Description

Technical Field

[0001] This utility model relates to the field of gearbox assembly technology, specifically a gearbox assembly support platform that can rotate 360°. Background Technology

[0002] The automotive transmission is a machine that converts mechanical power into electrical energy. It is the core of a car and has many internal components and a complex structure. Before production, the designed transmission needs to be prototyped and assembled.

[0003] For example, Chinese patent CN106584062A, entitled "Automotive Gearbox Prototype Assembly Table," includes a frame and a rotating worktable. Two opposing bearing seats are mounted on the upper end of the frame. The rotating worktable includes a base plate and two side plates, which are opposite each other and vertically fixed to the base plate. A horizontal rotating shaft is vertically fixed to each side plate, and the horizontal rotating shaft is rotatably connected to the two bearing seats via bearings. One of the horizontal rotating shafts passes through a bearing seat and is fixed to a worm gear. The worm gear is rotatably connected to a worm gear mounting seat via a bearing, and the worm gear meshes with the worm gear. Two opposing gearbox support seats are fixed to the base plate for clamping and fixing the gearbox from both sides. A clamping assembly is rotatably connected to the upper end of the frame for clamping the gearbox from the top surface.

[0004] While the automotive transmission prototype assembly platform in the aforementioned patent is practical and convenient, it also has shortcomings. Currently, during the prototype assembly of transmissions, a traction handwheel is generally used to adjust the rotation angle of the assembly block to facilitate the assembly of the transmission. The traction handwheel can drive large loads with less effort, but precisely because it saves effort, the mechanism itself is also more easily driven in the opposite direction by the load (rotation). If it is used to tow such a heavy-duty transmission in a scenario that may involve safety, there is a risk of slippage. Moreover, even if a worm gear structure is used, the handwheel can still be turned due to accidental activation. Utility Model Content

[0005] The purpose of this invention is to provide a gearbox assembly platform that can rotate 360° to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The 360° rotatable gearbox assembly support platform includes a frame, a transmission assembly, bolts, and a locking assembly. An assembly block is rotatably connected to one side of the frame, and a rotating rod is rotatably connected inside the frame. A handwheel is fixedly sleeved on one end of the rotating rod. When the handwheel is rotated, the assembly block is driven to rotate through the transmission assembly. The bolt is screwed to one end of the rotating rod. When the bolt is unscrewed from the rotating rod, the position of the rotating rod can be locked and fixed by the locking assembly.

[0007] Furthermore, the locking assembly includes a sliding rod and a damping ring. The end of the sliding rod near the handwheel abuts against and fits against one end of the bolt. The sliding rod is slidably connected inside the rotating rod along its length. Two connecting blocks are symmetrically arranged on the sliding rod. The ends of the two connecting blocks that are far apart are fixedly connected to the inner wall of the damping ring. An annular groove is formed inside the frame. The outer diameter of the annular groove is smaller than the outer diameter of the damping ring. The damping ring engages with the annular groove.

[0008] Furthermore, an elastic element is provided at the other end of the sliding rod. When the bolt is rotated out of the rotating rod, the elastic element can drive the sliding rod to move in the direction of the bolt.

[0009] Furthermore, the elastic element includes a spring, the rotating rod has a groove along its length, the sliding rod is rotatably connected in the groove, and the two ends of the spring are respectively fixedly connected to the other end of the sliding rod and the groove wall.

[0010] Furthermore, the transmission assembly includes a rotating shaft, one end of which is fixedly connected to one side of the assembly block. A gear is rotatably connected inside the frame and is fixedly sleeved on the rotating shaft. A threaded section is provided on the rotating rod. A slider is horizontally slidably connected inside the frame and is screwed to the threaded section. A rack that meshes with the gear is provided at the top of the slider.

[0011] Furthermore, a guide rod is horizontally provided inside the frame, and the slider is slidably sleeved on the guide rod.

[0012] Furthermore, the damping ring is made of rubber, and the end of the damping ring near the annular groove is inclined.

[0013] Compared with the prior art, the beneficial effects provided by this utility model are as follows: the 360° rotatable gearbox assembly support platform has a rotatable handwheel that drives the assembly block to rotate through the transmission component, so as to facilitate the adjustment of the angle of the assembly block. After the angle is adjusted, the bolt can be turned to lock and fix the angle position of the rotating rod through the locking component, so as to avoid excessive load on the assembly block, which would cause the rotating rod to reverse and cause a safety accident. At the same time, it prevents the handwheel from being accidentally turned, and prevents the gearbox from slipping and falling, which would cause a safety accident. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-5 The present invention provides a technical solution for a 360° rotatable gearbox assembly platform, comprising a frame 1, a transmission assembly, bolts 3, and a locking assembly. An assembly block 5 is rotatably connected to one side of the frame 1, and a rotating rod 7 is rotatably connected inside the frame 1. A handwheel 2 is fixedly fitted onto one end of the rotating rod 7. When the handwheel 2 is rotated, the assembly block 5 is driven to rotate via the transmission assembly. Bolts 3 are screwed onto one end of the rotating rod 7. When bolts 3 are unscrewed from the rotating rod 7, the position of the rotating rod 7 can be locked and fixed by the locking assembly. Specifically, a crank handle 4 is detachably connected to the handwheel 2. The crank handle 4 facilitates the rotation of the handwheel 2, solving the problem of the handwheel 2 being difficult to rotate. Considering the long-term repetitive operation by the operator, the crank handle 4 reduces the discomfort to the operator's hands caused by repetitive operation, thus further improving convenience for the operator. The other end of the rotating rod 7 can also be equipped with a handwheel 2, bolts 3, and a locking assembly.

[0023] In this embodiment, the locking assembly includes a sliding rod 6 and a damping ring 9. One end of the sliding rod 6 near the handwheel 2 abuts against one end of the bolt 3. The sliding rod 6 is slidably connected within the rotating rod 7 along its length. Two connecting blocks 8 are symmetrically arranged on the sliding rod 6, and the ends of the two connecting blocks 8 that are far apart are fixedly connected to the inner wall of the damping ring 9. An annular groove 10 is formed in the frame 1. The outer diameter of the annular groove 10 is smaller than the outer diameter of the damping ring 9. The damping ring 9 is engaged with the annular groove 10. Specifically, an elastic element is provided at the other end of the sliding rod 6. When the bolt 3 is rotated out of the rotating rod 7, the elastic element can drive the sliding rod 6 toward the bolt 3. The direction of the movement is adjusted. After the angle of the rotating rod 7 is adjusted, the bolt 3 can be rotated. The bolt 3 is slowly unscrewed, and the elastic element pushes the sliding rod 6 to move in the direction of the bolt 3. At the same time, the sliding rod 6 drives the damping ring 9 to move towards the annular groove 10 through the two connecting blocks 8. The damping ring 9 gradually fits into the annular groove 10 to increase the rotational friction on the rotating rod 7. Since the outer diameter of the annular groove 10 is smaller than the outer diameter of the damping ring 9, the damping ring 9 will be squeezed and deformed during the process of fitting into the annular groove 10, thereby generating huge friction to lock the rotation angle of the rotating rod 7, so as to avoid excessive load on the assembly block 5, which would cause the rotating rod 7 to reverse and cause a safety accident.

[0024] In this embodiment, the elastic element includes a spring 17. A groove is formed in the rotating rod 7 along its length. The sliding rod 6 is rotatably connected in the groove. The two ends of the spring 17 are fixedly connected to the other end of the sliding rod 6 and the groove wall. Specifically, the size of the groove is adapted to the size of the sliding rod 6, and the cross-section of the groove is rectangular. The groove plays a guiding role, so that the sliding rod 6 can only move in a straight line along the length of the rotating rod 7. During the process of unscrewing the bolt 3, the damping ring 9 can be indirectly pushed into the annular groove 10 by the action of the spring 17, thereby generating a huge frictional force to lock the rotation angle of the rotating rod 7.

[0025] In this embodiment, the transmission assembly includes a rotating shaft 15, one end of which is fixedly connected to one side of the assembly block. A gear 14 is rotatably connected inside the frame 1 and is fixedly sleeved on the rotating shaft 15. A threaded section 16 is provided on the rotating rod 7. A slider 11 is horizontally slidably connected inside the frame 1 and is screwed to the threaded section 16. A rack 13 that meshes with the gear 14 is provided at the top of the slider 11. Specifically, rotating the handwheel 2 drives the rotating rod 7 to rotate, and the slider 11 is driven to slide horizontally along the length direction of the rotating rod 7 through the threaded section 16 of the rotating rod 7, indirectly driving the rack 13 to mesh with the gear 14, thereby driving the rotating shaft 15 to rotate, so as to realize the adjustment of the rotation angle of the assembly block.

[0026] More preferably, the transmission component can adopt a worm gear structure to achieve transmission. The worm gear itself has a self-locking function and will not cause the handwheel 2 to rotate in the opposite direction due to excessive load. However, during frequent operation by the operator, the handwheel 2 is easily accidentally touched and rotated, driving the assembly block 5 to rotate. The locking component mentioned above can still lock and fix the worm gear, preventing the handwheel 2 from being accidentally touched and rotated, and preventing the gearbox from slipping and falling, thus avoiding a safety accident.

[0027] In this embodiment, a guide rod 12 is horizontally provided inside the frame 1, and the slider 11 is slidably sleeved on the guide rod 12. Specifically, the guide rod 12 plays a guiding and limiting role, restricting the circumferential rotation of the slider 11, so that the slider 11 can only move linearly along the length direction of the rotating rod 7 under the helical transmission of the threaded section 16, so that the rack 13 and the gear 14 mesh more tightly.

[0028] In this embodiment, the damping ring 9 is made of rubber, and the end of the damping ring 9 near the annular groove 10 is inclined. Specifically, after the rubber undergoes a large deformation, it can almost completely return to its original shape. The damping ring 9 needs to be continuously compressed and rebounded, which continuously consumes energy. Although materials such as metal are hard, they lack this high elastic deformation ability, while materials such as clay consume energy, but the deformation is irreversible and will be permanently deformed. The rubber surface usually has a high coefficient of friction, which can effectively prevent relative sliding or displacement between the fastened parts, enhancing the stability and safety of the connection. The rubber is soft and can fill the tiny gaps between the annular groove 10 and the fitted parts well. This not only ensures uniform damping effect, but also plays a certain sealing role, preventing dust, moisture and other substances from entering. The inclined surface forms a natural guide, which can easily guide the damping ring 9 into the groove and guide it to slide smoothly into the correct position, greatly reducing the assembly difficulty and the risk of damage.

[0029] Working principle: The 360° rotatable gearbox assembly platform has a rotatable handwheel 2 that drives the rotating rod 7 to rotate. The threaded section 16 of the rotating rod 7 drives the slider 11 to slide horizontally along the length of the rotating rod 7, indirectly driving the rack 13 to mesh with the gear 14, driving the rotating shaft 15 to rotate. This allows for adjustment of the rotation angle of the assembly block. After adjustment, the bolt 3 can be unscrewed, and the spring 17 pushes the sliding rod 6 towards the bolt 3. At the same time, the sliding rod 6 drives the damping ring 9 towards the annular groove 10 through the two connecting blocks 8. The damping ring 9 gradually engages in the annular groove 10 to increase the rotational friction on the rotating rod 7. Since the outer diameter of the annular groove 10 is smaller than the outer diameter of the damping ring 9, the damping ring 9 will be squeezed and deformed during the engagement process, thereby generating a huge frictional force to lock the rotation angle of the rotating rod 7. This prevents the assembly block 5 from being overloaded, which could cause the rotating rod 7 to reverse and cause a safety accident. It also prevents the handwheel 2 from being accidentally turned and prevents the gearbox from slipping and falling, thus avoiding a safety accident.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
