DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1-Figure 5 As shown, a rotary body axle assembly equipment for remote control vehicle assembly includes a frame 1, and the body axle assembly equipment also includes a turntable 21 rotatably mounted on the frame 1, and a plurality of conveyor lines 22 are fixed on the frame 1 along the circumference of the axis of the turntable 21, and mechanical grippers 23 are installed on the conveyor lines 22 corresponding to the stations on the turntable 21 for controlling the loading and unloading of the body, and shaft clamps 24 are installed on the conveyor lines 22 corresponding to the stations on the turntable 21 for installing the axles, and a motor 25 is installed on the frame 1, and the output shaft of the motor 25 is connected to the center line of the turntable 21 for transmission; the turntable 21 is provided with an assembly component 3 for accurately positioning the installation position of the body and the axle.

[0027] Four assembly components 3 are arranged on the turntable 21, and the number of assembly components 3 can be increased according to the change of the assembly structure. The four assembly components 3 are used for loading the car body, installing the axle at one end of the car body, installing the axle at the other end of the car body, and unloading the assembled car body and axle in sequence. During the processing, the running motor 25 controls the rotation of the turntable 21. The rotation of the turntable 21 drives the assembly components 3 to perform circular motion, and the rotation position of the assembly components 3 corresponds to the position of the conveyor line 22. The car body and axle on the conveyor line 22 are grasped by mechanical claws 23 and shaft clamps 24, and the grasped car body and axle are moved and conveyed to the assembly components 3 to complete the assembly operation of the car body and the axle. The assembly components 3 can autonomously adjust the state of the limited car body according to the change of the work station after the circular rotation, so as to control the loading and unloading of the car body and increase the degree of automation of the assembly equipment.

[0028] See also Figure 1-Figure 6 As shown, the assembly component 3 includes a plurality of assembly tables 31 fixed on the surface of the turntable 21 along the circumference of the axis thereof, the turntable 21 is provided with slide grooves 32 along the four sides of the assembly tables 31, the slide grooves 32 are slidably connected with a sliding frame 33, and a clamping block 34 is fixedly installed on the sliding frame 33; a floating limit mechanism 35 for floatingly limiting the assembly position of the vehicle body is provided in the assembly table 31.

[0029] When the sliding frame 33 moves along the slide groove 32, the sliding frame 33 drives the clamping block 34 to move synchronously, so that the clamping block 34 moves closer to or away from the vehicle body in the assembly table 31. When the vehicle body assembly position needs to be limited, the four groups of clamping blocks 34 move synchronously close to the vehicle body, and the front and rear groups of clamping blocks 34 clamp and limit the front and rear sides of the vehicle body. At the same time, the left and right groups of clamping blocks 34 will move and push the floating limiting mechanism 35 to clamp and fix it from the left and right sides of the vehicle body. The clamping blocks 34 and the floating limiting mechanism 35 are used to limit multiple directions of the vehicle body to maintain the stability of the vehicle body assembly position.

[0030] See also Figure 3-Figure 6 As shown, a fixed cover 41 is fixedly installed on the assembly table 31, a movable cover 42 is slidably sleeved on the fixed cover 41, and a return spring 43 is connected between the movable cover 42 and the fixed cover 41; a driving rod 44 is rotatably connected to the movable cover 42, and the driving rod 44 is rotatably connected to the sliding frame 33.

[0031] When the movable cover 42 is sleeved on the outside of the fixed cover 41 and moves up and down, the driving rod 44 connected between the movable cover 42 and the sliding frame 33 rotates accordingly. The rotating driving rod 44 pushes the sliding frame 33 to slide along the direction of the slide groove 32, thereby achieving the purpose of synchronously adjusting the movement of the clamping blocks 34 on the four sides of the assembly table 31, thereby quickly controlling the assembly limit of the vehicle body in the assembly table 31.

[0032] See also Figure 2 and Figure 3 As shown, a beveled ring 45 is fixedly mounted on the frame 1, and the beveled area of ​​the beveled ring 45 corresponds to the distribution position of the conveyor line 22 for controlling the loading and unloading of the vehicle body; the outer corner of the bottom of the movable cover 42 is an arc-shaped structure, and the movable cover 42 and the surface of the beveled ring 45 fit each other.

[0033] When the turntable 21 rotates, the movable cover 42 at the bottom of the turntable 21 rotates along with it, and the bottom of the movable cover 42 fits against the surface of the inclined circular ring 45. Due to the change in the inclination of the surface of the inclined circular ring 45, the movable cover 42 undergoes longitudinal displacement during the circular rotation, thereby controlling the movable cover 42 to be sleeved on the outside of the fixed cover 41 and move longitudinally. The movable cover 42 moves up and down during the circular rotation to adjust the movement state of the clamp 34 on the four sides of the assembly table 31, thereby realizing the function of automatically adjusting the vehicle body position limit state according to the change of the assembly table 31 workstation.

[0034] See also Figure 4-Figure 8 As shown, the floating limiting mechanism 35 includes a guide rod 351 fixed to the inner wall of the assembly platform 31 , a floating frame 352 is slidably connected to the guide rod 351 , and a limiting spring 353 is connected between the floating frame 352 and the guide rod 351 .

[0035] When the clamping blocks 34 on the left and right sides of the assembly table 31 move close to the direction of the vehicle body, the clamping blocks 34 first contact the floating frames 352, and the clamping blocks 34 move to push the floating frames 352 to move along the direction of the guide rod 351. The floating frames 352 stretch the limit springs 353, and the floating frames 352 on both sides will move and clamp and fix on the left and right sides of the vehicle body. The floating frames 352 have a wide clamping range and can relatively stably confine the vehicle body in the assembly table 31. At the same time, the limit springs 353 are connected between the floating frames 352 and the guide rods 351. Under the action of the elastic structure, the local impact force during the assembly of the vehicle body and the axle can be buffered to keep the assembly of the vehicle body and the axle stable.

[0036] See also Figure 4 and Figure 5 As shown, the assembly table 31 is provided with an ejection assembly 5 for controlling the autonomous discharge of the vehicle body axle after assembly.

[0037] When the turntable 21 controls the assembly table 31 to rotate to the last unloading station, the clamping block 34 in the assembly table 31 moves away from the vehicle body, and the vehicle body is in a loose state. The ejection assembly 5 can push the vehicle body upward so that the mechanical clamp 23 grabs the vehicle body and moves it to the conveyor line 22.

[0038] See also Figure 4 and Figure 5 As shown, the ejection assembly 5 includes a cylinder 51 fixed on the assembly platform 31 , and an output end of the cylinder 51 is fixedly connected to a bottom plate 52 , and the bottom plate 52 is arranged between two groups of floating limit mechanisms 35 .

[0039] The cylinder 51 drives the bottom plate 52 to move upward, and the bottom plate 52 drives the vehicle body placed on the surface to move upward synchronously, so that the vehicle body is away from the clamping block 34 and the floating limit mechanism 35, and there is no obstruction around the vehicle body, so that the mechanical gripper 23 moves to grab the vehicle body.

[0040] Working principle: There are four workstations on the turntable 21, the first workstation is used for loading the car body, the second workstation is used for loading the axle and assembling the axle with one side of the car body, the third workstation is used for loading the axle and assembling the axle with the other side of the car body, and the fourth workstation is used for unloading the assembled car body and axle; when assembling the car body and the axle, the car body and the axle are respectively conveyed to the turntable 21 on different conveyor lines 22, and the car body is first grasped by the mechanical gripper 23 and placed on the assembly table 31 of the first workstation on the turntable 21, and the operating motor 25 controls the turntable 21 to rotate, and the turntable 21 drives the assembly table 31 on the surface to rotate in a circle, and the corresponding processing station of the assembly table 31 is switched, When the assembly table 31 rotates to the second station, the axle transported on the conveyor line 22 is clamped by the shaft clamp 24, and the axle is moved to the top of the assembly table 31, and the axle and one end of the vehicle body are controlled to be assembled with each other. After assembly, the turntable 21 is rotated to make the assembly table 31 rotate to the third station, and the axle transported on the conveyor line 22 is clamped by the shaft clamp 24 again, and the axle is moved to the top of the assembly table 31, and the axle and the other end of the vehicle body are controlled to be assembled with each other. Finally, the turntable 21 is rotated to control the assembly table 31 to rotate to the fourth station, the vehicle body is grasped by the mechanical clamp 23, and the assembled vehicle body and axle are moved to the conveyor line 22 for outward output, thereby realizing the assembly of the vehicle body and the axle.

[0041] When the turntable 21 is rotated to switch the processing station of the assembly table 31, the position of the clamping block 34 corresponding to the outside of the assembly table 31 changes according to the change of the station, thereby realizing the autonomous limit of the vehicle body. The assembly table 31 controls the movable cover 42 to fit the surface of the inclined ring 45 and rotate in a circle during the circular rotation. According to the change of the inclination of the surface of the inclined ring 45, the movable cover 42 is longitudinally displaced during the circular rotation, thereby realizing the longitudinal movement of the movable cover 42. The two ends of the driving rod 44 connected between the movable cover 42 and the sliding frame 33 rotate to push the sliding frame 33 and the clamping block 34 to move, thereby controlling the clamping block 34 to move close to the surface of the inclined ring 45. When the assembly table 31 is in the loading and unloading position of the vehicle body, the movable cover 42 moves downward under the elastic thrust of the return spring 43, and the clamping block 34 is controlled to move away from the vehicle body under the transmission action of the driving rod 44 and the sliding frame 33, so as to control the loading and unloading of the vehicle body on the assembly table 31; when the assembly table 31 rotates to correspond to the axle assembly station, the movable cover 42 moves to the high position of the inclined ring 45, and the movable cover 42 moves upward, and the clamping block 34 is controlled to move close to the vehicle body under the transmission action of the driving rod 44 and the sliding frame 33, so as to limit the assembly position of the vehicle body and keep the vehicle body assembly in a stable state.

[0042] When the clamping blocks 34 on the left and right sides of the assembly table 31 move, they first contact the floating frame 352, pushing the floating frame 352 to move to the left and right sides of the vehicle body. The floating frame 352 has a wide clamping range, keeping the vehicle body stably set in the assembly table 31, and when assembling the vehicle body and the axle, the floating frame 352 can buffer the local assembly punching force through the limit spring 353 connected to the side, thereby further maintaining the stability of the vehicle body assembly.

[0043] When the assembly table 31 rotates to the unloading station, the operating cylinder 51 pushes the bottom plate 52 upward, and the bottom plate 52 drives the surface-assembled car body and axle to move upward. At this time, there is no obstruction around the car body, which facilitates the control of the mechanical gripper 23 to grab the car body and realize mechanical unloading.

[0044] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
