Slider type floating bearing device

Abstract

The invention discloses a sliding block type floating supporting device and belongs to the field of devices for correcting and positioning a horizontal datum plane in the passenger train bogie manufacturing process. The sliding block type floating supporting device comprises a supporting base (1), an adjusting bolt (2), a right siding block (3), an upper supporting seat (4), two connecting rods (6), two side plates (7) and a left sliding block (8). According to the sliding block type floating supporting device, the adjusting bolt and the sliding blocks are comprehensively utilized to change the force transmission direction, and troublesome operation carried out on a spiral tip in a narrow space below a workpiece is changed into convenient and fast operation carried out in a wide space on one side of the workpiece. When used on machine tool platforms such as a ruling machine or a press machine to carry out horizontal correction and positioning on the datum plane of a framework to be machined, the sliding block type floating supporting device is broad in operation visual field and high in positioning accuracy, improves work efficiency and eliminates potential safety hazards.

Description

technical field [0001] The invention belongs to the field of calibration and positioning devices for horizontal reference planes during the manufacture of railway passenger car bogies, and in particular relates to a slider type floating support device. Background technique [0002] The manufacturing process of the railway passenger car bogie involves multiple machining links such as marking, processing, and press repair of the frame workpiece. The type of support element is used for horizontal alignment and positioning of the workpiece on the reference plane. [0003] Conventional support elements such as spiral tops used for datum calibration have design shortcomings and deficiencies in terms of reliability, safety, and ease of operation. When the reference plane is used for horizontal calibration and positioning, there is rotational friction between the contact surface between the tip and the frame workpiece, which often causes horizontal displacement of the frame and aff...

Problems solved by technology

[0004] In order to solve the problem of horizontal calibration and positioning of the reference plane of the frame to be processed on the machine tool platform such as a scribing machine or a press machine for the existing application of the spiral tip, there is rotating friction between the tip and the contact surface of the frame workpiece, which will affect the level of the frame. In addition, the operator needs to reach out to the top of the rotating spiral top under the frame, which is not only difficult to operate, but also has an unsatisfactory viewing angle, and there are technical problems of potential safety hazards. The present invention provides a slider-type floating Supporting device
