Controlling mechanism for honing liquid pump

Abstract

The invention discloses a controlling mechanism for a honing liquid pump. The mechanism comprises a plunger device and a controlling device, wherein the controlling device is installed at one end of the plunger device and controls the plunger device; and honing liquid flows in and out through a joint device and the plunger device. Compared with the prior art, the controlling mechanism for the honing liquid pump has the advantages as follows: 1, by the aid of suction force of a separation membrane of the plunger device and under the action of spring force, a plunger moves forwards and backwards to push the separation membrane, so that control of feeding and discharging volume of the honing liquid is realized, the structure is simple, and the cost is reduced; and 2, a ratchet wheel is controlled to rotate through a flow regulation wheel, so that the ratchet wheel drives a cam wheel to move, the position of the plunger is controlled, the function of regulating the flow of the honing liquid is achieved, the cost is reduced, and the working efficiency is improved to a certain extent.

Description

technical field [0001] The invention relates to a honing feeding device, in particular to a honing liquid pump control mechanism. Background technique [0002] The grinding liquid pump is a special pump for honing feeding. At present, the plunger pump is used in the market. The cam is used to drive the plunger to reciprocate. supply. However, the existing structure can only control the in and out of the honing fluid, but cannot effectively control the flow of the honing fluid. When a large flow of honing fluid is not required, supplying a large flow of honing fluid will cause waste of the honing fluid and high cost, which cannot meet the requirements of reducing production costs. need. [0003] In the current market, the plunger is directly fixed on the inner ring of the cam, and the rotation of the cam drives the reciprocating movement of the plunger, so the cam and the plunger wear a lot, the life is short, the cost is high, and the work efficiency and economic benefits ...

AI Technical Summary

Problems solved by technology

However, the existing structure can only control the entry and exit of the honing fluid, and cannot effectively control the flow of the honing fluid. When there is no need for a large flow rate, the honing fluid with a large flow rate will be supplied, resulting in a waste of honing fluid and high cost, which cannot meet the requirements of reducing production costs. need

[0003] In the current market, the plunger is directly fixed on the inner ring of the cam, and the cam rotates to drive the plunger to reciprocate, so that the cam and the plunger wear a lot, the life is short, the cost is high, and the work efficiency and economic benefits cannot be improved.
