Description

Technical Field

[0001] This utility model relates to the field of turning machine tool technology, and in particular to a multi-station synchronous turning machine tool for bearing rings. Background Technology

[0002] Bearing races are a core component of rolling bearings. Their structure is typically a hollow annular part, requiring high-precision geometry (such as roundness, concentricity, and end-face parallelism) and strict dimensional tolerances to ensure smooth operation, load-bearing capacity, and service life. Currently, to improve machining efficiency, some machine tools employ multi-tool synchronous turning technology, using multiple tool turrets or tool posts arranged on the same machine tool to simultaneously machine different parts of the bearing races.

[0003] During bearing machining, a large amount of chips are generated. If these chips are not cleaned in time, they can easily accumulate. This chip accumulation not only directly interferes with the machining accuracy of the bearing rings but also disrupts the stability of the machining process. To avoid these problems, frequent timed shutdowns are required to clean the chips. This method increases the workload of operators and, due to frequent interruptions in the production process, significantly reduces the overall processing efficiency of the equipment. Utility Model Content

[0004] This invention addresses the shortcomings of the prior art by providing a multi-station synchronous turning machine tool for bearing rings that can conveniently and thoroughly remove chips, thereby enabling non-stop machining of the cutting machine.

[0005] A multi-station synchronous turning machine tool for bearing rings includes: a machining center, a loading assembly, and a tool assembly. The machining center is equipped with a machining section for centering, clamping, and fixing the workpiece and driving it to rotate at high speed. The machine tool also includes: a guide hopper fixedly connected to the machining center, which is correspondingly positioned directly below the machining section of the machining center and is inclined downwards; an electric slide rail fixedly connected to the machining center; a movable frame slidably connected to the electric slide rail, with the control end of the electric slide rail fixed to it to control its linear displacement; a support frame fixedly connected to the movable frame; a placement tray disposed on the support frame; and a collection box assembled and fixedly connected to the support frame for collecting chips, wherein the collection box has an inclined docking plate on the side near the machining section of the machining center.

[0006] Optionally, the placement tray is slidably connected to the support frame, and the machine tool further includes: a return spring fixedly connected between the placement tray and the support frame, wherein at least two sets are used and symmetrically arranged; and a vibration assembly disposed on the machining center for controlling the displacement of the placement tray.

[0007] Optionally, the vibration assembly includes: a cam rotatably connected to a support frame, the outer circle of which contacts the bottom of the placement disk and drives the placement disk to displace relative to the support frame through rotational compression; a gear fixedly connected to the end of the camshaft; and a rack fixedly connected to a corresponding position on the machining center, which meshes with the gear and whose length covers the effective stroke of the electric slide rail.

[0008] Optionally, the machine tool further includes a magnetic block fixedly connected to the placement tray, and the collection box is magnetically assembled and fixed to the placement tray by the magnetic block.

[0009] Optionally, the machine tool further includes a pad layer fixedly connected to the inner wall of the guide hopper to buffer the impact force when the bearing ring falls after processing.

[0010] Optionally, the machine tool further includes a protective frame fixedly connected to the placement plate, which covers the gears and rack.

[0011] The beneficial effects of this utility model are as follows: By adopting a structure that combines a connecting plate for guiding flow with a collection box for centralized collection, this utility model achieves comprehensive chip collection. Subsequent cleaning only requires disassembling the collection box, significantly improving the ease of operation of this utility model. The method of collecting chips with a collection box reduces the proportion of non-processing time, effectively extends the chip cleaning cycle time, greatly reduces the impact of chip handling operations on the processing rhythm of this utility model, and improves the overall processing efficiency of bearing rings.

[0012] This invention eliminates the chip repose angle through high-frequency vibration, preventing chips from forming "pointed accumulation" in the collection box, making the actual capacity of the collection box close to the rated volume, increasing the chip collection capacity per collection, and further extending the chip cleaning cycle time.

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0018] Example: A multi-station synchronous turning machine tool for bearing rings, such as Figure 1 As shown, it includes: a machining center 1, the main body of which is equipped with a machining section for centering, clamping and fixing workpieces and driving the workpieces to rotate at high speed; a loading assembly 2 fixedly installed on the side of the machining center 1, which adopts a multi-axis robotic arm structure in conjunction with a hopper that can only load workpieces one at a time, to realize the sequential gripping and positioning of workpieces, and to accurately transport the workpieces to the machining section of the machining center 1 for clamping and fixing; and a tool assembly 3 fixedly installed on the front side of the machining center 1, which is equipped with a double tool post assembly. The tool post contacts the surface of the high-speed rotating workpiece to realize the synchronous machining of bearing rings at two points. The position of the tool post is adjustable.

[0019] like Figures 1-3 As shown, the machine tool also includes: a guide hopper 6 fixedly installed on the machining center 1, which is correspondingly located directly below the machining section and is inclined downwards; a pad 15 fixedly installed on the inner wall of the guide hopper 6 by adhesive bonding, made of elastic material, used to buffer the impact force when the bearing ring falls after machining, and to avoid damage to the surface of the bearing ring; an electric slide rail 4 fixedly installed on the machining center 1; a movable frame 5 slidably installed on the electric slide rail 4, with the control end of the electric slide rail 4 fixed thereto to control its linear displacement; a support frame 7 fixedly installed on the movable frame 5; a placement tray 8 set on the support frame 7; a collection box 9 assembled and fixedly installed on the support frame 7, which is used to collect chips, and an inclined docking plate 901 is provided on the side of the collection box 9 near the machining section of the machining center 1; and a magnetic block 14 fixedly installed on the placement tray 8, with the collection box 9 magnetically assembled and fixed to the placement tray 8 by the magnetic block 14.

[0020] Workpieces are batch-loaded into the hopper of the feeding assembly 2, which automatically feeds each workpiece one by one. Then, the machining center 1, in conjunction with the tool assembly 3, processes the bearing rings one by one. During the processing, the chips generated fall under the action of gravity and are guided by the inclined docking plate 901 of the collection box 9, falling precisely into the collection box 9 to achieve comprehensive chip collection. After a single bearing ring is processed, the electric slide rail 4 controls the movement of the collection box 9, moving it away from the machining section, so that the docking plate 901 is removed from the area directly below the machining section. Then, the machining section releases the bearing ring, allowing it to fall freely into the guide hopper 6 below and slide out along the line, achieving automatic unloading. After unloading, the feeding assembly 2 feeds the next workpiece, and the electric slide rail 4 drives the collection box 9 to return to its original position, moving the docking plate 901 back to the area directly below the machining section. After the new workpiece is clamped, the next processing cycle begins.

[0021] This machine tool adopts a structure that combines a connecting plate 901 for guiding the flow with a collection box 9 for centralized collection, achieving comprehensive chip collection. Subsequent cleaning only requires disassembling the collection box 9, significantly improving the ease of operation of this machine tool. The chip collection method of this machine tool using the collection box 9 will reduce the proportion of non-processing time, effectively extend the chip cleaning cycle time, greatly reduce the impact of chip handling operations on the processing rhythm of this machine tool, and improve the overall processing efficiency of this machine tool for bearing rings.

[0022] like Figure 1 and Figure 3 As shown, the placement tray 8 is slidably mounted on the support frame 7. The machine tool also includes: a return spring 10 fixedly mounted between the placement tray 8 and the support frame 7, which is arranged in two sets symmetrically; a vibration component set on the machining center 1 for controlling the displacement of the placement tray 8 to generate a vibration effect, which includes: a cam 11 rotatably mounted on the support frame 7, whose outer circle contacts the bottom of the placement tray 8, and will drive the placement tray 8 to generate displacement relative to the support frame 7 by rotation and compression; a gear 12 fixedly mounted on the end of the shaft of the cam 11; and a rack 13 fixedly mounted on the corresponding position of the machining center 1, which meshes with the gear 12, and whose length covers the effective stroke of the electric slide rail 4.

[0023] like Figure 1 As shown, the machine tool also includes a protective frame 16 fixedly installed on the placement plate 8, which covers the gear 12 and rack 13 to prevent the meshing accuracy from being damaged due to the intrusion of impurities, and to prevent personnel from accidentally touching it.

[0024] As the collection box 9 moves with the moving frame 5, the gear 12 will roll relative to the rack 13, which will be converted into the rotational motion of the gear 12 and the cam 11 fixed on the same axis. This will cause the cam 11 to press the placement plate 8 to move against the elastic force of the return spring 10. The return spring 10 will then reset the placement plate 8. Under the cyclic action, high-frequency vibration control of the placement plate 8 is achieved. When the collection box 9 vibrates synchronously with the placement plate 8, the chips accumulated inside overcome the friction between the particles under the action of vibration, avoiding the repose angle phenomenon formed by the natural accumulation of chips.

[0025] This machine tool eliminates the chip repose angle through high-frequency vibration, preventing chips from forming "peaked accumulation" in the collection box 9, making the actual capacity of the collection box 9 close to the rated volume, increasing the chip collection capacity of the collection box 9 per cycle, and further extending the chip cleaning cycle time.

[0026] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
