Embodiment Construction

[0033] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] see Figure 1 to Figure 4 As shown, the present invention is a digitally controlled flexible frame shape adjustment device, which can realize free shape adjustment in two directions, such as figure 1 As shown, it is composed of a moving bracket 16, a motor 19, a reducer 18, a coupling 17, a screw 11, a screw nut 9, a nut sleeve 3, an ear piece 1, a guide rod sleeve 8, a gear 20, and an angular contact bearing 13 and screw 10 etc. constitute.

[0035] Such as figure 1 As shown, the moving bracket 16 looks like a "T" shape, and has a stepped hole inside, which is used to install the coupling 17, the screw 11 and the angular contact bearing 13 for the positioning of the screw. The moving bracket is the main component of the device. Support parts and core parts.

[0036] Lead screw 11 is fixed: if figure 1 As shown, there is a step in ...

Abstract

The invention relates to a numerical control flexible device for adjusting form of a fixture. The device comprises a movable bracket which is internally provided with stepped holes; two sets of motors and speed reducers which are arranged on the movable bracket, wherein, one set of the motor and speed reducer is connected with a lead screw by a coupling, and the other set of the motor and the speed reducer is connected with a gear, and a gear rack matched with the gear is fixed on a cross beam; a lead screw which is arranged in the stepped holes of the movable bracket, wherein, one end of thelead screw is provided with an angular contact bearing and a bushing, the bushing contacts the angular contact bearing inside the stepped holes of the movable bracket, and the other end of the lead screw is fixed with a nut; a guide bar bush which is connected with the movable bracket; a nut bush, one end of which is connected with the lead screw and the other end of which is connected with a lug; a feather key which is arranged between the guide bar bush and the nut bush; a copper bush which is fixed on the inside of one end of the guide bar bush, wherein, the nut bush slides in the copper bush; and a slider one end of which is connected with the movable bracket and the other end of which is connected with a guide rail which is fixedly connected with a cross beam. The device realizes thefree form adjustment in two directions, has high form adjustment precision, and simple and compact structure.

Description

(1) Technical field [0001] The invention relates to a numerically controlled flexible frame shape adjustment device, which is used for shape adjustment and supporting of a flexible frame, and belongs to the technical field of aviation manufacturing engineering / aircraft assembly. (2) Background technology [0002] Aircraft assembly is a complicated process with relatively high technical requirements. Thousands of parts must be accurately positioned, connected, and assembled, and the workload is very heavy. Traditional aircraft assembly uses non-adjustable fixed lug jigs, and each jig can only be used for the assembly of one type of wall panel parts. The development of each new model must redesign a new assembly Type frame. This makes the research and development cycle of the aircraft very long and the cost is very high, which seriously restricts the development of my country's aircraft manufacturing industry. (3) Contents of the invention [0003] The object of the presen...
