Description
Technical field
The utility model belongs to the measuring instrument field of straightness.
Background technology
Axle is support rotary part and turned round therewith to transmit motion, moment of torsion or the conventional machinery part of moment of flexure.One
As for, major axis refers to axle of the length more than 2 meters.And the length of axle is longer, its difficulty of processing is also bigger, and straightness is also got over
It is unmanageable.Existing major axis straightness measurement apparatus is generally all that cost is high, complex operation using expensive optical instrument,
It is not appropriate for medium-sized and small enterprises.
Utility model content
The purpose of this utility model is the major axis straightness measurement apparatus for providing a kind of low cost.
In order to achieve the above object, base case of the present utility model provides a kind of major axis straightness measurement apparatus, including
Base, mounting bracket, detection unit and the taper sheath being detachably mounted on major axis, the mounting bracket and base are consolidated by bolt
Fixed, the mounting bracket is provided with Limit Bearing, and detect tank is provided with the base, and the detection unit is arranged on the bottom of detect tank
Portion, the detection unit includes indicator lamp, tumbler, elastic component, triggering block and the controlling switch for controlling indicator lamp, described
Tumbler is rotatably connected on the bottom of detect tank, and one end of the elastic component is connected on tumbler, and the other end is connected to triggering
On block, the controlling switch is arranged on the surrounding of triggering block, and the taper sheath is connected with tumbler spline.
The principle of this base case is：First, taper sheath is first set in one end of major axis to be measured, and fix tightly
Gu.Then major axis is passed through into Limit Bearing, and inserted in detect tank, until can not continue to move down.Major axis is rotated afterwards, such as
The comparison of fruit major axis is straight, then may be such that taper sheath is fully mated with tumbler, so as to drive tumbler to rotate；Now, from
In the presence of mental and physical efforts, triggering block overcomes the elastic force of elastic component, is contacted with controlling switch, triggers controlling switch so that indicator lamp point
It is bright., whereas if the straightness of major axis is not high, it indicates that lamp will not be lighted.
The beneficial effect of this base case is：Compared with the optical instrumentation of traditional high cost, this programme with
Conventional mechanically and electrically part, in the market can be bought everywhere, low cost.Meanwhile the straightness of major axis is shown by indicator lamp,
It is very visual and clear, it is easy to operate.
Scheme two：Scheme is preferred based on this, and the elastic component is plastics stage clip.Plastics stage clip has good insulation
Property, it is effectively increased the security of this equipment.
Scheme three：Scheme is preferred based on this, and the indicator lamp is LED.LED is readily available, and energy consumption is low, cost
It is low.
Scheme four：This is preferred for scheme three, the quantity of the indicator lamp be it is multiple, it is parallel with one another between indicator lamp.It is more
The setting of individual indicator lamp, effectively avoid because the damage of indicator lamp in itself causes testing result is inaccurate to ask in addition
Topic.
Scheme five：Scheme is preferred based on this, and the quantity of the detection unit is multiple, and is circumferentially set along tumbler
Put.Multiple detection units are circumferentially disposed, are effectively guaranteed the balance of tumbler, avoid tumbler from offseting.
Brief description of the drawings
Fig. 1 is a kind of structural representation of major axis straightness measurement apparatus of the utility model embodiment.
Fig. 2 is the structural representation of detection unit in Fig. 1.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：Base 10, mounting bracket 20, Limit Bearing 21, taper sheath 30, detection are single
Member 40, tumbler 401, elastic component 402, elastic component 403, controlling switch 404, indicator lamp 50, bolt 60.
As shown in figure 1, a kind of major axis straightness measurement apparatus, including base 10, mounting bracket 20, detection unit 40 and removable
The taper sheath 30 being fixed on major axis unloaded.Mounting bracket 20 and base 10 are fixed by bolt 60, and mounting bracket 20 is provided with spacing
Bearing 21.Detect tank is provided with base 10, detect tank is in inverted T-shaped.
Detection unit 40 is arranged on the bottom of detect tank, as shown in Fig. 2 detection unit 40 includes indicator lamp 50, tumbler
401st, elastic component 403402, triggering block and the controlling switch 404 for controlling indicator lamp 50.Elastic component 403402 uses plastics pressure
Spring is made, good insulation preformance, safe.Tumbler 401 is rotatably connected on the bottom of detect tank, one end of elastic component 403402
It is connected on tumbler 401, the other end is connected in triggering block.The quantity of elastic component 403402 and triggering block is multiple, edge
It is axially arranged tumbler 401.Controlling switch 404 is arranged on the surrounding of triggering block, taper sheath 30 and the spline of tumbler 401
Connection.Spline connection in this programme, as shown in Fig. 2 the lower section of taper sheath 30 is provided with a square block, and on tumbler 401
