Background
With the rapid development of the aviation field in China, all parts are developed towards the direction that an integral structure replaces a split welding structure. This brings great difficulties to the machining: the integral piece has a complex structure and insufficient rigidity, and the deformation in the machining process is difficult to control, so that the machining quality of the product is influenced; therefore, when the machining fixture is designed, an auxiliary supporting device is added at a position with poor product rigidity so as to improve the rigidity. Conventional supports are usually bolts, jacks and other accessories; however, there are certain problems in the application process: the conventional up-and-down adjusting auxiliary support sometimes has no operation space in the Z direction, and sometimes the position where the support needs to be placed is too far away from the outer edge of the part on the XY plane to be operated. Therefore, large-scale and integral products of aviation products require matched technological equipment to have strong adaptability and convenient assembly and disassembly, and can realize the control of the up-and-down adjustment of the supporting block through radial operation so as to solve the problems that no operation space exists in the Z direction and the place needing to be placed and supported is too far away from the outer edge of a part on the XY plane to be operated.

the longitudinal wedge block supporting device mainly comprises a support 1, an inclined plane sliding shaft 2, a screw rod 3 and an inclined plane guide post 7.
A stepped hole is formed in the support 1 along the X direction, the inclined sliding shaft 2 is installed at one end of the large hole, and the inner wall of the stepped hole is in sliding fit with the inclined sliding shaft 2; one end of the screw rod 3 is provided with a threaded handle 5, and the other end of the screw rod is inserted into one end of a small hole in the stepped hole, and the small hole is used for guiding the screw rod 3; one end surface of the left side end surface and the right side end surface of the support 1 is contacted with the end surface of the threaded handle 5, and the other end surface is closed and clamped through the matching of a baffle plate 9 and a screw 10; the bottom of the support 1 is provided with a countersunk hole along the Y direction, and the support 1 is screwed on the bottom plate through an inner hexagon screw 11.
A through hole is arranged at the contact part of one end of the inclined sliding shaft 2 and the end part of the screw rod 3, and the inclined sliding shaft 2 is connected with the screw rod 3 through a cylindrical pin 6.
The screw rod 3 is sleeved with a compression spring 4, and the compression spring 4 is arranged between the inclined plane slide shaft 2 and the small hole end face of the support 1.
The top of the support 1 is provided with a through hole along the Y direction for installing the inclined guide post 7, the through hole is in sliding fit with the inclined guide post 7, and the through hole is communicated with the large hole of the stepped hole; the upper surface of the inclined plane slide shaft 2 and the lower surface of the inclined plane guide post 7 are respectively provided with an inclined plane and are contacted with each other; the inclined guide post 7 is provided with a threaded hole for mounting a support 8.
The inclined plane sliding shaft 2 moves horizontally through the threaded transmission of the threaded handle 5 and the threaded rod 3, so that the inclined plane guide pillar 7 moves up and down through the inclined plane to play a supporting role, and the supporting position is fixed through the self-locking of the threads and the self-locking of the inclined plane.
