Abstract
The utility model provides a kind of frock clamp of nylon wheel, including：Fixing tool and movable tooling, the fixing tool and the movable tooling are in the form of annular discs, the inner surface of the fixing tool is evenly distributed with several first boss, the first boss is provided with alignment pin, the inner surface of the movable tooling is evenly distributed with several second boss, and the second boss is provided with positioning hole corresponding with the alignment pin and through the movable tooling.The frock clamp of nylon wheel of the present utility model, it can ensure that nylon wheel can not be ensure that the front and rear dimensionally stable uniformity of nylon wheel processing, finally ensure that the dimensional accuracy of nylon wheel when machining clamping by radial and axial external force using the frock clamp.
Description
Technical field
It the utility model is related to technical field of tooling clamps, more particularly to a kind of frock clamp of nylon wheel.
Background technology
The installation way of traditional nylon wheel processing is to use scroll chuck, also has three kinds using clamping with three-jaw chuck nylon wheel
Mode.First, can using three-jaw outwards in support it is empty by the way of, but so have two drawbacks：In processing nylon wheel endoporus and rope
During groove, in order to ensure the concentricity of endoporus and grooving, it is necessary to clamped one time processes endoporus and grooving, otherwise it cannot be guaranteed that its
Concentricity, but clamping could be processed this installation way needs twice；Because nylon material has certain elasticity, nylon is so allowed
Wheel by radial direction power, after easily nylon wheel being allowed to have radial deformation, such clamping to process, under dismounting after, nylon wheel unloads power
It can resile, so original processing dimension cannot ensure, serious meeting produces the phenomenon of three crests, so in elevator
Resonance can be caused during operation, unsafe factor be present.Second, the mode of the step of wheel hub is pressed from both sides with three-jaw, can guarantee that wheel endoporus
It is that clamped one time completes processing with grooving, ensures the concentricity of endoporus and grooving, but have radial force, can also after dismounting
Resile, it is impossible to ensure the consistent of processing dimension.3rd, with the mode of three three fabrication holes of claw clip, this mode not only can
There is the radial load of the above, there is also the power of wheel hub and the axile displacement of wheel rim opposite direction, cause nylon wheel wheel bore and rope
Groove is not in same center line, or even occurs when nylon wheel operates there is the phenomenon to swing.
Utility model content
The purpose of this utility model is to provide a kind of guarantee nylon wheel not by axial force and the frock of the nylon wheel of radial load
Fixture.
The utility model provides a kind of frock clamp of nylon wheel, including：Fixing tool and movable tooling, the fixation
Frock and the movable tooling are in the form of annular discs, and the inner surface of the fixing tool is evenly distributed with several first boss, described
First boss is provided with alignment pin, and the inner surface of the movable tooling is evenly distributed with several second boss, and described second is convex
Platform is provided with positioning hole corresponding with the alignment pin and through the movable tooling.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement：
Alternatively, it is equipped with reinforcement between two adjacent first boss and between adjacent two second boss
Groove.
Alternatively, the first boss and the second boss are sector.
Alternatively, the quantity of the alignment pin is at least 3.
Alternatively, connected between the alignment pin and the positioning hole by fastener.
Alternatively, the end of the alignment pin is provided with external screw thread, and the fastener is internal thread and the external screw thread phase
The nut matched somebody with somebody.
The beneficial effects of the utility model：
The frock clamp of nylon wheel of the present utility model, using the frock clamp nylon wheel can be ensured in machining clamping
Shi Buneng ensure that the front and rear dimensionally stable uniformity of nylon wheel processing, finally ensure that nylon by radial and axial external force
The dimensional accuracy of wheel.

Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Fig. 1 is assembling explosive view of the frock clamp with nylon wheel 40 of the nylon wheel 40 of the utility model embodiment.Referring to
Fig. 1, the utility model embodiment provide a kind of frock clamp of nylon wheel 40, including：Fixing tool 10 and movable tooling 20,
The fixing tool 10 and the movable tooling 20 are in the form of annular discs, and the inner surface of the fixing tool 10 is evenly distributed with several
First boss 11, the first boss 11 are provided with alignment pin 12, and the inner surface of the movable tooling 20 is evenly distributed with some
Individual second boss 21, the second boss 21 are provided with corresponding with the alignment pin 12 and determined through the movable tooling 20
Position hole 22.
The frock clamp of nylon wheel 40 of the present utility model, it can ensure that nylon wheel 40 is machining using the frock clamp
It can not be ensure that nylon wheel 40 processes front and rear dimensionally stable uniformity by radial and axial external force during clamping, it is final to ensure
The dimensional accuracy of nylon wheel 40.
Referring to Fig. 1, it is equipped between two adjacent first boss 11 and between adjacent two second boss 21
Reinforcement groove 13.Wherein, the first boss 11 and the second boss 21 are sector.The reinforcement groove 13 of fixing tool 10
It is fully mated with the reinforcement 41 of nylon wheel 40 and the face of wheel web.Alignment pin 12 is engaged with positioning hole 22, can make activity
Frock 20 is fixed.
Wherein, the quantity of the alignment pin 12 is at least 3.At least three alignment pin 12 can be to determine fixing tool 10
Unique positions.
Fig. 2 is the side view of frock clamp shown in Fig. 1；Fig. 3 is the sectional view of the A-A along Fig. 2.Referring to Fig. 3, the positioning
Connected between pin 12 and the positioning hole 22 by fastener 30.The end of the alignment pin 12 is provided with external screw thread, the fastening
Part 30 is the nut that internal thread matches with the external screw thread.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
