Technical Field

[0001] The utility model relates to the technical field of graphite material sintering and processing equipment, and particularly relates to a clamping device for graphite material sintering and processing. Background Art

[0002] During the sintering and processing of graphite materials, a high-temperature-resistant crucible is required to hold the graphite materials and place them in a heating furnace for sintering and processing; due to the shape of the crucible, the crucible cannot be directly placed in the heating furnace for heating, and a clamping device needs to be used to clamp and limit the crucible to ensure that it is always in a vertical state during sintering in the heating furnace; most of the existing clamping devices adopt a support frame structure. Although this structure can support and limit the crucible, there are still the following deficiencies: the specifications and sizes of the crucibles are different. Each time during sintering and processing, a support frame suitable for the size of the crucible needs to be selected; after sintering is completed, the entire support frame needs to be taken out before the crucible can be removed, which is inconvenient to use and causes many troubles to the staff.

[0003] Therefore, this application provides a clamping device for graphite material sintering and processing to meet the requirements. Summary of the Utility Model

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] refer to Figure 1-5A clamping device for sintering and processing graphite materials, as shown, includes a chassis 1 and a placement plate 2. The chassis 1 is in a "冂"-shaped frame. The placement plate 2 is slidably connected to the chassis 1. A counterweight 11 for preventing tipping is provided on the left side of the chassis 1. The counterweight 11 is provided to avoid the problem that when the placement plate 2 slides out, it will drive the entire device to tilt. A clamping block 4 for limiting the placement plate 2 is provided on the right side of the chassis 1; the clamping block 4 is an L-shaped block, and a card slot 12 matching the size of the clamping block 4 is opened on the right side of the chassis 1; Side holes 5 are also opened on the front and rear sides of the chassis 1. The side holes 5 reduce the total mass of the chassis 1 and also facilitate the staff to move the entire device through the side holes 5.

[0025] A placement groove 10 for placing a crucible is opened on the placement plate 2. A sliding groove 6 communicating with the placement groove 10 is also opened on the placement plate 2. There are three groups of the sliding grooves 6, and they are arranged in a circular array around the placement groove 10;

[0026] In order to enable the device to clamp and limit crucibles of different specifications and sizes, a clamping rod 8 for clamping and limiting the crucible is provided in the sliding groove 6. The placement plate 2 is provided with a limiting mechanism for limiting the clamping rod 8; the limiting mechanism includes a sliding seat 7 and a plug pin 9. The sliding groove 6 is a T-shaped groove, and the sliding seat 7 is slidably connected in the sliding groove 6. The sliding seat 7 matches the size of the sliding groove 6. A rotating groove 71 is opened on the sliding seat 7. The clamping rod 8 is rotatably connected in the rotating groove 71. A through hole 72 matching the size of the plug pin 9 is also opened on the sliding seat 7. The plug pin 9 is slidably connected in the through hole 72. A pin hole 15 matching the size of the plug pin 9 is opened on the placement plate 2. The rotating groove 71 enables the clamping rod 8 to rotate on the sliding seat 7. The plug pin 9 limits the sliding seat 7 and also limits the clamping rod 8 so that it cannot rotate in the rotating groove 71. When the device is not in use, the clamping rod 8 can be rotated around the rotating groove 71 to make the clamping rod 8 retracted in the sliding groove 6, reducing the height dimension of the device and facilitating storage.

[0027] In order to clamp and limit the crucible more stably, the clamping rod 8 is an expansion rod, including a pressing rod 81 and a sliding rod 82. The sliding rod 82 is rotatably connected to the rotating groove 71. A sliding hole matching the size of the sliding rod 82 is opened on the pressing rod 81. A bolt 83 for limiting the sliding rod 82 is also engaged on the pressing rod 81. The sliding hole on the pressing rod 81 is opened at the bottom, and a convex edge is provided at the top of the pressing rod 81. The convex edge can tightly limit the crucible.

[0028] In order to facilitate the staff to take and place the crucible, a slide 13 is also provided on the base frame 1, and a slider 14 corresponding to the position and matching the size of the slide 13 is provided on the facing surface of the placement plate 2 and the base frame 1. The slider 14 is slidably connected to the slide 13, and a handle 3 for pulling is also provided on the right side of the placement plate 2. The combination of the slide 13 and the slider 14 enables the placement plate 2 to slide stably on the base frame 1.

[0029] The working principle of the utility model is as follows: during installation, the device is carried to the heating furnace through the side hole 5 on the side of the base frame 1, and the card block 4 is pushed upward to make it slide out of the card slot 12, thereby releasing the limit between the base frame 1 and the placement plate 2. The staff can use the handle 3 to pull the placement plate 2 to the right, so that it drives the slider 14 to slide in the slideway 13, and stops when the slider 14 slides to the right end of the slideway 13. Under the action of the counterweight 11, the placement plate 2 will not drive the base frame 1 to tilt to the right and turn over; the crucible to be sintered is placed in line with the placement slot 10, and the latch 9 is pushed upward to make it slide in the through hole 72 and slide out of the pin hole 15, thereby releasing the limit of the slide seat 7 in the slide slot 6. At this time, the bottom end of the latch 9 is located in the through hole 72, and the latch 9 also clamps the clamping rod 8 To limit the position, the clamping rod 8 is in a vertical state. First, the staff rotates the bolt 83 clockwise to release the limit between the pressure rod 81 and the slide rod 82, and moves the pressure rod 81 downward so that the pressure rod 81 presses and limits the top of the crucible, and then rotates the bolt 83 counterclockwise to limit the pressure rod 81 and the slide rod 82; secondly, push the slide seat 7 to drive the clamping rod 8 to move toward the crucible, and the three groups of clamping rods 8 contact and clamp the crucible, press the pin 9 downward to embed it into the pin hole 15, limit the slide seat 7, and complete the clamping and limiting of the crucible; reset the placement plate 2 to complete the installation, and start the heating furnace for heating and sintering operations; after sintering, when the crucible needs to be taken out, the crucible can be taken out by following the above-mentioned reverse steps.
