Description

Technical Field

[0001] This invention relates to the field of crankshaft marking technology, and more specifically, to a crankshaft marking device. Background Technology

[0002] Crankshaft marking refers to the process of engraving different categories of marks onto the manufactured crankshafts to facilitate differentiation and classification, and to help identify defective crankshafts.

[0003] However, when screening out unqualified crankshafts, existing crankshafts need to be collected together, measured sequentially, and then marked with unqualified labels using separate equipment. This process is too cumbersome and requires classifying and placing unqualified crankshafts, making the measurement, marking, and classification of unqualified crankshafts quite troublesome and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a crankshaft marking device to solve the problem that after the crankshaft is produced, each one needs to be measured and then the defective ones need to be marked. These two steps are performed by separate equipment, which leads to a lot of crankshaft transfers and makes the measurement and marking process very cumbersome.

[0005] The embodiments of the present invention are achieved through the following technical solutions:

[0006] This invention provides a crankshaft marking device, comprising a main body, pins arranged on both sides of the middle of the main body, a test frame arranged at the top of the middle of the main body, several pneumatic measuring devices arranged at the bottom of the test frame, and a laser printer arranged on one side of the middle of the main body. The device is characterized by having a placement frame arranged in the middle of the main body, a lifting column arranged at the bottom of the placement frame, the bottom of the lifting column connected to a slide rail via a plate, several assembly blocks arranged in the middle of the placement frame, a connecting frame arranged around the assembly blocks, and sliding components arranged on both sides of the middle of the placement frame, allowing the assembly blocks to move along the sliding components.

The rotating shaft is located on both sides of the connecting frame, the deflecting shaft is located on one side of the rotating shaft, the stop block is located on one side of the deflecting shaft, and the deflecting groove is located on both sides of the connecting frame.

[0008] Both sides of the rotation axis and the deflection axis protrude onto the surface of the connecting frame, and the portion of the rotation axis and the deflection axis protruding outwards from the connecting frame is larger.

[0009] The surface of the rotating shaft is provided with tooth marks that mesh with the two sides of the assembly block;

[0010] A rubber layer is provided on the top surface of the block;

[0011] Each combination block has a rotation axis and a deflection axis, and the combination of each rotation axis and deflection axis is set up alternately in the vertical direction;

[0012] The sliding component includes a slider, a limiting block, and a fitting groove. The slider is located on both sides of the middle part of the connecting frame, the limiting block is located on both sides of the slider near the top, and the fitting groove is located on both sides of the slider.

[0013] The assembly block includes a slide, a limiting groove, and a fitting block. The slide is located on both sides of the assembly block, the limiting groove is located on both sides of the slide near the top, and the fitting block is located on both sides of the slide opening near the top.

[0014] The slide groove cooperates with the slider, the limiting groove cooperates with the limiting block, the fitting groove cooperates with the fitting block, and the top of the fitting block is connected to the fitting groove by a spring.

Detailed Implementation

[0028] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The following is combined Figures 1 to 7 The present invention will be described in detail below.

[0030] A crankshaft marking device includes a body 1, with ejector pins 101 arranged on both sides of the middle of the body 1, a test frame 2 arranged on the top of the middle of the body 1, several pneumatic measuring devices 201 arranged at the bottom of the test frame 2, a laser printer 4 arranged on one side of the middle of the body 1, a placement frame 3 arranged in the middle of the body 1, a lifting column 301 arranged at the bottom of the placement frame 3, the bottom of the lifting column 301 being connected to a slide rail 302 via a plate, several assembly blocks 304 arranged in the middle of the placement frame 3, a connecting frame 303 arranged around the assembly blocks 304, and sliding components arranged on both sides of the middle of the placement frame 3, the assembly blocks 304 moving along the sliding components.

[0031] First, the crankshaft to be measured and coded is placed on the placement rack 3. Then, the crankshaft is stabilized and fixed by the abutment of the two end pins 101. Next, the pneumatic measuring device 201 on the test rack 2 clamps the crankshaft's neck. Gas is then ejected from the air jets on both sides of the grippers of the pneumatic measuring device 201 onto the crankshaft's neck. The diameter of the crankshaft's neck is calculated based on the resistance of the ejection, thus determining whether the crankshaft meets the standard. Then, the placement rack 3 is moved along the bottom slide rail 302 to move the crankshaft to one side of the laser printer 4. The crankshaft is then aligned with the laser printer 4 by the raising and lowering of the lifting column 301 for coding processing. This facilitates the classification of the crankshaft, allowing for direct coding processing after measurement, and timely detection of unqualified necks.

[0032] Furthermore, the sliding assembly includes a slider 3031, a limiting block 30311, and a fitting groove 30312. The slider 3031 is disposed on both sides of the middle portion of the connecting frame 303, the limiting block 30311 is disposed on both sides of the slider 3031 near the top, and the fitting groove 30312 is disposed on both sides of the slider 3031. The assembly block 304 includes a sliding groove 3041, a limiting groove 3042, and a fitting block 3043. The sliding groove 3041 is disposed on both sides of the assembly block 304, and the limiting groove 3042 is disposed on the sliding groove 3041. On both sides near the top of 041, the fitting blocks 3043 are set at the opening of the slide groove 3041 near the top. The slide groove 3041 cooperates with the slider 3031, the limiting groove 3042 cooperates with the limiting block 30311, the fitting groove 30312 cooperates with the fitting block 3043, and the top of the fitting block 3043 is connected to the fitting groove 30312 by a spring. One side of the limiting block 30311 is connected to the grooves on both sides of the slider 3031 by a spring, and the top of the limiting block 30311 is set as an inclined slope.

[0033] The placement frame 3 itself is composed of multiple assembly blocks 304 that fit together. Each assembly block 304 is connected to the slider 3031 on the connecting frame 303 via the sliding grooves 3041 on both sides. When the crankshaft is placed on the assembly block 304, the first part that comes into contact will move the assembly block 304 down along the slider 3031 due to its weight. This allows the placement frame 3, which is assembled from the assembly blocks 304, to adapt to the crankshaft until both sides of the crankshaft abut against the inner wall of the connecting frame 303, thus placing the crankshaft stably and preventing it from easily shifting.

[0034] Simultaneously, after the assembly block 304 moves a certain distance through the slide groove 3041, the limiting block 30311 will pop out and engage with the limiting groove 3042 to limit it, preventing the assembly block 304 from moving further down and separating it from the connecting frame 303. This also limits the downward movement of the assembly block 304, preventing it from moving further down. The inclined surface at the bottom of the limiting block 30311 allows the assembly block 304 to retract when it resets, enabling the assembly block 304 to reset. The engaging blocks 3043 on both sides of the slide groove 3041 will also engage with the engaging groove 30312 when they move down, compressing the spring on one side so that the assembly block 304 can reset itself when the crankshaft is removed.

[0035] Furthermore, the connecting frame 303 also includes a rotating shaft 3032, a deflecting shaft 3033, a stop block 3034, and a deflection groove 3035. The rotating shaft 3032 is disposed on both sides of the connecting frame 303, the deflecting shaft 3033 is disposed on one side of the rotating shaft 3032, the stop block 3034 is disposed on one side of the deflecting shaft 3033, and the deflection groove 3035 is disposed on both sides of the connecting frame 303. Both sides of the rotating shaft 3032 and the deflecting shaft 3033 protrude from the surface of the connecting frame 303, and the portion of the rotating shaft 3032 and the deflecting shaft 3033 protruding from the outward side of the connecting frame 303 is larger. The surface of the rotating shaft 3032 is provided with tooth marks that mesh with the two sides of the combined block 304. The top surface of the stop block 3034 is provided with a rubber layer. The rotating shaft 3032 and the deflecting shaft 3033 correspond to each combined block 304, and each combination of the rotating shaft 3032 and the deflecting shaft 3033 is arranged in an alternating vertical arrangement.

[0036] Finally, as the assembly block 304 moves downward, the toothed grooves on both sides engage and fit against the surface of the rotating shaft 3032. The downward movement of the assembly block 304 causes the rotating shaft 3032 to begin rotating. When the rotating shaft 3032 rotates, it causes the deflection shaft 3033 to rotate as well. When the deflection shaft 3033 rotates, it causes one of the abutments 3034 to deflect, changing its angle and causing it to move vertically towards the center, thus abutting against the surface of the crankshaft and thus limiting the crankshaft. The lowest point of the crankshaft will cause the abutment 3034 to deflect to the maximum and abut against the crankshaft, thus adapting to the different specifications of the crankshaft's bending. Because the width of the abutment 3034 is less than the length of the crankshaft's neck, it will not affect the measurement of the pneumatic measuring device 201 when clamped. By clamping and stably placing the crankshaft, it will not shift on the placement frame 3 due to the loss of the abutment of the ejector pin 101 during the process of moving it to the laser printer 4 via the slide rail 302, thus preventing the crankshaft from shifting on the placement frame 3 and causing a decrease in the accuracy of the laser printer 4.

[0037] Since the deflection shaft 3033 connecting the abutment block 3034 is located on one side of the rotation shaft 3032, it will abut against the side of the lowest bending point when the abutment block 3034 deflects, thus avoiding the abutment block 3034 not being able to abut against the lowest bending point due to the bending point being too low.

[0038] The following is a detailed implementation process of this invention: First, the crankshaft to be coded and measured is placed on the placement rack 3. Then, the crankshaft is stabilized and fixed by the abutment of the two end pins 101. Next, the pneumatic measuring device 201 on the test rack 2 clamps the crankshaft onto the crank neck. Gas is then ejected from the jet holes on both sides of the grippers of the pneumatic measuring device 201 onto the crank neck. The crank neck diameter is calculated based on the resistance of the ejection, thereby determining whether the crankshaft meets the standard. Finally, the crankshaft is placed on the placement rack 3. The crankshaft is moved along the bottom slide rail 302 to one side of the laser printer 4. Then, the crankshaft is aligned with the laser printer 4 by raising and lowering the lifting column 301 for coding, facilitating crankshaft classification. The placement rack 3 itself is composed of multiple assembled blocks 304 that fit together. Each assembled block 304 is connected to the slider 3031 on the connecting frame 303 via the sliding grooves 3041 on both sides. When the crankshaft is placed on the assembled block 304, the first contact is with the... Due to its weight, some of the contacting assembly blocks 304 move downwards along the slider 3031, allowing the placement frame 3 to adapt to the crankshaft until both sides of the crankshaft abut against the inner wall of the connecting frame 303, thus stabilizing the crankshaft and preventing it from easily shifting. Simultaneously, after the assembly blocks 304 move a certain distance via the slide groove 3041, the limiting block 30311 pops out and engages with the limiting groove 3042, preventing the assembly blocks 304 from moving further downwards and thus separating them from the connecting frame. 303, at the same time, the downward movement of the assembly block 304 is limited, so that it will not continue to move downward. The inclined slope at the bottom of the limiting block 30311 allows the assembly block 304 to be pushed to retract when it is reset, so that the assembly block 304 can be reset. The fitting blocks 3043 on both sides of the slide 3041 will also fit into the fitting groove 30312 when they move downward, so as to compress the spring on one side, so that the assembly block 304 can be reset by itself when the crankshaft is removed.

Various modifications and variations can be made to the present invention by those skilled in the art.
