Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve core processing technology, and in particular to a sandblasting device for processing hydraulic valve cores. Background Technology

[0002] The hydraulic valve core is one of the most critical components of a hydraulic valve, primarily used to control parameters such as the direction, flow rate, and pressure of hydraulic oil. By controlling the fluid's path and flow rate, it directly affects the working efficiency and performance of the hydraulic system. During the manufacturing process, the hydraulic valve core requires sandblasting.

[0003] For example, Chinese utility model patent application number CN218110464U discloses a hydraulic valve core sandblasting device, relating to the field of hydraulic valve processing technology. It includes a sandblasting machine, a base, and a support platform. The base is bolted to the sandblasting machine table, and the support platform is welded to the middle of the upper surface of the base. A turntable is rotatably mounted at the center of the support platform, driven by an external motor. A fixing plate is welded to one side of the upper surface of the base, and a limiting component for limiting the valve core is mounted on the fixing plate. In this utility model, the turntable, along with the corresponding lead screw, adjusting plate, and limiting ring, allows the limiting ring to be mounted on the upper end of the valve core, thus limiting and fixing the valve core. Simultaneously, the external motor drives the turntable to rotate, thereby rotating the valve core. This facilitates uniform sandblasting of the valve core surface and ensures the stability of the valve core during sandblasting.

[0004] When existing hydraulic valve core sandblasting devices are used for sandblasting, the sandblasting machine is exposed to the outside environment, which causes the hydraulic valve core to generate debris during the sandblasting process. This debris is prone to flying everywhere, which not only affects the surrounding environment but also causes injury to workers. In addition, the debris requires manual cleaning afterward, which is time-consuming and labor-intensive, reducing the efficiency of hydraulic valve core processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sandblasting device for machining hydraulic valve cores.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sandblasting device for processing hydraulic valve cores, comprising a processing base, a sandblasting machine installed on one side of the inner wall of the processing base, an adjustment component provided on one side of the processing base, two transparent protective frames provided on the outside of the adjustment component, a collection component provided on the surface of the processing base, a placement rack fixedly connected to the bottom of the inner wall of the processing base, a driving component provided at the bottom of the inner wall of the placement rack, a placement plate provided at the top of the driving component, a hollow strip fixedly connected to the bottom of the inner wall of the processing base, openings on both sides of the inner wall of the hollow strip, a moving component provided on one side of the inner wall of the hollow strip, two cleaning plates I provided at the bottom of the moving component, two moving rods provided on the surface of the moving component, a cleaning plate II fixedly connected to the bottom of the moving rods, and an anti-slip component provided at the top of the placement rack.

[0007] By setting up a drive component, the drive component moves the moving component, which in turn moves the two cleaning plates one and two cleaning plates two, thus cleaning the debris into the collection component. At the same time, with the adjustment component, the two transparent protective frames can be installed on the outside of the sandblasting machine to prevent debris from flying.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes an adjustment frame fixedly connected to one side of the processing base. A bidirectional lead screw is rotatably connected to one side of the inner wall of the adjustment frame. Two moving blocks are threadedly connected to the outer surface of the bidirectional lead screw. A drive rod is fixedly connected to one end of the bidirectional lead screw.

[0010] By setting a drive rod, the threaded rod can be rotated, which in turn allows the two moving blocks to move the two transparent protective frames, thereby installing the two transparent protective frames on the outside of the sandblasting machine and the placement plate.

[0011] As a further description of the above technical solution:

[0012] The collection component includes a placement groove formed on the surface of the processing base, a drawer slidably connected between the two sides of the inner wall of the placement groove, and two discharge ports one and two discharge ports two formed on the top of the inner wall of the placement groove.

[0013] By setting up two discharge ports, one for debris and two discharge ports for waste, the debris can be allowed to fall into the drawer.

[0014] As a further description of the above technical solution:

[0015] The drive assembly includes a mounting box fixedly connected to the bottom of the inner wall of the placement frame. A motor is installed at the bottom of the inner wall of the mounting box, and a bevel gear is sleeved on the outside of the output end of the motor.

[0016] By setting up a motor that can drive the placement plate to rotate, the hydraulic valve core on the placement plate will rotate and work in conjunction with the sandblasting machine to evenly sandblast the hydraulic valve core.

[0017] As a further description of the above technical solution:

[0018] The moving component includes a reciprocating lead screw rotatably connected to one side of the inner wall of the hollow strip. The outer surface of the reciprocating lead screw is threaded with a moving strip. One end of the reciprocating lead screw is fixedly connected to a connecting shaft. One end of the connecting shaft passes through the interior of the mounting box and is fixedly connected to a bevel gear.

[0019] By setting a connecting shaft, when the motor starts, the first bevel gear, which meshes with the second bevel gear, can drive the connecting shaft and the reciprocating screw to rotate synchronously, thereby moving the moving bar. The moving bar can then drive the first and second cleaning plates to move, thus facilitating the cleaning of debris.

[0020] As a further description of the above technical solution:

[0021] The second bevel gear meshes with the first bevel gear.

[0022] As a further description of the above technical solution:

[0023] The anti-slip component includes a threaded rod that extends through the bottom of the inner wall of the placement rack, and a drive wheel is fixedly connected to the top of the threaded rod.

[0024] As a further description of the above technical solution:

[0025] The bottom end of the threaded rod is fixedly connected to a clamping frame, and both sides of the inner wall of the clamping frame are fixedly connected to arc-shaped limiting strips.

[0026] By setting two arc-shaped limit bars, the hydraulic valve core on the placement plate can be limited to prevent it from shifting.

[0027] This utility model has the following beneficial effects:

[0028] 1. Compared with existing technologies, this sandblasting device for processing hydraulic valve cores, through the coordinated use of adjusting components, transparent protective frames, collecting components, driving components, moving components, cleaning plate one, moving rod, and cleaning plate two, can install two transparent protective frames on the outside of the sandblasting machine and the hydraulic valve core to be sandblasted, avoiding the splashing of debris generated during sandblasting, preventing debris from injuring workers, improving the safety of the sandblasting device for processing hydraulic valve cores, and automatically cleaning and collecting debris, saving time and labor, and improving the efficiency of hydraulic valve core processing.

[0029] 2. Compared with the prior art, the sandblasting device for processing hydraulic valve cores rotates the drive wheel, which drives the threaded rod to rotate. This causes the threaded rod to move the clamping frame downwards until the two arc-shaped limiting strips move to the outside of the hydraulic valve core to be processed and fit against the outside of the hydraulic valve core. This limits and fixes the hydraulic valve core, preventing it from moving and ensuring the sandblasting effect of the hydraulic valve core. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1-5 This utility model provides a sandblasting device for processing hydraulic valve cores: It includes a processing base 1, a sandblasting machine 2 mounted on one side of the inner wall of the processing base 1, an adjusting component on one side of the processing base 1, two transparent protective frames 3 on the outside of the adjusting component, a collecting component on the surface of the processing base 1, a placement rack 4 fixedly connected to the bottom of the inner wall of the processing base 1, a driving component on the bottom of the inner wall of the placement rack 4, a placement plate 5 on the top of the driving component, a hollow strip 6 fixedly connected to the bottom of the inner wall of the processing base 1, openings on both sides of the inner wall of the hollow strip 6, a moving component on one side of the inner wall of the hollow strip 6, two cleaning plates 7 at the bottom of the moving component, and two moving rods on the surface of the moving component. 28. The bottom of the moving rod 28 is fixedly connected to the cleaning plate 28. The top of the placement rack 4 is equipped with an anti-slip component. The bottom of the cleaning plate 1 7 and the bottom of the cleaning plate 2 8 are both in contact with the bottom of the inner wall of the processing base 1. The transparent protective frame 3 is used to prevent debris from splashing. The placement tray 5 is used to place the hydraulic valve core. The anti-slip component is used to prevent the hydraulic valve core on the placement tray 5 from moving. The collection component is used to collect the debris that has been cleaned. By setting the driving component, the driving component drives the moving component to move, thereby moving the two cleaning plates 1 7 and the two cleaning plates 2 8, which can clean the debris into the collection component. At the same time, with the adjustment component, the two transparent protective frames 3 can be installed on the outside of the placement rack 4 and the sandblasting machine 2, thereby preventing debris from splashing.

[0039] The adjustment assembly includes an adjustment frame 9 fixedly connected to one side of the processing base 1. A bidirectional lead screw 10 is rotatably connected to one side of the inner wall of the adjustment frame 9. Two moving blocks 11 are threadedly connected to the outer surface of the bidirectional lead screw 10. A drive rod 12 is fixedly connected to one end of the bidirectional lead screw 10. The two moving blocks 11 are threadedly connected to two different threads on the bidirectional lead screw 10. The two moving blocks 11 are both L-shaped and one side is fixedly connected to one side of the two transparent protective frames 3 respectively. One end of the drive rod 12 extends through to one side of the adjustment frame 9. By setting the drive rod 12, the threaded rod 24 can be rotated, so that the two moving blocks 11 can drive the two transparent protective frames 3 to move, thereby installing the two transparent protective frames 3 on the outside of the sandblasting machine 2 and the placement plate 5.

[0040] The collection component includes a placement groove 13 formed on the surface of the processing base 1. A drawer 14 is slidably connected between the two sides of the inner wall of the placement groove 13. Two discharge ports 15 and 2 discharge ports 16 are formed on the top of the inner wall of the placement groove 13. The two discharge ports 15 and 2 discharge ports 16 are symmetrical about the center of the placement groove 13. By setting the two discharge ports 15 and 2 discharge ports 16, the debris can fall into the drawer 14.

[0041] The drive assembly includes a mounting box 17 fixedly connected to the bottom of the inner wall of the placement frame 4. A motor 18 is installed at the bottom of the inner wall of the mounting box 17. A bevel gear 19 is sleeved on the outside of the output end of the motor 18. The output end of the motor 18 extends through to the top of the mounting box 17 and is fixedly connected to the bottom of the placement plate 5. By setting the motor 18, it can drive the placement plate 5 to rotate, thereby causing the hydraulic valve core on the placement plate 5 to rotate and cooperate with the sandblasting machine 2 to uniformly sandblast the hydraulic valve core.

[0042] The moving assembly includes a reciprocating screw 20 rotatably connected to one side of the inner wall of the hollow bar 6. A moving bar 21 is threaded onto the outer surface of the reciprocating screw 20. A connecting shaft 22 is fixedly connected to one end of the reciprocating screw 20. One end of the connecting shaft 22 passes through the interior of the mounting box 17 and is fixedly connected to a bevel gear 23. The bevel gear 23 meshes with a bevel gear 19. Two through-holes pass through both sides of the moving bar 21, and its bottom is slidably connected to the bottom of the inner wall of the through-hole. Two cleaning plates 7 are fixedly connected to the bottom of the moving bar 21, and two moving rods 28 are fixedly connected to the surface of the moving bar 21. By setting the connecting shaft 22, when the motor 18 starts, the bevel gear 19 meshing with the bevel gear 23 can drive the connecting shaft 22 and the reciprocating screw 20 to rotate synchronously, thereby moving the moving bar 21. The moving bar 21 can then drive the cleaning plates 7 and 8 to move, thus facilitating the cleaning of debris.

[0043] The anti-slip component includes a threaded rod 24 that extends through the bottom of the inner wall of the placement frame 4. A drive wheel 25 is fixedly connected to the top of the threaded rod 24, and a clamping frame 26 is fixedly connected to the bottom of the threaded rod 24. Arc-shaped limiting strips 27 are fixedly connected to both sides of the inner wall of the clamping frame 26. By setting two arc-shaped limiting strips 27, the hydraulic valve core on the placement plate 5 can be limited to prevent the hydraulic valve core from deviating.

[0044] Working principle: When the hydraulic valve core needs to be processed, the hydraulic valve core to be sandblasted is first placed on the placement plate 5. Then, the drive wheel 25 is rotated, which drives the threaded rod 24 to rotate, thereby driving the clamping frame 26 to move downward until the opposite side of the two arc-shaped limit strips 27 is in contact with the outside of the hydraulic valve core to be sandblasted. Then, the drive rod 12 is rotated, which drives the bidirectional screw 10 to rotate. At this time, the two moving blocks 11 will move closer to each other as the bidirectional screw 10 rotates, until the opposite side of the two transparent protective frames 3 is in contact, so that the transparent protective frames 3 can be installed on the processing base 1.

[0045] Then, the motor 18 is started, causing the placement plate 5 to rotate. At this time, the sandblasting machine 2 is started, which can perform sandblasting on the hydraulic valve core. Simultaneously, the motor 18 drives the bevel gear 19 to rotate. Then, the bevel gear 23 meshing with the bevel gear 19 rotates, which in turn drives the connecting shaft 22 to rotate. The connecting shaft 22 drives the reciprocating screw 20 to rotate. At this time, the moving bar 21 moves with the shape of the reciprocating screw 20, which in turn drives the cleaning plate 7, the moving rod 28, and the cleaning plate 8 to move. This allows the debris that falls to the bottom of the inner wall of the processing base 1 to be pushed into the drawer 14 for collection through the two discharge ports 15 and 16. At the same time, the two transparent protective frames 3 installed on the processing base 1 can prevent debris from splashing.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
