[0001] This utility model relates to the field of clamping technology, and in particular to an adjustable clamping device that prevents wood blocks from cracking easily when compressed. Background Technology

[0002] Traditional nut clamping devices have some defects and limitations in practical applications, such as: uneven clamping force. During the clamping process, the threaded engagement between the nut and the screw may lead to uneven clamping force, which may cause deformation of the clamped wood block and affect processing accuracy; limited applicability. For wood blocks of different sizes and shapes, traditional nut clamping devices may require the replacement of nuts and screws of different specifications, which increases production costs and operational complexity.

[0003] Currently, there is no clamping device on the market that can ensure the lateral stability of small wood parts during compression. In the process of small-scale wood product processing and compression, the processed products are small in size and require multiple compression tests, which require multiple adjustments to their dimensions. Existing clamping devices cannot meet the needs very well. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable clamping device that prevents wood blocks from cracking easily when compressed. It can be adjusted in width and length to accommodate wood blocks of more shapes and different mechanical strengths, and the rubber pad can better protect the wood blocks.

[0005] To achieve the above objectives, this utility model provides an adjustable clamping device to prevent wood blocks from cracking easily when compressed, including an upper clamping unit and a lower clamping unit.

The corner brackets of the lower clamping unit are composite corner brackets. Each corner bracket is provided with several adjustment holes. A lead screw mechanism and an adjustment unit are provided at each adjustment hole. The lead screw mechanism is located at the end of the adjustment hole away from the center of the corner bracket. Several fixing nuts are provided on the lead screw mechanism located outside the adjustment hole. The adjustment unit is located at the adjustment hole near the center of the corner bracket.

[0006] Preferably, the adjustment unit includes a rubber pad and a bolt for fixing the rubber pad. The bolt passes through the rubber pad and is provided with an adjustment nut. The bolt passes through the adjustment nut and passes through the adjustment hole and is provided with a fixing nut.

[0007] Preferably, the composite corner bracket includes a first corner bracket and a second corner bracket, the first corner bracket is disposed on the inner side, the second corner bracket is disposed on the outer side of the first corner bracket, the adjusting nut is disposed between the first corner bracket and the second corner bracket, the lead screw mechanism passes through the first corner bracket and is connected to the adjusting nut, and the lead screw mechanism passes through the first corner bracket and the second corner bracket and is connected by the fixing nut.

Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1-2 As shown, this utility model discloses an adjustable clamping device to prevent wood blocks from cracking easily when compressed. It includes an upper clamping unit 1 and a lower clamping unit 2. The upper clamping unit 1 is located directly above the lower clamping unit 2. Both the upper clamping unit 1 and the lower clamping unit 2 are provided with several corner brackets 3. The corner brackets 3 of the lower clamping unit 2 are composite corner brackets 4. Each corner bracket 3 is provided with several adjustment holes 5. A lead screw mechanism 6 and several adjustment units 7 are provided at each adjustment hole 5. The lead screw mechanism 6 is located at the end of the adjustment hole 5 furthest from the center of the corner bracket 3. Several fixing nuts 74 are provided on the outside of the lead screw mechanism 6. The adjustment units 7 are located at the adjustment hole 5 near the center of the corner bracket 3. The width of the adjustment hole 5 can be adjusted via its groove to accommodate wood blocks of different widths. Combined with the adjustment of the length by the lead screw mechanism 6 and the addition or removal of fixing nuts 74, it can better accommodate wood blocks of different sizes.

[0022] The adjusting unit 7 includes a rubber pad 71 and a bolt 72 for fixing the rubber pad 71. The bolt 72 passes through the rubber pad 71 and is fitted with an adjusting nut 73. The bolt 72 passes through the adjusting nut 73 and passes through the adjusting hole 5 and is fitted with a fixing nut 74. The adjusting unit 7 can be added or removed as needed according to the actual clamping situation of the wooden block to ensure that the wooden block is in a stable and reliable clamping state. In addition, the rubber pad 71 is fixed to the corner bracket 3 by the fixing nut 74 and the adjusting hole 5. The position and number of the rubber pad 71 can also be adjusted by adjusting the tightness of the adjusting nut 73 to better adapt to the stress point of the wooden block. The number of rubber pads 71 ​​can also be increased or decreased to better fit irregular wooden blocks for clamping.

[0023] The composite corner bracket 4 includes a first corner bracket 41 and a second corner bracket 42. The first corner bracket 41 is located on the inner side, and the second corner bracket 42 is located on the outer side of the first corner bracket 41. An adjusting nut 73 is provided between the first corner bracket 41 and the second corner bracket 42. A lead screw mechanism 6 passes through the first corner bracket 41 and is connected to the adjusting nut 73.

[0025] The corner bracket 3 of the upper clamping unit 1 is connected to the first corner bracket 41 and the second corner bracket 42 in an embedded manner. There is a corner bracket 3 on each side of the upper clamping unit 1. The width of the corner bracket 3 can enter the gap left by the two pairs of composite corner brackets 4 of the lower clamping unit 2 when compressed downward, reducing the incompressible space in the height direction and leaving more ample compression space for the wooden block.

[0026] In the specific implementation process, the required height of the processed wooden block is adjusted by adjusting the vertical distance between the upper clamping unit 1 and the lower clamping unit 2, the required length of the wooden block is adjusted by the lead screw mechanism 6 and the adjustment hole 5, and finally the required width of the wooden block clamping is adjusted by the adjustment unit 7 on the adjustment hole 5.

[0027] Therefore, this utility model adopts an adjustable clamping device with the above-mentioned structure to avoid the easy cracking of wood blocks under compression. It can be adjusted in width and length to adapt to wood blocks of more shapes and different mechanical strengths. The rubber pad can better protect the wood blocks. For wood blocks with larger height, more basic clamping devices can be set to fix them to ensure better processing quality.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
