Description
Technical field
The present invention relates to leading screw technical field, more particularly to lifting apparatus during a kind of swing of speciality leading screw.
Background technology
In automated production trim designs manufacturing process, the application of leading screw has the advantages that transmission is quick, carrying is big, but
It is, if the leading screw that equipment needs is oversize, because rigidity deficiency may result in the upper bottom of leading screw or so in the process of running
Dynamic, it is inadequate to ultimately result in transmission precision, therefore, solve this it is a kind of be particularly important, and traditional fixing device is usually
Fast knot structure, have sliding shoe in operation, on leading screw and move back and forth, if lifting apparatus is the dead work that will influence leading screw
Make, therefore, solve the problems, such as that this kind of is particularly important.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of leading screw antihunting lifting apparatus, by being provided with cylinder
The bearing group of control places leading screw, to improve the stability of leading screw in the process of running.
In order to solve the above problems, the invention provides a kind of leading screw antihunting lifting apparatus, include leading screw, described
Fixed support is provided with below leading screw, the cylinder with guide rod is provided with the fixed support, the cylinder is consolidated by bolt
On fixed support, the upper end of the guide rod is provided with bracket, the upper surface of the bracket is provided with bearing block, institute for Dingan County
State and symmetrical bearing is provided with bearing block, be provided between described two bearings and place arc groove for leading screw placement.
Further improvement is that：The both sides of the bracket lower end are respectively arranged with support bar, and the support bar is telescopic
, flexible according to guide rod therewith lifts.
Further improvement is that：Symmetrical bearing forms a bearing group, at least provided with two on the bracket
Bearing group.
Further improvement is that：The junction of the bracket and bearing block is provided with resilient sleeper-bearing, and the resilient sleeper-bearing leads to
Cross and be bolted on bracket.
The beneficial effects of the invention are as follows：The present invention places leading screw by being provided with the bearing group of cylinder control lifting, with
The stability of leading screw in the process of running is improved, when sliding block slides into lifting apparatus, the orderly avoidance of bearing group energy, the present invention
It is simple in construction, easy to operate, flexibly controllable.
Brief description of the drawings
Fig. 1 is the front view of the present invention.
Fig. 2 is the side view of the present invention.
Wherein：1- leading screws, 2- fixed supports, 3- guide rods, 4- cylinders, 5- brackets, 6- bearing blocks, 7- bearings, 8- arc grooves, 9-
Support bar, 10- resilient sleeper-bearings.
Embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in Figure 1, 2, a kind of leading screw antihunting lifting apparatus is present embodiments provided, includes leading screw 1, in the silk
The lower section of thick stick 1 is provided with fixed support 2, and the cylinder 4 with guide rod 3 is provided with the fixed support 2, and the cylinder 4 passes through spiral shell
Bolt is fixedly mounted on fixed support 2, and the upper end of the guide rod 3 is provided with bracket 5, is provided with the upper surface of the bracket 5
Bearing block 6, symmetrical bearing 7 is provided with the bearing block 6, be provided between described two bearings 7 and place arc groove 8
Laid for leading screw.The both sides of the lower end of bracket 5 are respectively arranged with support bar 9, and the support bar 9 is telescopic, according to leading
The flexible of bar therewith lifts.Symmetrical bearing 7 forms a bearing group, at least provided with two axles on the bracket 5
Hold group.The junction of the bracket 5 and bearing block 6 is provided with resilient sleeper-bearing 10, and the resilient sleeper-bearing is bolted on support
On frame.
In leading screw longitudinal direction, appropriate position, fixed support are weldingly fixed on ad-hoc location, initial position adjustment as needed
Bearing can be lifted to leading screw during cylinder range, and when leading screw works, cylinder range is lifted, and be realized anti-
Only leading screw swing purpose, when lift position have sliding block by when, programme-control air cylinder guide rod retract, concede position to sliding block
Put, when sliding block by after, air cylinder guide rod is elongated to range again, continues to lift leading screw.
The present invention places leading screw by being provided with the bearing group of the control lifting of cylinder 4, to improve leading screw in the process of running
Stability, when sliding block slides into lifting apparatus, the orderly avoidance of bearing group energy is of the invention simple in construction, easy to operate, flexible
It is controllable.
