The utility model belongs to the technical field of the tool grinder.
Background
The tool grinder is necessary auxiliary equipment for metal cutting processing and is used for sharpening various metal cutting tools, and the tool grinder is specially used for a grinder for sharpening the tools. Currently, grinding wheels used for sharpening are directly mounted on a main shaft, and therefore, the matching requirement of the grinding wheel and the main shaft is high.
Disclosure of Invention
The utility model aims at providing a fixed mode modified tool grinder of emery wheel, it improves tool grinder to emery wheel adaptation ability.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides a tool grinder of emery wheel fixed mode improvement, including the motor, the main shaft of being connected with the output shaft transmission of motor, the tip fixedly connected with spindle nose of main shaft, the outer tip of spindle nose is provided with the pyramis, be provided with the emery wheel fixing base of taper hole, the taper hole forms the conical surface cooperation with the pyramis, through twisting the bolt of closing in the center of pyramis with emery wheel fixing base and pyramis lock solid together, be equipped with emery wheel installation boss on the emery wheel fixing base, the emery wheel cover is established on emery wheel installation boss, the week of catch is along covering the lid on the emery wheel, lock solid together catch and emery wheel fixing base through the screw, and catch and emery wheel fixing base closely.
On the basis of the above scheme and as a preferable scheme of the scheme: the spindle head is connected with the spindle through reverse threads, and the spindle is further connected with a locking ring which can be tightly propped against the end part of the spindle head through threads.
Compared with the prior art, the utility model outstanding and profitable technological effect is:
the utility model discloses an instrument grinding machine that emery wheel fixed mode improved has adopted spindle nose, catch, emery wheel fixing base, locking ring isotructure, and when concrete application, the emery wheel passes through emery wheel fixing base and locking ring and is installed, and emery wheel fixing base passes through spindle nose and catch and is installed. Because the grinding wheel fixing seat is a part which is easy to process and has relatively low processing cost, the grinding wheel fixing seat with different specifications is matched with the grinding wheel, so that the grinding wheel matching capability of the tool grinding machine can be improved.

Detailed Description
In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.
In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.
The utility model discloses a fixed mode modified tool grinder of emery wheel, including motor 1, the main shaft 2 of being connected with the output shaft transmission of motor. In a specific application, the spindle 2 is driven to rotate by the motor 1. The spindle head 3 is fixedly connected to an end portion of the spindle 2, in this embodiment, as shown in fig. 2, a threaded hole is formed in the spindle head 3, an external thread is formed at an end portion of the spindle 2, and the spindle head 3 is screwed on the spindle 2 through the threaded hole and the external thread which are matched with each other. In one embodiment, the spindle head is connected to the main spindle by a reverse thread, i.e. the spindle head is screwed in a direction opposite to the direction of rotation of the main spindle. The spindle 2 is further connected with a locking ring 4 in a threaded manner, after the locking ring 4 is screwed, the locking ring 4 is tightly abutted to the end part of the spindle head 3, so that the spindle head 3 and the spindle 2 are locked together, and when the spindle rotates, the spindle head rotates along with the spindle.
As shown in fig. 2, the outer end of the stub shaft 3 is provided with a taper 9. The pyramid part is used for assembling the grinding wheel fixing seat.
In this embodiment, the grinding wheel holder 5 is provided with a tapered bore which is in tapered engagement with the tapered portion 9. The grinding wheel fixing seat 5 and the cone part 9 are locked together through a bolt 6 screwed in the center of the cone part. When the spindle nose rotates, the grinding wheel fixing seat 5 rotates along with the spindle nose 3.
As shown in fig. 2, a grinding wheel mounting boss 51 is provided on the grinding wheel fixing seat 5, the grinding wheel 7 is fitted over the grinding wheel mounting boss 51, and after the grinding wheel is fitted over the grinding wheel mounting seat, the side surface of the grinding wheel is brought into surface contact with the corresponding surface on the grinding wheel mounting boss.
The periphery of the locking ring 8 is covered on the grinding wheel 7, the locking ring 8 and the grinding wheel fixing seat 5 are locked together through screws, and the locking ring and the grinding wheel fixing seat tightly clamp the grinding wheel, so that the grinding wheel rotates along with the grinding wheel fixing seat when the grinding wheel fixing seat rotates.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
