Embodiment 1

[0031] See Figure 1 to Figure 7 , the present invention has a housing 1, a ball seat 2, a clamping ball 3, an inner sleeve 5, a positioning ball 8 and a ball locking mechanism; It has a spherical groove; the clamping balls 3 are respectively placed in at least three evenly distributed circular holes on the side wall of the ball seat 2; the inner sleeve 5 is sleeved on the outside of the clamping ball 3, and the inner sleeve 5 is provided with The groove matched with the clamping ball 3, the lower end surface of the inner sleeve 5 is in contact with the ball locking mechanism;

[0032] The ball locking mechanism includes a gear 4, a rack 6 and an electric push rod 7; the gear 4 is fixedly arranged on the outer surface of the ball seat 2, and the upper end surface of the gear 4 is in contact with the inner sleeve 5; the rack 6 meshes with the gear 4, and the rack 6 is connected to the push rod working end of the electric push rod 7; the fixed end of the electric push rod 7 is ...

Embodiment 2

[0036] See Figure 8 to Figure 14 , the present embodiment is basically similar to Embodiment 1, the difference is that the ball locking mechanism includes a first bevel gear 10, a second bevel gear 11 and a servo motor 7; the first bevel gear 10 is fixedly connected to the outer surface of the ball seat 2; The inner sleeve 5 is arranged above the first bevel gear 10 ; the second bevel gear 11 meshes with the first bevel gear 10 , and the second bevel gear 11 is connected with the rotating shaft of the servo motor 7 .

[0037] An observation window 12 is arranged on the side of the housing 1, through which the internal rotation can be observed and the locking situation can be judged.

[0038] The working principle of the present invention is: when the workpiece is positioned and supported, according to the external dimensions and weight of the workpiece, the positioning rods 9 are connected at multiple positions at the bottom of the workpiece, and the device is installed at th...

Abstract

The invention relates to an electric ball locking device for positioning and supporting. A shell, a ball base, clamping balls, an inner sleeve, a positioning ball and a ball locking mechanism are included. The ball base is inserted in the shell and fixed in the shell. A spherical surface groove is formed in an inner cavity of the ball base. The clamping balls are placed in at least three evenly-distributed circular holes in the side wall of the ball base. The inner sleeve is in cup joint to the outer sides of the clamping balls, the inner sleeve is provided with grooves matched with the clamping balls, and the lower end face of the inner sleeve makes contact with the ball locking mechanism. The positioning ball is matched with the spherical surface groove in the ball base, and the upper end of the positioning ball is connected with a positioning rod. The spherical surface contact manner is adopted in the electric ball locking device for locking, adaptive adjustment can be convenientlyconducted during workpiece clamping, the four clamping balls are used for locking, the positioning ball stress is balanced, and the locking effect is good.

Description

technical field [0001] The invention relates to a ball locking device, in particular to an electric ball locking device for positioning support. Background technique [0002] The traditional locking device mainly adopts unilateral pressing method to lock the ball, which leads to the unbalanced force on the positioning ball and affects the positioning accuracy, and after the locking is completed, the positioning locking ball is fixed, which is not easy to adapt sexual adjustment. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide an electric locking ball for positioning and support with a simple structure, which can ensure a balanced force on the positioning ball while locking the ball, and can be adaptively adjusted according to needs. device. [0004] The technical solution to realize the object of the present invention is: an electric ball locking device for positioning support, whic...
