Description

Technical Field

[0001] The utility model relates to the technical field of valve stem grinding, in particular to a deburring and grinding tooling for valve stems. Background Technique

[0002] The valve stem is an important component in a valve, mainly used for transmission. It is connected to the actuator or handle at the top and directly drives the valve core to move or rotate at the bottom to achieve the opening, closing or regulating function of the valve. During the processing, it is necessary to grind and polish its circumferential surface to improve the processing accuracy of the valve stem and facilitate subsequent assembly.

[0003] Common deburring and grinding toolings for valve stems generally fix the valve stem through a fixture and then grind its surface through a grinding mechanism such as a grinding wheel. However, since the fixture will cause a certain blockage to the surface of the valve stem during clamping, it is necessary to insert the valve stem after single grinding and then grind the blocked position, resulting in a time-consuming and laborious whole grinding process and unable to meet the working requirements of valve stem grinding. For this reason, a deburring and grinding tooling for valve stems is proposed. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a deburring and grinding tooling for valve stems to solve the technical problem that the whole grinding process is time-consuming and laborious because the fixture will cause a certain blockage to the surface of the valve stem during clamping.

[0008] A base, a bracket is installed on the left side of the base, connecting frames are connected to both the left and right sides of the front part of the base, a first motor is installed on the outside of the left connecting frame, and the rotor of the first motor is coaxially connected to a main shaft;

[0009] A first bevel gear is coaxially installed on the left side outside the main shaft. A chute is opened on the right side inside the base, a slider is inserted into the chute, and a supporting plate is connected to the top of the slider. A first lead screw is screwed inside the right side of the base. A main hinge frame is connected to the left side of the top of the supporting plate, and a secondary hinge frame is installed on the left side of the top of the base;

[0010] A grinding sand roller is inserted into the main hinge frame and the secondary hinge frame through a rotating shaft. Second bevel gears are installed on the front parts of the main hinge frame and the secondary hinge frame, and the rear parts of the second bevel gears are coaxially connected to the grinding sand roller;

A handwheel is coaxially installed at the right end of the first lead screw. The width of the supporting plate is the same as that of the base, which improves the stability of the supporting plate when moving left and right.

[0013] Preferably, both the bushing and the third bevel gear are sleeved on the outer side of the main shaft. The ribs are all clamped at the corresponding positions inside the bushing and the third bevel gear, and the second bevel gear meshes with the first bevel gear and the third bevel gear. The added ribs enable the bushing and the third bevel gear to move left and right without being affected, and can drive the rotation of the bushing and the third bevel gear synchronously with the rotation of the main shaft.

[0014] Preferably, side plates are connected to both the front and rear sides of the upper part of the bracket. A flat plate is inserted at the position between the side plates on the upper part of the bracket. Blocks are connected to both the left and right sides of the flat plate.

[0015] Preferably, a cylinder is installed on the right side of the upper surface of the flat plate. The bottom end of the cylinder penetrates through the corresponding position of the flat plate. A pressure roller is installed at the bottom end of the cylinder, which facilitates the limitation of the valve stem.

[0016] Preferably, a transmission block is inserted into the left side inside the bracket, and the bottom of the transmission block is connected to the corresponding position of the upper surface of the flat plate. A second lead screw is inserted into the transmission block. A second motor is installed at the upper left part of the bracket, and the rotor of the second motor is coaxially connected to the left end of the second lead screw. The rotation of the second lead screw can be driven by the second motor, so as to adjust the left and right positions of the transmission block and the flat plate, which facilitates the limitation of valve stems with different diameters by the pressure roller.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present utility model provides a valve stem deburring and grinding tooling, which has the following beneficial effects:

[0019] The deburring and grinding tooling for the valve stem places the valve stem to be ground between the grinding sand rollers, and then drives the rotation of the main shaft through the first motor, so that the rotation of the second bevel gear can be driven through the first bevel gear and the third bevel gear, and the movement of the pressure roller is driven by the cylinder to limit the valve stem, so that the outer circumference of the valve stem can be ground all-round by the rotating grinding sand rollers. This not only avoids the problem of repeated clamping, but also improves the speed and quality of grinding the valve stem. At the same time, the rotation of the first lead screw can be driven by rotating the handwheel, and then the slider and the supporting plate can be driven to move left and right, which facilitates the adjustment of the distance between the two groups of grinding sand rollers. It can not only adjust the depth of contact between the valve stem and the grinding sand rollers during grinding, but also facilitate the grinding of valve stems with different diameters, improving the adaptability of the device.
