Abstract
A continuous transmission device of a small conical workpiece comprises a frame. The frame is provided with a guide pipe for transmitting the conical workpiece, and a cylindrical cam spirally consisting of a cylindrical convex body and a cam screw; the center of the cam body is provided with a transmission shaft; the side wall of the guide pipe is provided with a long trough gap; the cam screw extending into the gap of the guide pipe is partly contacted and engaged with the end surface of the conical workpiece. The continuous transmission device provided by the utility model can be transmitted in vertical direction and horizontal direction as adopting the rotation of the cylindrical cam as the power for driving the workpiece to continuously motion, the device has simple structure, easy production and maintenance and is convenient to be practically generalized and applied.
Description
Technical field
The utility model relates to workpiece feeding in continuous material and transmission field.
Background technology
Using self-acting lathe and apparatus for production line to carry out in the quantity-produced practical application, usually need small-sized coniform workpiece is carried out along conduit the continuous transmission of certain distance.The mode that solves this type of problem at present mainly contains: rely on gravity for transport merely; The axial pressure transmission; Several modes such as friction wheel extruding traction transmission.
More than in the various forms of Cai Yonging, all there is certain limitation part.For example, rely on gravity to transmit merely, advantage is to import without any need for power, if but workpiece deadweight very light (as Plastic Parts), or vertical space then can't carry out normal transmission when being restricted, and this kind mode is difficult to realize the horizontal direction transmission of workpiece.Adopt the simple axle center type of transmission of exerting pressure can carry out the transmission of any direction, shortcoming is to realize difficulty of the continuous transfer ratio of workpiece, generally needs the process of extra filling workpiece, influences machine single-piece work efficiency.Adopt friction wheel extruding traction transmission can overcome the deficiency of top form, but it has following shortcoming: because the contact surface between friction wheel and the workpiece is less, bigger if desired transmit force then can make the contact stress between friction wheel and the workpiece bigger, makes the very fast damage of friction wheel.And owing to above reason, this kind mode is not suitable for the transmission of thin-wall workpiece.
Summary of the invention
The purpose of this utility model just provides a kind of continuous transmitting device of small-sized coniform workpiece, and this device vertical direction, horizontal direction all can be transmitted, and simple in structure, makes and safeguards easily, is convenient to apply in practice.
For realizing above purpose, the utility model is by the following technical solutions: the continuous transmitting device of this small-sized coniform workpiece comprises: frame, the conduit used of the coniform workpiece of transmission is housed on the frame, the cylindrical cam of being made up of cylindric cam body and cam spiral is housed, transmission shaft is established at the center of cam body, the sidewall of conduit has the elongate slots breach, and the cam spiral that stretches into the conduit indentation, there contacts with the end face part of coniform workpiece, also engagement.
The spiral number of turns on the described cam body is between 1 thoughtful 2 weeks.
The utility model with the rotation of cylindrical cam as the power that drives the workpiece continuous movement, workpiece in conduit with small end preceding, big end after the mode proper alignment, have the long trough breach on the catheter wall, the spiral part of cylindrical cam stretches into the end face part of conduit contact workpiece from indentation, there, be the part of large end face near the edge, thus the engagement system between similar single start worm of formation and tooth bar between workpiece on the elevation profile and the cam.Because the axial direction of cam is fixed, when cam rotation, because the gearing of similar worm spiral, the tapered workpiece quilt of the proper alignment of similar tooth bar promptly drives along duct direction along its axis direction.Workpiece is put into from the conduit top continuously, and cam turns round continuously, can reach the purpose of continuous transmission workpiece.
Cylindrical cam can each symmetry be provided with in the conduit both sides, also can be only in the one-sided setting of conduit.The benefit that is symmetrical arranged mode is to make workpiece along uniaxial force, and duct wall portion is not produced pressure, thereby friction drag is little, but requires the running of two cylindrical cams synchronously, and manufacturing dimension is comparatively accurately consistent, otherwise the out of reach workpiece is along the situation of uniaxial force.One-sided set-up mode makes the workpiece eccentric force, thereby workpiece and duct wall generation friction drag, and driving efficiency is lower than symmetrical set-up mode, but mechanism is simple, and the size accuracy of manufacture is less demanding.
Advantage of the present invention is: the shortcoming and the limitation that can overcome prior art, because the transmission of adopting cylindrical cam is as the power that drives the workpiece continuous movement, but vertical direction, horizontal direction transmission workpiece, applied range, and it is simple in structure, manufacturing and maintenance are convenient to apply in practice easily.
Description of drawings
Fig. 1 be the one-sided set-up mode of the utility model an embodiment (along vertically again level send workpiece).
Fig. 2 is Figure 1A-A section-drawing (initial condition that workpiece contacts with the cam spiral part).
Fig. 3 is another embodiment (vertically sending workpiece) of the one-sided set-up mode of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, Fig. 2, Fig. 3, transmitting device is made up of conduit 2, frame 5, cam body 7, cam spiral 6 and transmission shaft 8 etc.Conduit 2 is fixed on the frame 5 by screw 3, and transmission shaft 8 and cam body 7 and cam spiral 6 connect as one by key, and two ends are equipped with the bearing 4 that can bear axial force, and integral installation can drive cam body 7 and 6 runnings of cam spiral on frame 5.
