Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts manufacturing technology, specifically relating to a plug for polishing luggage racks. Background Technology
[0002] Luggage rack polishing is a production process in which the product is effectively clamped by a tooling and then polished by a power-driven robot equipped with a cloth wheel, resulting in a bright and smooth product surface.
[0003] The existing aluminum tubes of luggage racks with perforated surfaces are polished, but the holes are not protected, causing the holes to be rounded during the polishing process. This reduces the matching effect with the cover plate, resulting in unstable product quality and low pass rate. Summary of the Invention
[0004] This utility model addresses the aforementioned problems in the existing technology by proposing a plug that prevents the openings of luggage rack products from being rounded.
[0005] This utility model can be achieved through the following technical solutions:
[0006] A plug for polishing luggage racks, comprising:
[0007] A base, which is used to insert into the hole in the surface of the product to be polished;
[0008] A wear-resistant block is connected to the base. When the base is inserted into the product hole, the wear-resistant block is located at the hole opening.
[0009] A ball-head plunger, which is mounted on the side of the base;
[0010] A pin with a groove on its circumference is inserted into the base from the side away from the wear-resistant block until the groove engages with the steel ball of the ball-head plunger to fix the base.
[0011] As a further improvement of this utility model, the base is provided with at least one mounting hole, and the ball-head plunger is mounted on the side of the base through the mounting hole.
[0012] As a further improvement of this utility model, the base is also provided with a socket, and the pin is inserted into the base from the side away from the wear-resistant block through the socket.
[0013] As a further improvement of this utility model, the mounting hole and the insertion hole are arranged perpendicularly to each other.
[0014] As a further improvement of this utility model, the outer surface of the wear-resistant block extends out from the opening of the surface to be polished on the product.
[0015] As a further improvement of this utility model, the portion of the wear-resistant block extending beyond the product opening is shaped to resemble the surface of the product to be polished.
[0016] As a further improvement of this utility model, a spring is provided inside the ball plunger, and the spring always provides an outward thrust to the steel ball.
[0017] As a further improvement of this utility model, the base and the wear-resistant block are fixedly connected by copper welding.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. The engagement of the pin and the ball plunger ensures that the base will not move outward, while the wear-resistant block is located at the orifice, which can effectively prevent the orifice from being rounded during the polishing process, ensuring that the shape and size of the product orifice meet the design requirements and improving the product qualification rate.
[0020] 2. In addition, the addition of wear-resistant blocks significantly improves the wear resistance of the plug, extends its service life, reduces the frequency of replacement, and lowers production costs.
[0021] 3. The outer surface of the wear-resistant block extends from the opening of the product's surface to be polished. The part of the wear-resistant block that extends beyond the product's opening is similar in shape to the surface to be polished, ensuring that the surface around the opening is uniformly treated during the polishing process. This avoids the problem of local over-polishing or under-polishing, improves the quality and consistency of the polished surface, and effectively prevents the opening from being rounded during the polishing process. It ensures that the shape and size of the opening meet the design requirements and improves the product's pass rate. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.
[0026] like Figure 1-2 As shown, this utility model provides a plug for polishing luggage racks, comprising:
[0027] Base 100, which is used to be inserted into the hole of the surface of product 200 to be polished;
[0028] Wear-resistant block 110 is connected to base 100. When base 100 is inserted into the hole of product 200, wear-resistant block 110 is located at the hole opening.
[0029] A ball-head plunger 120 is mounted on the side of the base 100;
[0030] The pin 130 has a groove on its circumferential surface. The pin 130 is inserted from the side of the base 100 away from the wear-resistant block 110 until the groove engages with the steel ball 121 of the ball head plunger 120 to fix the base 100.
[0031] The engagement of the pin 130 and the ball plunger 120 ensures that the base 100 will not move outwards, while the wear-resistant block 110 is located at the orifice position, which can effectively prevent the orifice from being rounded during the polishing process, ensuring that the shape and size of the orifice of the product 200 meet the design requirements and improving the pass rate of the product 200.
[0032] In addition, the wear-resistant block 110 significantly improves the wear resistance of the plug, extends its service life, reduces the replacement frequency, and lowers production costs.
[0033] Preferably, the base 100 is provided with at least one mounting hole 140, and the ball plunger 120 is mounted on the side of the base 100 through the mounting hole 140.
[0034] Preferably, the base 100 is also provided with a socket 150. The pin 130 is inserted into the base 100 from the side away from the wear-resistant block 110 through the socket 150. The mounting hole 140 is perpendicularly intersected with the socket 150. Thus, after installing the ball plunger 120, the pin 130 is simply inserted along the socket 150 until the pin 130 engages with the ball plunger 120 to fix the base 100. The installation process is simple and convenient, improves efficiency, and forms a stable locking mechanism to ensure that the plug does not move out of the hole during the polishing process.
[0035] Preferably, the outer surface of the wear-resistant block 110 extends out of the orifice of the surface to be polished on the product 200. The portion of the wear-resistant block 110 extending beyond the orifice of the product 200 is similar in shape to the surface to be polished on the product 200. This ensures that the surface around the orifice is uniformly treated during the polishing process, avoids the problem of local over-polishing or under-polishing, improves the quality and consistency of the polished surface, and effectively prevents the orifice from being rounded during the polishing process. This ensures that the shape and size of the orifice meet the design requirements and improves the pass rate of the product 200.
[0036] Preferably, the ball plunger 120 is equipped with a spring 122 inside. The spring 122 always provides the steel ball 121 with an outward pushing force. Thus, the operator only needs to push the pin 130 inward, and the steel ball 121 can be embedded into the groove of the pin 130 under the action of the spring 122, ensuring a tight fit between the pin 130 and the ball plunger 120 and improving the stability of the entire plug block after installation.
[0037] Preferably, the base 100 and the wear-resistant block 110 are fixedly connected by copper welding to enhance the overall structural rigidity of the plug and ensure that the wear-resistant block 110 will not shake during the polishing process.
[0038] In addition, the wear-resistant block 110 in this embodiment is preferably made of tungsten steel. Tungsten steel has extremely high hardness and wear resistance, which can effectively resist the friction and wear generated during the polishing process, significantly extend the service life of the plug, reduce the replacement frequency, and reduce production costs.

The above are specific embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
