Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically a multi-axis linkage CNC processing device for valve bodies. Background Technology

[0002] As a key component of fluid control systems, the valve body requires drilling during its machining. Current machining (drilling) machine tools mainly suffer from the following problems: (1) Only one valve body can be fixed at a time. After the processing is completed, the valve body needs to be removed and a new valve body needs to be installed, which increases the number of replacements and reduces the processing efficiency.

[0003] (2) During drilling, the drill rod temperature is prone to rise and the cuttings are prone to splashing everywhere. Currently, water is generally sprayed onto the drill rod to reduce the temperature and prevent the cuttings from splashing. However, the water spray pipe is separate from the drill rod and is not integrated together. The sprayed water is prone to deflection due to vibration during the drilling process, making it difficult to spray accurately onto the drill rod. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-axis linkage CNC machining device for valve bodies, thereby solving the problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A multi-axis linkage CNC machining device for valve bodies includes a machine base, a support frame fixed to one end of the machine base, a multi-axis linkage mechanism mounted on the support frame, and a drilling mechanism mounted on the multi-axis linkage mechanism. The drilling mechanism is controlled to move along the X and Y axes by the multi-axis linkage mechanism. A column is rotatably connected to the machine base via bearings. The machine base has a drive cavity, and a rotating mechanism for controlling the rotation of the column is located in the drive cavity. A bearing plate is fixed on the column, and multiple sets of equidistant positioning mechanisms are distributed along the circumference of the bearing plate. The drilling mechanism is located above the positioning mechanisms. The drilling mechanism includes a connecting seat, a U-shaped seat, a cylinder, a lifting plate, a drilling machine, a casing, and a drain pipe. The connecting seat is connected to a multi-axis linkage mechanism. The U-shaped seat is fixedly connected to one end of the connecting seat. The cylinder is installed on the upper end of the U-shaped seat. The lifting plate is slidably connected inside the U-shaped seat. The telescopic end of the cylinder is connected to the lifting plate. The drilling rig is installed on the lifting plate. The casing is fixed to the lower end of the U-shaped seat. The inner diameter of the casing is larger than the diameter of the drill rod. The drill rod passes through the bottom of the casing so that the drill rod can rotate inside the casing without contacting the casing. The drainage pipe is inclinedly connected to one side of the lower part of the casing, and the inner end of the drainage pipe communicates with the inside of the casing. The outer end of the drainage pipe is connected to a water supply device. Water is drawn to the drainage pipe through the water supply device and then sprayed onto the drill rod from the inner end of the drainage pipe.

[0006] Preferably, the multi-axis linkage mechanism includes an X-axis displacement mechanism and a Y-axis displacement mechanism.

[0007] The X-axis displacement mechanism includes first bearing seats fixed at both ends of the top of the support frame, a first lead screw rotatably connected to the two first bearing seats, a first guide rail disposed on the top of the support frame, and a first motor installed at one end of the top of the support frame. The first lead screw is arranged along the X-direction, and the first motor is drivenly connected to the first lead screw. A first slide block is threaded onto the first lead screw, and the first slide block has first sliding grooves on both sides, which are slidably connected to the first guide rail. When the first motor is started, it drives the first lead screw to rotate. When the first lead screw rotates, it drives the first slide block to move along the first guide rail, that is, along the X-axis direction.

[0008] The Y-axis displacement mechanism includes second bearing seats fixed at both ends of the top surface of the first slide, a second lead screw rotatably connected to the two second bearing seats, a second guide rail disposed on the top surface of the first slide, and a second motor mounted on one end of the first slide. The second lead screw is arranged along the Y-axis direction and is perpendicular to the first lead screw. The second motor is driven by the second lead screw. The second lead screw is threadedly connected to the bottom surface of the connecting seat. The bottom surface of the connecting seat is provided with a second sliding groove, and the connecting seat is slidably connected to the second guide rail through the second sliding groove. When the second motor is started, it drives the second lead screw to rotate. When the second lead screw rotates, it drives the second slide to move along the second guide rail, that is, along the Y-axis direction.

[0009] Preferably, the rotating mechanism includes a third motor mounted in the drive cavity, a first gear connected to the motor shaft of the third motor, and a second gear fixed to the column, wherein the first gear meshes with the second gear. When the third motor is started, the column rotates through the engagement of the first and second gears, thereby causing the support plate to rotate.

[0010] Preferably, the positioning mechanism includes a central block fixed to the center of the bearing plate and several sets of clamping units installed on the outer periphery of the bearing plate. Each clamping unit includes a threaded sleeve rotatably connected to the side wall of the bearing plate via a bearing, a screw threaded into the threaded sleeve, a handle connected to the outer wall of the threaded sleeve, a pressure block connected to the inner end of the screw, a limiting block connected to the outer end of the screw, and a guide rod connected to the outer wall of the pressure block. The pressure block is located inside the bearing plate, and the outer end of the guide rod passes through the bearing plate and extends to the outer side of the bearing plate, allowing the guide rod to slide on the bearing plate. The opposing surfaces of the pressure block and the central block are each provided with a V-groove. The valve body is placed between the pressure block and the central block. Rotating the handle rotates the threaded sleeve. As the threaded sleeve rotates, the guide rod causes the screw to move within the threaded sleeve, thereby moving the pressure block and pressing the valve body tightly against the central block to maintain stability.

[0011] Preferably, the bottom of the support plate near the center block has multiple drainage holes; the upper end of the column has a water collection basin, the center of the column has a water passage hole, and the base has a drainage channel. The drainage holes, the water collection basin, the water passage hole, and the drainage channel are connected. The outer end of the drainage channel is connected to a flange, which can be connected to an external pipe for connecting to sewage treatment equipment. Wastewater from the drilling process falls into the support plate, preventing sewage from flowing around and reducing pollution. Water in the support plate enters the water collection basin through the drainage holes, then enters the drainage channel through the water passage hole, and finally is discharged through the drainage channel.

[0012] Preferably, sealing rings are provided on both sides of the drive cavity of the column. The sealing rings prevent water from entering the drive cavity, thereby preventing the rotating mechanism from getting damp.

[0013] Preferably, a control cabinet is provided on one side of the machine base, and a PLC controller is installed inside the control cabinet. A display is installed on the control cabinet, and control buttons are provided on the side of the control cabinet. The first motor, the second motor, the third motor, the cylinder, the drilling rig, the display, and the control buttons are all electrically connected to the PLC controller. The PLC controller contains a control program for controlling the orderly operation of each component.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) Multiple valve bodies are fixed in the bearing plate by the positioning unit. The position of the drilling mechanism is adjusted by the multi-axis linkage mechanism so that the drilling mechanism is above the valve body. The column is rotated by the rotation mechanism, which drives the bearing plate to rotate, so that the valve bodies reach the bottom of the drill rod one by one. The drilling mechanism drills holes in the valve bodies one by one, without the need to frequently replace the valve bodies, thus improving the drilling efficiency.

[0015] (2) During drilling, the drilling machine drives the drill rod to rotate inside the casing. Water enters through the drainage pipe and is accurately sprayed onto the lower part of the drill rod. The water will not be deflected or splashed around due to vibration, which improves the cooling efficiency of the drill rod and also improves the bonding effect between the debris and water, preventing dust from splashing.

Detailed Implementation

[0017] 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.

[0018] Example 1 Please see Figure 1-6 A valve body multi-axis linkage CNC machining device includes a machine base 1, a support frame 2 fixed to one end of the machine base, a multi-axis linkage mechanism 3 mounted on the support frame, and a drilling mechanism 4 mounted on the multi-axis linkage mechanism 3. The drilling mechanism 4 is controlled to move along the X-axis and Y-axis by the multi-axis linkage mechanism 3.

[0019] Specifically, the multi-axis linkage mechanism 3 includes an X-axis displacement mechanism and a Y-axis displacement mechanism.

[0020] The X-axis displacement mechanism includes first bearing seats fixed at both ends of the top of the support frame 2, a first lead screw 301 rotatably connected to the two first bearing seats, a first guide rail 302 disposed on the top of the support frame, and a first motor installed at one end of the top of the support frame. The first lead screw 301 is arranged along the X-direction, and the first motor is drivenly connected to the first lead screw. A first slide block 303 is threadedly connected to the first lead screw 301. The first slide block 303 has first sliding grooves on both sides and is slidably connected to the first guide rail 302 through the first sliding grooves. When the first motor is started, it drives the first lead screw to rotate. When the first lead screw rotates, it drives the first slide block to move along the first guide rail, that is, along the X-axis direction.

[0021] The Y-axis displacement mechanism includes second bearing seats fixed at both ends of the top surface of the first slide, a second lead screw 304 rotatably connected to the two second bearing seats, a second guide rail 305 disposed on the top surface of the first slide, and a second motor 306 mounted on one end of the first slide. The second lead screw 304 is arranged along the Y-axis direction and is perpendicular to the first lead screw 301. The second motor 306 is driven by the second lead screw 304. The second lead screw 304 is threadedly connected to the bottom surface of the connecting seat 401. The bottom surface of the connecting seat 401 is provided with a second sliding groove, and the connecting seat 401 is slidably connected to the second guide rail 305 through the second sliding groove. When the second motor is started, it drives the second lead screw to rotate. When the second lead screw rotates, it drives the second slide to move along the second guide rail, that is, along the Y-axis direction.

[0022] A column 5 is rotatably connected to the base 1 via bearings. The base 1 contains a drive chamber 6, which houses a rotating mechanism 7 for controlling the column's rotation. The rotating mechanism 7 includes a third motor 701 mounted within the drive chamber, a first gear 702 connected to the motor shaft of the third motor, and a second gear 703 fixed to the column. The first gear 702 meshes with the second gear 703. Starting the third motor 701, through the engagement of the first gear 702 and the second gear 703, drives the column 5 to rotate. To ensure the clamping unit rotates at the same angle each time, the number of revolutions of the third motor each time can be set, meaning that after each rotation, the clamping unit reaches below the drill rod.

[0023] In addition, a door is provided on one side of the base located in the drive chamber, which facilitates the maintenance of the rotating mechanism. At the same time, the door is provided with heat dissipation holes to facilitate the cooling of the third motor.

[0024] A support plate 8 is fixed on the column 5. When the column rotates, it will cause the support plate 8 to rotate as well. Multiple sets of equidistant positioning mechanisms 9 are distributed along the circumference inside the support plate 8. The drilling mechanism 4 is located above the positioning mechanisms 9.

[0025] The positioning mechanism 9 includes a center block 901 fixed inside the center of the bearing plate and several sets of clamping units installed on the outer periphery of the bearing plate. In this embodiment, four sets of clamping units are preferred. Each clamping unit includes a threaded sleeve 902 rotatably connected to the side wall of the bearing plate 8 via a bearing, a screw 903 threaded into the threaded sleeve, a handle 904 connected to the outer wall of the threaded sleeve, a pressure block 905 connected to the inner end of the screw, a limiting block 906 connected to the outer end of the screw, and a guide rod 907 connected to the outer wall of the pressure block. The pressure block is located inside the bearing plate, and the outer end of the guide rod 907 passes through the bearing plate 8 and extends to the outer side of the bearing plate 8, allowing the guide rod 907 to slide on the bearing plate 8. The diameter of the limiting block 906 is larger than the inner diameter of the threaded sleeve to prevent the screw from falling out of the threaded sleeve. V-grooves are provided on the opposing surfaces of the pressure block 905 and the center block 901. The valve body can be pressed tightly by the cooperation of the two V-grooves.

[0026] The drilling mechanism 4 includes a connecting seat 401, a U-shaped seat 402, a cylinder 403, a lifting plate 404, a drilling rig 405, a casing 406, and a drainage pipe 407. The connecting seat 401 is connected to the multi-axis linkage mechanism 3 for transmission. The U-shaped seat 402 is fixedly connected to one end of the connecting seat 401. The cylinder 403 is installed on the upper end of the U-shaped seat 402. The lifting plate 404 is slidably connected inside the U-shaped seat 402. The telescopic end of the cylinder 403 is connected to the lifting plate 404. The drilling rig 405 is installed on the lifting plate 404. The casing 406 is fixed to the lower end of the U-shaped seat 402. The inner diameter of the casing 406 is larger than the diameter of the drill rod on the drilling rig. The drill rod passes through the bottom of the casing 406 so that the drill rod can rotate inside the casing without contacting the casing. The drainage pipe 407 is inclinedly connected to one side of the lower part of the casing 406, and the inner end of the drainage pipe 407 is connected to the inside of the casing 406. The outer end of the drainage pipe is connected to the water supply device (not shown in the attached figure). Water is led to the drainage pipe through the water supply device and then sprayed onto the drill rod from the inner end of the drainage pipe.

[0027] A control cabinet 15 is located on one side of the base 1. The control cabinet houses a PLC controller and has a door on one side for easy maintenance. The door also has ventilation holes. A touch-screen display 16 is mounted on the control cabinet, allowing input of operating parameters for each component. Control buttons are located on the side of the control cabinet. The first motor, second motor, third motor, cylinder, drilling rig, display, and control buttons are all electrically connected to the PLC controller.

[0028] The working principle of this embodiment is as follows: Multiple valve bodies 17 are fixed in the bearing plate 8 by the positioning unit 9. The position of the drilling mechanism 4 is adjusted by the multi-axis linkage mechanism 3 so that the drilling mechanism 4 is above the valve body. Then, parameters are input to control the number of rotations of the third motor 701. After multiple adjustments, a parameter is determined so that the valve body 17 can reach the bottom of the drill rod after each rotation of the third motor 701.

[0029] Next, the control cylinder 403 extends, driving the drill 405 to descend. The drill rod moves downward inside the casing 406 and drills a hole in the valve body. During the drilling process, water enters the casing 406 through the drain pipe 407 and is sprayed onto the drill rod, which cools the drill rod on one hand and mixes with the dust generated during drilling on the other.

[0030] Once one valve body is drilled, the rotating mechanism 7 controls the column 5 to rotate, which in turn drives the bearing plate 8 to rotate, allowing the valve bodies to reach the bottom of the drill rod one by one. The drilling mechanism then drills holes in each valve body individually, eliminating the need for frequent valve body replacements and improving drilling efficiency.

[0031] In addition, this embodiment also requires the configuration of an air pump, control valve, and air supply pipeline to provide power for the operation of the cylinder.

[0032] Example 2 The bottom of the support plate 8, near the center block, has multiple drainage holes 10; the upper end of the column 5 has a water collection basin 11, and the center of the column 5 has a water passage hole 12. The base 1 has a drainage channel 13. The drainage holes 10, water collection basin 11, water passage hole 12, and drainage channel 13 are connected, and the outer end of the drainage channel 13 is connected to a flange. The flange allows connection to external pipes, which are used to connect to wastewater treatment equipment. Wastewater from the drilling process falls into the support plate 8, preventing wastewater from flowing around and reducing pollution. Water in the support plate 8 enters the water collection basin 11 through the drainage holes 10, then enters the drainage channel 13 through the water passage hole 12, and finally exits through the drainage channel 13.

[0033] Sealing rings 14 are provided on both sides of the drive cavity of the column 5. The sealing rings 14 prevent water from entering the drive cavity 6, thereby preventing the rotating mechanism 7 from getting damp or damaged.
