Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning pressure plate processing technology, specifically a deburring device for automotive air conditioning pressure plate processing. Background Technology

[0002] In the field of automotive air conditioning plate processing, burrs are easily generated on the edges and front and back surfaces of the plate after it is formed. If they are not completely removed, they will affect the subsequent assembly accuracy and the stability of the air conditioning system. Therefore, deburring is a key process in plate processing.

[0003] A search revealed existing technology (application number: CN202021776375.4), which describes a "deburring device for processing automotive parts." While this device supports the grinding assembly with a fixed frame, positions the sheet metal using clamping blocks, and then removes burrs from the edges of the sheet metal using grinding wheels, it requires manual assistance for loading, positioning, and unloading the pressure plate. This lack of automation and continuous conveying and clamping results in low processing efficiency and fails to meet the demands of mass production of automotive parts. Furthermore, the clamping blocks employ a rigid fixed structure, with the clamping distance adjusted only by bolts. This prevents uniform force transmission, easily leading to pressure plate deformation or surface damage due to excessive clamping, or pressure plate displacement during processing due to loose clamping, affecting deburring accuracy. The device also lacks an effective pressure plate flipping mechanism, only capable of deburring a single surface or edge of the pressure plate, requiring manual flipping for secondary processing. This is not only cumbersome but also prone to incomplete burr removal due to positioning discrepancies, making it difficult to meet the stringent precision requirements of automotive air conditioning pressure plates.

[0004] Therefore, there is an urgent need for a deburring device for automotive air conditioning pressure plates that can achieve automated conveying and stable clamping of pressure plates, automatically flip the pressure plates to achieve multi-sided deburring, and has high processing accuracy and efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a deburring device for processing automotive air conditioning pressure plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a deburring device for processing automotive air conditioning pressure plates, comprising a base plate, the base plate being rectangular, and the lower surface of a support frame being bolted to the middle of the upper surface of the base plate; both sides of the upper surface of the base plate being connected to the two ends of a conveyor belt via columns, the conveyor belt being used for conveying the pressure plate; the upper end of the support frame being bolted to the periphery of a cross slide assembly; a clamping mechanism being provided inside the support frame for clamping the pressure plate; the lower surface of the clamping mechanism being connected to the upper surface of a lifting assembly, the lifting assembly being used for lifting the clamping mechanism; and positioning holes being provided above and below the periphery of the support frame for connecting other devices.

[0007] As a further description of the above technical solution:

[0008] The lower surface of the cross slide assembly is slidably connected to the upper end of the sliding block, the lower end of the sliding block is internally connected to the upper end of the mounting head, and the lower end of the sliding block is provided with a locking hole. The mounting head is used for mounting the tool.

[0009] As a further description of the above technical solution:

[0010] The lifting assembly includes a hydraulic rod. The lower fixed end of the hydraulic rod is connected to the inner bottom surface of the support frame, and the telescopic end of the hydraulic rod is connected to one side of the lower surface of the bearing plate. A guide rod is provided on the other side of the bearing plate, and the upper and lower ends of the guide rod are connected to one side of the support frame.

[0011] As a further description of the above technical solution:

[0012] The clamping mechanism includes a placement box, one side of which is rotatably connected to one side of the clamping box. An electric telescopic rod and a motor are installed inside the placement box. The telescopic end of the electric telescopic rod passes through the clamping box and is rotatably connected to one side of the push block.

[0013] As a further description of the above technical solution:

[0014] The push block is rotatably connected to one end of the push rod at both ends on the side away from the electric telescopic rod, and the other end of the push rod is rotatably connected to one end of the gear.

[0015] As a further description of the above technical solution:

[0016] The gear engages with one end of the rack on the side away from the push rod, and the other end of the rack away from the gear is connected to one end of the clamping rod. The clamping rod slides in the middle of the clamping box on the side away from the electric telescopic rod.

[0017] As a further description of the above technical solution:

[0018] The output shaft of the motor is connected to one end of the transmission shaft, and the other end of the transmission shaft is connected to the drive wheel. The drive wheel meshes with the driven wheel, and the middle of the driven wheel is connected to the clamping box near the electric telescopic rod by bolts.

[0019] This utility model has the following beneficial effects:

[0020] 1. The pressure plate is automatically conveyed by the conveyor belt, and the clamping rod driven by the electric telescopic rod and the gear and rack transmission stabilizes the pressure plate. Then, the cross slide group drives the tool to move precisely to remove burrs. The motor can also drive the clamping box to flip the pressure plate. The whole process does not require frequent manual intervention, effectively solving the problems of low efficiency and cumbersome operation of traditional manual deburring, and meeting the batch processing needs of automotive air conditioning pressure plates.

[0021] Second, the clamping mechanism achieves synchronous movement of the clamping rods through gear and rack transmission, resulting in uniform and stable clamping force, avoiding deviation or damage to the pressure plate during clamping. The lifting component uses hydraulic rods and guide rods to precisely adjust the height of the pressure plate, adapting to the processing needs of different cutting tools. At the same time, the pressure plate flipping function ensures that burrs on both sides can be completely removed, solving the problem of burr residue caused by unstable clamping and inconvenient flipping in traditional devices, and meeting the stringent requirements for processing precision of automotive air conditioning pressure plates.

[0032] Example 1:

[0033] like Figures 1 to 5 As shown in the figure, this embodiment provides a deburring device for processing automotive air conditioning pressure plates, including a base plate 1. The base plate 1 is rectangular, and the lower surface of a support frame 2 is bolted to the middle of the upper surface of the base plate 1. The two sides of the upper surface of the base plate 1 are connected to the two ends of a conveyor belt 6 through columns. The conveyor belt 6 is used for conveying the pressure plate. The upper end of the support frame 2 is bolted to the periphery of a cross slide assembly 3. A clamping mechanism 4 is provided inside the support frame 2. The clamping mechanism 4 is used for clamping the pressure plate. The lower surface of the clamping mechanism 4 is connected to the upper surface of a lifting assembly 5. The lifting assembly 5 is used for lifting the clamping mechanism 4. Positioning holes 10 are provided on the upper and lower periphery of the support frame 2. The positioning holes 10 are used for connecting other devices.

[0034] In this embodiment, the clamping mechanism 4 and the lifting assembly 5 constitute a deburring device for processing automotive air conditioning pressure plates according to this application.

[0035] It should also be noted that the automotive air conditioning pressure plate processing in this application can be for automotive air conditioning evaporator pressure plates, automotive air conditioning condenser pressure plates, automotive air conditioning fan assembly pressure plates, etc. Figure 1 In this embodiment, the processing of an automotive air conditioning pressure plate into an automotive air conditioning evaporator pressure plate is described as an example. Of course, other types of automotive air conditioning pressure plates can also be processed using a similar structure, which will not be elaborated on later.

[0036] Understandable, Figure 1 The deburring device is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, deburring devices can also include those that are more advanced than... Figure 1 More or fewer parts.

[0037] It should also be understood that the cross slide assembly 3 and the conveyor belt 6 were purchased from the market and are common knowledge in this field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] In addition, in this embodiment, the conveyor belt 6 drives the pressure plate to be processed to move below the clamping mechanism 4. The support frame 2 provides installation support for the cross slide group 3, the clamping mechanism 4 and the lifting assembly 5. The lifting assembly 5 drives the clamping mechanism 4 to rise and fall to adapt to the height of the pressure plate. The positioning hole 10 can be connected to external auxiliary devices through bolts to realize the basic functions of automatic conveying of the pressure plate, stable installation of core components and height adjustment, and to provide structural support for subsequent deburring operations.

[0039] Specifically, the lower surface of the cross slide assembly 3 is slidably connected to the upper end of the sliding block 8, the lower end of the sliding block 8 is internally connected to the upper end of the mounting head 9, and the lower end of the sliding block 8 is provided with a locking hole. The mounting head 9 is used for mounting the tool.

[0040] In this embodiment, the cross slide group 3 drives the sliding block 8 to move along the X-axis and Y-axis. The mounting head 9 is connected to the tool through a thread. The locking hole is inserted into the positioning pin to fix the relative position of the mounting head 9 and the sliding block 8, so as to realize the precise displacement and stable installation of the tool and ensure the accuracy of the deburring position.

[0041] Example 2:

[0042] A lifting component 5 is provided based on embodiment 1.

[0043] Specifically, the lifting assembly 5 includes a hydraulic rod 501. The lower fixed end of the hydraulic rod 501 is connected to the inner bottom surface of the support frame 2, and the telescopic end of the hydraulic rod 501 is connected to one side of the lower surface of the bearing plate 502. A guide rod 503 is provided on the other side of the bearing plate 502, and the upper and lower ends of the guide rod 503 are connected to one side of the support frame 2.

[0044] As a preferred implementation, the hydraulic rod 501 extends and retracts to drive the bearing plate 502 to rise and fall in the vertical direction, and the guide rod 503 restricts the horizontal displacement of the bearing plate 502 to ensure a smooth lifting process, thereby realizing the smooth lifting and lowering of the clamping mechanism 4, accurately adjusting the relative height between the pressure plate and the tool, and adapting to the processing needs of pressure plates of different thicknesses.

[0045] Example 3:

[0046] A clamping mechanism 4 is provided based on embodiment 2.

[0047] Specifically, the clamping mechanism 4 includes a placement box 401, one side of which is rotatably connected to one side of the clamping box 402. The placement box 401 is equipped with an electric telescopic rod 403 and a motor 409. The telescopic end of the electric telescopic rod 403 passes through the clamping box 402 and is rotatably connected to one side of the push block 404.

[0048] In this embodiment, the electric telescopic rod 403 drives the push block 404 to move horizontally inside the clamping box 402. The placement box 401 provides installation space for the electric telescopic rod 403 and the motor 409, realizing the relative rotation between the clamping box 402 and the placement box 401. The push block 404 avoids hard contact damage to the pressure plate and transmits power for subsequent clamping actions.

[0049] Specifically, the two ends of the push block 404 away from the electric telescopic rod 403 are rotatably connected to one end of the push rod 405, and the other end of the push rod 405 is rotatably connected to one end of the gear 406.

[0050] With this configuration, when the push block 404 moves, it drives the push rod 405 to rotate around the end of the gear 406, which in turn drives the gear 406 to rotate around its own center, thus converting the linear motion of the electric telescopic rod 403 into the rotational motion of the gear 406 and realizing the conversion of the power transmission direction.

[0051] Specifically, the side of the gear 406 away from the push rod 405 meshes with one end of the rack 407, and the other end of the rack 407 away from the gear 406 is connected to one end of the clamping rod 408. The clamping rod 408 slides in the middle of the side of the clamping box 402 away from the electric telescopic rod 403.

[0052] The clamping rod 408 has multiple anti-slip grooves on one side. The gear 406 rotates and drives the meshing rack 407 to move horizontally. The rack 407 simultaneously drives the clamping rod 408 to slide in the sliding hole, realizing the opening and closing of the clamping rod 408 and the synchronous action of the clamping rod 408. The anti-slip grooves increase the friction with the pressure plate, ensuring that the pressure plate clamps firmly and avoids surface damage.

[0053] Specifically, the output shaft of the motor 409 is connected to one end of the transmission shaft 410, and the other end of the transmission shaft 410 is connected to the drive wheel 411. The drive wheel 411 meshes with the driven wheel 412, and the driven wheel 412 is connected to the side of the clamping box 402 near the electric telescopic rod 403 by bolts.

[0054] In this embodiment, the output shaft of motor 409 rotates to drive transmission shaft 410 to rotate, transmission shaft 410 drives drive wheel 411 to rotate, drive wheel 411 meshes with and drives driven wheel 412 to rotate, driven wheel 412 drives clamping box 402 to rotate through bolts, so that clamping box 402 drives pressure plate to flip 180°, and the processing of both sides of pressure plate can be completed without manual intervention, improving the overall deburring.

[0055] In actual use, the pressure plate to be processed is first placed on one side of the conveyor belt 6. As the conveyor belt 6 starts, it moves the pressure plate. The electric telescopic rod 403 in the clamping mechanism 4 is activated. The telescopic end of the electric telescopic rod 403 extends and retracts, pushing the push block 404 to move along the inside of the clamping box 402. The movement of the push block 404 drives the push rod 405 to rotate. The push rod 405 drives the gear 406 to rotate around the center of the gear 406. The rotation of the gear 406 drives the meshing rack 407 to move. The movement of the rack 407 synchronously drives the clamping rod 408 to open. At this time, after the pressure plate moves to the position of the clamping mechanism 4, the telescopic end of the electric telescopic rod 403 drives the push block 404 to reset and the clamping rod 408 clamps both sides of the pressure plate. Then the conveyor belt 6 stops conveying and the hydraulic rod 501 is activated. The telescopic end of the hydraulic rod 501 pushes the bearing plate 502 to rise. The bearing plate 502 drives the clamping mechanism 4 to rise. At this time, the guide rod 50 on the side of the bearing plate 502 away from the hydraulic rod 501... 3. Guide and stabilize the plate while installing a scraper or chamfering tool at the lower end of the mounting head 9. After the clamping mechanism 4 moves the pressure plate to a suitable height, start the cross slide group 3. The cross slide group 3 moves the sliding block 8 and simultaneously moves the mounting head 9 and the tool. The mounting head 9 moves the tool to remove burrs. After the burrs on the pressure plate are removed, the hydraulic rod 501 lowers the clamping mechanism 4 by half its height and then starts the motor 409. The output shaft of the motor 409 drives the transmission shaft 410 to rotate. The rotation of the transmission shaft 410 drives the drive wheel 411 to rotate. Since the drive wheel 411 meshes with the driven wheel 412, the drive wheel 411 drives the driven wheel 412 to rotate. The rotation of the driven wheel 412 drives the clamping box 402 to rotate, thereby flipping the pressure plate. Then, start the hydraulic rod 501 to rise and process the other side of the pressure plate. After processing, the hydraulic rod 501 lowers the clamping mechanism 4, then release the clamping rod 408 and start the conveyor belt 6 to continue conveying.

[0056] The cross slide assembly 3, conveyor belt 6, electric telescopic rod 403, motor 409 and hydraulic rod 501 are all electrically connected to the PLC controller. The PLC controller is electrically connected to an external power supply. The PLC controller facilitates the power supply control of the electrical equipment, ensuring that the equipment can be powered on when needed, thus avoiding the situation where power cannot be supplied when needed.

[0057] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0058] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
