Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal surface treatment equipment, specifically to a parallel moving track changing structure for an acid pickling and phosphating production line. Background Technology
[0002] Pickling and phosphating production lines typically consist of multiple processing tanks (such as pickling tanks, washing tanks, phosphating tanks, etc.) connected in series, with workpieces moving between the tanks via suspended conveyor chains or track systems.
[0003] Traditional production lines use fixed tracks. When it is necessary to change workpiece specifications or adjust track spacing, the machine must be stopped to disassemble and reinstall the tracks, resulting in low production efficiency and increased labor costs. In addition, existing track adjustment mechanisms mostly rely on manual operation, which has poor precision and insufficient synchronization, and is prone to workpiece misalignment or jamming. Therefore, there is an urgent need for an automated track changing structure that can quickly adjust track spacing and achieve parallel movement switching. Utility Model Content
[0004] The purpose of this utility model is to provide a parallel moving track changing structure for an acid pickling and phosphating production line, which features rapid and precise adjustment of track spacing, high track changing efficiency, and high compatibility.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a parallel moving track changing structure for an acid pickling and phosphating production line, comprising a frame, linear guide rails, sliding bases, and track sections. Two linear guide rails are provided and are respectively fixedly connected to the front and rear sides of the upper end face of the frame. Two sliding bases are provided and are respectively slidably connected to the upper end faces of the two linear guide rails. Two track sections are provided and are respectively fixedly connected to the upper end faces of the two sliding bases.
[0006] Gears are rotatably connected to the opposite sides of the two sliding bases, and a connecting shaft passing through the two sliding bases is fixedly connected between the two gears. Racks are provided on the opposite sides of the two linear guides, and the two gears are respectively meshed with the two racks.
[0007] To facilitate the translation of the drive track section, in a preferred embodiment of the parallel movement track-changing structure of the pickling and phosphating production line of this utility model, a first pulley is fixedly connected to the outer wall of the front gear, a motor is installed on the left side wall of the front sliding base, the output end of the motor is fixedly connected to a second pulley, and a transmission belt is connected between the first pulley and the second pulley.
[0008] In order to lock and fix the sliding base, as a preferred parallel moving track changing structure of the pickling and phosphating production line of this utility model, a mounting plate is fixedly connected to the right side wall of the front sliding base. A pneumatic pin is vertically installed on the outer wall of the mounting plate, and multiple evenly distributed positioning holes matching the pneumatic pin are opened on the upper end face of the front linear guide rail.
[0009] To facilitate the installation and fixing of the rack, in a preferred embodiment of the parallel moving track changing structure of the pickling and phosphating production line of this utility model, two connecting parts are fixedly connected to the outer wall of the rack, and the other ends of the two connecting parts are fixedly connected to the frame.
[0010] To improve the durability of the track section, as a preferred parallel moving track changing structure of the pickling and phosphating production line of this utility model, the upper end face of the track section is provided with a guide groove, and the inner side of the guide groove is coated with a polytetrafluoroethylene wear-resistant layer.
[0011] To facilitate operation and control of the equipment, in the preferred embodiment of the parallel moving track changing structure of the pickling and phosphating production line of this utility model, both the motor and the pneumatic pin are electrically connected to the external PLC control system.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] When the track spacing needs to be adjusted, the starter motor drives the second pulley to rotate. The second pulley drives the first pulley to rotate via the transmission belt. The first pulley is fixed to the outer wall of the gear in front, thus driving the gear to rotate. The gear further drives the rack meshing with it to move relative to the gear. The rack is fixed to the front of the frame. Therefore, when the gear rotates, it drives the sliding base to slide left and right on the outer wall of the linear guide, thereby driving the track section to translate. Gears are rotatably connected to the opposite sides of the two sliding bases. A connecting shaft passing through the two sliding bases is fixedly connected between the two gears. Thus, the synchronous adjustment of the front and rear track sections is achieved, realizing the rapid and accurate adjustment of the track spacing. This structure solves the problems of low track changing efficiency and poor compatibility in traditional production lines, and is particularly suitable for flexible production of multi-variety, small-batch workpieces.

[0018] Please see Figures 1 to 3 A parallel moving track-changing structure for an acid pickling and phosphating production line includes a frame 1, linear guide rails 2, sliding bases 3, and track sections 4. Two linear guide rails 2 are provided and are respectively fixedly connected to the front and rear sides of the upper end face of the frame 1. Two sliding bases 3 are provided and are respectively slidably connected to the upper end face of the two linear guide rails 2. Two track sections 4 are provided and are respectively fixedly connected to the upper end face of the two sliding bases 3.
[0019] Two sliding bases 3 are rotatably connected to gears 5 on opposite sides, and a connecting shaft 6 is fixedly connected between the two gears 5, passing through the two sliding bases 3. Two linear guides 2 are provided with racks 7 on opposite sides, and the two gears 5 are respectively meshed with the two racks 7.
[0020] In this embodiment: During the actual operation of the production line, at least two sets of frames 1, linear guide rails 2, sliding bases 3, and track sections 4 are included. When the track spacing needs to be adjusted, the motor 9 is started to drive the second pulley 10 to rotate. The second pulley 10 drives the first pulley 8 to rotate through the transmission belt 11. The first pulley 8 is fixed to the outer wall of the gear 5 in front, thereby driving the gear 5 to rotate. The gear 5 further drives the rack 7 meshing with it to move relative to the gear 5. The rack 7 is fixed to the front of the frame 1. Therefore, when the gear 5 rotates, it drives the sliding base 3 to slide left and right on the outer wall of the linear guide rail 2, thereby driving the track section 4 to move horizontally. The two sliding bases 3 are rotatably connected to the opposite sides of each other. A connecting shaft 6 that passes through the two sliding bases 3 is fixedly connected between the two gears 5. Thus, the synchronous adjustment of the two track sections 4 is realized, and the track spacing is quickly and accurately adjusted. This structure solves the problems of low track changing efficiency and poor compatibility of traditional production lines, and is particularly suitable for flexible production of multi-variety, small-batch workpieces.
[0021] As a technical optimization of this utility model, a first pulley 8 is fixedly connected to the outer wall of the front gear 5, a motor 9 is installed on the left side wall of the front sliding base 3, a second pulley 10 is fixedly connected to the output end of the motor 9, and a transmission belt 11 is connected between the first pulley 8 and the second pulley 10.
[0022] In this embodiment: the starter motor 9 drives the second pulley 10 to rotate, and the second pulley 10 drives the first pulley 8 to rotate through the transmission belt 11. The first pulley 8 is fixed to the outer wall of the gear 5 in front, thereby driving the gear 5 to rotate. The gear 5 further drives the rack 7 that meshes with it to move relative to the gear 5.
[0023] As a technical optimization of this utility model, a mounting plate 12 is fixedly connected to the right side wall of the front sliding base 3, and a pneumatic pin 13 is vertically installed on the outer wall of the mounting plate 12. Multiple evenly distributed positioning holes 14 that match the pneumatic pin 13 are opened on the upper end face of the front linear guide 2.
[0024] In this embodiment, a pneumatic pin 13 is vertically installed on the outer wall of the mounting plate 12. When the sliding base 3 slides to the designated position, the pneumatic pin 13 is activated, causing the pneumatic pin 13 to extend downward and insert into the corresponding positioning hole 14, thereby locking and fixing the sliding base 3 to prevent displacement during equipment operation.
[0025] As a technical optimization of this utility model, the outer wall of the rack 7 is fixedly connected to two connectors 15, and the other end of the two connectors 15 is fixedly connected to the frame 1.
[0026] In this embodiment: the other end of the two connectors 15 is fixedly connected to the frame 1, and the rack 7 is easily installed and fixed through the connectors 15.
[0027] As a technical optimization of this utility model, a guide groove 16 is provided on the upper end face of the track section 4, and the inner side of the guide groove 16 is coated with a polytetrafluoroethylene wear-resistant layer.
[0028] In this embodiment: a guide groove 16 is provided on the upper end face of the track section 4 to provide a channel for workpiece conveying. The guide groove 16 is used for workpiece sliding and positioning. The inner side of the guide groove 16 is coated with a polytetrafluoroethylene wear-resistant layer, thereby effectively improving the wear resistance and scratch resistance, and improving the durability of the track section 4.
[0029] As a technical optimization of this utility model, both the motor 9 and the pneumatic pin 13 are electrically connected to the external PLC control system.
[0030] In this embodiment, both the motor 9 and the pneumatic plug 13 are electrically connected to an external PLC control system, which facilitates the operation and control of the motor 9 and the pneumatic plug 13.
[0031] Working principle: When the track spacing needs to be adjusted, the start motor 9 drives the second pulley 10 to rotate. The second pulley 10 drives the first pulley 8 to rotate through the transmission belt 11. The first pulley 8 is fixed to the outer wall of the front gear 5, thereby driving the gear 5 to rotate. The gear 5 further drives the rack 7 that meshes with it to move relative to the gear 5. The rack 7 is fixed to the front of the frame 1. Therefore, when the gear 5 rotates, it drives the sliding base 3 to slide left and right on the outer wall of the linear guide rail 2, thereby driving the track section 4 to translate. The two sliding bases 3 are rotatably connected to the opposite sides of each other. The two gears 5 are fixedly connected by a connecting shaft 6 that passes through the two sliding bases 3. Thus, the synchronous adjustment of the front and rear track sections 4 is realized, and the track spacing is quickly and accurately adjusted.
