Problems solved by technology
However, for valve body parts, because the internal valve hole is connected to multiple oil grooves, the burrs at the junction of the hole and the oil groove are difficult to remove by hand with a scraper or sandpaper, and it is easy to scratch the hole and the hole wall
When the hole or groove is small, the scraper or hand cannot reach to deburr the hole
If the burr in the inner hole of the valve body parts is not removed cleanly, the movement of the valve core will be blocked, which will cause the product performance to be unstable or unable to work

Embodiment Construction
[0017] Embodiments of the present invention: with image 3 For example, combine figure 1 Be explained.
[0018] First, analyze the structure between each valve hole and the oil groove inside the valve body, focusing on the relevant dimensions such as the diameter of the valve hole φDa, the depth of the valve hole La2, and the width of the oil groove La1;
[0019] Second, design and manufacture special tools for removing burrs at the inlet and outlet of valve holes;
[0020] 1. Tool design
[0021] Such as figure 1 As shown in , the tool adopts a one-piece structure, and there is a slot in the middle of the tool bar. The slotted part of the tool bar has strong elasticity.
[0022] The relevant dimensions of the tool are designed as follows:
[0023] (1) The value of the cutter head diameter φD is the valve body aperture φDa+(1mm~4mm);
[0024] (2) The value of the diameter of the cutter bar φD1 is (0.5~0.8)×the diameter of the cutter head φD;
[0025] (3) The value of th...

The invention discloses a processing method for removing burrs at holes in a valve body. The method comprises the following process flows: 1. analyzing the structure between each valve hole in a valve body and an oil groove and mainly considering the relevant dimensions such as the valve hole diameter, the valve hole depth, the oil groove width and the like; 2. designing and manufacturing a special tool for removing the burrs at the inlets and outlets of the valve holes; and 3. using the processed tool to remove the burrs at the inlets and outlets of the valve holes in the valve body. The method has the following beneficial effects: the burrs at the joints of the valve holes in the valve body and the oil groove can be simply, conveniently and quickly removed by adopting the method, thus alleviating the labor intensity of workers, improving the production efficiency and ensuring the product quality; and the method has the advantages of simpleness in operation, low cost and wide range of application.
Description
technical field [0001] The invention relates to a processing method for removing burrs from an orifice in a valve body, belonging to the field of mechanical processing. Background technique [0002] The processing of round holes includes drilling, reaming, boring, reaming, extrusion holes, etc. After processing, burrs are generated at the entrance and exit of the hole. The current method of deburring the orifice is mainly to manually deburr with a scraper or sandpaper. However, for valve body parts, since the internal valve hole is connected to multiple oil grooves, the burrs at the junction of the hole and the oil groove are difficult to remove by hand with a scraper or sandpaper, and it is easy to scratch the orifice and the hole wall. When the hole or groove is small, the scraper or hand cannot reach it, and the hole burr cannot be removed. If the burr in the inner hole of the valve body parts is not removed cleanly, the movement of the valve core will be blocked, which...
