Description

Technical Field

[0001] The utility model belongs to the technical field of clamping tools, and in particular relates to a floating clamping tool for slender parts. Background Art

[0002] The existing clamping method for slender parts generally uses six sets of vises for clamping. Before clamping, the six sets of vises need to be calibrated and then clamped. The existing vises generally use one side of the workpiece as the processing reference. When the processing technology uses the center of the workpiece as the reference, manual operation is required for alignment, which prolongs the processing preparation time, is inconvenient to operate, and reduces production efficiency. At the same time, the positioning accuracy of the existing vises is poor, and cumulative errors will occur during the long-term assembly and processing of the workpiece, resulting in errors in the subsequent assembly and processing of the workpiece, affecting the assembly and processing accuracy of the workpiece. In addition, during use, iron filings and other foreign matter will enter from the gap of the shell, causing pollution to the screw or damaging the thread, affecting the rotation of the screw. In addition, since the guide rail is a slender workpiece, the surface parallelism cannot reach an ideal state. When clamping using this method, the parts are easy to deform, and it is difficult to align the six sets of vises at the same time. Summary of the invention

[0003] In order to solve the problem of easy deformation of slender workpieces caused by vise clamping in the prior art, the utility model provides a floating clamping fixture for slender parts, which ensures the deformation degree of the slender parts and the relative position dimensions of the parts, while also improving the processing efficiency.

[0004] The purpose of the utility model is achieved in the following ways:

[0005] A floating clamping tool for slender parts comprises a workbench, on which at least two groups of floating vises are slidably arranged, the floating vise comprising two movable jaws, a vise base plate and two vise slide blocks, the vise base plate being slidably arranged on the workbench, the vise slide block being slidably connected to the vise base plate, a movable jaw that can rotate horizontally and a side plate for limiting the movable jaw are arranged on the vise slide block, and on the vise slide block on the side of the side plate away from the jaws, the two movable jaws are clamped inwardly or withdrawn outwardly at the same time.

[0006] The movable jaw is arranged on the vise slide block through the Z-axis rotating shaft, a pressure plate is arranged on the top of the Z-axis rotating shaft, and the pressure plate is fixed on the Z-axis rotating shaft through a second bolt to limit the Z-axis displacement of the movable jaw.

[0007] A first bolt passes through the middle of the side plate, and the first bolt is threadedly connected with the vise slider.

[0008] A double-headed screw rod with opposite rotation directions is arranged between the two vise sliders. The double-headed screw rod is threadably connected with the vise sliders, and two ends of the double-headed screw rod respectively pass through the two vise sliders.

[0009] A handle is arranged at the end of the double-headed screw.

[0010] Six sets of floating vises are slidably set on the workbench.

[0011] Compared with the prior art, the utility model designs the movable jaws to rotate around the Z-axis so that the two movable jaws fit with the side surfaces of the slender workpiece, and then the two movable jaws clamp the workpiece inward at the same time, which not only ensures the relative position and size of the workpieces with each other, but also ensures the deformation degree of the slender parts, while also improving the processing efficiency and solving the problem that the slender workpiece is easily deformed during clamping.

[0017] like Figure 1 As shown, a floating clamping tool for elongated parts comprises a workbench 1, on which at least two sets of floating vises 2 are slidably arranged; Figure 2-5 As shown, the floating vise 2 includes a first movable jaw 7, a second movable jaw 8, a vise base plate 10 and two groups of vise slide blocks 11. The lower surface of the vise base plate 10 is slidably connected to the workbench 1, and the upper surface of the vise base plate 10 is slidably connected to the two groups of vise slide blocks 11. The first group of vise slide blocks are provided with a first movable jaw 7 that can be rotated horizontally and a side plate 9 for limiting the first movable jaw 7. The second group of vise slide blocks are provided with a second movable jaw 8 that can be rotated horizontally and a side plate 9 for limiting the second movable jaw 8. Both side plates 9 are away from the jaws, and the first movable jaw 7 and the second movable jaw 8 are clamped inward or withdrawn outward at the same time.

[0018] Furthermore, the first movable jaw 7 and the first movable jaw 8 are respectively arranged on the first vise slide block and the second vise slide block through the Z-axis rotation axis 12, and the first movable jaw 7 and the first movable jaw 8 rotate horizontally on the vise slide block around the Z-axis rotation axis 12 to adapt to the deformation of the slender workpiece. A pressure plate 5 is arranged on the top of the Z-axis rotation axis 12, and the pressure plate 5 is fixed to the Z-axis rotation axis by the second bolt 6 to limit the Z-axis displacement of the movable jaw.

[0019] The first bolt 4 passes through the middle of the side plate 9, and the first bolt 4 is threadedly connected to the vise slider 11. When the first bolt 4 is tightened downward, the side plate 9 is pressed and fixed to the vise slider 11; when the first bolt 4 is loosened upward, the side plate 9 rotates around the first bolt 4, and the rotation angle is the same as the angle of the first movable jaw 7 or the first movable jaw 8, which plays a limiting role on the first movable jaw 7 or the first movable jaw 8.

[0020] Furthermore, a double-headed screw 3 with opposite rotation directions is arranged between the two vise sliders 11. The double-headed screw 3 is threadedly connected to the vise sliders 11, and both ends pass through the two vise sliders 11 respectively. By rotating the double-headed screw 3, the first movable jaw 7 and the first movable jaw 8 can be clamped inward or withdrawn outward at the same time.

[0021] Furthermore, a handle is provided at the end of the double-headed screw rod 3, and the double-headed screw rod 3 can be rotated by the handle, which makes the operation more convenient.

[0022] According to a further preferred embodiment, six groups of floating vises 2 are slidably arranged on the workbench 1. The six groups of floating vises 2 are arranged on the workbench 1 to ensure that the slender workpiece is firmly clamped in the entire length direction and the force is evenly applied. In addition, the number of floating vises 2 on the workbench can be appropriately increased or decreased according to the length or aspect ratio of the slender workpiece. Since the floating vises 2 are slidably arranged on the workbench, when the number of floating vises 2 on the workbench is increased or decreased, the distance between each floating vise 2 can be adjusted to accommodate different workpieces. When the spacing between the floating vises 2 needs to be adjusted, the floating vise 2 slides on the workbench 1, and when clamping the workpiece, the floating vise 2 is fixedly connected to the workbench 1 by bolts or other fixing methods.

[0023] Working process: Before clamping, loosen the first bolt 4 on the side plate 9 upwards, and withdraw the first movable jaws 7 and 8 outwards to ensure that the slender workpiece can be easily placed in the jaws. When placing the workpiece, place the workpiece in the two sets of floating vises 2 in the middle of the workbench 1. When the slender workpiece is placed in the jaws of the floating vise 2, adjust the distance between the first movable jaws 7 and 8, and rotate them horizontally around the Z-axis 12 to adapt to the deformation of the workpiece, so that the first movable jaws 7 and 8 are fully aligned with the side of the part, then the first movable jaws 7 and 8 are adjusted in place, and the first bolt 4 on the side plate 9 is tightened downwards, so that the side plate 9 is close to the vise slider 11 and fixed thereto to limit the horizontal rotation of the first movable jaws 7 and 8. Adjust the remaining sets of floating vises 2 in the same way, and then further operations can be performed.

[0024] The utility model designs the movable jaws to rotate around the Z-axis so that the two movable jaws are fitted with the side surfaces of the slender workpiece, and then the two movable jaws clamp the workpiece inwards at the same time, which not only ensures the relative position dimensions of the workpieces, but also ensures the deformation degree of the slender parts, while also improving the processing efficiency and solving the problem that the slender workpiece is easily deformed during clamping.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
