Description
Technical field
The utility model relates to a kind of bar processing machine tool field, is a kind of specifically and the matching used steel bar automatic feeding of lathe mechanism.
Background technology
At present, the matching used steel bar automatic feeding of lathe mechanism in the prior art, its structure is generally in the bar and is placed in the feeding rod, and an end of feeding rod stretches in rotary cylinder and the main spindle box, and be provided with feeding folder at this end and chew, the other end is connected with oil hydraulic cylinder by connecting plate.Usually feeding rod is shorter, is overlapping 1/3 of bar total length in, and all the other length are by plastic cement pipe support, and the plastic cement pipe is fixed by several bracing frames that combined by the vee-block that cooperates in pairs up and down.Mechanism by feeding folder chew, main spindle box, being used of rotary cylinder and oil hydraulic cylinder realizes that bar press the effect of predetermined length stepping conveying.But, in the use of reality, there are following two aspect shortcomings in the bar feed mechanism of this structure, first: owing to be placed in the plastic cement pipe in the bar, and the plastic cement pipe is fixed on the bracing frame, and the length that bar stretches out outside the main spindle box is longer, when in the plastic cement pipe, rotating under the drive of bar at main spindle box, because centrifugal action, the bar that rotates also can be swung simultaneously, and the plastic cement pipe is produced bump, causes bigger noise, and bump can cause to a certain degree wearing and tearing, the service life of having reduced the plastic cement pipe to bar and plastic cement pipe; Second: because stay pipe is by several bracing frame fixed supports, belonging to fulcrum supports, the place of rectangular bar beyond fulcrum is because the gravity effect, have tenesmus buckling phenomenon to a certain degree, the feeding folder is chewed the twist and warping power effect that produces, influence the action that the feeding folder is chewed, mechanism's pushing precision is lower, and has quickened the wear process that the feeding folder is chewed.Therefore, adopt the feed mechanism of this kind structure, its operating noise is big, and pushing precision is lower.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the steel bar automatic feeding that a kind of noise is little, pushing precision is high mechanism is provided.
Goal of the invention of the present utility model is achieved in that a kind of steel bar automatic feeding mechanism, comprise main spindle box, oil hydraulic cylinder, the delivery sheet that is connected with oil hydraulic cylinder and be used to contain the feeding rod of bar, main spindle box one side is provided with rotary cylinder, feeding rod passes rotary cylinder and stretches in the main spindle box, and being provided with feeding folder at the discharging opening of feeding rod chews, be provided with a pull bar between main spindle box and the feeding rod, the two ends of pull bar are located at spring clip in the main spindle box with rotary cylinder and respectively and are chewed and be connected, it is characterized in that: the exposed junction of feeding rod is provided with the feeding rod sheath that is connected with delivery sheet, be provided with the supporting member that feeding rod is rotated around feeding rod sheath axis in the feeding rod sheath, be provided with axial limiting spare near feeding rod sheath end on the feeding rod.
Described supporting member is a rolling bearing.
Described axial limiting spare is a locking nut.
Described feeding rod sheath two ends are respectively equipped with the support slide.
The utility model improves the steel bar automatic feeding mechanism of prior art, end at feeding rod is provided with the feeding rod sheath that is connected with delivery sheet, be provided with rolling bearing between feeding rod sheath and the feeding rod, feeding rod and bar can rotate in the bearing inter-sync, avoided the collision of bar to feeding rod, eliminate noise greatly, reduced mutual friction mutually between bar and the feeding rod, the service life of having improved feeding rod.Simultaneously, be to rotate synchronously between feeding rod and the bar, bar can not form the tenesmus buckling phenomenon in feeding rod, the feeding folder is chewed avoided twisting and warping the power effect, improve the pushing precision of mechanism, and slowed down the wear process that the feeding folder is chewed, improved the actual serviceability of mechanism.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, steel bar automatic feeding of the present utility model mechanism, comprise main spindle box 1, oil hydraulic cylinder 2, the delivery sheet 3 that is connected with oil hydraulic cylinder 2 and be used to contain the feeding rod 5 of bar 4, main spindle box 1 one sides are provided with rotary cylinder 6, feeding rod 5 passes rotary cylinder 6 and stretches in the main spindle box 1, and be provided with feeding folder at the discharging opening of feeding rod 5 and chew 7, and the length of feeding rod 5 is suitable substantially with bar to be processed 4 length, it is more smaller than bar 4 usually that the feeding folder is chewed 7 internal diameters, and a bit of opening is arranged usually at the feed end of feeding rod 5, so that bar 4 conveniently put in and relative fixed in the cavity of feeding rod 5, and be provided with a pull bar 8 between main spindle box 1 and the feeding rod 5, the two ends of pull bar 8 are chewed 9 with the spring clip in rotary cylinder 6 and is located at main spindle box 1 respectively and are connected, simultaneously, exposed parts at feeding rod 5 is provided with feeding rod sheath 10, feeding rod sheath 10 is fixedlyed connected with delivery sheet 3, feeding rod sheath 10 two ends are respectively equipped with supports slide 13, and in feeding rod sheath 10, be provided with the supporting member 11 that is used to support feeding rod 5, supporting member 11 is a rolling bearing, feeding rod 5 can rotate around feeding rod sheath 10 axis by this supporting member 11, be provided with axial limiting spare 12 near feeding rod sheath 10 ends on the feeding rod 5, this axial limiting spare 12 is a locking nut.
When mechanism works; bar 4 is put in the main spindle box 1 by feeding rod sheath 10 by the left of feeding rod 5 always; and stretch out certain-length at main spindle box 1 front end; rotary cylinder 6 is moved to the left pull bar 8; driving spring clip chews 9 actions and clamps bar 4; then bar 4 drives rotation by the rotating mechanism of main spindle box 1; bar 4 is processed and cut off to knife rest on the lathe by the program of setting to bar 4; rotary cylinder 6 makes pull bar 8 and spring clip chew 9 to move forward again then; spring clip is chewed 9 and is unclamped bar 4; simultaneously; oil hydraulic cylinder 2 actions promote delivery sheet 3 together with 10 actions of feeding protective sleeve, and the bearing promotion locking nut in the feeding protective sleeve 10 makes feeding rod 5 drive the feeding folder and chews 7 actions; bar 4 feeding folder chew 7 clamping and with the stiction effect of feeding rod 5 under move forward predetermined length, realize the feeding process.And then, rotary cylinder 6 spurs pull bar 8 left, and spring clip is chewed 9 and moved to left, and clamps bar 4 once more, and then oil hydraulic cylinder 2 actions promote feeding rods 5 and feeding folder by delivery sheet 3 and chew 7 and move to left and reset.The utility model has been avoided the collision of 4 pairs of feeding rods 5 of bar, has eliminated noise greatly, has reduced mutual friction mutually between bar 4 and the feeding rod 5, the service life of having improved feeding rod 5.Simultaneously, be to rotate synchronously between feeding rod 5 and the bar 4, bar 4 can not form the tenesmus buckling phenomenon 5 li of feeding rods, make the feeding folder chew 7 and avoid twisting and warping the power effect, improve the pushing precision of mechanism, and slowed down the feeding folder and chewed 7 wear process, improved the actual serviceability of mechanism.
