DETAILED DESCRIPTION

[0030] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0031] Example 1

[0032] A quality inspection fixture for carbon fiber crucible, such as Figure 1-Figure 3 As shown, it includes a base 1 and a mounting frame 201 fixedly mounted on the base 1. The mounting frame 201 is provided with an external clamping mechanism for clamping the crucible. The external clamping mechanism includes a pair of slide bars 202 slidably mounted on the mounting frame 201. The slide bars 202 can slide left and right along the mounting frame 201. The ends of the two slide bars 202 close to each other are fixedly mounted with clamping claws 203. Two groups of balls for contacting the outer wall of the crucible are rollingly mounted on the clamping claws 203, each group of two balls. A rotating frame 204 is rotatably mounted in the mounting frame 201. The mounting frame 201 is provided with a switching mechanism for the movement of the rotating frame 204. The rotating frame 204 is slidably mounted with a sliding frame A2 05, and is equipped with a driving assembly A206 connected to the sliding frame A205, the driving assembly A206 consists of a motor A and a screw, wherein the motor A is installed on the rotating frame 204, one end of the screw is rotatably connected to the rotating frame 204, and the other end is fixedly connected to the output shaft of the motor A, and is threadedly connected to the sliding frame A205 in a through-type manner, a bearing platform 207 is provided on the rotating frame 204, and a stepped groove matching the sliding frame A205 is provided at the bottom of the bearing platform 207, and a visual inspection device for quality inspection is located on the upper side of the bearing platform 207 (the visual inspection device is a prior art, not shown in the figure, and will not be repeated here), and an internal support mechanism for providing support for the crucible is provided on the mounting frame 201.

[0033] like Figure 3and Figure 4 As shown, the external clamping mechanism also includes a guide column 208 rotatably mounted on the sliding frame A205, the guide column 208 movably passes through the rotating frame 204, the top of the guide column 208 is fixedly connected to the supporting platform 207, a guide groove is opened on the guide column 208, the guide groove is spiral, and a hemispherical block 209 matching the guide groove is fixedly mounted on the rotating frame 204. When the guide column 208 moves relative to the rotating frame 204, the guide column 208 can be rotated through the cooperation between the hemispherical block 209 and the guide groove.

[0034] like Figure 5 and Figure 6 As shown, an H-shaped plate 302 driven by a hydraulic cylinder 301 is installed in the mounting frame 201 for sliding along the front-to-back direction. The hydraulic cylinder 301 is installed on the mounting frame 201. A pair of telescopic rods 303 are hinged on the upper front side of the H-shaped plate 302. The outer wall of the sliding rod 202 is rotatably sleeved with a connecting block 304 hinged to the telescopic end of the telescopic rod 303. A tension spring A is provided between the side of the connecting block 304 away from the clamping jaw 203 and the mounting frame 201.

[0035] like Figure 6 As shown, a pair of locking rods 401 are installed in the mounting frame 201 for sliding along the front-to-back direction, a compression spring A is provided between the rear side of the locking rod 401 and the mounting frame 201, and the outer wall of the slide bar 202 has an annular groove matching the locking rod 401. When the locking rod 401 is stuck in the annular groove, the slide bar 202 can be limited.

[0036] After the extension rod 303 is extended to the limit, the H-shaped plate 302 is pushed forward by the extension rod 303 and the two connecting blocks 304 are retracted. The connecting blocks 304 are forced to slide the slide bar 202 horizontally, and the tension spring A between the connecting block 304 and the mounting frame 201 is extended. The slide bar 202 drives the clamping jaws 203 to move, and the two clamping jaws 203 move closer to each other. Then, the two sets of balls on the clamping jaws 203 contact the outer wall of the crucible. At this time, the annular groove of the slide bar 202 is aligned with the adjacent locking rod 401, and the compression spring A is released to make the locking rod 401 slide forward. After the locking rod 401 slides, it is locked in the annular groove of the corresponding slide bar 202 to limit the slide bar 202. By limiting the clamping jaws 203, the two clamping jaws 203 can always keep the outer wall of the crucible clamped by the two groups of balls thereon, and then the motor A in the driving component A206 is controlled to drive the screw to rotate. The sliding frame A205 slides upward along the rotating frame 204 under the action of the screw, and drives the supporting platform 207 and the guide column 208 to lift upward, and the supporting platform 207 pushes the crucible to lift upward, and the hemispherical block 209 squeezes the guide groove of the guide column 208, so that the guide column 208 drives the crucible to rotate through the supporting platform 207. The two groups of balls on the clamping jaws 203 roll due to the friction of the outer wall of the crucible, thereby realizing that the crucible can be lifted upward and rotated at the same time, and the crucible is lifted relative to the visual inspection equipment, and the visual inspection equipment can take pictures of the inner wall of the crucible for quality inspection, and then the motor A in the driving component A206 is controlled to drive the screw to rotate in the opposite direction, so that the supporting platform 207 drives the crucible to drop and reset, completing the quality inspection work of photographing the inner wall of the crucible.

[0037] Example 2

[0038] like Figure 7-Figure 9As shown, the switching mechanism includes a rocker 501 that is slidably mounted on the slide bar 202 along the left and right directions. A sleeve is fixedly mounted on the side where the two rocker bars 501 are close to each other. The sleeve is rotatably connected to the mounting frame 201. A driving component B502 for driving the left rocker bar 501 to move is mounted on the mounting frame 201. The driving component B502 consists of a motor B, a gear and an arc-shaped rack, wherein the motor B is mounted on the mounting frame 201, the gear is fixedly mounted on the output shaft of the motor B, the arc-shaped rack is fixedly mounted on the left rocker bar 501 and meshes with the gear, and a sliding frame B503 is slidably mounted on the mounting frame 201 along the front-back direction. A compression spring B is arranged between B503 and the mounting frame 201, and a pair of guide wheel groups are installed on the mounting frame 201. One end of the steel cable is fixedly installed on the rear end of the rocker arm 501, and the other end of the steel cable passes around the guide wheel group and is fixedly installed on the sliding frame B503. When the rocker arm 501 rotates, the sliding frame B503 can be pulled forward by the steel cable. A sliding shaft 504 is slidingly installed on the sliding frame B503 in the front and rear directions, and a disc 5041 is rotatably installed on the rear end of the sliding shaft 504. A tension spring B is arranged between the disc 5041 and the sliding frame B503, and the front end of the sliding shaft 504 has a cylindrical groove, and a T-shaped shaft 505 is elastically slidably installed in the cylindrical groove.

[0039] like Figure 9 and Figure 10 As shown, the internal support mechanism includes a push plate 601 fixedly installed on the top of the H-shaped plate 302, and a sliding ring 602 is fixedly installed on the outer wall of the T-shaped shaft 505 through a pair of connecting rods. The sliding ring 602 is slidably sleeved on the sliding shaft 504, and the sliding ring 602 cooperates with the push plate 601. Three connecting rods A701 are hinged on the T-shaped shaft 505, and three groups of connecting rods B702 are hinged on the sliding shaft 504, each group of two, and each connecting rod A701 and a corresponding group of connecting rods B702 are hinged to a support bar 703.

[0040] like Figure 10 As shown, a through groove is provided at the bottom of the outer wall of the sliding shaft 504, and an elastic sliding rod 801 is installed in the through groove to slide along the circumference of the sliding shaft 504. A wedge block A802 that slides with the through groove is fixedly installed at the bottom of the elastic sliding rod 801. The wedge block A802 is used in conjunction with the sliding ring 602. When the vertical surface of the wedge block A802 contacts the sliding ring 602, the sliding ring 602 can be limited.

[0041] like Figure 10 As shown, a wedge block B901 that slides with the through slot is fixedly installed at the bottom of the elastic sliding rod 801. The wedge block B901 is used in conjunction with the push plate 601. When the push plate 601 contacts the wedge block B901, the elastic sliding rod 801 can be lifted upward.

[0042] like Figure 11As shown, a friction plate 1001 that cooperates with the H-shaped plate 302 is fixedly installed at the bottom of the locking rod 401. Only when the H-shaped plate 302 moves backward relative to the locking rod 401 will friction be generated between the H-shaped plate 302 and the locking rod 401.

[0043] Initially, the H-shaped plate 302 is located at the rear side of the friction plate 1001. When the H-shaped plate 302 slides forward, the top of the H-shaped plate 302 contacts the bottom of the friction plate 1001, and no friction is generated between the friction plate 1001 and the top of the H-shaped plate 302. After completing the quality inspection of the inner wall of the crucible, the motor B in the control drive component B502 drives the gear to rotate, and the gear drives the left rocker 501 to rotate downward through the arc-shaped rack. The left rocker 501 drives the left clamping claw 203 to rotate through the corresponding slide bar 202, and drives the rotating frame 204 to rotate. The rotating frame 204 drives the right clamping claw 203 and the rocker 501 to rotate through the right slide bar 202, and drives the supporting platform 207 to move through the sliding frame A205. The two sets of balls on the supporting platform 207 and the two clamping jaws 203 cooperate to rotate the crucible, and the opening direction of the crucible rotates toward the T-shaped shaft 505. At the same time, the two rocker arms 501 pull the sliding frame B503 through the steel cables thereon. The sliding frame B503 is forced to drive the sliding shaft 504 to move forward through the tension spring B, and the sliding shaft 504 drives the T-shaped shaft 505 to move forward. The T-shaped shaft 505 and the sliding shaft 504 respectively drive the three support bars 703 to move forward through three connecting rods A701 and three sets of connecting rods B702. At the same time, the T-shaped shaft 505 drives the sliding ring 602 forward through a pair of connecting rods. Then the top of the push plate 601 contacts the front inclined surface of the wedge block B901. The wedge block B901 is forced to completely retract into the through groove and drives the elastic sliding The rod 801 elastically contracts and slides, and the elastic sliding rod 801 drives the wedge A802 to completely retract into the through groove until the top of the push plate 601 contacts the rear inclined surface of the wedge B901. The elastic sliding rod 801 gradually slides back and drives the wedge A802 and the wedge B901 to reset until the rotating frame 204 rotates to a horizontal state. At this time, the three support bars 703 are all located in the crucible, and the front end of the sliding ring 602 contacts the rear side of the push plate 601. Then the movable end of the hydraulic cylinder 301 is controlled to contract, and the movable end of the hydraulic cylinder 301 drives the H-shaped plate 302 to slide backward, and the H-shaped plate 302 drives the push plate 601 to move backward. Since the elastic force between the T-shaped shaft 505 and the sliding shaft 504 is less than the elastic force of the tension spring B, the push plate 601 can The sliding ring 602 is able to slide backward relative to the sliding shaft 504. The sliding ring 602 drives the T-shaped shaft 505 to elastically shrink and slide through a pair of connecting rods. The T-shaped shaft 505 drives the three connecting rods A701 to push the three support bars 703. The support bars 703 are forced to drive the corresponding two connecting rods B702 to rotate. The three support bars 703 move away from each other under the action of the connecting rods A701 and B702. Then the inner wall of the sliding ring 602 contacts and squeezes the wedge A802. The wedge A802 is forced to drive the elastic sliding rod 801 to elastically shrink and slide. The wedge A802 is completely retracted into the through groove. The elastic sliding rod 801 drives the wedge B901 to completely retract into the through groove until the inner wall of the sliding ring 602 is no longer in contact with the wedge A802.The elastic sliding rod 801 slides elastically to reset and drives the wedge A802 and the wedge B901 to reset. The vertical surface of the wedge A802 contacts the outer wall of the sliding ring 602, thereby limiting the sliding ring 602. At this time, the three support bars 703 are all in contact with the inner wall of the crucible and squeezed to achieve internal support and clamping of the crucible. At the same time as the sliding ring 602 contacts the wedge A802, the top of the H-shaped plate 302 contacts the bottom of the friction plate 1001. At this time, friction is generated between the friction plate 1001 and the top of the H-shaped plate 302. The friction plate 1001 is forced to drive the locking rod 401 to slide backward. When the three support bars 703 are in contact with and squeezed against the inner wall of the crucible, the locking rod 401 is separated from the annular groove of the corresponding slide bar 202, and the tension spring A contracts to drive the slide bar 202 to slide through the connecting block 304. The slide bar 202 drives the clamping claw 203 away from the crucible, and the clamping claw 203 does not block the outer wall of the crucible, so that the visual inspection equipment can take pictures of the outer wall of the crucible for quality inspection. When the H-shaped plate 302 is reset, the compression spring A is slowly released to drive the locking rod 401 to slide forward and reset. The locking rod 401 drives the friction plate 1001 to reset, and then controls the motor A in the drive component A206 to drive The movable screw rotates, and the sliding frame A205 slides backward along the rotating frame 204 under the action of the screw, and drives the supporting platform 207 and the guide column 208 to slide backward. The supporting platform 207 drives the crucible to move backward. The hemispherical block 209 squeezes the guide groove of the guide column 208, so that the guide column 208 drives the crucible to rotate through the supporting platform 207, thereby achieving the crucible sliding backward and rotating at the same time. The inner wall of the crucible rubs against the three support bars 703, so that the support bars 703 drive the sliding shaft 504 to rotate through the connecting rod B702, and the sliding shaft 504 drives the disk 5041 relative to the sliding frame B503 moves backward, and tension spring B is stretched under force. As the crucible slides backward and rotates simultaneously, the visual inspection equipment can fully inspect the crucible's outer wall. Then, the motor A in the drive assembly A206 is controlled to drive the lead screw to rotate in the opposite direction, thereby moving the support platform 207 forward. The tension spring B contracts, driving the slide shaft 504 to slide forward through the disk 5041, thereby moving the three support bars 703 forward. The three support bars 703 drive the crucible forward, ensuring that the crucible is always in contact with the support platform 207 until the tension spring B is fully contracted, thus completing the image quality inspection of the crucible's outer wall.

[0044] Then the movable end of the hydraulic cylinder 301 is controlled to extend, so that the two clamping jaws 203 move closer to each other and the push plate 601 moves forward. After the push plate 601 moves away from the sliding ring 602, it squeezes the wedge block B901. Then the top of the push plate 601 contacts the front inclined surface of the wedge block B901. The wedge block B901 is forced to completely retract into the through groove and drive the elastic sliding rod 801 to elastically retract and slide. The elastic sliding rod 801 drives the wedge block A802 to completely retract into the through groove, and the wedge block A802 no longer contacts the sliding ring 602. , the sliding ring 602 is free from the restriction, the T-shaped shaft 505 is elastically released and slides back to its original position, and the sliding ring 602 is driven to slide forward relative to the sliding shaft 504 through a pair of connecting rods. The T-shaped shaft 505 and the sliding ring 602 respectively drive the three support bars 703 to move closer to each other through the connecting rod A701 and the connecting rod B702. At this time, the two sets of balls on the two clamping jaws 203 have contacted the outer wall of the crucible, completing the clamping of the crucible, and the locking rod 401 is stuck in the annular groove of the sliding rod 202, thereby limiting the two clamping jaws 203, and then controlling The motor B in the control drive assembly B502 drives the gear to rotate in the opposite direction, thereby causing the two rocker arms 501, the rotating frame 204, the two clamping jaws 203 and the two slide bars 202 to rotate and reset. The rotating frame 204 drives the supporting platform 207 to move and reset through the sliding frame A205. The supporting platform 207 cooperates with the two sets of balls on the two clamping jaws 203 to rotate and reset the crucible. As the two rocker arms 501 rotate, the compression spring B is gradually released to drive the sliding frame B503 to slide and reset. The sliding frame B503 drives the sliding shaft 501 through the tension spring B. 4 moves to reset, thereby causing the three support bars 703 to move to reset, and then controlling the movable end of the hydraulic cylinder 301 to retract, causing the H-shaped plate 302 to move backward. Subsequently, the top of the H-shaped plate 302 contacts the bottom of the friction plate 1001, causing the locking rod 401 to slide backward and disengage from the annular groove of the corresponding slide bar 202. When the H-shaped plate 302 is reset, the compression spring A is slowly released to drive the locking rod 401 to slide forward and reset. The locking rod 401 drives the friction plate 1001 to reset, and the crucible is removed, completing the quality inspection of the inner and outer walls of the crucible.
