Description

Technical Field

[0001] The present application relates to the field of quartz crucible processing technology, and in particular to a pulling type high-temperature quartz crucible material taking mechanical arm. Background Art

[0002] The production of quartz crucible is to load high-purity quartz sand into a high-purity graphite mold that can be tilted at any angle, and then go through vacuum charging and molding, vacuum arc melting, and natural cooling before demolding to facilitate subsequent testing, sandblasting, cleaning and other processes.

[0003] In the prior art, the formed quartz crucible is mainly removed from the mold manually using tools such as pliers. However, the temperature of the quartz crucible just coming out of the production line is relatively high. Manually removing the quartz crucible at high temperature is risky and prone to work-related accidents. In addition, when using pliers to remove the crucible, the pliers need to be clamped on the inside and outside of the crucible, which can easily break the crucible. In addition, the direct contact between the pliers and the inner side of the crucible can easily contaminate the crucible. There is room for improvement. Utility Model Content

The clamping drive assembly drives the two clamping arms to rotate in a direction of approaching or moving away from each other.

[0009] By adopting the above technical solution, after the quartz crucible is formed, the operator tilts the mold and knocks the mold with a tool to make the quartz crucible partially extend out, and then slides the trailer in the direction close to the mold so that the supporting seat is located under the quartz crucible; the telescopic drive component drives the clamping claw to move in the direction close to the quartz crucible, and when the two clamping arms of the clamping claw are extended to both sides of the quartz crucible, the clamping drive component drives the two clamping arms to approach each other, so that the clamp is clamped on both sides of the quartz crucible; then the telescopic drive component drives the clamping claw together with the quartz crucible to move in the direction away from the mold, which can achieve the technical effect of automatically removing the high-temperature quartz crucible, effectively improve the efficiency of removing the quartz crucible, and avoid the risk caused by the operator manually removing the quartz crucible.

[0039] The clamping jaw 32 includes a clamping drive assembly 34 and two clamping arms 4. The ends of the two clamping arms 4 are respectively fixedly connected with clamping hoops 35. The two clamping arms 4 are rotatably installed on the driving end of the clamping drive assembly 34. The clamping drive assembly 34 drives the two clamping arms 4 to rotate in a direction close to or away from each other.

[0040] After the quartz crucible is formed, the operator tilts the mold and knocks the mold with a tool to make the quartz crucible partially extend out, and then slides the trailer 1 in the direction close to the mold so that the supporting seat 2 is located under the quartz crucible; the telescopic drive assembly 33 drives the clamping jaw 32 to move in the direction close to the quartz crucible, and when the two clamping arms 4 of the clamping jaw 32 are extended to both sides of the quartz crucible, the clamping drive assembly 34 drives the two clamping arms 4 to approach each other, so that the clamping hoop 35 is clamped on both sides of the quartz crucible; then the telescopic drive assembly 33 drives the clamping jaw 32 together with the quartz crucible to move in the direction away from the mold, which can achieve the technical effect of automatically removing the high-temperature quartz crucible, effectively improve the efficiency of removing the quartz crucible, and avoid the risk caused by the operator manually removing the quartz crucible. At the same time, the clamping jaw 32 does not contact the inner wall of the quartz crucible, which can effectively reduce the occurrence of breaking the crucible and contaminating the inner wall of the crucible.

[0041] Reference Figure 2 and Figure 3 The clamping jaw 32 includes a mounting plate 311, which is slidably arranged on the mounting frame 31. The clamping jaw 32 is installed on the mounting plate 311. The telescopic driving assembly 33 includes a rotating shaft 331 and a first motor 333. The rotating shaft 331 is rotatably mounted on the mounting plate 311. Driving gears 332 are fixedly installed at both ends of the rotating shaft 331.

[0042] In the process of moving the clamping jaw 32, the first motor drives the rotating shaft 331 to rotate, which can synchronously drive the driving gears 332 at both ends of the rotating shaft 331 to rotate, and the driving rack 36 on the frame is engaged with the driving gear 332, which can achieve the technical effect of driving the mounting plate 311 and the clamping jaw 32 installed on the mounting plate 311 to move. The first motor rotates in different directions, which can drive the mounting plate 311 and the clamping jaw 32 to move toward or away from the quartz pot.

[0043] Reference Figure 1 and Figure 2 , limiting slide grooves 37 are respectively provided on both sides of the mounting frame 31, and rollers 38 are rotatably installed at both ends of the mounting plate 311. The rollers 38 are embedded in the limiting slide grooves 37, and the wheel surfaces of the rollers 38 are in contact with the two opposite groove walls of the limiting slide grooves 37.

[0044] The roller 38 slides in the limiting slide groove 37, which can convert the sliding friction between the mounting plate 311 and the mounting frame 31 into rolling friction, effectively improving the smoothness of the sliding movement of the mounting plate 311. At the same time, because the roller 38 is embedded in the slide groove, the sliding track of the mounting plate 311 can be limited, reducing the occurrence of position deviation of the mounting plate 311.

[0045] Reference Figure 2 The clamping jaw 32 includes a connecting seat 321, which is rotatably mounted on the mounting plate 311, and the ends of the two clamping arms 4 are rotatably connected to the connecting seat 321; the clamping drive assembly 34 includes a screw rod 341 and a second motor 342, the screw rod 341 is rotatably mounted on the connecting seat 321, the second motor 342 is fixedly mounted on the connecting seat 321, the driving shaft end of the second motor 342 is fixedly connected to the screw rod 341, and a slide 343 is slidably mounted on the screw rod 341; connecting rods 344 are rotatably mounted on the upper and lower sides of the two clamping arms 4, and the ends of the connecting rods 344 away from the clamping arms 4 are rotatably connected to the slide 343.

[0046] The second motor 342 rotates to drive the slide 343 to slide on the screw rod 341 along the axial direction of the screw rod 341. Since the clamping arm 4 and the connecting rod 344 are both rotatably installed on the connecting seat 321, the connecting rod 344 can be synchronously driven to rotate. The change in the angle of the connecting rod 344 can drive the two clamping arms 4 to rotate, and the clamping arms 4 can be driven to rotate in the direction of approaching or moving away from each other, so as to realize the operation of clamping the quartz crucible and releasing the quartz crucible.

By matching and using the T-shaped plates and the rotating rods, the technical effect of rotating installation between the connecting seat 321 and the mounting plate 311 can be achieved.

[0048] Reference Figure 2 and Figure 3 A telescopic cylinder 39 is fixedly installed at the bottom of the mounting plate 311. A rod hole 312 is opened on the mounting plate 311 for the telescopic rod of the telescopic cylinder 39 to extend in and out. The rod hole 312 is located between the two T-plates.

[0051] In the embodiment of the present application, the top of the support seat 2 is formed with an inclined slope 21, which is inclined downward along the direction in which the quartz crucible slides out. The setting of the inclined slope 21 can guide the quartz crucible, so that the quartz crucible slides smoothly onto the support seat 2, completing the clamping action of the quartz crucible.

[0052] Furthermore, in the embodiment of the present application, in order to reduce the occurrence of position deviation and shaking of the quartz crucible, in the embodiment of the present application, an embedding groove adapted to the quartz crucible is formed on the inclined slope 21.

[0053] The implementation principle of a towing type high-temperature quartz crucible material taking mechanical arm of the embodiment of the present application is as follows: after the quartz crucible is formed, the operator tilts the mold and knocks the mold with a tool to make the quartz crucible partially extend, and then the sliding trailer 1 slides in the direction close to the mold, so that the supporting seat 2 is located below the quartz crucible; the telescopic driving component 33 drives the clamping claw 32 to move in the direction close to the quartz crucible, and when the two clamping arms 4 of the clamping claw 32 are extended to both sides of the quartz crucible, the clamping driving component 34 drives the two clamping arms 4 to approach each other, so that the clamping hoop 35 is clamped on both sides of the quartz crucible; then the telescopic driving component 33 drives the clamping claw 32 together with the quartz crucible to move in the direction away from the mold, which can achieve the technical effect of automatically taking out the high-temperature quartz crucible, effectively improve the efficiency of taking out the quartz crucible, and avoid the risk caused by the operator manually taking out the quartz crucible.
