Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a device for removing coolant from the surface of parts using compressed air. Background Technology

[0002] In the gear manufacturing industry, machining processes such as gear hobbing and gear shaping are widely used in the forming of various transmission gears. To reduce tool wear, control machining temperature, and improve surface quality, a large amount of water-based or oil-based cutting fluid is usually continuously sprayed as a coolant during the machining process. However, after machining, a large amount of residual coolant often adheres to the workpiece surface and inside the gear grooves. If the residual coolant is not effectively removed, it will adversely affect subsequent processes and also result in coolant waste.

[0003] In existing technologies, the workpiece is usually placed in a container to drain naturally.

[0004] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: natural draining has low efficiency and long cycle, occupying a large amount of production time. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of the present invention is to provide a device for removing coolant from the surface of parts using compressed air, which can achieve coolant recycling while ensuring workpiece cleanliness.

[0006] To achieve the above objectives, the present invention provides an apparatus for removing coolant from the surface of parts using compressed air, comprising: Box; The lid is hinged to the top of the box body; The material rack, located inside the box, is used to support the workpiece; Gas source; The first reversing valve is located at the top of the housing. The air inlet of the first reversing valve is connected to the air source through a pipeline. The operating end of the first reversing valve is configured to be triggered after the housing cover is closed, thereby controlling the opening and closing of the air passage inside the first reversing valve. Multiple nozzles are disposed on the inner wall of the housing and connected to the air outlet port of the first reversing valve, for spraying compressed air onto the workpiece to remove the coolant from the surface when the air passage inside the first reversing valve is open.

[0007] According to one embodiment of the present invention, a filter is further included, which is disposed on the side wall of the housing for filtering the exhaust gas carrying coolant droplets after the workpiece has been purged in the housing, separating the droplets and purifying the exhaust gas.

[0008] According to one embodiment of the present invention, the device further includes a cylinder bracket and a cylinder, the cylinder bracket being fixed to the inner wall of the housing, the cylinder body being mounted on the cylinder bracket, and the piston rod of the cylinder being disposed toward the housing cover for pushing the housing cover to open upward about the hinge axis when extended.

[0009] According to one embodiment of the present invention, a second reversing valve is further included. The inlet port of the second reversing valve is connected to the air source through a pipeline, and the outlet port of the second reversing valve is connected to the rodless chamber and the rod chamber of the cylinder, for controlling the extension and retraction of the piston rod of the cylinder.

[0010] According to one embodiment of the present invention, the second directional valve is operated manually.

[0011] According to one embodiment of the present invention, the side wall of the housing is provided with an opening, a nozzle mounting hole and a filter mounting hole; the nozzle mounting hole is used to install the nozzle, and the filter mounting hole is used to install the filter; the filter mounting hole is located on the circumferential periphery of the opening, and the nozzle mounting hole is located above the opening.

[0012] According to one embodiment of the present invention, the material rack includes two longitudinal beams, two side beams, an upper beam, and a lower beam; the number of longitudinal beams is two, which are arranged in the front-to-back direction inside the box; the upper beam is arranged above the longitudinal beams in the left-to-right direction; the lower beam is connected between the two longitudinal beams in the left-to-right direction; the lower end of each side beam is connected to the corresponding longitudinal beam, and the upper end is inclined outward and fixedly connected to the side wall of the box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention utilizes compressed air to remove coolant from the surface of parts. By setting a first reversing valve, a mechanical safety interlock mechanism is formed to ensure that compressed air is only sprayed out when the housing is sealed, effectively preventing operators from being accidentally injured by high-speed airflow when the cover is open, thus improving the safety of use.

[0015] 2. This invention arranges multiple nozzles on the inner wall of the chamber, which can blow the surface of the workpiece in all directions. Compared with natural drainage, it can quickly remove residual coolant or oil stains and significantly improve cleaning efficiency.

The rack 3 is fixedly connected inside the housing 1; optionally, it is fixed to the inner wall of the housing 1 by welding or bolts. A gap is left between the rack 3 and the bottom of the housing 1 to allow space for coolant. The specific shape of the rack 3 is determined according to actual needs and is not limited thereto; for example, the rack 3 can be formed by welding multiple metal rods. The air source 16 can be compressed air.

[0027] The first reversing valve 4 is located at the top of the housing 1. The first reversing valve 4 can be fixed to the top of the housing 1 with fasteners. The specific type of the first reversing valve 4 is selected according to actual needs and is not limited thereto; for example, the first reversing valve 4 is a two-position two-way valve. The air inlet port of the first reversing valve 4 is connected to the air source 16 via a pipeline. The operating end of the first reversing valve 4 is configured to be triggered after the housing cover 2 is closed, controlling the opening and closing of the internal air passage of the first reversing valve 4.

[0028] Multiple nozzles 9 are disposed on the inner wall of the housing 1 and connected to the air outlet of the first reversing valve 4. They are used to spray compressed air onto the workpiece 7 to remove surface coolant when the internal air passage of the first reversing valve 4 is open. The specific number and installation position of the nozzles 9 are selected according to actual needs and are not limited thereto. For example, there are a total of 8 nozzles 9, symmetrically arranged on the inner walls of the left and right sides of the housing 1. The first reversing valve 4 has two working positions. In the first working position, the nozzles 9 are connected to the air source 16; in the second working position, the nozzles 9 are disconnected from the air source 16. The two working positions are switched by opening and closing the housing cover 2.

[0029] The device for removing coolant from the surface of parts using compressed air in this embodiment of the invention arranges multiple nozzles on the inner wall of the chamber, which can blow the surface of the workpiece in all directions.
