Description

Technical Field

[0001] This utility model relates to the field of lifting tools, and in particular to a new energy differential shaft gripping mechanism. Background Technology

[0002] Existing gripping mechanisms typically apply clamping force directly to the workpiece during operation to achieve gripping. Since the clamping components are mostly rigid structures, their contact with the workpiece is a rigid action. During the movement of the gripping mechanism, vibration is unavoidable. This vibration can easily cause slight displacement of the mechanism components, leading to relative friction between the workpiece and the clamping components, potentially causing wear on the workpiece. This presents certain limitations in practical applications. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a new energy differential shaft gripping mechanism, which solves the problem of wear caused by the relative friction between the workpiece and the rigid clamping component due to vibration in existing gripping mechanisms.

The lifting base plate is provided with an input shaft gripping device, an intermediate shaft gripping device, and a differential shaft gripping device. The three sets of devices are respectively used to grip the input shaft, intermediate shaft, and differential shaft. Each gripping device includes a clamping component and a driving component. The driving component is used to drive the clamping component to form a clamping grip on the workpiece. The contact area between the clamping component and the workpiece is adapted.

[0005] Optionally, the input shaft gripping device includes a first slide table slidably mounted on the left side of the bottom surface of the lifting base plate. The bottom surface of the first slide table is provided with a first hook and a second cylinder. The first hook has a semi-circular first opening facing the right.

The first pressing block cooperates with the first opening to clamp the input shaft. The first cylinder is fixed on the bottom surface of the first slide table. The first cylinder is arranged in the left-right direction, and its extended end is fixed to the bottom surface of the lifting base plate.

[0006] Optionally, the intermediate shaft gripping device includes a second slide table slidably mounted on the front center of the bottom face of the lifting base plate. The bottom surface of the second slide table is provided with a second hook and a fourth cylinder. The second hook has a semi-circular second opening facing the rear. The fourth cylinder is vertically arranged and its extended end is fixed with a second pressure block facing the second opening. The second pressure block cooperates with the second opening to clamp the intermediate shaft. A third cylinder is fixed on the bottom surface of the second slide table. The third cylinder is arranged in the front-rear direction, and its extended end is fixed to the bottom surface of the lifting base plate.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 6 This embodiment provides a new energy differential shaft gripping mechanism, including a lifting base plate 1. The base plate is respectively provided with an input shaft gripping device, an intermediate shaft gripping device, and a differential shaft gripping device. Before gripping, the input shaft, intermediate shaft, and differential shaft are manually placed into the fixture in sequence to position each shaft. The fixture is then operated to assemble each shaft into place. Then, the lifting device is activated to drive the lifting base plate 1 to descend, so that the input shaft gripping device, intermediate shaft gripping device, and differential shaft gripping device grip the input shaft, intermediate shaft, and differential shaft respectively. Then, the lifting device can be operated to lift the three assembled shafts for movement.

[0018] The input shaft gripping device includes a first slide 2 slidably mounted on the left side of the bottom surface of the lifting base plate 1 via two sets of first linear slide rails. The first slide 2 can slide left and right at the bottom of the lifting base plate 1. The power to drive its sliding comes from the first cylinder 3 fixed on its bottom surface. The first cylinder 3 is arranged in the left and right direction, and the extended end of the first cylinder 3 is fixed to the bottom surface of the lifting base plate 1. Thus, when the first cylinder 3 extends, it can push the first slide 2 to slide to the right, and when the first cylinder 3 retracts, it can pull the first slide 2 to slide to the left.

[0019] A first hook 4 is fixed on the right side of the bottom surface of the first slide 2. The first hook 4 has a semi-circular opening facing the right. A second cylinder 5 is fixed on the first slide 2 directly opposite the first hook 4. The second cylinder 5 is vertically arranged, and a first pressure block 6 is fixed to its extended end. The axis of the first pressure block 6 is collinear with the axis of the imaginary cylinder surrounded by the first opening. Before hooking the input shaft, the second cylinder 5 is in a retracted state, and the first cylinder 3 is also in a retracted state. The lifting device is operated to drive the lifting base plate 1 to descend until it is in place. Then the first cylinder 3 extends and pushes the first hook 4 closer to the input shaft until the first hook 4 is engaged in the locking position on the input shaft. Then the second cylinder 5 extends and pushes the first pressure block 6 to press on the top of the input shaft, cooperating with the first hook 4 to hook the input shaft.

[0020] The intermediate shaft gripping device includes a second slide 7 slidably mounted on the front center of the bottom of the lifting base plate 1. The second slide 7 can slide back and forth in the center of the bottom of the lifting base plate 1. The second slide 7 is slidably connected to the lifting base plate 1 through two sets of second linear slide rails. A third cylinder 8 is fixed on the bottom surface of the second slide 7. The third cylinder 8 is arranged in the back and forth direction. The extended end of the third cylinder 8 is fixed to the bottom surface of the lifting base plate 1. Similarly, driving the third cylinder 8 to extend can push the second slide 7 to slide from front to back. When the third cylinder 8 retracts, it pulls the second slide 7 to slide from back to front.

[0021] A second hook 9 is fixed to the rear side of the bottom surface of the second slide 7. The second hook 9 has a semi-circular second opening facing the rear. A fourth cylinder 10 is fixed on the second slide 7 directly opposite the second opening. It is vertically arranged, and a second pressure block 11 is fixed to its extended end. The axis of the second pressure block 11 is collinear with the axis of the imaginary cylinder surrounded by the second opening. Before hooking the intermediate shaft, the third cylinder 8 is in a retracted state, and the fourth cylinder 10 is also in a retracted state. The lifting device is operated to drive the lifting base plate 1 to descend until it is in place. Then the third cylinder 8 extends and pushes the second slide 7 to slide from front to back, so that the second hook 9 is engaged in the locking position of the intermediate shaft. Then the fourth cylinder 10 extends and presses the second pressure block 11 against the top of the intermediate shaft, hooking the intermediate shaft.

[0022] The differential shaft gripping device includes a third slide 12 slidably mounted on the right side of the bottom surface of the lifting base plate 1 via two sets of third linear slide rails. The third slide 12 faces the first slide 2. A fifth cylinder 13 is fixed to the bottom surface of the third slide 12. The fifth cylinder 13 is arranged in a left-right direction, and its extended end is fixed to the bottom surface of the lifting base plate 1. Driving the fifth cylinder 13 to extend it can push the third slide 12 to slide from right to left. A sixth cylinder 14 is fixed to the top surface of the third slide 12 in a longitudinal direction. The extended end of the sixth cylinder 14 extends through the third slide 12 to the bottom of the third slide 12. A connecting sleeve 15 is fixed to the bottom surface of the third slide 12 and is fitted onto the sixth cylinder 14. On the outer side of the extended end of 4, the bottom of the connecting sleeve 15 is fixed with an inverted conical core sleeve 16. The extended end of the sixth cylinder 14 extends through the connecting sleeve 15 and the core sleeve 16 to the bottom of the core sleeve 16 and is fixed with a tensioning sleeve 17. The inner wall of the tensioning sleeve 17 is conical and cooperates with the core sleeve 16. The tensioning sleeve 17 has through grooves at equal angles in the circumferential direction. When the lifting base plate 1 descends, the tensioning sleeve 17 is inserted into the hole of the differential shaft. Then the sixth cylinder 14 retracts and pulls the tensioning sleeve 17 upward. The conical surface of the core sleeve 16 pushes the conical surface of the tensioning sleeve 17, forcing the tensioning sleeve 17 to expand outward and abut against the inner wall of the hole of the differential shaft, supporting the differential shaft and completing the gripping work of the differential shaft.

[0023] On the lifting base plate 1, strip-shaped clearance grooves are provided at the positions of the second cylinder 5, the fourth cylinder 10 and the sixth cylinder 14. The second cylinder 5, the fourth cylinder 10 and the sixth cylinder 14 extend through the clearance grooves to the top of the lifting base plate 1 to avoid the second cylinder 5, the fourth cylinder 10 and the sixth cylinder 14 when each slide moves.

[0024] After the hooking and gripping of the three axes are completed simultaneously, the lifting base plate 1 can be driven to move upward to perform synchronous lifting of the three axes.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
