[0022] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0023] (1) The cabin processing and clamping device provided by the present invention can position and clamp the cabin workpiece by setting a chassis assembly, a pressure plate, a tensioning assembly and a clamping assembly. The cabin workpiece is quickly positioned by the arc-shaped protrusion on the pressure plate and the arc-shaped positioning block and positioning pin on the chassis. The pressure plate and the chassis are matched by the tensioning assembly to tighten the position of the cabin workpiece. The position of the window on the cabin workpiece is fixed by the clamping assembly, thereby clamping the cabin workpiece. The cabin processing and clamping device can also process the inner cavity of the cabin workpiece by the arc-shaped positioning block and the clamping assembly, so that the small-diameter end frame of the cabin workpiece is sleeved on the arc-shaped positioning block, so that the arc-shaped positioning block is close to the inner wall of the small-diameter end frame sleeve, and the clamping assembly is adjusted so that the clamping plate fixes the position of the window, so that the small-diameter end frame sleeve of the cabin workpiece is connected to the chassis assembly, which is convenient for processing the inner cavity of the cabin workpiece.

[0024] (2) The cabin processing clamping device provided by the present invention can adjust the positions of the baffle plate and the arc-shaped protrusion according to the diameter of the end frame of the cabin workpiece by setting a baffle plate adjustment member on the chassis assembly and setting a protrusion adjustment member on the pressure plate, so that the cabin processing clamping device can clamp and position the cabin workpiece with different end frame diameters. A first arc groove is set on the first gear plate, and the baffle plate is connected to the first gear plate through the first arc groove. The baffle plate can be retracted outward or expanded inward by the rotation of the first gear plate, so that the baffle plate is closely attached to the inner wall of the large diameter end frame of the cabin workpiece; the second moving head is set in the second arc groove, and the second moving head can move along the second arc groove with the rotation of the second driving gear, and the arc-shaped protrusion is displaced by the second connecting block, so that the circular ring surrounded by the arc-shaped protrusion is enlarged or reduced, so that the arc-shaped protrusion can be closely attached to the inner wall of the small diameter end frame of different cabin workpieces, so that the cabin processing clamping device can adjust different cabin workpieces.

When the cabin workpiece is clamped, the pressure plate is pressed and fixed in position by tightening the fixing nut, and the large-diameter end frame of the cabin workpiece squeezes the positioning ball, so that the positioning ball moves into the ball hole, squeezes the compression spring, and lifts the other end of the connecting plate, so that the prompt piece protrudes from the column hole, reminding the technician to prevent excessive compression from causing skin deformation. When testing the clamping state of the cabin workpiece, the cabin workpiece is tilted at a certain angle. If the cabin workpiece is not fixed firmly, a gap will appear between the large-diameter end frame of the cabin workpiece and the chassis during the tilting process, so that the positioning ball at the gap protrudes from the ball hole under the action of the compression spring, driving the end of the connecting plate connected to the prompt piece to drop, so that the indicator piece enters the column hole, reminding the technician to adjust the fixing nut again. By setting up a clamping reminder unit, technicians can be reminded to avoid over-tightening when adjusting the fixing nut, thereby preventing the pressure plate from being over-pressed and causing deformation of the skin; at the same time, the clamping reminder unit can also display the clamping state of the cabin workpiece, which is convenient for checking the clamping state of the cabin workpiece, so as to timely adjust the clamping degree of the cabin workpiece, improve the safety and stability of the cabin processing clamping device, facilitate the detection of the clamping state of the cabin workpiece, and improve the efficiency of checking the clamping state of the cabin workpiece.

The first moving head 1112 is provided in the first arc groove 1411. When the first driving gear 142 drives the first gear plate 141 to rotate, the first moving head 1112 moves along the first arc groove 1411 with the rotation of the first driving gear 142. The baffle 111 is displaced via the first connecting block 1111, so that the circular ring surrounded by the baffle 111 is enlarged or reduced, thereby enabling the baffle 111 to be closely attached to the inner wall of the large-diameter end frame of different cabin workpieces 5.

[0057] Preferably, a slider is provided on the baffle 111 and a slide rail is provided on the chassis 11, so that the baffle 111 and the chassis 11 are connected via the slider and the slide rail, so that the baffle 111 can move along the slide rail, thereby increasing the stability of the movement of the baffle 111.

[0066] Example 3

[0067] This embodiment provides a cabin body processing clamping device, such as Fig. 9 As shown, the difference from Example 1 or Example 2 is that it also includes a clamping prompt unit 6, which is used to prevent the tensioning assembly 3 and the pressure plate 2 from excessively squeezing the cabin workpiece 5 to cause the skin to be compressed and deformed, and to indicate the clamping state of the cabin workpiece 5.

A ball hole is set on the shell 66, and the ball hole matches the position of the positioning ball 62.

When the cabin workpiece 5 contacts the chassis 11, the positioning ball 62 can be squeezed to compress the compression spring 65; a column hole is also set on the shell 66, and the position of the column hole matches the prompt member 61, so that the prompt member 61 can protrude from the column hole.

[0069] Preferably, the clamping prompting units 6 are provided in plurality and distributed along the circumference of the chassis 11 , thereby increasing the accuracy of the clamping prompting units 6 in indicating the clamping state of the cabin workpiece 5 .

[0070] Preferably, a slide groove is provided on the chassis 11 , and the housing 66 is provided in the slide groove. The housing 66 can move along the slide groove, so that the position of the clamping prompt unit 6 can be adjusted according to the position of the baffle 111 .

[0071] When the cabin workpiece 5 is clamped, the pressure plate 2 is pressed and fixed in position by tightening the fixing nut 32. The large-diameter end frame of the cabin workpiece 5 squeezes the positioning ball 62, which moves the positioning ball 62 into the ball hole, squeezes the compression spring 65, and lifts the other end of the connecting plate 63, so that the prompt piece 61 protrudes from the column hole, reminding the technician to prevent excessive compression from causing skin deformation.

[0072] When testing the clamping state of the cabin workpiece, the cabin workpiece 5 is tilted at a certain angle. If the cabin workpiece 5 is not firmly fixed, a gap will appear between the large-diameter end frame of the cabin workpiece 5 and the chassis 11 during the tilting process, so that the positioning ball 62 at the gap protrudes from the ball hole under the action of the compression spring 65, driving the end of the connecting plate 63 connected to the prompt member 61 to descend, so that the indicator member 61 enters the column hole, reminding the technician to adjust the locking nut 32 again.

[0073] By setting up the clamping prompt unit 6, the technician can be reminded to avoid over-tightening when adjusting the locking nut 32, so as to prevent the pressure plate 2 from being over-pressed and causing deformation of the skin; at the same time, the clamping prompt unit 6 can also display the clamping state of the cabin workpiece 5, which is convenient for checking the clamping state of the cabin workpiece 5, so as to timely adjust the clamping degree of the cabin workpiece 5, improve the safety and stability of the cabin processing clamping device, facilitate the detection of the clamping state of the cabin workpiece, and improve the efficiency of checking the clamping state of the cabin workpiece.
