Description

Technical Field

[0001] The utility model belongs to the technical field of chassis processing equipment, and in particular relates to a chassis cover fixing fixture. Background Art

[0002] The chassis generally includes components such as the outer shell, internal components of the chassis and the cover plate. When processing, each component is generally processed by a mold and then drilled and tapped. During assembly, the cover plate located on the upper part of the chassis needs to be assembled with the chassis outer shell and the internal components of the chassis. Therefore, the drilling and tapping of the chassis cover plate are generally in the same direction, and the clamping and fixing design is relatively simple. In the existing fixture design, the pressure plate that presses the cover plate downward is generally fixed by bolts. The bolt tightening process is not highly automated and is time-consuming and labor-intensive. When there are multiple pressure plates pressing the chassis cover frame, it is difficult to make the bolt tightening force of each pressure plate consistent. The above problems will cause the chassis cover frame to be subjected to uneven pressure from the pressure plate, as well as low pressure plate fixing efficiency. Utility Model Content

[0003] The utility model aims to solve the above problems and provide a chassis cover fixing fixture, which can quickly clamp and fix the chassis cover and ensure that the chassis cover frame is subjected to substantially consistent pressing force from a pressing plate.

[0006] Furthermore, the positioning blocks are provided with at least two positioning blocks, one distributed on the left and one on the right.

[0007] Furthermore, two positioning columns are provided, one is located on the positioning block, and the other is located on the bottom plate.

[0008] Furthermore, the electric pressing devices are provided in two pairs which are symmetrical on the left and right, and the two pairs of electric pressing devices press the outer frame of the chassis cover.

[0009] Furthermore, the motors of the electric clamping device are connected to the same controller, and all the motors are controlled by the controller to rotate synchronously in the same direction, driving the lifting rods to rise or fall synchronously.

[0010] The beneficial effects of the utility model are as follows: the chassis cover fixing clamp of the utility model has a positioning block and a positioning column arranged in the middle of the bottom plate to position the cover, and electric clamping devices are arranged on both sides to clamp the frame of the cover, the electric clamping device can quickly clamp and fix the chassis cover, and can ensure that the chassis cover frame is clamped synchronously, and the clamping force is basically consistent, so the clamp has a good fixing effect and high working efficiency.
