Abstract
The utility model discloses a following non-rotational screw jack, comprising a pedestal (7) and a lifting-capable screw rod (6) mounted on the pedestal, wherein the top of the screw rod is sleeved with a ball thrust sleeve (3), a free cover on the top of a ball of the thrust sleeve is equipped with a following head (1), the neck at the upper end of the screw rod is provided with an annular groove (6a), the lower edge of the ball thrust sleeve (3) is equipped, in a matched manner, with the screw rod (6) via a thrust bearing (5), a fixed ring of the thrust bearing is mounted, in a matched manner, in the annular groove at the upper end of the screw rod, a movable ring of the thrust bearing is equipped, in a matched manner, with the lower edge of the ball thrust sleeve, and the thrust bearing is externally sleeved with a disengagement-preventing protective cover (4). The following non-rotational screw jack can support an uneven supporting face in a following and tightly-attached manner, and simultaneously, a supporter of the supporting face only moves vertically without rotation, thereby achieving great safety and reliability.
Description
Technical field
The utility model belongs to the jack structure technical field.
Background technology
Hydraulic jack does not generally all use under the situation of machine up and the long-time holding workpieces of need owing to pressurize for a long time.At machinery, chemical industry, light industry, heavy industry, equipment manufacture, and in the installation of various kinds of equipment, adjustment, maintenance, what extensively adopt is lifting screw.But there are two shortcomings in general lifting screw: the one, and its support is risen the rotation jack or when descending, jack and support contact surface can produce slide relative, sometimes even support is and then rotated together.The 2nd, if the contact surface unfairness of support and jack is unreliable when being supported with, when serious even can topple over.And in the machine up of reality, have a lot of large-scale workpieces using jack adjustment level on the large-scale vertical lathe or on the floor type boring machine, and the black skin of this class workpiece usually is irregular, when particularly processing is as the workpiece of turbine blade one class, its areal of support or even curved surface.In the fitting process of a lot of parts, people wish that the supporting member of jack is only mobile vertically and do not rotate.Existing lifting screw all is difficult to meet the demands.
Summary of the invention
The purpose of this utility model provides a kind of for the deficiency that solves above-mentioned prior art existence just can be adjacent to supporting with irregular areal of support servo-actuated, makes its supporting member only move up and down and not rotate simultaneously, and safe and reliable servo-actuated is the rotating screw jack not.
The purpose of this utility model is achieved by the following technical solution.
Servo-actuated is the rotating screw jack not, be set with the bulb thrust sleeve at the top of screw rod, the bulb top of thrust sleeve is freely covered the servo-actuated head is housed, neck offers annular groove in the screw rod upper end, bulb thrust sleeve lower edge is equipped by thrust baring and screw rod, the circle of deciding of thrust baring is fitted in the screw rod top ring connected in star, and the lower edge of the moving-coil of thrust baring and bulb thrust sleeve is equipped, is set with the anticreep guard shield outside thrust baring.
The equipped face of servo-actuated head of the present utility model and bulb thrust sleeve is a sphere.On the servo-actuated head, be fitted with the anti-skid screw of horizontal top to the bulb thrust sleeve.Be provided with flange in bulb thrust sleeve bottom, anticreep guard shield lower end is by being threadedly connected to the screw rod outside face, and the upper end is by hooking the flange of bulb thrust sleeve.
This jack rotates flexibly, and support only moves up and down and do not rotate with jack.Also can reduce the requirement to institute's areal of support simultaneously, areal of support misconduct or suitable inclination all can effectively be supported.
Further set forth content of the present utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the utility model comprises base 7, is installed on liftable screw rod 6 in the base, be set with bulb thrust sleeve 3 at the top of screw rod, the bulb top of thrust sleeve is freely covered servo-actuated 1 is housed, neck offers annular groove 6a in the screw rod upper end, and bulb thrust sleeve 3 lower edges are equipped with screw rod 6 by thrust baring 5, and the circle of deciding of thrust baring is fitted in the screw rod top ring connected in star, the lower edge of the moving-coil of thrust baring and bulb thrust sleeve is equipped, is set with anticreep guard shield 4 outside thrust baring.The thrust sleeve bulb is through Quenching Treatment.The equipped face of servo-actuated head and bulb thrust sleeve can be processed into the plane, but preferably is processed as sphere, with the area of contact of increase with the bulb thrust sleeve, reduces contact stress.Because servo-actuated 1 is freely to cover on the bulb thrust sleeve 3, for preventing that the servo-actuated head from losing, on the servo-actuated head, be fitted with the anti-skid screw 2 of horizontal top to the bulb thrust sleeve, tighten anti-skid screw during without jack, unscrew during use, so that the servo-actuated head is swung flexibly with areal of support.Come off for preventing that thrust baring from separating, designed anticreep guard shield 4, be provided with flange 3a in bulb thrust sleeve 3 bottoms, anticreep guard shield lower end is by being threadedly connected to the screw rod outside face, the flange 3a that the bulb thrust sleeve is hooked in the upper end stays appropriate gap during assembling, thrust sleeve can be rotated freely.The anticreep guard shield is because stressed less, and available plastics are manufactured.
When with spanner or driving lever rotary screw 6, the friction of thrust baring 5 is far smaller than servo-actuated 1 and is supported friction between the workpiece, therefore servo-actuated head and bulb thrust sleeve 3 all can not rotate, and only move along screw axis, guaranteed that workpiece only moves and do not rotate toward a direction that needs, the servo-actuated head can suitably be swung arbitrarily on the thrust sleeve bulb and be adjacent to areal of support.When a servo-actuated drift angle was big, center of effort's line may exceed base 7 disks, at this moment only need be pressed on base on the bench board to get final product.
Use this jack, can reduce clamping, the correction time of a lot of large-scale workpieces, and improve the reliability of adjusting accuracy and supporting.
