Description

Technical Field

[0001] This utility model relates to the field of titanium profile processing technology, specifically to a workpiece hanger for micro-arc oxidation of titanium profiles. Background Technology

[0002] Micro-arc oxidation of titanium profiles is a technology for preparing an oxide layer on the surface of titanium alloys. It utilizes the high temperature and high pressure environment generated by micro-arc discharge in an electrolyte to form a protective layer mainly composed of base metal oxides on the metal surface. This technology can significantly improve the wear resistance, hardness, and corrosion resistance of titanium alloys, and also has good electrical insulation properties. The workpiece hanger for titanium alloy micro-arc oxidation is a device used to suspend the workpiece to be processed within the micro-arc oxidation equipment.

[0003] The utility model with authorization publication number CN215481352U provides a workpiece hanger for micro-arc oxidation of titanium alloys. Multiple hanging devices are arranged in an array on both sides of the hanging rod. Each hanging device can suspend a workpiece, which effectively improves the space utilization of the hanger and enables the micro-arc oxidation equipment to perform coating processing on multiple workpieces at one time.

[0004] However, in the aforementioned patent, the distance between two adjacent mounting devices is not adjustable. If the length of the workpiece to be processed is greater than the distance between the two adjacent mounting devices, the mounting device located below will interfere with the workpiece suspended above it. At the same time, the distance between the mounting device and the hanging rod is also not adjustable. If the workpiece to be processed is wide, the hanging rod will interfere with the workpiece suspended on the mounting device, and the workpiece will not be able to be suspended vertically on the mounting device, reducing the stability of the workpiece suspended on the fixture. In view of this, we propose a workpiece fixture for micro-arc oxidation of titanium profiles. Utility Model Content

[0005] The purpose of this invention is to provide a workpiece hanger for micro-arc oxidation of titanium profiles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, one of the objectives of this utility model is to provide a workpiece hanger for micro-arc oxidation of titanium profiles, including a vertical rod. A rack is fixedly connected to one side of the vertical rod. Several carrier plates are slidably sleeved on the vertical rod and the rack, and the carrier plates and the vertical rod are coaxially arranged. A lifting mechanism is provided on the upper side of the carrier plate, which is used to adjust the position of the carrier plate on the vertical rod. Several rotating rods are rotatably connected in a circular array on the lower side of the carrier plate. A hook groove is opened on the upper side of the rotating rod, and the hook groove is located at the end of the rotating rod away from the axis of the vertical rod and on the outside of the carrier plate. A synchronization mechanism is provided between the several rotating rods. The synchronization mechanism is located on the lower side of the carrier plate. When any one rotating rod rotates, the synchronization mechanism drives the other rotating rods to rotate synchronously.

[0007] As a further improvement to this technical solution, the lifting mechanism includes a rotating shaft rotatably mounted on the upper side of the carrier plate. A lifting gear and a worm gear are coaxially and fixedly connected on the rotating shaft. The lifting gear meshes with a rack. A worm is rotatably mounted on the upper side of the carrier plate. The worm meshes with a worm wheel, and a crank handle is fixedly connected to one end of the worm.

[0008] As a further improvement to this technical solution, the synchronization mechanism includes a synchronization gear coaxially disposed on the lower side of the carrier disk. The position where the rotating rod and the carrier disk are rotatably connected is located at one end of the rotating rod near the axis of the carrier disk, and a half gear is fixedly connected at the position where the rotating rod and the carrier disk are connected. Several of the half gears mesh with the synchronization gear.

[0009] As a further improvement to this technical solution, the synchronization mechanism also includes a positioning ring coaxially disposed inside the synchronization gear. The positioning ring is fixedly disposed on the lower surface of the carrier plate. The side profile of the positioning ring is an L-shaped structure. The inner circumferential wall and the lower side surface of the synchronization gear are in sliding contact with the positioning ring. An embedded groove is provided on the positioning ring, and a rubber ring is fixedly disposed inside the embedded groove. The rubber ring is in sliding contact with the lower side surface of the synchronization gear.

[0010] As a further improvement to this technical solution, an upper blocking block is fixedly connected to the upper end of the upright, and a hook is rotatably provided at the center of the upper side of the upper blocking block. A lower blocking block is coaxially fixedly connected to the side wall of the upright, and the lower blocking block and the upper blocking block are respectively in contact with the two ends of the rack.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This workpiece hanger for micro-arc oxidation of titanium profiles, by rotating a worm gear, drives a worm wheel and a lifting gear to rotate, which allows the carrier plate to move along the axis of the upright. This adjusts the distance between two adjacent carrier plates, making it convenient for workers to suspend workpieces of different lengths under the two adjacent carrier plates. At the same time, by rotating any one of the rotating rods, the worker can cause the synchronization mechanism to drive the other rotating rods under the same carrier plate to rotate synchronously. This adjusts the distance between the hook grooves on several rotating rods under the same carrier plate and the axis of the upright, making it convenient for workers to suspend workpieces of different widths on the rotating rods. While ensuring the space utilization of the hanger, it also improves the stability of workpieces of different sizes when suspended on the hanger. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-6As shown, one of the objectives of this embodiment is to provide a workpiece hanger for micro-arc oxidation of titanium profiles, including a pole 1, a rack 2 fixedly connected to one side of the pole 1, an upper block 12 fixedly connected to the upper end of the pole 1, and a hook 11 rotatably disposed at the center of the upper side of the upper block 12. By hooking the hook 11 to a perforated plate disposed on the top surface of the micro-arc oxidation equipment, the hanger can be suspended inside the micro-arc oxidation equipment. Several carrier plates 3 are slidably sleeved on the pole 1 and the rack 2, and the carrier plates 3 and the pole 1 are coaxially arranged. There is a gap between two adjacent carrier plates 3 sufficient to accommodate the workpiece. A lower block 13 is coaxially fixedly connected to the side wall of the pole 1. The lower block 13 and the upper block 12 are respectively connected to both ends of the rack 2. The lower block 13 and upper block 12 restrict the movement path of the carrier plate 3 to prevent the carrier plate 3 from losing contact with the rack 2 and the risk of the carrier plate 3 falling off. Several rotating rods 5 are rotatably connected in a ring array on the lower side of the carrier plate 3. The upper side of the rotating rod 5 is provided with a hook groove 51. The hook groove 51 is located at the end of the rotating rod 5 away from the axis of the upright rod 1 and is located on the outside of the carrier plate 3. The workpiece to be processed is provided with a through hole or a hanging groove. The worker hooks the through hole or hanging groove on the workpiece with the hook groove 51 to suspend the workpiece on the rotating rod 5. In this way, several workpieces are suspended on the lower side of several carrier plates 3. Then, the hanger is suspended inside the micro-arc oxidation equipment, and several workpieces can be coated at the same time using the micro-arc oxidation equipment.

[0028] During the micro-arc oxidation process, workpieces of different sizes may exist. If the length of a workpiece is greater than the distance between two adjacent carrier plates 3, the two workpieces suspended below the adjacent carrier plates 3 are prone to collision and interference, causing the workpiece to easily fall off the rotating rod 5 and be damaged, affecting the production and processing of the workpiece. To solve this problem, a lifting mechanism 4 is provided on the upper side of the carrier plate 3. The lifting mechanism 4 is used to adjust the position of the carrier plate 3 on the upright rod 1. The structure of the lifting mechanism 4 is detailed below, referring to... Figure 3The lifting mechanism 4 includes a rotating shaft 41 rotatably mounted on the upper side of the carrier plate 3. A lifting gear 42 and a worm gear 43 are coaxially fixedly connected to the rotating shaft 41. The lifting gear 42 meshes with a rack 2. A worm 44 is rotatably mounted on the upper side of the carrier plate 3. The worm 44 meshes with the worm gear 43, and a handle 45 is fixedly connected to one end of the worm 44. When the worker holds the handle 45 and rotates the worm 44, the meshing transmission between the worm 44 and the worm gear 43 causes the worm gear 43 to drive the rotating shaft 41 to rotate. The rotating shaft 41 then drives the lifting gear 42 to rotate. The meshing transmission with the rack 2 causes the lifting gear 42 to drive the carrier plate 3 to move vertically along the axis of the upright 1. After the worker moves the carrier plate 3 to the predetermined position, he stops rotating the worm gear 44. Through the self-locking property of the meshing transmission between the worm gear 44 and the worm wheel 43, the rotation of the rotating shaft 41 and the lifting gear 42 is restricted, so that the carrier plate 3 will not fall off under the action of gravity. In this way, the distance between two adjacent carrier plates 3 can be adjusted, so that the worker can suspend workpieces of different lengths on the rotating rod 5. When using this hanger to suspend workpieces for coating processing, the possibility of the workpiece falling off the hanger is reduced.

[0029] Meanwhile, the widths of workpieces of different sizes also vary. When workers suspend wider workpieces on the rotating rod 5, the workpieces are prone to collision and interference with the side wall of the upright rod 1. To solve this problem, workers rotate the rotating rod 5 to move the hook groove 51 away from the axis of the upright rod 1. This prevents the workpiece from contacting the side wall of the upright rod 1 when suspending it on the rotating rod 5, allowing the workpiece to be suspended perpendicular to the ground. However, during the suspension process, workers need to rotate several rotating rods 5 one by one on the lower side of the same carrier plate 3, reducing the efficiency of suspending workpieces on the hanger. To solve this problem, a synchronization mechanism 6 is set between several rotating rods 5. The synchronization mechanism 6 is located on the lower side of the carrier plate 3. When any rotating rod 5 rotates, the synchronization mechanism 6 drives the other rotating rods 5 to rotate synchronously. The structure of the synchronization mechanism 6 is detailed below, refer to Figure 4 and Figure 5The synchronization mechanism 6 includes a synchronization gear 61 coaxially mounted on the lower side of the carrier plate 3. The rotating rod 5 and the carrier plate 3 are rotatably connected at one end of the rotating rod 5 near the axis of the carrier plate 3. A half gear 52 is fixedly connected at the connection point between the rotating rod 5 and the carrier plate 3. Several half gears 52 mesh with the synchronization gear 61. A positioning ring 62 is coaxially mounted inside the synchronization gear 61 and is fixedly mounted on the lower surface of the carrier plate 3. The side profile of the positioning ring 62 is L-shaped. The inner circumferential wall and the lower side of the synchronization gear 61 are in sliding contact with the positioning ring 62. The L-shaped positioning ring 62, in conjunction with the carrier plate 3, restricts the synchronization gear 61. Vertical and horizontal movement allows the synchronizing gear 61 to rotate only around the axis of the upright 1. When the worker rotates any one of the rotating rods 5, the half gears 52 on the rotating rod 5 rotate synchronously. The rotating half gears 52 mesh with the synchronizing gear 61, driving the synchronizing gear 61 to rotate. The synchronizing gear 61 then drives the other meshing half gears 52 to rotate synchronously. The rotating half gears 52 drive the corresponding rotating rods 5 to rotate. In this way, several rotating rods 5 on the underside of the same carrier plate 3 rotate synchronously, making it convenient for the worker to adjust the distance between the hook groove 51 and the axis of the upright 1 according to the width of the workpiece, so as to suspend workpieces of different widths.

[0030] And refer to Figure 6 An embedded groove is provided on the positioning ring 62, and a rubber ring 63 is fixedly installed inside the embedded groove. The rubber ring 63 slides in contact with the lower side of the synchronous gear 61. Due to the large coefficient of friction between the rubber ring 63 and the synchronous gear 61, the frictional resistance that the synchronous gear 61 needs to resist when rotating is increased, so that the worker needs to use more force when rotating the rotating rod 5. In this way, after the worker rotates the rotating rod 5 to the predetermined position, the position of the rotating rod 5 is prevented from changing easily, the stability of the workpiece after being suspended on the rotating rod 5 is increased, and the coating quality of the workpiece by the micro-arc oxidation equipment is guaranteed.
