[0043] Below, combined with the attached Figure 1-5 As well as specific implementation methods, the present application is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0044] This embodiment discloses a motorcycle frame metal cutting device.

[0045] See also Figure 1A motorcycle frame metal cutting device includes a cutting table 1 and a cutting head 2. A processing position 14 and a processing position 13 are provided on the cutting table 1. The cutting head 2 is located above the processing position 13. At the same time, a pair of clamping seats 16 are provided on the processing position 14 and the processing position 13. The clamping seat 16 is connected to the cutting table 1 by a bolt 160. Specifically, two positioning hole groups are provided on the cutting table 1, one positioning hole group is located at the processing position 13, and the other positioning hole group is located at the processing position 14. Each positioning hole group includes a plurality of positioning holes 15, and the plurality of positioning holes 15 extend along the length direction of the cutting table 1. In this way, after the clamping seat 16 is placed at different positioning holes 15 and the bolt 160 is screwed into the positioning hole 15, the position of the clamping seat 16 can be adjusted and fixed, so that the distance between the pair of clamping seats 16 is adjustable. Each pair of clamping seats 16 clamps a workpiece, and the two workpieces are in the same placement state. The clamping seats 16 can be three-jaw chucks, which are convenient for loading and unloading the workpieces, thereby increasing the speed of moving the workpieces from the processing position 14 to the processing position 13.

[0046] See also Figure 1 and Figure 2 A pair of slide rails 12 are also provided on the cutting table 1. The pair of slide rails 12 also extend along the length direction of the cutting table 1 and are in the same extension direction as the plurality of positioning holes 15 in the positioning hole group. The pair of slide rails 12 are located at the position to be processed 14 and are separated from the corresponding clamping seat 16. A base 11 is adaptively provided on the pair of slide rails 12. The base 11 is L-shaped. The horizontal end of the base 11 is clamped on the slide rail 12 and can slide on the slide rail 12. The sliding direction of the base 11 is the X direction. A driving mechanism 3 and an adjusting mechanism 4 are provided between the base 11 and the cutting head 2. The driving mechanism 3 is used to drive the cutting head 2 to move along the Y direction or the Z direction. The driving mechanism 3 includes a first linear driving unit 31, a second linear driving unit 32 and an extension rod 33. The first linear driving unit 31 and the second linear driving unit 32 are connected by the extension rod 33. The cutting head 2 is arranged on the second linear driving unit 32. The second linear driving unit 32 drives the cutting head 2 to move along the Y direction. The first linear driving unit 31 is used to drive the first linear driving unit 31, the extension rod 33 and the cutting head 2 to move along the Z direction. The adjusting mechanism 4 includes a sleeve 41, a pressure rod 42, a spring 43 and a pressure sensor 44. The sleeve 41 is connected to the extension rod 33 and is located above the workpiece in the processing position 14. The pressure sensor 44 is fixed on the inner side of the sleeve 41. One end of the pressure rod 42 is passed through the inner side of the sleeve 41, and the other end of the pressure rod 42 is located below the sleeve 41. The spring 43 is arranged between one end of the pressure rod 42 and the pressure sensor 44. The other end of the pressure rod 42 is provided with a pressure ball 45. The pressure ball 45 is in contact with the top of the workpiece in the processing position 14 and the spring 43 is in a compressed state.

[0047] The adjusting mechanism 4 contacts the top of the workpiece at the processing position 14, and the adjusting mechanism 4 can adjust the displacement of the cutting head 2 in the Z direction by the driving mechanism 3. Specifically, when the workpiece is clamped on the pair of clamping seats 16 corresponding to the processing position 13 and the workpiece is clamped on the pair of clamping seats 16 corresponding to the processing position 14, the controller controls the first linear driving unit 31 to move, so that the extension rod 33 moves along the Z direction. When the pressure ball 45 contacts the workpiece on the processing position 14, as the extension rod 33 continues to move downward, the spring 43 will be in a compressed state. In this way, the elastic force generated by the compression of the spring 43 will act on the pressure sensor 44, so that the pressure value collected by the pressure sensor 44 gradually increases. When the pressure value reaches the preset range, the controller will control the first linear driving unit 31 to stop moving. At this time, the distance between the cutting head 2 and the workpiece at the processing position 13 is in an optimal state. When the initial position of the cutting head 2 is positioned, the base 11 can be pushed to achieve linear cutting of the workpiece in the X direction. When the flatness of the workpiece is poor, the pressure head can maintain a state of being in contact with the workpiece under the action of the elastic force of the spring 43, so that the pressure value collected by the pressure sensor 44 will change. At this time, through the driving action of the first linear drive mechanism 3 on the extension rod 33, the compression state of the spring 43 is maintained in a relatively constant state, so that the distance between the cutting head 2 and the workpiece can be maintained in an optimal state, thereby improving the cutting effect of the cutting head 2 on the workpiece. Furthermore, the second linear drive mechanism 3 can drive the cutting head 2 to move along the Y direction, so that linear cutting of the workpiece in the Y direction is achieved.

[0048] See also Figure 3 and Figure 4The first linear drive unit 31 includes a vertical rod 311, a first driving block 312 and a first screw rod 313. The vertical rod 311 is detachably arranged at the vertical end of the base 11. The first screw rod 313 extends along the axial direction of the vertical rod 311. A first support plate 314 is provided on the top of the vertical rod 311. The vertical plate is provided with a first guide rail 3111 toward the direction of the extension rod 33. The first guide rail 3111 is adaptively provided with a first slider 3112. The first driving block 312 is fixed on the first slider 3112. One end of the first screw rod 313 is penetrated on the first support plate 314 and the other end is penetrated on the horizontal end of the base 11. A first motor 315 for driving the first screw rod 313 to rotate is provided on the first support plate 314. A threaded sleeve 3120 is penetrated in the middle of the first driving block 312, and the threaded sleeve 3120 is adaptively sleeved on the first screw rod 313. Since the first screw rod 313 and the threaded sleeve 3120 are threadedly connected, and the first driving block 312 cannot rotate circumferentially under the limiting action of the first slider 3112, when the first motor 315 drives the first screw rod 313 to rotate, the first driving block 312 can reliably move along the Z direction, and the extension rod 33 is connected to the first driving block 312. Driven by the first driving block 312, the extension rod 33 can reliably move along the Z direction. Since the adjustment mechanism 4 is arranged on the extension rod 33, the length of the pressure rod 42 inserted into the sleeve 41 can be reliably controlled through the movement of the extension rod 33, thereby controlling the elastic force of the spring 43, so that the pressure value transmitted to the control by the pressure sensor 44 can be kept relatively constant.

[0049] See also Figure 3 and Figure 5The second linear drive unit 32 includes a crossbar 321, a second drive block 322 and a second screw rod 323. One end of the extension rod 33 is connected to the first drive block 312, and the other end of the extension rod 33 is connected to the crossbar 321. A second support plate 324 is provided at the end of the crossbar 321. One end of the second screw rod 323 is penetrated on the second drive block 322, and the other end is penetrated on the second support plate 324. A second motor 325 for driving the second screw rod 323 to rotate is provided on the second support plate 324. A second guide rail 3211 is provided at the bottom of the crossbar 321, and a second slider 3212 is adaptively provided on the second guide rail 3211. The second drive block 322 is connected to the second slider 3212. A first guide rail 3111 is provided on the outer wall of the vertical rod 311, and a first slider 3112 is adaptively provided on the first guide rail 3111. The first drive block 312 is connected to the first slider 3112. Since the second driving block 322 is connected to the second slider 3212 on the second guide rail 3211, the second driving block 322 cannot rotate circumferentially. In this way, when the second motor 325 drives the second screw rod 323 to rotate, the second slider 3212 can drive the second driving block 322 to slide reliably on the second guide rail 3211, thereby enabling the cutting head 2 to complete the Y-direction linear cutting of the workpiece.

[0050] See also Figure 3 A first bearing 3130 for fixing the first screw rod 313 is provided on the horizontal end of the base 11 and the first support plate 314, and a second bearing 3230 for fixing the second screw rod 323 is provided on the second driving block 322 and the second support plate 324. The first screw rod 313 can rotate between the two first bearings 3130, and the second screw rod 323 can rotate between the two second bearings 3230. Under the action of the first bearing 3130 and the second bearing 3230, the first screw rod 313 and the second screw rod 323 can rotate reliably, thereby ensuring that the cutting head 2 can be reliably driven in the Z direction and the Y direction. The end of the extension rod 33 close to the second screw rod 323 is provided with a third vertical plate 331 and a third bearing 332. The third vertical plate 331 is provided with a third motor 333. The output shaft of the third motor 333 is provided with a third screw rod 334. The third screw rod 334 passes through the third bearing 332 and is connected to the top of the cross bar 321. The third motor 333 is used to drive the third screw rod 334 to rotate, and the cross bar 321 can rotate around the axis of the third screw rod 334. Since the third screw rod 334 and the cross bar 321 are fixedly connected, when the third motor 333 drives the third screw rod 334 to rotate, the cross bar 321 can rotate around the axis of the third screw rod 334. When the cutting head 2 and the third screw rod 334 are in a misaligned state, the cutting head 2 can form a circumferential cutting of the workpiece when rotating, such as cutting a hole in the workpiece. The cutting function is more comprehensive, and the cutting and hole cutting of the workpiece can be completed at the same time without other equipment.

[0051] When the present application is in use, the height of the cutting head 2 is adjusted in real time by the change of the effect of the spring 43 on the pressure sensor 44. In this way, when the surface flatness of the workpiece is poor, the distance between the cutting head 2 and the workpiece can always be maintained at the optimal distance, thereby effectively improving the cutting effect of the workpiece. Furthermore, by driving the base 11, the workpiece can be cut linearly in the X direction, and by driving the cutting head 2 by the second motor 325, the workpiece can be cut linearly in the Y direction. By driving the cutting head 2 by the second motor 325 and the third motor 333, a hole of a specified size can be cut on the surface of the workpiece, which expands the use scenario of the equipment and effectively improves the cutting efficiency.

[0052] This embodiment also provides a method for intelligent processing of a motorcycle frame.

[0053] A motorcycle frame intelligent processing method, applied to a motorcycle frame metal cutting device, comprises the following steps:

[0054] S1, placing a workpiece on a pair of clamping seats 16 at the processing position 14, and placing another identical workpiece on a pair of clamping seats 16 at the processing position 13, and the two workpieces are in the same placement state;

[0055] S2, the first motor 315 drives the first screw rod 313 to rotate, so that the first driving block 312 can drive the extension rod 33 and the adjustment mechanism 4 to move downward, so that the spring 43 in the adjustment mechanism 4 is in a compressed state. At this time, the pressure sensor 44 can collect the pressure value and transmit the pressure value to the controller. When the pressure value reaches the preset range value, the controller controls the first motor 315 to stop rotating. At this time, the distance between the cutting head 2 and the workpiece on the processing position 13 is the optimal distance;

[0056] S3, pushing the base 11 to slide on the slide rail 12 to complete the linear cutting operation of the workpiece in the X direction;

[0057] S4, the second motor 325 drives the second screw rod 323 to rotate, completing the linear cutting operation of the workpiece in the Y direction;

[0058] S5. The third motor 333 drives the third screw rod 334 to rotate, completing the circular cutting operation of the workpiece in the horizontal direction.

[0059] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
