Description

Technical Field

[0001] The utility model belongs to the technical field of automatic press-fitting machines, and in particular relates to an automatic steel ball press-fitting machine capable of automatically turning over. Background Art

[0002] During the production process of hydraulic valves, some process holes need to be processed to facilitate internal reversing. After processing, these process holes need to be sealed by steel ball press-fitting to ensure the sealing of the hydraulic valve. Since these process holes are distributed on different surfaces of the hydraulic valve, and the number and position of process holes on different press-fitting surfaces are different.

[0003] In the traditional hydraulic valve steel ball press-fitting process, a series of tedious tasks such as manual turning over, tooling matching, steel ball insertion, and press-fitting are required, which have problems such as slow speed, low efficiency, and great safety hazards. In addition, during the operation of the steel ball automatic press-fitting machine, when the laser displacement sensor detects the height of the press-fitting block, reflection will occur when the laser shines on the press-fitting hole, resulting in inaccurate height measurement; and when the laser scans from the plane to the height of the press-fitted part, the height difference data in the middle will be collected, resulting in inaccurate height measurement. Therefore, an automatic steel ball press-fitting machine that can automatically turn over is needed to solve the above problems. Utility Model Content

A worm is connected, the worm wheel is meshed with the worm, a second motor is arranged at the rotation point of one end of the worm, a fixed block is fixedly connected to one side of the machine platform, a cylinder is fixedly connected to the upper surface of the fixed block, a moving block is fixedly connected to the top of the cylinder, an electric push rod is fixedly connected inside the moving block, one end of the electric push rod is fixedly connected to the third motor, an electromagnetic block is fixedly arranged on the output shaft of the third motor, a control unit is fixedly arranged on one side of the machine platform, a displacement device is arranged on the machine platform, an automatic pressing unit is displaced on the displacement device, both sides of the automatic pressing unit are rotatably connected to rotating plates, a fourth motor is arranged at the rotating point of the rotating plate, a through slot is penetrated through the rotating plate, a vertical gravity block is rotatably arranged inside the through slot, and a detection unit is fixedly arranged on the oblique side of the vertical gravity block.

During this period, if the workpiece needs to be changed, the clamping plate will be driven to rotate through the transmission of the worm and the worm wheel under the operation of the second motor, thereby driving the clamped workpiece to change its surface and rotate. When the workpiece needs to change its side, the electric push rod will drive the electromagnetic block to extend to the surface of the workpiece and absorb the workpiece. Then, under the operation of the third motor, the electromagnetic block will drive the workpiece to rotate sideways to change its surface, thereby realizing automatic turning over of all surfaces of the workpiece. In this process, The control unit performs operation and adjustment, which is more labor-saving and efficient than manual turning over. In addition, by arranging two detection units on both sides of the automatic pressing unit, the detection laser can detect from different directions, which helps to avoid the problem of data difference caused by a single detection unit measuring multiple pressed parts. The fourth motor can drive the turn plate to rotate to block a certain amount of light, which helps to reduce the impact of light reflection, and the vertical gravity block will always remain in a vertical state through rotation, so that the detection unit will not be affected by too much rotation of the turn plate, thereby helping to ensure a certain detection effect and having strong practicality.

The operation can be adjusted by controlling the unit, which is more labor-saving and efficient than manual turning over. In addition, by arranging two detection units on both sides of the automatic pressing unit, the detection laser can detect from different directions, which helps to avoid the problem of data difference caused by a single detection unit measuring multiple pressed parts.
