Description

Technical Field

[0001] This utility model relates to the technical field of high-precision grinding devices for throttle valves, and in particular to a high-precision grinding device for throttle valves. Background Technology

[0002] A throttle valve is a valve that controls fluid flow by changing the throttling cross-section or throttling length. A throttle valve and a check valve connected in parallel can be combined to form a check throttle valve. Throttling valves and check throttle valves are simple flow control valves. In fixed displacement pump hydraulic systems, throttle valves and relief valves work together. High-precision grinding equipment is often required during the machining of throttle valves.

[0003] However, during the high-precision grinding process of most existing throttle valves, debris will fly out, which will not only contaminate the workbench, but also pose a threat to the health of the workers. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a high-precision grinding device for throttle valves, which can solve the technical problem that most existing high-precision grinding devices for throttle valves will have debris flying during the processing and grinding process, which not only contaminates the workbench, but also poses a threat to the health of the workers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-precision grinding device for a throttle valve, comprising a worktable, a pair of baffles fixedly connected to the lower end of the worktable, a first motor provided on one side of the baffle, the output end of the first motor passing through the baffle and fixedly connected to a bidirectional lead screw, one end of the bidirectional lead screw being rotatably connected to the baffle, and a pair of limiting plates threadedly connected to the bidirectional lead screw, one end of each of the two limiting plates passing through a limiting hole on the worktable and fixedly connected to a first fixing plate and a second fixing plate respectively, a sealing gasket provided on one side of the first fixing plate and the second fixing plate, a connecting pipe provided on the first fixing plate, and a dust suction head provided on one side of the connecting pipe, one end of the connecting pipe being connected to a dust suction hose, one end of the dust suction hose being connected to a vacuum cleaner, and a placement plate provided at the upper end of the worktable, on which a throttle valve is placed, and a grinding assembly provided on the second fixing plate.

[0006] As a preferred technical solution of this utility model, the grinding assembly is as follows: a bracket is fixedly connected to one side of the worktable, a first electric telescopic rod is provided on the bracket, a second motor is fixedly connected to the output end of the first electric telescopic rod, a crossbar is fixedly connected to the output end of the second motor, and one end of the crossbar passes through a second fixed plate and is fixedly connected to the grinding wheel.

[0007] As a preferred embodiment of this invention, the sealing gasket is made of rubber.

[0008] As a preferred embodiment of this utility model, a pair of vertical plates are fixedly connected to the upper end of the placement plate.

[0009] As a preferred embodiment of this utility model, a second electric telescopic rod is provided on the vertical plate, and an arc-shaped clamp is fixedly connected to the output end of the second electric telescopic rod.

[0010] As a preferred embodiment of this utility model, a control panel is provided at the upper end of the workbench.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: First, activate the first electric telescopic rod, which drives the second motor, the crossbar, and the grinding wheel on the crossbar to move towards the throttle valve until one end of the grinding wheel reaches the opening of the throttle valve. Simultaneously, activate the first motor, which drives the double-acting screw to rotate. The rotation of the double-acting screw causes the two limiting plates to move towards each other. The limiting plates move more stably under the limiting action of the limiting holes. The movement of the two limiting plates simultaneously drives the first and second fixed plates to move until the sealing gaskets on one side of the first and second fixed plates are in tight contact with the throttle valve. Then activate the second... The first motor drives the grinding wheel to rotate, and by activating the first electric telescopic rod, the grinding wheel moves laterally, thus effectively grinding the inner wall of the throttle valve. Simultaneously, the vacuum cleaner is activated, allowing the grinding debris to pass through the suction head, connecting pipe, and suction hose into the vacuum cleaner. This device effectively prevents debris from splashing and contaminating the workbench, thus avoiding any threat to the health of the workers. Attached Figure Description

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort. Example

[0014] Please refer to Figures 1-3 As shown, this utility model provides a high-precision grinding device for a throttle valve. The sealing gasket 9 is made of rubber. A pair of vertical plates 22 are fixedly connected to the upper end of the placement plate 15. A second electric telescopic rod 23 is provided on the vertical plate 22, and an arc-shaped clamping plate 24 is fixedly connected to the output end of the second electric telescopic rod 23. A control panel 25 is provided at the upper end of the workbench 1. The first motor 3, vacuum cleaner 13, first electric telescopic rod 18, second motor 19 and second electric telescopic rod 23 can be controlled through the control panel 25. All of them are electrically connected to an external power source to ensure that they can be used normally.

[0015] When in use, first place the throttle valve 16 on the upper end of the placement plate 15. At the same time, the two second electric telescopic rods 23 can be started through the control panel 25. The two second electric telescopic rods 23 can drive the two arc-shaped clamps 24 to move towards each other, so that the arc-shaped clamps 24 can clamp and fix the throttle valve 16 well.

[0016] As a further implementation of this embodiment, such as Figures 1-4As shown, a pair of baffles 2 are fixedly connected to the lower end of the workbench 1. A first motor 3 is provided on one side of the baffle 2. The output end of the first motor 3 passes through the baffle 2 and is fixedly connected to a bidirectional lead screw 4. One end of the bidirectional lead screw 4 is rotatably connected to the baffle 2, and a pair of limiting plates 5 are threaded onto the bidirectional lead screw 4. One end of each limiting plate 5 passes through a limiting hole 6 on the workbench 1 and is fixedly connected to a first fixed plate 7 and a second fixed plate 8, respectively. A sealing gasket 9 is provided on one side of both the first fixed plate 7 and the second fixed plate 8. A connecting pipe 10 is provided on the first fixed plate 7, and a dust suction head 11 is provided on one side of the connecting pipe 10. A dust suction hose 12 is connected to one end of the connecting pipe 10. The vacuum hose 12 has a certain degree of flexibility. One end of the vacuum hose 12 is connected to the vacuum cleaner 13. The upper end of the workbench 1 is provided with a placement plate 15, on which a throttle valve 16 is placed. The second fixed plate 8 is provided with a grinding assembly. The grinding assembly is as follows: a bracket 17 is fixedly connected to one side of the workbench 1. A first electric telescopic rod 18 is provided on the bracket 17. A second motor 19 is fixedly connected to the output end of the first electric telescopic rod 18. A crossbar 20 is fixedly connected to the output end of the second motor 19. One end of the crossbar 20 passes through the second fixed plate 8 and is fixedly connected to the grinding wheel 21. The grinding wheel 21 contacts the throttle valve 16 through the side and performs grinding treatment.

[0017] In use, firstly, start the first electric telescopic rod 18, which drives the second motor 19, the crossbar 20, and the grinding wheel 21 on the crossbar 20 to move towards the throttle valve 16 until one end of the grinding wheel 21 moves to the opening of the throttle valve 16. Simultaneously, start the first motor 3, which drives the double-acting screw 4 to rotate. The rotation of the double-acting screw 4 causes the two limiting plates 5 to move towards each other. The limiting plates 5 can move more stably under the limiting action of the limiting holes 6. The movement of the two limiting plates 5 can simultaneously drive the first fixed plate 7 and the second fixed plate 8 to move, until the sealing gasket 9 on one side of the first fixed plate 7 and the second fixed plate 8 are in close contact with the throttle valve 16. Then start the motor 19. The second motor 19 drives the grinding wheel 21 to rotate. By activating the first electric telescopic rod 18, the first electric telescopic rod 18 indirectly drives the grinding wheel 21 to move laterally, thereby effectively grinding the inner wall of the throttle valve 16. At the same time, the vacuum cleaner 13 is activated. Under the action of the vacuum cleaner 13, the debris generated during the grinding process can enter the vacuum cleaner 13 through the vacuum head 11, connecting pipe 10, and vacuum hose 12. This device can effectively prevent the debris generated during the grinding process from flying and contaminating the workbench 1 and posing a threat to the health of the staff.

[0018] Specific working principle: In use, firstly, the throttle valve 16 is placed on the upper end of the placement plate 15. Simultaneously, the two second electric telescopic rods 23 can be activated via the control panel 25. These two electric telescopic rods 23 drive the two arc-shaped clamping plates 24 to move towards each other, thus effectively clamping and fixing the throttle valve 16. Next, the first electric telescopic rod 18 is activated, causing it to drive the second motor 19, the crossbar 20, and the grinding wheel 21 on the crossbar 20 to move towards the throttle valve 16 until one end of the grinding wheel 21 reaches the opening of the throttle valve 16. Simultaneously, the first motor 3 is activated, driving the bidirectional lead screw 4 to rotate. The rotation of the bidirectional lead screw 4 causes the two limiting plates 5 to move towards each other. The limiting plates 5 move more stably under the limiting action of the limiting holes 6. The movement of the two limiting plates 5 simultaneously drives... The first fixed plate 7 and the second fixed plate 8 move until the sealing gasket 9 on one side of the first fixed plate 7 and the second fixed plate 8 are in close contact with the throttle valve 16. Then, the second motor 19 is started, which drives the grinding wheel 21 to rotate. Then, by starting the first electric telescopic rod 18, the first electric telescopic rod 18 indirectly drives the grinding wheel 21 to move laterally, so that the inner wall of the throttle valve 16 can be ground well. At the same time, the vacuum cleaner 13 is started. Under the action of the vacuum cleaner 13, the debris generated during the grinding process can enter the vacuum cleaner 13 through the vacuum head 11, the connecting pipe 10 and the vacuum hose 12. This device can effectively allow the debris generated during the grinding process to enter the vacuum cleaner 13 through the vacuum head 11, the connecting pipe 10 and the vacuum hose 12, avoiding debris splashing and contaminating the workbench 1 and threatening the health of the staff.
