Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder clamping technology, specifically to a convenient clamping device for hydraulic cylinder processing. Background Technology

[0002] Hydraulic cylinders require repositioning during machining, necessitating a clamping device to hold and secure them. Existing clamping devices often employ external jaws or jigs, using an external robotic arm or hydraulic rod to drive the clamping blocks to grip the cylinder from the outside. When external force acts on the cylinder's outer wall, it easily causes the cylinder's center of gravity to deviate from its axis. Furthermore, the clamping surfaces of existing jigs are often elongated or planar, resulting in minimal contact area with the cylindrical cylinder, insufficient friction, and a tendency for the cylinder to rotate or slip. To address these issues, this invention provides a convenient clamping device for hydraulic cylinder machining. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a convenient clamping device for hydraulic cylinder processing. By setting multiple internal support components, the hydraulic cylinder can be clamped and fixed from multiple points inside against the inner wall of the hydraulic cylinder. This not only increases friction but also ensures that the center of gravity of the cylinder does not shift, thereby guaranteeing the stability of the clamping.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a convenient clamping device for machining hydraulic cylinders, comprising:

[0005] A base rod, wherein a slot is provided on the base rod and the opening of the slot is located on one end face of the base rod;

[0006] A telescopic rod, which is slidably installed inside the slot;

[0007] Multiple internal support components are installed between the base rod and the telescopic rod, and arranged in a circumferential array around the base rod;

[0008] When the telescopic rod slides into the cavity, the inner support assembly moves away from the telescopic rod and presses against the inner wall of the hydraulic cylinder.

[0009] Preferably, the internal support assembly includes:

[0010] The upper rod, the upper end of which is hinged to the end of the base rod near the opening of the slot;

[0011] The lower rod is hinged to the side wall of the telescopic rod away from the bottom wall of the empty groove;

[0012] The upper rod and the lower rod are hinged to each other.

[0013] Preferably, the ends of the upper and lower rods that are hinged to each other are fixedly connected with elastic sleeves.

[0014] Preferably, the elastic sleeve has a hollow structure and is filled with air.

[0015] Preferably, a plurality of protrusions are fixedly connected to the side of the elastic sleeve.

[0016] Preferably, a protrusion is provided above the connection between the lower rod and the telescopic rod, and the protrusion is fixedly connected to the side of the telescopic rod.

[0017] Preferably, both the upper and lower rods are provided with arc-shaped portions, and the arc-shaped portions are made of an elastic material.

[0018] Preferably, the arc-shaped portion is designed as a hollow structure.

[0019] Preferably, a motor is installed on the bottom sidewall of the empty trough, and a screw is fixedly connected to the motor shaft of the motor, and the screw is threadedly connected to the telescopic rod.

[0020] Preferably, the telescopic rod is prism in shape.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention, through the arrangement of a telescopic rod, an upper rod, and a lower rod, enables the connection between the upper and lower rods to move away from the base rod when the telescopic rod slides into the cavity, pressing against the inner wall of the hydraulic cylinder and fixing the hydraulic cylinder from the inside. This ensures that the center of gravity of the cylinder will not shift, and multiple evenly distributed contact points are formed with the inner wall of the hydraulic cylinder, improving the stability of the clamping.

[0023] This invention achieves a hollow structure for the elastic sleeve, filled with air, through the design of the elastic sleeve and the arc-shaped portion, which can buffer impact force; the raised strips on the surface of the elastic sleeve enhance friction and further improve clamping stability. The arc-shaped portion is made of elastic material and has a hollow structure, which can disperse the clamping force through elastic deformation when the upper and lower rods press against the inner wall of the hydraulic cylinder, avoiding damage to the hydraulic cylinder due to excessive clamping force.

[0033] 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.

[0034] This utility model provides a convenient clamping device for machining hydraulic cylinders, such as... Figures 1 to 6 As shown.

[0035] Example 1:

[0036] A convenient clamping device for machining hydraulic cylinders includes a base rod 1 with a slot 2 on the base rod 1. The opening of the slot 2 is located on the end face of the base rod 1. A telescopic rod 3 is slidably installed inside the slot 2. The telescopic rod 3 can slide along the long side of the slot wall. Multiple inner support components are provided on the outer side of the base rod 1. The multiple inner support components are arranged in a circumferential array around the base rod 1. When the telescopic rod 3 slides into the slot 2, the inner support components move away from the telescopic rod 3 and press against the inner wall of the hydraulic cylinder, thereby clamping and fixing the hydraulic cylinder.

[0037] The internal support assembly includes an upper rod 4 and a lower rod 5. The upper end of the upper rod 4 is hinged to the base rod 1 via an ear plate fixedly connected to the base rod 1. The hinge point between the upper rod 4 and the base rod 1 is located on the side wall of the base rod 1 at the end closest to the opening of the slot 2. The lower end of the lower rod 5 is hinged to the telescopic rod 3 via an ear plate fixedly connected to the telescopic rod 3. The hinge point between the lower rod 5 and the telescopic rod 3 is located on the side wall of the telescopic rod 3 at the end furthest from the bottom of the slot 2. The end of the upper rod 4 furthest from the hinge point with the base rod 1 and the end of the lower rod 5 furthest from the hinge point with the telescopic rod 3 are hinged together.

[0038] When the telescopic rod 3 slides into the cavity 2, the hinge point of the upper rod 4 and the lower rod 5 will slide away from the telescopic rod 3, thereby driving the hinge point of the upper rod 4 and the lower rod 5 to press against the inner wall of the hydraulic cylinder, thus clamping and fixing the inside of the hydraulic cylinder.

[0039] A protrusion 8 is provided above the hinge point between the lower rod 5 and the telescopic rod 3. The protrusion 8 is fixedly installed on the telescopic rod 3. The protrusion 8 can make the end of the lower rod 5 that is close to the upper rod 4 always tilted away from the telescopic rod 3. When the telescopic rod 3 moves into the cavity 2, the hinge point between the upper rod 4 and the lower rod 5 will slide stably away from the telescopic rod 3.

[0040] Example 2:

[0041] Based on Embodiment 1, in order to improve the stability of clamping, elastic sleeves 6 are fitted onto the opposite ends of the upper rod 4 and the lower rod 5. The elastic sleeves 6 are hollow structures filled with air. When clamping the hydraulic cylinder, the elastic sleeves 6 can adapt to the shape of the inner wall of the hydraulic cylinder and fit tightly against the inner wall of the hydraulic cylinder. At the same time, they can buffer rigid impacts and avoid damage to the inner wall of the hydraulic cylinder. Multiple protrusions 7 are fixedly connected to the side of the elastic sleeves 6. The protrusions 7 can increase the friction between the elastic sleeves 6 and the inner wall of the hydraulic cylinder, thereby ensuring stable clamping of the hydraulic cylinder.

[0042] Both the upper rod 4 and the lower rod 5 are provided with arc-shaped parts. The arc-shaped parts are made of elastic materials (such as spring steel) and have a hollow structure. When the upper rod 4 and the lower rod 5 are pressed against the inner wall of the hydraulic cylinder, if the pressing force is greater than the set value (that is, greater than the force required to make the arc-shaped parts produce elastic deformation), the arc-shaped parts will produce corresponding elastic deformation. This can avoid excessive pressing force on the hydraulic cylinder, ensuring stable clamping while preventing damage to the hydraulic cylinder due to excessive pressing force.

[0043] Example 3:

[0044] A motor 9 is installed on the bottom side wall of the slot 2. A screw 10 is fixedly installed on the motor shaft of the motor 9. The screw 10 is threadedly connected to the telescopic rod 3. The rotation of the motor 9 can control the telescopic rod 3 to slide inside the slot 2. In order to make the telescopic rod 3 slide more stably, the shape of the telescopic rod 3 is set as a prism, ensuring that the telescopic rod 3 can only slide along the long side of the slot wall inside the slot 2. Thus, when the motor 9 drives the screw 10 to rotate, the telescopic rod 3 can slide stably inside the slot 2 without applying torsional force to the inner support assembly, thus protecting the inner support assembly.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
