Description

TECHNICAL FIELD

[0002] In material conveying, the hoisting and conveying of materials can be completed by various mechanical equipment. In this process, after the material is clamped by a mechanical hand or a boom and the like clamping assembly, the overall steering of the clamping assembly is realized by using C shaft assembly in the horizontal direction. After the overall steering of the clamped material, the material is lowered onto a conveyor belt or a transfer trolley. Alternatively, the C shaft assembly can be arranged on a truss, and the material is lowered correspondingly after the C shaft assembly is driven by a drag chain to move to a specified position along the truss.

The C shaft assembly usually includes a main support plate, a C shaft motor and a C shaft transmission component. The C shaft motor is installed and fixed on the main support plate. The output end of the C shaft motor is connected with the C shaft transmission component, and drives the driven component in the C shaft transmission component to steer and rotate. The mechanical shaft or the boom and the like clamping assembly is arranged below the driven component and is driven by the driven component to steer synchronously.

[0004] In the existing C shaft assembly, a motor fixing plate is usually used as an intermediate structural member for positioning and fixing in the connection and fixation of the C shaft motor and the main support plate. The C shaft motor is first fixed on the motor fixing plate, and then the motor fixing plate is fixed and installed with the main support plate. In this positioning and fixing operation, the position of the C shaft motor is directly fixed and has no adjustable space. When the C shaft motor and the motor fixing plate, and the motor fixing plate and the main support plate are fixed twice, any one-time fixation has installation error, such as screw not locked in place or over-tightened, which causes the installation plane to be inclined, etc. All of these can cause installation error of the C shaft motor, which can cause poor transmission cooperation between the C shaft motor and the C shaft transmission component, and there is a sticking point in transmission, thereby affecting normal steering operation.

Therefore, the following detailed description is not in a limiting sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalents. EMBODIMENT

[0022] As Figures 1 to 3 shown in one kind of automatic centering type adjustable C-axis assembly mechanism, it is the embodiment one of the utility model. The C-axis assembly includes main support frame 5, C-axis motor 3 and C-axis transmission mechanism. C-axis motor 3 and C-axis transmission mechanism are arranged on main support frame 5.

[0023] C-axis transmission mechanism includes C-axis driven gear 4 and C-axis transmission gear 6. The inner ring of C-axis driven gear 4 has a tooth shape, and the outer periphery of C-axis transmission gear 6 is engaged with the tooth shape in the inner ring. Driving gear 13 is engaged with C-axis transmission gear 6, and C-axis transmission gear 6 is engaged with C-axis driven gear 4. The output end of C-axis motor 3 is fixed with driving gear 13, and driving gear 13 is engaged with C-axis transmission gear 6 of C-axis transmission mechanism and drives C-axis driven gear 4 to rotate. C-axis transmission mechanism is connected with a mounting bracket. The clamping assembly such as mechanical shaft or boom is arranged below the mounting bracket and rotates with the C-axis driven gear.

[0024] In the positioning installation between C-axis motor 3 and support frame, secondary positioning is needed by using motor mounting plate 14.

[0025] Specifically, the first positioning is the centering positioning between C-axis motor 3 and motor mounting plate 14, and the centering positioning is realized by conical hole 12. The motor mounting plate 14 is a flat plate structure, and the flat plate structure is provided with a conical hole 12 penetrating through it. The C-axis motor 3 has a conical surface matched with the inner wall of the conical hole 12, and after the C-axis motor 3 is matched with the conical hole 12 of the flat plate structure, it is locked with the flat plate structure by bolts.

[0026] The second positioning is between the motor mounting plate 14 and the main support frame 5. The motor mounting plate 14 is provided with mounting holes 15 at four corners respectively. The mounting holes 15 are long circular holes, the center line of the C-shaft driven gear ring 4 and the C-shaft driving gear 6 is parallel to the length direction of the long circular hole, and the main support frame 5 is provided with a positioning circular hole below the long circular hole, and the main support frame 5 is positioned and fixed by bolts and nuts screwed in the long circular hole and the positioning circular hole. The motor mounting plate 14 is adjustably connected with the main support frame 5 through the mounting holes 15. The main support frame is fixed with a reference block 1, and three threaded holes are formed in the reference block 1 parallel to the plane of the main support frame 5. An adjusting bolt 2 is threadedly connected in each threaded hole, and one side end of the adjusting bolt 2 abuts against the side surface of the motor mounting plate 14. During installation, the position of the adjusting bolt relative to the reference block 1 is adjusted by rotating the adjusting bolt 2 and abutting the side surface of the motor mounting plate 14 against the adjusting bolt, so that the position between the motor mounting plate 14 and the reference block 1 is adjusted. After the position between the motor mounting plate 14 and the main support plate is determined, the corresponding long circular hole and the positioning circular hole are positioned and locked by the bolt and the nut.

[0027] Compared with the traditional C-shaft assembly which is directly positioned and fixed by the mounting plate, when the C-shaft motor 3 is connected with the motor mounting plate 14, the C-shaft motor 3 is automatically centered through the tapered hole 12 on the motor mounting plate 14, and the position between the C-shaft motor 3 and the motor mounting plate 14 is positioned.

[0028] In actual design and assembly, in order to be more convenient for adjustment, along the length direction of the long circular hole, the reference block 1 and the adjusting bolt 2 can be designed on the two sides of the motor mounting plate 14 respectively, and the adjusting bolt 2 is clamped from both ends of the motor mounting plate 14, so as to ensure the accuracy of positioning.

[0031] The transmission gear shaft 7 and the C-shaft transmission gear 6 are connected through an angular contact bearing 11. The angular contact bearing 11 is bidirectional adjustable, and a certain inclination angle can be generated between the inner and outer rings, which is beneficial to the transmission gear shaft 7 to carry the C-shaft rotating gear to mesh with the C-shaft driven gear 4 and the driving gear 13 on the two sides respectively and to effectively and smoothly drive.

[0032] The limiting groove 8 is provided with a disc spring 10 at the corresponding length direction of the two ends respectively, one end of the elastic member is fixed with the corresponding side end face of the limiting groove 8, and the other end is a matching end 9, which is matched with the transmission gear shaft 7. In the embodiment, the side face corresponding to the transmission gear shaft 7 is a concave arc surface, which is matched with the outer circumferential surface of the transmission gear shaft 7.

[0033] In the embodiment, the elastic force of the disc spring 10 can support the transmission gear shaft 7 in both directions, and the elastic deformation of the elastic member forms a gap for adjusting the transmission gear shaft 7. On the basis of adjusting the position of the C-shaft motor 3 according to the position of the driven gear and the transmission gear, the C-shaft transmission gear 6 also has a certain force automatic balance adjustment characteristic, and the C-shaft transmission gear 6 can be effectively meshed with the driving gear 13 and the C-shaft driven gear 4 respectively, which further improves the reliability of the transmission and further reduces the possible jamming in the steering.
