Description

Technical Field

[0001] This utility model relates to the field of valve core processing devices, specifically a cutting device for processing the valve core of a speed regulating valve. Background Technology

[0002] As a core component of fluid control systems, the machining accuracy of the speed control valve spool directly affects the valve's sealing and regulating performance. Traditional valve spool machining typically employs turning or milling processes, with the cutting process often relying on linear feed equipment. This involves clamping the valve spool in a fixture and feeding it along a straight path under a cutting blade for cutting or grooving. While such equipment is simple in structure, its unidirectional feed method often necessitates repeated clamping or fixture changes when machining irregular contours or requiring multi-angle cutting, leading to low efficiency and the potential for cumulative errors. With the increasing demand for high-precision hydraulic components, improving the positioning flexibility and machining stability of valve spool cutting has become a pressing issue for the industry.

[0003] Existing linear push-type cutting equipment has the following significant shortcomings: First, the valve core is prone to radial deviation during linear push due to inertia or fixture clearance, resulting in the cut surface not being perpendicular to the valve core axis, affecting the sealing performance of subsequent assembly; Second, for valve cores requiring multi-angle cutting (such as oblique grooves or stepped holes), manual adjustment of fixture angles or tooling changes are required, which is cumbersome and results in poor repeatability and positioning accuracy. Although some improvement solutions use servo motors to drive linear modules to improve push accuracy, they still cannot solve the rigid positioning problem during multi-angle cutting, and the cost is high.

[0004] Therefore, a cutting device for processing the valve core of a speed control valve is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem of easy deviation in linear push, this utility model proposes a cutting device for processing the valve core of a speed regulating valve.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a cutting device for processing the valve core of a speed regulating valve, including a worktable and a rotating fixture. A frame is installed on the top of the worktable, and a cutting part is provided on the frame. The rotating fixture has an L-shaped plate, a gate-shaped plate, and a pin. A gate-shaped plate is installed on the top of the L-shaped plate, and a through hole is opened on the gate-shaped plate. A pin is vertically slidably fitted in the through hole. A three-jaw chuck is installed on the top of the L-shaped plate. A rotating hole is opened on the top of the worktable, and a rotating shaft is rotatably fitted in the rotating hole. A rotating groove is opened on the L-shaped plate to fit the rotating shaft. Insertion holes are opened on both sides of the top of the worktable. An arc-shaped groove is opened on the top of the worktable, and the two ends of the arc-shaped groove are connected to the two insertion holes. The bottom end of the pin is inserted into the insertion hole.

[0007] Preferably, a retaining ring is fitted onto the pin, and a spring connects the retaining ring to the door panel.

[0008] Preferably, the L-shaped plate has a through hole, and the end of the pin slides into the through hole.

[0009] Preferably, a pull block is installed on the outer surface of the three-jaw chuck.

[0010] Preferably, a collection groove is provided on the worktable, and a pushing part is provided in the collection groove. The pushing part has a push block and a threaded rod. The push block is slidably fitted in the collection groove, and the two ends of the threaded rod are connected to the two sides of the collection groove. The push block is provided with a threaded hole for threaded engagement with the threaded rod.

[0011] Preferably, the worktable is provided with two slide grooves, which are located on both sides of the collection groove and connected to it. Slider blocks are installed on both sides of the push block, and the two sliders slide and engage in the corresponding slide grooves respectively.

[0012] Preferably, the top of the workbench is provided with an inclined groove, which is connected to the collection trough.

[0013] Preferably, the cutting section includes a cylinder, a cutting cover, a motor, and a blade. The cylinder is mounted on the top of the frame, the cutting cover is mounted on the output end of the cylinder, the motor is mounted on the side of the cutting cover, and the blade is mounted on the output end of the motor.

[0014] The advantages of this utility model are: 1. This utility model achieves high-precision angle adjustment for valve core cutting through the coordinated design of a rotating clamp and a pin locking mechanism. The rigid fit between the pin and the insertion hole resists cutting vibration, ensuring that the L-shaped plate does not rotate slightly during processing, keeping the valve core center axis perpendicular to the blade at all times, reducing the perpendicularity error of the cutting surface, reducing the number of repeated clamping compared to traditional linear push-type equipment, and ensuring that the constant downward pressure provided by the spring does not dislodge due to vibration during high-speed cutting. It is suitable for heavy cutting conditions of hardened steel valve cores, significantly improving processing accuracy and efficiency. 2. This utility model significantly improves cleaning efficiency and equipment maintainability through an integrated waste collection system. The width of the collection trough matches the cutting range of the blade to collect debris, preventing waste accumulation from affecting the clamp rotation mechanism. The linear advancement of the push block driven by the threaded rod, combined with the inclined groove, enables rapid discharge of waste, effectively solving the problems of decreased processing accuracy and maintenance difficulties caused by waste accumulation in traditional equipment.

[0018] 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 scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a cutting device for processing the valve core of a speed control valve. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6A cutting device for processing the valve core of a speed control valve includes a worktable 1 and a rotary fixture 3. A frame 6 is mounted on the top of the worktable 1, and a cutting section 7 is provided on the frame 6. The rotary fixture 3 has an L-shaped plate 301, a gantry plate 303, and a pin 305. The gantry plate 303 is mounted on the top of the L-shaped plate 301, and a through hole 304 is formed in the gantry plate 303. The pin 305 is vertically slidably fitted in the through hole 304. A three-jaw chuck 4 is mounted on the top of the L-shaped plate 301. A rotating hole 101 is formed on the top of the worktable 1, and a rotating shaft 2 is rotatably fitted in the rotating hole 101. A rotating groove 302 is formed on the L-shaped plate 301 to mate with the rotating shaft 2. The L-shaped plate 301 can rotate on the worktable 1 through the rotating shaft 2. The workbench 1 has two insertion holes 102 on both sides of its top. The top of the workbench 1 has an arc-shaped groove 103, and the two ends of the arc-shaped groove 103 are connected to the two insertion holes 102. The bottom end of the pin 305 is inserted into the insertion hole 102. When the speed control valve core is cut, the valve core is fixed by the three-jaw chuck 4. Then the pin 305 is pulled out from one side insertion hole 102, so that the pull block 401 drives the L-shaped plate 301 to rotate. At this time, the bottom end of the pin 305 slides along the arc-shaped groove 103 until it reaches the other side insertion hole 102 and is inserted, thereby limiting the half-circle rotation of the three-jaw chuck 4. After the bottom end of the pin 305 is inserted into the insertion hole 102, the position of the L-shaped plate 301 can be locked to prevent the L-shaped plate 301 from rotating.

[0020] Reference Figure 5 and Figure 6 A retaining ring 306 is sleeved on the pin 305. A spring 307 is connected between the retaining ring 306 and the door plate 303. The spring 307 always pushes the pin 305 downward to insert into the insertion hole 102. When the pin 305 is pulled to release the limit on the L-shaped plate 301, the retaining ring 306 contacts the bottom surface of the door plate 303 to prevent the pin 305 from moving out of the through hole 304.

[0021] Reference Figure 5 and Figure 6 The L-shaped plate 301 has a through hole 308, and the end of the pin 305 is slidably fitted in the through hole 308. The through hole 308 can ensure that the pin 305 can be accurately inserted into the socket 102 and prevent displacement.

[0022] Reference Figure 5 The outer surface of the three-jaw chuck 4 is equipped with a pull block 401. The pull block 401 can be used to easily pull the three-jaw chuck 4 to drive the L-shaped plate 301 to rotate along the rotating shaft 2.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The workbench 1 is provided with a collection groove 104. A pusher 5 is provided in the collection groove 104. The pusher 5 has a push block 501 and a threaded rod 502. The threaded rod 502 is externally connected to a drive source. The push block 501 is slidably fitted in the collection groove 104. The two ends of the threaded rod 502 are connected to the two sides of the collection groove 104. The push block 501 is provided with a threaded hole that is threaded to fit the threaded rod 502. When cutting, the waste chips fall into the collection groove 104. At this time, the drive source is started to drive the threaded rod 502 to rotate. The push block 501 moves along the threaded rod 502 through the threaded hole, pushing the waste chips out of the collection groove 104.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The workbench 1 is provided with two slide grooves 105. The two slide grooves 105 are located on both sides of the collection groove 104 and are connected to the collection groove 104. The push block 501 is equipped with sliders 503 on both sides. The two sliders 503 are slidably engaged in the corresponding slide grooves 105. When the push block 501 moves, the sliders 503 on both sides slide along the corresponding slide grooves 105 to ensure that the push block 501 does not deviate during movement.

[0025] Reference Figure 4 The top of the workbench 1 is provided with an inclined groove 106, which is connected to the collection groove 104. After the pusher block 501 pushes the waste material into the inclined groove 106, the waste material slides out of the workbench 1 along the inclined groove 106, realizing automatic chip removal.

[0026] Reference Figure 1 and Figure 3 The cutting unit 7 has a cylinder 701, a cutting cover 702, a motor 703, and a blade 704. The cylinder 701 is mounted on the top of the frame 6. The cutting cover 702 is mounted on the output end of the cylinder 701. The motor 703 is mounted on the side of the cutting cover 702. The blade 704 is mounted on the output end of the motor 703. When cutting the valve core, the cylinder 701 controls the lifting and lowering of the cutting cover 702, and the motor 703 drives the blade 704 to rotate, and the blade 704 cuts the valve core.

[0027] Working principle: After the operator clamps the speed control valve core to be processed onto the three-jaw chuck 4, he pulls the pin 305 upward to disengage it from the insertion hole 102, releasing the lock of the L-shaped plate 301. Pulling the pull block 401 rotates the three-jaw chuck 4, the L-shaped plate 301 rotates along the rotating shaft 2, and the pin 305 slides along the arc groove 103 to the position of the insertion hole 102 on the other side. After it is in place, the spring 307 pushes the pin 305 to insert into the insertion hole 102 on the other side, completing the angle fixation. At this time, the motor 703 is started to drive the blade 704 to rotate, and the cylinder 701 pushes the cutting cover 702 to move downward, so that the blade 704 cuts the valve core. The waste generated by cutting falls into the collection groove 104. The operator starts the drive source to drive the threaded rod 502 to rotate, so that the threaded rod 502 drives the push block 501 to move along the collection groove 104. The push block 501 pushes the waste in the collection groove 104 and pushes the waste into the inclined groove 106 for discharge.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
