Description

Technical Field

[0001] The invention belongs to the technical field related to detection equipment processing, and specifically discloses a detection equipment for automobile fasteners. Background Art

[0002] There are many forms of abnormalities in automotive fasteners, such as fasteners being stretched due to excessive tension; fastener threads being crushed due to excessive pressure; fasteners being deformed due to shear stress; and fasteners gradually becoming abnormal due to long-term exposure to vibration. Fasteners are the most important connecting parts. If the strength of fasteners does not meet the requirements and they become loose or broken during driving, it will directly pose a huge threat to the driving safety of the vehicle. Bolts installed on cars are one of the essential parts of fasteners, so inspection is particularly important. When inspecting the existing long bolt rods, the length needs to be measured manually with a tape measure, which is time-consuming and laborious. The thread adaptability of the outer surface of the long bolt rod also needs to be inspected. Generally, the nut is manually screwed on the outside of the long bolt rod for inspection. This method is inefficient and not conducive to batch inspection. Therefore, we need to make improvements to this. Summary of the invention

A ruler 19 is fixedly installed on the upper edge of the bucket seat 34 away from the measuring assembly, and the spacing between the two ends of the ruler 19 is consistent with that of the silo 2.

[0019] The resistance rod assembly includes a frame plate 11 fixedly installed inside the silo 2, an L-shaped frame 12 is fixedly installed on the upper inner side of the frame plate 11, the inner side of the L-shaped frame 12 is connected to a clamping plate 8 through a fixedly clamped second cylinder 9, and a flat plate 13 is fixedly connected to the lower outer side of the frame plate 11. An infrared sensor for external use can be installed on the frame plate 11 and connected to the second cylinder 9. It can automatically clamp the long bolt rod, and can also be coordinated with manual assistance to ensure that the batches of long bolt rods sampled can be inspected one by one.

[0020] The rotating assembly includes a sleeve 18 fixedly installed inside the bucket seat 34, a fixed shaft 30 is rotatably installed inside the sleeve 18, and a friction sleeve 29 is equidistantly mounted on the outside of the fixed shaft 30 along the horizontal direction. The sleeve 18 can drive the fixed shaft 30 to rotate stably inside the bucket seat 34, and the friction sleeve 29 installed outside is used to enhance the contact surface with the long bolt rod, thereby assisting in driving the long bolt rod to rotate.

[0021] A first pulley assembly 31 is commonly provided on the outside of the two fixed shafts 30 and at one end away from the sleeve 18, a second pulley assembly 32 is provided on the outside of one of the fixed shafts 30 and near the front end of the first pulley assembly 31, and a second motor 33 is connected to the end of the second pulley assembly 32 away from the fixed shaft 30. The second motor 33 is fixedly mounted on the outer wall of one end of the bucket seat 34. The second motor 33 is connected to an external power source to drive the corresponding external second pulley assembly 32 to rotate, thereby allowing the corresponding fixed shaft 30 connected to the second pulley assembly 32 to rotate, and then driven by the first pulley assembly 31, the other fixed shaft 30 is driven to rotate, thereby the long bolt rod can be driven by the fixed shaft 30 to rotate inside the bucket seat 34, thereby assisting in the later detection of the threaded surface.

[0022] The measuring assembly includes a frame rod 4 respectively fixedly mounted on the upper edge of one side of the bucket seat 34, a sliding rod 5 is installed between the two frame rods 4, a screw rod 15 is installed between the two frame rods 4 and below the sliding rod 5 for common rotation, one end of the screw rod 15 passes through the outer side of one of the frame rods 4 and the end is connected to a first motor 14, the first motor 14 is fixedly mounted on the outer wall of the frame rod 4 at the corresponding position, a slide 6 is arranged outside the sliding rod 5 and the screw rod 15, the two frame rods 4 install the sliding rod 5 and the screw rod 15 on the upper edge of one side of the bucket seat 34, the sliding rod 5 cooperates to clamp the slide 6, and the screw rod 15 cooperates with the rotation of the first motor 14, so that the slide 6 can translate on the outer side of the sliding rod 5.

[0023] The slide 6 and the screw rod 15 are threadedly matched, and the slide 6 and the slide rod 5 are slidingly matched. The laser instrument 16 is fixedly installed on the inner side of one end of the slide 6. The position of the laser instrument 16 corresponds to that of the scale 19. The laser instrument 16 is a commonly used rangefinder and general length measuring equipment on the market, so no further details will be given. The slide 6 can automatically drive the laser instrument 16 to move in cooperation with the screw rod 15.

[0024] A threaded seat 17 is provided inside the bucket seat 34. Both sides of the threaded seat 17 are connected to the inner wall of the bucket seat 34 through symmetrically installed positioning bolts 35. A threaded hole is provided inside the threaded seat 17. The threaded seat 17 is installed inside the bucket seat 34 by means of the positioning bolts 35. The threaded hole provided inside can detect the screw groove of the threaded surface of the long bolt rod. The threaded surfaces of long bolt rods of different calibers are meshed later. The edge aperture of one end of the threaded seat 17 is larger, and a threaded surface suitable for the current detection caliber is processed deep inside. Therefore, after one end of the long bolt rod enters, it slowly rotates inside the threaded hole. The threaded seat 17 is fixedly arranged at one end of the bucket seat 34 under the connection of the positioning bolt 35. The threaded seat 17 of different calibers can be replaced for use according to the needs of detection in the later stage.

[0025] A first cylinder 7 is fixedly installed in the middle of the inner side of the slide 6, and a connecting seat 20 is fixedly installed at the telescopic end of the first cylinder 7. A cover plate 21 is fixedly connected to the bottom of the connecting seat 20. A plurality of balls 22 are installed at the lower inner side of the cover plate 21. The cover plate 21 can be clamped against the surface of the long bolt rod through the plurality of balls 22 at the lower side. When the long bolt rod is driven to rotate and advance into the inside of the threaded seat 17 at the back, one end of the long bolt rod will not be tilted. A clamping rod 23 is fixedly installed on one side of the cover plate 21, and a guide rod 24 is slidably inserted into the inner side of the clamping rod 23. A spring is sleeved on the outer side of the guide rod 24 and located below the clamping rod 23 25. The guide rod 24 can be stretched in height by the spring 25 when in use. When the cover plate 21 is attached to the outer surface of the long bolt rod, the guide rod 24 can be squeezed to the other end of the long bolt rod through the rubber sleeve 28 at the lower end. After being wrapped, the long bolt rod is pushed to move in the middle of the two fixed shafts 30. The bottom end of the guide rod 24 is fixedly connected to the fixing rod 26. A positioning seat 27 is fixedly installed on one side of the fixing rod 26. A rubber sleeve 28 is rotatably installed inside one side of the positioning seat 27. The rubber sleeve 28 can increase the contact resistance between the long bolt rod and the long bolt rod, and can fully contact with one end of the long bolt rod during the pushing process. It should be noted that two ends of the spring 25 are respectively connected to the outer walls of the clamping rod 23 and the fixing rod 26 at one end close to each other.

[0026] Working principle: the long bolt rod to be inspected can be placed inside the silo 2, and then under the cooperation of the blocking rod assembly and manual work, the corresponding long bolt rod is inspected in turn, and falls into the bucket seat 34 under the guidance of the flat plate 13 inside the silo 2. At this time, the first motor 14 drives the screw rod 15 to rotate, so that the slide 6 can drive the inner laser instrument 16 to move from one end of the long bolt rod to the other end, and then the length of the long bolt rod is accurately measured by using the laser instrument 16, and then the second motor 33 is started through the bucket seat 34 and the sleeve 18, so that the second motor 33 drives the second pulley assembly 32 to rotate, so that one of the fixed shafts 30 rotates, and then under the transmission of the first pulley assembly 31, the other fixed shaft 30 rotates, so that the long bolt rod can contact with the friction sleeve 29 on the outside of the fixed shaft 30 and rotate. Inside the bucket seat 34, the first cylinder 7 then moves to one end of the long bolt rod with the cooperation of the slide 6 and the screw 15. At this time, the first cylinder 7 drives the connecting seat 20 to move downward, so that the cover plate 21 below the connecting seat 20 is attached to the outer surface of the long bolt rod to engage the long bolt rod. At the same time, the clamping rod 23 installed on the outside of the cover plate 21 also drives the fixing rod 26 and the rubber sleeve 28 at the positioning seat 27 to move. During the movement, the guide rod 24 can facilitate the rubber sleeve 28 to contact with the end face of the long bolt rod under the elastic use of the spring 25. During the friction contact process, the two can move slowly with the slide 6, so that the long bolt rod can be slowly advanced to the threaded hole inside the threaded seat 17 during the rotation process, and then in the process of continuous rotation and advancement, the threads on the outside of the long screw rod and the threads deep in the threaded hole are ground with each other, thereby detecting the processing quality of the threads.
