Description

Technical Field

[0001] The utility model belongs to the technical field of the design of processing facilities for the gate plate of a protective gate valve, and particularly relates to a fixture for processing the gate plate of a protective gate valve. Background Technique

[0002] The gate plate of a protective gate valve is one of the key components of the gate valve, and it is directly responsible for cutting off or allowing the fluid to flow when the valve is opened and closed. The gate plate usually moves between two sealing surfaces inside the valve body. When the gate plate is fully lifted, the fluid can freely pass through the valve; when the gate plate descends onto the valve seat, it seals the valve and prevents the fluid from flowing.

[0003] When the existing fixture for processing the gate plate of a protective gate valve processes a wedge-shaped gate plate, there is a lack of a design that can fix the wedge-shaped gate plate through the inclined surface to make its surface to be processed vertical. The adaptability of the device to the wedge-shaped gate plate is poor. At the same time, it is difficult to flexibly adjust according to the inclination angle of the gate plate when processing gate plates of different specifications, and the comprehensiveness of the device processing is relatively low. When the device fixes a gate plate with a relatively special shape, the clamping strength is not high enough, and the processing stability is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixture for processing the gate plate of a protective gate valve to solve the problems existing in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A fixture for processing the gate plate of a protective gate valve includes a base device. A base device is arranged at the top of the base device, and a fixing device is arranged on one side of the base device; the base device includes a rotating block, an inclined disk is fixedly arranged on one side of the rotating block, two limiting blocks are symmetrically and fixedly arranged in the middle of the inclined disk, and two limiting frames are respectively and fixedly arranged on the upper and lower surfaces of the inclined disk; the fixing device includes a transition disk, two limiting grooves are symmetrically arranged on one side of the transition disk, a fixing ring is fixedly arranged on the side of the transition disk away from the limiting grooves, a wedge-shaped gate plate is arranged on one side of the fixing ring, two positioning protrusions are symmetrically arranged on both sides of the wedge-shaped gate plate, a valve rod mounting hole is arranged in the middle of the wedge-shaped gate plate, a fixing rod is arranged on the wedge-shaped gate plate, and a cross bar is inserted and connected to the upper and lower ends of the fixing rod.

[0007] Further: The base device includes a processing seat, a motor is installed at the top of the processing seat, a hydraulic cylinder is installed at the bottom of the processing seat, and a limiting shaft is arranged at the output end of the hydraulic cylinder.

[0008] Further: The rotating block is connected to the motor by a flat key, and the motor is connected to the processing seat by bolts.

[0009] Further: The transition disk is inserted and connected to the limiting block, and the positioning protrusion is inserted and connected to the fixing ring.

[0010] Further: The transition disk is wedge-shaped.

[0011] Further: The limiting frame is U-shaped.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] When installing the fixture, first attach the transition disk to the inclined disk. The limiting block on the surface of the inclined disk is inserted into the limiting groove on the back of the transition disk. Since the transition disk is wedge-shaped, compared with directly installing on the inclined disk, the inclination degree of the wedge gate installed on the transition disk changes, and the wedge gate approaches the transition disk. During this process, the left positioning protrusion is inserted into the fixing ring. At this time, the right side of the wedge gate is in a vertical state. By setting the design of using the transition disk to support the right side of the wedge gate to remain vertical, the cutting difficulty of the wedge gate is reduced. At the same time, when the inclination angle of the size of the wedge gate to be processed changes, only need to replace the transition disk with different slopes, which is convenient to adapt to different specifications of wedge gates, improve the comprehensiveness of device processing. After one side of the processing is completed, flipping the wedge gate can process the other side of the wedge gate, which is convenient to improve the processing speed;

[0014] Insert the fixing rod into the valve stem installation hole, then insert the two cross bars into the upper and lower ends of the fixing rod. The two cross bars are respectively clamped into the limiting frame, and then the cross bars are fixed by bolts. At this time, the wedge gate is pressed on the transition disk by the fixing rod, completing the limiting clamping work of the wedge gate. Through the design of fixing the wedge gate by inserting the fixing rod into the valve stem installation hole, using the valve stem installation hole originally used for installing the valve stem, the wedge gate is fixed more stably, improving the clamping strength, being more suitable for the processing environment of the wedge gate, and the device has stronger practicability.

[0025] See also Figures 1 - 5 The protective gate valve gate processing fixture comprises a base device 1, a base device 2 is arranged on the top of the base device 1, and a fixing device 3 is arranged on one side of the base device 2.

[0026] In this embodiment: the base device 1 includes a processing seat 101, a motor 102 is installed on the top of the processing seat 101, a hydraulic cylinder 103 is installed at the bottom of the processing seat 101, a limit shaft 104 is set at the output end of the hydraulic cylinder 103, the rotating block 201 is connected with the motor 102 with a flat key, the motor 102 is connected with the processing seat 101 with bolts, the processing seat 101 supports the hydraulic cylinder 103 to extend, and drives the limit shaft 104 to support the positioning protrusion 305 on the right side of the wedge gate 304, further improving the clamping reliability, and finally the processing seat 101 supports the motor 102 to drive the rotating block 201 to rotate, driving the wedge gate 304 to rotate, so that the tool 4 cuts it;

[0027] In this embodiment: the base device 2 includes a rotating block 201, a swash plate 202 is fixedly provided on one side of the rotating block 201, two limit blocks 203 are symmetrically fixedly provided in the middle of the swash plate 202, and two limit frames 204 are fixedly provided on the upper and lower sides of the swash plate 202, respectively. The limit frames 204 are U-shaped, and the transition plate 301 is attached to the swash plate 202, and the limit blocks 203 on the surface of the swash plate 202 are inserted into the limit grooves 302 on the back of the transition plate 301;

[0028] In this embodiment: The fixing device 3 includes a transition disk 301. On one side of the transition disk 301, two limiting grooves 302 are symmetrically arranged. On the side of the transition disk 301 away from the limiting grooves 302, a fixing ring 303 is fixedly arranged. On one side of the fixing ring 303, a wedge-shaped gate plate 304 is arranged. On both sides of the wedge-shaped gate plate 304, two positioning protrusions 305 are symmetrically arranged. In the middle of the wedge-shaped gate plate 304, a valve stem mounting hole 306 is arranged. On the wedge-shaped gate plate 304, a fixing rod 307 is arranged. The upper and lower ends of the fixing rod 307 are inserted and connected with a cross bar 308. The transition disk 301 is inserted and connected with the limiting block 203, and the positioning protrusion 305 is inserted and connected with the fixing ring 303. The transition disk 301 is wedge-shaped. When machining the wedge-shaped gate plate 304, since the two side surfaces of the wedge-shaped gate plate 304 are not parallel, an inclined fixture is needed to fix the left side of the wedge-shaped gate plate 304 to ensure that the right side surface to be machined can remain vertical, which is convenient for the cutter 4 to perform cutting. When the fixture is installed, since the transition disk 301 is wedge-shaped, compared with directly installing on the inclined disk 202, the inclination degree of the wedge-shaped gate plate 304 installed on the transition disk 301 changes. The wedge-shaped gate plate 304 is close to the transition disk 301. During this process, the left positioning protrusion 305 is inserted into the fixing ring 303. At this time, the right side surface of the wedge-shaped gate plate 304 is vertical. Insert the fixing rod 307 into the valve stem mounting hole 306, and then insert the two cross bars 308 into the upper and lower ends of the fixing rod 307. The two cross bars 308 are respectively clamped into the limiting frame 204, and then the cross bars 308 are fixed by bolts. At this time, the wedge-shaped gate plate 304 is pressed on the transition disk 301 by the fixing rod 307, and the limiting clamping work of the wedge-shaped gate plate 304 is completed. By setting the design that the transition disk 301 supports the right side of the wedge-shaped gate plate 304 to remain vertical, the cutting difficulty of the wedge-shaped gate plate 304 is reduced. At the same time, when the size of the wedge-shaped gate plate 304 to be machined changes in the inclination angle, only the transition disk 301 with different slopes needs to be replaced, which is convenient for adapting to wedge-shaped gate plates 304 of different specifications and improving the comprehensiveness of device processing. After one side of the processing is completed, the wedge-shaped gate plate 304 is flipped to process the other side of the wedge-shaped gate plate 304, which is convenient for improving the processing speed. By the design of inserting the fixing rod 307 into the valve stem mounting hole 306 to fix the wedge-shaped gate plate 304, using the valve stem mounting hole 306 originally used for installing the valve stem, the wedge-shaped gate plate 304 is fixed more stably, the clamping strength is improved, and it is more suitable for the processing environment of the wedge-shaped gate plate 304, and the device has stronger practicability.

[0029] Working principle: When processing the wedge gate 304, since the two sides of the wedge gate 304 are not parallel, an inclined fixture is required to fix the left side of the wedge gate 304 to ensure that the right side to be processed can remain vertical, which is convenient for the tool 4 to cut. When installing the fixture, first fit the transition plate 301 to the inclined plate 202, and insert the limit block 203 on the surface of the inclined plate 202 into the limit groove 302 on the back of the transition plate 301. Since the transition plate 301 is wedge-shaped, it is easier to install the wedge on the transition plate 301 than directly on the inclined plate 202. The inclination of the wedge gate 304 changes, and the wedge gate 304 is close to the transition plate 301. During this process, the left positioning protrusion 305 is inserted into the fixing ring 303. At this time, the right side of the wedge gate 304 is in a vertical state. The fixing rod 307 is inserted into the valve stem mounting hole 306, and then the two cross bars 308 are inserted into the upper and lower ends of the fixing rod 307. The two cross bars 308 are respectively inserted into the limit frame 204, and then the cross bars 308 are fixed by bolts. At this time, the wedge gate 304 is pressed on the transition plate 301 by the fixing rod 307, completing the limit clamping of the wedge gate 304 The processing base 101 supports the hydraulic cylinder 103 to extend, driving the limit shaft 104 to support the positioning protrusion 305 on the right side of the wedge gate 304, further improving the clamping reliability. Finally, the processing base 101 supports the motor 102 to drive the rotating block 201 to rotate, driving the wedge gate 304 to rotate, so that the tool 4 can cut it. By setting the transition plate 301 to support the right side of the wedge gate 304 to keep it vertical, the cutting difficulty of the wedge gate 304 is reduced. At the same time, when the size of the wedge gate 304 to be processed changes, it only needs to be replaced. Transition plates 301 with different inclinations can be used to adapt to wedge gate plates 304 of different specifications, thereby improving the comprehensiveness of the device processing. After one side is processed, the wedge gate plate 304 can be flipped over to process the other side of the wedge gate plate 304, thereby improving the processing speed. The wedge gate plate 304 is fixed by inserting the fixing rod 307 into the valve stem mounting hole 306, and the valve stem mounting hole 306 originally used to install the valve stem is utilized. This makes the wedge gate plate 304 more stably fixed, improves the clamping strength, is more adapted to the processing environment of the wedge gate plate 304, and makes the device more practical.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
