Description

Technical Field

[0001] The present application relates to the technical field of curved stamping plate parts, and in particular to a device for grinding weld points of curved stamping plate parts. Background Art

[0002] Automotive stamping parts with curved structures play a vital role in automobile manufacturing. They not only affect the aesthetic appearance of the car, but are also directly related to the vehicle's safety, aerodynamic performance, and manufacturing costs. Some common automotive stamping parts with curved structures and their characteristics include: fenders, which are located on both sides of the car body, covering the wheels, and have complex curved shapes to match the overall lines of the car body; hood panels, which are the outer covering of the engine hood, are usually made of lightweight, high-strength materials and have a large curved surface area to provide good visual effects and aerodynamic performance. And also includes curved stamping parts such as front door panels, rear door panels, front and rear wheel arches, etc., which have a high proportion in the composition of automobile structures.

[0003] Due to the complexity of automobile structures, after a single piece of automobile stamping parts with curved structures is stamped, it is necessary to arrange several smaller components on the stamping parts, such as assembly plates. In order to ensure the integrity, components such as assembly plates are usually welded to the stamping parts, including continuous welding along the side of the assembly plate, or spot welding when the plate thickness is thin. Usually, after welding is completed, welding slag will inevitably remain at the welding point, and in order to ensure the smoothness of the surface, the weld needs to be cleaned.

[0004] In order to reduce the overall weight of the car, the plate components used are usually thinner on the basis of ensuring strength. If a handheld grinder is used to remove welding slag, it is very easy to cause pits on the surface of stamping parts and other components under the influence of manual instability. In more serious cases, it may cause the plate to be worn through. Therefore, more methods such as the instructions are used. Figure 3-4 The shovel body shown in the figure is used for shoveling, and during the shoveling process, the reciprocating movement of the shovel body causes the end of the shovel body to contact the surface of the assembly plate, such as Figure 4 As shown, this will also cause scratches on the surface of the assembly plate or stamping parts. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a device for grinding weld points of curved stamped sheet metal parts, which can effectively buffer the contact between the cutting edge of the grinding shovel and the side wall of the assembly plate, thereby reducing the contact impact force between the cutting edge and the side wall of the assembly plate, and thus solving the problem of contact scratches on the side wall of the assembly plate or the surface of the stamped part.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a device for grinding weld points of curved stamped sheet metal parts, the grinding device including a grinding shovel with one end set as a cutting edge, characterized in that an anti-collision buffer component is provided at one end of the grinding shovel located at the cutting edge, and the outside of the buffer component on the cutting edge is a grinding portion.

[0007] Preferably, steps are symmetrically provided on both sides of the cutting edge, and the buffer component is a buffer sleeve fixedly assembled on the steps, and the side edges of the buffer sleeve extend out of the cutting edge.

[0008] Preferably, a limiting notch is provided on the grinding portion to limit the contact between the cutting edge and the welding point.

[0009] Preferably, the grinding shovel is divided into a fixed section and a hinged section which are hinged to each other, and the fixed section and the hinged section can be hinged and locked.

[0010] The beneficial effect of the present application is that the weld grinding device is provided with an anti-collision buffer component at one end of the grinding shovel located at the cutting edge, which can effectively buffer the contact between the cutting edge of the grinding shovel and the side wall of the assembly plate, thereby reducing the contact impact force between the cutting edge and the side wall of the assembly plate, and then solving the problem of contact scratches on the side wall of the assembly plate or the surface of the stamping part, ensuring the plate surface quality of the stamping part, and at the same time improving the operability of welding slag removal.

[0026] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Refer to the attached Figures 1 to 13 The device for grinding weld points of curved stamped plate shown in FIG. 1 includes a grinding shovel 1 with a cutting edge 1a at one end. When performing a welding slag cleaning operation at a welding point, as shown in FIG. Figure 3-4 As shown, the operator holds the tail end of the grinding shovel 1 and reciprocates to make the cutting edge 1a of the grinding shovel 1 contact the welding spot, thereby removing the welding slag remaining at the welding spot. In order to solve the problem of scratching the side wall of the assembly plate due to the impact of the cutting edge 1a of the grinding shovel 1 on the side wall of the assembly plate, as shown in FIG. Figure 6-8 As shown, a buffering member is installed at one end of the sharpening blade 1 at the cutting edge 1a to prevent impact. The outer portion of the buffering member on the cutting edge 1a forms a sharpening portion 1b. This buffering member effectively cushions the contact between the sharpening blade 1a and the sidewall of the mounting plate, reducing the impact force and thus preventing scratches on the mounting plate. The sharpening portion 1b extends beyond the buffering member to ensure an effective sharpening width for the cutting edge 1a.

[0028] Further, if Figure 5-8As shown, steps 1c are symmetrically formed on either side of the cutting edge 1a. The buffer member is a buffer sleeve 2 fixedly mounted on the step 1c. The buffer sleeve 2 is preferably made of rubber. During the aforementioned welding slag removal operation, when the cutting edge 1a moves toward and contacts the side wall of the assembly plate, the buffer sleeves 2 on either side of the cutting edge 1a contact the side wall of the assembly plate, thereby cushioning the impact of the cutting edge 1a, thereby reducing and eliminating contact scratches on the side wall of the assembly plate. The side edges of the buffer sleeve 2 extend outside the cutting edge 1a to prevent scratches on the cutting edge 1a caused by the synchronous contact of the buffer sleeve 2 with the side wall of the assembly plate.

[0029] Since the side of the grinding part 1b for removing welding slag is a straight line structure, during the contact and removal process with welding slag, Figure 9 There will be left and right deviation in the direction of the arrow shown in the figure, which will cause the grinding shovel 1 to separate from the welding point. Therefore, in order to solve this problem, Figure 10 As shown, a limiting notch 1d is provided on the grinding portion 1b to limit the contact between the cutting edge 1a and the welding point. During the grinding contact process, the limiting notch 1d contacts the welding point, which can achieve a limiting effect on the entire grinding shovel 1, thereby improving the effectiveness of removing welding slag. At the same time, after the welding slag is embedded in the limiting notch 1d, it can also be removed by Figure 11 The left-right flipping indicated by the arrows realizes the prying and removing operation of the welding slag, further improving the operability of the grinding shovel 1.

[0030] In the process of cleaning the welding slag on the surface of the stamping part with curved surface structure, the cutting edge 1a of the grinding shovel 1 cannot contact the welding part after it approaches the stamping part surface due to the curved surface structure. Figure 12 As shown in the state, to solve this problem, Figure 13 As shown, the sharpening shovel 1 is divided into a fixed section 11 and an articulated section 12 that are hinged to each other, and the fixed section 11 and the articulated section 12 can be hinged and locked. A lockable articulation screw 3 is preferably provided at the hinge point between the two. The articulation angle of the fixed section 11 and the articulated section 12 is adjusted according to the surface structure of the stamping part. When the cutting edge 1a of the front end of the articulated section 12 contacts the welding slag, the fixed section 11 is kept away from the stamping part surface, thereby facilitating the application of force when holding the fixed section 11 for removal.

[0031] The principle of this application is as follows: when performing the welding point grinding operation on a curved stamping plate, first connect the cutting edge 1a at the front end of the hinged section 12 to the welding point, and adjust the hinge angle of the fixed section 11 and the hinged section 12 according to the surface structure of the stamping part, so that the cutting edge 1a at the front end of the hinged section 12 is in contact with the welding slag, and the fixed section 11 is moved away from the surface of the stamping part. Then, hold the fixed section 11 and apply a reciprocating driving force to the grinding shovel 1 as a whole, so that the limiting recess 1d provided on the grinding part 1b is in contact with the welding point, and the welding slag at the welding point is scraped off. At the same time, after the welding slag is embedded in the limiting recess 1d, the welding slag can be pried and removed by flipping it left and right, thereby further improving the operability of the grinding shovel 1. When the sharpening shovel 1 is in operation and slips off the welding point, the buffer sleeves 2 on both sides of the cutting edge 1a contact the side wall of the assembly plate, or contact the surface of the stamping part, thereby buffering the impact contact of the cutting edge 1a, thereby reducing and eliminating the problem of contact scratches on the side wall of the assembly plate.

[0032] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
