[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Embodiment 1

[0019] As Figures 1-4As shown, the utility model provides a technical scheme: a machining center auxiliary tooling fixture, including installation fixed plate 1, installation fixed plate 1 is welded fixed on machining center, provides an installation platform for the installation of fixture body 3 in machining center, and the upper surface of installation fixed plate 1 is placed with fixture body 3, and fixture body 3 plays the clamping fixed action of the workpiece needing to be processed in machining center, and the both sides of installation fixed plate 1 surface are equipped with sliding groove 4, sliding block 5 is connected in the sliding groove 4, and the stability of the linear movement of movable extrusion plate 6 on installation fixed plate 1 is improved under the help of sliding groove 4 and sliding block 5, one side surface of sliding block 5 is fixedly connected with movable extrusion plate 6, both sides of the installation fixed plate 1 are rotatably connected with screw rod 7, movable extrusion plate 6 is moved towards fixture body 3 placed on installation fixed plate 1 by rotating screw rod 7, then let two movable extrusion plates 6 move to the both sides of fixture body 3 and clamp it, and the front and rear movement of fixture body 3 on installation fixed plate 1 is limited, one side surface of movable extrusion plate 6 is fixedly connected with limiting block 9, and limiting block 9 is engaged with the side surface of fixture body 3, when two movable extrusion plates 6 clamp fixture body 3, limiting block 9 is also connected with fixture body 3, and the left and right and up and down movement of fixture body 3 on installation fixed plate 1 is limited under the help of limiting block 9, guarantee the stability of fixture body 3 on installation fixed plate 1 installation.

[0020] Example 2

[0021] As Figures 1-4 shown, the upper surface of installation fixed plate 1 is fixedly connected with positioning block 2, and positioning block 2 is engaged with the bottom of fixture body 3, and the placement position of fixture body 3 on installation fixed plate 1 is positioned under the help of positioning block 2, to ensure that limiting block 9 can be smoothly engaged with the side hole of fixture body 3, one end of screw rod 7 is fixedly connected with twist disc 8, and screw rod 7 is conveniently rotated under the help of twist disc 8, the surface of movable extrusion plate 6 is fixedly connected with connecting rod 10 on one side of screw rod 7, and penetrating plate 11 is slidably connected on the surface of connecting rod 10, and penetrating plate 11 is engaged with twist disc 8, when the rotation of screw rod 7 is controlled by twist disc 8, penetrating plate 11 on connecting rod 10 is slid towards twist disc 8, so that penetrating plate 11 is engaged with twist disc 8, and twist disc 8 is locked, so that it cannot rotate, effectively avoiding the situation that movable extrusion plate 6 and limiting block 9 move due to the accidental rotation of twist disc 8 driving screw rod 7, causing fixture body 3 to be loose on installation fixed plate 1.

[0022] Working principle:

[0023] As Figures 1-4As shown, when the clamp body 3 needs to be disassembled and replaced due to long-term use and serious wear, the user first pushes the insertion plate 11 on the connecting rod 10 to move, so that the insertion plate 11 is disengaged from the clamping of the torsion disc 8, and the torsion disc 8 can be re-rotated. After manually twisting the torsion disc 8, the lead screw 7 is rotated, the rotation of the lead screw 7 drives the movable extrusion plate 6 and the sliding block 5 to move linearly along the sliding groove 4, so that the movable extrusion plate 6 is disengaged from the clamping of the clamp body 3 and the limiting block 9 is disengaged from the connection of the clamp body 3. In this way, the limiting of the clamp body 3 on the mounting fixed plate 1 is completely released, at this time the clamp body 3 can be pulled out from the mounting fixed plate 1, so that it is disconnected with the positioning block 2, and the disassembly operation of the clamp body 3 on the mounting fixed plate 1 is completed. After that, the new clamp body 3 is operated in reverse according to the above steps, and the replacement and installation operation of the new clamp body 3 on the mounting fixed plate 1 is completed.
