Detailed Description
The technical scheme protected by the utility model is specifically explained in the following by combining the attached drawings.
The utility model provides a vertical machining center is with two handle ball finish chamfering frock, includes: main shaft 2 and equal altitude piece 1, main shaft 2 includes from last down in proper order: the ball-shaped support comprises a shaft lever 21, a shaft seat 22 and a base 23, wherein an expansion sleeve 3 is sleeved on the outer side of the shaft lever 21, the lower portion of the expansion sleeve 3 is abutted against the shaft seat 22, a taper sleeve 4 and a locking nut 6 are arranged above the expansion sleeve 3, an adjusting ring 5 is arranged between the taper sleeve 4 and the locking nut 6, a ball 7 is sleeved on the periphery of the expansion sleeve 3, a contact part 11 is arranged at the top of an equal-height block 1 and used for supporting a ball handle 71, a supporting part 12 is arranged at the bottom of the equal-height block 1 and used for supporting the equal-height block 1, and the ball handle 71 is clamped on the equal-height block 1.
In this embodiment, the contact portion 11 is provided in a V shape, and contacts with the outer circles of the knobs 71 at both ends of the sphere 7, so as to position the sphere 7 and bear the weight of the sphere. The bottom support 12 stands on the work top 8.
A plurality of through holes 25 are uniformly formed in the base 23 of the main shaft, and counter bores are adopted for placing hexagon socket head cap screws, so that the main shaft 2 can be firmly fixed on the working table surface 8.
The middle shaft lever of the main shaft 2 is used for placing an expansion sleeve 3, the expansion sleeve 3 is provided with a taper sleeve 4, an adjusting ring 5 and a locking nut 6, the outer edge of the shaft seat of the main shaft 2 is provided with an inclined plane which is used for matching with the taper of the expansion sleeve 3, and the inner ring and the outer taper of the same taper sleeve 4 are respectively matched with the shaft lever 21 and the expansion sleeve 3.
As key dimensions including the width and the height of the equal-height block 1, the height of the main shaft 2, the size of the taper inclined plane and the like are comprehensively considered according to the dimension of the DN200-DN400 sphere, the manufacturing of the tool is reduced as much as possible, the production cost is reduced, and different specifications can be realized by replacing the expansion sleeve 3.
The working process of the utility model is as follows: the main shaft 2 is fixed on a vertical processing table top 8, then the expansion sleeve 3, the taper sleeve 4, the adjusting ring 5 and the locking nut 6 are sequentially placed in the vertical processing table top, and the locking nut 6 is screwed in advance to be in contact with the adjusting ring 5. At the moment, the ball body 7 is hoisted, the inner hole of the ball body 7 penetrates through the main shaft 2, namely penetrates through the expansion sleeve 3, then the equal-height block 1 is placed according to the falling position of the ball body 7, the ball handles 71 on two sides lean against the V-shaped contact part of the equal-height block 1, the ball body is tightly pressed on the equal-height block 1 due to the self weight of the ball body, and the ball handles 71 after finish machining have very good concentricity and very small outer circle size of the ball handles, so that the ball body 7 is ensured to be in contact with the equal-height block 1 through the two ball handles and on the same plane, and the machining precision is ensured. Only need screw up lock nut 6 this moment, promote regulating ring 5 to promote taper sleeve 4, final purpose promotes the cover 3 that expands, makes the cover 3 that expands expand to the downthehole direction tight, not smooth fixed good spheroid when expanding tightly, and the hole is rectified automatically simultaneously, is equivalent to proofreaying the drill way, and the workman only needs the operation to add immediately, uses the handle as the center, and processing drill way round can, and add man-hour as long as first piece proofreaies can. After the processing is finished, the other end is processed by turning the head in the same way. Therefore, the processing precision is high, and the production efficiency is high. When the ball bodies with different specifications need to be processed, the expansion sleeve 3 is usually replaced.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
