Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tensioner assembly, in particular to a tool for tensioner assembly. BACKGROUND

[0002] In the prior art, the assembly of the tensioner is usually manually assembled by multiple people. 1. Safety: For chain tensioners, the assembly space is limited, and there is a safety hazard of personnel bumping and scratching. For belt tensioners, employees use copper rods to knock the hoops for assembly, which has a safety hazard of bruising hands and splintering eyes. 2. Quality: For chain tensioners, prying the rod to rotate the transmission sprocket can easily cause scratches on the paint surface of the lug, with a problem occurrence rate of 1.7%. For belt tensioners, knocking the hoops with a copper rod causes damage to the paint surface, resulting in quality degradation. 3. Efficiency: For chain tensioners, the assembly method is complicated, and multiple employees are needed to adjust the tensioner and the transmission sprocket, with a single assembly time of 342". For belt tensioners, the operation efficiency is low, with 8-15 knocks required for each, taking about 1 minute; the labor intensity is large.

[0003] To this end, Chinese invention patent application No. CN202322833181.3 discloses a tensioner assembly tool, which, when assembling the tensioner, rotates the handle, and the handle drives the push rod to extend or retract relative to the support through the connecting rod, thereby pushing and assembling the tensioner. Safety: Eliminates the safety hazard of squeezing the fingers of personnel when manually assembling the tensioner fixing bolt. Avoids concentrated work of personnel, reduces the number of employees from three to two at the post, and eliminates the bumping and scratching caused by personnel during concentrated work. Quality: Eliminates the quality problem of the belt loosening caused by the personnel's small assembly force, which makes the tensioner unable to reach the correct assembly position during assembly. There is no need for personnel to rotate the transmission sprocket with a prying rod, eliminating the quality problem of the prying rod scratching the paint surface of the lug. Efficiency: The use of a special tool for assembly reduces the assembly time of a single unit and improves efficiency. Eliminates the complicated steps of hanging and assembling, and directly hangs and assembles after pressing the tool.

DETAILED DESCRIPTION

[0023] The technical solution in the embodiment of the present application is to solve the problem that the connecting hole is difficult to install and fix multiple different tensioners, and the general idea is as follows:

[0024] Embodiment one:

[0025] As shown in Figure 1 , a tool for assembling a tensioner includes a handle 1, a support 2, a link 4 and a push rod 3. One end of the handle 1 is hinged to one end of the support 2, the middle part of the handle 1 is hinged to one end of the link 4, and the other end of the link 4 is hinged to the push rod 3. The push rod 3 is slidingly installed on the support 2. When assembling the tensioner, the handle 1 is turned, the handle 1 drives the push rod 3 to extend and retract relative to the support 2 through the link 4, and the push rod 3 is pushed and assembled to the tensioner.

[0026] ​The other end of the push rod 3 penetrates the other end of the support 2 and is connected with the telescopic piece 7, the outer end of the telescopic piece 7 is provided with the push plate 8, the middle part of the push plate 8 is provided with the connecting hole 81, and the adjusting fixing piece 9 matched with the connecting hole 81 is arranged and used for installing various different tensioning wheels.

[0027] In the embodiment, the cooperation of the adjusting fixing piece 9 and the connecting hole 81 on the push plate 8 facilitates the installation and fixing of various different sizes of tensioning wheels, so that the applicability of the application is increased.

[0028] As shown in Figure 1 and Figure 3 , the outer end of the push rod 3 is provided with a cavity, the telescopic piece 7 includes the adjusting rod 71 inserted into the cavity, the convex block 72 is fixed on the outer wall of the push rod 3, and the locking bolt A73 extending into the cavity is screwed on the convex block 72, and the strip-shaped groove 711 for the locking bolt A73 to abut is formed on the side edge of the adjusting rod 71. Specifically, the locking bolt A73 is loosened, the adjusting rod 71 inserted into the cavity is moved, the locking bolt A73 is tightened after being adjusted to the appropriate position, so that the locking bolt A73 abuts against the inner wall of the strip-shaped groove 711, so that the assembly position of the tensioning wheel is indirectly adjusted.

[0029] The anti-skid rubber pad (not shown) abutting against the end of the locking bolt A73 is fixed in the inner part of the strip-shaped groove 711. Specifically, the anti-skid rubber pad can increase the friction force when the locking bolt A73 abuts against the strip-shaped groove 711, which indirectly increases the stability of the tensioning wheel after adjustment.

[0030] As shown in Figure 1 , the push plate 8 is designed to be inclined relative to the adjusting rod 71. Specifically, the push plate 8 is arranged, so that the push rod 3 of the tensioning wheel assembly tool abuts against the tensioning wheel, and the tensioning wheel is quickly assembled.

[0033] As shown in Figure 1 The connecting rod 4 is provided with a pin shaft B6 at one end, and is connected with the middle part of the handle 1 through the pin shaft B6. The handle 1 is rotatably connected with the connecting rod 4, the handle 1 drives the connecting rod 4 to rotate, the occupied area of the expander wheel assembly tool is reduced, and the structure is compact.

[0034] As shown in Figure 1 The support 2 is further provided with a U-shaped clamping seat at one end through a pin shaft C, and one end of the support 2 is located in the U-shaped clamping seat. The U-shaped clamping seat is arranged to facilitate the abutment of the expander wheel assembly tool and the supporting component near the expander wheel through the U-shaped clamping seat, and facilitates the fixation and support of the expander wheel assembly tool.

[0035] As shown in Figure 1 The other end of the support 2 is provided with a limiting column 10 and a limiting plate 11, one end of the limiting column 10 is connected with the other end of the support 2, the limiting plate 11 is connected with the other end of the limiting column 10, the limiting column 10 is perpendicular to the limiting plate 11, and the limiting plate 11 is a circular plate body. Specifically, the limiting column 10 and the limiting plate 11 are arranged to facilitate the limiting clamping of the expander wheel assembly tool and the strip-shaped hole near the expander wheel, and facilitate the fixation and support of the expander wheel assembly tool. The limiting column 10 is perpendicular to the limiting plate 11, which facilitates the limiting clamping of the expander wheel assembly tool and the strip-shaped hole near the expander wheel, and facilitates the fixation and support of the expander wheel assembly tool. The limiting plate 11 is a circular plate body, which facilitates the installation and sliding of the limiting plate 11 into the strip-shaped hole through the mounting circular hole of the expander wheel.
