Description

Technical Field

[0001] This utility model relates to the field of crankcase processing, specifically to a crankcase body processing equipment. Background Technology

[0002] As the core load-bearing component of an internal combustion engine, the crankcase requires the machining of a large number of precision holes for installing bearings, oil passages, and fixed connecting parts. The accuracy of the hole positions and the surface quality directly determine the assembly accuracy and operational reliability of the engine. With the increasing demands for engine power performance and durability from industries such as automobiles and construction machinery, crankcases are mostly made of high-strength aluminum alloys or wear-resistant cast iron. During the drilling process, an efficient cutting and cooling system must be matched to ensure the machining quality.

[0003] Existing crankcase drilling equipment still has significant technical defects in the chip removal process, which seriously restricts processing stability and production efficiency: due to the complex structure of the crankcase hole system, which includes multiple deep holes, intersecting holes and stepped holes, the chip generated during drilling has a variety of shapes, leading to blockage of the chip removal channel. Utility Model Content

[0004] The present invention aims to provide a crankcase machining equipment to solve the problem of easy blockage of the chip removal channel in crankcase drilling equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crankcase machining equipment includes a frame, a worktable on the frame, a chip removal pool on the worktable, a tooling assembly for installing the crankcase body above the chip removal pool, a drill bit for drilling above the frame on the worktable, and a collection cylinder vertically arranged at the outlet of the chip removal pool; the collection cylinder passes through the chip removal pool, and a chip removal shell is arranged below the frame on the worktable, the chip removal shell including an inclined flow cylinder and a chip removal hood, an opening above the end of the inclined flow cylinder away from the chip removal hood and a filter plate below it, the filter plate passing through the collection cylinder, and the chip removal hood located outside the frame; a discharge port is opened on the side wall of the collection cylinder at the outlet of the chip removal pool, and a flow-limiting cylinder is vertically slidably connected above the collection cylinder, the side wall of the flow-limiting cylinder being tangent to the side wall of the collection cylinder for sealing the discharge port.

[0006] The beneficial effects of this solution are as follows: During the drilling process of the crankcase body, the equipment continuously sprays coolant onto the drilling location of the drill bit. The coolant can prevent the drill bit temperature from becoming too high. In addition, the coolant can flush away the debris generated during drilling and make it fall into the chip removal pool. Finally, the debris is carried along to the outlet of the chip removal pool. Since the flow restrictor seals the outlet under its own gravity, a large amount of debris and coolant accumulates at the outlet. When the coolant and debris accumulate to a certain extent, the flow restrictor is pulled upward. At this time, the outlet opens, and a large amount of coolant carries a large amount of debris out of the outlet. Under the action of the potential energy of the large amount of coolant, the debris is flushed down by the coolant, thus preventing debris blockage and improving chip removal efficiency.

[0007] In addition, since the tooling components are directly installed in the chip removal pool, and the crankcase body will vibrate during the drilling process, the vibration will be transmitted to the chip removal shell through the chip removal pool, thus further preventing the accumulation of chips in the chip removal shell.

[0008] Preferably, as an improvement, the chip discharge tank includes several inclined plates that are inclinedly connected to the bottom end of the workbench, and the inclined plates are provided with support plates for installing tooling components.

[0009] The beneficial effects are: the support plate transmits the vibration of drilling to the inclined plate. This direct connection with the tooling assembly can efficiently utilize the energy in the process, without the need to install other input devices to shake the chip shell, thus saving costs.

[0010] Preferably, as an improvement, the tooling assembly includes a horizontal mounting base and a positioning plate vertically disposed on the mounting base. The positioning plate is used to fix the crankcase body, and the mounting base is mounted on the top of the support plate.

[0011] Preferably, as an improvement, the workbench has a first reserved opening for tooling components to pass through and a second reserved opening for flow restrictor to pass through, and reinforcing ribs are provided between the support plate and the inclined plate.

[0012] The beneficial effects are as follows: the setting of the first reserved opening prevents the tooling components from directly contacting the worktable. Since the worktable is directly connected to the steel frame of the machine frame, it will weaken the vibration effect. Therefore, this design can effectively utilize the energy generated in the process. The setting of the reinforcing ribs can ensure that the crankcase body can be stably installed when utilizing the potential energy of process vibration.

[0013] Preferably, as an improvement, both the collecting cylinder and the flow-limiting cylinder have rectangular cross-sections, and the height of the flow-limiting cylinder is greater than the height from the top of the collecting cylinder to the outlet of the chip discharge pool.

[0014] Preferably, as an improvement, the top of the flow-limiting cylinder is provided with a top plate, which is transparent and has a rectangular cross-section, with a size larger than that of the collecting cylinder.

[0015] Preferably, as an improvement, the inner wall of the collecting cylinder is provided with a slider, and the outer wall of the flow limiting cylinder is provided with a groove for the slider to slide.

[0016] Preferably, as an improvement, the workbench is also provided with a third reserved opening for debris to fall off. Attached Figure Description

Detailed Implementation

[0018] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: frame 1, workbench 11, chip removal pool 12, inclined plate 121, support plate 1211, drill bit 13, first reserved opening 14, second reserved opening 15, third reserved opening 16, tooling assembly 2, mounting base 21, positioning plate 22, collection cylinder 3, discharge port 31, chip removal shell 4, inclined flow cylinder 41, filter plate 411, chip removal hood 42, flow limiting cylinder 5, top plate 51, crankcase body 6.

[0019] Example like Figures 1-4 The crankshaft housing machining equipment shown includes a frame 1, a worktable 11 on the frame 1, a drill bit 13 for drilling positioned above the worktable 11 on the frame 1, and a chip removal basin 12 on the worktable 11. The chip removal basin 12 includes four inclined plates 121 inclinedly connected to the bottom of the worktable 11, including two plates at the front and rear ends and two plates at the left and right ends of the worktable 11. The top ends of the inclined plates 121 are horizontally folded and fixed to the bottom of the worktable 11 with bolts. The sides of the four inclined plates 121 are welded together. An outlet is provided at the bottom. A support plate 1211 is vertically welded to the inclined plate 121 in the left and right directions. The support plate 1211 forms a frame. The top of the support plate 1211 is used to set the tooling assembly 2. The tooling assembly 2 includes a horizontal mounting base 21 and a positioning plate 22 vertically set on the mounting base 21. The positioning plate 22 is used to fix the crankcase body 6. The mounting base 21 is installed on the top of the support plate 1211. The worktable 11 has a first reserved opening 14 for the tooling assembly 2 to pass through. A reinforcing rib is provided between the support plate 1211 and the inclined plate 121.

[0020] For example, 2- Figure 5As shown in the figure, a collecting cylinder 3 is vertically installed at the outlet of the chip removal tank 12. The collecting cylinder 3 has a rectangular cross-section. The outlet of the chip removal tank 12 is also rectangular and fits against the outer wall of the collecting cylinder 3. The collecting cylinder 3 is welded to the outlet of the chip removal tank 12 and extends through the chip removal tank 12. A discharge port 31 is opened on the side wall of the collecting cylinder 3 at the outlet of the chip removal tank 12. The discharge port 31 is located inside the chip removal tank 12. A flow-limiting cylinder 5 is vertically slidably connected above the collecting cylinder 3. The side wall of the flow-limiting cylinder 5 is tangent to the side wall of the collecting cylinder 3. A slider is provided on the inner wall of the collecting cylinder 3. A groove for the slider to slide is opened on the outer wall of the flow-limiting cylinder 5. The groove extends longitudinally through the outer wall of the flow-limiting cylinder 5, and the bottom end of the groove is closed to ensure that the flow-limiting cylinder 5 and the collecting cylinder 3 always maintain a sliding connection and will not slip off. This is used to seal the discharge port 31. The cross-section of the flow-limiting cylinder 5 is also rectangular and restricts the flow. The height of the cylinder 5 is greater than the height from the top of the collecting cylinder 3 to the outlet of the chip removal pool 12. The top of the flow-limiting cylinder 5 is provided with a top plate 51, which is transparent and has a rectangular cross-section. Its size is larger than that of the collecting cylinder 3. The workbench 11 has a second reserved opening 15 for the flow-limiting cylinder 5 to pass through. In addition, the workbench 11 also has a third reserved opening 16 for the debris to fall. The frame 1 is provided with a chip removal shell 4 below the workbench 11. The chip removal shell 4 includes an inclined flow cylinder 41 and a chip removal cover 42. The inclined flow cylinder 41 has an opening at the top and a filter plate 411 at the bottom. The filter plate 411 passes through the collecting cylinder 3. The side wall of the collecting cylinder 3 below the chip removal pool 12 has an opening for the inclined flow cylinder 41 to pass through, and is welded to the side wall of the inclined flow cylinder 41 at the opening. The chip removal cover 42 is located outside the frame 1.

[0021] The specific implementation process is as follows: During the drilling process of the crankcase body 6, the equipment continuously sprays coolant onto the drilling position of the drill bit 13. The coolant can prevent the drill bit 13 from overheating. In addition, the coolant can flush away the debris generated during drilling and make it fall into the chip removal pool 12. Finally, the debris is carried along to the outlet of the chip removal pool 12. Since the flow restrictor 5 seals the discharge port 31 under its own gravity, a large amount of debris and coolant accumulates at the discharge port 31. When the coolant and debris accumulate to a certain extent, it is lifted upwards. Pull the flow restrictor 5, at which point the drain port 31 opens, and a large amount of coolant carries a large amount of debris out of the drain port 31. Under the action of the potential energy of the large amount of coolant, the debris is washed down by the coolant, so it will not cause debris blockage and improve the chip removal efficiency. The debris slides through the filter plate 411 to the chip removal cover 42, and the coolant continues to be collected downward into the collection cylinder 3 for recycling. At the same time, the crankcase body 6 will vibrate during the drilling process, and the vibration will be transmitted to the chip removal shell 4 through the chip removal pool 12, which can prevent debris blockage.
