Problems solved by technology

Since there are many annular sealing grooves on the part, see image 3 , 4 As shown in , such parts are generally processed by CNC machine tool programming, but for old-fashioned boring machines such as digital display, it cannot be processed without adopting methods. There is no internal cooling system, the cutting speed is low, and the processing with end mills is also very slow

Embodiment 1

[0029] Such as figure 1 , 2 Among them, a device for machining annular sealing grooves using a common boring machine, including a boring bar 2, a tool 3 is eccentrically fixed on the boring bar 2, the axis of the tool 3 is parallel to the axis of the boring bar 2, and the eccentric distance of the tool 3 is in line with the end surface of the part 6 The radii of the upper annular sealing grooves 5 are the same. With this structure, the annular sealing groove 5 around the through hole on the end surface of the part 6 can be processed through the rotation of the machine tool spindle 1 and the feed of the Z axis. The cutter 3 in this example is a white steel cutter, and the square size is 7mm×7mm.

[0030] The preferred solution is as figure 2 Among them, the tool 3 is fixedly connected with the secondary transfer boring bar 7, and the secondary transfer boring bar 7 passes through the fixing hole of the boring bar 2. The fixing hole is usually a square through hole, and a s...

Embodiment 2

[0035] On the basis of Embodiment 1, a processing method of a device for processing an annular sealing groove using a common boring machine comprises the following steps:

[0036] 1. Adjust the rotation center of the boring bar 2 to align with the axis of the through hole in the annular sealing groove 5;

[0037] 2. Locate the position of the cutter 3 according to the radius of the annular sealing groove 5;

[0038] 3. Start the machine tool spindle 1 to start processing, and the machine tool spindle 1 feeds;

[0039] Through the above steps, after adjusting the cutting radius, through the rotation of the main shaft and the feed of the main shaft of the machine tool along the Z axis, the ordinary boring machine can be used to process the annular sealing groove that meets the requirements of the drawing.

[0040] In a preferred solution, the length between the clamping position of the tool 3 and the cutting edge is minimized while ensuring the cutting depth.

[0041] The spin...

Abstract

The invention provides a device and method for processing an annular sealing groove by using an ordinary boring machine, which includes a boring bar on which a tool is eccentrically fixed and fixed, the axis of the tool is parallel to the axis of the boring bar, and the eccentric distance of the tool is in line with the annular sealing groove on the end surface of the part. of the same radius. The processing method includes the following steps: 1. Adjusting and aligning the rotation center of the boring bar with the axis of the through hole in the annular sealing groove; 2. Positioning the tool according to the radius of the annular sealing groove; Spindle feed; through the above steps, the annular sealing groove can be processed by ordinary boring machine. By adopting the method of eccentrically fixing the tool, the annular sealing groove around the through hole can be processed conveniently and quickly. It is suitable for machining annular sealing grooves with ordinary boring machines, that is, non-NC boring machines. This kind of device can be used to complete the rough and fine machining of annular sealing grooves on digital display non-NC boring machines, and even ordinary boring machines.

Description

technical field [0001] The invention relates to the field of machining, in particular to a device and method for machining an annular sealing groove by using a common boring machine. Background technique [0002] In the field of metallurgical equipment manufacturing, the requirements for welding, processing and assembly of various parts are relatively high. In particular, most metallurgical equipment needs to be cooled by water, so the sealing performance of parts is required to be high. Since there are many annular sealing grooves on the part, see image 3 , 4 As shown in , such parts are generally processed by CNC machine tool programming, but for old-fashioned boring machines such as digital display, it cannot be processed without adopting methods. There is no internal cooling system, the cutting speed is low, and the processing with end mills is also very slow. Ordinary reformed CNC boring machine processing, the spindle speed of the machine tool is usually 400 ~ 600r...
