Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plunger assembly, in particular to an assembly device for small parts inside a plunger. Background Art
[0002] The plunger has to reciprocate in the cylinder, so its movement is large and it needs to withstand huge friction during operation. Therefore, the plunger requires high hardness, wear resistance, service life and high precision.
[0003] In the prior art, when assembling the plunger, due to the large number of parts, it is important to prevent missing or wrong assembly, and the internal parts are easily reversed during the assembly process.
[0004] Therefore, we propose an assembly device for small parts inside the plunger to solve the problem that the internal parts are easily reversed during the assembly process. Utility Model Content
[0005] The purpose of the utility model is to provide an assembly device for small parts inside a plunger to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembly device for small parts inside a plunger, comprising a positioning hole plate, a clamping block is provided above the positioning hole plate, a plunger sleeve is provided above the clamping block, a plunger tooling is provided above the plunger sleeve, a vacuum pipe suction nozzle is provided at the center position of the plunger sleeve and the plunger tooling, the lower part of the vacuum pipe suction nozzle is adsorbed and connected to an oil inlet plate, a ceramic ball is provided below the oil inlet plate, and a spring is provided on the side of the ceramic ball.
[0007] Preferably, an oil outlet valve is placed on the positioning hole plate, and a small part inside the plunger is connected above the oil outlet valve.
[0008] Preferably, the small parts in the plunger include a spring seat, a spring, a reducer, a steel ball, and a ceramic ball. The small parts in the plunger are assembled in the order of the spring seat, the spring, the reducer, the steel ball, and the ceramic ball using external automation equipment.
[0009] Preferably, the plunger tooling clamps the plunger sleeve.
[0010] Compared with the prior art, the utility model has the following beneficial effects: the oil inlet plate is adsorbed by the vacuum pipe suction nozzle, and the plunger tooling clamps the plunger sleeve, and the plunger sleeve and the oil inlet plate are rotated and screwed into the oil outlet valve from top to bottom. During this top-down assembly process, the vacuum pipe suction nozzle, under the action of the spring, the oil inlet plate always presses the steel ball, spring and spring seat to prevent the parts from being reversed.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] Please refer to 1. An embodiment of the utility model is: an assembly device for small parts inside a plunger, including a positioning hole plate 1, a clamping block 2 is provided above the positioning hole plate 1, a plunger sleeve 3 is provided above the clamping block 2, a plunger tooling 4 is provided above the plunger sleeve 3, a vacuum pipe suction nozzle 5 is provided at the center of the plunger sleeve 3 and the plunger tooling 4, the lower part of the vacuum pipe suction nozzle 5 is adsorbed and connected to an oil inlet plate 6, a ceramic ball 7 is provided below the oil inlet plate 6, a spring 8 is provided on the side of the ceramic ball 7, the vacuum pipe suction nozzle 5 provides an adsorption force, so that the positions of the oil inlet plate 6 and the vacuum pipe suction nozzle 5 are relatively fixed, at this time, due to the elastic recovery of the spring 8 upward, the small parts inside are located below the oil inlet plate 6 and the ceramic ball 7, and the small parts inside are squeezed.
[0015] The oil outlet valve is placed on the positioning orifice plate 1, and the top of the oil outlet valve is connected to a small part in the plunger. The position of the oil outlet valve is fixed by the positioning orifice plate 1, which is convenient for positioning and automatic equipment to install parts.
[0016] The small parts inside the plunger include a spring seat, a spring 8, a reducer, a steel ball, and a ceramic ball 7. The small parts inside the plunger are assembled in the order of the spring seat, the spring 8, the reducer, the steel ball, and the ceramic ball 7 using external automated equipment. The automated equipment used is existing equipment, and the installation is performed in sequence to effectively prevent missing or incorrect installation.
[0017] The plunger tooling 4 clamps the plunger sleeve 3, and the plunger tooling 4 is used to rotate the oil inlet plate 6 and screw it onto the oil outlet valve.
[0018] Working principle: When in use, the automation equipment places the oil outlet valve on the positioning hole plate 1, clamps the oil outlet valve with the clamping block 2, and assembles the spring seat, spring 8, reducer, steel ball, ceramic ball 7 parts one by one. The vacuum pipe suction nozzle 5 adsorbs the oil inlet plate 6, and at the same time the plunger tooling 4 clamps the plunger sleeve 3, and rotates the plunger sleeve 3 and the oil inlet plate 6 from top to bottom and screws them onto the oil outlet valve. In this assembly process from top to bottom, the vacuum pipe suction nozzle 5 is under the action of the spring 8, and the oil inlet plate 6 always presses the steel ball, spring 8 and spring seat to prevent the parts from being reversed.
