Description

Cam handle type locker

Technical Field

The utility model relates to a play quick locking and the cam handle type locker of the effect of loosening in the automated manufacturing field.

Background

At present, the well-known device that can play locking effect to frock mould is generally the screw, but under the condition that needs quick frock, quick mould that trades, uses the screw, when the dismouting, just will spend longer time, must lead to the production line to stop the line for a long time to extravagant a large amount of shut down stop line time, reduced production facility's production utilization ratio by a wide margin.

Disclosure of Invention

In the switching frock in-process of production line, in order to reduce the time of stopping the line, realize quick switching frock, mould, the utility model provides a cam handle type locker is fixed in the body above the frock mould that needs to be changed, on being fixed in the workstation of equipment with the lock sleeve (otherwise fix also can), can realize the locking of body and lock sleeve and loosen through pulling the cam handle to the direction of difference to realize the fast switch-over of frock.

The utility model discloses realize locking fast and loosen the design that the function adopted and be: the cam handle is pulled manually, the cam surface on the cam handle and the upper pressing pin are controlled to be in a pressing state or a free state, so that compression and rebound of the disc spring are controlled, upward and upward movement of the lower pressing pin is controlled under the matching action of the rectangular spring, upward and downward movement of the main steel ball is controlled, and finally forward and backward movement of the auxiliary steel ball is realized, so that locking and unlocking of the auxiliary steel ball and the locking sleeve which are installed on the body are realized, and locking and unlocking between the body and the locking sleeve are realized.

The utility model has the advantages that the locking mechanism consists of a body, a rotating shaft, a cam handle, a stop pin, an upper pressure pin, a linear spring, a disc spring, a rectangular spring, a lower pressure pin, a locking sleeve, a main steel ball, an auxiliary steel ball, an end cap and a snap ring, wherein the cam handle is manually pulled to turn to a locking side; on the contrary, when the cam handle is rotated to the loosening side, the upper pressing pin and the disc spring are in a free state, the lower pressing pin rebounds upwards under the action of the rectangular spring, the main steel ball is in the free state at the moment, and the auxiliary steel ball moves inwards in space to realize the unlocking of the body and the locking sleeve.

Drawings

The invention will be further described with reference to the following description and specific examples, which are given in conjunction with the accompanying drawings:

fig. 1 is a longitudinal sectional view of the present invention (the cam surface of the cam handle compresses the upper pressing pin, and the auxiliary steel ball and the locking sleeve are in a locking state).

Fig. 2 is a longitudinal sectional view of the present invention (the cam handle and the upper pressing pin are in a free state, and the auxiliary steel ball and the locking sleeve are in an unlocked state).

Fig. 3 is an isometric view of the present invention (showing the cam handle assembled with the other components).

In the figure, 1, a body, 2, a rotating shaft, 3, a cam handle, 4, a stop pin, 5, an upper pressing pin, 6, a linear spring, 7, a disc spring,

8. the device comprises a rectangular spring, 9 a lower press pin, 10 a locking sleeve, 11 a main steel ball, 12 an auxiliary steel ball, 13 a plug and 14 a snap ring.

Detailed Description

In the figure 1, a cam handle (3) is arranged on a body (1) through a rotating shaft (2) and a stop pin (4), at the moment, a cam surface on the cam handle is pressed on an upper pressing pin (5), so that the upper pressing pin (5) presses a disc spring (7) to deform the disc spring, thrust generated by deformation of the disc spring (7) overcomes the resistance of a rectangular spring (8) and then pushes a lower pressing pin (9) to move downwards, the lower pressing pin (9) pushes a main steel ball (11) to move downwards, the main steel ball (11) pushes an auxiliary steel ball (12) to move outwards, the auxiliary steel ball (12) is pressed on a conical surface of a locking sleeve (10), so that locking between the auxiliary steel ball (12) and the locking sleeve (10) is achieved, and locking between the body (1) and the locking sleeve (10) is finally achieved. The mounting hole of the auxiliary steel ball (12) on the body (1) is small at the opening part and large at the inner side, so that the auxiliary steel ball (12) cannot fall outwards. The plug (13) and the snap ring (14) are arranged at the opening of the body (1) to prevent the auxiliary steel ball (12) from falling off from the inside.

In fig. 2, a cross-sectional view of the unlocked state is shown: the cam handle (3) is pulled to the unlocking side, the cam surface and the upper pressing pin (5) are in a free separation state, the disc spring (7) is also in a free state, and the lower pressing pin (9) rebounds upwards under the action of the rectangular spring (8) at the moment, so that the main steel ball (11) is in the free state, the auxiliary steel ball (12) slides inwards in space, and the unlocking of the auxiliary steel ball (12) and the locking sleeve (10) is achieved.

In fig. 3, the cam handle (3) is mounted in a groove on the body (1) through the rotating shaft (2), the rotating shaft (2) is a stepped shaft with a thin middle and thick two ends, and the stop pin (4) is always in a bounce state and clamped in the rotating shaft (2) under the action of the linear spring (6) so as to ensure that the cam handle (3) is always mounted on the body (1) through the rotating shaft (2) and does not fall off.
