Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and more specifically, to a drilling device for processing ceramic ball bearings. Background Technology

[0002] In the development and application of engineering ceramic products, ceramic ball bearings are a typical example of the widespread application of engineering ceramics in the industrial field. Among high-speed precision bearings, hybrid ceramic ball bearings are the most widely used, that is, the rolling elements use hot-pressed Si3N4 ceramic balls, while the bearing ring is still a steel ring. During the production process of ceramic ball bearings, the inner ring of the bearing needs to be drilled to facilitate subsequent assembly. However, the existing technology has the following shortcomings in use:

[0003] After drilling the bearing inner ring, the clamping mechanism is released. Often, the operator has to manually remove the bearing inner ring. Repeating this operation multiple times undoubtedly increases the labor intensity of the operator in actual work. It also makes it impossible to automatically collect the bearing inner ring, which is not conducive to actual production and processing.

[0004] Therefore, there is an urgent need for a drilling device for machining ceramic ball bearings to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that after drilling the inner ring of a bearing, the clamping mechanism is released, and the operator often has to manually remove the inner ring of the bearing. After repeated operations, this undoubtedly increases the labor intensity of the operator in actual work, and it is impossible to automatically collect the inner ring of the bearing, which is not conducive to actual production and processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drilling device for machining ceramic ball bearings, to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A drilling device for machining ceramic ball bearings includes a worktable. A frustum and two symmetrically arranged guide rails are fixedly installed on the top of the worktable. Slide seats are slidably connected to both guide rails. A through groove and a discharge port are provided on the worktable. A first electric push rod is provided below the frustum. A connecting plate is fixedly connected to the push rod end of the first electric push rod. Two symmetrically distributed transmission plates are hinged to the connecting plate. The end of the transmission plate away from the connecting plate is hinged to the slide seat. An L-shaped plate is fixedly installed on the top of the slide seat. A clamping plate is fixedly installed on the end face of the L-shaped plate near the frustum. A connecting rod is fixedly connected to the center of the top of the connecting plate. An arc-shaped push plate is fixedly installed on the end of the connecting rod away from the connecting plate. A material collection frame is provided on the inner bottom surface of the worktable, located directly below the discharge port.

[0010] As a preferred technical solution of this application, a fixed frame located directly behind the frustum is fixedly connected to the top of the workbench. A second electric push rod is fixedly installed on the top surface of the fixed frame. A mounting plate is fixedly connected to the push rod end of the second electric push rod. A drilling mechanism is provided at the bottom of the mounting plate.

[0011] As a preferred technical solution of this application, the drilling mechanism includes a drive motor fixedly installed on the bottom of the mounting plate, and a drill bit is fixedly installed on the output end of the drive motor.

[0012] As a preferred technical solution of this application, a base is fixedly connected to the inner top wall of the workbench, and the first electric push rod is fixedly installed on the front of the base.

[0013] As a preferred technical solution of this application, the discharge port is located between the placement frustum and the fixed frame, and the length and width of the discharge port are both greater than the diameter of the placement frustum.

[0014] As a preferred technical solution of this application, the clamping plate is arc-shaped, and the two clamping plates are symmetrically distributed about the central axis of the placed frustum.

[0015] As a preferred technical solution of this application, the connecting plate is slidably connected in the through groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. After drilling the bearing inner ring, the first electric push rod drives the connecting plate to move closer to the base. Through the cooperation of the transmission plate, guide rail, slide block and L-shaped plate, the two clamping plates move away from each other. At the same time, the connecting rod and arc-shaped push plate move synchronously with the connecting plate. The arc-shaped push plate pushes the bearing inner ring placed on the top of the truncated cone, so that it falls into the collection frame through the discharge port. This realizes the automatic collection of the bearing inner ring, which saves time and effort, improves work efficiency, reduces the labor intensity of operators, and is beneficial to actual production and processing.

[0019] 2. By cooperating with the second electric push rod, mounting plate and drilling mechanism, the outer ring of the bearing can be drilled. Attached Figure Description

[0028] Example:

[0029] like Figure 1-4 As shown, this embodiment proposes a drilling device for machining ceramic ball bearings, including a worktable 1. A frustum 2 and two symmetrically arranged guide rails 3 are fixedly installed on the top of the worktable 1. The bearing inner ring to be machined is placed on the top of the frustum 2. Slide seats 4 are slidably connected to both guide rails 3. A through groove 5 and a discharge port 6 are provided on the worktable 1. A first electric push rod 7 is provided below the frustum 2. A connecting plate 8 is fixedly connected to the push rod end of the first electric push rod 7. When the first electric push rod 7 is activated, the connecting plate 8 is moved away from the frustum 2. Two symmetrically distributed transmission plates 9 are hinged to the connecting plate 8. The end of the transmission plate 9 away from the connecting plate 8 is connected to... The slide blocks 4 are hinged together and slide on the two guide rails 3 respectively through two transmission plates 9. The two slide blocks 4 are close to each other. An L-shaped plate 10 is fixedly installed on the top of the slide block 4. A clamping plate 11 is fixedly installed on the end face of the L-shaped plate 10 near the side where the truncated cone 2 is placed. The two clamping plates 11 are close to each other through the two L-shaped plates 10. The inner ring of the bearing is clamped and positioned by the two clamping plates 11. A connecting rod 12 is fixedly connected to the center of the top of the connecting plate 8. An arc-shaped push plate 13 is fixedly installed on the end of the connecting rod 12 away from the connecting plate 8. A material collection frame 14 is set on the inner bottom surface of the workbench 1, located directly below the discharge port 6. The connecting rod 12 and the arc-shaped push plate 13 move synchronously with the connecting plate 8.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a fixed frame 15 is fixedly connected to the top of the workbench 1, located directly behind the placed truncated cone 2. A second electric push rod 16 is fixedly installed on the inner top surface of the fixed frame 15. A mounting plate 17 is fixedly connected to the push rod end of the second electric push rod 16. A drilling mechanism is provided at the bottom of the mounting plate 17. When the second electric push rod 16 is activated, the mounting plate 17 and the drilling mechanism are moved down through the second electric push rod 16, which facilitates the subsequent drilling of the bearing inner ring.

[0031] like Figure 2 and Figure 3 As shown, the drilling mechanism includes a drive motor 18 fixedly installed at the bottom of the mounting plate 17. A drill bit 19 is fixedly installed at the output end of the drive motor 18. When the drive motor 18 is started, the drill bit 19 is driven to rotate at high speed. When the second electric push rod 16 moves the mounting plate 17 down, the drive motor 18 and the rotating drill bit 19 move down accordingly, thereby realizing the drilling of the inner ring of the bearing.

[0032] like Figure 2 and Figure 3 As shown, a base 20 is fixedly connected to the inner top wall of the workbench 1, and the first electric push rod 7 is fixedly installed on the front of the base 20.

[0033] like Figure 1 and Figure 2 As shown, the discharge port 6 is located between the placement truncated cone 2 and the fixed frame 15. The length and width of the discharge port 6 are both greater than the diameter of the placement truncated cone 2. When the arc-shaped push plate 13 pushes the bearing inner ring towards the fixed frame 15, the bearing inner ring can fall into the collection frame 14 through the discharge port 6.

[0034] like Figure 1 and Figure 2 As shown, the clamping plate 11 is arc-shaped, and the two clamping plates 11 are symmetrically distributed about the central axis of the placed frustum 2. The two arc-shaped clamping plates 11 can facilitate the fixing of the bearing inner ring and ensure the fixing effect of the bearing inner ring.

[0035] like Figure 2 and Figure 3 As shown, the connecting plate 8 is slidably connected to the through groove 5.

[0036] Specifically, in use, the drilling device for processing ceramic ball bearings is as follows: the first electric push rod 7, the second electric push rod 16, and the drive motor 18 are all electrically connected to an external control power supply. The operator places the inner ring of the bearing to be processed on the top of the placement platform 2, and then starts the first electric push rod 7. The first electric push rod 7 drives the connecting plate 8 to move away from the placement platform 2. Through the two transmission plates 9, the two slide blocks 4 slide on the two guide rails 3 respectively, and the two slide blocks 4 move closer to each other. Through the two L-shaped plates 10, the two clamping plates 11 move closer to each other, and the two arc-shaped clamping plates 11 clamp and position the inner ring of the bearing. Then, the second electric push rod 16 and the drive motor 18 are started. The drive motor 18 drives the drill bit 19 to rotate at high speed, and the second electric push rod 16 drives the mounting plate 17, the drive motor 18, the connecting plate 8, the connecting plate 8, and the drive motor 18 to rotate at high speed. The drive motor 18 and drill bit 19 move downwards to drill holes in the inner ring of the bearing. After drilling, the second electric push rod 16 drives the drive motor 18 to move upwards and reset. Then, the first electric push rod 7 drives the connecting plate 8 to move closer to the base 20. The two transmission plates 9 cooperate with the two slides 4 to move the two L-shaped plates 10 and the two clamping plates 11 away from each other, releasing the fixation of the inner ring of the bearing. At the same time, the connecting rod 12 and the arc-shaped push plate 13 move synchronously with the connecting plate 8. The arc-shaped push plate 13, which moves closer to the base 20, pushes the inner ring of the bearing placed on the top of the frustum 2 down, so that the inner ring of the bearing falls into the collection frame 14 through the discharge port 6. This realizes the automatic collection of the inner ring of the bearing, which saves time and effort, improves work efficiency, reduces the labor intensity of operators, and is beneficial to actual production and processing.
