Description

Technical Field

[0001] This utility model relates to the field of weight calibration, and in particular to an automatic loading device for weight calibration. Background Technology

[0002] Weight calibration refers to the process of accurately measuring, comparing, and correcting the actual mass value of weights through specific technical means and standard procedures to determine the consistency between their mass and nominal value and to ensure that they meet the requirements of national or international metrological standards. Its core purpose is to eliminate mass deviations caused by factors such as manufacturing errors, wear and tear, and environmental influences, thereby ensuring the accuracy and reliability of measurement results.

[0003] Automatic loading devices are used in weight calibration operations. In a Chinese patent entitled "An Automatic Loading Device for Electronic Scale Calibration" with publication number CN216309201U, a robotic arm clamps and lifts the protruding end of the weight box cover, opening the cover from above the weight box. The weights are then picked up, rotated, and placed on the weighing pan of the electronic scale, automatically loading the electronic scale for calibration. However, in the aforementioned application, the electronic scale and the weight box are on the same straight line during loading. When the position of the electronic scale changes, the entire loading device needs to be moved, resulting in low flexibility of the loading device during use and affecting the efficiency of the entire calibration process.

[0061] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0062] Figures 1 to 6 The diagram shown is a structural schematic of an embodiment of the automatic loading device for weight calibration of this utility model. The automatic loading device for weight calibration includes a movable base 1, and the storage box 4 is provided with a detachable top cover.

[0063] Storage platform 2 and fixed column 3, the bottom of the storage platform 2 is connected to a plurality of fixed columns 3 arranged in a ring array, and the bottom end of the fixed column 3 is connected to the top of the movable base 1;

[0064] Storage box 4, which is placed on top of storage platform 2, contains multiple weight bodies 5;

[0065] Mounting ring platform 6 is provided on the outside of the storage platform 2. The mounting ring platform 6 is connected to the top of the movable base 1 through a rotating component 7.

[0066] The gripping component 8 is disposed above the rotating component 7, and the gripping component 8 is connected to the mounting ring platform 6 via a control mechanism.

[0067] In this technical solution, the position of the gripping component 8 is adjusted by the rotating component 7 and other structures, so that the gripping component 8 can place the weight body 5 on the measuring equipment at different positions, avoiding frequent movement of the entire device due to different positions of the measuring equipment, improving the efficiency of weight calibration, and increasing the flexibility of the automatic loading device when in use.

[0068] The rotating component 7 includes a rotation drive source 71, the output end of which is connected to a drive gear 72, the drive gear 72 is meshed with a transmission gear 73 on its side, and the transmission gear 73 is meshed with a driven gear 74 on its side.

[0069] The driven gear 74 is meshed with the inner side of the ring gear 75, the outer side of the ring gear 75 is connected to the inner side of the connecting ring 76, and the connecting ring 76 is connected to the bottom of the mounting ring platform 6.

[0070] In this technical solution, the position of the gripping component 8 is adjusted by rotating component 7.

[0071] Both the transmission gear 73 and the driven gear 74 are connected to a rotating column 77 at their bottom, and the bottom end of the rotating column 77 is rotatably connected to the top of the movable base 1.

[0072] In this technical solution, the transmission gear 73 and the driven gear 74 are supported by the rotating column 77.

[0073] In use, the rotary drive source 71 drives the drive gear 72 to rotate, which in turn drives the transmission gear 73 to rotate. This drives the driven gear 74 to rotate, which in turn drives the ring gear 75 to rotate, which in turn drives the connecting ring 76 to rotate. The rotation of the connecting ring 76 drives the mounting ring platform 6 and the gripping assembly 8 to rotate, thereby adjusting the position of the gripping assembly 8.

[0074] The connecting ring 76 is movably connected to the movable base 1 via the auxiliary component 9. The auxiliary component 9 includes a fixed track ring 91, which is connected to the top of the movable base 1. The surface of the fixed track ring 91 is slidably connected to the inner side of the connecting ring 76.

[0075] The fixed track ring 91 is rotatably connected to a plurality of two sets of support components near the bottom surface of the connecting ring 76. Each set of support components consists of a plurality of support balls 92 arranged in a ring array, and the support balls 92 are in contact with the bottom surface of the connecting ring 76.

[0076] In this technical solution, the auxiliary component 9 makes the rotation of the mounting ring platform 6 smoother.

[0077] The inner side of the mounting ring 6 is connected to a rotating track ring 10, and the side of the storage platform 2 is provided with a track groove. The rotating track ring 10 is slidably connected to the side of the storage platform 2 through the track groove.

[0078] In this technical solution, the rotation trajectory of the mounting ring 6 is limited by rotating the track ring 10.

[0079] When the connecting ring 76 rotates, it rotates around the fixed track ring 91. When the mounting ring platform 6 rotates, it drives the rotating track ring 10 to rotate along the side of the storage platform 2. The fixed track ring 91, the supporting ball 92, and the rotating track ring 10 limit the rotation trajectory of the connecting ring 76 and the mounting ring platform 6, making the connecting ring 76 and the mounting ring platform 6 more stable and smooth when rotating.

[0080] The gripping component 8 includes a mounting top plate 81, the bottom of which is connected to the control mechanism, and a lifting device 82 is connected to the bottom of the mounting top plate 81. An automatic gripper 83 is connected to the bottom of the lifting device 82.

[0081] In this technical solution, the gripping component 8 is used to perform gripping and releasing operations.

[0082] In use, the lifting device 82 drives the automatic gripper 83 to move, and the height of the automatic gripper 83 is adjusted so that the automatic gripper 83 is close to the weight body 5 in the storage box 4. Then, the automatic gripper 83 is used to grip the weight body 5. Then, the lifting device 82, the leveling component 13 and the height adjustment component 11 are used to place the gripped weight body 5 on the measuring equipment for calibration.

[0083] The control mechanism includes a height adjustment component 11 and a lifting platform 12. The height adjustment component 11 is connected to the top of the mounting ring platform 6. The upper end of the height adjustment component 11 is connected to the bottom of the lifting platform 12. The top of the lifting platform 12 is connected to a leveling component 13. The output end of the leveling component 13 is connected to the bottom of the mounting top plate 81.

[0084] In this technical solution, the position of the gripping component 8 is adjusted by a control mechanism.

[0085] The height adjustment component 11 includes a mounting frame 111, the bottom of which is connected to the top of the mounting ring platform 6. Multiple cross-rotating brackets 112 are provided above the mounting frame 111 and between the lifting platform 12. Both ends of the cross-rotating brackets 112 are rotatably connected to rotating connecting seats 113.

[0086] The rotating connecting seat 113 located at the top is connected to the bottom of the driven plate 114. The driven plate 114 is slidably connected to the surface of the limiting rail 115. The two ends of the limiting rail 115 are respectively connected to the inner side wall of the cross rotating frame 112.

[0087] The rotating connecting seat 113 located below is connected to the top of the active plate 116. The active plate 116 is threadedly connected to the surface of the bidirectional threaded shaft 117. One end of the bidirectional threaded shaft 117 is connected to the output end of the height adjustment power source 118. The height adjustment power source 118 is connected to the outside of the mounting frame 111.

[0088] In this technical solution, the height of the gripping component 8 and other structures is adjusted by adjusting the height of the height adjustment component 11.

[0089] The surface of the bidirectional threaded shaft 117 is threaded with two symmetrically distributed active plates 116;

[0090] The inner wall of the mounting frame 111 is connected to a plurality of positioning rails 119, and the surface of the positioning rails 119 is slidably connected to the active plate 116.

[0091] In this technical solution, the positioning track 119 is used to limit the movement trajectory of the active plate 116.

[0092] In use, the height-adjusting power source 118 drives the bidirectional threaded shaft 117 to rotate, thereby driving the active plates 116 on both sides to move towards or away from each other along the positioning track 119. At this time, with the cooperation of the rotating connecting seat 113, the cross rotating frame 112 is rotated, thereby driving the driven plate 114 to move along the limiting track 115.

[0093] When the cross-rotor 112 rotates, its height changes, which causes the limit track 115 and the lifting platform 12 to move in the same direction, and in turn causes the leveling component 13 and the gripping component 8 to move in the same direction, thereby adjusting the height of the gripping component 8 and other structures.

[0094] The leveling component 13 includes a support frame 131 and a rotating central shaft 132. The bottom of the support frame 131 is connected to the top of the lifting platform 12. The bottom end of the rotating central shaft 132 is rotatably connected to the bottom of the inner cavity of the support frame 131. The top end of the rotating central shaft 132 is rotatably connected to the top surface of the support frame 131. The top end of the rotating central shaft 132 is connected to the bottom of the mounting top plate 81.

[0095] The bottom of the inner cavity of the support frame 131 is connected to a leveling power source 133. The output end of the leveling power source 133 is connected to a first gear 134. The side of the first gear 134 is meshed with a second gear 135. The second gear 135 is connected to the surface of the rotating central shaft 132.

[0096] In this technical solution, the gripping component 8 is rotated horizontally by the leveling component 13.

[0097] The support frame 131 is connected to a plurality of anti-deviation rails 136 on its side. The mounting top plate 81 has an L-shaped cross-section and an anti-deviation groove is provided on the inner side of the mounting top plate 81. The anti-deviation rails 136 are slidably connected to the mounting top plate 81 through the anti-deviation groove.

[0098] In use, the leveling power source 133 drives the first gear 134 to rotate, which in turn drives the second gear 135 to rotate. When the second gear 135 rotates, it drives the rotating central shaft 132 to rotate, which in turn drives the mounting top plate 81 to rotate. This, in turn, drives the lifting device 82 and the automatic gripper 83 to rotate, thereby adjusting the angle of the gripping component 8.

[0099] The rotary drive source 71, the height adjustment power source 118, and the horizontal adjustment power source 133 are motor sets or other devices that output rotational kinetic energy.

[0100] The lifting device 82 is an electric push rod, a lifting cylinder, or other equipment with autonomous extension and retraction functions.
