The device has the advantage of simple structure.

Description

The machining bearing lasso loop back rotatable hopper

The utility model relates to cool working machinery, refers in particular to a kind of automatic charging device that is used for grinding machine or super lapping machine processing miniature bearing lasso.

Up to now, maximum outside diameter D≤φ 26mm adds man-hour to the miniature bearing lasso of minimum outer diameter D=φ 2.5mm on grinding machine or super lapping machine, the material-uploading style that is adopted: one is manual material loading, and its shortcoming is: labour intensity is big, and capacity rating is low; Two for adopting the automatic charging of oscillatory type hopper, and its shortcoming is: oscillatory type hopper oad is bigger, makes whole machine tool structure volume seem huge; During the work of oscillatory type hopper, vibration noise is big, has a strong impact on production environment, hinders operator's health; The fault rate height runs counter to the requirement of miniature bearing High-efficient Production.

The purpose of this utility model is the rotatable hopper that loops back of a kind of machining bearing lasso of design, with simplified structure, raises the efficiency, and improves workman's labor condition.

Its main technical schemes comprises feed bin and the blanking mechanism thereof that is installed on the pedestal, it is characterized in that in described blanking mechanism, the guide disk is positioned at the bottom of feed bin, the middle part is fastenedly connected transmission shaft in its lower section, and utilize transmission shaft and bearing to be connected with the base plate of feed bin, the lower end of transmission shaft is connected with actuating device on being installed in pedestal, it is flanged cylindric that the bottom of guide disk is, the upper surface of flange is open circuited inclined-plane, form wedge, on the flange of wedge gap, be provided with the through hole of up/down perforation, the material-dropping hole and the material guide hole that can be communicated with through hole arranged at the base plate and the corresponding site of pedestal.

Its another feature is that to be the center be vertex on the top of guide disk, and with radial to the edge approximate circle taper of height or approximate hemispherical that successively decreases.

Advantages such as this device has compact conformation, and material loading speed is fast, and the efficient height moves accurately and reliably, and work noise is extremely low.

This automatic charging device is fit to grinding machine or super lapping machine (this paper is referred to as lathe) is processed maximum outside diameter D≤φ 26mm to minimum outer diameter D=φ 2.5mm, the usefulness of the miniature bearing lasso of length-diameter ratio L/D＜1 (seeing accompanying drawing 3) and the automatic charging of rotary type thing when (this paper is referred to as workpiece) of similar dimensions thereof.

Fig. 1 is a constructional drawing of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the workpiece to be processed constructional drawing.

As shown in the figure: this automatic charging device mainly is made up of with through hole 11 feed bin 1, guide disk 2, wedge 3, flange 4, transmission shaft 5, base plate 6, actuating device 7, pedestal 8, material guide hole 9, material-dropping hole 10.

The rounded bottom surface circle centre position of the cylindrical feed bin 1 of interior profile and edge have a material-dropping hole 10 that is used to that the through hole of transmission shaft 5 is installed and is used for blanking respectively.The top of guide disk 2 be the center be vertex and with radial to around the approximate circle taper of height or approximate hemispherical that successively decreases; The bottom of guide disk 2 is the cylindric of flanged pin 3; The upper surface of flange 3 is the inclined-plane of open circuited tool certain angle, thereby forms wedge 3; On the flange 3 between the non-coherent place, the two ends of wedge 3, be provided with the through hole 11 of up/down perforation.Feed bin 1 is fixed on the pedestal 8 with the base plate 6 of its lower housing portion; Guide disk 2 is the level of state with its lower surface and places in the feed bin 1 on the circular bottom plate 6, and the through hole 11 on the flange 3 of guide disk 2 is just matching with the material-dropping hole 10 at feed bin 1 rounded bottom surface edge, and material-dropping hole 10 is communicated with material guide hole 10 on the pedestal 8.The actuating device 7 that is fixed on the pedestal 8 is connected with the lower end of transmission shaft 5; The through hole that feed bin 1 bottom is passed in the upper end of transmission shaft 5 is fixedly connected on the center of circle, lower surface of guide disk 2.

This automatic charging device working process is: actuating device 7 drives the reciprocating rotating that guide disk 2 is made certain angle by transmission shaft 5; Under the centrifugal action that guide disk 2 turns round and produced, originally the workpiece that was unordered shape at random in the feed bin 1 with self end face in vertical state below feed bin 1 internal perisporium is arranged in wedge 3, be rolling gesture from high to lower, and workpiece be pushed to the through hole on the flange of guide disk 2 by the thrust that guide disk 2 revolution is produced wedge 3; When the material-dropping hole that returns back to through hole on its flange and feed bin 1 rounded bottom surface edge when guide disk 2 coincided again, workpiece just relied on self gravitation to fall into the material road by feed bin 1 bottom edge material-dropping hole and material guide hole, is in state to be processed; So circulate repeatedly, thereby realize automatic charging.

This automatic charging device, by being connected and including in the control system of lathe with signal transmitter, can be according to the mode of operation of lathe, realize auto-stop, recover the material loading function automatically.
