Description

A kind of automatic bar feeder with double fastener material group

Technical field

The present invention relates to mechanical equipment field, a kind of specific automatic bar feeder with double fastener material group.

Background technology

Automatic lathe or numerically controlled lathe need the automatic bar feeder mating with it automatically complete when being produced in batches At feeding, blanking and the work of feeding.Bar of the pile on automatic bar feeder rack falls into expects pipe by cutting agency In after, first have to be fixed by feeding clip mechanism, then push rod（It include the axis being connected with push rod and on axis Feed collet）It travels forward under the action of feeding motor, feed collet is socketed in bar end, completes the charging of bar.Charging is completed Afterwards, feeding clip mechanism unclamps, and bar can travel forward under the action of push rod, carries out feeding.Automatic bar feeder exists at present The conventional bar of clamping（4mm or more bars）When, generally use single clip mechanism to complete charging, but this kind of scheme is thinner for being clamped When bar, the following problem of generally existing：

1, thinner material stiffness is relatively low, is easily deformed, single clip mechanism bar meeting run-off the straight, more theoretical position when clamping bar Set leftward or rightward offset；

2, in order to ensure push rod can it is smooth by expects pipe, between push rod and expects pipe must there are the gaps of unilateral 0.5mm or more, and And push rod stress point is in rear end, and feed collet is in its front end, due to gravity, the reason of the practical center position of feed collet relative to push rod It is on the lower side by central axes, will also result in feed collet center and bar center to be held in this way, there are certain dislocation；

3, the collet of single clip structure is V-type on one side, is tooth form on one side, and bar enters negative area in V-type when clamping, is easy to lead Cause material bending；

Under the action of above several factors, more serious dislocation often occurs for the center of the center of feed collet and thin bar, At bar misalignment feed collet center, bar is just not easily accessed feed collet, if being mistaken for bar comes into feed collet, before push rod Into when will result in push rod and bar stuck shutdown occur.

Invention content

The shortcomings that the purpose of the present invention is overcoming the prior art and deficiency, provide it is a kind of it is simple in structure, bar deformation rate is low, The automatic bar feeder with double fastener material group of feeding efficiency can be effectively improved.

In order to achieve the above object, technical solution of the invention is：A kind of automatic bar feeding with double fastener material group Machine, including pedestal are provided with sliding rail on the pedestal, No.1 rack, the middle-end of the No.1 rack are fixed on the sliding rail It is installed with sliding steel bushing, is provided with plate cam on the outside of the sliding steel bushing, the plate cam is fixed by shaft In fixed seat, geometrical clamp group is installed in the fixed seat, the plate cam is provided with controllable close to the side of shaft The percussion hammer of geometrical clamp group opening and closing, it is characterised in that：The right end of the No.1 rack is fixedly connected with geosynclinal convex wheel plate, the fixed seat On be also equipped with movable folder group, the activity folder group is slidably connected at by bearing in geosynclinal convex wheel plate, the No.1 rack it is upper Side is provided with No. two racks, and the right end of No. two racks is fixedly connected with horizontal concrete chute, the activity folder group and horizontal concrete chute It is slidably connected.

The fixed holder and the clamping device of movable folder group include the left clamping jaw for setting up both sides separately and right clamping jaw, the left clamping jaw Pawl head is in U shape, is provided with " V " shape groove on the pawl head both sides side wall of left clamping jaw, is set in the pawl centriciput groove of left clamping jaw It is equipped with " V " shape convex block, the pawl head of the right clamping jaw is in " convex " font, is provided with and " V " shape convex block phase at the pawl head of right clamping jaw The " V " shape groove matched.

Floating clamp is installed in the upper groove surface of the activity folder group, limit pressure is provided with above the floating clamp Plate, floating clamp are internally provided with spring and plunger.

The geosynclinal convex wheel plate and fixed seat inner bottom surface parallel contact, the horizontal concrete chute and parallel contact above fixed seat, The fixed seat both sides are provided with side guide.

It is provided with microswitch in the mounting base of No. two racks, is installed on No. two racks of the microswitch side There is switch contact.

Main folder material motor and sub-folder material motor are installed, the main folder material motor is passed by chain and No.1 on the pedestal Moving gear is sequentially connected, and the sub-folder material motor is sequentially connected by chain and No. two transmission gears, the No.1 transmission gear It is meshed with No.1 rack, No. two transmission gears are meshed with No. two racks.

The side of the activity folder group is provided with clamping detection switch.

Compared with prior art, beneficial effects of the present invention are：

1, the present invention replaces traditional single clip material group structure using double fastener material group structure, and newly-increased activity material folding group can be by bar Front end effectively reduce the dislocation at feed collet center and bar center to be held, carry it is possible to prevente effectively from bar front end moves down High feeding effect；The separated clamping of feed collet and bar is realized by the combination of geometrical clamp group and movable folder group, and bar is sent into The feed collet of push rod front end is realized by the movement of movable folder group drive bar rather than comes in realize before pushing feed collet by push rod, stick The movement of material into feed collet is more stable, accurate.

2, in the present invention collet of movable folder group using double " V " font chi structures, it is left relative to original chuck structure With right pawl in the V-type protrusion of fit shapes inside clamping jaw, material bending becomes caused by can avoid jaw bite when fines is clamped Shape；The material of different-diameter is not had to readjust Clamping Center；In addition clamping jaw can compress dynamics by adjustment spring, can The automatic bar adapted within the scope of certain diameter, and the puzzlement of clamping jaw will be adjusted by eliminating replacement different size material.

3, the switch contact cooperation microswitch being arranged on No. two racks in the present invention, can effectively control No. two racks Distance is moved left and right, determines that bar tail end is inserted into the length of feed collet.

4, the present invention, can be follow-up according to detection case real-time control in the side of movable folder group setting clamping detection switch Operation improves working efficiency.
