DETAILED DESCRIPTION

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] As shown in Figures 1 to 5 The utility model provides a kind of automatic feeding mechanism of ceiling type numerical control machine tool, including crossbeam 1, the surface of crossbeam 1 is movably connected with sliding block 2, the lower part of sliding block 2 is provided with clamping structure, the inside of sliding block 2 is fixedly connected with first connecting beam 28, the left and right side surfaces of crossbeam 1 are all fixedly connected with support 3, the inside of support 3 is fixedly connected with second connecting beam 36, the inside of crossbeam 1 is provided with chute 4, the upper surface of sliding block 2 is fixedly connected with abutment block 5, the upper surface of support 3 is fixedly connected with oil storage tank 6, the left surface of oil storage tank 6 is fixedly connected with spring 7, the left end of spring 7 is fixedly connected with driving plate 8, the right side surface of driving plate 8 is fixedly connected with slide column 9, slide column 9 is movably connected in the inside of oil storage tank 6, the right end of slide column 9 is fixedly connected with baffle 10, the left side surface of crossbeam 1 is provided with oil outlet structure.

[0023] When numerical control punch controls feeding mechanism to feed, staff starts first motor 23, because the rotation of the output shaft of first motor 23 drives screw rod 24 to rotate, so that the left and right movement of internally threaded block 25 screw connected with screw rod 24, so that sliding block 2 is located in the inside of chute 4 and moves left and right, can be controlled by the output shaft of first motor 23 additional rotation two circles, so that abutment block 5 and driving plate 8 abut, so that baffle 10 is separated from the oil outlet hole of oil outlet pipe 19, so that the oil in the inside of oil storage tank 6 passes through oil outlet structure, enters the inside of chute 4, so as to reduce the friction between sliding block 2 and crossbeam 1, when abutment block 5 is separated from driving plate 8, because of the elastic potential energy of slide column 9, baffle 10 seals the lubricating oil in the inside of oil storage tank 6.

[0024] Among them, the inside of oil storage tank 6 is movably connected with suspension plate 11, the upper surface of suspension plate 11 is fixedly connected with conduction assembly 12, conduction assembly 12 is movably connected in the upper wall of oil storage tank 6, the front surface of oil storage tank 6 is fixedly connected with C-shaped plate 13, the upper surface of C-shaped plate 13 is fixedly connected with alarm 14, the inside of suspension plate 11 is fixedly connected with oil inlet pipe 15, oil inlet pipe 15 penetrates the upper part of oil storage tank 6, the lower part of oil inlet pipe 15 is fixedly connected with oil pump 16, oil pump 16 is fixedly connected with the right surface of support 3.

[0025] The staff needs to add lubricating oil into the inside of the oil tank 6, and the outside lubricating oil is pumped into the lower part of the floating plate 11 inside the oil tank 6 through the oil pump 16. At this time, the floating plate 11 is subjected to upward thrust, and because the floating plate 11 and the transmission assembly 12 are very light in weight, the transmission assembly 12 slowly rises. When the lubricating oil inside the oil tank 6 is discharged from the oil outlet pipe 19 into the chute 4, the floating plate 11 slowly descends due to its own gravity. When the upper surface of the upper part of the transmission assembly 12 touches the upper part of the alarm 14, the alarm 14 will give an alarm, thereby reminding the staff to add lubricating oil in time.

[0026] The clamping structure includes a lifting limiting block 27 fixedly connected to the lower surface of the sliding block 2. The inside of the lifting limiting block 27 movably connects a sliding plate 17, and the lower part of the sliding plate 17 is fixedly connected with a mechanical hand 18.

[0027] The lifting limiting block 27 provides a lifting space for the sliding plate 17, and the mechanical hand 18 clamps and transports the material.

[0028] The oil outlet structure includes an oil outlet pipe 19 fixedly connected to the lower left surface of the oil tank 6. The right upper surface of the cross beam 1 is fixedly connected with a guide plate 20, and the left surface of the support 3 is fixedly connected with a protection block 21.

[0029] The oil outlet pipe 19 sends the lubricating oil inside the oil tank 6 into the inside of the chute 4, and the upper surface of the guide plate 20 has a certain inclination angle, so that the lubricating oil flowing out from the lower part of the oil outlet pipe 19 can better enter the gap between the sliding block 2 and the cross beam 1. The design of the protection block 21 prevents the sliding block 2 from impacting the oil outlet pipe 19 and causing the oil outlet pipe 19 to break.

[0030] The driving structure includes a first supporting plate 22 fixedly connected to the rear surface of the support 3. The upper surface of the first supporting plate 22 is fixedly installed with a first motor 23. The output shaft of the first motor 23 is fixedly connected with a threaded rod 24. The rear surface of the sliding block 2 is fixedly connected with an internal threaded block 25. The threaded rod 24 is internally threadedly connected with the internal threaded block 25. The right surface of the support 3 is fixedly connected with a limiting block 26.

[0031] The first supporting plate 22 provides a support point for the first motor 23. The rotation of the output shaft of the first motor 23 drives the internal threaded block 25 threadedly connected to the surface of the threaded rod 24 to move left and right, thereby transporting the material. However, the limiting block 26 and the abutting block 5 are on the same horizontal line, preventing the second motor 30 from impacting the support 3.

[0032] The rear lifting limit block 27 has a second support plate 29 fixedly connected to its left side surface, a second motor 30 fixedly installed on the upper surface of the second support plate 29, a rotating shaft 31 rotatably connected to the upper left side surface of the lifting limit block 27, a toothed chain 32 drivingly connected between the rotating shaft 31 and the output shaft of the second motor 30, and a rack 33 fixedly connected to the left side surface of the slide plate 17, with the rack 33 and the toothed chain 32 meshing with each other internally.

[0033] The second support plate 29 provides support to the second motor 30, and the rotation of the output shaft of the second motor 30 drives the rotation of the toothed chain 32. Since the rack 33 and the toothed chain 32 mesh with each other, the slide plate 17 moves up and down inside the lifting limit block 27.

[0034] Among them, the left side surface of the front lifting limit block 27 is fixedly connected to the limit component 34, and the front left side surface of the slide plate 17 is fixedly connected to the fixing block 35, and the fixing block 35 is internally movably connected to the limit component 34.

[0035] The sliding plate 17 can be raised and lowered more stably and reliably by moving the fixed block 35 up and down on the middle surface of the limiting component 34.

[0036] Working principle and usage process of this utility model:

[0037] When the CNC-controlled feeding mechanism is feeding, the operator starts the first motor 23. The rotation of the output shaft of the first motor 23 drives the threaded rod 24 to rotate, which causes the internal threaded block 25, which is threaded to the threaded rod 24, to move left and right. This causes the slider 2 to move left and right inside the slide groove 4. By controlling the output shaft of the first motor 23 to rotate two more times, the abutting block 5 will abut against the drive plate 8, which will cause the baffle 10 to disengage from the oil outlet hole of the oil outlet pipe 19. This allows the oil inside the oil tank 6 to enter the slide groove 4 through the oil outlet structure, thereby reducing the friction between the slider 2 and the crossbeam 1. However, when the abutting block 5 disengages from the drive plate 8, the elastic potential energy of the sliding column 9 causes the baffle 10 to seal the lubricating oil inside the oil tank 6.

[0038] Workers need to add lubricating oil into the oil reservoir 6. The oil pump 16 draws the external lubricating oil into the lower part of the suspension plate 11 inside the oil reservoir 6. At this time, the suspension plate 11 is pushed upward. Since the suspension plate 11 and the transmission component 12 are very light, the transmission component 12 will slowly rise. When the lubricating oil inside the oil reservoir 6 is discharged from the oil outlet pipe 19 into the chute 4, the suspension plate 11 will slowly descend due to its own gravity. When the upper lower surface of the transmission component 12 touches the upper part of the alarm 14, the alarm 14 will sound an alarm, thus reminding the workers to add lubricating oil in time.

[0039] The lifting limiting block 27 provides the lifting space for the sliding plate 17, and the mechanical hand 18 clamps and transports the material.

[0040] The lubricating oil in the oil storage tank 6 is sent into the inside of the sliding groove 4 through the oil outlet pipe 19, and the upper surface of the oil guide plate 20 has a certain inclination angle, so that the lubricating oil flowing out from the lower part of the oil outlet pipe 19 can better enter the gap between the sliding block 2 and the cross beam 1, and the design of the protection block 21 prevents the sliding block 2 from impacting and breaking the oil outlet pipe 19.

[0041] The first motor 23 is provided with a support point by the first supporting plate 22, and the rotation of the output shaft of the first motor 23 drives the left and right movement of the internal threaded block 25 threaded on the surface of the threaded rod 24, so as to transport the material, and the limiting block 26 and the abutting block 5 are in the same horizontal line, preventing the second motor 30 from impacting the support 3.

[0042] The second motor 30 is provided with a support force by the second supporting plate 29, and the rotation of the output shaft of the second motor 30 drives the rotation of the toothed chain 32, and since the rack 33 and the toothed chain 32 are internally meshed with each other, the sliding plate 17 is moved up and down in the inside of the lifting limiting block 27.

[0043] The fixed block 35 is moved up and down on the surface of the limiting assembly 34, so as to make the lifting of the sliding plate 17 more stable and reliable.
