Description

Technical Field

[0001] The present invention relates to the technical field of bar conveying, and particularly to an automatic conveying device for a tungsten-aluminum alloy production line. Background Art

[0002] Aluminum alloy is an alloy material with unique physical and chemical properties, composed of two metal elements, tungsten and aluminum. Due to the extremely high hardness of tungsten-aluminum alloy, it is usually processed into various cutting tools, such as milling cutters, drill bits, etc. The processing process mainly includes cutting, pretreatment, rough machining, finish machining, edge treatment, etc. Among them, when cutting tungsten-aluminum alloy bars (hereinafter referred to as tungsten bars), a conveying mechanism is generally equipped. The conveying mechanism intermittently conveys the tungsten bars to the processing station, and then the cutting equipment cuts the tungsten bars to obtain tungsten bars of the required length.

[0003] The existing tungsten bar conveying mechanism is generally chain belt type. The driving component drives the chain belt to move horizontally, and then the chain belt drives the bearing platform on which the tungsten bars are placed to move horizontally to transport the tungsten bars to the processing station for cutting. The chain belt is generally driven by sprockets distributed at intervals. When the chain belt passes through the positions supported by sprockets and the positions not supported by sprockets, the supporting forces received are inconsistent, resulting in a certain shaking of the bearing platform on the chain belt. Moreover, the tungsten bars are not limited and fixed. In this way, the position stability and accuracy of the tungsten bars relative to the bearing platform will be affected. Subsequently, when the tungsten bars move to the processing station, the relative position accuracy between them and the cutting equipment will be affected, ultimately affecting the cutting quality of the tungsten bars and the uniformity and consistency of the tungsten bars cut in the same batch. Summary of the Invention

[0004] To solve the above problems, the present invention provides an automatic conveying device for a tungsten-aluminum alloy production line, including a frame and a chain plate conveyor installed on the frame. A number of bearing platforms are circumferentially and evenly installed on the chain plate conveyor. A centering and fixing mechanism is installed on the bearing platform. A locking mechanism for connecting and locking adjacent two bearing platforms is installed on the bearing platform. A guiding and limiting mechanism for guiding the movement of the bearing platform is installed on the frame.

[0005] The centering and fixing mechanism includes support plates fixedly installed at the top of the bearing platform and symmetrically arranged front and back. A V-shaped groove for supporting and limiting the tungsten bar is opened at the top of the support plate. A fixing component for pressing and fixing the tungsten bar is also installed on the support plate. A centering component for clamping the tungsten bar front and back is installed on the bearing platform.

[0006] The linkage mechanism includes a locking component and a connecting component respectively installed on the left and right sides of the bearing platform. Adjacent two bearing platforms are connected and cooperated through the locking component and the connecting component on their opposite sides to achieve locking.

The prism is rotatably installed on the bearing platform and its front end rotatably penetrates to the front of the bearing platform and is fixedly connected to a turning handle. The turning handle is connected and locked to the bearing platform through a bolt.

[0009] In a possible implementation manner, the fixing component includes movable blocks that are slidably installed up and down inside the support plate and are symmetric left and right. A pressing block is slidably installed left and right on the top of the movable block. One end of the pressing block close to the center of the support plate extends into the V-shaped groove. The support plate and the pressing block are slidably matched through a key groove parallel to the corresponding hypotenuse of the V-shaped groove. The bottom of the movable block is fixedly connected to an L-shaped pull rod with a horizontal section extending into the inside of the bearing platform. Oblique pull bars are symmetrically and fixedly connected to the left and right sides of the moving block. The vertical section of the L-shaped pull rod is slidably connected to the bearing platform. The oblique pull bar is composed of two horizontal sections and an inclined section that is connected between the horizontal sections and whose front end is inclined upward. The horizontal section of the L-shaped pull rod abuts against the bottom of the oblique pull bar. A first return spring is fixedly connected between the bottom of the movable block and the top of the bearing platform.

[0010] In a possible implementation manner, the connecting component includes fixed shells that are fixedly connected to the right side of the bearing platform and are symmetric front and back. A plug-in block is slidably installed along the length direction on one side of the fixed shell away from the center of the corresponding bearing platform. A pushing member for pushing the plug-in block to move away from the center of the bearing platform is installed on the fixed shell. A third return spring that is symmetric front and back with respect to the plug-in block is fixedly connected between one end of the plug-in block close to the center of the bearing platform and the inner wall of the fixed shell.

[0011] In a possible implementation manner, the pushing member includes a bidirectional screw rod that is rotatably installed on the fixed shell. The two bidirectional screw rods corresponding to the front and back are fixedly connected through a connecting rod. Wedge-shaped pushing blocks are threadedly connected to both thread sections with opposite thread directions of the bidirectional screw rod. The two wedge-shaped pushing blocks corresponding to the front and back are symmetrically distributed with respect to the corresponding plug-in block and their inclined surfaces are all slidably matched with the left end of the plug-in block. One end of the bidirectional screw rod away from the center of the frame is coaxially fixedly connected to a second gear located outside the fixed shell.

[0012] In a possible implementation manner, the locking component includes locking blocks that are fixedly connected to the left side of the bearing platform and are symmetric front and back. A slot for plugging and matching with the plug-in block is opened on the locking block. A locking rod for plugging and locking the plug-in block is slidably installed up and down inside the locking block. A docking groove for matching with the bottom end of the locking rod is opened on the bottom wall of the slot. An unlocking member for driving the locking rod to be unlocked is installed on the locking rod.

[0013] In a possible implementation manner, the unlocking member includes a wedge-shaped block fixedly connected after the top end of the locking rod slidably penetrates through the top of the locking block. A retaining piece is fixedly connected to the locking rod. An activity groove for the retaining piece to slide up and down is opened on the locking block. A fourth return spring sleeved on the outside of the locking rod is fixedly connected between the bottom of the retaining piece and the inner wall of the activity groove.

[0014] In a possible implementation manner, the driving component includes vertical plates fixedly connected to the tops of the front and rear vertical sections of the frame. On the left and right ends of the side of each vertical plate close to the center of the frame, a lower rack and an upper rack are respectively fixedly connected. The lower rack is meshed and cooperated with the lower side of the second gear, and the upper rack is meshed and cooperated with the upper side of the second gear. On the side of the vertical plate close to the center of the frame, a limiting groove for slidably cooperating with the end of the bidirectional screw is also provided. The tops of the front and rear vertical sections of the frame are both fixedly connected with pressing plates cooperating with the wedge-shaped blocks through L-shaped brackets. The pressing plates are located directly above the locking rods and the left ends thereof are inclined upward. The lower rack and the upper rack are respectively located on the left and right sides of the pressing plates.

[0015] In a possible implementation manner, the guiding and limiting mechanism includes guiding blocks fixedly connected to the bottom of the carrying platform and symmetrically arranged front and rear. Straight guiding grooves are fixedly connected to the inner sides of the front and rear vertical sections of the frame. The guiding blocks are slidably cooperated with the corresponding straight guiding grooves. A limiting plate is fixedly connected to the top of the straight guiding groove. An L-shaped limiting rod is also fixedly connected to the wedge-shaped pushing block on the side far from the center of the frame. The end of the L-shaped limiting rod far from the corresponding wedge-shaped pushing block slides through the outside of the fixed shell and abuts against the outer side of the limiting plate.

[0016] Advantages of the present invention: 1. Through the linkage cooperation of the support plate, the fixing component and the centering component, the tungsten rod placed on the support plate is centered, clamped and firmly fixed, preventing the tungsten rod from moving and shifting during transportation, enabling the tungsten rod to be accurately conveyed to the processing station, thereby facilitating the improvement of the accuracy of subsequent tungsten rod cutting processing. Moreover, the adjusting component can adjust the initial centering and clamping distance of the centering component, facilitating the centering and clamping of tungsten rods of different lengths by the centering component.

[0017] 2. Through the linkage cooperation of the connecting component, the locking component and the driving component, the adjacent two carrying platforms for transporting tungsten rods are locked, connecting several carrying platforms for transporting tungsten rods into a whole. Then, the guiding and limiting mechanism is used to guide and limit the movement of several carrying platforms connected into a whole, greatly improving the stability of the carrying platform when transporting tungsten rods, further improving the stability of the tungsten rod during movement, and further improving the accuracy when the tungsten rod is conveyed to the processing station for cutting processing.

[0018] 3. Through the mutual cooperation of the guiding block, the straight guiding groove, the limiting plate and the L-shaped limiting rod, the carrying platform is guided and limited. During the locking process of the connecting component and the locking component, the L-shaped limiting rod can be synchronously driven to clamp the outer side of the limiting plate before and after, realizing the front and rear limiting of the carrying platform. At the same time, the straight guiding groove is used to guide and limit the straight guiding groove, preventing the carrying platform from moving and shaking before and after and up and down when moving to the right, improving the stability of the carrying platform movement.

Detailed implementation mode

[0031] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation mode of the present invention in conjunction with the attached drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation mode disclosed below.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , a tungsten-aluminum alloy production line automatic conveying device, including a frame 1 and a chain plate conveyor 2 installed on the frame 1. A number of bearing platforms 3 are circumferentially and evenly installed on the chain plate conveyor 2. A centering and fixing mechanism 4 is installed on the bearing platform 3. An interlocking mechanism 5 for connecting and locking two adjacent bearing platforms 3 is installed on the bearing platform 3. A guiding and limiting mechanism 6 for moving and guiding the bearing platform 3 is installed on the frame 1. It should be noted that the chain plate conveyor 2 belongs to the prior art. The chain plate conveyor 2 drives the bearing platform 3 to perform intermittent circumferential movement in the clockwise direction, so that the upper bearing platform 3 can drive the tungsten rod to move intermittently from left to right. The cutting station is arranged at the right rear side of the conveying device, and the cutting method adopted by the existing cutting equipment at the cutting station can be selected adaptively.

[0033] Please refer to Figure 1 ,Figure 2 and Figure 4 The centering and fixing mechanism 4 includes support plates 41 fixedly installed symmetrically front and back on the top of the bearing table 3. A V-shaped groove for supporting and limiting the tungsten rod is formed on the top of the support plate 41. A fixing component 42 for pressing and fixing the tungsten rod is also installed on the support plate 41. A centering component 43 for centering and clamping the tungsten rod front and back is installed on the bearing table 3.

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The interlocking mechanism 5 includes a locking component 52 and a connecting component 51 respectively installed on the left and right sides of the bearing table 3. Adjacent two bearing tables 3 are connected and cooperated through the locking component 52 and the connecting component 51 on their opposite sides to achieve locking. A driving component 53 for driving the connecting component 51 and the locking component 52 between adjacent two bearing tables 3 to lock with each other is installed on the frame 1.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The centering component 43 includes centering clamping plates 431 slidably installed front and back on the top of the bearing table 3 and symmetrically distributed front and back. Limiting holes are formed on the opposite sides of the front and back two centering clamping plates 431. The centering clamping plates 431 are located outside the support plate 41. A centering component for driving the front and back two centering clamping plates 431 to move towards each other for centering and clamping is installed inside the bearing table 3. The centering component includes two moving blocks 432 slidably installed front and back inside the bearing table 3 and used to drive the corresponding centering clamping plates 431 to move back and forth. The two moving blocks 432 are symmetrically distributed front and back with respect to the bearing table 3. A first gear 433 is rotatably installed inside the bearing table 3. A first rack 434 is meshed with both the left and right sides of the first gear 433. The end of the first rack 434 away from the center of the bearing table 3 is fixedly connected to the corresponding moving block 432. A push rod 435 is fixedly connected to the bottom of the front moving block 432. A through groove for the push rod 435 to slide back and forth is formed at the bottom of the bearing table 3. A wedge-shaped guiding block 436 matched with the push rod 435 is fixedly connected to the inner side of the frame 1 through a cross beam. The inclined surface at the left end of the wedge-shaped guiding block 436 inclines backward. A stop block is fixedly installed in the middle of the bearing table 3 above the first gear 433. A second return spring 437 is fixedly connected between the front and back sides of the stop block and the corresponding moving block 432.

[0036] Please refer to Figures 1-6When the tungsten rod is to be transported, when the carrier 3 stops moving intermittently, the tungsten rod is placed on the V-grooves on the top of the two corresponding support plates 41 on the leftmost side and in a horizontal state, and then the chain plate conveyor 2 drives the upper carrier 3 to move intermittently from left to right. When the push rod 435 moves to contact the inclined surface at the left end of the wedge-shaped guide block 436 and continues to move, the inclined surface is used to push the push rod 435 to move backward. At this time, the push rod 435 will drive the front moving block 432 to move backward, and the front moving block 432 will drive the right rack 434 to move backward. The right rack 434 drives the left rack 434 through the transmission of the gear 433. The rack 434 on the side moves forward, thereby pushing the moving block 432 on the rear side to move forward. At this time, the reset spring 437 will be compressed, and the moving blocks 432 on the front and rear sides drive the corresponding centering clamps 431 to move toward each other, and the tungsten rod is clamped front and back. The end of the tungsten rod is inserted into the limiting hole, and the limiting hole limits the tungsten rod to ensure that the cutting point position at the end of the tungsten rod is accurately aligned with the working end of the cutting equipment on the cutting station, and also ensures that the rear end faces of several tungsten rods to be cut in the same batch are on the same vertical plane, thereby ensuring the consistency of cutting of several tungsten rods to be cut in the same batch, improving the cutting quality and the uniformity of cutting.

[0037] When the push rod 435 leaves the inclined surface at the left end of the wedge-shaped guide block 436, it continues to contact the rear end surface of the wedge-shaped guide block 436. Under the limit of the rear end surface of the wedge-shaped guide block 436, the centering clamping plate 431 maintains the centering clamping state of the tungsten rod. When the support platform 3 moves to the right side of the wedge-shaped guide block 436, the push rod 435 is no longer limited by the wedge-shaped guide block 436. At this time, the rebound force of the reset spring 437 is used to push the moving blocks 432 on the front and rear sides away from each other, so that the centering clamping plate 431 releases the clamping of the tungsten rod, and the front moving block 432 drives the push rod 435 to move forward and reset, so as to quickly remove the processed tungsten rod.

[0038] See also Figure 4 , Figure 5 and Figure 6 , an adjusting component 44 for adjusting the initial spacing between the front and rear centering plates 431 is also installed on the moving block 432, and the adjusting component 44 includes a threaded rod 441 rotatably installed inside the moving block 432, and the two threaded rods 441 in the same bearing platform 3 have opposite thread directions, and the external thread of the threaded rod 441 is connected to the adjusting block 442, and the adjusting block 442 is slidably installed inside the corresponding moving block 432, and the centering plate 431 is fixedly installed on the top of the corresponding adjusting block 442, and a prism 443 is slidably installed between the front and rear threaded rods 441, and the prism 443 is rotatably installed on the bearing platform 3 and its front end rotates through the front of the bearing platform 3 and is fixedly connected to a turning handle 444, and the turning handle 444 is connected and locked to the bearing platform 3 by bolts.

[0039] When adjusting the initial distance between the front and rear centering clamping plates 431, first loosen the bolt fixing the rotary handle 444, then rotate the rotary handle 444 to drive the prism 443 to rotate, and then the prism 443 drives the front and rear threaded rods 441 to rotate simultaneously. Then, the threaded rods 441 drive the corresponding adjusting blocks 442 to move. Since the thread directions on the front and rear threaded rods 441 are opposite, the front and rear adjusting blocks 442 will move synchronously in opposite directions. Then, the adjusting blocks 442 drive the corresponding centering clamping plates 431 to move, completing the adjustment of the initial distance between the front and rear centering clamping plates 431, which is convenient for centering and clamping tungsten rods of different lengths. It should be noted that the cutting point of the tungsten rod is always set at its rear end, that is, the cutting point is located between the rear centering clamping plate 431 and its adjacent support plate 41. The chain conveyor 2 conveys several tungsten rods of the same length at the same time, and the diameters of tungsten rods of different lengths are the same.

[0040] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 Figure, the fixing assembly 42 includes movable blocks 421 that are symmetrically installed left and right and slide up and down inside the support plate 41. A pressing block 422 is slidably installed left and right on the top of the movable block 421. One end of the pressing block 422 close to the center of the support plate 41 extends into the V-shaped groove. The support plate 41 and the pressing block 422 are slidably matched through a key groove parallel to the corresponding hypotenuse of the V-shaped groove. The bottom of the movable block 421 is fixedly connected to an L-shaped pull rod 423 whose horizontal section extends into the carrier 3. Diagonal stay bars 424 are symmetrically and fixedly connected to the left and right sides of the moving block 432. The vertical section of the L-shaped pull rod 423 is slidably connected to the carrier 3. The diagonal stay bar 424 is composed of two horizontal sections and an inclined section connecting the horizontal sections with the front end inclined upward. The horizontal section of the L-shaped pull rod 423 abuts against the bottom of the diagonal stay bar 424. A first return spring 425 is fixedly connected between the bottom of the movable block 421 and the top of the carrier 3.

[0041] When the front and rear centering clamping plates 431 center and clamp the tungsten rod, the two moving blocks 432 moving towards each other will drive the corresponding diagonal stay bars 424 to move synchronously. During the inward movement of the diagonal stay bar 424, the lower inclined surface of its inclined section will push the horizontal section of the L-shaped pull rod 423 downward. The L-shaped pull rod 423 then drives the movable block 421 and the pressing block 422 to move downward. The first return spring 425 is compressed and contracted. The pressing block 422 moves downward along with the movable block 421 under the guidance of the key groove and moves towards the center of the V-shaped groove. Finally, the pressing block 422 presses against the top of the tungsten rod, and the tungsten rod is limited in the V-shaped groove, preventing the tungsten rod from shifting during transportation, improving the stability of tungsten rod transportation, and ensuring the unity of the positioning of several tungsten rods of the same batch.

[0042] When the chain plate conveyor 2 pauses moving when transporting the tungsten rod to the cutting station, the rear cutting point of the tungsten rod is then cut by the cutting equipment. The centering clamping plate 431 at the rear side and its adjacent support plate 41 cooperate to support, fix and limit the front and rear positions of the cutting point of the tungsten rod during the cutting process, effectively improving the cutting quality of the tungsten rod. After cutting, the chain plate conveyor 2 drives the tungsten rod to continue moving to the right.

[0043] When the front and rear centering clamping plates 431 loosen the clamping of the tungsten rod, the two moving blocks 432 moving away from each other will drive the corresponding diagonal tension bars 424 to move outwards. At this time, the diagonal tension bars 424 no longer push the L-shaped pull rod 423, and the resilience of the first reset spring 425 is used to push the movable block 421 and the pressing block 422 upwards, so that the pressing block 422 releases the pressing lock on the tungsten rod, facilitating the taking of the tungsten rod.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 8 As shown in, the connecting component 51 includes fixed shells 511 that are fixedly connected to the right side of the carrying platform 3 and are symmetrically arranged front and rear. A plug-in block 512 is slidably installed on one side of the fixed shell 511 away from the center of the corresponding carrying platform 3 along its length direction. A pushing component 513 for pushing the plug-in block 512 to move away from the center of the carrying platform 3 is installed on the fixed shell 511. A third reset spring 514 that is symmetrically arranged front and rear with respect to the plug-in block 512 is fixedly connected between one end of the plug-in block 512 close to the center of the carrying platform 3 and the inner wall of the fixed shell 511.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 8 As shown in, the pushing component 513 includes a bidirectional screw 5131 rotatably installed on the fixed shell 511. The two bidirectional screws 5131 corresponding to the front and rear are fixedly connected by a connecting rod. Wedge-shaped pushing blocks 5132 are threadedly connected to both thread sections with opposite helix directions of the bidirectional screw 5131. The front and rear two wedge-shaped pushing blocks 5132 are symmetrically distributed front and rear with respect to the corresponding plug-in block 512 and the inclined surfaces are all slidably matched with the left end of the plug-in block 512. One end of the bidirectional screw 5131 away from the center of the frame 1 is coaxially fixedly connected with a second gear 5133 located outside the fixed shell 511.

[0046] When the second gear 5133 moves from left to right to the left end of the drive assembly 53, the drive assembly 53 is used to drive the second gear 5133 to rotate. The second gear 5133 drives the bidirectional screw 5131 to rotate, and the bidirectional screw 5131 drives the corresponding two wedge-shaped pushing blocks 5132 to move towards each other. The inclined surface of the wedge-shaped pushing block 5132 is used to push the insertion block 512 to move to the right. At this time, the third return spring 514 will be compressed, so that the right end of the insertion block 512 extends to the right and is inserted and matched with the corresponding locking assembly 52.

[0047] When the second gear 5133 moves from left to right to the right end of the drive assembly 53, the drive assembly 53 is used again to drive the second gear 5133 to rotate in the reverse direction. The second gear 5133 drives the bidirectional screw 5131 to rotate in the reverse direction, so that the corresponding two wedge-shaped pushing blocks 5132 move in the reverse direction. At this time, the resilience of the third return spring 514 is used to push the insertion block 512 to move to the left, so that the insertion block 512 is separated from the locking assembly 52.

[0048] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 10 , the locking assembly 52 includes locking blocks 521 that are fixedly connected to the left side of the bearing table 3 and are symmetrically arranged front and back. A slot 522 that is inserted and matched with the insertion block 512 is provided on the locking block 521. A locking rod 523 for inserting and locking the insertion block 512 is slidably installed up and down inside the locking block 521. A docking groove that cooperates with the bottom end of the locking rod 523 is provided on the bottom wall of the slot 522. An unlocking component 524 for driving the locking rod 523 to unlock is installed on the locking rod 523.

[0049] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 10 , the unlocking component 524 includes a wedge-shaped block 5241 fixedly connected after the top end of the locking rod 523 slidably penetrates the top of the locking block 521. A retaining piece 5242 is fixedly connected to the locking rod 523. A movable groove for the retaining piece 5242 to slide up and down is provided on the locking block 521. A fourth return spring 5243 sleeved outside the locking rod 523 is fixedly connected between the bottom of the retaining piece 5242 and the inner wall of the movable groove.

[0050] In the initial state, the baffle 5242 is located at the top of the movable slot, and the bottom of the locking rod 523 is not inserted into the slot 522. After the right end of the plug-in block 512 is inserted into the slot 522, the driving assembly 53 is used to drive the wedge block 5241 and the locking rod 523 to move downward, so that the bottom end of the locking rod 523 is inserted into the plug-in block 512 and is inserted into the docking groove, thereby connecting and locking the plug-in block 512 with the locking block 521, and further realizing the connection and locking between two adjacent carrier platforms 3, improving the stability when the upper carrier platform 3 conveys tungsten rods.

[0051] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 , the driving assembly 53 includes vertical plates 531 fixedly connected to the tops of the front and rear vertical sections of the frame 1. The left and right ends of the vertical plate 531 close to the center of the frame 1 are respectively fixedly connected with a lower rack 532 and an upper rack 533. The lower rack 532 is meshed with the lower side of the second gear 5133, and the upper rack 533 is meshed with the upper side of the second gear 5133. A limiting groove 534 for slidably fitting with the end of the bidirectional screw 5131 is also formed on the side of the vertical plate 531 close to the center of the frame 1. The tops of the front and rear vertical sections of the frame 1 are both fixedly connected with pressing plates 535 that cooperate with the wedge block 5241 through L-shaped brackets. The pressing plate 535 is located directly above the locking rod 523 and the left end is inclined upward. The lower rack 532 and the upper rack 533 are respectively located on the left and right sides of the pressing plate 535.

[0052] When the carrier platform 3 moves to the left end of the vertical plate 531, the end of the bidirectional screw 5131 will enter the limiting groove 534. The limiting groove 534 is used to guide and support the bidirectional screw 5131, improving the smoothness of the movement of the bidirectional screw 5131 and the second gear 5133. At the same time, the lower side of the second gear 5133 will be meshed with the lower rack 532, and the lower rack 532 is used to drive the second gear 5133 and the bidirectional screw 5131 to rotate clockwise, thereby driving the plug-in block 512 to extend to the right and be inserted into the slot 522 for mating.

[0053] As the carrier platform 3 continues to move to the right, the left end of the pressing plate 535 slides and fits with the inclined surface of the wedge block 5241. The left end of the pressing plate 535 will push the wedge block 5241 and the locking rod 523 to move downward to insert and lock the plug-in block 512. After that, during the horizontal rightward movement of the carrier platform 3, the horizontal lower end surface of the pressing plate 535 will always press the wedge block 5241, so that the locking rod 523 keeps locking the plug-in block 512.

[0054] When the carrier table 3 moves to the right end of the extrusion plate 535, the wedge block 5241 separates from the extrusion plate 535. After losing the pressing of the extrusion plate 535, the locking rod 523 moves upward to reset under the resilience of the fourth return spring 5243, realizing the unlocking of the plug-in block 512.

[0055] After that, the carrier table 3 moves to the right end of the vertical plate 531. At this time, the upper rack 533 meshes with the top of the second gear 5133 and drives the second gear 5133 to rotate counterclockwise, so that the two wedge-shaped pushing blocks 5132 move in opposite directions, and the plug-in block 512 moves leftward under the resilience of the third return spring 514 and separates from the slot 522, releasing the locking between adjacent carrier tables 3.

[0056] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 8 and Figure 11 As shown in

[0057] When the carrier table 3 moves to the left end of the straight guide groove 62, the guide block 61 will enter the straight guide groove 62. The straight guide groove 62 is used to guide and limit the guide block 61 to prevent the carrier table 3 from shaking up and down and back and forth, improving the stability of the carrier table 3 for transporting tungsten rods. When the wedge-shaped pushing blocks 5132 move towards each other, the wedge-shaped pushing block 5132 on the side away from the center of the frame 1 will drive the L-shaped limit rod 64 to move together, so that the two corresponding front and rear L-shaped limit rods 64 move towards each other. The vertical section of the L-shaped limit rod 64 will abut against the outside of the limit plate 63. The limit plate 63 is used to guide and limit the L-shaped limit rod 64, further improving the stability of the carrier table 3 for transporting tungsten rods, and at the same time facilitating further improving the structural strength of the bidirectional screw 5131.
