Abstract
The external grinding machine has one tailstock sleeve set between the tailstock case and the tailstock shaft, and one hydraulic cylinder fixed through a piston rod to the tailstock sleeve. The hydraulic cylinder has cylinder body fixed onto the tailstock case, and the tailstock shaft is connected through the bearings to the tailstock sleeve capable of sliding axially inside the tailstock case. The ends of both the tailstock shaft and the headstock shaft have bidirectional thrust bearing installed. The headstock and tailstock fixing structures of the external grinding machine are used in the external grinding of great size and great specific weight conic and cylindrical workpieces, and have the features of high working quality, high safety, convenient operation, high work efficiency, etc.
Description
Technical field
The invention belongs to field of mechanical technique, relate to cylindrical grinder, particularly the grinding machine headstock, the tailstock clamping structure of the circular cone of large scale, big proportion/cylindrical work processing usefulness.
Background technology
Heavy circular cone/cylindrical work, as hard alloy top hammer, the processing of its cylindrical can only be adopted general cylindrical grinder processing at present, and clamping workpiece is to rely on the anchor clamps that are installed in the headstock and the initial tension of spring on the tailstock spindle to withstand.Top hammer series hard alloy workpiece is than great, and appearance and size is also increasing, and substance has reached 75kg.Because the initial tension of spring in the tailstock is restricted,, can cause the axial force of the headstock to strengthen, and the headstock does not have axial force control device or structure, and the main shaft bearing of the headstock is damaged soon, maintenance capacity is big if strengthen the spring in the tailstock; And pressure will overcome deadweight, processing resistance and feed force simultaneously, and therefore general cylindrical grinder can't guarantee to push up the machining accuracy of hammer series hard alloy.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of cylindrical grinder is provided, and the clamping structure of its headstock and tailstock is used for the circular cone/cylindrical work Cylindrical Grinding Processes of large scale, big proportion, can not only guarantee crudy, and have characteristics such as safe, easy to operate, operating efficiency height.
Cylindrical grinder of the present invention comprises the headstock, tailstock, lathe bed and bistrique; Described tailstock comprises tailstock spindle in the tailstock case, tailstock case, places the top of tailstock spindle front end; The described headstock comprises headstock case, is supported on headstock spindle on the headstock case, places the driving gear set on the headstock spindle between headstock fore bearing and the back headstock bearing by headstock fore bearing and headstock rear bearing; It is characterized in that: its also described tailstock that comprises between tailstock case and the tailstock spindle, and the hydraulic cylinder of fixedlying connected with described tailstock spindle sleeve by piston rod; Described hydraulic cylinder is fixed on the tailstock case by its cylinder body, described tailstock spindle by tailstock fore bearing and tailstock rear bearing with can be in the tailstock case in axial sliding the tailstock spindle sleeve be connected.
As improvement, described grinding machine also comprises the bidirectional stress thrust bearing that is installed on the tailstock spindle end.
As improvement, described grinding machine also comprises the bidirectional stress thrust bearing in the cylindrical shell that is installed in headstock the tip of the axis and places sealing, and cylindrical shell is coaxial and fix with headstock case with headstock spindle.
Because tailstock has partly adopted hydraulic cylinder, substituted the preloading spring in the general cylindrical grinder tailstock, not only pressure increases, and can steplessly adjust, can be easily for the workpiece centering provide low hydraulic pressure, provide high hydraulic pressure for work holds out against, promptly according to the needs of workpiece processing and loading clamp, tailstock can drive tailstock spindle and stretch together, contracts under the control of hydraulic cylinder, guarantee that clamping is reliable in the workpiece grinding process, guaranteed machining accuracy and safety.Simultaneously partly set up the bidirectional stress thrust bearing, eliminate of the influence of huge axial force respectively, improved machining accuracy tailstock spindle, headstock spindle running accuracy at the tailstock and the headstock, also prolonged axle service life, improved the lathe rigidity.New grinding machine structure makes easy to operately, and operating efficiency is improved.
Description of drawings
Fig. 1 is the headstock, the tailstock structural representation of grinding machine of the present invention.
The specific embodiment
As shown in Figure 1, cylindrical grinder of the present invention mainly comprises headstock A, tailstock B, lathe bed C and bistrique D.Tailstock B mainly comprises tailstock case 7, tailstock spindle 8 and top 12; Tailstock spindle 8 is in tailstock case 7, and top 12 place tailstock spindle 8 front ends.Headstock A mainly comprises headstock case 1, headstock spindle 2 and driving gear set 4; Headstock spindle 2 is supported on the headstock case 1 by headstock fore bearing 31 and headstock rear bearing 32, and driving gear set 4 is installed on the headstock spindle 2, between the forward and backward bearing 31,32 of the headstock.Design has tailstock 9 between tailstock case 7 and the tailstock spindle 8, can axially slide in tailstock case 7, and tailstock spindle 8 is connected with tailstock spindle sleeve 12 with tailstock rear bearing 92 by tailstock fore bearing 91.Hydraulic cylinder 11 is fixed on the tailstock case 7 by its cylinder body 111, and its piston rod 112 is fixedlyed connected with tailstock spindle sleeve 9.
Because tailstock has partly adopted hydraulic cylinder, substituted the preloading spring in the general cylindrical grinder tailstock, not only pressure increases, and can steplessly adjust, can low hydraulic pressure be provided, provide high hydraulic pressure for the workpiece centering easily for work holds out against, promptly according to the needs of workpiece processing and loading clamp, tailstock can drive tailstock spindle and stretch together, contracts under the control of hydraulic cylinder, do not guarantee in big proportion, the large-sized workpiece grinding process clamping reliably, can not produce micro displacement, thus guaranteed safe, improved machining accuracy.
At tailstock spindle 8 ends bidirectional stress thrust bearing 10 is installed; On headstock spindle 2 ends bidirectional stress thrust bearing 5 has been installed, bearing 5 is positioned at cylindrical shell 6, and cylindrical shell 6 and headstock spindle be 2 coaxial, be fixed on headstock case 1, adopts end cap seal.Bidirectional stress thrust bearing 10 and 5 setting, tailstock spindle under the responsive to axial force also can high accuracy be rotated, and the axial force that has produced when having eliminated grinding has improved the lathe rigidity to the influence of tailstock spindle, headstock spindle running accuracy, further improve machining accuracy, prolonged the service life of axle.Hydraulic structure makes piece-holder, it is easy to operate to hold out against, and operating efficiency is improved.
