Description

Technical Field

[0001] This utility model relates to the field of hanging fixture technology, and in particular to a hanging fixture for workpiece anodizing. Background Technology

[0002] Aluminum components are widely used in both military and civilian industries. For example, aluminum tubing is required in the manufacturing of military or civilian sights. However, aluminum components are easily corroded when exposed to air for extended periods. Therefore, anodizing is necessary to form a dense oxide film on the surface of the aluminum components, thereby improving their corrosion resistance and wear resistance. The aluminum component is made into an anode, and an oxide film is formed on its surface using an electrolytic method. This metal oxide film alters the surface state and properties, such as surface coloring, improved corrosion resistance, enhanced wear resistance, and increased hardness.

[0003] When aluminum tubes are placed on a hanger for anodizing, the hanger has multiple placement trays. Several aluminum tubes can be installed on the placement trays, and then the placement trays are fixed to the uprights or frames with bolts, so that the multiple placement trays are evenly distributed from top to bottom on the uprights. However, using bolts to fix the placement trays is a cumbersome operation, which reduces the fixing efficiency of the placement trays. Afterwards, workers need to remove the bolts one by one before the placement trays can be removed, which reduces the material cutting efficiency of the aluminum tubes. Moreover, the bolts may rust after long-term use, making installation and disassembly even more inconvenient. Utility Model Content

[0004] This utility model discloses a hanger for workpiece anodizing, which solves the problem of cumbersome operation and subsequent need for workers to disassemble the bolts one by one, which reduces the efficiency of aluminum tube cutting.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A workpiece anodizing fixture includes a vertical pole with a first fixing plate and a second fixing plate fixed on both sides, arranged in an alternating vertical arrangement. A sleeve is fitted onto the vertical pole, with the first and second fixing plates located inside the sleeve. A fixing ring is fixed to the outer side of the sleeve, and a set of symmetrically arranged suspension rods is fixed to the outer surface of the fixing ring, with the two opposing suspension rods arranged in a V-shape. Two symmetrically arranged connecting posts are fixed to the inner side of the sleeve, located between the first and second fixing plates. An insertion rod is fixed to the bottom of the connecting post, and a through hole for inserting the insertion rod is provided at the top of the second fixing plate. A support frame is fixed to the bottom of the vertical pole.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] After the aluminum tube is fitted onto two opposing suspension rods, the sleeve is then fitted onto the upright, positioning the connecting post between the first and second fixing plates. The sleeve is then rotated to position the connecting post between the first and second fixing plates, and the sleeve is moved downwards until the insertion rod is inserted into the perforation at the top of the second fixing plate, thus securing the sleeve. After securing the other sleeves using the same method, the upright can be placed in the designated position using the support frame, and the aluminum tube can be anodized. Once the anodizing is complete, the sleeve is simply moved upwards and rotated to remove the connecting post from between the first and second fixing plates, allowing the sleeve to be removed from the upright. This invention eliminates the need for bolts, improving the loading and unloading speed of the aluminum tubes and reducing the workload of the workers. Attached Figure Description

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a workpiece anodizing fixture, including a pole 1, with a first fixing plate 2 and a second fixing plate 3 fixed on both sides of the pole 1, the first fixing plate 2 and the second fixing plate 3 being staggered vertically; a sleeve 4 is fitted on the pole 1, the first fixing plate 2 and the second fixing plate 3 are both located inside the sleeve 4, a fixing ring 41 is fixed on the outer side of the sleeve 4, and a set of suspension rods 42 symmetrically distributed vertically are fixed on the outer ring surface of the fixing ring 41, the two vertically opposite suspension rods 42 are arranged in a figure-eight shape; two left-right symmetrical connecting columns 5 are fixed on the inner side of the sleeve 4, the connecting columns 5 are located between the first fixing plate 2 and the second fixing plate 3, the bottom of the connecting column 5 is fixed with an insertion rod 51, and the top of the second fixing plate 3 has a through hole for the insertion rod 51 to be inserted; a support frame 7 is fixed at the bottom of the pole 1.

[0015] like Figure 1 and Figure 2 As shown, a fixing rod 31 is fixed between the first fixing plate 2 and the second fixing plate 3. The two fixing rods 31, located at the same height, are staggered from left to right. The rods 31 located on the front of the upright 1 (with...) Figure 1 (As shown in the diagram) Fixing rod 31 is located on the right side of the top of fixing plate 3, and fixing rod 31 on the back of upright 1 is located on the left side of the top of fixing plate 3. The setting of fixing rod 31 can increase the firmness of fixing plate 2 and fixing plate 3, and can also limit the connection column 5. When the operator rotates sleeve 4, the two connection columns 5 can move accordingly. When the two connection columns 5 contact the two fixing rods 31 respectively, it means that the insertion rod 51 corresponds to the through hole at the top of fixing plate 3. At this time, sleeve 4 can be moved directly downward.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a short rod 43 is fixed to the bottom of the sleeve 4, and a connecting ring 44 located above the fixing ring 41 is fixed to the outside of the sleeve 4. When the insertion rod 51 is inserted into the through hole at the top of the second fixing plate 3, the bottom of the connecting post 5 contacts the top of the second fixing plate 3. At this time, the short rod 43 contacts the top of the sleeve 4 located below, which can press down the sleeve 4 located below, increasing the stability of the sleeve 4. The operator can move the sleeve 4 through the connecting ring 44 to easily put the sleeve 4 on the upright 1 or remove it from the upright 1.

[0017] like Figure 1 and Figure 2 As shown, each of the two sides of the upright 1 is provided with a set of fixing plates 2 and 3; a fixing block 21 is fixed to the top of the fixing plate 2, and a marking block 22 is fixed to the top of the fixing block 21. The front of the upright 1 is provided with a set of fixing plates 2 and 3, and the back of the upright 1 is also provided with a set of fixing plates 2 and 3 (totaling the number of fixing plates 2 and 3). Figure 1 (as shown in the diagram) This allows staff to fix several sleeves 4 onto the upright 1 in sequence. After the sleeve 4 is placed on the upright 1, when the corresponding marking block 22 of the sleeve 4 protrudes from the top of the sleeve 4, it indicates that the connecting post 5 inside the sleeve 4 is located between the first fixing plate 2 and the second fixing plate 3. At this time, the sleeve 4 can be rotated, which makes it easy for staff to rotate the sleeve 4 so that the connecting post 5 is located between the first fixing plate 2 and the second fixing plate 3.

[0018] like Figure 1 and Figure 2 As shown, the topmost fixing plate 2, fixing block 21, and marking block 22 on the upright 1 are all provided with corresponding screw holes. The upright 1 is provided with a screw 6 that is threadedly connected to the marking block 22. After several sleeves 4 are respectively fitted onto the upright 1, the operator can rotate the screw 6 so that the screw 6 enters into the topmost sleeve 4 on the upright 1. The bottom of the screw 6 can abut against the top of the connecting post 5 inside the sleeve 4, further completing the fixation of the sleeve 4. The remaining sleeves 4 will then be firmly fixed to the upright 1.

[0019] like Figure 3 As shown, the top of the connecting ring 44 is provided with an identification groove 45. The identification groove 45 corresponds to the connecting post 5, so that the operator can better determine the position of the connecting post 5 and thus rotate the sleeve 4.

[0020] like Figure 1 As shown, the top of the upright 1 has a recessed hole, into which a curved connecting rod 8 is inserted. A threaded bolt 9 passes through the upright 1, and the connecting rod 8 has a threaded hole that matches the bolt 9. The connecting rod 8 can be fixed to the top of the upright 1 using the bolt 9, and then the upright 1 can be suspended in a designated position using the connecting rod 8. The connecting rod 8 and the support frame 7 can be selected for use depending on the actual situation.

[0021] In use, the aluminum tube can be fitted onto two opposing suspension rods 42 (which can be made of titanium alloy), and then the sleeve 4 can be fitted onto the upright 1, so that the connecting post 5 is located on one side between the first fixing plate 2 and the second fixing plate 3. Then, rotate the sleeve 4 so that the connecting post 5 is located between the first fixing plate 2 and the second fixing plate 3, and then move the sleeve 4 downward so that the insertion rod 51 is inserted into the through hole at the top of the second fixing plate 3, thus completing the fixing of the sleeve 4. After fixing the other sleeves 4 in the same way, the upright 1 can be placed in the designated position by the support frame 7 to start the anodizing treatment of the aluminum tube. After the aluminum tube is anodized, simply move the sleeve 4 upward and then rotate the sleeve 4 to remove the connecting post 5 from between the first fixing plate 2 and the second fixing plate 3, and the sleeve 4 can be removed from the upright 1.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
