Since the overall weight of the clamping device for LED lighting production is relatively large, it is not convenient to replace the clamping device for LED lighting production. In order to solve this technical problem, the utility model proposes a clamping device for LED lighting production. Utility Model Content

[0004] The main purpose of the utility model is to provide a clamping device for LED lighting production, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a clamping device for LED lighting production includes a connecting plate 1 and two clamps 2. The upper surface of the connecting plate 1 is connected to a support seat 3, and the support seat 3 and the connecting plate 1 are fixedly connected. The slide seat 4 is slidably connected to the connecting plate 1, and the distance between the slide seat 4 and the support seat 3 is changed by sliding. At the same time, the lampshade is clamped and fixed and the fixing restriction is released by sliding the slide seat 4. The upper surface of the connecting plate 1 is slidably connected to the slide seat 4, and a hydraulic cylinder 5 is arranged on the outside of the slide seat 4. The hydraulic cylinder 5 provides power for moving the slide seat 4. The upper surface of the connecting plate 1 is connected to a support frame 14, and one side of the support frame 14 is connected to the hydraulic cylinder 5. The output end of the hydraulic cylinder 5 is connected to one side of the slide seat 4. The support frame 14 is located behind the slide seat 4, and the support frame 14 provides support force for the hydraulic cylinder 5.

[0024] The inside of the support seat 3 and the slide seat 4 are both detachably connected with a clamping block 6, and one side of the two clamping blocks 6 located outside the slide seat 4 and the support seat 3 is connected to one side of the two clamps 2. When the slide seat 4 moves, the clamp 2 is driven to move to the position of the other clamp 2, so that the two clamps 2 are in contact, thereby clamping and fixing the lampshade.

[0025] A card slot 7 is provided on the inner side of the card block 6, and the inner walls of the support seat 3 and the slide seat 4 are slidably connected with a positioning plug 8, one end of the positioning plug 8 is in contact with the inner wall of the card slot 7, and the positioning plug 8 is inserted into the card slot 7 to limit the movement of the card block 6. At the same time, the card block 6 limits the movement of the chuck 2, and the positioning plug 8 is in contact with the card slot 7 to fix the card block 6. After the positioning plug 8 is out of contact with the card slot 7, the positioning restriction on the card block 6 is released.

[0026] The inner sides of the support seat 3 and the slide seat 4 are both threadedly connected with a screw rod 9, and the rotation of the screw rod 9 provides power for moving the positioning plug 8, thereby driving the positioning plug 8 to move. The other end of the screw rod 9 is connected to a fixed block 10, and the inner wall of the fixed block 10 is slidably connected to a force rod 11. The force rod 11 facilitates the rotation of the screw rod 9 and reduces the physical force output when rotating the screw rod 9. The other end of the screw rod 9 is connected to the other end of the positioning plug 8 for fixed-point rotation. The slot 7 has an inclination angle, and the positioning plug 8 has the same inclination angle as the slot 7. The inclination angle facilitates the positioning plug 8 to push the block 6 to move through the slot 7.

[0027] A slide groove 12 is provided on the inner side of the slide seat 4, and a guide rail 13 is connected to the upper surface of the connecting plate 1. The outer surface of the guide rail 13 is slidably connected to the inner wall of the slide groove 12. The slide seat 4 is in sliding contact with the guide rail 13 through the slide groove 12. The guide rail 13 can improve the stability of the slide seat 4 when sliding. When the chuck 2 clamps the lampshade, the slide seat 4 will be subjected to the reaction force of the lampshade. The slide seat 4 has no stable support, which will cause insufficient stability in clamping the lampshade and lead to too low processing accuracy.

[0028] A positioning groove 15 is provided on the inner side of one of the chucks 2, and a positioning pin 16 is connected to one side of the other chuck 2. The positioning groove 15 is adapted to the positioning pin 16. After the two chucks 2 are brought close together, the positioning pin 16 is inserted into the positioning groove 15, so that the two chucks 2 form a whole and restrict each other, thereby improving the overall stability of the two chucks 2 and further improving the processing accuracy of the lampshade.

[0029] The inner walls of the two chucks 2 are connected with a tray 17, and the tray 17 is semicircular in shape. After the two chucks 2 are combined together, the two trays 17 form a ring, and the tray 17 is located at the bottom of the chuck 2. The tray 17 plays a supporting role at the bottom of the chuck 2, and has a supporting and positioning effect on the lampshade. At the same time, it can quickly position the lampshade, and there is no need to repeatedly measure when tightening and fixing the lampshade to determine the tightening position of the lampshade.

[0030] It should be noted that when the chuck 2 needs to be replaced during actual use of the device, the hydraulic cylinder 5 is first started to pull the slide 4 away from the support seat 3 to create a distance between the chucks 2 and the chucks 2, and then the screw rod 9 is rotated by the force rod 11. The screw rod 9 drives the positioning plug 8 to move its position during rotation, and then the positioning plug 8 is disengaged from the contact with the slot 7. The chuck 2 is picked up and pulled out of the support seat 3 and the slide 4, and then the chuck 2 to be used is placed in the support seat 3 and the slide 4. The screw rod 9 is rotated to push the positioning chuck 2 to move to the position of the slot 7, and then the positioning plug 8 is tightly in contact with the slot 7 to limit the movement of the chuck 2.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
