Description

Technical Field

[0001] This application relates to the field of chamfering machines, and particularly to a cutting device for a chamfering machine. Background Art

[0002] A chamfering machine is a tool used to create chamfers or bevels (i.e., bevel cuts on the edges) at the edges or corners of workpieces. Chamfering is an important step in the manufacturing and processing processes, commonly used to remove sharp edges, improve the appearance of components, or prepare for further processing. A chamfering machine can process the sharp edges of workpieces into bevel angles or rounded corners, thereby reducing the sharpness of the edges and avoiding scratches or other safety hazards.

[0003] The chamfering machine mainly cuts and chamfers workpieces through chamfering tools, forming bevel surfaces or rounded corners with specific angles at the edges of the workpieces. However, when chamfering different workpieces, the workpieces need to be repeatedly picked up and placed at the processing position, making the chamfering of workpieces time-consuming and laborious, reducing the continuous chamfering processing efficiency of the chamfering machine, and causing the workpieces to consume a long time during chamfering.

[0004] In view of the above-related technologies, the inventor believes that there are defects in the inconvenient repeated feeding operation of workpieces when the chamfering machine processes workpieces. Therefore, a cutting device for a chamfering machine is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problem of inconvenient repeated feeding operation of workpieces when the chamfering machine processes workpieces, this application provides a cutting device for a chamfering machine.

[0006] The cutting device for a chamfering machine provided by this application adopts the following technical solutions:

[0007] A cutting device for a chamfering machine includes an operating table. Chamfering devices are symmetrically arranged on the upper surface of the operating table. A chamfering tool is installed at the output end of one side of the chamfering device. Fixed plates are symmetrically welded on the upper surface of the operating table between the two chamfering devices. A support table is fixedly connected to the middle of the top of the fixed plate. Connecting rotating rods are rotatably installed at the front and rear ends of one side of the fixed plate. An activity bracket is rotatably installed between the two left and right symmetric connecting rotating rods. A plurality of placement grooves are formed on the upper surface of the activity bracket. The rotating shaft of the connecting rotating rod on one side of a single fixed plate extends outside the fixed plate and is installed with a pulley. A connecting belt is sleeved on the outer surface of the pulley. A first motor is installed in the middle of one side of a single pulley. A limiting mechanism is further provided above the operating table for fixing the workpiece inside the support table.

[0008] Preferably, the limiting mechanism includes a support plate fixedly installed at the top between two chamfering devices. A second motor is installed in the middle of one end of the support plate. The output end of the second motor passes through the support plate and is equipped with a movable disc. A fixed lever is welded to the edge of one end of the movable disc. A movable sleeve is movably installed on the outer surface of the fixed lever. Limiting cards are welded to both sides of the bottom end of the movable sleeve.

[0009] Preferably, support rods are fixedly installed at both the front and rear ends of the upper surface of the support table. Through holes are formed through both the front and rear ends of the limiting card. The outer diameter of the support rod is smaller than the inner diameter of the through hole. The limiting card is movably sleeved on the outer surface of the support rod, and the support rod and the limiting card are mutually engaged.

[0010] Preferably, grooves are formed in the middle of the top end of the support table and the middle of the bottom end of the limiting card, and the grooves inside the support table and the limiting card are aligned vertically.

[0011] Preferably, a guiding groove is formed through the top of the movable sleeve. The outer diameter of the fixed lever is smaller than the distance between the upper and lower ends of the inner wall of the guiding groove. One side of the outer surface of the fixed lever is located inside the guiding groove, and the fixed lever and the movable sleeve are mutually coupled.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By placing a number of workpieces in the placement grooves on the upper surface of the movable bracket, the rotating pulley drives the connecting rotating rod to move, and then conveys the workpieces on the upper surface of the movable bracket to the support table. At the same time, the rotation of the movable disc and the fixed lever drives the movable sleeve and the limiting card to move up and down, so that the limiting card cooperates with the support table to limit and fix the workpieces during chamfering, and the chamfering device cooperates with the chamfering tool to act on the workpieces for chamfering; compared with the prior art, this solution has the effect of facilitating the convenient feeding of the workpieces during chamfering, improving the continuous chamfering processing efficiency of the workpieces, and solving the problem that it is time-consuming and laborious to feed the workpieces.

[0022] Refer to Figure 3 and Figure 4, the limiting mechanism includes a support plate 13, which is fixedly installed at the top between two chamfering devices 2. In the middle of one end of the support plate 13, a second motor 14 is installed. The output end of the second motor 14 passes through the support plate 13 and is equipped with a movable disc 15. A fixed lever 16 is welded to the edge of one end of the movable disc 15. An activity sleeve 17 is movably installed on the outer surface of the fixed lever 16. Limiting cards 18 are welded to both sides of the bottom end of the activity sleeve 17. A guiding groove is opened through the top of the activity sleeve 17. The outer diameter of the fixed lever 16 is smaller than the distance between the upper and lower ends of the inner wall of the guiding groove. One side of the outer surface of the fixed lever 16 is located inside the guiding groove, and the fixed lever 16 and the activity sleeve 17 are coupled with each other.

[0023] By starting the second motor 14 to drive the movable disc 15 to rotate, the rotation of the movable disc 15 and the fixed lever 16 drives the activity sleeve 17 and the limiting cards 18 to move up and down.
