Description

Technical Field

[0001] The invention relates to the technical field of connecting rod processing, in particular to a subassembly device for connecting rods. Background Art

[0002] The connecting rod is used to connect the piston and the crankshaft, and transmit the force acting on the piston to the crankshaft, thereby converting the reciprocating motion of the piston into the rotational motion of the crankshaft.

[0003] In order to avoid assembly errors, the corresponding cylinder number is usually engraved on the connecting rod before assembly, and then the bolts between the connecting rod cover and the connecting rod body are loosened, and finally the connecting rod cover and the connecting rod body are separated to facilitate subsequent installation. The existing engraving, bolt tightening and separation of the connecting rod cover and the connecting rod body are three independent steps, and three processes are required to complete the three steps. When the connecting rod cover and the connecting rod body are separated, the inner side of the connecting rod cover is manually hit with a hammer. This will increase the labor intensity of the staff on the one hand, and take a long time on the other hand, affecting the processing efficiency. On the other hand, hitting the connecting rod cover with a hammer will cause the connecting rod cover to be sticky with oil residue on the hammer, affecting the installation accuracy.

[0031] See also Figures 1 to 7 As shown, the present invention provides a subassembly device for connecting rods, comprising an imprinting mechanism 20, a bolt tightening mechanism 30, an expansion mechanism 40 and a pressing mechanism 50 installed on a first frame 10. The imprinting mechanism 20 is installed above the expansion mechanism 40. When the connecting rod 60 is placed on the expansion mechanism 40, the pressing mechanism 50 presses the connecting rod 60, and the connecting rod 60 is directly imprinted through the imprinting mechanism 20. Then, the bolts between the connecting rod body 601 and the connecting rod cover 602 are loosened through the bolt tightening mechanism 30, and finally the connecting rod body 601 and the connecting rod cover 602 are separated by expansion.

[0032] The engraving mechanism 20 is used to engrave the corresponding model on the connecting rod 60. Debris will be generated during the engraving process, so a dust suction mechanism 101 is installed on the first frame 10. The dust suction mechanism 101 is arranged corresponding to the engraving mechanism 20. When debris is generated, the dust suction mechanism 101 sucks the debris away through negative pressure suction.

[0033] like Figures 3 to 5As shown, the expansion mechanism 40 includes a second frame 405 and a first positioning rod 401 and a second positioning rod 402 mounted on the second frame 405. The small diameter end of the connecting rod 60 is sleeved on the first positioning rod 401, and the large diameter end of the connecting rod 60 is sleeved on the second positioning rod 402. A plurality of holes at different positions can be provided on the second frame 405, so that it can be suitable for a variety of different connecting rods 60.

[0034] The second positioning rod 402 includes a fixed portion 403 and an expanding portion 404. A first sliding mechanism is provided on the second frame 405. A first power 411 connected to the first sliding mechanism is installed on the second frame 405. The expanding portion 404 is connected to the first sliding mechanism, and the first power 411 can drive the first sliding mechanism to slide. When the connecting body 60 is installed on the second positioning rod 402, the expanding portion 404 and the fixed portion 403 are closed. When the first sliding mechanism slides to the right, the expanding portion 404 is separated from the fixed portion 403, so that the connecting rod body 601 and the connecting rod cover 602 are separated.

[0035] The first sliding mechanism can slide relative to the first frame 10, and the first sliding mechanism includes a first connecting plate 406 and a first vertical plate 407 and a second vertical plate 408 located on both sides of the first connecting plate 406, the expansion part 404 is connected to the first vertical plate 407, and the first connecting plate 406 is connected to the movable end of the first power 411.

[0036] The first sliding mechanism also includes a first base plate 420 and a first slide rail 409 installed under the first base plate 420 . The first connecting plate 406 , the first vertical plate 407 and the second vertical plate 408 are all installed on the first base plate 420 . A first sliding block that cooperates with the first slide rail 409 is provided at the bottom of the first base plate 420 .

[0037] The first frame 10 includes a fixed plate 413 and two side plates 414. The fixed plate 413 is mounted on the first frame 10. The two side plates 414 are connected to the fixed plate 413. The two side plates 414 are L-shaped on one side of the first moving mechanism. The second connecting plate 412 is mounted at the L-shaped notch of the side plate 414. The second connecting plate 412 connects the two side plates 414. The first slide rail 409 is mounted on the second connecting plate 412. The bottom of the first bottom plate 420 is equipped with a first slider that matches the first slide rail 409.

[0038] The first power 411 may be a cylinder, a motor or a hydraulic cylinder. In some embodiments, the first power 411 is a cylinder, and the movable end of the cylinder is connected to the first connecting plate 406 .

[0039] The expansion part 404 is installed on the first vertical plate 407. The expansion part 404 and the fixing part 403 are both semi-cylinders, which are closed to form a cylinder. The expansion part 404 and the fixing part 403 both include a limiting section 421 and a fixing section 422. The diameter of the limiting section 421 is greater than the diameter of the fixing section 422.

[0040] The limiting section 421 is in contact with the first vertical plate 407. The second frame 405 is provided with a first positioning column at the fixed portion 403 corresponding to the fixed portion 403, and the fixed portion 403 is provided with a first positioning hole. The second frame 405 is provided with a second positioning column 410 at the expanded portion 404 corresponding to the expanded portion 404, and the expanded portion 404 is provided with a second positioning hole.

[0041] The first positioning hole has connection holes 415 connected to the first vertical plate 407 above and below, and the second positioning hole has connection holes 415 connected to the first vertical plate 407 above and below. The connection holes 415 extend from one side of the clamping mechanism 50 to the side plate 414, and the bolts are connected from the front.

[0042] In some embodiments, in order to allow the large diameter end of the connecting rod 60 to be smoothly mounted on the second positioning rod 402, the expanding portion 404 and the fixing portion 403 are not a complete semi-cylinder, and a groove 423 is provided on the upper and lower sides of the expanding portion 404 and the fixing portion 403, so that a complete circle is not formed when the expanding portion 404 and the fixing portion 403 are closed.

[0043] The end of the fixed part 403 away from the first frame 10 is connected with a pressing block 416, which is arranged toward the expanding part 404. The expanding part 404 is provided with a corresponding avoidance groove at the corresponding pressing block 416. When the expanding part 404 and the fixed part 403 are closed, the outer surface of the pressing block 416 is flush with the end surfaces of the expanding part 404 and the fixed part 403. After the multiple connecting rods 60 are installed on the second positioning rod 402, the outer side surface of the outermost connecting rod 60 is basically flush with the end surfaces of the expanding part 404 and the fixed part 403. The clamping mechanism 50 also contacts the pressing block 416 when clamping the connecting rod 60. The pressing block 416 can prevent the clamping block 503 from separating the expanding part 404 and the fixed part 403 during the clamping process.

[0044] The expansion part 404 and the fixing part 403 can be removed from the side plate 414. For the convenience of subsequent installation, a positioning seat 417 is set on the first frame 10, and a positioning plane 418 is set on the outer edge of the fixing part 403. When installing the fixing part 403, first insert the first positioning hole and the first positioning column, then contact the positioning seat 417 with the positioning plane 418, and screw the positioning pin 419 on the positioning seat 417 into contact with the positioning plane 418, so that the fixing part 403 is basically roughly positioned. Finally, the fixing part 403 is fixed to the first frame 10 by bolts. After the fixing part 403 is installed, the second positioning hole of the expansion part 404 is aligned with the second positioning column 410, and the end face of the expansion part 404 close to the fixing part 403 contacts the fixing part 403, and then the expansion part 404 is fixed.

[0045] The bolt tightening mechanism 30 is located at a side of the first frame 10 away from the first positioning rod 401 . The bolt tightening mechanism 30 is mainly used to tighten the bolts between the connecting rod body 601 and the connecting rod cover 602 to facilitate subsequent installation.

[0046] like Figure 6 As shown, the bolt tightening mechanism 30 includes a second sliding mechanism and a third sliding mechanism, the second sliding mechanism is mounted on the first frame 10, and the second sliding mechanism is used to control the third sliding mechanism to move along the axis of the fixing portion 403. In order to speed up the process, generally, multiple connecting rods 60 are installed on the first positioning rod 401 and the second positioning rod 402 at one time, so the bolt tightening mechanism 30 needs to be moved back and forth when tightening the bolts.

[0047] The second sliding mechanism includes a second power 301, a second slide rail 302 and a second base plate 303. The fixed ends of the second slide rail 302 and the second power 301 are both installed on the first frame 10. A second slider 304 is installed at the bottom of the second base plate 303. The movable end of the second power 301 is connected to the second slider 304.

[0048] The third sliding mechanism is provided with a bolt tightening member 305, which can be rotated to loosen the bolt. When loosening the bolt, the third sliding mechanism needs to drive the bolt to move rightward, and the third sliding mechanism is used to control the bolt tightening member 305 to move away from the expansion mechanism 40, generally away from the expansion mechanism 40.

[0049] The third bottom plate 306 is arranged on the second bottom plate 303, and the third power 307 and the third slide rail 308 are installed on the second bottom plate 303. The movable end of the third power 307 is connected to the third bottom plate 306, and the third slider 309 cooperating with the third slide rail 308 is installed at the bottom of the third bottom plate 306. A limiting plate 310 is arranged on the side of the second bottom plate 303 close to the expansion mechanism 40, and an anti-collision plate 311 is arranged at the third bottom plate 306 corresponding to the limiting plate 310. When the third power 307 drives the third bottom plate 306 to move toward the limiting plate 310, the anti-collision plate 311 contacts the limiting plate 310, which means that the third bottom plate 306 moves to the limit position, and the contact between the anti-collision plate 311 and the limiting plate 310 can also play a shock-absorbing effect.

[0050] The third bottom plate 306 is provided with a fourth bottom plate 312, and the bolt tightening member 305 is installed on the fourth bottom plate 312. The third bottom plate 306 and the fourth bottom plate 312 can be slidably connected through a fourth slide rail and a fourth slider, and the fourth bottom plate 312 can adjust the relative height with the third bottom plate 306 through a fine adjustment mechanism. An adjustment rod 313 is provided on the third bottom plate 306, and the adjustment rod 313 is rotatably connected with the third bottom plate 306 and the fourth bottom plate 312. For example, when the adjustment rod 313 is rotated clockwise, the third bottom plate 306 moves downward relative to the fourth bottom plate 312, and when the adjustment rod 313 is rotated counterclockwise, the third bottom plate 306 moves upward relative to the fourth bottom plate 312, thereby adjusting the height of the bolt tightening member 305, which is suitable for different models of connecting rods 60. Corresponding marks can also be made on the third bottom plate 306 and the fourth bottom plate 312, and when the marks are aligned, it means that they are suitable for corresponding models.

[0051] In order to prevent the bolt from falling and being lost after the bolt is screwed out by the bolt tightening member 305, a material receiving box 102 is provided on the first frame 10. The material receiving box 102 is located on the side of the expansion mechanism 40 close to the bolt tightening mechanism 30, and the material receiving box 102 is below the connecting rod 60 after it is installed to the second positioning rod 402.

[0052] During the process of marking and tightening the bolts, in order to prevent the connecting rod 60 from moving, a clamping mechanism 50 is installed on the first frame 10. The clamping mechanism 50 is relatively arranged in front of the expansion mechanism 40 and is used to clamp the connecting rod 60 onto the expansion mechanism 40.

[0053] like Figure 7As shown, the clamping mechanism 50 includes a clamping frame 501, a clamping power 502 and a clamping block 503. The clamping frame 501 is mounted on the first frame 10, the fixed end of the clamping power 502 is mounted on the clamping frame 501, and the clamping block 503 is mounted on the movable end of the clamping power 502. In order to ensure the movement of the clamping block 503, two guide shafts 504 are provided on the clamping block 503, and the guide shafts 504 can move with the clamping frame 501. When clamping the connecting rod 60, the clamping block 503 presses the large diameter end of the connecting rod 60 as much as possible, because both the engraving and the expansion are for the large diameter end.

[0054] The first frame 10 is also equipped with a sensor 103, a button and an operation panel 104. Only when the sensor 103 detects that the operator's body part has left the frame, and then selects the corresponding data on the operation panel 104, and finally presses the button, the internal mechanisms start to operate. An indicator light 105 is also installed on the top of the first frame 10.

[0055] Working process: The connecting rod 60 is sleeved onto the first positioning rod 401 and the second positioning rod 402, and the pressing block 503 is extended by the pressing power 502 to press and fix the connecting rod 60, and then the marking machine marks the connecting rod 60. After the marking is completed, the second power 301 of the bolt tightening mechanism 30 moves the bolt tightening member 305 to the position corresponding to the bolt, and the third power 307 moves the bolt tightening member 305 toward one side of the connecting rod body. After the bolt tightening member 305 works to screw off the bolt, the bolt falls into the receiving box 102, and the second power 301 moves the bolt tightening mechanism 30 in turn to tighten all the remaining bolts. Then the pressing power 502 retracts the pressing block 503, and the first power 411 moves the first connecting plate 406 toward one side of the bolt tightening mechanism 30, so that the expansion part 404 drives the connecting rod cover sub-connector to separate.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
