Description

Novel sliding mechanism with quick locking function

Technical Field

The utility model relates to a car examines utensil trade and all kinds of station utensil trades, particularly relates to a novel glide machanism that has quick locking.

Background

With the rapid development of the automobile industry and the acceleration of the updating of automobile models, a host factory has further requirements on the shortening of the development period and the effective control of the cost, the requirement on the measurement of products on the checking fixture is high, the cost is effectively reduced, and the locking is generally performed by using a bolt after the products slide to corresponding positions in the market at present (as shown in figure 1), so that the use efficiency of the checking fixture is greatly reduced. Secondly bolt mode locking can cause the phenomenon of plug difficulty receiving under certain external force, and the machining form that the glide machanism's on the existing market base adopted cuts on the monoblock raw materials in addition, and the material is extravagant serious like this, and the processing cost is high moreover, and machining efficiency is lower.

SUMMERY OF THE UTILITY MODEL

The problem of the product use bolt side location and locking inefficiency on examining the utensil at present, lead to installation check out time slower, the bolt is detained when using and the seat base is the cutting processing on the monoblock steel part in the past, the cost of manufacture is high is solved.

The utility model aims at providing a novel sliding mechanism with quick locking, which comprises a handle ball, a cam shaft, a base, a positioning block and a sliding rod, wherein the far end of the sliding rod is provided with a through groove, and the two sides of the through groove are respectively provided with a first waist-shaped hole and a second waist-shaped hole; the first waist-shaped hole and the second waist-shaped hole are respectively provided with a first groove and a second groove, the camshaft consists of a cam, a shaft neck and a fixed shaft, a handle ball is fixed on the shaft neck of the camshaft, the right lower end of the cam of the camshaft is provided with an eccentric through hole, the fixed shaft penetrates through the eccentric through hole, and two ends of the fixed shaft are mutually matched and connected with the first groove and the second groove; the handle ball is pushed, and the cam shaft, the first groove and the second groove are sleeved in the through groove through the fixed shaft to eccentrically rotate; the base is provided with a convex notch, the sliding rod is sleeved with the base through the convex notch, the handle ball is rotated, and the sliding rod is driven by the cam shaft to slide in the convex notch; a positioning block is fixed at the tail end of the sliding rod; the base is designed to be in an inverted T shape, screw holes are formed in steps on two sides of the base, a first clamping hole and a second clamping hole are formed in the left end of the convex notch, a third clamping hole is formed in the right end of the convex notch, one end of the fixed shaft extends into the first clamping hole, and the other end of the fixed shaft extends into the third clamping hole; the automatic spring pin is connected with the base through the second clamping hole.

The sliding rod is a T-shaped rod and comprises a sliding rod and a clamping block, and a positioning screw hole is formed in the clamping block.

In order to further solve the locking inefficiency, lead to installing the problem that the check-out time is slower and the bolt is retardant when using, this scheme is as follows: the top and the bottom openings of the through groove are all set to be rectangular, and the first waist-shaped hole and the second waist-shaped hole at the two ends of the through groove are identical in size and shape. For the sliding range of cooperation slide bar, lead to the motion range restriction of groove to the camshaft for the rotary motion time of camshaft shortens, has improved locking efficiency, has accelerated the time that the installation detected, and leads to the groove and the cooperation use of camshaft has not had the retardation.

When the automatic spring pin rotates, the head of the pin rod of the automatic spring pin can automatically spring into the waist-shaped hole to clamp the camshaft or be pressed into the pin body, and no stagnation exists during use.

In order to further solve the locking inefficiency, lead to installing the problem that the check-out time is slower and the bolt is retardant when using, this scheme is as follows: the first clamping hole and the third clamping hole are on the same horizontal line, the handle ball is pushed clockwise, the cam shaft rotates clockwise along the fixed shaft to lift up, the sliding rod is driven to slide until the cam shaft is clamped by the pin rod popped out by the recovered automatic spring pin, and the sliding mechanism is opened; anticlockwise promote the handle ball, the camshaft lifts along fixed axle anticlockwise rotation, drives the pole slip that slides, inside the chucking pin rod was impressed automatic spring catch again by the pole that slides, the terminal of pin rod takes place to misplace with the spring pin body and moves backward, closes glide machanism promptly. The camshaft drives the sliding rod to be matched and connected with the waist-shaped hole and the automatic spring pin, so that the locking can be performed quickly, the locking efficiency is improved, the detection time is shortened, and no stagnation exists during use.

In order to further solve the locking inefficiency, lead to the slower problem of installation check-out time, this scheme is as follows: the width of the through groove is larger than that of a shaft neck of the camshaft, and the length of the through groove is larger than the diameter of the cam.

In order to further solve the locking inefficiency, lead to the slower problem of installation check-out time, this scheme is as follows: the opening width of the top end of the convex groove is larger than the width of a shaft neck of the camshaft. The cam shaft does eccentric rotation motion in the convex groove, so that locking can be realized quickly, and detection time is saved.

The utility model has the advantages that: the utility model discloses it is fast to have the locking installation, can not have retardant phenomenon, long service life and low in manufacturing cost's advantage.
