Description

Technical Field

[0001] This utility model relates to the technical field of precision device processing, specifically to a precision device grinding processing apparatus. Background Technology

[0002] Precision components refer to components with extremely high requirements for size, shape, and performance during design, manufacturing, and use. They possess high precision, durability, and reliability, and are widely used in aerospace, medical equipment, electronic products, optical instruments, and other fields.

[0003] Precision components can be designed in different shapes depending on the application scenario, including cylindrical, plate, and irregular shapes. Among them, plate-shaped precision components are widely used in electronic component substrates, housings, and mechanical parts. In the existing precision component grinding process, limiting components are usually used to fix the precision component before grinding. After grinding one side, the limiting components need to be loosened to remove the precision component, flip it over, and then fix it again for grinding the other side. This affects the production rate and increases the burden on employees. Therefore, we designed a precision component grinding processing device. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding and processing device for precision components. After grinding one side is completed, the device automatically grinds the other side, reducing the workload of personnel, speeding up the production rate, and ensuring that the precision components remain stable during grinding and flipping, preventing shaking and falling, thus solving the problems in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A precision device for grinding and processing includes an operation plate, a mounting frame is fixedly connected to the upper surface of the operation plate, a driving grinding component is fixedly installed on the mounting frame, a flipping hole is opened on the operation plate, a hydraulic base is fixedly installed in the flipping hole, a placement plate is fixedly connected to the output end of the hydraulic base, an electric slide rail is fixedly installed on the upper surface of the operation plate and in front of the flipping hole, and a movable base is fixedly connected to the upper surface of the slider in the electric slide rail;

[0006] The movable base has a through hole and a rotating rod is movably connected thereto. A gear is movably connected to the front of the movable base. The gear has a ratchet groove. A strip groove is formed on the outer side of the rotating rod. A pawl is movably connected to the strip groove and contacts the ratchet groove. A spring plate is fixedly connected to the inner wall of the strip groove. The other end of the spring plate is fixedly connected to the pawl. A rack is fixedly connected to the upper surface of the operating plate and to the front of the electric slide rail. A limit component is provided on the placement plate.

[0007] Through the above technical solution, this application places the precision component on the placement tray and limits it with a limiting component. Then, the driving grinding component is activated to perform the grinding process. After the precision component is ground on one side, the electric slide rail is activated to move the moving base. The limiting component and the internal precision component will move accordingly. At this time, the pawl on the rotating rod abuts against the ratchet groove in the gear. When the gear and rack mesh, they will drive the limiting component and the internal precision component to move, rotate, and flip over until the unground side of the precision component is facing up. Then, the electric slide rail resets and drives the moving base to reset. At this time, the pawl disengages from the ratchet groove, and the gear rotates without driving the rotating rod to rotate. The precision component is moved to the placement tray for grinding on the other side, thus completing the automatic flipping, reducing the burden on personnel, and speeding up the production rate. The hydraulic base will drive the placement tray to move so that the placement tray is close to the flipped precision component, providing better support. The driving grinding component consists of a cross slide, a lifting component, a driving component, and a grinding disc, which allows the grinding disc to move in all directions for grinding. This is an existing device and will not be described in detail here.

[0008] Preferably, the straight teeth on the rack are located on the left half of the rack, the gear is located above the rack, and the shape of the gear is adapted to the rack.

[0009] Through the above technical solution, the movable base of this application first moves horizontally, so that the precision device is separated from the placement plate and the drive grinding component. Then, after the gear and rack mesh, it flips over. At this time, the precision device is located in the flip hole and has enough space when rotating, so as not to affect the normal use of other components.

[0010] Preferably, the limiting component includes a first fixed frame, a sliding plate, a second fixed frame, and an electric telescopic rod. The first fixed frame is fixedly connected to the end of the rotating rod away from the gear. The upper surface of the operating plate and the rear side of the flip hole are slidably connected to the sliding plate. The front side of the sliding plate is provided with the second fixed frame. The rear side of the sliding plate is fixedly installed with the electric telescopic rod. The output end of the electric telescopic rod passes through the sliding plate and is movably connected to the second fixed frame through a plane bearing.

[0011] Through the above technical solution, this application starts the electric telescopic rod to drive the second fixed frame to move, thereby limiting the precision components in the first fixed frame and the second fixed frame to prevent them from shaking and falling. At this time, when the first fixed frame moves with the rotating rod, it will drive the second fixed frame and the precision components to move, while limiting the precision components from the outside, without affecting the grinding process of the driving grinding component.

[0012] Preferably, the limiting component further includes a slot and a rod. The first fixing frame has a slot at the end away from the rotating rod, and the second fixing frame has a rod fixedly connected at the end away from the sliding plate. The rod is slidably connected in the slot.

[0013] Through the above technical solution, the insertion rod of this application, when inserted into the slot, strengthens the limiting effect of the first fixed frame and the second fixed frame, and on the other hand, it can be more stable when the first fixed frame rotates and drives the second fixed frame to rotate, so that there will be no phenomenon of detachment or falling off.

[0014] Preferably, both the slot and the insert are cross-shaped, and both the first fixing frame and the second fixing frame are located above the placement tray.

[0015] Preferably, the length of the flip hole is adapted to the length of the electric slide rail, and the width of the flip hole is greater than the diameter of the placement tray.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] 1. The precision component grinding device, after fixing the precision component, grinds it by driving the grinding component. After grinding one side, the precision component moves and flips in the flipping hole, so that the other un-grinded side is facing up, and then moves and resets to the placement plate for grinding again. The entire grinding can be completed without manual flipping. At the same time, the flipping process will not affect the normal operation of other components, thus solving the problems mentioned in the background technology.

[0018] 2. The grinding and processing device for this precision component, through the design of the limiting component, ensures the stability of the precision component during the grinding process, prevents shaking from affecting the grinding accuracy, and limits the precision component when it moves and flips to prevent it from falling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a precision device for grinding and processing, including an operation plate 1, a mounting frame 2 fixedly connected to the upper surface of the operation plate 1, a driving grinding component 3 fixedly installed on the mounting frame 2, a flipping hole 4 opened on the operation plate 1, a hydraulic base 5 fixedly installed in the flipping hole 4, a placement plate 6 fixedly connected to the output end of the hydraulic base 5, an electric slide rail 7 fixedly installed on the upper surface of the operation plate 1 and in front of the flipping hole 4, and a movable base 8 fixedly connected to the upper surface of the slider in the electric slide rail 7;

A limit assembly 16 is provided on the placement plate 6.

[0027] Through the above technical solution, this application places the precision component on the placement tray 6 and limits it with the limiting component 16. Then, the grinding component 3 is activated to perform the grinding process. After the single side of the precision component is ground, the electric slide rail 7 is activated to move the moving base 8. The limiting component 16 and the internal precision component will move accordingly. At this time, the pawl 13 on the rotating rod 9 abuts against the ratchet groove 11 in the gear 10. When the gear 10 meshes with the rack 15, it will drive the limiting component 16 and the internal precision component to move, rotate, and flip over until the unground surface of the precision component is facing upwards. Then, the electric... When the slide rail 7 resets, it drives the movable base 8 to reset. At this time, the pawl 13 disengages from the ratchet groove 11, and the gear 10 rotates without driving the rotating rod 9 to rotate. The precision part is moved to the placement plate 6 for grinding on the other side, thus completing the automatic flipping, reducing the burden on personnel, and speeding up the production rate. The hydraulic base 5 will drive the placement plate 5 to move so that the placement plate 5 is in close contact with the flipped precision part, providing better support. The driving grinding component 3 consists of a cross slide, a lifting component, a driving component, and a grinding disc, which allows the grinding disc to move in all directions for grinding. This is an existing device and will not be described in detail here.

[0028] The straight teeth on the rack 15 are located on the left half of the rack 15, and the gear 10 is located above the rack 15, and the shape of the gear 10 is adapted to the rack 15.

[0029] Through the above technical solution, the movable base 8 of this application first moves horizontally, so that the precision device is separated from the placement plate 6 and the drive grinding component 3. Then, after the gear 10 and the rack 15 mesh, it flips over. At this time, the precision device is located in the flip hole 4, and there is enough space when it rotates, so as not to affect the normal use of other components.

[0030] The limiting assembly 16 includes a first fixed frame 161, a slide plate 163, a second fixed frame 164, and an electric telescopic rod 166. The first fixed frame 161 is fixedly connected to the end of the rotating rod 9 away from the gear 10. The slide plate 163 is slidably connected to the upper surface of the operating plate 1 and to the rear side of the flip hole 4. The second fixed frame 164 is provided on the front side of the slide plate 163. The electric telescopic rod 166 is fixedly installed on the rear side of the slide plate 163. The output end of the electric telescopic rod 166 passes through the slide plate 163 and is movably connected to the second fixed frame 164 through a plane bearing.

[0031] Through the above technical solution, the electric telescopic rod 166 is activated to drive the second fixed frame 164 to move, thereby limiting the precision components in the first fixed frame 161 and the second fixed frame 164 to prevent them from shaking and falling. At this time, when the first fixed frame 161 moves with the rotating rod 9, it will drive the second fixed frame 164 and the precision components to move, while limiting the precision components from the outside, without affecting the grinding process of the driving grinding assembly 3.

[0032] The limiting component 16 also includes a slot 162 and a rod 165. The first fixing frame 161 has a slot 162 at the end away from the rotating rod 9, and the second fixing frame 164 has a rod 165 fixedly connected at the end away from the slide plate 163. The rod 165 is slidably connected in the slot 162.

[0033] Through the above technical solution, the insertion rod 165 of this application is inserted into the slot 162, which on the one hand strengthens the limiting effect of the first fixed frame 161 and the second fixed frame 164, and on the other hand, it can be more stable when the first fixed frame 161 rotates and drives the second fixed frame 164 to rotate, so that there will be no phenomenon of detachment and falling off.

[0034] Both slot 162 and insert 165 are cross-shaped, and the first fixing frame 161 and the second fixing frame 164 are located above the placement plate 6.

[0035] The length of the flip hole 4 is matched with the length of the electric slide rail 7, and the width of the flip hole 4 is greater than the diameter of the placement plate 6.

[0036] When the precision component polishing device is working, the precision component is placed on the placement tray 6, and then the electric telescopic rod 166 is activated to move the second fixed frame 164, thereby clamping and limiting the precision component in the first fixed frame 161 and the second fixed frame 164. The polishing component 3 is then activated to perform the polishing process. After the precision component is polished on one side, the electric slide rail 7 is activated to move the moving base 8. The precision component will follow the moving base 8 to the straight teeth on the rack 15. At this time, the pawl 13 on the rotating rod 9 presses against the ratchet groove 11 in the gear 10. When the gear 10 meshes with the rack 15, the gear 10 rotates and drives the rotating rod 9 and the precision component to move and rotate until the unpolished side of the precision component faces upward. Then the electric slide rail 7 resets and drives the moving base 8 to reset. At this time, the pawl 13 disengages from the ratchet groove 11, and the gear 10 rotates without driving the rotating rod 9 to rotate. The precision component is then moved to the placement tray 6 for polishing on the other side, thus completing the automatic flipping.
