Description

Technical Field

[0001] This application relates to the field of engines, and more specifically, to a labor-saving pulley shock absorber pull-out tooling. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors. Internal combustion engines, for example, typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine including the power unit. For a long time, repair technicians have used screw pullers to remove engine pulley shock absorbers. When there are quality problems or assembly issues with engine peripheral components, removing the engine pulley shock absorber to replace gear chambers, shims, camshafts, gears, crankshafts, etc., is a headache for repair technicians (especially for six-cylinder engines). This is because the currently used screw pullers are very inefficient, labor-intensive, and require maintaining the tool perpendicular to the pulley when tightening bolts, which is time-consuming and labor-intensive, significantly consuming the repair technician's physical strength and time. Summary of the Invention

[0003] To overcome the shortcomings of the existing system, this application provides a labor-saving puller puller tool, which can solve the problems of the very low efficiency and high labor intensity of the currently used spiral puller when pulling out the puller, and the time and effort required to keep the tool perpendicular to it when tightening the bolts, which greatly consumes the physical strength and time of the repairman.

[0004] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0005] A labor-saving pull-out fixture for a belt puller includes a pull-out assembly and a support assembly.

[0006] The pulling assembly includes a jack, an internal threaded ring, a rotating plate, and connecting bolts. The internal threaded ring is threadedly connected to the jack, and the rotating plate is rotatably sleeved on the internal threaded ring. Multiple connecting bolts are provided, and the connecting bolts slide through the rotating plate.

[0007] The support assembly includes a movable base, a housing, a connecting plate, a threaded rod, and a transmission rod. The housing is disposed on the top of the movable base, the connecting plate is slidably disposed within the housing, the jack is disposed on the top of the connecting plate, the threaded rod is rotatably disposed within the housing, and the connecting plate is threadedly sleeved onto the threaded rod. The transmission rod is disposed within the movable base and is drively connected to the threaded rod.

[0008] In one specific implementation, the jack is fixedly connected to an external threaded ring, and the internal threaded ring is threadedly connected to the external threaded ring.

[0009] In the above implementation process, an external threaded ring is set to cooperate with an internal threaded ring, so that the internal threaded ring can be tightened to connect to the external threaded ring.

[0011] In the above implementation process, by opening an annular groove, the rotating plate rotates relative to the internal threaded ring within the annular groove.

[0012] In one specific implementation, the rotating plate has multiple strip-shaped holes, which face the center of the rotating plate.

[0013] In the above implementation process, by opening multiple strip holes facing the center of the rotating plate, the sliding adjustment connecting bolt can be moved and adjusted along the strip holes.

[0014] In one specific implementation, the top of the connecting plate has a slot, and the bottom of the jack has a T-shaped insert plate that is inserted into the slot.

[0015] In the above implementation process, by opening a slot, the jack can be connected to the slot through a T-shaped insert plate, which facilitates the connection.

[0016] In one specific implementation, the movable seat includes a base plate and casters, the casters being mounted on the bottom of the base plate.

[0017] In one specific implementation, the base plate has an inner cavity, the transmission rod rotates through the inner cavity, and the transmission rod is fixedly connected to a worm gear. The bottom end of the threaded rod extends into the inner cavity, and the threaded rod is fixedly connected to a worm wheel.

[0018] In the above implementation process, by setting up a worm gear and a worm, when the rotating transmission rod drives the worm to rotate, the worm meshes and drives the worm gear to rotate, and the worm gear drives the threaded rod to rotate.

[0019] In one specific implementation, a handwheel is fixedly connected to the end of the transmission rod away from the worm gear.

[0020] In the above implementation process, a handwheel is provided to facilitate the rotation of the transmission rod by turning the handwheel.

[0021] The advantages of this embodiment are: by setting up a jack, an internal threaded ring, a rotating plate, and connecting bolts, the jack is used for labor-saving pulling; by setting up a movable seat, a housing, a connecting plate, a threaded rod, and a transmission rod, the entire assembly can be easily moved to the side of the engine pulley; then, by rotating the transmission rod, the threaded rod is driven to rotate, and the threaded rod drives the connecting plate to move through the threaded transmission connection; the connecting plate moves to adjust the height, and the movable assembly facilitates easy adjustment and alignment with the pulley position, saving time and effort and improving efficiency.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0030] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0031] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0032] Please see Figures 1-6This application provides a labor-saving pull-out fixture for a belt puller shock absorber, including a pull-out assembly 100 and a support assembly 200.

[0033] Please see Figure 1 , 2 3 and 4, the pull assembly 100 includes a jack 110, an internal threaded ring 120, a rotating plate 130 and connecting bolts 150. The internal threaded ring 120 is threadedly connected to the jack 110. The rotating plate 130 is rotatably sleeved on the internal threaded ring 120. Multiple connecting bolts 150 are provided, and the connecting bolts 150 slide through the rotating plate 130.

[0034] The jack 110 is fixedly connected to an external threaded ring 160, and an internal threaded ring 120 is threadedly connected to the external threaded ring 160. By setting the external threaded ring 160 to cooperate with the internal threaded ring 120, the internal threaded ring 120 can be tightened to connect to the external threaded ring 160.

[0035] Specifically, an annular groove 121 is provided on the outer side of the internal threaded ring 120, and the rotating plate 130 is rotatably disposed in the annular groove 121. By providing the annular groove 121, the rotating plate 130 rotates relative to the internal threaded ring 120 within the annular groove 121.

[0036] In this embodiment, the rotating plate 130 has multiple strip holes 131 facing the center of the rotating plate 130. By opening multiple strip holes 131 facing the center of the rotating plate 130, the sliding adjustment connecting bolt 150 can be moved and adjusted along the strip holes 131.

[0037] Please see Figure 1 , 2 5 and 6, the support assembly 200 includes a movable base 210, a housing 220, a connecting plate 230, a threaded rod 240 and a transmission rod 260. The housing 220 is disposed on the top of the movable base 210, the connecting plate 230 is slidably disposed within the housing 220, the jack 110 is disposed on the top of the connecting plate 230, the threaded rod 240 is rotatably disposed within the housing 220, and the connecting plate 230 is threadedly sleeved onto the threaded rod 240. The transmission rod 260 is disposed within the movable base 210 and is drively connected to the threaded rod 240.

[0038] The connecting plate 230 has a slot 231 on its top, and the jack 110 has a T-shaped insert plate 111 on its bottom. The insert plate 111 is inserted into the slot 231. By opening the slot 231, the jack 110 can be connected to the slot 231 through the T-shaped insert plate 111, which facilitates the connection.

[0039] Specifically, the movable seat 210 includes a base plate 211 and casters 212. The casters 212 are installed at the bottom of the base plate 211. The base plate 211 has an inner cavity 2111. The transmission rod 260 rotates through the inner cavity 2111 and is fixedly connected to a worm gear 261. The bottom end of the threaded rod 240 extends into the inner cavity 2111 and is fixedly connected to a worm wheel 241. By setting the worm wheel 241 and the worm gear 261, when the transmission rod 260 rotates and drives the worm gear 261 to rotate, the worm gear 261 meshes and drives the worm wheel 241 to rotate, and the worm wheel 241 drives the threaded rod 240 to rotate.

[0040] In one specific implementation, a handwheel 262 is fixedly connected to the end of the transmission rod 260 away from the worm gear 261. By setting the handwheel 262, it is convenient to drive the transmission rod 260 to rotate by rotating the handwheel 262.

[0041] The working principle of this labor-saving pulley shock absorber pull-out fixture is as follows: First, the jack 110 is connected to the slot 231 via the T-shaped insert plate 111 for quick assembly. Then, the entire assembly is moved to the vicinity of the engine pulley. The handwheel 262 can be turned to drive the transmission rod 260, which in turn drives the worm gear 261. The worm gear 261 meshes with and drives the worm wheel 241, which in turn drives the threaded rod 240. The threaded rod 240, through the threaded transmission principle, moves the connecting plate 230, which then moves along the housing 220. The jack 110 is lowered and its height adjusted. The tooling moves under the support of the jack 110, allowing adjustment of the position of the rotating plate 130 and connecting bolt 150. This aligns the connecting bolt 150 with the threaded hole on the pulley or shock absorber. The operating handle of the jack 110 then operates, causing the piston of the jack 110 to push out and contact the engine or shaft. The reaction force pulls the pulley or shock absorber off. This process is labor-saving, reducing the workload of repair workers while improving work efficiency and providing a better user experience.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
