Description

Technical Field

[0001] The invention belongs to the technical field of clamping tooling, and in particular relates to a clamping tooling for producing and processing lighting fixtures and a clamping and fixing method thereof. Background Art

[0002] Lighting fixtures refer to various equipment and devices used for lighting. They have different structures and uses to meet the lighting requirements of different places and needs, including light sources, lampshades and bases. The clamping tooling used for the production and processing of lighting fixtures is a tool designed specifically for the production and processing of lighting fixtures. It is used to clamp and position the workpiece quickly and accurately for subsequent processing operations. The most common lampshade at present is a frustum-shaped lampshade, which requires stable clamping and fixation for processing operations.

[0003] The clamping tooling used for the production and processing of lighting fixtures in the prior art is usually used to clamp and fix the lampshade during use, and then perform subsequent processing. For the most common truncated cone-shaped lampshade, the existing clamping and fixing is difficult due to the complex arc surface of the outer side surface. The actual contact area of ​​the clamping part on the outer arc surface of the lampshade is limited, and the force is small. Usually, the clamping force is strengthened to maintain the stability of the clamping and fixing. However, when the clamping force is too large, it is easy to cause pressure damage to the clamped lampshade. Even when a splint adapted to the outer side of the truncated cone-shaped lampshade is used, a large clamping force is still required to maintain stability. When the pressure is reduced, it is easy to loosen and shift. It is difficult to balance stability and safety when clamping and fixing the truncated cone-shaped lampshade, and the actual use effect is not good.

[0004] In addition, during use, the clamping tooling used for the production and processing of lighting fixtures in the prior art, especially for the production and processing of frustum-conical lampshades with different sizes and specifications, in order to ensure stable clamping, when the clamping plate provided has an adaptive arc surface, it is restricted by the arc surface and can only fully fit and clamp lampshades of a single size and specification. When lampshades of different sizes and specifications need to be processed, the clamping plate needs to be replaced. The actual replacement operation is troublesome and the use effect is not good.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1.

While completing sufficient clamping and fixing, it cooperates with the start of the vacuum pump and the pushing component to suck the air in the internal chamber of the elastic metal clamping plate. When the suction holes in the elastic metal clamping plate are tightly fitted with the outer side surface of the lampshade, a negative pressure state is achieved inside the elastic metal clamping plate, so that the lampshade is tightly adsorbed on the elastic metal clamping plates on both sides.

[0041] Embodiment 1: The truncated cone-shaped lampshade is located between the supporting parts 5, the air supply component 10 is started, the air pump 101 inputs pressurized air into the curved pipe 102, and the pressurized air is passed into the rotating connecting component 3 through the connecting cover 103, the control valve 33 is kept started, and the pressurized air input into the connecting shaft 32 is input into the pushing components 6 on both sides, the internal air pressure of the pushing component 6 increases, and the push rod 62 is pushed to move, the spring 64 is stretched, the push rod 62 moves horizontally and pushes, driving the elastic metal clamps 7 on both sides to move and approach the truncated cone-shaped lampshade to be clamped, the matching surface of the front of the elastic metal clamp 7 is attached to the outer side of the truncated cone-shaped lampshade, the preliminary clamping is completed, and the vacuum pump 11 is started, and the vacuum pump 11 sucks the push rod 6 in the pushing component 6 2, and guide the suction of the internal gas of the elastic metal clamp 7, so that the elastic metal clamp 7 is adsorbed and fixed to the outer side of the truncated cone-shaped lampshade under negative pressure, completing the enhanced fixation after clamping. When processing at different angles is required, the power mechanism 4 is started to drive the meshing gear 9 to rotate, and drive the rotating connecting component 3 to rotate, so that the clamped lampshade deflects in the direction; when cleaning is required, the control valve 33 is started to switch the ventilation direction, so that the airflow is input into the connecting plate 31 and passes into the bypass groove 34, and then input into the interior of the support part 5, and the pressurized air is fed to fill the interior of the support arm 51, and the fixedly clamped lampshade is purged along the inclined air outlet 53, and the cleaning operation is completed before, during and after processing.
