Description

Technical Field

[0001] The utility model relates to the technical field of drilling holes for speed regulating valves, in particular to a drilling device for producing and processing speed regulating valves. Background Art

[0002] The speed regulating valve is a valve used to control the flow speed of fluids such as hydraulic oil and gas. This valve is widely used in hydraulic systems, pneumatic systems and various mechanical equipment to accurately control the action speed of actuators such as hydraulic cylinders and cylinders. In production and processing, a drilling device is usually used to drill corresponding holes in the valve so that the valve with the holes can meet production requirements.

[0003] After searching, the Chinese patent "A drilling device for high-precision positioning for valve production" authorization announcement number "CN217799087U" realizes the clamping and positioning of the valve through mounting columns, telescopic rods, fixed plates, slots, sliding rods and nuts, ensuring the accuracy of the drilling device in drilling holes in the valve.

[0004] After the slide bars on both sides are pushed to move to corresponding positions, the nuts on the rotating slide bars are abutted against the mounting posts so that the two fixing plates clamp the valve. This method of positioning the valve is too inconvenient.

[0005] Therefore, a drilling device for producing and processing a speed regulating valve is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a drilling device for producing and processing a speed regulating valve in order to solve the above-mentioned problem, thereby improving the problem that the positioning of the valve is too inconvenient.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a drilling device for speed regulating valve production and processing, comprising: a drilling table, the top of the drilling table is fixedly connected with a bracket, and the bottom of the bracket is provided with a drilling rod; a clamping mechanism, the clamping mechanism includes a clamping frame arranged on the top of the drilling table; wherein the clamping mechanism includes two clamping frames slidably connected to the top of the drilling table, the top of the drilling table is slidably connected with two sliding blocks, the top of the sliding block is hinged with a clamping block, the bottom of the drilling table is fixedly connected with a fixed frame, the inner wall of the fixed frame is rotatably connected with two bidirectional screw rods, the lower end of the surface of the clamping frame is threadedly connected to the surface of one of the bidirectional screw rods, the lower end of the surface of the sliding block is threadedly connected to the surface of the other bidirectional screw rod, and the bottom of the drilling table is fixedly connected with two first servo motors, and the output shaft of the first servo motor is fixedly connected to one end of the bidirectional screw rod. By utilizing a bidirectional screw rod, a clamping block, a first servo motor and a clamping plate, it is possible to clamp a valve placed vertically or horizontally, making it more convenient to clamp valves placed in different states, thereby improving the practicability of the drilling device in positioning the valve.

[0008] Preferably, springs are fixedly connected to both sides of the inner wall of the clamping block, one end of the spring is fixedly connected to a fixed rod, and the surface of the fixed rod is clamped to the inner wall of the slider. The spring and the fixed rod are used to position the clamping block on the slider, ensuring the stability of the clamping block vertically on the slider.

[0009] Preferably, a toggle block is fixedly connected to the surface of the fixed rod, and the surface of the toggle block is slidably connected to the lower end of the surface of the clamp block. The toggle block is used to retract the fixed rod into the clamp block, thereby achieving angle adjustment of the clamp block on the slider, ensuring that when positioning and drilling a horizontally placed valve, the clamp block will not affect the drilling process of the horizontally placed valve.

[0010] Preferably, the lower end of the surface of the clamp block is slidably connected to an anti-loosening frame, and the lower end of the surface of the anti-loosening frame is clamped to the inner wall of the toggle block. The anti-loosening frame and the toggle block are used to stably clamp the fixed rod in the slider, thereby achieving the stability of the clamp block on the slider, ensuring that the two clamp blocks stably clamp the valve.

[0011] Preferably, both the front and rear ends of the clamping frame and the slider are fixedly connected with soft sleeves, and one end of the soft sleeve on one side is fixedly connected to the surface of the fixed frame. The soft sleeve is used to protect the surface of the bidirectional screw rod, prevent the waste chips generated during drilling from falling on the surface of the bidirectional screw rod, and reduce the wear between the bidirectional screw rod and the clamping frame and the slider.

[0012] Preferably, the lower ends of the surfaces of the clamping frame and the slider are rotatably connected with rollers, and the surfaces of the rollers are rollingly connected to the top of the fixed frame. The fixed frame and the rollers are used to support the clamping frame and the slider, ensuring that the clamping frame and the slider move smoothly.

[0013] Preferably, the front and rear ends of the clamping frame and the slider are fixedly connected with a scraper, and the bottom of the scraper contacts the top of the fixed frame. The scraper is used to push and sweep the waste debris falling from the top of the fixed frame to prevent the waste debris from affecting the rolling of the roller on the fixed frame.

[0014] Preferably, the upper end of the surface of the clamping frame and the surface of the clamping block are both concave in an arc shape.

[0015] The beneficial effects of the utility model are:

[0016] 1. The bidirectional screw rod, clamping block, first servo motor and clamping plate are used to clamp the valves placed vertically or horizontally. The clamping of valves is more convenient and convenient for clamping valves placed in different states, thus improving the practicality of the drilling device for positioning valves.

[0017] 2. The spring and the fixed rod are used to position the clamp on the slider. The anti-loosening frame and the toggle block are used to stably clamp the fixed rod in the slider, thereby ensuring that the clamp is stably positioned on the slider, ensuring that the two clamps stably clamp the valve. The toggle block is used to retract the fixed rod into the clamp, thereby ensuring that the angle of the clamp on the slider is adjusted, ensuring that when positioning and drilling holes for horizontally placed valves, the clamp will not affect the drilling of the horizontally placed valves.

[0026] The inner wall of the bracket 2 is slidably connected to a moving frame, the inner wall of the moving frame is slidably connected to a moving block, the bottom of the moving block is fixedly connected to an electric push rod, the telescopic end of the electric push rod is fixedly connected to a mounting plate, the bottom end of the mounting plate is fixedly connected to a second servo motor, the output shaft of the second servo motor is fixedly connected to the top of the drilling rod 3, the bracket 2 and the inner wall of the moving frame are both rotatably connected to a lead screw, one end of the lead screw is fixedly connected to a third servo motor, the surface of one third servo motor is fixedly connected to the inner wall of the bracket 2, and the surface of the other third servo motor is fixedly connected to the inner wall of the moving frame.

[0027] When it is necessary to drill a hole in the valve, the valve is placed vertically on the drilling table 1. At this time, one of the first servo motors 46 is manually opened, and the output shaft of one of the first servo motors 46 rotates the bidirectional screw rod 45 to drive the two sliders 42 and the clamping blocks 43 to approach each other, so that the two clamping blocks 43 clamp the vertical valve. At this time, one of the first servo motors 46 is manually closed and the drilling rod 3 is driven to move to a suitable position. The electric push rod and the second servo motor are manually opened, and the telescopic end of the electric push rod moves downward to push the mounting plate, the second servo motor and the drilling rod 3 to move downward. The output shaft of the second servo motor rotates to drive the drilling rod 3 to rotate, and the rotating drilling rod 3 moves downward to drill the vertical valve. After the drilling of the vertical valve is completed, the second servo motor and the electric push rod are manually closed.

[0028] At this time, the two clamping blocks 43 are driven to move away from each other and the placement state of the valve is adjusted so that the valve is placed horizontally on the drilling table 1. Another first servo motor 46 is manually turned on, and the output shaft of the other first servo motor 46 rotates through the bidirectional screw rod 45 to drive the two clamping frames 41 to move closer to each other to clamp the horizontally placed valve. Another first servo motor 46 is manually turned off and the drilling rod 3 is driven to rotate downward to perform drilling operations on the horizontally placed valve. After drilling is completed, the second servo motor and the electric push rod are manually turned off and the two clamping frames 41 are driven to move away from each other to release the clamping state of the valve.

[0029] like Figure 4 As shown, springs 48 are fixedly connected to both sides of the inner wall of the clamping block 43, one end of the spring 48 is fixedly connected to a fixed rod 413, the surface of the fixed rod 413 is clamped to the inner wall of the slider 42, the surface of the fixed rod 413 is fixedly connected to a toggle block 47, the surface of the toggle block 47 is slidably connected to the lower end of the surface of the clamping block 43, the lower end of the surface of the clamping block 43 is slidably connected to an anti-loosening frame 49, and the lower end of the surface of the anti-loosening frame 49 is clamped to the inner wall of the toggle block 47.

[0030] When the two clamping blocks 43 move away from each other, pull the anti-loosening frame 49 to move the anti-loosening frame 49 away from the toggle block 47, push the two toggle blocks 47 to retract the two fixed rods 413 into the clamping block 43, release the lock of the clamping block 43 in the slider 42, push the clamping block 43 to flip the clamping block 43 90 degrees in the slider 42, and make the clamping block 43 lie horizontally, so as to prevent the clamping block 43 in the vertical state from affecting the valve placed horizontally in the drill hole.

[0031] like Figure 5 As shown, both front and rear ends of the clamping frame 41 and the slider 42 are fixedly connected with a soft sleeve 410, wherein one end of the soft sleeve 410 on one side is fixedly connected to the surface of the fixed frame 44. The surface of the bidirectional screw rod 45 is located on the inner side of the soft sleeve 410, and the soft sleeve 410 is a corrugated rubber sleeve.

[0032] like Figure 5As shown, the lower end of the surface of the clamping frame 41 and the slider 42 is rotatably connected with a roller 412, and the surface of the roller 412 is rollingly connected to the top of the fixed frame 44. The front and rear ends of the clamping frame 41 and the slider 42 are fixedly connected with a scraper 411, and the bottom of the scraper 411 contacts the top of the fixed frame 44. During the movement, the clamping frame 41 or the slider 42 drives their respective rollers 412 to roll on the fixed frame 44 and drives the scraper 411 to push and sweep the waste on the fixed frame 44.

[0033] When the utility model is in use, the valve is placed vertically on the drilling table 1, and one of the first servo motors 46 is manually opened at this time. The output shaft of one of the first servo motors 46 rotates the bidirectional screw rod 45 to drive the two sliders 42 and the clamping block 43 to approach each other, so that the two clamping blocks 43 clamp the valve in the vertical state. At this time, one of the first servo motors 46 is manually closed and drives the drilling rod 3 to move to a suitable position, and the electric push rod and the second servo motor are manually opened. The telescopic end of the electric push rod moves downward to push the installation plate, the second servo motor and the drilling rod 3 to move downward, and the output shaft of the second servo motor rotates to drive the drilling rod 3 rotates, the rotating drilling rod 3 moves down to drill the valve in the vertical state. After the drilling of the valve in the vertical state is completed, the second servo motor and the electric push rod are manually closed to drive the two clamping blocks 43 to move away from each other and adjust the placement state of the valve so that the valve is placed horizontally on the drilling table 1. The other first servo motor 46 is manually opened, and the output shaft of the other first servo motor 46 rotates to drive the two clamping frames 41 to move closer to each other through the bidirectional screw rod 45 to clamp the horizontally placed valve.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
