DETAILED DESCRIPTION

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0029] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] The main bearing is one of the core parts of the tunnel boring machine. The geological environment in which the tunnel boring machine works is complex and changeable. The main bearing mainly bears the huge complex alternating loads and overturning moments generated by the tunnel boring machine during excavation. Since the actual working condition of the tunnel boring machine is that it can only move forward but not backward, and the underground excavation space is extremely limited, once the main bearing is damaged, it is difficult to replace it, which will directly lead to the paralysis of the tunnel boring machine and cause significant economic losses. Therefore, the quality of the main bearing of the tunnel boring machine is extremely important for providing the performance of the tunnel boring machine.

[0031] Among them, the radial cage of the main bearing of the tunnel boring machine is thin and has poor rigidity, and multiple pockets need to be processed on the radial cage, which makes it difficult to clamp the radial cage and has poor clamping stability. When processing vertical or horizontal shafts, it not only makes the tool easily damaged, but also causes the surface of the radial cage to be pierced or have vibration marks.

[0032] In order to avoid the above-mentioned problems, the present application provides a bearing radial retainer processing tool, which can not only achieve the stability of the radial retainer clamping, thereby improving the processing efficiency and yield rate of the radial retainer, but also reduce the number of repeated clamping times required for the radial retainer to perform pocket processing, thereby improving the convenience of radial retainer processing.

[0033] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] See also Figure 1 and Figure 2 As shown, this embodiment provides a bearing radial retainer 100 processing tool, which is mainly used to clamp the radial retainer 100 of the bearing to improve the convenience and stability of the processing of the radial retainer 100.

[0035] Specifically, the machining tooling for the bearing radial retainer 100 of this embodiment includes a fixed base 200 and at least two fixed fasteners 220. The upper surface of the fixed base 200 is used to fit with the lower surface of the radial retainer 100 to support the radial retainer 100. The fixed base 200 is fixed at a position of the milling machine for mounting a workpiece. The radial retainer 100 is mounted on the fixed base 200 and processed by a tool. The fixed fastener 220 is detachably connected to the fixed base 200. The fixed fastener 220 is used to be detachably connected to the top and bottom of the radial retainer 100 to fix the radial retainer 100 on the fixed base 200, that is, the fixed fastener 220 fixes the radial retainer 100 from the top and bottom of the radial retainer 100, so that the radial retainer 100 does not shake during the processing, which helps to improve the processing effect of the radial retainer 100. At the same time, there is a machining gap between the fixing fastener 220 and the side surface of the radial retainer 100 , and the machining gap is used for a tool for machining the radial retainer 100 to enter.

[0036] Among them, Figure 1 and Figure 2 As shown, the radial retainer 100 is an arc-shaped structure. The top and bottom of the radial retainer 100 refer to the two end faces corresponding to the two ends of the bearing. Either of the two faces of the radial retainer 100 fits with the upper surface of the fixed base 200, which can increase the contact area between the fixed base 200 and the radial retainer 100, so that the radial retainer 100 can be better supported by the fixed base 200.

[0037] It is understandable that two or more fixing fasteners 220 may be provided, so as to effectively fix the radial retainer 100 , and this embodiment does not limit this.

[0038] Exemplarily, two fixing fasteners 220 are provided, which are disposed at both ends of the radial retainer 100 to fix the radial retainer 100 from both ends.

[0039] Exemplarily, three fixing fasteners 220 are provided, which are respectively disposed at both ends and the middle of the radial retainer 100 .

[0040] When processing the radial retainer 100, the radial retainer 100 is placed on the fixed base 200 so that the lower surface of the radial retainer 100 is in contact with the upper surface of the fixed base 200, so that the radial retainer 100 is stably supported by the fixed base 200, and then the radial retainer 100 is fixed to the fixed base 200 from the top and top of the radial retainer 100 by the fixing fasteners 220, so that the radial retainer 100 will not shake during the processing, which helps to improve the yield rate of the radial retainer 100 processing and can also provide a certain protective effect on the tool. A processing gap is reserved between the fixing fastener 220 and the side surface of the radial retainer 100. When the radial retainer 100 is processed by a tool, the tool can process the portion of the radial retainer 100 blocked by the fixing fastener 220 through the processing gap. That is, the processing of all the pockets of the radial retainer 100 can be completed without moving the fixing fastener 220, which greatly reduces the number of clamping times required for processing the pockets of the radial retainer 100, thereby improving the processing speed and convenience of the radial retainer 100.

[0041] For some possible implementations, see Figure 3 As shown, a positioning groove 240 is provided on the fixed base 200, and the positioning groove 240 is arranged in an arc shape, and the size of the positioning groove 240 is adapted to the size of the bottom of the radial retainer 100, so that the bottom of the radial retainer 100 can be inserted, so that the lower surface of the radial retainer 100 is fitted with the bottom surface of the positioning groove 240, and the position of the radial retainer 100 is limited by the positioning groove 240.

[0042] When clamping the radial retainer 100, since the size and shape of the positioning groove 240 are consistent with the bottom of the radial retainer 100, the radial retainer 100 can be positioned by directly inserting the bottom of the radial retainer 100 into the positioning groove 240, which can not only improve the fixing effect of the radial retainer 100, but also reduce the difficulty of aligning the radial retainer 100 and improve the processing efficiency of the radial retainer 100. At the same time, the positioning groove 240 can also be used as a detection tool for the radial retainer 100, which can verify whether the arc processing of the radial retainer 100 meets the technical requirements, which helps to reduce the investment in detection tooling for the radial retainer 100.

[0043] It is understandable that the positioning groove 240 can be a through groove with openings at both ends, so that the bottom of the radial retainer 100 can be inserted into the positioning groove 240. In order to detect the arc processing condition of the radial retainer 100 through the positioning groove 240, the tolerance of the inner and outer guide surfaces of the radial retainer 100 can be compressed by half as the processing size of the positioning groove 240. As long as the processing accuracy of the positioning groove 240 is guaranteed, the radial retainer 100 can be effectively detected through the positioning groove 240.

[0044] Furthermore, a positioning boss 210 is provided on the fixed base 200, and a positioning groove 240 is provided on the positioning boss 210. The depth of the positioning groove 240 is 2 mm to ensure that the radial retainer 100 can be effectively positioned and whether the arc processing of the radial retainer 100 meets the technical requirements can be detected.

[0045] At the same time, the positioning boss 210 is provided on the fixed base 200, and the positioning groove 240 is provided on the positioning boss 210, which helps to reduce the material used for the fixed base 200 and reduce the weight of the fixed base 200. Specifically, the positioning groove 240 needs to have a certain depth. If the fixed base 200 is set as a flat plate, the overall thickness of the fixed base 200 needs to be greatly increased. After the positioning boss 210 is provided, the size of the positioning boss 210 only needs to be slightly larger than the size of the radial retainer 100.

[0046] Furthermore, in order to further improve the strength of the positioning boss 210 , the cross section of the positioning boss 210 may be a trapezoid that is smaller at the top and larger at the bottom.

[0047] In some possible embodiments, the positioning boss 210 is provided with a mounting groove 230, and the mounting groove 230 is provided in a one-to-one correspondence with the fixing fastener 220, that is, one fixing fastener 220 is provided with one mounting groove 230, and the mounting groove 230 is located below the positioning groove 240 and arranged along the length direction of the positioning groove 240. At least one first connecting hole 250 is provided on the groove wall of the mounting groove 230, and the first connecting hole 250 is used to connect the mounting groove 230 with the positioning groove 240, that is, the first connecting hole 250 It is arranged on the groove wall of the installation groove 230 on one side close to the positioning groove 240, and one end of the fixing fastener 220 extends into the installation groove 230. The fixing fastener 220 is provided with a second connecting hole that cooperates with the first connecting hole 250. The first connecting hole 250 and the second connecting hole are both used to cooperate with the lifting hole 110 at the bottom of the radial retainer 100, so that the radial retainer 100 and the fixing fastener 220 are fixed on the positioning boss 210 by passing the screw through the second connecting hole and the first connecting hole 250 and then extending into the lifting hole 110.

[0048] It is understandable that a separate hole may be provided on the radial retaining frame 100 to cooperate with the first connecting hole 250 and the second connecting hole. However, in order to reduce the impact on the structure of the radial retaining frame 100 and improve the adaptability of the processing tooling, at least the first connecting hole 250 and the second connecting hole are made to correspond to the lifting hole 110 of the radial retaining frame 100.

[0049] When clamping the radial retainer 100, the bottom of the radial retainer 100 is placed in the positioning groove 240, and then one end of the fixing fastener 220 is extended to the top of the radial retainer 100, and the other end is extended into the mounting groove 230, and the first connecting hole 250 and the second connecting hole are opposite to the hanging hole 110 of the radial retainer 100, and then the fixing fastener 220 is connected to the top of the radial retainer 100, and the screws are passed through the second connecting hole and the first connecting hole 250 in turn and screwed into the hanging hole 110 of the radial retainer 100, so that the radial retainer 100 is fixed on the fixed base 200. On the one hand, the mounting groove 230 facilitates the detachable connection between the fixing fastener 220 and the fixed base 200, and on the other hand, it can play an auxiliary limiting role in the position of the fixing fastener 220, thereby further improving the stability of the clamping of the radial retainer 100.

[0050] It is understandable that the mounting groove 230 may be a through groove to facilitate operation by the staff.

[0051] In some possible implementations, the first connection hole 250 extends along the height direction of the positioning boss 210 , and the depth of the first connection hole 250 is greater than or equal to 10 mm.

[0052] Since the bottom of the radial retaining frame 100 contacts the bottom of the positioning groove 240, the bottom of the positioning groove 240 is the main force-bearing surface, and the depth of the first connecting hole 250 is greater than or equal to 10 mm, that is, the wall thickness between the bottom of the positioning groove 240 and the mounting groove 230 is greater than or equal to 10 mm, which can effectively improve its strength and also extend the contact surface between the screw and it, thereby improving the fixing effect.

[0053] Furthermore, the distance between the edge of the positioning boss 210 and the edge of the positioning groove 240 is greater than or equal to 20 mm, that is, the wall thickness of the edge of the positioning groove 240 is at least 20 mm, which ensures the strength of the positioning boss 210 and can also ensure that the width of the processing gap is at least 20 mm, which is convenient for the tool to process the radial retaining frame 100.

[0054] In some possible embodiments, the fixing fastener 220 includes a first fastener 221 and a second fastener 222, one end of the first fastener 221 extends to the top of the radial retainer 100 and is connected to the radial retainer 100, and the other end is detachably connected to the second fastener 222, and the second connecting hole is arranged at one end of the second fastener away from the first fastener 221.

[0055] In this embodiment, the fixing fastener 220 is configured as a first fastener 221 and a second fastener 222 that are separated from each other. When the radial retainer 100 is clamped, the second fastener 222 is first inserted into the mounting groove 230 with one end having the second connection hole, and then the second fastener 222, the fixing base 200 and the radial retainer 100 are locked by screws, and then the first fastener 221 is fixed to the top of the radial retainer 100, and then the first mouthpiece and the second fastener 222 are connected, so that the second fastener 222 tightens the first fastener 221, thereby fixing the radial retainer 100. This configuration can increase the adjustable margin between the first fastener 221 and the second fastener 222 through the structural design thereof, so as to adapt to the processing of radial retainers 100 of different heights and improve the adaptability of the processing tooling. In addition, this fixing method is also convenient for operation and reduces the difficulty of fixing the radial retainer 100.

[0056] It is understandable that the fixing fastener 220 may not be set as the first fastener 221 and the second fastener 222, but directly set as a U-shaped structure or the like. As long as one end can extend to the top of the radial retainer 100 and be connected to the radial retainer 100, and the other end can extend into the mounting groove 230 and be connected to the radial retainer 100 and the fixed base 200, this embodiment does not limit it here.

[0057] Furthermore, a third connecting hole 2214 is provided on the first fastener 221, and the third connecting hole 2214 is used to cooperate with the lifting hole 110 at the top of the radial retainer 100, so that the radial retainer 100 and the first fastener 221 can be fixed by a screw passing through the third connecting hole 2214 and extending into the lifting hole 110 at the top of the radial retainer 100. Therefore, there is no need to open additional holes on the radial retainer 100, and the connection between the radial retainer 100 and the first fastener 221 and the second fastener 222 can be achieved, thereby improving the convenience of clamping.

[0058] It is understandable that the first fastener 221 and the radial retainer 100 may also be connected in other ways, as long as the connection strength between the radial retainer 100 and the first fastener 221 is guaranteed to prevent the radial retainer 100 from shaking during the processing.

[0059] For some possible implementations, see Figure 4As shown, the first fastener 221 and the second fastener 222 both include a first connecting plate 2211, a second connecting plate 2212 and a third connecting plate 2213, the two ends of the second connecting plate 2212 are connected to the first connecting plate 2211 and the third connecting plate 2213 respectively, the first connecting hole 250 is provided on the first connecting plate 2211 of the second fastener 222, the third connecting hole 2214 is provided on the first connecting plate 2211 of the first fastener 221, the two third connecting plates 2213 are parallel to each other, and the two third connecting plates 2213 are parallel to each other. The connecting plates 2213 are connected by bolts. For radial retainers 100 of different heights, it is only necessary to adjust the tightness of the bolts between the two third connecting plates 2213 to change the height of the fixing fastener 220 composed of the first fastener 221 and the second fastener 222, so that it can adapt to radial retainers 100 of different heights. In addition, the bolts can also be used to ensure that the radial retainer 100 is pressed into the positioning groove 240 through the first fastener 221, thereby ensuring the fixing effect of the radial retainer 100.

[0060] Furthermore, the extension direction of the second connecting plate 2212 is consistent with the height direction of the radial retainer 100, so as to form a processing gap between the radial retainer 100 and the second connecting plate 2212, and the width of the processing gap is greater than or equal to 20 mm, thereby ensuring that the tool can be inserted into the processing gap to process the radial retainer 100.

[0061] Specifically, the two first connecting plates 2211 can be made parallel to each other, the two second connecting plates 2212 can be located on the same straight line, and the first connecting plate 2211 can be parallel to the third connecting plate 2213. Of course, the extension directions of the first connecting plate 2211 and the third connecting plate 2213 relative to the second connecting plate 2212 are opposite, that is, the first connecting plate 2211 extends in a direction close to the radial retaining frame 100, and the third connecting plate 2213 extends in a direction away from the radial retaining frame 100, that is, the first fastener 221 and the second fastener 222 both form a Z-shaped structure for easy operation by the staff.

[0062] It is understandable that the edge of the positioning boss 210 may also be abutted against the second connecting plate 2212 to enhance the limiting effect of the positioning fastener.

[0063] In general, the machining tooling for the bearing radial retainer 100 provided in the embodiment of the present application is mainly used for clamping the radial retainer 100 after the inner and outer diameter guide surfaces are machined to the specified size. When clamping, it is only necessary to put the bottom of the radial retainer 100 into the positioning groove 240, and then insert the first connecting plate 2211 of the second fastener 222 into the mounting groove 230, and fix the fixing base 200, the second fastener 222, and the radial retainer 100 by screws, and place the first connecting plate 2211 of the first fastener 221 in the radial retainer. The first fastener 221 is fixed to the radial retainer 100 by screws, and finally the third connecting plate 2213 of the first fastener 221 and the second fastener 222 is locked by bolts, and then the tool can be used for processing. A horizontal milling machine can be selected to process the pocket holes of the radial retainer 100, and the processing amount should not be too large to avoid tool vibration. Therefore, the radial retainer 100 fixed by the bearing radial retainer 100 processing tooling of the embodiment of the present application has at least the following advantages during processing:

[0064] 1. It can effectively prevent the radial retainer 100 from deforming during the processing and improve the processing yield rate;

[0065] 2. The radial cage 100 will not shake during the processing, which can ensure that the roughness of the pocket surface of the radial cage 100 meets the technical requirements;

[0066] 3. It can reduce the number of clamping times required for the radial cage 100 during the processing, and complete the processing of all pockets in one clamping;

[0067] 4. Reduce the difficulty of aligning the cage when it is fixed, and improve the processing efficiency;

[0068] 5. It can be used as a detection tool for the radial retainer 100, that is, the positioning groove 240 can be used to verify whether the arc processing of the radial retainer 100 meets the technical requirements, which helps to reduce the investment in the detection tool for the radial retainer 100;
