Description

Technical Field

[0001] The utility model relates to a double servo vehicle for automatic cutting of bars, belonging to the technical field of automatic bar cutting. Background Art

[0002] In automatic bar cutting equipment, bars dozens of meters long usually need to be cut into several standard bars, and the cutting is usually carried out by a cutting machine; the bars are usually conveyed by a chain conveyor, and the bars fall onto the driving chain of the chain conveyor, and the friction force is used to drive the bars forward.

[0003] When sending the bars to the cutting machine for cutting, roller paths are generally arranged at the feeding and discharging positions of the cutting machine. However, if only relying on the driving of the rollers on the roller path to send the bars to the cutting machine for cutting, the feeding and discharging dimensions cannot be accurately controlled, and the error is large because slipping may occur between the bars and the rollers on the roller path; if manual auxiliary measurement is used, the efficiency of automatic cutting is reduced.

[0004] Based on this, the present utility model is proposed. Content of the Utility Model

[0029] Embodiment 1

[0030] As Figures 1 to 4 shown, the double-servo vehicle for automatic cutting of bars includes a cutting machine 5 for cutting a long bar into a plurality of standard bars, a feeding servo shaft mechanism 3 for feeding the long bar to the cutting machine 5 for cutting, and a discharging servo shaft mechanism 17 for dragging the cut standard bars away from the cutting machine 5. The feeding servo shaft mechanism 3 includes a bed 31, a jaw platform 33, a third driving mechanism for driving the jaw platform 33 to perform translational reciprocating motion along the length direction of the bed 31, and a jaw mechanism 36 provided below the jaw platform 33.

[0031] The third driving mechanism includes a first rack 32 fixedly installed on the outside of the bed body 31, a first gear 34 externally meshed with the first rack 32, and a first motor 35 for driving the first gear 34 to rotate. The first motor 35 is installed on the jaw platform 33, and a first guide rail 311 is provided between the jaw platform 33 and the bed body 31.

[0032] The jaw mechanism 36 includes two jaw bodies 361 arranged oppositely. A second guide rail 362 is provided between the jaw bodies 361 and the jaw platform 33. The two jaw bodies 361 perform synchronous opening or closing actions through a jaw gear driving mechanism.

[0033] As Figure 7 shown, the jaw gear driving mechanism includes a connecting plate 364 fixedly connected to the jaw body 361, a second rack 365 fixedly connected to the connecting plate 364, and a main gear 366. Both second racks 365 are meshed with the main gear 366, and the main gear 366 is driven by a second motor.

[0034] The working principle of the double-servo vehicle for automatic cutting of bars is as follows: An inlet roller table 4 is provided at the inlet of the cutting machine 5, and an outlet roller table 21 is provided at the outlet of the cutting machine 5. The long bar on the inlet roller table 4 is driven by the inlet servo shaft mechanism 3 to move horizontally in the direction of the cutting machine 5. The cutting machine 5 cuts the long bar into several standard bars, and the cut standard bars are driven onto the outlet roller table 21 by the outlet servo shaft mechanism 17.

[0035] In the present utility model, through the double-servo shaft mechanism (inlet servo shaft mechanism 3, outlet servo shaft mechanism 17), different inlet, outlet, and cutting processes can be designed according to actual needs to meet the diverse production requirements.

[0036] The structure of the outlet servo shaft mechanism 17 is the same as that of the inlet servo shaft mechanism 3. Taking the working principle of the inlet servo shaft mechanism 3 as an example:

[0037] The first motor 35 drives the first gear 34 to rotate. By using the first rack 32, the jaw platform 33 can move horizontally along the direction of the first rack 32. By precisely setting parameters such as the number of teeth on the first rack 32, the advancing dimension of the jaw platform 33 can be precisely controlled to meet the dimensional requirements for cutting. In addition, through the jaw gear driving mechanism, the two jaw bodies 361 are driven to perform synchronous opening or closing actions, enabling the jaw mechanism 36 to clamp the long bar or the standard bar.

[0038] The principle of the jaw gear driving mechanism is as follows:

[0039] By using only one main gear 366, the two second racks 365 can be synchronously moved, thereby driving the two jaw bodies 361 to open or close synchronously.

[0040] Embodiment 2

[0041] To ensure accuracy, the first rack 32 must be kept lubricated and lubricating oil needs to be applied regularly; as Figures 3 to 6 shown, an oiling gear 37 is also externally meshed with the outside of the first rack 32. A connecting plate 38 is installed between the jaw platform 33 and the oiling gear 37. The oiling gear 37 includes a gear body 371. The axle of the gear body 371 is rotatably connected to the connecting plate 38. Helical teeth 372 and tooth grooves 373 are provided on the outer periphery of the gear body 371. A lubricating oil channel 375 is provided in the center of the gear body 371. A plurality of oil outlet holes 374 are arranged radially along the gear body 371 between the lubricating oil channel 375 and the tooth grooves 373; a lubricating oil pumping device communicated with the lubricating oil channel 375 is installed on the jaw platform 33.

[0042] The lubricating oil pumping device includes an oil storage barrel storing lubricating oil and an oil pump.

[0043] The lubricating oil in the oil storage barrel is regularly and quantitatively input into the lubricating oil channel 375 through the oil pump, and then oil is injected into the tooth grooves 373 through the oil outlet holes 374. During the translational movement of the oiling gear 37 along with the jaw platform 33, the lubricating oil in the tooth grooves 373 can lubricate the first rack 32.

[0044] Embodiment 3

[0045] To ensure that the jaw mechanism 36 has sufficient frictional force on long bars or standard bars, a backing plate 363 is fixedly installed on the inner side of the jaw body 361, and concave and convex patterns are provided on the inner side surface of the backing plate 363.

[0046] In addition, to meet the requirements of limiting and shock absorption, a shock absorption and limiting block 39 is fixedly installed at the end of the bed body 31.

[0047] Embodiment 4

[0048] In this embodiment, compared with straight teeth, helical teeth 372 are adopted and the helix angle of the helical teeth 372 is controlled to be 12°. The oil outlet pressure of the oil pump changes in a pulsed manner. These measures are all to ensure that there is sufficient lubricating oil on the first rack 32 in a short time. At the same time, it also avoids excessive lubricating oil dripping downward on the first rack 32, resulting in waste and pollution.

[0049] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
