Description

Technical Field

[0001] This utility model relates to the technical field of protective devices in the manufacturing process of brake discs, and specifically to a brake disc paint masking device. Background Technology

[0002] like Figure 1 The diagram shows a type of automotive brake disc structure. After the brake disc 1 is machined, it needs to be painted. However, not all surfaces can be painted. For example, the brake surface 11 and the shaft hole 12 cannot be painted. Therefore, a masking device is needed to cover the non-painted surfaces during the painting process. Existing masking devices are generally fixed cover plates, but when used on both the brake surface and the shaft hole, the fit is often poor, necessitating further design optimization. Utility Model Content

[0003] The purpose of this invention is to provide a brake disc paint masking device to improve its performance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A brake disc painting masking device includes a masking ring and a masking cap. The upper side of the masking ring is connected to the connecting part of the hanging rod via a connecting rod. The masking cap is located at the center of the masking ring and is movably sleeved on the sleeve part of the hanging rod. The sleeve part is located below the connecting part. The hanging rod is provided with a clamping part above the connecting part for gripping by a robot arm.

[0006] Furthermore, the bottom side of the shielding ring is a shielding surface, and both the inner and outer edges of the shielding surface extend downward to form a shielding ring.

[0007] Furthermore, the upper side of the shielding ring is provided with a thickened portion in the central annular region, and one end of the connecting rod is connected to the thickened portion.

[0008] Furthermore, one end of the connecting rod is provided with a connecting seat, which is bolted to the thickened part.

[0009] Furthermore, at least two connecting rods are provided, evenly distributed along the circumference of the shielding ring.

[0010] Furthermore, the shielding cap has a frustum structure for engaging with and shielding the shaft hole of the brake disc.

[0011] Furthermore, the hanging rod is arranged vertically, and the lower end of the hanging rod is provided with a pin hole for inserting a limiting member to limit the lower end of the cover cap.

[0012] Furthermore, the clamping portion of the hanging rod includes a soft layer disposed on its outer periphery.

[0013] The beneficial effects of this utility model are:

[0014] The method of using the brake disc painting masking device of this utility model is as follows: Several brake discs to be painted are placed on a conveyor plate. Then, a robotic arm holds the upper part of the hanging rod of the painting masking device and delivers the painting masking device to the brake disc area. It is placed on the brake disc from top to bottom, with the masking ring of the painting masking device just touching the non-painted surface of the brake disc. At the same time, the masking cap is floating, and its lower cone enters the brake disc shaft hole by its own weight, adaptively fitting tightly with the shaft hole and partially covering the shaft hole. The brake disc painting masking device of this utility model is designed with a masking cap that can float freely axially within a certain range and has a conical circumference, so it can better contact and cooperate with the brake disc, achieving a better masking effect during painting. For brake discs with the same circumferential size but different flange thicknesses, the brake disc painting masking device of this utility model can adapt to different brake discs because its masking cap is movable, and is not limited to a specific brake disc.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0021] Embodiments of this utility model:

[0022] like Figures 2-3As shown, the brake disc paint masking device mainly consists of a masking ring 2, a masking cap 5, and a hanging rod 4, all of which are made of stainless steel for easy cleaning and corrosion resistance. The hanging rod 4 is vertically installed, perpendicular to the masking ring 2, and the upper side of the masking ring 2 is connected to the connecting part of the hanging rod 4 via a connecting rod 3.

[0023] The upper side of the shielding ring 2 has a thickened part 21 in the central annular area. That is, the thickened part 21 is also arranged around the circumference. The two sides of the thickened part 21 are beveled and transitionally connected to the thickened part 21. One end of the connecting rod 3 is connected to the thickened part 21 to improve the overall strength.

[0024] One end of the connecting rod 3 is provided with a connecting seat 31, which is bolted to the thickened part 21, resulting in high connection strength. At least two connecting rods 3 are provided, evenly distributed along the circumference of the shielding ring 2. In this embodiment, three connecting rods 3 are selected, which is simple in structure, meets structural stability requirements, and avoids excessive structure affecting normal painting operations. The connecting rod 3 is approximately L-shaped, with an upward bulge.

[0025] The bottom side of the shielding ring 2 is a shielding surface 22, which is an annular plane. In use, it can fit against the unpainted surface of the brake disc 1, and the size is also matched. Both the inner and outer edges of the shielding surface 22 extend downward to form a shielding ring 23. The shielding ring 23 is relatively thin, which can meet the protection of the outer edge of the unpainted surface of the brake disc 1.

[0026] The shielding cap 5 is located at the center of the shielding ring 2. The shielding cap 5 is movably sleeved on the sleeve part 41 of the hanging rod 4, which is located below the connecting part. The sleeve part 41 is a smooth rod, and the lower end of the hanging rod 4 has a pin hole 42 for inserting a limiting member to limit the lower end of the shielding cap 5. The limiting member can be a pin inserted into the pin hole 42, or a wire can be inserted through the pin hole 42 and then bent to limit the limit. The shielding cap 5 has a small amount of movement along the length of the hanging rod 4, such as a free movement of 1 cm.

[0027] The brake cover 5 has a frustum-shaped structure, used to mate with and cover the shaft hole of the brake disc 1. In use, after the covering device is positioned on the upper side of the brake disc 1, the lower frustum of the brake cover 5, under its own weight, enters the shaft hole of the brake disc 1, adaptively fitting snugly against the shaft hole. Furthermore, the upper diameter of the brake cover 5 is larger than the lower diameter, thus effectively providing coverage. To clarify, because the brake cover 5 has a frustum-shaped structure, the lower, smaller diameter section can be inserted into the shaft hole of the brake disc 1.

[0028] The hanging rod 4 has a clamping part 43 above the connecting part for gripping by the robotic arm. Furthermore, the clamping part 43 of the hanging rod 4 includes a soft layer (not shown in the figure) on its outer periphery, such as a rubber sleeve or a foamed plastic sleeve, giving the clamping part 43 a certain degree of elasticity, preventing the robotic arm grippers from clamping hard against each other, and improving clamping stability compared to directly clamping a smooth stainless steel surface. In other embodiments, friction textures can also be directly machined onto the outer periphery of the upper section of the hanging rod 4.

[0029] The method of using the brake disc painting masking device of this utility model is as follows: Several brake discs 1 to be painted are placed on a conveyor plate. Then, a robotic arm holds the upper part of the hanging rod 4 of the brake disc painting masking device and delivers the painting masking device to the brake disc area, placing it on the brake disc 1 from top to bottom. The masking ring 2 is just attached to the non-painted surface of the brake disc 1. This positioning can be achieved by a robotic arm and is not the technical solution of this utility model. At the same time, the cone at the bottom of the masking cap 5 enters the shaft hole of the brake disc 1 by its own weight, adaptively fitting tightly with the shaft hole. Figure 4 The image shows the state of the brake disc 1 paint masking device after it has been placed on the brake disc 1. The masking cap 5 is movable, thus allowing for better fit with the shaft hole of the brake disc 1. After each brake disc 1 paint masking device is placed on the brake disc 1, the conveyor tray sends the rotating disc along with the paint masking device out of the paint booth. After the painting is completed, the paint masking device is removed after leaving the paint booth.
