Product orientation is very common in commercial Application, when such as a certain product and other parts being carried out pressing, it is accomplished by product orientation, a kind of use pushrod advances is needed to reach location purpose detent mechanism to withstand product in some cases, if this detent mechanism adopts manual operation, push rod can swing and cause location inaccurate, affects the quality of pressing product, and manual operation labor intensity is big.
The application for a patent for invention that application number is " 201410182403.2 " discloses a kind of detent mechanism, the fixing plate of its lift cylinder is arranged on the bottom of base plate, cam lift cylinder is arranged on the fixing plate of lift cylinder, and the elevating lever of cam lift cylinder links together through base plate and cam; Being installed with cam baffle plate on base plate, cam baffle plate is provided with slide rail, and cam is provided with slide plate, slide rail and slide plate and is 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, from linear bearing traverse, base plate is also installed with the block that anti-throw-out lever swings; Cam lift cylinder action, rises cam along the slide rail on cam baffle plate, cam and roller contact, roller rolls and makes push rod move 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 big; 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 promoting push rod to move, so thrust can reduce, push rod formation can be shortened, the final promotion effect realized can be had a greatly reduced quality.
Summary of the invention
The purpose of the present invention is that provides to solve the problems referred to above that a kind of power slippages is little, compact conformation by the fixing device of the definite proportion lever drive formula pressing of lever transmission.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The fixing device of a kind of definite proportion lever drive formula pressing, including 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, the fixing device of described definite proportion lever drive formula pressing also includes lever, the stage casing of described lever is installed in lever mounting bracket by pivot shaft, described lever mounting bracket is installed on described base plate, described base plate is additionally provided with cylinder mounting seat, one end of described cylinder is articulated with in described cylinder mounting seat, the piston rod of the described cylinder other end is hinged with the lower end of described lever, the epimere of described lever is provided with axial notch, the A/F of described axial notch is less than the width in described axial notch, the termination of described push rod is provided with roller wheel shaft orthogonal with described push rod, the two ends of described roller wheel shaft are separately installed with roller, two described rollers and roller wheel shaft are placed in the axial notch of described lever, described roller can in described axial notch axial rolling.
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 be moved to the purpose of the fixing product of pressing; The axial notch of lever provides scroll space for roller, the axial notch matching mechanism of roller and lever is the height change brought to overcome lever to rotate, because push rod must move linearly at sustained height, it is capable of in lever rotary course to promote push rod to move linearly at sustained height so being coordinated by the axial notch of roller and lever.
In order to reduce the volume that takies of this device as far as possible, described cylinder mounting seat is between described push rod gripper shoe and described lever mounting bracket and near described push rod gripper shoe.
The beneficial effects of the present invention is:
The present invention is with cylinder for power part, push rod is promoted to move by lever drive, owing to the power loss of lever drive is little, and can by selecting the position of pivot shaft to determine lever two ends power input and output ratio when design, corresponding change lever two ends displacement input and output ratio, thus realizing the best collocation demand of push rod thrust and displacement; Further, since the driving equipment of lever and be can be installed within the same side of lever by dynamic equipment, so whole device takes up room little, it is simple to install.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Such as Fig. 1, shown in Fig. 2 and Fig. 3, the fixing device of definite proportion lever drive formula pressing of the present invention includes push rod 5, base plate 13, cylinder 11, push rod gripper shoe 6 and lever 1, 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 1 is installed in lever mounting bracket 9 by pivot shaft 8, lever mounting bracket 9 is installed on base plate 13, on base plate 13, between push rod gripper shoe 6 and lever mounting bracket 9, also the position of close push rod gripper shoe 6 is additionally provided with cylinder mounting seat 12, one end of cylinder 11 is articulated with in cylinder mounting seat 12, the piston rod 10 of the other end of cylinder 11 is hinged with the lower end of lever 1, the epimere of lever 1 is provided with axial notch 2, the width of the opening 14 of axial notch 2 is less than the width in axial notch 2, the termination of push rod 5 is provided with roller wheel shaft 4 orthogonal with push rod 5, the two ends of roller wheel shaft 4 are separately installed with roller 3, two rollers 3 and roller wheel shaft 4 are placed in the axial notch 2 of lever 1, roller 3 can in axial notch 2 axial rolling.
Fig. 4 and Fig. 5 illustrates two states when this device works, in Fig. 4, the piston rod 10 of cylinder 11 is in the state to contract, now the lower end of lever 1 rotates to the direction near push rod gripper shoe 6, the upper end of lever 1 rotates to the direction away from push rod gripper shoe 6, owing to two rollers 3 are blocked by the opening 14 of axial notch 2, so lever 1 drives roller 3 to move to the direction away from push rod gripper shoe 6 together with push rod 5, roller 3 moves axially in axial notch 2 simultaneously, and automatic adjusting position adapts to the height requirement that push rod 5 is constant.Push rod 5 is not promoted by this situation, so the function of the fixing product of pressing can not be realized, but first push rod 5 can be retracted a segment distance when product is bigger, prepares with the fixing product of push rod 5 pressing for next step. Here also found out that the push rod 5 of this device compares tradition push rod displacement scope more greatly, applied more convenient.
In Fig. 5, the piston rod 10 of cylinder 11 is in the state outwards stretched out, now the lower end of lever 1 rotates to the direction away from push rod gripper shoe 6, the upper end of lever 1 rotates to the direction near push rod gripper shoe 6, owing to two rollers 3 are blocked by the opening 14 of axial notch 2, so lever 1 drives roller 3 to move to the direction near push rod gripper shoe 6 together with push rod 5, roller 3 moves axially in axial notch 2 simultaneously, and automatic adjusting position adapts to the height requirement that push rod 5 is constant. In this case, push rod 5 moves to the line of production, it is achieved the function of the fixing product of pressing.
Above-described embodiment is presently preferred embodiments of the present invention; it it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, be regarded as falling within the scope of the rights protection of patent of the present invention.
