Description
Technical field
The utility model relates to a kind of mechanical mounting device, specifically refers to a kind of axle flat key erecting device.
Background technology
In the driven Design of machinery, often adopt axle flat key to realize, for the flat key of motor-shaft extending end, by installing flat key to realize the transmission of motor power on motor-shaft extending end.And be mostly when installing flat key at present to adopt copper hammer to knock in keyway by flat key, which is adopted to have certain violence nature, knock motor shaft in process and bear larger impulsive force, find that shaft extension is beated overproof, therefore in the urgent need to a kind of stable axle flat key erecting device through normal after installing flat key.
Summary of the invention
For solving technical problem existing in current axle flat key installation process, the utility model provides a kind of axle flat key erecting device.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of axle flat key erecting device, comprise an electric wrench, it is characterized in that: this device also comprises top board and base plate, top board, connected by lead between base plate, slide block is provided with between top board and base plate, lead is through slide block and slide block can be movable along lead, the inside of slide block is provided with the through screwed hole in front and back in the axial direction, one end of threaded rod is positioned at the screwed hole inside of slide block, the other end of threaded rod passes top board and threaded rod can rotate freely, the end passing top board one end at threaded rod is provided with grafting counterbore, described electric wrench is connected with threaded rod by grafting counterbore.
Further, described slide block is convex shape dextrorotation 90 °.
Further, also comprise electric wrench fixed mount, described electric wrench fixed mount comprises fixed head, and the center of this fixed head is provided with electric wrench and stretches into hole, the periphery stretching into hole at electric wrench is provided with the fixing hole fixing with electric wrench, is connected and fixed between fixed head and top board by pull bar.
Further, described base plate is provided with arc groove.
This axle flat key erecting device is rational in infrastructure, easy and simple to handle, can realize the stable combination of flat key and axle, prevents the direct impact to axle in installation process, ensures that flat key installs the distortion of rear axle and beats overproof.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model first embodiment.
Accompanying drawing 2 is the structural representation of the utility model second embodiment.
Accompanying drawing 3 is the structural representation of fixed head.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of axle flat key erecting device, comprise an electric wrench 1, top board 2 and base plate 3, top board 2, connected by lead 4 between base plate 3, slide block 5 is provided with between top board 2 and base plate 3, lead 4 is through slide block 5 and slide block can be movable along lead, screwed hole 6 through before and after being provided with in the axial direction in the inside of slide block 5, one end of threaded rod 7 is positioned at screwed hole 6 inside of slide block, the other end of threaded rod passes top board 2 and threaded rod can rotate freely, the end passing top board one end at threaded rod is provided with grafting counterbore 8, described electric wrench 1 is connected with threaded rod 7 by grafting counterbore 8.
Known by foregoing description, when positive and negative rotation threaded rod 7, by the cooperation of screw thread, threaded rod 7 can be with movable slider 5 to move forward and backward along lead 4.
During use, by installation shaft through the space slide block 5 and base plate 3, base plate 3 props up installation shaft, keyway points to slide block 5, in keyway, place flat key, start electric wrench 1 and drive threaded rod 7 to rotate, promote slide block 5 by the rotation of threaded rod 7 and flat key is exerted a force in press-in keyway stable for flat key to the motion of base plate 3 direction simultaneously, install and rotate backward electric wrench 1 by slide block 5 away from base plate, withdraw from installation shaft.
During actual fabrication, for ensureing the intensity of slide block, as shown in Figure 1, slide block is convex shape dextrorotation 90 °, is provided with arc groove 9 to ensure the accurate location of installation shaft on base plate 3 simultaneously, also can meet the installation needs of different-diameter installation shaft simultaneously.
Embodiment 2
In embodiment 1, electric wrench 1 and the connection of threaded rod 7 under the manual active force held, carry out grafting fix, when operating, due to vibrations when electric wrench rotates, manual the uneven of force is easy to the shakiness causing power transmission, for solving this technical problem, add following devices in the present embodiment.
As shown in Figure 2, in the present embodiment, the basis of embodiment 1 adds electric wrench fixed mount.This electric wrench fixed mount fixed head 10, the center of this fixed head 10 is provided with electric wrench and stretches into hole 101, and the periphery stretching into hole 101 at electric wrench is provided with the fixing hole 102 fixing with electric wrench.By reference to the accompanying drawings shown in 2, hole is stretched into through the electric wrench on fixed head in the front end of electric wrench 1, and is adopted by fixing hole 101 between electric wrench front end surface and fixed head and be screwed.As shown in Figure 2, be connected and fixed by pull bar 11 between fixed head 10 and top board.
After increasing electric wrench fixed mount, in stable connection status between electric wrench 1 and top board 2, can ensure that electric wrench is connected with the stable of threaded rod, ensure the stable conveying of power.
