Description

Technical Field

[0001] The utility model relates to the technical field of plastic spraying of stabilizer bars, in particular to a plastic spraying and shielding tool for stabilizer bars. Background Art

[0002] Stabilizer bars are important auxiliary elastic components in automotive suspensions, primarily used to increase suspension roll stiffness, reduce body roll, and enhance vehicle stability. With the increasing axle loads of new energy vehicles, the forces borne by the stabilizer bar's fixed ends (typically its two ends) are also increasing, placing higher demands on their tightening and anti-loosening capabilities.

[0003] Currently, the most common way to treat the surface of the stabilizer bar is to spray plastic first and then dip it in paint. This treatment method will cause the paint film on the fixed end of the stabilizer bar to be thicker, which will consume part of the axial force when the stabilizer bar and the connecting rod are tightened. Tightening will also damage part of the paint film, further causing serious attenuation of the axial force, and ultimately causing abnormal noise at the connection point between the stabilizer bar and the connecting rod. The tightening and anti-loosening ability of the fixed end will also be affected, causing market complaints. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] It should be noted that the terms "first", "second", "third", "fourth", etc. in the description and claims of the present utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The utility model provides a spray-molding shielding tool for a stabilizer bar, which is suitable for the spray-molding process of the stabilizer bar and prevents the mounting surface of the fixed end from being sprayed with a paint film by suspending and shielding the fixed end of the stabilizer bar, that is, the end portion.

[0025] See also Figures 1 to 3The spray-painted masking tool in the present invention includes a first masking tool 1 and a second masking tool 2. The first masking tool 1 is used to mask the first fixed end 31 of the stabilizer bar 3 to be sprayed with plastic, and the second masking tool 2 is used to mask the second fixed end 32 of the stabilizer bar 3 to be sprayed with plastic. The first masking tool 1 masks the first fixed end 31 by covering the two opposite surfaces of the first fixed end 31 respectively, and the second masking tool 2 masks the second fixed end 32 by covering the two opposite surfaces of the second fixed end 32 respectively. Specifically, in this embodiment, the stabilizer bar 3 to be sprayed with plastic is a symmetrical structure, so the first fixed end 31 and the second fixed end 32 are symmetrical to each other. The two opposite surfaces of the first fixed end 31 refer to the upper and lower mounting surfaces of the first fixed end 31, and the two opposite surfaces of the second fixed end 32 refer to the upper and lower mounting surfaces of the second fixed end 32. The first fixed end 31 is hung at a relatively high position on the tool, and the second fixed end 32 naturally droops under the action of gravity and is located at a relatively low position on the tool. The first shielding tool 1 covers and shields the upper mounting surface of the first fixed end 31 from above, and shields the lower mounting surface of the first fixed end 31 from below. The second shielding tool 2 covers and shields the upper mounting surface of the second fixed end 32 from above, and shields the lower mounting surface of the second fixed end 32 from below. After the first fixed end 31 and the second fixed end 32 are shielded, the other parts of the stabilizer bar 3 to be sprayed with plastic will be sprayed evenly. The present invention shields the first fixed end 31 and the second fixed end 32 of the stabilizer bar during the spraying process, so that the mounting surfaces on the first fixed end 31 and the second fixed end 32 are not sprayed with paint film, ensuring that the paint film thickness on the first fixed end 31 and the second fixed end 32 is small during the subsequent dipping process, reducing the axial force attenuation phenomenon during the subsequent assembly of the stabilizer bar, eliminating the risk of subsequent loosening and abnormal noise, and at the same time, can spray plastic normally on other parts of the stabilizer bar, making other parts of the stabilizer bar less prone to rust.

[0026] Please also refer to Figure 4Furthermore, the first shielding tooling 1 in the present invention includes a first hook body 11, a first shielding piece 12 and a first sleeve 13. The first fixed end 31 is suspended on the plastic-sprayed shielding tooling through the first hook body 11. The first shielding piece 12 is protruded on the first hook body 11. The lower mounting surface of the first fixed end 31 contacts the first shielding piece 12 and is shielded by the first shielding piece 12. The first sleeve 13 is detachably arranged on the first hook body 11, and the upper mounting surface of the first fixed end 31 is covered and shielded by the first sleeve 13. Specifically, in this embodiment, the first hook body 11 is "J"-shaped, that is, the first hook body 11 is provided with a relatively long large end, a relatively short small end and a bending portion connecting the large end and the small end, wherein the small end is used to hang the first fixed end 31, and the small end passes through the connecting hole 33 on the first fixed end 31; the first shielding piece 12 is provided at the small end, and the first shielding piece 12 is a disc-shaped protrusion fixedly connected to the first hook body 11, and its size is larger than the connecting hole 33 but smaller than the first fixed end 31. When installed, the first shielding piece 12 is located below the first fixed end 31, that is, the upper end of the first shielding piece 12 contacts the lower mounting surface of the first fixed end 31, thereby shielding the lower mounting surface of the first fixed end 31. When installed, the first sleeve 13 can be placed above the first fixed end 31. The first sleeve 13 also includes a first positioning portion, which is disposed within the first sleeve 13. The first positioning portion is sleeved on the first hook body 11 and fixed relative to the first hook body 11. The first sleeve 13 is detachably mounted on the first hook body 11 via the first positioning portion. Specifically, the first sleeve 13 is detachably mounted on the small end of the first hook body 11 via the first positioning portion. When hanging the first fixed end 31, first pass the small end through the connecting hole 33 on the first fixed end 31, then remove the external force, so that the first fixed end 31 naturally falls onto the first shielding piece 12 under the action of gravity and contacts the upper surface of the first shielding piece 12, and then place the first sleeve 13 on the first hook body 11, so that the first sleeve 13 contacts the upper surface of the first fixed end 31, completing the shielding of the upper and lower mounting surfaces of the first fixed end 31.

[0027] Please also refer to Figure 5Furthermore, the second shielding tooling 2 in the present invention includes a second hook body 21, a second shielding piece 22 and a third shielding piece 23, the second fixed end 32 is clamped between the second shielding piece 22 and the third shielding piece 23, the upper mounting surface of the second fixed end 32 is in contact with the second shielding piece 22 and is shielded by the second shielding piece 22, the lower mounting surface of the second fixed end 32 is in contact with the third shielding piece 23 and is shielded by the third shielding piece 23, and the second shielding piece 22 and the third shielding piece 23 are fixedly connected as a whole through the second hook body 21. Specifically, in this embodiment, the second shielding piece 22 and the third shielding piece 23 are both disc-shaped protrusions fixedly connected to the second hook body 21. Their sizes are larger than the connecting hole 33 but smaller than the second fixed end 32. The second shielding piece 22 and the third shielding piece 23 are relatively fixed to the second fixed end 32. The second shielding piece 22 is arranged above the second fixed end 32 and shields the second fixed end 32 from above the second fixed end 32. The third shielding piece 23 is arranged below the third fixed end and shields the second fixed end 32 from below the second fixed end 32. The second hook body 21 is "C"-shaped, that is, the second hook body 21 is provided with two bending portions facing opposite each other, and the second shielding piece 22 and the third shielding piece 23 are respectively arranged at the ends of these two opposite bending portions. After the first fixed end 31 is hung, the second fixed end 32 is placed between the second shielding piece 22 and the third shielding piece 23. The second shielding piece 22, the second fixed end 32 and the third shielding piece 23 remain relatively fixed due to the clearance fit with extremely small gaps. During this process, the second shielding tooling 2 also naturally hangs down with the second fixed end 32 under the action of gravity.

[0028] Furthermore, the spray-painting masking tool in the present invention also includes a tool frame 4, which is used to fix the first masking tool 1, and a plurality of first masking tools 1 are detachably arranged on the tool frame 4. It is easy to understand that one first masking tool 1 can correspond to the hanging of the first fixed end 31 of the stabilizing bar 3 to be sprayed, so the number of first masking tools 1 set on the tool frame 4 can be regarded as the number of stabilizing bars 3 to be sprayed when performing one spray-painting process. In this embodiment, the tool frame 4 is an inverted "T" shape, which includes a vertical vertical bar, a horizontal horizontal bar and a positioning bar 41 protruding from the horizontal bar. The two positioning bars 41 on the horizontal bar can hang two first masking tools 1 respectively. By correspondingly equipping two second masking tools 2, it can be used to hang and spray two stabilizing bars 3 to be sprayed at the same time. The first shielding tool 1 also includes a sleeve-shaped first connecting portion 14, which is fixed relative to the positioning rod 41 through the second positioning portion inside the first connecting portion 14. The first connecting portion 14 is detachably provided on the tool frame 4 through the second positioning portion. The first connecting portion 14 is integrally connected to the first hook body 11. Specifically, the first connecting portion 14 is integrally connected to the large end of the first hook body 11. That is, the first shielding tool 1 is installed on the tool frame 4 through the first connecting portion 14. The utility model realizes the simultaneous suspension of multiple stabilizing rods 3 to be sprayed by arranging a plurality of positioning rods 41 for suspending the first shielding tool 1 on the tool frame 4, and the first shielding tool 1 and the tool frame 4 are detachably connected through the first connecting portion 14. The cost is low and the operation is simple, and the application prospect is good.

[0029] In summary, the plastic spraying masking tooling of the stabilizer bar of the present invention masks the first fixed end and the second fixed end of the stabilizer bar during the plastic spraying process, so that the mounting surfaces on the first fixed end and the second fixed end are not sprayed with paint film, ensuring that the thickness of the paint film on the first fixed end and the second fixed end is small during the subsequent dipping paint process, reducing the axial force attenuation phenomenon during the subsequent assembly of the stabilizer bar, eliminating the risk of subsequent loosening and abnormal noise, and at the same time can spray plastic normally on other parts of the stabilizer bar, so that other parts of the stabilizer bar are not prone to rust.
