Technical Field
[0001] This utility model relates to the field of end effector devices, and in particular to a structure for controlling pressing and rotation with a single motor. Background Technology
[0002] Currently, traditional control mechanisms generally use multi-motor linkage schemes to achieve rotation and pressing functions, which leads to complex mechanical structures. For example, the rotary encoder and independent pressing switch are designed separately, and the transmission gear set occupies too much space, resulting in high costs. When the equipment needs both pressing and rotation functions, it cannot be achieved by relying on a single set of equipment. Summary of the Invention
[0003] This invention aims to address the shortcomings of existing technologies by providing a structure that controls pressing and rotation with a single motor.
[0004] To achieve the above objectives, this utility model adopts the following technical solution:
[0005] A single-motor controlled pressing and rotating structure includes an integrated servo motor, an energized brake module, a gear reducer, and a drive unit. The gear reducer includes a housing, a top cover, and a gear set, with the gear set housed inside the housing. The integrated servo motor is mounted on the top cover of the gear reducer and extends into the housing to connect with the gear set. The energized brake module includes a fixed end and a moving end, with the moving end positioned above the fixed end. The fixed end is mounted on the gear reducer. The drive unit includes a lead screw, a lead screw nut, a nut telescopic rod, a fixed outer cover, a spring guide block, and an end telescopic rod. The bottom end of the lead screw is connected to the shaft of the gear set via a double-row angular contact bearing. The lead screw nut is fitted onto the outer bottom end of the lead screw, and a nut boss is provided at the lower part of the lead screw nut. The nut telescopic rod is fitted above the nut boss on the outer side of the lead screw nut, and the fixed outer cover is fitted onto the outer side of the nut telescopic rod. The fixed outer cover is connected to the moving end of the brake module. A spring guide block is connected to the top end of the lead screw, and two end telescopic rods are movably connected within the spring guide block.
[0006] The reduction ratio of the gear set is [value missing].
[0007] The brake module is fixed to the top cover by bolts.
[0008] The spring guide block is provided with two spring grooves, and a buffer spring is provided in the spring groove. The top of the buffer spring is connected to the end telescopic rod in the spring groove.
[0009] The upper part of the spring guide block is covered with a top cover, and the top cover has two holes, through which the two end telescopic rods slide.
[0010] The bottom end of the telescopic rod is connected to a limiting flange, the diameter of which is larger than the diameter of the hole on the top cover.
[0011] Both of the aforementioned end telescopic rods and the lead screw below are eccentrically configured.
[0012] A dust cover is fitted over the upper outer part of the nut telescopic rod, and a dustproof sealing ring is provided between the dust cover and the outer wall of the nut telescopic rod.
[0013] The beneficial effects of this utility model are: when the device needs both pressing and rotating functions, it can achieve this with just one set of equipment, saving costs, occupying little space, and greatly improving work efficiency. Attached Figure Description

[0019] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] A single-motor controlled pressing and rotating structure includes an integrated servo motor 1, an energized brake module 2, a gear reducer 3, and a drive unit 4. The gear reducer 3 includes a housing 32, a top cover 31, and a gear set 33, which is disposed inside the housing 32. The integrated servo motor 1 is mounted on the top cover 31 of the gear reducer 3 and extends into the housing 32 to connect with the gear set 33. The energized brake module 2 includes a brake module fixed end 22 and a brake module moving end 21, with the moving end 21 positioned above the brake module fixed end 22. The brake module fixed end 22 is mounted on the gear reducer 3. The drive unit 4 includes a lead screw. 41. Lead screw nut 42. Nut telescopic rod 43. Fixed cover 44. Spring guide block 47. And end telescopic rod 46. The bottom end of the lead screw 41 is connected to the shaft of the gear set 33 through a double row angular contact bearing 48. The lead screw nut 42 is sleeved on the outer bottom end of the lead screw 41. The lower part of the lead screw nut 42 is provided with a nut boss. The nut telescopic rod 43 is sleeved on the upper part of the nut boss on the outer side of the lead screw nut 42. The fixed cover 44 is sleeved on the outer side of the nut telescopic rod 43. The fixed cover 44 is connected to the moving end 21 of the brake module. The top end of the lead screw 41 is connected to a spring guide block 47. The two end telescopic rods 46 are telescopically connected inside the spring guide block 47.
[0022] The reduction ratio of the gear set 33 is 2.
[0023] The brake module fixing end 22 is fastened to the upper cover 31 by bolts.
[0024] The spring guide block 47 is provided with two spring grooves 471, and a buffer spring 472 is provided in the spring groove 471. The top of the buffer spring 472 is connected to the end telescopic rod 46 in the spring groove 471.
[0025] The upper part of the spring guide block 47 is covered by a top cover 473, and the top cover 473 has two holes, through which two end telescopic rods 46 slide.
[0026] The bottom end of the telescopic rod 46 is connected to a limiting flange 461, and the diameter of the limiting flange 461 is larger than the diameter of the hole on the top cover 473.
[0027] Both of the aforementioned end telescopic rods 46 and the lead screw 41 below are eccentrically arranged.
[0028] A dust cover 49 is fitted on the upper outer side of the nut telescopic rod 43 above the fixed outer cover 44, and a dustproof sealing ring 45 is provided between the dust cover 49 and the outer wall of the nut telescopic rod 43.
[0029] When this utility model is in operation, the brake module 2 is energized, locking the fixed end 22 and the moving end 21 of the brake module, preventing the moving end 21 from rotating freely. When the integrated servo motor 1 starts, it drives the lead screw 41 to rotate via the gear set 33. Due to the limitation of the fixed outer cover 44, the lead screw nut 42 can only move along the axis of the lead screw 41. The lead screw nut 42 drives the end of the nut telescopic rod 43 to move along the axis of the lead screw 41, realizing the pressing function. Each end telescopic rod 46 is equipped with a buffer spring 472. When the device button is pressed, if the device button is large enough, both end telescopic rods 46 can press the device button simultaneously. If the device button cannot guarantee that both end telescopic rods 46 can be pressed simultaneously, one end telescopic rod 46 needs to be pressed while the other end telescopic rod 46 presses against the outer shell of the device, using the internal buffer spring 472 to ensure the integrity of the outer shell of the device. When the power to the brake module 2 is de-energized, the fixed end 22 and the moving end 21 of the brake module are released from their lock-up state, allowing the moving end 21 to rotate. At this time, the lead screw 41 rotates, causing the lead screw nut 42, the fixed outer cover 44, and the moving end 21 of the brake module to rotate together. The moving end 21 of the brake module is connected to the fixed outer cover 44, thus realizing the rotation function of the end effector. The end effector module has two end telescopic rods 46, which, along with the lead screw 41 below, are eccentrically positioned. When the end effector rotates, the two end telescopic rods 46 can rotate the knob of the device.
