Description

Technical Field

[0001] This invention relates to the field of automated processing technology, and more specifically, to an elevator guide rail stepping feeding mechanism. Background Technology

[0002] With the development of industrial manufacturing technology, higher requirements have been placed on the precision and efficiency of elevator guide rail processing. In the elevator guide rail processing, the stepping feeding mechanism, as one of the key components, is responsible for accurately and stably transporting the elevator guide rail to the designated position. Traditional feeding methods mostly rely on manual operation or simple mechanical devices, which are not only inefficient but also difficult to guarantee feeding accuracy, especially in high-speed continuous production environments.

[0003] Existing elevator guide rail stepping feeding mechanisms can achieve basic feeding functions and intermittent conveying through a single cylinder drive. However, due to the lack of coordinated lifting and horizontal stepping, the slide is prone to deviation or shaking when directly pushed in a suspended state, affecting the feeding accuracy and stability.

[0004] In addition, there are problems such as complicated adjustment for model change, difficulty in compatibility with elevator guide rails of different lengths, and high energy consumption caused by the reliance on bidirectional cylinder drive for reset and return.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Summary of the Invention

[0006] In view of the problems in the related technologies, the present invention proposes an elevator guide rail stepping feeding mechanism to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by the present invention is as follows: An elevator guide rail stepping feeding mechanism includes: a frame; several lifting components disposed inside the frame for driving a lifting frame to rise and fall, so that a slide detaches from or falls back into the frame; a slide disposed on top of the lifting components for supporting the elevator guide rail; a lifting frame disposed between the lifting components and the slide; and a stepping component disposed at the bottom of the slide for driving the slide to move horizontally one station distance after the slide is lifted, and pulling it back to its original position after the slide falls.

[0008] Furthermore, in order to ensure that the lifting frame and slide move smoothly and accurately, several movable seat guide rails are symmetrically arranged on both sides inside the frame, and one side of each movable seat guide rail is movably connected to the lifting frame; several upper rollers and lower rollers are respectively arranged on the top and bottom of the lifting frame; the top of the upper roller is movably connected to the slide; and the bottom of the lower roller is connected to the lifting assembly.

[0009] Furthermore, in order to flexibly adjust the eccentricity of the drive cam, change the lifting stroke, and adapt to the lifting requirements of elevator guide rails of different specifications, the lifting assembly includes a fixed plate set inside the frame, and the fixed plate is flush with the ground plane of the frame; the top of the fixed plate is symmetrically provided with support columns, the top of the support columns is provided with bearing seats, the bearing seats are provided with linkage shafts, and a drive power device is connected between the two sets of linkage shafts; the other side of the linkage shaft is provided with a drive cam that abuts against several lower rollers.

[0010] Furthermore, in order to achieve layered support of the elevator guide rail during lifting and conveying and placement at the workstation, with clear division of labor, effectively prevent the elevator guide rail from slipping and ensure stable support, the slide is provided with several first support parts arranged at intervals along the feeding direction. On one side of the first support part and at the top of the frame, several second support parts are provided, and the distance between adjacent second support parts is the distance between two processing workstations.

[0011] Furthermore, to achieve smooth horizontal reciprocating movement of the slide with high positioning accuracy, the stepping component includes a reset component and a drive component respectively disposed at the bottom and top of the slide. The drive component is positioned between the frame and the slide and acts alternately with the reset component. The reset component includes a mounting base disposed at the bottom of the slide. Vertical guide rails are symmetrically arranged on one side of the mounting base. A movable connecting seat is movably disposed on one side of the two sets of vertical guide rails. A movable joint is connected to one side of the movable connecting seat. A reset slide is connected to the bottom of the movable joint and is movably disposed on the reset guide rail on the mounting base. A fixing plate is disposed on one side of the mounting base, and several reset springs are disposed between the fixing plate and the reset slide. The drive component includes a mounting bracket symmetrically disposed at the top of the frame. A stepping drive cylinder is disposed on one side of the mounting bracket along the length direction of the elevator guide rail workpiece. A guide slider is disposed at the output end of the stepping drive cylinder, and a reset stop block abutting against the slide is disposed at one end of the guide slider.

[0012] Furthermore, in order to achieve zoned bearing of thrust and tension, uniform and reasonable force distribution, and to ensure stable and reliable forward and retraction of the slide block, a push plate and a baffle are symmetrically arranged on the top of the slide block in sequence. The push plate is located on the side away from the reset component and is used to abut against the lifting component to bear the stepping thrust and transmit the thrust to the slide block, driving the slide block to step forward one station distance in the horizontal direction. The baffle is located on the side close to the reset component and is used to connect with the reset component to bear the reset tension and pull the slide block back to the initial position after the lifting component unloads the force, so as to realize the reciprocating stepping feeding of the slide block.

[0013] Furthermore, in order to coordinate with the step feeding rhythm to complete the continuous processing of multiple processes of elevator guide rails and improve the overall production automation and processing efficiency, several processing stations are set up in the frame to process the elevator guide rails station by station when the slide moves the elevator guide rails to the corresponding stations.

[0014] The beneficial effects of this invention are as follows: 1. The present invention has a reasonable and reliable structure and is easy to operate. Through the coordinated cooperation of the lifting component and the stepping component, the precise stepping feeding of the elevator guide rail is realized, which effectively improves the processing efficiency and automation level, while reducing the cost of manual intervention and labor intensity.

[0015] 2. This invention, by setting up a lifting component, uses the eccentric rotation of the drive cam to drive the lifting frame to rise and fall, so that the slide detaches from the frame before stepping and falls back to the frame after stepping, avoiding the offset and swaying when the slide is suspended and pushed. At the same time, the cooperation of the upper roller and the lower roller realizes the smooth lifting of the elevator guide rail, ensuring the stability of the feeding process and the accuracy of the elevator guide rail positioning.

[0016] 3. By setting up a stepping component, the present invention utilizes the alternating action of the stepping drive cylinder and the return spring, combined with the force transmission of the push plate and the baffle, to realize the unidirectional thrust stepping of the slide and automatic spring reset. At the same time, the guiding cooperation between the reset guide rail and the vertical guide rail ensures the trajectory accuracy of the slide's reciprocating motion, making it easy to meet the processing requirements of elevator guide rails of different lengths.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] According to an embodiment of the present invention, an elevator guide rail stepping feeding mechanism is provided.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8 As shown, the elevator guide rail stepping feeding mechanism according to an embodiment of the present invention includes: a frame 1; a plurality of lifting components 2 disposed inside the frame 1 for driving the lifting frame 4 to rise and fall, so that the slide 3 disengages from or falls back into the frame 1; a slide 3 disposed on the top of the lifting components 2 for supporting the elevator guide rail; the lifting frame 4 disposed between the lifting components 2 and the slide 3; and a stepping component 5 disposed at the bottom of the slide 3 for driving the slide 3 to step forward a distance in the horizontal direction after the slide 3 is lifted, and pulling it back to its original position after the slide 3 falls.

[0023] By utilizing the above-mentioned technical solution, the precise stepping feeding of the elevator guide rail is achieved through the coordinated operation of the lifting component 2 and the stepping component 5, which effectively improves processing efficiency and automation level, while reducing manual intervention costs and labor intensity.

[0024] In one embodiment, for the aforementioned frame 1, several movable seat guide rails 6 are symmetrically arranged on both sides inside the frame 1, and one side of each movable seat guide rail 6 is movably connected to the lifting frame 4; several upper rollers 7 and lower rollers 8 are respectively arranged at the top and bottom of the lifting frame 4; the top of the upper roller 7 is movably connected to the slide 3; and the bottom of the lower roller 8 is connected to the lifting assembly 2. This ensures that the lifting frame 4 and the slide 3 move smoothly, steadily, and with precise positioning.

[0025] In one embodiment, the lifting assembly 2 includes a fixed plate 201 disposed inside the frame 1, and the fixed plate 201 is flush with the ground plane of the frame 1; a support column 202 is symmetrically disposed on the top of the fixed plate 201, a bearing seat 203 is disposed on the top of the support column 202, a linkage shaft 204 is disposed inside the bearing seat 203, and a drive power device 205 is connected between the two sets of linkage shafts 204; a drive cam 206 is disposed on the other side of the linkage shaft 204, which abuts against a plurality of lower rollers 8.

[0026] It should be noted that the drive power unit 205 is composed of a servo motor, a reducer and a coupling connected in sequence. The power output by the servo motor is reduced in speed and increased in torque by the reducer, and then transmitted to the linkage shaft 204 through the coupling. The linkage shaft 204 drives the drive cam 206 to rotate.

[0027] The specific working principle of the lifting assembly 2 is as follows: The driving power device 205 drives the linkage shaft 204 to rotate. The linkage shaft 204 drives the driving cam 206 to rotate through the eccentric mounting hole 207. Since the axis of the linkage shaft 204 is off from the geometric center of the driving cam 206, the driving cam 206 generates an eccentric lifting motion during rotation. The driving cam 206 pushes the lower roller 8 upward. The lower roller 8 drives the lifting frame 4 to rise vertically along the movable seat guide rail 6. During the rise of the lifting frame 4, its upper roller 7 simultaneously lifts the slide 3, causing the slide 3 to detach from the top of the frame 1. When the driving cam 206 rotates past the highest point and enters the descent section, the lifting frame 4 descends along the movable seat guide rail 6 under its own weight and the action of the elastic reset component. The upper roller 7 simultaneously detaches from the elevator guide rail, and the slide 3 falls back to the top of the frame 1, completing one lifting cycle.

[0028] In one embodiment, the slide 3 is provided with a plurality of first support portions 9 arranged at intervals along the feeding direction. On one side of each first support portion 9 and at the top of the frame 1, a plurality of second support portions 10 are provided, with the distance between adjacent second support portions 10 being the distance between two processing stations. This achieves layered support for the elevator guide rail during lifting and conveying and lowering at the workstations, with clear division of labor, effectively preventing slippage of the elevator guide rail and ensuring stable support.

[0029] In one embodiment, the stepper assembly 5 includes a reset member 501 and a drive member 502 respectively disposed at the bottom and top of the slide 3; the drive member 502 is disposed between the frame 1 and the slide 3 and acts alternately with the reset member 501. The reset member 501 includes a mounting base 5011 disposed at the bottom of the slide 3, with vertical guide rails 5012 symmetrically arranged on one side of the mounting base 5011, and movable connecting seats 5013 movably disposed on one side of the two sets of vertical guide rails 5012, with a movable joint 5014 connected to one side of the movable connecting seat 5013; a reset slide 5015 is connected to the bottom of the movable joint 5014, and the reset slide 5015 is movably disposed on the reset guide rail 5016 on the mounting base 5017; a fixing plate 5018 is disposed on one side of the mounting base 5017, and a plurality of reset springs 5019 are disposed between the fixing plate 5018 and the reset slide 5015.

[0030] The driving component 502 includes a mounting bracket 5021 symmetrically arranged on the top of the frame 1. A stepping drive cylinder 5022 is mounted on one side of the mounting bracket 5021, extending along the length of the workpiece on the elevator guide rail. A guide slider 5023 is mounted at the output end of the stepping drive cylinder 5022, and a reset stop 5024 abuts against the slide block 3 at one end of the guide slider 5023. Thus, the extension and retraction of the piston rod of the stepping drive cylinder 5022 enables the slide block 3 to move horizontally reciprocally along the distance between two workstations, resulting in smooth operation and high positioning accuracy.

[0031] The specific working principle of the stepping component 5 is as follows: When the slide block 3 is lifted off the frame 1 by the lifting component 2, the stepping drive cylinder 5022 extends, and its output end abuts against the push plate 11 through the guide slider 5023, pushing the slide block 3 to move one station distance in the horizontal direction. During this process, the reset stop 5024 moves synchronously and stretches the reset spring 5019 to store energy. After the slide block 3 is in place, the lifting component 2 descends to make the slide block 3 fall back to the frame 1. The stepping drive cylinder 5022 retracts to relieve the force, and the reset spring 5019 releases the stored energy. The reset stop 5024 pulls the slide block 3 back to the initial position. At the same time, the reset slide block 5015 slides along the reset guide rail 5016 for guidance, the movable connecting seat 5013 assists in guidance along the vertical guide rail 5012, and the movable section 5014 provides connection floating compensation to realize the reciprocating stepping feeding of the slide block 3.

[0032] In one embodiment, for the slide block 3, a push plate 11 and a baffle 12 are symmetrically arranged on the top of the slide block 3. The push plate 11 is located on the side away from the reset member 501, and is used to abut against the lifting component 2 to bear the stepping thrust and transmit the thrust to the slide block 3, driving the slide block 3 to step forward one station distance in the horizontal direction. The baffle 12 is located on the side close to the reset member 501, and is used to connect with the reset member 501 to bear the reset pull, and after the lifting component 2 releases the force, it pulls the slide block 3 back to the initial position, so as to realize the reciprocating stepping feeding of the slide block 3. This achieves partitioned bearing of thrust and pull, uniform and reasonable force distribution, and ensures the stable and reliable stepping forward and reset retraction actions of the slide block 3.

[0033] In one embodiment, the frame 1 is provided with several processing stations 13, which are used to process the elevator guide rail station by station as the slide 3 moves the elevator guide rail to the corresponding station. This allows for continuous processing of the elevator guide rail through multiple processes in coordination with the stepping feeding rhythm, thereby improving the overall automation level and processing efficiency.

[0034] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0035] like Figures 1-8 As shown, in practical application, the worker places the elevator guide rail on the first support part 9 of the slide 3. The lifting component 2 drives the eccentrically mounted drive cam 206 to rotate through the drive power device 205, lifting the lifting frame 4 and the slide 3 as a whole, so that the slide 3 is separated from the frame 1. When the slide 3 is lifted and separated from the frame 1, the drive component 502 of the stepping component 5 starts to move. The stepping drive cylinder 5022 pushes the guide slider 5023 to move horizontally. The reset stop 5024 at the end of the guide slider 5023 abuts against the push plate 11 on the slide 3, transmitting the stepping thrust to the slide 3, driving the slide 3 to move one workstation distance in the horizontal direction. The elevator guide rail is synchronously moved to the next processing station along with the slide 3.

[0036] As the drive cam 206 of the lifting assembly 2 rotates past its highest point and enters the descent section, the lifting frame 4 descends, the upper roller 7 disengages from the elevator guide rail, the slide 3 falls back to the top of the frame 1, and the elevator guide rail falls back onto the next second support part 10; after the slide 3 continues to descend to the bottom, the reset spring 5019 in the reset component 501 applies a reset pulling force to the baffle 12 on the slide 3 through the reset slide 5015, the movable section 5014 and the movable connecting seat 5013, pulling the slide 3 back to its initial position.

[0037] By repeating the above cycle of lifting-stepping-lowering-resetting, the elevator guide rail can be fed step-by-step along several processing stations 13.

[0038] The specific working principles of the lifting component 2 and the stepping component 5 are as described above.

[0039] In summary, by utilizing the above-mentioned technical solution of the present invention, precise step-feeding of the elevator guide rail is achieved through the coordinated operation of the lifting component 2 and the stepping component 5, effectively improving processing efficiency and automation level, while reducing manual intervention costs and labor intensity. The present invention, by setting up the lifting component 2, uses the eccentric rotation of the drive cam 206 to drive the lifting frame 4 to rise and fall, causing the slide 3 to detach from the frame 1 before stepping and fall back to the frame 1 after stepping, avoiding the offset and swaying of the slide 3 when suspended and pushed. Simultaneously, the cooperation of the upper roller 7 and the lower roller 8 achieves stable lifting of the elevator guide rail, ensuring the stability of the feeding process and the accuracy of the elevator guide rail positioning. This invention, by setting a stepping component 5, utilizes the alternating action of the stepping drive cylinder 5022 and the return spring 5019, combined with the force transmission of the push plate 11 and the baffle 12, to realize the unidirectional thrust stepping and automatic spring reset of the slide block 3. At the same time, the guiding cooperation between the return guide rail 5016 and the vertical guide rail 5012 ensures the trajectory accuracy of the reciprocating motion of the slide block 3, making it easy to meet the processing requirements of elevator guide rails of different lengths.
