Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and in particular to a controller cover plate bending airtightness detection device. Background Technology

[0002] The controller's unique size and shape make it difficult for traditional bending machines to perform precise and reliable bending of its casing. Conventional bending equipment is often limited by workpiece size, bending radius, and the versatility of fixtures, leading to bending deviations, surface scratches, and even structural deformation in actual production, which in turn affects subsequent assembly quality and product lifespan. To overcome this bottleneck, a bending fixture specifically designed for this controller must be implemented.

[0003] Meanwhile, after assembly, the controller must meet stringent airtightness requirements. Airtightness is a key indicator for ensuring the internal electronic components of the controller are protected against moisture, dust, and corrosion, especially in the automotive industry where environmental adaptability is extremely demanding. Specialized tooling is also required when conducting airtightness tests on transmission controllers of different specifications and structures.

[0004] For example, CN217617010U, published on October 21, 2022, discloses a bending device for a cover plate of an automotive electric power steering ECU controller, including a base, a clamping mechanism, a left stamping mechanism, and a right stamping mechanism. The clamping mechanism is used to fix the controller and the cover plate on the base, and the left and right stamping mechanisms are used to bend and squeeze the protruding legs of the cover plate to make them fit tightly and fix them to the housing of the controller. Both the left and right stamping mechanisms include a stamping cylinder and two punches. After the aforementioned device mechanically bends the cover plate of the controller, it cannot quickly test the airtightness of the controller, resulting in poor practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a more practical controller cover plate bending airtightness testing device. This invention achieves bending assembly of the cover plate and controller through a pressure block and a guide block, and connects to an external testing device through a vent on the pressure block to achieve airtightness testing of the controller. By combining the bending and airtightness testing of the controller, it achieves greater practicality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a controller cover plate bending airtightness detection device, including a base plate and a pressure block arranged opposite to each other, the base plate is provided with a placement groove for placing the controller and the cover plate, the pressure block is provided with a guide block, and the pressure block is provided with a ventilation channel.

[0007] The pressure block is provided with a settling groove, and the side wall of the settling groove is provided with an extrusion wall. The extrusion wall is connected to the guide block, and the settling groove is connected to the detection channel.

[0008] The guide block is connected to the extrusion wall by bolts.

[0009] The outer end face of the extrusion wall is flush with the outer end face of the guide block.

[0010] The guide block has a first inclined surface on the side near the placement groove.

[0011] The base plate is provided with a guide groove that communicates with the placement groove, and the cover plate of the placement groove extends into the guide groove.

[0012] The shape of the guide groove is adapted to the shape of the extrusion wall.

[0013] The end of the guide groove wall is provided with a second inclined surface.

[0014] The settling tank is equipped with an elastic pad, and the elastic pad has flow holes that communicate with the air passage.

[0015] The elastic pad is a rubber pad.

[0016] The beneficial effects of this utility model are: The movement of the pressure block causes the guide block to bend the cover plate in the base plate, thereby assembling the cover plate and the controller. Gas is injected into the controller through the vent. After the internal pressure of the controller reaches the test requirements, the gas leakage is detected in real time by the pressure sensor to determine whether the workpiece meets the airtightness requirements. Combining the bending of the controller cover plate with airtightness detection makes it more practical, effectively reduces manufacturing costs, simplifies the production process, and improves the consistency of quality. The bending and assembly of the cover plate are achieved through the cooperation of the extrusion wall on the pressure block and the guide block. The connection between the cover plate and the controller is convenient and quick, and the rapid bending of the cover plate is ensured by the first inclined surface of the guide block. The airtightness of the controller during airtightness testing is increased by placing an elastic pad between the controller and the pressure block, thereby making the airtightness test results more accurate.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figure 1-2 As shown, the controller cover plate bending airtightness detection device includes a base plate 1 and a pressure block 2 arranged opposite each other. The pressure block 2 is driven by external force to bring the pressure block 2 and the base plate 1 closer to each other. Specifically, the pressure block 2 is connected to the piston of a hydraulic cylinder. The operation of the hydraulic cylinder causes the pressure block 2 to move towards the base plate 1. The base plate 1 is provided with a placement groove 4 for placing the controller 12 and the cover plate 3. The pressure block 2 is provided with a guide block 5 and a vent 6. Specifically, the cover plate 3 has a U-shaped cross section. The vent 6 is connected to an external air source. The air source delivers gas to the controller 12 through the vent 6. After the air pressure stabilizes, the change in air pressure inside the controller 12 is detected, thereby detecting the airtightness of the controller 12.

[0023] First, place the cover plate 3 in the placement groove 4 on the base plate 1, then place the controller 12 on the cover plate 3. Under the action of external force, the pressure block 2 moves close to the base plate 1 and is squeezed to the tilt by the guide block 5, separating the guide block 5 from the pressure block 2. The pressure block 2 is then driven to move again, so that the pressure block 2 bends the cover plate 3 and fixes it to the controller 12, thereby realizing the rapid assembly of the controller 12. After the pressure block 2 squeezes the cover plate 3, it maintains pressure. At this time, gas is injected into the controller 12 through the vent 6. After the internal pressure of the controller 12 reaches the test requirements, the gas leakage is detected in real time by the pressure sensor to determine whether the workpiece meets the airtightness requirements. Combining the bending of the controller with the airtightness test makes it more practical.

[0024] The pressure block 2 is provided with a sink 7, and the side wall of the sink 7 is provided with an extrusion wall 8. The extrusion wall 8 is connected to the guide block 5. The sink 7 is connected to the detection channel 6. The sink 7 is designed to house the controller 12, thereby facilitating the bending of the cover plate 3 by the extrusion wall 8 and the guide block 5, and ensuring a stable connection between the cover plate 3 and the controller 12.

[0025] The guide block 5 is connected to the extrusion wall 8 by bolts, thereby enabling the guide block 5 to be easily disassembled and assembled with the pressure block 2. After the guide block 5 bends the cover plate 3, it can be quickly removed. The extrusion wall 8 connects the cover plate 3 and the controller 12, making it more practical. Specifically, the guide block 5 is provided with a through hole for the bolt to pass through, and the pressure block 2 is provided with a threaded hole that mates with the bolt.

[0026] The outer end face of the extrusion wall 8 is flush with the outer end face of the guide block 5, thereby ensuring that after the guide block 5 is connected to the extrusion wall 8, the extrusion wall 8 and the guide block 5 can stably cooperate with the base plate 1, thereby performing the bending work on the cover plate 3.

[0027] The guide block 5 has a first inclined surface 501 on the side near the placement groove 4. When the guide block 5 moves to contact the outer wall of the cover plate 3, the guide block 5 moves down and the cover plate 3 is bent and tilted through the first inclined surface 501, which facilitates the subsequent pressing of the cover plate 3 by the extrusion wall 8.

[0028] The base plate 1 is provided with a guide groove 9 that communicates with the placement groove 4. The cover plate 3 of the placement groove 4 extends into the guide groove 9. The guide groove 9 guides the movement of the guide block 5 and the extrusion wall 8, thereby ensuring that the cover plate 3 is stably extruded by the guide block 5 and the extrusion wall 8.

[0029] The shape of the guide groove 9 is adapted to the shape of the extrusion wall 8, thereby enabling the extrusion wall 8 to move down into the guide groove 9 of the base plate 1. The extrusion wall 8 and the guide block 5 move precisely to contact the cover plate 3, thereby enabling the cover plate 3 to connect with the controller 12.

[0030] The end of the guide groove 9 is provided with a second inclined surface 901. The second inclined surface 901 facilitates the precise movement of the extrusion wall 8 and the guide block 5 into the guide groove 9 to contact the upper end of the cover plate 3, thereby realizing the bending operation of the cover plate 3.

[0031] The settling tank 7 is provided with an elastic pad 10, and the elastic pad 10 is provided with a flow hole 11 that communicates with the vent 6. The setting of the elastic pad 10 ensures the sealing when the pressure block 2 presses the controller 12, so that when the controller 12 performs air tightness testing, the gas stably enters the controller 12 through the vent 6 and the flow hole 11 on the elastic pad 10, thereby increasing the accuracy of the air tightness test results.

[0032] Specifically, the elastic pad 10 is a rubber pad, which achieves the sealing work after the pressure block 2 and the controller 12 are squeezed together by the elasticity of the rubber.

[0033] In summary, when using this application, the cover plate 3 is placed in the placement groove 4 on the base plate 1, and then the controller 12 is placed on the cover plate 3. The pressure block 2 moves closer to the base plate 1 under the action of external force, and the guide block 5 on the pressure block 2 moves toward the guide groove 9 on the base plate 1. When the guide block 5 moves downward, the cover plate 3 is bent and tilted through the first inclined surface 501. Separate the guide block 5 from the pressure block 2, place the elastic pad 10 on the upper end of the controller 12, and drive the pressure block 2 to move again. The movement of the pressure block 12 causes the extrusion wall 8 to move downward toward the guide groove 9 of the base plate 1. The extrusion wall 8 bends the cover plate 3 and connects it to the controller 12, thereby realizing the rapid assembly of the controller 12. After the pressure block 2 presses the cover plate 3 and maintains pressure, the wall of the sink 7 presses the elastic pad 10 at the upper end of the controller 12. Gas is injected into the controller 12 through the air passage 6. After the internal pressure of the controller 12 reaches the test requirements, the gas leakage is detected in real time by the pressure sensor to determine whether the workpiece meets the airtightness requirements.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
