Abstract
The invention discloses a side pressure supporting body for a universal mill. The supporting body comprises a V-shaped bracket, wherein a supporting shaft is installed at the middle of the V-shaped bracket; the lower end of the supporting shaft is connected with a worm gear by screws; the worm gear is driven to rotate by a worm which is installed at the side of the worm gear; a spring is arranged above the worm gear; a ring nut is arranged above the spring and is fixed above the inner side of the V-shaped bracket; the worm gear and the spring are both positioned in the V-shaped bracket, and a no-clearance adjusting device is arranged between the worm gear and the spring. The side pressure supporting body for the universal mill adopts the structure that the no-clearance adjusting device is arranged between the worm gear and the spring so as to achieve the no-clearance adjustment, thereby improving the accuracy, and solving the problem that the transmission of the worm gear is easy to deviate.
Description
Technical field
The present invention relates to mechanical equipment technical field, particularly a kind of side pressure supporter for universal mill.
Background technology
At universal mill, generally comprise screw-down, lateral pressing structure of shoe and roll stacks etc.The side pressure supporter of universal mill in prior art, the inner Worm Wheel System that uses, drive back shaft moves up and down, worm screw easily tilts to cause a deviation or is stuck when with back shaft relative motion, affect the work of the side pressure supporter of whole universal mill, and there is gap in worm-drive process, cause transmission accuracy not high.
Summary of the invention
The technical issues that need to address of the present invention are that the side pressure supporter worm-drive of universal mill in prior art exists gap, and transmission accuracy is not high.
For solving the problems of the technologies described above, the invention provides a kind of side pressure supporter for universal mill, comprise V-type support, back shaft is installed in the middle of described V-type support, in described back shaft lower end, be threaded connection worm gear, described worm gear is driven and is rotated by the worm screw that is arranged on its side, above described worm gear, be provided with spring, above described spring, be provided with ring nut, described ring nut is fixed on described V-type support inside front, described worm gear and spring are all positioned at described V-type internal stent, between described worm gear and spring, be also provided with gapless adjusting device.Side pressure supporter for universal mill of the present invention, realizes gapless adjustment by lash adjusting device being set between worm gear and spring, improves precision, solves the problem of the easy deviation of worm-drive.
As the preferred technical solution of the present invention, described gapless adjusting device comprises adjustment packing ring, described adjustment packing ring and back shaft are threaded connection, and described adjustment packing ring below is fixedly connected with described worm gear by a circle steady pin, and the distance between described adjustment packing ring and worm gear is 1-3mm.Distance between wherein said adjustment packing ring and worm gear is that 2mm is preferred distance.By fix one on worm gear, adjust packing ring, and the spacing of adjusting between packing ring and worm gear is fixed on to 2mm left and right, like this worm gear together with adjusting packing ring with back shaft relative motion, can realize stable drive, the high deviation of precision is little, the degree of balance is high, is not easy stuckly, and worm gear can gapless adjustment.
As a further improvement on the present invention, described worm screw is 2, respectively the symmetrical both sides that are positioned at described worm gear.With 2 worm screws, drive worm gear to rotate, increase power, raise the efficiency, and easy to maintenance, do not affect work.
Side pressure supporter for universal mill of the present invention, inside is provided with worm gear gapless adjusting device, worm-drive is steady, and the high deviation of precision is little, the degree of balance is high, has really realized the gapless adjustment of worm gear, makes the modification stability of height up and down of back shaft smooth and easy, and raising precision, thereby the quality of raising converted products.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1-V type support, 2-back shaft, 3-worm gear, 4-worm screw, 5-spring, 6-encircles nut, and 7-adjusts packing ring, 8-steady pin.
The specific embodiment
Below in conjunction with accompanying drawing, describe the preferred technical solution of the present invention in detail.
As shown in the figure, side pressure supporter for universal mill of the present invention, comprise V-type support 1, in the middle of described V-type support 1, back shaft 2 is installed, in described back shaft 2 lower ends, be threaded connection worm gear 3, described worm gear 3 is driven and is rotated by two worm screws 4 that are arranged on its both sides, above described worm gear 3, be provided with spring 5, above described spring 5, be provided with ring nut 6, described ring nut 6 is fixed on described V-type support 1 inside front, described worm gear 3 and spring 5 are all positioned at described V-type support 1 inside, between described worm gear 3 and spring 5, be also provided with gapless adjusting device, described gapless adjusting device comprises adjusts packing ring 7, described adjustment packing ring 7 is threaded connection with back shaft 2, described adjustment packing ring 7 belows are fixedly connected with described worm gear 3 by a circle steady pin 8, distance between described adjustment packing ring 7 and worm gear 3 is 2mm.
Side pressure supporter for universal mill of the present invention, realizes gapless adjustment by lash adjusting device being set between worm gear and spring, improves precision, solves the problem of the easy deviation of worm-drive.
By fix one on worm gear, adjust packing ring, and the spacing of adjusting between packing ring and worm gear be fixed on to 2mm left and right, like this worm gear together with adjustment packing ring with back shaft relative motion, can realize stable drive, the high deviation of precision is little, and the degree of balance is high, is not easy stuck, worm gear can gapless adjustment, with 2 worm screws, drive worm gear to rotate, increase power, raise the efficiency, and easy to maintenance, do not affect work.
Side pressure supporter for universal mill of the present invention, in the process of work, there is worm screw to drive worm gear to rotate, worm gear drives adjustment packing ring to rotate together, worm gear and adjustment packing ring drive whole back shaft to move up and down by screw thread transmission, owing to fixing by a plurality of steady pins between worm gear and adjustment packing ring, and the spacing between worm gear and adjustment packing ring immobilizes, transmission between that so worm gear can balance and stability and back shaft, being difficult for deviation tilts to cause transmission stuck, affect operating efficiency, and increase gapless adjusting device can also be raised the efficiency, increase the service life, achieve many things at one stroke.
Side pressure supporter for universal mill of the present invention, inside is provided with worm gear gapless adjusting device, worm-drive is steady, and the high deviation of precision is little, the degree of balance is high, has really realized the gapless adjustment of worm gear, makes the modification stability of height up and down of back shaft smooth and easy, and raising precision, thereby the quality of raising converted products.
