Abstract
Process a turning tool for tommyhead bolt, relate to the process technology of tommyhead bolt.It is loaded down with trivial details in order to solve traditional tommyhead bolt process operation, causes working (machining) efficiency low, and the serious problem of waste of raw materials.The utility model comprises carcass, large block, top and little block, and in the top hole that is mounted in carcass center, the surface of carcass is provided with the screwed hole for fixing large block and little block.According to the size of tommyhead bolt square toes, select large block or little block, and large block or little block are arranged on carcass.A kind of turning tool processing tommyhead bolt of processing tommyhead bolt described in employing present embodiment, does not need to reserve the long process area of 5mm, adds and does not need to remove this process area man-hour yet, can save material, reduces manufacturing procedure, raises the efficiency, and reduces the cost of raw material.The utility model is applicable to the processing of tommyhead bolt.
Description
Technical field
The utility model relates to the process technology of tommyhead bolt.
Background technology
Shearer hauled-part docks the tommyhead bolt of use with intermediate box, due to the restriction of installing space, threaded shank becomes eccentric shape with its head, as depicted in figs. 1 and 2.Because coal-winning machine model is different, the tommyhead bolt of use is also different.
Former tommyhead bolt rough forging top head lengthens 5mm, as process area, uses.When rough turn, the first car of tommyhead bolt head goes out 5mm process area, and this process area is coaxial with threaded shank, and then chuck is clamped process area, and the other end, with top very good, completes the turning of screw portion.After screw portion car is good, turns over and process trolley is fallen.This processing technology operation is loaded down with trivial details, and working (machining) efficiency is low, and waste of raw materials is serious, has increased cost.
Utility model content
The purpose of this utility model is loaded down with trivial details in order to solve traditional tommyhead bolt process operation, causes working (machining) efficiency low, and the serious problem of waste of raw materials, and a kind of turning tool of processing tommyhead bolt is provided.
A kind of turning tool of processing tommyhead bolt described in the utility model comprises carcass, large block, top and little block;
Described large block comprises a disk and a cylinder, the diameter of a described disk is greater than the diameter of the end face of a cylinder, a disk is fixed on one end of a cylinder, and the central shaft of a disk overlaps with the central shaft of a cylinder, and the other end of a cylinder is provided with external screw thread;
Described little block comprises No. two disks and No. two cylinders, the diameter of described No. two disks is greater than the diameter of the end face of No. two cylinders, and be less than the diameter of a disk, No. two disks are fixed on one end of No. two cylinders, and the central shaft of No. two disks overlaps with the central shaft of No. two cylinders, and the other end of No. two cylinders is provided with external screw thread;
Described top No. three disks and No. three cylinders of comprising, the diameter of described No. three disks is greater than the diameter of the end face of No. three cylinders, a plane of these No. three disks is fixed on an end face of No. three cylinders, and the central shaft of No. three disks overlaps with the central shaft of No. three cylinders, in another plane of No. three disks, be provided with protruding conical structure, the central shaft of the central shaft of this conical structure, No. three disks and the central shaft of No. three cylinders overlap;
The center of carcass is the through hole with step, top being mounted in this through hole, and the surface of carcass is provided with the screwed hole for fixing large block and little block.
Adopt a kind of turning tool processing tommyhead bolt of processing tommyhead bolt described in the utility model, do not need to reserve the long process area of 5mm, add and also do not need to remove this process area man-hour, can save material, reduce manufacturing procedure, therefore raise the efficiency, reduce the cost of raw material.

Fig. 1 is the front view of the structural representation of the tommyhead bolt in background technology;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the front view of the structural representation of a kind of described in embodiment one turning tool of processing tommyhead bolt;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1 to Fig. 4, present embodiment is described, a kind of turning tool of processing tommyhead bolt described in present embodiment comprises carcass 1, large block 2, top 3 and little block 4;
Described large block 2 comprises a disk and a cylinder, the diameter of a described disk is greater than the diameter of the end face of a cylinder, a disk is fixed on one end of a cylinder, and the central shaft of a disk overlaps with the central shaft of a cylinder, and the other end of a cylinder is provided with external screw thread;
Described little block 4 comprises No. two disks and No. two cylinders, the diameter of described No. two disks is greater than the diameter of the end face of No. two cylinders, and be less than the diameter of a disk, No. two disks are fixed on one end of No. two cylinders, and the central shaft of No. two disks overlaps with the central shaft of No. two cylinders, and the other end of No. two cylinders is provided with external screw thread;
Described top 3 comprise No. three disks and No. three cylinders, the diameter of described No. three disks is greater than the diameter of the end face of No. three cylinders, a plane of these No. three disks is fixed on an end face of No. three cylinders, and the central shaft of No. three disks overlaps with the central shaft of No. three cylinders, in another plane of No. three disks, be provided with protruding conical structure, the central shaft of the central shaft of this conical structure, No. three disks and the central shaft of No. three cylinders overlap;
The center of carcass 1 is the through hole with step, and top 3 are mounted in this through hole, and the surface of carcass 1 is provided with the screwed hole for fixing large block 2 and little block 4.
As shown in Figure 3, in present embodiment, top 3 are arranged in the hole at carcass 1 center, No. three disk is positioned on the step in hole, the tip of conical structure outwardly, according to the size of tommyhead bolt square toes, select large block 2 or little block 4, and large block 2 or little block 4 are arranged on carcass 1, the screwed hole that on carcass 1, the distance to top 3 is less than for fixing little block 4 for the screwed hole of fixing large block 2 arrives top 3 distance.As shown in Figure 4, when tommyhead bolt square toes are larger, use little block 4, when tommyhead bolt square toes hour are used large block 2.Tommyhead bolt total length car is got well and process two ends centre bore.First by a kind of turning tool of processing tommyhead bolt described in present embodiment on lathe, then tommyhead bolt square toes one end is withstood on to top 3 tip of described frock, the tommyhead bolt other end withstands on tailstock centre, according to the size of tommyhead bolt square toes, come the large block 2 of choice for use or little block 4 to make its orientation, complete the turning of screw portion.
