Description

Technical Field

[0001] The utility model belongs to the technical field of battery box spraying processing devices, and specifically relates to a battery box processing positioning tooling. Background Technique

[0002] A battery box is a shell framework for protecting a battery pack, which can protect the battery pack from external environment infringements, such as rain, dust, oxidation, corrosion, etc., and at the same time avoid battery short - circuit and thermal runaway, thereby improving the safety and reliability of the battery components.

[0003] In order to improve the uniformity and accuracy during spraying and reduce the occurrence of phenomena such as movement or rotation during the spraying process, resulting in waste of paint and uneven coating, most battery boxes will be clamped on both sides by fixtures during the spraying process.

[0004] When the fixture clamps both sides of the battery box, the contact points between the fixture and the battery box will block the spray gun or nozzle of the spraying equipment, easily causing the area where the fixture clamps the box to be difficult to be directly sprayed, thus requiring subsequent touch - up painting work, which is not only time - consuming and laborious, but also easily affects the quality and uniformity of the coating.

[0027] During operation, by inserting the plug rod 7 into the screw holes or other holes opened at the four corners of the edge of the battery case, starting the electric push rod 8, its output end pushes the conical block 9 to move upward. Due to the inclined design of the surface of the conical block 9 and under the guiding action of the sleeve frame 13, multiple groups of sliders will extend and move towards the inner wall of the plug rod 7, thereby driving the sliding plate 11 to extend from the inside of the plug rod 7 until it adapts to the hole size, completing the fixing work of the battery case. Moreover, the position of the plug rod 7 is fixed. When the battery case is fixed, similarly, the positioning work is also completed, and there is no need to use a fixture for clamping, thereby reducing problems such as uneven spraying caused by using a fixture for clamping, improving the spraying quality, and the output end of the servo motor 4 can drive the plug rod 7 to rotate, so as to facilitate spraying different surfaces of the battery case, and at the same time reduce the difficulty and complexity during subsequent installation caused by the spraying of the screw hole area.

[0030] Please refer to Figure 1 , Figure 4 , a limiting frame 22 is fixedly connected to the middle part on the top of the bottom plate 1, and a collecting box 21 is slidably and fittingly connected inside the limiting frame 22; magnets 23 that attract each other are respectively installed on one side of the collecting box 21 and the limiting frame 22; during operation, the collecting box 21 can collect the paint drips, splashes and oversprayed paint generated during the spraying process for subsequent recycling and reuse, improving the utilization rate of the paint and reducing the production cost. At the same time, the limiting frame 22 can quickly limit the reset position of the collecting box 21, and the mutually attracting magnets 23 can reduce the phenomenon that the collecting box 21 slides randomly, so as to improve the stability of the device.

[0031] Please refer to Figure 5 , a plurality of groups of second springs 24 are installed around the edge of one end of the support plate 6, and a buffer ring 25 is connected to the other end of the second springs 24; during operation, the second springs 24 can provide a certain elastic thrust when the inserting rod 7 contacts the shell to achieve a buffering effect.

[0032] Please refer to Figure 3 , a guiding block 26 is fixedly connected to the end of the inserting rod 7, and the guiding block 26 is semicircularly arranged; during operation, the circular guiding block 26 is used to improve the smoothness when the end of the inserting rod 7 is inserted into the screw hole.

[0033] Please refer to Figure 1 , a rubber pad is laid on the bottom of the bottom plate 1, and the rubber pad has the same shape as the bottom of the bottom plate 1; during operation, the rubber pad can increase the friction between the bottom of the bottom plate 1 and the ground, so as to reduce the phenomenon that the device slides on the ground during use and further improve the applicability of the device.

[0034] Working principle: By inserting the insertion rod 7 into the screw holes or other holes opened at the four corners of the edge of the battery case, the electric push rod 8 is started, and its output end pushes the conical block 9 to move upward. Due to the inclined design of the surface of the conical block 9 and under the guiding action of the sleeve frame 13, multiple groups of sliders will extend and move towards the inner wall of the insertion rod 7, thereby driving the sliding plate 11 to extend out from the inside of the insertion rod 7 until it adapts to the hole size, completing the fixation work of the battery case. And the position of the insertion rod 7 is fixed.

At the same time, the two limit rods 18 play the role of a strengthening rod, improving the strength of the device. And the limit block 20 is in the form of a threaded sleeve joint, which is convenient for separating from the three, so as to facilitate subsequent disassembly work; The collecting box 21 can collect the paint dripping, splashing and oversprayed paint generated during the spraying process, so as to be recycled and reused later, improving the utilization rate of the paint and reducing the production cost. At the same time, the limit frame 22 can quickly limit the reset position of the collecting box 21, and the mutually attracting magnets 23 can reduce the phenomenon of random sliding of the collecting box 21, so as to improve the stability of the device; The second spring 24 can provide a certain elastic thrust when the insertion rod 7 contacts the case, so as to achieve a buffering effect; Through the circular guiding block 26, the smoothness of the end of the insertion rod 7 when inserted into the screw hole can be improved; The rubber pad can increase the friction between the bottom of the bottom plate 1 and the ground, so as to reduce the phenomenon of sliding between the device and the ground during use, and further improve the applicability of the device.
