Abstract

The utility model discloses an automatic clamping and releasing device which is composed of a clamping mechanism, a supporting stick, a clamping ring, a releasing ring and a connection block. The clamping mechanism, the clamping ring, the releasing ring and the connection block are sequentially arranged on the supporting stick, the clamping ring is fixedly arranged on the supporting stick, a groove which is used for the clamping mechanism for clamping is formed in the clamping ring, the groove and the releasing ring are correspondingly arranged, and the groove is matched with the releasing ring. The releasing ring is in sliding fit with the supporting stick, and the automatic clamping and releasing device can achieve automatic clamping and releasing by relying on a pure mechanical structure.

Description

A kind of device that clamps and releases automatically

Technical field

The utility model relates to a kind of chucking and release gear, and specifically a kind of have a device that clamps and releases function automatically.

Background technology

Clamp and release device in mechanical field, use very extensive, these devices are most rely on pneumatic, surge or electronicly realize clamping and releasing function as propulsion source.The anchor clamps even the manipulator that are come by these simple functions evolutions are extensive use of in every field.But in most cases, rely on mechanical external force and mechanical device to be difficult to accomplish the function that clamps and releases automatically merely.

The utility model content

Technical problem to be solved in the utility model provides a kind of device that clamps and releases automatically, can rely on pure physical construction to realize chucking and release automatically.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of device that clamps and releases automatically, by clamping body, support stick, clamping ring, discharging ring and contiguous block forms, clamping body, clamping ring, discharging ring and contiguous block is successively set on the support stick, clamping ring is fixedly installed on the support stick, on clamping ring, be provided with the groove that is used for the clamping body chucking, groove and the corresponding setting of release ring, and with discharge ring and be complementary, discharge ring and be bearing fit with support stick, described clamping body is by support, compression spring and a plurality of claw are formed, support and support stick are bearing fit, support is provided with claw, and claw is by compression spring and bolt and the hinged setting of support.

The beneficial effects of the utility model are: grasp device is an executive device, make it mobile by external force, spring is a compression spring, claw is initially gathers state, along with support moves down, the clamped ring of claw struts gradually, until arriving clamping ring lower end claw by spring pressure card master clamping ring, support rises then, finishes the chucking action.When needs discharge, support descends, claw is gathered once more, drops to when discharging ring to be strutted once more, arrives when discharging the ring lower end to gather, support rises, spring force makes the claw chucking discharge ring, and the release ring is followed support and risen, when rising to clamping ring, stop to rise in the groove of the first half embedding clamping ring of release ring, this moment, claw opened gradually until being released fully.So just finished the process that once relies on the motion of support merely and clamp and release.This kind device can be finished such as operations such as lifting, displacements at high-risk environment such as can't using manpower, aerodynamic force or the high temperature of the power of surging, high radiation easily.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Mark among the figure: 1, clamping body, 101, support, 102, compression spring, 103, claw, 2, support stick, 3, clamping ring, 4, discharge ring, 5, contiguous block, 6, groove.

The specific embodiment

As shown in the figure, a kind of device that clamps and releases automatically, form by clamping body 1, support stick 2, clamping ring 3, release ring 4 and contiguous block 5, clamping body 1, clamping ring 3, release ring 4 and contiguous block 5 are successively set on the support stick 2, clamping ring 3 is fixedly installed on the support stick 2, on clamping ring 3, be provided with the groove 6 that is used for clamping body 1 chucking, groove 6 and release ring 4 corresponding settings, and with discharge ring 4 and be complementary, discharge ring 4 and be bearing fit with support stick 2, described clamping body 1 is direct executive device, is driven by external force.Clamping body 1 is made up of support 101, compression spring 102 and a plurality of claw 103, support 101 is a cast iron, claw 103 is symmetrically distributed, support 101 is bearing fit with support stick 2, support 101 is provided with claw 103, support 101 provides the maintenance effect for claw 103, and claw 103 is by compression spring 102 and bolt and support 101 hinged settings.

Described contiguous block 5 is used for institute's mobile object and connects use, and contiguous block and cylindrical rod can be as a whole, but also disassemble installs and fixes.

As the mobile object of need, then on object, fix contiguous block 5 in advance.Support 101 from top to bottom moves together with claw 103 and compression spring 102, and when claw 103 was run into clamping ring 3 upper surfaces, claw 103 began to open, and when claw 103 arrives clamping ring 3 bottom surfaces, realizes clamping under the application force of compression spring 102.The movement of objects that support 101 moves needs thereby can move up this moment is to assigned address.After the object that need move had been assigned address, support 101 continued to fall, and ran into when claw 103 and opened once more when release encircles 4, and until sliding into the downside that discharges ring 4, claw 103 is realized chucking once more.Support 101 begins to rise, and is movable part owing to discharge ring 4, rises together so follow claw 103.Stop to rise in the time of in discharging the groove 6 that ring 4 rises to clamping ring 3, claw 103 continues rising along the inclined-plane that discharges ring 4, breaks away from fully thereby cross clamping ring 3.So just having finished the action that once clamps and releases, is to finish fully voluntarily and clamp and release, and need not extra propulsion source.
