Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a nut cleaning device. Background Art

[0002] Nuts are a common fastener that is usually used with bolts or screws to fix parts or assemblies. The main function of a nut is to provide clamping force by engaging with a threaded rod, thereby achieving a tight fixation between connected parts. Nuts usually have a round or hexagonal shape and have a threaded hole on the inside that matches the bolt or screw.

[0003] When processing nuts, it is necessary to select suitable raw materials, and then cut the raw materials into a length suitable for processing, and then turn and roll the nuts. After rolling, the nuts that have been tapped will be surface treated, that is, galvanized, chrome-plated, etc. However, the nuts after turning and tapping will be stained with turning oil and metal chips, and the attached turning oil and metal chips will seriously affect the effect of the surface treatment. Therefore, in order to ensure the quality of the surface treatment, the nuts after tapping need to be cleaned to remove the turning oil and metal chips. The current nut cleaning method is mainly to achieve the cleaning purpose through ultrasonic cleaning, but fine metal chips will be embedded in the gap of the internal thread of the nut. Therefore, when using ultrasonic cleaning, the ultrasonic wave may cause the part of the metal chips to be unable to be removed, which will affect the next step of surface treatment. Therefore, in order to increase the cleaning effect of the internal thread of the nut, a nut cleaning device for cleaning the internal thread is urgently needed. Summary of the invention

[0004] The present invention aims to provide a nut cleaning device to solve the problem that metal chips in the internal threads of the existing nut are difficult to clean.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a nut cleaning device, comprising a cleaning cylinder, a slag removal mechanism and a material guide plate, wherein a feeding port is provided at the top of the cleaning cylinder, a motor is fixedly connected to the outer bottom of the cleaning cylinder, the output shaft of the motor passes through the cleaning cylinder upward and is located in the cleaning cylinder, a rotating disk is provided in the cleaning cylinder, the center of the lower surface of the rotating disk is fixedly connected to the output shaft of the motor, a plurality of filter holes are evenly distributed on the rotating disk, and the filter holes are used for metal chips to pass through, the rotating disk drives the water in the cylinder to rotate and flow when rotating, and at the same time drives the nut to move up and down in the cylinder when the rotating disk rotates;

[0006] The slag removal mechanism comprises a vertical rod and two groups of fixing components, the vertical rod is arranged in the cleaning cylinder and is located directly below the feed port, the top end of the vertical rod is designed as a pointed end, the rod diameter of the vertical rod is smaller than the aperture diameter of the threaded hole of the nut, and a thread gauge matching the threaded hole of the nut is provided in the middle of the vertical rod; the two groups of fixing components are fixed in parallel on the inner wall of the cleaning cylinder, and the two groups of fixing components are used to clamp and fix the vertical rod so that the vertical rod is vertically fixed in the cleaning cylinder; each group of fixing components comprises two cylinders, the two cylinders are transversely fixedly connected to the inner wall of the cleaning cylinder, and the output shafts of the two cylinders are directly opposite to each other, and the top ends of the output shafts of the cylinders are fixedly connected with a clamping block, and the clamping blocks on the two cylinders are used to cooperate with each other to clamp the vertical rod; a transverse support rod is fixedly connected to the inner wall of the cleaning cylinder, and one end of the support rod away from the inner wall of the cleaning cylinder is fixedly connected to a rotating motor with an output shaft in a vertical state, and a connecting rod is fixedly connected to the output shaft of the rotating motor, and the connecting rod is used to drive the nut on the vertical rod to rotate and move from the top end of the thread gauge to the bottom end;

[0007] The material guide plate is tilted and fixed on the top of the cleaning cylinder, and the bottom end of the material guide plate is located at the material feed port.

[0008] The working principle of the present invention is as follows: before use, the cleaning cylinder is filled with cleaning liquid, and the liquid level of the cleaning liquid is not higher than the bottom end of the vertical rod. When cleaning the nut, a group of fixed components located below clamps the bottom of the vertical rod through the clamping block to keep the vertical rod in a vertical state. At this time, the nut to be cleaned is placed flat on the inclined guide plate. At this time, the nut slides horizontally along the guide plate to the feed port under the action of gravity. The top of the vertical rod is designed as a pointed end. Therefore, when the nut slides horizontally to the feed port, the nut will fall downward and then penetrate into the vertical rod until it falls to the thread gauge and is blocked by the thread gauge and stops falling. At this time, the rotating motor runs and then drives the connecting rod to rotate through the output shaft. When the connecting rod rotates, the nut on the vertical rod is pushed to rotate by friction. When the nut rotates, it moves from the top of the thread gauge to the bottom of the thread gauge. During the movement of the nut, the thread rule pushes out the metal chips in the internal thread gap of the nut. At this time, the metal chips in the internal thread of the nut are cleaned. After the nut moves to the bottom of the thread gauge, the nut is no longer blocked by the thread gauge and falls along the vertical rod to the bottom of the vertical rod. After the internal threads of a batch of nuts are cleaned, the clamping blocks of the upper fixing assembly are controlled to approach each other to clamp and fix the top of the vertical rod, and the nut falling from the top of the vertical rod is blocked by the clamping blocks and cannot continue to fall down. At this time, the clamping blocks of the lower fixing assembly are controlled to move away from each other to release the clamping of the bottom of the vertical rod. At this time, the nut falls into the cleaning cylinder under the action of gravity, and the surface of the rotating disk is rotated. After the nut falls, the two clamping blocks of the lower fixing assembly are controlled to approach again to clamp and fix the bottom of the vertical rod, and then the upper fixing assembly is controlled to release the fixation of the top of the vertical rod. At this time, the nut continues to fall and penetrates into the vertical rod. Repeat this process to clean the metal chips in the internal threads of all nuts.

[0009] At this time, start the motor. When the motor is running, it drives the rotating disk to rotate. When the rotating disk rotates, it drives the cleaning fluid in the cleaning cylinder to flow horizontally to form a vortex. When the cleaning fluid flows, the friction between the nut and the nut washes away the turning oil and metal chips attached to the nut. The washed away metal chips sink in the cleaning fluid and pass through the filter holes on the rotating disk. At the same time, when the rotating disk rotates, it drives the nut to move upward in the cleaning fluid, and then the nut falls back onto the rotating disk under the action of gravity. This is repeated to enhance the effect of cleaning away the metal chips attached to the surface of the nut.

[0010] Beneficial effects of the present invention:

[0011] 1. This solution can effectively clean the metal chips in the internal threads of the nut. At the same time, the rotation of the rotating disk drives the flow of the cleaning liquid, and the surface turning oil and metal chips attached to the surface of the nut after the metal chips in the internal threads are cleaned are cleaned, which can effectively ensure the cleanliness of the nut.

[0012] 2. When cleaning the nuts, just pour the nuts onto the guide plate and keep them lying horizontally. This makes the operation and cleaning easy and improves the efficiency of nut cleaning.

[0013] 3. The nut is driven to move upward in the cleaning liquid by the rotating disk, and then falls in the cleaning liquid under the action of its own gravity, so that the nut can move up and down in the cleaning liquid. First, it can increase the disturbance of the water flow, which helps the cleaning liquid to better penetrate every corner of the nut surface. Second, when the nut moves up and down, the impact of the water flow helps to loosen and remove the turning oil and metal chips attached to the surface of the nut. Third, it can accelerate the process of dirt shedding, thereby shortening the time required for the entire cleaning and improving the cleaning efficiency.

[0014] Furthermore, the circumference of the rotating disk is in clearance with the inner wall of the cleaning cylinder, and two arc-shaped protrusions are integrally formed on the upper surface of the rotating disk. The purpose is that when the rotating disk rotates, the nut can move along the surface of the arc-shaped protrusions to the highest point of the protrusions, and then fall down under the action of gravity, thereby realizing the up and down movement of the nut in the cleaning liquid when the rotating disk rotates.

[0015] Furthermore, the upper and lower parts of the vertical rod are provided with a clamping groove used in conjunction with the clamping block, and the clamping groove is rectangular. The purpose is to use a rectangular clamping groove, and insert the clamping block into the clamping groove, so as to avoid the vertical rod from rotating synchronously due to the influence of friction when the connecting rod rotates to drive the nut to rotate.

[0016] Furthermore, a controller is fixedly connected to the outer wall of the cleaning cylinder, and the rotating motor, the motor and the cylinders of the two fixed components are respectively connected to the controller by electrical signals. The purpose is to automatically control the motor, the rotating motor and the cylinders of the two fixed components by programming the controller to achieve automatic cleaning of the nut.

[0017] Furthermore, the top of the guide plate is fixedly connected with a feed hopper, the bottom of the feed hopper is inclined, and the discharge port of the feed hopper is located at the lowest point of the bottom of the feed hopper, and the height of the discharge port of the feed hopper is greater than the thickness of the nut but less than the height of the nut when it is erected. The purpose is that through this arrangement, when the nut is put into the feed hopper, the nut slides down along the inclined bottom of the feed hopper under the action of gravity, and then the nut can only slide out of the discharge port in a flat state, ensuring that the nut is in a flat state when it slides from the feed hopper to the guide plate.

[0018] Furthermore, a vibrator is fixedly mounted on the outer wall of the feed hopper, so as to push the nut to slide downward along the inclined surface of the bottom of the feed hopper through the vibration generated when the vibrator is running. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The slag removal mechanism includes a vertical rod 7 and two groups of fixed components. The vertical rod 7 is arranged in the cleaning cylinder 4 and is located directly below the feed port 17. The top of the vertical rod 7 is designed as a tip. The rod diameter of the vertical rod 7 is smaller than the diameter of the threaded hole of the nut. A thread gauge 8 matching the threaded hole of the nut is provided in the middle of the vertical rod 7. The upper and lower parts of the vertical rod 7 are provided with a clamping groove used in conjunction with the clamping block, and the clamping groove is rectangular. The two groups of fixed components are fixed on the inner wall of the cleaning cylinder 4 in parallel. The two groups of fixed components are used to clamp and fix the vertical rod 7 so that the vertical rod 7 is vertically fixed in the cleaning cylinder 4. Each group of fixed components includes two cylinders 5. The two cylinders 5 are fixedly connected to the inner wall of the cleaning cylinder 4 horizontally, and the output shafts of the two cylinders 5 are opposite to each other. The top of the output shaft of the cylinder 5 is fixedly connected with a clamping block. The clamping block of the upper group of fixed components is connected to the first wedge-shaped clamping block 6, and the tip of the first clamping block 6 contacts the vertical rod 7. The clamping block of a set of fixed components located at the bottom is a second clamping block 10 in the shape of a rectangular column; a horizontal support rod 14 is fixedly connected to the inner wall of the cleaning cylinder 4, and a rotating motor 16 with a vertical output shaft is fixedly connected to one end of the support rod 14 away from the inner wall of the cleaning cylinder 4, and a connecting rod 15 is fixedly connected to the output shaft of the rotating motor 16, and the connecting rod 15 is used to drive the nut on the vertical rod 7 to rotate and move from the top end of the thread gauge 8 to the bottom end;

[0025] The guide plate 18 is fixed obliquely on the top of the cleaning cylinder 4, the bottom end of the guide plate 18 is located at the feed port 17, the top of the guide plate 18 is fixedly connected to the feed hopper 1, the outer wall of the feed hopper 1 is fixedly mounted with a vibrator 2, the bottom 3 of the feed hopper is inclined, and the discharge port 9 of the feed hopper 1 is located at the lowest point of the bottom of the feed hopper 1, and the height of the discharge port 9 of the feed hopper 1 is greater than the thickness of the nut but less than the height of the nut when it is erected. A controller is fixedly connected to the outer wall of the cleaning cylinder 4, and the rotating motor 16, the motor 13 and the cylinders 5 of the two fixed components are respectively connected to the controller by electrical signals.

[0026] The specific implementation process is as follows:

[0027] Before use, the cleaning cylinder 4 is filled with cleaning liquid, and the liquid level of the cleaning liquid is not higher than the bottom end of the vertical rod 7. When cleaning the nut, a group of fixing components located below clamps the bottom of the vertical rod 7 through the second clamping block 10 to keep the vertical rod 7 in a vertical state. At this time, the nut to be cleaned is placed flat on the inclined guide plate 18. At this time, the nut slides horizontally along the guide plate 18 to the feed port 17 under the action of gravity. The top of the vertical rod 7 is designed as a pointed end. Therefore, when the nut slides horizontally into the feed port 17, the nut will fall downward and then penetrate into the vertical rod 7 until it falls to the thread gauge 8 and is blocked by the thread gauge 8 and stops falling. At this time, the rotating motor 16 runs and drives the connecting rod 15 to rotate through the output shaft. When the connecting rod 15 rotates, the nut on the vertical rod 7 is pushed to rotate by friction. When the nut rotates, it moves from the top of the thread gauge 8 to the bottom of the thread gauge 8. During the movement of the nut, the thread gauge 8 pushes out the metal chips in the internal thread gap of the nut. At this time, the metal chips in the internal thread of the nut are cleaned. After the nut moves to the bottom of the thread gauge 8, the nut is no longer blocked by the thread gauge 8, and then falls along the vertical rod 7 to the bottom of the vertical rod 7. After the internal threads of a batch of nuts are cleaned, the first clamping blocks 6 of the upper fixing assembly are controlled to approach each other to clamp and fix the top of the vertical rod 7, and the nut falling from the top of the vertical rod 7 is blocked by the second clamping block 10 so that it cannot continue to fall downward. At this time, the second clamping blocks 10 of the lower fixing assembly are controlled to move away from each other to release the clamping of the bottom of the vertical rod 7. At this time, the nut falls into the cleaning cylinder 4 under the action of gravity, and the surface of the rotating disk 12 is rotated. After the nut falls, the two second clamping blocks 10 of the lower fixing assembly are controlled to approach again to clamp and fix the bottom of the vertical rod 7, and then the upper fixing assembly is controlled to release the fixation of the top of the vertical rod 7. At this time, the nut continues to fall and penetrate into the vertical rod 7. This is repeated to clean the metal chips in the internal threads of all nuts.

[0028] At this time, the motor 13 is started. When the motor 13 is running, it drives the rotating disk 12 to rotate. When the rotating disk 12 rotates, it drives the cleaning liquid in the cleaning cylinder 4 to flow horizontally to form a vortex. When the cleaning liquid flows, the friction between the cleaning liquid and the nut washes away the turning oil and metal chips attached to the nut. The washed away metal chips sink in the cleaning liquid and pass through the filter holes on the rotating disk 12. At the same time, when the rotating disk 12 rotates, it drives the nut to move upward in the cleaning liquid, and then the nut falls back onto the rotating disk 12 under the action of gravity. This is repeated to enhance the effect of cleaning away the metal chips attached to the surface of the nut.
