Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1 to 4, the following technical solutions are adopted in the present embodiment: the utility model provides a centre gripping frock for elbow fitting part, including base 1, U type supporting shoe 3, briquetting 4, first bolt 5, base 6 and second bolt 7, be provided with the U type recess identical with the elbow fitting terminal surface in the middle of the base 1, U type recess top is provided with briquetting 4, briquetting 4 supports through U type supporting shoe 3, briquetting 4 and base 1 are provided with screw hole 2 in same axle center, screw hole 2 cooperatees with first bolt 5, base 1 is fixed with base 6 through second bolt 7.
It is worth noting that the lower plane of the pressing block 4 is also provided with a U-shaped groove matched with the upper plane of the elbow joint.
It should be noted that the U-shaped support block 3 is a support block with adjustable height.
In addition, the base 6 is in clamping fit with a numerical control machine tool chuck.
Before the part is machined, the short end face of the elbow joint is placed on the base 1, a U-shaped groove is formed in the middle of the base 1, the design size of the groove is matched with the size of the end face of the elbow joint, and the positioning accuracy of the part is guaranteed. Briquetting 4 is supported by U type supporting shoe 3, and U type supporting shoe 3, briquetting 4 are equipped with the screw hole 2 of same axle center with base 1, and the three is accomplished through first bolt 5 and is connected, and 4 lower planar designs of briquetting have U type recesses moreover, cooperate with the plane on the part, guarantee the clamping steadiness of part through turning round tight first bolt 5. When the same type of parts are machined, the clamping height can be adjusted by changing the height of the U-shaped supporting block 3. And finally, the base 1 is connected with the base 6 through a second bolt 7, and the numerical control machine tool chuck directly clamps the base 6 to finish the turning of the bent pipe type part.
The tool of the specific embodiment is simple in structure and convenient to operate, can ensure the machining precision of parts and improve the production efficiency, and has a certain protection effect on the surfaces of the parts to ensure the product quality.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
