Abstract
Disclosed is a welded pipeline lathing beveled edge auxiliary clamping device. The welded pipeline lathing beveled edge auxiliary clamping device comprises a front three jaw chuck (1) and a rear three jaw chuck (2), wherein the front three jaw chuck (1) and the rear three jaw chuck (2) are in the same structure. The welded pipeline lathing beveled edge auxiliary clamping device is characterized in that supporting arms are installed on the front three jaw chuck (1) and the rear three jaw chuck (2). The supporting arms can telescope with a jack catch synchronously, and are used for abutting against the inner wall of a pipeline. The front three jaw chuck (1) is installed on a main shaft of a lathe in a clamping mode. The rear three jaw chuck (2) is connected with a shaft sleeve (4). The shaft sleeve (4) is installed on a tailstock taper sleeve (5) of the lathe in a rotatable mode. A to-be-processed pipeline only needs to be clamped once, and beveled edges at the two ends of the pipeline can be lathed. Parallelism of end faces of two pipe ports can be controlled within 0.1 millimeter so that problem of the pipeline that part group clearance is big caused by unparallel end faces in a pipeline prefabricating process is solved.
Description
Technical field
The utility model relates to a kind of machinery processing apparatus, especially a kind of large-scale pipeline groove fixture for processing, specifically a kind of welded pipe line Vehicle Processing groove auxiliary clamping device.
Background technology
At present, in actual production process, for the heavy caliber welded tube that rolls, in order to guarantee welding quality, the mouth of pipe need to be processed into groove, and existing finished edge generally has following dual mode:
1. manual grinding, the irregular and mouth of pipe both ends of the surface depth of parallelism of groove can not be guaranteed.
2. machining, lathe or beveling machine processing, groove is regular but need carry out secondary clamping, and for the long and relatively heavier pipeline of length, the process of clamping relatively takes time and effort, and the mouth of pipe both ends of the surface depth of parallelism can not be guaranteed.
Therefore, designing a kind of novel clamping device is the key that solves a Large Diameter Long Pipes groove processing difficult problem.
Summary of the invention
The purpose of this utility model is the problem that can not adapt to Large Diameter Long Pipes groove processing for existing clamping device, designs a kind of not only convenient mounting and clamping but also can guarantee the welded pipe line Vehicle Processing groove auxiliary clamping device of crudy.
The technical solution of the utility model is:
A kind of welded pipe line Vehicle Processing groove auxiliary clamping device, it comprises front scroll chuck 1 and the rear scroll chuck 2 that structure is identical, it is characterized in that described front scroll chuck 1 and rear scroll chuck 2 all be equipped with can with the claw synchronization telescope, be used for the support arm 3 that offsets with inner-walls of duct, described front scroll chuck 1 clamping is on lathe spindle, described rear scroll chuck 2 links to each other with axle sleeve 4, and axle sleeve 4 is installed in rotation on the lathe tailstock tapered sleeve 5.
Be connected with the arc back-up block 6 that radian and pipeline 8 inwall radians match on the described support arm 3.
Described lathe tailstock tapered sleeve 5 is equipped with bearing 7, and axle sleeve 4 is sleeved on the bearing 7.
The beneficial effects of the utility model:
The utility model can make pipeline to be processed only need clamped one time, but just Vehicle Processing pipe ends groove, and two mouth of pipe faces parallels can be controlled in the 0.1mm, so as to solve this pipeline when pipeline precast since the not parallel group that causes of end face to the local problems of too in gap.
The utility model is simple in structure, and is easily manufactured.
Description of drawings
Fig. 1 is use status architecture schematic diagram of the present utility model.
Fig. 2 be after the utility model improves scroll chuck face structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1-2.
A kind of welded pipe line Vehicle Processing groove auxiliary clamping device, it comprises front scroll chuck 1 and the rear scroll chuck 2 that structure is identical, described front scroll chuck 1 and rear scroll chuck 2 all be equipped with can with the claw synchronization telescope, be used for the support arm 3 that offsets with inner-walls of duct, be connected with the arc back-up block 6 that radian and pipeline 8 inwall radians match on the support arm 3, such as Fig. 2, described front scroll chuck 1 clamping is on lathe spindle, described rear scroll chuck 2 links to each other with axle sleeve 4, axle sleeve 4 is sleeved on bearing 7, and bearing 7 is installed on the lathe tailstock tapered sleeve 5.As shown in Figure 1.
As shown in Figure 1, with the clamping of scroll chuck after improving on the original chuck of lathe, scroll chuck after the other improvement is equipped with the device clamping of bearing to tailstock by inside, pipeline clamping to be processed is between two chucks, push against inner-walls of duct with the support arm 3 claw synchronization telescope, that be used for offseting with inner-walls of duct, pipe ends mouth of pipe outer wall guarantees that without gripping object lathe tool can be with the groove machine-shaping of mouth of pipe two ends on the stroke track like this.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
