[0001] The utility model relates to the technical field of railway freight car equipment, in particular to an intelligent matching and positioning device for a bogie bolster spring. Background Art

[0002] Currently, the bogie bolster springs on the bogie bolster spring line need to be grasped by a bolster spring matching robot. Due to the limited grasping range of the bolster spring matching robot, the bogie bolster springs need to be accurately moved to the intelligent matching station to facilitate the grasping of the bolster spring matching robot.

[0003] The existing technology typically uses a manual lifting pallet to lift the bogie bolster springs to the intelligent matching station. However, this lifting method easily causes radial wobble in the bogie bolster springs during lifting, making it difficult to accurately move the bogie bolster springs to the pre-set intelligent matching station and inconvenient for the bogie bolster spring matching robot to grasp them. This results in low bogie bolster spring matching efficiency.

[0004] In other words, the prior art has the problem of low efficiency in selecting and matching bogie bolster springs. Utility Model Content

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] like Figure 1 and Figure 2As shown, the present invention provides a bogie bolster spring intelligent matching and positioning device, which includes a base 10, a lifting mechanism 20, a straightening assembly 30, and a tray 40. The base 10 is fixed to an external base 200; the lifting mechanism 20 is slidably connected to the base 10 in a first direction (the height direction of the bogie bolster spring intelligent matching and positioning device); the straightening assembly 30 is disposed on the lifting mechanism 20; and the tray 40 is placed on the base 10. The tray 40 is spaced apart from the base 10 in the first direction and is located above the straightening assembly 30. The tray 40 is used to hold the bogie bolster spring 100. The lifting mechanism 20 can drive the straightening assembly 30 to move upward in the first direction, pass through the tray 40, and extend into the bogie bolster spring 100 to straighten the bogie bolster spring 100. The lifting mechanism 20 can lift the tray 40 in the first direction to a preset position so that the bolster spring matching robot can grasp the bogie bolster spring 100.

[0040] In the above arrangement, the bogie bolster spring 100 can be straightened using the straightening assembly 30, and then the lifting mechanism 20 can be used to lift the bogie bolster spring 100 to a preset position, i.e., the intelligent bogie bolster spring matching station. This improves the efficiency of bogie bolster spring matching and effectively saves time.

[0041] Specifically, if Figure 3 and Figure 4 As shown, in one embodiment, the lifting mechanism 20 includes a lifting base 21 and at least one guide post 22. The lifting base 21 is provided with a straightening assembly 30; the at least one guide post 22 is provided through the bottom end of the lifting base 21 along a first direction; and the at least one guide post 22 is slidably connected to the base 10 in the first direction.

[0042] Specifically, if Figure 3 As shown, in one embodiment, the lifting mechanism 20 includes two guide posts 22. The two guide posts 22 are relative to the center line of the lifting base 21 in the second direction ( Figure 3 The two axes are set symmetrically in the horizontal direction.

[0043] Specifically, if Figure 3 and Figure 4 As shown, in one embodiment, the base 10 includes a body 11 and at least one fixing sleeve 12. The body 11 is fixed to the external base 200; and the at least one fixing sleeve 12 is fixed to the body 11. At least one guide post 22 is disposed in the at least one fixing sleeve 12 along a first direction and is slidably connected to the at least one fixing sleeve 12.

[0044] Specifically, if Figure 3As shown, in one embodiment, the base 10 includes a body 11 and two fixing sleeves 12. The body 11 is fixed to the external base 200; and the two fixing sleeves 12 are fixed to the body 11, and the two guide pillars 22 are respectively inserted into the two fixing sleeves 12 along the first direction.

[0045] Specifically, if Figure 3 and Figure 4 As shown, in one embodiment, a linear bearing 13 is provided between the fixing sleeve 12 and the guide column 22 , and the linear bearing 13 is fixed on the fixing sleeve 12 .

[0046] In the above arrangement, the linear bearing 13 can prevent the fixing sleeve 12 and the guide post 22 from directly contacting each other, thereby avoiding the sliding friction generated by the direct contact between the two, thereby improving the sliding efficiency between the fixing sleeve 12 and the guide post 22.

[0047] It should be noted that in the present application, the linear bearing 13 is in direct contact with the guide post 22 , and the rolling friction between the two improves the sliding efficiency of the guide post 22 in the fixed sleeve 12 .

[0048] Specifically, if Figures 1 to 5 As shown, in one embodiment, the straightening assembly 30 includes at least one bolster spring positioning shaft 31, and the at least one bolster spring positioning shaft 31 can extend into a corresponding bogie bolster spring 100 placed on the tray 40 to straighten the bogie bolster spring 100.

[0049] Specifically, if Figure 1 、 Figure 2 and Figure 5 As shown, in one embodiment, the centralizing assembly 30 includes nine pillow spring positioning shafts 31 arranged in a rectangular pattern.

[0050] Specifically, if Figure 1 、 Figure 2 and Figure 5 As shown, in one embodiment, the tray 40 includes a plate body 41 and nine positioning sleeves 42. The plate body 41 is provided with nine through-holes 411, through which nine bolster spring positioning shafts 31 extend in a one-to-one correspondence. The positioning sleeves 42 are disposed on the plate body 41 and are concentric with the corresponding through-holes 411. The bogie bolster spring 100 includes an inner spring 101 and an outer spring 102 sleeved around the outer periphery of the inner spring 101. The outer spring 102 is positioned within the positioning sleeves 42. The bolster spring positioning shafts 31 are used to straighten the inner spring 101.

[0051] It should be noted that the positioning sleeve 42 is used to position the outer spring 102, and the pillow spring positioning shaft 31 is used to straighten the inner spring 101. This ensures that the lifting mechanism 20 can accurately lift the bogie pillow spring 100 to the matching position to facilitate the pillow spring matching robot to grab it.

[0052] Specifically, if Figure 3 As shown, in one embodiment, the bogie pillow spring intelligent matching and positioning device also includes a driving mechanism 50, which is fixed on the base 10 and connected to the lifting mechanism 20, and the driving mechanism 50 is used to drive the lifting mechanism 20 to move in the first direction.

[0053] Specifically, if Figure 3 As shown, in one embodiment, the driving mechanism 50 is a hydraulic cylinder, the fixed end of the hydraulic cylinder is fixed on the base 10 , and the driving end of the hydraulic cylinder is connected to the lifting mechanism 20 .

[0054] Of course, in an alternative implementation not shown in the drawings of the present application, the driving mechanism 50 uses an electric push rod, the fixed end of the electric push rod is fixed to the base 10, and the driving rod of the electric push rod is connected to the lifting mechanism 20.

[0055] Specifically, in one embodiment, a control device is further included. The control device is electrically connected to the driving mechanism 50 . The control device controls the driving mechanism 50 to move so as to control the lifting mechanism 20 to move upward and downward.

[0056] It should be noted that in this application, when the pallet with the bogie bolster springs reaches the selection station, the blocker is raised to block the pallet, the lifting mechanism is lifted, and the bolster spring positioning shaft passes through the pallet's process hole (through hole). The guide cone on the bolster spring positioning shaft adjusts the inner spring, and the inner spring drives the outer spring to move synchronously, thereby achieving precise positioning of the bogie bolster spring, facilitating the bolster spring selection robot to grasp the inner or outer spring to be replaced. Because the bolster spring positioning shafts correspond one-to-one with the number of bolster spring pallet retaining rings (positioning sleeves), up to nine sets of bogie bolster springs can be positioned simultaneously, that is, all bogie bolster springs on the pallet can be precisely positioned in a single action.

[0057] It should be noted that, since the inner diameters of the inner springs of various types of freight car bogie bolsters are different, ranging from φ47mm to φ58mm, the guide column diameter of the utility model adopts φ45mm, which can adapt to the selection of bolster springs of various types of freight car bogies.

[0058] The device of the utility model has the following characteristics:

[0059] 1. The precise positioning of the bogie bolster spring at the selection station is realized.

[0060] 2. Effectively improve the efficiency of online intelligent matching of bogie bolster springs and reduce labor costs.

[0061] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
