Description

Technical Field

[0001] This utility model belongs to the field of magnetic grinding technology, specifically relating to a magnetic grinding device for alloy steel rods. Background Technology

[0002] Magnetic abrasive grinding equipment for alloy steel bars is a device used to treat the surface of alloy steel bars. Its main function is to remove burrs, scale, oil, and other impurities from the surface of the alloy steel bars, improving their surface smoothness and precision, and thus enhancing surface quality. Currently, the main consensus regarding the shortcomings of these grinding equipment is as follows: In traditional magnetic grinding of alloy steel bars, all surfaces of the steel bar need to be ground magnetically. However, since the steel bar is usually gripped and suspended by a clamping device, some parts of the steel bar are not ground. Grinding can only be carried out after the clamping position is changed, which increases the time required for grinding and reduces the efficiency of grinding the steel bar. Utility Model Content

[0003] The purpose of this utility model is to provide a magnetic grinding device for alloy steel bars, which aims to solve the problem that in the prior art, alloy steel bars are generally ground by clamping and suspending them with a clamping device, and grinding can only be carried out after the clamping position of the alloy steel bars is changed, which increases the time required for grinding alloy steel bars.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A magnetic grinding device for alloy steel bars includes a grinding tank. Rotating frames are rotatably connected to the inner walls of both sides of the grinding tank. Two connecting rods are fixedly installed between the two rotating frames. Two outer frames are slidably connected between the rotating frames. Cover plates are rotatably connected to the two outer frames. Multiple support slots are fixedly installed on one side of each cover plate. Adjusting screws are threaded to both ends of each outer frame, and the two ends of the adjusting screws rotate on the rotating frames. A partition disk is rotatably connected to the inner wall of the grinding tank, and a magnetic disk is fixedly installed on the inner wall of the partition disk.

[0005] In a preferred embodiment of this utility model, drive rods are rotatably connected to the inner walls of both ends of the rotating frame. A bevel gear is fixedly installed at one end of the drive rod and the top end of the adjusting screw, and a drive gear is fixedly installed at the other end of the drive rod.

[0006] As a preferred embodiment of this invention, an inner toothed ring and an outer toothed ring are fixedly installed on both sides of the inner wall of the grinding pool.

[0007] In a preferred embodiment of this invention, a main motor and an auxiliary motor are respectively installed on the outside of the grinding tank. The output end of the main motor is fixedly connected to one side of the partition disk, and one of the rotating frames is fixedly connected to the output end of the auxiliary motor.

[0008] As a preferred embodiment of this utility model, the inner sidewall of the outer frame is threadedly connected to a fixing rod, and the outer side of the fixing rod is threadedly connected to the outer side of the cover plate.

[0009] In a preferred embodiment of this invention, an outer frame is installed at the top of the grinding tank, a tank cover is slidably connected to the inner side wall of the outer frame, and a support frame is fixedly installed at the bottom of the grinding tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1) The outer frame and cover plate can be used to engage the alloy steel rod through the slot in the cover plate. When the alloy steel rod is engaged with the slot below, the slot below the alloy steel rod can be ground. After the grinding, the outer frame can be moved downwards, so that the slot above the alloy steel rod can gradually move towards the top of the alloy steel rod and fit together. This allows the alloy steel rod to rotate while rotating. When the alloy steel rod rotates to the point where the bottom end is facing upwards, the slot at the unground end of the alloy steel rod will disengage from the alloy steel rod. At this point, the magnetic force of the magnetic rod inside the grinding tank can continue to grind the alloy steel rod. Thus, the entire alloy steel rod can be ground without manual operation.

[0011] 2) By engaging the drive gears with the internal or external gear rings respectively, the outer frame can move downward or upward inside the rotating frame, thereby limiting and fixing the alloy steel rod at both ends or disengaging one end, so as to facilitate the continuous rotation of the alloy steel rod and make it easier to grind the ungrinded part of the alloy steel rod.

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-5 The present invention provides the following technical solution: a magnetic grinding device for alloy steel bars, comprising a grinding pool 1, rotating frames 2 rotatably connected to the inner walls of both sides of the grinding pool 1, two connecting rods 21 fixedly installed between the two rotating frames 2, two outer frames 3 slidably connected between the rotating frames 2, cover plates 4 rotatably connected to the two outer frames 3, multiple brackets 41 fixedly installed on one side of the cover plate 4, adjusting screws 5 threadedly connected to both ends of the outer frames 3, the two ends of the adjusting screws 5 rotating on the rotating frames 2, a partition disk 6 rotatably connected to the inner wall of the grinding pool 1, and a magnetic disk 61 fixedly installed on the inner wall of the partition disk 6.

[0016] In practical use, with one of the outer frames 3 and the cover plate 4 facing upwards, the cover plate 4 can be rotated on the outer frame 3 to open, allowing the alloy steel rod to be placed inside the corresponding slot 41 of the lower cover plate 4. Then, the cover plate 4 is rotated on the outer frame 3 to close. At this time, the spacer disk 6 drives the magnetic disk 61 to rotate, and the magnetic rods and magnetic needles inside the grinding pool 1, which are submerged in the alloy steel rod, can perform grinding on the areas except for the lower slot 41. After the grinding, the rotation of the rotating frame 2 inside the grinding pool 1 causes the adjusting screws 5 at both ends of the upper outer frame 3 to rotate, driving the outer frame 3 downwards, so that the slot 41 above the alloy steel rod can gradually move towards the top of the alloy steel rod. The end moves and fits together, so that the alloy steel rod can be rotated while rotating. When the alloy steel rod rotates to the lateral position, the two support grooves 41 fix the two ends of the alloy steel rod. When the rotating frame 2 continues to rotate, the adjusting screws 5 at both ends of the other outer frame 3 rotate in the opposite direction, so that the outer frame 3 slides inside the rotating frame 2 and gradually separates from the other end of the alloy steel rod. After the alloy steel rod rotates to the inverted position, the support groove 41 at the un-grinded end of the alloy steel rod separates from the alloy steel rod. At this time, the alloy steel rod can continue to be ground by the magnetic force of the magnetic rod inside the grinding pool 1. Thus, the entire alloy steel rod can be ground without manual operation.

[0017] Preferably, the inner walls of both ends of the rotating frame 2 are rotatably connected to a drive rod 51. One end of the drive rod 51 and the top end of the adjusting screw 5 are both fixedly installed with a bevel gear 52, and the other end of the drive rod 51 is fixedly installed with a drive gear 53.

[0018] In practical use, when the adjusting screw 5 needs to rotate, the driving gear 53 at the corresponding position can drive the driving rod 51 to rotate, so that the driving rod 51 can drive the adjusting screw 5 to rotate in the opposite or forward direction through the action of the bevel gear 52, thereby driving the outer frame 3 to slide on the rotating frame 2.

[0019] Preferably, an inner toothed ring 54 and an outer toothed ring 55 are fixedly installed on both sides of the inner wall of the grinding pool 1.

[0020] In practical use, when the drive gear 53 meshes with the outer gear ring 55, it can drive the outer frame 3 to move downward and gradually contact the top of the alloy steel rod, thereby limiting and fixing the alloy steel rod so that the alloy steel rod can continue to rotate. When the drive gear 53 meshes with the inner gear, it can cause the outer frame 3 at the current position to move upward, so that the outer frame 3 is separated from the other end of the alloy steel rod, so that the un-grinded part of the alloy steel rod can be ground.

[0021] Preferably, a main motor 7 and an auxiliary motor 8 are installed on the outside of the grinding tank 1. The output end of the main motor 7 is fixedly connected to one side of the partition disk 6, and one of the rotating frames 2 is fixedly connected to the output end of the auxiliary motor 8.

[0022] In practical use, the main motor 7 is used to drive the magnetic disk 61 to rotate, so that the magnetic rods and magnetic needles inside the grinding pool 1 can perform magnetic grinding on the alloy steel rod. The auxiliary motor 8 is used to drive the rotating frame 2 to rotate, so as to flip the alloy steel rod.

[0023] Preferably, the inner wall of the outer frame 3 is threaded with a fixing rod 31, and the outer side of the fixing rod 31 is threaded with the outer side of the cover plate 4.

[0024] In practical use, the outer frame 3 and the cover plate 4 can be connected or disconnected through the fixing rod 31, which makes it easier to put in and take out the alloy steel rod.

[0025] Preferably, an outer frame 9 is installed at the top of the grinding tank 1, a tank cover 91 is slidably connected to the inner side wall of the outer frame 9, and a support frame 10 is fixedly installed at the bottom of the grinding tank 1.

[0026] In practical use, the pool cover 91 is used to close the overall opening of the grinding pool 1, and the support frame 10 provides support for the entire device.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
