[0030] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] Combined with this Figures 1 to 3To describe an embodiment of a bidirectional flexible sliding mechanism. Specifically, the bidirectional flexible sliding mechanism is constructed as a split structure, which has components such as a fixed plate 200, a guide shaft 300, a floating seat 400, and a spring 500. When a collision occurs, the connecting block 600 drives the supporting block 700 and the floating seat 400 in sequence. The floating seat 400 moves along the guide shaft 300 and squeezes the compression spring 500. Through the buffering effect of the spring 500, the gear is prevented from being damaged during a collision. Springs 500 are provided on both sides of the floating seat 400. When the connecting block 600 collides in any direction along the guide shaft 300, the floating seat 400 can move along the guide shaft 300 in the opposite direction of the collision, thereby achieving the purpose of bidirectional floating and improving the flexibility and work efficiency of gear installation.

[0032] Please refer to Figures 1 to 3 , a bidirectional flexible sliding mechanism, comprising:

[0033] A bottom plate 100, a pair of symmetrically placed fixing plates 200 are slidably connected to the bottom plate 100, a plurality of symmetrically distributed guide shafts 300 are provided between the two fixing plates 200, and both ends of the guide shafts 300 are respectively fixed to the fixing plates 200 on both sides;

[0034] The floating seat 400 is located at the symmetric plane of the two fixed plates 200. The guide shafts 300 pass through the floating seat 400 and are slidably connected thereto. A pair of symmetrically placed springs 500 are sleeved on any guide shaft 300, and the two springs 500 on any guide shaft 300 are respectively located on both sides of the floating seat 400. One end of the spring 500 is fixed to the floating seat 400, and the other end of the spring 500 is fixed to the fixed plate 200 on the corresponding side.

[0035] The connecting block 600 is arranged directly above the floating seat 400. A pair of symmetrically placed supporting blocks 700 are fixed to the lower end of the connecting block 600. The supporting blocks 700 are both fixed to the floating seat 400.

[0036] A driving unit 800, which is disposed on the bottom plate 100 and connected to any fixed plate 200, and is used to drive the fixed plate 200 to move along the axis direction of the guide shaft 300;

[0037] The floating seat 400 is used to move along the guide shaft 300. The material of the floating seat 400 may be considered to use wear-resistant, corrosion-resistant materials with good self-lubricating properties, such as nylon, polytetrafluoroethylene, stainless steel, etc. The floating seat 400 may also use special coatings or treatments to enhance its surface hardness or reduce the friction coefficient, thereby improving the operating performance.

[0038] When selecting the manufacturing material of spring 500, factors such as its elastic modulus, fatigue resistance, and corrosion resistance need to be considered to ensure that it can effectively reduce shock and cushion. Usually, high-carbon steel, stainless steel, alloy steel and other materials with good elasticity and durability can be selected. These materials can provide sufficient elasticity and are not easy to deform, thereby ensuring that spring 500 can still work normally after multiple collisions.

[0039] The connection block 600 is used to connect an external device. A threaded hole or a slot may be provided on the connection block 600 to facilitate a detachable connection between the connection block 600 and the external device. The connection block 600 may be made of wood or metal.

[0040] When in use, the upper end surface of the connecting block 600 is connected to the external device, and the gear to be installed is placed on the external device; the fixed plate 200 is driven to move by the driving unit 800, and the fixed plate 200 drives the guide shaft 300, the spring 500, the floating seat 400, the support block 700 and the connecting block 600 to move, and the connecting block 600 drives the external device connected thereto to move synchronously. When the external device connected to the connecting block 600 collides with the other components, the connecting block 600 drives the support block 700 and the floating seat 400 in sequence during the collision, and the floating seat 400 moves along the guide shaft 300 and squeezes the compression spring 500. Through the buffering effect of the spring 500, the gear is prevented from being damaged during the collision. The springs 500 are arranged on both sides of the floating seat 400. When the connecting block 600 collides in any direction along the guide shaft 300, the floating seat 400 can move along the guide shaft 300 in the opposite direction of the collision to achieve the purpose of bidirectional floating. The flexibility and work efficiency of the gear installation are improved.

[0041] In order to facilitate the movement of the fixed plate 200 and improve its guidance during the movement, the driving unit 800 includes a pair of symmetrically placed bearing seats 801 fixed on the base plate 100, and the fixed plates 200 are located between the two bearing seats 801. A screw rod 802 coaxially placed with the guide shaft 300 is rotatably connected between the two bearing seats 801. A threaded sleeve 803 is sleeved on the screw rod 802, and the sleeve 803 is fixedly connected to any fixed plate 200; by rotating the screw rod 802, the screw rod 802 drives the sleeve 803 and the fixed plate 200, and the sleeve 803 will rotate with the screw rod 802 to perform threaded transmission, and the sleeve 803 drives the fixed plate 200 to move along the axial direction of the screw rod 802.

[0042] Both the fixed plate 200 and the floating seat 400 are provided with avoidance grooves for the screw rod 802 to pass through; the screw rod 802 passes through the avoidance grooves, and neither the fixed plate 200 nor the floating seat 400 contacts the screw rod 802 .

[0043] In order to prevent the sleeve 803 from rotating synchronously with the screw rod 802 during rotation and thus making it impossible to perform threaded transmission, the lower end surface of the fixed plate 200 is in contact with the upper end surface of the base plate 100; the base plate 100 limits the position of the fixed plate 200, thereby constraining and limiting the position of the sleeve 803, thereby preventing the sleeve 803 from rotating during rotation of the screw rod 802.

[0044] In order to facilitate automatic control of the rotation of the screw rod 802, the drive unit 800 also includes a motor base fixed on the base plate 100, on which a servo motor 804 is mounted. The output end of the servo motor 804 is connected to a coupling 805, and the other end of the coupling 805 is coaxially connected to either end of the screw rod 802; this facilitates automatic control of the rotation of the screw rod 802.

[0045] In order to facilitate the replacement of the spring 500 during subsequent use, the guide shaft 300 and the fixing plate 200 are both set to be detachably connected;

[0046] A plurality of blind holes 201 matching the guide shaft 300 are provided on one side of the fixing plate 200 close to the guide shaft 300. The number of blind holes 201 on any fixing plate 200 is opposite to and one-to-one corresponds to the guide shaft 300. Both ends of the guide shaft 300 are inserted into the blind holes 201 of the fixing plate 200 on the corresponding side. The fixing plates 200 on both sides are detachably connected, so as to facilitate disassembly and separation for replacement of the spring 500.

[0047] Preferably, the two ends of the spring 500 do not need to be fixedly connected to the fixed plate 200 and the floating seat 400 respectively, and the two ends of the spring 500 only need to be pressed and contacted with the fixed plate 200 and the floating seat 400 respectively, which is convenient for subsequent replacement of the spring 500.

[0048] At least one pair of circular holes coaxially arranged with the guide shaft 300 is provided on the fixing plate 200, and the number of circular holes on the two fixing plates 200 is equal and one-to-one corresponding. A coaxial threaded pin 900 is provided in each circular hole. Both ends of the threaded pin 900 pass through the fixing plates 200 on both sides respectively. A limiting disk is provided at one end of the threaded pin 900, and the diameter of the limiting disk is larger than the diameter of the circular hole. A hexagonal nut 901 with threaded connection is sleeved on the other end of the threaded pin 900. During installation, the hexagonal nut 901 is first removed from the threaded pin 900, and then the end of the threaded pin 900 away from the limiting disk is inserted into the circular hole and passes through the fixing plates 200 on both sides in turn, and then the hexagonal nut 901 is sleeved on the threaded pin 900, and the fixing plates 200 on both sides are stably connected by tightening the hexagonal nut 901.
