[0002] The air compressor housing is a component used to protect the internal core components, such as the compressor main unit, motor, and oil-gas separator. During use, the air compressor housing needs to be drilled to allow cables and pipes to pass through and be sealed. However, most existing housings rely on manual drilling. The hole position and diameter of the air compressor housing have high precision requirements. When manually marking and positioning, the hole position is prone to deviation, resulting in poor processing consistency and easy confusion in subsequent assembly processes. Utility Model Content

One set of shafts is connected to a drive motor via a coupling. Through the cooperation between the drive motor and the shafts, the storage seat can rotate in a circular motion. The guide rail and the support base work together to allow the storage base to move relative to each other along the length of the guide rail. A slot is provided on one side of the storage seat, and a blocking component is movably installed on the slot. The blocking component includes a support plate, which is movably disposed on the slot. A limit plate is vertically disposed on the support plate, and the limit plate is located above the storage seat. A limiting area for the workpiece is formed between the storage seats.

The first push rod component is provided in two sets and is movably mounted on the two sets of connecting parts respectively. A support rod component is connected to the piston end of the first push rod component. A pad is installed on the end of the support rod component away from the first push rod component. A clamping area for the workpiece is formed between the two sets of clamping components. The clamping area can be expanded or reduced by extending or retracting the piston end in the first push rod component.

[0006] In one embodiment, a rotary drive component is installed at the bottom of the storage base. The rotary drive component has a rotating part, a portion of which extends onto the storage base and is fitted with a storage tray. When the workpiece is placed on the tray, it rotates in a circular motion through the cooperation of the rotation drive component.

[0007] In one embodiment, slots are provided on both sides of the platform, the slots are located on one side of the bearing seat, and a second push rod component is provided on the outer side of the platform. The piston end of the second push rod component is equipped with a receiving block, and a connecting rod is provided on the receiving block. One end of the connecting rod passes through the slot and connects to the bearing seat. The bearing seat moves relative to the piston end in the second push rod assembly by extending and retracting.

[0008] In one embodiment, the limiting plate is provided with several spaced grooves, and an elastic element is provided in the groove. One end of the elastic element is connected to the inner wall of the groove, and the other end is connected to a contact pad. When the workpiece is placed on the base, the contact pad abuts against the workpiece in cooperation with the elastic element.

[0009] In one embodiment, the support plate is provided with threaded holes, and the threaded holes are provided in a plurality of them and are spaced apart along the length direction of the support plate; The storage base is provided with mounting holes extending into the slot. By moving the support plate within the slot, the mounting holes are aligned with one of the sets of threaded holes. When the mounting hole and one of the threaded holes are aligned and a bolt is threadedly connected, the support plate is fixed to the stand.

[0010] In one embodiment, the support rod component includes a fixed rod and a movable rod. The fixed rod is connected to the piston end of the first push rod component. The fixed rod has a groove, a portion of the movable rod is located in the groove, and a pad is disposed at the end of the movable rod away from the fixed rod. The pad moves closer to or away from the fixed rod by moving the movable rod within the groove.

[0011] In one embodiment, a controller is also included, which is connected to the drilling machine, the drive motor, the first push rod assembly, and the second push rod assembly.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a drilling device for processing air compressor housings. A workpiece placement seat is connected to a support seat via a connecting part connected to a shaft. Since the support seat is movably mounted on a guide rail within the base, the movement of the support seat can move the workpiece below the central bore shaft of the drilling machine for drilling. The movement of the support seat on the guide rail allows different positions of the workpiece to be positioned below the bore shaft for drilling operations at different locations. Furthermore, since one set of shafts is connected to a drive motor, the drive motor rotates the shafts, causing the placement seat to synchronously rotate with the workpiece, enabling drilling operations on the side of the workpiece. Simultaneously, the placement seat is equipped with blocking components. The support plate and limit plate in the blocking components can block the workpiece at different positions, ensuring the workpiece remains stable during rotation. This solves the problem of poor drilling accuracy and inconsistent processing caused by manual drilling in existing housings. Attached Figure Description

[0020] Reference Figures 1-5A drilling device for machining an air compressor housing includes a base 1, a drilling machine 11 mounted on one side of the base 1, and a cavity 12 located on one side of the drilling machine 11. Two sets of spaced-apart guide rails 121 are arranged within the cavity 12. These two sets of spaced-apart guide rails 121 provide double-rail guidance for a support seat 2. When the support seat 2 moves along the guide rails 121, the double rails limit its lateral displacement, avoiding the swaying that easily occurs with traditional single-rail guidance. The platform 11 is equipped with a support seat 2, a receiving plate 21 on the support seat 2, a bearing seat 22 on the receiving plate 21, and a shaft 23 on the bearing seat 22. The structure of the bearing seat 22 and the shaft 23 provides low-friction rotational support for the storage seat 3. Part of the shaft 23 is located outside the bearing seat 22 and is equipped with a connecting part 231. The storage seat 3 is connected between the two sets of connecting parts 231. The drilling machine 11 has a drill shaft, which is located above the storage seat 3. The platform 1 integrates the drilling machine 11 and the support structure into the same base. On the one hand, it avoids the shaking of the equipment caused by the traditional scattered layout. On the other hand, the cavity 12 provides a closed protective space for the movement of the support seat 2, preventing metal chips from splashing to the outside during the processing and protecting the safety of the operators. One set of shafts 23 is connected to a drive motor 232 via a coupling. The drive motor 232 is a servo drive motor in the prior art. Through the cooperation of the drive motor 232 and the shaft 23, the storage seat 3 can rotate in a circle. The drive motor 232 provides power for the rotation of the shaft 23, and the drive motor 232 can precisely control the rotation angle through a program, eliminating the need for manual rotation of the storage seat to adjust the angle, thereby expanding the processing range of the device and adapting to the needs of special structure air compressor housings. Through the cooperation of the guide rail 121 and the bearing seat 2, the storage seat 3 can move relative to the guide rail 121 along its length. The length of the air compressor housing varies significantly for different models. By the linear movement of the bearing seat 2 along the guide rail 121, the lateral position of the storage seat 3 can be directly adjusted, improving the overall adaptability of the device. A slot 31 is provided on one side of the storage seat 3. A blocking component 4 is movably installed on the slot 31. The blocking component 4 includes a support plate 41, which is movably disposed on the slot 31. A limiting plate 42 is vertically disposed on the support plate 41. The limiting plate 42 is located above the storage seat 3. A limiting area for the workpiece is formed between the storage seat 3 and the storage seat 3. By moving the support plate 41 in the slot 31, the limiting area can be expanded or reduced. The slot 31 forms a lateral limiting on the support plate 41, preventing the support plate 41 from shifting due to workpiece compression. This ensures that the limiting plate 42 always remains perpendicular to the workpiece and will not tilt due to rotation. The bottom of the platform 1 is provided with support legs 15. Several support legs 15 are evenly distributed around the platform 1. The support legs 15 support the platform 1 as a whole through multi-point support, evenly distributing the weight of the device. At the same time, the platform can be kept level by adjusting the height of the support legs 15. If the ground is uneven, the platform can be kept level by adjusting the height of a single support leg 15, thereby ensuring the overall stability of the device and avoiding accuracy deviations and equipment damage caused by drilling vibration.

[0021] Based on the above structure, by placing the workpiece to be processed on the mounting base 3, and since the mounting base 3 is connected to the shaft 23 mounted on the bearing seat 22 via the connecting part 231, and the bearing seat 22 is located on the receiving plate 21 connected to the bearing seat 2, the workpiece can be moved to below the drill spindle in the drilling machine 11 by the movement of the bearing seat 2 along the guide rail 121 for drilling operation. Furthermore, according to actual processing needs, one set of shafts 23 can be rotated by the drive motor 232, thereby causing the mounting base 3 to drive the shafts 23 to rotate synchronously. And by moving the bearing seat 2, the workpiece is always kept below the drill spindle. A blocking component 4 is movably installed on one side of the storage seat 3 via a slot 31. The support plate 41 in the blocking component 4 can support the bottom of the workpiece when it rotates, and the limiting plate 42 connected to the support plate 41 can clamp the side of the workpiece, thereby ensuring the stability of the workpiece when it rotates. Through the cooperation of the bearing seat 2 and the guide rail 121, the workpiece can be moved, so that different horizontal positions of the workpiece are located below the drilling machine 11. At the same time, the drive motor 232 drives the shaft 23 to make the storage seat 3 rotate synchronously, thereby enabling drilling operations at different angles of the workpiece, reducing manual intervention and improving the accuracy of processing.

[0022] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 It also includes a clamping component 5, which includes a first push rod component 51. The first push rod component 51 can be a pneumatic push rod, hydraulic push rod or electric push rod in the prior art. The first push rod component 51 is provided in two sets and is movably installed on the two sets of connecting parts 231 respectively. A support rod component 52 is connected to the piston end of the first push rod component 51. A pad 53 is installed at the end of the support rod component 52 away from the first push rod component 51. The pad 53 is made of rubber. A clamping area for the workpiece is formed between the two sets of clamping components 5. The clamping area can be expanded or reduced by extending and retracting the piston end in the first push rod component 51. When the piston end extends, the two sets of pads 53 move closer to each other, the clamping area shrinks, and the workpiece is clamped. When the piston end retracts, the clamping area expands and the workpiece is released. Through two sets of symmetrical clamping, a uniform clamping force is applied from both sides to ensure that the workpiece has no displacement throughout the drilling process. At the same time, the clamping area can be adjusted with the extension and retraction of the push rod to adapt to air compressor housings of different widths. Furthermore, the position of the workpiece can be adjusted by extending and retracting the piston through a single first push rod component 51.

[0023] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The bottom of the storage base 3 is equipped with a rotary drive component 6. The rotary drive component 6 adopts an electric turntable driven by a motor, which is a technology in the prior art. The rotary drive component 6 has a rotating part, which extends to the storage base 3 and is equipped with a storage tray 61. When the workpiece is located on the storage tray 61, the workpiece is rotated in a circle by the cooperation of the rotary drive component 6. By rotating the workpiece, multi-angle drilling of the workpiece can be achieved, reducing the position adjustment of the drilling machine and improving processing efficiency and accuracy. Air compressor housings often need to be drilled with circumferentially distributed holes on the side and top. The traditional method requires multiple movements of the drilling machine or repositioning of the workpiece, which is easy to accumulate errors. This structure can complete the processing of holes at different angles in the same station by rotating the workpiece, which is suitable for different hole processing needs.

[0024] In one embodiment, reference is made to Figures 1-3 The platform 1 is also provided with slots 13 on both sides, the slots 13 are located on one side of the bearing seat 2, and the platform 1 is also provided with a second push rod component 14 on the outer side. The second push rod component 14 can be a pneumatic push rod, hydraulic push rod or electric push rod in the prior art. The piston end of the second push rod component 14 is equipped with a receiving block 141, and a connecting rod 1411 is provided on the receiving block 141. One end of the connecting rod 1411 passes through the slot 13 and connects to the bearing seat 2. By extending and retracting the piston end in the second push rod component 14, the bearing seat 2 can be moved relative to the piston. Through the second push rod component 14, the bearing seat 2 is driven to translate by the push rod, which can accurately adjust the relative position of the drilling assembly and the workpiece. Different specifications of boxes can be processed without changing the tooling. This allows the workpiece to be in a suitable position when it is flipped. At the same time, the translation accuracy driven by the push rod is high, avoiding the error of manual adjustment and improving the stability of translation.

[0025] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 5The limiting plate 42 is provided with several spaced grooves 421. An elastic element 422 is provided in the groove 421. One end of the elastic element 422 is connected to the inner wall of the groove 421, and the other end is connected to a contact pad 423. The contact pad 423 is made of rubber. The arrangement of several elastic elements 422 can disperse the pressure borne by the contact pad 423 when it contacts the workpiece. The elastic element 422 adopts the pressure spring or extension spring in the prior art. When the workpiece is placed on the base 3, the contact pad 423 abuts against the workpiece in cooperation with the elastic element 422. Under the elastic force of the elastic element 422, the contact pad 423 tightly adheres to the surface of the workpiece, forming a flexible limit. The elastic force of the elastic element 422 can press the workpiece against the preset positioning surface, fill the small gap between the workpiece and the positioning surface, and prevent the workpiece from moving slightly during drilling. The elastic element 422 can expand and contract with slight differences in the size of the workpiece, adapt to the limit requirements of non-standard boxes, and achieve an adaptive effect.

[0026] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 6 The support plate 41 is provided with threaded holes 411. Several threaded holes 411 are provided and are distributed at intervals along the length direction of the support plate 41, so that the support plate 41 can be fixed in multiple preset positions. The storage base 3 is provided with mounting holes extending into the slot 31. By moving the support plate 41 within the slot 31, the mounting holes are aligned with one set of threaded holes 411. When the mounting holes and one set of threaded holes 411 are aligned and threaded with bolts, the support plate 41 is fixed to the storage base 3. Moving the support plate 41 along the slot 31 aligns the mounting holes of the storage base 3 with the target threaded holes 411. The bolts are then screwed in to fix the support plate, achieving multi-position locking of the support plate 41. This adapts to the positioning requirements of boxes of different lengths, meeting the end positioning or intermediate limiting requirements of boxes of different lengths. At the same time, the threaded connection has high fixing strength, and the support plate 41 will not shift during drilling, ensuring positioning accuracy.

[0027] In one embodiment, reference is made to Figures 1-3The support rod component 52 includes a fixed rod 521 and a movable rod 522. The fixed rod 521 is connected to the piston end of the first push rod component 51. The fixed rod 521 has a groove, and part of the movable rod 522 is located in the groove. The pad 53 is located at the end of the movable rod 522 away from the fixed rod 521. By moving the movable rod 522 in the groove, the pad 53 can move closer to or further away from the fixed rod 521. By fine-tuning the position of the pad 53, the fit between the pad 53 and the workpiece can be precisely adjusted to meet the clamping requirements of irregular surface boxes. With only the coarse adjustment of the first push rod component 51, the pad 53 may not be able to fully fit the workpiece surface, resulting in uneven clamping force. This ensures that the clamping force is transmitted evenly. At the same time, the fine-tuning function can compensate for machining errors and improve clamping accuracy.

[0028] In one embodiment, reference is made to Figures 1-3 It also includes a controller 7, which adopts a programmable controller in the prior art. The controller 7 is connected to the drilling machine 11, the drive motor 232, the first push rod component 51 and the second push rod component 14. The controller 7 presets the processing program and automatically controls the coordinated action of each component. For example, the first push rod component 51 automatically clamps the workpiece, the second push rod component 14 automatically adjusts the position of the bearing seat, the drive motor 232 drives the drilling machine 11 to start, and the rotation drive component 6 automatically adjusts the workpiece angle. No manual operation is required throughout the process, realizing full automation of the drilling process, improving processing efficiency and consistency, and reducing human error.
