Description

Technical Field

[0001] This invention relates to the field of auxiliary tooling technology, and more specifically, to an auxiliary tooling for assembling a final air compressor. Background Technology

[0002] The vehicle assembly typically includes small parts with pre-attached structures, which can be pre-attached to the assembly base before assembly. Operators can use both hands to pick up and tighten the tools to complete the fastening work. However, the chassis air compressor is a heavy component, and due to its own structural limitations, it cannot be equipped with a pre-attached structure. At present, there are no special auxiliary tools for assembly, and the entire assembly operation relies on operators to manually lift the air compressor to complete the assembly work.

[0003] There is currently no good solution to the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide an auxiliary tooling for assembling a final air compressor, in order to solve the technical problems of existing chassis air compressor assemblies that lack tooling support and can only be manually lifted, resulting in high labor intensity for workers, poor lifting stability, inconvenient assembly alignment, and operators being unable to use tightening tools independently with their hands free.

[0005] To achieve the above objectives, according to one aspect of the present invention, an auxiliary tooling for assembling an air compressor is provided, comprising: a lifting part having a support assembly having a conformal support space for placing different types of air compressors, the lifting part being detachably connected to the air compressor, the support assembly having a lifting position that cooperates with the air compressor, and a separation position that is separate from the air compressor; and a support portion located below the lifting part and connected to the lifting part, with the support assemblies spaced apart from each other.

[0006] Furthermore, the auxiliary tooling for assembling the air compressor also includes: a moving component, part of which is connected to the support, and the moving component is spaced apart from the lifting component; wherein, when the lifting component is in the lifting position, controlling the moving component can cause the support to drive the lifting component and the air compressor to move from the initial position to the target position.

[0007] Furthermore, the lifting part also includes: an adjustment component located below the support component, the adjustment component having a lead screw, one end of the lead screw being connected to the support component, the adjustment component being connected to the support part, and a portion of the adjustment component being movable relative to the support part, the lead screw being controlled to position the support component in the lifting position or the disengaged position.

[0008] Furthermore, the adjustment assembly also includes: an adjustment plate connected to the support, and a lead screw movably connected to the threaded hole of the adjustment plate; and a drive assembly connected to the other end of the lead screw, with the drive assembly and the adjustment plate spaced apart.

[0009] Furthermore, the adjustment assembly also includes: a limiting sleeve, which is connected to the adjustment plate, and multiple limiting sleeves are arranged in an array on the adjustment plate; and a limiting rod, one end of which is connected to the adjustment plate and extends along the axis of the lead screw, and multiple limiting rods are arranged in a one-to-one correspondence with the limiting sleeves, with each limiting rod being movably connected to its corresponding limiting sleeve.

[0010] Furthermore, the support assembly includes: a support plate, one side of which is connected to one end of a limiting rod and one end of a lead screw, and the support plate has a first conformal support space; a first support wall structure, located above the support plate and connected to the support plate, and having a second conformal support space; and a second support wall structure, located at one end of the support plate and connected to the support plate, and having a third conformal support space; wherein the first conformal support space, the second conformal support space, and the third conformal support space enclose a conformal support space.

[0011] Furthermore, the first conformal support space is arranged adjacent to one end of the support plate.

[0012] Furthermore, the first support structure includes: support blocks, at least two support blocks are arranged symmetrically about the geometric center line of the first conformal support space, and each support block has a second conformal support space.

[0013] Furthermore, the second support structure includes: a support plate, at least two support plates are included, the two support plates are symmetrically arranged about the geometric center line of the first conformal support space, and each support plate has a third conformal support space.

[0014] Furthermore, the support includes: a connecting component, one end of which is connected to one side of the adjusting plate, and the connecting component and the support component are spaced apart; and a base plate, which is connected to the other end of the connecting component, and the base plate and the adjusting plate are spaced apart.

[0015] By applying the technical solution of this invention, the supporting part below supports the lifting part. The lifting part relies on the conformal support space of the supporting component to place different models of air compressors. The lifting part can switch between the lifting position and the detached position and can be detachably matched with the air compressor. The tooling replaces manual lifting of the air compressor, reducing the worker's load, ensuring the stable assembly and positioning of the air compressor, and freeing the operator's hands to hold and tighten the tools, improving assembly accuracy, assembly efficiency and work safety. This solves the technical problems of existing chassis air compressor assembly without tooling support, which can only be manually lifted, resulting in high labor intensity for workers, poor lifting stability, inconvenient assembly alignment, and the inability of operators to use tightening tools independently.

[0028] In the standardized assembly system of the automotive final assembly line, the vast majority of small assembly parts adopt a modular pre-attached structure design. This structure design is one of the core measures for optimizing the final assembly process, improving ergonomics, and enhancing quality and efficiency. The pre-attached structure of conventional small parts features strong adaptability, convenient operation, and stable positioning. In the actual assembly process, operators can pre-fix the small parts to be assembled to designated positions on the body, chassis, and corresponding assembly base using pre-set clips, attachment points, and positioning slots before the formal tightening process. After pre-attaching, the parts can maintain their position autonomously without continuous manual support. This allows operators to completely free their hands, simultaneously using torque wrenches, ratchet wrenches, electric tightening machines, and other professional tightening tools to carry out standardized, high-precision bolt tightening and locking assembly operations. This standardized pre-attached assembly mode greatly optimizes the final assembly process, reduces the difficulty of manual operation, and adapts to the continuous and rhythmic production requirements of assembly lines, making it the mainstream high-efficiency assembly method in the final assembly workshop.

[0029] However, in the chassis assembly section, there are many heavy, bulky, and structurally unique core components. Due to multiple objective factors such as the original product structural design, chassis space layout, and component function, these heavy components cannot be designed or equipped with pre-mounted positioning structures, making it impossible to achieve autonomous pre-fixation before assembly. Currently, the workshop lacks dedicated lifting aids, positioning fixtures, and assistive equipment for these heavy chassis components without pre-mounted structures. The entire process relies entirely on manual lifting, alignment, support, and assembly by workers. During the operation, employees must continuously lift the heavy objects with their arms and shoulders, maintaining the components horizontally and accurately, and completing a series of assembly processes such as bolt alignment and step-by-step tightening while under physical load. Compared to the standardized two-handed assembly of conventional components with pre-mounted structures, this purely manual lifting assembly mode has many drawbacks, significantly impacting the operational safety, product quality, production efficiency, and ergonomics of the final assembly line. The specific problems and their profound impacts can be detailed in four dimensions.

[0030] First, the manual lifting and assembly method results in extremely high labor intensity for employees, leading to significant work fatigue and increasing the risk of occupational injuries with prolonged operation. This severely impacts the working condition and continuous work capacity of frontline workers. The components of the final assembly chassis without pre-mounted structures are mostly core components of the chassis suspension, braking, and transmission systems. The weight of a single part generally far exceeds that of conventional assembly parts, with some heavy parts weighing tens of kilograms. Furthermore, the irregular shapes and dispersed stress points of these parts make it impossible to distribute force evenly during manual lifting. In the continuous, rhythmic production mode of the assembly line, employees must maintain precise alignment by lifting heavy parts throughout a fixed timeframe. From part retrieval and alignment to initial bolting and step-by-step tightening, the entire process lasts several minutes without any reduction in load or interruption.

[0031] Unlike the relaxed operation mode of pre-attached parts assembly, where pre-attached structures allow parts to be autonomously positioned and fixed, requiring only light tools and minimal physical exertion from employees, manual lifting requires sustained tension and effort from muscles in the upper limbs, back, shoulders, and neck to counteract the weight of the parts and maintain their position. Even short periods of this can lead to muscle soreness and stiffness. With continuous daily batch production, the repetitive, high-intensity lifting motions cause accumulated fatigue that cannot be effectively alleviated. Short-term fatigue can result in weakness and decreased concentration, while long-term, high-frequency heavy lifting can lead to occupational problems such as lumbar muscle strain, shoulder injuries, chronic arm muscle fatigue, and joint pain. Furthermore, accumulated fatigue directly reduces the stability of continuous work, leading to a decline in employee performance and motivation. This not only affects the quality of work at individual workstations but also reduces their productivity, making it difficult to match the standard production line pace. It also increases the management pressure of shift rotation and replacement, posing a significant challenge to workshop ergonomics optimization and employee occupational health protection.

[0032] Secondly, purely manual assembly makes it difficult to guarantee assembly accuracy and product quality stability, easily leading to various assembly defects, potential product quality risks, and affecting the overall reliability of the vehicle chassis assembly. As the core system for vehicle driving, braking, and load-bearing, the automotive chassis requires extremely high standards for component assembly accuracy, tightening torque, sealing performance, and fit. Even minor assembly deviations can cause vehicle malfunctions, making it crucial for product safety and stability. When assembling parts with pre-mounted structures, zero-deviation precise alignment can be achieved using the pre-set positioning structure. Parts do not wobble or shift, and employees can steadily operate the tightening tools, strictly adhering to the process torque standards to complete the tightening. Assembly consistency and accuracy are fully guaranteed, resulting in extremely high batch product quality stability.

[0033] Manual lifting of heavy components without pre-attached supports relies entirely on human touch and experience to control component position, introducing significant uncertainty. During lifting, factors such as component weight, arm fatigue, slight vibrations from the assembly line, and limitations in operating angles cause components to easily wobble, shift, or tilt, making precise alignment and tight fit difficult. In the core processes of bolt insertion and step-by-step tightening, to ensure components don't fall off or shift, employees must continuously lift and stabilize the component while simultaneously operating tools with one hand for tightening. The stability and accuracy of single-handed operation are far lower than standardized two-handed operation. Even slight displacement during tightening can lead to misaligned bolt holes and thread misalignment, resulting in issues like thread stripping, mis-threading, and inadequate bolt tightening. Furthermore, for chassis components with gaskets and sealing surfaces, manual lifting and shaking can cause loose sealing surfaces and uneven stress, leading to sealing gap deviations and potentially causing oil, water, or air leaks.

[0034] In addition, individual differences exist among employees in terms of height, arm length, operating experience, and physical condition. Even for the same employee, the stability and alignment accuracy of lifting can fluctuate due to fatigue at different work hours, leading to extremely poor assembly consistency in batches of products. This results in issues such as inconsistent assembly tightness, varying fit, and excessive torque deviation. While some of these quality defects caused by manual assembly deviations can be identified and rectified through off-line quality inspection, some latent defects are difficult to detect in a timely manner. Once these defects reach subsequent processes and the end market, they can cause after-sales problems such as abnormal noises in the vehicle, loose chassis, and seal failure, significantly reducing product quality and market reputation, while also increasing rework and repair costs, as well as quality claim costs.

[0035] Third, the assembly mode involving purely manual lifting poses extremely high safety and occupational health risks. Handling heavy objects without any auxiliary equipment or protective gear is highly prone to accidents and is a key hidden danger point for workshop safety management. The final assembly workshop operates on a continuous assembly line, with compact workspaces, dense personnel operations, and frequent equipment operation; therefore, safety is the core bottom line of production management. The assembly of parts with pre-attached structures involves no risk of heavy lifting throughout the process, and the standardized and safe operating procedures result in virtually no safety hazards. However, manually lifting heavy chassis parts relies entirely on the human body for support, without any tooling or auxiliary equipment for assistance or protection, posing multiple safety risks and occupational health hazards.

[0036] From an occupational health perspective, prolonged single-person lifting of heavy parts continuously puts pressure and strain on the lower back, shoulders, neck, and arm joints, exceeding the normal load-bearing capacity of the limbs. Long-term, high-frequency, and high-intensity repetitive lifting movements can lead to occupational diseases such as muscle strain, ligament damage, lumbar disc injury, and frozen shoulder, seriously harming employees' health. This not only affects individual employees' occupational health but also increases the management pressure on companies in terms of work injury control and occupational health protection. From a field safety perspective, during manual lifting, factors such as the heavy weight of the parts, their smooth surfaces, uneven force, sweaty hands, and limb fatigue can easily cause parts to slip, fall, or shift. If a heavy part accidentally falls, it can directly injure the worker's hands, arms, and torso, and in severe cases, even cause fractures or serious injuries.

[0037] Meanwhile, in the dynamic operation scenario of an assembly line, employees need to exert high-intensity force to keep parts stable in order to keep up with the production pace and ensure precise assembly alignment. Their limbs are in a state of tension and overload for a long time, which reduces their reaction sensitivity and emergency response capabilities. When faced with sudden situations such as abnormal movement of assembly line equipment or movement of surrounding personnel, they are unable to avoid risks in time, further amplifying the operational safety hazards. In addition, falling parts can not only cause personal injury accidents, but also cause parts to be deformed, damaged in appearance, and lose precision, resulting in scrapped parts, increasing production costs and losses. They may even collide with workstation equipment and tooling fixtures, causing equipment failure and affecting the normal operation of the production line.

[0038] Finally, the cumbersome and redundant manual lifting assembly process directly leads to low workstation efficiency, making it unable to adapt to the standardized rhythm of the assembly line and hindering overall capacity improvement. Modern automotive final assembly lines have strict standardized requirements for workstation operation time and single-piece operation rhythm. Efficient connection and synchronous operation of each workstation are the core to ensure overall capacity. The conventional assembly process of parts with pre-mounted structures is simple and efficient. After the parts are pre-mounted and positioned, employees can focus on the fastening operation. The process is smooth and streamlined, with no unnecessary steps. The single-piece operation time is controllable and stable, perfectly matching the rhythm requirements of the production line.

[0039] In contrast, manual lifting and assembly of heavy parts without pre-attached supports involves numerous redundant steps, significantly reducing efficiency. The process cannot achieve simultaneous positioning and tightening; the work must be broken down into steps: first, both hands must be used to lift the part for precise alignment and initial positioning, maintaining limb stability throughout; after alignment, one hand must continuously support and secure the part while the other hand grabs and adjusts the tightening tool, gradually tightening the bolts; in multi-bolt assembly processes, the lifting force and part position must be repeatedly adjusted to avoid part misalignment during tightening, with some points even requiring repeated alignment and secondary tightening. This step-by-step operation mode of "lifting and positioning first, then tightening with other hands, and repeated adjustments" is far more cumbersome and time-consuming than the standardized operation of simultaneous tightening with both hands, resulting in a significantly longer single-piece operation time.

[0040] In continuous mass production, low efficiency at a single workstation directly slows down the entire production line, leading to workstation congestion, waiting times, and unbalanced production cycles. To compensate for this, it's often necessary to reduce employee rest time, accelerate work pace, and increase manpower, further intensifying employee workload and creating a vicious cycle of "high-intensity work, low-efficiency output, and high fatigue accumulation." Simultaneously, the uncertainty of work hours makes standardized control of workstation capacity impossible, increasing the difficulty of implementing production plans and easily resulting in undercapacity and delayed delivery. This severely restricts overall workshop production efficiency and capacity improvement, impacting the standardization, refinement, and efficiency of production line management.

[0041] In summary, the purely manual lifting assembly mode for heavy chassis parts without pre-attached structures presents four major problems compared to standardized pre-attached assembly: high labor intensity, poor quality stability, significant safety hazards, and low operational efficiency. This mode relies entirely on manual load-bearing, violating ergonomic principles and failing to meet the demands of modern assembly lines for improved quality, efficiency, and safety. It not only harms employee occupational health, creates safety hazards, and affects core product quality, but also severely hinders efficient production line operation and the implementation of standardized management. Therefore, it is urgently necessary to transform the existing operation mode by adding specialized lifting aids, customizing positioning fixtures, introducing power-assisted equipment, and optimizing the process structure. This will eliminate the drawbacks of manual lifting and achieve standardized, safe, efficient, and precise assembly of heavy chassis parts, comprehensively improving the production quality and efficiency of the final assembly workshop.

[0042] According to one aspect of the embodiments of this application, an auxiliary tooling for assembling a final air compressor is provided.

[0043] Specifically, such as Figure 1As shown, an auxiliary tooling for assembling an air compressor includes: a lifting part 20, which has a support assembly having a conformal support space for placing different types of air compressors; the lifting part 20 is detachably connected to the air compressor; the support assembly has a lifting position that cooperates with the air compressor; and a separation position that separates from the air compressor; a support part 10 located below the lifting part 20 and connected to the lifting part 20; and support assemblies spaced apart from each other.

[0044] By applying the technical solution of this invention, a stable tooling support body is formed by the lower support part 10 supporting the lifting part 20, and the air compressor is reliably positioned and assisted in assembly by relying on the support components of the lifting part 20. This tooling replaces the traditional manual lifting operation mode with a purely mechanical structure, fundamentally changing the assembly method of the chassis air compressor and effectively solving multiple technical problems existing in the current assembly process.

[0045] The support components are designed with conformal support space, which can precisely fit and stably support different models of air compressors, eliminating the need for customized tooling for a single model and significantly improving the applicability and reusability of the tooling. At the same time, the lifting part 20 can flexibly switch between the lifting position and the detachable position, and adopts a detachable engagement method with the air compressor. This facilitates quick loading and positioning before assembly, and also facilitates smooth removal of the tooling after assembly, greatly simplifying the operation process and reducing the complexity of tooling switching and operation.

[0046] This fixture fully supports the weight of the air compressor, completely eliminating the operator's burden and preventing occupational health problems such as muscle fatigue and joint damage caused by prolonged lifting of heavy parts. At the same time, the fixture's rigid support completely avoids the safety hazard of parts accidentally falling and injuring personnel during manual lifting, significantly improving the working environment and reducing the pressure on workshop safety management.

[0047] The stable support of the tooling ensures that the air compressor is firmly positioned and free from shaking or displacement throughout the assembly process, completely solving problems such as alignment deviation, misaligned threads, and poor sealing that occur when manually lifting the compressor. This significantly improves assembly accuracy and product quality consistency. More importantly, operators no longer need to support parts with one hand; they can use both hands simultaneously to hold tightening tools for standardized fastening operations, effectively shortening the assembly time for a single part and ensuring the stable operation of the production line.

[0048] In summary, this embodiment effectively solves a series of technical problems in the existing chassis air compressor assembly, such as the lack of dedicated tooling support, reliance on manual lifting, high labor intensity, poor lifting stability, inconvenient assembly alignment, and the inability of operators to independently operate tightening tools with both hands. It comprehensively improves the work quality, production efficiency, and safety level of the chassis assembly process.

[0049] Furthermore, the auxiliary tooling for assembling the air compressor also includes: a moving component 50, part of which is connected to the support part 10, and the moving component 50 is spaced apart from the lifting part 20; wherein, when the lifting part 20 is in the lifting position, controlling the moving component 50 can cause the support part 10 to drive the lifting part 20 and the air compressor to move from the initial position to the target position.

[0050] In this embodiment, the movable component 50 added to the auxiliary tooling for assembling the air compressor is securely connected to the support part 10 and maintained at a reasonable distance from the lifting part 20. When the lifting part 20 is in a stable lifting position and reliably supports the air compressor, only the movable component 50 needs to be controlled to allow the support part 10 to drive the lifting part 20 and the supported heavy air compressor to move smoothly from the initial material handling position to the target position for chassis assembly. This completely replaces the traditional manual handling or multi-person lifting method. This design not only significantly reduces the labor intensity of operators and avoids occupational health problems such as back muscle strain and joint damage caused by long-distance handling of heavy parts, but also fundamentally eliminates the safety risks of air compressor collisions and deformations, damage to internal precision components, and injuries caused by falling parts due to unstable grip and physical exhaustion during manual handling.

[0051] Meanwhile, the rigid transmission structure of the moving component 50 ensures the air compressor remains stable and free from violent shaking throughout the entire movement process, effectively protecting the internal rotor, valve plates, and other delicate and vulnerable components from vibration damage. It also allows for precise positioning at the preset assembly location, significantly reducing subsequent assembly alignment adjustment time. Furthermore, the application of this moving component 50 enables a single operator to independently complete the entire process of air compressor material handling, transfer, and assembly without additional personnel, effectively saving labor costs, significantly shortening auxiliary work time between workstations, and improving overall assembly efficiency. This better adapts to the high-speed, high-frequency continuous operation requirements of the final assembly line.

[0052] like Figure 2 As shown, the lifting part 20 also includes an adjustment component located below the support component. The adjustment component has a lead screw 205, one end of which is connected to the support component. The adjustment component is connected to the support part 10. Part of the adjustment component can move relative to the support part 10. By controlling the lead screw 205, the support component can be positioned in the lifting position or the detached position.

[0053] In this embodiment, the adjustment component added to the lifting part 20 is located below the support component and is securely connected to the support part 10. The adjustment component is connected to the support component at one end via a lead screw 205, and part of its structure can move relative to the support part 10. By controlling the lead screw 205, the support component can be precisely driven to smoothly switch between the lifting position and the separation position. This lead screw-driven adjustment structure features high transmission accuracy, good self-locking performance, and smooth operation. It can achieve stepless and precise adjustment of the height of the support component, accurately adapting to the different assembly height requirements of air compressors for different vehicle chassis. It can meet the requirements of multi-vehicle co-production without changing tooling, significantly improving the versatility and reusability of tooling.

[0054] Meanwhile, the self-locking characteristic of the lead screw 205 ensures that the support assembly remains stable and reliable in the lifting position, preventing slippage or displacement due to the air compressor's own weight or external forces during assembly. This provides reliable rigid support for air compressor assembly, effectively avoiding height deviation issues during manual alignment and significantly improving assembly alignment accuracy and product quality consistency. Furthermore, the lifting and lowering of the support assembly can be quickly completed by controlling the lead screw 205, eliminating the need for manual lifting or height adjustment, further reducing the operator's workload. After assembly, the support assembly can be easily lowered to the separation position, allowing the tooling to smoothly exit from under the chassis without scratching the assembled air compressor and surrounding components. The operation process is simple and efficient, effectively shortening the assembly time for a single piece and better adapting to the rhythmic operation requirements of the final assembly line.

[0055] Furthermore, the adjustment assembly also includes: an adjustment plate 201, which is connected to the support part 10, and a lead screw 205 is movably connected to the threaded hole of the adjustment plate 201; and a drive assembly, which is connected to the other end of the lead screw 205, and is spaced apart from the adjustment plate 201.

[0056] In this embodiment, the adjustment component is securely connected to the support part 10 via the adjustment plate 201 to form a reliable installation reference. The lead screw 205 is movably connected to the threaded hole of the adjustment plate 201 to achieve precise helical transmission. The drive component is fixedly connected to the other end of the lead screw 205 and maintains a reasonable distance from the adjustment plate 201. This structural design allows the adjustment plate 201 to provide stable radial support and axial limit for the lead screw 205, effectively preventing bending deformation or radial swaying of the lead screw 205 during transmission, significantly improving the load-bearing capacity and operational stability of the adjustment component, and reliably supporting air compressors of different weights. At the same time, the transmission between the lead screw 205 and the threaded hole of the adjustment plate 201 features high transmission accuracy, good self-locking performance, and smooth, shock-free operation. Combined with the power input provided by the drive component, the height adjustment of the support component can be quickly completed without manual force from the operator, greatly reducing the difficulty of operation and labor intensity, and achieving millimeter-level precise height control to accurately adapt to the assembly height requirements of air compressors on different vehicle chassis.

[0057] In addition, the spacing between the drive assembly and the adjustment plate 201 effectively avoids interference between the drive assembly and the adjustment plate 201 during operation, while reserving sufficient maintenance and repair space to facilitate daily maintenance and troubleshooting of the drive assembly and the lead screw 205 transmission structure. The overall structure is compact and reasonable, and the installation and maintenance are convenient, which can effectively improve the service life and operational reliability of the tooling and better meet the needs of long-term continuous operation of the final assembly production line.

[0058] In this embodiment, the adjustment assembly further includes: a limiting sleeve 202, which is connected to the adjustment plate 201. Multiple limiting sleeves 202 are arrayed on the adjustment plate 201. A limiting rod 203 is also included, with one end connected to the adjustment plate 201. The limiting rod 203 extends along the axis of the lead screw 205. Multiple limiting rods 203 are also included, each corresponding to a limiting sleeve 202. Each limiting rod 203 is movably connected to its corresponding limiting sleeve 202.

[0059] In this embodiment, multiple limiting sleeves 202 arrays added to the adjustment component are arranged on the adjustment plate 201 and securely connected thereto. Multiple limiting rods 203 extend along the axis of the lead screw 205 and are connected at one end to the support component. Each limiting rod 203 is movably connected to its corresponding limiting sleeve 202. This array-type limiting sleeve 202 and limiting rod 203 cooperation structure can provide precise linear guidance for the lifting and lowering movement of the support component, effectively preventing the support component from circumferentially rotating or laterally shifting during the lifting and lowering process driven by the lead screw 205, ensuring that the support component always maintains a horizontal posture and lifts and lowers smoothly, greatly improving the straightness and stability of height adjustment.

[0060] Meanwhile, the multi-point support structure formed by multiple limiting rods 203 and limiting sleeves 202 can effectively share the radial load and overturning moment borne by the lead screw 205, significantly enhancing the overall load-bearing capacity and anti-eccentric load performance of the adjustment assembly. Even when supporting air compressors with large weight or slight center of gravity shift, it can ensure that the support assembly will not tilt or deform, providing continuous and reliable rigid support for air compressor assembly. In addition, the precise cooperation between the limiting rods 203 and the limiting sleeves 202 can further improve the accuracy of height adjustment, avoid assembly alignment deviations caused by support assembly sway, improve assembly quality consistency, and effectively protect the lead screw 205 from radial force damage, extend the service life of the lead screw 205, reduce tooling failure rate and maintenance costs. Moreover, this structure operates smoothly without jamming, and in conjunction with the transmission of the lead screw 205, it can achieve rapid and stable lifting and lowering of the support assembly, making operation convenient and efficient, and better adapting to the rhythmic continuous operation requirements of the final assembly line.

[0061] Further, the support assembly includes: a support plate 204, one side of which is connected to one end of a limiting rod 203 and one end of a lead screw 205, and the support plate 204 has a first conformal support space 208; a first support wall structure, located above the support plate 204 and connected to the support plate 204, and having a second conformal support space; and a second support wall structure, located at one end of the support plate 204 and connected to the support plate 204, and having a third conformal support space; wherein the first conformal support space 208, the second conformal support space, and the third conformal support space enclose a conformal support space.

[0062] In this embodiment, one side of the support plate 204 of the support assembly is securely connected to one end of the limiting rod 203 and one end of the lead screw 205, respectively. The support plate 204 has a first conformal support space 208. The first support wall structure is located above the support plate 204 and is fixedly connected to it, and has a second conformal support space. The second support wall structure is located at one end of the support plate 204 and is fixedly connected to it, and has a third conformal support space. The first conformal support space 208, the second conformal support space and the third conformal support space together form an overall conformal support space that precisely matches the shape of the air compressor.

[0063] This multi-dimensional, split-type conformal support structure can simultaneously conform to the bottom, sides, and ends of the air compressor, achieving uniform force support at multiple points. This effectively avoids deformation or tilting of the air compressor casing caused by concentrated force at a single point. Furthermore, the combined design of the three conformal support spaces can flexibly adapt to the shape differences of different air compressor models, meeting the needs of multi-model co-production without replacing the core support structure, significantly improving the versatility and reusability of the tooling. The rigid integrated connection of the support plate 204 with the limiting rod 203 and lead screw 205 ensures the stability of the support foundation. Combined with the horizontal limiting effect of the first and second support wall structures, it completely eliminates lateral displacement or circumferential rotation of the air compressor during assembly, greatly improving assembly alignment accuracy and the stability of the fastening process. This effectively avoids assembly defects such as mis-threading and poor sealing. Moreover, the overall structure is simple and compact, with low manufacturing costs and convenient maintenance, enabling long-term stable adaptation to the high-intensity continuous operation requirements of the final assembly line.

[0064] Specifically, the first conformal support space 208 is disposed adjacent to one end of the support plate 204. In this embodiment, the first conformal support space 208 is disposed adjacent to one end of the support plate 204. This arrangement allows the first conformal support space 208 to accurately fit the corresponding boss, interface or irregular contour at the bottom of the air compressor, providing a clear end positioning reference for the air compressor. Together with the second support wall structure at the other end of the support plate 204, it forms a bidirectional axial limit, completely eliminating the sliding displacement of the air compressor along the length direction of the support plate 204 during the assembly process.

[0065] In an exemplary embodiment, the first support structure includes: support blocks 206, at least two support blocks 206 are symmetrically arranged about the geometric center line of the first conformal support space 208, and each support block 206 has a second conformal support space.

[0066] In this embodiment, the first support structure consists of at least two support blocks 206. The two support blocks 206 are symmetrically arranged about the geometric center line of the first conformal support space 208, and each support block 206 is respectively machined with a second conformal support space that matches the side profile of the air compressor. This symmetrical multi-point support layout can make the support force on both sides of the air compressor completely balanced, effectively avoiding the tilting and displacement of the air compressor caused by uneven force on one side, and greatly improving the stability and reliability of lateral support.

[0067] Meanwhile, the symmetrically distributed support blocks 206 can provide bidirectional lateral restraint for the air compressor, completely eliminating lateral movement or circumferential rotation of the air compressor during assembly and fastening, ensuring that the bolt holes are always precisely aligned, and effectively avoiding assembly defects such as misaligned threads and poor sealing surface fit. The independently set second conformal support space of each support block 206 can precisely fit the irregular protrusions, reinforcing ribs and other structures on the side of the air compressor, achieving surface contact support, dispersing local concentrated loads, and preventing deformation and damage to the air compressor housing due to excessive force at a single point. Moreover, the conformal contour of a single support block 206 can be quickly adapted to the side structure differences of different models of air compressors without the need to replace the entire support assembly, further improving the versatility of the tooling and reducing the modification cost. The overall structure is simple, reliable and easy to process, and can stably meet the high-intensity continuous operation requirements of the final assembly line for a long time.

[0068] In this embodiment, the second support structure includes: a support plate 207, at least two support plates 207 are included, the two support plates 207 are symmetrically arranged about the geometric center line of the first conformal support space 208, and each support plate 207 has a third conformal support space.

[0069] In this embodiment, the second support structure is composed of at least two support plates 207. The two support plates 207 are symmetrically arranged about the geometric center line of the first conformal support space 208. Each support plate 207 is respectively machined with a third conformal support space that precisely matches the end profile of the air compressor. This symmetrical end support layout ensures that the axial support force at both ends of the air compressor is completely balanced, effectively preventing the air compressor from tilting or shifting due to uneven end force, and significantly improving the stability and reliability of axial support. The third conformal support space of each support plate 207 can closely fit the flanges, interfaces, reinforcing ribs and other irregular structures at the ends of the air compressor, achieving large-area surface contact support, evenly distributing the end load, and preventing the air compressor casing from deforming or being damaged due to localized concentrated force. At the same time, it forms a reliable axial limit for the air compressor. Together with the first conformal support space 208 set adjacent to the ends, it can form a two-way axial constraint, completely eliminating the air compressor's movement and displacement along the length direction during assembly and fastening. Combined with the lateral limit formed by the support blocks 206 symmetrically set in the first support structure, a comprehensive three-dimensional positioning support system is constructed to ensure that the air compressor maintains a precise and stable posture throughout the entire assembly process, effectively avoiding assembly defects such as misaligned bolt holes, mis-threaded threads, and poor sealing surface fit.

[0070] In addition, the independently set support plate 207 can be individually adjusted to conform to the contour or replaced according to the end structure of different models of air compressors without the need for overall modification of the support components. This further improves the versatility and adaptability of the tooling, reduces the tooling modification cost for multi-model co-production, and has a simple and compact overall structure, low processing and manufacturing cost, and convenient installation and maintenance. It can meet the needs of high-intensity continuous operation of the final assembly line for a long time.

[0071] like Figure 3 As shown, the wall support plate 207 includes a first connecting segment 301, a first arc segment 302, a second arc segment 303, and a second connecting segment 304 connected in sequence. The second connecting segment 304 is connected to one end of the support plate 204, and the included angle between the first connecting segment 301 and the second connecting segment 304 is 131°.

[0072] In this embodiment, the support plate 207 of the second support structure adopts a segmented structural design consisting of a first connecting segment 301, a first arc segment 302, a second arc segment 303, and a second connecting segment 304 connected in sequence. The second connecting segment 304 is stably connected to one end of the support plate 204, and the included angle between the first connecting segment 301 and the second connecting segment 304 is optimized to 131°. This segmented arc transition structure can accurately match the irregular contours such as arc flanges and rounded corner transitions commonly found at the ends of air compressors, enabling the third conformal support space to achieve large-area close surface contact with the end of the air compressor, effectively dispersing the concentrated load at the end and preventing deformation or damage to the air compressor housing due to excessive local stress. The 131° included angle design, optimized through mechanical simulation and real vehicle adaptation, can perfectly match the end tilt angle of air compressors in mainstream vehicle chassis, ensuring that the direction of the support force always points towards the center of gravity area of ​​the air compressor, significantly reducing the overturning moment borne by the support components and further improving the stability and reliability of axial support.

[0073] Meanwhile, the angled support structure formed by the first connecting section 301 and the second connecting section 304 significantly enhances the structural rigidity and bending deformation resistance of the support plate 207 itself, enabling it to withstand the continuous load of the heavy air compressor for a long time without plastic deformation. In conjunction with another symmetrically arranged support plate 207, it can form a symmetrical and balanced bidirectional axial limit for the air compressor, completely eliminating the displacement of the air compressor along the length direction during assembly and fastening. Together with the first conformal support space 208 and the support block 206, it forms a stable three-dimensional positioning support system, effectively ensuring the alignment accuracy of bolt holes and the quality of sealing surface contact. Moreover, this segmented structure has a simple processing technology, low manufacturing cost, and easy dimensional accuracy control, enabling rapid mass production and meeting the high-intensity continuous operation requirements of the final assembly line.

[0074] like Figure 4As shown, the second conformal support space of the support block 206 includes: a first connecting surface 401, a second connecting surface 402 and a third connecting surface 403. The first connecting surface 401 is located near one end of the support block 206, the second connecting surface 402 is an arc-shaped surface, and the third connecting surface 403 is connected to the end face of the other end of the support block 206.

[0075] like Figure 5 As shown, the support part 10 includes: a connecting assembly, one end of which is connected to one side of the adjusting plate 201, and the connecting assembly is spaced apart from the support assembly; and a base plate 104, which is connected to the other end of the connecting assembly, and is spaced apart from the adjusting plate 201. The connecting assembly includes two support uprights 101 and a support crossbar 102. One end of the support uprights 101 is connected to the base plate 104, the two support uprights 101 are spaced apart, and the two support uprights 101 are connected by the support crossbar 102. The support part 10 also includes a counterweight 103, which is connected to the base plate 104 and is located below the support crossbar 102. The support unit 10 connects the base plate 104 and the adjustment plate 201 through a connecting assembly consisting of a support pole 101 and a support crossbar 102. The components are arranged at intervals in a regular structure, resulting in strong overall support stability. With the counterweight 103 located below the support crossbar 102 and connected to the base plate 104, the overall force can be effectively balanced, further reducing the probability of tilting or swaying of the device. The structure is reasonable, with excellent load-bearing and balance performance, and higher reliability in use.
