DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] Example:

[0021] Reference Figures 1 to 11 , a four-axis cutting machine head for a cutting machine, comprising an upper connecting frame 1, a mobile connecting seat 2, a lower connecting frame 3, an upper cutting assembly 4 and a lower cutting assembly 5, wherein the mobile connecting seat 2 is fixedly connected to the linear drive motors at horizontal positions on both sides of the frame of the cutting machine, the upper connecting frame 1 is mounted on the top of the mobile connecting seat 2, the lower connecting frame 3 is mounted on the bottom of the mobile connecting seat 2, the upper cutting assembly 4 is mounted on the upper connecting frame 1, and the lower cutting assembly 5 is mounted on the lower connecting frame 3; The upper cutting assembly 4 includes a first linear motor 401 fixedly connected to the upper connecting frame 1, an L-shaped connecting piece 402 is fixedly connected to the moving end of the first linear motor 401, and an upper cutting saw 403 is installed at the bottom of the L-shaped connecting piece 402; The lower cutting assembly 5 includes a second linear motor 501, on which a lower cutting saw 502 is mounted. The angles of the saw blades of the lower cutting saw 502 and the upper cutting saw 403 are vertically distributed, and the lower cutting saw 502 and the upper cutting saw 403 are distributed up and down.

[0022] The frame of the cutting machine needs to be different from the conventional frame. It is necessary to install a component for clamping the plate on the frame, such as a device similar to a tiger table, or use a clamp driven by electricity, or use a component that increases friction. There are many options for the component for clamping the plate, which is not limited to the above-mentioned components. However, it should be noted that the component for clamping the plate cannot exceed the frame of the frame, or the distance beyond the frame is small, so as not to hinder the work of the upper cutting saw 403 and the lower cutting saw 502. When the upper cutting component 4 and the lower cutting component 5 are working, that is, when cutting is required, the linear drive motors on both sides of the frame The upper connecting frame 1 and the lower cutting assembly 5 of the mobile connecting seat 2 need to be transported to the designated position through the connection with the mobile connecting seat 2, and the saw blade on the upper cutting saw 403 or the lower cutting saw 502 is rotated, and the lower cutting saw 502 or the upper cutting saw 403 first performs longitudinal or transverse cutting, that is, the existing drill bit rotation cutting is changed to saw blade cutting, and at the same time, after one of the upper cutting saw 403 or the lower cutting saw 502 completes the longitudinal or transverse cutting, the other immediately performs the cutting work perpendicular to it. Compared with the single saw blade operation, the double saw blade can quickly connect the cutting work in two directions, which can The advantage of being able to get very close to the drill bit when it is rotating and cutting, and being easy to change the angle, compared with cutting by rotating the drill bit, the saw blade can significantly improve the efficiency of cutting materials, and the double saw blades distributed in the upper and lower positions can allow the upper cutting saw 403 and the lower cutting saw 502 at the upper and lower positions to move in the cutting direction while the other one is moving in the cutting direction, so as to achieve the effect of quickly cutting in two directions, instead of using two sets of linear drive motors on the frame to drive the upper cutting saw 403 and the lower cutting saw 502 at the upper and lower positions to achieve the purpose of cutting in two directions at the same time, The plate is relatively large, and the plate is clamped at the edge. If two directions are cut at the same time, the vibration of the plate will increase the burden on the clamping assembly, and a stronger clamping assembly is needed. The requirements for the clamping assembly are higher, and this clamping assembly needs to spend a lot of time to fix each plate. At the same time, the cost of the clamping assembly itself will also increase significantly, and together with the additional linear drive motor, it will increase the cost. For small plates, dual linear drive motors can be used on both sides of the frame to drive the upper cutting saw 403 and the lower cutting saw 502 respectively, so as to perform simultaneous cutting in two directions.

[0023] Specifically, the lower connecting frame 3 includes a support frame 301 fixedly installed on the bottom of the lower connecting seat 202, a movable seat 302 is slidably installed in the support frame 301, the second linear motor 501 is fixedly installed on the movable seat 302, an L-shaped connecting piece 402 is fixedly connected between the lower cutting saw 502 and the second linear motor 501, the movable connecting seat 2 includes an upper connecting seat 201 fixedly installed on both sides of the bottom of the upper connecting frame 1 and a lower connecting seat 202 fixedly installed on both sides of the top of the support frame 301, the bottom of the upper connecting seat 201 is fixedly connected with a connecting frame 204, the connecting frame 204 is fixedly connected to the linear drive motor between the cutting machine frame, the bottom of the connecting frame 204 is fixedly connected with a slider 205, the top of the lower connecting seat 202 is fixedly connected with a connecting block 203, the slider 205 is slidably installed on the top of the connecting block 203, contact plates 207 are fixedly connected on both sides of the connecting block 203, and both sides of the slider 205 are threaded and movably connected with the first adjusting nut 206.

[0024] After the upper cutting saw 403 completes the transverse cutting, the lower cutting saw 502 immediately performs the longitudinal cutting, and vice versa. Since the center of the saw blade needs to be connected to the rotating shaft of the motor, the saw blade cannot be inserted into the plate in a half-shape for cutting, that is, the saw blade can only be inserted into the plate in a small part. Therefore, after the upper cutting saw 403 completes the transverse cutting or the lower cutting saw 502 completes the longitudinal cutting, a small slope will be formed at the end of the cutting. If the lower cutting saw 502 completes the cutting work after the upper cutting saw 403 completes the cutting work, or the upper cutting saw 403 is inserted into the lower cutting saw 502, the lower cutting saw 502 will be cut off. 02 If the cutting work is carried out immediately after the cutting work is completed, a small connection head will be formed at the intersection of the cutting in two directions, resulting in poor cutting quality. In order to ensure the cutting quality, it is necessary to adjust the first adjusting nut 206 on both sides of the slider 205 and the second adjusting nut 303 on both sides of the moving seat 302 in combination with the slope generated by the cutting depth and the thickness of the plate. For example, a thicker plate will form a longer uncut connection point at a fixed slope, and a thinner plate will form a shorter uncut point. Remove the first adjusting nut 206 from the slider 205. When the upper connecting seat 201 is rotated out for a longer distance, the first adjusting nut 206 will contact the contact plate 207 faster when the upper connecting seat 201 is driven by the linear drive motor, and the gap between the first adjusting nut 206 and the contact plate 207 can be regarded as the gap between the upper connecting frame 1 and the lower cutting assembly 5 when the mobile connecting seat 2 moves. This gap can be used to control the interval between the upper cutting saw 403 and the lower cutting saw 502 at the cutting intersection, thereby controlling the gap between the landing point of the lower cutting saw 502 and the upper cutting saw 403, so as to help the upper cutting saw 403 Alternatively, after the lower cutting saw 502 completes cutting, the lower cutting saw 502 or the upper cutting saw 403 can cut according to the slope generated by the cutting, thereby avoiding the situation where the cutting intersection points generated during cutting are not cut, thereby improving the cutting quality. Similarly, by adjusting the second adjusting nuts 303 on both sides of the movable seat 302, when the first linear motor 401 and the second linear motor 501 move synchronously, the gap between the second adjusting nuts 303 and the support frame 301 can change the interval between the upper cutting saw 403 and the lower cutting saw 502 in this direction.

[0025] It should be noted that the movement of the upper connecting seat 201 is driven by the linear drive motor. After the first adjusting nut 206 contacts the contact plate 207, the contact plate 207 is pushed to move the lower cutting assembly 5 therebelow.

[0026] Specifically, the top of the upper cutting saw 403 is fixedly connected to a rotation limiting disk 407, and the top of the rotation limiting disk 407 is fixedly connected to a magnet mounting frame 408 via a rotating rod. Two magnets are embedded and fixedly mounted on the magnet mounting frame 408. The upper cutting saw 403 is rotatably mounted on the L-shaped connecting member 402 via a rotating rod between the rotation limiting disk 407 and the magnet mounting frame 408.

[0027] Specifically, two electromagnets 409 are fixedly connected to the top of the L-shaped connecting member 402, and the two electromagnets 409 are vertically distributed. The electromagnets 409 limit the magnet mounting frame 408 to rotate only 90°. The bottom of the rotation limiting disk 407 is fixedly connected to two limit blocks 411, and the limit blocks 411 are used to limit the rotation angle of the rotation limiting disk 407.

[0028] When in use, the two electromagnets 409 generate magnetic attraction and magnetic repulsion on the magnets on the magnet mounting frame 408, that is, one of them attracts the magnet mounting frame 408 to fix the position of the upper cutting saw 403 or the lower cutting saw 502 below the magnet mounting frame 408, and the other generates repulsion on the magnet mounting frame 408. The magnetism of the electromagnet 409 on the magnet mounting frame 408 can be controlled to control the electromagnet 409 that attracts the magnet mounting frame 408 to quickly generate magnetic repulsion on the magnet mounting frame 408, and the other electromagnet 409 can be controlled to quickly generate magnetic repulsion on the magnet mounting frame 408. 9 quickly generates magnetic attraction to the magnet mounting frame 408, and through the action of two forces, forces the magnet mounting frame 408 to rotate 90°, thereby controlling the upper cutting saw 403 and the lower cutting saw 502 to rotate 90°, allowing the upper cutting saw 403 or the lower cutting saw 502 to change the cutting direction. In this way, when returning, the action direction of the saw blade can be aligned with the movement direction, without requiring the first linear motor 401, the second linear motor 501 or the linear drive motors on both sides of the frame to take a longer path to adapt to the action direction of the saw blade.

[0029] It should be noted that the reason for this adjustment is that it is found during the operation that the direction of action of the saw blade is fixed, while the fastest cutting path may be opposite to it. The two saw blades distributed up and down and vertically can complement each other's opposite directions of action after rotating 90°. This can save a lot of time in adjusting the position of the saw blade, allow the saw blade to participate in the cutting work faster, and effectively improve work efficiency.

[0030] Specifically, the exteriors of the upper cutting saw 403 and the lower cutting saw 502 are fixedly connected to a fixed frame 404, a special-shaped connecting rod 406 is inserted into the upper sliding part of the fixed frame 404, a spring is movably sleeved between the top of the special-shaped connecting rod 406 and the fixed frame 404, a friction block 405 is fixedly connected to the bottom of the special-shaped connecting rod 406, and the friction block 405 has a straight anti-slip strip, and a pointed head 410 is fixedly connected to the bottom of the fixed frame 404 corresponding to the position of the saw blade of the upper cutting saw 403 or the lower cutting saw 502, the bottom shape of the special-shaped connecting rod 406 is rectangular, and the upper shape of the special-shaped connecting rod 406 is cylindrical During the operation of the saw blade, the rotation of the saw blade will force the plate to vibrate to a certain extent. In order to ensure the cutting effect, the friction block 405 on the fixed frame 404 is in contact with the plate, and the movable sleeve spring is used as support to reduce the possible vibration of the plate. At the same time, the friction block 405 provides additional friction between the saw blade and the plate, which can prevent the plate and the saw blade from offsetting when the plate vibrates.

[0031] When the upper cutting saw 403 and the lower cutting saw 502 change their angles, the upper cutting saw 403 and the lower cutting saw 502 will first be lifted up and lose contact with the plate. During this process, the friction block 405 is always in contact with the plate under the support of the spring, and at the same time, the rectangular shape at the bottom of the special-shaped connecting rod 406 will completely leave the fixed frame 404, and the cylindrical shape of the special-shaped connecting rod 406 will rotate in the fixed frame 404, and then when the fixed frame 404 rotates with the upper cutting saw 403 or the lower cutting saw 502, the friction block 405 is still in contact with the plate, and the friction force is used to prevent the straight anti-slip strip of the friction block 405 from deviating from the plate as much as possible. When the upper cutting saw 403 or the lower cutting saw 502 is pressed down again, the spring on the special-shaped connecting rod 406 will be stretched again, and the rectangular part of the special-shaped connecting rod 406 will be reinserted into the fixed frame 404, and the rectangular shape is used to limit the rotation of the friction block 405, thereby further improving the stability of cutting.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
