Abstract
The utility model relates to a knocking device, which comprises a movable shaft. A knocking head is disposed at the lower end of the movable shaft, a limit plate is arranged at the upper end of the movable shaft, and a linear bearing is sleeved o the outer portion of the movable shaft. The knocking device is suitable for knocking materials, and knocking force of the knocking device is larger than that of an existing knocking device.
Description
Technical field
The utility model 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, the effect through external force moves up and down movable axis in the hole of fixed head, and 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.
The utility model content
The utility model technical problem to be solved is: a kind of knocking device that can improve the percussion power of striking head is provided.
For addressing the above problem, the technical scheme that the utility model adopts 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 beneficial effect of the utility model is: above-mentioned knocking device, and 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 utility model;
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
Through specific embodiment a kind of knocking device of the utility model is done further to describe in detail below.
As shown in Figure 1, a kind of knocking device comprises 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.
The operation principle of the utility model is: during use, the effect through 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 utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
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.
