Description

Technical Field

[0001] This utility model belongs to the field of balancing machine technology, and in particular relates to a three-station combined fully automatic material reduction balancing machine. Background Technology

[0002] A balancing machine is an instrument used to measure rotor imbalance. It is a type of hard-bearing balancing machine with a very stiff swing frame. The measurement results of the dynamic balancing machine are used to correct the rotor imbalance, so that the vibration generated by the rotor during rotation or the vibration acting on the bearing is reduced to an allowable range, thereby reducing vibration, improving performance and improving product quality.

[0003] The surface burrs generated during the processing of existing rotors (such as stamping, casting, cutting, etc.) not only increase the imbalance, but may also cause friction, heat generation, or even damage to the winding insulation layer at high speeds. However, existing balancing equipment focuses on correcting the rotor balance quality and does not include the removal of burrs on the rotor surface in the balancing correction process. Utility Model Content

[0004] This invention addresses the problem that surface burrs generated during rotor processing (such as stamping, casting, and cutting) not only increase imbalance but may also cause friction, heat generation, and even damage to the winding insulation layer at high speeds. However, existing balancing equipment mainly focuses on correcting rotor balance quality and does not incorporate burr removal from the rotor surface into the balancing correction process. The following technical solution is proposed:

[0006] The enclosure is used to provide a space for workpiece processing;

[0007] Mounting brackets are used to support workpieces that need to be processed;

[0008] A grinding assembly includes a drive unit, a mounting box, an elastic element, and a grinding plate. The drive unit is connected to the housing, the mounting box is connected to the drive unit, the elastic element is connected to the mounting box, and the grinding plate is disposed inside the mounting box. The grinding plate comes into contact with the rotor under the action of the drive unit.

[0009] As a preferred embodiment of the above technical solution, an installation component is also included, the installation component comprising:

[0010] Insertion block and card slot, wherein the insertion block is used to be inserted into the card slot;

[0011] The second elastic element has one end connected to the mounting box and the other end connected to the insertion block, and is used to push the insertion block to move.

[0012] As a preferred embodiment of the above technical solution, the mounting bracket is connected to a bearing, which is used to support both ends of the rotor.

[0013] As a preferred embodiment of the above technical solution, a positioning component is further included, the positioning component comprising:

[0014] The upper pressure block and side plate are used to limit the ends of the rotor;

[0015] A sliding block, connected to the upper pressure block, is used to push the upper pressure block and the side plate to move.

[0016] As a preferred embodiment of the above technical solution, the positioning component further includes a rectangular block and a rectangular plate, both of which are disposed at the top of the mounting frame.

[0017] As a preferred embodiment of the above technical solution, a guide post is sandwiched between the rectangular block and the rectangular plate, and an adjusting rod is connected inside the rectangular plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) This utility model can grind the surface burrs and other impurities of the rotor being balanced by setting the grinding component and the installation component, effectively removing the imbalance on the rotor surface and ensuring that the ground rotor meets the actual use requirements. At the same time, the installation component facilitates the quick disassembly and replacement of the easily worn grinding plate, ensuring a continuous and efficient grinding effect, and ultimately achieving a smooth and balanced rotor surface.

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example 1

[0029] This utility model provides a three-station combined fully automatic material reduction balancing machine. The three-station combined fully automatic material reduction balancing machine includes a housing 1, a mounting frame 2, and a grinding assembly. The housing 1 provides a place for workpiece processing; the mounting frame 2 supports the workpiece to be processed; the grinding assembly includes a drive component 3, a mounting box 4, elastic elements 5, and a grinding plate 6. The drive component 3 is fixedly installed inside the housing 1, and the mounting box 4 is fixedly connected to the top of the drive component 3. Several sets of elastic elements 5 are symmetrically arranged inside the mounting box 4, and the grinding plate 6 is slidably installed inside the mounting box 4. The bottom ends of the multiple sets of elastic elements 5 are all fixedly connected to the bottom of the inner wall of the mounting box 4, and the top ends of the multiple sets of elastic elements 5 are all in contact with the bottom end of the grinding plate 6. Under the action of the drive component 3, the grinding plate 6 can contact the rotor 17.

[0030] By moving the mounting box 4 upward, the position of the grinding plate 6 is raised, and the grinding plate 6 is moved to the bottom of the rotor 17, so that the rotating rotor 17 comes into contact with the grinding plate 6, and the outer surface of the rotor 17 is ground to meet the actual use requirements.

[0031] In use, the drive unit 3 is energized to push the mounting box 4 upward. As the mounting box 4 moves upward, the grinding plate 6 moves upward synchronously, so that the grinding plate 6 comes into contact with the bottom of the rotor 17. As the rotor 17 continues to rotate, the grinding plate 6 continuously contacts the rotor 17 and scrapes it, thereby removing burrs and other impurities from the outer surface of the rotor 17. At the same time, under the action of the elastic element 5, it is ensured that the rotor 17 and the grinding plate 6 maintain appropriate elastic contact, avoiding excessive squeezing pressure between the grinding plate 6 and the rotor 17, which could cause damage.

[0032] It is worth noting that the rotation of rotor 17 is driven by friction. In practical use, the annular belt is usually made of rubber or silk material, with a circular cross-section, smooth surface and a certain degree of elasticity. By tightly wrapping the annular belt around the drive wheel of the motor and the outer surface of rotor 17, when the motor works and drives the drive wheel to rotate, the annular belt will drive rotor 17 to rotate synchronously. The above are all existing technologies and will not be elaborated further here.

[0033] To facilitate quick replacement of the worn grinding plate 6, the mounting assembly includes a plug 7, an elastic element 8, and a retaining plate groove 9. The plug 7 is specifically designed to be T-shaped. One end of the elastic element 8 is fixedly connected to the inside of the mounting box 4, and the other end of the elastic element 8 is connected to the plug 7. The grinding plate 6 has a retaining plate groove 9 inside, and one end of the plug 7 is inserted into the retaining plate groove 9. By pulling the insert blocks 7 to both sides of the mounting box 4, the insert blocks 7 gradually slide out from the inside of the mounting box 4, causing the elastic element 2 8 to be stretched and deformed. Then, the grinding plate 6 is placed inside the mounting box 4. Under the support of the elastic element 1 5 inside the mounting box 4, the grinding plate 6 is made flush with the top of the mounting box 4. Then, the insert blocks 7 are released, and the stretched and deformed elastic element 2 8 releases its elastic potential energy, causing the insert blocks 7 to move in the opposite direction, so that the end of the insert blocks 7 is inserted into the retaining plate groove 9, and the grinding plate 6 is locked inside the mounting box 4, preventing it from coming out of the mounting box 4. When it is necessary to replace the worn grinding plate 6, the above operation is reversed, and the worn grinding plate 6 can be removed and replaced with a new grinding plate 6.

[0034] Specifically, in this embodiment, the driving component 3 can be configured as an electric push rod or a cylinder, the elastic component 1 5 and the elastic component 2 8 are both configured as springs, and the surface material of the grinding plate 6 is the same as that of the grinding wheel in the prior art, so as to achieve the grinding effect.

[0035] In order to keep rotor 17 stable during rotation, such as Figure 2 and Figure 5 As shown, a bearing 21 is installed on the mounting frame 2. The bearing 21 is used to support both ends of the rotor 17. The positioning assembly includes an upper pressure block 10, a side plate 11, a sliding block 12, a rectangular block 13, and a rectangular plate 14. The rectangular block 13 and the rectangular plate 14 are both fixedly installed on the top of the mounting frame 2. A guide post 15 is fixedly connected between the rectangular block 13 and the rectangular plate 14. The sliding block 12 is slidably installed on the outer surface of the guide post 15. An adjusting rod 16 is rotatably connected inside the rectangular plate 14. The adjusting rod 16 is threadedly connected to the upper pressure block 10.

[0036] The rotor 17 to be ground is placed on two sets of bearings 21. Under the action of the sliding block 12 and the guide post 15, when the adjusting rod 16 rotates, the upper pressure block 10 is driven to move closer to the rotor 17 through the threaded connection. As the adjusting rod 16 continues to rotate, the side plate 11 moves to the end of the rotor 17, and the upper pressure block 10 is sleeved on the outer surface of the end of the rotor 17 to limit the end of the rotor 17. The above operation is repeated to limit both ends of the rotor 17, ensuring that the rotor 17 will not be displaced or shaken during the grinding operation, thus ensuring the stability of the rotor 17 during the grinding process and improving the quality and efficiency of grinding.

[0037] Working principle: In practical use, the rotor 17 to be ground is placed on the bearing 21, and the adjusting rod 16 is rotated to drive the upper pressure block 10 towards the end of the rotor 17 through the threaded connection. The adjusting rod 16 is then rotated until the side plate 11 contacts the end of the rotor 17, and the upper pressure block 10 is fitted onto the outer surface of the end of the rotor 17, thus limiting one end of the rotor 17. This operation is repeated to restrict both ends of the rotor 17, ensuring that the rotor 17 does not wobble or shift during grinding, thus improving the stability of the rotor 17 during grinding. Then, a ring belt is tightly fitted around the rotor 17 and the motor drive. When the motor drives the drive wheel to rotate, the rotor 17 rotates synchronously through the action of the annular belt. Then, the drive component 3 is energized and pushes the mounting box 4 to move upward. As the mounting box 4 rises, it drives the grinding plate 6 to move upward synchronously, so that the grinding plate 6 comes into contact with the bottom of the rotor 17. When the rotor 17 rotates, the grinding plate 6 and the outer side of the rotor 17 rub against each other, thereby removing burrs and other impurities from the outer surface of the rotor 17. At the same time, under the action of the elastic component 5, it is ensured that the grinding plate 6 and the rotor 17 maintain appropriate elastic contact, so as to avoid excessive pressure between the grinding plate 6 and the rotor 17, which may cause damage.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
