Technical Field

[0001] The utility model relates to the field of hot riveting, in particular to hot riveting equipment for installing internal parts of a vehicle lamp. Background Art

[0002] In the installation of internal parts of car lights, hot riveting equipment can be used to fix parts made of plastic, metal or other materials together. The use of hot riveting equipment can provide an efficient and reliable connection method and is suitable for the installation of various internal parts of car lights, such as bulb holders, lampshade fixings, etc. Hot riveting equipment can improve production efficiency, reduce manual operations, and ensure the firmness and sealing of the connection of internal parts of car lights.

[0003] At present, when connecting various parts of a car lamp by means of a hot riveting device, the hot riveting head needs to contact the parts. However, in the process of pressing down the hot riveting head, the operator usually controls the pressing distance of the hot riveting head based on operating experience. However, if the pressing distance is too large, the hot riveting head may damage the car lamp parts, thereby causing economic losses. Therefore, in view of the above problem, a hot riveting device for installing internal parts of a car lamp is proposed. Utility Model Content

Figure 1A hot riveting device for installing internal parts of a vehicle lamp comprises a workbench 1; a hydraulic rod 2 is fixedly installed inside the workbench 1, a connecting plate 31 is fixedly connected to the output end of the hydraulic rod 2, a hot riveting head 32 is fixedly installed at the bottom end of the connecting plate 31, a supporting column 4 is fixedly installed on the surface of the workbench 1, a triggering component 5 is arranged on the surface of the hot riveting head 32, and a limiting component 6 is arranged inside the supporting column 4;

[0025] Reference Figure 2 - Figure 4 The trigger assembly 5 includes a hollow cylinder 51 fixedly mounted on the rear end of the hot riveting head 32. A spiral groove 52 is provided inside the hollow cylinder 51. A moving rod 53 is slidably connected inside the hollow cylinder 51. A return spring 54 is fixedly mounted on the surface of the moving rod 53. A fixing ring is fixedly mounted on the rear end of the bottom of the hot riveting head 32. The moving rod 53 is slidably connected to the inside of the fixing ring. The bottom end of the moving rod 53 is located below the bottom end of the hot riveting head 32. The bottom end of the return spring 54 is fixedly mounted on the top of the fixing ring. The fixing ring guides the moving direction of the moving rod 53 so that the moving rod 53 keeps moving vertically up and down. A protrusion 55 is fixedly installed on the surface, a winding rod 56 is fixedly installed on the top of the hollow cylinder 51, a pull rope 57 is wound around the surface of the winding rod 56, a rotating rod 58 is rotatably connected to the bottom end of the connecting plate 31, a torsion spring 59 is fixedly connected to the surface of the rotating rod 58, the protrusion 55 is slidably connected to the inside of the spiral groove 52, the end of the pull rope 57 away from the winding rod 56 is wound around the surface of the rotating rod 58, and the end of the torsion spring 59 away from the rotating rod 58 is fixedly connected to the bottom wall of the connecting plate 31. When the moving rod 53 moves, the protrusion 55 will be driven to move. At this time, the protrusion 55 moves inside the spiral groove 52 and then drives the hollow cylinder 51 to rotate.

[0026] Reference Figure 1 -and Figure 5The limiting component 6 includes a limiting ring 61 fixedly installed on the left and right sides of the rotating rod 58, a gear 62 is rotatably connected to the surface of the rotating rod 58, a slide groove 63 is provided on the left and right sides of the inside of the support column 4, and a vertical groove 64 is provided on the side of the support column 4 close to the middle of the workbench 1, a slider 65 is slidably connected to the inside of the slide groove 63, a push plate 66 is slidably connected to the surface of the slider 65, and a rack 67 is fixedly connected to the bottom end of the push plate 66. The limiting ring 61 has two groups and each group has two. The gear 62 is located between the two limiting rings 61, and the gear 62 and the rack 67 are meshed and connected. The two limiting rings 6 The position of the gear 62 is limited so that the gear 62 cannot slide in the horizontal direction of the rotating rod 58. A sliding plate 68 is provided at the front end of the support column 4. The rotating rod 58 passes through the vertical slot 64 and extends to the inside of the support column 4. The front end of the push plate 66 is adapted to contact with the sliding plate 68. A telescopic rod is fixedly connected between the upper and lower sides of the rear end of the sliding plate 68 and the inner wall of the support column 4. When the push plate 66 is pushed, it will push the sliding plate 68. At this time, the sliding plate 68 will stretch the telescopic rod, and then the sliding plate 68 will press the sliding plate 68, so that the sliding plate 68 abuts against the inside of the connecting plate 31.

[0027] Working principle: the operator energizes the hot riveting head 32, then places the headlight part at the bottom of the workbench 1, and then drives the hydraulic rod 2 to drive the connecting plate 31 to move downward. At this time, the connecting plate 31 drives the hot riveting head 32 to move downward and hot rivet the part; when the hot riveting head 32 moves downward until it contacts the headlight part, since the bottom end of the moving rod 53 is located below the bottom end of the hot riveting head 32, the moving rod 53 contacts the headlight part first. When the hot riveting head 32 continues to move downward, the moving rod 53 moves upward in the hollow cylinder 51 under the reaction force. At this time, the moving rod 53 drives the protrusion 55 to slide upward in the spiral groove 52. At this time, the protrusion 55 pushes the hollow cylinder 51 to rotate, and the hollow cylinder 51 rotates and winds the pull rope 57. At this time, the pull rope 57 pulls the rotating rod 58 to rotate, and the rotating rod 58 pulls the torsion spring 59 to accumulate elastic force.

[0028] When the rotating rod 58 rotates, the rotating rod 58 will drive the gear 62 to rotate through the friction force. At this time, the gear 62 will drive the meshing rack 67 to move forward. At this time, the rack 67 will drive the fixedly connected push plate 66 to move accordingly. At this time, the push plate 66 will slide forward on the surface of the slider 65, and then the push plate 66 will push the sliding plate 68 to stretch the telescopic rod and move forward, thereby causing the sliding plate 68 to move forward and abut against the inside of the connecting plate 31. At this time, the connecting plate 31 is limited by the friction force between the sliding plate 68 and the connecting plate 31 to prevent the connecting plate 31 from continuing to move downward and causing the hot rivet head 32 to damage the car lamp parts; if the rotating rod 58 continues to rotate afterwards, the inner walls of the sliding plate 68 and the connecting plate 31 contact each other and cannot continue to move forward. Therefore, the push plate 66 cannot continue to move forward. At this time, the rotating rod 58 cannot drive the gear 62 to continue to rotate. Therefore, slippage occurs between the gear 62 and the rotating rod 58, that is, at this time, the gear 62 rotates between the two limit rings 61 on the surface of the rotating rod 58.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and 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, and these changes and improvements fall within the scope of the utility model to be protected.
