Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to a clamping device with a changeable clamping surface shape. Background Technology

[0002] The clamping surfaces of commonly used clamping devices are usually of a fixed shape, such as straight lines or arcs. However, when the object being clamped is irregularly shaped, the clamping contact points are often not evenly distributed on the surface of the object, causing the clamping force to concentrate on a single contact point. This type of action usually causes damage or deformation to the surface of the object being clamped. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a clamping device that can change the shape of the clamping surface, thereby solving the technical problem of damage or deformation of the surface of the clamped object caused by the fixed shape of the clamping surface.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a clamping device with a changeable clamping surface shape, comprising a control platform, a clamping body, hydraulic cylinders, and a hydraulic pump station; the clamping body comprises a first adjustment component and a second adjustment component arranged opposite to each other, both disposed on the upper surface of the control platform; the upper surfaces of the first adjustment component and the second adjustment component are each provided with several hydraulic cylinders arranged in parallel; the cylinder heads of the hydraulic cylinders on the upper surfaces of the first adjustment component and the second adjustment component are arranged facing each other, and the hydraulic cylinders are connected to the hydraulic pump station through oil pipes.

[0005] In this configuration, several hydraulic cylinders on the upper surface of the first adjustment component are connected in series via oil pipes, thereby forming a hydraulic circuit with the hydraulic pump station via oil pipes; similarly, several hydraulic cylinders on the upper surface of the second adjustment component are connected in series via oil pipes, thereby forming a hydraulic circuit with the hydraulic pump station via oil pipes.

[0006] The cylinder head of the hydraulic cylinder is spherical.

[0007] The hydraulic pump station is equipped with a pressure gauge, which is connected to the outlet of the hydraulic pump station.

[0008] The fixture body further includes a base, the upper surface of which is provided with an upward-facing first opening groove. The first adjustment component and the second adjustment component are both placed in the first opening groove. The second adjustment component and the first adjustment component are symmetrical to each other. The first adjustment component includes a first moving block, a first adjusting bolt, a second moving block, and a second adjusting bolt. Several first adjusting bolts are provided. One end of the first adjusting bolt is fixed to the side of the first moving block, and the other end of the first adjusting bolt is embedded in the lateral side of the first opening groove. The first adjusting bolt is then locked to the inner and outer ends of the lateral side of the first opening groove by a nut. The lateral distance of the first moving block in the first opening groove can be adjusted by adjusting the position of the first adjusting bolt on the side of the first opening groove.

[0009] The upper surface of the first movable block is provided with a second opening groove; the second opening groove does not penetrate through both ends of the first movable block, the second movable block is placed in the second opening groove, one end of the second adjusting bolt is fixed to the side of the second movable block, and the other end of the second adjusting bolt is embedded in the longitudinal side of the second movable block. Then, the second adjusting bolt is locked to the inner and outer ends of the longitudinal side of the second opening groove by a nut. The longitudinal distance of the second movable block in the second opening groove can be adjusted by adjusting the position of the second adjusting bolt on the side of the second opening groove.

[0010] The upper surface of the second moving block is provided with a third opening groove, which is arranged horizontally. Several third opening grooves are arranged side by side, and the structure of the third opening groove is adapted to the structure of the hydraulic cylinder.

[0011] The beneficial effects of this utility model are as follows: Compared with the original clamping device, the clamping surface of the clamping device provided by this utility model is composed of the cylinder heads of several hydraulic cylinders arranged in parallel. Since the stroke of each hydraulic cylinder head is independent, the clamping surface of the clamping device can adapt to various irregularly shaped objects, effectively avoiding damage or deformation to the surface of the clamped object; at the same time, through the first adjustment component and the second adjustment component, the relative position between the hydraulic cylinder and the clamped object can be adjusted to ensure that the hydraulic cylinder has sufficient stroke to clamp the clamped object.

[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1-2 As shown, the technical solution adopted by this utility model is as follows: a clamping device with a changeable clamping surface shape, comprising a control platform 1, a clamping body 2, a hydraulic cylinder 3, and a hydraulic pump station 4; the clamping body 2 comprises a first adjustment component 21 and a second adjustment component 22 arranged opposite to each other, and both are disposed on the upper surface of the control platform 1; several hydraulic cylinders 3 are arranged in parallel on the upper surfaces of the first adjustment component 21 and the second adjustment component 22; the cylinder heads of the hydraulic cylinders 3 on the upper surfaces of the first adjustment component 21 and the second adjustment component 22 are arranged opposite to each other, and the hydraulic cylinders 3 are connected to the hydraulic pump station 4 through oil pipes.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: The clamping surface of the clamping device provided by this utility model is composed of the cylinder heads of several hydraulic cylinders 3 arranged in parallel. Since the stroke of each hydraulic cylinder head is independent, the clamping surface of the clamping device can adapt to various irregularly shaped objects to be clamped, effectively avoiding damage or deformation to the surface of the clamped object; at the same time, through the first adjustment component 21 and the second adjustment component 22, the relative position between the hydraulic cylinder 3 and the object to be clamped can be adjusted to ensure that the hydraulic cylinder has sufficient stroke to clamp the object.

[0021] Furthermore, several hydraulic cylinders 3 on the upper surface of the first adjustment component 21 are connected in series by oil pipes, and thus form a hydraulic circuit with the hydraulic pump station 4 through the oil pipes; several hydraulic cylinders 3 on the upper surface of the second adjustment component 22 are connected in series by oil pipes, and thus form a hydraulic circuit with the hydraulic pump station 4 through the oil pipes.

[0022] As can be seen from the above description, the several hydraulic cylinders 3 arranged in parallel are controlled by an oil inlet and an oil outlet, so that the clamping force of each hydraulic cylinder 3 is consistent, ensuring that the clamped object is subjected to a uniform clamping force.

[0023] Furthermore, the cylinder head of the hydraulic cylinder 3 is spherical.

[0024] As can be seen from the above description, using a spherical cylinder head allows the cylinder head to fit more closely to the object being clamped, making it less likely to damage the surface of the object being clamped.

[0025] Furthermore, a pressure gauge 41 is installed on the hydraulic pump station 4, and the pressure gauge 41 is connected to the outlet of the hydraulic pump station 4.

[0026] As can be seen from the above description, the pressure gauge 41 enables the operator to accurately control the pressure at the outlet of the hydraulic pump station, thereby ensuring the clamping force of the hydraulic cylinder.

[0027] Furthermore, the clamp body 2 also includes a base 23, the upper surface of which is provided with an upward-facing first opening groove 231. The first adjustment component 21 and the second adjustment component 22 are both placed in the first opening groove 231. The second adjustment component 22 and the first adjustment component 21 are symmetrical to each other. The first adjustment component 21 includes a first moving block 211, a first adjusting bolt 212, a second moving block 213, and a second adjusting bolt 214. Several first adjusting bolts 212 are provided. One end of the first adjusting bolt 212 is fixed to the side of the first moving block 211, and the other end of the first adjusting bolt 212 is embedded in the lateral side of the first opening groove 231. The first adjusting bolt 212 is then locked to the inner and outer ends of the lateral side of the first opening groove 231 by a nut. By adjusting the position of the first adjusting bolt 212 on the side of the first opening groove 231, the lateral distance of the first moving block 211 in the first opening groove 231 can be adjusted.

[0028] The upper surface of the first movable block 211 is provided with a second opening groove 211a; the second opening groove 211a does not penetrate through both ends of the first movable block 211, the second movable block 213 is placed in the second opening groove 211a, one end of the second adjusting bolt 214 is fixed to the side of the second movable block 213, and the other end of the second adjusting bolt 214 is embedded in the longitudinal side of the second movable block 213. Then, the second adjusting bolt 214 is locked to the inner and outer ends of the longitudinal side of the second opening groove 211a by a nut. By adjusting the position of the second adjusting bolt 214 on the side of the second opening groove 211a, the longitudinal distance of the second movable block 213 in the second opening groove 211a can be adjusted.

[0029] As can be seen from the above description, the relative distance between the first adjusting component 21 and the second adjusting component 22 can be adjusted by the first adjusting bolt 212, thereby ensuring that it can accommodate objects of different widths; and by adjusting the second adjusting bolt 214, the position of each hydraulic cylinder 3 on the surface of the clamped object can be adjusted, thereby ensuring that the hydraulic cylinder 3 is clamped in the appropriate position.

[0030] Furthermore, the upper surface of the second moving block 213 is provided with a third opening groove 213a, which is arranged horizontally, and several third opening grooves 213a are arranged side by side. The structure of the third opening groove 213a is adapted to the structure of the hydraulic cylinder 3.

[0031] As can be seen from the above description, installing the hydraulic cylinder 3 in the third opening groove 213a can ensure that the hydraulic cylinder 3 is not easily displaced during the clamping process, thereby ensuring the stability during clamping.

[0033] This invention can be applied to objects with irregular surfaces, such as clamping round objects and adjustable wrenches.

[0034] Please refer to Figures 1-2 A clamping device with an adjustable clamping surface shape includes a control platform 1, a clamp body 2, hydraulic cylinders 3, and a hydraulic pump station 4. The clamp body 2 includes a first adjustment component 21 and a second adjustment component 22 arranged opposite to each other, both disposed on the upper surface of the control platform 1. Several hydraulic cylinders 3 are arranged in parallel on the upper surfaces of the first adjustment component 21 and the second adjustment component 22. The cylinder heads of the hydraulic cylinders 3 on the upper surfaces of the first adjustment component 21 and the second adjustment component 22 are arranged facing each other, and the cylinder heads of the hydraulic cylinders 3 are spherical. The hydraulic cylinders 3 are connected to the hydraulic pump station 4 through oil pipes. A pressure gauge 41 is disposed on the hydraulic pump station 4, and the pressure gauge 41 is connected to the outlet of the hydraulic pump station 4.

[0035] The clamp body 2 also includes a base 23. The upper surface of the base 23 is provided with an upward-facing first opening groove 231. The first adjustment component 21 and the second adjustment component 22 are both placed in the first opening groove 231. The second adjustment component 22 and the first adjustment component 21 are symmetrical to each other. The first adjustment component 21 includes a first moving block 211, a first adjusting bolt 212, a second moving block 213, and a second adjusting bolt 214. Several first adjusting bolts 212 are provided. One end of the first adjusting bolt 212 is fixed to the side of the first moving block 211, and the other end of the first adjusting bolt 212 is embedded in the lateral side of the first opening groove 231. The first adjusting bolt 212 is then locked to the inner and outer ends of the lateral side of the first opening groove 231 by a nut. The lateral distance of the first moving block 211 in the first opening groove 231 can be adjusted by adjusting the position of the first adjusting bolt 212 on the side of the first opening groove 231.

[0036] The upper surface of the first movable block 211 is provided with a second opening groove 211a; the second opening groove 211a does not penetrate through both ends of the first movable block 211, the second movable block 213 is placed in the second opening groove 211a, one end of the second adjusting bolt 214 is fixed to the side of the second movable block 213, and the other end of the second adjusting bolt 214 is embedded in the longitudinal side of the second movable block 213. Then, the second adjusting bolt 214 is locked to the inner and outer ends of the longitudinal side of the second opening groove 211a by a nut. The longitudinal distance of the second movable block 213 in the second opening groove 211a can be adjusted by adjusting the position of the second adjusting bolt 214 on the side of the second opening groove 211a.

[0037] The upper surface of the second moving block 213 is provided with a third opening groove 213a. The third opening groove 213a is arranged horizontally, and several third opening grooves 213a are arranged side by side. The structure of the third opening groove 213a is adapted to the structure of the hydraulic cylinder 3.

[0038] Several hydraulic cylinders 3 on the upper surface of the first adjustment component 21 are connected in series by oil pipes, and then form a hydraulic circuit with the hydraulic pump station 4 through the oil pipes; several hydraulic cylinders 3 on the upper surface of the second adjustment component 22 are connected in series by oil pipes, and then form a hydraulic circuit with the hydraulic pump station 4 through the oil pipes.

[0039] The working principle of this utility model is as follows: Before clamping the object, firstly, adjust the relative distance between the first adjusting component 21 and the second adjusting component 22; the specific adjustment steps are as follows:

[0040] Loosen the two nuts locked on the first adjusting bolt 212, and adjust the position of the first adjusting bolt 212 on the base 23 appropriately so that the relative distance between the first adjusting component 21 and the second adjusting component 22 is adjusted, thereby ensuring that the relative distance between the hydraulic cylinder 3 on the upper surface of the first adjusting component 21 and the hydraulic cylinder 3 on the upper surface of the second adjusting component 22 can accommodate the clamped object; tighten the two nuts on the first adjusting bolt 212 so that the first adjusting component 21 and the second adjusting component 22 will not move relative to each other.

[0041] Next, adjust the clamping position of hydraulic cylinder 3 on the object being clamped. The specific adjustment steps are as follows:

[0042] Loosen the two nuts locked on the second adjusting bolt 214, and adjust the position of the first adjusting bolt 214 on the first moving block 211 appropriately, thereby changing the position of the second moving block 213 on the first moving block 211; the second moving block 213 drives the hydraulic cylinder 3 to move, so that the hydraulic cylinder 3 moves to the appropriate clamping position on the clamped object. When the hydraulic cylinder 3 is in the appropriate position, lock the two nuts on the second adjusting bolt 214 so that the hydraulic cylinder 3 no longer undergoes relative displacement.

[0043] After completing the above position adjustments, start the hydraulic pump station 4. Adjust the output pressure of the hydraulic pump station 4 appropriately using pressure gauge 41 to avoid excessive or insufficient oil pressure, which could affect the clamping effect of the hydraulic cylinders 3. Under the action of the hydraulic pump station 4, several parallel hydraulic cylinders 3 on the upper surfaces of the first adjusting assembly 21 and the second adjusting assembly 22 extend their telescopic rods, pushing the cylinder heads towards the clamping surface of the object being clamped. Since the stroke of the telescopic rod of each hydraulic cylinder 3 is independent, the position of the cylinder head of each hydraulic cylinder 3 is adapted to the surface of the object being clamped. Therefore, the shape of the clamping surface of the object being clamped determines the shape of the clamping surface formed by the parallel hydraulic cylinders 3; that is, the shape of the clamping surface formed by the parallel hydraulic cylinders 3 is variable.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
