Description

Technical Field

[0001] This utility model relates to the field of anti-tipping material handling mechanisms, and in particular to an adaptive clamping arm anti-tipping material handling mechanism. Background Technology

[0002] In modern automated production systems, the efficient grasping and handling of materials is a key link in the intelligentization of production lines, and its technological iterations have always revolved around the two core requirements of "flexible adaptation" and "stability assurance".

[0003] Existing mechanisms mostly rely on rigid clamping with a single clamping arm or symmetrical clamping arms. When the center of gravity of the workpiece shifts, the lateral torque can easily cause the workpiece to tip over during the material handling process (the tilt angle can reach more than 5°), resulting in material loss or equipment failure. To address this issue, an adaptive clamping arm anti-tipping material handling mechanism is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adaptive clamping arm anti-tipping material handling mechanism, which aims to improve the problem in the prior art that "traditional rigid clamping arms cannot adaptively compensate for the workpiece's center of gravity shift, causing the workpiece to easily tip over due to lateral torque during the material handling process".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive clamping arm anti-tipping material handling mechanism, including a mounting base, a driving mechanism fixedly connected to the upper right side of the mounting base, a lead screw rotatably connected to the inner wall of the mounting base, a lower part of the driving mechanism fixedly connected to the outside of the lead screw, a sleeve threadedly connected to the outside of the lead screw, a connecting rod fixedly connected to the lower part of the sleeve, a clamping rod a fixedly connected to the front and rear sides of the connecting rod, and a rotating component provided on the upper part of the connecting rod;

[0006] The rotating assembly includes a support member that rotates through the inner wall of the connecting rod. A bottom cover is fixedly installed on the lower part of the support member by bolts. Two sets of operating members are slidably connected to the inner wall of the support member. A spring is provided on the opposite side of the two sets of operating members. A plug is fixedly connected to the outer side of the operating member. Multiple sets of slots are opened on the upper part of the connecting rod. The operating members are engaged in the inner wall of the slots. A moving member is slidably connected to the inner wall of the support member. A clamping rod b is fixedly connected to the lower part of the moving member.

[0007] As a further description of the above technical solution:

[0008] An adjustment assembly is provided on the upper part of the support member. The adjustment assembly includes a set screw, which is threaded to the inner wall of the support member. A limit hole is opened on the outer side of the moving member, and the lower part of the set screw passes through the limit hole.

[0009] As a further description of the above technical solution:

[0010] The limiting holes are provided in multiple sets, and the multiple sets of limiting holes are evenly provided through the outside of the moving part.

[0011] As a further description of the above technical solution:

[0012] The operating component is configured in an L-shape.

[0013] As a further description of the above technical solution:

[0014] An arc-shaped baffle is provided on the outside of the operating component.

[0015] As a further description of the above technical solution:

[0016] The connector is configured as an isosceles trapezoid.

[0017] As a further description of the above technical solution:

[0018] A twist cap is provided on the upper part of the set screw.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the operating component is designed in an L-shape, and the outer arc baffle is easy to press with fingers. Only one hand is needed to squeeze the spring to disengage the plug-in component from the slot, thereby adjusting the angle of the support component. This allows clamping rod a and clamping rod b to form a clamping structure, ensuring that the workpiece is prevented from tipping over due to instability during the material handling process.

[0021] 2. In this utility model, by adjusting the engagement of the set screw and multiple sets of limiting holes in the adjustment assembly, the length of the moving part can be adjusted as needed, so that the clamping range formed by clamping rod b and clamping rod a can be adapted to workpieces of different thicknesses, and can be compatible with multiple specifications of materials without changing the hardware.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Reference Figures 1-3 This utility model provides an embodiment of an adaptive clamping arm anti-tipping material handling mechanism, including a mounting base 1, which serves as the basic support component of the entire mechanism. It is used to install the drive mechanism 2, lead screw 3, and other components, ensuring stable installation and operation of the entire mechanism. The drive mechanism 2, consisting of a servo motor, two sets of transmission wheels, and a synchronous belt, is fixedly connected to the upper right side of the mounting base 1. The transmission wheels are fixedly connected to the outside of the lead screw 3, providing power for its rotation. The lead screw 3, a bidirectional lead screw, is rotatably connected to the inner wall of the mounting base 1 and cooperates with a sleeve 4 to convert the rotational motion of the drive mechanism 2 into that of the sleeve. The linear motion of 4 is driven by a drive mechanism 2 which is fixedly connected to the outside of the lead screw 3. The lead screw 3 is threadedly connected to a sleeve 4. When the lead screw 3 rotates, it moves linearly along the axis of the lead screw 3, which drives the connecting rod 5 and the clamping rod to move in the opposite direction, so as to realize the material picking mechanism to pick up the material. The lower part of the sleeve 4 is fixedly connected to the connecting rod 5, which connects the sleeve 4 and the clamping rod a6, and at the same time provides an installation position for the rotating component 7 and transmits the movement of the sleeve 4. The front and rear sides of the connecting rod 5 are fixedly connected to the clamping rod a6, and multiple sets are provided for clamping the workpiece and fixing the workpiece during the picking process. The upper part of the connecting rod 5 is provided with the rotating component 7.

[0030] Reference Figures 1-3The rotating assembly 7 includes a support member 71 that rotates through the inner wall of the connecting rod 5, used to support and install components such as the operating member 73, spring 75, and moving member 77. It can also rotate on the connecting rod 5, driving the clamping rod b78 to rotate to adapt to the specifications of the workpiece. A bottom cover 72 is fixedly installed on the lower part of the support member 71 by bolts, used to install the support member 71 on the inner wall of the connecting rod 5. Two sets of operating members 73 are slidably connected to the inner wall of the support member 71. The operating members 73 are L-shaped, and an arc-shaped baffle is provided on the outer side of the operating members 73. A spring 75 is provided on the opposite side of the two sets of operating members 73. By compressing the spring 75, the plug-in member 74 is disengaged from the slot 76, realizing the angle adjustment of the support member 71, thereby adjusting the position and angle of the clamping rod b78 to adapt to workpieces in different positions and angles. The spring 75 causes the plug-in member 74 to engage in the slot 76, locking the angle of the support member 71.

[0031] Reference Figures 2-4 An insert 74 is fixedly connected to the outside of the operating component 73. The insert 74 is shaped like an isosceles trapezoid and engages with the slot 76 on the connecting rod 5 to lock the rotation angle of the support component 71, ensuring the stability of the support component 71 when clamping the workpiece. The upper part of the connecting rod 5 has multiple slots 76 that engage with the insert 74, providing multiple slot positions at different angles so that the support component 71 can be locked at different angles to accommodate the workpiece. The operating component 73 engages with the inner wall of the slot 76. A movable component 77 is slidably connected to the inner wall of the support component 71. By adjusting the position of the movable component 77, the length of the clamping rod b78 can be adjusted so that the clamping area formed by the clamping rod b78 and the clamping rod a6 can accommodate workpieces of different thicknesses. The lower part of the movable component 77 is fixedly connected to the clamping rod b78, which cooperates with the clamping rod a6 to clamp the workpiece. It can move with the movable component 77 and rotate with the support component 71, preventing the workpiece from tipping over on the outside, and simultaneously achieving clamping of workpieces of different thicknesses and positions.

[0032] Reference Figures 1-3 The support member 71 is provided with an adjustment component 8 on its upper part. The adjustment component 8 includes a set screw 82, which is threaded to the inner wall of the support member 71. A limit hole 81 is opened on the outer side of the moving member 77. The lower part of the set screw 82 passes through the limit hole 81. Multiple sets of limit holes 81 are opened evenly through the outer side of the moving member 77. By cooperating with the limit hole 81 on the outer side of the moving member 77, the position of the moving member 77 can be fixed, and the length of the moving member 77 can be adjusted, thereby adjusting the position of the clamping rod b78 to adapt to workpieces of different thicknesses. A torsion cap is provided on the upper part of the set screw 82 for easy manual operation.

[0033] Working principle: When in use, after the drive mechanism 2 is started, the drive screw 3 is rotated. Since the screw 3 and the sleeve 4 are threadedly connected, the sleeve 4 will move linearly along the axis of the screw 3, which in turn drives the connecting rod 5, the clamping rod a6 and the rotating assembly 7 to move in the opposite direction, realizing the movement of the material picking mechanism. The sleeve 4 drives the clamping rod a6 to move towards the workpiece. At the same time, the clamping rod b78 in the rotating assembly 7 cooperates with the clamping rod a6 to form a clamping area, completing the initial positioning of the workpiece.

[0034] The operator can press the arc-shaped baffle of the operating component 73 to compress the spring 75 and disengage the connector 74 from the slot 76. At this time, the support component 71 can rotate on the connecting rod 5, causing the clamping rod b78 to conform to the inclined surface of the workpiece. After adjusting to a suitable angle, the operator can release the operating component 73, and the spring 75 will return to its original position, pushing the connector 74 into the corresponding slot 76 and locking the rotation angle of the support component 71.

[0035] Clamping rod a6 is symmetrically fixed to the front and rear sides of connecting rod 5, and clamping rod b78 is connected to support member 71 through moving part 77 to form a symmetrical clamping structure. When clamping a workpiece with an offset center of gravity, the symmetrically distributed clamping rods can balance the lateral torque and prevent tipping due to instability of the center of gravity.

[0036] At the same time, loosen the set screw 82, and the moving part 77 slides in the support 71, changing the distance between the clamping rod b78 and the clamping rod a6. Tighten the set screw 82 so that it passes through the corresponding limiting hole 81, fix the position of the moving part 77, and complete the adjustment of the clamping range.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
