Description

Technical Field

[0001] This utility model relates to the field of rack and pinion machining technology, and in particular to a rack and pinion saw with safety protection. Background Technology

[0002] In modern industrial production, the saw is an important cutting device widely used in various fields, especially in the automotive manufacturing industry, where the production of racks requires extremely high precision and safety. As a key component of the automotive steering system, the quality of the rack directly affects the vehicle's safety and handling performance. Therefore, during the rack production process, when using a saw for cutting, it is essential to ensure both operational safety and cutting precision.

[0003] The production of toothed racks typically employs circular saws for cutting, making them the preferred equipment for rack processing due to their high cutting speed and precision. However, when a circular saw operates at high speed, the high-speed rotation of the saw disc generates significant kinetic energy. When the saw disc contacts the rack blank, debris often flies out, and if the saw disc breaks during the cutting process, it can cause injury to the operator. Therefore, we propose a safer, more protective rack saw. Utility Model Content

[0023] like Figure 1-4 As shown, a safety-protected rack saw includes two processing tables 1. A rotatable clamping assembly 7 is fixedly installed on the upper surface of each processing table 1. Adjusting columns 2 are fixedly installed on both sides of one processing table 1. A mounting frame 3 is fixedly installed on the upper ends of the two adjusting columns 2. A saw disc 17 is slidably installed on the bottom surface of the mounting frame 3. A conveyor table 4 is fixedly installed between the two processing tables 1, and the conveyor table 4 is positioned below the saw disc 17. First electric telescopic rods 5 are fixedly installed on the outer walls of both ends of the mounting frame 3. A pressure plate 6 is fixedly installed on the bottom surface of the first electric telescopic rods 5. A movable protective assembly is provided on the upper surface of the processing table 1 outside the clamping assembly 7. The clamping assembly 7 specifically includes a bottom... The device consists of a base, a second electric telescopic rod, and a clamping plate. The clamping plate is driven by the second electric telescopic rod to clamp both sides of the rack blank. The saw disc 17 is rotatably mounted on the support frame, and the support frame is connected to the bottom surface of the mounting frame 3. The clamping components 7 set on the upper surface of the two processing tables 1 can clamp both sides of the rack blank. The two first electric telescopic rods 5 move downward to press the pressure plate 6 onto the upper surface of the rack blank, which can fix the rack blank, making it easier for the saw disc 17 to cut the rack blank. Moreover, it eliminates the need for workers to manually press and fix the rack blank, improving the safety of the device during use. The protective components further prevent debris from flying and injuring people when the saw disc 17 comes into contact with the rack blank.

[0024] like Figure 1As shown, the protective assembly includes two protective plates 8. Adjusting gears 10 are fixedly installed on the lower ends of the two protective plates 8 on their sides that are close to each other. The center of the bottom surface of the adjusting gear 10 is rotatably connected to the upper surface of the processing table 1, and the two adjusting gears 10 are meshed together. A drive gear 11 is rotatably installed on the upper surface of the processing table 1 at a position corresponding to one of the adjusting gears 10. Through the transmission between the drive gear 11 and the adjusting gear 10, the two protective plates 8 can be adjusted to tilt. With four tilted protective plates 8 on the upper surfaces of the two processing tables 1, the periphery of the contact point between the saw disc 17 and the rack blank can be protected, thus preventing flying fragments from injuring people during sawing. Simultaneously, a barrier can be set around the high-speed rotating saw disc 17 to prevent workers from directly contacting the saw disc 17 in case of accidents.

[0025] like Figure 2 As shown, a fixed frame is fixedly installed on the upper surface of the processing table 1 at the position corresponding to the drive gear 11. A servo motor 12 is fixedly installed on the fixed frame, and the output end of the servo motor 12 is fixedly connected to the center position of the drive gear 11. The drive gear 11 is driven to rotate by the servo motor 12. The servo motor 12 is a prior art technology and has a self-locking function. When the servo motor 12 drives the drive gear 11 to rotate to the corresponding position, it can stay stably.

[0026] like Figure 1 and Figure 2 As shown, a connecting strip 9 is provided between the two protective plates 8 on their sides that are close to each other. The two ends of the connecting strip 9 are fixedly connected to the outer walls of the ends of the two protective plates 8 respectively, and the connecting strip 9 is flexible. The flexible connecting strip 9 itself is elastic and can cover the gap between the two protective plates 8.

[0027] like Figure 3 As shown, collection slots are provided on both sides of the processing table 1. A collection box 13 is slidably installed inside the collection slot. A handle 16 is fixedly installed on the outer wall of the collection box 13. By holding the handle 16, the collection box 13 can be taken out from the inside of the collection slot. After the collection box 13 is taken out, the debris collected inside can be poured out for unified recycling and reuse.

[0028] like Figure 3 As shown, support bars 15 are fixedly installed on both sides of the upper inner wall of the collection tank, and a drain plate 14 is placed on the upper surface of the two support bars 15; the support bars 15 support the bottom sides of the drain plate 14, and the drain plate 14 can be removed from the upper end of the collection tank.

[0029] like Figure 3 As shown, the sluice plate 14 is matched with the upper end of the collection tank, and multiple rectangular slots are opened through the sluice plate 14; the sluice plate 14 blocks the upper end of the collection tank, and the debris falling on the upper surface of the sluice plate 14 can fall into the interior of the collection box 13 through the multiple through rectangular slots.

[0030] The working principle of this utility model is as follows: In use, this type of saw can be used to process automotive rack blanks. The long, strip-shaped blank is placed on the upper surface of the conveyor table 4. The saw disc 17 mounted on the bottom surface of the mounting frame 3 can cut the long, strip-shaped rack blank, thus quantitatively dividing it. When cutting the long, strip-shaped rack blank, the user can start the servo motor 12 to drive the drive gear 11 to rotate. The drive gear 11 meshes with one of the adjusting gears 10 on the upper surface of the processing table 1. When the drive gear 11 rotates, the adjusting gear 10 meshing with it rotates simultaneously. Similarly, the two meshing adjusting gears 10 rotate in opposite directions simultaneously. Thus, during the saw disc 17 sawing the blank... The two protective plates 8 can be adjusted to tilt through the transmission between the drive gear 11 and the adjusting gear 10. Four tilted protective plates 8 are provided on the upper surface of the two processing tables 1, which can protect the periphery of the contact position between the saw disc 17 and the rack blank, thereby preventing flying fragments from injuring people during sawing. At the same time, a barrier can be set around the high-speed rotating saw disc 17 to prevent workers from directly contacting the saw disc 17 in case of accidents, and also to prevent fragments from flying out and injuring workers when the saw disc 17 breaks during rotation. The tilted protective plates 8 can block the debris generated when the saw disc 17 saws the rack blank, so that the debris falls to the upper surface of the processing table 1, and then falls into the collection box 13 through the rectangular groove opened on the upper surface of the stencil 14.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
