Abstract
The invention relates to a rotary cylinder structure, which is arranged at the tail part of a machine tool. A hollow spindle is driven by a belt pulley at the tail end; a draw bar passes through the central through hole of the spindle; the head of the draw bar is connected with a chuck at the front part of the machine tool, and the tail end of the draw bar is connected with a cylinder; a cylinder piston can horizontally move in an air cavity between a front end housing and a back end housing; the front end housing of the cylinder is connected with a connection plate by an angular contact ball bearing; the connection plate is integrated with the belt pulley into a whole; the cylinder piston is connected with a draw bar shaft sleeve which is in close fit with the periphery of the draw bar by two pairs of plane bearings; and the tail part of the draw bar is provided with a draw bar cap which is used for installing the cylinder on the draw bar. The rotary cylinder structure is used to arrange the whole cylinder on the spindle, the draw bar and other rotatable parts by the angular contact ball bearing and plane bearings at two sides in a suspended mode, thus the whole cylinder does not rotate, thereby maintaining the stability of an air inlet and effectively preventing the cylinder from leaking gas; in addition, the rotary cylinder structure does not generate stress for a spindle bearing, thus avoiding the device from being damaged.
Description
Technical field
The present invention relates to field of machine tool equipment, in particular for the cylinder of main shaft gyration class lathe.
Background technology
Pipe fitting processing class lathe need adopt fixedly part to be processed of head chuck, and wherein a kind of clamp method is to adopt pull bar that the chuck of machine tool head is strained, in order to fixing axial workpiece.The structure of this lathe is hollow spindle normally, and pull bar is by the central through hole of main shaft, and rod head is connected with chuck, and afterbody is connected with the cylinder of lathe afterbody, and the axially-movable by cylinder piston realizes moving forward and backward, to loosen or to tighten up chuck.Belt pulley drive main shaft rotates at a high speed during lathe work, and chuck drives pull bar and also follows the main shaft rotation simultaneously, and adopt two kinds of schemes that the afterbody cylinder is set on lathe usually: a kind of is the cylinder transfer, and this moment, the air inlet of cylinder designed more complicated, and very easily gas leakage; Another kind is that cylinder and lathe bed are fixed, and this structure can cause main shaft bearing stressed, causes shorten the service life of main shaft bearing, and equipment dependability reduces.
Summary of the invention
The applicant is unreasonable at the method for attachment of above-mentioned existing lathe afterbody cylinder, transfer connects shortcomings such as easily gas leakage, fixedly connected easy damaged main shaft bearing, a kind of rotary cylinder structure rational in infrastructure is provided, thereby not only can guarantee gas circuit safely and effectively, and stressed reasonable, improve equipment dependability.
The technical solution adopted in the present invention is as follows:
A kind of rotary cylinder structure is arranged on the lathe afterbody, and hollow spindle is driven by the belt pulley of end, pull bar is by the central through hole of main shaft, rod head is connected with the chuck of lathe front portion, and afterbody is connected with cylinder, described cylinder piston can be in the air cavity between drive end bearing bracket and the rear end cap move left and right; The drive end bearing bracket of cylinder is connected with connecting plate by angular contact ball bearing, and described connecting plate and belt pulley connect as one; Cylinder piston is connected with the pull rod shaft cover that is a tight fit in the pull bar periphery by two secondary plane bearings, is provided with pull bar and cap is installed in cylinder on the pull bar at the pull bar afterbody.It is further characterized in that:
Lateral surface on the described rear end cap is fixed with at least one screw rod, is arranged with stop nut on the screw rod, and the limiting plate that is connected with cylinder piston is enclosed within on the screw rod, between rear end cap and stop nut.
The present invention is with angular contact ball bearing and plane bearing being erected at rotatable parts such as main shaft and pull bar on of suspending of entire cylinder by both sides, and transfer can not take place entire cylinder, so air inlet remains stablely, can effectively prevent cylinder leakage tester; And can not produce stress to main shaft bearing, cause equipment damage.
Description of drawings
Fig. 1 is a cutaway view of the present invention;
Fig. 2 is a stereogram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, rotary cylinder structure of the present invention is arranged on the lathe afterbody, hollow spindle 2 cooperates the belt pulley 3 by end to drive by keyway, pull bar 1 is by the central through hole of main shaft 2, pull bar 1 head is connected (not shown) with the chuck of lathe front portion, afterbody carries out floated the connection with cylinder, specifically, cylinder piston 7 is controlled down by the air inlet 15 and the gas circuit of air inlet 17, can be in by the drive end bearing bracket 6 of bolt 16 connections and the air cavity between the rear end cap 8 move left and right; The drive end bearing bracket 6 of cylinder is connected with connecting plate 4 by angular contact ball bearing 5, and connecting plate 4 connects as one with belt pulley 3; Cylinder piston 7 is connected with the pull bar axle sleeve 14 that is a tight fit in pull bar 1 periphery by two secondary plane bearings 12, is provided with pull bar and cap 13 is installed in said structure on the pull bar 1 at pull bar 1 afterbody.Be fixed with a plurality of spacing screw rods 11 on the lateral surface on the rear end cap 8, be arranged with stop nut 10 on screw rod 11, the limiting plate 9 that is connected with cylinder piston 7 is enclosed within on the screw rod 11, between rear end cap 8 and stop nut 10.
When machine tool of the present invention work is installed, connecting plate 4 transfers when belt pulley 3 rotates, pull bar and cap 13,14 transfers of pull bar axle sleeve when main shaft 2 rotates with pull bar 1, and entire cylinder, comprise drive end bearing bracket 6, cylinder piston 7 and the angular contact ball bearing 5 and being erected at these rotatable parts on that plane bearing 12 suspend of rear end cap 8 by both sides, owing to connect by bearing, entire cylinder can't transfer, therefore air inlet 15 and air inlet 17 remain fixingly, can effectively prevent cylinder leakage tester; And can not produce stress to main shaft bearing, cause the main shaft damage.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
