[0001] This invention relates to the technical field of production lines, and specifically to a connecting rod production line. Background Technology

[0002] Connecting rods are commonly used components in hydraulic systems, typically assembled from rectangular or square welded pipes. However, existing equipment requires step-by-step processing, necessitating the use of multiple machines for cutting, flattening and drilling, welding threaded connectors, welding sleeves, drilling oil holes in the sleeves, and deburring. Therefore, this process presents the following problems:

[0003] 1. Each process is carried out manually, resulting in low automation and high costs;

[0004] 2. The square tubes need to be moved manually multiple times during processing, which is time-consuming and results in low production efficiency. Summary of the Invention

[0005] This invention addresses the aforementioned problems and aims to provide a connecting rod production line that enables fully automated production of connecting rods, thereby improving production efficiency and reducing costs.

[0006] To achieve the above objectives, the present invention provides a connecting rod production line for assembling threaded connectors and sleeves onto square tubes, including a frame and a sawing mechanism, a flattening mechanism, a punching mechanism, a welding mechanism, and a deburring mechanism located on the frame;

The flattening mechanism is located at the tail end of the feeding platform and between the feeding platform and the feeding platform. The outlet of the flattening mechanism is connected to the inlet of the feeding platform. The punching mechanism, the welding mechanism and the deburring mechanism are arranged sequentially between the inlet and outlet of the feeding platform.

[0008] The square tube is movably placed on the feeding channel and can move to the flattening mechanism via the sawing mechanism. The feeding platform can drive the square tube to pass sequentially through the punching mechanism, the welding mechanism, and the deburring mechanism; wherein,

[0009] The welding mechanism includes a first welding assembly and a second welding assembly located symmetrically on both sides of the feeding platform.

[0010] According to the above-described connecting rod production line, the feeding platform has a first side and a second side opposite to each other. The inlet of the feeding platform is located on the first side. A drilling station, a first welding station and a second welding station are sequentially provided on the frame outside the first side.

When the lifting cylinder drives the support base plate to rise, the support base plate can drive the square tube and the top frame to rise through the support frame. At this time, the side-shifting cylinder can drive the square tube to move laterally through the support frame.

[0016] According to the above-described connecting rod production line, the support base has multiple spaced first slots on both sides, and the multiple first slots correspond to the drilling station, the first welding station, the second welding station and the deburring station respectively. The top frame has second slots on both sides that correspond one-to-one with the first slots.

The first clamping turntable can drive the square tube to rotate so that both welding holes can face the first welding head.

[0019] When the tail end of the square tube is located at the second welding station, the tail end of the square tube can be inserted into the second clamping turntable, and the second clamping turntable can drive the square tube to rotate so that the tail end of the square tube rotates toward the second welding head.

[0020] According to the above-described connecting rod production line, it further includes a drilling mechanism, and the second welding assembly further includes a second vibratory plate, which is located on one side of the third welding station and is used to provide a sleeve for the second welding assembly. The second welding head is used to weld the sleeve to the head of the square tube.

[0021] The drilling mechanism is disposed between the second welding assembly and the deburring mechanism, and is used to drill holes in the sleeve to form oil holes;

[0022] The deburring mechanism is used to remove burrs from the sleeve.

[0023] According to the above-described linkage production line, the sawing mechanism includes a second positioning component and a sawing component.

The sawing component includes a first support seat that is transferred to the second positioning platform in the middle, a sawing motor fixed in one end of the first support seat, a sawing blade connected to the output shaft of the sawing motor, and a lifting cylinder connected to the other end of the first support seat.

[0024] The connecting rod production line also includes a feeding mechanism, which includes a third positioning component and a driving component. A second guide rail is laid on the feeding channel. The third positioning component includes a third positioning platform that is movably mounted on the second guide rail. The driving component includes a driving cylinder.

It has a high degree of automation, which can greatly improve production efficiency and significantly reduce labor costs. At the same time, the first slot on the support base can support the square tube in the drilling, welding and deburring steps. Meanwhile, a liftable support block can make the square tube disengage from the first slot and move laterally, which not only ensures the support effect of the square tube, but also ensures that the square tube can be automatically moved by the feeding platform to complete each step of automatic processing.

[0040] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the present invention. However, the invention is not limited to these embodiments.

[0041] like Figure 1-3 As shown, a connecting rod production line includes a frame 2 and a feeding mechanism 9, a sawing mechanism 3, a flattening mechanism 4, a drilling mechanism 5, a welding mechanism 6, a drilling mechanism 10, and a deburring mechanism 7 located on the frame 2. It can sequentially perform sawing, flattening of the head of the square tube 1, drilling welding holes at the tail of the square tube 1, welding of threaded connector 11 at the tail of the square tube 1, welding of sleeve 12 at the head of the square tube 1, drilling of oil holes in the sleeve 12, and deburring of the sleeve 12. It can realize the automatic processing of the square tube 1 to obtain the processed connecting rod. It has a high degree of automation, which can reduce labor costs and greatly improve production efficiency.

[0042] Specifically, the frame 2 is provided with a feeding channel and a feeding platform 8. The feeding channel is used to feed the square tube 1, and the feeding platform 8 is used to drive the square tube 1 to pass through the punching mechanism 5, the welding mechanism 6, the drilling mechanism, and the deburring mechanism 7 in sequence. The sawing mechanism 3 is located on one side of the feeding channel, and the flattening mechanism 4 is located at the tail end of the feeding platform and between the feeding platform and the feeding platform 8. The outlet of the flattening mechanism 4 is connected to the inlet of the feeding platform 8. The punching mechanism 5, the welding mechanism 6, and the deburring mechanism 7 are arranged in sequence between the inlet and outlet of the feeding platform 8. After the square tube 1 is fed, it passes through the sawing mechanism 3, the flattening mechanism 4, the punching mechanism 5, the welding mechanism 6, the drilling mechanism, and the deburring mechanism 7 in sequence and is processed in sequence. In this embodiment, after the first square tube 1 passes through the sawing mechanism 3, the second square tube 1 can be fed into the sawing mechanism 3, that is, multiple square tubes 1 can be processed at the same time, further improving the processing efficiency.

[0043] Specifically, a second guide rail 21 is laid on the feeding channel. The feeding mechanism 9 includes a third positioning component and a driving component. The second guide rail 21 is laid on the feeding channel. The third positioning component includes a third positioning platform 91 that is movably mounted on the second guide rail 21. The driving component includes a driving cylinder 92. The piston rod of the driving cylinder 92 is connected to the third positioning platform 91 and can drive the second positioning platform 91 to one side of the sawing mechanism 3. That is, a feeding station can be set on the frame 2. Manual or robot personnel place the initial square tube 1 material onto the third positioning platform 91 at the feeding station. In this embodiment, the third positioning platform 91 is equipped with a clamping component and a clamping cylinder. The clamping cylinder drives the clamping component to position the square tube 1, and the driving cylinder 92 drives the third positioning platform 91 to move on the second guide rail 21 and drive it to one side of the sawing mechanism 3. Then, the square tube 1 is placed into the sawing mechanism 3.

[0044] Specifically, the sawing mechanism 3 includes a second positioning component and a sawing component. The second positioning component includes a second positioning platform 311 on which the square tube 1 can be placed. The sawing component includes a first support 321 connected in the middle to the second positioning platform 311, a sawing motor fixed in one end of the first support 321, a sawing blade 322 connected to the output shaft of the sawing motor, and a lifting cylinder 323 connected to the other end of the first support 321. Similarly, the second positioning platform 311 is also equipped with... The clamping component is used to clamp the square tube 1 to prevent the square tube 1 from moving during the cutting process. When the sawing motor drives the sawing blade 322 to rotate, only one end of the first support base 321 needs to be driven to rise by the lifting cylinder 323, and the other end will drive the sawing blade 322 to fall, so as to saw the square tube 1 located on the second positioning platform 311 to obtain the square tube 1 of the preset length. After sawing, the head of the square tube 1 is flattened by the flattening mechanism 4, and the tail of the square tube 1 is punched by the punching mechanism 5.

[0045] Specifically, the feeding platform 8 has a first side and a second side, with the inlet of the feeding platform 8 located on the first side. The welding mechanism 6 includes a first welding assembly and a second welding assembly 62 located symmetrically on both sides of the feeding platform 8. The first welding assembly is located on the first side of the feeding platform 8, and the second welding assembly 62 is located on the second side of the feeding platform 8. The first welding assembly includes a first welding head 611 and a second welding head 612, and the second welding assembly 62 includes a third welding head 621. A drilling station, a first welding station, and a second welding station are sequentially provided on the frame 2 on the outer side of the first side, and a third welding station and a deburring station are sequentially provided on the frame 2 on the outer side of the second side. The workstation is located on one side symmetrical to the first welding workstation. The drilling mechanism 5 is located at the drilling workstation, the first welding head 611 is located at the first welding workstation, the second welding head 612 is located at the second welding workstation, and the third welding head 621 is located at the third welding workstation. The first welding head 611 is used to weld the part of the threaded connector 11 corresponding to the welding hole. The second welding head 612 is used to weld the circumferential gap between the tail end of the square tube 1 and the threaded connector 11. The third welding head 621 is used to weld the head of the square tube 1 and the sleeve 12. Since the third welding workstation is located on one side symmetrical to the first welding workstation, the welding actions of the head and tail of the square tube 1 can be performed simultaneously from both sides, thereby improving its working efficiency.

[0046] Specifically, the punching mechanism 5 includes a fixed base 51 and a stamping assembly. The stamping assembly includes a stamping cylinder fixed on the stamping base, a stamping platform 521 movably disposed below the stamping base via the stamping cylinder, and a stamping head 522 fixed below the stamping platform 521. When the feeding platform 8 drives the tail end of the square tube 1 to the punching station, the stamping head 522 can descend to punch the square tube 1 and form welding holes on both symmetrical sides of the tail end of the square tube 1. During the forming process of the welding holes, the stamping cylinder drives the stamping platform 521 to descend, and the stamping platform 521 drives the stamping head 522 to descend. The stamping head 522 punches the square tube 1 and punches welding holes on both symmetrical sides of the tail end of the square tube 1 to ensure the stability of the welding.

[0047] Specifically, the flattening mechanism 4 includes a first positioning component and a pressing component. The first positioning component includes a first positioning platform 411 and a first clamping seat disposed on the first positioning platform 411. The pressing component includes a pressing cylinder fixed on the stamping seat and a pressing head 421 with one end connected to the piston rod of the pressing cylinder. When the square tube 1 moves into the first clamping seat through the sawing mechanism 3, the pressing head 421 can descend to press down the head of the square tube 1. The head of the square tube 1 can only be used for welding the sleeve 12 after being flattened.

[0048] In order to provide a threaded connector 11 for the first welding assembly and a sleeve 12 for the second welding assembly 62, the first welding assembly also includes a first vibratory plate 614, which is located on one side of the first welding station and is used to provide the threaded connector 11 for the first welding assembly. The second welding assembly 62 also includes a second vibratory plate 622, which is located on one side of the third welding station and is used to provide the sleeve 12 for the second welding assembly 62.

[0049] Specifically, the feeding platform 8 includes a support assembly and a lateral shifting assembly. The support assembly includes a support base 811 fixed to the top of the frame 2, a support base plate 812 located within the support base 811, and a lifting cylinder located at the bottom of the frame 2. The lateral shifting assembly includes a support frame 821 slidably mounted on the support base plate 812 via a first guide rail, a top frame 822 movably mounted above the support base 811, and a lateral shifting cylinder 823 fixed to one end of the support base 811. The piston rod of the lifting cylinder is connected to the support base plate 812. The bottom is connected, and the piston rod of the lateral displacement cylinder 823 is connected to one end of the support frame 821. When the lifting cylinder drives the support base plate 812 to rise, the support base plate 812 can drive the square tube 1 and the top frame 822 to rise through the support frame 821. At this time, the lateral displacement cylinder 823 can drive the square tube 1 to move laterally through the support frame 821. That is, in this embodiment, the square tube 1 can be driven to rise, and the top frame 822 can be lifted through the square tube 1. At this time, the lateral displacement cylinder 823 can drive the square tube 1 to move laterally through the support frame 821 to adjust the position of the square tube 1.

[0050] To ensure the stability of the square tube 1 during processing, multiple first slots are provided on both sides of the support base 811 at intervals. The multiple first slots correspond to the drilling station, the first welding station, the second welding station, and the deburring station, respectively. The top frame 822 is provided on both sides with second slots that correspond one-to-one with the first slots. When the top frame 822 is placed on the support base 811, the first slots and the second slots together form a circular limiting groove. Both ends of the square tube 1 can be inserted into the limiting groove. The limiting groove restricts the large-scale movement of the square tube 1. At the same time, the support base 811 can provide support for the square tube 1 during the drilling, welding, and deburring processes to ensure processing accuracy.

[0051] To ensure the smooth movement of the square tube 1, multiple sets of symmetrical support blocks 821a are provided on both sides of the support frame 821. A third slot 821b is provided on the support block 821a. When the lifting cylinder drives the support base plate 812 to rise, the support base plate 812 can drive the support blocks 821a to rise. Both ends of the multiple square tubes 1 can be inserted into the third slot 821b, and the support blocks 821a can drive the square tube 1 to disengage from the first slot. That is, when the lifting cylinder drives the support base plate 812 to rise, the support base plate 812 can drive the support frame 821 to rise, which in turn drives the support blocks 821a located on both sides of the support frame 821 to rise synchronously. During the rising process, the support blocks 821a will connect with both ends of the square tube 1 and drive the square tube 1 to rise. When the square tube 1 rises to disengage from the first slot, the side-shifting cylinder 823 can drive the support frame 821 to move the square tube 1 laterally to adjust the processing position.

[0052] To achieve the positioning and multi-angle welding of the square tube 1, the first welding assembly also includes a first clamping turntable 613 located at the first welding station and a second clamping turntable 615 located at the second welding station. When the tail end of the square tube 1 is located at the first welding station, the tail end of the square tube 1 can be inserted into the first clamping turntable 613 to position the square tube 1. The first clamping turntable 613 can drive the square tube 1 to rotate so that both welding holes can face the first welding head 611, thus achieving welding at both welding holes and ensuring the stability of the initial welding. When the tail end of the square tube 1 moves to the second welding station, the tail end of the square tube 1 can be inserted into the second clamping turntable 615. The second clamping turntable 615 can drive the square tube 1 to rotate so that the tail end of the square tube 1 rotates towards the second welding head 612, thereby achieving circumferential welding of the tail end of the square tube 1.

[0053] Specifically, the drilling mechanism 10 is located between the second welding assembly 62 and the deburring mechanism 7, and is used to drill holes in the sleeve 12 to form oil holes. After the oil holes are processed, the deburring mechanism 7 removes the burrs in the sleeve 12 to meet the finished product requirements. In this embodiment, the deburring mechanism 7 removes the burrs in the sleeve 12 by pressing the deburring ball into the sleeve 12.
