Description

Technical Field

[0001] The utility model relates to the field of crystal processing equipment, in particular to a horizontal lifting mechanism for a crystal grinding machine. Background Art

[0002] During the production process, crystal products need to be ground and polished to make their surfaces translucent. The grinding and polishing process is achieved by repeatedly lifting and lowering the grinding wheel. The stability of the grinding wheel lifting process is directly related to the surface gloss of the finished crystal product. In the existing grinding and polishing machines, two nested sleeves are set under the center of the grinding wheel for guidance. During the lifting process, the surfaces of the two sleeves directly rub against each other, and the friction resistance during the lifting process is relatively large. The fitting gap between the two sleeves will gradually increase with the accumulation of usage time, causing the grinding wheel to deviate during the lifting process, affecting the surface effect of the crystal product.

[0021] 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.

[0022] The utility model discloses a horizontal lifting mechanism for a crystal grinding machine, comprising a fixed frame 1, a movable frame 2 and a driving assembly 3. Figure 1-3 The fixed frame 1 includes a fixed panel 11 and at least two fixed plates 12. The fixed panel 11 is fixedly connected to the frame of the crystal grinding machine. A connecting hole 111 is provided in the fixed panel 11, and the fixed plate 12 is fixed in the connecting hole 111; a movable frame 2 is provided in the connecting hole 111, and the movable frame 2 can move up and down in the connecting hole 111. A plurality of linear guide rails 21 are provided between the movable frame 2 and the fixed plate 12. The linear guide rails 21 are used for guiding and connecting the movable frame 2 during lifting and sliding. With its unique precision connectivity and smoothness, it improves the accuracy of the movable frame 2 during the lifting process. The top of the movable frame 2 is rotatably connected to the grinding disc 22; a driving assembly 3 includes a driving motor 31 fixed to the bottom of the fixed frame 1, and a driving screw 32 is provided on the driving motor 31. A screw nut 33 is sleeved on the driving screw 32, and the screw nut 33 is fixedly connected to the movable frame 2. When the equipment is in operation, the lifting and lowering of the movable frame 2 can be controlled by the driving motor 31.

[0023] Since the gaps between the internal components of the linear guide 21 are not adjustable, the main body shapes of the frames in traditional lifting mechanisms are fixed. However, actual processing cannot perfectly ensure that the spacing between the frames can accommodate the linear guide. As a result, after the linear guide is installed, the slider and the guide may not fit together due to excessive gaps, or the slider and the guide may be stuck and unable to slide due to excessive gaps. In this mechanism, the fixed frame 1 is composed of a fixed panel 11 and a fixed plate 12 that are fixed by bolts. During installation, the linear guide 21 can be first installed on the movable frame, and then the spacing between the fixed panel 11 and the fixed plate 12 can be adjusted to meet the installation requirements of the linear guide, thereby ensuring that the linear guide 21 can be installed and used normally.

[0024] See Figure 3There are two fixing plates 12, and the two fixing plates 12 are arranged on opposite sides so that the force points on the movable frame 2 are located on two symmetrical sides, avoiding the linear guide rail 21 from being affected by shear force, thereby extending the service life. A connecting boss 121 is provided on the fixing plate 12, and the connecting boss 121 is preferably located above the fixed panel 11. The connecting boss 121 is fixedly connected to the fixed panel 11 by bolts.

[0025] See Figure 1 A connecting plate 13 is provided at the bottom end of the fixing plate 12, and the driving motor 31 is fixed on the connecting plate 13. The output shaft of the driving motor 31 passes through the connecting plate 13 upward. The driving motor 31 is preferably located on one side of the connecting plate 13 so as to increase the overlap of the internal structure of the equipment in the horizontal direction, so as to reduce the vertical height space occupied by the entire equipment.

[0026] See Figure 1 The movable frame 2 is provided with a plurality of bearings, on which a rotating shaft 23 is provided, and the grinding disc 22 is fixed to the top of the rotating shaft. The rotation of the rotating shaft 23 is realized by an external motor, and the principle of the rotating part is the same as that of the prior art.

[0027] See Figure 3 A connecting block 34 is fixed on the screw nut 33 , and the connecting block 34 and the screw nut 33 are fixed by bolts. The connecting block 34 and the moving frame 2 are fixedly connected by bolts, thereby fixing the screw nut 33 and the moving frame 2 .

[0028] See Figure 3 The fixing plate 12 is provided with a clearance groove 122, and the connecting block 34 slides in the clearance groove 122. The setting of the clearance groove 122 makes the internal structure of the device more compact, thereby improving the internal space utilization of the device.

[0029] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
