Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a polishing device for producing mechanical support parts. Background Art

[0002] In current life, polishing refers to a process that uses mechanical, chemical, or electrochemical methods to reduce the surface roughness of a workpiece to achieve a bright, smooth surface. It is a finishing process performed using polishing tools and abrasive particles or other polishing media. Polishing does not improve the dimensional or geometric accuracy of a workpiece, but rather aims to achieve a smooth or mirror-like finish. It is also sometimes used to eliminate gloss (matting).

[0003] The existing patent (authorization announcement number: CN219633426U) discloses a polishing device for the production of mechanical support parts, which can drive the support parts to rotate and the polishing disk to move left and right. The support parts cooperate with the polishing disk to perform all-round polishing on the support parts, effectively improving the polishing effect. It can clamp the support parts that need to be polished, effectively preventing the support parts from shifting during the polishing process, and improving the polishing efficiency.

[0004] However, the above technical solution still has certain defects. The debris generated when polishing the object will adhere to the threads of the outer wall of the threaded rod due to centrifugal force, causing it to be blocked or even unable to rotate during rotation, resulting in the first clamping plate being unable to move down to continue clamping the object. It is also necessary to place the object under the top plate and rotate the threaded rod to achieve the clamping effect, but it is unknown whether the object is located in the middle position of the two sets of clamping plates. When the object is rotated to change the polishing surface, the object will come into contact with the base, which may seriously cause permanent damage to the equipment. For this reason, a polishing device for the production of mechanical support parts is proposed. Utility Model Content

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] The following describes an embodiment of the present invention based on its overall structure.

[0025] A polishing device for producing mechanical support parts, such as Figure 1-6As shown, it includes a base 100, a U-frame 110 is fixed on the top of the base 100, and the top of the base 100 is located on the inner side of the U-frame 110 and is movably connected to two groups of driven plates 120, and the inner side wall of each group of driven plates 120 is movably connected to a positioning seat 150, and a servo motor 160 is installed on the outer side wall of the driven plate 120, and the output end of the servo motor 160 passes through the driven plate 120 and is connected to the positioning seat 150, and the interior of the positioning seat 150 is movably connected to a moving plate 151, and both ends of the moving plate 151 extend to the inside of the side wall of the positioning seat 150, and the inner wall of the positioning seat 150 is provided with a spring 152 fixed to the bottom end of the moving plate 151, and the inner wall of the positioning seat 150 is located at the top of the moving plate 151 and is rotatably connected to an eccentric disk 153, and the curved outer wall of the eccentric disk 153 fits with the top of the moving plate 151.

[0026] The positioning seat 150 is composed of two groups of movable seats 154 and a fixed seat 155. An inner U frame 156 extending into the fixed seat 155 is provided on one side of the movable seat 154. A second bidirectional screw rod 157 is rotatably connected to the inner center position of the fixed seat 155. The outer wall of the second bidirectional screw rod 157 is threadedly connected to two groups of driven sleeves 158. The outer walls on both sides of the driven sleeve 158 are rotatably connected to the swing arm 159, and the other end of the swing arm 159 is rotatably connected to the inner U frame 156.

[0027] One end of the second bidirectional screw rod 157 extends to the front surface of the fixing seat 155, and the other end of the second bidirectional screw rod 157 is connected to the inner wall of the fixing seat 155 through a bearing. A matching accommodating groove is provided at the contact position between the fixing seat 155 and the two groups of inner U frames 156.

[0028] The movable plate 151 is a telescopic plate structure, and the telescopic size of the movable plate 151 corresponds to the size of the two sets of movable seats 154.

[0029] The front end of the eccentric disk 153 is rotatably provided with a bolt extending into the interior of the positioning seat 150 , and the inner wall of the positioning seat 150 is provided with a plurality of groups of threaded holes at the contact position of the bolt.

[0030] A driving motor 130 is installed inside the base 100, and the output end of the driving motor 130 is connected to the first bidirectional screw rod 131. The driven plate 120 is threadedly sleeved on the outer wall of the first bidirectional screw rod 131. A polishing device 140 is provided at the inner bottom of the U frame 110, which is located directly above the base 100.

[0031] The rotation of the second bidirectional screw rod 157 can drive the driven sleeve 158 to slide along its surface, so that the two sets of driven sleeves 158 can be relatively close to each other, so that the swing arm 159 gradually rotates to a nearly horizontal state, so that the movable seat 154 can be pushed out to move it away from the two sides of the positioning seat 150, and it can be adjusted to a position that meets the size of the polishing object. At this time, the movable plate 151 will retract and retract with the distance moved by the movable seat 154, and the polishing object is placed above the fixed seat 155. The eccentric disk 153 is adjusted according to the thickness of the polishing object. When the eccentric disk 153 rotates, the bolt at the eccentric position of its surface can move. When it rotates to the threaded hole position at the lowest position, the movable plate 151 can squeeze the spring 152 inside the side wall of the movable seat 154, so that the movable plate 151 presses against the surface of the polishing object, squeezing it and fixing it to ensure its stability.

[0033] When the two sets of driven plates 120 move, they can drive the second protective plate to slide inside the first protective plate, so that it seals the through groove on the top of the base 100 to prevent polishing debris from falling into the interior of the base 100.

[0034] When in use, first adjust the second bidirectional screw 157 according to the size of the polishing object. The second bidirectional screw 157 can be rotated by aligning the hexagonal groove with an external tool. The rotation of the second bidirectional screw 157 can drive the driven sleeve 158 to slide along its surface, so that the two sets of driven sleeves 158 can be relatively close to each other, so that the swing arm 159 gradually rotates to a nearly horizontal state, so that the movable seat 154 can be pushed out to move away from the two sides of the positioning seat 150, and adjusted to a position that meets the size of the polishing object. At this time, the movable plate 151 will retract and retract with the distance moved by the movable seat 154, and the polishing object is placed on the upper side of the fixed seat 155. The eccentric disk 153 is adjusted according to the thickness of the polishing object. When the eccentric disk 153 rotates, the bolt at the eccentric position on its surface can move. When it rotates to the threaded hole position at the lowest position, the movable plate 151 can squeeze the spring 152 inside the side wall of the movable seat 154, so that the movable plate 151 presses against the surface of the polishing object, squeezing it and fixing it to ensure its stability. Starting the drive motor 130 can drive the first bidirectional screw 131 to rotate, so that the driven plate 120 slides along its outer wall, thereby clamping the polishing object. Finally, starting the polishing device 140 can perform the polishing work, which can effectively improve the efficiency of the device and indirectly extend the service life of the device. The parts not mentioned in this device are the same as the existing technology or can be implemented using existing technology.
