Description

Technical Field

[0001] This invention relates to the field of flat round head bolt grinding technology, specifically to an automatic grinding device for the burrs on the head of flat round head bolts. Background Technology

[0002] A flat head bolt is a fastener with a specific head shape. It consists of a cylindrical shank (with external threads) and a flat head. The cylindrical shank mates with a nut to achieve a fastening connection, which is a detachable connection. The head of the flat head bolt is flat and round, symmetrically bent into an arc shape along its diameter. This design increases the point of application of the tightening force and provides anti-loosening functionality. During the manufacturing process, burrs are prone to form on the head, affecting accuracy and aesthetics, requiring grinding.

[0003] Traditional grinding devices suffer from problems such as unstable clamping and inaccurate grinding head positioning when removing burrs, resulting in poor grinding effects and easy damage to the bolt surface. This invention utilizes pneumatic adsorption and gear drive to achieve stable workpiece clamping and precise positioning, effectively improving grinding accuracy, reducing surface damage, and increasing production efficiency. Summary of the Invention

[0009] Preferably, the cavity formed by the combination of the movable clamping seat and the fixed clamping seat is a flat round head bolt cavity, which is used to accommodate the flat round head bolt, ensuring stable clamping during rotation, preventing loosening, and improving assembly accuracy.

[0010] Preferably, the grinding assembly specifically includes a fixed base and a connecting column, both of which are mounted on a base. The top of the fixed base is fixedly connected to a limit block, and a push rod is movably connected in the inner hole of the limit block. A linkage block is fixedly connected to one end of the push rod. The bottom side of the fixed base is integrally connected to an auricle-shaped support body, and an electric telescopic rod is connected between the auricle-shaped support bodies. The telescopic end of the electric telescopic rod is fixedly connected to a tripod plate. The tripod plate has three legs, and the other two legs are respectively connected to the top of the linkage block and the connecting column. The top of the limiting block is movably connected to two telescopic cylinders. The telescopic ends of the two telescopic cylinders are respectively connected to an electric grinder and an atomizing nozzle. The electric grinder is connected to an external power source, and the atomizing nozzle is connected to an external cooling water pipe.

[0011] Preferably, the adsorption component specifically includes a curved plate, which is fixedly installed on the base. A connecting plate is fixedly installed on the top of the curved plate. Two support bearing seats are installed on the front of the connecting plate. The upper support bearing seat is connected to a drive seat through a rotating column A, and the lower support bearing seat is connected to a connecting rod seat through a rotating column B. The top of the connecting rod seat is connected to the rotating column A. A connecting hoop is fixedly installed on the back of the curved plate. The connecting hoop has an air pump inside.

[0013] Preferably, the drive base has a gear chamber inside, and a drive gear is installed in the gear chamber. The drive gear meshes with the tooth groove of the lower pressure cylinder. The shaft of the drive gear is connected to the output end of the third motor, which drives the lower pressure cylinder to move up and down to achieve precise positioning of the adsorption plate. The third motor is installed on the outer surface of the drive base.

[0014] This invention provides an automatic grinding device for the burrs on the head of flat round head bolts. It has the following beneficial effects: (1) This invention achieves stable clamping, precise positioning and rotation of workpieces through air pressure adsorption and gear drive, effectively improving grinding accuracy, reducing surface damage, improving production efficiency, and ensuring product consistency and quality; the unique three-legged irregular plate design and the matching of limit blocks provide a guarantee for easy and safe ejection operation, while the linkage between the electric grinder and the atomizing nozzle further improves work efficiency and reduces the labor intensity of workers.

[0015] (2) The present invention drives the gear to rotate through the motor, the gear drives the tooth block to move along the slide rail, and then pushes the moving rod to extend / retract in the fixed cylinder. Under the action of the clamping spring, the clamping head drives the movable clamping seat to tightly fit the flat round head bolt, so as to achieve firm clamping. Conversely, the flat round head bolt is loosened, so as to achieve flexible switching between clamping and releasing, ensuring convenient and efficient operation and improving the smoothness of the overall operation process.

[0016] (3) The present invention ensures uniform grinding by adjusting the process through the telescopic cylinder when the electric grinder is started; the atomizing nozzle sprays coolant simultaneously to prevent high temperature damage to the workpiece and improve grinding efficiency and quality; on the other hand, the electric telescopic rod adjusts the angle of the tripod plate so that the tripod plate can rotate flexibly around the support point connected to the top of the connecting column as the axis, thereby driving the push rod on the linkage block to move linearly under the limiting action of the limiting block, so as to accurately push out the flat round head bolt after grinding.

[0017] (4) The present invention uses a motor to drive the three-drive gear to rotate, which drives the lower pressure cylinder to move downward, thereby driving the adsorption plate to stick tightly to the surface of the workpiece. The compression spring provides reverse support force. At the same time, the air pump starts, and the airflow at the point where the adsorption plate and the flat round head bolt are tightly attached is quickly drawn away to form a negative pressure environment. The flat round head bolt is firmly adsorbed. The electronic pressure valve monitors and finely adjusts the air pressure in real time to form a stable adsorption force. At the same time, the buffer rubber column effectively reduces shock, protects the workpiece and equipment, and improves the overall operational stability and safety. Attached Figure Description

The adsorption component 5 adsorbs the bolt through negative pressure to ensure accurate positioning during feeding and reduce errors. Example

[0024] Please see Figures 1-6Furthermore, based on Embodiment 1, the following is further obtained: The specific structure of the bottom rotating component 2 includes a motor 21, which is mounted on an L-shaped mounting plate 13. The output end of the motor 21 is fixedly connected to a small gear 22 via a coupling. The small gear 22 meshes with a large gear 23 mounted on the bottom of the mounting platform 12. The axis of the large gear 23 coincides with the center hole of the mounting platform 12 and the rotating platform 25, and is fixed to the rotating platform 25 via a connecting shaft 24. The rotating platform 25 is located in the inner cavity of the mounting platform 12, and a rolling bearing is connected between the outer wall of the rotating platform 25 and the inner cavity wall of the mounting platform 12 to reduce friction and improve rotation accuracy. The top end of the connecting shaft 24 extends to the top of the mounting platform 12 and is connected to the clamping component 3. During rotation, the motor 21 drives the small gear 22 to rotate, which drives the large gear 23 and the rotating platform 25 to rotate synchronously, thereby realizing the overall rotation of the clamping component 3 and the bolt, ensuring that the burrs on the bolt head are removed evenly during the grinding process, and improving grinding efficiency and quality. Example

[0025] Please see Figures 1-6 Furthermore, based on embodiments 1 and 2, the following is obtained: The specific structure of the clamping assembly 3 includes a connecting seat 31, which is fixed to the top of the connecting shaft 24. A fixed clamping seat 315 is fixedly installed on the top of the connecting seat 31. A fixed rod 32 is fixedly installed in the inner hole of the connecting seat 31. A fixed arm 33 is fixedly connected to the other end of the fixed rod 32. A fixed cylinder 34 is fixedly connected to the other end of the fixed arm 33. A movable rod 35 is installed inside the cylinder. A clamping head 37 is fixedly connected to the end of the movable rod 35. A clamping spring 36 is sleeved on the outside of the movable rod 35. One end of the clamping spring 36 is fixedly connected to the fixed cylinder 34, and the other end is connected to the clamping head 37. A movable clamping seat 38 is fixedly installed on one side of the clamping head 37. A limit rod 39 is fixedly connected to the bottom of the clamping head 37. A toothed block 310 is fixedly connected to the other end of the limit rod 39. A slide rail 311 is slidably connected to the top of the toothed block 310. The slide rail 311 is fixedly installed at the bottom of the fixed cylinder 34. A gear 312 is meshed with the bottom of the toothed block 310. The gear 312 is movably installed on the mounting bracket 313. The mounting bracket 313 is fixed on the fixed rod 32. The shaft of the gear 312 is connected to the output end of the second motor 314. The second motor 314 is installed on the rotary table 25. The cavity formed by the cooperation of the movable clamping seat 38 and the fixed clamping seat 315 is a flat round head bolt cavity, which is used to accommodate the flat round head bolt, ensure that it is stably clamped during rotation, avoid loosening, and improve assembly accuracy. During the clamping process, the motor 314 first drives the gear 312 to rotate. The gear 312 drives the tooth block 310 to move along the slide rail 311, which in turn pushes the moving rod 35 to extend / retract within the fixed cylinder 34. Under the action of the clamping spring 36, the clamping head 37 drives the movable clamping seat 38 to tightly fit against the flat round head bolt, achieving a firm clamping. Conversely, the flat round head bolt is loosened, realizing a flexible switch between clamping and releasing, ensuring convenient and efficient operation, and improving the smoothness of the overall work process. Example

[0026] Please see Figures 1-6 Furthermore, based on embodiments 1, 2, and 3, the following is obtained: the specific structure of the grinding component 4 includes a fixed base 41 and a connecting column 46, both of which are mounted on the base 11; The top of the fixed base 41 is fixedly connected to a limiting block 42, and a push rod 48 is movably connected in the inner hole of the limiting block 42. A linkage block 47 is fixedly connected to one end of the push rod 48. The bottom side of the fixed base 41 is integrally connected to an auricle-shaped support 43, and an electric telescopic rod 44 is connected between the auricle-shaped support 43. The telescopic end of the electric telescopic rod 44 is fixedly connected to a tripod plate 45. The tripod plate 45 has three legs, and the other two legs are respectively connected to the top of the linkage block 47 and the connecting column 46. The top of the limiting block 42 is movably connected to two telescopic cylinders 49. The telescopic ends of the two telescopic cylinders 49 are respectively connected to an electric grinder 410 and an atomizing nozzle 411. The electric grinder 410 is connected to an external power source, and the atomizing nozzle 411 is connected to an external cooling water pipe. On the one hand, when the electric grinder 410 is started, the process is adjusted by the telescopic cylinder 49 to ensure uniform grinding; the atomizing nozzle 411 sprays coolant simultaneously to prevent high temperature damage to the workpiece and improve grinding efficiency and quality; on the other hand, the electric telescopic rod 44 adjusts the angle of the tripod plate 45 so that the tripod plate 45 can rotate flexibly around the support point connected to the top of the connecting column 46 as the axis, thereby driving the push rod 48 on the linkage block 47 to move linearly under the limiting action of the limiting block 42, so that the push rod 48 can accurately push out the flat round head bolt after grinding.

[0027] In this embodiment, the model of the electric grinder 410 varies depending on its brand, function, and design. Its specific structure and working principle will not be described in detail here. The atomizing nozzle 411 has a wide distribution of spray micro-holes, which evenly covers the coolant, effectively reducing the surface temperature of the workpiece, preventing thermal deformation, and further improving the grinding accuracy and surface finish. Example

[0028] Please see Figures 1-6Furthermore, based on Examples 1, 2, 3, and 4, the following is obtained: The specific structure of the adsorption component 5 includes a curved plate 51, which is fixedly installed on the base 11. A connecting plate 52 is fixedly installed on the top of the curved plate 51. Two support bearing seats 53 are installed on the front of the connecting plate 52. The upper support bearing seat 53 is connected to a drive seat 54 through a rotating column A55, and the lower support bearing seat 53 is connected to a connecting rod seat 57 through a rotating column B56. The top end of the connecting rod seat 57 is connected to the rotating column A55. A connecting hoop 58 is fixedly installed on the back of the curved plate 51. The connecting hoop 58 has an air pump 59 built in it. The air pump 59 is connected to a pressure cylinder 511 through an air pipe 510. The bottom of the pressure cylinder 511 is equipped with an adsorption plate 512. The adsorption plate 512 achieves stable adsorption of the workpiece through air pressure control. An electronic pressure valve gauge 513 is installed on the air pipe 510. The electronic pressure valve gauge 513 precisely adjusts the air pressure to ensure that the adsorption force is moderate and to prevent damage to the workpiece. The lower pressure cylinder 511 moves through the drive seat 54, and the outer wall of the lower pressure cylinder 511 is provided with toothed grooves at equal intervals. The lower pressure cylinder 511 is fitted with a compression spring 514. One end of the compression spring 514 is fixed to the top of the drive seat 54, and the other end is fixedly connected to the head of the lower pressure cylinder 511. Buffer rubber columns 515 are fixedly connected to the top of the drive seat 54 and the head of the lower pressure cylinder 511. The drive base 54 has a gear chamber inside, and a drive gear 517 is installed in the gear chamber. The drive gear 517 meshes with the tooth groove of the lower pressure cylinder 511. The shaft of the drive gear 517 is connected to the output end of the motor 516, which drives the lower pressure cylinder 511 to move up and down, so as to achieve precise positioning of the adsorption plate 512. The motor 516 is installed on the outer surface of the drive base 54.

[0029] When motor 516 starts, drive gear 517 rotates, causing pressure cylinder 511 to move downwards, which in turn causes adsorption plate 512 to adhere tightly to the workpiece surface. Compression spring 514 provides reverse support force. At the same time, air pump 59 starts, and the airflow at the point where adsorption plate 512 is in contact with flat round head bolt is quickly drawn away, forming a negative pressure environment. The flat round head bolt is firmly adsorbed. Electronic pressure valve 513 monitors and fine-tunes the air pressure in real time to form a stable adsorption force. Meanwhile, buffer rubber column 515 effectively reduces shock, protects the workpiece and equipment, and improves overall operational stability and safety.

[0030] In use, the air pump 59 is first started by the control system to quickly draw air and form a negative pressure. The operator holds the flat round head bolt to be ground, and its head surface is firmly adsorbed on the adsorption plate 512. The electronic pressure valve 513 adjusts the air pressure in real time to ensure that the adsorption force is constant and to prevent the bolt from shifting. Then the motor 516 is started, and the drive gear 517 drives the lower pressure cylinder 511 to descend precisely. Thus, the lower pressure cylinder 511 drives the bolt tightly adsorbed by the adsorption plate 512 to descend to the clamping area. Then, the control system starts the motor 314, which drives the gear 312 to rotate. The gear 312 drives the tooth block 310 to move along the slide rail 311, which in turn pushes the moving rod 35 to extend forward in the fixed cylinder 34. The clamping head 37 drives the movable clamping seat 38 to fit tightly against the flat round head bolt. With the tight cooperation with the fixed clamping seat 315, a stable clamping force is formed to ensure that the bolt does not shift during the grinding process and achieves a firm clamping. After clamping, the air pump 59 stops running, the adsorption plate 512 gradually releases negative pressure, the flat round head bolt remains stationary under the clamping force, the motor 3 516 reverses, the drive gear 517 drives the lower pressure cylinder 511 to rise, ensuring that the adsorption plate 512 separates from the bolt, and the entire device enters standby mode, waiting for the next round of operation instructions. Subsequently, the operator confirms the clamping status through the control system. Then, the operator adjusts the progress of the electric grinder 410 through the telescopic cylinder 49. The electric grinder 410 precisely contacts the bolt surface, and the atomizing nozzle 411 progresses synchronously. At the same time, the electric grinder 410 and motor 21 are turned on. Motor 21 drives the pinion 22 to rotate, which in turn drives the large gear 23 and the rotating table 25 to rotate synchronously, thereby causing the bolt to rotate at a uniform speed. (It should be noted that during the rotation of all clamping devices on the rotating table 25, they are not obstructed by the grinding component 4 and the adsorption component 5. The clamping force and rotational force are perfectly matched to ensure uniform grinding without dead angles.) The electric grinder 410 grinds efficiently, and the atomizing nozzle 411 continuously cools down, ensuring that the bolt surface is ground evenly and does not overheat, thereby improving the grinding quality and efficiency. Finally, after the grinding is completed, the operator stops all motors through the control system, the electric grinder 410 resets, the atomizing nozzle 411 stops spraying water, and the clamping head 37 and the movable clamping seat 38 are released synchronously. At this time, the electric telescopic rod 44 is started through the control system. The electric telescopic rod 44 drives the tripod plate 45 to adjust the angle, so that the tripod plate 45 rotates flexibly around the support point connected to the top of the connecting column 46 as the axis. This drives the push rod 48 on the linkage block 47 to move linearly under the limiting action of the limiting block 42. The push rod 48 precisely pushes the bolt out of the clamping area and removes the bolt.
