Abstract
The utility model provides a turning tool for a spiral bevel gear, which can be connected to a lathe, can be used for turning an inner hole and a plane of the spiral bevel gear and is used for increasing the processing efficiency and ensuring the processing quality. The turning tool comprises a clamp seat connected with a machine tool main shaft, wherein a clamp body is fixed on the clamp seat, and is provided with a support plate; the support plate is provided with at least three positioning balls which are uniformly distributed in the circumferential direction of the spiral bevel gear; three pressure plates sleeved on three pull rods are used for compressing the spiral bevel gear on a positioning ball; the lower end of a pull rod is connected with a fork-shaped plate by passing through the clamp body; the central part of the fork-shaped plate and a movable slide block form a spherical pair; the movable slide block is provided with a central screw rod connected with a main shaft oil cylinder of the machine tool; and the pressure plates are connected with the pull rod through spiral pairs.
Description
Technical field
Present technique relates to spiral bevel gear turning frock.
Background technology
Spiral bevel gear is as shown in Figure 1, and spiral bevel gear case hardness HRC58-62, pitch circle be for the circle of endoporus 0.06 mm that beats, and big plane T is for the circle of endoporus beat 0.025mm, flatness 0.015 mm, and slightly releasing souls from purgatory requirement is Ra1.6; Its structure is special to be that endoporus φ 58.50.019 0 front portion has 1 internal spline; The internal spline path is φ 55.6, and escape φ 59 length have only 5 mm in the middle of both, process on internal grinder according to traditional method for grinding; Mill endoporus φ 58.50.019 0 earlier, goes out T face light again; Processing gets up to waste time and energy, and mainly is that escape φ 59 length have only 5 mm, the emery wheel bad control that moves back and forth, each order of classes or grades at school can only grind more than 30, efficient is not high since every batch quantity is many and delivery date is short, bring certain degree of difficulty so give to produce.
Summary of the invention
The purpose of present technique provides a kind of can being connected on the lathe, can carry out turning processing to endoporus, the plane of spiral bevel gear, to improve working (machining) efficiency and to guarantee the spiral bevel gear turning frock of crudy.
This spiral bevel gear turning frock; It comprises that is used for a clamping fixture seat that links to each other with machine tool chief axis; On clamping fixture seat, be fixed with clamp body; Support plate is set on the clamp body, and support plate is provided with at least three place kick that are distributed on the spiral bevel gear circumferential direction, and three block pressur plates that are sleeved on three pull bars are used for being pressed on place kick to spiral bevel gear; The pull bar lower end is passed clamp body and is linked to each other with the fork-shaped plate; The central part of fork-shaped plate and movable slider form spherical pair; Be provided for the center bolt that links to each other with the main shaft oil cylinder of lathe on the movable slider; Pressing plate links to each other with screw pair with pull bar.
Above-mentioned spiral bevel gear turning frock, the pull bar lower end is fixed on the fork-shaped plate through round nut.
The beneficial effect of present technique: place kick is evenly distributed on by one group (more than three) on the fixing circumference of the support plate centre of gyration, and is consistent with the centre of gyration of support plate to play each place kick.During processing parts; Be placed on part in the place kick and locate with pitch circle; So just guaranteed that pitch circle, part endoporus, support plate and machine tool chief axis have the unified centre of gyration; Pressing plate is pressed on the part, shrinks the tension center bolt through the machine tool chief axis oil cylinder and passes for going up clamping work pieces to movable control agent (pull bar 1 is fixed on formation activity control agent on the fork-shaped plate 8 through round nut 9) through the fork-shaped plate, and workpiece clamps the back and just can use ceramic tip turning to accomplish the processing of workpiece.
Because the gear mill teeth with endoporus, plane positioning processing, has been avoided the benchmark transformed error when therefore doing benchmark turning endoporus, plane with the pitch circle location, has guaranteed uniformity and the morpheme error requirements and the accuracy of gear requirement of size.Through the machined into part, can process 150-160 spare every day with these anchor clamps, and production efficiency has improved 5-6 doubly, and part quality also increases simultaneously.
Description of drawings
Fig. 1 is the sketch map of spiral bevel gear.
Fig. 2 is the sketch map of this spiral bevel gear turning frock.
The specific embodiment
Combine accompanying drawing that present technique is done further to describe through embodiment below.
As shown in Figure 2; These anchor clamps are connected with numerically controlled lathe CK7516 main shaft through screw 10 by clamping fixture seat 14; Clamp body 7, support plate 4, place kick 3 usefulness screws 11, nut 5 are coupled to one and are connected on the clamping fixture seat 14 with machine tool chief axis through screw 6 and form a fixing revolving body, have guaranteed that support plate is consistent with the machine tool chief axis centre of gyration;
Be contained on the pull bar 1 by pressing plate 2 and can rotate freely through thread connection, pull bar 1 is fixed on through round nut 9 and forms the movable control agent that can move up and down on the fork-shaped plate 8.
Place kick is by consistent with the centre of gyration of support plate to play six place kick on six the one group fixing circumference that is evenly distributed on the support plate centre of gyration; During processing parts: be placed on part in the place kick 3 and locate with pitch circle; So just guaranteed that pitch circle, part endoporus, support plate and machine tool chief axis have the unified centre of gyration; Pressing plate 2 is pressed on the part 16; Shrink tension center bolt 15 through the machine tool chief axis oil cylinder and pass for clamping work pieces 16 to movable control agent through fork-shaped plate 8, workpiece clamps the back and just can use ceramic tip turning to accomplish the processing of workpiece.
