Description

Technical Field

[0001] The utility model relates to the technical field of shaft parts production, in particular to a supporting mechanism of a pneumatic marking machine for automobile shaft parts. Background Art

[0002] The pneumatic marking machine is a computer-controlled printing needle that moves along a certain trajectory in the X, Y two-dimensional plane. At the same time, the printing needle performs high-frequency impact movement under the action of compressed air, thereby printing a mark with a certain depth on the workpiece. At the same time, the marking machine is mainly used in automobile and motorcycle parts, instruments and meters, machinery, automobiles, signboards and other industries.

[0003] The existing pneumatic marking machines still have some shortcomings in actual use:

[0004] 1. When the existing pneumatic marking machine is marking the automotive shaft parts, when supporting the shaft parts, the distance between the two clamping plates is adjusted mainly by manually rotating the screw rod, so as to clamp and support the parts. The manual adjustment method is not only slow, but also difficult to control the clamping force, which is easy to cause wear to the parts.

[0005] 2. Although the existing support mechanism can clamp and support shaft parts, when encountering longer parts, it is only clamped and fixed by two clamping plates, the clamping force is low and the clamping is not stable enough. Utility Model Content

[0006] The purpose of the utility model is to solve the problems in the prior art that the manual adjustment method is not only slow, but also difficult to control the clamping force, which is easy to cause wear to parts. When encountering longer parts, they are clamped and fixed only by two clamping plates, the clamping force is low, and the clamping is not stable enough. A support mechanism for a pneumatic marking machine for automobile shaft parts is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The supporting mechanism of the pneumatic marking machine for automobile shaft parts comprises a workbench, the top of which is slidably provided with two sliding seats, and a clamping frame is fixedly connected to the sliding seat; it also comprises a sliding component, through which the distance between the two sliding seats can be adjusted; it also comprises two clamping components, and the two clamping components have the same structure, the two clamping components are respectively located in two clamping frames, and the distance between the two sliding seats can be adjusted, so that shaft parts of different lengths can be clamped by the two clamping components.

[0009] In a possible design, the sliding assembly includes a bidirectional screw rod rotatably connected to the workbench, two nuts are slidably connected to the workbench, and two sliding seats are respectively fixedly connected to the top of the two nuts, and the two nuts are respectively threadedly sleeved on the positive and negative threaded sections of the bidirectional screw rod. A driving motor is fixedly connected to the workbench, and the output shaft of the driving motor is fixedly sleeved with a second gear, and one end of the bidirectional screw rod is fixedly sleeved with a first gear, and the first gear and the second gear are meshed, and the distance between the two sliding seat brackets can be adjusted by driving the moving assembly.

[0010] Material toggling mechanism, its both sides respectively have the support of the support frame, and the support frame has the support frame and the support frame has a plurality of independently controlled members, and the independently controlled members have the plurality of independently controlled members.

[0011] In a possible design, an electric push rod is fixedly installed on the bottom inner wall of the sliding seat, and the output shaft of the electric push rod passes through the clamping frame and is fixedly connected to the bottom end of the supporting slide column. The support slide column can be pushed up and down in the clamping frame by the extension and retraction of the output shaft of the electric push rod, and the shaft parts can be clamped by the cooperation of the supporting slide column and the two clamping handles.

[0012] In a possible design, rollers are provided at the top and bottom of the clamping handle, the roller at the top can slide on the outer wall surface of the shaft part, and the roller at the bottom can slide on the surface of the guide block.

[0013] In a possible design, a support table is provided under the workbench, and the workbench is fixedly installed on the top of the support table. A marking machine is fixedly installed on the top of the support table. A controller is provided on the support table, and the drive motor, two electric push rods and the start and stop of the marking machine can be controlled respectively by the controller.

[0014] In the present application, the driving motor is started, and the output shaft of the driving motor drives the second gear to rotate, and then meshes with the first gear, thereby driving the bidirectional screw rod to rotate, and the bidirectional screw rod rotatably connected to the workbench drives the two nuts to slide in the workbench through its positive and negative threaded sections, and the tops of the two nuts are fixedly connected to the two sliding seats. Therefore, by rotating the bidirectional screw rod, the distance between the two sliding seats can be adjusted. When the distance between the two sliding seats is adjusted to a suitable position, the clamping assembly starts to work. Each clamping assembly includes two clamping handles rotatably connected to the clamping frame. When the output shaft of the electric push rod is extended and retracted, it pushes the supporting sliding column to move up and down in the clamping frame. At the same time, guide blocks are provided on both sides of the supporting sliding column. The two clamps The bottom of the holding handle slides on the surface of the guide block. As the supporting slide column moves up and down, the tops of the two clamping handles move closer to or farther away from each other, thereby clamping or releasing the shaft parts placed on the top of the supporting slide column. During the clamping process, the roller design of the clamping handle allows the roller at the top to slide on the outer wall surface of the shaft parts, while the roller at the bottom slides on the surface of the guide block, which helps to clamp the shaft parts more smoothly and accurately. When the shaft parts are stably clamped on the supporting mechanism, the pneumatic marking machine starts the marking operation. The entire operation process is controlled by a controller, which includes an electrical control cabinet, PLC, etc., which is responsible for monitoring and adjusting the working status of each component to ensure the accuracy and stability of the marking process.

This flexibility enables the same pneumatic marking machine to process shaft parts of various specifications, greatly improving the utilization rate and adaptability of the equipment;

[0017] In the utility model, the design of the clamping assembly enables shaft parts to be firmly clamped on the supporting mechanism. The shaft parts can be accurately clamped by the up and down movement of the supporting slide column and the mutual approach of the two clamping handles. The design of the roller not only reduces the friction, but also makes the clamping process more stable, thereby ensuring the stability and accuracy of the marking process. At the same time, the telescopic movement of the supporting slide column can drive the two clamping handles to clamp shaft parts of different sizes.

[0018] In the utility model, the distance between the two clamping components can be adjusted by the sliding component, and at the same time, not only shaft parts of different lengths but also shaft parts of different sizes can be clamped, and the application range is wider and more flexible.
