Description

Technical Field

[0001] This utility model relates to the field of aerospace parts processing technology, specifically a clamping device for aerospace parts processing. Background Technology

[0002] In the processing of aerospace parts, such as milling, drilling, and grinding, reliable fixation of the parts is required to prevent them from moving or vibrating under the action of processing forces, thereby ensuring processing accuracy and surface quality. However, existing clamping devices still have shortcomings. In order to ensure the fixation effect of aerospace parts, it is particularly important to develop a clamping device for aerospace part processing.

[0003] A clamping device for processing aerospace parts, as described in reference announcement number CN218488200U, includes a base and an N-shaped plate located above the base. The top of the N-shaped plate has four threaded holes, with a screw threaded into the inner cavity of each hole. A pressure block is installed at one end of the screw, and another end of the screw extends to the top of the N-shaped plate, with a knob installed at the extended end. A threaded ring is threaded onto the surface of the screw. This device, through a series of structural features, achieves the effect of protecting the surface of aerospace parts, adjusting the height of the N-shaped plate and pressure block according to the height of two aerospace parts, and limiting the pressure block. As can be seen from the above, although this device can be effectively used for clamping aerospace parts, it is generally not convenient to adjust the overall height of the device according to the operator's height and the usage environment, and there are still some inconveniences during use, requiring further improvement.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the clamping device for processing aerospace parts not only improves the convenience of using the clamping device, but also achieves the purpose of easily clamping and fixing aerospace parts, and also improves the applicability of the clamping device;

[0012] (1) The upper connecting seat is lifted and lowered synchronously by several second lifting cylinders, so that the base can be lifted and lowered smoothly by both sides below the base. The distance between the base and the bottom plate can be adjusted so that the overall height of the pressing device can be adjusted as needed according to the height of the personnel and the usage environment, thereby improving the convenience of using the pressing device.

[0013] (2) The upper connecting plate is driven to move downward by the first lifting cylinder, so that the upper connecting plate drives the guide cylinder to slide downward on the outer wall of the guide rod, so that the upper connecting plate drives the pressing plate to move downward smoothly through the lower connecting plate, and then the two pressing plates press down and position the aviation parts at the top of the placement table from both ends, thereby achieving the purpose of easily pressing and fixing the aviation parts.

[0014] (3) By driving the bidirectional lead screw to rotate by the motor, the two clamping plates slide towards each other on the outer wall of the bidirectional lead screw and the limiting rod, thereby adjusting the distance between the two clamping plates. This allows for the pressing and positioning of aerospace parts of different lengths at the top of the placement table, thus improving the applicability of the clamping device.

[0026] In use, the side connecting seat 17 is set so that the lower connecting plate 10 is positioned below the upper connecting plate 7;

Limiting rods 19 are fixedly installed on the inner walls of the side connecting seats 17 on both sides of the bidirectional lead screw 18. A clamping plate 11 is threaded on the outer wall on both sides of the bidirectional lead screw 18. The clamping plate 11 is movably connected to the limiting rod 19. The bottom end of the clamping plate 11 extends through to the bottom of the lower connecting plate 10.
