[0039] The height adjustment mechanism 3 is provided with at least two telescopic ends 321 that move in the vertical direction, and the telescopic ends 321 adjust the horizontality and position height of the box body 4 .

[0040] In the present application, the support seat 1 is used for the rough positioning of the box body 4 to prevent the box body 4 from directly hitting the height adjustment mechanism 3. The box body 4 is hoisted on the support seat 1; the paired clamping blocks 231 on the centering clamping mechanism 2 push and clamp the box body 4 from the left and right sides to the preset position, such as: making the center line of the box body 4 coincide with the X-axis of the machine tool; a telescopic end 321 of the height adjustment mechanism 3 extends upward to support the local surface of the box body 4 to form a support point; different telescopic ends 321 have different extension heights, so that different support points have different position heights to adapt to the shape and position changes of the local surface of the box body 4, thereby adjusting the horizontality and position height of the box body 4. The present application adjusts the horizontal position of the box body 4 by the centering clamping mechanism 2, and adjusts the horizontality and position height of the box body 4 by the height adjustment mechanism 3, so as to achieve rapid clamping of the box body 4, reduce the time of manual adjustment, and thus solve the problem of long clamping time of the box body 4 of the automobile crane frame during machining production, thereby achieving the effect of improving operation efficiency.

[0041] Specifically, the centering clamping mechanism 2 spans the bottom surface of the box 4, and the middle part thereof is lower than the top of the support base 1. The centering clamping mechanism 2 is located at the bottom of the box 4 to avoid obstructing the vertical lifting of the box 4. The middle part of the centering clamping mechanism 2 is lower than the top of the support base 1 to prevent the placed box 4 from being squeezed.

[0042] Specifically, the support seat 1 and the centering clamping mechanism 2 are each provided with two groups, which are respectively located at the front and rear of the box body 4.

[0043] In some embodiments, the box clamping fixture is installed on the workbench of the machine tool through fasteners. With the center line of the workbench as the reference, four sets of height adjustment mechanisms 3, two sets of support seats 1 and two sets of centering clamping mechanisms 2 are arranged symmetrically from the inside to the outside. That is, the front of the workbench is provided with one set of centering clamping mechanisms 2, one set of support seats 1 and two sets of height adjustment mechanisms 3 from front to back, and the rear of the workbench is provided with two sets of height adjustment mechanisms 3, one set of support seats 1 and one set of centering clamping mechanisms 2 from front to back. The height adjustment mechanism 3 is located at the bottom of the box 4, and the initial height of its telescopic end 321 is lower than the top of the support seat 1, and the telescopic end 321 supports the bottom surface of the box 4.

[0044] like Figure 4 As shown, specifically, the centering clamping mechanism 2 includes:

[0045] The first body 21 spans the left and right sides of the box 4;

[0046] The linear guide rail 22 is horizontally mounted on the first body 21 along the left-right direction;

[0047] There are two sliding seats 23, which are sleeved on the linear guide rail 22, and the tops of which are respectively hinged with clamping blocks 231;

[0048] The forward and reverse screw pair 24 is installed on the first body 21 and drives the two sliding seats 23 to move towards or in opposite directions at the same time;

[0049] The power assembly 25 is mounted on the first body 21 and drives the forward and reverse screw pairs 24 to rotate.

[0050] Furthermore, the forward and reverse screw pair 24 includes forward and reverse screw rods and nut seats; both ends of the forward and reverse screw rods are installed on the first body 21 through bearing seats, and one end is connected to the power assembly 25; two nut seats are sleeved on the forward and reverse screw rods and are respectively fastened to the two sliding seats 23.

[0051] Furthermore, the power assembly 25 is an electric motor or a hydraulic motor.

[0052] In the present application, the forward and reverse screw rod is a screw rod with opposite thread rotation directions at both ends, and two nut seats are respectively sleeved on the threads at both ends. The power assembly 25 drives the forward and reverse screw rods to rotate, and the nut seats driven by the forward and reverse screw rods move toward or in the opposite direction at the same time, thereby driving the sliding seat 23 and its clamping block 231 to clamp or loosen the box body 4.

[0053] In some embodiments, the first body 21 of the centering clamping mechanism 2 spans the bottom of the box 4 in the left-right direction. Two sets of linear guide rails 22 are installed in parallel on the upper surface of the first body 21 along the front and back to fully support the sliding seat 23. The clamping block 231 is hinged on the sliding seat 23, and clamps the left and right surfaces of the box 4 at an adaptive angle. The positive and negative lead screw pairs are located between the two sets of linear guide rails 22. A dust cover is provided above the linear guide rails 22 and the positive and negative lead screw pairs 24.
