Abstract
The invention relates to a knocking device. The knocking device comprises a movable shaft, wherein the lower end of the movable shaft is provided with a knocking head; the upper end of the movable shaft is provided with a limiting plate; and a linear bearing is sheathed outside the movable shaft. The knocking device is applicable to knocking materials, and compared with the knocking device used at present, the knocking device provided by the invention has the advantage that the knocking force of the knocking head is increased.
Description
Technical field
The present invention relates to a kind of knocking device that is used to knock material.
Background technology
Thereby knocking device is to be used to knock material to make material internal structure one of common tool more closely.The structure of present employed knocking device comprises fixed head, be provided with porosely in the fixed head, penetrate in the hole and be provided with movable axis, the lower end of movable axis is provided with striking head, movable axis between striking head and the fixed head is provided with spring, and the upper end of movable axis is provided with limiting plate.During use, effect by external force moves up and down movable axis in the hole of fixed head, striking head is knocked material along with moving up and down of movable axis, thereby make the material internal structure more tight, wherein when movable axis moved upward, spring was in contraction state, when movable axis moves downward, spring awards the certain downward active force of striking head, thereby makes the percussion power of striking head bigger.The shortcoming of present employed knocking device is: when moving up and down in the hole of movable axis at fixed head, be sliding friction between the outer wall of movable axis and the fixed head, coefficient of friction is bigger, thereby has reduced the percussion power of striking head.
Summary of the invention
Technical problem to be solved by this invention is: a kind of knocking device that can improve the percussion power of striking head is provided.
For addressing the above problem, the technical solution used in the present invention is: a kind of knocking device, comprise movable axis, and the lower end of movable axis is provided with striking head, and the upper end of movable axis is provided with limiting plate, and the outer cover of described movable axis is provided with linear bearing.
Described movable axis is provided with spring, and spring is on the movable axis between striking head and the linear bearing.
The lower end of described linear bearing is provided with steel plate washer.
The invention has the beneficial effects as follows: above-mentioned knocking device, simple in structure, with low cost.Compare with present employed knocking device, adopt linear bearing to replace fixed head, thereby when movable axis is moved up and down, be rolling friction between movable axis and the linear bearing in linear bearing, coefficient of friction is less, and the percussion power of striking head obtains increasing.
Description of drawings
Fig. 1 is the structural representation of a kind of knocking device of the present invention;
Fig. 2 is the structural representation that movable axis is in the state of moving upward among Fig. 1;
Among the figure: 1, movable axis, 2, striking head, 3, limiting plate, 4, linear bearing, 5, steel plate washer, 6, spring.
The specific embodiment
Below by specific embodiment a kind of knocking device of the present invention is described in further detail.
As shown in Figure 1, a kind of knocking device, comprise movable axis 1, the lower end of movable axis 1 is provided with striking head 2, and the upper end of movable axis 1 is provided with limiting plate 3, and the outer cover of described movable axis 1 is provided with linear bearing 4, the lower end of linear bearing 4 is provided with steel plate washer 5, movable axis 1 between striking head 2 and the linear bearing 4 is provided with spring 6, and wherein limiting plate 3 is used to prevent movable axis 1 when moving downward, and movable axis 1 drops out from linear bearing 4.
Operation principle of the present invention is: during use, the effect by external force moves up and down movable axis 1 in linear bearing 4, and striking head 2 is knocked material along with moving up and down of movable axis 1, thereby makes the material internal structure more tight.As shown in Figure 2, wherein when movable axis 1 moved upward, spring 6 was in contraction state, and when movable axis 1 moved downward, spring 6 awarded the certain downward active force of striking head 2, thereby makes the percussion power of striking head 2 bigger.Compare with present employed knocking device, adopt linear bearing 4 to replace fixed heads, thereby when movable axis 1 is moved up and down, be rolling friction between movable axis 1 and the linear bearing 4 in linear bearing 4, coefficient of friction is less, and the percussion power of striking head 2 obtains increase.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (3)
1. a knocking device comprises movable axis, and the lower end of movable axis is provided with striking head, and the upper end of movable axis is provided with limiting plate, it is characterized in that: the outer cover of described movable axis is provided with linear bearing.
2. a kind of knocking device according to claim 1 is characterized in that: described movable axis is provided with spring, and spring is on the movable axis between striking head and the linear bearing.
