Abstract
The utility model relates to a fine-turning clamping claw device. The fine-turning clamping device comprises a clamping disk, wherein three clamping claws are arranged on the installation end surface of the clamping disk around the center of the clamping disk at equal intervals and the three clamping claws are used for clamping a workpiece. The fine-tuning clamping claw device is characterized in that an open groove is formed in one side of each clamping claw, the side of each clamping claw is close to the workpiece, the opening groove is perpendicular to the installation end surface of the clamping disk, a threaded hole which is perpendicular to the open groove is formed in the other side of each clamping claw, the other side of each clamping claw is far away from the workpiece, the bottom of the threaded hole is communicated with the open groove, a fine-turning screw nail is arranged in the threaded hole, and the fine-turning screw nail penetrates through one side of the open groove and abuts against the other side of the open groove. The clamping claws are respectively fixed on the clamping disk through fastening screw nails. The fine-turning clamping claw device can effectively and reliably fix the workpiece and greatly improve stability of processing quality. In addition, the fine-turning clamping claw device can effectively and fine adjust jump of clamping claw clamping positions and enable the clamping claw clamping positions to meet requirements. The fine-turning clamping claw device has the advantages of facilitating clamp, greatly improving work efficiency due to the fact that clamping can be finished at one time, and being wide in application range and long in service life due to the fact that no sliding friction exists.
Description
Technical field
The utility model relates to a kind of claw, and especially a kind of fine-tuning jaw means belongs to machining manufacturing equipment technical field.
Background technology
Use three-jaw self-centering chuck on numerically controlled lathe, the clamping place requirement of beating is very high.In prior art, claw can not be regulated, and by the senior skilled worker, claw is carried out the right boring correction, it is beated dwindle again and again, and is quite time-consuming and beat and exist all the time.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of fine-tuning jaw means is provided, when using three-jaw self-centering chuck on numerically controlled lathe, beat requirement when very high when clamping place, the handled easily work the shortest time of utilization is adjusted; And can be effectively, clamping workpiece reliably.
According to the technical scheme that the utility model provides, described fine-tuning jaw means comprises chuck, equidistant round the center of chuck on the installation end face of chuck three claws that are used for holding workpiece is set; It is characterized in that: the side at the close workpiece of described claw arranges open slot, and this open slot is perpendicular to the installation end face of chuck; Away from a side setting of the workpiece screwed hole perpendicular to open slot, the bottom of this screwed hole is communicated with open slot, at screwed hole, micrometer adjusting screw is set on described claw, and micrometer adjusting screw passes a side of open slot and withstands the opposite side of open slot.
Described claw is fixed on chuck by trip bolt respectively.
The utlity model has following advantage: (1) the utility model can be effectively, fixation workpiece reliably, greatly improves the stability of crudy; (2) the utility model can be finely tuned beating of claw clamping place effectively, and it is met the requirements; (3) the utility model clamping is convenient, and basic clamped one time is completed, and greatly increases work efficiency; (4) the utility model scope of application is wider, and fricton-tight friction, and the life-span is longer; (5) the utility model is simple in structure, and manufacturing cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 1: described fine-tuning jaw means comprises chuck 1, claw 2, micrometer adjusting screw 3, trip bolt 4, workpiece 5, open slot 6 etc.
As shown in Figure 1, the utility model comprises chuck 1, this chuck 1 is three-jaw self-centering chuck, equidistant round the center of chuck 1 on the installation end face of chuck 1 three claws 2 that are used for holding workpiece 5 is set, and claw 2 is fixed on chuck 1 by trip bolt 4 respectively; A side at described claw 2 close workpiece 5 arranges open slot 6, and this open slot 6 is perpendicular to the installation end face of chuck 1; Away from a side setting of workpiece 5 screwed hole perpendicular to open slot 6, the bottom of this screwed hole is communicated with open slot, at screwed hole, micrometer adjusting screw 3 is set on described claw 2, and micrometer adjusting screw 3 passes a sidepiece of open slot 6 and withstands the opposite side of open slot 6.
Operation principle of the present utility model: the utility model is provided with open slot 6 in the front portion of claw 2, and connect along vertical brill one screwed hole and the open slot 6 of open slot 6, be screwed into micrometer adjusting screw people 3 in screwed hole, the end of micrometer adjusting screw 3 is passed a side of open slot 6 and is withstood the opposite side of open slot 6; Turn gently micrometer adjusting screw 3, centering clamping place is beated, and it is met the requirements; Must be noted that amount trimmed is little, in order to avoid claw generation permanent deformation.The utility model adopts adjustment screw 3 to produce ejecting force, and in conjunction with the open slot 6 on claw 2, makes claw 2 produce trace and radially change, thereby realize beating of fine setting claw clamping place.The utility model handled easily work the shortest time of utilization is adjusted, can be effectively and clamping workpiece reliably, and can finely tune clamping place and beat.
Claims (2)
