Description

Technical Field

[0001] The utility model relates to the field of CNC milling machines, in particular to a CNC milling machine with a fixture that can be adjusted at multiple angles. Background Technique

[0002] A CNC milling machine is an automatic processing device developed on the basis of a general milling machine. It can perform a variety of processing operations and has powerful functions. Before using the CNC milling machine to process a workpiece, it is necessary to first clamp and fix the workpiece with a fixture, and then carry out the next step of processing; due to the different shapes, sizes and lengths of workpieces, it is necessary to frequently replace the fixture and select a fixture with a suitable specification to clamp the workpiece. Frequent disassembly and replacement of the fixture not only takes time and effort, seriously affects the processing efficiency, but also causes wear of the fixture and affects the service life of the fixture.

[0003] The existing Chinese patent (publication number: CN218254053U) discloses a fixture that is convenient for adjusting the angle. When the motor is started, the fixed plate can be rotated, and the rotation of the fixed plate realizes the adjustment of the clamping angle of the fixture, so that the workpiece can be clamped and fixed from different directions, thereby greatly improving the flexibility of the fixture. When the hydraulic rod is started, it can drive the threaded plate to move, so that the fixed plate can be turned over, and the fixed plate can turn over the workpiece, thereby further improving the practicability of the fixture.

[0004] However, the fixture that is convenient for adjusting the angle designed above still has some disadvantages in actual use; due to the adjustable angle of the fixture that is convenient for adjusting the angle, the fixed plate is relatively high from the operating table. When processing some workpieces with a relatively small volume, the workpiece will be in a suspended state after being clamped stably. For some drilling and polishing processes, the stability is poor, and problems such as shaking and deviation are likely to occur.

[0005] Therefore, it is necessary to provide a CNC milling machine with a fixture that can be adjusted at multiple angles to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides a CNC milling machine with a fixture that can be adjusted at multiple angles.

[0007] A numerically controlled milling machine with a fixture that can be adjusted at multiple angles provided by the present utility model includes: a base and cutting components connected to both sides of the top of the base. A bottom plate is fixedly installed on the top of the base. Connecting components are fixedly installed on both sides of the bottom plate. A clamping component is fixedly installed on the connecting component. First sliding grooves are opened on both sides of the bottom plate. A bidirectional screw is rotatably connected inside the first sliding groove. One end of the bottom plate is fixedly connected to a driving motor. The driving shaft of the driving motor is fixedly connected to the bidirectional screw. Sliders are threadedly sleeved at both ends of the bidirectional screw. A connecting rod is rotatably connected to the side of the slider away from the bidirectional screw. A lifting plate is movably connected to the top of the bottom plate. The other end of the connecting rod is rotatably connected to one side of the lifting plate.

[0008] Preferably, the clamping component includes a cylinder. The cylinder is fixedly installed on the top of the connecting component. The driving end of the cylinder is fixedly connected to a telescopic plate. The telescopic plate is movably connected to the connecting component through the cylinder.

[0009] Preferably, it further includes an adjusting component. The adjusting component includes two first mounting seats. The two first mounting seats are respectively fixedly installed on the top and bottom of the telescopic plate. An electric push rod is rotatably connected to the first mounting seat. One end of the clamping plate is fixedly connected to a second mounting seat. The second mounting seat is rotatably connected to the driving end of the electric push rod.

[0010] Preferably, a second sliding groove is opened on the side of the telescopic plate away from the connecting component. A connecting block is fixedly connected to the side of the clamping plate close to the second sliding groove. A rotating shaft is arranged in the second sliding groove. The connecting block is rotatably connected to the telescopic plate through the rotating shaft.

[0011] Preferably, first pin shafts and second pin shafts are arranged in both the second mounting seat and the first mounting seat. Both ends of the electric push rod are respectively rotatably sleeved on the first pin shaft and the second pin shaft.

[0013] Compared with the related art, a numerically controlled milling machine with a fixture that can be adjusted at multiple angles provided by the present utility model has the following beneficial effects:

Detailed Embodiment

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Please refer to Figures 1 to 4 , a numerically controlled milling machine with a fixture that can be adjusted at multiple angles includes: a base 1 and a cutting assembly 2 connected to both sides of the top of the base 1. A bottom plate 3 is fixedly installed on the top of the base 1. Connecting pieces 4 are fixedly installed on both sides of the bottom plate 3. A clamping assembly is fixedly installed on the connecting pieces 4. First chutes 10 are provided on both sides of the bottom plate 3. A bidirectional screw 7 is rotatably connected inside the first chutes 10. One end of the bottom plate 3 is fixedly connected to a driving motor 6. The driving shaft of the driving motor 6 is fixedly connected to the bidirectional screw 7. Sliders 8 are threadedly sleeved at both ends of the bidirectional screw 7. One side of the slider 8 away from the bidirectional screw 7 is rotatably connected to a connecting rod 9. A lifting plate 5 is movably connected to the top of the bottom plate 3. The other end of the connecting rod 9 is rotatably connected to one side of the lifting plate 5.

[0023] In the specific implementation process, the workpiece is placed on the top of the lifting plate 5. If the workpiece is small in volume and has a large distance from the clamping plate 15, the driving motor 6 can be started to rotate the bidirectional screw rod 7, so that the two sliders 8 on one side of the bottom plate 3 slide towards each other in the first chute 10 respectively. The approaching sliders 8 lift the lifting plate 5 through the connecting rod 9, facilitating the workpiece with a smaller volume to approach the clamping plate 15, so that it can be clamped by the clamping plate 15. And after the clamping is stable, it can play a supporting role for the workpiece, helping to solve the problem that the workpiece still shakes during processing, improving the stability, and also enhancing the working efficiency of the staff when clamping the workpiece, so as to facilitate the cutting assembly 2 to process the workpiece.

[0024] It should be noted that: The clamping assembly includes a cylinder 11. The cylinder 11 is fixedly installed on the top of the connecting piece 4. The driving end of the cylinder 11 is fixedly connected with a telescopic plate 12. The telescopic plate 12 is movably connected with the connecting piece 4 through the cylinder 11. One end of the telescopic plate 12 far from the cylinder 11 is movably connected with a clamping plate 15. The clamping plate 15 is made of deformable material.

[0025] After the workpiece is placed at an appropriate height, the cylinder 11 can be driven to drive the telescopic plate 12 to move, so that the clamping plate 15 moves horizontally. The clamping plates 15 are symmetrically arranged above the bottom plate 3, so as to clamp workpieces of different sizes. By controlling the telescopic movement of the clamping plate 15 through the cylinder 11, the clamping force and position of the clamping plate 15 on the workpiece can be ensured, avoiding machining errors caused by unstable clamping or inaccurate clamping position.

[0026] It should be noted that: It further includes an adjusting assembly. The adjusting assembly includes two first mounting seats 13. The two first mounting seats 13 are respectively fixedly installed on the top and bottom of the telescopic plate 12. An electric push rod 14 is rotatably connected to the first mounting seat 13. One end of the clamping plate 15 is fixedly connected with a second mounting seat 17. The second mounting seat 17 is rotatably connected to the driving end of the electric push rod 14.

[0027] If the shape of the edge of the workpiece is irregular, the electric push rod 14 can be driven to control the telescopic length of its driving end, so as to drive the second mounting seat 17 and the clamping plate 15 to adjust their positions, adjust the angle of the clamping plate 15, and enable the clamping plate 15 to rotate on the telescopic plate 12 through the connecting block 16. This operation facilitates the clamping plate 15 to fit the outer shape of the workpiece more closely, so as to further clamp the workpiece and improve the stability of the workpiece during processing.

[0028] It should be noted that: A second chute 18 is provided on the side of the telescopic plate 12 far from the connecting piece 4. A connecting block 16 is fixedly connected to the side of the clamping plate 15 close to the second chute 18. A rotating shaft is arranged in the second chute 18. The connecting block 16 is rotatably connected to the telescopic plate 12 through the rotating shaft.

[0029] By setting the rotating shaft, the clamping plate 15 can rotate around the rotating shaft within the second sliding groove 18 by a certain angle, facilitating the clamping plate 15 to adapt to workpieces with different shapes and processing requirements. When it is necessary to clamp inclined or irregular workpieces, it can provide more effective clamping support.

[0030] It should be noted that: both the second mounting seat 17 and the first mounting seat 13 are provided with a first pin shaft and a second pin shaft, and the two ends of the electric push rod 14 are respectively rotatably sleeved on the first pin shaft and the second pin shaft.

[0031] By setting the pin shaft, it is convenient for the electric push rod 14 to move, enabling the clamping plate 15 to flexibly adjust its position and angle to better adapt to workpieces with different shapes and processing requirements.

[0032] It should be noted that: a rubber pad is provided on one side of the clamping plate 15, and anti-slip patterns are provided on the outer surface of the rubber pad.

[0033] By setting the rubber pad and providing anti-slip patterns on its outer surface, the stability during clamping of the workpiece is increased.

[0034] The working principle of a numerically controlled milling machine with a fixture that can be adjusted at multiple angles provided by the present utility model is as follows:

[0035] When the device is in use, place the workpiece on the top of the lifting plate 5. If the workpiece is small in size and has a large distance from the clamping plate 15, the driving motor 6 can be started to rotate the bidirectional screw rod 7, causing the two sliders 8 on one side of the bottom plate 3 to slide towards each other within the first sliding groove 10. The approaching sliders 8 raise the lifting plate 5 through the connecting rod 9, facilitating the smaller-sized workpiece to approach the clamping plate 15, so that it can be clamped by the clamping plate 15. And after stable clamping, it can play a supporting role for the workpiece, helping to solve the problem of workpiece shaking during processing, improving stability, and also enhancing the working efficiency of the staff when clamping the workpiece, so as to facilitate the cutting assembly 2 to process the workpiece.

[0036] After the workpiece is placed at an appropriate height, the telescopic plate 12 can be driven by the cylinder 11 to move the clamping plate 15 in the horizontal direction to facilitate clamping workpieces of different sizes. If the edge shape of the workpiece is irregular, the angle of the clamping plate 15 can be adjusted by the symmetrically arranged electric push rods 14, enabling the clamping plate 15 to rotate on the telescopic plate 12 through the connecting block 16. This operation facilitates the clamping plate 15 to better fit the outer shape of the workpiece, so as to further clamp the workpiece and enhance the stability of the workpiece during processing.

[0037] The above are only embodiments of the present utility model, and do not thereby limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
