[0026] Reference Figure 1 、 Figure 2 、 Figure 3 The present invention proposes an arc-shaped rack processing grinder, comprising a machine base 100, a clamping mechanism 200 and a processing mechanism 300. The clamping mechanism 200 is connected to the machine base 100 and comprises a clamping assembly and a first angle adjustment assembly. The clamping assembly is used to clamp the rack and expose the portion of the rack to be processed. The first angle adjustment member 240 comprises an arc-shaped slide 241, a pulley 2423 and a driving member 243. The processing mechanism 300 is arranged adjacent to the clamping mechanism 200 and is located on the inner side of the curved arc of the bracket. The processing mechanism 300 comprises a base 310, a mounting seat 320 and a grinding head motor 330. The base 310 is connected to the machine base 100. The grinding head motor 330 is connected to and drives the grinding disc 331. A second angle adjustment member 340 is provided between the grinding head motor 330 and the mounting seat 320 to adjust the angle between the grinding disc 331 and the rack in the vertical direction. The pulley 2423 is connected to the clamp assembly and embedded in the arc slide 241. The driving member 243 is connected to and drives the pulley 2423 to rotate so as to roll along the arc slide 241. The clamp assembly follows the pulley 2423 to move along the arc slide 241 to adjust the horizontal angle between the grinding plate 331 and the rack.

[0027] In a specific embodiment, the machine base 100 serves as the supporting foundation of the entire equipment and is made of high-strength cast iron material with good stability and load-bearing capacity. The clamp assembly is used to firmly clamp the rack and expose the part to be processed. The first angle adjustment assembly includes an arc-shaped slide 241, a pulley 2423 and a drive member 243. The arc-shaped slide 241 is fixed on the machine base 100, and its shape matches the arc-shaped profile of the rack; the pulley 2423 is connected to the bottom of the clamp assembly and embedded in the arc-shaped slide 241; the drive member 243 is connected to the pulley 2423 through a transmission mechanism, driving it to roll along the arc-shaped slide 241, thereby driving the clamp assembly and the rack to move along the arc track to adjust the horizontal angle between the grinding plate 331 and the rack. The machining mechanism 300 includes a base 310, a mounting base 320, and a grinding head motor 330. The base 310 is fixed to the machine base 100, providing stable support for the entire machining mechanism 300. The mounting base 320 is mounted on the base 310 to secure and support the grinding head motor 330. The grinding head motor 330 is connected to the grinding wheel 331 via a transmission reducer or coupling, and drives the grinding disc 331 to rotate, achieving the grinding process. A second angle adjustment member 340 is provided between the grinding head motor 330 and the mounting base 320. The tilt angle of the grinding head motor 330 can be adjusted manually or electrically to change the vertical angle between the grinding disc 331 and the rack.

[0028] It should be noted that, through the arc-shaped slideway 241 and the pulley 2423 structure of the first angle adjustment component, while matching the fixation and processing of the arc-shaped rack, the angle adjustment of the grinding head motor 330 by the second angle adjustment member 340 can achieve precise adjustment of the angle between the grinding disc 331 and the rack in the horizontal and vertical directions, thereby realizing the automated processing of the front and back tooth edges and chamfers of the arc-shaped rack, ensuring precise control of the grinding process, and improving processing accuracy. In addition, the design of the clamping mechanism 200 and the processing mechanism 300 is highly flexible and adjustable, and can adapt to the processing requirements of straight racks of different specifications and sizes. In addition, by replacing different fixture modules and grinding discs 331, the processing of other types of racks can also be achieved. On the other hand, automated processing reduces the physical labor and skill requirements of the operator, reducing labor intensity. At the same time, by optimizing the processing process and reducing human errors, production safety and stability are improved.

[0029] Reference, 1 and Figure 2In the specific clamp assembly, the support frame 210 serves as the main load-bearing structure and is firmly connected to the pulley 2423, ensuring the stable movement of the clamp assembly on the arc slide 241. The cylinder 221 bracket 220 is installed on the top of the support frame 210 to support and fix the cylinder 221. The cylinder 221 drives the pressure plate 222 to move up and down by adjusting the internal air pressure. The pressure plate 222 cooperates with the support platform 230 to form a source of power for clamping the rack. The support platform 230 is designed with appropriate grooves or bosses to match the bottom or side of the rack to increase the stability of the clamping. When the cylinder 221 pushes the pressure plate 222 down, the pressure plate 222 and the support platform 230 jointly press the rack to achieve stable clamping.

[0030] Furthermore, to match the contour of the curved rack, the support platform 230, pressure plate 222, and support frame 210 are all designed with specially designed curved surfaces. These curved surfaces are located on the side closest to the processing mechanism 300, and their curvature is exactly the same as the curvature of the curved slideway 241. This ensures that the fixture assembly will not interfere with the rack or processing mechanism 300 when moving along the curved slideway 241. This not only improves processing smoothness, but also avoids unnecessary wear and collision.

[0031] Reference Figure 2 Furthermore, a positioning flange 2411 is provided on the side wall of the curved slide 241 facing away from the processing mechanism 300 to enhance the guidance and stability of the pulley 2423. The support frame 210 is connected to the pulley 2423 via a fixed frame 242. The fixed frame 242 is provided with a fixing groove 2422 with an opening 2421 facing the positioning flange 2411. The pulley 2423 is embedded in the fixing groove 2422 and partially extends out of the opening 2421 to closely abut the positioning flange 2411. In this way, when the pulley 2423 rolls on the curved slide 241, it is not only driven by the driving member 243 but also limited by the positioning flange 2411, preventing the pulley 2423 from deviating from the predetermined trajectory. The output end of the driving member 243 passes through the bottom of the fixing groove 2422 and is directly connected to the pulley 2423, ensuring efficient power transmission.

[0032] Furthermore, in order to improve the accuracy and stability of the movement of the fixture assembly along the arc-shaped slide 241, a guide groove 2412 is also provided at the top of the arc-shaped slide 241. Accordingly, guide wheels are installed at the bottom of the support frame 210. These guide wheels are embedded in the guide groove 2412 and respectively abut the groove walls on both sides of the guide groove 2412. When the pulley 2423 rolls on the arc-shaped slide 241, the guide wheel rolls along the trajectory of the guide groove 2412, providing additional guiding force for the fixture assembly. The dual guiding mechanism of the pulley 2423 and the guide wheel ensures that the fixture assembly can move accurately along the arc-shaped slide 241, providing a strong guarantee for high-precision processing.

[0033] It should be noted that in other embodiments, without affecting the sliding position, the pulley 2423 has a position sensor integrated inside or outside it. The position sensor can be a magnetic encoder, a photoelectric encoder or a linear displacement sensor, etc. The specific type is selected according to the system requirements and environmental conditions. The sensor is fixed on the pulley 2423 or connected to the pulley 2423 shaft to ensure that the position change of the pulley 2423 on the arc slide 241 can be accurately sensed. At the same time, the sensor and the control system are connected via wired or wireless means to transmit position data in real time. The real-time feedback and closed-loop control of the position sensor ensure the precise movement of the pulley 2423 on the arc slide 241, thereby achieving precise adjustment of the horizontal angle between the grinding disc 331 and the rack. This greatly improves the processing accuracy and reduces the processing error caused by angle deviation. Since the adjustment process is automated and precisely controlled, manual intervention and downtime are reduced, and processing efficiency is improved. At the same time, the system can quickly adjust the angle according to processing requirements, shortening the processing cycle.

[0034] Reference Figure 3 In a specific embodiment, the main body of the second angle adjustment member 340 is a housing 341 with a horizontal axis. The housing 341 is made of a sturdy and durable material to withstand vibration and force during the processing. The bottom of the housing 341 is connected to the mounting base 320, and the axis of the housing 341 serves as the reference line for the entire adjustment member. A drive assembly is disposed within the housing 341. The drive assembly, connected to the housing 341, is responsible for driving the grinding head motor 330 for angle adjustment. The assembly integrates the necessary transmission mechanisms and control systems to ensure the accuracy and stability of the angle adjustment. The grinding head motor 330 is connected to the output end of the drive assembly and is located at a specific position within the housing 341. The axis of the grinding head motor 330 is perpendicular to the axis of the housing 341, allowing the grinding head motor 330 to rotate around the axis of the housing 341. This maximizes the conversion of the output of the second angle adjustment member 340 into a change in the vertical angle between the grinding disc 331 and the rack to be processed, improving the adjustment efficiency and, in turn, the efficiency of the rack processing.

[0035] Specifically, the drive assembly includes a first motor 342 and a drive shaft connected to the first motor 342, the axis of the drive shaft is collinear with the axis of the housing 341, and the end of the drive shaft is connected to the grinding head motor 330. As a power source, the first motor 342 is responsible for providing the torque required to drive the grinding head motor 330 to rotate. The drive shaft is connected to the output end of the first motor 342, and its axis is collinear with the axis of the housing 341. The drive shaft rotates under the drive of the motor, thereby driving the grinding head motor 330 connected thereto to adjust the angle. The end of the drive shaft is connected to the grinding head motor 330 through a coupling or a keyway to ensure synchronous rotation between the two.

[0036] Furthermore, in order to stably install and support the grinding head motor 330 and its grinding disc 331, the grinding head motor 330 is provided with a motor bracket 350, which is composed of a connecting plate 351 and a mounting plate 352 arranged perpendicular to each other. The connecting plate 351 is connected to the end of the drive shaft to ensure that the motor bracket 350 can rotate with the rotation of the drive shaft. The mounting plate 352 is used to install and fix the grinding head motor 330 and the grinding disc 331, and is designed to have sufficient strength and rigidity to withstand the load during the processing. The connecting plate 351 is tightly connected to the end of the drive shaft to ensure the accuracy and stability of the transmission. The mounting plate 352 firmly fixes the grinding head motor 330 and the grinding disc 331 in the designated position by screws or other fasteners.

[0037] Furthermore, in order to improve the load-bearing capacity and rigidity of the connecting plate 351 and prevent deformation or breakage during processing, a mounting groove 353 is provided on the connecting plate 351 to accommodate and fix the end of the drive shaft. The design of the mounting groove 353 takes into account transmission accuracy and installation convenience to ensure that the drive shaft can be accurately inserted and fixed in the groove. Reinforcing ribs 355 are provided between the outer wall of the mounting groove 353 and the mounting plate 352. The function of the reinforcing ribs 355 is to increase the overall rigidity and strength of the connecting plate 351 and prevent it from bending or twisting when bearing loads. These reinforcing ribs 355 are usually made of the same material as the connecting plate 351 and are firmly connected to the connecting plate 351 by welding or other means.

[0038] Furthermore, to protect the grinding disc 331 and prevent debris from flying during machining, a cover 354 is provided on the side of the connecting plate 351 facing away from the drive shaft. Specifically, the cover 354 is semi-disc-shaped, with a diameter slightly larger than that of the grinding disc 331, ensuring that it completely covers the grinding disc 331 and prevents debris from flying. The edges of the cover 354 can be designed with a smooth transition shape to reduce collision and friction with surrounding objects.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
