Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a workpiece carrying device for a grinding robot. Background Technology

[0002] Currently, grinding robots mainly operate in two modes: one with a fixed workpiece, where a robotic arm holds the grinding tool and grinds the workpiece; and the other with a fixed grinding tool, where a robotic arm holds the workpiece and grinds it on the grinding tool. Of these two methods, the fixed-workpiece grinding mode has a wider range of applications, but because it requires tooling for fixation, it cannot grind the fixed portion of the workpiece. The fixed-tool grinding mode is limited by factors such as the size or material of the workpiece. For example, it may be limited by the space of the grinding robot's workstation, or the material may have low strength, making mechanical clamping difficult, thus hindering the use of the fixed-tool grinding mode. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects existing in the prior art and provide a workpiece carrying device for a grinding robot that can achieve full grinding of a workpiece by fixing the workpiece.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] The worktable can be flipped up and down.

[0007] A limiting cylinder is provided on the worktable, and a sliding hole for accommodating the workpiece is provided in the middle. The sliding hole passes through the upper and lower surfaces of the worktable, and the workpiece can slide up and down in the sliding hole.

[0008] Two support members are respectively disposed at both ends of the sliding hole, which can limit the workpiece in the sliding hole during the stationary and rotating processes of the worktable; the support members can slide along the axial direction of the sliding hole and can move closer to or further away from the sliding hole.

[0009] Furthermore, both ends of the worktable are fixed to a turntable, which drives it to rotate.

[0013] The rotating drum is disposed on the worktable, and its outer periphery is provided with gear teeth, which mesh with gears and are driven to rotate by the gears.

[0014] The workbench is formed by two plates fastening together. A T-shaped first receiving hole and a second receiving hole connected to the side of the first receiving hole are provided on the contact surface of the two plates. The rotating drum is disposed in the first receiving hole, and the gear teeth are disposed on the outer wall of the middle section protrusion. The gear is disposed in the second receiving hole and is driven to rotate by a third motor connected to the shaft.

[0015] Furthermore, the support component is displaced by a robotic arm.

[0016] Furthermore, the workbench is provided with a telescopic component, the telescopic component is provided with a connecting component, and the support component is provided on the connecting component and is rotatably connected to the connecting component.

[0017] Furthermore, the connector has a notch on the side near the limiting cylinder, the notch being located on the side of the connector away from the support; the support is provided with an L-shaped retaining plate, which can be inserted into the notch when the support is transferred to the axial position of the sliding hole.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0034] like Figures 1-3As shown, this embodiment provides a workpiece carrying device for a grinding robot, including a worktable 10, a limiting cylinder 20, and a support member 40. The worktable 10 can be rotated up and down. The limiting cylinder 20 is disposed on the worktable 10 and has a sliding hole in the middle for accommodating the workpiece. The sliding hole passes through the upper and lower surfaces of the worktable 10, and the workpiece can slide up and down in the sliding hole. There are two support members 40, which are respectively disposed at both ends of the sliding hole, and can limit the workpiece in the sliding hole during the worktable 10's stationary and rotating processes. The support members 40 can slide along the axial direction of the sliding hole and can move closer to or away from the sliding hole.

[0035] During operation, one of the support components 40 is located below the limiting cylinder 20. One end of the workpiece is supported on the support component 40, while the other end and more than half of the workpiece extend from above the limiting cylinder 20. The workpiece is then polished by a grinding tool carried by a robotic arm. The other support component 40 is located away from the limiting cylinder 20 to avoid causing obstruction.

[0036] After the workpiece is polished at one end, the support 40, which is far away, moves to the top of the workpiece and connects with it. Then, the worktable 10 is flipped to switch the positions of the upper and lower ends of the workpiece. The support 40, which is now below the workpiece, pushes the workpiece upward until more than half of the workpiece extends out from above the limiting cylinder 20. Then, the robotic arm carries the polishing tool to polish it.

[0037] The workpiece carrying device for the grinding robot provided in this embodiment limits the circumferential position of the workpiece by the limiting cylinder 20 and the axial position of the workpiece by the support member 40. The device can change the position of the upper and lower ends of the workpiece by flipping the worktable 10 and change its relative position with the limiting cylinder 20 by moving the support member 40. The workpiece can be fully exposed before and after flipping, thereby realizing all-round grinding of the workpiece.

[0038] In some embodiments, support frames 30 are provided at both ends of the workbench 10. A turntable 31 is provided on one side of the support frame 30, and a first motor 32 is provided on the other side. The first motor 32 passes through the main shaft of the support frame 30 and drives the turntable 31 to rotate. Fixed plates 11 are provided at both ends of the workbench 10. The workbench 10 is fixedly mounted on the turntable 31 through the fixed plates 11 and is rotated by the turntable 31.

[0039] Of course, in other embodiments, a turntable 31 can be provided at one end of the worktable 10, and a rotating shaft can be provided at the other end and inserted into a bearing seat. Or other methods that can achieve the flipping of the worktable 10 are not limited here.

[0040] In some embodiments, the worktable 10 is provided with a through hole, and the limiting cylinder 20 is inserted into the through hole. An assembly plate 22 is provided on the outer periphery of the limiting cylinder 20, and the limiting cylinder 20 is fixedly assembled to the outer ring of the through hole through the assembly plate 22. During use, different limiting cylinders 20 can be replaced as needed.

[0041] In some embodiments, a plurality of sliding grooves 21 are provided in the sliding hole, which extend axially along the sliding hole to limit the circumferential movement of the workpiece and prevent the workpiece from rotating within the limiting sleeve 20. Furthermore, rounded corners and / or chamfers can be provided at the edges of the sliding hole to facilitate workpiece insertion.

[0042] It is worth noting that, since the workpiece needs to be limited by the slide groove 21, the device has limitations on the shape of the workpiece and cannot be used for grinding cylindrical workpieces and spherical workpieces.

[0043] In some embodiments, the limiting cylinder 20 can rotate along its axis, thereby causing the workpiece to rotate, so as to reduce the range of movement of the robotic arm carrying the grinding tool, making it suitable for grinding operations in smaller spaces or on larger workpieces.

[0044] Specifically, this embodiment provides a specific structure for the rotation of the limiting cylinder 20: the limiting cylinder 20 is sleeved inside the rotating cylinder 50, and is driven to rotate by the rotating cylinder 50. More specifically, the rotating cylinder 50 is disposed on the worktable 10, and its outer periphery is provided with gear teeth 51, which mesh with gears 52, and are driven to rotate by gears 52. Of course, in other embodiments, the limiting cylinder 20 can also be driven to rotate by existing structures such as pulleys, and this is not limited here.

[0045] Preferably, to improve the cleanliness of the workbench 10, the workbench 10 can be formed by two plates fastening together. The mating surfaces of the two plates are provided with a T-shaped first receiving hole 101 and a second receiving hole 102 that communicates with the side of the first receiving hole 101. The rotating drum 50 is disposed in the first receiving hole 101, and the gear teeth 51 are disposed on the outer wall of the middle section protrusion. The gear 52 is disposed in the second receiving hole 102 and is driven to rotate by a third motor 53 connected to the shaft.

[0046] In some embodiments, the support member 40 is displaced by a robotic arm, or the workpiece is directly pushed or carried by the robotic arm. Furthermore, the robotic arm can also be configured to extend into the limiting cylinder 20 to expand its applicability. Of course, in other embodiments, other existing structures can also be used to achieve the displacement of the support member 40, and this is not limited here.

[0047] This embodiment provides a specific structure of a support member 40. A telescopic member is provided on the workbench 10, such as a cylinder 41. A connecting member 42 is provided on the telescopic rod of the cylinder 41. The support member 40 is provided on the connecting member 42 and is driven to rotate by a second motor 43 provided on the other side of the connecting member 42.

[0048] Preferably, the connector 42 has a notch 421 on the side near the limiting cylinder 20, and the notch 421 is located on the side of the connector 42 away from the support member 40; the support member 40 is provided with an L-shaped retaining plate 431, which can be inserted into the notch 421 when the support member 40 is transferred to the axial position of the sliding hole, so as to balance the force on the connector 42 and the support member 40.

[0049] Note: Unless otherwise specified, the fixed connection methods described in this article shall be existing fixed connection methods such as threaded connection, welding, and bonding.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
