Description

Technical Field

[0001] The utility model relates to the technical field of friction plate height detection, in particular to a clutch friction plate height detection device. Background Technique

[0002] During the assembly of the hybrid clutch friction plate, five friction plates and five separator plates need to be installed into the clutch housing. After the clutch has been used for a long time, the friction plates will wear out and need to be replaced. When manually measuring the thickness of the friction plates, the entire clutch needs to be disassembled to directly measure the friction plates. If there is a small amount of wear, it still needs to be reinstalled, and the measurement is relatively inconvenient.

[0003] The snap ring locks the friction plate to ensure that the friction plate will not come out during vibration, and the snap ring needs to be fully installed in place to prevent the snap ring from coming out during vibration. However, when manually installing the snap ring commonly, it is difficult to ensure that the snap ring is installed in place, which leads to the problem that the friction plate is prone to come out during vibration. Content of the Utility Model

[0004] In order to solve the problems of inconvenient measurement of friction plate wear and difficulty in detecting whether the snap ring is installed in place as mentioned in the above background technique, the utility model provides the following technical solutions:

[0005] A clutch friction plate height detection device includes a detection component for facilitating the detection of the friction plate inside the clutch;

[0006] An isolation plate is installed inside the clutch, and there are five isolation plates and five friction plates, and the isolation plates and the friction plates are arranged in an alternating manner.

[0007] The clutch includes a driving disc, a connecting plate is installed outside the driving disc, the detection component includes a pressing block for pushing the driving disc downward, the detection component includes a measuring rod in contact with the connecting plate, a middle substrate is installed at the upper end of the measuring rod, and the detection component includes a first sensor for facilitating the detection of the height of the friction plate in cooperation with the middle substrate.

[0008] Further, a snap ring is installed at the upper end of the clutch, and a clamping component for facilitating the installation of the snap ring is installed in the middle of the detection component.

[0009] Further, the clutch includes a housing, and a clamping groove for limiting the snap ring is opened on the inner wall at the upper end of the housing.

[0010] Further, the detection component includes a core shaft, an upper substrate for limiting the first sensor is installed at the upper end of the core shaft, a lower substrate is installed at the lower end of the detection component, and a first base is installed at the lower end of the upper substrate.

[0011] Further, a fourth pulling cylinder for controlling the up-and-down movement of the measuring rod is installed on one side of the middle substrate, and the fourth pulling cylinder is installed at the lower end of the first base.

[0012] Further, a second sensor for detecting the installation depth of the snap ring is installed at the lower end of the lower substrate. A connecting block is installed at the upper end of the second sensor. A limiting rod is installed at one end of the connecting block. A second base for limiting the clamping assembly is installed at the lower end of the lower substrate. A pressing block is installed at the lower end of the lower substrate. A third pulling cylinder for controlling the up-and-down movement of the pressing block is installed at the upper end of the pressing block.

[0013] Further, the clamping assembly includes a clamping block. Two inclined plates are installed at one end of the clamping block. A clamping rod for facilitating the clamping of the snap ring is installed at one end of the inclined plate. A middle groove is machined at one end of the clamping block close to the inclined plate. Oblique grooves are machined on both sides at one end of the clamping block close to the inclined plate.

[0014] Further, a push rod for cooperating with the inclined groove to control the two clamping rods to approach each other is installed in the cavity of the inclined groove. A limiting plate is installed at the upper end of the push rod. A limiting block is installed at the lower end of the push rod. A second pulling cylinder for controlling the movement of the limiting plate is installed on one side of the limiting plate. A first pulling cylinder for controlling the up-and-down movement of the clamping block is installed at the upper end of the clamping block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. When detecting the height of the friction plate, the fourth pulling cylinder controls the middle substrate to move downward, so that the bottom end of the measuring rod contacts the connecting plate. The first sensor scans the height of the upper surface of the middle substrate to obtain the first data A. Start the third pulling cylinder to drive the pressing block to push the driving disc downward, so that the connecting plate squeezes the isolation plate and the friction plate, making the isolation plate and the friction plate fit tightly. Control the fourth pulling cylinder to drive the middle substrate to move downward, so that the bottom end of the measuring rod contacts the upper surface of the connecting plate. The first sensor scans the height of the upper surface of the middle substrate to obtain the second data B. Subtract A from B to obtain the moving height when the isolation plate and the friction plate are in close contact. Compare with the movable height of the isolation plate and the connecting plate when there is no friction, and the worn height of the friction plate can be obtained. When the worn height increases due to friction to a value that requires replacement of the friction plate, the clutch can be disassembled and the snap ring inside the clutch can be replaced.

[0017] Second, when installing the circlip, place the clamping rod in the two hole cavities of the circlip, start the second pulling cylinder, drive the limiting plate to slide in the groove cavity of the inclined groove, so that the two inclined plates approach each other, and the clamping rod synchronously drives the two ends of the circlip to approach each other to clamp the circlip. Control the clamping block to move downward through the first pulling cylinder, so that the clamping rod is inserted into the inner cavity of the housing. When the circlip and the card slot are at the same level, the second pulling cylinder controls the limiting plate to reset, and the two clamping rods move away from each other, so that the circlip is gradually inserted into the groove cavity of the card slot. The depth of the groove cavity of the card slot is C, and the width of the circlip is D. The exposed width is scanned by the second sensor. When the exposed width is equal to the value of D minus C, it means that the circlip is installed in place. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The preferred specific embodiments for implementing the present invention are described in detail below, and a clear and complete description is made in combination with the drawings.

[0027] Please refer to Figures 1-4, the present utility model provides a clutch friction plate height detection device, which includes a detection component 200 for facilitating the detection of the friction plate 30 inside the clutch 100. A snap ring 10 is installed at the upper end of the clutch 100, and a clamping component 300 for facilitating the installation of the snap ring 10 is installed in the middle of the detection component 200.

[0028] An isolation plate 20 is installed inside the clutch 100. There are five isolation plates 20 and five friction plates 30, and the isolation plates 20 and the friction plates 30 are distributed alternately.

[0029] The clutch 100 includes a driving disk 110. A connecting plate 111 is fixedly installed on the outside of the driving disk 110. The clutch 100 includes a housing 120, and the isolation plates 20 and the friction plates 30 are located in the middle of the inner cavity of the housing 120. A clamping groove 121 for limiting the snap ring 10 is provided on the upper inner wall of the housing 120.

[0030] The detection component 200 includes a pressing block 260 for pushing the driving disk 110 downward. A third pulling cylinder 261 for controlling the up and down movement of the pressing block 260 is installed at the upper end of the pressing block 260. The detection component 200 includes a measuring rod 220 in contact with the connecting plate 111. A middle base plate 221 is fixedly installed at the upper end of the measuring rod 220. A fourth pulling cylinder 222 for controlling the up and down movement of the measuring rod 220 is fixedly installed on one side of the middle base plate 221. The detection component 200 includes a first sensor 250 for facilitating the detection of the height of the friction plate 30 in cooperation with the middle base plate 221.

[0031] When it is necessary to detect the height of the friction plate 30, the fourth pulling cylinder 222 controls the middle base plate 221 to move downward, so that the bottom end of the measuring rod 220 contacts the connecting plate 111. The first sensor 250 scans the upper surface height of the middle base plate 221 to obtain the first data A. The third pulling cylinder 261 is started to drive the pressing block 260 to push the driving disk 110 downward, so that the connecting plate 111 squeezes the isolation plates 20 and the friction plates 30, making the isolation plates 20 and the friction plates 30 stick tightly. The fourth pulling cylinder 222 is controlled to drive the middle base plate 221 to move downward, so that the bottom end of the measuring rod 220 contacts the upper surface of the connecting plate 111. The first sensor 250 scans the upper surface height of the middle base plate 221 to obtain the second data B. Subtracting A from B gives the moving height when the isolation plates 20 and the friction plates 30 are in close contact. By comparing with the movable height of the isolation plates 20 and the connecting plate 111 when there is no friction, the worn height of the friction plate 30 can be obtained. When the worn height increases due to friction to a value that requires the replacement of the friction plate 30, the clutch 100 can be disassembled and the snap ring 10 inside the clutch 100 can be replaced.

[0032] The detection component 200 includes a mandrel 210. An upper substrate 211 for limiting the first sensor 250 is fixedly installed at the upper end of the mandrel 210. A lower substrate 212 is fixedly installed at the lower end of the detection component 200. A first base 213 is fixedly installed at the lower end of the upper substrate 211, and the fourth drawing cylinder 222 is fixedly installed at the lower end of the first base 213.

[0033] A second sensor 230 for detecting the installation depth of the snap ring 10 is installed at the lower end of the lower substrate 212. A connecting block 231 is installed at the upper end of the second sensor 230. A limiting rod 232 is installed at one end of the connecting block 231. A second base 240 for limiting the clamping component 300 is fixedly installed at the lower end of the side of the lower substrate 212 close to the limiting rod 232, and the second base 240 is in an L-shaped structure.

[0034] The clamping component 300 includes a clamping block 310. Two inclined plates 313 are fixedly installed at one end of the clamping block 310. A clamping rod 314 for facilitating the clamping of the snap ring 10 is fixedly installed at one end of the inclined plate 313. When clamping the snap ring 10, the clamping rod 314 is inserted into the two cavities of the snap ring 10. A middle groove 311 is processed at one end of the clamping block 310 close to the inclined plate 313. Through the opening of the middle groove 311, it is convenient for the two inclined plates 313 to drive the two clamping rods 314 to approach each other to clamp the snap ring 10. Oblique grooves 312 are processed on both sides at one end of the clamping block 310 close to the inclined plate 313.

[0035] A push rod 320 for cooperating with the inclined groove 312 to control the two clamping rods 314 to approach each other is installed in the cavity of the inclined groove 312. A limiting plate 321 is fixedly installed at the upper end of the push rod 320. A limiting block 322 is fixedly installed at the lower end of the push rod 320. A second drawing cylinder 340 for controlling the movement of the limiting plate 321 is installed on one side of the limiting plate 321, and the second drawing cylinder 340 is installed on the left side of the second base 240. A first drawing cylinder 330 for controlling the up and down movement of the clamping block 310D is installed at the upper end of the clamping block 310, and the first drawing cylinder 330 is installed at the lower end of the second base 240.

[0036] When installing the circlip 10, place the clamping rod 314 in the two hole cavities of the circlip 10, start the second pulling cylinder 340, drive the limiting plate 321 to slide in the cavity of the inclined groove 312, so that the two inclined plates 313 approach each other, and the clamping rod 314 synchronously drives the two ends of the circlip 10 to approach each other to clamp the circlip 10. Control the clamping block 310 to move downward through the first pulling cylinder 330, so that the clamping rod 314 is inserted into the inner cavity of the housing 120. When the circlip 10 and the card slot 121 are at the same level, the second pulling cylinder 340 controls the limiting plate 321 to reset, and the two clamping rods 314 move away from each other, so that the circlip 10 is gradually inserted into the cavity of the card slot 121. The depth of the cavity of the card slot 121 is C, and the width of the circlip 10 is D. The exposed width is scanned by the second sensor 230. When the exposed width is equal to the value of D minus C, it indicates that the circlip 10 is installed in place.
