Embodiment 1

[0028] The main structure of this embodiment, such as figure 1 , figure 2 As shown, it includes the lower base 1 and the upper end cover 6, the end cover 6 is provided with a rotating disc 3, and the middle part of the end cover 6 and the rotating disc 3 is provided with a through hole for the ball head 7 to be inserted into. The upper surface of the disk 3 is also provided with a ball-holding device; the side of the end cover 6 is provided with a number of positioning holes with different functions, and the positioning holes are connected through through grooves; The handle 8 of the hole, the handle 8 can be rotated in the positioning hole of different functions, and drives the ball head holding device on the upper part of the rotating disk 3, so as to realize the different positioning of the ball head 7 inserted into the end cap 6 and the rotating disk 3. GPS.

[0029] The specific implementation is that the ball head holding device has three states: loosening, escape pre...

Embodiment 2

[0034] On the basis of the above-mentioned embodiments, this embodiment further defines the structure of the ball head device, such as figure 1 As shown, the ball head holding device provided on the upper surface of the rotating disk 3 is mainly composed of three sets of clamping mechanisms, and each set of clamping mechanisms is composed of a lower guide block 4 and an upper ball head holding block 5. The upper surface of the rotating disc 3 is provided with three mutually disconnected oblique chute 302, each oblique chute 302 is provided with a guide block 4, and the side of the end cover 6 is evenly distributed with The guide hole 601 matched with the ball joint clamping block 5, one end of each ball joint clamping block 5 is placed in the guide hole 601, and the other end faces the through hole in the middle of the end cover 6, between the adjacent ball joint clamping blocks 5 The angle between them is 120°. When the handle 8 drives the rotating disk 3 to rotate, it drive...

Embodiment 3

[0036]On the basis of the above-mentioned embodiments, this embodiment further defines the structure of the guide block 4 and the ball head holding block 5, such as figure 1 As shown, each of the guide blocks 4 includes a lower slide block and an upper fixed column, and each of the ball head clamping blocks 5 is provided with a blind hole that is sleeved on the upper fixed column of the guide block 4, and each ball head The end surfaces of the clamping block 5 facing the through hole in the middle of the end cover 6 are spherical contours 501 . Since the end surface of the ball head holding block 5 is set to the spherical profile 501 to clamp the ball head 7, it is set to the spherical profile 501, and since one end of the ball head holding block 5 is placed in the guide hole 601, there is no need to fix the guide block 4 With the ball head holding block 5, the fixed column at the top of the guide block 4 and the blind hole at the bottom of the ball head holding block 5 can be...

Abstract

The invention discloses a radial direct-acting type clamping device. The radial direct-acting type clamping device comprises a base on the lower portion and an end cover on the upper portion, a rotating disc is arranged in the end cover, through holes allowing ball heads to be inserted are formed in the middle of the end cover and the middle of the rotating disc, and a ball head holding device is further arranged on the upper surface of the rotating disc; and the side edge of the end cover is provided with a plurality of positioning holes with different functions, the positioning holes communicate with one another through through grooves, the side edge of the rotating disc is further provided with a handle penetrating through the positioning holes of the end cover, and the handle can rotate in the positioning holes with different functions and drive the ball head holding device on the upper portion of the rotating disc, so that different positioning functions on the ball heads inserted into the end cover and the rotating disc are realized. When the clamping device is used in cooperation with a numerical control positioner, efficient and accurate positioning and effective locking of parts can be achieved, the time for posture adjustment and butt joint assembly of large aircraft parts is shortened to a certain degree, and compared with a hydraulic or pneumatic ball head clamping device, the clamping device is safer and more reliable, simple in structure, convenient to operate and suitable for wide application and popularization.

Description

technical field [0001] The invention relates to the technical field of aviation special equipment manufacturing, in particular to a radial direct-acting clamping device. Background technique [0002] In the field of aircraft manufacturing, due to the complex structure, large size and irregular shape of the aircraft, in the assembly process, the complete product is often formed by docking various large components. Due to the large structure of the aircraft, a large movement space is required during the assembly process and a high position adjustment accuracy must be ensured in real time before and after the docking, so as to meet the smooth docking of the fuselage. [0003] Nowadays, in aircraft manufacturing, CNC positioners are used more and more widely. Usually, the docking assembly of aircraft components is realized by certain tooling and CNC positioners. Low, long assembly time. Contents of the invention [0004] The object of the present invention is to provide a ra...
