Description
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.

The specific embodiment
Newly be described further originally practical below with reference to accompanying drawing.
Such as Fig. 1, shown in Figure 2, with the manual chuck of accurate scale, structure comprises: accurate scale 1, card 2, claw 3, chute 4, rotating threaded shaft 5, disk body 6, bonnet 7, reticle 8, trapezoidal thread 9.
Such as Fig. 1, shown in Figure 5, be processed with accurate scale 1 on the card 2 of chuck, 3 are processed with reticle 8 on the claw, and accurate scale 1 and reticle 8 cooperate the position that can determine accurately the chuck holding workpiece, improve clamp precision;
As shown in Figure 2, be processed with the chute 4 of four symmetries that radially arrange on the disk body 6, each chute 4 interior trapezoidal thread 9 that are meshed with the bottom of claw 3 that are processed with respectively of disk body 6;
As shown in Figure 2, it is mobile in the chute of disk body to drive claw that the outer end of disk body 6 is provided with rotary screw 5, the outside end face of rotating threaded shaft 5 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, drive claw 3 in the chute 4 interior movements of disk body 6, without special tool(s), can realize the four paws single action, simple to operate, easy to adjust;
As shown in Figure 4, claw 3 and rotating threaded shaft 5 are that trapezoidal thread cooperates; As shown in Figure 3, bonnet is installed in the rear side of disk body.
