Description

Technical Field

[0001] This utility model relates to the field of assembly line technology, and in particular to a multi-station assembly fixture for a lamp charger. Background Technology

[0002] After the PCB board of the mining lamp charger is surface-mounted, it needs to be assembled. The PCB board is installed in the housing of the mining lamp charger and fixed in place. To facilitate assembly, tooling is used to position and fix the components. To increase assembly efficiency, an assembly line is used, with each worker responsible for one assembly step. However, when the existing tooling moves on the guide rail, friction occurs between the rollers at the lower end of the tooling and the guide rail. Over time, this causes the rollers to wear, resulting in the tooling shaking during movement. This can cause misalignment of the components assembled within the tooling, affecting subsequent assembly. Summary of the Invention

[0003] The purpose of this utility model is to provide a multi-station assembly fixture for a lamp charger. By rotating and squeezing the bolts, the diameter of the rubber ring can be changed, thereby changing the clamping force between the guide rail and the roller, ensuring that the roller can move smoothly along the guide rail, thus solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a multi-station assembly fixture for a lamp charger, including a ring-shaped worktable, a guide rail and a conveyor belt fixedly connected to the ring-shaped worktable, a fixed support slidably connected to the guide rail, the guide rail and the conveyor belt cooperating to drive the fixed support to move around the ring-shaped worktable, and an assembly fixture for assembling lamp chargers fixedly connected to the upper end of the fixed support. A connecting plate is fixedly connected to the side of the fixed support facing the conveyor belt. Two snap-fit ​​plates are fixedly connected to the side of the connecting plate facing the conveyor belt. The conveyor belt pulls the snap-fit ​​plates and the fixed support to move, thereby changing the position of the fixed support and realizing assembly line assembly. A traction block is fixedly connected to the side of the conveyor belt. The lower end of the fixed support is provided with four rollers, which clamp each other with the guide rail to limit and support the fixed support. The side of the roller is provided with a circular slot, and the inside of the slot is provided with two arc-shaped plates. Rubber rings are fitted on the outer walls of the two arc-shaped plates to change the tightness of the clamping between the roller and the guide rail. The lower end of the roller is threaded with a compression bolt. When the stroke of the compression bolt changes, the compression force of the arc plate on the rubber ring changes.

[0005] Preferably, both the inner and outer walls of the guide rail are provided with protrusions, and the roller engages with the protrusions of the guide rail through a slot, which is used to limit the roller installation onto the guide rail.

[0006] Preferably, a connecting column is rotatably connected to the upper middle of the roller, the side wall of the connecting column has a stepped structure, the fixed support has a through mounting hole in the middle, the inner side wall of the mounting hole has a stepped structure, the connecting column is inserted into the mounting hole, and the fixed support and the connecting column are connected into a whole by bolts.

[0007] Preferably, the rollers are arranged in pairs, and a pair of rollers are clamped on each side of the guide rail to drive the fixed support to move smoothly.

[0008] Preferably, a top plate is slidably connected to the middle of the roller, and arc-shaped plates are fixedly connected to both ends of the top plate. The roller passes through both ends of the top plate, and the top end of the pressing bolt abuts against the lower end of the top plate. The pressing force on the top plate changes when the pressing bolt rotates.

[0009] Preferably, the arc plate has a semi-circular structure, and two arc plates form a circular structure. The outer wall of the arc plate is inclined, and the inner wall of the rubber ring is inclined. When the arc plate moves up and down, the diameter of the rubber ring changes.

[0010] Preferably, the traction block has a T-shaped structure, and a T-shaped connecting groove is formed between the two snap-fit ​​plates. The traction block is inserted into the connecting groove between the two snap-fit ​​plates. When the conveyor belt drives the traction block to move, the traction block pulls the fixed support to move.

[0011] The beneficial effects of this utility model are as follows: by cooperating with the guide rail and the conveyor belt, the fixed support moves around the circular worktable, changing the position of the fixed support, so that the assembly process of the lamp charger can be carried out continuously, realizing assembly line production and improving assembly efficiency; when the roller wears due to long-term use, causing the roller to shake when it moves along the guide rail, the rotating compression bolt lifts the top plate and the arc plate, thereby increasing the diameter of the rubber ring and increasing the clamping force between the roller and the guide rail, making the roller move more smoothly along the guide rail, ensuring that the fixed support does not shake when it moves along the guide rail, and avoiding affecting the assembled parts.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] See Figures 1-4 This utility model provides a multi-station assembly fixture for a lamp charger, including a circular worktable 1. A guide rail 4 and a conveyor belt 8 are fixedly connected to the circular worktable 1. The fixed connection method can also be welding, riveting, screwing, or gluing. A fixed support 2 is slidably connected to the guide rail 4. The guide rail 4 and the conveyor belt 8 cooperate to move the fixed support 2 around the circular worktable 1. An assembly fixture 3 for assembling the lamp charger is fixedly connected to the upper end of the fixed support 2. By cooperating with the guide rail 4 and the conveyor belt 8 to move the fixed support 2 around the circular worktable, the position of the fixed support 2 is changed, allowing the lamp charger assembly process to be carried out continuously.

[0019] Both the inner and outer walls of the guide rail 4 are provided with protrusions 5. The roller 11 engages with the protrusions 5 of the guide rail 4 through the slot 12, which is used to limit the installation of the roller 11 onto the guide rail 4. When installing the roller 11 onto the guide rail 4, the roller 11 engages with the protrusions 5 through the slot 12, thereby limiting the installation of the roller 11 onto the guide rail 4. This prevents the roller 11 from dislodging from the guide rail 4 during movement. At the same time, it also limits the fixed support 2, ensuring the accuracy and stability of the fixed support 2 during movement.

[0020] A connecting post 14 is rotatably connected to the upper center of the roller 11. The side wall of the connecting post 14 has a stepped structure. The fixed support 2 has a through mounting hole 6 in the middle. The inner side wall of the mounting hole 6 has a stepped structure. The connecting post 14 is inserted into the mounting hole 6, and the fixed support 2 and the connecting post 14 are connected as a whole by bolts. This facilitates the installation and disassembly of the roller 11 and the fixed support 2, and is beneficial for equipment maintenance and parts replacement. A connecting plate 7 is fixedly connected to the side end of the fixed support 2 facing the conveyor belt 8. Two snap-fit ​​plates 10 are fixedly connected to the side end of the connecting plate 7 facing the conveyor belt 8. The conveyor belt 8 pulls the snap-fit ​​plates 10 and the fixed support 2 to move, thereby changing the position of the fixed support 2 and realizing assembly line assembly. A traction block 9 is fixedly connected to the side end of the conveyor belt 8. The lower end of the fixed support 2 is provided with four rollers 11, which are arranged in pairs. Each side of the guide rail 4 holds a pair of rollers 11. The rollers 11 and the guide rail 4 clamp each other to limit and support the fixed support 2 and drive it to move smoothly. The side of the roller 11 is provided with a circular groove 12. Inside the groove 12 are two arc-shaped plates 16. Rubber rings 17 are fitted on the outer walls of the two arc-shaped plates 16 to change the tightness of the clamping between the roller 11 and the guide rail 4. The arc-shaped plates 16 are semi-circular ring structures. The two arc-shaped plates 16 form a circular ring structure. The outer walls of the arc-shaped plates 16 are inclined, and the inner walls of the rubber rings 17 are also inclined. When the arc-shaped plates 16 move up and down, the diameter of the rubber rings 17 changes. When the arc plate 16 is lifted and moved upward, it can expand the diameter of the rubber ring 17, so that the outer wall of the rubber ring 17 abuts against the protrusion 5 of the guide rail 4, changing the tightness of the clamping between the roller 11 and the guide rail 4, limiting and supporting the fixed support 2. The tightness of the clamping between the roller 11 and the guide rail 4 can be flexibly adjusted to ensure the stability of the fixed support 2 during movement, which is conducive to improving assembly accuracy.

[0021] A clamping bolt 13 is threadedly connected to the lower end of roller 11. When the stroke of clamping bolt 13 changes, the clamping force of arc plate 16 on rubber ring 17 changes. A top plate 15 is slidably connected to the middle of roller 11. Arc plates 16 are fixedly connected to both ends of top plate 15, and both ends of top plate 15 pass through roller 11. The top end of clamping bolt 13 abuts against the lower end of top plate 15. The clamping force of clamping bolt 13 on top plate 15 changes when clamping bolt 13 rotates. When a worker uses a hex wrench to tighten clamping bolt 13, the position of clamping bolt 13 toward the top end of top plate 15 changes, thereby changing the clamping force of clamping bolt 13 on top plate 15, and thus changing the clamping force of arc plate 16 on rubber ring 17. This optimizes the adjustment structure of the clamping tightness between roller 11 and guide rail 4, making the adjustment more precise and reliable.

[0022] The traction block 9 has a T-shaped structure, with a T-shaped connecting groove formed between the two snap-fit ​​plates 10. The traction block 9 is inserted into the connecting groove between the two snap-fit ​​plates 10. When the conveyor belt 8 drives the traction block 9 to move, the traction block 9 pulls the fixed support 2 to move. After the fixed support 2 and the guide rail 4 are installed, the connecting plate 7 is snapped into the traction block 9 through the snap-fit ​​plates 10. At this time, the fixed support 2 is moved to the connecting plate 7, connecting the connecting plate 7 to the fixed support 2. When the conveyor belt 8 drives the traction block 9 to move, it can reliably pull the fixed support 2 to move, ensuring the stability and accuracy of power transmission and ensuring the normal operation of the assembly fixture.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
