Description

Technical Field

[0001] The invention belongs to the technical field of parts detection, and in particular relates to a fast detection system for machining errors of large parts. Background Art

[0002] Machining error detection of parts refers to a series of processes to measure and evaluate the size, shape, position and other parameters of parts during the manufacturing process to determine whether they meet the design requirements and technical standards. Machining errors are usually caused by factors such as process, equipment, and materials, which may affect the function, performance and assembly accuracy of parts. Therefore, machining error detection is an important part of ensuring product quality.

[0003] In the prior art, for example, the technical solution described in the patent with publication number CN118258324A is: a roundness detection device for disc sleeve parts, which measures the roundness of disc sleeve parts through a V-shaped positioning block and a dial indicator. The V-shaped positioning block is fixed to the base by multiple V-shaped block fixing screws, one end face of the workpiece is placed on the inclined surface of the base, and the outer circle of the workpiece is positioned by the V-shaped positioning block. The probe of the dial indicator should be retracted inward by about 1 mm after contacting the workpiece, and tightened with two fixing seat screws, and the dial indicator is reset to zero. When the workpiece rotates in the V-shaped positioning block, the value of the dial indicator deviating from zero is the error value of the roundness.

[0004] In the prior art, the processing of large parts is usually done by multiple manufacturers together, and after the production is completed, they are assembled uniformly. For the detection of processing errors of large parts, most companies still use the traditional quality inspection method, and the specialists of the quality department are responsible for the inspection. This method relies heavily on manual inspection. Although it can identify some significant processing errors to a certain extent, it cannot guarantee that all potential processing errors will be checked one by one before leaving the factory every time. Once a problem is found, the assembly team may need to stop work for re-inspection and adjustment. In this way, the originally tight delivery time node will be seriously threatened, resulting in delays in equipment delivery, thereby affecting customer trust and satisfaction. Therefore, when the parts are assembled, they need to be inspected again to ensure that the parts meet the assembly requirements. However, at this time, the parts have been placed in place and cannot be moved at will, so the parts can only be inspected by assembly inspection tools. Summary of the invention

[0005] The purpose of the present invention is to provide a rapid detection system for large-part machining errors, so as to solve the problem that in the prior art proposed in the background technology, the machining errors of large parts are detected manually, but it is impossible to ensure that all potential machining errors are checked one by one before leaving the factory every time, and manual detection cannot detect large parts conveniently and quickly.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A large-scale parts machining error rapid detection system comprises a movable detection bracket, on which a surface detection component, a lateral detection component and a clamping component are arranged; wherein the surface detection component is arranged above the detection bracket, and the lateral detection component and the clamping component are arranged on the side wall of the detection bracket;

[0013] According to the above technical solution, four groups of lateral detection components are provided, and two groups of lateral detection components are respectively provided on the left and right sides of the detection bracket.

[0014] According to the above technical solution, the support column includes an inner column and an outer column, wherein a spring is sleeved on the inner outer wall, one end of the spring is connected to the inner column, and the other end of the spring is connected to the inner wall of the outer column.

[0015] According to the above technical solution, the inner column is a magnetic fixing rod that obtains magnetism when powered on. By powering on the inner column, the inner column obtains magnetism, thereby adsorbing and fixing the part to be tested.

[0032] like Figure 4 As shown, the clamping assembly includes a support structure 200, a mounting plate 300 and a support column 400; wherein one end of the support structure 200 is fixedly connected to the detection bracket 100; the other end of the support structure 200 is fixedly connected to the mounting plate 300; a mounting column is provided on one side of the mounting plate 300, and the support column 400 is provided inside the mounting column;

[0033] like Figure 4 As shown, the mounting post extends to the other side of the mounting plate 300, and an adjusting ring 500 is provided at the end of the mounting post; the adjusting ring 500 is rotatably connected to the mounting post; an internal thread is provided on the inner wall of the adjusting ring 500, and an external thread is provided on the supporting post 400, and the adjusting ring 500 is threadedly connected to the supporting post 400.

[0034] In the present invention, by simultaneously setting up a surface detection component and a lateral detection component, rapid and comprehensive detection of the surface and lateral dimensions of a part can be achieved, thereby improving detection efficiency and accuracy; the clamping component enables the system to adapt to parts of different sizes and shapes, ensuring the stability and non-deformation of the parts during the detection process, and reducing errors caused by improper clamping; through the threaded connection between the adjustment ring 500 and the support column 400, the user can conveniently and accurately adjust the clamping force and position, thereby adapting to different part shapes and requirements, and improving the flexibility of the system.

[0036] The detection system of the present invention significantly improves the detection efficiency, flexibility and accuracy of large-scale parts processing through the coordinated work of multiple components, and meets the needs of modern industry for fast, efficient and high-precision machine detection.

[0037] Embodiment 2

[0038] This embodiment is a further refinement of the first embodiment.

[0039] like Figure 1 As shown, the surface detection assembly includes a first camera 600 and a first laser sensor 700, wherein the first camera 600 and the first laser sensor 700 are slidably arranged on the crossbeam of the detection bracket 100. A driving device 800 is also arranged on the crossbeam of the detection bracket 100, and the driving device 800 is used to drive the surface detection assembly to move left and right.

[0040] Specifically, by setting the first camera 600 and the first laser sensor 700 on the crossbeam of the detection bracket 100, and driving the first camera 600 and the first laser sensor 700 to move on the crossbeam through the driving device 800, the position of the first camera 600 and the first laser sensor 700 can be adjusted left and right, so as to detect different positions on the upper surface of the part to be tested.

[0041] Furthermore, the driving device 800 adopts an existing device, such as a ball screw structure driven by a motor to drive the surface detection component to move.

[0042] The lateral detection assembly includes a second camera 900 and a second laser sensor 110, wherein the second camera 900 and the second laser sensor 110 are arranged on the side wall of the detection bracket 100. There are four groups of lateral detection assemblies, and two groups of lateral detection assemblies are arranged on the left and right sides of the detection bracket 100 respectively.

[0043] Further, the lateral detection assembly can move on the detection bracket 100. For example, by providing a pulley block driven by a motor and a traction rope, and by fixing the lateral detection assembly to the traction rope, the lateral detection assembly can be driven to move on the detection bracket 100.

[0044] Specifically, Figure 1As shown, four groups of transverse detection components are respectively arranged on both sides of the detection bracket 100, wherein the four groups of transverse detection components are arranged opposite to each other in pairs, and the transverse axis holes of the parts to be detected are detected by two groups of oppositely arranged transverse detection components.

[0045] This embodiment provides a specific detection method for lateral detection of parts.

[0046] Due to the large size of large parts, in order to save the processing time of large parts, it is usually necessary for multiple manufacturers to process together, and then assemble the parts after the processing is completed. Before assembling the parts, it is necessary to inspect the parts once. The purpose is to check whether the parts are coaxial, whether there are processing errors, and whether there is extrusion deformation during transportation after the parts are placed in place, so as to ensure the quality of the parts before assembly and avoid the situation where they cannot be assembled or there are deviations in the assembly. Therefore, an inspection before assembling the parts is necessary. Since it is inconvenient to move the parts after they are placed in place, the positions of the parts are usually not adjusted, and the parts are not moved to the inspection workshop for inspection. Therefore, the parts can only be inspected by assembling the inspection device on site.

[0047] The detection bracket in the present invention is composed of detachable brackets made of aluminum alloy. By splitting or combining these brackets, the detection bracket can be deployed at any position, which is convenient for the detection of large parts.

[0048] Further, such as Figure 1 As shown, after the two guide rails 118 are laid, a connecting frame is provided on the two guide rails 118 , and the connecting frame is used to fix the two guide rails 118 .

[0049] Step 1: Figure 5 As shown, firstly, a target paper (with a reflector) is pasted on a transverse axial hole (assuming it is hole A) of the part to be tested.

[0050] Step 2: Start the lateral detection component and reset the encoder to zero before starting; set the base point (move the second laser sensor 110 until it first touches the edge of hole A, such as Figure 6 The second laser sensor 110 receives the reflected signal from the target paper at this time.

[0051] Step 3: The lateral detection assembly slowly moves upward along the detection bracket 100, and the second laser sensor 110 continues to measure the distance. The signal of the second laser sensor 110 remains unchanged until the "2" position (such as Figure 6 As shown), the signal of the second laser sensor 110 changes, the distance measurement stops, and a distance d1 from point "1" to point "2" is recorded. The distance d1 recorded by the encoder is transmitted to the computer through wireless transmission to calculate the midpoint distance and coordinates O (as shown in FIG. Figure 7 and controls the midpoint coordinates calculated by the lateral detection component.

[0052] Step 4: The detection bracket 100 moves rightward along the guide rail 118 again, and the second laser sensor 110 continues to measure the distance. The signal of the second laser sensor 110 remains unchanged until the "3" position (such as Figure 8 As shown), the signal changes, the distance measurement stops and the encoder is reset to zero, the base point is set, and then the encoder moves leftward along the guide rail 118 until the "4" position (as shown) is reached. Figure 8 As shown), stop measuring distance, record a distance d3, send d2 and d3 to the computer by wireless transmission, and calculate the midpoint distance and coordinate O1 (this is the center of the hole) by the distances d2 and d3.

[0053] Step 5: Repeat steps 1 to 4 to measure the center coordinate O2 of another transverse shaft hole (assumed to be hole B).

[0054] Step 6: Compare the coordinates of O1 and O2 to see if they are consistent. If so, they are coaxial. If not, they are not coaxial and the parts need to be adjusted.

[0055] like Figure 3 As shown, the support column 400 includes an inner column 111 and an outer column 112, wherein a spring 113 is sleeved on the inner outer wall, one end of the spring 113 is connected to the inner column 111, and the other end of the spring 113 is connected to the inner wall of the outer column 112. The inner column 111 is a magnetic fixing rod, and by energizing the inner column 111, the inner column 111 acquires magnetism, thereby adsorbing and fixing the part to be tested.

[0056] Specifically, when it is necessary to clamp the part to be tested, the support columns 400 on both sides of the detection bracket 100 are driven by the support structure 200 to move relative to each other to clamp the part to be tested; when the end of the inner column 111 contacts the surface of the part to be tested, the inner column 111 will be squeezed, and the compression spring 113 will be used to buffer the inner column 111 and the part to be tested, so as to prevent the inner column 111 from directly colliding with the part to be tested, thereby causing damage to the surface of the part to be tested.

[0057] like Figure 2 As shown, when clamping an irregular part surface, the adjusting ring 500 can be rotated to drive the end of the outer column 112 to rotate and move through the internal thread of the adjusting ring 500, thereby adjusting the length of the support column 400, so that the support column 400 can clamp the irregular part surface, thereby improving the use range of the clamping assembly.

[0058] The support structure 200 includes a mounting frame 114, a first support frame 115 and a second support frame 116; wherein the first support frame 115 is slidably disposed on the mounting frame 114, the second support frame 116 is rotatably disposed on the mounting frame 114, and the first support frame 115 and the second support frame 116 are hinged.

[0059] The support structure 200 further includes a driving cylinder 117 , one end of which is fixedly disposed on the mounting frame 114 , and the other end of which is fixedly connected to the first support frame 115 .

[0060] Specifically, the first support frame 115 is pushed and moved by driving the cylinder 117 , so that the first support frame 115 drives the second support frame 116 to rotate together, thereby propping up the mounting plate 300 .

[0061] A guide rail 118 is further provided below the detection bracket 100 , and the detection bracket 100 is slidably disposed on the guide rail 118 .

[0062] Specifically, the guide rail 118 is used to detect the movement of the bracket 100. A driving wheel is arranged below the detection bracket 100, and the driving wheel is driven by a motor to drive the movement of the detection bracket 100.

[0063] The working principle of the present invention is as follows: when in use, the detection bracket 100 is moved to adjust the position of the detection bracket 100 so that the part to be tested is in the middle of the detection bracket 100. Then, the first support frame 115 is pushed and driven by the driving cylinder 117 to move, so that the first support frame 115 drives the second support frame 116 to rotate together, thereby propping up the mounting plate 300, and the support columns 400 on both sides of the detection bracket 100 are driven to move relatively through the mounting plate 300 to clamp the part to be tested; the end of the outer column 112 is driven to rotate and move through the internal thread of the adjusting ring 500, thereby adjusting the length of the support column 400, so that the support column 400 can clamp the irregular surface of the part.

[0064] The surface and the transverse axis hole of the part to be tested are then tested by means of the provided surface testing component and transverse testing component.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
