Detailed Description
The invention is further described below with reference to the drawings and the detailed description.
In order to provide a fixture specifically for spherical turning in a differential housing, as shown in fig. 1-3: the spherical turning fixture in the differential case comprises a differential case fixing frame 1, a middle supporting plate 2, a positioning pin 3, a positioning pin mounting strip 4, a clamping shaft 6 and a compacting structure 5; the differential case fixing frame 1 includes a rectangular first end plate 11, a rectangular second end plate 12, and four connecting bars; the first end plate 11 and the second end plate 12 are opposite to each other and are arranged at intervals, two ends of the four connecting strips are respectively connected with four corners of the first end plate 11 and the second end plate 12, a first U-shaped groove 111 facing the top of the differential case fixing frame 1 is arranged on the first end plate 11, a semicircular bearing mounting excircle fixing groove 112 is arranged on the groove bottom of the first U-shaped groove 111, the connecting strip positioned at the top of the differential case fixing frame 1 is a top connecting strip 13, and the connecting strip positioned at the bottom of the differential case fixing frame 1 is a bottom connecting strip 14; the middle supporting plate 2 is positioned between the first end plate 11 and the second end plate 12 and is connected with the bottom connecting strip 14, and a semicircular positioning excircle fixing groove 21 is formed in the middle supporting plate 2; the positioning pin 3 and the positioning pin installation strip 4 are positioned between the first end plate 11 and the middle support plate 2, the positioning pin installation strip 4 is connected with the bottom connecting strip 14, and the positioning pin 3 is arranged above the positioning pin installation strip 4 and is connected with the positioning pin installation strip 4; the clamping shaft 6 is positioned outside the differential case fixing frame 1, and the clamping shaft 6 is vertical to and connected with the second end plate 12; the clamping shaft 6, the bearing installation outer circle fixing groove 112 and the positioning outer circle fixing groove 21 are coaxially arranged, and the bearing installation outer circle fixing groove 112 and the positioning outer circle fixing groove 21 face the top of the differential housing fixing frame 1; the compression structure 5 is connected with the top connecting strip 13; when the differential housing 7 is clamped, the bearing mounting excircle 71 at one end of the differential housing 7 is placed in the bearing mounting excircle fixing groove 112, the positioning excircle 72 of the differential housing 7 is placed in the positioning excircle fixing groove 21, the positioning pin 3 is inserted into the planetary gear shaft hole 73 of the differential housing 7, and the pressing structure 5 presses the differential housing 7.
The process and principle of the invention for clamping the differential housing 7 are as follows: A. the differential case 7 is put into the differential case fixing frame 1, the bearing mounting outer circle 71 is put into the bearing mounting outer circle fixing groove 112, the positioning outer circle 72 is put into the positioning outer circle fixing groove 21, and the planetary gear shaft hole 73 is sleeved on the positioning pin 3. The positioning pin mounting bar 4 may not be installed first, and the positioning pin mounting bar 4 may be installed after the differential case 7 is put in, so that the positioning pin 3 may be inserted into the planetary gear shaft hole 73. B. The differential case 7 is pressed against the bearing mounting outer circumference fixing groove 112 and the positioning outer circumference fixing groove 21 by the pressing structure 5. The bearing-mounting outer-circle fixing groove 112, the positioning outer-circle fixing groove 21, the positioning pin 3, and the pressing structure 5 together restrict the movement of the differential case 7, and the positioning pin 3 also restricts the rotation of the differential case 7.
After the differential case 7 is fixed, the clamp is fixed to the lathe spindle, and the turning tool is allowed to enter the differential case 7 before the clamp is fixed to the lathe spindle. The clamp may be secured to the machine spindle by clamping the clamping shaft 6 with a three-jaw chuck such that the clamping shaft 6 is concentric with the machine spindle. The clamping shaft 6, the bearing mounting outer circle fixing groove 112 and the positioning outer circle fixing groove 21 are coaxially arranged, and the spherical center of the inner spherical surface 74 is positioned at the intersection point of the axis of the bearing mounting outer circle 71 and the axis of the planetary gear shaft hole 73, so that the spherical center of the inner spherical surface 74 is positioned on the main shaft of the machine tool, and tool setting of a turning tool is facilitated.
The specific arrangement modes of the pressing structure 5 can be various, and the recommended modes of the invention are as follows: the compression structure 5 comprises a compression bar 52, a compression bar supporting rod 51, a push rod 53, a rotary rod 55, a rotary rod seat 56 and a compression nut 54; the layering strut 51 is connected with one top connecting strip 13, the rotating rod seat 56 is connected with the other top connecting strip 13, and the rotating rod 55 is hinged with the rotating rod seat 56; one end of the pressing bar 52 is hinged with the pressing bar supporting rod 51, and a second U-shaped groove 521 is arranged at the other end of the pressing bar 52; the compression nut 54 is in threaded connection with the rotating rod 55, and when the rotating rod 55 rotates and enters the second U-shaped groove 521, the compression nut 54 can press down the pressing bar 52; the ejector rod 53 faces the bottom of the differential case fixing frame 1 and is connected to the middle of the bead 52.
The process of pressing the differential case 7 by the pressing structure 5 is as follows: A. the bead 52 is rotated to cause the carrier rod 53 connected thereto to ride on the differential case 7. B. The rotating lever 55 is rotated into the second U-shaped groove 521. C. The pressing nut 54 is rotated to press the pressing bar 52, so that the jack 53 is pressed down against the differential case 7. When the differential case 7 is removed, the differential case 7 can be removed by slightly loosening the compression nut 54 and rotating the rotating lever 55 away from the second U-shaped groove 521, i.e., rotating the bead 52 away from the upper side of the differential case 7. It can be seen that the compressing structure 5 has the advantage of simple and convenient fixing and releasing operation.
The clamping shaft 6 is preferably connected to the center of the second end plate 12, and the bearing mounting outer circle fixing groove 112 and the positioning outer circle fixing groove 21 are correspondingly positioned at the center of the differential case fixing frame 1, and the differential case 7 is also positioned at the center of the differential case fixing frame 1 after being installed, so that the center of gravity of the clamping apparatus clamping the differential case 7 is basically positioned on the main shaft of the machine tool, thereby being beneficial to reducing the centrifugal force during rotation.
