Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a gear precision detection device applied in the field of detection devices. Background Art

[0002] A vision-based gear accuracy tester utilizes computer vision technology to inspect gear accuracy. It captures images of the gears through an image acquisition system and then analyzes them using image processing algorithms to determine whether the gears meet various accuracy requirements. This device enables high-precision and efficient gear accuracy testing, making it a crucial tool in modern machinery manufacturing and quality control.

[0003] Chinese patent CN212674065U discloses a height-adjustable integrated visual inspection device. The device includes a height adjustment assembly and several CCD cameras. The height adjustment assembly comprises an adjustment block, an adjustment rod, a locking rod, and intermeshing gears and racks. The adjustment block is threadedly connected to the front of the rear connecting plate of the stand. This device allows for rapid and high-precision adjustment of the inspection height, making it suitable for semi-automatic and full-scale inspection of various parts, thus preventing missed inspections of large quantities of parts.

[0004] After the gear precision detection device is completed, it can be collected in the material frame using a blowing device. During the blowing process, if the inner wall of the material frame is made of hard material and there is no buffer, once the gear comes into contact with it, a hard collision is likely to occur. Therefore, it is necessary to design a gear precision detection device with a material discharge buffer mechanism to solve the above problem. Summary of the Invention

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that after the gear precision detection device is completed, it can be collected in a material frame using a blowing device. During the blowing process, if the inner wall of the material frame is made of hard material and there is no buffer, once the gear comes into contact with it, a hard collision is likely to occur.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] In the above-mentioned gear precision detection device, when the material storage vertical frame accepts the gear parts, this scheme can set up multiple material receiving turntables that rotate through the rotating shaft cross piece to provide buffering force for the blowing path of the gear parts, so that the gear parts can gently contact the inner wall of the material receiving turntable when entering the material receiving turntable, avoiding damage to the tooth surface of the gear parts, thereby ensuring that the accuracy and appearance quality of the gear parts are not damaged, reducing quality problems caused by collisions, thereby reducing the defective rate and improving production efficiency.

[0008] As a further improvement of the present application, a plurality of gear parts are provided on the upper end of the detection turntable, and the gear parts extend into the corresponding material storage vertical frames.

[0009] As a further improvement of the present application, the gear member is engaged with a position between the two arc-shaped inner clips, and a wear-resistant inner liner layer is fixedly connected between the two arc-shaped inner clips.

[0010] As a further improvement of the present application, an inner slot is provided on the inner wall of the separating material frame on one side close to the rotating shaft cross piece, and an electric push rod is fixedly connected to the inner side wall of the inner slot.

[0011] As another improvement of the present application, the output end of the electric push rod is fixedly connected to a rubber material-receiving vertical rod, and the rubber material-receiving vertical rod extends out of the outer side of the inner slot.

[0012] As another improved supplement of the present application, the rubber stopper vertical rod is located between the two buffer flexible inner layers, and the rubber stopper vertical rod is in contact with the gear member.

[0013] As another improved supplement of the present application, a discharge guide channel is provided at the lower end of the material storage vertical frame, and the discharge guide channel is interconnected with the corresponding partition material frame.

[0014] In summary, in this solution, when the material storage vertical frame accepts the gear parts, multiple material receiving turntables that are rotated by the rotating shaft cross piece can be set inside it, and the opening position of the partition frame in the material receiving turntable corresponds to the blowing direction of the gear parts. When the strong airflow pushes the gear parts vertically into the partition frame, the gear parts are transferred to between the two innermost arc-shaped inner clamps of the partition frame. The spring between the two arc-shaped inner clamps can clamp and limit the gear parts, and make the buffering flexible inner layer provide buffering force for the blowing path of the gear parts. The gear parts are received by a separate partition frame during unloading. When the partition frame rotates to the opening position above the discharge guide channel, the gear parts in the corresponding partition frame can automatically fall into the discharge guide channel due to gravity and move towards the next step area or storage. This method can make the gear parts gently contact the inner wall of the material receiving turntable when entering the material receiving turntable, avoiding damage to the tooth surface of the gear parts, thereby ensuring the accuracy and appearance quality of the gear parts are not damaged, reducing quality problems caused by collisions, thereby reducing the defective rate and improving production efficiency.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-4 、 Figure 7 A gear precision detection device is shown, comprising a detection turntable 1 at the output end of a driving shaft 17, a supporting crossbar 2 being provided on the right side of the upper end of the detection turntable 1, a visual detection camera 3 being fixedly connected to the lower end of the supporting crossbar 2 on the side close to the detection turntable 1, the front end of the supporting crossbar 2 being fixedly connected to two material storage vertical frames 4, one end of the supporting crossbar 2 close to the material storage vertical frame 4 being fixedly connected to an extended crossbar 6 located above the detection turntable 1, and air blowing nozzles 7 being symmetrically fixedly connected to the left and right sides of one end of the extended crossbar 6 close to the material storage vertical frame 4, and the two air blowing nozzles 7 are respectively fixed to the left and right sides of the two ends of the extended crossbar 6 close to the material storage vertical frame 4. The corresponding openings of the material storage vertical frames 4 correspond to each other. The inner end of the material storage vertical frame 4 is installed with a material receiving turntable 5, and the middle part of the material receiving turntable 5 is installed with a rotating shaft cross piece 8. The rotating shaft cross piece 8 is externally connected to a motor, and the outer end of the rotating shaft cross piece 8 is fixedly connected to a plurality of partition material frames 9. The plurality of partition material frames 9 are arranged in a ring shape and equidistantly. The inner side wall of the partition material frame 9 is fixedly connected with a buffering flexible inner layer 10, and the end of the buffering flexible inner layer 10 away from the inner side wall of the partition material frame 9 is fixedly connected with a plurality of springs 11, and the corresponding outer sides of the plurality of springs 11 are fixedly connected with an arc-shaped inner clip 12.

[0027] Figure 1-4 、 Figure 7 It is shown that several gear parts are provided at the upper end of the detection turntable 1, which extend into the corresponding material storage vertical frame 4, and are engaged with the position between the two arc-shaped inner clips 12. A wear-resistant inner liner layer 18 is fixedly connected between the two arc-shaped inner clips 12. A discharge guide channel 14 is provided at the lower end of the material storage vertical frame 4, and the discharge guide channel 14 is interconnected with the corresponding partition frame 9.

[0028] Figure 1-4 、 Figure 7It is shown that in this scheme, when the gear parts rotate to the detection area along with the detection turntable 1, the visual detection camera 3 collects images of the gear parts under the control of the trigger signal. For the gear parts judged to be qualified, the detection turntable 1 will transport them to the left storage vertical frame 4 and blow the gear parts into it through the left air blowing nozzle 7. For the unqualified gear parts, the detection turntable 1 will transport them to the right storage vertical frame 4 and blow the gear parts into it through the right air blowing nozzle 7, and sort them into different storage vertical frames 4 for rework, scrapping or other processing. When the storage vertical frame 4 receives the gear parts, a plurality of material receiving turntables 5 that are rotated by the rotating shaft cross piece 8 can be set therein. The opening positions of the separation material frames 9 in the material receiving turntable 5 have the blowing directions of the gear parts corresponding to each other. When the strong airflow vertically separates the gear parts into the material frames 9, the gear parts are transferred to between the two innermost arc-shaped inner clips 12 of the separating material frame 9, and the spring 11 between the two arc-shaped inner clips 12 can clamp and limit the gear parts, and make the buffer flexible inner layer 10 provide buffering force for the blowing path of the gear parts. The gear parts are received by a separate separating material frame 9 during unloading. When the separating material frame 9 rotates to the opening position above the discharge guide channel 14, the gear parts in the corresponding separating material frame 9 can automatically fall into the discharge guide channel 14 due to gravity and move toward the next step area or storage. This method can make the gear parts gently contact the inner wall of the receiving turntable 5 when entering the receiving turntable 5, avoiding damage to the tooth surface of the gear parts, thereby ensuring the accuracy and appearance quality of the gear parts are not damaged, reducing quality problems caused by collisions, thereby reducing the defective rate and improving production efficiency.

[0029] Second implementation method:

[0030] Figure 5-6 The present invention provides a gear precision detection device, in which an inner wall of the separating material frame 9 near the rotating shaft cross piece 8 is provided with an inner slot 13, and an electric push rod 15 is fixedly connected to the inner wall of the inner slot 13, and an output end of the electric push rod 15 is fixedly connected to a rubber material abutment vertical rod 16, which extends out of the outer side of the inner slot 13 and is located between the two buffer flexible inner layers 10. The rubber material abutment vertical rod 16 contacts the gear part, and when the separating material frame 9 rotates to above the discharge guide channel 14, there may be a state in which the gear part and the arc-shaped inner clip 12 in the separating material frame 9 are too tightly engaged, resulting in poor unloading condition. Therefore, when the separating material frame 9 is just above the discharge guide channel 14 in which the separating material frame 9 rotates, the rubber material abutment vertical rod 16 in the electric push rod 15 therein can be used to push out the outer side of the inner slot 13, providing thrust for the gear part, so that it falls more smoothly into the discharge guide channel 14, and at the same time makes the material receiving process of the next gear part more stable.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
