Description

Technical Field

[0001] The present application relates to the technical field of tensioner pulley assembly, and in particular to a tool for assembling a tensioner pulley. Background Art

[0002] In the prior art, the assembly of tensioners is usually done manually 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 on the clamps for assembly, which poses a safety hazard of hitting hands and burrs injuring eyes. 2. Quality: For chain tensioners, the paint surface of the scion platform is easily scratched when the crowbar turns the transmission sprocket, and the problem incidence rate is 1.7%. For belt tensioners, knocking on the clamps with a copper rod causes damage to the paint surface, resulting in quality degradation. 3. Efficiency: For chain tensioners, the assembly method is cumbersome, and multiple employees are required to adjust the tensioner and the transmission sprocket. The assembly time for a single unit is 342". For belt tensioners, the operating efficiency is low, and each one needs to be knocked about 8-15 times, about 1 minute; the labor intensity is high.

[0003] In this regard, the Chinese invention patent application number is CN202322833181.3, which discloses a tensioner assembly tool. When assembling the tensioner, the handle is turned, and the handle drives the push rod to extend and retract relative to the support through the connecting rod to achieve the pushing and assembly of the tensioner. Safety: It eliminates the safety hazard of squeezing people's fingers when manually assembling the tensioner fixing bolts. Avoid concentrated work of personnel, and reduce the number of assembling positions from three to two, eliminating the bumps and scratches caused by concentrated work. Quality: It eliminates the quality problem of loose belts caused by the failure of personnel to reach the correct assembly position during assembly due to the small assembly force of personnel. There is no need for personnel to use a crowbar to rotate the transmission sprocket, eliminating the quality problem of crowbar scratching the paint surface of the picking platform. Efficiency: Use special tooling for assembly, shorten the assembly time of a single unit, and improve efficiency. Eliminate the cumbersome steps of hanging assembly, and directly hang after pressing with tooling.

DETAILED DESCRIPTION

[0023] The technical solution in the embodiment of the present application is to solve the problem that the connection hole in the above solution is difficult to install and fix a variety of different tensioners. The overall idea is as follows:

[0024] Embodiment 1:

[0025] like Figure 1 As shown, a tool for assembling a tensioner wheel comprises a handle 1, a support 2, a connecting rod 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 connecting rod 4, the other end of the connecting rod 4 is hinged to the push rod 3, and the push rod 3 is slidably installed on the support 2. When assembling the tensioner wheel, the handle 1 is rotated, and the handle 1 drives the push rod 3 to extend and retract relative to the support 2 through the connecting rod 4, thereby realizing the pushing and assembly of the tensioner wheel.

[0026] The other end of the push rod 3 passes through the other end of the support 2 and is connected to a telescopic member 7. A push plate 8 is provided at the outer end of the telescopic member 7. A connecting hole 81 is opened in the middle of the push plate 8, and an adjusting fixing member 9 adapted to the connecting hole 81 and used to install a variety of different tensioning wheels is provided.

[0027] In this embodiment, the adjustment fixing member 9 and the connection hole 81 on the push plate 8 are used to facilitate the installation and fixation of tensioners of various sizes, thereby increasing the applicability of the present application.

[0028] like Figure 1 and Figure 3 As shown, a cavity is provided at the outer end of the push rod 3, and the telescopic member 7 includes an adjusting rod 71 inserted into the cavity, a protrusion 72 is fixed on the outer wall of the push rod 3, and a locking bolt A73 extending into the cavity is screwed on the protrusion 72, and a strip groove 711 for the locking bolt A73 to press against is provided on the side of the adjusting rod 71. Specifically, the locking bolt A73 is loosened, the adjusting rod 71 inserted into the cavity is moved, and the locking bolt A73 is tightened after being adjusted to a suitable position, so that the locking bolt A73 presses against the inner wall of the strip groove 711, so as to facilitate indirect adjustment of the assembly position of the tensioner.

[0029] An anti-skid rubber pad (not shown) is adhered to the inner part of the strip groove 711 and is tightly pressed against the end of the locking bolt A73. Specifically, the design of the anti-skid rubber pad can increase the friction between the locking bolt A73 and the strip groove 711, thereby indirectly increasing the stability of the tensioner after adjustment.

[0030] like Figure 1 As shown, the push plate 8 is designed to be inclined relative to the adjusting rod 71. Specifically, the arrangement of the push plate 8 facilitates the push rod 3 of the tensioner assembly tool to abut against the tensioner, thereby facilitating the rapid assembly of the tensioner.

[0031] like Figure 1 , Figure 4 and Figure 5As shown, the adjustment fixing member 9 includes a plurality of adjustment sleeves 91 with successively reduced diameters and all installed in the connection hole 81, and a connection ear 92 is fixed on both sides of each adjustment sleeve 91, and a clamping notch A82 and a clamping notch B911 for the connection ear 92 to be clamped are respectively provided on the push plate 8 and the adjustment sleeve 91 located outside thereof, and a locking bolt B93 is screwed and fixed on the outer end of the upper surface of each connection ear 92, and a screw hole 83 that communicates with the clamping notch A82 and is compatible with the locking bolt B93 is also provided on the push plate 8. Specifically, according to the diameter size, a plurality of adjustment sleeves 91 are sequentially sleeved and installed in the connection hole 81, and the connection ears 92 on both sides of the adjustment sleeve 91 can be clamped in the corresponding clamping notch A82 or clamping notch B911, and then the adjustment sleeve 91 is fixed to the push plate 8 by the cooperation of the locking bolt B93 and the screw hole 83, so that the installation of tension wheels of various sizes is convenient by disassembling and assembling the adjustment sleeve 91.

[0032] like Figure 1 As shown, a pin A5 is installed at one outer end of the support 2, and is connected to one end of the handle 1 through the pin A5. The handle 1 is a Z-shaped structure, which is convenient for users to operate the handle 1, reduces the operating force, reduces the space occupied by the tensioner assembly tooling, and has a compact structure.

[0033] like Figure 1 As shown, a pin B6 is installed at one end of the connecting rod 4, and the pin B6 is used to connect the middle part of the handle 1. It is convenient for the handle 1 to be rotatably connected with the connecting rod 4, and it is convenient for the handle 1 to drive the connecting rod 4 to rotate, which reduces the occupied area of ​​the tensioner assembly tooling and has a compact structure.

[0034] like Figure 1 As shown, one end of the support 2 is also connected to a U-shaped holder through a pin C, and one end of the support 2 is located in the U-shaped holder. The U-shaped holder is provided to facilitate the tensioner assembly tool to abut against the supporting components near the tensioner through the U-shaped holder, so as to facilitate the fixing and support of the tensioner assembly tool.

[0035] like Figure 1 As shown, a limiting column 10 and a limiting plate 11 are provided at the other end of the support 2. One end of the limiting column 10 is connected to the other end of the support 2, and the limiting plate 11 is connected to 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. Specifically, the setting of the limiting column 10 and the limiting plate 11 facilitates the limiting clamping of the tensioning wheel assembly tooling with the strip hole near the tensioning wheel, and facilitates the fixation and support of the tensioning wheel assembly tooling. The limiting column 10 is perpendicular to the limiting plate 11, and facilitates the limiting clamping of the tensioning wheel assembly tooling with the strip hole near the tensioning wheel, and facilitates the fixation and support of the tensioning wheel assembly tooling. The limiting plate 11 is a circular plate, which facilitates the limiting plate 11 to be installed through the mounting circular hole of the tensioning wheel and slide into the strip hole.

[0036] When using this application:

[0037] According to the diameter, multiple adjustment sleeves 91 are sequentially sleeved and installed in the connection hole 81, and the connection ears 92 on both sides of the adjustment sleeve 91 can be clamped in the corresponding clamping notch A82 or the clamping notch B911, and then the adjustment sleeve 91 is fixed to the push plate 8 by the cooperation of the locking bolt B93 and the screw hole 83, so that the installation of tensioners of various sizes can be facilitated by disassembling and assembling the adjustment sleeve 91, so that the applicability of the present application is increased.
