Abstract
The invention relates to a supporting and levelling device and a test stand using the supporting and levelling device. An adjusting sleeve which is arranged between a pressing nut and an adjusting screw is sleeved on the periphery of a pressing bolt of the levelling device; a rotation stop structure which is matched with the adjusting bolt to drive the adjusting screw to move up and down is arranged on the lower end of the adjusting sleeve. When the supporting and levelling device is used, the operator can rotate the adjusting sleeve by a wrench, so that the rotation stop structure on the lower end of the adjusting sleeve drives the adjusting screw to move up and down, thereby adjusting the height of a supported body; when the operator adjusts the supported body, the wrench which is matched with the levelling device for use is arranged above the supported body, so as to solve the problem that the levelling device in the prior art is time-wasting and force-saving to operate below the supported body, and thus the operator can conveniently and quickly level the supported body at a determined height.
Description
Technical field
The present invention relates to a kind of support levelling device in the mechanical positioning technical field, also relate to a kind of test-bed that uses this support levelling device simultaneously.
Background technique
At present, the experimental scale along with engine test constantly enlarges the also constantly expansion of panel size that threst stand is required; Some surpasses the weight of required flat board more than 100 tons, but because a traditional test bay only uses one flat plate, thereby make that dull and stereotyped cost of transportation is excessive; Also increased simultaneously dull and stereotyped casting difficulty; And then caused some dull and stereotyped castability to guarantee, and the processing of plane on the flat board and T type groove also can not find suitable lathe, so the flat board of test bay just must be spliced through the polylith flat board; Thereby in splicing; Affected personnel just must guarantee each plate height conformity, avoid the high infraversion malposition of seam crossing, and the equipment that influences is installed.It is stressed evenly that but the lathe that uses on the existing market can not respectively be adjusted parallels in assurance with the adjustment parallels, adjusts to sustained height.
Application number is that 201020155522.6 Chinese invention patent discloses a kind of lathe leveling securing means; This device mainly is made up of pedestal, adjusting screw rod, stud bolt and gland nut, axially extending along the vertical direction of stud bolt wherein, and the lower end coaxial threaded of stud bolt is connected in the tapped hole that base bottom offers; Stretch out in the axial hole of offering in the adjusting screw rod that the upper end connects from pedestal upper end coaxial threaded; And be threaded with gland nut through external part, and an end of adjusting screw rod is in the endoporus of pedestal, convexes with on the periphery of the other end and be used for turning edge of support plate; In use; The operator regulates turning edge of adjusting screw rod through direct rotation adjusting screw rod and goes up the height of the mounting plate that supports, thereby reaches the purpose of leveling mounting plate, but because adjusting screw rod is in the mounting plate below; Therefore in the process of leveling mounting plate; The instrument that the operator needs to be used to rotate adjusting screw rod stretches into the mounting plate below, and the position of, device for installing and leveling big at the mounting plate area is during near the inboard, and the operator has only mounting plate is pulled down the height that could regulate adjusting screw rod from levelling device; And then make the increase consuming time of leveling process of mounting plate; And when pulling down the mounting plate leveling, the operator can only by virtue of experience regulate levelling device with sensation, thereby the amount of labour increase that makes the accuracy of leveling reduce, need expend.
