Description

Technical Field

[0001] The utility model belongs to the technical field of robots, and particularly relates to a robot double - head fixture. Background Art

[0002] With the rapid development of industrial automation and intelligent manufacturing, robot technology is increasingly widely used in various fields. Especially in industries such as automobile manufacturing, machining, and electronic assembly, the requirements for robot fixtures are getting higher and higher. Not only do the fixtures need to have high precision and high stability, but they also need to be able to adapt to the clamping requirements of workpieces with various specifications and shapes to improve production efficiency and product quality.

[0003] Traditional robot fixtures are mostly single - head designs. Although they can meet basic clamping requirements, when it comes to multi - task processing, the fixtures need to be frequently replaced, which greatly reduces production efficiency and has poor flexibility. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a robot double - head fixture for the above - mentioned existing technical problems, which allows the robot to perform multi - task processing. When the first clamping fixture of the robot fails to do so, the inner - supporting fixture can be used for material taking, thus eliminating the need for replacement, and further improving the flexibility and production efficiency of the robot.

[0005] In view of this, the utility model provides a robot double - head fixture, which is characterized in that it includes: a mounting plate, three side ends of the mounting plate are respectively fixedly connected with a top plate and two fixing plates, a flange is fixedly installed on the top plate, a through - hole is provided in the middle position of the side of the flange away from the top plate, and a plurality of mounting holes are provided along the circumferential direction of the through - hole for connecting with the end of the robot arm. A clamping - jaw fixture mechanism and an inner - supporting fixture mechanism are respectively installed on the two fixing plates.

[0006] In this technical solution, the robot double - head fixture is firmly connected to the end of the robot through the mounting holes and the through - hole on the flange. When the robot receives a material - taking task, it first identifies the characteristics of the material to be taken (such as shape, size, material, etc.) through its control system, and then judges which fixture is more suitable accordingly. If the shape of the material is suitable for clamping and the clamping - jaw fixture mechanism is competent, the clamping - jaw fixture mechanism is preferentially selected for operation. Otherwise, the inner - supporting fixture mechanism is used. Thus, when one fixture of the robot is operating, the other fixture can be in a standby state, reducing the time for fixture replacement and positioning. The double - fixture can perform multiple operations on the same workpiece, thus significantly improving the production speed and efficiency.

[0007] In the above technical solution, further, the jaw-type fixture mechanism includes: an electric slide, the top of the electric slide is connected to a fixed plate, an electric slide rail is installed at the bottom of the electric slide, sliders are slidably connected to both ends of the electric slide rail, and two jaws are connected to the bottom ends of the two sliders.

[0008] In this technical solution, when the robot needs to use the jaw-type fixture to pick up materials, the control system will send commands to the electric slide and the electric slide rail. After receiving the commands, the electric slide rail starts to work, driving the sliders on it to slide to both sides or the center. As the sliders move, the jaws at their bottom ends will open or close accordingly. When the jaws close, they will firmly grip the materials; when the jaws open, the materials will be released.

[0009] In the above technical solution, further, the inner support-type fixture mechanism includes:

[0010] An electric push rod, the electric push rod is arranged on the upper surface of the fixed plate, and the output end of the electric push rod penetrates through the fixed plate and is connected with a pressing block;

[0011] A fixture cylinder, an extrusion part is slidably installed in the fixture cylinder, an inner support plate is connected to the outer end of the extrusion part, and the inner support plate is located outside the fixture cylinder;

[0012] Wherein, the pressing block is slidably connected with the extrusion part.

[0013] In this technical solution, when it is necessary to clamp a workpiece, the electric push rod extends, pushing the pressing block to move downward. At the same time, the pressing block presses the extrusion part, so that the pressurizing part slides outward in the fixture cylinder, driving the inner support plate to expand outward until the inner support plate is in close contact with the inner surface of the workpiece and applies sufficient clamping force, so as to pick up the materials.

[0014] In the above technical solution, further, three extrusion parts are arranged circumferentially.

[0015] In this technical solution, setting the extrusion parts to three and evenly distributing them circumferentially can ensure that the forces received by the inner support plate from the materials during the extrusion process are uniform and balanced, thereby improving the stability and reliability of material picking.

[0016] In the above technical solution, further, the pressing block is in the shape of a triangular prism, three first inclined chutes are arranged circumferentially on the pressing block, and a second inclined chute is arranged on the extrusion part.

[0017] In this technical solution, when it is necessary to unload the workpiece, the electric push rod contracts, driving the pressing block to move upward. Under the action of the first inclined chute and the second inclined chute, the three extrusion parts and the inner support plates connected to them are driven to move inward, so as to unload the workpiece.

[0018] In the above technical solution, further, a chute adapted to the pressing part is provided on the outer wall of the fixture cylinder.

[0019] In this technical solution, under the action of the chute, the pressing part moves stably inwards or outwards.

[0020] The beneficial effects of the present utility model are as follows: The robot double-head fixture is firmly connected to the arm end of the robot through the mounting holes and through holes on the flange. When the robot receives the material taking task, it first identifies the characteristics of the material to be taken (such as shape, size, material, etc.) through its control system, and judges which fixture is more suitable accordingly. If the shape of the material is suitable for clamping and the clamping fixture mechanism is competent, the jaw-type fixture mechanism is preferentially selected for operation. Otherwise, the inner support type fixture mechanism is used. Thus, when the robot is operating on one fixture, the other fixture can be in the standby state, reducing the time for changing the fixture and positioning. The double fixture can perform multiple operations on the same workpiece, thereby significantly improving the production speed and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:

[0035] As Figure 1-6 shown, this embodiment provides a robot double-head fixture, including: a mounting plate 1, three side ends of the mounting plate 1 are respectively fixedly connected with a top plate 2 and two fixing plates 3, a flange 4 is fixedly installed on the top plate 2, a through hole 7 is provided in the middle position of the side of the flange 4 away from the top plate 2, and a plurality of mounting holes 8 are provided along the circumference of the through hole 7 for connecting with the arm end of the robot. A jaw-type fixture mechanism 5 and an inner support-type fixture mechanism 6 are respectively installed on the two fixing plates 3. The robot double-head fixture is firmly connected to the arm end of the robot through the mounting holes 8 and the through hole 7 on the flange 4. When the robot receives a material taking task, it first identifies the characteristics of the material to be taken (such as shape, size, material, etc.) through its control system, and accordingly judges which fixture is more suitable. If the shape of the material is suitable for clamping and the clamping-type fixture mechanism can handle it, the jaw-type fixture mechanism 5 is preferably selected for operation. Otherwise, the inner support-type fixture mechanism 6 is used. Thus, when the robot is operating with one fixture, the other fixture can be in a standby state, reducing the time for changing the fixture and positioning. The double fixtures can perform multiple operations on the same workpiece, thereby significantly improving the production speed and efficiency.

[0036] Furthermore, the jaw-type fixture mechanism 5 includes: an electric slide 501, the top of the electric slide 501 is connected to the fixed plate 3, the bottom of the electric slide 501 is equipped with an electric slide rail 502, both ends of the electric slide rail 502 are slidably connected with sliders 503, and the bottoms of the two sliders 503 are connected with grippers 504. When the robot needs to use the jaw-type fixture to pick up materials, the control system will send instructions to the electric slide 501 and the electric slide rail 502. After receiving the instructions, the electric slide rail 502 starts to work, driving the sliders 503 on it to slide to both sides or the center. As the sliders 503 move, the grippers 504 at their bottoms will open or close accordingly. When the grippers 504 close, they will firmly grip the materials; when the grippers 504 open, the materials will be released.

[0037] Furthermore, the internal support-type fixture mechanism 6 includes: an electric push rod 601, the electric push rod 601 is arranged on the upper surface of the fixed plate 3, and the output end of the electric push rod 601 penetrates through the fixed plate 3 and is connected with a pressing block 603; a fixture cylinder 602, a pressing part 604 is slidably installed in the fixture cylinder 602, the outer end of the pressing part 604 is connected with an internal support plate 605, and the internal support plate 605 is located outside the fixture cylinder 602; wherein, the pressing block 603 is slidably connected with the pressing part 604. When it is necessary to clamp the workpiece, the electric push rod 601 extends, pushing the pressing block 603 to move downward. At the same time, the pressing block 603 presses the pressing part 604, so that the pressing part slides outward in the fixture cylinder 602, driving the internal support plate 605 to expand outward until the internal support plate 605 is in close contact with the inner surface of the workpiece and applies sufficient clamping force, so as to pick up the materials.

[0038] Furthermore, three pressing parts 604 are provided circumferentially. Setting the pressing parts 604 to three and evenly distributing them circumferentially can ensure that the force received by the material from the internal support plate during the pressing process is uniform and balanced, thereby improving the stability and reliability of material picking.

When it is necessary to unload the workpiece, the electric push rod 601 contracts, driving the pressing block 603 to move upward. Under the action of the first inclined chute 608606 and the second inclined chute 608607, the three pressing parts 604 and the internal support plates 605 connected thereto are driven to move inward, so as to unload the workpiece.

[0040] Furthermore, a chute 608 adapted to the pressing part 604 is provided on the outer wall of the fixture cylinder 602. Under the action of the chute 608, the pressing part 604 can move inward or outward stably.
