Description

Technical Field

[0001] The utility model relates to the technical field of vises, and specifically relates to a bench vise for processing aluminum tubes. Background Art

[0002] Bench vise is an essential tool for fitter, and also the origin of the name of fitter, because most of the fitter's work is done on the bench vise, such as sawing, filing, chiseling, as well as assembly and disassembly of parts. It is installed on the bench table to clamp the workpiece for processing. It is an essential tool in the bench workshop.

[0003] Existing bench vises, such as the patented pipe bench vise, announcement number: CN214769491U, adopt a mouth-shaped closed frame structure. When clamping a steel pipe, the bench vise needs to be fixed on a workbench, and the clamping direction of the bench vise is also fixed. When this type of bench vise faces aluminum pipe workpieces of different lengths and shapes (such as bent pipes or assembled pipes) and especially heavy aluminum pipe workpieces, one method is to re-fix the bench vise so that the clamping direction is aligned with the workpiece, and the other method is to adjust the aluminum pipe workpiece according to the clamping direction of the bench vise before clamping. Both methods make the processing of the aluminum pipe workpiece time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0022] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0023] Specific embodiment 1: Please refer to Figure 1-4 A bench vise for processing aluminum tubes, comprising: a base plate 1, a support arm 2, a mounting seat 3, an adjusting screw 4, an upper clamp 5, a lower clamp 6 and a handle 7. The mounting seat 3 is fixed to the upper side of the base plate 1 through the supporting arm 2, the lower part of the adjusting screw 4 is longitudinally arranged on the upper part of the mounting seat 3, the upper clamp 5 is arranged at the lower part of the mounting seat 3, and the lower end of the adjusting screw 4 is connected to the upper end of the upper clamp 5, the lower clamp 6 is arranged on the base plate 1 and its position corresponds to that of the upper clamp 5, the handle 7 is arranged at the upper end of the adjusting screw 4, and rotating the handle 7 can make the adjusting screw 4 drive the upper clamp 5 to approach or move away from the lower clamp 6 to achieve the purpose of clamping or releasing.

[0024] A placement groove 11 is provided on the upper part of the substrate 1, and a longitudinal positioning hole 12 is provided on the bottom wall of the placement groove 11; in the present embodiment, the placement groove 11 is a cross groove; when in use, the placement groove 11 is used to install the lower clamp 6, specifically, the lower clamp 6 is composed of a lower clamp block 61 and a positioning pin 62, and the upper end of the positioning pin 62 is fixedly connected to the lower end of the lower clamp block 61; a V-shaped groove is provided on the upper end of the lower clamp block 61, and teeth with anti-slip function are also provided in the V-shaped groove; the lower clamp block 61 is placed in the placement groove 11 in the form of inserting the positioning pin 62 into the positioning hole 12, and since the placement groove 11 is a cross groove, the lower clamp block 61 can be adjusted in two directions in the placement groove 11, that is, the length direction of the lower clamp block 61 can be consistent with the length direction of the substrate 1 or the width direction of the substrate 1, and the final effect is that the V-shaped groove can be reversed by 90° on the upper side of the substrate 1, thereby increasing the clamping direction of the bench vise, making the clamping of the aluminum tube more convenient and flexible. It should also be noted that the bottom wall of the positioning pin 62 is not lower than the bottom wall of the substrate 1 .

[0025] The mounting seat 3 is a box-shaped structure, and a receiving cavity 31 with an open lower end is provided inside the mounting seat 3. In addition, a pressure relief hole 32 communicating with the receiving cavity 31 is provided on the outer periphery of the mounting seat 3. The pressure relief hole 32 is located at the upper part of the mounting seat 3 body.

[0026] The upper clamping member 5 includes an upper clamping block 51 and a connecting block 52, the connecting block 52 is slidably arranged in the accommodating cavity 31 and the lower part of the connecting block 52 is at least partially located on the lower side of the mounting seat 3, the lower part of the adjusting screw 4 extends longitudinally to the accommodating cavity 31 and is rotatably connected to the upper end of the connecting block 52, and the adjusting screw 4 is threadedly connected to the upper part of the mounting seat 3; the lower end of the connecting block 52 is threadedly connected to the upper end of the upper clamping block 51, and the upper clamping block 51 can rotate circumferentially relative to the connecting block 52, and the lower end of the upper clamping block 51 is also provided with a V-shaped groove, and the V-shaped groove of the upper clamping block 51 is also provided with teeth with an anti-slip function.

[0027] In one embodiment, the upper clamping block 51 can be rotatably connected to the connecting block 52. Like the threaded connection, the V-groove of the upper clamping block 51 can be adjusted according to the direction of the V-groove of the lower clamping block 61 to better clamp the aluminum tube workpiece.

[0028] Through the technical solution, a placement groove for placing the lower clamping block is opened on the base plate, and the lower clamping block can change its direction in the placement groove. By setting the upper clamping piece into an upper clamping block and a connecting block, the upper clamping block is connected to the adjusting screw through the connecting block, and the upper clamping block and the connecting block are movably connected, so that the upper clamping block can change the direction of its own V-groove according to the placement of the lower clamping block, thereby realizing clamping in different directions. When facing workpieces of different shapes, there is no need to readjust the base plate, and only fine-tuning on the chuck can meet the clamping needs, thereby improving the convenience and flexibility of the bench vise, and ultimately improving the efficiency of aluminum tube processing.

[0029] Example 2: Please refer to Figure 5 The difference from the first embodiment is that the placement groove 11 is a circular groove, the positioning hole 12 is coaxial with the placement groove 11, and the inner diameter of the placement groove 11 is greater than the length of the diagonal angle of the cross section of the lower clamping block 61. The lower clamping block 61 can rotate circumferentially about the axis of the positioning hole 12 in the placement groove 11. By changing the size and shape of the placement groove 11, the placement direction of the lower clamping block 61 is no longer limited to two directions, but the lower clamping block 61 can be adjusted in any direction in the placement groove 11, which greatly increases the clamping direction of the bench vise and further improves the convenience and flexibility of the bench vise.
