of the bent pipe joint and improves the adjustment and clamping efficiency.

The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 6 In this embodiment of the utility model, a clamping device for processing bent pipe joints includes: a fixed base plate 1, a rotating plate 1 2 and a rotating plate 2 15 symmetrically hinged to the top surface of the fixed base plate 1, an arc-shaped semi-ring 3 fixed to the top of the rotating plate 1 2, a clamping square column 4 penetrating one side of the arc-shaped semi-ring 3, a clamping arc plate 5 fixed to one end of the clamping square column 4, a connecting side column 6 fixed to the other end of the clamping square column 4, a connecting stud 7 fixed to the bottom inner side of the connecting side column 6, a connecting screw cylinder 8 screwed to the connecting stud 7, a rotating block 1 9 hinged to one end of the top surface of the fixed base plate 1, an adjusting stud 10 fixed to one end of the rotating block 1 9, a rotating block 2 11 hinged to one end of the rotating plate 1 2, and an adjusting screw cylinder 12 rotatably connected to one end of the rotating block 2 11.

[0024] Reference Figures 2 to 4 The arc-shaped semi-ring 3 is set as an arc panel with a semi-circular cross-section, and the clamping square column 4 is set as a column with a square cross-section. The clamping arc plate 5 is fixed to one end of the clamping square column 4 and located inside the arc-shaped semi-ring 3. The clamping square column 4 is fixed with connecting studs 7 in parallel through connecting side columns 6. There are two sets of clamping square columns 4, clamping arc plates 5, connecting side columns 6 and connecting studs 7. The two sets of connecting studs 7 have opposite thread directions and are both screwed into the same set of connecting screw cylinders 8. The two sets of connecting studs 7 with opposite thread directions can move synchronously relative to each other when rotating the connecting screw cylinder 8.

[0025] The above scheme is adopted: the bent pipe joint is placed between two arc-shaped semi-rings 3. The clamping arc plates 5 at the guide ends of the two sets of clamping square columns 4 move inward or outward synchronously to clamp or loosen the fixation of the two ends of the bent pipe joint. The two sets of connecting studs 7, which are fixed to the clamping square columns 4 through the connecting side columns 6, have opposite thread directions and are symmetrical when connected to the connecting screw cylinder 8, so that when the connecting screw cylinder 8 is rotated, it drives the two arc-shaped semi-rings 3 to move inward or outward synchronously, which facilitates the synchronous control of clamping the two ends of the bent pipe joint and improves the adjustment and clamping efficiency.

[0026] Reference Figures 4 to 6 The adjusting studs 10 and adjusting cylinders 12 are matched in number and specifications and are screwed together. The top of the adjusting cylinder 12 is fixed with a locking block 14. The bottom of the rotating block 11 is provided with a locking groove 13. The locking groove 13 and the locking block 14 are matched in number and specifications. The rotating plate 11 and the rotating plate 215 are symmetrically arranged on the top surface of the fixed base plate 1. The rotating plate 215 is provided with the same number and specifications as the rotating plate 12, including an arc-shaped semi-ring 3, a clamping square column 4, a clamping arc plate 5, a connecting side column 6, a connecting stud 7, a connecting cylinder 8, a rotating block 11, an adjusting stud 10, a rotating block 21, an adjusting cylinder 12, a locking groove 13, and a locking block 14.

[0027] The above scheme is adopted: two sets of arc-shaped semi-rings 3 for supporting the pipe joints are respectively hinged to the fixed base plate 1 through rotating plate 1 2 and rotating plate 2 15. The rotation angle of each of them is controlled by adjusting the screw stud 10 and adjusting screw cylinder 12 to flexibly adapt to the clamping requirements of pipe joints of different specifications and curvatures. This support-type clamping method is more stable and reduces the risk of deviation caused by displacement during processing.

[0028] The working principle of this utility model is as follows: In use, the bent pipe joint is placed between two arc-shaped semi-rings 3. The clamping arc plates 5 at the guide ends of the two sets of clamping square columns 4 move inward or outward synchronously to clamp or loosen the fixation of the two ends of the bent pipe joint. The two sets of connecting studs 7, which are fixed to the clamping square columns 4 through the connecting side columns 6, have opposite thread directions and are symmetrical when connected to the connecting screw cylinder 8, so that when the connecting screw cylinder 8 is rotated, it drives the two arc-shaped semi-rings 3 to move inward or outward synchronously. This facilitates the synchronous control of clamping the two ends of the bent pipe joint at one time and improves the adjustment and clamping efficiency. The two sets of arc-shaped semi-rings 3 used to support the bent pipe joint are respectively hinged to the fixed base plate 1 through rotating plate 1 2 and rotating plate 2 15. The rotation angle of each is controlled by adjusting the screw stud 10 and adjusting screw cylinder 12 to flexibly adapt to the clamping requirements of bent pipe joints of different specifications and curvatures. This support-type clamping method is more stable and reduces the risk of deviation caused by displacement during processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
