Abstract
The utility model discloses a chuck used for processing joint threads of a rope drilling rod comprising a housing. The housing is slidably connected with a pulling plate. One end of the pulling plate is connected with a plurality of nitrogen springs, and a middle part is connected with a pushing rod driven by a hydraulic station, and the other end of the pulling plate is connected with a sliding wedge. A wedge-shaped surface of the sliding wedge is provided with a clamping wedge cooperated with the sliding wedge, and an inner side of the clamping wedge is detachably provided with a soft claw. The chuck used for processing the joint threads of the rope drilling rod adopts the nitrogen springs as the power, and therefore the enough clamping force can be guaranteed; by adopting the soft claw for the clamping, the clamping is stable, the precision is high, and the workpiece is not easy to scratch. In addition, the clamping surface of the soft claw adopts the arc-shaped surface, and therefore the coaxiality of the workpiece clamping can be effectively guaranteed, the structure is simple, the clamping is easy to realize, the labor intensity of workers can be reduced, and the working efficiency can be improved.
Description
Technical field
The utility model relates to a kind of chuck, relates 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 by manual operation, to be clamped the joint of cord drill-rod, yet, the joint screw thread processing request axiality of cord drill-rod is higher, because workpiece is thinner, manually clamp deviation larger, easily there is the inclined to one side phenomenon of folder; 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.
Utility model content
The purpose of this utility model is for the problems referred to above, a kind of joint screw thread processing chuck of cord drill-rod is provided, to solve the joint screw thread processing of original cord drill-rod, adopt scroll chuck manual operation 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 purpose of this utility model is to be achieved through the following technical solutions:
A kind of joint screw thread processing chuck of cord drill-rod, comprise housing, on described housing, slidably connect arm-tie, one end of described arm-tie is connected with a plurality of nitrogen springs, its middle is connected with the push rod being driven by Hydraulic Station, the other end of arm-tie is connected with sliding wedge, is provided with the clamping voussoir matching with it on the lozenges of described sliding wedge, the interior dismountable soft pawl that is provided 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.
The beneficial effects of the utility model are 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of chuck for the joint screw thread processing of the utility model cord drill-rod.
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
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of chuck for the joint screw thread processing of the utility model cord drill-rod, in the present embodiment, a kind of joint screw thread processing chuck of cord drill-rod, comprise housing 1, on described housing 1, slidably connect arm-tie 6, one end of described arm-tie 6 is connected with 8 nitrogen springs 8, its middle is connected with the push rod 7 being driven by Hydraulic Station 9, the other end of arm-tie 6 is connected with sliding wedge 2, on the lozenges of described sliding wedge 2, be provided with the clamping voussoir 3 matching with it, described clamping voussoir 3 is six valve structures, between the gap between adjacent two lobes, be provided with caulking gum, the interior dismountable soft pawl 4 that is provided 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 being fixedly connected with it to move to right, and sliding wedge 2 moves to right to clamping 3 one downward power of voussoir, clamps voussoir 3 and drives the soft pawl 4 on it to move down clamping work pieces 5; After machining, Hydraulic Station 9 drives push rod 7 to be moved to the left, and push rod 7 drives arm-tie 6 to be moved to the left, and arm-tie 6 drives the sliding wedge 2 being fixedly connected with it to be 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 utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
