Description
Technical Field
[0001] This utility model relates to the field of automotive gear processing and manufacturing technology, and in particular to a cooling and opening device for automotive gears. Background Technology
[0002] In the field of automotive gear manufacturing, gear drilling is a crucial process. During drilling, the cutting head of the drilling device rotates at high speed and experiences intense friction with the gear material, generating a large amount of heat. If this heat cannot be dissipated in time, the cutting head temperature will rise sharply. High temperatures not only reduce the hardness of the cutting head, accelerating its wear and deformation, shortening its service life, and increasing tool replacement costs, but also seriously affect the accuracy and quality of gear drilling, leading to problems such as dimensional deviations and substandard surface roughness in the machined gears. This, in turn, affects the performance and reliability of the entire automotive transmission system. To effectively reduce the cutting head temperature and ensure machining quality and cutting head life, cooling components are usually installed in the drilling device, using coolant to cool the cutting head.
[0003] During the circulation process, the coolant carries debris generated during the drilling process. This debris mainly includes metal chips and impurities generated during machining. As machining continues, the debris gradually accumulates at the filter in the coolant circulation system.
[0004] The existing cooling opening device for automotive gears has a relatively simple filter structure and lacks an effective debris removal mechanism. When debris accumulates to a certain extent, it will severely clog the filter plate. Once the filter plate is clogged, the flow of coolant will be greatly reduced, resulting in a decrease in flow rate. The reduced flow rate will prevent the coolant from circulating smoothly to the cutting head, so that the cutting head and gear cannot be cooled in a timely and effective manner. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cooling and opening device for automotive gears, which has the advantage of automatic cleaning. It solves the problem that the filter device in existing automotive gear cooling and opening devices has a relatively simple structure and lacks an effective debris cleaning mechanism. Once the filter plate is blocked, the flow rate of the cooling cutting fluid decreases, which prevents the coolant from circulating smoothly to the cutting head, thus preventing the cutting head and gear from being cooled in a timely and effective manner.
[0006] This utility model provides the following technical solution: a cooling opening device for automotive gears, comprising a base, a machine tool housing fixedly connected to the top surface of the base, a control center disposed on the surface of the machine tool housing, an opening device disposed inside the machine tool housing, a cooling component disposed on the side wall surface of the opening device, the cooling component including a holding cavity opened inside the base, a water pump disposed inside the base, a connecting hose fixedly connected to the output port of the water pump, a spray pipe fixedly connected to the end of the connecting hose away from the water pump, a filter assembly disposed inside the base, the filter assembly including a worktable fixedly connected to the top surface of the base, a first filter plate symmetrically fixedly connected to the bottom surface of the worktable, a fixing block fixedly connected to the center surface of the bottom of the worktable, and collection components disposed on both sides of the base.

The machine tool housing protects internal components such as opening devices, cooling components, and filtering components, preventing damage to internal parts from external factors. It also reduces noise during processing and the impact of coolant splashing on the surrounding environment. The control center provides an operating interface for operators to easily control and adjust various functions of the device.
[0007] Preferably: A second filter plate is fixedly connected to both sides of the fixed block; a first water-blocking strip is uniformly fixedly connected to the top surfaces of the first and second filter plates; a telescopic rod is symmetrically fixedly connected to the bottom surface of the fixed block; the telescopic rod is electrically connected to the control center; a mounting plate is fixedly connected to the output end of each telescopic rod; connecting blocks are fixedly connected to the top two ends of the mounting plate; a first brush plate is fixedly connected between the opposing surfaces of the two connecting blocks; guide grooves are formed on both sides of the top surface of the first filter plate; and the bottom surface of the mounting plate...

The second filter plate is fixedly connected to both sides of the fixed block, and the other end is fixedly connected to the inner wall surface of the holding cavity. It is set parallel to the first filter plate and further filters the coolant to ensure that the debris is effectively intercepted and improve the purity of the coolant.
[0008] Preferably, a collection hopper is fixedly connected between the inner walls of the base, and a connecting pipe is fixedly connected to the bottom center surface of the collection hopper. A flow sensor is provided on the inner wall surface of the connecting pipe. A first slag discharge port and a second slag discharge port are provided on both side walls of the base. The first slag discharge port and the second slag discharge port are used to discharge the debris swept to the slag discharge port by the first brush plate and the second brush plate to ensure the smooth flow of the filter plate.
[0009] Preferably, the collection assembly includes collection boxes disposed on both sides of the base, with handles fixedly connected to the top surface of the collection boxes, and collection openings provided on the side surface of the collection boxes near the base to ensure that debris can smoothly enter the collection boxes.
[0010] Preferably, the holding chamber is used to hold the cooling cutting fluid, the water pump is set inside the holding chamber, and the spraying end of the spray pipe forms a right angle with the cutting head in the opening device. This allows the cooling cutting fluid to be accurately sprayed onto the cutting head to cool it, reduce its temperature, prevent it from overheating and being damaged, and ensure machining quality and cutting head life.
[0011] Preferably, the base has an opening at the top, the first filter plate and the second filter plate are both arranged parallel to each other inside the holding cavity, the other ends of the first filter plate and the second filter plate are fixedly connected to the inner wall surface of the holding cavity, the telescopic rods are all arranged between the first filter plate and the second filter plate, the first brush plate and the second brush plate abut against the top surface of the corresponding first filter plate and the second filter plate, and the connecting blocks are all slidably connected inside the corresponding guide grooves. The guide grooves provide a track for the sliding of the connecting blocks, ensuring that the first brush plate can move in a predetermined direction and trajectory, thereby improving the cleaning effect.
[0012] Preferably, the collecting hopper is located below the second filter plate, and the first and second slag discharge ports are both connected to the interior of the holding chamber. The first and second slag discharge ports are both located at one end of the corresponding first and second filter plates. The flow sensor is electrically connected to the control center. The collecting hopper is used to collect the filtered cooling cutting fluid and gather it at the connecting pipe to facilitate the return and recycling of the coolant.
[0013] Preferably, the collection ports are all on the same horizontal line as the corresponding first and second slag discharge ports, and the collection box is made of a uniform transparent material. The transparent material of the collection box makes it easy for staff to observe the collection of debris inside the collection box and clean it in a timely manner.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. By setting the flow sensor, when the flow rate is abnormal, the control center controls the telescopic rod to start, so that the first and second brush plates sweep the debris to the first and second slag discharge ports, completing the automatic cleaning. This effectively avoids the filter plate clogging affecting the coolant circulation, prevents the water pump from running dry or blocked due to insufficient flow, ensures smooth coolant circulation, and ensures that the cooling effect is always stable. This keeps the cutting head of the hole-opening device at a suitable working temperature, improves processing accuracy and equipment reliability, and at the same time allows the telescopic rod to be started as needed, avoiding unnecessary energy consumption and mechanical wear.
[0016] 2. The filter assembly enables rapid separation of debris and coolant. The telescopic rod drives the brush plate to periodically clean the filter plate, pushing the debris to the discharge port. Combined with the collection box, the debris can be collected in a timely and effective manner.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 - Figure 3This utility model provides an embodiment of a cooling opening device for automotive gears, comprising a base 1, a machine tool housing 2 fixedly connected to the top surface of the base 1, a control center 3 disposed on the surface of the machine tool housing 2, an opening device 4 disposed inside the machine tool housing 2, a cooling component 5 disposed on the side wall surface of the opening device 4, the cooling component 5 including a holding cavity 51 opened inside the base 1, a water pump 52 disposed inside the base 1, a connecting hose 53 fixedly connected to the output port of the water pump 52, a spray pipe 54 fixedly connected to the end of the connecting hose 53 away from the water pump 52, and a filter component 6 disposed inside the base 1, the filter component 6 including a worktable 61 fixedly connected to the top surface of the base 1, the bottom surface of the worktable 61 being symmetrical A first filter plate 62 is fixedly connected. A fixing block 63 is fixedly connected to the center surface of the bottom of the workbench 61. Collection components 7 are provided on both sides of the base 1. A second filter plate 64 is fixedly connected to both sides of the fixing block 63. A first water-blocking strip 65 is evenly fixedly connected to the top surface of the first filter plate 62 and the second filter plate 64. A telescopic rod 66 is symmetrically fixedly connected to the bottom surface of the fixing block 63. The telescopic rod 66 is electrically connected to the control center 3. A mounting plate 67 is fixedly connected to the output end of the telescopic rod 66. A connecting block 68 is fixedly connected to both ends of the top surface of the mounting plate 67. A first brush plate 69 is fixedly connected between the opposite surfaces of the two connecting blocks 68. Guides are provided on both sides of the top surface of the first filter plate 62. A second brush plate 611 is fixedly connected to the bottom surface of the groove 610 and the mounting plate 67. A collection hopper 612 is fixedly connected between the inner walls of the base 1. A connecting pipe 613 is fixedly connected to the bottom center surface of the collection hopper 612. A flow sensor 614 is installed on the inner wall surface of the connecting pipe 613. A first slag discharge port 615 and a second slag discharge port 616 are opened on the two side walls of the base 1. The flow sensor 614 equipped with the device can monitor the flow data of the coolant in real time and feed the information back to the control center 3. When the flow is abnormal, such as when the first filter plate 62 and the second filter plate 64 are blocked due to debris accumulation, resulting in a reduction in the amount of coolant passing through and a decrease in flow, the control center 3 can accurately identify this situation and... The telescopic rod 66 is quickly activated, causing the mounting plate 67 to move. This, in turn, moves the first brush plate 69 and the second brush plate 611 onto the corresponding first filter plate 62 and second filter plate 64, sweeping debris to the first slag discharge port 615 and the second slag discharge port 616, completing the automatic cleaning process. This intelligent monitoring and automatic cleaning mechanism effectively prevents filter plate blockage from affecting coolant circulation, prevents water pump 52 from running dry or becoming blocked due to insufficient flow, ensures smooth coolant circulation, and maintains a stable cooling effect. This keeps the cutting head of the opening device 4 at a suitable working temperature, improving processing accuracy and equipment reliability. Simultaneously, it allows the telescopic rod 66 to be activated as needed, avoiding unnecessary energy consumption and mechanical wear. The control center 3 is responsible for receiving signals from various sensors, such as flow data from the flow sensor 614.The system analyzes and processes data according to a preset program and algorithm. Based on the analysis results, it controls the actions of various actuators, such as starting and stopping the water pump 52 and extending and retracting the telescopic rod 66, to achieve automated control of the device and ensure stable operation according to predetermined requirements. The drilling device 4 is used for drilling holes in automotive gears. Its cutting head cuts the gear material during high-speed rotation to machine the gear hole. A large amount of heat is generated during the machining process, requiring cooling component 5 to cool it and ensure machining quality and cutting head life. The holding cavity 51 is located inside the base 1 and stores cooling cutting fluid to provide sufficient cooling medium for the cooling process.
[0023] Please see Figure 1 - Figure 3 The collection assembly 7 includes collection boxes 71 disposed on both sides of the base 1. A handle 72 is fixedly connected to the top surface of each collection box 71. Collection ports 73 are opened on the side of each collection box 71 closest to the base 1. A holding chamber 51 is used to hold the cooling cutting fluid. A water pump 52 is disposed inside the holding chamber 51. The spraying end of the spray pipe 54 forms a right angle with the cutting head in the opening device 4. The top of the base 1 is open. A first filter plate 62 and a second filter plate 64 are both disposed parallel to each other inside the holding chamber 51. The other... One end of each filter is fixedly connected to the inner wall surface of the holding cavity 51. Telescopic rods 66 are all positioned between the first filter plate 62 and the second filter plate 64. The first brush plate 69 and the second brush plate 611 abut against the top surfaces of the corresponding first filter plate 62 and second filter plate 64. Connecting blocks 68 are slidably connected inside the corresponding guide grooves 610. A collecting hopper 612 is positioned below the second filter plate 64. The first slag discharge port 615 and the second slag discharge port 616 are both interconnected with the interior of the holding cavity 51. Each of the 16 filters is located at one end of the corresponding first filter plate 62 and second filter plate 64. The flow sensor 614 is electrically connected to the control center 3. The collection ports 73 are all on the same horizontal line as the corresponding first slag discharge ports 615 and second slag discharge ports 616. The collection box 71 is made of uniform transparent material. The parallel arrangement of the first filter plate 62 and second filter plate 64 in the filter assembly 6, as well as the stable connection with the worktable 61 and the inner wall of the holding cavity 51, constitutes a highly efficient chip separation structure. When the cooling cutting fluid carries the chips generated by the openings and falls down, the chips are... The debris is blocked on the filter plate, while the coolant flows smoothly into the holding chamber 51, achieving rapid separation of debris and coolant. The telescopic rod 66 drives the brush plate to clean the filter plate periodically, pushing the debris to the slag discharge port. Combined with the collection function of the collection box 71, the debris can be collected in a timely and effective manner. This not only avoids the accumulation of debris inside the device, keeping the working environment clean and reducing processing failures caused by debris interference, but also saves the trouble of frequent manual cleaning of debris, greatly improving production efficiency and making the production process more continuous and efficient.
[0024] Working principle: During the machining of automotive gears, the control center 3 activates the drilling device 4 to drill holes in the gear placed on the worktable 61. Simultaneously, the control center 3 controls the water pump 52 to operate, drawing coolant from the holding chamber 51. The coolant is then transported via the connecting hose 53 to the spray pipe 54, which sprays it at a right angle onto the cutting head of the drilling device 4 to cool it. The sprayed coolant, carrying debris generated during drilling, falls through the opening at the top of the base 1 onto the worktable 61. The mixture of coolant and debris then flows towards the bottom of the worktable 61, where it is symmetrically fixed. The first filter plate 62 is fixedly connected to the fixing block 63 at the bottom center of the worktable 61, and the second filter plates 64 are fixedly connected to both sides of the fixing block 63. The first water-blocking strips 65 are evenly fixedly connected to the top of the first filter plate 62 and the second filter plate 64, which play a role in buffering and guiding the flow of the mixture. The mixture is filtered on the first filter plate 62 and the second filter plate 64. Debris is blocked on the first filter plate 62 and the second filter plate 64, while the coolant flows into the holding chamber 51 through the first filter plate 62 and the second filter plate 64. At the same time, the flow sensor 614 monitors in real time the flow of the coolant collected by the collection hopper 612 and flowing back to the holding chamber 51 through the connecting pipe 613. The flow rate of the cooling cutting fluid is controlled and transmitted to the control center 3. When the flow rate is abnormal, the control center 3 controls the telescopic rod 66 to start. The output end of the telescopic rod 66 drives the mounting plate 67 to move. The mounting plate 67 drives the connecting blocks 68 fixed at both ends of its top to slide in the guide grooves 610 opened on both sides of the top of the first filter plate 62. The first brush plate 69 fixedly connected between the connecting blocks 68 at both ends of the top of the mounting plate 67 cleans the debris on the first filter plate 62 during the movement, cleaning the debris to the first slag discharge port 615. The second brush plate 611 fixedly connected to the bottom of the mounting plate 67 cleans the second filter plate 62 during the movement. The debris on the filter plate 64 is swept to the second slag discharge port 616. Since the collection port 73 on the surface of the collection box 71 near the base 1 is on the same horizontal line as the corresponding first slag discharge port 615 and second slag discharge port 616, the debris swept to the first slag discharge port 615 and second slag discharge port 616 enters the collection box 71. The handle 72 fixedly connected to the top of the collection box 71 makes it convenient for the staff to move and handle the collection box 71 so as to clean the debris in time. The transparent collection box 71 makes it easy for the staff to observe the debris collection inside, thereby ensuring the continuous and stable operation of the entire automotive gear cooling opening device.
