Description

Technical Field

[0001] This utility model belongs to the field of zinc alloy processing technology, and specifically relates to a zinc alloy processing and grinding device. Background Technology

[0002] Zinc alloys are alloys composed of zinc as the base metal and other elements added. Common alloying elements include aluminum, magnesium, and copper. Zinc alloys have a low melting point, good fluidity, and are easy to plastically process; common processing methods include die casting and machining. After processing, zinc alloys will have burrs on the surface, requiring grinding and polishing. This process not only smooths the surface but also removes areas of poor surface quality, improving the surface's mechanical properties.

[0003] Chinese patent CN213673284U discloses a zinc alloy processing and polishing device. This invention achieves workpiece lifting and lowering by setting an adjustment component, allowing the workpiece to switch between multiple workstations. Multiple surfaces of the workpiece can be polished with a single clamping, improving polishing efficiency. The polishing component allows the polishing disc to move horizontally, ensuring that every surface of the workpiece is thoroughly polished. A dust cover prevents polishing splatter from flying out and causing injury or contaminating the machine, facilitating cleaning.

[0004] While the aforementioned equipment can polish every side of the workpiece for a more comprehensive finish, it cannot polish the areas where the four corner chucks are fixed, thus limiting its effectiveness. Utility Model Content

[0005] The purpose of this invention is to provide a zinc alloy processing and grinding device to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A zinc alloy processing and grinding device includes a grinding and polishing mechanism. The grinding and polishing mechanism is externally equipped with a clamping mechanism and a guide rail mechanism. The grinding and polishing mechanism includes two symmetrical mounting frames and two symmetrical lifting blocks. A grinding and polishing disc is provided on one side of each lifting block that is close to the other. The grinding and polishing mechanism is used to grind and polish the upper and lower ends of the workpiece. The clamping mechanism includes a sliding plate, a second sliding plate, a first clamping frame, and a second clamping frame. The clamping mechanism is used to clamp the workpiece. The guide rail mechanism includes a receiving platform, a turning platform, and a turning disk. An installation cavity is formed above the turning platform. The turning disk is rotatably connected inside the installation cavity. The turning disk is used to temporarily support the workpiece and is used to rotate 90 degrees.

[0008] Preferably, a guide rail is fixedly connected between the receiving platform and the transforming platform, the first slide plate and the second slide plate are slidably connected inside the guide rail, and the two ends of the first clamping frame and the second clamping frame are fixedly connected to the first slide plate and the second slide plate.

[0009] Preferably, two symmetrical clamping plates are slidably connected to one side of the clamping frame, and a double-threaded rod is rotatably connected inside the clamping frame, with both ends of the double-threaded rod threadedly connected to one end of the clamping plate.

[0010] Preferably, two symmetrical clamping plates are slidably connected to one side of the clamping frame two, and a double threaded rod two is rotatably connected inside the clamping frame two. The two ends of the double threaded rod two are threadedly connected to one end of the clamping plate two. Two servo motors are installed on one side of the sliding plate two, and the output ends of the two servo motors are respectively connected to the double threaded rod one and the double threaded rod two.

[0011] Preferably, a stepper motor is installed inside the mounting cavity, and the output end of the stepper motor is connected to the bottom of the converter disk.

[0012] Preferably, the lifting block is slidably connected between two mounting brackets, and hydraulic cylinders are installed at the top and bottom of the mounting brackets. The output ends of the hydraulic cylinders are connected to both sides of the lifting block. A drive motor is installed on the side of the lifting block away from the grinding and polishing disc, and the output end of the drive motor is connected to the grinding and polishing disc.

[0013] Preferably, the mounting bracket has a through groove on its inner side, and two symmetrically distributed side plates are fixedly connected to both sides of the mounting bracket. A chip baffle is fixedly connected to the side of the side plates that are close to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] I. This utility model, through the coordinated operation of a grinding and polishing mechanism, a clamping mechanism, and a guide rail mechanism, allows the clamping mechanism to move the workpiece above the turntable and release it after the upper and lower surfaces and some sides of the workpiece have been ground and polished. Then, by rotating the turntable ninety degrees, the clamping mechanism clamps the workpiece again and transports it to the inside of the grinding and polishing mechanism for further grinding. This ensures that the sides of the workpiece are polished during the grinding and polishing process, resulting in a more uniform finish.

[0016] Second, through the cooperation of the grinding and polishing mechanism, the clamping mechanism and the guide rail mechanism, this utility model allows the grinding and polishing mechanism to grind and polish the upper and lower ends and some sides of the workpiece after the workpiece is placed on the receiving platform and clamped and positioned by the clamping mechanism, so that the workpiece does not need to be flipped separately, thereby reducing the cost of use.

[0026] 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.

[0027] Reference Figures 1-5 As shown, this utility model provides a zinc alloy processing and grinding device, including a grinding and polishing mechanism 1, and a clamping mechanism 2 and a guide rail mechanism 3 are provided on the outside of the grinding and polishing mechanism 1.

[0028] The grinding and polishing mechanism 1 includes two left-right symmetrical mounting brackets 11 and two up-down symmetrical lifting blocks 13. A grinding and polishing disc 15 is provided on the side of the lifting blocks 13 that are close to each other. The grinding and polishing mechanism 1 is used to grind and polish the upper and lower ends of the workpiece.

[0029] The clamping mechanism 2 includes a sliding plate 21, a sliding plate 22, a clamping frame 23, and a clamping frame 24. The clamping mechanism 2 is used to clamp the workpiece.

[0030] The guide rail mechanism 3 includes a receiving platform 31, a transformation platform 32, and a transformation disk 36. An installation cavity 34 is provided above the transformation platform 32. The transformation disk 36 is rotatably connected inside the installation cavity 34. The transformation disk 36 is used to temporarily support the workpiece and is used to rotate 90 degrees.

[0031] In a further embodiment, a guide rail 33 is fixedly connected between the receiving platform 31 and the transforming platform 32, and the first slide plate 21 and the second slide plate 22 are slidably connected inside the guide rail 33. The two ends of the clamping frame 23 and the clamping frame 24 are fixedly connected to the first slide plate 21 and the second slide plate 22.

[0032] In this embodiment, the guide rail 33 fits the first slide plate 21 and the second slide plate 22, and a motor is installed on one side of the mounting cavity 34, which allows the first slide plate 21 and the second slide plate 22 to slide within the guide rail 33 via bolts.

[0033] In a further embodiment, two symmetrical clamping plates 27 are slidably connected to one side of the clamping frame 23, and a double threaded rod 26 is rotatably connected inside the clamping frame 23. The two ends of the double threaded rod 26 pass through one end of the threaded connection clamping plate 27.

[0034] In this embodiment, sliding grooves are provided on the inner side of clamping frame 23 and clamping frame 24, so that a portion of clamping plate 27 and a portion of clamping plate 29 are slidably connected in the sliding grooves.

[0035] In a further embodiment, two symmetrical clamping plates 29 are slidably connected to one side of the clamping frame 24, and a double threaded rod 28 is rotatably connected inside the clamping frame 24. The two ends of the double threaded rod 28 pass through and are threaded to one end of the clamping plate 29. Two servo motors 25 are installed on one side of the sliding plate 22, and the output ends of the two servo motors 25 are respectively connected to the double threaded rod 26 and the double threaded rod 28.

[0036] In this embodiment, the double threaded rod 26 and the clamping plate 29 are driven by their respective servo motors 25. The operation of the double threaded rod 26 will cause the two clamping plates 27 to move closer together, while the rotation of the double threaded rod 28 will cause the two clamping plates 29 to move closer together, thereby clamping the workpiece. Since the two servo motors 25 operate at different times during clamping, it is possible to clamp irregularly shaped workpieces.

[0037] In a further embodiment, a stepper motor 35 is installed inside the mounting cavity 34, and the output end of the stepper motor 35 is connected to the bottom of the turntable 36.

[0038] In this embodiment, the stepper motor 35 can drive the turntable 36 to rotate 90 degrees after it is activated.

[0039] In a further embodiment, the lifting block 13 is slidably connected between two mounting brackets 11. Hydraulic cylinders 12 are installed on the upper and lower sides of the mounting brackets 11. The output ends of the hydraulic cylinders 12 are connected to both sides of the lifting block 13. A drive motor 14 is installed on the side of the lifting block 13 away from the polishing disc 15. The output end of the drive motor 14 is connected to the polishing disc 15.

[0040] In this embodiment, the mounting bracket 11 has sliding grooves on both sides near the lifting block 13, so that the lifting block 13 can be slidably connected, and the output end of the hydraulic cylinder 12 passes through the sliding groove and is connected to both ends of the lifting block 13.

[0041] In a further embodiment, a through groove 16 is provided on the inner side of the mounting bracket 11, and two symmetrically distributed side plates 17 are fixedly connected to both sides of the mounting bracket 11. A chip baffle 18 is fixedly connected to the side of the side plates 17 that are close to each other.

[0042] In this embodiment, the chip baffle 18 is used to block the waste chips during grinding, and the through groove 16 is used to remove the waste chips.

[0043] The working principle of this utility model is as follows:

[0044] When the clamping mechanism 2 is above the receiving platform 31, the workpiece is placed above the receiving platform 31 and the two servo motors 25 are started to rotate the double threaded rod 26 and the double threaded rod 28, so that the clamping plate 27 and the clamping plate 29 clamp the workpiece. Then, the clamping mechanism 2 is moved through the guide rail 33 to the inside of the grinding and polishing mechanism 1. Then, the drive motors 14 at the upper and lower ends of the mounting frame 11 are operated by the external control equipment, and the upper hydraulic cylinder 12 is operated to grind and polish the upper surface and side of the workpiece. Then, the hydraulic cylinder 12 above the mounting frame 11 is retracted, so that the lifting block 13 moves the drive motor 14 and the grinding and polishing disc 15 upward, so that the upper grinding and polishing disc 15 moves away from the workpiece. Then, the lower hydraulic cylinder 12 is operated to grind and polish the lower surface and side of the workpiece, so that both the upper and lower surfaces of the workpiece can be ground and polished.

[0045] After the upper and lower surfaces and some sides of the workpiece are polished, the clamping mechanism 2 reaches the top of the turntable 32 as the guide rail 33 continues to push. Then, the reverse drive servo motor 25 releases the workpiece, allowing it to be carried by the turntable 36. The stepper motor 35 is then operated to rotate the turntable 36 with the workpiece by 90 degrees. The servo motor 25 is then operated again to clamp the workpiece again, and the clamping mechanism 2 moves the workpiece back to the inside of the polishing mechanism 1 for further polishing. This process polishes the sides of the workpiece more evenly.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
