DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] like Figure 1-Figure 3 As shown, the embodiment of the present invention provides a furniture leg sampling and detection device, comprising:
[0023] A protective shell 1 is provided with a cover door, and an observation window is provided on the cover door. Inspection is carried out inside the protective shell 1, which can effectively protect the personal safety of the staff. A plurality of placement bases are fixedly connected to the protective shell 1, and the plurality of placement bases are installed in conjunction with the protective shell 1, thereby ensuring that the protective shell 1 can be placed stably. A working groove is provided on the protective shell 1, and an intelligent hydraulic press 2 is installed on the protective shell 1. The intelligent hydraulic press 2 is a mature existing technology, and a specific pressure value can be input into it. The output end of the intelligent hydraulic press 2 is provided through the protective shell 1, and the intelligent hydraulic press 2 and the working groove cooperate with each other. A testing platform 3 is installed in the working groove through a guide sliding assembly. The guide sliding assembly includes guide slides opened on both side walls of the working groove. Two guide sliders are fixedly connected to the testing platform 3, and the two guide sliders are slidably connected to the two guide slides respectively, thereby ensuring that the testing platform 3 can slide up and down normally;
[0024] The fixing assembly includes a working chamber provided in the detection table 3, in which a working screw 4 is rotatably connected, and the threads on both sides of the working screw 4 are in opposite directions. Two working slide blocks 5 are threadedly connected to the working screw 4, so that when the working screw 4 rotates, the two working slide blocks 5 can move toward each other, and the distance between the two working slide blocks 5 can be adjusted according to the size of the furniture legs. A limiting slide bar 6 is also fixedly connected in the working chamber, and the two working slide blocks 5 are slidably connected to the limiting slide bar 6. The limiting slide bar 6 passes through the two working slide blocks 5, thereby limiting the two working slide blocks 5, so that the two working slide blocks 5 can only slide toward each other along the direction of the working screw 4. Two working sliding openings are provided on the detection table 3, and the two working slide blocks 5 are slidably connected to the two working slide blocks 5 respectively, thereby ensuring that the working slide blocks 5 can slide normally;
[0025] The ends of the two working slides 5 away from the limit slide 6 are both equipped with fixed splints 7 through multiple buffer assemblies. The two fixed splints 7 work together to clamp the furniture legs. The buffer assembly includes a buffer slide 18 fixedly connected to the working slide 5, and a buffer spring 19 is fixedly connected inside the buffer slide 18. The other end of the buffer spring 19 is fixedly connected to a buffer link 20. The buffer link 20 is fixedly connected to the fixed splint 7, and the fixed splint 7 will push the buffer link 20 to slide, thereby buffering the clamping fixation under the elastic force of the buffer spring 19 to avoid damage to the furniture legs. A transmission assembly is also installed in the working chamber. The transmission assembly includes a working motor 18 fixedly connected to the working chamber, and a bevel gear 19 is fixedly connected to the output end of the working motor 18. A bevel gear 2 10 is fixedly connected to the working screw 4. The bevel gear 2 10 is installed at the middle end of the working screw 4. The bevel gear 19 and the bevel gear 2 10 are meshed with each other, so that the working motor 18 can drive the working screw 4 to rotate through gear transmission;
[0026] A height adjustment component is installed in the working groove, which includes a threaded sleeve 11 rotatably connected to the working groove, a lifting screw 12 threaded in the threaded sleeve 11, and an intermediate pad 13 fixedly connected to the end of the lifting screw 12 away from the threaded sleeve 11. The end of the intermediate pad 13 away from the lifting screw 12 is fixedly connected to the detection table 3, and the intermediate pad 13 can support the detection table 3. Combined with the self-locking characteristics of the threaded connection, it can effectively prevent the intelligent hydraulic press 2 from pushing the detection table 3 downward when pressing down. Two telescopic support rods 14 are also fixedly connected in the working groove, and the other ends of the two telescopic support rods 14 are fixedly connected to the detection table 3. The stability of the testing platform 3 is further improved. A bevel gear three 15 is fixedly connected to the threaded sleeve 11, a working motor two 16 is fixedly connected in the working groove, and a bevel gear four 17 is fixedly connected to the output end of the working motor two 16. The bevel gear three 15 and the bevel gear four 17 are meshed with each other, so that the working motor two 16 can drive the threaded sleeve 11 to rotate through gear transmission. A limit plate is fixedly connected in the working groove, and the lifting screw 12 slides through the limit plate. A limit block is provided on the limit plate, and a limit slide groove is provided on the lifting screw 12. The limit block and the limit slide groove cooperate to limit the lifting screw 12 so that it can only slide along the direction of the threaded sleeve 11.
[0027] During the use of the present invention, the staff first places the furniture leg to be tested on the testing table 3, and then starts the working motor 1 8, so that the bevel gear 1 9 fixedly connected to the output end of the working motor 1 8 rotates. Due to the characteristics of gear meshing, the bevel gear 2 10 also starts to rotate, thereby driving the working screw 4 to rotate. Due to the characteristics of the threaded connection, the two working slide blocks 5 will slide toward each other along the direction of the working screw 4 under the limiting action of the limiting slide bar 6, thereby driving the two fixed splints 7 to move together, so that furniture legs of different sizes can be clamped and fixed. At the same time, during the clamping and fixing process, the fixed splint 7 will push the buffer connecting rod 20 to slide along the buffer slide cylinder 18, thereby playing a buffering effect under the elastic force of the buffer spring 19;
[0028] Then the staff closes the cover door of the protective shell 1 and inputs the critical pressure value into the intelligent hydraulic press 2. The intelligent hydraulic press 2 will press its output end down and contact the furniture leg. If the furniture leg does not break or other problems occur under the set pressure, it means that the furniture leg is of qualified quality. When the furniture leg is short and the working stroke of the intelligent hydraulic press 2 cannot contact it, the staff only needs to start the working motor 2 16 to make the bevel gear 4 17 rotate. Due to the characteristics of the gear meshing, the bevel gear 3 15 will also start to rotate, thereby driving the threaded sleeve 11 to rotate. Due to the characteristics of the threaded connection, the lifting screw 12 will slide upward along the direction of the threaded sleeve 11 under the limiting action of the limit plate, thereby driving the intermediate pad 13 to move together, so that the detection platform 3 slides upward with the cooperation of the guide slide groove and the guide slider, and then the detection work can be carried out.
[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
