Description

Technical Field

[0001] The utility model belongs to the technical field related to steel ball processing, in particular to a hydraulic pressure regulating structure of a steel ball grinding machine. Background Art

[0002] The steel ball grinding machine is an important equipment for processing rolling elements such as steel balls, ceramic balls, and plastic balls. It is widely used in bearing companies, professional rolling element manufacturers, etc. The steel ball workpiece of the vertical steel ball equipment is between the upper ball plate (grinding wheel) and the lower ball plate. The upper ball plate (grinding wheel) is installed on the upper grinding plate. The pressure device presses the steel ball, and the upper and lower grinding discs rotate relative to each other to achieve the purpose of processing the steel ball. Therefore, it is necessary to generate extrusion pressure on the ball plate through a hydraulic pressure regulating structure to speed up the grinding efficiency of the steel ball. However, it still has the following disadvantages in actual use:

[0003] The hydraulic pressure regulating structure of the steel ball grinding machine directly uses hydraulic oil for extrusion. During the extrusion process, the oil cylinder is usually directly extruded. During the extrusion process, different hydraulic cylinders are controlled by different oil circuits. When working, the pressure in different oil circuits is different, which will cause the pressure on the ball plate of the grinding machine to be unbalanced, affecting the grinding effect of the steel ball;

[0004] The hydraulic pressure regulating structure of the steel ball grinding machine is directly transmitted to the ball plate through the hydraulic cylinder, causing unbalanced pressure at different positions on the ball plate. When pressing on the ball plate, it is easy to cause deformation of the upper ball plate, affecting the durability of the ball plate. Utility Model Content

[0005] The purpose of the utility model is to provide a hydraulic pressure regulating structure of a steel ball grinding machine. By arranging a fixed plate, a transfer shell, a hydraulic cylinder and a top mounting plate, the utility model solves the problem that the hydraulic pressure regulating structure of the steel ball grinding machine easily causes pressure imbalance on the ball plate during pressure regulation, thereby affecting the grinding effect of the steel ball, and the uneven pressure on the ball plate easily causes deformation of the ball plate.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a hydraulic pressure regulating structure of a steel ball grinding machine, comprising a fixed plate, a transfer shell, a hydraulic cylinder and a top mounting plate, wherein the transfer shell is fixed at the top center of the fixed plate, the four side surfaces of the lower part of the transfer shell are all fixedly connected with connecting pipes, the ends of the connecting pipes away from the transfer shell are all fixedly connected with the hydraulic cylinder, a lifting piston is movably connected in the hydraulic cylinder, a top mounting plate is arranged above the transfer shell, when working, the hydraulic cylinder is fixed therein through the fixed plate, the hydraulic oil input therein is transferred through the transfer shell, and is transported to the hydraulic cylinder through the connecting pipe, the fixing ring is pressed down in the hydraulic cylinder, and the fixed plate is installed in a suitable position through the top mounting plate.

[0008] Furthermore, four fixing holes are formed in a circular array on the outer side of the transfer shell in the fixing plate, and the four hydraulic cylinders are respectively fixed in the four fixing holes, and the fixing plate fixes the hydraulic cylinders through the fixing holes.

[0009] Furthermore, a fixing ring is provided below the fixing plate, an opening is provided in the fixing ring, and mounting holes are provided vertically in a circular array in the fixing ring outside the opening. The fixing plate is provided with the grinding ball plate for mounting via the mounting holes.

[0010] Furthermore, a pressure gauge is fixedly connected to the center of the top of the transfer shell, and fixed pipes are fixedly connected to the corners of one side of the transfer shell. The transfer shell determines the pressure in the transfer shell through the pressure gauge.

[0011] Furthermore, a pressure rod is fixed to the bottom end of the lifting piston, and the bottom end of each pressure rod is fixed to the top end surface of the fixing ring. After the lifting piston receives pressure through the pressure rod, it is pressed onto the fixing ring.

[0014] The utility model solves the problem that the hydraulic pressure regulating structure of the steel ball grinding machine easily causes pressure imbalance on the ball plate during pressure regulation, thereby affecting the grinding effect of the steel ball, by arranging a fixed plate, a transfer shell and a hydraulic cylinder. When the fixed plate descends, the upper ball plate fixed by the fixed ring contacts the lower ball plate, and pressure is generated. When the pressure needs to be adjusted, the hydraulic oil is transported to the fixed pipe through an external pipeline, and then transported to the transfer shell through the fixed pipe, and then transported to four fixed pipes through the transfer shell, and then transported to four hydraulic cylinders through the four fixed pipes, so that the places where the ball plate generates pressure are evenly divided into four, thereby preventing the upper ball plate from receiving pressure imbalance and ensuring the grinding effect of the steel ball.

The transfer shell 3 is fixed at the top center of the fixed plate 1. When the fixed plate 1 is working, the transfer shell 3 is fixed thereon, and the hydraulic oil entering therein is transferred through the transfer shell 3. The four side surfaces of the lower part of the transfer shell 3 are all fixedly connected with connecting pipes 303.

The ends of the connecting pipes 303 away from the transfer shell 3 are all fixedly connected with the hydraulic cylinder 4. A lifting piston 401 is movably connected in the hydraulic cylinder 4. After the hydraulic oil is input into the hydraulic cylinder 4, the pressure that presses the lifting piston 401 downward is generated. A top mounting plate 5 is arranged above the transfer shell 3, and the top mounting plate 5 installs the fixed plate 1 on an external lifting device.

[0026] Specifically, four fixing holes 101 are formed in a circular array on the outer side of the transfer shell 3 in the fixing plate 1 , and the four hydraulic cylinders 4 are fixed in the four fixing holes 101 respectively.

[0027] Furthermore, a fixing ring 2 is provided below the fixing plate 1, and an opening 201 is provided through the fixing ring 2. Mounting holes 202 are provided vertically through the fixing ring 2 outside the opening 201 in a circular array. The fixing plate 1 is installed on the top of the ball plate of the steel ball grinding ball through the mounting holes 202, so that when the fixing plate 1 descends, the ball plate is driven to descend.

[0028] Furthermore, a pressure gauge 302 is fixedly connected to the center of the top of the transfer shell 3, and a fixed pipe 301 is fixedly connected to the corners of one side of the transfer shell 3.
