Description

Technical Field

[0001] The utility model belongs to the technical field of deburring equipment, in particular to a hydraulic valve burr grinding device. Background Art

[0002] Hydraulic valves are prone to burrs during machining, which have a significant impact on the performance and reliability of the hydraulic valve system. Therefore, effective measures must be taken to prevent and remove burrs during machining.

[0003] In the prior art, a hydraulic valve plate deburring device has been disclosed, with the document number CN220481167U. The device includes a main support mechanism and a deburring mechanism. The main support mechanism includes a table and a frame. The table is mounted above the frame, and a positioning member is provided above the table. The deburring mechanism includes a bracket, a cylinder, a motor, a grinding disc, and a grinding head. The bracket is disposed above the table, the cylinder is mounted at the top of the bracket, and the motor is mounted at the end of the cylinder output rod. The cylinder output rod end pushes the motor downward, thereby driving the grinding disc and grinding head downward until the grinding head penetrates the valve plate hole to perform deburring and grinding operations, and the grinding disc and the upper surface of the valve plate are simultaneously deburred at the junction of the grinding disc and the valve plate surface.

[0004] However, in the above scheme, the cam and the grinding head are coaxially arranged. Only when the lower end of the corresponding hole of the valve block is inserted into the outside of the cam, the downward-moving grinding head shell can accurately penetrate into the hole that needs to be polished and deburred. Therefore, only one hole can be deburred at a time. When there are multiple holes on the hydraulic valve and most of the holes have burrs that need to be removed, the corresponding holes of the hydraulic valve need to be inserted into the outside of the cam one by one, which is more troublesome and inefficient.

The two clamping plates 12 can slide along the length direction of the second slide groove 10 or the third slide groove 11. The area between the two clamping plates 12 is the hydraulic valve placement area. In order to adapt to the size of different valve blocks, that is, the two clamping plates 12 can Hydraulic valves 29 of different sizes are positioned, and a locking assembly is set on the bottom lining plate 8.

The speed of the driving motor 19 is not high. When the driving motor 19 is working, the grinding head 23 rotates with the turntable. When the hydraulic valve 29 rises to the maximum height, the lower ends of some grinding heads 23 can contact the holes on the upper surface of the hydraulic valve 29, and the other parts of the grinding heads 23 are located in the gap between two adjacent holes. At this time, the grinding head 23 in the gap between the two adjacent holes moves upward, and the compression return spring 24 undergoes a certain deformation.
