Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a device for automatic flatness testing. Background Technology

[0002] Sintered ring parts are circular ring-shaped components manufactured using powder metallurgy processes. They are widely used in various fields such as machinery, automobiles, and aerospace. Due to their unique manufacturing process and performance characteristics, these parts play an irreplaceable role in many applications. Therefore, sintered ring parts need to undergo flatness testing to ensure that their surface flatness meets design and application requirements. This not only affects the assembly accuracy of the parts but may also have a significant impact on the performance of the entire system.

[0003] Traditional flatness inspection usually relies on manual tools such as dial indicators and levels. These tools require operators to measure each part one by one and record the data, which is very time-consuming. Operators not only need to stay focused for a long time to ensure the accuracy of each measurement, but also need to frequently adjust the position and angle of the measuring equipment, which greatly increases the workload. The measurement results of different batches or the same operator at different times may fluctuate greatly, affecting the consistency of product quality. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic flatness detection device, including an operating table, on which a turntable assembly and a detection assembly are mounted;

[0005] The turntable assembly includes a support plate fixed on the operating table. The edge of the support plate has a raised edge with two large and one small openings. The inner side of the support plate is rotatably connected to a turntable, and the outer side of the turntable has multiple semi-circular slots. The bottom of the operating table is also equipped with a belt drive device to drive the turntable to rotate.

[0006] The detection assembly includes a support frame, with multiple probe detection devices mounted on the top of one end of the support frame above the turntable, and a pusher mounted on one side. The pusher end of the pusher is fixed with a small opening that can pass through the protruding edge and extend to a top clamping block on the support plate.

[0007] Furthermore, a positioning cylinder is also installed on the table surface of the operating table, located below the support plate. The piston rod of the positioning cylinder passes through the support plate, and the turntable has multiple positioning holes that are adapted to the piston rod of the positioning cylinder.

[0008] Furthermore, the pushing part includes a top clamping cylinder mounted on a support frame and two guide rods passing through it. The piston rod of the top clamping cylinder and the guide rods are both fixed to the top clamping block.

[0009] Furthermore, a feeding conveyor and a feeding assembly are installed on the left side of the operating table, and a discharging assembly and a discharging conveyor that docks with the support plate are installed on the right side. The feeding conveyor is docked with the support plate through the feeding assembly.

[0010] Furthermore, the feeding assembly includes a stand and a receiving platform fixed on the operating table. A push cylinder is installed on one side of the stand, and a push frame is fixed to the piston rod of the push cylinder. A lower push cylinder is installed on the top of the push frame, and a lever connected to the lower push cylinder is slidably connected to the side wall. A rubber pad is fixed on one side of the lever.

[0011] Furthermore, the receiving platform is connected to the support plate and the feeding conveyor platform. Two side platforms are fixed on the table surface of the operating platform, which are distributed on both sides of the receiving platform. Clamping cylinders are installed on the side platforms. Clamping plates are fixed to the piston rods of the clamping cylinders. The bottom of the clamping plates is in contact with the table surface of the receiving platform. The end of the clamping plates in contact with the receiving platform is conical.

[0013] Furthermore, the operating platform is also fixed with a discharge channel that is connected to the side of the discharge conveyor platform, and a side plate is fixed on the side of the operating platform opposite to the discharge channel. An ejector cylinder is installed on the side plate and two columns are inserted through it. The piston rod of the ejector cylinder is fixed with an ejector block connected to the columns.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This automatic flatness inspection device, through the cooperation of the feeding conveyor and the feeding component, pushes the product onto the support plate. Then, the turntable is driven by a belt drive to rotate, thus pushing the product under the probe inspection device. The pushing part then drives the top clamp block to fix the product. The flatness is then inspected by the probe inspection device. After the inspection is completed, the pushing part retracts, and the turntable continues to rotate, thereby transferring the product to dock with the unloading conveyor. The unloading component completes the unloading and sorting operations. Therefore, the device can improve the efficiency, accuracy and consistency of inspection through automation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The device for automatic flatness detection in this embodiment includes an operating table 1, and a feeding conveyor 6, a feeding assembly 4, a turntable assembly 2, a detection assembly 3, a discharging conveyor 7, a discharging assembly 5, and a discharging channel installed sequentially from left to right. The feeding conveyor 6 is connected to the left side of the turntable assembly 2 through the feeding assembly 4. The detection assembly 3 is located on the side of the turntable assembly 2, and its detection end is located above the turntable assembly 2. The discharging conveyor 7 is connected to the right side of the turntable assembly 2. The discharging channel is opposite to the discharging assembly 5 and is connected to the discharging conveyor 7.

[0024] In the above structure, the product is conveyed to the feeding assembly via the feeding conveyor, and then the feeding assembly moves the product to the turntable assembly. The turntable assembly rotates the product until it is located below the detection assembly to complete the detection operation. After the detection is completed, the turntable assembly rotates again so that the product is facing the unloading conveyor, and then the unloading assembly moves the product out, thus completing the unloading operation. This achieves automated loading and unloading, and the product is conveyed to the detection assembly for detection, thereby effectively improving the efficiency, accuracy and consistency of the detection.

[0025] like Figure 4 The feeding assembly 4 includes a stand 41 fixed on the operating table 1 and a receiving platform 47 that connects to the feeding conveyor 7 and the turntable assembly 2. A push cylinder 42 is installed on the back of the stand 41. A push frame 43 is fixed to the piston rod of the push cylinder 42. A lower push cylinder 44 is installed on the top of the push frame 43, and a lever 45 is slidably connected to the left side. The lower left end of the lever 45 is L-shaped, and the concave part is arc-shaped. A matching rubber pad 46 is fixed to the lower left end of the lever 45. The product is conveyed to the receiving platform by the feeding conveyor and then the lower push cylinder drives the lever to descend into the inner ring of the product. The push cylinder drives the push frame to push out until the product is embedded in the rubber pad. The side of the rubber pad and the lever that is in contact with the inner ring of the product is arc-shaped to fit the product. By continuously pushing out by the push cylinder, the product can be pushed onto the turntable assembly to complete the feeding operation.

[0026] Further explanation: The top of the operating table 1 is fixed with side platforms 48 distributed on both the front and rear sides of the receiving platform 47. The top of each side platform 48 is equipped with opposing clamping cylinders 49. The piston rod of each clamping cylinder 49 is fixed with a clamping plate 410 that is in contact with the surface of the receiving platform 47. The clamping plate 410 is L-shaped, with one protruding end being tapered. When the feeding conveyor transfers the product to the receiving platform, it pushes the previous product forward a certain distance. Then, the clamping cylinders drive the clamping plate to push out, thus creating a limit on the receiving platform and blocking the two products, serving a pre-waiting function.

[0027] like Figure 2The turntable assembly 2 includes a support plate 21 fixed on the operating table 1. The support plate 21 has a raised edge, with two large openings on its left and right sides that respectively connect to the receiving platform 47 and the unloading conveyor 7. A small opening on its front connects to the detection component 3. A turntable 22, with its surface in contact with the inner side of the support plate 21, is rotatably connected to it. The turntable 22 is cross-shaped with four semi-circular forks. A belt-driven drive device 23 is installed at the bottom of the operating table 1 to drive the turntable 22. The product first enters through the large opening on the left and is positioned in one of the forks of the turntable. The belt-driven drive device rotates the turntable, thus moving the product to the small opening. After detection by the detection component, the product moves to the large opening upon subsequent movement.

[0028] To further explain, a positioning cylinder 24 is installed on the surface of the operating table 1. The piston rod of the positioning cylinder 24 passes through the support plate 21. Simultaneously, four positioning holes 25 are provided on the turntable 22, each of which can be fitted with the piston rod of the positioning cylinder 24. When the turntable moves the product to a certain stage, the piston rod of the positioning cylinder extends upwards into the corresponding positioning hole, positioning the turntable and preventing displacement during loading, inspection, and unloading processes from affecting subsequent inspections.

[0029] like Figure 3 The detection assembly 3 includes a support frame 31 fixed on the operating table 1. The support frame 31 is F-shaped, with its cross-section extending above the turntable 22. At least six probe detection devices 32 are installed at one end of the support frame 31 above the turntable 22. A top-clamp cylinder 33 and two guide rods 34 are installed on the vertical surface of the support frame 31. The piston rod of the top-clamp cylinder 33 is fixed with a top-clamp block 35 connected to the guide rods 34. The top-clamp block 35 is opposite to a small opening on the support plate 21. When the product is below the probe detection device, the top-clamp cylinder drives the top-clamp block through the small opening to clamp and position the product in conjunction with the turntable's fork, preventing movement during detection and affecting the detection data. Then, the probe detection device moves the probe downwards to contact the upper surface of the product, thereby improving detection accuracy through multiple points of detection.

[0030] like Figure 5 The unloading assembly 5 includes a side frame 51 fixed on the operating table 1. The cross-section of the side frame 51 is located above the unloading conveyor table 7, and a front-push cylinder 52 is installed at one end of the cross-section. A downward-push cylinder 53 is installed on the piston rod of the front-push cylinder 52. A downward-push plate 54 is fixed to the piston rod of the downward-push cylinder 53. A retraction block 55 is fixed to the left side of the downward-push plate 54. The retraction block 55 is made of rubber. When the product is moved to dock with the unloading conveyor table, the downward-push cylinder drives the downward-push plate to move down until the retraction block is located in the inner circle of the product. Then, through the operation of the front-push cylinder, the downward-push plate moves the product from the large opening on the right side to the unloading conveyor table.

[0031] Further explanation: A side plate 56 is fixed on the operating table 1. An ejector cylinder 57 and two columns 58 are installed on the side plate 56. The piston rod of the ejector cylinder 57 is fixed with an ejector block 59 connected to the columns 58. When a product is transferred to the unloading conveyor, if the product is qualified, it is pushed out and moved for transfer. If the product is unqualified, the ejector cylinder drives the ejector block to push it out, thereby pushing the product to the side and removing it through the unloading channel, thus completing the product sorting.

[0032] The working principle of the above embodiments is as follows:

[0033] When two sets of products are conveyed to the receiving platform via the feeding conveyor, the clamping cylinder drives the clamping plate to push out, so that the protruding end of the clamping plate is positioned between the two sets of products to form a barrier, thereby achieving the pre-equalization function. In the initial state, the lowering cylinder drives the shifting block to move down, so that the shifting block moves into the inner circle of the product. Then, the pushing cylinder pushes it out, thereby moving the foremost product to the support plate and placing it in the concave surface of the turntable. The belt drive device operates, driving the turntable to rotate and moving the product to the area below the probe detection device. When the product is in each interval, the positioning cylinder pushes it up. The turntable is positioned by extending into the corresponding positioning hole. The top clamping cylinder drives the top clamping block to clamp and fix the product. Then, the flatness of the product is detected by multiple probe detection devices. After the detection is completed, the positioning cylinder retracts, and the turntable rotates again to move the detected product to dock with the unloading conveyor. The unloading block is initially located above the turntable. When the product moves below the unloading block, the cooperation of the downward pushing cylinder and the forward pushing cylinder pushes the product onto the unloading conveyor. When the product is unqualified, the ejection cylinder drives the ejection block to eject it, thereby ejecting the unqualified product and exporting it through the unloading channel.
