Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a numerical control milling machine for mold processing. Background Art

[0002] As one of the important equipment for mold processing, the numerical control milling machine realizes precise control of the machine tool through a computer numerical control system (CNC), and can complete mold processing tasks with complex shapes and high-precision requirements. After clamping and fixing the mold, the tool above is driven to perform operations such as cutting and grinding.

[0003] There are still some deficiencies in the clamping of the existing equipment for molds. It can only clamp the mold singly. When it is necessary to process other surfaces of the mold, it is necessary to release the fixation, adjust and then clamp and process again, which is rather inconvenient. There are also those who directly rotate the entire clamping component for convenient adjustment to achieve the adjustment effect, but there are still areas for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies in the prior art that it can only clamp the mold singly. When it is necessary to process other surfaces of the mold, it is necessary to release the fixation, adjust and then clamp and process again, which is rather inconvenient, and to propose a numerical control milling machine for mold processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A numerical control milling machine for mold processing, comprising a milling machine main body;

[0007] A clamping component for clamping the mold. The clamping component is arranged on the workbench of the milling machine main body. The clamping component includes a base and a clamping piece. The base is installed on the top of the workbench. The clamping piece is located on one inner wall of the base. The clamping piece includes a clamping circular plate, a limiting circular plate and a plurality of clamping plates. A cylinder is fixedly arranged on one inner wall of the base, and the limiting circular plate is rotatably sleeved on the outer wall of the cylinder. A plurality of sliding grooves are formed on one side of the clamping circular plate, and one ends of the plurality of clamping plates are respectively slidably arranged inside the plurality of sliding grooves.

[0008] In a possible design, a plurality of arc-shaped limiting grooves are formed on one side of the limiting circular plate close to the clamping circular plate. A plurality of through holes are formed on one side of the clamping circular plate close to the limiting circular plate, and the plurality of through holes are respectively communicated with the plurality of sliding grooves. A limiting rod is fixedly arranged on one side end of the clamping plate close to the through hole, and one end of the limiting rod extends to the outside through the through hole. The plurality of limiting rods are respectively matched with the plurality of arc-shaped limiting grooves.

[0009] In a possible design, the clamping assembly further includes a connecting plate and a limiting plate. The connecting plate is fixedly arranged on the outer wall of the clamping circular plate. An L-shaped plate is fixedly arranged on the outer wall of the limiting circular plate. A sliding rod is fixedly arranged on one inner wall of the L-shaped plate, and the limiting plate is slidably sleeved on the outer wall of the sliding rod. A first triangular block is fixedly arranged on one side of the connecting plate, and a second triangular block is fixedly arranged on one side of the limiting plate, and the inclined surfaces of the first triangular block and the second triangular block are matched with each other.

[0010] In a possible design, an annular tooth groove is formed on one inner wall of the base close to the limiting circular plate, and the limiting circular plate is located inside the annular tooth groove. One end of the limiting plate is matched with the annular tooth groove.

[0011] In a possible design, a compression spring is sleeved on the outer wall of the sliding rod, and both ends of the compression spring are respectively fixedly arranged on one inner wall of the L-shaped plate and one side of the limiting plate.

[0012] In a possible design, a motor is fixedly arranged on one side of the base away from the limiting circular plate. One end of the output shaft of the motor penetrates through the cylinder and is fixedly arranged on one side of the clamping circular plate.

[0013] In this application, during specific use, after the mold is held and placed between multiple clamping plates, the driving motor drives the clamping circular plate to rotate. At this time, the limiting plate on the outer wall of the limiting circular plate is engaged with the annular tooth groove, so that the limiting circular plate cannot rotate. When the clamping circular plate rotates, the limiting rods at one ends of the multiple clamping plates will be displaced under the influence of the arc-shaped limiting groove, so that when the clamping circular plate rotates, the multiple clamping plates will gradually move inward to achieve the clamping effect. And during the clamping process, the connecting plate on the outer wall of the clamping circular plate will approach the limiting plate on the outer wall of the limiting circular plate. When the inclined surface of the first triangular block touches the inclined surface of the second triangular block, the limiting plate will be gradually squeezed to displace away from the annular tooth groove, so that one end of the limiting plate disengages from the annular tooth groove, achieving the effect of releasing the fixation of the limiting circular plate after clamping the mold. Then when the other surface of the mold needs to be processed, continue to drive the motor to drive the clamping circular plate to rotate. At this time, the clamping circular plate will push the limiting plate through the connecting plate to drive the limiting circular plate to rotate together to achieve the adjustment effect. When it is necessary to release the clamping of the mold, only need to drive the limiting circular plate in the reverse direction, so that the first triangular block no longer fits with the second triangular block, and the limiting plate is reset under the force of the compression spring, so as to engage one end of the limiting plate with the annular tooth groove to complete the fixation of the limiting circular plate. Then when the clamping circular plate rotates, it will be affected by the arc-shaped limiting groove to expand the multiple clamping plates to release the clamping effect.

[0014] In the present utility model, for the numerical control milling machine used for mold processing, through the clamping assembly, after placing the mold between multiple clamping plates, the positive driving motor can drive the multiple clamping plates to clamp the mold. When it is necessary to process other surfaces of the mold during processing, only by continuously driving the motor to rotate forward can the mold be driven to rotate to achieve the adjustment effect;

[0015] In the present utility model, for the numerical control milling machine used for mold processing, through the clamping assembly, when it is necessary to release the clamping of the mold, only by rotating the reverse driving motor can the multiple clamping plates be driven to expand and release the clamping of the mold;

[0016] In the present utility model, during use, the clamping assembly is fixedly installed on the workbench of the milling machine main body. After placing the mold between multiple clamping plates, by rotating the driving motor, the multiple clamping plates can be moved inward towards the axis center to achieve clamping;

[0017] When it is necessary to adjust the mold for processing other surfaces, only by continuously rotating the driving motor can it be achieved. When releasing the clamping, only the reverse driving motor is needed, achieving integration of clamping and adjustment, which is more convenient for actual operation.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0024] Example 1

[0025] Reference Figure 1 , a numerically controlled milling machine, which is used in the field of mold processing, includes: a milling machine main body 1 and a clamping assembly 2. The milling machine main body 1 serves as the support and operation foundation of the entire equipment, and is provided with a workbench thereon for carrying and fixing the mold to be processed.

[0026] Reference Figure 3 , the clamping assembly 2 is installed on the top of the workbench, including a base 3 and a series of clamping members. The base 3 is installed on the workbench, and a cylinder 19 is fixed on one side of its interior for supporting and guiding the rotation of the limit circular plate 5. The limit circular plate 5 is in close fit with the cylinder 19 through its outer wall.

[0027] Reference Figure 3-4 , the core of the clamping member consists of a clamping circular plate 4, a limit circular plate 5 and a plurality of clamping plates 17. A plurality of sliding grooves 16 are formed on the clamping circular plate 4, and a clamping plate 17 is slidably installed in each sliding groove 16. These clamping plates 17 can clamp or loosen the mold during the sliding process. In addition, a plurality of through holes 7 are provided on one side of the clamping circular plate 4. These through holes 7 are communicated with the sliding grooves 16 for the limiting rod 20 to pass through. The limiting rod 20 is fixed on the clamping plate 17. After one end thereof passes through the through hole 7, it cooperates with the arc-shaped limiting groove 18 on the limit circular plate 5. By rotating the limit circular plate 5, the sliding range of the clamping plate 17 is controlled to ensure that the mold is clamped.

[0028] This application can be used in the field of mold processing and also in other fields applicable to this application.

[0029] Example 2

[0030] Reference Figure 2-4 , on the basis of Example 1, an improvement is made: a numerically controlled milling machine for mold processing, which is applied to the field of mold processing. In order to be able to rotate the mold during processing so as to process other surfaces, the clamping assembly 2 is also designed with structures such as a connecting plate 13, a limiting plate 9, an L-shaped plate 11 and a sliding rod 10. The connecting plate 13 is fixed on the outer wall of the clamping circular plate 4, while the L-shaped plate 11 is fixed on the outer wall of the limit circular plate 5. The sliding rod 10 is fixedly arranged on one side of the L-shaped plate 11, and the limiting plate 9 is slidably sleeved on the outer wall of the sliding rod 10. At the same time, a first triangular block 14 and a second triangular block 15 are respectively fixedly arranged on one side of the connecting plate 13 and the limiting plate 9, and the inclined surfaces of the two triangular blocks cooperate with each other. In addition, the annular tooth groove 8 formed inside the base 3 cooperates with one end of the limiting plate 9. A motor 6 is fixed on one side of the base 3. The output shaft of the motor 6 penetrates through the cylinder 19 and is fixedly connected with one side of the clamping circular plate 4. Through the drive of the motor, the rotational movement of the clamping circular plate 4 is realized.

[0031] Specifically, after the mold is held and placed between multiple clamping plates 17, the driving motor 6 drives the clamping circular plate 4 to rotate. At this time, the limiting plate 9 on the outer wall of the limiting circular plate 5 is engaged with the annular tooth groove 8, so that the limiting circular plate 5 cannot rotate. When the clamping circular plate 4 rotates, the limiting rods 20 at one end of the multiple clamping plates 17 will be displaced under the influence of the arc-shaped limiting groove 18, so that when the clamping circular plate 4 rotates, the multiple clamping plates 17 will gradually move inward to achieve the clamping effect. And during the clamping process, the connecting plate 13 on the outer wall of the clamping circular plate 4 will approach the limiting plate 9 on the outer wall of the limiting circular plate 5. When the inclined surface of the first triangular block 14 touches the inclined surface of the second triangular block 15, it will gradually squeeze the limiting plate 9 to displace toward the side away from the annular tooth groove 8, so that one end of the limiting plate 9 is disengaged from the annular tooth groove 8, achieving the effect of releasing the fixation of the limiting circular plate 5 after clamping the mold. After that, when the other surface of the mold needs to be processed, continue to drive the motor 6 to drive the clamping circular plate 4 to rotate. At this time, the clamping circular plate 4 will push the limiting plate 9 through the connecting plate 13 to drive the limiting circular plate 5 to rotate together to achieve the adjustment effect. The limiting circular plate 5 has a certain friction force through itself or by adding other rings on the inner wall to prevent the limiting circular plate 5 from rotating by itself. When it is necessary to release the clamping of the mold, just drive the limiting circular plate 5 in the reverse direction so that the first triangular block 14 no longer fits with the second triangular block 15, and the limiting plate 9 is reset under the force of the compression spring 12, so that one end of the limiting plate 9 is engaged with the annular tooth groove 8 to complete the fixation of the limiting circular plate 5. After that, when the clamping circular plate 4 rotates, it will be affected by the arc-shaped limiting groove 18 to expand the multiple clamping plates 17 to release the clamping effect, achieving the integration of clamping and adjustment, which is more convenient for actual operation.

[0032] As is well known to those skilled in the art, the working principles and wiring methods of the milling machine main body 1 and the motor 6 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.
