Detailed Description
Because the finishing punches 6 are uniformly distributed in the finishing die according to the circumference, the V-shaped positioning part 602 is inserted into the die center positioning block 2 to play a positioning role, the die center positioning block is provided with a high-precision positioning groove with the same number as the gear teeth, and the tooth-shaped forming part extrudes the tooth-shaped forming during punching and finishing so as to realize the finishing forming process of the inverted cone tooth shape; the consistency of the tooth distance and the tooth distance of the gear is important, if the finishing punch 6 has a position difference between a tooth profile forming part 601 and a V-shaped positioning part 602 (as shown in fig. 4), the formed tooth profile evaluation has a tooth profile error to cause that the gear cannot be normally used, so the precision of the finishing punch 6 is particularly important, and the finishing punch 6 needs to be detected in time when being processed to ensure the precision of the finishing punch 6; therefore, the tooth surface symmetry checking fixture for the finishing punch of the automobile gearbox combined with the teeth is designed, and the technical scheme of the utility model is explained in detail according to the attached drawings;
as shown in fig. 1-3, the checking fixture comprises a bottom plate 1, a positioning block 2 arranged on the bottom plate 1, a supporting block 3 connected with the positioning block 2, a display fixing seat 4 arranged on the supporting block 3, and an indicator 5 connected with the display fixing seat 4, wherein the display fixing seat 4 is pi-shaped, and because the supporting block 3 is higher than the positioning block 2, the part of the display fixing seat 4 which is vertical to the supporting block 3 is positioned above the positioning block 2; it should be noted that the whole gauge is symmetrically arranged.
In order to place the finishing punch 6 conveniently, the positioning block 2 is provided with a V-shaped groove 201 inwards on the surface far away from the supporting block 3, the V-shaped groove 201 is longitudinally formed, the size of the V-shaped groove 201 in the checking fixture is particularly important, the size of the V-shaped groove 201 needs to be matched with the size of a V-shaped positioning part 602 of the finishing punch 6 and needs to be consistent with the 30-degree V-shaped size of the finishing punch 6, when the finishing punch 6 is attached to the V-shaped groove 201, the top surface of the finishing punch 6 is parallel to the upper surface of the base plate 1 at the moment, the compacted finishing punch 6 cannot shake, and high repeatability of detection data is guaranteed.
In order to detect the finishing punch 6, three indicating tables 5 are arranged in the detection tool, the indicating tables 5 comprise measuring heads 501, the three measuring heads 501 penetrate through a pi-shaped indicating fixing seat 4, namely, through holes are formed in three edges of the indicating fixing seat 4, the three measuring heads 501 penetrate through the corresponding holes respectively and are in contact with the addendum circle and the two sides of the tooth surface of the tooth-shaped forming portion 601 in the finishing punch 6 for detection.
The connection mode of each part of the checking fixture is described below, positioning pins are adopted for positioning between the positioning block 2 and the bottom plate 1, between the indication fixing seat 4 and the supporting block 3 and between the supporting block 3 and the bottom plate 1, the positioning block 2 and the bottom plate 1 are fixedly connected through bolts, the indication fixing seat 4 and the supporting block 3 and between the supporting block 3 and the bottom plate 1 are fixedly connected through screws, and the indication gauge 5 and the indication fixing seat 4 are fixedly connected through fixing screws 7; the precision tolerance of the relative distance of the pin hole of the bottom plate 1 is +/-0.01, so that the relative distance between the finishing punch 6 and the measuring head 501 is fixed, and the repeatability of measured data is good.
The working principle is as follows: taking the first piece of the finishing punch 6 qualified in three-coordinate detection, placing the first piece in the V-shaped groove 201 of the positioning block 2, tightly attaching the first piece and the third indicating table 5, taking down the first piece, placing the finishing punch 6 to be detected in the V-shaped groove 201 of the positioning block 2, if the first piece and the finishing punch are tightly attached, determining that the V-shaped positioning part 602 of the finishing punch 6 is qualified, and if the size deviation is found, discarding the small size or matching the next batch with a corresponding correction inclined plane with the large size; after the finishing punch 6 is tightly attached to the positioning block 2, the entrance and exit of the tooth forming part 601 of the finishing punch are detected, the readings of the three indicating tables 5 are read respectively, the display values of the three indicating tables 5 are all below 0.01, namely, the finishing punch 6 is qualified, if the size deviation is found, the finishing punch is scrapped when the size is small or the finishing punch is assembled in the next batch, and the corresponding correction inclined plane with the large size is finally ensured to be consistent with the first piece; the detection time is greatly shortened by adopting the detection tool, the detection is carried out within 15-30 seconds, the manual operation is fast, after the first piece of workpiece is detected in three coordinates, the finishing punch 6 to be detected is detected by adopting a circular determination method, and the detection can be simply, conveniently and quickly carried out.
