Description

Hob sharpening grinder

This creation is about a processing machine, especially a machine for grinding a hob.

The hob is a gear machining tool arranged in a spiral line along a cylinder or a cone for machining cylindrical gears, worm gears and other cylindrical toothed workpieces according to the development method. Depending on the application, the hob is divided into a gear hob, a worm wheel hob, a non-involute wire hob and a fixed hob.

When the hob is passivated and needs to be ground, it is customary to use a hob to sharpen the grinder and use a hob to sharpen the grinding wheel of the grinder to maintain the sharpness it deserves. However, the conventional hob sharpening grinder has some disadvantages that still need to be improved: First, when the hob sharpens the grinding wheel of the grinding machine, a slight vibration is inevitable, and if the vibration continues to occur and cannot be reduced, , will inevitably affect the accuracy and precision of the grinding; Second, the conventional hob sharpening grinder is used to grind the hob, the user is located on the front side of the hob sharpening grinder, and the processing is located in the roll The back side of the knife, so the machining position is blocked by the hob itself and cannot be directly observed by the user, which is inconvenient in use.

In view of this, the creator conceived and further studied, and finally created a hob sharpening grinder.

The present invention provides a hob sharpening grinder whose main purpose is to reduce the vibration of the grinding wheel of the hob sharpening grinder while grinding the hob, and the user can directly observe the processing place.

In order to achieve the foregoing objective, the present invention provides a hob sharpening grinder comprising: a base for an object mounting assembly; a platform slidingly disposed on the base to provide a plane for processing, the platform being freely Displaceing in the X direction relative to the base; a main frame disposed on one side of the platform, the main frame having a tool chuck, the tool chuck having a rotation axis in the X direction; a tail frame disposed at the On the other side of the platform, the tailstock has a joint portion, the shaft of the joint is in the X direction and coaxial with the rotation axis of the cutter chuck; a stand is slidably disposed on the base and is freely opposed to the base The base is displaced in the Y direction, the vertical frame faces the main frame and the tail frame with a sliding member, the sliding member is freely displaced relative to the vertical frame in the Z direction, and the sliding member is provided with a grinding wheel. The grinding wheel is fixed on the working surface by a built-in main shaft, wherein the grinding wheel is located on the XZ plane, and the shaft of the grinding wheel is located in the Y direction; and a sand fixing seat is fixed on the platform .

The present invention utilizes the provided hob sharpening grinder to obtain the effect that the grinding wheel is fixed to the actuating surface by a built-in spindle, and the built-in main shaft is used to shorten the grinding wheel projection as much as possible. The length of the actuating surface is reduced, thereby reducing the moment during construction to reduce the grinding wheel of the hob sharpening grinder when grinding the hob Vibration; in addition, the grinding wheel system is located on the XZ plane, and the shaft of the grinding wheel is located in the Y direction. Therefore, the machining position is located on the upper side of the hob, and the user can directly observe from the front side of the hob sharpening grinding machine. Processing office.

The techniques, means, and other effects of the present invention in order to achieve the above objects are set forth in the accompanying drawings.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [Simplified Description of the Drawings] for details: The preferred embodiment of the creative hob sharpening grinder 1 and 4, comprising: a base 20, a platform 21, a main frame 30, a tailstock 40, a stand 50 and a sand repairing seat 22, wherein: the base 20 is for object installation Group setting The platform 21 is slidably disposed on the base 20 to provide a plane for processing. The platform 21 is freely displaced in the X direction relative to the base 20; the main frame 30 is fixed on one side of the platform 21, The main frame 30 has a tool chuck 31 having a rotating shaft in the X direction, and the tool chuck 31 is coupled to a low backlash high precision worm gear reducer 32 mounted on the main frame 30. Connected and rotated by the low backlash high precision worm gear reducer 32; the tailstock 40 is disposed on the other side of the platform 21, the tailstock 40 has a joint portion 41, and the shaft portion of the joint portion 41 In the X direction, and coaxial with the rotating shaft of the tool chuck 31, the two ends of the hob 70 are fixed to the tool chuck 31 and the joint portion 41; the stand 50 is slidably disposed on the base 20, and Freely displaced in the Y direction relative to the base, the stand 50 faces the main frame 30 and the tailstock 40 with the acting surface 511 of a sliding member 51, and the sliding member 51 is freely along the vertical frame 50 along the Z In the directional displacement, the grinding surface 51 of the sliding member 51 is provided with a grinding wheel 52 having an inclined surface 521 on the outer side thereof. More specifically, the grinding wheel 52 The wheel 52 is fixed to a cross roller strut group 54 in the sliding member 51 by a built-in main shaft 53. The grinding wheel 52 is located on the XZ plane, and the shaft of the grinding wheel 52 is located in the Y direction. And the sand dressing seat 22 is fixed on the platform 21, and the sand dressing seat 22 has a grinding wheel modification surface 221 .

The above is the main components of the creation embodiment and its configuration description. For the usage and efficacy of this creative embodiment, please refer to Figure 2 for the first As shown in FIG. 1 , the grinding wheel 52 of the present invention is fixed to a cross roller strut group 54 in the sliding member 51 by a built-in main shaft 53 , and is passed through the built-in main shaft 53 to shorten the position as much as possible. The grinding wheel 52 protrudes from the length of the actuating surface 511, thereby reducing the moment during construction to reduce the vibration of the grinding wheel 52 of the hob sharpening grinder during grinding of the hob.

It is worth mentioning that, referring to Fig. 3, as shown in Fig. 1, the grinding wheel 52 is located on the XZ plane, and the shaft of the grinding wheel 52 is located in the Y direction. In other words, the grinding wheel 52 is longitudinally disposed. And the grinding wheel that is different from the conventional hob sharpening grinder is set horizontally. Therefore, the conventional grinding wheel system sharpens the rear side of the sharpening cutter, and the grinding wheel 52 of the present invention sharpens the upper side of the sharpening cutter 70, and the user can directly observe the processing portion from the front side of the hob sharpening grinding machine, so as to facilitate Construction operation.

In addition, please refer to FIG. 4 in conjunction with FIG. 1 and FIG. 2, in the case of the hob sharpening grinder of the present invention, the grinding wheel 52 is in contact with the hob 70, not located in the hob 70. The axis, in order to improve the precision of the grinding, so that the processing surface of the hob 70 achieves the precision required by the manufacturer. Further, the grinding wheel 52 processes the hob 70 with its inclined surface 521.

In addition, as shown in Figures 1 and 3, the sand-removing seat of the present invention is fixed on the platform, and the sand-removing seat is different from the conventional sand-fixing seat on the main frame. The sand repairing seat is closer to the grinding wheel, which can save construction time and improve work efficiency.

It is known from the above that this creation is indeed in line with "industry availability", "novelty" and "progressiveness". Please give us a review and grant a patent as soon as possible.
