Abstract
The utility model discloses a special holding chuck for processing a pumping rod, which comprises a wedge catch system (4) and a sliding seat (5) which are mounted on the chuck body (3) and mutually matched through transmission of an inclined plane; two transmission sides are positioned between the wedge catch system (4) and the sliding seat (5), wherein, one transmission side adopts a rapid moving inclined plane (7); and the other transmission side adopts a clamping inclined plane (8). In the structural form of double inclined planes, the rapid moving inclined plane realizes rapid movement of claws and ensures smooth material feeding and discharging operations of workpieces; and the clamping inclined plane realizes accurate positioning of workpieces and ensures the reliable clamping operation.
Description
(1), technical field
The utility model relates to a kind of chuck assembly as the numerically controlled lathe key feature.This chuck special is mainly used in the processing of petroleum industry sucker rod.
(2), background technology
At present, the sucker rod machining tool is mainly used two class chuck clamping workpieces (sucker rod), and a class is to adopt the hand chuck of flat thread type of belt drive, and its major defect is that the clamping precision is difficult to guarantee and inefficiency.Another kind of is the wedge type power chuck that adopts monocline face type of belt drive, owing to the claw stroke limiting, is difficult to satisfy the processing request of workpiece when such chuck is used for the sucker rod machining tool.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of chuck special that is used for sucker rod processing is provided, and by improving version, can increase the claw stroke, can satisfy the positioning accuracy of workpiece again.
The technical scheme that the utility model adopted is as follows:
A kind of chuck special that is used for sucker rod processing, comprise being installed on the disk body that wedge-catch system and slide by the inclined-plane transmission is worked in coordination is characterized in that: the driving face between wedge-catch system and the slide is two; First rapid traverse inclined-plane, another is to clamp the inclined-plane.
The center line angle of rapid traverse inclined-plane and disk body is between 40 °～45 °.
The center line angle that clamps inclined-plane and disk body is between 10 °～15 °.
Good effect of the present utility model is: adopt double inclined plane version, the rapid traverse inclined-plane is used to realize the claw fast moving, guarantees that the workpiece loading and unloading are smooth and easy; Clamp the accurate location that the inclined-plane is used for workpiece, guarantee reliable clamping.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.
(5), the specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this example comprises wedge-catch system with two transmissions inclined-plane 4 that is installed on the disk body 3 and the slide 5 with two transmissions inclined-plane.Described pair of transmission inclined-plane is rapid traverse inclined-plane 7 and clamps inclined-plane 8.Wherein, the center line of rapid traverse inclined-plane 7 and disk body 3 (being axis) angle is between 40 °～45 °; The center line angle that clamps inclined-plane 8 and disk body 3 is between 10 °～15 °.
Wedge-catch system 4 connects angling cylinder 1 by pull bar 2, and wedge-catch system 4 cooperates by the inclined-plane transmission with slide 5, and slide 5 connects claw 6.
Angling cylinder 1 is by pull bar 2 pulling wedge-catch systems 4, and wedge-catch system 4 drives slide 5 work by double inclined plane, thereby realizes the radially rapid traverse of claw 6 and clamp action.
Claims (3)
1, a kind of chuck special that is used for sucker rod processing comprises being installed on the disk body (3) that wedge-catch system (4) and slide (5) by the inclined-plane transmission is worked in coordination is characterized in that: the driving face between wedge-catch system (4) and the slide (5) is two; First rapid traverse inclined-plane (7), another is to clamp inclined-plane (8).
2, the chuck special that is used for sucker rod processing as claimed in claim 1, it is characterized in that: the center line angle of rapid traverse inclined-plane (7) and disk body (3) is between 40 °～45 °.
3, the chuck special that is used for sucker rod processing as claimed in claim 1 or 2, it is characterized in that: the center line angle that clamps inclined-plane (8) and disk body (3) is between 10 °～15 °.
