The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Example 1, see Figures 1-6 This embodiment provides a vehicle motor housing positioning tool, including a base 5, a support column 7 is mounted on the top of the base 5, a motor base 8 is mounted on the top of the base 5, a motor 6 is mounted on the top of the motor base 8, and a movable plate 1 is hinged on the top of the support column 7; The top of the movable plate 1 is equipped with an insertion rod 21, and a slide groove is opened at the top of the movable plate 1. The inner wall of the slide groove is rotatably connected to the first rotating rod 211, and the outer wall of the first rotating rod 211 is fixedly sleeved with a first moving rod 22. The top of the first moving rod 22 is hinged with a second moving rod 23, and the left side of the first moving rod 22 and the left side of the second moving rod 23 are equipped with an elastic telescopic rod 24. The inner wall of the insertion rod 21 is fixedly connected to the limit rod, and the first moving rod 22 is slidably connected to the outer wall of the limit rod, and the outer wall of the first moving rod 22 is equipped with a first hydraulic warehouse 25. The outer wall of the first rotating rod 211 is fixedly sleeved with a first ratchet 212, and the front of the movable plate 1 is hinged with a first pawl 213. The top of the movable plate 1 is equipped with a spraying device 3 for spraying lubricating oil, and the top of the movable plate 1 is equipped with an expansion device 4 for assisting in clamping the motor seat 8. The base 5 is the foundation, and the motor 6 and the movable plate 1 are supported and connected respectively by the support column 7 and the motor seat 8. When the motor housing needs to be positioned, the insertion rod 21 on the top of the movable plate 1 realizes flexible clamping of the motor housing under the coordinated action of the first rotating rod 211, the first moving rod 22, the second moving rod 23 and the elastic telescopic rod 24. Among them, the first rotating rod 211 rotates in the slide groove, driving the first moving rod 22 and the second moving rod 23 to adjust to the appropriate position and angle, and the elastic telescopic rod 24 provides adaptive deformation to evenly distribute the clamping force and avoid damage to the motor housing. At the same time, the sliding connection between the limit rod and the first moving rod 22 ensures the stability and accuracy of the movement of the moving rod. The first hydraulic tank 25 provides power support for the entire clamping process, and realizes efficient transmission and control of force through hydraulic transmission. The cooperation of the first ratchet 212 and the first pawl 213 ensures the unidirectionality and stability of the transmission, and prevents loosening or displacement during the clamping process. Furthermore, the spraying device 3 mounted on top of the movable plate 1 can spray lubricating oil in a timely and quantitative manner through the vertical plate 31, second rotating rod 32, blocking block 33, external oil pipe 34, and other components when the motor 6 is operating, thereby reducing friction and wear on the internal components of the motor 6 and extending the service life of the motor 6. The airbag 41 in the expansion device 4, inflated by the action of the third hydraulic assembly, assists in clamping the motor base 8 from the inside, further enhancing the overall stability and ensuring the stable operation of the motor 6 during operation. This improves production efficiency and processing accuracy, and reduces maintenance costs and labor intensity, thus becoming a highly efficient and reliable vehicle motor housing positioning tool. The first hydraulic assembly includes a first hydraulic reservoir 25, which is fixedly connected to the side of the first moving rod 22. The first hydraulic reservoir 25 has a piston at one end slidingly connected to the first hydraulic rod 26. The outer wall of the first hydraulic rod 26 is movably sleeved with a first spring 27. The first hydraulic reservoir 25 is fixedly connected to the side of the first moving rod 22. The first hydraulic rod 26 with a piston at one end slidingly connected thereto can accurately convert hydraulic energy into mechanical energy, providing strong and stable force support for the forward and backward movement of the first moving rod 22.The first spring 27 is movably mounted on the outer wall of the first hydraulic rod 26. During the extension and retraction of the first hydraulic rod 26, it plays a key role in buffering and resetting, effectively reducing mechanical shock and improving the service life and reliability of the entire device. When the motor housing needs to be clamped, hydraulic oil enters the first hydraulic chamber 25, pushing the first hydraulic rod 26 to extend, driving the first movable rod 22 forward, and then causing the second movable rod 23 to move in conjunction with it, completing the clamping of the motor housing. When releasing the motor housing, the hydraulic oil flows in the opposite direction, and the first hydraulic rod 26 retracts under the elastic force of the first spring 27, and the first and second movable rods 22 and 23 are also reset. The entire process is smooth, fast, and precise, ensuring efficient execution of the clamping and release actions, and improving the automation and work efficiency of the motor housing positioning tooling. The top of the movable plate 1 is equipped with a second hydraulic chamber 29. The second hydraulic rod 210 is slidably connected to the piston at one end of the second hydraulic chamber 29. The bottom of the first hydraulic chamber 25 is fixedly connected to the first connecting hose 28, and the end of the first connecting hose 28 away from the first hydraulic chamber 25 is fixedly connected to the top of the second hydraulic chamber 29. A sliding groove for sliding the limiting rod is provided on the front side of the first moving rod 22 , and the first pawl 213 and the first ratchet wheel 212 are engaged with each other.

[0026] When the above device is used, the movable plate 1 is pushed to rotate counterclockwise, the notch of the movable plate 1 is buckled on the outer wall of the support column 7, and the second moving rod 23 and the first moving rod 22 are pushed to rotate counterclockwise. The first moving rod 22 drives the second moving rod 23 to move to the left, and the first moving rod 22 drives the limiting rod and the insertion rod 21 to move to the left through the slide groove, and the insertion rod 21 is plugged into the inner wall of the notch of the motor seat 8. During the counterclockwise rotation of the first moving rod 22, the first rotating rod 211 also rotates counterclockwise, and the first rotating rod 211 drives the first ratchet 212 to rotate counterclockwise, and the insertion rod 21 is locked by the first ratchet 212 and the first pawl 213, and the outer wall of the motor 6 is assembled. After assembly, the second moving rod 23 is pushed to move to the right, and the second moving rod 23 is pushed to move to the left. The movable rod 23 rotates clockwise, the second movable rod 23 squeezes the first hydraulic rod 26, and the first spring 27 is squeezed, and the first hydraulic rod 26 moves to the bottom. During the descending process of the first hydraulic rod 26, the internal pressure of the first hydraulic chamber 25, the first connecting hose 28, and the second hydraulic chamber 29 increases, driving the second hydraulic rod 210 to rise, driving the first pawl 213 to rise, so that the first pawl 213 no longer limits the first ratchet 212. When the second movable rod 23 squeezes the first hydraulic rod 26 to the limit distance, the second movable rod 23 drives the first movable rod 22 to rotate clockwise, and the first movable rod 22 drives the insertion rod 21 to move to the right, so that the insertion rod 21 is reset. At the same time, the elastic telescopic rod 24 drives the second movable rod 23 to restore the vertical state. Figure 5 As shown, the first spring 27 also drives the first hydraulic rod 26 to reset, as shown in FIG. Figure 5As shown, the second hydraulic rod 210 is lowered, so that the first pawl 213 limits the first ratchet 212 again, as shown in FIG. Figure 6 shown.

[0027] Example 2, see Figures 1-8 Based on the first embodiment, the spraying device 3 includes a vertical plate 31, which is fixedly connected to the top of the movable plate 1. A second rotating rod 32 is rotatably connected to the front of the vertical plate 31. A blocking block 33 is fixedly connected to the outer wall of the second rotating rod 32. An external oil pipe 34 is mounted on the inner wall of the vertical plate 31. A circular gear 37 is rotatably connected to the vertical plate 31 via a bearing. A second pawl 36 is hingedly connected to the inner wall of the circular gear 37. A second ratchet 35 is fixedly connected to the outer wall of the second rotating rod 32. A second hydraulic assembly is mounted on the top of the movable plate 1. The vertical plate 31 is fixedly connected to the top of the movable plate 1 and serves as the support structure for the entire spraying device 3. The second rotating rod 32 is rotatably connected to the front of the vertical plate 31. The blocking block 33 is fixedly connected to its outer wall to control the opening and closing of the lubricating oil spray port. The external oil pipe 34 has one end connected to the external oil tank and the other end facing the first movable rod 22. The external oil pipe 34 is mounted on the inner wall of the vertical plate 31 and is responsible for transporting the lubricating oil to the spray port. The vertical plate 31 is rotatably connected to a circular gear 37 via a bearing, which, along with the second pawl 36 and second ratchet wheel 35, forms a sophisticated transmission system. To spray lubricating oil, the second rotating rod 32 rotates the blocking block 33, opening the spray port. The engagement of the second ratchet wheel 35 and the second pawl 36 ensures unidirectional and stable transmission, allowing the lubricating oil to be accurately and evenly sprayed onto the outer wall of the first movable rod 22. Furthermore, a second hydraulic assembly mounted on top of the movable plate 1 provides power to the spraying device 3, ensuring the timely and accurate spraying action. The second hydraulic assembly includes a third hydraulic chamber 39, and a piston at one end inside the third hydraulic chamber 39 is slidably connected to a rack 38, and the rack 38 is engaged with a circular gear 37. A fourth hydraulic chamber 310 is assembled on the side of the first movable rod 22, and a piston at one end inside the fourth hydraulic chamber 310 is slidably connected to a third hydraulic rod 311, and a second spring 313 is movably sleeved on the outer wall of the third hydraulic rod 311. A second connecting hose 312 is fixedly connected to the top of the third hydraulic chamber 39, and an end of the second connecting hose 312 away from the third hydraulic chamber 39 is fixedly connected to the back of the fourth hydraulic chamber 310.

[0028] When the above-mentioned device is used, by connecting the external oil pipe 34 to the external oil tank, when the second moving rod 23 squeezes the third hydraulic rod 311, the second spring 313 is squeezed at the same time, and the third hydraulic rod 311 descends, the internal pressure of the fourth hydraulic chamber 310, the second connecting hose 312, and the third hydraulic chamber 39 increases, driving the rack 38 to move to the left, and the rack 38 drives the circular gear 37 to rotate, and the circular gear 37 drives the second pawl 36 to slide across the outer wall of the second ratchet 35. When the insertion rod 21 is reset and the second moving rod 23 is released, the elastic telescopic rod 24 drives the second moving rod 23 to reset and no longer squeezes the third hydraulic rod 311. After the second spring 313 drives the third hydraulic rod 311 to reset, it drives the rack 38 to move to the right and reset. Figure 8 As shown, the rack 38 drives the circular gear 37 to rotate during the resetting process, the circular gear 37 drives the second pawl 36 to rotate, the second pawl 36 drives the second ratchet 35 to rotate, the second ratchet 35 drives the second rotating rod 32 to rotate, and the second rotating rod 32 drives the blocking block 33 to rotate. During the rotation of the blocking block 33, lubricating oil is sprayed on the reset first moving rod 22 through the external oil pipe 34 to prevent it from getting stuck.

[0029] Example 3, see Figures 1-9Based on the first embodiment, the expansion device 4 includes an airbag 41. A circular notch is defined on the left side of the movable plate 1, and the airbag 41 is fixedly connected to the inner wall of the circular notch. A third hydraulic assembly is mounted on the top of the movable plate 1. The airbag 41 is fixedly connected to the inner wall of the circular notch defined on the left side of the movable plate 1. Through inflation, the airbag 41 achieves a tight fit and clamping of the interior of the motor base 8. When the motor base 8 needs to be secured, the fifth hydraulic chamber 42 of the third hydraulic assembly begins to operate. A fourth hydraulic rod 43, slidably connected to a piston at one end, extends under the action of hydraulic oil, pushing the extrusion rod 45 downward. This pressurizes the hydraulic oil into the airbag 41 through the connecting pipe 44, causing the airbag 41 to rapidly expand. This applies a uniform clamping force to the motor base 8 from the inside, enhancing overall stability. This clamping method using the expansion of the airbag 41 not only accommodates motor bases 8 of varying shapes and sizes but also effectively avoids deformation or damage to the motor base 8 that can occur with traditional rigid clamping, thereby improving the reliability and safety of the clamping. At the same time, the flexible contact characteristics of the airbag 41 can absorb certain vibrations and impacts during the operation of the motor 6, further improving the stability and service life of the motor 6. In addition, by precisely controlling the flow and pressure of the hydraulic oil in the fifth hydraulic chamber 42, the expansion degree of the airbag 41 can be flexibly adjusted to achieve precise adjustment of the clamping force, meet the assembly and processing requirements of different motor seats 8, enhance the versatility and practicality of the entire positioning tooling, and is a highly innovative auxiliary clamping device. The third hydraulic assembly includes a fifth hydraulic chamber 42, the fifth hydraulic chamber 42 is fixedly connected to the top of the movable plate 1, the piston at one end of the fifth hydraulic chamber 42 is slidably connected to the fourth hydraulic rod 43, the top of the fourth hydraulic rod 43 is fixedly connected to the extrusion rod 45, the left side of the fifth hydraulic chamber 42 is fixedly connected to the connecting pipe 44, and the end of the connecting pipe 44 away from the fifth hydraulic chamber 42 is fixedly connected to the outer wall of the airbag 41.

[0030] When the above-mentioned equipment is in actual use, the second movable rod 23 drives the fourth hydraulic rod 43 to descend during the counterclockwise rotation. During the descent of the fourth hydraulic rod 43, the internal pressure of the fifth hydraulic chamber 42 and the connecting pipe 44 increases, driving the airbag 41 to expand and fix the motor base 8.
