Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, and in particular to a brush plate assembly tooling. Background Technology

[0002] The traditional assembly line process for installing brush discs using bolts presents a significant efficiency bottleneck. This process requires securing the brush disc to the flange using multiple sets of bolts and nuts. During operation, workers must first precisely align the holes on the brush disc, flange, and nuts, then insert the bolts with flat spring washers through the holes, and finally secure them with sleeves and tightening tools.

[0003] However, in this process, from the initial alignment of holes and placement of bolts with washers to the final assembly operation of tightening with tools, workers not only have to expend energy on hand-eye coordination, repeatedly aligning and fixing the bolts, but also frequently switch between manual and power tools for tightening. This operating mode not only prolongs the installation time of a single brush plate (about 2 minutes), resulting in low overall efficiency, but also easily causes muscle and visual fatigue in the operator.

[0004] To overcome this bottleneck, optimize the assembly process, shorten working hours, reduce the labor intensity of workers, and ensure assembly quality, it is urgent to develop a dedicated brush assembly fixture to achieve more efficient, stable, and user-friendly production.

[0006] This utility model is achieved using the following solution:

[0007] This utility model proposes a brush plate assembly fixture for assembling a brush plate and a flange using bolts and nuts. The fixture includes a main body with a flange positioning groove adapted to the shape of the flange. A nut groove is recessed on the bottom surface of the flange positioning groove for positioning the nut.

The multiple strip-shaped positioning protrusions are evenly distributed around the central axis of the flange, and the multiple strip-shaped positioning grooves are evenly distributed around the central axis of the flange positioning groove.

[0011] In one embodiment, the two positioning protrusions are located at opposite ends of the tooling body, and the side of the positioning protrusion that contacts the brush disk is an arc surface.

[0012] In one embodiment, the positioning protrusion is provided with a guide portion, which is connected to the side of the protrusion.

[0013] In one embodiment, the guide portion is chamfered.

[0014] In one embodiment, the nut groove is provided with an anti-rotation structure that matches the shape of the nut and is used to prevent the nut from rotating within the nut groove.

[0032] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0034] like Figures 1-11 As shown, this utility model provides a brush plate assembly fixture 10 for assembling a brush plate 40 and a flange 30 using bolts 50 and nuts 20. The brush plate 40 is provided with a plurality of first bolt holes 43, and the flange 30 is provided with a plurality of second bolt holes 32. The first bolt holes 43 and the second bolt holes 32 are used to pass through bolts 50.

[0035] The brush assembly fixture 10 includes a fixture body 11, which is generally a rectangular plate structure. A flange positioning groove 13 is provided in the middle of the fixture body 11. The flange positioning groove 13 is adapted to the shape of the flange 30. More specifically, the flange positioning groove 13 is adapted to the shape of the positioning surface 31 of the flange 30, so as to be used for positioning the flange 30.

[0036] The bottom surface of the flange positioning groove 13 is recessed with a nut groove 14, which is used to position the nut 20. The nut groove 14 is equipped with an anti-rotation structure 141 to prevent the nut 20 from rotating within the nut groove 14. The anti-rotation structure 141 matches the shape of the nut 20; for example, for a hexagonal lock nut, the anti-rotation structure 141 is a hexagonal cross-section anti-rotation structure. In this embodiment, six nut grooves 14 are shown, corresponding to six nuts 20. Of course, the number of nut grooves can be adjusted according to the actual number of nuts, for example, more or less than six.

[0037] Furthermore, the bottom surface of the flange positioning groove 13 is also recessed with a strip-shaped positioning groove 15, which includes a groove slope 151; the positioning surface 31 of the flange 30 is provided with a strip-shaped positioning protrusion 33, which includes a protruding slope 331. The shape of the strip-shaped positioning groove 15 is adapted to the strip-shaped positioning protrusion 33, and the shape of the groove slope 151 is matched with the protruding slope 331. Therefore, when the flange 30 is placed in the flange positioning groove 13, the positioning surface 31 of the flange 30 is opposite to the flange positioning groove 13. The flange 30 will directly rotate at a small angle due to the relative sliding between the protruding slope 331 and the groove slope 151, directly reaching the required position. At this time, the second bolt hole 32 is aligned with the nut groove 14, thereby positioning the flange 30 and facilitating the tightening of the bolt 50 for installation. Of course, in some other embodiments, the shape of the strip positioning groove 15 of the brush assembly tool 10 can be adapted to the shape of the actual flange 30 to form a more suitable positioning.

[0038] like Figure 4 , Figure 5 As shown, multiple strip-shaped positioning protrusions 33 and strip-shaped positioning grooves 15 are provided, with six strip-shaped positioning protrusions 33 and six strip-shaped positioning grooves 15 as shown in the figure. The multiple strip-shaped positioning protrusions 33 are evenly distributed around the central axis of the flange 30, and the multiple strip-shaped positioning grooves 15 are evenly distributed around the central axis of the flange positioning groove 13. Therefore, the flange 30 only needs to be rotated at a small angle to form a positioning with the strip-shaped positioning grooves 15, making positioning easier and operation more convenient.

[0039] In this embodiment, the tooling body 11 is also provided with a plurality of fixing holes 12. The fixing holes 12 are used to install the brush assembly tooling 10 on the workbench. In this embodiment, the fixing holes 12 are countersunk holes, and there are 4 fixing holes 12. The 4 fixing holes 12 are distributed around the flange positioning groove 13, and the space arrangement is more reasonable. Of course, in some other embodiments, more or fewer fixing holes 12 can be provided.

[0040] The main body 11 of the tooling is also provided with two positioning protrusions 16, which can limit the radial sides of the brush plate 40, thereby positioning the brush plate 40 on the brush plate assembly tooling 10. The two positioning protrusions 16 are located at opposite ends of the main body 11 of the tooling. The protruding side 161 of the positioning protrusion 16 that contacts the brush plate 40 is an arc surface, thereby more accurately positioning the brush plate 40 and aligning it with the center of the flange 30. During installation, only a small angular rotation adjustment of the brush plate 40 is needed to align the first bolt hole 43 with the second bolt hole 32. Furthermore, since the strip-shaped positioning protrusion 33 of the flange 30 cooperates with the strip-shaped positioning groove 15, it can also prevent the flange 30 from being rotated during the rotation adjustment of the brush plate 40, thereby greatly simplifying the assembly process.

[0041] The positioning protrusion 16 is also provided with a guide portion 162, which is connected to the side surface 161 of the protrusion. The guide portion 162 is used to guide the brush disk 40 to engage between the two positioning protrusions 16, making operation more convenient. The guide portion 162 can be chamfered; of course, in some other embodiments, the guide portion can also be a curved surface, etc.

[0042] The brush plate 40 includes an interconnected mounting plate 41 and a bristle section 42, with a first bolt hole 43 provided on the mounting plate 41.

[0043] When assembling the brush plate 40 and flange 30 using the brush plate assembly fixture 10 via bolts 50 and nuts 20, the following steps can be taken:

[0044] Step S1: Refer to Figure 7 Place the brush assembly fixture 10 on a workbench and place the nut 20 upside down in the nut groove 14.

[0045] Step S2: Refer to Figure 8 In the figure, nut 20 is installed in nut groove 14. Nut groove 14 with hexagonal anti-rotation structure 141 has the function of restricting the rotational joints of x, y, and z axes and the moving joints of x and y axes for anti-loosening nut 20, which makes it easy to tighten bolt 50.

[0046] Step S3: Refer to Figures 8-9 When flange 30 is placed upside down into flange positioning groove 13, flange 30 will rotate at a small angle due to the relative sliding between protruding inclined surface 331 and groove inclined surface 151, directly aligning the second bolt hole 32 with the nut groove 14 (e.g., Figure 9 As shown in the figure, this facilitates subsequent tightening of bolt 50 for installation.

[0047] Step S4: Refer to Figures 9-10 Invert the brush plate 40 and place it inside. The two positioning protrusions 16 on both sides of the brush plate 40 will limit its position. Only a small angular adjustment of the brush plate 40 is needed to align the first bolt hole 43 with the second bolt hole 32 (e.g., Figure 10 As shown in the diagram, the brush plate 40, flange 30 and nut 20 are aligned.

[0048] Step S5: Refer to Figure 10 Insert bolts 50 and flat spring washers according to the directions shown in the diagram and tighten them diagonally to complete the assembly of brush plate 40 and flange 30; after bolts 50 are installed, as shown in the diagram... Figure 1 As shown.

[0049] Step S6: Refer to Figure 11The assembled brush assembly is taken out vertically. The brush assembly includes a brush 40, a flange 30, a bolt 50, and a nut 20 assembled as one piece.

[0050] By utilizing the structure of the above specific embodiments, the present invention can achieve the following beneficial effects:

[0051] 1. The brush plate assembly fixture 10 provided by this utility model is used for assembling the brush plate 40 and the flange 30 with bolts 50 and nuts 20. The flange 30 has obvious surface textures such as strip-shaped positioning protrusions 33. The brush plate assembly fixture 10 provided by this utility model is correspondingly designed with matching strip-shaped positioning grooves 15. By utilizing the concave-convex correspondence of the textures of the two, the flange 30 and the brush plate assembly fixture 10 can be quickly self-positioned, ensuring that the hole alignment and assembly can be performed efficiently and quickly.

[0052] 2. The present invention provides a nut groove 14, which allows the tooling to position the nut 20, thus saving the time of manually positioning the nut 20 when installing the brush plate 40.

[0053] 3. This utility model can complete the entire assembly process using only a screwdriver, eliminating the need for a sleeve for tightening nuts, thus saving tool costs, reducing installation workload, and improving production efficiency.

[0054] 4. This utility model allows installation operators to assemble the brush plate independently (approximately 30 seconds per piece), which is far more efficient than the assembly line process (approximately 2 minutes per piece), increasing efficiency by about 3 times.

[0055] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
