Description

Technical Field

[0001] This utility model belongs to the technical field of brake disc processing equipment, and in particular relates to a fully automatic production line for brake discs based on collaborative feeding and combined turning and grinding processing. Background Technology

[0002] Brake discs are a critical component of vehicle safety systems, and their manufacturing quality significantly impacts driving safety. Industrialized brake disc manufacturing, through large-scale production, stringent quality control, technological innovation, and green manufacturing, comprehensively supports the automotive industry's upgrade towards high efficiency, safety, and environmental friendliness, while also providing key component support for high-tech fields such as aerospace.

[0003] Traditional brake disc turning and grinding equipment is mostly a standalone machine, with separate lathes and grinders operating in sequence. The processing of a single part requires going through the process of "blank → rough turning → finish turning → grinding → inspection", which requires multiple clamping and positioning, resulting in a long processing time. Repeated clamping causes an increase in cumulative positioning error, damages machining accuracy, leads to the brake disc end face parallelism exceeding the standard, quality control failure, and economic losses.

[0004] Improved automated production lines (such as CN 114988008 A) only integrate turning and inspection modules; the grinding process still needs to be outsourced, leading to extended processing cycles. Furthermore, existing automated production lines suffer from poor logistics coordination: the gantry robot and the feeding system are not synchronized in a timely manner, resulting in high tray idle rates and insufficient overall equipment utilization.

[0005] Therefore, there is an urgent need for a new technical solution to address this problem. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a fully automated production line for brake discs based on collaborative feeding and combined turning and grinding, in order to solve the problems of efficiency loss and precision loss caused by the separation of turning and grinding processes in the prior art, as well as the low level of automation of the production line and the need for manual intervention.

[0007] The technical solution adopted by this utility model is a fully automatic production line for brake discs based on collaborative feeding and combined turning and grinding, including a machine tool. The inside of the machine tool is a processing space, and a grinding module and a Z-axis turning module are integrated in the processing space. A truss assembly, a feeding C-axis assembly and a roller unloading channel are installed on one side of the machine tool, and a roller loading channel is installed on the other side of the machine tool. The truss assembly includes an X-axis body, which is disposed on the side of the machine tool. A first X-axis guide rail is provided on the X-axis body. A slide plate is slidably connected along the first X-axis guide rail. A first Z-axis body is fixed on the slide plate. The first Z-axis body reciprocates along the X-axis direction when the first X-axis servo motor is started. The first Z-axis body reciprocates along the Z-axis direction when the first Z-axis servo motor is started. A first chuck is provided at the lower end of the first Z-axis body. A jaw is installed on the first chuck for gripping workpieces. The feeding C-axis assembly includes a C-axis main support. The lower part of the C-axis main support is fixedly connected to the machine tool, and the upper part of the C-axis main support is provided with a C-axis guide rail. The C-axis guide rail is slidably connected to the material tray body through the C-axis guide rail. A first material tray and a second material tray are installed on the material tray body. The material tray body reciprocates along the C-axis direction when the C-axis servo motor is started. When workpiece A is being processed inside the machine tool, the external logistics move synchronously. Workpiece B arrives at the loading position through the roller feeding channel. The main body of the first Z-axis of the gantry assembly moves to the corresponding position and descends along the Z-axis. The first chuck grabs the workpiece B to be processed. Once the grab is successful, workpiece B is placed above the first material tray. The first material tray carries workpiece B along the C-axis to the side of the processing space. After workpiece A is finished in the processing space, the Z-axis turning module grabs the finished workpiece A and places it on the second material tray. After placement, the C-axis moves, and the Z-axis turning module grabs the workpiece B to be processed on the first material tray and puts it into the processing space for further processing. Workpiece A moves along the C-axis to below the first chuck of the gantry assembly. The first chuck puts the finished workpiece A into the roller unloading channel, and the cycle repeats.

[0008] The Z-axis turning module includes a spindle unit, on which a main motor is fixedly connected. The main motor drives the spindle inside the spindle unit to rotate through a main motor pulley. A second chuck is connected to the lower end of the spindle, and jaws are installed on the second chuck. The jaws clamp the workpiece through the action of a rotary cylinder sleeved on the spindle. The spindle unit is connected to the slide saddle via a first Z-axis lead screw and a first Z-axis guide rail. When the second Z-axis servo motor is started, the spindle unit reciprocates along the first Z-axis guide rail. The slide saddle is connected to the machine tool bed via the X-axis lead screw and the second X-axis guide rail. The entire Z-axis turning module reciprocates along the X-axis direction when the second X-axis servo motor is started, and different tool holders are installed on the tool holder of the machine tool to complete the turning.

[0009] The grinding module includes a grinding base, which is slidably connected to the upper and lower slide plates via a second Z-axis guide rail and a second Z-axis lead screw. The second Z-axis lead screw is a forward and reverse rotary lead screw, and the threads at both ends of the forward and reverse rotary lead screw are forward and reverse threads. The upper and lower slide plates move towards the center simultaneously when the third Z-axis servo motor is started. The upper and lower slide plates are respectively equipped with an upper spindle and a lower spindle via bearings at their centers. An upper grinding wheel is installed at the end of the upper spindle, and the other end of the upper spindle is connected to the upper grinding wheel motor via a belt. A lower grinding wheel is installed at the end of the lower spindle, and the other end of the lower spindle is connected to the lower grinding wheel motor via a belt. The upper and lower grinding wheel motors drive the two grinding wheels to rotate along the center line of the upper and lower spindles. When the workpiece is being ground, the upper and lower grinding wheels move towards the center simultaneously, and the workpiece is ground between the two rotating grinding wheels.

[0010] The machine tool is equipped with a double precision turning lower tool holder, and the grinding module is equipped with a double precision turning upper tool holder. The double precision turning upper tool holder moves with the lower grinding wheel. The double precision turning upper tool holder cooperates with the double precision turning lower tool holder to complete the machining of the workpiece's braking surface. After machining, the workpiece's braking surface is moved between the upper and lower grinding wheels to complete the grinding.

[0011] Through the above design scheme, this utility model can bring the following beneficial effects: 1. By integrating the grinding module and turning module on the same machine tool base, the grinding module grinds synchronously from top to bottom, with uniform force and symmetrical and uniform double-sided patterns. The clamping structure is a surface contact, which can keep the workpiece from deformation and ensure the grinding accuracy of the workpiece. At the same time, combined processing with the turning module can complete the turning and double precision turning of the workpiece.

[0012] 2. Turning and double-sided grinding can be completed in a single setup, greatly improving machining efficiency.

[0013] 3. The combination of machining and logistics collaborative control enables multi-station continuous machining through the collaboration of the feeding C-axis and the gantry, achieving a breakthrough in both machining efficiency and precision. Attached Figure Description
