Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0026] like Figure 1-3 As shown, a ring marking and positioning device includes a slide, a frame 1, a stop frame 2, and a bracket 11. The slide is placed on the ground through a base. The slide includes a plurality of drive rollers 5 distributed at intervals. The plurality of drive rollers 5 are located on the same horizontal plane. The drive rollers 5 are rotatably connected to the slide base and are synchronously driven through a sprocket. A marking station is provided on the slide, and a marking device is arranged at the marking station to perform workpiece marking operations.

[0027] The frame 1 is a door-type frame with two intervals on both sides of the slide. The frame 1 is straddled on the slide. Both sides above the frame 1 are respectively provided with slide rails extending in the driving direction of the slide. The slide rails can be dovetail-shaped troughs. Both ends of the stop frame 2 are slidably assembled on the slide rails through dovetail-shaped sliders matched with the slide rails. Studs threadedly connected to the sliders are provided inside the slide rails. One end of the stud is connected to a stepper motor, so as to realize the reciprocating drive of the stop frame 2 in the extension direction of the slide. The middle part of the stop frame 2 is correspondingly connected to a stop member 9 through a telescopic rod 4. The stop member 9 is strip-shaped, and its length is matched with the width of the slide. The stop member 9 is provided with a flat stop surface on the side corresponding to the workpiece. The position of the stop member 9 is adjusted by a stepper motor, and the stop member 9 is moved below to stop the workpiece through the stop surface, so as to accurately position it.

[0028] The bracket 11 is square and can be welded by square steel. The bracket 11 is located below the slide and opposite the marking station. A lifting member 8 is provided at the bottom of the bracket 11. The lifting member 8 can be 4 oil cylinders. Adjustment bolts are provided at the bottom of the oil cylinders, so that the bracket 11 can be kept horizontal through adjustment. A plurality of pallets 6 are fixed above the bracket 11. The plurality of pallets 6 are respectively connected to the gaps between adjacent driving rollers 5 corresponding to the marking stations. The length of the pallet 6 is adapted to the width of the slide, and the width is greater than the outer diameter of the driving roller 5. Therefore, under the drive of the lifting member 8, the plurality of pallets 6 pass through the gaps between the driving rollers 5 in the longitudinal direction to allow the workpiece to be upwardly separated from the driving roller 5.

[0029] The stopper 9 is driven longitudinally by the telescopic rod 4, and the telescopic joint can be an oil cylinder or a gas cylinder. After lifting the workpiece, the stopper 9 is lifted and moved above the workpiece, and the workpiece is fixed by longitudinal clamping, thereby ensuring stability during the marking process.

[0030] In an optional embodiment, the support plate 6 is fixed to the bracket 11 by bolts or welding, and both ends of the support plate 6 are bent upward to form a clamping groove. The overall width of the clamping groove is no greater than the gap between two adjacent driving rollers 5. A rubber plate is provided in the clamping groove, and the rubber plate extends upward from the upper surface of the support plate 6. The rubber plate reduces the hard contact with the workpiece to avoid damage to the surface quality of the workpiece.

[0031] In this embodiment, under normal circumstances, the workpiece after marking needs to be transferred to another workstation for storage or transportation. In order to facilitate the lifting of the workpiece, a notch is provided on the support plate 6 at the center line of the slideway to make way for the workpiece sling to pass through, or after the workpiece passes under the sling, the sling can be pulled out so that the workpiece can be quickly lifted and transferred.

[0032] In an optional embodiment, in order to adapt to different workpiece shapes, the rubber plate includes a plurality of rubber strips 7 spliced ​​to each other. For example, when targeting an annular workpiece, each independent rubber strip 7 can move independently, so that a portion of the rubber strip 7 can extend into the interior of the annular workpiece, thereby blocking the inner and outer walls of the annular workpiece, which can avoid radial displacement of the annular workpiece to a certain extent. A plurality of partitions 12 are provided inside the clamping groove to separate the plurality of rubber strips 7 to ensure the movement trajectory of each rubber strip 7.

[0033] In this embodiment, a reset spring 10 corresponding to the rubber strip 7 is provided at the bottom of the clamping groove, thereby ensuring that the rubber strip 7 can maintain a flat upper surface under normal conditions, and convex strips 13 corresponding to the two sides of the support plate 6 are provided on the upper edge of the rubber strip 7, which is stopped on the upper surface of the support plate 6 by the convex strips 13, thereby ensuring sufficient supporting capacity, and the length of the rubber strip 7 is adapted to the depth of the clamping groove. Specifically, after lifting the workpiece, the rubber strip 7 is pressed on the upper surface of the support plate 6 by the convex strips 13, and there is a certain space below to accommodate the reset spring 10. The specific length is selected according to the size of the spring, which will not be repeated here.

[0034] The partition plate 12 is fixed to the clamping groove by welding, so as to form a cavity independently corresponding to each rubber strip 7 , and the partition plate 12 is used to reinforce the support plate 6 to ensure the strength of the support plate 6 .

[0035] In an optional embodiment, the lower surface of the stopper 9 is provided with a flat bottom surface, through which the workpiece is stably clamped, and a rubber pad on one side of the bottom surface can be attached to avoid damage to the workpiece surface caused by squeezing with the workpiece.

[0036] In this embodiment, a driving member corresponding to the stop frame 2 is provided on the slide rail, and the driving member includes a stud and a stepper motor. A plurality of guide pillars 3 that are slid upward and assembled on the stop frame 2 are provided on the stop member 9, thereby ensuring the operating stability of the stop member 9.

[0037] There may be only one stepper motor, and the studs in the two slide rails are connected to the two ends of the transmission shaft through bevel gears respectively, and one of the studs or the transmission shaft is correspondingly connected to the stepper motor to realize synchronous driving on both sides.

[0038] For this application, marking can be performed by a semi-automatic marking machine, or fully automatic marking can be performed by a robotic arm driving the marking machine. When fully automatic marking is performed, a positioning rod that can be extended and retracted along the width direction is provided on the side of the slide. The positioning rod can be driven by an electromagnetic push rod, and a touch switch pointing to the workpiece is provided at its end. The positioning rod is driven by an electromagnetic push rod or a screw driven by a stepper motor. The specific coordinates of the workpiece are determined by the relative extension and retraction of the touch switch and the electromagnetic push rod after touching the workpiece, or the number of rotations of the stepper motor, thereby ensuring the accuracy of the marking.

[0039] Alternatively, a distance meter is provided above and on the side of the slideway corresponding to the marking station, and the distance meter, marking machine and robotic arm are connected to the controller accordingly, so that the specific position of the workpiece can be fed back by the distance meter for accurate marking.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
