Description

Technical Field

[0001] This utility model relates to the field of graphite processing fixture technology, specifically to a flip-up fixture for graphite processing. Background Technology

[0002] Graphite is an allotrope of carbon that burns in oxygen to produce carbon dioxide. It is chemically stable, corrosion-resistant, and does not readily react with acids or alkalis. During graphite processing, it requires clamping for fixation. Patent CN202421699816.3 discloses a reversible clamp for graphite processing, in which a first ratchet assembly engages with a first pawl assembly, and a second ratchet assembly engages with a second pawl assembly. This allows the clamp to change the size of graphite it can hold by altering the engagement position of the ratchet and pawl during graphite lifting and flipping. However, the clamping components are inconvenient to disassemble and assemble during use, making it difficult to change clamps for different types of graphite. Therefore, we propose a reversible clamp for graphite processing. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a flip-up fixture for graphite processing.

[0004] The technical solution adopted by this utility model to solve its technical problem is a flip-up fixture for graphite processing, including an X-type hinge frame. The power output end surface of the X-type hinge frame is hinged to an adjustable straight arm body through a ratchet assembly. There are two sets of straight arms bodies. An adjustable T-shaped rod is slidably installed on the inner side of the straight arm body. The outer periphery of the T-shaped rod is provided with pin holes for limiting the position. There are multiple sets of pin holes. A screw pin is screwed onto the outer periphery of the straight arm body and screwed into the pin hole. The end of the T-shaped rod away from the straight arm is rotatably mounted with a cylinder seat located inside the T-shaped rod via a bearing, and a screw for support is inserted into the inner side of the cylinder seat. Both sets of screws are fitted with clamps for graphite limiting on their opposite sides, and a screw seat that abuts against the cylinder seat is screwed onto the end of the screw away from the clamp.

[0005] By adopting the above technical solution, during the use of the graphite processing flip-top fixture, the screw seat on the outer periphery can be unscrewed and separated from the screw. Then, the clamping plate can be removed and the screw can be separated from the cylinder seat, so that the clamping plate can be disassembled and replaced. It is convenient to replace it according to the specifications and shape of the graphite being clamped. The operation is simple and convenient. When using the clamping plate to limit and clamp graphite, the T-shaped rod inside the straight arm body can be pulled and extended from the straight arm body, thereby extending the distance between the clamping plate and the straight arm body. This facilitates more stable limiting and clamping of the graphite. After adjustment, simply rotate the screw on the outer periphery of the straight arm body to screw the screw through the straight arm body and into the pin hole on the outer periphery of the T-shaped rod. This makes it easy to lock and fix the position of the adjusted T-shaped rod, facilitating the use of the clamping plate and enabling it to limit and clamp the graphite.

[0006] Specifically, the outer periphery of the cylinder seat is provided with a toothed groove for limiting the position, and the outer periphery of the T-shaped rod is screwed with a hexagonal pin that abuts against the toothed groove.

[0007] By adopting the above technical solution, the hexagonal pin screwed on the outer periphery of the T-shaped rod can easily abut and engage with the toothed groove on the outer periphery of the cylinder seat, which facilitates the limiting and locking of the cylinder seat inside the T-shaped rod that can rotate on its own, so that the cylinder seat can be limited and fixed without needing to rotate.

[0008] Specifically, the inner circumference of the cylinder seat is integrally constructed with an arc-shaped strip for limiting the position, and there are multiple sets of arc-shaped strips. The outer circumference of the screw is provided with an arc-shaped groove that matches the arc-shaped strip, and there are multiple sets of arc-shaped grooves.

[0009] By adopting the above technical solution, the arc-shaped strip on the inner circumference of the cylinder seat and the arc-shaped groove on the outer circumference of the screw fit together, which facilitates the improvement of the stability when the screw and the cylinder seat are connected.

[0010] Specifically, a washer located on the outer periphery of the screw is snapped onto one end of the screw seat near the cylinder seat.

[0011] By adopting the above technical solution, the washer can improve the stability of the screw seat when limiting the screw.

[0012] Specifically, the end of the clamping plate near the cylinder seat is fitted with a rubber ring located on the outer periphery of the screw.

[0013] By adopting the above technical solution, the rubber ring has a certain elasticity, thereby improving the stability when the clamping plate and the cylinder seat are connected to each other, and reducing the damage caused by friction between the two.

[0014] Specifically, the outer circumference of the T-shaped rod is integrally constructed with protrusions that fit into the inner circumference of the straight arm, and there are multiple sets of protrusions.

[0015] By adopting the above technical solution, the multiple sets of protrusions on the outer periphery of the T-shaped rod can fit into the groove on the inner periphery of the straight arm, which facilitates the improvement of the stability during adjustment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The technical solution of this application, through the design of a straight arm body, a T-shaped rod, a pin hole, and a screw pin, allows the T-shaped rod inside the straight arm body to be pulled and extended out of the straight arm body when the graphite is clamped using the clamping plate. This extends the distance between the clamping plate and the straight arm body, facilitating more stable clamping of the graphite. Furthermore, once adjusted, simply rotating the screw pin on the outer circumference of the straight arm body allows the screw pin to thread through the straight arm body and engage with the pin hole on the outer circumference of the T-shaped rod. This facilitates locking and fixing the adjusted position of the T-shaped rod, making the clamping plate easy to use and enabling it to clamp the graphite.

[0017] 2. The technical solution of this application, through the design of the cylinder seat, screw, clamping plate and rotating seat, allows the rotating seat on the outer periphery of the screw to be unscrewed and separated from the screw during the use of the graphite processing flip-up fixture. Then the clamping plate can be pulled out and the screw can be separated from the cylinder seat, so that the clamping plate can be disassembled and replaced. This makes it convenient to replace according to the specifications and shape of the clamped graphite, and the operation is simple and convenient. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1-3This utility model provides a technical solution: a flip-up fixture for graphite processing, including an X-shaped hinge frame 1. The power output end surface of the X-shaped hinge frame 1 is hinged to an adjustable straight arm 2 via a ratchet assembly. There are two sets of straight arms 2. An adjustable T-shaped rod 3 is slidably installed on the inner side of the straight arm 2. The outer periphery of the T-shaped rod 3 is provided with pin holes 4 for limiting, and there are multiple sets of pin holes 4. A screw pin 5 is screwed onto the outer periphery of the straight arm 2 and is screwed into the pin hole 4. A cylindrical seat 6 located inside the T-shaped rod 3 is rotatably installed at the end of the T-shaped rod 3 away from the straight arm 2 via a bearing. A screw rod 7 for support is inserted into the inner side of the cylindrical seat 6. A clamping plate 8 for graphite limiting is assembled on the opposite side of the two sets of screw rods 7. A screw seat 9 that abuts against the cylindrical seat 6 is screwed onto the end of the screw rod 7 away from the clamping plate 8.

[0022] When using the graphite processing flip-top fixture, the screw seat 9 on the outer periphery of the screw 7 can be unscrewed and separated from the screw 7. Then the clamping plate 8 can be pulled out and the screw 7 can be separated from the cylinder seat 6. Thus, the clamping plate 8 can be disassembled and replaced, which is convenient to replace according to the specifications and shape of the clamped graphite. The operation is simple and convenient. When using clamping plate 8 to limit and clamp graphite, the T-shaped rod 3 inside the straight arm 2 can be pulled and extended from the straight arm 2, thereby extending the distance between clamping plate 8 and straight arm 2. This facilitates more stable limiting and clamping of graphite later. After adjustment, simply rotate the screw pin 5 on the outer circumference of straight arm 2 so that the screw pin 5 screws through straight arm 2 and engages with the pin hole 4 on the outer circumference of T-shaped rod 3. This makes it easy to lock and fix the position of T-shaped rod 3 after adjustment, making it convenient to use clamping plate 8 and enabling clamping and clamping of graphite.

[0023] like Figure 3 As shown, the outer periphery of the cylinder seat 6 is provided with a toothed groove 11 for limiting the position, and the outer periphery of the T-shaped rod 3 is screwed with a hexagonal pin 10 that abuts against the toothed groove 11.

[0024] In use, the hexagonal pin 10 screwed onto the outer periphery of the T-shaped rod 3 can easily engage with the toothed groove 11 on the outer periphery of the cylindrical seat 6, which facilitates the limiting and locking of the cylindrical seat 6 inside the T-shaped rod 3, so that the cylindrical seat 6 can be limited and fixed when it is not necessary to rotate.

[0025] like Figure 1 and Figure 2 As shown, the inner circumference of the cylinder seat 6 is integrally constructed with an arc-shaped strip 12 for limiting the position, and there are multiple sets of arc-shaped strips 12. The outer circumference of the screw 7 is provided with an arc-shaped groove 13 that matches the arc-shaped strip 12, and there are multiple sets of arc-shaped grooves 13.

[0026] During use, the arc-shaped strip 12 on the inner circumference of the cylinder seat 6 and the arc-shaped groove 13 on the outer circumference of the screw 7 fit together, which facilitates the improvement of the stability when the screw 7 and the cylinder seat 6 are connected.

[0027] like Figure 1 and Figure 2 As shown, a washer 14 located on the outer periphery of the screw 7 is snapped onto one end of the screw seat 9 near the cylinder seat 6.

[0028] When in use, washer 14 helps to improve the stability of screw seat 9 when limiting screw 7.

[0029] like Figure 2 As shown, the end of the clamping plate 8 near the cylinder seat 6 is fitted with a rubber ring 15 located on the outer periphery of the screw 7.

[0030] When in use, the rubber ring 15 has a certain degree of elasticity, thereby improving the stability of the connection between the clamping plate 8 and the cylinder seat 6, and reducing the damage caused by friction between the two.

[0031] like Figure 2 As shown, the outer circumference of the T-shaped rod 3 is integrally constructed with a protrusion 16 that matches the inner circumference of the straight arm body 2, and there are multiple sets of protrusions 16.

[0032] When in use, the multiple sets of protrusions 16 on the outer periphery of the T-shaped rod 3 can fit into the groove on the inner periphery of the straight arm body 2, which facilitates the improvement of the stability of the two during adjustment.

[0033] The working principle and usage process of this utility model are as follows: First, install the corresponding structural components in suitable positions, and connect the X-shaped hinge frame 1 to the existing hoisting structure to facilitate subsequent clamping of the graphite using a fixture. During the use of the reversible fixture for graphite processing, the screw seat 9 on the outer periphery of the screw 7 can be unscrewed and separated from the screw 7. Then, the clamping plate 8 can be removed, separating the screw 7 from the cylinder seat 6, allowing for disassembly and replacement of the clamping plate 8. This facilitates replacement according to the specifications and shape of the clamped graphite. The operation is simple and convenient, and the reverse operation facilitates the installation of the clamping plate 8. Simultaneously, when using the clamping plate 8 to limit and clamp the graphite, it can pull the T-shaped rod 3 inside the straight arm body 2 and make the T-shaped rod 3 extend out of the straight arm body 2, thereby extending the distance between the clamping plate 8 and the straight arm body 2. This facilitates more stable limiting and clamping of the graphite in the future. After adjustment, simply rotate the screw pin 5 on the outer periphery of the straight arm body 2 so that the screw pin 5 screws through the straight arm body 2 and engages with the pin hole 4 on the outer periphery of the T-shaped rod 3. This makes it easy to lock and fix the position of the adjusted T-shaped rod 3, which facilitates the use of the clamping plate 8. This allows the clamping plate 8 to limit and clamp the graphite, thereby improving the versatility of the graphite processing fixture.
