Description

Technical Field

[0001] The invention relates to the technical field of valve processing, and in particular to a hydraulic valve body processing fixture. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure regulating valve and is usually used in combination with an electromagnetic pressure regulating valve. It can be used to remotely control the on / off of oil, gas, and water pipeline systems in hydropower stations. As a shell component, the hydraulic valve body is subjected to great pressure during use, so it is manufactured in an integrated manner. After the valve body is manufactured, it is also necessary to perform operations such as grinding, painting, and drilling. Therefore, a hydraulic valve body processing fixture is required.

[0003] However, the existing hydraulic valve body processing fixture still has the following defects during use:

[0004] 1. Traditional processing fixtures are all clamped inward from the outer walls on both sides of the hydraulic valve body. However, after clamping, the surfaces on both sides of the hydraulic valve body will be blocked, and there will be places that cannot be polished and painted, which reduces the effect of subsequent processing. Some internal extrusion processing fixtures can only extrude and limit hydraulic valve bodies with the same inner diameter, and cannot meet the needs of hydraulic valve bodies with different inner diameters on both sides. The practicality needs to be improved.

[0005] 2. After the existing processing fixture completes the clamping and fixing, when the hydraulic valve body needs to be flipped and adjusted, the hydraulic valve body needs to be removed and then re-fixed, which is time-consuming and labor-intensive, reducing the processing efficiency. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that when the hydraulic valve body is extruded and limited on the outside, there will be places that cannot be polished and painted, which reduces the effect of subsequent processing, and some internal extrusion processing fixtures can only extrude and limit hydraulic valve bodies with the same inner diameter, and cannot meet the needs of hydraulic valve bodies with different inner diameters on two opposite sides, and the practicality needs to be improved. In addition, when the hydraulic valve body needs to be flipped and adjusted, the hydraulic valve body needs to be removed and re-fixed, which is time-consuming and labor-intensive, reducing the processing efficiency. The present invention provides a hydraulic valve body processing fixture.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A hydraulic valve body processing fixture comprises a base, wherein limit grooves are symmetrically provided on the left and right sides of the top of the base, wherein the inside of the limit grooves are both limitedly slidably connected with sliders, and a mounting block is fixedly installed on the top of the slider, and a clamping adjustment component is arranged inside the base, and the clamping adjustment component is used to drive the mounting blocks on both sides to move toward or away from each other, and an extrusion limit component is arranged on the adjacent side of the mounting blocks on the left and right sides, and a hydraulic valve body is limitedly placed between the extrusion limit components on the left and right sides, and the extrusion limit component is used to perform outward extrusion limit from the inner side of the left and right sides of the hydraulic valve body.

[0009] Furthermore, the clamping adjustment assembly includes a rotating shaft, and the middle part of the base is rotatably connected to the rotating shaft, the rotating shaft is distributed left and right inside the base, and threaded grooves are provided on the periphery of the left and right sides of the rotating shaft, and a gear is fixedly installed on the periphery of the middle part of the rotating shaft, and a worm is rotatably connected to the lower part of the gear inside the base, and the worm is distributed front and back inside the base, and the worm is meshed with the gear. Therefore, when the worm rotates, it can drive the gear to rotate stably, and the front end of the worm extends forward to the front side of the base, and the front end of the worm is fixedly installed with a handle to facilitate driving the worm to rotate.

[0010] Furthermore, the rotating shaft passes through the center of the sliders on the left and right sides, and the sliders are threadedly connected to the thread grooves on the left and right sides of the outer periphery of the rotating shaft, so that the sliders can be driven to move during the rotation of the rotating shaft.

[0011] Furthermore, the threads of the thread grooves on the left and right sides of the outer periphery of the rotating shaft are opposite, so that the rotation of the rotating shaft drives the sliding blocks on both sides to move towards or away from each other.

[0012] Furthermore, the extrusion limiting assembly includes a cylindrical cover, and the adjacent sides of the left and right mounting blocks are slidably connected with the cylindrical covers, and the cylindrical cover is fixedly connected with a spring between one end inside the mounting block and the inner wall of the mounting block, and the adjacent sides of the left and right cylindrical covers are evenly provided with sliding grooves, and the interiors of the sliding grooves are both limitedly slidably connected with extrusion columns, and a central axis is fixedly installed at the center of the interior of the mounting block, and a transmission rod is transmission-connected between the central axis and the extrusion column, and an elastic extrusion assembly is arranged inside the extrusion column.

[0013] Furthermore, one end of the transmission rod is hinged to the central axis, and the other side is hinged to the extrusion columns after being expanded outward. Therefore, when the cylindrical cover moves inward relative to the mounting block, the transmission rod can push the extrusion columns to expand outward through the action of the transmission rod. Conversely, when the cylindrical cover moves outward relative to the mounting block, the transmission rod can pull the extrusion columns inward to retract.

[0014] Furthermore, the elastic extrusion component includes a circular groove, a circular groove is opened inside the extrusion column, the opening of the circular groove faces the outside of the extrusion column, the inside of the circular groove is slidably connected with a mounting column, the mounting column is located inside the extrusion column and is fixedly connected with spring 2 between one end and the inner wall of the extrusion column, and a ball is connected to the side of the mounting column away from spring 2 for limiting rolling.

[0015] Furthermore, the elastic extrusion component is located on the side where the extrusion column extends to the outside of the cylindrical cover, so that during the clamping process, the elastic extrusion component can be located on the inner side of the inner walls on both sides of the hydraulic valve body to elastically extrude and support the hydraulic valve body.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention, through the cooperation of the clamping adjustment component and the extrusion limit component, can drive the extrusion column to extrude and limit the hydraulic valve body from the inner sides of both sides of the hydraulic valve body, without blocking the surface of the hydraulic valve body, ensuring the normal polishing and painting, improving the processing effect, and can also stably clamp and fix the hydraulic valve bodies with different inner diameters on both sides, improving the practicality of the clamp.

[0018] 2. The present invention, through the design of the elastic extrusion component in the extrusion limit component, can elastically extrusion limit the inner wall of the hydraulic valve body, and can stably flip and adjust without removing the hydraulic valve body, and the operation is convenient and quick, thereby improving the processing efficiency.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] A hydraulic valve body processing fixture according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 3 As shown, a hydraulic valve body processing fixture includes a base 1, and limit grooves 2 are symmetrically provided on the left and right sides of the top of the base 1. The inside of the limit grooves 2 are both limited and slidably connected with sliders 3, and the top of the slider 3 is fixedly installed with a mounting block 4. A clamping adjustment component 5 is arranged inside the base 1, and the clamping adjustment component 5 is used to drive the mounting blocks 4 on both sides to move toward or away from each other. An extrusion limit component 6 is arranged on the adjacent side of the mounting blocks 4 on the left and right sides, and a hydraulic valve body 7 is placed between the extrusion limit components 6 on the left and right sides for limiting. The extrusion limit component 6 is used to perform outward extrusion limiting from the inner side of the left and right sides of the hydraulic valve body 7.

[0030] like Figure 2-Figure 3 As shown, the clamping adjustment component 5 includes a rotating shaft 51, and the central limit rotation connection inside the base 1 is connected with the rotating shaft 51, the rotating shaft 51 is distributed left and right inside the base 1, and the periphery of the left and right sides of the rotating shaft 51 is provided with a threaded groove 52, the rotating shaft 51 passes through the center of the sliders 3 on the left and right sides, and the sliders 3 are threadedly connected to the threaded grooves 52 on the left and right sides of the periphery of the rotating shaft 51, so that during the rotation of the rotating shaft 51, the sliders 3 can be driven to move, and the threads of the threaded grooves 52 on the left and right sides of the periphery of the rotating shaft 51 are opposite, so that the rotation of the rotating shaft 51 drives the movement of the sliders 3 on both sides to move toward or away from each other.

[0031] A gear 53 is fixedly installed on the outer periphery of the middle part of the rotating shaft 51, and a worm 54 is connected to the lower limit rotation of the gear 53 inside the base 1. The worm 54 is distributed front and back inside the base 1, and the worm 54 is meshed with the gear 53. Therefore, when the worm 54 rotates, it can drive the gear 53 to rotate stably. The front end of the worm 54 extends forward to the front side of the base 1, and a turning handle 55 is fixedly installed on the front end of the worm 54 to facilitate driving the worm 54 to rotate.

[0032] like Figure 4-Figure 7 As shown, the extrusion limiting assembly 6 includes a cylindrical cover 61, and the adjacent sides of the left and right mounting blocks 4 are slidably connected with the cylindrical cover 61, and the cylindrical cover 61 is fixedly connected with a spring 62 between one end of the cylindrical cover 61 located inside the mounting block 4 and the inner wall of the mounting block 4, and the adjacent sides of the left and right cylindrical covers 61 are evenly provided with sliding grooves 63, and the interior of the sliding grooves 63 is limited and slidably connected with extrusion columns 64, and a central axis 65 is fixedly installed at the center of the interior of the mounting block 4, and a transmission rod 66 is transmission-connected between the central axis 65 and the extrusion column 64, and one end of the transmission rod 66 is hinged to the central axis 65, and the other side is hinged to the extrusion column 64 after being expanded outwardly. Therefore, when the cylindrical cover 61 moves inward relative to the mounting block 4, the transmission rod 66 can push the extrusion column 64 to expand outward through the action of the transmission rod 66. Conversely, when the cylindrical cover 61 moves outward relative to the mounting block 4, the transmission rod 66 can pull the extrusion column 64 inward to retract.

[0033] Furthermore, if Figure 8 As shown, an elastic extrusion component 67 is provided inside the extrusion column 64, and the elastic extrusion component 67 includes a circular groove 671. A circular groove 671 is opened inside the extrusion column 64, and the opening of the circular groove 671 faces the outside of the extrusion column 64. A mounting column 672 is slidably connected inside the circular groove 671. The mounting column 672 is located between one end inside the extrusion column 64 and the inner wall of the extrusion column 64 and is fixedly connected with a spring 2 673. A side of the mounting column 672 away from the spring 2 673 is limitedly connected with a rolling ball 674.

[0034] The elastic extrusion component 67 is located on the side where the extrusion column 64 extends to the outside of the cylindrical cover 61, so that during the clamping process, the elastic extrusion component 67 can be located on the inner side of the inner walls on both sides of the hydraulic valve body 7 to elastically extrude and support the hydraulic valve body 7.

[0035] The working principle of the present invention is:

[0036] When the hydraulic valve body 7 needs to be clamped and fixed, the hydraulic valve body 7 is first placed in the center between the left and right mounting blocks 4, and then the worm 54 is driven to rotate by the turning handle 55. During the rotation of the worm 54, the mutual engagement between the worm 54 and the gear 53 can drive the gear 53 to rotate stably, thereby driving the rotating shaft 51 to rotate.

[0037] During the rotation of the rotating shaft 51, the threaded connection between the outer thread grooves 52 on both sides of the rotating shaft 51 and the slider 3, as well as the opposite thread design of the outer thread grooves 52 on both sides of the rotating shaft 51, can drive the slider 3 to move toward each other in the limiting groove 2, and then drive the mounting block 4 to move toward each other.

[0038] When the mounting block 4 carries the extrusion limit assembly 6 and moves toward each other, it can squeeze the hydraulic valve body 7 placed in the center, so that the inner wall of the adjacent side of the cylindrical cover 61 on both sides contacts the left and right end faces of the hydraulic valve body 7, and under the action of the reaction force, the cylindrical cover 61 will compress the spring 62 and move inward relative to the mounting block 4. In the process of the inward movement of the cylindrical cover 61, the extrusion column 64 can be pushed to move outward through the action of the transmission rod 66.

[0039] During the process of the extrusion column 64 moving outward, the ball 674 on the internal mounting column 672 of the extrusion column 64 will contact the inner wall of the hydraulic valve body 7, and in the process of continued extrusion, the extrusion column 64 will compress the spring 2 673 into the inside of the circular groove 671 to make the outer edge of the extrusion column 64 squeeze and contact with the hydraulic valve body 7, thereby completing the extrusion limit fixation of the hydraulic valve body 7 from the inside.

[0040] By means of the design of respectively controlling the extrusion limit assemblies 6 on both sides, when the inner diameters of the hydraulic valve body 7 on the two sides are different, the cylindrical covers 61 on both sides will contract to different degrees, so that the extrusion columns 64 on both sides will expand to different extents until they contact the inner wall of the hydraulic valve body 7 to complete the extrusion limit, thereby completing the extrusion fixation of the hydraulic valve body 7 with different inner diameters on the two sides.

[0041] When the hydraulic valve body 7 needs to be flipped and adjusted, the squeezing column 64 is slightly contracted by slightly reversing the turning handle 55, and the mounting column 672 is ejected outward by the action of the spring 2 673, so that the mounting column 672 cooperates with the spring 2 673 to elastically squeeze and limit the inner wall of the hydraulic valve body 7, and the ball 674 on the outside of the mounting column 672 can contact the inner wall of the hydraulic valve body 7, which is beneficial to the rotation of the hydraulic valve body 7, thereby completing the flipping adjustment of the hydraulic valve body 7. After the flipping adjustment is completed, the hydraulic valve body 7 can be squeezed and fixed again by turning the turning handle 55 forward again.

[0042] After the processing is completed, the handle 55 is continuously reversed, the extrusion column 64 will shrink inward, and then the mounting block 4 will drive the cylindrical cover 61 to expand to both sides, thereby removing the hydraulic valve body 7.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
