Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning and clamping equipment technology, and in particular to a positioning and clamping device for processing engineering machinery housings. Background Technology
[0002] Construction machinery is machinery used in engineering projects. During the processing of construction machinery, the machining of the machine housing is involved, including operations such as grinding, painting, and plastic forming. In order to improve the accuracy of the housing machining, it is usually necessary to position and clamp the housing.
[0003] When positioning and clamping devices clamp the housing, they usually contact and clamp it from the outside. However, the contact area is blocked. Existing positioning and clamping devices are inconvenient to adjust the clamping position during positioning, which makes it impossible to process the blocked area and affects the processing effect. In addition, traditional clamping methods have the problems of cumbersome operation and low clamping and disassembly efficiency.
[0004] Therefore, those skilled in the art urgently need to develop a positioning and clamping device for machining engineering machinery housings. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning and clamping device for machining engineering machinery housings.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning and clamping device for processing engineering machinery housing, comprising a base, a frame on the base, a support seat on the frame, a clamping seat connected to the left end of the support seat, a horizontally placed drive rod on the left side of the clamping seat, a first telescopic hydraulic cylinder for driving the drive rod to move horizontally connected to the support seat, the clamping seat having a disc-shaped structure, the drive rod being located at the center of the clamping seat, a gear seat connected to the clamping seat being provided on the outer side of the drive rod, and a rack connected to the drive rod being provided between the drive rod and the gear seat;
[0007] The rack and gear seat are multiple in number and are evenly distributed in a ring around the drive rod. Multiple horizontally arranged gears are rotatably mounted on the gear seat. The multiple gears mesh with the corresponding racks for transmission. Each gear is equipped with a swing rod. A clamp is provided on the side of the swing rod away from the gear. The clamp is rotatably connected to the swing rod on the adjacent side.
[0008] Preferably, the number of racks is four, the number of gear seats corresponding to each rack is two, the number of gears between two adjacent gear seats is six and evenly divided into three groups, and the gears in each group are rotatably positioned between two adjacent gear seats via a gear shaft.
[0009] Preferably, each gear shaft is connected to a swing arm, and there are four clamps, each clamp being hinged to multiple swing arms on the adjacent side.
[0010] Preferably, the frame and the support base are hinged to each other, the bottom of the support base is provided with a support plate, a second telescopic cylinder is provided between the support plate and the base, the output end of the second telescopic cylinder is hinged to the support plate, and the bottom of the second telescopic cylinder is rotatably connected to a base plate, which is connected to the base.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, the first telescopic hydraulic cylinder drives the rack-driven rod to move to the left, and through gear meshing, the swing rod changes from inclined to vertical, causing the clamping plate to expand outward and clamp the housing. Disassembly is achieved by retracting the hydraulic cylinder, making operation convenient and efficient. The drive rod is supported by a gear seat and equidistantly distributed gear sets, ensuring stable movement. The gear shaft drives the swing rod to hinge the clamping plate, enabling outward movement. Clamping on the inner side facilitates adjustment of the clamping position, with no obstructed areas, making processing convenient. The outer protrusion of the clamping plate and the right-end baffle prevent slippage when the housing is clamped or when the clamping seat is tilted. Simultaneously, the second telescopic hydraulic cylinder can drive the support seat to rotate and adjust the clamping seat's elevation angle, meeting multi-angle clamping requirements.

[0020] Please see Figures 1-3 This utility model provides an embodiment: a positioning and clamping device for processing engineering machinery housing, including a base 1, a frame 2 on the base 1, a support seat 3 on the frame 2, a clamping seat 4 connected to the left end of the support seat 3, a horizontally placed drive rod 6 on the left side of the clamping seat 4, a first telescopic cylinder 5 for driving the drive rod 6 to move horizontally connected to the support seat 3, the clamping seat 4 has a disc-shaped structure, the drive rod 6 is located at the center of the clamping seat 4, a gear seat 9 connected to the clamping seat 4 is provided on the outside of the drive rod 6, and a rack 7 connected to the drive rod 6 is provided between the drive rod 6 and the gear seat 9.
[0021] The number of racks 7 and gear seats 9 are multiple and evenly distributed in a ring around the drive rod 6. Multiple horizontally arranged gears 8 are rotatably mounted on the gear seat 9. The multiple gears 8 mesh with the corresponding racks 7 for transmission. Each gear 8 is equipped with a swing rod 10. A clamping plate 11 is provided on the side of the swing rod 10 away from the gear 8. The clamping plate 11 is rotatably connected to the swing rod 10 on the adjacent side.
[0022] The first telescopic cylinder 5 drives the drive rod 6 to move to the left. The rack 7 on the drive rod 6 meshes with the gear 8, which in turn drives the swing rod 10 on the gear 8 to rotate. The swing rod 10 changes from an inclined direction to a vertical direction, thereby expanding the clamping plate 11 and clamping the shell sleeved on the outside of the clamping plate 11.
[0023] Furthermore, there are four racks 7, two gear seats 9 corresponding to each rack 7, and six gears 8 between two adjacent gear seats 9, which are evenly divided into three groups. Each group of gears 8 is rotatably positioned between two adjacent gear seats 9 via a gear shaft. Each gear shaft is fixedly connected to a swing rod 10. There are four clamps 11, and each clamp 11 is hinged to multiple swing rods 10 on the adjacent side.
[0024] The drive rod 6 is supported by gear seats 9 and gear sets around its perimeter, which improves the stability of the drive rod 6 movement; the three sets of gears between two adjacent gear seats 9 are equidistantly distributed, and drive the rotation of gear 8 and gear shaft through rack 7. The gear shaft drives the connected swing rod 10 to rotate. The swing rod 10 is hinged to the clamping plate 11, which moves the clamping plate 11 outward.
[0025] Furthermore, the outer surface of the clamping plate 11 is provided with protrusions (not shown in the figure) to prevent the shell from sliding during the clamping process.
[0026] Furthermore, the frame 2 and the support base 3 are hinged together. The bottom of the support base 3 is provided with a support plate 12. A second telescopic cylinder 13 is provided between the support plate 12 and the base 1. The output end of the second telescopic cylinder 13 is hinged to the support plate 12. The bottom of the second telescopic cylinder 13 is rotatably connected to a base plate 14, which is connected to the base 1. The second telescopic cylinder 13 drives the support base 3 to rotate, thereby controlling the elevation angle of the clamping seat 4, thus realizing multi-angle clamping operations.
[0027] Furthermore, a baffle (not shown in the figure) is provided at the right end of the clamping plate 11 to prevent the housing from sliding when the clamping seat 4 tilts during the clamping process.
[0028] Furthermore, the clamping plate 11 can adopt an arc-shaped structure to avoid damage to the shell caused by the right-angled edges.
[0029] The working principle of this utility model is as follows: When in use, the housing is fitted onto the outside of the clamping plate 11. The first telescopic cylinder 5 drives the drive rod 6 to move to the left. The rack 7 on the drive rod 6 meshes with the gear 8, which in turn drives the swing rod 10 on the gear 8 to rotate. The swing rod 10 changes from an inclined direction to a vertical direction, thereby expanding the clamping plate 11 and clamping the housing fitted onto the outside of the clamping plate 11. When angle adjustment is required, the second telescopic cylinder 13 drives the support base 3 to rotate, thereby controlling the elevation angle of the clamping base 4, thus realizing multi-angle clamping operations. Disassembly only requires controlling the retraction of the first telescopic cylinder 5, making the operation convenient and efficient.
