[0020] The following describes the technical solutions in the embodiments of the present invention clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments, and all other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without any creative work are all included in the protection scope of the present invention.

[0021] As shown in Figures 1 to 8, an elastic block position regulation mechanism 100 is provided, which is used to realize position regulation of 180-degree forward and reverse rotation, and the elastic block position regulation mechanism 100 includes a base 2, a first elastic position regulation assembly 3, a second elastic position regulation assembly 4, a rotating table 1, and a bearing 7.

[0022] The base 2 is used to mount the first elastic position control assembly 3, the second elastic position control assembly 4, the rotating table 1 and the bearing 7, and the base 2 includes a base body 21 and a through hole 22 that penetrates the base body 21.

[0023] Specifically, the base 2 further includes a first groove 23 and a second groove 24 recessed from one side of the base body 21 along the axial direction of the through hole 22 and having a circular shape, and a first guide groove 25 and a second guide groove 26 formed on one side of the base body 21. The rotating table 1 includes a rotating table body 11 and a lever 12 extending from the rotating table body 11, the rotating table body 11 passing through the through hole 22 and forming a rotational connection with the second groove 24, and the lever is disposed in the first groove 23. This allows the entire rotating table 1 to be assembled with the base 2, resulting in a smaller structure, higher rotational stability, and less installation space.

[0024] The first elastic position-regulating assembly 3 is disposed in the first guide groove 25 and includes a first elastic member 31 fixed to one side of the base 2 and extending parallel to one radial direction of the through hole 22, and a first elastic block 32 fixedly connected to one end of the first elastic member 31 adjacent to the through hole 22. The first elastic member 31 elastically adjusts the first elastic block 32 to slide back and forth within the first guide groove 25. The first elastic block 32 includes a first elastic block body 321, a first guide hole 322 recessed from one end of the first elastic block body 321 away from the through hole 22, and a first recessed structure 325 recessed from one side of the first elastic block body 321. The other end of the first elastic block body 321 adjacent to the through hole 22 forms a first sliding slope 324. The first guide hole 322 cooperates with the first elastic member 31 to provide the first elastic member 31 with an operating path and attitude control, thereby improving the elastic operating efficiency of the first elastic member 31.

[0025] The second elastic position restriction assembly 4 is provided in parallel to and spaced apart from the first elastic position restriction assembly 3. The second elastic position restriction assembly 4 includes a second elastic member 41 fixed to one side of the base 2 and extending along a direction parallel to the first elastic member 31, and a second elastic block 42 fixedly connected to one end of the second elastic member 41 adjacent to the through hole 22. The second elastic block 42 includes a second elastic block main body 421, a second guide hole 422 recessed from one end of the second elastic block main body 421 away from the through hole 22, and a second recessed structure 42 recessed from one side of the second elastic block main body 421. 25, and the other end of the second elastic block body 421 close to the through hole 22 presents a second sliding inclined surface 424, and the first concave structure 325 and the second concave structure 425 are respectively located on the side where the first elastic block body 321 and the second elastic block body 421 are close to each other and are arranged opposite each other, and the side where the first sliding inclined surface 324 and the second sliding inclined surface 424 are close to each other is closer to the through hole 22 than the side where the first sliding inclined surface 324 and the second sliding inclined surface 424 are separated from each other.

[0026] The bearing 7 is mounted in the through hole 22 and fixed to the base body 21, and the rotating table body 11 is inserted into and fixed to the bearing 7 to form a rotational connection with the base body 21. The bearing 7 can reduce friction between the rotating table 1 and the base 2, and the rotating table 1 has a better rotation effect.

[0027] The lever 12 rotates clockwise or counterclockwise to the first inclined slide surface 324 or the second inclined slide surface 424 until it presses against the first elastic block body 321 or the second elastic block body 421, whereby the lever 12 slides into the second concave structure 425 or the first concave structure 325 to regulate the engagement position. The lever 12 slides into the second concave structure 425 and the first concave structure 325 via the first inclined slide surface 324 and the second inclined slide surface 424, respectively, to achieve mutual engagement or disengagement. When rotating the turntable 1 forward, the lever 12 slides into the second concave structure 425 of the second elastic block 42 via the first inclined slide surface 324 to regulate the engagement position, and when rotating the turntable 1 reversely, the lever 12 slides into the first concave structure 325 of the first elastic block 32 via the second inclined slide surface 424 to regulate the engagement position. This allows for 180° forward and reverse rotation positioning, occupies a small overall space, and the spring can effectively limit the degree of freedom of the elastic block when in a non-operating state in a vibration environment, thereby avoiding shaking and effectively reducing noise, and providing high reliability.

[0028] In this embodiment, the first elastic member 31 further includes a first position regulating block 323 protruding and extending from the bottom side of the first elastic block body 321 adjacent to the base 2, and the second elastic member further includes a second position regulating block 423 protruding and extending from the bottom side of the second elastic block body 421 adjacent to the base 2.

[0029] The first guide groove 25 is recessed inward to form a first position restriction base 5, and the second guide groove 26 is recessed inward to form a second position restriction base 6, the first position restriction block 323 is installed in contact with the first position restriction base 5, and the second position restriction block 423 is installed in contact with the second position restriction base 6. This increases stability when the entire structure is brought into contact.

[0030] Specifically, the first guide groove 25 is recessed inward to form the first position restriction block 5, and the second guide groove 26 is recessed inward to form the second position restriction block 6, so that the first position restriction block 323 is installed in contact with the first position restriction block 5, the second position restriction block 423 is installed in contact with the second position restriction block 6, and the lever 12 slides into the second concave structure 425 and the first concave structure 325 via the first slide inclined surface 324 and the second slide inclined surface 424, respectively, to engage with or disengage from each other. The first elastic member 31 and the second elastic member 41 press the first elastic block 32 and the second elastic block 42 into the first guide groove 25 and the second guide groove 26, respectively. The first position restricting block 323 of the first elastic block 32 can contact the first position restricting base 5 to control the initial position of the first elastic block 32 in the first guide groove 25, effectively preventing the first elastic block 32 from contacting the turntable 1, causing wear and resulting in a loss of rotation efficiency. The second elastic member 41 and the second elastic member 41 press the second elastic block 42 and the second elastic block 42 into the second guide groove 26 and the second guide groove 26, respectively. The second position restricting block 423 of the second elastic block 42 can contact the second position restricting base 6 to control the initial position of the second elastic block 42 in the second guide groove 26, effectively preventing the second elastic block 42 from contacting the turntable 1.

[0031] In this embodiment, the lever 12 includes a lever body 121 that protrudes from the rotating base body 11 and a convex structure 122 that extends from one end of the lever body 121 away from the rotating base body 11 toward opposite sides and is perpendicular to the lever body 121. The convex structure 122 is pressed against the first sliding slope 324 or the second sliding slope 424 and slides to an engagement position with the second concave structure 425 or the first concave structure 325. The convex structure 122 and the first concave structure 325 or the second concave structure 425 are interlocked and locked with each other. The characteristics of the convex structure of the lever 12 and the characteristics of the concave structure of the elastic block enable them to interlock with each other during operation and disengage from each other when the operation is completed, resulting in a high positioning effect and easy operation.

[0032] In this embodiment, both ends of the convex structure are recessed to form an arcuate structure, which is used to contact the first sliding inclined surface 324 or the second sliding inclined surface 424 to convert rotational motion into linear motion.

[0033] In this embodiment, the first sliding inclined surface 324, the second sliding inclined surface 424 and the arc surface structure are all formed by a coating process surface treatment, preferably a DLC (Diamond-like Carbon) surface treatment process, which can effectively improve hardness and wear resistance, reduce the friction coefficient, improve sliding performance, and prevent jamming.

[0034] In this embodiment, the first elastic member 31 includes a first guide post 311 fixed to the base 2 and a first spring 312 fitted onto the first guide post 311 and having one end fixed to the base 2, with the other end of the first spring 312 extending and inserted into the first guide hole 322 to form a fixed connection with the first guide hole 322. By keeping the first spring 312 in a compressed state at all times, the initial position of the first elastic block 32 can be controlled, and by providing the other end of the first spring 312 in the first guide hole 322, vibration can be avoided, noise can be reduced, and the first slider can be prevented from contacting the rotating table 1 and causing wear.

[0035] In this embodiment, the second elastic member 41 includes a second guide post 411 fixed to the base 2 and a second spring 412 fitted onto the second guide post 411 and having one end fixed to the base 2, with the other end of the second spring 412 extending and inserted into the second guide hole 422 to form a fixed connection with the second guide hole 422. By keeping the second spring 412 in a compressed state at all times, the initial position of the second elastic block 42 can be controlled, and by providing the other end of the second spring 412 in the second guide hole 422, vibration can be avoided, noise can be reduced, and the second slider can be prevented from contacting the rotary table 1 and causing wear.

[0036] In this embodiment, the first guide pillar 311 and the second guide pillar 411 are both screws, which are easy to connect and disconnect.

[0037] In this embodiment, the turntable body 11 has a mesohole 13 formed therethrough, which is used to attach a wire harness. The mesohole 13 in the turntable 1 facilitates passage of the wire harness, and rotation of ±180° prevents the wire harness from being excessively twisted, providing high safety.

[0038] The operating principle of the elastic block position restriction mechanism 100 of the present invention is as follows.

[0039] The rotational demand of the robot's turntable 1 is position M → position N → position M → position K → position M. Position M is the zero point position, position N is the position where it rotates forward by 180°, and position K is the position where it rotates backward by 180°.

[0040] 1. Position M is the initial position of the robot's turntable 1, where the lever 12 of the turntable 1 is at point A, the first elastic block 32 is at point B, and the second elastic block 42 is at point C. 2. From position M to position N, during the process of the robot turntable 1 rotating forward 180°, the first elastic block 32 moves from position B to position B1 along direction D1 as shown in the figure due to the action of the lever 12, the arc surface of the lever 12 restricts the first elastic block 32 to position B1, the boss of the lever 12 engages with the recess of the second elastic block 42, the second elastic block 42 is still in position C, restricting further forward rotation of the turntable 1, and positioning the lever 12 of the turntable 1 at position A1, thereby realizing the positional restriction of the 180° forward rotation of the robot turntable 1. 3. From position N to position M, the robot turntable 1 reverses and returns to the zero point, the boss of the lever 12 disengages from the recess of the second elastic block 42 and returns from position A1 to position A, the position of the second elastic block 42 remains unchanged and remains at position C, and the first elastic block 32 slides in the opposite direction along D1 under the action of the spring and returns from B1 to position B, thereby realizing the restriction of the position of the elastic block. 4. From position M to position K, during the process of the robot turntable 1 reversing 180°, the second elastic block 42 moves from position C to position C1 along direction D2 shown in the figure under the action of the lever 12, the arc surface of the lever 12 restricts the second elastic block 42 to be at position C1, the boss of the lever 12 engages with the recess of the first elastic block 32, the first elastic block 32 is still at position B, restricts further reversal of the turntable 1, and positions the lever 12 of the turntable 1 at position A1, thereby realizing the positional restriction of the 180° reversal of the robot turntable 1. 5. From position K to position M, the robot turntable 1 rotates forward and returns to the zero point, the boss of the lever 12 disengages from the recess of the first elastic block 32 and returns from position A1 to position A, the position of the first elastic block 32 remains unchanged and is still at position B, and the second elastic block 42 slides in the opposite direction along D2 under the action of the spring and returns from position C1 to position C, thereby limiting the position of the elastic block.

[0041] Compared to the related art, the elastic block position restricting mechanism of the present invention has a through-hole in the base, a first elastic position restricting assembly and a second elastic position restricting assembly mounted on the base to restrict the rotational position of the rotating platform, the first elastic member of the first elastic position restricting assembly adjusts the second elastic block, and the second elastic member of the second elastic position restricting assembly adjusts the second elastic block so that when the rotating platform rotates forward, the lever slides through the first inclined slide surface into the second recessed structure of the second elastic block to restrict the meshing position, and when the rotating platform rotates reversely, the lever slides through the second inclined slide surface into the first recessed structure of the first elastic block to restrict the meshing position, thereby realizing 180° forward and reverse rotation restriction. The overall occupancy is small, and the spring effectively restricts the degree of freedom of the elastic block when not in operation in a vibration environment, thereby avoiding shaking and effectively reducing noise, and is highly reliable.

[0042] It should be noted that the above is merely an embodiment of the present invention, and those skilled in the art may make modifications without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
