The spindle is equipped with a drill bit or cutting tool, and machining operations are performed by rotating the drill bit or cutting tool. It has a wide range of applications.

[0003] For example, Chinese Patent No. CN117532360A discloses a CNC machining center with multi-directional machining function, including a base, a frame fixed on the base, two protective doors at the front of the frame, observation windows on the protective doors, a machining table installed on the base, a limit component installed on the machining table, a support base fixed inside the limit component, a box on each side of the support base, a positioning component inside the box, and an adjustment component and a drive component respectively on the side of the two boxes that are far apart from each other.

[0004] During workpiece machining, operators typically monitor the machining status through an observation window on a protective door. However, during prolonged machining, waste chips are inevitably generated, and the cutting fluid used in the machining center may splash onto the inside of the observation window, interfering with its clarity. Directly opening the protective door to clean the inside of the observation window poses a safety risk to the operator, and currently, it is not possible to clean the inside of the observation window during workpiece machining. Utility Model Content

A nozzle head is provided at the bottom of the nozzle, and a plurality of spray holes communicating with the nozzle are provided at the bottom of the nozzle head. The nozzle is connected to a water pump through a connecting pipe.

[0007] Furthermore, the driving device includes an upper knob and a lower knob rotatably mounted on the sliding door, a toothed belt sleeved on the upper knob and the lower knob, a sliding door having a groove, a slider slidably connected to the groove on the nozzle, one side of the slider being drivenly connected to the toothed belt, and the upper knob or the lower knob extending through to the surface of the sliding door.

[0008] Furthermore, there are two slides distributed on both sides of the observation window, and two sliders, namely a left slider and a right slider that are slidably connected to the slides, and the right slider is connected to a toothed belt drive.

[0009] Furthermore, a protective cover for nozzle protection is also provided on the back of the sliding door.

[0010] Furthermore, an elastic cleaning cotton strip is provided at the bottom of the nozzle.

[0011] Furthermore, the water spray angle of each nozzle is tilted relative to the observation window.

[0012] Furthermore, the processing device includes a slide seat slidably mounted on the frame and a processing assembly mounted on the slide seat. The processing assembly includes a motor, a spindle driven by the motor via a belt, and a drill bit mounted on the spindle.

[0013] Furthermore, the fixing device includes a clamp that is slidably mounted on the frame and a fixed seat that is fixedly mounted on the frame and spaced apart from the clamp, wherein the workpiece is clamped between the fixed seat and the clamp.

[0014] Furthermore, a positioning plate is provided on one side of the fixed base, and the positioning plate is provided with positioning holes for workpiece insertion. A support base for supporting the positioning plate is also provided on the frame.

[0015] Furthermore, a waste collection box is also provided at the bottom of the frame.

[0016] The technical solution provided by this utility model has at least the following technical effects:

[0017] The single-head deep hole machining tool disclosed in this application requires the operator to monitor the workpiece through an observation window during the machining process. To avoid obstruction of vision, when the inside of the observation window needs cleaning, the operator can start a water pump via a switch, which in turn activates a drive device. The drive device then moves the nozzle slowly from top to bottom. Driven by the water pump, the nozzle sprays cleaning fluid through nozzles, effectively removing debris and other dirt from the inside of the observation window. This ensures the operator can clearly monitor the workpiece through the observation window, making the operation convenient, practical, and the cleaning method safer. Attached Figure Description

[0027] like Figure 1 , Figure 2 As shown, this embodiment discloses a single-head deep hole machining machine tool, including a machine tool body. The machine tool body includes a frame 1, a machining device mounted on the frame 1, and a fixing device for clamping and fixing the workpiece. The machining device includes a slide 12 slidably mounted on the frame 1 and a machining assembly mounted on the slide 12. The machining assembly includes a motor 13, a spindle 14 driven by the motor 13 via a belt, and a drill bit mounted on the spindle 14. The slide 12 is driven by a hydraulic cylinder or a lead screw. The motor 13 drives the spindle 14 to rotate via a belt, which in turn drives the drill bit to rotate. During the rotation of the drill bit, the hydraulic cylinder or lead screw pushes the slide 12 and the drill bit as a whole to slide and feed.

[0028] The fixing device includes a clamping seat 16 slidably mounted on the frame 1 and a fixed seat 18 fixedly mounted on the frame 1 and spaced apart from the clamping seat 16. The workpiece is clamped between the fixed seat 18 and the clamping seat 16. The clamping seat 16 is also driven by a hydraulic cylinder. A push rod is provided on the clamping seat 16. When the hydraulic cylinder drives the clamping seat 16 to move, the workpiece is clamped and fixed between the push rod and the fixed seat 18. In order to achieve workpiece positioning, a positioning plate 15 is provided on one side of the fixed seat 18. The positioning plate 15 is provided with a positioning hole for the workpiece to be inserted. Positioning realizes the machining positioning of the workpiece. Under the action of the positioning hole, it is convenient for the drill bit to pass through the positioning hole to process the workpiece. In order to further enhance the stability of the positioning plate 15, a support seat 17 for supporting the positioning plate 15 is also provided on the frame 1. At the same time, a V-shaped groove is provided on the support seat 17 to further realize the positioning support of the positioning plate 15 and improve the stability of the workpiece during processing.

[0029] A collection box 19 for collecting waste chips is installed at the bottom of the frame 1. Waste chips generated during workpiece processing will be effectively collected in this box. When it is necessary to clean the waste chips in the collection box 19, they can be easily separated from the frame 1 and pulled out, making the operation simple.

[0030] like Figure 3 , Figure 4 , Figure 5As shown, a sliding door 2 is slidably mounted on the frame 1. A transparent observation window 3 is provided on the sliding door 2. A cleaning device for cleaning the observation window 3 is provided on the back of the sliding door 2. The cleaning device includes a spray pipe 41 slidably mounted on the sliding door 2 and a driving device 4 for driving the spray pipe 41 to move. A nozzle 42 is provided at the bottom of the spray pipe 41. A plurality of spray holes 43 communicating with the spray pipe 41 are provided at the bottom of the nozzle 42. The spray pipe 41 is connected to a water pump through a connecting pipe 44 (the water pump is located inside the machine housing and is controlled by a switch. The water pump is connected to cleaning fluid. The specific connection structure and principle are well known to those skilled in the art and will not be described in detail in this embodiment).

[0031] The driving device 4 includes an upper knob 5 and a lower knob 6 rotatably mounted on the sliding door 2, and a toothed belt 7 sleeved on the upper knob 5 and the lower knob 6. The sliding door 2 is provided with a sliding groove 8, and the nozzle 41 is provided with a slider slidably connected to the sliding groove 8. One side of the slider is driven by the toothed belt 7. To improve the stability of the nozzle 42's movement, two sliding grooves 8 are provided, distributed on both sides of the observation window 3. Two sliders are provided, a left slider and a right slider 9 slidably connected to the sliding groove 8. The right slider 9 is driven by the toothed belt 7. The upper knob 5 or the lower knob 6 extends through to the surface of the sliding door 2. In this embodiment, the upper knob 5 extends through to the surface of the sliding door 2. The operator can rotate the upper knob 5 from the outside of the sliding door 2, causing the upper knob 5 to drive the transmission belt to rotate. Since the toothed belt 7 is engaged with the right slider 9, it will drive the nozzle 41 to move via the slider. Specifically, during workpiece processing, the operator needs to monitor the workpiece through the observation window 3. To avoid obstructed vision, when the inside of the observation window 3 needs cleaning, the operator can start the water pump via a switch and rotate the upper knob 5. The upper knob 5 then drives the nozzle 41 to move slowly from top to bottom. Driven by the water pump, the nozzle 41 sprays cleaning fluid through the nozzle 43, effectively removing debris and other dirt from the inside of the observation window 3, ensuring that the operator can clearly monitor through the observation window 3. It is easy to operate and highly practical. After cleaning is completed, rotate the upper knob 5 in the opposite direction to reset the nozzle 41.

[0032] In this embodiment, the water spray angle of each nozzle 43 is tilted relative to the observation window 3 to enhance the cleaning efficiency of the nozzle 41. To further improve the cleaning effect of the observation window 3, an elastic cleaning swab 11 is specially provided at the bottom of the nozzle 41. After the nozzle 41 finishes spraying, the elastic cleaning swab 11 can perform additional wiping on the observation window 3, thereby achieving a better cleaning effect. To ensure that the elastic cleaning swab 11 can smoothly return to its original position with the nozzle 41, the top edge of the observation window 3 is designed with a beveled structure. A protective device for the nozzle 41, namely a protective cover, is also provided on the back of the sliding door 2 to ensure that the nozzle 41 is properly protected when not in operation.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
