[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1 The flip-type clamping device with horizontal adjustment and positioning comprises a horizontal positioning part 1 and a supporting and limiting part 2, wherein the horizontal positioning part 1 is provided with a positioning base 11, and the relative position of the positioning base 11 and the supporting and limiting part 2 is fixedly arranged, and the supporting and limiting part 2 is used to support and place the workpiece to be clamped; the positioning base 11 is provided with a positioning module 3 and a clamping module 4, and the positioning module 3 is arranged to move in the horizontal direction, and the clamping module 4 is arranged to flip and swing relative to the positioning base 11, and the clamping module 4 cooperates with the supporting and limiting part 2 and the positioning module 3 to clamp the workpiece to be clamped.

[0014] This solution can be used for positioning and clamping special-shaped panels. Vertical limiting is performed by the support limiting part, and horizontal positioning is performed by the positioning module. Among them, the horizontal position of the positioning module can be adjusted to avoid mutual interference when vertical and horizontal positioning are performed at the same time. First, it can provide suitable avoidance space through movement adjustment, and first complete the constraint limiting in a single direction, making the positioning and installation process easier. Second, it can utilize the constraint relationship in two directions. When the positioning module is moved into place horizontally, it and the support limiting part work together to form two constraint forces with an angle on the workpiece to be clamped, which can make the position of the workpiece to be clamped more accurate and reliable. Finally, the clamping module firmly presses the positioned workpiece to achieve the purpose of accurate positioning and clamping. It can be applied to the welding operation of special-shaped panels.

[0015] The positioning module 3 is provided with a positioning block 31, the positioning block 31 is connected to the output end of the horizontal movement drive device 30, the positioning block 31 is laterally attached to the surface of the workpiece to be clamped, and a positioning pin 32 is provided on the positioning surface of the positioning block 31, and the positioning pin 32 is arranged parallel to its horizontal movement direction. Preferably, the positioning block 31 is provided with a plurality of positioning surfaces, and the positioning pin 32 is respectively arranged on each positioning surface.

[0016] The lateral surface of the workpiece is made parallel to the locating surface of the locating block by cooperating the locating pin with the locating hole reserved on the workpiece. The horizontal moving drive device 30 can adopt a cylinder structure. When positioning and clamping, the locating block is driven to a suitable position by the cylinder, and then the locating hole of the workpiece is correspondingly sleeved with the locating pin, so that the workpiece can be moved and adjusted along the axial direction of the locating pin until the lower surface of the workpiece is completely in contact with the supporting surface of the support limit part 2, and then the clamping module is used to clamp the workpiece to ensure accurate positioning and clamping.

[0017] The clamping module 4 is provided with a rocker arm 41, which is driven to swing up and down by a flip driving device 40, and a plurality of pressing blocks are provided at the swinging end of the rocker arm 41, and the pressing surface of the pressing block is adapted to fit the upper surface of the workpiece to be clamped. The flip driving device 40 can use a combination of a cylinder and a connecting rod mechanism to realize the up and down swinging drive of the rocker arm, and a limit structure can be provided on the positioning base to limit the swinging limit position of the rocker arm.

[0018] The pressing block comprises an upper pressing block 42 corresponding to the support limiting part 2 and a side pressing block 43 corresponding to the positioning block 31 . A pin hole is provided on the pressing surface of the side pressing block 43 , and the positioning pin 32 is inserted and matched with the pin hole.

[0019] When the workpiece to be clamped is completely fitted and attached to the support and limit part 2, the rocker arm is swung down to make each pressure block fit the upper surface of the workpiece, wherein the upper and lower blocks are pressed tightly on the workpiece and the support and limit part 2, and the side pressure block is pressed against the workpiece, and the pin hole on it is aligned with the positioning hole on the workpiece. At this time, the positioning block is driven to approach the workpiece, so that the positioning pin extends into the pin hole until the positioning block presses the workpiece and the side pressure block, and the workpiece is completely positioned and clamped. The positioning and clamping accuracy is greatly improved, and after being fully clamped, the positioning pin constrains the swing of the rocker arm, which can avoid the phenomenon of clamping loosening due to misoperation in subsequent welding and other processing, and effectively ensure the stability of the positioning and clamping.
