Description
Technical field
The invention belongs to the technical field of Medical Devices, specially a kind of dynamic modification of detector.
Background technology
Problems be present in existing detector：
1), in the process of running, because cylinder pressurizes, it can cause integrally to be not at parastate during compression, produce skew
So as to cause to run abnormal sound.
2), base machining accuracy is inadequate, after long-play, produces more residue, causes running resistance excessive, produces
Larger grating.
3), product backhaul gap is excessive.
The reason for existing it is as follows：
1st, trapezoidal bull ball screw accuracy is inadequate, and product backhaul gap is excessive.
2nd, the design of Japanese prototype is a design well in itself, but without reserved mounting and adjusting function.Institute
It is high with the required precision to the parts such as screw mandrel, linear bearing and workpiece.
3rd, the mechanical component product synthesis precision purchased at present is inadequate, and slide unit is in direction of principal axis energy double swerve.Work as heavy duty
When, slide unit is in non-equilibrium state and causes abnormal sound.
4th, the cylinder in day machine, the exit of cylinder rod is very close to each other, and the cylinder used is requirement have between
Gap, here it is in order to eliminate mechanical structure precision it is inadequate caused by deviation (present mechanical structure uses Japanese prototype cylinder,
Do not push away not come out at all, exactly because precision not enough causes).But existing mechanical component Accumulated deviation is too big, the gap of cylinder rod outlet
The deviation of mechanical structure product can not be made up completely, and (gap in cylinder rod exit can not amplify again, then amplify and can cause cylinder
There is the danger to come off after inner carrier long-term use).
The content of the invention
It is simple in construction it is an object of the invention to provide a kind of dynamic modification of detector, it is easy to use.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of dynamic modification of detector, including mounting base and power part, it is provided with the mounting base and is used for
The installation screw of power part, in addition to leading screw and director element are installed, two screw threads, and side are evenly equipped with the leading screw
On screw thread is provided with arch arc groove, the feed screw nut is made up of polyamide-based resin material, the leading screw rotational installation
In feed screw nut, the director element includes line slideway, sliding block, and the slider bottom is arranged with two row steel balls in parallel, and two
Row steel ball contacts with line slideway, and the power part drives leading screw to rotate.
Further, the power part includes motor and cylinder, and the cylinder promotes sliding block movement.
Further, the screw mandrel is made up of SUS304 materials.
The beneficial effects of the invention are as follows：
It can realize long-term non-maintaining.Workpiece is made using machining center, it is ensured that the precision and uniformity of product.
After adjustable design assembling and setting, product can realize running at high precision.

Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
A kind of dynamic modification of detector, including mounting base 1 and power part, use is provided with the mounting base 1
In the installation screw of installation power part, in addition to leading screw 2 and director element 3, two screw threads are evenly equipped with the leading screw 2, and
And screw thread is provided with arch arc groove on side, the feed screw nut is made up of polyamide-based resin material, 2 turns of the leading screw
Dynamic to be arranged in feed screw nut, the director element 3 includes line slideway 4, sliding block 5, and the bottom of sliding block 5 is arranged with two in parallel
Row steel ball, two row steel balls contact with line slideway 4, and the power part drives leading screw 2 to rotate, and the power part includes motor
And cylinder, the cylinder promote sliding block movement, the screw mandrel is made up of SUS304 materials.
The type selecting and feature of screw mandrel 2
Using the screw mandrel 2 with Japanese prototype machine same brand specification, screw mandrel 2 encircles arc using with ball-screw identical
Groove, 2 screw threads, so as to ensure that axial gap is significantly less than trapezoidal screw, only 0.05mm, and being driven smooth.
Screw mandrel 2 uses SUS304 materials, therefore corrosion resistance is strong.Diameter of axle 8mm helical pitches 8mm both can guarantee that linear velocity, have again
Meet loading moment demand
Feed screw nut is using the good polyamide-based resin material of sliding capability.The material contains lubricant, even if being not added with
Oil can also be used.Producer's test is drawn, without exception (according to product stroke after screw mandrel walking 100KM under without any lubricating condition
85mm is calculated, it is ensured that walking about 1176470 times is without exception, such as daily walking can meet for 500 times 6~7 years it is non-maintaining),
It is long-term non-maintaining so as to realize, lubricant is smeared when such as dispatching from the factory and is used, can make that operation is more smooth and the life-span is longer.
The type selecting and feature of director element 3
Core in this product is exactly the precision being oriented to, and Japanese prototype machine design is remote, guide part in original design
Part selection uses optical axis and linear bearing, but domestic optical axis Product Precision is poor, and hardness is low can not to meet technical requirements (machine originally
Tool is often in not parallel state, and abnormal sound is big.Maximum reason is exactly that guide-localization precision not enough causes).
Guiding parts 3 selects the non-maintaining line slideway 4 of import, relative to the scheme of optical axis+linear bearing, there is high-speed cruising
When the advantages that noise is low, guide rail is wear-resistant, precision is high easily disassembled, load capacity is stronger
The non-maintaining line slideway 4 selected also has following characteristics：
1st, interiors of products self-lubricating part can bear 20, more than 000KM nothing by the usage amount control of lubricating oil at least
Fuel feeding is walked, and realizes the long-term non-maintaining of product, while be also made that very big contribution for earth environment.
2nd, with super compact sliding block 5, two row steel balls and the point-contact junction structure of track four of original creation, the high-precision of stabilization can be obtained
Degree and rigidity, and low noise.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
Spirit and principle within the modifications, equivalent substitutions and improvements made etc., should be included in the claim protection model of the present invention
Within enclosing.
