[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1 - Figure 6 This invention provides a technical solution: a processing fixture for a music teaching music stand, including a workbench 100, a sheet metal part 102 placed on top of the workbench 100, a cutting saw blade 104 vertically arranged above the workbench 100, and a pushing and limiting mechanism 200 for pushing and processing a frame 101. Using the pushing and limiting mechanism 200, the sheet metal part 102 can be automatically cut towards the cutting saw blade 104, reducing the danger of manual pushing and improving the safety and stability of music stand component processing. Simultaneously, it can limit and prevent deviation of the sheet metal part 102 during the cutting process, ensuring the flatness of the tangent line and accurate cutting dimensions. The pushing and limiting mechanism 200 includes a positioning baffle 201 for positioning the side of the frame 101, and a pushing pressure plate placed on the upper surface of one end of the frame 101. 202, the push plate 202 is L-shaped, which facilitates pressing the end of the plate part 102 and facilitates the movement and cutting of the plate part 102. The top of the push plate 202 is provided with a lifting cylinder 205 to drive its lifting and lowering. The height of the push plate 202 can be changed by using the lifting cylinder 205 to adapt to plate parts 102 of different thicknesses. The top of the positioning baffle 201 is slidably provided with a guide sleeve 206 to support the lifting cylinder 205. The front surface of the guide sleeve 206 is provided with a stabilizing seat 208 to support the lifting cylinder 205. The upper end of the positioning baffle 201 can be I-shaped and slides with the guide sleeve 206 to play a limiting role. The rear surface of the positioning baffle 201 is provided with a moving component 203 to drive the guide sleeve 206 to move. The moving component 203 can drive the guide sleeve 206 and the push plate 202 to move. A long rack 2031 is provided on the rear surface of the positioning baffle 201 along its length. The long rack 2031 is relatively long, which facilitates the subsequent movement of the guide sleeve 206 along the length of the positioning baffle 201. A drive gear 2033 that meshes with the long rack 2031 is provided on the rear surface of the guide sleeve 206. A limiting component 204 is provided on the left side of the cutting saw blade 104. The limiting component 204 can be located on the front surface of the cut plate part 102 to limit and prevent deviation, thus preventing the plate part 102 from shifting forward. The limiting component 204 includes a limiting baffle 2041 that vertically limits the front surface of the frame 101. The thickness of the limiting baffle 2041 is adapted to the thickness of the cutting saw blade 104.

[0021] In this embodiment, preferably, the moving component 203 further includes a drive motor 2032 mounted on the rear surface of the guide sleeve 206. An output shaft is provided between the lower end of the drive motor 2032 and the drive gear 2033. The drive motor 2032 drives the output shaft and the drive gear 2033 to rotate and mesh with the long rack 2031.

[0022] In this embodiment, preferably, a support frame 103 is vertically arranged on the rear surface of the workbench 100. The support frame 103 can be L-shaped, and a cutting head is vertically arranged at the front end of the support frame 103. The internal structure of the cutting head is all existing technology. The lower surface of the front end of the support frame 103 is connected to the cutting saw blade 104. The upper surface of the limiting baffle 2041 is fixed to the side of the front end of the support frame 103. Multiple guide rollers 2042 are rotatably arranged inside the lower end of the limiting baffle 2041. The diameter of the guide rollers 2042 is slightly larger than the thickness of the limiting baffle 2041, so as to facilitate the contact between the guide rollers 2042 and the surface of the plate part 102, reduce frictional resistance, and facilitate the movement and cutting of the plate part 102.

[0023] In this embodiment, preferably, an adjustment component 207 is provided between the lower end of the lifting cylinder 205 and the pushing plate 202. Using the adjustment component 207, the position of the pushing plate 202 can be adjusted according to the length of the plate part 102, so that the pushing plate 202 is located at the end of the plate part 102, thereby expanding the pushing and cutting range of the plate part 102. A horizontal rail 2071 is provided at the lower end of the lifting cylinder 205. The cross section of the horizontal rail 2071 can be T-shaped. A guide sleeve 2072 is provided on the upper surface of the pushing plate 202 and sleeved on the horizontal rail 2071. A limit rod 2073 is provided between the guide sleeve 2072 and the horizontal rail 2071. The limit rod 2073 is threadedly connected to the guide sleeve 2072, which can limit and fix the position of the guide sleeve 2072.

[0024] In summary, during use, the sheet metal part 102 can be placed on the upper surface of the workbench 100, with its rear surface adhering to the front surface of the positioning baffle 201 to ensure proper contact. Simultaneously, based on the processing dimensions of the sheet metal parts 102 from the same batch, the push plate 202 can be moved along the horizontal rail 2071 until it is positioned at the end of the sheet metal part 102. The limiting rod 2073 is then rotated to fix the guide sleeve 2072 to the horizontal rail 2071, thus fixing the position of the push plate 202. Next, the lifting cylinder 205 is activated, extending its internal piston rod to move the push plate 202 downwards, allowing it to stably press the end of the sheet metal part 102. The drive motor 2032 then operates, driving the drive gear 2033 to rotate. The drive gear 2033 meshes with the long rack 2031, rotating along the long rack 2031. 1. The movement drives the guide sleeve 206, lifting cylinder 205, and pushing pressure plate 202 to move to the left, pushing the plate part 102 to move to the left and closer to the cutting saw blade 104. The plate part 102 is cut into a suitable size, and the limiting baffle 2041 is located between the cuts of the plate part 102. The guide roller 2042 contacts the cut surface of the plate part 102 and rotates as the plate part 102 moves, reducing the frictional resistance of the plate part 102. At the same time, the left end of the plate part 102 shifts outward, ensuring the stable movement of the plate part 102 and preventing unevenness of the cut surface. The entire plate part 102 cutting process does not require manual pushing, preventing accidental injury and increasing the processing stability and safety of the plate part 102. Multiple plate parts 102 are processed stably and safely, facilitating the processing of the overall music stand and improving assembly efficiency.

[0025] Example 2 Reference Figure 7 and Figure 8 This is the second embodiment of the present invention.

[0026] In this embodiment, preferably, a grinding mechanism 300 is provided at the left end of the workbench 100. By providing the grinding mechanism 300, the four circumferences and corners of the sheet metal 102 can be uniformly ground after cutting. It can also adapt to sheet metal 102 of different sizes within a certain range, resulting in a smooth and even surface and corners of the final output sheet metal 102. This reduces subsequent individual processing steps, improves the overall processing efficiency of the sheet metal 102, and saves the processing time of the entire music stand. The grinding mechanism 300 includes a front grinding component 303 vertically located on the left side of the workbench 100. The front grinding component 303 and the side grinding component 302 have the same structure, with the only difference being... The difference lies in the angle setting of the electric telescopic rod 3022. In the forward grinding component 303, the electric telescopic rod 3022 is installed at the quadrant point of the mounting ring 3021, while the electric telescopic rod 3022 in the side grinding component 302 deviates from the electric telescopic rod 3022 in the forward grinding component 303 by a certain angle. The outer end of the electric telescopic rod 3022 is equipped with a motor to drive its rotation. The side grinding component 302 is provided on the left side of the forward grinding component 303, and multiple connecting plates 304 are arranged circumferentially between the two. Two support frames 301 are provided between the connecting plates 304 and the worktable 100. The support frames 301 can simultaneously and stably support the side grinding component 302 and the forward grinding component 303.

[0027] In this embodiment, preferably, the side grinding component 302 includes a mounting ring 3021. Multiple electric telescopic rods 3022 are provided on the circumferential surface of the mounting ring 3021. The electric telescopic rods 3022 can change the distance between the grinding wheel 3023 and the corner of the plate component 102. The inner end of the electric telescopic rod 3022 is provided with a grinding wheel 3023, which can grind the corner of the plate component 102. A stabilizing frame 3024 is provided between the electric telescopic rod 3022 and the mounting ring 3021, and a bearing is embedded between the stabilizing frame 3024 and the electric telescopic rod 3022 to facilitate rotation of the motor and increase the installation strength of the electric telescopic rod 3022.

[0028] In this embodiment, preferably, the electric telescopic rod 3022 has an inner rod 3025 inside, which is rotatably connected to the grinding wheel 3023, making it easy to change the angle of the grinding wheel 3023. At the same time, the grinding wheel 3023 is easy to disassemble and replace. The grinding wheel 3023 in the positive grinding component 303 is also detachable and replaceable. Two lugs 3026 are vertically arranged on the outer surface of the grinding wheel 3023, located outside the inner rod 3025. A rotating rod 3027 is arranged between the lugs 3026 and the inner rod 3025. A threaded ring 3028 is screwed onto the outer end of the rotating rod 3027. The threaded ring 3028 contacts the lugs 3026, which can limit and fix the rotating rod 3027 to prevent abnormal rotation. The threaded ring 3028 is disengaged from the rotating rod 3027, making it easy to disassemble and replace the grinding wheel 3023 and the inner rod 3025.

[0029] In summary, during use, the entire grinding mechanism 300 is installed on the left side of the worktable 100. The sheet metal part 102, after being cut, is pushed to the left and gradually positioned within the grinding component 303. Based on the dimensions of the sheet metal part 102, the electric telescopic rod 3022 in the grinding component 303 operates, driving the grinding wheels 3023 to move. The four grinding wheels 3023 are positioned on the four circumferential surfaces of the sheet metal part 102, and the motor operates to rotate the electric telescopic rod 3022 and the grinding wheels 3023 in the grinding component 303. The grinding wheels 3023 grind the four circumferential surfaces of the sheet metal part 102, and the distance between the four grinding wheels 3023 is adjustable. Within a certain range, it can adapt to different sizes of sheet metal parts 102. For the larger area of ​​the circumferential surface, the appropriate grinding wheel 3023 can be replaced. After the circumferential surface is ground, the sheet metal parts 102 continue to move to the left. At this time, the distance and position between the grinding wheels 3023 in the side grinding component 302 are adapted to the corner position of the sheet metal parts 102. As the sheet metal parts 102 move, the motor drives the electric telescopic rod 3022 and the grinding wheel 3023 to rotate and grind the corners of the sheet metal parts 102. This allows the final output of the sheet metal parts 102 to undergo cutting, circumferential surface and corner processing, reducing the steps and troubles of subsequent processing and improving the processing efficiency of the music stand parts.

[0030] Example 3 Reference Figure 9 and Figure 10 This is the third embodiment of the present invention.

[0031] In this embodiment, preferably, a fixed rail 305 is provided on the left side of the workbench 100, and a limiting sleeve 306 is embedded on the left end of the support frame 301. The limiting sleeve 306 moves along the fixed rail 305, which facilitates changing the position of the entire grinding mechanism 300, making it easy to adapt to different sizes of sheet metal parts 102, and ensuring that the processed sheet metal parts 102 are located at the center of the grinding mechanism 300. A limiting bolt 307 is provided between the fixed rail 305 and the limiting sleeve 306, which can limit and fix the position of the limiting sleeve 306.

[0032] In this embodiment, preferably, the upper front and rear surfaces of the positioning baffle 201 are provided with guide grooves 2011 along its length, which allows the upper end of the positioning baffle 201 to form an I-shape, facilitating sliding engagement with the guide sleeve 206 without disengaging vertically. The surface of the workbench 100 is provided with two rectangular sliding holes 2012, and the lower surface of the positioning baffle 201 is provided with a fixed slide rod 2013 that passes through the rectangular sliding holes 2012 and protrudes below. The fixed slide rod 2013 can move the positioning baffle 201 by moving in the rectangular sliding holes 2012, which can adjust the distance between the positioning baffle 201 and the cutting saw blade 104 and can be adapted to different sizes of plate parts 102. The lower end of the fixed slide rod 2013 is screwed with a limiting ring 2014 that contacts the lower surface of the workbench 100. The diameter of the limiting ring 2014 is larger than the width of the rectangular sliding hole 2012, which facilitates limiting the position of the fixed slide rod 2013.

[0033] In this embodiment, preferably, a frame 101 is provided at the bottom of the workbench 100.

[0034] In summary, during use, depending on the size of the sheet metal part 102 to be cut, the positioning baffle 201 and the fixed slide rod 2013 can be moved in the rectangular sliding hole 2012 to adjust the distance between the positioning baffle 201 and the cutting saw blade 104. When the distance is appropriate, the limiting ring 2014 is rotated to make it contact the lower surface of the worktable 100, thus fixing the position of the fixed slide rod 2013 and the positioning baffle 201. In order to adapt to the size of the sheet metal part 102 after cutting, the position of the grinding mechanism 300 also needs to be changed. The support frame 301 and the limiting sleeve 306 can be moved along the fixed rail 305 to change the position of the center of the front grinding component 303 and the side grinding component 302. After aligning with the cut sheet metal part 102, the position of the support frame 301 and the limiting sleeve 306 is fixed by the limiting bolt 307.

[0035] Example 4 This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0036] In use, the positioning baffle 201 is used to position the sheet metal part 102, and then the moving component 203 drives the pressure plate 202 to move, pushing the sheet metal part 102 to the left for cutting. The limiting component 204 is used to limit and prevent the sheet metal part 102 from deviating after cutting, ensuring the flatness and stability of the sheet metal part 102 after cutting. After cutting, the sheet metal part 102 moves to the left and is first processed by the forward grinding component 303 on the four circumferences of the sheet metal part 102. Then, the side grinding component 302 is used to process the edges and corners of the sheet metal part 102. Finally, the surface of the sheet metal part 102 is smooth and flat, reducing the subsequent processing steps and saving the processing time of the sheet metal part 102, thereby improving the overall processing efficiency of the music stand.
