Circular tensile sample is large in metallurgy industry scientific research and testing use amount, and traditional processing technology is to adopt engine lathe first blank to be carried out to roughing, re-uses cylindrical grinder or numerically controlled lathe fine finishining, and manufacturing procedure is many, and labour intensity is large, and production efficiency is low.
Summary of the invention
The purpose of this utility model will overcome above-mentioned deficiency exactly, and a kind of rectangular billet clamp for machining of simple in structure, clamping is convenient, production efficiency is high circular tensile sample is provided.
For achieving the above object, the rectangular billet clamp for machining of the designed circular tensile sample of the utility model, comprise the top and tailstock rolling center of head movement for holding out against rectangle sample blanks two ends, in the top scroll chuck that is arranged on numerically controlled lathe of described head movement, described tailstock rolling center is arranged on the tailstock of numerically controlled lathe, its special character is: also comprise fixing pincers, in the middle of described fixing pincers, offer the sealing jaw passing through for rectangle sample blanks, described sealing jaw top is provided with bolt hole, in described bolt hole, be provided with the fastening bolt with its threaded engagement, described fastening bolt coordinates with the rectangle sample blanks butt in sealing jaw in the time of clamp position, described sealing jaw bottom is provided with mechanical arm, and described mechanical arm is bending structure, and its one end is fixedly connected with sealing jaw bottom, and its other end is in the time of clamp position and extend between the claw of scroll chuck.
Preferably, the cross section of described mechanical arm is rounded, and mechanical arm is 90 ° of bending structures.
In order to adapt to the excursion of rectangle sample training sectional dimension, preferably, the top of described sealing jaw is planar shaped, and the bottom of described sealing jaw takes the shape of the letter U.
The invention has the advantages that: when described fixing pincers clamp rectangle sample blanks, make rectangle end face vertical with the axis direction of lathe thimble, accurately realize centralized positioning, and can in lathe spindle High Rotation Speed situation, transmit cutting moment; Can adapt to the excursion of rectangle sample blanks sectional dimension, fast clamp; Numerically controlled lathe is clamped and can be completed circular tensile sample processing by a blank, avoids multiple operation, repeatedly clamps, and reduces labour intensity, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of rectangular billet clamp for machining structural representation of circular tensile sample.
Fig. 2 is the blast structural representation of Fig. 1.
Fig. 3 fixes wrench structure schematic diagram in Fig. 1.
In figure: rectangle sample blanks 1, head movement is top 2, tailstock rolling center 3, scroll chuck 4, fixing pincers 5, sealing jaw 6, mechanical arm 7, claw 8, fastening bolt 9, bolt hole 10, stop dog position 11, CNC turning tool 12, circular tensile sample 13, off-position 14.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The rectangular billet clamp for machining of the circular tensile sample shown in figure, comprise head movement top 2 and tailstock rolling center 3 for holding out against rectangle sample blanks 1 two ends, head movement top 2 is arranged in the scroll chuck 4 of numerically controlled lathe, described tailstock rolling center 3 is arranged on the tailstock of numerically controlled lathe, it is characterized in that: also comprise fixing pincers 5, in the middle of described fixing pincers 5, offer the sealing jaw 6 passing through for rectangle sample blanks 1, described sealing jaw 6 tops are provided with bolt hole 10, in described bolt hole 10, be provided with the fastening bolt 9 with its threaded engagement, described fastening bolt 9 coordinates with rectangle sample blanks 1 butt in sealing jaw 6 in the time of clamp position, described sealing jaw 6 bottoms are provided with mechanical arm 7, described mechanical arm 7 is bending structure, its one end is fixedly connected with sealing jaw 6 bottoms, and its other end is in the time of clamp position and extend between the claw 8 of scroll chuck 4, and mechanical arm cross section is rounded and be 90 ° of bending structures.Sealing jaw 6 tops are planar shaped, and the bottom of sealing jaw 6 takes the shape of the letter U, and such design is the change in size scope in order to meet rectangular billet.
Before 1 processing of rectangle sample blanks, use diameter 4mm centre drill at two centre bores of the each brill of rectangular billet 1 two ends entad.While clamping, rectangle sample blanks 1 is in position through the sealing jaw 6 of fixing pincers 5, fastening bolt 9 is pressed in rectangle sample blanks 1 upper surface by the bolt hole 10 on fixing pincers 5, two limits of rectangle sample blanks 1 lower surface can contact with sealing jaw 6 under fastening bolt 9 pretightning force effects simultaneously, rectangle sample blanks 1 can be fixed in sealing jaw 6 like this, then by rectangle sample blanks 1 two ends centre bore respectively, tailstock rolling center 3 top 2 with head movement coordinate, and clamp tailstock rolling center 3, realize rectangular specimen 1 centering location.Now, the mechanical arm 7 of fixing pincers 5 is vertically inserted in certain distance between any two claws 8 of scroll chuck 4.
When numerically controlled lathe work, as shown in Figure 1, spindle of numerical control lathe drives scroll chuck 4 to be rotated in the forward, and mechanical arm 7 contacts with a claw 8 of scroll chuck 4, and this contact point is mechanical arm 7 stop dog positions 11.At stop dog position 11, main shaft passes torque to mechanical arm 7 and drives whole fixing pincers 5 to rotate with main shaft, because rectangle sample blanks 1 is fixed in fixing pincers 5, the cutting moment that this moment can produce with CNC turning tool 12 balances each other, drive rectangle sample blanks 1 synchronous main shaft to be rotated in the forward motion, realize the processing to rectangle sample blanks 1.After circular tensile sample 13 main bodys machine, the off-position 14 that can use numerically controlled lathe cutoff tool that rectangle sample blanks is cut between circular tensile sample 13 is switched to diameter 2mm tie point, and stop main shaft rotate, return tailstock rolling center 3, the tie point at the rectangle sample blanks that manually fractures 1 and circular tensile sample 13 off-position places, takes out circular tensile sample 13; Meanwhile, unclamp tight fixed bolt 9, take out remaining blank.
