Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of steel feeding, and particularly relates to a feeding device of a steel processing equipment. BACKGROUND

[0002] In the field of steel processing, with the development of intelligent manufacturing technology, the automatic feeding link has become a key component for improving processing efficiency and reducing labor costs. Before steel enters a lathe, a milling machine or a grinding machine and other processing equipment, it needs to be accurately transported and positioned from a raw material storage area to a processing station through a feeding device. The clamping stability and positioning accuracy directly determine the subsequent processing quality and production safety.

[0003] The existing steel feeding device is usually composed of a feeding transmission system and a feeding mechanical arm. The feeding transmission system usually adopts a roller transmission structure, which is mainly composed of a driving motor and a plurality of transmission rollers and a rack. The surface of the transmission roller is usually coated with a rubber or polyurethane wear-resistant layer for smoothly conveying the steel from the raw material area to the clamping station. The feeding mechanical arm is usually a 4-6 degree-of-freedom articulated mechanical arm, and the end of the arm is equipped with a clamping mechanism. The clamping mechanism is usually a symmetrically arranged clamping plate structure, which is driven by hydraulic or pneumatic power to grasp and transport the steel.

[0004] Although the existing feeding device can realize automatic feeding of steel, it still has some limitations in practical application. The clamping method of the existing device is usually two-point clamping or single-point support and single-point clamping. For long shaft steel, this clamping method is prone to cause deflection and radial vibration due to self-weight during steel feeding, which directly affects the stability of steel feeding. For thin-walled steel, this clamping method will cause clamping force concentration and deformation of the steel, thereby affecting the processing quality and precision of the steel. For special-shaped parts, this clamping method will directly affect the clamping stability of the device, causing the steel to easily deviate or slip during feeding, which poses a safety hazard.

Multiple requirements of long-axis anti-buckling, thin-wall anti-deformation and special-shaped part anti-deviation during the steel material feeding process are considered, and the stability and adaptability of the feeding device are improved.

[0030] In a preferred embodiment, the working pressure of the inert gas can be set according to actual application, and a gas similar to nitrogen is preferably used, which can reduce the influence of external factors on itself, thereby ensuring the linkage performance of the linkage mechanism 700.

[0031] As shown in Figures 3 to 6 As a preferred embodiment of the present application, the main clamping mechanism 500 includes a hydraulic system 510, a moving block 520, a clamping plate 530 and a side support 540, the hydraulic system 510 is fixed symmetrically on the top of the connecting plate 400, the output end of the hydraulic system 510 is connected with the moving block 520 which is slidingly installed on the transverse guide groove 410, the bottom of the moving block 520 is fixed with the clamping plate 530, the clamping plate 530 is located at the bottom of the connecting plate 400, the front and rear ends of the clamping plate 530 are symmetrically fixed with the side supports 540 connected with the deflection assembly 810, the non-clamping end surface of the clamping plate 530 is vertically and equidistantly provided with installation grooves 550, the installation grooves 550 are transversely and equidistantly provided with sliding holes 560 penetrating the clamping end surface of the clamping plate 530, the installation grooves 550 and the sliding holes 560 are used for installing the adaptive clamping mechanism 600, and the non-clamping end surface of the clamping plate 530 is fixed with the linkage mechanism 700.

[0032] The hydraulic system 510 can drive the two moving blocks 520 to move away from or close to each other in an extendable manner, and the two moving blocks 520 drive the respective clamping plates 530 to move away from or close to each other; in the initial state, the two clamping plates 530 move away from each other, and at this time, the stabilizing assembly 820 on the lateral stabilizing mechanism 800 is located outside the clamping plate 530, so as not to interfere with the clamping of the steel material by the clamping plate 530; When the two clamping plates 530 move close to each other, the two clamping plates 530 can drive the respective adaptive clamping mechanisms 600 to move close to each other, and the adaptive clamping mechanism 600 can not only complete the adaptive clamping of the steel material according to the outer contour of the steel material and improve the clamping stability of the device, but also change the gas flow direction of the inert gas in the adaptive clamping mechanism 600, so as to drive the linkage mechanism 700, so that the linkage mechanism 700 can drive the lateral stabilizing mechanism 800 to clamp the front and rear ends of the steel material, thereby completing the three-point clamping of the steel material in the axial direction of the steel material. According to the geometric stability principle of three points determining a plane, a rigid constraint is formed in the axial direction of the steel material, the overturning moment of single-point or double-point clamping is completely eliminated, the multiple requirements of long-axis anti-buckling, thin-wall anti-deformation, and special-shaped part anti-deviation during the steel material feeding process are considered, and the stability and adaptability of the feeding device are improved.

[0033] In a preferred embodiment, the hydraulic system 510 preferably adopts a hydraulic telescopic structure composed of a hydraulic telescopic cylinder and a hydraulic telescopic rod 812.

[0034] As shown in Figures 3 to 8 As a preferred embodiment of the present application, the adaptive clamping mechanism 600 includes a mounting seat 610, a fixed plate 620, an exhaust head 630, a sliding seat 640, and a clamping rod 650. One end of the mounting seat 610 is fixed with the fixed plate 620, the fixed plate 620 is installed in the mounting groove 550, the mounting seat 610 is hollow inside, and the sliding seat 640 is horizontally and slidably installed on the inner wall of the mounting seat 610. The clamping rod 650 is distributed laterally and equidistantly on one side of the sliding seat 640, one end of the clamping rod 650 penetrates the sliding hole 560 and extends to the inside of the clamping end surface of the clamping plate 530, the sliding seat 640, the fixed plate 620, and the inner wall of the mounting seat 610 form a closed space filled with inert gas, and the fixed plate 620 is fixed with the exhaust head 630 connected with the linkage mechanism 700 and the closed space.

[0035] In the initial state, the inert gas in the linkage mechanism 700 is injected into the mounting seat 610 under the elastic force of the linkage mechanism 700 itself, so that the end face of the slide seat 640 on which the clamping rod 650 is installed is in close contact with the inner wall of the mounting seat 610, and at this time, the volume of the closed space of the mounting seat 610 is in the maximum state; during the process of the clamping rod 650 moving synchronously with the clamping plate 530 and clamping the steel according to the outer contour of the steel, the clamping rod 650 can push the slide seat 640 to move reversely in the mounting seat 610, and during the reverse movement of the slide seat 640 in the mounting seat 610, the volume of the closed space is gradually reduced, so that the slide seat 640 can inject the excess inert gas in the closed space into the linkage mechanism 700, thereby completing the driving of the linkage mechanism 700, so that the lateral stabilizing mechanism 800 can cooperate with the clamping rod 650 to complete the three-point clamping of the steel in the axial direction of the steel, form a rigid constraint in the axial direction of the steel, completely eliminate the overturning moment of single-point or double-point clamping, and improve the stability and adaptability of the feeding device.

[0036] In a preferred embodiment, a sealing material, such as an annular sealing rubber ring, is installed between the outer wall of the slide seat 640 and the inner wall of the mounting seat 610 in the circumferential direction, so as to improve the sealing performance of the closed space.

[0037] As shown in Figures 3 to 9 As a preferred embodiment of the present application, the linkage mechanism 700 includes a piston cylinder 710, a fixing frame 720, an air inlet head 730, a connecting pipe 740, a piston block 750, a piston column 760, and a control block 770, the piston cylinder 710 is fixed on the non-clamping end face of the clamping plate 530 through the fixing frame 720, the side wall of the piston cylinder 710 is distributed with the air inlet head 730, one end of the air inlet head 730 is connected with the air outlet head 630 through the connecting pipe 740, the piston block 750 is slidingly installed in the piston cylinder 710, the piston block 750 divides the space inside the piston cylinder 710 into a driving space and a moving space, the driving space is connected with the other end of the air inlet head 730, the driving space is connected with the closed space in the self-adaptive clamping mechanism 600 and is filled with inert gas, the moving space is respectively installed with a linkage spring and the piston column 760, the two ends of the linkage spring are respectively connected with the piston block 750 and the inner wall of the piston cylinder 710, one end of the piston column 760 is fixed on the piston block 750, the other end of the piston column 760 extends to the outside of the piston cylinder 710 and is connected with the control block 770, and the control block 770 is slidingly connected with the two deflection assemblies 810 arranged on the same side.

[0038] The end faces of the control block 770 on both sides are provided with inclined end portions 780, and the two inclined end portions 780 are respectively in sliding fit with the two deflection assemblies 810 arranged on the same side. The design of the inclined end portions 780 can not only ensure that the deflection assemblies 810 are driven more efficiently, but also reduce the friction between the two, and reduce the loss of force transmission.

[0039] In the initial state, the linkage spring of the moving space can drive the piston block 750 to move into the driving space by the elastic force of the linkage spring, so as to extrude the inert gas in the driving space into the closed space of the mounting seat 610 through the air inlet head 730 and the connecting pipe 740. At this time, the volume of the driving space is in the minimum state, and the volume of the closed space is in the maximum state. During the process of self-adaptive clamping of the clamping rod 650 to the steel, the volume of the closed space is continuously reduced, so that the excess inert gas in the closed space is re-injected into the driving space through the air outlet head 630, the connecting pipe 740 and the air inlet head 730, and the gas pressure in the driving space is continuously increased and gradually greater than the elastic force of the linkage spring. When the force generated by the gas pressure in the driving space is greater than the elastic force of the linkage spring, the piston block 750 can be driven to move in the direction of the moving space, and the volume of the moving space is continuously reduced. The piston block 750 drives the piston column 760 and the control block 770 thereon to move synchronously. The control block 770 can drive the two deflection assemblies 810 on the same side to move away from each other by moving, so that the stable assemblies 820 at the ends of the two deflection assemblies 810 are deflected towards the steel, and the front and rear ends of the steel are clamped. In cooperation with the clamping rod 650, three-point clamping of the steel can be achieved in the axial direction of the steel, so as to form a rigid constraint in the axial direction of the steel, completely eliminate the overturning moment of single-point or double-point clamping, and improve the stability and adaptability of the feeding device.

[0040] In a preferred embodiment, a sealing material, such as an O-shaped sealing rubber ring, is installed between the outer wall of the piston block 750 and the inner wall of the piston cylinder 710, so as to improve the sealing performance of the driving space and avoid leakage of inert gas. A one-way valve in communication with the driving space is further fixed on the side wall of the piston cylinder 710. The one-way valve is provided with a gas pressure sensor. The one-way valve can be used by the worker to fill inert gas into the driving space and the closed space, so that the adaptive clamping mechanism 600 can change the volume of the closed space to inject inert gas into the driving space during clamping of the steel, thereby driving the piston block 750.

[0041] As Figures 3 to 10As shown, in a preferred embodiment of the present invention, the deflection assembly 810 includes a deflection rod 811, a telescopic rod 812, and a connecting rod 813. The deflection rod 811 preferably adopts a V-shaped rod structure. One end of the deflection rod 811 is slidably engaged with the inclined end 780 on the control block 770, and a stabilizing spring 830 is installed between two deflection rods 811 on the same side. The middle part of the deflection rod 811 is rotatably mounted on the side bracket 540. The other end of the deflection rod 811 is slidably mounted with the telescopic rod 812. The end of the telescopic rod 812 is fixed with the connecting rod 813, and a stabilizing assembly 820 is installed on the connecting rod 813.

[0042] The stabilizing component 820 includes a mounting frame 821, a mounting plate 822, elastic sliding columns 823, and a stabilizing plate 824. The mounting frame 821 is rotatably mounted on the connecting rod 813. The mounting plate 822 is vertically fixed on the mounting frame 821. Elastic sliding columns 823 are slidably distributed on the mounting plate 822. The end of the elastic sliding column 823 is fixed to the stabilizing plate 824. The clamping end face on the stabilizing plate 824 faces the same direction as the clamping end face on the clamping plate 530 on the same side.

[0043] Initially, the control block 770 is close to the piston cylinder 710 and in its initial position. The stabilizing spring 830, through its own elastic force, can drive the two deflecting rods 811 located on the same side to move closer to each other and always slide in cooperation with the two inclined ends 780 on the control block 770. When the control block 770 moves away from the piston cylinder 710, its inclined ends 780 can push the two deflecting rods 811 located on the same side away from each other, so that the stabilizing spring 830 is in a stretched and stored state. The two deflecting rods 811, by moving away from each other, can drive the telescopic rod 812 and the connecting rod 813 to deflect closer to the steel. The connecting rod 813 can drive the mounting bracket 821 and the mounting plate 822 to deflect closer to the steel. The elastic sliding column 823 and the stabilizing plate 824 are deflected towards the steel, so that the four clamping plates 530 located at the left and right ends and the front and rear sides of the clamping plate 530 can clamp the front and rear ends of the steel along the clamping position of the adaptive clamping mechanism 600. In addition, by cooperating with the adaptive clamping mechanism 600, the steel is clamped and fixed at three points in the axial direction, forming a rigid constraint in the axial direction of the steel, completely eliminating the overturning moment of single or double point clamping. At the same time, the adaptive structure of the adaptive clamping mechanism 600 is compatible with steel of multiple specifications, and finally achieves the goal of clamping and positioning.
