[0002] The car is a box-shaped space used by elevators to carry and transport people and materials. The car is generally composed of the car bottom, car wall, car top, car door and other main parts. It is the car body part used by the elevator to carry passengers or goods and other loads. The elevator car bottom often uses panels, and the panels often need to be riveted and fixed. The existing blocking mechanism uses blocks to block rigidly, and the width of the panels needs to be exactly the same to ensure the same riveting position each time. However, in actual production, the width of the panels is not necessarily exactly the same, which makes it impossible to produce automatically. Therefore, improvements are needed.

[0014] 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.

[0015] Reference Figure 1-3 , a positioning and blocking mechanism for rivetless riveting of elevator car floor panels, used in pairs in elevator car floor panel riveting equipment, including a vertically arranged mounting plate 1, a blocking mechanism 2 slidably connected to the mounting plate 1, a travel switch 3 slidably connected to the mounting plate 1, and a first proximity switch 4 and a second proximity switch 5 respectively arranged on both sides of the blocking mechanism 2, the first proximity switch 4 and the second proximity switch 5 are fixed to the side of the mounting plate 1 through a first bracket, and the first proximity switch is arranged close to the travel switch.

[0016] In this technical solution, the elevator car bottom is formed by riveting a number of metal panels with groove structures. The panels have different widths due to specifications or material collection reasons. The mounting plate is fixed to the position of the original blocking device of the riveting equipment and is connected to the control system of the riveting equipment. The travel switch is arranged on the side close to the incoming material of the riveting equipment, first contacts the panel to be riveted, and then the blocking mechanism extends out. The positioning blocking mechanism for rivet-free riveting of elevator car bottom panels has a compact structure, the travel switch confirms the incoming material, and the blocking structure is movably arranged to meet the riveting needs between panels of different widths, thereby realizing automated production.

[0017] Furthermore, the blocking mechanism 2 includes a blocking block 21 slidably connected to the mounting plate 1 and a first cylinder 22 driving the blocking block 21 , and the first proximity switch 4 and the second proximity switch 5 are arranged on a side of the blocking block 21 away from the first cylinder 22 .

[0018] In this technical solution, the first cylinder is fixed to the mounting plate through a cylinder seat, and the piston rod of the first cylinder is connected to the corresponding end of the blocking block. The cylinder seat and the connecting structure belong to conventional technology and will not be elaborated here. The blocking block is slidably connected to the mounting plate through a guide rail to ensure the moving direction of the blocking block.

[0019] Furthermore, a blocking head 211 is protruded from the top of one end of the blocking block 21 close to the first bracket toward one side of the first bracket, and a third proximity switch 6 is disposed in the blocking head 211 .

[0020] In this technical solution, a wiring groove is recessed in the blocking block to protect the cable of the third proximity switch. The blocking head is inserted into the puzzle board and contacts the inner wall of the puzzle board. The third proximity switch confirms that the puzzle board has been moved into place, thereby starting riveting.

[0021] Furthermore, the travel switch 3 is connected to the second cylinder 32 via the second bracket 31 , and the second cylinder 32 is fixed to the mounting plate 1 via the third bracket 33 .

[0022] In this technical solution, the second bracket is an L-shaped structure and is fixed to the push plate of the second cylinder, and the third bracket is directly formed by cutting a channel steel or bending a metal plate.

[0023] During actual use, the distance from the travel switch to the third proximity switch and the distance from the first proximity switch to the second proximity switch are both smaller than the width of the narrowest panel. The travel switch is set on the side of the blocking mechanism close to the incoming material. In the initial state, the first cylinder is in a retracted state, and the second cylinder drives the travel switch to extend. The riveting equipment starts to feed continuously. When the first side of the panel contacts the travel switch, the second cylinder retracts. At the same time, the first cylinder drives the blocking block to extend. When the first side contacts the blocking head, the first proximity switch and the third proximity switch sense the panel, but the second proximity switch does not sense the panel, so riveting is not performed. The first cylinder retracts and the panel is released to continue passing. At the same time , the second cylinder drives the travel switch to extend; when the middle edge of the panel contacts the travel switch, the second cylinder retracts, and at the same time, the first cylinder drives the blocking block to extend, and when the middle edge contacts the blocking head, the first proximity switch, the second proximity switch and the third proximity switch simultaneously sense the panel, completing the riveting and releasing it, until the last edge of the panel contacts the blocking head, the second proximity switch and the third proximity switch sense the panel, the first proximity switch does not sense the panel, and the riveting is not performed. The first cylinder retracts, and the panel is released to continue moving forward, completing all riveting and feeding. In this process, even if the widths of the panels are different, the blocking structure can still be accurately positioned to achieve automated riveting production.

[0024] In summary, the positioning and blocking mechanism for rivet-free riveting of elevator car bottom panels has a compact structure, a travel switch confirms incoming materials, and a movably arranged blocking structure to meet the riveting requirements between panels of different widths, thereby realizing automated production.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
