Abstract
The utility model relates to train wheel manufacture technology field, in particular relates to a train wheel plate hole drilling-assisted device. The technical scheme of the utility model is as follows: the train wheel plate hole drilling-assisted device is mainly composed of a supporting stage, a pressing plate and a positioning sleeve, wherein the positioning sleeve cooperates with a shaft hole of a wheel to realize the positioning of the wheel. The center of the positioning sleeve is connected with the supporting stage through a stud and a nut, the periphery of the positioning sleeve is connected with the pressing plate which is in symmetric distribution; a guide hole is arranged on the pressing plate; and a guide sleeve is arranged inside the guide hole. When the drilling-assisted device is used, firstly, the wheel is fixed on the supporting stage through the pressing plate, the stud and the nut, wherein the positioning sleeve which is assembled on the pressing plate is buckled with the shaft hole of the wheel in a matched manner, such that the positions of each part (especially the positioning sleeve) on the whole pressing plate with respect to the shaft hole of the wheel are ensured; and then, a drill is used for drilling through the guide sleeve which can avoid deflection when the drill is used for drilling a hole on a curved surface. The train wheel plate hole drilling-assisted device of the utility model has the advantages of simple structure, convenient use, low cost and high-accuracy positioning.
Description
Technical field
The utility model relates to train wheel manufacturing technology field, is specifically related to a kind of train wheel plate hole boring servicing unit.
Background technology
Make the field at train wheel; Require on curved surface, to bore hole for hoist to the part train wheel, and certain status requirement is arranged, owing to be that curved surface does not add servicing unit drill bit meeting beat on common driller; The hole that gets out has problem; And still do not have a kind of servicing unit can directly cooperate common radial drill to use at present, and therefore must not add other equipment, therefore improved production cost greatly.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of simple in structure, with low cost and train wheel plate hole boring servicing unit that can cooperate existing common radial drill to use is provided.
Its technical scheme is: mainly be made up of brace table, pressing plate, positioning sleeve; Wherein positioning sleeve cooperates the realization wheel alignment with the axis hole of wheel; Positioning sleeve center and brace table through double-screw bolt and nut be connected, periphery is connected with the pressing plate of symmetrical distribution; Pressing plate is provided with pilot hole, and fairlead is installed in the pilot hole.At first through pressing plate and double-screw bolt, nut wheel is fixed on the supporting station during use, the positioning sleeve of assembling on its center platen cooperates with the wheel axis hole and is installed, and guarantees the position of each parts on the whole pressing plate (especially positioning sleeve) with respect to the wheel axis hole; Drill bit is through fairlead boring then, and fairlead can guarantee the drill bit not beat of on curved surface, holing.
Adopt the changeable type fairlead, fairlead and pressing plate adopt interference fit, when the fairlead wearing and tearing are relatively more serious, only need to change fairlead and get final product, and save cost, owing to adopt interference fit, can not influence its precision.Fairlead can be set to two, and fairlead adopts harder material and Quenching Treatment.Positioning sleeve is that easy disassembly and pressing plate adopt matched in clearance, and through two screw attachment.
Connect handle on the pressing plate, convenient carrying.Brace table is a weld assembly, and the upper and lower end face need guarantee certain depth of parallelism.
The utlity model has advantage simple in structure, easy to use, with low cost and that positioning accuracy is high, use this device, can directly use common radial drill can accomplish the boring processing of train wheel plate hole, therefore greatly reduce production cost.

The specific embodiment
Referring to Fig. 1-2; A kind of train wheel plate hole boring servicing unit; Mainly be made up of brace table 1, pressing plate 3, positioning sleeve 6, wherein positioning sleeve 6 cooperates with the axis hole of wheel and realizes wheel 2 location, and positioning sleeve 6 centers and brace table 1 are connected, peripherally also are connected through screw 9 with two block pressur plates, 3 matched in clearance of symmetrical distribution through double-screw bolt 7 and nut 8; Every block pressur plate 3 is provided with a pilot hole, through interference fit fairlead 4 is installed in the pilot hole.Also be welded with handle 5 on the pressing plate 3.
Before the boring, double-screw bolt 7 is fixed on earlier on the brace table 1, wheel 2 is winched to (double-screw bolt need pass axis hole, like figure) on the brace table, pressing plate 3 and positioning sleeve 6 are assembled, be pressed on the wheel 2 nut 8 of screwing with crane.Final clamping form is with reference to looking accompanying drawing 1.During boring, drill bit is through fairlead 4 location; After having bored, screw off nut 8, take down pressing plate 3 and positioning sleeve 6, hang down wheel 2; So repeatedly.
Claims (3)
1. train wheel plate hole boring servicing unit; It is characterized in that: mainly form by brace table, pressing plate, positioning sleeve; Wherein positioning sleeve cooperates the realization wheel alignment with the axis hole of wheel; Positioning sleeve center and brace table through double-screw bolt and nut be connected, periphery is connected with the pressing plate that is symmetrically distributed, pressing plate is provided with pilot hole, the interior installation of pilot hole fairlead.
2. train wheel plate hole boring servicing unit according to claim 1, it is characterized in that: adopt the changeable type fairlead, fairlead and pressing plate adopt interference fit; Positioning sleeve and pressing plate adopt matched in clearance, and connect through screw.
