Description

Technical Field

[0001] The utility model relates to the technical field of bicycle processing, and particularly relates to a bicycle frame spraying device. Background Art

[0002] As the skeleton of the whole bicycle, the frame determines and affects the correctness and comfort of the riding posture to the greatest extent. The frame components are the basic structure of the bicycle, and also the skeleton and main body of the bicycle. Other components are directly or indirectly installed on the frame.

[0003] Before the bicycle frame is put into use, it is first necessary to spray the outer surface. For example, a Chinese patent with the publication number CN218078552U discloses an automatic painting tooling for a bicycle frame, which specifically relates to the technical field of bicycle frame processing. It includes a base, one side of the top of the base is fixedly connected with a support frame, the top of the support frame is fixedly connected with a sliding rod, a horizontal threaded rod is arranged below the sliding rod, and the horizontal threaded rod is rotatably connected with the support frame. One end of the horizontal threaded rod is fixedly connected with the output end of the first motor. The outer surface of the sliding rod is inserted into a sliding hole opened at the top of the moving seat, and the outer surface of the horizontal threaded rod is threadedly connected with a horizontal threaded hole opened at the bottom of the moving seat. The bottom end of the moving seat is fixedly connected with an electric telescopic rod. By starting the first motor to work, the horizontal threaded rod is driven to rotate, so that the moving seat moves horizontally. At the same time, the electric telescopic rod also starts to work, continuously extending and retracting, so that the spray head moves vertically while also moving vertically. When one side of the bicycle frame is sprayed, the second motor rotates, driving the driving shaft to rotate, and through the cooperation of the driven shaft, the bicycle frame is turned over, so that the spray head sprays the unsprayed side. This design can achieve the purpose of automatically spraying and automatically turning over the bicycle frame, greatly reducing the labor intensity of workers and improving work efficiency at the same time.

[0004] When the above-mentioned prior art sprays and processes the bicycle frame, the bicycle frame is clamped and fixed by the clamping blocks.

Detailed implementation

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, 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 invention.

[0027] A bicycle frame sprayer in an embodiment of the present invention is shown in the accompanying drawings Figures 1 - 5 As shown, it includes a workbench. An installation groove 3 is opened at the top of the workbench 1. A connecting block 32 is slidably connected in the installation groove 3. A spraying assembly is arranged on the top of the workbench 1;

[0028] The top of the connecting block 32 is fixedly connected with a mounting seat 4. One side outer wall of the mounting seat 4 close to the spraying assembly is fixedly connected with a fixing plate 42 through an elastic member. One side outer wall of the fixing plate 42 away from the mounting seat 4 is fixedly connected with a connecting pipe 421. The connecting pipe 421 penetrates through the fixing plate 42. A plurality of groups of notches 422 are opened on the outer wall of the connecting pipe 421. An extrusion block 423 is slidably connected in each notch 422. One side outer wall of each extrusion block 423 away from the notch 422 is fixedly connected with a mounting plate 424. One side outer wall of the mounting seat 4 close to the fixing plate 42 is fixedly connected with a conical block 43. The conical block 43 corresponds to the connecting pipe 421. A driving assembly is arranged in the installation groove 3;

[0029] When spraying the bicycle frame, first place the frame vertically on the top of the workbench 1. At this time, the front fork of the bicycle frame contacts the top of the workbench 1. Then move the bicycle frame so that the bottom bracket hole for installing the bottom bracket in the bicycle frame moves to one side of the connecting pipe 421. Subsequently, drive the connecting block 32 to move towards the bicycle frame through the driving assembly. During the movement of the connecting block 32, the connecting pipe 421 will first enter the bottom bracket hole of the frame. As the connecting block 32 continues to move, the fixing plate 42 on the outer wall of the connecting pipe 421 will contact the outer wall of the bottom bracket hole of the frame. At this time, the outer side of the bottom bracket hole of the frame will limit the fixing plate 42. On this premise, when the connecting block 32 moves subsequently, it will drive the conical block 43 to move towards the inside of the connecting pipe 421. During the movement of the conical block 43, its outer wall will contact the side walls of multiple mounting plates 424. As the conical block 43 continues to move, it will squeeze the mounting plates 424, causing multiple extrusion blocks 423 to move outwards from the notch 422 simultaneously and contact the inner wall of the bottom bracket hole of the frame. By setting it like this, under the action of multiple extrusion blocks 423, the position of the bottom bracket hole can be fixed, thereby realizing the fixation of the bicycle frame. And the extrusion blocks 423 for fixing the bicycle frame are located inside the bottom bracket hole of the frame and will not block the outer surface of the frame, thus avoiding the situation where a part of the position cannot be sprayed due to blocking the frame during the spraying operation, and further improving the overall spraying effect of the frame.

[0030] Please refer to the attached drawings Figure 4 、 5 As shown, the elastic member includes multiple first springs 41 fixedly connected between the fixing plate 42 and the mounting seat 4. Both ends of the outer wall of one side of multiple mounting plates 424 close to the notch 422 are fixedly connected with second springs 425. The end of the second spring 425 away from the mounting plate 424 is fixedly connected with the inner wall of the connecting pipe 421. A limiting block 5 is fixedly connected to the top of the workbench 1 and on one side of the mounting groove 3. A circular hole 51 is opened on the outer wall of the limiting block 5;

[0031] When spraying the frame, first place the side wall of the middle shaft hole of the frame away from the connecting pipe 421 against the limiting block 5 to prevent the frame from being pushed during the extrusion of the mounting plate 424 by the conical block 43, so as to ensure that the extrusion block 423 can have a good contact effect with the middle shaft hole of the frame. During the extrusion of the mounting plate 424 by the conical block 43, the distance between the fixed plate 42 and the connecting seat is reduced, thereby compressing the first spring 41. Under the action of the first spring 41, the fixed plate 42 is closely attached to the side wall of the middle shaft hole of the frame. During the movement of the mounting plate 424, the second spring 425 is compressed. When a spraying operation is completed, the driving assembly drives the connecting seat away from the frame. During this process, since the fixed plate 42 is closely attached to the side wall of the middle shaft hole of the frame under the action of the first spring 41, when the connecting seat moves, the fixed plate 42 remains in a state of being attached to the side wall of the middle shaft hole of the frame, and the conical block 43 moves out of the connecting pipe 421 as the connecting seat moves. As the conical block 43 moves out, the conical block 43 no longer limits the mounting plate 424. At this time, the mounting plate 424 will reset under the action of the elastic restoring force of the second spring 425 itself, thereby driving the extrusion block 423 to return to the notch 422 and releasing the fixation of the frame, facilitating the subsequent use of the extrusion block 423 and facilitating the staff to take out the sprayed frame.

[0032] Please refer to the attached drawings Figure 4 、 5 As shown, a plurality of through holes are formed in the outer wall of the mounting seat 4, and the through holes are perpendicular to the fixed plate 42. A plurality of positioning rods 44 are fixedly connected to the outer wall of the fixed plate 42 close to the mounting seat 4. The positioning rods 44 correspond to the through holes one by one, and the positioning rods 44 are slidably installed in the through holes. A positioning block 45 is fixedly connected to each end of the positioning rod 44 away from the fixed plate 42;

[0033] When the fixed plate 42 is limited by the side wall of the middle shaft hole of the frame, at this time, the connecting seat moves towards the fixed plate 42 as the connecting block 32 moves. During this process, the positioning rod 44 moves in the through hole. At this time, the positioning rod 44 can limit the fixed plate 42 to prevent the fixed plate 42 from tilting due to the increase in the elastic force of the first spring 41 when the connecting seat moves towards the fixed plate 42, so as to ensure that the conical block 43 can enter the connecting pipe 421 and squeeze the side walls of the plurality of mounting plates 424, thereby ensuring the normal progress of the spraying operation.

[0034] Please refer to the attached drawings Figure 2 、 3As shown, the driving component includes a second lead screw 31 rotatably connected in the installation groove 3. A connecting block 32 is threadedly connected to the outside of the second lead screw 31. The outer wall of the workbench 1 is fixedly connected with a second motor 35, and the output shaft of the second motor 35 is fixedly connected to the second lead screw 31;

[0035] When spraying operations are carried out, first turn on the second motor 35. The output shaft of the second motor 35 will drive the second lead screw 31 to rotate. The rotating second lead screw 31 can drive the connecting block 32 to move in the installation groove 3 through screw transmission, thus ensuring the normal progress of the spraying operation.

[0036] Please refer to the attached drawings Figure 2 、 3 As shown, two sets of sliding grooves 33 are opened in the workbench 1 and located inside the installation groove 3. Two sets of sliding blocks 34 are fixedly connected to the outer wall of the connecting block 32. The sliding blocks 34 correspond to the sliding grooves 33. The sliding blocks 34 are slidably installed in the sliding grooves 33, and the sliding blocks 34 are adapted to the sliding grooves 33 in size;

[0037] When the connecting block 32 moves, it will drive the sliding blocks 34 to move in the sliding grooves 33. Since the sliding blocks 34 are adapted to the sliding grooves 33 in size, the sliding blocks 34 can play a limiting role on the connecting block 32, avoiding the situation that the connecting block 32 rotates synchronously with the second lead screw 31 during the rotation of the second lead screw 31 due to excessive friction between the connecting block 32 and the second lead screw 31, thus ensuring that the connecting block 32 can move stably in the installation groove 3 and ensuring the normal development of the spraying operation.

[0038] Please refer to the attached drawings Figure 1 、 2 As shown, the spraying component includes two sets of support plates 2 fixedly connected to the top of the workbench 1. A first lead screw 21 is rotatably connected between the two sets of support plates 2. A moving block 24 is threadedly connected to the outer wall of the first lead screw 21. One side outer wall of the moving block 24 close to the installation groove 3 is fixedly connected with a connecting rod 25. Two sets of installation pipes 26 are fixedly connected to the bottom of the connecting rod 25. Spray nozzles 27 are fixedly connected to the facing surfaces of the two sets of installation pipes 26. A first motor 23 is fixedly connected to the outer wall of one of the support plates 2, and the output shaft of the first motor 23 is fixedly connected to the first lead screw 21;

[0039] When the bicycle frame is fixed, the spray nozzles 27 can be turned on for spraying, and at the same time, the first motor 23 is turned on. The output shaft of the first motor 23 will drive the first lead screw 21 to rotate. The rotating first lead screw 21 drives the moving block 24 to move horizontally through screw transmission, thereby driving the two sets of spray nozzles 27 to move horizontally, realizing the spraying of the bicycle frame, which is convenient and fast.

[0040] Please refer to the attached drawings Figure 1 、2 As shown, a limiting rod 22 is fixedly connected between the two groups of support plates 2, and the limiting rod 22 penetrates through the moving block 24;

[0041] During the spraying operation, since the limiting rod 22 penetrates through the moving block 24, when the moving block 24 moves, the limiting rod 22 will limit its position, avoiding the situation that the first lead screw 21 drives it to rotate synchronously when rotating due to the excessive friction between the moving block 24 and the first lead screw 21, so as to ensure that the positions of the two groups of nozzles 27 do not shift and ensure the normal progress of the spraying operation.

[0042] Working principle: When spraying the bicycle frame, first place the frame vertically on the top of the workbench 1. At this time, the front fork of the bicycle frame contacts the top of the workbench 1. Then move the bicycle frame so that the bottom bracket hole for installing the bottom bracket in the bicycle frame moves to one side of the connecting pipe 421. Then turn on the second motor 35. The output shaft of the second motor 35 will drive the second lead screw 31 to rotate. The rotating second lead screw 31 can drive the connecting block 32 to move towards the bicycle frame in the installation groove 3 through screw transmission. During the movement of the connecting block 32, the connecting pipe 421 will first enter the bottom bracket hole of the frame. As the connecting block 32 continues to move, the fixing plate 42 on the outer wall of the connecting pipe 421 will contact the outer wall of the bottom bracket hole of the frame. At this time, the outside of the bottom bracket hole of the frame will limit the fixing plate 42. On this premise, when the connecting block 32 moves subsequently, it will drive the conical block 43 to move towards the inside of the connecting pipe 421. During the movement of the conical block 43, its outer wall will contact the side walls of multiple mounting plates 424. As the conical block 43 continues to move, it will squeeze the mounting plates 424, causing multiple extrusion blocks 423 to move outwards from the notch 422 at the same time and contact the inner wall of the bottom bracket hole of the frame. Through such a setting, under the action of multiple extrusion blocks 423, the position of the bottom bracket hole can be fixed, thereby realizing the fixation of the bicycle frame. Moreover, the extrusion blocks 423 used to fix the bicycle frame are located inside the bottom bracket hole of the frame and will not block the outer surface of the frame, thus avoiding the situation that part of the position cannot be sprayed due to blocking the frame during the spraying operation, and further improving the overall spraying effect of the frame;

[0043] When a spraying operation is completed, the driving component will drive the connecting seat away from the vehicle frame. During this process, since the fixing plate 42 is closely attached to the side wall of the central axis hole of the vehicle frame under the action of the first spring 41, when the connecting seat moves, the fixing plate 42 remains in a state of being attached to the side wall of the central axis hole of the vehicle frame, and the conical block 43 will move out of the inner part of the connecting pipe 421 along with the movement of the connecting seat. As the conical block 43 moves out, the conical block 43 no longer limits the mounting plate 424. At this time, the mounting plate 424 will reset under the action of the elastic restoring force of the second spring 425, thereby driving the extrusion block 423 to return to the notch 422 again and releasing the fixation of the vehicle frame, facilitating the subsequent use of the extrusion block 423 and facilitating the staff to take out the vehicle frame after spraying is completed.

[0044] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
