Abstract

The patent discloses a bearing inner race auxiliary processing clamping device, including lead screw, ring shape support frame, blotter, track, rotation handle, connecting block, can be used to control the not bearing inner race of equidimension of centre gripping in order to process the inner race, this patent has simple structure characteristics easy and simple to handle, and the damage to the bearing inner race among the reducible centre gripping process can be more stably the centre gripping in order to conveniently process the inner race of bearing.

Description

Bearing inner race auxiliary machining clamping device

Technical Field

The patent relates to an anchor clamps, concretely relates to supplementary processing clamping device of bearing inner race.

Background

When the bearing inner ring is machined, the bearing inner ring is easy to fall off from the fixing device, so that the machining precision of the bearing inner ring is insufficient, and the efficiency of machining the bearing inner ring is influenced.

Disclosure of Invention

The patent discloses a bearing inner race auxiliary processing clamping device's technical scheme is: four through-holes of evenly distributed on a ring shape support frame, through-hole inside weld has threaded track, and the screw thread cooperatees with the screw thread of lead screw, track length is greater than the ring shape support frame through-hole degree of depth and nevertheless is less than the half of lead screw length, through rotatory handle, make the lead screw along track radial movement, lead screw one end is connected with the connecting block, the connecting block has the depth and does not exceed the three-quarter's of length deep hole, have in the deep hole with lead screw matched with screw thread, the connecting block links firmly with glue for the blotter, through rotatory handle, can make lead screw radial movement, make blotter and bearing inner race complete contact, thereby reach the purpose of.

Drawings

Fig. 1 is a schematic structural view of a clamping device for auxiliary machining of a bearing inner ring.

In the figure: 1 lead screw, 2 ring shape support frames, 3 blotters, 4 tracks, 5 twist grips, 6 connecting blocks.

Detailed Description

This patent is discussed below in terms of examples in the drawings of this patent.

Referring to the attached drawings, the novel screw rod supporting device is provided with a circular ring-shaped supporting frame (2), four through holes are uniformly distributed in the circular ring-shaped supporting frame (2), a track (4) is welded in the through holes, threads which can be completely matched with a screw rod (1) are arranged on the track (4), and the length of the track (4) is larger than the depth of the through holes of the circular ring-shaped supporting frame (2) but is smaller than one half of the length of the screw rod (1). Have rotation handle (5) on lead screw (1), connecting block (6) inside has a degree of depth and does not exceed the deep hole of connecting block (6) degree of depth three quarters, and inside has with lead screw (1) matched with screw thread, and connecting block (6) link firmly through glue with blotter (3). When the bearing inner ring is clamped, the center of the bearing inner ring is roughly placed to coincide with the center of the circular ring-shaped support frame (2), four rotating handles (5) are respectively rotated to enable the screw rod (1) to radially contract, at the moment, the screw rod (1) is adjusted to be incompletely matched with a deep hole of the connecting block (6), the depth of the deep hole is about one fourth of the length of the connecting block (6), the rotating handles (5) are continuously rotated to enable the buffer cushion (3) to be just contacted with the bearing inner ring, at the moment, the connecting block (6) is rotated to adjust the buffer cushion (3) to the position with the maximum contact area shown in the figure, the buffer cushion (3) is directly contacted with the connecting block (6) and the bearing inner ring, then the connecting block (6) is relatively static, the rotating handles (5) are rotated to enable the buffer cushion (3) to be closely contacted with, the device can be arranged on a triangular chuck to serve as an auxiliary device, and the clamping jaws of the chuck are required to be kept away from the screw rod during installation.

Claims

1. A clamping device for auxiliary machining of a bearing inner ring is characterized by comprising a lead screw (1), an annular support frame (2), a cushion pad (3), a track (4), a rotating handle (5) and a connecting block (6); four through holes are uniformly distributed on the circular support frame (2), a track (4) is welded inside each through hole, and threads matched with the lead screw (1) are arranged inside each track (4); the connecting block (6) is provided with a deep hole, threads are arranged in the deep hole and can be matched with the screw rod (1), and the connecting block (6) is fixedly connected with the cushion pad (3) by glue; the cushion pad (3) is strip-shaped and made of wear-resistant rubber.

2. The clamping device for auxiliary processing of the inner ring of the bearing is characterized in that the depth of the hole of the connecting block (6) is more than or equal to three quarters of the height of the connecting block (6).

3. The clamping device for auxiliary processing of the inner ring of the bearing is characterized in that the length of the track (4) is greater than the depth of a through hole of the circular ring-shaped support frame (2) and less than half of the length of the screw rod (1).
