Description

Technical Field

[0001] This utility model relates to the technical field of automobile recycling, and in particular to a device for drilling and scrapping automobile engines. Background Technology

[0002] With the rapid development of the automotive industry, the recycling and disposal of end-of-life vehicles has become a global concern for environmental protection and resource recycling. As a core component of automobiles, engines, due to their content of heavy metals and high-value materials, are at risk of being illegally disassembled, refurbished, and resold in the used car market.

[0003] Currently, the industry commonly uses manual drilling to physically destroy end-of-life engines, achieving irreversible damage by penetrating key components such as the cylinder block and crankcase. However, this traditional manual operation method has significant drawbacks: operators must use heavy drilling equipment to drill holes in engines weighing hundreds of kilograms, resulting in high labor intensity and safety hazards such as slippage and injury. Manual drilling is prone to hole displacement due to fatigue, and a single engine typically requires 5 to 10 through holes at different angles to meet the end-of-life standard. Due to the large number of holes drilled, manual operation is inefficient and cannot meet the daily processing needs of hundreds of engines at large-scale recycling plants. Therefore, to address these shortcomings, this application proposes a drilling and end-of-life device for automobile engines. Utility Model Content

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figure 1 and Figure 2 As shown, a car engine drilling and scrapping device 10 includes a frame 100, a lifting assembly 200, and a drilling assembly 300. The frame 100 is used to support the car engine. The lifting assembly 200 includes a lifting plate 210, a screw shaft 220, a screw wheel 230, and a lifting drive component 240. The lifting plate 210 is slidably mounted on the frame 100 in a vertical direction. One end of the screw shaft 220 is mounted on the lifting plate 210, and the other end of the screw shaft 220 is slidably connected to the frame 100. The screw wheel 230 rotates... The screw wheel 230 is screwed to the screw shaft 220 and placed on the frame 100. The lifting drive 240 is set on the frame 100 and connected to the screw wheel 230. The drilling assembly 300 includes a drilling drive 310, a drill rod 320 and a drill bit 330. The drilling drive 310 is set on the lifting plate 210. The drill rod 320 is rotatably set inside the screw shaft 220. One end of the drill rod 320 is connected to the drilling drive 310 and the drill bit 330 is set on the other end of the drill rod 320.

[0030] It should be noted that the disassembled car engine is placed on the frame 100 using a crane, allowing the lifting assembly 200 to work with the drilling assembly 300 to drill holes in the engine. Specifically, the lifting plate 210 is slidably mounted on the frame 100 in a vertical direction. One end of the screw shaft 220 is fixedly mounted on the lifting plate 210, and the other end of the screw shaft 220 is slidably connected to the frame 100. External threads are formed on the outer wall of the screw shaft 220. The screw wheel 230 is rotatably mounted on the frame 100, and internal threads are formed on the screw wheel 230, which is screwed to the screw shaft 220. The lifting drive component 240 is mounted on the frame 100 and connected to the screw wheel 230. Thus, the lifting drive 240 drives the screw wheel 230 to rotate. Since the screw wheel 230 is screwed to the screw shaft 220, and the screw wheel 230 can only rotate relative to the frame 100 without sliding, the screw shaft 220 will move up and down relative to the frame 100, thereby causing the lifting plate 210 to move up and down. Further, the drilling drive 310 is mounted on the lifting plate 210. For example, the drilling drive 310 is a motor. The drill rod 320 is rotatably mounted inside the screw shaft 220, and the drill bit 330 is mounted at the bottom end of the drill rod 320. The drilling drive 310 drives the drill rod 320 to rotate, which in turn drives the drill bit 330 to rotate continuously. Thus, the lifting drive 240 drives the lifting plate 210 to descend, and the drilling drive 310, through the drill rod 320, drives the drill bit 330 to perform drilling. This automatically performs drilling operations on the car engine on the frame 100, thereby effectively improving the processing efficiency and safety of the car engine.

[0031] like Figure 1 As shown, in one embodiment, the frame 100 includes a frame body 110 and a carrier plate 120. The carrier plate 120 is disposed on the top of the frame body 110. The lifting plate 210 is slidably disposed on the carrier plate 120 in the vertical direction. The screw shaft 220 is slidably connected to the carrier plate 120. The screw wheel 230 is rotatably disposed on the carrier plate 120. The lifting drive component 240 is disposed on the carrier plate 120.

[0032] It should be noted that the carrier plate 120 spans above the frame 110, so that the lifting plate 210, screw shaft 220, screw wheel 230, and lifting drive component 240 are all connected to the carrier plate 120. In this way, the frame 110 supports the car engine, so that the lifting component 200 and the drilling component 300 cooperate to drill holes in the car engine for scrapping.

[0033] like Figure 1 As shown, in one embodiment, a plurality of rollers 130 are rotatably arranged on the frame 110.

[0034] It should be noted that each roller 130 is located at the bottom of the frame 110, and the rollers 130 are arranged in parallel. Thus, when a car engine is placed on the rollers 130, applying external force to the engine allows it to be moved along the rollers 130. Furthermore, in one embodiment, each roller 130 is connected to a chain driven by a motor. Thus, by reliably rotating each roller 130 using a motor, the car engine can be automatically loaded and unloaded on the frame 110, thereby improving the processing efficiency of drilled and scrapped car engines.

[0035] like Figure 1 As shown, in one embodiment, a plurality of guide rods 160 are provided on the carrier plate 120, and a top frame 170 is provided on the top of each guide rod 160, and each guide rod 160 passes through the lifting plate 210.

[0036] It should be noted that the above-described structure is provided on the carrier plate 120 to enable the lifting plate 210 to move stably relative to the carrier plate 120. Specifically, one end of each guide rod 160 is fixedly installed on the same side of the lifting plate 210 and the carrier plate 120, and the other end of each guide rod 160 is fixedly connected to the top frame 170, with the guide rods 160 spaced apart. Each guide rod 160 passes through the carrier plate 120. For example, a linear bearing is installed on the lifting plate 210, and the guide rods 160 are adapted to pass through the linear bearing, so that the lifting plate 210 can move stably relative to the carrier plate 120 through the guiding action of each guide rod 160.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, a guide sleeve 140 is provided on the carrier plate 120, and the screw shaft 220 is slidably disposed in the guide sleeve 140 along the axial direction.

[0038] It should be noted that, since the end of the screw shaft 220 away from the lifting plate 210 is suspended, in order to improve the stability of the screw shaft 220, this end is designed to be slidably connected to the carrier plate 120. Furthermore, since the outer wall of the screw shaft 220 has external threads, to avoid interference between the external threads and the carrier plate 120, a guide sleeve 140 is installed on the carrier plate 120, allowing the screw shaft 220 to reciprocate stably along the axial direction of the guide sleeve 140.

[0039] like Figure 3 and Figure 4 As shown, in one embodiment, a guide strip 141 is provided on the inner side wall of the guide sleeve 140 along the axial direction, and a guide groove 221 is provided on the outer side wall of the screw shaft 220 along the axial direction, and the guide strip 141 is adapted to slide in connection with the guide groove 221.

[0040] It should be noted that there are two or more guide strips 141 and guide grooves 221, with each guide strip 141 and guide groove 221 spaced apart. This allows the screw shaft 220 to slide axially within the guide sleeve 140 by sliding the guide strip 141 within the guide groove 221. Furthermore, it ensures that the external thread of the screw shaft 220 does not interfere with the inner wall of the guide sleeve 140. Additionally, it ensures that the screw wheel 230 can be stably screwed and fixed to the screw shaft 220.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, a fastener 150 is provided on the carrier plate 120, a screw shaft 220 passes through the fastener 150, a screw wheel 230 and a guide sleeve 140 are both located inside the fastener 150, and a thrust ball bearing 250 is provided on each of the axial sides of the screw wheel 230, one of the thrust ball bearings 250 abutting against the guide sleeve 140, and the other thrust ball bearing 250 abutting against the fastener 150.

[0042] It should be noted that the retaining seat 150 is fixedly mounted on the carrier plate 120, and the screw shaft 220 passes through the retaining seat 150, without any structural connection between the screw shaft 220 and the retaining seat 150. The screw wheel 230 is located inside the retaining seat 150, and two thrust ball bearings 250 are respectively sleeved on both axial sides of the screw wheel 230. In this way, the screw wheel 230 is axially limited. Regardless of whether the screw wheel 230 moves upward or downward along the axial direction of the screw shaft 220, the screw wheel 230 abuts against the retaining seat 150 or the guide sleeve 140 through the thrust ball bearings 250, ensuring that the screw wheel 230 is stable on the top of the carrier plate 120. However, under the action of the thrust ball bearings, the screw wheel 230 can also rotate stably relative to the carrier plate 120. Thus, when the lifting drive 240 drives the screw wheel 230 to rotate, since the height of the screw wheel 230 relative to the carrier plate 120 remains unchanged, the screw shaft 220 can move up and down, thereby enabling the lifting plate 210 to move up and down stably.

[0043] like Figure 1 As shown, in one embodiment, the lifting drive 240 includes a lifting motor 241 and a belt. The lifting motor 241 is mounted on the carrier plate 120, and the belt is connected to the output shaft of the lifting motor 241 and the pulley 230.

[0044] It should be noted that the lifting motor 241 is fixedly installed on the carrier plate 120, and a pulley is installed on the output shaft of the lifting motor 241. Then, the belt is respectively connected to the pulley and the screw wheel 230. In this way, the lifting motor 241 drives the screw wheel 230 to rotate through the belt.

[0045] like Figure 2As shown, in one embodiment, a ball bearing 260 is provided at each end of the screw shaft 220, and the drill rod 320 is rotatably connected to the two ball bearings 260.

[0046] It should be noted that in order to enable the drill pipe 320 to rotate stably relative to the screw shaft 220, two ball bearings 260 are coaxially installed inside the screw shaft 220, with the two ball bearings 260 located at both ends of the screw shaft 220 respectively, and the drill pipe 320 is adapted to be installed on the two ball bearings 260.

[0047] In one embodiment, the maximum diameter of the drill bit 330 is greater than the outer diameter of the screw shaft 220.

[0048] Thus, after the drill bit 330 drills a hole in the disassembled car engine and scraps it, the resulting through hole will definitely be larger than the screw shaft 220, allowing the screw shaft 220 to smoothly enter the car engine along the drill bit 330, avoiding interference or collision between the screw shaft 220 and the car engine.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
