Description

Technical Field

[0001] This utility model relates to the field of engine dismantling technology, specifically to a dismantling workbench for scrapped automobile engines. Background Technology

[0002] Scrapped vehicles refer to motor vehicles that have reached the national scrapping standards, or those that, although not reaching the national scrapping standards, have severely damaged engines or chassis, and fail to meet the national motor vehicle operation safety technical conditions or the national motor vehicle pollutant emission standards after inspection. With economic development and the improvement of people's living standards, the car purchase rate has gradually increased, and the replacement and elimination of motor vehicles has become the norm. Due to various reasons, there has been a significant increase in abandoned motor vehicles that have been left unused for a long time and occupy public resources. These vehicles that have not been moved for a long time, have been unused, or even unclaimed are called "zombie cars." Many "zombie cars" are in extremely poor condition, have very low residual value, and have a high probability of failure. They have almost no value for continued use and should be scrapped through the vehicle scrapping procedure according to regulations.

[0003] Chinese patent CN209467243U discloses a quick-clamping workbench for dismantling end-of-life car engines. A support plate is fixedly mounted on the base, and a top plate is fixed to the top of the support plate. A triangular plate is hinged between the support plates via a central shaft. A connecting sleeve is hinged to one apex of the triangular plate via a first pin, and the other end of the connecting sleeve is connected to the piston rod of a cylinder that provides clamping power. A first connecting rod is hinged to the second apex of the triangular plate via a third pin, and the other end of the first connecting rod is hinged to a first clamping plate via a fourth pin. A second connecting rod is hinged to the third apex of the triangular plate via a fifth pin, and the other end of the second connecting rod is hinged to a second clamping plate via a sixth pin. This method enables rapid clamping and fixing of the engine, and also allows for rapid release of the engine for position adjustment, ultimately achieving rapid engine dismantling.

[0004] However, the above technical solution has the following shortcomings: When using two-sided clamps to hold and fix the engine, it is necessary to strictly ensure that the distance from the two end faces of the engine to the corresponding clamping surfaces of the clamps is completely consistent. If there is a deviation in the distance on both sides, gaps will appear in the clamping, causing the engine to shift or shake during disassembly. This will not only affect the accuracy of disassembly processes such as bolt removal and component separation, but may also cause safety hazards such as parts falling or tools colliding. Only by ensuring that the distance between the two sides of the engine and the clamps is absolutely equal can the two-sided clamps make synchronous contact with the engine, ensuring that the clamping force is symmetrically distributed along the engine's central axis, thereby achieving stable and reliable clamping of the engine and providing a basic guarantee for subsequent efficient and safe disassembly operations. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a workbench for dismantling scrapped car engines.

[0006] The technical solution of this utility model: a dismantling workbench for scrapped automobile engines, comprising: The mounting base has a mounting cylinder on its top, and the bottom of the mounting cylinder is rotatably connected to the top of the mounting base. The support plate is mounted on the mounting cylinder and is slidably mounted on the mounting cylinder. Limit plates are slidably mounted on both sides of the top of the support plate. An adjustment mechanism is installed inside the mounting cylinder. One end of the adjustment mechanism passes through the mounting cylinder and the bearing plate. The adjustment mechanism is connected to the limiting plate to adjust the distance between the two sets of limiting plates. The reset mechanism is provided in two sets. The reset mechanism is installed inside the mounting cylinder, and one end of the reset mechanism is connected to the bearing plate. A rotating mechanism is installed inside the mounting base, with one end of the rotating mechanism connected to the mounting cylinder to drive the mounting cylinder to rotate.

[0007] Preferably, the adjusting mechanism includes a bidirectional threaded rod, a threaded sleeve, and a connecting frame; one end of the bidirectional threaded rod is rotatably disposed inside the mounting cylinder, and the other end of the bidirectional threaded rod passes through the mounting cylinder and extends to the outside of the mounting cylinder; two sets of threaded sleeves are provided, each of which is disposed inside the mounting cylinder and threadedly connected to the bidirectional threaded rod; two sets of connecting frames are provided, each corresponding to one of the threaded sleeves; one end of the connecting frame is disposed inside the mounting cylinder and fixedly connected to the threaded sleeve, and the other end of the connecting frame extends to the outside of the mounting cylinder and is fixedly connected to the limiting plate.

[0008] Preferably, the mounting cylinder is provided with multiple bellows, each of which is sleeved on the outside of the bidirectional threaded rod to protect the bidirectional threaded rod, and one end of the bellows is fixedly connected to the threaded sleeve.

[0009] Preferably, each set of reset mechanisms includes a connecting plate, a fixing plate, and a reset spring; one end of the connecting plate is fixedly connected to the bottom of the bearing plate, and the other end of the connecting plate passes through the mounting cylinder and extends into the mounting cylinder; two fixing plates are provided, both of which are set in the mounting cylinder; two sets of reset springs are provided and correspond one-to-one with the fixing plates; the reset springs are set inside the mounting cylinder.

[0010] Preferably, two fixing plates are respectively disposed on both sides of the connecting plate, the fixing plates are fixedly connected to the bottom of the inner wall of the mounting cylinder, one end of the return spring is connected to the fixing plate, and the other end of the return spring is fixedly connected to the connecting plate.

[0011] Preferably, the rotating mechanism includes a mounting shaft, an adjusting rod, an adjusting bevel gear, and an adjusting bevel gear ring; the mounting shaft is disposed within the mounting base, and its top end is fixedly connected to the bottom end of the mounting cylinder; one end of the adjusting rod is rotatably disposed within the mounting base, and the other end of the adjusting rod passes through the mounting cylinder and extends to the outside of the mounting cylinder; the adjusting bevel gear is disposed within the mounting base and is fixedly connected to the adjusting rod; the adjusting bevel gear ring is disposed within the mounting base and is fixedly connected to the mounting shaft; the adjusting bevel gear and the adjusting bevel gear ring mesh with each other.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: Compared to traditional clamping worktables that require strict alignment of the distance between the two sides of the engine, this utility model achieves adaptive clamping through an "adjustment mechanism + sliding design of the support plate". When the adjustment mechanism moves the two limit plates to approach the engine synchronously, if there is a positional deviation in the initial placement of the engine, the support plate can slide along the surface of the mounting cylinder to ensure that the two limit plates can make close contact with the engine surface, completely eliminating the clamping gap caused by the distance deviation, avoiding engine displacement and shaking during disassembly, ensuring the accuracy of bolt removal, component separation and other processes, and reducing the safety risks of parts falling and tools colliding.

[0017] Example 4; as Figure 2 As shown, the present invention discloses a scrapped car engine dismantling workbench. Compared with Embodiment 3, this embodiment also specifically discloses the structure of the rotating mechanism. The rotating mechanism includes a mounting shaft 51, an adjusting rod 52, an adjusting bevel gear 53, and an adjusting bevel gear ring 54. The mounting shaft 51 is disposed in the mounting base 1, and the top end of the mounting shaft 51 is fixedly connected to the bottom end of the mounting cylinder 2.

The double-threaded rod 31 is rotated, and the rotation of the double-threaded rod 31 drives the limiting plates 7 to move through the threaded sleeve 32 and the connecting bracket 33. The limiting plates 7 clamp and fix the engine from both sides. When the limiting plates 7 clamp and fix the engine from both sides, the engine drives the support plate 6 to slide on the surface of the mounting cylinder 2, so that the limiting plates 7 on both sides of the engine can effectively contact the engine, thereby ensuring that the limiting plates 7 effectively clamp and fix the engine. During the disassembly of the engine, in order to facilitate the disassembly operation, the direction of the engine is adjusted. The adjusting rod 52 is rotated to drive the adjusting bevel gear 53 to rotate together. The adjusting bevel gear 53 drives the adjusting bevel gear ring 54 and the mounting shaft 51 to rotate together through the meshing action. The rotation of the mounting shaft 51 drives the engine to rotate together through the mounting cylinder 2 and the support plate 6, adjusting the engine to a position that is convenient for disassembly. After the engine is disassembled, the double-threaded rod 31 is rotated in the opposite direction to open the limiting plates 7 on both sides of the engine, and the engine is removed from the support plate 6. The support plate 6 is reset under the action of the return spring 43.
