Description

Technical Field

[0001] The utility model relates to the technical field of polishing and grinding, in particular to a high-precision polishing device for castings. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then the workpiece is formed after cooling. After the casting is cast, the surface of the workpiece will be relatively rough and there will be burrs on the edges. In order for the workpiece to be able to be further used, it needs to be polished during the processing of the casting.

[0003] For example, prior art publication CN220051320U discloses a high-precision polishing device for castings. The device comprises a workbench and a protective box fixed to the back of the workbench. A rotating shaft is rotatably connected to the workbench, a support plate is fixedly connected to the top of the rotating shaft, and a positioning sleeve for securing cylindrical automotive castings is fixedly connected to the surface of the support plate. Both outer walls of the positioning sleeves have movable holes, and push rods are slidably connected to the movable holes of the positioning sleeves. A stepper motor is mounted on the bottom wall of the inner cavity of the protective box. The output end of the stepper motor is fixedly connected to a lifting screw. Two connecting rods are threadedly connected to the outer wall of the lifting screw. A soundproof cover is fixedly connected to the outer wall of one connecting rod. This device can secure cylindrical automotive castings of different specifications and reduce noise during grinding and polishing.

[0004] For example, the prior art device described above can polish workpieces, but each time a surface of the workpiece is polished, it requires clamping to ensure that the surface to be polished contacts the polishing sheet. This multiple clamping operation can easily affect the polishing accuracy, making it difficult to ensure a satisfactory polishing result. In light of this, we propose a high-precision polishing device for castings. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 5As shown, a high-precision polishing device for castings includes: a base 1, with adjustment assemblies 2 respectively provided on both sides of the top of the base 1, and a bearing seat 3 respectively provided above each group of adjustment assemblies 2. A clamping rod 4 is rotatably mounted on the bearing seat 3 on one side, and a telescopic rod 5 is rotatably mounted on the bearing seat 3 on the other side. A clamping plate 6 is respectively mounted on the inner end of the clamping rod 4 and the telescopic end of the telescopic rod 5; a gantry 7 is also installed above the base 1, and an adjustment assembly 8 is provided on the gantry 7. A telescopic rod 9 is connected to one side of the adjustment assembly 8, and a polishing assembly 10 is provided at the telescopic end of the telescopic rod 9;

[0024] When grinding and polishing a casting, two surfaces of the workpiece are selected as clamped surfaces, and the clamping plates 6 are used to clamp and position the workpiece. During clamping, the workpiece is clamped and positioned by extending the telescopic rod 1 5 to drive the clamping plate 6 thereon to approach the clamping plate 6 on the clamping rod 4. After clamping, the polishing assembly 10 is driven downward by extending the telescopic rod 2 9 to move downward to contact the surface of the workpiece for grinding. During the grinding process, the relative position between the polishing assembly 10 and the workpiece can be changed by adjusting the adjustment assembly 1 2 and the adjustment assembly 2 8, so that different positions on the surface of the workpiece can be ground, thereby achieving comprehensive grinding.

[0025] By extending and retracting the telescopic rod 5, the two clamping plates 6 are driven to move relative to each other to clamp the workpiece, and the telescopic rod 5 and the clamping rod 4 are respectively rotatably connected to the bearing seat 3. During grinding, after grinding one side of the workpiece is completed, the workpiece can be rotated by rotating the telescopic rod 5 and the clamping rod 4 on the bearing seat 3 to replace the grinding surface. It can be achieved that multiple surfaces of the workpiece can be ground by clamping on one side, avoiding multiple clamping to affect the grinding accuracy.

[0026] See also Figure 3 As shown, the adjustment assembly 2 includes a slide rail 21 fixedly mounted on the base 1, a slider 22 is slidably provided on the inner side of the slide rail 21, and a screw rod 23 is rotatably provided on the inner side of the slide rail 21, and the screw rod 23 and the slider 22 are threadedly engaged, one end of the screw rod 23 is connected to a drive motor 24, and the bearing seat 3 is mounted on the slider 22;

[0027] The adjustment of the adjustment component 2 is mainly achieved by driving the motor 24 to drive the screw rod 23 to rotate. The screw rod 23 and the slider 22 are engaged with each other through the thread. The slider 22 can be driven to move in the slide rail 21. The movement of the slider 22 drives the bearing seat 3 to adjust its position left and right, thereby driving the position adjustment between the clamped workpiece and the polishing component 10, which is convenient for polishing different positions of the workpiece. Moreover, the movement of the sliders 22 on the two sets of adjustment components 2 is synchronized.

[0028] See also Figure 2 As shown, the outer end of the clamping rod 4 is connected to a servo motor 41, and the outer housing of the servo motor 41 is fixedly connected to the bearing seat 3;

[0029] After the workpiece is clamped, the servo motor 41 drives the clamping rod 4 to rotate on the bearing seat 3. The rotation of the clamping rod 4 drives the clamped workpiece to rotate, so that the workpiece can be rotated and turned over, and multiple surfaces of the workpiece can be polished and ground in one clamping. Since the clamping rod 4 and the telescopic rod 5 clamp the workpiece together, when the clamping rod 4 rotates, it will drive the telescopic rod 5 to rotate together.

[0030] The clamping surface of the clamping plate 6 is provided with anti-skid patterns. Providing the anti-skid patterns on the clamping surface of the clamping plate 6 can increase the friction with the workpiece, making it easier to clamp the workpiece.

[0031] See also Figure 4 As shown, the adjustment assembly 8 includes a second slide rail 81 fixedly mounted on the gantry 7, a second slider 82 is slidably provided on the inner side of the slide rail 81, and a second screw rod 83 is rotatably provided on the inner side of the slide rail 81, the second screw rod 83 and the second slide rail 81 are threadedly engaged, and one end of the second screw rod 83 is connected to a second drive motor 84, and a second telescopic rod 9 is connected to the bottom of the second slide rail 81;

[0032] The adjustment of the adjustment component 2 8 is mainly achieved by driving the drive motor 2 84 to drive the screw rod 2 83 to rotate, and through the threaded engagement of the screw rod 2 83 and the slider 2 82, the slider 2 82 is driven to move back and forth in the slide rail 2 81 for adjustment. Through the movement of the slider 2 82, the telescopic rod 2 9 and the polishing component 10 are driven to adjust back and forth, and the position of the workpiece is changed, so that different positions of the workpiece can be adjusted.

[0033] The polishing assembly 10 includes a mounting plate 101 mounted on the telescopic end of the telescopic rod 2 9, a polishing sheet 102 is rotatably mounted on the mounting plate 101, and a servo motor 103 is connected to the upper end of the polishing sheet 102;

[0034] During the polishing process, the extension of the telescopic rod 2 9 drives the polishing assembly 10 to move downward, so that the polishing sheet 102 of the polishing assembly 10 comes into contact with the surface of the workpiece, and the servo motor 2 103 installed on the mounting plate 101 at the upper end of the polishing sheet 102 drives the polishing sheet 102 to rotate, thereby polishing the workpiece.

[0035] Working principle: when grinding and polishing a casting, two surfaces of the workpiece are selected as the clamped surfaces, and the clamping and positioning are performed by the clamping plate 6. When clamping, the workpiece is clamped and positioned by extending the telescopic rod 1 5 to drive the clamping plate 6 on it to approach the clamping plate 6 on the clamping rod 4. After clamping, the polishing assembly 10 is driven downward by extending the telescopic rod 2 9 to move downward and contact the surface of the workpiece for grinding. During the grinding process, the relative position between the polishing assembly 10 and the workpiece can be changed by adjusting the adjustment assembly 1 2 and the adjustment assembly 2 8, so that different positions on the surface of the workpiece can be ground, thereby achieving comprehensive grinding.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
