Bi-directional bearing supporting diamond roller dressing device

Abstract

The invention discloses a bi-directional bearing supporting diamond roller dressing device. The structure comprises shafts and a diamond roller, wherein the shafts comprise a front bearing supporting sleeve mounting shaft, a diamond roller mounting shaft, a back bearing supporting sleeve mounting shaft and a synchronous pulley mounting shaft; the diamond roller mounting shaft is a cone-shaped shaft; the diamond roller is connected with the diamond roller mounting shaft in a matching and sleeving manner; a fastness adjustment locking end cover is arranged at the back end of the diamond roller; a front bearing supporting sleeve is mounted on the front bearing supporting sleeve mounting shaft; a locking end cover is arranged at the free end of the front bearing supporting sleeve; a back bearing supporting sleeve is arranged on the back bearing supporting sleeve mounting shaft; a locking end cover is arranged at the back end of the back bearing supporting sleeve; a synchronous pulley is arranged on the synchronous pulley mounting shaft; and a lock nut is arranged at the free end of the synchronous pulley. According to the dressing device, the diamond roller is supported through bi-directional bearings, so that the possibility of vibration in the radial direction and the axial direction is prevented, the stability is improved, the qualified rate of produced valves is guaranteed to be high, the rejection rate is decreased, the quality cost is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a dressing device, in particular to a two-way bearing supported diamond wheel dressing device. Background technique [0002] The valve lock clip groove plays a very important role when the engine is working. (When the engine is working, there is a groove on the valve, and then there is a valve spring to make the valve return. Use the lock clip to clamp the valve, and install the valve lock clip on the valve groove In this way, when the valve is opened, not only will it not fall, but it can also return to its position under the action of the spring. Only in this way can the engine work normally.) When the engine is working, the valve lock clip is stuck in the lock clip slot of the valve to block the spring, so that The spring drives the valve to return to close the intake and exhaust holes.

AI Technical Summary

Problems solved by technology

[0003] In the usual processing of the valve lock groove, since the diamond wheel is trimmed using a single-sided bearing support and fixed mode, this device is prone to radial swing and instability during the trimming process, and the groove shape of the processed lock groove is abnormal. Large or small, or the groove depth is different. If multi-groove processing, the groove shape, groove diameter, and size of the same valve will be inconsistent. If there is a valve with an out-of-tolerance lock groove size during mass production, install it in the engine. , which will affect the life of the engine in the slightest, and cause the overall failure of the engine in severe cases.

The main problems in the processing of this single-support fixed dressing wheel: 1. High cost

Since the processing of this process is a finished product process, the processing of the lock clip groove cannot be reworked, so the cost caused by this process is very high

2. Affect production efficiency and production quality

This single-support dressing device, due to the poor stability of the diamond wheel, causes the shaft and bearing to wear quickly. The shaft and bearing must be replaced after 10 days of use (two-month replacement for double-support), and each replacement and adjustment takes half a day. , if the groove shape or groove diameter is found to be unqualified during the process, a special person will be sent to sort 100% of the processed products, which will seriously affect the production efficiency and production quality

3. Increased potential risks to customers

Since the lock clip groove inspection is a random inspection item, if one or more unqualified products flow into the OEM due to instability in the processing process, there will be immeasurable risks after installation
