Description
Technical field
The utility model belongs to dynamic balance detecting device technical field, specifically cutter dynamic balance testing device.
Background technique
Cutter is the indispensable tool of the processing such as cutting, bore hole in component of machine process.It is dynamic when cutter is run
Balance quality is an important reference indicator of tool sharpening precision, if the dynamic balance performance of cutter is bad, is easy to cause and adds
The Product Precision that work comes out is had a greatly reduced quality.
Existing cutter dynamic balance testing device is usually by Cutting tool installation manner in dynamic poise device, by vibrating sensor and
Photoelectric sensor detects oscillating curve, and measurement can be measured the phase point of rotor unbalance every time, and it is laggard to obtain balance position
Row counterweight.And this kind of dynamic balance testing device is not only at high cost, but also is only for cutter, and when cutter is attached on lathe
Its dynamic balance performance can change, and dynamic put down is also resulted in due to component wear after lathe runs a period of time
Weighing apparatus variation, only individually the dynamic balancing of adjusting cutter can not guarantee dynamic balance performance when cutter is run.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide cutter dynamic balance testing device, this kind of cutter dynamic balancing measurement
Device is used to quickly detect the dynamic balance performance for the cutter being mounted on lathe, and low in cost, and structure is simple, and conveniently
Mobile alignment.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: cutter dynamic balancing is surveyed
Trial assembly is set, including pedestal, is provided on the pedestal and is vertically directed slot, and guide rod, the guiding are provided on the guide groove
Bar upper end is provided with detector, and the first tension spring is provided between the guide rod and the pedestal, is penetrated on the pedestal useful
In the bolt of the fixation guide rod, the base bottom is provided with the sliding slot being connected to the guide groove, slides in the sliding slot
Dynamic to be provided with sliding shoe, the sliding slot two sides are provided with waist hole, and rotation is provided with shaft in the sliding shoe, set in the shaft
It is equipped with runner, there is a centre bore on the detector, the detector is evenly distributed with several guiding along the centre bore
Hole is inserted with detection bar in the pilot hole, the second tension spring, the detection is provided between the detection bar and the detector
Scale mark is provided on bar.When this kind of cutter dynamic balance testing device is not used, for fixing at the bolt of the guide rod
In unscrewing state, guide rod holds out against the sliding shoe by the drop-down of the first tension spring at this time, and idler wheel is rolled on the ground, from
And be moved easily, when detecting, central aperture cutter shaft to be inserted in, detection bar withstands cutter shaft, it is then turned on lathe operating,
Indicate that dynamic balance performance is preferable if shake or fine jitter do not occur for detection bar, if detection bar shake severity indicates dynamic balancing
Degradation.
In above-mentioned technical proposal, it is preferred that the detector includes two semicircular rings, and two described semicircular rings one end turn
Dynamic connection, the two semicircular rings other ends are detachably connected by screw.Enable detector convenient using the structure
It is set in cutter shaft.
In above-mentioned technical proposal, it is preferred that be provided with bearing between the sliding shoe and the shaft.It is used using the structure
Abrasion between reduction sliding shoe and shaft.
The utility model compared with prior art, has the following beneficial effects: that this kind of cutter dynamic balance testing device does not make
Used time, the bolt for fixing the guide rod, which is in, unscrews state, and guide rod holds out against the cunning by the drop-down of the first tension spring at this time
Motion block enables idler wheel to roll on the ground, to be moved easily, when detecting, central aperture cutter shaft is inserted in, inspection
Measuring staff withstands cutter shaft, is then turned on lathe operating, indicates dynamic balance performance if shake or fine jitter do not occur for detection bar
Preferably, indicate that dynamic balance performance is deteriorated if detection bar shake is severe.
