The adjusting mechanism including set up in dovetail 11 on the supporting baseplate 1, well kickoff 7 the bottom seted up with dovetail 11 matched with dovetail, dovetail 11's both ends top all is provided with fixed block 12, two horizontal rotation is provided with the regulation pole 13 between the fixed block 12, adjust pole 13 and pass well kickoff 7 and with well kickoff 7 threaded connection.
One end of the adjusting rod 13 is provided with a driving wheel 14, and the fixing block 12 is located between the driving wheel 14 and the first limiting body 8. A driving handle 15 is rotatably arranged between the edge of the driving wheel 14 and the driving wheel 14, and the driving wheel 14 is positioned between the driving handle 15 and the fixed block 12.
The cross section of each side supporting block 6 is arc-shaped, and the circle centers of the cross sections of the two side supporting blocks 6 are located between the two side supporting blocks 6. The cross section of the limiting block 10 is arc-shaped, and the circle center of the cross section of the limiting block 10 is located between the two side supporting blocks 6.
A first limit screw 16 is arranged through the first limit body 8 and in threaded connection with the first limit body 8. And second limiting screw rods 17 penetrate through two sides of the second limiting body 9 and are in threaded connection with two sides of the second limiting body 9.
When the clamp assembly for the automobile brake shoe is used for reaming and processing the brake shoe 21, firstly, the middle support block 7 is adjusted to a distance (such as 1cm retreating) slightly far away from the first limiting body 8 and the second limiting body 9 through the adjusting mechanism, then the panel 19 is horizontally placed on the two side support blocks 6 and the middle support block 7, the arc-shaped panel 19 is supported by the side support blocks 6 and the middle support block 7 and can be stably placed, then the panel 19 is moved, the sleeve 20 is abutted into the second limiting body 9, one end of the rib plate 18 is abutted onto the first limiting body 8, at the moment, the outer wall of the end part of the rib plate 18 is abutted onto the first limiting screw 16, and the outer wall of the sleeve 20 is abutted onto the two second limiting screws 17; then, the position of the middle supporting block 7 is adjusted through the adjusting mechanism, and the limiting block 10 is abutted to the panel 19, so that the position of the panel 19 in the horizontal direction is stably maintained, at the moment, a worker can remove the hand from the panel 19, then the lifting cylinder 2 lowers the pressing plate 3 and presses the top of the panel 19, and thus the fixing of the position of the panel 19 is completed. The boring bar and the drill rod above the pressing plate 3 can be lowered after the position of the panel 19 is fixed, and the end parts of the sleeve 20 and the rib plate 18 are reamed and punched through the second machining hole 5 and the first machining hole 4 respectively.
Furthermore, when a worker directly presses the panel 19 by hand and waits for the pressing plate 3 to descend, the panel 19 is usually provided with oil and the like, and has certain viscosity, so that even though the C-shaped panel 19 can be stably placed in the structure which is conventionally used at present, the panel 19 may be brought down by the hand of the worker, and therefore, the worker needs to tightly hold the panel 19 by hand in the actual processing process. However, in the structure of the embodiment, since the worker's hand has moved away from the panel 19 during the lowering of the platen 3, the worker's hand can be prevented from being pinched by the platen 3 and the top of the panel 19, and the processing safety is improved.
The clamp assembly of the embodiment may be used when the boring bar and the drill rod are arranged on the same equipment, or when the clamp assembly fixes the panel 19, the fixture assembly is moved and then respectively processed by conventional equipment of a boring machine and a drilling machine; that is, the manner of using the clamp assembly is not within the limitation of the present embodiment, and if the use case is that the boring bar and the drill rod are simultaneously lowered for processing, the apparatus can be understood and realized by the conventional technical means by those skilled in the art, and therefore, the detailed description thereof is omitted.
After the panel 19 is placed on the side supporting blocks 6, the middle supporting block 7 can also support the bottom of the panel 19, and the two side supporting blocks 6 are both in the shape of a circular arc similar to the panel 19, so that the supporting stability of the panel 19 can be improved, and the position stability of the panel 19 is further improved. When the position of the middle supporting block 7 is adjusted, only the adjusting rod 13 needs to be rotated, the adjusting rod 13 is rotatably connected with the two fixed blocks 12, so that the position of the adjusting rod 13 is fixed, and meanwhile, the adjusting rod 13 is in threaded connection with the middle supporting block 7, so that the position of the middle supporting block 7 can be changed by rotating the adjusting rod 13; the dovetail groove at the bottom of the middle supporting block 7 is limited by the dovetail body 11, so that the movement stability of the middle supporting block 7 is further improved. When the adjusting lever 13 is rotated by the driving handle 15 and the driving wheel 14, not only the driving force is reduced, but also the sliding friction between the worker's hand and the driving wheel 14 can be prevented since the driving handle 15 is rotatably connected to the driving wheel 14.
The limiting block 10 is also arc-shaped, so that after the limiting block 10 collides with the arc-shaped panel 19, the limiting block 10 can also limit the panel 19 in the directions of two sides, and the position stability of the panel 19 is further improved. Along with the increase of live time, the tip of first stop screw 16 and second stop screw 17 all can receive the wearing and tearing of different degrees, just can rotate first stop screw 16 and second stop screw 17 this moment to the length that first stop screw 16 passed first spacing body 8, and the length that second stop screw 17 passed second spacing body 9 is adjusted, then still can be accurate restrict panel 19's position, guaranteed processingquality.
In another embodiment, the position of the first and second spacing bodies 8, 9 may also be adjustable, so that non-sized brake shoes or other sized workpieces may be clamped.
It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
