Description

Technical Field

[0001] This utility model relates to the field of robot processing technology, and in particular to a positioning fixture for robot arm processing. Background Technology

[0002] Robotic arms are a new type of device developed in the process of mechanized and automated production. In modern production, robotic arms are widely used in automated production lines. The research and development and production of robots has become a high-tech field. When performing production and processing, robotic arms need to clamp parts to facilitate processing such as drilling.

[0003] A robot machining fixture (CN221818392U) includes a base plate, with a U-shaped plate fixedly connected to the top of the base plate. This invention places a robot arm above a first arc-shaped clamping block. A starter motor drives a corresponding block to move via a screw. The block, through a connecting rod, moves a horizontal plate upwards. The horizontal plate, through a diagonal rod, moves a corresponding slider. The slider, through a rotating rod, moves a second arc-shaped clamping block, thereby clamping both sides of the robot arm. The horizontal plate moves the first arc-shaped clamping block upwards, allowing the first and third arc-shaped clamping blocks to also clamp the top and bottom of the robot arm. This multi-directional clamping of the robot arm eliminates the reliance on unidirectional clamping force, resulting in better stability and reduced wobbling during machining.

[0004] However, the aforementioned device cannot be freely adjusted to multiple angles during processing, which requires the installation of multiple sets of equipment during production. After processing one side, the equipment is moved to another set to continue processing, resulting in high production costs and low processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for robotic arm processing, which addresses the problem that existing devices cannot be freely adjusted to multiple angles during processing, resulting in the need to install multiple sets of equipment during production, with one set processing one side and then transferring to another set to continue processing, leading to high production costs and low processing efficiency.

[0006] To achieve the above objectives, this utility model provides a positioning fixture for robotic arm processing, including a worktable and an adjustment assembly. The adjustment assembly includes a clamping cylinder, a turntable, a support cylinder, a push rod, a drive motor, a vertical plate, and a first cylinder.

[0007] Two plates are slidably connected to the upright plate and the worktable, and are located at both ends of the worktable. The turntable is rotatably connected to the upright plate and is located on one side of the upright plate. The output end of the first cylinder is fixedly connected to the upright plate and the worktable, and is located at the top of the worktable. The output end of the drive motor is fixedly connected to the turntable and the upright plate, and is located on the outside of the upright plate. The clamping cylinder is fixedly connected to the turntable and is located on one side of the clamping cylinder. The supporting cylinder is located at the top of the worktable. The push rod is fixedly connected to the output end of the supporting cylinder and is located on one side of the supporting cylinder.

[0008] The adjustment assembly further includes a back plate and a collection box. The back plate is fixedly connected to the workbench and located on the top of the workbench. The collection box is detachably connected to the workbench and located on one side of the workbench.

[0009] The adjustment assembly further includes a support frame and a shelf. The support frame is fixedly connected to the workbench and located at the bottom of the workbench, and the shelf is fixedly connected to the support frame and located on one side of the support frame.

[0010] The adjustment assembly further includes a fixing bolt and a caster wheel. The caster wheel is rotatably connected to the support frame and is located on one side of the support frame. The fixing bolt is threadedly connected to the shelf and is located on one side of the shelf.

[0011] The adjustment assembly further includes a rubber head and a partition. The rubber head is fixedly connected to the top rod and located on one side of the top rod, and the partition is fixedly connected to the shelf and located on top of the shelf.

[0012] This utility model discloses a positioning fixture for robotic arm machining. When machining parts for the robotic arm, one end of the part is clamped by a clamping cylinder. The first cylinder controls the movement of the upright plate, so that the other end of the part is clamped by the clamping cylinder. During machining, the support cylinder drives the top rod to support the bottom of the part. After machining one side, the drive motor drives the turntable to rotate, thereby adjusting the machining angle of the part. This allows the device to machine multiple sides after a single clamping, reducing the number of clamping operations and improving work efficiency. It solves the problem that existing devices cannot freely adjust multiple angles during machining, resulting in the need to install multiple sets of equipment, with one set machining one side and then transferring to another set to continue machining, leading to high production costs and low processing efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1-2 , Figure 1 This is a structural diagram of a positioning fixture for robotic arm processing according to this utility model. Figure 2 This is a front view of a positioning fixture for robotic arm processing according to this utility model.

[0019] This utility model provides a positioning fixture for robotic arm processing, comprising a worktable 101 and an adjustment assembly 102. The adjustment assembly 102 includes a clamping cylinder 103, a turntable 104, a support cylinder 105, a push rod 106, a drive motor 107, a vertical plate 108, a first cylinder 109, a back plate 110, a collection box 111, a support frame 112, a storage plate 113, fixing bolts 114, casters 115, rubber heads 116, and a partition 117. This solution solves the problem that existing devices cannot freely adjust to multiple angles during processing, requiring multiple sets of equipment to be installed during production, with one set processing one side and then transferring to another set to continue processing, resulting in high production costs and low processing efficiency.

[0020] In this embodiment, two plates are slidably connected to the upright plate 108 and the worktable 101, and are located at both ends of the worktable 101. The turntable 104 is rotatably connected to the upright plate 108 and is located on one side of the upright plate 108. The output end of the first cylinder 109 is fixedly connected to the upright plate 108 and to the worktable 101, and is located at the top of the worktable 101. The output end of the drive motor 107 is fixedly connected to the turntable 104 and to the upright plate 108, and is located on the outside of the upright plate 108. The clamping cylinder 103 is fixedly connected to the turntable 104 and is located on one side of the clamping cylinder 103. The support cylinder 105 is disposed on the top of the worktable 101. The push rod 106 is fixedly connected to the output end of the support cylinder 105 and is located on the support... On one side of cylinder 105, when processing parts of the robot arm, one end of the part is clamped by clamping cylinder 103. The first cylinder 109 controls the movement of the upright plate 108 so that the other end of the part of the robot arm is clamped by clamping cylinder 103. During processing, the support cylinder 105 drives the top rod 106 to support the bottom of the part of the robot arm. After processing one side is completed, the drive motor 107 drives the turntable 104 to rotate, thereby adjusting the processing angle of the part of the robot arm. This allows the device to process multiple sides after one clamping, reducing the number of clamping operations and improving work efficiency. This solves the problem that existing devices cannot freely adjust multiple angles during processing, resulting in the need to install multiple sets of equipment, with one set processing one side and then transferring to another set to continue processing, leading to high production costs and low processing efficiency.

[0021] The adjustment assembly 102 further includes a back plate 110 and a collection box 111. The back plate 110 is fixedly connected to the workbench 101 and is located on the top of the workbench 101. The collection box 111 is detachably connected to the workbench 101 and is located on one side of the workbench 101. The back plate 110 is used to prevent processing debris from falling from the rear of the device. The collection box 111 is installed on the front of the device to collect processing debris.

[0022] Secondly, the adjustment assembly 102 also includes a support frame 112 and a shelf 113. The support frame 112 is fixedly connected to the workbench 101 and is located at the bottom of the workbench 101. The shelf 113 is fixedly connected to the support frame 112 and is located on one side of the support frame 112. The support frame 112 is used to support the device, and the shelf 113 is used to place uncollected items from the collection box 111 or items from the collection box 111 that have collected debris to be processed.

[0023] Furthermore, the adjustment assembly 102 also includes a fixing bolt 114 and a caster wheel 115. The caster wheel 115 is rotatably connected to the support frame 112 and is located on one side of the support frame 112. The fixing bolt 114 is threadedly connected to the shelf 113 and is located on one side of the shelf 113. The caster wheel 115 reduces the friction between the device and the placement surface, making it easier to move the device. The fixing bolt 114 fixes the device to the placement surface to prevent the caster wheel 115 from rotating during use and affecting processing.

[0024] Finally, the adjustment assembly 102 also includes a rubber head 116 and a partition 117. The rubber head 116 is fixedly connected to the top rod 106 and is located on one side of the top rod 106. The partition 117 is fixedly connected to the shelf 113 and is located on top of the shelf 113. The rubber head 116 prevents the high hardness of the top rod 106 from damaging the robot's parts. The partition 117 distinguishes the positions of the shelf 113, making it convenient to classify and place items.

[0025] In the positioning fixture for robotic arm processing according to this utility model, when processing parts of the robotic arm, one end of the part is clamped by the clamping cylinder 103. The first cylinder 109 controls the movement of the upright plate 108 so that the other end of the part of the robotic arm is clamped by the clamping cylinder 103. During the processing, the support cylinder 105 drives the top rod 106 to support the bottom of the part of the robotic arm. After processing one side is completed, the drive motor 107 drives the turntable 104 to rotate, thereby adjusting the processing angle of the part of the robotic arm. This allows the device to process multiple sides after one clamping, reducing the number of clamping operations and improving work efficiency. This solves the problem that existing devices cannot freely adjust multiple angles during processing, resulting in the need to install multiple sets of equipment, with one set processing one side and then transferring to another set to continue processing, leading to high production costs and low processing efficiency.

[0026] The above-disclosed embodiments are merely preferred embodiments of a positioning fixture for robotic arm processing according to the present invention. They should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes according to the claims of the present invention still fall within the scope of the present invention.
