Description

Technical Field

[0001] This utility model belongs to the field of distribution valve assembly technology, specifically relating to a distribution valve clamping device. Background Technology

[0002] As a crucial component of the EMU braking system, the distributor valve is assembled on a maintenance workbench. Due to its unique structure, the lower end face of the distributor valve must be placed on the workbench during assembly. The valve's movement and rotation during assembly cause continuous friction and impact between the lower end face and the workbench surface. Since the lower end face of the distributor valve is the mounting mating surface, its smoothness and flatness must be ensured during installation on the EMU.

[0003] Chinese Patent CN215617604U discloses a valve clamping device, comprising: a base; a turntable mounted on the base and rotatable around its center; a fixing device mounted on the turntable for fixing the valve; and a turntable positioning device mounted on the turntable for fixing the turntable. The fixing device includes clamps disposed opposite to each other on both sides of the turntable. Each clamp is L-shaped, with its vertical side connected to and perpendicular to the turntable, and its horizontal side positioned at the top of the vertical side and extending inwards towards the turntable. One end of each clamp has a baffle between its vertical and horizontal sides, and the other end has a detachable locking device. The locking device is a locking pin inserted into the horizontal side of the clamp.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: because the spacing between the two clamps in the aforementioned technologies is fixed, the device can only be used for clamping distribution valves of the same width, resulting in poor versatility. Utility Model Content

[0005] The purpose of this invention is to provide a valve clamping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distribution valve clamping device, comprising a base, a turntable, and a clamping assembly, wherein a circular groove is provided on the top of the base, the turntable is rotatably installed in the circular groove, the clamping assembly is disposed on the turntable, and a plurality of annularly distributed positioning grooves are provided on the outer circumference of the turntable, and a positioning assembly is provided on one side of the base located in the circular groove. The clamping assembly includes two C-shaped clamps symmetrically arranged on the turntable. The top of the turntable has a sliding groove, and the bottom of the C-shaped clamps has a slider. The slider slides in the sliding groove, and a bidirectional screw is rotatably installed inside the sliding groove. The slider is sleeved on the bidirectional screw and threadedly connected to the bidirectional screw.

[0007] In a preferred embodiment, a handle is fixedly connected to one end of the bidirectional screw.

[0008] In a preferred embodiment, the top of the C-shaped clip is threaded with a clamping rod, and the bottom of the clamping rod is fixedly connected with a clamping plate.

[0009] In a preferred embodiment, the positioning component includes a positioning block embedded in one side of the circular groove and a spring abutting against one end of the positioning block.

[0010] In a preferred embodiment, the positioning block is adapted to the positioning groove.

[0011] In a preferred embodiment, a push block is fixedly connected to the top of the positioning block, and the push block slides within a through hole, which is formed on the surface of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This distribution valve clamping device, through the setting of the clamping components, allows for clamping and assembling of the distribution valve by first rotating the handle to control the rotation of the bidirectional screw, which in turn drives two sliders to slide relative to or opposite to each other along the slide groove. The sliders then drive the C-type clamps to move, adjusting the distance between the two C-type clamps to match the width of the distribution valve. This facilitates clamping of distribution valves of different specifications and improves versatility. This valve clamping device, through the setting of positioning grooves and positioning components, allows the push block to be pushed to pull the positioning block out of the current positioning groove when the clamped valve needs to be rotated. Since the turntable is not positioned, it can be manually rotated at this time, which in turn drives the valve to rotate. After the valve rotates to a certain angle, the push block can be released to allow the spring to push the positioning block into the corresponding positioning groove, thus positioning the turntable and facilitating the adjustment of the valve angle.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1-3 This utility model provides a clamping device for a distribution valve, including a base 1, a turntable 2, and a clamping assembly 3. A circular groove 11 is formed on the top of the base 1, and the turntable 2 is rotatably mounted within the groove 11. The clamping assembly 3 is mounted on the turntable 2 and includes two C-shaped clips 31 symmetrically arranged on the turntable 2. A sliding groove 32 is formed on the top of the turntable 2, and a slider 33 is provided at the bottom of each C-shaped clip 31. The slider 33 slides within the sliding groove 32, and a bidirectional screw 34 is rotatably mounted inside the sliding groove 32. The slider 33 is sleeved on the bidirectional screw 34. The device is threadedly connected to the bidirectional screw 34, one end of which is fixedly connected to a handle 35. With the clamping assembly 3, when clamping and assembling the distribution valve, the handle 35 can be rotated to control the bidirectional screw 34 to rotate, so that the bidirectional screw 34 drives the two sliders 33 to slide relative to or opposite to each other along the slide groove 32. The sliders 33 drive the C-type clamps 31 to move, and the distance between the two C-type clamps 31 can be adjusted so that the distance between the two C-type clamps 31 matches the width of the distribution valve, thereby facilitating the clamping of distribution valves of different specifications and improving versatility.

[0018] Furthermore, the top of the C-type clamp 31 is threaded with a clamping rod 36, and the bottom of the clamping rod 36 is fixedly connected with a clamping plate 37. With the clamping rod 36 and the clamping plate 37, when clamping the distribution valve, the clamping rod 36 can be rotated to drive the clamping plate 37 to descend, so that the clamping plate 37 presses against the distribution valve for fixation.

[0019] Multiple annularly distributed positioning grooves 21 are formed on the outer circumference of the turntable 2. The number of positioning grooves 21 is a multiple of four. A positioning component 12 is provided on one side of the circular groove 11 on the base 1. The positioning component 12 includes a positioning block 121 embedded on one side of the circular groove 11 and a spring 122 abutting against one end of the positioning block 121. The positioning block 121 is adapted to the positioning groove 21. A push block 123 is fixedly connected to the top of the positioning block 121. The push block 123 slides in the through hole 124. The through hole 124 is formed on the surface of the base 1. The positioning slot 21 and positioning component 12 are configured so that when the clamped distribution valve needs to be rotated, the push block 123 can be pushed to pull the positioning block 121 out of the current positioning slot 21. Since the turntable 2 is not positioned, the turntable 2 can be manually rotated at this time, and the distribution valve can be rotated through the turntable 2. After the distribution valve rotates to a certain angle, the push block 123 can be released so that the spring 122 pushes the positioning block 121 to insert into the current corresponding positioning slot 21, thereby positioning the turntable 2, which facilitates the adjustment of the angle of the distribution valve.

[0020] The working principle and usage process of this utility model are as follows: First, when clamping and assembling the distribution valve, the handle 35 can be rotated to control the rotation of the bidirectional screw 34, causing the bidirectional screw 34 to drive the two sliders 33 to slide relative to or opposite to each other along the slide groove 32. The sliders 33 drive the C-type clamps 31 to move, adjusting the distance between the two C-type clamps 31 to match the width of the distribution valve. Then, the two sides of the distribution valve can be placed into the C-type clamps 31, and the clamping rod 36 is rotated to drive the clamping plate 37 to descend, so that the clamping... Plate 37 is fixed against the distribution valve. When it is necessary to rotate the clamped distribution valve, push block 123 can be pushed to drive positioning block 121 out of the current positioning slot 21. Since the turntable 2 is not positioned, the turntable 2 can be manually rotated at this time. The turntable 2 drives the distribution valve to rotate. When the distribution valve rotates to a certain angle, push block 123 can be released so that spring 122 pushes positioning block 121 into the current corresponding positioning slot 21, thereby positioning the turntable 2 and facilitating the adjustment of the angle of the distribution valve.
