Description
Technical Field
The utility model relates to a ring gear precision measurement technical field especially relates to a frock for measuring thin wall spare ring gear precision.
Background
When the accuracy of the ring gear is measured, the deformation of the ring gear made of different materials is different, for example, a ring gear thin-wall part made of 18CrMo7-6 material is easy to deform, in the actual detection process, the positioning mode of detecting the ring gear is three-jaw positioning, for the ring gear which is easy to deform, the condition of tooth direction swing out of tolerance can occur in the detection process, the measurement difficulty is increased, and the measurement result is inaccurate and needs to be improved.
Disclosure of Invention
The utility model discloses aim at solving prior art not enough, and provide a frock for measuring thin wall spare ring gear precision.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
the utility model provides a frock for measuring thin wall spare ring gear precision, includes the positioning disk, is fixed with a plurality of locating piece on the positioning disk, and a plurality of locating piece equipartition is in positioning disk circumference, and the ascending arch in locating piece middle part, bulge have seted up along the radial adjusting hole of positioning disk, and the adjusting hole internal rotation is equipped with adjusting bolt, is equipped with a plurality of rows along the radially distributed locating hole of positioning disk between the adjacent locating piece, has the cylinder locating pin in the locating hole, has still seted up a plurality of lifting eye on the positioning disk.
At least four positioning blocks are arranged.
And the middle part of the positioning plate is provided with a lightening hole.
The utility model has the advantages that: the utility model discloses a positioning disk is the foundry goods, and stability is good, is difficult to warp. The length of the adjusting bolt and the position of the positioning block can be adjusted according to the size of the gear ring to be measured. The tool is used for measuring the gear ring which is easy to deform, the gear ring cannot swing in the tooth direction, the measurement is easy, and the measurement result is accurate.

in the figure: 1-adjusting the bolt; 2-positioning blocks; 3-positioning the disc; 4-positioning bolts; 5-positioning holes; 6-lifting holes; 7-lightening holes; 8-adjusting holes;
the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1 to 2, the tool for measuring the precision of the ring gear of the thin-wall member comprises a positioning disc 3, and four positioning blocks 2 are fixed on the positioning disc 3.
The positioning block 2 is fixed on the positioning plate 3 through a positioning bolt 4.
Four locating blocks 2 are uniformly distributed on the periphery of the locating disc 3.
The middle part of the positioning block 2 is upwards protruded, the protruding part is provided with an adjusting hole 8 along the radial direction of the positioning disc 3, an adjusting bolt 1 is screwed in the adjusting hole 8, the tail end of a screw rod of the adjusting bolt 1 is a copper head, and the copper head is prevented from scratching the gear ring when the gear ring is propped against the gear ring.
A plurality of rows of positioning holes 5 distributed along the radial direction of the positioning disc 3 are arranged between the adjacent positioning blocks 2, and cylindrical positioning pins are arranged in the positioning holes 5.
The positioning plate 3 is also provided with a plurality of lifting holes 6.
The middle part of the positioning plate 3 is provided with a lightening hole 7.
The utility model discloses when using, at first install positioning disk 3 on the three-jaw chuck of tooth appearance, hole alignment is adjusted positioning disk 3 to the center after on installing positioning disk 3 with the ring gear, then according to the size of ring gear, inserts the cylinder locating pin in locating hole 5 and tentatively fixes a position. After the gear ring is placed, the adjusting bolt 1 is screwed, so that the copper head of the adjusting bolt 1 is abutted to the gear ring, the position of the gear ring is adjusted, the purpose of accurate alignment is achieved, and the accuracy of the gear ring can be detected after the alignment is observed according to a gear measuring instrument.
The utility model discloses a positioning disk 3 is the foundry goods, and stability is good, is difficult to warp.
The length of the adjusting bolt 1 and the position of the positioning block 2 can be adjusted according to the size of the gear ring to be measured.
The tool is used for measuring the gear ring which is easy to deform, the gear ring cannot swing in the tooth direction, the measurement is easy, and the measurement result is accurate.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
