Description
Technical field
The utility model relates to a kind of swiveling table, and particularly a kind of swiveling table that is used for the gear induction hardening process belongs to mechanical engineering technical field.
Background technology
Swiveling table is a component machining tool annex common in the mechanical engineering, and it has rotating table top, in order to clamping workpiece and realize revolution and calibration location, and abbreviation turntable or the 4th.The induction hardening process of gear also can be realized through swiveling table; But pursuing in the tooth induction quenching process of gear; Gap between inductor block and the gear need be controlled accurately, and the gear after just guaranteeing to quench obtains even, qualified hardened layer.
Therefore, the swiveling table of placing gear there is following requirement: one, can smooth turn round; Two, gear can be by stable being fixed on the swiveling table, and guaranteeing to quench is not subjected to displacement when carrying out; Three, the wheel tooth end surface is beated in 0.05mm; Four, the gear teeth tips disc is beated in 0.05mm.
The utility model content
The purpose of the utility model is: the problem to above-mentioned prior art exists, a kind of swiveling table is provided, compact construction, rigidity is good, revolution is smooth, be applicable to gear by the tooth induction quenching.
The purpose of the utility model realizes through following technical scheme:
A kind of swiveling table; Comprise turntable and pedestal, said turntable comprises cylindrical main body and the table top that is positioned at the main body stage casing, and main body has two free ends up and down along vertical direction; Said pedestal is a right cylinder; Its inner chamber is accommodated the following free end of the main body of turntable, is connected through bearing between said turntable and the pedestal, and said bearing comprises horizontally disposed thrust ball bearing and vertically disposed angular contact ball bearing and deep groove ball bearing.
Preferably, also be provided with spacer between said angular contact ball bearing and the deep groove ball bearing.
Preferably, also be provided with trim ring on the following free end of said main body, be connected with turntable, through the screw thread preliminary tension between the two, the position between solid bearing, turntable, the pedestal through screw thread.
Preferably, also comprise the hold-down nut on the last free end that is threaded in main body, provide axial force to compress by the screw thread preliminary tension and be placed on the gear workpiece between the two.
Preferably, also be provided with the horizontal adjustment nut on the main body of said turntable, provide radial pressure adjustment gear disc to beat by the screw thread preliminary tension; Said gear teeth tips disc is beated to be controlled in the 0.05mm; Gear more stably is fixed on the swiveling table, guarantees that gear is not subjected to displacement, and makes the gap between gear and the inductor block precisely controlled when quenching; Like this, the hardened layer that obtains behind the gear quenching can be more even.
Further preferred, also be provided with vertical adjustment nut on the table top of said turntable, provide axle pressure adjustment gear face to beat by the screw thread preliminary tension, said wheel tooth end surface is beated be controlled in the 0.05mm.Gear more stably is fixed on the swiveling table, guarantees that gear is not subjected to displacement when quenching, make the gap between gear and the inductor block obtain controlling more accurately, can obtain hardened layer more uniformly behind the gear quenching.
The beneficial effect of the utility model is mainly reflected in: because the turntable and the pedestal of swiveling table utilize deep groove ball bearing, angular contact bearing, thrust ball bearing to interconnect; Therefore; Can be respectively from axially with the footpath even bearing load that makes progress, realized swiveling table steadily, accurately running.
If further adopt the mode of horizontal adjustment nut and vertical adjustment nut; The face runout of wheel tooth portion is beated in 0.05mm with interior, gear teeth tips disc at 0.05mm; Then can make more stable being fixed on the swiveling table of gear; Realize the more accurately control in gap between gear and the inductor block, thereby make gear obtain hardened layer more uniformly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model swiveling table.
