DESCRIPTION
TOOLING FOR LINEARLY CUTTING INTERNAL SPLINES OF INPUT PLANET CARRIERS WHICH IS CONVENIENT FOR COMPRESSING A
WORKPIECE
Technical Field of the Invention
The present invention relates to a tooling for linearly cutting internal splines of input planet carriers which is convenient for compressing a workpiece.
Background of the Invention
In the prior art, in order to linearly cut internal splines of input planet carriers, each input planet carrier needs to be fixed. The input planet carriers are machined successively by linear cutting, and it is unable to machine internal splines of a plurality of input planet carriers in one time. Therefore, the machining efficiency is low.
Summary of the Invention
An objective of the present invention is to provide a tooling for linearly cutting internal splines of input planet carriers which is convenient for compressing a workpiece, by which a number of input planet carriers are simultaneously machined by linear cutting.
For this purpose, the present invention employs the following technical solutions: a tooling for linearly cutting internal splines of input planet carriers which is convenient for compressing a workpiece is provided, including a chassis, a positioning sleeve and a gland, the chassis, the positioning sleeve and the gland being three independent components; a central positioning hole running through the chassis from top to bottom is formed on the chassis; an 1 inner cavity for accommodating several input planet carriers to be cut is formed within the positioning sleeve; an inner edge of a radial cross-section of the positioning sleeve is circular; the inner cavity of the positioning sleeve and the central positioning hole of the chassis are arranged coaxially; a through hole running through the gland from top to bottom is formed on the gland; several input planet carriers to be cut are stacked within the inner cavity, with the position of an upper end face of the topmost input planet carrier to be cut being higher than the position of an upper end face of the positioning sleeve and the position of a lower end face of the topmost input planet carrier to be cut being lower than the position of the upper end face of the positioning sleeve; a lower end face of the gland extends upward to form a circular groove communicated with the through hole; and, when the gland and the positioning sleeve are fixed, the upper end face of the topmost input planet carrier to be cut is located within the circular groove; the value of the height from the upper end face of the topmost input planet carrier to be cut to a lower end face of the bottommost input planet carrier to be cut is greater than or equal to a sum of the value of the height of the inner cavity of the positioning sleeve and the value of the depth of the circular groove. In such an arrangement, it is convenient for the gland to compress the pieces to be cut, and the occurrence of a gap between the lower end face of the gland and the pieces to be cut is avoided. 2017100748 15 Jun2017
In use of the tooling of the present invention, the positioning sleeve and the chassis are fixed first, and a plurality of pieces to be cut (input planet carriers to be cut) are then placed into the cavity of the positioning sleeve. The topmost piece to be cut is partially exposed out from the positioning sleeve. The axial limiting to the pieces to be cut is realized by fitting the circular groove of the gland and the topmost piece to be cut, and the radial limiting to the pieces to be cut is realized by the inner cavity of the positioning sleeve. By applying a force to the gland, the pieces to be cut are compressed tightly, and then linearly cut and machined. Before linear cutting, a metal wire is passed through the central positioning hole of the chassis, the through holes of several 1 pieces to be cut and the through hole of the gland, and then to a central position of the inner cavity of the positioning sleeve through the central positioning hole, so that the concentricity for the axes of several pieces to be cut after being machined is ensued. 2017100748 15 Jun2017
In the present invention, a plurality of pieces to be cut (input planet carriers to be cut) can be linearly cut and machined in one time, so that the machining efficiency is high; moreover, the axial precision of the pieces to be cut may be ensured, and the machining precision is thus high.
Brief Description of the Drawings
Fig. 1 is a structural diagram of the present invention; and
Fig. 2 is a structural diagram of the present invention, when fitted with pieces to be cut.
Detailed Description of the Invention
The present invention will be further described below by specific embodiments with reference to the accompanying drawings.
As shown in Figs. 1 and 2, the present invention provides a tooling for linearly cutting internal splines of input planet carriers, including a chassis 1, a positioning sleeve 2 and a gland 3, wherein the chassis 1, the positioning sleeve 2 and the press cover 3 are three independent components; a central positioning hole 11 running through the chassis from top to bottom is formed on the chassis 1; an inner cavity for accommodating several input planet carriers 4 to be cut is formed within the positioning sleeve 2; an inner edge of a radial cross-section of the positioning sleeve 2 is circular; the inner cavity of the positioning sleeve 2 and the central positioning hole 11 of the chassis 1 are arranged coaxially; and, a through hole 31 running through the gland from top to bottom is formed on the gland 3.
In the present invention, the inner cavity of the positioning sleeve 2 is used for accommodating four input planet carriers 4 to be cut which are stacked 3 from top to bottom. When the four input planet carriers 4 to be cut, which are stacked from top to bottom, are placed into the inner cavity, the position of an upper end face of the topmost input planet carrier 4 to be cut is higher than the position of an upper end face of the positioning sleeve 2, and the position of a lower end face of the topmost input planet carrier 4 is lower than the position of the upper end face of the positioning sleeve 2. A lower end face of the gland 3 extends upward to form a circular groove communicated with the through hole31. When the gland 3 and the positioning sleeve 2 are fixed, the upper end face of the topmost input planet carrier 4 to be cut is located within the circular groove 32. The value of the height from the upper end face of the topmost input planet carrier 4 to be cut to a lower end face of the bottommost input planet carrier 4 to be cut is denoted by Li, the value of the height of the inner cavity of the positioning sleeve 2 is denoted by L2, the value of the depth of the circular groove 32 is denoted byL3, and Li is greater than the sum of L2 and L3. A boss 41 is formed on an end face of each of the input planet carriers 4 to be cut, and the inner diameter of the through hole 31 of the gland 3 is greater than the outer diameter of the boss 41. 2017100748 15 Jun2017
The gland 3 is fixed with the positioning sleeve 2 through three first screws 5, three fitting holes 51 for fitting the first screws 5 are formed on both the gland 3 and the positioning sleeve 2, and an internal thread structure is formed within each of the fitting holes 51 of the positioning sleeve 2. The three fitting holes of the positioning sleeve 2 and the three fitting holes of the gland are annularly and uniformly arranged at intervals around an axis of the central positioning hole 11 of the chassis.
All the upper end face of the positioning sleeve 2, the lower end face of the positioning sleeve 2, the upper end face of the chassis 1 and the lower end face of the chassis 1 are flat, and both the upper end face and the lower end face of the positioning sleeve 2 are arranged perpendicularly to the axis of the positioning sleeve 2. The positioning sleeve 2 and the chassis 1 are fixed by three second screws 6, a fitting hole for fitting a positioning pin 7 is formed on 4 both the positioning sleeve 2 and the chassis 1, and the fitting hole of the positioning sleeve 2 corresponds to the fitting hole of the chassis 1. 2017100748 15 Jun2017 5
