Description

Technical Field

[0001] This utility model belongs to the field of automotive lamp grinding and drilling technology, specifically relating to a rotating frame for automotive lamp grinding and drilling equipment. Background Technology

[0002] In the automotive lighting manufacturing industry, grinding and drilling are crucial steps in ensuring the assembly accuracy and performance of automotive lighting components. The rotating frame, as the core component of automotive lighting grinding and drilling equipment, undertakes important functions such as workpiece support, station switching, and motion guidance. Its performance directly affects processing accuracy, equipment energy consumption, service life, and operational safety. Traditional automotive lighting grinding and drilling equipment often uses sliding friction guiding mechanisms, coupled with single-station or simple dual-station designs. However, under long-term, high-frequency production, this has gradually revealed numerous problems.

[0003] Existing technologies have significant drawbacks: Firstly, the sliding friction guide structure has a high coefficient of friction, which not only increases the energy consumption of the drill disc rotation but also easily leads to rapid wear of the guide components, requiring frequent maintenance and replacement, thus significantly increasing operating costs. Furthermore, asymmetrical supports or worn guide components can easily cause the drill disc to rotate out of alignment, affecting machining accuracy and resulting in a high defect rate. Secondly, the station design is unreasonable, with high idle rates for single-station equipment and mutual interference in dual-station equipment due to a lack of effective isolation, leading to low equipment utilization. Simultaneously, insufficient protection and cleaning capabilities result in debris splashing, polluting the environment, threatening safety, and waste accumulation exacerbating positioning errors and equipment malfunctions.

[0004] In view of this, we propose a rotating frame for automotive headlight grinding and drilling equipment to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems of the prior art, which rely on sliding friction, resulting in high energy consumption, rapid wear, poor precision, unreasonable workstation design and insufficient protection, easy interference, pollution and failure, and high maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotating frame for a vehicle headlight grinding and drilling machine includes:

[0008] The drill bit assembly is rotatably mounted on top of the main frame of the break-in drill equipment;

[0009] The anti-top assembly is arranged in a ring at equal intervals on the running drill plate at the center of the main frame;

[0010] An angle divider installed inside the main frame passes through the break-in drill plate and connects to drill plate A on the drill disk assembly. The angle divider drives drill plate A to rotate, and the steel universal ball on the anti-top assembly cooperates with the annular guide groove at the bottom of drill plate A to limit and guide the sliding, thereby realizing the rotational movement of the drill disk assembly relative to the anti-top assembly in the fixed state.

[0011] Preferably, the drill plate assembly also includes two side panels located on both sides of the drill plate A, a partition fixed to the top of the drill plate A and the two side panels and dividing the drill plate A and the two side panels into two front and rear grinding stations, four directional roller mechanisms located at the four corners of the bottom of the drill plate A, and two dust collection hoppers located at the bottom of the drill plate A and on the front and rear sides of the partition. The drill plate is provided with circular through holes that are vertically corresponding to the two dust collection hoppers.

[0012] Preferably, the front and rear sides of the partition are fixedly connected to the drill plate A by four diagonal bracing plates.

[0013] Preferably, an annular wear-resistant plate is fixed to the inner bottom wall of the annular guide groove by hidden screws.

[0014] As a preferred option, each of the two grinding and drilling stations is provided with two limiting posts located on the top of the drilling platform A and symmetrically arranged on the left and right.

[0015] Preferably, the anti-top assembly includes an anti-top fixing seat fixed to the top of the running-in drill plate, a screw passing through the bottom of the running-in drill plate and threadedly connected to the anti-top fixing seat, a nut threaded onto the outer side of the screw and locking the anti-top fixing seat to the running-in drill plate, an anti-top support column inserted into the anti-top fixing seat and threadedly connected to the screw at its bottom, and a round pin passing through the anti-top support column and limited into the slot on the anti-top fixing seat, with a steel universal ball threadedly connected to the top of the anti-top support column.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are:

[0017] This invention transforms traditional sliding friction into rolling friction through the combination of a steel universal ball and an annular guide groove, fundamentally reducing the frictional resistance during drill rotation. This not only lowers the energy consumption of the equipment but also significantly reduces component wear, effectively extending the overall service life of the equipment and reducing the frequency of maintenance due to frictional wear.

[0018] The circularly arranged anti-top components of this invention provide uniform support for the drill disc. Combined with the precise guidance of the annular guide groove and the universal ball, it ensures the stability of the drill disc's rotation trajectory and avoids the shaking and offset problems caused by uneven force or guide deviation in traditional equipment. This provides a stable benchmark for the grinding and drilling of automotive lights and ensures the consistency of processing accuracy.

[0019] This utility model features a dual-grinding and drilling station that achieves physical isolation through a partition, which not only avoids mutual interference between the front and rear stations but also allows for rapid switching between stations via the rotation of the drill disc, thus improving equipment utilization. The dust collection hopper promptly collects waste materials, which not only improves the working environment but also reduces the impact of waste accumulation on processing and ensures the safety of operators.

[0020] The triangular support structure formed by the inclined brace plate of this utility model enhances the connection rigidity between the baffle and the drill plate, avoiding structural deformation; the annular wear-resistant plate can be replaced separately without replacing the entire drill plate, reducing maintenance costs and downtime; the modular design of the anti-top component facilitates height adjustment and component replacement, while the limiting column simplifies the workpiece positioning process. From structural stability to maintenance convenience, it is superior to traditional equipment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following combination Figures 1 to 7 This application will be described in further detail;

[0031] Example 1

[0032] This application discloses a rotating frame for a car headlight grinding and drilling equipment, including a drill plate assembly 1 and a counter-rotating assembly 4. The drill plate assembly 1 is rotatably mounted on the top of the main frame 3 of the grinding and drilling equipment 2. The counter-rotating assembly 4 is arranged in a ring at equal intervals on the grinding and drilling platform 5 at the center of the main frame 3. An angle divider 7 installed in the main frame 3 passes through the grinding and drilling platform 5 and is connected to the drilling platform A101 on the drill plate assembly 1. The angle divider 7 drives the drilling platform A101 to rotate. The steel universal ball 401 on the counter-rotating assembly 4 cooperates with the annular guide groove 102 at the bottom of the drilling platform A101 to limit and guide the sliding, thereby realizing the rotation of the drill plate assembly 1 relative to the counter-rotating assembly 4 in a fixed state.

[0033] The drill plate assembly 1 is rotatably mounted on the top of the main frame 3, and the anti-jacking assembly 4 is arranged in a ring at equal intervals on the running-in drill plate 5 at the center of the main frame 3. The drill plate A101 is driven to rotate by the angle divider 7. The steel universal ball 401 on the top of the anti-jacking assembly 4 cooperates with the annular guide groove 102 at the bottom of the drill plate assembly 1. The universal ball rolls in the guide groove, realizing the rotational movement of the drill plate assembly 1 relative to the fixed anti-jacking assembly 4 (essentially a guiding and limiting mechanism that converts sliding friction into rolling friction).

[0034] Rolling friction replaces sliding friction, reducing energy consumption and component wear during drill rotation and extending equipment life. The annular guide groove 102, in conjunction with the annularly arranged universal balls, ensures a stable drill rotation trajectory, preventing deviation and guaranteeing the precision of the headlight grinding process. The anti-rollover components 4 are evenly distributed in annular rings, providing uniform support to the drill disk and preventing swaying or deformation caused by uneven force during rotation.

[0035] The drill plate assembly 1 also includes two side panels 103 located on both sides of the drill plate A101, a partition 104 fixed to the top of the drill plate A101 and the two side panels 103 and dividing the drill plate A101 and the two side panels 103 into two front and rear grinding stations, four directional roller mechanisms 105 located at the four corners of the bottom of the drill plate A101, and two dust collection hoppers 106 located on the drill plate A101 and on the front and rear sides of the partition 104. The break-in drill plate 5 is provided with circular through holes 51 that are vertically corresponding to the two dust collection hoppers 106.

[0036] The side panels 103 provide protection for both sides of the drill plate A, enhancing the structural rigidity of the drill plate A and reducing lateral deformation during rotation.

[0037] The partition 104 achieves physical isolation between the two workstations, avoiding mutual interference between debris, workpieces or tools during processing at the front and rear workstations, and improving operational safety; it clearly delineates the work area, and by utilizing the characteristics of the rotating frame, the drill plate assembly 1 can rotate back and forth between the grinding and drilling workstation or the loading and unloading workstation, thereby improving equipment utilization.

[0038] The dust collection hopper 106 collects metal shavings, dust and other waste generated during the grinding and drilling process, and discharges them to the dust collection system outside the equipment through the lower circular through hole 51, keeping the workstation clean; avoiding the accumulation of waste that may affect processing accuracy or damage equipment parts, and reducing cleaning and maintenance costs.

[0039] The partition 104 is fixedly connected to the drill plate A101 on both the front and rear sides by four diagonal bracing plates 107. The diagonal bracing plates 107 form a triangular support structure (based on the principle of triangular stability), which greatly improves the connection rigidity between the partition 104 and the drill plate A, preventing the partition 104 from loosening or deforming during processing vibration or equipment rotation; the lateral forces (such as workpiece collisions or external operating forces) on the partition 104 are evenly transmitted to the drill plate A through the diagonal bracing plates 107, avoiding component damage caused by local stress concentration.

[0040] An annular wear-resistant plate 108 is fixed to the inner bottom wall of the annular guide groove 102 by concealed screws. The annular guide groove 102 is a key part that directly contacts the universal ball. The wear-resistant plate (usually made of high-hardness material, such as hardened steel) can withstand the friction and impact when the universal ball rolls, avoiding wear on the guide groove body and extending the service life of the drill plate assembly 1. The wear-resistant plate is fixed by concealed screws and can be replaced separately after wear, without replacing the entire drill plate A, reducing maintenance costs and downtime. The surface of the wear-resistant plate is flat and the hardness is uniform, ensuring the stability of the universal ball's rolling trajectory and maintaining the accuracy of the drill plate rotation.

[0041] Each of the two grinding and drilling stations is equipped with two symmetrically positioned limiting posts 109 located on the top of the drilling platform A101. The limiting posts 109 can be preset to their positions according to the size and shape of the automotive headlight workpiece, thus limiting the workpiece in the left and right directions and ensuring the consistency of the grinding and drilling position. When the workpiece is placed, it can be quickly aligned with the limiting posts 109, reducing positioning and adjustment time and improving processing efficiency.

[0042] The anti-jacking assembly 4 includes an anti-jacking fixing seat 402 fixed to the top of the running-in drill plate 5, a screw 403 passing through the bottom of the running-in drill plate 5 and threadedly connected to the anti-jacking fixing seat 402, a nut 404 threaded onto the outer side of the screw 403 and locking the anti-jacking fixing seat 402 onto the running-in drill plate 5, an anti-jacking support column 405 inserted into the anti-jacking fixing seat 402 and threadedly connected to the bottom of the screw 403, and a round pin 407 passing through the anti-jacking support column 405 and limited and locked into the locking position 406 on the anti-jacking fixing seat 402. A steel universal ball 401 is threadedly connected to the top of the anti-jacking support column 405. The steel universal ball 401 is a Yiheda model E-QDE02-16 steel universal ball 401.

[0043] The anti-jacking assembly 4 uses screws 403 and nuts 404 to lock the anti-jacking fixing seat 402 onto the break-in drill plate 5. The anti-jacking support column 405 is fixed inside the anti-jacking fixing seat 402 with screws 403. The round pin 407 passes through the anti-jacking support column 405 and engages with the locking position 406 of the anti-jacking fixing seat 402 to achieve axial limiting of the support column. The top steel universal ball 401 (model E-QDE02-16, Yiheda product) cooperates with the annular guide groove 102 of the drill plate assembly 1 to form a rolling support guide structure. Essentially, it achieves height-adjustable rigid support through threaded connection, anti-loosening limiting through round pin 407 and locking position 406, and rolling friction through universal ball.

[0044] Screw 403 is threadedly connected to the anti-top support column 405, allowing for fine-tuning of the omnidirectional ball's height to ensure that the top surfaces of the omnidirectional balls of multiple anti-top components 4 are on the same horizontal plane, guaranteeing smooth rotation of the drill disc. Nut 404 locks the anti-top fixing seat 402, and round pin 407 provides anti-loosening limit, preventing component loosening due to equipment vibration and ensuring support stability. The threaded connection and modular design facilitate component replacement and maintenance, reducing spare parts costs. The anti-top support column 405 provides rigid support, while the steel omnidirectional ball 401 simultaneously undertakes support and guiding functions, simplifying the structure while ensuring functional integrity. The rolling characteristics of the omnidirectional ball reduce friction and, in conjunction with the annular guide groove 102, achieve precise rotational guidance.

[0045] Example 2

[0046] This application discloses a rotating frame for a vehicle headlight grinding and drilling equipment, such as... Figures 1 to 7As shown, based on Embodiment 1, the directional roller mechanism 105 in Embodiment 1 is further described. The directional roller mechanism 105 includes two diaphragm cylinder mounting seats 61 fixed to the bottom of the running-in drill plate 5, a diaphragm clamping cylinder 62 located inside the two diaphragm cylinder mounting seats 61, a steel beam 63 located on the diaphragm clamping cylinder 62, roller seats 64 arranged at equal intervals on the top of the steel beam 63 and extending into the clearance hole 110 on the drill plate A101, roller bearings 66 rotatably connected to the roller seats 64 by a pin 65, two limiting rings 67 located at both ends of the steel beam 63, guide posts 68 passing through the limiting rings 67 and set on the steel beam 63, and a linear bearing 69 sleeved on the outer side of the guide post 68 and located at the bottom of the steel beam 63. The diaphragm clamping cylinder 62 has the model number 13292_EV-20_120-5. The diaphragm clamping cylinder 62 is equipped with an air connector 610, which has the model number PC4M5.

[0047] The core of the directional roller mechanism 105 is to achieve dynamic support for the workpiece by driving the roller bearing 66 through a diaphragm-type clamping cylinder 62 (model 13292_EV-20_120-5). When compressed air is introduced through the air connector 610 (PC4M5), the diaphragm of the diaphragm cylinder deforms to position the steel beam 63. When the workpiece is loaded, it is fed linearly through the roller bearing 66, reducing the loading and handling operations and making loading more convenient and labor-saving.

[0048] The rotating frame of the company's automotive headlight grinding and drilling equipment achieves stable rotation through the cooperation of the drill plate assembly 1 and the anti-top assembly 4: the steel universal balls 401 arranged in a ring on the anti-top assembly 4 and the annular guide groove 102 at the bottom of the drill plate assembly 1 form a rolling friction pair, which supports the weight of the drill plate and guides it to rotate around the center; the dual-station design of the drill plate assembly 1 can switch operations by rotation, the side plate 103 and the partition 104 provide protection and isolation, the dust collection hopper 106 collects waste and discharges it through the through hole, the inclined brace 107 and the wear-resistant plate respectively enhance the structural rigidity and reduce wear, the limit post 109 assists in the rapid positioning of the workpiece, and the threaded connection of the anti-top assembly 4 can adjust the height of the universal balls to ensure the support level.

[0049] By replacing sliding friction with rolling friction, rotational energy consumption and component wear are significantly reduced, extending equipment life while reducing maintenance needs. The cooperation between the annular guide groove 102 and the universal ball, along with the uniform support design, ensures the stability of the drill disk's rotation trajectory, preventing deviation and guaranteeing machining accuracy. The dual-station design with partitions 104 enables station isolation and rapid switching, avoiding mutual interference and improving equipment utilization. The side panels 103 and dust collection hopper 106 solve the problems of chip splashing and accumulation, improving the operating environment and reducing malfunctions.

[0050] The diagonal brace 107 enhances connection rigidity by utilizing triangular stability, preventing deformation caused by processing vibrations; the wear-resistant plate is removable and replaceable, reducing maintenance costs and downtime; the modular design of the anti-top assembly 4 facilitates adjustment and replacement, while the limit post 109 shortens workpiece positioning time. These improvements address the pain points of traditional equipment in terms of efficiency, accuracy, cost, and safety, thereby enhancing overall operational performance.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
