Description

Technical Field

[0001] The utility model relates to the field of tension wheel assembly equipment, in particular to a tension wheel assembly pressing device. Background Art

[0002] The tensioner is a fundamental component used in the tensioning device of a transmission system. It consists of a friction unit, a torsion spring, a bearing, a pulley, and other components. It is widely used in various machinery manufacturing applications, such as automobiles, tractors, machine tools, printing presses, and textile machines.

[0003] At present, the traditional assembly process of the tensioner is as follows: the staff places the various components of the tensioner on the workbench, and then the staff manually assembles the components one by one, and uses a handheld rivet gun to press a circle of rivets on the top surface of the tensioner, which takes a lot of time and has low assembly efficiency.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0007] A tension wheel assembly and pressing device, comprising:

[0008] A fixing frame, to which a fixing plate is slidably connected;

[0009] A cylinder, the cylinder is mounted on the top of the fixed frame, the piston rod of the cylinder is connected to a tooling body, the tooling body is fixed to the fixed plate, a pulley 1 is rotatably connected in the tooling body, and a rivet head is eccentrically provided at the bottom of the pulley 1;

[0010] A reducer is installed on a fixed plate, a second pulley is installed on the output shaft of the reducer, and a transmission belt is arranged between the second pulley and the first pulley.

[0011] Furthermore, the fixing frame is provided with a guide rail arranged in a vertical direction, and the fixing plate is slidably connected to the guide rail.

[0017] Furthermore, a bearing 1 is provided between the inner wall of the cavity of the tooling body and the rotating shaft base.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. When rivets need to be pressed into the tensioning pulley, the piston rod of the cylinder drives the tooling body and the pulley to reciprocate in the vertical direction, and the rivet head makes the same movement to press the rivet into the tensioning pulley. Then the reducer starts, drives the pulley to rotate, drives the rivet head to rotate to the next rivet, repeats the action, and presses a circle of rivets into the tensioning pulley at the top of the tensioning pulley, automatically completing the riveting work, reducing assembly time and improving work efficiency.

[0020] 2. The two guide rails are used to limit the movement direction of the rivet to the vertical direction, ensuring the riveting accuracy of the rivet head.

[0021] 3. Bearing 1 and bearing 2 are used to reduce the friction resistance of pulley 1 and facilitate the rapid rotation of pulley 1 to achieve the replacement of the rivet head. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example:

[0029] A tension wheel assembly pressing device, such as Figure 1 As shown, the device comprises a fixed frame 1, the front of which is provided with two vertically arranged guide rails 11, which are arranged parallel to each other. A fixed plate 12 is provided on the fixed frame 1, which is slidably connected to the guide rails 11. During operation, the fixed plate 12 and other components mounted on the fixed plate 12 reciprocate in the vertical direction. A horizontally arranged mounting plate 13 is provided on the top of the fixed frame 1.

[0030] like Figure 1 and Figure 2 As shown, the tensioning wheel assembly and pressing device includes a cylinder, which is installed on the top of the fixed frame 1. Specifically, the cylinder is installed on the top of the fixed plate 12, and the piston rod of the cylinder is arranged vertically downward. The piston rod of the cylinder is connected to a tooling body 22, and the tooling body 22 is fixed to the fixed plate 12. During operation, the piston rod of the cylinder performs telescopic movement, driving the tooling body 22 and the fixed plate 12 to also perform reciprocating movement in the vertical direction. A connector 21 is provided at the end of the piston rod of the cylinder. The connector 21 and the tooling body 22 are fixed by bolts to improve the stability of the connection between the tooling body 22 and the piston rod of the cylinder.

[0031] like Figure 1 and Figure 2As shown, a cavity is formed inside the tooling body. A pulley 23 is rotatably connected to the tooling body 22. A rotating shaft 231 is provided on the top of the pulley 23 and is inserted into the cavity of the tooling body 22. A rotating shaft 231 base is provided at the bottom of the rotating shaft 231. The rotating shaft 231 base and the pulley 23 are fixed by bolts to ensure the stability of the fixed position of the rotating shaft 231. A bearing 24 is provided between the inner wall of the cavity of the tooling body 22 and the base of the rotating shaft 231. The bearing 24 reduces the friction resistance encountered by the rotating shaft 231 during rotation. A housing 221 is fixed to the outside of the tooling body 22. A bearing 25 is provided between the inner wall of the housing 221 and the base of the rotating shaft 231. Similarly, the bearing 25 reduces the friction resistance between the housing 221 and the base of the rotating shaft 231. A rivet head 232 is eccentrically provided at the bottom of the pulley 23. The rivet head 232 presses the rivet into the tensioning pulley to complete the riveting work.

[0032] like Figure 1 and Figure 3 As shown, the tensioning wheel assembly and pressing device includes a reducer 3, which is mounted on the fixed plate 12 and arranged in the vertical direction. A second pulley 31 is fixed to the end of the output shaft of the reducer 3. The second pulley 31 and the first pulley 23 are at the same height. A transmission belt 32 is provided between the second pulley 31 and the first pulley 23. When switching the riveting position, the reducer 3 is started, the second pulley 31 rotates to drive the first pulley 23, and the riveting head 232 switches its position.

[0033] Specific working process:

[0034] When rivets need to be pressed into the tensioning pulley, the staff first places the tensioning pulley in the designated workstation and places several rivets into the rivet holes on the top of the tensioning pulley. The cylinder is then started, and the piston rod of the cylinder moves downward, driving the tooling body 22 and the fixed plate 12 to move downward as well, thereby causing the pulley 1 23 to move downward, and the rivet head 232 presses the rivets into the tensioning pulley. The piston rod of the cylinder then moves upward, and then the reducer 3 is started, driving the pulley 1 23 to rotate, driving the rivet head 232 to rotate to the next rivet, and repeating the above actions to press a circle of rivets into the corresponding holes of the tensioning pulley at the top of the tensioning pulley, quickly completing the riveting work.

[0035] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
