Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically a positioning fixture for polishing metal products. Background Technology

[0002] Currently, people have increasingly higher requirements for finished metal products. They require metal products to not only meet the requirements of use, but also meet people's aesthetic requirements. However, regardless of whether they are manufactured by pressing or casting, the surface of metal products will inevitably have some uneven flaws. Some areas with large differences will affect the performance of the product and also affect the appearance of the finished product. Therefore, polishing has become an indispensable step in the manufacturing process of metal products.

[0003] In the polishing of existing metal products, for stepped circular products, the processing fixture can only position and process a single workpiece at a time, thus reducing the processing efficiency of metal products.

[0004] Therefore, we propose a positioning fixture for polishing metal products to solve the above problems. Utility Model Content

[0023] Example

[0024] like Figures 1-3As shown in the figure, a positioning fixture for polishing metal products according to one embodiment of the present invention includes a base plate 1, with columns 2 embedded around the base plate 1, and a carrier plate 3 fixedly installed on the top of the columns 2. Placement bosses 4 are evenly distributed on the carrier plate 3, and clamping arms 5 are hinged to both sides of the placement bosses 4 on the carrier plate 3. Adjusting bolts 6 are installed at the top of the clamping arms 5, and clamping plates 7 are fastened to them by the adjusting bolts 6. Lifting cylinders 8 are installed at both ends of the base plate 1, and lifting blocks 9 are fixedly connected to the output ends of the lifting cylinders 8. The lifting blocks 9 and the clamping arms 5... The bottom end is hinged together, and at least four placement bosses 4 are distributed on the carrier plate 3. Each boss has a clamping arm 5 hinged to both sides. The upper part of the clamping arm 5 is connected to the clamping plate 7 through the adjusting bolt 6, and the lower part is connected to the lifting cylinder 8 through the lifting block 9. When the lifting cylinder 8 moves upward, it can drive the clamping plates 7 on both sides of the boss to unfold outward. Conversely, when the lifting cylinder 8 moves downward, it can drive the clamping plates 7 on both sides of the boss to press inward, thereby clamping and fixing the stepped circular workpiece on the boss. This achieves a multi-station clamping and positioning effect, avoids multiple clamping, and improves processing efficiency.

[0025] like Figure 1 As shown, in some embodiments, a solenoid valve 10 is installed on the base plate 1, and the solenoid valve 10 is connected to the lifting cylinder 8 through a hose. The solenoid valve 10 is an integrated electrical control element that can convert signals into actions and control fluid flow. In the pneumatic system, the solenoid valve 10 controls the on / off state of the cylinder to realize the conversion of air flow. That is, by controlling the energization and de-energization of the solenoid valve 10, the direction of gas flow can be changed, thereby controlling the piston of the cylinder to reciprocate.

[0026] like Figure 1 As shown, in some embodiments, the carrier plate 3 has openings 11 on both sides of the placement boss 4, and the clamping arm 5 is hinged to the opening 11 by a pin. The opening 11 is designed to avoid obstruction, so as to facilitate the installation of the clamping arm 5 and avoid structural interference.

[0027] like Figure 1 As shown, in some embodiments, the clamping plate 7 is L-shaped and located above the carrier plate 3. When the lifting cylinder 8 moves upward, it can drive the clamping plates 7 on both sides of the boss to unfold outward. Conversely, when the lifting cylinder 8 moves downward, it can drive the clamping plates 7 on both sides of the boss to press inward, thereby clamping and fixing the stepped circular workpiece on the boss.

[0028] like Figure 1 As shown, in some embodiments, the clamping plate 7 is provided with a strip hole 12, and the adjusting bolt 6 is installed in the strip hole 12 to make the clamping plate 7 and the clamping arm 5 securely connected. According to the on-site processing conditions, the relative position height of the clamping plate 7 can be adjusted up and down by loosening the adjusting bolt 6, so as to adapt to the clamping and fixing of stepped circular workpieces of different thicknesses.

[0029] like Figure 2 As shown, in some embodiments, the lifting block 9 is provided with ear seats 13 on both sides, and the ear seats 13 are hinged to the clamping arm 5 by a pin. The ear seats 13 are an assembly structure used to be hinged to the clamping arm 5 by a pin.

[0030] In use, at least four mounting bosses 4 are distributed on the carrier plate 3, and each boss has a clamping arm 5 hinged to both sides. The upper part of the clamping arm 5 is connected to the clamping plate 7 through the adjusting bolt 6, and the lower part is connected to the lifting cylinder 8 through the lifting block 9. When the lifting cylinder 8 moves upward, it can drive the clamping plates 7 on both sides of the boss to unfold outward. Conversely, when the lifting cylinder 8 moves downward, it can drive the clamping plates 7 on both sides of the boss to press inward, thereby clamping and fixing the stepped circular workpiece on the boss. This achieves a multi-station clamping and positioning effect, avoids multiple clamping, and improves processing efficiency.

[0031] In summary, at least four mounting bosses 4 are distributed on the carrier plate 3, and each boss has a clamping arm 5 hinged to both sides. The upper part of the clamping arm 5 is connected to a clamping plate 7 through an adjusting bolt 6, and the lower part is connected to a lifting cylinder 8 through a lifting block 9. When the lifting cylinder 8 moves upward, it can drive the clamping plates 7 on both sides of the boss to unfold outward. Conversely, when the lifting cylinder 8 moves downward, it can drive the clamping plates 7 on both sides of the boss to press inward, thereby clamping and fixing the stepped circular workpiece on the boss. This achieves a multi-station clamping and positioning effect, avoids multiple clamping, and improves processing efficiency.
