Description

A device for boring or reaming a hole using a lathe

technical field

The utility model relates to an accessory device of a lathe, in particular to a device for boring or reaming a hole by using a lathe.

Background technique

Reaming on a lathe, the general processing method is to install the workpiece on the chuck, and the turning tool on the tool holder. That is, the workpiece is rotated, and the turning tool is fed horizontally or vertically. If the center of the hole to be machined and the center of rotation of the workpiece are concentric, it is sufficient to clamp the workpiece directly on the chuck of the lathe. However, in the actual processing process, there is often a phenomenon that the two are not concentric, and the hole to be processed must meet other technical requirements (such as ensuring the center distance with other holes on the workpiece, etc.). In this case, a four-jaw chuck can be used to make the center of the hole to be processed coincide with the turning center of the lathe, and the processing can also be realized. But the shortcoming of this processing method is that each workpiece will be stopped for loading and unloading after processing, and each workpiece will be debugged before processing. For hole processing with center distance requirements, it is time-consuming and laborious, and the quality is not stable. Therefore, this processing method is only suitable for single-piece, small-batch production.

Contents of the invention

The purpose of this utility model is to provide a device for boring or reaming holes by using a lathe to solve the problem that the workpiece must be stopped for loading and unloading during the processing of the workpiece, so as to improve the efficiency and ensure the quality of the workpiece.

The technical scheme adopted by the utility model is: it is connected by the lathe spindle and the flange, and the flange is connected with the boring bar seat, and the boring bar seat is fixed on the boring bar seat through the boring bar pressing plate and the pressing plate bolt, A boring cutter is installed on the boring bar; a boring template that can move along the lathe track is installed in front corresponding to the boring bar; the boring template is connected with the boring frame through fixing bolts, and the boring frame is connected with the large carriage through a spacer. The large carriage is connected with the lathe track and can move on the lathe track.

The utility model is beneficial in that: because the utility model can realize the clamping of the workpiece without stopping the vehicle, and can realize the rapid and accurate positioning of the workpiece, it is beneficial to improve the work efficiency and ensure the product quality. At the same time, for holes with center distance requirements on the workpiece, several different template holes made on the boring template can be used to meet the requirements of workpiece clamping and processing.

Detailed ways:

As shown in Figure 1, it is a schematic diagram of the utility model, which is connected by the lathe spindle 21 with the flange 2, the flange 2 is connected with the boring bar seat 3, and the boring bar seat 3 is connected by the boring bar pressing plate 4 and the pressing plate bolt 41. The boring bar 5 is fixed on the boring bar seat 3, and the boring tool 6 is installed on the boring bar 5; the boring template 8 that can move along the lathe track 9 is installed in the front corresponding to the boring bar 5; the boring template 8 passes through the fixing bolt 81 Link to each other with boring mold frame 10, and boring mold frame 10 links to each other with large carriage 12 through spacer 11, and large carriage 12 links to each other with lathe track 9, and can move on lathe track 9 to form.

The boring template 8 described in the utility model is made with the template hole 82 of some different diameters. Different distances between each template hole 82 and the center of the boring template 8 can be used to process multiple holes with different center distances.

The diameter of template hole 82 described in the utility model is 15-20 millimeters.

The boring tool 6 described in the utility model adopts the tightening screw 61 to be locked on the boring bar 5 .

The working principle of the present utility model is: because the boring bar seat 3 is connected with the flange plate 2 and kept concentric with the flange plate 2 during installation, the boring bar 5 is connected with the boring bar seat 3 and ensures that the center of the boring bar 5 is aligned with the lathe spindle 21 The centers coincide, so as long as the distance between the boring tool 6 tool tip and the boring bar 5 center is adjusted, the size of the workpiece hole 71 of the workpiece 7 to be processed can be adjusted. When starting to process, adjust the boring tool 6 so that the boring tool 6 has a suitable machining allowance. At the same time, after positioning the workpiece 7, clamp the workpiece 7 with a special fixture, and then start the lathe, and the boring tool 6 will rotate. Driven by the large carriage 12, it moves evenly and slowly along the lathe track 9. After the processing is completed, the large carriage 12 withdraws in the opposite direction, unclamps the special fixture and unloads the workpiece 7, and the processing process is completed.

In the utility model, in order to ensure the continuity and processing quality of processing, 2-3 boring cutters 6 can be installed on the boring bar 5 to keep continuous processing during processing.
