[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Example 1

[0032] The embodiment of the present application discloses a clamping mechanism for an edge grinding machine.

[0033] Reference Figure 1 The clamping mechanism of the edge grinding machine includes a supporting platform 1, a bearing seat 2, a base 3, a clamping assembly 4 and a driving assembly 5.

[0034] Reference Figure 1 The bearing seat 2 is installed on the support platform 1, and the bearing seat 2 is used to place the objects to be polished. Two bases 3 are slidably installed on the support platform 1. The two bases 3 are respectively located on both sides of the bearing seat 2 along the length direction of the support platform 1, and the sliding directions of the two bases 3 are opposite.

[0035] Reference Figure 1 , Figure 2 The driving assembly 5 is installed on the support platform 1. The driving assembly 5 is used to drive the base 3 to slide on the support platform 1. The driving assembly 5 includes a motor 51 and a screw rod 52. The motor 51 is installed on both sides of the support platform 1. In this embodiment, the motor 51 is a servo motor 51. The screw rod 52 is coaxially installed on the output shaft of the motor 51 along the sliding direction of the base 3, and the screw rod 52 is threadedly penetrated into the base 3.

[0036] Start the motor 51, and the output shaft of the motor 51 rotates forward or reversely, which can cause the screw rod 52 to rotate forward or reversely. During the rotation process, the screw rod 52 can drive the base 3 to slide on the support platform 1 in a direction close to the bearing seat 2 or away from the bearing seat 2, so as to adjust the position of the base 3 conveniently and quickly.

[0037] Reference Figure 1 , Figure 2 The clamping assembly 4 is installed on the base 3, and the clamping assembly 4 is used to press the object on the bearing seat 2. The clamping assembly 4 includes a lifting seat 41, a clamping device 42 and a lifting member 43. The lifting seat 41 is slidably installed on the base 3 along the vertical direction, and the clamping device 42 is installed on the lifting seat 41. The clamping device 42 is used to press onto the object. In this embodiment, the clamping device 42 is a U-shaped ring, and the clamping device 42 is installed on the lifting seat 41 by bolts. The staff can easily replace the clamping device 42 by tightening the bolts; the lifting member 43 is installed on the base 3, and the lifting member 43 is used to drive the lifting seat 41 to slide. The lifting member 43 includes a cylinder 431, and the cylinder 431 is installed on the base 3 along the vertical direction. The piston rod of the cylinder 431 is connected to the lifting seat 41.

[0038] When the base 3 is close to the supporting seat 2 and the clamp 42 is located above the supporting seat 2, the piston rod of the cylinder 431 retracts, which can drive the lifting seat 41 to slide up and down on the base 3. The lifting seat 41 can drive the clamp 42 to press the objects on the supporting seat 2, thereby conveniently and quickly pressing and positioning the objects on the supporting seat 2. The cylinder 431 is used to drive the pressing plate to move up and down. By setting different strokes of the cylinder 431, the pressing plate can press objects of different thicknesses on the supporting seat 2, thereby improving the applicability of pressing and positioning objects of different thicknesses on the supporting seat 2.

[0039] Reference Figure 1 The clamps 42 on the two bases 3 are staggered. In this embodiment, one of the clamps 42 has a larger opening, and the other clamp 42 has a smaller opening. The clamp 42 with a larger opening can accommodate the clamp 42 with a smaller opening.

[0040] When one of the clamps 42 is pressed on the object, the other base 3 is close to the base 3, so that the other clamp 42 is located above the object, and then the cylinder 431 drives the other clamp 42 to descend and press on the object, so that the two clamps 42 can press on the object at the same time. When the clamp 42 is replaced to press the object, the object can always be pressed tightly on the support seat 2, which improves the stability of the object on the support seat 2 when the two clamps 42 switch to press the object, thereby ensuring the accuracy of subsequent edge grinding of the object.

[0041] The implementation principle of Example 1 of the present application is as follows: the staff first places the object to be polished on the supporting seat 2, and then starts the motor 51 on one side of the supporting seat 2. The motor 51 drives the screw rod 52 to rotate and tends to move the base 3 on one side of the supporting seat 2 toward the supporting seat 2. The base 3 drives the pressure plate to move directly above the object, and then the piston rod of the cylinder 431 on the base 3 retracts, so that the pressure plate is pressed onto the object, and the object can be pressed and positioned on the supporting seat 2, and then the side of the object can be polished. After the polishing is completed, the motor 51 on the other side of the supporting seat 2 is started, so that the base 3 on the other side of the supporting seat 2 moves toward Move in the direction close to the supporting seat 2, the base 3 drives the other pressure plate to move to just above the object, and then the piston rod of the cylinder 431 on the base 3 retracts, so that the other pressure plate is pressed onto the object, and the pressure plate that was first pressed on the object releases the pressure on the object under the action of the extension of the piston rod of the cylinder 431, and then the base 3 that was first close to the supporting seat 2 is driven by the motor 51 to drive the pressure plate away from the supporting seat 2, at this time, the side of the pressure plate that was first pressed on the object can be polished, and the circumferential side grinding of the object can be completed without changing the position angle of the object, thereby effectively improving the grinding efficiency of the edge grinding machine for the object.

[0042] Example 2

[0043] Reference Figure 3 The difference between this embodiment and embodiment 1 is that: a positioning assembly 6 is installed on the bearing seat 2, and the positioning assembly 6 is used to position the object. The positioning assembly 6 includes a slider 61, a baffle 62 and an electric push rod 63. The slider 61 is slidably installed on the outer wall of the bearing seat 2 along the vertical direction. Two baffles 62 are slidably installed on the slider 61 along the horizontal direction. The two baffles 62 are respectively located on the adjacent two sides of the bearing seat 2. The electric push rod 63 is vertically installed on the bearing seat 2, and the piston rod of the electric push rod 63 is connected to the slider 61; a control member 7 is installed on the slider 61, and the control member 7 is used to drive the baffle 62 to slide. The control member 7 includes a screw 71, which is rotatably installed on the slider 61, and the screw 71 is threadedly connected to the baffle 62.

[0044] The implementation principle of Example 2 of the present application is as follows: before placing the object on the supporting seat 2, the staff first rotates the screw 71 according to the shape and size of the object, so that the baffle 62 slides horizontally on the slider 61, and adjusts the distance between the baffle 62 and the supporting seat 2, so that the two baffles 62 can be suitable for objects of different shapes and sizes, thereby improving the applicability of the baffle 62 for positioning objects of different shapes and sizes; after adjusting the baffle 62, the staff drives the piston rod of the electric push rod 63 to extend, so that the baffle 62 moves to the top of the supporting seat 2, and the two baffles 62 are respectively located on the adjacent two sides of the supporting seat 2. At this time, the staff can place the object on the supporting seat 2, so that the two sides of the object are respectively abutted against the two baffles 62, and the object can be positioned and placed on the supporting seat 2 according to the set position, thereby improving the convenience of the staff to accurately place the object according to the set position.
