[0023] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0024] like Figures 1 to 3 As shown, an automatic loading and unloading mechanism for workpiece grinding processing includes a base 1, a grinding seat 2 is fixedly installed on the back of the base 1, a grinding machine body 3 is provided on the front of the grinding seat 2, a controller 4 is fixedly installed on the left side of the grinding seat 2, a longitudinal slide groove 5 is opened in the middle of the top surface of the base 1, a main mounting column 6 is slidably installed on the inner wall surface of the longitudinal slide groove 5, a support plate 10 is fixedly installed on the top surface of the main mounting column 6, a longitudinal movement mechanism 7 is provided on the surface of the longitudinal slide groove 5 and the main mounting column 6, a lifting mechanism 8 is provided on the surface of the main mounting column 6, a mounting box 9 is provided on the surface of the lifting mechanism 8, and a distance adjustment mechanism 1 is provided on the top surface of the mounting box 9 2. A secondary mounting column 13 is provided on the surface of the distance adjustment mechanism 12. The number of the secondary mounting columns 13 is two and they are symmetrically arranged on the left and right. The opposite surfaces of the two secondary mounting columns 13 are provided with a clamping rotating assembly 14. The clamping rotating assembly 14 includes a rotating shaft 141, an extrusion block 142 and a fourth motor 143. The rotating shaft 141 is rotatably installed on the opposite surfaces of the two secondary mounting columns 13. The opposite surfaces of the base 1 of the two rotating shafts 141 are fixedly installed with extrusion blocks 142. The fourth motor 143 is fixedly installed inside the left secondary mounting column 13, and the output end of the fourth motor 143 is fixedly connected to the left rotating shaft 141.

[0025] Specifically, the object is supported by the support plate 10, and the main mounting column 6 and the support plate 10 are driven to move forward and backward by the longitudinal movement mechanism 7 to realize loading and unloading. When the support plate 10 is located directly below the grinder body 3, the installation box 9, the auxiliary mounting column 13 and the clamping and rotating assembly 14 are driven to rise together by the lifting mechanism 8. When the axis of the clamping and rotating assembly 14 is aligned with the center of the object, the two auxiliary mounting columns 13 are driven to move toward each other under the action of the distance adjustment mechanism 12, and finally the clamping and rotating assembly 14 clamps and fixes the object. The lifting mechanism 8 continues to drive the clamping and rotating assembly 14 to rise, so that the object fixed by the clamping and rotating assembly 14 moves upward and leaves the surface of the support plate 10, so that the surface of the object to be ground is aligned with the grinder body. 3. The object is fitted on the surface. The object is rotated by the clamping rotating assembly 14 to adjust the grinding surface of the object. No manual adjustment is required. It is faster and safer, and the grinding efficiency is effectively improved. When the two auxiliary mounting columns 13 move toward each other, the two extrusion blocks 142 will fit the surface of the object and clamp the object under the action of the rotating shaft 141. When the clamping rotating assembly 14 moves upward under the action of the lifting mechanism 8, the object will leave the surface of the support plate 10, and the rotating shaft 141 and the extrusion block 142 are driven to rotate by the output end of the fourth motor 143, so that the object clamped and fixed by the extrusion block 142 rotates, and the grinding surface of the object is automatically adjusted. There is no need to manually remove and adjust it multiple times, which effectively improves the grinding efficiency.

[0026] like Figures 1 to 3 As shown, the longitudinal movement mechanism 7 includes a mounting groove 701 and a first motor 702. The mounting groove 701 is opened at the lower front part of the main mounting column 6. The first motor 702 is fixedly installed inside the main mounting column 6. The output end of the first motor 702 is fixedly connected with a transmission shaft 703. The transmission shaft 703 is rotatably connected to the top and bottom surfaces of the inner wall of the mounting groove 701. A gear 704 is fixedly mounted on the surface of the transmission shaft 703. A rack 705 is meshed on the surface of the gear 704. The rack 705 is fixedly installed on the right side of the inner wall of the longitudinal slide groove 5.

[0027] Specifically, after the first motor 702 is turned on, it drives the transmission shaft 703 and the gear 704 to rotate. Since the gear 704 is meshed with the surface of the rack 705 and the rack 705 cannot move, the gear 704 will move forward and backward while rotating according to its own direction of rotation, thereby causing the main mounting column 6 to move forward and backward, and causing the pallet 10 fixedly installed on the top surface of the main mounting column 6 and the object supported by the pallet 10 to move forward and backward together, realizing automatic loading and unloading.

[0028] like Figures 1 to 3As shown, the lifting mechanism 8 includes a lifting slot 801 and a second motor 802. The lifting slot 801 is opened on the left and right sides of the main mounting column 6. The second motor 802 is fixedly installed inside the top of the main mounting column 6. The output end of the second motor 802 is fixedly connected to a lifting threaded rod 803. A guide rod 804 is fixedly installed between the top and bottom surfaces of the lifting slot 801. The installation box 9 is slidably installed on the inner wall surface of the lifting slot 801. The installation box 9 is slidably mounted on the surface of the guide rod 804 and is threadedly mounted on the surface of the lifting threaded rod 803.

[0029] Specifically, after the second motor 802 is turned on, it drives the lifting threaded rod 803 to rotate. Since the installation box 9 is threadedly connected to the lifting threaded rod 803, and the installation box 9 is slidingly connected to the guide rod 804 and the surface of the lifting slide groove 801, when the lifting threaded rod 803 rotates, the installation box 9 will move up and down to be lifted and lowered, thereby causing the distance adjustment mechanism 12, the auxiliary installation column 13, the clamping rotation assembly 14 and other structures arranged on the surface of the installation box 9 to be lifted and lowered together.

[0030] like Figures 1 to 3 As shown, the distance adjustment mechanism 12 includes a transverse slide groove 121 and a third motor 122. The transverse slide groove 121 is opened on the top surface of the installation box 9. The third motor 122 is fixedly installed on the right side of the installation box 9. The output end of the third motor 122 is fixedly connected with a transverse threaded rod 123. The auxiliary mounting column 13 is slidably installed on the inner wall surface of the transverse slide groove 121. The auxiliary mounting column 13 is threadedly mounted on the surface of the transverse threaded rod 123. The transverse threaded rod 123 is a double-headed threaded rod.

[0031] Specifically, after the third motor 122 is turned on, its output end drives the transverse threaded rod 123 to rotate. Since the auxiliary mounting column 13 is threadedly mounted on the surface of the transverse threaded rod 123 and is slidably connected to the inner wall surface of the transverse slide groove 121, the two auxiliary mounting columns 13 will rotate synchronously towards or away from each other when the transverse threaded rod 123 rotates, thereby clamping or loosening the object.

[0032] like Figure 1 , Figure 2 As shown, a flexible pad 11 is provided on the top surface of the support plate 10 .

[0033] Specifically, the flexible pad 11 cushions the impact of the object when it is placed on the surface of the support plate 10, thereby preventing the object from being deformed.

[0034] In summary, the utility model supports the object through the support plate 10, drives the main mounting column 6 and the support plate 10 to move forward and backward through the longitudinal movement mechanism 7 to realize loading and unloading, drives the two auxiliary mounting columns 13 to move toward each other through the distance adjustment mechanism 12, and finally clamps and fixes the object through the clamping and rotating assembly 14, drives the clamping and rotating assembly 14 to rise through the lifting mechanism 8, and then lifts the object fixed by the clamping and rotating assembly 14, so as to facilitate the grinding of the object, and drives the object to rotate by the clamping and rotating assembly 14 to realize the adjustment of the grinding surface of the object, without manually adjusting the position of the object, which is faster and safer, and effectively improves the grinding efficiency, and solves the problem that the existing loading and unloading mechanism with both conveying and fixing functions cannot automatically switch the grinding surface of the fixed object, so the position of the object needs to be adjusted manually, resulting in low efficiency and poor safety.
