Description

Technical Field

[0001] The invention relates to the technical field of workpiece numerical control processing equipment, and in particular to workpiece numerical control processing equipment with an adaptive leveling compensation structure. Background Art

[0002] Workpiece CNC machining equipment is an automated equipment used for precision machining of various materials such as metal, plastic, wood, etc. These equipment can achieve high-precision and high-efficiency machining by accurately controlling the machining process through a computer numerical control system. For example, when machining wood workpieces, the leveling compensation structure on the machining equipment can monitor the position changes of the wood workpiece in real time through built-in sensors and control systems, and automatically adjust as needed to ensure machining accuracy.

[0003] After searching, the Chinese patent "Workpiece clamping device for CNC machining equipment with dust suction function" authorization announcement number "CN220463055U" realizes the adjustment of the height of the connecting plate and the extrusion plate through limit screws and movable plates, thereby achieving clamping of workpieces of different heights to ensure the accuracy of workpiece processing.

[0004] The heights of the two sets of connecting plates and the extrusion plates are adjusted by rotating a plurality of limit screws, and the two sets of connecting plates need to be debugged several times to be at the same height, which makes clamping the workpiece inconvenient.

[0005] Therefore, a workpiece CNC machining device with an adaptive leveling compensation structure is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a workpiece CNC machining device with an adaptive leveling compensation structure in order to solve the above-mentioned problem, thereby improving the problem of excessive invariance in clamping the workpiece.

[0007] The present invention realizes the above object through the following technical solutions. A numerically controlled machining equipment for workpieces with an adaptive leveling compensation structure includes: a numerically controlled machine tool, and clamping plates are arranged on both sides inside the numerically controlled machine tool; an adjustment mechanism is arranged inside the numerically controlled machine tool; wherein, the adjustment mechanism includes a leveling plate arranged inside the numerically controlled machine tool, the lower end of the surface of the clamping plate is slidably connected to the inner wall of the leveling plate, a first electric push rod is fixedly connected to the bottom of the leveling plate, the telescopic end of the first electric push rod is fixedly connected to a connecting plate, indirect plates are slidably connected to both sides of the surface of the connecting plate, the surface of the indirect plate is slidably connected to the inner wall of the clamping plate, a liquid storage tank is fixedly connected to the inner wall of the indirect plate, and a pressing plate frame is slidably connected to the inner wall of the liquid storage tank. Through the first electric push rod, the connecting plate and the indirect plate, the heights of the two pressing plate frames are adjusted to the same height simultaneously and quickly pressed against the top of the wood workpiece. The operation of clamping the wood workpiece is simple. Through the leveling plate and the pressing plate frame, the wood workpiece is flattened, ensuring the flatness of clamping the wood workpiece and ensuring the practicability of the numerically controlled machining equipment.

[0008] Preferably, a bidirectional lead screw is rotatably connected to the inner wall of the leveling plate, the lower end of the surface of the clamping plate is threadedly connected to the surface of the bidirectional lead screw, a servo motor is fixedly connected to one side of the leveling plate, the output shaft of the servo motor is fixedly connected to one end of the bidirectional lead screw, a transition box is fixedly connected to the top of the clamping plate, a piston block is slidably connected to the inner wall of the transition box, a hose is fixedly connected to the relative ends of the transition box and the liquid storage tank, and hydraulic oil is filled in both the transition box and the liquid storage tank. Through the hydraulic oil in the liquid storage tank and the transition box, the pressing plate frame flexibly presses the wood workpiece, reducing the damage to the wood workpiece during clamping and avoiding the situation of over-pressing the wood workpiece, resulting in uneven wood surface.

[0009] Preferably, an elastic ball is fixedly connected to the top end of the piston block, and the elastic ball is a nitrile rubber component.

[0010] Preferably, a first spring is fixedly connected to the relative end of the transition box and the piston block.

[0011] Preferably, a second spring is fixedly connected to the relative end of the liquid storage tank and the pressing plate frame. Through the first spring and the second spring, the indirect plate and the pressing plate frame move upward. The elastic force of the second spring pulls the pressing plate frame downward, and the elastic force of the first spring pushes the piston block downward, ensuring that part of the hydraulic oil in the transition box flows back to the liquid storage tank, and further ensuring that the pressing plate frame can flexibly press the wood workpiece next time.

[0012] Preferably, a magnifying glass is fixedly connected to the top end of the transition box. Through the magnifying glass, the deformation process of the elastic ball is magnified, enabling the staff to clearly observe the appropriate height of the piston block moving upward, and then timely turning off the power supply of the first electric push rod to avoid the pressing plate frame over-pressing the top of the wood workpiece.

[0013] Preferably, a limiting block is fixedly connected to the surface of the indirect plate, and one side of the limiting block contacts one side of the clamping plate. Through the limiting block, it is ensured that the clamping plate can drive the indirect plate to move along during movement, ensuring the consistency of the positions of the clamping plate and the indirect plate.

[0014] Preferably, the hose is a polyurethane component.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. Through the first electric push rod, the connecting plate and the indirect plate, the heights of the two sets of pressing plate frames are adjusted to the same height simultaneously and quickly pressed against the top of the wood workpiece. The operation of clamping the wood workpiece is simple. Through the flattening plate and the pressing plate frame, the wood workpiece is flattened, ensuring the flatness of clamping the wood workpiece and the practicability of the numerical control processing equipment. Through the hydraulic oil in the liquid storage tank and the transition tank, the pressing plate frame flexibly presses the wood workpiece, reducing the damage to the wood workpiece during clamping and avoiding the situation of over-pressing the wood workpiece, resulting in uneven wood surface;

[0017] 2. Through the first spring and the second spring, the indirect plate and the pressing plate frame move upward. The elastic force of the second spring pulls the pressing plate frame downward, and the elastic force of the first spring pushes the piston block downward, ensuring that part of the hydraulic oil in the transition tank flows back to the liquid storage tank, thereby ensuring that the pressing plate frame can flexibly press the wood workpiece next time;

[0018] 3. Through the magnifying glass, the process of elastic spherical deformation is magnified, enabling the staff to clearly observe the appropriate height of the upward movement of the piston block, and then timely turning off the power supply of the first electric push rod to avoid over-pressing the top of the wood workpiece by the pressing plate frame.

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] During specific implementation: As Figures 1-4 shown, a workpiece numerical control processing device with an adaptive leveling compensation structure includes: a CNC machine tool 1, and clamping plates 4 are provided on both sides inside the CNC machine tool 1; an adjustment mechanism 5, and the adjustment mechanism 5 is provided inside the CNC machine tool 1; wherein, the adjustment mechanism 5 includes a leveling plate 51 provided inside the CNC machine tool 1, the lower end surface of the clamping plate 4 is slidably connected to the inner wall of the leveling plate 51, the bottom of the leveling plate 51 is fixedly connected with a first electric push rod 56, the telescopic end of the first electric push rod 56 is fixedly connected with a connecting plate 55, both sides of the surface of the connecting plate 55 are slidably connected with intermediate plates 52, the surface of the intermediate plate 52 is slidably connected to the inner wall of the clamping plate 4, a liquid storage tank 53 is fixedly connected to the inner wall of the intermediate plate 52, and a pressure plate frame 54 is slidably connected to the inner wall of the liquid storage tank 53.

[0026] Second electric push rods are fixedly connected to both sides of the bottom of the leveling plate 51, the bottom ends of the second electric push rods are fixedly connected to the inner bottom wall of the CNC machine tool 1, and a laser rangefinder is fixedly connected to the inner wall of the CNC machine tool 1.

[0027] When it is necessary to process a wood workpiece, open the observation door on the numerical control machine tool 1, place the wood workpiece on the top of the leveling plate 51, drive the two clamping plates 4 to approach each other and contact both sides of the wood workpiece. The movement of the clamping plate 4 drives the indirect plate 52 to move on the surface of the connecting plate 55. Manually activate the first electric push rod 56. The telescopic end of the first electric push rod 56 moves downward, driving the connecting plate 55 to move downward. The downward movement of the connecting plate 55 drives the indirect plate 52 and the pressing plate frame 54 to move downward, causing the pressing plate frame 54 to abut against the wood workpiece. Manually turn off the first electric push rod 56 to level and clamp the wood workpiece. At this time, by operating the console on the numerical control machine tool 1, the cutting tool inside the numerical control machine tool 1 processes the wood workpiece and the laser rangefinder is turned on to monitor the height of the wood workpiece. When the height of the wood workpiece is lower than the appropriate distance from the cutting tool, the second electric push rod is automatically activated. The telescopic end of the second electric push rod moves upward, driving the leveling plate 51 to move upward to an appropriate position, and then manually turn off the second electric push rod to ensure that the wood workpiece and the cutting tool are at an appropriate height for precise processing of the wood workpiece. At this time, the cutting tool continues to operate.

[0028] As Figure 4 shown, a bidirectional lead screw 3 is rotatably connected to the inner wall of the leveling plate 51. The lower end of the surface of the clamping plate 4 is threadedly connected to the surface of the bidirectional lead screw 3. One side of the leveling plate 51 is fixedly connected with a servo motor 2. The output shaft of the servo motor 2 is fixedly connected to one end of the bidirectional lead screw 3. The top of the clamping plate 4 is fixedly connected with a transition box 58. A piston block 59 is slidably connected to the inner wall of the transition box 58. A hose 57 is fixedly connected to the opposite ends of the transition box 58 and the liquid storage tank 53. The interiors of the transition box 58 and the liquid storage tank 53 are both filled with hydraulic oil. A first spring 511 is fixedly connected to the opposite ends of the transition box 58 and the piston block 59. A second spring 512 is fixedly connected to the opposite ends of the liquid storage tank 53 and the pressing plate frame 54. The hose 57 is a polyurethane member.

[0029] The polyurethane member hose 57 is elastic, which can ensure that the hose 57 can deform. Both the pressing plate frame 54 and the piston block 59 are rubber members. The upper end of the surface of the pressing plate frame 54 is in close contact with the liquid storage tank 53 to prevent hydraulic oil from leaking to the bottom of the pressing plate frame 54. The lower end of the surface of the piston block 59 is in close contact with the transition box 58 to prevent hydraulic oil from leaking to the top of the piston block 59.

[0030] Manually turn on the servo motor 2. The output shaft of the servo motor 2 rotates to drive the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 drives the two clamping plates 4 to approach each other and contact both sides of the wood workpiece, initially positioning the wood workpiece on the leveling plate 51. Manually turn off the servo motor 2 and turn on the first electric push rod 56. The telescopic end of the first electric push rod 56 moves downward to drive the connecting plate 55 to move downward. The downward movement of the connecting plate 55 drives the intermediate plate 52 and the pressure plate frame 54 to move downward, causing the pressure plate frame 54 to abut against the wood workpiece. At this time, the first electric push rod 56 continues to drive the connecting plate 55 and the intermediate plate 52 to move downward, causing the pressure plate frame 54 to move in the liquid storage tank 53 and stretch the second spring 512, so that the hydraulic oil in the liquid storage tank 53 flows through the hose 57 into the transition tank 58. Excessive hydraulic oil in the transition tank 58 pushes the piston block 59 to move upward by an appropriate height. Manually turn off the first electric push rod 56, so that the pressure plate frame 54 presses the wood workpiece flexibly and evenly, quickly and conveniently leveling and clamping the wood workpiece.

[0031] As Figure 2 and Figure 4 shown, the top end of the piston block 59 is fixedly connected with an elastic ball 510. The elastic ball 510 is a nitrile rubber component. The top end of the transition tank 58 is fixedly connected with a magnifying glass 514.

[0032] After the wood workpiece is processed, manually turn off the cutting tool and turn on the first electric push rod 56. The telescopic end of the first electric push rod 56 moves upward to drive the connecting plate 55, the intermediate plate 52 and the pressure plate frame 54 to move upward by an appropriate height, so that the bottom of the pressure plate frame 54 is far away from the wood workpiece. Manually turn off the first electric push rod 56. The elastic force of the second spring 512 pulls the pressure plate frame 54 to move downward, and the elastic force of the first spring 511 pushes the piston block 59 to move downward, ensuring that part of the hydraulic oil in the transition tank 58 flows back into the liquid storage tank 53, thereby ensuring that the pressure plate frame 54 can flexibly press the wood workpiece next time. The elastic ball 510 is far away from the bottom end of the transition tank 58. The elastic ball 510 made of nitrile rubber component has good elasticity, so that the elastic ball 510 resets when there is no external force against it, so as to observe the deformation of the elastic ball 510 next time. At this time, take the processed wood workpiece on the top of the leveling plate 51.

[0033] As Figure 4 shown, a limiting block 513 is fixedly connected to the surface of the intermediate plate 52. One side of the limiting block 513 contacts one side of the clamping plate 4. The movement of the clamping plate 4 can drive the intermediate plate 52 to move through the limiting block 513.

[0034] When the present invention is in use, open the observation door on the numerical control machine tool 1, place the wood workpiece on the top of the leveling plate 51, manually start the servo motor 2, the output shaft of the servo motor 2 rotates to drive the bidirectional lead screw 3 to rotate, the bidirectional lead screw 3 rotates to drive the two clamping plates 4 to approach each other and contact both sides of the wood workpiece, manually turn off the servo motor 2 and start the first electric push rod 56, the telescopic end of the first electric push rod 56 moves downward to drive the connecting plate 55 to move downward, the connecting plate 55 moves downward to drive the intermediate plate 52 and the pressure plate frame 54 to move downward simultaneously, so that the pressure plate frame 54 abuts against the wood workpiece. At this time, the first electric push rod 56 continues to drive the connecting plate 55 and the intermediate plate 52 to move downward, so that the pressure plate frame 54 moves in the liquid storage tank 53 and stretches the second spring 512, so that the hydraulic oil in the liquid storage tank 53 flows into the transition tank 58 through the hose 57. Excessive hydraulic oil in the transition tank 58 pushes the piston block 59 upward, so that the first spring 511 is compressed. The piston block 59 moves upward to drive the elastic ball 510 to move upward and abut against the bottom end of the transition tank 58. Because the elastic ball 510 is a nitrile rubber component, the elastic ball 510 has good elasticity. The elastic ball 510 will deform when moving upward and abutting against the transition tank 58. The appropriate height of the upward movement of the piston block 59 and the deformation of the elastic ball 510 can be clearly observed through the magnifying glass 514. At this time, manually turn off the first electric push rod 56, so that the pressure plate frame 54 flexibly presses against the wood workpiece, quickly and conveniently leveling and clamping the wood workpiece. At this time, by operating the console on the numerical control machine tool 1, the cutting tool in the numerical control machine tool 1 processes the wood workpiece and the laser rangefinder monitors the height of the wood workpiece. When the height of the wood workpiece is lower than the appropriate distance from the cutting tool, the second electric push rod is automatically started. The telescopic end of the second electric push rod moves upward to drive the leveling plate 51 to move upward to an appropriate position, and then manually turn off the second electric push rod to ensure that the wood workpiece and the cutting tool are at an appropriate height for precise processing of the wood workpiece. At this time, the cutting tool continues to operate. After the wood workpiece is processed, by operating the console on the numerical control machine tool 1, the power supplies of the cutting tool and the laser rangefinder are turned off, and under the action of the first electric push rod 56 and the servo motor 2, the clamping of the wood workpiece is released, and then the wood workpiece can be taken.

[0035] It should be noted that in the above description, the numerical control machine tool 1, the servo motor 2, the first electric push rod 56, the laser rangefinder, the second electric push rod, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supplies of the numerical control machine tool 1, the servo motor 2, the first electric push rod 56, the laser rangefinder, and the second electric push rod can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
