Description

Technical Field

[0001] This invention relates to the field of polishing and grinding technology, and in particular to an automatic deburring device for workpieces. Background Technology

[0002] In fields such as machining, metal stamping, and precision parts manufacturing, after workpieces are processed and formed, defects such as burrs, flash, and oxide scale are commonly generated on their edges and surfaces. These defects not only affect the appearance quality of the product, but also reduce assembly accuracy and service life, and may even cause safety accidents. Therefore, deburring and surface polishing are indispensable steps in the workpiece processing.

[0003] In existing technologies, deburring operations are mostly carried out manually, where operators use tools such as files, sandpaper, and scrapers to trim workpieces one by one. However, manual operation is not only inefficient and difficult to meet the needs of mass production, but also the processing quality is highly dependent on the operator's experience and skill, resulting in poor consistency and problems such as workpiece surface damage or incomplete deburring. In addition, the labor intensity is high, and long-term operation can easily lead to personnel fatigue and pose safety hazards. Summary of the Invention

[0004] This application provides an automatic deburring device for workpieces, which automatically deburrs the workpieces, ensuring that the workpiece surface can be fully ground, and significantly improving the efficiency and quality of workpiece deburring.

[0005] This application provides an automatic deburring device for workpieces, which adopts the following technical solution: An automatic deburring device for workpieces includes a housing and a frame; the frame is disposed on the top surface of the housing, and the inner wall of the frame cooperates with the top surface of the housing to form a processing cavity; a disc is rotatably connected to two mutually distant inner walls of the processing cavity; a plurality of abrasive material bins are rotatably disposed between the two discs and evenly distributed along the circumference of the discs; a bin cover is installed at the top of each abrasive material bin; and a drive mechanism is provided on the frame to drive the abrasive material bins to revolve around the central axis and rotate on their own axis.

[0006] By adopting the above technical solution, when deburring the workpiece, the workpiece is placed in the grinding chamber by opening the hopper cover, abrasive is added into the grinding chamber, and the hopper cover is closed and locked. When the equipment is working, the grinding chamber is driven by the drive mechanism set on the frame to rotate with the disc while rotating on its own axis. This causes the workpiece and the abrasive to form a multi-dimensional and irregular relative motion in the grinding chamber, ensuring that all surfaces of the workpiece can be fully ground without any dead corners, thus improving the deburring quality.

[0007] Preferably, the drive mechanism includes a first motor; the first motor is mounted on the outer wall of the frame, and a rotating shaft extending horizontally into the processing cavity is coaxially fixed to the output end of the first motor; the rotating shaft passes horizontally through the two discs and is coaxially fixed to the two discs; a plurality of second motors are mounted on one end face of either of the two discs; the output ends of the plurality of second motors are respectively fixed to the end faces of a plurality of abrasive bins.

[0008] By adopting the above technical solution, the first motor and the second motor are started during the deburring process. The first motor drives the disc to rotate, causing the abrasive bin to revolve with the disc. The second motor drives the abrasive bin to rotate on its own axis. Through the cooperation of the first motor and the second motor, the workpiece and the abrasive are subjected to sufficient and irregular rolling and friction.

[0009] Preferably, a human-machine interface and a controller are provided on the outer wall of the frame; the input end of the controller is electrically connected to the human-machine interface, and the output end of the controller is electrically connected to the first motor and multiple second motors.

[0010] By adopting the above technical solution, the human-machine interface is used for operators to input operation commands, and the controller controls the speed and running time of the first motor and the second motor, realizing adjustable control of speed and time to adapt to the processing requirements of different workpieces.

[0011] Preferably, a sieve plate is horizontally arranged on the inner wall of the housing; a screen is arranged on the sieve plate; a discharge funnel located at the top of the screen is arranged on the top wall of the housing; the discharge funnel connects the processing chamber and the interior of the housing; an inclined guide plate located at the bottom of the screen is installed obliquely on the inner wall of the housing, and an abrasive inlet is opened on the inner wall of the housing corresponding to the lower end of the inclined guide plate; the abrasive inlet is connected to the top surface of the lower end of the inclined guide plate; a first guide plate located at the bottom of the abrasive inlet is arranged on the outer wall of the housing where the abrasive inlet is located.

[0012] By adopting the above technical solution, after the workpiece is ground, the hopper cover is opened and the mixture is poured into the discharge funnel. The screen screens the mixture for screening and filtering. The workpiece is blocked on the screen surface. Smaller abrasive particles fall through the mesh of the screen onto the inclined guide plate below. The inclined guide plate guides and conveys the abrasive particles, so that the abrasive particles are conveyed from the abrasive inlet to the first guide plate to complete the discharge and realize the recycling of abrasive particles.

[0013] Preferably, a stop block is fixedly connected to the inner wall of the housing; the end of the screen plate away from the stop block is hinged to the inner wall of the housing, and the end of the screen plate near the stop block rests on the top surface of the stop block; a discharge port is provided on the inner wall of the housing away from the stop block; the discharge port communicates with the top surface of the screen plate, and a door is provided on the inner wall of the discharge port; a second guide plate located at the bottom of the discharge port is provided on the outer wall of the housing where the door is located; an electric push rod located at the bottom of the stop block is hinged to the inner wall of the housing; the output end of the electric push rod is arranged obliquely upward, and the output end of the electric push rod is hinged to the bottom surface of the end of the screen plate near the stop block; the controller is electrically connected to the electric push rod.

[0014] By adopting the above technical solution, when the workpiece is discharged, the hopper door is opened first, the controller controls the electric push rod to extend, the screen plate drives the screen to swing upward, causing the workpiece on the screen to slide towards the discharge port side, and the workpiece is then transported to the second guide plate through the discharge port, realizing the automatic separation and transportation of the workpiece and the abrasive, without the need for manual sorting.

[0015] Preferably, a vibration motor is installed on the high-end bottom surface of the inclined guide plate.

[0016] By adopting the above technical solution, when the screened abrasive falls onto the inclined guide plate for conveying, the vibration motor is started to cause the inclined guide plate to vibrate, thereby reducing the possibility of wet abrasive adhering to the inclined guide plate and preventing abrasive agglomeration from causing blockage.

[0017] Preferably, a damper is vertically installed on the top surface of the screen plate at the position corresponding to the unloading funnel; a conical diverter plate is installed on the telescopic end of the damper.

[0018] By adopting the above technical solution, after the mixture is discharged from the discharge hopper and impacts the top surface of the conical diverter, the damper can absorb the impact energy without generating rebound oscillation. At the same time, the conical diverter can spread the mixture around along the conical surface, so that the mixture can fall evenly onto the screen for screening.

[0019] Preferably, a rubber pad is provided on the top surface of the conical diverter plate.

[0020] By adopting the above technical solution, the rubber pad can reduce the impact force of the mixture hitting the conical diverter plate and reduce the impact kinetic energy of the mixture on the filter screen during unloading and separation.

[0021] Preferably, a rotary motor is installed on the bottom surface of the sieve plate at the position corresponding to the damper; the output end of the rotary motor is fixedly connected to the bottom end of the damper; and a stirring plate is provided on the outer wall of the damper.

[0022] By adopting the above technical solution, when the grinding mixture is screened by the screen, the rotary motor is started to drive the damper to rotate, causing the stirring plate to rotate slowly and push the mixture on the top of the screen. This causes the mixture to roll and slide on the top of the screen to spread it out, so as to fully screen the mixture. This avoids the violent collision between the abrasive and the screen that is easily caused by high-frequency vibration screening, reduces secondary crushing of the abrasive during the separation process, and extends the service life of the abrasive.

[0023] Preferably, a laser ranging sensor is provided on the outer wall of the damper, located on the bottom surface of the conical splitter plate; the laser ranging sensor is electrically connected to the controller.

[0024] By adopting the above technical solution, the laser rangefinder can detect the displacement of the conical splitter plate in the buffer direction. When the displacement exceeds the preset threshold, the controller controls the second motor to drive the grinding hopper to swing and stop feeding to achieve overload protection.

[0025] In summary, this application has the following beneficial effects: 1. The workpiece and abrasive are put into the grinding bin. When the equipment is working, the grinding bin rotates on its own axis while revolving with the disc through the drive mechanism. This causes the workpiece and abrasive to form a multi-dimensional and irregular relative motion in the grinding bin, ensuring that all surfaces of the workpiece can be fully ground without any dead corners, and significantly improving the deburring and polishing quality. 2. The human-machine interface is set up for operators to input operation commands. The controller controls the speed and running time of the first motor and the second motor, realizing adjustable speed and time control to adapt to the processing requirements of different workpieces; 3. After grinding is complete, open the hopper cover and pour the mixture into the discharge funnel. The screen filters the mixture, and the workpiece is blocked on the screen surface. Smaller abrasive particles fall through the screen mesh onto the inclined guide plate below, and the abrasive is discharged from the abrasive outlet so that the first guide plate can guide and transport the abrasive. Open the hopper door so that the workpiece can be discharged from the discharge outlet so that the second guide plate can guide and transport the workpiece, thereby realizing the automatic separation and transportation of the workpiece and the abrasive, reducing the trouble of manual secondary sorting.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] This invention discloses an automatic deburring device for workpieces, such as... Figure 1 and Figure 2 As shown, it includes a housing 1, a frame 2, and a drive mechanism 5. The frame 2 is located on the top surface of the housing 1. The inner wall of the frame 2 and the top surface of the housing 1 cooperate to form a processing cavity with one side open. The processing cavity is rotatably connected to two coaxially arranged discs 3 on two mutually distant inner walls. The two discs 3 are connected by a horizontally arranged connecting rod. Multiple abrasive bins 4 are rotatably arranged on the two discs 3 on their mutually close side walls. The multiple abrasive bins 4 are evenly distributed around the circumference of the discs 3. Each abrasive bin 4 has a self-locking bin cover 41 hinged to its top surface. The drive mechanism 5 is set on the outer wall of the frame 2. The drive mechanism 5 includes a first motor 51 and a plurality of second motors 52. The first motor 51 is horizontally mounted on the outer wall of one end of the frame 2. The output end of the first motor 51 is coaxially fixed to a rotating shaft. The rotating shaft extends horizontally into the processing cavity and passes through two disks 3. The rotating shaft is coaxially fixed to the two disks 3. The plurality of second motors 52 are horizontally mounted on the outer end face of a disk 3. The output ends of the plurality of second motors 52 are coaxially fixed to the end faces of the plurality of abrasive bins 4 respectively.

[0030] The workpiece is placed in the grinding chamber 4, abrasive is added to the grinding chamber 4 and the chamber cover 41 is closed. When deburring, the first motor 51 and the second motor 52 are started. The first motor 51 drives the disc 3 to rotate and the second motor 52 drives the grinding chamber 4 to rotate. Through the cooperation of the first motor 51 and the second motor 52, the workpiece and the abrasive move randomly in the grinding chamber 4, and the workpiece is fully and evenly ground.

[0031] like Figure 1 and Figure 2 As shown, a human-machine interface 21 and a controller 22 are provided on the outer wall of the frame 2. The human-machine interface 21 is used to input operation commands and is electrically connected to the input terminal of the controller 22. The output terminal of the controller 22 is electrically connected to the first motor 51 and multiple second motors 52. The controller 22 controls the first motor 51 and the second motors 52 to work.

[0032] The human-machine interface 21 is used for operators to input operation commands, and the controller 22 controls the speed and running time of the first motor 51 and the second motor 52 to achieve adjustable speed and time control in order to adapt to the processing requirements of different workpieces.

[0033] like Figure 1 and Figure 3 As shown, a discharge funnel 11 is provided in the middle of the top wall of the machine housing 1. The discharge funnel 11 connects the processing chamber with the interior of the machine housing 1. A horizontally arranged screen plate 6 is provided on the inner wall of the machine housing 1 near the top. A screen mesh 61 is installed in the middle of the screen plate 6. An inclined guide plate 7 is fixed to the inner wall of the machine housing 1. The inclined guide plate 7 is arranged at an inclination and located at the bottom of the screen plate 6 and the screen mesh 61. An abrasive inlet 12 is provided on the inner wall of the machine housing 1 at the lower end of the inclined guide plate 7. The bottom wall of the abrasive inlet 12 is connected to the top surface of the lower end of the inclined guide plate 7. A first guide plate 13 located at the bottom of the abrasive inlet 12 is provided on the outer wall of the machine housing 1. A discharge port 15 connected to the top surface of the screen plate 6 is provided on the inner wall of one side of the machine housing 1. A self-locking door 16 is provided on the inner wall of the discharge port 15. A second guide plate 17 located at the bottom of the discharge port 15 is provided on the outer wall of the machine housing 1.

[0034] After the workpiece is ground, the hopper cover 41 is opened and the mixture is poured into the discharge funnel 11. The screen 61 filters the mixture, and the workpiece is blocked on the surface of the screen 61. Smaller abrasive particles fall through the mesh of the screen 61 onto the inclined guide plate 7 below. The abrasive particles are discharged from the abrasive outlet 12 and guided and conveyed by the first guide plate 13. After the hopper door 16 is opened, the workpiece can be discharged from the discharge outlet 15 and then guided and conveyed by the second guide plate 17.

[0035] like Figure 1 , Figure 3 and Figure 4As shown, a damper 63 is vertically installed at the center of the top surface of the screen plate 6, located at the bottom of the outlet end of the discharge hopper 11. A conical diverter plate 64 is installed at the top telescopic end of the damper 63. A rubber pad 641 is provided on the top surface of the conical diverter plate 64. A pair of laser rangefinders 67 located on the bottom surface of the conical diverter plate 64 are provided on the outer wall of the damper 63. The laser rangefinders 67 are electrically connected to the input end of the controller 22.

[0036] When the mixture is discharged from the discharge hopper 11, it will impact the conical diverter plate 64. The rubber pad 641 buffers the impact kinetic energy, and the damper 63 absorbs the impact energy, causing the mixture to spread evenly along the conical surface and fall onto the screen 61 for screening. The laser range sensor 67 can detect the displacement of the conical diverter plate 64 in the buffering direction. When the displacement exceeds the preset threshold, the controller 22 controls the feeding to stop to achieve overload protection.

[0037] like Figure 3 and Figure 4 As shown, a rotary motor 65 is vertically installed on the bottom surface of the sieve plate 6, corresponding to the position of the damper 63. The output end of the rotary motor 65 passes through the sieve plate 6 and is coaxially fixed to the bottom surface of the damper 63. A pair of stirring plates 66 are fixed to the outer wall of the damper 63.

[0038] When screening the mixture, the rotary motor 65 is started to drive the damper 63 to rotate, causing the stirring plate 66 to rotate slowly to move the mixture on the top of the screen 61, so that the mixture rolls and slides on the top of the screen 61 to spread it out, so as to fully screen the mixture.

[0039] like Figure 3 and Figure 5 As shown, multiple vibration motors 71 are installed on the bottom surface of the inclined guide plate 7 at the end away from the abrasive inlet 12.

[0040] When the abrasive falls onto the inclined guide plate 7, the vibration motor 71 is started to make the inclined guide plate 7 vibrate, reducing the possibility of wet abrasive adhering to the inclined guide plate 7 during the conveying process and preventing abrasive agglomeration from causing blockage.

[0041] like Figure 1 , Figure 3 and Figure 6 As shown, a stop block 14 located at the bottom of the screen plate 6 is fixed to the inner wall of the housing 1 on the side away from the discharge port 15. The end of the screen plate 6 near the discharge port 15 is hinged to the inner wall of the housing 1, and the end of the screen plate 6 away from the discharge port 15 rests on the top surface of the stop block 14. An electric push rod 62 arranged at an upward angle is provided on the inner wall of the housing 1 on the side where the stop block 14 is located. The bottom end of the electric push rod 62 is hinged to the inner wall of the housing 1, and the top end of the electric push rod 62 is hinged to the bottom surface of the screen plate 6. The output end of the controller 22 is electrically connected to the electric push rod 62, and the controller 22 controls the operation of the electric push rod 62.

[0042] When the workpiece is being picked up, the controller 22 controls the electric push rod 62 to extend, the screen plate 6 drives the screen 61 to swing upward, causing the workpiece to slide towards the discharge port 15 and be output through the discharge port 15 to achieve automatic discharge.

[0043] Working principle: The workpiece is placed in the grinding hopper 4, abrasive is added to the grinding hopper 4 and the hopper cover 41 is closed. During deburring, processing instructions are sent through the manual interface, and suitable grinding process parameters are set. The controller 22 controls the first motor 51 and the second motor 52 to work. The first motor 51 drives the disc 3 to rotate, and the second motor 52 drives the grinding hopper 4 to rotate. With the cooperation of the first motor 51 and the second motor 52, the workpiece and abrasive move randomly in the grinding hopper 4, and the workpiece is ground thoroughly and evenly. After grinding is completed, the hopper cover 41 is opened and the mixture is poured into the discharge funnel 11. After the mixture is discharged from the outlet of the discharge funnel 11, it will hit the conical diverter plate 64. The damper 63 can absorb the impact energy so that the conical diverter plate 64 does not rebound and vibrate. After the mixture hits the conical diverter plate 64, it will spread out along the conical surface and fall evenly onto the screen 61 for screening. When the mixture is screened by screen 61, the rotary motor 65 is started to drive the damper 63 and the stirring plate 66 to rotate. The stirring plate 66 agitates the mixture, causing it to tumble, slide, and spread out to achieve thorough screening. Larger workpieces are blocked on the top surface of screen 61, while smaller abrasive particles fall through the mesh of screen 61 onto the inclined guide plate 7 below. The inclined guide plate 7 guides and conveys the abrasive particles. As the abrasive particles slide down the inclined guide plate 7, the vibration motor is started. Machine 71 causes the inclined guide plate 7 to vibrate, preventing wet abrasive from adhering to the inclined guide plate 7, and prompting the abrasive to be conveyed from the abrasive port 12 to the first guide plate 13 to complete the discharge; when the workpiece is discharged, the hopper door 16 is opened, the controller 22 controls the electric push rod 62 to extend, the screen plate 6 drives the screen 61 to swing upward, the workpiece slides towards the discharge port 15 and is conveyed through the discharge port 15 to the second guide plate 17, thereby realizing the automatic separation and conveying of the workpiece and the abrasive without the need for manual sorting.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
