[0028] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0030] As shown in the figure, a cutting and positioning device for mechanical parts includes a frame 1, a cutting mechanism and a positioning mechanism. The positioning mechanism is rotatably arranged on the frame 1. The cutting mechanism includes a support frame 2 symmetrically arranged on the frame 1 and a beam 3 arranged between the support frames 2. A cutting component is slidably arranged on the beam 3.

[0031] The cutting assembly includes a telescopic cylinder 4 and a cutting head 5 arranged at the piston end of the telescopic cylinder 4. The telescopic cylinder 4 is electrically connected to a solenoid valve. A housing 6 is fixedly arranged outside the telescopic cylinder 4. A linear motor 7 is fixedly arranged on the inner wall of the rear side of the housing 6. The linear motor 7 is slidably connected to the crossbeam 3 through a first slider 8. A slide rail 9 cooperating with the first slider 8 is arranged on the side wall of the crossbeam 3. The first slider 8 can be a large-load slider with a large bearing capacity to improve the mechanical strength.

[0032] The front end of the telescopic cylinder 4 is fixedly connected to the inner wall of the housing 6 through the cylinder seat 10, the linear motor 7 is fixedly connected to the top of the cylinder seat 10 through the U-shaped fastener 11, and the other end of the cylinder seat 10 is slidably connected to the crossbeam 3 through the limit slider 12. A limit slide 13 that cooperates with the limit slider 12 is provided on the other side wall of the crossbeam 3.

[0033] When in use, the linear motor 7 is started, and its forward and reverse rotation drives the telescopic cylinder 4 and the housing 6 to move back and forth along the beam 3, thereby realizing the lateral movement of the cutting head 5; the piston end of the telescopic cylinder 4 is extended and retracted to realize the longitudinal movement of the cutting head 5 to adapt to the processing of mechanical parts of different sizes and shapes.

[0034] The positioning mechanism includes a rotating disk 14 and an operating table 15 disposed on the rotating disk 14. A rotating motor 16 is disposed inside the frame 1. The output shaft of the rotating motor 16 passes through the frame 1 and is fixedly connected to the rotating disk 14. The rotating motor 16 can be a stepping motor. When the rotating motor 16 is started, the rotating disk 14 rotates a certain angle on the frame 1 to realize the rotation of the positioning mechanism, so as to adapt to the processing and cutting of mechanical parts at different positions.

[0035] The operating table 15 is fixedly connected to the rotating disk 14 through a switch-type magnetic seat 17. The operating table 15 is generally made of a steel structure. When the switch is turned on, the switch-type magnetic seat 17 is magnetically attracted to the operating table. When the switch is turned off, the magnetic force disappears, and the operating table 15 can be easily removed from the rotating disk 14 to adapt to different rotating disks 14 (cutting machine tools), with strong adaptability.

A bearing platform 26 is arranged between the first positioning fixture and the second positioning fixture. The bearing platform 26 is an inverted U-shaped structure for bearing mechanical parts to be processed.

[0037] The first positioning fixture includes a support seat 18 and a support plate 19 perpendicular to the support seat 18. A number of evenly arranged flexible clamp heads 20 are provided on the support plate 19. The flexible clamp heads 20 are usually made of elastic materials, such as rubber, silicone or polyurethane, to avoid damage to the mechanical parts to be processed. Compared with the traditional hard clamp head, the flexible clamp head 20 has higher flexibility and adaptability, and can adapt to mechanical parts of different shapes and sizes. It should be noted that the flexible clamp head 20 in this application is a prior art, and its specific working principle and structure will not be described in detail here.

[0038] A screw rod 21 is provided through the support seat 18, and two threaded sections with opposite rotation directions are provided on the screw rod 21. An adjusting wheel 22 is fixedly provided at one end of the screw rod 21, and a fastening sleeve 23 is fixedly provided at the other end of the screw rod 21. A second slider 24 is provided at the bottom end of each support seat 18, and a slide groove 25 cooperating with the second slider 24 is provided on the operating table 15. When the adjusting wheel 22 is rotated forward, the first positioning fixture and the second positioning fixture move toward each other until the flexible fixture head 20 is completely in contact with the mechanical parts to be cut and produces the maximum deformation, and the clamping and positioning is completed; on the contrary, when the adjusting wheel 22 is rotated in the reverse direction, the first positioning fixture and the second positioning fixture move in opposite directions, and the mechanical parts can be removed.

[0039] A controller 27 is disposed on the outer wall of the support frame 2 . The controller 27 is electrically connected to the solenoid valve, the linear motor 7 , and the rotary motor 16 . The controller 27 controls the start and stop of each component.

[0040] When the device is used, first, the position of the operating table 15 on the rotating disk 14 is adjusted according to the cutting requirements. After the position is determined, the switch of the switch-type magnetic seat 17 is turned on, and the operating table 15 is magnetically fixed on the rotating disk 14; the mechanical parts to be cut are placed on the supporting platform 26 to wait for cutting, and the adjusting wheel 22 is rotated forward, and the first positioning fixture and the second positioning fixture are close to each other to firmly clamp the mechanical parts to be processed. The second slider 24 cooperates with the slide groove 25 to ensure that the first positioning fixture and the second positioning fixture do not deviate when moving, and the clamping force is uniform.

[0041] The linear motor 7 is started, and its forward and reverse rotation drives the telescopic cylinder 4 and the housing 6 to move back and forth along the beam 3, thereby realizing the lateral movement of the cutting head 5; the piston end of the telescopic cylinder 4 is extended and retracted, thereby realizing the longitudinal movement of the cutting head 5, and processing mechanical parts of different sizes and shapes; the rotary motor 16 is started to drive the positioning mechanism to rotate, thereby realizing the rotary cutting of mechanical parts, and after the cutting is completed, the adjusting wheel 22 is rotated in the opposite direction, the flexible clamp head 20 is released, and the cut mechanical parts can be removed.

[0042] Therefore, the utility model adopts the above-mentioned mechanical parts cutting and positioning device, which can adapt to the processing of mechanical parts of different sizes and shapes, and can also be adapted to different rotating disks (cutting machine tools); the flexible clamp head can not only adapt to mechanical parts of different shapes and sizes, but also avoid damage to the mechanical parts to be processed and improve the processing accuracy; it reduces the complicated process of disassembling and repositioning mechanical parts, and has high work efficiency and strong practicality.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
