Description

Technical Field

[0001] The utility model belongs to the field of clamps, and in particular relates to an assembled hydraulic vise structure. Background Art

[0002] Existing vise clamps usually use threaded rods as force-applying components, and provide clamping force to the workpiece as the threaded rod is twisted horizontally. However, the threaded rods in the vise structure are all trapezoidal threads. Due to the effect of the thread pair, they have self-locking ability, but it is difficult to obtain a large clamping force (such as greater than 200,000N). In addition, due to the influence of the jaw structure, the existing vise can only be used to clamp workpieces with a clamping surface that is a vertical plane. The clamping ability is weak for workpieces with a clamping surface that is an inclined surface, resulting in limitations in the application of the vise. Therefore, in view of the problems of limited clamping force and usage limitations of existing vise clamps, it is very practical to develop an assembled hydraulic vise structure.

[0027] In this embodiment, the hydraulic cylinder 3 replaces the original screw structure, and the incompressibility and high viscosity of the hydraulic oil are utilized to form a larger pressure with a smaller oil cylinder. The hydraulic oil is transmitted to the hydraulic cylinder 3 through the communicating vessel. Due to the area ratio of the two, a larger pressure will be generated, which is called the lifting force. By utilizing this principle, a larger clamping force can be formed, which can easily reach 20t, 30t, 50t or even higher. At the same time, a one-way valve is provided in the hydraulic cylinder 3, which has excellent air sealing performance and will not produce backflow. Therefore, once the clamping force is generated, it will not decrease and change by itself, thereby ensuring the self-locking property of the vise when working.

The present embodiment is different from the first embodiment in that the chuck assembly 7 comprises an upper wire rod 71, a lower wire rod 72, a rotating screw 74 and a rotating flange 76.

[0029] In this embodiment, the chuck assembly 7 can be used to cooperate with a variety of different clamping components 8. The clamping components 8 in this application are mainly divided into two types. One is a plate structure, and its composition is similar to that of traditional jaws, and is mainly used to clamp workpieces with flat clamping surfaces. The other is a wedge structure, which is mainly used to clamp workpieces with inclined clamping surfaces. When installing the plate clamping component, bolts are used to cooperate with the through holes on the plate clamping component and the threaded holes on the upper wire rod 71 and the lower wire rod 72 to achieve disassembly and connection. When installing the wedge clamping component, the fixed block is still installed by bolt fixing, and the adjusting wedge can be lifted and lowered by cooperating with the rotating screw 74. This arrangement makes it easy for the jaws to cooperate with the workpiece. When clamping, the component can be placed on the fixed block first, and then the adjusting wedge can be cooperated with the fixed block to ensure the fit between the clamping component and the workpiece.

[0030] Specific implementation method three: Combination Figures 1 to 8This embodiment is described. The difference between this embodiment and the second embodiment is that the clamping member 8 is a clamping plate structure, and the clamping member 8 is detachably connected to the upper wire rod 71 and the lower wire rod 72 in the chuck assembly 7 by bolts. The other components and connection methods are the same as those in the second embodiment.

[0031] Specific implementation method four: Combination Figures 1 to 8 This embodiment is described. The difference between this embodiment and the third embodiment is that the clamping surface of the clamping member 8 is uniformly processed with groove-shaped grids. The other components and connection methods are the same as those of the third embodiment.

[0032] Specific implementation method five: Combination Figures 1 to 8 This embodiment is described. The difference between this embodiment and the fourth embodiment is that a plurality of circular arc pits are evenly distributed on the clamping surface of the clamping member 8. The other components and connection methods are the same as those of the fourth embodiment.

[0033] In combination with the description of specific implementation mode fourth and specific implementation mode five, the material of the plate-type structure clamping component 8 can be prepared by aluminum alloy, copper alloy, carbon steel, etc. Such a setting can prevent the jaw guard from being too hard and damaging the workpiece. The clamping surface of the clamping component 8 is processed with multiple arc pits or groove-shaped grids to increase the friction between the clamping surface and the workpiece and provide clamping stability.

[0034] Specific implementation method six: Combination Figures 1 to 8 This embodiment is described. The difference between this embodiment and the fifth embodiment is that the clamping member 8 includes an adjusting wedge 81 and two fixed wedges 82. The adjusting wedge 81 is arranged on the upper wire rod 71 and is slidably connected to the upper wire rod 71. The two fixed wedges 82 are arranged on the lower wire rod 72 and the two fixed wedges 82 are arranged below the adjusting wedge 81. The two fixed wedges 82 are symmetrically arranged along the center line of the length direction of the adjusting wedge 81, and each fixed wedge 82 is detachably connected to the lower wire rod 72 by bolts. The other components and connection methods are the same as those of the fifth embodiment.

[0035] Specific implementation method seven: Combination Figures 1 to 8This embodiment is described. The difference between this embodiment and the sixth embodiment is that an adjusting nut 812 is provided at the center of the mounting side of the adjusting wedge block 81, and the adjusting nut 812 is fixedly connected to the adjusting wedge block 81, a guide block 811 is provided on both sides of the adjusting nut 812, and each guide block 811 is provided corresponding to a guide groove 73, each guide block 811 is fixedly connected to the adjusting wedge block 81, the adjusting nut 812 is sleeved on the rotating lead screw 74, and the adjusting nut 812 is threadedly connected to the rotating lead screw 74, each guide block 811 is correspondingly inserted in a guide groove 73, and each guide block 811 is slidably connected to the upper wire rod 71. Other components and connection methods are the same as those of the sixth embodiment.

[0036] Specific implementation method eight: Combination Figures 1 to 8 This embodiment is described. The difference between this embodiment and the seventh embodiment is that the guide groove 73 is a T-shaped groove and the guide block 811 is a T-shaped block. The other components and connection methods are the same as those of the seventh embodiment.

[0037] In combination with the description of specific embodiments six to eight, the adjusting wedge block 81 is a movable part, which can be lifted and lowered under the drive of the rotating screw 74, and is used to cooperate with the fixed block 82 to realize the inclined clamping of the workpiece. The guide block 811 on the adjusting wedge block 81 is arranged in cooperation with the guide groove 73 to ensure that the adjusting wedge block 81 can move in the vertical direction when lifting and lowering, and there will be no deviation affecting the clamping effect. The use of the T-slot and T-block cooperation method can also effectively prevent the adjusting wedge block 81 from tilting forward, and the extrusion force applied to the rotating screw 74 is too large, which affects the accuracy of the axis of the rotating screw 74. In order to increase the friction between the adjusting wedge block 81 and the fixed block 82 and the workpiece, a rubber layer can be added to the clamping surface of the adjusting wedge block 81 and the fixed block 82, or a groove grid can be processed on the clamping surface.

[0038] The present invention has been disclosed as above with preferred implementation cases, but it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent implementation cases with equivalent changes by using the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above implementation cases based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.

[0039] How it works

[0040] When the present application is used, firstly, a suitable clamping member 8 is selected according to the workpiece to be clamped. After the clamping member 8 is determined, the clamping member 8 is installed on the upper wire rod 71 and the lower wire rod 72 in the chuck assembly 7. If the clamping surface of the workpiece is a vertical plane, the clamping member 8 is a plate-shaped structure and the clamping member 8 is detachably connected to the chuck assembly 7 by bolts. If the clamping surface of the workpiece is an inclined surface (refer to Figure 1 , Fig.10 and Fig.11 ), the clamping component 8 adopts a combined wedge structure, in which the fixed block 82 is still detachably connected to the lower wire rod 72 in the chuck assembly 7 by bolts, and the adjusting wedge 81 is slidably connected to the upper wire rod 71 in the chuck assembly 7 by adjusting the nut 812 and the guide block 811. The sliding structure is set in view of the fact that the workpiece with an inclined clamping surface may be difficult to position during clamping. The movable seat 9 can be pushed to a suitable position by the hydraulic cylinder 3, and then the workpiece can be placed on the fixed block 82. After the setting is stable, the adjusting wedge 81 is moved downward to contact the workpiece. After contact, the clamping action is realized by the fine-tuning hydraulic cylinder 3. At the same time, this setting can also improve the versatility of the wedge clamping component. For workpieces with the same slope clamping surface but different sizes, the clamping range of the vise can also be expanded by adjusting the distance between the adjusting wedge 81 and the fixed block 82.
