Abstract
An automatic height-adjustable calibration castor comprises a pin shaft. The pin shaft is fixedly connected with a plate-shaped part, the lower end of the pin shaft is connected with an idler wheel support, a thrust ball bearing is positioned between the plate-shaped part and the idler wheel support, idler wheels are arranged on the idler wheel support through rotary shafts, and a piece-shaped elastic body is arranged between the plate-shaped part and the idler wheel support. By means of the piece-shaped elastic body arranged on the pin shaft, the automatic height-adjustable calibration castor can automatically adjust height by being compressed, so that leveling between all castors can be achieved. The automatic height-adjustable calibration castor is convenient to install, needn't change a structure greatly, and is suitable for various middle and larger vertical pianos. If two castors under a resonance disk are the castors, a detection process can be eliminated to improve operation efficiency. Silica gel is low in cost and easy to punch, shape and process. Thus, the automatic height-adjustable calibration castor is low in processing cost and convenient to assemble.
Description
Technical field
The utility model relates to a kind of castor, and is especially a kind of when being used for a plurality of castor load-bearing, but the correction castor of automatically regulating height.
Background technology
Because piano is a kind of higher musical instrument object of wooden pieces proportion that contains, wood materials to the sensivity of environment cause processed, cover with paint, lacquer, colour wash, etc., be difficult to when putting by quantitatively control, add that assembly error makes the piano castor flatness error after the assembling excessive.The excessive stability that directly causes piano to be placed of flatness error adds that the piano volume is big, Heavy Weight, and poor stability causes certain potential safety hazard.The defective workmanship of piano parts makes the flatness error of the assembled rear truckle of piano quantitatively not control, through data statistics; The castor out-of-flat all between 0-6mm, with the correction thinking analysis of routine, regulate castor and solve by then available screw-type; If use this type castor; Big, the Heavy Weight reason of invar qin volume, it is extremely inconvenient to regulate timing, and threaded adjustable type cardan wheel structure extremely difficulty design and produce.
Summary of the invention
But the utility model technical matters to be solved provides a kind of correction castor of automatically regulating height, can be adaptive the adjustment height, to overcome situation uneven between the castor.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: but a kind of correction castor of automatically regulating height comprises bearing pin, and bearing pin is captiveed joint with panel-like member; The bearing pin lower end is connected with rolling wheel support; Be provided with thrust ball bearing between panel-like member and the rolling wheel support, roller is installed on the rolling wheel support through rotating shaft, between panel-like member and rolling wheel support, also is provided with the sheet elastic body.
Described sheet elastic body is installed in the flange cover, and the open end of flange cover is equipped with flange shaft sleeve.
Described flange shaft sleeve has the stage of an extension, thrust ball bearing cylindrical and rolling wheel support endoporus interference fit, the cylindrical interference fit of thrust ball bearing endoporus and flange shaft sleeve stage, flange shaft sleeve endoporus and bearing pin free-running fit.
Described sheet elastic body is sheet rubber or silica gel sheet.
But the correction castor of a kind of automatically regulating height that the utility model provides through the sheet elastic body that on bearing pin, is provided with, can be realized the automatically regulating height through compression, thereby realize the leveling between each castor behind pressurized.The utility model simple installation need not to carry out big changing of design, be applicable to various in, the large-scale vertical piano uses, if allow below two castors all adopt this castor, then can remove and detect operation to improve operating efficiency.The silica gel cost that adopts is low, is easy to punch forming processing, and tooling cost is low, and is easy to assembly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Among the figure: bearing pin 1, panel-like member 2, flange cover 3, sheet elastic body 4, axle sleeve 5, roller 6, rotating shaft 7, pad 8, thrust ball bearing 9, rolling wheel support 10.
The specific embodiment
In Fig. 1, Fig. 2, but a kind of correction castor of automatically regulating height comprises bearing pin 1; Bearing pin 1 is captiveed joint with panel-like member 2; Bearing pin 1 lower end is connected with rolling wheel support 10, and bearing pin 1 lower end is provided with thrust ball bearing 9 through pad 8 axial limitings between panel-like member 2 and rolling wheel support 10 supports; Roller 6 is installed on the rolling wheel support 10 through rotating shaft, between panel-like member 2 and rolling wheel support 10 supports, is provided with sheet elastic body 4.Described sheet elastic body 4 is sheet rubber or silica gel sheet, preferably adopts the silica gel sheet.By stretching of sheet elastic body 4, thereby the utility model can be realized adjustment height automatically.
Described sheet elastic body 4 is installed in the flange cover 3, and the open end of flange cover 3 is equipped with flange shaft sleeve 5.The flange cover 3 that is provided with helps limiting the radial deformation of sheet elastic body 4, helps prolonging the service life of sheet elastic body 4.The axle sleeve 5 that is provided with can be guaranteed reliable contact the with sheet elastic body 4 end faces, and helps bearing pin 1 is carried out radial location.
Need to prove that in Fig. 1,2, sheet elastic body 4 is installed in thrust ball bearing 9 tops, still, the below that sheet elastic body 4 is installed in thrust ball bearing 9 also is feasible.
Described axle sleeve 5 has the stage of an extension, thrust ball bearing 9 cylindricals and rolling wheel support 10 endoporus interference fit, the cylindrical interference fit of thrust ball bearing 9 endoporus and axle sleeve 5 stages, axle sleeve 5 endoporus and bearing pin 1 free-running fit.
Come the utility model is described with the installation instance that is used for the piano bottom at present.
Before the utility model is installed, earlier castor is carried out planeness and detect, detect the uneven caster wheel in allow below, the not Self-levelling castor that detects is replaced by the utility model.During installation, bearing pin is put in the bottom outlet on the qin pin, hole and bearing pin are free-running fit, and be with cross recessed countersunk head tapping screw that panel-like member 2 and qin pin is fastening, the firm non-loosening of the utility model after fastening, and mounting means is more convenient.The weight of a piano is about about 300kg, and center of gravity is positioned at the allow rear, and allow part weight is about 200kg, is assigned to two castors, and a castor bears weight and is about 100kg.The utility model caster wheel receives the allow action of gravity; Make the silica gel sheet in the flange cover be compressed, the amount of compression size is by three other castor decisions, and the utility model can be corrected to the optional position in the setting range automatically; Thereby be positioned at same plane with other castor, accomplish from dynamic correction.Recoverable stroke in this example is 6mm, and according to the thickness of different silica gel sheets, the recoverable stroke also can be different.Because of silica gel can be compressed and intensity high, toughness is strong, aseismicity, moisture resistance are strong, so not only automatically calibrating but also arranged long service life of the utility model.
