Abstract

The invention relates to the field of rollers or shafts of mechanical engineering, in particular to a roller group hole pattern machining device and method. The roller group hole pattern machining device comprises a forming cutter arranged on a lathe and provided with a reference surface and a measuring tool fixedly arranged on a measuring plate, a fixed measuring foot on the measuring tool is positioned at one end of a scribing ruler, the foot type of the fixed measuring foot is downward, a movable measuring foot is sleeved on the scribing ruler, and the foot type of the movable measuring foot is upward. The method for machining hole patterns by using the device comprises the following steps of: firstly, calculating the size of A2 (A-A2=A2), moving the measuring plate in the horizontal direction so that the movable measuring foot is propped against the reference surface of a roller, and reading the A2 on the scribing ruler; secondly, moving a machine tool holder so that the reference surface of the forming cutter is propped against the fixed measuring foot, namely the size (A1+A2=A) from the reference surface of the roller to the base line of the hole patterns is ensured; and finally, feeding the cutter, and machining the hole patterns. By using the device and the method, the machining precision and the machining efficiency can be improved, and the cost can be saved.

Description

Roll is pass processing unit (plant) and method thereof in groups

Technical field

The present invention relates to mechanical engineering roller, axle field, particularly a kind of roll is pass processing unit (plant) and method thereof in groups.

Background technology

Metallurgical roller is the important spare part of milling train, also is consumable accessory, and its body of roll cylindrical needs to process various live passes according to the demand of differential profiles, is the critical process in the Roller Machining.

Traditional pass processing method as shown in Figure 1, it adopts the roller frame, be about to two roll (working roll and counter roller) framves that match mutually on the roller frame, roller is erected the effect of stationary roll, pass with a roll (working roll) is a benchmark then, the moulding cutter processes the pass of working roll along the feed of pass boundary line, uses the pass that the type model is added the method processing another roll (counter roller) of range estimation then.Adopt this traditional processing unit (plant) and method thereof to cause following problem easily: at first, the mode of range estimation makes locating accuracy very low; Secondly, the roll of different size needs to make in addition the roller frame, and the expense of making the roller frame generally needs 10,000～20,000 yuan, will cause cost to increase like this, and frequent roll change frame has more influenced the efficient of processing again.

In order to overcome above-mentioned defective, be necessary the pass processing mode of this traditional approach is improved.

Summary of the invention

The objective of the invention is to, the roll that provides a kind of and can improve machining accuracy and working (machining) efficiency, can save cost is pass processing unit (plant) and method thereof in groups.

The objective of the invention is by adopting following technical scheme to realize:

A kind of roll is the pass processing unit (plant) in groups, comprises molding cutter and measuring tool that is fixedly installed on the measurement plate of the band datum level that is installed on the lathe, and the distance of the datum level of the molding cutter of described band datum level and pass baseline is set-point A1; Described measuring tool comprises the linear standards that has scale, fixation measuring pin and the movable pin of measuring, and the fixation measuring pin is positioned at an end of linear standards, the pin type down, the movable footmuff of measuring is loaded on the linear standards, the pin type up.

A kind of device processing roll that utilizes claim 1 is the method for pass in groups, comprises the steps:

1) the pass baseline that provides of drawing is to the size A of roll datum level, and it deducts the size A1 of pass baseline to the datum level of the molding cutter of band datum level, calculates the size A2 of roll datum level to the datum level of the molding cutter of band datum level;

2) horizontal direction traverse measurement plate makes the movable pin of measuring prop up the roll datum level, reads A2 on linear standards, and the fixing movable pin of measuring.

3) mobile lathe cutter saddle makes the datum level of the molding cutter of band datum level prop up the fixation measuring pin, has promptly guaranteed the size of roll datum level to the pass baseline: A1+A2=A

4) feed is processed pass.

5) molding cutter of the different datum levels of tape swapping more repeats above-mentioned steps, processes the different passes on the same roll.

Owing to adopted technique scheme, the invention has the beneficial effects as follows:

1. the roll use of pass processing unit (plant) in groups because employing is that the method for measuring is come controlling dimension A, improves its positioning accuracy, and measure error is 0.05, and line is processed as 1.0.

2. only need repeat roll pass processing method in groups, just can on same roll, process different passes, not need more roll change frame; do not need to shut down to pass; so not only save the expense of frequent replacing differential roller frame, promptly saved cost, also improved working (machining) efficiency simultaneously.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done a progressive explanation.

As shown in Figure 2, a kind of roll is the pass processing unit (plant) in groups, molding cutter 6 and a measuring tool that is fixedly installed on the measurement plate 10 of comprising the band datum level that is installed on the lathe, on the molding cutter 6 of band datum level a datum level is arranged, scale on the molding cutter 6 of band datum level is represented the distance of this datum level to the pass baseline, A1 represents with size, and it is engraved on a side of the molding cutter 6 of band datum level; Measuring tool comprises the linear standards 8 that has scale, fixation measuring pin 7 and the movable pin 9 of measuring, and fixation measuring pin 7 is positioned at an end of linear standards 8, the pin type down, the movable pin 9 of measuring is set on the linear standards 8, the pin type up.

Utilize this device breaker roll in groups the processing method of pass carry out as follows:

1) the pass baseline that provides according to drawing (center line shown in Fig. 2) is to the size A of roll datum level 11, it deducts the size A1 of pass baseline to the datum level of the molding cutter 6 of band datum level, calculates the size A2 of roll datum level 11 to the datum level of the molding cutter 6 of band datum level;

2) move horizontally measurement plate 10, make the movable pin 9 of measuring prop up roll datum level 11, on linear standards 8, read A2, and fixing movable measurement pin 9.

3) mobile lathe cutter saddle makes the datum level of the molding cutter 6 of band datum level prop up fixation measuring pin 7, has promptly guaranteed the size of roll datum level 11 to the pass baseline: A1+A2=A

4) feed is processed pass.

5) molding cutter 6 of the different datum levels of tape swapping more repeats above-mentioned steps, processes the different passes on the same roll.

As shown in Figure 2, repeat above-mentioned steps the pass in groups on the same roll is added man-hour, do not need roller frame 1, only needing more, the molding cutter 6 of the different datum levels of tape swapping gets final product.Use this kind devices and methods therefor, guaranteed the degree of accuracy and the homogeneity of size Control, can process any roll Pass separately, and can reach the requirement of pairing.Not only can improve the machining accuracy of pass in groups, also improve working (machining) efficiency, save processing cost.
