Description

Technical Field

[0001] The utility model relates to the technical field of compressor housing manufacturing equipment, in particular to a compressor housing burr removal device. Background Art

[0002] In modern compressor manufacturing, the compressor housing, a core component, undergoes multiple critical processes, including stamping, casting, and machining. Material transfer between these processes, particularly the efficient and stable handling of irregularly shaped, semi-finished housings, has long been a significant bottleneck restricting production efficiency, directly impacting production costs and product quality.

[0003] Currently, the methods used for clamping, handling, and deburring compressor casings are gradually exposing their inherent limitations when dealing with increasingly complex product shapes and diverse specifications. This is reflected in the following key aspects:

[0004] First, in terms of clamping and handling of the shell, it is difficult for existing technologies to strike a balance between versatility and stability. That is, the compressor shell usually presents non-standard geometric shapes such as semi-ovals and special-shaped curved surfaces, rather than regular circles or squares. This directly leads to the difficulty of traditional general-purpose clamping tooling to achieve stable and reliable grasping and fixing. For example, the design concept of the currently common claw-type or chuck-type fixtures often relies on the force clamping of the workpiece surface with regular shapes. Therefore, precise customized design is required for compressor shells of specific shapes. Secondly, this customized solution not only has poor versatility and is difficult to meet the needs of mass and flexible production, but also requires frequent replacement of tooling, which significantly increases production preparation time and cost. More importantly, for the clamping of irregular shapes, if the clamping force is unevenly distributed or the contact area is insufficient, it is very easy to cause unstable clamping, resulting in the shell slipping, offsetting, and even causing damage due to bumps during transportation, seriously affecting production efficiency and the quality of the final product, and also posing potential safety hazards. Moreover, due to the large number of compressor product models, the corresponding shells have significant differences in size, geometry, weight, etc., further highlighting the versatility problem of traditional clamping tooling. Therefore, in order to adapt to shells of different specifications, the production line often needs to be equipped with a wide variety of special clamps, which not only greatly increases production costs and tooling maintenance and management costs, but also significantly extends the adjustment and preparation cycle of the production line.

[0005] Secondly, when it comes to deburring the compressor housing, existing technologies struggle to balance efficiency and quality. Deburring the compressor housing is a critical process that directly impacts the performance and lifespan of the compressor. Currently, many manufacturers still rely on manual grinding with a grinding wheel for deburring. This method is not only inefficient and labor-intensive, but also suffers from unstable grinding quality, making it difficult to ensure consistency and easily damaging the housing. While methods like mechanical milling are more efficient, they lack precision, are prone to generating new burrs, and require frequent tool changes, resulting in high production costs. Furthermore, while some chemical corrosion methods can remove fine burrs, they can cause environmental pollution, and the degree of corrosion is difficult to control.

[0006] In summary, the existing technology has significant bottlenecks in the clamping, handling and burr removal of the compressor housing, which seriously restricts the improvement of compressor production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0031] 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.

[0032] like Figures 1 to 11As shown, the compressor casing deburring device described in this embodiment is primarily used to automatically remove burrs generated during the compressor casing manufacturing process. The device includes a loading assembly 100, a casing clamping assembly 200, a burr removal assembly 300, and a discharge assembly 400, arranged sequentially along the conveying direction. These components work together to achieve automated and continuous deburring of the compressor casing.

[0033] Among them, the loading assembly 100 is mainly responsible for delivering the scattered compressor casings to the subsequent workstations in an orderly manner. Specifically, the loading assembly 100 includes a loading guide rail 110, and the loading guide rail 110 is provided with an empty slot 120 extending along the loading guide rail 110. A first circulating drive chain 130 is provided below the loading guide rail 110, and a plurality of follower rods 140 are evenly spaced on the chain links of the first circulating drive chain 130. A portion of the follower rod 140 extends from the empty slot 120 and abuts against the bottom of the compressor casing placed on the loading guide rail 110, and is configured to push the compressor casing along the loading guide rail 110 to a predetermined clamping position under the drive of the first circulating drive chain 130. With this structural design, when the first circulating drive chain 130 starts to operate, the follower rod 140 will continue to push the compressor housing to slide along the track of the loading guide rail 110, and finally smoothly transport it to the designated clamping position. That is, the follower rod 140 does not directly push the compressor housing, but only contacts the empty bottom of the compressor housing. This design allows the housing to slide smoothly on the loading guide rail 110, rather than being directly pushed and moved by the follower rod 140, reducing the risk of damage to the exterior surface of the housing and improving the smoothness of the transportation process. In this embodiment, a silicone sleeve is provided on the follower rod 140. The silicone has soft properties and can effectively cushion the contact impact between the follower rod 140 and the compressor housing, preventing damage such as scratches, scrapes or bumps on the surface of the housing due to hard contact during transportation.

[0034] The shell clamping assembly 200 is mainly responsible for clamping the compressor shell and conveying it to the subsequent burr removal station. Specifically, the shell clamping assembly 200 includes a second circulating drive chain 210, a first guide rail 220 and a chuck assembly 230. The second circulating drive chain 210 and the first guide rail 220 are both provided with two at intervals along the conveying direction. The chuck assembly 230 is fixed to the chain link of the second circulating drive chain 210 through a connecting piece 240, and the chuck assembly 230 is provided in pairs and arranged at intervals on the second circulating drive chain 210 along the conveying direction; the chuck assembly 230 includes two oppositely arranged bases 231, the upper surface of the base 231 is connected to the connecting piece 240, and the lower surface of the base 231 is slidably mounted with a follower 232; the follower 232 is relatively It slides on the base 231 and has a clamping direction perpendicular to the conveying direction; a guide pulley 233 is rotatably mounted on the side of the follower 232 away from the clamping direction, and the axial direction of the guide pulley 233 is perpendicular to the clamping direction and cooperates with the first guide rail 220; a V-shaped clamp 234 is detachably mounted on the side of the follower 232 away from the guide pulley 233, and the V-shaped clamp 234 has a clamping opening for clamping the compressor housing, and the opening direction of the clamping opening is consistent with the clamping direction; a return spring 235 is also provided between the base 231 and the follower 232, which enables the follower 232 to slide toward the side away from the clamping direction and remain in a predetermined position when no external force is applied.

[0035] Using this structural design, Figure 1 、 Figure 4 、 Figure 7 、 Figure 11As shown, the compressor housing moves smoothly to the predetermined clamping position under the conveyance of the loading assembly 100. At this time, the second circulating drive chain 210 located on both sides of the loading assembly 100 starts to work, driving the clamping head assembly 230 installed thereon to move toward the compressor housing. In the initial state, the return spring 235 makes the follower 232 in a position away from the clamping direction, that is, the V-shaped clamp 234 keeps a certain distance from the compressor housing and is in a loose state, avoiding contact and collision; and as the second circulating drive chain 210 drives the base 231 to move along the first guide rail 220, it also synchronously drives the follower 232 to move along the conveying direction. When the follower 232 continues to move, the guide pulley 23 3 will gradually come into contact with the first guide rail 220. At this time, the first guide rail 220 will apply a force to the guide pulley 233 in the opposite direction of the clamping direction of the follower 232. This force will gradually compress the return spring 235 and prompt the follower 232 to move along the clamping direction. As the follower 232 moves along the clamping direction, the V-shaped clamp 234 installed thereon also moves inward. The two clamping openings on both sides gradually approach and firmly clamp the compressor housing. Once the compressor housing is firmly clamped, the second circulating drive chain 210 can drive the clamp assembly 230 and the compressor housing to move together and move them in the air above the burr removal assembly 300 for subsequent burr removal process.

[0036] The burr removal assembly 300 is mainly responsible for removing burrs on the compressor housing. Specifically, a plurality of burr removal assemblies 300 are arranged at intervals below the second circulating drive chain 210 along the conveying direction. Each burr removal assembly 300 includes a turntable 310, a drive motor arranged on the table of the turntable 310, and a gauze wheel 320 coaxially fixedly mounted on the drive shaft of the drive motor; the gauze wheel 320 is configured to rotate synchronously with the drive motor under the drive of the turntable 310 and contact the compressor housing clamped by the chuck assembly 230; the blanking assembly 400 is connected to the output end of the housing clamping assembly 200.

[0037] With this structural design, the turntable 310 can drive the entire drive motor and the gauze wheel 320 to rotate horizontally synchronously. This rotation method can make the gauze wheel 320 more fully contact with the blade of the compressor housing, improve the burr removal effect, and make the gauze material of the gauze wheel 320 effectively grind off the burrs on the blade, that is, when the compressor housing moves along the clamping direction driven by the housing clamping assembly 200, its blade will contact the gauze surface of multiple rotating gauze wheels 320 in turn, thereby After the burr removal process is completed, the second circulating drive chain 210 continues to drive the base 231 to move until the guide pulley 233 is free from the constraint of the first guide rail 220. At this time, the return spring 235, which has lost the external force, will be quickly released, pushing the follower 232 to slide in the direction away from the clamping. The movement of the follower 232 will directly cause the V-shaped clamp 234 to release the compressor housing, allowing the compressor housing to fall freely on the blanking assembly 400 under its own weight, thus completing the blanking process. This cycle is repeated to achieve continuous automatic transportation of the compressor housing.

[0038] In some embodiments, as Figure 1 、 Figure 6 、 Figure 7 As shown, the coupling member 240 includes a first arm 241 fixedly connected to a link of the second endless drive chain 210, and a second arm 242 fixedly connected to the base 231. The first arm 241 and the second arm 242 are arranged parallel and opposite each other to form clearance spaces 243. A second guide rail 250 extending in the conveying direction is disposed below the second endless drive chain 210 and passes through each of the clearance spaces 243. A guide wheel 244 is pivotally connected to the end of the first arm 241, which contacts the upper rail surface of the second guide rail 250. This structural design ensures that when the chuck assembly 230 moves to the second half of its travel along the second endless drive chain 210, the second guide rail 250 can precisely pass through the clearance spaces 243 formed between the first arm 241 and the second arm 242 of the coupling member 240. Furthermore, a cylindrical guide wheel 244 is pivotally connected to the distal end of the first arm 241 via a bearing or other means. The outer circumferential surface of the guide wheel 244 is in rolling contact with the upper surface of the second guide rail 250 .

[0039] During specific operation, when the clamping assembly 230 moves downward with the second circulating drive chain 210, the guide wheel 244 will gradually contact the upper surface of the second guide rail 250. The second guide rail 250 will then provide an upward supporting force for the guide wheel 244. This supporting force is transmitted to the entire clamping assembly 230 through the first arm 241, thereby effectively bearing part of the weight of the clamping assembly 230 and the compressor casing it clamps. This means that the load originally borne by the second circulating drive chain 210 alone is now shared by the second guide rail 250, thereby significantly reducing the carrying load of the second circulating drive chain 210, reducing the wear and energy consumption of the drive chain, and extending the service life of the drive chain. In addition, the cooperation between the second guide rail 250 and the guide wheel 244 provides additional guidance for the movement of the chuck assembly 230. Specifically, the rolling contact between the guide wheel 244 and the second guide rail 250 effectively limits the vertical shaking of the chuck assembly 230, making the movement of the chuck assembly 230 more stable and reliable in the second half of its travel, avoiding deviation or impact that may be caused by inertia or vibration, and improving the stability and accuracy of the transfer. This additional guidance not only ensures that the chuck assembly 230 can accurately reach the predetermined position, but also provides a reliable guarantee for the subsequent burr removal process. This supporting and guiding role is particularly significant when clamping a heavy compressor casing, effectively preventing the drive chain from shaking or deforming due to excessive load, thereby improving the stability and reliability of the equipment.

[0040] In some embodiments, as Figure 1 As shown, a third guide rail 260 extending in the conveying direction is provided above the second circulating drive chain 210; when the second circulating drive chain 210 drives the chuck assembly 230 to move above it, the guide wheel 244 contacts the upper rail surface of the third guide rail 260. Similar to the second guide rail 250, the third guide rail 260 also mainly plays a dual role of support and guidance. Specifically, when the chuck assembly 230 is driven by the second circulating drive chain 210 and gradually moves above the second circulating drive chain 210, the weight of the chuck assembly 230 and the compressor housing it clamps will be transferred to the third guide rail 260 through the guide wheel 244. The third guide rail 260 will bear this part of the weight, so as to further reduce the pulling load of the second circulating drive chain 210, so that the drive chain is more evenly stressed during the entire circulation process, and effectively avoid the occurrence of excessive local stress.

[0041] In some embodiments, as Figure 1 、 Figure 4 、 Figure 6 、 Figure 7As shown, it also includes an L-shaped connecting plate 236 and at least two threaded columns 237. The V-shaped clamp 234 is detachably fixed to the first side plate of the L-shaped connecting plate 236; the threaded column 237 is arranged on the second side plate of the L-shaped connecting plate 236; the follower 232 is provided with a threaded hole adapted to the threaded column 237, and the threaded column 237 is connected to the follower 232 through the threaded hole.

[0042] In specific implementation, by rotating the threaded column 237 on the L-shaped connecting plate 236, the initial position of the V-shaped clamp 234 in the clamping direction can be easily fine-tuned. This design provides a simple and effective adjustment method, for example,

[0043] When it is necessary to clamp a compressor housing of smaller specifications, the threaded column 237 can be unscrewed a little, so that the initial position of the V-shaped clamp 234 in the clamping direction moves outward, that is, closer to the compressor housing, thereby reducing the initial width distance between the two clamping openings, so that the V-shaped clamp 234 can accurately clamp the smaller-sized housing; conversely, when it is necessary to clamp a compressor housing of larger specifications, the threaded column 237 can be screwed in a little, so that the initial position of the V-shaped clamp 234 in the clamping direction moves inward, thereby increasing the initial width of the clamping opening, so that it can adapt to the larger-sized housing. This adjustable design means that the clamp assembly 230 does not need to be frequently replaced for compressor housings of different specifications, nor does it need to adjust the installation position of the entire base 231, so that adaptive clamping of compressor housings of different specifications can be achieved, thereby significantly improving the versatility and flexibility of the device, greatly simplifying the operating steps, and shortening the adjustment time of the production line.

[0044] In some embodiments, as Figure 7 、 Figure 11As shown, a slide groove 2311 is provided on the lower surface of the base 231, and a guide rod 2312 extending along the clamping direction is provided in the slide groove 2311; the follower 232 has a guide sliding portion 2321 that slides with the slide groove 2311, and the guide sliding portion 2321 is provided with a sliding hole that is adapted to the guide rod 2312; a reset spring 235 is arranged in the slide groove 2311 and is sleeved on the guide rod 2312, and the two ends of the reset spring 235 respectively abut against the guide sliding portion 2321 and the groove wall of the slide groove 2311. In actual operation, when the clamp assembly 230 moves along the second circulating drive chain 210 to the position where the compressor housing needs to be clamped, the return spring 235 is compressed, and the follower 232 slides along the guide rod 2312 and the slide groove 2311, thereby driving the V-shaped clamp 234 to move inward to clamp the compressor housing; and when the clamp assembly 230 completes the clamping task, the guide pulley 233 is disengaged from the constraint of the first guide rail 220, and the return spring 235 quickly releases energy, pushing the follower 232 to slide in the opposite direction along the guide rod 2312 and the slide groove 2311, so that the two V-shaped clamps 234 open and prepare for the next clamping action, wherein the guide rod 2312 can provide reliable guidance for the follower 232 during this reciprocating sliding process, ensuring that the follower 232 can only move along the predetermined straight line direction to avoid any lateral offset. In addition, the reset spring 235 is sleeved on the guide rod 2312, which can prevent the reset spring 235 from unnecessary shaking, thereby ensuring that the reset spring 235 is evenly stressed, avoiding performance degradation or damage caused by uneven stress, and ensuring the stability and reliability of the reset process.

[0045] In some embodiments, as Figure 2 、 Figure 3 、 Figure 9As shown, a first connecting plate 131 extending horizontally outward is fixed on the link of the first circulating drive chain 130, and a second connecting plate 141 is provided at the bottom end of the follower rod 140. The first connecting plate 131 and the second connecting plate 141 are provided with at least two threaded holes along the length direction of the link, and the first connecting plate 131 and the second connecting plate 141 are fixed by threading through the threaded holes with bolts. This bolt connection method not only makes the installation and disassembly of the follower rod 140 very convenient without the need for complex tools, but also provides the possibility of adjusting the position of the follower rod 140. For example, when it is necessary to transport different compressor housings, it is only necessary to loosen the bolts on the second connecting plate 141, select the threaded holes on the first connecting plate 131 of the appropriate chain link, and retighten the bolts to complete the adjustment. This feature can facilitate the rapid switching of the production line according to different compressor housing sizes or shapes, thereby improving the flexibility and adaptability of the production line. In addition, since this structure uses common bolt connections, its manufacturing cost is low and maintenance is more convenient and quick. It can also ensure that the follower rod 140 will not loosen or fall off when the circulating drive chain 30 runs at high speed, thereby ensuring the stability and reliability of the feeding mechanism.

[0046] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 As shown, the loading guide rail 110 includes a first inclined section 111 extending obliquely downward, a first horizontal section 112, a second inclined section 113 extending obliquely upward, and a second horizontal section 114. The first horizontal section 112 is connected between the first inclined section 111 and the second inclined section 113. The empty groove 120 extends from the connection position between the first horizontal section 112 and the first inclined section 111 to the connection position between the second inclined section 113 and the second horizontal section 114. There are smooth rounded transitions between the first inclined section 111 and the first horizontal section 112, between the first horizontal section 112 and the second inclined section 113, and between the second inclined section 113 and the second horizontal section 114.

[0047] Specifically, the compressor casing can be manually dropped or fed into the first inclined section 111 of the feeding guide rail 110 through a conveyor belt. In order to pre-process the incoming compressor casing more effectively, in this embodiment, a shell supply vibration plate 115 is connected to the entrance of the first inclined section 111, that is, the shell supply vibration plate 115 is used to generate continuous vibration to sort out the originally scattered and piled compressor casing materials, so that they are gradually arranged in an orderly manner under the action of vibration, and enter the first inclined section 111 of the feeding guide rail 110 in a suitable posture; at the same time, the vibration of the shell supply vibration plate 115 can also effectively prevent the casing from piling up and clogging at the entrance of the first inclined section 111, thereby ensuring that the compressor casing can continuously and evenly enter the feeding guide rail 110, avoiding the interruption or jamming of transportation due to the accumulation of the casing.

[0048] After being pre-processed by the shell vibration plate 115, the compressor shell enters the first inclined section 111 and, under the action of gravity, will naturally slide down along the first inclined section 111 extending obliquely downward, and finally enter the first horizontal section 112 in a relatively stable posture. In the first horizontal section 112, the shell will smoothly enter the second inclined section 113 with the help of inertia in a stable posture and direction, and reliably abut with the follower rod 140 on the first circulating drive chain 130, thereby being driven by the follower rod 140 to enter the second horizontal section 114 whose height is adapted to the shell clamping assembly 200, and start the subsequent burr removal process. In addition, the smooth transition of the rounded corners between the sections not only avoids collision and wear of the shell at the turning point, but also ensures that the shell can move smoothly and continuously without worrying about jamming or deviation from the track.

[0049] In some embodiments, as Figure 3 As shown, it also includes a first compression shell arc plate 150 with an arc-shaped structure. The first compression shell arc plate 150 is arranged above the second horizontal section 114, and one end of the first compression shell arc plate 150 facing the second inclined section 113 is pivotally connected to the external support structure; when the follower rod 140 on the circulating drive chain drives the compressor casing to run to the second horizontal section 114, the other end of the first compression shell arc plate 150 is pressed onto the compressor casing that has been separated from the follower rod 140.

[0050] During operation, when the follower rod 140 on the circulating drive chain 130 pushes the compressor housing to the second horizontal section 114, the compressor housing may jump or flip due to inertia. At this time, the other end of the first compression shell arc plate 150 will use its own gravity to press against the compressor housing that has been separated from the follower rod 140, thereby effectively suppressing the jumping and flipping of the housing, so that the compressor housing can be clamped by the clamping head assembly 230 in a more stable posture. It is particularly important to point out that the pressing action of the first compression shell arc plate 150 and the housing occurs after the housing is separated from the follower rod 140. This design ensures that the first compression shell arc plate 150 will not interfere with the pushing action of the follower rod 140 on the housing during the transportation of the compressor housing. Instead, it plays a stabilizing and guiding role only when the compressor housing reaches the second horizontal section 114 and is about to enter the clamping station, thereby ensuring the reliability and accuracy of the loading and conveying process. In addition, the first compression shell arc plate 150 adopts an arc-shaped structure, which can ensure that its contact with the compressor housing is softer, thereby reducing wear on the surface of the compressor housing.

[0051] In some embodiments, as Figure 1 As shown, the blanking assembly 400 includes a blanking guide rail 410 and a second compression shell arc plate 420 with an arc-shaped structure. The blanking guide rail 410 includes a third inclined section 411 extending obliquely downward and a third straight section 412 extending horizontally. The upper end of the third inclined section 411 is connected to the output end of the shell clamping assembly 200, and the lower end is connected to the third straight section 412; the third straight section 412 is connected to the external collecting frame 430; the second compression shell arc plate 420 is arranged above the third inclined section 411, and one end of the second compression shell arc plate 420 facing the compressor shell conveying mechanism is fixed to the external support structure through a pivot structure, and the other end is pressed against the compressor shell on the inclined blanking guide rail 410 under the action of gravity; wherein, the end of the second compression shell arc plate 420 pressed against the compressor shell is located in the middle position of the third inclined section 411 or near the middle position of the lower end of the third inclined section 411.

[0052] During specific operation, when the housing clamping assembly 200 transports the compressor housing to the unloading station according to a predetermined beat, the compressor housing that has been deburred will fall from between the two oppositely arranged clamping head assemblies 230 and slide into the third inclined section 411 of the unloading guide rail 410. At this time, the second compression shell arc plate 420 located above the third inclined section 411 will always be stably pressed on the sliding compressor housing under the action of its own gravity, forming a controllable resistance. This design can effectively control the compressor housing in the third inclined section 4 The sliding speed on 11 significantly avoids the potential impact and collision risks caused by the free rolling or rapid sliding of the compressor housing due to gravity, thereby maximally protecting the surface of the compressor housing, preventing scratches or damage, and ensuring the smoothness and safety of the unloading process. As the compressor housing continues to slide along the third inclined section 411 and gradually enters the horizontal third straight section 412, the falling speed will be further alleviated, and the compressor housing will eventually slide into the external collection frame 430 in a stable posture, completing the unloading process and waiting for subsequent picking and placement.

[0053] In other embodiments, Figure 8 As shown, the side edges of the second inclined section 113 and the third inclined section 411 can be removably installed with limiting edges 1131. In this way, by using the removably installed limiting edges 1131, the track widths of the second inclined section 113 and the third inclined section 411 can be adapted to the width of the compressor casing by simply adjusting the installation position of the limiting edges 1131, so as to effectively constrain the movement trajectory of the casing on the second inclined section 113 and the third inclined section 411, prevent the casing from deviating, shaking or even overturning during the sliding process, ensure the safe and reliable transportation of the casing to the subsequent workstation, and reduce the production interruption or quality problems that may be caused by unstable casing posture.

[0054] In some embodiments, as Figure 6 、 Figure 7 As shown, the end of the V-shaped clamp 234 has a rounded transition; or the end of the V-shaped clamp 234 is provided with a rubber block 238. In actual operation, when the V-shaped clamp 234 clamps the compressor housing, if a traditional sharp edge design is used, it is easy to cause scratches, scrapes or deformation to the surface of the compressor housing due to excessive stress concentration. The rounded transition design can reduce the stress concentration at the contact between the clamp and the housing, disperse the impact force, and thus avoid damage to the housing surface. The V-shaped clamp 234 using the rubber block 238 can use the elasticity of the rubber block to absorb the impact and vibration generated during the clamping process. At the same time, the friction of the rubber block can also increase the stability of the clamping and avoid sliding. In addition, the softness of the rubber block can effectively protect the surface of the housing and avoid scratches and scrapes.

[0055] Through these two designs, the V-shaped clamp 234 can clamp the compressor housing more safely and reliably and provide it with good protection, thereby avoiding bumps and damages caused by improper clamping and improving the product yield.

[0056] The compressor casing deburring device provided in this embodiment realizes the automation and continuity of the compressor casing deburring process by integrating multiple links such as loading, clamping, burr removal and unloading, thereby significantly improving production efficiency; the follower rod and the loading mechanism of the inclined guide rail adopted by it can transport scattered casings to the clamping station in an orderly manner, effectively avoiding the problems of low efficiency and unstable posture caused by the traditional manual loading method; at the same time, the use of an adjustable clamping mechanism can effectively cope with compressor casings of different specifications and shapes, improve the versatility of the equipment, and do not need to frequently change the clamps, thereby shortening the production preparation time and reducing The rotatable gauze wheel burr removal mechanism is designed to coordinate with the clamping mechanism to remove burrs on the blade of the compressor casing efficiently and evenly, avoiding problems such as over-grinding, insufficient grinding or secondary burrs that may be caused by traditional manual grinding or mechanical milling methods, and significantly improving processing accuracy and surface quality; in addition, through the precise guidance of the guide rail and the auxiliary suppression of the compression shell arc plate, it ensures that the casing always maintains a stable posture during transportation, avoiding bumps or damage, further improving the product qualification rate, and ultimately achieving a comprehensive improvement in production efficiency, product quality and production safety.
