[0005] 2. It takes a long time to fix parts with bolts, and the work efficiency is not high.

[0006] The technical solution of this utility model:

[0007] An anodizing fixture for flat-plate parts comprises a copper hook 1, a tightening knob 2, a spindle straight rod 3, a disc 5, and a fixing ring 6. The end of the copper hook 1 is connected to the spindle straight rod 3. An even number of discs 5 are arranged on the spindle straight rod 3. Every two adjacent discs 5 are arranged opposite to each other from top to bottom along the spindle straight rod 3. Fixing rings 6 are respectively arranged at the upper and lower ends of each disc 5 to limit and fix the disc 5. A plurality of clamping parts are arranged along the circumference of the disc 5. A groove is arranged at the end of the clamping part for clamping the two ends of the flat-plate parts. A clamping sheet is arranged in the copper hook 1. The clamping sheet is close to the bending part of the copper hook. A tightening knob 2 is arranged on the bending part of the copper hook 1. The end of the tightening knob 2 contacts the clamping sheet.

[0008] Furthermore, the end of the copper hook 1 is connected to the main shaft straight rod 3 through a bolt 4.

[0009] Furthermore, the fixing ring 6 is a clamp structure with an opening, and its opening is connected by a fastening stud 7 to fix the fixing ring 6 on the main shaft straight rod 3.

[0010] Furthermore, the copper hook 1 is a 6 mm thick copper plate.

[0011] Furthermore, the spindle straight rod 3 is a Φ60mm aluminum rod, and both sides of the upper end are milled into flat surfaces to facilitate good contact and connection with the copper plate.

[0012] Furthermore, the number of the disks 5 is 2.

[0013] Furthermore, the spindle straight rod 3 and the disc 5 are overfitted.

[0014] Beneficial effects of the utility model: The utility model has the following advantages:

[0015] 1. The parts are clamped by the grooves on the disc, which reduces the contact area, eliminates the fixture marks caused by the traditional clamping method, and improves the surface quality of the parts.

[0016] 2. The fixture is easy to operate, has a large number of clamping parts, and a short clamping time. Each fixture can be installed with multiple discs, and the discs can be flexibly adjusted according to the size of the parts, which improves production efficiency.

[0017] 3. Titanium is not easily oxidized, has good strength and toughness, and can ensure sufficient support force by using fixing rings and fastening studs. It is firmly clamped, has good conductivity, and the performance of the oxide film of parts is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] See also Figure 1-7 The utility model proposes an anodizing fixture for flat plate parts, including a copper hook 1, a tightening knob 2, a spindle straight rod 3, a bolt 4, a disc 5, a fixing ring 6, and a tightening stud 7; the copper hook 1 is a 6mm thick copper plate with good conductivity, the bolt 4 is made of high-quality stainless steel with good corrosion resistance, the spindle straight rod 3 is a Φ60mm aluminum rod, and the upper ends are milled into planes on both sides, the copper hook 1 is connected to the spindle straight rod 3 by two groups of bolts 4, and the tightening knob 2 is used to strengthen the connection between the copper hook 1 and the conductive rod. When the copper hook 1 is hung on the conductive rod, the tightening knob is turned to tighten the copper hook 1. 2, so that its end contacts the pressing piece, and the pressing piece presses the conductive rod, so that the copper hook 1 is in more firm contact with the conductive rod; the spindle straight rod 3 and the disc 5 are over-matched, and the spindle straight rod 2 fixes a disc 5 on the spindle straight rod through two fixing rings 6, and each fixing ring is equipped with a fastening stud 7. The fixture can install multiple discs according to actual production, and the position of the disc can be adjusted according to the size of the part. The disc 5 is made of titanium alloy, and there are 18 grooves on the top of the disc 5, which are V-shaped.
