Description

Technical Field

[0001] This utility model relates to the field of loudspeaker processing technology, and in particular to a fixing structure for loudspeaker housings used in loudspeaker processing. Background Technology

[0002] A loudspeaker is short for loudspeaker unit, also known simply as a unit or "horn." It is an electroacoustic transducer commonly found in the electroacoustic field. While a relatively weak component in an electroacoustic system, the loudspeaker is also a crucial one. There are many types of loudspeakers, with significant price differences. Audio energy is transmitted through electromagnetic, piezoelectric, or electrostatic effects, causing the cone or diaphragm to vibrate and create sound. During loudspeaker manufacturing, the housing often needs to be fixed in place.

[0003] Existing speaker manufacturing fixtures can only fix speaker housings of one size, thus limiting their application and practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixing structure for speaker housings used in speaker manufacturing. This overcomes the deficiencies of existing technologies and effectively solves the problem that existing fixing structures can only fix speaker housings of one size, thus limiting their application range and practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixing structure for a speaker housing used in speaker manufacturing includes a base. A support plate is welded and fixed to one top end of the base, and a clamping plate is rotatably connected to one side of the support plate. A fixing shell is welded and fixed to the top of the support plate, and lead screws are rotatably connected to the inner walls of both ends of the fixing shell. A movable plate is screwed to the wall of the lead screw, and a clamping mechanism is welded and fixed to the outer wall of one side of the movable plate. The clamping mechanism includes a circular block, a connecting frame welded and fixed at equal intervals to the annular outer wall of the circular block, a handle screw rotatably connected to the inner walls of both ends of the connecting frame, a movable block screwed to the wall of the handle screw, and a protruding rod rotatably connected to the outer wall of one side of the movable block.

[0007] By abutting the smaller diameter end of the speaker housing against the clamping plate, the second servo motor drives the lead screw to rotate. The rotating lead screw moves the movable plate along the fixed shell, adjusting the distance between the clamping mechanism and the clamping plate to accommodate speaker housings of different lengths. The speaker housing is clamped between the clamping plate and the clamping mechanism. By rotating the handle screw, the position of the movable block within the connecting frame is adjusted. When it is necessary to work on the conical outer wall of the speaker housing, the position of the movable block is adjusted so that the protrusion abuts against the conical inner wall of the speaker housing. When it is necessary to work on the conical inner wall of the speaker housing, the position of the movable block is adjusted so that the protrusion abuts against the conical outer wall of the speaker housing. In conjunction with the first servo motor driving the rotating shaft to rotate, the rotating shaft drives the clamping plate to rotate, thereby enabling the speaker housing clamped between the clamping plate and the clamping mechanism to rotate, facilitating painting or polishing operations on the inner or outer wall of the speaker housing.

[0008] Preferably, a rotating shaft is welded and fixed to the outer wall of the clamping disc near the support plate, and the rotating shaft is rotatably connected to the support plate. The outer wall of the other side of the clamping disc is engraved with ring patterns whose inner diameter decreases at equal intervals.

[0009] The clamp is rotatably connected to one side of the support plate via a rotating shaft, and the ring pattern allows the small-diameter end of the speaker housing to abut against the clamp.

[0010] Preferably, a first servo motor is installed and fixed on one side of the outer wall of the support plate, and the output shaft of the first servo motor is connected and fixed to one end of the rotating shaft through a coupling.

[0011] The first servo motor drives the rotating shaft to rotate, and the rotating shaft drives the clamping plate to rotate, thereby enabling the speaker housing clamped between the clamping plate and the clamping mechanism to rotate.

[0012] Preferably, a second servo motor is fixedly mounted on the outer wall of one end of the fixed housing, and the output shaft of the second servo motor is connected and fixed to one end of the lead screw through a coupling, and the fixed housing and the movable plate form a sliding fit.

[0013] The second servo motor drives the lead screw to rotate, and the rotating lead screw drives the movable plate to move along the fixed shell, which can adjust the distance between the clamping mechanism and the clamping plate, thus adapting to speaker shells of different lengths.

[0014] Preferably, a fixing rod is welded and fixed to the outer wall of the circular block near the movable plate, and one end of the fixing rod is welded and fixed to the movable plate.

[0015] The clamping mechanism is connected and fixed to the movable plate via a fixed rod.

[0016] Preferably, the movable block and the connecting frame are in a sliding fit, and a washer is fitted and fixed to one end of the protruding rod wall near the movable block.

[0017] The included gaskets ensure that one end of the speaker housing can rotate without obstructing the clamping mechanism when it comes into contact with it.

[0018] The beneficial effects of this utility model are as follows:

[0019] By abutting the smaller diameter end of the speaker housing against the clamping plate, and then adjusting the distance between the clamping mechanism and the clamping plate by rotating the lead screw, speaker housings of different lengths can be adapted. The speaker housing is clamped between the clamping plate and the clamping mechanism. By rotating the handle screw, the position of the movable block in the connecting frame is adjusted. When it is necessary to work on the conical outer wall of the speaker housing, the position of the movable block is adjusted so that the protrusion abuts against the conical inner wall of the speaker housing. When it is necessary to work on the conical inner wall of the speaker housing, the position of the movable block is adjusted so that the protrusion abuts against the conical outer wall of the speaker housing. This effectively solves the problem that the existing fixed structure can only fix speaker housings of one size, thus limiting its application range and practicality. Attached Figure Description

[0026] Reference Figure 1-3A fixing structure for a speaker housing in speaker processing includes a base 1, a support plate 2 welded to one end of the top of the base 1, a clamping plate 3 rotatably connected to one side of the support plate 2, a fixing shell 5 welded to the top of the support plate 2, a lead screw 7 rotatably connected to the inner walls of both ends of the fixing shell 5, a movable plate 8 screwed to the rod wall of the lead screw 7, and a clamping mechanism 9 welded to the outer wall of one side of the movable plate 8. The clamping mechanism 9 includes a circular block 10, a connecting frame 12 welded at equal intervals to the annular outer wall of the circular block 10, a handle screw 13 rotatably connected to the inner walls of both ends of the connecting frame 12, a movable block 14 screwed to the rod wall of the handle screw 13, and a protruding rod 15 rotatably connected to the outer wall of one side of the movable block 14.

[0027] A rotating shaft is welded and fixed to the outer wall of the clamping plate 3 near the support plate 2. The rotating shaft is rotatably connected to the support plate 2. The outer wall of the other side of the clamping plate 3 is engraved with rings with an inner diameter decreasing at equal intervals. The clamping plate 3 is rotatably connected to one side of the support plate 2 through the rotating shaft. The rings facilitate the contact between the small-diameter end of the speaker housing and the clamping plate 3. A first servo motor 4 is installed and fixed to one side of the outer wall of the support plate 2. The output shaft of the first servo motor 4 is connected and fixed to one end of the rotating shaft through a coupling. The first servo motor 4 drives the rotating shaft to rotate. The rotating shaft drives the clamping plate 3 to rotate, thereby enabling the speaker housing clamped between the clamping plate 3 and the clamping mechanism 9 to rotate.

[0028] A second servo motor 6 is fixedly mounted on the outer wall of one end of the fixed shell 5. The output shaft of the second servo motor 6 is connected and fixed to one end of the lead screw 7 through a coupling. The fixed shell 5 and the movable plate 8 form a sliding fit. The second servo motor 6 drives the lead screw 7 to rotate. The rotating lead screw 7 drives the movable plate 8 to move along the fixed shell 5, which can adjust the distance between the clamping mechanism 9 and the clamping plate 3, thereby adapting to speaker shells of different lengths. A fixing rod 11 is welded and fixed to the outer wall of the round block 10 near the movable plate 8. One end of the fixing rod 11 is welded and fixed to the movable plate 8. The clamping mechanism 9 is connected and fixed to the movable plate 8 through the fixing rod 11. The movable block 14 and the connecting frame 12 form a sliding fit. A washer is sleeved and fixed to the end of the protruding rod 15 near the movable block 14. The washer ensures that the rotation of the speaker shell is not hindered when one end of the speaker shell comes into contact with the clamping mechanism 9.

[0029] Working principle:

[0030] During operation, the small-diameter end of the speaker housing abuts against the clamping plate 3, and then the second servo motor 6 drives the lead screw 7 to rotate. The rotating lead screw 7 drives the movable plate 8 to move along the fixed shell 5, adjusting the distance between the clamping mechanism 9 and the clamping plate 3, thereby adapting to speaker housings of different lengths. The speaker housing is clamped between the clamping plate 3 and the clamping mechanism 9. By rotating the handle screw 13, the position of the movable block 14 within the connecting frame 12 is adjusted. When it is necessary to work on the conical outer wall of the speaker housing, the position of the movable block 14 is adjusted so that the protrusion 15 abuts against the conical inner wall of the speaker housing. When it is necessary to work on the conical inner wall of the speaker housing, the position of the movable block 14 is adjusted so that the protrusion 15 abuts against the conical outer wall of the speaker housing. In conjunction with the first servo motor 4 driving the rotating shaft to rotate, the rotating shaft drives the clamping plate 3 to rotate, thereby enabling the speaker housing clamped between the clamping plate 3 and the clamping mechanism 9 to rotate, facilitating painting or polishing of the inner or outer wall of the speaker housing.
