Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve processing technology, specifically a drilling device for hydraulic valve processing. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil, playing a control and regulation role in a hydraulic system. In the process of machining a hydraulic valve, in order to construct a hydraulic oil flow channel network and realize the core function of controlling the flow of oil to drive the actuator, it is necessary to use a drilling device for hydraulic valve machining to drill holes on the surface of the valve body.

[0003] In the prior art, patent publication number CN 220739531 U discloses a drilling device for a hydraulic valve block, including a base, a rotating assembly at the upper end of the base, a clamping assembly fixedly connected to the upper end of the rotating assembly, and a longitudinal adjustment assembly fixedly connected to the upper end of the base. This drilling device for a hydraulic valve block can use a hydraulic rod to push a push plate and a buffer pad to clamp and fix the valve block placed on the turntable. The buffer pad can provide cushioning protection during clamping, making the clamping tighter while preventing wear on the valve block and affecting its appearance. The rotating assembly can make the turntable rotate 360 ​​degrees to adjust the angle of the valve block. The longitudinal and lateral adjustment assemblies can make the drilling assembly adjust laterally and longitudinally to adjust the drilling position, greatly reducing dead angles during drilling, facilitating flexible adjustment of the valve block drilling position, and improving the practicality of the device and drilling efficiency.

[0004] The following problems exist: When fixing the valve body, the valve block placed on the turntable is clamped and fixed by pushing the push plate and buffer pad with the hydraulic rod. The valve block with a regular shape is fixed firmly, but the valve block with an irregular shape is not fixed firmly. To address this, we propose a drilling device for hydraulic valve processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a drilling device for hydraulic valve processing. The device fixes the valve block through a positioning mechanism and can adapt to valve bodies of different shapes within the range of motion of the positioning claw. This avoids the situation where the drilling work is affected by the movement of the valve block due to instability. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for hydraulic valve processing, including a processing table, an adjustable bearing plate and a drill bit on the upper surface of the processing table, and a positioning mechanism;

[0007] Positioning mechanism: It includes positioning claws, sliding grooves, positioning blocks, rubber pads, limiting blocks, and limiting components. Adjustable positioning claws are provided on both the left and right sides of the upper surface of the support plate. Sliding grooves are opened inside the positioning claws. Positioning blocks are slidably connected to the front and rear sides of the sliding grooves through limiting components. A rubber pad is provided at the end of the positioning block near the center of the support plate. A limiting block is slidably connected to the side of the sliding groove away from the center of the support plate through limiting components. The valve block is fixed by the positioning mechanism. It can adapt to valve bodies of different shapes within the range of motion of the positioning claws, avoiding the situation where the drilling work is affected by the movement of the valve block due to unstable fixing.

[0008] Furthermore, it also includes a microcontroller, which is located on the right side of the processing table. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0009] Furthermore, the positioning mechanism also includes an electric push rod. An electric push rod is provided in the mounting grooves on both the left and right sides of the support plate. The telescopic ends of the electric push rods are fixedly connected to the side of the positioning claw away from the center of the support plate on the same side. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the fixing of the valve body.

[0010] Furthermore, the limiting component includes limiting protrusions and clearance grooves. The top wall of the slide groove is provided with evenly distributed limiting protrusions, and the upper surfaces of the positioning block and the limiting block are provided with clearance grooves. The limiting protrusions are slidably connected to the interior of the clearance groove inside the same slide groove, which facilitates the fixing of irregular valve bodies.

[0011] Furthermore, the upper surface of the processing table is provided with limit rods on both the left and right sides, and a movable plate is slidably connected between the two limit rods. A drill bit is rotatably connected to the lower surface of the movable plate, and a motor is provided on the upper surface of the movable plate. The lower end of the output shaft of the motor is fixedly connected to the upper end of the drill bit, and the input end of the motor is electrically connected to the output end of the microcontroller to facilitate driving the drill bit to rotate.

[0012] Furthermore, a lead screw is rotatably connected inside the fixed seat on the rear side of the upper surface of the processing table. The threaded hole at the rear end of the movable plate is threadedly connected to the outer surface of the lead screw. A second motor is provided on the upper surface of the fixed seat. The lower end of the output shaft of the second motor is fixedly connected to the upper end of the lead screw. The input end of the second motor is electrically connected to the output end of the microcontroller, which facilitates driving the drill bit to move downward.

[0013] Furthermore, the upper surface of the processing table is provided with a two-axis module. The upper surface of the slide inside the upper guide rail of the two-axis module is fixedly connected to the lower surface of the support plate. The input end of the two-axis module is electrically connected to the output end of the microcontroller, which facilitates the movement of the valve body to drill holes at different positions.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This drilling device for hydraulic valve processing has the following advantages:

[0015] The positioning claws on both sides move towards each other until the rubber pad at the end of one of the positioning blocks on the positioning claw contacts the outer surface of the valve body. At this point, the positioning block stops moving, and the positioning claw continues to move. The positioning block slides inside the positioning claw under the push of the outer surface of the valve body until it squeezes the limiting block and slides towards another positioning block. The limiting block then squeezes the other positioning block towards the valve body until the ends of all four positioning blocks in the positioning claws on both sides are in contact with the outer surface of the valve body through the rubber pads, thus fixing the valve body. This allows the positioning claws to adapt to valve bodies of different shapes within their range of motion, avoiding the situation where the drilling work is affected by the movement of the valve blocks due to instability.

[0021] Please see Figure 1-3This embodiment provides a technical solution: a drilling device for hydraulic valve processing, including a processing table 1, an adjustable bearing plate 4 and a drill bit 7 on the upper surface of the processing table 1, a positioning mechanism 3, and a microcontroller 2. The microcontroller 2 is located on the right side of the processing table 1, and its input terminal is electrically connected to an external power source. Limiting rods 5 are provided on both the left and right sides of the upper surface of the processing table 1, and a movable plate 6 is slidably connected between the two limiting rods 5. The drill bit 7 is rotatably connected to the lower surface of the movable plate 6. A motor 8 is provided on the upper surface of the movable plate 6, and the lower end of the output shaft of the motor 8 is fixedly connected to the upper end of the drill bit 7. The input terminal of the motor 8 is electrically connected to the output terminal of the microcontroller 2. A lead screw 10 is rotatably connected inside the fixed base 9 on the rear side of the surface. The threaded hole at the rear end of the movable plate 6 is threadedly connected to the outer surface of the lead screw 10. (A bellows is provided between the inner wall of the fixed base 9 and the upper and lower sides of the movable plate 6. The bellows cover and shield the lead screw 10. When the lead screw 10 rotates, the movable plate 6 drives the bellows on both sides to contract and extend respectively, preventing dust from affecting the threaded transmission of the lead screw 10 and the movable plate 6.) A motor 2 11 is provided on the upper surface of the fixed base 9. The lower end of the output shaft of the motor 2 11 is fixedly connected to the upper end of the lead screw 10. The input end of the motor 2 11 is electrically connected to the output end of the microcontroller 2. A two-axis module 12 is provided on the upper surface of the processing table 1. (The two-axis module 12 is linear...) The system consists of a guide rail (supporting the moving parts and guiding them to move precisely in a straight line, bearing radial and partial axial loads to ensure smooth and accurate movement) and a transmission component (converting the rotational motion of the motor into linear motion, driving the slide to move along the guide rail). The lower guide rail is fixed to the upper surface of the machining table 1, and the lower surface of the upper guide rail is fixedly connected to the upper surface of the slide inside the lower guide rail. The two-axis module 12 is equipped with accordion-style protective covers, which are located between the inner wall of the machining table 1 and the side of the slide. When the two-axis module is working, the slide drives the accordion-style protective covers on both sides to retract and extend respectively, preventing dust from affecting the normal operation of the two-axis module 12. The upper guide rail of the two-axis module 12... The upper surface of the internal slide is fixedly connected to the lower surface of the support plate 4. The input end of the two-axis module 12 is electrically connected to the output end of the microcontroller 2. When motor 1 8 and motor 2 11 are turned on, the output shaft of motor 1 8 drives the drill bit 7 to rotate, and the output shaft of motor 2 11 drives the lead screw 10 to rotate. The rotation of the lead screw 10 drives the threaded movable plate 6 to move downward along the limit rod 5, causing the rotating drill bit 7 to move downward to drill the valve body. After the work is completed, the drill bit returns to its original position. The microcontroller 2 controls the operation of the two-axis module 12, which can drive the support plate 4 to move forward and backward and left and right, thereby realizing the movement of the valve body on the X and Y axes, and enabling drilling at different positions on the surface of the valve body.

[0022] Positioning mechanism 3 includes positioning claws 31, sliding grooves 32, positioning blocks 33, rubber pads 34, limiting blocks 35, and limiting components 37. Adjustable positioning claws 31 are provided on both the left and right sides of the upper surface of the support plate 4. Sliding grooves 32 are formed inside each positioning claw 31. Positioning blocks 33 are slidably connected to the front and rear sides of the sliding grooves 32 via the limiting components 37. Rubber pads 34 are provided at the end of each positioning block 33 closest to the center of the support plate 4, and the side of the sliding groove 32 furthest from the center of the support plate 4 is slidably connected via the limiting components 37. The positioning mechanism 3 includes a limit block 35 (the positioning block 33 is a wedge shape with one side inclined, and the limit block 35 is a trapezoid shape with both sides inclined). The positioning mechanism 3 also includes an electric push rod 36. Electric push rods 36 are installed in the mounting grooves on both the left and right sides of the support plate 4. The telescopic ends of the electric push rods 36 are fixedly connected to the side of the positioning claw 31 away from the center of the support plate 4. The input end of the electric push rod 36 is electrically connected to the output end of the microcontroller 2. The limit assembly 37 includes a limit protrusion 371 and a clearance groove 372. The top wall of the slide groove 32 is provided with evenly spaced... The upper surfaces of the limiting protrusion 371, positioning block 33, and limiting block 35 are all provided with clearance grooves 372. The limiting protrusion 371 is slidably connected to the clearance groove 372 inside the same sliding groove 32. When the operator places the valve body on the support plate 4, under the control of the microcontroller 2, the telescopic shaft of the electric push rod 36 drives the positioning claw 31 to move towards the center of the support plate 4 until the rubber pad 34 contacts the outer surface of the valve body. When the rubber pad 34 at the end of one of the positioning blocks 33 of one of the positioning claws 31 contacts the outer surface of the valve body... At this time, the positioning block 33 stops moving, and the positioning claw 31 continues to move. Under the restriction of the limiting protrusion 371 and the clearance groove 372, the positioning block 33 slides in the positioning claw 31 under the push of the outer surface of the valve body until the positioning block 33 squeezes the limiting block 35 to slide towards another positioning block 33. The limiting block 35 squeezes the other positioning block 33 to move towards the valve body until the ends of the four positioning blocks 33 in the positioning claws on both sides are in contact with the outer surface of the valve body through the rubber pad 34, thus fixing the valve body. After the valve body is fixed.

[0023] The working principle of the drilling device for hydraulic valve processing provided by this utility model is as follows: The operator places the valve body on the support plate 4. Under the control of the microcontroller 2, the telescopic shaft of the electric push rod 36 drives the positioning claw 31 to move towards the center of the support plate 4 until the rubber pad 34 contacts the outer surface of the valve body. When the rubber pad 34 at the end of one of the positioning blocks 33 in one of the positioning claws 31 contacts the outer surface of the valve body, this positioning block 33 stops moving. The positioning claw 31 continues to move. Under the restriction of the limiting protrusion 371 and the clearance groove 372, this positioning block 33 slides in the positioning claw 31 under the push of the outer surface of the valve body until this positioning block 33 squeezes the limiting block 35 and slides towards another positioning block 33. The limiting block 35 squeezes the other positioning block 33. 3. Move towards the valve body until the ends of the four positioning blocks 33 in the positioning claws 31 on both sides are in contact with the outer surface of the valve body through the rubber pads 34, thus fixing the valve body. After the valve body is fixed, turn on motor 1 8 and motor 2 11. The output shaft of motor 1 8 drives the drill bit 7 to rotate, and the output shaft of motor 2 11 drives the lead screw 10 to rotate. The rotation of the lead screw 10 drives the threaded movable plate 6 to move downward along the limit rod 5, causing the rotating drill bit 7 to move downward to drill the valve body. After the work is completed, the drill bit returns to its original position. The microcontroller 2 controls the two-axis module 12 to work. The two-axis module 12 can drive the bearing plate 4 to move forward and backward and left and right, thereby realizing the movement of the valve body on the X and Y axes, and realizing drilling at different positions on the surface of the valve body.

[0024] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32 series, the motor 8 and the motor 11 can be 1FK7 series, and the two-axis module 12 can be an NSK XY-5H series. The microcontroller 2 controls the operation of the electric push rod 36, the motor 8, the motor 11 and the two-axis module 12 using methods commonly used in the prior art.
