Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, and in particular to a machining auxiliary support for milling machines. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the milling cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, and more.

[0003] Currently, the length of existing milling machine worktables is often limited, making it impossible to effectively support both ends of workpieces that exceed the length of the worktable, resulting in poor stability during workpiece processing. In order to better realize the function of conveniently providing auxiliary support for the workpiece to be processed and improve the core technology competitiveness, this application proposes a new implementation scheme for a machining auxiliary support for milling machines that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problem of effectively supporting and fixing the two ends of a workpiece that exceeds the length of the worktable, and to propose a machining auxiliary support for milling machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A machining auxiliary support for a milling machine includes a worktable. A connecting seat is fixedly connected to the bottom of the worktable. The connecting seat has a cavity. A motor is fixedly connected to the bottom inner wall of the cavity. A gear is fixedly connected to the output end of the motor. Guide tubes are fixedly inserted into both ends of the connecting seat. A sliding rod is slidably connected to one end of the guide tube. A toothed groove is provided on one side of the sliding rod, and the toothed groove meshes with the gear. A rectangular groove is provided on one side of the guide tube. A connecting block is slidably connected in the rectangular groove. One end of the connecting block is fixedly connected to one side of the sliding rod. A support block is fixedly connected to the top of the connecting block. A mounting plate is fixedly connected to the top of the support block.

[0007] Furthermore, the top of the workbench is provided with multiple T-shaped blocks.

[0008] Furthermore, both ends of the connecting seat are fixedly connected to support rods, and the outer walls of the support rods and the outer walls of the guide tubes are slidably fitted with slip rings. Both ends of the connecting block are fixedly connected to the two slip rings respectively.

[0009] Furthermore, a limit plate is fixedly connected to one end of the guide tube and one end of the support rod.

[0010] Furthermore, the top of the mounting plate is provided with multiple mounting holes, and fixing bolts are threaded into the mounting holes.

[0011] Furthermore, a control panel is fixedly connected to one side of the connecting base, and the control panel is electrically connected to the motor.

[0012] Furthermore, the gear is located between two toothed grooves.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the motor and the meshing of the gear and tooth groove, the sliding rod moves in the guide tube, thereby driving the mounting plate and the clamps on it to move. Then, the distance between the clamps of the two mounting plates is adjusted according to the length of the workpiece to support both ends of the workpiece, thereby improving the stability of the workpiece during processing.

[0015] 2. The movement of the mounting plate is guided by the slip ring moving along the guide tube and support rod, thereby improving the stability of the adjustment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A machining auxiliary support for a milling machine includes a worktable 1, and a connecting seat 3 is fixed to the bottom of the worktable 1 by bolts. The connecting seat 3 can be connected to a support leg.

[0023] The connecting seat 3 has a cavity 4 inside. The bottom inner wall of the cavity 4 is fixed with a motor 6 by bolts. The motor 6 can be a motor with a self-locking function, such as a geared motor. The output end of the motor 6 is keyed with a gear 7.

[0024] Guide tubes 9 are fixedly inserted diagonally at both ends of the connecting seat 3. A sliding rod 11 is slidably connected to one end of the guide tube 9. A toothed groove 12 is provided on one side of the sliding rod 11. A gear 7 is located between the two toothed grooves 12. The toothed groove 12 and the gear 7 are tightly meshed. A rectangular groove 10 is provided on one side of the guide tube 9. A connecting block 14 is slidably connected in the rectangular groove 10. One end of the connecting block 14 is fixedly connected to one side of the sliding rod 11. A support block 15 is welded to the top of the connecting block 14. The rectangular groove 10 and the connecting block 14 prevent the sliding rod 11 from rotating in the guide tube 9.

[0025] Both ends of the connecting seat 3 are welded with support rods 8. The outer walls of the support rods 8 and the outer walls of the guide tubes 9 are slidably fitted with slip rings 13. Both ends of the connecting block 14 are fixedly connected to the two slip rings 13 respectively. The inner walls of the slip rings 13, the outer walls of the guide tubes 9 and the outer walls of the support rods 8 are all smooth. Lubricating oil can also be applied to the connection to ensure smoothness, so that the slip rings 13 can move along the guide tubes 9 and the support rods 8, thereby guiding the movement of the mounting plate 16 and improving the stability of the adjustment.

[0026] The top of the support block 15 is fixed with a mounting plate 16 by bolts. The top of the mounting plate 16 is provided with multiple mounting holes 17. The mounting holes 17 are internally threaded with fixing bolts for directly fixing the workpiece or installing external movable clamps.

[0027] Driven by the motor 6 and engaged by the gear 7 and the toothed groove 12, the sliding rod 11 moves within the guide tube 9, thereby moving the mounting plate 16 and the clamps on it, and adjusting the distance between the clamps of the two mounting plates 16 according to the length of the workpiece.

[0028] The top of the worktable 1 is provided with multiple T-blocks 2, and the multiple T-blocks 2 form a convex groove structure to provide clearance space for processing. External moving fixtures can also be installed in the convex groove to clamp the workpiece. For example, the fixtures can be selected from three-jaw self-centering chucks, four-jaw single-action chucks, spindle-type fixtures, etc. that are compatible with the T-blocks 2.

[0029] Limiting plates 18 are welded to one end of the guide tube 9 and one end of the support rod 8 to limit the movement of the slip ring 13;

[0030] A control panel 5 is fixed to one side of the connector 3 by bolts, and the control panel 5 is electrically connected to the motor 6 by wires.

[0031] The working principle of this embodiment is as follows: In use, firstly, according to the volume of the workpiece, the motor 6 is started by controlling the control panel 5. Under the drive of the motor 6, the gear 7 rotates. Then, under the action of the gear 7 meshing with the toothed groove 12, the sliding rod 11 moves in the guide tube 9, thereby driving the mounting plate 16 and the clamps on it to move. Then, the distance between the clamps of the two mounting plates 16 is adjusted according to the length of the workpiece. Then, the two ends of the workpiece are placed on the mounting plate 16 and fixed. Then, the milling machine is used for processing.

[0032] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
