Description

Pneumatic lock ball clamping system

technical field

The invention relates to a clamping mechanism, in particular to a pneumatic locking ball clamping system.

Background technique

At present, the clamping force of the mechanism for mechanically clamping workpieces is relatively small, and there is no design for increasing force through transmission parts, and the form is single.

Contents of the invention

The object of the present invention is to provide a safe and reliable pneumatic locking ball clamping system with simple structure, flexible and convenient movement, and the support disc supporting the workpiece can be tilted according to needs, so as to overcome the shortcomings of the prior art.

The pneumatic locking ball clamping system of the present invention includes a cylinder body, a piston is arranged inside the cylinder body, an upper sleeve body and an upper cover are fixedly connected above the cylinder body, and a supporting steel ball is arranged on the cylinder body at the center of the piston to support The steel ball is connected with a support rod, and the upper end of the support rod protrudes from the upper cover and connects to the support plate. There is a locking steel ball hole on the upper side of the center of the supporting steel ball on the cylinder body. The locking steel ball hole A locking steel ball is arranged inside, and an inner tapered surface matched with the locking steel ball is arranged on the piston. The upper chamber of the piston is connected with an upper air nozzle, and the lower chamber of the piston is connected with a lower air nozzle.

In the pneumatic locking ball clamping system of the present invention, when in use, the workpiece is fixedly connected to the support plate, and the piston is driven to move upward through the pneumatic control device, that is, the lower cavity is fed into the air, the upper cavity is exhausted, and the inner cone surface on the piston is pressed against Lock the steel ball, make the locking steel ball press against the support steel ball, lock the support steel ball and the cylinder body relatively, and lock the support rod, the support plate and the workpiece at the same time. If it is necessary to tilt the workpiece at a certain angle, in the locked state, the supporting steel ball will rotate a certain amount relative to the cylinder body, and the workpiece will deflect accordingly. The utility model has the advantages of simple structure, flexible and convenient action, and the support plate supporting the work can be tilted according to needs, and is safe and reliable.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the present invention;

FIG. 2 is a schematic top view of FIG. 1 .

Detailed ways

As shown in Figures 1 and 2: 1 is a cylinder body, a piston 2 is arranged inside the cylinder body 1, and an upper sleeve body 6 and a loam cake 7 are fixedly connected above the cylinder body 1 . The inner center of the cylinder body 1 is processed with an inner spherical surface, and the inner spherical surface of the cylinder body 1 at the center of the piston 2 is equipped with a supporting steel ball 13, and the supporting steel ball 13 can rotate in the inner spherical surface. A support rod 9 is connected above the support steel ball 13, and the support rod 9 and the support steel ball 13 are connected by screws 12. The upper end of the support rod 9 protrudes from the central hole of the upper cover 7 and is connected to the support plate 8, and the support plate 8 and the support rod 9 are integrally structured. A plurality of locking steel ball holes are distributed in the circumferential direction on the upper side of the center of the supporting steel ball 13 on the cylinder body 1, and each locking steel ball hole is equipped with a locking steel ball 5, which is processed on the piston 2 There is an inner tapered surface 17 matched with the locking steel ball 5, and the upper chamber 3 of the piston 2 communicates with an upper air nozzle 4, which is threadedly connected to the upper sleeve body 6. The lower chamber 15 of the piston 2 is communicated with a lower air nozzle 16, and the lower air nozzle 16 is threadedly connected to the cylinder body 1. An upper sealing ring 11 is arranged between the piston 2 and the upper casing 6 , and a lower sealing ring 14 is arranged between the piston 2 and the cylinder body 1 .

When in use, the workpiece is fixedly connected to the support plate 8, and the piston 2 is driven to move upward through the pneumatic control device, that is, the lower chamber 15 intakes air, the upper chamber 3 exhausts, and the inner tapered surface 17 on the piston 2 presses against the locking steel ball 5. Make the locking steel ball 5 press against the supporting steel ball 13, lock the supporting steel ball 13 relative to the cylinder body 1, and lock the supporting rod 9, the supporting plate 8 and the workpiece at the same time. If it is necessary to tilt the workpiece at a certain angle, the support plate 8 can be pushed to make the support steel ball 13 rotate to a certain extent relative to the cylinder body 1, and the workpiece will deflect accordingly, and then locked by the pneumatic control device. The utility model has the advantages of simple structure, flexible and convenient action, and the support plate supporting the work can be tilted according to needs, and is safe and reliable.
