Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a visual drilling device for a bearing ring. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft, and the function of the outer ring is to cooperate with the bearing seat and play a supporting role. In the processing of some bearings, it is necessary to drill the outer ring of the bearing, that is, the ferrule, so that the lubricating oil can enter the bearing through the hole to achieve a better lubrication effect.

[0003] Existing bearing drilling devices usually use several drilling mechanisms to drill bearing rings, but the positions of the drilling mechanisms are usually fixed and cannot be changed, which results in that the spacing and relative positions of the holes processed once cannot be changed. When the distance or relative position between the holes needs to be adjusted, the movement of the fixture needs to be controlled to change the positional relationship between the holes, but this makes it difficult for multiple drilling mechanisms to work at the same time, and some bearing drilling devices have more complicated structures, which will block the bearing rings to varying degrees during the drilling process, making it inconvenient for workers to observe the drilling situation with the naked eye or using industrial cameras. Therefore, in response to the above problems, a visual drilling device for bearing rings is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a visual drilling device for a bearing ring, the drilling device is provided with a plurality of movable bases which can rotate with the bearing ring installation position as the rotating axis, and a drilling mechanism is provided on each movable base. When it is necessary to change the spacing or position relationship between the holes, it can be achieved by simply rotating the movable base to change the relative position relationship between the drilling mechanisms, and the number of movable bases can be increased or decreased within a certain range to meet different needs. At the same time, the setting method of the drilling mechanism has a small shielding effect on the bearing ring, which can facilitate workers to observe the drilling situation with the naked eye or an industrial camera, thereby solving the technical problems in the prior art where the relative position relationship between the drilling mechanisms is difficult to adjust, resulting in inconvenience in use and inconvenience in visual operation during the drilling process.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A visual drilling device for a bearing ring comprises a chassis, an upper end surface of which is provided with an inner guide rail, a limiting groove and an outer guide rail in sequence from the inside to the outside, a movable base, which is movably arranged on the chassis and can drive the drilling mechanism thereon to rotate, and a bearing clamp for clamping the bearing ring to be processed, wherein the movable base comprises a movable plate, a lower end surface of which is fixedly provided with an inner guide ring segment and an outer guide ring segment in sequence from the inside to the outside, the inner guide ring segment is slidably arranged in the inner guide rail, the outer guide ring segment is slidably arranged in the outer guide rail, and limiting members are fixedly arranged on both sides of the movable plate.

[0007] Through the above-mentioned structural form, the inner guide rail and the outer guide rail respectively constrain the inner guide ring segment and the outer guide ring segment to slide in the corresponding rail grooves, so as to constrain several movable bases to rotate with the installation position of the bearing ring, that is, the setting position of the bearing fixture as the rotating axis, and then adjust the relative position relationship between the drilling mechanisms, so that the relative position relationship between the holes formed by the processing can be adjusted, and the number of movable bases can be increased or decreased within a certain range to meet different needs; at the same time, the setting method of the drilling mechanism has a small shielding effect on the bearing ring, which can facilitate workers to observe the drilling situation with the naked eye or an industrial camera, and facilitate visual operation.

[0008] In one possible implementation, a centrally arranged pointer is fixedly provided on the outer end surface of the movable plate, a scale groove is opened at the outer edge of the upper end surface of the chassis, annular scale lines are drawn in the scale groove, the pointer points to the annular scale lines, and corresponds one-to-one with the scale of the annular scale lines during the rotation process.

[0009] With the above structure, when the movable plate is rotated, the pointer will rotate synchronously. At this time, the positional relationship between the pointer and the scale lines in the scale groove or the current rotation amplitude can be used to improve the accuracy of adjustment.

[0010] In one possible implementation, the limiting member includes a locking shaft and a fastening ear, wherein the bottom of the locking shaft is slidably engaged in the limiting groove, the fastening ear is provided with a through mounting hole, the upper portion of the locking shaft is inserted into the mounting hole, and the top of the locking shaft is threadedly connected to a locking wheel.

[0011] Through the above-mentioned structural form, when the movable plate rotates, the locking shaft can synchronously follow and slide in the limiting groove. When the position adjustment of the movable plate is completed, the locking wheel is turned to increase the friction force between the locking wheel and the bottom of the locking wheel through the clamping action between the locking wheel and the limiting groove, thereby fixing the movable plate.

[0012] In a possible implementation, the cross-sectional width of the inner guide ring segment is consistent with the cross-sectional width of the inner guide rail, and the cross-sectional width of the outer guide ring segment is consistent with the cross-sectional width of the outer guide rail.

[0013] Through the above-mentioned structural form, the inner guide ring segment can fit tightly with the inner guide rail, and the outer guide ring segment can fit tightly with the outer guide rail, thereby ensuring that the movable plate does not shake when rotating and ensuring the uniqueness of the rotating shaft.

[0014] In one possible implementation, the drilling mechanism includes a mounting frame fixedly mounted on a movable plate, a cylinder is fixedly mounted on the rear side of the upper end surface of an upper horizontal plate of the mounting frame, a drilling machine is fixedly connected to the output shaft end of the cylinder, and a detachable drill bit is mounted on the front end of the drilling machine.

[0016] In a possible implementation, support seats are fixedly provided on both sides of the upper end surface of the upper horizontal plate of the mounting frame, a guide rod is fixedly provided on the top of the support seat, two groups of guide sleeves are provided on the sliding sleeve of the guide rod, and the ends of the guide sleeves are fixedly connected to the side walls of the drilling machine.

[0017] The above structure can support and install the drilling machine, share its vertical load without hindering the forward and backward movement of the drilling machine, and prevent the cylinder shaft end from being subjected to a large bending moment that affects its normal operation.

[0018] In a possible implementation, a gap is left between the lower end surface of the drilling machine and the upper end surface of the upper horizontal plate of the mounting frame.

[0019] The above-mentioned structural form can avoid friction between the lower end surface of the drilling machine and the upper horizontal plate of the mounting frame, and can ensure that the drilling machine is subject to as little obstruction as possible during the forward and backward movement.

[0020] In a possible implementation, a circular through hole is opened in the middle of the chassis, and the bearing fixture is arranged at the center of the through hole opened in the middle of the chassis.

[0021] The above structure ensures that all drilling mechanisms can use the bearing fixture as the rotation axis during the rotation process, that is, the drilling mechanism uses the bearing ring fixed on the bearing fixture as the rotation center, which facilitates the drilling process.

[0022] In summary, the utility model includes the following beneficial technical effects:

DETAILED DESCRIPTION

[0031] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0032] like Figure 1 - Figure 2As shown, a visual drilling device for a bearing ring provided in this embodiment includes a chassis 1, an inner guide rail 11, a limiting groove 13 and an outer guide rail 12 are sequentially opened on the upper end surface from the inside to the outside, a movable base 2, which is movably arranged on the chassis 1, a drilling mechanism 3, which is installed on the movable base 2, and a bearing fixture 4. Through the above-mentioned structural form, a plurality of movable bases 2 are rotated with the installation position of the bearing ring, that is, the setting position of the bearing fixture 4 as the rotating axis, and then the relative position relationship between the drilling mechanisms 3 is adjusted, so that the relative position relationship between the holes formed by the processing is adjustable, and the number of movable bases 2 can be increased or decreased within a certain range to meet different needs. At the same time, the setting method of the drilling mechanism 3 has a small shielding effect on the bearing ring, which can facilitate workers to observe the drilling situation with naked eyes or industrial cameras, and facilitate the implementation of visual operations.

[0033] Among them, the movable base 2 includes a movable plate 21, and the lower end surface of the movable plate 21 is fixedly provided with an inner guide ring segment 22 and an outer guide ring segment 23 in sequence from the inside to the outside. The inner guide ring segment 22 is slidably set in the inner guide rail 11, and the outer guide ring segment 23 is slidably set in the outer guide rail 12. Limiting members 25 are fixedly set on both sides of the movable plate 21. Through the above-mentioned structural form, the inner guide rail 11 and the outer guide rail 12 respectively constrain the inner guide ring segment 22 and the outer guide ring segment 23 to slide in the corresponding rail grooves, thereby realizing the constraint of several movable bases 2 to rotate with the installation position of the bearing ring, that is, the setting position of the bearing fixture 4 as the rotating axis, providing the necessary structural basis for adjusting the relative position relationship between the drilling mechanisms 3.

[0034] In particular, the cross-sectional width of the inner guide ring segment 22 is consistent with the cross-sectional width of the inner guide rail 11, and the cross-sectional width of the outer guide ring segment 23 is consistent with the cross-sectional width of the outer guide rail 12. This structural form can make the inner guide ring segment 22 fit tightly with the inner guide rail 11, and the outer guide ring segment 23 fit tightly with the outer guide rail 12, thereby ensuring that the movable plate 21 will not shake during rotation, ensuring the uniqueness of the rotating shaft.

[0035] like Figure 2 As shown, a centrally arranged pointer 24 is fixedly provided on the outer end surface of the movable plate 21, and a scale groove 14 is opened at the outer edge of the upper end surface of the chassis 1, and annular scale lines are drawn in the scale groove 14. Through the above-mentioned structural form, when the movable plate 21 is rotated, the pointer 24 will follow the rotation synchronously. At this time, the positional relationship between the pointer 24 and the scale lines in the scale groove 14 or the current rotation amplitude can be used to improve the accuracy of adjustment.

[0036] like Figure 3As shown, the limiting member 25 includes a locking shaft 251 and a fastening ear 252, wherein the bottom of the locking shaft 251 is slidably engaged in the limiting groove 13, and the fastening ear 252 is provided with a through mounting hole 253, the upper part of the locking shaft 251 is inserted in the mounting hole 253, and the top of the locking shaft 251 is sleeved with a threaded locking wheel 254. Through the above-mentioned structural form, when the movable plate 21 rotates, the locking shaft 251 can synchronously follow the sliding in the limiting groove 13. When the position adjustment of the movable plate 21 is completed, the locking wheel 254 is turned, and the clamping effect between the locking wheel 254 and the bottom of the locking wheel 254 increases the friction between the limiting groove 13, thereby fixing the movable plate 21.

[0037] like Figure 4 As shown, the drilling mechanism 3 includes a mounting frame 31 fixedly arranged on the movable plate 21, a cylinder 37 is fixedly arranged on the rear side of the upper end surface of the upper horizontal plate of the mounting frame 31, a drilling machine 35 is fixedly connected to the output shaft end of the cylinder 37, and a detachable drill bit 36 ​​is installed at the front end of the drilling machine 35. Through the above-mentioned structural form, the drilling machine 35 can be driven by the cylinder 37 to move forward and backward, thereby completing the process of advancing drilling and retreating drilling, and this form can be suitable for drilling work of bearing rings of different sizes.

[0038] At the same time, support seats 32 are fixedly arranged on both sides of the upper end surface of the horizontal plate on the upper part of the mounting frame 31, and a guide rod 33 is fixedly arranged on the top of the support seat 32. Two sets of guide sleeves 34 are provided on the sliding sleeve of the guide rod 33. The ends of the guide sleeves 34 are fixedly connected to the side walls of the drilling machine 35. Through the above-mentioned structural form, the drilling machine 35 can be supported and installed, and its vertical load can be shared without hindering the forward and backward movement of the drilling machine 35, so as to avoid the axial end of the cylinder 37 being subjected to a large bending moment and affecting its normal operation.

[0039] In particular, when the drill 35 is slidably set between the guide rods 33 through the guide sleeve 34, a gap is left between the lower end surface of the drill 35 and the upper end surface of the upper horizontal plate of the mounting frame 31. The above-mentioned structural form can avoid friction between the lower end surface of the drill 35 and the upper horizontal plate of the mounting frame 31, and can ensure that the drill 35 is subject to as little obstruction as possible during the forward and backward movement.

[0040] like Figure 1 As shown, a circular through hole is opened in the middle of the chassis 1, and the bearing fixture 4 is arranged at the center of the through hole opened in the middle of the chassis 1, and the central axis of the bearing fixture 4 coincides with the central axis of the chassis 1. Through the above-mentioned structural form, it can be ensured that all drilling mechanisms 3 can use the bearing fixture 4 as the rotation axis during the rotation process, that is, the drilling mechanism 3 uses the bearing ring fixed on the bearing fixture 4 as the rotation center, which is convenient for drilling processing.

[0041] The use principle and use process of this utility model:

[0042] By means of the inner guide rail 11 and the outer guide rail 12 respectively constraining the inner guide ring segment 22 and the outer guide ring segment 23 to slide in the corresponding rail grooves, it is possible to constrain several movable bases 2 to rotate with the installation position of the bearing ring, that is, the setting position of the bearing fixture 4 as the rotating axis, and then adjust the relative position relationship between the drilling mechanisms 3, so that the relative position relationship between the holes formed by the processing can be adjusted, and the number of movable bases 2 can be increased or decreased within a certain range to meet different needs; and in the adjustment process, when the movable plate 21 is rotated, the pointer 24 will follow the rotation synchronously. At this time, the position relationship between the pointer 24 and the scale line in the scale groove 14 or the current rotation amplitude can be used to improve the accuracy of the adjustment.

[0043] At the same time, the arrangement of the drilling mechanism 3 has little shielding effect on the bearing ring, which makes it easy for workers to observe the drilling situation with the naked eye or an industrial camera, thereby facilitating visual operations.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
