Description

Technical Field

[0001] This invention relates to the field of parts grinding, and particularly to a grinding device for electrical components. Background Technology

[0002] In the fields of electrical equipment manufacturing and mechanical assembly, metal pipes are widely used basic components, often for line protection, fluid transportation, or structural support. To ensure the smoothness of the pipe's inner wall and remove machining burrs and welding residues, the inner wall of the pipe needs to be ground.

[0003] Currently, devices for grinding the inner walls of pipes are often equipped with dust collection functions to improve the working environment and meet environmental protection requirements. Existing technologies mostly adopt the following method: the pipe is placed horizontally, the grinding head is inserted into its interior to work, and a high-power negative pressure vacuum cleaner installed on the device captures the dust as it flies and sucks it into a dust bag or dust box.

[0004] However, this method generates a large amount of metal dust that accumulates on the bottom of the pipe's inner wall and on the worktable supporting the workpiece. Even with vacuuming equipment, a significant amount of fine dust remains. After grinding, operators need to spend extra time cleaning the worktable and the inside of the pipe. This process is not only inefficient and prone to causing secondary dust pollution, but it also increases the workload of operators and affects the continuity of production. Especially when grinding the inner walls of metal pipes in batches, it is essential to ensure the worktable is clean before each placement of the pipe; otherwise, residual dust will affect the stability of the pipe placement and may even scratch the surface of the workpiece. Summary of the Invention

[0005] This invention provides an electrical component grinding device that can solve the problem of frequent cleaning of the workbench due to dust pollution during pipe grinding in the prior art.

[0006] An electrical component grinding device, comprising:

[0007] The support assembly includes a frame and a mounting bracket mounted on the frame. A dust collection assembly is mounted on the support assembly, and the dust collection assembly has a dust inlet for collecting dust after grinding.

[0008] A support mechanism is installed on the mounting frame and has multiple support parts. The pipe is placed on the multiple support parts, and the dust collection assembly is located below the multiple support parts. The support mechanism drives the multiple support parts to shake and move so that the bottom end of the pipe is completely exposed below the dust inlet.

[0009] The support section vibrates to shake off the dust on its surface into the dust inlet;

[0010] The grinding mechanism includes an electric telescopic rod mounted on the frame, the telescopic end of the electric telescopic rod facing downward and rotatably mounted with a connecting shaft, a driving component for driving the connecting shaft to rotate is mounted on the frame, and a grinding component capable of adapting to different pipe inner walls is mounted at the bottom of the connecting shaft.

[0011] Furthermore, the support mechanism includes a support plate rotatably mounted on the mounting frame via a circular array of shafts. Both ends of the shafts are equipped with connecting discs, and one end of each connecting disc has an eccentrically constructed column. A forcing rod is rotatably mounted on the mounting frame, and the forcing rod has a movable groove. The column slides tangentially within the movable groove. A pull-out component is slidably mounted on the mounting frame. When the pull-out component moves, it drives the forcing rod to rotate continuously in a reciprocating shaking state.

[0012] Furthermore, the pull-out member includes a sliding block slidably mounted on the mounting bracket, a driving plate slidably mounted on the sliding block, a connecting rod hinged between the driving plate and the forcing rod, a transmission member for driving multiple sliding blocks to move is mounted on the mounting bracket, and a linkage component acting on the driving plate is mounted on the sliding block. When the sliding block moves, the driving plate is driven to reciprocate through the linkage component.

[0013] Furthermore, the linkage assembly includes a rotating disk rotatably mounted on the drive plate, a drive rod eccentrically mounted at the top of the rotating disk, a sliding groove provided on the drive plate, the drive rod sliding tangentially within the sliding groove, a drive rack mounted on the mounting bracket, and a drive gear meshing with the drive rack mounted on the rotating disk.

[0014] Furthermore, the transmission component includes a connecting cylinder mounted in a circular array on the mounting bracket. A connecting rod is slidably inserted into one end of the connecting cylinder, and the free ends of multiple connecting rods are respectively connected to multiple sliding blocks. An air pipe is connected to one side of the connecting cylinder, and an air inlet assembly is connected to the air pipe. A return spring is installed between the connecting rod and the connecting cylinder.

[0015] Furthermore, the mounting frame has multiple air inlets mounted in a circular array. A piston rod is slidably inserted into one end of each air inlet, and a positioning plate for contacting the outer periphery of the pipe is installed on the free end of the piston rod. The air inlet assembly is used to apply and release air pressure into and into the air inlet and connecting cylinder.

[0016] Furthermore, the dust collection assembly includes a drawer-type outer box mounted on the frame, with a dust inlet pipe vertically connected to the top of the drawer-type outer box and located below the mounting frame. A drawer-type inner box is slidably disposed inside the drawer-type outer box, and a compression assembly for compressing dust is installed in the drawer-type inner box.

[0017] Furthermore, two partitions are symmetrically installed on the drawer-type inner box, which divide the drawer-type inner box cavity into two sliding cavities and a dust cavity. The bottom surface of the dust cavity is evenly provided with air holes and a dust filter cloth. Sliding plates are slidably installed in both sliding cavities, and a limit baffle is installed between the two sliding plates. An extrusion plate located in the dust cavity is installed between the sliding plates.

[0018] Furthermore, the extrusion plate is rotatably installed between two sliding plates. One of the partitions has a receiving groove on the side facing the dust chamber. A forcing strip is elastically slidably inserted in the receiving groove. One end of the forcing strip has a forcing inclined surface. When the extrusion plate contacts the forcing inclined surface, the limiting baffle restricts the rotation of the extrusion plate and drives the forcing strip to move into the receiving groove.

[0019] Furthermore, the grinding assembly includes a drive cylinder slidably mounted on the connecting shaft. Multiple movable plates are slidably mounted in a circular array on the drive cylinder. A grinding brush is mounted on the side of the movable plate away from the axis of the connecting shaft. Two hinged rods distributed vertically are hinged to the side of the movable plate near the axis of the connecting shaft. The free ends of the two hinged rods are hinged to the connecting shaft. An adjusting cylinder is threaded onto the connecting shaft. The adjusting cylinder is rotatably mounted on the drive cylinder.

[0020] Beneficial effects:

[0021] This invention uses a support mechanism to move the support part out of the dust inlet. During the movement, the support part continuously shakes to shake off the dust on its surface into the dust inlet. Afterward, the support part moves to directly above the dust inlet, making it convenient to place the next pipe to be ground, thus ensuring the continuity of the production rhythm. This improves the overall grinding efficiency during batch grinding, avoids the dust remaining on the support part from affecting the placement of subsequent pipe workpieces, and reduces the need to clean the workbench.

Detailed Implementation

[0036] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0037] like Figures 1 to 12 As shown, an embodiment of the present invention provides an electrical component grinding device, comprising:

[0038] The support component 1 includes a frame 101 and a mounting bracket 102 mounted on the frame 101. A dust collection component 103 is mounted on the support component 1. The dust collection component 103 has a dust inlet for collecting dust after grinding. That is, after the pipe is ground, the dust directly enters the dust collection component 103 from the dust inlet, thereby completing the collection of dust.

[0039] The support mechanism 2 is installed on the mounting bracket 102 and has multiple support parts. The pipe is placed upright on the multiple support parts. The dust collection assembly 103 is located below the multiple support parts. The support mechanism 2 drives the multiple support parts to shake and move, so that the bottom end of the pipe is completely exposed below the dust inlet. The support parts shake to shake off the dust on their surface into the dust inlet. That is to say, when in use, the pipe is placed on the multiple support parts and then polished. After the pipe is polished, some of the dust will directly enter the dust collection assembly 103 through the dust inlet, while some of the dust on the support parts will be moved by the support mechanism 2. During the movement, the support parts will continue to shake to shake off the dust on their surface into the dust inlet. Then the support parts will move to the top of the dust inlet, which is convenient for the next pipe to be polished. This ensures the continuity of the production rhythm, improves the overall polishing efficiency during batch polishing, avoids the dust remaining on the support parts from affecting the placement of subsequent pipe workpieces, and reduces the cleaning of the workbench.

[0040] The grinding mechanism 3 includes an electric telescopic rod mounted on the frame 101. The telescopic end of the electric telescopic rod faces downward and is rotatably mounted with a connecting shaft 301. A driving component 302 for driving the connecting shaft 301 to rotate is mounted on the frame 101. A grinding assembly 303 adaptable to different pipe inner walls is mounted at the bottom of the connecting shaft 301. In this embodiment, the grinding mechanism 3 is not specifically limited and can be any structure that can meet the grinding requirements of this application. Preferably, such as... Figure 5 and Figure 6As shown, the grinding assembly 303 includes a drive cylinder 3033 slidably mounted on the connecting shaft 301. Multiple movable plates 3031 are slidably mounted in a circular array on the drive cylinder 3033. A grinding brush 3032 is mounted on the side of each movable plate 3031 away from the axis of the connecting shaft 301. Two hinged rods 3035, arranged vertically, are hinged to the side of each movable plate 3031 closest to the axis of the connecting shaft 301. The free ends of the two hinged rods 3035 are hinged to the connecting shaft 301. An adjusting cylinder 3034 is threaded onto the connecting shaft 301. The adjusting cylinder 3034 is rotatably mounted on the driving cylinder 3033. The driving component 302 includes a motor mounted on the frame 101. The motor is a shaftless motor and has a rotating ring installed inside. A protruding plate is constructed on the inner circumference of the rotating ring. A limiting groove is formed on the outer circumference of the connecting shaft 301. The rotating ring is sleeved on the connecting shaft 301, and the protruding plate is located in the limiting groove. This does not affect the vertical movement of the connecting shaft 301 driven by the electric telescopic rod, and the motor drives the rotating ring to rotate. When in motion, it can also drive the connecting shaft 301 to rotate. During grinding, first, the adjusting cylinder 3034 is rotated according to the inner diameter of the pipe. At this time, the adjusting cylinder 3034 moves spirally. Because the driving cylinder 3033 is slidably mounted on the connecting shaft 301 and is slidably engaged with the adjusting cylinder 3034, when the adjusting cylinder 3034 moves spirally, it will drive the driving cylinder 3033 to move vertically. When the driving cylinder 3033 moves on the connecting shaft 301, it will force the moving plate 3031, which is horizontally slidably mounted on it, to move vertically. However, at this time, because of the movement... A hinge rod 3035 is hinged between plate 3031 and connecting shaft 301. Therefore, when the drive cylinder 3033 moves downward, it will force the moving plate 3031 to move downward in an arc. Since there are two hinge rods 3035, which form a parallelogram hinge with the connecting shaft 301, the moving plate 3031 will eventually move downward in a vertical arc. This ensures that the grinding brush 3032 on the moving plate 3031 can fully contact the inner wall of the pipe, enabling grinding of pipes with different inner diameters and ensuring the grinding effect.

[0041] like Figure 4 , Figures 10 to 12As shown, the support mechanism 2 includes a support plate 202 rotatably mounted on the mounting frame 102 via a circular array of shafts 201. In this embodiment, the support part refers to the support plate 202, which is a rectangular thin plate. Connecting discs 203 are mounted at both ends of the shafts 201. A column rod 204 is eccentrically mounted at one end of each connecting disc 203. A forcing rod 205 is rotatably mounted on the mounting frame 102. A movable groove 206 is formed on the forcing rod 205, and the column rod 204 slides tangentially within the movable groove 206. A pull-out member 207 is slidably mounted on the mounting frame 102. When the pull-out member 207 moves, it drives the forcing rod 205 to rotate continuously in a reciprocating shaking state. In other words, during grinding, the multiple support plates 202 are in a horizontal state. When the support plates 202 need to rotate, the pull member 207 moves. When the pull member 207 moves, it drives the forced rod 205 to rotate. The forced rod 205 rotates continuously downward in a shaking state. In this way, through the sliding cooperation between the column rod 204 and the movable groove 206, the connecting plate 203 can be continuously rotated in one direction in a small-amplitude reciprocating manner. This causes the support plates 202 to shake continuously during rotation, thereby shaking the dust on the surface of the support plates 202 into the dust inlet until the support plates 202 no longer affect the natural falling of dust inside the pipe. This not only cleans the dust on the surface of the support plates 202, but also does not affect the discharge of dust inside the pipe.

[0042] like Figure 10 and Figure 12As shown, in some embodiments, the pull member 207 includes a sliding block 2071 slidably mounted on the mounting bracket 102. A driving plate 2072 is slidably mounted on the sliding block 2071. A connecting rod 2073 is hinged between the driving plate 2072 and the forcing rod 205. A transmission member 208 for driving the movement of multiple sliding blocks 2071 is mounted on the mounting bracket 102. A linkage component 209 acting on the driving plate 2072 is mounted on the sliding block 2071. When the sliding block 2071 moves, the driving plate 2072 is driven to reciprocate through the linkage component 209. That is, the movement of multiple sliding blocks 2071 can be realized through the transmission member 208. Multiple sliding blocks 2071 move to move multiple driving plates 2072. Since the driving plates 2072 are hinged to the forcing rod 205 via the linkage 2073, the forcing rod 205 will rotate continuously. As the linkage component 209 moves the sliding blocks 2071, the driving plates 2072 reciprocate. Therefore, during the continuous movement of the sliding blocks 2071, the driving plates 2072 move rapidly back and forth on the sliding blocks 2071, thereby causing the forcing rod 205 to vibrate back and forth during continuous rotation. The vibration of the driving plates 2072 is automatically achieved when the sliding blocks 2071 move, making it more convenient to use and eliminating the need for additional control to start the vibration of the forcing rod 205.

[0043] like Figures 9 to 12The specific structure of the linkage component 209 is disclosed. The linkage component 209 includes a rotating disk 2091 rotatably mounted on the drive plate 2072. A drive rod 2092 is eccentrically mounted at the top of the rotating disk 2091. A sliding groove 2093 is provided on the drive plate 2072, and the drive rod 2092 slides tangentially within the sliding groove 2093. A drive rack 2094 is mounted on the mounting bracket 102, and a drive gear 2095 meshing with the drive rack 2094 is mounted on the rotating disk 2091. That is, when the sliding block 2071 moves continuously, because the drive gear 2095 is mounted on the sliding block 2071 through the rotating disk 2091 and meshes with the drive rack 2094, the sliding block 2071 moves through the drive gear. The drive gear 2095 enables the rotation of the rotating disk 2091. It should be noted that the smaller the tooth diameter and the fewer the teeth of the drive gear 2095, the faster the rotation speed of the rotating disk 2091 will be during the continuous movement of the sliding block 2071. This will make the reciprocating vibration of the forced rod 205 faster, thereby improving the vibration effect of the support plate 202. When the rotating disk 2091 rotates continuously, it will drive the drive rod 2092 to rotate continuously. Because the drive rod 2092 slides tangentially within the slide groove 2093, when the drive rod 2092 rotates eccentrically around the rotating disk 2091, it will force the drive plate 2072 to move back and forth, thus realizing the reciprocating vibration of the drive plate 2072. It should be noted that the closer the drive rod 2092 is to the center of the rotating disk 2091, the smaller the reciprocating vibration amplitude of the drive plate 2072.

[0044] In this application, the drive rack 2094, in conjunction with the drive gear 2095, enables the continuous rotation of the rotating disk 2091. The drive rod 2092 then forces the rod 205 to vibrate. Vibration can be automatically achieved simply by controlling the movement of the sliding block 2071, which is convenient to use. Furthermore, the pressure exerted on the pipe by the grinding brush 3032 during its downward movement is relatively small, which is sufficient to meet the bearing requirements during pipe grinding. Of course, a small motor could also be installed on the sliding block 2071 to control the rotation of the rotating disk 2091 to achieve the purpose of vibration. However, in this embodiment, there are six support plates 202 arranged in a circular pattern, which ensures that the bottom surface of the pipe is subjected to uniform force. Using six small motors would require additional sensors and additional programming to control the drive of the small motors during operation, which is not only inconvenient to use but also requires more energy.

[0045] like Figures 10 to 12As shown, in some embodiments, the transmission component 208 includes a circular array of connecting cylinders 2081 mounted on the mounting bracket 102. A connecting rod 2082 is slidably inserted into one end of each connecting cylinder 2081. The free ends of multiple connecting rods 2082 are respectively connected to multiple sliding blocks 2071. An air pipe 2083 is connected to one side of the connecting cylinder 2081. The air pipe 2083 is connected to an air intake assembly 2084. A return spring 2085 is installed between the connecting rods 2082 and the connecting cylinder 2081. In other words, gas is supplied to the air pipe 2083 through the air intake assembly 2084. In this embodiment, the air intake assembly 2084 can be an air pump, thereby increasing the air pressure inside the connecting cylinder 2081 to push the connecting rod 2082 to move. When the connecting rod 2082 moves, it will drive the sliding block 2071 to move. At this time, the return spring 2085 will be stretched. When the support plate 202 remains horizontal, the air pressure inside the connecting cylinder 2081 remains constant. When the connecting rod 2082 moves to its maximum limit position, the return spring 2085 is stretched. Spring 2085 is in a stretched state. When the air pump is turned off, the air pressure inside the connecting cylinder 2081 is released, thereby causing the connecting rod 2082 to move and reset through the return spring 2085, thus realizing the rotation of multiple support plates 202. During the grinding process, in order to prevent the pipe from shaking and the pipe from falling into the dust collection assembly 103 after the support plates 202 rotate, the worker can hold the pipe by hand or use a clamp to fix the pipe. Preferably, in this embodiment, multiple air inlets 4 are installed in a circular array on the mounting frame 102. A piston rod 5 is slidably inserted into one end of the air inlet 4. Preferably, a spring is installed between the air inlet 4 and the piston rod 5. A positioning plate 6 for contacting the outer periphery of the pipe is installed on the free end of the piston rod 5. The air intake assembly 2084 is used to apply and release air pressure to the air inlet 4 and the connecting cylinder 2081. Specifically, since this device is generally installed in a factory, the factory generally has a built-in high-pressure air pipe 2083, which can directly provide air pressure. Specifically, as shown in the figure... Figure 3As shown, the positioning plate 6 has two air inlets 4 distributed vertically. The two air inlets 4 are connected together via a three-way adapter. Then, multiple adapters are used to connect the air pressure pipes to the corresponding connecting cylinder 2081 directly below. A vent valve 8 is installed in the middle, allowing multiple air pressure pipes to be connected together via the three-way adapter. An electric valve (not shown in the figure) is then installed. In use, when the electric valve is opened, high-pressure gas enters the connecting cylinder 2081 and the air inlets 4, thereby simultaneously rotating multiple support plates 202. After grinding, the positioning plate 6 can be moved by simply holding the ground pipe and opening the vent valve 8. It is easy to operate. It should be noted that the positioning plate 6 does not serve a clamping function; it only needs to be in contact with the pipe to be ground. A pressure control valve can be installed on the air inlet cylinder 4 to control the air pressure inside the air inlet cylinder 4 and prevent the positioning plate 6 from pressing tightly onto the pipe due to excessive air pressure. After installing the pressure control valve, even when grinding some thin pipes, it can effectively prevent the positioning plate 6 from pressing and deforming the thin pipe due to excessive internal pressure in the air inlet cylinder 4.

[0046] like Figure 1 and Figures 7 to 9 As shown, in order to prevent dust falling into the dust collection assembly 103 from accumulating to a certain amount and causing air pollution, the dust collection assembly 103 includes a drawer-type outer box 1031 installed on the frame 101. The top of the drawer-type outer box 1031 is vertically connected to a dust inlet pipe 1032 located below the mounting bracket 102. That is to say, the dust inlet pipe 1032 is the dust inlet. A drawer-type inner box 1033 is slidably arranged inside the drawer-type outer box 1031. The drawer-type inner box 1033 is equipped with a compression component 7 for compressing dust. That is to say, during the grinding process, the dust generated will enter the dust inlet pipe 1032. After the dust enters the dust inlet pipe 1032, the compression component 7 will compress the dust, thereby effectively preventing the dust from being raised.

[0047] like Figures 7 to 9As shown, in some embodiments, two partitions 701 are symmetrically installed on the drawer-type inner box 1033. The two partitions 701 divide the cavity of the drawer-type inner box 1033 into two sliding chambers 702 and a dust chamber 703. The bottom surface of the dust chamber 703 is evenly provided with air holes 7010 and a dust filter cloth. The material of the dust filter cloth is consistent with the structure of the dust removal cloth 7011 inside the existing vacuum cleaner. In order to prevent dust from being stirred up by the vibration of the equipment, preferably, a bottom of the drawer-type outer box 1031 can be provided with a... An opening allows the vent 7010 to be exposed to the outside air. An exhaust fan can be installed below the drawer-type outer box 1031 via a frame. A connecting cover (not shown in the figure) connects the exhaust fan's exhaust port to the bottom opening of the drawer-type outer box 1031. This effectively prevents dust from being stirred up by equipment vibration and efficiently draws dust from the pipes into the dust chamber 703. Sliding plates 704 are slidably installed in both sliding chambers 702, and a limiter is installed between the two sliding plates 704. Regarding the baffle 705, it should be explained that this application does not impose any other restrictions on the movement of the sliding plate 704. It can be any driving structure that can satisfy the movement of the sliding plate 704. Specifically, in this embodiment, a threaded rod 9 is horizontally and rotatably installed in one of the sliding cavities 702, and a small motor is built into one side wall of the drawer-type inner box 1033. The small motor is connected to the threaded rod 9. One of the sliding plates 704 is threaded onto the threaded rod 9. An extrusion plate 706 located in the dust chamber 703 is installed between the sliding plates 704. When the threaded rod 9 rotates, it will drive one of the sliding plates 704 to move. Because the two sliding plates 704 are connected by a limiting baffle 705, the extrusion plate 706 will also move. When dust falls into the dust chamber 703, the extrusion plate 706 can be moved to collect the dust together and squeeze it to prevent the dust from being thrown up. Since the threaded rod 9 is located in the sliding cavity 702, this can minimize the possibility of dust falling onto the threaded rod 9 and causing the sliding plate 704 to jam.

[0048] like Figures 7 to 9 As shown, to improve the dust compression and collection effect, the compression plate 706 is rotatably mounted between two sliding plates 704. One of the partition plates 701 has a receiving groove 707 on the side facing the dust chamber 703. A forcing strip 708 is elastically slidably inserted into the receiving groove 707. One end of the forcing strip 708 has a forcing inclined surface 709. When the compression plate 706 contacts the forcing inclined surface 709, the limiting baffle 705 restricts the rotation of the compression plate 706 and drives the forcing strip 708 to move into the receiving groove 707. Figure 7As shown, the squeezing plate 706 is located near the right side of the drawer-type inner box 1033. After the dust falls into the dust chamber 703, the squeezing plate 706 moves to the right and contacts the end face of the forcing strip 708, causing the squeezing plate 706 to rotate at a certain angle so that the bottom end of the squeezing plate 706 slides on the top surface of the forcing strip 708. When the squeezing plate 706 moves to the leftmost side and needs to move to the right, it will contact the forcing inclined surface 709. Because the limiting baffle 705 restricts the rotation of the squeezing plate 706, it will force the forcing strip 708 to move into the receiving groove 707. This ensures that the limiting baffle 705 remains vertical when moving from left to right, so that the dust is collected on the rightmost side of the drawer-type inner box 1033 and squeezed by the squeezing plate 706, improving the collection effect and facilitating subsequent dust processing.

[0049] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
