Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a drilling device for bearing manufacturing. Background Technology

[0002] Bearings mainly consist of raceways, rolling elements, and a cage. During the manufacturing process, the raceways, which serve as the rigid support of the bearing, have oil filling holes machined on their surface. These holes connect the internal raceways to the external lubrication interface, ensuring that grease is accurately delivered to the contact area between the rolling elements and the raceways, meeting lubrication and heat dissipation requirements. Depending on the bearing's size, speed, load, and application, one or more oil filling holes are typically provided to ensure adequate lubrication to all contact areas.

[0003] In related technologies, existing drilling devices generally consist of a clamping mechanism and a drilling mechanism. The clamping mechanism clamps the bearing race by bringing two clamping plates close to each other. Since the clamping method of the two clamping plates can only fix the bearing race from both sides, the constraint force on the bearing race in other directions is insufficient. This leads to the bearing race easily moving in the radial direction during the processing, which affects the drilling accuracy and quality. Moreover, thin-walled bearing races are at risk of slight deformation when clamped, which affects the processing quality of the bearing. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a drilling device for bearing production. By adopting a multi-directional support structure design, it provides limiting support from the inside of the bearing race, thereby enhancing the constraint force on the bearing race, preventing the bearing race from moving or deforming, and ensuring the processing quality of the bearing.

[0006] To achieve the above objectives, this utility model proposes a drilling device for bearing production, comprising a worktable, a support base, a mounting bracket, a clamping mechanism, and a drilling assembly. The support base is disposed on the worktable, and the drilling assembly is mounted on the worktable via the mounting bracket and is movable and adjustable along the height of the worktable. The clamping mechanism is disposed on the support base and includes a limiting component and a driving component. The limiting component is rotatably disposed within the support base, and the driving component is disposed on the support base for driving the limiting component to rotate.

[0007] In addition, the bearing manufacturing drilling device proposed above according to this utility model may also have the following additional technical features: Specifically, the limiting assembly includes a rotary cylinder, three guide grooves, a mounting plate, three sliding seats, three drive rods, a drive shaft, a support plate, and a retaining ring. The three guide grooves are all disposed on the mounting plate and are arranged in a ring around the axial direction of the mounting plate. The three sliding seats are slidably disposed inside the three guide grooves. One end of each of the three drive rods is pivotally connected to the drive shaft and is arranged in a ring around the axial direction of the drive shaft. The other end of each drive rod is pivotally connected to a sliding seat. The support plate is disposed on the sliding seat. The retaining ring is disposed on the mounting plate. The drive shaft is rotatably disposed within the mounting plate. The rotary cylinder is disposed on the mounting plate, and its cylinder shaft is connected to one end of the drive shaft.

[0008] Specifically, the drive assembly includes a gear ring, a gear, and a first drive member, wherein the gear is disposed on the output shaft of the first drive member, and the gear ring is meshed with the outer wall of the gear.

[0009] Specifically, the drilling assembly includes a linear module, a mounting base, and a second drive member, wherein the mounting base is disposed on the slider of the linear module, the second drive member is disposed on the mounting base, and a drill bit is mounted on its end.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention, by setting a limiting component and using a rotary cylinder to drive the drive shaft to rotate, can drive three support plates to move synchronously and provide stable constraint support for the bearing race from the inside, thereby enhancing the constraint force on the bearing race. During processing, it can prevent radial movement of the bearing race and ensure the stability of the bearing race during processing. Moreover, by supporting the bearing race from multiple directions, it can avoid slight deformation of thin-walled bearing races caused by concentrated clamping force, thus improving the processing quality of the bearing.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The following description, in conjunction with the accompanying drawings, describes a drilling device for bearing production according to an embodiment of the present invention.

[0016] like Figures 1-6 As shown in the figure, a drilling device for bearing production according to an embodiment of the present invention includes a worktable 1, a support base 2, a mounting frame 6, a clamping mechanism and a drilling assembly 5. The support base 2 is disposed on the worktable 1, and the drilling assembly 5 is disposed on the worktable 1 through the mounting frame 6 and can be moved and adjusted along the height direction of the worktable 1.

[0017] It should be noted that the support base 2 is fixed to the workbench 1 by bolts, and a circular through slot is provided on its top to facilitate the installation of the clamping mechanism. The drilling assembly 5 can achieve precise adjustment in the height direction in order to control the drilling accuracy.

[0018] The clamping mechanism is mounted on the support base 2. The clamping mechanism includes a limiting component 3 and a driving component 4. The limiting component 3 is rotatably mounted inside the support base 2, and the driving component 4 is mounted on the support base 2 to drive the limiting component 3 to rotate.

[0019] It should be noted that the limiting component 3 is used to stably limit the bearing ring. It constrains the bearing ring from the inside by using a three-jaw centering method, which enhances the constraint force on the bearing ring. As a result, it can prevent the bearing ring from radially moving during processing, thus ensuring the stability of the bearing ring during processing. Moreover, by supporting the bearing ring from multiple directions, it can prevent the slight deformation of thin-walled bearing rings caused by concentrated clamping force.

[0020] In one embodiment of this utility model, such as Figures 2-4 As shown, the limiting component 3 includes a rotary cylinder 31, three guide grooves 32, a mounting plate 33, three sliding seats 34, three drive rods 35, a drive shaft 36, a support plate 37, and a retaining ring 38. The three guide grooves 32 are all provided on the mounting plate 33 and are distributed in a ring around the axial direction of the mounting plate 33. The three sliding seats 34 are slidably disposed inside the three guide grooves 32.

[0021] It should be noted that the shape of the guide groove 32 is adapted to the shape of the sliding seat 34 to ensure that the sliding seat 34 will not wobble when sliding in the guide groove 32 and can move smoothly.

[0022] One end of each of the three drive rods 35 is pivotally connected to the drive shaft 36 and is arranged in a ring around the axis of the drive shaft 36. The other end of each drive rod 35 is pivotally connected to the sliding seat 34. The support plate 37 is disposed on the sliding seat 34. The retaining ring 38 is disposed on the mounting plate 33. The drive shaft 36 is rotatably disposed within the mounting plate 33. The rotary cylinder 31 is disposed on the mounting plate 33 and its cylinder shaft is connected to one end of the drive shaft 36.

[0023] It should be noted that the mounting plate 33 is rotatably connected to the inside of the support base 2. The rotary cylinder 31 is used to drive the three support plates 37 to move radially, which can tighten or loosen the bearing ring from the inside. The outer wall of the support plate 37 is bonded with rubber anti-slip strips, which can enhance the stability of the bearing ring when supporting it, and can also prevent the inside of the bearing ring from being scratched. The retaining ring 38 can play a role in axially limiting the bearing ring.

[0024] Specifically, when the rotary cylinder 31 is started, its cylinder shaft drives the drive shaft 36 to rotate. During the rotation of the drive shaft 36, the three drive rods 35 swing synchronously. Since the other end of the drive rod 35 is pivotally connected to the sliding seat 34, and the sliding seat 34 is slidably disposed in the guide groove 32, the swing of the drive rod 35 will drive the sliding seat 34 to move along the guide groove 32. The three sliding seats 34 move synchronously, thereby driving the three support plates 37 away from the axis of the mounting plate 33. The three support plates 37 will support the bearing ring from the inside of the bearing ring, thereby achieving stable clamping of the bearing ring.

[0025] In one embodiment of this utility model, such as Figure 5 As shown, the drive assembly 4 includes a gear ring 41, a gear 42 and a first drive member 43, wherein the gear 42 is disposed on the output shaft of the first drive member 43, and the gear ring 41 is meshed with the outer wall of the gear 42.

[0026] It should be noted that the first driving component 43 is a motor. The first driving component 43 is mounted on the support base 2, and the gear ring 41 is fixedly connected to the mounting plate 33 to drive the mounting plate 33 to rotate. Specifically, when the first driving component 43 is started, its output shaft drives the gear 42 to rotate. Since the gear ring 41 is meshed with the gear 42, the gear 42 drives the gear ring 41 to rotate. The gear ring 41 drives the mounting plate 33 to rotate. When the mounting plate 33 rotates, it drives the limiting component 3 to rotate as a whole. When the limiting component 3 rotates, it drives the bearing ring to perform drilling processing at different positions of the bearing ring.

[0027] In one embodiment of this utility model, such as Figure 6 As shown, the drilling assembly 5 includes a linear module 51, a mounting base 52, and a second drive member 53. The mounting base 52 is disposed on the slider of the linear module 51, and the second drive member 53 is disposed on the mounting base 52, with a drill bit 54 mounted at its end.

[0028] It should be noted that the linear module 51 is mounted on the support base 2, and the second drive component 53 is a motor. The drill bit 54 is rotated by the second drive component 53, which can realize the drilling operation of the bearing ring.

[0029] Understandably, the linear module 51 drives the mounting base 52 to move precisely along the height direction of the worktable 1 through its slider, thereby adjusting the height of the drill bit 54 and the drilling depth.

[0030] In actual use, the bearing race is first placed outside the three support plates 37 of the limiting component 3. The rotary cylinder 31 is started, and the cylinder shaft of the rotary cylinder 31 drives the drive shaft 36 to rotate. The drive shaft 36 drives the three sliding seats 34 to move along the guide groove 32 through the three drive rods 35. The three sliding seats 34 drive the three support plates 37 to move synchronously away from the axis of the mounting plate 33, so that the bearing race can be stably supported from the inside. The linear module 51 and the second drive component 53 are started. The second drive component 53 drives the drill bit 54 to rotate. The linear module 51 drives the mounting seat 52 and the second drive component 53 to move downward to drill holes in the bearing race. After the drilling is completed at this position, the first drive component 43 is started. With the cooperation of the gear 42 and the gear ring 41, the mounting plate 33 is driven to rotate. The mounting plate 33 drives the limiting component 3 and the bearing race to rotate so as to drill holes at different positions of the bearing race.

[0031] In summary, the bearing manufacturing drilling device of this utility model, by setting a limiting component and using a rotary cylinder to drive the drive shaft to rotate, can stably limit and support the bearing race from the inside, enhancing the constraint force on the bearing race. This prevents radial movement of the bearing race during processing, ensuring stability during the bearing race processing. Furthermore, supporting the bearing race from multiple directions avoids slight deformation of thin-walled bearing races due to concentrated clamping force, improving the bearing processing quality. Simultaneously, by setting a drive component, the limiting component and the bearing race can be rotated, facilitating drilling at different positions on the bearing race and improving drilling efficiency.
