Description

Technical Field

[0001] The invention relates to the technical field of speaker processing, in particular to a fixing device for processing a speaker shell. Background Art

[0002] A horn is a modern electroacoustic component that converts electrical signals into sound. It can also be called a loudspeaker. It is generally used for sound amplification and publicity. The horn is thin at the top and thick at the bottom, and the bottom opening is open to the surroundings to amplify the sound. At present, when operators process the horn shell, they often need to use a fixing device to facilitate the processing of the operator. Although the fixing device in the prior art can basically fix the horn shell in actual use, it generally uses the operator to rotate the threaded rod to make the clamping block move to clamp the horn shell. The operation is cumbersome and inconvenient for the operator to use, which in turn affects the operator's work efficiency. Therefore, it needs to be improved.

[0003] A fixing device for processing a speaker shell provided by publication number "CN218427945U" comprises a base, the top of the base is fixedly connected to a shell, the middle of the inner cavity of the shell is fixedly connected to a square column, the left and right sides of the outer side of the square column are movably sleeved with movable columns, the left and right sides of the top of the shell are provided with notches, and the top of the movable column is movably connected to a connecting column. The utility model is provided with a clamping block 1, a connecting plate, a driving motor, a connecting shaft and a round block 1. When the driving motor is running, the connecting shaft and the round block 1 will rotate through the rotating shaft, and the cooperation between the connecting plate and the round block 1 will make the two connecting plates move towards each other, which will make the two movable columns move towards each other as a whole, and the cooperation between the two clamping blocks 1 can fix the rough part of the outer side of the speaker shell, and the operation is simple, so it is convenient for operators to use.

[0004] However, the above device still has the following problems during implementation:

[0005] 1. The clamping and fixing of the speaker still uses the blocks (or other clamping plates, etc.) on both sides.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-11 , the present invention provides a technical solution:

[0042] Embodiment 1:

[0043] A fixing device for processing a speaker shell, comprising a processing base 1 and a first clamping bracket 2 and a second clamping bracket 14 arranged above the processing base 1, the first clamping bracket 2 and the second clamping bracket 14 are used to clamp and fix the speaker to be processed, the first clamping bracket 2 is fixed, the second clamping bracket 14 is sliding, and a moving component is connected between the second clamping bracket 14 and the processing base 1;

[0044] In this embodiment, the speaker is clamped and fixed by using the first clamping bracket 2 and the second clamping bracket 14. In order to adapt to speakers of different sizes, the first clamping bracket 2 and the second clamping bracket 14 are both configured as liftable structures, and the second clamping bracket 14 can move within the processing base 1. By changing the distance between the first clamping bracket 2 and the second clamping bracket 14, the matching speaker can be better fixed.

[0045] Several groups of clamping components are arranged in the first clamping bracket 2 and the second clamping bracket 14, and the clamping components include a suction cup 6 and a suction cup connecting rod 13. The suction cup 6 and the suction cup connecting rod 13 are connected by a universal connecting sleeve 8, and the suction cup connecting rod 13 is slidably installed in the first clamping bracket 2 and the second clamping bracket 14 respectively. The universal connecting sleeve 8 and the first clamping bracket 2 and the second clamping bracket 14 are respectively connected with a first compression spring 7. The elastically connected suction cup 6 is attached to the outer wall of the speaker, so as to achieve clamping and fixing of the speaker, avoid clamping wear on the speaker during processing, increase the clamping area of ​​the speaker, and make the speaker fixing structure stable during processing.

[0046] Specifically, first pull the distance between the first clamping bracket 2 and the second clamping bracket 14 to be sufficient to place the speaker on the processing base 1. When the speaker is placed between the first clamping bracket 2 and the second clamping bracket 14, move the second clamping bracket 14 so that the first clamping bracket 2 and the second clamping bracket 14 clamp and fix the speaker. When the first clamping bracket 2 and the second clamping bracket 14 are close to the speaker, since the shape of the speaker is mostly a cone or an irregular cone structure, each group of suction cups 6 can be attached to the outer wall of the speaker through the elastic connection of the first compression spring 7, thereby increasing the contact area between the clamping assembly and the speaker, ensuring the clamping force of the clamping assembly, and thus making the clamping assembly stable in fixing the speaker structure.

[0047] It should be noted that the first clamping bracket 2 and the second clamping bracket 14 are provided with through holes 19 whose number matches the suction cups 6 , and the suction cup connecting rods 13 slide in the through holes 19 .

[0048] It should be noted that the first clamping bracket 2 and the second clamping bracket 14 are not limited to flat plate structures, and can be configured as arc plates as required to better fit the outer contour of the speaker.

[0049] The lifting assembly includes a lifting screw 10 and a transmission assembly for driving the lifting screw 10 to rotate. The transmission assembly is connected to a lifting motor 12. The transmission assembly includes a lifting screw 10 and a drive sleeve 18 threadedly connected to the surface of the lifting screw 10. The drive sleeve 18 is rotatably installed in the processing base 1 through a bearing. The output shaft end of the lifting motor 12 is rotatably installed in the processing base 1, and two sets of synchronous pulleys 11 are fixedly installed on the output shaft end of the lifting motor 12. The outer wall of the drive sleeve 18 is also fixedly installed with a synchronous pulley 11. A synchronous belt is connected to the synchronous pulleys 11, and a protective cover 28 is arranged on the outside of the synchronous belt.

[0050] Specifically, the lifting motor 12 is started, and the lifting motor 12 drives the two sets of synchronous pulleys 11 at the output shaft end to rotate. The synchronous pulleys 11 are connected through the synchronous belt and the synchronous pulleys 11 arranged on the surface of the lifting screw 10, thereby driving the driving sleeve 18 to rotate. Since the rotation of the driving sleeve 18 is limited within the processing base 1, and the driving sleeve 18 and the lifting screw 10 are threadedly connected, the rotation of the driving sleeve 18 can drive the lifting screw 10 to drive the first clamping bracket 2 and the second clamping bracket 14 to adjust the height.

[0051] The bottoms of the first clamping bracket 2 and the second clamping bracket 14 are both slidably installed above the processing base 1 through the guide rod 9, and the first clamping bracket 2 and the second clamping bracket 14 are both slidably set above the processing base 1 through the lifting assembly.

[0052] It should be noted that since the first clamping bracket 2 and the second clamping bracket 14 both have a certain width and a plurality of groups of elastically connected suction cups 6 are arranged inside the first clamping bracket 2 and the second clamping bracket 14, in order to ensure the stability of the lifting structure of the first clamping bracket 2 and the second clamping bracket 14, a guide rod 9 is provided as a support, and the guide rod 9 and the processing base 1 are slidably connected to further ensure the stability of the speaker fixing structure.

[0053] Since the second clamping bracket 14 needs to realize both lifting and horizontal movement, the following structure is set:

[0054] The top end of one of the two groups of lifting screws 10 is rotatably connected to the first clamping bracket 2, and a connecting block 25 and a first linear guide 26 are arranged between the top end of the other group of lifting screws 10 and the second clamping bracket 14. The first linear guide 26 is rotatably connected to the top end of the lifting screw 10, and the moving block on the first linear guide 26 is connected to the bottom surface of the second clamping bracket 14 through the connecting block 25.

[0055] In this embodiment, a connecting block 25 and a first linear guide rail 26 are provided between the lifting screw 10 and the second clamping bracket 14. The connecting block 25 and the lifting screw 10 are rotatably connected, and the first linear guide rail 26 is used to support the connecting block 25, thereby realizing the lifting and lowering of the second clamping bracket 14, and enabling the second clamping bracket 14 to be lifted and lowered while rotating.

[0056] It should be noted that, in order to ensure the stability of the connection structure, a sleeve with reinforcing ribs 27 is provided at the bottom of the first linear guide rail 26, and the top end of the lifting screw 10 at the bottom of the second clamping bracket 14 is rotatably connected in the sleeve.

[0057] The surfaces of the two groups of guide rods 9 at the bottom of the second clamping bracket 14 are both slidably connected with a linkage frame 15, a sliding guide groove 17 is opened in the processing base 1 at the sliding position of the guide rod 9, a first electric slide 16 is arranged on one side of the sliding guide groove 17, and the linkage frame 15 and the slider on the first electric slide 16 are fixedly connected.

[0058] In this embodiment, the guide rod 9 is connected by the linkage frame 15, which does not affect the guide rod 9 following the lifting of the second clamping bracket 14, and the guide rod 9 and the first electric slide 16 are connected by the linkage frame 15, which does not affect the sliding of the second clamping bracket 14.

[0059] It should be noted that a sliding guide groove 17 is provided in the processing base 1 to provide a moving space for the guide rod 9 .

[0060] The first clamping bracket 2 and the second clamping bracket 14 are fixedly installed with a speaker edge limit plate 3 on the opposite side, and a limit groove 4 is provided in the speaker edge limit plate 3. When the first clamping bracket 2 and the second clamping bracket 14 fix the speaker, the edge of the speaker falls into the two groups of limit grooves 4, and the speaker is clamped and fixed in cooperation with the clamping assembly.

[0061] See also Fig.12 , indicating the specific location of the speaker edge.

[0062] Embodiment 2:

[0063] Based on Example 1, when the edge thickness of the speaker changes, a single speaker edge limit plate 3 is not sufficient to complete the clamping and fixing of the speaker edge. Therefore, in this embodiment, a quick disassembly and assembly component is provided between the speaker edge limit plate 3 and the first clamping bracket 2 and the second clamping bracket 14 respectively. According to the size of the speaker edge, the speaker edge limit plate 3 can be quickly replaced to adapt to the speaker to be processed, thereby ensuring the stability of the fixed structure. The quick disassembly and assembly component includes a spline shaft 5 and a spline sleeve 20. The spline sleeve 20 is fixedly connected to the first clamping bracket 2 and the second clamping bracket 14. The spline shaft 5 is slidably inserted in the spline sleeve 20. One side of the first clamping bracket 2 and the second clamping bracket 14 is located on one side of the spline sleeve 20 and is elastically slidably connected with a positioning rod 21. The positioning rod 21 passes through the spline shaft 5 and the spline sleeve 20. A positioning block 24 is fixedly installed on one side of the first clamping bracket 2 and the second clamping bracket 14, one end of the positioning rod 21 is slidably installed in the positioning block 24, and a shift block 23 is provided on the surface of the positioning rod 21, and a second compression spring 22 is provided between the shift block 23 and the positioning block 24.

[0064] In this embodiment, two sets of spline shafts 5 are inserted into the spline sleeves 20 to realize the rapid installation of the speaker edge limit plate 3. However, in order to ensure that the speaker edge limit plate 3 in the first clamping bracket 2 and the second clamping bracket 14 clamps the speaker edge, a quick disassembly assembly is provided to facilitate the replacement of the speaker edge limit plate 3.

[0065] Specifically, when disassembling, pull the shift block 23 to compress the second compression spring 22, so that the positioning rod 21 is separated from the spline shaft 5 and the spline sleeve 20, and the speaker edge limit plate 3 is removed. When installing, perform the same operation as above. After the installation is completed, loosen the positioning rod 21 and insert it into the spline shaft 5 and the spline sleeve 20.

[0066] Embodiment three:

[0067] Based on Example 1, the speaker to be processed is clamped and fixed by using an elastically connected suction cup 6, and the speaker is fixed in the horizontal direction by using the edge limit plate 3 with a limit groove 4. However, in the process of processing the speaker, the forces generated by different processing methods are dispersed and the direction is not fixed. Therefore, this embodiment provides a clamping force in the vertical direction for the speaker. Specifically, a support plate 29 is provided on the protective cover 28, and two groups of lifting components are symmetrically provided at the bottom of the support plate 29. The lifting component includes a cylinder 30. Two groups of ear plates 31 are provided on both sides of the protective cover 28. The two groups of ear plates 31 are pinned with a top arm 32. One end of the top arm 32 is pinned with a sliding top plate 33. The sliding top plate 33 is slidably installed on the bottom of the support plate 29, and the other end of the top arm 32 is pinned to the telescopic rod end of the cylinder 30.

[0068] In this embodiment, a processing base 1 set of support plates 29 is set below the placement position of the speaker to be processed. At the same time, in order to ensure the fixed lifting force applied by the support plate 29 in the vertical direction, a cylinder 30 is symmetrically arranged below the support plate 29. The telescopic rod end of the cylinder 30 is pinned to one end of the top arm 32. At the same time, the other end of the top arm 32 is pinned to a sliding top plate 33, and the sliding top plate 33 is slidably connected to the support plate 29. Therefore, when the cylinder 30 is started, the cylinder 30 pushes the top arm 32 to rotate at the pin shaft between the two sets of ear plates 31, and the sliding top plate 33 is lifted up, completing the lifting force of the support plate 29 on the speaker, effectively avoiding the displacement of the speaker caused by the processing force, further fixing the speaker, and ensuring the stability of the speaker processing.

[0069] Embodiment 4:

[0070] Based on the third embodiment, due to the appearance of the horn, one side has a large opening and the other side has a small opening. Therefore, the debris generated after processing may accumulate in the horn. Therefore, this embodiment adds a set of suction components to clean it.

[0071] A dust box 41 is provided at the bottom of the processing base 1. The dust box 41 is connected to a suction pipe rack 38 through two sets of suction pipes 35. The suction pipe rack 38 is connected to a wind nozzle 40 through a branch pipe 39. The wind nozzle 40 extends to the inside of the horn to clean and collect the debris dropped in the horn after processing.

[0072] It should be noted that an air suction fan is connected to the outside of the dust box 41 .

[0073] Embodiment five:

[0074] Based on the fourth embodiment, in order to facilitate the placement of a larger-sized speaker between the first clamping bracket 2 and the second clamping bracket 14, the suction pipe rack 38 and the related suction structure are set as a mobile structure. Specifically, the suction pipe rack 38 is moved above the processing base 1 through a sliding assembly. The sliding assembly includes a second electric slide 34. The suction pipe 35 is connected to the slider of the second electric slide 34 through a support. A traction shaft 37 is connected to one side of the suction pipe rack 38, and one end of the traction shaft 37 is connected to the top of the first clamping bracket 2 through a second linear guide rail 36. A through groove for the suction pipe 35 to slide is opened in the dust box 41, and an accordion plate 42 is installed in the through groove.

[0075] Since the dust box 41 is fixed, if the suction pipe frame 38 is to be moved, in this embodiment, a second electric slide 34 and a second linear guide rail 36 are respectively provided at one end of the suction pipe 35 and the suction pipe frame 38, so that the suction device can be moved;

[0076] However, during the movement of the suction pipe 35, it is also necessary to maintain communication with the dust box 41. Therefore, a through groove is opened in the dust box 41 at the suction pipe 35. In order to ensure that the air volume does not leak at the same time, it can be sealed with an accordion plate 42.

[0077] Working principle: When the device is in use:

[0078] First, the distance between the first clamping bracket 2 and the second clamping bracket 14 is pulled to be sufficient to place the speaker on the processing base 1. After the speaker is placed between the first clamping bracket 2 and the second clamping bracket 14, the second clamping bracket 14 is moved so that the first clamping bracket 2 and the second clamping bracket 14 clamp and fix the speaker. When the first clamping bracket 2 and the second clamping bracket 14 are close to the speaker, each group of suction cups 6 can be completely attached to the outer wall of the speaker according to the shape of the outer wall of the speaker through the elastic connection of the first compression spring 7, thereby increasing the contact area between the clamping assembly and the speaker, ensuring the clamping strength of the clamping assembly, and thus making the fixing structure stability of the clamping assembly to the speaker;

[0079] At the same time, since the speaker edge limiting plates 3 are fixedly installed on the opposite sides of the first clamping bracket 2 and the second clamping bracket 14, and the speaker edge limiting plates 3 are provided with limiting grooves 4, when the first clamping bracket 2 and the second clamping bracket 14 fix the speaker, the edge of the speaker falls into the two groups of limiting grooves 4, and the speaker is clamped and fixed in cooperation with the clamping assembly;

[0080] After the speaker is placed, the cylinder 30 is started, and the cylinder 30 pushes the top arm 32 to rotate at the pin-jointed shaft between the two sets of ear plates 31, and the sliding top plate 33 is lifted up, so that the lifting force of the support plate 29 on the speaker is completed, which effectively avoids the displacement of the speaker caused by the processing force, further fixes the speaker, and ensures the stability of the speaker processing;

[0081] After the processing is completed, the suction fan connected to the outer side of the dust box 41 is started, and the debris remaining after the processing is adsorbed into the dust box 41 through the air nozzle 40, the branch pipe 39, the suction pipe rack 38 and the suction pipe 35 in sequence, and is cleaned and collected.

[0082] It should be noted that the lifting motor 12, the first linear guide 26, the second electric slide 34, and the cylinder 30 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to technical personnel in this field, so they will not be described in detail.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
