Clamping device

Abstract

The utility model discloses a clamping device. The clamping device comprises a supporting plate, a clamping assembly and at least three profiling positioning blocks, wherein the clamping assembly and the profiling positioning blocks are arranged on the supporting plate. In the X-axis direction, the profiling positioning blocks are arranged on the supporting plate at intervals; in the Y-axis direction, the clamping assembly is arranged on one side of the profiling positioning blocks, and the clamping end of the clamping assembly faces the gap between every two adjacent profiling positioning blocks. When the clamping device is used, firstly, materials are pre-positioned on the profiling positioning blocks, due to the fact that the distance is preset between the profiling positioning blocks, part of the structure of the materials can be exposed out of the profiling positioning blocks, and therefore structural support is provided for the clamping assembly to rapidly clamp the materials from the side faces of the materials. In other words, after the clamping assembly is started, the clamping end of the clamping assembly can abut against the side face of the material and drive the material to move relative to the profiling positioning block so as to eliminate tiny gaps and achieve the fastening effect.

[0043] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0044] When locking the luggage rack of an automobile, the existing clamping device usually requires the staff to first place the luggage rack of the automobile on the corresponding positioning tooling, and then manually tighten the clamps to tighten each position of the luggage rack in turn; when the assembly work is completed, all the clamps must be manually loosened in turn to remove the luggage rack for subsequent processing. This clamping device is not only complex in structure and poor in clamping effect, but also because the clamping process is cumbersome, it will also increase the extra non-working time, thus seriously affecting the overall production efficiency.

[0045] Based on this, please refer to Figures 1 to 4 A clamping device is provided, comprising a support plate 1, a clamping assembly 2 and at least three profiling positioning blocks 3 arranged on the support plate 1; in the X-axis direction, the profiling positioning blocks 3 are arranged at intervals on the support plate 1; in the Y-axis direction, the clamping assembly 2 is arranged on one side of the profiling positioning block 3, and the clamping end of the clamping assembly 2 is arranged toward the gap between two adjacent profiling positioning blocks 3. Preferably, when the number of the profiling positioning blocks 3 is greater than three, the clamping end of the clamping assembly 2 is arranged toward the gap between two adjacent profiling positioning blocks 3 in the middle, so as to ensure that the material can be subjected to uniform force when clamped.

[0046] It can be understood that, when the clamping device of the present invention is used, the material is first pre-positioned on the profiling positioning block 3. Since there is a preset spacing between the profiling positioning blocks 3, part of the structure of the material will be exposed outside the profiling positioning block 3, thereby providing structural support for the clamping component 2 to quickly clamp the material from the side of the material. That is, compared with the existing clamping device, the clamps used in the existing clamping device can only apply downward pressure to the material in the vertical direction to fix the material on the profiling positioning block 3, while the clamping device of the present invention, after starting the clamping component 2, the clamping end of the clamping component 2 can be in contact with the side of the material. On the basis of the material being tightly attached to the positioning surface of the profiling positioning block 3 due to its own gravity, the material is further driven to move relative to the profiling positioning block 3 in the horizontal direction to eliminate the small gap, thereby improving the overall fastening effect, avoiding shaking during the assembly process, and thus improving the assembly quality.

[0047] In some embodiments, a pre-locking device 4 is further included; the locking end of the pre-locking device 4 is arranged opposite to the positioning surface of any profiling positioning block 3; when the pre-locking device 4 and the corresponding profiling positioning block 3 are locked, the locking end of the pre-locking device 4 and the positioning surface of the profiling positioning block 3 constitute a limiting structure for fixing the material. Specifically, the pre-locking device 4 is any commercially available device that can achieve a clamping effect, such as a material pressing plate or a material pressing block, etc.; and the pre-locking device 4 is connected to the profiling positioning block in any detachable manner, such as being threadedly connected to the profiling positioning block 3 through a screw member. In order to avoid the displacement between the material and the profiling positioning block 3, which affects the clamping effect of the clamping assembly 2 and ultimately causes the assembly accuracy of the material to be unsuitable for the design requirements, by setting the pre-locking device 4, a part of the material can be initially locked between the profiling positioning block 3 and the pre-locking device 4 after the material is placed on the profiling positioning block 3, thereby avoiding the displacement of the material due to shaking, thereby effectively solving the above-mentioned problem.

[0048] In some embodiments, at least two positioning grooves are provided on the positioning surface of the profiling positioning block 3 in the Y-axis direction; the notches of the positioning grooves are arranged opposite to the clamping end of the clamping assembly 2. This design makes a specific modification to the structure of the profiling positioning block 3, and by increasing the number of positioning grooves, the clamping device of the utility model can provide structural support for clamping multiple materials at the same time, thereby effectively improving the clamping efficiency of the clamping device and further improving the overall production capacity.

[0049] In some embodiments, in the Z-axis direction, the positioning surfaces of all the profiling positioning blocks 3 constitute virtual positioning surfaces. Specifically, the profiling positioning blocks 3 can be adjusted according to the profile of the material to be assembled, that is, the virtual positioning surfaces formed by all the profiling positioning blocks 3 can be arcuate or flat; and the arcuate positioning surface can be a concave surface with high ends and low middle, or a convex surface with low ends and high middle; the virtual positioning surface can even be an irregular wave shape; this design can fully improve the adaptability of the clamping device of the utility model, so that it can hold a variety of materials, thereby expanding the scope of use of the clamping device.

[0050] In some embodiments, the clamping assembly 2 includes a driving member 21, a connecting rod assembly 22 and a clamping member 23; the clamping member 23 is hinged to the support plate 1, and the clamping member 23 is arranged between the gaps between two adjacent profiling positioning blocks 3; the driving member 21 is hinged to the clamping member 23 through the connecting rod assembly 22. The design makes specific modifications to the composition structure of the clamping assembly 2. When it is necessary to clamp the material, the driving member 21 drives the connecting rod assembly 22 to drive the clamping member 23 to approach the material around the X axis, thereby achieving the clamping effect of the material; when it is necessary to remove the material, the driving member 21 drives the connecting rod assembly 22 to drive the clamping member 23 to move away from the material around the X axis, thereby achieving the unlocking effect of the material; the clamping device of the utility model can ensure the clamping stability of the material without the need to set up additional manual pressure clamps; at the same time, it can also achieve the effect of fully automatic clamping and loosening of the material, thereby effectively improving the overall working effect.

[0051] In some embodiments, in the Y-axis direction, the number of clamping members 23 is at least two; the clamping members 23 are hinged to the support plate 1, and the clamping members 23 are arranged between the gaps between two adjacent contoured positioning blocks 3. This design further optimizes the structure of the clamping assembly 2, and by providing multiple clamping members 23, structural support can be provided for the clamping device of the utility model to clamp multiple materials at the same time, thereby better improving the overall assembly efficiency.

[0052] In some embodiments, the driving member 21 is a linear driving device; the connecting rod assembly 22 includes a driving rod 221 and a connecting rod 222; one end of the driving rod 221 is hinged to the movable end of the linear driving device, and the other end of the driving rod 221 is hinged to one end of the connecting rod 222; the other end of the connecting rod 222 is hinged to the clamping member 23; the linear driving device is connected to the connecting rod 222 through the driving rod 221 to drive the clamping member 23 to rotate around the X axis; the moving direction of the movable end of the linear driving device is parallel to the Z axis. Specifically, the linear driving device is any commercially available device that can drive an object to move in a linear direction, such as a cylinder, an oil cylinder, or a linear slide. The design makes specific modifications to the component structure of the driving member 21, the component structure of the connecting rod assembly 22 and the driving direction of the driving rod 221, so that the clamping device of the utility model can achieve the effect of quick locking and quick loosening, that is, the linear driving device, the driving rod 221, the connecting rod 222 and the clamping member 23 form a connecting rod structure, when the active end of the linear driving device moves downward along the Z axis, the driving rod 221 is driven to be ejected in the direction of the connecting rod 222, so that the connecting rod 222 drives the clamping member 23 to approach the material around the X axis; conversely, when it is necessary to loosen the material, it is only necessary to reset the active end of the linear driving device to quickly loosen the material, eliminating the time wasted by the staff in opening and closing multiple clamps to complete the loosening and clamping when using the existing clamping device, thereby effectively improving the overall work efficiency.

[0053] In some embodiments, the driving member 21 is a rotary driving device; the movable end of the rotary driving device is connected to one end of the driving rod 221; the other end of the driving rod 221 is hinged to one end of the connecting rod 222; the other end of the connecting rod 222 is hinged to the clamping member 23; the rotary driving device is connected to the connecting rod 222 through the driving rod 221 to drive the clamping member 23 to rotate around the X axis; the axis of the rotary driving device is parallel to the X axis; the axis of rotation of the rotary driving device is perpendicular to the axis of the driving rod 221. Specifically, the rotary driving device is any commercially available device that can drive an object to rotate, such as a motor or a rotary cylinder. This design provides another solution that can drive the clamping member 23 to rotate close to or away from the material to achieve the clamping and unlocking effect of the material, thereby improving the adaptability of the clamping device of the utility model, and then ensuring that in any case, the clamping device of the utility model can be combined with the existing conventional driving device to complete the rapid clamping and loosening of the material.
