Abstract
The utility model relates to an inner pore induction quenching and cooling device. The middle part of a spindle is supported by virtue of a bearing block, a sealing seat fixed at the upper part of the bearing block is sheathed on the spindle, a lip-type sealing ring used for sealing the spindle is arranged in a groove of the sealing seat, a sealing cover fixed with the sealing seat is compacted on the lip-type sealing ring, an upper cover fixed on the spindle is arranged above the sealing seat, a positioning mould used for supporting a workpiece is arranged at the upper part of the upper cover, a synchronous pulley is fixed at the lower part of the spindle, the spindle is a hollow shaft, the top of the spindle is arranged in an inner pore of the positioning mould, the top end of the spindle is closed, a side hole is communicated with a center hole on the spindle, and the lower end of the spindle is connected with a cooling pipeline provided with a valve by virtue of a rotary joint. The inner pore induction quenching and cooling device has the advantages that quenching medium is filled in the inner pore of the workpiece by virtue of a hollow spindle from the bottom up, cooling is realized, quenching capacity of the workpiece is improved without influencing rotating and heating of the workpiece, the problem that an inductor holds back water is solved and workpiece quenching quality is improved.
Description
Technical field
The utility model relates to quenching cooler, especially a kind of endoporus induction quenching refrigerating unit.
Background technology
At present, the modal endoporus induction quenching type of cooling is to adopt inductor block to carry water-jet cooling, i.e. heating finishes rear rapid travelling workpiece and sprays water cooling to water-jet position.For the smaller part that there is no spatial design suspension type water-jet of some endoporus, adopt the mode of directly spraying water from inductor block top alignment bore, because the dash of inductor block easily causes work-piece cools bad, there is quenching soft spot in quenching position, cause workpiece normally not use, or shorten the phenomenons such as workpiece life-span.
Summary of the invention
The purpose of this utility model is to provide a kind of endoporus induction quenching refrigerating unit, overcomes the problem of the cooling detrimentally affect workpiece quality of workpiece quenching.
The purpose of this utility model realizes as follows: main shaft middle part is supported by bearing support, on main shaft, cover has the sealing socket that is fixed on bearing support top, the lip-type packing of device to shaft seal in sealing socket groove, in lip-type packing, compress and have the sealing cover fixing with sealing socket, sealing cover top arranges the upper cover being fixed on main shaft, upper cover top is provided for the positioning clamping fixture of supporting workpiece, synchronous pulley is fixed in main shaft bottom, main shaft is tubular shaft, in the endoporus of spindle top in positioning clamping fixture, main shaft top closure and have side opening to communicate with centre hole, main shaft lower end is connected with being with valvular cooling duct by swivel joint.Synchronous pulley makes main shaft rotation to main shaft transmitting torque, and main shaft is carried quenchant as cooling duct again simultaneously.The main shaft and the cooling duct that connect hollow by swivel joint, when making workpiece rotary heating, cooling duct does not rotate.Main shaft upper end closed and overflowing by quenchant at flank hole, is to guarantee that quenchant can directly not spray workpiece.Workpiece is after heating finishes, and when cooling, workpiece does not need to move, and quenchant is full of the endoporus of workpiece by main shaft inner chamber moment, realize quench cooled.
Main shaft and upper cover junction are in the both sides of circumference milling flat structure.Plane is transmitted rotary torque, and cylindrical surface plays a part location, guarantees workpiece energy high-precision rotary.
The utility model quenchant is full of inner hole of workpiece by hollow main shaft from the bottom to top and realizes coolingly, improves workpiece quenching cooling power under the prerequisite that does not affect workpiece rotary heating, has avoided the problem of inductor block dash, improves workpiece quenching quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, main shaft 3 middle parts are supported by bearing support 10, on main shaft 3, cover has the sealing socket 4 that is fixed on bearing support 10 tops, the lip-type packing 9 that in sealing socket 4 grooves, device seals main shaft 3, lip-type packing 9 is by compressing with the fixing sealing cover 5 of sealing socket 4, sealing cover 5 tops arrange the upper cover 6 being fixed on main shaft 3, main shaft 3 is in the both sides of circumference milling flat structure with upper cover 6 junctions, upper cover 6 tops arrange the positioning clamping fixture 7 being connected with main shaft 3 for supporting workpiece 8, synchronous pulley 2 is fixed in main shaft 3 bottoms, main shaft 3 is tubular shaft, in the endoporus of main shaft 3 tops in positioning clamping fixture 7, main shaft 3 top closure and have side opening to communicate with centre hole, main shaft 3 lower ends are passed through swivel joint 1 and are connected with the cooling duct of valve 11, valve 11 is selected magnetic valve or pneumavalve.When workpiece 8 heats, the moment of torsion that main shaft 3 transmits by synchronous pulley 2 drives positioning clamping fixture 7 and workpiece 8 to rotate, and keeps being normally tightly connected with cooling duct by swivel joint 1; When workpiece 8 is cooling, open valve 11, quenchant is full of workpiece 8 endoporus by 3 inner chamber moments of main shaft from the bottom to top and keeps flowing, and realizes fully cooling.
Claims (2)
1. an endoporus induction quenching refrigerating unit, main shaft middle part is supported by bearing support, on main shaft, cover has the sealing socket that is fixed on bearing support top, the lip-type packing of device to shaft seal in sealing socket groove, in lip-type packing, compress and have the sealing cover fixing with sealing socket, sealing cover top arranges the upper cover being fixed on main shaft, upper cover top is provided for the positioning clamping fixture of supporting workpiece, synchronous pulley is fixed in main shaft bottom, it is characterized in that: main shaft (3) is tubular shaft, in the endoporus of main shaft (3) top in positioning clamping fixture (7), main shaft (3) top closure and have side opening to communicate with centre hole, main shaft (3) lower end is passed through swivel joint (1) and is connected with the cooling duct of valve (11).
