Embodiment Construction
[0031] Preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawings;
[0032] see Figure 3 to Figure 5 , the fixture of the present invention for broaching the inner helical spline of workpiece on a common horizontal broaching machine, comprising a left coupling sleeve 20, a left bearing 23, a right bearing 24, a pull rod 30, a screw sleeve 40, a clamping member 50, and a right coupling sleeve 60 , Positioning plate 90 and pressing plate 10. Depend on Figure 3 to Figure 5It can be seen that the left bearing 23 and the right bearing 24 are set on the inside of the left end of the pull rod 30, the left end of the left coupling sleeve 20 is detachably connected to the main shaft 100 of the broaching machine, and the middle part is set on the left bearing 23 and the right bearing 24. It is set on the pull rod 30 and the diameter of the middle part is larger than the diameter of the right end, and the diameter of the rig...

The invention provides a fixture for broaching an interior spiral spline on a workpiece on a common horizontal broaching machine with high production efficiency. A left bearing and a right bearing are arranged on the inner side of the left end of a broaching rod in a sleeving mode, the left end of a left connection sleeve is connected with a broaching machine main shaft, the middle of the left connection sleeve is arranged on the left bearing and the right bearing in a sleeving mode, the right end of the left connection sleeve is arranged on the broaching rod in a sleeving mode, the aperture of the middle of the left connection sleeve is larger than that of the right end of the left connection sleeve, the aperture of the right end of the left connection sleeve is slightly larger than the outer diameter of the corresponding part of the broaching rod, a body of a thread sleeve is provided with an interior spiral spline matched with an external spiral spline on the periphery of the broaching rod, a connection part of a broaching and clamping piece is arranged on the thread sleeve body and the broaching rod in a sleeving mode, the left end of the connection part of the broaching and clamping piece is connected with a connection part of the thread sleeve, the two ends of each of two press plates are connected with a corresponding connection lug and a broaching machine guide rail respectively, the left end of the broaching rod stretches out and is fixed to the part outside the left end of the left bearing, the right end of the broaching rod stretches out of the right end of a broaching and clamping piece body, a broach fixing structure is arranged on the right connection sleeve, the left end of the right connection sleeve is connected with the broaching rod, an axial installation hole is formed in a positioning plate, and the right end of the positioning plate is connected with a worktable at the front end of the broaching machine.
Description
technical field [0001] The invention belongs to a jig for broaching an internal helical spline on a workpiece on a machine tool, in particular to a jig for broaching an internal helical spline on a common horizontal broaching machine. Background technique [0002] There is a workpiece 200 in some special machines, see figure 1 with figure 2 As shown, the workpiece is provided with an internal helical spline 201. The normal section size of the internal helical spline 201 is: Z=13, β=28°56′36″, left-handed, spline minor diameter φ23.8H11, large Diameter φ26.3H8, pitch circle diameter φ25㎜, tooth thickness 3±0.05×30°±10′. Since the internal helical spline 201 is helical with small inner hole and large lead (142.017㎜), the Usually, it cannot be processed on an ordinary horizontal broaching machine where the main shaft and the puller can only move in a straight line. Instead, the multi-head internal thread processing method is used to perform turning processing on the lathe. A...
