Description

Technical Field

[0001] The utility model relates to a boring tool for recycling waste blades, belonging to the technical field of boring tools. Background Art

[0002] The large hole processing of automobile engine connecting rods requires three steps: rough boring, chamfering, and fine boring. A variety of blades are consumed during the processing, resulting in high tool costs. Most existing manufacturers usually reduce feed parameters to improve tool durability and save tool costs, but this method will also reduce the processing efficiency of the equipment, resulting in increased personnel costs and low practicality. Now there is an urgent need for a boring tool that can recycle used blades to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a boring tool for recycling waste blades to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure and can fully utilize the first blade through the arrangement of a rough boring shaft and a chamfering shaft, thereby reducing the tool cost and having strong practicality.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a boring tool for recycling waste blades, comprising a boring tool seat, a connecting shaft, a fine boring shaft, a chamfering shaft, a rough boring shaft, an empty slot, a first blade, a tool holder and a second blade, the rear end of the boring tool seat is welded with a connecting shaft, the front end face of the boring tool seat is provided with a fine boring shaft, the front end of the fine boring shaft is provided with a chamfering shaft, the front end of the rough boring shaft is provided with a rough boring shaft, the rough boring shaft is provided with an empty slot inside, the empty slot is provided with a first blade, the outer side surface of the fine boring shaft is clamped with a tool holder, and the front end face of the tool holder is installed with a second blade.

[0005] Furthermore, a first positioning groove is provided inside the rough boring shaft, and a second positioning groove and a third positioning groove are provided inside the chamfering shaft, and the first positioning groove, the second positioning groove and the third positioning groove are connected to the empty groove.

[0006] Furthermore, the first blade is respectively engaged with the first positioning groove, the second positioning groove and the third positioning groove.

[0007] Furthermore, six groups of the first blades are provided with equal specifications, and the first blades are square in shape.

[0008] Furthermore, a positioning hole is formed through the surface of the first blade, and the first blade is fixedly connected to the rough boring shaft via the positioning hole and a locking bolt.

[0009] Furthermore, the second blade is in a rhombus shape, and the second blade is fixedly connected to the blade holder via a locking bolt.

[0010] The beneficial effects of the utility model are as follows: the utility model is a boring tool for recycling waste blades. Since the utility model adds a rough boring shaft, a chamfering shaft, a first positioning groove, a second positioning groove and a first blade, by using the first blade of the same specification in the rough boring and chamfering processes, and based on the premise that the cutting positions of the first blade used for rough boring and chamfering are different and thus the blade wear is different, the first blade is used after the tip of the rough boring tool is worn and then switched to the chamfering position to continue cutting with the blade, and the blade used for chamfering avoids the tip and the blade used for rough boring, thereby making full use of the blade edge and reducing the processing cost.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 4The utility model provides a technical solution: a boring tool for recycling waste blades, comprising a boring tool seat 1, a connecting shaft 2, a fine boring shaft 3, a chamfering shaft 4, a rough boring shaft 5, an empty slot 6, a first blade 11, a tool holder 14 and a second blade 15. The connecting shaft 2 is welded at the rear end of the boring tool seat 1, the fine boring shaft 3 is arranged on the front end face of the boring tool seat 1, the chamfering shaft 4 is arranged on the front end of the fine boring shaft 3, the rough boring shaft 5 is arranged on the front end of the rough boring shaft 5, an empty slot 6 is opened inside the rough boring shaft 5, the first blade 11 is arranged inside the empty slot 6, the tool holder 14 is clamped on the outer side surface of the fine boring shaft 3, and the second blade 15 is installed on the front end face of the tool holder 14. This design solves the problems of low utilization rate of tools and high production cost of the original boring tool.

[0019] As a first embodiment of the utility model: a first positioning groove 7 is provided inside the rough boring shaft 5, and the first positioning groove 7 can position and limit the first blade 11 installed inside the rough boring shaft 5, and a second positioning groove 8 and a third positioning groove 9 are provided inside the chamfering shaft 4, and the second positioning groove 8 and the third positioning groove 9 can position and limit the first blade 11 installed inside the chamfering shaft 4, and the first positioning groove 7, the second positioning groove 8 and the third positioning groove 9 are connected with the empty groove 6, and the first positioning groove 7, the second positioning groove 8 and the third positioning groove 9 can make full use of the blade, thereby reducing the tool cost, and the first blade 11 is respectively connected with the first positioning groove 8 and the third positioning groove 9. The positioning groove 7, the second positioning groove 8 and the third positioning groove 9 are engaged with each other. Six groups of first blades 11 and other specifications are provided. The first blade 11 is square in shape. The square blade can perform rough boring and chamfering better. A positioning hole 12 is opened through the surface of the first blade 11. The first blade 11 is fixedly connected to the rough boring shaft 5 through the positioning hole 12 and the locking bolt 13. The positioning hole 12 and the locking bolt 13 can fix the position of the first blade 11. The second blade 15 is rhombus in shape. The second blade 15 is fixedly connected to the tool holder 14 through the locking bolt 13. The locking bolt 13 can fix the second blade 15 and the tool holder 14.

[0020] As the second embodiment of the utility model: the user first installs the first blade 11 in the first positioning groove 7 inside the rough boring shaft 5, and fixes it by the locking bolt 13, and uses its tool tip for rough boring cutting. After the first blade 11 is processed to the tool durability and the tool tip is worn, the first blade 11 is installed in the second positioning groove 8 located on the chamfering shaft 4 to perform chamfering. Similarly, according to the processing situation, it can be installed in the third positioning groove 9 to perform chamfering on the other side. Since the amount of metal removed in rough boring is twice that of chamfering, and there are two tool positions for chamfering on the front and back sides, the number of first blades 11 used is exactly twice that of rough boring. Therefore, the worn blades in rough boring are just consumed at the chamfering station, so that the first blade 11 is fully utilized and the production cost is reduced. The tool holder 14 is used for fine boring of large holes. The blade for fine boring is a diamond blade whose blunt-angle tip is not fully utilized after the balancing shaft is turned.
