[0002] Currently, for the shell end covers of new products in production, according to customer requirements, the parts need to be machined. The originally designed hydraulic tooling is relatively simple, and the clamping and positioning are not ideal. During the machining process of the parts, the positioning is unstable, resulting in unqualified machining dimensions of the part products. Therefore, there is an urgent need in the market to develop a hydraulic tooling for machining shell end covers to help people solve the existing problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a hydraulic tooling for machining shell end covers, so as to solve the problem that in the production of the current new product shell end covers, according to customer requirements, the parts need to be machined. The originally designed hydraulic tooling is relatively simple, the clamping and positioning are not ideal, and the positioning is unstable during the machining process of the parts, resulting in unqualified machining dimensions of the part products as mentioned in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A hydraulic tooling for machining shell end covers, including a bottom plate, on which a hydraulic tooling is provided. The hydraulic tooling includes a hydraulic fixing system, a positioning and supporting system, and a limiting system. A shell end cover body is supported and fixed in the hydraulic fixing system, the positioning and supporting system, and the limiting system. The hydraulic fixing system includes four groups of hydraulic clamping mechanisms. Each hydraulic clamping mechanism includes an oil delivery seat and an oil cylinder. The oil delivery seat is fixedly connected to the bottom plate. A connecting seat is fixedly installed on the oil delivery seat. A connecting leg is rotatably connected to the connecting seat. A piston rod is slidably connected to the oil cylinder. The top end of the piston rod is rotatably connected to a chuck. The middle part of the chuck is rotatably connected to one end of the connecting leg.

[0005] Through the above technical solution, this finished part machining hydraulic tooling is specially designed according to the size of the shell end cover body. This tooling is designed according to the characteristics of the part, uses the stable holes and surfaces on the part for positioning, enables the shell end cover body to be effectively positioned and supported in the positioning and supporting system and the limiting system, and then uses the hydraulic fixing system for pressing and fixing to maintain the stability of the product during the machining process, thereby ensuring the stability of the part dimensions. This hydraulic tooling can effectively improve the stability of part measurement compared with the original technology, and employees will not damage the surface of the part during the operation process. The produced parts have high dimensional stability. Its designed hydraulic automatic clamping can make it more convenient for employees to pick up the parts.

[0006] In a preferred example of the present invention, it can be further configured that: A hoisting system is fixedly installed on the bottom plate. The hoisting system includes four lifting rings.

[0007] Through the above technical solution, the integral bottom plate can be hoisted by using the hoisting system.

[0008] In a preferred example of the present invention, it can be further configured that: legs are fixedly installed below the bottom plate, there are four legs, a preset end cover hole is arranged inside the bottom plate, and the outer shape of the preset end cover hole is similar to the outer edge shape of the housing end cover body.

[0009] Through the above technical solution, by using the design of the preset end cover hole, the bottom of the housing end cover body can be made not to contact the bottom plate, thereby ensuring the flexibility of space utilization, and the space in the vertical direction will not interfere with the housing end cover body, facilitating quick installation and fixation. At the same time, the outer shape can be used to facilitate observing the installation direction of the housing end cover body, improving the convenience of use.

[0010] In a preferred example of the present invention, it can be further configured that: an oil circuit system is arranged below the bottom plate, and the oil circuit system is communicated with the oil cylinder.

[0011] Through the above technical solution, the oil cylinder is supplied with oil through the oil circuit system to control the synchronous operation of all oil cylinders, thereby improving the reliability of the clamping action on the housing end cover body.

[0012] In a preferred example of the present invention, it can be further configured that: the positioning and supporting system includes a first positioning and supporting seat, a second positioning and supporting seat, and a second positioning and supporting seat. Positioning protrusions are telescopically connected above the first positioning and supporting seat and the second positioning and supporting seat, and a positioning protrusion is fixedly connected to the second positioning and supporting seat.

[0013] Through the above technical solution, the first positioning and supporting seat, the second positioning and supporting seat, and the second positioning and supporting seat are used to support the housing end cover body, and positioning is carried out by using the positioning protrusions to prevent misalignment when placing the housing end cover body. At the same time, the positioning protrusions above the first positioning and supporting seat and the second positioning and supporting seat are telescopic, which is convenient for finding the position during use. And when pressing the housing end cover body, the force can be on the positioning and supporting seat, thereby preventing the holes on the housing end cover body from being damaged, improving the safety and reliability of use.

[0014] In a preferred example of the present invention, it can be further configured that: the limiting system includes a first limiting seat, a second limiting seat, and a third limiting seat, and positioning arcs are arranged inside the tops of the first limiting seat, the second limiting seat, and the third limiting seat.

[0015] Through the above technical solution, the first limiting seat, the second limiting seat, and the third limiting seat are used for auxiliary positioning to prevent excessive displacement of the housing end cover body during processing.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention specially designs this finished part machining hydraulic tooling according to the size of the housing end cover body. This tooling is designed according to the characteristics of the part, uses the stable holes and surfaces on the part for positioning, enables the housing end cover body to be effectively positioned and supported in the positioning support system and the limit system, and then uses the hydraulic fixing system for pressing and fixing to maintain the stability of the product during the machining process, thereby ensuring the stability of the part size. This hydraulic tooling can effectively improve the stability of part measurement compared with the prior art, and employees will not damage the part surface during the operation process. The produced parts have high size stability. Its designed hydraulic automatic clamping can make it more convenient for employees to pick up the parts.

[0018] 2.
