Corruption and leakproofness substantially prolong the service life of valve.However, such material has very high hardness, in process
In, there is difficult when many technical problems, the especially surface of processing hollow ceramic spheres workpiece (with penetrating centre bore)
With operation.Since spheres of ceramic workpiece itself has non-conductive and non-magnetic property, i.e., ceramic sky can not be carried out with magnetic force chuck
The processing of bulbus cordis body, the spherical workpieces of spherical structure make fixture be difficult to carry out accurate, securely clamping, and processing efficiency also compared with
It is low.
Utility model content
The utility model provides one kind to solve shortcoming in the prior art convenient for operating, being easy to clamping, clamping
Firm, workpiece picks and places efficiently hollow ceramic spheres workpiece surface processing and uses clamping device.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of hollow ceramic spheres workpiece table
Face processing uses clamping device, including ladder mandrel, ladder mandrel to be followed successively by lathe clamping part and clamping workpiece portion by left end to the right side,
The right side top in clamping workpiece portion is provided with rotary fastening hold-down mechanism；
Fastening hold-down mechanism includes fixing axle and compact heap, the centerline parallel of fixing axle in the center line of ladder mandrel,
The left end of fixing axle is fixedly connected on the right side top in clamping workpiece portion, offers eccentric orfice on compact heap, on compact heap
Eccentric orfice covers in fixing axle, and the right hand external of fixing axle is threaded with locking nut, compresses block edge and fixed axis center
Farthest distance is less than or equal to fixed the distance between shaft centre line and one bus of clamping workpiece portion lowest part between line.
The left part in clamping workpiece portion is arranged with washer, and the outer diameter of washer is greater than the outer diameter of lathe clamping part.
The right side of compact heap is provided with handle.
By adopting the above technical scheme, the utility model has following technical effect that
The lathe clamping part of the utility model is clamped on the main shaft of lathe, before spheres of ceramic work pieces process,
Then the left part mounting gasket in clamping workpiece portion, washer and lathe clamping part right end face contact are installed spheres of ceramic workpiece
Onto clamping workpiece portion, hand-held handle by compact heap be rotated up and with spheres of ceramic workpiece right end face contact, turn locking screw
Mother, locking nut press compact heap, and spheres of ceramic workpiece and ladder mandrel are simultaneously fixed as by compact heap compacted ceramic spherical workpieces
One, lathe starting drive multi-diameter shaft and spheres of ceramic workpiece rotation, grinding knife tool or grinding wheel to carry out table to spheres of ceramic workpiece
Face grinding.After the completion of grinding, unscrew locking nut, stir handle or compact heap with hand and be rotated down by self gravity,
Due to compress block edge between fixed shaft centre line it is farthest at a distance from be less than or equal to fixed shaft centre line and clamping workpiece portion most
The distance between one bus in lower part can ensure that compact heap will not protrude from the right side in clamping workpiece portion, thus will not in this way
Spheres of ceramic workpiece is stopped to take out to the right or install to the left.Only it need to unscrew locking nut, without backing out locking from clamping workpiece portion
Nut greatly improves working efficiency so as to shorten the time for installing and taking out spheres of ceramic workpiece.
Washer is located at the hierarchic structure of multi-diameter shaft, can allow on the right side of spheres of ceramic workpiece with hierarchic structure contact position stress
Uniformly, positioning action is played to spheres of ceramic workpiece；Compact heap is a kind of eccentric mounting structure, is used to by operation handle to work
Part is rapidly assembled and disassembled；Locking nut is to play pressuring action to above-mentioned washer, spheres of ceramic workpiece, compact heap.
In conclusion the utility model have many advantages, such as it is reasonable in design, easy to use, pass through clamped one time, operation
Simply, the time is saved, processing efficiency is improved, it is ensured that the machining accuracy of sphere guarantees the quality of grinding.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of hollow ceramic spheres workpiece surface the processing clamping device, including ladder of the utility model
Mandrel, ladder mandrel are followed successively by lathe clamping part 1 and clamping workpiece portion 2, the right side top in clamping workpiece portion 2 by left end to the right side
It is provided with rotary fastening hold-down mechanism.
Fastening hold-down mechanism includes fixing axle 3 and compact heap 4, and the centerline parallel of fixing axle 3 is in the center of ladder mandrel
Line, the left end of fixing axle 3 are fixedly connected on the right side top in clamping workpiece portion 2, offer eccentric orfice on compact heap 4, compress
Eccentric orfice on block 4 covers in fixing axle 3, and the right hand external of fixing axle 3 is threaded with locking nut 5,4 edge of compact heap with
