Abstract
The utility model discloses a spindle head of a lathe, which has the structure that a driving shaft and a spindle connected with the driving shaft are arranged on the spindle head body. The utility model is characterized in that the outer part of the spindle is sleeved with a sliding sleeve via a bearing, the outer wall of the sliding sleeve is connected with a feed force arm, and the feed force arm is connected with a piston of a feed cylinder positioned at the outer side of the wall body of the sliding sleeve. The feed cylinder of the utility model can be a standard pneumatic or hydraulic cylinder, reduces the manufacturing difficulty of the spindle head, and reduces the manufacturing cost. In addition, the feed cylinder is arranged externally so as to be more convenient to maintain and replace.
Description
Technical field
The utility model relates to lathe, specifically a kind of machine tool chief axis head.
Background technology
The structure of the main tapping of existing hydraulic feed formula lathe is driving shaft to be installed and by the main shaft of this driving shaft driven rotary on the main tapping body, on the main tapping body, establish the hydraulic feed cylinder simultaneously, main shaft is connected in the feeding cylinder and with its piston and is connected, and drives main shaft by piston and does feed motion.Not only there is the defective of inconvenient maintenance in the main tapping of this structure, and causes feeding cylinder cylinder body bigger than normal because main shaft is connected in the feeding cylinder, must use the cylinder body of special processing and the topology requirement that piston just can be realized built-in main shaft.Because it can't use standarized component, therefore, make troubles for the processing and manufacturing of machine tool chief axis head and maintenance in the future.
The utility model content
The purpose of this utility model just provides a kind of main-shaft head structure that uses standarized component, offers convenience to give processing and manufacturing and maintenance in the future.
The utility model is achieved in that
This machine tool chief axis head, the main shaft that driving shaft is installed on the main tapping body and is connected with this driving shaft, its improvements are that main shaft is connected to sliding sleeve by bearing holder (housing, cover), tap into to the arm of force on the outer wall of sliding sleeve, and this feeding arm of force joins with the piston of the feeding cylinder that is positioned at the sliding sleeve wall body outside.
The utility model adopts this structure, need not the cross-under main shaft in the feeding cylinder, and therefore, the feeding cylinder can be selected the air pressure or the hydraulic cylinder of standard for use, thus, has not only reduced the manufacture difficulty of main tapping, has also reduced manufacturing cost.In addition, the feeding cylinder externally also make its maintenance, change convenient.
Under technique scheme, the utility model can be realized like this:
Spin by screw thread between the piston of the described feeding arm of force and described feeding cylinder.
The described feeding arm of force is two, is symmetricly set in the sliding sleeve outer wall.
Description of drawings
Fig. 1 is a side view of the present utility model.
Fig. 2 is the B-B cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1, shown in Figure 2, this machine tool chief axis head main tapping body 12 is fixed with motor 1, reduction gearing mechanism 2 and bearing block 6 on this main tapping body 12, and the output of reduction gearing mechanism 2 is connected to driving shaft 3, and driving shaft 3 is installed in the bearing block 6 by bearing 11.Main shaft 4 is installed in the sliding sleeve 5 by bearing 10.Driving shaft 3 is connected with main shaft 4 splines, realizes the main cutting running of main shaft 4.On the main tapping body outside the wall body of sliding sleeve 5 two feeding cylinders 7 are installed, feeding cylinder 7 can be cylinder or oil cylinder.Two feedings arm of force 8 is installed on sliding sleeve 5, and this feeding arm of force 8 joins with the piston of described feeding cylinder 7.A kind of embodiment preferably is as shown in Figure 2, and the piston rod end of the feeding arm of force 8 and feeding cylinder 7 is connected by threaded connector 9, thereby can regulate the supplying position of main shaft easily.The described feeding arm of force 8 can be provided with two, is symmetricly set in sliding sleeve 5 outer wall.
Operation principle of the present utility model is that motor 1 drives driving shaft 3 by reduction gearing mechanism 2, and driving shaft 3 drives main shaft 4 and does the main cutting running.Piston on the feeding cylinder 7 drives sliding sleeve 5 by the feeding arm of force and moves reciprocatingly, and the main shaft 4 that drives in the sliding sleeve 5 is done feed motion, realizes processing technologys such as boring, reaming, bore hole, fraising, planar shaping processing.
The utility model adopts external feeding cylinder, makes the designs simplification of main tapping, part standard, and then this main tapping is being kept under the prerequisite of the highest durability physical dimension and cost control in minimum.Be particularly suitable for holing at multiple operation building-block machine such as need, reaming, bore hole, fraising is used on the lathe of planar shaping processing etc.
Claims (3)
1. machine tool chief axis head, the main shaft (4) that driving shaft (3) is installed on main tapping body (12) and is connected with this driving shaft (3), it is characterized in that main shaft (4) is connected to sliding sleeve (5) by bearing holder (housing, cover), tap on the outer wall of sliding sleeve (5) to the arm of force (8), this feeding arm of force (8) joins with the piston of the feeding cylinder (7) that is positioned at the sliding sleeve wall body outside.
2. machine tool chief axis head according to claim 1 is characterized in that spinning by screw thread between the piston of the described feeding arm of force (8) and described feeding cylinder (7).
3. machine tool chief axis head according to claim 2 is characterized in that the described feeding arm of force (8) is two, is symmetricly set in sliding sleeve (5) outer wall.
