Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal curved surface inspection tools, and in particular relates to a sheet metal curved surface inspection tool for an automobile battery pack. Background Art

[0002] The sheet metal of an automotive battery pack refers to the metal parts used to wrap and fix automotive batteries. When sheet metal parts are produced and processed, it is necessary to use detection tools to detect surface defects on the surface of the sheet metal parts to avoid the impact of surface defects on the processing during further processing of the sheet metal parts. However, when the existing equipment is in use, since sheet metal parts are metal parts, burrs are easily generated on the surface of the sheet metal during turning and milling, which are difficult to observe. As a result, when detecting surface defects, the detection results are easily affected by the burrs and produce data deviations. Therefore, it is necessary to use burr cleaning equipment to clean the burrs attached to the surface of the sheet metal parts.

[0003] Existing burr cleaning equipment for sheet metal parts is generally started by a motor, and the motor shaft drives the rotating shaft to rotate, so that the rotating wheel drives the connecting rod to perform a circular motion on the rotating wheel, thereby pushing the horizontal valve block on the connecting rod to slide on the connecting slider, thereby performing a left and right reciprocating motion, so that the friction rod on the horizontal moving pole on the horizontal valve block performs a left and right rapid friction on the power generation block, thereby generating power, which comes to the electromagnetic rod through the power connection module, so that the burr soft brush generates a magnetic field to absorb the scraped burrs, thereby cleaning the burrs adhered to the surface of the sheet metal. Although this method can clean the burrs adhered to the surface of the sheet metal, since this method involves the coordination and synchronous work of multiple mechanical moving parts, this makes the operation between these complex mechanical parts more complicated, which makes the burr removal more troublesome and greatly reduces the efficiency of burr removal. Utility Model Content

[0004] The purpose of the utility model is to provide a curved surface inspection tool for sheet metal parts of automobile battery packs to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a curved surface inspection fixture for sheet metal parts of an automobile battery pack, comprising:

[0006] A rack, wherein two sets of baffles are provided on the top of the rack;

[0007] A conveying plate is arranged on the surface of the frame and between the two groups of baffles for conveying the sheet metal parts for movement. A protective shell is arranged between the tops of the two groups of baffles. A cleaning component for cleaning burrs adhered to the surface of the sheet metal parts is arranged in the protective shell. The electromagnetic suction cup of the cleaning component is energized to adsorb the metal burrs adhered to the surface of the sheet metal parts, so that the metal burrs adhered to the surface can be dropped and collected into the cleaning box after the electromagnetic suction cup is powered off.

[0008] Preferably, the cleaning assembly includes a fan and a collecting bucket, the fan is arranged on the surface of the frame, the collecting bucket is arranged on one side of the protective shell, and the top of the protective shell is rotatably connected to a screw rod.

[0009] Preferably, one end of the fan is connected to the collecting bucket through a pipeline, the cleaning box is arranged on the surface of the frame and the other end of the fan is connected to the cleaning box through a connecting pipe.

[0010] Preferably, a motor is provided on the surface of the protective shell, and the rotating shaft of the motor rotates through the protective shell and is connected to the screw rod, and the top of the electromagnetic suction cup is connected to the surface of the screw rod through a screw nut.

[0011] Preferably, a guide rod is provided in the protective shell and at the top of the screw rod, the top of the electromagnetic suction cup is slidably sleeved on the surface of the guide rod, and a brush is provided at the bottom of the electromagnetic suction cup. The burrs on the surface of the sheet metal are moved by brushing the brush, so that the contact area between the bottom of the electromagnetic suction cup and the burr surface can be increased, thereby increasing the effect of adsorbing the burrs.

[0012] Preferably, a connecting frame is provided on the surface of the two groups of baffles and located on one side of the protective shell, a threaded rod is provided on the top of the connecting frame, and one end of the threaded rod is rotated to pass through a threaded cylinder provided in the middle of the connecting frame.

[0013] Preferably, one end of the threaded rod located in the connecting frame is rotatably connected to a cleaning plate, and sliding rods are provided on both sides of the top of the cleaning plate, and one end of the sliding rod slides through the connecting frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The sheet metal with burrs adhered to it is clamped and fixed on the surface of the conveyor plate by a clamp, and the threaded rod is rotated in the threaded barrel so that the threaded rod drives the cleaning plate to move downward, thereby adjusting the height of the cleaning plate according to the thickness of the sheet metal. Then the conveyor plate is controlled to work, and the conveyor plate can drive the sheet metal to move. When the moving sheet metal contacts the cleaning plate, the grinding plate at the bottom of the cleaning plate can grind off the burrs firmly adhered to the surface of the sheet metal, thereby avoiding the difficulty of cleaning the firmly adhered burrs on the surface of the sheet metal during subsequent cleaning.

[0016] (2) After being polished by the polishing plate, the sheet metal part is moved into the protective shell under the continuous conveyance of the conveyor plate. At this time, the motor is started and the electromagnetic suction cup is energized to generate magnetic force. The output shaft of the motor drives the screw to rotate, and the screw drives the electromagnetic suction cup to move back and forth on the surface of the screw to magnetically absorb the burrs adhered to the surface of the sheet metal part. After the electromagnetic suction cup has magnetically absorbed the burrs on the surface of the sheet metal part, the electromagnetic suction cup can be moved above the collection bucket, and the power of the electromagnetic suction cup is cut off to make the electromagnetic suction cup lose its magnetic force. The burrs on the surface of the electromagnetic suction cup fall into the collection bucket after losing magnetic attraction. At this time, the fan draws the burrs in the collection bucket into the connecting pipe, and enters the cleaning box from the connecting pipe, thereby completing the burr cleaning on the surface of the sheet metal part. The operation is relatively simple, and after cleaning the burrs, the burrs are collected in the cleaning box, which is convenient for centralized collection and cleaning later.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 A curved surface inspection fixture for sheet metal parts of an automobile battery pack shown in the figure comprises:

[0023] A frame 1, wherein two sets of baffles 2 are provided on the top of the frame 1;

[0024] A conveying plate 3 is provided on the surface of the frame 1 and is located between the two groups of baffles 2 for conveying the sheet metal 4 for movement. A protective shell 5 is provided between the tops of the two groups of baffles 2. A cleaning component 6 for cleaning burrs adhered to the surface of the sheet metal 4 is provided in the protective shell 5. The electromagnetic suction cup 7 of the cleaning component 6 is energized to adsorb the metal burrs adhered to the surface of the sheet metal 4, so that the metal burrs adhered to the surface can be dropped and collected into the cleaning box 9 after the electromagnetic suction cup 7 is powered off.

[0025] The cleaning assembly 6 includes a fan 10 and a collecting bucket 11. The fan 10 is arranged on the surface of the frame 1, and the collecting bucket 11 is arranged on one side of the protective shell 5. The top of the protective shell 5 is rotatably connected with a screw rod 12.

[0026] One end of the fan 10 is connected to the collecting bucket 11 through a pipeline, and the cleaning box 9 is arranged on the surface of the frame 1 and the other end of the fan 10 is connected to the cleaning box 9 through a connecting pipe 13. The fan 10 draws the burrs in the collecting bucket 11 into the connecting pipe 13, and enters the cleaning box 9 from the connecting pipe 13, thereby collecting the burrs through the cleaning box 9.

[0027] A motor 14 is disposed on the surface of the protective shell 5 , and a rotating shaft of the motor 14 rotates through the protective shell 5 and is connected to the screw rod 12 . The top of the electromagnetic chuck 7 is connected to the surface of the screw rod 12 through a screw nut.

[0028] A guide rod 15 is provided inside the protective shell 5 and at the top of the screw rod 12. The top of the electromagnetic suction cup 7 is slidably sleeved on the surface of the guide rod 15. A brush 16 is provided at the bottom of the electromagnetic suction cup 7. The guide rod 15 guides the moving direction of the electromagnetic suction cup 7 to enhance the stability of the movement of the electromagnetic suction cup 7.

[0029] A connecting frame 17 is provided on the surface of the two groups of baffles 2 and located on one side of the protective shell 5. A threaded rod 18 is provided on the top of the connecting frame 17, and one end of the threaded rod 18 rotates to penetrate a threaded tube 19 provided in the middle of the connecting frame 17. One end of the threaded rod 18 located in the connecting frame 17 is rotatably connected to a cleaning plate 20. Slide rods 21 are provided on both sides of the top of the cleaning plate 20, and one end of the slide rod 21 slides through the connecting frame 17. The threaded rod 18 is rotated in the threaded tube 19, so that the threaded rod 18 drives the cleaning plate 20 to move downward. When the moving sheet metal 4 contacts the cleaning plate 20, the grinding plate 22 at the bottom of the cleaning plate 20 can grind off the burrs firmly adhered to the surface of the sheet metal 4.

[0030] The automobile battery pack sheet metal curved surface inspection fixture clamps and fixes the sheet metal 4 with burrs on the surface of the conveying plate 3 through a clamp, and screws the threaded rod 18 to rotate in the threaded cylinder 19, so that the threaded rod 18 drives the cleaning plate 20 to move downward, thereby adjusting the height of the cleaning plate 20 according to the thickness of the sheet metal 4, and then controls the conveying plate 3 to work. The conveying plate 3 can drive the sheet metal 4 to move. When the moving sheet metal 4 contacts the cleaning plate 20, the grinding plate 22 at the bottom of the cleaning plate 20 can grind off the burrs firmly adhered to the surface of the sheet metal 4, so as to avoid the difficulty of cleaning the firmly adhered burrs on the surface of the sheet metal 4 during subsequent burr cleaning.

[0031] The sheet metal part 4 polished by the polishing plate 22 is moved into the protective shell 5 under the continuous conveyance of the conveying plate 3 and the conveying plate 3 is stopped. At this time, the motor 14 is started and the electromagnetic suction cup 7 is energized to generate magnetic force. The output shaft of the motor 14 drives the screw rod 12 to rotate, and the screw rod 12 drives the electromagnetic suction cup 7 to reciprocate back and forth on the surface of the screw rod 12 to magnetically absorb the burrs adhered to the surface of one end of the sheet metal part 4 in the protective shell 5. After the magnetic absorption is completed, the conveying plate 3 can be started again to make the conveying plate 3 continue to convey the subsequent sheet metal part 4 that has not been cleaned into the protective shell 5 and clean it through the electromagnetic suction cup 7. After cleaning one side of the sheet metal part 4, the sheet metal part 4 can be turned over to the other side, and this operation is repeated for cleaning. After cleaning, the clamp is loosened to remove the sheet metal part 4 from the surface of the conveying plate 3, and the surface defects on the surface of the sheet metal part 4 are detected by the detection tool;

[0032] After the burrs on the surface of the sheet metal part 4 are magnetically attracted by the electromagnetic suction cup 7, the electromagnetic suction cup 7 can be moved above the collecting bucket 11, and the electromagnetic suction cup 7 is powered off and the fan 10 is started. After the electromagnetic suction cup 7 is powered off, the electromagnetic suction cup 7 loses its magnetic force, and the burrs on the surface of the electromagnetic suction cup 7 fall into the collecting bucket 11 after losing magnetic attraction. At this time, the fan 10 draws the burrs in the collecting bucket 11 into the connecting pipe 13, and enters the cleaning box 9 from the connecting pipe 13, thereby completing the burr cleaning on the surface of the sheet metal part 4. The operation is relatively simple and the burrs are collected by the cleaning box 9 after cleaning, so that when the burrs are collected and cleaned in a centralized manner at a later time, the sealed door hinged on the surface of the cleaning box 9 can be opened to clean the burrs collected in the cleaning box 9, which is more convenient.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
