Description
Technical field
The utility model belongs to fixture, is specifically related to a kind of relay hold down gag.
Background technology
Relay is to use electronic component comparatively widely, in the process of assembling, the upper cover of relay need to be pressed in base and realize and being connected, and because relay needs good sealing property, therefore upper cover being pressed into base needs larger pressure; If employing manual operation, not only efficiency is not high, and easily because inequality firmly causes the problem such as poorly sealed between upper cover and base.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use; The relay hold down gag of even and constant pressure can be provided.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of relay hold down gag, comprises base, on described base, is fixedly connected with column; Lever is flexibly connected with described column by hinge, and briquetting is flexibly connected with the left end of described lever by hinge, and the right-hand member of described lever is connected with guide wheel; The below of described guide wheel is provided with wedge, and described wedge is fixedly connected with the push rod of cylinder; The below of described wedge is provided with backing plate, and described backing plate is fixedly connected on base; Described cylinder is fixedly connected with the cushion block of below, and described cushion block is fixedly connected on base.
Wherein, between described base and lever, be provided with back-moving spring.
Wherein, the left side of described column is provided with locating piece.
Wherein, the left end of described backing plate is provided with limit switch.
Wherein, on described base, be provided with 4 holddown grooves.
(3) beneficial effect
Compared with prior art, the location that the locating piece that the utility model adopts can be realized relay fast, the guide wheel of lever right-hand member setting can reduce the frictional force between wedge, improves the transmission efficiency of power; Briquetting adopts hinge to be flexibly connected with lever, can make in the process of pressing, and briquetting is fitted all the time and pressed surface, thereby makes relay stressed evenly, and the conforming product rate obtaining is high.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of relay hold down gag of the utility model.
Fig. 2 is the state diagram after a kind of relay hold down gag of the utility model compresses.
Fig. 3 is the vertical view of a kind of relay hold down gag of the utility model base.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of a kind of relay hold down gag of the utility model as Figure 1-3, comprises base 1, on described base 1, is fixedly connected with column 3; Lever 4 is flexibly connected with described column 3 by hinge, and briquetting 5 is flexibly connected with the left end of described lever 4 by hinge, and the right-hand member of described lever 4 is connected with guide wheel 6; The below of described guide wheel 6 is provided with wedge 9, and described wedge 9 is fixedly connected with the push rod 10 of cylinder 11; The below of described wedge 9 is provided with backing plate 8, and described backing plate 8 is fixedly connected on base 1; Described cylinder 11 is fixedly connected with the cushion block 12 of below, and described cushion block 12 is fixedly connected on base 1.
As optimization, between described base 1 and lever 4, be provided with back-moving spring.
As optimization, the left side of described column 3 is provided with locating piece 2, and described locating piece 2 is replaceable design, uses the locating piece of different sizes for the relay of different size, can ensure each location quick and precisely.
As optimization, the left end of described backing plate 8 is provided with limit switch 13, for limiting the maximum displacement of wedge 9, thereby controls the distance that briquetting 5 is pressed downwards, ensures that each relay has identical fastening force, improves the qualification rate of product.
As optimization, on described base 1, be provided with 4 holddown grooves 101, for whole relay hold down gag is fixed on to workbench.
When use, the relay that needs are clamped leans against on locating piece 2 and realizes location, promotes push rod 10 left with exhaust hood 11, because push rod 10 is fixedly connected with wedge 9, therefore wedge is moved to the left, and guide wheel 6 moves upward along the inclined-plane of wedge 9, thereby drives lever 4 to rotate counterclockwise; The left end of lever 4 drives briquetting 5 compression relay downwards simultaneously, and because briquetting 5 and lever 4 adopt chain connection, therefore, in the process compressing, briquetting 5 is fitted all the time by the surface of potential relay, realizes in the process compressing and exerting oneself evenly; Be moved to the left along with cylinder 11 promotes wedge, in the time that the left end of wedge 9 contacts limit switch 13, cylinder 11 starts to move right, thereby drives wedge 9 to move right; Lever 4 clockwise rotates under the effect of back-moving spring 7, and briquetting 5 departs from by the surface of potential relay, so far realizes and once compresses operation.
Compared with prior art, the utlity model has the features such as simple in structure, easy to operate; In the process clamping, can remain the even application of force, make relay in the process compressing stressed evenly, ensured good and qualification rate.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
