DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a rotatable positioning device according to some embodiments of the present invention includes: a floating plate 100, a rotation positioning assembly 200 and a support frame 300; like Figure 3 As shown, the rotary positioning assembly 200 includes a rotary disk 201 and a floating disk positioning assembly 205. The rotary disk 201 is rotatably connected to the support frame 300. The floating disk positioning assembly 205 is fixedly connected to the support frame 300. The floating disk positioning assembly 205 includes a positioning sleeve 2051 and a positioning shaft 2052 slidably disposed in the positioning sleeve 2051. The floating plate 100 is fixedly connected to the rotating plate 201. The rotation of the rotating plate 201 drives the rotation of the floating plate 100, thereby realizing the rotation of the parts to be assembled on the floating plate 100. like Figure 2 As shown, the floating plate 100 is provided with a plurality of rotation positioning holes 103, and the rotation positioning holes 103 match the positioning shaft 2052 to achieve the fixation and positioning of the floating plate 100, and further achieve the positioning of the accessories to be assembled on the floating plate 100; The floating plate 100 is used to fix the parts to be assembled, such as chassis-related sub-assemblies or assemblies (such as the front suspension, rear suspension, motor, generator, transformer, powertrain, etc.).

[0021] like Figure 4 As shown, in certain embodiments of the present invention, a plurality of first limiting shafts 20521 are provided on the positioning shaft 2052, and a first slide rail 20511 matching the first limiting shaft 20521 is provided on the positioning sleeve 2051. The sliding of the first limiting shaft 20521 on the first slide rail 20511 enables the positioning shaft 2052 to slide in the positioning sleeve 2051. The combination of the first limiting shaft 20521 and the first slide rail 20511 simultaneously limits the up and down movement position of the positioning shaft 2052.

[0022] In certain embodiments of the present invention, the floating plate positioning assembly 205 further includes several groups of control assemblies, each of which includes a pressure rod 203 and a support seat 204. The pressure rod 203 is mounted on the first limiting shaft 20521, one end of the pressure rod 203 is rotatably connected to the support frame 300, and the other end of the pressure rod 203 is mounted on the support seat 204. The rotation of the pressure rod 203 enables the first limiting shaft 20521 to slide within the first slide rail 20511, thereby achieving control over the up and down movement of the positioning shaft 2052. The support base 204 is fixed on the support frame 300 .

[0023] In some embodiments of the present invention, the number of the first limiting shafts 20521 is, for example, two. The two first limiting shafts 20521 are symmetrically arranged on the peripheral side wall of the positioning shaft 2052. Correspondingly, the control assembly is divided into two groups, that is, two groups of the pressure rods 203 and the support seats 204 are provided. The two sets of the pressure rods 203 and the support bases 204 are arranged on the same side of the support frame 300; The free ends of the two groups of pressure rods 203 are located on both sides of the positioning seat 2053 (that is, the two groups of floating plate positioning assemblies 205 are staggered on the same side of the support frame 300), which facilitates the rotation or positioning operations of the staff on both sides of the rotatable positioning device.

[0024] In some embodiments of the present invention, the compression rod 203 is rotatably connected to the support frame 300 via a connecting plate 207; A connecting seat 206 is fixedly provided on the connecting plate 207 , and the connecting seat 206 is rotatably connected to the pressing rod 203 .

[0025] In some embodiments of the present invention, the support base 204 is fixed to the support frame 300 via a connecting plate 207 .

[0026] In some embodiments of the present invention, the support base 204 includes a base 2041, a support sleeve 2042 integrally formed with the base 2041, and a support rod 2043, wherein the support rod 2043 is slidably embedded in the support sleeve 2042; A tray matching the pressure rod 203 is provided on the top of the support rod 2043, and the tray is provided for the support rod 2043 to support the pressure rod 203; like Figure 4 As shown, the pressing rod 203 is pressed downward, and the supporting rod 2043 slides in the supporting sleeve 2042 to achieve stable movement of the pressing rod 203; The pressure rod 203 is configured to control the opening of the float positioning assembly 205. The opening of the float positioning assembly 205 (the pressure rod 203 presses down the first limiting shaft 20521) causes the float positioning assembly 205 to be in an open state, that is, the positioning shaft 2052 and the rotation positioning hole 103 are in a disengaged state.

[0027] In certain embodiments of the present invention, the bottom of the positioning shaft 2052 is slidably connected to the positioning sleeve 2051 via a first spring. Specifically, one end of the first spring is fixed to the bottom of the positioning sleeve 2051, and the other end of the first spring is fixedly connected to the bottom of the positioning shaft 2052. The sliding connection between the positioning shaft 2052 and the positioning sleeve 2051 is achieved through the elasticity of the first spring. At the same time, after the pressure rod 203 is released, the positioning shaft 2052 can rebound to its original position. Specifically, The pressure rod 203 is released, and the pressure rod 203 returns to its original position under the support of the support rod 2043, so that the positioning shaft 2052 returns to its original position (the situation where the positioning shaft 2052 is aligned with the rotation positioning hole 103: the positioning shaft 2052 is inserted into the rotation positioning hole 103; the situation where the positioning shaft 2052 is not aligned with the rotation positioning hole 103: the positioning shaft 2052 is blocked by the floating plate 100 and cannot return to the inserted state).

[0028] In some embodiments of the present invention, the support sleeve 2042 is provided with a second slide rail 20421 , and the two side walls of the support rod 2043 are provided with a second limiting shaft 20431 , and the second limiting shaft 20431 is slidably provided on the second slide rail 20421 ; The sliding of the second limiting shaft 20431 in the second slide rail 20421 enables the sliding of the support rod 2043 in the support sleeve 2042 .

[0029] In certain embodiments of the present invention, the support rod 2043 is slidably embedded in the support sleeve 2042 through a second spring, one end of the second spring is fixed to the bottom of the support sleeve 2042, and the other end of the second spring is fixedly connected to the bottom of the support rod 2043. Through the elasticity of the second spring, the support rod 2043 is slidably embedded in the support sleeve 2042, and at the same time, the pressure rod 203 is able to rebound to its original position without the action of external force, thereby preventing the pressure rod 203 from still exerting pressure on the first limiting shaft 20521 when the pressure rod 203 is released, making the matching between the positioning shaft 2052 and the rotation positioning hole 103 unstable, thereby causing the occurrence of unstable positioning.

[0030] like Figure 2As shown, in some embodiments of the present invention, the rotation positioning assembly 200 further includes a plurality of supporting rollers 202, and the supporting rollers 202 are used to support the floating plate 100 to ensure the stability of the floating plate 100 during the rotation process; A plurality of support rollers 202 are arranged around the rotating disk 201 . For example, the number of the support rollers 202 is four.

[0031] In some embodiments of the present invention, the floating plate positioning assembly 205 further includes a positioning seat 2053 , and the positioning seat 2053 is fixed on the supporting frame 300 ; The positioning sleeve 2051 and the positioning seat 2053 are integrally formed.

[0032] In some embodiments of the present invention, the positioning seat 2053 is fixedly connected to the support frame 300 via the connecting plate 207 .

[0033] like Figure 5 As shown, the bottom of the support frame 300 is fixedly connected with a universal wheel 302. The setting of the universal wheel 302 facilitates the overall movement of the rotatable positioning device and facilitates the movement of the assembly to be assembled to the assembly position for assembly; The support frame 300 is provided with a traction mechanism 301, which includes a traction plate welded to the support frame 300 and traction holes provided on the traction plate. Reinforcement ribs are also welded between the traction plate and the support frame 300. The traction mechanism 301 is configured to be used by the AGV (drive device) to pull the rotary positioning device for transportation; A guide mechanism 303 is provided on both sides of the support frame 300. The guide mechanism 303 includes guide plates symmetrically welded on both sides of the support frame 300. The distance between the two guide plates matches the traction plate in the AGV, thereby realizing the guidance and conveying limitation of the AGV entering the rotation positioning device by the guide mechanism 303.

[0034] like Figure 2 As shown, in some embodiments of the present invention, the floating plate 100 is provided with a plurality of support blocks 101 and positioning pins 102; The positioning pins 102 are used to fix the floating plate 100 and the parts to be assembled, and the support blocks 101 are used to support the parts to be assembled. The support blocks 101 are also provided to adapt to parts to be assembled in different shapes, so that the floating plate 100 can support the parts to be assembled more stably.

[0035] In some embodiments of the present invention, the top of the free end of the pressing rod 203 is configured as a handle to facilitate operation by an operator.

[0036] In some embodiments of the present invention, the number of the rotation positioning holes 103 is, for example, four, which are the center points of the four sides of the floating plate 100 .

[0037] In certain embodiments of the present invention, the specific number of the rotation positioning holes 103 can be set according to the specific requirements when the floating plate 100 is actually rotated to receive assembly components, and the present invention does not limit this.

[0038] In certain embodiments of the present invention, the implementation process of the rotatable positioning device is as follows: Place the parts to be assembled on the floating plate 100 and fix them with the positioning pins 102; Press the pressing rod 203 to ensure that the rotation positioning hole 103 and the positioning shaft 2052 in the floating plate positioning assembly 205 are in a disengaged state, and (using external force) rotate the rotating plate 201 to drive the floating plate 100 to rotate; When the component to be assembled reaches the target position, the positioning shaft 2052 is inserted into the rotation positioning hole 103 to fix the floating plate 100, thereby positioning the component to be assembled.

[0039] A rotational positioning method for a rotatable positioning device according to some embodiments of the present invention includes: Rotation: By moving the positioning shaft 2052, the rotation positioning hole 103 and the positioning shaft 2052 are disengaged, and the rotation of the parts to be assembled on the floating plate 100 is completed by rotating the rotating plate 201; Positioning: The component to be assembled on the floating plate 100 is rotated to the target position, and the positioning shaft 2052 is moved to match the rotation positioning hole 103 and the positioning shaft 2052 to complete the positioning of the component to be assembled on the floating plate 100.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
