Description

Technical Field

[0001] This utility model relates to the field of bearing handling, specifically to a clamping device for bearing handling. Background Technology

[0002] Large bearings can be moved manually or mechanically. There are many types of machinery used for this purpose. Among them, hoisting machinery requires the use of clamping devices to limit the movement of large bearings. The clamping devices are used in conjunction with slings and cranes for moving. The clamping method affects the efficiency of moving large bearings, and the complex clamping operation also increases the workload of the staff.

[0003] Chinese patent CN220283332U discloses a large motor bearing handling fixture, including two semi-clamping frames. The two semi-clamping frames are symmetrically arranged and detachably connected, and can be combined to form a ring-shaped clamping frame. Each semi-clamping frame includes a frame and a base plate. The base plate is fixed to the bottom of the frame, and the top of the frame is provided with several detachably connected baffles. Several lifting rings are provided on the outward side of the frame. This bearing handling fixture can first clamp the bearing, and then cooperate with KBK to transport the bearing. The bearing can be effectively protected during the transportation process. Compared with existing manual handling, it can effectively reduce the labor intensity and improve production efficiency.

[0004] The aforementioned patent uses bolts and nuts to fix two sets of frame frames to the outside of the bearing, thereby clamping the bearing. However, since bearings come in various types and sizes, this clamping method cannot adjust the size of the clamping inner diameter according to changes in bearing size. It is not suitable for effectively clamping various types of bearings, and its application is relatively limited. Utility Model Content

[0005] To address the aforementioned issues, a clamping device for bearing handling is provided. By adjusting the components, the overall length of the clamping steel bar wrapped around the bearing can be adjusted according to changes in bearing size. This makes it suitable for effectively clamping bearings of various sizes, solving the problem that some clamping devices cannot adjust the clamping inner diameter according to changes in bearing size, thus limiting their application to various types of bearings.

[0006] To address the problems of existing technologies, this utility model provides a clamping device for bearing handling, comprising two sets of fixing rings. A guide channel is provided inside each fixing ring, and a clamping steel bar is slidably connected to the fixing ring along the guide channel. A positioning cylinder is fixedly installed in each fixing ring, limiting the clamping steel bar to its side. A fixing post is installed on each fixing ring, and an adjustment channel for receiving the clamping steel bar is provided in the fixing post. An adjustment component is provided on the fixing post to adjust the inner diameter of the clamping steel bar according to the bearing diameter.

[0007] Preferably, the adjustment assembly includes a handle knob rotatably mounted on a fixed column, a threaded rod axially fixedly connected to the handle knob, the threaded rod passing through the fixed column and rotatably mounted in a fixed ring, a movable frame threadedly connected to the threaded rod, the movable frame slidably mounted in the adjustment channel, and the movable frame fixedly connected to one end of the clamping steel bar; the fixed column is provided with a transmission assembly that constrains the movement of the clamping steel bar and prevents it from jamming.

[0008] Preferably, the transmission assembly includes a strip groove formed on the clamping steel bar, a flexible rack fixedly installed in the strip groove, and multiple large gears meshing at equal intervals next to the flexible rack, the large gears being rotatably mounted in a fixed column.

[0009] Preferably, the large gears are meshed with small gears, and two slide bars are symmetrically fixed about their own axis in the fixed column. Sliding seats are slidably mounted on the slide bars, and two movable racks are symmetrically fixed about the threaded rod on the sliding seats. The movable racks are meshed with the large gears.

[0010] Preferably, the movable frame has two grooves symmetrically formed about the threaded rod, and the positions of the grooves correspond to the positions of the large gear.

[0011] Preferably, the fixed column is equipped with a measuring component for measuring the displacement of the clamping steel bar.

[0012] Preferably, the metering component includes a groove formed on a fixed column, a sliding column slidably connected in the groove, the sliding column being fixedly connected to a sliding seat inside the upper part of the fixed column, and a metering ring being fixedly installed on the sliding column; a metering strip is fixed to the outer wall of the fixed column, and the metering ring is engaged with the outside of the fixed column and in contact with the metering strip.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. This utility model is equipped with an adjustment component that can adjust the length of the clamping steel bar that is clamped and wrapped around the outside of the bearing. Depending on the size of the bearing to be transported, the adjustment component controls the movement of the clamping steel bar in the fixed column and fixed ring, and adjusts the length of the clamping steel bar between the two sets of fixed rings, so that the clamping steel bar can clamp bearings of various sizes, thus expanding its application range.

[0015] 2. The present invention includes a transmission component that maintains the flexibility of adjusting the clamping steel bar. The clamping steel bar can be wrapped around the outside of the bearing, which is a relatively flexible structure. When it is adjusted by connecting the fixed ring and the fixed column, the transmission component helps to prevent the clamping steel bar from moving and getting stuck in the fixed ring and the fixed column, thus maintaining the flexibility of adjustment.

[0016] 3. The present invention is equipped with a metering component that can accurately measure the length of the clamping steel bar. When adjusting the clamping length of the clamping steel bar, the metering ring in the metering component moves at the same displacement as the clamping steel bar. By moving the metering ring to the position corresponding to the metering bar, the length of the clamping steel bar can be accurately measured, thereby enabling the measurement of the external dimensions of the bearing.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figures 1-4 As shown, a clamping device for bearing handling includes two sets of fixing rings 11. The fixing rings 11 have guide channels 12 inside. A clamping steel bar 14 is slidably connected in the fixing rings 11 along the direction of the guide channels 12. A positioning cylinder 13 is fixedly installed in the fixing rings 11, and the positioning cylinder 13 is limited to the side of the clamping steel bar 14. A fixing post 21 is installed on the fixing rings 11. The fixing post 21 has an adjustment channel 22 for receiving the clamping steel bar 14. The fixing post 21 is provided with an adjustment component 23 for adjusting the clamping inner diameter of the clamping steel bar 14 according to the bearing diameter.

[0029] The clamping steel bar 14 is fitted onto the outside of the bearing. According to the size of the bearing, the length of the clamping steel bar 14 between the two sets of fixing rings 11 is adjusted by adjusting component 23. The clamping steel bar 14 slides and moves in the guide channel 12 in the fixing ring 11. The guide channel 12 and the positioning cylinder 13 can constrain the movement direction of the clamping steel bar 14, so that it moves and adjusts according to the set trajectory, so that the clamping steel bar 14 wraps around and clamps the outside of the bearing, quickly achieving clamping of the outside of the bearing. The lifting strap on the crane is fixedly connected to the fixing ring 11, and the bearing is moved and transported by the crane.

[0030] See Figures 1-6 As shown, the adjustment assembly 23 includes a handle knob 231 rotatably mounted on the fixed column 21. A threaded rod 232 is axially fixedly connected to the handle knob 231. The threaded rod 232 passes through the fixed column 21 and is rotatably mounted in the fixed ring 11. A movable frame 233 is threadedly connected to the threaded rod 232. The movable frame 233 is slidably mounted in the adjustment channel 22 and is fixedly connected to one end of the clamping steel bar 14. The fixed column 21 is provided with a transmission assembly 3 that constrains the movement of the clamping steel bar 14 and prevents it from jamming.

[0031] When the handle knob 231 is turned, it drives the threaded rod 232 to rotate synchronously. The movable frame 233, which is threaded outside the threaded rod 232, is driven by the thread and moves in the fixed column 21 along the direction of the adjustment channel 22. The movement of the movable frame 233 drives the clamping steel bar 14 to move synchronously, thereby adjusting the clamping length of the clamping steel bar 14.

[0032] See Figures 2-7 As shown, the transmission assembly 3 includes a strip groove 31 formed on the clamping steel bar 14, a flexible rack 32 fixedly installed in the strip groove 31, and multiple large gears 33 meshing with each other at equal intervals next to the flexible rack 32. The large gears 33 are rotatably installed in the fixed column 21.

[0033] When the clamping steel bar 14 moves, the flexible rack 32 fixed on the clamping steel bar 14 moves synchronously. The flexible rack 32 meshes with the large gear 33, and drives the large gear 33 to rotate under the meshing transmission. The gear transmission can keep the clamping steel bar 14 moving stably in the adjustment channel 22 and the guide channel 12, and avoid the phenomenon of jamming during the movement and adjustment of the clamping steel bar 14.

[0034] See Figures 4-7 As shown, a small gear 34 is meshed between the large gears 33. Two slide bars 35 are symmetrically fixed about their own axis in the fixed column 21. A sliding seat 36 is slidably mounted on the slide bar 35. Two movable racks 37 are symmetrically fixed about the threaded rod 232 on the sliding seat 36. The movable racks 37 are meshed with the large gears 33.

[0035] When the large gear 33 rotates, the small gears 34 between adjacent large gears 33 rotate synchronously. Under the meshing transmission of the small gears 34, only the large gear 33 closest to the fixed ring 11 keeps rotating, thus keeping the entire row of large gears 33 and small gears 34 rotating. The length of the moving rack 37 is greater than the center distance between two adjacent large gears 33. Therefore, when the large gear 33 rotates, the large gear 33 pushes the sliding seat 36 to slide on the slide bar 35 through the meshing transmission with the moving rack 37. The sliding seat 36 moves in the opposite direction to the clamping steel bar 14, and the displacement of the two is the same.

[0036] See Figure 5 and Figure 6 As shown, two grooves 4 are symmetrically formed on the movable frame 233 about the threaded rod 232, and the positions of the grooves 4 correspond to the positions of the large gear 33.

[0037] When the moving frame 233 moves along the adjustment channel 22, the grooves 4 opened on the upper and lower parts of the moving frame 233 avoid the large gear 33, the small gear 34, the slide bar 35 and the slide seat 36, so as to keep the moving frame 233 moving smoothly in the adjustment channel 22.

[0038] See Figure 2 , Figure 7 and Figure 8 As shown, the fixed column 21 is equipped with a measuring component 5 for measuring the displacement of the clamping steel bar 14.

[0039] When the clamping steel bar 14 moves in the adjustment channel 22, the displacement of the clamping steel bar 14 can be detected by the metering component 5 in order to detect the size of the bearing.

[0040] See Figure 2 , Figure 7 and Figure 8As shown, the metering component 5 includes a groove 51 formed on the fixed column 21, a sliding column 52 slidably connected in the groove 51, the sliding column 52 being fixedly connected to the sliding seat 36 on the upper part of the fixed column 21, and a metering ring 53 being fixedly installed on the sliding column 52; a metering strip 54 is fixed on the outer wall of the fixed column 21, and the metering ring 53 is engaged with the outside of the fixed column 21 and in contact with the metering strip 54.

[0041] When the sliding seat 36 slides along the direction of the slide bar 35, the sliding seat 36 above the fixed column 21 drives the slide bar 52 to slide and move in the slide groove 51. The slide bar 52 and the metering ring 53 are fixed to each other and drive them to move synchronously. The metering ring 53 is engaged with the outside of the fixed column 21 and moves. The lower side of the metering ring 53 contacts the metering bar 54. According to the position where the metering ring 53 stops on the metering bar 54, the adjustment position of the clamping steel bar 14 can be detected, thereby determining the size of the bearing.

[0042] Working principle: The clamping steel bar 14 is sleeved on the outside of the bearing. The control handle knob 231 is rotated, and the handle knob 231 drives the threaded rod 232 to rotate synchronously. Under the action of thread transmission, the moving frame 233 is pushed to move in the adjustment channel 22. The moving frame 233 drives the clamping steel bar 14 to slide in the adjustment channel 22 and the guide channel 12, so as to achieve the purpose of adjusting the clamping steel bar 14 between the two sets of fixed rings 11, thereby making the clamping steel bar 14 wrap around and clamp the outside of the bearing.

[0043] When the clamping steel bar 14 moves, it drives the flexible rack 32 to move synchronously. The flexible rack 32 drives the large gear 33 to rotate through meshing transmission. The other side of the large gear 33 is meshed with the moving rack 37, controlling the moving rack 37 to move in the opposite direction and with the same displacement as the clamping steel bar 14, so that the sliding seat 36 slides on the slide bar 35. With this part of the structure, the clamping steel bar 14 is kept stable in the adjustment channel 22 and the guide channel 12, avoiding jamming during its movement and adjustment.

[0044] When the sliding seat 36 above the adjustment channel 22 moves, it drives the sliding column 52 to slide in the sliding groove 51. The sliding column 52 controls the metering ring 53 to move and engage with the fixed column 21. Based on the position of the metering ring 53 on the metering bar 54, the size of the clamping steel bar 14 is detected, thereby determining the size of the bearing.

[0045] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
