[0029] A positioning device for nailing a seat is used for accurately positioning the seat cushion m and the edge covering object g when nailing the edge covering of the seat cushion, referring to Figures 1-7, including a frame 1, a containing mechanism 2, a pushing mechanism 3 and a positioning mechanism 4, wherein the containing mechanism 2 is provided with a containing groove 21 for placing a cushion m, the shape of the containing groove 21 is matched with the shape of the cushion m, that is, the position of the cushion m is limited by the containing groove 21, the pushing mechanism 3 has a pushing assembly arranged around the edge of the containing groove 21 and movable, the movement of the pushing assembly enables the pushing assembly to switch between a first position entirely located outside the containing groove and a second position at least partially located above the containing groove, and the pushing assembly is used to push the welt g to move towards the surface of the cushion m in the process of switching from the first position to the second position, so that the welt g can be closely fitted on the surface of the cushion m, and the positioning mechanism 4 has a plurality of positioning pieces 41 located above the containing groove 21, and the plurality of positioning pieces 41 are arranged in a ring shape, the positioning pieces 41 are movable up and down, and the positioning pieces 41 are used to position the welt g closely fitted on the surface of the to-be-nailed component on the to-be-nailed component.

[0030] In the embodiment, before the welt g of the cushion m is nailed, the welt g is pushed to move by the pushing assembly, so that all the welt g can be closely fitted on the surface of the cushion m, and then the welt g closely fitted on the surface of the cushion m is temporarily fixed on the cushion m by the plurality of positioning pieces 41, so as to ensure that the welt g can be closely fitted on the surface of the cushion m during nailing. Compared with the operation mode that the operator pulls part of the welt g while nailing in the prior art, on the one hand, the displacement of the other part of the welt g caused by manually pulling part of the welt g is avoided, the position of the welt g is stable during nailing, which helps to maintain the flatness and consistency of the welt g before and after nailing, improves the product quality, and on the other hand, the operator does not need to pull the welt g while nailing, which not only reduces the work intensity of the operator but also reduces the safety hazard of the operator during nailing operation.

[0031] In the embodiment, the end of the positioning piece 41 close to the cushion m is provided with a sharp part 41a for penetrating the welt g located below the corresponding positioning piece 41 and penetrating into the cushion m, so that the welt g can be temporarily fixed on the surface of the cushion m, thereby avoiding the movement of the welt g relative to the cushion m when the welt g is subjected to external force during nailing, ensuring that the welt g can be in close contact with the cushion m during nailing, and improving the product quality after nailing. At the same time, after the nailing operation is completed, the positioning piece 41 can be controlled to move upward, so as to pull the positioning piece 41 out of the cushion m, which is convenient to operate.

[0032] In the embodiment, the nailing position is located between the positioning member 41 and the edge of the cushion m, so when the positioning member 41 penetrates into the cushion m, the position of the positioning member 41 has a clearance distance from the edge of the cushion m, thereby avoiding the position of the positioning member 41 interfering with the nailing operation. Moreover, after nailing is completed, the excess edge cover g can be cut off, so that the part of the edge cover g penetrated by the sharp part 41a will not affect the quality of the product.

A plurality of positioning members 41 are arranged around the pressing disc 51. In operation, the pressing rod 53 is driven by the first driver 52 to vertically descend, thereby driving the pressing disc 51 to contact the cushion m, so as to press the cushion m on the accommodating groove 21. The pressing disc 51 applies a continuous pressing force to the surface of the cushion m, so as to fix the position of the cushion m, thereby effectively preventing the cushion m from shifting or shaking during nailing, ensuring that the cushion m remains in a fixed position, ensuring the accuracy of the nailing position, and helping to improve the quality of the product. Moreover, the pressing disc 51 is arranged above the central region of the accommodating groove 21, so that when the pressing disc 51 is pressed on the cushion m, the pressing disc 51 contacts the central region of the cushion m, so that the pressing force of the pressing disc 51 can be uniformly distributed on the cushion m, thereby more effectively fixing the cushion m and preventing the cushion m from being deformed or damaged due to excessive local pressure during nailing.

[0035] In the embodiment, the positioning mechanism 4 comprises a plurality of second drivers 42, and a connecting assembly 43 is arranged corresponding to each second driver 42, and a plurality of positioning members 41 are arranged on each connecting assembly 43. The plurality of second drivers 42 are arranged on the pressing rod 53 through a connecting disc 55, and the connecting disc 55 is sleeved on the outer surface of the pressing rod 53. The second driver 42 is used to drive the connecting assembly 43 to move. The plurality of second drivers 42 are arranged on the pressing rod 53 through the connecting disc 55, so that the positioning mechanism 4 can be integrated on the pressing rod 53 without interfering with the up-down movement of the pressing rod 53, thereby eliminating the need for additional structures to install the positioning mechanism 4, and reducing the production and manufacturing cost of the device.

[0036] More specifically, the connecting assembly 43 comprises a first connecting member 431 connected with the second driver 42 and a second connecting member 432 used to install the positioning member 41. The movable end of the second driver 42 is hinged to one end of the first connecting member 431. One end of the first connecting member 431 is connected with the second connecting member 432. The middle part of the first connecting member 431 is hinged to the upper surface of the pressing disc 51. Thus, the upward movement of the movable end of the second driver 42 can drive the positioning member 41 to move downward, and the downward movement of the movable end of the second driver 42 can drive the positioning member 41 to move upward. In this structure, the connecting assembly 43 is installed in the form of hinge, so that the connecting assembly 43 can maintain a stable state during the up-down movement without being damaged, which helps to improve the service life. It should be noted that the movable end of the second driver 42 refers to the part that can move in the second driver 42, such as the telescopic rod in the electric telescopic rod.

[0037] In the embodiment, the advancing mechanism 3 comprises a plurality of third drivers 32 and an advancing assembly. The advancing assembly comprises a plurality of advancing members 31 arranged at intervals. A third driver 32 is arranged corresponding to each advancing member 31. The third driver 32 is used to drive the advancing member 31 to move, that is, the corresponding advancing member 31 is controlled to move by the third driver 32, so that the advancing assembly can be switched between the first position and the second position. The third driver 32 here can be an electric telescopic rod or a pneumatic cylinder.

[0038] In the embodiment, the lower side of the advancing member 31 has a flattening surface parallel to the upper surface of the cushion m. The flattening surface is used to locate the bound material g during the movement of the advancing member 31 from the outside of the accommodating groove 21 to the inside of the accommodating groove 21. The flattening surface is used to press the bound material g on the surface of the cushion m when the advancing member 31 is located above the accommodating groove 21. At the same time, in order to ensure that the bound material g can be tightly attached to the surface of the cushion m, the distance between the flattening surface and the upper surface of the cushion m is slightly smaller than the thickness of the bound material g, so that the bound material g can be fully extruded between the advancing member 31 and the cushion m, and the bound material g can be tightly attached to the surface of the cushion m.
