As shown in fig. 1 to 4, in the present embodiment, the detachable workpiece positioning mechanism 100 is used to detachably attach a workpiece 200 to be processed. The detachable workpiece positioning mechanism 100 includes: a workpiece pedestal 10, a process plate 20, and a plurality of positioning assemblies 30.
As shown in fig. 1, 3 and 4, the workpiece base 10 is composed of a base body 11 and four positioning posts 12, which are fixedly connected with each other.
The base body 11 has a rectangular plate shape with a predetermined thickness, and as shown in fig. 4, the base body 11 is fixedly connected to the workpiece 200 by a screw 210.
The four positioning columns 12 are fixedly connected with the base body 11. In the present embodiment, the four positioning pillars 12 have the same structure and function, and only one of the positioning pillars 12 is described in detail herein, and the detailed description of the other three positioning pillars 12 is omitted.
The positioning column 12 is a column with a square cross section, a positioning groove 13 is arranged on the side wall of a preset position at one end of the positioning column 12 far away from the base body 11, and the positioning groove 13 is arranged around the positioning column 12 in a circle in the axial direction.
The process plate 20 is composed of a process bottom plate 21 and a process cover plate 22 which are fixedly connected with each other.
As shown in fig. 2, 3 and 4, four receiving cavities 23 are formed between the process base plate 21 and the process cover plate 22. In the present embodiment, the four accommodating chambers 23 have the same structure and function, only one of the four accommodating chambers 23 will be described in detail, and the detailed description of the other three accommodating chambers 23 will be omitted.
The housing chamber 23 has a cross shape with a transverse slot 24 and a longitudinal slot 25 communicating with each other.
The transverse grooves 24 are perpendicular to the axial direction of the positioning posts 12, the longitudinal grooves 25 are parallel to the axial direction of the positioning posts 12, and the longitudinal grooves 25 penetrate the process cover plate 22 and extend to a certain depth towards the process base plate 21.
As shown in fig. 2 and 3, a plurality of positioning assemblies 30 are disposed in the accommodating chamber 23 for detachably fixing the positioning posts 12. In the present embodiment, the number of the positioning assemblies 30 is eight, and two positioning posts 12 are respectively arranged in the four accommodating cavities 23 and are respectively used for fixing the four positioning posts 12. Here, the eight positioning assemblies 30 have the same structure and function, and only one of the positioning assemblies 30 is explained in detail, and the detailed description of the other seven positioning assemblies 30 is omitted.
Each positioning member 30 includes a resilient member 31 of a predetermined length and a collet 32.
One end of the elastic piece 31 is fixedly connected with the end part of the transverse groove 24, the other end is fixedly connected with the clamping head 32, and the surface of the clamping head 32 facing the longitudinal groove 25 is in an arc shape, so that the clamping head 32 is conveniently embedded with the positioning groove 13. In the present embodiment, the elastic member 31 is a spring, and in the initial state, the spring is in a stretched state, and the clip 32 is fixed on one side of the transverse groove 24 by the spring and is ensured to slightly extend into the longitudinal groove 25.
Two positioning elements 30 are arranged in the same receiving chamber 23, so that one positioning element 30 is arranged on each side of the transverse groove 24 on the longitudinal groove 25, i.e. the corresponding clamp 32 is fixed by the elastic element 31. In the same accommodation chamber 23, both the fixed chucks 32 extend into the longitudinal groove 25 by a predetermined length, that is, the two chucks 32 are in a state of being close to each other.
Thus, when the positioning column 12 is inserted into the longitudinal groove 25, the two chucks 32 are pushed, and the corresponding two elastic members 31 are further pressed until the chucks are clamped into the corresponding positioning grooves 13 of the positioning column 12, so that the positioning column 12 is fixed under the elastic pressing action of the elastic members 31. After the four positioning columns 12 are all fixed, the workpiece base 10 can be fixed, and the workpiece 200 can be fixed.
When the process plate 20 needs to be replaced, the positioning column 12 is pulled out, so that the workpiece base 10 and the workpiece 200 can be pulled out together. In the process of pulling out, the positioning column 12 firstly pushes the chuck 32 towards two sides, so as to compress the elastic member 31, and when the chuck 32 is pulled out from the positioning groove 13, the elastic member 31 restores to the stretching state.
The technical scheme of the embodiment can realize the rapid switching of the workpiece 200 among all the process plates 20.
