Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing detection, in particular to a multiple detection device for deep groove ball bearings. BACKGROUND

[0002] When the deep groove ball bearings are shipped, their performance needs to be sampled and inspected, and in the performance inspection items, the temperature rise, noise and vibration detection are included, which requires a multiple detection device for deep groove ball bearings to implement one-time multiple detection of the above three detection items.

[0003] Most of the existing detection devices lack a stripping and dismounting mechanism capable of stripping and dismounting the bearings, which requires the use of external stripping tools for dismounting the bearings. The numerous components on the detection device and the cramped space formed by these components will interfere with the stripping and dismounting action of the bearings by hand-holding external stripping tools, thereby causing the stripping and dismounting operation of the bearings to be more troublesome and inconvenient. Although some detection devices in the prior art are provided with a stripping and dismounting mechanism, the stripping and dismounting mechanism still needs to be manually operated and cannot be driven by the original and necessary power unit of the device, which is still more troublesome and inconvenient to use. SUMMARY

[0006] Further, the two shaft rings are in sliding fit with the main shaft, and two vertical transmission plates and two horizontal sliding plates are symmetrically welded on the outer periphery of one shaft ring in cross-shaped symmetry; The middle portions of the two vertical guide rods are symmetrically welded with two longitudinal guide shafts, the two horizontal sliding plates are in sliding fit with the two longitudinal guide shafts, and the spring set for pushing the stripping assembly is sleeved on the longitudinal guide shaft and compressed and clamped between the horizontal sliding plate and the vertical guide rod.

[0007] Further, a T-shaped sliding groove is formed on the vertical support rod of the cross-shaped transmission frame, a I-shaped sliding block is slidingly installed in the T-shaped sliding groove, the leading end of the pull rod is rotatably connected with the I-shaped sliding block, and the tail end is rotatably connected with the corresponding horizontal sliding plate. The middle portion of the cross-shaped transmission frame is welded with a N-shaped mounting frame, and a positioning insertion shaft is slidingly installed in the N-shaped mounting frame in the form of spring pushing, and the leading end portion of the positioning insertion shaft penetrates into the T-shaped sliding groove and is in insertion fit with the I-shaped sliding block.

[0008] Further, four π-shaped transmission frames are symmetrically welded on the mutually opposite portions of the two semicircular mounting sleeves, two connecting short shafts are symmetrically welded on the outer periphery of the threaded ring, the tail end of the connecting rod is rotatably connected with the corresponding connecting short shaft, and the leading end is rotatably connected with one end of the longitudinal side shaft of the corresponding π-shaped transmission frame.

[0009] Further, when the two semicircular mounting sleeves are connected together, they jointly form a circular bearing seat for installing and positioning the deep groove ball bearing to be detected. The deep groove ball bearing is built-in the circular bearing seat, and the deep groove ball bearing is sleeved on the leading end portion of the main shaft and in abutting contact with the shaft shoulder provided on the portion.

[0010] Further, the driving device is also included, the power output shaft of the driving device is connected with the main shaft through a shaft coupling, and the middle portion of the main shaft is welded with a load wheel.

The vibration sensor, the noise sensor and the temperature sensor all establish communication with the central controller, and all three are electrically connected to the central controller.

[0014] The multiple detection equipment for deep groove ball bearings provided by the present invention has the following beneficial effects: 1. The two semicircular mounting sleeves are the two parts of the circular bearing seat, which are driven by an eight-crank slider mechanism for docking assembly and separation and disassembly. With this arrangement, it is only necessary to start the drive assembly, and the drive assembly can drive the two transverse threaded shafts to rotate synchronously forward and reverse, and control the two semicircular mounting sleeves to slide toward or back to complete the docking, locking and unlocking and separation operations of the two semicircular mounting sleeves at one time. Compared with the existing technology of using multiple threaded locking parts to implement splicing and locking of the bearing seat assembly with a spliced ​​and detachable structure, this can eliminate the tedious steps of manually tightening and loosening all the threaded locking parts in step by step when assembling and disassembling the bearing seat assembly, which helps to improve the assembly and disassembly efficiency of the bearing seat assembly and indirectly improve the disassembly and replacement rate of the deep groove ball bearings.

[0016] 3. Through the power transmission of the double crank slider mechanism, the sliding stripping operation of the stripping component can be driven jointly by the driving force when the two semicircular mounting sleeves slide back to back. This can save the trouble of additional manual operation of the stripping component to strip and disassemble the deep groove ball bearing. The operation is convenient and labor-saving. It can also save the need to configure an additional drive unit for the stripping component and the need to configure an automatic control system for the drive unit. The stripping component can indirectly use the driving force of the drive assembly to realize automatic stripping and disassembly of the deep groove ball bearing, which helps to reduce the power consumption and cost of the detection equipment.

[0017] Four, the setting of the empty space distance makes the two semicircle mounting sleeves contact with the two cross-shaped transmission frames to drive the stripping assembly to implement stripping and disassembling operation on the deep groove ball bearing after the deep groove ball bearing is completely exposed, which can avoid that the stripping assembly is in advance in contact with the deep groove ball bearing when the deep groove ball bearing is not completely exposed, and begins to strip and push the deep groove ball bearing, causing the stripping assembly to be broken by the deep groove ball bearing which is not completely separated from the two semicircle mounting sleeves and is still fixed and limited between the two semicircle mounting sleeves, and is helpful to ensure the integrity of the stripping assembly and the normal and effective implementation of the automatic stripping and disassembling operation.

[0036] The following is a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of the above features, as well as their role in implementing this technical solution: When the performance indicators of the deep groove ball bearing 11 are detected, first, the driving device 1 is started, and after the driving device 1 is started, the main shaft 3, the load wheel 4 and the deep groove ball bearing 11 to be detected which is installed on the leading end portion of the main shaft 3 and positioned in the circular bearing seat are rotated at high speed. When the load wheel 4 is rotated at high speed, a large centrifugal force is generated due to its large weight, and the centrifugal force is transmitted to the deep groove ball bearing 11 through the main shaft 3, which is used to simulate the load required to be borne by the deep groove ball bearing 11 under actual working conditions. The arrangement of the load wheel 4 makes the detection environment of the deep groove ball bearing 11 more close to the actual situation, which helps to improve the detection accuracy of the detection equipment for the deep groove ball bearing 11. During the detection process, the load applied by the load wheel 4 to the deep groove ball bearing 11 will cause the deep groove ball bearing 11 to generate friction heating, vibration and noise; the temperature sensor 12 can monitor the actual operating temperature of the deep groove ball bearing 11 in real time during the detection process. After the temperature sensor 12 detects the actual operating temperature signal, it transmits these temperature signals to the central controller in real time. After the central controller receives these temperature signals, it first quantizes these temperature signals into corresponding temperature values, then compares these real-time updated temperature values, and transmits the highest temperature value to the LED display screen arranged on the wall of the electric control box 10 in the form of real-time updating and covering. The temperature value finally displayed on the LED display screen is the highest actual operating temperature of the deep groove ball bearing 11 during the detection process. Finally, the highest actual operating temperature is compared with the standard operating temperature range designed for the deep groove ball bearing 11. If the highest actual operating temperature falls within the standard operating temperature range, it is determined that the temperature rise of the deep groove ball bearing 11 during operation is controllable, and its friction performance, lubrication state and heat dissipation performance are qualified. If the highest actual operating temperature is higher than the standard operating temperature range, it is determined that the friction performance, lubrication state and heat dissipation performance of the deep groove ball bearing 11 are unqualified.The vibration sensor 13 and the noise sensor 14 can monitor the actual running noise and vibration of the deep groove ball bearing 11 in real time during the detection process. After the vibration sensor 13 and the noise sensor 14 detect the actual noise and vibration signals, the signals are transmitted to the central controller. The central controller first quantizes the signals into corresponding decibel values, vibration frequency values and amplitude values. Then, the central controller compares the real-time updated values and transmits the highest value to the LED display screen in real-time update form. The highest decibel value displayed on the LED display screen represents the maximum running noise of the deep groove ball bearing 11 during the detection process. The highest vibration frequency and amplitude values displayed on the LED display screen represent the maximum vibration of the deep groove ball bearing 11 during the detection process. Finally, the highest decibel value is compared with the designed noise decibel value range of the deep groove ball bearing 11 in the standard running state, and the highest vibration frequency and amplitude values are compared with the designed standard running vibration frequency value range and running amplitude value range of the deep groove ball bearing 11. If the highest decibel value falls within the standard noise decibel value range, and the highest vibration frequency and amplitude values fall within the standard running vibration frequency value range and running amplitude value range, respectively, it is determined that the running noise and vibration of the deep groove ball bearing 11 are controllable, and the running stability is qualified. If the highest decibel value is higher than the standard noise decibel value range, and the highest vibration frequency and amplitude values are higher than the standard running vibration frequency value range and running amplitude value range, respectively, it is determined that the running stability of the deep groove ball bearing 11 is unqualified. After the detection operation is completed, the deep groove ball bearing 11 is disassembled from the first end portion of the main shaft 3 and the two semi-circular mounting sleeves 7 for replacement. The detection device can perform one-time multiple detection on the friction performance, lubrication state, heat dissipation performance and running stability of the deep groove ball bearing 11 through the temperature sensor 12, the vibration sensor 13 and the noise sensor 14.

[0037] The two semi-circular mounting sleeves 7, the eight connecting rods 703 and the two threaded rings 5041 jointly form a set of eight slider-crank mechanisms. Through the mechanism, the two transverse threaded shafts 504 are synchronously rotated forward and backward, which drives the threaded rings 5041 to slide towards or away from each other, and controls the two semi-circular mounting sleeves 7 to slide towards or away from each other. When the two semi-circular mounting sleeves 7 slide towards each other, they are connected together and the deep groove ball bearing 11 is assembled inside them. When the deep groove ball bearing 11 is assembled in the two semi-circular mounting sleeves 7, it is positioned and retained on the first end portion of the main shaft 3. When the two semi-circular mounting sleeves 7 slide away from each other, they separate from each other and expose the detected deep groove ball bearing 11 assembled therein for disassembly and replacement. Through the power transmission of the chain and the transverse transmission shaft 8, the drive assembly 2 can drive the two transverse threaded shafts 504 to synchronously rotate forward and backward.

[0038] The two semicircular mounting sleeves 7 are used as two parts of a circular bearing seat, and are connected and separated by an eight-crank slider mechanism. In this way, only the driving assembly 2 needs to be started to drive the two transversely arranged threaded shafts 504 to rotate synchronously in opposite directions, and to control the sliding of the two semicircular mounting sleeves 7 towards or away from each other, thereby completing the connection and separation of the two semicircular mounting sleeves 7 at one time. Compared with the prior art in which a bearing seat assembly with a detachable structure is connected by multiple threaded fasteners, the cumbersome step of manually rotating and loosening all the threaded fasteners in sequence during the assembly and disassembly of the bearing seat assembly can be omitted, which helps to improve the assembly and disassembly efficiency of the bearing seat assembly and indirectly improves the disassembly and replacement rate of the deep groove ball bearing 11.

[0039] The two cross-shaped transmission frames 6, the two pull rods 605, and the stripping assembly 9 are connected to form a double-crank slider mechanism. Through the mechanism, the two cross-shaped transmission frames 6 slide away from each other, which drives the stripping assembly 9 to slide towards the deep groove ball bearing 11. When the stripping assembly 9 slides towards the deep groove ball bearing 11, the collar 901 on the stripping assembly 9 near the deep groove ball bearing 11 contacts and abuts against the deep groove ball bearing 11, and the deep groove ball bearing 11 is completely stripped and disassembled from the first end portion of the main shaft 3. In this way, the double-crank slider mechanism is a stripping and disassembly mechanism integrated in the detection equipment to directly disassemble the deep groove ball bearing 11. The double-crank slider mechanism makes the present application more convenient than the prior art, which lacks a stripping and disassembly mechanism and needs to manually operate an external stripping tool in the cramped space between the load wheel 4 and the vertical support frame 5 to disassemble the deep groove ball bearing 11. The present application can avoid the need to adapt an external stripping tool and the manual operation of the external stripping tool in the cramped space, which helps to improve the convenience of stripping and disassembly of the deep groove ball bearing 11.

[0040] When the two semicircular mounting sleeves 7 are driven to slide away from each other for separation and disassembly, they can respectively abut against and push the two cross-shaped transmission frames 6 to slide away from each other, control the stripping assembly 9 to slide towards the deep groove ball bearing 11, and automatically disassemble the deep groove ball bearing 11. In this way, through the power transmission of the double-crank slider mechanism, the sliding stripping operation of the stripping assembly 9 can be driven by the driving force when the two semicircular mounting sleeves 7 slide away from each other. This can avoid the need to manually operate the stripping assembly 9 to disassemble the deep groove ball bearing 11, which is convenient and labor-saving. In addition, it can avoid the need to configure a driving unit for the stripping assembly 9 and an automatic control system for the driving unit, so that the stripping assembly 9 can indirectly utilize the driving force of the driving assembly 2 to automatically strip and disassemble the deep groove ball bearing 11, which helps to reduce the power consumption and cost of the detection equipment. When the two semicircular mounting sleeves 7 are separated from the deep groove ball bearing 11, they need to continue to slide away from each other to contact the two cross-shaped transmission frames 6, and drive the two cross-shaped transmission frames 6. In this process, the continuous sliding away of the two semicircular mounting sleeves 7 can expand the distance between them, which facilitates the replacement of the new deep groove ball bearing 11 on the first end portion of the main shaft 3 in the subsequent process.

[0041] When the deep groove ball bearing 11 is peeled off and disassembled, the two semicircular mounting sleeves 7 need to be controlled to slide away, exposing the deep groove ball bearing 11. When the two semicircular mounting sleeves 7 are in a butt joint combined state, there is a certain empty space between them and the two cross-shaped transmission frames 6 (see Figure 1 and Figure 3 ). During the process of sliding away of the two semicircular mounting sleeves 7, when the two semicircular mounting sleeves 7 are separated from the deep groove ball bearing 11 and the deep groove ball bearing 11 is completely exposed, the two semicircular mounting sleeves 7 completely slide through the empty space and contact the two cross-shaped transmission frames 6 to drive the two cross-shaped transmission frames 6. The setting of the empty space makes the two semicircular mounting sleeves 7 not in contact with the two cross-shaped transmission frames 6 until the deep groove ball bearing 11 is completely exposed, and the peeling assembly 9 is driven to peel off and disassemble the deep groove ball bearing 11. This can avoid the peeling assembly 9 from being in contact with the deep groove ball bearing 11 before the deep groove ball bearing 11 is completely exposed, and starting to peel off and push the deep groove ball bearing 11, causing the peeling assembly 9 to be pushed back and broken by the deep groove ball bearing 11 which is not completely separated from the two semicircular mounting sleeves 7 and is still fixed and limited between the two semicircular mounting sleeves 7. This helps to ensure the integrity of the peeling assembly 9 and the normal and effective implementation of the automatic peeling and disassembly work.

[0042] After the deep groove ball bearing 11 is peeled off and removed, the two semicircular mounting sleeves 7 are slid away from the sliding direction to the farthest distance, and the two cross-shaped transmission frames 6 are pushed by the two semicircular mounting sleeves 7 to keep the state of sliding away from the sliding direction and the farthest distance. In this state, the two cross-shaped transmission frames 6 can position and keep the peeled assembly 9 in the state of sliding towards the deep groove ball bearing 11 and being placed on the first end portion of the main shaft 3. The peeled assembly 9 in this state will block and hinder the replacement and installation of the new deep groove ball bearing 11 on the first end portion of the main shaft 3. Therefore, before the replacement and installation of the new deep groove ball bearing 11, the peeled assembly 9 needs to be slid back to the position away from the deep groove ball bearing 11, so as to leave space for the replacement and installation of the deep groove ball bearing 11 on the first end portion of the main shaft 3. When the positioning shaft 602 is inserted and matched with the I-shaped sliding block 604, the first end of the connecting rod 703 can be positioned in the rotating connection state of the middle part of the cross-shaped transmission frame 6. In this state, the first end of the connecting rod 703 is connected and transmitted with the cross-shaped transmission frame 6 through the I-shaped sliding block 604 and the positioning shaft 602. The cross-shaped transmission frame 6 can drive the connecting rod 703 to perform specified actions, so as to ensure the normal operation and use of the double-crank sliding block mechanism. When the peeled assembly 9 is kept on the first end portion of the main shaft 3, it compresses the springs on the two vertical guide shafts 5031 through the two horizontal sliding plates 904. In this state, the two positioning shafts 602 and the two I-shaped sliding blocks 604 are separated, the two I-shaped sliding blocks 604 are unlocked and released from the two cross-shaped transmission frames 6. After the two I-shaped sliding blocks 604 are released, the transmission between the two I-shaped sliding blocks 604 and the two cross-shaped transmission frames 6 is released, and the compression and holding force of the two I-shaped sliding blocks 604 on the two cross-shaped transmission frames 6 through the two I-shaped sliding blocks 604, the two connecting rods 703 and the two horizontal sliding plates 904 is also released. At this time, the two springs push the peeled assembly 9 back to the position away from the deep groove ball bearing 11, and are separated from the first end portion of the main shaft 3, leaving space for the replacement and installation of the deep groove ball bearing 11, which facilitates the replacement and installation of the new deep groove ball bearing 11 on the first end portion of the main shaft 3. When the peeled assembly 9 is pushed back to slide, it pulls and drives the two I-shaped sliding blocks 604 to slide along the two T-shaped sliding grooves 603 to the opposite end portions of the two cross-shaped transmission frames 6 through the two connecting rods 703. After that, when the two semicircular mounting sleeves 7 are driven to slide towards each other to be connected and combined and to position and install the newly replaced deep groove ball bearing 11, the two semicircular mounting sleeves 7 can be released from the pushing and holding of the two cross-shaped transmission frames 6. At this time, the two cross-shaped transmission frames 6 need to be manually slid back to the initial position, and the two positioning shafts 602 and the two I-shaped sliding blocks 604 are inserted and matched (refer to Figure 1 and Figure 3 ), so as to restore the transmission of the two I-shaped sliding blocks 604 and the two connecting rods 703 with the two cross-shaped transmission frames 6, and restore the double-crank sliding block mechanism to the state of normal operation and use, in preparation for the peeled assembly 9 to be peeled off and removed again.

[0043] When the new deep groove ball bearing 11 is replaced and installed, it is manually implemented by using an external installation tool. Since the friction heat generated by the deep groove ball bearing 11 during detection is transmitted to the main shaft 3 and the semicircular mounting sleeve 7, when the new deep groove ball bearing 11 is replaced and installed, the hands need to be worn with heat insulation gloves to avoid being scalded by the main shaft 3 and the semicircular mounting sleeve 7.
