Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve body processing technology, specifically a lathe for precision machining of proportional valves. Background Technology
[0002] A proportional valve is a new type of hydraulic control device. It replaces the original control part of ordinary pressure valves, flow valves, and directional valves with a proportional electromagnet. It can continuously and proportionally control the pressure, flow rate, or direction of oil flow remotely according to the input electrical signal. Proportional valves generally have pressure compensation performance, and the output pressure and flow rate can be unaffected by load changes.
[0003] The drilling device for processing the valve body of a proportional valve described in Chinese patent CN213352708U, by setting up a support platform, a fixing mechanism, a drilling mechanism and a power mechanism, makes it easy to fix the valve body and facilitates drilling holes on different surfaces of the valve body at the same time.
[0004] However, this drilling device only achieves this by setting a drilling mechanism corresponding to the number of drilling surfaces. When drilling is required on all four sides of the valve body, the corresponding drilling device needs to be equipped with drilling mechanisms in the front, back, left, and right. The actual drilling position is not easy to adjust due to this structural design, the cost is relatively high, and the practicality needs to be improved. Therefore, we propose a proportional valve precision machining lathe to solve the above problems. Utility Model Content

[0013] Preferably, a hydraulic chamber is fixedly connected to the end of the connecting pipe away from the assembly table, and a push plate is built into the hydraulic chamber, with the push plate slidably connected to the inner wall of the hydraulic chamber.
[0014] Preferably, a telescopic cylinder is provided on the side of the push plate away from the hydraulic chamber, and the output end of the telescopic cylinder is fixedly connected to the push plate.
[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0016] In this invention, the proportional valve is placed on top of the turntable. Multiple moving frames, under the action of elastic elements, fix the proportional valve in place with a clamping plate, ensuring its stability during processing. The turntable rotates by a telescopic cylinder pushing a push plate within the hydraulic chamber. The push plate compresses hydraulic oil, causing it to enter one end of the arc groove through a connecting pipe, pushing the moving seat to slide within the arc groove. The connecting roller at the top of the moving seat is fixedly connected to the bottom of the outer ring of the turntable, thereby driving the turntable to rotate. The turntable is rotatably connected to the fixed roller on the mounting table via a bottom mounting groove, ensuring rotational stability. Simultaneously, the rubber ring on the moving seat slides against the wall of the arc groove, and the sealing gaskets on both sides of the arc groove effectively prevent hydraulic oil leakage. An air valve at one end of the arc groove balances the air pressure.
[0017] This control component is simple and convenient to operate, improving work efficiency. The hydraulically controlled turntable rotation offers high precision, accurately controlling the proportional valve's direction to meet finishing requirements. Multiple moving frames are evenly distributed around the turntable axis, further enhancing the stability of the proportional valve. The overall design is reasonable, providing a reliable guarantee for the finishing of the proportional valve. Attached Figure Description
