The upper sides of the three loading and unloading components 5 are all provided with clamping components 6. Through the provided clamping components 6, the surfaces of saxophone bodies of different sizes can be clamped, and then, with the auxiliary action of the loading and unloading components 5, the loading and unloading components 5 can push the saxophone body to be polished into the clamping components 6 for clamping and limiting, and the loading and unloading components 5 can collect the debris generated during grinding, and at the same time, with the cooperation of the pressing component 9, the debris generated during grinding can be prevented from splashing around, thereby optimizing the processing environment;

[0034] A fixing plate 7 is provided at the upper end of the driving assembly 4, and a top plate 8 is fixedly connected to the upper end of the fixing plate 7. A pressing assembly 9 is slidably installed on the rear side of the fixing plate 7. The driving assembly 4 is provided to start the clamping assembly 6 to rotate, and the pressing assembly 9 is provided to close the pressing assembly 9 when the pressing assembly 9 is pressed downward, and then the clamping assembly 6 is assisted to grind the saxophone body. When the pressing assembly 9 moves downward, the loading and unloading assembly 5 can be assisted to eject the debris collected inside it, and after the grinding process is completed, when the pressing assembly 9 is pulled upward, the loading and unloading assembly 5 can be assisted to eject the saxophone body clamped in the inner cavity of the clamping assembly 6, without the need for manual material collection and pouring out of the debris, thereby improving the processing efficiency.

[0035] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve the effect of automatically pushing the plastic saxophone body to be processed into the clamping assembly 6 for clamping.

[0036] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10 The loading and unloading assembly 5 includes three material storage boxes 51 distributed in a linear array and fixedly connected to the lower end of the operating table 3. The left side walls and the right side walls of the inner surfaces of the three material storage boxes 51 are slidably connected with push plates 52. The upper ends of the three push plates 52 are fixedly connected with threaded blocks. The front parts of the upper ends of the three threaded blocks are fixedly connected with top plates 1 53. The upper parts of the rear ends of the three threaded blocks are fixedly connected with supporting plates 54. The upper rear edges of the upper ends and the rear edges of the lower ends of the three supporting plates 54 are fixedly connected with top plates 2 55. The lower ends of the three top plates 2 55 located on the lower side are fixedly connected with blocking plates 56. The inner surfaces of the three threaded blocks are threadedly connected with threaded rods 57. The three threaded blocks are respectively slidably connected to the inner surfaces of the blanking holes 32 on the same side. The rear ends of the three threaded rods 57 pass through the rear end of the mounting box 41 and are fixedly connected to the cylindrical gears 44 on the same side.

[0037] Furthermore, the pressing assembly 9 includes a pressing plate 91 slidably connected to the rear end of the fixing plate 7, a rectangular column 92 is fixedly connected to the middle of the upper end of the pressing plate 91, the rectangular column 92 penetrates the top plate three 8 and extends to the outside, a handle 93 is fixedly connected to the upper end of the rectangular column 92, a plurality of guide cylinders 94 are fixedly connected to the lower end of the pressing plate 91 in a linear array, and a plurality of guide cylinders 94 are slidably connected to the inner surfaces of the plurality of guide cylinders 94, and three arc-shaped grinding plates 96 distributed in a linear array are provided on the lower side of the pressing plate 91, the upper ends of the three arc-shaped grinding plates 96 are respectively fixedly connected to the lower ends of the plurality of guide cylinders three 95, and a spring three 97 is fixedly connected to the ends of the three arc-shaped grinding plates 96 and the plurality of guide cylinders 94 that are close to each other.

[0038] Furthermore, the lower end of the pressing plate 91 is fixedly connected to the upper ends of the three racks 43, and three linear array-distributed slide grooves 71 are provided at the rear end of the fixed plate 7. The three racks 43 are slidably connected to the inner cavities of the slide grooves 71 on the same side through connecting blocks.

[0039] Furthermore, the driving assembly 4 includes a mounting box 41 fixedly connected to the front end of the operating table 3, three rectangular holes 42 are opened on the rear side of the bottom wall of the mounting box 41, the three rectangular holes 42 are distributed in a linear array and penetrate the upper and lower ends of the mounting box 41, the inner surfaces of the three rectangular holes 42 are all slidably connected with racks 43, and the middle part of the front side wall of the inner surface of the mounting box 41 is rotatably connected with three cylindrical gears 44 distributed in a linear array, and the three cylindrical gears 44 are respectively meshed with the three racks 43. The upper part of the front side wall of the inner surface of the mounting box 41 is rotatably connected to the There are three bevel gears 1 45 distributed in a linear array, three support rods 46 distributed in a linear array are fixedly connected to the middle of the bottom wall of the installation box 41, and a transmission rod 47 is connected to the upper part of the inner surfaces of the three support rods 46 for common rotation, a mounting seat 48 is fixedly connected to the rightmost part of the middle of the bottom wall of the installation box 41, a motor 49 is fixedly connected to the upper end of the mounting seat 48, and three bevel gears 2 40 distributed in a linear array are fixedly connected to the outer surface of the transmission rod 47, and the three bevel gears 2 40 are respectively meshed with the bevel gear 1 45 on the same side.

[0040] By holding the handle 93 and pulling it upward, the handle 93 drives the rectangular column 92 fixedly connected thereto to slide upward at the same time. As can be seen from the above, the upper end of the pressing plate 91 is fixedly connected to the lower end of the rectangular column 92, and the lower end of the pressing plate 91 is fixedly connected to the upper ends of the three racks 43. Therefore, when the pressing plate 91 moves upward with the rectangular column 92, the pressing plate 91 can drive the three racks 43 fixedly connected at its lower end to slide upward in the corresponding slide grooves 71 under the limiting action of the connecting block.

[0041] As the three racks 43 move downward with the pressing plate 91, the three cylindrical gears 44 mesh with the three racks 43 respectively. Therefore, as the three racks 43 move downward, the cylindrical gears 44 meshing with the three racks 43 can be driven to rotate, and the three racks 43 can slide in the corresponding rectangular holes 42. When the three cylindrical gears 44 rotate, the rear ends are fixedly connected to the three threaded rods 57 respectively. Therefore, the three cylindrical gears 44 respectively drive the corresponding threaded rods 57 to rotate, and the threaded blocks on the same side are respectively threadedly connected to the threaded rods 57 on the same side, and the threaded blocks on the same side are respectively threadedly connected to the threaded rods 57 on the same side. The blocks are respectively slidably connected to the blanking holes 32 on the same side, so that when the threaded rod 57 on the same side rotates, it can drive the threaded block threadedly connected thereto to move backward, and then the threaded block drives the top plate 1 53 and the carrying plate 54 fixedly connected to its upper end to move backward at the same time, and then after the three carrying plates 54 are simultaneously moved out of the upper ends of the corresponding storage boxes 51, the plastic saxophone bodies that need to be polished can be placed on the upper ends of the three carrying plates 54 in turn. Since the carrying plates 54 are arranged in a U-shaped shape, the middle part thereof is hollow, which can prevent the plastic saxophone body from being unable to fall downward during the polishing process;

[0042] After the plastic saxophone body is placed on the upper side of the three supporting plates 54 in sequence, the grip 93 can be held downward to press the pressing plate 91 downward. Then, the downward process is opposite to the above process, so that the three threaded rods 57 can respectively drive the threaded plates threadedly connected thereto to move forward.

[0043] Prior to this, the plastic saxophone body needs to be partially inserted into the clamping assembly 6, and then the carrying plate 54 can drive the plastic saxophone body placed on the upper end to be clamped by the top plate 2 55 into the clamping assembly 6;

[0044] According to the above, when the pressing plate 91 moves upward, it can prompt the pushing plate 52 to move backward, and at the same time drive the blocking plate 56 fixedly connected to the lower end of the top plate 55 to no longer block the corresponding storage box 51, and the three pushing plates 52 can respectively push out the debris stored in the inner cavity of the corresponding storage box 51.

[0045] However, when the push plate 52 moves backward, the finished plastic saxophone body can be ejected from the top plate 53.

[0046] This achieves the integrated effect of material loading and blanking, and improves subsequent processing efficiency.

[0047] Embodiment 3: This embodiment is based on Embodiment 2 and is for achieving the purpose of clamping and polishing plastic saxophone bodies of different sizes.

[0048] For details, see Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.11 Three arc holes 31 penetrating the front end of the operating platform 3 are provided in a linear array at the rear end of the operating platform 3, a blanking hole 32 communicating with the lower end of the operating platform 3 is provided in the middle of the inner surface of the three arc holes 31, and a plurality of guide holes 33 distributed in a linear array are provided on the left and right walls of the inner surfaces of the three arc holes 31.

[0049] Furthermore, the clamping assembly 6 includes a guide column 61 slidably connected to the inner surfaces of the guide holes 33, the upper ends of the guide columns 61 on the same side are commonly fixedly connected to an outer arc plate 62, the lower parts of the outer surfaces of the two outer arc plates 62 on the same side, which are away from each other, are commonly fixedly connected to the arc holes 31 on the same side, and the springs 63 are located on the outsides of the guide columns 61, the inner surfaces of the two outer arc plates 62 on the same side are provided with a plurality of arc grooves 64 distributed in a linear array, the front side walls and the rear side walls of the inner surfaces of the arc grooves 64 are commonly rotatably connected to a plurality of auxiliary rollers 65 distributed in a linear array, the upper sides of the two outer arc plates 62 on the same side are provided with a support assembly 66, three groups of symmetrically distributed partitions 67 are fixedly connected to the upper end of the operating table 3, the two partitions 67 on the same side are respectively located on the left and right sides of the arc holes 31 on the same side, and the top plate 1 53 and the top plate 2 55 on the same side are both located between the two outer arc plates 62 on the same side.

[0050] Furthermore, the support assembly 66 includes a driving roller 661 fixedly connected to the front end of the bevel gear 45, a plurality of guide holes 662 are provided in a circular array on the outer surface of the driving roller 661, and guide columns 663 are slidably connected to the inner surfaces of the plurality of guide holes 662. The driving roller 661 is provided with four inner arc plates 664 in a circular array on the outer surface of the driving roller 661, and the middle parts of the inner surfaces of the four inner arc plates 664 are respectively fixedly connected to the plurality of guide columns 663 on the same side, and the inner surfaces of the four inner arc plates 664 and the ends close to the driving roller 661 are commonly fixedly connected with a plurality of springs 665, and the plurality of springs 665 are respectively located on the outside of the plurality of guide columns 663.

[0051] Furthermore, the lower parts of the outer surfaces of the three arc-shaped grinding plates 96 are all fixedly connected with grinding sandpaper.

[0052] As can be seen from the above, when the top plate 2 55 pushes the plastic saxophone body that needs to be processed and polished into the drive assembly 4, it is necessary to insert part of it into the drive assembly 4, and the specific operation steps are as follows;

[0053] The tube body of the plastic saxophone is inserted into the gap formed between the four inner arc plates 664 and the two outer arc plates 62. Since the rear ends of the two outer arc plates 62 and the four inner arc plates 664 are all arranged in an inclined shape, the purpose of setting them in this shape is to make the insertion of the saxophone tube body into the gap smoother and not blocked. When the saxophone tube body is inserted into the gap, the two outer arc plates 62 and the four inner arc plates 664 will be squeezed at the same time according to the different diameters of the tube body, and the multiple springs 63 fixedly connected to the outer surfaces of the two outer arc plates 62 will be squeezed, and the two outer arc plates 62 can drive the multiple guide posts 63 fixedly connected to the outer surfaces thereof. 61 moves inward in the corresponding guide hole 1 33, and then the inner surfaces of the two outer arc plates 62 are forced to fit with the outer surface of the tube body under the force of the plurality of springs 1 63 to expand outward. At the same time, the four inner arc plates 664 are respectively driven by the plurality of springs 2 665 to which the inner surfaces are fixedly connected, and then the four inner arc plates 664 are first driven to contract inward. Then, after the tube body is fully entered, the plurality of springs 2 665 release the compressed force outward, and the plurality of guide columns 2 663 play a guiding role in the inner cavity of the plurality of guide holes 2 662, so that the four inner arc plates 664 are expanded outward, and then the inner wall of the tube body is supported and fixed;

[0054] As can be seen from the above, when the pressing plate 91 is pressed downward, the three racks 43 can be driven to move downward at the same time. When the three racks 43 move downward, the three cylindrical gears 44 meshing with each other can be caused to rotate, and then the carrying plate 54 can be driven to move backward. When the carrying plate 54 moves backward, the top plate 55, the blocking plate 56 and the pushing plate 52 can be driven to move backward at the same time. As can be seen from the above, the top plate 1 53 and the top plate 2 55 on the same side are both located between the two outer arc plates 62 on the same side. Therefore, the top plate 2 55 can completely push the rear end of the tube body into the gap formed between the four inner arc plates 664 and the two outer arc plates 62. At the same time, the pressing plate 91 drives the several guide cylinders 94 fixedly connected at the lower end thereof downward at the same time, and the inner surfaces of the guide cylinders 94 are slidably connected with the guide pillars 3 95, and the lower ends of the several guide pillars 3 95 are fixedly connected with the arc-shaped grinding plates 96, and the three arc-shaped grinding plates 96 and the several guide cylinders 94 are commonly fixedly connected with the springs 3 97, so that when the arc-shaped grinding plates 96 are attached to the surface of the pipe body, they can be self-contracted according to the different diameters of the pipe body, and when the arc-shaped grinding plates 96 are attached to the surface of the pipe body, the partitions 67 on both sides thereof just play the role of blocking the two sides, which can prevent the debris generated during processing from flying out from both sides;

[0055] When the three arc-shaped grinding plates 96 are all fitted on the corresponding surfaces of the tube body, the motor 49 can be started so that the output end of the motor 49 drives the transmission rod 47 to rotate through the coupling, and the three bevel gears 2 40 fixedly connected to the surface of the transmission rod 47 are respectively meshed with the three bevel gears 1 45, so that when the transmission rod 47 rotates, the three bevel gears 1 45 also rotate accordingly. As can be seen from the above, the front ends of the three bevel gears 1 45 are fixedly connected to the three driving rollers 661, so that when the driving rollers 661 rotate, the fixed tube body can be driven to rotate. When the tube body rotates, in order to avoid the tube body from getting stuck during rotation, the present solution is to open a plurality of arc-shaped grooves 64 distributed in a linear array on the inner surfaces of the two outer arc-shaped plates 62 on the same side, and the front side walls and the rear side walls of the inner surfaces of the plurality of arc-shaped grooves 64 are rotatably connected to a plurality of auxiliary rollers 65 distributed in a linear array, so that when the tube body rotates, the plurality of auxiliary rollers 65 play a role of assisting the rotation.

[0056] When the tube body rotates, since the lower parts of the outer surfaces of the three arc-shaped grinding plates 96 are fixedly connected with grinding sandpaper, the surface of the tube body during the rotation process can be polished;

[0057] The debris generated during the grinding process can fall down from the opening of the drop hole 32 and the supporting plate 54 to the inner cavity of the storage box 51 for storage. When the processing is completed, it is only necessary to repeat the operation of the above-mentioned embodiment 2, and move the blocking plate 56 and the pushing plate 52 outward at the same time, so that the pushing plate 52 pushes the debris out of the inner cavity of the storage box 51. At the same time, the supporting plate 54, under the action of the top plate 53, pushes out the tube body with the processed upper part. The specific operating steps are the same as the operating steps in the embodiment 2, so this embodiment will not be elaborated in detail.

[0058] The grinding sandpaper mentioned above is a conventional design in the prior art, and is only required to grind the surface of the plastic saxophone body. The specific mesh number required for grinding can be adjusted according to actual production needs, so this solution will not be elaborated in detail.
