Description

Technical Field

[0001] The utility model relates to the technical field of rotating shaft assembly, in particular to a clamping and material-taking mechanism for rotating shaft assembly. Background Art

[0002] A rotating shaft is a mechanical part installed between two solids, allowing the solids to rotate. After the rotating shaft is produced by the corresponding equipment, it needs to be transferred to the position of the part that needs to be transferred for assembly. During the assembly process of the rotating shaft, a material-grabbing mechanism is needed to clamp the rotating shaft and transfer the rotating shaft from one station to another station for assembly, effectively saving manpower.

[0003] Traditional shaft assembly gripping and retrieving mechanisms typically use a single gripper mechanism. After gripping one shaft, the gripper must be transferred to the assembly station and unloaded before the next shaft can be gripped. This gripping method is inefficient. Therefore, we propose a gripper mechanism for shaft assembly that addresses these issues. Utility Model Content

[0006] Preferably, four groups of hinged rods are provided, and the four groups of hinged rods are symmetrically distributed about the central axis of the pushing block.

[0007] Preferably, a plurality of friction particles are provided, and the plurality of friction particles are distributed at equal intervals on the surface of the clamping rubber block.

[0008] Preferably, a groove body is provided at the top of the interior of the horizontal frame, and a threaded rod is installed inside the groove body, and a second servo motor is installed on one side of the threaded rod. A movable seat is movably provided on the outer side wall of the threaded rod, and the top of the movable seat is fixed to the bottom end of the movable frame.

[0009] Preferably, the inner side wall of the movable seat is evenly provided with internal threads, and a threaded connection is formed between the movable seat and the threaded rod.

[0010] Preferably, the cross section of the movable seat is larger than the cross section of the cross frame, and a sliding structure is formed between the movable seat and the cross frame.

[0011] Preferably, a slot is provided on one side of the bottom end of the clamping block, a clamping block is movably provided inside the slot, one side of the clamping block is coated with colloid, and one side of the colloid is fixed to one side of the clamping rubber block.

[0012] Preferably, the cross section of the card block is smaller than the cross section of the card slot, and a card engagement structure is formed between the card block and the card slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the clamping and taking mechanism of the rotating shaft assembly not only ensures that the rotating shaft is clamped up and down without stopping, greatly improving the clamping efficiency, but also facilitates adjustment according to the distance between the rotating shaft placement area and the assembly area, and facilitates the replacement of the clamping rubber block, resulting in better use effect;

[0014] (1) By providing components such as a first servo motor, a fixed seat, a small gear and a large gear, the clamping mechanism is provided with two groups. When the rotating shaft is clamped and moved, different conversions between the two groups of clamping mechanisms continuously grasp and release the rotating shaft, thereby greatly increasing the material picking efficiency of the material picking mechanism, thereby effectively improving the assembly efficiency of the rotating shaft;

[0015] (2) By providing components such as a movable seat, a trough body, and a threaded rod, the distance between the rotating shaft and the assembly area can have different spacings. With the mutual cooperation of the above components, the position of the clamping block can be adjusted when the material picking mechanism is used, thereby facilitating the clamping of rotating shafts with different spacings from the assembly area, and greatly improving the adaptability;

[0016] (3) By providing components such as colloid, card block and card slot, the clamping rubber block at one end of the clamping block greatly increases the friction force of the clamping mechanism on the rotating shaft when the clamping mechanism is in use, so the clamping of the rotating shaft is more stable. When the number of clamping times increases with the increase of use time and the clamping rubber block wears and affects the use, the clamping rubber block can be replaced through the mutual cooperation of the above components, so that the clamping rubber block in the material-taking mechanism can be replaced, and the use effect is better.

[0022] 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.

[0023] Example 1: Please refer to Figure 1-4A clamping and picking mechanism assembled with a rotating shaft includes a fixed base 14, a large gear 16 is movably provided at one end of the fixed base 14, a small gear 15 is meshed with one end of the large gear 16, and a first servo motor 2 is installed on the top of the small gear 15, a rotating base 17 is fixed on the top of the large gear 16, and a mounting frame 1 is installed on the top of the hinged rod 10, a horizontal frame 11 is fixed on both sides of the rotating base 17, a mobile frame 5 is provided on the outer side wall of the horizontal frame 11, a mobile frame 5 is fixed on the bottom end of the mobile frame 5, a telescopic cylinder 8 is installed on the top of the mobile frame 5, a push block 7 is installed on the bottom end of the telescopic cylinder 8, a bracket 9 is fixed on the bottom end of the bracket 9, and both sides of the bottom end of the bracket 9 Each of the clamping blocks 6 is hingedly installed, and a hinged rod 10 is hingedly installed on one side of the inside of the clamping block 6, and one end of the hinged rod 10 is hingedly installed with the pushing block 7. A clamping rubber block 18 is provided at the bottom end of one side of the clamping block 6, and friction particles 20 are provided on the surface of the clamping rubber block 18. There are four groups of hinged rods 10, and the four groups of hinged rods 10 are symmetrically distributed about the central axis of the pushing block 7, which steadily push the clamping block 6 to move and clamp. There are a number of friction particles 20, and the friction particles 20 are evenly spaced on the surface of the clamping rubber block 18. The evenly spaced friction particles 20 greatly increase the friction force of the clamping rubber block 18 on the rotating shaft.

[0024] Specifically, if Figure 1 and Figure 3 As shown, the first servo motor 2 is started to drive the small gear 15 to rotate, and the rotation of the small gear 15 drives the large gear 16 to rotate, so that the large gear 16 drives the horizontal frame 11 on both sides of the upper rotating seat 17 to rotate, so that the pushing block 7 at the bottom end of the horizontal frame 11 rotates to switch, thereby facilitating the clamping of the rotating shafts one by one, reducing the time difference between the conveying of the rotating shafts, and thus improving the efficiency of the rotating shaft assembly.

[0025] Embodiment 2: A groove body 12 is provided at the top of the interior of the horizontal frame 11, and a threaded rod 13 is installed inside the groove body 12, and a second servo motor 4 is installed on one side of the threaded rod 13, and a movable seat 3 is movably provided on the outer side wall of the threaded rod 13, and the top of the movable seat 3 is fixed to the bottom end of the movable frame 5, and the inner side wall of the movable seat 3 is evenly provided with an internal thread, and a threaded connection is formed between the movable seat 3 and the threaded rod 13. The cross section of the movable seat 3 is larger than the cross section of the horizontal frame 11, and a sliding structure is formed between the movable seat 3 and the horizontal frame 11, so that the movable seat 3 drives the clamping block 6 to adjust left and right smoothly;

[0026] Specifically, if Figure 1 and Figure 2 As shown, the second servo motor 4 is started to drive the threaded rod 13 to rotate, and the rotation of the threaded rod 13 drives the movable seat 3 to move on the outer surface of the horizontal frame 11. The moving distance controls the distance between the operating shaft and the assembly area, thereby better performing the transmission of different spacings.

[0027] Example 3: A card slot 22 is provided on one side of the bottom end of the clamping block 6, and a card block 21 is movably provided inside the card slot 22. One side of the card block 21 is coated with a colloid 19, and one side of the colloid 19 is fixed to one side of the clamping rubber block 18. The cross section of the card block 21 is smaller than the cross section of the card slot 22. The card block 21 and the card slot 22 form a card engagement structure, which facilitates the disassembly and replacement of the clamping rubber block 18, making it more convenient to use.

[0028] Specifically, if Figure 4 As shown, when the clamping rubber block 18 is worn out over time, the clamping block 21 is pulled to one side to be disassembled from the inside of the clamping slot 22, and then the clamping rubber block 18 is torn off, and a new clamping rubber block 18 is taken out and coated with colloid 19 on one side of the clamping block 21. The clamping rubber block 18 is adhered to one side of the clamping block 21 through the colloid 19, and then the clamping block 21 is clamped into the inside of the clamping slot 22 to complete the replacement of the clamping rubber block 18.

[0029] Working principle: When the utility model is in use, the clamping mechanism is installed on the corresponding telescopic device through the mounting frame 1, and then the first servo motor 2 is started to drive the small gear 15 to rotate. The rotation of the small gear 15 drives the large gear 16 to rotate, so that the rotating seat 17 above the large gear 16 rotates and drives the clamping block 6 below the side cross frame 11 to rotate and move to the top of the rotating shaft. Then the telescopic device pushes the clamping block 6 to the outer wall of the rotating shaft, and then the telescopic cylinder 8 is started to pull the clamping block 6 inward through the hinged hinge rod 10 to clamp the rotating shaft. After the rotating shaft is clamped, the first servo motor 2 is started again to drive the large gear 16 The reverse rotation allows the clamping block 6 holding the rotating shaft to move to the assembly station, and after the clamping block 6 holding the rotating shaft moves to the assembly station, the clamping block 6 that does not clamp the rotating shaft moves to the top of the rotating shaft, and then the clamping block 6 at this location is operated to clamp the rotating shaft, and the clamping block 6 holding the rotating shaft is operated to release the clamping of the rotating shaft, so that the rotating shaft falls to the assembly position, and then the reverse rotation is allowed to move the clamping block 6 holding the rotating shaft to the assembly position, and the clamping block 6 that releases the rotating shaft is moved to the rotating shaft again for clamping, and the above operation is repeated in a cycle, thereby ensuring the continuous transportation of the rotating shaft and making the rotating shaft assembly efficiency higher.
