Description
Technical field
The utility model relates to sprocket wheel manufacture field more particularly to a kind of auxiliary bodies that sprocket wheel keyway opens up.
Background technique
Sprocket wheel refers to the wheel with cog type whelp, mutually to nibble with the accurate block of pitch on pitch chain ring or cable
It closes, currently, sprocket wheel is widely used in the machine driving of the industries such as chemical industry, textile machine, food processing, instrument, petroleum
Deng.
Sprocket wheel usually all offers keyway, and opening up keyway by broaching machine is a kind of common processing method.Two synchronous chains
The use of wheel is very extensive, in order to improve the synchronous effect of two sprocket wheels, at present usually using broaching machine progress simultaneous processing, and
When synchronizing processing, positioning is more difficult, lacks dedicated auxiliary body.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of auxiliary body that sprocket wheel keyway opens up, background is effectively solved
The problem of being pointed out in technology.
The technical solution adopted in the utility model is:
A kind of auxiliary body that sprocket wheel keyway opens up, including central axis, positioning plate and locating rod, the central axis is along axis
To keyway broach slot is offered, the keyway broach slot runs through the both ends of central axis, and described positioning plate one end is equipped with lantern ring, institute
The one end for stating lantern ring and central axis connects and fixes, and the lantern ring is fixed with one to the convex of lantern ring central protuberance in the side of positioning plate
Platform, the cross section of the boss are semicircle, offer the groove to match with boss in the outside cambered surface of the central axis,
The groove extends upward through central axis in the axis of central axis, the positioning plate and perpendicular, the described locating rod of central axis
The other end of the positioning plate relative to central axis is set, the locating rod is mutually perpendicular to positioning plate, the locating rod and
Central axis is located at the same side of positioning plate.
When in use, central axis protrudes into the centre bore of two sprocket wheels, and locating rod matching stretches two and enters any one of sprocket wheel
To in tooth socket, this makes it possible to position to two sprocket wheels, the keyway position processed in this way by broaching machine is almost
Identical, to promote the synchronous effect of the two sprocket wheels, the design of boss and groove is able to ascend between central axis and positioning plate
Positioning accuracy.
Preferably, offering external screw thread outside described locating rod one end, the positioning plate is relative to central axis
The other end offers one and the perpendicular threaded hole of positioning plate, and the threaded hole and the external screw thread of locating rod one end match,
The locating rod opens up the other side that externally threaded one end extends to positioning plate across positioning plate, and the locating rod is opening up external screw thread
One end matching be equipped with a nut.
Locating rod can select different size of locating rod according to the tooth socket of different sizes using the structure unloaded is opened
It is positioned, has saved the deposit of auxiliary body, environmental protection and energy saving, locating rod matches with threaded hole and nut simultaneously, solid
It forms self-locking after fixed, improves the firmness of locating rod.
Preferably, the width of the positioning plate is less than the diameter of lantern ring.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below by specific embodiment and in conjunction with attached drawing, the utility model is further described in detail.
Embodiment 1
As shown in Figure 1, a kind of auxiliary body that sprocket wheel keyway opens up, including central axis 1, positioning plate 2 and locating rod 3, institute
The central axis 1 stated is provided in the axial direction with keyway broach slot 4, and the keyway broach slot 4 runs through the both ends of central axis 1, described fixed
Position 2 one end of plate is equipped with lantern ring 5, and one end of the lantern ring 5 and central axis 1 connects and fixes, and the lantern ring 5 is in the side of positioning plate 2
It is fixed with a boss 6 to 5 central protuberance of lantern ring, the cross section of the boss 6 is semicircle, the outside of the central axis 1
The groove 7 to match with boss 6 is offered in cambered surface, the groove 7 extends upward through central axis 1 in the axis of central axis 1, described
Positioning plate 2 and central axis 1 it is perpendicular, the other end of the positioning plate 2 relative to central axis 1 is arranged in the locating rod 3, described
Locating rod 3 be mutually perpendicular to positioning plate 2, the locating rod 3 and central axis 1 are located at the same side of positioning plate 2.
External screw thread 8 is offered outside described 3 one end of locating rod, the positioning plate 2 is in the other end relative to central axis 1
