Description

Technical Field

[0001] The invention relates to an auxiliary tool for surface treatment of a polyurethane plate and a use method thereof. Background Art

[0002] The rotor is a key component of the permanent magnet machine. In order to prevent high-order harmonics from generating eddy current losses on the surface of the rotor core, the surface of the motor rotor core is not processed. This requires improving the straightness and axis verticality during the rotor punching process.

[0003] In the past, rotor lamination stacking was done manually, which required very high operating skills from workers. Moreover, the accuracy of manual stacking could not meet the use requirements of the above-mentioned rotors. At the same time, manual stacking was time-consuming, labor-intensive and inefficient. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an auxiliary tooling for surface treatment of a polyurethane plate and a method for using the same. When the polyurethane plate is pushed onto a treatment table, as the roller abuts against the surface of the polyurethane plate and rotates between two connecting rods, the friction between the polyurethane plate and the surface of the treatment table can be reduced, saving the staff's effort in pushing the polyurethane plate and improving work efficiency. As the power output end of the telescopic cylinder pulls the connecting strip, the roller slides in the slide groove along the length direction of the slide groove, thereby driving the two moving blocks to approach each other, causing the connecting strip to move with it, driving the two limit plates to approach each other, reducing the positioning area, causing the limit plate to abut against the polyurethane plate, and fixing the polyurethane plate, so that the staff can process the surface of the polyurethane plate, thereby improving the stability of the polyurethane plate during the processing process.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an auxiliary tooling for surface treatment of a polyurethane plate, comprising a base, a support frame, two steel frames, a limit clamping assembly, a treatment table and a friction reduction unit, wherein the support frame is arranged on the base, the two steel frames are transversely arranged in the support frame, and the treatment table is arranged on the surfaces of the two steel frames. The polyurethane plate to be processed is placed on the surface of the processing table after passing through the friction reduction unit, and the polyurethane plate is clamped by the limit clamping component to achieve processing of the surface of the fixed polyurethane plate.

[0006] As a preferred technical solution of the present invention, a slide groove is opened inward on one side of the opposite sides of the two steel frames, and the limit clamping assembly includes a moving wheel arranged in the slide groove, a connecting rod is inserted in the moving wheel, and a moving block is connected to the end of the connecting rod away from the moving wheel.

[0007] As a preferred technical solution of the present invention, a support plate is provided on the upper surface of the moving block, the cross section of the support plate is L-shaped, and a limit plate for abutting the polyurethane plate is provided on the side of the support plate facing the polyurethane plate.

[0008] As a preferred technical solution of the present invention, the number of the moving blocks is four, each two of which are not adjacent to each other, and a connecting strip is provided between the moving blocks located on the lower surface of the same support plate.

[0009] As a preferred technical solution of the present invention, two connecting bars are provided, and a mounting plate is provided on the adjacent side of the two connecting bars. A telescopic cylinder is provided on the mounting plate, and a power output end of the telescopic cylinder is connected to the connecting bar.

[0010] As a preferred technical solution of the present invention, a hanging rod is inserted in the slide groove, the hanging rod extends outside the steel frame, two springs are arranged on the hanging rod, and the two springs are respectively connected to the moving bar through a hanging plate.

[0011] As a preferred technical solution of the present invention, an adjusting component for adjusting the height of the steel frame is provided in the supporting frame, and the adjusting component includes a lifting plate arranged in the lower surface of the steel frame, and the lifting plate is installed in the supporting frame. An adjusting screw is inserted in the supporting frame, and the adjusting screw also passes through the lifting plate, and a positioning bolt is provided on the adjusting screw.

[0012] As a preferred technical solution of the present invention, the friction reduction unit includes grooves opened at the feed port and the discharge port of the processing table, and two connecting rods and rollers are arranged in the grooves.

[0013] As a preferred technical solution of the present invention, the two connecting rods are respectively arranged on both sides of the groove, and the roller is arranged between the two connecting rods.

[0014] A method for using an auxiliary tooling for surface treatment of a polyurethane plate, the specific steps are as follows: S1, placing the polyurethane plate to be processed on the processing table through the processing table feed port, at which time the lower surface of the polyurethane plate will abut against the roller, and as the roller rotates between the two connecting rods, the polyurethane plate moves to the surface of the processing table; S2. Before the polyurethane plate moves to the surface of the processing table, the telescopic cylinder is started, and the power output end of the telescopic cylinder drives the connecting strip, and as the moving wheel slides in the slide groove along the length direction of the slide groove, the moving block moves, thereby driving the connecting strip to follow the movement; S3. When the two moving blocks are driven by the telescopic cylinder to move in opposite directions, the supporting plate is driven to follow the movement, so that the two limit plates move away from each other, and a positioning area for clamping the polyurethane plate is formed between the two limit plates; S4. As the polyurethane plate enters the positioning area, when the telescopic cylinder stops pushing the connection bar, the spring deforms and reacts on the moving block, so that the two connection bars drive the limit plates to approach each other first, reduce the positioning area, and fix the polyurethane plate; S5. The surface of the fixed polyurethane plate is treated.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0019] Example: like Figure 1 - Figure 6 As shown, this embodiment proposes an auxiliary tooling for surface treatment of a polyurethane plate, comprising a base 1, a support frame 2, two steel frames 3, a limit clamping assembly, a processing table 4 and a friction reduction unit, wherein the support frame 2 is arranged on the base 1, the two steel frames 3 are transversely arranged in the support frame 2, and the processing table 4 is arranged on the surfaces of the two steel frames 3, wherein the polyurethane plate to be treated is placed on the surface of the processing table 4 after passing through the friction reduction unit, and as the limit clamping assembly clamps the polyurethane plate, the surface of the fixed polyurethane plate is processed; When the polyurethane plate is pushed onto the processing table 4, as the roller 22 abuts against the surface of the polyurethane plate and rotates between the two connecting rods 21, the friction between the polyurethane plate and the surface of the processing table 4 can be reduced, saving the staff's effort to push the polyurethane plate and improving work efficiency. As the power output end of the telescopic cylinder 13 pulls the connecting strip 11, the roller 22 slides in the slide groove 5 along the length direction of the slide groove 5, thereby driving the two moving blocks 8 to approach each other, allowing the connecting strip 11 to move with it, driving the two limit plates 10 to approach each other, reducing the positioning area, and allowing the limit plates 10 to abut against the polyurethane plate to fix the polyurethane plate, so that the staff can process the surface of the polyurethane plate, thereby improving the stability of the polyurethane plate during processing.

[0020] Among them, the opposite sides of the two steel frames 3 are both provided with a slide groove 5 inwardly, and the limit clamping assembly includes a moving wheel 6 arranged in the slide groove 5. When the moving wheel 6 moves in the slide groove 5, the two moving blocks 8 can be driven to approach or move away from each other through the connection of the connecting rod 7. The connecting rod 7 is inserted in the moving wheel 6, and the moving block 8 is connected to the end of the connecting rod 7 away from the moving wheel 6. A support plate 9 is provided on the upper surface of the moving block 8. The cross section of the support plate 9 is L-shaped. The support plate 9 is provided with a limit plate 10 for abutting the polyurethane plate on the side facing the polyurethane plate. A positioning area for clamping and fixing the polyurethane plate is formed between the limit plates 10. As the moving block 8 moves, the limit plates 10 are driven to approach or move away from each other, thereby adjusting the size of the positioning area. It can be adjusted according to the size of the polyurethane plate, which increases practicality. The number of the moving blocks 8 is four, and a connecting bar 11 is provided between each two non-adjacent moving blocks 8 located on the lower surface of the same support plate 9. The support plate 9 is supported by the connecting bar 11, and as the telescopic cylinder 13 pushes the connecting bar 11, the moving block 8 is driven to move, and then the support plate 9 and the limit plate 10 are driven to move. The number of the connecting bars 11 is two, and a mounting plate 12 is provided on the side close to the two connecting bars 11. The mounting plate 12 is provided with a telescopic cylinder 13, and the power output end of the telescopic cylinder 13 is connected to the connecting bar 11. The telescopic cylinder 13 is a prior art and will not be described in detail here. The number of the telescopic cylinder 13 is two, and the power output ends of the two telescopic cylinders 13 are respectively output to two different connecting bars 11, thereby driving the two moving blocks 8 to move. A hanging rod 14 is inserted in the slide groove 5, and the hanging rod 14 extends to the outside of the steel frame 3. Two springs 15 are arranged on the hanging rod 14, and the two springs 15 are connected to the moving bar through the hanging plates 16 respectively. There are two hanging rods 14, and springs 15 are arranged on both sides of each hanging rod 14, which are respectively connected to the connecting bar 11 through the hanging plates 16. When the telescopic cylinder 13 drives the moving block 8 to drive the connecting bar 11 to move, the two springs 15 will be stretched. After the telescopic cylinder 13 cancels the power, the two springs 15 are deformed, thereby pulling the two moving blocks 8, so that the two moving blocks 8 are close to each other, so that the limit plate 10 abuts against the polyurethane plate, and the polyurethane plate is fixed.

[0021] Furthermore, an adjusting component for adjusting the height of the steel frame 3 is provided in the support frame 2, and the adjusting component includes a lifting plate 17 arranged in the lower surface of the steel frame 3, and the lifting plate 17 is installed in the support frame 2. An adjusting screw 18 is inserted in the support frame 2, and the adjusting screw 18 also passes through the lifting plate 17, and a positioning bolt 19 is provided on the adjusting screw 18. After the lifting plate 17 moves on the adjusting screw 18, the lifting plate 17 is fixed with the positioning bolt 19 to adjust the working height of the processing table 4, further improving the convenience. The friction reduction unit includes a groove 20 opened at the feeding port and the discharging port of the processing table 4, and two connecting rods 21 and a roller 22 are arranged in the groove 20. The two connecting rods 21 are respectively arranged on both sides of the groove 20, and the roller 22 is arranged between the two connecting rods 21. When the polyurethane plate passes through the feeding port and the discharging port of the processing table 4, the roller 22 will abut against the lower surface of the polyurethane plate. As the roller 22 rotates between the two connecting rods 21, the friction between the polyurethane plate and the processing table 4 can be reduced, saving the staff's effort to push the polyurethane plate and speeding up work efficiency.

[0022] A method for using an auxiliary tooling for surface treatment of a polyurethane plate, the specific steps are as follows: S1, placing the polyurethane plate to be processed on the processing table 4 through the feeding port of the processing table 4, at this time, the lower surface of the polyurethane plate will abut against the roller 22, and as the roller 22 rotates between the two connecting rods 21, the polyurethane plate moves to the surface of the processing table 4; S2, before the polyurethane plate moves to the surface of the processing table 4, the telescopic cylinder 13 is started, and the power output end of the telescopic cylinder 13 drives the connecting bar 11, and as the roller 22 slides in the slide groove 5 along the length direction of the slide groove 5, the moving block 8 moves, thereby driving the connecting bar 11 to follow the movement; S3, when the two moving blocks 8 move in opposite directions under the drive of the telescopic cylinder 13, the supporting plate 9 is driven to follow the movement, so that the two limiting plates 10 move away from each other, and a positioning area for clamping the polyurethane plate is formed between the two limiting plates 10; S4, as the polyurethane plate enters the positioning area, when the telescopic cylinder 13 cancels the push on the connecting strip 11, the spring 15 is deformed, and the reaction force is applied to the moving block 8, so that the two connecting strips 11 drive the limiting plates 10 to approach each other first, reduce the positioning area, and fix the polyurethane plate; S5. The surface of the fixed polyurethane plate is treated. After the treatment, as the telescopic cylinder 13 is pushed again, the moving block 8 drives the supporting plate 9 to move, so that the limiting plate 10 is separated from the polyurethane plate, and the treated polyurethane plate can be pulled out.
