Description

Technical Field

[0001] This utility model relates to the technical field of track calibration, and in particular to a track pin hole coaxiality calibration tool. Background Technology

[0002] Tracks are important walking components of heavy construction machinery such as excavators and bulldozers. Tracks are composed of multiple track links connected by track pins and bushings.

[0003] Existing track pin hole coaxiality calibration tools, such as the coaxiality calibration device disclosed in utility model patent application number 202421653371.5, mainly include a worktable, with a fixed plate and a support plate fixedly installed on the top of the worktable, and a motor fixedly installed on the outer wall of the fixed plate. In use, the operator starts the electric telescopic rod according to the length of the workpiece, the L-shaped plate moves, so that the other end of the workpiece enters the triangular opening, and the third handle is rotated to fix the other end of the workpiece, thus completing the fixing.

[0004] However, most existing calibration tools are designed for calibrating the outer diameter of bearings and cannot be effectively applied to the inner diameter. Moreover, most existing calibration tools only measure the workpiece and cannot directly correct coaxiality deviations. Operators still need to make trial and error adjustments based on the measurement results, which is a very troublesome and inefficient process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a track pin hole coaxiality calibration tool that not only facilitates the detection of the coaxiality of the pin hole, but also allows for the correction of the pin hole after the detection is completed, eliminating the trouble of manual subsequent adjustment and improving work efficiency.

[0006] This utility model discloses a track pin hole coaxiality calibration tool, including a worktable; it also includes a rotating mechanism, two sets of fixing mechanisms, two sets of lifting mechanisms, a detection mechanism, and a calibration mechanism. The rotating mechanism is mounted on the worktable and drives the track to rotate. The two sets of fixing mechanisms are mounted on the rotating mechanism and fix the track. Both sets of lifting mechanisms are mounted on the worktable. The detection mechanism is mounted on the first set of lifting mechanisms and detects the coaxiality of the track pin holes. The calibration mechanism is mounted on the second set of lifting mechanisms and calibrates the track pin holes. The operator places the track on the rotating mechanism, and the two sets of fixing mechanisms fix the track. The rotating mechanism drives the track to rotate 90°. The first set of lifting mechanisms drives the detection mechanism to descend and detect the coaxiality of the first track pin hole. Then, the rotating mechanism drives the track to rotate 180° to facilitate the detection of the coaxiality of the second track pin hole. When the coaxiality of the pin hole is found to be unqualified, the rotating mechanism drives the track to rotate, moving the unqualified pin hole below the calibration mechanism. The second set of lifting mechanisms drives the calibration mechanism to descend and calibrate the track pin hole.

[0007] Preferably, the workbench includes a platform, two sets of side baffles, a controller, and a reinforcing bracket. The bottom of the platform is placed on the working surface, the bottom of the two sets of side baffles is connected to the top of the platform, the controller is installed on the side baffles, and the reinforcing bracket is installed between the two sets of side baffles. By setting two sets of side baffles for protection, accidental splashing during calibration is avoided to prevent injury to surrounding personnel. The reinforcing bracket improves the stability of the two sets of side baffles. The operator uses the controller to control the coaxiality calibration of the track pin holes.

[0008] Preferably, the rotating mechanism includes a first stepper motor, a reducer, a turntable, two sets of springs, and two sets of positioning blocks. The first stepper motor is mounted on the platform, and its power output end is connected to the power input end of the reducer. The power input end of the reducer is connected to the power input end of the turntable. The turntable has two sets of positioning holes, and the two sets of springs are respectively installed in the two sets of positioning holes. The bottom ends of the two sets of positioning blocks are respectively connected to the top ends of the two sets of springs. Two sets of side baffles are provided for protection to prevent accidental splashing during calibration and injury to surrounding personnel. The stability of the two sets of side baffles is improved by setting up reinforcing brackets. The operator uses a controller to control the coaxiality calibration of the track pin holes.

[0009] Preferably, the fixing mechanism includes a back plate, a hydraulic cylinder, and pads. The bottom end of the back plate is fixedly connected to the top end of the turntable. The hydraulic cylinder is mounted on the back plate, and the pads are mounted on the output end of the hydraulic cylinder. The two sets of fixing mechanisms are mounted opposite each other on the turntable. The two sets of hydraulic cylinders push the two sets of pads closer together, and the two sets of pads abut against both sides of the track to clamp and fix it.

[0010] Preferably, the lifting mechanism includes a geared motor, a reciprocating screw, a slider, and a guide rod. A groove is formed in the side baffle, and the geared motor is installed within this groove. The power output end of the geared motor is connected to the power input end of the reciprocating screw. The slider is slidably installed within the groove of the side baffle and connected to the reciprocating screw via a threaded transmission. The guide rod is installed on the platform, and the slider is slidably connected to the guide rod. Two sets of lifting mechanisms are respectively installed on two sets of side baffles. The controller starts the geared motor, which drives the reciprocating screw to rotate. The reciprocating screw drives the slider to reciprocate up and down. The guide rod, in conjunction with the slider, ensures the stability of the slider's lifting motion.

[0011] Preferably, the detection mechanism includes a second stepper motor, a drive shaft, and a scanning probe. The detection mechanism is mounted on a first set of sliders, and the second stepper motor is mounted on the sliders. The power output end of the second stepper motor is connected to the power input end of the drive shaft. The scanning probe is mounted on the drive shaft and is connected to the controller via an electrical signal. The sliders drive the detection mechanism to descend, causing the drive shaft to insert into the pin hole of the track. The second stepper motor drives the first stepper motor and the scanning probe to rotate. The scanning probe scans the inner wall of the track pin hole, and the coaxiality of the scanned pin hole is transmitted to the controller for judgment.

[0012] Preferably, the calibration mechanism includes a pull rod and a calibration head. The calibration mechanism is mounted on the second set of sliders. The top end of the pull rod is connected to the bottom end of the slider, and the top end of the calibration head is connected to the bottom end of the pull rod. The slider drives the pull rod and the calibration head to descend, and the calibration head is inserted into the pin hole to correct the deformed position in the pin hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator places the track on the rotating mechanism, two sets of fixing mechanisms fix the track, the rotating mechanism drives the track to rotate 90°, the first set of lifting mechanisms drives the detection mechanism to descend to detect the coaxiality of the first pin hole of the track, and then the rotating mechanism drives the track to rotate 180° to facilitate the detection of the coaxiality of the second pin hole of the track. When the coaxiality of the pin hole is found to be unqualified, the rotating mechanism drives the track to rotate so that the unqualified pin hole moves to the bottom of the calibration mechanism, and the second set of lifting mechanisms drives the calibration mechanism to descend to calibrate the track pin hole.
