Description

Technical Field

[0001] The present invention belongs to the field, and specifically relates to a double-headed chamfering machine. Background Art

[0002] In the field of industrial manufacturing, chamfering is an important process for surface treatment of metal or non-metal workpieces. The purpose is to improve the surface quality and safety of products by removing burrs, sharp edges or corners on the edges of workpieces. However, the processing mode of traditional chamfering machines has significant limitations in terms of efficiency and accuracy, restricting the further improvement of production efficiency:

[0003] 1. Traditional chamfering machines generally adopt a single-station processing mode, that is, only a single workpiece is clamped and processed each time. In this mode, after the processing of one workpiece is completed, the workpiece needs to be replaced manually or by a manipulator, resulting in frequent workpiece switching and repeated positioning, significantly prolonging the production cycle.

[0004] 2. Some equipment attempts to improve efficiency by increasing the multi-station design, but in essence, it is still a simple superposition of single-station structures, and there is a lack of coordinated control mechanism between stations. For example, the clamping mechanisms and processing units of multiple independent stations need to be positioned and adjusted separately, and it is easy to cause poor quality consistency of workpieces due to mechanical errors or control delays of each station.

[0005] 3. Traditional chamfering processing usually adopts a compound motion mode of clamping mechanism rotation + tool linear movement. Specifically, after the workpiece is clamped, it rotates around a fixed axis, and the tool moves along a preset path (such as a straight line or a curve) to contact the surface of the workpiece to complete chamfering. In this processing method, the stroke of the tool is long, resulting in an increase in the time-consuming of a single processing. Especially when processing complex contours or large-sized workpieces, the efficiency problem is more prominent. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions.

[0007] A double-headed chamfering machine includes a base, on which a base seat is assembled, and on the base seat, an assembling mechanism and a processing mechanism are assembled. The assembling mechanism includes a two-axis moving component and an assembling component. The two-axis moving component is used to drive the assembling component to move in the YZ plane; the assembling component includes an assembling connecting plate, on which a main shaft and a driving motor are assembled. The driving motor is used to drive the main shaft to rotate; clamping seats for clamping workpieces are assembled at both ends of the main shaft. The processing mechanism includes an X-direction moving component and a processing component. The X-direction moving component is used to drive the processing component to move towards the clamping seat; there are two groups of processing mechanisms, and the two groups of processing mechanisms are symmetrically distributed about the main shaft.

[0008] Further, the two-axis moving assembly includes a Y-axis motor. The Y-axis motor is connected to a Y-axis moving lead screw. A sliding seat is assembled on the Y-axis moving lead screw. The sliding seat is assembled and connected to the base through a slide rail. The Y-axis motor makes the sliding seat move along the Y-axis by driving the rotation of the Y-axis moving lead screw. A Z-axis mounting frame is assembled on the sliding seat. A Z-axis motor is assembled on the Z-axis mounting frame. The Z-axis motor is connected to a Z-axis moving lead screw. An assembly connecting plate is assembled on the Z-axis moving lead screw. The assembly connecting plate is assembled and connected to the Z-axis mounting frame through a slide rail. The Z-axis motor makes the assembly connecting plate move along the Z-axis by driving the rotation of the Z-axis moving lead screw.

[0009] Further, an A-axis motor and an A-axis rotating assembly are also assembled on the sliding seat. The Z-axis mounting frame is assembled and connected to the A-axis rotating assembly. The A-axis motor is used to drive the A-axis rotating assembly to rotate around the Y-axis.

[0010] Further, the X-axis moving assembly includes an X-axis motor. The X-axis motor is connected to an X-axis moving lead screw. The processing assembly is assembled on the X-axis moving lead screw. The processing assembly is assembled and connected to the base through a slide rail. The X-axis motor makes the processing assembly move along the X-axis by driving the rotation of the X-axis moving lead screw.

[0011] Further, the processing assembly includes a processing seat. A cutter head and a processing motor are assembled on the processing seat. The cutter head is driven by the processing motor. A cutting tool for chamfering the workpiece is assembled on the cutter head.

[0012] Further, a loading and unloading mechanism is also included. The loading and unloading mechanism includes a truss. Two sets of loading and unloading assemblies are assembled on the truss. The two sets of loading and unloading assemblies perform loading and unloading on two sets of clamping seats respectively. The loading and unloading assembly includes a cross beam. The cross beam is assembled on the truss through a first moving module. A lifting frame is assembled on the cross beam through a second moving module. A clamping assembly is assembled on the lifting frame through a third moving module. The clamping assembly is used to load or unload the clamping seat.

[0013] Further, the clamping assembly includes a rotary cylinder. The rotary cylinder is connected to a mounting block. Two sets of clamping claws are assembled on the mounting block.

[0014] Further, a feeding mechanism is also included. The feeding mechanism includes a feeding frame and four trays placed on the feeding frame. The four trays are distributed in pairs to correspond to two sets of loading and unloading assemblies. Among the two trays corresponding to a single set of loading and unloading assemblies, one is a loading tray and the other is a blanking tray.

[0015] Further, a number of sliding seats are assembled on the feeding frame. A chute is provided on the sliding seat. The tray is placed on the sliding seat and can slide through the chute. A baffle is provided on one side of the sliding seat. A limiting member is assembled in the chute of the sliding seat. A limiting head that can only rotate in one direction is assembled on the limiting member. The baffle and the limiting head cooperate to limit the tray.

[0016] Compared with the prior art, the double-head chamfering machine provided by the present application has the following significant beneficial technical effects:

[0017] 1. Dual-station synchronous processing significantly improves production efficiency: The clamping seats at both ends of the spindle clamp two workpieces at the same time, and two sets of processing mechanisms are symmetrically distributed on both sides of the spindle to achieve synchronous processing of the two workpieces. This symmetrically distributed processing mechanism can complete the chamfering operation of two workpieces in the same processing cycle. Compared with the traditional single-station processing mode, the processing efficiency is directly doubled, while avoiding the time waste caused by switching workpieces or repeated positioning, greatly shortening the production cycle.

[0018] 2. The tool and the clamping seat are linked for processing, with high production efficiency and good processing consistency: The two-axis moving components of the assembly mechanism (Y-axis motor + Z-axis motor) realize high-precision movement of the assembly components in the YZ plane through the screw slide structure, ensuring that the positioning error of the workpiece before processing is extremely small, and can ensure that the processing path and feed speed of the two workpieces are consistent, thereby ensuring the consistency of the processing quality of the two workpieces. The Z-axis mounting frame is driven by the A-axis motor to rotate around the Y-axis, which can flexibly adjust the workpiece angle to meet different processing requirements.

[0019] 3. Fully automated loading and unloading and feeding to reduce manual dependence: The two sets of loading and unloading components on the truss can accurately grasp the workpiece and complete the loading and unloading actions through the three-axis moving module (X / Y / Z direction) and the clamping claw driven by the rotary cylinder. No manual intervention is required throughout the process, reducing efficiency fluctuations and safety hazards caused by manual operation. BRIEF DESCRIPTION OF THE DRAWINGS
