Abstract

The utility model discloses a clamp, which comprises a tray body and a rotation disc. Three radial sliding slots are arranged on the tray body from the center to the outside; a claw which can slide along the radial direction of the sliding slot is arranged in each sliding slot; the claw comprises a main body and a clamping part which extends upwards from the front end of the main body; the lower end of the main body is provided with threaded teeth; the rotation disc is rotatably arranged under the tray body; and the upper end is provided with plane threads which are engaged with the threaded teeth on the lower end of the main body. The clamp can adjust the position of the claw by rotating the rotation disc so as to clamp or fix the annular workpieces or similar workpieces with different sizes. Workpieces with different sizes can be fixed by using one clamp so the user can conveniently operate.

Description

A kind of anchor clamps

Technical field

The utility model relates to a kind of anchor clamps, refers in particular to a kind of anchor clamps that are used for fixing annular work piece.

Background technology

Annular work piece such as ring, bracelet etc. is being added man-hour, often needing to use anchor clamps fixing this workpiece, so that pattern-etching machine or manually its outer surface or inner surface are handled for example carving, frosted or the like.The anchor clamps of existing structure, the parts that are used for the clamping annular work piece that it is set are all unadjustable, and make at the anchor clamps that use the type fixedly during workpiece, annular work piece at different sizes, need select the anchor clamps of different size for use or change the parts that are used for this workpiece of clamping in the anchor clamps, could play the fixedly effect of workpiece ideally.

Summary of the invention

The purpose of this utility model is to overcome the existing existing defective of anchor clamps, and a kind of anchor clamps of the annular work piece applicable to the clamping different size are provided.

To achieve these goals, the utility model is by technical scheme as described below: a kind of anchor clamps include a disk body and a rotating disc, wherein, be outwards radial and be formed with three radial grooves on the described disk body from the center, be equipped with a claw that can radially slide along described chute in each chute, described claw includes the clamping part that a main part and a front end from described main part extend upward formation, and the place, lower surface of described main part is formed with ridge; Described rotating disc is located with the below that rotatable mode is arranged at described disk body, and its upper end surface forms flat thread, and described flat thread is meshed with the ridge at place, described main part lower surface.

In the above-mentioned anchor clamps, the lower surface of described disk body place is provided with a joint pin that passes described rotating disc, and described joint pin is connected in a connecting axle.

In the above-mentioned anchor clamps, the end of described connecting axle is formed with external screw thread.

In the above-mentioned anchor clamps, the angle between the two adjacent chutes is 120 degree.

In the above-mentioned anchor clamps, the two side of described chute place respectively is formed with a slide protrusion, and the place, two side of the main part of described claw respectively is formed with a sliding recess that is matched with described slide protrusion, and described slide protrusion is placed among the described sliding recess.

In the above-mentioned anchor clamps, the madial wall place of described clamping part is formed with horizontal anti-skidding recess.

The beneficial effects of the utility model are: these anchor clamps can be regulated the position of claw by rotating rotating disc, and with the annular work piece of different size or similar workpiece clamping or tensioning and play fixing effect, use same anchor clamps can grip the workpiece of different size, be convenient to user's operation.

Description of drawings

Fig. 1 is the decomposition texture schematic diagram of a kind of anchor clamps of the utility model.

The specific embodiment

For making those of ordinary skill in the art be expressly understood the purpose of this utility model, technical scheme and advantage more, the utility model is further elaborated below in conjunction with drawings and Examples.

Anchor clamps disclosed in the utility model can be used for the annular work piece clamping such as ring, the bracelet, so that the processing that pattern-etching machine or artificial surface within it or outer surface carry out such as car flower, polishing is handled, certainly, the workpiece that also can be used for clamping and annular work piece structure similar.With reference to figure 1, these anchor clamps include a disk body 10, are outwards radial and be formed with three radial grooves 100 from the center on this disk body 10, in this preferred embodiment, three chutes 100 are formed on this disk body 10 evenly and at intervals, that is, the angle between the two adjacent chutes 100 is 120 degree.Be equipped with a claw 101 that can radially slide along chute 100 in each chute 100, this claw 101 includes the clamping part 103 that a main part 102 and a front end from this main part 102 extend upward formation, the place, lower surface of this main part 102 is formed with ridge (not illustrating among the figure), by the mating reaction of three clamping parts 103, can be with annular work piece clamping and fixing.

The below that is positioned at this disk body 10 is sentenced rotatable mode and is provided with a rotating disc 11, the upper end surface of this rotating disc 11 forms flat thread (not illustrating among the figure), this flat thread is meshed with the ridge that is formed at place, main part 102 lower surfaces, so, by forwarding this rotating disc 11 to, then can drive claw 101 and move radially with respect to disk body 10 centers along chute 100.

Place, the lower surface of disk body 10 is provided with a joint pin 104 that passes described rotating disc 11, and this joint pin 104 is connected in a connecting axle 12, by this connecting axle 12 whole anchor clamps is fixed on the lathe.Be formed with external screw thread 120 in the end of connecting axle 12, and anchor clamps can be fixed on the lathe by the mode of being spirally connected.

The place, two side of this chute 100 respectively is formed with a slide protrusion 105, and the two side of the main part 102 of this claw 101 place respectively is formed with a sliding recess 106 that is matched with described slide protrusion 105, slide protrusion 105 is placed among the sliding recess 106, and plays the effect of further location claw 101.

During work, annular work piece to be processed is placed between the clamping part 103 of three claws 101, rotate rotating disc 11 and drive claw 101 and move towards the center of disk body 10, and with the annular work piece clamping, thereby can handle the inner surface of annular work piece.Preferably, the madial wall place of clamping part 103 is formed with horizontal anti-skidding recess 107, so that better play the effect that clamps annular work piece.Perhaps, annular work piece to be processed is placed in outside the clamping part 103 of three claws 101, rotates rotating disc 11 and drive claw 101 outward radials and move, and the annular work piece tensioning is fixed, thereby can handle the outer surface of annular work piece.

It can be seen from the above, regulate the position of claw 101 by rotating rotating disc 11, can be with the annular work piece of different size or similar workpiece clamping or tensioning and play fixing effect, use same anchor clamps can grip the workpiece of different size, be convenient to user's operation.

The above only is a preferred embodiment of the present utility model, but not the utility model is done any pro forma restriction.Those skilled in the art can impose various changes that are equal to and improvement on the basis of the foregoing description, all equivalent variations or modifications of being done in the claim scope all should fall within the utility model protection domain.
