Description

Technical Field

[0001] This invention belongs to the field of workpiece measurement, and particularly relates to a bearing protrusion measuring device and method. Background Technology

[0002] In existing technologies, the measurement of bearing protrusion typically relies on manual loading and unloading of load blocks, which is inefficient and labor-intensive. The lack of a temporary storage and flipping mechanism hinders continuous operation. Furthermore, manual positioning easily introduces errors, reducing measurement accuracy and consistency. In addition, traditional devices have simple structures, limited functions, and poor adaptability.

[0003] Meanwhile, the measurement of the protrusion of large angular contact ball bearings of 7020 and above is a challenge. Due to the large size, high cost, and low production volume of this type of bearing, mainstream automated measurement equipment generally cannot cover it. Currently, it mainly relies on manual operation, which leads to poor measurement consistency and the inability to operate continuously, thus restricting the quality and reliability of the product. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a bearing protrusion measuring device and method that can solve the aforementioned technical issues.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions: A bearing protrusion measuring device includes a worktable, a protrusion measuring instrument disposed on the worktable, and a bearing carrier located below the protrusion measuring instrument. The bearing protrusion measuring device further includes: A block storage mechanism is provided with a block bearing groove, and the block storage mechanism moves back and forth alternately with respect to the worktable in the first axial direction between a block unloading position and a block flipping position; the bearing carrier is located below the block unloading position; A load carrier block having a shaft placed in a load carrier groove; one end of the load carrier block has a conformal bearing inner ring portion, and the other end of the load carrier block has a conformal bearing outer ring portion; A block unloading mechanism is provided, wherein the block unloading mechanism is located at the block unloading position, and the block unloading mechanism drives the shaft to disengage from or enter the block bearing groove.

[0006] Furthermore, the block storage mechanism includes two sliding blocks that slide synchronously relative to the worktable surface. Each sliding block is provided with a block bearing groove. A movable limiting seat is fixed on the worktable surface, and a movable limiting bracket is detachably connected to the movable limiting seat. The movable limiting bracket is rotatably connected to the sliding block.

[0007] Furthermore, there are two movable distance limiting seats distributed on a second axis perpendicular to the first axis. Each movable distance limiting seat is provided with a slot, and the movable distance limiting bracket is U-shaped and can be detachably engaged with the slot.

[0008] Furthermore, an overhead support is provided on the workbench, the sliding block is connected to the overhead support via a sliding member, and the movable distance limiting seat is fixed on the overhead support.

[0009] Furthermore, there are two sliding members, and each of the sliding members is slidably connected to a sliding block, with the end of the sliding member near the unloading position of the carrier block being suspended in the air.

[0010] Furthermore, the block unloading mechanism includes a block unloading bracket that is linearly and dynamically connected to the worktable surface. The block unloading bracket has two bearing shoulders that can contact the inner ring of the profile bearing or the outer ring of the profile bearing. The block unloading bracket is connected to the lifting drive assembly.

[0011] Furthermore, the lifting drive assembly includes either a manual lifting drive assembly or an automated lifting drive assembly.

[0012] Furthermore, the lifting drive assembly includes a gear support fixed to the worktable and a rotating shaft that rotates relative to the gear support. An eccentric wheel is provided on the rotating shaft that intermittently contacts the bottom of the block unloading bracket. A control arm is provided on the rotating shaft that is circumferentially fixed to the rotating shaft and axially movable relative to the rotating shaft. At least one of the gear supports is provided with a plurality of gears.

[0013] As one application, this application also provides a method for measuring bearing protrusion, the method comprising the following steps: S1. Under external force, the load storage mechanism drives the load block to the load block flipping position, and places the bearing to be measured on the bearing carrier. S2. Under external force, the load block temporary storage mechanism described in S1 drives the load block to the load block unloading position; S3, the load unloading mechanism causes the shaft of the load block in S2 to disengage from the load block bearing groove of the load block temporary storage mechanism, and the inner ring of the conforming bearing of the load block after disengagement presses against the inner ring of the bearing or the outer ring of the conforming bearing of the load block after disengagement presses against the outer ring of the bearing. S4. The protrusion measuring instrument tests the distance of the load block from the top setting surface of the bearing, thereby completing the height measurement of the inner ring or outer ring of the conformal bearing.

[0014] Furthermore, in S3 above, the load block temporary storage mechanism alternates between the load block unloading position and the load block flipping position, and when in the load block flipping position, the load block rotates and flips relative to the load block temporary storage mechanism under the drive of rotational force, so that the positions of the inner ring of the conformal bearing and the outer ring of the conformal bearing are interchanged; and a vacuum breaking component is placed between the bearing and the load block.

[0015] Compared with existing technologies, the advantages of this application are: the device integrates the previously scattered actions that relied entirely on the worker's touch and experience into a structured process completed by the coordinated mechanism. The worker only needs to operate the mechanism step by step (such as moving the temporary storage mechanism to the designated position and controlling the unloading mechanism) to complete the precise picking, placing, flipping and positioning of the carrier block, which significantly reduces positioning errors and improves testing efficiency; at the same time, it solves the problem of measuring the protrusion of existing large angular contact ball bearings.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0022] Example 1

[0023] like Figures 1-3As shown, the bearing protrusion measuring device includes a worktable 1 serving as a base, a protrusion measuring instrument 2 mounted on the worktable 1, and a bearing carrier 3 located below the protrusion measuring instrument 2. The protrusion measuring instrument 2 is used to detect the end face protrusion of the bearing to be tested. It obtains the height difference data of the bearing relative to the set reference surface by forming a stable measuring contact with the bearing end face or reference part, and presents the measurement results in the form of an indication or output to determine whether the bearing protrusion meets the process tolerance requirements. The bearing carrier 3 located below the protrusion measuring instrument 2 is used to support and position the bearing to be tested. It achieves radial and axial positioning of the bearing through a limiting structure that cooperates with the outer ring, inner ring, or end face of the bearing, so that the bearing maintains a stable posture at the measurement position and ensures a unified measurement reference.

[0024] like Figure 1 and Figure 4 As shown, the bearing protrusion measuring device also includes: a block storage mechanism 4, which is provided with a block bearing groove 411, and the block storage mechanism 4 moves back and forth alternately with respect to the worktable 1 in the first axis X direction at the block unloading position and the block flipping position; the bearing carrier 3 is located below the block unloading position. By setting up a temporary storage mechanism 4 for the load block, the load block 5 can be received and temporarily stored in an orderly manner. By using its reciprocating alternating movement between the load block unloading position and the load block flipping position, the load block can be transferred and its posture flipped between different work positions, thereby reducing manual handling and flipping operations, reducing the risk of misoperation and improving stability. At the same time, the load block bearing groove 411 provides limit and support for the load block 5, so that the load block 5 maintains a consistent position during movement, which is beneficial to the repeatability accuracy of subsequent unloading and measurement operations. Furthermore, since the bearing carrier 3 is arranged below the load block unloading position, the bearing or bearing-related bearing objects can be quickly connected under the same reference system after the load block 5 is unloaded, shortening the alignment time and reducing the accumulation of positioning errors.

[0025] The load carrier 5 has a shaft 53 placed in the carrier bearing groove 411; one end of the load carrier 5 has a shaped bearing inner ring portion 51, and the other end has a shaped bearing outer ring portion 52. Through the cooperation between the shaft 53 and the carrier bearing groove 411, the load carrier 5 can maintain reliable positioning and stable support during temporary storage and transfer, avoiding damage or positioning deviation caused by shaking; furthermore, the shaped bearing inner ring portion 51 and the shaped bearing outer ring portion 52 are used to simulate the assembly force and contact shape of the bearing inner and outer rings, respectively, so that the bearing under test is closer to the actual assembly state during measurement, thereby improving the authenticity and consistency of the protrusion detection results and reducing data deviation caused by different clamping methods; the double-end shaped structure facilitates the rapid switching detection of the bearing front and back or different end faces, and can further improve the reversing efficiency when combined with the carrier flip position.

[0026] In addition, the block storage mechanism 4 includes two sliding blocks 41 that slide synchronously relative to the worktable 1. Each sliding block 41 is provided with a block bearing groove 411. A movable limiting seat 42 is fixed on the worktable 1, and a movable limiting bracket 43 is detachably connected to the movable limiting seat 42. The movable limiting bracket 43 is rotatably connected to the sliding block 41. The sliding block 41 is used to support and drive the load block 5 to move in the first axis X direction, so that the load block 5 can be synchronously transferred between the load block unloading position and the load block flipping position. The load block 5 is set alone, and the two sliding blocks 41 are used to provide synchronous support and guidance during the transfer of the same load block 5. Each sliding block 41 is provided with a load block bearing groove 411, so that the load block 5 forms a stable bearing state with double-sided limit / double-point support when moving. This is conducive to maintaining the consistent axial posture of the shaft 53, ensuring that the load block 5 is reliably centered when entering the working area of ​​the load unloading mechanism 6, thereby improving the smoothness and consistency of the shaft 53 when leaving or entering the load block bearing groove 411, and further ensuring the stability of the measurement reference.

[0027] The movable distance limiting seat 42 is fixed on the worktable 1 to limit the travel of the two sliding blocks 41 and provide fixation to prevent misalignment or affect the test. The movable distance limiting bracket 43 is detachably connected to the movable distance limiting seat 42, and the movable distance limiting seat 42 can be finely adjusted in the first axis X direction, which facilitates quick setting of travel limits when changing different specifications of load blocks 5 or adjusting the station distance, reducing machine setup time and improving the versatility of the device. The movable distance limiting bracket 43 is rotatably connected to the sliding blocks 41 respectively, so that the distance and guide are adjusted during the reciprocating process of the sliding blocks 41. Furthermore, there are two movable distance limiting seats 42 and they are distributed on the second axis Y perpendicular to the first axis X. Each movable distance limiting seat 42 is provided with a slot 421, and the movable distance limiting bracket 43 is U-shaped and detachably engaged with the slot 421. By distributing two movable limiting seats 42 along the second axis Y, a symmetrical limiting reference can be formed for the sliding block 41 in the lateral direction, making it less prone to swaying and twisting when the load storage mechanism 4 reciprocates in the first axis X direction, thereby improving the posture stability and positioning consistency of the load block 5 during the transfer process; at the same time, the slot 421 and the U-shaped movable limiting bracket 43 adopt a detachable snap-fit ​​connection, which can quickly complete the position adjustment of the limiting component without disassembling the fasteners, making it convenient to set the stroke according to different specifications of load blocks 5 or different workstation spacing requirements, reducing the machine adjustment time and improving maintenance convenience, and the snap-fit ​​structure is not easy to loosen after being subjected to force, which helps to ensure the reliability of the limiting.

[0028] like Figures 1-6As shown, an overhead support 44 is provided on the worktable 1. The sliding block 41 is connected to the overhead support 44 via a sliding member 45, and a movable limiting seat 42 is fixed to the overhead support 44. Fixing the movable limiting seat 42 to the overhead support 44 ensures the stroke accuracy and repeatability of the reciprocating movement of the sliding block 41, making the switching of the load block 5 between the unloading position and the flipping position more reliable. Furthermore, there are two sliding members 45, and a sliding block 41 is slidably connected to each sliding member 45. The end of the sliding member 45 near the unloading position is suspended. By guiding the two sliding blocks 41 with two sliding members 45 respectively, a double-guided support structure can be formed, which makes the sliding motion more uniform and stronger in resisting lateral forces, thereby reducing sliding resistance and the probability of jamming, and ensuring that the load block 5 is transferred smoothly and stably. At the same time, the end of the sliding member 45 near the unloading position of the load block is suspended, which makes it easier to reserve operating space for the bearing carrier 3 and the load unloading mechanism 6 at the unloading position, reducing structural obstruction and interference.

[0029] In addition, such as Figures 1-3 As shown, the bearing protrusion measuring device also includes: a load unloading mechanism 6, which is located at the load unloading position, and a drive shaft 53 of the load unloading mechanism 6 that disengages from or enters the load bearing groove 411. By setting the load unloading mechanism 6, the load block 5 can be unloaded and reloaded at the load unloading position, ensuring a smooth loading and unloading process and reducing jamming; at the same time, the loading and unloading action can be coordinated with the reciprocating motion of the load temporary storage mechanism 4 to achieve continuous flipping and reduce downtime.

[0030] Furthermore, the block unloading mechanism 6 includes a block unloading bracket 61 linearly and dynamically connected to the worktable 1. The block unloading bracket 61 has two bearing shoulders 611 that can contact the inner ring 51 or the outer ring 52 of the contour bearing. The block unloading bracket 61 is connected to the lifting drive assembly 62. By setting the block unloading bracket 61 to move linearly relative to the worktable 1, it can achieve controlled vertical support and drop of the load block 5 at the unloading position. The loading and unloading path is clear and the force direction is consistent, thereby reducing the risk of scraping, deflection and jamming caused by lateral force. In addition, the two bearing shoulders form a double-point support structure, which can stably contact the inner ring 51 or the outer ring 52 of the contour bearing respectively, so that the load block 5 maintains a balanced posture during unloading and reloading, avoiding overturning or stress concentration caused by single-point support, further improving the stability and positioning consistency of loading and unloading, and also helping to reduce local wear on the contouring parts and extend the service life of the block.

[0031] The lifting drive assembly 62 includes either a manual lifting drive assembly or an automated lifting drive assembly. Manual lifting can be used to reduce equipment costs and facilitate maintenance when a complex control system is not required. Automated lifting can be used to achieve constant lifting speed and stable output force when it is necessary to improve cycle time and consistency. This allows the block unloading mechanism 6 to be adapted to different production line configurations and usage scenarios. In this embodiment, a manual lifting drive assembly is used as an example.

[0032] The lifting drive assembly 62 includes a gear support 621 fixed on the worktable 1, which can classify and limit the working height or stroke position of the block unloading bracket 61, so that the loading and unloading action has a clear endpoint, facilitating quick switching for different bearing specifications or different loading and unloading stages; and a rotating shaft 622 that rotates relative to the gear support 621. An eccentric wheel 623 is provided on the rotating shaft 622 that intermittently contacts the bottom of the block unloading bracket 61. This purpose is to convert rotational motion into smooth lifting motion. A control arm 63 is provided on the rotating shaft 622 that is circumferentially fixed to the rotating shaft 622 and axially movable relative to the rotating shaft 622. At least one gear support 621 has several gear positions 6211. In this embodiment, for example... Figure 2 As shown, the rotating shaft 622 and the control arm 63 can move axially relative to each other, so that the control arm 63 can enter different gear supports 621 to realize gear adjustment for different working sections.

[0033] The worktable 1 is provided with a carrier platform 8 and a Y-shaped positioning block 9 on the carrier platform 8. The Y-shaped positioning block 9 can quickly guide and limit the positioning of the bearing carrier 3, so that it automatically fits the positioning surface during placement, reducing manual alignment time and reducing sway error.

[0034] Example 2

[0035] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference lies in that, for the bearing protrusion measuring device of Embodiment 1, this embodiment describes the measurement method of the bearing protrusion measuring device.

[0036] S1. Under external force, the load storage mechanism 4 drives the load block 5 to the load flip position, and the bearing 7 to be measured is placed on the bearing carrier 3. In this embodiment, the operator first pushes the load storage mechanism 4 to move along the first axis X to the load flip position, and flips the load block 5 to the predetermined posture according to the working condition to be measured (so that the inner ring part 51 of the conformal bearing or the outer ring part 52 of the conformal bearing is on the lower side to be pressed), and then places the bearing 7 on the bearing carrier 3 and completes the positioning.

[0037] S2. Under external force, the load block temporary storage mechanism 4 drives the load block 5 to the load block unloading position; the load block 5 moves with the load block temporary storage mechanism 4 to the position aligned with the load block unloading mechanism 6, and the bearing carrier 3 is located below the load block unloading position to ensure that the load block 5 can be in a centered and pressed state with the bearing 7 after unloading.

[0038] S3, the load unloading mechanism 6 causes the shaft 53 of the load block 5 in S2 to disengage from the load bearing groove 411 of the load temporary storage mechanism 4. After disengagement, the inner ring 51 of the conformal bearing of the load block 5 presses against the inner ring of the bearing 7, or the outer ring 52 of the conformal bearing of the load block 5 presses against the outer ring of the bearing 7. In this embodiment, the load temporary storage mechanism 4 moves back and forth between the load unloading position and the load flipping position under the action of external force. When the load temporary storage mechanism 4 is in the load flipping position, the load block 5 rotates and flips relative to the load temporary storage mechanism 4 under the drive of rotational force, so that the positions of the inner ring 51 and the outer ring 52 of the conformal bearing are interchanged, thereby realizing the switching between the inner ring measurement condition and the outer ring measurement condition. Subsequently, at the unloading position of the load block, the operator drives the lifting drive assembly to raise the load block unloading bracket 61 vertically, so that the load block 5 is supported by the bearing shoulder and the shaft 53 is disengaged from the load block bearing groove 411, and the disengaged load block 5 is pressed onto the bearing 7: when the inner ring pressing is selected, the inner ring portion 51 of the profile bearing is pressed onto the inner ring of the bearing 7; when the outer ring pressing is selected, the outer ring portion 52 of the profile bearing is pressed onto the outer ring of the bearing 7.

[0039] S4. The protrusion measuring instrument 2 measures the distance between the load block 5 and the top set surface of the bearing 7, thus completing the height measurement of the inner ring 51 or outer ring 52 of the conformal bearing. After the load block 5 is pressed and stabilized, the measurement value of the protrusion measuring instrument 2 is read, the height of the top set surface of the load block 5 is detected and the data is recorded to obtain the height measurement result corresponding to the inner ring 51 or outer ring 52 of the conformal bearing, which is then used to determine whether the protrusion of the bearing 7 meets the preset requirements.

[0040] Furthermore, a vacuum-breaking component is placed between the bearing 7 and the load block 5 to break any negative pressure adsorption that may form on the contact surface during pressing or separation, facilitating the rapid and smooth separation of the load block 5 and the bearing 7. This component maintains extremely fine air channels through its surface structure when the two are tightly pressed together under pressure, effectively preventing the formation of localized vacuum adsorption between the contact surfaces. When it is necessary to separate the load block 5 and the bearing 7, external air can enter the inner space through the channels, balancing the internal and external pressure difference, allowing the two to separate easily and smoothly, avoiding the impact caused by adhesion due to negative pressure or sudden separation.

[0041] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
