Description

Technical Field

[0001] This utility model relates to the field of burr removal technology, and in particular to a burr removal device for high-precision fasteners. Background Technology

[0002] In the field of precision manufacturing, high-precision fasteners are widely used in aerospace, automotive, and precision instrument industries, where reliability requirements are extremely high. The surface quality and dimensional accuracy of these fasteners directly affect their connection performance, fatigue strength, and the overall safety of the equipment. However, during their machining process, microscopic burrs are inevitably generated at edges or openings. If these burrs are not removed, they may not only affect assembly accuracy and fit, but may also cause premature component failure due to stress concentration during service, or detach and become wear particles, endangering system operation. Therefore, deburring is a crucial step in the post-processing of high-precision fasteners. Currently, magnetic polishing (also known as magnetic abrasive polishing) technology has become a common choice in the industry for meeting the demand for efficient, uniform, and non-damaging deburring of such parts. This technology uses a magnetic field to drive magnetic abrasives to form a flexible "abrasive brush" that grinds the surface of the part immersed in polishing fluid from all directions, effectively removing burrs and improving surface finish, and is especially suitable for fasteners with complex structures and numerous micropores.

[0003] However, existing magnetic polishing equipment still has significant operational shortcomings in practical use, mainly in the post-polishing processing stage. Specifically, after the polishing process is completed, the container (such as a polishing tank) containing a mixture of fasteners and a large amount of polishing fluid needs to be moved to a separation station. Currently, the common method is for operators to manually lift the heavy container as a whole, or to pour it over to transfer the polishing fluid and fasteners together to a separate vibrating separator or filter to separate the solid parts from the liquid polishing medium. This process is not only time-consuming, labor-intensive, and inefficient, but also prone to splashing and wasting polishing fluid during the pouring process, increasing production costs and the burden of on-site cleanup.

[0004] To address this, we propose a high-precision fastener deburring device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision fastener burr removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a burr removal device for high-precision fasteners, comprising a magnetic polishing machine body and a polishing cylinder, wherein a pneumatic push assembly is fixedly installed on the front outer wall of the magnetic polishing machine body, and both movable ends of the pneumatic push assembly are fixedly connected to a slide block, and the slide block is slidably connected to the magnetic polishing machine body;

[0007] The top of each of the two slides is fixedly connected to a bracket, and the two brackets are fixedly connected to an assembly base. The top of the assembly base is fixedly connected to a first cylinder, and the movable end of the first cylinder passes through the assembly base and is fixedly connected to a movable frame. The inner walls on both sides of the movable frame are rotatably fitted with support rings, and the support rings are fixedly fitted to the outer surface of the polishing cylinder.

[0008] A pneumatic push-pull assembly is installed between the support ring and the mounting base.

[0009] Furthermore, the pneumatic propulsion assembly includes a second cylinder, and the cylinder body of the second cylinder is fixedly connected to the main body of the magnetic polishing machine. The movable end of the second cylinder is fixedly connected to an arc-shaped frame, and the arc-shaped frame is fixedly connected to two slide blocks. This structure synchronously drives the slide blocks on both sides through a single power source, realizing the linear motion of the polishing cylinder moving out and returning to its original position.

[0010] Furthermore, the bottoms of the two slides are slidably connected to guide rails, and the two guide rails are symmetrically fixed to the top of the magnetic polishing machine body. The guide rails provide movement guidance and stable support for the slides and the polishing cylinder they support.

[0011] Furthermore, the top of the movable frame is symmetrically and fixedly connected with two guide rods, which pass through adjacent supports and are slidably connected to the adjacent supports. The guide rods ensure that the movable frame maintains vertical and stable movement during the lifting and lowering process.

[0012] Furthermore, the pneumatic push-pull assembly includes a third cylinder, and the cylinder body of the third cylinder is rotatably connected to the inner walls on both sides of the mounting base. A connecting block is fixedly connected to the movable end of the third cylinder, and a long rod is rotatably connected to the inner walls on both sides of the connecting block. The long rod is fixedly connected to the outer surface of the support ring. This design directly drives the support ring to rotate through the cylinder push-pull, thereby controlling the tilting and straightening angle of the polishing cylinder.

[0013] Furthermore, the polishing cylinder is internally fitted with a mesh basket, which can separate fasteners when there are many fasteners that need to be deburred, thereby improving the deburring effect.

[0014] The beneficial effects of this utility model are:

[0015] In use, this utility model utilizes a first cylinder to control the lifting and lowering of the movable frame and support ring. Then, a pneumatic push assembly drives the slide to move the bracket and assembly seat, removing the polishing cylinder from the main body of the magnetic polishing machine. Combined with a pneumatic push-pull assembly, the support ring and polishing cylinder are tilted, achieving automated transfer and dumping of fasteners and polishing fluid after polishing. This effectively avoids the problems of low efficiency, high labor intensity, and waste of polishing fluid caused by manual handling of containers in the prior art. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, a burr removal device for high-precision fasteners is disclosed, comprising a magnetic polishing machine body 1 and a polishing cylinder 3. A pneumatic push assembly is fixedly installed on the front outer wall of the magnetic polishing machine body 1. Both movable ends of the pneumatic push assembly are fixedly connected to slide blocks 13, and the slide blocks 13 are slidably connected to the magnetic polishing machine body 1. The pneumatic push assembly includes a second cylinder 11, and the cylinder body of the second cylinder 11 is fixedly connected to the magnetic polishing machine body 1. An arc-shaped frame 12 is fixedly connected to the movable end of the second cylinder 11, and the arc-shaped frame 12 is fixedly connected to two slide blocks 13. The bottom of the two slide blocks 13 is slidably connected to a guide rail 2, and the two guide rails 2 are symmetrically fixedly connected to the top of the magnetic polishing machine body 1. The guide rails 2 have a limiting function for the slide blocks 13, which can ensure the stability of the movement of the slide blocks 13.

[0024] Each of the two slide blocks 13 has a bracket 9 fixedly connected to its top. The two brackets 9 are connected together by an assembly base 14. The top of the assembly base 14 is fixedly connected to a first cylinder 7, and the movable end of the first cylinder 7 passes through the assembly base 14 and is fixedly connected to a movable frame 5. The inner walls of both sides of the movable frame 5 are rotatably fitted with support rings 10, and the support rings 10 are fixedly fitted on the outer surface of the polishing cylinder 3. The top of the movable frame 5 is symmetrically fixedly connected to two guide rods 6, and the guide rods 6 pass through the adjacent brackets 9 and are slidably connected to the adjacent brackets 9. The support rings 10 and the movable frame 5 are rotatably connected through two existing bearing seats. The bearing seats are fixed to the movable frame 5, and the inner ring of the bearing inside the bearing seat is fixedly fitted on the mounting shafts on both sides of the support ring 10.

[0025] A pneumatic push-pull assembly is installed between the support ring 10 and the mounting base 14. The pneumatic push-pull assembly includes a third cylinder 8, and the cylinder body of the third cylinder 8 is rotatably connected to the inner walls on both sides of the mounting base 14. A connecting block 16 is fixedly connected to the movable end of the third cylinder 8. A long rod 15 is rotatably connected to the inner walls on both sides of the connecting block 16, and the long rod 15 is fixedly connected to the outer surface of the support ring 10. A mounting shaft is fixedly connected to both sides of the third cylinder 8. The mounting shaft passes through the inner wall of the mounting base 14 and is rotatably connected to the mounting base 14, thereby realizing the rotatable connection between the mounting base 14 and the third cylinder 8. The connecting block 16 and the long rod 15 are rotatably connected through an existing pin.

[0026] The polishing barrel 3 is equipped with a mesh basket 4 inside. The mesh basket 4 is an auxiliary item. When there are many fasteners that need to be deburred, the fasteners can be separated to improve the deburring effect.

[0027] The first cylinder 7, the second cylinder 11, and the third cylinder 8 are all electrically connected to the controller used in the magnetic polishing machine, and the controller controls the operation of the three cylinders.

[0028] Working principle: The operator places the high-precision fastener to be processed, along with magnetic abrasive and polishing fluid, into the grid basket 4 inside the polishing cylinder 3. Then, the main body 1 of the magnetic polishing machine is started, which generates an alternating magnetic field, driving the magnetic abrasive to grind the surface of the fastener and remove burrs.

[0029] After the polishing process is completed, the main body 1 of the magnetic polishing machine stops working. At this time, the first cylinder 7, which is fixed to the top of the mounting base 14, is activated. The movable end of the first cylinder 7 retracts upward, pulling the movable frame 5 up a short distance. The movable frame 5, through the support rings 10 that are rotatably sleeved on its inner walls on both sides, drives the polishing cylinder 3 to rise as a whole, so that its bottom is disengaged from the worktable of the main body 1 of the magnetic polishing machine. The guide rod 6 at the top of the movable frame 5 slides along the bracket 9 to ensure stability during the lifting process.

[0030] The pneumatic drive assembly is activated, and the second cylinder 11 in the assembly extends its movable end, pushing the arc-shaped frame 12 fixed thereto forward. The arc-shaped frame 12 drives the two slide blocks 13 to slide synchronously along the guide rail 2 fixed to the top of the magnetic polishing machine body 1, thereby moving the entire moving mechanism, consisting of the slide blocks 13, the support 9, the mounting base 14, etc., along with the polishing cylinder 3 it carries, out of the working area of ​​the magnetic polishing machine body 1 and to the predetermined separation station.

[0031] Subsequently, the pneumatic push-pull assembly is activated, and the movable end of the third cylinder 8 in the assembly retracts, pulling the connecting block 16 fixed thereto. The connecting block 16 drives the long rod 15, which is rotatably connected thereto, to move. Since the long rod 15 is fixedly connected to the support ring 10, the support ring 10 is forced to rotate within the movable frame 5.

[0032] The rotation of the support ring 10 directly causes the polishing cylinder 3, which is fixedly sleeved thereon, to tilt. When the polishing cylinder 3 tilts, the polishing liquid and the fasteners are poured together into the solid-liquid separation device, thereby achieving effective separation of the fasteners and the polishing liquid. The whole process is splash-free.

[0033] After separation, each component is reset.
