Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a one-piece hydraulic clamp. Background Technology

[0002] Planetary gear housings are an important component in axle assemblies, playing a crucial role, especially in reduction gear mechanisms. They are commonly used in planetary gear reducers, and their main function is to support and protect the planetary gears, ensuring their proper operation.

[0003] During the production and processing of planetary gear housings, it is often necessary to process the front and back sides separately. However, because the casting blanks of planetary gear housings have poor consistency in holes during the production and processing stage, they are not easy to position and can easily lead to product scrap. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a one-piece hydraulic clamp that can more easily position the machined planetary gear housing and reduce the scrap rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A hydraulic clamp suitable for integrated applications includes a support plate. A first platform, a second platform, and a support column are fixedly connected to the upper surface of the support plate in sequence. Several chucks are fixedly connected to the upper surface of the second platform. A positioning disc is fixedly connected to the outer wall of the upper end of the second platform. A guide component and a positioning component are connected to the upper end of the support column. The guide component and the positioning component are matched, and the end of the guide component away from the positioning component is matched and aligned with the second platform. Three supports are fixedly connected to the upper surface of the support plate. A first limiting component is connected to the upper surface of each of the three supports. The three supports and the three first limiting components are circumferentially distributed around the second platform. Three second limiting components are connected to the upper surface of the support plate, and the three second limiting components are circumferentially distributed around the first platform.

[0006] Furthermore, the guide assembly includes a rotating rod, a cross-shaped rotating positioning handle, and a positioning rod. The lower end of the rotating rod is fixedly connected to the upper end of the support column. The upper end of the rotating rod passes through the middle of the cross-shaped rotating positioning handle and is rotatably connected to the through-hole of the cross-shaped rotating positioning handle. Mounting holes are provided at two adjacent ends of the cross-shaped rotating positioning handle. The outer wall of the positioning rod is threaded to the inner wall of the mounting hole. The other two ends of the cross-shaped rotating positioning handle are connected to the positioning assembly. The positioning rod is located above the positioning plate.

[0007] Furthermore, the positioning component includes a support block, a threaded rod, and a limiting head. The lower end of the support block is fixedly connected to the upper end of the support column. The other end of the support block is sleeved and threadedly connected to the outer wall of the threaded rod. The end of the threaded rod near the support column is fixedly connected to the limiting head. The two ends of the cross-shaped rotary positioning handle away from the two mounting holes are provided with positioning ports. The outer wall of the limiting head is slidably connected to the inner wall of the positioning port.

[0008] Furthermore, the No. 1 limit component and the No. 2 limit component have the same structure.

[0009] Furthermore, both the first and second limit components include corner cylinders and hydraulic lifting rods.

[0010] Furthermore, the upper ends of the three supports are all fixedly connected to protective shells, and the upper surface of the support plate is fixedly connected to three other protective shells. The inner walls of the six protective shells are all provided with storage cavities, and the six hydraulic lifting rods are located in the six storage cavities respectively.

[0011] Furthermore, the lower side wall of the positioning disk is provided with several chip removal ports, which are staggered with several chucks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This type is suitable for integrated hydraulic fixtures. By setting a No. 1 table and a No. 2 table on the support plate, two workpieces can be processed at the same time, resulting in higher production efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-5 A hydraulic clamp suitable for use in a single unit includes a support plate 1. A first platform 2, a second platform 3, and a support column 9 are fixedly connected to the upper surface of the support plate 1 in sequence. Several chucks 4 are fixedly connected to the upper surface of the second platform 3. A positioning disc 5 is fixedly connected to the outer wall of the upper end of the second platform 3. A guide assembly and a positioning assembly are connected to the upper end of the support column 9. The guide assembly and the positioning assembly are matched, and the end of the guide assembly away from the positioning assembly is matched and aligned with the second platform 3. Three supports 6 are fixedly connected to the upper surface of the support plate 1. A first limit assembly is connected to the upper surface of each of the three supports 6. The three supports 6 and the three first limit assemblies are circumferentially distributed around the second platform 3. Three second limit assemblies are connected to the upper surface of the support plate 1. The three second limit assemblies are circumferentially distributed around the first platform 2.

[0024] like Figures 1 to 5 As shown, when using the integrated hydraulic fixture of this utility model, the two planetary gear housings to be processed are first placed on stage 2 and stage 3 respectively. Then, the planetary gear housings on stage 2 and stage 3 are clamped by three limit components and three limit components, respectively. Then, the two workpieces can be processed normally.

[0025] During processing, the guide and positioning components on the support column 9 can be aligned with the blank holes on the planetary gear housing to increase the yield of finished products.

[0026] like Figures 1-3 As shown, the guide assembly includes a rotating rod 11, a cross-shaped rotating positioning handle 12, and a positioning rod 13. The lower end of the rotating rod 11 is fixedly connected to the upper end of the support column 9. The upper end of the rotating rod 11 passes through the middle of the cross-shaped rotating positioning handle 12 and is rotatably connected to the through-hole of the cross-shaped rotating positioning handle 12. Two adjacent ends of the cross-shaped rotating positioning handle 12 are provided with mounting holes 1202. The outer wall of the positioning rod 13 is threadedly connected to the inner wall of the mounting hole 1202. The other two ends of the cross-shaped rotating positioning handle 12 are connected to the positioning assembly. The positioning rod 13 is located above the positioning disk 5.

[0027] More specifically, when it is necessary to fit and position the blank hole of the planetary gear housing, simply loosen the positioning component to limit the cross-shaped rotary positioning handle 12, and then manually rotate the cross-shaped rotary positioning handle 12. When the positioning rod 13 located in one of the mounting holes 1202 rotates to a certain angle, it is limited again by the positioning component. At this time, it is only necessary to finely adjust the planetary gear housing so that the blank hole on the planetary gear housing is aligned with the positioning rod 13. It is convenient, easy to operate, and accurate in positioning.

[0028] In addition, the positioning rod 13 can be finely adjusted up and down through the thread between the positioning rod 13 and the mounting hole 1202, thereby reducing the friction between the positioning rod 13 and the planetary gear housing.

[0029] like Figure 3 As shown, the positioning assembly includes a support block 10, a threaded rod 14, and a limiting head 15. The lower end of the support block 10 is fixedly connected to the upper end of the support column 9. The other end of the support block 10 is sleeved and threadedly connected to the outer wall of the threaded rod 14. The end of the threaded rod 14 near the support column 9 is fixedly connected to the limiting head 15. The cross-shaped rotary positioning handle 12 has positioning ports 1201 at both ends away from the two mounting holes 1202. The outer wall of the limiting head 15 is slidably connected to the inner wall of the positioning port 1201.

[0030] More specifically, when it is necessary to release the cross-shaped rotary positioning handle 12, simply turn the knob at one end of the threaded rod 14, and then control the threaded rod 14 and the limiting head 15 to move along the support block 10. While the limiting head 15 is moving, it will disengage from the positioning port 1201 of the cross-shaped rotary positioning handle 12. After that, the cross-shaped rotary positioning handle 12 can be rotated normally to make it start to rotate around the rotating rod 11.

[0031] like Figures 1-5As shown, the No. 1 and No. 2 limit components have the same structure. Both the No. 1 and No. 2 limit components include a corner cylinder 8 and a hydraulic lifting rod 16. The outer wall of the hydraulic lifting rod 16 located around the No. 2 platform 3 is fixedly connected to the upper end of the support 6, and the outer wall of the hydraulic lifting rod 16 located around the No. 1 platform 2 is fixedly connected to the upper surface of the support plate 1. The output ends of the two hydraulic lifting rods 16 are respectively fixedly connected to the outer walls of the two corner cylinders 8. The output ends of the corner cylinders 8 located around the No. 2 platform 3 are located above the positioning plate 5, and the output ends of the corner cylinders 8 located around the No. 1 platform 2 are located above the No. 1 platform 2.

[0032] More specifically, when it is necessary to clamp and limit the workpieces located on platform 2 and platform 3, simply activate the corner cylinder 8 first, so that its output end is biased to one side, so as not to obstruct the placement of the workpieces on platform 2 and platform 3. Then activate the hydraulic lifting rod 16, so that the corner cylinder 8 rises a certain distance, reducing the wear between it and the workpiece. Then activate the corner cylinder 8 again, so that its output end returns to its original position. After that, lower the hydraulic lifting rod 16 to complete the limitation of the workpiece.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the upper ends of the three supports 6 are all fixedly connected to protective shells 7, and the upper surface of the support plate 1 is fixedly connected to three other protective shells 7. The inner walls of the six protective shells 7 are all provided with storage cavities 701, and the six hydraulic lifting rods 16 are respectively located in the six storage cavities 701.

[0034] More specifically, by setting up the protective shell 7 and the storage cavity 701, the hydraulic lifting rod 16 can be protected, and at the same time, it looks relatively beautiful.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the lower side wall of the positioning disk 5 has several chip discharge ports 501, which are staggered with several chucks 4.

[0036] More specifically, by setting up the chip discharge port 501, the waste chips generated during processing can be discharged.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
