Description

Technical Field

[0001] This utility model belongs to the field of hydraulic valve body processing technology, and relates to a burr removal device for hydraulic valve body. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressurized oil of a distribution valve and is usually used in combination with a solenoid distribution valve. It can be used for remote control of the on / off of oil, gas, and water pipeline systems in hydropower stations. The machining of a hydraulic valve body includes drilling, milling, and heat treatment. During drilling, burrs are left on the inner wall of the hole, which need to be deburred.

[0003] A burr removal device for a hydraulic valve body disclosed in Chinese patent CN211615105U has a support frame fixedly connected to the upper surface of the base, and the upper end of the support frame is connected through the interior of the movable frame. Rollers are rotatably connected to the front and rear sides of the interior of the movable frame, and fixed rods are connected through the front and rear ends of the movable frame. A return spring is sleeved on the outer side of the fixed rod, and a first connecting plate is fixedly connected to the upper end of the fixed rod. A handle is fixedly connected to the middle of the upper surface of the first connecting plate, and a second connecting plate is fixedly connected to the lower end of the fixed rod. A driving device is fixedly connected to the middle of the lower surface of the second connecting plate, and an abrasive brush is fixedly connected to the output end of the driving device.

[0004] This deburring device polishes different parts of the hydraulic valve body by pushing a movable frame to slide on a support frame. However, the movable frame is not positioned on the support frame, making it easy for operators to collide with the abrasive brush when handling the hydraulic valve body on the fixed plate, which is inconvenient for operation.

[0005] To address the aforementioned problems, this utility model proposes a burr removal device for hydraulic valve bodies. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a burr removal device for hydraulic valve bodies.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a base, two support plates are symmetrically fixedly connected to the middle of the top surface of the base, a clamping plate is slidably arranged between the two support plates, a cylinder is fixedly connected inside the base, and the bottom end of the clamping plate is fixedly arranged at the telescopic end of the cylinder.

[0008] The top surface of the base is provided with a semi-circular sliding groove, on which a sliding plate is slidably mounted. A mounting block is connected to the side of the sliding plate near the middle of the base by a spring, and a grinding component is provided on the side of the mounting block away from the sliding plate.

[0009] The top surface of the base is vertically and slidably provided with limit blocks at both ends of the slide groove. The top of each limit block can be slidably set in the bottom surface of the mounting block. The telescopic end of the cylinder is provided with a transmission component. When the telescopic end of the cylinder pushes the clamping plate to move, the transmission component drives the two limit blocks to move up or down.

[0010] Furthermore, a limiting groove is provided on the top surface of the base, the bottom end of the clamping plate is slidably connected to the inside of the limiting groove, and the telescopic end of the cylinder slides through the inner wall of the limiting groove.

[0011] Furthermore, the transmission assembly includes a connecting plate, the base has an internal movable cavity, the connecting plate is slidably connected to the inside of the movable cavity, a connecting rod is fixedly connected between the bottom end of the connecting plate and the clamping plate, and the bottom ends of the two limiting blocks are slidably disposed in the movable cavity;

[0012] Both ends of the connecting plate are fixedly connected to wedge blocks, and the wedge blocks correspond one-to-one with the limiting blocks. One end of the bottom of the limiting block is provided with a rounded corner, and the rounded corner of the limiting block abuts and slides against the inclined surface of the corresponding wedge block.

[0013] Furthermore, the support plate is U-shaped, and L-shaped clamping blocks are fixedly connected to both ends of the top surface of the clamping plate. Hydraulic valve bodies are movably arranged on the two support plates and the clamping plate.

[0014] Furthermore, a slider is fixedly connected to the bottom of the slide plate, the slider is slidably connected to the inside of the slide groove, two slide rods slide symmetrically through the slide plate, a mounting block is fixedly connected to one end of the two slide rods, and the other end of the two slide rods is fixedly connected to the same handle;

[0015] There are two springs, each sleeved on one of the two slide bars. One end of the spring is fixedly connected to one side of the handle, and the other end of the spring is fixedly connected to one side of the slide.

[0016] Furthermore, the polishing assembly includes an abrasive brush, and a motor is fixedly installed inside the mounting block, with the abrasive brush fixedly mounted on the output shaft of the motor.

[0017] Furthermore, the bottom surface of the mounting block is provided with a groove, and the top ends of the two limiting blocks can be movably engaged inside the groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The burr removal device inside the hydraulic valve body is equipped with a limiting block. After the burr removal is completed, the telescopic end of the cylinder pulls the connecting plate to move, causing the wedge block to move towards the limiting block. The inclined surface of the wedge block pushes the rounded corner at the bottom of the limiting block, causing the limiting block to move upward and the top of the limiting block to be stuck in the groove on the bottom surface of the mounting block, thereby positioning the mounting block, positioning the slide plate on the slide groove, positioning the abrasive brush, and facilitating the removal of the hydraulic valve body.

[0020] 2. The burr removal device inside the hydraulic valve body is equipped with a connecting rod. The connecting rod fixes the connecting plate and the clamping plate together. When the cylinder pushes the clamping plate to move and fix the hydraulic valve body, it will push the wedge block to move through the connecting rod, so that the wedge block leaves the limit block, thereby releasing the restriction on the mounting block and making it easier to move the abrasive brush. Conversely, the mounting block can be positioned at the same time as the clamping plate is moved. No separate operation is required, making it convenient to use. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] like Figures 1-5As shown, the technical solution adopted by this utility model is as follows: A burr removal device for a hydraulic valve body includes a base 1, two support plates 9 are symmetrically fixedly connected to the middle of the top surface of the base 1, and a clamping plate 10 is slidably arranged between the two support plates 9. A cylinder 13 is fixedly connected inside the base 1, and the bottom end of the clamping plate 10 is fixedly arranged at the telescopic end of the cylinder 13.

[0029] A limiting groove 18 is formed on the top surface of the base 1, and the bottom end of the clamping plate 10 is slidably connected to the inside of the limiting groove 18. The telescopic end of the cylinder 13 slides through the inner wall of the limiting groove 18. The end of the telescopic end of the cylinder 13 is fixedly connected to one side of the clamping plate 10, and the bottom end of the clamping plate 10 is pushed to slide in the limiting groove 18 by the cylinder 13.

[0030] The support plate 9 is U-shaped, and L-shaped clamping blocks 19 are fixedly connected to both ends of the top surface of the clamping plate 10. Hydraulic valve bodies 12 are movably mounted on the two support plates 9 and the clamping plate 10. By moving the clamping plate 10, the clamping blocks 19 abut against the outer surface of the hydraulic valve body 12, thereby fixing the hydraulic valve body 12.

[0031] A semi-circular groove 2 is provided on the top surface of the base 1, and a sliding plate 3 is slidably mounted on the groove 2. A mounting block 7 is connected to the side of the sliding plate 3 near the middle of the base 1 by a spring 5.

[0032] A slider is fixedly connected to the bottom of the slide plate 3, and the slider is slidably connected inside the slide groove 2. Through the cooperation between the slider and the slide groove 2, the slide plate 3 is positioned on the slide groove 2.

[0033] Two sliding rods 4 slide symmetrically through the skateboard 3, and a mounting block 7 is fixedly connected to one end of each sliding rod 4. The other end of each sliding rod 4 is fixedly connected to the same handle 6. Pulling the handle 6 moves the sliding rod 4, thereby moving the mounting block 7.

[0034] Two springs 5 ​​are provided, each sleeved on one of the two slide rods 4. The springs 5 ​​are sleeved on the slide rods 4 between the handle 6 and the slide plate 3. One end of each spring 5 is fixedly connected to one side of the handle 6, and the other end is fixedly connected to one side of the slide plate 3. In the initial state, the springs 5 ​​pull the handle 6 towards the side closer to the slide plate 3, creating a distance between the slide plate 3 and the mounting block 7.

[0035] A polishing component is provided on the side of mounting block 7 away from the skateboard 3.

[0036] The grinding assembly includes an abrasive brush 8. A motor is fixedly installed inside the mounting block 7, and the abrasive brush 8 is fixedly mounted on the output shaft of the motor. The motor drives the abrasive brush 8 to rotate, causing the abrasive brush 8 to grind the wall of the hole inside the hydraulic valve body 12, thereby removing burrs.

[0037] Limiting blocks 11 are vertically slidably installed on the top surface of the base 1 at both ends of the slide groove 2, and the top ends of the two limiting blocks 11 can be slidably installed within the bottom surface of the mounting block 7. The limiting blocks 11 can be used to position the mounting block 7 at the ends of the slide groove 2.

[0038] The bottom surface of the mounting block 7 has a groove, and the tops of the two limiting blocks 11 can be movably engaged inside the groove. When the mounting block 7 contacts the sliding plate 3, the limiting blocks 11 move upward and can be engaged in the groove, thereby positioning the mounting block 7.

[0039] The telescopic end of cylinder 13 is equipped with a transmission component. When the telescopic end of cylinder 13 pushes the clamping plate 10 to move, the transmission component drives the two limit blocks 11 to move upward or downward.

[0040] The transmission assembly includes a connecting plate 15. A movable cavity 16 is formed inside the base 1, and the connecting plate 15 is slidably connected to the inside of the movable cavity 16. A connecting rod 14 is fixedly connected between the connecting plate 15 and the bottom end of the clamping plate 10. When the cylinder 13 pushes the clamping plate 10 to move, it will push the connecting plate 15 to slide inside the movable cavity 16 via the connecting rod 14.

[0041] The bottom ends of both limiting blocks 11 are slidably set inside the movable cavity 16.

[0042] Both ends of the connecting plate 15 are fixedly connected to wedge blocks 17, which correspond one-to-one with the limiting blocks 11. One end of the bottom of the limiting block 11 is provided with a rounded corner, which abuts against and slides with the inclined surface of the corresponding wedge block 17. When the connecting plate 15 moves the wedge blocks 17, the inclined surface of the wedge blocks 17 pushes the rounded corner of the limiting block 11, thereby pushing the limiting block 11 to move upward.

[0043] Working principle:

[0044] In use, place the hydraulic valve body 12 on the two support plates 9, adjust the position of the hydraulic valve body 12 so that the hole in the middle of the hydraulic valve body 12 is located at the top of the clamping plate 10 and between the two clamping blocks 19.

[0045] When cylinder 13 is activated, its telescopic end pushes the bottom end of clamping plate 10 to slide within the limiting groove 18. The top end of clamping plate 10 drives clamping block 19 to move, causing the top end of clamping block 19 to move towards the top of hydraulic valve body 12.

[0046] The clamping plate 10 drives the connecting plate 15 to slide within the movable cavity 16 via the connecting rod 14. The connecting plate 15 drives the two wedge blocks 17 to move. The wedge blocks 17 gradually move away from the bottom surface of the limiting block 11, and the limiting block 11 slides downward under the action of gravity.

[0047] After the wedge block 17 leaves the limiting block 11, the bottom end of the limiting block 11 slides into the movable cavity 16, causing the top end of the limiting block 11 to leave the mounting block 7. At the same time, the clamping block 19 clamps and fixes the hydraulic valve body 12.

[0048] After the limiting block 11 moves out of the groove on the bottom surface of the mounting block 7, the spring 5 pulls the handle 6 towards the slide plate 3. The handle 6 drives the slide rod 4 to slide on the slide plate 3, causing the mounting block 7 to move away from the slide plate 3. This pushes the abrasive brush 8 into the hole in one of the support plates 9 of the hydraulic valve body 12.

[0049] The motor is started to drive the abrasive brush 8 to rotate, so that the abrasive brush 8 polishes the inner wall of the hole, thereby removing burrs.

[0050] After polishing, pull handle 6 away from the side of the slide plate 3 to move the abrasive brush 8 out of the hydraulic valve body 12. This will stretch spring 5.

[0051] Push handle 6 to make the bottom of slide plate 3 slide in slide groove 2, which will move mounting block 7 and abrasive brush 8. Until the abrasive brush 8 is moved to correspond to the hole on clamping plate 10, release handle 6. Spring 5 will push abrasive brush 8 into the corresponding hole to perform deburring operation on the hole.

[0052] Next, the abrasive brush 8 is pushed into the hole in another support plate 9 of the hydraulic valve body 12 to perform deburring.

[0053] After deburring is completed, push the slide plate 3 to one end of the slide groove 2. Pull the handle 6 to move the mounting block 7 to one side of the slide plate 3. At this time, the groove on the bottom surface of the mounting block 7 corresponds vertically with one of the limiting blocks 11.

[0054] Activate cylinder 13. The telescopic end of cylinder 13 pulls the clamping plate 10 to move, causing the end of clamping block 19 to gradually move away from the top surface of hydraulic valve body 12. This causes clamping plate 10 to no longer clamp hydraulic valve body 12.

[0055] The clamping plate 10 moves the connecting plate 15 and the wedge block 17 via the connecting rod 14. The inclined surface of the wedge block 17 pushes the limiting block 11 upward until the top of one of the limiting blocks 11 is engaged in the groove on the bottom surface of the mounting block 7, thereby fixing the mounting block 7 and positioning the slide plate 3 in the slide groove 2. Then, the hydraulic valve body 12 on the support plate 9 can be removed.

[0056] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
