Description

Gearbox main four thrust washers arc groove processing device

Technical field:

The utility model relates to a processing device for circular arc grooves of four main thrust washers for a gearbox.

Background technique:

Primary four thrust washers are widely used in automotive gearboxes. At present, traditional processing equipment and processing methods are usually still used. The disadvantages of this processing method are:

Use an end mill with an appropriate diameter, and then tilt the end mill head at a certain angle (need to be determined by calculation, under the condition of ensuring the size and depth of the arc notch). In actual processing, this part (a total of 8 arc grooves on both sides) can only process 30 pieces a day, and the milling cutter needs to be replaced at least twice a day, so the processing efficiency is low.

Invention content:

The technical problem to be solved by the utility model is to overcome the above-mentioned deficiencies in the prior art, and provide a main four-thrust washer arc groove processing device for gearboxes with high processing efficiency and low labor intensity.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a main four-thrust washer arc groove processing device for a gearbox, which is characterized in that it includes a bottom plate, an equal plate, a cover plate, a positioning pin, a positioning seat, a positioning Boards, backing plates and positioning posts. The bottom plate is installed on the middle carriage of the lathe, the bottom plate is installed on the equalizing plate through bearings, the positioning seat is fixedly connected with the bottom plate, the cover plate is set on the positioning pin, the positioning plate and the positioning column are installed on the equalizing plate, and the parts to be processed are installed Between the positioning plate and the backing plate.

The equal division plate described in the utility model adopts four equal division divisions, and there are two parts to be processed.

The utility model has the following advantages and effects: the use of equal parts for positioning improves the precision of the product and the production efficiency; the tool is made of hard alloy material with good toughness and impact resistance, and the tool can be repaired at the same time, thereby saving costs.

Description of drawings:

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Fig. 2 is a structural schematic diagram of the main four thrust washers of the embodiment of the utility model.

Detailed ways:

Referring to Fig. 1 and Fig. 2, the main four-thrust washer circular arc groove processing device for the gearbox of the embodiment of the utility model includes a bottom plate 7, an equal disc 11, a cover plate 10, a positioning pin 8, a positioning seat 9, and a positioning plate 12 , Backing plate 15, compression screw 16 and positioning column 17. In the utility model, the small carriage is removed from the C6140 machine tool, and the bottom plate 7 is installed on the middle carriage 4, and the quartering plate 11 is movably installed on the bottom plate 7 through the bearing 6, and the equal plate 11 can rotate together with the bearing. The positioning seat 9 is fixedly connected with the base plate 7 , the cover plate 10 is sleeved on the positioning pin 8 , and the positioning plate 12 and the positioning column 17 are installed on the aliquot plate 11 . A part 13 to be processed is respectively housed between the upper and lower positioning plates 12 and the backing plate 15 of the positioning column 17, the backing plate 15 is covered and tightened with the positioning screw 16, the diameter of the cutter is the same as the arc diameter of the processed part 13, and adjusted Good central high position, make the circular arc depth that two parts 13 process up and down are consistent. Like this, just can start to carry out turning processing, automatically feeds large carriage, and turning first arc groove 131, after first arc groove 131 car is finished, unclamps the pressing plate and positioning pin 8 on the bisecting plate 11 1. Rotate the equalizing disc 11 together with the processing parts 13 by 90°, lock the positioning pin 8 and press the upper platen of the equalizing disc 11, repeat the above steps until each of the four arc grooves 131 of the two parts 13 is processed.

In the embodiment of the utility model, the main four thrust washer parts are processed on the C6140, and the output can be more than 60 pieces a day, and the actual production efficiency is increased by more than 100%. Since the cutter head is made of hard alloy material, the cutter can be used repeatedly after being ground like a common turning cutter after being worn out, thereby greatly saving the cost of the cutter.
