[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. The performance of a loudspeaker has a great impact on the sound quality. A loudspeaker is the weakest component in audio equipment, and it is necessary to apply glue to seal the joints during production.

[0003] According to a glue application machine clamping mechanism disclosed in Chinese Patent Publication No. CN216459867U, which includes a bottom plate, support rods are welded and installed on both side walls of the bottom plate, a glue application mechanism is arranged on the corresponding side walls of the support rods, a second chute is opened at the top of the bottom plate, and a third threaded rod is rotatably installed on the front and rear inner walls of the second chute. This glue application machine clamping mechanism limits the position of the glass plate by setting a movable tooling fixture, so that when the device is performing glue application operations, the glass plate will not shift in position due to the movement state of the glue application machine. At the same time, a rubber pad is arranged on the clamping plate of the tooling fixture of the device, effectively avoiding the glass from cracking or scratching caused by the rigid contact between the clamping plate and the glass, ensuring the quality of the glass plate, and improving the practicability of the device to a certain extent.

[0004] Through the above method, the fixing effect can be achieved, but the outer surface of the loudspeaker is generally conical, so it is inconvenient to fix by using the method of planar clamping. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a glue application machine clamping mechanism, which solves the problem that the outer surface of the loudspeaker is generally conical, so it is inconvenient to fix by using the method of planar clamping.

[0006] To achieve the above object, the utility model is realized through the following technical solutions: A glue application machine clamping mechanism includes a mounting plate, one side of the mounting plate is fixedly connected with a connecting rod, there are two groups of connecting rods arranged symmetrically, a rotating groove is opened on the side of the connecting rod away from the mounting plate, a fixing wheel is rotatably connected inside the rotating groove, a rubber sleeve is sleeved outside the fixing wheel, a rotating shaft is fixedly connected to the top and bottom of the fixing wheel, and the rotating shaft is rotatably connected inside the connecting rod.

[0007] Preferably, a rotating rod is fixedly connected to the top of the rotating shaft, a fixing sleeve is rotatably connected to the outside of the rotating rod, and a limiting component is arranged between the fixing sleeve and the rotating rod.

[0008] Preferably, the limiting component includes a rubber sheet, the rubber sheet is fixedly connected to the outside of the rotating rod, one end of the rubber sheet away from the rotating rod abuts against a positioning block, and the positioning block is fixedly connected to the inside of the fixed sleeve.

[0010] Preferably, a fitting block is fixedly connected to the side of the mounting plate away from the connecting rod. The fitting block is arranged in a "T" shape, and a moving plate is arranged outside the fitting block.

[0011] Preferably, a clamping groove is formed at the position of the moving plate close to the fitting block. The fitting block is fitted inside the clamping groove, and a threaded groove is formed at the position of the moving plate close to the bottom.

[0012] The utility model provides a clamping mechanism for a caulking gun. Compared with the prior art, the following beneficial effects are achieved:

[0013] 1. For this clamping mechanism of the caulking gun, the mounting plate drives the connecting rod to move. The connecting rod squeezes the fixed wheel to rotate through the rotating shaft inside the rotating groove formed in the connecting rod. At this time, the mounting plate moves towards the clamped speaker. The rubber sleeve outside the fixed wheel improves the friction force during the clamping of the speaker, achieving the effect of clamping and fixing the speaker, solving the problem that the clamping is not firm and loose when only using the clamping and fixing method, and improving the fixing effect of clamping the speaker.

[0014] 2. For this clamping mechanism of the caulking gun, the rotation of the rotating rod drives the rotation of the rubber sheet. The structure of the rubber sheet rotates outside the positioning block. The positioning block can limit the rotation direction of the rubber sheet. The fixed sleeve is fixed on the top of the connecting rod, and the moving position of the rubber sheet is limited through the positioning block, achieving the effect of limiting the rotation direction, solving the problem that the speaker becomes loose when only using the rotation method for fixing, and improving the fixing effect of the rotation direction of the fixed wheel.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a clamping mechanism for a caulking machine, including a mounting plate 1, one side of the mounting plate 1 is fixedly connected with a connecting rod 2, there are two groups of connecting rods 2 arranged symmetrically, a rotating groove 3 is opened on the side of the connecting rod 2 away from the mounting plate 1, a fixed wheel 5 is rotatably connected inside the rotating groove 3, a rubber sleeve 6 is sleeved outside the fixed wheel 5, rotating shafts 4 are fixedly connected to the top and bottom of the fixed wheel 5, the rotating shafts 4 are rotatably connected inside the connecting rod 2, a rotating rod 7 is fixedly connected to the top of the rotating shaft 4, a fixed sleeve 10 is rotatably connected outside the rotating rod 7, and a limiting component is arranged between the fixed sleeve 10 and the rotating rod 7.

[0023] During operation, the movement of the mounting plate 1 drives the connecting rod 2 to push the fixed wheel 5 into contact with the speaker, and the rubber sleeve 6 outside the fixed wheel 5 contacts the speaker to increase the friction force, making the rotation of the fixed wheel 5 in the rotating groove 3 smoother. The fixed wheel 5 rotates smoothly in the rotating groove 3 through the rotating shaft 4 inside the connecting rod 2. At this time, the rotating rod 7 rotates inside the fixed sleeve 10, achieving the contact clamping effect of different shapes during fixation, solving the problem of loosening during clamping caused by only using planar clamping, and improving the fixing effect of the speaker.

[0024] The limiting component includes a rubber sheet 8, the rubber sheet 8 is fixedly connected to the outside of the rotating rod 7, one end of the rubber sheet 8 away from the rotating rod 7 abuts against a positioning block 9, the positioning block 9 is fixedly connected to the inside of the fixed sleeve 10, there are multiple groups of rubber sheets 8 and positioning blocks 9 arranged in a circumferential array, the fixed sleeve 10 is fixedly connected to the top of the connecting rod 2, and a connecting component is arranged at the rear end of the mounting plate 1.

[0025] During operation, when the rotating shaft 4 rotates inside the connecting rod 2, the rotating rod 7 controls the rotation of the rubber sheet 8 inside the fixed sleeve 10. The rotation of the rubber sheet 8 rotates outside the positioning block 9 to achieve the effect of single-sided contact rotation. The fixing form of the fixed sleeve 10 can restrict the rotation of the rubber sheet 8 and the positioning block 9, solving the problem that the speaker rotates simultaneously with the fixed wheel 5 due to the previous rotational connection, resulting in the loosening of the speaker, and improving the firmness of fixing the speaker.

[0026] On one side of the mounting plate 1 away from the connecting rod 2, a fitting block 11 is fixedly connected. The fitting block 11 is arranged in a "T" shape. A moving plate 12 is arranged outside the fitting block 11. A clamping groove 13 is formed at the position of the moving plate 12 close to the fitting block 11. The fitting block 11 is fitted inside the clamping groove 13. A threaded groove 14 is formed at the position of the moving plate 12 close to the bottom.

[0027] During operation, by fitting the fitting block 11 inside the clamping groove 13 formed in the moving plate 12, the mounting plate 1 is fixed on one side of the moving plate 12 for subsequent clamping effect. The threaded groove 14 can control the movement of the moving plate 12, so that the device can perform the clamping work, achieving the effect of arbitrarily replacing the mounting plate 1, solving the problem that the fixed structure makes it inconvenient to replace the clamping structure for different parts, and improving the convenience of replacing different clamping structures.

[0028] During operation or use, the movement of the mounting plate 1 drives the connecting rod 2 to push the fixed wheel 5 into contact with the speaker. The rubber sleeve 6 outside the fixed wheel 5 contacts the speaker to increase the friction force, and the fixed wheel 5 rotates more smoothly inside the rotating groove 3. The fixed wheel 5 rotates smoothly inside the rotating groove 3 through the rotating shaft 4 inside the connecting rod 2. At this time, the rotating rod 7 rotates inside the fixed sleeve 10, achieving the contact clamping effect of different shapes during fixation, solving the problem that only planar clamping leads to loosening of the clamping, and improving the fixing effect of the speaker. When the rotating shaft 4 rotates inside the connecting rod 2, the rotating rod 7 controls the rotation of the rubber sheet 8 inside the fixed sleeve 10. The rotation of the rubber sheet 8 rotates outside the positioning block 9 to achieve the effect of single-sided contact rotation. The fixing form of the fixed sleeve 10 can restrict the rotation of the rubber sheet 8 and the positioning block 9, solving the problem that the speaker rotates simultaneously with the fixed wheel 5 due to the previous rotational connection, resulting in the loosening of the speaker, and improving the firmness of fixing the speaker. By fitting the fitting block 11 inside the clamping groove 13 formed in the moving plate 12, the mounting plate 1 is fixed on one side of the moving plate 12 for subsequent clamping effect. The threaded groove 14 can control the movement of the moving plate 12, so that the device can perform the clamping work, achieving the effect of arbitrarily replacing the mounting plate 1, solving the problem that the fixed structure makes it inconvenient to replace the clamping structure for different parts, and improving the convenience of replacing different clamping structures.
