Technical Field

[0001] This utility model belongs to the field of automotive assembly technology, and specifically relates to an auxiliary device for spraying stabilizer bar ring positioning lines. Background Technology

[0002] The stabilizer bar is one of the core components of a car's suspension system. Its function is to suppress body roll when the vehicle is cornering by using its torsional characteristics, thereby significantly improving the vehicle's handling stability and driving safety. It is crucial to vehicle performance and driving safety.

[0003] In the assembly of automotive stabilizer bars, circular positioning guide lines need to be sprayed onto the surface of the stabilizer bar to ensure its precise installation. This process directly affects the assembly accuracy of the stabilizer bar, thereby impacting the vehicle's handling stability and safety. However, current technology lacks dedicated tools for spraying positioning guide lines onto stabilizer bars, relying mostly on manual measurement and marking to determine the position of the positioning lines. This method is prone to significant errors and makes it difficult to guarantee the symmetry and positional accuracy of the positioning lines. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide an auxiliary device for spraying the ring positioning line of a stabilizer bar.

[0005] This utility model provides a stabilizer bar annular positioning line spraying auxiliary device, including a central rod, the end of which is inserted into the mounting hole at the end of the stabilizer bar for adjusting the center distance of the central rod, and auxiliary spraying components are symmetrically arranged at both ends of the central rod; the auxiliary spraying components are located inside the mounting hole. The auxiliary spraying assembly includes a first rocker arm and a second rocker arm; the first rocker arm is fixedly connected to the central rod, and the second rocker arm is rotatably connected to the central rod; both the first rocker arm and the second rocker arm are provided with a semi-circular ring at their ends, and the second rocker arm rotates along the central rod so that the two semi-circular rings are engaged to form a ring-shaped marking mold.

[0006] A further embodiment is that the center rod is connected to the mounting hole via a plug ring, the outer wall of the plug ring is inserted into the mounting hole, an adjusting sleeve is provided inside the plug ring, the adjusting sleeve is threadedly connected to the plug ring, and the end of the center rod is fixedly connected to the adjusting sleeve.

[0007] A further embodiment is that the insertion ring has a positioning boss at one end near the center rod, and the positioning boss cooperates with the end face of the mounting hole to serve as a reference surface for the insertion depth.

[0008] A further embodiment is that a bearing is provided inside the adjusting sleeve, and the end of the central rod is inserted into the bearing; The outer ring of the bearing is interference-fitted with the inner wall of the adjusting sleeve, and the inner ring of the bearing is interference-fitted with the outer wall of the center rod.

[0009] A further embodiment is that the outer wall of the adjusting sleeve is provided with an adjusting mark, which serves as an identifier indicating that the center rod is centered.

[0010] A further embodiment is that the semicircular ring includes a first semicircular ring and a second semicircular ring, the first semicircular ring and the second semicircular ring are connected side by side by a connecting rod and a gap is left between the first semicircular ring and the second semicircular ring.

[0011] A further embodiment is that after the two semicircular rings are engaged, the two gaps overlap to form a circular notch.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a central rod inserted into the mounting hole at the end of the stabilizer rod and symmetrically arranged auxiliary spraying components to ensure that the position of the ring marking mold is symmetrical with the center of the stabilizer rod, avoiding errors caused by manual measurement and marking, thereby ensuring the symmetry and accuracy of the spraying positioning line and improving assembly quality.

[0013] This utility model uses a threaded connection structure of a plug ring and an adjusting sleeve, combined with an adjusting mark, to precisely adjust the center distance of the center rod, so that it can be quickly centered and fixed, adapting to stabilizing rods of different sizes, and enhancing the versatility and adjustment efficiency of the device.

[0014] This invention utilizes the rotational design of the first and second rocker arms to allow two semicircular rings to quickly engage and form a ring-shaped marking mold. Simultaneously, the gap between the semicircular rings is designed to create a circular notch, facilitating the passage of paint during spraying, simplifying the operation steps, and improving spraying speed and consistency.

[0016] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0017] like Figure 1 and Figure 2 As shown, this utility model provides an auxiliary device for spraying a ring positioning line on a stabilizer bar, including a central bar 3. The end of the central bar 3 is inserted into the mounting hole 2 at the end of the stabilizer bar 1. Auxiliary spraying components are symmetrically fixed at both ends of the central bar 3. Specifically, the auxiliary spraying components include a first rocker arm 4 and a second rocker arm 5. The first rocker arm 4 is fixedly connected to the central bar 3, and the second rocker arm 5 is rotatably connected to the central bar 3. Semicircular rings are respectively provided at the ends of the first rocker arm 4 and the second rocker arm 5. The second rocker arm 5 can rotate around the central bar 3, causing the two semicircular rings to engage and form a ring-shaped marking mold 6. The central bar 3 serves as a reference axis inserted into the mounting hole 2 of the stabilizer bar 1. The symmetrical arrangement of the two rocker arms ensures that the ring-shaped marking mold 6 is aligned with the center of the stabilizer bar 1. Rotating the second rocker arm 5 causes the semicircular rings to engage, forming a complete ring mold, which serves as a template for spraying the positioning line, ensuring accurate and symmetrical spraying.

[0018] like Figure 3 and Figure 4As shown, the center rod 3 is connected to the mounting hole 2 via a retaining ring 8. The outer wall of the retaining ring 8 is inserted into the mounting hole 2. An adjusting sleeve 10 is provided inside the retaining ring 8. A handle 11 is provided at the end of the adjusting sleeve 10 away from the center rod 3. The adjusting sleeve 10 is threadedly connected to the retaining ring 8, and the end of the center rod 3 is fixedly connected to the adjusting sleeve 10. A bearing 15 is provided inside the adjusting sleeve 10, and the end of the center rod 3 is inserted into the bearing 15. The outer ring of the bearing 15 is interference-fitted with the inner wall of the adjusting sleeve 10, and the inner ring of the bearing 15 is interference-fitted with the outer wall of the center rod 3. By rotating the adjusting sleeve 10, the axial position of the center rod 3 within the retaining ring 8 is adjusted using threaded transmission, thereby adjusting the center distance of the center rod 3. The bearing 15 ensures that the center rod 3 does not rotate with the adjusting sleeve 10 when adjusting its position. Specifically, when the center distance needs to be adjusted, the operator rotates the handle 11 at the end of the adjusting sleeve 10. Since the adjusting sleeve 10 is connected to the insert ring 8 via threads, rotation will cause it to move axially. When the adjusting sleeve 10 rotates relative to the inner ring of the bearing 15 with the outer ring of the bearing 15, the center rod 3 is only supported by the inner ring of the bearing and is pushed by the adjusting sleeve 10 to make axial linear motion, without rotating itself. This ensures that the first rocker arm 4, which is fixedly connected to the center rod 3, and the first semi-circular ring 12 at its end always maintain the preset orientation during the adjustment process, protecting these components from unexpected torque.

[0019] A positioning boss 9 is provided at one end of the insert ring 8 near the center rod 3. The positioning boss 9 serves as a reference surface for the insertion depth, ensuring that the insert ring 8 is inserted into the mounting hole 2 to a consistent depth each time, avoiding positional deviation and improving repeatability accuracy. In this embodiment, the outer wall of the adjusting sleeve 10 is provided with adjustment marks as a visual reference, which can help the user quickly adjust the center rod 3 to the centered position, ensuring symmetrical arrangement of the auxiliary spraying components and improving operational convenience and accuracy.

[0020] like Figure 5 As shown, in this embodiment, the semicircular ring includes a first semicircular ring 12 and a second semicircular ring 13. The first semicircular ring 12 and the second semicircular ring 13 are connected side by side by a connecting rod 14, with a gap between them. After the two semicircular rings are engaged, the two gaps overlap to form a circular notch, which is the notch for the spray positioning mark. The circular notch serves as the outlet for the spray positioning mark, ensuring that the paint is sprayed evenly to form a circular line, thus improving spraying efficiency and quality. In this embodiment, to ensure the stability of the two semicircular rings after engagement, the edges of the semicircular rings are magnets, and a magnetic connection is used after engagement.

[0021] like Figure 6As shown, when using this auxiliary device, the center rod 3 is first inserted into the mounting hole 2 of the stabilizer rod 1 through the insert rings 8 at both ends. The reference depth is determined by the positioning boss 9. Then, the adjusting sleeve 10 is rotated to precisely adjust the extension length of the center rod 3 so that it is centered and fixed. The second rocker arms 5 on both sides are rotated so that the semi-circular ring at the end of the second rocker arm is engaged with the semi-circular ring on the first rocker arm to form a complete ring marking mold. The ring notch formed by the overlapping gap on the mold is used for uniform spraying, which can form a ring positioning line with precise position and clear outline on the surface of the stabilizer rod 1, effectively ensuring the accuracy and consistency of the assembly reference.
