[0019] In summary, the beneficial effects of the present utility model are as follows:

[0020] In the present utility model, when a person needs to sinter the electronic component body, the person can first move the upper limit plate. The upper limit plate drives the upper jig to move upward by means of the replacement structure until the upper limit plate slides out of the surface of the limit rod. Then the person sequentially places the electronic component body into the limit slots, and then the person moves the upper limit plate again so that the four limit rods and the two moving plates all slide into the inner wall of the upper limit plate. The moving plates are graphite plates, and the graphite plates have good heat conductivity and high temperature resistance, which can ensure that both ends of the electronic component body are heated evenly during sintering.

The guiding blocks at the upper ends of the limit rods can assist the person to slide the limit rods into the inner wall of the upper limit plate and improve the work efficiency of the person. By setting the auxiliary structure, the effect of limiting the electronic component body is achieved, which can effectively prevent the electronic component body from stretching around and deforming and uneven heating during the sintering process, thereby improving the qualified rate of the electronic component body after sintering.

[0021] In the present utility model, when a person needs to sinter electronic component bodies with different radii, the person can first rotate the threaded rod by means of the turntable. The threaded rod moves in the direction close to the upper limit plate, and the threaded rod drives the rotating column to move downward. When the rotating column abuts against the upper fixture, the rotating column drives the upper fixture to move downward. Then, the upper fixture drives the fixed block and the two mounting blocks to move downward until the mounting blocks slide out of the inner wall of the positioning groove. Then, the person moves the upper fixture in the horizontal direction, and the upper fixture drives the fixed block to move until the rotating column slides out of the mounting groove. At this time, the lower fixture is moved upward, and the lower fixture drives the two adjusting blocks to move upward until the adjusting blocks slide out of the inner wall of the connecting groove. Thus, the appropriate upper fixture and lower fixture can be replaced. The anti-slip grooves provided on the turntable can increase the friction between the person's hand and the turntable, and can prevent the person from slipping when rotating the turntable. By providing the replacement structure, it is achieved that the person can conveniently and quickly replace the upper fixture and the lower fixture, thereby accelerating the person's work efficiency and also improving the adaptability of the fixture.

An upper jig 213 is installed on the inner wall of the upper limiting plate 202 by means of a replacement structure 3. The upper limiting plate 202 is slidably connected with the moving plate 208. A number of limiting grooves 207 are opened on the inner walls of the upper jig 213 and the lower jig 206. By setting the auxiliary structure 2, when personnel need to sinter the electronic component body 1, the electronic component body 1 can be limited in multiple directions by rotating the lead screws 209 and moving the upper limiting plate 202, thereby improving the qualified rate of the electronic component body 1 after sintering. A rotating rod 210 is fixedly connected to the inner wall of the lead screw 209. The cross-section of the rotating rod 210 is circular. The rotating rod 210 can facilitate personnel to rotate the lead screw 209 and improve the operation convenience of personnel. A guiding block 212 is fixedly connected to the upper end of the limiting rod 211. The guiding block 212 is slidably connected with the upper limiting plate 202. The guiding block 212 can assist personnel in sliding the limiting rod 211 into the inner wall of the upper limiting plate 202 and improve the work efficiency of personnel. The moving plate 208 is a graphite plate, and the cross-section of the moving plate 208 is rectangular. The graphite plate has good thermal conductivity and high temperature resistance, which can ensure that both ends of the electronic component body 1 are heated evenly during sintering. A sliding rod 204 is fixedly connected to the inner wall of the auxiliary groove 203. The sliding rod 204 is slidably connected with the slider 205. The sliding rod 204 can limit the slider 205 and prevent the slider 205 from being displaced when sliding on the inner wall of the auxiliary groove 203.

[0035] Referring to Figures 7 to 9As shown in the figure, in this embodiment: The replacement structure 3 includes two positioning grooves 308, an engagement groove 303, and two connection grooves 301. The two positioning grooves 308 and the engagement groove 303 are both formed on the upper limit plate 202, and the two connection grooves 301 are formed on the lower limit plate 201. Two mounting blocks 309 are slidably connected to the inner wall of the positioning groove 308, and the two mounting blocks 309 are fixedly connected to the upper jig 213. A fixing block 304 is slidably connected to the inner wall of the engagement groove 303, and the fixing block 304 is fixedly connected to the upper jig 213. An installation groove 305 is formed in the inner wall of the fixing block 304, and a rotating column 306 is movably connected to the inner wall of the installation groove 305. The upper end of the rotating column 306 is fixedly connected to a threaded rod 307, and the threaded rod 307 is threadedly connected to the upper limit plate 202. The upper end of the threaded rod 307 is fixedly connected to a turntable 310. Two adjusting blocks 302 are slidably connected to the inner walls of the two connection grooves 301, and the two adjusting blocks 302 are fixedly connected to the lower jig 206. By providing the replacement structure 3, when personnel need to sinter electronic component bodies 1 of different shapes, they can rotate the turntable 310 and move the adjusting blocks 302 to quickly remove the upper jig 213 and the lower jig 206, thereby facilitating the rapid replacement of the upper jig 213 and the lower jig 206 by personnel, and thus improving the work efficiency of personnel. A plurality of anti-slip grooves 311 are formed in the inner wall of the turntable 310, and the anti-slip grooves 311 are evenly distributed on the turntable 310. The anti-slip grooves 311 can increase the friction between the personnel's hands and the turntable 310, and can prevent the personnel from slipping when rotating the turntable 310.

[0036] Working principle: When personnel need to sinter the electronic component body 1, they can first move the upper limit plate 202. The upper limit plate 202 drives the upper fixture 213 to move upward by means of the replacement structure 3 until the upper limit plate 202 slides out of the surface of the limit rod 211. Then the personnel can put the electronic component body 1 into the limit groove 207 in sequence. Then the personnel move the upper limit plate 202 again, so that the four limit rods 211 and the two moving plates 208 both slide into the inner wall of the upper limit plate 202. The moving plate 208 is a graphite plate, and the graphite plate has good thermal conductivity and high temperature resistance, which can ensure that both ends of the electronic component body 1 are heated evenly during sintering. Until the upper limit plate 202 is in contact with the lower limit plate 201, at this time, the limit groove 207 opened on the inner wall of the upper fixture 213 is in contact with the arc surface of the electronic component body 1. Then the personnel drive the lead screw 209 to rotate by means of the rotating rod 210. The two lead screws 209 drive the moving plates 208 to move towards each other respectively. The rotating rod 210 can facilitate the personnel to rotate the lead screw 209 and improve the operation convenience of the personnel. Then the two moving plates 208 drive the two sliders 205 to move towards the electronic component body 1 respectively. The slider 205 slides on the arc surface of the slide bar 204. The slide bar 204 can limit the slider 205 and prevent the slider 205 from being misaligned when sliding on the inner wall of the auxiliary groove 203. Until the two moving plates 208 are in contact with both sides of the lower fixture 206, at this time, the moving plate 208 just contacts both ends of the electronic component body 1. Then the personnel can sinter the electronic component body 1. The guide block 212 at the upper end of the limit rod 211 can assist the personnel to slide the limit rod 211 into the inner wall of the upper limit plate 202 and improve the work efficiency of the personnel. By setting the auxiliary structure 2, the effect of limiting the electronic component body 1 is achieved, which can effectively prevent the electronic component body 1 from stretching and deforming in all directions and uneven heating during the sintering process, thereby improving the qualified rate of the electronic component body 1 after sintering.

[0037] In addition, when personnel need to sinter the electronic component body 1 with different radii, the personnel can first drive the threaded rod 307 to rotate by means of the turntable 310. The threaded rod 307 moves in the direction close to the upper limit plate 202. The threaded rod 307 drives the rotating column 306 to move downward. When the rotating column 306 abuts against the upper jig 213, the rotating column 306 drives the upper jig 213 to move downward. Then the upper jig 213 drives the fixed block 304 and the two mounting blocks 309 to move downward until the mounting blocks 309 slide out of the inner wall of the positioning groove 308. Then the personnel move the upper jig 213 in the horizontal direction. The upper jig 213 drives the fixed block 304 to move until the rotating column 306 slides out of the mounting groove 305. At this time, move the lower jig 206 upward. The lower jig 206 drives the two adjusting blocks 302 to move upward until the adjusting blocks 302 slide out of the inner wall of the connecting groove 301. Thus, the appropriate upper jig 213 and lower jig 206 can be replaced. The anti-slip grooves 311 formed on the turntable 310 can increase the friction between the personnel's hand and the turntable 310, and can prevent the personnel from slipping when rotating the turntable 310. By providing the replacement structure 3, it is convenient for the personnel to quickly replace the upper jig 213 and the lower jig 206, thereby improving the work efficiency of the personnel and also enhancing the adaptability of the jig.
