Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

a hot metal bottle ear shaft hole cutting and positioning device comprises a support 1 and a positioning device 2, wherein the positioning device 2 comprises a positioning rod 3, a rotary sleeve 4 and a connecting plate 5, the positioning rod 3 is vertically connected on the support 1, the rotary sleeve 4 is slidably connected on the positioning rod 3, one end of the connecting plate 5 is fixedly connected on the outer wall of the rotary sleeve 4, the upper end of the positioning rod 3 is attached to the outer surface of a hot metal bottle, the opening center of the ear shaft hole is determined by the positioning rod 3 on the positioning device 2, then a marking tool or a cutting tool is connected at the other end of the connecting plate 5, the marking and cutting work can be completed by rotating the rotary sleeve 4 by one circle of the connecting plate 5, because the side wall of the hot metal bottle is an arc surface, the rotary sleeve 4 can slide on the positioning rod 3, the rotary sleeve 4 can slide up and down in the rotating process, and further can enable the marking tool or the cutting tool to be attached to the side wall of the hot metal bottle all the time, thereby guarantee that the earmuff hole after the cutting accords with the designing requirement, set up the cooperation that 4 inner walls of swivel mount and locating lever 3 can also be guaranteed to swivel mount 4 simultaneously, reduce the error, also be convenient for change if 4 wearing and tearing of swivel mount.

Further 3 upper ends of locating lever be equipped with location conical head 301, location conical head 301 top and hot metal bottle surface laminating set up 3 upper ends of locating lever into location conical head 301, utilize the sharp point at location conical head 301 top can better complete positioning work, reduce the error.

Further connecting plate 5 the other end be equipped with fixed connection hole 501, fixed connection hole 501 extends vertical direction and runs through connecting plate 5, can directly be fixed marking tool or cutting tool through fixed connection hole 501 to the horizontal distance between fixed connection hole 501 axis to 3 axis of locating lever is the cutting radius in ear axle hole promptly, has stabilized the machining precision more like this.

Further positioner 2 be equipped with threely, three positioner 2's hookup location sets up three positioner 2 and can once only fix a position the cutting with the three otic placode hole of hot-metal bottle one side at an isosceles triangle's three apex to guarantee that the relative position in three otic placode hole is more accurate.

Further 3 lower extreme of locating lever be equipped with screw thread portion 302, locating lever 3 and 1 threaded connection of support utilize the height position of the adjustable locating lever 3 of screw thread portion 302 of 3 lower extremes of locating lever, because the arc degree of hot metal bottle outer wall can not guarantee unanimously in process of production, has a little difference, consequently when three point location, the condition that three points can not contact simultaneously can appear, consequently the locating lever 3 can guarantee through the slight adjustment of upper and lower position the utility model discloses a normal use.

Further be connected with lock nut 303 on the screw thread portion 302 two, two lock nut 303 set up respectively in support 1 upper and lower both ends, lock the locating lever after adjusting through two lock nut 303, guarantee the machining precision.

During the use, place the molten iron jar level, will again the utility model discloses the level is placed in molten iron jar lateral wall below, then alignment earhole hole cutting position, closely laminates 3 upper ends of locating lever and molten iron jar lateral wall, and locating lever 3, support 1 and molten iron jar are fixed to become a whole this moment, then connect marking tool or cutting means in fixed connection hole 501, through rotating 5 a week of connecting plate, can accomplish and rule or cutting work.
