Description

Technical Field

[0001] This utility model relates to the field of precision machining technology, specifically to a precision component deburring and polishing equipment. Background Technology

[0002] In the field of precision machining, deburring and polishing processes have a significant impact on the surface quality, dimensional accuracy, and service life of workpieces, especially in high-value-added industries such as aerospace, medical devices, and optical components, where requirements for surface roughness and edge integrity are extremely stringent. Traditional polishing equipment typically uses a polishing disc that rotates at a fixed height, resulting in a relatively stationary contact area with the workpiece. This can easily lead to over-removal of material in certain areas (such as over-grinding in the central region) or insufficient polishing of the edges, resulting in uneven surfaces. Furthermore, the continuous, fixed contact pressure can raise the temperature of the polishing area, which, especially for heat-sensitive materials such as aluminum alloys and titanium alloys, can cause changes in the surface microstructure and even thermal stress deformation. Therefore, there is an urgent need for a precision component deburring and polishing equipment. Utility Model Content

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes a base 1, a rotating cylinder 2, a connecting rod 3, and a polishing disc 4. The rotating cylinder 2 is rotatably inserted through the top of the base 1 via a bearing. The connecting rod 3 is movably inserted inside the rotating cylinder 2. The polishing disc 4 is fixedly installed at the upper end of the connecting rod 3. Several guide strips 22 are distributed on the connecting rod 3 with equal rounded corners. The guide strips 22 are movably inserted into the strip grooves 23 opened on the inner wall of the rotating cylinder 2. The guide strips 22 can not only improve the structural strength of the connecting rod 3, but also provide auxiliary guidance for the movement of the connecting rod 3 in the rotating cylinder 2, thereby improving the movement stability of the connecting rod 3. A protective cover 24 is fixedly installed on the upper part of the base 1, and the protective cover 24 covers the polishing disc 4. The protective cover 24 provides a certain degree of protection on the outside of the polishing disc 4, avoiding the random splashing of debris generated during the polishing process, which seriously affects the processing environment.

[0029] It also includes:

[0030] The self-locking motor 5 is fixedly installed on the bottom right side of the base 1. A drive rod 6 is rotatably installed in the base 1 through a bearing. The output shaft of the self-locking motor 5 is connected to the drive rod 6. Spur gears 7 are fixedly sleeved on both the rotating cylinder 2 and the drive rod 6. The two spur gears 7 are meshed together.

[0031] The lifting rod 8 is movably inserted into the rotating cylinder 2. The upper end of the lifting rod 8 is rotatably inserted into the lower end of the connecting rod 3 through a bearing. The lower end of the lifting rod 8 is hinged to a connecting rod 9, and the lower end of the connecting rod 9 is hinged to a slider 10.

[0032] The driven rod 11 is rotatably mounted on the left side of the bottom wall of the base 1 via a bearing. A rotating disk 12 is fixedly mounted on the upper end of the driven rod 11. A slider 10 is slidably mounted in a groove 13 opened on the upper part of the rotating disk 12. An adjustment mechanism 14 connected to the slider 10 is provided on the rotating disk 12. A support frame 21 is fixedly mounted on the rotating disk 12 and is fixedly mounted in the base 1. The support frame 21 can provide auxiliary support for the rotating disk 12, thereby effectively improving the rotational stability of the rotating disk 12.

[0033] Synchronous pulley 15 is fixedly sleeved on drive rod 6, and synchronous pulley 16 is fixedly sleeved on driven rod 11. Synchronous pulley 15 and synchronous pulley 16 are connected by synchronous belt 17.

[0034] The adjustment mechanism 14 includes:

[0035] Threaded rod 14-1, which is rotatably mounted in rotating disk 12 and sliding groove 13 via bearing, and slider 10 is rotatably mounted on threaded rod 14-1 via thread;

[0036] The control rod 14-2 is rotatably inserted into the driven rod 11 via a bearing. The upper end of the control rod 14-2 is rotatably inserted into the rotating disk 12 via a bearing. A first bevel gear 14-3 is fixedly sleeved on the upper end of the control rod 14-2. A second bevel gear 14-4, which meshes with the first bevel gear 14-3, is fixedly sleeved on one end of the threaded rod 14-1. An adjustment handle 14-5 is connected to the lower end of the control rod 14-2 via a limiting mechanism 18. The control rod 14-2 can drive the first bevel gear 14-3 to rotate. By utilizing the meshing of the first bevel gear 14-3 and the second bevel gear 14-4, the rotation of the threaded rod 14-1 can be controlled, thereby adjusting the position of the slider 10 in the slide groove 13. This changes the distance between the lower end of the connecting rod 9 and the center of the rotating disk 12, thus adjusting the up-and-down reciprocating distance of the lifting rod 8, the connecting rod 3, and the polishing disk 4 during the rotation of the rotating disk 12.

[0037] The limiting mechanism 18 includes:

[0038] The fixed ring 18-1 is fixedly sleeved on the control rod 14-2, and the fixed ring 18-1 is located in the cylindrical groove 19 opened at the lower end of the driven rod 11. The adjusting handle 14-5 is movably inserted into the cylindrical groove 19, and a spring 18-2 is connected between the adjusting handle 14-5 and the fixed ring 18-1.

[0039] Ribs 18-3, several of which are evenly distributed on the control rod 14-2 with rounded corners, are movably inserted into the adjusting handle 14-5 at the lower end of the control rod 14-2 and the ribs 18-3. A connecting ring 18-4 is fixedly sleeved on the lower end of the driven rod 11 at the position below the base 1. Several limiting teeth 18-5 are evenly distributed on the adjusting handle 14-5 with rounded corners. The limiting teeth 18-5 are engaged in the tooth grooves 20 opened on the connecting ring 18-4. The pulling force applied to the adjusting handle 14-5 by the spring 18-2 can make the adjusting handle 14-5 drive the limiting teeth 18-5 to abut against the tooth grooves 20, thereby restricting the rotation of the adjusting handle 14-5 on the driven rod 11 and preventing the adjusting handle 14-5 and the control rod 14-2 from rotating during the rotation of the driven rod 11.

[0040] When using this invention, the self-locking motor 5 can be started, which drives the drive rod 6 to rotate. The meshing of two spur gears 7 causes the rotating cylinder 2 to rotate. The rotating cylinder 2, through the connecting rod 3, drives the polishing disc 4 to rotate, thus polishing the workpiece. During this process, the cooperation of the first synchronous pulley 15, the second synchronous pulley 16, and the synchronous belt 17 also enables the driven rod 11 to rotate. The driven rod 11 drives the rotating disc 12 to rotate. The rotating disc 12, through the slider 10 and the connecting rod 9, drives the lifting rod 8 to move up and down reciprocally. The lifting rod 8, through the connecting rod 3, drives the polishing disc 4 to move up and down reciprocally, effectively improving the uniformity of burr polishing on the workpiece. Adjustments can be made according to the polishing surface range of different workpieces. At the same time, the adjusting handle 14-5 can be pulled down, so that the spring 18-2 is stretched and the limiting tooth 18-5 disengages from the tooth groove 20. Then, the adjusting handle 14-5 is rotated, and the adjusting handle 14-5 drives the control rod 14-2 to rotate through the rib 18-3. The control rod 14-2 drives the first bevel gear 14-3 to rotate, the first bevel gear 14-3 drives the second bevel gear 14-4 to rotate, and the second bevel gear 14-4 drives the threaded rod 14-1 to rotate. The position of the slider 10 in the slide groove 13 is adjusted, and the distance between the lower end of the connecting rod 9 and the center of the rotating disk 12 is changed. This adjusts the range of up and down reciprocating movement of the lifting rod 8, the connecting rod 3 and the polishing disk 4 when the rotating disk 12 is rotating, so as to adapt to the polishing surface range of different workpieces.

[0041] Compared with the prior art, the beneficial effects of this utility model are:

[0042] By cooperating with the rotating cylinder 2, connecting rod 3, self-locking motor 5, drive rod 6, spur gear 7, lifting rod 8, connecting rod 9, slider 10, driven rod 11 and rotating disk 12, the polishing disk 4 can move up and down synchronously during rotation, which can not only improve the polishing uniformity of the workpiece, but also avoid local wear and cutting heat accumulation on the workpiece, thereby effectively improving the burr polishing accuracy of the workpiece.

[0043] By cooperating with the adjustment mechanism 14, and utilizing the transmission of the control rod 14-2, the first bevel gear 14-3, and the second bevel gear 14-4, the rotation of the threaded rod 14-1 can be achieved, changing the position of the slider 10 in the slide groove 13. While adjusting the distance between the lower end of the connecting rod 9 and the center of the rotating disk 12, the up-and-down reciprocating distance of the lifting rod 8, the connecting rod 3, and the polishing disk 4 during the rotation of the rotating disk 12 can also be adjusted.

[0044] With the cooperation of the limiting mechanism 18, the tension applied by the spring 18-2 to the adjusting handle 14-5 can drive the limiting tooth 18-5 to abut against the tooth groove 20, thereby limiting the rotation of the adjusting handle 14-5 on the driven rod 11 and preventing the adjusting handle 14-5 and the control rod 14-2 from rotating during the rotation of the driven rod 11.

[0045] The protective cover 24 can provide a certain degree of protection on the outside of the polishing disc 4, preventing debris generated during the polishing process from flying around and seriously affecting the processing environment.

[0046] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
