Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool feeding technology, specifically a material pushing mechanism for a CNC machine tool and a processing machine tool. Background Technology

[0002] CNC machine tools, short for Computer Numerical Control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] For example, the publication number is CN215146391U, the publication date is December 14, 2021, and the title is "An Automatic Feeding Device for Slender Round Shafts". It includes a base plate, a longitudinally distributed support plate fixed to the rear top surface of the base plate, a feeding bin fixed to the support plate, and a guide slide plate connected to the outer wall of the feeding bin's port. A pushing assembly is also installed on the top surface of the base plate; a lower slide plate is also installed on the top surface of the base plate, and an upper slide plate is installed on the top surface of the lower slide plate; a blocking cylinder is fixed to the bottom surface of the guide slide plate, and the piston rod of the blocking cylinder passes through the guide slide plate. This automatic feeding device for slender round shafts utilizes the pushing assembly, the feeding bin, and the guide slide plate to automatically feed slender round shafts. The upper slide plate, lower slide plate, and support plate then transport the slender round shafts to a designated position for use in the next automated process, creating conditions for automated production and greatly improving the efficiency of automated processing.

[0004] In existing technologies, such as those containing the aforementioned patents, when feeding slender rods, the slender rods are usually fed by simply moving them laterally. However, there is still a certain distance between the processing station and the moved slender rod, so the slender rod needs to be pushed further to reach the processing station.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material pushing mechanism for a CNC machine tool, comprising:

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-6 The present invention provides a material pushing mechanism for a CNC machine tool, comprising: a frame 1; and a pushing mechanism 2, which includes a material pushing plate 21 fixedly connected to the frame 1, a pushing groove 22 provided on the pushing plate 21, a turntable 23 rotatably connected to the frame 1, a pushing block 24 slidably connected in the pushing groove 22, and a connecting rod 25 rotatably connected between the pushing block 24 and the turntable 23.

[0026] Specifically, the connecting rod 25 is eccentrically rotatably connected on the turntable 23.

[0027] As the turntable 23 rotates, the connecting rod 25 drives the pusher block 24 to reciprocate linearly within the pusher groove 22, thereby pushing the slender rod workpiece.

[0028] In this embodiment, a drive source (not shown in the figure) is also included. The drive source is a motor, and the output end of the drive source is fixedly connected to the turntable 23.

[0029] The feeding mechanism 3 is used to move slender rod workpieces into the pusher groove 22. It includes a fixed frame 31 fixedly connected to the frame 1, a lifting plate 32 vertically slidably connected to the fixed frame 31, a reciprocating screw 34 rotatably connected to the frame 1, the reciprocating screw 34 being screwed to the lifting plate 32, a rotating shaft 35 rotatably connected to the lifting plate 32, an elastic element being provided between the rotating shaft 35 and the lifting plate 32, support plates 36 fixedly connected to both ends of the rotating shaft 35, an abutting rod 37 fixedly connected between the two support plates 36, a discharge plate 38 fixedly connected to the pusher plate 21, and a first abutting groove 381 that abuts against the abutting rod 37 on the discharge plate 38.

[0030] Specifically, the elastic element is a spring; in the initial state, due to the elastic force of the elastic element, the support plate 36 is driven to be in a horizontal state; after the support plate 36 abuts against the first abutting groove 381, if the lifting plate 32 continues to move vertically upward, it will drive the rotating shaft 35 to rotate on the lifting plate 32 in the first direction, so that the end of the support plate 36 where the abutting rod 37 is located is lower than the end of the rotating shaft 35. Thus, after tilting, it is convenient for the slender rod workpiece to roll from the support plate 36 into the pushing groove 22.

[0031] Specifically, the connection between the fixed frame 31 and the slider 33 is as follows: a vertical groove 311 is provided on the fixed frame 31, and a slider 33 is fixedly connected to the lifting plate 32, and the slider 33 is slidably connected in the vertical groove 311.

[0032] It also includes a linkage mechanism 4, which is used to transmit the power of the turntable 23 to the reciprocating screw 34. The mechanism includes a first pulley 41 fixedly connected to the turntable 23, a second pulley 42 fixedly connected to the reciprocating screw 34, and a belt 43 between the first pulley 41 and the second pulley 42.

[0033] In this embodiment, a feeding mechanism 5 is also included, which includes a rotating rod 51 rotatably connected to the frame 1. One end of the rotating rod 51 is provided with a second abutting groove 511 that abuts against the abutting rod 37, and the other end of the rotating rod 51 is fixedly connected to a semi-circular plate 52.

[0034] As the slider 33 descends vertically, the abutting rod 37 abuts against the second abutting groove 511, causing the rotating rod 51 to rotate. This causes one end of the semicircular plate 52 to rotate upward and the other end of the second abutting groove 511 to rotate downward, so that the slender rod workpiece placed on the semicircular plate 52 can roll down onto the support plate 36, facilitating the subsequent conveying of the slender rod workpiece by the support plate 36.

[0035] The width of the rotating rod 51 can be set wider; the illustration is for illustrative purposes only, to prevent the slender rod workpiece from accidentally falling off the rotating rod 51 when it rolls.

[0036] In this embodiment, a material rack (not shown in the figure) is also included. Multiple slender rod workpieces are placed on the material rack. Whenever one end of the semicircular plate 52 of the rotating rod 51 rotates to the lowest point, the slender rod workpiece at the very end of the material rack will roll onto the semicircular plate 52.

[0037] In another embodiment, the unloading mechanism 5 may be omitted, and the slender rod workpiece may be placed directly on the support plate 36 by a robotic arm.

[0038] The processing machine tool includes the material pushing mechanism of the aforementioned CNC machine tool.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
