Description
Technical Field
The utility model relates to a fastening frock technical field, specifically speaking relates to a fastening frock.
Background
In the machining process, the utilization rate of the tool is high, and particularly for the machining of batch workpieces, the tool can greatly improve the production efficiency, ensure the product quality and bring greater benefits to companies. When the end face and the excircle of the grinding wheel base body with the inner hole are machined, if the excircle is clamped by a chuck, the excircle cannot be completely trimmed because a clamping jaw is fixed on the chuck; if the inner hole is internally supported by the chuck, because the chuck has a part of protruding base body, when the end face is processed, the end face close to the jaw part can not be trimmed, and therefore, the outer circle and the end face can be simultaneously and completely processed by considering the design of a set of fastening tool.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a fastening tool that overcomes some or all of the disadvantages of the prior art.
According to the utility model discloses a fastening frock, it includes fastening frock, fastening frock includes rear portion and front portion, anterior diameter is less than rear portion and anterior round platform form that is, the anterior front side is equipped with the jack, jack circumference is equipped with a plurality of elongated slots, and a tapering bolt can insert in the jack.
Preferably, the front sleeve is provided with a workpiece, the front side of the workpiece protrudes out of the front part, and the diameter of the workpiece is larger than that of the rear part.
Preferably, one end of the long groove is communicated with the jack, and the other end of the long groove is communicated with the side face of the front part.
Preferably, the number of the long grooves is 6 or 8.
Preferably, the smallest diameter of the taper bolt is equal to the diameter of the insertion hole.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the utility model discloses a tapering bolt inserts the jack, makes the anterior diameter grow of fastening frock to chucking work piece can make the equal protrusion frock of excircle and terminal surface of work piece effectively, to the processing of terminal surface and excircle when satisfying one-time dress card, promoted machining efficiency.

In the figure: 110. fastening tooling 111, rear part 112, front part 120, insertion holes 130, long grooves 140, taper bolts 150 and workpieces.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Examples
As shown in fig. 1 and fig. 2, the present embodiment provides a fastening tool, which includes a fastening tool 110, where the fastening tool 110 includes a rear portion 111 and a front portion 112, the diameter of the front portion 112 is smaller than that of the rear portion, the front portion 112 is in a circular truncated cone shape, a plug hole 120 is disposed on a front side of the front portion 112, a plurality of elongated slots 130 are circumferentially disposed on the plug hole 120, and the taper bolt 140 can be inserted into the plug hole 120.
In this embodiment, the front portion 112 is sleeved with a workpiece 150, the front side of the workpiece 150 protrudes out of the front portion 112, and the diameter of the workpiece 150 is larger than that of the rear portion 111.
In this embodiment, one end of the long slot 130 is communicated with the insertion hole 120, and the other end of the long slot 130 is communicated with the side surface of the front portion 112.
In this embodiment, the number of the long slots 130 is 6 or 8.
In this embodiment, the minimum diameter of the tapered bolt 140 is equal to the diameter of the insertion hole 120.
The rear part 111 is used for being clamped on a chuck for fixing, the rear end face of the workpiece 150 is directly attached to the front side face of the rear part 111 when being installed, the workpiece can be leveled for the first time, and frequent leveling is not needed subsequently; the diameter and thickness of the front portion 112 are determined by the inner bore of the workpiece 150, the front portion 112 has a small taper, the diameter of the foremost end is the smallest to facilitate the installation of the workpiece, and the thickness of the front portion 112 is slightly less than the thickness of the workpiece 150. After the workpiece 150 is mounted and clamped on the front part 112, the tapered bolt 140 is inserted into the insertion hole 120 and screwed forward until the workpiece 150 is fastened, and the tapered bolt 140 is lower than the end face of the workpiece 150 so as to perform integral machining of the end face. Adopt this fastening frock with low costs, processing is convenient, and the satisfying that again can be fine is once adorned the card and is simultaneously to the processing of terminal surface and excircle, has promoted machining efficiency.
After the workpiece 150 is placed on the conical surface of the front part 112, the conical bolt 140 is inserted into the insertion hole 120, the conical surface is gradually jacked up in the process of going deep into the insertion hole 120 due to the certain diameter of the conical bolt 140, the size of the front end of the front part 112 is easy to increase due to the long groove 130, the original gap between the workpiece 150 and the conical surface can be easily moved, the gap between the workpiece 150 and the conical surface is gradually reduced to be in contact and fastened due to the acting force of the conical bolt 140 to the periphery of the insertion hole 120, and the purpose of fastening the workpiece 150 is achieved. After the tool is used, the outer surface of the workpiece 150 does not need to be fixed, and the end face of the whole workpiece 150 can be directly and completely machined.
To sum up, the utility model discloses a tapering bolt inserts the jack, makes the anterior diameter grow of fastening frock to chucking work piece can make the equal projecture frock of excircle and terminal surface of work piece effectively, to the processing of terminal surface and excircle when satisfying the dress card, promoted machining efficiency.
The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
