Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a double-sided chuck. Background Art

[0002] As an important equipment for batch cutting and processing of workpieces, laser cutting machines are widely used in the workpiece cutting industry. The clamping chuck, as an indispensable component of the laser cutting machine, plays an important role in fixing the position of the workpiece and improving the cutting accuracy. When using laser to cut workpieces, the laser head usually does not move axially relative to the workpiece. The workpiece needs to be clamped by the chuck, and at the same time, the axial movement relative to the laser head and the rotation relative to the laser head are realized to achieve the purpose of continuous processing and feeding. The chuck clamps the workpiece by connecting with the spindle to ensure that the workpiece can maintain the correct position under the irradiation of the laser beam, thereby ensuring the cutting accuracy.

[0003] The existing chuck is usually a single-sided chuck. Since the workpiece will vibrate during the cutting process, and the clamping force of the single-sided chuck is insufficient, the workpiece will shift during the cutting process, thereby affecting the processing accuracy of the workpiece.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A double-sided chuck includes a bearing seat, a clamping assembly and a rotating assembly. A main shaft is installed on the bearing seat, the clamping assembly is arranged on the main shaft, the rotating assembly is arranged on one side of the clamping assembly and is connected to the clamping assembly. The clamping assembly is driven to rotate by the rotating assembly. The clamping assembly includes a chuck, and a clamping jaw is arranged on the chuck. The clamping jaw is used to clamp and fix a workpiece.

[0007] By adopting the above device, the main shaft is connected to the bearing seat, and the bearing seat is used to provide stable support to ensure the overall stability of the equipment. The workpiece is clamped and fixed by the claws on the clamping assembly to ensure the stability of the workpiece during the cutting process, and the deviation of the workpiece due to vibration during the cutting process is reduced, which is beneficial to improving the cutting accuracy of the workpiece. The rotating assembly drives the clamping assembly to drive the workpiece to rotate at the same time, thereby realizing multi-angle cutting of the workpiece and improving the cutting efficiency.

[0008] As a further description of the above technical solution:

[0009] The chuck comprises a first chuck and a second chuck. The first chuck and the second chuck are both sleeved on the main shaft. The first chuck and the second chuck are arranged in a mirror-symmetrical manner with the main shaft as the center.

[0010] By adopting the above device, the first chuck and the second chuck clamp the workpiece at the same time, so that the clamping force of the chuck on the workpiece is evenly distributed on the surface of the workpiece, reducing the vibration of the workpiece caused by cutting, and improving the processing stability and accuracy. At the same time, the double chuck design can adapt to workpieces of different sizes or shapes, improving processing flexibility and adaptability.

[0011] As a further description of the above technical solution:

[0012] The clamping jaws are provided in plurality, and the chuck is provided with a first sliding groove, the number of the first sliding grooves corresponds to the number of the clamping jaws, and the clamping jaws are connected in the first sliding grooves.

[0013] The chuck is also provided with adjusting pieces, the number of which corresponds to the number of the clamping jaws, the adjusting pieces are connected to the clamping jaws, and the adjusting pieces are used to adjust the clamping strength of the clamping jaws.

[0014] By adopting the above device, the clamping jaws are slidably connected in the slide groove, and the clamping force of the clamping jaws can be adjusted by the adjusting member, so that the chuck can flexibly adapt to workpieces of different sizes and shapes, ensuring the matching of the clamping force with the characteristics of the workpiece, thereby improving the clamping stability and reliability of the equipment for the workpiece.

[0015] As a further description of the above technical solution:

[0016] The adjusting member comprises a limit block and a second slide groove, wherein the second slide groove is fixed on the chuck, the limit block is connected in the second slide groove, and the side wall of the clamping jaw is provided with a connecting block, and the end of the connecting block is in contact with the limit block.

[0017] By adopting the above-mentioned device, when the clamping jaw needs to be adjusted, the limit block is manually moved to drive the connecting block to move at the same time. Since one end of the connecting block is in contact with the limit block and the other end is fixedly connected to the clamping jaw, the clamping jaw is driven to move while the connecting block moves, so as to adjust the clamping force of the clamping jaw according to the shape of the workpiece to adapt to workpieces of different shapes and sizes.

[0018] As a further description of the above technical solution:

[0019] The limit block is provided with a fastener, and the fastener is used to limit the movement of the limit block.

[0020] By adopting the above device, after the limit block is moved to adjust the clamp to a suitable position, the position of the limit block needs to be fixed by fasteners to fix the clamp, which is helpful to reduce the problem of the workpiece stability being affected by the loose clamp during the cutting process.

Since the driven gear is coaxially arranged with the first chuck and the second chuck, the first chuck and the second chuck are driven to rotate by the driven gear to realize multi-angle rotation of the workpiece, which is convenient for all-round cutting of the workpiece and greatly improves the cutting efficiency of the workpiece.

[0027] This application has the following beneficial effects:

[0028] 1. In the present application, the spindle is connected to the bearing seat, which provides stable support to ensure the overall stability of the equipment.

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] Example:

[0039] A double-sided chuck, such as Figure 1-3 As shown, it includes a bearing seat 1, a clamping assembly 2 and a rotating assembly 3. Among them, a spindle 11 is installed on the bearing seat 1, and the bearing seat 1 provides stable support to ensure the overall stability of the equipment. The clamping assembly 2 includes a chuck 21, and the chuck 21 is divided into a first chuck 21a and a second chuck 21b. The first chuck 21a and the second chuck 21b are both sleeved on the spindle 11, and are mirror-symmetrically arranged with the spindle 11 as the center of gravity. The first chuck 21a and the second chuck 21b are used to clamp the workpiece at the same time, so that the clamping force of the chuck 21 on the workpiece is evenly distributed on the surface of the workpiece, reducing the vibration of the workpiece caused by cutting, and improving the processing stability and accuracy. In addition, the rotating assembly 3 is connected to the first chuck 21a and the second chuck 21b respectively, and the first chuck 21a and the second chuck 21b are driven to rotate by the rotating assembly 3 to achieve multi-angle cutting of the workpiece, thereby improving the cutting efficiency. Among them, in this embodiment, the spindle 11 is selected as a bearing.

[0040] like Figure 1As shown, in this embodiment, four clamping jaws 22 are arranged on the chuck 21, and the four clamping jaws 22 are symmetrically distributed up and down and left and right so as to clamp the workpiece from four directions. At the same time, a corresponding number of first slide grooves 211 are also arranged on the chuck 21, and the clamping jaws 22 are slidably connected in the first slide grooves 211. The workpiece is clamped and fixed by the clamping jaws 22, thereby ensuring the stability of the workpiece during the cutting process, reducing the displacement of the workpiece due to vibration during the cutting process, effectively improving the accuracy of the workpiece cutting, and thus improving the quality of the workpiece.

[0041] In addition, if Figure 4 As shown, in order to adjust the position of the jaws 22 to accommodate workpieces of different shapes and sizes, an adjusting member 23 is also provided on the chuck 21. The adjusting member 23 is located on one side of the jaws 22. The position of the jaws 22 and the clamping force are adjusted by the adjusting member 23 to ensure that the clamping force matches the characteristics of the workpiece, thereby improving the clamping stability and reliability of the equipment for the workpiece.

[0042] like Figure 4 As shown, in this embodiment, the adjusting member 23 includes a limit block 231 and a second slide groove 232. The second slide groove 232 is fixed on the chuck 21, and the limit block 231 is slidably connected in the second slide groove 232. In addition, a connecting block 24 is provided between the adjusting member 23 and the clamping jaw 22, one end of the connecting block 24 is fixedly connected to the side wall of the clamping jaw 22 close to the adjusting member 23 by a bolt, and the other end is abutted against the limit block 231. A fastener 231a is provided on the limit block 231, and the fastener 231a is threadedly connected to the limit block 231, and the sliding of the limit block 231 in the second slide groove 232 is limited by the fastener 231a. Among them, in this embodiment, the fastener 231a is selected as a bolt.

[0043] During operation, the position and clamping force of the clamping jaw 22 need to be adjusted according to the shape and size of the workpiece, and the limit block 231 is manually moved to drive the connecting block 24 to move at the same time. Since the connecting block 24 is fixedly connected to the clamping jaw 22, the clamping jaw 22 is driven to move while the connecting block 24 moves, and the clamping jaw 22 is adjusted to a suitable position. When the clamping jaw 22 is adjusted to a suitable position, the limit block 231 is fixed by the fastener 231a, and the clamping jaw 22 no longer moves, which is conducive to reducing the problem of the stability of the workpiece affected by the looseness of the clamping jaw 22 during the cutting process.

[0044] like Figure 5As shown, in this embodiment, the end of the clamping jaw 22 is rotatably connected to a contact roller 221. When the workpiece passes through the clamping jaw 22, there is rolling friction between the workpiece and the contact roller 221, which can reduce the friction force of the contact roller 221 on the workpiece, thereby reducing the wear of the workpiece, and at the same time will not cause damage to the contact roller 221, thereby extending the service life of the equipment. In addition, a spring telescopic rod 222 is also provided in the clamping jaw 22. When the workpiece is fixed, the spring telescopic rod 222 pops out and abuts against the surface of the contact roller 221, limiting the rotation of the contact roller 221, which can effectively reduce the shaking or deviation of the workpiece during the cutting process, and further improve the accuracy and stability of the workpiece cutting.

[0045] like Figure 2-3 As shown, in this embodiment, the rotary drive member includes a reduction motor 31, a driving gear 32 and a driven gear 33. Among them, the driving gear 32 is connected to the output shaft of the reduction motor 31, and the driven gear 33 is meshed with the driving gear 32. The driven gear 33 is sleeved on the main shaft 11 and fixedly connected to the main shaft 11, and is located between the first chuck 21a and the second chuck 21b. During operation, the reduction motor 31 drives the driving gear 32 to rotate, and the driving gear 32 then drives the driven gear 33 to rotate. Since the driven gear 33 is coaxially arranged with the first chuck 21a and the second chuck 21b, the first chuck 21a and the second chuck 21b are driven to rotate by the driven gear 33 to realize multi-angle rotation of the workpiece, which is convenient for all-round cutting of the workpiece, and greatly improves the cutting efficiency of the workpiece.

[0046] Working principle: When cutting the workpiece, the workpiece is fixed by the first chuck 21a and the second chuck 21b, and the workpiece passes through the middle of the main shaft 11. The jaws 22 clamp the workpiece from four directions and adjust the position of the jaws 22 according to the shape and size of the workpiece. The jaws 22 are moved by toggling the limit block 231 so that the jaws 22 are pressed against the surface of the workpiece to fix the workpiece, and then the limit block 231 is fixed by the fastener 231a to limit the movement of the limit block 231, thereby reducing the possibility of loosening of the jaws 22, increasing the clamping force of the jaws 22 on the workpiece, and increasing the stability of the workpiece.
