Abstract

The utility model discloses a rotating clamp. The rotating clamp comprises a clamp base and a clamp body, and is characterized in that the bottom of the body is connected with the base in rotating mode through a rotating shaft. The body comprises an upper locating rod, a lower locating rod and a connecting rod which is arranged between the upper and the lower locating rods and used to connect the upper and the lower locating rods, wherein two ends of the upper locating rod is respectively provided with screw holes along the vertical direction, a screw rod is arranged in the screw holes in penetrating mode, a clamp head is connected with the inner end head of the screw rod, and a handle is arranged on the outer end head of the screw rod. The rotating clamp can clamp a workpiece with two parallel planes conveniently, can rotate, and is convenient to use.

Description

A kind of rolling clamp

Technical field

The utility model relates to the rolling clamp that a kind of machine tooling is used.

Background technology

Be used for fixing processing object in the machine-building process, make it to be in correct position, the device to accept construction or to detect is referred to as anchor clamps, be called again jig, in a broad sense, any operation in technical process is used for rapidly, the device of convenient, safe installation workpiece, all can be described as anchor clamps, such as weld jig, inspection jig, assembling jig, jig etc., wherein jig is the most common, is called for short anchor clamps.On lathe during processing work, for the surface energy that makes workpiece reach the drawing regulation size, geometry and with other surperficial specification requirement such as relative-position error, workpiece must be installed (location) before the processing, clip (clamping).Anchor clamps are comprised of setting element (determining the tram of workpiece in anchor clamps), clamping device, tool setting induction element (determining relative position or the guiding tool orientation of cutter and workpiece), indexing means, Connection Element and clamp body (clamp base) etc. usually.

Anchor clamps can be divided into according to its handling characteristics: (1) universal anchor clamps, such as machine vice, chuck, sucker etc.; (2) specificity anchor clamps, commonly used have turning attachment, a fraise jig etc.; (3) flexible jig; (4) built-up jig.Anchor clamps often need to clamp have two plane-parallel workpiece in processing is used the time, in order to finish the process operations such as follow-up welding, boring, also do not have the clamping device of this special use at present.

Summary of the invention

The utility model purpose provides a kind of rolling clamp, uses this anchor clamps, can clamp easily to have two plane-parallel workpiece, and anchor clamps is rotatable, and is easy to use.

The technical solution of the utility model is: a kind of rolling clamp, comprise clamp base and chuck body, described body bottom is rotatably connected with described base through rotating shaft, described body comprises upper and lower backstay and is arranged at the connecting rod that connects upper and lower backstay between upper and lower backstay, described upper backstay two ends vertical direction offers respectively screw, run through being provided with screw rod in the described screw, described screw rod inner termination is connected with chuck, and described screw rod external end head is provided with handle.

Further technical scheme, described screw rod external end head laterally offers through hole, is provided with handle in the described through hole.

Further technical scheme, corresponding described clip position place is provided with cushion pad on the described lower backstay.

The utility model has the advantages that:

1. the utility model is by the chuck body that is rotatably connected at base, body is comprised of upper and lower backstay and connecting rod, upper backstay two ends are provided with screw rod and chuck, rotary screw is so that the chuck clamping work pieces, and because body is rotatable, and then can be easily the workpiece at anchor clamps two ends be carried out clamp operation;

2. the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the structural representation of the utility model embodiment one.

Wherein: 1, base; 2, body; 3, rotating shaft; 4, upper backstay; 5, lower backstay; 6, screw rod; 7, chuck; 8, handle; 9, cushion pad; 10, connecting rod.

The specific embodiment

Embodiment one: referring to shown in Figure 1, a kind of rolling clamp, comprise clamp base 1 and chuck body 2, described body 2 bottoms are rotatably connected with described base 1 through rotating shaft 3, described body comprises, lower backstay 4,5 and be arranged at, on connecting between lower backstay, the connecting rod 10 of lower backstay, described upper backstay 4 two ends vertical directions offer respectively screw, run through in the described screw and be provided with screw rod 6, described screw rod 6 inner termination are connected with chuck 7, described screw rod 6 external end heads are provided with handle 8, described screw rod 6 external end heads laterally offer through hole, are provided with handle 8 in the described through hole, and corresponding described clip position place is provided with cushion pad 9 on the described lower backstay 5.

Anchor clamps in use, workpiece to be processed is positioned on the lower backstay, operator grasps rotatable handle screw rod, the chuck elder generation clamping device one side workpiece thereby screw rod is rotated down, then rotating body, be rotated down by screw rod, chuck clamps the workpiece of opposite side again, and then finishes the clamping to body both sides workpiece.

The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
