Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of polishing equipment, and in particular relates to an alloy bar processing and polishing equipment. Background Technology
[0002] Alloy bars are metallic materials with specific lengths and cross-sectional shapes. They are usually made with iron, nickel, cobalt, titanium, etc. as the base material and added with elements such as chromium, molybdenum, and aluminum. Some alloy bars are made by adding special components such as carbon, hydrogen, or non-metallic elements to enhance their properties. Alloy bars have higher hardness and strength than pure metals, and have better corrosion resistance and heat resistance than pure metals. Alloy bars are widely used in aerospace, energy, machinery, and medical device fields.
[0003] After alloy bars are smelted and cast, they still need to undergo surface polishing and other finishing processes. Traditional polishing equipment usually operates with a constant preset pressure. This constant pressure cannot adapt to the diameter changes of the alloy bars due to slight wear during polishing, which may result in uneven polishing effects. When the polishing precision needs to be adjusted, the machine needs to be stopped to replace polishing wheels of different specifications, reducing production continuity and work efficiency. At the same time, traditional polishing equipment often uses fixed clamps designed for specific diameters. To process alloy bars of different diameters, the corresponding clamps need to be changed. During the polishing process, as the surface material of the bar is continuously ground, its diameter gradually decreases. The fixed-size clamps cannot adaptively tighten, which may cause the bar to slip and affect the quality of the finished product. Utility Model Content

Detailed Implementation
[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-5This utility model provides a technical solution: an alloy bar processing and polishing equipment, including an operating table 1, an installation plate 2 connected to one side of the operating table 1, a polishing mechanism 4, the polishing mechanism 4 including a dust cover 410 disposed on one side of the installation plate 2, a drive gear 411 rotatably connected to the inner wall of the dust cover 410, a driven gear 412 rotatably connected to the inner wall of the dust cover 410, polishing wheels 413 connected to both sides of the driven gear 412, the polishing wheels 413 being configured to follow the driven gear 412 in rotation to polish the surface of the alloy bar, and a clamping mechanism 5, the clamping mechanism 5 including a housing 501 connected to the top of the operating table 1, a moving block 502 slidably connected inside the housing 501, a contact wheel 507 rotatably connected to the top of the moving block 502, the contact wheel 507 being configured to have its outer wall in contact with the outer surface of the alloy bar and push the moving block 502 to move.
[0019] A mounting bracket 401 is slidably connected to one side of the outer wall of the mounting plate 2. A telescopic rod 403 is provided through one side of the outer wall of the mounting bracket 401. An electric push rod 415 is installed on the inner wall of the mounting bracket 401. The push rod of the electric push rod 415 is connected to one end of the telescopic rod 403.
[0020] Both ends of one side of the mounting bracket 401 are connected to limit blocks 402. Both sides of one end of the telescopic rod 403 are rotatably connected to rotating rods 404. One end of the two rotating rods 404 is hinged, and the other end of the two rotating rods 404 passes through the limit blocks 402 at the corresponding positions.
[0021] A connecting frame 405 is rotatably connected to the middle of the rotating rod 404. A connecting rod 409 is rotatably connected to the inner wall of the connecting frame 405. One end of the connecting rod 409 is connected to the outer wall of one side of the dust cover 410.
[0022] One end of the connecting rod 409 and one end of the connecting frame 405 are rotatably connected to a rotating block 406. A first sleeve rod 407 is connected between the two rotating blocks 406. A first spring 408 is sleeved on the outside of the first sleeve rod 407. The two ends of the first spring 408 are respectively connected to the outer wall of the rotating block 406 at the corresponding position.
[0023] A motor 414 is installed on one side of the dust cover 410. The output end of the motor 414 is connected to one side of the drive gear 411. A slider 416 is connected to one side of the outer wall of the mounting bracket 401. A groove 3 is opened on one side of the outer wall of the mounting plate 2. The outer wall of the slider 416 is slidably connected to the inner wall of the groove 3.
[0024] Specifically, the push rod of the electric push rod 415 extends to push the telescopic rod 403, which extends forward. The two rotating rods 404 rotate around the hinge point, causing their other ends to be pulled out of the limiting block 402. As the telescopic rod 403 moves, the included angle between the two rotating rods 404 decreases, causing the two connecting frames 405 to move closer together. The connecting frames 405 drive the connecting rod 409 to move, causing the two connecting rods 409 to move closer together as well. The connecting rods 409 drive the dust cover 410 to move, causing the two dust covers 410 to move closer together as well. The polishing wheel 413 moves with the dust cover 410. After the polishing wheel 413 comes into contact with the outer surface of the alloy bar, it applies pressure to the outer surface of the alloy bar. The outer surface of the alloy bar faces the polishing wheel 413. A reaction force is applied radially to the dust cover 410, causing the end of the connecting rod 409 connected to the dust cover 410 away from the dust cover 410 to rotate counterclockwise. The first spring 408 is stretched, and the first spring 408 pulls the end of the connecting rod 409 away from the dust cover 410 through its own elasticity to prevent the dust cover 410 from lifting, so that the polishing wheel 413 is always in close contact with the outer surface of the alloy bar. The motor 414 drives the drive gear 411 to rotate through the output end. The drive gear 411 meshes with the teeth on the outer wall of the driven gear 412 through the teeth on the outer wall. The drive gear 411 drives the driven gear 412 to rotate, and the polishing wheel 413 follows the driven gear 412 to rotate, polishing the outer surface of the alloy bar.
[0025] It should be noted that the electric push rod 415 mentioned above is a new type of linear actuator composed of a motor 414, a push rod, and a control device. It is an electric drive device that converts the rotary motion of the electric motor into the linear reciprocating motion of the push rod. This part is well-known technology in the field and will not be described in detail here.
[0026] It should be noted that the selection of electric actuator 415 and motor 414, as well as the selection of control unit in the above description, are all selected as needed. This part is well-known technology in the field and will not be elaborated here.
[0027] Limiting rods 503 are provided on both sides of the movable block 502. The outer wall of one side of the limiting rod 503 is slidably connected to the outer wall of one side of the movable block 502. A linkage rod 506 is rotatably connected to the inner wall of the outer shell 501. Both ends of the linkage rod 506 are rotatably connected to the contact wheel 507.
[0028] The bottom of the movable block 502 is connected to a second sleeve rod 504, and a second spring 505 is sleeved on the outside of the second sleeve rod 504. The two ends of the second spring 505 are respectively connected to the corresponding positions of the bottom outer wall of the movable block 502 and the bottom inner wall of the outer shell 501.
[0029] Specifically, the cross-sectional shape of the middle part of the movable block 502 is triangular. When the alloy bar is placed between the two linkage rods 506, the contact wheel 507 at the top of the movable block 502 contacts the outer surface of the alloy bar and pushes the movable block 502 downward. The contact wheel 507 at the bottom of the linkage rod 506 fits against the triangular inclined surface of the movable block 502. When the movable block 502 moves downward, the second spring 505 is compressed. The second spring 505 pushes the movable block 502 upward through its elastic force, supporting the movable block 502. While keeping the position of 502 relatively fixed, the contact wheel 507 at the top of the moving block 502 makes closer contact with the outer surface of the alloy bar. The contact wheel 507 at the bottom of the linkage rod 506 slides downward along the triangular inclined plane of the moving block 502, so that the other ends of the two linkage rods are close to each other and the contact wheel 507 at the top of the linkage rods contacts the outer surface of the alloy bar. The position between the contact wheel 507 at the top of the two linkage rods 506 and the contact wheel 507 at the top of the moving block 502 forms a triangle, so that the alloy bar is stably clamped.
[0030] Working principle: In use, the operator places both ends of the alloy bar on the clamping mechanism 5, then presses the alloy bar down to clamp both ends of the alloy bar with the clamping mechanism 5. Then, the operator moves the polishing mechanism 4 to the designated position along the slide groove 3. Then, the operator starts the electric push rod 415 to make the polishing wheel 413 of the polishing mechanism 4 fit tightly with the alloy bar. Then, the operator starts the motor 414 to polish the area to be polished. After polishing is completed, the operator starts the electric push rod 415 in the opposite direction to separate the polishing wheel 413 of the polishing mechanism 4 from the alloy bar. Then, the operator moves the polishing mechanism 4 to other positions along the slide groove 3 and repeats the above operation.
