Description

Technical Field

[0001] This utility model relates to the field of transmission shaft processing technology, and in particular to a processing equipment for both end faces of an oil pump transmission shaft. Background Technology

[0002] As a key component of the engine lubrication system, the machining accuracy of the two end faces of the oil pump drive shaft directly affects the assembly clearance and transmission efficiency. During the machining process of the two end faces of the drive shaft, the accumulation and residue of debris on the machining table of the CNC lathe is a major problem affecting machining quality and production efficiency. Traditional equipment relies heavily on manual cleaning or fixed brush cleaning. Manual cleaning requires frequent machine stops, and residual debris can easily cause secondary scratches on the workpiece. Fixed brushes have a limited cleaning range, especially at the edges and corners of the processing table. Although some equipment is equipped with simple chip blowing devices, they have problems such as fixed airflow direction and insufficient coverage. The nozzle angle is not adjustable, so it can only blow away the central area of ​​the processing table, and the edge debris still needs to be cleaned manually. To address this, a machining device for both ends of the oil pump drive shaft is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing processing equipment, such as incomplete debris removal and low degree of automation, and to propose a processing equipment for both ends of an oil pump drive shaft.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A machining equipment for both ends of an oil pump drive shaft includes a support table and a CNC lathe. The bottom of the CNC lathe is provided with a machining table, and the CNC lathe is fixedly connected to the top of the support table. A cleaning mechanism, installed on one side of the machining table, is used to clean the debris generated during machining. The cleaning mechanism includes two fixed seats fixedly connected to one side of the machining table, two guide rods fixedly connected between the two fixed seats, and a lead screw rotatably connected between the two fixed seats. A motor is fixedly connected to one side of the fixed seats, and one end of the motor output shaft is fixed to the lead screw. A guide block slides through the outer circumference of the two guide rods. A sleeve is fixedly connected to the middle of the guide block, and the sleeve is threaded to the outer circumference of the lead screw. An exhaust chamber matching the surface of the machining table is fixedly connected to the top of the guide block. An air inlet pipe communicating with the exhaust chamber is fixedly connected to one side of the exhaust chamber. The air inlet pipe is connected to an external air source through a pipe. A scraper is fixedly connected to one side of the bottom of the exhaust chamber. Multiple nozzles are fixedly connected to the side wall of the exhaust chamber. One side of the exhaust chamber is in contact with one side of the CNC lathe tool holder. The chip collection mechanism is located on one side of the machining table to collect the chips generated during machining.

[0005] In one possible design, the chip collection mechanism includes a collection port on one side of the machining table, a suction box that is detachably inserted into the collection port, a suction pipe and a handle that are fixedly connected to one side of the suction box, the suction pipe being connected to an external negative pressure device through a pipe, and multiple suction holes being provided on the top of the machining table, the suction holes being vertically connected to the collection port.

[0006] In one possible design, the top of the suction box has a groove, the inside of the suction box contains a mesh bag, the top of the suction box is snapped with a removable sleeve that matches the groove, and the outer edge of the mesh bag is located in the gap between the groove and the sleeve.

[0007] In one possible design, the nozzle's airflow direction is obliquely towards the front end of the scraper.

[0008] In one possible design, the chip-facing surface of the scraper is an arc-shaped surface made of glass fiber reinforced resin.

[0009] In one possible design, baffles are fixedly connected to both sides of the top of the processing table.

[0010] In one possible design, a PLC controller is fixedly connected to one side of the machining table, and the PLC controller is electrically connected to the CNC lathe and the motor. In this application: The oil pump drive shaft to be processed is fixed by a fixture. After receiving the start signal, the PLC controller sends a processing instruction to the CNC lathe. The CNC lathe drives the tool on the tool holder to cut the end face of the drive shaft according to the preset program. During the machining process, the PLC controller receives the axial displacement signal of the CNC lathe tool holder in real time and sends control commands to the motor simultaneously, so that the cleaning mechanism follows the tool holder in axial displacement. The motor drives the lead screw to rotate according to the displacement signal. Through the cooperation of the sleeve and the guide block, the exhaust chamber moves along the guide rod at the same axial speed as the tool holder, ensuring that the exhaust chamber is in contact with one side of the tool holder and preventing chips from falling into the gap between the exhaust chamber and the tool holder. The external air source is introduced into the exhaust chamber through the air inlet pipe and sprays air obliquely towards the front end of the scraper from the nozzle, blowing the small chips scattered during the cutting process to one side. The scraper at the bottom of the exhaust chamber contacts the surface of the machining table. The arc surface of the chip-facing surface continues to push and scrape with the displacement action, scraping the chips that have not been blown away to one side. The chips near the suction hole fall into the hole and are cleaned out of the machining table. The baffle at the top of the machining table restrains the chips within the table area and prevents them from falling to the bottom of the equipment. When the CNC lathe finishes machining and returns to its initial position, it sends a completion signal to the PLC controller. The PLC controller immediately starts the motor, which moves the exhaust chamber. The exhaust chamber is then moved by blowing air through the nozzles and scraping with the scraper to send all the debris on the worktable to the suction port. The motor then reverses, moving the exhaust chamber back to its initial position. The debris pushed to one side of the processing table by the scraper and airflow enters the collection port through multiple suction holes on the top of the processing table under negative pressure. Since the suction holes and the collection port are vertically connected, the debris falls into the net bag inside the suction box through the collection port. The suction pipe is connected to an external negative pressure device to provide continuous power for the suction of debris. The edge of the net bag is clamped between the groove and the sleeve of the suction box. The net bag can be quickly removed by removing the sleeve during cleaning.

[0011] Beneficial effects: In this utility model, the oil pump drive shaft end face processing equipment, through the coordinated use of components such as scrapers, nozzles, baffles, and exhaust chambers, and the synchronous axial displacement design of the cleaning mechanism and the tool holder, ensures that the exhaust chamber is always in contact with one side of the tool holder, eliminating the risk of debris falling into the gap between the two. At the same time, the combined cleaning mode of scraper pushing and spraying with nozzle air blowing creates a synergistic effect. The arc-shaped surface of the scraper can smoothly push and scrape large pieces of debris, and the obliquely set nozzle can blow scattered small debris in the same direction. With the baffles on both sides of the processing table, it ensures that the debris generated during processing is effectively cleaned, greatly reducing the debris residue rate on the processing table. In this utility model, the oil pump drive shaft end face processing equipment uses a combination of PLC controller, CNC lathe, motor and other components. The PLC controller realizes the linkage of the entire process of processing and cleaning. During the processing, the PLC controller receives the tool seat movement signal in real time and synchronously controls the cleaning mechanism to follow the movement, realizing processing and cleaning at the same time. After the processing is completed, the cleaning mechanism is automatically driven to perform a second comprehensive cleaning of the table. Finally, it is reset to wait for the next cycle. The whole process does not require manual operation, which improves the degree of automation, reduces cleaning time and improves production efficiency. In this invention, the PLC controller controls the synchronous axial displacement design of the cleaning mechanism and the tool holder, ensuring that the exhaust chamber always fits against one side of the tool holder, eliminating the risk of debris falling into the gap between the two. At the same time, the combined cleaning mode of scraper pushing and nozzle blowing creates a synergistic effect to ensure that the debris generated during processing is effectively cleaned, greatly reducing the debris residue rate on the processing table.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one implementation case, refer to Figures 1-5 A machining equipment for both ends of a transmission shaft includes: a support table 1 and a CNC lathe 3. The bottom of the CNC lathe 3 is provided with a machining table 2. The CNC lathe 3 is fixedly connected to the top of the support table 1. The CNC lathe 3 drives the cutting tool on the tool holder according to a preset program to perform cutting machining on both ends of the transmission shaft. In this embodiment, a cleaning mechanism is installed on one side of the processing table 2 to clean the debris generated during processing. The cleaning mechanism includes two fixed seats 4 fixedly connected to one side of the processing table 2, two guide rods 9 fixedly connected between the two fixed seats 4, and a lead screw 10 rotatably connected between the two fixed seats 4. A motor 5 is fixedly connected to one side of the fixed seats 4, and one end of the output shaft of the motor 5 is fixed to the lead screw 10. A guide block 12 slides through the outer circumference of the two guide rods 9, and a sleeve 11 is fixedly connected to the middle of the guide block 12. The sleeve 11 and the lead screw 10 are connected to each other. The guide block 12 is fixedly connected to the top of the outer threaded connection and is matched with the surface of the processing table 2. An air inlet pipe 8 is fixedly connected to one side of the air inlet 7 and communicates with the air inlet 7. The air inlet pipe 8 is connected to an external air source through a pipe. A scraper 701 is fixedly connected to one side of the bottom of the air inlet 7. Multiple nozzles 702 are fixedly connected to the side wall of the air inlet 7. One side of the air inlet 7 is in contact with one side of the tool holder of the CNC lathe 3. Compressed air is introduced into the air inlet pipe 8 and distributed by the air inlet 7. It is then sprayed out by multiple obliquely arranged nozzles 702, which can blow iron chips toward the suction hole 201. In particular, a chip collection mechanism is provided on one side of the machining table 2 to collect the chips generated during machining of the surface of the machining table 2.

[0016] It should be noted that the chip collection mechanism includes a collection port 203 located on one side of the processing table 2. A vacuum box 13 is detachably inserted into the collection port 203. A vacuum pipe 15 and a handle 14 are fixedly connected to one side of the vacuum box 13. The handle 14 facilitates the insertion and removal of the vacuum box 13 by the operator. The vacuum pipe 15 is connected to an external negative pressure device through a pipe to provide suction, which facilitates the suction of chips into the vacuum box 13. Multiple suction holes 201 are provided on the top of the processing table 2. The suction holes 201 are vertically connected to the collection port 203.

[0017] This application can be used in the field of transmission shaft machining technology, or in other fields applicable to this application.

[0018] In another implementation case, refer to Figures 1-5 A machining device for both ends of an oil pump drive shaft is applied to the field of drive shaft machining technology. The top of the suction box 13 has a groove 1301. A mesh bag 17 is placed inside the suction box 13. The top of the suction box 13 is snapped with a detachable sleeve 16 that matches the groove 1301. The outer edge of the mesh bag 17 is located in the gap between the groove 1301 and the sleeve 16. The mesh bag 17 filters and collects iron filings to prevent the filings from entering the suction pipe 15 and clogging the pipe. The groove 1301 and the sleeve 16 clamp and fix the mesh bag 17 to prevent the mesh bag 17 from sliding into the suction box 13.

[0019] In this embodiment, the jet direction of the nozzle 702 is oblique to the front end of the scraper 701.

[0020] In particular, the chip-facing surface of the scraper 701 is an arc-shaped surface made of glass fiber reinforced resin. The arc-shaped surface of the scraper 701 reduces the scraping resistance and prevents iron chips from getting stuck. The glass fiber reinforced resin material of the scraper 701 will not scratch the processing table 2.

[0021] In addition, baffles 202 are fixedly connected to both sides of the top of the processing table 2 to constrain the debris generated during processing within the range of the processing table 2.

[0022] It should be noted that a PLC controller 6 is fixedly connected to one side of the machining table 2, and the PLC controller 6 is electrically connected to the CNC lathe 3 and the motor 5.

[0023] However, as is well known to those skilled in the art, the working principles and wiring methods of the CNC lathe 3, motor 5 and PLC controller 6 are all conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0024] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
