Abstract
The utility model discloses a kind of machine chuck, it comprises pull bar, chuck main body, tip chute, pawl core, pawl head, chuck main body inside is provided with two tip chutes, is equipped with pawl core in each tip chute, and each pawl core external port is connected with pawl head, pull bar one end is positioned at chuck main body, be connected with pawl core, the other end stretches out outside chuck main body, and each pawl head top is connected with pawl head cavity, single action screw mandrel is through pawl head cavity, and fixed claw head body is connected with single action screw mandrel one end.It is simple and compact for structure and clamp precision is high, does not need frequently to change chuck at work, increases work efficiency.
Description
Technical field
The utility model relates to a kind of plant equipment, particularly relates to a kind of machine chuck.
Background technology
Chuck is generally made up of chuck main body, movable jaw and claw driving mechanism, and claw driving mechanism drives the movable jaw be distributed on chuck body to move radially, and is located by Workpiece clamping.Chuck can be divided into from the pawl number of movable jaw: two-jaw(ed)chuck, scroll chuck, chuck etc.At present, the claw driving mechanism of chuck is bevel gear wheel, and the bevel pinion that with movable jaw be connected equal with movable jaw quantity, there is flat thread at the back side of bevel gear wheel, bevel pinion engages with the flat thread of bevel gear wheel, bevel gear wheel connects motor, driven by motor bevel gear wheel rotates, and the flat thread of bevel gear wheel makes bevel pinion drive movable jaw simultaneously close to the center of chuck body or exit, and so just achieves and clamps or unclamp workpiece.But the complex structure of current this chuck, manufactures inconvenience, and clamping or the process of unclamping workpiece rapid, have impact on working (machining) efficiency.
Chuck is the effect playing clamping work pieces in lathe work, the well-regulated cylindrical of cylindrical due to workpiece and irregular cylindrical point, so, general lathe is also just correspondingly equipped with self-centering expansion chuck and single action expansion chuck, carry out the clamping to regular cylindrical and irregular outer circular Curve respectively, simultaneously, in the workpiece of some eccentric shaft classes and the processing of some other workpiece, also different chucks to be used respectively, due to these situation, so, need the requirement according to workpiece situation and technique at work, chuck is changed frequently on lathe, thus reduction production efficiency
Utility model content
Technical problem to be solved in the utility model is to provide a kind of machine chuck, and it is simple and compact for structure and clamp precision is high, does not need frequently to change chuck at work, increases work efficiency.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of machine chuck, it is characterized in that, it comprises pull bar, chuck main body, tip chute, pawl core, pawl head, chuck main body inside is provided with two tip chutes, pawl core is equipped with in each tip chute, each pawl core external port is connected with pawl head, pull bar one end is positioned at chuck main body, be connected with pawl core, the other end stretches out outside chuck main body, each pawl head top is connected with pawl head cavity, and single action screw mandrel is through pawl head cavity, and fixed claw head body is connected with single action screw mandrel one end.
Preferably, described pawl head is connected by the end of bolt with pawl core.
Preferably, described tip chute circumference on chuck main body is uniformly distributed.
Preferably, described chuck main body is tubular.
Positive progressive effect of the present utility model is: the utility model is simple and compact for structure and clamp precision is high, does not need frequently to change chuck at work, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model machine chuck.
Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model machine chuck comprises pull bar 1, chuck main body 2, tip chute 3, pawl core 4, pawl head 5, chuck main body 2 inside is provided with two tip chutes 3, is equipped with pawl core 4 in each tip chute 3, and each pawl core 4 external port is connected with pawl head 5, pull bar 1 one end is positioned at chuck main body 2, be connected with pawl core 4, it is external that the other end stretches out chuck master 2, and each pawl head 5 top is connected with pawl head cavity 7, single action screw mandrel 8 is through pawl head cavity 7, and fixed claw head body 9 is connected with single action screw mandrel 8 one end.Pawl head 5 is connected with the end of pawl core 4 by bolt 6.Tip chute 3 circumference on chuck main body 2 is uniformly distributed.Chuck main body 2 is in tubular.
Pawl head 5 in use, is connected in the end of pawl core 4 by this machine chuck by bolt 6.On pawl head 5, single action screw mandrel 8 is housed independently, so the rotation class of rule or non-rotating class workpiece can be clamped easily, does not need frequently to change chuck at work, increase work efficiency.Add man-hour, pull bar 1 pulls pawl core 4 to tighten up in chuck main body 2 axle center in tip chute 3, each pawl head 5 with pawl core 4 movement and tighten up to chuck main body 2 axle center, so just achieve the clamping of pawl head 5 pairs of workpiece, clamping intermediate link few, clamp faster.After work pieces process, the movement of pull bar 1 driving pawl core 4 to external diffusion centered by chuck main body 2 axle center in tip chute 3, pawl head 5 opens, and achieves unclasping workpiece, unclasps workpiece quick equally.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
