Description

A device for deburring end faces of cylinder head threaded through holes

technical field

Background technique

In the manufacturing process of the current vehicle engine, it is usually necessary to provide a threaded through hole on the cylinder head vacuum pump mounting surface of the engine. In order to open a threaded through hole on the cylinder head of the engine, the cylinder head N is usually processed by the process of drilling the integral carbide twist drill M shown in Figure 1 from the end face of the engine.

As shown in Figure 1, when this processing technology is used, due to the certain draft angle on the surface of the blank at the threaded through hole, the drill bit M will drill through the lowest point of the blank surface first during the process of gradually drilling through. At the same time, because the metal allowance is very thin and the rigidity is poor when drilling, a metal flake will remain at the highest point of the blank at this time, which can be regarded as a burr. If the metal flakes are not removed in time, the metal flakes may fall into the engine during the assembly process, and may cause the motor to vibrate or even bite to death during the running of the engine.

However, because the position of the burr (metal flake) is on the end face of the machining part of the tool, and the other side is the positioning surface of the fixture, the tool cannot be inserted into this position to remove the burr during the machining process. Therefore, there is an urgent need for a device capable of removing the deburring of the end face of the threaded through hole of the cylinder head.

In order to solve the above problems, some researchers have conducted research and have designed the following solutions:

1. Use a fork-shaped elastic deburring knife to deburr the threaded through hole. After the fork-shaped elastic deburring blade passes through the threaded through hole, it relies on the elastic expansion of the knife rod itself, and deburrs and chamfers the opening of the threaded through hole when it moves backward. When the fork-shaped elastic deburring blade continues to move backward, as the cutting force gradually increases, it will overcome the elastic force of the knife rod itself, so that the chamfering blade shrinks, so as to ensure that the knife rod withdraws from the through hole.

2. Deburring with a centrifugal force type end face deburring knife.

3. During the final inspection, the operator manually removes the burrs with a file.

4. Add an automatic deburring robot, and use the industrial robot to hold the electric brush to deburr the threaded through hole of the cylinder head.

However, it should be noted that in actual application, the inventors found that these four technical solutions still have certain defects. device. Using these two solutions at the same time, the tool change time of adding a deburring tool is about 3 seconds, the processing time is about 3 seconds, and the stand-alone beat loses a total of 6 seconds.

From the outside, when the above solution 3 is adopted, there are problems such as high labor intensity of workers, poor deburring effect, and omission of deburring. In addition, when adopting the above-mentioned solution 4, there are problems such as high technical difficulty and high investment cost.

It can be seen that there is still a lack of a technical solution that can easily and effectively remove the burrs on the end face of the threaded hole of the cylinder head. Therefore, in order to solve the above problems in the prior art, the inventor has designed a deburring device for the end face of the threaded hole in the cylinder head. , the device can easily and effectively remove the burrs at the openings of the threaded through holes of the cylinder head.
