Description
Technical Field
The utility model belongs to a supporting device, and particularly relates to a universal ball damping supporting device.
Background
The mould of a certain large welding device is connected with the rotary table of the position changer through the lower flange, and operators need to enter the mould from the bottom to operate when in use, so that the outer diameter of the connecting flange is limited, and enough space is reserved for personnel to enter and exit. Because the diameter of the outer edge of the die is large, the die and accessory parts thereof are heavy, and a person also needs to tread the outer edge of the die during external operation, the problem of poor system rigidity after unbalanced load is obvious. In order to improve the stability and reliability of the operation of the equipment, it is necessary to add auxiliary supports on the bottom surface of the outer edge of the mold.
On the one hand, because the mould will rotate along with the rotary table of the positioner when working, the auxiliary support and the bottom surface of the outer edge of the mould cannot be fixedly connected, if the sliding friction is formed by adopting a plane to a plane, the abrasion of the mould and the support device is easy to accelerate due to the larger friction coefficient, the long-term operation of the equipment is not facilitated, and the preferable scheme adopts rolling friction. The roller is in butt joint with the bottom surface of the outer edge of the die, the problem is that the contact line of the roller and the bottom surface of the outer edge of the die is difficult to ensure centripetal relative to the annular surface of the outer edge of the die during installation, rolling smoothness cannot be ensured, further improvement measures are that the roller is movably connected with a base of the roller to form a universal wheel, but the roller is damaged after being used for a short time, and the analysis reason is that the direction adjustment response speed is not fast enough when a plurality of rollers are combined for use, so that the self-adaption purpose cannot be achieved;
on the other hand, because the external dimension of the mould is larger, the dimension of the bottom surface of the outer edge and the shape and position accuracy are inevitably deviated, the supporting device is required to have a damping adjustment function in the height direction, and meanwhile, when unbalanced load occurs, the supporting device is required to ensure enough supporting rigidity while providing reliable supporting. Accordingly, there is a need for a support device that overcomes the above-mentioned drawbacks.

Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings.
Examples:
the universal ball damping support device comprises a universal ball 1, a guide seat 2, a spring 3, a height adjusting disc 4, a base 5, a limit baffle 6, a support shaft 7 and a gland 8. The supporting shaft 7 is connected to the base 5 through trapezoidal threads, and the limiting baffle 6 is installed at the lower end of the supporting shaft 7 to prevent the supporting shaft from falling out of the base 5. The height-adjusting disc 4 is sleeved on the supporting shaft 7 through a central square hole and is tightly pressed by the pressing sleeve 8. The inner hole of the guide seat 2 is in sliding fit with the small end outer cylindrical surface of the height-adjusting disc 4, can slide up and down along the height-adjusting disc 4, and is limited by the flange at the upper end of the gland 8. The spring 3 is sleeved between the height-adjusting disc 4 and the guide seat 2, the lower end face is abutted with the height-adjusting disc 4, and the upper end face is abutted with the bottom surface of the groove of the guide seat 2. The universal ball 1 is in threaded connection with the large end face of the guide seat 2. The universal ball is heavy-duty, has enough supporting rigidity, ensures that the outer edge of the die does not deform greatly when unbalanced load occurs, and supports the steel ball to roll smoothly without clamping stagnation. The spring is used for damping the supporting device in the height direction so as to adapt to the size and shape fluctuation of the contact part between the large-diameter die and the universal ball in the rotation process.
The large end of the guide seat is a square flange, the small end of the guide seat is hollow and columnar, a step hole is formed in the guide seat, a groove is formed in the guide seat, the cylindrical surface of the groove is used for guiding a spring, and the bottom surface of the groove is abutted to the end surface of the spring.
The center of the height-adjusting disc is a square hole, the outer circle of the large end is knurled with reticulate patterns so as to be screwed, and 8 radial holes are uniformly distributed along the circumference and are used for operating by an extension rod when the screwing force is large. The excircle of the small end of the height-adjusting disc is matched with the central hole of the guide seat, and the excircle of the middle part is used for guiding the spring.
The outside of the supporting shaft is provided with trapezoidal threads which are matched with the central screw hole of the base, the upper part is provided with square flat potentials which are matched with the central square hole of the heightening disc, and the two ends of the supporting shaft are respectively provided with screw holes for connecting the limit baffle and the gland.
When the device works, the anticlockwise screwing height-adjusting disk can drive parts such as the supporting shaft and the like to move upwards until the universal ball contacts an object to be supported, when the supported object moves downwards under the action of external force such as unbalanced load and the like, the upper part of the universal ball is pressed, the guide seat is driven to slide downwards along the small-end outer column surface of the height-adjusting disk, the supporting force provided by the spring while the compression amount of the spring is increased along with the small-end outer column surface until the downward pressure and the supporting force are balanced. When the load-bias disappearing position of the supported object moves upwards, the spring rebounds to drive the guide seat to slide upwards to restore to the initial state. The supporting height can be reduced by screwing the height-adjusting disk clockwise, and the supporting device can be removed when the gap between the universal ball and the supported object is enough.
