Abstract

The utility model discloses a flexible butting mechanism for an automotive key and a lock cylinder. The flexible butting mechanism is characterized by comprising a spring housing with a rectangular inner cavity, wherein a tail end cover fixedly connected with the spring housing is connected with a driving shaft through a connecting block; a spring is arranged in the rectangular inner cavity of the spring housing, one end of the spring is propped against the tail end cover, and the other end of the spring is propped against a sliding block; the sliding block is in sliding fit in the rectangular inner cavity of the spring housing in a plunger form; an annular end cover is arranged at the front end of the spring housing, and the annular end cover using the inner circumference as a circle blocks the sliding block in the rectangular inner cavity of the spring housing; and a clamping block for clamping the key is fixedly connected with the sliding block through a switching block. The flexible butting mechanism is applied in a lock cylinder test process, and can meet the requirement for installation of the automotive key in the durability test state of the automotive lock cylinder and avoid damaging the lock cylinder in the test process.

Description

Automobile key and lock core flexible docking mechanism

Technical field

The utility model belongs to flexible docking mechanism, a kind of being applied in the automobile lock core process of the test of more specifically saying so, the flexible docking mechanism of well testing for automobile lock core.

Background technology

Automobile door lock is the critical product of protection automobile, and it not only influences the security of automobile, and the overall quality of automobile is also had certain influence.Because the quality of lockset quality has certain generality to the total quality of automobile to a certain extent.It is extremely important that the test of automobile lock core just becomes, especially long duration test, and lock core to carry out long duration test briefly be exactly that key inserts lockset and rotates and extract.When carrying out this test, if the key installation site slightly deviation will cause lock core to damage.Therefore install and accurately become a difficult problem.At present, in this process of the test, generally rely on testing crew to adopt manual adjustment to carry out.Mainly be slowly to attempt the installation site, constantly adjust the relative position of lock core and key.This adjustment is grasped by manual control fully, and just there is the adjustment error in this, and labor strength is big, and efficient is low.Moreover, owing to be rigid mechanism once adjustment has deviation will influence test findings, and then cause the damage of lock core.And the long duration test time is longer, and Key clamping-unit possibly have fine motion in process of the test, and this fine motion is uncertain, can cause that also lock core damages if this action surpasses lock core action tolerance.

Summary of the invention

The utility model is for avoiding above-mentioned existing in prior technology weak point; A kind of automobile key and lock core flexible docking mechanism are provided; It is applied in the Lock for automobile test; Simulate the insertion state of staff to a certain extent, alleviate the lock core that causes because of operating personnel's installation level and damage, thereby satisfy at the installation requirement of automobile lock core long duration test process to key.

The utility model adopts following technical scheme for the technical solution problem:

The design feature of the utility model automobile key and lock core flexible docking mechanism is that the spring housing with rectangular inner cavity is set; Be connected with driving shaft through contiguous block with the afterbody end cap that said spring housing connects firmly; Spring places the rectangular inner cavity of spring base; One end of said spring is butted on the afterbody end cap, and the other end is butted on slide block, and said slide block is that the form with plunger is slidingly fitted in the rectangular inner cavity of spring housing; Front end at said spring housing is provided with annular end cap, is that the annular end cap of circle is blocked in said slide block in the rectangular inner cavity of spring housing with interior week; The clamp that is used for the clamping key connects firmly through switching piece and slide block.

The design feature of the utility model automobile key and lock core flexible docking mechanism also be to transfer piece and slide block is an one-piece construction.

Compared with present technology, the utility model beneficial effect is embodied in:

1, the utility model can be simulated the insertion state of staff to a certain extent, alleviates the lock core that causes because of operating personnel's installation level and damages, and satisfies at the installation requirement of automobile lock core long duration test process to key.

2, the utility model is simple in structure, and it is little to take up room.

Label among the figure: 1 key; 2 clamps; 3 switching pieces; 4 slide blocks; 5 springs; 6 spring bases; 7 afterbody end caps; 8 contiguous blocks; 9 driving mechanisms; 10 annular end caps.

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3; Automobile key and lock core flexible docking mechanism are to be provided with the spring housing 6 with rectangular inner cavity in the present embodiment, are connected with driving shaft 9 through contiguous block 8 with the afterbody end cap 7 that spring housing 6 connects firmly, and spring 5 places the rectangular inner cavity of spring base 6; One end of spring 5 is butted on afterbody end cap 7; The other end is butted on slide block 4, and slide block 4 is rectangular blocks that the rectangular inner cavity of also spring housing 6 matches, and slide block 4 is slidingly fitted in the rectangular inner cavity of spring housing 6 with the form of plunger; Front end at spring housing 6 is provided with annular end cap 10, is that the annular end cap 10 of circle is blocked in slide block 4 in the rectangular inner cavity of spring housing 6 with interior week; The clamp 2 that is used for clamping key 1 connects firmly with slide block 4 through switching piece 3, and switching piece 3 is the right cylinders that are arranged in the annular end cap circle, and switching piece 3 shown in Figure 1 is an one-piece construction with slide block 4.

Straight line through driving mechanism 9 moves and rotates, and makes the key 1 that is clamped in the clamp front end be able to insert lock core and drive lock core to rotate.

Key 1 advances under the driving mechanism effect and near the lock core lockhole in this course, if key and lockhole are not exclusively identical, key can compression spring; Spring is compressed spring force and strengthens; Because the key front end has certain angle, can produce a component at stress point, this component can produce reacting force to key; Thus key is pushed lockhole, accomplish key and under thrusting action, adjust insertion position and the flexible process of inserting automatically.After being inserted into the position, under the driving mechanism effect, reverse, retreat again by turn-back after the execution and return.In the present embodiment; Spring housing through rectangular inner cavity is set obtains level of freedom on the different directions; Be implemented in the flexibility that advances and reverse two aspects; The size of acting force is by the decision of the decrement of spring, can use control that different springs or different strokes carry out power to reach the purpose of anthropomorphic dummy's skill degree or test dynamics.
