Description

Technical Field

[0001] This utility model belongs to the field of metal deburring technology, specifically relating to a high-efficiency grinding and deburring device for sintered powder metallurgy metal parts. Background Technology

[0002] The high-efficiency grinding and deburring device for sintered powder metallurgy parts is a specialized piece of equipment designed specifically for the characteristics of powder metallurgy parts, namely "low strength, porosity, and susceptibility to burrs." Its core purpose is to efficiently, accurately, and protectively remove burrs in mass production, solving the problems of low efficiency and poor consistency associated with manual grinding while avoiding damage to workpieces caused by ordinary grinding equipment. Ultimately, this ensures the assembly performance, safety of use, and stability of subsequent processing of the parts. Currently, grinding and deburring devices mainly suffer from the following commonly accepted shortcomings:

[0003] In traditional deburring operations on metal parts, the parts need to be manually retrieved after being placed in the ultrasonic deburring device, and their positions are relatively fixed, which can easily lead to uneven deburring. Furthermore, traditional deburring devices cannot easily retrieve and move the metal parts, reducing the overall efficiency and ease of operation of the device for deburring metal parts. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency grinding and deburring device for sintered powder metallurgy metal parts, which aims to solve the problem that the existing technology cannot easily retrieve and move the metal parts, thus reducing the efficiency and ease of operation of the overall device for grinding and deburring the metal parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency grinding and deburring device for sintered powder metallurgy parts includes a grinding box. A main shaft is rotatably connected to the inner wall of the grinding box. Four partition plates are fixedly installed on the outer side of the main shaft. A discharge plate is slidably connected to the top of the four partition plates. A drive screw is rotatably connected to the inner wall of the top of the partition plates. The outer side of the drive screw is threadedly connected to the inside of the discharge plate. One end of the drive screw is rotatably connected to the inside of the main shaft. An ultrasonic generator is fixedly installed on the inner wall of the bottom end of the grinding box.

[0007] As a preferred embodiment of this utility model, an inner plate is also fixedly installed on the outer side of one end of the main rotating shaft, and the outer side of the inner plate is rotatably connected to the inner side wall of the grinding box.

[0008] In a preferred embodiment of this utility model, the main shaft is internally rotatably connected to four main rods, and a bevel gear is fixedly installed at one end of each of the four main rods and one end of the drive screw.

[0009] In a preferred embodiment of this utility model, four auxiliary rods are rotatably connected to the inner sidewall of the inner plate. A spur gear is fixedly installed at one end of each of the four auxiliary rods, and a pulley is fixedly installed at the other end of both the auxiliary rods and the main rod. A transmission belt is sleeved on the outer side of each pulley.

[0010] In a preferred embodiment of this invention, an inner ring is fixedly installed on one side of the inner wall of the grinding box, and an internal gear ring and an external gear ring are fixedly installed on one side of the inner ring, both of which mesh with spur gears.

[0011] In a preferred embodiment of this invention, a motor is fixedly mounted on the outside of the grinding box, and the output end of the motor is fixedly connected to one end of the main rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By continuously rotating the partition plate inside the grinding box, metal parts can be added to the grinding box in sections, and after grinding and deburring, they are easier to take out from the other end of the grinding box. The partition plate can increase the uniformity of the size of the metal parts as they move inside the grinding box. In addition, the drive screw pushes the discharge plate, so that the metal parts can be moved outward by the movement of the discharge plate, making it easier to pick up the metal parts.

[0014] 2) By rotating the inner plate inside the grinding box, the upper auxiliary rod can interact with the inner or outer gear ring at a specific position. When the partition plate rotates to the upward horizontal direction, the upper discharge plate can push the metal parts outward. When it rotates to the vertical direction, the discharge plate slides back into the partition plate, improving the convenience of loading and unloading metal parts in the overall equipment.

[0022] 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.

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a high-efficiency grinding and deburring device for sintered powder metallurgy metal parts, comprising a grinding box 1, a main rotating shaft 2 rotatably connected to the inner wall of the grinding box 1, four partition plates 3 fixedly installed on the outer side of the main rotating shaft 2, a discharge plate 4 slidably connected to the top of the four partition plates 3, a drive screw 31 rotatably connected to the top inner wall of the partition plates 3, the outer side of the drive screw 31 being threadedly connected to the inside of the discharge plate 4, one end of the drive screw 31 being rotatably connected to the inside of the main rotating shaft 2, and an ultrasonic generator 5 fixedly installed on the bottom inner wall of the grinding box 1.

[0024] In practical use, when it is necessary to grind and deburr metal parts, the metal parts can be placed on the partition plate 3. The main shaft 2 drives the partition plate 3 to rotate, allowing the metal parts to gradually enter the grinding box 1 and come into contact with the cutting fluid. The ultrasonic generator 5 acts on the abrasive to grind and deburr the metal parts. At the same time, the main shaft 2 drives the partition plate 3 to rotate continuously, allowing the metal parts to change positions inside the grinding box 1, increasing the uniformity and effect of grinding and deburring. After the metal parts are ground and deburred, the partition plate 3 can be continuously rotated to retrieve the metal parts onto the discharge plate 4 and rotate it to a horizontal position. At this time, the continuous rotation of the main shaft 2 causes the drive screw 31 to rotate on the partition plate 3, thereby driving the discharge plate 4 to slide outward on the partition plate 3, sending the metal parts on the discharge plate 4 outward, making it easier to pick up the metal parts.

[0025] Preferably, an inner plate 21 is fixedly installed on the outer side of one end of the main rotating shaft 2, and the outer side of the inner plate 21 is rotatably connected to the inner side wall of the grinding box 1.

[0026] In practical use, the main shaft 2 rotates while simultaneously driving the inner plate 21 to rotate inside the grinding box 1, thereby enabling the movement of the discharge plate 4 at a specific position on the partition plate 3.

[0027] Preferably, the main shaft 2 is internally connected to four main rods 22, and one end of each of the four main rods 22 and one end of the drive screw 31 are fixedly mounted with bevel gears 23.

[0028] In practical use, when the partition plate 3 needs to be rotated to an upward horizontal or vertical position, the rotation of the main rod 22 inside the main rotating shaft 2 will drive the drive screw 31 to rotate through the action of the bevel gear 23, which will drive the discharge plate 4 to slide on the partition plate 3.

[0029] Preferably, the inner sidewall of the inner plate 21 is rotatably connected to four auxiliary rods 24. One end of each auxiliary rod 24 is fixedly mounted with a spur gear 25, and the other end of both the auxiliary rods 24 and the main rod 22 is fixedly mounted with a pulley 26. A transmission belt 27 is sleeved on the outer side of the pulley 26.

[0030] In practical use, when the main rod 22 needs to rotate, the rotation of the spur gear 25 and the auxiliary rod 24 can cause the auxiliary rod 24 to drive the main shaft 2 to rotate through the linkage of the pulley 26 and the transmission belt 27, which in turn can cause the drive screw 31 to rotate.

[0031] Preferably, an inner ring 6 is fixedly installed on one side of the inner wall of the grinding box 1, and an inner gear ring 61 and an outer gear ring 62 are fixedly installed on one side of the inner ring 6 respectively. Both the inner gear ring 61 and the outer gear ring 62 mesh with the spur gear 25.

[0032] In practical use, when the partition plate 3 rotates to the upward horizontal position, the gear on the auxiliary rod 24 meshes with the internal gear ring 61, causing the main rod 22 to rotate. This causes the drive screw 31 to rotate and push the discharge plate 4 outward. When the partition plate 3 rotates to the upward vertical position, the gear on the auxiliary rod 24 meshes with the external gear ring 62, causing it to rotate in the opposite direction. This allows the discharge plate 4 on the partition plate 3 to slide downward and retract.

[0033] Preferably, a motor 7 is fixedly installed on the outside of the grinding box 1, and the output end of the motor 7 is fixedly connected to one end of the main rotating shaft 2.

[0034] In practical use, motor 7 is used to drive the main shaft 2 to rotate inside the grinding box 1, thereby driving the partition plate 3 to rotate inside the grinding box 1.

[0035] 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.
