Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a clamping tooling for aircraft parts. Background Art

[0002] Most aircraft parts are of irregular shapes. At present, a special clamping tool is usually configured for a certain part. In other words, the existing aircraft part clamping tool is not very versatile and practical, and cannot stably clamp parts of different regular shapes and sizes.

[0003] After searching, the application with patent number CN220593066U discloses a clamping tool for aircraft parts, including a workbench and two mounting plates. The back plate is provided with two sliding sleeves, and two columns are slidably inserted in the two sliding sleeves respectively. One of the mounting plates is fixedly installed on the front side of the back plate, and the other mounting plate is slidably installed on the front side of the back plate. The lifting drive assembly is installed between the back plate and the workbench, and the translation drive assembly is installed between the back plate and the movable mounting plate. A number of elastic telescopic rods are installed on the opposite surfaces of the two mounting plates. This can be suitable for aircraft parts of more sizes and has a wide range of applications.

[0004] However, due to the setting of the mounting plate and the elastic telescopic rod, the elastic telescopic rod is moved by the translation driving assembly, and the elastic telescopic rod clamps and fixes the parts, resulting in the parts shaking under the action of external force during the processing, and the clamping is unstable. At the same time, due to the setting of the elastic telescopic rod, the device can only clamp the left and right ends of the parts. When clamping flat parts, the parts can only be placed vertically for clamping, which is inconvenient and cannot clamp parts of various shapes, and has low practicality.

[0005] Therefore, we proposed a clamping fixture for aircraft parts. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a clamping tool for aircraft parts, which solves the problems of unstable clamping and low practicality of the prior devices.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: A clamping tool for aircraft parts, comprising a base, the bottom surface of which is fixedly mounted with four groups of support columns;

[0008] A support plate is mounted above the base, and threaded rods are fixedly mounted on the left and right ends of the top surface of the support plate respectively, and a sliding seat is slidably connected to the outer wall of the threaded rod, and two groups of stepper motors connected to the threaded rods are fixedly mounted on the bottom surface of the support plate, and an electric telescopic rod B is fixedly mounted on the inner side of the sliding seat, and a clamping plate is fixedly mounted on the telescopic end of the electric telescopic rod B;

[0009] The upper and lower sides of the clamping plate are equipped with fixed plates of matching specifications, three groups of telescopic rods with opposite positions are fixedly installed between the clamping plate and the fixed plate, telescopic springs are fixedly installed on the telescopic ends of the telescopic rods, a cylinder is fixedly installed on the inner side of the fixed plate, six groups of return springs with opposite positions are fixedly installed on the output end of the cylinder, and an extrusion block with matching specifications is fixedly installed on the bottom surface of the return spring.

[0010] Preferably, a rotating motor is fixedly mounted at the center of the top surface of the base, and the output end of the rotating motor is fixedly connected to the support plate, so that the clamped parts can be rotated, thereby facilitating the processing of the parts and improving the practicability of the device.

[0011] Preferably, a limiting plate with matching specifications is fixedly mounted on the top end of the threaded rod, so as to prevent the sliding seat from falling off the threaded rod.

[0012] Preferably, two sets of oppositely positioned electric telescopic rods A are fixedly mounted on the bottom surface of the support plate, and the telescopic ends of the electric telescopic rods A are located between the support plate and the sliding seat, which can improve the stability of the sliding seat in moving up and down.

[0013] Preferably, a rubber pad is fixedly installed on the inner side of the clamping plate, which can improve the clamping stability of the clamping plate and prevent the parts to be clamped from being damaged.

[0014] Preferably, pressure sensors are installed inside the extrusion block and the clamping plate to prevent damage to parts caused by excessive extrusion force.

[0015] 1. This clamping tool for aircraft parts is equipped with a threaded rod, a sliding seat and an electric telescopic rod B. According to the shape, size and center of gravity of the part, the sliding seat moves up and down on the threaded rod to a suitable position, and then the electric telescopic rod B drives the clamping plate to clamp and fix the part, which has high stability in clamping the part.

[0016] 2. At the same time, through the setting of the telescopic rod, the cylinder and the return spring, the distance between the two sets of fixing plates can be adjusted according to the height of the part, so that the cylinder is located on the upper and lower sides of the part, and then the cylinder drives multiple sets of extrusion blocks to clamp and fix the upper and lower sides of the part. Multiple sets of extrusion blocks and return springs can clamp various shapes, thereby improving the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
