[0002] In the automobile manufacturing industry, as part of the vehicle exterior decoration and functional components, the appearance quality of the luggage rack directly affects the appearance and user satisfaction of the whole vehicle. Especially for aluminum alloy material luggage rack, surface treatment process is particularly important.

[0003] In order to improve the texture and decoration effect of the luggage rack aluminum pipe, it is usually necessary to carry out wire drawing treatment on the surface to remove small pits, fine scratches and other defects that may occur in the production process, and to show the unique metal luster of aluminum alloy.

[0004] At present, in the surface wire drawing treatment of the luggage rack aluminum pipe, two methods are mainly used: steel wire brush wire drawing and nylon sand belt wire drawing. However, these two traditional methods have significant shortcomings:

[0005] Steel wire brush wire drawing: this method has poor treatment effect on the recess area of the luggage rack, because the steel wire brush is difficult to enter the recess for fine processing, resulting in unsatisfactory wire drawing effect and low efficiency. In addition, the steel wire brush is easy to wear out and needs to be replaced frequently, increasing the maintenance cost and time.

[0006] Nylon sand belt wire drawing: although nylon sand belt can provide good wire drawing effect, but in actual application, the problem of sand belt deviation often occurs, that is, the sand belt deviates from the predetermined path during work, which not only affects the consistency of the wire drawing lines, but also accelerates the excessive consumption of the local area of the sand belt, causing the service life of the sand belt to be shortened. At the same time, due to uneven consumption of the sand belt, the wire drawing quality difference between different products is large, which reduces the overall yield. INVENTION CONTENTS

DETAILED DESCRIPTION

[0034] The following is a specific embodiment of the utility model and further describes the technical method of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0035] As shown in Figs. 1-3 , the utility model provides an equipment for surface wire drawing of luggage rack, which comprises:

[0036] frame 100;

[0037] The main drive wheel 110 is installed on the frame 100 through the main shaft 120, and the driving mechanism is in driving connection with the main shaft 120 and is used for driving the main drive wheel 110 to rotate;

[0038] The driven wheel 130 is rotatably installed in the mounting seat 140 and is connected with the main drive wheel 110 through the sand belt 150;

[0039] The control cylinder 160 is installed on the frame 100 through the support 161, the cylinder shaft of the control cylinder 160 is connected with the mounting seat 140, and the driven wheel 130 is driven to move along the preset direction by the control cylinder 160 to adjust the tension of the sand belt 150.

[0040] In specific work, the position of the driven wheel 130 is adjusted by the control cylinder 160 to ensure that the nylon sand belt 150 is in a tension state, and then the main shaft 120 is driven to rotate by the driving mechanism, the main drive wheel 110 is driven to rotate by the main shaft 120, the rotating nylon sand belt 150 is in contact with the luggage rack to be drawn to generate friction, and finally the drawn line is formed, when the nylon sand belt 150 is consumed to the limit, the driving mechanism is stopped, and after a new sand belt 150 is replaced, the next working cycle is carried out.

[0041] In order to ensure that the sand belt 150 maintains appropriate tension during work, prevents it from deviating or relaxing, the utility model adopts a unique tensioning mechanism, specifically, the driven wheel 130 is installed in a mounting seat 140 which can move along a preset path, the cylinder shaft of the control cylinder 160 is connected with the mounting seat 140, and the driven wheel 130 is driven to move along the predetermined direction by accurately controlling the extension and retraction of the cylinder shaft of the control cylinder 160, when the tension of the sand belt 150 needs to be increased, the control cylinder 160 is extended, and the driven wheel 130 is moved away from the main drive wheel 110, on the contrary, if the sand belt 150 needs to be relaxed, the control cylinder 160 is retracted, and the driven wheel 130 is close to the main drive wheel 110.

[0042] This way of adjusting the tension of the nylon sand belt 150 has at least the following advantages:

[0043] 1. Improve the drawing quality: by controlling the position of the driven wheel 130 through the control cylinder, the sand belt 150 can maintain uniform tension throughout the work process, avoiding the problem of inconsistent drawing lines caused by the deviation or uneven consumption of the sand belt 150 in the traditional method, thereby significantly improving the drawing quality and consistency.

[0044] 2. Improved production efficiency: The improved tensioning mechanism makes the replacement of the sanding belt 150 simpler and faster, reducing downtime. At the same time, the stable tension of the sanding belt 150 helps to extend its service life, reduce consumable costs, and thus improve overall production efficiency.

[0045] Preferably, the mounting base 140 has adjustment grooves on both sides, and the follower wheel 130 has a mounting shaft 131. The mounting shaft 131 passes through the adjustment groove. One end of the mounting shaft 131 is a fixed end, which is fixed to the mounting base 140 by a pin 1311. The other end of the mounting shaft 131 is an adjustment end and is provided with a fine-tuning component 170.

[0046] Specifically, the fine-tuning component 170 consists of an upper adjusting screw 171 and a lower adjusting screw 172. The lower adjusting screw 172 is screwed upward from the bottom of the mounting base 140 into the adjusting groove and abuts against the lower end face of the mounting shaft 131. The upper adjusting screw 171 is located on the outside of the mounting base 140 and abuts against the upper end face of the mounting shaft 131. By turning the upper adjusting screw 171 and the lower adjusting screw 172, the up and down position of the adjusting end of the mounting shaft 131 of the follower wheel 130 can be adjusted, thereby achieving the purpose of manually fine-tuning the tension of the sanding belt 150.

[0047] Since the fixed end of the mounting shaft 131 is fixed on the mounting base 140, the adjustment end of the mounting shaft 131 can only be adjusted up and down by the fine adjustment component 170. At this time, the position of the mounting shaft 131 will be deflected, which will drive the position of the follower wheel 130 to change, thereby realizing the adjustment of the tension of the sanding belt 150.

[0048] It should be noted that although fine-tuning the mounting shaft 131 may cause the position of the follower wheel 130 to become skewed, as long as the sanding belt 150 does not deviate, the sanding belt 150 can still work normally and complete the wire-pulling operation on the luggage rack.

[0049] The automatic, wide-range adjustment of the abrasive belt 150 is achieved by controlling the cylinder 160, ensuring the basic tension of the belt. The fine-tuning component 170 allows the operator to make fine manual adjustments to achieve the optimal tension. This dual adjustment mechanism can more accurately control the tension of the abrasive belt 150, ensuring the consistency and stability of the wire drawing process.

[0050] Preferably, the drive mechanism includes a motor 180, which is fixed to the side of the frame 100 by a motor mounting plate 181.

[0051] Preferably, it also includes a synchronous belt 190. The motor 180 is connected to the main shaft 120 through the synchronous belt 190. The rotation of the motor 180 drives the synchronous belt 190 to rotate, thereby realizing the rotation of the main shaft 120.

[0052] Preferably, the main shaft fixing base 121 is connected with the frame 100, the main shaft 120 passes through the main shaft fixing base 121, and the main shaft fixing base 121 not only provides a stable basis for supporting the main shaft 120, but also ensures that the main shaft 120 has sufficient rigidity and radial and axial bearing capacity during rotation.

[0053] Preferably, the main shaft mounting plate 122 is arranged between the main shaft fixing base 121 and the frame 100, and the main shaft fixing base 121, the main shaft mounting plate 122 and the frame 100 are connected through fasteners, so that the stability of the overall structure is enhanced.

[0054] Preferably, bearings are arranged between the main shaft 120 and the main shaft fixing base 121, in this embodiment, the bearings are combined support of the sealed deep groove ball bearing 123 and the angular contact ball bearing 124, so that the main shaft 120 has sufficient rigidity and bearing capacity during rotation, the jumping amplitude is reduced, and reliable mechanical support is provided for high-quality wire drawing operation.
