Abstract

The utility model relates to a back face die processing device for a small shell. The back face die processing device comprises a circular disk and a tip, wherein a male spigot which is adaptive to a female spigot in the shell is formed in the front face of the circular disk; the front end (one end of which the diameter is larger) of the tip is connected to the back face of the circular disk; the tip is coaxial with the circular shaft; and the circular disk is further provided with a plurality of bolt holes. The tip is formed on the back face die processing device for the small shell, and has high coaxiality and high rigidity, so that circular run-out of a workpiece is controlled accurately by using the inherent characteristics of the tip, and the reliability and processing coaxiality of subsequent processing are ensured. Meanwhile, compared with a tool used in the prior art, the device has the advantages of simple structure, convenience in installing, saving in production time cost, and effective increase in the production efficiency.

Description

Little casing reverse side mould processing unit (plant)
Technical field
The utility model relates to a kind of little casing reverse side mould processing unit (plant).
Background technology
The process for machining of casing is generally that blank is fixed on lathe, and front end face is processed, and then anti-head clamps processing iron core shelves, other end and seam take the front end face seam as benchmark.
Existing clamping tool, during work, frock being connect dish by male half coupling and main shaft locates and uses 6 holes to be fixed on turntable of machine tool, after the recessed seam of casing front end face is enclosed within on male half coupling, by bolt with casing supporting hole, casing and frock are fixed together closely at last.
Exist location and installation error, workpiece easily to produce circle during due to each installation mold and beat, must re-start with casing positioning spigot place reliability and the concentricity that the guarantee following process is processed in turning to frock.And all to frock could be fixed on turntable of machine tool by holding screw before each the use.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of defects that solved is provided, and simple in structure, guaranteed the little casing reverse side mould processing unit (plant) of reliability and the concentricity of following process.
Little casing reverse side mould processing unit (plant) described in the utility model, comprise disk, the front of disk be provided with casing on the male half coupling that adapts of recessed seam, also comprise top, top front end (end that diameter is larger) is connected to the reverse side of disk, top coaxial with disk, also be provided with a plurality of bolts hole on disk.
Described disk is provided with 3 bolts hole, and 3 bolts hole are distributed on the outside of male half coupling.
Described top front end is welded on the reverse side of disk.
The beneficial effect that the utility model has is: little casing reverse side mould processing unit (plant) has been set up top, and top axiality is high, good rigidly, and the circle that utilizes top intrinsic characteristic accurately to control workpiece is beated, and guarantees reliability and the processing concentricity of following process.Compare simultaneously the frock that prior art is used, this apparatus structure is simple, and it is convenient to install, and has saved the production time cost, has effectively improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In figure: 1, disk; 2, male half coupling; 3, top; 4, bolt hole.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 1 ~ 2, the front of disk 1 be provided with casing on the male half coupling 2 that adapts of recessed seam, also comprise top 3, top 3 front end is welded on the reverse side of disk 1, top 3 is coaxial with disk 1, and disk 1 is provided with the outside that 4,3 bolts hole 4 of 3 bolts hole are distributed on male half coupling 2.
Processing and use procedure are:
Be placed in then firm welding of disk 1 center with top 3, be inserted in the machine tool chief axis axis hole and strain with pull bar.Then disk 1 is carried out turning processing, car goes out the male half coupling 2 that matches with recessed seam on the casing that will process.
Top 3 ends and machine tool chief axis are fixed, and the recessed seam of the manufactured front end face of casing and supporting the buckling well of male half coupling 2 on disk 1 are fixed on casing to be processed on disk 1 by bolt hole 4 use bolts, can carry out the processing of casing reverse side subsequently.
