For example, the valve is sucked by an atmospheric pressure suction cup, and then manually lifted up and dropped with force, so that the valve and the valve seat are collided and ground. However, in this process, the operator can only grind one or two valves at a time, which has high labor costs and low operating efficiency. Summary of the invention

[0004] In view of the shortcomings of the prior art mentioned above, the purpose of the present utility model is to provide an air valve grinding device, which is simple to operate, easy to use, can save labor costs, and has high operating efficiency. It is used to solve the problems of low grinding efficiency and high labor costs of air valve grinding tooling in the prior art.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides an air valve grinding device, including a support seat, on which a valve support plate for supporting the air valve is slidably provided, and the air valve support plate can slide in a vertical direction; a driving mechanism, the driving mechanism including a driving source, a rotating shaft and a cam, wherein the rotating shaft is rotatably arranged on the support seat, the driving source is used to drive the rotating shaft to rotate, the cam is fixedly arranged on the rotating shaft and is located below the air valve support plate, the cam includes a base circle portion and a protruding portion, based on the rotation of the cam, the protruding portion can lift the air valve support plate from a starting point to a highest point, and the base circle portion can make the air valve support plate located at the highest point freely fall to its starting point.

[0006] Preferably, the support seat is provided with a slide groove extending in a vertical direction, and the air valve support plate is embedded in the slide groove.

[0007] Preferably, the driving source includes a motor, and the motor is connected to the rotating shaft via a coupling.

[0008] Preferably, the cam is transmission-connected to the rotating shaft by a key connection.

[0009] Preferably, the rotating shaft is rotatably disposed on the supporting seat via a bearing.

[0010] As described above, the valve grinding device of the utility model has the following beneficial effects: when in use, the cylinder head is placed upside down on the support frame, and then the valve is installed in the corresponding valve hole, so that the end of the valve is against the valve support plate, and the driving source drives the rotating shaft to rotate, and the rotating shaft drives the cam to rotate. As the cam rotates, the protrusion of the cam will lift the valve support plate upward, and the valve support plate will support the valve to move upward. When the valve support plate supports the valve to move upward to the highest point, that is, the protrusion of the cam is separated from the valve support plate, the valve support plate and the valve will fall freely by their own gravity, so that the valve will collide with the valve seat in the cylinder head to achieve grinding. Therefore, when the valve is ground by the valve grinding device of the utility model, multiple valves can be supported together by the valve support plate, and multiple valves can be supported to move upward together each time, and multiple valves can be ground each time, which greatly improves the grinding efficiency, avoids the input of manpower, and reduces the labor cost.

[0033] The utility model provides a gas valve grinding device, such as Figure 1 and Figure 4As shown, the valve grinding device includes a support seat 10 and a driving mechanism 20. Specifically, a valve support plate 11 for supporting the valve 101 is slidably provided on the support seat 10, and the valve support plate 11 can slide in the vertical direction; the driving mechanism 20 includes a driving source, a rotating shaft 21 and a cam 22, wherein the rotating shaft 21 is rotatably set on the support seat 10, the driving source is used to drive the rotating shaft 21 to rotate, the cam 22 is fixedly set on the rotating shaft 21, and the cam 22 is located below the valve support plate 11. Specifically, the cam 22 includes a base circular portion 220 and a protruding portion 221. Based on the rotation of the cam 22, the protruding portion 221 can lift the valve support plate 11 from the starting point to the highest point, and the base circular portion 220 can make the valve support plate 11 located at the highest point freely fall to the starting point.

[0034] When the gas valve grinding device of the utility model is used, Figure 1 As shown, the cylinder head 100 is placed upside down on the support frame 10, and then the air valve is installed in the corresponding air valve hole so that the end of the air valve is against the air valve support plate 11, and the driving source drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the cam 22 to rotate.

[0036] Preferably, Figure 1 As shown, in this embodiment, the driving source includes a motor 23, and the motor 23 is connected to the rotating shaft 21 through a coupling 231. During operation, the rotating shaft 21 is driven to rotate by the rotation of the motor 23. Specifically, in this embodiment, the rotating shaft 21 is rotatably arranged on the support seat 10 through a bearing 210.

[0037] Preferably, in the present embodiment, the cam 22 is transmission-connected to the rotating shaft 21 by means of a key connection, which has a simple structure and is convenient for assembly and disassembly, thereby facilitating the maintenance or replacement of the cam at a later stage.

[0038] Specifically, the valve grinding device of the utility model can also lengthen the number of support seats and corresponding cams according to the number of cylinder heads, so as to achieve the effect of grinding the valves on multiple cylinder heads at the same time.

[0039] In summary, the valve grinding device of the utility model overcomes the problems of unreasonable and inapplicable original tooling design, troublesome installation, difficult operation, and inconvenient use, reduces the time of valve grinding, and greatly improves work efficiency. At the same time, the valve grinding device is simple to operate, so that operators can use the valve grinding device faster and more conveniently, and inexperienced personnel can also understand and use the operation faster, so as to ensure the quality of grinding and quantity, and overcome the problems of slow manual grinding speed, low efficiency, and high labor consumption in the original tooling design; the valve grinding device can be designed to operate continuously, so that the valve grinding process can be faster and more efficient, and labor is saved.
