Description

Technical Field

[0001] This utility model relates to pen holder assembly technology, and more particularly to an assembly and tightening device for pen holder production. Background Technology

[0002] When assembling high-end ballpoint pens made of metal, the pen tip needs to be installed onto the pen holder. If this is done manually, it requires a lot of time and effort, leading to a slowdown in production. Therefore, a tightening device that can automatically tighten the pen tip is needed. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes an assembly and tightening device for pen holder production.

[0004] The technical solution of this utility model is implemented as follows:

[0005] An assembly and tightening device for pen holder production, comprising:

[0006] The outer casing has a worktable in the middle, a moving mechanism on the worktable, a positioning plate on the moving mechanism, and multiple positioning holes on the positioning plate.

[0007] A mounting plate is set above the workbench, with cylinder rods at both ends of the mounting plate, a cylinder connected to the cylinder rods at the lower end of the workbench, a driver on the mounting plate, and multiple tightening components connected to the driver at the lower end of the mounting plate.

[0008] The tightening assembly includes a rotating drum, a rotating component, and a spring. The rotating component and the spring are located inside the rotating drum, with the spring positioned at the upper end of the rotating component. The rotating drum is connected to the driver via a bolt, which is located between the rotating component and the spring.

[0009] In the assembly and tightening equipment for producing pen holders according to this utility model, the lower end of the driver is provided with a rotating shaft, the rotating shaft is provided with a limiting head, and the rotating cylinder is provided with a limiting hole that cooperates with the limiting head.

[0010] In the assembly and tightening equipment for producing pen holders according to this utility model, an installation chamber is formed in the middle of the rotating drum, and the rotating component and spring are arranged in the installation chamber.

[0011] In the assembly and tightening equipment for producing pen holders according to this utility model, the rotating component has a conical chamber and a movable chamber in the middle, and the conical chamber and the movable chamber are connected by a connecting chamber.

[0012] In the assembly and tightening equipment for producing this pen holder according to the present invention, the rotating component is made of silicone material.

[0013] In the assembly and tightening equipment for producing pen holders according to this utility model, the bolt consists of a rotating body and a rod body. The rotating body is provided with a strip groove. The bolt is inserted from the conical chamber and placed in the movable chamber through the connecting chamber. The rod body is kept to pass through the rotating part, the spring and the rotating cylinder and connected to the driver. The rotating body is set in the movable chamber.

[0014] The assembly and tightening equipment for pen holder production according to this utility model has the following beneficial effects: The equipment uses a silicone rotating component for tightening. During rotation, friction is generated between the rotating component and the outer wall of the pen tip, causing the pen tip to rotate. After rotation, slippage is maintained between the rotating component and the pen tip, preventing the rotating component from further rotating the pen tip, thus ensuring that each pen tip is precisely tightened onto the pen holder. This significantly improves the assembly efficiency between pen tips and pen holders, reduces the labor intensity of workers, and increases production progress. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1 to 7As shown, the assembly and tightening device for producing this pen holder according to this utility model includes a housing 1 and a mounting plate 2. A workbench 3 is located in the middle of the housing 1, and a moving mechanism 4 is mounted on the workbench 3. A positioning plate 5 is mounted on the moving mechanism 4, and multiple positioning holes 6 are provided on the positioning plate 5. The moving mechanism 4 is used to cooperate with the tightening assembly 7, allowing the moving mechanism 4 to move the positioning plate 5 so that it is positioned at the lower end of the tightening assembly 7. The positioning holes 6 are used for inserting the pen holder, then placing the pen tip on the pen holder, and pre-tightening the pen tip to prevent it from tilting, thus facilitating the tightening of the tightening assembly 7.

[0024] Since there are multiple positioning holes 6 on the positioning plate 5, multiple pen holders can be inserted. However, the number of tightening components 7 on the mounting plate 2 is less than the number of positioning holes 6. Therefore, after the tightening components 7 tighten the pen tips that are located on part of the positioning plate 5, the positioning plate 5 needs to be moved a certain distance by the moving mechanism 4 so that the pen tips that are not tightened can be moved to the lower end of the tightening components 7.

[0025] Mounting plate 2 is positioned above workbench 3. Cylinder rods 8 are located at both ends of mounting plate 2. A cylinder connected to the cylinder rods 8 is located at the lower end of workbench 3. The cylinder can drive the cylinder rods 8 to move up and down, thus causing mounting plate 2 to move up and down accordingly. A driver 9 is mounted on mounting plate 2, and multiple tightening assemblies 7 connected to the driver 9 are located at the lower end of mounting plate 2. The driver 9 can be a motor, which drives a rotating shaft 10 to rotate, which in turn drives the tightening assemblies 7 to rotate.

[0026] The tightening assembly 7 includes a rotating drum 11, a rotating component 12, and a spring 13. The rotating component 12 and the spring 13 are located inside the rotating drum 11, with the spring 13 positioned at the upper end of the rotating component 12. The rotating drum 11 is connected to the driver 9 via a bolt 14, which is positioned between the rotating component 12 and the spring 13.

[0027] A rotating shaft 10 is provided at the lower end of the driver 9. A limiting head 15 is provided on the rotating shaft 10, and a limiting hole 16 that cooperates with the limiting head 15 is provided on the rotating drum 11. Through the cooperation of the limiting head 15 and the limiting hole 16, the rotating shaft 10 and the rotating drum 11 will not have angular displacement. When the rotating shaft 10 rotates, it can drive the rotating drum 11 to rotate, keeping the speed of the rotating drum 11 consistent with that of the rotating shaft 10.

[0028] A mounting chamber 17 is formed in the middle of the rotating cylinder 11, and the lower end of the mounting chamber 17 is kept open. The rotating component 12 and the spring 13 are disposed in the mounting chamber 17. The spring 13 is located at the upper end of the rotating component 12. When the rotating component 12 is placed on the pen tip, the cylinder will drive the rotating component 12 to press down on the pen tip, keeping the rotating component 12 under force on the pen tip, thereby generating a large friction force, which makes it easy for the rotating component 12 to drive the pen tip to rotate and tighten it on the pen cylinder.

[0029] The rotating part 12 has a conical chamber 18 and a movable chamber 19 in the middle. The conical chamber 18 is located at the lower end of the movable chamber 19. The conical chamber 18 and the movable chamber 19 are connected by a connecting chamber 20. The shape of the connecting chamber 20 is consistent with the shape of the rotating body 21, which facilitates the insertion and installation of the rotating body 21.

[0030] Bolt 14 consists of a rotating body 21 and a rod 22. The rotating body 21 is provided with a strip groove 23. Bolt 14 is inserted into the conical chamber 18 and placed in the movable chamber 19 through the connecting chamber 20. The rod 22 is kept to pass through the rotating part 12, the spring 13 and the rotating cylinder 11 and connected to the driver 9. The rotating body 21 is set in the movable chamber 19.

[0031] The rotating component 12 is provided with a first through hole 121, the rotating cylinder 11 is provided with a second through hole 122, and the rotating shaft 10 is provided with a fixing hole 123 that cooperates with the rod body 22.

[0032] When the bolt 14 installs the rotating part 12 and the spring 13 into the mounting chamber 17, it is necessary to maintain the deflection angle between the position of the rotating body 21 and the connecting chamber 20, so that when the rotating part 12 applies pressure to the spring 13, the rotating body 21 will not be kept exactly aligned with the connecting chamber 20 and reach the connecting chamber 20.

[0033] The rotating part 12 is made of silicone. Because the rotating part 12 is made of silicone, it has a certain elasticity. When the cylinder moves the rotating part 12 down to the pen tip, the rotating part 12 can deform and keep the inner wall of the conical chamber 18 in contact with the pen tip, generating friction. After the driver 9 is started, the rotating part 12 drives the pen tip to rotate, so that the pen tip can be installed on the pen holder.

[0034] When the pen tip is tightened, since the pen tip remains stationary, the friction between the pen tip and the rotating part 12 is less than the fixing force between the pen tip and the pen holder, which is consistent with the fixing force of the pen holder inserted into the positioning hole 6. This causes slippage between the rotating part 12 and the pen tip, thus preventing the rotating part 12 from continuing to drive the pen tip to rotate, completing the assembly between the pen tip and the pen holder, and improving production efficiency.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
