Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, and more specifically, to a fixture and a robot for coke sample preparation. Background Art

[0002] Coke is primarily used in ironmaking, and accurate analysis of its particle size, M40, and M10 is crucial for guiding blast furnace production. Traditional coke sampling and analysis relies on manual analysis. After the sampler completes sampling, manual screening, drumming, and discarding are required. Sample preparation also requires manual crushing and pulverization, which is not only labor-intensive but also noisy and prone to dust inhalation, impacting the health of operators. Currently, there are some highly automated coke sampling systems on the market for coke sampling, sample preparation, and analysis. These systems utilize robotic systems, with equipment such as reduction devices, crushing devices, grinding devices, and drying devices positioned around them. The robots are used to move samples between the various devices. However, there is currently a lack of robots specifically designed for coke sampling, and existing robotic systems are difficult to directly apply to coke sampling. Utility Model Content

[0034] The present invention will be further described in detail below with reference to the embodiments so that those skilled in the art can implement the invention with reference to the description.

[0035] It should be noted that, in the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a fixture for coke sampling, comprising:

[0037] Mounting seat;

[0038] A driving mechanism 1, which is arranged on the mounting seat;

[0039] Two clamping jaws 2 are arranged opposite to each other and are respectively connected to the driving mechanism 1. The driving mechanism 1 drives the two clamping jaws 2 to move closer to or away from each other.

[0040] A position detection mechanism is provided between the two clamping jaws 2 and connected to the mounting seat to detect the opening and closing state of the clamp.

[0041] In this embodiment, a driving mechanism 1 drives two relatively arranged clamping jaws 2 to move closer to or further away from each other, forming a clamping position between the two clamping jaws 2. The clamping position is used to clamp the tray containing the coke sample, thereby achieving the action of clamping or placing the tray. At the same time, a position detection mechanism is provided between the two clamping jaws 2, and the position detection mechanism is used to detect the opening and closing state of the clamp. When the two clamping jaws 2 approach each other until the distance between them is the minimum value, the clamping jaws 2 are unloaded, and the position detection mechanism can detect the position of the two clamping jaws 2. When the clamp is in use, the two clamping jaws 2 will move away from each other, and at this time the distance between them is greater than the minimum value, and the position detection mechanism cannot detect the position of the two clamping jaws 2. Therefore, it is possible to determine whether the clamping jaws 2 are in an open or closed state through the position detection mechanism.

[0042] Preferably, as another embodiment of the present invention, the fixture for coke sampling further comprises:

[0043] The guide mechanism is arranged on the mounting seat and is slidably connected to the clamping jaw 2.

[0044] In this embodiment, a guide mechanism defines the movement trajectory of the jaws 2, maintaining the stability of the jaws 2 during movement. Specifically, the guide mechanism includes: at least one linear guide rail 3, which is disposed on the mounting base along the movement direction of the jaws 2; and two sliders 4, each slidably disposed on the linear rail and respectively connected to the two jaws 2. The sliders 4 slide along the linear rails along their lengths, defining the movement trajectory of the sliders 4 and the jaws 2 connected thereto, providing some support for the movement of the jaws 2 and maintaining the stability of the jaws 2 during movement.

[0045] Preferably, as another embodiment of the present invention, in the fixture for coke sampling, two linear guide rails 3 are provided.

[0046] In this embodiment, two linear guide rails 3 are provided, and the two linear rails are arranged at an interval, and the sliders 4 thereon are used to guide the two ends of the clamping jaw 2, thereby further improving the stability of the clamping jaw 2 during movement.

[0047] Preferably, as another embodiment of the present invention, in the fixture for coke sampling, the position detection mechanism includes:

[0048] The proximity switch 5 is arranged between the two clamping jaws 2 and connected to the mounting base through a connecting base 6 .

[0049] In this embodiment, the position detection mechanism uses a proximity switch 5 for detection. When the proximity switch 5 detects a signal, the two clamping jaws 2 approach each other until the distance between them is the minimum, and the clamping jaws 2 are in a closed state. When the proximity switch 5 does not detect a signal, the distance between the two clamping jaws 2 is greater than the minimum value, and the clamping jaws 2 are in an open state.

[0050] Preferably, as another embodiment of the present invention, in the fixture for coke sampling, the connecting seat 6 is an L-shaped plate, one end of which is connected to the mounting seat, and the other end of which extends between the two clamping jaws 2 and is connected to the proximity switch 5.

[0051] In this embodiment, the connecting seat 6 is made of an L-shaped plate, one end of which is connected to the mounting seat, and the other end extends between the two clamping jaws 2, which can bypass the linear guide rail 3, thereby fixing the proximity switch 5 between the two clamping jaws 2.

[0052] Preferably, as another embodiment of the present invention, in the fixture for coke sampling, the driving mechanism 1 is a self-centering vise.

[0053] Preferably, as another embodiment of the present invention, in the fixture for coke sampling, the mounting seat includes:

[0054] Mounting plate 7;

[0056] In this embodiment, the mounting seat is composed of a mounting plate 7 and a mounting frame 8, which can fix the driving mechanism 1 in the mounting seat, and at the same time allow the output end of the driving mechanism 1 to pass through the mounting seat and connect with the clamping jaw 2.

[0057] Preferably, as another embodiment of the present invention, in the clamp for coke sampling, a cross-shaped clamping portion 9 is provided on each side of the clamping jaws 2 that are close to each other.

[0058] In this embodiment, a cross-shaped clamping portion 9 is provided on one side of the clamping jaws 2 that are close to each other, thereby reducing the area of ​​the clamping portion 9 and increasing the pressure when the contact surface contacts the tray. Figure 3 As described above, a clamping piece 12 is provided on the material tray 11, and two clamping jaws 2 clamp the clamping piece 12. Cross-shaped grooves 13 matching the clamping parts 9 of the two clamping jaws 2 are provided at both ends of the clamping piece 12. The clamping parts 9 are stuck in the cross-shaped grooves 13 to enhance the clamping effect of the two clamping jaws 2 and improve the stability of the clamping jaws 2 when clamping the material tray 11.

[0059] like Figure 4 As shown, the present invention also provides a robot for coke sampling, comprising a manipulator 10 and any one of the clamps described above, wherein the claw of the manipulator 10 is connected to the mounting seat.

[0060] In this embodiment, the manipulator 10 can adopt an existing articulated robot. The movement of each joint of the articulated robot is rotation, similar to a human arm. By driving the clamp to move and flip, the clamp can be moved between the reduction device, crushing device, grinding device, drying device and other equipment in the coke sampling system.
