Description

Technical Field

[0001] The invention relates to the technical field of isolator measurement, in particular to a vehicle isolator calibration and measurement device. Background Art

[0002] One-way clutches are widely used in vehicle clutches, starters and other components. Their main principle is that they can rotate in one direction and automatically lock in the reverse direction. Among the one-way clutches, they are mainly divided into roller type one-way clutches and wedge type one-way clutches. The wedge type one-way clutch mainly uses a circle of wedges. When the inner and outer rings of the one-way clutch rotate, the wedges are automatically rubbed against the inner and outer rings to lock. The one-way clutches in large vehicles are larger in size and have higher requirements for their locking stability. In their production and manufacturing work, it is necessary to ensure their anti-torque effect and wedge accuracy. The current calibration and measurement device for automobile one-way clutches is not convenient for torque detection. Deformation detection is carried out during measurement. The deformation detection of the outer ring of the one-way device relies on measuring tools such as calipers, which is not comprehensive enough and is easy to miss. It is also not convenient to automatically test the consistency of the wedge blocks of the one-way device when locked. Although the one-way device is locked, some wedge blocks do not meet the displacement stroke standards due to the large gap between the inner and outer rings when locked. Long-term use will cause inconsistent wear of a circle of wedge blocks, affecting the torque resistance of the one-way device. Irregular wedge blocks are difficult to measure manually, which directly affects the service life of the one-way device. It is also not convenient to quickly screen wedge blocks that do not meet the accuracy standards. The detection efficiency is low and the missed detection rate is high.

[0003] Therefore, we propose a vehicle one-way brake calibration and measurement device. Summary of the invention

[0036] The clamping detection part 3 includes: a detection clamping plate 301, a rubber fitting pad 3011 and a deformation detection tube 302.

As the one-way device is subjected to torque lock, the wedge block of the one-way device will squeeze the inner and outer rings of the one-way device. At this time, the outer ring of the one-way clutch will be squeezed and deformed by the wedge as the torque continues to increase, especially for the thin-walled outer ring, the middle part will be easily squeezed and protruded by the wedge. At this time, the rubber fitting pad 3011 attached to the outer ring of the one-way clutch will be pressed inward, and then squeeze the injected pure water inside the detection clamping plate 301. At this time, the deformation piston 303 will be squeezed in the deformation detection cylinder 302 and slide outward, squeezing the outer ring pressure sensor 304, and displaying the data through an external display.

[0037] The lifting control unit 4 includes: a lifting hydraulic cylinder 401, a lifting frame 402 and a limit shaft 403. There are two lifting hydraulic cylinders 401. The output shafts of the two lifting hydraulic cylinders 401 are respectively fixedly mounted on the two propulsion mounting seats 103; the two lifting hydraulic cylinders 401 are fixedly mounted with the lifting frames 402; the two propulsion mounting seats 103 are respectively fixedly mounted with two limit shafts 403; the four limit shafts 403 are slidably mounted with the lifting frames 402; the locking adapter The invention comprises: a rotating adapter ring 501, a sliding groove 5011, a toggle electromagnet 502, a dial 503 and a sliding sleeve 504. The rotating adapter ring 501 is rotatably mounted on the lifting frame 402. The rotating adapter ring 501 is provided with a circle of sliding grooves 5011. The rotating adapter ring 501 is coaxial with the isolator. Two toggle electromagnets 502 are fixedly mounted on the inner side of the circle of sliding grooves 5011. The rotating adapter ring 501 is fixedly mounted with a dial 503, and the dial 503 is provided with a circle of scales; a sliding sleeve 504 is slidably installed in each of the sliding grooves 5011, and each of the sliding sleeves 504 is provided with a hexagonal hole; a circle of sliding sleeves 504 is used to slide and adjust a circle of wedges on the corresponding one-way device; the electromagnet 502 is used to magnetically attract the sliding sleeve 504; each of the sliding sleeves 504 is provided with a pointer corresponding to the scale plate 503; the wedge block positioning member 6 includes: a sliding column 601, a wedge block fitting sheet 602 and a wedge block electromagnet Magnet 6021, sliding column 601 is a hexagonal column structure; sliding column 601 is slidably plugged into sliding sleeve 504; two wedge block fitting pieces 602 are fixedly installed at the bottom of sliding column 601, and the two wedge block fitting pieces 602 are used to fit and plug on both sides of the one-way device wedge, and the inner contours of the two wedge block fitting pieces 602 are consistent with the side of the one-way device wedge; a wedge block electromagnet 6021 is fixedly embedded at the bottom of sliding column 601, and the wedge block electromagnet 6021 is used to magnetically attract the one-way device wedge;The top of the sliding column 601 is an iron metal structure. This structure adopts a wedge block positioning piece 6, which cooperates with the locking adapter 5, so that the staff can perform displacement detection on a circle of wedge blocks at one time, and can detect the consistency of the wedge blocks when locked. If there is a local inconsistency in a circle of wedge blocks, it can be measured in time and intuitively to prevent the local wedge blocks from being locked in place due to factors such as poor accuracy. This structure utilizes the rotational displacement of the wedge blocks when locked, and the detection is direct and efficient, avoiding excessive wear of some wedge blocks. This structure uses the wedge block fitting piece 602 to adapt and position the one-way device wedge block, which can ensure detection accuracy and is easy to install, avoiding the low accuracy of the traditional manual measurement method. At the same time, the caliper is difficult to measure, and factors such as manual hand shaking will also cause the wedge to passively move, further affecting the problem of detection accuracy. By inserting the wedge fitting piece 602 into the middle of the wedge to fit and position it, when the one-way device is driven to perform torque testing, the wedge will also be driven to rotate by friction during the rotation of the inner and outer rings until it is locked. At this time, as the wedge rotates, it will drive the wedge fitting piece 602 to rotate at the same time, and the sliding column 601 will rotate to drive the sliding sleeve 504, and the pointer on the sliding sleeve 504 will also be displaced on the dial 503 accordingly. The staff can compare whether the displacement of the pointers on each sliding sleeve 504 is consistent before and after the one-way device is driven and locked. ;

[0038] Embodiment 2, on the basis of embodiment 1, the wedge block positioning member 6 also includes: an elastic adapter spring 603 and a wedge block locking pressure sensor 604, which can adopt HZC-H1 type wedge block locking pressure sensor 604, outer ring pressure sensor 304 and rotary pressure sensor 202, and adopt a matching display, two elastic adapter springs 603 are sleeved on the sliding column 601; the two elastic adapter springs 603 are respectively located on both sides of the sliding sleeve 504, and the other ends of the two elastic adapter springs 603 are respectively fixedly installed on the sliding column 601; the wedge block locking pressure sensor 604 is fixedly installed on the top of the sliding column 601, and the wedge block locking pressure sensor 604 is used to detect the one-way device The wedge block is loose; the wedge block locking pressure sensor 604 is externally connected to a display; the wedge block loosening control component 7 includes: a magnetic limit cylinder 701 and a constant pressure electromagnet 702, the magnetic limit cylinder 701 is fixedly installed inside the rotating adapter ring 501; a constant pressure electromagnet 702 is fixedly embedded on the magnetic limit cylinder 701; the constant pressure electromagnet 702 is magnetically connected to the top of the sliding column 601; the bottom of the constant pressure electromagnet 702 squeezes and fits the wedge block locking pressure sensor 604. This structure uses the constant pressure electromagnet 702 in conjunction with the wedge block locking pressure sensor 604, which can be used to detect the stability of a circle of wedge blocks after locking, and can avoid the local wedge blocks rotating to fit the inner and outer circles at the same time during torque detection, but The friction locking pressure of individual wedge blocks does not meet the standard, which is a problem that is difficult to be detected manually. This structure can further optimize the detection accuracy of the locking adapter 5. By applying pressure, this structure can set the magnetic force of the toggle electromagnet 502 and the elastic force of the elastic adapter spring 603 according to needs. This structure uses a method of loosening detection of the wedge blocks to actively apply pressure to avoid missed detection and ensure the production accuracy of the wedge-type one-way device. At the same time, the detection of this structure uses digital display, which is intuitive and accurate, to ensure that the staff can quickly screen the matching accuracy of each wedge block. Before the one-way device is locked for torque detection, there is a normal gap between the wedge blocks. First, the wedge blocks are driven up to the top of the gap, and then the wedge block is started. The dynamic drive motor 102 controls the locking of the one-way device. At this time, the wedge block will be locked tightly against the inner and outer rings of the one-way device. At this time, the constant pressure electromagnet 702 is powered off, and the elastic adapter spring 603 is reset and squeezed to generate downward pressure. If there is a gap between the wedge block and the inner and outer rings of the one-way device, or the friction is too small, the wedge block will be squeezed downward at this time, and the pressure detected by the wedge block locking pressure sensor 604 will be reduced. The two toggle electromagnets 502 are used to magnetically attract the sliding sleeve 504 in two directions respectively. At this time, the sliding sleeve 504 will drive the wedge block fitting sheet 602 to toggle the wedge block. If the wedge block is loose, the pointer on the sliding sleeve 504 can be used to observe the corresponding dial 503, and the detection is direct and accurate.

[0039] The working principle of this embodiment is as follows: First, insert the inner ring of the one-way device into the inner ring installation tube 203. At this time, the outer ring of the one-way device is clamped by the clamping detection part 3. By tightening the clamping screw 104, the detection clamping plate 301 can be driven to move, squeeze and fit the outer ring of the one-way device; before the one-way device is locked for torque detection, the top of the sliding column 601 is first magnetically attracted by the constant pressure electromagnet 702. At this time, the wedge block fitting sheet 602 is correspondingly fitted and inserted into the middle of the wedge block, and the wedge block electromagnet 6021 is energized to magnetically attract the wedge block. , the lifting hydraulic cylinder 401 drives the wedge block electromagnet 6021 to move up. At this time, a circle of wedge blocks are not locked by rotation, and there is a certain amount of clearance. The wedge blocks are driven to move up to the top of the gap. As the drive motor 102 drives the torque output cylinder 201 to rotate, the torque output cylinder 201 drives the rotary pressure sensor 202 to squeeze and fit the inner ring installation cylinder 203. At this time, the inner ring installation cylinder 203 is driven to generate a rotational torque, thereby controlling the rotation of the inner ring of the one-way device. At this time, the rotation direction of the one-way device is When the wedge is driven to be in a locked state, the wedge will be locked against the inner and outer rings of the one-way device. At this time, the constant pressure electromagnet 702 is powered off, and the elastic adapter spring 603 is reset and squeezed to generate downward pressure. If there is a gap between the wedge and the inner and outer rings of the one-way device, or the friction is too small, the wedge will be squeezed downward, and the wedge locking pressure sensor 604 at the corresponding position will also be driven to move downward, so that the pressure detected by the wedge locking pressure sensor 604 will be reduced. Through the external display, the staff can observe the data displayed on the external display of each wedge locking pressure sensor 604 to understand the looseness of the wedge. Similarly, by opening the two toggle electromagnets 502 in each sliding groove 5011 respectively, the two toggle electromagnets 502 are turned on in turn, and the sliding sleeves 504 can be magnetically attracted in two directions respectively. At this time, the sliding sleeve 504 will drive the wedge fitting sheet 602 to toggle the wedge. If the wedge is loose, the pointer on the sliding sleeve 504 can be used to observe the corresponding dial 503;

[0040] The lifting frame 402 is driven down by the lifting hydraulic cylinder 401, and then the rotating adapter ring 501 is driven down. At this time, the wedge block fitting piece 602 is correspondingly inserted into the middle of the wedge block for fitting and positioning. During the process, the sliding sleeve 504 slidably arranged in the sliding groove 5011 can be adjusted to adjust the position of the wedge block fitting piece 602 to fit and insert the middle of the wedge block. The wedge block can be magnetically attracted to position by energizing the wedge block electromagnet 6021, and then the one-way device is driven to perform a torque test. During the rotation of the inner and outer rings, the wedge block will also be driven by friction to rotate until it is locked. After the one-way device is locked, the torque output cylinder 201 drives the rotary pressure sensor 202 to squeeze and fit the inner ring mounting cylinder 203. The external display of the rotary pressure sensor 202 is used to display the real-time torque pressure. During this process, as the wedge block rotates, it will drive the wedge block fitting piece 602 to rotate at the same time, and the sliding column 601 will rotate to drive the sliding sleeve 504, and the pointer on the sliding sleeve 504 will also move to the dial 503. Displacement should be generated. The staff can compare whether the displacement of the pointers on each sliding sleeve 504 is consistent before and after the one-way device is driven and locked. If the pointers on some sliding sleeves 504 do not deviate or the displacement is small, it means that the friction between the corresponding wedge block and the inner and outer rings of the one-way device does not meet the standard or the manufacturing accuracy of the wedge block is poor; as the pressure of the one-way device being locked by torque continues to increase, the wedge block of the one-way device will squeeze the inner and outer rings of the one-way device. At this time, the outer ring of the one-way device will be squeezed and deformed by the wedge block as the torque increases. At this time, the rubber fitting pad 3011 attached to the outer ring of the one-way device will be pressed inward, thereby squeezing the pure water inside the detection clamping plate 301. At this time, the deformation piston 303 will be squeezed in the deformation detection cylinder 302 to slide outward, squeezing the outer ring pressure sensor 304, and the data will be displayed on the display external to the outer ring pressure sensor 304. Once the parameter change exceeds the standard, the pressure data displayed on the display corresponding to the rotary pressure sensor 202 can be immediately observed, that is, the maximum compressive resistance value of the deformation of the one-way device.
