[0002] The yoke is generally used on the transmission shaft. It is a widely used universal transmission component when matched with the cross shaft. The universal yoke is a U-shaped block structure, including a fork foot and a mounting head. Two ear holes on the same axis are opened in the fork foot.

DETAILED DESCRIPTION

[0030] 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.

[0031] As introduced in the background technology, the deficiencies in the prior art exist. In order to solve the above technical problems, the present application proposes a multi-station combined processing equipment for automobile steering shaft yoke.

[0032] Example 1

[0033] In a typical implementation of the present application, Figure 1 As shown, a multi-station combined processing equipment for a steering shaft yoke of an automobile comprises a machine body 1, a processing mechanism 2 arranged on the machine body 1, and a conveying mechanism 3 arranged on the machine body 1, wherein the processing mechanism 2 comprises a ball nut rack 26 and a processing head 28, wherein a plurality of ball nut racks 26 are movably arranged on the machine body 1, and the ball nut racks 26 are evenly distributed on the machine body 1 in a straight line, and the ball nut racks 26 reciprocate up and down in a straight line, and the ball nut racks 26 are all provided with processing heads 28, and the processing heads 28 are located at the bottom end of the ball nut racks 26, and the processing heads 28 are used for processing work;

[0034] The conveying mechanism 3 includes a rail frame 31 and a limit clamp 36. The rail frame 31 is fixedly installed on the machine body 1. The rail frame 31 is located directly below the overall processing head 28. Each processing head 28 is a processing station. The rail frame 31 is a double-rail structure. The middle part of the rail frame 31 is an arc structure. The arc structure of the rail frame 31 corresponds to the processing station of the middle processing head 28. When the steering shaft yoke moves to the arc structure position on the rail frame 31, the steering shaft yoke flips 180 degrees and then continues to be conveyed and moved on the rail frame 31. A limit clamp 36 is arranged on the rail frame 31. The limit clamp 36 moves on the rail frame 31. The steering shaft yoke is arranged on the limit clamp 36. The limit clamp 36 can be removed from the rail frame 31.

[0035] When using the present invention:

[0036] The steering shaft yoke is placed on the limiting clamp 36, and the limiting clamp 36 carries the steering shaft yoke to move on the rail frame 31. When the limiting clamp 36 moves to the bottom of a processing head 28, the limiting clamp 36 stops moving, and the ball nut frame 26 is started. The ball nut frame 26 drives the processing head 28 to move, and the processing head 28 is started to rotate, so that the processing head 28 is pressed against the steering shaft yoke on the limiting clamp 36, so that the processing head 28 processes the steering shaft yoke, and then the limiting clamp 36 is continued to be moved on the rail frame 31, and the limiting clamp 36 is stopped. The clamping member 36 is flipped under the influence of the shape of the rail frame 31, so that the limit clamping member 36 drives the steering shaft yoke to flip 180 degrees, so that the steering shaft yoke is turned over and processed at the next workstation until the steering shaft yoke is processed and removed from the rail frame 31, thereby replacing the transmission effect of the robot arm on the yoke, reducing the cost of using the processing equipment, and utilizing the preset direction of the rail frame 31 to enable the yoke to complete the flipping and other actions at a fixed position, thereby simplifying the cumbersome process brought about by the program-controlled robot arm operation and improving the working efficiency of the processing equipment.

[0037] Example 2

[0038] like Figure 2-Figure 4 As shown, the processing mechanism 2 also includes a column 21, and a plurality of columns 21 are fixedly installed on the plurality of bodies 1. The number of the columns 21 is the same as the number of the processing heads 28. The columns 21 are evenly distributed on the body 1 in a straight line. The columns 21 are rotatably matched with screws 22. The screws 22 are located above the rail frame 31. The axes of the screws 22 are arranged up and down. Stepper motors 23 are fixedly installed on the tops of the columns 21, and the stepper motors 23 are power-connected to the screws 22.

[0039] Furthermore, the difference from the above-mentioned embodiment lies in that a slide rail 24 is fixedly mounted on each column 21, the slide rail 24 has the same length as the screw rod 22, the slide rail 24 and the screw rod 22 are located at the same height, a slide plate 25 is slidably fitted on each slide rail 24, the slide plate 25 is adjacent to the screw rod 22, the ball nut frame 26 is adapted to the screw rod 22, the screw rod 22 passes through the ball nut frame 26, the screw rod 22 is meshed with the ball nut frame 26, and the ball nut frame 26 is fixedly connected to the slide plate 25.

[0040] Furthermore, the difference from the above-mentioned embodiment lies in that a processing motor 27 is fixedly mounted on the ball nut frame 26 , the shaft of the processing motor 27 faces downward, and a processing head 28 is fixedly mounted on the shaft of the processing motor 27 .

[0041] When processing is performed, the stepper motor 23 is started, and the stepper motor 23 drives the screw 22 to rotate on the column 21, so that the screw 22 drives the ball nut frame 26 to move, and the ball nut frame 26 is connected to the slide plate 25 so that the slide plate 25 moves on the slide rail 24, thereby moving the ball nut frame 26, and the ball nut frame 26 drives the processing motor 27 to move, and the processing motor 27 drives the processing head 28 to move, and the processing motor 27 is started, and the processing motor 27 drives the processing head 28 to rotate, so that the processing head 28 performs processing work.

[0042] Furthermore, the difference from the above-mentioned embodiment lies in that a control console 29 is fixedly mounted on the machine body 1, the control console 29 is used to control the operation of the processing equipment, and an unqualified product box 210 is provided on the machine body 1, the unqualified product box 210 is located at the bottom end of the machine body 1, the top end of the unqualified product box 210 is an open end, and the unqualified product box 210 is used to place unqualified steering shaft yokes.

[0043] Example 3

[0044] like Figure 5-Figure 8 As shown, the conveying mechanism 3 also includes conveying rollers 32. A plurality of conveying rollers 32 are rotatably matched at both ends of the track frame 31. The conveying rollers 32 are symmetrically distributed on the double tracks of the track frame 31. The conveying rollers 32 are located between the tracks on both sides of the track frame 31. The axes of the conveying rollers 32 pass through the track frame 31. Toothed belts 33 are tensioned on the axes of the conveying rollers 32 on both sides of the two ends. The toothed belts 33 are meshed with the axes of each conveying roller 32. A plurality of conveying motors 34 are fixedly installed on the body 1. The conveying motors 34 are respectively adjacent to the two sides of the two ends of the track frame 31. The conveying motors 34 are respectively connected to the conveying rollers 32 on both sides of the two ends.

[0045] Furthermore, the difference from the above embodiment lies in that a material guide frame 35 is fixedly mounted on the machine body 1, the material guide frame 35 is adjacent to one end of the rail frame 31, the material guide frame 35 is opposite to the conveying roller 32 on one end of the rail frame 31, the width of the material guide frame 35 is the same as the spacing between the two sides of the conveying roller 32, a limit clamp 36 is provided on the material guide frame 35, a yoke 37 is provided on the limit clamp 36, and the yoke 37 is a steering shaft yoke.

[0046] Furthermore, the difference from the above-mentioned embodiment lies in that slots are provided on both sides of the limit clamp 36, and the slots of the limit clamp 36 are matched with the conveying roller 32, so that the conveying roller 32 utilizes the slots of the limit clamp 36 to drive the limit clamp 36 to move on the rail frame 31, and a raised slide is fixedly provided on the middle part of the rail frame 31, and the raised slide of the rail frame 31 is matched with the slot of the limit clamp 36, so that the limit clamp 36 is flipped 180 degrees in the middle part of the rail frame 31 through the mutual restriction of the raised slide and the slot.

[0047] Furthermore, the rail frame 31 is a half-stage spiral structure, that is, the track of one side of the rail frame 31 will lead to the other side of the rail frame 31 after passing through the middle part of the rail frame 31. At the same time, the relative surfaces of the two side tracks of the rail frame 31 are always kept inconvenient, so that when the limit clamp 36 moves in the middle part of the rail frame 31, one side of the limit clamp 36 rotates 180 degrees clockwise to the other side, and the other side of the limit clamp 36 rotates 180 degrees clockwise to one side, thereby allowing the limit clamp 36 to complete the flipping action.

[0048] Specifically, the length of the limit clamp 36 is relatively small. Currently, most limit clamps 36 with a length of about 5 cm are used. The limit clamp 36 will clamp and fix part of the position on the yoke 37. The short limit clamp 36 will not have a significant impact on the curvature of the middle part of the track frame 31, that is, the middle part of the track frame 31 has a larger curvature, and the limit clamp 36 can also move smoothly on the track frame 31. At the same time, this is the production line of the yoke 37. When the limit clamp 36 in the middle part of the track frame 31 has no power and cannot move actively, the subsequent yoke 37 on the production line will push the yoke 37 in front when the limit clamp 36 moves to this place, so that the yoke 37 in the middle part of the track frame 31 is pushed by the yoke 37 in front by the subsequent moving yoke 37 to complete the movement in the middle part of the track frame 31.

[0049] Furthermore, due to the size of the limit clamp 36, the conveying rollers 32 are arranged continuously and closely on the rail frame 31 to prevent the limit clamp 36 from falling off. In the figure, in order to maintain the clarity of the figure and avoid excessive crowding of the lines in the figure, the distribution of the conveying rollers 32 is relatively sparse.

[0050] When the yoke 37 is conveyed, the limit clamp 36 that clamps the fixed yoke 37 slides from the guide frame 35 to the rail frame 31, and the conveying roller 32 moves into the groove of the limit clamp 36, and the conveying motor 34 is started. The conveying motor 34 drives the toothed belt 33 to rotate, and the toothed belt 33 drives the conveying roller 32 to rotate, so that the conveying roller 32 drives the limit clamp 36 to move on the rail frame 31, and when the limit clamp 36 moves to the middle part of the rail frame 31, the track shape of the rail frame 31 limits the moving direction of the limit clamp 36, so that the limit clamp 36 is flipped 180 degrees as the limit clamp 36 moves, so that the limit clamp 36 drives the yoke 37 to turn over.

[0051] Furthermore, the difference from the above-mentioned embodiment lies in that a plurality of electrically-controlled telescopic rods 38 are fixedly mounted on the machine body 1, and the electrically-controlled telescopic rods 38 are all located directly below the rail frame 31; blocking plates 39 are fixedly mounted on the extension rods of the electrically-controlled telescopic rods 38, and the blocking plates 39 are all located directly below the processing head 28; a plurality of infrared detectors 310 are fixedly mounted on the machine body 1, and the infrared detectors 310 are all adjacent to the blocking plates 39; the infrared detectors 310 are used to detect the position of the yoke 37 on the rail frame 31, and the infrared detectors 310 are connected to the signals of the electrically-controlled telescopic rods 38.

[0052] Among them, when the limit clamp 36 moves to the infrared detector 310, the infrared detector 310 detects the position of the yoke 37 on the limit clamp 36, and the infrared detector 310 controls the operation of the electric telescopic rod 38, and the electric telescopic rod 38 drives the blocking plate 39 to move, so that the blocking plate 39 intercepts the limit clamp 36 on the rail frame 31 and no longer moves, so that the yoke 37 on the limit clamp 36 can be processed.

[0053] Furthermore, the difference from the above embodiment lies in that a material discharge chute 311 is fixedly mounted on the machine body 1, and the material discharge chute 311 is adjacent to the other end of the rail frame 31, so that the yoke 37 moved away from the rail frame 31 falls onto the material discharge chute 311, and a temporary retention box 312 is fixedly mounted on one side of the material discharge chute 311, and the temporary retention box 312 is communicated with the material discharge chute 311, and a guide plate 313 is rotatably mounted on the material discharge chute 311, and the guide plate 313 is used to guide the yoke 37 into the temporary retention box 312, and a rotating arm cylinder 314 is fixedly mounted on the material discharge chute 311, and the rotating arm cylinder 314 is dynamically connected to the guide plate 313.

[0054] Furthermore, a detector is provided at the other end of the rail frame 31, and the detector is used to detect whether the yoke 37 is qualified after processing.

[0055] Among them, when the limit clamp 36 moves away from the rail frame 31, after being detected by the detector, the qualified yoke 37 falls into the unqualified material chute 311 and slides away directly. After the unqualified yoke 37 falls on the unqualified material chute 311, the arm cylinder 314 is started, and the arm cylinder 314 drives the guide plate 313 to rotate, so that the guide plate 313 faces the temporary retention box 312. The unqualified yoke 37 is restricted by the guide plate 313 and slides into the temporary retention box 312, and then the workers collect the unqualified yoke 37 into the unqualified product box 210.

[0056] Working principle:

[0057] The steering shaft yoke is placed on the limiting clamp 36, and the limiting clamp 36 carries the steering shaft yoke to move on the rail frame 31. When the limiting clamp 36 moves to the bottom of a processing head 28, the limiting clamp 36 stops moving, and the ball nut frame 26 is started. The ball nut frame 26 drives the processing head 28 to move, and the processing head 28 is started to rotate, so that the processing head 28 is pressed against the steering shaft yoke on the limiting clamp 36, so that the processing head 28 processes the steering shaft yoke, and then the limiting clamp 36 is continued to be moved on the rail frame 31, and the limiting clamp 36 is stopped. The clamping member 36 is flipped under the influence of the shape of the rail frame 31, so that the limit clamping member 36 drives the steering shaft yoke to flip 180 degrees, so that the steering shaft yoke is turned over and processed at the next station until the steering shaft yoke is removed from the rail frame 31 after the processing is completed, thereby replacing the transmission effect of the robot arm on the yoke, reducing the cost of using the processing equipment, and using the preset direction of the rail frame 31 to enable the yoke to complete the flipping and other actions at a fixed position, simplifying the cumbersome process brought by the program-controlled robot arm operation, and improving the working efficiency of the processing equipment;

[0058] When processing is performed, the stepper motor 23 is started, and the stepper motor 23 drives the screw rod 22 to rotate on the column 21, so that the screw rod 22 drives the ball nut frame 26 to move, and the ball nut frame 26 is connected to the slide plate 25 so that the slide plate 25 moves on the slide rail 24, thereby moving the ball nut frame 26, and the ball nut frame 26 drives the processing motor 27 to move, and the processing motor 27 drives the processing head 28 to move, and the processing motor 27 is started, and the processing motor 27 drives the processing head 28 to rotate, so that the processing head 28 performs processing work;

[0059] When the yoke 37 is conveyed, the limit clamp 36 clamping the fixed yoke 37 slides from the guide frame 35 to the rail frame 31, and the conveying roller 32 moves into the notch of the limit clamp 36, and the conveying motor 34 is started. The conveying motor 34 drives the toothed belt 33 to rotate, and the toothed belt 33 drives the conveying roller 32 to rotate, so that the conveying roller 32 drives the limit clamp 36 to move on the rail frame 31, and when the limit clamp 36 moves to the middle part of the rail frame 31, the track shape of the rail frame 31 limits the moving direction of the limit clamp 36, so that the limit clamp 36 is turned over 180 degrees with the movement of the limit clamp 36, so that the limit clamp 36 drives the yoke 37 to turn over;

[0060] When the limit clamp 36 moves to the infrared detector 310, the infrared detector 310 detects the position of the yoke 37 on the limit clamp 36, and the infrared detector 310 controls the electric control telescopic rod 38 to operate, and the electric control telescopic rod 38 drives the blocking plate 39 to move, so that the blocking plate 39 intercepts the limit clamp 36 on the rail frame 31 and does not move, so that the yoke 37 on the limit clamp 36 can be processed;

[0061] When the limit clamp 36 moves away from the rail frame 31, after being detected by the detector, the qualified yoke 37 falls into the unqualified material chute 311 and slides away directly. After the unqualified yoke 37 falls on the unqualified material chute 311, the arm cylinder 314 is started, and the arm cylinder 314 drives the guide plate 313 to rotate, so that the guide plate 313 faces the temporary retention box 312. The unqualified yoke 37 is restricted by the guide plate 313 and slides into the temporary retention box 312, and then the workers collect the unqualified yoke 37 into the unqualified product box 210.
