Description

Technical Field

[0001] This utility model relates to the field of workpiece fixing device technology, and more specifically, to a workpiece fixing mechanism for a CNC lathe. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] CNC machine tools automatically process parts according to a pre-programmed machining program. The machining process route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions of the parts are written into a machining program sheet according to the instruction codes and program format specified by the CNC machine tool. The contents of this program sheet are then recorded on the control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to process the parts.

[0004] Existing CNC machine tools have difficulty fixing and positioning concave plates. Fixing them by clamping from both sides can easily cause deformation of the plates, rendering them unusable after processing and hindering production operations. Utility Model Content

The two mounting brackets 5 are fixedly connected to the bottom surface of the display panel 2, the bidirectional threaded rod 6 is rotatably connected between the outer walls of one side of the two mounting brackets 5, the mounting guide rail 8 is fixedly connected to the bottom surface of the display panel 2, the two movable brackets 9 are threadedly fitted onto the outer wall of the bidirectional threaded rod 6, the two top mounting seats 10 are detachably connected to the top surface of the corresponding movable bracket 9, and the two side mating plates 11 are detachably connected to the outer wall of one side of the corresponding top mounting seat 10.

[0028] In a specific embodiment of this utility model, the device is fixed inside a CNC lathe by a fixed base 1, and the display plate 2 is installed on the fixed base 1. The movable frame 9 is moved by rotating the bidirectional threaded rod 6. Under the restriction of the limiting rod 7 and the mounting guide rail 8, the movable frame 9 will move in both directions, and drive the top mounting seat 10 to move. The top mounting seat 10 is used to install and fix the side mating plate 11. The side mounting plate is used to adapt to the concave plate, that is, the two sides of the side mating plate 11 and the inner wall of the concave plate are mated to fix it. The concave plate is installed and removed by sliding back and forth. The side mating plate 11 is adjusted according to the different concave plates. When dealing with ordinary plates, the side mating plate 11 can be installed on the other side of the top mounting seat 10. When fixing and adapting the concave plate, the normal fixing effect will not be affected, which is conducive to processing operations.

[0029] Specifically, the top surface of the display panel 2 is provided with two sets of mating grooves 12, each set of mating grooves 12 has two grooves, and each set of mating grooves 12 is mated with the corresponding movable frame 9.

[0030] In this embodiment, the movable frame 9 is accommodated by the mating groove 12, allowing it to move laterally.

[0031] Specifically, a limiting rod 7 is fixedly connected between the outer walls of one side of the two mounting brackets 5, and the limiting rod 7 moves through the two movable brackets 9.

[0032] In this embodiment, the movable frame 9 is restricted by the limiting rod 7 to prevent it from rotating or shifting under the drive of the bidirectional threaded rod 6.

[0033] Specifically, the top surfaces of both movable frames 9 are provided with guide grooves, and both guide grooves slide in conjunction with the mounting rails 8.

[0034] In this embodiment, the installation and positioning are achieved by using the mounting rail 8 and the guide groove, and the movement is restricted.

[0035] Specifically, one of the mounting brackets 5 has a sub-rod rotatably connected to one side of its outer wall, and one end of the sub-rod is fixedly connected to one end of the bidirectional threaded rod 6.

[0036] In this embodiment, the bidirectional threaded rod 6 is extended by the sub-rod, allowing the operator to adjust and modify the bidirectional threaded rod 6 from the outside.

[0037] Specifically, the bottom surface of the fixed base 1 has two discharge slots 3, and the bottom surface of the fixed base 1 is fixedly connected with multiple fixing rods 4.

[0038] In this embodiment, the waste material from processing is discharged through the discharge chute 3, and the fixing rod 4 is used to assist in the installation and fixation of the fixing base 1.

[0039] Working principle: The device is fixed inside the CNC lathe via the fixed base 1, and the display plate 2 is installed on the fixed base 1. The movable frame 9 is moved by rotating the bidirectional threaded rod 6. Under the restriction of the limiting rod 7 and the mounting guide rail 8, the movable frame 9 will move in both directions, causing the top mounting seat 10 to move. The top mounting seat 10 is used to install and fix the side mating plate 11. The side mounting plate is used to adapt to the concave plate, that is, the two sides of the side mating plate 11 mate with the inner wall of the concave plate to fix it. The concave plate is installed and removed by sliding back and forth. The side mating plate 11 is adjusted according to the different concave plates. When dealing with ordinary plates, the side mating plate 11 can be installed on the other side of the top mounting seat 10. When fixing and adapting the concave plate, it will not affect the normal fixing effect, which is conducive to processing operations.

[0040] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
