Abstract
The utility model provides a tooth axle type part gerar grinding clamping frock, its characterized in that: the clamping device is provided with a hollow sleeve, a plurality of groups of screw holes are uniformly distributed on the circumference of the wall of the sleeve, a set screw is screwed into the screw holes and extends into the sleeve, and the set screw abuts against the outer surface of a gear shaft part inserted into the sleeve to clamp the gear shaft part. The utility model discloses be particularly useful for the not good condition of gear shaft class part centre bore. When the existing gear shafts are repaired, the center holes in two ends of a plurality of gear shafts are found to be poor, and by the method, clamping can be directly carried out without the condition of the center holes, then the meter is calibrated and aligned, the clamping efficiency can be improved, and the production progress is accelerated.
Description
Technical Field
The utility model relates to a wind-powered electricity generation gear box maintenance frock especially relates to a processing field is reprocessed to wind-powered electricity generation master gear box pinion shaft class part.
Background
At present, the gear grinding for repairing gear shaft parts is completed by clamping a workpiece shaft neck by a three-jaw chuck and propping a center hole at the upper end and the lower end of a machine tool by a center with a center hole.
The prior art needs to ensure that the processing precision of the central hole meets the requirements (the size and the roughness are qualified); and the workpiece is clamped by the three-jaw chuck to be connected and fixed with the workbench.
When present tooth axle class was reprocessed, it was relatively poor to discover a lot of tooth axle both ends centre bore situations, and like this, the clamping is got up and is guaranteed the precision and just very troublesome, needs a large amount of very troublesome adjustments, and production efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a tooth axle type part grinds tooth clamping frock, the shortcoming of prior art is solved to its purpose, provides a clamping convenient quick for production efficiency's tooth axle type part grinds tooth clamping frock.
The utility model provides a technical scheme that its technical problem adopted is:
gear grinding clamping tool for gear shaft parts is characterized in that:
the clamping device is provided with a hollow sleeve, a plurality of groups of screw holes are uniformly distributed on the circumference of the wall of the sleeve, a set screw is screwed into the screw holes and extends into the sleeve, and the set screw abuts against the outer surface of a gear shaft part inserted into the sleeve to clamp the gear shaft part.
Each group of screw holes is provided with two or more screw holes arranged from top to bottom.
The bottom of the sleeve is provided with an annular convex wall, a plurality of through holes are uniformly distributed on the circumference of the annular convex wall, and the connecting bolt penetrates through the through holes and then is screwed into the screw hole of the workbench to fixedly connect the sleeve on the workbench.
The through hole arranged on the annular convex wall at the bottom of the sleeve is a strip-shaped adjusting through groove.
And a copper sheet is placed at the end part of the set screw, which is contacted with the gear shaft type part.
The utility model discloses an useful part lies in:
the utility model discloses be particularly useful for the not good condition of gear shaft class part centre bore. When the existing gear shafts are repaired, the center holes in two ends of a plurality of gear shafts are found to be poor, and by the method, clamping can be directly carried out without the condition of the center holes, then the meter is calibrated and aligned, the clamping efficiency can be improved, and the production progress is accelerated.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a cross-section of the present invention;
FIG. 2 is a schematic top view of the present invention;
fig. 3 is a combination view of the present invention and the gear shaft parts.
Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.
As shown in fig. 1 and 2:
the utility model discloses have cavity sleeve 2, the protruding wall 21 of annular of cavity sleeve 2 bottom is equipped with the bar adjustment that 4 circumference equipartitions leads to groove 22.
Four groups of screw holes are uniformly distributed on the wall of the sleeve 2, each group of screw holes comprises an upper screw hole and a lower screw hole, a set screw 3 is screwed into each screw hole, and the set screws 3 go deep into the sleeve 2 for 8 set screws 3.
As shown in fig. 3:
the connecting bolt 4 passes through the strip-shaped adjusting through groove 22 and then is screwed into a screw hole of the workbench 5, and the sleeve 2 is fixedly connected on the workbench 5 through the connecting bolt 4. The strip-shaped adjustment through slot 22 allows the connecting bolt 4 to be movably adjusted therein so that the sleeve 2 is more accurately fixed on the worktable 5.
The hoisting gear shaft part 1 is inserted and arranged in the sleeve 2, a copper sheet is arranged at the contact position of the set screws 3 and the hoisting gear shaft part 1 so as to prevent a workpiece from being damaged, the set screws 3 (8 in total) are screwed down to push against the outer surface of the gear shaft part 1, the workpiece gear shaft part 1 is clamped, the twist-in depth of different set screws 3 is adjusted at the same time, the gear shaft part 1 is moved, and simultaneously, meter calibration and alignment are carried out until the gear shaft part 1 is in a proper clamping state.
That is, 4 groups of circumference equipartition, every two of group arrange from top to bottom, totally 8 holding screw 3 can separate the adjustment, no matter how the centre bore situation of tooth axle class part 1, these 8 holding screw 3 can all adjust tooth axle class part 1 to suitable clamping state.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
