Abstract
The utility model relates to the tensile sample machining, in particular to the small round head tensile sample machining. The utility model discloses a clamp used for the small round head tensile sample machining, which comprises a pair of collets; wherein each collet comprises a stretching section and a clamping section which are integrated as a whole; the excircle cambered surface of the clamping section is provided with a U-shaped groove along the axial direction of the clamping section; the circle center of the circular arc at the bottom of the groove coincides with that of the cross section of the clamping section; and the U-shaped groove is provided with a step with gradually largening diameter, so that the U-shaped groove is divided into a large diameter section and a small diameter section. The utility model can improve the machining efficiency of the small round head tensile sample, reduce the material consumption cost, and decrease unnecessary labor cost and equipment operation.
Description
Technical field
The utility model relates to the processing of tensile sample, relates in particular to the processing of roundlet head tensile sample.
Background technology
Original processing because of being subjected to the restriction of puller system to specimen length, must be passed through sample welding welding rod spreading specimen length than short round tensile sample flow process after sawing becomes sample, can carry out machined into again, and because of operation is many, working (machining) efficiency is lower on work flow.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above, and a kind of roundlet head tensile sample fixture for processing is provided.The utility model can improve the working (machining) efficiency of roundlet tensile sample, reduces the goods, materials and equipments consuming cost, reduces unnecessary cost of labor and equipment operation.
The utility model is achieved in that a kind of roundlet head tensile sample fixture for processing, it comprises a pair of chuck, each chuck is stretch section and the gripping section that connects as one, the exterior arc surface upper edge gripping section of described gripping section is axially arranged with one U-lag, the center of circle of its bottom land circular arc and the center of circle, gripping section cross section overlap, thereby have a big step of diameter change in this U type groove this U-lag are divided into enlarged diameter section and reduced diameter section.
Described roundlet head tensile sample fixture for processing, the step top of described U-lag has chamfering.
Described roundlet head tensile sample fixture for processing, the rounded nose diameter of the diameter of the enlarged diameter section of described U-lag and tensile sample to be processed adapts.
The utility model is simplified the work flow of roundlet head tensile sample, only needs sawing machine cutting and lathe turning.Thereby the minimizing manufacturing procedure reduces the goods, materials and equipments consumption of welding pole, guarantees the machining precision of roundlet tensile sample.
Description of drawings
Below, the utility model is described in further detail in conjunction with the accompanying drawings:
Fig. 1 is a front elevation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2: plant roundlet head tensile sample fixture for processing, it comprises a pair of chuck 1, each chuck is stretch section 11 and the gripping section 12 that connects as one, the exterior arc surface upper edge gripping section 11 of described gripping section 12 is axially arranged with one U-lag 2, the center of circle of its bottom land circular arc and the center of circle, gripping section 11 cross section overlap, thereby have a big step 21 of diameter change in this U type groove 2 this U-lag are divided into enlarged diameter section 22 and reduced diameter section 23.
Described roundlet head tensile sample fixture for processing, step 21 tops of described U-lag 2 have chamfering (failing among the figure to express).
Described roundlet head tensile sample fixture for processing, the rounded nose diameter of the diameter of the enlarged diameter section 22 of described U-lag and tensile sample to be processed adapts to hold sample.
Claims (3)
