Detailed Description
The utility model belongs to the technical field of automobile differential detects, concretely relates to differential mechanism differential side gear jump ring groove depth degree detection device. Most current differential half shaft gears of passenger cars (such as cars, SUVs, electric automobiles and the like) have the requirement of the distance between a clamp spring groove and a mounting surface, and the depth of the clamp spring groove limits the axial position of a half shaft. The utility model is used for during the jump ring groove 3 on the processing differential mechanism side gear 1, measure jump ring groove 3 and use when processing required degree of depth.
As shown in fig. 1-3, the device for detecting the depth of the jump ring groove of the differential half-axle gear comprises a detection tool body 4, wherein the upper end surface of the detection tool body 4 is parallel to the horizontal plane, and a detection pile 5 is fixedly arranged on the upper end surface of the detection tool body 4; the diameter of the detection pile 5 is matched with the diameter of the clamp spring groove 3 of the differential mechanism half shaft gear 1, namely the central axis of the differential mechanism half shaft gear 1 is coincided with the central axis of the detection pile 5. During detection, the differential side gear 1 can be directly placed on the detection pile 5, and the distance L from the mounting surface of the differential side gear 1 to the upper end surface of the detection tool body 4 is measured through a vernier caliper and a height gauge.
A circle of the upper end face of the detection pile 5 is a first chamfer, and the degree of an included angle alpha formed by the first chamfer and the central axis of the detection pile 5 is smaller than the degree of an included angle beta formed by the second chamfer at the bottom of the clamp spring groove 3 and the central axis of the detection pile 5. It can be understood that, because α < β, when the differential side gear 1 is placed on the detection pile 5, the groove bottom of the clamp spring groove 3 is just clamped on the first chamfer, and the distance L2 between the position where the groove bottom of the clamp spring groove 3 is clamped on the first chamfer and the upper end face of the gauge body 4 can be calculated.
When the differential side gear 1 is placed on the detection pile 5, one end face, close to the clamp spring groove 3, of the differential side gear 1 is separated from the upper end face of the detection tool body 4, and the diameter of the upper end face of the detection pile 5 is smaller than that of the inner hole 2 of the differential side gear 1, so that the differential side gear 1 is positioned when placed on the detection pile 5. The detection stake 5 is the customization piece, when processing the detection stake 5, only need control the height L3 of detection stake 5 (the distance of the up end of detection stake 5 to examining a body 4 up end promptly), the contained angle alpha that first chamfer and detection stake 5 axis were and the diameter D of the up end of detection stake 5, can learn through the calculation, L2's numerical value when the degree of depth of jump ring groove 3 is in standard or specified value, because L2 receives the injecing of three standard value and obtains, consequently L2 is fixed standard value, non-floating value.
The central position of detection stake 5 sets up the screw hole, the screw hole cooperatees with housing screw 7, set up gasket 6 between housing screw 7 and differential mechanism side gear 1, gasket 6 is the opening gasket. Compression screw 7 and opening gasket 6 all are used for fixed differential side gear 1 for differential side gear 1 closely laminates with detection stake 5, avoids rocking differential side gear 1 when measuring and leads to measuring error.
The specific working mode is as follows: the detection method comprises the following steps:
1. calculating the standard distance L2: determining the degree of an included angle alpha formed by the first chamfer on the upper detection pile 5 and the central axis of the detection pile 5 according to the degree of an included angle beta formed by the second chamfer at the bottom of the clamp spring groove 3 and the central axis of the detection pile 5; calculating to obtain a standard distance L2 according to the specified depth of the jump ring groove 3 to be processed, the included angle alpha formed by the first chamfer and the central axis of the detection pile 5 and the diameter D of the upper end face of the detection pile 5;
2. loading a workpiece: after the clamp spring groove 3 is machined, the differential half shaft gear 1 to be detected is installed on a detection pile 5 of the detection tool body 4, and the clamp spring groove hole is matched with the detection pile 5;
3. pressing the workpiece: then the opening gasket 6 is inserted into the compression screw 7, and the compression screw 7 is tightened to compress the half-axle gear;
4. measuring a workpiece: a depth vernier caliper or a height gauge is used for measuring the distance L (namely the distance between the mounting surface of the differential side gear 1 and the upper end surface of the gauge body 4) between the mounting plane of the side gear and the plane of the gauge body.
5. Calculating the distance L1 from the bottom of the clamp spring groove 3 to the installation plane of the differential side gear 1: l1 ═ L-L2; if the measured L value minus the L2 value is not within the depth range of the jump ring groove required by the drawing, the depth of the jump ring groove 3 is not up to the specified depth, and the adjustment processing is needed.
