Detailed Description
The following further describes a specific embodiment of the present invention with reference to the drawings and technical solutions.
As shown in fig. 1 and 2, a lateral pressing mechanism for pressing a part in machining includes a seat assembly 1 and a positioning block 2.
Two positioning blocks 2 are arranged on a special square box of a horizontal machine tool and are arranged at an angle of 90 degrees, the positioning blocks are fixed by cylindrical pins 4 and tightened by screws 3, and after assembly, the verticality of the positioning blocks and the verticality of the positioning blocks are within 0.03 mm.
The movable pressing block 5 is arranged in a groove at the bottom of the support B, one end of the adjustable bolt 6 is in threaded connection with the movable pressing block 5, and the other end of the adjustable bolt is inserted into a round hole at the end part of the support B. The bottom of the support B is provided with a threaded hole, and an internal hexagonal screw A7 is screwed into the threaded hole and matched with an annular notch of the adjustable bolt 6, so that the adjustable bolt 6 can be adjusted after being assembled without stagnation and jamming. And the internal hexagonal screw B9 is arranged in a through hole at the top of the support B and is vertical to the 7-degree wedge-shaped surface of the movable pressing block 5.
And (3) installing the assembled support B into a support A, and connecting and fixing the support A with a special square box of the horizontal machine tool by using a precise internal hexagonal screw C8 according to a proper position. At the moment, the part is attached to a square box special for a horizontal machine tool, the reference surface of the part is in contact with the fringe surfaces of two positioning blocks 2 forming an angle of 90 degrees, and the adjustable bolt 6 is rotated by an inner hexagonal wrench to laterally compress the part. If the lateral pressing surface of the part has a certain angle with the reference surface, the support B can swing left and right in the support A in a small amplitude, and the strip surface at the front end of the movable pressing block 5 is always kept to be completely contacted with the part to-be-pressed surface instead of being in point or line contact. Meanwhile, an inner hexagonal screw B9 on the support B is screwed down, so that the front end of the inner hexagonal screw B9 is in contact with a 7-degree notch of the movable pressing block 5, the movable pressing block is prevented from moving backwards due to insufficient pressing force of the adjustable bolt, and the clamping of parts is guaranteed to be firm. After the parts are machined, the adjustable bolt 6 and the inner hexagonal bolt B9 on the support B are loosened by an inner hexagonal wrench, and the parts are taken down.
If a part with another size is to be replaced for clamping, the position of the support assembly 1 on the special square box can be adjusted. The method is suitable for the part processing range: the length ranges from 750 mm to 110mm, and the width ranges from 650 mm to 30 mm.
