Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and in particular to a maintenance fixture and maintenance platform. Background Technology

[0002] A maintenance platform is an integrated workbench specifically designed for mechanical maintenance. Many mechanical parts require inspection and repair after prolonged use, thus necessitating a maintenance platform.

[0003] Chinese Patent No. CN221985043U discloses a medical device repair fixture and repair platform, including a repair frame. The top of the repair frame has a movable groove, and two bolts are fixedly connected between the two sides of the movable groove. Repair moving rods are fixedly connected to both ends of the repair frame. A connecting steel pipe is fixedly connected to the bottom end of each of the two moving rods, and a threaded cylinder is fixedly connected to the bottom end of each of the two connecting steel pipes. A threaded rod is threadedly connected to the inner wall of each of the two threaded cylinders, and a motor is fixedly connected to one end of each of the two threaded rods. A support column is fixedly connected to the top of each of the two fixed platforms, and a movable groove is opened on one side of each of the two support columns. A fixture repair device is provided at the bottom of the repair frame. This technical solution has a compact and reasonable structural design, solving the problem of the single structure of existing medical device repair fixtures, thereby improving the work efficiency of medical device repair.

[0004] However, the above technical solution has the following shortcomings: different objects often have multiple inspection points in different directions, and these inspection points can only fix the objects in the air for clamping and maintenance. They cannot adjust the direction and angle of the objects, and the maintenance personnel need to move with the inspection points, which reduces the practicality of the maintenance platform. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a maintenance fixture and maintenance platform that uses a self-rotating distributed chuck to synchronously rotate the object, and then the main clamping cylinder pushes the object to abut against the secondary clamping cylinder, thereby allowing the object to rotate along another axis and moving the inspection points of the object in different directions to the same side.

[0006] On one hand, this utility model proposes a maintenance clamp, including: an intermediate clamping assembly, which includes a motor a, a gear disposed at the output end of the motor a, a rack a meshing with the gear a, a lifting cylinder disposed on the rack a, a motor b disposed on the lifting cylinder, and a distributed chuck disposed at the output end of the motor b; and a two-end clamping assembly, which includes a main side frame and a secondary side frame respectively disposed on both sides of the distributed chuck, an electric cylinder a disposed on the main side frame, a main clamping cylinder rotatably disposed at the output end of the electric cylinder a, a secondary clamping cylinder rotatably disposed on the secondary side frame, and a gear b rotatably disposed on the secondary side frame; the secondary clamping cylinder has a gear ring portion, and the gear b meshes with the gear ring portion.

[0007] Preferably, the distributed chuck includes a chuck body disposed at the output end of motor b, multiple sets of clamping components disposed in a ring along the chuck body, and a protrusion disposed at the top of the chuck body.

[0008] Preferably, the clamping assembly includes an electric cylinder b disposed on the chuck body, a sliding block disposed at the output end of the electric cylinder b, a lifting plate slidably disposed on the sliding block, a transmission component damped and rotatably disposed on the sliding block, and a rack b disposed on the chuck body; the rack b is sequentially meshed with the transmission component and the lifting plate.

[0009] Preferably, the transmission component includes a gear section and a sector tooth section connected to each other, the gear section being meshed with the lifting plate, and the sector tooth section being meshed with the rack b.

[0010] Preferably, both the main clamping cylinder and the auxiliary clamping cylinder have serrated patterns.

[0011] On the other hand, this utility model also proposes a maintenance platform, which includes the aforementioned maintenance fixture, and further includes: a frame on which maintenance components are provided, a middle clamping component and two side clamping components are both provided on the frame, a lifting cylinder is slidably connected to the frame, and a main side frame and a secondary side frame are both distributed at the top of the frame.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: In use, the object to be repaired is placed on the distributed chuck, which clamps and fixes the object. Motor b drives the distributed chuck to rotate, allowing the object to adjust its orientation, thus reducing the difficulty of maintenance. Then, motor a drives the lifting cylinder to rise through gear transmission. Electric cylinder a then drives the main clamping cylinder to push the object against the secondary clamping cylinder, thus clamping and fixing the object at two points through the main and secondary clamping cylinders. Motor c drives the secondary clamping cylinder to rotate through gear transmission, which in turn rotates the object, thus avoiding blind spots in the repair process. Attached Figure Description

[0014] Example 1; as Figures 1-4 As shown, the maintenance platform proposed in this embodiment includes a frame 1, an intermediate clamping assembly 3, and two end clamping assemblies. The intermediate clamping assembly 3 includes a motor a31 mounted on the frame 1, a gear a32 mounted on the output end of the motor a31, a lifting cylinder 33 slidably mounted on the frame 1, a rack a34 mounted on the lifting cylinder 33 and meshing with the gear a32, a motor b35 mounted on the lifting cylinder 33, and a distributed chuck 36 mounted on the output end of the motor b35.

[0015] The clamping assembly at both ends includes a main side frame 4 and a secondary side frame 7 mounted opposite each other on the frame 1, an electric cylinder a5 mounted on the main side frame 4, a main clamping cylinder 6 rotatably mounted on the output end of the electric cylinder a5, a secondary clamping cylinder 8 rotatably mounted on the secondary side frame 7, and a gear b9 rotatably mounted on the secondary side frame 7; the main side frame 4 and the secondary side frame 7 are distributed on both sides of the intermediate clamping assembly 3, the secondary clamping cylinder 8 has a gear ring portion, the gear b9 meshes with the gear ring portion, the gear b9 is connected to a motor c, and a maintenance assembly 2 is mounted on the frame 1.

[0016] The maintenance component 2 can adopt a robotic arm structure of type ABB IRB 1200 or similar, or the maintenance component 2 can include a frame set at the top of the frame 1, and maintenance tools (such as electric drills) placed on the frame.

[0017] In this embodiment, the object to be repaired is placed on the distributed chuck 36, which clamps and fixes the object. Motor b35 drives the distributed chuck 36 to rotate, thereby adjusting the object's orientation and reducing the difficulty of maintenance. Then, motor a31 drives the lifting cylinder 33 to rise through gear transmission. Then, electric cylinder a5 drives the main clamping cylinder 6 to push the object to abut against the auxiliary clamping cylinder 8, thereby clamping and fixing the object at two points through the main clamping cylinder 6 and the auxiliary clamping cylinder 8. Motor c drives the auxiliary clamping cylinder 8 to rotate through gear transmission, and the auxiliary clamping cylinder 8 drives the object to rotate, thereby avoiding blind spots in the repair of the object.

[0018] Example 2; as Figure 1 , Figure 2 and Figure 4 As shown, the maintenance platform proposed in this embodiment, compared with the first embodiment, includes a distributed chuck 36 comprising a chuck body 361 disposed at the output end of the motor b35, multiple sets of clamping components disposed in a ring on the chuck body 361, and a protrusion block disposed at the top of the chuck body 361. The object is placed on the protrusion block, and the multiple clamping components fix multiple points of the object.

[0019] The clamping assembly includes an electric cylinder b362 mounted on the chuck body 361, a sliding block 363 mounted on the output end of the electric cylinder b362, a lifting plate 364 slidably mounted on the sliding block 363, a transmission component 365 damped and rotated on the sliding block 363, and a rack b366 mounted on the chuck body 361. The rack b366 is sequentially meshed with the transmission component 365 and the lifting plate 364. The electric cylinder a5, multiple electric cylinders b362, motor a31, and motor b35 are all electrically connected to a PLC control panel, thereby controlling the above structure through a pre-set program. Slip rings are provided on the chuck body 361 and the lifting cylinder 33, so that current and signals are transmitted to multiple electric cylinders b362 through the slip rings.

[0020] According to the outline of the object, the electric cylinder b362 drives the sliding block 363 to move toward the object. The lifting plate 364 on the sliding block 363 clamps the object. When the lifting plate 364 needs to release the object from the clamping state, the electric cylinder b362 drives the sliding block 363 to move away from the object until the transmission component 365 on the sliding block 363 meshes with the rack b366 and rotates. The transmission component 365 meshes and drives the lifting plate 364 to descend, so that the horizontal height of the top of the lifting plate 364 is lower than the horizontal height of the top of the sliding block 363, thereby preventing the lifting plate 364 from affecting the sliding of the object on the protrusion.

[0021] Example 3; as Figure 1 , Figure 3 and Figure 4As shown, the maintenance platform proposed in this embodiment, compared with the first embodiment, in this embodiment, the transmission component 365 includes a gear part and a sector tooth part connected to each other. The gear part is meshed with the lifting plate 364, and the sector tooth part is meshed with the rack b366. The gear part is in the shape of an incomplete gear, and the meshing teeth of the gear part are distributed above the sector tooth part. Both the main clamping cylinder 6 and the auxiliary clamping cylinder 8 have serrated patterns. The serrated patterns increase the friction between the object and the main clamping cylinder 6 and the auxiliary clamping cylinder 8.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
