[0015] This invention provides an automated hydraulic cutting device for the side panels of automobile cargo boxes, which has the following advantages:

[0016] (1) The present invention is equipped with an automated hydraulic cutting device for the side panel of a car cargo box. When it is necessary to grind the hydraulically cut surface, the second fixing block plays a role in fixing and clamping the side panel. The second fixing block slides towards one side of the grinding device through the drive wheel. The third sliding block slides in the sliding groove. The grinding block contacts the cut surface of the side panel, thereby grinding the side panel.

[0017] (2) The present invention is equipped with a turntable and casters. After the side plate on one side is polished, the side plate is slid to the left by the second fixing block. When the hydraulic rod lifts the side plate, the turntable is rotated by the first motor. The bottom of the side plate is supported by the casters. The turntable drives the side plate to rotate, so that the side plate can rotate to the next cutting surface for polishing.

[0018] (3) By providing a clamping device, when the side plate is placed on the left side of the first arc rod, the second sliding block moves to the right by pressing down the first arc rod. The extension of the second arc rod supports the bottom of the side plate. The pressing down of the left side of the first arc rod fixes the top of the side plate on the right side. The sliding of the second sliding block allows one side of the side plate to contact the grinding device.

[0019] (4) The present invention is equipped with a grinding device. When grinding edge plates of different thicknesses, the rotation of the second motor causes the side of the grinding block to contact the cut surface of the edge plate. The downward pressure of the fourth sliding block causes the second rotating rod to exert a certain friction on both sides of the edge plate, thereby grinding the cut surface of the edge plate.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: See Figures 1-4 The present invention provides a technical solution: an automated hydraulic cutting device for the side panels of a car cargo box, comprising a base 1, with four support legs 2 fixedly connected to the bottom of the base 1, the four support legs 2 being symmetrically arranged about the central axis of the base 1, a drive wheel 103 rotatably connected to the inner wall of the base 1 via a rotating shaft, a first through hole 101 opened on the right side of the base 1, and a sliding groove 102 opened on the inner wall of the first through hole 101, and further comprising:

[0031] The clamping device 4 includes a second fixing block 402 that is rollably connected to the drive wheel 103. A first fixing block 401 is fixedly connected to the right side of the second fixing block 402. There are two second fixing blocks 402, which are symmetrically arranged about the central axis of the first fixing block 401. A first elastic component 403 is fixedly connected to the left outer wall of the second fixing block 402. A protrusion 405 is fixedly connected to the top surface of the second fixing block 402. The present invention provides an automated hydraulic cutting device for the side panel of a car cargo box. When it is necessary to grind the hydraulically cut surface, the second fixing block 402 fixes and clamps the side panel. The drive wheel 103 causes the second fixing block 402 to slide toward one side of the grinding device 5. The sliding of the third sliding block 501 in the sliding groove 102 and the contact between the grinding block 504 and the cut surface of the side panel result in the grinding of the side panel.

[0032] The grinding device 5 includes a third sliding block 501 slidably connected to the inner wall of the sliding groove 102. A second motor 502 is fixedly connected to the inner wall of the third sliding block 501. A rotating shaft 503 is fixedly connected to the output end of the second motor 502. A grinding block 504 is fixedly connected to the side of the rotating shaft 503 away from the second motor 502. The drive wheel 103 pushes the second fixed block 402 toward one side of the grinding device 5. Through the sliding of the third sliding block 501 in the sliding groove 102, the grinding block 504 at the top of the second motor 502 grinds the cut surface of the side plate. Through the downward sliding of the fourth sliding block 5042, the second rotating rods 5045 on both sides deflect toward the middle side. Through the contact between the second rotating rods 5045 and the two sides of the cut surface of the side plate, the side plate is ground.

[0033] A first groove 104 is provided at the central axis of the base 1, and a second groove 105 is provided on the top surface of the base 1. A hydraulic rod 3 is provided at the bottom of the first groove 104, and a first motor 301 is fixedly connected to the top of the hydraulic rod 3. The output end of the first motor 301 passes through the first groove 104 and is fixedly connected to a turntable 302.

[0034] A support rod 303 is fixedly connected to the outer wall of the hydraulic rod 3. A support column 304 is fixedly connected to the top surface of the support rod 303. A first sliding block 305 is rotatably connected to the top surface of the support column 304 via a rotating shaft. A universal wheel 306 is fixedly connected to the top surface of the first sliding block 305 through the second groove 105. In this invention, by setting a turntable 302 and a universal wheel 306, after the side plate cut surface on one side is ground, the side plate is slid to the left by the second fixing block 402. When the hydraulic rod 3 lifts the side plate, the turntable 302 is rotated by the first motor 301. The bottom of the side plate is supported by the universal wheel 306. The turntable 302 drives the side plate to rotate, so that the side plate can rotate to the next cut surface for grinding.

[0035] Example 2: Please refer to Figures 5-8 Based on Embodiment 1, the present invention provides a technical solution: the inner wall of the protrusion 405 is rotatably connected to a first arc-shaped rod 4051 via a rotating shaft; a second through hole 4052 is opened on the right inner wall of the first arc-shaped rod 4051; a second elastic component 4053 is fixedly connected to the bottom left side of the first arc-shaped rod 4051; and a first rotating rod 404 is provided on the outer wall of the first arc-shaped rod 4051. The present invention, by providing a clamping device 4, when the side plate is blocked on the left side of the first arc-shaped rod 4051, the second elastic component 4053 is pressed down by the first arc-shaped rod 4051. The sliding block 4062 moves to the right, and the extension of the second arc-shaped rod 4063 provides support to the bottom of the side plate. The right side of the first arc-shaped rod 4051 fixes the top of the side plate by pressing down on the left side. The sliding of the second sliding block 4062 allows one side of the side plate to contact the grinding device 5. When the left side of the first arc-shaped rod 4051 is pressed down, the right side of the first arc-shaped rod 4051 flips around the protrusion 405, and the right side of the first arc-shaped rod 4051 clamps the top surface of the side plate.

[0036] The bottom of the first rotating rod 404 is rotatably connected to the second fixed block 402. A third fixed block 4041 is fixedly connected to the inner wall of the central axis of the first rotating rod 404. A first spring 4042 is fixedly connected to the right side of the third fixed block 4041. The end of the first spring 4042 away from the third fixed block 4041 is fixedly connected to the second fixed block 402. The top of the first rotating rod 404 is slidably connected to the first arc-shaped rod 4051 through a rotating shaft.

[0037] A third groove 406 is formed on the inner left side of the second fixed block 402. A first fixed shaft 4061 is fixedly connected to the inner wall of the third groove 406. A second sliding block 4062 is provided on the outer side of the third groove 406. A second arc-shaped rod 4063 is rotatably connected to the back of the second sliding block 4062 via a pivot. The central axis of the second arc-shaped rod 4063 is slidably connected to the first fixed shaft 4061. A second spring 4064 is fixedly connected to the back of the second sliding block 4062. The second spring 4064 is located away from the second sliding block 4062. One end of 62 is fixedly connected to the groove. When the cut surface of the side plate needs to be polished, the worker places the side plate on the left side of the first arc rod 4051. The weight of the side plate presses down the first arc rod 4051. After the first arc rod 4051 is pressed down, the second elastic component 4053 at the bottom of the first arc rod 4051 pushes the second sliding block 4062 into the third groove 406. The movement of the second sliding block 4062 pushes out the second arc rods 4063 on both sides and provides support for the bottom of the side plate.

[0038] A second fixed shaft 5041 is fixedly connected to the inner wall of the grinding block 504. A fourth sliding block 5042 is movably sleeved on the outer wall of the second fixed shaft 5041. A third spring 5043 is fixedly connected to the bottom of the fourth sliding block 5042. The bottom of the third spring 5043 is fixedly connected to the grinding block 504. A third arc-shaped rod 5044 is rotatably connected to the outer wall of the fourth sliding block 5042 via a rotating shaft. A second rotating rod 5045 is rotatably connected to the end of the third arc-shaped rod 5044 away from the fourth sliding block 5042 via a rotating shaft. The right side of the second rotating rod 5045 is rotatably connected to the grinding block 504 via a rotating shaft. By setting up a grinding device 5, when grinding edge plates of different thicknesses, the rotation of the second motor 502 causes the side of the grinding block 504 to contact the cut surface of the edge plate. The downward pressure of the fourth sliding block 5042 causes the second rotating rod 5045 to exert a certain friction on both sides of the edge plate, thereby grinding the cut surface of the edge plate.
