Description

Technical Field

[0001] This utility model relates to the field of guide rail processing technology, specifically a guide rail heat treatment device. Background Technology

[0002] The guide rail heat treatment device is a specialized heat treatment equipment designed for guide rail workpieces (such as machine tool guide rails, elevator guide rails, and automated equipment guide rails). Its core function is to optimize the mechanical properties of the guide rail (such as hardness, wear resistance, toughness, and deformation resistance) through controllable heating, heat preservation, and cooling processes. Through targeted processes (such as surface hardening to enhance the wear resistance of the guide rail working surface and overall tempering to eliminate internal stress), this device can significantly improve the service life and running accuracy of the guide rail and is widely used in the guide rail processing stage in the fields of mechanical manufacturing.

[0003] In the existing technology, the existing guide rail heat treatment device lacks an adaptive positioning and guiding mechanism. When using the traditional direct positioning and clamping method, it is impossible to adjust the clamping angle and force according to different guide rails. This can easily cause irregular guide rails to loosen and shake during heating or conveying. This not only affects the uniformity of heating, but may also cause local overheating or uneven cooling due to positional deviation, thus reducing the accuracy of heat treatment. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a guide rail heat treatment device, including a support frame and a support column installed on the top of the support frame. An auxiliary wheel is rotatably connected to the top of the support column, and a toothed ring is rotatably connected to the outer end of the support column. Guide plates are connected to the left and right sides of the top of the support frame, and toothed plates are slidably connected to the top of the guide plates. The two toothed plates are staggered and mesh with the toothed ring. An adjustment frame is connected to the top of the toothed plates, and a lifting plate is slidably connected inside the adjustment frame. A rotating ring is rotatably connected to the top of the lifting plate, and a threaded column is threaded inside the rotating ring. A limit plate is connected to the top of the threaded column. A pulley is movably connected between the lifting plate and the adjustment frame. A motor is installed on the top of the support frame, and a gear is connected to the output end of the motor. The gear meshes with the toothed ring. The motor drives the gear to rotate, and the gear rotation drives the toothed ring to rotate on the support column. The rotation of the toothed ring drives the toothed plates on both sides to move. The toothed plates slide on the guide plates and cooperate with the pulley to position the two sides of the guide rail.

[0005] In a preferred embodiment of this technical solution, a lifting frame is slidably connected to the front inner side of the support frame, and a laser head is connected to the upper inner side of the lifting frame.

[0006] In this preferred embodiment of the technical solution, a water storage frame is connected to the rear end of the lifting frame, and an injection port is provided at the top of the water storage frame.

[0007] Based on the preferred embodiment of this technical solution, the injection port is connected to the water storage frame, and the front end of the water storage frame is connected to several high-pressure nozzles.

[0008] Based on the preferred embodiment of this technical solution, a number of toothed blocks are connected to the lower rear end of the lifting frame, and a toothed column is rotatably connected to the lower inner side of the support frame.

[0009] In the preferred embodiment of this technical solution, the toothed column and the toothed block are meshed and connected, and a motor is connected to the left end of the support frame, with the output end of the motor connected to the toothed column.

[0010] In a preferred embodiment of this technical solution, a controller is connected to the right end of the support frame, and the controller is electrically connected to the motor. Compared with the prior art, the beneficial effects of this utility model are: The positioning mechanism achieves symmetrical opening and closing by engaging a gear and a toothed ring driven by a motor, causing the toothed plates on both sides to slide along the guide plate. This allows for precise lateral positioning of guide rails of different widths. The lifting plate inside the adjustment frame, in conjunction with pulleys, and the threaded connection between the rotating ring and the threaded column, allows for flexible adjustment of the clamping height to accommodate guide rails of different thicknesses. Tightening the rotating ring provides stable locking, preventing wobbling during processing. An auxiliary wheel at the top of the support column reduces conveying friction and protects the guide rail surface. The meshing transmission between the toothed ring and the toothed plates ensures synchronous adjustment on both sides, guaranteeing consistent positioning. The entire system achieves dual adaptive adjustment in both lateral and longitudinal directions, eliminating the need for frequent fixture changes and effectively solving the problem of poor adaptability in traditional devices. This significantly improves the flexibility, stability, and processing accuracy of positioning guidance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-6 This utility model provides an embodiment of a guide rail heat treatment device, including a support frame 1 and a support column 21 mounted on the top of the support frame 1. An auxiliary wheel 22 is rotatably connected to the top of the support column 21, and a toothed ring 23 is rotatably connected to the outer end of the support column 21. Guide plates 24 are connected to the left and right sides of the top of the support frame 1, and toothed plates 25 are slidably connected to the top of the guide plates 24. The two toothed plates 25 are staggered and mesh with the toothed ring 23. An adjusting frame 26 is connected to the top of the toothed plates 25, and a lifting plate 27 is slidably connected inside the adjusting frame 26. A rotating ring 28 is rotatably connected to the top of the lifting plate 27, and a threaded post 29 is threadedly connected inside the rotating ring 28. A limit plate 210 is connected to the top of the threaded post 29. A pulley 211 is movably connected between the lifting plate 27 and the adjusting frame 26. A motor 212 is mounted on the top of the support frame 1, and a toothed ring is connected to the output end of the motor 212. Wheel 213, gear 213 meshes with gear ring 23. Motor 212 drives gear 213 to rotate. The rotation of gear 213 drives gear ring 23 to rotate on support column 21. The rotation of gear ring 23 drives the toothed plates 25 on both sides to move. The toothed plates 25 slide on guide plate 24 and cooperate with pulley 211 to position the two sides of the guide rail. By setting motor 212 to drive gear 213 to mesh with gear ring 23, the toothed plates 25 on both sides are alternately distributed and slide along guide plate 24 to realize the symmetrical opening and closing adjustment of positioning mechanism, which can adapt to the lateral positioning of guide rails of different widths. Lifting plate 27 in adjustment frame 26 slides with pulley 211 and can flexibly adjust the clamping height according to the thickness of guide rail to meet the longitudinal adaptation requirements of guide rails of different thicknesses. The threaded connection between rotating ring 28 and threaded column 29 can accurately adjust the position of limit plate 210. By tightening rotating ring 28 to lock lifting plate 27, stable clamping of guide rails of different specifications is ensured. The auxiliary wheel 22 at the top of the support column 21 reduces friction in the guide rail conveying process. The meshing transmission between the toothed ring 23 and the toothed plate 25 ensures the synchronization of adjustment on both sides. The overall structure achieves dual adaptive adjustment of lateral width and longitudinal height through mechanical linkage, solving the problem that traditional devices are difficult to adapt to various specifications of guide rails, and improving the flexibility and stability of positioning and guidance.

[0015] Please see Figures 1-5A further solution based on this embodiment is as follows: a lifting frame 31 is slidably connected to the front inside of the support frame 1, and a laser head 32 is connected to the upper inside of the lifting frame 31. The sliding of the lifting frame 31 can drive the laser head 32 to flexibly adjust its height to adapt to the heat treatment requirements of guide rails of different thicknesses and achieve precise local heating control.

[0016] Please see Figures 1-5 A further solution based on this embodiment is as follows: a water storage frame 33 is connected to the rear end of the lifting frame 31, and an injection port 34 is provided at the top of the water storage frame 33. The water storage frame 33 can store water, and the injection port 34 can be connected to an external water pipe to provide water for the cooling process after the guide rail heat treatment.

[0017] Please see Figures 2-5 A further solution based on this embodiment is as follows: the injection port 34 is connected to the water storage frame 33, and the front end of the water storage frame 33 is connected to several high-pressure nozzles 35. The high-pressure nozzles 35 can efficiently spray the water in the water storage frame 33 onto the surface of the heat-treated guide rail to achieve rapid quenching.

[0018] Please see Figures 1-5 A further solution based on this embodiment is as follows: a number of toothed blocks 36 are connected to the lower rear end of the lifting frame 31, and a toothed column 37 is rotatably connected to the lower inner side of the support frame 1. The meshing structure of the toothed blocks 36 and the toothed column 37 provides a stable transmission basis for the height adjustment of the lifting frame 31, ensuring that the lifting process is smooth and without jamming.

[0019] Please see Figures 1-5 A further solution based on this embodiment is as follows: the toothed column 37 is meshed with the toothed block 36, and the left end of the support frame 1 is connected to the motor 38. The output end of the motor 38 is connected to the toothed column 37. The motor 38 drives the toothed column 37 to rotate. Through the meshing of the toothed column 37 and the toothed block 36, the lifting frame 31 is precisely lifted and lowered, realizing the electric adjustment of the height of the laser head 32 and the nozzle, and improving the operation accuracy.

[0020] Please see Figures 1-5 A further solution based on this embodiment is as follows: a controller 39 is connected to the right end of the support frame 1. The controller 39 is electrically connected to the motor 38 and the motor 212. The controller 39 realizes the coordinated control of the motor 38 and the motor 212, and can centrally adjust the parameters of positioning, heating, cooling and other links to improve the automation level and operation coordination of the device.

[0021] Working principle: First, the guide rail to be processed is conveyed to the processing area via the auxiliary wheel 22 on the top of the support column 21. The auxiliary wheel 22 reduces the frictional resistance during the conveying of the guide rail by rotating, ensuring smooth conveying. Subsequently, the controller 39 starts the motor 212. The gear 213 at the output end of the motor 212 drives the toothed ring 23 at the outer end of the support column 21 to rotate. Because the toothed ring 23 meshes with the toothed plates 25 distributed alternately on both sides, the rotation of the toothed ring 23 will drive the toothed plates 25 to slide synchronously along the guide plate 24, realizing the symmetrical opening and closing of the positioning mechanism on both sides, thereby completing the lateral positioning according to the width of the guide rail. At the same time, by rotating the rotating ring 28 on the top of the adjusting frame 26, its threaded engagement with the threaded column 29 will drive the lifting plate 27 to slide along the adjusting frame 26, thereby replacing the pulleys 211 of different sizes to adapt to the thickness of the guide rail. After longitudinal positioning is completed, tightening the rotating ring 28 locks the lifting plate 27, ensuring the guide rail is stably clamped. After positioning, the controller 39 controls the motor 38 to start, and the motor 38 drives the toothed column 37 inside the support frame 1 to rotate. The toothed column 37 meshes with the toothed block 36 on the lower rear end of the lifting frame 31, causing the lifting frame 31 to slide along the support frame 1, thereby adjusting the height of the laser head 32 inside the lifting frame 31 so that it is precisely aligned with the part of the guide rail to be heated, achieving targeted local heating. After heating is completed, the water source replenished by the water storage frame 33 through the top injection port 34 forms a high-pressure water flow through several high-pressure nozzles 35 at the front end, which is sprayed onto the heat-treated guide rail surface for rapid quenching, realizing the automated coordination of positioning, heating and cooling processes, and adapting to the heat treatment requirements of guide rails of different specifications.
