The novel cam indexing unit is characterized by comprising an index plate, check blocks, a thrust bearing, a crank, a positioning block, a positioning block slide seat, a roller and a cam, wherein the index plate is arranged on the thrust bearing and can rotate around the thrust bearing, a plurality of circular-arc-shaped notches are arranged on the outer edge of the index plate, and the number of the notches is decided according to the equant indexing number; a needed tool fixture and other components are mounted on the front face of the index plate, the plurality of check blocks are mounted on the back face, and the number of the check blocks is decided according to the equant indexing number; the crank is mounted on a machine frame on the back face of the indexing plate, the positioning block slide seat is mounted on an extending line of a connecting line of the indexing plate and a rotating shaft of the crank, the positioning block is fixedly mounted at one end, close to the indexing plate, of the positioning block slide seat, and the positioning block slide seat can slide freely on a slide way of the positioning block slide seat; and the roller is mounted at the other end of the positioning block slide seat, and the cam is mounted on the right side of the roller. The novel cam indexing unit has the advantages of being simple in structure, low in processing cost and high in indexing precision, and the indexing number can be changed freely, conveniently and quickly.
Description
Technical field
This novel practical relates to a kind of novel intermittent dispenser, the place that be mainly used in packing, indexing separator, the especially kludge of Printing Mechanical Industry, gilding press, silk-screen plant equipment etc. needs equation graduation.
Background technology
At present, general a kind of indexing separator is the globoidal cam dispenser on packing, the printing machinery, its structure by: volute conjugate cam, index dial, needle bearing form, its operation principle be by on the conjugate cam on the power shaft and the output shaft with the index dial of even distribution needle bearing without Vertical Meshing, the cam contour face gets the needle bearing that curved section orders about on the index dial and drives the index dial transposition, straightway makes index dial static, and self-locking.Generally, power shaft revolves and turns around, and output shaft is just finished a moving calibration process of stopping.Existing intermittence the globoidal cam dispenser building block: the volute conjugate cam, its cam track trace is complicated, processing difficulties, requirement on machining accuracy is higher, involves great expense and the equation graduation number can not change flexibly.
Summary of the invention
The purpose of this utility model is: provide a kind of use mechanism simple, cheap, and a kind of novel intermittent dispenser that the equation graduation number can freely change, exist the cam track trace complicated to solve prior art, processing difficulties, requirement on machining accuracy is higher, involves great expense and problem that the equation graduation number can not change flexibly.
Reaching the technical scheme that the purpose of this utility model takes is: a kind of novel intermittent dispenser, it is characterized in that: comprise index dial, block, thrust bearing, crank, locating piece, the locating piece slide, roller and cam, index dial is arranged on the thrust bearing, and can rotate around thrust bearing, described index dial outer rim is provided with several circular lances, otch quantity is determined by the equation graduation number, the parts such as required frock clamp are equipped with in described index dial front, several blocks are equipped with at the back side, the quantity of block is determined by isodisperse, on the frame of the described index dial back side crank is installed, the locating piece slide is installed on the extended line of described index dial and crankshaft line, the locating piece slide is installed with locating piece near index dial one end, the locating piece slide can be free to slide at its slideway, the described locating piece slide other end is equipped with roller, on the roller right side cam is installed.
Described locating piece slide is equipped with spring, so that roller is fitted with the cam outer rim all the time.
The effect of having a mind to that the utility model reaches is: adopt the utility model to reach simple in structure, processing cost is low, and indexing accuracy is high, and can conveniently change arbitrarily the beneficial effect of cutting apart the number of degrees.
Description of drawings
Fig. 1: structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of novel intermittent dispenser, it is characterized in that: comprise index dial 1, block 2, thrust bearing 3, crank 4, locating piece 5, locating piece slide 6, roller 7 and cam 8, index dial 1 is arranged on the thrust bearing 3, and can rotate around thrust bearing 3, described index dial 1 outer rim is provided with several circular lances 9, otch 9 quantity are determined by the equation graduation number, the parts such as required frock clamp are equipped with in described index dial 1 front, several blocks 2 are equipped with at the back side, the quantity of block 2 is determined by isodisperse, crank 4 is installed on described index dial 1 back side frame, its terminal roller 7 can intermittently change in the raceway that is comprised of two blocks 2 when crank 4 rotated, thereby stir index dial 1 intermittent rotary, on the extended line of described index dial 1 and crank 4 rotating shaft lines locating piece slide 6 is installed, locating piece slide 6 is installed with locating piece 5 near index dial 1 one ends, locating piece slide 6 can be free to slide at its slideway, described locating piece slide 6 other ends are equipped with roller 7, on roller 7 right sides cam 8 is installed, locating piece slide 6 is equipped with spring, so that roller 7 is fitted with cam 8 outer rims all the time.
Operation principle: described crank 4 is done gyration by motor-driven, the chain gear transmission of crank 4 and the identical number of teeth of cam 8 usefulness is to realize run-in synchronism, when changing over to, crank 4 terminal rollers promote index dial 1 rotation in the raceway that is formed by two blocks 2 until crank 4 terminal rollers, this stage, roller 7 contacts with cam 8 basic circle outer rims, and locating piece 5 separates with index dial 1 circular lance.Roller 7 just is positioned at cam rise initial point when crank 4 produces from the raceway that is comprised of two blocks 2, under being rotated further of crank 4, so that roller contacts with cam off-centre operation outer rim, thereby it is close to index dial 1 to promote locating piece slide 6, so that locating piece 5 just embeds the circular lance of index dial 1, loosening to prevent that index dial 1 from occuring, in whole rest stage far away, the rotating disk transfixion is in order to realize processing action to workpiece.Roller 7 is positioned at cam 8 backhaul starting points when crank 4 enters the raceway that another is comprised of two blocks 2 soon, under being rotated further of crank 4, so that roller contacts with the cam base circle outer rim, so that locating piece breaks away from index dial 1 circular lance, promoting again index dial 1 when crank 4 enters the raceway that is comprised of two blocks 2 fully rotates, so repeatedly, realized the interrupted division function, if need to change and cut apart five equilibrium quantity, only need index dial 1 is carried out calibration, the block that adds respective numbers gets final product, and need not to change other structures, and is not only convenient but also quick.
