[0048] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0049] like Figure 1-14 As shown, a plate parallel sample clamping device includes a horizontal seat 1. The top two ends of the horizontal seat 1 are connected to an upper crossbeam 3 via flat columns 2. The bottom end of the upper crossbeam 3 is connected to a plurality of hydraulic power clamps 5. The bottom end of the hydraulic power clamps 5 is connected to a pre-tightening component 6. A lower pad 4 is provided on the horizontal seat 1. The lower pad 4 and the pre-tightening component 6 clamp the plate parallel sample. The horizontal seat 1 is also provided with a centering alignment component 7 for aligning the plate parallel sample.

[0050] In practice, the parallel sample of the plate is first clamped between the lower pad 4 and the pre-tightening component 6. Then, the centering alignment component 7 is activated by the button to center and align the parallel sample of the plate clamped between the lower pad 4 and the pre-tightening component 6. Finally, the centering alignment component 7 is reset and the hydraulic cylinder is activated to drive the hydraulic power chuck 5 to clamp the parallel sample of the plate.

[0051] Specifically, a process groove 11 is provided on the side wall of the horizontal seat 1, and the centering alignment component 7 is installed in the process groove 11.

[0052] Specifically, the hydraulic power chuck 5 is connected to the hydraulic cylinder mounted on the upper crossbeam 3. The bottom of the hydraulic power chuck 5 is cylindrical, and two second through holes 51 are provided on the side wall of the bottom end of the hydraulic power chuck 5. The two second through holes 51 are connected to the pre-tightening assembly 6 by bolts and nuts.

[0053] The preload assembly 6 is installed on the second through hole 51 at the bottom of the hydraulic power chuck 5 by means of bolts and nuts. The installation is convenient and quick, and requires little modification to the existing hydraulic power chuck 5, making it easy to promote and apply.

[0054] In this embodiment, the two second through holes 51 are perpendicular to each other. In a specific implementation, the two second through holes 51 can also be set to be parallel to each other.

[0055] Specifically, the pre-tightening assembly 6 includes an outer cylinder 61 and an inner cylinder 62 sleeved together. A spring 63 is provided inside the inner cylinder 62, and the two ends of the spring 63 abut against the bottom end of the hydraulic power chuck 5 and the bottom wall of the inner cylinder 62, respectively.

[0056] Two third through holes 611 are provided on the side wall of the top of the outer cylinder 61, and the third through holes 611 correspond to the second through holes 51; a first sliding groove 612 is provided on the inner wall of the outer cylinder 61, and a first limiting block 613 is provided at the bottom of the outer cylinder 61.

[0057] A slide bar 621 is provided on the side wall of the inner cylinder 62. The slide bar 621 is slidably connected in the first slide groove 612. A second limiting block 622 is provided at the top of the inner cylinder 62. The second limiting block 622 corresponds to the first limiting block 613.

[0058] During installation, first place the spring 63 inside the inner cylinder 62, then place the inner cylinder 62 inside the outer cylinder 61, and finally install the outer cylinder 61 at the bottom of the hydraulic power chuck 5.

[0059] Specifically, the centering alignment component 7 includes a horizontal movement component 71 and a vertical movement component 72. The horizontal movement component 71 is mounted on the horizontal seat 1, and the vertical movement component 72 is connected to the horizontal movement component 71. There are two vertical movement components 72, which are symmetrically arranged on both sides of the horizontal seat 1. When the vertical movement component 72 moves horizontally on the horizontal movement component 71, it completes the centering alignment operation of the parallel sample of the plate.

[0060] Specifically, the horizontal motion component 71 includes a base plate 711, a first lead screw 712, a horizontal slide bar 713, a horizontal slider 714, a first transmission block 715, a first motor 716, and a gear 717. Two base plates 711 are provided and symmetrically installed on both sides of the horizontal seat 1. The first lead screw 712 is rotatably connected to the two symmetrically arranged base plates 711. The body of the first lead screw 712 is provided with two threaded sections with opposite directions of rotation. The two threaded sections are located on both sides of the horizontal seat 1. Two first transmission blocks 715 are provided and are respectively connected to the two threaded sections of the first lead screw 712.

[0061] The first motor 716 is mounted on one of the base plates 711. Two gears 717 are provided and are respectively connected to the output end of the first motor 716 and the body of the first lead screw 712. The two gears 717 mesh with each other.

[0062] The horizontal slide bar 713 is connected to the two symmetrically arranged base plates 711, and the horizontal slider 714 is slidably connected to the horizontal slide bar 713. There are two horizontal sliders 714, which are respectively located on both sides of the horizontal seat 1.

[0063] The horizontal slider 714 and the first transmission block 715 are mounted on the vertical motion component 72.

[0064] Multiple horizontal slide bars 713 are provided and symmetrically distributed on both sides of the first lead screw 712.

[0065] In specific implementation, when the first motor 716 is working, it drives the first lead screw 712 to rotate through two meshing gears 717. The rotation of the first lead screw 712 drives the first transmission block 715 to slide in the limiting groove 7111. When the first transmission block 715 slides in the limiting groove 7111, it drives the vertical moving component 72 installed on the first transmission block 715 to move synchronously along the limiting groove 7111.

[0066] Since the two threaded sections on the first lead screw 712 have opposite thread directions, when the first lead screw 712 rotates, the two symmetrically arranged vertical moving parts 72 move towards each other or move away from each other at the same time.

[0067] Specifically, the vertical motion component 72 includes a bracket 721, a baffle 722, and a second motor 723. The horizontal slider 714 and the first transmission block 715 are mounted on the bottom surface of the bracket 721. A second lead screw 7211 is provided in the middle of the bracket 721. Vertical slide rods 7212 are symmetrically mounted on both sides of the bracket 721. The second motor 723 is mounted on the bottom surface of the bracket 721, and the output end of the second motor 723 is connected to the second lead screw 7211 for transmission.

[0068] The baffle 722 is T-shaped, and a limiting hole 7221 is provided in the middle of the baffle 722. The limiting hole 7221 is threadedly connected to the second lead screw 7211. Vertical sliders 7222 are installed on both sides of the baffle 722, and the vertical sliders 7222 are slidably connected to the vertical slide rod 7212.

[0069] When the second motor 723 is working, it drives the second lead screw 7211 to rotate. The rotation of the second lead screw 7211 causes the baffle 722 to rise or fall along the second lead screw 7211.

[0070] Specifically, an anti-tipping block 7213 is also installed at the bottom of the bracket 721, and the anti-tipping block 7213 corresponds to the base plate 711.

[0071] The working process of this utility model is as follows:

[0072] The process of placing the parallel plate sample is as follows: First, place the parallel plate sample on the lower pad 4. Second, the hydraulic cylinder drives the hydraulic power chuck 5 to descend. The hydraulic power chuck 5 drives the pre-tightening component 6 to abut against the parallel plate sample. At this time, the spring 63 can be further compressed.

[0073] Centering alignment operation: The second motor 723 drives the second lead screw 7211 to rotate, and the rotation of the second lead screw 7211 drives the baffle 722 to rise.

[0074] The first motor 716 drives the first lead screw 712 to rotate. The rotation of the first lead screw 712 drives the two first transmission blocks 715 connected to the first lead screw 712 to move towards each other. The two first transmission blocks 715 drive the two brackets 721 to move towards each other synchronously. The two brackets 721 drive the two baffles 722 to move towards each other. The two baffles 722 complete the centering and alignment of the parallel sample of the plate.

[0075] Reset and compaction operation: First, the first motor 716 drives the two first transmission blocks 715 to reset. Second, the second motor 723 drives the two baffles 722 to reset. Finally, the hydraulic cylinder works to press the parallel sample of the plate onto the lower pad 4. At this time, the spring 63 cannot be further compressed.
