AI Technical Summary
In traditional progressive grinding devices, the coolant cannot evenly cover the bushing surface during the bushing grinding process, resulting in localized thermal deformation and affecting grinding accuracy and surface quality.
The system employs a combination of synchronous and recycling components, including a water tank, cooling pump, nozzle, drive rod, collection box, and heat exchanger, to achieve uniform spraying and recycling of coolant, ensuring effective cooling of the bushing surface.
This improves the cooling effect on the bushing surface, avoids thermal deformation, and enhances the precision and quality of the grinding process.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bushing surface processing technology, specifically relating to a progressive device for bushing grinding milling cutter. Background Technology
[0002] Bushing surface machining refers to the precision processing of the outer diameter, inner diameter, or end face of a bushing (a mechanical component used to support a rotating shaft) through mechanical cutting, grinding, or special machining processes to achieve specified dimensional accuracy, geometric tolerances, and surface roughness requirements. Common processes include turning, milling, grinding, and polishing, aiming to ensure the assembly accuracy, wear resistance, and operational stability of the bushing and mating parts. Heat treatment or coating processes may also be involved to enhance surface properties.
[0003] In the process of bushing machining, in order to ensure high-precision plane or contour grinding effect, progressive grinding device is usually required. However, there is a problem with traditional progressive devices: because the coolant cannot evenly cover the entire bushing surface during machining, the cooling effect in local areas is poor. This uneven cooling will cause local thermal deformation, which will ultimately affect the grinding accuracy and surface quality of the bushing. Utility Model Content
[0004] The purpose of this invention is to provide a progressive device for grinding mill cutters on bushings, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example
[0029] Reference Figure 1-6 This embodiment of the present invention provides a progressive device for grinding a bushing flat end mill, comprising:
[0030] The machining mechanism 100 includes a machining table 110, a milling cutter component 120 disposed on the top of the machining table 110, a progressive component 130 disposed on the top of the machining table 110, and a bushing 140 sleeved on the output end of the progressive component 130.
[0031] The cooling mechanism 200 includes a synchronization component 210 for improving the cooling effect on the surface of the bushing 140, and a recycling component 220 for recycling the coolant.
[0032] The coordination between the synchronization component 210 and the recovery component 220 improves the cooling effect on the surface of the bushing 140, avoids affecting the grinding effect of the bushing 140 surface, and solves the problem that the coolant cannot guarantee complete coverage of the bushing 140 surface during the grinding process of the traditional progressive device, thus affecting its cooling effect. This achieves the goal of improving the cooling effect on the surface of the bushing 140 and improving its grinding effect.
[0033] Specifically, the synchronization component 210 includes a water tank 211 fixedly installed on the top of the processing table 110, a movable plate 212 slidably installed on one side of the water tank 211, a cooling pump 213 fixedly installed on the movable plate 212, a nozzle 214 provided at the output end of the cooling pump 213, and a transmission rod 215 that is linked to the movable plate 212 and fixedly installed on the progressive component 130.
[0034] The other end of the transmission rod 215 is connected to the telescopic component of the progressive component 130.
[0035] Furthermore, a slide rail 216 is fixedly installed on one side of the water tank 211, and a slider 217 is slidably installed on the inner side of the slide rail 216. The input end of the cooling pump 213 is connected to a liquid inlet pipe 218.
[0036] The sliding rail 216 and the slider 217 work together to limit the movement of the moving plate 212, thereby improving the stability of the nozzle 214 during movement.
[0037] Preferably, the end of the transmission rod 215 is fixedly connected to the slider 217, and the surface of the slide rail 216 is provided with holes for use with the transmission rod 215.
[0038] The hole is used to limit the transmission rod 215 to prevent it from shifting, which would result in poor connection stability between the transmission rod 215 and the slider 217.
[0039] Furthermore, the end of the liquid inlet tube 218 extends to the bottom of the inner cavity of the water tank 211, and the top of the water tank 211 is provided with a strip groove for moving the liquid inlet tube 218.
[0040] Furthermore, the recovery component 220 includes a collection tank 221 fixedly installed at the bottom of the processing table 110 for coolant recovery, a heat exchanger 222 fixedly installed at the bottom of the processing table 110 for cooling the coolant, a circulation pump 223 fixedly installed at the top of the processing table 110 for circulating the coolant, and a return pipe 224 connected to the output end of the circulation pump 223.
[0041] The circulating pump 223 is used to pump out the coolant recovered inside the collection tank 221. The coolant enters the heat exchanger 222 through the connecting pipe 225. When the coolant passes through the heat exchanger 222, it is cooled down. Then it flows back to the water tank 211 through the return pipe 224, realizing the recycling of the coolant.
[0042] Specifically, a connecting pipe 225 connects the collection box 221 and the heat exchanger 222, and a filter screen 226 for filtering chips is installed inside the collection box 221.
[0043] The filter screen 226 is used to filter the chips to prevent them from clogging the connecting pipe 225 and obstructing the coolant circulation.
[0044] Furthermore, the filter screen 226 is located above the connecting pipe 225, and a liquid guide pipe is connected between the input end of the circulating pump 223 and the heat exchanger 222.
[0045] In use, the bushing 140 is fitted onto the output end of the progressive component 130. The surface of the bushing 140 is ground smooth by the milling cutter component 120. Under the action of the cooling pump 213, the coolant stored in the water tank 211 is pumped out through the liquid inlet pipe 218 and then sprayed onto the surface of the bushing 140 through the nozzle 214 to cool it. When the progressive component 130 progressively treats the surface of the bushing 140, the telescopic component on the progressive component 130 will drive the transmission rod 215 to move. The transmission rod 215 drives the slider 217 to move, so that it slides inside the slide rail 216. Then the slider 217 drives the moving plate 212, the cooling pump 213 and the nozzle 214 to move synchronously with the bushing 140, keeping the relative position of the nozzle 214 and the bushing 140 unchanged, thereby improving the cooling effect on the surface of the bushing 140.
[0046] After use, the coolant is collected inside the water tank 211. The filter screen 226 filters out the coolant debris. The coolant collected inside the collection tank 221 is pumped out by the circulation pump 223. When the coolant passes through the heat exchanger 222, the heat exchanger 222 cools it down. Finally, the coolant is returned to the inside of the water tank 211 through the return pipe 224, realizing the recycling of the coolant.
[0047] In summary, the coordination between the synchronization component 210 and the recovery component 220 improves the cooling effect on the surface of the bushing 140, avoids affecting the smoothing effect of the bushing 140 surface, and solves the problem that the coolant cannot guarantee complete coverage of the bushing 140 surface during the smoothing process of the traditional progressive device, thus affecting its cooling effect. This achieves the goal of improving the cooling effect on the surface of the bushing 140 and improving its smoothing effect.
