Since the limit plate is slidably connected to the second cutting table through a slider and a slide groove, and the linkage plate is rotatably connected to the limit plate and the sliding plate through a hinge seat, when the electric push rod works and extends, the sliding plate pulls the relatively set limit plate through the linkage plate to perform a horizontal approach movement.

[0015] 2. The utility model is provided with a No. 1 cutting table, a No. 2 cutting table and a displacement mechanism. When the driving motor is working, the output end of the driving motor drives the screw to rotate. Since the screw is threadedly connected to the threaded plate, and the threaded plate is slidably connected to the workbench through a guide rod, the threaded plate moves in the horizontal direction, so that the positions of the No. 1 cutting table and the No. 2 cutting table can be easily adjusted according to actual usage requirements, so that the chip cutting machine can unload the cut chips and load the chips to be cut during the cutting process and stably limit the position, thereby improving the processing efficiency of the chips.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The following describes an embodiment of the present invention based on its overall structure.

[0024] A stable limited chip cutting machine, such as Figure 1 、 Figure 2 and Figure 5 As shown, it includes a workbench 1, a support frame 6, a hydraulic cylinder 7, a knife seat 8 and a blade 9. The top of the workbench 1 is provided with a support frame 6, and the top of the support frame 6 is installed with a hydraulic cylinder 7. One end of the hydraulic cylinder 7 is installed with a blade 9 through the knife seat 8. The chip to be cut is placed on the surface of the No. 1 cutting table 2 and the No. 2 cutting table 3, and the stable limitation of the chip to be cut is achieved by the cooperation of the limit plate 401 and the elastic pad 405. At this time, the blade 9 is controlled to move downward by the hydraulic cylinder 7, so that the cutting operation of the chip to be cut can be achieved through the blade 9.

[0025] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 It can be seen that the top of the workbench 1 is slidably connected to the No. 1 cutting table 2 and the No. 2 cutting table 3. The interior of the workbench 1 is provided with a displacement mechanism 5 connected to the No. 1 cutting table 2 and the No. 2 cutting table 3. The displacement mechanism 5 is composed of a drive motor 501, a screw rod 502, a threaded plate 503 and a guide rod 504. The drive motor 501 is installed on the mounting plate on one side of the workbench 1. The output end of the drive motor 501 is connected to the screw rod 502 connected to the workbench 1 through a bearing through a coupling. The surface of the screw rod 502 is threadedly connected to the threaded plate 503 welded to the No. 1 cutting table 2 and the No. 2 cutting table 3.

[0026] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 It can be seen that when the driving motor 501 is working, the output end of the driving motor 501 drives the screw rod 502 to rotate. Since the screw rod 502 is threadedly connected to the threaded plate 503, and the threaded plate 503 is slidably connected to the workbench 1 through the guide rod 504, the threaded plate 503 moves in the horizontal direction, so that the position of the No. 1 cutting table 2 and the No. 2 cutting table 3 can be adjusted according to actual usage requirements, so that the chip cutting machine can unload the cut chips and load the chips to be cut during the cutting process and stably limit the position, thereby improving the processing efficiency of the chips.

[0027] See Figure 1 and Figure 2 It can be seen that a guide rod 504 that passes through the threaded plate 503 is welded to the inner side of the workbench 1. Two guide rods 504 are symmetrically arranged about the central axis of the workbench 1, which can support and limit the threaded plate 503, thereby increasing the stability of the threaded plate 503 during sliding and preventing displacement.

[0028] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 It can be seen that the interior of the No. 1 cutting table 2 and the No. 2 cutting table 3 are both provided with a stable limit mechanism 4 extending to the outside, and the stable limit mechanism 4 includes a limit plate 401, a sliding plate 403 and an electric push rod 404, the limit plate 401 and the sliding plate 403 are slidably connected to the inner side of the No. 1 cutting table 2, a linkage plate 402 is connected between the limit plate 401 and the sliding plate 403, and an elastic pad 405 is provided at the top end of the inner side of the limit plate 401, the linkage plate 402 and the limit plate 401 and the sliding plate 403 all form a rotating structure through a hinge seat, and the limit plate 401 and the elastic pad 405 are both symmetrically provided with two about the central axis of the No. 1 cutting table 2, an electric push rod 404 is installed between the sliding plate 403 and the No. 1 cutting table 2, the sliding plate 403 is arranged in an I-shaped structure, the limit plate 401 is arranged in an "L"-shaped structure, and one end of the elastic pad 405 is provided with an inclined surface;

[0029] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 It can be seen that since the limit plate 401 is slidably connected to the No. 2 cutting table 3 through a slider and a slide groove, and the linkage plate 402 is rotatably connected to the limit plate 401 and the sliding plate 403 through a hinge seat, during the operation and extension of the electric push rod 404, the sliding plate 403 pulls the relatively set limit plate 401 through the linkage plate 402 to make a horizontal approaching movement. Since the elastic pad 405 is provided with an inclined surface at one end close to the chip, the elastic pad 405 gradually squeezes the top and side surfaces of the chip during the process of the limit plate 401 approaching the chip, thereby achieving stable limiting of the chip, solving the problem that the spring will become fatigued and worn after long-term use, making the limiting position unstable.

[0030] The working principle of the present invention is as follows: when using the chip cutting machine with stable limit, the chip to be cut is placed on the surface of the No. 1 cutting table 2 and the No. 2 cutting table 3, and the stable limit of the chip to be cut is achieved by the cooperation of the limit plate 401 and the elastic pad 405. At this time, the hydraulic cylinder 7 controls the blade 9 to move downward, so that the cutting operation of the chip to be cut can be achieved by the blade 9. After a chip is cut, the drive motor 501 is started, so that the output end of the drive motor 501 drives the screw rod 502 to rotate, and the threaded plate 503 moves horizontally, so that the position of the No. 1 cutting table 2 and the No. 2 cutting table 3 can be adjusted according to actual use needs, so that the chip cutting machine can unload the cut chips and load the chips to be cut during the cutting process and stably limit them, thereby improving the processing efficiency of the chips. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
