Description

Technical Field

[0001] This utility model relates to the field of valve body manufacturing technology, and in particular to a multi-angle grinding device for valve body manufacturing. Background Technology

[0002] The valve body is a major component of a valve. Different mechanical manufacturing methods are used depending on the pressure rating. Valve bodies for medium and low pressure specifications are usually produced by casting, while those for medium and high pressure specifications are produced by forging. Together with the valve core and valve seat sealing ring, they form a seal that can effectively withstand the pressure of the medium. During the valve body production process, the valve body needs to be polished.

[0003] A search revealed a Chinese patent (application number "202021710635.8") disclosing "a multi-angle grinding device for valve body production." This grinding device includes a frame with two symmetrically arranged snap-fit ​​plates bolted to its side wall. Each snap-fit ​​plate has a movable snap-fit ​​mechanism for snapping and fixing the valve body. The frame also has two symmetrically arranged transmission grooves, with a support block slidably connected within each groove. A fixing plate is fixedly connected to the upper surface of each support block, and the fixing plate has a grinding wheel mechanism for grinding the valve body. However, this grinding device cannot perform all-around grinding of the valve body's outer wall, nor can it adjust the angle of the grinding blocks according to the valve body's shape, making it unable to completely grind irregularly shaped surfaces, resulting in low practicality. Utility Model Content

[0004] This utility model provides a multi-angle grinding device for valve body production, which solves the problems of the grinding device proposed in the prior art, which cannot perform all-round grinding of the outer wall of the valve body, cannot adjust the angle of the grinding block according to the shape of the valve body, cannot completely grind irregular surfaces, and has low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-angle grinding device for valve body production includes an operating table with a rotating mechanism inside. The rotating mechanism includes a rotary motor, a drive shaft connected to the top of the rotary motor's output shaft via a coupling, and a rotary table fixed to the top of the drive shaft. A limiting assembly is provided on the top of the rotary table. The limiting assembly includes a mounting ring bolted to the outer wall of the top of the rotary table, a limiting plate with three channels, an adjusting plate with three arc-shaped slides, a connecting shaft fixed to the bottom outer wall of the adjusting plate, a worm gear connected to the outer wall of the connecting shaft via a pin, and a worm engaging with the worm gear to form a transmission connection. Three clamping assemblies are provided inside the mounting ring. Each clamping assembly includes a slider slidably fitted within a channel, a clamping block bolted to the top outer wall of the slider, and an adjusting rod slidably fitted within a slide. An adjustment mechanism is provided on one side of the operating table. The adjustment mechanism includes a mounting base bolted to one outer wall of the operating table, a linear slide bolted to the upper outer wall of one side of the mounting base, and a connecting plate bolted to the outer wall of the linear slide. A transmission assembly is provided on one side of the connecting plate. The transmission assembly includes a mounting shaft passing through and connected to the outer wall of the connecting plate via a bearing, a fixing plate fixed to the outer wall of one end of the mounting shaft, a top plate bolted to the top outer wall of the fixing plate, a transmission motor bolted to the top outer wall of the top plate, and a mounting cylinder passing through and connected to the outer wall of the top plate via a bearing. A lifting assembly is provided on the top plate. The lifting assembly includes a lifting cylinder bolted to the top outer wall of the top plate, a lifting plate bolted to the top of the piston rod of the lifting cylinder, a lifting shaft passing through and connected to the outer wall of the lifting plate via a bearing, and a grinding wheel.

[0007] Preferably, a mounting plate is fixed on the upper inner wall of the operating table, and the rotary motor is bolted to the bottom outer wall of the mounting plate, with the rotary table abutting against the top outer wall of the operating table.

[0008] Preferably, the limiting plate is bolted to the upper inner wall of the mounting ring, and the mounting ring has three openings that match the positions of the three channels. The adjusting plate is connected to the middle inner wall of the mounting ring via a bearing. Two fixed cylinders are fixed inside the mounting ring, and the two ends of the worm gear pass through and are connected to the two fixed cylinders via bearings.

[0009] Preferably, the clamping block is slidably mounted on the top outer wall of the limiting plate, the adjusting rod is fixed on the bottom outer wall of the slider, and a limiting ring is screwed to the lower part of the adjusting rod.

[0010] With the above scheme, by rotating the worm gear, the worm gear drives the worm wheel, connecting shaft and adjusting plate to rotate. The adjusting plate causes the three adjusting rods to move along the three slides respectively, thereby realizing the slider to move along the channel. The clamping block contacts the inner or outer wall of the valve body, thereby clamping the valve body. The output shaft of the rotary motor drives the transmission shaft, rotary table and valve body to rotate.

[0011] Preferably, a fastening bolt is screwed onto one side of the outer wall of the connecting plate, and the fastening bolt forms a fastening fit with the mounting shaft. Two triangular plates are fixed on the bottom outer wall of the top plate, and the two triangular plates are respectively connected to one side of the outer wall of the fixing plate by bolts. The lower part of the output shaft of the transmission motor is connected to a pulley by a pin, and the lower outer wall of the mounting cylinder is connected to a driven pulley by a pin, and the pulley forms a transmission fit with the driven pulley by a belt.

[0012] Preferably, a limiting rod is fixed on the outer wall of the top plate, and the lifting plate is slidably installed on the outer wall of the limiting rod. The lifting shaft is located at the lower part of the lifting plate and has a regular hexagonal structure. The lifting shaft is slidably sleeved in the mounting cylinder. A connecting piece is fixed at the bottom end of the lifting shaft, and a grinding wheel is sleeved on the outer wall of the connecting piece. A nut is screwed onto the lower outer wall of the connecting piece, and the nut abuts against the bottom outer wall of the grinding wheel.

[0013] The above scheme involves moving the connecting plate and the fixed plate via a linear slide, followed by the piston rod of the lifting cylinder driving the lifting plate and the connecting shaft to rise, thereby adjusting the position of the grinding wheel so that it contacts the outer or inner wall of the valve body. The output shaft of the drive motor drives the pulley to rotate, which in turn drives the driven pulley, the mounting cylinder, the lifting shaft, and the grinding wheel to rotate. Rotating the fixed plate changes the angle between the lifting shaft and the operating table. The mounting shaft is then fixed with fastening bolts, allowing the angle of the lifting shaft to be adjusted according to the irregular shape of the valve body's outer wall.

[0014] The beneficial effects of this utility model are as follows:

[0015] The linear slide moves the connecting plate and the fixed plate, then the piston rod of the lifting cylinder moves the lifting plate and the connecting shaft upward, thereby adjusting the position of the grinding wheel so that the grinding wheel contacts the outer or inner wall of the valve body. The output shaft of the drive motor drives the pulley to rotate, which in turn drives the driven pulley, the mounting cylinder, the lifting shaft, and the grinding wheel to rotate. Rotating the fixed plate changes the angle between the lifting shaft and the operating table. The mounting shaft is fixed with fastening bolts, so the angle of the lifting shaft can be adjusted according to the irregular shape of the valve body's outer wall. The angle and height of the grinding wheel can be adjusted according to the irregular shape of the valve body, achieving all-round grinding of the outer and inner walls of the valve body, thus improving practicality.
