Abstract
The invention relates to a power chuck with a centrifugal force compensation effect, which comprises a chuck body, wherein three grooves are formed at the front end of the chuck body, three sliders are arranged inside the three grooves respectively, three claws are fixed on the three sliders through bolts and three T-shaped blocks, a wedge-catch system is arranged inside the chuck body, the wedge-catch system can slide left and right inside the chuck body, and a stopper cover is fixed to the chuck body. The invention is characterized in that the power chuck further comprises three compensation shafts and three compensation blocks, the three compensation shafts are arranged inside the chuck body respectively, the three compensation blocks are arranged inside a rear cover, the three compensation blocks are connected with the three sliders through the three compensation shafts respectively, oblique slots are formed at the front end of the wedge-catch system and at the positions in the contact with the three sliders, and the front-back sliding motion of the wedge-catch system can be converted into radial motion of the claws. The power chuck can achieve the automatic clamping effect and achieve automatic operation, can effectively compensate the part of the clamping force, which is lost during high-speed rotation of the chuck, and has broad application prospect in numerically-controlled lathes, machining centers and the like.
Description
Technical field
The present invention relates to a kind of centrifugal force compensation power chuck, specifically be used for matching 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.Power chuck comprises that chuck body, bonnet, wedge-catch system, three claws, three T type pieces, said chuck body front ends offer three grooves; Article three, three slides are installed respectively in the groove; On three slides, fix through three T type pieces and three claws with the claw mounting screw; Wedge-catch system is installed in the chuck body, and wedge-catch system can horizontally slip in chuck body.The clamping force that the power chuck of this kind structure can not be recovered damage when chuck rotates at a high speed, when power chuck rotated at a high speed, clamping force can reduce along with the raising of speed, can't reach requirement.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of centrifugal force compensation power chuck is provided, this chuck can be realized clamping automatically, realization automated job, the clamping force of losing in the time of effectively compensating chuck and rotate at a high speed.
According to technical scheme provided by the invention; Centrifugal force compensation power chuck comprises chuck body, wedge-catch system, door, three slides, three T type pieces, three claws; Said chuck body front end offers three grooves, and three slides are installed respectively in three grooves, on three slides, fixes through three T type pieces and three claws with screw; Wedge-catch system is installed in the chuck body; Wedge-catch system can horizontally slip in chuck body, and door and chuck body are fixed, and characteristic is: also comprise three compensating shafts, three compensation blocks; Said three compensating shafts are installed in respectively in the chuck body, and three compensation blocks are installed in the bonnet, and three compensation blocks connect respectively with three slides through three compensating shafts 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.
Said wedge-catch system front end and three slide contact positions are provided with skewed slot, and sliding in the front and back of wedge-catch system to convert moving radially of claw to.
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 in the time of effectively compensating chuck and rotate at a high speed; Machine tool chief axis is realized clamping automatically with common manual chuck specific energy, realizes automated job; Compare with common power chuck; Can effectively improve the clamping force of power chuck when rotating at a high speed, therefore, on equipment such as numerically controlled lathe, machining center, have broad application prospects.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cross section view of Fig. 1.
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, wedge-catch system 2, door 3, three slides 4, three T type pieces 5, bonnet 6, three compensation blocks 7, three compensating shafts 8, three claws 9 etc.
The present invention earlier forms chuck main bodies with chuck body 1, wedge-catch system 2, three slides 4, bonnets 6, and chuck main body is contained in spindle head machine through flange.Offer three grooves at chuck body 1 front end; Article three, three slides 4 are installed in the groove, and fixing through three T type pieces 5 and three claws 9 with screw on three slides 4, wedge-catch system 2 is installed in the chuck body 1; Wedge-catch system 2 can horizontally slip in chuck body 1; Door 3 is fixing with chuck body 1, and wedge-catch system 2 front ends and three slide 4 contact positions are provided with skewed slot, and sliding in the front and back of wedge-catch system 2 to convert moving radially of claw 9 to.Said three compensating shafts 8 are installed in respectively in the chuck body 1,7, three compensation blocks 7 of three compensation blocks are installed respectively in the bonnet 6 are connected respectively with three slides 4 through three compensating shafts 8 respectively.
Operation principle of the present invention:
Centrifugal force compensation power chuck of the present invention is contained in spindle nose with chuck body, is connected with the lathe oil cylinder, matches with numerically controlled lathe.The oil cylinder post-tensioning drives wedge-catch system and moves backward, through the skewed slot on the wedge-catch system slide is produced together with claw again and clamps motion.When chuck rotated at a high speed, claw 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.
