Abstract
The utility model discloses a plunger bushing central hole grinding tool which comprises a tool bar (1) and a tool handle (2) used for being connected with a machine tool. Two grinding sleeves (3) coated and plated with diamond micro-powder grinding materials are arranged on the tool bar (1), a connecting part (4) is arranged between the two grinding sleeves (3), and the outer diameter of the connecting part (4) is smaller than the outer diameters of the grinding sleeves (3). The plunger bushing central hole grinding tool effectively solves the problems that a traditional grinding tool is adopted in an existing plunger bushing central hole grinding tool, the end at the spaced position of a plunger bushing is prone to grinding off, and the quality of products is influenced. The plunger bushing central hole grinding tool is simple and reasonable in structure, scientific in design and capable of facilitating industrial production.
Description
technical field:
The utility model relates to machining cutter, is specifically related to a kind of plunger bushing mesopore and whets a knife.
background technology:
?at present, mechanic factory workers is when processing precise plunger bushing mesopore, conventionally adopt traditional sharpening, due to the particularity of plunger bushing, the mesopore of plunger bushing is not continuous through hole, but the centre bore of two interruptions forms, in processing plunger bushing centre bore process, if adopt the centre bore of two interruptions of traditional sharpening processing plunger bushing, whet a knife and easily two terminations of being interrupted centre bore are ground in the course of work, thereby cause the defective of product quality.
summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of plunger bushing mesopore and whets a knife, and the utility model effectively solves existing plunger bushing mesopore and whets a knife and adopt traditional sharpening, easily termination, plunger bushing interval is ground away, thereby affects the problem of product quality; This cutter structure advantages of simple, design science, be convenient to industrialization and produce.
The utility model is achieved through the following technical solutions:
A kind of plunger bushing mesopore is whetted a knife, comprise knife bar (1), and the handle of a knife (2) for being connected with lathe, it is characterized in that: two grinding covers (3) that have painting to be coated with diadust abrasive material are set on described knife bar (1), between two grinding covers (3), be provided with connecting portion (4), connecting portion (4) outside dimension is less than grinding cover (3) outside dimension.
The further Technological improvement plan of the utility model is:
On described knife bar (1), be also provided with adjusting nut (5), grinding cover (3) is by adjusting nut (5) and adjustable connection of knife bar (1).
The utility model enters a more step Technological improvement plan:
Described diadust abrasive grain is 60 orders or is 80 orders or is 120 orders.
The utility model compared with prior art, has following obvious advantage:
One, the utility model is by two grinding covers are set on knife bar, and is provided with connecting portion between two grindings covers, there is no blade above connecting portion, and just with two central hole locations are corresponding.
Two, the utility model grinding cover, by adjusting nut and knife bar, can regulate for different plunger bushing sizes, has further improved the scope of application.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
As shown in Figure 1, the utility model comprises knife bar 1, and the handle of a knife 2 for being connected with lathe, two grinding covers 3 that have painting to be coated with diadust abrasive material are set on knife bar 1, between two grinding covers 3, be provided with connecting portion 4, connecting portion 4 outside dimensions are less than grinding and overlap 3 outside dimensions, are also provided with adjusting nut 5 on knife bar 1, grinding cover 3 is connected with knife bar 1 is adjustable by adjusting nut 5, and diadust abrasive grain is 60 orders or is 80 orders or is 120 orders.
In sum, the utility model can be realized goal of the invention.
