Description

Technical Field

[0001] The utility model relates to the technical field of portable boring machines, in particular to a drilling machine for boring. Background Art

[0002] A boring machine is a device specifically for machining deep-hole workpieces such as oil cylinders, cylinders, and hydraulic cylinders, and can also be used for machining the main shaft holes, blind holes, and stepped holes of machine tools. Currently, when using a portable boring machine, it needs to be installed and fixed first. When installing the boring bar, a dial indicator is required for centering, and then the positioning part is welded at the installation position, and the boring bar passes through the positioning part and extends into the machining position. The purpose of this process is to ensure the centering of the boring bar, so that the portable boring machine can travel stably during use. However, every time the portable boring machine is used, it is necessary to center and then weld the positioning part first, and subsequent removal is also required, which will affect the efficiency of boring machining and increase the operation complexity for workers during boring.

A fixed sleeve is provided on the boring bar. The positioning part includes a positioning ring adapted to the installation position. A plurality of positioning holes adapted to the installation position are provided in the positioning ring. Not less than one stress inclined rod is fixedly connected to the positioning ring and is arranged annularly and evenly. One end of the stress inclined rod is fixedly connected with an annular insertion rod. An annular insertion slot adapted to the annular insertion rod is provided in the fixed sleeve. The annular insertion rod is detachably connected in the annular insertion slot.

[0007] As an improvement, a through hole adapted to the boring bar is provided in the annular insertion rod, and the inner diameter of the through hole is larger than the diameter of the boring bar.

[0008] As an improvement, a hole position is provided on the annular insertion rod. Threaded holes adapted to the hole position are provided on both sides of the annular insertion slot in the fixed sleeve. The fixed sleeve is provided with installation surfaces arranged oppositely and adapted to the threaded holes and bolts.

[0011] As an improvement, reinforcing steel bars are embedded in the stress diagonal bars.

[0012] (III) Beneficial effects

[0013] The advantages of the present utility model compared with the prior art are as follows: When using the boring machine main body, it is necessary to first center the boring bar so that it extends into the machining position and position and fix the position of the boring bar. When positioning and fixing the boring bar, the boring bar is located at the center of the positioning ring. Place the positioning ring at a suitable position on the installation position and fix the positioning ring at the installation position using the positioning holes. At this time, the boring bar is located at the center of the positioning ring and there is no need for re-centering. When separating the positioning member from the boring machine main body, it is only necessary to remove the bolts on the installation surface, which is convenient for workers to use.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1

[0021] As Figure 1 , Figure 2And Figure 3 As shown, a drilling rig for boring holes includes a boring machine main body 1. The boring machine main body 1 includes a boring bar 2, and a boring tool 3 is provided on the boring bar 2. It also includes a positioning member 5. A fixing sleeve 4 is provided on the boring bar 2. The positioning member 5 includes a positioning ring 6 that fits the installation position. A number of positioning holes 11 that fit the installation position are provided inside the positioning ring 6. Not less than one stress inclined bar 7 is fixedly connected to the positioning ring 6 and is arranged evenly in a ring shape.

[0022] With the above structure, it is convenient to center and fixedly install the boring bar 2. The specific structure is as follows:

[0023] As Figure 1 、 Figure 2 、 Figure 3 And Figure 4 As shown, one end of the stress inclined bar 7 is fixedly connected with an annular insertion rod 8. A through hole that fits the boring bar 2 is provided inside the annular insertion rod 8. The inner diameter of the through hole is larger than the diameter of the boring bar 2. An annular slot 9 that fits the annular insertion rod 8 is provided inside the fixing sleeve 4. The annular insertion rod 8 is detachably connected inside the annular slot 9. A hole position is provided on the annular insertion rod 8. Threaded holes that fit the hole position are provided on both sides of the annular slot 9 inside the fixing sleeve 4. Mounting surfaces 10 that are arranged oppositely and fit the threaded holes and bolts are provided on the fixing sleeve 4. The positioning holes 11 are fixedly installed at the installation position through expansion bolts. Washers that fit the bolts are adhered to the periphery of the threaded holes on both mounting surfaces 10, which can improve the stability when the bolts are tightened in the threaded holes.

[0024] With the above structure, the positioning member 5 and the boring machine main body 1 can be disassembled and assembled.

[0025] Embodiment 2

[0026] As Figure 3 And Figure 4 As shown, reinforcing bars are embedded in the stress inclined bars 7.

[0027] With the above structure, the stability of the stress inclined bars 7 can be improved, thereby improving the smoothness when the boring bar 2 travels.

[0028] When the present utility model is specifically implemented, before boring with the boring machine main body, it is necessary to first center the boring bar, make it extend into the boring machining position, and position and fix it. During installation, extend the boring bar into the machining position, and at the same time make the positioning ring fit with the surface of the installation position. After fitting, the boring bar is in the centering position. Then drill a hole in the installation position through the positioning hole. After drilling, use bolts to fix the positioning ring at the installation position. Then the boring machine main body can be used. During the use of the boring bar, it will travel at the center of the positioning ring, and the stress inclined bar can improve the traveling stability. Since the boring bar is at the center position of the positioning ring, only the positioning ring needs to be fixedly installed each time the boring machine main body is installed. When it is necessary to disassemble the positioning part, remove the bolts on the installation surface, and then the annular insertion rod can be taken out from the annular slot. When it is necessary to install the positioning part, pass the annular insertion rod through the boring bar and insert it into the annular slot, and then use bolts to thread-connect the annular insertion rod and the fixing sleeve.
