Some models integrate CNC systems to achieve automated operation and are widely used in the manufacturing of gears and transmission components.

[0003] During the production of racks, the blanks need to be cut to the appropriate lengths first, and then the racks are produced according to the blanks. When the rack blanks are sawn, the existing equipment either pushes the blanks under the sawing machine for sawing or fixes the rack blanks while moving the sawing machine to cut them. Pushing the blanks can easily cause the blanks to tilt during the conveying process, resulting in tilted saw edges, which affects the subsequent processing of the racks.

[0004] In view of this, we propose a sawing device for steering gear rack blanks. Utility Model Content

[0005] The purpose of this utility model is to provide a steering gear rack blank sawing device, which solves the problem that the sawing edge may be tilted when the rack blank is pushed and cut during sawing.

[0009] Preferably, the bottom end of the pull rod is located inside the T-groove, and a guide rod is passed through the surface of the end of the pull rod located inside the T-groove, and the guide rod is fixedly connected to the pull rod.

[0010] Preferably, a guide groove is provided on the inner side of the T-shaped groove. The end of the guide groove closer to the center of the sawing table is lower, and the end farther from the center of the sawing table is higher. Both ends of the guide rod are inserted into the inner side of the guide groove.

[0011] Preferably, a lifting platform is slidably connected to the inner side of the gantry frame, a sawing machine is installed on the inner side of the lifting platform, and a cylinder is installed on the top surface of the gantry frame, with the output shaft of the cylinder fixedly connected to the top surface of the lifting platform.

[0014] By means of the above technical solution, this utility model provides a sawing device for steering gear rack blanks.

[0015] It has at least the following beneficial effects:

[0016] 1. In this utility model, as the lifting platform descends, the push rod hinged to the inner side of the hinge block gradually pushes the linkage plate. The T-shaped slider of the positioning component slides within the T-shaped groove, causing the linkage plate to move. The linkage plate, through the connecting rod, pushes the positioning plate closer to the blank. During the positioning process, the guide rod at the bottom of the pull rod slides along the guide groove inside the T-shaped groove. Due to the inclined design of the guide groove, the end closer to the center of the sawing table is lower, and the end farther from the center is higher. The movement of the guide rod will cause the pull rod to move upward or downward. When the guide rod moves towards the center of the sawing table, the pull rod will be pulled downward through the guide rod sliding along the guide groove, causing the pressure plate to compress the spring one downward. The pressure plate will gradually press the edges of the rack blank on both sides to ensure that the blank does not shift during the sawing process.

[0017] 2. In this invention, as the lifting platform descends, the hinge block at its bottom pushes the linkage plate via a push rod, causing the positioning component to adjust its position synchronously to accommodate blanks of different lengths. Debris generated during the cutting process is discharged through the auxiliary groove and the cutting groove, and the cut blank is automatically unloaded through the unloading groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] A sawing device for steering gear rack blanks, such as Figure 1 - Figure 5As shown, the machine includes a sawing table 1 and a gantry frame 3. The surface of the sawing table 1 is provided with an auxiliary groove 4, a material ejection groove 5, and a cutting groove 6. A material pushing assembly 7 is provided above the sawing table 1. The material pushing assembly 7 consists of an electric push rod and a push plate. It also includes a positioning assembly 2, which is used to ensure that the edge of the rack blank is cut neatly during sawing and to prevent the rack blank from shifting during cutting. The positioning assembly 2 includes a T-shaped groove 21, which is opened on the inner side of the sawing table 1. A T-shaped slider 22 is slidably connected to the inner side of the T-shaped groove 21. A linkage plate 23 is fixedly connected to the top surface of the T-shaped slider 22. A connecting rod 24 is slidably connected to the inner side of the linkage plate 23. During sawing, the cylinder 214 at the top of the gantry frame 3 drives the lifting platform 213 to descend, thereby driving the sawing machine 216 to cut the blank. As the lifting platform 213 descends, it gradually pushes the linkage plate 23 through the push rod 211 hinged to the inner side of the hinge block 212. The T-shaped slider 22 of the positioning component 2 slides in the T-shaped groove 21, causing the linkage plate 23 to move. The linkage plate 23 pushes the positioning plate 25 closer to the blank through the connecting rod 24. The end of the connecting rod 24 away from the linkage plate 23 is fixedly connected to the positioning plate 25. The inner side of the positioning plate 25 is slidably connected to the pull rod 26. The top end of the pull rod 26 is fixedly connected to the pressure plate 27. When the guide rod 29 moves toward the center of the sawing table 1, the pull rod 26 will slide along the guide groove 210 through the guide rod 29 and be pulled downward, causing the pressure plate 27 to compress the spring 28 downward. The pressure plate 27 will gradually press the edges of the rack blank to ensure that the blank will not shift during the sawing process. A spring 28 is fitted on the outer side of the pull rod 26. One end of the spring 28 is fixedly connected to the bottom surface of the pressure plate 27, and the other end of the spring 28 is fixedly connected to the top surface of the positioning plate 25. The bottom end of the pull rod 26 is located inside the T-slot 21, and a guide rod 29 passes through the surface of the end of the pull rod 26 located inside the T-slot 21. The guide rod 29 is fixedly connected to the pull rod 26. A guide groove 210 is provided inside the T-slot 21. The end of the guide groove 210 closer to the center of the sawing table 1 is lower, and the end farther from the center of the sawing table 1 is higher. Both ends of the guide rod 29 are inserted into the inside of the guide groove 210. During the positioning process, the guide rod 29 at the bottom of the pull rod 26 slides along the guide groove 210 inside the T-slot 21. Because the guide groove 210 is designed with an inclination, with the end closer to the center of the sawing table 1 being lower and the end farther from the center being higher, the movement of the guide rod 29 will cause the pull rod 26 to move upward or downward. A lifting platform 213 is slidably connected to the inner side of the gantry frame 3. A sawing machine 216 is installed inside the lifting platform 213. A cylinder 214 is installed on the top surface of the gantry frame 3, and the output shaft of the cylinder 214 is fixedly connected to the top surface of the lifting platform 213. A hinge block 212 is fixedly connected to the bottom of the lifting platform 213. A push rod 211 is hinged to the inner side of the hinge block 212. A spring 215 on the outer side of the connecting rod 24 provides elastic buffering between the positioning plate 25 and the linkage plate 23, further stabilizing the position of the billet.During sawing, the cylinder 214 at the top of the gantry 3 drives the lifting platform 213 to descend, thereby driving the sawing machine 216 to cut the blank. Simultaneously, the hinge block 212 at its bottom pushes the linkage plate 23 via the push rod 211, causing the positioning assembly 2 to adjust its position synchronously to accommodate blanks of different lengths. The end of the push rod 211 away from the hinge block 212 is inserted into the top of the linkage plate 23, and the push rod 211 is hinged to the linkage plate 23. A second spring 215 is sleeved on the outside of the connecting rod 24. One end of the second spring 215 is fixedly connected to the surface of the linkage plate 23, and the other end of the second spring 215 is fixedly connected to the surface of the positioning plate 25.

[0027] In use, the steering gear rack blank sawing equipment of this utility model places the rack blank on the sawing table 1 when sawing is required, and the push plate is driven by the electric push rod of the push assembly 7 to push the blank towards the positioning assembly 2. During sawing, the cylinder 214 at the top of the gantry 3 drives the lifting platform 213 to descend, driving the sawing machine 216 to cut the blank. As the lifting platform 213 descends, it gradually pushes the linkage plate 23 through the push rod 211 hinged to the inner side of the hinge block 212. The T-shaped slider 22 of the positioning assembly 2 slides in the T-shaped groove 21, driving the linkage plate 23 to move. The linkage plate 23 pushes the positioning plate 25 closer to the blank through the connecting rod 24. During the positioning process, the guide rod 29 at the bottom of the pull rod 26 slides along the guide groove 210 inside the T-shaped groove 21. Since the guide groove 210 is inclined, the end closer to the center of the sawing table 1 is low and the end farther from the center is high. The movement of the guide rod 29 will drive the pull rod 26 to move up or down. When the guide rod 29 moves toward the center of the sawing table 1, the pull rod 26 is pulled downwards by sliding along the guide groove 210 via the guide rod 29, causing the clamping plate 27 to compress the spring 28 downwards. The clamping plate 27 gradually presses the edges of the rack blank together to ensure that the blank does not shift during sawing. At the same time, the spring 215 on the outside of the connecting rod 24 provides elastic buffering between the positioning plate 25 and the linkage plate 23, further stabilizing the blank position. During sawing, the cylinder 214 at the top of the gantry 3 drives the lifting platform 213 to descend, driving the sawing machine 216 to cut the blank. As the lifting platform 213 descends, the hinge block 212 at its bottom pushes the linkage plate 23 through the push rod 211, causing the positioning component 2 to adjust its position synchronously to accommodate blanks of different lengths. The debris generated during the cutting process is discharged through the auxiliary groove 4 and the cutting groove 6, and the cut blank is automatically unloaded through the unloading groove 5.
