[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. During the production and processing of the elevator, both sides of the door panel need to be processed and polished;

[0003] Traditionally, elevator door panels are processed by clamping them on both sides with clamps;

[0004] There are some problems. The traditional fixture is complicated to disassemble and cannot be flipped during the processing. When processing the other side, it is easy to replace the front and back sides of the motor door panel multiple times, delaying the progress of the work. For this reason, we propose an auxiliary clamping device for elevator door panel processing. Utility Model Content

A clamping mechanism is provided inside the shell, so that the elevator door panel can be clamped and disassembled without complicated steps, which reduces a lot of time spent on fixing the elevator door panel and improves production efficiency.

[0010] Furthermore, it also includes a single-chip microcomputer, which is arranged at the front end of the upper side of the bottom plate, and the input end of the single-chip microcomputer is electrically connected to an external power supply to facilitate the regulation of electrical operation.

[0011] Furthermore, the rotating mechanism includes a motor, a pulley 1, a belt, a pulley 2 and a rotating shaft. The motor is fixedly connected to the top of the support, the right end of the output shaft of the motor is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected between the two vertical plates, the left and right ends of the rotating shaft are fixedly connected to pulley 1, the opposite outer ends of the two rotating shafts are fixedly sleeved with pulley 2, the pulley 1 and the vertically adjacent pulley 2 are connected by belt transmission, the input end of the motor is electrically connected to the output end of the single-chip microcomputer, so as to facilitate flipping processing on either side.

[0012] Furthermore, the clamping mechanism includes an inclined column 1, a guide slide groove, a slide bar, an inclined column 2, a slide column, a spring, an extrusion block and an inclined column 3. The interior of the shell is provided with a U-shaped slide hole. The inclined column 1 and the inclined column 2 are respectively slidably connected to the interior of the U-shaped slide hole. The two inclined columns 2 are located between the two inclined columns 1. The front and rear inner walls of the U-shaped slide hole are provided with guide slide grooves. The front and rear sides of the inclined column 3 are provided with slide bars. The inclined column 3 is slidably connected to the interior of the guide slide groove through the slide bars on the front and rear sides. The top of the inclined column 2 is fixedly connected with a slide column. The slide columns are slidably connected to the small-diameter slide hole on the upper surface of the shell. A spring is fixedly connected between the top wall of the U-shaped slide hole and the top end of the inclined column 2. The springs are sleeved on the outer surface of the slide column. The top of the slide column is fixedly connected with an extrusion block, which can ensure stable clamping and facilitate disassembly.

[0013] Furthermore, the upper surfaces of the extrusion blocks are provided with anti-slip strips to prevent sliding during processing.

[0014] Furthermore, the top of the shell is fixedly connected to an L-shaped clamp, the top of the L-shaped clamp is fixedly connected to a mounting frame, an electric push rod is provided inside the mounting frame, the telescopic end of the electric push rod is fixedly connected to the top of the inclined column one, and the input end of the electric push rod is electrically connected to the output end of the single-chip microcomputer to provide clamping power.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the elevator door panel processing auxiliary clamping device has the following advantages:

[0017] 1. The operation of the electric push rod is controlled by the single-chip microcomputer. The telescopic end of the electric push rod pushes the inclined column 1 downward. While the inclined column 1 moves downward, the inclined surface at the bottom contacts the outer inclined surface of the inclined column 3 and squeezes downward, thereby limiting the position of the inclined column 3 through the guide slide groove and the slide bar to ensure that it will not roll during the sliding process, thereby pushing it inward and then sliding inward. While the inclined column 3 slides inward, the outer inclined surface of the inclined column 3 contacts the inclined surface at the bottom of the inclined column 2 and squeezes inward, thereby pushing the inclined column 2 upward and then sliding upward. While sliding upward, the elevator door panel on the extrusion block is tightly attached to the L-shaped clamping plate through the sliding column until it is clamped tightly and not loose. The anti-slip strip on the extrusion block is used to prevent the elevator door panel from falling during the processing. When disassembling the door panel, the operation of the electric push rod is regulated by the single-chip microcomputer, and the telescopic end of the electric push rod is retracted, driving the inclined column one to slide upward, thereby canceling the squeezing force on the inclined column three. At the same time, the inclined column three slides outward through the guide slide groove and the slide bar, thereby canceling the squeezing force on the inclined column two. When the inclined column two slides downward, the force of the spring is canceled, thereby releasing the force of the extrusion block and taking out the elevator door panel after processing. This achieves the goal of clamping and disassembling the elevator door panel without complicated steps, thereby reducing a lot of time spent on fixing the elevator door panel.

[0018] 2. After one side of the processing is completed, the single-chip microcomputer controls the operation of the motor. The output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the pulleys on both sides to rotate. The pulley is connected to the pulley 2 through a belt drive, and then the outer shell is driven to rotate through the rotating shaft. Thus, any side of the elevator door panel can be processed, which is convenient for completing an elevator door panel at one time without multiple processing, thereby improving production efficiency.

[0028] Shell 11: They are all fixedly connected to the inner end of the rotating shaft. The interior of the shell 11 is provided with a clamping mechanism 6, which includes an inclined column 1 61, a guide slide 62, a slide bar 63, an inclined column 2 64, a slide bar 65, a spring 66, an extrusion block 67 and an inclined column 3 68. The interior of the shell 11 is provided with a U-shaped slide hole. The inclined column 1 61 and the inclined column 2 64 are respectively slidably connected to the interior of the U-shaped slide hole. The two inclined columns 2 64 are located between the two inclined columns 1 61. The front and rear inner walls of the U-shaped slide hole are provided with a guide slide 62.

The input end of the electric push rod 7 is electrically connected to the output end of the single-chip microcomputer 2. First, the elevator door panel is placed on the extrusion block 67, and the single-chip microcomputer 2 is used to control the elevator door panel. The operation of the electric push rod 7 is regulated, and the inclined column 1 61 is pushed downward by the telescopic end of the electric push rod 7. While the inclined column 1 61 moves downward, the inclined surface at the bottom contacts the outer inclined surface of the inclined column 3 68 and squeezes downward, thereby limiting the position of the inclined column 3 68 through the guide slide groove 62 and the slide bar 63 to ensure that it will not roll during the sliding process, thereby pushing it inward and then sliding inward. While the inclined column 3 68 slides inward, the outer inclined surface of the inclined column 3 68 contacts the inclined surface at the bottom of the inclined column 2 64 and squeezes inward, thereby pushing the inclined column 2 64 upward and then sliding upward. While sliding upward, the elevator door panel on the extrusion block 67 is tightly attached to the L-shaped clamping plate 9 through the sliding column 65 until it is clamped and not loose, and the extrusion block The anti-slip strip 10 on 67 prevents the elevator door panel from falling during the processing. When the door panel is removed after the processing is completed, the operation of the electric push rod 7 is regulated by the single-chip microcomputer 2, and the telescopic end of the electric push rod 7 is retracted, driving the inclined column 1 61 to slide upward, thereby canceling the squeezing force on the inclined column 3 68.

When the inclined column 2 64 slides downward, the force of the spring 66 is canceled, thereby releasing the force of the extrusion block 67, and taking out the elevator door panel after the processing, so that the elevator door panel can be clamped and disassembled without complicated steps, reducing a lot of time used for fixing the elevator door panel.

[0029] The working principle of the elevator door panel processing auxiliary clamping device provided by the utility model is as follows: when processing the elevator door panel, the elevator door panel is first placed on the extrusion block 67, and the operation of the electric push rod 7 is controlled by the single chip microcomputer 2, and the inclined column 1 61 is pushed downward by the telescopic end of the electric push rod 7. While the inclined column 1 61 moves downward, the inclined surface at the bottom contacts the outer inclined surface of the inclined column 3 68 and squeezes downward, and then the inclined column 3 68 is limited by the position of the guide slide groove 62 and the slide bar 63 to ensure that it will not roll during the sliding process, so as to be pushed inward and then slide inward. While the inclined column 3 68 slides inward, the inclined surface of the outer side of the inclined column 3 68 contacts the inclined surface of the bottom of the inclined column 2 64 and squeezes inward, thereby pushing the inclined column 2 64 upward and then sliding upward. While sliding upward, the elevator door panel on the extrusion block 67 is tightly attached to the L-shaped clamping plate 9 through the slide column 65 until it is clamped and not loose, and the elevator door panel is prevented from falling during the processing by the anti-slip strip 10 on the extrusion block 67. After clamping is completed, the electric push rod 7 is used to prevent the elevator door panel from falling. On one side of the elevator door panel, the processing of one side is completed by adjusting the motor 51 through the single chip microcomputer 2, and the output shaft of the motor 51 drives the rotating shaft 55 to rotate, and the rotating shaft 55 drives the pulleys 1 52 on both sides to rotate, and the pulley 1 52 is connected to the pulley 2 54 through the belt 53, and then drives the shell 11 to rotate through the rotating shaft, so that any side of the elevator door panel can be processed. When the door panel is removed after the processing is completed, the electric push rod 7 is controlled to operate through the single chip microcomputer 2, and the telescopic end of the electric push rod 7 is recovered, driving the inclined column 1 61 to slide upward, thereby canceling the squeezing force on the inclined column 3 68, and at the same time, the inclined column 3 68 slides outward through the guide groove 62 and the slide bar 63, thereby canceling the squeezing force on the inclined column 2 64, and when the inclined column 2 64 slides downward, the force of the spring 66 is canceled, thereby releasing the force of the extrusion block 67, and taking out the elevator door panel after processing, so as to achieve the elevator door panel clamping and disassembly without complicated steps, reducing a lot of time used for fixing the elevator door panel.
