Problems solved by technology
[0007] According to the characteristics of the asymmetric and special-shaped structure of the plunger sleeve, the problems of poor clamping positioning accuracy and difficult counterweight are solved. The invention provides a balance device for machining the inner hole of the plunger sleeve. The counterweight scheme of the device is adjusted The direction of the counterweight coincides with the center of gravity in the vertical direction, and the position of the counterweight in this direction is controlled to realize the balance between the plunger sleeve and the balance device in the circumferential direction. The positioning and clamping scheme of the device is through the positioning of the stop , thread locking, top wire anti-loosening, the device has the characteristics of high positioning accuracy, easy clamping operation, accurate counterweight, convenient adjustment, strong versatility, etc., suitable for mass production

Embodiment Construction
[0029] exist Figure 5 Among them, a balance device for machining the inner hole of a plunger sleeve, characterized in that the device includes: a balance mandrel 1, a balance disc 2, a locking ring 3, a counterweight 4, a plunger sleeve 5, a flange base6. The inner hole of the plunger sleeve 5 is coaxial in the circumferential direction, the upper end surface of the plunger sleeve 5 is perpendicular to the inner hole of the plunger sleeve, the balance mandrel 1 is a revolving body, and each circular surface is coaxial in the circumferential direction, perpendicular to each end surface, The gap between the plunger sleeve 5 and the balance mandrel 1 is positioned by a spigot, and the thread is locked. Through the spigot positioning, the coaxiality requirements of the positioning are guaranteed, and the verticality requirements are also guaranteed. Through the screw locking, the operation is simple and the shortening is assisted. Working hours: The locking ring 3 is a centrally...

The invention relates to a balancing device for processing an inner hole of a plunger sleeve, which is particularly suitable for improving the precision processing and positioning precision and high-speed rotation precision of the inner hole of the plunger sleeve in an oil supply system, and is particularly suitable for the precision grinding, clamping and positioning requirements of the inner hole of the plunger sleeve. According to the working principle of the device, the balancing state of the balancing device in the circumferential direction is achieved by adjusting the position and mass of the balancing weight in the vertical direction of the gravity center and the rotation center of the balancing device. The device has the characteristics of high positioning precision, easiness in clamping operation, accurate counterweight, convenience in adjustment, high universality and the like, and is suitable for being applied to batch production.
Description
technical field [0001] The invention relates to a balance device for machining the inner hole of a plunger sleeve, which is especially suitable for improving the precision machining positioning accuracy and high-speed rotation accuracy of the inner hole of the plunger sleeve in the oil supply system, and is especially suitable for the precision grinding of the inner hole of the plunger sleeve Processing clamping positioning needs. Background technique [0002] With the continuous improvement of the machining accuracy of the key parts of the oil supply system, higher requirements are put forward for the machining accuracy of the plunger couple. The plunger couple is a precision couple with a small fit clearance and a long contact distance. The core component to realize its function. Among them, the machining accuracy and surface quality of the plunger hole seriously affect the reliability of the gap control of the plunger couple and the reliability of high-frequency reciproc...
