Description

Technical Field

[0001] The invention relates to the technical field of compressor housing manufacturing equipment, in particular to a method for removing burrs from a compressor housing. Background Art

[0002] In the modern compressor manufacturing process, the compressor housing, as a core component, needs to go through multiple key processes such as stamping, casting, machining, etc. The material transfer between these processes, especially the efficient and stable handling of irregularly shaped semi-finished housings, has long been an important bottleneck restricting the improvement of production efficiency and directly affecting production costs and product quality.

[0003] At present, the methods used for clamping, handling and deburring compressor housings are gradually exposing their inherent limitations in response to increasingly complex product shapes and diverse specification requirements, which are specifically reflected in the following key aspects:

[0004] First, in terms of the clamping and handling of the shell, the existing technology is difficult to balance versatility and stability. That is, the compressor shell usually presents non-standard geometric shapes such as semi-ellipse and special-shaped curved surface, rather than regular circle or square. 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 common claw-type or chuck-type clamps often relies on the force clamping of the workpiece surface with regular shape. Therefore, it is necessary to carry out precise customized design for the compressor shell of a specific shape. This customized solution is not only poor in versatility, but also difficult to meet the needs of mass production and flexible production, resulting in the need for frequent replacement of tooling, which significantly increases the 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, displacement, and even collision damage during transportation, which seriously affects the production efficiency and the quality of the final product, and also brings 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 the production cost and the maintenance and management cost of the tooling, but also significantly prolongs the adjustment and preparation cycle of the production line.

[0005] Secondly, in terms of burr removal from the shell, the existing technology is difficult to balance efficiency and quality. That is, burr removal from the compressor shell is an important process that directly affects the performance and life of the compressor. At present, many manufacturers still use manual grinding wheel grinding to remove burrs. This method is not only inefficient and labor-intensive, but also has unstable grinding quality, making it difficult to ensure consistency and easily causing damage to the shell. Although methods such as mechanical milling are more efficient, the processing accuracy is not high, new burrs are easily generated, and the tool needs to be replaced frequently, resulting in high production costs. In addition, although some methods such as chemical corrosion can remove fine burrs, they will 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 the compressor production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0042] 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.

[0043] like Figures 1 to 12 As shown, the compressor housing burr removal method described in this embodiment includes the following steps:

[0044] S1. The compressor casing to be processed is transported to a predetermined clamping position along a loading guide rail 110; wherein the loading guide rail 110 is provided with an empty groove 120 extending along the same, and a follower rod 140 is provided in the empty groove 120, and a portion of the follower rod 140 extends from the bottom of the compressor casing into the compressor casing, and is configured to push the compressor casing to move along the loading guide rail 110 under the drive of a first circulating drive chain 130 arranged below the loading guide rail 110.

[0045] During specific implementation, a vibration plate (not shown) can be used to generate continuous vibration to sort out the scattered compressor casings, so that they are gradually arranged in order and enter the loading guide rail 110 in a suitable posture, and multiple follower rods 140 are fixed at equal intervals on the first circulating drive chain 130 located below the loading guide rail 110, and a part of the follower rod 140 extends upward from the empty groove 120 and abuts against the bottom of the compressor casing on the loading guide rail 110. When the first circulating drive chain 130 starts to operate and drives the follower rod 140 to move along the track of the loading guide rail 110, the follower rod 140 abuts against the bottom of the compressor casing, pushing the compressor casing to move along the loading guide rail 110, and finally smoothly transporting it to the predetermined clamping position.

[0046] 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 feeding 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 stability of the conveying process. In this embodiment, a silicone sleeve is provided on the follower rod 140. The silicone has a soft property and can effectively buffer the contact impact between the follower rod 140 and the compressor housing, preventing damage such as scratches, scrapes or bumps on the housing surface caused by hard contact during the conveying process.

[0047] S2. The compressor housing is clamped by a clamping head assembly 230 arranged on both sides of the predetermined clamping position, the clamping head assembly 230 is fixed on the second circulating drive chain 210, and is configured to move in mid-air along the conveying direction to the burr removal station under the drive of the second circulating drive chain 210.

[0048] Specifically, if Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the chuck assembly 230 includes:

[0049] A base 231 is fixed to the chain link of the second circulating drive chain 210 through a coupling member 240;

[0050] A follower 232 is slidably disposed on the base 231 and has a clamping direction perpendicular to the conveying direction;

[0051] The guide pulley 233 is rotatably mounted on the follower 232 and is located on a side of the follower 232 away from the clamping direction;

[0052] A V-shaped chuck 234 is detachably mounted on the follower 232 and is located at a side of the follower 232 away from the guide pulley 233;

[0053] A return spring 235 is disposed between the base 231 and the follower 232, and is used to make the follower 232 slide to a side away from the clamping direction and maintain a predetermined clamping position when no external force is applied;

[0054] A first guide rail 220 is disposed on a side of the clamping assembly 230 away from the clamping direction;

[0055] Among them, when the second circulating drive chain 210 drives the clamp assembly 230 to move to the predetermined clamping position, the guide pulley 233 is connected to the first guide rail 220, so that the follower 232 overcomes the elastic force of the return spring 235 and moves along the clamping direction, thereby driving the V-shaped clamp 234 to clamp and transport the compressor casing to the predetermined clamping position.

[0056] In this way, when the compressor housing is conveyed to the predetermined clamping position, at this time, the second circulating drive chain 210 located on both sides of the predetermined clamping position, that is, on both sides of the feeding guide rail 110, 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 maintains 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 forward in the conveying direction. When the follower 232 continues to move, the guide pulley 233 thereon will gradually The guide wheel 233 is gradually brought 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 that is opposite to the clamping direction of the follower 232. This force will gradually compress the reset spring 235 and prompt the follower 232 to move along the clamping direction. Along with the movement of the follower 232 along the clamping direction, the V-shaped clamp 234 installed thereon also moves inward, and the two clamping openings opposite to each other 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 in the air together, even if the blade position at the bottom of the compressor housing is exposed, it is convenient for the subsequent burr removal process.

[0057] S3. The gauze wheel 320 disposed at the burr removal station is brought into contact with the blade of the compressor housing to remove burrs; wherein the gauze wheel 320 is configured to rotate around its own axis under the drive of its driving motor, and to rotate horizontally as a whole under the drive of the turntable 310.

[0058] Specifically, Figure 6As shown, a plurality of turntables 310 and gauze wheels 320 are arranged at intervals below the second circulating drive chain 210 along the conveying direction. With this structural design, the turntable 310 can drive the entire drive motor and the gauze wheels 320 to rotate horizontally synchronously. This rotation method can make the gauze wheels 320 more fully contact with the blade of the compressor housing, thereby improving the burr removal effect, so that the gauze material of the gauze wheels 320 can effectively grind off the burrs on the blade, that is, when the compressor housing moves along the clamping direction, its bottom blade will contact the gauze surfaces of multiple rotating gauze wheels 320 in turn, thereby achieving continuous burr removal.

[0059] S4. The compressor casing after burr removal is clamped and transported to the unloading position and released by the chuck assembly 230, so that the compressor casing slides along the unloading guide rail 410 provided with the first compression shell arc plate 420 into the collecting frame 430; wherein the first compression shell arc plate 420 is arranged above the unloading guide rail 410, and one end of the first compression shell arc plate 420 facing the burr removal station is fixed to the external support structure through a pivot structure, and the other end is pressed against the compressor casing on the unloading guide rail 410 under the action of gravity.

[0060] Specifically, Figure 3 As shown, 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 without external force will be quickly released, pushing the follower 232 to slide away from the clamping direction. The movement of the follower 232 will directly cause the V-shaped clamp 234 to release the compressor housing, so that the compressor housing falls freely on the lower material guide rail 410 under its own gravity, thereby completing the material removal process. This cycle is repeated to achieve continuous and automated transportation of the compressor housing.

[0061] In addition, when the compressor casing that has been deburred will fall from between the two oppositely arranged clamping head assemblies 230 and slide into the unloading guide rail 410, the first compression shell arc plate 420 located above the unloading guide rail 410 will always be stably pressed on the sliding compressor casing under the action of its own gravity, forming a controllable resistance. This design can effectively control the sliding speed of the compressor casing on the unloading guide rail 410, and significantly avoid the potential impact and bump risks caused by the free rolling or rapid sliding of the compressor casing due to gravity, thereby maximally protecting the surface of the compressor casing, preventing scratches or damage, and ensuring the smoothness and safety of the unloading process. As the compressor casing continues to slide along the unloading guide rail 410, it will eventually slide into the external aggregate frame 430 in a stable posture, completing the unloading process and waiting for subsequent picking and placement.

[0062] In some embodiments, Figure 3 , Figure 8 As shown, the coupling member 240 includes a first arm 241 fixedly connected to the link of the second circulating 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 to each other to form a clearance space 243; a second guide rail 250 extending along the conveying direction is arranged below the second circulating drive chain 210, and the second guide rail 250 passes through each of the clearance spaces 243; the end of the first arm 241 is rotatably connected to a guide wheel 244 in contact with the upper rail surface of the second guide rail 250. With this structural design, when the clamp assembly 230 runs to the lower half of its travel along with the second circulating drive chain 210, the second guide rail 250 can just pass through the clearance space 243 formed between the first arm 241 and the second arm 242 of the coupling member 240; at the far end of the first arm 241, a cylindrical guide wheel 244 is pivotally connected through a bearing or the like. The outer circumferential surface of the guide wheel 244 maintains rolling contact with the upper surface of the second guide rail 250 .

[0063] During specific operation, when the clamp 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, and 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 clamp assembly 230 through the first arm 241, thereby effectively bearing part of the weight of the clamp assembly 230 and the compressor housing 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 also provides an additional guiding effect for the movement of the chuck assembly 230, that is, the rolling contact between the guide wheel 244 and the second guide rail 250 effectively limits the shaking of the chuck assembly 230 in the vertical direction, making the movement of the chuck assembly 230 in the second half more stable and reliable, avoiding the deviation or impact caused by inertia or vibration, and improving the stability and accuracy of the transfer. This additional guiding effect 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. Especially when clamping a heavy compressor housing, this supporting and guiding effect is more significant, which can effectively prevent the drive chain from shaking or deforming due to excessive load, thereby improving the stability and reliability of the equipment.

[0064] In some embodiments, Figure 3As shown, a third guide rail 260 extending in the conveying direction is arranged above the second circulating drive chain 210; when the second circulating drive chain 210 drives the clamp 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 clamp assembly 230 is driven by the second circulating drive chain 210 and gradually moves above the second circulating drive chain 210, the weight of itself and the compressor housing clamped by it will be transferred to the third guide rail 260 through the guide wheel 244, and the third guide rail 260 will bear this part of the weight 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 cycle, effectively avoiding the occurrence of excessive local stress.

[0065] In some embodiments, Figure 7 , Figure 8 As 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.

[0066] 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 conveniently 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 237 can be screwed out a little, so that the initial position of the V-shaped clamp 234 in the clamping direction is moved 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 a smaller housing; conversely, when it is necessary to clamp a larger ... V-shaped clamp 234 can be moved outward, When the compressor housing is being clamped, 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 is moved inward, thereby increasing the initial width of the clamping opening, so that it can adapt to a larger size of the housing. This adjustable design makes it unnecessary to frequently replace the clamp assembly 230 for compressor housings of different specifications, and there is no need to adjust the installation position of the entire base 231, so as to achieve adaptive clamping of compressor housings of different specifications, thereby significantly improving the versatility and flexibility of the device, greatly simplifying the operating steps, and shortening the adjustment time of the production line.

[0067] In some embodiments, Fig.11As shown, the V-shaped clamp 234 includes a third arm 2341 and a fourth arm 2342 pivoted to the first side plate, and the third arm 2341 and the fourth arm 2342 are arranged at an angle to form a clamping opening for clamping the compressor housing, and the opening direction of the clamping opening is consistent with the clamping direction; the third arm 2341 and the fourth arm 2342 are pivoted to one end of the first side plate and are provided with mutually meshing gear teeth (not shown in the figure), and the free ends of the third arm 2341 and the fourth arm 2342 are provided with rubber blocks 238. This gear meshing design allows the third arm 2341 and the fourth arm 2342 to maintain synchronous movement during the rotation process, that is, in actual applications, by rotating the third arm 2341 and the fourth arm 2342, the gear meshing structure will drive the other arm to rotate synchronously, so that the opening size of the clamping mouth can be conveniently and quickly adjusted to adapt to compressor housings of different specifications, thereby achieving flexible clamping of housings of different sizes, further improving the versatility and applicability of the device; and the rubber blocks 238 at the free ends of the third arm 2341 and the fourth arm 2342 have a certain elasticity, and will not cause excessive pressure on the surface of the housing even when the clamping force is large, thereby avoiding scratches or scrapes on the surface of the housing during clamping and transportation, and effectively protecting the surface quality of the compressor housing.

[0068] In some embodiments, Figure 7 , Fig.12 As 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 slidably matched with the slide groove 2311, and the guide sliding portion 2321 is provided with a sliding hole adapted to the guide rod 2312; a reset spring 235 is arranged in the slide groove 2311 and 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.

[0069] During operation, when the clamp assembly 230 moves with 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 separated 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 deviation. 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.

[0070] In some embodiments, Figure 3 , Fig.10 As shown, a first connecting plate 131 extending horizontally outward is fixed on the chain 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. At least two threaded holes are provided on the first connecting plate 131 and the second connecting plate 141 along the length direction of the chain link, and the first connecting plate 131 and the second connecting plate 141 are threadedly fixed by bolts passing through the threaded holes.

[0071] This structural design not only makes the installation and removal 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 re-tighten the bolts to complete the adjustment. This feature can facilitate the production line to quickly switch according to different compressor housing sizes or shapes, thereby improving the flexibility and adaptability of the production line. In addition, since the structure adopts common bolt connections, its manufacturing cost is low, maintenance is more convenient and quick, and it can ensure that the follower rod 140 will not loosen or fall off when the circulating drive chain 30 is running at high speed, thereby ensuring the stability and reliability of the feeding mechanism.

[0072] In some embodiments, Figure 2 , Figure 3As 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, and 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.

[0073] Specifically, the compressor housing that enters the first inclined section 111 will naturally slide down along the first inclined section 111 extending obliquely downward under the action of gravity, and will always enter the first horizontal section 112 in a relatively stable posture. In the first horizontal section 112, the housing 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, so that it is driven by the follower rod 140 to enter the second horizontal section 114 whose subsequent height is adapted to the predetermined clamping position, and start the subsequent burr removal process. In addition, the smooth transition of the fillets between the sections not only avoids the collision and wear of the housing at the turning point, but also ensures that the housing can move smoothly and continuously without worrying about jamming or deviation from the track.

[0074] In some embodiments, Figure 4 As shown, it also includes a second compression shell arc plate 150 with an arc-shaped structure. The second compression shell arc plate 150 is arranged above the second horizontal section 114, and one end of the second 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 housing to run to the second horizontal section 114, the other end of the second compression shell arc plate 150 is crimped onto the compressor housing that has been detached from the follower rod 140.

[0075] In specific operation, when the follower rod 140 on the circulating drive chain 130 pushes the compressor housing to run to the second horizontal section 114, due to the effect of inertia, the compressor housing may jump or flip. At this time, the other end of the second compression shell arc plate 150 will use its own gravity to press on 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 clamp assembly 230 in a more stable posture. It is particularly important to point out that the pressing action of the second compression shell arc plate 150 and the housing occurs after the housing is separated from the follower rod 140. This design ensures that the second compression shell arc plate 150 will not interfere with the push of the follower rod 140 on the housing during the transportation of the compressor housing, but only play a stabilizing and guiding role 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 feeding and conveying process. In addition, the second compression shell arc plate 150 adopts an arc-shaped structure, which can ensure that its contact with the compressor housing is softer, thereby reducing the wear on the surface of the compressor housing.

[0076] The compressor casing deburring method provided in the present embodiment realizes the automation and continuity of the compressor casing deburring process by integrating multiple steps such as feeding, clamping, burr removal and unloading, significantly improving production efficiency and reducing manual intervention; the method adopts the feeding step of the follower rod in conjunction with the inclined guide rail, which can orderly transport the scattered compressor casings to the clamping station, effectively avoiding the low efficiency and unstable posture problems of traditional manual feeding; the adjustable clamping mechanism can flexibly cope with compressor casings of different specifications and shapes, improves the versatility of the equipment, and reduces the production preparation time and cost caused by frequent replacement of fixtures; the rotatable gauze wire wheel deburring step can efficiently and evenly remove the burrs on the blade of the compressor casing, avoiding the problems of over-grinding, insufficient grinding or secondary burrs caused by traditional methods, and significantly improving the 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 is ensured that the compressor casing always maintains a stable posture during the transportation process, avoiding bumps and damage, further improving the product qualification rate, and finally achieving a comprehensive improvement in production efficiency, product quality and production safety.
