Description

Technical Field

[0001] The utility model belongs to the field of automobile piston detection, in particular to a conveying mechanism for automobile piston surface defect detection. Background Art

[0002] The piston is a reciprocating component in the cylinder block of a car engine. The basic structure of the piston can be divided into the top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber form. Gasoline engines mostly use flat-top pistons, which have the advantage of a small heat absorption area. There are often various pits on the top of the diesel engine piston, and their specific shape, position and size must be adapted to the requirements of the mixture formation and combustion of the diesel engine. After the production of automobile pistons, they need to be inspected for surface defects.

[0003] At present, the utility model with the announcement number: CN217786878U discloses a constant-speed conveying mechanism for product surface defect detection, which relates to the field of defect detection technology. The constant-speed conveying mechanism for product surface defect detection includes a conveyor frame and a conveyor belt. The conveyor frame is provided with a symmetrical support frame, and a front baffle and a rear baffle perpendicular to the conveying direction of the conveyor belt are provided between the two support frames. The front baffle and the rear baffle are both slidably connected to the support frame, and a swing arm is provided between the front baffle and the rear baffle. The swing arm is fixed on the surface of the rotating shaft installed on the support frame, and one end of the rotating shaft is connected to the driving mechanism provided on the support frame. The utility model sets a front baffle and a rear baffle, and the front baffle and the rear baffle slide up and down in turn to intercept the product to be inspected in turn, so that the transmission distance of the product to be inspected on the conveyor belt is controllable, and is controlled by the front baffle and the rear baffle to ensure that the distance between two adjacent products to be inspected is equal, so as to achieve the purpose of constant-speed transmission of products.

[0004] The constant-speed conveying mechanism for surface defect detection has the beneficial effect of conveying products at a constant speed. However, when the front baffle blocks the product to be inspected, since the conveyor belt is in continuous transmission, the product to be inspected will generate friction with the conveyor belt while waiting and being restricted, thereby affecting the bottom of the product to be inspected and causing poor stability for the product to be inspected. Summary of the invention

[0005] The utility model aims to provide a conveying mechanism for detecting surface defects of automobile pistons, which has the advantages of ensuring the transmission usability of products, reducing the wear on the bottom of products, and having the function of stability in product detection.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a conveying mechanism for detecting surface defects of automobile pistons, comprising a shell, wherein an active roller and a driven roller are rotatably connected to the inside of the shell through bearings respectively, a conveyor belt sleeved on the surface of the driven roller is sleeved on the surface of the active roller, a surface profiler sleeved on the surface of the conveyor belt is fixedly installed inside the shell, a track is fixedly sleeved on the surface of the conveyor belt, a base is clamped on the top of the track, a clamping groove for matching the track clamping is opened at the bottom of the base, a plate body 1 and a plate body 2 are sequentially arranged on one side of the surface profiler, a fixing rod is fixedly installed on the top of the plate body 1 and the plate body 2, a clamping block is fixedly installed on the rear side of the fixing rod, a cross bar penetrating to both sides of the base is arranged at both ends of the inside of the base, a spring fixedly installed on one end of the cross bar is fixedly installed with the inside of the base, a vertical plate is fixedly installed on one end of the cross bar, a contact block is fixedly installed on the top of one side of the vertical plate, and a pull ring is fixedly installed on the other side of the vertical plate.

[0007] The above technical solution is adopted: when the surface defects of the automobile piston are detected, the piston is connected to the base first, and the base can be removed from the conveyor surface. By pulling the pull ring, the cross bar is driven to move laterally, so that the spring is stretched. At this time, the piston is placed between the two contact blocks, and then the strength of the pull ring is released to make the spring contract and drive the contact block close to the piston surface, so that the piston is firmly placed and the stability of the piston during transportation is improved. Then, when the base is placed on the conveyor surface, a card connection is formed between the card connection groove and the track. The operation of the rotating motor will drive the base to transfer. During the operation of the cylinder, the plate body 1 and the plate body 2 will move longitudinally respectively. During the rise of the plate body 1, the base is transferred into the surface profiler, so that the piston can detect surface defects. By setting the ball, the card connection groove and the track, the friction generated when the conveyor is continuously conveyed and the piston and the base are stationary is reduced, and at the same time, the service life of the conveyor is guaranteed and wear is reduced.

[0008] The utility model is further configured that one end of the active roller penetrates to the rear side of the shell, a rotary motor is fixedly installed on the rear side of the shell, and the output end of the rotary motor is fixedly sleeved with the active roller through a coupling.

[0010] The utility model is further configured that a ball bearing which is fixedly connected to the base and in contact with the track is arranged inside the clamping groove.

[0011] The above technical solution is adopted: the friction between the track and the base is reduced by the ball bearings.

[0012] The utility model is further configured that the number of the rails and the number of the clamping slots are both two.

[0013] The above technical solution is adopted: the connectivity and guidance between the conveyor belt and the base are increased by two methods.

[0014] The utility model is further configured such that a connecting rod penetrating to the rear side of the shell is rotatably connected to the inside of the shell through a bearing, support rods are fixedly installed on both sides of the connecting rod, and a through groove for cooperating with a clamping block is provided inside the support rod.

[0015] By adopting the above technical solution, the support rod is driven to be adjusted horizontally through the rotation of the connecting rod, and the clamping block and the through groove form a clamping connection between the support rod and the plate body one and the plate body two.

[0016] The utility model is further configured such that a rod body is fixedly installed at the bottom of the rear side of the connecting rod, a ring is slidably sleeved on the surface of the rod body, one end of the ring is provided with a cylinder fixedly connected to the rear side of the shell, and the output end of the cylinder is rotatably connected to one side of the ring through a rotating shaft.

[0017] By adopting the above technical solution, the operation of the cylinder will drive the collar to move laterally, and during the movement of the collar, the rod body will be driven to change its angle around the connecting rod, thereby causing the connecting rod to rotate.

[0018] The utility model is further configured that sliding blocks are fixedly mounted on the surfaces and rear sides of the plate body 1 and the plate body 2, and a sliding groove for cooperating with the sliding blocks is provided inside the shell.

[0019] The above technical solution is adopted: the slide block and the slide groove cooperate with the plate body one and the plate body two for guiding.

[0020] The utility model is further configured that both sides of the shell surface are rotatably connected with a door body through hinges, a visual window is embedded in the surface of the door body, and a handle is fixedly installed on one side of the door body surface.

[0021] By adopting the above technical solution, the inside of the shell can be easily operated through the door body, the visual window can facilitate viewing of the inside of the shell, and the handle can facilitate opening and use of the door body.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. When the base is placed on the surface of the conveyor belt, the clamping groove and the track are clamped together. The operation of the rotating motor will drive the base to transfer. During the operation of the cylinder, the plate body 1 and the plate body 2 will be driven to move longitudinally respectively. During the rise of the plate body 1, the base is transferred into the surface profiler, so that the piston can detect surface defects. Through the arrangement of the ball bearing, the clamping groove and the track, the friction generated when the piston and the base are stationary during the continuous transmission of the conveyor belt is reduced, and the service life of the conveyor belt is also guaranteed, and the wear is reduced;

[0024] 2. When the utility model detects surface defects on automobile pistons, the piston is preferentially connected to the base, and the base can be removed from the surface of the conveyor belt. By pulling the pull ring, the cross bar is driven to move laterally, so that the spring is stretched.

A clamping block 14 is fixedly installed on the rear side. When the base 6 is placed on the surface of the conveyor belt 5, a clamping connection is formed between the clamping groove 20 and the track 7. The operation of the rotating motor 8 will drive the base 6 to transfer. During the operation of the cylinder 17, the plate body 10 and the plate body 2 11 will be driven to move longitudinally respectively. During the rising of the plate body 10, the base 6 is transferred into the surface profiler 2, so that the piston can detect surface defects. Through the arrangement of the ball 21, the clamping groove 20 and the track 7, the friction generated when the piston and the base 6 are stationary during the continuous transmission of the conveyor belt 5 is reduced, thereby ensuring the service life of the conveyor belt 5 and reducing wear.

[0034] refer to Figure 1 One end of the active roller 3 passes through the rear side of the shell 1, and a rotating motor 8 is fixedly installed on the rear side of the shell 1. The output end of the rotating motor 8 is fixedly connected with the active roller 3 through a coupling, and the operation of the rotating motor 8 will drive the active roller 3 to rotate.

[0035] refer to Figure 5 A ball 21 fixedly connected to the base 6 and in contact with the track 7 is provided inside the clamping groove 20 , and the friction between the track 7 and the base 6 is reduced by the ball 21 .

[0036] refer to Figure 5 The number of the rails 7 and the number of the engaging grooves 20 are both two, and the connectivity and guiding properties of the conveyor belt 5 and the base 6 are increased by the two.

[0037] refer to Figure 3 The inside of the shell 1 is rotatably connected with a connecting rod 15 that penetrates to the rear side of the shell 1 through a bearing. Support rods 9 are fixedly installed on both sides of the connecting rod 15. A through groove 12 is opened inside the support rod 9 to cooperate with the clamping block 14 for clamping. The rotation of the connecting rod 15 will drive the support rod 9 to be horizontally adjusted, and the clamping block 14 and the through groove 12 will form a clamping connection between the support rod 9 and the plate body 10 and the plate body 2 11.

[0038] refer to Figure 4 A rod body 29 is fixedly installed at the bottom of the rear side of the connecting rod 15, and a ring 16 is slidably sleeved on the surface of the rod body 29. One end of the ring 16 is provided with a cylinder 17 fixedly connected to the rear side of the shell 1. The output end of the cylinder 17 is rotatably connected to one side of the ring 16 through a rotating shaft. The operation of the cylinder 17 will drive the ring 16 to move laterally, and during the movement of the ring 16, the rod body 29 will be driven to change its angle around the connecting rod 15, thereby causing the connecting rod 15 to rotate.

[0039] refer to Figure 3 Slide blocks 19 are fixedly installed on the surface and rear side of the plate body 10 and the plate body 2 11, and a slide groove 18 for cooperating with the slide block 19 is opened inside the shell 1. The slide block 19 and the slide groove 18 cooperate with the plate body 10 and the plate body 2 11 for guiding.

[0040] The use process is briefly described as follows: when the base 6 is placed on the surface of the conveyor belt 5, and a clamping connection is formed between the clamping groove 20 and the track 7, the operation of the rotating motor 8 will drive the active roller 3 to rotate, and the driven roller 4 will be driven to rotate through the setting of the conveyor belt 5, thereby transmitting the base 6 on the surface of the conveyor belt 5. The conveyor belt 5 and the base 6 are in a relatively static state. In the absence of external force, the base 6 cannot rotate. With the transmission of the base 6, the operation of the cylinder 17 will drive the collar 16 to move laterally, and in the movement of the collar 16, the rod body 29 will be driven to change the angle around the connecting rod 15, so that the connecting rod 15 is rotated. The rotation of the connecting rod 15 will drive the support rod 9 to adjust horizontally, and the clamping block 14 and the through groove 12 will form a clamping connection between the support rod 9 and the plate body 10 and the plate body 2 11, so that the plate body 10 and the plate body 10 are connected. The plate body 11 has respective longitudinal movements, and the movement directions are opposite. When the plate body 10 is raised, the base 6 is transmitted into the surface profiler 2, so that the piston detects surface defects, wherein the contact block 24 and the piston surface do not affect the optical illumination effect. The plate body 11 limits the base 6, so that the base 6 and the piston on one side of the plate body 11 are both pistons to be detected, and when the plate body 11 blocks the base 6, the ball 21 is rotated by the external force, and the snap-in groove 20 is snap-moved on the surface of the track 7. The quantitative detection effect of the detection device is increased by the arrangement of the plate body 10 and the plate body 11. At the same time, the friction generated when the piston and the base 6 are stationary during the continuous transmission of the conveyor belt 5 is reduced by the arrangement of the ball 21, the snap-in groove 20 and the track 7, and the service life of the conveyor belt 5 is also guaranteed, and the wear is reduced.

When the surface defects of the automobile piston are detected, the piston is preferentially connected to the base 6, and the base 6 can be removed from the surface of the conveyor belt 5. By pulling the pull ring 25, the cross bar 22 is driven to move laterally, so that the spring 30 is stretched. At this time, the piston is placed between the two contact blocks 24, and then the strength of the pull ring 25 is released, so that the spring 30 contracts and drives the contact block 24 to approach the piston surface, so that the piston is firmly placed, and the stability of the piston during transportation is improved.
