Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder boring technology, specifically to a hydraulic cylinder bracket boring fixture. Background Technology

[0002] Boring refers to the further processing of forged, cast, or drilled holes. Boring can enlarge the hole diameter, improve accuracy, reduce surface roughness, and can also effectively correct the misalignment of the original hole axis.

[0003] When machining the cylinder body of an existing hydraulic cylinder, a boring bar is required to precision bore the inner wall of the cylinder body. Currently, hydraulic cylinders come in various specifications and models, with different cylinder body diameters and shapes, commonly cylindrical and square. Existing boring devices generally only support cylinder bodies of different diameters, and when fixing cylinder bodies of different shapes, instability can easily occur. Therefore, existing boring devices require different fixtures when boring different shaped hydraulic cylinders, resulting in poor fixture versatility and inconvenience. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a hydraulic cylinder bracket boring fixture that can clamp and fix hydraulic cylinder bodies of different diameters and shapes, offering better versatility and greater ease of use.

[0005] This utility model is achieved through the following technical solution: a hydraulic cylinder bracket boring fixture, comprising a frame, on which two clamping members are provided, each clamping member comprising two arc-shaped plates, the two ends of which are connected by bolts, a connecting rod fixed between the two arc-shaped plates, a support rod hinged to the outer wall of the connecting rod, the end of the support rod away from the connecting rod being hinged to the frame; multiple threaded rods are threadedly connected to both arc-shaped plates of the clamping member, the multiple threaded rods are distributed along the arc direction of the arc-shaped plates and penetrate the arc-shaped plates from the outside to the inside, the axes of the threaded rods on the two arc-shaped plates intersect at a point, and a clamping block is rotatably connected to the end of the threaded rod located on the inner side of the arc-shaped plate.

[0006] This design employs a clamping mechanism consisting of two arc-shaped plates forming a ring-like enclosure. Rotating the threaded rod causes multiple threaded rods to converge towards the center, thus clamping the hydraulic cylinder body and securing the tree. Adjusting the threaded rods allows for clamping hydraulic cylinders of different diameters and shapes, enhancing applicability and ease of use. The upper and lower clamping components clamp the hydraulic cylinder body vertically, providing greater stability. A connecting rod supports the two clamping components on the frame, forming a clamping bracket that supports the hydraulic cylinder body, keeping it vertical and facilitating boring.

[0007] As an optimization, three threaded rods are evenly distributed on each curved plate, with the included angle between the extensions of adjacent threaded rods being 60°. This optimized scheme results in greater stability when the three threaded rods are clamped together at a 60-degree angle.

[0008] As an optimization, a rubber pad is fixed to the end of the clamping block away from the threaded rod. This optimization prevents the clamping block from damaging the cylinder surface during clamping.

[0009] As an optimization, the support rod includes a threaded long rod hinged to the connecting rod, and a sleeve sleeved on the threaded long rod. An adjusting sleeve is screwed onto the threaded long rod, and the adjusting sleeve is rotatably mounted on the upper end of the sleeve. The lower end of the sleeve is hinged to the frame. This optimized solution drives the threaded long rod to extend or retract along the sleeve by rotating the adjusting sleeve, thereby achieving the extension or retraction of the support rod. This facilitates adjustment of the clamping position in the height direction of the clamping component, making it easier to clamp hydraulic cylinders of different lengths and further improving usability.

[0010] As an optimization, a telescopic cylinder is fixedly installed at the bottom of the frame. The telescopic end of the cylinder faces upward and is fixedly connected to a support base plate, which is located directly below the two clamping components. This optimized solution allows the height of the support base plate to be adjusted by extending and retracting the telescopic cylinder, thereby facilitating support for the bottom of hydraulic cylinders at different heights, improving stability, and making it more convenient to use.

[0011] The beneficial effects of this utility model are as follows: The clamping component adopts a ring-shaped surrounding structure formed by two arc-shaped plates. By rotating the threaded rod, multiple threaded rods converge towards the center, thereby clamping the hydraulic cylinder body and achieving a tight grip on the tree. By adjusting the threaded rod, hydraulic cylinders of different diameters and shapes can be clamped, making it more applicable and convenient to use. The upper and lower clamping components clamp the hydraulic cylinder body from top to bottom, resulting in higher stability. Furthermore, the two clamping components are supported on the frame by two support rods, forming a bracket-type boring structure, thereby supporting the hydraulic cylinder body and keeping it in a vertical position, facilitating downward boring by the boring tool on the frame.

[0012] By rotating the adjusting sleeve, the threaded rod connected by the screw is driven to extend or retract along the sleeve, thereby extending or shortening the support rod. This facilitates adjustment of the clamping position in the height direction of the clamping component, making it convenient to clamp hydraulic cylinders of different lengths, further improving ease of use and enhancing versatility.

[0013] The height of the support base plate can be adjusted by extending and retracting the telescopic cylinder, which facilitates support for the bottom of the hydraulic cylinder body at different heights, further improving the stability of the hydraulic cylinder body and making it more convenient to use.

[0024] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0025] like Figures 1-8 As shown, a hydraulic cylinder bracket boring fixture includes a frame 36. Two clamping members 1 are provided on the frame 36, each clamping member 1 comprising two arc-shaped plates 11 facing each other. Both ends of the two arc-shaped plates 11 are connected by bolts 14. In this embodiment, the arc-shaped plates 11 have a semi-circular structure, and the two arc-shaped plates 11 together form a circular enclosure.

[0026] The top of the frame 36 described in this embodiment is also provided with a boring tool 37 that can move up, down, left, and right. The boring tool 37 is located above the two clamping members 1. After the clamping members 1 clamp and fix the hydraulic cylinder body 38, the boring tool 37 is used to bore the hydraulic cylinder body 38. The boring tool 37 is a conventional technology and will not be described in detail here.

[0027] A connecting rod 2 is fixedly connected between the two upper and lower arc-shaped plates 11 of the two clamping members 1. In this embodiment, a connecting rod 2 is provided between the upper and lower arc-shaped plates 11. The upper and lower ends of the connecting rod 2 are welded and fixed to the middle of the upper and lower arc-shaped plates 11, respectively, and the two connecting rods 2 are arranged opposite each other from left to right.

[0028] The clamping member 1 has multiple threaded rods 12 threadedly connected to both arc-shaped plates 11. These threaded rods 12 are distributed along the arc of the arc-shaped plates 11 and penetrate from the outside in. The axes of the threaded rods 12 on the two arc-shaped plates intersect at a single point. In this embodiment, three threaded rods 12 are evenly distributed on the arc-shaped plates 11, with the included angle between the extensions of adjacent threaded rods 12 being 60°. The axes of the six threaded rods 12 of each clamping member 1 intersect at the center of the annular surrounding ring.

[0029] The threaded rod 12 is rotatably connected to a clamping block 13 at one end located inside the arc-shaped plate 11, and a handle is fixedly connected to the other end of the threaded rod located outside the arc-shaped plate. Specifically, an annular groove 132 is provided circumferentially on the outer circular surface of the end of the threaded rod 12. The clamping block 13 includes an annular mounting base 131 and a top plate 134. A retaining ring 133 adapted to the annular groove 132 is fixedly connected to the inner wall of the mounting base 131. The mounting base 131 is engaged in the annular groove 132 of the threaded rod by the retaining ring 133 and rotates circumferentially, thereby realizing the rotatable connection between the clamping block 13 and the threaded rod 12. The top plate 134 is fixedly connected to the end of the mounting base 131 away from the threaded rod 12.

[0030] A rubber pad 15 is fixedly connected to one end of the clamping block 13 away from the threaded rod 12. In this embodiment, the rubber pad 15 is fixedly connected to the top plate 134.

[0031] A support rod 3 is hinged to the outer wall of the connecting rod 2, and the end of the support rod 3 away from the connecting rod 2 is hinged to the frame 36. This embodiment has two connecting rods 2, therefore two support rods 3 are provided. The two support rods support the two clamping components on the frame, forming a bracket structure, which provides vertical support for the hydraulic cylinder body, facilitating downward boring by the boring tool on the frame.

[0032] Specifically, the support rod 3 includes a threaded long rod 31 hinged to the connecting rod 2, and a sleeve 32 sleeved on the threaded long rod 31. An adjusting screw sleeve 33 is screwed onto the threaded long rod 31. The adjusting screw sleeve 33 is rotatably mounted on the upper end of the sleeve 32, and the lower end of the sleeve 32 is hinged to the frame 36.

[0033] Specifically, an annular groove 333 is formed circumferentially on the outer wall of the upper end of the sleeve 32. The adjusting screw sleeve 33 includes an adjusting nut 331 that is screwed and adapted to the threaded rod 31, and a convex ring 332 fixed to the side wall of the adjusting nut 331. The convex ring 332 is adapted to the annular groove 333. The adjusting nut 331 is engaged in the annular groove 333 of the sleeve through the convex ring 332, thereby realizing the rotational connection between the adjusting screw sleeve 33 and the upper end of the sleeve 32, thereby driving the extension and retraction of the threaded rod 31.

[0034] Preferably, a telescopic cylinder 34 is fixedly installed at the bottom of the frame 36. The telescopic end of the telescopic cylinder 34 faces upward and is fixedly connected to a support base plate 35, which is located directly below the two clamping members 1. The height of the support base plate 35 can be adjusted by extending and retracting the telescopic cylinder 34, thereby facilitating the support of the bottom of the hydraulic cylinder body 38 of different heights, further improving stability and making it more convenient to use.

[0035] Working principle: In use, the arc-shaped plates 11 of the two clamping parts 1 are connected and fixed one-to-one with bolts 14. The threaded rods 12 on the arc-shaped plates 11 are rotated to adjust the clamping distance, so that a total of six threaded rods 12 on each clamping part 1 sequentially press against the hydraulic cylinder body 38, thereby clamping the hydraulic cylinder body 38. By clamping the hydraulic cylinder body 38 at both the top and bottom points through the two clamping parts 1, the clamping effect is improved and the stability is higher. Adjusting the height of the support base plate by extending the telescopic cylinder so that the bottom of the hydraulic cylinder body 38 is placed on the support base plate, improving stability and completing the clamping and support of the hydraulic cylinder body 38. Then, the boring tool 37 can be driven to perform boring machining on the hydraulic cylinder body 38.
