However, existing flange machining fixtures suffer from the following problems: difficulty in simultaneously and stably clamping multiple flanges, and the flanges are prone to sliding and shifting during clamping, affecting machining accuracy; the assembly and transmission stability of the fixture components is poor, and the synchronous drive effect is inadequate, leading to inconsistent clamping adjustments for multiple flanges. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a clamp for flange processing, which includes a frame assembly and a clamping adjustment assembly. The frame assembly provides a stable assembly base, and the clamping adjustment assembly enables synchronous and stable clamping and anti-slip treatment of multiple flanges, thus solving the problems of difficult multi-station stable clamping, easy flange slippage, and poor synchronous driving effect mentioned in the background technology.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamp for flange processing, comprising a frame assembly and a clamping and adjusting assembly disposed on the frame assembly, wherein the frame assembly provides an overall mounting support structure and the clamping and adjusting assembly performs the functions of clamping and adjusting the flange.
[0007] The frame assembly includes a rectangular frame, which serves as the main support frame. The rectangular frame has waist-shaped holes on the front and rear sides of its bottom end, which facilitates the installation and fixation of the clamp and external equipment. An assembly plate is fixedly connected to the upper center of one end of the rectangular frame. The assembly plate is used to install related components of the clamping and adjusting assembly. Three U-shaped frames are fixedly connected in an array at the top of the assembly plate. The U-shaped frames are used to assemble the connecting shaft.
[0008] The clamping and adjusting assembly includes a connecting shaft rotatably mounted in the middle of three U-shaped frames. The connecting shaft provides support for the rotation of the clamping component. The bottom of the three connecting shafts is rotatably mounted on an assembly plate, and the three connecting shafts are equipped with a synchronous drive rotation mechanism to ensure that the multiple connecting shafts rotate and adjust synchronously.
[0009] A clamping base is fixedly connected to the top of the connecting shaft. The clamping base is used to place the flange. A screw is fixedly connected to the center of the top of the screw. A clamping pressure seat is threaded to the outside of the screw. By rotating the clamping pressure seat, the flange can be clamped and released using the screw thread transmission. A clamping anti-slip component is provided between the clamping pressure seat and the clamping base to prevent the flange from sliding during processing.
[0010] As a further improvement of this utility model: a second bearing assembly hole is provided between the upper and lower side walls of the middle part of the U-shaped frame, and a first bearing assembly hole is provided between the upper and lower side walls of the assembly plate corresponding to the three second bearing assembly holes. The bearing assembly holes are used to install double ball bearings to ensure the smooth rotation of the connecting shaft.
[0011] As a further improvement of this utility model: double ball bearings are installed in both the first bearing assembly hole and the second bearing assembly hole. Each pair of double ball bearings arranged symmetrically on top of each other are assembled on the outside of the connecting shaft on the corresponding side. The double ball bearings can reduce the friction when the connecting shaft rotates and improve rotational stability and accuracy.
[0012] As a further embodiment of this utility model: the synchronous drive rotation mechanism includes a reduction drive fixedly installed on the bottom wall of the rectangular frame. The reduction drive provides power for the rotation of the connecting shaft. A pulley is fixedly connected to its top drive end. The synchronous drive rotation mechanism also includes pulleys fixedly connected to the bottom ends of the three connecting shafts. Power transmission is achieved through the mutual cooperation of the pulleys.
[0013] As a further improvement of this utility model, each pair of adjacent pulleys is connected by a set of synchronous belts. By using synchronous belt drive, the three connecting shafts are ensured to rotate synchronously, thereby realizing the synchronous clamping and adjustment of multiple flanges.
[0014] As a further embodiment of this utility model: the clamping anti-slip assembly includes multiple anti-slip grooves formed at equal angles on the outer periphery of the top of the clamping base, and the clamping anti-slip assembly also includes multiple anti-slip protrusions fixedly connected at equal angles on the outer periphery of the bottom of the clamping pressure seat. When clamping the flange, the anti-slip protrusions are embedded in the flange portion near the anti-slip grooves to increase friction and prevent slippage.
[0015] As a further improvement of this utility model: a lever is fixedly connected to each side of the top of the clamping pressure seat, and the lever facilitates the operator to rotate the clamping pressure seat to perform clamping and tightening operations.
[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0027] Please see Figures 1-4 In this embodiment of the present invention, a clamp for processing a flange includes a frame assembly 1 and a clamping and adjusting assembly 2 disposed on the frame assembly 1. The frame assembly 1 is used to provide an overall installation support structure, and the clamping and adjusting assembly 2 is used to realize the clamping and adjusting functions of the flange.
[0028] The frame assembly 1 includes a rectangular frame 15, which serves as the main support frame. The rectangular frame 15 has waist-shaped holes 16 on both the front and rear sides of its bottom end. The waist-shaped holes 16 facilitate the installation and fixation of the clamp and external equipment. An assembly plate 11 is fixedly connected to the upper middle part of one end of the rectangular frame 15. The assembly plate 11 is used to install related parts of the clamping and adjusting assembly 2. Three U-shaped frames 12 are fixedly connected in an array at the top of the assembly plate 11. The U-shaped frames 12 are used to assemble the connecting shaft 23.
[0029] The clamping adjustment assembly 2 includes a connecting shaft 23 rotatably mounted in the middle of three U-shaped frames 12. The connecting shaft 23 provides support for the rotation of the clamping component. The bottom of the three connecting shafts 23 is rotatably mounted on the mounting plate 11, and the three connecting shafts 23 are equipped with a synchronous drive rotation mechanism to ensure that the multiple connecting shafts 23 rotate and adjust synchronously.
[0030] A clamping base 27 is fixedly connected to the top of the connecting shaft 23. The clamping base 27 is used to place the flange. A screw 28 is fixedly connected to the center of its top. A clamping pressure seat 210 is threadedly connected to the outside of the screw 28. By rotating the clamping pressure seat 210, the flange can be clamped and released by the thread drive of the screw 28. A clamping anti-slip component is provided between the clamping pressure seat 210 and the clamping base 27 to prevent the flange from sliding during processing.
[0031] A second bearing assembly hole 14 is provided between the upper and lower side walls of the U-shaped frame 12. A first bearing assembly hole 13 is provided between the upper and lower side walls of the assembly plate 11 corresponding to the three second bearing assembly holes 14. The bearing assembly holes are used to install double ball bearings 22 to ensure the smooth rotation of the connecting shaft 23.
[0032] Double ball bearings 22 are installed in both the first bearing mounting hole 13 and the second bearing mounting hole 14. Each pair of double ball bearings 22 arranged symmetrically are mounted on the outside of the connecting shaft 23 on the corresponding side. The double ball bearings 22 can reduce the friction when the connecting shaft 23 rotates, and improve the rotational stability and accuracy.
[0033] The synchronous drive rotation mechanism includes a reduction drive 21 fixedly installed on the bottom wall of the rectangular frame 15. The reduction drive 21 provides power for the rotation of the connecting shaft 23. A pulley 24 is fixedly connected to its top drive end. The synchronous drive rotation mechanism also includes pulleys 24 fixedly connected to the bottom ends of the three connecting shafts 23. Power transmission is achieved through the mutual cooperation of the pulleys 24.
[0034] Each pair of adjacent pulleys 24 is connected by a set of synchronous belts 26. The synchronous belts 26 are used to drive the three connecting shafts 23 to rotate synchronously, thereby realizing the synchronous clamping and adjustment of multiple flanges.
[0035] The clamping anti-slip assembly includes multiple anti-slip grooves 29 formed at equal angles on the outer periphery of the top of the clamping base 27, and multiple anti-slip protrusions 211 fixedly connected at equal angles on the outer periphery of the bottom of the clamping pressure seat 210. When clamping the flange, the anti-slip protrusions 211 are embedded in the flange part near the anti-slip grooves 29 to increase friction and prevent slippage.
[0036] A lever 25 is fixedly connected to each side of the top of the clamping pressure seat 210. The lever 25 facilitates the operator to rotate the clamping pressure seat 210 to perform clamping and loosening operations.
[0037] The working principle of this utility model is as follows: In use, the clamp is installed onto the flange processing equipment through the waist-shaped hole 16 at the bottom of the rectangular frame 15. When it is necessary to clamp the flange, the clamping pressure seat 210 is first rotated by the lever 25 to disengage it from the screw 28. The center hole of the flange is then passed through the screw 28 and placed on the clamping base 27. The operator rotates the clamping pressure seat 210 by the lever 25, and the screw 28 is used for thread transmission to move the clamping pressure seat 210 downward, pressing the flange tightly onto the clamping base 27. The reduction drive 21 is then activated, and the reduction drive 21 drives the belt connected to its drive end. When pulley 24 rotates, it drives three other pulleys 24 to rotate synchronously via synchronous belt 26, which in turn causes connecting shaft 23 to rotate. The clamping base 27 at the top of connecting shaft 23 rotates accordingly. This rotation can be used to adjust the flange processing angle to cooperate with subsequent flange processing operations. In addition, the anti-slip protrusion 211 at the bottom of clamping pressure seat 210 cooperates with the anti-slip groove 29 at the top of clamping base 27 to increase the friction on the flange and prevent the flange from sliding during processing. After processing is completed, the clamping pressure seat 210 is rotated in the opposite direction to disengage it from screw 28. At this time, the flange is released and can be removed.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
