Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine assembly technology, specifically to an engine housing positioning and assembly platform. Background Technology
[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), 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 (e.g., gasoline engine, aircraft engine).
[0003] For example, publication number CN222768392U, publication date April 18, 2025, titled "An Engine Assembly Workbench," includes a base, with an assembly platform welded to the upper end of the base. The inner wall of the assembly platform is equipped with a disassembly frame, and a sorting box is mounted on the upper end of the disassembly frame. This utility model uses the assembly platform to engage and fix the sorting box. When using the device, the assembly platform and sorting box facilitate the categorization and placement of assembly parts, increasing the device's usability. The assembly platform also engages and fixes the disassembly frame, allowing for quick replacement of the sorting box and easy placement according to usage habits, further enhancing usability. Finally, the rotating bead on the assembly platform allows for rotation of the placement platform, facilitating adjustment of the assembly angle and increasing usability.
[0004] In existing technologies, such as those containing the aforementioned patents, multiple positioning rods are fixedly connected to the platform. During assembly, the engine housing is usually lifted by a hoisting mechanism and then manually lowered slowly to align the positioning holes on the engine housing with the positioning rods on the platform. However, this method requires high positioning accuracy and can easily scratch the paint on the engine housing. In addition, the positioning process takes a relatively long time. Utility Model Content
[0005] The purpose of this invention is to provide a platform for positioning and assembling engine housings, so as to overcome the shortcomings of the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a platform for positioning and assembling an engine housing, comprising:
[0007] frame;
[0008] The support platform is rotatably connected to the frame;
[0009] The positioning mechanism includes a rotating disk rotatably connected to a support platform, a plurality of sliding rods slidably connected to the rotating disk, a positioning rod fixedly connected to each sliding rod, the end of each positioning rod penetrating and extending to the outside of the support platform and slidingly abutting against the support platform, and an elastic element provided between each positioning rod and the rotating disk.
[0010] The drive mechanism includes a worm gear fixedly connected to a rotating disk, a worm rotatably connected to a frame, the worm gear meshing with the worm, and a handwheel fixedly connected to the worm.
[0011] Furthermore, the support platform has multiple through slots, and each positioning rod is slidably connected in each through slot.
[0012] Furthermore, the through-slot is opened in an arc shape.
[0013] Furthermore, the elastic element is a compression spring.
[0014] Furthermore, each positioning rod has a rubber pad fixedly connected to its top.
[0015] Furthermore, a drive source is fixedly connected to the frame, and the output end of the drive source is fixedly connected to the rotating disk.
[0016] Compared with the prior art, the engine housing positioning and assembly platform provided by this utility model, by setting up a positioning mechanism and a driving mechanism, has a positioning stroke and a rotation stroke in sequence during the process of the driving mechanism driving the rotating disk to rotate. During the positioning stroke, the positioning rods are driven to insert into the positioning holes of the engine housing to achieve the positioning of the engine housing, which greatly shortens the positioning time. During the rotation stroke, the supporting platform is driven to rotate, thereby driving the engine housing to rotate, so as to facilitate the assembly of the engine housing at various positions, avoiding the need for assembly personnel to walk back and forth around the engine housing, and improving the assembly efficiency.

[0023] 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.
[0024] Please see Figure 1-4 The present invention provides an engine housing positioning and assembly platform, comprising: a frame 1; and a support platform 2 rotatably connected to the frame 1; it is understood that the engine housing is placed on the support platform 2 during assembly.
[0025] The positioning mechanism 3 has a positioning stroke and a rotation stroke. During the positioning stroke, it drives each positioning rod 32 to rotate around the axis of the support platform 2 and insert it into the positioning hole of the engine housing to achieve positioning of the engine housing. During the rotation stroke, the rotation of the rotating disk 31 and the insertion and cooperation of the positioning rod 32 with the positioning hole drive the support platform 2 to rotate synchronously, thereby achieving the purpose of rotating the engine housing. This allows for rotation of the engine housing at various positions, avoiding the need for assembly personnel to move back and forth around the engine housing for assembly, and improving the assembly efficiency of the engine to a certain extent.
[0026] Specifically, it includes a rotating disk 31 rotatably connected to the support platform 2, and multiple sliding rods 33 slidably connected to the rotating disk 31; wherein, the rotating disk 31 has through holes for sliding connection of the sliding rods 33; the sliding rods 33 slide in a direction parallel to the axis of the rotating disk 31; each sliding rod 33 is fixedly connected to a positioning rod 32; the positioning rod 32 is inserted into the positioning hole of the engine; the end of each positioning rod 32 penetrates and extends to the outside of the support platform 2, and slides against the support platform 2 respectively; an elastic element 34 is provided between each positioning rod 32 and the rotating disk 31; specifically, the elastic element 34 is a compression spring; more specifically, the process of elastic deformation of the elastic element 34 drives the positioning rod 32 to abut against the bottom surface of the engine; the process of the elastic element 34 restoring its elastic deformation drives the positioning rod 32 to insert into the positioning hole of the engine housing.
[0027] Specifically, the connection between the positioning rod 32 and the bearing platform 2 is as follows: multiple through slots 21 are provided on the bearing platform 2, and each positioning rod 32 is slidably connected in each through slot 21 in a corresponding manner; the through slots 21 are arc-shaped; the through slots 21 are centered on the axis of the bearing platform 2.
[0028] Preferably, in this embodiment, the drive mechanism 4 includes a worm gear 41 fixedly connected to the rotating disk 31, a worm 42 rotatably connected to the frame 1, the worm gear 41 meshing with the worm 42, and a handwheel 43 fixedly connected to the worm 42; by rotating the handwheel 43, the worm 42 is driven to rotate, and the meshing of the worm gear 41 and the worm 42 drives the rotating disk 31 to rotate synchronously, thereby completing the positioning stroke and the rotation stroke.
[0029] In another embodiment, another method of driving the rotating disk 31 to rotate is provided: a drive source is fixedly connected to the frame 1, and the output end of the drive source is fixedly connected to the rotating disk 31; the drive source is a motor.
[0030] Preferably, a rubber pad is fixedly connected to the top of each positioning rod 32; the rubber pad can prevent scratching the paint on the engine housing when the positioning rod 32 abuts against the bottom surface of the engine housing.
[0031] Working principle: In use, the engine housing is placed on the support platform 2. Under the gravity of the engine housing, the positioning rod 32 is driven to retract into the through groove 21 and press the elastic element 34. At this time, the handwheel 43 is turned, which drives the worm gear 42, worm wheel 41 and rotating disk 31 to rotate synchronously. During the rotation of the rotating disk 31, the positioning rod 32 is moved synchronously first, so that the positioning rod 32 slides in the through groove 21. As the sliding continues, when the positioning rod 32 is in the position corresponding to the positioning hole of the engine housing, the elastic element 34 is reset, driving the positioning rod 32 to insert into the positioning hole of the engine housing, thereby positioning the engine housing. At this time, the rotating disk 31 continues to rotate. Since the positioning rod 32 is in the insertion state with the positioning hole of the engine housing, it will drive the support platform 2 to rotate synchronously, thereby driving the engine housing to rotate and assemble the engine in various positions.
[0032] 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.
