[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Reference Figure 1-4As shown, this utility model discloses an automatic positioning and leveling hydraulic clamping device for slab samples, including: a workbench 1 and a PLC controller; the top of the workbench 1 is provided with a positioning seat 2, a bracket 3, a side-push electric cylinder 4, and a rear positioning plate 5; the bracket 3 is located on the right side of the positioning seat 2; a positioning cylinder 6 is provided on the bracket 3; the positioning cylinder 6 is located above the positioning seat 2; the side-push electric cylinder 4 and the rear positioning plate 5 are respectively located on the front and rear sides of the positioning seat 2; multiple clamping cylinders 18 are evenly distributed on the left side of the top of the positioning seat 2; multiple parallel leveling electric cylinders 7 are provided at the lower left side of the positioning seat 2; The output end of the leveling cylinder 7 is provided with a wedge 8; the wedge 8 is slidably disposed within the positioning seat 2; the positioning seat 2 has multiple guide holes corresponding to the wedge 8; the number of guide holes is the same as the number of wedges 8, and they are arranged in a one-to-one correspondence; a wedge post 9 adapted to the wedge 8 is slidably disposed within the guide hole; the upper surface of the wedge 8 is an inclined surface; the wedge post 9 is located above the wedge 8; the clamping cylinder 18 is provided with a first pressure sensor and a first displacement sensor; the leveling cylinder 7 is provided with a second pressure sensor and a second displacement sensor; the first pressure sensor, the first displacement sensor, and the second pressure sensor... Both the first and second displacement sensors are electrically connected to the PLC controller. In use, the slab sample is first placed on the positioning seat 2. The side-push electric cylinder 4 then moves to push the slab sample to the position of the rear positioning plate 5 and retracts. Subsequently, the positioning cylinder 6 above the positioning seat 2 moves downwards, and the piston of the positioning cylinder 6 reaches its endpoint, i.e., the upper zero point of the slab sample. Then, the leveling electric cylinder 7 pushes the wedge block 8 to move, which in turn drives the wedge column 9 to rise. The wedge column 9 pushes the slab sample upwards until it reaches the position of the positioning cylinder 6, completing the leveling of the slab sample. Finally, the clamping cylinder 18 clamps the slab sample, and the positioning cylinder 6 retracts, thus completing the positioning and leveling of all slab samples, facilitating subsequent processing. During this process, the first pressure sensor and the first displacement sensor monitor the internal pressure and displacement changes of the clamping cylinder 18 in real time, and the second pressure sensor and the second displacement sensor monitor the internal pressure and displacement changes of the leveling electric cylinder 7 in real time. This allows for real-time monitoring of the clamping and leveling states. By setting up a PLC controller, automated control is facilitated, avoiding overload or insufficient clamping force.

[0023] The above technical solution, through the cooperation of components such as positioning cylinders, side-pushing electric cylinders, leveling electric cylinders, wedges, wedge blocks, pressure sensors, displacement sensors, and PLC controllers, greatly improves the automation level of the clamping device, thereby effectively improving work efficiency.

[0025] In this embodiment, the cushioning pad 21 is made of polyurethane material.

[0026] In this embodiment, the outer surfaces of the wedge block 8 and the wedge post 9 are coated with a tungsten carbide coating to improve the wear resistance of the wedge block and the wedge post and extend their service life.

The fixed push plate 10 moves the movable push plate 12 under the action of the slide rod 11 and the spring 14. The movable push plate 12 pushes the slab sample towards the rear positioning plate 5 until the rear surface of the slab sample is in contact with the front surface of the rear positioning plate 5. Then the side push electric cylinder 4 drives the fixed push plate 10 to move back a certain distance, but the movable push plate 12 and the slab sample remain in contact. Then the leveling electric cylinder 7 performs the leveling operation. During this process, the slab sample can rise normally. At the same time, under the joint action of the movable push plate 12 and the rear positioning plate 5, the front and rear positions of the slab sample can be prevented from shifting, ensuring the overall positioning accuracy.

[0028] In this embodiment, a third pressure sensor 15 is provided in the middle of the side of the fixed push plate 10 near the movable push plate 12; the third pressure sensor 15 is electrically connected to the PLC controller; by setting the third pressure sensor 15, the pressure applied by the movable push plate 12 to the slab sample can be monitored in real time, thereby enabling more precise control of the extension and retraction length of the push rod of the side push electric cylinder.

[0029] In this embodiment, the positioning seat 2 is provided with a sliding groove 16 that is adapted to the wedge block 8; the number of sliding grooves 16 and the number of wedge blocks 8 are the same and they are set in a one-to-one correspondence; the wedge block 8 is slidably connected in the corresponding sliding groove 16.

[0030] In this embodiment, a linear guide rail 17 is provided at the bottom of the slide groove 16; the wedge block 8 is slidably connected to the linear guide rail 17; by setting the linear guide rail, the stability of the wedge block movement process can be improved.

[0031] In this embodiment, the side-push electric cylinder 4 is fixedly connected to the top of the workbench 1 via the electric cylinder support 19.

[0032] In this embodiment, multiple guide holes are arranged in two rows; the guide holes in the first row and the guide holes in the second row are arranged alternately.

[0035] In some other embodiments, the output end of the positioning cylinder 6 is provided with an upper positioning plate to facilitate the positioning of the slab sample.

[0036] Working principle:

[0037] In use, first place the slab sample on the positioning seat 2, then the side-push electric cylinder 4 starts to operate, driving the fixed push plate 10 to move. The fixed push plate 10, under the action of the slide rod 11 and the spring 14, drives the movable push plate 12 to move. The movable push plate 12 pushes the slab sample towards the rear positioning plate 5 until the rear surface of the slab sample is in contact with the front surface of the rear positioning plate 5. Then, the side-push electric cylinder 4 drives the fixed push plate 10 to retract a certain distance, but the movable push plate 12 remains in contact with the slab sample. Then, the leveling electric cylinder 7 pushes the wedge block 8 to move. Wedge 8 drives wedge 9 to rise, and wedge 9 pushes the slab sample to rise until the slab sample reaches the position of positioning cylinder 6, completing the leveling operation of the slab sample. During this process, the slab sample can rise normally. At the same time, under the joint action of movable push plate 12 and rear positioning plate 5, the front and rear positions of the slab sample can be prevented from shifting, ensuring the overall positioning accuracy. Finally, clamping cylinder 18 clamps the slab sample and controls the piston rod of positioning cylinder 6 and the piston rod of side push electric cylinder 4 to retract, thus completing the positioning and leveling of all slab samples, which is convenient for subsequent processing.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
