Abstract
The utility model discloses a truing device for external threads of a shaft end, comprising a machine tool main shaft, a bolt, a connecting sleeve, a tension bolt, a safety pin, a shell, a screw die and a guide sleeve, wherein the main machine tool shaft and the connecting sleeve sheathed outside the machine tool main shaft are connected into a whole by the bolt; a conical shaft with the shell upward is inserted into an inner hole of the machine tool main shaft and is connected with the machine tool main shaft in a positioning manner, and a downward flange at the other end is internally provided with a coaxial stepped blind hole; and the shell and the connecting sleeve are axially connected by the tension bolt to form a linking structure. The screw die arranged in the shell is screwed into the shell and axially limited by the guide sleeve, and the safety pin screwed into the shell longitudinally is inserted into a crescent hole of the screw die by a small shaft end so as to form an overload protecting structure. In the truing device, by means of driving of the main shaft of a drilling machine or a lathe, correction on external threads of the shaft end of a workpiece is realized by using the screw die; and the truing device has the obvious characteristics of economy, practicability, labor-saving operation, stable quality and high truing efficiency and the like, and is especially suitable for truing the external threads of the shaft end in large-batch production.
Description
Technical field
The utility model relates to a kind of device of machining screw thread, and specifically, the utility model relates to a kind of axle head external screw thread trimming device.
Background technology
Common axle head is provided with externally threaded part in the plant equipment, and for example the axle head of automobile master gear shaft is provided with the external screw thread of M45 * 1.5mm.The part that this kind screw thread exposes structure easily is bruised, bumps hair in production process circulation process, its result directly reduces the externally threaded quality of connection of axle head.In order to eliminate above-mentioned sheltering a little, be necessary the axle head external screw thread is repaired, avoid loss as much as possible.At present, have two kinds of technology can realize the reparation of axle head external screw thread in the engineering, a kind of is to realize finishing by grinding, and another kind is made mantle fiber with the standard component screw die and handled.Above-mentioned two kinds of external screw thread dressing technique are very ripe, are widely used in the industrial production.But grinding external screw thread technology is the basic fundamental condition with expensive special purpose grinder, and this technology dressing quality is good, but production efficiency is poor, only is fit to high, smart axle head external screw thread finishing, uses thus to have significant limitation.Fairly simple with standard component screw die mantle fiber finishing external screw thread, do not need special equipment, only get final product by manual operations, this technology is simple, but operative employee's labour intensity is big, production efficiency is poor, equally also is not suitable for using in production in enormous quantities.Generally speaking, prior art is feasible, practical, and it is externally threaded to reach the finishing axle head, and all not all roses, improved necessity possesses skills.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, convenient, laborsaving, the axle head external screw thread trimming device that dressing quality is good and dressing efficiency is high.
The utility model is achieved through the following technical solutions technical goal.
Axle head external screw thread trimming device, it comprises machine tool chief axis, bolt, adapter sleeve, turnbuckle, safety pin, housing, screw die and fairlead.The adapter sleeve of the outer suit of described machine tool chief axis links into an integrated entity by bolt.The described housing axis of cone is up inserted in the machine tool chief axis endoporus and is located by connecting, and the other end is established coaxial step-shaped blind hole in lower flange, axially connect and compose linkage structure by turnbuckle between housing and the adapter sleeve.To being connected, fairlead minor diameter endoporus equals workpiece axle head diameter value, both matched in clearance to described fairlead by screw thread and housing shaft.Its improvements are: described screw die horizontal is installed in the housing endoporus, axially by the fairlead restriction that screws in, vertically screws in 2～3 safety pins in the housing and inserts in the screw die crescent moon hole with little axle head and constitute overcurrent protection structure.
In the said structure, the little axle head total cross section of safety pin shear strength equals screw die and can bear maximum cutting force, in case the little axle head of excess load safety pin is cut off the machine safety that plays protection axle head external screw thread trimming device and match.
The utility model compared with prior art has following good effect:
1, device is attached on the machine tool chief axis, and it is simple in structure, cost of manufacture is cheap;
2, machine tool chief axis directly drives, and repairs rapid operation, steady quality, the dressing efficiency height;
3, built-in safeguard construction, safe in utilization, reliable.
Description of drawings
Fig. 1 is that the utility model structure master looks schematic diagram.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Axle head external screw thread trimming device shown in the drawings, it comprises machine tool chief axis 1, bolt 2, adapter sleeve 3, turnbuckle 4, safety pin 5, housing 6, screw die 7 and fairlead 8.In the present embodiment, machine tool chief axis 1 is the spindle end of upright drill, the utility model and the interlock of drill press spindle end, and concrete syndeton is made of following several respects.At first, the overcoat load takes over 3 on machine tool chief axis 1, and both link into an integrated entity by bolt 2.Then will be located by connecting in housing 6 axis of cone insertion machine tool chief axis 1 endoporus up, the other end is established coaxial rank shape blind hole in lower flange, axially connect and compose linkage structure by turnbuckle 4 between housing 6 and the adapter sleeve 3.Housing 6 endoporus horizontal are installed screw die 7, and fairlead 8 screws in axial restraint screw die 7 from housing 6 bottoms, vertically screw in 2 safety pins 5 from housing 6 upper surfaces, and safety pin 5 inserts with little axle head and constitutes the overload safety structure in the screw die crescent moon hole.Present embodiment axle head external screw thread is M45 * 1.5mm, and it repairs externally threaded maximum cutting force is 200～500N ﹒ m.Cutting force is less than the shear strength of 2 safety pin 5 little axle heads in the dressing process, and then finishing is carried out smoothly.In case when finishing, cutting force was greater than joining safety pin 5 shear strength, the little shaft part of safety pin 5 ruptures, and is set fully to load because of super large with protective device and institute and damages.
The utility model is installed on the horizontal lathe, reaches the technique effect of the foregoing description under the protecting and leading of fairlead 8 equally.
The utility model drives by the main shaft 1 of drilling machine or lathe, realize repairing with 7 pairs of workpiece axle heads of standard component screw die external screw thread, have economical and practical, rapid operation, steady quality, characteristics such as dressing efficiency height are particularly suitable for finishing axle head external screw thread in the mass production.
