Problems solved by technology

This method has a large error in alignment and alignment. Usually, the error of tool alignment on the circumference will reach 1-2.5mm. For the case of high requirements for the circumferential angle position of the tooth groove, it cannot accurately meet the requirements, that is, this alignment method. There are disadvantages of poor precision and poor practicability

Embodiment 1

[0043] figure 1 with figure 2 The first embodiment of the present invention is schematically given, which discloses a tool for determining the starting position of the gear shaper cutter, including:

[0044] The first round bar 210 is arranged in the first tooth groove 110 of the gear shaping cutter 100 and is tangent to the two side walls of the first tooth groove 110;

[0045] The second round rod 220 is arranged in the second tooth groove 120 adjacent to the first tooth groove 110 on the gear shaping cutter 100, and is tangent to the two side walls of the second tooth groove 120. The second round rod 220 is connected to the second tooth groove 120. The diameters of the first round rods 210 are the same;

[0046] The centering device 300 includes a rod body 310 and a positioning disc 320. The positioning disc 320 is provided with a guide hole 321 matching the rod body 310. The rod body 310 passes through the guide hole 321. A pointer is provided at the center of one end o...

Embodiment 2

[0062] In this embodiment, the tooling for determining the starting position of the gear shaping cutter is the same as that in the above-mentioned first embodiment. The difference is that this embodiment is used for the positioning of the internal gear. The main differences are:

[0063] Such as Figure 9 As shown, in this embodiment, the center line of the tooth groove is drawn on the inner ring end face of the gear workpiece 500 to be processed (instead of the outer ring end face in the first embodiment above), so as to realize the positioning of the inner gear processing . Such as Figure 10 As shown, the direction of the alveolar centerline 510 of the gear workpiece 500 to be processed to the alignment pointer 330 is different from that of the above-mentioned first embodiment, and other than that, the others are the same as those of the above-mentioned first embodiment, and are not mentioned here. Let me repeat them one by one.

[0064] In addition, in the present inven...

Abstract

The invention discloses a tool for determining the starting cutter position of a slotting cutter. The tool comprises a first round bar, a second round bar and a centralizer, wherein the first round bar is arranged in a first tooth groove of the slotting cutter and is tangent to both side walls of the first tooth groove; the second round bar is arranged in a second tooth groove, which is adjacent to the first tooth groove, in the slotting cutter and is tangent to both side walls of the second tooth groove, and the diameter of the second round bar is the same as that of the first round bar; the centralizer comprises a rod body and a positioning disc, a guide hole which is matched with the rod body is formed in the positioning disc, the rod body passes through the guide hole, a pointer is arranged in the center of one end of the rod body, the other end of the rod body extends between the first round bar and the second round bar and is provided with a first positioning surface and a second positioning surface which are symmetrically formed, the first positioning surface is tangent to the first round bar, the second positioning surface is tangent to the second round bar, and the positioning disc is respectively tangent to the first round bar and the second round bar. The tool has the advantages of precision in counterpointing and strong practicability.

Description

technical field [0001] The invention relates to a tool for slotting machines, in particular to a tool for determining the starting position of a gear shaping cutter and a positioning method thereof. Background technique [0002] Gear shaping machine is a kind of metal cutting machine tool. It is a gear processing machine tool that uses gear shaping cutters to process internal, external spur gears, helical cylindrical gears and other tooth-shaped parts according to the generation method. It is widely used in industrial production, especially It is the processing of gear workpieces. [0003] In the prior art, before the gear shaping machine is processed, one tooth of the gear shaping cutter must be aligned with the workpiece. Generally, a generatrix is ​​drawn on the outer circle or end surface of the tooth of the gear. The two sides of the busbar are equal, then insert and cut the gnawing mark, observe the gnawing mark, and adjust to make the starting tooth edge symmetrical ...
