DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0026] like Figures 1 to 5As shown, the compressor housing blade deburring mechanism described in this embodiment includes a burr removal component 100 and a housing conveying mechanism 200. The mechanism is mainly used to efficiently remove burrs from the blade of the compressor housing to improve the quality and performance of the compressor.

[0027] Specifically, the burr removal components 100 are arranged in plurality along the first direction at intervals, and each burr removal component 100 includes a turntable 10, a drive motor and a gauze wheel 11 arranged on the table surface of the turntable 10; the gauze wheel 11 is coaxially fixedly installed on the drive shaft of the drive motor, and is configured to rotate synchronously with the drive motor under the drive of the turntable 10; the shell conveying mechanism 200 is used to convey the compressor shell along the first direction, so that the blade part of the compressor shell contacts the gauze of multiple gauze wheels 11 in sequence during the conveying process.

[0028] In this way, Figure 1 and Figure 2 As shown, multiple burr removal assemblies 100 are linearly arranged along a first direction. This multi-station design can simultaneously remove burrs from the passing compressor casing, significantly improving the processing efficiency. The structure of each burr removal assembly 100 is basically the same, that is, the turntable 10 serves as the basic support structure of the burr removal assembly 100, and the drive motor is fixed on its table to provide power for the rotation of the gauze wheel 11. The gauze wheel 11 is a component that directly contacts the blade of the compressor casing for burr removal. It is connected to the drive shaft of the drive motor through a coaxial fixed installation to ensure the stability and reliability of power transmission.

[0029] During operation, the turntable 10 can drive the entire drive motor and the gauze wheel 11 to rotate horizontally synchronously. This rotation method can make the gauze wheel 11 more fully contact the blade of the compressor housing, improve the burr removal effect, and enable the gauze material of the gauze wheel 11 to effectively grind off the burrs on the blade while avoiding excessive damage to the housing; and the housing conveying mechanism 200 is responsible for conveying the compressor housing to be deburred to the working area of ​​each burr removal component 100 according to a predetermined trajectory and speed, that is, when the compressor housing moves in the first direction driven by the housing conveying mechanism 200, its blade will contact the gauze surface of multiple rotating gauze wheels 11 in turn, thereby realizing a continuous burr removal process. This continuous processing method further improves the overall production efficiency. The specific structure of the housing conveying mechanism 200 will be introduced in detail later.

[0030] Through the above design, the compressor casing blade deburring mechanism achieves efficient and reliable burr removal, which can effectively improve the quality and performance of compressor products, increase production efficiency and reduce production costs.

[0031] In some embodiments, as Figure 2 As shown, the shell conveying mechanism 200 includes a conveyor belt 20 arranged along a first direction, a shell positioning unit 30, and a linear drive device 40 for driving the shell positioning unit 30 to move in the first direction. The shell positioning unit 30 is configured to grasp and move the compressor shells located on the conveyor belt 20 under the drive of the linear drive device 40. Specifically, the conveyor belt 20 serves as the basic conveying mechanism. Its endless belt rotates in the first direction driven by the drive device, continuously delivering the compressor shells to be processed to the designated area.

[0032] In this embodiment, the housing positioning unit 30 specifically adopts an electromagnetic suction cup or a pneumatic suction cup 30a to reliably and quickly grasp and release the compressor housing. Figure 2 As shown, the core components of the linear drive device 40 include a motor and a rack 41. The motor is used as a power source to drive the rack 41 to perform precise linear motion along the first direction; and the shell positioning unit 30 preferably adopts a pneumatic suction cup 30a to firmly adsorb the compressor shell using the principle of vacuum adsorption.

[0033] During operation, after the conveyor belt 20 accurately transports a compressor casing to the preset grabbing position, the control system will issue a command, and the pneumatic suction cup 30a installed on the rack 41 will drop rapidly and reliably adsorb the compressor casing on the conveyor belt 20. Subsequently, the rack 41 connected to the pneumatic suction cup 30a is driven by the motor to move smoothly along the first direction, and accurately transport the casing to the top of the first burr removal component 100. During this process, the pneumatic suction cup 30a usually maintains a uniform speed to ensure that the blade of the compressor casing can smoothly pass through each burr removal component 100 and undergo continuous processing. After the burr removal process of all workstations is completed, the linear drive device 40 will continue to drive the pneumatic suction cup 30a to move the processed casing to the subsequent workstation or unloading area to complete the entire conveying process.

[0034] In another embodiment, if Figure 3 、 Figure 4 、 Figure 5As shown, the housing positioning unit 30 includes two bases 31 arranged opposite to each other, the upper surface of the base 31 is provided with a connection structure connected to the linear drive device 40, and the lower surface of the base 31 is slidably mounted with a follower 32; the follower 32 slides relative to the base 31 and has a second direction perpendicular to the first direction; a guide pulley 33 is rotatably mounted on the side of the follower 32 away from the second direction, and the axial direction of the guide pulley 33 is perpendicular to the second direction; the side of the follower 32 away from the guide pulley 33 is rotatably mounted A V-shaped clamp 34 is detachably mounted on the side, and the V-shaped clamp 34 has a clamping opening for clamping the compressor casing, and the opening direction of the clamping opening is consistent with the second direction; a return spring 35 is also provided between the base 31 and the follower 32, which enables the follower 32 to slide to the side away from the second direction and maintain it in a predetermined position when no external force is applied; the two bases 31 are respectively located on both sides of the conveyor belt 20, and the two sides of the conveyor belt 20 are provided with guide rails 300 extending along the first direction and matching the guide pulley 33.

[0035] In the specific implementation, in the initial state, if Figure 3 As shown, the two bases 31 are respectively on both sides of the conveyor belt 20, and the upper surface of the base 31 is reliably connected to the linear drive device 40 through a connecting structure, such as bolts and other fasteners, to ensure that the two can move synchronously and coordinately along the first direction. At this time, the force of the return spring 35 keeps the follower 32 in a position away from the second direction, and the two V-shaped clamps 34 are therefore in a state of being away from each other and do not contact the compressor housing on the conveyor belt 20; as the linear drive device 40 continues to drive the base 31 to move forward along the guide rail 300, the guide pulley 33 fixed to the follower 32 gradually establishes contact with the guide rails 300 preset on both sides of the conveyor belt 20, and the inner side of the guide rail 300 The surface will apply a force toward the conveyor belt 20 to the rolling guide pulley 33, which effectively compresses the return spring 35 and forces the follower 32 to slide in the second direction (i.e., toward the compressor housing). As the follower 32 slides in the second direction, the V-shaped clamp 34 fixed thereon also moves inward, and the clamping openings opposite to each other gradually approach and eventually firmly clamp the compressor housing located on the conveyor belt 20. Once the compressor housing is firmly clamped, the linear drive device 40 can accurately drive the entire V-shaped clamp 34 and the compressor housing firmly fixed by it to move smoothly to the working station where the burr removal component 100 is located for subsequent deburring process.

[0036] After completing the deburring operation, the linear drive device 40 continues to pull the base 31 forward until the guide pulley 33 is completely free from the constraint of the guide rail 300. At this moment, the previously compressed return spring 35 quickly releases its stored energy, pushing the follower 32 to slide rapidly in a direction away from the second direction, directly causing the V-shaped clamp 34 to loosen its grip on the compressor housing. The compressor housing that has lost its constraint will naturally fall back to the conveyor belt 20, or be received by the mechanism of the subsequent workstation, thereby completing the unloading process.

[0037] In some embodiments, as Figure 3 As shown, the end of the V-shaped clamp 34 has a rounded transition. Sharp edges can easily cause localized stress concentration when in contact with the compressor housing, potentially leading to scratches or scrapes on the housing surface, affecting product appearance and quality. However, the rounded transition increases the contact area and disperses the pressure, effectively avoiding such surface damage and improving product quality.

[0038] In some embodiments, as Figure 4 As shown, a rotatable roller 36 is provided at the end of the V-shaped clamp 34. The roller 36 is configured to contact the compressor housing and is made of a rubber material. The rubber roller 36 has a certain degree of elasticity, which allows it to better adapt to minor unevenness on the compressor housing surface, reducing wear and scratches that may be caused by hard contact. The cushioning properties of the rubber also absorb some impact force, further protecting the housing surface.

[0039] In some embodiments, as Figure 4 As shown, it also includes an L-shaped connecting plate 50 and at least two threaded columns 60. The V-shaped clamp 34 is detachably fixed to the first side plate of the L-shaped connecting plate 50; the threaded column 60 is arranged on the second side plate of the L-shaped connecting plate 50; the follower 32 is provided with a screw hole adapted to the threaded column 60, and the threaded column 60 is connected to the follower 32 through the screw hole.

[0040] In specific implementation, by rotating the threaded column 60 on the L-shaped connecting plate 50, the initial position of the V-shaped clamp 34 in the first direction can be easily fine-tuned. This design provides a simple and effective adjustment method. For example, when it is necessary to clamp a smaller compressor housing, the threaded column 60 can be unscrewed slightly, so that the initial position of the V-shaped clamp 34 in the first direction moves outward (close to the side of the compressor housing), thereby reducing the initial width distance between the two clamping openings; conversely, when it is necessary to clamp a larger compressor housing, the threaded column 60 can be screwed in slightly, so that the initial position moves inward, thereby increasing the initial width of the clamping opening. In this way, the V-shaped clamp 34 can achieve adaptive clamping of compressor housings of different specifications without adjusting the installation position of the entire base 31, thereby improving the versatility and flexibility of the device, simplifying the operating steps, and shortening the adjustment time of the production line.

[0041] In some embodiments, as Figure 4 As shown, the follower 32 is provided with a wheel frame 70, which is provided with a vertical axle. The guide pulley 33 is coaxially fixed to the axle. The guide pulley 33 is a waist drum. The shape of the waist drum provides a self-centering function. When the guide pulley 33 moves on the guide rail 300, even if the installation position of the guide rail 300 deviates slightly, the waist drum can automatically adjust due to its special curved surface, ensuring that the guide pulley 33 always remains in the correct guide rail position, reducing movement deviation caused by guide rail installation errors.

[0042] In some embodiments, as Figure 5 As shown, the base 31 has a slot defined on its lower surface, within which a guide rod 80 extending in the second direction is disposed. The follower 32 has a guide portion that slidably engages the slot, and the guide portion defines a sliding hole that mates with the guide rod 80. A return spring 35 is disposed within the slot and sleeved onto the guide rod 80, with both ends of the return spring 35 abutting against the guide portion and the slot wall of the slot. The guide rod 80 provides precise guidance for the follower 32 within the slot, ensuring that the follower 32 can only move linearly along the predetermined second direction, effectively preventing deflection or jamming during movement and improving the smoothness and reliability of movement. The guide rod 80 also limits lateral movement of the return spring 35 during compression and release, effectively preventing bending or jamming of the return spring 35. This ensures the stable and reliable performance of the return spring 35, enabling it to continue to function effectively and accurately, and ensuring that the V-shaped chuck 34 can move accurately and reliably when needed.

[0043] The compressor casing blade burr removal mechanism provided in this embodiment significantly improves the burr removal efficiency and shortens the production cycle by adopting multi-station synchronous processing and continuous conveying. It combines precise positioning clamping with a stable and reliable grinding method to ensure high precision and high quality of burr removal, avoids excessive or insufficient grinding, and significantly reduces labor costs and equipment maintenance costs; at the same time, the mechanism has good adaptability and can meet the burr removal needs of compressor casings of different sizes and shapes.
