Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment, specifically a one-time forming multi-axis CNC machining center. Background Technology

[0002] A one-piece multi-axis CNC machining center consists of a bed, column, spindle, worktable, tool magazine, cooling and lubrication system, etc., and is a CNC machine tool that achieves machining through CNC axis drive and control. It is mainly used for high-efficiency machining in the automotive, aerospace, and hydraulic industries. This equipment has various structural forms such as vertical, horizontal, and gantry types, and supports synchronous machining and alternating machining modes.

[0003] In CNC machining, the cutting fluid spray system plays a crucial role in cooling, lubricating, and removing chips from the cutting tools and workpieces. However, the nozzles of traditional spray systems are prone to clogging due to cutting fluid residue and metal debris accumulation, leading to reduced spraying effectiveness and affecting machining accuracy and tool life. Current technologies typically involve manual cleaning or nozzle replacement during machine shutdown, which is not only inefficient but also increases labor costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a one-time forming multi-axis CNC machining center, the structure of which includes a frame, a work platform mounted on the frame for placing and fixing workpieces, and a spray head mounted on the work platform for spraying workpieces. The spray head is adjustablely mounted on the work platform via a bracket. The nozzle includes a housing on a mounting bracket, a spiral scraper disposed inside the housing for cleaning the nozzle outlet, and a drive mechanism installed inside the housing to drive the spiral scraper to reciprocate. The housing is provided with a sealing baffle plate inside, which divides the housing into a front chamber and a rear chamber; The driving mechanism includes an electromagnet disposed in the rear cavity. The electromagnet is isolated in the rear cavity of the housing by a baffle. An armature that is magnetically coupled to the electromagnet is provided on the front side of the baffle. A support rod is connected to the end of the armature away from the baffle. The end of the support rod away from the baffle is connected to both ends of the spiral scraper. The armature is wrapped in a movable sleeve that is slidably connected to the inner wall of the housing. The movable sleeve is a cylindrical structure with a closed end and an open end. The closed end faces the spiral scraper and is connected to the support rod. The open end faces the baffle. A compression spring is coaxially disposed inside the movable sleeve. Its two ends abut against the inner wall of the closed end of the movable sleeve and the baffle, respectively. When the electromagnet is energized, the armature drives the spiral scraper to move towards the baffle; when the power is off, the spring pushes the spiral scraper to move towards the outlet of the housing for cleaning.

[0005] Furthermore, the front end of the housing is provided with a conical outlet, and the lower part of the housing behind the conical outlet is provided with a water inlet, which is connected to the coolant supply system through a pipeline.

[0006] Furthermore, the outer diameter of the spiral scraper is the same as the minimum inner diameter of the conical outlet, so as to achieve full contact cleaning of the inner wall of the conical outlet.

[0007] Furthermore, a groove is provided inside the housing at the front end of the baffle, and a ball bearing that is slidably connected to the groove is embedded in the movable sleeve.

[0008] Furthermore, the inclination angle of the arc-shaped inclined groove is 15-30 degrees.

[0009] Furthermore, the support rod is located at the central axis of the housing and runs in the same direction as the central axis.

[0010] Furthermore, the spring is made of 316L stainless steel.

[0011] Furthermore, the armature is made of 430 stainless steel.

[0012] Compared with the prior art, the present invention has the following beneficial effects: During its reciprocating motion, the spiral scraper not only effectively removes residues adhering to the inner wall of the nozzle, but also, combined with high-pressure coolant spray, achieves a dual function of flushing and mechanical cleaning. This significantly improves the nozzle's anti-clogging performance, ensures the continuous and stable operation of the spray system, and allows for cleaning without disassembly, thus increasing equipment utilization.

[0013] When the spiral scraper performs reciprocating cleaning motion, the cooperation between the groove and the ball can drive the spiral scraper to rotate at an angle in linear motion, effectively reducing motion resistance. This allows the spiral scraper to more thoroughly remove deposits from the nozzle cavity, avoid cleaning dead corners, and further improve cleaning efficiency and nozzle lifespan.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0020] Examples, such as Figures 1-4 As shown: This utility model provides a one-time forming multi-axis CNC machining center, the structure of which includes a frame 1, a work platform 2 set on the frame 1 for placing and fixing workpieces, and a spray head 3 set on the work platform 2 for spraying workpieces. The spray head 3 is adjustablely mounted on the work platform 2 by a bracket 4. Specifically, the nozzle 3 includes a housing 30 on the mounting bracket 4, a spiral scraper 31 disposed in the housing 30 for cleaning the nozzle outlet, and a drive mechanism 32 installed in the housing 30 and driving the spiral scraper 31 to reciprocate. The housing 30 is provided with a sealing baffle 300 inside, which divides the housing 30 into a front chamber and a rear chamber to ensure that water does not enter the rear chamber; To drive the reciprocating motion of the spiral scraper 31, an electromagnetic drive is used for the drive mechanism 32. Specifically, the drive mechanism 32 includes an electromagnet 320 disposed in the rear chamber. The electromagnet 320 is isolated in the rear chamber of the housing 30 by a baffle 300 to ensure that the electromagnet 320 does not come into contact with water. An armature 321 magnetically coupled to the electromagnet 320 is provided on the front side of the baffle 300, facilitating the driving of the armature 321. A support rod 322 is connected to the end of the armature 321 away from the baffle 300. The end of the support rod 322 away from the baffle 300 is connected to the spiral scraper. The two ends of 31 are connected, so that the movement of armature 321 can directly drive the spiral scraper 31 to move. The armature 321 is wrapped in a movable sleeve 323 that is slidably connected to the inner wall of the housing 30. The movable sleeve 323 is a cylindrical structure with a closed end and an open end. The closed end faces the spiral scraper 31 and is connected to the support rod 322. The open end faces the baffle 300. A compression spring 324 is coaxially arranged inside the movable sleeve 323. Its two ends abut against the inner wall of the closed end of the movable sleeve 323 and the baffle 300, respectively. The movable sleeve 323 can ensure that the armature 321 can move linearly. Therefore, when the electromagnet 320 is energized, the armature 321 drives the spiral scraper 31 to move towards the baffle; when the power is off, the spring 324 pushes the spiral scraper 31 to move towards the outlet of the housing 30 for cleaning. The cleaning is performed by de-energizing and resets inward when the power is on. The spiral scraper 31 is designed to clean simultaneously during spraying without affecting the water output.

[0021] It should be noted that the front end of the housing 30 is provided with a conical outlet 301, and the bottom of the housing 30 behind the conical outlet 301 is provided with a water inlet 302. The water inlet 302 is connected to the coolant supply system through a pipeline to ensure that the nozzle 3 can smoothly enter and exit water.

[0022] In order to enable the spiral scraper 31 to conform to the inner wall of the conical outlet 301 for cleaning, the outer diameter of the spiral scraper 31 is designed to be the same as the minimum inner diameter of the conical outlet 301, so as to achieve full contact cleaning of the inner wall of the conical outlet 301 and ensure thorough cleaning.

[0023] To make the spiral scraper 31 work more smoothly during cleaning, a groove 303 is provided inside the housing 30 at the front end of the baffle 300. A ball bearing 325 is embedded in the movable sleeve 323 and is slidably connected to the groove 303. The inclination angle of the arc-shaped inclined groove 303 is 15-30 degrees, which allows the spiral scraper 31 to rotate forward and reduce resistance.

[0024] In order to keep the spiral scraper 31 in contact with the conical outlet 301, the support rod 322 that fixes the spiral scraper 31 is located at the central axis of the housing 30 and is aligned with the central axis.

[0025] To prevent the parts from rusting due to contact with water, the spring is made of 316L stainless steel and the armature is made of 430 stainless steel.

[0026] In practical implementation, when the electromagnet 320 is energized, the armature 321 is attracted by the magnetic force, and the armature 321 drives the spiral scraper 31 to move towards the baffle. The spiral scraper 31 is in a retracted state and does not work. When working, the electromagnet 320 is de-energized, and under the elastic force of the compression spring 324, the spiral scraper 31 is pushed forward. At the same time, the ball bearings 325 on the movable sleeve 323 slide along the slide groove 303, and the movable sleeve 323 rotates. Therefore, the spiral scraper 31 can rotate and move forward to clean the inner wall of the conical outlet 301. Combined with the high-pressure coolant spray, flushing and mechanical cleaning are achieved.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
