It achieves efficient and large-scale production by breaking down the production process into multiple continuous steps and performing processing, assembly and other operations on the assembly line in a certain order and rhythm.

[0003] In order to achieve rotation, the existing technology generally uses a double-speed chain assembly line tooling plate, whose structural characteristics are: usually made of multi-layer boards with anti-static rubber and other materials, the bottom is installed on the double-speed chain, and can move along the chain in a cycle. A rotating mechanism is provided on the plate, such as a slewing bearing, so that the tooling plate can rotate 360°; or a rotating tooling fixture is combined with a mobile platform, and its structural characteristics are: the rotating tooling fixture part usually includes a support table, a rotating shaft, a turntable, a screw rod, a slider and other components, and the clamping and loosening of the workpiece are achieved through the cooperation of the screw rod and the slider, and the turntable is connected to the support table through the rotating shaft to achieve 360° rotation.

[0004] The tooling plates of the double-speed chain assembly line generally have the problem of tooling plate wear: the tooling plates frequently move and start and stop on the double-speed chain, and the friction with the chain and guide rails can easily cause wear on the tooling plate surface, especially under long-term high-load operation, which may affect the service life and positioning accuracy of the tooling plate; and the combination of rotating tooling fixtures and mobile platforms has the problem of difficulty in maintaining accuracy: during the long-term use of rotating tooling fixtures, due to frequent rotation and clamping actions, problems such as shaft wear and turntable eccentricity may occur, affecting the rotation accuracy and positioning accuracy of the tooling, and thus affecting the processing quality of the product. At the same time, assembly is more difficult. Utility Model Content

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments described below are intended to facilitate understanding of the present invention and do not have any limiting effect on the present invention.

[0027] Example 1

[0028] This application provides a specific implementation of a production line tool for fan assembly, such as Figure 1 The assembly line tooling for fan assembly includes:

[0029] A lower tooling plate 1 provided on the assembly line for moving back and forth with the assembly line;

[0030] and an upper tooling plate 2 rotatably arranged on the lower tooling plate 1 for carrying the fan;

[0031] Among them, such as Figure 2 As shown, the lower tooling plate 1 includes a lower plate body 1 - 1 and a rotating shaft 1 - 2 provided on the lower plate body 1 - 1 .

[0032] like Figure 3 As shown, in order to stably install the rotating shaft 1-2 on the lower plate body 1-1, it also includes: a pad 1-4 set on the rotating shaft 1-2. During installation, the rotating shaft 1-2 and the pad 1-4 are fixedly connected, and the pad 1-4 is fixedly connected to the lower plate body 1-1 by screws.

[0033] The lower plate body 1-1 is preferably made of nylon material, which has the advantages of high strength, good wear resistance and good corrosion resistance.

[0034] When in use, the fan is placed on the upper tooling plate 2. This structure will cause the fan to fall off when the assembly line is started. In order to solve this technical problem, Figure 4As shown in the figure, as a specific embodiment, the upper tooling plate 2 includes an upper plate body 2-1, a positioning block assembly 2-2 provided on the upper plate body 2-1 for limiting the position of the fan hanger, and a support block assembly 2-3 provided on the upper plate body 2-1 for limiting the position of the fan casing. The design of the upper tooling plate 2 ensures that the fan will not fall off even when the assembly line is in motion.

[0035] Among them, such as Figure 4 As shown, the positioning block assembly 2-2 includes a first positioning block 2-2-1 and a second positioning block 2-2-2 arranged in parallel on the upper plate body 2-1. Specifically, the distance between the first positioning block 2-2-1 and the second positioning block 2-2-2 conforms to the width of the wind turbine hanger.

[0036] The support block assembly 2-3 includes a first support block 2-3-1 and a second support block 2-3-2 arranged side by side on the upper plate body 2-1. The distance between the first support block 2-3-1 and the second support block 2-3-2 conforms to the width of the fan casing.

[0037] In this embodiment, the first support block 2-3-1 and the second support block 2-3-2 each comprise two parallel block structures, with the fan casing being clamped by the gap between the two block structures. As an alternative embodiment of the first support block 2-3-1 and the second support block 2-3-2, other similar structures having a slot for clamping the fan casing, such as a U-shaped structure, may be used.

[0038] In order to ensure the stable connection between the upper plate body 2-1 and the rotating shaft 1-2, it also includes: a sleeve 2-4 provided on the upper tooling plate 2 for being sleeved on the rotating shaft 1-2 and rotating around the rotating shaft 1-2. Figure 5 As shown, this design can ensure that the upper plate body 2-1 rotates relative to the lower plate body 1-1.

[0039] To reduce eccentric loads: When the rotating shaft 1-2 is in operation, if its installation position deviates from the center of the lower plate body 1-2, the supporting force on the rotating shaft 1-2 will be uneven, generating an eccentric load. This will not only increase wear between the rotating shaft 1-2 and the sleeve 2-4, but may also cause vibration and noise, and even affect the stability and service life of the entire device. Installing it in the center can evenly distribute the supporting force on the rotating shaft, avoiding the generation of eccentric loads. Therefore, the rotating shaft 1-2 is installed at the center of the lower plate body 1-1, and the sleeve 2-4 is installed at the center of the upper plate body 2-1.

[0040] During production, the positioning block assembly 2-2 is made of wood, while the upper plate body 2-1 and support block assembly 2-3 are made of nylon. The reasons for choosing wood for positioning block assembly 2-2 include: good processing properties; certain shock-absorbing and cushioning properties: Wood has a certain degree of elasticity and shock-absorbing capacity. When subjected to external force, it can absorb some energy, acting as a buffer, reducing the impact and damage to other components. Wooden positioning block assemblies have certain advantages for some components that require protection or in work environments with certain vibrations; and insulation properties: Wood is a good insulating material. In some equipment that requires electrical insulation, using wooden positioning block assemblies can prevent electrical short circuits and other problems, thereby improving equipment safety.

[0041] The reasons why nylon is selected as the material for the upper plate body 2-1 and the support block assembly 2-3 include: excellent mechanical properties, good wear resistance, self-lubrication, corrosion resistance, good electrical insulation, etc.

[0042] Although the way in which the rotating shaft 1-2 cooperates with the shaft sleeve 2-4 can adjust the relative distance between the lower plate body 1-1 and the upper plate body 2-1, it is difficult to balance the force on the upper plate body 2-1 because the upper tooling plate 2 needs to be installed with a fan, and the requirement for rapid adjustment cannot be achieved. In order to solve this technical problem, the present application provides a specific implementation method, such as Figure 3 As shown, it also includes: a plurality of universal balls 1-3 provided on the lower plate body 1-1 for supporting the upper tooling plate 2.

[0043] In order to realize the rotation of the upper tooling plate 2 relative to the lower tooling plate 1 in any direction, as shown in FIG. Figure 6 As shown in FIG. 1 , as a preferred embodiment, a plurality of universal balls 1-3 are evenly arranged on the lower plate body 1-1 around the rotation axis 1-2. The number of universal balls 1-3 is generally an even number such as 2, 4, 6, or 8. Figure 3 As shown, the upper tooling plate 2 is rotated 45°. This design allows for translation in any direction: the circumferentially arranged universal balls can roll freely in all directions within the plane, allowing objects placed on them to easily achieve forward, backward, left, right, and diagonal translational motion without being restricted to a specific direction, providing great flexibility for production operations. In addition to translation, the circumferential arrangement of universal balls also allows objects to rotate 360° around their vertical axis. Furthermore, it disperses pressure, ensuring that the lower tooling plate 1 has the ability to evenly load the load.

[0044] During the rotation process, the shape of the surface where the universal ball 1-3 contacts the upper plate body 2-1 affects the smoothness of the rotation process. In order to achieve a good rotation effect, the universal ball 1-3 is in point contact with the upper plate body 2-1 at least during the rotation process.

[0045] Example 2

[0046] Based on the assembly line tooling for fan assembly in Example 1, Figure 7 As shown, the present application provides an assembly line, specifically comprising: a non-powered conveying roller 4 for supporting and transmitting the assembly line tooling described in Example 1 and a tooling frame 3 provided on both ends of the non-powered conveying roller 4 for axially limiting the lower tooling plate 1.

[0047] The lower fixture plate 1 moves forward and backward with the unpowered conveying roller 4 and does not move axially, thereby preventing the fan from falling during the operation of the assembly line.

[0048] When in use, the fan product is placed on the assembly line fixture. The use process includes:

[0049] 1. Prepare the parts to be assembled;

[0050] 2. First, place the fan base on the positioning block assembly 2-2 of the upper plate body 2-1, which can be rotated to meet the installation requirements in all directions. Then, install the motor on the fan base - left and right volutes (based on the positioning positions, namely the first support block 2-3-1 and the second support block 2-3-2) - left and right impellers - left and right air inlets - left and right mesh covers and other components, and tighten and loosen them according to the required torque. The entire assembly process is completed on the fan assembly line;

[0051] 3. Because the upper tooling plate 2 and the lower tooling plate 1 are connected by an axis, the upper and lower tooling plates can be rotated 360 degrees by using the universal balls 1-3 in the lower tooling plate 1 for the parts that need to be assembled, so that workers can assemble in any direction, saving manpower, reducing labor power, and improving overall assembly efficiency.

[0052] The utility model discloses an assembly line which is easy to use, low in cost, durable, easy to assemble and disassemble, and saves time and effort. It adopts a sliding design concept, and the operator can easily push the product to the next process after installation. The tooling is overall stable and of reliable quality, which significantly improves production efficiency and greatly saves labor costs. It can improve production efficiency, save labor and effort, facilitate operation, and save costs.

[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
