Description

Technical Field

[0001] This utility model relates to the field of tapered roller bearing technology, specifically to a measuring tool for measuring the width of the inner ring flange of a tapered roller bearing. Background Technology

[0002] Tapered roller bearings are separable bearings, with tapered raceways on both the inner and outer rings. They are mainly used in automotive rear axle hubs, large machine tool spindles, and axle boxes.

[0003] When measuring the width of the inner ring flange of a tapered roller bearing, the traditional method is for the operator to hold a dial indicator and read the data by pressing the indicator tip against the lowest point of the flange, or to read the data by simultaneously pressing the steel ball at the bottom of the dial indicator clamp against the raceway and flange of the inner ring and then calculating the result. In order to improve the measurement quality, the operator needs to measure different parts of the inner ring flange. The instability of the hand-held method will affect the accuracy of the data, and repeated operation increases the workload of the operator. Utility Model Content

[0004] The purpose of this invention is to provide a measuring tool for measuring the width of the inner ring flange of a tapered roller bearing, which has the advantages of being easy and labor-saving to operate.

[0005] The technical solution of this utility model is as follows:

[0006] A measuring tool for measuring the width of the inner ring flange of a tapered roller bearing includes a worktable and a rotating ring rotatably connected to the worktable. The worktable contains a drive assembly for rotating the rotating ring. The top of the worktable has a fixing assembly for fixing the inner ring to be measured. The central axis of the inner ring coincides with the rotation axis of the rotating ring. A support platform is provided on the rotating ring. A radial slide along the top of the worktable is provided on the support platform. A lifting assembly is slidably connected to the slide. A fixing member is provided at one end of the lifting assembly near the slide for fixing the assembly in position on the slide. A clamping assembly is provided at the lifting end of the lifting assembly for clamping a dial indicator.

[0007] Preferably, the drive assembly includes a motor, a gear, and a gear ring. The rotating ring has a gear ring along its inner circumference. The worktable contains a motor, and the output end of the motor has a gear that meshes with the gear ring.

[0008] Preferably, the fixing component includes a threaded post and a pressure block. The top of the worktable is a cylinder whose central axis coincides with the rotation axis of the rotating ring. The threaded post is vertically provided at the center of the top of the worktable. The pressure block is formed by coaxially connecting the upper cylinder and the lower inverted frustum. The bottom end of the pressure block extends into the inner cavity of the inner ring. The inner edge of the top of the inner ring abuts against the conical surface of the frustum portion of the pressure block. The pressure block has a threaded through hole along the central axis that is threaded to the threaded post.

[0009] Preferably, a wear-resistant layer is provided on the conical surface of the frustum portion of the pressing block.

[0010] Preferably, the lifting assembly includes a slider, a vertical rod, a sliding sleeve, a horizontal rod, an insertion sleeve, and a support frame. The slider is slidably connected to the slide rail. The top of the slider is provided with a sliding sleeve in the vertical direction. The side of the sliding sleeve is provided with a horizontal rod pointing horizontally towards the central axis of the top of the worktable. The end of the horizontal rod is provided with an insertion sleeve for inserting the dial portion of the dial indicator. The upper end of the insertion sleeve is provided with a support frame for supporting the dial portion of the dial indicator. The slider is provided with a fixing screw A that can be screwed to abut against the slide rail. The sliding sleeve is provided with a fixing screw B that can be screwed to abut against the vertical rod. The support frame is provided with a fixing screw C that can be screwed to abut against the dial of the dial indicator.

[0011] The beneficial technical effects of this utility model are as follows:

[0012] The drive component rotates the rotating ring, causing the dial indicator, which is indirectly connected to the rotating ring, to rotate around the inner ring. This allows the steel ball at the bottom of the clamp on the dial indicator tip to move slowly along the inner ring's flange. During this process, the operator can focus on collecting the deflection data displayed on the dial indicator. Compared to the traditional method of manually measuring the width of the inner ring flange with a handheld dial indicator, the measurement method of this invention is more labor-saving and allows for more stable movement of the dial indicator.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Example:

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a measuring tool for measuring the width of the inner ring flange of a tapered roller bearing, including a worktable 1 and a rotating ring 2. The rotating ring 2 is rotatably connected to the worktable 1. The worktable 1 is provided with a driving assembly 3 for driving the rotating ring 2 to rotate. The top of the worktable 1 is provided with a fixing assembly 4 for fixing the inner ring 5 to be measured. The central axis of the inner ring 5 coincides with the rotation axis of the rotating ring 2. The rotating ring 2 is provided with a support platform 6. The support platform 6 is provided with a slide rail 7 along the radial direction of the top of the worktable 1. A lifting assembly 8 is slidably connected to the slide rail 7. The end of the lifting assembly 8 near the slide rail 7 is provided with a fixing member 9 for fixing the position on the slide rail 7. The lifting end of the lifting assembly 8 is provided with a clamping assembly 10 for clamping a dial indicator.

[0020] The drive component 3 drives the rotating ring 2 to rotate, which in turn drives the dial indicator indirectly connected to the rotating ring 2 to rotate around the inner ring 5. This causes the steel ball at the bottom of the clamp on the tip of the dial indicator to move slowly along the edge of the inner ring 5. During this process, the operator can concentrate on collecting the deflection data displayed on the dial indicator. Compared with the traditional method of manually measuring the width of the edge of the inner ring 5 with a handheld dial indicator, the measurement method of this invention is more labor-saving and can move the dial indicator more stably.

[0021] Furthermore, the drive assembly 3 includes a motor 11, a gear 12 and a gear ring 13. The rotating ring 2 is provided with a gear ring 13 along its inner circumference. The worktable 1 is provided with a motor 11. The output end of the motor 11 is provided with a gear 12, which meshes with the gear ring 13.

[0022] The motor 11 drives the gear 12 to rotate, and the rotating gear 12 drives the meshing gear ring 13 to rotate, thereby driving the rotating ring 2 connected to the gear ring 13 to rotate.

[0023] Furthermore, the fixing component 4 includes a threaded post 14 and a pressure block 15. The top of the worktable 1 is a cylinder whose central axis coincides with the rotation axis of the rotating ring 2. The threaded post 14 is vertically provided at the center of the top of the worktable 1. The pressure block 15 is formed by the upper cylinder and the lower inverted frustum coaxially connected. The bottom end of the pressure block 15 extends into the inner cavity of the inner ring 5. The inner edge of the top of the inner ring 5 abuts against the conical surface of the frustum portion of the pressure block 15. The pressure block 15 is provided with a threaded through hole 16 along the central axis that is threadedly connected to the threaded post 14.

[0024] During the process of pressing the inner ring 5 down by the pressure block 15, the inner ring 5 can be pushed to a position coaxial with the top of the worktable 1 by the frustum part of the pressure block 15, which facilitates subsequent measurement work. When installing the inner ring 5, first remove the pressure block 15 from the threaded post 14, and then place the inner ring 5 on the top of the worktable 1 with the threaded post 14 passing through the inner cavity of the inner ring 5. Then screw the pressure block 15 onto the threaded post 14 and continue to screw it down. The inner edge of the top of the inner ring 5 that first contacts the pressure block 15 is pushed outward by the descending pressure block 15. When the inner edge of the top of the inner ring 5 is in contact with the pressure block 15, the inner ring 5 has moved to a position coaxial with the top of the worktable 1 and the pressure block 15 has pressed down on the inner ring 5.

[0025] Furthermore, a wear-resistant layer 17 is provided on the conical surface of the frustum portion of the pressure block 15.

[0026] The wear-resistant layer 17 reduces surface wear on the pressure block 15.

[0027] Furthermore, the lifting assembly 8 includes a slider 18, a vertical rod, a sliding sleeve 20, a horizontal rod 21, an insertion sleeve 22, and a support frame 23. The slider 18 is slidably connected to the slide rail 7. The top of the slider 18 is provided with a sliding sleeve 20 in the vertical direction. The side of the sliding sleeve 20 is provided with a horizontal rod 21 pointing horizontally to the central axis of the top of the worktable 1. The end of the horizontal rod 21 is provided with an insertion sleeve 22 for inserting the dial part of the dial indicator. The upper end of the insertion sleeve 22 is provided with a support frame 23 for supporting the dial part of the dial indicator. The slider 18 is provided with a fixing screw A24 that can be screwed to abut against the slide rail 7. The sliding sleeve 20 is provided with a fixing screw B25 that can be screwed to abut against the vertical rod. The support frame 23 is provided with a fixing screw C26 that can be screwed to abut against the dial of the dial indicator.

[0028] By using slider 18 and slide rail 7 together, the horizontal position of the steel ball can be adjusted. By using sleeve 20 and vertical rod together, the vertical height of the high ball can be adjusted. This allows the steel ball to be moved to the appropriate position to meet the measurement requirements of different inner rings 5. When installing the dial indicator, first insert the dial indicator rod into the insertion sleeve 22 and place the dial indicator dial on the support frame 23. Then, attach the appropriate clamp and the matching steel ball to the dial indicator tip. After slider 18 is moved to the appropriate position, tighten fixing screw A24 until it is tightly against slide rail 7 to fix the position of slider 18 on slide rail 7. After sleeve 20 is moved to the appropriate position, tighten fixing screw B25 until it is tightly against vertical rod to fix the position of sleeve 20 on vertical rod. After the dial indicator is placed on support frame 23, tighten fixing screw C26 until it is tightly against the dial indicator to stably fix the dial indicator on support frame 23.

[0029] Specifically, the inner cavity of the insertion sleeve 22 is vertical and the top of the inner cavity is connected to the bottom of the support frame 23. The support frame 23 is shaped like a lower semicircle, and there are two fixing screws C26, each of which is rotatably connected to the left and right ends of the support frame 23.

[0030] Working principle and usage process of this utility model:

[0031] Based on the specifications of the inner ring 5 to be measured, the staff selects appropriate dial indicator clamps, steel balls, and height blocks. First, the dial indicator is mounted on the support frame 23 and the insertion sleeve 22 and fixed. Then, the dial indicator clamp is installed on the tip of the dial indicator, and the steel ball is installed on the clamp. The sliding sleeve 20 is moved to the appropriate position and fixed. The height block helps the dial indicator to zero. Then, the inner ring 5 is placed on the top of the workbench 1 and fixed. Next, the slider 18 is moved to the appropriate position so that the steel ball abuts against the top of the inner ring 5 retaining edge and the inner ring 5 raceway. After fixing the position of the slider 18, the motor 11 is started. The motor 11 drives the rotating ring 2 to rotate, thereby allowing the steel ball indirectly connected to the rotating ring 2 to move along the inner ring 5 retaining edge. During this process, the staff collects the deflection data displayed by the dial indicator.

[0032] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
