And through the cooperative matching of laser ranging sensor, electric push rod and other components in left positioning mechanism and right positioning mechanism, the positioning effect of machining is improved.

[0005] To solve the above problems, the technical scheme provided by the utility model is as follows:

[0006] A novel workpiece trimming machine with a positioning structure includes a base, a cutting blade, a trimming table at the processing station, and a stabilizing rolling mechanism. A fixed column is fixedly installed on the upper left end of the base, and a hydraulic cylinder is fixedly installed on the upper end of the fixed column. The output end of the hydraulic cylinder is fixedly connected to a lifting plate. A slot is opened on the adjusting seat, and a lead screw is installed in the slot. One end of the lead screw is fixedly connected to the output end of a servo motor, and the other end of the lead screw is rotatably connected to the inner wall of the slot. An adjusting seat is threaded onto the outer side of the lead screw. A connecting plate is installed below the adjusting seat, and the cutting blade is fixedly installed below the connecting plate. The stabilizing rolling mechanism is provided on both the left and right sides of the cutting blade. A turntable is provided above the base, and the trimming table at the processing station is installed on the upper end of the turntable. A left positioning mechanism is provided on the upper left end of the trimming table at the processing station, and a right positioning mechanism is provided on the upper right end of the trimming table at the processing station.

[0007] Furthermore, the left positioning mechanism includes a push plate, an electric push rod, a laser rangefinder sensor, a guide rod, and a vertical plate. The electric push rod is fixedly installed on the right side of the vertical plate, and its output end is fixedly connected to the push plate. Two guide rods are symmetrically arranged on the front and rear sides of the electric push rod, and the guide rods movably pass through the vertical plate and are fixedly connected to the push plate. The right positioning mechanism includes a push plate, an electric push rod, a laser rangefinder sensor, a guide rod, and a vertical plate. The electric push rod is fixedly installed on the left side of the vertical plate, and its output end is fixedly connected to the push plate. Two guide rods are symmetrically arranged on the front and rear sides of the electric push rod, and the guide rods movably pass through the vertical plate and are fixedly connected to the push plate.

[0008] Furthermore, the first laser rangefinder sensor is fixedly installed on the first vertical plate, and the first laser rangefinder sensor is disposed between the first electric push rod and the first guide rod; the second laser rangefinder sensor is fixedly installed on the second vertical plate, and the second laser rangefinder sensor is disposed between the second electric push rod and the second guide rod.

[0009] Furthermore, a rotating motor is fixedly installed at the upper right end of the crossbeam, the output end of the rotating motor is fixedly connected to the rotating rod, the lower end of the rotating rod is fixedly connected to the center of the turntable, a sliding column is fixedly installed at the lower end of the turntable, and a sliding groove is opened on the upper surface of the base, with the sliding column slidably connected to the sliding groove.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The system features four trimming stations evenly distributed in a ring on the turntable. During actual machining, while a workpiece is being trimmed on one station, the operator can simultaneously perform preparatory work such as loading and unloading workpieces on other idle stations. For example, in machining a batch of metal parts, these four stations allow for continuous, cyclical operation, significantly reducing waiting time and improving overall processing efficiency. Compared to existing technologies with only one trimming station, this system can complete trimming tasks on more workpieces per unit time.

[0014] 2. This is achieved through the coordinated operation of components in the left and right positioning mechanisms. The left positioning mechanism consists of push plate one, electric push rod one, laser rangefinder one, guide rod one, and vertical plate one. The right positioning mechanism consists of push plate two, electric push rod two, laser rangefinder two, guide rod two, and vertical plate two. Laser rangefinder one is fixedly mounted on vertical plate one (between electric push rod one and guide rod one), and laser rangefinder two is fixedly mounted on vertical plate two (between electric push rod two and guide rod two). They can accurately measure the distance information from the workpiece to the corresponding positioning mechanism. For example, when processing electronic components, their dimensions are often small and require high precision. After the laser rangefinder accurately obtains the distance data, electric push rod one and electric push rod two will push push plate one and push plate two accordingly based on the measurement results, thereby accurately positioning the workpiece and ensuring the accurate position of the workpiece during the edge cutting process.

[0015] In summary, this novel workpiece trimming machine with a positioning structure has wide applicability, solving the problems mentioned in the background art, such as low processing efficiency, a single workpiece trimming station, poor adaptability to different workpiece specifications, and relatively fixed equipment structure.

[0035] The laser ranging sensor one 703 and the laser ranging sensor two 803 are conventional devices in the field, and the electrical elements are connected through an industrial Ethernet or a wireless communication module. The laser time-of-flight principle is that the sensor emits a laser pulse, which is reflected back after being shot at the target object. The sensor measures the time interval experienced from emission to reception of the laser pulse, and combines the speed of light (which is approximately constant in air) to calculate the distance from the target object using the formula "distance = speed of light x time interval ÷ 2" (divided by 2 because the laser travels back and forth).

[0036] The phase difference principle is that the sensor emits a modulated continuous laser beam. After the laser is reflected back by the target object, the phase difference between the emitted laser and the reflected laser is detected, and parameters such as modulation frequency are combined to calculate the distance. This method is commonly used in scenarios of close-range high-precision measurement.

[0037] In the edge trimmer for workpiece processing, when the equipment is started and the workpiece is positioned, two sensors respectively emit laser beams towards the corresponding workpiece, then receive the laser signals reflected from the surface of the workpiece, and then calculate the distance between each sensor and the workpiece in real time, and continuously transmit the distance data to the control system.

[0038] And the electrical components appearing in the text are all electrically connected with the main controller and power supply, and the main controller can be a computer and other conventional known devices for control.
