[0001] The utility model relates to the field of headlamp housing processing, in particular to a headlamp housing grinding device. Background Technique

[0002] An automobile headlamp is a lighting device that can emit light when powered on. The main body consists of a power connection end, a lamp cover, and internal electrical appliances. In the production and processing of automobile lamps, to ensure their beauty, it is usually necessary to polish and grind the outer surface of the lamp cover with a polishing and grinding tool.

[0003] Generally, a grinding machine is needed for grinding the headlamp housing. Most of the existing automobile housing grinding devices are composed of a driving device and a grinding wheel. After the worker fixes the headlamp housing to be ground on the end face of the workbench, the height of the grinding device is controlled by hand to achieve the purpose of grinding the headlamp housing.

[0004] However, when grinding the existing headlamp housing, the worker needs to manually fix it on the end face of the workbench through specific fixing components such as cylinders or bolts, and then the worker holds the grinding device to grind the headlamp housing. This fixing method requires the worker to fix and release the restriction for each group of housings during processing, and repeated handling will increase the worker's labor intensity, thus affecting the overall work efficiency. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a headlamp housing grinding device to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A headlamp housing grinding device includes a work box. One end of the work box is movably installed with a grinding device, and a first rotating rod is movably installed inside the work box. A gear is fixedly installed in the middle of the first rotating rod. A first moving rod is movably installed inside the work box, and the two first moving rods are symmetrically arranged. One ends of the two first moving rods are respectively installed with a first tooth plate and a second tooth plate, and the first tooth plate and the second tooth plate are engaged with the gear. A second moving rod is movably installed inside the work box, and a guide rod is fixedly installed at one end of the second moving rod. A guide groove matching the guide rod is opened inside the first rotating rod. Auxiliary components for fixing the headlamp housing are movably installed inside both the first moving rod and the second moving rod.

[0007] By adopting the above technical solution, by providing multiple sets of movable rods, second movable rods, first movable rods, first rotating rods, ratchets and pawls, when a worker uses this device to polish the headlight housing, after placing it inside the working box, rotating the first rotating rod can drive multiple sets of first movable rods and second movable rods to move and contact the headlight housing, perform certain extrusion and fixation on it. At the same time, during the rotation of the first rotating rod, through the transmission of components such as the transmission assembly and the second bevel gear, it will drive the scraping plates movably installed at both ends to move towards each other, cooperate with the first movable rods, thereby completing the fixation and limitation of the headlight housing. And components such as the ratchet and pawl can control the rotation direction and angle of the first rotating rod, so as to ensure that when the worker uses the polishing device to polish it, the overall position will not change, ensuring the polishing effect.

[0008] The present utility model is further configured such that the auxiliary assembly includes a movable rod, a first spring, a pressing block, a fixed rod and a movable groove. A movable rod is movably installed inside the first movable rod, and a pressing block is fixedly installed at one end of the movable rod. A first spring connected to the first movable rod and the pressing block is sleeved outside the movable rod, and one side end face of the pressing block is arranged in an arc shape. A fixed rod is fixedly installed inside the first movable rod, and a movable groove matching the fixed rod is formed inside the working box.

[0009] By adopting the above technical solution, the movably installed movable rod enables it to drive the pressing block to move inside the first movable rod. The end face of the pressing block is arranged in an arc shape, enabling it to better extrude and fix the headlight housing when contacting it. At the same time, the first spring will continuously apply an elastic force to the pressing block to prevent the pressing block from fitting more closely to the inner wall of the lamp cover when the worker rotates the first rotating rod, making the clamping more stable. The cooperation between the fixed rod and the movable groove can provide a certain support for the first movable rod and the second movable rod, and at the same time impose a certain limitation on them, ensuring that they can normally fix and limit the headlight housing.

[0010] The present utility model is further configured such that a second rotating rod is movably installed inside the working box, and a second bevel gear is fixedly installed in the middle of the second rotating rod. A first bevel gear is fixedly installed at one end of the first rotating rod. A fixing plate is fixedly installed inside the working box, and a transmission assembly meshing with the second bevel gear and the first bevel gear is movably installed inside the fixing plate.

[0011] By adopting the above technical solution, the movably installed second rotating rod enables it to rotate inside the working box. The fixedly installed second bevel gear drives the second rotating rod to rotate together when it is driven by the transmission assembly. Both the first bevel gear and the second bevel gear are meshed with the transmission assembly, so that when the first rotating rod rotates, it will drive the second rotating rod to rotate through the transmission assembly, eliminating the need to add a new power source to provide drive for the scraping plates.

[0012] The present utility model is further configured such that both ends of the second rotating rod are provided with threads, and a scraping plate is movably installed at one end of the second rotating rod, and a thread groove matching the threads is provided inside the scraping plate.

[0017] By adopting the above technical solution, the handle can facilitate the worker to more conveniently control the position of the first rotating rod. The movably installed pull rod enables the worker to pull the pull rod to control the ratchet pawl to release the restriction on the ratchet wheel. The second spring continuously applies an elastic force to the ratchet pawl to ensure that it continuously applies a restriction to the ratchet wheel, ensuring that it will not loosen during the fixation process and ensuring the grinding effect of the worker using the grinding equipment on the headlight housing.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] The utility model is provided with multiple sets of movable rods, second moving rods, first moving rods, first rotating rods, ratchets and pawls. When a worker uses the device to polish the headlight housing, after placing it inside the working box, the worker only needs to rotate the first rotating rod, which can drive multiple sets of first moving rods and second moving rods to move and contact the headlight housing, exerting a certain extrusion and fixation on it. At the same time, during the rotation of the first rotating rod, through the transmission of components such as the transmission assembly and the second bevel gear, the scraping plates movably installed at both ends thereof will be driven to move in opposite directions and cooperate with the first moving rods, thereby completing the fixation and restriction of the headlight housing. Moreover, components such as the ratchet and the pawl can control the rotation direction and angle of the first rotating rod, so as to ensure that when the worker uses the polishing device to polish it, the overall position will not change, ensuring the polishing effect.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0028] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0029] A headlight housing grinding device, as Figures 1-6 shown, includes a working box 1. One end of the working box 1 is movably installed with a grinding device 2, and a first rotating rod 3 is movably installed inside the working box 1. A gear 13 is fixedly installed in the middle of the first rotating rod 3. A first moving rod 4 is movably installed inside the working box 1, and the first moving rod 4 is symmetrically arranged in two groups. One ends of the two groups of first moving rods 4 are respectively installed with a first tooth plate 11 and a second tooth plate 12, and the first tooth plate 11 and the second tooth plate 12 are engaged with the gear 13. A second moving rod 5 is movably installed inside the working box 1, and a guide rod 14 is fixedly installed at one end of the second moving rod 5. A guide groove 15 matching the guide rod 14 is opened inside the first rotating rod 3. An auxiliary component for fixing the headlight housing is movably installed inside both the first moving rod 4 and the second moving rod 5. When a worker uses this device to grind the headlight housing, the worker only needs to place the headlight housing on the inner end face of the working box 1. The worker rotates the first rotating rod 3, and through components such as the first tooth plate 11, the second tooth plate 12, and the gear 13, the two groups of first moving rods 4 are driven to move towards each other. At the same time, components such as the guide groove 15 and the guide rod 14 drive the two groups of second moving rods 5 to move, so as to fix and limit the housing. During the movement, the extrusion block 8 first contacts the headlight housing. Cooperating with the specific arc shape of the extrusion block 8, it is ensured that the overall shape of the housing will not be affected when fixing the housing, thereby improving the overall working efficiency.

[0030] Please refer to Figure 1 - Figure 6, the auxiliary components include a movable rod 6, a first spring 7, a pressing block 8, a fixed rod 9 and a movable slot 10. The movable rod 6 is movably installed inside the first moving rod 4, and a pressing block 8 is fixedly installed at one end of the movable rod 6. A first spring 7 connected to the first moving rod 4 and the pressing block 8 is sleeved outside the movable rod 6, and one end face of the pressing block 8 is arranged in an arc shape. A fixed rod 9 is fixedly installed inside the first moving rod 4, and a movable slot 10 matching the fixed rod 9 is opened inside the working box 1. The movably installed movable rod 6 enables it to drive the pressing block 8 to move inside the first moving rod 4. The end face of the pressing block 8 is arranged in an arc shape, so that it can better press and fix the headlight housing when contacting it. At the same time, the first spring 7 will continuously apply an elastic force to the pressing block 8 to prevent the pressing block 8 from fitting more closely to the inner wall of the lamp cover when the worker rotates the first rotating rod 3, making the clamping more stable. The cooperation between the fixed rod 9 and the movable slot 10 can provide a certain support for the first moving rod 4 and the second moving rod 5, and at the same time impose a certain restriction on them to ensure that they can normally fix and restrict the headlight housing.

[0031] Please refer to Figure 1 - Figure 4 , a second rotating rod 20 is movably installed inside the working box 1, and a second helical gear 19 is fixedly installed in the middle of the second rotating rod 20. A first helical gear 16 is fixedly installed at one end of the first rotating rod 3.

The movably installed second rotating rod 20 enables it to rotate inside the working box 1. The fixedly installed second helical gear 19 enables it to drive the second rotating rod 20 to rotate together when driven by the transmission component 18. Both the first helical gear 16 and the second helical gear 19 are meshed with the transmission component 18, so that the first rotating rod 3 will drive the second rotating rod 20 to rotate through the transmission component 18 during the rotation process, eliminating the need to add a new power source and providing drive for the scraper 22.

[0032] Please refer to Figure 1 - Figure 4 , threads 21 are opened at both ends of the second rotating rod 20, and a scraper 22 is movably installed at one end of the second rotating rod 20. A thread groove matching the threads 21 is opened inside the scraper 22. The movably installed scraper 22 enables it to drive the scraper 22 to move when the second rotating rod 20 rotates, so as to fix and restrict the headlight housing or clean the inner end face of the working box 1.

[0033] Please refer to Figure 2 - Figure 4, one end of the working box 1 is fixedly installed with a limiting rod 23 for restricting the scraping plate 22, and a collecting groove 24 for discharging materials is opened inside the working box 1. Both the guiding groove 15 and the thread 21 are arranged in two groups in a mirror image. The limiting rod 23 can restrict the scraping plate 22 to prevent it from rotating together with the second rotating rod 20, ensuring that it can normally fix the headlight housing and clean the inner end face of the working box 1. The setting of the collecting groove 24 enables it to cooperate with the scraping plate 22 to push the waste chips generated by grinding into the inside of the collecting groove 24 and discharge them from the inside of the working box 1, facilitating subsequent cleaning. The guiding groove 15 and the thread 21 are both arranged in two groups in a mirror image, so that the second moving rod 5 and the scraping plate 22 move in opposite directions during rotation, thus achieving their respective purposes.

[0034] Please refer to Figure 5 , one end of the first rotating rod 3 is fixedly installed with a handle 25, one end of the working box 1 is fixedly installed with an extension block 26, and a pull rod 27 is movably installed inside the extension block 26. One end of the pull rod 27 is fixedly installed with a pawl 28, and a second spring 30 connected to the extension block 26 and the pawl 28 is sleeved outside the pull rod 27. One end of the first rotating rod 3 is fixedly installed with a ratchet wheel 29 matching the pawl 28. The handle 25 can facilitate the worker to more conveniently control the position of the first rotating rod 3. The movably installed pull rod 27 enables the worker to pull the pull rod 27 to control the pawl 28 to release the restriction on the ratchet wheel 29. The second spring 30 will continuously apply an elastic force to the pawl 28 to ensure that it continuously applies a restriction to the ratchet wheel 29, ensuring that it will not loosen during the fixing process and ensuring the grinding effect of the worker using the grinding device 2 on the headlight housing.

[0035] The working principle of the present utility model is as follows: When a worker uses this device to polish the headlight housing, the worker only needs to place the headlight housing on the inner end face of the working box 1. The worker rotates the first rotating rod 3, and through components such as the first toothed plate 11, the second toothed plate 12, and the gear 13, drives the two groups of first moving rods 4 to move towards each other. At the same time, components such as the guiding groove 15 and the guiding rod 14 drive the two groups of second moving rods 5 to move, so as to fix and limit the housing. During the movement, the extrusion block 8 first contacts the headlight housing. Matching with the specific arc shape of the extrusion block 8, it is ensured that the overall shape of the housing will not be affected when the housing is fixed. And during the rotation of the first rotating rod 3, the first helical gear 16 will be driven to rotate together. Through the transmission assembly 18 and the second helical gear 19, the second rotating rod 20 is driven to rotate, so that the scraping plates 22 movably installed at both ends move towards each other and cooperate with the first moving rods 4 to fix the headlight housing. The worker pulls the polishing device 2 to polish the headlight housing. During the rotation of the first rotating rod 3, the pawl 28 will continuously receive the elastic force of the second spring 30 to limit the ratchet wheel 29, preventing the first rotating rod 3 from rotating during the polishing process, thus affecting the fixation, ensuring that the position of the headlight housing will not shift, ensuring the polishing effect. After the polishing is completed, the worker pulls the pull rod 27 to control all components to reset. During the reset process of the scraping plate 22, the waste chips generated by the polishing will be pushed into the collection groove 24, helping the worker to clean the end face of the working box 1 and improving the overall working efficiency.
