Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve block processing technology, and in particular to an adjustable fixture for hydraulic valve block processing. Background Technology

[0002] Hydraulic valve blocks are typically made of materials such as cast iron, cast steel, or forged steel, and have a specific shape and size. They are internally machined with various oil passages, hole systems, and mounting surfaces. Hydraulic valve blocks are widely used in equipment such as CNC machine tools, injection molding machines, die casting machines, cranes, and elevators.

[0003] Currently, when processing hydraulic valve blocks, a limiting component is used to limit their movement before drilling. After drilling one set of hydraulic valve blocks, the operator needs to remove the drilled blocks before placing and limiting the next set of blocks. This process results in long downtime for the drill bit, wasting considerable time for the operator to install and remove the valve blocks, leading to low drilling efficiency. A search revealed that the technical solution provided by utility model application number CN202322395217.4 also suffers from the same problems. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable fixture for machining hydraulic valve blocks. While the operator is drilling a hydraulic valve block on one set of limiting components, the operator can also load and unload a hydraulic valve block on another set of limiting components, so that the drilling operation and the loading and unloading operations can be carried out simultaneously, thereby shortening the downtime of the drilling equipment and improving the drilling efficiency.

[0005] To achieve the above objectives, an adjustable fixture for machining hydraulic valve blocks is provided, comprising: an operating table and a limiting assembly. The operating table has an internal groove, and a rotary cylinder is fixedly connected to the inner wall of the groove. The output shaft of the rotary cylinder is fixedly connected to a turntable. The operating table has an internal circular track, and a pulley is installed inside the circular track. The upper surface of the pulley is fixedly connected to the turntable. A placement plate is fixedly connected to the upper surface of the turntable, and a fixing plate is fixedly connected to the upper surface of the placement plate. The limiting assembly includes a first cylinder, a limiting plate, a second electric telescopic rod, a moving plate, and an anti-slip strip. The output end of the first cylinder is fixedly connected to the limiting plate. The inner surface of the limiting plate is fixedly connected to the second electric telescopic rod. The end of the second electric telescopic rod away from the limiting plate is fixedly connected to the moving plate. The side surface of the moving plate is fixedly connected to the anti-slip strip.

[0006] According to the adjustable fixture for machining hydraulic valve blocks, the left surface of the fixing plate is fixedly connected to the first cylinder, and the fixing plate supports the first cylinder.

[0007] According to the adjustable fixture for machining hydraulic valve blocks, the lower surface of the limiting plate is slidably connected to the placement plate, the lower surface of the moving plate is slidably connected to the placement plate, and the lower surface of the anti-slip strip is slidably connected to the placement plate.

[0008] According to the adjustable fixture for machining hydraulic valve blocks, a fixed frame is fixedly connected to the upper surface of the operating table, and a second cylinder is fixedly connected to the upper surface of the fixed frame.

[0009] According to the adjustable fixture for machining hydraulic valve blocks, the output end of the second cylinder is fixedly connected to a fixed box, the inside of the fixed box is provided with a cavity, the bottom inner wall of the cavity is fixedly connected to a motor, and the output end of the motor is fixedly connected to a rotating shaft.

[0010] According to the adjustable fixture for machining hydraulic valve blocks, a drill bit is fixedly connected to the lower surface of the rotating shaft, and the side surface of the rotating shaft is rotatably connected to the fixed box. By starting the motor to drive the rotating shaft and the drill bit to rotate, drilling can be performed on the hydraulic valve block.

[0011] According to the adjustable fixture for machining hydraulic valve blocks, a support frame is fixedly connected to the lower surface of the operating table, and the support frame provides support for the device.

[0012] According to the adjustable fixture for processing hydraulic valve blocks, a baffle is fixedly connected to the upper surface of the turntable. When a set of hydraulic valve blocks is being drilled, the operator is loading and unloading another set of placement plates. The baffle is designed to prevent the drilling operation from affecting the loading and unloading operators.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] By setting up an operating platform, rotary cylinder, turntable, circular track, slide rail, first electric telescopic rod, placement plate, and limiting components, the operator can simultaneously perform drilling operations on the hydraulic valve blocks on one set of limiting components and load and unload hydraulic valve blocks on another set of limiting components. This allows drilling operations to be performed concurrently with loading and unloading operations, thereby shortening the downtime of the drilling equipment, improving drilling efficiency, and limiting the hydraulic valve blocks of different sizes on the front, back, left, and right sides. This enables the hydraulic valve blocks to better resist the cutting force of drilling, reduce vibration and displacement, thus ensuring the stability of the processing process, helping to improve the surface quality and reduce surface roughness.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5This utility model discloses an adjustable fixture for machining hydraulic valve blocks, comprising: an operating table 1 and a limiting component 23. The operating table 1 has a groove 2 inside, and a rotary cylinder 3 is fixedly connected to the bottom inner wall of the groove 2. The output shaft of the rotary cylinder 3 is fixedly connected to a turntable 4. A circular track 5 is provided inside the operating table 1, and a pulley 6 is provided inside the circular track 5. The upper surface of the pulley 6 is fixedly connected to the turntable 4, and a placement plate 8 is fixedly connected to the upper surface of the turntable 4. Activating the rotary cylinder 3 drives the turntable 4 to rotate, and the turntable 4... The pulley 6 moves on the circular track 5. The placement plate 8 and the limiting components 23 are symmetrically arranged in two sets. While the operator is drilling on the hydraulic valve block on one set of limiting components 23, the operator can load and unload the hydraulic valve block on the other set of limiting components 23. This allows the drilling operation to be carried out simultaneously with the loading and unloading operations, thereby shortening the downtime of the drilling equipment and improving the drilling efficiency. The upper surface of the turntable 4 is fixedly connected to the baffle 7. The baffle 7 is set to prevent the drilling operation from affecting the loading and unloading operators.

[0026] A fixing plate 9 is fixedly connected to the upper surface of the placement plate 8. The left surface of the fixing plate 9 is fixedly connected to the first cylinder 10. The fixing plate 9 supports the first cylinder 10. The limiting assembly 23 includes the first cylinder 10, the limiting plate 11, the second electric telescopic rod 12, the moving plate 13, and the anti-slip strip 14. The output end of the first cylinder 10 is fixedly connected to the limiting plate 11. The lower surface of the limiting plate 11 is slidably connected to the placement plate 8. When the first cylinder 10 is activated, it moves the limiting plate 11 to limit the left and right sides of the hydraulic valve block. The inner surface of the limiting plate 11 is fixedly connected to the second electric telescopic rod 12. The second electric telescopic rod 12 is located away from the limiting plate. One end of 11 is fixedly connected to the movable plate 13. The side surface of the movable plate 13 is fixedly connected to the anti-slip strip 14. The lower surface of the movable plate 13 is slidably connected to the placement plate 8. The lower surface of the anti-slip strip 14 is slidably connected to the placement plate 8. When the second electric telescopic rod 12 is activated, the movable plate 13 and the anti-slip strip 14 are moved, which can limit the front and rear sides of the hydraulic valve block. This structure can limit the front, back, left and right sides of hydraulic valve blocks of different sizes, so that the hydraulic valve block can better resist the cutting force of drilling, reduce vibration and displacement, thereby ensuring the stability of the processing process, helping to improve the surface quality of the processed surface and reduce the surface roughness.

[0027] A fixed frame 15 is fixedly connected to the upper surface of the operating table 1. A second cylinder 16 is fixedly connected to the upper surface of the fixed frame 15. A fixed box 17 is fixedly connected to the output end of the second cylinder 16. Activating the second cylinder 16 moves the fixed box 17, which can adjust the height of the fixed box 17 and, consequently, the height of the drill bit 21 on the fixed box 17. The fixed box 17 has a cavity 18 inside. A motor 19 is fixedly connected to the bottom inner wall of the cavity 18. A rotating shaft 20 is fixedly connected to the output end of the motor 19. The side surface of the rotating shaft 20 is rotatably connected to the fixed box 17. A drill bit 21 is fixedly connected to the lower surface of the rotating shaft 20. Activating the motor 19 rotates the rotating shaft 20 and the drill bit 21, which can perform drilling operations on the hydraulic valve block. During drilling, activating the second cylinder 16 moves the drill bit 21 to adjust the drilling depth. A support frame 22 is fixedly connected to the lower surface of the operating table 1, which supports the device.

[0028] Working Principle: During use, a set of hydraulic valve blocks requiring drilling is placed on the placement plate 8. The first cylinder 10 is activated, moving the limiting plate 11 to limit the hydraulic valve blocks on both sides. The second electric telescopic rod 12 is activated, moving the moving plate 13 and anti-slip strip 14 to limit the hydraulic valve blocks on both the front and rear sides. The rotary cylinder 3 is activated, rotating the turntable 4. The pulley 6 under the turntable 4 moves on the circular track 5, causing the limited hydraulic valve blocks to rotate to the drill bit 21 side. The second cylinder 16 is activated, moving the drill bit 21 downwards to adjust its height. The motor 19 is activated, rotating the shaft 20 and the drill bit 21 to perform the drilling operation. While one set of hydraulic valve blocks is being drilled, the operator loads another set of hydraulic valve blocks onto the placement plate 8. After drilling is completed on one side of the drill bit 21, the hydraulic valve blocks are connected to the other placement plate. After the material on plate 8 is loaded, the rotary cylinder 3 is started to drive the turntable 4 to rotate, so that the positions of the two sets of placement plates 8 are swapped. The above operation is repeated to drill holes in the hydraulic valve blocks near the drill bit 21. The operator unloads the hydraulic valve blocks after the previous set of holes is completed and loads the next set of hydraulic valve blocks that need to be drilled. While the operator is drilling the hydraulic valve blocks on one set of limiting components 23, the operator can load and unload the hydraulic valve blocks on the other set of limiting components 23 at the same time, so that the drilling operation and the loading and unloading operations are carried out simultaneously, thereby shortening the downtime of the drilling equipment, improving the drilling efficiency, and limiting the hydraulic valve blocks of different sizes on the front, back, left and right sides, so that the hydraulic valve blocks can better resist the cutting force of drilling, reduce vibration and displacement, thereby ensuring the stability of the processing process and helping to improve the surface quality of the processed surface.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
