Description

Technical Field

[0001] The invention relates to the technical field of conveying and feeding, in particular to automatic conveying and feeding equipment for a full-automatic straightening machine. Background Art

[0002] Bars and shaft parts (hereinafter collectively referred to as "workpieces") will inevitably bend and deform during rolling, forging, heat treatment or machining. Straightening is a key process to ensure the straightness, roundness and other form and position tolerances of the workpiece to meet the requirements of subsequent processing or assembly. The straightening machine is the core equipment to realize this process. It mainly clamps the end of the workpiece through the centering of the center and drives the workpiece to rotate, so that the straightening machine can detect the bent part of the workpiece, and then apply external force to make the workpiece produce reverse plastic deformation to offset the original bending. The straightening processing efficiency and accuracy of the straightening machine directly affect the product quality and production cost.

[0003] The existing workpiece loading method of the straightening machine is mainly to load the workpiece through two conveyor plates that make a circular motion. There are multiple V-shaped grooves on the conveyor plates. The conveyor plates first move upward, so that the V-shaped grooves of the conveyor plates lift the corresponding workpieces on the material rack, and then the conveyor plates carry the workpieces and move toward the straightening machine. Then the conveyor plates move downward, so that the workpieces are separated from the V-shaped grooves of the conveyor plates and fall on the material rack again. Finally, the conveyor plates return to their initial position, thereby realizing intermittent rightward conveying of the workpieces.

[0004] However, the following problems exist when loading the workpiece: when the existing conveyor plate is conveying the workpiece, due to the bending deformation of the workpiece, the workpiece may be unevenly supported and skewed because one conveyor plate supports the bent part of the workpiece and the other conveyor plate supports the unbent part of the workpiece. When the skewed workpiece is loaded onto the straightening machine, it cannot be ensured that the workpiece and the straightening machine are centered, which makes it difficult for the top to accurately center and clamp the workpiece. At the same time, when the top clamps the workpiece, the workpiece may slide or flip and fall out of the straightening machine, requiring manual shutdown and re-placement of the workpiece. This not only reduces the straightening processing efficiency of the workpiece, but also affects the clamping stability due to clamping deviation caused by manual placement, thereby affecting the straightening effect of the workpiece.

[0028] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0029] See Figure 1 、 Figure 2 and Figure 3 A fully automatic straightening machine automatic conveying and loading equipment comprises a base 1, two groups of symmetrically arranged material racks 13, a straightening machine 2 is installed in the middle of the upper end of the base 1, a conveying unit 3 for intermittently conveying workpieces to the right is installed on the base 1, and a straightening unit 4 is installed on the conveying unit 3. Two clamping units 5 symmetrically arranged front and back are installed between the base 1 and the straightening machine 2, and a positioning group 11 is installed on the left side of the upper end of the base 1; the material rack group 13 comprises two symmetrically arranged material racks, and a plurality of V-shaped material troughs evenly arranged left and right are opened on the material rack, and the material rack is fixedly connected to the upper end of the base 1 through a connecting frame.

[0030] See Figure 1 、 Figure 2 and Figure 3 The conveying unit 3 includes two conveying plates 31 arranged in front and behind and moving along a circular trajectory. A driving member 32 is connected between the lower side of the conveying plate 31 and the base 1. The circular movement of the conveying plate 31 is realized by the driving member 32. A plurality of V-shaped grooves evenly arranged left and right are opened on the conveying plate 31. When the conveying plate 31 is in the initial position, the V-shaped grooves and the V-shaped material troughs correspond one to one.

[0031] See Figure 1 、 Figure 2 and Figure 3 It should be noted that the straightening machine 2 adopts the existing technology, which includes a top clamping part 21, a gantry 22, a detection and straightening part 23 and an elastic support part 24. The top clamping part 21 is symmetrically arranged front and back and is used to center and clamp the workpiece and drive the workpiece to rotate. The detection and straightening part 23 is used to detect the bent part of the workpiece and straighten the workpiece. The elastic support part 24 is used to provide elastic support for the lower side of the workpiece.

[0032] See Figure 4 It should be noted that the driving member 32 in the present invention adopts the existing technology, including a hydraulic cylinder assembly 321, an electric slider assembly 322 and a mounting plate 323. The hydraulic cylinder assembly 321 is used to drive the conveying plate 31 to move up and down through the electric slider assembly 322 and the mounting plate 323. The electric slider assembly 322 drives the conveying plate 31 to move left and right through the mounting plate 323. The conveying plate 31 is driven to move along a circular trajectory by controlling the hydraulic cylinder assembly 321 and the electric slider assembly 322.

[0033] The present invention is used for automatic loading of workpieces. The present invention can straighten (position calibrate) shaft-type workpieces to prevent them from being skewed, and ensure that the axis of the workpiece and the axis of the top in the top clamping part 21 are completely collinear in the front-to-back direction; when the workpiece is transported to the corresponding position of the top clamping part 21, the present invention can also center and clamp the end of the workpiece, thereby ensuring that the top clamping part 21 accurately centers and clamps the workpiece, ensuring the straightening accuracy of the workpiece, and at the same time, the present invention can also center the shaft-type workpiece, thereby preventing the workpiece from separating from the elastic support part 24, thereby ensuring the processing quality of the workpiece.

[0034] See Figures 1 to 4 Specifically, the workpiece is placed in the leftmost V-shaped trough of the left material rack, and then the driving member 32 is started to drive the conveying plate 31 to make a circular motion. The conveying plate 31 first moves upward so that the V-shaped groove of the conveying plate 31 can lift the workpiece in the corresponding V-shaped trough, and then the conveying plate 31 drives the workpiece to move to the right for a distance, and the conveying plate 31 drives the workpiece to move to the right to the next corresponding V-shaped trough, and then the conveying plate 31 drives the workpiece downward. When the workpiece moves to the corresponding V-shaped trough, the workpiece moves out of the V-shaped groove and falls into the V-shaped trough, and finally the conveying plate 31 moves to the left to the initial position, so that the conveying plate 31 drives the workpiece to move intermittently to the right, so that the conveying plate 31 loads the workpieces one by one to the elastic support part 24, and the subsequent straightening machine 2 can perform straightening processing on the workpiece.

[0035] When the conveying plate 31 drives the workpiece to move upward, under the action of the alignment group 11, the workpiece is arranged in the center front and back. When the V-shaped groove on the conveying plate 31 located on the left side of the elastic support part 24 drives the workpiece to move to the right, the straightening unit 4 can straighten the workpiece front and back. Then, when the conveying plate 31 drives the workpiece to move to the elastic support part 24, the workpiece is in a non-deflected state. When the workpiece is loaded onto the elastic support part 24, the clamping unit 5 is controlled to center and clamp the end of the workpiece to ensure that the top clamping part 21 clamps the workpiece in a centering manner. When the workpiece straightening processing is completed, the conveying plate 31 can convey the workpiece on the elastic support part 24 to the right to the V-shaped material groove on the leftmost side of the right material rack group 13, completing the intermittent rightward movement of the workpiece after the straightening processing is completed, and then realizing continuous straightening processing of the workpiece.

[0036] See Figure 1 、 Figure 2 and Figure 3 The alignment group 11 includes two L-shaped plates 111 symmetrically arranged front to back and slidingly installed on the base 1. The L-shaped plate 111 is located on the left side of the top clamping part 21, and the conveying unit 3 is located between the two L-shaped plates 111. A top extension spring 112 is connected between the L-shaped plate 111 and the base 1. Alignment plates 113 are fixedly installed on the opposite sides of the horizontal sections of the two L-shaped plates 111, and the lower parts of the opposite sides of the two alignment plates 113 are provided with inclined surfaces.

[0037] The alignment group 11 is used to arrange the workpiece in the center front and back; specifically, when the conveying plate 31 drives the workpiece to move upward, the end of the workpiece can contact the corresponding inclined surface of the alignment plate 113, and cooperate with the inclined surface to move the alignment plate 113 in the direction of moving away from each other, and the alignment plate 113 compresses the corresponding extension spring 112 through the L-shaped plate 111. At the same time, the two alignment plates 113 elastically squeeze the workpiece in the direction of approaching each other under the action of the corresponding extension spring 112, ensuring that the workpiece and the base 1 are arranged in the center front and back. When the conveying plate 31 conveys the workpiece to the elastic support part 24 and the top clamping part 21 performs centering clamping on the workpiece, since the workpiece and the base 1 and the gantry 22 are arranged in the center front and back at this time, that is, the distance between the two ends of the workpiece and the corresponding top clamping part 21 is equal, the top clamping part 21 will not push the workpiece back and forth when performing centering clamping, which can prevent the workpiece from separating from the elastic support part 24.

[0038] See Figure 1 、 Figure 3 and Figure 4 The straightening unit 4 includes a tightening group 41 symmetrically installed on the front and rear sides of the conveying plate 31. The installation position of the tightening group 41 corresponds to the position of the V-shaped groove closest to the left side of the straightening machine 2. Two straightening plates 42 symmetrically arranged on the left and right are installed on the tightening group 41. A matching group 12 is installed on the base 1. When the conveying plate 31 drives the workpiece to move to the right, the matching group 12 and the tightening group 41 cooperate to drive the straightening plate 42 to straighten the workpiece back and forth.

[0039] The straightening unit 4 is used to straighten the workpiece back and forth; specifically, when the conveying plate 31 moves upward, the conveying plate 31 drives the straightening plate 42 to move upward through the clamping group 41, and when the straightening plate 42 moves to the position of the workpiece, the clamping group 41 drives the two corresponding straightening plates 42 to elastically clamp on the left and right sides of the workpiece, and then the conveying plate 31 drives the workpiece upward again, and when the conveying plate 31 drives the workpiece to move to the right, the matching group 12 and the clamping group 41 cooperate to drive the straightening plate 42 to straighten the workpiece back and forth, and when the conveying plate 31 conveys the workpiece to the elastic support part 24, the end of the workpiece remains in a state of being aligned with the top clamping part 21 (that is, a non-deflected state). At this time, the axis of the workpiece and the axis of the top in the top clamping part 21 are completely collinear in the front and rear directions, ensuring that the top clamping part 21 can accurately center and clamp the workpiece, thereby ensuring the straightening processing accuracy of the workpiece.

[0040] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5The tightening group 41 includes two elastic reset rods 411 arranged left and right and fixedly mounted on the conveying plate 31, and a sliding plate 412 is slidably mounted on the two elastic reset rods 411. The sliding plate 412 is initially set in contact with the conveying plate 31. The upper side of the sliding plate 412 and its corresponding two straightening plates 42 are slidably connected left and right. A tightening spring 413 is connected between the straightening plate 42 and the sliding plate 412. The upper ends of the opposite sides of the left and right straightening plates 42 are set as inclined surfaces, and the lower ends of the opposite sides of the left and right straightening plates 42 are movably mounted with multiple balls 421.

[0041] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The lower end of the sliding plate 412 is fixedly installed with a matching column block 414; the matching group 12 includes a matching plate 121 distributed under the conveying plate 31, and the left side of the matching plate 121 is set as a trapezoidal structure, and the inclined surface of the matching plate 121 is in contact with the corresponding matching column block 414. The lower side of the matching plate 121 is connected to the base 1 through two connecting plates 122 arranged symmetrically in front and back, and the connecting plate 122 is set as an elastic telescopic structure, the telescopic section of the connecting plate 122 is fixedly connected to the lower end of the matching plate 121, and the fixed section is fixedly connected to the upper end of the base 1; the matching plate 121 is located between the electric slider assembly 322 and the mounting plate 323, and the matching plate 121 and the electric slider assembly 322 are in contact.

[0042] The tightening group 41 is used to drive the straightening plate 42 to elastically clamp the workpiece, and the matching group 12 is used to cooperate with the tightening group 41 to drive the straightening plate 42 to straighten the workpiece back and forth; specifically, when the conveying plate 31 moves upward, the conveying plate 31 finally drives the straightening plate 42 to move upward through the elastic reset rod 411 sliding plate 412. When the straightening plate 42 moves upward and contacts the workpiece and continues to move upward, the workpiece will cooperate with the inclined surfaces of the left and right straightening plates 42 to push the two straightening plates 42 to move away from each other, and the two straightening plates 42 will be elastically clamped on the left and right sides of the workpiece under the elastic force of the tightening spring 413.

[0043] When the conveying plate 31 drives the workpiece to move to the right, the conveying plate 31 drives the sliding plate 412 to move to the right through the elastic reset rod 411, and the sliding plate 412 drives the matching column block 414 to move to the right. When the matching column block 414 contacts the inclined surface of the matching plate 121 and continues to move to the right, the two matching column blocks 414 will move away from each other, and the matching column blocks 414 will drive the corresponding sliding plates 412 to move away from each other. The sliding plates 412 move along the elastic reset rod 411 and cause the elastic reset rod 411 to generate a rebound force, and the sliding plates 412 drive The straightening plate 42 moves along the workpiece in the front-to-back direction to straighten the workpiece. The ball 421 can reduce the friction between the straightening plate 42 and the workpiece, so that the straightening plate 42 can move smoothly along the workpiece. When the conveying plate 31 conveys the workpiece to the elastic support part 24, the end of the workpiece remains aligned with the top clamping part 21 (i.e., non-deflected state), ensuring that the top clamping part 21 can accurately center and clamp the workpiece; under the action of the connecting plate 122 with an elastic telescopic structure, the matching plate 121 can move up and down synchronously with the conveying plate 31.

[0044] When the conveying plate 31 moves to the left to the initial position, the conveying plate 31 drives the sliding plate 412 to move to the left to the initial position through the elastic reset rod 411, and the sliding plate 412 drives the matching column block 414 to move to the left to the initial position. At the same time, the sliding plates 412 move towards each other to the initial position under the action of the elastic reset rod 411.

[0045] See Figure 1 and Figure 2 The clamping unit 5 includes a support assembly 51 mounted on the base 1 and an active member 52 mounted on the straightening machine 2. The active member 52 is mounted with a curved clamping plate 53. The active member 52 drives the curved clamping plate 53 and the support assembly 51 to clamp the workpiece end. The active member 52 also drives the curved clamping plate 53 to move back and forth, ensuring that the workpiece and the curved clamping plate 53 are centered and aligned. The rack assembly 13 is located between the front and rear support assemblies 51, and the clamping unit 5 is located between the symmetrical center clamping portions 21.

[0046] See Figures 1 to 4 The clamping unit 5 is used to clamp the end of the workpiece; specifically, when the conveying plate 31 conveys the workpiece to the elastic support part 24, the support group 51 can support the lower side of the workpiece, and then start the active member 52 to drive the arc clamping plate 53 to move downward, and the arc clamping plate 53 and the support group 51 cooperate to clamp the end of the workpiece, and the active member 52 can also drive the arc clamping plate 53 to move back and forth left and right, ensuring that the workpiece and the arc clamping plate 53 are centered and aligned, further ensuring that the top clamping part 21 accurately centers and clamps the workpiece, thereby improving the straightening accuracy of the workpiece.

[0047] See Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The support group 51 includes an adjustment plate 511 arranged above the base 1. The left side of the adjustment plate 511 is connected to the base 1 for sliding up and down through a guide rod 512 (the guide rod 512 is fixedly connected to the base 1, and the guide rod 512 is connected to the adjustment plate 511 for sliding). The right side of the adjustment plate 511 is threadedly connected to an adjusting screw 513, and the adjusting screw 513 is rotatably connected to the base 1. An arc-shaped support plate 515 is installed on the upper side of the adjustment plate 511 through multiple elastic support rods 514. A plurality of ball second 531 is installed on the inner arc surface of the arc clamping plate 53, and a plurality of ball third 516 is installed on the inner arc surface of the arc support plate 515. Among them, the elastic support rod 514 is provided with a large elastic force. When the workpiece is placed on the arc support plate 515, the arc support plate 515 will not compress the elastic support rod 514 under the action of the gravity of the workpiece.

[0048] See Figure 1 、 Figure 2 and Figure 7 The active part 52 includes an electric push rod 521 fixedly mounted on the gantry 22, a transmission plate 522 fixedly mounted on the lower end of the electric push rod 521, a reciprocating plate 523 slidingly mounted on the lower side of the transmission plate 522, and the lower side of the reciprocating plate 523 is connected to the corresponding arc-shaped clamping plate 53 through a plurality of elastic clamping rods 524.

[0049] See Figure 7 Two fixed plates 525 arranged symmetrically in front and back are fixedly installed on the lower side of the transmission plate 522. A wavy groove is opened on the fixed plate 525. A square plate 532 is fixedly installed on the upper side of the arc-shaped clamping plate 53. Matching rods 533 are fixedly installed at both ends of the square plate 532, and the matching rods 533 are slidably installed in the corresponding wavy grooves.

[0050] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8When the workpiece is moved to the upper side of the workpiece and continues to move downward, the arc clamping plate 53 and the arc support plate 515 cooperate to clamp the workpiece under the action of the elastic clamping rod 524 and the elastic support rod 514, and the workpiece can be rotated under the action of the ball 2 531 and the ball 3 516.

[0051] As the elastic abutment rod 524 is compressed, the transmission plate 522 moves downward relative to the arc-shaped clamping plate 53 (the distance between the transmission plate 522 and the arc-shaped clamping plate 53 gradually decreases). The transmission plate 522 then drives the fixed plate 525 downward relative to the square plate 532, causing the wavy groove and the mating rod 533 to cooperate and drive the square plate 532 to reciprocate left and right. Furthermore, because the reciprocating plate 523 and the transmission plate 522 are slidably connected, the square plate 532 drives the arc-shaped clamping plate 53 to reciprocate left and right, thereby ensuring that the axis of the arc-shaped clamping plate 53, the axis of the arc-shaped support plate 515, the axis of the workpiece, and the axis of the center of the center clamping portion 21 are completely collinear in the front-to-back direction, thereby further ensuring that the center clamping portion 21 can center the workpiece. Under the action of the elastic abutment rod 524 and the elastic support rod 514, the workpiece clamped by the arc-shaped clamping plate 53 and the arc-shaped support plate 515 is located in the middle of the opposite side of the adjustment plate 511 and the transmission plate 522.

[0052] By screwing the adjusting screw 513, the adjusting plate 511 is driven to move up and down along the guide rod 512 to achieve height adjustment of the adjusting plate 511. Then, when straightening workpieces of different sizes, it is ensured that the workpieces centered and clamped by the arc clamping plate 53 and the arc support plate 515 can be aligned with the centering clamping position of the top clamping part 21, ensuring that the top clamping part 21 can perform centering clamping on workpieces of different sizes.

[0053] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
