Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for gear grinding machines, specifically a cutting fluid treatment device for gear grinding machines. It is used to purify the cutting fluid containing impurities generated during the gear grinding process, enabling the recycling of the cutting fluid. This belongs to the branch of environmental protection and energy-saving equipment technology supporting mechanical processing. Background Technology

[0002] In gear grinding production, cutting fluid plays a crucial role in cooling, lubrication, and chip removal. However, as the process continues, the cutting fluid will mix with metal shavings (such as iron filings produced during gear machining), grinding wheel powder, oil, and other impurities.

[0003] Existing technologies have the following problems: Traditional processing devices mostly use a single filtration structure, which makes it difficult to simultaneously separate ferromagnetic debris, particles of different sizes, and oil stains, resulting in poor cutting fluid purification effect, affecting the precision of gear grinding (such as impurities scratching the workpiece surface), and shortening the service life of the cutting fluid; processes such as fluid inlet, slag discharge, and fluid return rely on manual intervention, such as manually cleaning filter residue and adjusting flow rate, which is not only inefficient, but also prone to impurity accumulation and system blockage due to untimely operation, increasing the risk of equipment failure; due to poor purification effect, the cutting fluid needs to be replaced frequently, increasing production costs, and waste cutting fluid is prone to causing environmental pollution, which is not in line with the concept of green manufacturing.

[0004] Therefore, it is necessary to design a cutting fluid treatment device for gear grinding machines to solve the problems mentioned above. Utility Model Content

[0005] This utility model discloses a cutting fluid treatment device for gear grinding machines, which aims to solve the problems of incomplete cleaning of impurities, low recycling rate and reliance on manual operation in existing cutting fluids for gear grinding machines, and to realize automated and efficient treatment and recycling of cutting fluids.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting fluid treatment device for a gear grinding machine, through the coordinated operation of the gear grinding machine body, treatment tank, fluid inlet assembly, spiral slag discharger, fluid return assembly, and control device, constructs a complete treatment process of cutting fluid "discharge → purification → circulation".

[0008] Furthermore, the device includes a gear grinding machine body, a processing chamber, a liquid inlet assembly, a spiral slag remover, a liquid return assembly, and a control device. The processing chamber, serving as the basic carrier for cutting fluid treatment, is internally divided into different chambers for cutting fluid pretreatment and filtration, providing stable installation space for each processing component. The liquid inlet assembly is responsible for transporting the cutting fluid discharged from the gear grinding machine body into the processing chamber, initiating the cutting fluid treatment process. The spiral slag remover, located at the slag discharge port on the right side of the processing chamber, pushes and removes large particles of impurities and separated iron filings from the cutting fluid; its lower slag outlet discharges the pushed impurities. The liquid return assembly transports the purified cutting fluid from the processing chamber back to the cutting fluid supply system of the gear grinding machine body, achieving cutting fluid recycling. The control device is electrically connected to the liquid inlet assembly, spiral slag remover, and liquid return assembly, regulating the coordinated operation of each component to complete the automated cutting fluid treatment process.

[0009] Furthermore, the fluid inlet assembly consists of an inlet pump and an inlet pipe. The input end of the inlet pump is connected to the cutting fluid outlet of the gear grinding machine body via the inlet pipe, and the output end also extends into the interior of the processing chamber via the inlet pipe. A permanent magnet assembly is connected to the end of one section of the inlet pipe located inside the processing chamber. The permanent magnet assembly is arranged in a ring along the inner wall of the inlet pipe, effectively adsorbing ferromagnetic metal debris in the cutting fluid and reducing subsequent filtration pressure.

[0010] Furthermore, a filter assembly is located inside the processing chamber, below the permanent magnet assembly. This filter assembly is a fine filter layer, employing a pleated filter membrane, capable of finely filtering the cutting fluid and separating fine particulate impurities. A ramp with through holes is also provided between the right side of the filter assembly and the inner shell of the processing chamber. Above the filter assembly is a scraper assembly, which includes a cylinder fixedly mounted on the left side of the inner shell of the processing chamber. A scraper is connected to the cylinder's power output shaft. The scraper removes debris from the upper surface of the filter assembly and pushes it through the through holes on the right side into the spiral slag discharger, preventing impurities from clogging the filter assembly and ensuring filtration efficiency.

[0011] Furthermore, the return fluid assembly includes a return fluid pump and a return fluid pipe. The input end of the return fluid pump is connected to the bottom cavity inside the processing tank through a pipe, and the output port is connected to the cutting fluid supply system of the gear grinding machine through the return fluid pipe, ensuring that the purified cutting fluid can flow back to the gear grinding machine smoothly, realize recycling, and reduce production costs.

[0012] Furthermore, the control device includes a controller and a human-machine interface connected to the controller. The controller is electrically connected to the control terminals of the liquid inlet component, the spiral slag discharger, and the liquid return component. The human-machine interface is embedded in the front housing of the gear grinding machine. The operator can send control signals to the controller through the human-machine interface. After receiving the corresponding control signals, the controller controls other components to work together to achieve automated control of the entire processing process. This makes the operation convenient and reduces the intensity of manual labor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, the cutting fluid treatment device for a gear grinding machine can achieve the following effects:
