Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a polishing equipment for processing rivets and studs. Background Technology

[0002] When polishing rivets and studs, magnetic polishing machines are typically used for mass polishing. Magnetic polishing machines generate a magnetic field through high-frequency changes in strong electromagnetic force, driving magnetic abrasives (such as stainless steel studs) to rotate, vibrate, and impact on the workpiece surface at high speed. The friction and impact forces between the abrasives and the workpiece surface remove tiny protrusions, tool marks, and burrs, achieving efficient polishing. Under the influence of the magnetic field, the abrasives move in a circular motion around the workpiece surface, covering the planar area. The rapid changes in the strength and direction of the magnetic field cause the abrasives to vibrate up and down, penetrating into complex areas such as grooves and inner holes. When water is added to the abrasives, it flows under the drive of the magnetic field, constantly changing the contact point with the workpiece to avoid excessive local wear.

[0003] In the prior art, such as the fine polishing device for producing medical sampling forceps disclosed in CN116000795B, there is a main body with a control panel on the front. A limit sleeve is fixedly installed on the top of the main body, and a magnetic polishing barrel is placed on the top of the main body. A drain pipe is fixedly connected to the side of the magnetic polishing barrel. A first drive motor is fixedly installed on the bottom wall of the main body through a fixed seat, and a rotating shaft is fixedly installed at the output end of the first drive motor. By rotating the polishing needles in the magnetic polishing barrel at high speed, the surface of the sampling forceps is ground at high speed and comprehensively. After the magnetic polishing is completed, the polishing liquid is pumped into a water storage tank through an L-shaped tube and a straight tube, which simplifies the drainage operation and saves resources.

[0004] The aforementioned document describes how the polishing fluid can be recycled after magnetic polishing. However, in actual use, traditional magnetic polishing machines lack an integrated screening structure. Even if the polishing fluid is extracted, the filtration process still requires a complex process with additional equipment. Furthermore, the magnetic needles and workpieces inside the polishing cylinder still need to be emptied by the operator, making it impossible to integrate magnetic grinding and filtration, resulting in cumbersome operation.

[0005] Therefore, this invention proposes a polishing device for riveting and rivet post processing to solve the problems of complex structure and limited function of existing polishing devices. Summary of the Invention

[0009] Preferably, the lower part of the cylinder is fixedly installed at the upper end of the bottom of the cylinder, and an annular liquid storage cavity is provided on the inner surface of the lower part of the cylinder. Water inlets are evenly opened on the inner ring sidewall of the annular liquid storage cavity. The bottom end of the water inlet is at the same level as the conical slope of the cone part. An air inlet pipe is connected to the outer ring of one side of the lower part of the cylinder.

[0010] Preferably, the lower end of the upper part of the cylinder is fixedly connected to the upper end of the lower part of the cylinder, and the outer ring surface of the upper part of the cylinder is uniformly provided with slots. The inner surface of the slots is adapted to multiple sets of fixed clamping blocks.

[0011] Preferably, the inner surface of the insert block is provided with a T-shaped groove, and the two ends of the T-shaped groove are fixedly installed with clamping arms. The clamping arms are in the shape of an "L" plate, and the end of the clamping arm near the fixed clamping block is provided with a hook foot.

[0012] Preferably, the inner walls of both ends of the fixed mounting block are respectively provided with mounting grooves, and a reserved groove is provided through the inner side of the mounting groove. An elastic abutment block is fixedly connected to the inner side of the reserved groove. The elastic abutment block has a "U"-shaped block structure, and the outer surface of the elastic abutment block is in movable contact with the outer surface of one end of the mounting arm.

[0013] Preferably, a central piston hole is provided on the inner wall of the fixed mounting block, and a piston rod is movably installed on the inner surface of the central piston hole. The piston rod is composed of a piston plate, a rod body, and a push block. The outer surface of the rod body is slidably connected to the inner wall of the fixed mounting block, and a spring is slidably sleeved on the outer surface of the rod body. One end of the spring is fixedly connected to the inner surface of the piston plate, and the other end of the spring is fixedly connected to the inner wall of the central piston hole.

[0014] Preferably, a pin is rotatably connected to the inner wall of the insert block on the side away from the fixed mounting block.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention proposes a polishing device for riveting and rivet post processing. By employing an inner conical bottom at the bottom of the polishing inner cylinder that mates with the bottom of the inner cylinder, the device effectively seals the holes at the bottom of the inner conical bottom. The fitting design between the bottom of the inner cylinder and the bottom of the polishing inner cylinder ensures stability during workpiece rotation during polishing, preventing swaying of the steel column within the inner cylinder at high speeds and improving equipment reliability. Furthermore, the optimized design of the conical structure disrupts the movement trajectory of the steel column, causing multi-directional collisions and friction between the steel column and the workpiece. The conical bottom design guides the magnetic needles towards the center, improving grinding efficiency. When the polishing inner cylinder is raised, the inner conical bottom is exposed, acting as a filter structure to allow the polishing fluid to flow out through the circular holes, while the steel column is retained within the inner cylinder. This integrated polishing and filtration design further enhances polishing efficiency and quality. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figure 1-18This invention provides a technical solution: a polishing device for riveting and rivet post processing, including a magnetic polishing machine 1. The upper end of the magnetic polishing machine 1 is provided with an operating platform 11, and a disk assembly is provided below the operating platform 11. The disk assembly consists of a motor and a disk, and multiple electromagnets are mounted on the disk. When the electromagnet coil is energized, a magnetic field is generated, allowing the disk to rotate at high speed and drive the steel posts to rotate together, thus polishing the workpiece surface. The upper end of the operating platform 11 is provided with a polishing outer cylinder 2, which consists of an upper cylinder 21, a lower cylinder 22, and a bottom cylinder 23. The lower end of the upper cylinder 21 is fixedly connected to the upper end of the lower cylinder 22. The lower cylinder 22 is fixedly installed on the upper end of the bottom cylinder 23, and an annular liquid storage cavity 220 is provided on the inner surface of the lower cylinder 22. Water inlets are evenly distributed on the inner annular sidewall of the annular liquid storage cavity 220. The inlet 2200 has its bottom end level with the conical slope of the cone-shaped body. An air inlet pipe 221 is connected to the outer ring of one side of the lower part 22 of the cylinder, and a liquid extraction system is connected to the output end of the air inlet pipe 221. The bottom 23 of the cylinder is integrally formed from a circular plate and a cone-shaped body. A threaded protrusion 231 is threaded onto the upper surface of the cone-shaped body, with a rounded upper end. A polished inner cylinder 3 is provided inside the polished outer cylinder 2, and an inner conical bottom 31 is provided at the bottom end of the polished inner cylinder 3. The lower outer surface of the inner conical bottom 31 matches the upper surface of the bottom 23 of the cylinder. Circular holes 310, which match the threaded protrusions 231, are evenly distributed on the inner conical bottom 31, and silicone collars are fixedly installed inside the circular holes 310. A retaining ring mechanism is provided on the outer ring surface of the upper part 21 of the cylinder, and the retaining ring mechanism includes a sleeve air pipe 4. Please refer to this carefully. Figure 2 , Figures 4-8When polishing rivets, the inner polishing cylinder 3 and the outer polishing cylinder 2 are first assembled. It should be noted that an installation mechanism is provided at the top of the upper part 21 of the cylinder. This mechanism includes a knob, a threaded rod, and a limiting rod. The outer surface of the threaded rod is threaded to the inner wall of the upper outer edge of the inner polishing cylinder 3, and the outer surface of the limiting rod is slidably connected to the inner wall of the upper outer edge of the inner polishing cylinder 3. When installing the inner polishing cylinder 3, the knob is manually rotated until the concave cone of the bottom inner cone 31 of the inner polishing cylinder 3 aligns with the upper side of the bottom 23 of the cylinder. At this point, the threaded protrusion 231 corresponds one-to-one with the circular hole 310, and the hole at the bottom of the inner cone 31 is sealed. Then, steel columns, rivets to be polished, and a mixture are poured into the inner polishing cylinder 3, and the disk assembly is opened. The steel columns, under the influence of the magnetic field, rotate around the workpiece surface, covering... In the planar area, rapid changes in the strength and direction of the magnetic field cause the abrasive to vibrate up and down. It is worth noting that the mating structure between the threaded protrusion 231 at the bottom of the cylinder 23 and the inner conical bottom 31 at the bottom of the polishing inner cylinder 3 can form a three-dimensional grinding surface, causing the steel column and the workpiece to move in multiple directions under disturbance, thus improving the polishing effect. Secondly, the threaded protrusion 231 will disturb the movement trajectory of the steel column, causing the steel column and the workpiece to collide and rub in multiple directions, which conforms to the polishing principle of "high-frequency impact + sliding friction" of magnetic abrasive. The conical bottom design of the inner conical bottom 31 can guide the steel column to converge towards the center, improving the grinding efficiency. It is worth noting that the diameter of the circular hole 310 here is larger than the diameter of the steel column, so that the steel column will not fall into the circular hole 310 and will not cause blockage of the circular hole 310. In addition, the threaded protrusion 231 and the bottom of the cylinder 23 are connected by threads, which facilitates disassembly and replacement after wear.

[0022] Example 2, see attached document Figure 1-18 Based on Example 1, in order to achieve auxiliary stability after the polished inner cylinder 3 is installed and to avoid large swaying caused by the high-speed rotation of the steel column: The lower part 22 of the cylinder has an annular cavity on its inner surface. An auxiliary stabilizing mechanism is provided inside the annular cavity, including a fixing block 41, an inserting block 42, and an annular retaining ring 43. The upper part 21 of the cylinder has evenly spaced slots 210 on its outer annular surface. The inner surface of each slot 210 is adapted to multiple sets of fixing blocks 41. Each fixing block 41 has a slot on its inner side, and the inner surface of the slot is movably inserted into the outer surface of one end of the inserting block 42. The inner surface of the inserting block 42 has a T-shaped groove 420, and fixing arms 421 are fixedly installed at both ends of the T-shaped groove 420. The fixing arms 421 have an "L"-shaped plate structure, and a hook is provided at the end of the fixing arm 421 closest to the fixing block 41. Fixing grooves 41 are respectively provided on the inner walls of both ends of the fixing block 41. 0. A reserved groove 4100 is provided through the inner side of the mounting groove 410. An elastic abutment block 4101 is fixedly connected to the inner side of the reserved groove 4100. The elastic abutment block 4101 has a "U"-shaped block structure, and the outer surface of the elastic abutment block 4101 is in movable contact with the outer surface of one end of the mounting arm 421. A pin is rotatably connected to the inner wall of the insert block 42 away from the fixed mounting block 41. The outer surface of the pin is fixedly connected to one end of the annular retaining ring 43, and torsion springs are slidably sleeved between the two ends of the pin and the annular retaining ring 43. The inner surface of the annular retaining ring 43 is in movable contact with the outer surface of the polishing inner cylinder 3. A steel ball 431 is rotatably installed on the side of the annular retaining ring 43 near the outer ring surface of the polishing inner cylinder 3. The outer surface of the steel ball 431 is in rolling contact with the outer ring side wall of the polishing inner cylinder 3. refer to Figure 2 , Figure 9 and Figure 13 As shown, before combining the inner polishing cylinder 3 and the outer polishing cylinder 2, the auxiliary stabilizing mechanism is assembled with the upper cylinder 21. The fixing block 41 is adapted to the slot 210. The fixing block 41 is arranged in an array about the central axis of the upper cylinder 21, which can provide structural strength support for the outer periphery of the upper cylinder 21. When engaging the inserting block 42, the end of the inserting block 42 away from the annular ring 43 is aligned with the slot of the fixing block 41. During the fitting and insertion process, the two sets of clamping arms 421 are inserted into the clamping slots 410. The rounded ends of the elastic contact blocks 4101 abut against the side walls of the clamping arms 421, generating compression. When the hooks of the clamping arms 421 are fully extended from the clamping slots 410, the elastic contact blocks 4101 apply pressure to the clamping arms 421, thus automating the clamping of the inserting blocks 42. After multiple sets of inserting blocks 42 are connected to the fixed clamping blocks 41, the support strength of the annular cavity structure in the upper part 21 of the cylinder can be increased; as shown in the attached... Figure 15As shown, adjacent annular retaining rings 43 overlap end to end. After the polishing inner cylinder 3 is combined with the upper part 21 of the cylinder, multiple sets of annular retaining rings 43 form an annular structure to clamp the outer ring of the polishing inner cylinder 3, further improving its stability during polishing.

[0023] Example 3, refer to Appendix Figure 1-18 Based on Example 2, in order to achieve auxiliary shaking of the internal mixture by each annular retaining ring 43 after the inner polishing cylinder 3 is lifted: The inner ring surface of the sleeve air duct 4 is fixedly connected to the outer ring surface of the upper part 21 of the cylinder by bolts. The inner surface of the sleeve air duct 4 is provided with an annular air cavity. The inner ring surface of the annular air cavity is provided with air guide holes 401 evenly, and the air guide holes 401 correspond one-to-one with the central piston hole 41000. The inner ring surface of the sleeve air duct 4 is provided with mating grooves 400 evenly, and the inner surface of the mating grooves 400 is movably connected to the outer surface of the fixed clamping block 41. A central piston hole 41000 is provided on the inner wall of the fixed mounting block 41. A piston rod 41001 is movably installed on the inner surface of the central piston hole 41000. The piston rod 41001 is composed of a piston plate, a rod body, and a push block. The outer surface of the rod body is slidably connected to the inner wall of the fixed mounting block 41. A spring 41002 is slidably sleeved on the outer surface of the rod body. One end of the spring 41002 is fixedly connected to the inner surface of the piston plate, and the other end of the spring 41002 is fixedly connected to the inner wall of the central piston hole 41000. refer to Figures 15-18 As shown, a sleeve-type air duct 4 is installed on the outer ring of the upper part 21 of the cylinder. The inner mating groove 400 is adapted to the width of the fixing block 41, and the position of the air guide hole 401 corresponds one-to-one with the input port of the central piston hole 41000. The sleeve-type air duct 4 is fixed to the outer wall of the upper part 21 of the cylinder by bolts. When compressed gas is introduced into the annular air cavity inside the sleeve-type air duct 4 through the air inlet pipe 40, the gas flows through the annular air cavity and enters through multiple central piston holes 41000. At this time, the compressed gas pushes the piston rod 41001 inside the central piston hole 41000, causing the spring 41002 to compress. At the same time, the piston rod 41001... The pusher pushes one end of another set of annular rings 43 that are adjacent to the interlocking block 42. Due to the uneven distribution of compressed gas in the annular air cavity, the swing amplitude of each annular ring 43 is different. When the annular ring 43 swings inward, the steel ball 431 on the inner side of the annular ring 43 continuously knocks on the outer wall of the polishing inner cylinder 3, accelerating the sieving of the mixed liquid inside the polishing inner cylinder 3. When compressed gas is no longer introduced into the inner cylinder, the multiple sets of annular rings 43 are attached end to end, which can serve as a compensation structure for the inner ring surface of the upper part 21 of the cylinder, ensuring that the polishing inner cylinder 3 will not be splashed into the slot 210 when it is lifted upward, thus achieving the function of protection. It is worth noting that the connecting duct 4 here can not only enhance the strength of the outer ring structure of the upper part 21 of the cylinder, but also supply compressed gas, achieving the effect of "one ring for multiple uses".

[0024] The working principle and usage process of this invention are as follows: In actual use, step one is to assemble the inner polishing cylinder 3 and the outer polishing cylinder 2. The inner polishing cylinder 3 is assembled with the outer polishing cylinder 2 through the installation mechanism. The knob is manually rotated to lower the inner polishing cylinder 3 until the bottom conical bottom 31 is fitted with the upper side of the bottom 23 of the cylinder, and the screw-in protrusion 231 corresponds one-to-one with the round hole 310. Step two is to install the auxiliary stabilizing mechanism: Before assembling the inner polishing cylinder 3 and the outer polishing cylinder 2, the fixing and locking block 41 of the auxiliary stabilizing mechanism is fitted and inserted into the slot 210 of the upper part 21 of the cylinder, and then the inserting block 42 is inserted into the slot of the fixing and locking block 41 to achieve automated locking. Multiple sets of annular retaining rings 43 are used. The ring structure clamps the outer ring of the polishing inner cylinder 3 to improve stability; Step 3: Add materials and start polishing: Pour steel columns, rivet columns to be polished and mixed liquid into the polishing inner cylinder 3, control the disk assembly to open, so that the steel columns move in a circle around the surface of the workpiece under the action of the magnetic field to polish; Step 4: Achieve mixed liquid-assisted shaking: After polishing, when the mixed liquid is separated from the steel columns and the workpiece, the polishing inner cylinder 3 is raised to a certain height, and compressed gas is introduced into the annular air cavity inside the sleeve air pipe 4 through the air inlet pipe 221. The gas pushes the piston rod 41001, causing the annular clamping ring 43 to swing, and the inner steel balls 431 knock on the outer wall of the polishing inner cylinder 3 to accelerate the screening of the internal mixed liquid.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
