[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In one embodiment, Figure 1-Figure 5As shown, a pull rod assembly assembly device includes a base 11, a bottom plate 12 is fixed to the middle of the upper end of the base 11, a fixing plate 13 is fixed to the rear side of the upper end of the bottom plate 12, one end of the fixing plate 13 is symmetrically provided with two round holes 17, a display piece 18 is fixed to the middle of the upper end of the bottom plate 12, the display piece 18 includes a fixing column 181, the fixing column 181 is fixedly installed in the middle of the upper end of the bottom plate 12, a first return spring 182 is installed inside the fixing column 181, the upper end of the first return spring 182 is fixedly connected to the return plate 183, the return plate 183 is slidably installed inside the fixing column 181, and the return plate 182 is fixedly installed inside the fixing column 181. A movable column 184 is fixed at the upper end, and a positioning pin 185 is fixed at the middle of the upper end of the movable column 184. Two limit members 22 are fixed to the left and right sides of the upper end of the bottom plate 12, and the two limit members 22 are located in front of the display member 18. A first support member 19 and a second support member 20 are fixed to the left and right sides of the upper end of the bottom plate 12, and the first support member 19 and the second support member 20 are located in front of the two limit members 22. The upper end of the bottom plate 12 is fixedly connected to the top plate 15 through a connecting rod 14. A pressing member 23 is arranged between the bottom plate 12 and the top plate 15, and a driving block 24 for driving the adjusting member 25 is fixed to the rear end of the pressing member 23.

[0027] In this embodiment, the rod portion of the rod assembly is first placed on the left limit piece 22, and the round heads at both ends of the rod assembly are placed on the display piece 18 and the first support piece 19 respectively. Then, the bushing is placed on the round head located on the display piece 18, and the center hole of the bushing passes through the positioning pin 185. When it is necessary to press-fit the components of the rod assembly, the press-fitting piece 23 moves downward to apply pressure to the bushing to ensure that the bushing can be assembled into the bushing hole of the round head. During the press-fitting process, the first return spring 182 is compressed and contracted, and when the press-fitting is completed, the first return spring 182 rebounds; then the staff places the rod portion of the rod assembly on the right limit piece 22, and the round head of the rod assembly with the bushing assembled is placed on the second support piece 20, and the unassembled round head is placed on the display piece 18. The above operation is repeated until the rod assembly is assembled.

[0028] In one embodiment, Figure 3 As shown, the limiting member 22 includes a limiting column 221 , and the limiting column 221 is fixedly mounted on the upper end of the bottom plate 12 . Two limiting blocks 222 are symmetrically fixed on the upper end of the limiting member 22 .

[0029] The limit block 222 is symmetrically fixed on the upper end of the limit column 221 to form a lateral limit on the tie rod assembly. This prevents the tie rod assembly from sliding out of the limit piece 22 due to uneven force or improper operation during assembly, ensuring the stability and safety of the assembly process. The shape and position design of the limit block 222 can guide the tie rod assembly to be placed in a predetermined direction, which helps the staff to quickly and accurately adjust the position of the tie rod assembly during assembly, ensuring the accuracy and consistency of assembly.

[0030] In one embodiment, Figure 3 and Figure 4 As shown, the first support member 19 includes a first support column 191 fixed to the upper end of the base plate 12, and a first positioning column 192 is fixed to the upper end of the first support column 191. The second support member 20 includes a second support column 201 fixed to the upper end of the base plate 12, and a second positioning column 202 is fixed to the upper end of the second support column 201.

[0031] The first support member 19 and the second support member 20 work together to provide stable support and accurate positioning for the tie rod assembly, which helps to ensure that the round heads at both ends of the tie rod assembly can maintain the correct position and angle during the press-fitting process, thereby ensuring that the bushing can be accurately assembled into the bushing hole.

[0032] In one embodiment, Figure 3 As shown, the display member 18 is symmetrically provided with a pressing member 21 at the left and right ends, and the pressing member 21 includes a rotating motor 211 installed at the upper end of the base plate 12, the output end of the rotating motor 211 is fixedly connected to an electric push rod 212, the telescopic end of the electric push rod 212 is fixedly connected to a connecting plate 213, and a pressing block 214 is fixed to the bottom of the other end of the connecting plate 213.

[0033] The rotating motor 211 is used to adjust the initial position or angle of the electric push rod 212 to ensure that the pressing block 214 can be accurately aligned and pressed down on the target object. The electric push rod 212 drives the pressing block 214 to perform the pressing operation through the telescopic movement. The connecting plate 213 serves as a connecting bridge between the electric push rod 212 and the pressing block 214, transmitting the telescopic movement of the electric push rod to the pressing block 214. The pressing block 214 directly contacts the pressed object to realize the pressing function.

[0034] In one embodiment, Figure 2 As shown, the pressing part 23 includes a cylinder 231 installed on the upper end of the top plate 15, a piston rod 233 is fixed to the output end of the cylinder 231, a pressing plate 234 is fixed to the bottom end of the piston rod 233, two guide rods 232 are fixed to the upper end of the pressing plate 234, the two guide rods 232 slide and extend to the upper end of the top plate 15, and a pressing block 235 is fixed to the middle of the lower end of the pressing plate 234.

[0035] The press-fitting part 23 drives the press-fitting plate 234 to move up and down through the cylinder 231, and uses the press-fitting block 235 to press the pressed object. This design allows the press-fitting process to be carried out smoothly and accurately, improving the press-fitting efficiency and accuracy. The guide rod 232 guides the press-fitting plate 234 to move up and down in the vertical direction.

[0036] In one embodiment, Figure 3 and Figure 5 As shown, a sliding opening 16 matching the driving block 24 is formed through the upper end of the bottom plate 12 , and an adjustment surface 241 , a buffer surface 242 , a driving surface 243 and a reset surface 244 are sequentially provided at the front end of the driving block 24 from top to bottom.

[0037] The different surface designs at the front end of the driving block 24 enable it to play different roles in different working stages. For example, in the adjustment stage, the adjustment surface 241 contacts the pressed object to ensure that the pressed object does not move; in the driving stage, the driving surface 243 contacts the pressed object to transmit the driving force to adjust the position of the pull rod assembly to be assembled to ensure that the bushing can be assembled into the bushing hole of the round head; in the reset stage, the reset surface 244 guides the pressed object to return to the initial position.

[0038] In one embodiment, Figure 5 As shown, the adjusting member 25 includes an adjusting block 251 , the front end of which is provided with an arc surface 252 , the rear end of which is fixed with a moving block 254 , the upper end of which is provided with a movable opening 255 , and the inside of which is provided with an abutting surface 253 matching the driving surface 243 .

[0039] The movement trajectory of the driving block 24 is adjusted and controlled by the cooperation between the moving block 254 and the movable opening 255, and the contact and cooperation between the abutting surface 253 and the driving surface 243. The arc surface 252 contacts the round head of the pull rod assembly, thereby adjusting its position to ensure that the bushing can be assembled into the bushing hole of the round head.

[0040] In one embodiment, Figure 5 As shown, a reset member 26 is fixed to the rear end of the adjusting member 25, and the reset member 26 includes a reset rod 261 matching the circular hole 17, and a second reset spring 262 is arranged outside the reset rod 261, and the front end of the second reset spring 262 is fixedly connected to the fixing plate 13, and the rear end of the second reset spring 262 is fixedly connected to the limiting plate 263, and the limiting plate 263 is fixedly connected to the reset rod 261.

[0041] The reset member 26 realizes the reset function of the adjustment member 25 through the cooperation of the reset rod 261, the second reset spring 262, the fixing plate 13 and the limit plate 263. When the pull rod assembly is assembled, the press-fitting member 23 moves upward, thereby driving the driving block 24 to move upward, and the second reset spring 262 releases the stored energy to push the adjustment member 25 to move along the direction of the reset rod 261 until it returns to the initial position.

[0042] The above embodiment discloses a tie rod assembly assembly device, wherein the staff first places the tie rod part of the tie rod assembly on the limit piece 22 on the left, and the round heads at both ends of the tie rod assembly are placed on the display piece 18 and the first support piece 19 respectively. Next, the bushing is placed on the round head located on the display piece 18, and the center hole of the bushing passes through the positioning pin 185, ready for press-fitting. Subsequently, the rotating motor 211 of the left side pressing piece 21 adjusts the position of the pressing block 214, and the electric push rod 212 causes the pressing block 214 to press the tie rod part to prevent the tie rod assembly from moving up and down, and the cylinder 231 drives the press-fit piece 23 to move downward. The press-fit plate 234 and the press-fit block 235 apply pressure to the bushing to ensure that the bushing can be assembled into the bushing hole of the round head. At the same time, during the press-fitting process, the driving block 24 moves downward with the press-fitting part 23, so that the driving surface 243 of the driving block 24 abuts against the abutting surface 253 of the adjusting part 25, thereby causing the adjusting part 25 to move forward, and the arc surface 252 at the front end of the adjusting block 251 contacts the round head part of the pull rod assembly, thereby adjusting the position of the round head part to ensure that the bushing can be assembled into the bushing hole of the round head. During the press-fitting process, the first return spring 182 in the display part 18 is compressed and contracted. When the press-fitting is completed, the press-fitting part 23 moves upward. Under the rebound action of the second return spring 262 of the return part 26, the adjusting part 25 is reset, and the first return spring 182 rebounds, so that the movable column 184 and the positioning pin 185 return to their initial positions. The left lower pressing part 21 is reset. After completing a press-fitting, the staff places the pull rod part of the pull rod assembly on the right limiter 22, the round head with the bushing installed is placed on the second support member 20, and the unassembled round head is placed on the display part 18. Repeat the above press-fitting operation until the tie rod assembly is completely assembled.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
