Description

Technical Field

[0001] This application belongs to the field of polishing cloth wheel production technology, and particularly relates to an adhesive device. Background Technology

[0002] In the production process of polishing cloth wheels, one of the key steps is to bond and fix the pre-formed cylindrical cloth wheel (composed of a wood core and multiple layers of cloth) to a circular wooden board. This bonding process directly affects the overall strength, dynamic balance performance, and subsequent machining accuracy of the mounting holes of the cloth wheel product.

[0003] Currently, most bonding processes involve operators manually aligning the glued circular wooden board with the end face of the precast body and applying vertical pressure using simple clamps or weights. However, manual alignment makes it difficult to ensure the alignment of the central axis of the circular wooden board with the cylindrical axis of the precast body, which may lead to the product being off-center after bonding. Furthermore, manual alignment and pressing are inefficient and not conducive to improving the production efficiency of polishing cloth wheels. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides an adhesive device that can effectively ensure accurate adhesion and improve the production efficiency of polishing cloth wheels.

[0005] To achieve the above objectives, the present invention employs the following technology: An adhesive device for bonding a circular wooden board to a fabric wheel preform, comprising: The mounting block is moved vertically and has a horizontally arranged rotating shaft on one side. The rotating shaft rotates around its own axis as the mounting block moves, and the direction of rotation corresponds to the lifting and lowering of the mounting block. The mounting frame is connected to the rotating shaft on one side; the mounting frame is equipped with a clamping assembly for clamping the round wooden board; when the round wooden board is clamped, the axis of the rotating shaft is arranged radially along the round wooden board. The positioning mechanism, located between the rotating shaft and the mounting block, is used to position the circular wooden board in the clamped state to a horizontal position. A placement platform, located below the mounting frame and movable vertically, is used to horizontally place the precast fabric wheel body. The drive assembly, located on the other side of the mounting block, is used to drive the mounting block to move and to cooperate with the positioning mechanism to fix the circular wooden board in the clamped state to a horizontal state; the drive assembly is also used to drive the placement platform to move upward.

[0006] The beneficial effects of this utility model are as follows: By meshing gears and racks, the vertical movement of the mounting block is converted into the rotation of the mounting frame. Combined with the clamping assembly, stable rotation of the circular wooden board can be achieved. Simultaneously, through the positioning mechanism, connecting plate, and movable plate, along with the helical spring and second linear mechanism, the mounting frame can be effectively fixed after rotating 180°. Furthermore, through the cooperation of the movable plate and the reversing mechanism, the cloth wheel prefabricated body on the placement platform is stably bonded to the circular wooden board. The entire bonding process has a high degree of automation, the combination efficiency of the cloth wheel prefabricated body and the circular wooden board is high, and the coincidence of the central axis of the circular wooden board and the cylindrical axis of the prefabricated body can be effectively guaranteed.

Detailed Implementation

[0011] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0012] This application provides an adhesive device, such as... Figures 1-3 As shown, it includes: mounting block 1, mounting frame 2, positioning mechanism 3, placement platform 4, drive component 5, etc.

[0013] like Figure 1 and Figure 2As shown, the mounting block 1 is slidably fitted onto a vertically arranged guide post 12, and a horizontally arranged rotating shaft 11 is provided on one side of the guide post 12. The rotating shaft 11 is rotatable around its own axis, and the far end of the rotating shaft 11 is vertically connected to the outside of the mounting frame 2. A vertically arranged rack 16 is fixed on one side of the guide post 12 through a connecting bracket. A gear 17 that meshes with the rack 16 is coaxially provided on the rotating shaft 11 between the mounting frame 2 and the mounting block 1. When the mounting block 1 moves along the guide post 12, the rotating shaft 11 can drive the mounting frame 2 to rotate under the meshing action of the gear 17 and the rack 16.

[0014] like Figure 1 As shown, a horizontally arranged connecting plate 13 is connected to the other side of the mounting block 1, and a movable plate 14 is arranged parallel below it; the connecting plate 13 and the movable plate 14 are connected by a vertically arranged helical spring 15; the driving assembly 5 is used to drive the movable plate 14 to move in the vertical direction.

[0015] like Figure 2 As shown, the mounting frame 2 is provided with a clamping assembly 21. Specifically, the clamping assembly 21 includes two horizontally and oppositely arranged V-shaped plates 22. One V-shaped plate 22 is fixed, and the other V-shaped plate 22 is driven by a first linear mechanism 23 located on the outer side of one end of the mounting frame 2. When the first linear mechanism 23 drives the other V-shaped plate 22 to move toward the fixed V-shaped plate 22 to clamp the circular wooden board, the axis of the rotating shaft 11 is arranged radially along the circular wooden board.

[0016] like Figure 1 and Figure 2 As shown, the positioning mechanism 3 is located between the rotating shaft 11 and the mounting block 1. Specifically, the positioning mechanism 3 includes a positioning rod 31 that is vertically disposed on the shaft of the rotating shaft 11, and its axis is perpendicularly intersecting the axis of the rotating shaft 11. Two positioning blocks 32 are provided on one side of the mounting block 1, which are located on both sides of the rotating shaft 11 respectively. When the positioning rod 31 abuts against the positioning block 32, the circular wooden board in the clamping state is horizontally positioned.

[0017] like Figure 1 As shown, the placement platform 4 is located below the mounting frame 2 and is moved vertically to place the precast fabric wheel horizontally.

[0018] like Figure 1 As shown, the drive assembly 5 includes a second linear mechanism 51 located on the other side of the mounting block 1, with its drive end pointing vertically downward and connected to the movable plate 14; a reversing mechanism 6 is provided below the placement platform 4, which is used to rotate the downward movement of the movable plate 14 into the upward movement of the placement platform 4.

[0019] When applying, such as Figures 1-3As shown, the mounting block 1 is moved up to the mounting frame 2 and rotated to a horizontal position. The clamping assembly 21 is operated to clamp the circular wooden board with glue applied to its top surface. The circular wooden board is in a horizontal position with the glued end facing upwards. The projection of the circular wooden board downwards in the vertical direction coincides with the top surface of the cloth wheel prefabricated body on the placement platform 4. The second linear mechanism 51 drives the movable plate 14 to move downwards. Since the movable plate 14 is connected to the connecting plate 13 by a helical spring 14, and the connecting plate 13 is connected to the mounting block 1, the mounting block 1, the connecting plate 13, and the movable plate 14 will move downwards synchronously. During the downward movement, the mounting frame 2 will rotate around the rotating shaft 11 due to the meshing of the gear 17 and the rack 16, that is, the circular wooden board will rotate. When the circular wooden board rotates 180°, the positioning rod 31 will abut against the... The second linear mechanism 51 continues to drive the movable plate 14 to move downward. Since the positioning rod 31 abuts against the positioning block 32, the rotating shaft 11 can no longer rotate, the connecting plate 13 is fixed, the spiral spring 15 is stretched, and the elasticity of the spiral spring 15 presses the positioning rod 31 tightly against the positioning block 32, thereby fixing the circular wooden board. As the movable plate 14 continues to move downward and acts on the reversing mechanism 6, it converts the downward movement of the movable plate 14 into the upward movement of the placement platform 4, thereby abutting and pressing the top surface of the horizontally placed cloth wheel preform on the placement platform 4 against the glued end face of the circular wooden board, thus realizing the combination of the circular wooden board and the cloth wheel preform. After that, it is only necessary to operate the clamping assembly 21 to release the circular wooden board and take out the circular wooden board and the cloth wheel preform.

[0020] Through the meshing of gear 17 and rack 16, the vertical movement of mounting block 1 is converted into the rotation of mounting frame 2. With the help of clamping assembly 21, stable rotation of the circular wooden board can be achieved. At the same time, through the setting of positioning mechanism 3, connecting plate 13, and movable plate 14, and with the help of helical spring 15 and second linear mechanism 51, mounting frame 2 can be effectively fixed after rotating 180°. In addition, through the cooperation of movable plate 14 and reversing mechanism 6, the cloth wheel prefabricated body on the placement platform 4 is stably bonded to the circular wooden board. The entire bonding process has a high degree of automation, the combination efficiency of cloth wheel prefabricated body and circular wooden board is high, and the coincidence of the central axis of the circular wooden board and the cylindrical axis of the prefabricated body can be effectively guaranteed.

[0021] Specifically, such as Figure 1 As shown, the reversing mechanism 6 includes a lever 61 located below the placement platform 4; the middle of the lever 61 is rotatably mounted on the guide post 12, and its rotation axis is horizontal; one end of the lever 61 is located below the placement platform 4, and the other end is located below the movable plate 14. In application, the movable plate 14 abuts against and presses down the other end of the lever 61, causing one end to tilt up and lift the placement platform 4.

[0022] Preferred, such as Figure 1As shown, a guide structure can be provided at the bottom of the placement platform 4, such as a guide seat perpendicular to the bottom surface of the placement platform 4. A guide rod perpendicular to the bottom surface of the placement platform 4 is slidably passed through the guide seat to ensure the stability of the lifting and lowering of the placement platform 4.

[0023] Specifically, the first linear mechanism 23 and the second linear mechanism 51 can be selected from linear cylinders, hydraulic cylinders, etc.

[0024] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
