Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical automation technology, and specifically relates to a mechanical automated clamping device. Background Technology
[0002] In modern industrial production, automated mechanical gripping devices are widely used in material handling, assembly, and other production processes. Traditional gripping devices typically only perform gripping actions in a single direction, or their movement patterns are relatively fixed, making it difficult to meet the diverse needs for gripping direction, angle, and position in complex production scenarios. For example, in some tasks requiring multi-angle gripping and assembly of irregularly shaped parts, existing gripping devices, lacking flexible movement modes, cannot accurately complete the operation, resulting in low production efficiency and difficulty in guaranteeing product quality. Therefore, designing an automated mechanical gripping device that enables the gripping mechanism to rotate and revolve to meet different usage requirements is of significant practical importance. Utility Model Content
[0003] To address the problems mentioned in the background section, this invention provides a mechanically automated gripping device. By incorporating a gripper revolution mechanism and a gripper rotation mechanism, the gripping mechanism can rotate and revolve, thereby meeting different usage requirements and improving the flexibility and applicability of the gripping device.
[0004] An automated mechanical gripping device includes a mounting bracket, on which a gripping mechanism is mounted via a gripper revolution mechanism and a gripper rotation mechanism. The gripper revolution mechanism includes a geared motor fixed to the mounting bracket and a driven gear movably mounted on the mounting bracket via bearings. A driving gear is fixed to the output shaft of the geared motor, and a support arm is fixed to the top of the driven gear. The gripper rotation mechanism includes a servo motor mounted at one end of the support arm and a rotating shaft movably mounted at the other end of the support arm. A crank is fixed to the output shaft of the servo motor, a second crank is fixed to the top of the rotating shaft, and the gripping mechanism is mounted at the bottom of the rotating shaft. A connecting rod is movably arranged between the first crank and the second crank. Furthermore, the mounting bracket is provided with a motor mounting base for supporting the geared motor. The motor mounting base is fixedly connected to the mounting bracket by bolts, and the motor mounting base is provided with heat dissipation holes to ensure heat dissipation during the operation of the geared motor. Furthermore, the driving gear and the driven gear mesh with each other, and the diameter of the driving gear is smaller than the diameter of the driven gear. Furthermore, the support arm is a hollow tubular structure with internal wiring channels for passing through the servo motor power lines and control lines. Furthermore, the output shaft of the servo motor is connected to the crank one by a key. The key is a flat key, and locating pins are provided on both sides of the key to prevent the crank one from rotating circumferentially and moving axially on the output shaft of the servo motor. Furthermore, the shaft and the support arm are connected by a deep groove ball bearing. The inner ring of the deep groove ball bearing is interference-fitted with the shaft, and the outer ring is transition-fitted with the bearing mounting hole on the support arm. Dust covers are provided at both ends of the bearing to prevent dust and impurities from entering the bearing. Furthermore, the two ends of the connecting rod are connected to crank one and crank two respectively through spherical bearings. The spherical bearings can achieve multi-directional rotation, ensuring the flexibility and stability of the connecting rod during transmission. Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a chuck revolution mechanism, in which a reduction motor drives the drive gear to rotate. The drive gear meshes with the driven gear, causing the driven gear to drive the support arm to revolve, thereby realizing the revolution motion of the gripping mechanism. This can change the overall position of the gripping mechanism and meet the material handling needs between different workstations. The chuck rotation mechanism uses a servo motor to drive crank one to rotate, and transmits the motion to crank two through a connecting rod, thereby causing the shaft to drive the clamping mechanism to rotate. The clamping angle of the clamping mechanism can be adjusted, making it suitable for clamping and assembling parts at different angles. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0007] like Figure 1-4 As shown; A mechanical automated gripping device.
[0008] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "In modern industrial production, automated mechanical gripping devices are widely used in material handling, assembly, and other production processes. Traditional gripping devices typically can only perform gripping actions in a single direction, or their movement patterns are relatively fixed, making it difficult to meet the diverse needs for gripping direction, angle, and position in complex production scenarios. For example, in some tasks requiring multi-angle gripping and assembly of irregularly shaped parts, existing gripping devices, lacking flexible movement patterns, cannot accurately complete operations, resulting in low production efficiency and difficulty in guaranteeing product quality." In practical terms, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, an automated mechanical gripping device is provided.
[0009] like Figure 1-4 As shown in the figure; Based on the above, the device includes a mounting bracket 1, on which a clamping mechanism 4 is provided via a clamping revolution mechanism 2 and a clamping rotation mechanism 3. The clamping revolution mechanism 2 includes a reduction motor 21 fixed on the mounting bracket 1 and a driven gear 22 movably mounted on the mounting bracket 1 via bearings. The output shaft of the reduction motor 21 is fixed with a driving gear 23, and a support arm 24 is fixedly mounted on the top of the driven gear 22. The clamping rotation mechanism 3 includes a servo motor 31 mounted on one end of the support arm 24 and a rotating shaft 32 movably mounted on the other end of the support arm 24. The output shaft of the servo motor 31 is fixed with a crank 33, and a crank 34 is fixed to the top of the rotating shaft 32. The clamping mechanism 4 is mounted on the bottom of the rotating shaft 32, and a connecting rod 35 is movably arranged between the crank 33 and the crank 34.
[0010] The mounting bracket 1 is provided with a motor mounting base for supporting the geared motor 21. The motor mounting base is fixedly connected to the mounting bracket 1 by bolts, and the motor mounting base is provided with heat dissipation holes to ensure the heat dissipation of the geared motor 21 during operation.
[0011] The driving gear 23 meshes with the driven gear 22, and the diameter of the driving gear 23 is smaller than the diameter of the driven gear 22.
[0012] The support arm 24 is a hollow tubular structure with internal wiring channels for the power and control lines of the servo motor 31.
[0013] The output shaft of the servo motor 31 is connected to the crank 33 by a key. The key is a flat key, and locating pins are provided on both sides of the key to prevent the crank 33 from rotating circumferentially and moving axially on the output shaft of the servo motor 31.
[0014] The shaft 32 and the support arm 24 are connected by a deep groove ball bearing. The inner ring of the deep groove ball bearing is interference-fitted with the shaft 32, and the outer ring is transition-fitted with the bearing mounting hole on the support arm 24. Dust covers are provided at both ends of the bearing to prevent dust and impurities from entering the bearing.
[0015] The two ends of the connecting rod 35 are connected to crank 33 and crank 34 respectively through spherical bearings. The spherical bearings can achieve multi-directional rotation, ensuring the flexibility and stability of the connecting rod 35 during transmission.
[0016] In practical applications, the mounting bracket is first fixed in a suitable working position. The geared motor of the chuck rotation mechanism is started. The output shaft of the geared motor drives the driving gear to rotate. Since the driving gear and the driven gear mesh with each other, and the diameter of the driving gear is smaller than that of the driven gear, the driven gear rotates under the drive of the driving gear. This causes the support arm fixed on the top of the driven gear to rotate, thereby realizing the horizontal position adjustment of the clamping mechanism. When the gripping angle of the clamping mechanism needs to be adjusted, the servo motor of the chuck rotation mechanism is activated. The output shaft of the servo motor drives crank one to rotate, and the rotation is transmitted to crank two through the connecting rod. Crank two drives the rotating shaft to rotate, thereby causing the clamping mechanism mounted at the bottom of the rotating shaft to rotate. By controlling the rotation angle and speed of the servo motor, the gripping angle of the clamping mechanism can be precisely adjusted to adapt to different working requirements. Throughout the entire operation, the heat dissipation holes on the motor mounting base effectively dissipate the heat generated by the geared motor, ensuring its normal operation. The wiring channel inside the support arm facilitates the arrangement of the servo motor's power and control lines. The keyed connection and locating pin between the servo motor output shaft and crank arm ensure the stability of power transmission. The deep groove ball bearing and dust cover between the shaft and the support arm ensure the shaft's flexible rotation and long-term stable operation. The spherical bearings at both ends of the connecting rod allow the connecting rod to rotate flexibly during transmission, ensuring the smoothness and reliability of the clamping mechanism's rotational motion.
[0017] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
