Description

Technical Field

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

[0002] The chassis generally includes components such as chassis frame, side panels, chassis internal brackets, rear window panel and cover plate. When processing, each component is generally processed by a mold and then drilled and tapped. The rear window panel installed at the rear of the chassis has many ventilation holes due to the need for ventilation and heat dissipation. The rear window panel itself needs to be assembled with the chassis frame, and it also needs to be connected to the equipment in the chassis by screws. Therefore, there are many parts that need to be drilled and tapped. The existing fixture is simple in design. The pressure plate that presses down the rear window panel is generally fixed by bolts. The bolt tightening process is not highly automated and is time-consuming and labor-intensive. For the slender structural parts of the rear window panel with dense heat dissipation holes, the clamping support is not good, which will cause the chassis rear window panel to be partially deformed during drilling or tapping operations. The above problems will cause the chassis rear window panel to be processed in an unqualified quality and low processing efficiency. Utility Model Content

A main body fixing seat 3 is provided in the middle of the upper part of the bottom plate 1, and two positioning blocks 4, one on the left and one on the right, are provided on the main body fixing seat 3. Four arc-shaped notches 31 are provided in the front part of the main body fixing seat 3, and the vertical projection of the arc-shaped notches 31 is semicircular, and the setting position corresponds to the drilling and tapping position of the rear window panel 7 of the chassis. An L-shaped fixing seat 5 for fixing the two rear corners of the rear window panel 7 of the chassis is provided near the support plate 2 on the upper rear part of the bottom plate 1. A set of electric clamping devices 6 are respectively arranged near the left and right sides of the bottom plate 1, and the two sets of electric clamping devices 6 are arranged symmetrically on the left and right. The electric clamping devices 5 clamp the outer frame of the rear window panel 7 of the chassis; each set of electric clamping devices 6 includes a pressing plate 61, a bracket 62, a lifting rod 63 and a motor 64. The bracket 62 is fixed on the bottom plate 1, and its upper end is hinged to the middle part of the pressing plate 61. The end of the pressing plate 61 close to the outer side of the bottom plate 1 is hinged to the upper end of the lifting rod 63.
