Detailed Description

As shown in fig. 1 to 3, the utility model discloses a key clamping tool, which comprises a pushing mechanism 400, a base 100, and a positioning column 200 and a pressing mechanism 300 fixed on the base 100 by bolts, wherein the damaged parts can be replaced or different parts can be replaced by the bolts to adapt to keys 500 with different specifications.

The positioning post 200 is adapted to mate with the key tube 510, and the positioning post 200 is insertable into the interior of the key tube 510 to effect a first repositioning of the key 500. In order to prevent the key 500 from being difficult to be pulled out due to air isolation caused by a sealed space formed after the positioning column 200 is inserted into the key tube 510, a vent groove 210 is formed in the side wall of the positioning column 200 along the length direction, so that the inside and the outside of the key tube 510 are always in an air conduction state, and the key 500 can be easily separated from the positioning column 200.

The pressing mechanism 300 includes a guide holder 310, a push rod 320, and a collet 330, wherein a guide hole is formed on the guide holder 310 to match with the push rod 320, and the push rod 320 can slide in the guide hole. The moving track of the push rod 320 can be ensured to be always straight through the guiding of the guide hole. A baffle 321 is disposed at one end of the push rod 320 far away from the positioning column 200, and the other end of the push rod 320 is connected to the chuck 330. Two springs 322 are arranged between the baffle 321 and the guide seat 310, accommodating holes for accommodating the two springs 322 are arranged on the guide seat 310, and the two springs 322 are respectively abutted against two ends of the baffle 321.

The pushing mechanism 400 includes a driving element 410 and a pushing block 420, wherein the driving element 410 includes a fixed portion fixed to the base 100 and a movable portion capable of moving linearly, and the movable portion is connected to the pushing block 420. The fixed part is fixed at the upper end of the pressing mechanism 300, and the movable part moves in the vertical direction. In the present case, the driving element 410 is an electric cylinder, which is convenient for automatic control, and the electric cylinder has the advantages of quick action, constant stroke and convenient control. The push block 420 is provided with an inclined surface 421, the push rod 320 or the clamp 330 is provided with a slope 323 parallel to the inclined surface 421, the driving element 410 drives the push block 420 to move up and down, and the push block 420 is matched with the slope 323 and the guide seat 310 to push the push rod 320. Because the stress direction of the key 500 during processing is horizontal, the action direction of the driving element 410 is vertical, and the guide seat 310 is used as the support of the push block 420, the influence of the stress of the key 500 during processing on the driving element 410 is small, the driving element 410 is not easy to damage, and the service life is longer.

The upper end of the chuck 330 is provided with a positioning groove 331, the positioning groove 331 is matched with the key handle 520 to realize the second repositioning, and the key 500 is fixed through the dual positioning. The key 500 is positioned and installed through the positioning column 200 and the positioning groove 331, and the key is very convenient and fast. In addition, in order to allow the key lever 520 to be more conveniently inserted into the positioning groove 331, a chamfer or a fillet is provided at a notch position of the positioning groove 331.

The lower end of the clamping head 330 is provided with a pressing groove 332, the bottom of the pressing groove 332 is an arc surface and is matched with the outer wall of the key tube 510, the pushing rod 320 drives the clamping head 330 to move towards the direction close to the positioning column 200 under the pushing of the pushing mechanism 400, and when the action of the driving element 410 is limited, the pressing groove 332 is matched with the positioning column 200 to clamp the tube wall of the key tube 510 from outside to inside, so that the function of fixing the key 500 is achieved. When it is desired to remove the key 500, the movable portion of the driving element 410 moves upward, and the push rod 320 loses its pushing force and returns to its original position under the action of the spring 322.

In order to ensure that the key 500 can be better stressed without deformation during processing, the arc length of the arc surface of the groove bottom of the pressing groove 332 needs to be greater than or equal to one-sixth of a circle and smaller than one-half of a circle, so that the pressing groove 332 can effectively support the key tube 510. In addition, at the limit of the action of the driving element 410, the groove bottom of the positioning groove 331 should also effectively contact the key lever 520 for support.

The above description is only an embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
