The z-direction positioning of the workpiece usually uses equal-height blocks, and equal-height blocks with different heights are required according to the thickness of the workpiece; the x-direction positioning (i.e., the direction perpendicular to the running direction of the clamping plate of the bench vice) requires clamping a temporary positioning block or other positioning tooling on the workbench, and it needs to be disassembled and assembled for positioning according to the length of the workpiece.

[0003] Therefore, according to the different heights and lengths of the workpieces, different equal-height blocks are required for positioning. If they are too high, it is easy to interfere with the processing; and in the positioning of the two axes, a separate placement fixture is required for the workpiece to perform x-direction positioning, the operation is relatively cumbersome, and there is also limited space on the workbench.

Detailed embodiments

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments of the present utility model and the corresponding accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] The following will, with reference to the accompanying drawings, detail the technical solutions provided by the embodiments of the present utility model.

[0026] Refer to Figures 1 to 6As shown in the figure, an embodiment of the present utility model provides an adjustable device for jaw positioning, which includes a base 1, clamping plates, a distance adjustment component 4, a carrier plate 5, a height adjustment component 6, a connecting piece 7, a locking piece 8 and a positioning piece 9. The base 1 is used to support the entire device, and the carrier plate 5 is used to support or place the workpiece to be positioned.

[0027] As Figure 1 , Figure 3 and Figure 4 shown, there are two clamping plates, namely a fixed clamping plate 2 and a movable clamping plate 3 respectively. The fixed clamping plate 2 is fixedly installed on the base 1, and the movable clamping plate 3 is located on one side of the fixed clamping plate 2. The distance adjustment component 4 is arranged on the base 1 and is used to drive the movable clamping plate 3 to move so as to adjust the lateral distance between the two clamping plates.

[0028] In some practical applications, as Figure 1 and Figure 6 shown, the distance adjustment component 4 includes a slider 41 and a screw rod distance adjustment module 42. The slider 41 is slidably connected to the base 1, the movable clamping plate 3 is fixedly installed on the slider 41, and the screw rod distance adjustment module 42 is arranged on the base 1 to drive the slider 41 to move, so that the movable clamping plate 3 approaches or moves away from the fixed clamping plate 2, thereby realizing the adjustment of the distance between the two clamping plates, so as to clamp the workpiece to be positioned by the two clamping plates. The screw rod distance adjustment module 42 is a prior art, and the structure and principle formed by the cooperation of the screw rod distance adjustment module 42, the slider 41 and the two clamping plates can refer to the structure of a bench vice in the prior art.

[0029] The carrier plate 5 is horizontally arranged between the two clamping plates, and the height of the carrier plate 5 is adjusted by the height adjustment component 6. In some practical applications, as Figure 1 , Figure 3 and Figure 4 shown, the height adjustment component 6 includes at least two cross beams 61. At least two cross beams 61 are arranged at the same height between the two clamping plates (two cross beams 61 are used in actual use). At the installation position of each cross beam 61 on the fixed clamping plate 2, there are a plurality of first through slots 21 longitudinally distributed and inserted and matched with the cross beam 61. At the installation position of each cross beam 61 on the movable clamping plate 3, there are a plurality of second through slots 31 longitudinally distributed and inserted and matched with the cross beam 61. A plurality of first through slots 21 and a plurality of second through slots 31 correspond one by one to form a plurality of installation positions of the cross beam 61. The carrier plate 5 is placed on the upper ends of a plurality of cross beams 61. By inserting the cross beam 61 into the first through slots 21 and the second through slots 31 at different heights, the height adjustment of the carrier plate 5 can be realized.

[0030] It should be noted that there are also multiple carrier plates 5, and they have different sizes. The carrier plates 5 are directly placed on the upper end of the cross beam 61 and can be removed at any time. When processing workpieces of different sizes, it is necessary to replace the carrier plates 5 with appropriate sizes to ensure that the carrier plates 5 can stably carry the workpieces while avoiding the carrier plates 5 from affecting the clamping of the workpieces by the two clamping plates (that is, the distance between the two clamping plates after clamping the workpiece should be greater than or equal to the width or length of the corresponding carrier plate 5, so that the carrier plate 5 is still between the two clamping plates).

[0031] As Figures 2 to 5 shown, the connecting piece 7 is installed on one of the clamping plates through the locking piece 8 and has several installation points on this clamping plate, so that the connecting piece 7 can be at different heights on this clamping plate. In some practical applications, a slot 32 that extends longitudinally and penetrates the body of the movable clamping plate 3 in its thickness direction is provided on the movable clamping plate 3. The overall shape of the connecting piece 7 is rectangular, and at least part of the connecting piece 7 is located in the slot 32 and can move in the slot 32 to adjust its height.

[0032] In some preferred embodiments, as Figures 3 to 5 shown, the locking piece 8 includes two second locking bolts. A number of longitudinally distributed second threaded holes 33 are provided on one side of the movable clamping plate 3, and each second threaded hole 33 extends into the slot 32. The connecting piece 7 is fixed by installing the second locking bolts in the corresponding second threaded holes 33 and pressing against the surface of the connecting piece 7. The two second locking bolts press the connecting piece 7 at the same time, ensuring the stability of the connecting piece 7. The multiple second threaded holes 33 correspond to different installation points of the connecting piece. When it is necessary to change the height of the connecting piece 7, the connecting piece can be pressed and fixed by passing the second locking bolts through the second threaded holes at the corresponding installation points.

[0033] As Figure 1 、 Figure 3 and Figure 5 shown, a positioning piece 9 that can move horizontally and is located between the two clamping plates is installed on the connecting piece 7. The moving direction of the positioning piece 9 is perpendicular to the moving direction of the movable clamping plate 3; the height adjustment of the connecting piece 7 is mainly to ensure that the height of the positioning piece 9 can always be adapted to the height of the workpiece to be positioned, so as to ensure that the positioning piece 9 can effectively limit and position the workpiece to be processed through the movement of the positioning piece 9.

[0034] In some practical applications, the positioning member 9 is configured as a pin, which is inserted into the through hole 71 on the connecting member 7. The connecting member 7 is also provided with a first threaded hole 72 connected to the through hole 71. The pin is threadedly connected to the first threaded hole 72 through a first locking bolt 73 and locked to achieve fixation. According to the size of the workpiece, the length of the pin can be appropriately changed and the pin can be moved in the through hole 71, so as to achieve the effect of positioning workpieces of different sizes.

[0035] In actual use, the height and overhang of the beam can be adjusted by the staff according to the size of the workpiece to be positioned, thereby changing the height of the carrier plate 5, and then achieving the height positioning of the workpiece, that is, positioning the workpiece in the Z-axis direction, adjusting the height of the connecting member 7 and the extension length of the positioning member 9, and then coordinating the positioning of the workpiece with the two clamps, thereby achieving the positioning of the workpiece in various directions in the horizontal direction, that is, positioning the workpiece in the X and Y axis directions. When processing batch parts, the three coordinates of the workpiece can be positioned through this adjustable device. Compared with the traditional method of using a bench vise, there is no need to add positioning tooling in other directions, thereby replacing the external positioning structure required by the original bench vise, and completing the processing plan of batch parts after one-time positioning, making the early clamping and positioning work easier and releasing the limited space of the workbench.

[0036] In addition, the adjustable device can adjust the positioning position in three coordinate directions for workpieces of different batches or sizes, so that it is suitable for clamping workpieces of various sizes, improving processing efficiency and eliminating the cumbersome process of frequently replacing different positioning tooling when processing workpieces of different sizes.

[0037] In some practical applications, at least one jack 11 (such as Figure 1 and Figure 3 ), the execution end of the jack 11 is against the lower end of the carrier plate 5. Through the arrangement of the jack 11, the carrier plate 5 can be stably supported in cooperation with the two cross beams 61.

[0038] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
