Above-mentioned heavy-duty engine lathe tailstock according to the utility model technical scheme forms moving sets between the upper body body of barrel of tail stock and tailstock, realizes the flexible of tailstock through the hydraulic cylinder of drive sleeve action again, and then top tight workpiece or unload workpiece, and action is quick; And can realize the uniformity of pressure through the pressure of setting up hydraulic circuit, thereby realize the reliability of action.
The parts that above-mentioned heavy-duty engine lathe tailstock, said lower body are used for being connected with the body of lathe bed are one group of synchronously driven hydraulic locking assembly.
Above-mentioned heavy-duty engine lathe tailstock, said hydraulic locking assembly comprise under the user mode and cooperating with the pressing plate spacing to said lower body with bed ways, and be installed on the said lower body and piston rod connects the lower body hydraulic cylinder of said pressing plate.
Above-mentioned heavy-duty engine lathe tailstock, said hydraulic locking assembly has four, divides four jiaos that occupy tailstock.
Above-mentioned heavy-duty engine lathe tailstock, said lower body also are provided with vertical slotting key and driving mechanism thereof, with in working order down to tailstock form retreat spacing.
Above-mentioned heavy-duty engine lathe tailstock, said hydraulic cylinder cooperates with said seat hole axis hole, and the seat portion of this hydraulic cylinder is packed in the rear end, upper body through bolt.
Above-mentioned heavy-duty engine lathe tailstock, said tailstock spindle is connected through cylinder roller bearing with said barrel of tail stock.
Description of drawings
Fig. 1 is the structural representation according to a kind of heavy-duty engine lathe tailstock of the utility model.
Fig. 2 is the user mode figure of a kind of heavy-duty engine lathe tailstock on lathe.
Among the figure: 1. upper body, 2. lower body, 3. barrel of tail stock, 4. bearing, 5. tailstock spindle, 6. screw, 7. hydraulic cylinder, 8. piston rod is 9. gone up the lower body attachment screw, 10. inserts key, 11. lower body piston cylinders, 12. piston rods, 13. pressing plates, 14, handle, 15 Hydraulic Stations.
The specific embodiment
With reference to explanation accompanying drawing 1, a kind of heavy-duty engine lathe tailstock comprises the upper body 1 that is provided with barrel of tail stock 3 and as the lower body 2 to carry said upper body of tailstock base; Tailstock spindle 5 wherein is installed in the barrel of tail stock, and this is the traditional structure of tailstock, and upper body 1 in most cases is an integrative-structure with lower body 2; Casting; In order to overhaul conveniently, upper body and lower body difference moulding in some cases, and then connect into integral body.Connect into the whole general bolt that adopts and connect, the last lower body attachment screw 9 that passes through shown in accompanying drawing 1 connects easy disassembly.
The function of barrel of tail stock 3 because of realizing stretching generally and between the seat hole on the upper body forms moving sets, moves axially along the seat hole through secondary this barrel of tail stock that drives of self-locking thread usually.According to the utility model; Said barrel of tail stock 3 also be adopt be formed on the upper body on a hole axle sleeve cooperate and form moving sets; On the upper body, be fixed with a hydraulic cylinder 7 coaxial with said barrel of tail stock then, the piston rod of this hydraulic cylinder is bonded on the afterbody of said barrel of tail stock.Just can satisfy the flexible specification requirement of tailstock through the adjustment of hydraulic cylinder,
Tailstock generally is unworthy of independently hydraulic system, need overlap hydraulic system with one with the turner, the Hydraulic Station shown in accompanying drawing 2, and the corresponding hydraulic circuit of dispensing is in said hydraulic cylinder 7.
As further selection, the parts that said lower body 2 is used for being connected with the body of lathe bed are one group of synchronously driven hydraulic locking assembly.Hydraulic locking apparatus is more is applied in mechanical field; Technology is relatively ripe; Its setting on it also has the corresponding structure basis; The lathe bed structure that the screw-threaded coupling mechanism that is before adopted is relied on can be adopted by the hydraulic locking assembly just, does not need the extra lathe bed design of carrying out.
For the locking of tailstock come down to that tailstock makes progress spacing and backward spacing, what make progress is spacing for depending on frame for movement against formation, and the basis is bed ways.So said hydraulic locking assembly comprises under the user mode pressing plate 13 that cooperates with bed ways with spacing to said lower body 2, and is installed on the said lower body and piston rod connects the lower body hydraulic cylinder of said pressing plate.Thereby, just can control the locking of tailstock through the extension and contraction control of lower body hydraulic cylinder, coupling mechanism force can be carried out regulation through the setting of lower body hydraulic cylinder hydraulic circuit hydraulic fluid pressure equally, satisfies and locks fast and reliably or release.
One group of said hydraulic locking assembly can only have one or even number, and such as two or four, preferable selection is four, divides four jiaos that occupy tailstock, and reliability is relatively good.Too much can't increase the reliability of locking, can increase cost on the contrary, two also can be satisfied instructions for use fully in fact.
Advance assembly with said hydraulic lock and be used, said lower body also is provided with vertical slotting key 10 and driving mechanism thereof, with in working order down to tailstock form retreat spacing.Like the handle among Fig. 1 14,, operate also more convenient through said slotting key 10 actions of this handle drives.
For simplified structure, referring to accompanying drawing 1 right-hand member, said hydraulic cylinder 7 cooperates with said seat hole axis hole, and the seat portion of this hydraulic cylinder is packed in the rear end, upper body through bolt.
Tailstock spindle must be able to rotate; Therefore; The general mounting structure of tailstock spindle is a said tailstock spindle 5 and said barrel of tail stock 3 is connected to form revolute pair through bearing, and preferably, affiliated bearing preferably uses cylinder roller bearing to connect; Both satisfy the high speed requirement of rotating, also satisfied the load requirement of bearing.
