Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figures 1-10 This invention provides a handling device for use with a cylindrical workpiece processing equipment, including a conveyor frame 100 and a clamping mechanism.

A pin 102 is connected to the output end of the cylinder 101. A connecting rod 103 is rotatably connected between the pin 102 and the rotating rods 104.

[0038] Referring to Figure 2 , one side of the two groups of clamping blocks 200 close to each other is designed in an arc shape, in the closing process of the clamping blocks 200 clamping the cylindrical materials, the approaching circular structure formed by the two arc shapes can realize automatic alignment of the center of the materials and the clamping blocks 200, and realize clamping and automatic positioning of the cylindrical materials.

[0039] Further, the inside wall of the clamping block 200 movably sleeved with a detection clamping block 203 close to the end region, a spring is arranged between the detection clamping block 203 and the clamping block 200, the clamping block 200 is further provided with a switch one 204 matched with the detection clamping block 203, one end of the detection clamping block 203 extending to the outside of the clamping block 200 is further provided with an inverted bevel matched with the clamped materials.

[0040] Further, the transmission rod 202 is designed to be symmetrically distributed in the horizontal direction on the side wall of the clamping block 200, and the two groups of transmission rods 202 are synchronously transmitted through a belt.

[0041] It should be noted that the outer side wall of the transmission rod 202 is provided with a flexible rubber layer for anti-skid and buffering, and the outer side of the transmission rod 202 is designed in a spiral.

[0042] It should be noted that the edge area of the driving groove 319 is provided with a one-way valve connected with the communication groove 305, and the flow direction of the one-way valve is towards the inside of the communication groove 305.

[0043] Further, the flow area of the first sealing cavity 301 is larger than that of the second sealing cavity 302, and the cross-sectional area of the first piston 304 is larger than that of the transition groove 306. It should be noted that when the displacement of the ball detection block 300 compresses the liquid in the first sealing cavity 301 or the displacement of the first piston 304 compresses the liquid in the driving groove 319, the stroke amplification of the secondary hydraulic transmission displacement, i.e. the displacement of the piston rod 303 or the fourth piston 312, can be realized through the different cross-sectional areas.

[0044] Referring to Figure 6 - Figure 10 The buffer assembly includes a fifth piston 314 arranged at both ends of the first piston 304. The two ends of the first piston 304 are provided with cylindrical grooves, and the fifth piston 314 is sleeved in the grooves. The fifth piston 314 and the first piston 304 are connected by a spring. The middle section of the communication groove 305 is provided with a communication hole 316, and the two ends of the first piston 304 are provided with communication pipes 315. When the ball detection block 300 is pressed by the normal material without defects, the first piston 304 is in the middle position in the driving groove 319, and the communication pipe 315 is in communication with the communication hole 316 at this time. The side of the communication groove 305 close to the ball detection block 300 is also provided with a reset hole 317. When the ball detection block 300 is not in contact with the material, the reset hole 317 is in communication with the fifth piston 314.

[0045] Further, the side wall of the transition groove 306 is provided with a buffer groove 318, and the buffer groove 318 is sleeved with a third piston 311. The third piston 311 and the buffer groove 318 are provided with a spring. The inside of the transition groove 306 is connected with a flow limiting block 320 through the spring. The flow limiting block 320 is in the form of a nail, and the smaller end of the flow limiting block 320 is towards the communication area of the transition groove 306 and the first detection groove 307. When the instantaneous pressure increases, the flow limiting block 320 will move towards the first detection groove 307, and block the communication area of the transition groove 306 and the first detection groove 307 to limit the flow, thereby reducing the unit time flow of hydraulic oil from the transition groove 306 to the first detection groove 307.

[0046] It should be noted that the detection mechanism is provided with multiple groups, and the second detection groove 308 is provided with one group. The first detection grooves 307 of each group of detection mechanisms converge to the second detection groove 308 through the same group of pipelines.

[0047] The working process of the carrying device for matching the cylindrical workpiece processing equipment is as follows:

[0048] Referring to the drawings Figure 1 The conveying frame 100 is moved above the cylindrical workpiece material to be processed through the XYZ-axis motor connected with the conveying frame 100. During clamping and carrying, the output end of the air cylinder 101 is first lowered, the connecting rod 103 is driven by the pin rod 102 to push the two side rotating rods 104 and the clamping block 200 to open, the conveying frame 100 is lowered by the XYZ-axis motor, the air cylinder 101 is reset to drive the two clamping blocks 200 to reset and close, and the automatic clamping and automatic alignment of the axis of the cylindrical material are realized through the arc-shaped design of the side wall of the clamping block 200.

[0049] Further, the length of the clamping block 200 is greater than the length of the material. By starting the driving motor 201, the driving motor 201 drives the transmission rod 202 to rotate synchronously through the gear set designed in the clamping block 200. Through the thread design on the outer side wall of the transmission rod 202, the cylindrical material is rotated and moved along the axis line to the detection block 203 at the same time, until the material contacts the detection block 203. The detection block 203 is pushed to the inside of the clamping block 200 by the inclined angle of the detection block 203 to trigger the switch one 204, indicating that the end of the material moves to the area where the detection block 203 is located. Further, through the electrical connection of the switch one 204 and the driving motor 201, the driving motor 201 is controlled to continue to rotate for a fixed time or number of turns, so that the material moves the end to extend beyond the detection block 203 by the same distance, so as to realize that after the cylindrical material is captured and clamped, the material can be automatically positioned and aligned with the axis line, and the distance of the end of the material extending beyond the detection block 203 is constant when the material is moved, so that the position and posture of the clamped cylindrical material remain consistent, thereby facilitating automatic clamping and automatic positioning in the carrying, conveying and processing process, reducing the workload of machine and manual auxiliary adjustment, and improving the overall efficiency of cylindrical workpiece processing.

[0050] Further, in the process of rotating and moving the cylindrical material driven by the transmission rod 202, the surface defects and straightness of the material can be automatically detected by the ball detection block 300. The specific working process is as follows: after the two side clamping blocks 200 are closed to clamp the cylindrical rod, since the diameters of the cylindrical material are consistent, the material and the ball detection block 300 contact to generate the same force on the ball detection block 300. Under the support of the transmission rod 202, the material pushes the various ball detection blocks 300 to move the same distance. In the initial state of the ball detection block 300 not being affected by the external force of the material, the communication pipe 315 is in communication with the reset hole 317. At this time, the communication groove 305 is in communication with the inside of the driving groove 319, and the pressure in the communication groove 305 does not change, so the piston four 312 is not pushed. When the material contacts the ball detection block 300, the material with a standard diameter and a surface without defects pushes the ball detection block 300 towards the inside of the sealing cavity 301, and the distance makes the piston one 304 move to the middle of the driving groove 319. At this time, the communication pipe 315 is in communication with the communication hole 316, and the driving groove 319 and the communication groove 305 remain in communication, and the pressure in the communication groove 305 does not change.

[0051] When the transmission rod 202 drives the material to rotate through the ball detection block 300, if the surface of the material has defects, including defects, protrusions, etc., when the surface of the material has defects, the surface appears concave, the ball detection block 300 extends under the spring force in the sealed cavity 301, drives the piston rod 303 and the piston 304 to move a small distance towards the ball detection block 300, the piston 304 generates pressure on the inside of the driving groove 319 close to the side of the ball detection block 300, and the hydraulic oil inside the driving groove 319 close to the side of the ball detection block 300 is pumped into the communication groove 305 through the one-way valve, and in the process of moving the piston 304, the pressure inside the driving groove 319 away from the side of the ball detection block 300 is low, so that the piston 314 away from the side of the ball detection block 300 extends, fills the negative pressure on the side of the piston 304 with low pressure in the process of moving, and the oil pumped into the communication groove 305 further enters the transition groove 306, and further enters the detection groove 307, and drives the piston 312 to move. When the defect is large, the moving distance of the ball detection block 300, the piston 304 and the piston 312 will also increase, and when the defect reaches a certain degree, the piston 312 will be driven to move until the switch 313 is triggered, so as to indicate that the group of materials has defects. Through the electrical connection between the switch 313 and the XYZ axis motor and the cylinder 101, the XYZ axis motor is controlled to convey the group of materials to the above of the defective product recycling area, and the two clamping blocks 200 are opened by the lifting of the cylinder 101, and the material is put into the defective product recycling area. When the surface of the material has protrusion defects, the protrusion of the material drives the ball detection block 300 to move towards the clamping block 200, further drives the piston 304 to move away from the ball detection block 300, and the same, the pressure on the side of the piston 304 away from the ball detection block 300 increases, the internal hydraulic oil is pumped into the communication groove 305, and the piston 312 is driven to move, and the pressure on the side of the piston 304 close to the ball detection block 300 is small, which is compensated by the movement of the piston 314 close to the ball detection block 300, so as to realize the non-differential detection of the concave and convex defects on the surface of the material.

[0052] Further, the material rotates and advances during clamping in the clamping block 200. If the material lacks straightness, the difference in surface parameters compared to normal material is smaller than the defect. Therefore, during the movement of the piston four 312 driven by the ball detection block 300, the displacement amplitude of the piston four 312 is small, and even cannot trigger the switch three 313. However, during the movement of each group of piston four 312, the change amount can be collected in the detection groove two 308 in the form of hydraulic oil through the movement of the piston four 312, so as to realize the collection of the detection result. When the straightness is insufficient, the surface parameter defect parameter drives each group of piston four 312 to displace and collect the hydraulic oil, and drives the piston two 309 until the switch two 310 is triggered. Through the electrical connection between the switch two 310 and the XYZ axis motor and the cylinder 101, the XYZ axis motor is controlled to convey this group of materials to above the defective product recovery area, and the two clamping blocks 200 are opened through the lifting of the cylinder 101, so as to put the materials into the defective product recovery area, realize the collection and amplification detection of the overall straightness of the materials, and realize the recovery of the defective products.

[0053] It needs to be explained that when the material moves progressively inside the clamp block 200, the advancing end of the material is in contact with the ball detection block 300 which is not under pressure and exerts pressure on it. In this process, the material pushes the ball detection block 300 so that the piston one 304 moves from the initial position to the middle of the drive groove 319, and the communication pipe 315 moves from communication with the reset hole 317 to communication with the communication hole 316. The end of the material is constantly out of contact with the ball detection block 300. In this process, the piston one 304 moves from the middle of the drive groove 319 to the initial position, and the communication pipe 315 moves from communication with the communication hole 316 to communication with the reset hole 317. Specifically, the ball detection block 300 and the material are from no contact to contact and from contact to separation, which is close to a fault type change, and the change range is large, which causes the ball detection block 300 to be pushed sharply towards the inside of the clamp block 200 or makes the ball detection block 300 quickly reset after being out of pressure. The communication pipe 315 changes the communication between the communication hole 316 and the reset hole 317, the piston one 304 compresses the hydraulic oil in the communication groove 305 for a short time, the instantaneous pressure in the communication groove 305 changes greatly, the instantaneous pressure in the communication groove 305 and the transition groove 306 changes greatly, so that the oil does not meet the flow from the gap between the flow limiting block 320 and the transition groove 306 into the detection groove one 307. The oil with instantaneous change will push the flow limiting block 320 to move towards the detection groove one 307, but the nail-shaped structure of the flow limiting block 320 makes the small end of the diameter inserted into the flow area between the transition groove 306 and the detection groove one 307, which reduces the flow area between the transition groove 306 and the detection groove one 307, and reduces the total amount of hydraulic oil flowing into the detection groove one 307 per unit time. The instantaneous pressure change will be stored through the compression of the piston three 311 and the spring between the piston three 311 and the buffer groove 318, and after the piston one 304 resets quickly, the hydraulic oil will be back-pressed into the drive groove 319 through the communication pipe 315 to reset, so as to avoid triggering the piston four 312 when the ball detection block 300 is in contact with the material and out of contact with the material. It needs to be explained that when the material surface is detected, since the material has been preliminarily screened, this detection is aimed at the last synchronous detection before processing and carrying, which generally only appears in small amplitude bending or depression due to collision and stacking in the conveying process, and will not appear large fault type defects similar to the contact and separation of the material and the ball detection block 300. Therefore, when the ball detection block 300 contacts the defect area of the material, there is a defect from small to large buffer area first, and the change rate of the defect area is also much smaller than that when the ball detection block 300 is out of contact and in contact with the material. When the defect is passed, the pressure change in the drive groove 319 pumps the hydraulic oil in the communication groove 305 with a small and stable flow rate, the hydraulic oil can flow stably from the gap between the transition groove 306 and the flow limiting block 320, it is difficult to push the flow limiting block 320, so it is difficult to reduce the flow area, and therefore the piston four 312 can be driven stably.

[0054] It should be noted that the above switches are all pressure switch technology, which is triggered by hydraulic transmission pressure to deliver the material taken by the group to the defective product recycling area for rehandling and conveying a new group of materials.

[0055] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
