Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool processing technology, specifically a multi-angle adjustment fixture for CNC machine tools. Background Technology

[0002] Traditional CNC machine tool fixtures are devices used to fix and position workpieces in CNC machining. Their core function is to ensure that the workpiece maintains a stable geometric position during machining to withstand external forces such as cutting forces and vibrations. However, in order to clamp and fix cylindrical workpieces during machine tool machining, it is particularly important to develop a multi-angle adjustable fixture for CNC machine tools.

[0003] A fixture for CNC machine tools with convenient angle adjustment, as described in reference announcement number CN216359428U, includes two clamping blocks arranged opposite each other. Each clamping block is fixedly connected to a lead screw nut. A lead screw is inserted inside the lead screw nut and installed inside a rotary table. A driven bevel gear is mounted in the middle of the lead screw, meshing with a driving bevel gear. The driving bevel gear is mounted on the output shaft of a first motor. The first motor is fixed to the side of the rotary table and installed inside a support cylinder seat, which is coaxially arranged... The machine tool consists of a cylinder and a circular plate. A connecting sleeve and a slewing bearing are fitted around the outside of the cylinder. A second motor is installed between the outer wall of the cylinder and the inner wall of the connecting sleeve. This CNC machine tool uses a fixture with an adjustable angle, which can be flexibly adjusted according to requirements. It can clamp the workpiece in both the vertical and horizontal directions. As can be seen from the above, although the fixture can be used well, it is usually not convenient to lock the clamping parts after adjustment, making it difficult for the fixture to achieve the expected stability, which needs to be improved.

A first strip plate is fixedly installed on the inner wall of the lower end of the first side connecting plate. The first side connecting plate is provided to facilitate the placement of the first strip plate.

[0007] Preferably, a second strip plate is provided on the inner wall of the second side connecting plate near the first side connecting plate. The top of both the second strip plate and the first strip plate are fixedly installed with clamping frames. The arrangement of the second strip plate and the first strip plate is used to arrange the clamping frames.

[0008] Preferably, a columnar workpiece is installed on the inner side of the clamping frame, and a lower clamp is provided at the bottom of the clamping frame. The inner wall of the lower clamp contacts the bottom end of the columnar workpiece. The lower clamp is provided to cooperate with the upper clamp to clamp and position the columnar workpiece.

[0009] Preferably, an upper clamp is slidably connected to the upper end of the clamping frame, and the inner wall of the upper clamp contacts the top of the cylindrical workpiece. The upper clamp is designed to cooperate with the lower clamp to clamp and position the cylindrical workpiece.

[0010] Preferably, a screw is threadedly installed at the top of the clamping frame, the bottom end of the screw is rotatably connected to the top of the upper clamp, and a rotating handle is installed at the top of the screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the multi-angle adjustable fixture for CNC machine tools not only ensures the stability of the machine tool fixture during use, but also improves the convenience of using the machine tool fixture, and achieves the purpose of easy clamping and positioning of cylindrical workpieces;

[0012] (1) By turning the nut seat, the nut seat rotates and slides inside the locking bolt, so that one end of the nut seat is screwed into a corresponding threaded hole. The second side plate can be locked by the disc to reduce the phenomenon of flipping and moving during the processing of the columnar workpiece, thereby ensuring the stability of the machine tool fixture during use.

[0013] (2) The second side connecting plate is driven by the geared motor to rotate slowly, so that the second side connecting plate drives the columnar workpiece to rotate slowly through the second strip plate, and drives the shaft to rotate in the bearing seat through the first side connecting plate, so as to flip the columnar workpiece according to the processing requirements, thereby making it easier to process the columnar workpiece from multiple angles, thus improving the convenience of using the machine tool fixture.

[0014] (3) By placing the two ends of the columnar workpiece on the top of the lower chuck, and then rotating the handle, the drive screw is rotated at the top of the clamping frame and slides down, so that the screw drives the upper chuck to slide down the inner wall of the clamping frame and contact the top of the columnar workpiece, so that the upper chuck cooperates with the lower chuck to perform clamping operation on the columnar workpiece, thereby achieving the purpose of easy clamping and positioning of the columnar workpiece.

[0022] In use, the first side connecting plate 7 is provided to facilitate the placement of the first strip plate 8;

[0023] A second strip plate 11 is provided on the inner wall of the second side connecting plate 10 near the first side connecting plate 7. The top of the second strip plate 11 and the first strip plate 8 are both fixedly installed with a clamping frame 16.

[0024] In use, the second strip plate 11 and the first strip plate 8 are set together to accommodate the clamping frame 16.

[0025] A columnar workpiece 15 is installed on the inner side of the clamping frame 16, and a lower clamp 17 is provided at the bottom of the clamping frame 16. The inner wall of the lower clamp 17 contacts the bottom end of the columnar workpiece 15.

[0026] In use, the lower chuck 17 is set up to cooperate with the upper chuck 18 to clamp and position the cylindrical workpiece 15.

[0027] The upper end of the clamping frame 16 is slidably connected to the upper clamp 18, and the inner wall of the upper clamp 18 contacts the top of the columnar workpiece 15.

[0028] In use, the upper chuck 18 is set up to cooperate with the lower chuck 17 to clamp and position the cylindrical workpiece 15.

[0029] A screw 19 is threaded onto the top of the clamping frame 16, and the bottom end of the screw 19 is rotatably connected to the top of the upper clamp 18. A handle 20 is installed on the top of the screw 19.

[0030] In use, the screw 19 is driven to rotate and slide up and down at the top of the clamping frame 16 by rotating the handle 20.

[0031] Another support frame 2 has a second bearing seat 5 at its top. A geared motor 9 is installed at the top of the second bearing seat 5. One end of the geared motor 9 passes through the second bearing seat 5 and is connected to a second side connecting plate 10. A disc 12 is provided on the outer wall of the second side connecting plate 10. Several threaded holes 13 are provided at the edge of the outer wall of the disc 12. A vertical rod 14 is provided at the bottom of the second bearing seat 5 on one side of the geared motor 9. A limit frame 21 is installed on the outer wall of the vertical rod 14.

The upper chuck 18, in conjunction with the lower chuck 17, clamps the cylindrical workpiece 15. The maximum length of the cylindrical workpiece 15 is slightly greater than the distance between the two clamping frames 16 to meet the clamping requirements of the fixture. If the length of the cylindrical workpiece 15 is short, one end of the cylindrical workpiece 15 can be clamped by the clamping component above the second strip plate 11. Then, the second side connecting plate 10 is driven by the reduction motor 9 to rotate slowly, so that the second side connecting plate 10 drives the columnar workpiece 15 to rotate slowly via the second strip plate 11, and drives the shaft 6 to rotate in the bearing seat via the first side connecting plate 7, so as to flip the columnar workpiece 15 according to the processing requirements, so that the columnar workpiece 15 can be processed from multiple angles. Finally, by turning the nut seat 22, the nut seat 22 rotates and slides inside the locking bolt 23, so that one end of the nut seat 22 is screwed into a corresponding threaded hole 13, and the second side connecting plate 10 is locked by the disc 12, so as to reduce the phenomenon of flipping and moving the columnar workpiece 15 during processing, thereby completing the use of the machine tool fixture.
