DETAILED DESCRIPTION

The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

As shown in Figures 1 and 2, they are schematic diagrams of the structure of a fixture capable of stably clamping a workpiece provided by the utility model. The fixture capable of stably clamping a workpiece includes a base 10, at least one pair of inner support components 20 arranged on the top of the base 10, at least one main positioning portion 30 arranged on the top of the base 10 and used to limit the movement of the workpiece in one direction on the horizontal plane, and at least one auxiliary positioning portion 40 arranged on the top of the base 10 and used to limit the movement of the workpiece in another direction on the horizontal plane. The fixture capable of stably clamping a workpiece also includes some other functional modules, such as those arranged on, etc., which should be technologies well known to those skilled in the art and will not be described in detail one by one here.

It should be noted that the structure of the workpiece matched with the clamp includes a panel and a baffle disposed around one side of the panel. When clamping, the side of the workpiece with the baffle needs to face the bottom plate 10, and the panel of the workpiece is abutted against the top of the first mounting seat 21 of the inner support assembly 20 described below.

The base 10 is rectangular. At least one hanging ring 11 is provided on the top of the base 10. The hanging ring 11 is threadedly mounted on the base 10. In this embodiment, there are four hanging rings 11, which are respectively located at the four corners of the base 10. A rope is connected to each of the hanging rings 11, so that the base 10 can be lifted horizontally, thereby facilitating the handling of the clamp.

The inner support assembly 20 includes a first mounting seat 21 and a driving cylinder 22 horizontally inserted on the side wall of the first mounting seat 21 .

The tops of the first mounting seats 21 are respectively arranged horizontally and at the same height, so that when a workpiece is placed on the top of the first mounting seats 21 , the workpiece can remain horizontal.

In this embodiment, the number of the inner support components 20 is two pairs, so that it can not only provide a stable support effect, but also stably perform preliminary positioning of the workpiece in the horizontal direction. Each pair of the inner support components 20 is arranged at an interval.

The main positioning part 30 includes a main clamping body 31 and an abutting body 32 arranged corresponding to the main clamping body 31. In this embodiment, there are two main positioning parts 30, and the two main positioning parts 30 are arranged at an interval.

All the main clamps 31 are respectively arranged at one end of the base 10, and all the abutting bodies 32 are respectively arranged at the other end of the base 10. Two main clamps 31 are arranged at intervals, and two abutting bodies 32 are arranged at intervals. Each main clamp 31 is respectively arranged opposite to one abutting member 32, so that they can abut against the opposite side walls of the workpiece when in use.

The main clamp body 31 includes a second mounting seat 311 disposed on the top of the base 10 , and a main positioning bolt 312 inserted into the side wall of the second mounting seat 311 .

The abutting body 32 includes a third mounting seat 321 disposed on the top of the base 10, and an abutting top portion 322 disposed on the side of the third mounting seat 321. The abutting top portion 322 is conical, and the axis of the cone is parallel to the axis of the main positioning bolt 312. The end of the abutting top portion 322 faces the main clamping body 31.

The auxiliary positioning portion 40 includes a fourth mounting seat 41 disposed on the top of the base 10 , and an auxiliary positioning bolt 42 inserted into a side wall of the fourth mounting seat 41 .

The height of the auxiliary positioning bolt 42 is different from that of the main positioning bolt 312 , so that the heights of the abutment points of the fixture and the workpiece are different, so that the workpiece is subjected to a more uniform force. In this embodiment, the height of the auxiliary positioning bolt 42 is higher than that of the main positioning bolt 312 .

The ends of the main positioning bolt 312 and the auxiliary positioning bolt 42 are respectively provided with positioning chamfers, so as to reduce the contact area between the main positioning bolt 312 and the auxiliary positioning bolt 42, thereby ensuring the contact area between the main positioning bolt 312 and the auxiliary positioning bolt 42, and increasing the pressure to increase the friction force to ensure the stability of the fixture installation.

It should be noted that the end face of the auxiliary positioning bolt 42 of the auxiliary positioning portion 40 is always spaced from the end face of the driving cylinder 22, thereby ensuring that a gap is reserved between the auxiliary positioning portion 40 and the driving cylinder 22 for inserting a baffle of the workpiece.

When in use, firstly, the workpiece is buckled and mounted on the top of the inner support assembly 20, and the baffles of the workpiece are respectively placed in the space surrounded by the main positioning portion 30 and the auxiliary positioning portion 40. Then, the main positioning bolt 312 and the auxiliary positioning bolt 42 are tightened in sequence. During the tightening process, the position of the workpiece needs to be adjusted, so that after the main positioning bolt 312 is tightened, the two ends of the workpiece are respectively abutted against the end of the main positioning bolt 312 and the abutting top portion 322 of the abutting body 32, and the other two ends of the workpiece are abutted against the two opposite auxiliary positioning bolts 42, thereby achieving positioning.

Compared with the prior art, the fixture capable of stably clamping a workpiece provided by the utility model can limit the movement of the workpiece in two mutually perpendicular directions respectively by setting the main positioning portion 30 and the auxiliary positioning portion 40, and the inner support assembly 20 is provided to position the height of the workpiece, and each of the inner support assemblies 20 includes a driving cylinder 22, and the corresponding two driving cylinders 22 are controlled to move back and forth at the same time, so that they can respectively abut against the inner side of the baffle of the workpiece, thereby positioning the workpiece, and since the paired driving cylinders 22 are driven simultaneously, it can be ensured that the position of the workpiece after each positioning is symmetrical along the symmetry line of the corresponding two inner support assemblies 20, thereby making the position of the workpiece stable after clamping.

The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
