Description

Technical Field

[0001] The utility model relates to the technical field of compressor housing manufacturing equipment, in particular to a compressor housing clamping and transporting mechanism. Background Art

[0002] In the modern compressor manufacturing process, the compressor housing needs to go through multiple key processes such as stamping, casting, and machining. The material transfer between these processes, especially the efficient handling of irregularly shaped and semi-finished housings, has long been a major bottleneck restricting the improvement of production efficiency. At present, the clamping and handling methods used in the existing technology for compressor housings have gradually exposed their inherent limitations when dealing with increasingly complex product shapes and diverse specification requirements. Specifically, they are reflected in the following key aspects:

[0003] First, compressor housings usually present 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 tools 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 designs are required for compressor housings of specific shapes. This customized solution is not only poor in versatility and difficult to meet the needs of mass and flexible production, but also requires frequent replacement of tooling, which significantly increases production preparation time and costs. More importantly, for 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.

[0004] Secondly, there are many types of compressor products, and the corresponding shells have significant differences in size, geometry, weight, etc., which further highlights the versatility problem of traditional clamping tooling. 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, making it difficult to meet the current manufacturing industry's flexible production needs of multiple varieties, small batches, and rapid switching; and the frequent replacement of tooling operation mode not only directly reduces production efficiency, but also significantly increases the labor intensity of operators, and there is a possibility of equipment or personal safety risks due to operational errors.

[0005] Therefore, in order to break through the existing technical bottleneck and improve the production efficiency of compressors, it is urgent to develop a compressor housing that can effectively cope with irregular shapes and diversified specifications. Utility Model Content

DETAILED DESCRIPTION

[0027] 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.

[0028] The compressor casing clamping and transfer mechanism described in the embodiment of the present application is mainly used in the compressor manufacturing process to realize the automated clamping and transfer of the compressor casing, so as to solve the problem in the prior art that compressor casings with irregular shapes and diverse specifications are difficult to stably clamp and transfer, thereby improving production efficiency.

[0029] like Figures 1 to 6 As shown, the compressor casing clamping and transporting mechanism provided in this embodiment includes:

[0030] The belt conveyor 10 is configured to convey the compressor housing along a conveying direction. The belt conveyor 10 is powered by a motor and is configured to stably convey the compressor housing to be processed along a predetermined conveying direction, providing a basis for subsequent clamping and transfer processes.

[0031] Two reciprocating drive chains 20 are arranged at intervals along the conveying direction, and the two reciprocating drive chains 20 are respectively located on both sides of the belt conveyor 10. The two reciprocating drive chains 20 move synchronously and cyclically to provide driving force for the horizontal movement of the clamping assembly 30.

[0032] The clamping head assembly 30 is fixed to the chain link 21 of the reciprocating drive chain 20 through the coupling 40. The clamping head assembly 30 is arranged in pairs and spaced apart along the conveying direction on the reciprocating drive chain 20. It is used to clamp the compressor housing and move with the drive chain.

[0033] Two first guide rails 50 are provided at intervals along the conveying direction, respectively located on both sides of the chuck assembly 30. They are used to guide the movement of the chuck assembly 30 and ensure that it moves along a predetermined path.

[0034] Among them, the clamping head assembly 30 includes two oppositely arranged bases 31, the upper surface of the base 31 is provided with a connecting structure connected to the connecting member 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 clamping direction perpendicular to the conveying direction; the side of the follower 32 away from the clamping direction is rotatably mounted with a guide pulley 33, the axial direction of the guide pulley 33 is perpendicular to the clamping direction and cooperates with the first guide rail 50; the side of the follower 32 away from the guide pulley 33 is detachably mounted with a V-shaped clamp 34, the V-shaped clamp 34 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 35 is also provided between the base 31 and the follower 32 to enable the follower 32 to slide toward the side away from the clamping direction and maintain it in a predetermined position when no external force is applied.

[0035] When doing specific work, such as Figures 1 to 6 As shown, the compressor housing is transported by the belt conveyor 10 and moves smoothly to the predetermined clamping position. At this time, the reciprocating drive chains 20 located on both sides of the belt conveyor 10 start to work, driving the clamping assembly 30 installed thereon to move toward the compressor housing. In the initial state, the return spring 35 makes the follower 32 in a position away from the clamping direction, that is, the V-shaped clamp 34 maintains a certain distance from the compressor housing and is in a loose state, avoiding contact and collision.

[0036] As the reciprocating drive chain 20 drives the base 31 to move along the first guide rail 50, it also synchronously drives the follower 32 to advance in the conveying direction. When the follower 32 continues to move, the guide pulley 33 thereon will gradually contact the first guide rail 50. At this time, the first guide rail 50 will apply a force to the guide pulley 33 that is opposite to the clamping direction of the follower 32. This force will gradually compress the return spring 35 and prompt the follower 32 to move along the clamping direction. As the follower 32 moves along the clamping direction, the V-shaped clamp 34 installed thereon also moves inward. The two clamping ports on both sides gradually approach and firmly clamp the compressor housing. Once the compressor housing is firmly clamped, the reciprocating drive chain 20 can drive the clamp assembly 30 and the compressor housing to move together and move them in mid-air to the work station that needs to be processed, such as deburring, machining and other processes.

[0037] After completing a specific process, the reciprocating drive chain 20 continues to drive the base 31 to move until the guide pulley 33 is free from the constraint of the first guide rail 50. At this time, the return spring 35 that loses the external force will be quickly released, pushing the follower 32 to slide in the direction away from the clamping. The movement of the follower 32 will directly cause the V-shaped clamp 34 to loosen the compressor housing. Finally, the compressor housing continues to move under the drive of the belt conveyor 10, completing the unloading process and entering the next link, repeating the cycle to realize continuous and automatic transportation of the compressor housing.

[0038] In this embodiment, a roller is provided at the end of the V-shaped clamp 34 and is made of rubber. The rubber roller has a certain elasticity and can better adapt to the slight unevenness of the compressor housing surface, reducing the wear and scratches that may be caused by hard contact. The cushioning properties of rubber can also absorb some of the impact force, further protecting the housing surface.

[0039] In some embodiments, as Figure 1 、 Figure 5 As shown, the links 21 of the reciprocating drive chain 20 are fixed with a horizontally outwardly extending connecting plate 22. The connecting plate 22 is provided with at least two threaded holes along the length of the link 21. The upper surface of the base 31 is provided with threaded holes as the connecting structure. The coupling member 40 is threadedly connected and fixed to the connecting plate 22 and the base 31 respectively by bolts. During the specific connection, the coupling member 40 passes through its own through-holes and is threadedly connected to the threaded holes in the connecting plate 22 and the base 31, thereby firmly fixing the clamp assembly 30 to the reciprocating drive chain 20, ensuring that the V-shaped clamp 34 can accurately contact the compressor housing and achieve an optimal clamping effect.

[0040] In some embodiments, as Figure 1 、 Figure 3 、 Figure 4 As shown, the connecting member 40 includes a first arm 41 fixedly connected to the chain link 21 of the reciprocating drive chain 20, and a second arm 42 fixedly connected to the connecting structure of the base 31; the first arm 41 and the second arm 42 are arranged in parallel and opposite to each other to form a clearance space 90; a second guide rail 51 extending along the conveying direction is provided below the reciprocating drive chain 20, and the second guide rail 51 passes through each of the clearance spaces 90; the end of the first arm 41 is pivotally connected to a guide wheel 43 in contact with the upper rail surface of the second guide rail 51.

[0041] This structural design allows the second guide rail 51 to precisely pass through the clearance space 90 formed between the first arm 41 and the second arm 42 of the link 40 when the chuck assembly 30, along with the reciprocating drive chain 20, reaches the second half of its travel. Simultaneously, a cylindrical guide wheel 43 is pivotally connected to the end of the first arm 41 away from the chain link 21, via a bearing or other means. The outer circumference of the guide wheel 43 maintains rolling contact with the upper surface of the second guide rail 51.

[0042] During specific operation, when the chuck assembly 30 moves downward along with the reciprocating drive chain 20, the guide wheel 43 will gradually contact the upper surface of the second guide rail 51, so that the second guide rail 51 provides support for the guide wheel 43 and transmits the support force to the chuck assembly 30 through the first arm 41, thereby bearing part of the weight of the chuck assembly 30 and the compressor housing it clamps, effectively reducing the load of the reciprocating drive chain 20 and reducing the wear and energy consumption of the drive chain. In addition, the cooperation between the second guide rail 51 and the guide wheel 43 also provides additional guidance for the movement of the chuck assembly 30, limiting its shaking in the vertical direction, making the movement of the chuck assembly 30 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. Especially when clamping a heavier compressor housing, this support effect is more significant, which can effectively prevent the drive chain from shaking or deforming due to excessive load, thereby extending the service life of the equipment.

[0043] In some embodiments, as Figure 1 As shown, a third guide rail 52 extending in the conveying direction is provided above the reciprocating drive chain 20; when the reciprocating drive chain 20 drives the chuck assembly 30 to move above it, the guide wheel 43 contacts the upper rail surface of the third guide rail 52. Similar to the second guide rail 51, the third guide rail 52 also primarily serves a supporting and guiding role. That is, when the chuck assembly 30 moves above the reciprocating drive chain 20, its own weight is transferred to the third guide rail 52 via the guide wheel 43, and the third guide rail 52 bears this weight, thereby further reducing the pulling load of the reciprocating drive chain 20, making the force on the drive chain more uniform throughout the entire cycle and avoiding the situation where the force is excessive in some areas.

[0044] In some embodiments, as Figure 2 、 Figure 3 、 Figure 4 As shown, it also includes an L-shaped connecting plate 60 and at least two threaded columns 61. The V-shaped clamp 34 is detachably fixed to the first side plate of the L-shaped connecting plate 60; the threaded column 61 is arranged on the second side plate of the L-shaped connecting plate 60; the follower 32 is provided with a threaded hole adapted to the threaded column 61, and the threaded column 61 is connected to the follower 32 through the threaded hole.

[0045] In specific implementation, by rotating the threaded column 61 on the L-shaped connecting plate 60, 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 61 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 61 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.

[0046] In some embodiments, as Figure 3 、 Figure 4 As shown, the follower 32 is provided with a wheel frame 70, which is provided with a vertical wheel axle. The guide pulley 33 is coaxially fixed to the wheel axle. The guide pulley 33 is a waist drum wheel. The shape of the waist drum wheel provides a self-centering function. When the guide pulley 33 moves on the first guide rail 50, even if the installation position of the first guide rail 50 deviates slightly, the waist drum wheel can automatically adjust due to its special curved surface shape, ensuring that the guide pulley 33 always remains in the correct guide rail position, reducing movement deviation caused by guide rail installation errors.

[0047] In some embodiments, as Figure 3 、 Figure 6 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.

[0048] The compressor casing clamping and transporting mechanism provided in this embodiment, through its adjustable clamping component design, greatly improves the versatility of tooling, enabling it to adapt to compressor casings of different sizes and shapes without the need for frequent tooling replacement, thereby significantly reducing production costs and shortening the production preparation cycle. At the same time, the relatively movable clamping unit ensures the stability and reliability of the clamping, avoids slipping, deviation, and damage during transport, and improves transport safety. In addition, the mechanism uses a cyclic and re-circulating drive chain and a guide mechanism to work together to achieve automated clamping and transport of the compressor casing, greatly improving transport efficiency, reducing labor intensity, and improving production continuity.
