Abstract
The utility model relates to a device capable of automatically eliminating bounding force, which comprises an upper connecting seat, a lower connecting seat and the like, wherein the upper connecting seat is fixedly mounted with a main body, the center of the main body is opened with a through hole, and the width of a through hole which is connected with the upper connecting seat is bigger than the width of a through hole on the lower end to form a step, and slide blocks are mounted on the step. The two slide blocks are respectively arranged on two sides of the through hole, the outer lateral sides of the slide blocks are vertically opened with round holes without through holes, springs are arranged in the round holes, and the springs are pressed between the bottoms of the round holes and the inner wall of the main body, the lower ends of the lateral sides in the middle of the slide blocks are outwards inclined, and a ladder shape whose upper portion is small and lower portion is big is formed in the space between the two slide blocks, and the ladder-shaped lower connecting seat is mounted between the two slide blocks, a strip-shaped hole is opened on the lower connecting seat, a connecting pin penetrates through the strip-shaped hole, and is fixed on the main body, the lower end of the lower connecting seat is equipped with a guide sleeve which is matched with the inner wall of the main body in a sliding way. Since the rebounding force which is generated is counteracted by the displacements of the springs and the lower connecting seat, thereby automatically and effectively eliminating the rebounding force which is generated.
Description
Technical field
The utility model relates to a kind of automatic elimination rebounding force device.
Background technique
Owing to principle of inertia, the power that has a rebound is unavoidable in the mechanical engineering.But development along with technology, requirement for precision is also more and more higher, and rebounding force will certainly influence a series of technical requirementss such as the displacement of mechanical body and shock resistance, makes machining accuracy receive influence, therefore eliminate rebounding force and also be much accounted of gradually, but also do not have method or device preferably at present.
The model utility content
Be to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple in structure, the automatic elimination rebounding force device that can eliminate rebounding force effectively.
For solving the problems of the technologies described above, the utility model is to realize by following technological scheme:
A kind of automatic elimination rebounding force device is characterized in that comprising upper connecting base, slide blocks, connecting pin, lower connecting base, guide pin bushing, body; Upper connecting base and body are fixedly installed togather, and have through hole in the middle of the described body, with the through hole width of the upper connecting base attachment portion through hole width greater than the lower end, form step, and slide blocks is installed on step; Described slide blocks is two, be located at the both sides of through hole respectively, vertically have the circular hole of blind hole, in circular hole, be provided with spring in the outer side of slide blocks, one end of spring withstands on the bottom of circular hole, one end withstands on the inner body wall, and the side lower end in the middle of the slide blocks is outward-dipping, and the space in the middle of two slide blockss forms up-small and down-big trapezoidal, trapezoidal lower connecting base is installed between two slide blockss, have bar hole on lower connecting base, connecting pin passes from bar hole, is fixed on the body; Lower end at lower connecting base is equipped with guide pin bushing, and the inwall of guide pin bushing and body is slidingly matched.
Aforesaid automatic elimination rebounding force device is characterized in that: between described slide blocks and body block rubber is arranged.
The device of automatic elimination rebounding force of the present utility model owing to the rebounding force that produces is offset by the spring of device and the displacement of lower connecting base, thereby has been eliminated the rebounding force that is produced automatically, effectively.
Description of drawings
Fig. 1 is the structural representation of automatic elimination rebounding force device of the present utility model;
Fig. 2 is the side view of automatic elimination rebounding force device of the present utility model;
Embodiment
As shown in Figure 1, the utility model is eliminated the rebounding force device automatically, comprise upper connecting base 1, slide blocks 5, connecting pin 6, lower connecting base 7, guide pin bushing 8, body 3 etc., upper connecting base 1 is fixedly installed togather with body 3, have through hole in the middle of the body 3, be greater than the through hole width of lower end with the through hole width of upper connecting base 1 attachment portion, form step, slide blocks 5 is installed on step.Slide blocks 5 is two, be located at the both sides of through hole respectively, vertically have the circular hole of blind hole in the outer side of slide blocks 5, in circular hole, be provided with spring 4, one end of spring 4 withstands on the bottom of circular hole, one end withstands on body 3 inwalls, side lower end in the middle of the slide blocks 5 is outward-dipping, spaces in the middle of two slide blockss 5 form up-small and down-big trapezoidal, trapezoidal lower connecting base 7 is installed between two slide blockss 5, have bar hole on lower connecting base 7, connecting pin 6 passes from bar hole, is fixed on the body 3; In the lower end of lower connecting base 7 guide pin bushing 8 is installed, guide pin bushing 8 is slidingly matched with the inwall of body 3.Between slide blocks 5 and body 3, be provided with block rubber 2.
Upper connecting base 1 connects power source (as cylinder etc.), lower connecting base 7 connects performance elements (as anchor clamps etc., be connected with test specimen), because lower connecting base 7 connects with executive component, it is static that executive component keeps when not being subjected to external force, lower connecting base 7 also keeps static like this, when power source drive upper connecting base 1 moves downward, upper connecting base 1, body 3 drives slide blocks 5 together and moves downward, because lower connecting base 7 is motionless, slide blocks 5 can only slide to both sides like this, until slide blocks 5 contacts with block rubber 2 and block rubber 2 can not recompress the time, just can not slide again, that is to say between slide blocks 5 and the lower connecting base 7 and no longer include slide relative, if at this moment upper connecting base 1 continues to move downward, will drive lower connecting bases 7 by slide blocks 5 and move downward, move downward to test specimen and apply strength thereby drive executive component.When power source drive upper connecting base 1 moves upward, upper connecting base 1 and body 3 drive slide blocks 5 together and move upward, the certain distance because connecting pin 6 can slide in lower connecting base 7, because of lower connecting base 7 can not move, also just can not drive executive component and move upward, the strength that also just is not applied on the test specimen.When upper connecting base 1 moved upward, spring 4 drove slide blocks 5 and slides, and contacts with lower connecting base 7, realizes reset function, can eliminate rebounding force automatically in this process, prevents to influence workpiece processing simultaneously.
The foregoing description does not limit the utility model in any form, and all technological schemes that mode obtained of taking to be equal to replacement or equivalent transformation all drop in the protection domain of the present utility model.
