Description

Technical Field

[0001] The utility model relates to the technical field of a floating tooling device for vertical honing. Background Art

[0002] Honing is a type of grinding. Different from the rigid clamping method of internal grinding, it is a flexible processing. Because there is no way to ensure the precise concentricity of the honing head and the hole, it is made into a floating method, or the honing head floats, or the parts float, in order to prevent the honing head and the parts from getting stuck during processing.

[0003] The existence of floating means the existence of processing tolerance, and most of the current technologies are air floating. The floating platform is easily balanced by the force applied during honing. In addition, the tolerance generated during the processing of the floating platform causes the quality of the processed product to exceed the tolerance of the product, causing economic losses. In order to improve the processing accuracy of the equipment and avoid honing jamming or tool damage, this application is proposed. Utility Model Content

[0004] The utility model aims to provide a honing floating tooling to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0025] See also Figures 1 to 6 In the embodiment of the utility model, a honing floating tooling comprises a control end, a floating platform 1 and a floating base 2. The lower half of the floating platform 1 is mounted on the top of the floating base 2. There is a gap for floating between the floating platform 1 and the floating base 2. A bull's eye bearing 3 is installed on the floating base 2. The floating platform 1 is movably installed on the top of the floating base 2. Through the bull's eye bearing 3, the floating platform 1 can float on the top of the floating base 2. The floating platform 1 performs floating processing on the top of the floating base 2 through the bull's eye bearing 3. During the installation process, the bull's eye bearing 3 is measured by a level meter to keep it at the same level. After the floating platform 1 is installed, a secondary level meter measurement is performed to ensure that it is stable during the floating process or within the allowable error range. Compared with air floating, the floating mode of the bull's eye bearing 3 can also keep the floating platform 1 horizontal when weighing and bearing asymmetric and unbalanced forces, and has strong load-bearing capacity and stable operation, but there is wear, and it is necessary to jack up and measure its floating horizontal state to ensure the stability of processing floating.

[0026] In a preferred embodiment, a countersunk hole is provided on the top of the floating base 2, and the bull's eye bearing 3 is located in the countersunk hole. An oil guide groove 4 connecting the countersunk holes is opened on the top of the floating base 2, and the bull's eye bearing 3 is installed inside the countersunk hole. The countersunk holes are connected through the oil guide groove 4 so that the lubricating oil inside them can flow to each other.

[0027] In a preferred embodiment, a lubricating oil pipeline 6 connected to the oil guide groove 4 or the countersunk hole is installed at the bottom of the floating base 2. The lubricating oil pipeline 6 is connected to the pump body. The lubricating oil can be circulated or added through the lubricating oil pipeline 6 to maintain the lubrication effect and reduce structural wear.

[0028] In a preferred embodiment, the floating base 2 is equipped with a floating air pipe 5 that can blow the floating platform 1 horizontally by gas. The floating air pipes 5 are distributed in a circular shape with equal distances, and the bottom end is connected to the air blowing pipeline 7. The floating air pipe 5 is equipped with an air valve 12. The floating cannot achieve a control effect. When some areas require key honing or deviation correction, the dynamic processing of the floating platform will result in the inability to hone the key areas. For this reason, air pressure is supplied inward through the floating air pipe 5, and the gas flexibly blows the floating platform 1 to deviate in the specified direction, so that the key honing area is effectively processed. Multiple floating air pipes 5 can cooperate with each other to guide the floating platform 1 in different directions, and the flexible air push method can also avoid excessive collisions that cause damage to the oilstone.

[0029] In a preferred embodiment, the air valve 12 is connected to the control end by electrical signals, and the control end controls the opening and closing of the air valve 12. The control end is a prior art and will not be described in detail here. The control end controls the air circuit and controls the guidance of the floating platform 1 to achieve precise and intelligent honing processing.

[0030] In a preferred embodiment, a floating locating member 8 is installed on the floating base 2, which can slide outward to push the floating platform 1 to a central position. The floating locating members 8 are distributed in a circular shape with equal distances. During the floating honing process, the dynamic honing method enlarges the internal pores of the workpiece, thereby reducing the risk of jamming during the honing process. After the floating platform 1 is corrected by blowing gas, the rough honing section is basically completed and the fine honing begins. At this time, the dynamic floating processing will only affect the honing accuracy. In order to improve the accuracy, the floating platform 1 is positioned by the floating locating member 8 during the honing process or before honing to avoid the influence of floating on the processing accuracy and improve the product accuracy.

[0031] In a preferred embodiment, a lifting component 9 that can move vertically up and down is installed inside the floating base 2, and a cylinder 10 is installed between the lifting component 9 and the floating base 2. The surfaces where the floating positioning member 8 and the lifting component 9 contact each other are both chamfered surfaces. When the cylinder 10 pushes the lifting component 9 to move upward, the chamfered surface pushes the floating positioning member 8 outward to fix the position of the floating platform 1. This driving method is to drive multiple floating positioning members 8 to work synchronously through the lifting component 9 to achieve a centering positioning effect. A spring that pushes the floating positioning member 8 to one side of the lifting component 9 is installed in the floating positioning member 8 to keep the lifting component 9 in a retracted state. The air inlet end of the cylinder 10 is connected to the air source pipeline 11, and the exhaust end of the cylinder 10 is connected to the exhaust pipeline. Both the air source pipeline 11 and the exhaust pipeline are provided with control valves. The air sources of the air source pipeline 11 and the exhaust pipeline come from the air pump to provide sufficient air pressure.

[0032] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.

[0033] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
