Abstract

The utility model discloses a manual four-jaw chuck with precise scales. The manual four-jaw chuck structurally comprises the precise scales, a chuck face, jaws, sliding chutes, rotating lead screws, a chuck body, a rear cover, scale lines and trapezoid threads, wherein the precise scales are processed on the chuck face of the four-jaw chuck, the scale lines are arranged on the jaws, the precise scales and the scale lines are matched to accurately confirm the positions of work pieces clamped by the chuck to improve accuracy, different precise scales can be designed according to the specifications of the clamped work pieces, four symmetrical sliding chutes which are arranged in the radial direction are processed on the chuck body, the chuck body diameters of different sizes and specifications can be designed according to the specifications of the clamped work pieces, the trapezoid threads meshed with the bottoms of the jaws are processed in the sliding chutes of the chuck body, and the jaws are in trapezoid thread fit with the rotating lead screws. By means of the precise scales processed on the chuck face, the clamping accuracy of the manual four-jaw chuck is improved. Meanwhile, the manual four-jaw chuck is easier to adjust and simple in work piece clamping operation and greatly improves work piece processing quality and accuracy. Furthermore, the processing efficiency is improved. The manual four-jaw chuck has great popularization value and is wide in application.

Description

Manual chuck with accurate scale

Technical field

The utility model relates to manual chuck, relates in particular to the manual chuck with accurate scale, belongs to the machining equipment field.

Background technology

But the four-jaw chuck of holding workpiece, it is the most important crucial clamping device of light-duty machinery process equipment or lathe, because this device single action is adjustable, easy to use, the client is vigorous to the market demand of independent chuck both at home and abroad, yet, because there is complex structure in existing four-jaw chuck, expensive, use to adjust the deficiencies such as difficulty, can not satisfying the market to the demand of the aspects such as the function of product, price, use.

China Patent No.: 200820113184.2 disclose a kind of four-jaw chuck, include disk body, bonnet, claw and screw mandrel, four claws are installed in the chute of four symmetries that radially arrange of disk body, be connected with respectively the screw mandrel that is meshed with the bottom of claw in each chute of disk body, be provided with rotary screw in the outer end of each screw mandrel to drive interior four jiaos of grooves of mobile usefulness in the chute of claw at disk body.Advantage is: it is mobile in the chute of disk body that the utility model drives claw with the interior four jiaos of groove fit on the outer four jiaos of spanners of plain edition and the screw mandrel, without special tool(s), can realize the four paws single action, simple to operate, easy to adjust.

But, existing manual chuck is when holding workpiece, be difficult for adjusting, clamp precision is very low, experience to the process operation personnel requires very high, general process operation person is difficult at short notice accurately with piece-holder, and precision is very low, not only affects the quality of processing but also greatly reduces working (machining) efficiency.

Summary of the invention

For overcome above existing apparatus technically with function on deficiency, the utility model proposes a kind of simple in structurely, with low cost, clamp precision is high, the easy to operate manual chuck with accurate scale.

The utility model solves existing issue by the following technical solutions.

With the manual chuck of accurate scale, structure comprises: accurate scale, card, claw, chute, rotating threaded shaft, disk body, bonnet, reticle, trapezoidal thread.

Be processed with accurate scale on the card of described chuck, be processed with reticle on the claw, accurate scale and reticle cooperate the position that can determine accurately the chuck holding workpiece, improve clamp precision; Specification size according to the clamping workpiece can design different accurate scales;

Be processed with the chute of four symmetries that radially arrange on the described disk body, be processed with respectively the trapezoidal thread that is meshed with the bottom of claw in each chute of disk body; According to the workpiece size of required clamping, can the different disk body diameter of design dimension specification;

It is mobile in the chute of disk body to drive claw that the outer end of described disk body is provided with rotary screw, the outside end face of rotating threaded shaft is interior four jiaos of grooves, with the interior four jiaos of groove fit on the outer four jiaos of spanners of plain edition and the rotating threaded shaft, it is mobile in the chute of disk body to drive claw, without special tool(s), can realize the four paws single action, simple to operate, easy to adjust;

Described claw and rotating threaded shaft are that trapezoidal thread cooperates; Bonnet is installed in the rear side of disk body.

The beneficial effects of the utility model: the manual chuck with accurate scale that the utility model proposes, employing is the design of processing precise scale in card, improved the clamp precision of manual chuck, simultaneously, so that the manually easier adjustment of chuck, the holding workpiece operation is simpler, has greatly improved quality and the precision of workpiece processing, improve simultaneously working (machining) efficiency, had very large promotional value and widely application.
