Abstract
The utility model relates to a high-speed grinding machine provided with a damping sleeve, which belongs to the class of electromechanical products. The high-speed grinding machine comprises a front end shell, an inner core, a connecting device, a connecting seat and a motor; the damping sleeve is in a cylindrical shape; one end of the damping sleeve is provided with a stop table; the stop table is provided with a rubber ring; the damping sleeve is arranged over the inner core in a slidable mode and is movably arranged in the front end shell; and the inner core consists of a power shaft sleeve, a front bearing prepressing collar, a front bearing, a back bearing prepressing collar, a back bearing, a setup spring, a power shaft spring, a power shaft and an inner chuck. The damping sleeve is arranged on the inner core of the high-speed grinding machine, which structurally changes the mode that the contact area between the inner core and the front end shell of the prior grinding machine is small. As the damping sleeve can increase the contact area with the front end shell, the phenomenon that manufactured workpieces, assembling error and concentricity are not good because of numerous inner core parts can be eliminated; moreover, the problem about the scale production of products is solved, and the qualification rate of the products is improved.
Description
Technical field
The utility model relates to a kind of high speed sander that shock-absorbing sleeve is housed, and belongs to the electronic product class.
Background technology
At present, along with the generation of science and technology development and various sophisticated products, more and more wide in the use of high speed sander.And this high speed sander is because in process of production, and the parts of its inner core are many, the requirement on machining accuracy height, assembling is complicated, and between the parts interconnect and assembling can produce cumulative errors on the product concentricity.And this cumulative errors are directly brought is exactly the poor quality of product, influences its use.And the requirement on machining accuracy height of this type component, the production qualification rate of product is low, has influenced the batch process of this type component greatly.
Summary of the invention
At above-mentioned existing problems, the purpose of this utility model is to provide a kind of high speed sander that installs shock-absorbing sleeve on the sander inner core additional.
Its technical solution is: a kind of high rotary speed sander that shock-absorbing sleeve is housed, comprise preceding end housing, inner core, jockey, Connection Block and motor, it is cylindric that shock-absorbing sleeve is, one end of shock-absorbing sleeve is provided with only platform, be provided with rubber ring ending the platform place, what shock-absorbing sleeve slided is sleeved on the inner core, and movable being installed in the preceding end housing, inner core is by the power axle sleeve, fore bearing precompressed lasso, fore bearing, rear bearing precompressed lasso, rear bearing, pre-compressed spring, the line shaft spring, line shaft and interior chuck constitute, fore bearing and rear bearing are fixedly mounted on respectively on the outer surface of power axle sleeve, between fore bearing and rear bearing, be set with fore bearing precompressed lasso and rear bearing precompressed lasso, between fore bearing precompressed lasso and rear bearing precompressed lasso, be set with pre-compressed spring, interior chuck, line shaft is movably arranged in the power axle sleeve, between interior chuck and line shaft, be provided with the line shaft spring, be arranged on bayonet lock on the line shaft and be mounted in the draw-in groove that line shaft puts.
Owing to adopt above technical scheme, installed shock-absorbing sleeve additional on the high speed sander inner core of the present utility model, it has changed the little mode of contact area between the sander inner core and preceding end housing in the past from structure.Because shock-absorbing sleeve can increase and preceding end housing between contact area, it can be eliminated because inner core parts making workpiece and rigging error and the bad phenomenons of concentricity that cause more, and has improved the large-scale production problem of product, the qualification rate of raising product.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in the figure
A kind of high rotary speed sander that shock-absorbing sleeve is housed, sander is made up of preceding end housing 1, inner core, shock-absorbing sleeve 2, jockey, Connection Block and motor.Inner core is by power axle sleeve 7, fore bearing precompressed lasso 12, fore bearing 5, rear bearing precompressed lasso 3, rear bearing 8, pre-compressed spring 4, line shaft spring 11, line shaft 10 and interior chuck 6 constitute, fore bearing 5 and rear bearing 8 are fixedly mounted on respectively on the outer surface of power axle sleeve 7, between fore bearing 12 and rear bearing 5, be set with fore bearing precompressed lasso 12 and rear bearing precompressed lasso 3, between fore bearing precompressed lasso 12 and rear bearing precompressed lasso 3, be set with pre-compressed spring 4, interior chuck 6, line shaft 10 is movably arranged in the power axle sleeve 7, between interior chuck 6 and line shaft 10, be provided with line shaft spring 11, be arranged on bayonet lock on the line shaft 10 and be mounted in the draw-in groove on the power axle sleeve 7.Shock-absorbing sleeve 2 is cylindric, and an end of shock-absorbing sleeve 2 is provided with only platform, is provided with rubber ring 9 ending the platform place, and what shock-absorbing sleeve 2 slided is sleeved on the inner core, and before movable being installed in the end housing 1.One end of jockey is installed in the draw-in groove that is arranged on the line shaft 10, and the other end is installed in the rotating shaft of motor, and preceding end housing is rotatably connected with Connection Block, and Connection Block is rotatably coupled on the shell of motor.
Sander of the present utility model can be at the inner core with shock-damping structure and is sleeved on and overcomes, eliminate it under the acting in conjunction of the shock-absorbing sleeve inner core outside because of the bad phenomenon of error concentricity that parts and assembling produce, and can not produce swing in use and shakes.
