Description

Technical Field

[0001] This utility model relates to the field of cooling, and more specifically, it relates to a cooling device for gear grinding in transmissions. Background Technology

[0002] Transmission gears are key components in a car's transmission (also known as a gearbox), used to adjust the efficiency and speed of power transmission from the engine to the wheels. Transmission gear grinding refers to the precision machining process of initially formed transmission gears, aiming to further improve their accuracy, surface quality, and overall performance. This process utilizes gear grinding machines.

[0003] Because the friction between gears and grinding wheels generates a lot of heat, gear grinding machines are equipped with cooling devices. Existing gear grinding machine cooling devices generally use air cooling, water cooling, oil cooling, and spray cooling. Each of these cooling methods has its advantages and disadvantages. Workers will choose the appropriate cooling method to assist in processing based on the gears being processed. However, if water-based cutting fluid and oil-based cutting fluid are mixed, emulsification will occur, which will reduce the cooling performance of the coolant and may also cause corrosion to the processed parts. Therefore, many gear grinding machines are only equipped with one type of coolant, either water cooling or oil cooling. When another cooling method is required, another machine is often used, which increases the processing limitations of gear grinding machines.

[0004] Based on the above, the purpose of this utility model is to provide a cooling device for gear grinding in a transmission to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a cooling device for gear grinding in transmissions. This invention supplies coolant and cooling oil through two sets of coolant supply mechanisms, which users can switch between using a four-way valve. It also includes two collection boxes to collect and reuse the coolant and cooling oil respectively, preventing them from mixing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gear grinding cooling device for transmission gears, comprising a gear grinding machine body, a flexible nozzle provided on the gear grinding machine body, a collection frame one fixedly connected to the gear grinding machine body, the collection frame one communicating with the processing chamber of the gear grinding machine body, a collection frame two slidably connected to the collection frame one, a drive mechanism for driving the collection frame two to move provided on the gear grinding machine body, two coolant supply mechanisms provided on the gear grinding machine body, each coolant supply mechanism comprising a storage tank fixedly connected to the gear grinding machine body, a filter box communicating with the storage tank, the two filter boxes communicating with the collection frame one and the collection frame two respectively, a four-way valve provided on the gear grinding machine body, the outlet of the four-way valve fixedly connected to the flexible nozzle, the three inlets of the four-way valve connected to the two storage tanks and an external high-pressure gas supply device respectively, and a delivery pump provided between the four-way valve and the two storage tanks.

[0007] By adopting the above technical solution, users can fill two storage tanks with coolant and cooling oil respectively, and then choose between air cooling, water cooling, or oil cooling depending on the gear processing requirements. The hose nozzle is then connected to an external high-pressure gas supply device, the coolant storage tank, or the cooling oil storage tank via a four-way valve. When using coolant for cooling, the delivery pump delivers coolant to the hose nozzle, and the first collection box collects the coolant. After filtration through the filter box, the coolant returns to the storage tank for recycling. When switching to cooling oil, the four-way valve switches the connection mode, and the drive mechanism moves the second collection box into the first collection box until the first collection box is covered by the second collection box. At this point, the second collection box collects the cooling oil, preventing the coolant and cooling oil from mixing. With this setup, the gear grinding machine has both coolant and cooling oil available for the user to choose from, and the two are less likely to mix, preventing a decrease in cooling effect due to emulsification.

[0008] The present invention is further configured such that: the driving mechanism includes a motor fixedly connected to the main body of the gear grinding machine; a lead screw is fixedly connected to one end of the output shaft of the motor; the other end of the lead screw is rotatably connected to the main body of the gear grinding machine; and the collection frame is threadedly connected to the lead screw.

[0009] The present invention is further configured such that: a liquid delivery pipe is provided between the four-way valve and the external high-pressure gas supply equipment, and two liquid delivery tanks are provided on the liquid delivery pipe; and a liquid delivery device is provided on the main body of the gear grinding machine to supply coolant and cooling oil to the two liquid delivery tanks respectively.

[0010] The present invention is further configured such that: the infusion set includes two drive boxes, each drive box having a delivery pipe and an eccentric wheel rotatably connected thereto; a second motor is fixedly connected to the drive box; the output shaft of the second motor is fixedly connected to the eccentric wheel; a suction pipe is fixedly connected to each of the two storage tanks; and the two ends of the two delivery pipes on both sides are fixedly connected to the two infusion tanks and the two suction pipes, respectively.

[0011] The present invention is further provided with a valve between the infusion tank and the infusion pipe.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention provides both coolant and cooling oil through two sets of coolant supply mechanisms, which users can switch between using a four-way valve. It also includes two collection boxes to collect and reuse the coolant and cooling oil respectively, preventing them from mixing. Furthermore, it features a small-volume coolant or cooling oil supply mechanism that, in conjunction with high-pressure gas, achieves a spray cooling effect, further enhancing the selectivity of cooling methods and allowing users to choose the appropriate cooling method based on the gear processing requirements.

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] A cooling device for gear grinding in a transmission, such as Figures 1-4 As shown, the device includes a gear grinding machine body 1, on which a flexible hose nozzle 2 is installed. A collection frame 3 is fixedly connected to the gear grinding machine body 1 and communicates with the processing chamber of the gear grinding machine body 1. A collection frame 4 is slidably connected to the collection frame 3. The gear grinding machine body 1 is equipped with a drive mechanism for moving the collection frame 4. The gear grinding machine body 1 is equipped with two coolant supply mechanisms, each including a storage tank 5 fixedly connected to the gear grinding machine body 1. The storage tank 5 is equipped with a flexible hose nozzle 2 and a flexible hose nozzle 3. The filter box 6 is connected to the main body of the gear grinding machine. The filter box contains several filter screens. The two filter boxes 6 are connected to the first collection frame 3 and the second collection frame 4 respectively. A four-way valve 7 is installed on the main body 1 of the gear grinding machine. The outlet of the four-way valve 7 is fixedly connected to the hose nozzle 2. The three inlets of the four-way valve 7 are connected to the two liquid storage tanks 5 and the external high-pressure gas supply equipment respectively. A delivery pump 16 is installed on the connecting pipe between the four-way valve 7 and the two liquid storage tanks 5. The pump's water inlet and water outlet are connected to the liquid storage tank and the four-way valve respectively.

[0024] Furthermore, the drive mechanism includes a motor 8 fixedly connected to the gear grinding machine body 1, and a lead screw 9 fixedly connected to one end of the output shaft of the motor 8. The other end of the lead screw 9 is rotatably connected to the gear grinding machine body 1, and the collection frame 4 is threadedly connected to the lead screw 9.

[0025] Furthermore, a liquid delivery pipe 10 is installed between the four-way valve 7 and the external high-pressure gas supply equipment. Two liquid delivery tanks 11 are opened on the liquid delivery pipe 10. The main body 1 of the gear grinding machine is equipped with a liquid delivery device that supplies coolant and cooling oil to the two liquid delivery tanks 11 respectively.

[0026] Furthermore, the infusion set includes two drive boxes 12, with a delivery pipe 13 passing through the drive box 12 and an eccentric wheel 14 rotatably connected thereto. A second motor (not shown in the figure) is fixedly connected to the drive box 12, and the output shaft of the second motor is fixedly connected to the eccentric wheel 14. A suction pipe 15 is fixedly connected to each of the two storage tanks 5. The two ends of the two delivery pipes 13 on both sides are fixedly connected to the two infusion tanks 11 and the two suction pipes 15, respectively.

[0027] Furthermore, a valve 17 is installed between the infusion tank 11 and the infusion pipe 13.

[0028] Working principle: The user fills the two storage tanks 5 with coolant and cooling oil respectively, and then selects air cooling, water cooling or oil cooling according to the gear processing situation. Then, the four-way valve 7 is used to adjust the connection of the hose nozzle 2 to the external high-pressure gas supply equipment, the coolant storage tank 5 or the cooling oil storage tank 5. When using coolant for cooling, the delivery pump 16 will send coolant to the hose nozzle 2, and the collection frame 3 will collect the coolant. After being filtered by the filter box 6, the coolant returns to the storage tank 5 for recycling. When it is necessary to switch to cooling oil, the four-way valve 7 is used to switch the connection mode, and then the motor 8 drives the lead screw 9 to rotate. The lead screw 9 will drive the collection frame 4 to move into the collection frame 3 until the collection frame 3 is completely covered by the collection frame 4. At this time, the collection frame 4 will replace the collection frame 3 to collect the cooling oil, preventing the coolant and cooling oil from mixing.

[0029] When air cooling is required, the four-way valve 7 switches the connection mode, allowing high-pressure cold air to be supplied to the hose nozzle 2 via an external high-pressure gas supply device. Alternatively, the eccentric wheel 14 can be rotated by the motor 2, and a small amount of coolant or cooling oil can be delivered into the delivery pipe 10 through the liquid delivery pipe 13 and the liquid extraction pipe 15. This coolant or cooling oil is then quickly delivered to the workpiece by the high-pressure airflow. During this process, the high-pressure airflow also disperses the coolant or cooling oil, achieving a spray-like cooling effect. With this configuration, the gear grinding machine has both coolant and cooling oil available for the user to choose from, and the two are not easily mixed, preventing the cooling effect of the coolant or cooling oil from decreasing due to mixing and emulsification. A small-volume supply mechanism for coolant or cooling oil is also provided, which, together with the high-pressure airflow, achieves a spray cooling effect for the coolant or cooling oil, further improving the selectivity of the cooling method and making it easier for the user to select the appropriate cooling method according to the gear processing requirements.

[0030] It is also worth mentioning that a circulating cooling structure for coolant or cooling oil can be added to the storage tank to improve the cooling system's endurance. The circulating cooling structure for coolant is a mature existing technology, so it will not be elaborated on here.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
