Description

Technical Field

[0001] The invention relates to the technical field of clamping tooling, and in particular to a clamping device for an automobile cooling pipe assembly. Background Art

[0002] The automotive cooling pipe assembly is generally composed of multiple cooling pipes connected together. The cooling pipe is generally made by bending a straight metal raw pipe. In order to avoid the hidden space formed by the bending of the metal raw pipe, which will cause obstruction and interference to the grinding and polishing action, the metal raw pipe is generally ground and polished before it is bent. When grinding and polishing the metal raw pipe, a device for clamping and positioning the metal raw pipe is required.

[0003] In order to facilitate the insertion, pulling, loading and unloading of pipe fittings, some existing clamping tools often set the clamping parts that specifically implement the clamping action to be in the form of a swingable empty position. When disassembling and unloading the pipe fittings, it is necessary to first slide the clamping parts away from the pipe fittings to loosen the pipe fittings, and then swing the clamping parts to the empty position. When inserting and loading the pipe fittings, it is necessary to first swing the clamping parts back to the clamping use state, and then drive the clamping parts to clamp on the pipe fittings. In this way, when loading and unloading the pipe fittings, two steps need to be performed in sequence, which is troublesome and inconvenient to operate, which reduces the loading and unloading efficiency of the pipe fittings, and indirectly reduces the processing efficiency of grinding and polishing the pipe fittings using the clamping tooling. Summary of the invention

[0004] In view of this, the present invention provides a clamping device for an automobile cooling pipe assembly to solve the problem that when loading and unloading pipes, two operations need to be performed in sequence, which is troublesome and inconvenient to operate.

[0005] The technical solution proposed by the present invention is: a clamping device for an automobile cooling pipe assembly, specifically comprising: a processing platform, wherein two vertical support plates are symmetrically welded at the middle position in the width direction of the processing platform;

[0006] Two L-shaped rail rods are symmetrically welded to the bottom end of the two vertical support plates; two vertical support slide plates are symmetrically slidably installed on the two L-shaped rail rods; a group of vertical strip plates are welded to the top of the two vertical support slide plates, and two L-shaped swing rods rotating in opposite directions are installed on the top of the two groups of vertical strip plates; a clamping wheel is rotatably installed at the head end of the long rod section of the L-shaped swing rod, and the two clamping wheels are used to clamp and fix the raw material pipe to be polished;

[0007] Two U-shaped positioning frames are symmetrically welded on the upper half of the two vertical support plates, and a poking rod is welded on the vertical side axis of the U-shaped positioning frame; a driving slider is slidably installed on the U-shaped positioning frame through a spring; a pull rod is rotatably connected between the driving slider and the head end of the short rod section of the L-shaped swing rod; the bottom ends of the two groups of vertical strip plates are welded with longitudinal support blocks, and the driving slider is in contact with the longitudinal support block;

[0008] When the two vertical support slides slide away from each other, the two poking rods pass through the two longitudinal support blocks and come into contact with the two driving slides; a guide plate is welded on both sides of each vertical support plate above the top of the processing platform, and the guide plates are symmetrically welded, and the guide plates are arranged horizontally as a whole and have an inclined and bent structure at the tail end; two rectangular positioning frames are symmetrically welded on the bottom parts of the two groups of vertical strip plates, and the rectangular positioning frames are located on opposite sides of the longitudinal support blocks, and two plug shafts spaced apart from each other are installed in the rectangular positioning frames through the spring pushing and sliding installation; when the two vertical support slides slide close to each other, the tail end of the plug shaft comes into contact with the inclined and bent part of the guide plate, and when the plug shaft is driven to slide inward, the head end is plugged into and matched with the driving slide.

[0009] Furthermore, the two vertical support plates are located at adjacent positions on the upper side of the L-shaped track rod, and a threaded rocker is rotatably installed through the two vertical support plates. The two ends of the threaded rocker are provided with two sections of external threads arranged in opposite directions. The positive and negative thread sections of the threaded rocker are correspondingly screwed through the two vertical support slide plates.

[0010] The tail ends of the two L-shaped track rods are respectively welded and fixed to the middle positions of the two short sides of the processing platform.

[0011] Furthermore, the poking rod is parallel to the upper and lower side axes of the U-shaped positioning frame and is located inside the U-shaped positioning frame.

[0012] Furthermore, four insertion holes are symmetrically provided on the head end of the driving slider, and the head end of the insertion shaft is plugged into and matched with the insertion holes.

[0013] Furthermore, each group of the vertical strip plates includes two vertical strip plates that are spaced apart, and a spacing groove is formed between the two vertical strip plates that are arranged in a group, and the driving slider is slidably plugged into the spacing groove.

[0014] Furthermore, a U-shaped positioning frame is welded between the upper parts of the two vertical support plates, a shaft sleeve is slidably mounted on the vertical support shaft of the U-shaped positioning frame, a U-shaped mounting frame is welded on the shaft sleeve, and an insertion rod is slidably installed inside the U-shaped mounting frame through a spring push.

[0015] Further, two symmetrically arranged vertical sliding plates are slidably mounted on the two horizontal support shafts of the T-shaped positioning frame. Positioning rings are welded to the tops of the two vertical sliding plates, and the raw material pipe to be polished is rotatably fitted through the two positioning rings.

[0016] Further, two connecting rods are symmetrically and rotatably connected between the top parts of the two vertical sliding plates and the bushings.

[0017] Further, two positioning holes are vertically spaced apart on the vertical support shaft of the T-shaped positioning frame, and the first end part of the insertion rod passes through the bushing and is inserted and fitted with the positioning hole.

[0018] Further, a motor is threadedly fastened to the long rod section of one of the L-shaped swing rods, and the motor is axially connected and driven with the corresponding clamping wheel.

[0019] A clamping device for an automobile cooling pipe assembly provided by the present invention has the following beneficial effects:

[0020] In the present invention, only by performing the operation of driving the two vertical support sliding plates to slide towards each other, the sliding tightening and loosening actions of the two clamping wheels and the raw material pipe can be driven to be completed at one time, as well as the swing empty position and the swing vertical return position actions of the two clamping wheels, so as to load and unload the raw material pipe. Compared with the prior art, the trouble of having to perform the above two corresponding actions sequentially to load and unload the raw material pipe is saved, and the operation and use are more convenient, which helps to improve the loading and unloading efficiency of the raw material pipe and the processing efficiency of polishing the raw material pipe using this clamping tooling.

[0021] In addition, when the two L-shaped swing rods and the two clamping wheels are kept in the vertical clamping state, they can continue to approach and slide relative to each other to adjust the clamping distance, which is suitable for clamping raw material pipes of different lengths, and helps to expand the compatibility of the device with raw material pipes of different lengths.

[0022] In addition, through the inclined plane guiding principle of the inclined parts of the four guiding plates, when the two vertical support sliding plates and the clamping wheels approach and slide relative to each other to clamp the raw material pipe, the eight insertion shafts can be simultaneously pushed inwards to perform plugging and positioning on the two driving sliders. And during the process of the two vertical support sliding plates and the two clamping wheels moving away from each other to loosen the raw material pipe, when the eight insertion shafts are separated from the four guiding plates, the eight insertion shafts can be automatically pushed outwards by the springs thereon, so as to pull out and loosen the two driving sliders. This can save the trouble of manually exerting extra force to insert and extract the eight insertion shafts, and helps to simplify the tightening and loosening operations and the loading and unloading operation steps of the raw material pipe.

[0023] In addition, the straight plate sections of the four guide plates are used to push the eight plug-in shafts to maintain them in an internally sliding and plug-in state, and the straight plate sections of the four guide plates have a considerable length. The eight plug-in shafts slide left and right following the two L-shaped swing rods and two clamping wheels in the vertical clamping state. When adjusting the clamping spacing, their tail ends can slide left and right along the straight plate sections of the four guide plates, and continuously plug and position the two L-shaped swing rods and the two clamping wheels, and continuously maintain the two L-shaped swing rods and the two clamping wheels in the vertical clamping state, so that the two clamping wheels can clamp raw material pipes of different lengths. Therefore, the straight plate sections of the four guide plates with considerable length can ensure the normal and effective implementation of the device compatibility function.

[0024] In addition, the two vertical sliding plates and the two positioning rings are installed for sliding movement, and the two connecting rods, the two vertical sliding plates and the sleeves are connected together to form two crank slider mechanisms. Through these two mechanisms, the sleeves can slide downward to push and drive the vertical sliding plates and the two positioning rings to slide towards each other, leaving the position on the raw material pipe surrounded and shielded by the two positioning rings for grinding. This is conducive to comprehensive and thorough grinding of the raw material pipe. Compared with the traditional device in which the two positioning rings are fixed statically, it can avoid the occurrence of grinding dead corners and missed grinding.

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0045] For convenience of description, the length direction of the processing platform 1 is marked as the left-right direction, and the width direction is marked as the front-back direction;

[0046] Please refer to Figures 1 to 9 ; Embodiment 1:

[0047] The present invention proposes a clamping device for an automobile cooling pipe assembly, comprising: a processing platform 1, a vertical support plate 101, a U-shaped positioning frame 102, a shaft sleeve 1021, a U-shaped mounting frame 1022, an insertion rod 1023, an L-shaped track rod 103, a U-shaped positioning frame 104, a poking rod 1041, a driving slider 1042, a guide plate 105, a threaded rocker 2, a vertical sliding plate 3, a positioning ring 301, a connecting rod 302, a vertical support slide plate 4, a vertical strip plate 401, a longitudinal support block 402, a rectangular positioning frame 403, an insertion shaft 4031, an L-shaped swing rod 5, a clamping wheel 501, a pull rod 502, and a motor 6. Two vertical support plates 101 are symmetrically welded at the middle position in the width direction of the processing platform 1;

[0048] Among them, two L-shaped track rods 103 are symmetrically welded to the bottom parts of the two vertical support plates 101; two vertical support slide plates 4 are symmetrically slidably installed on the two L-shaped track rods 103; a group of vertical strip plates 401 are welded to the top of the two vertical support slide plates 4, and two L-shaped swing rods 5 rotating in opposite directions are installed on the top of the two groups of vertical strip plates 401; a clamping wheel 501 is rotatably installed at the head end of the long rod section of the L-shaped swing rod 5; a motor 6 is threadedly fastened on the long rod section of one L-shaped swing rod 5, and the motor 6 is axially connected to the clamping wheel 501 at the corresponding position for transmission; positioning rings 301 are welded to the tops of the two vertical sliding plates 3, and the raw material pipe to be ground and processed penetrates and rotates with the two positioning rings 301;

[0049] When the two L-shaped swinging rods 5 are swung upward and erected, the two clamping wheels 501 are aligned with the two positioning rings 301 and are located on the same axis. The two positioning rings 301 are used to insert the raw material tube, and the raw material tube rotates in the two positioning rings 301. The two positioning rings 301 can ensure that the raw material tube is concentrically aligned with the two clamping wheels 501, and avoid eccentric misalignment between the two clamping wheels 501 and the raw material tube, which causes the raw material tube to be unable to rotate around the center of the two clamping wheels 501, resulting in up and down vibration, causing excessive wear on its body, the two clamping wheels 501 and the two positioning rings 301;

[0050] The two L-shaped swinging rods 5 and the two clamping wheels 501 are used to clamp and fix the raw material pipe to be polished when they are placed in a swinging upright state. After the two clamping wheels 501 clamp and position the raw material pipe, the raw material pipe can be connected to the motor 6 for transmission. The motor 6 is used to rotate and drive the raw material pipe to perform circumferential polishing on the surface of the raw material pipe. When the two L-shaped swinging rods 5 and the two clamping wheels 501 are placed in a swinging horizontal state, the space on the left and right sides of the raw material pipe can be vacated, which is convenient for the insertion and removal of the raw material pipe in the two positioning rings 301.

[0051] Two U-shaped positioning frames 104 are symmetrically welded to the upper half of the two vertical support plates 101, and a poking rod 1041 is welded on the vertical side axis of the U-shaped positioning frame 104; a driving slider 1042 is slidably installed on the U-shaped positioning frame 104 through a spring; a pull rod 502 is rotatably connected between the driving slider 1042 and the head end of the short rod section of the L-shaped swing rod 5; the bottom end portions of the two groups of vertical strip plates 401 are welded with longitudinal support blocks 402, and the driving slider 1042 is in contact with the longitudinal support block 402;

[0052] The two pull rods 502, the two driving sliders 1042 and the two L-shaped swinging rods 5 are connected together to form two crank rocker mechanisms. Through these two mechanisms, the two driving sliders 1042 can push and drive the two L-shaped swinging rods 5 to swing up and down, and control the two L-shaped swinging rods 5 and the two clamping wheels 501 to switch freely between the vertical clamping state and the horizontal empty state.

[0053] When the two vertical support slide plates 4 slide away from each other, the two poking rods 1041 pass through the two longitudinal support blocks 402 and come into contact with the two driving slide blocks 1042; a guide plate 105 is welded on both sides of each vertical support plate 101 above the top of the processing platform 1, and the guide plates 105 are symmetrically welded, and the guide plates 105 are arranged horizontally as a whole, and the tail ends are inclined and bent; two rectangular positioning frames 403 are symmetrically welded on the bottom parts of the two groups of vertical strip plates 401, and the rectangular positioning frames 403 are located on the opposite sides of the longitudinal support blocks 402, and two upper and lower spaced plug shafts 403 are installed in the rectangular positioning frames 403 through the spring push and slide. 1; when the two vertical support slide plates 4 slide close to each other, the tail end of the plug shaft 4031 comes into contact with the inclined bending part of the guide plate 105, and the head end of the plug shaft 4031 is plugged and matched with the driving slider 1042 when it is driven to slide inward; the two vertical support plates 101 are located at the adjacent positions on the upper side of the L-shaped track rod 103, and the threaded rocker 2 is rotatably installed through and through, and the head and tail ends of the threaded rocker 2 are provided with two sections of external threads arranged in counter-rotation directions, and the positive and negative thread sections of the threaded rocker 2 are correspondingly screwed through and through the two vertical support slide plates 4; the tail ends of the two L-shaped track rods 103 are respectively welded and fixed to the middle positions of the two short sides of the processing platform 1;

[0054] The threaded rocker 2 can rotate forward and reverse to drive the two vertical support slides 4 and the two clamping wheels 501 to slide towards each other to tighten or loosen the raw material tube; when the two vertical support slides 4 and the clamping wheels 501 slide away from each other to loosen the raw material tube, the two poking rods 1041 pass through the two longitudinal support blocks 402 and come into contact with the two driving slide blocks 1042, and can push and drive the two driving slide blocks 1042 to slide towards each other, thereby driving and controlling the two L-shaped swing rods 5 and the two clamping wheels 501 to swing to a horizontal empty state. , and then through the power transmission of the two poking rods 1041, when the two vertical support slide plates 4 slide away from each other to loosen the raw material tube, they can also push and drive the two L-shaped swing rods 5 and the two clamping wheels 501 to swing to an empty position, eliminating the trouble of additional manual effort to swing the two L-shaped swing rods 5 and the two clamping wheels 501 to an empty position, so that when the raw material tube is loosened, the separation and loosening action of the two clamping wheels 501 and the raw material tube and the swinging action of the two clamping wheels 501 to an empty position can be implemented in one operation;

[0055] When the two vertical support slide plates 4 and the clamping wheels 501 slide towards each other to clamp the raw material tube, after the two driving slide blocks 1042 are separated from the two poking rods 1041, the springs on the two U-shaped positioning frames 104 can automatically rebound and push to drive the two driving slide blocks 1042 to slide away from each other and return to rest against the two longitudinal support blocks 402, driving and controlling the two L-shaped swinging rods 5 and the two clamping wheels 501 to swing and reset to the vertical clamping state. This saves the trouble of manually swinging and returning the two L-shaped swinging rods 5 and the two clamping wheels 501 to the vertical position, so that when clamping the raw material tube, the vertical swinging and returning action of the two clamping wheels 501 and the sliding clamping action of the two clamping wheels 501 and the raw material tube can be implemented in one operation.

[0056] The present invention only needs to drive the two vertical support slide plates 4 to slide in the opposite direction, and can drive the two clamping wheels 501 and the raw material pipe to slide and tighten at one time, and the two clamping wheels 501 to swing to an idle position and swing to an upright position to return to the original position, so as to load and unload the raw material pipe. Compared with the prior art, the present invention saves the trouble of sequentially performing the above two corresponding actions to load and unload the raw material pipe, and is more convenient to operate and use, which helps to improve the efficiency of loading and unloading the raw material pipe and the processing efficiency of grinding and polishing the raw material pipe using the clamping tooling;

[0057] In the process of the two vertical support slide plates 4 and the clamping wheels 501 sliding close to each other to clamp the raw material pipe, when the two L-shaped swing rods 5 and the two clamping wheels 501 return to the upright clamping state, the eight plug-in shafts 4031 can respectively plug and position the two driving slide blocks 1042 with the four rectangular positioning frames 403, so that the two L-shaped swing rods 5 and the two clamping wheels 501 are kept in the upright clamping state to implement top pressure clamping on the raw material pipe; when the two L-shaped swing rods 5 and the two clamping wheels 501 are kept in the upright clamping state, they can continue to slide close to each other to adjust the clamping distance, which is suitable for clamping raw material pipes of different lengths, and helps to expand the compatibility of the device with raw material pipes of different lengths;

[0058] By the inclined guiding principle of the inclined parts of the four guide plates 105, when the two vertical support slide plates 4 and the clamping wheel 501 slide close to each other to clamp the raw material tube, the eight plug shafts 4031 can be pushed and driven to slide synchronously inwards, and the two driving slide blocks 1042 are plugged and positioned, and in the process of the two vertical support slide plates 4 and the two clamping wheels 501 sliding away from each other to loosen the raw material tube, when the eight plug shafts 4031 are separated from the four guide plates 105, the eight plug shafts 4031 can be automatically rebounded and pushed outwards by the springs thereon, and the two driving slide blocks 1042 are pulled out and loosened, which saves the trouble of additional manual effort to pull and tighten the eight plug shafts 4031, and helps to simplify the tightening and unloading operation steps of the raw material tube; after the two driving slide blocks 1042 are loosened, they can be pushed by the two poking rods 1041 to implement swing drive for the two L-shaped swing rods 5 and the two clamping wheels 501;

[0059] The straight plate sections of the four guide plates 105 are used to push the eight plug-in shafts 4031 and keep them in the inner sliding plug-in state, and the straight plate sections of the four guide plates 105 have a considerable length. The eight plug-in shafts 4031 slide left and right following the two L-shaped swing rods 5 and the two clamping wheels 501 in the vertical clamping state. When adjusting the clamping interval, the tail ends thereof can slide left and right along the straight plate sections of the four guide plates 105, and continuously plug and position the two L-shaped swing rods 5 and the two clamping wheels 501, and continuously keep the two L-shaped swing rods 5 and the two clamping wheels 501 in the vertical clamping state, so that the two clamping wheels 501 can clamp raw material pipes of different lengths. Therefore, the straight plate sections of the four guide plates 105 with considerable length can ensure the normal and effective implementation of the device compatibility function.

[0060] It is worth noting that: only when the driving slider 1042 is disengaged from the poking rod 1041, the spring on the U-shaped positioning frame 104 can push the driving slider 1042 back to abut against the longitudinal support block 402, and drive the L-shaped swing rod 5 and the clamping wheel 501 to the upright clamping state, and only when the driving slider 1042 is returned to abut against the longitudinal support block 402 (initial state) can the plug shaft 4031 be plugged and matched with it; there is a distance between the tail end of the guide plate 105 and the head end of the poking rod 1041, and the driving slider 1042 and the poking rod 1041 are kept apart. After the two L-shaped swing rods 5 and the two clamping wheels 501 are disengaged, the rear end of the plug-in shaft 4031 abuts against the inclined part of the guide plate 105, which can ensure that the two L-shaped swing rods 5 and the two clamping wheels 501 return to the upright clamping state. When the driving slider 1042 returns and abuts against the longitudinal support block 402, the plug-in shaft 4031 is plugged and matched with the driving slider 1042, so as to avoid the driving slider 1042 not fully returning and the plug-in shaft 4031 sliding inwards too early and being broken by the driving slider 1042, which can fail to effectively implement the upright positioning of the two L-shaped swing rods 5 and the two clamping wheels 501.

[0061] Preferably, the poking rod 1041 is parallel to the upper and lower side axes of the U-shaped positioning frame 104 and is located inside the U-shaped positioning frame 104 .

[0062] Preferably, four insertion holes are symmetrically provided on the front end portion of the driving slider 1042, and the front end of the insertion shaft 4031 is plugged into the insertion holes; each group of vertical strip plates 401 includes two vertical strip plates 401 spaced apart, and a spacing groove is formed between the two vertical strip plates 401 arranged in a group, and the driving slider 1042 is slidably plugged into the spacing groove.

[0063] Preferably, a motor 6 is threadedly fastened on the long rod section of an L-shaped swing rod 5, and the motor 6 is axially connected to a clamping wheel 501 at a corresponding position for transmission.

[0064] Based on the first embodiment, the second embodiment:

[0065] A U-shaped positioning frame 102 is welded between the upper halves of the two vertical support plates 101, and a shaft sleeve 1021 is slidably mounted on the vertical support shaft of the U-shaped positioning frame 102, and a U-shaped mounting frame 1022 is welded on the shaft sleeve 1021, and a plug rod 1023 is slidably installed inside the U-shaped mounting frame 1022 through a spring push; two symmetrical vertical sliding plates 3 are slidably mounted on the two horizontal support shafts of the U-shaped positioning frame 102.

[0066] Preferably, two connecting rods 302 are symmetrically connected to the top ends of the two vertical sliding plates 3 and the shaft sleeves 1021 for rotation; the vertical support shaft of the earth-shaped positioning frame 102 is provided with two positioning holes at intervals from top to bottom, and the head end of the insertion rod 1023 passes through the shaft sleeves 1021 and is plugged into the positioning holes;

[0067] The two vertical sliding plates 3 and the two positioning rings 301 are installed for sliding movement. The two connecting rods 302, the two vertical sliding plates 3 and the sleeves 1021 are connected together to form two crank slider mechanisms. Through these two mechanisms, the downward sliding sleeves 1021 can push and drive the vertical sliding plates 3 and the two positioning rings 301 to slide close to each other, leaving the positions on the raw material pipe surrounded and shielded by the two positioning rings 301 for grinding. This is conducive to comprehensive and thorough grinding of the raw material pipe. Compared with the traditional device in which the two positioning rings 301 are fixed and set statically, it can avoid the occurrence of grinding dead corners and missed grinding. The insertion rod 1023 is selected to be plugged into and matched with the two positioning holes to plug and fix the sleeves 1021, so that the two vertical sliding plates 3 and the two positioning rings 301 are maintained in the initial state or the use state of sliding close to each other.

[0068] Working principle: when the two L-shaped swinging rods 5 are swung upward and erected, the two clamping wheels 501 are aligned with the two positioning rings 301 and are located on the same axis, and the two positioning rings 301 are used to insert the raw material pipe, and the raw material pipe rotates in the two positioning rings 301; the threaded rocker 2 can rotate forward and reversely to drive the two vertical support slide plates 4 and the two clamping wheels 501 to slide towards each other to tighten the raw material pipe; the two L-shaped swinging rods 5 and the two clamping wheels 501 are placed in a swinging and upright state to clamp and fix the raw material pipe to be polished, and after the two clamping wheels 501 clamp and position the raw material pipe, the raw material pipe can be connected to the motor 6 for transmission, and the motor 6 is used to rotate and drive the raw material pipe to perform circumferential comprehensive grinding on the surface of the raw material pipe; when the two L-shaped swinging rods 5 and the two clamping wheels 501 are placed in a swinging and horizontal state, the space on the left and right sides of the raw material pipe can be vacated, which is convenient for the insertion and removal of the raw material pipe in the two positioning rings 301;

[0069] The two pull rods 502, the two driving sliders 1042 and the two L-shaped swinging rods 5 are connected together to form two crank rocker mechanisms. Through these two mechanisms, the two driving sliders 1042 can push and drive the two L-shaped swinging rods 5 to swing up and down, and control the two L-shaped swinging rods 5 and the two clamping wheels 501 to switch freely between the vertical clamping state and the horizontal empty state.

[0070] When the two vertical support slides 4 and the clamping wheels 501 slide away from each other to loosen the raw material tube, the two poking rods 1041 pass through the two longitudinal support blocks 402 and come into contact with the two driving slide blocks 1042, which can push and drive the two driving slide blocks 1042 to slide towards each other, and drive and control the two L-shaped swinging rods 5 and the two clamping wheels 501 to swing to a horizontal empty state; in the process of the two vertical support slides 4 and the clamping wheels 501 sliding towards each other to clamp the raw material tube, after the two driving slide blocks 1042 are separated from the two poking rods 1041, the springs on the two U-shaped positioning frames 104 can automatically rebound and push and drive the two driving slide blocks 1042 to slide away from each other and reset, and drive and control the two L-shaped swinging rods 5 and the two clamping wheels 501 to swing and reset to the upright clamping use state;

[0071] In the process of the two vertical support slide plates 4 and the clamping wheels 501 sliding towards each other to clamp the raw material pipe, when the two L-shaped swing rods 5 and the two clamping wheels 501 return to the vertical clamping state, the eight plug-in shafts 4031 can respectively plug and position the two driving slide blocks 1042 with the four rectangular positioning frames 403, so that the two L-shaped swing rods 5 and the two clamping wheels 501 are kept in the vertical clamping state, so as to implement top pressure clamping on the raw material pipe;

[0072] Through the inclined guiding principle of the inclined parts of the guide plates 105 at four locations, when the two vertical support slide plates 4 and the clamping wheel 501 slide close to each other to clamp the raw material tube, the eight plug-in shafts 4031 can be pushed and driven to slide inward synchronously, and the two driving sliders 1042 can be plugged and positioned. In the process of the two vertical support slide plates 4 and the two clamping wheels 501 sliding away from each other to loosen the raw material tube, when the eight plug-in shafts 4031 are separated from the guide plates 105 at four locations, the eight plug-in shafts 4031 can be automatically rebounded by the springs thereon to push and slide outward, and the two driving sliders 1042 can be pulled out and loosened.
