Description

Technical Field

[0001] This utility model relates to the field of cylinder clamping technology, and in particular to a multi-jaw adaptive tensioning clamp for cylinder bores. Background Technology

[0002] In the field of mechanical manufacturing, especially in the processing of parts with cylindrical internal cavity structures such as engine cylinder blocks, compressor housings, and hydraulic pump valve bodies, high-precision positioning and clamping operations are often required for the workpieces.

[0003] In the existing technology, the fixed jaw structure designed for a single specification is only suitable for workpieces within a specific diameter range. When the product model changes, the entire tooling must be replaced, resulting in long equipment downtime and high changeover costs, which makes it difficult to meet the needs of modern flexible production. At the same time, the coarse clamping achieved by manually adjusting the jaw position leads to uneven clamping force distribution, causing deformation of thin-walled parts. Therefore, a multi-jaw adaptive tensioning fixture for cylinder bores is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-jaw adaptive tensioning clamp for cylinder bores, which solves the problems mentioned above.

[0005] To achieve the above objectives, a multi-jaw adaptive tensioning clamp for cylinder bores is provided, comprising a mounting plate, a cylinder and a fixing rod fixedly connected to the upper side of the mounting plate, a connecting plate fixedly connected to the upper end of the fixing rod, a first connecting block fixedly connected to the lower side of the mounting plate, an auxiliary plate fixedly connected to the lower side of the cylinder, a second connecting block connected to the outer side of the auxiliary plate via a rotating shaft, a fixing plate installed between the first and second connecting blocks, and a jaw connected to the fixing plate via a rotating shaft; the jaw is generally L-shaped, with a first connecting plate at its upper end, a hanging plate fixedly connected to the inner side of the jaw, the hanging plate being L-shaped, with a second connecting plate fixedly connected to its upper side, the jaw mounted on the fixing plate via the first and second connecting plates, a sleeve portion at the lower end of the jaw, and an elastic rubber strip installed between the sleeve portion and the hanging plate.

[0006] According to the aforementioned cylinder bore multi-jaw adaptive tensioning clamp, the cylinder is fixed to the mounting plate by bolts, the cylinder is a thin-shaped cylinder, and both ends of the fixing rod are fixedly connected to the mounting plate and the connecting plate by bolts.

[0008] According to the cylinder bore multi-jaw adaptive tensioning clamp, the first connecting block is fixed to the mounting plate by bolts, and the second connecting block is U-shaped in general.

[0009] According to the aforementioned cylinder bore multi-jaw adaptive tensioning clamp, the elastic rubber strip is made of rubber or silicone, and its upper and lower ends are respectively installed on the mounting plate and the sleeve part.

[0010] According to the aforementioned cylinder bore multi-jaw adaptive tensioning clamp, both the hook plate and the sleeve part are arc-shaped at their corner positions.

[0011] According to the cylinder bore multi-jaw adaptive tensioning clamp, there are three jaws that are evenly distributed, and the elastic rubber strips on the three jaws are all set inward.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides a multi-jaw adaptive tensioning clamp for cylinder bores, which includes a mounting plate 1. A cylinder 2 and a fixing rod 3 are fixedly connected to the upper side of the mounting plate 1. A connecting plate 4 is fixedly connected to the upper end of the fixing rod 3. The cylinder 2 is fixed to the mounting plate 1 by bolts. The cylinder 2 is a thin cylinder, which can effectively save space and make the structure of the whole device more compact and reasonable. Both ends of the fixing rod 3 are fixedly connected to the mounting plate 1 and the connecting plate 4 by bolts. The double bolt fixing design greatly enhances the rigidity and stability of the structure, so that it can maintain good mechanical performance under complex working environment and high-intensity working load.

[0025] A first connecting block 6 is fixedly connected to the lower side of the mounting plate 1. The output end of the cylinder 2 is located on the lower side of the mounting plate 1 and is fixedly connected to an auxiliary plate 5. A second connecting block 9 is connected to the outer side of the auxiliary plate 5 through a rotating shaft. There are three of each of the first connecting blocks 6 and the second connecting blocks 9, which are evenly distributed on the mounting plate 1 and the auxiliary plate 5, ensuring the even distribution of force and making the entire device more balanced and stable during movement. When the cylinder 2 works, the extension and retraction movement of its output end will be directly transmitted to the auxiliary plate 5, causing it to move up and down, thereby triggering a series of chain reactions to achieve effective clamping of the workpiece.

[0026] The first connecting block 6 is fixed to the mounting plate 1 by bolts. The second connecting block 9 is U-shaped. A fixing plate 8 is installed between the first connecting block 6 and the second connecting block 9. Three grippers 7 are connected to the fixing plate 8 via a rotating shaft. The elastic rubber strips 10 on the three grippers 7 are all set inwards. The symmetrical layout of the grippers 7 ensures that the clamping force is evenly applied to all parts of the workpiece, effectively preventing workpiece deformation or damage caused by uneven force. Each gripper 7 is connected to the fixing plate 8 via a rotating shaft. This connection method gives the gripper 7 a certain degree of rotational freedom, allowing it to automatically adjust its angle according to the shape and size of the workpiece, achieving adaptive clamping. The grippers 7 are L-shaped overall. This unique shape design increases the structural strength, facilitates cooperation with other components, and improves the reliability of the entire system.

[0027] The upper end of the gripper 7 is provided with a first connecting plate 71, and a hanging plate 73 is fixedly connected to the inner side of the gripper 7. The hanging plate 73 is L-shaped, and a second connecting plate 72 is fixedly connected to its upper side. The gripper 7 is mounted on the fixed plate 8 through the first connecting plate 71 and the second connecting plate 72. The lower end of the gripper 7 is provided with a sleeve part 74. Both the corners of the hanging plate 73 and the sleeve part 74 are arc-shaped to reduce wear and improve clamping accuracy. An elastic rubber strip 10 is installed between the sleeve part 74 and the hanging plate 73. The elastic rubber strip 10 is made of rubber or silicone, and its upper and lower ends are respectively installed on the hanging plate 73 and the sleeve part 74. When the gripper 7 clamps the workpiece, the elastic rubber strip 10 can effectively absorb the impact force and prevent the workpiece surface from being scratched. Damage or injury; the elastic rubber strip 10 and the gripper 7 located between the mounting plate 73 and the sleeve part 74 are hollow, while the sleeve part 74 is solid. This structural design reduces the overall weight while ensuring sufficient strength and rigidity, allowing the gripper 7 to move flexibly and maintain a stable shape during operation. When high-precision positioning and clamping are required, the sleeve part 74 clamps and fixes the part, while the elastic rubber strip 10 further protects the part. When clamping irregularly shaped parts, the elastic rubber strip 10 in the middle position clamps and fixes them. Under its action, the elastic rubber strip 10 deforms and fixes the part, showing good adaptability and wide application range.

[0028] Working principle: In use, the device is installed on other components via the connecting plate 4. Then, the cylinder 2 is activated, which drives the auxiliary plate 5 to move up and down. When the auxiliary plate 5 moves downward, the grippers 7 move inward under the action of the first connecting block 6, the fixing plate 8, and the second connecting block 9. When high-precision positioning and clamping are required, the sleeve part 74 clamps and fixes the parts, and the elastic rubber strip 10 further protects the parts. When clamping irregularly shaped parts, the elastic rubber strip 10 in the middle position clamps and fixes them. Under its action, the elastic rubber strip 10 deforms and fixes the parts. It has good adaptability and a wide range of applications.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
