Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool loading technology, and more specifically, to a CNC machine tool loading mechanism. Background Technology

[0002] A CNC machine tool feeding mechanism is a device that automatically feeds blanks or semi-finished products into the processing area of ​​a CNC machine tool. These include vibratory feeder feeding mechanisms, gantry robot feeding mechanisms, articulated robot feeding mechanisms, guide rail feeding mechanisms, and conveyors. The working principle of the vibratory feeder feeding mechanism is as follows: parts are poured into the hopper in batches. Through electromagnetic vibration, the parts move upwards in an orderly manner along a spiral track within the feeder. During this movement, directional devices such as notches, grooves, and air blowing are used to adjust the parts to a uniform posture. The parts exiting the vibratory feeder enter a linear vibratory feeder, which smoothly transports them to the designated position at the machine tool entrance. Vibratory feeder feeding machines can continuously supply materials and are suitable for mass production.

[0003] Existing CNC machine tool feeding mechanisms, such as vibratory feeder feeding mechanisms, can transport short bars. However, when transporting bars, large-diameter defective products are easily mixed in with bars of the same diameter in the same batch. When the bars are transferred in the curved material channel, blockages are easily caused, making it impossible to remove them quickly. Manual picking is required. In view of this, we propose a CNC machine tool feeding mechanism. Utility Model Content

The main straight chute 1041, the branch straight chute 1042 and the branch inclined chute 1043 form a "Y" shape. The main straight chute 1041 directly receives the bar stock discharged from the vibratory plate body 102. The branch straight chute 1042 is smoothly connected to the main straight chute 1041 and is used to guide the bar stock with a smaller diameter. The branch oblique chute 1043 forms a certain angle with the main straight chute 1041, together forming a "Y"-shaped fork, which, together with the arc plate 1044 extending into it, is used to guide the bar stock with a larger diameter.

[0019] In another embodiment of the present invention, a material transfer component 2 is provided at the discharge port of the straight chute 1042, and a conveyor belt 3 is provided at the discharge port of the material transfer component 2. Conveyor belt 3 receives qualified bar stock from material transfer component 2 and transports it to the loading station of CNC machine tool.

[0020] In another embodiment of the present invention, the material transfer assembly 2 includes a limiting piece 204 fixed on the outer wall of the discharge port of the straight chute 1042 and a fixed inclined chute 201 provided at the feed end of the conveyor belt 3. A movable inclined chute 202 is provided above the fixed inclined chute 201 and can cooperate with it. The movable inclined chute 202 can be driven by a stepper motor 203 to rotate to be limited by the limiting piece 204 and cooperate with the discharge port of the straight chute 1042.

[0021] The stepper motor 203 can drive the movable inclined slide 202 to rotate. The limiting piece 204 is fixed on the outside of the discharge port of the straight slide 1042 and is used to limit the movable inclined slide 202 when it rotates to the receiving position, so that it can complete the docking with the discharge port of the straight slide 1042.

[0022] A material box 4 is provided below the discharge port of the inclined chute 1043 to collect the large-diameter unqualified bar stock that has been sorted out; Arc plate 1044 is slidably connected to the inner wall of inclined slide groove 1043. The inner arc end of arc plate 1044 faces the discharge port of vibratory plate body 102. A lead screw assembly 1045 is provided on the outer wall of arc plate 1044 and can be driven by self-locking drive assembly 1046 through lead screw assembly 1045.

[0023] Arc plate 1044 is a baffle with an arc-shaped inner side, the inner arc surface of which faces the direction of the bar stock, and it is slidably installed at the bifurcation point; In another embodiment of the present invention, the lead screw assembly 1045 includes a limiting shell and a lead screw rotatably connected within the limiting shell. A lead screw sleeve is threadedly connected to the outer wall of the lead screw, and an arc plate 1044 is connected to the outer wall of the lead screw sleeve via a connecting rod.

[0024] The lead screw assembly 1045 adopts existing products on the market and consists of a lead screw, a lead screw sleeve and a limiting shell. The lead screw sleeve is connected to the arc plate 1044 through a connecting rod, which can convert the rotational motion of the lead screw into the linear motion of the arc plate 1044.

[0025] In another embodiment of the present invention, the self-locking drive assembly 1046 includes a worm gear fixed to the end of the lead screw assembly 1045, and a worm is engaged with the outer wall of the worm gear, which can be driven by an electric motor.

[0026] The self-locking drive assembly 1046 is driven by a motor to drive a worm gear, which then meshes with a worm wheel installed at the end of the lead screw. The worm wheel and worm gear are self-locking, which can lock the arc plate 1044 after it is adjusted to the correct position to prevent it from shaking.

[0027] Working principle: This embodiment provides a loading mechanism for a CNC machine tool. When in use, it is powered by an external power source. The vibratory plate base 101 and the linear vibrator 103 are turned on by an external switch. The vibratory plate body 102, driven by the vibratory plate base 101, arranges the randomly piled bar stock in an orderly manner and feeds them one by one into the linear vibratory track 104 driven by the linear vibrator 103. The bar stock moves forward close to the outer edge of the inner side wall of the track. This is an existing product and technology on the market. The main straight chute 1041, the branch straight chute 1042, and the branch inclined chute 1043 form a "Y" shape. When the bar stock is conveyed to the "Y" shaped fork, the small-diameter bar stock, due to its smaller diameter, cannot contact the adjustable arc plate 1044 and will directly enter the branch straight chute 1042 along the original path. The large-diameter bar stock, due to its larger diameter, will contact the inner arc surface of the arc plate 1044 during the movement. Under the guidance of the arc surface and the action of inertia, the bar stock changes its trajectory, slides into the branch inclined chute 1043, and finally falls into the material box 4 below it for collection. The qualified small-diameter bar stock enters the straight slide 1042 and reaches the discharge port. The external power supply turns on the stepper motor 203 through the external switch. The stepper motor 203 drives the inclined slide 202 to rotate and transfer the bar stock to the conveyor belt 3. The conveyor belt 3 continuously feeds the bar stock to the CNC machine tool. When the diameter of the bar stock to be rejected changes, the lead screw assembly 1045 can be driven by the self-locking drive assembly 1046 to control the length of the arc plate 1044 extending into the bifurcation, so as to adapt to the sorting of bars with different diameters (the motors of the vibratory plate base 101, the linear vibrator 103, the stepper motor 203 and the self-locking drive assembly 1046 are all existing products and are all connected to an external power supply and an external switch).

[0028] 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.
