Abstract
The invention relates to a centrifugal force compensation mechanism used for a power chuck, which comprises a chuck body, sliders and a rear cover. The centrifugal force compensation mechanism is characterized by further comprising compensation blocks and compensation shafts; the compensation blocks are arranged inside the rear cover and the compensation shafts are arranged inside the chuck body; taking the middle point as pivot, one end of each compensation shaft is connected with the corresponding compensation block and the other end of each compensation shaft is connected with the corresponding slider; and the number of the sliders is three, the number of the compensation shafts is three and the number of the compensation blocks is three. The centrifugal force compensation mechanism has a simple, compact and reasonable structure; can effectively compensate the part of the clamping force, which is lost during high-speed rotation of the chuck; and can effectively increase the clamping force during high-speed rotation of the chuck as compared with the common power chuck. Therefore, the centrifugal force compensation mechanism has a broad application prospect in power chucks and the like.
Description
Technical field
The present invention relates to a kind of centrifugal force compensation mechanism, specifically be used for the power chuck that matches with numerically controlled lathe, the clamping force of when chuck rotates at a high speed, recovering damage belongs to the machine tool accessories technical field.
Background technology
In prior art, comparatively close with the present invention is common power chuck.Common power chuck does not have the centrifugal force compensation mechanism, the clamping force that the power chuck of this kind structure can not be recovered damage when chuck rotates at a high speed, and when power chuck rotated at a high speed, clamping force can reduce along with the raising of speed, can't reach the clamping force requirement.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of centrifugal force compensation mechanism that is used for power chuck is provided, this compensation mechanism can effectively improve the clamping force of chuck when rotating at a high speed.
According to technical scheme provided by the invention, be used for the centrifugal force compensation mechanism of power chuck, comprise chuck body, slide, bonnet; Characteristic is: also comprise compensation block and compensating shaft; Compensation block is installed in the said bonnet, and compensating shaft is installed in the chuck body, is fulcrum with the centre; Compensating shaft one end is connected with compensation block, and the other end is connected with slide.
Said slide is three; Said compensating shaft is three; Said compensation block is three.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; The clamping force of loss is compared with common power chuck in the time of effectively compensating chuck and rotate at a high speed, can effectively improve the clamping force of chuck when rotating at a high speed, therefore, on equipment such as power chuck, has broad application prospects.
Description of drawings
Fig. 1 uses volt attitude figure for the present invention in power chuck.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise chuck body 1, three slides 2, bonnet 3, three compensation blocks 4, three compensating shafts 5 etc.
The present invention installs 4, three compensating shafts 5 of three compensation blocks and is installed in respectively in the chuck body 1 in bonnet 3, three compensation blocks 4 connect with three slides 2 through three compensating shafts 5 respectively.
When chuck rotated at a high speed, the centrifugal force of compensation block acted on the slide through compensating shaft, offset the centrifugal force of slide, reached the purpose of compensation clamping force.
Operation principle of the present invention:
When the present invention rotated at a high speed when chuck, the claw of power chuck and slide can receive outside action of centrifugal force, and clamping force is reduced.This moment, compensation block received the leverage of outside action of centrifugal force through compensating shaft simultaneously, cancelled out each other with the centrifugal force that slide receives, and reached the effect of compensation clamping force.
