DETAILED DESCRIPTION
[0018] 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.
[0019] See also Figure 1-3 The present invention provides an implementation scheme: In the modern precision grinding and polishing process, in order to improve the grinding efficiency, a precision grinding and polishing machine is equipped with multiple independent power shafts 3 outside a grinding disc 2 to drive the swing arm 5 to drive the grinding mold to swing and cooperate with the grinding disc 2 to grind. However, in this method, the existing swing arm 5 is mostly installed on the power shaft 3 in a set manner and fixed by bolts. In this method, the working position of the swing arm 5 cannot be switched smoothly during operation, resulting in the swing arm 5 easily interfering with the grinding disc 2 when in use;
[0020] In response to the above problems, the present application discloses a precision grinding and polishing device, the supporting body of the device is a mounting chassis 1, a rotating groove is provided in the center of the mounting chassis 1, and a grinding disc 2 is assembled in the rotating groove. It should be noted that a power mechanism should be provided in the mounting chassis 1, and a control panel 12 is provided on one side of the mounting chassis 1. The operation of the power mechanism is controlled by the control panel 12. The power mechanism and control system of the existing precision grinding and polishing machine are already mature technologies and are not disclosed here. On the one hand, the power mechanism drives the grinding disc 2 to rotate and provide grinding power. On the other hand, the power mechanism drives the three power shafts 3 respectively through linkage, and can independently drive the three power shafts 3 to swing.
[0021] Furthermore, in order to clarify the working state of the swing arm 5, an adjusting shaft 4 is connected to the top end of the power shaft 3, the adjusting shaft 4 is slotted, and then an annular sleeve 6 is extended from the tail end of the swing arm 5 and sleeved on the adjusting shaft 4. The annular sleeve 6 can rotate on the adjusting shaft 4, thereby making the swing arm 5 out of the working range of the grinding disc 2. Specifically, the adjusting shaft 4 is staggered 90° and has a pair of positioning slots 7 distributed up and down. A guide groove 8 is opened on the outer surface of the adjusting shaft 4 along the circumferential direction to connect the pair of positioning slots 7, wherein a pair of positioning slots 7 are located at the bottom and point to the center of the grinding disc 2, while the other positioning slot 7 is staggered 90° and arranged at the top. By adjusting and rotating the swing arm 5 along the direction of the guide slot 8, the swing arm 5 can be switched and locked between the working and idle states.
[0022] Specifically, the inner ring of the annular sleeve 6 extends a limiting short column 9 axially, and the limiting short column 9 is assembled on the guide groove 8. When the swing arm 5 is moved, the limiting short column 9 plays a guiding role. When the limiting short column 9 switches to the position corresponding to the positioning slot 7, the positioning slot 7 is clamped by controlling the limiting clamp 11 on the limiting sleeve 13 to lock the posture of the swing arm 5.
[0023] Furthermore, the three power shafts 3 are arranged in a circular array on one side of the grinding disc 2 to ensure that the swing arms 5 do not interfere with each other during the processing.
[0024] Furthermore, the swing arm 5 has a Y-shaped structure, and a pair of limit sleeves 13 are movably installed on the head ends of both sides of the swing arm 5. During grinding, the mold loaded with the workpiece, such as an optical lens, is placed on the forked position of the swing arm 5, and the pair of limit sleeves 13 are used to form extrusion limits on both sides of the mold.
[0025] According to the instruction manual Figure 1-3 It can be seen that the specific limiting fixture 11 includes a limiting groove 111. The limiting short column 9 axially penetrates to the fixed sleeve 10 to form a limiting groove 111. A limiting rod 112 is inserted into the limiting groove 111. A pair of limiting plates 113 are respectively provided at both ends of the limiting rod 112. A limiting spring 114 is sleeved on the limiting rod 112; one end of the limiting rod 112 penetrates the limiting short column 9 and is inserted into the positioning slot 7, and the other end of the limiting rod 112 penetrates the fixed sleeve 10 and a pull-out plate 115 is provided on the end of the side;
[0026] During the specific implementation process, the limiting rod 112 and the limiting spring 114 are wrapped by the limiting groove 111, and the reverse push of the limiting spring 114 is used to keep one end of the limiting rod 112 in a penetrating posture and insert it into the positioning slot 7, thereby locking the swing arm 5. When it is necessary to contact the working posture of the swing arm 5, the limiting rod 112 is pulled backward by pulling the pull-out plate 115 backward, so that the limiting rod 112 releases the lock on the positioning slot 7, and the swing arm 5 is moved to make the limiting short column 9 slide along the guide groove 8, thereby completing the posture adjustment of the swing arm 5.
[0027] From the above, it can be seen that the precision grinding and polishing machine is improved for the swing arm 5 of the precision grinding and polishing machine, and a split-type connected grooved adjustment shaft 4 is used as a supporting device for fixing the swing arm 5. When in use, a pair of positioning slots 7 designed to be staggered at 90° and a guide groove 8 connecting the two are used to cooperate with the limiting short column 9 of the swing arm 5. A limiting fixture 11 with a telescopic locking function is used to switch the height and direction of the swing arm 5 when working and idle, so as to avoid interference with the grinding disc 2 due to unclear working status of the swing arm 5.
[0028] 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.
