Abstract
The utility model provides a mandrel for machining a cylinder liner outer surface. The mandrel is characterized by comprising a mandrel main body, wherein the mandrel main body is a solid step shaft provided with central holes at both ends, the mandrel main body runs through the cylinder liner, a first step surface on a large end of the mandrel main body is placed against the outer wall of the rear end of the cylinder liner, and a second step surface on a small end of the mandrel main body is placed against the inner wall of the front end of the cylinder liner. With the adoption of the mandrel, the cylinder liner machining process is simplified, and the manpower and material resources are saved.
Description
Technical field:
The utility model relates to a kind of plug that is used for the processing cylinder sleeve outer surface.
Background technology:
Cylinder sleeve is the parts that are used in the electric tool, and is as shown in Figure 1, and its outer surface has and much is used for being connected with other parts of electric tool or spacing stopper slot and step surface, and this just needs to process on the lathe; Because cylinder sleeve is the structure of hollow, mechanical strength is not high, is therefore adding man-hour; For preventing the cylinder sleeve fracture, every processing one place all need cool off; Reprocess another place, the operation trouble wastes time and energy.
The utility model content:
The main purpose of the utility model is, overcomes existing technological deficiency, provides a kind of operation simple, the plug that is used for the processing cylinder sleeve outer surface that uses manpower and material resources sparingly.
The technical scheme that the utility model provides is: the utility model provides a kind of plug that is used for the processing cylinder sleeve outer surface; It is characterized in that: it comprises the plug body; Said plug body is the solid step axle that two ends have centre bore; Said plug body passes cylinder sleeve, and the first step face on the big end of plug body and the outer wall of cylinder sleeve rear end offset, and the second step face on the small end of plug body and the inwall of cylinder sleeve front end offset.
Adopt said structure, the utlity model has following advantage:
The utility model adopts plug to pass cylinder sleeve, is connected with cylinder sleeve and fixes, when the processing cylinder sleeve surface; The two ends that anchor clamps are clamped plug through centre bore get final product the processing of outer city to liner backs, and the mechanical strength of plug is higher, therefore when the processing cylinder sleeve outer surface; Can not need disassemble, cool off, the time processing moulding; Operation is simple, uses manpower and material resources sparingly.
As improvement, also be provided with the thread spindle that is used for cooperating the clamping cylinder sleeve on the small end of said plug body with nut.Adopt nut and thread spindle to cooperate, after the plug body passed cylinder sleeve, fastening nut was fixed plug body and cylinder sleeve, prevents to become flexible.
Description of drawings:
Accompanying drawing 1 is the structural representation of cylinder sleeve;
Accompanying drawing 2 is used for the structural representation of the plug of processing cylinder sleeve outer surface for the utility model;
Accompanying drawing 3 is used for the plug of processing cylinder sleeve outer surface and the assembly structure sketch map of cylinder sleeve for the utility model;
As shown in the figure: 1, plug body, 1.1, the first step face, 1.2, the second step face, 1.3, thread spindle, 2, cylinder sleeve, 3, nut, 4, pad.
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated:
Like Fig. 2, shown in Figure 3: the utility model provides a kind of plug that is used for the processing cylinder sleeve outer surface; It comprises plug body 1; Said plug body 1 is the solid step axle that two ends have centre bore; Said plug body 1 passes cylinder sleeve 2, and the first step face 1.1 on the big end of plug body 1 offsets with the outer wall of cylinder sleeve 2 rear ends, and the second step face 1.2 on the small end of plug body 1 offsets with the inwall of cylinder sleeve 2 front ends.The big end of plug body 1 is meant the end that the diameter of plug body 1 is bigger, and the less end of the diameter of plug body 1 is a small end.
As improvement, also be provided with the thread spindle 1.3 that is used for cooperating clamping cylinder sleeve 2 on the small end of said plug body 1 with nut 3.In the present embodiment, nut 3 is spirally connected through pad 4 and thread spindle 1.3, and during work, fastening nut 3 compresses plug body 1 and cylinder sleeve 2, prevents to become flexible.
