Description

Technical Field

[0001] This utility model relates to the field of workpiece assembly equipment, and specifically to a floating installation mechanism. Background Technology

[0002] In the field of automated assembly, especially when assembling workpieces with worm gears (such as worm motors and transmission components) with products having matching threaded holes, there is an angular misalignment between the workpiece's threaded threads and the product's threaded holes. If pressure is applied directly during assembly under these misalignments, the tooth tip or flank of the worm thread will rigidly collide and rub against the thread wall of the threaded hole, easily causing damage to the worm thread surface and even rendering the threaded hole or workpiece unusable. Traditional assembly structures lack the ability to automatically compensate for minute angular misalignments. Although operators can manually fine-tune them through visual observation, this results in low production efficiency and poor assembly consistency. Utility Model Content

Detailed Implementation

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 5 As shown, the floating mounting mechanism of this utility model includes: a main body 1, with a calibration plane 11 on its side; a clamping part 2, which is rotatably connected to the lower end of the main body 1 and can rotate circumferentially relative to the main body 1 around a rotation axis, the clamping part 2 being provided with a clamping structure 21 for gripping the workpiece 7; and a floating adjustment structure, including at least a side plate 31 disposed on the side of the clamping part 2 and rotating synchronously with the clamping part 2, and a first abutting member 32 and a second abutting member 33 symmetrically disposed on both sides of the side plate 31 along the length direction with the rotation axis as the center, wherein the ends of the first abutting member 32 and the second abutting member 33 are elastically abutted against the calibration plane 11 of the main body 1, and the elastic abutting force restricts the circumferential rotation angle of the side plate 31 and the clamping part 2 relative to the main body 1.

[0024] It is understandable that when assembling the workpiece 7 with the worm 71 and the product, because the worm 71 has threads on its surface, when the worm 71 of the workpiece 7 is inserted into the screw hole of the product, there will be a misalignment between the threads on the surface of the worm 71 and the screw hole of the product. If assembly is carried out directly, the worm 71 of the workpiece 7 will be damaged.

[0025] To address the aforementioned technical problems, this application proposes a floating mounting mechanism, comprising at least a main body 1, a clamping part 2, and a floating adjustment structure. This mechanism controls the partial circumferential rotation of the workpiece 7 during assembly with the product, ensuring that the thread of the worm 71 of the workpiece 7 aligns with the threaded hole of the product, thus reducing damage to the worm 71 during assembly. The main body 1 is connected to a robotic arm, and the clamping part 2 is rotatably mounted on the lower end of the main body 1 about a rotation axis. The clamping part 2 is equipped with a clamping structure 2 for clamping the workpiece 7. 1. The floating adjustment structure includes at least a side plate 31, a first abutment 32 and a second abutment 33. The side plate 31 is fixedly installed on the side of the clamping part 2 and the upper end of the side plate 31 extends to the area where the calibration plane 11 of the main body part 1 is located. The first abutment 32 and the second abutment 33 are respectively installed on both sides of the side plate 31 along the length direction of the side plate 31. The first abutment 32 and the second abutment 33 are symmetrical about the rotation axis. One end of the first abutment 32 and the second abutment 33 are elastically pressed against the calibration plane 11 of the main body part 1.

[0026] In the initial state, thanks to the synergistic effect of the first clamping member 32 and the second clamping member 33 both elastically pressing against the calibration plane 11 of the main body 1, the calibration plane 11 of the main body 1 is made parallel to the side plate 31.

[0027] When it is necessary to install the workpiece 7 with the worm gear 71 into the workpiece 7, the floating mounting mechanism of this application is first controlled by a robot to move above the workpiece 7, and the clamping part 2 is used to clamp the workpiece 7. Then, the robot places the floating mounting mechanism and the worm gear 71 of the workpiece 7 it holds into the screw hole of the product. When there is a misalignment between the thread of the worm gear 71 of the workpiece 7 and the screw hole of the product, the thread of the worm gear 71 will rotate circumferentially to match the screw hole of the product by means of the downward pressure of the floating mounting mechanism. It can be understood that when the workpiece 7 with the worm gear 71 rotates clockwise or counterclockwise, the clamping part 2 and the floating mounting mechanism will rotate clockwise or counterclockwise simultaneously. Rotation further presses the first clamping member 32 against the calibration plane 11 and reduces the elastic clamping force of the second clamping member 33 against the calibration plane 11, or reduces the elastic clamping force of the first clamping member 32 against the calibration plane 11 and further increases the elastic clamping force of the second clamping member 33 against the calibration plane 11; after the workpiece 7 is installed, under the action of the first clamping member 32 and the second clamping member 33, the calibration plane 11 of the main body 1 is parallel to the side plate 31; through this arrangement, the installation efficiency of the workpiece 7 with the worm gear 71 can be improved, while the damage to the surface of the worm gear 71 of the workpiece 7 can be reduced, thereby improving the production quality of the product.

[0028] In one or more embodiments, both the first clamping member 32 and the second clamping member 33 include: a plunger 341, which is a hollow structure and has a through hole at one end near the calibration plane 11; a ball 342, which is disposed inside the plunger 341 and can at least partially extend out of the through hole; and an elastic member, which is disposed inside the plunger 341 and is used to elastically press the ball 342 against the through hole along the axial direction of the plunger 341; the elastic member is a spring or an elastic rubber bladder.

[0029] See Figures 2 to 5 The first abutment 32 and the second abutment 33 have the same structure. The first abutment 32 and the second abutment 33 are respectively installed on both sides of the side plate 31 along the length direction of the side plate 31. The following description only uses the structure of the first abutment 32 as an example: The first abutment 32 includes a plunger 341, a ball 342 and an elastic member. The plunger 341 has a hollow structure. The plunger 341 has a through hole at one end near the calibration plane 11. The ball 342 and the elastic member are both installed in the plunger 341. The ball 342 is pushed against the through hole of the plunger 341 by the elastic member and partially extends out of the through hole. It can be understood that the inner diameter of the through hole is smaller than the outer diameter of the ball 342, so that the ball 342 can only partially extend out of the through hole and will not detach from the plunger 341.

[0030] Specifically, when the clamping part and the side plate 31 rotate clockwise relative to the main body 1 around the rotation axis, the side plate 31 can drive the first abutting member 32 to further abut against the calibration plane 11 of the main body 1, and cause the second abutting member 33 to relax its abutting force against the calibration plane 11 of the main body 1. At this time, the ball 342 of the first abutting member 32 is pressed to compress the elastic member, so that the side plate 31 and the clamping part can smoothly rotate around the main body 1, realizing the floating adjustment of the workpiece 7 installation. It can be understood that when the clamping part and the side plate 31 rotate counterclockwise relative to the main body 1 around the rotation axis, the working state of the first abutting member 32 and the second abutting member 33 is opposite to the working state described above.

[0031] In one or more embodiments, both the first abutment 32 and the second abutment 33 are threadedly mounted on the side plate 31. See also Figure 2 , Figure 4 With this setting, the distance between the ball 342 of the first abutment 32 and the second abutment 33 and the calibration plane 11 of the main body 1 can be adjusted to meet the usage requirements of different situations.

[0032] In one or more embodiments, the positions of the first abutment 32 and the second abutment 33 on the side plate 31 are adjustable along the length of the side plate 31. See also Figure 2 , Figure 4Along the length of the side plate 31, a plurality of mounting screw holes are provided on the side plate 31. The first clamping member 32 and the second clamping member 33 can be selectively configured in the mounting screw holes to achieve adjustable position on the side plate 31. With this arrangement, the clamping force of the first clamping member 32 and the second clamping member 33 on the calibration plane 11 of the main body 1 can be further adjusted.

[0033] In one or more embodiments, the clamping part 2 further includes a carrier plate 22, a clamping structure 21 is installed on the bottom of the carrier plate 22 and is rotatably connected to the main body 1 by means of the carrier plate 22, the clamping structure 21 is a gripper cylinder, and a side plate 31 is fixedly disposed on the side of the carrier plate 22; the carrier plate 22 is provided with a central shaft 41 coaxial with the rotation axis, the carrier plate 22 and the central shaft 41 rotate synchronously, and the main body 1 is connected to the central shaft 41 through a bearing 42.

[0034] See Figures 2 to 5 The clamping structure 21 is fixed to the bottom of the carrier plate 22, and the top of the carrier plate 22 is fixed with a central shaft 41 coaxial with the rotation axis by bolts. The main body 1 is connected to the central shaft 41 by means of a bearing 42. With this arrangement, the frictional force generated when the clamping structure 21 and the carrier plate 22 rotate relative to the main body 1 can be reduced, and the wear between the worm gear 71 of the workpiece 7 and the screw hole of the product can be reduced.

[0035] In one or more embodiments, a first infrared sensor 5 is installed on the main body 1 to detect whether the clamping structure 21 has deflected relative to the main body 1; a second infrared sensor 6 is installed on the side plate 31 and / or the clamping structure 21 to detect whether the clamping structure 21 has clamped the workpiece 7 in place. See also Figures 2 to 5 When the clamping structure 21 of the first infrared sensor 5 deflects circumferentially to a predetermined angle relative to the main body 1, it can be determined that the worm 71 of the workpiece 7 has been partially screwed into the screw hole of the product. At this time, the clamping structure 21 can be released from clamping the workpiece 7. The second infrared sensor 6 is used to determine whether the clamping structure 21 clamps the workpiece 7.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
