[0014] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment 1

[0016] like Figure 1 and Figure 2 As shown, the utility model proposes a vehicle bottom cover clamping and fixing device, including a base 1, on which a plurality of installation stations for placing workpieces 6 are provided, the plurality of installation stations are arranged along the length direction of the base 1, and the plurality of installation stations are distributed and arranged in a stepped manner from one side of the length direction of the base 1 toward the other side to avoid mutual interference between the workpieces 6, and clamping mechanisms are provided on both side ends of the distribution direction of any installation station, the clamping mechanism includes a driving member 4, a pressing plate 2 arranged on the top end surface of the base 1 and driven by the driving member 4, and the pressing plate 2 is provided with end walls extending toward the installation stations on both sides thereof, which are used to cooperate with the installation stations to clamp and fix the workpieces 6 installed at both ends of the pressing plate 2 at the same time.

[0017] In the embodiment, the installation station includes a positioning block 3 protruding from the top end face of the base 1, and a workpiece 6 is clamped on the positioning block 3. Limit blocks 5 are also provided on both sides of the positioning block 3. The limit blocks 5 are respectively in contact with the side walls at both ends of the workpiece 6. The limit blocks 5 provided on both sides of the positioning block 3 are used to limit the degree of freedom of the workpiece 6 to prevent the workpiece 6 from loosening due to force during processing.

[0018] In the embodiment, the output end of the driving member 4 is drivingly connected to the pressing plate 2 through the base 1, and the end walls on both sides of the pressing plate 2 can movably abut against the top end surfaces of the workpiece 6 fixed on the positioning blocks 3 on both sides of the clamping mechanism.

[0019] In the embodiment, a mounting hole 7 penetrating the pressing plate 2 is provided in the middle of the pressing plate 2, and an internal thread is provided on the inner wall of the mounting hole 7. The pressing plate 2 is detachably connected to the output end of the driving member 4 by bolts passing through the mounting hole 7.
