Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an assembly fixture for nuts in this embodiment includes two supporting underframe 1 installed on an assembly table, a fixing plate 2 is connected to the top of the supporting underframe 1, a plurality of guide components are installed on the fixing plate 2, a moving plate 10 is fixed between the top ends of the plurality of guide components, a push plate 14 penetrating through the fixing plate 2 is fixed to the bottom of the moving plate 10, the push plate 14 is in a U shape, the push plate 14 extends to the inner side of the supporting underframe 1, a plurality of top cylinders 7 are fixed to the top of the moving plate 10, a notch 11 is formed in the outer side of the top cylinder 7, a spring plate 12 is installed in the notch 11, a clamping block 13 extending to the inner side of the top cylinder 7 is fixed to one side of the spring plate 12 close to the top cylinder 7, a plurality of ejector rods 6 are fixed to the top of the fixing plate 2, and the top ends of the ejector rods 6 extend to the inner side of the top cylinder 7.

In the above-mentioned structure, can carry out spacingly to the nut through fixture block and springboard, can place simultaneously a plurality of nuts in the big top section of thick bamboo, then pull down through the push pedal, the cooperation guide assembly can make the movable plate steadily move down, consequently can make the ejector pin jack-in the injection mold with the nut to realize that a plurality of nuts accomplish the assembly simultaneously, and realized easy operation, reduced manufacturing cost and improved the efficiency of small batch assembly.

The guide assembly comprises four sleeves 3 arranged on a fixed plate 2, guide rods 4 are sleeved in the sleeves 3, the guide rods 4 are in a convex cylindrical shape, springs 5 are sleeved on the outer sides of the guide rods 4, the heights of the springs 5 in a natural state are larger than those of the guide rods 4, and the top ends of the guide rods 4 are fixedly connected with a movable plate 10. When the push plate drives the movable plate to move downwards, the guide rod can be used for enabling the movable plate to move downwards stably, and meanwhile, the spring can be extruded between the movable plate and the fixed plate, so that when the push plate loses pressure, the elastic force of the spring can drive the movable plate to reset, and the next assembly is convenient.

In addition, the width of the spring plate 12 is smaller than the width of the inside of the notch 11, and the clamping block 13 is hemispherical. When the nut is pressed into the top cylinder, the clamping block can squeeze the spring plate, and the spring plate is smaller than the width of the notch, so that the spring plate can move inside the notch, and the spring plate is prevented from moving out to influence the diameter of the top cylinder.

For correction, a plurality of positioning posts 9 are fixed on the top of the moving plate 10. When injection mold's location pinhole is connected with the reference column to can play the effect of correction, avoid because injection mold does not align and be difficult to the assembly.

In order to assemble nuts of different types, a plug 8 is fixed at the top end of part of the ejector rod 6, the plurality of ejector cylinders 7 are divided into a large diameter and a small diameter, the diameter of the ejector rod 6 is equal to the inner diameter of the small diameter of the ejector cylinder 7, and the plug 8 is positioned in the large diameter of the ejector cylinder 7. Therefore, nuts of different types can be supported through the ejector head and the ejector rod, and accordingly the nuts of different types can be synchronously finished in the injection mold of the nut assembly belt.

The working principle of the embodiment is as follows:

Through pressing in the nut into inside the roof cylinder, the nut can extrude the fixture block, can extrude the elastic plate simultaneously, then under the effect of the toughness of elastic plate, can drive the fixture block and fix a position the nut, therefore can realize spacing to the nut, ejector pin and top can support the nut of different models simultaneously, then insert injection mold's location pinhole's inside when the reference column, thereby can realize correcting roof cylinder and injection mold alignment, then push down the push pedal, the push pedal can drive the movable plate and move down, the movable plate is located the sleeve through driving the guide post and slides, consequently, the guide post can play the movable plate and stably remove, the movable plate moves down the in-process of moving down, roof cylinder moves down thereupon, consequently ejector pin and roof cylinder can upwards promote the nut, accomplish the assembly until the propelling movement is to injection mold, simultaneously the movable plate can extrude the spring, when releasing the pressure to the push pedal, the elasticity of spring can drive the movable plate and get back to the normal position, consequently can be convenient for the next equipment to join in marriage filling of nut.

In conclusion, the nuts of different models can be assembled simultaneously, the efficiency of small-batch assembly is improved, the production cost can be reduced, and meanwhile, the operation is convenient.

The entire workflow is completed and what is not described in detail in this specification is well known to those skilled in the art.
