[0012] Furthermore, the return spring is a conical spring.

[0013] Furthermore, the guide seat satisfies the following formula:

[0014] Fsinα-μFcosα>0

[0015] Among them, F is the thrust exerted on the outer cylinder; μ is the static friction coefficient; α is the inclination angle of the inner surface at the small end of the oil filling hole.

[0016] Furthermore, the elastic coefficient k of the elastic body satisfies the following formula:

DETAILED DESCRIPTION

[0033] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Example 1

[0036] This embodiment describes a sintering trolley wheel oiling device. Figures 1 to 4 As shown, it includes a horizontally arranged mobile platform 17, a slideway 14 is installed at the bottom of the mobile platform 17 to enable it to move forward and backward, and also includes a guide seat 1 for being installed on the sintering table wheel, and an oil filling hole 19 is opened on the guide seat 1 to add oil to the sintering table wheel.

[0037] The oil filling hole 19 has a cone structure as a whole, and a circular cone structure is preferably selected. The specific structure depends on the structure of the oiling gun nozzle 2. The small end is used to refuel the sintering trolley wheel, and a refueling assembly is installed on the mobile platform 17 corresponding to the large end. The guide seat 1 is located on the right side of the refueling assembly.

[0038] The refueling assembly includes an outer cylinder 5 that moves left and right along the mobile platform 17, an inner cylinder 3 is independently installed in the outer cylinder 5, an elastomer 4 is arranged between the inner cylinder 3 and the outer cylinder 5, the right end of the inner cylinder 3 is sealed with a refueling gun nozzle 2, and the left end of the inner cylinder 3 is the oil inlet end. A moving assembly that pushes the outer cylinder 5 toward or away from the guide seat 1 is installed on the mobile platform 17; the moving assembly adopts existing technologies such as hydraulic cylinders, air cylinders or electric push rods that can achieve reciprocating motion.

[0039] The right end of the outer cylinder 5 is installed with a right end cover 16 for preventing the elastic body 4 from going out from the right, and the left end of the outer cylinder 5 is installed with a left end cover 6 for preventing the elastic body 4 from going out from the left.

[0040] An oil filling chamber 12 is installed at the left end of the inner cylinder 3, and a through hole communicating with the inner cylinder 3 is opened on the oil filling chamber 12. A blocking bead 13 is set in the inner cylinder 3 to seal the through hole, and a return spring 15 is installed in the inner cylinder 3 to seal the blocking bead 13 at the through hole; in order to improve the sealing effect of the blocking bead 13, the return spring 15 is preferably a conical spring.

[0041] When installed, one end of the return spring 15 is fixed to the inner tube 3 , and the other end is fixed to the blocking bead 13 .

[0042] The oil filling chamber 12 is connected to the oil pump 7 through a pipeline. When the pipeline is long enough, the oil pump 7 can be installed on the ground. Of course, the oil tank can also be directly installed on the mobile platform 17, and the oil pump 7 can be installed on the mobile platform 17.

[0043] A following assembly 18 is provided on the mobile platform 17 to enable the mobile platform 17 to follow the guide seat 1 when refueling. The following assembly 18 includes a following platform. The distance from the guide seat 1 to the mobile platform 17 is smaller than the distance from the following platform to the mobile platform 17. A following adjustment assembly 20 is installed on the mobile platform 17 to enable the following platform to move left and right. Figure 5The following adjustment component 20 shown can adopt existing technologies such as hydraulic cylinders, air cylinders or electric push rods that can achieve reciprocating motion. This configuration uses a hydraulic cylinder, the cylinder body of the hydraulic cylinder is installed on the mobile platform 17, and the piston rod of the hydraulic cylinder is installed on the following platform. The following platform and the mobile platform 17 are in left-right sliding cooperation. Figure 6 As shown, the hydraulic cylinder is installed on the outer cylinder 5, and the specific installation method is determined according to the space conditions.

[0044] In order to facilitate the reset of the mobile platform 17, the corresponding mobile platform 17 is provided with a reset component for resetting the mobile platform 17 after movement. There are many solutions to achieve this function in the prior art, such as through the cooperation of the screw rod and the nut, and the conveyor chain. This embodiment adopts Figure 1 In the scheme shown, the reset assembly includes a gear 8 and a rack 10 that mesh with each other, wherein the rack 10 is installed along the front and rear direction of the mobile platform 17, and a motor 9 is installed on the ground corresponding to the gear 8. The gear 8 is installed on the output shaft of the motor 9. During installation, if the height of the motor 9 is not enough, a mounting base needs to be installed under the motor 9.

[0045] When following, the guide seat 1 pushes the following stage, and the following stage drives the mobile platform 17 to follow and move, and the motor 9 does not work and idles; when resetting, the motor 9 is started to drive the gear 8, and with the cooperation of the gear 8 and the rack 10, the mobile platform 17 is reset.

[0046] When selecting the guide seat 1, the guide seat 1 satisfies the following formula:

[0047] Fsinα-μFCosα>0

[0048] Wherein, F is the thrust exerted on the outer cylinder 5; μ is the coefficient of static friction; and α is the inclination angle of the inner surface at the small end of the oil filling hole 19.

[0049] The elastic coefficient k of the elastic body 4 satisfies the following formula:

[0050]

[0051] Wherein, k is the elastic coefficient of the elastic body 4, in N / mm; Figures 1 to 4 As shown, B is the maximum offset value. Usually, under mechanical positioning and visual positioning, the maximum deviation does not exceed 3mm, and the value of B is not less than 3mm.

[0052] like Figure 4 As shown, F is the thrust exerted on the outer cylinder 5, in N; α is the inclination angle of the inner surface at the small end of the oil filling hole 19.

[0053] When using, Figures 1 to 3As shown, when the refueling gun nozzle 2 cannot be directly aligned with the oil filling hole 19, that is, when there is a deviation in the positioning of the refueling gun nozzle 2, when the refueling gun nozzle 2 is moved toward the guide seat 1 and contacts thereafter, the refueling gun nozzle 2 is pressed on the guide seat 1. Under the action of friction, and due to the conical structure of the oil filling hole 19 and the design of the elastomer 4, the refueling gun nozzle 2 will slide along the surface of the oil filling hole 19 to the small mouth of the oil filling hole 19. During the sliding process, the elastomer 4 will deform, and the refueling gun nozzle 2 can swing radially moderately. The oil filling hole 19 will guide the refueling gun nozzle 2 to move to the position of the bottom of the cone (i.e., the refueling hole), and finally achieve precise positioning.

[0054] In order to realize automatic refueling, a contact switch is installed on the following platform, which is triggered when the guide seat 1 contacts the following platform. When the contact switch sends a contact signal, the moving component starts to push the outer tube 5 toward the guide seat 1. When the oil outlet end of the oil filling hole 19 detects the refueling gun nozzle 2 (to complete this function, a detection sensor or contact switch needs to be installed at the oil outlet end of the oil filling hole 19), the pushing stops and the refueling work starts. After refueling, the outer tube 5 is driven away from the guide seat 1 by the moving component.

[0055] Example 2

[0056] This embodiment mainly describes a design of a fueling gun guide seat, which includes a seat body, a fueling hole (i.e., a fueling hole) for fueling the sintering table wheel. Figure 4 The oil filling hole 19) has a cone-shaped structure as a whole, wherein the small end is used to add oil to the sintering trolley wheel, and the large end is used to guide the oil filling nozzle into the oil filling hole.

[0057] When using this design, the base is first installed at the refueling port of the sintering platform wheel, so that the refueling hole and the sintering platform wheel refueling port are sealed and connected. This makes refueling convenient for workers and improves the alignment efficiency between the oil gun and the refueling hole when refueling. At the same time, if mechanical refueling is used, when there is a position difference between the refueling gun and the refueling port of the sintering platform wheel, or when the sintering platform wheel runs unsteadily during refueling, the cone-shaped refueling hole design can compensate for the position difference within a certain range. This range depends on the elastic deformation of the refueling gun without being damaged. It also prevents the occurrence of gun detachment and oil leakage caused by unsteady running of the sintering platform wheel. Common phenomena of unsteady running of the sintering platform wheel include up and down bumps or uneven running speed.

[0058] Example 3

[0059] like Figures 1 to 3The relevant drawings shown in the figure mainly illustrate the design of a positioning fueling gun, the structure of which includes a horizontally arranged outer cylinder 5, an inner cylinder 3 independently installed in the outer cylinder 5, an elastomer 4 is arranged between the inner cylinder 3 and the outer cylinder 5, the right end of the inner cylinder 3 is sealed and connected to the fueling gun nozzle 2, and the left end of the inner cylinder 3 is the oil inlet end; the elastomer 4 can be an integral rubber sleeve, or it can be filled with rubber particles, and other structures such as springs can also be used, as long as the angle adjustment of the fueling gun nozzle 2 can be achieved.

[0060] An oil filling chamber 12 is installed at the left end of the inner cylinder 3, and a through hole communicating with the inner cylinder 3 is opened on the oil filling chamber 12. A blocking ball 13 is set in the inner cylinder 3 to seal the through hole, and a return spring 15 is installed in the inner cylinder 3 to seal the blocking ball 13 at the through hole. The oil filling chamber 12 is provided with an oil inlet; preferably, the return spring 15 is a conical spring.

[0061] The right end of the outer cylinder 5 is installed with a right end cover 16 for preventing the elastic body 4 from going out from the right, and the left end of the outer cylinder 5 is installed with a left end cover 6 for preventing the elastic body 4 from going out from the left.

[0062] During use, if there is a position difference between the refueling nozzle 2 and the refueling port of the sintering platform wheel, or if the sintering platform wheel runs unsteadily during the refueling process, the sintering platform wheel usually runs unsteadily, such as up and down bumps or uneven speed. Under the action of this design, it can be compensated, thereby further ensuring the service life of the refueling nozzle 2.
