DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: an automatic detection device for the size of a threaded hole of a vehicle wheel hub, comprising a base 1 and a wheel hub member 5, wherein the top of the base 1 is connected to a rotating disk 2 by rotation, a detection component 4 is arranged at the axis of one side of the rotating disk 2, and a clamping block 3 for clamping and fixing the wheel hub member 5 is arranged on the outer side of the detection component 4, such a design enables the wheel hub member 5 to be accurately positioned and detected;

[0030] The surface of the hub member 5 is specially designed with a positioning hole 51 and a threaded hole 52. The positioning hole 51 is located at the axis of the hub member 5, and the threaded hole 52 is located around the positioning hole 51. This design allows the detection component 4 to accurately detect and process the size of the threaded hole 52 to ensure that the size of the threaded hole 52 meets the predetermined technical requirements.

[0031] The detection component 4 includes a positioning column 41 fixedly installed at the axis of the rotating disk 2. The specifications of the positioning column 41 are completely matched with the specifications of the positioning hole 51, ensuring the accuracy of positioning. The outer wall of the positioning column 41 is fixedly connected with a mounting frame 42. The mounting frame 42 is rotatably connected with a control rod 43. One end of the control rod 43 is fixedly connected with a first gear 44. The upper and lower ends of the first gear 44 are meshed with a gear rod 45 slidably installed on the mounting frame 42. The outer end of the gear rod 45 is fixedly connected with a push rod 46 for detecting the diameter of the threaded hole 52. When the control rod 43 rotates, the first gear 44 will drive the upper and lower meshing gear rods 45 to move synchronously to both sides or to the middle, thereby causing the two gear rods 45 to move synchronously to both sides or to the middle. This linkage mechanism allows the two push rods 46 to detect and process whether the size of the threaded hole 52 of the hub member 5 is qualified, thereby ensuring the quality of the product.

[0032] In the present invention, the outer wall of the positioning column 41 is connected to an outer gear ring 47 by rotation, and the outer end of the outer gear ring 47 is meshed with a second gear 48 fixedly installed at the end of the control rod 43. An inner gear ring 49 is fixedly connected to the side wall of the outer gear ring 47. At the same time, the outer wall of the positioning column 41 is also connected to a rotating rod 410 by rotation. A forward and reverse motor 412 fixedly installed on the rotating disk 2 is provided at one end of the rotating rod 410, and a third gear 411 meshed with the inner gear ring 49 is fixedly connected to the other end of the rotating rod 410. The rotating rod 410 is driven by the forward and reverse motor 412. 410 and the third gear 411 can rotate forward or reverse. When the third gear 411 rotates, it will drive the inner gear ring 49 and the outer gear ring 47 meshing therewith to rotate forward or reverse synchronously. As the outer gear ring 47 rotates, the second gear 48 meshing therewith and the control rod 43 and the first gear 44 will also rotate forward or reverse synchronously. Such rotation enables the first gear 44 to drive the upper and lower meshing gear rods 45 to move synchronously to both sides or to the middle. Finally, through this synchronous movement, the two gear rods 45 can detect and process the size of the threaded hole 52 of the hub member 5 to ensure whether it meets the standard.

[0033] In an embodiment of the present invention, through the precise drive of the forward and reverse motor 412, the rotating rod 410 and the third gear 411 can realize precise forward or reverse rotation, and the third gear 411 is tightly meshed with the inner ring gear 49 and the outer ring gear 47, ensuring that these components can synchronously perform precise forward or reverse rotation. As the outer ring gear 47 rotates, it will further drive the second gear 48 and the control rod 43 and the first gear 44 that are tightly meshed therewith, so that these components can also synchronously perform precise forward or reverse rotation. The effect of this synchronous rotation is that the first gear 44 can drive the gear rod 45 that is tightly meshed up and down to move synchronously to both sides or to the middle. Through this precise movement, the two gear rods 45 can work together to accurately detect and process the size of the threaded hole 52 of the hub member 5 to ensure whether it meets the specified standards, thereby ensuring the efficient and precise operation of the entire mechanical system.

[0034] Embodiment 2: Combination Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, on the basis of the first embodiment, the top of the control rod 43 is installed in a sliding manner through the support 427. This installation method allows the control rod 43 to slide freely forward and backward on the support 427. The movable rod 413 is connected to the control rod 43. One end of the movable rod 413 is fixedly installed on the adjustment block 414 on the gear rod 45, ensuring a stable connection between the movable rod 413 and the adjustment block 414, and the other end of the movable rod 413 is fixedly installed in the sleeve 417 on the rotating disk 2. This design enables the movable rod 413 to move accordingly with the rotation of the rotating disk 2. The surface of the movable rod 413 is also fixedly connected with A limit block 418 is located between the supports 427, and a damping spring 419 is provided on one side of the limit block 418 and is sleeved on the movable rod 413. Under the push of the elastic force of the damping spring 419, the limit block 418 and the movable rod 413 move toward one side of the adjustment block 414, so that the end of the movable rod 413 can slide and fit on the surface of the adjustment block 414, ensuring the close contact between the movable rod 413 and the adjustment block 414. When the movable rod 413 slides on the inclined area 416, it can push the movable rod 413 to move toward one side of the rotating disk 2, thereby driving the limit block 418 to move synchronously and compressing the damping spring 419;

[0035] A straight area 415 is provided at one end of the adjusting block 414 close to the movable rod 413, and inclined areas 416 are provided on both sides of the straight area 415. When the straight area 415 is located at the end of the movable rod 413 and moves, the threaded hole 52 of the hub member 5 is in a qualified state, which means that the size of the threaded hole 52 meets the predetermined standard, thereby ensuring the quality of the hub member 5. On the contrary, when the inclined area 416 is located at the end of the movable rod 413 and moves, the threaded hole 52 of the hub member 5 is in an unqualified state, indicating that the size of the threaded hole 52 exceeds the predetermined standard range, which will prompt the operator to further check and adjust the hub member 5.

[0036] Two fixed copper sheets 421 are respectively arranged on one side of the inner cavity of the sleeve 417, and the two fixed copper sheets 421 are symmetrically arranged to ensure the balance and stability of the circuit. The top of the movable rod 413 is fixedly connected with a connecting copper sheet 420, and the connecting copper sheet 420 is located on one side of the fixed copper sheet 421. This design enables the connecting copper sheet 420 to form contact with the fixed copper sheet 421. An alarm light 424 is arranged on the top of the sleeve 417, and the alarm light 424 is connected to the two fixed copper sheets 421 through a wire 425. A power supply is also arranged on the wire 425. When the movable rod 413 is located at the straight area 415, the connecting copper sheet 420 is located on the fixed copper sheet 421. When the movable rod 413 is on one side of the plate 421, the alarm light 424 will not light up, ensuring the normal operation of the system; however, when the movable rod 413 moves to the position of the inclined area 416, the connecting copper plate 420 will contact the two fixed copper plates 421, so that the connecting copper plate 420, the two fixed copper plates 421, the wire 425, the power supply and the alarm light 424 form a complete circuit, so that the power supply can provide electrical energy, so that the alarm light 424 performs alarm processing, and through the alarm processing of the alarm light 424, the size of the threaded hole 52 of the hub part 5 can be effectively detected and processed to ensure that it meets the quality standards, thereby ensuring the quality and safety of the product.

[0037] In an embodiment of the present invention, when the movable rod 413 is exactly in the position of the straight zone 415, the connecting copper sheet 420 will be on the side of the fixed copper sheet 421. This specific physical position relationship ensures that the alarm light 424 will not be activated, so the alarm light 424 will not send out any warning signal. However, once the movable rod 413 moves to the position of the inclined zone 416, the situation will change. At this time, the connecting copper sheet 420 will contact the two fixed copper sheets 421 to form a closed circuit. This closed circuit includes the connecting copper sheet 420, two fixed copper sheets 421, the wire 425, the power supply and the alarm light 424. When the circuit is closed, the power supply starts to supply electrical energy to the circuit, causing the alarm light 424 to be activated and start to send out a warning signal. Through the alarm processing mechanism of the alarm light 424, the size of the threaded hole 52 of the hub component 5 can be effectively and accurately detected and monitored.

[0038] Example 3: Combination Figure 7 As shown, on the basis of the second embodiment, an electric slide rail 25 is specially designed and installed at the inner end of the rotating disk 2. This innovative design enables the clamping block 3 to achieve smooth sliding movement through the electric slide rail 25, and this sliding installation method ensures the stability and flexibility of the clamping block 3 on the rotating disk 2.

[0039] In an embodiment of the present invention, during the process of the hub member 5 being accurately installed on the positioning column 41 through its positioning hole 51, it is ensured that the threaded hole 52 and the control rod 43 accurately correspond to each other in position. After this process is completed, the gear rod 45 and the push rod 46 are immediately guided into the threaded hole 52 of the hub member 5. Subsequently, through the precise control of the electric slide rail 25, the clamping block 3 is driven to move inward. This action enables the four groups of clamping blocks 3 to tightly clamp and position the hub member 5, thereby greatly improving the convenience and accuracy of detecting and processing the threaded hole 52.

[0040] Working principle of vehicle wheel hub thread hole size automatic detection equipment:

[0041] Step 1: When the hub member 5 is installed on the positioning column 41 through the positioning hole 51, ensure that the positions of the threaded hole 52 and the control rod 43 correspond to each other, so that the gear rod 45 and the push rod 46 can smoothly enter the threaded hole 52. Then, the electric slide rail 25 is used to control the clamping block 3 to move inward, so that the four groups of clamping blocks 3 clamp and position the hub member 5, thereby facilitating the subsequent detection of the threaded hole 52.

[0042] Step 2: Driven by the forward and reverse motor 412, the rotating rod 410 and the third gear 411 start to rotate. The rotation of the third gear 411 will drive the inner gear ring 49 and the outer gear ring 47 meshing therewith to rotate. With the rotation of the outer gear ring 47, the second gear 48 meshing therewith, the control rod 43, and the first gear 44 will also rotate synchronously. The rotation of the first gear 44 will drive the upper and lower meshing gear rods 45 to move synchronously, thereby causing the two gear rods 45 to move synchronously to both sides. When the gear rod 45 moves to an appropriate position, the two push rods 46 contact the inner wall of the threaded hole 52. The two push rods 46 are used to detect whether the size of the threaded hole 52 of the hub member 5 is qualified.

[0043] Step three, when the movable rod 413 is exactly in the position of the straight zone 415, the connecting copper sheet 420 will be on the side of the fixed copper sheet 421. This specific physical position relationship ensures that the alarm light 424 will not be activated, so the alarm light 424 will not send out any warning signal. However, once the movable rod 413 moves to the position of the inclined zone 416, the situation will change. At this time, the connecting copper sheet 420 will contact the two fixed copper sheets 421 to form a closed circuit. This closed circuit includes the connecting copper sheet 420, two fixed copper sheets 421, the wire 425, the power supply and the alarm light 424. When the circuit is closed, the power supply starts to supply electrical energy to the circuit, causing the alarm light 424 to be activated and start to send out a warning signal. Through the alarm processing mechanism of the alarm light 424, the size of the threaded hole 52 of the hub component 5 can be effectively and accurately detected and monitored to ensure that the quality of the product meets the standards.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
