[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] A fast and accurate positioning and punching device for a cross-axis universal joint comprises a base 1, a punching device 4 is arranged on the top of the base 1, a rotating mechanism 3 is arranged on the top of the base 1, and a positioning mechanism 2 is arranged on the top of the base 1 for fast and accurate positioning and punching of the cross-axis universal joint, wherein the positioning mechanism 2 comprises:

[0027] The lifting assembly 21 is arranged on the top of the base 1, and includes a lifting box 211 fixedly installed on the top of the base 1. A lifting push rod 212 is fixedly installed inside the lifting box 211. The model of the lifting push rod 212 is SLEL205, which is electrically connected to an external power supply and can be opened and closed by a person operating a control panel. A mounting plate 213 is fixedly installed on the top of the lifting push rod 212.

[0028] The centering component 22 is arranged on the top of the mounting plate 213, and includes a mounting frame 221 fixedly mounted on the top of the mounting plate 213. A right clamping rod 222 is movably mounted on the right side of the inner cavity of the mounting frame 221 through a connecting block, and a right roller 223 is movably mounted on the rear end of the right clamping rod 222, and a right clamping arc block 224 is movably mounted on the front end of the right clamping rod 222, and two right limit columns 229 are fixedly mounted on the top of the right clamping arc block 224, and a left clamping rod 225 is movably mounted on the left side of the inner cavity of the mounting frame 221 through a connecting block, and the rear end of the left clamping rod 225 is movably mounted. A left roller 226 is installed, and a left clamping arc block 227 is movably installed at the front end of the left clamping rod 225, and two left limit columns 2210 are fixedly installed on the top of the left clamping arc block 227. The electric push rod 234 operates to push the triangular block 236 to move. The movement of the triangular block 236 causes the right clamping rod 222 to rotate clockwise through the right roller 223 and the left roller 226, and the left clamping rod 225 to rotate counterclockwise, so that the right clamping arc block 224 and the left clamping arc block 227 move synchronously towards each other to center and clamp the end of the cross-axis universal joint, thereby realizing fast and accurate positioning and punching;

[0029] The kinetic energy component 23 is disposed on the top of the mounting plate 213 and is used to provide motion kinetic energy to the kinetic energy component 23 .

[0030] In this embodiment, the kinetic energy component 23 includes a track plate 231 fixedly mounted on the top of the mounting plate 213, a trapezoidal groove 232 is opened inside the track plate 231, a guide block 233 is fixedly mounted on the top of the track plate 231, an electric push rod 234 is movably mounted inside the guide block 233, the model of the electric push rod 234 is SLEL205, it is electrically connected to an external power supply and the opening and closing operations are realized by a person operating the control panel, one end of the electric push rod 234 is connected to a triangular block 236 through a connecting block, and a trapezoidal slider 235 is fixedly mounted on the bottom of the triangular block 236, the electric push rod 234 runs to push the triangular block 236 to move, and the movement of the triangular block 236 causes the right clamping rod 222 to rotate clockwise and the left clamping rod 225 to rotate counterclockwise through the right roller 223 and the left roller 226, thereby realizing the operation of the centering component 22.

[0031] In this embodiment, the rotating mechanism 3 includes a motor box 31 fixedly installed on the front side of the lifting box 211, and a driving motor 32 is fixedly installed inside the motor box 31. The driving motor 32 is a three-phase asynchronous motor, which is electrically connected to an external power supply and is opened and closed by a person operating the control panel. The motor shaft of the driving motor 32 passes through a turntable 33 fixedly installed in front of the motor box 31, and a clamping block 34 is fixedly installed on the front of the turntable 33. The cross-axis universal joint is clamped into the two clamping blocks 34. At the same time, the rotating rod 36 is rotated to align the positioning stud 37 with the center part of the cross-axis universal joint, and the positioning stud 37 is rotated. The column 37 is used to fix the cross-axis universal joint. A fixing rod 35 is fixedly installed on the front side of the turntable 33, and a rotating rod 36 is rotatably installed on the front end of the fixing rod 35, and a positioning stud 37 is installed on one end of the rotating rod 36 through which a thread is rotatably installed. The movement of the lifting push rod 212 drives the mounting plate 213 to move up and down. The movement of the mounting plate 213 up and down drives the centering component 22 and the kinetic energy component 23 to move up and down at the same time, so that the left clamping arc block 227 and the right limit column 229 do not hinder the rotating mechanism 3 from driving the cross-axis universal joint to rotate and continuously punch holes, thereby achieving unrestricted continuity while achieving precise positioning.

[0032] In this embodiment, the rear end of the right clamping rod 222 and the rear end of the left clamping rod 225 are connected by a left tension spring 228 installed on the top fixed column at the rear ends of the right clamping rod 222 and the left clamping rod 225. The clamping block 34 operates to pull the triangular block 236. At this time, the left tension spring 228 drives the left clamping rod 225 and the right clamping rod 222 to move in opposite directions through its own elasticity, thereby realizing the cancellation of the centering clamping of the cross-axis universal joint.

[0033] In this embodiment, the left roller 226 and the right roller 223 are in contact with the left and right sides of the triangular block 236. The movement of the triangular block 236 can drive the right roller 223 and the triangular block 236 to move left and right, thereby realizing the clockwise rotation of the right clamping rod 222 and the counterclockwise rotation of the left clamping rod 225.

[0034] In this embodiment, the trapezoidal slider 235 is adapted to slide inside the trapezoidal groove 232 , thereby limiting the movement of the triangular block 236 .

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] When working, the user first connects the device to an external power source, then inserts the cross-axis universal joint into the two clamping blocks 34, and at the same time rotates the rotating rod 36 to align the positioning stud 37 with the center part of the cross-axis universal joint, and rotates the positioning stud 37 to fix the position of the cross-axis universal joint. Then, the electric push rod 234 operates to push the triangular block 236 to move. The triangular block 236 moves through the right roller 223 and the left roller 226 to make the right clamping rod 222 rotate clockwise, and the left clamping rod 225 rotates counterclockwise, so that the right clamping arc block 224 and the left clamping arc block 227 move synchronously towards each other to center the end of the cross-axis universal joint, and then the hydraulic rod of the punching device 4 operates to drive the punching rotary head to descend. The cross-axis universal joint is punched, and then the electric push rod 234 runs to pull the triangular block 236. At this time, the left tension spring 228 drives the left clamping rod 225 and the right clamping rod 222 to move in the opposite direction through its own elasticity, canceling the centering clamping of the cross-axis universal joint. Then the lifting push rod 212 moves to drive the mounting plate 213 to move up and down. The mounting plate 213 moves up and down and drives the centering component 22 and the kinetic energy component 23 to move up and down at the same time, moving the right clamping arc block 224 and the left clamping arc block 227 out of the end of the cross-axis universal joint. Then the driving motor 32 runs to drive the turntable 33 to rotate, thereby driving the cross-axis universal joint to rotate. The above steps are repeated to continuously and accurately position and punch holes for the cross-axis universal joint.
