Description

Technical Field

[0001] This utility model relates to the field of grinding and processing equipment technology, and in particular to a reversible metal grinding device. Background Technology

[0002] Grinding is a surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. Metal parts also need to be ground during processing, and they also need to be fixed by fixtures during the processing.

[0003] In the current grinding process of metal parts, due to the large overall volume of the metal parts and the presence of multiple grinding points on the end face, the end face of the metal parts is not a uniform plane. Therefore, the processing position of the grinding equipment needs to be manually adjusted during the processing. Manual adjustment not only affects the processing accuracy but also leads to a long grinding process. The metal parts are prone to deformation during the clamping and grinding process, which reduces the automation effect of the processing of metal parts. This is not conducive to the comprehensive and high-quality grinding of metal parts and results in low grinding efficiency. Utility Model Content

[0023] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, this application proposes a flip-up metal grinding device, which includes a loading mechanism 1 and a grinding mechanism 2 placed below the loading mechanism 1. The loading mechanism 1 is used to place the workpiece and drive the workpiece to rotate 180°, so that the workpiece is rotated to the top of the output end of the grinding mechanism 2. The grinding mechanism 2 simultaneously grinds several processing points on the workpiece, effectively improving work efficiency. The workpiece loading and grinding are carried out separately, effectively improving the safety of the loading process.

[0025] like Figure 1 As shown, the loading mechanism 1 includes two sets of opposing supports 11, with a rotatable mounting plate 12 positioned between the supports 11. One end face of the mounting plate 12 is equipped with a clamping member for fixing the workpiece. One end of the mounting plate 12 is connected to a rotary drive 13, which drives the mounting plate 12 and the workpiece clamped on it to rotate synchronously. The end face of the mounting plate 12 with the clamping member faces upwards for workpiece loading, and then the rotary drive 13 drives the mounting plate 12 and the workpiece to rotate synchronously by 180° for workpiece grinding. Preferably, in this embodiment, the rotary drive 13 can be a rotary motor, a motor gear assembly, or other similar structure; no specific limitation is made here.

[0026] like Figure 1As shown, the clamping components include end clamps 14 for fixing the ends of the workpiece and middle clamps 15 for fixing the middle section of the workpiece. The end clamps 14 and the middle clamps 15 cooperate with each other to restrict the entire workpiece on the mounting plate 12 and prevent the workpiece from deforming during the grinding process. In this embodiment, four sets of end clamps 14 are arranged on the mounting plate 12 to support the four corners of the workpiece; several sets of middle clamps 15 are arranged at intervals on the mounting plate 12 to adaptively support the middle section of the workpiece.

[0027] like Figure 1-2 As shown, the end clamping member 14 includes a first support portion and a first pressing portion located on one side of the first support portion. The first support portion is used to support the end of the workpiece, and the first pressing portion is correspondingly pressed onto the upper part of the end of the workpiece. The first support portion includes a first bracket 141, and a positioning plate 142 is screwed onto the upper part of the first bracket 141 by screws 143. The positioning plate 142 has protruding positioning pins 144, which can be inserted into the positioning holes at the end of the workpiece. Preferably, a plurality of mounting holes are provided at intervals on the upper end of the first bracket 141. The positioning plate 142 can be screwed into different mounting holes by screws 143 to adjust the position of the positioning pins 144, which can meet the positioning support of workpieces of different sizes, is easy to adjust, and has strong adaptability. The first pressing part includes a first lifting cylinder 145. The output end of the first lifting cylinder 145 faces upward and the push rod end is rotatably connected to a connecting rod 146. The upper end of the connecting rod 146 is equipped with a first pressing rod 147. The middle section of the connecting rod 146 is rotatably connected to a first connecting rod 148. The other end of the first connecting rod 148 is rotatably connected to the side of the first lifting cylinder 145 near the first support part. Preferably, a flat pressure plate is provided at the end of the first pressing rod 147 away from the connecting rod 146 to increase the pressing area of ​​the first pressing rod 147 acting on the workpiece and prevent the pressing force from being too concentrated, causing damage to the exterior of the workpiece.

[0028] like Figure 1 and 3As shown, the central clamping member 15 includes a second support portion and a second pressing portion located on one side of the second support portion. The second support portion supports the middle section of the workpiece, and the second pressing portion presses down on the middle section of the workpiece. The second support portion includes a second bracket 151, and a floating support platform 152 is disposed on the upper part of the second bracket 151. A spring (not shown) is provided between the floating support platform 152 and the second bracket 151. The spring allows the floating support platform 152 to adaptively adjust its height according to the shape of the corresponding position of the workpiece, meeting the support requirements of different situations and providing high flexibility. The second pressing portion includes a second lifting cylinder 153. The output end of the second lifting cylinder 153 faces upward, and the push rod end is rotatably connected to a second pressing rod 154. The middle section of the second pressing rod 154 is rotatably connected to a second connecting rod 155, and the other end of the second connecting rod 155 is rotatably connected to the side of the second lifting cylinder 153 near the second support portion.

[0029] like Figure 1 and 4 As shown, the grinding mechanism 2 includes several grinding components 22 and a first transverse module 21 that drives the grinding components 22 to move laterally. The first transverse module 21 moves the grinding components 22 to below the mounting plate 12 to grind the clamped workpiece. After grinding, the first transverse module 21 moves the grinding components 22 back to their original position, providing clearance for the flipping of the mounting plate 12 and preventing interference between the mounting plate 12 and the grinding components 22 during the flipping process. Preferably, the several grinding components 22 are connected to the moving end of the first transverse module 21 via a connecting plate. The arrangement of the grinding components 22 is arranged according to the grinding points of the workpiece and can be adaptively adjusted according to the grinding requirements of the workpiece; no limitation is made here. The first transverse module 21 moves the several grinding components 22 synchronously to below the workpiece, allowing for simultaneous grinding of multiple points and effectively improving work efficiency.

[0030] like Figure 1 and 4 As shown, the grinding component 22 includes a grinding bracket 221, on which a liftable grinding machine and a first lifting module 222 for driving the grinding machine to rise and fall are mounted. The grinding machine includes a grinding head 223 and a rotary motor 224 for driving the grinding head 223 to rotate. When the grinding component 22 is positioned below the grinding point of the workpiece, the first lifting module 222 drives the grinding machine to rise, so that the grinding head and the workpiece are in contact. The rotary motor 224 drives the grinding head 223 to rotate, thus performing grinding.

[0031] In this embodiment, both the first transverse module 21 and the first lifting module 222 are composed of a motor, a lead screw, and a slide rail assembly. In other embodiments, components such as cylinders and slide rails may be used, and no specific limitation is made here.
