Description

Technical Field

[0001] The utility model belongs to the technical field of air pump structures, and more specifically, particularly relates to an internal air pump structure of a silicon carbide plasma cutter. Background Technique

[0002] Plasma cutters are cutters widely used in various industries such as automobiles, locomotives, and pressure vessels. Currently, most existing plasma cutters are internally equipped with air pumps.

[0003] When the existing internal air pump is in use, it needs to be connected to an air pipe. During the use process, due to the gravity of the air pipe, air leakage easily occurs at the air pipe connection, affecting the use; when the existing device is installed inside the cutter housing, it needs to be fixed with multiple bolts, and the disassembly and assembly efficiency is relatively low. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an internal air pump structure of a silicon carbide plasma cutter to solve the problems that when the existing internal air pump is in use, it needs to be connected to an air pipe, and during the use process, air leakage easily occurs at the air pipe connection under the influence of the gravity of the air pipe, affecting the use; when the existing device is installed inside the cutter housing, it needs to be fixed with multiple bolts, and the disassembly and assembly efficiency is relatively low.

[0005] The purpose and effect of the internal air pump structure of a silicon carbide plasma cutter of the utility model are achieved by the following specific technical means:

[0006] An internal air pump structure of a silicon carbide plasma cutter includes a cutter housing; four socket seats are welded to the bottom end surface of the inner wall of the cutter housing, two threaded seats are welded to the bottom end surface of the inner wall of the cutter housing, and an installation component is installed inside the cutter housing.

[0007] Further, the installation component is composed of a seat body, a support block, a fixed seat, a first fixing screw, and a holding hole. An air pump main body is fixed on the seat body, two support blocks are fixed on the bottom end surface of the seat body, both support blocks are in contact with the bottom end surface of the cutter housing, and there is a gap between the bottom end surface of the seat body and the bottom end surface of the inner wall of the cutter housing under the support of the two support blocks.

[0008] Further, a holding hole is opened on the top end surface of the seat body, and the holding hole is a rectangular hole structure.

[0009] Further, two fixed seats are inserted into the seat body, and each fixed seat is welded by two cylindrical rods and a rectangular block. The left fixed seat is inserted into the left two socket seats, and the right fixed seat is inserted into the right two socket seats.

[0010] Further, a first fixing screw is inserted into each of the fixing seats, and the two first fixing screws are respectively threadedly connected in the two threaded seats.

[0011] Further, a connecting pipe is connected to the air pump main body, and the connecting pipe is threadedly connected to the joint of the air pipe; an auxiliary assembly is installed on the cutting machine housing. The auxiliary assembly consists of a support seat and a second fixing screw. A support seat is welded to the right end face of the cutting machine housing, and the air pipe is supported on the support seat.

[0012] Further, a second fixing screw is threadedly connected to the support seat. When the second fixing screw is tightened, the left end of the second fixing screw abuts against the connection head of the air pipe.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In this application, through the setting of the installation assembly, on the one hand, when disassembling the seat body, the two first fixing screws are removed, and the two fixing seats are pulled out upwards. At this time, the seat body can be taken out from the cutting machine housing. Compared with the existing fixing method using four screws, the disassembly and assembly are more convenient and rapid; on the other hand, when taking out the seat body from the cutting machine housing, directly insert the hand into the holding hole and drag out the seat body, and the disassembly is convenient.

[0015] In this application, through the setting of the auxiliary assembly, on the one hand, by supporting the air pipe with the support seat, the force on the connection part between the air pipe connection head and the connecting pipe can be avoided, thereby avoiding air leakage at the connection part between the air pipe connection head and the connecting pipe; on the other hand, after the second fixing screw is tightened, the connection head of the air pipe can be prevented from loosening, thereby avoiding air leakage.

[0030] Embodiment 1:

[0031] As shown in Figure 1 to Figure 6 shown:

[0032] The present utility model provides an internal air pump structure for a silicon carbide plasma cutting machine, including a cutting machine housing 1; four socket joints 101 are welded to the bottom end surface of the inner wall of the cutting machine housing 1, two threaded seats 102 are welded to the bottom end surface of the inner wall of the cutting machine housing 1, and an installation component 2 is installed inside the cutting machine housing 1.

[0033] Among them, the installation component 2 is composed of a seat body 201, a support block 202, a fixed seat 203, a first fixing screw 204, and a holding hole 205. An air pump main body 3 is fixed on the seat body 201. Two support blocks 202 are fixed to the bottom end surface of the seat body 201. Both support blocks 202 are in contact with the bottom end surface of the cutting machine housing 1. Under the support of the two support blocks 202, there is a gap between the bottom end surface of the seat body 201 and the bottom end surface of the inner wall of the cutting machine housing 1. When removing the seat body 201 from the cutting machine housing 1, the hand can be inserted under the seat body 201 to take out the seat body 201 from the cutting machine housing 1, which facilitates the disassembly of the seat body 201.

[0034] Among them, a holding hole 205 is formed on the top end surface of the seat body 201. The holding hole 205 is a rectangular hole structure. When removing the seat body 201 from the cutting machine housing 1, the hand can be directly inserted into the holding hole 205 to drag out the seat body 201, and the disassembly is convenient.

[0035] Among them, two fixed seats 203 are inserted on the seat body 201. Each fixed seat 203 is welded by two cylindrical rods and a rectangular block. One fixed seat 203 on the left is inserted into the two socket joints 101 on the left, and one fixed seat 203 on the right is inserted into the two socket joints 101 on the right. When installing the seat body 201, the positioning of the seat body 201 inside the cutting machine housing 1 can be realized through the insertion of the fixed seat 203 into the socket joint 101.

[0036] Among them, a first fixing screw 204 is inserted on each fixed seat 203. The two first fixing screws 204 are respectively threadedly connected into the two threaded seats 102. When disassembling the seat body 201, the two first fixing screws 204 are removed, and the two fixed seats 203 are pulled out upward. At this time, the seat body 201 can be taken out from the cutting machine housing 1. Compared with the existing fixing by four screws, the disassembly and assembly are more convenient and fast.

[0037] Among them, a connecting pipe 301 is connected to the air pump main body 3, and the connecting pipe 301 is threadedly connected to the joint of the air pipe 302; an auxiliary component 4 is installed on the cutting machine housing 1. The auxiliary component 4 is composed of a support seat 401 and a second fixing screw 402. A support seat 401 is welded to the right end surface of the cutting machine housing 1. The air pipe 302 is supported on the support seat 401. During the use process, through the support of the support seat 401 for the air pipe 302, the force on the connection part between the connection head of the air pipe 302 and the connecting pipe 301 can be avoided, and thus the air leakage at the connection part between the connection head of the air pipe 302 and the connecting pipe 301 can be avoided.

[0038] Embodiment 2:

[0039] On the basis of Embodiment 1, a second fixing screw 402 is threadedly connected to the support base 401. When the second fixing screw 402 is tightened, the left end of the second fixing screw 402 abuts against the connector of the air pipe 302. After the second fixing screw 402 is tightened, the loosening of the connector of the air pipe 302 can be avoided, thereby preventing air leakage.

[0040] Working principle: During installation, the air pump main body 3 is fixed on the seat body 201, the seat body 201 is placed inside the cutting machine housing 1, and the two fixing seats 203 are inserted into the seat body 201. At this time, it is necessary to ensure that the two fixing seats 203 are inserted into the socket 101. The two first fixing screws 204 are passed through the two fixing seats 203 and tightened with the two threaded seats 102. The connector of the air pipe 302 is threadedly connected to the connecting pipe 301, and then the second fixing screw 402 is tightened.
