[0029] The following further elaborates on the structure of the screw disassembly and assembly device of the present utility model in conjunction with the attached drawings and specific embodiments. It can be understood that each specific embodiment does not limit the protection scope of the present utility model.
[0030] Figure 1 FIG. is a schematic structural diagram of the screw disassembly and assembly device according to an embodiment of the present utility model. Specifically, the screw disassembly and assembly device includes a driving main shaft 1, a driving gear 2, a plurality of first driven gears 3, a plurality of transmission screws 4, a plurality of second driven gears 5 and a plurality of screwdriver bits 6. The main shaft 1 is connected to the driving gear 2 and drives the driving gear 2 to rotate; the plurality of first driven gears 3 are arranged circumferentially around the driving gear 2, and the first driven gear pairs are meshed with the driving gear 3. The output shaft of each first driven gear 3 is connected to one end of one of the transmission screws 4, and the other end of the transmission screw 4 is meshed with one of the second driven gears 5; the output shaft of the second driven gear 5 is connected to one end of one of the screwdriver bits 6 and drives the screwdriver bit 6 to rotate.
[0031] When using the screw disassembly and assembly device, the positions of the plurality of screwdriver bits 6 correspond to the positions of the screws to be installed or disassembled. The number of the first driven gears 3 or the transmission screws 4 can be determined according to the number of the screws to be installed or disassembled on the target, and it needs to be greater than or equal to the number of the screws to be installed or disassembled. The working end of the screwdriver bit 6 can be of various types. For example, the screwdriver bit 6 can be an internal hexagonal socket structure, a flat head structure, a cross head structure, a multi-star structure, a star structure, a square head structure, a hexagonal structure or a Y-shaped structure, etc.
[0032] Between the driving gear 2 and the first driven gear 3, or between the other end of the transmission screw 4 and the second driven gear 5, it can be a bevel gear drive or a helical gear drive. For example, the driving gear 2 and the first driven gear 3 are bevel gears. The bevel gear can be a pitch cone, a tip cone, a root cone, a base cone, etc., and no further limitation is made here. The included angle between the axis of the driving gear 2 and the axis of the first driven gear 3 can be equal to 90° or not equal to 90°. The included angle between the axis of the driving gear 2 and the axis of the first driven gear 3 determines the power direction after the driving gear 2 is transmitted through the first driven gear 3. The transmission screw 4 is connected to the output shaft of the first driven gear 3. In practice, the two can be integrated, that is, the end of the transmission screw 4 linked to the driving gear 2 is set as a bevel gear structure. Similarly, the other end of the transmission screw 4 and the second driven gear 5 can be a helical gear. The helical gear drive is a gear drive between intersecting axes composed of two paired helical gears. By changing the helical angle direction of the two helical gears, the rotation direction of the driven wheel can be changed. The rotation direction of each screwdriver bit 6 connected to the output shaft of each second driven gear 5 can be controlled by setting the included angle between the axes of the two paired gears, the diameters of the two gear structures, the number of gears, the magnitude of the gear helix angle, etc.
[0033] Multiple first driven gears 3 can be evenly distributed around the circumference of the driving gear 2. In some embodiments, the screw disassembling and assembling device further includes a fixing ring 7 and multiple rollers (not shown in the figure). The multiple rollers are arranged in the circumferential direction of the fixing ring 7, and each transmission screw 4 passes through a roller, that is, the multiple rollers can also be evenly distributed in the circumferential direction of the fixing ring 7. Further, the fixing ring 7 can be provided with an angle scale. At this time, the multiple rollers are detachable, and the rollers can be installed at different positions according to the position of the screw and the angle scale on the fixing ring 7, or the multiple rollers can move along the circumferential direction of the fixing ring 7, and the distance between the transmission screws 4 can be adjusted by controlling the distance between the rollers.
[0034] In some embodiments, the screw disassembling and assembling device can further include a motor (not shown in the figure). The output shaft of the motor is connected to the main shaft 1 and drives the main shaft 1 to rotate, that is, the rotation of the driving gear 2 is controlled by the motor. Further, the screw disassembling and assembling device further includes a control unit 8, which is electrically connected to the motor and is used to control the rotation of the output shaft of the motor. In order to facilitate the operator to set the rotation parameters of the driving gear, such as the rotation angle, rotation speed or rotation direction, etc., the screw disassembling and assembling device can further include a user interface, which is connected to the control unit 8 and is configured to receive user control instructions.
[0035] It should be noted that in the technical solution of the screw disassembly and assembly device of the present utility model, each functional module and module unit included therein can correspond to specific hardware circuits in an integrated circuit structure. Therefore, it only involves improvements to specific hardware circuits. The hardware part is not merely a carrier for executing control software or computer programs. Thus, solving the corresponding technical problems and obtaining the corresponding technical effects do not involve the application of any control software or computer programs. That is to say, the present utility model can solve the technical problems to be solved and obtain the corresponding technical effects only by using the improvements in the hardware circuit structures involved in these modules and units, without the need to be assisted by specific control software or computer programs to achieve the corresponding functions.
[0036] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
[0037] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
