Description

Technical Field

[0001] The present invention belongs to the technical field of tensioner processing devices and methods, and particularly relates to a hydraulic tensioner cutting processing device and method. Background Art

[0002] A hydraulic tensioner is a belt tensioning device used in an automotive transmission system, mainly used to compensate for the elongation of the belt due to wear and reduce the vibration of the belt during operation, thereby extending the service life of the belt. The hydraulic tensioner generates a force through a hydraulic system to tightly press the belt against the working pulley, ensuring that the belt works under appropriate pressure and preventing slippage.

[0003] The hydraulic tensioner generates a force through a hydraulic system and presses the belt tightly against the working pulley through the pressure of the hydraulic oil. This design enables the belt to work under appropriate pressure, neither slipping nor being damaged due to excessive pressure. If the tension force is too large, it will cause an increase in the belt load, premature damage, and at the same time, it will also damage the bearings of the working pulley. When the tensioner performs grinding and cutting work through a grinding wheel, when facing tensioners with different diameters, it is necessary to replace and adjust the position of the grinding wheel, which is inconvenient for manual operation and affects the improvement of work efficiency. Moreover, multiple power sources are required to drive the respective rotations of the tensioner and the grinding wheel respectively. The structural design is relatively complicated, the power source consumption is too large, resulting in waste of resources. In addition, during the subsequent cleaning process of the tensioner, during the cutting process, since more impurities are easily adsorbed on the outer wall edge of the tensioner, it is necessary to increase the water flow at its edge during the cleaning process. However, there are often fewer impurities attached to the center of the outer wall of the tensioner, so it can be cleaned without too much water flow. However, the existing spraying devices often adjust the overall flow rate and cannot perform the flow rate corresponding adjustment work at multiple positions thereof. Therefore, it also affects the improvement of the cleanliness of the tensioner. Summary of the Invention

[0004] The purpose of the present invention is to provide a hydraulic tensioner cutting processing device and method to solve the technical problems that when facing tensioners with different diameters, it is necessary to replace and adjust the position of the grinding wheel, which is inconvenient for manual operation and affects the improvement of work efficiency, and multiple power sources are required to drive the respective rotations of the tensioner and the grinding wheel respectively. The structural design is relatively complicated and the power source consumption is too large.

[0006] Furthermore, both sides of the swing rod are mounted on the first slider and the piston rod of the second cylinder by means of rotational connection, the first slider is provided with a second strip hole along the length direction of the baffle, and the second strip hole is symmetrically arranged relative to the center of the baffle.

[0007] Furthermore, a first gear plate is integrally formed with the first slider, and a second gear plate that moves in the opposite direction is transmitted through rotating gear meshing at the bottom of the first gear plate. The first gear plate, rotating gear and second gear plate are all placed in a cover body on the baffle, and an extending end at the bottom of the second gear plate is connected to an adjusting wheel placed on the side wall of the first conveyor belt.

[0008] Furthermore, a movable cavity is formed between the first gear plate, the rotating teeth, the second gear plate and the inner wall of the cover body, and a rolling groove connected to the extended end of the second gear plate is provided on the edge of the outer wall of the regulating wheel.

[0009] Furthermore, it also includes a deep cleaning mechanism, which includes a rotating wheel, and the rotating wheel and the output shaft of the driving motor are connected by a second conveyor belt transmission. One end of the rotating wheel extends to a reciprocating screw inside the box body, and a second slider fixed on a U-shaped rod is spirally driven on the reciprocating screw. Both ends of the U-shaped rod pass through the box body and are connected to a push rod, and one end of the push rod extends to an interference block inside the corner of the catheter.

[0010] Furthermore, one end of the conduit is connected to a water tank placed on the bottom plate through a pump body, and the resistance block is connected to a cleaning brush placed outside the nozzle through a synchronization rod. The cleaning brush is connected to the synchronization rod by plug-in installation, and both ends of the outer wall of the resistance block are provided with inclined surfaces.

[0011] Furthermore, partitions are fixedly installed at both ends of the inner wall of the nozzle, and one end of the partition is integrally connected with a trapezoidal block close to the resistance block. The inclined portion on the trapezoidal block is adaptively connected with the inclined surface on the resistance block. As the push rod drives the resistance block to move back and forth, the trapezoidal block and the inclined surface are separated from or in resistance to each other.

[0012] Furthermore, the partition is provided with a guide groove extending to the side wall of the nozzle, a first guide cavity and a second guide cavity are formed between the partitions and between the partition and the side wall of the nozzle respectively, and a conical opening extending to the cleaning brush is provided on the outer wall of the second guide cavity.

[0013] A hydraulic tensioner cutting method comprises the following steps: S1.1. Place the tension wheel between the baffle plate and the movable plate.

When cutting tension wheels of different diameters, the second cylinder is started to drive the height of the grinding wheel to achieve lifting and lowering activities, and the adjusting wheel synchronously adjusts the tightness of the first conveyor belt. At the same time, the spacing between the guide wheels at both ends is limited and adjusted according to the size of the tension wheel; S1.3, step S1.2 During the start-up process of the driving motor, the reciprocating screw is driven to rotate. Under the action of the spiral transmission, the push rod moves back and forth inside the catheter, and the flow rates in the first guide chamber and the second guide chamber in the nozzle are adaptively adjusted.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: A cutting guiding mechanism is set up. First, by starting the first cylinder, the tensioning wheel can be placed between the movable plate and the baffle and rotated by the output shaft of the driving motor. Under the driving action of the conveyor belt, the grinding wheel on the driven wheel can grind and cut the rotating tensioning wheel. The contact surfaces of the tensioning wheel and the grinding wheel are in contact in a way of relative rotation in the same direction. With the rotational speed difference between the two, the grinding wheel can quickly cut the tensioning wheel. In addition, in cooperation with the second cylinder, the height of the grinding wheel can be adjusted up and down, so as to be applicable to the cutting work of tensioning wheels with different diameters. Moreover, during the pushing process of the second cylinder, with the rotational connection of the swing rod, the distance between the guiding wheels on the bending plate can be adjusted adaptively, so as to play a role in limiting and guiding the outer wall of the tensioning wheel and prevent the position deviation during rotation. And under the action of gear meshing transmission, by horizontally pulling the adjusting wheel, the tension of the first conveyor belt can be adjusted to be tightened or loosened, so as to ensure that the power of the driving motor is effectively transmitted to the grinding wheel, thus ensuring the stability of the device operation. A deep cleaning mechanism is set up. After the driving motor is started, the power can be transmitted to the reciprocating lead screw. With the action of screw drive, the second slider can drive the U-shaped rod to move back and forth, and then the push rod can move back and forth inside the nozzle. During the movement of the push rod, the inclined surface on the abutting block can be separated from or attached to the trapezoidal block, so that the water flow rates in the first diversion cavity at the center of the nozzle and the second diversion cavities on both sides can be changed separately adaptively, so as to adapt to the cleaning of the surfaces of different tensioning wheels after cutting. Moreover, the tapered openings on the second diversion cavities can further pressurize the water flow, so that the outer wall edge of the tensioning wheel can be effectively cleaned directly by water flushing. At the same time, when the abutting block moves towards the trapezoidal block, it can seal the first diversion cavity, and then the water can only enter the second diversion cavity through the diversion groove. In this way, the water pressure can be increased by reducing the flow area, so as to carry out the corresponding cleaning work and improve the cleanliness of the tensioning wheel surface. (3) The whole cutting processing method is simple to operate, can quickly carry out the centering and clamping installation work of the tensioning wheel, effectively ensuring the safety of the cutting work of the tensioning wheel. When cutting tensioning wheels of different sizes, it can also adaptively adjust the limiting and guiding distance, and at the same time can adjust the tension of the first conveyor belt.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Manual Attached Figure 1 and attached Figure 2 As shown, a hydraulic tension wheel cutting processing device comprises: a bottom plate, a baffle 1 is fixedly mounted on one side of the top of the bottom plate, and a movable plate 3 connected to a first cylinder 2 is provided on the other side; The cutting guide mechanism 4 includes a driving motor 5 fixed on the bottom plate, the output shaft of the driving motor 5 passes through the driving wheel 6 and the baffle 1 and extends to the tension wheel 7, the driving wheel 6 and the driven wheel 8 are connected by a first conveyor belt 9, the movable shaft at one end of the driven wheel 8 is connected to the grinding wheel 10 placed between the baffle 1 and the movable plate 3, and both ends of the movable shaft are connected with first strip holes along the height direction of the baffle 1 and the movable plate 3; A second cylinder 11 is detachably mounted on the outer wall of the baffle 1 via a bracket, the piston rod on the second cylinder 11 is connected to a guide ring 12 on the outer wall of the movable shaft, and both ends of the piston rod on the second cylinder 11 are connected to the first slider 13 via a swing rod 14, a bending plate 16 is mounted on one end of the first slider 13 via a compression spring 15, and the bending plate 16 is rotatably connected to guide wheels 17 placed on both sides of the tensioning wheel 7.

[0020] A cutting guide mechanism 4 is provided. First, by starting the first cylinder 2, the tension wheel 7 can be placed between the movable plate 3 and the baffle 1 and rotated by the output shaft of the driving motor 5. Under the transmission action of the conveyor belt, the grinding wheel 10 on the driven wheel 8 can be driven to grind and cut the rotating tension wheel 7. The contact surfaces of the tension wheel 7 and the grinding wheel 10 are in contact in a manner of relative rotation in the same direction. With the rotation differential between the two, the tension wheel 7 can be quickly cut by the grinding wheel 10. In addition, with the second cylinder 11, the height of the grinding wheel 10 can be raised and lowered, so that it can be applied The tensioning wheel 7 with different diameters can be cut, and during the pushing process of the second cylinder 11, the spacing between the guide wheels 17 on the bending plate 16 can be adaptively adjusted by means of the rotation connection of the swing rod 14, so as to play a limiting and guiding role for the outer wall of the tensioning wheel 7 to prevent position deviation during the rotation process, and under the gear meshing transmission, the tension of the first conveyor belt 9 can be adjusted by horizontally pulling the adjusting wheel 22, so as to ensure that the power of the driving motor 5 is effectively transmitted to the grinding wheel 10, thereby ensuring the stability of the device operation.

[0021] Reference Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The swing rod 14 is installed on the piston rods of the first slider 13 and the second cylinder 11 on both sides by means of rotational connection. The first slider 13 is provided with a second strip-shaped hole along the length direction of the baffle 1, and the second strip-shaped hole is symmetrically arranged relative to the center of the baffle 1.

[0022] The swing rod 14 can drive the first sliders 13 at both ends to move in opposite directions by means of rotational connection. During the opposite movement of the first sliders 13, the distance between the guide wheels 17 can be adjusted to limit and guide the tension wheels 7 with different diameters.

[0023] Specifically, when the diameter of the tension wheel 7 is large, the second cylinder 11 drives the movable shaft on the guide ring 12 to move upward, and then the grinding wheel 10 connected to the driven wheel 8 moves upward synchronously, so as to adapt to the tension wheel 7 with a large diameter and contact and fit with it. Moreover, during the upward movement of the driven wheel 8, the transmission distance of the first conveyor belt 9 needs to be shortened so as to effectively transmit the power to the driven wheel 8, and the distance between the guide wheels 17 needs to be increased so as to adapt to the grinding and cutting work of the tension wheel 7 with a large diameter. On the contrary, when the diameter of the tension wheel 7 is small, the second cylinder 11 drives the movable shaft on the guide ring 12 to move downward, and then the grinding wheel 10 connected to the driven wheel 8 moves downward synchronously, so as to adapt to the tension wheel 7 with a small diameter and contact and fit with it. Moreover, during the downward movement of the driven wheel 8, the transmission distance of the first conveyor belt 9 needs to be lengthened so as to effectively transmit the power to the driven wheel 8.

[0024] The driving wheel 6 and the driven wheel 8 are connected by transmission through the first conveyor belt 9, and the transmission ratio between the driving wheel 6 and the driven wheel 8 is set to 1:2 or 1:3. In this way, during the relative rotational cutting in the same direction on the contact surface between the tension wheel 7 and the grinding wheel 10, by setting different transmission ratios, the cutting speed can be further increased through different rotational speeds.

[0025] Reference Figure 1 、 Figure 3 and Figure 6 A first gear plate 18 is integrally formed and connected to the first slider 13. The bottom of the first gear plate 18 is meshed and driven by a rotating tooth 19 with a second gear plate 20 moving in the opposite direction. The first gear plate 18, the rotating tooth 19 and the second gear plate 20 are all placed in a cover body 21 on the baffle 1. The extended end at the bottom of the second gear plate 20 is connected with an adjusting wheel 22 placed on the side wall of the first conveyor belt 9.

[0026] An activity cavity 23 is formed between the first gear plate 18, the rotating tooth 19, the second gear plate 20 and the inner wall of the cover body 21. A rolling groove is provided at the outer wall edge of the adjusting wheel 22 and is connected to the extended end of the second gear plate 20.

[0027] refer to Figure 2 , Figure 7 and Figure 8 A hydraulic tensioning wheel cutting processing device also includes a deep cleaning mechanism 24, which includes a rotating wheel 25. The rotating wheel 25 and the output shaft of the driving motor 5 are connected through a second conveyor belt 26. One end of the rotating wheel 25 extends to a reciprocating screw 28 inside a box body 27. The reciprocating screw 28 is spirally driven with a second slider 30 fixed on a U-shaped rod 29. Both ends of the U-shaped rod 29 pass through the box body 27 and are connected to a push rod 31. One end of the push rod 31 extends to a resistance block 33 inside the corner of the guide tube 32.

[0028] One end of the conduit 32 is connected to a water tank 35 placed on the bottom plate through a pump body 34, and a cleaning brush 38 placed outside the nozzle 37 is connected to the abutment block 33 through a synchronization rod 36. The cleaning brush 38 is connected to the synchronization rod 36 by plug-in installation. Inclined surfaces 39 are provided at both ends of the outer wall of the abutment block 33.

[0029] Specifically, partitions 40 are fixedly installed at both ends of the inner wall of the nozzle 37, and one end of the partition 40 is integrally connected with a trapezoidal block 41 close to the resistance block 33. The inclined portion on the trapezoidal block 41 is adaptively connected to the inclined surface 39 on the resistance block 33. As the push rod 31 drives the resistance block 33 to move forward and backward, the trapezoidal block 41 and the inclined surface 39 are separated from each other or are in resistance and fit.

[0030] A guide groove 42 extending to the side wall of the nozzle 37 is formed on the partition 40, and a first guide cavity 43 and a second guide cavity 44 are formed between the partitions 40 and between the partitions 40 and the side wall of the nozzle 37 respectively. A conical opening 45 extending to the cleaning brush 38 is formed on the outer wall of the second guide cavity 44.

[0031] A deep cleaning mechanism 24 is provided. After the driving motor 5 is started, power can be transmitted to the reciprocating lead screw 28. With the action of screw drive, the second slider 30 can drive the U-shaped rod 29 to move back and forth, so that the push rod 31 moves back and forth inside the nozzle 37. During the movement of the push rod 31, the inclined surface 39 on the contact block 33 can be separated from or attached to the trapezoidal block 41. In this way, the water flow rates in the first diversion cavity 43 at the center of the nozzle 37 and the second diversion cavities 44 on both sides can be adaptively changed separately, so as to adapt to the cleaning surfaces of the tension pulleys 7 after different cuttings. Moreover, the tapered opening 45 on the second diversion cavity 44 can further pressurize the water flow, so that the outer wall edge of the tension pulley 7 can be effectively cleaned by directly flushing with water. At the same time, when the contact block 33 moves towards the trapezoidal block 41, it can block the first diversion cavity 43. Then the water can only enter the second diversion cavity 44 through the diversion groove 42. In this way, the water pressure can be increased by reducing the flow area, so as to carry out the corresponding cleaning work and improve the cleaning degree of the surface of the tension pulley 7.

[0032] When deep cleaning is required, the push rod 31 can move back and forth in the conduit 32 and can drive the contact block 33 to separate or close on the trapezoidal block 41. During the separation process, water will enter the first diversion cavity 43 and the second diversion cavity 44, and the water will be sprayed onto the tension pulley 7 at the same time. Cooperating with the cleaning brush 38 that moves to the outer surface of the tension pulley 7 during the separation, it can play a role in rotational cleaning. During the closing process, the water will enter the second diversion cavity 44 concentratedly through the diversion groove 42, the water flow increases, and cooperating with the tapered opening 45 can further increase the water flow. By means of pressurized cleaning, the outer wall edge of the tension pulley 7 can be effectively cleaned accordingly.

[0033] Reference Figure 9 , a hydraulic tension pulley cutting processing method, comprising the following steps: S1.1. Place the tension pulley 7 between the baffle 1 and the movable plate 3. Under the pushing action of the first cylinder 2, the positioning shaft on the movable plate 3 is inserted into the positioning hole, and the positioning hole on the tension pulley 7 is aligned with the output shaft of the driving motor 5; S1.2. Start the driving motor 5. Under the action of mechanical transmission, it can drive the rotation of the tension pulley 7. At the same time, the driven wheel 8 drives the grinding wheel 10 to grind and cut the outer surface of the tension pulley 7. When cutting tension pulleys 7 of different diameters, start the second cylinder 11 to drive the height of the grinding wheel 10 to move up and down, and the adjusting wheel 22 synchronously adjusts the tightness of the first conveyor belt 9. At the same time, the distance between the two end guide wheels 17 is limited and adjusted according to the size of the tension pulley 7; S1.3. During the startup process of the driving motor 5 driven in step S1.2, the reciprocating lead screw 28 is driven to rotate. Under the action of screw transmission, the push rod 31 moves back and forth inside the conduit 32, and the flow rates in the first diversion chamber 43 and the second diversion chamber 44 in the spray head 37 are adaptively adjusted. Cooperating with the cleaning brush 38, the outer wall surface of the tension pulley 7 can be effectively cleaned.

[0034] The whole cutting processing method is simple to operate, and can quickly center and clamp the tension pulley 7 for installation, effectively ensuring the safety of the cutting work on the tension pulley 7. When cutting tension pulleys 7 of different sizes, it can also adaptively adjust the limiting and guiding distance, and at the same time can adjust the tightness of the first conveyor belt 9. Moreover, the operation method has a high degree of automation and strong integrated design, ensuring the simultaneous operation of multiple transmission components with strong linkage. Moreover, it can deeply clean the rotating tension pulley 7, improving the product quality.

A first flow guiding cavity (43) and a second flow guiding cavity (44) are respectively formed between the partition plates (40) and between the partition plates (40) and the side wall of the spray head (37). A tapered opening (45) extending to the cleaning brush (38) is provided on the outer wall of the second flow guiding cavity (44).

9. A cutting and machining method for a hydraulic tensioner, characterized in that, It includes the following steps: S1.1: Place the tension pulley (7) between the baffle (1) and the movable plate (3). Under the pushing action of the first cylinder (2), the positioning shaft on the movable plate (3) is inserted into the positioning hole, and the positioning hole on the tension pulley (7) corresponds to the output shaft of the drive motor (5). S1.2: Start the drive motor (5). Under the action of mechanical transmission, the tension pulley (7) can be driven to rotate. At the same time, the driven pulley (8) drives the grinding wheel (10) to grind and cut the outer surface of the tension pulley (7). When cutting tension pulleys (7) of different diameters, start the second cylinder (11) to drive the height of the grinding wheel (10) to move up and down, synchronously adjust the tightness of the first conveyor belt (9) by the adjusting wheel (22), and at the same time limit and adjust the distance between the two end guide pulleys (17) according to the size of the tension pulley (7). S1.3: During the start-up process of the drive motor (5) in step S1.2, the rotation of the reciprocating lead screw (28) is driven. Under the action of screw transmission, the push rod (31) moves back and forth inside the catheter (32), and the flow rates in the first flow guiding cavity (43) and the second flow guiding cavity (44) in the spray head (37) are adaptively adjusted. Cooperating with the cleaning brush (38), the outer wall surface of the tension pulley (7) can be effectively cleaned.
