Description

Technical Field

[0001] This invention relates to the field of engine measurement technology, and more specifically to an automatic measurement system for cylinder block wheel train holes. Background Technology

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc.; for example, internal combustion engines usually convert chemical energy into mechanical energy; after the cylinder bores, crankshaft bores and camshaft bores of the engine block are precision machined, it is often necessary to measure the bore diameter;

[0003] For example, Chinese patent CN207050697U, entitled "Engine Cylinder Block Measuring Device," includes a roller conveyor and a measuring mechanism mounted on the roller conveyor. The measuring mechanism includes a frame mounted on the roller conveyor. The measuring mechanism also includes a first measuring component connected to the frame for detecting the diameter of the cylinder bore of the cylinder block. The first measuring component includes a detection end, and the frame is provided with a lifting mechanism for driving the detection end to extend into or away from the cylinder bore of the cylinder block. The engine cylinder block measuring device of this application can measure the size of the cylinder bore of cylinder blocks of different sizes, and the first measuring component can automatically perform the measurement under the drive of the lifting mechanism, thus improving the measurement efficiency.

However, whether it is manual measurement using a dial indicator or automatic measurement using a measuring device as described in the aforementioned patent, it is quite troublesome to test multiple holes in different directions on the cylinder block during the measurement process. Manual measurement can only be performed one by one, and the aforementioned patent can only measure the holes on the top of the engine cylinder block.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-8 An automatic measurement system for cylinder block wheel train bores includes a base 7 and a feed roller conveyor 1 and a discharge roller conveyor 9 fixedly mounted on the base 7. It also includes: a first measuring component 5, comprising a cylinder bore pneumatic probe 56 mounted on the base 7 for measuring the cylinder bore dimensions at the top of the engine block; a second measuring component 6, comprising a crankshaft bore pneumatic probe 61 and a camshaft bore pneumatic probe 62 mounted on one side of the base 7 for measuring the crankshaft bores and camshaft bores on the sidewalls of the engine block; and a rotation positioning component 4 for rotating the engine block, thereby enabling the engine block to simultaneously accommodate the detection of the cylinder bore pneumatic probe 56, the crankshaft bore pneumatic probe 61, and the camshaft bore pneumatic probe 62.

[0031] In another embodiment provided by the present invention, the rotary positioning assembly 4 includes a rotary motor 47 fixedly mounted on a base 7, a plate 41 fixedly connected to the base 7, a rotary frame 48 fixedly connected to the output end of the rotary motor 47 passing through the plate 41, a lifting cylinder vertically slidingly mounted on the rotary frame 48, a power roller conveyor 45 fixedly connected to the output end of the lifting cylinder, and a positioning post 42, a cylindrical pin 43, and a chamfered pin 44 slidingly passing through the power roller conveyor 45 fixedly mounted on the rotary frame 48; when the engine cylinder moves onto the power roller conveyor 45, until the engine cylinder... The engine block is moved to the designated position. At this time, the power roller conveyor 45 can be raised and lowered by the lifting cylinder. The engine block will follow the power roller conveyor 45 to rise and fall. At the same time, the bottom of the engine block is provided with positioning holes that are compatible with the positioning pin 42, cylindrical pin 43 and chamfered pin 44. Therefore, during the process of the engine block descending, the positioning pin 42, cylindrical pin 43 and chamfered pin 44 slowly extend from the surface of the power roller conveyor 45 and are inserted into the corresponding positioning holes one by one, thereby positioning the engine block and avoiding misalignment of the engine block that would affect subsequent measurements.

[0032] In another embodiment provided by the present invention, a stop 46 is fixedly installed on one side of the power roller conveyor 45, and the top of the stop 46 extends into the middle of the power track; an annular cover 3 is fixedly connected to the flat plate 41, and an identification barcode scanner is fixedly connected to the inner wall of the annular cover 3. When the engine cylinder body descends with the power roller conveyor 45, the identification code at the bottom of the engine cylinder body will enter the annular cover 3 and be identified by the identification barcode scanner inside the annular cover 3, thereby identifying the model of the engine cylinder body. At the same time, when the engine cylinder body enters the power roller conveyor 45 from the feed roller conveyor 1, as the engine cylinder body moves until one end abuts against the stop 46, since the stop 46 is provided with a pressure sensor, at this time, as the engine cylinder body abuts against the stop 46, the pressure sensor on the stop 46 will send a feedback signal to the display controller 2 installed on one side of the base 7. The power roller conveyor 45 includes a roller frame and rollers rotatably installed on the roller frame. A sprocket is fixedly installed on several rollers, and the several sprockets are connected by a chain. The connection is as follows: one roller is driven by a power motor to rotate. When the display controller 2 receives a signal from the pressure sensor, it sends a stop signal to the power motor, which then stops running, causing the engine block to stop on the power roller 45. Next, the rotary motor 47 drives the rotating frame 48 to rotate, causing the engine block to rotate 90 degrees. At this time, the crankshaft hole and camshaft hole on the side wall of the engine block will align with the second measuring component 6, and the cylinder hole at the top of the engine block will also align with the first measuring component 5. After the measurement is completed, the rotary motor 47 drives the rotating frame 48 to rotate 90 degrees, causing the engine block to approach the discharge roller 9. At the same time, the power motor is started, causing it to rotate in the opposite direction, so that the engine block on the power roller 45 enters the discharge roller 9. Then, the rotating frame 48 is rotated, so that the stop block 46 on the power roller 45 changes position, preventing the stop block 46 from affecting the entry of the engine block on the feed roller 1 into the power roller 45.

[0033] In another embodiment provided by the present invention, the first measuring component 5 further includes a support frame 51 fixedly mounted on the base 7. A slide frame 52 is slidably connected to the support frame 51 via a first driving mechanism. The cylinder bore pneumatic probe 56 is mounted on the slide frame 52 via a second driving mechanism. The first driving mechanism includes a first driving cylinder 55 fixedly mounted on the support frame 51. The output end of the first driving cylinder 55 is fixedly connected to the slide frame 52. The slide frame 52 can be driven to slide on the support frame 51 by the first driving cylinder 55. The second driving mechanism includes a second driving cylinder 53 fixedly mounted on the slide frame 52. The second driving cylinder 53 and the cylinder bore pneumatic probe 56 are fixedly connected by a connecting frame 54. The cylinder bore pneumatic probe 56 can be driven to insert into the cylinder bore at the top of the engine block for measurement by the second driving cylinder 53.

[0034] In another embodiment provided by the present invention, the second measuring component 6 further includes a base frame 63 fixedly mounted on a base 7. A plurality of movable frames 66 are slidably mounted on the base frame 63. The crankshaft bore pneumatic probe 61 and the camshaft bore pneumatic side probe are mounted one-to-one on each movable frame 66. Each movable frame 66 and the base 7 are fixedly connected to a telescopic cylinder 67. The telescopic cylinder 67 can push each movable frame 66 to move. At this time, the movable frame 66 will drive the crankshaft bore pneumatic probe 61 or the camshaft bore pneumatic side probe to move, so that the crankshaft bore pneumatic probe 61 and the camshaft bore pneumatic side probe can be inserted into the engine cylinder for detection. A connecting cylinder 68 is fixedly connected to the base 7. The output end of the connecting cylinder 68 is fixedly connected to the base frame 63, and a bellows 69 is provided between the connecting cylinder 68 and the base frame 63. The position of the base frame 63 can be adjusted by the connecting cylinder 68, so that two different sets of crankshaft bore pneumatic probes 61 and camshaft bore pneumatic probes 62 can be used.

[0035] In another embodiment provided by the present invention, a first floating assembly 58 is installed between each connecting frame 54 and each cylinder bore pneumatic probe 56 in a one-to-one correspondence, and a second floating assembly 65 is provided between each movable frame 66 and each crankshaft bore pneumatic probe 61 and camshaft pneumatic probe in a one-to-one correspondence; wherein the first floating assembly 58 and the second floating assembly 65 each include a frame 10 and a plurality of floating springs 12 fixedly installed in the frame 10, and a floating block 11 is fixedly installed at one end of the plurality of floating springs 12 away from the frame 10. Each crankshaft bore pneumatic probe 61, camshaft pneumatic probe and cylinder bore pneumatic probe 56 is respectively installed on the corresponding floating block 11. When each crankshaft bore pneumatic probe 61, camshaft pneumatic probe and cylinder bore pneumatic probe 56 is inserted into the engine cylinder, Because there are slight errors in the machining of various holes in the engine block, the first floating component 58 and the second floating component 65 ensure that the pneumatic probes 61, camshaft pneumatic probes and cylinder bore pneumatic probes 56 will not be hard-hit and damaged due to errors when they are inserted into the engine block. The first pneumatic-electric converter 57 is fixedly connected to each connecting bracket 54, and the second pneumatic-electric converter is fixedly connected to each moving bracket 66. The first pneumatic-electric converter 57 and the second pneumatic-electric converter convert the air flow signals of the cylinder bore pneumatic probes 56, crankshaft pneumatic probes 61 and camshaft pneumatic probes 62 into electrical signals for transmission and display, i.e., output measurement data.

[0036] In another embodiment provided by the present invention, a first calibration component 59 is fixedly connected to the support frame 51, and a second calibration component 64 is fixedly connected to the base 7. The first calibration component 59 has two first calibration holes. Before each day's work or after a period of testing, two cylinder bore pneumatic probes 56 are inserted into the two first calibration holes to calibrate the two cylinder bore pneumatic probes 56 and check whether there is a large offset between the two cylinder bore probes. At the same time, the two second calibration components 64 correspond to two sets of side hole measuring components, each set of side hole measuring components including a crankshaft hole pneumatic probe 61 and a camshaft hole pneumatic probe 62. The two second calibration components 64 each have two second calibration holes. The two second calibration components 64 correspond to two different models of engine cylinder blocks. The two sets of side hole measuring components are calibrated by the two second calibration components 64 respectively.

[0037] In another embodiment provided by the present invention, a marking structure 8 is provided on the discharge roller conveyor 9. The marking structure 8 includes a fixed frame 81 that is sleeved on one side of the discharge roller conveyor 9. A marking machine 82 is horizontally slidably mounted on the fixed frame 81 along its long axis. A side frame 84 is fixedly connected to one side of the marking machine 82. A telescopic plate 85 is horizontally slidably mounted on the side frame 84. The fixed frame 81 has screw holes. After the fixed frame 81 is sleeved on one side of the discharge roller conveyor 9, the fixed frame 81 is installed on the discharge roller conveyor 9 using screws. At the same time, the side frame 84 is installed on the marking machine 82 away from the first side. When the engine cylinder enters the discharge roller conveyor 9 and slides out of the discharge roller conveyor 9, until one side of the engine cylinder abuts against the telescopic plate 85 of the side frame 84, the telescopic plate 85 will be driven by the engine cylinder and move simultaneously. At the same time as the telescopic plate 85 moves, it will drive the side frame 84 and the marking machine 82 to move. The marking machine 82 will move synchronously with the engine cylinder to facilitate marking. This allows the marking machine 82 to mark the engine cylinder without stopping the engine cylinder, thereby improving the discharge efficiency.

[0038] In another embodiment provided by the present invention, a top rod 86 is fixedly connected to the top of the fixed frame 81, and a stop block 851 is fixedly connected to the bottom of the telescopic plate 85. The top rod 86 is provided with a bevel. When the telescopic plate 85 slides along the engine cylinder block, the stop block 851 at the bottom of the telescopic plate 85 will always abut against the bevel of the top rod 86 until the generator cylinder block moves to the designated position. At this time, the marking machine 82 will finish marking the engine cylinder block. At the same time, since the stop block 851 slides along the bevel of the top rod 86, the telescopic plate 85 will be driven by the stop block 851 to move away from the engine cylinder block. After reaching the designated position, the telescopic plate 85 will disengage from the engine cylinder block, thereby causing the marking machine 82 to stop moving. The stop block 851 is cylindrical.

[0039] In another embodiment provided by the present invention, a pull plate 811 is fixedly connected to the fixed frame 81, a first spring 83 is fixedly connected between the pull plate 811 and the marking machine 82, a limit plate 812 is also fixedly connected to the fixed frame 81, a protruding plate 841 is fixedly connected to the side frame 84, and a second spring is fixedly connected between the protruding plate 841 and the telescopic plate 85; when the marking machine 82 moves with the engine cylinder, the first spring 83 will be stretched. When the marking machine 82 is separated from the engine cylinder, the first spring 83 will restore its elasticity, thereby pulling the marking machine 82 to move, and cooperating with the limit plate 812 to reset the marking machine 82. At the same time, the second spring will also push the telescopic plate 85 to extend from the surface of the side frame 84, so that the telescopic plate 85 abuts against the next engine cylinder.

[0040] In another embodiment provided by the present invention, a reset plate 87 is fixedly connected to the top of the fixed frame 81, and a misalignment plate 88 is rotatably mounted on the reset plate 87. A third spring 871 is fixedly connected between the misalignment plate 88 and the reset plate 87. When the abutment block 851 moves along the inclined side of the push rod 86 until the abutment block 851 abuts against the misalignment plate 88, the misalignment plate 88 will rotate and open as the abutment block 851 continues to move. After the abutment block 851 is completely removed from the surface of the misalignment plate 88, the third spring 871 will pull the misalignment plate 88 to reset, so that the end of the misalignment plate 88 away from the reset plate 87 abuts against the inclined side of the push rod 86. When the telescopic plate 85 is removed from the cylinder surface, the abutment block 851 will move from the side of the misalignment plate 88 away from the push rod 86 to the side of the reset plate 87 away from the push rod 86, so that the telescopic plate 85 will not extend too far from the surface of the side frame 84, thereby reducing the contact between the telescopic plate 85 and the cylinder surface when it is reset.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
