Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and more specifically, it relates to a slide table for a deep hole drilling machine. Background Technology

[0002] The slide table for deep hole drilling machines is a core functional module in deep hole machining equipment that enables precise linear motion of the tool or workpiece. It is mainly used to control the displacement accuracy, motion stability and dynamic response capability of the feed system during drilling. Structurally, the slide table usually consists of five parts: basic frame, drive system, guide mechanism, position detection unit and auxiliary devices.

[0003] Traditional slides are mostly fixedly connected to deep hole drilling machines, and the position of the slide is not adjustable. Since the angle of deep hole drilling is mostly not adjustable, deep hole machining is very inconvenient when it is necessary to machine inclined holes or drill holes at different positions on the workpiece. If there is no lubrication device between the sliding track and the slider on the slide, the frictional resistance increases significantly, resulting in abnormal wear on the contact surface of the moving parts.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a slide table for a deep hole drilling machine, which has the following beneficial effects:

[0017] 1. The handwheel drives the worm gear and worm wheel to rotate, which facilitates the rotation of the rotating shaft and support table, thereby adjusting the rotation angle of the slide body and improving the convenience of adjusting the slide angle of the deep hole drilling rig. The drive motor drives the drive screw to rotate, which facilitates the movement of the slider on the support table.

[0018] 2. The oil injection plate is squeezed by the oil injection airbag, and the position of the oil injection plate is adjusted.

[0029] Please see Figures 1-5A slide table for a deep hole drilling machine includes a slide table body 1, a support base 2, a rotating shaft 3 and a support platform 4 on the support base 2, a worm gear 5 and a handwheel 6 rotatably mounted on the support base 2, a worm wheel 7 mounted on the rotating shaft 3, symmetrical sliding rails 8 on the support platform 4, sliders 9 on the sliding rails 8, a plurality of lubrication grooves 10 symmetrically arrayed on the sliding rails 8, an oil injection plate 11 slidingly mounted in each lubrication groove 10, an oil injection airbag 12 at the bottom of the oil injection plate 11, an oil outlet hole 13 at the top of the lubrication groove 10, oil outlet channels 14 connected to both sides of the oil outlet hole 13, a control channel 15 connected to the center of the oil outlet channel 14, a control spring 16 mounted in the control channel 15, a plug 17 at one end of the control spring 16, an air supply device on the sliding rails 8, a drive motor 28 on the support base 2, a drive screw 29 mounted on the motor shaft of the drive motor 28, and the drive screw 29 threadedly connected to the slider 9.

[0030] In this embodiment, during use, the handwheel 6 is rotated according to the required angle of the slide body 1. The handwheel 6 drives the worm gear 5 to rotate, which in turn drives the rotating shaft 3 and the worm wheel 7 to rotate. The rotating shaft 3 drives the support platform 4 and the slider 9 to move. The drive motor 28 is started, and the drive motor 28 drives the drive screw 29 to rotate. Through the threaded engagement between the drive screw 29 and the slider 9, the slider 9 is driven to move on the sliding track 8.

[0031] Please see Figures 4-5 As one embodiment of the air replenishment device: the air replenishment device includes an air replenishment groove 18, which is disposed between two lubrication grooves 10 on a sliding rail 8. An air replenishment plate 19 is slidably disposed on the air replenishment groove 18. A first one-way valve 20 is disposed between the air replenishment groove 18 and the oil injection airbag 12. A second one-way valve 21 is disposed at the bottom of the air replenishment groove 18. A filter screen 22 is sleeved on the outside of the second one-way valve 21. An air replenishment rod 23 is slidably disposed on the sliding rail 8. One end of the air replenishment rod 23 is fixedly connected to the air replenishment plate 19, and the other end is provided with an air replenishment spring 24 on the sliding rail 8. An air replenishment spring 25 is disposed between the air replenishment plate 19 and the air replenishment groove 18. An oil injection valve 26 is disposed at one end of the lubrication groove 10, and an exhaust valve 27 is disposed at one end of the oil injection airbag 12.

[0032] More specifically, lubricating oil is injected into the lubrication groove 10 through the oil injection valve 26. When the slider 9 moves on the sliding track 8, the slider 9 compresses the air replenishing spring 25 on the sliding track 8. The air replenishing spring 24 presses down on the air replenishing rod 23 and the air replenishing plate 19. The air replenishing rod 23 replenishes the gas in the air replenishing groove 18 into the oil injection airbag 12 through the first one-way valve 20. After the slider 9 passes the position of the air replenishing spring 24, the air replenishing plate 19 moves upward under the elastic force of the air replenishing spring 25 and the air replenishing spring 24. In position, through the action of the second one-way valve 21 and the filter screen 22, dust-free gas is added to the air replenishment tank 18. After the gas enters the oil injection air bag 12, the oil injection air bag 12 expands and squeezes the oil injection plate 11 upward. The oil injection plate 11 moves upward and squeezes the lubricating oil in the lubrication tank 10. The lubricating oil squeezes the plug 17 and is discharged through the oil outlet 14, lubricating the slider 9 and the sliding track 8, reducing wear. By setting the control spring 16 and the plug 17, the lubricating oil is prevented from flowing back and contaminating the lubricating oil in the lubrication tank 10.

[0033] In summary, when the entire device is in use or running: during use, to adjust the angle of the slide body 1 as needed, turn the handwheel 6. The handwheel 6 drives the worm gear 5 to rotate, which in turn drives the rotating shaft 3 and the worm wheel 7 to rotate. The rotating shaft 3 drives the support platform 4 and the slider 9 to move. Start the drive motor 28. The drive motor 28 drives the drive screw 29 to rotate. Through the threaded engagement between the drive screw 29 and the slider 9, the slider 9 is moved on the sliding track 8.

[0034] Lubricating oil is injected into the lubrication groove 10 through the oil injection valve 26. When the slider 9 moves on the sliding track 8, the slider 9 compresses the air replenishing spring 25 on the sliding track 8. The air replenishing spring 24 presses down on the air replenishing rod 23 and the air replenishing plate 19. The air replenishing rod 23 replenishes the gas in the air replenishing groove 18 into the oil injection airbag 12 through the first one-way valve 20. After the slider 9 passes the position of the air replenishing spring 24, the air replenishing plate 19 moves upward and resets under the elastic force of the air replenishing spring 25 and the air replenishing spring 24. Through the action of the second one-way valve 21 and the filter screen 22, dust-free gas is added to the air replenishment tank 18. After the gas enters the oil injection air bag 12, the oil injection air bag 12 expands and squeezes the oil injection plate 11 upward. The oil injection plate 11 moves upward and squeezes the lubricating oil in the lubrication tank 10. The lubricating oil squeezes the plug 17 and is discharged through the oil outlet 14, which lubricates the slider 9 and the sliding track 8 and reduces wear. By setting the control spring 16 and the plug 17, the lubricating oil is prevented from flowing back and contaminating the lubricating oil in the lubrication tank 10.
