Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a CNC lathe machine with an adjustable clamp. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] The existing fixed mold holders on CNC lathes are inconvenient when clamping workpieces of different sizes, as the clamps are difficult to adapt to workpieces of different sizes for fixing.

[0004] For example, the patent with authorization announcement number CN210305807U discloses a CNC lathe with an adjustable clamping seat; this adjustable clamping seat can automatically change the position of the clamping block according to the size of the mold, and change the clamping position of the clamping block according to the requirements of the mold. The clamping block can either support the mold outward or clamp the mold inward, which can adapt to different mold shapes.

[0005] However, after the clamping blocks of this device clamp the mold, when locking it, they need to be locked into the sliding rail on the telescopic seat by bolts on each clamping block. The three clamping blocks are locked by bolts, which is not only cumbersome to operate and affects work efficiency, but also makes it difficult to ensure that the mold is in the center of the adjustable clamping seat when locking, affecting practicality. Therefore, a CNC lathe with an adjustable clamping seat is designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a CNC lathe machine with an adjustable clamp.

[0007] The technical problem to be solved by this utility model is to provide a CNC lathe with an adjustable clamp to solve the problems of existing CNC lathes with adjustable clamps.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A CNC lathe with an adjustable clamping seat includes a worktable and a slide. The slide is embedded in the upper surface of the worktable, and a tool assembly is slidably disposed in the slide. A bracket is fixedly disposed on the upper surface of the worktable, and a second motor is fixedly installed below the left side surface of the bracket. An adjustable clamping seat is installed at the output end of the second motor.

[0010] The adjusting clamp includes a clamping plate, a through groove, a guide rod, a clamping block, and a connecting rod. A through groove is formed on the outer surface of the clamping plate. A guide rod is fixedly installed in the through groove, and a clamping block is slidably installed in the through groove. A connecting rod is installed in the center of the inner surface of the clamping plate. The connecting rod is installed on the output end of the second motor, and a drive component is installed on the connecting rod to drive the clamping block to move simultaneously and to position the clamping block.

[0011] Preferably, there are three through slots, and the included angle between two adjacent through slots is 120°, so that the three clamping blocks 903 in the through slot 901 can clamp the workpiece from three directions respectively, ensuring stability.

[0012] Preferably, the outer end of the clamping block extends out of the through groove, and the inner end of the clamping block is on the same vertical plane as the inner surface of the clamping disk, ensuring the stability of the clamping block.

[0013] Preferably, the drive assembly includes a collar sleeved on a connecting rod, and multiple connecting rods are rotatably mounted on the outer surface of the collar via three inverted concave brackets. The other ends of the multiple connecting rods are respectively mounted on the inner surface of the clamping block via pins, and locking bolts are threaded to the side of the collar.

[0014] Preferably, the portion of the clamping block extending out of the through groove has an outwardly curved arc shape on one side of the clamping disc, which increases the contact area between the clamping block and the workpiece, increases friction, and ensures stability.

[0015] Preferably, the inner and outer surfaces of the portion of the clamping block extending out of the through groove are fixedly provided with rubber layers to increase the friction between the clamping block and the workpiece and ensure stability.

[0016] Preferably, the end of the locking bolt is provided with an internal hexagonal nut, and the other end of the locking bolt is fixedly provided with a frosted rubber layer. When the locking bolt is tightened, it is in close contact with the outer surface of the connecting rod, which increases the friction between the locking bolt and the surface of the connecting rod and ensures the stability of the position of the locking bolt after it is locked to the collar.

[0017] Preferably, the tool assembly includes a lead screw threaded to the upper right surface of the worktable, a slider rotatably mounted on the left end of the lead screw via a bearing, the slider sliding within a groove, a first motor fixedly mounted on the upper surface of the slider, a tool mounted on the output end of the first motor, and a rotating wheel fixedly mounted on the right end of the lead screw.

[0018] Preferably, a scrap collection hopper is provided on the left side of the upper surface of the workbench, and a drawer slot is provided through the bottom of the scrap collection hopper. A drawer is slidably provided in the drawer slot to facilitate the collection of scrap generated during processing.

[0019] Preferably, the scrap collection hopper is located directly below the adjusting clamp, and the drawer slot is located directly below the scrap collection hopper, so that the scrap in the scrap collection hopper can fall into the drawer slot.

[0020] Compared with the prior art, this utility model has at least the following beneficial effects:

[0021] In the above solution, by setting an adjustable clamping seat and a driving assembly, when clamping a workpiece, the rod-shaped workpiece is inserted between three clamping blocks, and the collar slides along the connecting rod away from the clamping plate. The collar drives the three clamping blocks to move simultaneously towards the center of the clamping plate via a connecting rod, thus clamping the workpiece. The position of the collar is fixed by tightening the locking bolt, achieving the effect of positioning the clamping blocks and ensuring the stability of the clamping blocks in clamping the workpiece. This solution is suitable for clamping and fixing rod-shaped workpieces of different diameters, and the simultaneous movement of the three clamping blocks ensures that the workpiece is in the center of the clamping plate. When fixing a tubular workpiece, the tubular workpiece is sleeved on the three clamping blocks, and the collar moves along the connecting rod towards the side closer to the clamping plate. The collar drives the three clamping blocks to move simultaneously away from the center of the clamping plate via a connecting rod, thus clamping and fixing the tubular workpiece. This solution is also suitable for fixing tubular workpieces of different diameters, increasing practicality.

[0022] In the above solution, by setting up a scrap metal collection hopper, the metal scraps generated during processing fall into the scrap metal collection hopper and then into the drawer in the drawer slot, thus achieving the effect of collecting the scrap metal. When the scrap metal needs to be disposed of, simply pull out the drawer from the drawer slot to dispose of the scrap metal in the drawer. Attached Figure Description

[0034] like Figures 1-5 As shown, an embodiment of the present invention provides a CNC lathe with an adjustable clamp, including a worktable 1 and a slide 2. The slide 2 is embedded in the upper surface of the worktable 1, and a tool assembly is slidably arranged in the slide 2. A bracket 7 is fixedly arranged on the upper surface of the worktable 1, and a second motor 8 is fixedly installed below the left side surface of the bracket 7. An adjustable clamp is installed at the output end of the second motor 8.

[0035] The adjusting clamp includes a clamping plate 9, a through groove 901, a guide rod 902, a clamping block 903, and a connecting rod 904. A through groove 901 is opened on the outer surface of the clamping plate 9. The guide rod 902 is fixedly installed in the through groove 901. The clamping block 903 is slidably installed in the through groove 901. A connecting rod 904 is installed in the center of the inner surface of the clamping plate 9. The connecting rod 904 is installed on the output end of the second motor 8. A drive component is installed on the connecting rod 904 to drive the clamping block 903 to move simultaneously and to position the clamping block 903.

[0036] In this embodiment, three through slots 901 are provided, and the included angle between two adjacent through slots 901 is 120°, which facilitates the three clamping blocks 903 in the through slots 901 to clamp the workpiece from three directions, thus ensuring stability.

[0037] In this embodiment, the outer end of the clamping block 903 extends out of the through groove 901, and the inner end of the clamping block 903 is on the same vertical plane as the inner surface of the clamping disk 9.

[0038] In this embodiment, the drive assembly includes a collar 905 sleeved on the connecting rod 904. Multiple connecting rods 906 are rotatably arranged on the outer surface of the collar 905 through three inverted concave brackets. The other ends of the multiple connecting rods 906 are respectively set on the inner surface of the clamping block 903 through pins. Locking bolts 907 are threadedly connected to the side of the collar 905.

[0039] By incorporating an adjustable clamping base and a drive assembly, when clamping a workpiece, the rod-shaped workpiece is inserted between three clamping blocks. A collar 905 slides along the connecting rod 904 away from the clamping disc 9. The collar 905, via a connecting rod 906, drives the three clamping blocks 903 to move simultaneously towards the center of the clamping disc 9, thus clamping the workpiece. The position of the collar 905 is then fixed by tightening the locking bolts 907, achieving the positioning effect of the clamping blocks 903 and ensuring the stability of the workpiece clamping. This mechanism is suitable for various applications. This device can clamp and fix rod-shaped workpieces of different diameters. The simultaneous movement of the three clamping blocks 903 ensures that the workpiece is in the center of the clamping plate. When fixing tubular workpieces, the tubular workpiece is sleeved on the three clamping blocks 903, and the collar 905 moves along the connecting rod 904 towards the side closer to the clamping plate 9. The collar 905 drives the three clamping blocks 903 to move simultaneously away from the center of the clamping plate 9 via the connecting rod 906. The three clamping blocks 903 clamp and fix the tubular workpiece, and it is suitable for fixing tubular workpieces of different diameters, increasing its practicality.

[0040] In this embodiment, the part of the clamping block 903 extending out of the through groove 901 has an outward curved arc shape on one side of the clamping plate 9, which increases the contact area between the clamping block 903 and the workpiece, increases friction, and ensures stability.

[0041] In this embodiment, the inner and outer surfaces of the part of the clamping block 903 extending out of the through groove 901 are fixedly provided with rubber layers 9031 to increase the friction between the clamping block 903 and the workpiece and ensure stability.

[0042] In this embodiment, the end of the locking bolt 907 is provided with an internal hexagonal nut, and the other end of the locking bolt 907 is fixedly provided with a frosted rubber layer. When the locking bolt 907 is locked, it is in close contact with the outer surface of the connecting rod 904, which increases the friction between the locking bolt 907 and the surface of the connecting rod 904, and ensures the stability of the position of the locking bolt 907 after locking the collar 905.

[0043] In this embodiment, the tool assembly includes a lead screw 3 threadedly connected to the upper right surface of the worktable 1. A slider 4 is rotatably mounted on the left end of the lead screw 3 via a bearing, and the slider 4 slides in the groove 2. A first motor 5 is fixedly mounted on the upper surface of the slider 4. A tool 6 is mounted on the output end of the first motor 5. A rotating wheel is fixedly mounted on the right end of the lead screw 3.

[0044] When processing the workpiece held on the clamping plate 9, the rotating wheel can be rotated, which drives the lead screw 3 to rotate. The lead screw 3 drives the slider 4 and the first motor 5 to move to the right. The first motor 5 drives the tool 6 to rotate, and the tool 6 can process the workpiece held on the clamping plate 9.

[0045] In this embodiment, a scrap collection hopper 10 is provided on the left side of the upper surface of the workbench 1, and a drawer slot 11 is provided through the bottom of the scrap collection hopper 10, and a drawer 12 is slidably provided in the drawer slot 11.

[0046] In this embodiment, the scrap collection hopper 10 is located directly below the adjusting clamp, and the drawer slot 11 is located directly below the scrap collection hopper 10.

[0047] By setting up a scrap collection hopper 10, the metal scraps generated during processing fall into the scrap collection hopper 10 and then into the drawer 12 in the drawer slot 11, thus achieving the effect of collecting scraps. When scraps need to be disposed of, simply pull out the drawer 12 from the drawer slot 11 to dispose of the scraps in the drawer 12.
