Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a manipulator for the transformation of a numerical control machine tool. Background Technique

[0002] After the numerical control transformation of an ordinary machine tool, the processing efficiency, automation and intelligence level of the machine tool can be greatly improved. The possibility of the operator contacting dangerous parts is reduced. When transforming the machine tool, a manipulator is needed to carry workpieces and the like.

[0003] For example, a manipulator for the transformation of a numerical control machine tool with the authorization announcement number of "CN221065457U" makes two sliding plates slide inside two card slots, so that the two sliding plates are fixed on both sides above the connecting plate. Two baffle plates can prevent the sliding plates from falling off, so as to fix the connecting plate, thus facilitating the connection of the manipulator for the transformation of the numerical control machine tool. However, when installing the manipulator, it is necessary to fix it through the plate-like structures on both sides and control the movement of the plate-like structures on both sides at the same time, resulting in a long time for alignment and fixation of the device, making the device inconvenient to use. At the same time, when the device is working, the manipulator needs to rotate to carry the workpiece. When the manipulator is damaged due to long-term work, the required maintenance time and cost will increase, resulting in a reduction in the practicability of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of inconvenient use and low practicability of the device, and to provide a manipulator for the transformation of a numerical control machine tool.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design a manipulator for the transformation of a numerical control machine tool, including a base and a rotating shaft. The base is rotationally connected to the rotating shaft through a bearing. The upper end of the rotating shaft is fixedly connected with a turntable. A locking device is arranged on the outer wall of the turntable. A replacement device is arranged at the lower end of the rotating shaft. A supporting plate is fixedly connected to the outer wall of the turntable. The turntable is fitted with a through-hole column through a groove opened on the surface. Through holes are opened on the surface of the through-hole column. A disc is fixedly connected to the upper end of the through-hole column.

[0007] Preferably, the locking device includes a support plate and a plug rod. The outer wall of the plug rod is slidably connected to the turntable. The outer wall of the plug rod is in contact with the through-hole column. One end of the plug rod penetrates through the through-hole column. Symmetrically fixed to the outer wall of the plug rod are sliders, and the outer walls of the sliders are all slidably connected to the turntable. One end of the plug rod penetrates through the turntable, and the outer wall of the plug rod is slidably connected to the support plate. The plug rod is clamped with a first bolt through a groove opened on its outer wall, the first bolt is threadedly connected to the support plate, and a handle is fixedly connected to the upper end of the first bolt.

[0008] Preferably, the lower end of the support plate is fixedly connected to a support plate, and a pull ring is fixedly connected to one end of the plug rod.

[0009] Preferably, a manipulator main body is fixedly connected to the upper end of the disc, and bent plates are symmetrically fixedly connected to the lower end of the base. The bent plates are respectively slidably connected to two second bolts through through-holes opened on their surfaces.

[0010] Preferably, the lower end of the base is fixedly connected to a motor through a motor bracket. The output shaft of the motor is rotatably connected to the base through a bearing, and a first gear is fixedly connected to the outer wall of the output shaft of the motor.

[0011] Preferably, the replacement device includes a top block and a second gear. The rotating shaft of the second gear is clamped with the rotating shaft. The lower end of the second gear abuts against the top block. The top block is rotatably connected to a bent rod through a bearing. The bent rod is slidably connected to a sliding rod. The upper end of the sliding rod is fixedly connected to the base. A through-hole plate is fixedly connected to the upper end of the bent rod. The through-hole plate is slidably connected to a third bolt through a through-hole opened on its surface. The third bolt is threadedly connected to the base.

[0012] The beneficial effect of a manipulator for numerically controlled machine tool transformation proposed by the present utility model is as follows: When transforming a numerically controlled machine tool, it is necessary to carry a workpiece through the manipulator main body. Fix the manipulator main body to the surface of the disc, then insert the through-hole column into the inside of the turntable. At the same time, the operator pushes the plug rod so that one end of the plug rod penetrates through the through-hole column, enabling the through-hole column to be fixed inside the turntable. At the same time, the operator rotates the first bolt through the handle, so that the first bolt can move downward under the action of the support plate, enabling the first bolt to abut against the groove on the surface of the plug rod, fixing the position of the plug rod, and completing the fixation of the manipulator main body. By directly inserting the manipulator into the turntable and then fixing it with the plug rod, quick positioning can be achieved, making the device more convenient to use.

[0013] Through the cooperation of the replacement device and the base, after long-term use, when the rotating part is worn and damaged, the main body of the manipulator can be removed. At the same time, the operator rotates the third bolt so that the third bolt is no longer connected to the base, enabling the bent rod to move downward under the support of the sliding rod. The sliding rod can drive the top block to move downward synchronously, and the top block will no longer be in tight contact with the second gear, allowing the second gear to be disassembled and replaced. This makes the device more convenient for maintenance, eliminating the need to completely rotate through the manipulator. After damage, the repair time can be shortened, making the device more convenient for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Working principle:

[0028] When modifying the CNC machine tool:

[0029] Installation process of the manipulator:

[0030] When modifying the CNC machine tool, it is necessary to carry the workpiece through the manipulator main body 4. Fix the manipulator main body 4 to the surface of the disc 6 (the fixing method can be through bolts). Then insert the through-hole column 5 into the inside of the turntable 7. At the same time, the operator pushes the insertion rod 205 so that one end of the insertion rod 205 penetrates through the through-hole column 5, enabling the through-hole column 5 to be fixed inside the turntable 7. At the same time, the operator rotates the first bolt 202 through the handle 203, causing the first bolt 202 to move downward under the action of the support plate 201, so that the first bolt 202 abuts against the groove on the surface of the insertion rod 205, fixing the position of the insertion rod 205 and completing the fixation of the manipulator main body 4.

[0031] Usage process:

[0032] Control the manipulator main body 4 to carry the workpiece. At the same time, connect the external power supply of the motor 11 and start the output shaft of the motor 11 to rotate, driving the first gear 12 to rotate synchronously. The rotation of the first gear 12 can drive the second gear 902 to rotate synchronously. The second gear 902 can drive the turntable 7 to rotate through the rotating shaft 13, enabling the angle of the manipulator main body 4 to rotate.

[0033] Maintenance process:

[0034] After long-term use, when the rotating part is worn and damaged, the manipulator main body 4 can be removed. At the same time, the operator rotates the third bolt 906 so that the third bolt 906 is no longer connected to the base 1, enabling the bent rod 903 to move downward under the support of the sliding rod 904. The sliding rod 904 can drive the top block 901 to move downward synchronously. The top block 901 will no longer be in tight contact with the second gear 902, allowing the second gear 902 to be disassembled and replaced, making the device more convenient for maintenance. It is not necessary to completely rotate through the manipulator. When damaged, the maintenance time and so on can be shortened, making the device more convenient for maintenance.
