Description

3D prints quick centre gripping frock of base plate wire-electrode cutting

Technical Field

The utility model relates to a vibration material disk technical field especially relates to a quick centre gripping frock of 3D printing substrate line cutting.

Background

Additive manufacturing (3D printing) is a manufacturing technique for building three-dimensional objects by successively fusing more than one thin layer of material. Powder bed type additive manufacturing is one of additive manufacturing technical routes, and the basic process steps are as follows: the three-dimensional model is stored in a computer, and the model is layered to obtain the section data of each layer. The powder system (device) spreads the powder material into a thin layer on the working platform, and a high-energy-density ray beam (laser or electron beam) scans a section of the three-dimensional model on the powder layer; then, the working platform descends by the thickness of one powder layer, a new layer of powder is laid on the working platform, and the next section of the three-dimensional model is scanned by rays; and repeating the steps until the three-dimensional object is manufactured.

In the 3D printing process, a large stress is generated, which causes deformation of parts in the printing process, and thus the parts need to be printed on the substrate to prevent the deformation of the parts. In this way, after the printing of the component is completed, the component needs to be separated from the substrate for the next process. In practice, a wire cutting process is often used to separate the part from the substrate. In the process of wire cutting operation, the substrate needs to be fixed on a workbench of a wire cutting machine tool, and most of the existing clamping tools are complex to operate and inconvenient to use.

Specifically, a mounting plate 2 is provided on the base 1, the top of the mounting plate 2 has a first inclined surface 3, and the bottom surface of the connecting plate 4 has a second inclined surface 5. The first bevel 3 and the second bevel 5 are configured to have a matching slope. In detail, the first inclined surface 3 is an inclined surface which is away from the working area of the wire-cut electrical discharge machine and inclined toward the base 1 side. In this way, during assembly, the connecting plate 4 can be fixed on the base plate 15, and then the connecting plate 4 is hung on the top of the mounting plate 2, so that the first inclined surface 3 is attached to the second inclined surface 5. At this time, the first inclined surface 3 supports the connecting plate 4 through the second inclined surface 5, and the connecting plate 4 is not easy to move in the transverse direction under the matching of the first inclined surface 3 and the second inclined surface 5. Meanwhile, the connecting plate 4 is not easy to move in the vertical direction under the self weight of the substrate 15, so that the substrate 15 can be clamped quickly by the tool.

And, in order to restrict the movement of the connection plate 4 in the longitudinal direction, the mounting plate 2 is opened at the top surface thereof with a mounting groove 8 communicating with both side surfaces, and the first inclined surface 3 is formed at the bottom surface of the mounting groove 8. The connecting plate 4 is configured to fit the mounting groove 8, that is, when the connecting plate 4 is inserted into the mounting groove 8 to make the first inclined surface 3 fit with the second inclined surface 5, two ends of the connecting plate 4 abut against two sidewalls of the mounting groove 8, respectively. It can be understood that under the contact between the connecting plate 4 and the mounting groove 8, the connecting plate 4 is not easy to move longitudinally, and the connecting plate 4 is not easy to be separated from the mounting plate 2 longitudinally.

Furthermore, positioning parts 9 are arranged on two side walls of the mounting groove 8, and positioning grooves 10 which are provided with corresponding side walls of the connecting plate 4 penetrate through the end face of each end of the connecting plate. And when the connecting plate 4 is clamped into the mounting groove 8, the positioning piece 9 on the same side is clamped into the positioning groove 10 on the same side. The circumferential position of the connecting plate 4 can be defined by the cooperation of the two positioning elements 9, i.e. the connecting plate 4 is not prone to tilt, i.e. the base plate 15 is not prone to tilt. Further, the accuracy of the wire cutting is improved, and the workpiece cut on the substrate 15 is less likely to occur. Preferably, a connecting hole 12 is formed on a side wall of the mounting groove 8, the positioning member 9 includes a positioning pin 13, and the positioning pin 13 is partially inserted into the connecting hole 12.

Furthermore, a preformed hole I7 penetrates through the end face of the base 1, and the base 1 can be stably and conveniently fixed on a workbench of the linear cutting machine through the preformed hole I7 by the fastening piece 14. And the lateral wall of the connecting plate 4 is provided with a second preformed hole 11 in a penetrating manner, and the fastening piece 14 can stably and conveniently fix the connecting plate 4 on the base plate 15 through the second preformed hole 11. Preferably, the fastener 14 comprises a fastening bolt.

And in order to strengthen the structural stability of the tool, at least one reinforcing plate 6 is connected between the base 1 and the mounting plate 2. Preferably, the reinforcing plates 6 are provided in two pieces and are disposed at both sides of the base 1 in an opposed manner to achieve stable support of the mounting plate 2.

Example two:

as shown in fig. 3, the difference between the second embodiment and the first embodiment is that a positioning hole 16 communicating with the side wall of the mounting groove 8 is formed through the side wall of the mounting plate 2, and a positioning rod 17 is screwed into the positioning hole 16. The positioning rod 17 is rotated so that the end of the positioning rod 17 is inserted into the mounting groove 8, a positioning block 18 is provided at the end, and elastic portions 19 are provided on both side walls of the positioning block 18.
