Its main function is to transmit the power of the engine to the wheels together with the gearbox and drive axle, so that the car can generate driving force; the traditional automobile transmission shaft processing technology mainly includes casting, forging and machining. Among them, the machining process is to process the raw material (i.e. cylindrical bar) through lathes, milling machines, drilling machines and other processing tools to form it. Since the sizes of automobile transmission shafts of different models are different, the bar needs to be cut to a fixed length before processing.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention Figure 1-Figure 6 As shown, a car transmission shaft bar cutting machine is designed. By setting a clamping and conveying mechanism 3 to cooperate with a cutting component 4, a material receiving component 5 and a conveying component 6, the division of labor between the cutting process and the loading and unloading process is realized without affecting each other, thereby ensuring continuous cutting of the bar 100 and improving the cutting efficiency.

[0035] like Figure 1As shown, the above-mentioned cutting machine includes two groups of symmetrically arranged rails 1 installed on the production line, and a gantry 2 is arranged on the two groups of rails 1. A clamping and conveying mechanism 3 is arranged inside the gantry 2. A flexibly adjustable cutting component 4 is arranged at one end between the two groups of rails 1, and material receiving components 5 are symmetrically arranged at both ends of the cutting component 4. The material receiving components 5 extend outward, and a conveying component 6 is arranged at the other end between the two groups of rails 1 for inputting the bar material 100 to be cut, wherein the material receiving component 5 and the conveying component 6 are respectively arranged corresponding to one end of the clamping and conveying mechanism 3.

[0036] The cutting of the bar material 100 is achieved by the cooperation between the clamping and conveying mechanism 3 and the cutting component 4. At the same time, the cutting component 4 can move flexibly to meet the cutting requirements of different lengths. The further loading process is coordinated by the clamping and conveying mechanism 3 and the conveying component 6, and does not affect the cutting process. The unloading process is coordinated by the clamping and conveying mechanism 3 and the receiving component 5, which also does not affect the cutting process. The multiple stations of the clamping and conveying mechanism 3 operate independently, so that loading and unloading have no effect on cutting, realizing efficient continuous processing and improving the overall cutting efficiency.

[0037] In addition, by placing the bar 100 at the top and the cutting assembly 4 at the bottom, when the cutting assembly 4 cuts the bar 100, waste chips fall due to gravity and cannot gather in the cutting groove, which has little impact on the cutting wheel 47 of the cutting assembly 4, thereby improving the cutting accuracy and the flatness of the cutting surface.

[0038] Further Figure 1 and Figure 2 As shown, the above-mentioned gantry 2 includes a gantry body 21 installed on the track 1, wherein the gantry body 21 can move on the track 1 by being driven by a motor, and slide grooves 22 are symmetrically opened on two side surfaces inside the gantry body 21, and an adjusting screw 23 is rotatably arranged in the slide groove 22, and an adjusting motor 24 is symmetrically arranged at both ends of the top of the gantry body 21, and the output shaft of the adjusting motor 24 is connected to the adjusting screw 23, and the adjusting screw 23 is driven to rotate by the adjusting motor 24, and the adjusting screws 23 on both sides are matched and connected with the clamping and conveying mechanism 3 to realize the upper and lower position adjustment of the clamping and conveying mechanism 3.

[0039] Further Figure 1-Figure 3As shown, the above-mentioned clamping and conveying mechanism 3 includes a connecting cross plate 31 threadedly connected to the two adjusting screws 23, and the inner sides of the two connecting cross plates 31 are fixed with fixed plates 32, and a plurality of transmission rollers 33 are rotatably connected between the two fixed plates 32, and the plurality of transmission rollers 33 are connected by a crawler 34 for transmission, wherein a driving motor (not shown in the figure) is arranged on the fixed plate 32 on one side, and the driving motor is connected to one of the transmission rollers 33 to drive the transmission roller 33 to rotate, wherein a plurality of clamping systems are arranged at equal intervals on the crawler 34, and each clamping system includes two groups of first clamping components 35 and two groups of second clamping components 36 symmetrically arranged, wherein the first clamping component 35 is arranged on the outside of the second clamping component 36, and the first clamping component 35 is arranged in cooperation with the second clamping component 36 to achieve stable clamping of the bar 100, thereby achieving stable cutting of the bar 100.

[0040] Furthermore, multiple groups of clamping systems operate independently of each other without interfering with each other. That is, when the clamping system corresponding to the cutting component 4 position is in operation, the clamping systems corresponding to the conveying component 6 and the material receiving component 5 positions also operate synchronously and independently, avoiding the loading and unloading process causing the cutting to be suspended, thereby reducing the cutting efficiency.

[0041] Further, the running direction from the conveying component 6 to the receiving component 5 is the conveying direction of the clamping conveying mechanism 3, wherein the conveying component 6 corresponds to the first clamping system at the bottom of the clamping conveying mechanism 3 along the conveying direction, the receiving component 5 corresponds to the last clamping system, and the cutting component 4 corresponds to the penultimate clamping system. Figure 2 shown.

[0042] Further Figure 3 As shown, the above-mentioned first clamping assembly 35 includes a connecting column 1 351 connected to the track 34, a cylinder 1 352 is installed at the bottom of the connecting column 1 351, the telescopic rod of the cylinder 1 352 is connected to the rotating cylinder 353, and the rotating cylinder 353 is connected to the manipulator 1 354, and the second clamping assembly 36 includes a connecting column 2 361 connected to the track 34, a cylinder 2 362 is installed at the bottom of the connecting column 2 361, and the telescopic rod of the cylinder 2 362 is connected to the manipulator 2 363, and the manipulator 1 354 and the manipulator 2 363 are driven to move vertically by driving the cylinder 1 352 and the cylinder 2 362.

[0043] When loading, the corresponding clamping system is driven to make the first clamping assembly 35 and the second clamping assembly 36 move downward synchronously, and the bar material 100 located on the conveying assembly 6 is clamped by the manipulator 1 354 and the manipulator 2 363, and the clamping system is reset after clamping;

[0044] When cutting, the clamping system holding the bar 100 and corresponding to the cutting assembly 4 starts the cylinder 1 352 and the cylinder 2 362 to drive the bar 100 to move downward for cutting;

[0045] When unloading, the two cut sections of bar material 100 are moved to the corresponding position of the material receiving component 5 under the drive of the crawler 34, the robot arm 2 363 releases the bar material 100, and the second clamping component 36 is reset, and the rotating cylinders 353 on both sides are started to drive the corresponding robot arm 1 354 to rotate ninety degrees clockwise, adjust the horizontal cut bar material 100 to the longitudinal direction, and continue to move down to the mouth of the material receiving component 5, release it into the material receiving component 5, and the first clamping component 35 is reset after release.

[0046] Further Figure 4 As shown, the above-mentioned cutting assembly 4 includes a mobile base 41 installed on the ground, a mounting groove 42 is opened at the bottom of the mobile base 41, a mobile groove 43 is opened at the top of the mounting groove 42, and the mobile groove 43 passes through the top surface of the mobile base 41, and a mobile screw 44 is rotatably arranged in the mounting groove 42, a cutting base 45 is threadedly connected to the mobile screw 44, and the cutting base 45 is arranged through the mobile groove 43, and further, telescopic covers 46 are arranged on both sides of the cutting base 45 and on the mobile groove 43, and a cutting wheel 47 and a cutting motor 48 are installed on the cutting base 45, and the driving shaft of the cutting motor 48 is connected to the cutting wheel 47 to drive the cutting wheel 47 to rotate for cutting processing.

[0047] Furthermore, a moving motor 412 is provided on the outer side of the moving base 41, and the driving shaft of the moving motor 412 is connected to the driving gear 411, and a transmission gear 410 is provided on one side of the moving screw 44, and the transmission gear 410 is meshingly connected with the driving gear 411. The driving gear 411 is driven to rotate by the moving motor 412, and the driving gear 411 drives the transmission gear 410 to rotate, thereby driving the moving screw 44 to rotate, thereby realizing the lateral movement of the cutting base 45.

[0048] Furthermore, according to the size of the bar 100 that needs to be cut, the moving motor 412 is started to drive the cutting wheel 47 to move horizontally and adjust it to a suitable cutting position for processing. When the cutting wheel 47 interferes with any one of the two groups of second clamping components 36, the second clamping component 36 at the interfering position is reset and no clamping is performed.

[0049] Further Figure 5 As shown, the material receiving assembly 5 comprises a material receiving box 51, the bottom of which is provided with running wheels for convenient transportation, a material receiving cavity 52 is provided inside the material receiving box 51, a blocking portion 53 is provided at the top of the material receiving cavity 52 to buffer the impact force of the bar material 100 falling, and the mouth of the material receiving box 51 is divided into a discharge port 58 and a feed port 59 by the blocking portion 53, wherein a guide seat 57 is provided near the side of the feed port 59, and the position of the feed port 59 corresponds to the longitudinal position of the cut bar material 100;

[0050] Furthermore, an adjusting bottom plate 54 is provided at the bottom of the receiving cavity 52, and airbag 1 55 and airbag 2 56 are provided between the adjusting bottom plate 54 and the bottom surface of the receiving cavity 52, wherein airbag 1 55 and airbag 2 56 are connected to an external air source, and the adjusting bottom plate 54 can be tilted left and right by inflating and deflating air in airbag 1 55 and airbag 2 56, thereby arranging the rod material 100 entering the receiving cavity 52 so that it can be laid flat and neatly.

[0051] Further Figure 2 As shown, the conveying assembly 6 is a conveying structure in the prior art, which includes a conveying shaft and a conveyor belt structure, and a card seat is arranged on the conveyor belt for supporting the bar material 100.

[0052] Furthermore, when the manipulator 1 354 and the manipulator 2 363 of the corresponding clamping system clamp the bar 100 from the conveying component 6, the mechanical clamping action easily causes a slight offset of the clamping position of the bar 100. In order to avoid the influence of the offset and ensure the processing accuracy, a positioning plate 11 is connected to the inner side of the track 1, and a connecting plate 12 is arranged on the positioning plate 11, and the position of the connecting plate 12 corresponds to the cutting component 4. An infrared rangefinder 13 is arranged on the connecting plate 12, and the two infrared rangefinders 13 are symmetrically arranged. Further, infrared rangefinders 2 49 are symmetrically arranged on both sides of the top of the cutting base 45, and a PLC controller is arranged on the gantry 2;

[0053] Positioning is performed before cutting, and the corresponding clamping system drives the bar 100 to move down to the position corresponding to the infrared rangefinder 13. The infrared rangefinders 13 on both sides measure the distance between the two ends of the bar 100 and its body. Figure 6 As shown, the distance between the side of the left end bar 100 and the infrared rangefinder 13 is H1, and the distance between the side of the right end bar 100 and the infrared rangefinder 13 is H2;

[0054] At the same time, the distances to the surfaces of the positioning plates 11 on both sides are measured by the infrared rangefinder 2 49, and the distances between the left infrared rangefinder 2 49 and the surface of the left positioning plate 11 are set to H3, and the distances between the right infrared rangefinder 2 49 and the surface of the right positioning plate 11 are set to H4;

[0055] The infrared rangefinder 13 and the surface of the positioning plate 11 are located in the same plane, ensuring that H1+H2+the length of the bar 100=H3+H4+the distance between the two infrared rangefinders 49;

[0056] By transmitting the measured data H1, H2, H3 and H4 to the PLC controller, the position where the cutting assembly 4 needs to be offset is calculated.

[0057] When the bar 100 needs to be divided into two equal lengths, the offset position L1 = ((H4-H3)-(H2-H1)) / 2, wherein when L1 is a negative number, it is offset to the left by a distance of |L1|, and when L1 is a positive number, it is offset to the right by a distance of |L1|;

[0058] When the bar 100 needs to be cut to a fixed length, the offset position L2=L3-((H3-H1)+X), where X is the distance from the infrared rangefinder 49 to the vertical axis position of the cutting wheel 47, and the data is manually measured before processing, and L3 is the manually set required length, where when L2 is a negative number, it is offset to the left by a distance of |L2|, and when L2 is a positive number, it is offset to the right by a distance of |L2|;

[0059] When the present invention is used, the external bar 100 is transported to the inside through the conveying component 6. When it is transported to the first clamping system of the clamping conveying mechanism 3 along the conveying direction, the cylinder 1 352 and the cylinder 2 362 of the clamping system are started to drive the manipulator 1 354 and the manipulator 2 363 to move downward to clamp the bar 100. After clamping, the bar 100 is driven to rise and reset. Then, the bar 100 is clamped in sequence with the conveying component 6 along the crawler 34. When the clamping system holding the bar 100 moves to the top of the cutting component 4, the cylinder 1 352 and the cylinder 2 362 of the clamping system are started to drive the bar 100 to move downward to the positions corresponding to the infrared rangefinder 13 at both ends. The position where the cutting component 4 needs to be offset is calculated by the PLC controller, and the moving motor 412 is started to drive the moving screw 44 to rotate, thereby driving the cutting wheel 47 to move to the corresponding position. Then, the cylinder 1 352 and the cylinder 2 of the clamping system are started. 362 drives the bar 100 to continue to move downward and contact with the cutting wheel 47 for cutting. After cutting, the crawler 34 drives the cut bar 100 to move above the material receiving assembly 5, and then the manipulator 2 363 releases the bar 100, and the second clamping assembly 36 is reset, and the rotating cylinders 353 on both sides are started to drive the corresponding manipulator 1 354 to rotate ninety degrees clockwise, and the horizontal cut bar 100 is adjusted to the longitudinal direction, and continues to move downward to the mouth of the material receiving assembly 5, and is released into the material receiving assembly 5. After release, the first clamping assembly 35 is reset, and the clamping system continues to move with the crawler 34. The bar 100 that falls into the material receiving assembly 5 is guided by the guide seat 57, enters the material receiving cavity 52 and is placed on the adjusting bottom plate 54, and is connected to the external air source. By continuously filling and deflating the airbag 1 55 and the airbag 2 56, the airbag 1 55 and the airbag 2 56 are expanded and contracted, driving the adjusting bottom plate 54 to deflect, and the bar 100 is sorted.
