Detailed Description
As shown in fig. 1 and 2, the utility model discloses a anchor clamps for bevel gear A inspection includes: the clamp comprises a clamp body 1, a positioning disc 2, a pull rod 3 and an expansion sleeve 4, wherein the clamp body 1 is provided with a through hole 1a along the axial direction, and one part of the wall surface of the through hole 1a is a conical surface; the through hole 1a is a stepped hole, the conical surface is a part of the wall surface of the large-diameter hole of the through hole 1a, and the expansion sleeve 4 is positioned in the large-diameter hole of the through hole 1 a.
The positioning disc 2 is matched with the first end surface A1 of the bevel gear A, and the positioning disc 2 forms axial limit on the bevel gear A. After the positioning disc 2 is sleeved on the clamp body 1, the positioning disc 2 is connected with the clamp body 1; preferably, the outer circumferential surface of the clamp body 1 is provided with a flange 1b, and the positioning disc 2 is fixedly connected with the flange 1 b. The flange 1b is provided with a mounting hole, the positioning plate 2 is provided with an assembly hole, and the mounting hole on the flange 1b is in threaded connection after the connecting screw 5 penetrates through the assembly hole on the positioning plate 2, so that the positioning plate 2 and the flange 1b are fixed.
One end of the pull rod 3 penetrates through the through hole 1a of the clamp body 1 and is exposed outside the clamp body, one end of the pull rod 3 penetrates through the small-diameter hole of the through hole 1a, and the other end of the pull rod 3 extends into the through hole 1a of the clamp body 1, namely, the other end of the pull rod 3 is positioned in the large-diameter hole of the through hole 1 a. Since the through hole 1a is a stepped hole, the pull rod 3 is provided with a limiting part 1c which is matched with the step of the stepped hole when the pull rod moves, and preferably, the limiting part 1c is a nut which is connected to the pull rod 3 in a threaded manner. When the pull rod 3 moves, the pull rod can be prevented from being pulled transitionally through the matching of the limiting part 1c and the step of the step hole.
after the expansion sleeve 4 is sleeved on the pull rod 3, the expansion sleeve 4 is fixedly connected with the pull rod 3, and the expansion sleeve 4 is sleeved at the other end of the pull rod 3, so that the expansion sleeve 4 is positioned in the large-diameter hole of the through hole 1 a. A space 6 for inserting the end of the bevel gear is reserved between the expansion sleeve 4 and the pull rod 3, a part of the conical surface of the outer peripheral surface of the expansion sleeve 4 is matched with the conical surface of the through hole 1 a. When the pull rod 3 moves rightwards (seen from figure 2), the expansion sleeve 4 moves along with the pull rod 3, so that the conical surface of the through hole 1a presses the expansion sleeve 4, and the expansion sleeve 4 is forced to contract radially.
Still include stop screw 7, be equipped with on the pull rod 3 and supply stop screw male slot 3a, be equipped with radial screw hole 1d on the anchor clamps body 1, stop screw 7 with screw hole 1d threaded connection, the path hole clearance fit of a part and through-hole 1a of pull rod 3, consequently, if do not restrict pull rod 3, pull rod 3 can rotate, insert the slot 3a on the pull rod 3 through stop screw 7, can prevent like this that pull rod 3 from rotating by oneself.
