Abstract

A tool for bisection of a shifting fork comprises a planar base, wherein the base is provided with a first threaded hole and a second threaded hole according to the angles of a first hole and a third hole of the shifting fork and the pitch of holes. Screw rods are spirally arranged in the first threaded hole and the second threaded hole respectively, each screw rod is sleeved with a locating pin for aligning and limiting the position of the shifting fork, a nut for pressing the shifting fork on the base is further connected to the upper end of each screw rod, and a rectangular knife withdraw groove for withdrawing a knife is formed in the middle position, corresponding to the second hole of the shifting fork, of the base. The tool for the bisection of the shifting fork has the advantages of being simple in structure, convenient to use, low in manufacturing cost, capable of achieving one-time clamping locating, repeatedly machining parts, saving a large amount of aligning time, and improving machining efficiency and machining precision of parts, not high in skill requirement of operators, and particularly suitable for batch production.

Description

A kind of for to the frock of cuing open shift fork

Technical field

The utility model relates to a kind of for to the frock of cuing open shift fork.

Background technology

Shift fork part, see shown in Fig. 1, Fig. 2, comprise body 1 ', the first hole 2 that described body 1 ' be above a provided with line arranges ', the second hole 3 ', the 3rd hole 4 ', it is for the gear of lathe, in lathe professional production enterprise, this part is batch production, and its machining accuracy will directly have influence on speed change positioning precision and the fluency of lathe in shift process.This just requires this part to have higher requirement on machining accuracy, but because the profile of shift fork part is irregular, area is again less, make in its second hole 2 ' locate to carry out to cuing open in cutting-off process, clamping and location are all more difficult, and man-hour is very low, and each renewal part, after all needing again centering location correct, cut off again, suitable trouble, and also need the operating personnel that industrial grade is higher, the input of enterprise is increased, very uneconomical.

Summary of the invention

The purpose of this utility model is to provide a kind of can cut off processing to the location of processing shift fork part fast and accurately, it is convenient to clamp, part is not yielding, and can significantly save a large amount of centering positioning times, shortened significantly process time, improved operating efficiency for to the frock of cuing open shift fork.

For reaching goal of the invention the technical solution adopted in the utility model be:

A kind of for to the frock of cuing open shift fork, it is characterized in that: comprise a flat base, on described base, be provided with the first screwed hole arranging according to angle and the pitch-row in shift fork the first hole and the 3rd hole, the second screwed hole, described the first screwed hole, in the second screwed hole, be all installed with screw rod, each described screw jacket is equipped with the alignment pin for centering and restriction shift fork position, the upper end of each described screw rod is also connected with shift fork is pressed on to the nut on base, on described base, be provided with a rectangular escape for cutter withdrawing at the centre position place in the second hole of corresponding shift fork.

Further, the width of described escape is less than the diameter in the second hole of described shift fork.

The course of work of the present utility model is as follows:

1, according to the position of setting, correctly screw rod, the each setting element of alignment pin are arranged on base.

2, put into the T-shaped groove of lathe with T-shaped nut, described in the utility model for the frock of cuing open shift fork being correctly arranged on to the workbench of lathe, play table with dial gauge and measure on to two measurement datums of the frock of cuing open shift fork described in the utility model, make described in the utility model for the frock of cuing open shift fork being reached to longitudinal, horizontal perpendicularity requirement.

3, described in the utility modelly for after the frock of cuing open shift fork is installed, the first hole of shift fork, the 3rd hole are arranged on respectively to alignment pin place, then by screwing nut, shift fork are pressed on base end face.

4, the cutter of the second hole top that are arranged at shift fork are shift fork to cutting, and left and right shift fork just can complete.

5, repeat above-mentioned steps 3 and step 4, just can continuously process left and right shift fork.

The beneficial effects of the utility model: simple in structure, easy to use, cost of manufacture is cheap, and clamped one time location, can repeat processing parts, save in a large number the time of centering, improved working (machining) efficiency, and improved the machining accuracy of part, meanwhile, less demanding to operator's technical ability.Spy is applicable in large batch of production process.
