Description

Technical Field

[0001] The invention belongs to the technical field of processing parts of marine diesel engines, and in particular relates to a finishing device for a connecting rod of a marine diesel engine. Background Art

[0002] The connecting rod processing process can be roughly divided into the rough machining stage, the semi-finishing stage and the finishing stage. The finishing stage is mainly aimed at the connecting rod surface, that is, it is achieved on the basis of the large and small head holes meeting the standards, such as fine filing of the small head piston pin bearing hole and honing of the large head hole.

[0003] At present, the finishing stage has high requirements for connecting rod processing. During the clamping and fixing processing, the lack of calibration components can easily cause the connecting rod to shift, resulting in deviations in the processing hole position, which affects the processing quality of the connecting rod and reduces the processing efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a marine diesel engine connecting rod finishing device in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A finishing device for a connecting rod of a marine diesel engine comprises a base, a driving processing assembly connected to the base, and a processing table connected to the base;

[0007] It also includes an anti-deviation mechanism, which includes a detection component for connecting rod deviation detection, a fine-tuning component, a sliding seat connected to both sides of the processing table surface, and a left clamping rod and a right clamping rod connected to the inner sides of the two sliding seats.

[0008] Wherein: when the detecting assembly detects that the connecting rod is offset during processing, the detecting assembly uses the fine-tuning assembly to fine-tune the left clamping rod and the right clamping rod that fix the connecting rod.

[0009] A further improvement is that the fine-tuning assembly includes a drive box connected to the side of each sliding seat, a stepping motor connected to each drive box, a fine-tuning rod 1 and a fine-tuning rod 2 running through each sliding seat, and a swash plate sleeved on the main shaft of each stepping motor, one end of the fine-tuning rod 1 and the fine-tuning rod 2 is connected to the swash plate, and the other end is movably connected to the left clamping rod and the right clamping rod respectively, two compression springs are connected to the side of each of the sliding seats, each compression spring is respectively sleeved on the fine-tuning rod 1 and the fine-tuning rod 2, two adjusting and fastening screws are passed through the threads on both sides of the base, and the end of each of the adjusting and fastening screws is movably connected to the side of the sliding seat respectively;

[0010] After the connecting rod is offset, the conductive sheet 1 on the left clamping rod and the right clamping rod contacts the conductive sheet 2 on the sliding seat, and the two stepper motors are started at the same time. The stepper motor on the left drives the swash plate to rotate clockwise, so that the fine-tuning rod 1 pushes the left clamping rod closer to the right clamping rod, and the stepper motor on the right drives the swash plate to rotate counterclockwise, and the fine-tuning rod 1 on the right moves the position of the fine-tuning connecting rod to the right.

[0011] A further improvement is that the detection assembly includes a conductive sheet 1 embedded on both sides of the inner wall of each sliding seat, a signal lamp connected to the base, and a conductive sheet 2 embedded in the left clamping rod and the right clamping rod, the output ends of the conductive sheet 1 and the conductive sheet 2 are electrically connected to the positive and negative electrodes of the signal lamps respectively, and a pointing rod is connected to the middle of the processing table;

[0012] During the processing, if the connecting rod deviates left or right, the conductive sheet 2 arranged on the left clamping rod and the right clamping rod will contact the conductive sheet 1 on the sliding seats on both sides to light up the signal light.

[0013] A further improvement is that the device also includes a sliding fixing assembly, which includes a pushing cylinder connected to one side of the base, a sliding clamping block slidably connected to one side of the processing table surface, a fixed clamping block connected to the other side of the processing table surface, and a clamping sleeve connected to the fixed clamping block and the sliding clamping block. The telescopic rod end of the pushing cylinder is fixedly connected to the sliding clamping block. When in use, the pushing cylinder is started and the sliding clamping block is pushed toward the fixed clamping block by the pushing cylinder to fix the connecting rod.

[0014] A further improvement is that the sliding and fixing assembly also includes a fixing stud threadedly connected to the sliding clamp block and the fixed clamp block at the same side end for fixing the ferrule. The inner wall surfaces of the sliding clamp block and the fixed clamp block are provided with slots. When in use, a ferrule of appropriate size is selected, and the ferrules are inserted into the slots respectively and fixed by the fixing stud to achieve fixation of the small ends of connecting rods of different sizes.

[0015] A further improvement is that the driving processing assembly includes a driving motor, two pulleys, an assembly disk, a sliding lifting seat, a base plate and an electric guide rail.

[0016] A further improvement is that the processing table is provided with corresponding guide grooves for the sliding of the left clamping rod, the right clamping rod, the sliding seat and the sliding clamping block.

[0017] A further improvement is that a limiting groove is provided on the side surface of each swash plate, and the ends of the fine-tuning rod 1 and the fine-tuning rod 2 on both sides are respectively slidably connected to the limiting groove.

[0018] The beneficial effects of the present invention are:

[0019] 1) In the present invention, the design of the pointing rod and the adjusting and fastening screw enables precise calibration and fixation of the connecting rod. The detection component provided can detect the offset of the connecting rod, thereby preventing offset during processing. At the same time, the design of the fine-tuning component can automatically fine-tune after offset occurs, ensuring the smooth operation of the connecting rod processing operation.

[0020] 2) In the present invention, through the design of the sliding clamp, the pushing cylinder, the fixed clamp, the ferrule, the fixed stud and the slot, the small ends of the connecting rods of different sizes can be automatically fixed, thereby cooperating with the use of the anti-drift mechanism to prevent the occurrence of drift. It has the characteristics of reasonable structural design, convenient operation, high processing efficiency and high processing quality. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Example 1

[0033] Combined with attachment Figure 1 、 2 A finishing device for a connecting rod of a marine diesel engine comprises a base 3, a driving processing assembly 2 connected to the base 3, and a processing table 4 connected to the base 3.

[0034] It also includes an anti-deviation mechanism 5, which includes a fine-tuning component 54, a sliding seat 53 connected to both sides of the surface of the processing table 4, a left clamping rod 55 and a right clamping rod 56 rotatably connected to the inner sides of the two sliding seats 53, and a detection component connected to the sliding seat 53, the left clamping rod 55 and the right clamping rod 56.

A stepper motor 542 is connected to each drive box 541, a fine-tuning rod 1 543 and a fine-tuning rod 2 544 are passed through each sliding seat 53, and a swash plate 545 is sleeved on the main shaft of each stepper motor 542. One end of the fine-tuning rod 1 543 and the fine-tuning rod 2 544 is connected to the swash plate 545, and the other end is movably connected to the left clamping rod 55 and the right clamping rod 56 respectively. Two compression springs 547 are connected to the side of each sliding seat 53, and each compression spring 547 is sleeved on the fine-tuning rod 1 543 and the fine-tuning rod 2 544 respectively.

[0035] During use, the worker places the connecting rod on the processing table 4 and simultaneously rotates the adjusting and fastening screws 52 on both sides, so that the sliding seats 53 on both sides, together with the left clamping rod 55 and the right clamping rod 56, move closer to each other to clamp the connecting rod. At this time, the adjusting and fastening screws 52 are used to fine-tune the connecting rod in conjunction with the pointing rod 51 to achieve precise calibration of the connecting rod.

[0036] During the machining process, if the connecting rod deviates left or right, the conductive sheet 2 58 provided on the left clamping rod 55 and the right clamping rod 56 will contact the conductive sheet 1 57 on the two side sliding seats 53, and the signal light 59 will light up, thereby realizing the deflection detection of the connecting rod, preventing the deflection during machining, and ensuring the machining quality of the connecting rod;

[0037] It should be noted that the two conductive sheets 58 on the same side of the left clamping rod 55 and the right clamping rod 56 are numbered as No. 1 and No. 2, respectively, corresponding to the Figure 2 , the side close to the sliding fixing component 1 is number two;

[0038] After the connecting rod is deflected, if the conductive piece 1 57 numbered on the left clamping rod 55 contacts the conductive piece 2 58 on the sliding seat 53, and the conductive piece 1 57 numbered on the right clamping rod 56 contacts the conductive piece 2 58 on the sliding seat 53, that is, Figure 2 If the upper part is offset to the left, the staff will start the two stepper motors 542 at the same time, and use the left stepper motor 542 to drive the swash plate 545 to rotate clockwise, so that the fine-tuning rod 1 543 pushes the left clamping rod 55 closer to the right clamping rod 56, and the right stepper motor 542 drives the swash plate 545 to rotate counterclockwise, and the right fine-tuning rod 1 543 moves the position of the fine-tuning connecting rod to the right; conversely, the right stepper motor 542 drives the swash plate 545 to rotate clockwise, so that the fine-tuning rod 1 543 pushes the right clamping rod 56 closer to the left clamping rod 55, and the left stepper motor 542 drives the swash plate 545 to rotate counterclockwise, and the left fine-tuning rod 1 543 moves to the right for fine-tuning, so as to achieve re-calibration of the connecting rod, ensure the processing quality of the connecting rod, and improve the processing efficiency.

When the inclined plate 545 rotates, the fine-tuning rod 1 543 and the fine-tuning rod 2 544 slide in the limiting groove 546, making the sliding more stable.

The rotating shaft of the assembly disk 23 is docked with the pulley 22. When in use, processing equipment can be installed in the middle of the assembly disk 23 and the sliding lifting seat 24 respectively. As the driving motor 21 drives the two pulleys 22, the assembly disk 23 and the processing equipment to rotate, and under the action of the electric guide rail 25, the sliding lifting seat 24 and the processing equipment are driven up and down to achieve processing of the connecting rod.
