They are characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used basic mechanical parts and are in great demand. A large amount of iron filings will be generated during the production and preparation process of fasteners.

[0016] The beneficial effects of the present invention are as follows: 1. The fastener cleaning machine described in the present invention clamps each fastener by starting the clamping assembly, and after the fastener is clamped, the fastener is placed inside the cleaning frame. Then, when enough fasteners are placed inside the cleaning frame, the sliding guide rail is started to drive the cleaning frame to move to the top of the positioning frame, and then the positioning frame is started to slide upward. The upward movement of the positioning frame will drive the positioning frame to soak the cleaning agent stored in the liquid storage tank, and then the positioning frame will cover the entire cleaning frame, and the cleaning agent in the positioning frame will flow into the cleaning frame, thereby cleaning the dirt and metal debris attached to the circumferential surface of the fastener, thereby achieving an automatic cleaning effect.

Therefore, the third hydraulic cylinder is started to drive the push plate at its output end to scrape the metal deposits inside the positioning frame. After scraping to the top of the sealing plate, the sealing plate is driven to move by starting the fourth hydraulic cylinder, so that the metal deposits fall into the metal precipitation frame inside the working box, thereby ensuring the cleaning effect of the cleaning agent and improving the cleaning quality of the cleaning agent.

[0022] 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 explained below in conjunction with specific implementation methods. Example

[0023] like Figures 1 to 10As shown, a fastener cleaning machine described in an embodiment of the present invention includes a working box 1, the upper surface of which is fixedly connected to a top frame 2; two sliding guide rails 510 fixedly connected to the inside of the working box 1, the two sliding guide rails 510 are slidably connected to sliding plates 59, the two sliding plates 59 are fixedly connected to the same cleaning frame 5, and a plurality of fixing holes 51 are provided on the surface of the cleaning frame 5; a positioning frame 7 slidably arranged inside the working box 1, and a liquid storage tank 72 is provided in the positioning frame 7; two second guide rails 61 fixedly connected to the top wall of the top frame 2, each of the second guide rails 61 is slidably connected to a clamping assembly, and the clamping assembly is used to clamp large fasteners; and a cleaning member arranged on the inner wall of the working box 1, and the cleaning member is used to clean the fasteners after cleaning.

[0024] Specifically, when cleaning large fasteners such as ships, iron filings on the surface of large fasteners are cleaned by using a cleaning brush. However, during the cleaning process of the fasteners, the operator needs to be exposed to harmful cleaning agents sprayed on the surface of the fasteners, which will threaten the health of the body, and long-term manual operation is prone to fatigue. Secondly, the cleaning efficiency is low, which is difficult to meet the needs of efficient and fast production, and increases production costs. In addition, the cleaning quality is unstable and is affected by the operator's experience and skill level, making it difficult to ensure consistency and reliability. At the same time, for large or complex fasteners, manual cleaning is difficult to handle effectively, which may affect product quality. Finally, these problems not only affect production efficiency and product quality, but may also increase production costs and burdens; Therefore, the present invention solves this problem by setting a certain structure. First, the placed fasteners are conveyed to the bottom of the two clamping assemblies by the conveyor belt, and then each fastener is clamped by starting the clamping assembly. After the fasteners are clamped, the fasteners are placed inside the cleaning frame 5. Then, when there are enough fasteners inside the cleaning frame 5, the sliding guide rail 510 is started to drive the cleaning frame 5 to move to the top of the positioning frame 7, and then the positioning frame 7 is started to slide upward. The upward movement of the positioning frame 7 will drive the positioning frame 7 to squeeze the cleaning agent stored in the liquid storage tank 72 to soak the cleaning frame 5, and then the positioning frame 7 will cover the entire cleaning frame 5, and the cleaning agent in the positioning frame 7 will flow into the cleaning frame 5, so as to clean the dirt and metal debris attached to the circumferential surface of the fasteners, thereby achieving the effect of automatic cleaning. The problem that operators need to come into contact with harmful cleaning agents sprayed on the surface of fasteners is solved, but this poses a threat to health, and long-term manual operation can easily lead to fatigue. Secondly, the cleaning efficiency is low, it is difficult to meet the needs of efficient and fast production, and the production cost is increased. In addition, the cleaning quality is unstable and is affected by the operator's experience and skill level, making it difficult to ensure consistency and reliability. At the same time, manual cleaning is difficult to handle effectively for large or complex fasteners, which may affect product quality.

[0025] like Figure 5 As shown, the clamping assembly of this embodiment includes a slider 62 slidably arranged on each second guide rail 61; and a first hydraulic cylinder 6 fixedly connected to the lower surface of each slider 62, two limit rings 63 are slidably arranged at the output end of each first hydraulic cylinder 6, and each limit ring 63 is controlled by an air pump; and a positioning rod 64 fixedly connected to the output end of the first hydraulic cylinder 6.

[0026] Specifically, by starting the two limit rings 63 controlled by the air pump to move toward each other, the two limit rings 63 will move toward the direction of the large fastener at the same time, thereby clamping the large fastener, and then the slider 62 moves along the second guide rail 61 to drive the second hydraulic cylinder 71 fixed to the lower surface of the slider 62 to move, and the second hydraulic cylinder 71 can drive the large fastener clamped at its output end to move toward the top of the cleaning frame 5. When it moves to the top of the cleaning frame 5, the first hydraulic cylinder 6 is started to place the large fastener at its output end into the cleaning frame 5, and then the two limit rings 63 release the clamping of the large fastener, and then this operation is repeated continuously, thereby achieving the effect of continuous feeding.

[0027] like Figure 6 As shown, in this embodiment, the cross-section of each limiting ring 63 is arc-shaped, and the material of each limiting ring 63 is rubber material, which is used to increase the friction between the large fasteners.

[0028] Specifically, by setting the material of each limiting ring 63 to rubber material, large fasteners can be better protected when clamping them, and the friction between the large fasteners and the limiting ring 63 can be increased, thereby making the clamping more stable and improving the clamping efficiency.

[0029] Example:

[0030] like Figures 2 to 10 As shown, compared with Example 1, another embodiment of the present invention is: a plurality of cleaning pieces are arranged in the cleaning frame 5, each of which can clean the circumferential surface of a large fastener; each cleaning piece includes a plurality of first motors 53 fixedly connected to the bottom wall of the cleaning frame 5, the output end of each first motor 53 is fixedly connected to a fixed disk 54, the upper surface of each fixed disk 54 is fixedly connected to a positioning ring 52, and the inner wall of each positioning ring 52 is fixedly connected to a plurality of brushes, and the brushes are used to clean the circumferential surface of the fastener; a fixed column 56 is fixedly connected to the upper surface of the fixed disk 54, and a connecting column 57 is slidably connected to the inside of the fixed column 56, a compression spring is elastically connected between the connecting column 57 and the fixed column 56, and the top of the connecting column 57 is rotatably connected to a chassis 58; two positioning holes 55 are provided on the surface of each fixed disk 54, and the positioning holes 55 are used to flow out the cleaned metal debris.

[0031] Specifically, after the large fastener is placed in the positioning ring 52 in the cleaning frame 5, the large fastener will abut against the chassis 58 inside the positioning ring 52. At this time, the large fastener will squeeze the chassis 58 under the action of its own gravity. , so that the connecting column 57 is locked in the fixing column 56, thereby fixing the large fastener on the basis, so that the large fastener can stand on the upper surface of the chassis 58, and then by starting a plurality of first motors 53 fixed to the bottom wall of the positioning frame 7, each first motor 53 drives the fixing disk 54 at its output end to rotate, and the rotation of the fixing disk 54 can drive the positioning ring 52 to rotate, and the rotation of the positioning ring 52 can clean the fastener, because the inner wall of the positioning ring 52 is fixed with a plurality of brushes, and at the same time, because the bottom plate rotation is arranged on the top of the connecting column 57, when the positioning ring 52 rotates relatively, the chassis 58 will not rotate at the same high speed as the positioning ring 52, so that the effect of automatic cleaning can be achieved, thereby cleaning the metal debris on the circumferential surface of the fastener, and then the surface of the fixing disk 54 is provided with a positioning hole 55, and these metal debris will flow out from the positioning hole 55, thereby improving the cleaning efficiency.

[0032] like Fig. 9 As shown, in this embodiment, a second hydraulic cylinder 71 is fixedly connected to the lower surface of the positioning frame 7, a third hydraulic cylinder 73 is fixedly connected to one side of the positioning frame 7, an output end of the third hydraulic cylinder 73 is fixedly connected to a push plate 74, and the push plate 74 is located inside the positioning frame 7, a fourth hydraulic cylinder 75 is fixedly connected to the other side of the positioning frame 7, and an output end of the fourth hydraulic cylinder 75 is fixedly connected to a sealing plate 76.

[0033] Specifically, by fixing the third hydraulic cylinder 73 on one side of the positioning frame 7, when a certain amount of metal debris is deposited in the positioning frame 7, it will affect the normal use of the positioning frame 7. These metal debris will react with the cleaning agent to a certain extent, thereby reducing the cleaning effect of the cleaning agent. Therefore, the third hydraulic cylinder 73 is started to drive the push plate 74 at its output end to scrape the metal sediment inside the positioning frame 7, and then when it is scraped above the sealing plate 76, the fourth hydraulic cylinder 75 is started to drive the sealing plate 76 to move, so that the metal sediment falls into the metal sedimentation frame inside the working box 1, thereby ensuring the cleaning effect of the cleaning agent and improving the cleaning quality of the cleaning agent.

[0034] like Figure 4As shown, the cleaning part of this embodiment includes a plurality of water spray pipes 42 fixedly connected to the inner wall of the working box 1, and the plurality of water spray pipes 42 are used to clean the cleaning agent attached to the circumferential surface of the fastener. A storage box 4 is fixedly connected to the upper surface of the top frame 2, and a sealing cover 41 is threadedly connected to the upper surface of the storage box 4; a guide platform 31 is fixedly connected to one side of the working box 1, and a first slot 35 is provided on the side of the working box 1 corresponding to the guide platform 31, and a first plug block 33 is inserted in the first slot 35, and a collecting frame 3 is fixedly connected to one side of the first plug block 33, and a collecting groove 32 is provided in the collecting frame 3, and a filter screen 34 is fixedly connected to the inside of the collecting frame 3.

[0035] Specifically, after cleaning by the cleaning frame 5, the positioning frame 7 is returned to the interior of the working box 1, and then the two sliding guide rails 510 are started again to drive the cleaning frame 5 to move to a location where there are several water spray pipes 42. By starting the pressure pump in the storage box 4, the water in the storage box 4 is sprayed out from the water spray pipes 42, thereby flushing the circumference of the fasteners after cleaning, so that the cleaning agent on the circumferential surface of the fasteners is flushed away. Because the cleaning agent is a rust remover, it is usually a strongly acidic or alkaline chemical reagent, and the residue may cause further corrosion to the bolts, thereby achieving the effect of protecting the fasteners.

[0036] Working principle: first, the placed fasteners are conveyed to the bottom of the two clamping assemblies by the conveyor belt, and then each fastener is clamped by starting the clamping assembly. By starting the two limit rings 63 controlled by the air pump to move toward each other, the two limit rings 63 will move toward the direction of the large fastener at the same time, thereby clamping the large fastener. Then, the slider 62 moves along the second guide rail 61, driving the second hydraulic cylinder 71 fixed to the lower surface of the slider 62 to move, and the second hydraulic cylinder 71 can drive the large fastener clamped at its output end to move toward the clear The first hydraulic cylinder 6 is moved above the cleaning frame 5. When it moves to the top of the cleaning frame 5, the first hydraulic cylinder 6 is started to place the large fastener at its output end into the cleaning frame 5, and then the two limit rings 63 release the clamping of the large fastener, and then this operation is repeated continuously, thereby achieving the effect of continuous feeding. In addition, by setting the material of each limit ring 63 to rubber material, the large fastener can be better protected when clamping the large fastener, and the friction between the large fastener and the limit ring 63 can be increased, so that the clamping is more stable and the clamping efficiency is improved; After the fasteners are clamped, the fasteners are placed inside the cleaning frame 5. Then, when there are enough fasteners inside the cleaning frame 5, the sliding guide rail 510 is started to drive the cleaning frame 5 to move to the top of the positioning frame 7. Then, the positioning frame 7 is started to slide upward. The upward movement of the positioning frame 7 will drive the positioning frame 7 to squeeze the cleaning agent stored in the liquid storage tank 72 to soak the cleaning frame 5. Then, the positioning frame 7 will cover the entire cleaning frame 5. The cleaning agent in the positioning frame 7 will flow into the cleaning frame 5, thereby cleaning the dirt and metal debris attached to the circumferential surface of the fasteners, thereby achieving an automatic cleaning effect. After the large fastener is placed in the positioning ring 52 in the cleaning frame 5, the large fastener will abut against the bottom plate 58 inside the positioning ring 52. At this time, the large fastener will squeeze the bottom plate 58 under the action of its own gravity. , so that the connecting column 57 is locked in the fixing column 56, so that the large fastener is basically fixed, so that the large fastener can stand on the upper surface of the chassis 58, and then by starting a plurality of first motors 53 fixed to the bottom wall of the positioning frame 7, each first motor 53 drives the fixing disk 54 at its output end to rotate, and the rotation of the fixing disk 54 can drive the positioning ring 52 to rotate, and the rotation of the positioning ring 52 can clean the fastener, because the inner wall of the positioning ring 52 is fixed with a plurality of brushes, and at the same time, because the bottom plate is rotatably arranged at the top of the connecting column 57, when the positioning ring 52 rotates relatively, the chassis 58 will not rotate at the same high speed as the positioning ring 52, so that the effect of automatic cleaning can be achieved, so that the metal debris on the circumferential surface of the fastener is cleaned down, and then the surface of the fixing disk 54 is provided with a positioning hole 55, and these metal debris will flow out from the positioning hole 55, thereby improving the cleaning efficiency; After cleaning by the cleaning frame 5, the positioning frame 7 is returned to the inside of the working box 1, and then the two sliding guide rails 510 are started again to drive the cleaning frame 5 to move to a plurality of water spray pipes 42, and the water in the storage box 4 is sprayed out from the water spray pipes 42 by starting the pressure pump in the storage box 4, so as to flush the circumference of the fasteners after cleaning, so that the cleaning agent on the circumferential surface of the fasteners is flushed away. Because the cleaning agent is a rust remover, it is usually a strongly acidic or alkaline chemical reagent, and the residue may cause further corrosion to the bolts, thereby achieving the effect of protecting the fasteners and completing the cleaning of the fasteners.
