Description
Technical field
The utility model belongs to transmission shaft field of locating technology, and in particular to one kind is positioned for chain type or belt drive shaft
Clamp device.
Background technique
In the kind of drive of mechanical equipment, there are gear drive, linked transmission and belt transmission.Linked transmission and belt pass
It is dynamic to be typically employed in long-distance transmission.Linked transmission process is to be connected by transmission shaft and sprocket wheel by chain, graduation speed change etc.
To realize transmitting power.Either linked transmission or belt are driven the requirement for having rate of tension, and the standard of being not up to will go out
Phenomena such as now jump tooth skids, quick abrasion.Therefore, the rate of tension of chain or belt must be adjusted at any time in operation process, it is ensured that
Equipment is normally driven.Currently, during linked transmission, in the gear especially more than second level, three of secondary transmission
Transmission shaft shape forms an angle, not in a plane, because adjustment the tensioning of the chain degree is mainly to adjust and fixed conveyor axis
Position, thus the adjustment direction of transmission shaft be it is unfixed, the adjusting range of general transmission shaft is set in a border circular areas, i.e.,
Transmission shaft and linked transmission body have a round adjustment space；Both ends of the drive shaft respectively has an adjusting seat or adjustment plate, adjustment
Seat or the vertical and horizontal of adjustment plate are fitted with adjustment silk, are withstood by adjustment silk and moved adjusting seat or adjustment plate, Lai Shixian
Then adjustment of the transmission shaft in round adjustment region will be adjusted so that the tensioning of the chain degree reaches standard with four fastening bolts
Bed rearrangement or adjustment plate and the steady fixation of body, to realize adjustment purpose.
Since fastening bolt used generally uses plain bolt, only bolt tail welds a baffle, and scene exists
Fastening effect is bad, is easy the problem of loosening；Bolt looseness causes adjustment plate or adjusting seat to loosen, and will cause adjustment silk bending and becomes
Shape, chain or belt slack, rate of tension cannot be guaranteed, prevent linked transmission equipment or belt drive device from running well, directly
Influence equipment operation rate is connect, being normally carried out for production is influenced.
Summary of the invention
The purpose of the utility model is to provide a kind of clamp devices positioned for chain type or belt drive shaft.
The purpose of this utility model is achieved through the following technical solutions:
The utility model relates to a kind of clamp devices positioned for chain type or belt drive shaft, including are arranged in transmission shaft
Round adjustment through-hole on body fuselage and the fastening assembly for adjusting and fastening transmission shaft, it is characterised in that: described is tight
Gu component is made of cylinder positioning seat and square head bolt, the cylinder positioning seat by top path boss and lower part it is big
Diameter cylinder is constituted, and the size of the path boss matches with the round adjustment through-hole on transmission shaft body fuselage, described
Cylinder positioning seat on, from the center of circle to major diameter cylindrical edge, along axial direction be provided with both sides be circular arc rectangular through holes, major diameter circle
The length direction two sides of the rectangular through holes of column are provided with interior straight-tooth I；The square head bolt is made of head and screw rod, in side
The both sides of the head of hook bolt is machined with the outer straight-tooth II to match with interior straight-tooth I；The screw rod of the square head bolt passes through cylinder
The outer straight-tooth II of rectangular through holes on positioning seat, square head bolt is engaged with the interior straight-tooth I on cylinder positioning seat, and is inserted into transmission
Then transmission shaft body is fixedly connected by corresponding fixing threaded hole on axis body with nut tightly with transmission shaft body fuselage.
The shape height of the path boss and the depth of round adjustment through-hole match.
The utility model has the advantages that:
The utility model structure is simple, and fastening locating effect is firm, persistently；On circle adjustment through-hole and cylinder positioning seat
Rectangular through holes precision-fit, gap is small, and the position for limiting transmission shaft is accurate, it is ensured that the rate of tension of chain or belt is normal, drop
Less trouble improves equipment operation efficiency；Dismounting and change is convenient and efficient simultaneously.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the cylinder positioning seat of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural schematic diagram of the square head bolt of the utility model.
Fig. 4 is the top view of Fig. 3.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As Figure 1-Figure 4, a kind of clamp device positioned for chain type or belt drive shaft of the utility model, including
Round adjustment through-hole on transmission shaft body fuselage and the fastening assembly for adjusting and fastening transmission shaft, four circles are set
Shape adjustment through-hole is generally four, it is characterised in that: the fastening assembly is made of cylinder positioning seat and square head bolt, institute
The cylinder positioning seat stated is made of the major diameter cylinder 2 of the path boss 1 on top and lower part, the size of the path boss 1 with
Round adjustment through-hole on transmission shaft body fuselage matches, on the cylinder positioning seat, from the center of circle to major diameter cylindrical edge
Edge is provided with the rectangular through holes 3 that both sides are circular arc along axial direction, is provided in the length direction two sides of the rectangular through holes of major diameter cylinder
Interior straight-tooth I 4；The square head bolt is made of head 6 and screw rod 5,6 two sides of the head of square head bolt be machined with it is interior straight
The outer straight-tooth II 7 that tooth I 4 matches；The screw rod 5 of the square head bolt passes through the rectangular through holes 3 on cylinder positioning seat, square toes
