The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1 to 9, the jig of the present embodiment is used for fixing a workpiece 8, and mainly includes a base 1, a main body 2, two pushing mechanisms, and two height positioning plates 31 and 32.

As shown in fig. 1 and 2, the base 1 is plate-shaped, and has a plurality of first positioning holes 11 and fixing holes 12.

As shown in fig. 1 and 3, the main body 2 is substantially L-shaped and includes two halves vertically connected to each other. The inner sides of the two half parts are respectively provided with a first plane 21 and a second plane 22 which are vertical to each other. The first plane 21 and the second plane 22 are used as reference planes for the position of the workpiece 8, and the intersecting line corresponds to a good zero point start position in the CNC machining program. The upper part of each half part is provided with a sunken part 23, and the bottom of the sunken part 23 is provided with a through second positioning hole 24 downwards. The second positioning hole 24 corresponds to the first positioning hole 11 of the base to be positioned by insertion of a positioning pin (not shown). The outer end of each half part is provided with three first screw holes 25 inwards, and the bottom surface is provided with a second screw hole 26 upwards. The second screw holes 26 correspond to the fixing holes 12 of the base 1 to fix the base 1 and the body 2 by screws (not shown) screwed to the second screw holes 26 through the fixing holes 12. One half is also provided with two insertion holes 27 which transversely penetrate in the vertical direction for inserting the height positioning plates 31, 32.

The two pushing mechanisms are respectively arranged opposite to the first plane and the second plane and used for pushing the workpiece 8 from two directions respectively so that the workpiece 8 is abutted against the first plane and the second plane to position and fix the workpiece 8.

In this embodiment, each pushing mechanism includes a guide 4, a pushing member 5, and a driving mechanism 6. As shown in fig. 4, the guide member 4 is in the form of a bar, and has a guide hole 41 with a square cross section for the pushing member to pass through, and is placed in the recess 23 of the main body when assembled. As shown in fig. 5, the pushing member 5 is also in the form of a bar having a smaller cross-sectional dimension than the guide member 4, and has a recess 51 at one end. During assembly, the pushing member 5 passes through the guiding hole 41, the front end of the pushing member faces the first plane 21 or the second plane 22, and the rear end of the pushing member is pushed by the driving mechanism 6 to move towards the first plane 21 or the second plane 22 so as to realize that the pushing mechanism pushes the workpiece 8.

In this embodiment, the driving mechanism 6 includes a fixing member 61, a bolt 62, and a limiting member 63. As shown in fig. 6, the fixing member 61 is strip-shaped and has a groove 611 perpendicular to the pushing member 5 and an elongated through hole 612 transversely communicating with the groove 611. The fixing member 61 is further provided with a plurality of fixing through holes 613 corresponding to the first screw holes 25 of the main body 2, so that the fixing member 61 is fixed on the main body 2 by passing screws through and screwing the screws into the first screw holes 25. As shown in fig. 7, the limiting member 63 is oblong and has a width equal to that of the groove 611, so that the limiting member 63 can be inserted into the groove 611 and cannot rotate. The middle part of the limiting member 63 is provided with a threaded hole 631 matched with the bolt 62. The bolt 62 is a socket head cap screw to facilitate insertion of a socket head cap screw for rotation. When assembling, the limiting member 63 is embedded in the groove 611, the bolt 62 passes through the through hole 612, is screwed to the threaded hole 631, and the end thereof is inserted into the recess 51 to abut against the pushing member 5.

As shown in fig. 8 and 9, the height positioning plates 31 and 32 can be inserted into the insertion holes 27 for holding the workpiece 8. In this embodiment, the supporting surfaces 311, 312 of the two height positioning plates 31, 32 have different heights, which are used to provide a plurality of different supporting heights. For example, in this embodiment, the number of the insertion holes is two, and the number of the height positioning plates is also two, so that four different supporting heights can be provided to meet the requirements of workpieces with different heights. Of course, in other embodiments, the number of the insertion holes and the height positioning plates can be adjusted according to requirements. In addition, the supporting device can be supported by the base without arranging a height positioning plate, or suspended and clamped with the main body by the pushing mechanism. But the height positioning plate is used for supporting so that the workpiece can be more conveniently installed, and the workpiece can be accurately positioned in the vertical direction.

After assembly and machining, a workpiece 8 is placed on one of the height positioning plates 3, then the two bolts 62 are rotated to push the pushing member 5 from two directions respectively, so that the workpiece 8 abuts against the first plane 21 and the second plane 22, the workpiece 8 is positioned by the upper surface of the height positioning plate 3 and the first surface 21 and the second surface 22 of the main body 2, and the pushing mechanism and the main body 2 are used for clamping and fixing the workpiece 8.

The zero starting position is set for the first time only during processing of the jig, CNC processing parameters are input, direct processing can be achieved, convenience, rapidness, time saving and labor saving are achieved, batch consistency and precision high perpendicularity of small workpieces to be processed can be guaranteed to be 0.005mm, and flatness can be guaranteed to be 0.002mm. The whole jig is not required to be replaced, so that the clamp and labor hour cost are reduced. The main body ensures the required processing precision, and the workpiece can be quickly clamped by the pushing mechanism after being put into the main body. The clamping is performed from two vertical directions, so that the applicability is strong, and the clamp is suitable for small workpieces.
