Description

Technical Field

[0001] This application relates to the field of assembly manufacturing technology, and in particular to an assembly tooling and assembly system. Background Technology

[0002] Existing spindle assembly solutions are primarily based on traditional mechanical assembly processes. In this approach, a marble platform is often used as a reference surface to ensure assembly accuracy and stability.

Auxiliary lifting devices are responsible for lifting and positioning heavy components, such as the spindle, ensuring its proper position during assembly.

[0003] While existing spindle assembly solutions can meet basic assembly requirements to some extent, component alignment still relies heavily on manual operation. In this process, workers need to rely on experience and visual judgment to precisely align the spindle and various components. However, due to the limitations of manual operation, the accuracy of this alignment method often falls short of the requirements of high-precision machining equipment. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0033] The spindle assembly directly affects the core performance of machining equipment. The spindle assembly process has a decisive impact on the equipment's machining accuracy, operating efficiency, and long-term stability. Spindle assembly typically includes multiple stages such as pre-tightening, positioning, assembly, and inspection. These stages are interconnected and together constitute a complete assembly process. During this process, strict control over assembly accuracy and sequence is necessary to ensure precise fit between the spindle and its related components, thereby achieving high-performance operation of the equipment.

[0034] Existing spindle assembly solutions are primarily based on traditional mechanical assembly processes. In this approach, a marble platform is often used as a reference surface to ensure assembly accuracy and stability. Simultaneously, leveling pads are widely used to adjust the height of assembled components to meet the demands of precision assembly. Auxiliary lifting devices are responsible for lifting and positioning heavy components, such as the spindle, ensuring its proper position during assembly.

[0035] While existing spindle assembly solutions can meet basic assembly requirements to some extent, component alignment still relies heavily on manual operation. In this process, workers need to rely on experience and visual judgment to precisely align the spindle and various components. However, due to the limitations of manual operation, the accuracy of this alignment method often falls short of the requirements of high-precision machining equipment.

[0036] In view of this, embodiments of this application disclose an assembly fixture and an assembly system. The assembly fixture can align the spindle with other parts to be installed along the axis when assembling the spindle, ensuring the assembly accuracy of the spindle and the parts to be installed and reducing errors caused by manual assembly.

[0037] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0038] Please see Figures 1 to 3 , Figure 1 A schematic diagram of the structure of the first type of spindle 200 and assembly fixture 100 provided in the embodiments of this application; Figure 2 One of the structural schematic diagrams of the second type of spindle 200 and assembly fixture 100 provided in the embodiments of this application; Figure 3This is the second structural schematic diagram of the second type of spindle 200 and assembly fixture 100 provided in the embodiments of this application. This application provides an assembly fixture 100 for assembling a spindle 200 and a component 300 to be installed. The fixture includes: a support 1, which includes a first support plate 11 for supporting the spindle 200. The first support plate 11 has a first mounting hole through which the spindle 200 can pass, allowing the first mounting hole to engage with the spindle 200; a movable frame 2, which is vertically movably mounted on the support 1 and located below the first support plate 11. The movable frame 2 carries the component 300 to be installed and includes a second mounting hole through which at least a portion of the component 300 can pass, allowing the second mounting hole to engage with the component 300. The second mounting hole and the first mounting hole are coaxially aligned vertically; and a driving member 3, which is mounted on the support 1 and drives the movable frame 2 to move vertically towards the first support plate 11, thereby causing the movable frame 2 to move the component 300 towards the spindle 200.

[0039] Specifically, bracket 1 provides a stable platform for the assembly process of spindle 200. Bracket 1 can withstand various forces and pressures generated during the assembly process, ensuring the smooth assembly of spindle 200. Through bracket 1, spindle 200 can be stably placed and positioned, avoiding assembly errors caused by shaking or instability.

[0040] Furthermore, the bracket 1 includes a first support plate 11 with a first mounting hole. The spindle 200 can pass through the first mounting hole, which precisely engages with and positions the spindle 200, ensuring its position and stability during assembly. This design allows the spindle 200 to be accurately aligned with the part 300 to be installed, laying the foundation for subsequent assembly work.

[0041] The movable frame 2 is movably mounted on the bracket 1 in the vertical direction and is located below the first support plate 11. The movable frame 2 can move in the vertical direction, so that the part to be installed 300 carried by the movable frame 2 can move closer to or away from the spindle 200 carried by the first support plate 11 above, so as to complete the assembly of the spindle 200.

[0042] The movable frame 2 is located below the first support plate 11, thereby reducing the space occupied by the assembly fixture 100, improving the flexibility and efficiency of the production site, and enabling more efficient assembly operations within a limited working area without the need to frequently move or adjust the layout of the assembly fixture 100.

[0043] The movable frame 2 is used to support the component 300 to be installed, ensuring the stability and accuracy of the component 300 during the installation process. A second mounting hole is provided on the movable frame 2, through which at least a portion of the component 300 can pass, allowing the second mounting hole to engage with the component 300, thereby positioning the component 300 and ensuring its relative position to the upper spindle 200.

[0044] During assembly, the drive unit 3 drives the movable frame 2 to move vertically towards the first support plate 11. Since the first mounting hole and the second mounting hole are coaxially aligned, when the movable frame 2 moves, it will cause the part to be installed 300 to move towards the spindle 200. This movement method not only ensures accurate docking between the part to be installed 300 and the spindle 200, but also improves the assembly efficiency of the spindle 200.

[0045] Furthermore, the mobility of the movable frame 2 allows it to accommodate components 300 of different sizes and shapes to be installed. By adjusting the height of the movable frame 2, various assembly tasks can be completed, thereby improving the versatility and flexibility of the assembly fixture 100.

[0046] It is understandable that during the assembly of the spindle 200, the spindle 200 is first placed on the first support plate 11 and positioned using the first mounting hole to ensure its fixed position. Then, the component to be installed 300 is placed on the movable frame 2 and positioned using the second mounting hole. Since the second mounting hole and the first mounting hole are coaxially aligned vertically, the positioned spindle 200 and component 300 can be arranged coaxially, resulting in higher installation accuracy.

[0047] Furthermore, after the spindle 200 and the part to be installed 300 are positioned, the control drive 3 drives the movable frame 2 to move vertically toward the first support plate 11, thereby bringing the part to be installed 300 closer to the spindle 200 and connecting the part to be installed 300 with the spindle 200.

[0048] Optionally, a preliminary connection can be made between the component to be installed 300 and the spindle 200, meaning that the component to be installed 300 and the spindle 200 are not fully locked together. After the preliminary connection, the coaxiality of the spindle 200 and the component to be installed 300 can be tested to ensure the assembly accuracy of the spindle 200. After adjusting the positions of the spindle 200 and the component to be installed 300 based on the coaxiality test results, the component to be installed 300 and the spindle 200 are finally connected, meaning that the component to be installed 300 and the spindle 200 are fully locked together, thus completing the assembly between the component to be installed 300 and the spindle 200.

[0049] At this point, the coaxiality of the assembled spindle 200 and the part to be installed 300 can be tested again to ensure the assembly accuracy between the spindle 200 and the part to be installed 300.

[0050] After the assembly process is completed, the movable frame 2 needs to return to a position away from the first support plate 11. Optionally, the movable frame 2 can return to its initial position by gravity, or by being pulled back to its initial position by the drive component 3, or by being set up with a reset component to return the movable frame 2 to its initial position. This embodiment of the application does not limit this.

[0051] Thus, the assembly fixture 100 provided in this embodiment can support the spindle 200 via the first support plate 11 and the movable frame 2 supports the part to be installed 300. The positioning function of the first and second mounting holes positions the spindle 200 and the part to be installed 300, ensuring that their vertical positions are consistent. Simultaneously, the driving component 3 drives the movable frame 2 to bring the part to be installed 300 closer to the spindle 200, completing the assembly of the spindle 200 and the part to be installed 300. The cooperation of the first support plate 11, the movable frame 2, and the driving component 3 ensures the assembly accuracy of the spindle 200 and the part to be installed 300, reducing errors caused by manual assembly of the spindle 200.

[0052] Please see Figure 1 and Figure 2 In some embodiments, the assembly fixture 100 further includes: a mounting flange 4, which is detachably disposed on the first support plate 11. The mounting flange 4 is used to connect the spindle 200 and the first mounting hole. The mounting flange 4 includes a first positioning hole through which the spindle 200 can pass. The first positioning hole can restrict the radial movement of the spindle 200.

[0053] Specifically, the mounting flange 4 is detachably mounted on the first support plate 11. The first positioning hole on the mounting flange 4 is tightly fitted with the spindle 200, which helps to restrict the movement of the spindle 200 in the radial direction, thereby positioning the spindle 200 and ensuring the stability and accuracy of the spindle 200 during assembly.

[0054] Furthermore, the first support plate 11 may be provided with a countersunk hole to accommodate the mounting flange 4. By providing a countersunk hole in the first support plate 11, a precise positioning reference can be provided for the mounting flange 4. When the mounting flange 4 is placed in the countersunk hole, the edge of the mounting flange 4 fits tightly against the sidewall of the countersunk hole, thereby restricting the horizontal movement of the mounting flange 4. This restriction helps ensure precise alignment between the mounting flange 4 and the spindle 200, improving assembly accuracy. Simultaneously, the countersunk hole design also increases the contact area between the mounting flange 4 and the first support plate 11, thereby improving the stability of the connection.

[0055] Furthermore, the countersunk hole also serves to protect the mounting flange 4 and the first support plate 11. During installation, the edge of the mounting flange 4 may rub or collide with the surface of the first support plate 11, causing surface damage or scratches. The countersunk hole design confines this friction or collision within the countersunk hole, thus protecting the surfaces of the mounting flange 4 and the first support plate 11 from damage.

[0056] Optionally, the detachable connection between the mounting flange 4 and the first support plate 11 can be a bolt connection or a snap-fit ​​connection; this embodiment does not limit this. It is understood that the mounting flange 4 can be replaced according to different sizes of spindles 200. The replaceability of the mounting flange 4 allows the assembly fixture 100 to adapt to various different spindles 200 and parts 300 to be installed, further broadening the application range of the fixture and enhancing production flexibility.

[0057] Please see Figure 4 , Figure 4 This document provides a cross-sectional view of the first type of spindle 200 and assembly fixture 100, as well as a partially enlarged view of the mating support 5, provided in the embodiments of this application. In some embodiments, the area of ​​the first mounting hole is larger than the maximum cross-sectional area of ​​the component to be installed 300, so that the component to be installed 300 can pass through the first mounting hole. Specifically, when designing the first mounting hole on the first support plate 11, the area of ​​the first mounting hole is ensured to be larger than the maximum cross-sectional area of ​​the component to be installed 300. This ensures the smooth passage of the component to be installed 300 during the installation process, allowing it to pass through the first mounting hole both before and after assembly. This enables the assembled spindle 200 and the component to be installed 300 to be lifted out together from the first mounting hole, simplifying the operation process and reducing technical difficulty.

[0058] Please see Figure 1 and Figure 4 In some embodiments, the assembly fixture 100 further includes a mating support 5, which is detachably disposed on the movable frame 2. The mating support 5 is used to connect the component to be installed 300 and the second mounting hole. The mating support 5 includes a second positioning hole through which at least a portion of the component to be installed 300 can pass. The second positioning hole can restrict the radial movement of the component to be installed 300.

[0059] Furthermore, the mating support 5, by mating with the second mounting hole, ensures the position of the mating support 5, and the second positioning hole on the mating support 5 effectively restricts the radial movement of the part to be installed 300, thereby ensuring the position of the part to be installed 300 during the assembly process, as well as the stability and accuracy of the part to be installed 300 during the assembly process.

[0060] The supporting component 5, as a detachable assembly on the movable frame 2, connects the part to be installed 300 to the second mounting hole. Simultaneously, through a second positioning hole with a different area than the second mounting hole, it provides stable support for parts 300 of different sizes. The detachability and replaceability of the supporting component 5 endow the assembly fixture 100 with flexibility and versatility. By replacing different sizes or types of supporting components 5, the assembly fixture 100 can adapt to various parts 300 to be installed, meeting diverse assembly needs and reducing the production cost and maintenance difficulty of the fixture.

[0061] Please see Figures 1 to 4 In some embodiments, the bracket 1 includes a guide rod 12 that extends vertically, and the movable frame 2 is sleeved on the guide rod 12; the driving member 3 is disposed on the bracket 1 and located below the movable frame 2, and the driving end of the driving member 3 can move vertically to push the movable frame 2 to move along the extension direction of the guide rod 12.

[0062] The guide rod 12 extends vertically, providing support and guidance for the movable frame 2, ensuring stable movement of the movable frame 2 in the vertical direction, and preventing swaying or displacement during assembly or movement. The movable frame 2 is fitted onto the guide rod 12 and can slide along the extension direction of the guide rod 12, meeting the needs of assembly and adjustment.

[0063] The drive component 3 is located below the bracket 1. The drive end of the drive component 3 can move in the vertical direction, directly pushing the movable frame 2 to move along the extension direction of the guide rod 12. This simplifies the transmission mechanism between the drive component 3 and the movable frame 2, reduces energy loss, and makes the movement of the movable frame 2 more responsive and more precisely controlled.

[0064] Optionally, the number of guide rods 12 can be set to four, and the first support plate 11 can be set to a square shape. The four guide rods 12 are respectively set at the four corners of the first support plate 11 to ensure the stability of the guide rods 12 and the first support plate 11, forming a solid support, ensuring that the movable frame 2 can move up and down without being affected by shaking, thereby ensuring the assembly accuracy of the spindle 200.

[0065] In addition, a structure for supporting the guide rod 12 can be provided on the guide rod 12 to prevent the guide rod 12 from tilting or falling off under the movement of the movable frame 2, thus ensuring the stability of the bracket 1.

[0066] Please see Figures 1 to 4In some embodiments, the assembly fixture 100 further includes a linear bearing 6, which is disposed between the movable frame 2 and the guide rod 12. The linear bearing 6 is movable along the extension direction of the guide rod 12. The linear bearing 6 being disposed between the movable frame 2 and the guide rod 12 enables the movable frame 2 to move smoothly and with low friction along the guide rod 12, thereby improving the overall performance of the assembly fixture 100 while ensuring accuracy and rigidity.

[0067] Specifically, the linear bearing 6, through its internal rolling elements such as balls or rollers, forms contact with the guide rod 12, reducing the coefficient of friction between the linear bearing 6 and the guide rod 12. This reduces the resistance encountered by the movable frame 2 during movement, extends the service life of the guide rod 12 and the movable frame 2, and effectively reduces maintenance costs caused by friction and wear.

[0068] Meanwhile, the rolling elements inside the linear bearing 6 can evenly distribute the load, avoiding deformation or displacement of the guide rod 12 due to excessive local pressure, thereby ensuring the stable and precise movement of the movable frame 2 in the vertical direction, and further improving the assembly accuracy and reliability.

[0069] Please see Figure 5 , Figure 5 The diagram below shows the structure of the locking member 7 provided in the embodiments of this application. In some embodiments, the assembly fixture 100 further includes a locking member 7, which is sleeved on the guide rod 12 and located below the movable frame 2. The locking member 7 has a locked state and an unlocked state. When the locking member 7 is in the locked state, it can prevent the movable frame 2 from moving away from the first support plate 11. When the locking member 7 is in the unlocked state, the movable frame 2 can move away from the first support plate 11.

[0070] The locking element 7 has two states: locked and unlocked, which can control the movement of the movable frame 2. When the locking element 7 is in the locked state, it can prevent the movable frame 2 from moving away from the first support plate 11, ensuring the stability of the movable frame 2 in its current position. When the locking element 7 is switched to the unlocked state, it allows the movable frame 2 to move away from the first support plate 11 along the guide rod 12. This allows the movable frame 2 to be adjusted to the optimal position according to assembly requirements.

[0071] Furthermore, in the locked state, the locking element 7 tightly fits or locks the guide rod 12, thereby effectively preventing the movable frame 2 from continuing to move downward, preventing the movable frame 2 from falling further due to accidents or misoperation, and also ensuring the safety and accuracy of the assembly process.

[0072] Optionally, the locking element 7 can be a threaded locking ring, a snap-on locking element 7, a lever-type locking element 7, or an electromagnetic locking element 7, etc., and the embodiments of this application do not limit this.

[0073] Please see Figure 5 In some embodiments, the locking member 7 includes: a limiting ring 71, which is sleeved on the guide rod 12, and has an opening 711 along the radial direction of the guide rod 12, dividing the limiting ring 71 into a first end and a second end; the limiting ring 71 includes a mounting part 72 and a connecting hole 73, with the mounting part 72 located at the first end and the connecting hole 73 located at the second end; and a connecting rod, which passes through the connecting hole 73 and is threadedly connected to the mounting part 72 to adjust the distance between the first end and the second end.

[0074] A limiting ring 71 is sleeved on the guide rod 12, and the limiting ring 71 has an opening 711 along the radial direction of the guide rod 12. This opening 711 divides the limiting ring 71 into a first end and a second end, so that the limiting ring 71 can elastically deform within a certain range, thereby better adapting to the shape and size of the guide rod 12.

[0075] The first end of the limiting ring 71 has a mounting portion 72 for connection and fixation. The second end has a connecting hole 73, which allows a connecting rod to pass through, thus connecting the limiting ring 71 to the connecting rod. The connecting rod passes through the connecting hole 73 at the second end of the limiting ring 71 and is threadedly connected to the mounting portion 72 at the first end. The distance between the first and second ends can be adjusted by rotating the connecting rod. This adjustment function allows the locking member 7 to adjust its locked and unlocked states by rotating the connecting rod.

[0076] Please see Figures 1 to 4 In some embodiments, the bracket 1 further includes: a second support plate 13, the second support plate 13 and the first support plate 11 are arranged at intervals in the vertical direction, the second support plate 13 is located below the movable frame 2; and a plurality of support adjustment members 14, the plurality of support adjustment members 14 are disposed on the second support plate 13 and located on the side of the second support plate 13 away from the first support plate 11, the plurality of support adjustment members 14 can adjust the levelness of the second support plate 13.

[0077] The second support plate 13 and the first support plate 11 are arranged vertically at intervals, with the second support plate 13 located below the movable frame 2. Multiple support adjustment members 14 are disposed on the second support plate 13, located on the side of the second support plate 13 away from the first support plate 11, i.e., on the lower surface of the second support plate 13, for supporting the second support plate 13, the guide rod 12, and the first support plate 11. The support adjustment members 14 can adjust the height of the second support plate 13 above the ground, thereby adjusting the levelness of the second support plate 13 through the adjustment of multiple support adjustment members 14, ensuring the levelness, stability, and balance of the entire support frame 1 structure.

[0078] It is understandable that the support adjustment component 14 enhances the adaptability of the assembly tooling 100 to different environments. Whether on flat ground or in complex and varied terrain, the support adjustment component 14 can be adjusted to make the bracket 1 reach an ideal level, thus improving the practicality of the bracket 1.

[0079] In addition, the support adjustment member 14 also serves to protect the structure of the bracket 1. By maintaining the horizontal state of the bracket 1, the support adjustment member 14 can reduce structural damage caused by uneven stress, thereby extending the service life of the bracket 1.

[0080] Optionally, an adsorption component can be provided on the side of the support adjustment component 14 that is in contact with the ground to ensure that the bracket 1 is stably adsorbed to the ground, thereby reducing the safety hazards caused by the tilting or shaking of the bracket 1.
