Description

Technical Field

[0001] This utility model relates to the field of rotor processing technology, and specifically to an auxiliary pressing device for rotor processing. Background Technology

[0002] Currently, most rotor blanks are manually loaded and clamped into fixtures for machining on grinding machines. While manual clamping offers high flexibility and allows for better control of the clamping tightness, minimizing damage, it is cumbersome, labor-intensive, and significantly reduces machining efficiency. Furthermore, it is susceptible to human error, lowering production precision. Some rotor blanks are directly clamped into fixtures using gantry cranes or robotic arms. While this improves efficiency, these devices lack flexibility, cannot accommodate rotor blanks of different sizes, and can result in damage from excessive force or improper clamping due to insufficient force.

[0003] Therefore, it is essential for the applicant to improve the technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary pressing device for rotor processing, which features a simple structure, high flexibility, wide applicability, high production precision, and fast processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary pressing device for rotor processing, comprising a body, the body including a vertically arranged support plate and an auxiliary pressing assembly movably connected to the upper end of the support plate, the auxiliary pressing assembly including a pressing middle plate and a pressing top plate and a pressing bottom plate respectively fixedly connected to the upper and lower sides of the pressing middle plate, the pressing middle plate and the support plate being arranged perpendicularly to each other, a pressing connecting part adapted to the pressing top plate and the pressing bottom plate being provided on one side of the pressing middle plate, a plurality of middle plate through holes arranged in a matrix on the pressing connecting part, an elastic pressing structure adapted to it being inserted in the middle plate through holes, a top plate groove and a bottom plate through hole adapted to the elastic pressing structure being provided on the pressing top plate and the pressing bottom plate respectively, the auxiliary pressing assembly including a blank pressing module located on the lower side of the pressing bottom plate, the lower surface of the blank pressing module cooperating with the rotor blank.

[0006] By adopting the above technical solution, the rotor blank is elastically pressed into the fixture through the cooperation of the elastic pressing structure and the blank pressing module in the auxiliary pressing assembly. This avoids the problem of low grinding accuracy caused by excessive downward pressure damaging the rotor blank or insufficient pressing due to insufficient force. It is highly flexible, has high processing efficiency, and is convenient for automated production.

[0007] The present invention is further configured such that: the upper surface of the blank pressing module is a plane and abuts against the lower end of the elastic pressing structure; at least one module groove adapted to the rotor blank is provided in the lower part of the blank pressing module; the cross-section of the module groove is set in an arc shape.

[0008] By adopting the above technical solution, the modular groove can easily fit the upper surface of the rotor blank, thus facilitating the auxiliary pressing assembly to press the rotor blank. The modular groove can be used for rotor blanks of various specifications and sizes, improving the overall applicability of the device.

[0009] The present invention is further configured such that: the elastic pressing structure includes a compression spring and a pressing pin connected to the lower end of the compression spring; the upper end of the compression spring is in contact with the bottom of the groove of the top plate; the pressing pin includes an integral pressing head and a pressing rod; the pressing rod passes through the through hole of the bottom plate and slides up and down in the through hole of the bottom plate; a limiting step adapted to the pressing head is also provided on the upper side of the through hole of the bottom plate.

[0010] By adopting the above technical solution, when the auxiliary pressing assembly presses the rotor blank to be processed downwards, the compression spring is continuously compressed, and the pressing pin moves upwards. Conversely, the pressing pin is reset under the action of the compression spring.

[0011] The present invention is further configured such that: the auxiliary pressing assembly also includes a module clamping cylinder adapted to the blank pressing module; the module clamping cylinder is fixedly connected to the pressing top plate by setting a cylinder pad; the module clamping cylinder is configured as a finger cylinder; the module clamping cylinder is provided with two symmetrical module clamping claws; the two module clamping claws are respectively located on the left and right sides of the blank pressing module; the pressing top plate, the pressing middle plate and the pressing bottom plate are all provided with claw retraction grooves adapted to the module clamping claws on both sides.

[0012] By adopting the above technical solution, the module clamping claw is driven to move by the action of the module clamping cylinder, thereby clamping or releasing the blank pressing module.

[0013] The present invention is further configured such that: the elastic pressing structure is also provided with an electromagnet adapted to the blank pressing module, and the blank pressing module is embedded with a module magnet adapted to the pressing pin. When the electromagnet is energized, it and the module magnet are like poles and repel each other. When the power is off, the pressing pin and the module magnet attract each other.

[0014] By adopting the above technical solution, the magnetic field generated by the electromagnet when it is energized is in the same direction as the magnetic field of the module magnet, thus repelling each other and causing the upper surface of the blank pressing module to separate from the pressing pin. When the electromagnet is de-energized, there is no magnetic field, and the module magnet and the pressing pin attract each other, causing the blank pressing module to adhere to the lower surface of the pressing pin. This ensures that the blank pressing module will adhere to the lower part of the pressing pin after the worker leaves work and the power is turned off, and will not be lost. It also ensures electrical safety and eliminates the need for module clamping cylinders and module clamping claws, thus reducing the overall structure.

[0015] The present invention is further configured as follows: a lateral pressing cylinder adapted to the support plate is arranged laterally thereon, the piston rod of the lateral pressing cylinder faces the blank pressing module, and a lateral pressing block adapted to the rotor blank is fixedly connected to the piston rod. A lateral cylinder slot adapted to the lateral pressing cylinder is opened on the support plate, and the lateral pressing cylinder is inserted into the lateral cylinder slot. The lateral pressing cylinder is fixedly connected to the support plate by a lateral cylinder seat. The lateral cylinder seat is arranged in an L-shaped structure. A cylinder fixing groove and a support fixing hole adapted to the lateral pressing cylinder and the support plate are opened on the lateral cylinder seat respectively. The cylinder fixing groove is arranged in a long strip shape.

[0016] By adopting the above technical solution, the lateral pressing cylinder avoids lateral displacement of the rotor blank, ensures that the rotor blank is pressed and clamped in place, improves the machining accuracy of the rotor blank, and improves product quality.

[0017] The present invention is further configured such that: a plurality of adjustment slots adapted to the support plate are provided on the other side of the pressing plate, the adjustment slots are elongated, and adjustment bolts adapted to them are inserted in the adjustment slots. The lower end of the adjustment bolts is fixedly connected to the upper end of the support plate, and the upper end of the support plate is provided with fixing screw holes adapted to the adjustment bolts.

[0018] By adopting the above technical solution, the distance between the support plate and the blank pressing module can be controlled by adjusting the bolts, thereby adapting to the processing needs of rotors of different sizes and improving the applicability of the main body.

[0019] The present invention is further configured such that: the lower end of the support plate is connected to the moving device, which can be any one of a truss, a robot, a pneumatic actuator, or an electric actuator.

[0020] By adopting the above technical solution, the moving device drives the support plate to move, thereby driving the auxiliary pressing component to press the rotor blank into the fixture, and then resets it after pressing.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The rotor blank is elastically pressed into the fixture by the cooperation of the elastic pressing structure and the blank pressing module in the auxiliary pressing assembly. This avoids the problem of low grinding accuracy caused by excessive downward pressure damaging the rotor blank or insufficient pressing due to insufficient force. It is highly flexible, efficient, and easy to automate production.

[0023] 2. The module clamping cylinder moves to drive the module clamping claw, which clamps or releases the blank pressing module. It releases when pressed down and clamps when reset. When the electromagnet is energized, it repels the module magnet due to their similar polarities. When the power is off, the pressing pin attracts the module magnet, so that the blank pressing module is released when the power is off when pressed down and attracted when the power is on when reset.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1: This example discloses an auxiliary pressing device for rotor processing, such as... Figures 1 to 4 As shown, it includes a body, which includes a vertically arranged support plate 1 and an auxiliary pressing assembly movably connected to the upper end of the support plate 1. The lower end of the support plate 1 is connected to a moving device, which can be any one of a truss, a robot, a pneumatic actuator, or an electric actuator. The moving device drives the support plate 1 to move, thereby driving the auxiliary pressing assembly to press the rotor blank into the fixture. After pressing into place, it is reset.

[0035] The auxiliary pressing assembly includes a pressing middle plate 2 and a pressing top plate 3 and a pressing bottom plate 4, which are fixedly connected to the upper and lower sides of the pressing middle plate 2, respectively. The pressing middle plate 2 and the support plate 1 are arranged perpendicularly to each other. A pressing connection part adapted to the pressing top plate 3 and the pressing bottom plate 4 is provided on one side of the pressing middle plate 2. Several middle plate through holes 21 arranged in a matrix are opened on the pressing connection part. An elastic pressing structure 5 adapted to it is inserted in the middle plate through hole 21. The pressing top plate groove 31 and the pressing bottom plate 4 are respectively opened on the pressing top plate groove 31 and the pressing bottom plate through hole 41 adapted to the elastic pressing structure 5. The elastic pressing structure 5 achieves the effect of elastic design, avoiding the problem of damage to the surface of the rotor blank or improper pressing and clamping caused by excessive or insufficient force during the pressing process of the auxiliary pressing assembly, thereby improving the rotor machining accuracy.

[0036] The elastic pressing structure 5 includes a compression spring 51 and a pressing pin 52 connected to the lower end of the compression spring 51. The upper end of the compression spring 51 is in contact with the bottom of the groove 31 in the top plate. The pressing pin 52 includes an integral pressing head 521 and a pressing rod 522. The pressing rod 522 passes through the bottom plate through hole 41 and slides up and down in the bottom plate through hole 41. When the auxiliary pressing assembly presses the rotor blank to be processed downward, the compression spring 51 is continuously compressed and the pressing pin 52 moves upward. Conversely, the pressing pin 52 is reset under the action of the compression spring 51. A limiting step 42 adapted to the pressing head 521 is also provided on the upper side of the bottom plate through hole 41. The limiting step 42 and the pressing head 521 cooperate with each other to prevent the pressing pin 52 from coming out of the bottom plate through hole 41 and ensure the reliability of the pressing action.

[0037] The auxiliary pressing assembly includes a blank pressing module 6 located on the lower side of the pressing base plate 4. The upper surface of the blank pressing module 6 is flat and abuts against the lower end of the elastic pressing structure 5. At least one module groove 61 adapted to the rotor blank is opened in the lower part of the blank pressing module 6. The cross-section of the module groove 61 is set with an arc structure. The arc structure facilitates fitting the upper surface of the rotor blank, thereby facilitating the auxiliary pressing assembly to press the rotor blank. The module groove 61 can be used for rotor blanks of various specifications and sizes, improving the overall applicability of the device.

[0038] The auxiliary pressing assembly also includes a module clamping cylinder 7 adapted to the blank pressing module 6. The module clamping cylinder 7 is fixedly connected to the pressing top plate 3 by setting a cylinder pad 71. The module clamping cylinder 7 is set as a finger cylinder, and two symmetrical module clamping claws 72 are set on the module clamping cylinder 7. The two module clamping claws 72 are located on the left and right sides of the blank pressing module 6, respectively. The module clamping cylinder 7 drives the module clamping claws 72 to move, so that the module clamping claws 72 clamp the blank. The blank pressing module 6 performs clamping or releasing actions. When the auxiliary pressing component presses the rotor blank, the module clamping cylinder 7 releases the blank pressing module 6. When detaching from the rotor blank, the module clamping cylinder 7 clamps the blank pressing module 6 so that it can smoothly detach from the surface of the rotor blank. The pressing top plate 3, the pressing middle plate 2, and the pressing bottom plate 4 are all provided with claw relief grooves 23 that are adapted to the module clamping claws 72. The claw relief grooves 23 facilitate the module clamping claws 72 to perform clamping or releasing actions.

[0039] A lateral pressing cylinder 8 is horizontally arranged on the support plate 1 and is adapted to it. The piston rod of the lateral pressing cylinder 8 faces the blank pressing module 6, and a lateral pressing block 81 adapted to the rotor blank is fixedly connected to the piston rod. The lateral pressing cylinder 8 prevents the rotor blank from shifting laterally, ensures that the rotor blank is pressed and clamped in place, improves the machining accuracy of the rotor blank, and improves the product quality.

[0040] The support plate 1 has a side cylinder slot adapted to the side pressing cylinder 8. The side pressing cylinder 8 is inserted into the side cylinder slot and is fixedly connected to the support plate 1 by a side cylinder seat 82. The side cylinder seat 82 is L-shaped and has a cylinder fixing groove 821 and a support fixing hole adapted to the side pressing cylinder 8 and the support plate 1, respectively. The cylinder fixing groove 821 is elongated and the elongated fixing groove facilitates the adjustment of the position and range of motion of the side cylinder.

[0041] On the other side of the pressing plate 2, there are several adjustment slots 22 that are adapted to the support plate 1. The adjustment slots 22 are elongated and are fitted with adjustment bolts. The lower end of the adjustment bolts is fixedly connected to the upper end of the support plate 1. The upper end of the support plate 1 is provided with fixing screw holes that are adapted to the adjustment bolts. The distance between the support plate 1 and the blank pressing module 6 is controlled by the adjustment bolts to adapt to the processing needs of rotors of different sizes.

[0042] The working process is as follows: When the rotor blank is pressed and clamped, the moving device drives the main body to move downward, so that the auxiliary pressing component presses downward. When the lower surface of the blank pressing module 6 in the auxiliary pressing component abuts against the upper surface of the rotor blank, the module clamping cylinder 7 is activated, causing the module clamping claw 72 to release the blank pressing module 6. The auxiliary pressing component continues to move downward and press the rotor blank, so that the rotor blank is pressed into the fixture. At the same time, the compression spring 51 is compressed during pressing to avoid excessive downward pressure that could damage the rotor blank, until the rotor blank is completely pressed into place. After pressing is completed, the moving device drives the main body to reset. During the reset process, the module clamping cylinder 7 clamps the blank pressing module 6 to remove it from the surface of the patented blank, making it easier for the grinding machine to perform machining.

[0043] Example 2: The difference between this example and Example 1 is that, as shown in Example 2... Figures 5 to 8 As shown, the elastic pressing structure 5 is also equipped with an electromagnet 53 adapted to the blank pressing module 6. The blank pressing module 6 is embedded with a module magnet 62 adapted to the pressing pin 52. When the electromagnet 53 is energized, the magnetic field direction is the same as that of the module magnet 62, so they repel each other, causing the upper surface of the blank pressing module 6 to separate from the pressing pin 52. When the electromagnet 53 is de-energized, there is no magnetic field, and the module magnet 62 and the pressing pin 52 attract each other, so that the blank pressing module 6 is attached to the lower surface of the pressing pin 52. This ensures that the blank pressing module 6 will be attached to the lower part of the pressing pin 52 after the worker leaves work and the power is turned off, and will not be lost. It also ensures electrical safety and eliminates the need for module clamping cylinder 7 and module clamping claw 72, thus reducing the overall structure.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
