This may easily make it difficult to quickly place the roller on the support frame, affecting work efficiency. Summary of the invention

[0005] In order to reduce the adverse effects on work efficiency, the present application provides a roller hardness detection device.

[0006] The present application provides a roller hardness detection device that adopts the following technical solution: A roller hardness detection device comprises a workbench and a support frame slidably connected to the workbench along the height direction of the workbench, the support frame corresponds to the end of the roller one-to-one, and rotating rollers rotatably connected to the workbench are provided on both sides of the support frame connection line, one side of the workbench is provided with a loading rack arranged along the height direction of the workbench, a movable plate is inserted and slidably connected to the loading rack, a flip plate is provided on the side of the movable plate away from the support frame, the roller is placed on the upper side of the movable plate and the flip plate, a fixing piece is provided between the flip plate and the movable plate, and a driving component is provided on the loading rack to drive the movable plate to move and drive the flip plate to flip the roller to between the rotating rollers.

[0007] By adopting the above technical scheme, the rolling roller is placed on the upper side of the movable plate and the flip plate. At this time, the movable plate and the flip plate are fixed by fixing parts, and the movable plate is driven by the driving component to move along the height direction of the loading rack until it moves to the upper side of the loading rack. At this time, the fixing of the movable plate and the flip plate is released, and the flip plate is driven by the driving component to rotate in the direction close to the workbench, thereby driving the rolling roller to roll onto one of the rotating rollers. At this time, the rotating roller rotates and drives the rolling roller to roll between the two rotating rollers, driving the support frame to move upward and support the rolling roller, thereby facilitating the rapid placement of the rolling roller on the support frame and reducing the adverse effects on work efficiency.

[0008] Optionally, the flip plate is inserted into the movable plate at a side close to the movable plate, and the upper side of the movable plate is flush with the upper side of the flip plate, and the fixing part includes fixing rods symmetrically arranged on both sides of the flip plate close to the movable plate, the fixing rods have a circular cross-section, and the ends of the fixing rods away from each other are fixedly connected to driving rods with a square cross-section and passing through the movable plate, and the driving rods are slidingly connected to the movable plate, and when the flip plate is fixed to the movable plate, the fixing rods are inserted into the flip plate, and the ends of the driving rods away from each other are flush with the side wall of the movable plate, and the end of the driving rod close to the fixing rod is inserted into the flip plate, and an unlocking part is provided on the upper side of the loading rack for driving the driving rod to disengage from the flip plate.

[0009] By adopting the above technical solution, when the movable plate and the flip plate are fixed, the end of the driving rod close to each other is inserted into the flip plate. At this time, the cross-sectional shape of the driving rod limits the rotation of the flip plate. When the fixation is released, the unlocking member drives the driving rod to move in the direction away from each other until the driving rod is disengaged from the flip rod, and the end of the driving rod away from each other is inserted into the loading rack. At this time, the movable plate is fixed to the loading rack, and the driving assembly continues to drive the flip plate to move. At this time, the flip plate rotates along the fixed rod in the direction close to the workbench, thereby facilitating the driving of the rolling rollers to roll between the rotating rollers, reducing the adverse effects on work efficiency.

[0010] Optionally, the driving assembly includes a driving plate located on the side of the flip plate away from the movable plate, the driving plate abutting against the lower side of the flip plate, one end of the driving plate is inserted and threadedly connected to a first lead screw rotatably connected to the loading rack, and the other end is inserted and slidably connected to a guide rod fixedly connected to the loading rack.

[0011] By adopting the above technical solution, the first screw is rotated and the driving plate is driven to push the flip plate to drive the movable plate to move upward. At this time, the guide rod guides the driving plate to reduce the possibility of the driving plate deviation. When the movable plate moves to the upper side of the loading rack and is released from the fixation with the flip plate, the driving plate continues to be driven upward, thereby pushing the flip plate to rotate along the fixed rod, which is convenient for driving the rolling roller to roll between the rotating rollers, reducing the adverse effect on work efficiency.

[0012] Optionally, the unlocking member includes a hinged rod corresponding to the driving rod one by one and hinged on the driving rod on the side close to the workbench, and the ends of the hinged rods away from the driving rods are inclined in the direction of approaching each other and are hinged with a moving block, the moving block moves in the direction approaching or away from the driving rod, and a first spring is provided between the moving block and the moving plate, and a first hydraulic cylinder facing the moving plate is provided inside the upper side of the loading rack. When the moving plate moves to be level with the upper side of the loading rack, the first hydraulic cylinder is inserted into the moving plate and is located directly above the moving block, and an unlocking block is provided on the telescopic rod of the first hydraulic cylinder, and the side of the unlocking block close to the moving block is set to an inclined surface inclined toward the side close to the driving rod and toward the side away from the moving block.

[0013] By adopting the above technical solution, when the moving plate moves to the loading rack, the first hydraulic cylinder is inserted into the moving plate. At this time, the telescopic rod of the first hydraulic cylinder is extended, and the unlocking block is squeezed by the inclined surface to move in the direction close to the driving rod, thereby driving the driving rod to move in the direction away from each other through the hinged rod until the end is inserted into the loading rack. At this time, the first spring is stretched, and the flip plate is rotated to be parallel with the moving plate. The telescopic rod of the first hydraulic cylinder contracts and drives the unlocking block to separate from the moving block. At this time, the first spring restores its deformation and drives the end of the driving rod that is close to each other to be inserted into the flip plate, thereby fixing the flip plate, making it convenient to take over the rolling roller again, thereby improving the rolling roller transportation efficiency.

[0014] Optionally, the workbench is provided with a buffer plate located between the rotating rollers and arranged along the length direction of the workbench, the upper side of the buffer plate is arranged to be an arc that is recessed downward along its own width direction, a second spring is provided between the buffer plate and the workbench, and a damping column is provided on the lower side of the buffer plate that is facing the workbench and fixedly connected to the workbench, when the second spring is at its original length, the height of the upper side of the buffer plate is higher than the height of the upper side of the rotating roller.

[0015] By adopting the above technical solution, when the roller rolls between the rotating rollers, it first contacts the buffer plate and drives the buffer plate to move toward the workbench. At this time, the damping column and the second spring are compressed, thereby buffering the roller and reducing the impact of the roller on the roller. When the roller is located between the rotating rollers and abuts against the rotating roller, the upper side of the buffer plate is lower than the upper side of the rotating roller, which makes it easier for the rotating roller to drive the roller to rotate and improves work efficiency.

[0016] Optionally, a driving motor is provided at the end of one of the rotating rollers, a connecting component is provided between the driving motor and the corresponding rotating roller to connect the two, a mounting frame is provided on the workbench, a probe facing the roller is provided on the upper side of the mounting frame, and a moving component for driving the probe to move along the length direction of the roller is provided on the mounting frame.

[0017] By adopting the above technical solution, when the rolling roller rolls between the rotating rollers, the connecting component is not connected to the driving motor and the corresponding rotating roller. The driving motor drives the corresponding rotating roller to rotate through the connecting component, thereby driving the rolling roller to rotate. The other rotating roller supports the rolling roller and rotates with the rolling roller. At this time, the moving component drives the probe to move along the length direction of the rolling roller, which is convenient for detecting the hardness of various parts of the rolling roller and improving work efficiency.

[0018] Optionally, the connecting assembly includes a gear ring located at one end of the rotating roller close to the drive motor, a first gear is meshed on one side of the gear ring, the drive motor is installed at the axis of the first gear, and a control component connecting the gear ring and the rotating roller is provided between the two.

[0019] By adopting the above technical solution, when the rotating roller rotates under the gravity of the rolling roller, the control component is not connected to the ring gear and the corresponding rotating roller. When the rolling roller is driven to rotate, the driving motor drives the ring gear to drive the ring gear to rotate. At this time, the ring gear drives the corresponding rotating roller to rotate toward the loading rack through the control component and drives the rolling roller to rotate, which makes it convenient for the probe to perform hardness detection on various locations on the outside of the rolling roller, thereby improving work efficiency.

[0020] Optionally, the control member includes a ratchet wheel coaxial with the rotating roller and fixedly connected to the end of the rotating roller, the ratchet wheel is inserted into the gear ring and coaxial with the gear ring, and a pawl engaged with the ratchet wheel is hinged on the inner side wall of the gear ring.

[0021] By adopting the above technical solution, when the rolling roller rolls onto the rotating roller and drives the rotating roller to rotate in the direction close to the support frame, the ratchet rotates relative to the ring gear. When the driving motor drives the rotating roller to rotate, the ring gear is relatively fixed to the ratchet through the pawl, so that the rotating roller is driven to rotate through the ratchet, which makes it convenient for the probe to perform hardness detection on various locations on the outside of the rolling roller, thereby improving work efficiency.

[0022] Optionally, the moving component includes a second screw arranged along the length direction of the workbench and rotatably connected to the mounting frame, a driving block threadably connected to the second screw is provided on the upper side of the probe, and a second hydraulic cylinder is provided between the driving block and the probe.

[0023] By adopting the above technical solution, when the rotating roller drives the rolling roller to rotate, the second lead screw is rotated and the driving block is driven to drive the second hydraulic cylinder and the probe to move along the length direction of the second lead screw. When the probe moves to the point to be tested, the second hydraulic cylinder drives the probe to move closer to or away from the rolling roller, which facilitates the hardness detection of the rolling roller and improves work efficiency.

[0024] Optionally, a belt connecting the first gear and the second screw is provided between the two.

[0025] By adopting the above technical solution, when the driving motor drives the first gear to drive the gear ring and the rotating roller to rotate, the belt drives the second lead screw to rotate with the first gear, which is convenient for driving the roller to rotate and driving the probe to move at the same time, thereby improving work efficiency.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: The roller is placed on the upper side of the moving plate and the turning plate, the driving component drives the moving plate to move to the upper side of the loading rack, the fixing of the moving plate and the turning plate is released, the turning plate is driven to rotate by the driving component and the roller is driven to roll onto one of the rotating rollers, at this time the rotating roller rotates and drives the roller to roll between the two rotating rollers, the supporting frame is driven to move upward and support the roller, so as to facilitate the rapid placement of the roller on the supporting frame; The ends of the driving rods that are close to each other are inserted into the flip plate. At this time, the cross-sectional shape of the driving rods restricts the rotation of the flip plate. When the fixation is released, the unlocking member drives the driving rods to move in the direction away from each other until the driving rods are separated from the flip rods, and the ends of the driving rods that are away from each other are inserted into the loading rack. At this time, the moving plate is fixed to the loading rack, and the driving assembly continues to drive the flip plate to move. At this time, the flip plate rotates along the fixed rod in the direction close to the workbench, so as to facilitate the driving roller to roll between the rotating rollers; The roller first rolls and contacts the buffer plate and drives the buffer plate to move. At this time, the damping column and the second spring are compressed, thereby buffering the roller and reducing the impact of the roller on the roller. When the roller abuts against the two rotating rollers, the upper side of the buffer plate is lower than the upper side of the rotating roller, which makes it easier for the rotating roller to drive the roller to rotate.

When the support frame 3 supports the rolls, the ends of the rolls are inserted into the corresponding support grooves 31, and the upper sides of the rotating rollers 32 are in contact with the side walls of the rolls.

[0035] Reference Figure 2 and Figure 3A vertical loading rack 4 whose upper end height is level with the upper side height of the rotating roller 32 is fixedly connected to one side of the workbench 1 in the length direction. A horizontal moving plate 41 is inserted and slidably connected in the loading rack 4. The side of the moving plate 41 away from the workbench 1 is located outside the loading rack 4, and the other three vertical side walls of the moving plate 41 are in contact with the inner side wall of the loading rack 4. A horizontal flip plate 42 is provided on the side of the moving plate 41 away from the workbench 1. A fixing groove 411 with an upward opening and a length less than the length of the moving plate 41 is provided on the upper side of the side of the moving plate 41 close to the flip plate 42. The length of the flip plate 42 close to the side of the moving plate 41 is adapted to the length of the fixing groove 411, and the side of the flip plate 42 close to the fixing groove 411 is inserted into the fixing groove 411. The side of the flip plate 42 inserted into the fixing groove 411 is provided with a chamfer.

[0036] Reference Figure 2 and Figure 4 A fixing member 5 is provided between the moving plate 41 and the flip plate 42 to connect the two. When the flip plate 42 and the moving plate 41 are fixed, the upper side of the flip plate 42 is flush with the upper side of the moving plate 41, and a driving assembly 6 is provided on the loading rack 4 to drive the moving plate 41 and the flip plate 42 to move upward and drive the flip plate 42 to flip. A vertical third hydraulic cylinder 33 is fixedly connected to the lower end of the support frame 3, and the end of the third hydraulic cylinder 33 away from the support frame 3 is fixedly connected to the workbench 1.

[0037] Reference Figure 1 and Figure 2 , a buffer plate 12 is provided between the support frame 3 and is located between the rotating rollers 32 and is arranged along the length direction of the workbench 1. The upper side of the buffer plate 12 is arranged in an arc shape that gradually sinks downward from the two sides to the middle. The four corners of the lower side of the buffer plate 12 are fixedly connected with vertical damping columns 121, and the lower end of the damping column 121 is fixedly connected to the workbench 1. The lower side of the buffer plate 12 is fixedly connected with a second spring 122 that is vertical and sleeved on the damping column 121 and corresponds to the damping column 121 one by one, and the lower end of the second spring 122 is fixedly connected to the workbench 1.

[0038] The rolling roller is placed on the upper side of the movable plate 41 and the flip plate 42. At this time, the movable plate 41 and the flip plate 42 are fixed. The movable plate 41 is driven by the driving component 6 to move along the height direction of the loading rack 4 until it moves to the upper side of the loading rack 4. The movable plate 41 and the flip plate 42 are released, and the driving component 6 drives the flip plate 42 to rotate in the direction close to the workbench 1, thereby driving the rolling roller to roll onto the rotating roller 32 close to the loading rack 4. At this time, the rotating roller 32 rotates and drives the rolling roller to roll between the two rotating rollers 32, first contacts the buffer plate 12 and drives the buffer plate 12 to move downward. At this time, the damping column 121 and the second spring 122 are compressed and buffer the rolling roller, and the third hydraulic cylinder 33 drives the support frame 3 to move upward and support the rolling roller. The upper side height of the buffer plate 12 is lower than the upper side height of the rotating roller 32, which is convenient for quickly placing the rolling roller on the support frame 3.

[0039] Reference Figure 3 and Figure 4 The fixing member 5 includes two fixing rods 51 located in the fixing groove 411 and symmetrically arranged at both ends of the flip plate 42. The fixing rods 51 are circular in cross section and face the flip plate 42. The flip plate 42 is provided with plug-in grooves 421 corresponding to the fixing rods 51. The ends of the fixing rods 51 that are away from each other are fixedly connected with driving rods 52 that are square in cross section and face the flip plate 42. The ends of the driving rods 52 that are away from each other pass through the moving plate 41 and are slidably connected to the moving plate 41. The flip plate 42 is provided with a control groove 422 that is adapted to the end of the driving rod 52 that is close to the fixing rod 51 and is connected to the corresponding plug-in groove 421. When the moving plate 41 and the flip plate 42 are fixed, the fixing rods 51 are inserted into the corresponding plug-in grooves 421, the ends of the driving rods 52 that are close to each other are inserted into the corresponding control grooves 422, and the ends of the driving rods 52 that are away from each other are flush with the side wall of the moving plate 41. The upper side of the loading rack 4 is provided with an unlocking member 7 that drives the driving rod 52 to disengage from the flip plate 42.

[0040] When the movable plate 41 and the flip plate 42 are fixed, the end of the driving rod 52 that is close to each other is inserted into the flip plate 42. At this time, the cross-sectional shape of the driving rod 52 limits the rotation of the flip plate 42. When the fixation is released, the unlocking member 7 drives the driving rod 52 to move in the direction away from each other until the driving rod 52 is separated from the flip rod and the end of the driving rod 52 that is away from each other is inserted into the loading rack 4. At this time, the movable plate 41 is fixed to the loading rack 4, and the driving assembly 6 continues to drive the flip plate 42 to move. At this time, the flip plate 42 rotates along the fixed rod 51 in the direction close to the workbench 1, so as to drive the rolling roller to roll between the rotating rollers 32.

[0041] Reference Figure 3 and Figure 4 The unlocking member 7 includes a control edge 71 fixedly connected to the upper side of the material loading rack 4 and close to the workbench 1. A mounting groove 412 adapted to the control edge 71 is provided on the upper side of the moving plate 41 and close to the workbench 1. When the moving plate 41 moves to the upper side and is flush with the upper side of the material loading rack 4, the control edge 71 is inserted into the mounting groove 412. A hinged rod 72 is hingedly connected to the side of the driving rod 52 close to the control edge 71. A cavity is provided in the moving plate 41, and the hinged rod 72 is located in the cavity. The ends of the hinged rods 72 away from the corresponding driving rods 52 are tilted in a direction close to each other and are hingedly connected to the same moving block 73.

[0042] The moving block 73 is slidably connected to the moving plate 41 in the direction of approaching or moving away from the driving rod 52. The side of the moving block 73 away from the driving rod 52 is fixedly connected to a first spring 74, and one end of the first spring 74 away from the moving block 73 is fixedly connected to the inner wall of the moving plate 41. When the first spring 74 is at its original length, the end of the driving rod 52 away from each other is flush with the side wall of the moving plate 41. A first hydraulic cylinder 75 is fixedly connected to the lower side of the control edge 71, which is vertical and directly opposite to the moving block 73. The telescopic rod of the first hydraulic cylinder 75 is downwardly and fixedly connected to an unlocking block 76, and the lower side of the unlocking block 76 is set to be an inclined surface inclined upward and close to the driving rod 52.

[0043] When the upper side of the moving plate 41 is level with the upper side of the loading rack 4, the telescopic rod of the first hydraulic cylinder 75 is inserted into the cavity, and the lower side of the unlocking block 76 contacts the moving block 73. The telescopic rod of the first hydraulic cylinder 75 is driven to extend, and at this time, the unlocking block 76 squeezes the moving block 73 through its own inclined surface to move toward the direction of approaching the driving rod 52. The hinged rod 72 moves and rotates under the drive of the moving block 73, thereby driving the driving rod 52 to move away from each other until it is out of the control groove 422, and the end of the driving rod 52 away from each other is inserted into the side wall of the loading rack 4.

[0044] The movable plate 41 moves to the upper side of the loading rack 4, and the first hydraulic cylinder 75 is inserted into the movable plate 41. The telescopic rod of the first hydraulic cylinder 75 is extended, and the unlocking block 76 squeezes the movable block 73 in the direction close to the driving rod 52 through the inclined surface, and drives the driving rod 52 to move in the direction away from each other through the hinge rod 72 until the end is inserted into the loading rack 4. At this time, the first spring 74 is stretched, and the flip plate 42 rotates to be parallel with the movable plate 41, and the telescopic rod of the first hydraulic cylinder 75 contracts. The first spring 74 restores its deformation and drives the end of the driving rod 52 that is close to each other to be inserted into the flip plate 42, thereby fixing the flip plate 42 again.

[0045] Reference Figure 2 The driving assembly 6 includes a driving plate 61 that abuts against the lower side of the flip plate 42 and away from the side of the moving plate 41. The length of the driving plate 61 is greater than the length of the flip plate 42, and one end of the driving plate 61 is plugged and threaded with a first lead screw 62 that is vertical and rotatably connected to the outer wall of the loading rack 4, and the other end of the driving plate 61 is plugged and slidably connected with a guide rod 63 that is vertically sheared and fixedly connected to the outer wall of the loading rack 4. A control motor 64 that is fixedly connected to the loading rack 4 is installed at the lower end of the first lead screw 62.

[0046] The control motor 64 causes the first screw 62 to drive the driving plate 61 to push the flip plate 42 to drive the movable plate 41 to move upward, and the guide rod 63 guides the driving plate 61. When the movable plate 41 moves to the upper side of the loading rack 4 and is released from the fixation with the flip plate 42, the driving plate 61 continues to be driven to move upward, thereby pushing the flip plate 42 to rotate along the fixed rod 51, so as to facilitate driving the rolling roller to roll between the rotating rollers 32.

[0047] Reference Figure 1 and Figure 2 , a driving motor 321 fixedly connected to the workbench 1 is provided at one end of the rotating roller 32 near the loading rack 4, and a connecting assembly 8 connecting the driving motor 321 and the corresponding rotating roller 32 is provided between the two. The connecting assembly 8 includes a gear ring 81 located at one end of the rotating roller 32 near the driving motor 321 and coaxial with the rotating roller 32, a first gear 82 is meshed on one side of the gear ring 81, the output shaft of the driving motor 321 is fixedly connected to the axis of one side of the first gear 82, and a control member 83 for controlling the connection between the gear ring 81 and the corresponding rotating roller 32 is provided between the gear ring 81 and the corresponding rotating roller 32.

[0048] The control member 83 includes a ratchet 831 fixedly connected to the end of the corresponding rotating roller 32, the ratchet 831 is inserted into the gear ring 81 and is coaxial with the gear ring 81, and a ratchet 832 meshing with the ratchet 831 is hinged on the inner wall of the gear ring 81. When the driving motor 321 drives the rotating roller 32 to rotate in a direction close to the loading rack 4, the ratchet 832 meshes with the ratchet 831, and the gear ring 81 and the ratchet 831 are relatively fixed.

[0049] When the rolling roller rolls onto the rotating roller 32 and drives the rotating roller 32 to rotate toward the support frame 3, the ratchet 831 rotates relative to the ring gear 81. When the driving motor 321 drives the rotating roller 32 to rotate through the first gear 82 and the ring gear 81, the ring gear 81 is relatively fixed to the ratchet 831 through the pawl 832, thereby driving the rotating roller 32 to rotate through the ratchet 831, making it convenient for the probe 111 to perform hardness detection on various locations on the outside of the rolling roller.

[0050] Reference Figure 1 The moving assembly 2 includes a driving block 21 located on the upper side of the probe 111, and both ends of the lower side of the driving block 21 are fixedly connected with vertical limit plates 22 located on both sides of the probe 111. The upper side of the probe 111 is fixedly connected with a limit block 23, and the sides of the limit plates 22 that are close to each other are in contact with the side walls of the limit block 23, thereby limiting the limit block 23 in the horizontal direction.
