Description

Technical Field

[0001] The utility model relates to the technical field of white film bonding for castings, in particular to an auxiliary white film bonding device for a clutch casting of agricultural machinery. Background Technique

[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. To protect the clutch from dust and stains, the clutch is usually coated with a film. The clutch with a white film attached can reduce the occurrence of failures and extend its service life.

[0003] When bonding the white film, it is necessary to first measure the length and width of the white film of the clutch to be bonded. After the measurement is completed, marks are made for cutting. When bonding, the adhesive is evenly applied to the clutch first, and then the white film is attached. Subsequently, after defoaming with a squeegee, the film coating work of the clutch can be completed.

[0004] The above processes of measurement, cutting, and adhesive application are all very delicate. To maintain the quality and safety of bonding, it is necessary to operate under the guidance of professionals, which requires professional technical training. Moreover, during the film bonding operation, the quality of the film is directly affected by the operation of the bonding personnel. Therefore, there will be differences between the clutches after film bonding, resulting in uneven product quality. Content of the Utility Model

Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0028] The special term "exemplary" here means "serving as an example, an embodiment or an illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments.

[0029] In addition, for better illustration of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0030] Please refer to Figures 1 - 7 , in the embodiment of the present utility model, an auxiliary bonding device for the white film of a farm machinery clutch casting includes:

[0031] A machine tool 1, on which a supporting plate 4 is fixedly arranged, and a placement chamber is formed inside the machine tool 1. A bidirectional moving structure is arranged inside the placement chamber. When the bidirectional moving structure acts, it can drive two groups of clamping members symmetrically arranged along the length direction of the machine tool 1 to approach or separate from each other, so as to clamp or release the casting body 2 placed on the supporting plate 4. When the two groups of clamping members approach each other, the glue-applying member arranged on the machine tool 1 will move towards the supporting plate 4 along the width direction of the machine tool 1;

[0032] Specifically, please refer to Figure 4, a placement groove 401 is formed on the above-mentioned supporting plate 4. The placement groove 401 is a smooth arc-shaped groove inclined towards the center of the supporting plate 4. When placing the cylindrical clutch casting body 2 on the supporting plate 4, the casting body 2 will be guided by the placement groove 401 and be located at the center of the supporting plate 4, positioning and guiding it, so as to facilitate the subsequent clamping member to clamp the casting body 2.

[0033] The bidirectional movement structure includes a bidirectional lead screw 8 rotatably installed in the placement chamber. Two groups of threaded sleeves 9 threadedly connected to the bidirectional lead screw 8 are symmetrically arranged on the bidirectional lead screw 8. A connecting member 901 is fixedly arranged on each group of threaded sleeves 9. One end of the connecting member 901 away from the threaded sleeve 9 is rotatably connected to the clamping member;

[0034] Preferably, please refer to Figure 1 , Figure 2 , Figure 4 , the above two groups of connecting members 901 penetrate through the machine tool 1 and are located in the moving groove 101 opened on the machine tool 1. With the cooperation between the moving groove 101 and the connecting member 901, when the bidirectional lead screw 8 rotates continuously in the same direction, it can drive the two groups of threaded sleeves 9 to drive the two groups of clamping members to approach or move away from each other along the axial direction of the bidirectional lead screw 8, so as to clamp or release the casting body 2 on the supporting plate 4.

[0035] The clamping member includes a clamping block 6. A fixed sleeve 601 is arranged on one side of the clamping block 6 away from the supporting plate 4. The fixed sleeve 601 is slidably connected to a rotating member rotatably installed on the machine tool 1;

[0036] Preferably, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , the above clamping block 6 is arranged in a "conical frustum" structure, as shown in Figure 3 , Figure 6 . A circle of silicone adhesion layer is arranged on the conical frustum side. The silicone adhesion layer has a certain toughness. In particular, after the casting body 2 is placed on the supporting plate 4, the axis of the casting body 2 will be coaxial with the axis of the clamping block 6. Subsequently, when the two groups of clamping blocks 6 approach each other following the two groups of threaded sleeves 9, the clamping block 6 will slowly contact the barrel wall of the casting body 2 until the threaded sleeve 9 moves to the end of the stroke of the bidirectional lead screw 8. The two groups of clamping blocks 6 will fixedly clamp both ends of the casting body 2 with the cooperation of the silicone adhesion layer. At this time, the silicone adhesion layer can increase the friction between the clamping block 6 and the casting body 2, so that the casting body 2 can rotate synchronously with the clamping block 6.

[0037] The rotating member includes a rotating rod 5 rotatably mounted on the machine tool 1, and one end of the rotating rod 5 away from the machine tool 1 is inserted into an insertion groove 602 formed in the fixed sleeve 601;

[0038] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , one end of the rotating rod 5 inserted into the fixed sleeve 601 is arranged in a "cross" structure, and the insertion groove 602 is adapted to the "cross" structure, so that the fixed sleeve 601 can only slide relative to the rotating rod 5, so that when the rotating rod 5 rotates later, it can drive the fixed sleeve 601 and the clamping block 6 to rotate, thereby driving the casting body 2 clamped between the two clamping blocks 6 to rotate, and then facilitating the subsequent white film bonding work.

[0039] Furthermore, the glue attaching member includes a moving block 3 slidably arranged on the machine tool 1. On one side of the moving block 3 immersed in the placement chamber, two groups of guide plates 10 are symmetrically and fixedly arranged along its length direction. An inclined groove 1001 is formed in the guide plate 10, and a protruding column 902 fixedly connected to the connecting member 901 is slidably arranged in the inclined groove 1001;

[0040] Specifically, please refer to Figure 5 , the above-mentioned moving block 3 is slidably arranged in a through groove 102 formed in the machine tool 1. Due to the limitation of the through groove 102, the moving block 3 can only slide along the width direction of the machine tool 1. Moreover, a cavity for storing the adhesive is arranged in the moving block 3. In particular, a glue applying member 301 is arranged on one side of the moving block 3 facing the supporting plate 4. Exemplarily, the glue applying member 301 is selected as a cotton glue strip with adsorbability or water permeability, so as to precipitate the adhesive in the cavity for subsequent application to the side wall of the casting body 2;

[0041] Combined with the above, in the initial state, the above-mentioned protruding column 902 is located on the side of the inclined groove 1001 close to the supporting plate 4. At this time, the moving block 3 is far away from the supporting plate 4. When the two threaded sleeves 9 approach each other, the contact extrusion generated between the protruding column 902 and the groove wall of the inclined groove 1001 will force the guide plate 10 to drive the moving block 3 to approach the supporting plate 4 until the two threaded sleeves 9 move to the forming ends of the bidirectional lead screw 8 to clamp the casting body 2. Then, when the glue applying member 301 on the moving block 3 is attached to the side wall of the casting body 2, and then when the clamping block 6 drives the casting body 2 to rotate, the adhesive will be evenly applied to the outer wall of the casting body 2 by the glue applying member 301, thus facilitating the subsequent film sticking process.

[0042] Furthermore, please refer to Figure 1 , Figure 2 , Figure 3 ,Figure 7 , an auxiliary bonding device for white film of a clutch casting of agricultural machinery, further comprising: a driving assembly, the driving assembly is arranged in the placing chamber, connecting the bidirectional moving structure and the clamping member, capable of driving the bidirectional moving structure and the clamping member to perform alternating movements, and after the casting body 2 is fixedly clamped, the driving assembly will drive the two clamping members to drive the casting body 2 to rotate, and then with the cooperation of the glue attaching member, the rotating casting body 2 can wind the white film arranged on the machine tool 1;

[0043] The driving assembly includes a Maltese cross mechanism, a first linkage structure and a second linkage structure;

[0044] The Maltese cross mechanism includes a driving wheel 11, a first driven wheel 12 and a second driven wheel 14 rotatably installed in the placing chamber;

[0045] Specifically, please refer to Figure 3 、 Figure 7 , there are two sets of the above driving assemblies. As Figure 3 shown, the two driving wheels 11 are coaxially fixedly connected by a connecting rod, and one of the above driving wheels 11 is fixedly connected to the output shaft of the servo motor fixedly installed on the machine tool 1. Specifically, a trigger rod 1101 is fixedly arranged on the side of the driving wheel 11 away from the servo motor. Four groups of grooves are provided on the first driven wheel 12 and the second driven wheel 14 along the circumferential direction. When the driving wheel 11 is driven to rotate one week by the output shaft of the servo motor, the trigger rod 1101 will successively engage with the grooves on the first driven wheel 12 and the second driven wheel 14, and then drive the first driven wheel 12 and the second driven wheel 14 to rotate in the opposite direction to the driving wheel 11 for one-fourth of a week.

[0046] The first linkage structure includes a first transmission wheel 13 coaxially and fixedly connected to the first driven wheel 12, and the first transmission wheel 13 is connected to the bidirectional lead screw 8 through a first transmission belt;

[0047] A second transmission wheel 15 is coaxially and fixedly arranged on the second driven wheel 14, and the second transmission wheel 15 is connected to the rotating rod 5 through a second transmission belt;

[0048] Particularly, the radius of the above first transmission wheel 13 is multiple times the radius of the rotating shaft of the bidirectional lead screw 8, so that during the process of the first transmission wheel 13 following the first driven wheel 12 to rotate one-fourth of a week, it can drive the bidirectional lead screw 8 to rotate multiple circles, thereby driving the two clamping blocks 6 to approach each other to clamp the casting body 2; and the radius of the above second transmission wheel 15 is four times the radius of the rotating rod 5, so that during the process of the second transmission wheel 15 following the second driven wheel 14 to rotate one-fourth of a week, it can drive the rotating rod 5 to rotate one week, thereby driving the casting body 2 to rotate one week for mucosal application;

[0049] In summary, during use, first pull the white film fixed in the film feeding cylinder 7 on the machine tool 1 to overlap on the supporting plate 4, then place the casting body 2 on the supporting plate 4. At this time, the white film is pressed under the casting body 2. Subsequently, start the servo motor, and the output shaft of the servo motor will drive the driving wheel 11 to rotate. Immediately afterwards, the driving wheel 11 will first enter the transmission state with the first driven wheel 12, and then drive the two clamping blocks 6 to clamp the casting body 2. Until the driving wheel 11 and the first driven wheel 12 are disengaged from the transmission state, the clamping blocks 6 will fixedly clamp the casting body 2. During this process, the glue applying part 301 will be attached to the side wall of the casting body 2. After the driving wheel 11 and the second driven wheel 14 enter the transmission state, the rotating rod 5 will drive the clamping blocks 6 and the casting body 2 to rotate one week. During this process, the glue applying part 301 will apply the adhesive to the casting body 2. And when rotating, the casting body 2 with the adhesive attached will adhere the white film to the side wall of the casting body 2, thus completing the film covering operation of the casting body 2. The operation is simple, without the need for professional guidance and training, the film sticking efficiency is high, and the quality of the products produced is consistent;

[0050] After the bonding is completed, the cutting device (not shown in the figure) provided on the machine tool 1 will cut the white film. After the casting body 2 with the white film pasted is taken off, the servo motor rotates in reverse, driving the clamping part and the glue attaching part back to the initial position, and then the film covering operation of the next group of casting bodies 2 can be carried out.
