Description

Technical Field

[0001] The utility model belongs to the technical field of engraving detection, and particularly relates to a rotor engraving detection device. Background Technique

[0002] During the production of motor rotors, a grooving machine is required to engrave grooves on the surface of the rotors. To improve the quality of rotor die casting and better manage different types of products, serial numbers need to be marked on the die-cast rotors. By making marks on the die-casting molds, the produced die-cast rotors can be identified, but the marks on the molds are not easy to change, and the fixed marks have limitations; while using a laser marking machine for marking, the marking method is flexible and convenient.

[0003] The patent with the application number 201820154801.7 discloses a rotor engraving machine, belonging to the technical field of motors. It includes a feeding part, an engraving main machine, and a discharging part. The engraving main machine includes a hydraulic press, a workbench, an engraving mechanism, and a rotating table. The rotating table is arranged in the middle of the workbench, guiding columns are arranged on the workbench, the hydraulic press is arranged at the top of the guiding columns, a hydraulic cylinder is arranged in the middle of the hydraulic press, the bottom end of the piston rod of the hydraulic cylinder is connected with a mounting plate, and the engraving mechanism is arranged in the middle of the mounting plate. The engraving mechanism consists of a counter and an engraving head. A side plate is arranged on one side of the guiding column, and an upper limit inductor, a lower limit inductor, and a pressure inductor are arranged on the side plate from top to bottom in sequence. Six engraving jigs are evenly arranged on the rotating table.

[0004] The above technical solution lacks the detection of the rotor after engraving. After engraving, the rotor needs to be conveyed by a conveyor belt. The traditional detection method uses a camera fixed on the conveyor belt to take pictures, and the detection is carried out by observing the engraved grooves of the rotor on the pictures. However, since the rotor is always in a moving state, the camera is prone to ghosting and blurring during the process of taking pictures, resulting in poor accuracy of the post-engraving detection of the rotor by taking pictures. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a rotor engraving detection device, which aims to solve the technical problem that due to the rotor always being in a moving state, the camera is prone to ghosting and blurring during the process of taking pictures, resulting in poor accuracy of the post-engraving detection of the rotor by taking pictures in the prior art.

[0007] (2) Technical Solution

[0008] To solve the above technical problems, the present utility model provides such a rotor engraving detection device. The rotor engraving detection device includes a mounting frame, and a rotor engraving machine main body and a detection frame fixed on both sides of the top surface of the mounting frame. A conveyor belt is installed on the mounting frame, and push blocks are equidistantly fixed on the outer wall of the conveyor belt. Slide rods are symmetrically fixed in the detection frame, and a moving frame is slidably sleeved between the two slide rods. A detection camera is fixedly embedded at the central position of the moving frame, and telescopic rods are slidably inserted at both ends of the moving frame, and the bottom ends of the telescopic rods abut against the push blocks.

[0009] When using the rotor engraving detection device of this technical solution, by providing push blocks on the outer wall of the conveyor belt, the moving frame equipped with the detection camera is fixed on the detection frame through the slide rods, and the spring at the bottom of the moving frame pushes the telescopic rods to protrude. When the push block pushes the rotor to move under the detection frame, the push block abuts against the side wall of the telescopic rod and drives the moving frame and the detection camera to slide synchronously. During the sliding process of the slide rods, the detection camera and the rotor are in a relatively static state, thus avoiding the double images that appear when photographing a dynamic rotor and improving the accuracy of photographing and detecting after rotor engraving; by symmetrically fixing positioning blocks at the top of the moving frame, and installing travel switches on both sides of the inner wall of the moving frame, during the movement of the moving frame and the telescopic rods, the positioning rods at the top of the telescopic rods move along the surface of the positioning blocks, and drive the telescopic rods to contract upward during the movement. When the moving frame contacts the travel switch, the telescopic rods are separated from the push blocks, and after separation, the travel switch activates the electric push rod. The electric push rod pushes the moving frame to the origin and then contracts and resets, facilitating the reset of the moved detection camera and improving the sustainability of the moving detection of the detection camera.

[0010] Preferably, drive shafts for driving the conveyor belt are embedded at both ends of the mounting frame, and a motor connected to the drive shaft is fixed on the side wall of the mounting frame.

[0011] Further, positioning rods are fixed at the tops of the two telescopic rods, and baffles are fixed at the bottoms of the two telescopic rods.

[0012] Furthermore, springs are sleeved on the telescopic rods, and the two ends of the springs abut against the baffles and the moving frame respectively.

[0013] Furthermore, positioning blocks are fixed on both sides of the top surface of the detection frame, both ends of the positioning rod are tightly connected to the top surface of the positioning block, and one ends of the two positioning blocks far from the rotor engraving machine main body are convexly arranged in an arc structure.

[0014] Furthermore, an electric push rod is fixedly installed on the outer wall of the detection frame, and the electric push rod abuts against the side wall of the moving frame.

[0015] Furthermore, travel switches are embedded and fixed on both sides of the inner wall of the detection frame. The travel switches are in contact with the side wall of the moving frame, and the travel switches are electrically connected to the electric push rod.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] In the present utility model, a push block is provided on the outer wall of the conveyor belt. The moving frame mounting the detection camera is fixed on the detection frame through a sliding rod. The spring at the bottom of the moving frame pushes the telescopic rod to protrude. When the push block pushes the rotor to move below the detection frame, the push block abuts against the side wall of the telescopic rod and drives the moving frame and the detection camera to slide synchronously. During the sliding process of the sliding rod, the detection camera and the rotor are in a relatively static state, thus avoiding the ghosting caused by photographing a dynamic rotor and improving the accuracy of photographing and detecting the rotor after engraving.

[0019] By symmetrically fixing positioning blocks at the top of the moving frame and installing travel switches on both sides of the inner wall of the moving frame, during the movement of the moving frame and the telescopic rod, the positioning rod at the top of the telescopic rod moves along the surface of the positioning block and drives the telescopic rod to contract upward during the movement. When the moving frame contacts the travel switch, the telescopic rod is separated from the push block, and after the separation, the travel switch activates the electric push rod. The electric push rod pushes the moving frame to the origin and then contracts and resets, facilitating the reset of the moved detection camera and improving the sustainability of the moving detection of the detection camera.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] This detailed implementation manner is a rotor engraving detection device, and its structural schematic diagram is as Figure 1 and Figure 2 shown. The rotor engraving detection device includes a mounting frame 1, and a rotor engraving machine main body 5 and a detection frame 2 fixed on both sides of the top surface of the mounting frame 1. A conveyor belt 6 is installed on the mounting frame. Push blocks 4 are fixedly arranged at equal intervals on the outer wall of the conveyor belt 6. Slide rods 8 are symmetrically fixed in the detection frame 2. A moving frame 13 is slidably sleeved between the two slide rods 8. A detection camera 12 is fixedly embedded at the central position of the moving frame 13. Telescopic rods 15 are slidably inserted at both ends of the moving frame 13. The bottom ends of the telescopic rods 15 abut against the push blocks 4.

[0028] Drive shafts 3 for driving the conveyor belt 6 are embedded at both ends of the mounting frame 1. A motor 7 connected to the drive shaft 3 is fixed on the side wall of the mounting frame 1. Positioning rods 11 are fixed at the top ends of the two telescopic rods 15. Baffles 14 are fixed at the bottom ends of the two telescopic rods 15. Springs 16 are sleeved on the telescopic rods 15. The two ends of the spring 16 abut against the baffle 14 and the moving frame 13 respectively. The spring 16 at the bottom end of the moving frame 13 pushes the telescopic rod 15 to protrude. When the push block 4 pushes the rotor to move below the detection frame 2, the push block 4 abuts against the side wall of the telescopic rod 15 and drives the moving frame 13 and the detection camera 12 to slide synchronously. During the sliding process of the slide rod 8, the detection camera 12 and the rotor are in a relatively static state, thus avoiding the double image caused by photographing a dynamic rotor.

[0029] As Figure 3 and Figure 4As shown in the figure, positioning blocks 10 are fixedly installed on both sides of the top surface of the detection frame 2. Both ends of the positioning rod 11 are tightly connected to the top surface of the positioning block 10. One end of each of the two positioning blocks 10 away from the rotor engraving machine main body 5 protrudes in an arc structure. An electric push rod 9 is fixedly installed on the outer wall of the detection frame 2. The electric push rod 9 abuts against the side wall of the moving frame 13. Travel switches 17 are embedded and fixed on both sides of the inner wall of the detection frame 2. The travel switches 17 abut against the side wall of the moving frame 13, and the travel switches 17 are electrically connected to the electric push rod 9. During the movement of the moving frame 13 and the telescopic rod 15, the positioning rod 11 at the top end of the telescopic rod 15 moves along the surface of the positioning block 10, and drives the telescopic rod 15 to contract upward during the movement. When the moving frame 13 contacts the travel switch 17, the telescopic rod 15 is separated from the push block 4, and after the separation, the travel switch 17 activates the electric push rod 9. The electric push rod 9 pushes the moving frame 13 to the origin and then contracts and resets.

[0030] The cross-sectional structure schematic diagram of the mounting frame 1 of the rotor engraving detection device is as Figure 2 shown, and its Figure 2 magnified schematic diagram of the structure at A therein is as Figure 3 shown, and its Figure 2 magnified schematic diagram of the structure at B therein is as Figure 4 shown.

[0031] Working principle: When using the rotor engraving detection device of this technical solution, start the motor 7 to drive the conveyor belt 6 to rotate. The spring 16 at the bottom end of the moving frame 13 pushes the telescopic rod 15 to protrude. When the push block 4 pushes the rotor to move below the detection frame 2, the push block 4 abuts against the side wall of the telescopic rod 15, and drives the moving frame 13 and the detection camera 12 to slide synchronously. During the sliding of the sliding rod 8, the detection camera 12 and the rotor are in a relatively static state, thus avoiding the double image problem that occurs when shooting a dynamic rotor. During the movement of the moving frame 13 and the telescopic rod 15, the positioning rod 11 at the top end of the telescopic rod 15 moves along the surface of the positioning block 10, and drives the telescopic rod 15 to contract upward during the movement. When the moving frame 13 contacts the travel switch 17, the telescopic rod 15 is separated from the push block 4, and after the separation, the travel switch 17 activates the electric push rod 9. The electric push rod 9 pushes the moving frame 13 to the origin and then contracts and resets, which is convenient for resetting the moved detection camera 12 and improves the sustainability of the moving detection of the detection camera 12 (in order to prevent the push block 4 on the top of the conveyor belt 6 from blocking during the reset process of the moving frame 13, another travel switch 17 closes the motor 7 during the reset process to make the conveyor belt 6 stationary, and the motor 7 is restarted using a button after the electric push rod 9 contracts).

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
