Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a CNC machining center with automatic chip removal function. Background Technology

[0002] CNC machining centers typically refer to precision machining using computer numerical control technology, including CNC lathes, CNC milling machines, and CNC boring machines. However, CNC machining centers also have certain limitations in use. Due to the low level of human intervention, real-time cleaning is not possible, which may cause debris generated during machining to accumulate on the table, affecting the positioning and machining accuracy to some extent.

[0003] In the prior art, according to announcement number CN119635395A, a CNC machining center with a table cleaning function is disclosed, relating to the field of CNC machine tool technology. The CNC machining center includes a machine tool, a drive unit, a chip removal device, and a collection device. The drive unit is connected to the machine tool, the drive unit and the chip removal device are connected by a transmission, the chip removal device is connected to the machine tool, the chip removal device and the collection device are connected by pipes, and the collection device is securely connected to the machine tool. The chip removal device sprays an arc-shaped liquid to blow away debris. By employing a computer numerical control system for high-precision and high-efficiency machining, the chip removal device collects the debris generated during machining, achieving automatic table cleaning. The collection device separates the debris, facilitating liquid recycling. During CNC machining, the chip removal device sprays liquid outwards, forming an arc-shaped surface, thereby attenuating the velocity of centrifugal debris during machining and preventing debris splashing.

[0004] However, while existing CNC machining equipment can effectively collect debris through the discharge hole, the collection box often uses a rectangular frame to collect the debris. This method is not very effective for the automatic discharge of debris under gravity, and the synchronous blowing and unblocking of debris on the inner wall of the discharge hole is not very efficient, which can easily cause blockages. Utility Model Content

[0005] The purpose of this invention is to provide a CNC machining center with automatic chip removal function, which can solve the problems mentioned in the background art, such as the low efficiency of automatic chip dropping under gravity and the poor synchronous blowing and unblocking of chips on the inner wall of the chip dropping hole during chip collection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a CNC machining center with automatic chip removal function, comprising a CNC machining equipment, a machining table inside the CNC machining equipment, a coolant spray pipe inside the CNC machining equipment, a material drop hole inside the CNC machining equipment, a material collection box fixedly connected to the bottom of the CNC machining equipment, a material discharge port fixedly connected to the bottom of the material collection box, an air supply pump on the outer wall of the CNC machining equipment, an air supply pipe fixedly connected to the outer wall of the air supply pump, one end of the air supply pipe being connected to a jet pipe rotatably connected to the inner wall of the material collection box via a rotary joint, a rotating shaft rotatably connected to the inner wall of the material collection box, and a spiral roller fixedly connected to the outer wall of the rotating shaft.

[0007] By adopting the above technical solution, when the debris is automatically collected by the collection box, the rotating shaft drives the spiral roller to rotate, which spirally attracts the debris from the discharge hole. With the outer wall of the collection box having a conical shape, the debris naturally slides to the center of the bottom of the groove under the action of gravity. If there is blockage on the surface of the discharge hole, the second motor is turned on, and the rotation of the threaded rod drives the threaded sliding tooth plate to slide along the inner wall of the fixed groove. This also drives the air jet pipe fixedly connected to the connecting gear to adjust the angle, achieving the effect of clearing the surface of the discharge hole and cleaning the surface of the spiral roller. This improves the chip removal efficiency of the CNC machining equipment and reduces blockage.

[0008] Preferably, the outer wall of the CNC machining equipment is provided with a coolant storage box, and the outer wall of the coolant storage box is fixedly connected to a delivery pipe that is fixedly connected to the outer wall of the coolant spray pipe.

[0009] Preferably, the material collection box is equipped with a first motor that is fixedly connected to one end of the rotating shaft.

[0010] Preferably, the outer wall profile of the spiral roller is a cone shape that is larger at the top and smaller at the bottom, and the bottom of the collection box is an inclined surface that slopes downward toward the material outlet.

[0011] Preferably, the outer wall of the CNC machining equipment is provided with a control box, and the outer wall of the control box is provided with a second motor, the output end of the second motor being fixedly connected to a threaded rod.

[0012] Preferably, the threaded rod is provided in two sets, and the two sets of threaded rods rotate in opposite directions.

[0013] Preferably, the outer wall of the threaded rod is threadedly connected to a threaded sliding toothed plate that is slidably connected to the inner wall of the control box, and the outer wall of the threaded sliding toothed plate is engaged with a connecting gear that is fixedly connected to one end of the jet pipe.

[0014] Preferably, a fixing groove is provided at the connection between the inner sidewall of the control box and the threaded sliding tooth plate.

[0015] Preferably, there are two sets of jet pipes, and the positions of the two sets of jet pipes are symmetrical about the central axis of the collection box.

[0016] Preferably, the spiral roller is positioned on the rotation path of the jet pipe.

[0017] The beneficial effects of this utility model are:

[0018] This invention, by incorporating a spiral roller and an air jet pipe, automatically collects debris via a collection box. The rotating shaft drives the spiral roller to rotate, drawing debris from the discharge hole in a spiral motion. The conical shape of the collection box's outer wall allows the debris to slide naturally towards the center of the groove under gravity. If the discharge hole is clogged, a second motor is activated, rotating a threaded rod to slide a threaded sliding toothed plate along the inner wall of the fixed groove. This also adjusts the angle of the air jet pipe, which is fixedly connected to a connecting gear. This achieves the effect of clearing the discharge hole surface with air and cleaning the spiral roller surface with debris, improving the chip removal efficiency of CNC machining equipment and reducing clogging.

[0028] The outer wall of the CNC machining equipment 1 is provided with a coolant storage box 7. The outer wall of the coolant storage box 7 is fixedly connected to a delivery pipe 8 which is fixedly connected to the outer wall of the coolant spray pipe 3. This facilitates the convenient delivery of coolant through the delivery pipe 8.

[0029] The material collection box 4 is equipped with a first motor 14 that is fixedly connected to one end of the rotating shaft 15. The spiral roller 16 forms a rotating structure with the first motor 14 and the rotating shaft 15, which is beneficial to the driving of the first motor 14. Through the connection of the rotating shaft 15, the spiral roller 16 is driven to rotate, so as to achieve the effect of efficient collection of debris.

[0030] Among them, the outer wall contour of the spiral roller 16 is a cone shape with a larger upper part and a smaller lower part, and the bottom of the trough of the collection box 4 is an inclined surface that slopes downward to the material outlet 5. This facilitates the easy rolling of debris under gravity through the inclined surface of the bottom of the trough of the collection box 4.

[0031] The outer wall of the CNC machining equipment 1 is equipped with a control box 6, and the outer wall of the control box 6 is equipped with a second motor 17. The output end of the second motor 17 is fixedly connected to a threaded rod 18. The threaded rod 18 forms a rotating structure with the control box 6 through the second motor 17, which is conducive to driving the second motor 17 to drive the threaded rod 18 to rotate along the inner wall of the control box 6, thereby achieving the effect of driving the threaded sliding tooth plate 19 to slide easily.

[0032] The threaded rod 18 is provided in two sets, and the two sets of threaded rods 18 rotate in opposite directions. This is beneficial to achieve the effect of driving the two sets of threaded sliding tooth plates 19 to slide relative to each other by setting two sets of threaded rods 18 with opposite rotation directions.

[0033] The outer wall of the threaded rod 18 is threadedly connected to a threaded sliding toothed plate 19 that is slidably connected to the inner wall of the control box 6. The outer wall of the threaded sliding toothed plate 19 is engaged with a connecting gear 9 that is fixedly connected to one end of the jet pipe 12. The connecting gear 9 forms a rotating structure with the control box 6 through the threaded sliding toothed plate 19, which facilitates the sliding of the threaded sliding toothed plate 19 and drives the connecting gear 9 to rotate along the inner side wall of the control box 6, so as to achieve the effect of convenient adjustment of the jet pipe 12's operating angle.

[0034] The inner wall of the control box 6 is provided with a fixing groove 20 at the connection between it and the threaded sliding tooth plate 19. This fixing groove 20 helps to limit the sliding of the threaded sliding tooth plate 19.

[0035] Among them, there are two sets of air jet pipes 12. The positions of the two sets of air jet pipes 12 are symmetrical about the central axis of the collection box 4. This is beneficial to achieve the effect of blowing and clearing the material drop hole 13 in multiple directions by setting two sets of air jet pipes 12 with their positions symmetrical about the central axis of the collection box 4.

[0036] The spiral roller 16 is positioned on the rotation path of the jet pipe 12, which facilitates the convenient blowing of debris adhering to the surface of the spiral roller 16.

[0037] In this invention, when the CNC machining equipment 1 processes the product, the coolant in the coolant storage box 7 is delivered to the coolant spray pipe 3 through the connecting pump installed outside the liquid delivery pipe 8, so that the coolant acts on the product on the surface of the processing table 2. During product processing, the debris falls into the collection box 4 through the drop hole 13. At the same time, the drive of the first motor 14 drives the rotation of the rotating shaft 15 to drive the spiral roller 16 to rotate, accelerating the adsorption of debris. The air supply pump 10 is turned on, and with the connection of the air supply pipe 11, the gas is sprayed out from the jet pipe 12 to blow and clear the debris adsorbed on the inner wall of the drop hole 13, accelerating the falling efficiency of the debris. The second motor 17 is turned on, and through the rotation of the threaded rod 18, the threaded sliding tooth plate 19 slides along the inner wall of the fixed groove 20. With the rotation of the connecting gear 9, the jet angle of the jet pipe 12 is adjusted, and the debris on the surface of the spiral roller 16 is blown and cleaned simultaneously.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
