Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading equipment, in particular to an automatic loading and unloading truss for a lathe. Background Art

[0002] When using a CNC lathe to process short bars, if it is equipped with an automatic loading and unloading device, it can significantly improve work efficiency and reduce the labor intensity of workers. During use, the existing loading and unloading device needs to be equipped with a flipping device to flip the workpiece to be processed so that the processing device can complete the processing of both sides of the workpiece. The entire processing process needs to go through several separate horizontal, vertical and flipping processes, which takes a long time and is more complicated. When there is a problem with the flipping device in the CNC machine tool, it will cause the entire device to be paralyzed, thereby affecting the processing process of the workpiece. Utility Model Content

[0003] The purpose of the utility model is to provide a lathe automatic loading and unloading truss to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An automatic loading and unloading truss for a lathe comprises: a lifting frame mounted on a truss body, the lifting frame being provided with a storage plate, a driving rod being rotatably mounted on the storage plate, a mounting plate being fixedly mounted on one end of the driving rod away from the storage plate, and a tensioning structure being further provided on the driving rod;

[0006] A clamping assembly, arranged on the mounting plate, comprising a deflection structure, wherein the deflection structure can drive two groups of clamping members symmetrically mounted on the mounting plate to move away from or toward each other, and when the two groups of clamping members are close to each other, the tensioning structure drives the two groups of clamping members to stably clamp the workpiece;

[0007] The reversal structure is arranged on the truss body and cooperates with the driving rod. When the lifting frame slides relative to the truss body, the reversal structure can drive the driving rod to rotate relative to the storage plate, and when the driving rod rotates, the tightening structure will enhance the clamping force of the clamping member on the workpiece.

[0008] The automatic loading and unloading truss of the lathe as described above: the clamping part includes a clamping plate rotatably mounted on the mounting plate, and the clamping plates are symmetrically arranged in two groups along the length direction of the mounting plate, and each group of the clamping plates is provided with a fixed block, and the fixed blocks are provided with a slide groove.

[0009] The automatic loading and unloading truss of the lathe as described above: the deflection structure includes a cylinder fixedly mounted on the mounting plate, and the cylinders are symmetrically arranged in two groups along the length direction of the mounting plate, and the telescopic ends of the two groups of cylinders are respectively fixedly connected to the sliding rods arranged in the sliding groove.

[0010] The automatic loading and unloading truss of the lathe as described above: the tensioning structure includes a movable sleeve mounted on the driving rod, the movable sleeve is slidably connected to the guide rod fixedly arranged on the storage plate, and a protrusion is formed on the inner wall of the movable sleeve, and the protrusion is slidably arranged in the engaging groove body opened on the driving rod.

[0011] The automatic loading and unloading truss for the lathe as described above: the engaging groove body comprises a corrugated groove opened on the driving rod, and the corrugated groove is provided in two groups along the circumferential direction of the driving rod.

[0012] The automatic loading and unloading truss of the lathe as described above: the tensioning structure also includes a spring slidably arranged on the driving rod, one end of the spring abuts against the movable sleeve, and the other end abuts against the lifting sleeve sleeve mounted on the driving rod, and the lifting sleeve is provided with two groups of articulated rods equidistantly arranged along its circumferential direction, and the end of the articulated rod away from the lifting sleeve is hinged to the clamping plate.

[0013] The automatic loading and unloading truss for the lathe as described above: the reversing structure includes a gear coaxially fixedly connected to the driving rod, and the gear cooperates with a toothed plate fixedly arranged on the truss body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting a clamping assembly and a tightening structure, the clamping plate can be driven to clamp the workpiece by utilizing the cooperation between the cylinder and the spring. During clamping, the clamping force of the clamping plate on the workpiece is provided by the spring. This clamping method can reduce the damage of the inner wall of the clamping plate to the outer wall of the workpiece, thereby improving the overall precision of the workpiece.

[0016] At the same time, by setting a reversing structure, the lifting frame can directly drive the workpiece to rotate when sliding in the length direction relative to the truss body, so as to facilitate the two sets of processing components under the truss body to process both sides of the workpiece, and during the rotation of the workpiece, the movable sleeve of the tensioning structure arranged on the driving rod will descend along the axial direction of the driving rod with the cooperation of the engaging groove body to further squeeze the spring, and then under the connection of the lifting sleeve and the hinged rod, the clamping force of the clamping plate on the workpiece will be increased, thereby preventing the workpiece from slipping from the front of the clamping plate; and during the rotation process, due to the cooperation between the protrusion and the corrugated groove, the rotation angle of the workpiece will be stabilized at one hundred and eighty degrees, thereby effectively preventing the workpiece from rotating excessively or insufficiently, so that the subsequent processing device can normally cooperate with the workpiece to be processed to complete the processing of the workpiece.

[0027] For details, please refer to Figure 1 , Figure 2 The truss body 1 is provided with a control mechanism 2, which can drive the lifting frame 3 to lift in the vertical direction of the space, drive the storage plate 4 to deflect relative to the lifting frame 3, and drive the lifting frame 3 to slide in the length direction of the truss body 1. Specifically, a workpiece to be processed is placed under the truss body 1. During actual operation, the driving rod 12 will first remain parallel to the ground, and the lifting frame 3 is located at the center of the truss body 1. When the control mechanism 2 is working, it will first cause the lifting frame 3 to descend and approach the workpiece to be processed, and then drive the clamping assembly arranged on the mounting plate 14 to clamp the workpiece. After the workpiece is clamped stably, the control mechanism 2 will drive the clamped workpiece to be processed to rise and approach the truss body 1, and the lifting frame 3 will rise. When it reaches the highest position, the control mechanism 2 will drive the storage plate 4 and the driving rod 12 to rotate 90 degrees, so that the driving rod 12 remains parallel to the ground, and then the lifting frame 3 slides along the truss body 1 again, so that the lifting frame 3 moves to the top of the processing device (not shown in the figure) placed under the truss body 1, and then the lifting frame 3 will descend under the drive of the control mechanism 2 until the workpiece to be processed is located on the processing station. The processing device will cooperate with the clamping assembly to receive the workpiece to be processed, and then the device will process one side of the workpiece. After one side is processed, the control mechanism 2 will drive the lifting frame 3 to move again, and transfer the workpiece on one side that has been processed to the processing device on the other side to perform processing on the other side.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4, a clamping assembly, arranged on the mounting plate 14, comprising a deflection structure, the deflection structure can drive two groups of clamping members symmetrically mounted on the mounting plate 14 to move away from or approach each other, and when the two groups of clamping members approach each other, the tensioning structure will drive the two groups of clamping members to stably clamp the workpiece;

[0031] Preferably, see Figure 1 , Figure 2 , Figure 3 , Figure 4 The two groups of cylinders 15 are synchronously controlled by the control mechanism 2. In the initial state, the telescopic ends of the two groups of cylinders 15 are close to the mounting plate 14. At this time, the slide rod 1501 is located at the end of the travel of the slide groove 1601 away from the clamping plate 11, and the two groups of clamping plates 11 are away from each other. When the lifting frame 3 drives the driving rod 12 and the mounting plate 14 parallel to the ground to approach the workpiece to be processed, so that the clamping plate 11 and the workpiece are in the same horizontal plane, the control mechanism 2 will drive the cylinder 15 to move, pushing the two groups of clamping plates 11 to move closer to each other, until the clamping plate 11 contacts the outer wall of the circular workpiece, and the cylinder 15 stops. Working, at this time, the two groups of clamping plates 11 will be further approached to each other with the cooperation of the tensioning structure, so as to stably clamp the workpiece, and then the control mechanism 2 will drive the storage plate 4 and the workpiece with the clamping assembly to flip over, until the storage plate 4 is perpendicular to the ground, the control mechanism 2 will drive the workpiece to move, until one side of the workpiece is processed by the processing device on the left, the control mechanism 2 will drive the workpiece on the processed side to move to the processing device on the right, and during the movement, the reversal structure set on the truss body 1 will drive the workpiece to flip over so that the other side of the workpiece can be processed later.

[0033] For details, please refer to Figure 1 , Figure 2 , Figure 3 The movable sleeve 7 is provided with two sets of sleeve tubes 701 equidistantly along its circumferential direction. The sleeve tubes 701 are slidably connected to the guide rod 10 fixedly arranged on the mounting plate 14. Under the cooperation between the guide rod 10 and the sleeve tubes 701, the movable sleeve 7 can only slide along the axial direction of the guide rod 10.

[0034] The engaging groove body includes a wave-shaped groove 1202 formed on the driving rod 12, and two groups of the wave-shaped groove 1202 are arranged along the circumferential direction of the driving rod 12;

[0035] Preferably, see Figure 4 The above-mentioned corrugated grooves 1202 are provided with two groups around the circumferential direction of the driving rod 12 , the connection point of the two groups of corrugated grooves 1202 is a wave valley 1203 , and the highest point of each group of corrugated grooves 1202 is a wave crest 1201 .

[0036] The tightening structure further comprises a spring 8 slidably arranged on the driving rod 12, one end of the spring 8 abuts against the movable sleeve 7, and the other end abuts against the lifting sleeve 9 sleeved on the driving rod 12, and the lifting sleeve 9 is equidistantly arranged with two sets of hinged rods 13 along its circumferential direction, and one end of the hinged rod 13 away from the lifting sleeve 9 is hinged to the clamping plate 11;

[0037] In combination with the above, in the initial state, the protrusion 702 is combined with the crest 1201 of one group of corrugated grooves 1202, and the spring 8 is always in a compressed state. At this time, the compressed spring 8 will push the lifting sleeve 9 to move closer to the mounting plate 14, and then under the connection action of the fixed-length hinged rod 13, when the clamping plate 11 contacts the outer wall of the workpiece, under the action of the spring 8, the two groups of clamping plates 11 will continue to approach each other, thereby clamping the workpiece. At this time, the clamping force of the clamping plate 11 on the workpiece is provided by the spring 8. This clamping method will reduce the damage of the inner wall of the clamping plate 11 to the outer wall of the workpiece, thereby improving the overall precision of the workpiece.

[0038] For further information, see Figure 1-Figure 5 , a lathe automatic loading and unloading truss, further comprising a reversing structure, the reversing structure being arranged on the truss body 1 and cooperating with the driving rod 12, when the lifting frame 3 slides relative to the truss body 1, the reversing structure can drive the driving rod 12 to rotate relative to the storage plate 4, and when the driving rod 12 rotates, the tightening structure will enhance the clamping force of the clamping member on the workpiece;

[0039] The reversing structure includes a gear 6 coaxially fixedly connected to the driving rod 12, and the gear 6 cooperates with a toothed plate 5 fixedly arranged on the truss body 1;

[0040] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 In combination with the above, when one side of the workpiece is processed, the control mechanism 2 drives the lifting frame 3 to drive the workpiece on the processed side to the processing device on the other side of the truss body 1 for processing. During the process, the gear 6 on the driving rod 12 will be combined with the toothed plate 5. With the continuous movement of the lifting frame 3, the gear 6 will drive the driving rod 12, the mounting plate 14 and the clamped workpiece to rotate until the gear 6 is separated from the toothed plate 5. The gear 6 will drive the driving rod 12 and the workpiece to rotate 180 degrees, thereby facilitating the subsequent processing device to process the other side of the workpiece;

[0041] In particular, during the rotation of the gear 6, the protrusion 702 will be squeezed with the groove wall of the corrugated groove 1202, thereby forcing the movable sleeve 7 to descend along the axial direction of the driving rod 12 to further squeeze the spring 8. At this time, the squeezed spring 8 will push the lifting sleeve 9 to continue to move toward the mounting plate 14, so that the clamping force of the clamping plate 11 on the workpiece is increased during the rotation, thereby preventing the workpiece from slipping from the front of the clamping plate 11; and during the rotation of the gear 6 and the tooth plate 5, due to the cooperation between the protrusion 702 and the corrugated groove 1202, the gear 6 will drive the driving rod 12 and the workpiece to rotate at a stable angle of one hundred and eighty degrees, thereby effectively preventing the workpiece from rotating excessively or insufficiently, so that the subsequent processing device can normally cooperate with the workpiece to be processed to complete the processing of the workpiece.
