[0002] With the continuous expansion of the electric vehicle market, the demand for electric vehicle accessories is also increasing day by day. As a commonly used material in electric vehicle accessories, such as body covers, battery pack housings, etc., thin plates require a large number of punching operations during the production process to meet the needs of assembly, heat dissipation, wiring layout, etc., thus promoting the development of thin plate punching machines. In the past processing of automotive accessories, manual operation was relatively common for thin plate punching. Workers used ordinary drilling tools to punch holes one by one, with low efficiency and it was difficult to ensure the accuracy and consistency of the holes. Although laser punching has high precision, the equipment cost is high and the requirements for operators are also high.

[0003] Currently, during laser cutting, there is a lack of control over the hole angle, and when chamfering the hole edge is required, additional equipment is often needed for processing. Summary of the Invention

When the connecting bottom plate moves downward, it drives the limiting slide rod to move downward. The downward movement of the limiting slide rod drives the limiting ring to descend and compress the first spring. The compression of the first spring provides a reverse pulling force to drive the connecting bottom plate to move upward. The upward movement of the connecting bottom plate drives the collecting assembly to move, so that the thin plate is squeezed and positioned by the collecting assembly and the clamping plate. The limiting slide bar and the collecting assembly sandwich the fixed slide way and slide. This not only realizes the extrusion positioning of the thin plate, but also due to the fixation of the limiting slide bar and the connecting bottom plate and the fixation of the connecting bottom plate and the collecting assembly, when positioning the thin plate, the limiting slide bar provides a pulling force, and through the fixing effect of the fixed slide way, a tangential force support is provided for the thin plate. In addition to the elastic force directly provided by the first spring for positioning, the collecting assembly drives the limiting slide bar to generate a tangential force to drive the side of the limiting slide bar to rub against the fixed slide way, thereby enhancing the extrusion force on the thin plate, ensuring the stability of the thin plate during punching, and thus improving the punching accuracy.

Start the electric screw rod, and the electric screw rod drives the punching bottom plate to rise or fall. The spring slide bar provides an upward supporting force for the punching bottom plate to facilitate the reset of the punching bottom plate.

The electric rotary table descends to drive the adjusting frame to descend. The adjusting frame descends to drive the sliding frame to descend. The sliding frame descends to drive the grinding device to descend. When the grinding device contacts the top of the thin plate, it drives the sliding frame to move upward. The sliding frame moves upward to drive the first rack to move upward and compress the spring telescopic rod. The first rack moves upward to drive the first gear to rotate. The first gear rotates to drive the laser emitter to rotate, so as to deflect the laser, and thus process an arc-shaped hole. When the adjusting frame rises, the pressure inside the spring telescopic rod is released, so as to push the sliding frame downward, so that the sliding frame returns to its original position, and the moving distance of the sliding frame is limited by the second slide. The processing of chamfers with different angles at the hole edges is realized according to the rising and falling distances.

[0013] Preferably, the grinding device includes a grinding bottom plate. A fixing frame is fixedly connected to the bottom of the grinding bottom plate.

[0014] The present invention provides a thin plate punching machine for processing electric vehicle accessories. It has the following beneficial effects:

[0015] 1. For this thin plate punching machine for processing electric vehicle accessories, when the connecting bottom plate moves downward, it drives the limiting slide rod to move downward. The downward movement of the limiting slide rod drives the limiting ring to descend and compress the first spring. The compression of the first spring provides a reverse pulling force to drive the connecting bottom plate to move upward. The upward movement of the connecting bottom plate drives the collecting assembly to move, so that the thin plate is squeezed and positioned by the collecting assembly and the clamping plate. The fixing slideway is clamped between the limiting slide bar and the collecting assembly and slides. This not only realizes the squeezing and positioning of the thin plate, but also, due to the fixation of the limiting slide bar and the connecting bottom plate and the fixation of the connecting bottom plate and the collecting assembly, when positioning the thin plate, the limiting slide bar provides a pulling force, and through the fixing effect of the fixing slideway, a tangential force support is provided for the thin plate. In addition to the elastic force directly provided by the first spring for positioning, the collecting assembly drives the limiting slide bar to generate a tangential force to drive the limiting slide bar to rub against the side of the fixing slideway, thereby enhancing the squeezing force on the thin plate, ensuring the stability of the thin plate during punching, and thus improving the punching accuracy.

[0016] 2. The thin plate punching machine for processing electric vehicle accessories is provided with an arc-shaped design of the second arc-shaped plate, which reduces the reflection of the metal jet on the plane. Under the setting of the arc surface angle, the metal jet is concentratedly reflected to the center position of the second arc-shaped plate, so as to centrally process the metal jet. The protection plate is used to protect the exhaust fan, and the guide plate guides the thin plate, so as to facilitate the introduction of the thin plate. Start the exhaust fan, and the rotation of the exhaust fan drives nitrogen to pass through the inside of the exhaust fan and reach the side of the air partition through the inclined ventilation pipe. Due to the different densities of nitrogen and the metal jet, the metal jet gradually cools during the movement and is concentrated into the inside of the collection box under the action of gravity, so as to collect the metal jet. The arc-shaped pipe is arranged towards the inside of the inclined ventilation pipe to prevent the metal jet from passing through the inside of the arc-shaped pipe. Nitrogen flows through the arc-shaped pipe after gravity separation, enters the inside of the communication pipe through the air box and is released through the side of the porous pipe. When punching, nitrogen is directly ejected from two directions onto the surface of the thin plate, so as to provide gas protection during cutting. The connector replenishes nitrogen to reduce the participation of air. When holes are punched on the surface of the thin plate, the exhaust fan drives nitrogen to flow, so as to form a negative pressure between the thin plate and the top of the first arc-shaped plate. When the holes are punched, nitrogen directly flows downward from the holes, so as to process the metal jet and provide nitrogen protection for the cutting part, thereby improving the quality of punching.

[0017] 3. The thin plate punching machine for processing electric vehicle accessories is provided with a first telescopic rod and an electric slide rail that cooperate to move, so as to realize the bidirectional movement of the electric rotating table, and punch holes at different positions of the thin plate. Start the electric screw, and the electric screw drives the punching bottom plate to rise or fall. The spring slide rod provides an upward supporting force for the punching bottom plate to facilitate the reset of the punching bottom plate. The first slide bar is used for the auxiliary positioning of the punching bottom plate. When the punching bottom plate drives the electric slide rail to descend, the descent of the electric slide rail drives the electric rotating table to descend. The descent of the electric rotating table drives the adjustment frame to descend. The descent of the adjustment frame drives the sliding frame to descend. The descent of the sliding frame drives the grinding device to descend. When the grinding device touches the top of the thin plate, it drives the sliding frame to move upward. The upward movement of the sliding frame drives the first rack to move upward and compresses the spring telescopic rod. The upward movement of the first rack drives the first gear to rotate. The rotation of the first gear drives the laser emitting head to rotate, so as to deflect the laser and process the arc-shaped hole. When the adjustment frame rises, the pressure inside the spring telescopic rod is released, so as to push the sliding frame downward, so that the sliding frame returns to its original position, and the movement distance of the sliding frame is limited by the second slide bar. The processing of chamfers with different angles at the hole edge is realized according to the rising and falling distances.

[0018] 4. The thin plate punching machine for processing electric vehicle accessories is provided with a grinding bottom plate that moves downward to drive the fixing frame to move downward. The downward movement of the fixing frame drives the first polishing roller to move downward. The downward movement of the first polishing roller drives the connecting rod to move downward. The downward movement of the connecting rod drives the second polishing roller to move downward. The second polishing roller first contacts the surface of the thin plate and drives the second polishing roller to move upward under the action of the thin plate surface. The upward movement of the second polishing roller drives the connecting rod to rotate around the second gear, so that the fourth gear meshes with the braking rack to brake the fourth gear. When cutting, the second polishing roller stops the passive rotation of the second polishing roller and the first polishing roller through the meshing between gears, so that the second polishing roller and the first polishing roller polish the edge of the punched hole, thereby removing the processing burrs and improving the processing quality.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a thin plate punching machine for processing electric vehicle accessories, including a robotic arm 1, a connecting bracket 2 is fixedly connected to the side of the robotic arm 1, a fixing device 3 is fixedly connected to the side of the connecting bracket 2 away from the robotic arm 1, and a punching device 4 is fixedly connected to the top of the fixing device 3;

[0030] The robotic arm 1 supports the movement of the device. The connecting bracket 2 is used for connection. The fixing device 3 is used to fix the thin plate and provide gas protection. The punching device 4 cuts and punches the thin plate and polishes the periphery of the punched hole, thereby increasing the flatness around the hole, which is beneficial for subsequent installation. The fixing device 3 provides gas protection during cutting and separates the gas from the welding slag, and the gas is reused. Since nitrogen does not react with metals during welding, nitrogen can be reused.

[0031] The fixing device 3 includes a fixing base plate 301. A clamping plate 302 is fixedly connected to the side of the fixing base plate 301. A fixing slideway 303 is fixedly connected to the bottom of the clamping plate 302. A connecting component 304 is slidably connected to the side of the fixing slideway 303. A collecting component 305 is fixedly connected to the top of the connecting component 304. A separating component 306 is fixedly connected to the bottom of the collecting component 305. One side of the fixing base plate 301 away from the clamping plate 302 is fixedly connected to the side of the connecting bracket 2.

[0032] The connecting component 304 includes a connecting base plate 3041. Limiting slide bars 3042 are fixedly connected to both sides of the top of the connecting base plate 3041. A limiting slide rod 3043 is fixedly connected to the center position of the top of the connecting base plate 3041. A limiting slide sleeve 3044 is sleeved and slidably connected to the side of the limiting slide rod 3043. A first spring 3045 is fixedly connected to the top of the limiting slide sleeve 3044. A limiting ring 3046 is fixedly connected to the top of the limiting slide sleeve 3044. The top of the first spring 3045 is fixedly connected to the bottom of the limiting ring 3046. The side of the limiting slide sleeve 3044 is fixedly connected to the side of the fixing slideway 303. One side of the top of the connecting base plate 3041 is fixedly connected to the bottom of the collecting component 305.

[0033] The robotic arm 1 drives the fixing device 3 to move, clamping a thin plate in the gap between the collecting component 305 and the clamping plate 302. During the insertion process of the thin plate, the thin plate drives the collecting component 305 to move downward. The downward movement of the collecting component 305 drives the connecting bottom plate 3041 to move downward. The downward movement of the connecting bottom plate 3041 drives the limiting slide bar 3043 to move downward. The downward movement of the limiting slide bar 3043 drives the limiting ring 3046 to descend and compress the first spring 3045. The compression of the first spring 3045 provides a reverse pulling force to drive the connecting bottom plate 3041 to move upward. The upward movement of the connecting bottom plate 3041 drives the collecting component 305 to move, so that the thin plate is squeezed and positioned by the collecting component 305 and the clamping plate 302. The fixing slideway 303 is clamped between the limiting slide bar 3042 and the collecting component 305 and slides. This not only realizes the squeezing and positioning of the thin plate, but also, due to the fixation of the limiting slide bar 3042 and the connecting bottom plate 3041 and the fixation of the connecting bottom plate 3041 and the collecting component 305, a pulling force is provided by the limiting slide bar 3042 during the positioning of the thin plate, and a tangential force support is provided for the thin plate through the fixing effect of the fixing slideway 303. In addition to the elastic force directly provided by the first spring 3045 for positioning, the collecting component 305 drives the limiting slide bar 3042 to generate a tangential force to drive the limiting slide bar 3042 to rub against the side of the fixing slideway 303, thereby enhancing the squeezing force on the thin plate, ensuring the stability of the thin plate during punching, and thus improving the punching accuracy.

[0034] Please refer to Figures 1 - 5 As shown in the figure, the present invention provides a technical solution: the collecting component 305 includes a first arc-shaped plate 3051. A ventilation hole 3052 is opened at the top of the first arc-shaped plate 3051. A second arc-shaped plate 3053 is fixedly connected to the top of the first arc-shaped plate 3051. A through hole 3054 is opened at the top of the second arc-shaped plate 3053. A guide plate 3055 is fixedly connected to the side of the second arc-shaped plate 3053. A protection plate 3056 is fixedly connected to the bottom of the guide plate 3055. A connecting plate 3057 is fixedly connected to the bottom of the first arc-shaped plate 3051. The bottom of the connecting plate 3057 is fixedly connected to the top of the connecting bottom plate 3041. The bottom of the ventilation hole 3052 is communicated with the top of the separation component 306.

[0035] The separation component 306 includes an air extraction fan 3061. The bottom of the air extraction fan 3061 is communicated with an inclined ventilation pipe 3062. The inner wall of the inclined ventilation pipe 3062 is fixedly connected with an air partition 3063. The side of the air partition 3063 is communicated with an arc-shaped pipe 3064. The side of the inclined ventilation pipe 3062 is communicated with an air box 3065. The inner wall of the air box 3065 is slidably connected with a collection box 3066. The side of the air box 3065 is communicated with a connecting pipe 3067. One end of the connecting pipe 3067 away from the air box 3065 is communicated with a porous pipe 3068. The side of the air box 3065 is communicated with a connector 3069. The connector 3069 is communicated with an external nitrogen supply device. The side of the porous pipe 3068 is fixedly connected with the side of the clamping plate 302. The top of the air extraction fan 3061 is fixedly connected with the bottom of the first arc-shaped plate 3051.

[0036] During cutting, the metal jet generated by cutting enters the ventilation hole 3052 through the through hole 3054 and reaches the inside of the air extraction fan 3061. Under the arc-shaped design of the second arc-shaped plate 3053, the reflection of the metal jet on the plane is reduced, and it is centrally reflected to the center position of the second arc-shaped plate 3053 at the angle of the arc surface, so as to centrally process the metal jet. The protection plate 3056 is used to protect the air extraction fan 3061, and the guide plate 3055 guides the thin plate, so as to facilitate the introduction of the thin plate. Start the air extraction fan 3061. The rotation of the air extraction fan 3061 drives nitrogen to pass through the inside of the air extraction fan 3061 and reach the side of the air partition 3063 through the inclined ventilation pipe 3062. Due to the different densities of nitrogen and the metal jet, the metal jet gradually cools during movement and is concentrated into the inside of the collection box 3066 under the action of gravity, so as to collect the metal jet. The arc-shaped pipe 3064 is arranged towards the inside of the inclined ventilation pipe 3062, so as to prevent the metal jet from passing through the inside of the arc-shaped pipe 3064. Nitrogen flows through the arc-shaped pipe 3064 after gravity separation, enters the inside of the connecting pipe 3067 through the air box 3065 and is released through the side of the porous pipe 3068. During punching, nitrogen is directly sprayed on the surface of the thin plate from two directions, so as to carry out gas protection during cutting. The connector 3069 replenishes nitrogen, so as to reduce the participation of air. When holes are punched on the surface of the thin plate, the air extraction fan 3061 drives nitrogen to flow, so as to form a negative pressure between the thin plate and the top of the first arc-shaped plate 3051. When holes are punched, nitrogen directly flows downward from the holes, so as to process the metal jet and carry out nitrogen protection on the cutting part, thereby improving the quality of punching.

The first rack 4076 moves upward and drives the first gear 4073 to rotate. The first gear 4073 rotates and drives the laser emitter 4077 to rotate, thus deflecting the laser, so as to process an arc-shaped hole. When the adjustment frame 4072 rises, the pressure inside the spring telescopic rod 4078 is released, thus pushing the sliding frame 4074 downward, so that the sliding frame 4074 returns to its original position, and the moving distance of the sliding frame 4074 is limited by the second slide bar 4075. The processing of chamfering the hole edge at different angles is realized according to the rising and falling distances.

[0040] Please refer to Figures 1 - 8 As shown in the figure, the present invention provides a technical solution: the grinding device 408 includes a grinding bottom plate 4081. A fixed frame 4082 is fixedly connected to the bottom of the grinding bottom plate 4081. A first polishing roller 4083 is rotatably connected to the side of the fixed frame 4082. A connecting rod 4084 is sleeved and rotatably connected to the rotating shaft of the first polishing roller 4083. A second gear 4085 is fixedly connected to a part of the rotating shaft of the first polishing roller 4083 on one side of the connecting rod 4084. A third gear 4086 is meshed with the side of the second gear 4085. A fourth gear 4087 is meshed with the side of the third gear 4086 away from the second gear 4085. A second polishing roller 4088 is rotatably connected to the side of the fourth gear 4087. The rotating shaft of the second polishing roller 4088 penetrates the side of the connecting rod 4084 and is rotatably connected to the connecting rod 4084. A braking rack 4089 adapted to the fourth gear 4087 is fixedly connected to the bottom of the grinding bottom plate 4081. The top of the grinding bottom plate 4081 is fixedly connected to the bottom of the sliding frame 4074.

[0041] During the process that the grinding base plate 4081 moves downward under the drive of the sliding frame 4074, the downward movement of the grinding base plate 4081 drives the fixed frame 4082 to move downward, the downward movement of the fixed frame 4082 drives the first polishing roller 4083 to move downward, the downward movement of the first polishing roller 4083 drives the connecting rod 4084 to move downward, the downward movement of the connecting rod 4084 drives the second polishing roller 4088 to move downward, the second polishing roller 4088 first contacts the surface of the thin plate, and drives the second polishing roller 4088 to move upward under the action of the thin plate surface. The upward movement of the second polishing roller 4088 drives the connecting rod 4084 to rotate around the second gear 4085, so that the fourth gear 4087 meshes with the brake rack 4089 to brake the fourth gear 4087. During cutting, the second polishing roller 4088 stops the passive rotation of the second polishing roller 4088 and the first polishing roller 4083 through the meshing between gears, so that the second polishing roller 4088 and the first polishing roller 4083 polish the edge of the punched hole, thereby removing the machining burrs and improving the machining quality.
