Referring to fig. 6 to 7, fig. 6 shows a structural schematic diagram of a tool in a first embodiment of the present invention, fig. 7 shows a structural schematic diagram of a workpiece mounting structure of the tool in fig. 6, and a tool 400 provided in this embodiment includes a tool base 100 and a plurality of workpiece mounting structures 500. The specific structure of the fixture base 100 refers to the above embodiments, and since the fixture 400 of this embodiment adopts all technical solutions of all the above embodiments, all the beneficial effects brought by the technical solutions of the above embodiments are also achieved, and are not described in detail herein. The plurality of workpiece mounting structures 500 are disposed in one-to-one correspondence with the plurality of connecting assemblies 300 of the tool base 100 and detachably connected to each other, and different types of tool bases can be mounted on the different types of workpiece mounting structures 500. Because work piece mounting structure 500 demountable installation is on frock base 100, the vibrations that reducible frock base 100 caused work piece mounting structure 500 to slow down rocking of the cutter base member on the work piece mounting structure 500, prevent that the cutter base member from dropping.

In this embodiment, all the workpiece mounting structures 500 mounted on the tool base 100 are identical, however, in other embodiments, different types of workpiece mounting structures 500 may be mounted on the tool base 100, which depends on actual requirements, and further, vacuum evaporation of different tool bases may be completed on the same tool 400.

Referring to fig. 8 and 9, fig. 8 is a top view of a workpiece mounting structure of a tool in the present embodiment, fig. 9 is a state view of the workpiece mounting structure in fig. 8 when a tool base is mounted thereon, and at least two through grooves 510 are formed on an end surface of a top end of each workpiece mounting structure 500. The at least two through grooves 510 include at least one first through groove 512 disposed along the first direction O1 and at least one second through groove 514 disposed along the second direction O2, and the first direction O1 intersects the second direction O2 such that the first through groove 512 intersects the second through groove 514. The first through groove 512 and the second through groove 514 are used for alternately stacking the tool bases 502, and two ends of the tool bases 502 extend out of the side surface of the workpiece mounting structure 500.

By providing the first through-groove 512 and the second through-groove 514 intersecting each other on the end surface of the tip end of the workpiece mounting structure 500, when the tool bases 502 are mounted, the tool bases 502 can be stacked alternately in order by first placing one tool base 502 in the first through-groove 512 and then placing the other tool base 502 in the second through-groove 514. Compared with a magnetic suction mode, the tool 400 can accommodate more cutter substrates 502 in a similar space size, the mounting quantity of the cutter substrates 502 is increased, the quantity of the cutter substrates 502 subjected to single vacuum coating is increased, and the production cost of the coated cutter is reduced. In addition, because the working surfaces of the grooving tool are located at the two ends of the tool base 502, the two ends of the mounted tool base 502 can extend out of the through groove 510, i.e., the through groove 510 can not contact the two ends of the tool base 502, and the formation of coatings on the working surfaces of the grooving tool cannot be influenced between the tool bases 502 which are staggered and stacked mutually, so that the uniformity of the coatings on the working surfaces of the grooving tool is ensured, and the use performance of the grooving tool is improved.

In this embodiment, the at least two through slots 510 include a first through slot 512 and a second through slot 514, that is, the end surface of the top end of the workpiece mounting structure 500 is provided with a first through slot 512 disposed along the first direction O1 and a second through slot 514 disposed along the second direction O2.

Further, the first through groove 512 and the second through groove 514 intersect at the center of the end face of the top end of the mounting member 530, that is, the first through groove 512 and the second through groove 514 both penetrate through the center of the end face of the top end of the workpiece mounting structure 500, so that the length of the first through groove 512 in the first direction O1 and the length of the second through groove 514 in the second direction O2 are ensured, when the tool base 502 is mounted, the other parts except the two ends of the tool base 502 can be more accommodated in the through grooves 510, and the stability of the tool base 502 in the through grooves 510 is improved.

In this embodiment, the first through groove 512 and the second through groove 514 are vertically arranged, that is, the first direction O1 and the second direction O2 are vertically arranged, so that the through groove 510 is arranged in a cross shape as a whole. Where "in a vertical arrangement" is to be understood as substantially vertical or substantially vertical, this includes the case of complete vertical.

In this embodiment, the workpiece mounting structure 500 is a unitary structure and has a cylindrical or round rod shape as a whole, and includes a first cylinder 516 and a second cylinder 518 coaxially connected, and the diameter of the first cylinder 516 is larger than that of the second cylinder 518. The through slot 510 is opened at one end of the first cylinder 516 far from the second cylinder 518, and extends toward the other end of the first cylinder 516 along the axial direction. Obviously, the greater the axial depth of the through-slots 510, the greater the number of tool bodies 502 that can be placed therein, while also taking into account the structural strength of the first cylinder 516. The width of the through slot 510 depends on the size of the slot cutter. The first through groove 512 and the second through groove 514 pass through the axis of the first cylinder 516 and intersect with the axis. The material of the workpiece mounting structure 500 may be, but is not limited to, stainless steel.

It should be noted that, in other embodiments, the at least two through slots 510 further include at least a third through slot disposed along the third direction, and a third through slot passes through the axis of the first cylinder 516 and intersects the first through slot 512 and the second through slot 514 at the axis. The shape of the workpiece mounting structure 500 is not limited to a cylinder or a round rod, and may also be an elliptic cylinder, a square column, a pentagonal column, or another polygonal column, and the specific shape may be determined according to actual needs.
