[0047] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] like Figures 1-7 As shown, this invention discloses a centerless grinder in one embodiment. The grinder base 110, as the basic support structure of the entire machine, must possess sufficient strength and stability to bear the weight of each component and the forces generated during grinding. A robust and stable grinder base 110 ensures the position of components such as the grinding wheel 120, slide 130, and support plate 150 during operation, reducing machining errors caused by base deformation or wobbling. The base is generally rectangular or cubic in shape, with a large bottom surface area to increase stability. Various mounting holes and guide rail mounting surfaces are machined on the base for mounting the drive motor of the grinding wheel 120, the guide rail of the slide 130, and the adjustment mechanism of the support plate 150. The grinding wheel 120 is rotatably mounted on the grinder base 110 and grinds the outer cylindrical surface of the workpiece. Through its own rotation, the abrasive grains on its surface contact the outer cylindrical surface of the workpiece, achieving material removal and thus achieving the grinding purpose.

[0049] The sliding seat 130 is slidably mounted on the grinding machine base 110, and its main function is to adjust the distance between the guide wheel 140 and the grinding wheel 120. By sliding on the guide rail of the grinding machine base 110, the sliding seat 130 can control the position of the guide wheel 140 and change the size of the grinding space 121. The guide wheel 140 is rotatably mounted on the sliding seat 130, and together with the grinding wheel 120, it forms the grinding space 121. Through its relative rotation with the grinding wheel 120, it drives the workpiece to rotate within the grinding space 121, thereby achieving the grinding of the outer cylindrical surface of the workpiece. The support plate 150 is slidably mounted on the grinding machine base 110, located between the grinding wheel 120 and the guide wheel 140, and can support the workpiece and adjust its position in the grinding space 121 to accommodate the processing of workpieces of different sizes. The support roller 160 is rotatably mounted on the support plate 150 and abuts against the outer cylindrical surface of the workpiece, serving to support the workpiece. During the grinding process, the support roller 160 rotates along with the workpiece, reducing the friction between the workpiece and the support plate 150, ensuring that the workpiece can rotate smoothly, and preventing the workpiece from deforming due to uneven force.

[0050] In practical use, firstly, by controlling the motor of the sliding seat 130, the sliding seat 130 slides on the guide rail of the grinding machine base 110, adjusting the distance between the guide wheel 140 and the grinding wheel 120 to form a suitable grinding space 121. Then, by controlling the motor of the support plate 150, the support plate 150 slides on the guide rail of the grinding machine base 110, adjusting the support plate 150 to a suitable position. The workpiece is placed on the support roller 160 of the support plate 150, ensuring that the outer surface of the workpiece is in close contact with the support roller 160, while simultaneously being located within the grinding space 121 between the grinding wheel 120 and the guide wheel 140. The drive motors of the grinding wheel 120 and the guide wheel 140 are started, causing the two grinding wheels to begin rotating. The rotation of the grinding wheel 120 and the guide wheel 140 drives the workpiece to rotate within the grinding space 121, while the support roller 160 rotates along with the workpiece. Once the outer surface of the workpiece has reached the predetermined grinding depth, the drive motors of the grinding wheel 120 and guide wheel 140 are stopped, causing the grinding wheel to stop rotating and completing the grinding of one workpiece.

[0051] The grinding machine achieves grinding of the outer cylindrical surface of the workpiece through the stable support of the grinding machine base 110, the cooperation of the grinding wheel 120 and guide wheel 140, and the support of the workpiece by the support plate 150 and support roller 160, meeting the requirements of modern machining for the outer surface processing of shaft and cylindrical parts. The adjustable design of the sliding seat 130 and support plate 150 allows the equipment to adapt to the processing of workpieces of different sizes, improving the equipment's versatility and processing adaptability, and reducing the cost of purchasing multiple pieces of equipment for processing different sized workpieces. The rational design and coordinated operation of each component ensure the continuity of the grinding process and improve processing efficiency. Simultaneously, the rotating design of the support roller 160 reduces friction between the workpiece and the support plate 150, extending the service life of the equipment and reducing maintenance costs.

[0052] In some examples, the feed frame 210 is positioned on one side of the grinding machine base 110, serving as the basic support structure for the feed mechanism. It provides a stable platform for the sliding of the feed rack 220 and the operation of the pick-up claw 230, while simultaneously determining the relative positional relationship between the feed mechanism and the grinding machine body, ensuring effective integration of the feed process with the grinding operation. The feed frame 210 ensures the stability of the feed process, enabling the feed mechanism to deliver the workpiece into the grinding space 121 and preventing workpiece position deviation due to unstable feed. The feed rack 220 is slidably mounted on the feed frame 210, its main function being to move the pick-up claw 230 closer to or further away from the grinding machine base 110, thereby enabling the workpiece to move between the feed position and the grinding space 121. The sliding design of the feed rack 220 allows the pick-up claw 230 to place the workpiece at a designated position in the grinding space 121, and then remove the workpiece after grinding. The sliding of the feed rack 220 improves feed efficiency and reduces errors and time waste that may occur with manual feed. The pick-up claw 230 is rotatably mounted on the feed frame 220, and it clamps and releases the workpiece through its own opening and closing action. The pick-up claw 230 can clamp and place the workpiece at different angles to adapt to the workpiece in the feeding position.

[0053] In actual use, the workpiece to be processed is placed in the feeding position, which is usually located near the feeding frame 210. Based on the size, shape, and weight of the workpiece, the clamping force and rotation angle of the pick-up claw 230, as well as the initial position of the feeding frame 220, are adjusted. The drive motor of the feeding frame 220 is started, moving the feeding frame 220 to the picking position, at which point the pick-up claw 230 is positioned above the workpiece. The cylinder or electric push rod of the pick-up claw 230 is controlled to open, then descend to a suitable position and close, clamping the workpiece. The shaft motor or cylinder of the pick-up claw 230 is controlled to operate. Then, the cylinder or electric push rod of the pick-up claw 230 is controlled to open, placing the workpiece on the support roller 160 of the pallet 150 within the grinding space 121.

[0054] In some examples, a flow space 151 is provided on the tray 150 and communicates with the inlet 152 to provide a transmission channel for the coolant. The inlet 152 serves as the coolant inlet and connects to an external coolant supply device, such as a cooling water tank 510 and a water pump. The coolant flows into the flow space 151 through the inlet 152 and then flows and distributes within the flow space 151, providing a stable coolant source for the nozzles 153. The stable coolant transmission channel ensures that the nozzles 153 can continuously and uniformly spray coolant, effectively reducing the temperature of the grinding wheel during the grinding process, reducing problems such as grinding wheel wear and workpiece surface burns caused by high temperatures, and improving the service life of the grinding wheel and the machining quality of the workpiece. Multiple nozzles 153 are obliquely arranged on the tray 150 and communicate with the flow space 151, facing the grinding wheel 120 and the guide wheel 140 respectively. The tilted nozzle 153 allows the coolant to be sprayed onto the grinding wheel at a certain angle, ensuring that the coolant can cover the working area of ​​the grinding wheel and fully exert its cooling and lubrication effects.

[0055] In actual use, the external coolant supply device is activated, such as turning on the water pump of the cooling water tank 510, allowing coolant to flow through the pipe from the inlet 152 into the flow space 151 of the support plate 150. Before the coolant flows in, check that the connection between the inlet 152 and the pipe is tight to ensure there are no leaks. The coolant flows within the flow space 151 and is evenly distributed to each nozzle 153. Due to the inclined setting of the nozzles 153, the coolant is sprayed from the nozzles 153 at a certain angle towards the grinding wheel 120 and the guide wheel 140. During the grinding process, the nozzles 153 continuously spray coolant, forming a cooling film on the surface of the grinding wheel, absorbing the heat generated during grinding and reducing the temperature of the grinding wheel. At the same time, the flushing action of the coolant washes away the debris generated during grinding, preventing debris from accumulating in the grinding area and affecting the grinding quality. The coolant sprayed onto the grinding wheel and the carried debris fall together and are collected through the coolant recovery tank provided on the grinding machine base 110. The recovered coolant can be recycled after filtration and cooling treatment to save resources and reduce production costs.

[0056] In some examples, a protective plate 310 is mounted on the sliding seat 130, providing a protective space 320 within which the guide wheel 140 is located. This design creates a relatively enclosed space around the guide wheel 140, using the protective plate 310 to prevent metal shavings and water droplets generated during grinding from splashing outwards. The protective plate 310 is integrated with the sliding seat 130 and moves as the sliding seat 130 slides, always maintaining protection for the guide wheel 140.

[0057] In actual use, the protective plate 310 is installed on the sliding seat 130, and the protective space 320 surrounds the guide wheel 140. Check whether the connection between the protective plate 310 and the sliding seat 130 is secure, and whether there are any foreign objects in the protective space 320. Also, ensure that the ventilation holes or heat dissipation grooves on the protective plate 310 are not blocked. During grinding, the guide wheel 140 rotates at high speed within the protective space 320. When metal chips and water droplets splash due to the rotation of the grinding wheel, the protective plate 310 acts as a barrier. After impacting the protective plate 310, the metal chips and water droplets slide down the inner wall of the protective plate 310. The protective plate 310 moves with the sliding seat 130, always maintaining protection for the guide wheel 140. Regardless of the position of the guide wheel 140 due to processing workpieces of different sizes, it can effectively prevent metal chips and water droplets from splashing.

[0058] The protective plate 310 provides reliable safety protection for operators, significantly reducing the risk of injury from splashing metal filings and water droplets, creating a safer working environment that meets the requirements of safe production. By preventing metal filings and water droplets from corroding other parts of the equipment, the protective plate 310 effectively protects critical components, reduces the frequency of equipment failures, extends equipment lifespan, lowers maintenance costs, improves equipment reliability and stability, and ensures continuous production. The protective plate 310 reduces the scattering of metal filings and water droplets in the work area, making the work site cleaner, facilitating daily cleaning and maintenance, improving the overall environmental quality of the production workshop, and contributing to increased production efficiency and a better corporate image.

[0059] In some examples, the grinding element 410 is slidably mounted on the sliding seat 130. This arrangement allows the grinding element 410 to move closer to or further away from the guide wheel 140 as the sliding seat 130 moves. When grinding of the guide wheel 140 is required, the movement of the sliding seat 130 is controlled to bring the grinding element 410 into contact with the surface of the guide wheel 140. After grinding is completed, the sliding seat 130 is controlled to release the grinding element 410 from contact, preventing it from interfering with the normal grinding process. After the grinding element 410 comes into contact with the surface of the guide wheel 140, the relative movement between the two allows the grinding element 410 to grind and finish the worn areas on the surface of the guide wheel 140. The material hardness of the grinding element 410 is usually higher than that of the abrasive of the guide wheel 140, which can effectively remove the uneven parts on the surface of the guide wheel 140 caused by wear, restore its ideal grinding surface shape and roughness, and ensure that the guide wheel 140 can provide grinding force during subsequent workpiece grinding.

[0060] In practical use, after the equipment has been running for a certain period of time or a certain number of workpieces have been ground, it serves as a further technical solution for enterprises to achieve efficient and stable production goals.

[0061] In some examples, a water reservoir 111 and a drain outlet 112 connected to it are provided on the grinding machine base 110 to collect the coolant sprayed during grinding and the debris carried along with it. The water reservoir 111 is the initial collection area for coolant. The drain outlet 112 is a channel connecting the water reservoir 111 to the water tank 510, allowing the collected coolant to flow smoothly into the water tank 510 for further processing. This efficient coolant collection design prevents coolant from scattering throughout the work area, maintaining a clean working environment. At the same time, it provides a basis for coolant recycling, enabling centralized recovery and reducing waste. The water tank 510, located inside the grinding machine base 110, serves to store coolant and provides space and an interface for coolant circulation. The circulation inlet 511 on the water tank 510 is connected to the drain outlet 112 to receive the coolant flowing in from the water storage tank 111; the circulation outlet 512 is connected to the inlet 152 of the tray 150 via the circulation pipe 520 to return the treated coolant to the nozzle 153 for spraying. One end of the circulation pipe 520 is connected to the circulation outlet 512 of the water tank 510, and the other end is connected to the inlet 152 of the tray 150, forming a channel for the coolant to be transported from the water tank 510 to the nozzle 153.

[0062] During the grinding process, nozzle 153 sprays coolant onto the grinding wheel 120 and guide wheel 140. After cooling and flushing away debris, the coolant carries the debris into the water storage tank 111 of the grinding machine base 110. Due to the special design of the water storage tank 111 and the position of the drain outlet 112, the coolant, under gravity, flows through the drain outlet 112 and along the connecting pipe into the sedimentation zone of the water tank 510. After flowing into the sedimentation zone of the water tank 510, the debris carried by the coolant gradually settles to the bottom of the sedimentation zone. After a period of sedimentation, the relatively clean coolant is located at the top of the sedimentation zone and flows into the circulation zone for storage. The baffle inside the water tank 510 separates the sedimentation zone from the circulation zone, preventing the settled debris from mixing back into the coolant in the circulation zone.

[0063] In some examples, the filter cover 610 is mounted on the grinding machine base 110 and covers the drain outlet 112. Its main function is to intercept larger particulate impurities, such as iron filings and grinding shavings, carried in the coolant before it flows into the drain outlet 112. The filter cover 610, through its specific filter screen 620 structure, allows only coolant and smaller particulate impurities to pass through, thus achieving preliminary filtration. This reduces the possibility of larger particulate impurities entering the water tank 510 and circulation pipes 520, preventing these impurities from causing wear and blockage to components such as the circulation pump 530 and nozzles 153, thereby extending the service life of the circulation system components and reducing equipment maintenance costs. The filter cover 610 can centrally intercept impurities, and periodically cleaning the filter cover 610 is more convenient and faster than cleaning the entire water tank 510 and circulation pipes 520, improving equipment maintenance efficiency and reducing equipment downtime due to maintenance.

[0064] In actual use, during the grinding process, the coolant sprayed onto the grinding wheel carries iron filings, grinding debris, and other impurities into the water storage tank 111. The coolant flows within the water storage tank 111 towards the drain outlet 112. When the coolant flows through the filter cover 610, larger particles of impurities are intercepted by the filter screen 620 and remain inside the filter cover 610, while the coolant flows through the mesh of the filter screen 620, from the bottom opening of the filter cover 610 into the drain outlet 112, and then into the water tank 510. As grinding continues, the amount of impurities intercepted inside the filter cover 610 gradually increases. When the impurities accumulate to a certain level, the filter cover 610 needs to be cleaned.

[0065] In some examples, the filter screen 620 is slidably disposed on the side wall of the filter cover 610. By sliding, the distance between the filter section 621 and the bottom of the water storage tank 111 is changed, thereby controlling the flow rate of coolant through the filter screen 620 into the drain outlet 112, and thus controlling the liquid level in the water storage tank 111. When the filter section 621 of the filter screen 620 is close to the bottom of the water storage tank 111, the contact area between the filter holes 623 and the liquid surface increases, the speed at which coolant flows into the drain outlet 112 through the filter holes 623 increases, and the liquid level in the water storage tank 111 drops; conversely, when the filter section 621 is far from the bottom of the water storage tank 111, the contact area between the filter holes 623 and the liquid surface decreases, the flow rate of coolant slows down, and the liquid level rises. The filter screen 620 has a filter section 621 and a blocking section 622. The filter holes 623 on the filter section 621 are used to filter impurities in the coolant, ensuring that only clean coolant enters the drain outlet 112. The blocking part 622 serves to assist in controlling the liquid level.

[0066] In some examples, the feeder 220 achieves multi-directional sliding through a complex mechanical structure, typically employing a Cartesian coordinate or articulated motion mechanism. A Cartesian coordinate mechanism consists of mutually perpendicular X, Y, and Z axes. The feeder 220 is mounted on sliders along these axes, and a servo motor drives gears to slide along a rack, thereby enabling the feeder 220 to achieve linear motion in three directions.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
