DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0019] As Figure 1-2 shown, a rotary clamping mechanism for piston polishing according to a preferred embodiment of the present invention includes a bearing seat 1 for connecting the frame. A bearing is provided in the bearing seat 1, a rotating shaft 2 is inserted on the bearing, the rotating shaft 2 is used to connect a rotating mechanism (any existing mechanism capable of driving the rotating shaft to rotate can be used), a rotating base 3 connected to the rotating shaft 2 is provided at the upper end of the bearing seat, a panel 4 is provided on the rotating base 3, and two clamping blocks 5 capable of moving towards or away from each other are provided on the panel 4. The piston is clamped between the two clamping blocks 5.

[0020] The rotary clamping mechanism for piston polishing based on the above technical features is provided with a bearing seat 1 on the frame of the polishing machine. A bearing is arranged inside the bearing seat 1, and a rotating shaft 2 is inserted on the bearing. The rotating shaft 2 is used to connect the rotating mechanism. At the same time, a rotating base 3 connected to the rotating shaft 2 is provided at the upper end of the bearing seat 1. A panel 4 is arranged on the rotating base 3, and two clamping blocks 5 that can move towards or away from each other are arranged on the panel 4. Therefore, when the piston needs to be polished, the piston is first clamped between the two clamping blocks 5, and then the rotating mechanism drives the rotating shaft 2 to drive the rotating base 3 to rotate, so that the piston rotates with the rotating base 3. The brush and the polishing mechanism do not need to move or rotate during the working process, ensuring the polishing effect and further ensuring the product quality.

[0021] In this embodiment, a connecting rod 6 is hinged on the clamping block 5, and the other ends of the two connecting rods 6 are hinged to a transmission shaft 7. The other end of the transmission shaft 7 sequentially passes through the bearing and the rotating shaft 2 and is used to rotatably connect (such as connected by a bearing) a lifting cylinder, that is, the transmission shaft 7 can move relative to the rotating shaft 2. When it is necessary to drive the two clamping blocks 5 to move, the lifting cylinder drives the connecting rod 6, and the connecting rod 6 drives the two clamping blocks 5 to move. When the piston needs to be rotated after clamping, the rotating mechanism drives the rotating shaft 2 to drive the piston to rotate. At this time, under the action of the connecting rod 6, the transmission shaft 7 will also rotate. Since the transmission shaft 7 is rotatably connected to the lifting cylinder, the lifting cylinder will not rotate, and the lifting cylinder can be fixedly arranged on the frame of the polishing machine.

[0022] At the same time, to ensure the moving accuracy of the clamping block 5, two moving components are slidably connected to the panel 4 corresponding to the two clamping blocks 5 one by one. The clamping block 5 is arranged on the moving component, and the connecting rod 6 is hinged to the moving component. Specifically, the moving component includes a moving seat 8 slidably connected to the panel 4. A connecting plate 9 is arranged on the moving seat 8, and the clamping block 5 is arranged on the connecting plate 9. The connecting rod 6 is connected to the moving seat 8, that is, the clamping block 5 slides along the moving seat 8.

[0023] In addition, to further ensure the moving accuracy of the moving seat 8, slide rails 10 are respectively arranged on both sides of the moving seat 8, and sliders 11 are slidably connected to the slide rails 10. The two ends of the connecting plate 9 are respectively connected to the two sliders 11, that is, the moving seat 8 moves under the action of the slide rails 10, ensuring the moving accuracy. The slide rails 10 can be two respectively arranged on both sides of one moving component; or the slide rails 10 on the same side of the two moving components are one, that is, there are a total of two slide rails 10, which are respectively located on both sides of the moving seat 8.

[0024] In this embodiment, the clamping block 5 is provided with a V-shaped groove, and the piston is clamped between the two V-shaped grooves, thereby ensuring the clamping stability of the piston. And when the two clamping blocks 5 are locked, the two V-shaped grooves enclose a locking space, and a support block 12 is provided at the center of the locking space on the panel 4. The support block 12 can be set to be spherical, or the upper end surface is arc-shaped, and the piston is supported on the support block 12 to avoid damage to the surface of the support block 12.

[0025] In addition, the upper surface of the clamping block 5 is covered with a protective plate 13, which can prevent the piston from directly colliding with the clamping block 5 during the clamping of the piston, thereby ensuring the surface quality of the piston.

[0026] In this embodiment, a connecting sleeve 15 is connected between the rotating base 3 and the panel 4. A locking buckle 14 is provided on the outer wall of the connecting sleeve 15, and a locking groove is provided on the locking buckle 14. A locking opening and closing device is provided on the frame of the polishing machine and is matched with the locking groove. When installing or disassembling the piston, first engage the locking opening and closing device with the locking groove to prevent the clamping block from moving, which is convenient for installing or disassembling the piston. When the piston needs to be rotated after installation, separate the locking opening and closing device from the locking groove.

[0027] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
