Abstract

The invention discloses an external spline effective length gauge, which comprises a gauge body with a spline, a measuring plate, an extension rod, a meter chuck and a dial indicator. The extension rod is in sliding cooperation with the upper end of the gauge body and one side of the meter chuck. The measuring plate is disposed on the extension rod, at the upper end of the gauge body and at the outer side of the meter chuck. The measuring plate is in sliding cooperation with a connecting end of the extension rod. The dial indicator is connected with the other end of the meter chuck, and is also in transmission connection with the extension rod. The gauge body takes the diameter of a spline end point in a transition region of an external spline under test and an optical outer circle as the spline minor diameter of the gauge body. The invention is capable of quick and accurate on-site measurement of the effective length from an external spline slot to the spline end point in the transition region of the spline and the optical outer circle.

Description

A kind of male splines effective length cubing
Technical field
The present invention relates to a kind of cubing for measuring effective length between spline end point in male splines draw-in groove to spline and light cylindrical zone of transition.
Background technology
Splined is connecting mode important in mechanical drive.Along with the manufacturing develop rapidly taking auto industry as representative, to the demand of spline in continuous increase, simultaneously also more and more higher to the requirements of spline, to the test item of spline also in continuous increase.At present, for the measurement of the effective length in male splines draw-in groove to spline and light cylindrical zone of transition between spline end point, adopt general universal check tool due to the spline end point in zone of transition cannot be found, thus also cannot meet measurement requirement.And although three-dimensional can be measured, because consuming time, on-the-spot requirement of measuring in enormous quantities fast cannot be met.
Summary of the invention
Technical matters to be solved by this invention be to propose a kind of can at the scene fast, the cubing of effective length between spline end point in Measurement accuracy male splines draw-in groove to spline and light cylindrical zone of transition.
For solving the problems of the technologies described above, a kind of male splines effective length of the present invention cubing comprises measurer body, drafting board, extension bar, table chuck and the indicating gauge of being with spline, described extension bar is slidably matched with the upper end of described measurer body and the side of described table chuck respectively, described drafting board is located on described extension bar, the outside of described measurer body upper end and described table chuck, and the link of described drafting board and described extension bar is slidably matched; Described indicating gauge is connected to the other end of described table chuck, and is connected with described extension bar transmission; Described measurer body is using the diameter of spline end point in tested male splines and light cylindrical zone of transition as the spline path of measurer body.
Above-mentioned a kind of male splines effective length cubing, it also includes spacing collar and screw, and described spacing collar is fixed on the link of described extension bar by described screw, the outside of described drafting board.
Above-mentioned a kind of male splines effective length cubing, it also includes clamping ring, and described clamping ring is located at the junction of described indicating gauge and table chuck.
The present invention is owing to have employed above-mentioned technical pattern, during measurement, the diameter contact of spline end point in first throughput concrete spline path and tested male splines and light cylindrical zone of transition, carry out measurement and positioning, and then promote drafting board in workpiece draw-in groove, unclamp drafting board, drafting board is leaned against on draw-in groove inwall automatically.Like this, just by extension bar, coverage is delivered on dial gauge, realizes quick and precisely measuring.
Accompanying drawing explanation
Fig. 1 is the Workpiece structure schematic diagram adopting cubing of the present invention to measure;
Fig. 2 is the outer shape schematic diagram of A-A end spline in Fig. 1;
Fig. 3 is the structural representation of cubing of the present invention;
Fig. 4 is the detection schematic diagram adopting cubing of the present invention.
Embodiment
As depicted in figs. 1 and 2, adopt the measured workpiece 10 that cubing of the present invention is measured, measurement be the effective length L of spline end point in its male splines draw-in groove to spline and light cylindrical zone of transition B, D represents the diameter of spline end point.
As shown in Figure 3, cubing of the present invention comprises the band measurer body 1 of spline, spacing collar 2, drafting board 3, extension bar 4, table chuck 5, clamping ring 6, screw 8, indicating gauge 7(dial gauge) assembly forms.Because measured workpiece 10 is objects based on male splines, thus measurer body 1 is with the Parameter of spline of tested spline for foundation, and its lower end exists with the form of female spline.The spline of measurer body 1 and the spline of measured workpiece 10 can not be interfered, and in the male splines of measured workpiece 10 and light cylindrical zone of transition B, the diameter D of spline end point is as the spline path of measurer body 1.During measurement, in the concrete 1 spline path of throughput and measured workpiece 10 male splines and light cylindrical zone of transition B, the diameter contact of spline end point, plays measurement and positioning effect.
Extension bar 4 is slidably matched with the side showing chuck 5 with the upper end of measurer body 1 (what present embodiment adopted is first be connected with the upper end of measurer body 1 side showing chuck 5, and the side that then chuck 5 shown by extension bar 4 is slidably matched), can transmit coverage.Extension bar 4 must be little with measurer body 1 and the tolerance clearance showing chuck 5, otherwise may affect measurement accuracy.
Drafting board 3 is located on extension bar 4, the outside of measurer body 1 upper end and table chuck 5, and drafting board 3 is slidably matched with the link of extension bar 4.Spacing collar 2 is fixed on the link of extension bar 4 by screw 8, the outside of drafting board 3, make the 360 ° of rotations of drafting board 3 energy, but front and back can not be rocked.The accuracy that can affect measurement is rocked in front and back.
Indicating gauge 7 is connected to the other end of table chuck 5 by clamping ring 6, and is connected with extension bar 4 transmission.By showing the conventional means that the mode of being in transmission connection of chuck 5 is existing field of measuring technique between indicating gauge 7 and extension bar 4, repeat no more herein.
As shown in Figure 4, during measurement, in the concrete 1 spline path of throughput and measured workpiece 10 male splines and light cylindrical zone of transition B, the diameter contact of spline end point F, promotes in the draw-in groove of drafting board 3 to measured workpiece 10 male splines.Unclamp drafting board 3, make drafting board 3 automatically lean against draw-in groove inwall, by extension bar 4, coverage is passed on indicating gauge 7, thus realize quick and precisely measuring.
