Abstract
The invention discloses a chuck for thread machining a connector of a rope drill pipe. The chuck comprises a shell, wherein a pulling plate is slidably connected onto the shell; a plurality of nitrogen springs are connected to one end of the pulling plate; a middle part of the pulling plate is connected with a push rod driven by a hydraulic pressure station; the other end of the pulling plate is connected with a sliding wedge block; a clamping wedge block matched with the sliding wedge block is arranged on a wedge-shaped face of the sliding wedge block; a flexible claw is detachably arranged in the clamping wedge block. The chuck for thread machining the connector of the rope drill pipe adopts the nitrogen springs as power, so that sufficient clamping force is ensured; the flexible claw is adopted for clamping, stability and high accuracy are realized, and a workpiece is not easy to scratch; in addition, a clamping face of the flexible claw adopts an arc surface, so that the coaxiality of workpiece clamping is effectively ensured, the structure is simple, the implementation is easy, the labor intensity of workers is reduced, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of chuck, relate in particular to a kind of joint screw thread processing chuck of cord drill-rod.
Background technology
At present, the processing of cord drill-rod joint completes on numerically controlled lathe, normally adopt scroll chuck to be clamped the joint of cord drill-rod by manually-operated, yet, the joint screw thread processing request axiality of cord drill-rod is higher, because workpiece is thinner, manually clamp deviation larger, the inclined to one side phenomenon of folder easily appears; In addition, because artificial clamping usually there will be not clamping situation, not only cause product rejection, also there will be security incident, greatly affected production efficiency and security.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of joint screw thread processing chuck of cord drill-rod is provided, with the joint screw thread processing that solves original cord drill-rod, adopt the scroll chuck manually-operated to carry out clamping work pieces, easily press from both sides inclined to one side, the not clamping product rejection that causes, be prone to the problem of security incident.
The objective of the invention is to be achieved through the following technical solutions:
A kind of joint screw thread processing chuck of cord drill-rod, comprise housing, slidably connect arm-tie on described housing, one end of described arm-tie is connected with a plurality of nitrogen springs, in the middle of it, place is connected with the push rod driven by Hydraulic Station, the other end of arm-tie is connected with sliding wedge, is provided with the clamping voussoir matched with it on the lozenges of described sliding wedge, the interior dismountable soft pawl that is equipped with of described clamping voussoir.
Further, the clamping face of described soft pawl is arc surface.
Further, described clamping voussoir is six valve structures, between the gap between adjacent two lobes, is provided with caulking gum.
Further, described nitrogen spring is 8.
Beneficial effect of the present invention is that the joint screw thread processing of described cord drill-rod adopts nitrogen spring as power with chuck, has guaranteed enough clamping forces, and adopt soft pawl to clamp, not only stable, precision is high, and be difficult for scratching workpiece, in addition, the clamping area of soft pawl adopts arc surface, effectively guarantees the axiality of Workpiece clamping, simple in structure, be easy to realize, reduced workman's labour intensity, improved operating efficiency.
The accompanying drawing explanation
The structural representation of chuck for the joint screw thread processing that Fig. 1 is cord drill-rod of the present invention.
In figure:
1, housing; 2, sliding wedge; 3, clamp voussoir; 4, soft pawl; 5, workpiece; 6, arm-tie; 7, push rod; 8, nitrogen spring; 9, Hydraulic Station.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to shown in Fig. 1 the structural representation of chuck for the joint screw thread processing that Fig. 1 is cord drill-rod of the present invention, in the present embodiment, a kind of joint screw thread processing chuck of cord drill-rod, comprise housing 1, slidably connect arm-tie 6 on described housing 1, one end of described arm-tie 6 is connected with 8 nitrogen springs 8, in the middle of it, place is connected with the push rod 7 driven by Hydraulic Station 9, the other end of arm-tie 6 is connected with sliding wedge 2, be provided with the clamping voussoir 3 matched with it on the lozenges of described sliding wedge 2, described clamping voussoir 3 is six valve structures, be provided with caulking gum between the gap between adjacent two lobes, the interior dismountable soft pawl 4 that is equipped with of described clamping voussoir 3, the clamping face of described soft pawl 4 is arc surface.
Add man-hour, by nitrogen spring 8, pull arm-tie 6 to move to right, arm-tie 6 drives the sliding wedge 2 be fixedly connected with it and moves to right, and sliding wedge 2 moves to right to clamping 3 one downward power of voussoir, and the soft pawl 4 that clamping voussoir 3 drives on it moves down clamping work pieces 5; After machining, Hydraulic Station 9 drives push rod 7 and is moved to the left, and push rod 7 drives arm-tie 6 and is moved to the left, and arm-tie 6 drives the sliding wedge 2 be fixedly connected with it and is moved to the left, and clamps voussoir 3 and resets, thereby unclamp workpiece 5.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
