Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, specifically to a gearbox oil pan nut assembly device. Background Technology

[0002] To facilitate later installation and fixation, most modern transmission oil pans have nuts pre-installed in fixed holes. This allows them to be directly fixed to the transmission's connecting bolts using adjusting bolts, reducing the difficulty of later installation.

[0003] During the injection molding process, transmission oil pans typically have pre-drilled holes. These holes are usually designed to fit the dimensions of nuts, allowing them to be pressed into the pans later. Currently, inserting nuts into these holes is mostly done manually, using foot-operated, pressure-pressing devices such as small punch presses or telescopic cylinders. This method is inefficient, requiring repeated pressing of the same oil pan while constantly adjusting its position relative to the pressure-pressing device to accommodate the different pressure requirements of nuts in different locations.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0026] Reference Figures 1 to 5 The transmission oil pan nut assembly device shown includes a frame 10, a worktable 20 mounted on the frame 10, and a fixing fixture 30 mounted on the worktable 20. The fixing fixture 30 is provided with at least one clamping mechanism 40. All the clamping mechanisms 40 can cooperate with each other to fix the transmission oil pan onto the top pressure block 31 of the fixing fixture 30. The frame 10 is provided with a lifting platform 11 above the worktable 20. The back of the lifting platform 11 is provided with a top pressure mold 50 that cooperates with the fixing fixture 30. The top pressure mold 50 is provided with a plurality of top pressure columns 51. The extension amount and position of all the top pressure columns 51 on the top pressure mold 50 are adjustable.

[0027] The position of the top-pressing mold 50 on the lifting platform 11 is adjustable, and the position of the fixing fixture 30 can also be adjusted according to the actual situation. The clamping mechanism 40 is also adjustable in installation position to adapt to different vehicle transmission oil pans, ensuring stable clamping. In this application, to avoid hard impacts, a rubber pad is provided on the outward end of the top-pressing column 51 to reduce impact and damage to the nut to be pressed. A control switch is provided on the worktable 20 to control the lifting and lowering of the lifting platform 11. Furthermore, for ease of installation, the top-pressing mold 50 is mounted on the lifting platform 11 with screws.

[0028] This transmission oil pan nut assembly device features a workbench 20 for easy operation. The clamping mechanism 40 presses the transmission oil pan firmly onto the pressure block 31, ensuring its positioning and stability. This helps guarantee the quality of the pressure nut and prevents the transmission oil pan from loosening during the pressing process, which could damage it. Furthermore, all the pressure pins 51 are mounted on the pressure mold 50, and their positions are adjustable to accommodate different vehicle transmission oil pans, enhancing usability.

[0029] In one embodiment of this application, to facilitate the lifting and lowering of the lifting platform 11, a plurality of guide columns 12 are provided on the frame 10, and the lifting platform 11 is movably fitted onto all the guide columns 12. A top-pressure cylinder 13 is provided on the top of the frame 10, and the output end of the top-pressure cylinder 13 is connected to the back of the lifting platform 11. A pair of top-pressure cylinders 13 are provided, respectively located at opposite ends of the top of the frame 10. The two top-pressure cylinders 13 are controlled by the same controller or the same air compressor system to achieve synchronized operation.

[0030] See Figures 1 to 3 In one embodiment of this application, to better compress the transmission oil pan and ensure the accuracy of subsequent assembly, the clamping mechanism 40 includes a mounting block 41 and a locking bolt 42 screwed onto the mounting block 41. The mounting block 41 is mounted on the worktable 20, and one end of the locking bolt 42 is used to press against the outer wall of the transmission oil pan. In this embodiment, the transmission oil pan can be clamped by adjusting the locking bolt 42. However, in this embodiment, the rotation of the locking bolt 42 can easily scratch the outer wall of the transmission oil pan. Therefore, in one embodiment of this application, a protective sleeve is provided at the end of the locking bolt 42 that presses against the transmission oil pan. The protective sleeve can rotate relative to the corresponding end of the locking bolt 42.

[0031] In the above embodiments, the operation is not easy because the locking bolt 42 needs to be rotated, and the tightening efficiency is slow. Therefore, in another embodiment of this application, see... Figure 4 and Figure 5 The clamping mechanism 40 includes a mounting base plate 43, a clamping block 46, a cam 47, and an operating lever 48. The mounting base plate 43 is mounted on the worktable 20. The clamping block 46 is slidably mounted on the mounting base plate 43. The mounting base plate 43 is provided with a return spring 4a for resetting the clamping block 46. The cam 47 is eccentrically mounted on the mounting base plate 43. One end of the operating lever 48 is hinged to the cam 47. The operating lever 48 can only swing relative to the cam 47 along a plane. The outer periphery of the cam 47 can press against the clamping block 46. The mounting base plate 43 is provided with a limit block 45. The swinging end of the operating lever 48 can press against the limit block 45. The operating lever 48 can drive the cam 47 to rotate and push the clamping block 46 to press against the gearbox oil pan.

[0032] In the improved embodiment described above, an eccentric cam 47 is used to press against the clamping block 46, which in turn presses against the side wall of the transmission oil pan. This design simplifies operation. Simultaneously, the cooperation between the operating lever 48 and the limiting block 45 allows the operating lever 48 to be easily locked in place by the limiting block 45, preventing the cam 47 from springing back and achieving a locking mechanism. It should be further noted that in the above embodiment, the operator only needs to control the operating lever 48 to rotate the cam 47, utilizing different eccentricities on the cam 47 to press against the clamping block 46, thereby pressing against the side wall of the transmission oil pan. Furthermore, the cam 47 is equipped with a movable column with an opening at its upper end. One end of the operating lever 48 is hinged within this opening, and the operating lever 48 can also swing along the plane of the opening. This structural design utilizes the restriction of the opening, allowing the operating lever 48 to push the cam 47 to rotate when one end of the operating lever 48 is not coaxial with the movable column. It should be further noted that the operating lever 48 can swing relative to the opening. This design facilitates locking the operating lever 48 onto the limiting block 45, thus locking the entire structure. Furthermore, the position of the limiting block 45 on the mounting base plate 43 is adjustable, making it suitable for the clamping requirements of different types of transmission oil pans.

[0033] See Figure 4 and Figure 5In the above embodiment, to facilitate the installation of the return spring 4a, the abutment block 46 is provided with an open mounting cavity 49. One end of the return spring 4a is connected to the open mounting cavity 49, and the other end of the return spring 4a is connected to the limiting mounting plate 44 on the mounting base plate 43. The limiting mounting plate 44 is also placed in the open mounting cavity 49, which is a more aesthetically pleasing design. It should be noted that a through post 4b is provided in the open mounting cavity 49, and the through post 4b movably passes through the limiting mounting plate 44. This facilitates the sliding of the abutment block 46 relative to the mounting base plate 43. In this embodiment, the outward end of the through post 4b can directly abut against the outer wall of the transmission oil pan, and a pressing head is hinged to it to adapt to the angle of the outer wall of the transmission oil pan. This design is preferred in this application. Furthermore, the through post 4b is actually locked to the abutment block 46, facilitating later installation on the limiting mounting plate 44 and the installation of the return spring 4a. Of course, in some improved embodiments, a track is provided on the mounting base plate 43, and the abutment block 46 is slidably mounted on the track.

[0034] See here. Figure 2 In one embodiment of this application, to better adjust the extension of each pressure post 51 and adapt to the clamping operation of transmission oil pans of different vehicle models, the pressure mold 50 is provided with several movable holes 52. One end of each pressure post 51 is movably inserted into the movable hole 52. The lifting platform 11 is provided with several threaded holes that match the movable holes 52. Each threaded hole is screwed with an adjusting bolt 53. One end of the adjusting bolt 53 is threadedly connected to the corresponding end of the pressure post 51. The adjusting bolt 53 can drive the corresponding end of the pressure post 51 to rotate relative to the movable hole 52. When it is necessary to adjust the extension of the pressure post 51, only the extension of the adjusting bolt 53 needs to be adjusted, which is simple and convenient. It should be noted that the diameter of the movable hole 52 is larger than the diameter of the threaded hole, so as to prevent the adjusting bolt 53 from pulling the pressure post 51 out of the threaded hole. In this application, the number and distribution of the threaded holes are distributed according to the actual design requirements, which adapt to the nut installation requirements at different positions on the transmission oil pans of different vehicle models.

[0035] In the actual pressing process, to facilitate the protection of the workbench 20 and the installed nuts, several buffer mechanisms are provided on the workbench 20. The buffer mechanisms can be conventional rubber pads or other structures. For example, each buffer mechanism includes a base mounted on the workbench 20, with an opening on the base. A pressing block is movably inserted into the opening, and a buffer spring is provided between the bottom of the pressing block and the bottom of the opening. This embodiment's structure is not the protected structure of this application, and therefore will not be described in detail here.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
