Description

Technical Field

[0001] The utility model relates to the technical field of metal material grinding, in particular to a vehicle chassis grinding and repairing device. Background Art

[0002] As the saying goes, "a rotten car starts with a rotten bottom." The chassis of a car is close to the ground for a long time. Whether it is a wet road on a rainy day or a hot road on a sunny day, it will have more or less impact on the car chassis. Although technology is relatively advanced now, the chassis of every car is treated with rust prevention before leaving the factory. Under normal use, the chassis will not rust for more than ten years. However, it is well known that it is inevitable that the car will scrape the bottom during driving, especially for those cars with lower chassis. If the damaged part of the chassis is not handled in time after scraping the bottom, it will definitely rust over time.

[0003] In the prior art, before people perform anti-rust spraying on damaged parts of the chassis, in order to ensure the quality of the spraying, the damaged parts are usually polished first. When polishing, the vehicle needs to be lifted by a lifting device first, and then the damaged parts are polished by the staff. The processing efficiency is low and the risk factor is high. In addition, lifting the vehicle for a long time will also consume more electricity, thereby greatly increasing the maintenance cost. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a vehicle chassis grinding and repair device, which solves the technical problems in the prior art that the vehicle needs to be lifted up when grinding the vehicle chassis, resulting in low processing efficiency and high risk factor.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] according to Figure 1-Figure 4 As shown, a vehicle chassis grinding and repairing device comprises an installation straight plate 1, a chassis grinding mechanism 2 is arranged on the upper end of the installation straight plate 1, and a repair auxiliary mechanism 3 is movably installed on the lower end of the installation straight plate 1. When the staff is grinding the vehicle chassis, the installation straight plate 1 will move to the bottom of the vehicle under the action of the chassis grinding mechanism 2, and then the chassis grinding mechanism 2 will quickly grind the damaged part of the chassis.

[0022] Specifically, the chassis grinding mechanism 2 includes a telescopic cylinder 201 fixedly mounted on the upper end of the mounting straight plate 1, a grinding platform 202 is fixedly mounted on the upper end of the telescopic cylinder 201, a grinding ball 203 is movably mounted on the upper end of the grinding platform 202, a grinding motor 204 for driving the grinding ball 203 to rotate is fixedly mounted on the lower end of the grinding platform 202, a protective round cover 205 is movably mounted on the upper end of the grinding platform 202, and the protective round cover 205 is movably sleeved on the outside of the rotating shaft of the grinding ball 203, and the lower surface of the protective round cover 205 is in contact with the upper surface of the grinding platform 202. A compression spring 206 is arranged between the surfaces, and the upper end of the compression spring 206 contacts with the bottom of the protective round cover 205. During grinding, the protective round cover 205 will always block the outside of the grinding ball 203 under the elastic force of the compression spring 206. A shooting component 207 is arranged inside the protective round cover 205. During grinding of the chassis, the grinding platform 202 will move upward under the action of the telescopic cylinder 201, so that the grinding ball 203 contacts with the damaged part. Next, the grinding ball 203 will rotate at high speed under the action of the grinding motor 204, so as to complete the grinding process.

[0023] Specifically, the maintenance auxiliary mechanism 3 includes a mounting bracket 301 fixedly mounted on the lower end of the mounting straight plate 1, a movable rotating wheel 302 and a driving motor for driving the movable rotating wheel 302 are movably mounted on the mounting bracket 301, a battery pack 303 is detachably mounted on the lower end of the mounting bracket 301, and the outer sleeve of the battery pack 303 is provided with a rubber cover. During the horizontal movement of the mounting straight plate 1 on the ground, the rubber cover can provide certain protection for the battery pack 303 to avoid damage to the battery pack 303. A supporting square column 304 is fixedly mounted on the upper end of the mounting straight plate 1, and a heat dissipation component 305 is provided on the upper end of the supporting square column 304. When the movable rotating wheel 302 rotates under the action of the driving motor, the device will move horizontally.

[0024] More specifically, the shooting component 207 includes a wireless camera that can be detachably installed inside the protective dome 205. A controller is provided at the lower end of the protective dome 205. Before the grinding process begins, the device will move horizontally under the car. During the movement, the wireless camera will shoot the car chassis and transmit the image to the staff's mobile phone in real time.

[0025] More specifically, the heat dissipation component 305 includes a micro motor fixedly mounted on the upper end of the supporting square column 304. The output end of the micro motor is transmission-connected to a blower fan blade. When the micro motor is powered on, the blower fan blade rotates at a high speed, thereby quickly dissipating the heat in the grinding area.

[0026] In this embodiment, when in use, the movable wheel 302 will rotate under the action of the driving motor. When the movable wheel 302 rotates, the device can move slowly under the chassis of the car. During the movement, the wireless camera inside the shooting component 207 will take real-time pictures of the chassis and wirelessly transmit the captured images to the staff's mobile phone, thereby facilitating the staff to quickly complete the inspection of the car chassis without jacking up the vehicle.

[0027] When the staff finds the damaged part from the picture, they will remotely control the movable wheel 302 to stop rotating, and then the device will stop below the damaged part. Next, the telescopic cylinder 201 will extend vertically upward to move the polishing platform 202 upward. When the polishing platform 202 moves upward, the polishing ball 203 will contact the damaged part of the chassis. Subsequently, the polishing ball 203 will rotate at high speed under the action of the polishing motor 204, thereby completing the polishing process of the damaged part.

[0028] Moreover, if Figure 2 As shown, initially the height of the protective hood 205 is higher than the height of the polishing ball 203, so when the polishing platform 202 moves upward, the protective hood 205 will contact the chassis of the car. Therefore, during the polishing process, the protective hood 205 will always block the outside of the polishing ball 203, thereby preventing the debris generated during the polishing process from splashing everywhere.

[0029] After the grinding is completed, the telescopic cylinder 201 will shrink downward to move the grinding platform 202 downward, so that the protective round cover 205 is out of contact with the car chassis. Then, the heat dissipation component 305 installed on the upper end of the supporting square column 304 will blow air to dissipate heat to the part that has just been grinded. After a certain period of time, the installation straight plate 1 will be moved out from under the car under the action of the movable wheel 302.

[0030] This embodiment, by providing a chassis grinding mechanism 2 and utilizing the cooperation between the shooting component 207 and the grinding ball 203, can help the staff quickly find the damaged parts of the chassis and perform grinding processing, without having to lift up the vehicle and then perform manual grinding, which can effectively improve the working efficiency of the chassis grinding processing and also avoid the occurrence of safety accidents; moreover, this embodiment, by providing a maintenance auxiliary mechanism 3 and utilizing the cooperation between the movable rotating wheel 302 and the heat dissipation component 305, can enable the device to move freely under the vehicle, and there is no need to lift the vehicle during the grinding process, which can reduce energy loss to a certain extent. In addition, the grinding parts of the chassis will automatically dissipate heat during the movement, which is convenient to use.

[0031] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
