[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. Figures 1-4 The embodiments of the present application are further described in detail.

[0027] Embodiment 1

[0028] Please refer to Figures 1-4 The present embodiment provides a technical solution: a workpiece positioning device for furniture machining center, comprising: a workbench 1, an air cylinder 2, a fixed block 3, a positioning assembly 4 and a fixing assembly 5.

[0029] The main body of the workpiece positioning device is composed of a workbench 1, air cylinders 2 fixed around the workbench 1, and fixed blocks 3 arranged on the output ends of the air cylinders 2. Seven horizontal through holes are arranged on the fixed blocks 3, and vertical through holes are connected to the top of the horizontal through holes of the fixed blocks 3. The above is prior art, and the following will not be described in detail.

[0030] The positioning assembly 4 is arranged in the horizontal through hole of the fixing block 3, the positioning assembly 4 comprises a positioning block 401 slidably connected in the horizontal through hole of the fixing block 3, one end of the positioning block 401 is provided with a through hole, the other end of the positioning block 401 is provided with an elastic block, a guide rod 402 is arranged above the outer wall of the horizontal through hole of the fixing block 3, the guide rod 402 is arranged in the through hole of the positioning block 401, a spring 403 is arranged on the guide rod 402, and the fixing assembly 5 is arranged on the top of the fixing block 3.

[0031] The furniture is placed above the workbench 1, and then the fixing block 3 on the output end of the air cylinder 2 is started to drive the fixing block 3 to displace through the air cylinder 2, at this time the fixing block 3 drives the positioning assembly 4 to contact the furniture, and when the positioning assembly 4 is attached to the surface of the furniture, the fixing assembly 5 plays an effective fixing effect, thereby maintaining the stability of the furniture during subsequent processing.

[0032] During the movement of the fixing block 3, the positioning block 401 on the fixing block 3 is in contact with the furniture, thereby changing the position in the fixing block 3, at this time a plurality of positioning blocks 401 can be extruded by the spring 403 outside the guide rod 402, so that the positioning block 401 can be stably attached to the surface of the furniture.

[0033] Embodiment 2

[0034] Please refer to Figures 1-4 The embodiment provides a technical scheme: a workpiece positioning device for furniture machining center, comprising: a fixing plate 501, a threaded rod 502, a rotating handle 503, a first connecting block 504, a second connecting block 505 and a positioning plate 506.

[0035] The fixing assembly 5 comprises a fixing plate 501 fixedly arranged on the top of the fixing block 3, a threaded hole is formed in the center of the fixing plate 501, a threaded rod 502 is threadedly connected in the threaded hole of the fixing plate 501, and the fixing assembly 5 further comprises a rotating handle 503 arranged at the top end of the threaded rod 502.

[0036] The first connecting block 504 is welded at the bottom end of the threaded rod 502, the second connecting block 505 is rotatably connected outside the first connecting block 504, the positioning plate 506 is welded at the bottom of the second connecting block 505, the bottom of the positioning plate 506 is welded with a protruding block, and the protruding block of the positioning plate 506 is arranged in the vertical through hole of the fixing block 3.

[0037] When multiple positioning blocks 401 are attached to the surface of the furniture, the handle 503 is rotated by hand. During the rotation of the handle 503, the threaded rod 502 is rotated, which in turn causes the threaded rod 502, located inside the threaded hole of the fixing plate 501, to move vertically. At this time, the first connecting block 504 at the bottom of the threaded rod 502 can rotate inside the second connecting block 505. Simultaneously, the positioning plate 506 at the bottom of the second connecting block 505 can move vertically. The protrusion at the bottom of the positioning plate 506 will move within the vertical through hole of the fixing block 3, so that the protrusion at the bottom of the positioning plate 506 will press and adhere to the positioning block 401, thereby fixing the positioning block 401. At this time, the cylinder 2 pushes the multiple positioning blocks 401 to clamp and position the furniture.

[0038] The implementation principle of the workpiece positioning device for a furniture processing center disclosed in this application is as follows:

[0039] First, place the furniture on the workbench 1. Then, by activating the fixing block 3 on the output end of the cylinder 2, the fixing block 3 is displaced by the cylinder 2. At this time, the fixing block 3 will drive the positioning component 4 to contact the furniture. After the positioning component 4 is attached to the surface of the furniture, the fixing component 5 will effectively fix it, thereby maintaining the stability of the furniture during subsequent processing.

[0040] Secondly, during the movement of the fixed block 3, the positioning block 401 on the fixed block 3 changes position inside the fixed block 3 after contacting the furniture. At this time, multiple positioning blocks 401 can be squeezed by the spring 403 on the outside of the guide rod 402, so that the positioning block 401 can be stably attached to the surface of the furniture.

[0041] Finally, when multiple positioning blocks 401 are attached to the surface of the furniture, the handle 503 is rotated by hand. During the rotation of the handle 503, the threaded rod 502 is rotated, thereby allowing the threaded rod 502, which is located inside the threaded hole of the fixing plate 501, to move vertically. At this time, the first connecting block 504 at the bottom of the threaded rod 502 can rotate inside the second connecting block 505. At this time, the positioning plate 506 at the bottom of the second connecting block 505 can move vertically simultaneously. The protrusion at the bottom of the positioning plate 506 will move within the vertical through hole of the fixing block 3, thereby pressing and adhering the protrusion at the bottom of the positioning plate 506 to the positioning block 401, thus fixing the positioning block 401. At this time, the multiple positioning blocks 401 are clamped and positioned by the push of the cylinder 2.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
