Description
Technical field
This utility model belongs to machine tool accessory technical field, relates to a kind of claw, the particularly claw of a kind of novel scroll chuck.
Background technology
Scroll chuck is made up of chuck body, movable jaw and claw driving mechanism. On scroll chuck below three claw targeting parts, screw thread is had to be meshed with the flat thread at the dish bevel gear back side, when rotating cone pinion with spanner by four square holes, dish pinion rotation, the flat thread at the back side drives three claws close to center simultaneously or exits, in order to clamp the workpiece of different-diameter. It is used on three claws and changes three anti-pawls, be used for the workpiece being relatively large in diameter is installed.
Chuck is divided into hand chuck and power chuck two kinds by power difference used by driving claw. Hand chuck is general-purpose accessory, the conventional chuck having self centering scroll chuck and each claw individually to move. Scroll chuck is driven bevel gear wheel by bevel pinion. Bevel gear wheel be backed with archimedean spiral groove, be meshed with 3 claws. Therefore rotate bevel pinion with spanner just can make 3 claws move radially simultaneously, it is achieved self-centering and clamping are suitable to clamp the workpiece of circular equilateral triangle or regular hexagon etc. But the claw of common chuck is generally just with the metal material integrative-structure of rigidity, because when the workpiece that grip strength is relatively low, it is easy to piece-holder deformed.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that the claw of a kind of novel scroll chuck with buffering protection function.
The purpose of this utility model can be realized by following technical proposal: the claw of a kind of novel scroll chuck, including body, it is characterized in that, the side of described body is connected with against block, the side of described body is provided with installing hole, described the inner against block is embedded in described installing hole, the described outer end against block stretches out in the lateral wall of described body, be provided with spring in described installing hole, the two ends of described spring bear against described against block with on described body.
When clamping workpiece, claw moves the sidepiece making to be resisted against workpiece against block, it is achieved the clamping to workpiece. In the process of clamping workpiece, when chucking power incrementally increases, when the external force received against block is more than the elastic force of spring, promote spring toward internal mobile against block, it is to avoid to crush workpiece because of clamping force, play the function of buffer protection.
In the claw of above-mentioned a kind of novel scroll chuck, described includes the connecting portion in column against block and is threaded in the butting section of connecting portion one end, and described spring housing is located at the outside of described connecting portion. Spring housing is located at the outside of connecting portion, and spring has good locating effect.
In the claw of above-mentioned a kind of novel scroll chuck, the sidewall of described installing hole is provided with gathering sill, described gathering sill is parallel to the axially arranged of described installing hole, and the sidepiece of described connecting portion is vertically provided with lead, and described lead is embedded on described gathering sill. It is embedded in gathering sill by lead, makes the alternating translational against block have good guide effect.
In the claw of above-mentioned a kind of novel scroll chuck, the lateral wall of described butting section is enclosed with one layer of buffer body. The lateral wall of butting section is enclosed with one layer of buffer body, during clamping workpiece, has the function playing buffer protection.
In the claw of above-mentioned a kind of novel scroll chuck, described buffer body is elastomeric material, and the thickness of described buffer body is 2mm-4mm.
In the claw of above-mentioned a kind of novel scroll chuck, the lateral wall of described butting section has zigzag rubbing surface. By arranging rubbing surface, buffer body is made to be connected comparatively firmly advantage with butting section.
Compared with prior art, the claw of this kind of novel scroll chuck has the advantage that
1, in the process of clamping workpiece, when chucking power incrementally increases, when the external force received against block is more than the elastic force of spring, promote spring toward internal mobile against block, it is to avoid to crush workpiece because of clamping force, play the function of buffer protection;
2, spring housing is located at the outside of connecting portion, and spring has good locating effect;
3, it is embedded in gathering sill by lead, makes the alternating translational against block have good guide effect;
4, the lateral wall of butting section is enclosed with one layer of buffer body, during clamping workpiece, has the function playing buffer protection.

In figure, 1, body; 1a, installing hole; 1b, gathering sill; 2, against block; 2a, connecting portion; 2b, butting section; 2c, lead; 3, spring; 4, buffer body; 5, end cap.
Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As shown in Figure 1, a kind of claw of novel scroll chuck, including body 1, the side of body 1 is connected with against block 2, the side of body 1 is provided with installing hole 1a, and the inner against block 2 is embedded in installing hole 1a, and the outer end against block 2 stretches out in the lateral wall of described body 1, being provided with spring 3 in installing hole 1a, the two ends of spring 3 bear against on block 2 and body 1. Including the connecting portion 2a in column against block 2 and be arranged on the butting section 2b of connecting portion 2a one end, spring 3 is set in the outside of connecting portion 2a. The sidewall of installing hole 1a is provided with gathering sill 1b, gathering sill 1b and is parallel to the axially arranged of installing hole 1a, and the sidepiece of connecting portion 2a is vertically provided with lead 2c, and lead 2c is embedded on gathering sill 1b. The outer end of installing hole 1a is threaded end cap 5, connecting portion 2a traverse end cap 5.
The lateral wall of butting section 2b has zigzag rubbing surface, by arranging rubbing surface, makes buffer body 4 be connected comparatively firmly advantage with butting section 2b.The lateral wall of butting section 2b is enclosed with one layer of buffer body 4, and buffer body 4 is elastomeric material, and the thickness of buffer body 4 is 2mm-4mm. The lateral wall of butting section 2b is enclosed with one layer of buffer body 4, during clamping workpiece, has the function playing buffer protection.
When clamping workpiece, claw moves the sidepiece making to be resisted against workpiece against block 2, it is achieved the clamping to workpiece. In the process of clamping workpiece, when chucking power incrementally increases, when the external force received against block 2 is more than the elastic force of spring 3, promote spring 3 toward internal mobile against block 2, it is to avoid to crush workpiece because of clamping force, play the function of buffer protection. Spring 3 is set in the outside of connecting portion 2a, and spring 3 is had good locating effect. It is embedded in gathering sill 1b by lead 2c, makes the alternating translational against block 2 have good guide effect.
