The working principle of the device comprises the following steps:

first step, installation of the profiling block 10:

the lower surface of the contour block 10 is lapped above a blocking wall 212 between the limiting rollers 207 on the two second connecting plates 210, the horizontal position of the contour block 10 on the second connecting plates 210 is adjusted, so that the arc-shaped cutting guide groove 20 on the contour block 10 can be just opposite to the limiting guide roller 501 of the workpiece guide mechanism 5, the limiting guide roller 501 is driven to ascend and penetrate through the arc-shaped cutting guide groove 20 above, and the limiting guide roller 501 is in contact with the groove walls at two ends of the arc-shaped cutting guide groove 20.

Subsequently, the drive motor 216 rotates to synchronously rotate the two threaded rods 213 connected by the belt 215, and the first connecting plate 209 is fitted over the threaded rods 213 and lifted along the threaded rods 213. The distance between the first connection plate 209 and the second connection plate 210 below is changed so that the upper and lower ends of the contour block 10 can be positioned between the blocking wall 212 of the first connection plate 209 and the blocking wall 212 of the second connection plate 210.

At this time, the second power mechanism 206 is activated, so that the second power mechanism 206 pushes the movable clamping plate 205 to move along the sliding frame 201 toward the fixed clamping plate 204. The side walls of both ends of the contour block 10 contact the inner side walls of the two side rotary cores 211. At this time, the up-and-down direction of the contour block 10 and the sidewalls of both ends thereof are limited and can move only in the direction perpendicular to the lower guide rail 103.

And secondly, connecting the workpiece clamping mechanism 3 and the profiling block 10, and adjusting the positions of the workpiece clamping mechanism and the profiling block:

the lifting plug board 306 connected on the guide rail connecting board is adjusted to be opposite to the plug groove 40 of the lower profile block 10, and the lifting plug board 306 is driven to descend and be plugged in the plug groove 40.

The first power mechanism 203 is driven to enable the sliding frame 201 to slide along the lower guide rail 103, the profile modeling block 10 mounted on the sliding frame 201 slides relative to the limiting guide roller 501 to a cutting starting position where the limiting guide roller 501 aligns with the arc-shaped cutting guide groove 20, in the process, due to the limiting support of the limiting guide roller 501 on the side wall of the arc-shaped cutting guide groove 20, the profile modeling block 10 where the arc-shaped cutting guide groove 20 is located horizontally slides along the limiting roller 207 in a direction perpendicular to the lower guide rail 103, and a guide rail connecting plate (not shown in the figure) in limiting connection with the profile modeling block 10 through the lifting plug board 306 can move synchronously with the profile modeling block 10;

step three, mounting the seat track plate 30:

the two ends of the seat track plate 30 are lapped on the upper surfaces of the smooth surface clamping plates 305 at the two ends of the guide rail connecting plate, and the smooth surface clamping plates 305 are smooth in surface, so that the adjustment of the seat track plate 30 on the surface position of the smooth surface clamping plates 305 is facilitated, the cutting starting end of the seat track plate 30 is just opposite to the upper part of the limiting guide roller 501, and the telescopic air cylinder is driven to enable the rough surface clamping plate 304 to be pressed down on the upper surface of the seat track plate 30, so that the fixed installation of the seat track plate 30 is realized.

Step four, cutting:

the first power mechanism 203 is started again, the first power mechanism 203 drives the profiling block 10 connected with the first power mechanism to slide from the cutting starting end to the cutting tail end of the arc-shaped cutting guide groove 20 relative to the arc-shaped cutting guide groove 20 on the profiling block 10 under the guiding action of the limiting guide roller 501, in the process, due to the reverse acting force of the limiting guide roller 501 on the arc-shaped cutting guide groove 20, the position of the profiling block 10 changes, and the seat track plate 30 which is connected with the limiting guide roller in an up-and-down opposite mode also passes through the cutting of the cutting tool 401 with the same cutting track as the profiling block 10.

According to the invention, through the matching among the guide rail support frame 1, the profiling clamping mechanism 2, the workpiece clamping mechanism 3, the cutting structure 4 and the workpiece guide mechanism 5, the cutting starting end of the limiting guide roller 501 of the workpiece guide mechanism 5 relative to the arc-shaped cutting guide groove 20 on the profiling block 10 can be quickly positioned, and in the process that the limiting guide roller 501 slides relative to the arc-shaped cutting guide groove 20, the seat track plate 30 which is just opposite to and connected with the profiling block 10 up and down is also cut by the cutting structure along the same track, so that the device can be suitable for cutting the arc-shaped guide rail on the seat track plate 30, and the semi-automatic machining efficiency of the automobile arc-shaped guide rail is favorably improved.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
