Abstract
The utility model discloses a balance shaft turning fixture which comprises a chuck jaw (1), chuck jaws (2), a positioning block (3) and a cylindrical pin (4); the chuck jaws (2) form an angle of 120 DEG and are tightly clamped on the semicircle of a balance shaft; and the cylindrical pin (4) and the positioning block (3) are mounted at the head parts of the chuck jaws (2). The balance shaft turning fixture of the utility model has the advantages that when the jaws are mounted, the radial positions of the three chuck jaws are adjusted through chuck cogs so as to ensure that the intersection point of two inclined surfaces of the balance shaft is coincident with the gyration centre of a machine tool during contraction, so that the dimensional precision of the turned balance shaft can reach the drawing requirements; and the two inclined surfaces are taken as the standard to ensure turning standard coincidence.
Description
Technical field
The utility model relates to a kind of trunnion shaft vehicle clamper.
Background technology
The trunnion shaft of car balancer has eccentric structure (seeing Fig. 1 and Fig. 2), blank after the casting is carried out rough turn processing earlier, rough turn adding, wanted first clamping semi-circular structure man-hour, car right side, cylindrical centering, car left side, cylindrical, centering again, the axiality in the two ends centre bore and the semicircle center of circle is the basis of postorder machining accuracy, and conventional numerically controlled lathe scroll chuck can't carry out the requirement that clamping satisfies rough turn clamping and positioning to eccentric position, therefore, need design one cover special fixture to come the clamping blank to carry out rough turn processing.
The utility model content
The purpose of this utility model provides a kind of by serving as the location benchmark with two inclined-planes, guarantees the trunnion shaft vehicle clamper of turning datum coincidence.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of trunnion shaft vehicle clamper, comprise chuck jaw (1), chuck jaw (2,2), locating piece (3) and straight pin (4), described chuck jaw (2,2) is on the semicircle that hexagonal angle is clamped in trunnion shaft, and straight pin (4) and locating piece (3) are installed in the head of chuck jaw (2,2).
Described chuck jaw (1) and chuck jaw (2,2) are fixed on the machine chuck body (5) by fastening bolt (6).
The rotatable locating piece that described locating piece (3) is made for straight pin (4).
Described chuck jaw (1) and chuck jaw (2,2) are 4 contact chuck pawls.
Described locating piece (3) is 2 contact locating pieces.
The utility model trunnion shaft vehicle clamper, when installing, claw adjusts the radial position of three chuck jaws by the chuck teeth, trunnion shaft two inclined-plane intersection points just in time overlap with the machine tool rotary center when guaranteeing to shrink, trunnion shaft dimensional accuracy after the turning just can reach the drawing requirement like this, with two inclined-planes is the location benchmark, guarantees the turning datum coincidence.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the trunnion shaft structure chart of prior art;
Fig. 2 is that Figure 1A-A is to cutaway view;
Fig. 3 is a kind of trunnion shaft vehicle clamper of the utility model structure chart;
Fig. 4 is that Fig. 3 B-B is to cutaway view.
Among the figure: 1, chuck jaw; 2, chuck jaw; 3, locating piece; 4, straight pin; 5, machine chuck body; 6, fastening bolt.
The specific embodiment
As shown in Figure 3 and Figure 4, the utility model trunnion shaft vehicle clamper, comprise chuck jaw 1, chuck jaw 2, locating piece 3 and straight pin 4, be between two chuck jaws 2 on the semicircle that hexagonal angle is clamped in trunnion shaft, straight pin 4 and locating piece 3 are installed in the head of chuck jaw 2, chuck jaw 1 and chuck jaw 2 are fixed on the machine chuck body 5 by fastening bolt 6, the rotatable locating piece that locating piece 3 is made for straight pin 4, chuck jaw 1 and chuck jaw 2 are 4 contact chuck pawls, locating piece 3 is 2 contact locating pieces, the frame mode of the utility model trunnion shaft vehicle clamper design principle for adopting chuck jaw to clamp, special jaw is located by teeth, bolt is clamped on numerically controlled lathe (CL-20A) oild chuck, realize that by hydraulic system workpiece clamps, at first, designing location, 1 pair of inclined-plane of a chuck jaw clamps, to calculate the weight of semicircle during design, the weight that calculates is added on the designed chuck jaw 1, to remedy the eccentric weight of semicircle, lathe can not vibrate during turning like this, to consider the influence of the roughness of casting surface and form accuracy simultaneously to clamping, chuck jaw is designed to the pattern of 4 contacts, to improve positioning accuracy; Secondly, two the same 2 pairs of semicircles of chuck jaw of pattern of design are 120 degree and carry out clamping and positioning on the semicircle of trunnion shaft, chuck jaw 2 heads are made rotatable locating piece by straight pin 4, locating piece 3 is designed to the form of 2 contacts, the problem that the two ends of chuck jaw can not all contact in the time of can not clamping because of the defective effect of casting surface like this realizes accurately location; At last, adjust the radial position of three chuck jaws when claw is installed by the chuck teeth, trunnion shaft two inclined-plane intersection points just in time overlap with the machine tool rotary center when guaranteeing to shrink, and the trunnion shaft dimensional accuracy after the turning just can reach the drawing requirement like this.
The utility model trunnion shaft vehicle clamper operation principle is: at first, clean numerically controlled lathe chuck body end face, guarantee that teeth, locating slot place do not have iron filings, foreign material; Secondly, chuck jaw 1, chuck jaw 2 are installed in respectively on the machine chuck body 5, guarantee that last teeth is 113mm to the chuck centre of gyration, with fastening bolt 6 fixing tight chuck jaws; At last, the operator finishes numerical control program, workpiece is put between the chuck jaw, stir lathe switch clamping work pieces, carry out a rough turn end cylindrical, end face and centering, then workpiece is unloaded, carry out the processing of cylindrical, end face, centre bore to another numerical control car, rough turn back examining workpieces dimensional accuracy, produce in batches qualified back.
