Description

Technical Field

[0001] This application relates to the technical field of workpiece processing, and in particular to a deburring mechanism for metal processing. Background Technology

[0002] In the field of metal processing, whether it's machinery manufacturing, automotive parts processing, or high-end manufacturing industries such as aerospace, the machining precision and surface quality of metal parts are crucial. Burrs, as an unavoidable product in the metal processing process, seriously affect the performance of parts, assembly accuracy, and the overall quality of the product.

[0003] Deburring is an essential and crucial step in metal processing. Metal parts with burrs may not fit tightly during assembly, leading to decreased assembly accuracy and consequently affecting the stability and reliability of the entire equipment. For example, in the manufacturing of automotive sheet metal parts, if burrs are not completely removed, insufficient assembly tightness may result in problems with the subsequent operation of the parts.

[0004] Existing simple deburring operations mostly involve workers using handheld angle grinders. During operation, the angle grinder throws the removed burrs outwards, potentially causing injury to the worker. Furthermore, due to the high speed of the angle grinder, its operation requires experience; for inexperienced workers, this poses a significant risk, and improper operation can easily lead to accidental injury. Therefore, to address these problems, this application provides a metal processing deburring mechanism. Utility Model Content

[0005] To address the aforementioned problems, this application provides a metal processing deburring mechanism.

[0006] This application provides a metal processing deburring mechanism that uses an angle grinder for deburring operations. The angle grinder has a metal part clamping structure on its side and is mounted externally using a fixing mechanism. Its angle and height are adjustable.

[0007] The clamping structure includes a sliding bar with a height-adjustable pressure plate above it. The pressure plate and the sliding bar work together to clamp the metal part. The clamping structure is mounted on a guide rail to achieve horizontal sliding and to grind different positions of the burr surface.

[0008] By modifying the existing angle grinder and clamping structure, fixing the position of the angle grinder, and allowing the clamping structure to move in a fixed direction, the learning curve is reduced, and the convenience of deburring and polishing operations can be effectively improved.

[0009] Preferably, the clamping structure has at least two sliding bars.

[0010] Preferably, the pressure plate is disposed between the sliding strip and the horizontal section of the upper bracket, and a handle is rotatably connected to the middle position of the pressure plate. The handle and the upper bracket are threaded together. Guide rods are also fixedly connected to both sides of the pressure plate and are slidably embedded in the upper bracket.

[0011] Preferably, a plurality of rubber pads are evenly distributed on the lower end surface of the pressure plate.

[0012] Preferably, each of the sliding bars is provided with a guide rail below it, and the slider and the sliding bar are fixedly connected by bolts.

[0013] Preferably, the fixing mechanism includes a telescopic structure and a clamp welded to the end of the telescopic structure. The clamp has an opening on one side, and the opening is locked with bolts. The clamp is fitted onto the outside of the angle grinder.

[0014] Preferably, the telescopic structure includes a sleeve and an inner rod that slide against each other, and the sleeve and the inner rod are locked in position by fastening bolts threaded on the sleeve. A fixing plate is vertically welded to the top of the inner rod, and the inner rod is installed and fixed to the external structure through the fixing plate.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] By modifying the existing angle grinder and clamping structure, fixing the position of the angle grinder, and allowing the clamping structure to move in a fixed direction, the learning curve is reduced, and the convenience of deburring and polishing operations can be effectively improved.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0022] Example 1:

[0023] A metal processing deburring mechanism, as described in the reference Figure 1 - Figure 3 The angle grinder 1 is used for deburring. The angle grinder 1 has a metal clamping structure on its side. The angle grinder 1 is mounted on the outside using a fixing mechanism 2. Its angle and height are adjustable.

[0024] The clamping structure includes sliding bars 8, and at least two sliding bars 8 are provided in the clamping structure.

[0025] An adjustable pressure plate 5 is installed above the sliding bar 8. The pressure plate 5 and the sliding bar 8 cooperate to clamp the metal part. The pressure plate 5 is located between the horizontal section of the sliding bar 8 and the upper bracket 4. A handle 6 is rotatably connected to the middle of the pressure plate 5. The handle 6 is threadedly connected to the upper bracket 4. Guide rods 7 are also fixedly connected to both sides of the pressure plate 5. The guide rods 7 are slidably embedded in the upper bracket 4. Several rubber pads 51 are evenly distributed on the lower end surface of the pressure plate 5. A guide rail 3 is installed below each sliding bar 8. The slider slidably embedded in the guide rail 3 is bolted to the sliding bar 8.

[0026] The clamping structure is mounted on the guide rail 3 to achieve horizontal sliding and grind different positions of the burr surface. The fixing mechanism 2 includes a telescopic structure and a clamp 21 welded to the end of the telescopic structure. The clamp 21 has an opening on one side, which is locked with bolts. The clamp 21 is sleeved on the outside of the angle grinder 1. The tightness adjustment of the clamp 21 can both bind the angle grinder 1 and adjust the angle of the angle grinder 1. The telescopic structure includes a sleeve 22 and an inner rod 23 that slide against each other. The sleeve 22 and the inner rod 23 are locked in position by a fastening bolt 221 threaded on the sleeve 22. A fixing plate 24 is vertically welded to the top of the inner rod 23, and the inner rod 23 is fixed to the external structure through the fixing plate 24.

[0027] The metal part to be processed can be a sheet metal part, a thick metal plate, or a tubular metal part, as long as its size is suitable for the clamping structure of this application and the surface to be processed is flat. Its X-axis dimension cannot exceed 1 / 3 of the top view area of ​​this application. If it exceeds this, there may be flatness problems. The Y-axis dimension can be selected according to the specific length, and the appropriate number of sliding bars 8 and guide rails 3 can be selected to ensure that there is no bending in the Y-axis direction.

[0028] Taking sheet metal parts as an example, during processing, first, rotate the handle 6 counterclockwise to raise the pressure plate 5 to a position where its height and that of the sliding strip 8 are greater than the thickness of the sheet metal part. Then, place the sheet metal on the sliding strip 8, and rotate the handle 6 clockwise to lower the pressure plate 5, ensuring that each rubber pad 51 is pressed firmly against the upper surface of the sheet metal. During the pressing process, it is also necessary to ensure that the straight line where the burr edge of the sheet metal is located coincides with the grinding disc of the angle grinder 1, so as to ensure the smooth progress of subsequent grinding. After the sheet metal is installed, adjust the height of the angle grinder 1 by adjusting the degree of overlap between the sleeve 22 and the inner rod 23. If an angle is required, loosen the clamp 21, rotate the angle grinder 1 to obtain the appropriate angle, and then tighten it. Turn on the angle grinder 1, and then simply push the upper bracket 4 from right to left. The angle grinder 1 will clean the burrs when it comes into contact with them. Depending on the actual situation, if necessary, multiple angle grinders 1 can be set up using the fixed mechanism 2. The grit of each angle grinder 1 can be increased from low to high. While removing burrs, it can also complete the polishing operation, further improving the convenience of processing.
