In order to ensure the accuracy of the tooth alignment and avoid errors caused by artificial reasons during clamping, a tooth gauge is usually designed on a clamp to angularly position the intermediate shaft gear. The principle of a traditional tooth gauge mechanism is shown in fig. 1, an eccentric shaft structure is adopted for a tooth gauge, an eccentric shaft 2 drives an insert 1 to do linear motion when rotating, then the insert 1 drives a tooth gauge tip 3 to move, and when the tooth gauge tip 3 is meshed with a gear reference circle, the eccentric shaft 2 is self-locked to complete angular positioning. Because the key groove and the tooth groove have unique corresponding relation, when the teeth are aligned, the tooth gauge tip 3 is required to be clamped in the specified tooth groove, and the upper surface and the lower surface of the tooth gauge tip 3 are required to be meshed with the reference circle of the gear; meanwhile, a pre-positioning mechanism is required to be designed, and a pre-positioning tip 4 in the pre-positioning mechanism is used for guiding and preventing errors, so that the tooth gauge is assisted to align the teeth.

Above-mentioned scheme has two drawbacks, at first need calculate the value of eccentric shaft 2 eccentricity according to the degree of vibrations during processing, mainly relies on experience to obtain at present, can't the ration calculate, and eccentric shaft 2 processing degree of difficulty is great, has improved the manufacturing cost of anchor clamps. Secondly, the pre-positioning mechanism and the tooth aligning mechanism are required to be designed simultaneously, so that the weight of the clamp is increased, the clamp is not beneficial to field operation and carrying, and the clamp is inconvenient to replace.

Further, the locking mechanism is a set screw.

The utility model has the advantages that:

1. the utility model designs the tooth gauge center into a U-shaped structure, the U-shaped structure is provided with two centers, one of the centers is used for aligning teeth, and the middle shaft gear tooth socket which has unique corresponding relation with the key groove to be processed is clamped, thereby carrying out angular positioning; the other tip is used for pre-positioning, and the other middle shaft gear tooth grooves which are in position relation with the middle shaft gear tooth grooves are matched (not contacted with the tooth grooves), so that the error-proofing function is realized; when the U-shaped tip is meshed with the intermediate shaft gear, the set screw is screwed down, and the tooth aligning operation is very convenient.

2. The utility model discloses need not additionally to set up prepositioning mechanism when using, alleviateed the weight of anchor clamps, the field operation and the transport of being convenient for.

3. The utility model discloses in coordinate with angular seat (H7/g6) the top U type groove of tooth gauge, utilize the angular seat to lead to the apex, make the apex make linear motion all the time, guaranteed the precision of angular positioning.

4. Compare in traditional to the tooth rule, the utility model discloses it is easier to process, and the manufacturability is better, and anchor clamps are more stable in the use, have reduced the manufacturing cost of anchor clamps effectively.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 2 and 3, the tooth aligning gauge provided by the invention comprises a U-shaped tip 9 and an angular seat 8.

Two arms of the U-shaped center 9 are respectively used as a tooth crest 91 and a pre-positioning center 92; the tooth crest 91 is used for carrying out angular positioning on the teeth; the pre-positioning tip 92 is used for pre-positioning; the axial line of the tooth crest 91 is parallel to the axial line of the pre-positioning tip 92, and the distance between the tooth crest and the pre-positioning tip is consistent with the axial distance between two middle shaft gears which need to be matched when in tooth alignment.

The angular seat 8 is used for guiding the U-shaped center 9 when the U-shaped center 9 moves forwards and backwards; in order to improve the angular positioning precision, the angular seat 8 and the U-shaped tip 9 are matched by H7/g 6. When the tooth top 91 and the pre-positioning tip 92 are adjusted in place, namely the tooth grooves of the intermediate shaft gear are tightly pressed against the tooth top 91, and the pre-positioning tip 92 extends into the tooth grooves of the other intermediate shaft gear but does not contact the bottom and the inner wall of the tooth groove, the U-shaped tip 9 can be locked by a locking mechanism (such as a set screw 10) so that the position of the U-shaped tip is fixed.

Considering that when the centers at the two ends of the fixture lock the middle shaft to be machined, the positions of the middle shaft gears (such as the second row of teeth shown in fig. 2 in the embodiment) on different middle shafts, which have unique corresponding relations with the key grooves to be machined, on the fixture can be different, and in order to improve the compatibility with the tooth gauge, the angle seat 8 of the utility model is installed on the fixture bottom plate 5 through the sliding base 7; the angular seat 8 is arranged on the sliding base 7 and can slide along the axial direction, so that the sliding base is suitable for more different products; the sliding base 7 and the clamp bottom plate 5 are fixed through a positioning pin and then fixed through bolts, and an adjusting gasket 6 is arranged between the sliding base 7 and the clamp bottom plate 5.

In order to prevent cutting chips in the machining process from entering between the angular seat 8 and the U-shaped tip 9, a gland 11 is further arranged above the angular seat 8 and the U-shaped tip 9.

As shown in fig. 4, for utilizing the utility model discloses carry out the flow chart to the tooth, will take the place of processing the jackshaft centre gripping on V type piece, with the tight back of locking in tailstock top, adjust the utility model discloses to the top 9 of U type in the tooth gauge, block respectively at two jackshaft gear teeth inslot to tooth top 91 and pre-position top 92 with two arms of the top 9 of U type, then tighten holding screw 10, accomplish the angular positioning promptly, at this moment, can begin to process the jackshaft keyway, treat that processing is accomplished the back, loosen holding screw 10, it can to adjust the gear teeth groove that the top 9 of U type breaks away from the jackshaft.
