Technical Field

[0001] This utility model belongs to the field of boring machine technology, and in particular relates to a boring machine. Background Technology

[0002] A boring machine is a specialized device for processing deep holes in hydraulic cylinders, air cylinders, and other hydraulic cylinders. It can also process spindle holes, blind holes, and stepped holes in machine tools. The machine tool can not only perform various drilling and boring operations, but also roll forming, making it an indispensable piece of equipment in metal processing.

[0003] When using a traditional boring machine, the friction between the cutting tool and the workpiece generates high heat, causing the cutting tool to overheat and accelerate its wear. On the other hand, the chips generated during boring fall onto the inner wall of the workpiece, and when the cutting tool comes into contact with the chips, it affects the machining accuracy of the workpiece. Utility Model Content

[0004] This utility model provides a boring machine, which aims to solve the problems of excessively high blade temperature during the operation of current boring machines and the impact of boring debris on machining accuracy.

[0006] Preferably, the workbench has limit grooves on both the left and right sides of its surface, the limit block is slidably embedded in the limit groove, the limit block has a slot hole at its center and a pin is installed thereon, and the surface of the limit groove has slots at equal intervals that are adapted to the pin.

[0007] Preferably, the bottom of the pin is threaded, and the slot of the limiting groove is provided with a threaded groove that matches the thread on the surface of the pin.

[0008] Preferably, the bottom of the limiting block is symmetrically provided with cylindrical grooves, and a rotating roller is installed in the groove.

[0009] Preferably, a brush plate is installed at the bottom of the connecting plate, the brush plate being in line with the width of the filter screen and in contact with its surface.

[0010] Preferably, the liquid outlet is inclined and a mesh sleeve is fitted over the outside of the liquid outlet.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] The device features a liquid tank where cutting fluid is driven by a pump through a delivery pipe into a hollow rotating shaft. This fluid is then sprayed onto the cutting tool from the shaft's surface, cooling the tool and removing debris generated during boring. This prevents debris from affecting the boring accuracy by remaining on the workpiece surface. The cutting fluid is filtered through a screen and returned to the liquid tank, thus achieving fluid recycling. A brush plate is also included; as the platform slides horizontally, it removes debris falling onto the filter screen, thus assisting in its cleaning. Attached Figure Description

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a boring machine, such as Figure 1-5 As shown, the system includes a workbench 1, a support frame 2 mounted on top of the workbench 1, a rotating shaft 3 rotatably mounted on the inner side of the support frame 2, a motor 4 mounted on the upper end of the workbench 1, a set of meshing gears 5 mounted on the output shaft of the motor 4 and the surface of the rotating shaft 3, a liquid tank 6 mounted on the lower left of the workbench 1, a drive pump 7 mounted on the bottom of the liquid tank 6, an infusion pipe 8 connected to the output port of the drive pump 7, the other end of the infusion pipe 8 connected to the shaft end of the rotating shaft 3, the rotating shaft 3 having a hollow internal structure and an outlet 9 on its surface, the infusion pipe 8 being connected to the rotating shaft 3 via a sealed bearing, a groove being formed on the surface of the workbench 1, and a filter screen 10 being installed in the groove, a return channel 11 being formed below the filter screen 10 corresponding to the surface of the workbench 1, the return channel 11 being connected to the upper right corner of the liquid tank 6, and two sets of limiting blocks 12 symmetrically mounted on the left and right sides of the surface of the workbench 1. A connecting plate 13 is installed between the two parts, and a placement platform 14 is installed on the upper end of the connecting plate 13. When using this device, the cutting tool can be installed on the right end of the rotating shaft 3, and then the motor 4 is started. The motor 4 drives the rotating shaft 3 to rotate through a set of gears 5. The workpiece is then fixed on the placement platform 14 for boring. When the cutting tool is hot due to prolonged boring, the drive pump 7 in the liquid tank 6 can be started. The drive pump 7 inputs the cutting fluid into the interior of the rotating shaft 3 through the liquid inlet 8 and sprays it outward through the liquid outlet 9 on the surface of the rotating shaft 3. The sprayed cutting fluid will fall onto the surface of the cutting tool and the workpiece to cool the cutting tool. At the same time, it can wash away the chips generated by cutting to prevent the chips from being on the surface of the workpiece and affecting the boring accuracy. After the cutting fluid is sprayed out, it falls onto the surface of the worktable 1 and is filtered through the filter screen 10 before flowing back into the liquid tank 6 through the return tank 11, thus realizing the recycling of the cutting fluid.

[0022] Limiting grooves 15 are provided on both the left and right sides of the surface of the worktable 1. Limiting blocks 12 are slidably embedded in the limiting grooves 15. A slot is provided in the center of the limiting block 12 and a pin 16 is installed. The surface of the limiting groove 15 is provided with slots that are compatible with the pin 16 at equal intervals. By providing the limiting grooves 15, the limiting blocks 12 are slidably installed in the limiting grooves 15 and limited by the pin 16. The pin 16 can be pulled out and the placement table 14 can be pushed horizontally to adjust the position of the boring hole.

[0023] The bottom of the pin 16 is threaded, and the slot of the limiting groove 15 is provided with a threaded groove that matches the thread on the surface of the pin 16. By providing a thread at the bottom of the pin 16, the connection between it and the limiting groove 15 can be made more stable, and the placement table 14 can be prevented from shaking during boring.

[0024] The bottom of the limiting block 12 is symmetrically provided with columnar grooves, and a rotating roller 17 is installed in the grooves. By installing the rotating roller 17 at the bottom of the limiting block 12, the rotating roller 17 can convert the sliding friction between the limiting block 12 and the limiting groove 15 into rolling friction, which can make the placement platform 14 slide more smoothly and effortlessly.

[0025] A brush plate 18 is installed at the bottom of the connecting plate 13. The width of the brush plate 18 is the same as that of the filter screen 10 and it is in contact with its surface. By setting the brush plate 18, when the platform 14 slides horizontally, the brush plate 18 can brush away the debris that falls on the filter screen 10, thereby achieving auxiliary cleaning of the filter screen 10.

[0026] The outlet 9 is covered with a mesh sleeve. By tilting the outlet 9, it can be aligned with the position of the blade for spraying liquid. Covering the outlet 9 with a mesh sleeve can prevent debris from clogging the outlet 9.
