Embodiment Construction
[0013] Combine below figure 1 , to further illustrate the present invention.
[0014] For simplicity of description, the lower surface of the base refers to the side facing the ground, the upper surface of the base refers to the side opposite to the lower surface of the base, the lower surface of the table refers to the side in contact with the upper surface of the base, and the table The upper surface refers to the side opposite to the lower surface of the platen, the lower surface of the pressing plate refers to the side facing the ground, and the upper surface of the pressing plate refers to the side opposite to the lower surface of the pressing plate.
[0015] Such as figure 1 As shown, an upper end beam centering device includes a base 1 and a pressing plate 2. The upper surface of the base 1 is fixed with several pairs of spring seats 3 distributed on the left and right sides of the upper surface of the base and symmetrically distributed along the centerline of the leng...

The invention discloses an upper end beam centering device which comprises a base (1), a plurality of pairs of spring seats (3) are fixedly connected to the upper surface of the base (1), the spring seats (3) are provided with grooves, springs (4) are arranged in the grooves of the spring seats (3), one ends of the springs (4) are fixedly connected with pressing sleeves (5), and the other ends of the springs (4) are fixedly connected with the grooves of the spring seats (3), a platen (6) is fixedly connected to the center of the upper surface of the base (1), the center line of the platen along the length direction is parallel to the center line of the upper surface of the base (1) along the length direction, the upper surface of the platen (6) is fixedly connected with positioning blocks (7), limit rods (8) are movably connected to two sides of the platen (6) along the width direction, and the upper surface of the platen (6) and the lower surfaces of the spring seats (3) are almost arranged on the same horizontal plane. By the aid of the structure, two ends of an upper end beam to be centered are respectively arranged in the pressing sleeves at two ends during use, the pressing sleeves are pressed into the grooves of the spring seats under the action of pressure, and finally, the upper beam is centered.
Description
technical field [0001] The invention relates to a centering device for an upper end beam, in particular to an upper end beam centering device for a railway vehicle. Background technique [0002] In the prior art, the centering of the workpiece (such as the upper end beam of a railway vehicle) is generally performed by manual measurement and manual marking, which has low efficiency and large errors. Contents of the invention [0003] The purpose of the present invention is to solve the problem of low efficiency and large error in the conventional method of manual measurement and manual scribing for workpiece centering. [0004] The technical scheme adopted in the present invention is: an upper end beam centering device, including a base, and the upper surface of the base is fixed with several pairs of spring seats distributed on the left and right of the upper surface of the base and symmetrically distributed along the center line of the length direction of the upper surfac...
