Description

Technical Field

[0001] This utility model relates to the field of anti-rust spraying technology, specifically to an auxiliary structure for applying an anti-rust coating to the surface of a stamping sheet. Background Technology

[0002] As a key component of equipment such as motors, the application of an anti-rust coating to the laminations is a crucial step in ensuring equipment performance. The anti-rust coating isolates the laminations from corrosive media such as air and moisture, delaying oxidation and rust formation, and extending the equipment's lifespan. This process, achieved through spray coating, forms a protective film that ensures the laminations maintain structural stability and electrical conductivity under complex operating conditions.

[0003] Utility model patent CN223024178U discloses a rotor lamination. The rotor lamination includes a rotor lamination body with multiple guide groove groups (eight groups) arranged in a circular array on its surface. A central shaft hole is located at the center of the rotor lamination body. The inner wall of the central shaft hole has a square-shaped protrusion with chamfered corners at its protruding parts. A groove connects the protrusion to the central shaft hole, and the inner wall of the central shaft hole also has a misalignment prevention groove. By providing the protrusion, groove, and misalignment prevention groove on the inner wall of the central shaft hole, not only is the recognizability improved, facilitating accurate installation of the rotor lamination body, but it also prevents damage to the key and groove due to misalignment, and enhances the installation stability of the rotor lamination body.

[0004] When the rotor laminations are hung up for rust-preventive coating spraying, the laminations are thin and are prone to swaying under the spraying pressure. This swaying can cause the laminations to collide with each other or shift in position, which may not only affect the uniformity of the coating, but also cause damage to the surface of the laminations due to the collision, thus affecting the subsequent use effect. In view of this, we propose an auxiliary structure for applying rust-preventive coating to the surface of the laminations. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: The anti-rust coating on the surface of the punch sheet is applied to an auxiliary structure, including a cable. Several hanging rods for hanging the punch sheet are installed on the cable. A hanging rod is horizontally provided at the bottom end of the hanging rod. The punch sheet is hung on the hanging rod. A pressing component for resisting the punch sheet and preventing it from shifting is installed on the hanging rod. The pressing component includes a fixed seat fixed on the hanging rod, a pressure rod hinged to the front end of the fixed seat, and a pressing block hinged to the front end of the pressure rod. By moving the pressure rod, the bottom end of the pressing block can be made to abut against the outer end of the punch sheet hanging on the hanging rod. The fixed base is provided with a pulling assembly, which is used to pull the punch piece to prevent the punch piece from moving along the hanging rod under the abutment of the abutment block. The pulling assembly includes a movable rod that is slidably connected to the fixed base in the vertical direction and an abutment rod that is horizontally fixed to the bottom end of the movable rod. The abutment rod extends into the inner ring of the center hole of the punch piece and abuts against the punch piece under the action of gravity.

[0007] Preferably, a first sleeve is fixed to the top of the boom, and a second sleeve is bolted to the first sleeve, and the cable is clamped by the first sleeve and the second sleeve. In this setup, the clamping degree of the first and second clamps can be adjusted by bolts to securely fix the position of the boom on the cable, while also facilitating the adjustment of the boom spacing.

[0008] Preferably, the hanging rod has a round rod structure, and the end of the hanging rod is inclined upwards. In this design, the round rod structure facilitates the mounting of the laminations, and the upward-sloping design at the end reduces the possibility of the laminations slipping off the end of the rod.

[0010] Preferably, the pressure rod has an arc-shaped rod structure, the front end of the pressure rod is provided with a second end post, the top end of the abutment is provided with a pair of hinge plates, the second end post extends between the two hinge plates, and a second hinge shaft is coaxially provided in the second end post, the second hinge shaft passing through the hinge plate and the second end post; In this configuration, the arc-shaped pressure bar facilitates force transmission, and the second end post is hinged to the hinge plate via the second hinge shaft, allowing the abutment block to adapt to the surface angle of the lamination and ensuring good contact.

[0011] Preferably, a lever is fixed on the outer surface of the pressure rod. The lever has a T-shaped structure and is used to move the pressure rod. In this setting, the T-shaped lever is easy for the operator to grip and apply force, making the operation of the lever more convenient and effortless.

[0012] Preferably, the bottom surface of the abutment is provided with a plurality of protruding ridges, the protruding ridges having a rhomboid structure and protruding from the bottom surface of the abutment, the protruding ridges being used to increase the friction between the abutment and the punch sheet; In this setting, the diamond-shaped protrusions can increase the friction between the abutment and the punch, and reduce the slippage of the punch under the pressing state.

[0013] Preferably, a sleeve hole is provided on the rear top surface of the fixed base, the movable rod passes through the sleeve hole and is slidably connected to the fixed base, and a stop block is fixed at the top of the movable rod, the outer diameter of the stop block being larger than the diameter of the sleeve hole; In this configuration, the sleeve provides a sliding channel for the movable rod, allowing the height of the movable rod to be adjusted flexibly, and the stop prevents the movable rod from falling out of the sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The auxiliary structure for applying the anti-rust coating to the surface of the punch sheet, by setting up a pressing component and a pulling component, can form a bidirectional limit for the punch sheet hanging on the hanging rod. The pressing component's pressing block can press against the outer end of the punch sheet to prevent it from shifting, and the pulling component's pushing rod extends into the inner ring of the punch sheet's central hole and presses against the punch sheet under the action of gravity, preventing the punch sheet from moving along the hanging rod under the action of spraying pressure. The two components work together to limit the swing of the punch sheet, making the punch sheet stable in position during the spraying process, which helps to ensure the uniform application of the anti-rust coating, while reducing the damage to the punch sheet caused by swinging and collision.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0017] Please see Figures 1-4 The auxiliary structure for applying the anti-rust coating to the surface of the stamping pieces includes a cable 100 made of high-strength nylon, capable of supporting the weight of multiple stamping pieces 300. Both ends of the cable 100 are connected to the transmission mechanism of the spraying production line. Driven by the transmission mechanism, the cable 100 can move multiple hanging rods 200 mounted on it along a preset trajectory at a uniform speed, allowing the stamping pieces 300 to sequentially pass through the spraying area to complete the anti-rust coating application. Several hanging rods 200 for attaching the stamping pieces 300 are mounted on the cable 100. These hanging rods 200 are made of 45# steel, possessing good rigidity and load-bearing capacity. A horizontal hanging rod 210 is provided at the bottom of each hanging rod 200, connecting the hanging rod 210 to the hanging rod. The rod 200 is welded and fixed, ensuring a secure connection. The punch 300 is hung on the hanging rod 210. A pressing assembly 400 is installed on the hanging rod 200 to hold the punch 300 in place and prevent it from shifting. The pressing assembly 400 includes a fixed seat 410 fixed to the hanging rod 200, a pressure rod 420 hinged to the front end of the fixed seat 410, and a stop block 430 hinged to the front end of the pressure rod 420. The fixed seat 410 is bolted to the hanging rod 200 for easy installation and disassembly. By moving the pressure rod 420, the bottom end of the stop block 430 abuts against the outer end of the punch 300 hanging on the hanging rod 210, allowing the punch 300 to be held against the hanging rod 210 by the stop block 430, reducing lateral swaying of the punch 300 during spraying. The hanging rod 210 has a round rod structure, with its end angled upwards to prevent the punch 300 from slipping off the end of the hanging rod 210.

[0018] like Figure 1As shown, in this utility model, a first sleeve 220 is fixed to the top of the boom 200. The first sleeve 220 is integrally formed with the boom 200, and the structure is stable. A second sleeve 230 is installed on the first sleeve 220 by bolts. Both the first sleeve 220 and the second sleeve 230 are provided with rubber pads on their inner sides, which can increase the friction with the cable 100 and at the same time avoid damaging the cable 100. The cable 100 is clamped by the first sleeve 220 and the second sleeve 230. The position of the boom 200 on the cable 100 can be adjusted by loosening or loosening the bolts.

[0019] like Figure 3 As shown, specifically, the front end of the fixed base 410 is provided with a hinge groove 412, and the rear end of the pressure rod 420 is provided with a first end post 421. The first end post 421 extends into the hinge groove 412, and a first hinge shaft 422 is coaxially provided in the first end post 421. The first hinge shaft 422 is made of stainless steel and has good rust resistance. The first hinge shaft 422 passes through the fixed base 410 and the first end post 421, so that the pressure rod 420 can rotate flexibly around the first hinge shaft 422, which facilitates the adjustment of the position of the abutment block 430. The pressure rod 420 has an arc-shaped rod structure, which conforms to the direction of force transmission and makes the pressure more stable. The front end of the pressure rod 420 is provided with a second end post 423, and the top of the block 430 is provided with a pair of hinge plates 431. The second end post 423 extends between the two hinge plates 431. A second hinge shaft 424 is coaxially provided in the second end post 423. The second hinge shaft 424 is also made of stainless steel. The second hinge shaft 424 passes through the hinge plates 431 and the second end post 423, so that the block 430 can adapt to the angle of the surface of the stamp 300 and ensure good contact with the stamp 300.

[0020] like Figure 1 and Figure 3 As shown, a lever 425 is further fixed on the outer surface of the pressure rod 420. The lever 425 is welded and fixed to the pressure rod 420, and the connection is reliable. The lever 425 has a T-shaped structure, which makes it easy for the operator to hold and exert force. The lever 425 is used to move the pressure rod 420, making it more convenient to adjust the position of the abutment block 430.

[0021] like Figure 4 As shown, the bottom surface of the abutment block 430 is provided with several protruding ridges 432. The protruding ridges 432 are integrally formed with the abutment block 430, and the structure is sturdy. The protruding ridges 432 are rhomboid in shape and protrude from the bottom surface of the abutment block 430. The protruding ridges 432 are used to increase the friction between the abutment block 430 and the punch 300, and further prevent the punch 300 from sliding under the pressing state.

[0022] In this embodiment, the auxiliary structure for applying the anti-rust coating to the surface of the punch sheet is used as follows: First, by adjusting the bolts on the first jacket 220 and the second jacket 230, the hanging rod 200 is fixed to a suitable position on the cable 100. Then, the punch sheet 300 is hung on the hanging rod 210. The upward-sloping design of the end of the hanging rod 210 can initially prevent the punch sheet 300 from slipping. Next, the operator holds the lever 425 and moves the pressure rod 420, causing the pressure rod 420 to rotate around the first hinge axis 422, which drives the abutment block 430 to move towards the punch sheet 300. Finally, the protruding ridge 432 on the bottom surface of the abutment block 430 abuts against the outer end of the punch sheet 300, stably restricting the punch sheet 300 on the hanging rod 210, and the anti-rust coating spraying operation can then be carried out. Example 2

[0023] To prevent the stamping sheet 300 from tilting due to the downward pressure of the abutment block 430 when it is hung on the hanging rod 210, thus preventing the stamping sheet 300 from moving during spraying, therefore, as Figure 1 and Figure 5 As shown, the fixed base 410 is provided with a pulling assembly 500. The pulling assembly 500 is used to pull the punch 300 to prevent the punch 300 from moving along the hanging rod 210 under the abutment of the abutment block 430. The pulling assembly 500 includes a movable rod 510 that is slidably connected to the fixed base 410 in the vertical direction and an abutment rod 520 that is horizontally fixed to the bottom end of the movable rod 510. The movable rod 510 and the abutment rod 520 are made of carbon steel with high strength. The abutment rod 520 extends into the inner ring of the center hole of the punch 300 and abuts against the punch 300 under the action of gravity. Under the action of gravity of the pulling assembly 500, the punch 300 is opened by the hanging rod 210 and the abutment rod 520. At this time, with the pressing of the abutment block 430, the movement of the punch 300 can be further restricted to avoid the punch 300 shaking due to the spraying pressure.

[0024] Specifically, a sleeve hole 411 is provided on the rear top surface of the fixed base 410. The movable rod 510 passes through the sleeve hole 411 and is slidably connected to the fixed base 410, so that the height of the movable rod 510 can be freely adjusted according to the position of the punch 300. A stop block 511 is fixed at the top of the movable rod 510. The stop block 511 is threadedly connected to the movable rod 510 for easy installation and replacement. The outer diameter of the stop block 511 is larger than the diameter of the sleeve hole 411, which can prevent the movable rod 510 from falling out of the sleeve hole 411.

[0025] In this embodiment, the auxiliary structure for applying the anti-rust coating to the surface of the punch sheet is used by first hanging the punch sheet 300 according to the steps in Embodiment 1 and pressing it with the pressing component 400; then, the movable rod 510 of the pulling component 500 passes through the sleeve hole 411 of the fixed base 410, so that the abutment rod 520 extends into the inner ring of the center hole of the punch sheet 300. Under the gravity of the movable rod 510 and the abutment rod 520, the abutment rod 520 abuts against the inner ring of the punch sheet 300, thus opening the punch sheet 300; at this time, the pressing component 400 and the pulling component 500 cooperate to form a stable limit on the punch sheet 300 from both the inner and outer sides, and then the anti-rust coating can be sprayed.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
