During operation, the fixed plate is arranged on a tool rest of the numerical control lathe and fixed by bolts, the gear shaft to be polished is arranged on a main shaft chuck of the numerical control lathe, the polishing blade is tightly attached to the tool withdrawal groove, the tool withdrawal groove can be effectively polished, the efficiency is high, the polishing precision is good, and the flatness is consistent.
Description
Technical Field
The utility model belongs to the technical field of super-finishing machine and specifically relates to a special frock of gear shaft escape groove polishing is related to.
Background
The gear shaft is a common shaft-shaped part in the mechanical industry, and in the machining process, in order to facilitate the withdrawal of a cutter, a tool withdrawal empty groove, called a tool withdrawal groove, is reserved at the tail end of a surface to be machined. After the relief groove is machined, burrs are formed on the surface of the relief groove, so that the surface of the relief groove needs to be polished to be bright and flat.
Currently, the tool withdrawal groove is polished by a manual method, such as an operator polishing the tool withdrawal groove by using sand paper or a hand-held pneumatic polisher. Firstly, the polishing mode has low efficiency and high labor cost; secondly, the precision and the flatness after polishing cannot be ensured, and the polishing effect is poor; thirdly, potential safety hazards exist.
Disclosure of Invention
An object of the utility model is to provide a special frock of gear shaft escape groove polishing to solve defects such as inefficiency, poor precision, with high costs that current manual polishing method exists.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
the special tool for polishing the tool withdrawal groove of the gear shaft comprises a fixed cylinder and a fixed plate which axially and horizontally extends along the outer side surface of the fixed cylinder, wherein a plurality of internal thread fixing holes are formed in the side wall of the fixed cylinder, which is 90 degrees away from the fixed plate, along the axial direction at intervals, and fixing bolts are screwed in the internal thread fixing holes; the rotating shaft of the grinding machine movably inserted in the fixed cylinder extends forwards, and the end part of the rotating shaft is provided with a polishing blade.
During operation, the fixed plate is arranged on a tool rest of the numerical control lathe and fixed by bolts, the gear shaft to be polished is arranged on a main shaft chuck of the numerical control lathe, the polishing blade is tightly attached to the tool withdrawal groove, the tool withdrawal groove can be effectively polished, the efficiency is high, the polishing precision is good, and the flatness is consistent.
The grinding machine is a linear pneumatic grinding machine.
The utility model has the advantages of: adopt abrasive paper or handheld pneumatic polisher to gear shaft tool withdrawal groove polish with manual and compare, adopt the special frock installation of this application to polish the operation on numerical control lathe, can improve the polishing efficiency in gear shaft tool withdrawal groove, can guarantee moreover that polishing effect is unanimous, and the precision is high, and the roughness is high, and the security can be ensured.

Fig. 2 is a usage state diagram of the present invention.
Detailed Description
The present invention is described in more detail below with reference to the attached drawings so as to facilitate understanding for those skilled in the art.
As shown in fig. 1, the special tool for polishing the tool withdrawal groove of the gear shaft of the present invention comprises a fixed cylinder 1 and a fixed plate 2 extending horizontally along the outer side surface of the fixed cylinder 1, and in order to facilitate installation and ensure firm fixation, the fixed plate 2 can extend backward to a certain length; at least two internal thread fixing holes are formed in the side wall of the fixing barrel 1 at a 90-degree position with the fixing plate 2 at intervals along the axial direction, and a fixing bolt 3 is screwed in each internal thread fixing hole; the rotating shaft of the grinding machine 4 movably inserted in the fixed cylinder 1 extends forwards, and the end part of the rotating shaft is provided with a polishing blade 5.
To reduce the production cost, the grinding machine 4 of the present application may be a linear pneumatic grinding machine, such as an S80 pneumatic grinding wheel manufactured by shanghai xinma pneumatic tool factory or Qingdao Qing-En-Dynasty tool Co.
During assembly, the polishing blade 5 is firstly installed at the end part of a rotating shaft of the grinding machine 4 (S80 type air grinding wheel), a cylindrical handle of the grinding machine 4 (S80 type air grinding wheel) is inserted into the fixed cylinder 1, and the cylindrical handle is extruded and fixed by using at least two fixing bolts 3.
During operation, fix fixed plate 2 on numerically controlled lathe saddle 6 (through four fastening bolt 7), the gear shaft 8 of treating the polishing is adorned on the main shaft chuck of digit control machine tool, adjusts well position between them, can carry out the polishing operation according to the procedure of setting for.
In practical use, the type of the polishing blade (such as a cloth wheel grinding wheel suitable for polishing) can be selected according to the size and the roughness requirement of the polished tool withdrawal groove, and the larger the relative speed is, the lower the roughness of the polished tool withdrawal groove is, because the rotating directions of the gear shaft 7 and the air grinding wheel are opposite.
Claims (2)
