Technical Field

The utility model belongs to the technical field of optical device processing equipment, and particularly relates to a pressing structure for an elastic clamp.

Background

The elastic clamp is a tool for clamping products by utilizing the elasticity of the elastic piece. The elastic clamp is generally provided with a fixed part, a movable part and an elastic piece, wherein the elastic piece is positioned between the fixed part and the movable part, when the movable part is connected with the fixed part through a fastener, the movable part and the fixed part can squeeze the elastic piece and deform the elastic piece, and when the elastic piece deforms, pressure is formed on a product to be clamped, so that the effect of fixing the product is achieved.

The elastic piece is always in an energy storage state when clamping the product, and the elastic piece can rebound to the original position when the connection between the fixed part and the movable part is loosened. When the fastening piece between the movable part and the fixed part of the elastic clamp is removed, the elastic piece can slowly stretch and recover to the original shape under the limiting action of the movable part and the fixed part. However, when the fastener between the movable part and the fixed part is completely taken out, the elastic part cannot be limited due to no connecting force between the movable part and the fixed part, and the elastic part can rebound rapidly at the moment, so that the movable part and the elastic part bounce or the product bounces off, and accidents on production are caused.

Therefore, when the elastic clamp is loosened, the elastic piece of the elastic clamp rebounds rapidly, so that the product or the clamp bounces.

Detailed Description

The technical scheme of the utility model is clearly and completely described by a specific implementation mode of the embodiment of the utility model with the aid of the attached drawings.

Referring to fig. 1 and 3, the present utility model is a pressing structure for an elastic clamp 5, which includes a pressing arm 1, a steering cylinder 2 and an electric displacement table 4. Wherein the displacement direction of the electric displacement table 4 is a vertical direction for controlling the ascending and descending of the pressing arm 1. The lifting part of the electric displacement table 4 is fixed with a turning block, the steering cylinder 2 is fixed on the turning block, and one end of the pressing arm 1 is connected with the turning part of the steering cylinder 2. The turning part of the steering cylinder 2 turns in the horizontal plane, and the press arm 1 follows the turning when the turning part of the steering cylinder 2 turns.

In another embodiment, the electric displacement table 4 may be replaced by a screw-nut pair, the pressing arm 1 is fixed on the nut pair, and the screw can be rotated to control the lifting and lowering of the nut pair.

As shown in fig. 2, the pressing arm 1 is located above the elastic clamp 5, and when the elastic clamp 5 needs to be pressed, the elastic clamp 5 clamps the product. When the electric displacement table 4 moves downwards, the pressing arm 1 presses down on the movable part of the elastic clamp 5, so that the movable part of the elastic clamp 5 is pressed. After the elastic clamp 5 is pressed, the elastic clamp 5 can be fixed by a fastener such as a screw. When the product clamped on the elastic clamp 5 needs to be taken out, the fasteners such as the screws are removed, then the elastic clamp 5 is loosened, the electric displacement table 4 moves upwards, the pressure of the pressing arm 1 on the elastic clamp 5 is gradually reduced, and finally the pressing arm 1 is separated from the elastic clamp 5, so that the pressure on the elastic clamp 5 is not formed. When the fastener on the elastic clamp 5 is removed, the pressing arm 1 always presses on the elastic clamp 5, so that the elastic clamp 5 cannot bounce under the action of elastic force, and the product cannot fall off and be damaged due to elastic force release. The upward moving process of the pressing arm 1 is a process of slowly releasing the elastic force of the elastic clamp 5, so that the accumulated elastic force of the elastic clamp 5 is slowly released in the upward moving process of the pressing arm 1, and the problem that the elastic force is quickly released to cause the bouncing of the movable part when the elastic clamp 5 is released for clamping is solved. The elastic clamp 5 and the electric displacement table 4 are respectively fixed on the two layers of platforms, the elastic clamp 5 is positioned on the upper layer of platform, the electric displacement table 4 is fixed on the lower layer of platform,

after the pressing arm 1 is lifted and separated from the elastic clamp 5, the steering cylinder 2 starts to work, and the pressing arm 1 is moved away from the upper side of the elastic clamp 5, so that workers or other equipment can grasp or place the elastic clamp 5 and the product from the upper side. The arrangement of the rotating cylinder can prevent the pressing arm 1 from blocking the upper side of the elastic clamp 5. The rotating cylinder is positioned at one side of the elastic clamp 5, so that the rotating angle of the pressing arm 1 is controlled to be about 90 degrees. Thus, the steering cylinder 2 can directly purchase the 90 ° steering cylinder 2.

As shown in fig. 3, the connecting block 3 has a vertically symmetrical structure, an upper connecting plate for fixing the steering cylinder 2 is provided at the upper side, and a lower connecting plate for connecting the electric displacement table 4 is provided at the lower side. The upper connecting plate and the steering cylinder 2 can be fixedly connected through bolts or screws, and the lower connecting plate and the electric displacement table 4 can be fixedly connected through bolts or screws. The cross-sectional dimension of connecting block 3 middle part is less than the size of upper connecting plate and lower connecting plate. That is, the space for installing the screw is formed on the lower side of the upper connecting plate and the upper side of the upper connecting plate, so that the upper connecting plate is conveniently connected with the steering cylinder 2 by adopting the screw, and the lower connecting plate is also conveniently connected with the electric displacement table 4.

As shown in fig. 4, the pressing arm 1 includes an arm frame 102 and a force-optimizing glue pressing block, where the force-optimizing glue pressing block is in a strip shape, and the force-optimizing glue pressing block is fixed on the arm frame 102. The bottom of the you li jiao press block passes through the arm support 102 and extends to the lower side of the arm support 102. Therefore, when the pressing arm 1 presses down the elastic clamp 5, the optimal force rubber press block contacts with the elastic clamp 5. When the pressure arm 1 needs to press down and position the plurality of parallel elastic clamps 5, even if the dimensional accuracy of the plurality of parallel elastic clamps 5 has deviation, the pressure block of the high-strength adhesive can only generate different deformations. Therefore, by arranging the high-strength adhesive pressing block, the high-strength adhesive pressing block can be used for pressing and positioning the plurality of elastic clamps 5 which are arranged in parallel, so that the stability of the pressing effect of the pressure arm 1 on the plurality of elastic clamps 5 is ensured.

As shown in fig. 5, a protruding structure 105 is disposed at the bottom of the you li adhesive block, the protruding structure 105 passes through the middle of the arm support 102, and the bottom of the protruding structure 105 passes through the arm support 102 and protrudes from the bottom of the arm support 102. When the pressing arm 1 presses down the elastic jig 5, the protruding structure 105 is brought into contact with the elastic jig 5. That is, the pressing arm 1 presses down the elastic clamp 5, and the convex structure 105 is a contact point and a force receiving point. The bump structure 105 is a part of the optimal force glue block, so that the bump structure 105 is stressed and deformed, and when each elastic clamp 5 is pressed in place, even if the height sizes of the elastic clamps 5 are different, the deformation of the bump structure 105 can be compensated. Even if there are differences in the height dimensions of the elastic jigs 5, the projection structures 105 located at the bottom of the pressing arm 1 can press all the elastic jigs 5 by deforming under sufficient pressure provided by the electric displacement table 4.

In another embodiment, the you li glue block can also be replaced by a rubber block.

As shown in fig. 6, a boss 101 is provided at an end of the arm support 102, a fixing hole 104 is provided at the boss 101, and the arm support 102 passes through the fixing hole 104 with a screw and is connected with a rotating portion of the steering cylinder 2. Under the condition that the high-strength adhesive pressing block is fixed on the upper side of the arm support 102, the top height of the high-strength adhesive pressing block is the same as the height of the boss 101. The boss 101 is arranged to increase the axial length of the fixing hole 104, the connection area with the rotating cylinder is increased, the stability of connection of the arm support 102 and the rotating cylinder is increased, and the top of the high-strength adhesive pressing block is level with the boss 101, so that the shape of the pressing arm 1 is more attractive.

As shown in fig. 7, the arm support 102 is provided with a strip hole 106, and the length direction of the strip hole 106 is set along the length direction of the arm support 102. Screw holes for fixing the high-strength adhesive pressing blocks are formed in two ends of the strip holes 106, and two ends of the high-strength adhesive pressing blocks can be fixed on the arm support 102 through screws. When the part of the you li jiao press block passing through the strip hole 106 is stressed, the middle part of the you li jiao press block can be bent and deformed upwards, and the strip hole 106 is arranged to increase the deformability degree of the you li jiao press block. The strip hole 106 is matched with the high-strength adhesive pressing block, so that the thickness of the whole pressing arm 1 can be reduced, if the high-strength adhesive pressing block with the same thickness is directly overlapped and fixed with the arm support 102, the deformation degree of the high-strength adhesive pressing block can be reduced because of the supporting effect of the arm support 102 on the high-strength adhesive pressing block, the thickness of the whole pressing arm 1 is increased, and the required space of the whole equipment is also increased.
