Description
Technical field
The utility model relates to a kind of push rod positioner, particularly relates to a kind of determining than lever drive formula push rod positioner by lever transmission.
Background technology
Product orientation is very common in commercial Application, when such as a certain product and other parts being carried out pressing, just need product orientation, a kind of pushrod advances that uses is needed to reach location object detent mechanism to withstand product in some cases, if this detent mechanism adopts manual operation, push rod can swing and cause location inaccurate, affect the quality of pressing product, and manual operation labour intensity is large.
The application for a patent for invention that application number is " 201410182403.2 " discloses a kind of detent mechanism, its lift cylinder fixed head is arranged on the bottom of base plate, cam lift cylinder is arranged on lift cylinder fixed head, and the elevating lever of cam lift cylinder links together through base plate and cam; Base plate is installed with cam baffle plate, cam baffle plate is provided with slide rail, and cam is provided with slide plate, and slide rail and slide plate are installed togather; Push rod gripper shoe is arranged on base plate, and push rod gripper shoe is provided with linear bearing, and push rod left end is provided with roller by rotating shaft, and right part passes from linear bearing, base plate is also installed with the block that anti-throw-out lever swings; The action of cam lift cylinder, rises cam along the slide rail on cam baffle plate, cam and roller contact, and roller rolls and push rod moved forward along linear bearing direction, withstands product and reaches the day of location.
The detent mechanism of above-mentioned patent application, cam lift cylinder is arranged on below base plate, takes up room large; The motive force of cam lift cylinder realizes pushing rolling wheels after 90 ° of break-ins of thrust by the inclined-plane of cam, thus promotes push rod and move, so thrust can reduce, push rod formation can be shortened, the final promotion effect realized can be had a greatly reduced quality.
Utility model content
The purpose of this utility model is just to provide to solve the problem that a kind of power slippages is little, fixed than lever drive formula push rod positioner by lever transmission of compact conformation.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of fixed than lever drive formula push rod positioner, comprise push rod, base plate, cylinder and push rod gripper shoe, described push rod gripper shoe is installed on described base plate, described push rod is installed in described push rod gripper shoe by linear bearing, describedly fixed also comprise lever than lever drive formula push rod positioner, the stage casing of described lever is installed on lever mounting bracket by pivot shaft, described lever mounting bracket is installed on described base plate, described base plate is also provided with cylinder mount pad, one end of described cylinder is articulated with on described cylinder mount pad, the piston rod of the described cylinder other end and the lower end of described lever hinged, the upper end of described lever is provided with the mandrel vertical with described lever axial direction, the termination of described push rod is provided with the strip through-hole of vertical direction, the width of described strip through-hole is slightly larger than the external diameter of described mandrel, the termination of described push rod is set on described mandrel by described strip through-hole also can rotate, described mandrel can move up and down in described strip through-hole.
In said structure, lever plays the effect of rotary drive, passes to push rod after the power of cylinder is changed direction, drives push rod to move the object reached product orientation; The mandrel of lever coordinates with the strip through-hole of push rod, realizes the rotation of lever relative to push rod on the one hand, realizes the height changing lever upper end when the inconvenience of push rod height on the other hand, and does not affect the promotion of lever upper end to push rod simultaneously.
Take volume in order to what reduce this device as far as possible, described cylinder mount pad is between described push rod gripper shoe and described lever mounting bracket and near described push rod gripper shoe.
The beneficial effects of the utility model are:
The utility model take cylinder as power part, promote push rod by lever drive to move, because the power loss of lever drive is little, and lever two ends power input and output ratio can be determined by selecting when designing the position of pivot shaft, corresponding change lever two ends displacement input and output ratio, thus the best collocation demand realizing push rod thrust and displacement; In addition, due to lever driving arrangement and all can be arranged on the same side of lever by dynamic equipment, so whole device takes up room little, be convenient to install.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-Figure 4, described in the utility modelly fixed comprise push rod 5 than lever drive formula push rod positioner, base plate 13, cylinder 11, push rod gripper shoe 6 and lever 4, push rod gripper shoe 6 is installed on base plate 13, push rod 5 is installed in push rod gripper shoe 6 by linear bearing 7, the stage casing of lever 4 is installed on lever mounting bracket 9 by pivot shaft 8, lever mounting bracket 9 is installed on base plate 13, base plate 13 is also provided with cylinder mount pad 12 between push rod gripper shoe 6 and lever mounting bracket 9 and near the position of push rod gripper shoe 6, one end of cylinder 11 is articulated with on cylinder mount pad 12, the piston rod 10 of cylinder 11 other end is hinged with the lower end of lever 4, the upper end of lever 4 is provided with the mandrel 3 vertical with the axial direction of lever 4, the termination 1 of push rod 5 is provided with the strip through-hole 2 of vertical direction, the width of strip through-hole 2 is slightly larger than the external diameter of mandrel 3, the termination 1 of push rod 5 is set on mandrel 3 by strip through-hole 2 also can rotate, mandrel 3 can move up and down in strip through-hole 2.
For the ease of installing, the termination 1 of push rod 5 is plate shaped, different from the other parts shape of push rod 5, so the termination 1 of push rod 5 directly in one end of push rod 5 processing, also can be fixedly connected with push rod 5 for individual components.
Fig. 5 and Fig. 6 shows the two states during work of this device, in Fig. 5, the piston rod 10 of cylinder 11 is in the state of inwardly shrinking, now the lower end of lever 4 rotates to the direction near push rod gripper shoe 6, the upper end of lever 4 rotates to the direction away from push rod gripper shoe 6, because mandrel 3 is positioned at strip through-hole 2, so lever 4 drives push rod 5 to move to the direction away from push rod gripper shoe 6 together, mandrel 3 moves up and down in strip through-hole 2 simultaneously, and automatic adjusting position adapts to the highly constant demand of push rod 5.This situation does not promote push rod 5, so can not realize the function to product orientation, but first push rod 5 can be retracted a segment distance when product is larger, for next step is prepared by push rod 5 pairs of product orientation.Here also found out that the push rod 5 of this device compares traditional push rod displacement scope larger, applied more convenient.
In Fig. 6, the piston rod 10 of cylinder 11 is in the state of outwards stretching out, now the lower end of lever 4 rotates to the direction away from push rod gripper shoe 6, the upper end of lever 4 rotates to the direction near push rod gripper shoe 6, lever 4 drives push rod 5 to move to the direction near push rod gripper shoe 6 together, mandrel 3 moves up and down in strip through-hole 2 simultaneously, and automatic adjusting position adapts to the highly constant demand of push rod 5.In this case, push rod 5 moves to the line of production, realizes the function to product orientation.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
