Detailed Implementation

[0030] Please see Figure 1-12 ,

[0031] Example 1: A hydraulic separation clamp with horizontal rotation operation includes a cylinder 1, and a sealing head 15 is provided at the end of the cylinder 1. The sealing head 15 is connected to the cylinder 1 through a bearing seat 2.

[0032] A side handle 3 is provided on the outer side of the bearing housing 2. A bearing retaining ring 5 is provided at the junction of the bearing housing 2 and the sealing head 15. The bearing housing 2 and the end of the cylinder 1 are rotatably connected by a connecting bearing 6. A perforated elastic retaining ring 7 is provided on the side of the connecting bearing 6. A connector connecting seat 8 is provided on the cylinder 1. A B oil inlet 9 is provided on the side of the connector connecting seat 8. The B oil inlet 9 is connected to the cylinder 1 by a provided oil inlet oblique hole 10.

[0033] A guide rod 11 is slidably arranged inside the cylinder 1. The end of the guide rod 11 passes through the middle of the sealing head 15. The end of the guide rod 11 is connected to the clamp core 12. A rotating connecting seat 13 is sleeved on the outside of the sealing head 15. Two clamping pieces 14 are symmetrically rotated on both sides of the inner wall of the rotating connecting seat 13. The clamping pieces 14 are attached to both sides of the clamp core 12. An oil filling port A 16 is provided on the side of the end of the cylinder 1. A handle mounting plate 17 is provided at the end of the cylinder 1. A switch handle 4 is installed on the handle mounting plate 17.

[0034] Example 2: The difference between this example and Example 1 is that a sealing ring is provided at the middle part of the guide rod 11 penetrating the sealing head 15.

[0035] This makes the seal between the guide rod 11 and the sealing head 15 more tight.

[0036] Example 3: The difference between this example and Example 1 is that the clamp core 12 is triangular pyramidal in shape, and the end of the clamp core 12 is connected to the guide rod 11 by screws.

[0037] This allows the guide rod 11 to better engage with the clamping plate 14 when pushing the clamping core 12 forward.

[0038] Example 4: The difference between this example and Example 1 is that the handle mounting plate 17 is L-shaped and bent, and the handle mounting plate 17 is connected to the cylinder 1 by bolts.

[0039] This makes it easier for users to install the handle mounting plate 17 and to rotate the switch handle 4.

[0040] In this embodiment, the equipment on the market today is too chaotic, and the existing technical structure is relatively complex, the maintenance cost is high, the product coverage is limited, the replacement of parts is difficult, and the service life is short.

[0041] In summary, in practical implementation, this device converts hydraulic energy into mechanical energy to perform linear reciprocating motion, allowing hydraulic oil to enter the cylinder 1 through oil inlet A 16. Since the clamp core 12 and the clamping plate 14 are in contact with each other, pushing the guide rod 11 drives the clamp core 12 forward, causing the device to switch from a closed state to an open state. Hydraulic oil enters the cylinder 1 through oil inlet B 9, thereby pushing the guide rod 11 to drive the clamp core 12 backward. When the guide rod 11 moves backward to contact the cylinder 1, the guide rod 11 stops moving backward, and the hydraulic separation clamp switches from an open state to a closed state.

[0042] Compared to traditional hydraulic splitters, this improvement optimizes the structure of the hydraulic splitters, making the operation easier for workers and reducing their fatigue to some extent.

[0043] Firstly, the improved hydraulic separation clamp has an added bearing seat 2 to provide a rotation function. This allows workers to separate castings in more diverse ways during operation. This device is designed for use by customers on the scale plate line. When castings reach the separation area through the scale plate line, it is not possible to ensure that all castings are oriented in the same direction. This results in some castings requiring the hydraulic separation clamp to be rotated to be separated. However, because the old structure does not have a rotation function, the entire separation clamp must be rotated to achieve the separation purpose. Over time, this will greatly increase worker fatigue and significantly reduce production efficiency.

[0044] This improvement adds a connecting bearing 6 that can be used for rotation, as described above. Figure 10 The component shown allows for the hydraulic separation pliers to rotate for separation while the switch handle 4 remains stationary. Additionally, threads are added to the side handle 3, which connects to the rotating structure, as described above. Figure 7 As shown, this allows the side handle 3 to be removed and placed inside the equipment packaging box before transportation, which greatly saves packaging space. Secondly, the connection method of our oil pipe joint has also been optimized. Without changing the position of the oil pipe joint, the connection has been modified. Because of the addition of the rotating structure, the original position of the oil pipe joint will interfere. This is achieved by machining the oil injection oblique hole 10 on the cylinder 1 as described above. Figure 4 and the above-mentioned 8 parts including the joint connector base. Figure 12 This is used to ensure the joint position. The final modified effect is shown in structural diagram 1.

[0045] The advantages are as follows: First, the appearance will not change significantly without affecting the operation of the pliers. Second, since the pliers need to work via a connecting oil pipe, any alteration to the oil pipe connector position could obstruct the operator's operation and view. Finally, because the new structure adds a rotating function, the position and assembly method of the switch handle 4 will not be as convenient as before. Considering ergonomics, we adopted a new switch handle 4, as described above. Figure 8 By modifying the parts shown above, the equipment usage problems will be avoided.
