specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 1-3 This embodiment will be described.

[0009] A pump body steel ball press machine, the equipment is a vertical structure, the machine tool table is composed of a bench (12), a work table (41) and a frame (1) on the table, and the bench (12) has four An adjustable foot (13) that can be adjusted horizontally, the workbench is the main support part of the equipment; the workpiece (39) is positioned through the positioning sleeve (38) and the positioning pin (8), and placed on the fixture bottom plate (6) On the top, it is tightened by two cylinders (7); the fixture is equipped with an auxiliary support for bearing the force of the oil pump body, the auxiliary support rod (11) can move up and down along the guide sleeve (40), and the screw rod (14) is connected with the auxiliary support rod (11) , the spring (15) is installed on the screw (14), the wedge (16) is installed on the auxiliary support seat (16), and moves le...

specific Embodiment approach 2

[0010] Specific implementation mode two: combination Figure 1-3 Describe the working process of the pump body steel ball press machine.

[0011] When the pump body steel ball press is working, first place the workpiece (39) on the positioning sleeve (38) and the pin (8), and clamp it through the cylinder (7), and the auxiliary support rod (11) acts on the spring (15) contact with the workpiece (39), the spring (18) locks the auxiliary support rod (18) through the wedge (17). The steel ball automatic feeding device (23) enables the steel ball to be transported to the correct position. Pneumatic press-fitting device, the motor (29) drives the reducer (30) to rotate the ball screw (44), and under the action of the screw nut (45), drives the moving plate (25) to slide down along the guide column (2), The pressure head (37) presses the steel ball into the workpiece (39). After the steel ball is pressed in, the motor (29) reverses to make the press-fitting mechanism rise, and the...

Abstract

The invention discloses a pump body steel ball pressing fitting machine. The pump body steel ball pressing fitting machine is of a vertical structure, and is composed of a machine tool table, a steel ball automatic feeding device, a pressing fitting device and an oil pump clamp. Pressing fitting is driven through a servo motor so that it can be guaranteed that the pump body steel ball pressing fitting machine has the good accuracy, the good rigidity and the good operation stability. A pressure sensor is installed on a pressing head, and changes of displacement and pressure in the pressing fitting process can be monitored in real time. One-face-two-pin positioning is adopted in the clamp, and clamping through an air cylinder is achieved. Pressing fitting process automation is achieved, automatic feeding of a steel ball is achieved through the steel ball automatic feeding device, and the labor production rate is improved.

Description

technical field [0001] The invention belongs to assembly equipment, and is especially suitable for automatic press assembly of steel balls in oil pump bodies. Background technique [0002] The oil pump is an important component in the automobile lubrication system. Its function is to increase the oil to a certain pressure, and then forcefully press it to the moving surfaces of the various parts of the engine. A pressure limiting valve is installed on the pump body. The pressure limiting valve is a steel ball type. When the oil pressure at the outlet of the oil pump reaches a certain pressure value, the pressure acting on the steel ball overcomes the spring thrust of the pressure limiting valve, and the steel ball is pushed away. A part of lubricating oil flows directly back to the oil pan through the oil return pipe. Most of the steel balls in the existing oil pump body are manually operated, which has the problems of low efficiency and unreliable installation. Contents o...
