Description

Technical Field

[0001] This invention relates to the field of drilling technology, specifically to a drilling device and process for an automotive air conditioning reservoir housing. Background Technology

[0002] The automotive air conditioning receiver is a core auxiliary component of the air conditioning refrigeration system. Its main functions are to separate the refrigerant into gas and liquid phases, store liquid refrigerant, filter impurities, and absorb moisture to ensure stable system operation. After returning from the evaporator, the refrigerant is in a gas-liquid mixed state. The receiver separates the liquid refrigerant to prevent it from entering the compressor and causing "liquid slugging" damage. It also temporarily stores excess liquid refrigerant based on changes in air conditioning load, and then delivers it to the evaporator when needed to maintain stable cooling capacity. Furthermore, the automotive air conditioning receiver integrates a desiccant filter, which filters metal debris and impurities from the refrigerant to prevent clogging of pipes, and absorbs moisture in the system to prevent moisture from reacting with the refrigerant to form corrosive substances that could damage components.

[0003] The reservoir housing is a crucial component of the automotive air conditioning reservoir, serving a safety protection function. Drilling is required when machining the reservoir housing, necessitating the use of drilling equipment.

[0004] Currently, traditional drilling equipment is inconvenient to adjust the height of the drilling tool during use, making it less flexible in overall use. Furthermore, the debris generated during drilling is difficult to fall off and tends to accumulate on the surface of the reservoir shell and at the joint with the drilling tool, easily causing blockages. In severe cases, the drilling tool may even break. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: A drilling device for an automotive air conditioning receiver housing, comprising: The machine body, and a connecting plate that is slidably mounted on the top of the machine body, a guide rail is fixedly mounted on the side of the surface of the machine body, a driver is fixedly mounted on the surface of the connecting plate, and a movable feeding mechanism is mounted on the top of the connecting plate. A drilling mechanism includes a support frame and a lead screw. The support frame is fixedly installed on the side of the top of the machine body. The lead screw is rotatably installed in the middle of the support frame. A servo motor is fixedly installed on the top of the support frame. A connecting block is slidably installed inside the support frame. The connecting block and the lead screw are threaded together. A connecting arm is fixedly installed at the end of the connecting block away from the support frame. A drilling host is fixedly installed in the middle of the inner cavity of the connecting arm. A drill bit is detachably fixedly installed at the output end of the drilling host. A first wedge tooth is fixedly installed on the surface of the connecting arm near the drill bit. By rotating the output end of the servo motor, the lead screw can be driven to rotate. Combined with the threaded connection between the connecting block and the lead screw, and under the support and guidance of the support frame, the connecting block is driven to move downward, which allows the connecting arm to move together with the connecting block. This allows for adjustment of the position of the drilling host and the drill bit, and adjustment of the height of the drill bit.

[0006] Preferably, the output end of the driver is engaged with the surface of the guide rail, and the top end of the lead screw is fixedly installed with the output end of the servo motor via a coupling.

[0007] Preferably, the connecting arm is installed horizontally, and there are two first wedge teeth, which are installed symmetrically along the drill bit.

[0008] Preferably, the mobile feeding mechanism includes a frame, a rotator is fixedly installed at the middle of the top of the frame, a worktable is fixedly installed at the rotating end of the top of the rotator, a limit slot is opened on the side of the top of the worktable, a round hole is opened on the surface of the worktable near the limit slot, and a clamping assembly is installed at the middle of the top of the worktable. The drill bit is horizontally installed and perpendicular to the end face of the liquid reservoir housing in the limit slot. When the drill bit rotates to drill, the debris generated by drilling will fall off due to its own gravity and will not accumulate at the joint position between the drill bit and the end face of the liquid reservoir housing, thus preventing debris blockage.

[0009] Preferably, the worktable is hexagonal, and there are six limiting slots, which are evenly distributed on the sides of the top of the worktable.

[0010] By embedding the outer circular surface of the automotive air conditioning receiver housing blank into the interior of the limiting slot, the automotive air conditioning receiver housing blank can be initially positioned. Then, by rotating the worktable, multiple sets of limiting slots are placed on the receiver housing, which facilitates orderly feeding of each one.

[0011] Preferably, the clamping assembly includes a circular base and a U-shaped connecting rod. The circular base is fixedly installed to the middle of the top of the worktable by screws. The U-shaped connecting rod is slidably installed between the worktable and a circular hole. A clamping shell is fixedly installed on the top of the inner side of the U-shaped connecting rod. A reset elastic strip is fixedly connected between the arc-shaped surface of the outer side of the clamping shell and the edge of the top of the circular base. The bottom end of the U-shaped connecting rod is pressed by the inclined surface at the bottom edge of the first wedge tooth, causing the U-shaped connecting rod to drive the clamping shell to move downward. The reset elastic strip is compressed and deformed elastically, and is clamped to the top of the reservoir shell blank by the clamping shell, thus pressing and fixing the reservoir shell blank, so that the reservoir shell blank will not loosen. As the reservoir shell blank moves closer to the drill bit, the reservoir shell blank can be drilled.

[0012] Preferably, the bottom end of the zigzag connecting rod extends to the bottom of the worktable, the clamping shell is installed directly above the limiting slot, and the reset elastic strip is installed at an angle.

[0013] The rotating end at the top of the rotator drives the worktable to rotate, causing the drilled reservoir shell to be removed. The adjacent reservoir shell blank is then rotated to the side closer to the drill bit, thus completing the discharge. The rotator and worktable can then be moved closer to the grinding disc by rotating the output end of the driver, so that the hole opening can be ground and deburred.

[0014] Preferably, a grinding mechanism is installed at the top of the machine body and at the end away from the connecting arm. The grinding mechanism includes a support base, the bottom of which is fixedly installed to the top of the machine body. A power source is fixedly installed at the middle of the surface of the support base, and a grinding disc is fixedly installed at the output end of the power source. A second wedge-shaped tooth is fixedly installed on the surface of the support base and near the grinding disc. A vacuum cleaner is fixedly installed at the bottom of the surface of the support base. The output end of the power source drives the grinding disc to rotate, which can grind the burrs on the opening of the liquid reservoir housing. The air inlet of the vacuum cleaner draws in air, and the airflow carries the dust into the interior of the vacuum cleaner for dust removal.

[0015] Preferably, there are two second wedge-shaped teeth, and the two second wedge-shaped teeth are symmetrically installed along the grinding disc, and the air intake of the vacuum cleaner is installed directly below the grinding disc.

[0016] A drilling process for an automotive air conditioning receiver housing includes the following steps: Step 1: Cleaning treatment. Wipe the surface of the car air conditioning receiver housing blank with a cleaning agent to remove oil and oxide layer; Step 2: Preparation work, place the automotive air conditioning receiver housing blank in the designated position, and limit and fix the automotive air conditioning receiver housing; Step 3: Drilling operation. Select a high-speed steel drill bit and adjust the machine speed to drill holes in the automotive air conditioning receiver housing blank. Step 4: Deburring. Use high-speed rotation to grind and remove the burrs generated at the orifice. Step 5: Unloading and Removing Parts. Loosen the car air conditioning reservoir housing after drilling and grinding, and remove the parts. Step Six: Inspection and Acceptance. Use calipers and micrometers to measure the hole diameter and position to ensure accuracy.

[0017] This invention provides a drilling device and process for the housing of an automotive air conditioning receiver. It has the following beneficial effects: I. The drilling equipment and process for the housing of the automotive air conditioning receiver utilizes the rotation of the output end of the servo motor to drive the lead screw to rotate. The connecting block is connected to the lead screw by a threaded installation, and under the support and guidance of the support frame, the connecting block is driven to move downwards. This allows the connecting arm to move together with the connecting block, thereby adjusting the position of the drilling host and the drill bit, and adjusting the height of the drill bit.

[0018] 2. The drilling equipment and process for the automotive air conditioning reservoir housing utilizes a horizontally installed drill bit, with the drill bit perpendicular to the end face of the reservoir housing within the limiting slot. When the drill bit rotates to drill, the debris generated during drilling will fall off due to its own gravity and will not accumulate at the junction of the drill bit and the end face of the reservoir housing, thus reducing the likelihood of debris blockage.

[0019] III. The drilling equipment and process for the automotive air conditioning receiver housing: The automotive air conditioning receiver housing blank is placed on the limiting slot at the top of the worktable. By embedding the outer circular surface of the automotive air conditioning receiver housing blank into the inside of the limiting slot, the automotive air conditioning receiver housing blank can be initially positioned. The worktable is rotated by the rotating device to place the receiver housing in multiple sets of limiting slots, which facilitates the orderly feeding of the blanks one by one.

[0020] IV. The drilling equipment and process for the automotive air conditioning reservoir housing involves pressing the bottom end of the U-shaped connecting rod with the inclined surface at the bottom side of the first wedge tooth. This causes the U-shaped connecting rod to move the clamping shell downwards, compressing the reset elastic strip and causing it to deform elastically. The clamping shell then presses the top of the reservoir housing blank, thus fixing the reservoir housing blank in place and preventing it from becoming loose. As the reservoir housing blank moves closer to the drill bit, drilling can then be performed on the reservoir housing blank.

[0021] V. The drilling equipment and process for the automotive air conditioning reservoir housing involves rotating the worktable via the rotating end at the top of the rotator, which moves the drilled reservoir housing out and rotates the adjacent reservoir housing blank to the side closer to the drill bit for material discharge. Then, by rotating the output end of the driver again, the rotator and worktable can be moved to the side closer to the grinding disc for grinding and deburring the hole opening.

[0022] VI. The drilling equipment and process for the automotive air conditioning reservoir housing involves pressing the bottom end of the zig-shaped connecting rod with the inclined surface at the bottom side of the second wedge tooth. The zig-shaped connecting rod drives the clamping shell to move downward, thus fixing the reservoir housing again. The output end of the power source drives the grinding disc to rotate, which can grind the burrs at the opening of the reservoir housing. The air inlet of the vacuum cleaner draws in air, and the airflow carries the dust into the interior of the vacuum cleaner, thus treating the dust. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] For the first embodiment, please refer to... Figure 1-5 The present invention provides a technical solution: A drilling device for an automotive air conditioning receiver housing, comprising: The machine body 1, and the connecting plate 2 which is slidably installed on the top of the machine body 1, the guide rail 3 which is fixedly installed on the side of the surface of the machine body 1, the driver 4 which is fixedly installed on the surface of the connecting plate 2, and the mobile feeding mechanism 5 which is installed on the top of the connecting plate 2. The drilling mechanism 6 includes a support frame 61 and a lead screw 62. The support frame 61 is fixedly installed on the side of the top of the machine body 1. The lead screw 62 is rotatably installed in the middle of the inside of the support frame 61. A servo motor 63 is fixedly installed on the top of the support frame 61. A connecting block 64 is slidably installed inside the support frame 61. The connecting block 64 is threadedly installed with the lead screw 62. A connecting arm 65 is fixedly installed at the end of the connecting block 64 away from the support frame 61. A drilling host 66 is fixedly installed in the middle of the inner cavity of the connecting arm 65. The output end of the drilling host 66 is detachably fixed. The drill bit 67 is mounted on the surface of the connecting arm 65, and a first wedge tooth 68 is fixedly installed near the drill bit 67. When the servo motor 63 is turned on, the rotation of the output end of the servo motor 63 can drive the lead screw 62 to rotate. The connecting block 64 is connected to the lead screw 62 by a thread, and under the support and guidance of the support frame 61, the connecting block 64 is driven to move downward, so that the connecting arm 65 can be moved together with the connecting block 64. This allows the position of the drilling host 66 and the drill bit 67 to be adjusted, and the height of the drill bit 67 to be adjusted.

[0027] The output end of the driver 4 is engaged with the surface of the guide rail 3, and the top end of the lead screw 62 is fixedly installed with the output end of the servo motor 63 via a coupling.

[0028] The connecting arm 65 is installed horizontally, and there are two first wedge teeth 68, which are installed symmetrically along the drill bit 67.

[0029] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The mobile feeding mechanism 5 includes a frame 51. A rotator 52 is fixedly installed at the middle of the top of the frame 51. A worktable 53 is fixedly installed at the rotating end of the top of the rotator 52. A limit slot 54 is opened on the side of the top of the worktable 53. A round hole 55 is opened on the surface of the worktable 53 near the limit slot 54. A clamping assembly 56 is installed at the middle of the top of the worktable 53. A drill bit 67 is horizontally installed and perpendicular to the end face of the liquid reservoir housing in the limit slot 54. When the drill bit 67 rotates to drill, the debris generated by drilling will fall with its own gravity and will not accumulate at the joint position between the drill bit 67 and the end face of the liquid reservoir housing, so that debris blockage is not likely to occur.

[0030] The worktable 53 is hexagonal, with six limiting slots 54 evenly distributed on the top side of the worktable 53. The cleaned automotive air conditioning receiver housing blank is placed in the limiting slot 54 on the top of the worktable 53. The outer circular surface of the automotive air conditioning receiver housing blank is embedded into the inside of the limiting slot 54, which can initially position the automotive air conditioning receiver housing blank. The worktable 53 is rotated by the rotator 52 to place the receiver housing in multiple limiting slots 54, which facilitates the orderly loading of materials one by one.

[0031] The clamping assembly 56 includes a circular base 561 and a U-shaped connecting rod 562. The circular base 561 is fixedly installed to the middle of the top of the worktable 53 by screws. The U-shaped connecting rod 562 is slidably installed between the worktable 53 and the circular base 562 through a circular hole 55. A clamping shell 563 is fixedly installed on the top of the inner side of the U-shaped connecting rod 562. A reset elastic strip 564 is fixedly connected between the arc-shaped surface of the outer side of the clamping shell 563 and the side of the top of the circular base 561. When the limiting groove 54 for the automotive air conditioning reservoir housing blank is rotated to the front of the drill bit 67, the driver 4 can be activated to start working. The rotation of the output end of the driver 4 and the connection between the output end of the driver 4 and the worktable 562 are used to activate the driver 4. The guide rails 3 are meshed together and, with the sliding connection of the connecting buckle plate 2, the rotator 52 and the worktable 53 move together toward the side closer to the drill bit 67. The inclined surface at the bottom edge of the first wedge tooth 68 presses the bottom end of the zig-shaped connecting rod 562, causing the zig-shaped connecting rod 562 to drive the clamping shell 563 to move downward. The reset elastic strip 564 is compressed and deformed elastically, and is clamped to the top of the reservoir shell blank by the clamping shell 563, thus pressing and fixing the reservoir shell blank, so that the reservoir shell blank will not loosen. As the reservoir shell blank moves closer to the drill bit 67, the reservoir shell blank is drilled.

[0032] The bottom end of the Z-shaped connecting rod 562 extends to the bottom of the worktable 53. The clamping shell 563 is installed directly above the limiting slot 54. The reset elastic strip 564 is installed at an angle. When the drilling of the reservoir shell blank is completed, it can be rotated in the opposite direction through the output end of the driver 4, so that the reservoir shell is away from the drill bit 67. When the rotator 52 and the worktable 53 move to the middle of the machine body 1, the movement can be paused, and the worktable 53 can be rotated again through the rotating end at the top of the rotator 52, so that the drilled reservoir shell is moved out, and the adjacent reservoir shell blank is rotated to the side closer to the drill bit 67, so that the material can be discharged. And through the rotation of the output end of the driver 4, the rotator 52 and the worktable 53 can be moved to the side closer to the grinding disc 73, so as to grind and deburr the hole opening.

[0033] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 9 As shown: A drilling process for an automotive air conditioning receiver housing includes the following steps: Step 1: Cleaning treatment. Wipe the surface of the car air conditioning receiver housing blank with a cleaning agent to remove oil and oxide layer; Step 2: Preparation work, place the automotive air conditioning receiver housing blank in the designated position, and limit and fix the automotive air conditioning receiver housing; Step 3: Drilling operation. Select a high-speed steel drill bit and adjust the machine speed to drill holes in the automotive air conditioning receiver housing blank. Step 4: Deburring. Use high-speed rotation to grind and remove the burrs generated at the orifice. Step 5: Unloading and Removing Parts. Loosen the car air conditioning reservoir housing after drilling and grinding, and remove the parts. Step Six: Inspection and Acceptance. Use calipers and micrometers to measure the hole diameter and position to ensure accuracy.

[0034] A grinding mechanism 7 is installed at the top of the machine body 1, away from the connecting arm 65. The grinding mechanism 7 includes a support base 71, the bottom of which is fixedly installed to the top of the machine body 1. A power source 72 is fixedly installed at the middle of the surface of the support base 71, and a grinding disc 73 is fixedly installed at the output end of the power source 72. A second wedge-shaped tooth 74 is fixedly installed on the surface of the support base 71 near the grinding disc 73. A vacuum cleaner 75 is fixedly installed at the bottom of the surface of the support base 71. As the rotator 52 and the worktable 53 move toward the side closer to the grinding disc 73, the second wedge-shaped tooth 74 is used to insert... Once inserted above the bottom end of the Z-shaped connecting rod 562, the bottom end of the Z-shaped connecting rod 562 can be pressed by the inclined surface on the bottom side of the second wedge-shaped tooth 74. The Z-shaped connecting rod 562 drives the clamping shell 563 to move downward, fixing the liquid reservoir housing again. At this time, the power source 72 and the vacuum cleaner 75 are turned on to work. The output end of the power source 72 drives the grinding disc 73 to rotate, which can grind the burrs on the opening of the liquid reservoir housing. The air inlet of the vacuum cleaner 75 draws in air, and the airflow carries the dust into the interior of the vacuum cleaner 75 for dust treatment.

[0035] There are two second wedge teeth 74, and the two second wedge teeth 74 are symmetrically installed along the grinding disc 73. The air intake of the vacuum cleaner 75 is installed directly below the grinding disc 73.

[0036] In use, the operator first turns on the servo motor 63. The rotation of the output end of the servo motor 63 can drive the lead screw 62 to rotate. The connecting block 64 is connected to the lead screw 62 by a thread. Under the support and guidance of the support frame 61, the connecting block 64 is driven to move downward, which can cause the connecting arm 65 to move together with the connecting block 64. This allows the position of the drilling host 66 and the drill bit 67 to be adjusted, and the height of the drill bit 67 to be adjusted. At this time, the worker places the cleaned automotive air conditioning receiver housing blank into the limiting slot 54 position on the top of the workbench 53. By embedding the outer circular surface of the automotive air conditioning receiver housing blank into the limiting slot 54, the automotive air conditioning receiver housing blank can be initially positioned. The workbench 53 is then rotated by the rotator 52 to place the receiver housings into multiple limiting slots 54, which facilitates orderly loading of the blanks one by one. When the limiting slot 54 of the automotive air conditioning reservoir housing blank is rotated to the front of the drill bit 67, the driver 4 can be turned on to start working. By rotating the output end of the driver 4 and engaging with the guide rail 3, and with the sliding connection of the connecting plate 2, the rotator 52 and the worktable 53 move together toward the side closer to the drill bit 67. The inclined surface at the bottom side of the first wedge tooth 68 presses the bottom end of the Z-shaped connecting rod 562, causing the Z-shaped connecting rod 562 to drive the clamping shell 563 to move downward. The reset elastic strip 564 is compressed and deformed elastically, and is clamped to the top of the reservoir housing blank by the clamping shell 563, thus pressing and fixing the reservoir housing blank so that the reservoir housing blank will not loosen. As the reservoir housing blank moves closer to the drill bit 67, the reservoir housing blank is drilled. Furthermore, the drill bit 67 is installed horizontally, and the drill bit 67 is perpendicular to the end face of the liquid reservoir housing in the limiting slot 54. When the drill bit 67 rotates to drill, the debris generated by the drilling will fall down due to its own gravity and will not accumulate at the joint position between the drill bit 67 and the end face of the liquid reservoir housing, so that debris blockage is not likely to occur. Once the drilling of the reservoir housing blank is completed, the output end of the driver 4 can be rotated in the opposite direction to move the reservoir housing away from the drill bit 67. When the rotator 52 and the worktable 53 are moved to the middle of the machine body 1, the movement can be paused, and the worktable 53 can be rotated again by the rotating end at the top of the rotator 52 to move the drilled reservoir housing out, and rotate the adjacent reservoir housing blank to the side closer to the drill bit 67 to complete the discharge. Then, by rotating the output end of the driver 4 again, the rotator 52 and the worktable 53 can be moved to the side closer to the grinding disc 73. Furthermore, as the rotator 52 and the worktable 53 move towards the side closer to the grinding disc 73, the second wedge tooth 74 is inserted above the bottom end of the zig-shaped connecting rod 562. The inclined surface at the bottom side of the second wedge tooth 74 can press the bottom end of the zig-shaped connecting rod 562. The zig-shaped connecting rod 562 drives the clamping shell 563 to move downward, fixing the liquid reservoir housing again. At this time, the power source 72 and the vacuum cleaner 75 are turned on to work. The output end of the power source 72 drives the grinding disc 73 to rotate, which can grind the burrs on the opening of the liquid reservoir housing. The air inlet of the vacuum cleaner 75 sucks in air, and the airflow carries the dust into the interior of the vacuum cleaner 75 for dust treatment. Once the drilling and grinding of the automotive air conditioning reservoir housing is complete, the output of the driver 4 can be rotated again to move the rotator 52 and the worktable 53 away from the grinding disc 73. The rotator 52 and the worktable 53 are then moved back to the center, the pressure on the Z-shaped connecting rod 562 disappears, and under the elastic support of the reset elastic strip 564, the clamping shell 563 moves upward, releasing the automotive air conditioning reservoir housing. The housing is then removed by the outsourced robotic arm, and the rotator 52 drives the worktable 53 to rotate. This cycle is repeated to enable batch processing.
