Description

Technical Field

[0001] This application relates to the technical field of pipe fitting processing, and particularly to a processing device for engine plastic pipe fittings. Background Art

[0002] The pipe fittings of an engine are one of the indispensable components in automobile manufacturing and are widely used in transmission systems such as the intake system and the fuel supply system. With the increasing demands of the automotive industry for lightweight and performance, plastic pipe fittings are widely used due to their advantages such as light weight and low cost. However, in the actual production process, pipe fittings made of a single plastic material are difficult to meet the usage requirements of all parts of the engine for pipe fittings, and some pipe fittings need to use plastic pipe fittings as the main body and be combined with fittings of other materials for use.

[0003] In the related art, there is designed an engine plastic pipe fitting, which includes a first pipe body and a second pipe body. The first pipe body is made of plastic material, and the second pipe body is made of metal material. The first pipe body is the main body of the entire plastic pipe fitting, and the second pipe body is a fitting located in the inner cavity of the first pipe body; when processing the pipe fitting, it is necessary to manually press the second pipe body into the first pipe body to form an integral plastic pipe fitting of the first pipe body and the second pipe body.

[0004] In the process of implementing this application, it is found that there are at least the following problems in this technology: during the process of manually pressing the second pipe body into the first pipe body, it is time-consuming and laborious, the assembly speed is slow, the efficiency is low, and the error caused by manual operation is large. Summary of the Invention

[0005] In order to achieve the rapid assembly between the first pipe body and the second pipe body, improve the assembly efficiency, reduce the labor cost, and reduce the error caused by manual operation, this application provides a processing device for engine plastic pipe fittings.

[0006] The processing device for engine plastic pipe fittings provided by this application adopts the following technical solutions: A processing device for engine plastic pipe fittings includes a workbench for receiving the first pipe body. A bracket is fixedly arranged on the workbench, and a mounting plate is fixedly arranged on the bracket. The mounting plate faces the workbench. A first driving member is arranged on the mounting plate, and a loading assembly is connected to the first driving member. The loading assembly is used for clamping the second pipe body, and the first driving member is used for driving the loading assembly to slide in a direction close to or away from the workbench.

[0007] By adopting the above technical solution, place the first pipe body on the workbench and ensure that the pipe orifice faces the loading assembly. Then fix the second pipe body on the loading assembly, and then perform the press-fitting operation: drive the loading assembly to slide in the direction close to the workbench by the first driving member, so that the second pipe body approaches and extends into the first pipe body. During the process of the second pipe body entering the first pipe body, a pressing force is applied by the first driving member to achieve the rapid assembly of the first pipe body and the second pipe body, improve the assembly efficiency, reduce the labor cost, and reduce the error caused by manual operation.

[0008] Preferably, a second driving member is arranged on the workbench, and a limiting plate is connected to the second driving member. The second driving member is used to drive the limiting plate to slide and fix the position of the limiting plate. The sliding direction of the limiting plate is parallel to the sliding direction of the loading assembly; the limiting plate is used to abut against the pipe orifice of the first pipe body, and a through hole is formed in the limiting plate along the sliding direction of the loading assembly for the loading assembly and the second pipe body on the loading assembly to pass through.

[0009] By adopting the above technical solution, before the press-fitting operation, the second driving member drives the limiting plate to slide to a proper position and fix it, so that the limiting plate abuts against the pipe orifice of the first pipe body to confine the first pipe body between the limiting plate and the workbench, ensuring the stability of the first pipe body during the press-fitting operation and preventing the first pipe body from running with the movement of the second pipe body. At the same time, the through hole can allow the loading assembly and the second pipe body to pass through smoothly without affecting the progress of the press-fitting operation.

[0010] Preferably, a stabilizing assembly is arranged on the workbench. The stabilizing assembly includes a fixed base, arc-shaped claws, and a rotary driving member; the fixed base is fixed on the workbench, and an arc-shaped groove adapted to the outer sidewall of the first pipe body is formed on the sidewall of the fixed base. A group of arc-shaped claws are symmetrically and hingedly arranged on the sidewall of the fixed base. The arc-shaped groove is located between a group of arc-shaped claws. The inner surface of the arc-shaped claws can be attached to and abut against the outer sidewall of the first pipe body, and the rotary driving member is used to drive the arc-shaped claws to rotate.

[0011] By adopting the above technical solution, before the press-fitting operation, place the first pipe body in the arc-shaped groove, start the rotary driving member to drive the arc-shaped claws to rotate, so that the inner surface of the arc-shaped claws is closely attached to and abuts against the outer sidewall of the first pipe body, thereby firmly clamping the first pipe body from both sides. During the process of press-fitting the second pipe body, it helps to further prevent the main body of the first pipe body from displacing or shaking, further ensuring the stability of the press-fitting operation and improving the processing quality and assembly efficiency of the pipe fittings.

[0012] Preferably, the rotating driving component includes a winding wheel, a tension rope, a first reversing wheel, and a second reversing wheel. The winding wheel is fixedly connected to the arc-shaped claw. The first reversing wheel is rotatably set on a fixed base, and the second reversing wheel is rotatably set at the bottom of the mounting plate 12. One end of the tension rope is fixed and wound on the winding wheel, and the other end of the tension rope is connected to the limit plate after reversing between the first reversing wheel and the second reversing wheel; when the tension rope is detached from the winding wheel, the arc-shaped claw deflects in the direction close to the arc-shaped groove.

[0013] By adopting the above technical solution, when the limit plate slides toward the fixed base under the action of the second driving member, the end of the tension rope close to the limit plate is tightened, and the end of the tension rope close to the winding wheel is pulled and separated from the winding wheel, and the winding wheel is forced to rotate in the direction of releasing the tension rope. At this time, the arc-shaped claw deflects with the winding wheel toward the arc-shaped groove, thereby clamping the outer wall of the first tube body. When the limit plate slides away from the fixed base under the action of the second driving member, the tension rope is loosened, and the winding wheel rotates in the opposite direction under the action of the reset force to rewind the tension rope, and the arc-shaped claw deflects away from the arc-shaped groove, releasing the clamping of the first tube body, making it convenient to remove or replace the first tube body.

[0014] Preferably, the rotating driving component also includes a telescopic spring, the tension rope and the limit plate are connected through the telescopic spring, one end of the telescopic spring is fixedly connected to the limit plate, and the other end of the telescopic spring is fixedly connected to the end of the tension rope away from the winding wheel, and when the limit plate is against the pipe mouth of the first tube body, the telescopic spring is in a stretched state.

[0015] There may be deviations in the distance from the mouth of different first tubes to the surface of the workbench. If the tension rope is used alone to pull the winding wheel to rotate, when the limit plate abuts against the mouth of the first tube, the arc claw needs to rotate just to fit and abut against the outer wall of the first tube. Otherwise, if the arc claw rotates insufficiently, the clamping force of the arc claw on the first tube is insufficient. If the arc claw rotates too much, the arc claw may squeeze and deform the first tube made of plastic. By adopting the above technical solution, the telescopic spring and the tension rope are combined to form a whole that can be stretched at one end. When the arc claw rotates to fit and abut against the outer wall of the first tube, the limit plate continues to slide. At this time, it is not the pulling rope that moves, but the telescopic spring that begins to be stretched until the limit plate abuts against the mouth of the first tube. This can adapt to first tubes with different mouth heights and try to avoid the poor clamping effect of the arc claw on the first tube due to the difference in mouth height.

[0016] Preferably, the rotary drive member further comprises a reset torsion spring, and the reset torsion spring drives the winding wheel to rotate in the direction of winding the tension rope.

[0017] By adopting the above technical solution, the reset torsion spring provides a reset force for the winding wheel. When the limiting plate slides away from the fixed base to relax the tension rope, the reset torsion spring can quickly drive the winding wheel to wind up the tension rope, causing the arc-shaped claw to deflect away from the arc-shaped groove, thereby releasing the clamping of the first pipe body and keeping the tension rope still in a taut state to prevent the tension rope from derailing from the first deflection wheel or the second deflection wheel.

[0018] Preferably, a pipe orifice positioning assembly is provided on one side of the limiting plate facing the workbench. The pipe orifice positioning assembly includes positioning sliders and a positioning driving member. A plurality of positioning sliders are uniformly arranged around the center of the through hole. The positioning sliders are slidably connected to the limiting plate, and the straight line where the sliding direction of the positioning sliders is located passes through the center of the through hole. The positioning driving member is used to drive all the positioning sliders to slide, and the inner ends of the positioning sliders are used to abut against the side wall of the orifice of the first pipe body.

[0019] By adopting the above technical solution, before the press-fitting operation, the positioning driving member drives the positioning sliders to slide, so that the inner ends of the positioning sliders abut against the side wall of the end of the first pipe body, thereby accurately positioning the orifice position of the first pipe body, ensuring the coaxiality between the orifice of the first pipe body and the through hole, and even the coaxiality with the second pipe body, and reducing the jamming when the second pipe body and the first tank body are fitted together.

[0020] Preferably, the positioning driving member includes a gear ring, a driving gear, a motor, and a pushing block. The gear ring is rotatably fitted with the limiting plate, and the axis of the gear ring coincides with the axis of the through hole. The driving gear is rotatably fitted with the limiting plate, and the driving gear meshes with the gear ring. The motor is used to drive the driving gear to rotate; a plurality of pushing blocks are fixedly arranged on the inner wall of the gear ring, and the pushing blocks correspond to the positioning sliders one by one. A pushing surface is formed on the side of the pushing block facing away from the gear ring. One end of the pushing surface is close to the gear ring, and the other end of the pushing surface is far from the gear ring. The pushing surface abuts against the end of the positioning slider away from the through hole.

[0021] By adopting the above technical solution, the motor drives the driving gear to rotate, driving the meshing gear ring to rotate. As the gear ring rotates, the pushing blocks on the inner wall of the gear ring move accordingly. Since the pushing surface on the pushing block abuts against the end of the positioning slider away from the through hole, and one end of the pushing surface is close to the inner wall of the gear ring and the other end is far from the inner wall of the gear ring, the inclined structure of the pushing surface will push the positioning slider to move along the sliding direction. Thus, the positioning sliders are synchronously moved closer to each other, accurately positioning and fixing the orifice of the first pipe body, ensuring the coaxiality between the orifice of the first pipe body and the through hole and even the second pipe body, effectively reducing the jamming phenomenon when the second pipe body and the first pipe body are fitted together, and improving the smoothness of the press-fitting.

[0022] Preferably, the loading assembly comprises an abutment block and a support member, wherein the abutment block is used to abut against the top end of the second tube body, and the support member can extend into the second tube body and abut against the inner wall of the second tube body.

[0023] By adopting the above technical solution, the abutment block abuts against the end of the second tube body, which can provide a force-bearing surface for the second tube body during press-fitting, so that the press-fitting force is evenly transmitted along the axial direction of the second tube body; the support member extends into the second tube body and abuts against the inner wall of the second tube body, thereby generating friction force, which can prevent the second tube body from falling off the loading assembly without being affected by external force.

[0024] Preferably, the support member includes an inserted column block and a spring leaf, the inserted column block is fixedly arranged on a side of the abutment block facing the workbench, a number of spring leaves are evenly distributed along the circumferential direction of the inserted column block, the top end of the spring leaf is fixedly connected to the side wall of the top of the inserted column block, the bottom end of the spring leaf is fixedly connected to the side wall of the bottom of the inserted column block, the middle part of the spring leaf is bent in a direction away from the axis of the inserted column block, and the middle part of the spring leaf is used to press against the inner wall of the second tube body.

[0025] By adopting the above technical solution, after the support member is inserted into the second tube body, the middle part of the bent spring piece on the support member abuts against the inner wall of the second tube body to generate friction, which can prevent the second tube body from falling off the loading assembly when no external force is applied, thereby ensuring the stability and continuity of the press-fitting operation. At the same time, the bent spring piece naturally forms an arc in the axial direction of the inserted column block. Under the joint action of all the spring pieces, the inserted column block forms a shape with small diameters at both ends and large diameters in the middle, which facilitates guiding the second tube body to be inserted from one end.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a workbench, a first driving member, a loading assembly, a second driving member, a limit plate, and a through hole, the first tube body and the second tube body can be quickly assembled, the assembly efficiency can be improved, the labor cost can be reduced, and the error caused by manual operation can be reduced; 2. By setting a fixed base, an arc groove, an arc claw, a winding wheel, a tension rope, a first reversing wheel, a second reversing wheel, a telescopic spring, and a reset torsion spring, when the limit plate abuts against the pipe opening of the first tube body, the arc claw can hold the outer wall of the first tube body tightly in the arc groove, thereby fixing the main body of the first tube body; 3. By setting an abutment block, an extending column block, and a spring leaf, the abutment block provides a force-bearing surface for the second tube body during press-fitting, and a support member composed of the extending column block and the spring leaf generates friction through the contact between the spring leaf and the inner wall of the second tube body, thereby preventing the second tube body from falling off from the loading assembly without being affected by external force.

Detailed implementation manners

[0033] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 drawings.

[0034] An embodiment of the present application discloses a processing device for engine plastic pipe fittings. Referring to Figure 1 and Figure 2 , it includes a workbench 1, and the workbench 1 is used to receive the first pipe body 6. A bracket 11 is vertically and fixedly arranged on the workbench 1, and a mounting plate 12 is fixedly arranged at the top of the bracket 11. The mounting plate 12 faces the workbench 1. A first driving member 121 is arranged on the mounting plate 12, and a loading assembly 2 is connected to the first driving member 121. The loading assembly 2 is used to clamp the second pipe body 7. The first driving member 121 is used to drive the loading assembly 2 to slide in a direction close to or away from the workbench 1. In this embodiment, the first driving member 121 is a first air cylinder, the first air cylinder is vertically and fixedly arranged on the mounting plate 12, and the output end of the first air cylinder penetrates through the mounting plate 12 and is fixedly connected to the loading assembly 2.

[0035] Reference Figure 1 When Figure 2 , when performing the combined processing of the second tube body 7 and the first tube body 6, first perform the feeding operation: place the first tube body 6 on the workbench 1 with the tube orifice facing the loading component 2 directly, and clamp the second tube body 7 on the loading component 2. Then perform the press-fitting operation: drive the loading component 2 to slide towards the direction close to the workbench 1 through the first cylinder, and the second tube body 7 approaches the workbench 1 accordingly. During this process, the first cylinder applies a pressing force to the second tube body 7 to press the second tube body 7 into the first tube body 6. In this way, the rapid assembly of the first tube body 6 and the second tube body 7 is realized, the assembly efficiency is improved, the labor cost is reduced, and the error caused by manual operation is reduced.

[0036] To facilitate the rapid clamping of the second tube body 7, reference Figure 3 When Figure 4 , the loading component 2 includes an abutting block 21 and a supporting member 22. The abutting block 21 is used to abut against the top end of the second tube body 7, and the supporting member 22 can extend into the second tube body 7 and abut against the inner wall of the second tube body 7. Among them, the supporting member 22 includes an extending column block 221 and a reed 222. The extending column block 221 is fixedly arranged on the side of the abutting block 21 facing the workbench 1. A plurality of reeds 222 are evenly distributed along the circumferential direction of the extending column block 221. The top end of the reed 222 is fixedly connected to the side wall of the top of the extending column block 221, the bottom end of the reed 222 is fixedly connected to the side wall of the bottom of the extending column block 221, and the middle part of the reed 222 bends towards the direction away from the axis of the extending column block 221. The middle part of the reed 222 is used to abut against the inner wall of the second tube body 7.

[0037] Reference Figure 3 When Figure 4 , when clamping the second tube body 7, directly sleeved the tube orifice of the second tube body 7 from the bottom of the extending column block 221 towards the extending column block 221, and the reed 222 on the side wall of the extending column block 221 is deformed by the extrusion of the inner wall of the second tube body 7. The reed 222 abuts against the inner wall of the second tube body 7 to prevent the second tube body 7 from falling off the loading component 2 when not affected by external force, so as to quickly clamp the second tube body 7. When the second tube body 7 enters the first tube body 6, the abutting block 21 provides a stress surface for the top end of the second tube body 7 to ensure the pressure received by the second tube body 7 when being pressed.

[0038] To improve the stability of the first tube body 6 in the vertical direction and facilitate the separation of the second tube body 7 from the loading component 2, reference Figure 1 When Figure 2, a second driving member 13 is provided on the workbench 1, a limiting plate 3 is connected to the second driving member 13, the second driving member 13 is used to drive the limiting plate 3 to slide and fix the position of the limiting plate 3, and the sliding direction of the limiting plate 3 is parallel to the sliding direction of the loading assembly 2. In this embodiment, the second driving member 13 is a second cylinder, the second cylinder is vertical and fixed on the workbench 1, and the output end of the second cylinder faces upward and is fixedly connected to the limiting plate 3. The limiting plate 3 is used to abut against the pipe orifice of the first pipe body 6, and a through hole 31 is formed in the limiting plate 3 along the sliding direction of the loading assembly 2 for the loading assembly 2 and the second pipe body 7 on the loading assembly 2 to pass through.

[0039] Referring to Figure 1 and Figure 2 , before pressing the second pipe body 7 into the first pipe body 6, the limiting plate 3 is abutted against the pipe orifice of the first pipe body 6 by the second cylinder, so as to confine the first pipe body 6 between the limiting plate 3 and the workbench 1 and ensure the stability of the first pipe body 6 in the vertical direction. In addition, after the second pipe body 7 is pressed into the first pipe body 6, the first cylinder drives the loading assembly 2 to move upward. The top of the first pipe body 6 is restricted by the limiting plate 3 and cannot move upward, thereby hindering the upward movement of the first pipe body 6 and the second pipe body 7 that has completed the fit with the inner wall of the first pipe body 6. The second pipe body 7 disengages from the reed 222 of the loading assembly 2, thus completing the separation of the second pipe body 7 from the loading assembly 2.

[0040] In order to improve the stability of the first pipe body 6 in the horizontal direction, referring to Figure 1 and Figure 2 , a stabilizing assembly 4 is further provided on the workbench 1. The stabilizing assembly 4 includes a fixed base 41, an arc claw 42, and a rotation driving member 43. The fixed base 41 is fixed on the workbench 1, and an arc groove 411 adapted to the outer side wall of the first pipe body 6 is formed on the side wall of the fixed base 41. A set of arc claws 42 are symmetrically and hingedly arranged on the side wall of the fixed base 41. The arc groove 411 is located between a set of arc claws 42, and the inner surface of the arc claw 42 can be attached to and abut against the outer side wall of the first pipe body 6. The rotation driving member 43 is used to drive the arc claw 42 to rotate.

[0041] Referring to Figure 1 and Figure 2, the rotation driving member 43 includes a winding wheel 431, a pulling rope 432, a first reversing wheel 433, a second reversing wheel 434, a telescopic spring 435, and a reset torsion spring 436. The winding wheel 431 is fixedly connected to the top of the hinge shaft of the arc-shaped claw 42. The first reversing wheel 433 is rotatably arranged on the top of the fixed base 41, and the second reversing wheel 434 is rotatably arranged at the bottom of the mounting plate 12. One end of the pulling rope 432 is fixed and wound around the winding wheel 431, and the other end of the pulling rope 432 is connected to the limiting plate 3 after being reversed by the first reversing wheel 433 and the second reversing wheel 434. When the pulling rope 432 is separated from the winding wheel 431, the arc-shaped claw 42 deflects towards the direction close to the arc-shaped groove 411. Specifically, the pulling rope 432 is connected to the limiting plate 3 through the telescopic spring 435. The bottom end of the telescopic spring 435 is fixedly connected to the limiting plate 3, and the top end of the telescopic spring 435 is fixedly connected to the end of the pulling rope 432 away from the winding wheel 431. And when the limiting plate 3 abuts against the pipe orifice of the first pipe body 6, the telescopic spring 435 is in a stretched state. The reset torsion spring 436 is sleeved on the hinge shaft of the arc-shaped claw 42, and one end is fixedly connected to the fixed base 41, and the other end is fixedly connected to the arc-shaped claw 42. The reset torsion spring 436 drives the arc-shaped claw 42 to rotate, and further drives the winding wheel 431 to rotate in the direction of winding the pulling rope 432.

[0042] Referring to Figure 1 and Figure 2 , before the press-fitting operation, the first pipe body 6 is placed in the arc-shaped groove 411. The second cylinder drives the limiting plate 3 to move downward, and the pulling rope 432 is pulled and tightened by the limiting plate 3, and then separated from the winding wheel 431. The winding wheel 431 is forced to rotate in the direction of releasing the pulling rope 432, and the arc-shaped claw 42 deflects towards the direction close to the arc-shaped groove 411 along with the winding wheel 431, so as to tightly hold the first pipe body 6 in the arc-shaped groove 411 and improve the stability of the first pipe body 6 in the horizontal direction. As the limiting plate 3 continues to move downward, the telescopic spring 435 begins to be stretched until the limiting plate 3 abuts against the pipe orifice of the first pipe body 6, so as to adapt to the first pipe body 6 with different pipe orifice heights. On the contrary, after the press-fitting operation is completed, the second cylinder drives the limiting plate 3 to move upward. After the telescopic spring 435 contracts, the pulling rope 432 is relaxed, and the reset torsion spring 436 drives the arc-shaped claw 42 to rotate, so that the processed first pipe body 6 is released and can be separated from the arc-shaped groove 411, and the winding wheel 431 rotates in the direction of winding the pulling rope 432 to complete the reset.

[0043] To ensure the coaxiality of the pipe orifice of the first pipe body 6 with the through hole 31 and even the second pipe body 7, referring to Figure 4 and Figure 5, on the side of the limit plate 3 facing the workbench 1, a pipe orifice positioning assembly 5 is provided. The pipe orifice positioning assembly 5 includes a positioning slider 51 and a positioning driving member 52. A plurality of positioning sliders 51 are evenly arranged around the center of the through hole 31. The positioning slider 51 is slidably connected to the limit plate 3, and the straight line where the sliding direction of the positioning slider 51 is located passes through the center of the through hole 31. The positioning driving member 52 is used to drive all the positioning sliders 51 to slide, and the inner end of the positioning slider 51 is used to abut against the side wall of the orifice of the first pipe body 6. In this embodiment, three positioning sliders 51 are provided. At the bottom of the limit plate 3, three dovetail grooves 32 are evenly opened around the through hole 31. A dovetail block 322 is integrally formed at the top of the positioning slider 51. The dovetail groove 32 and the dovetail block 322 correspond to each other one by one and are in sliding fit.

[0044] Referring to Figure 4 and Figure 5 , the positioning driving member 52 includes a gear ring 521, a driving gear 522, a motor 525, and a pushing block 523. The gear ring 521 is rotatably engaged with the limit plate 3, and the axis of the gear ring 521 coincides with the axis of the through hole 31. The driving gear 522 is rotatably engaged with the limit plate 3, and the driving gear 522 meshes with the gear ring 521. The motor 525 is used to drive the driving gear 522 to rotate. Specifically, the motor 525 is fixedly connected to the limit plate 3, and the driving shaft of the motor 525 is coaxially and fixedly connected to the driving gear 522. Three pushing blocks 523 are fixedly arranged on the inner wall of the gear ring 521, and the pushing blocks 523 correspond to the positioning sliders 51 one by one. On the side of the pushing block 523 facing away from the gear ring 521, a pushing surface 5231 is provided. One end of the pushing surface 5231 is close to the gear ring 521, and the other end of the pushing surface 5231 is far from the gear ring 521. The pushing surface 5231 abuts against the end of the positioning slider 51 away from the through hole 31. In this embodiment, a pressing spring 321 is further arranged in the dovetail groove 32. One end of the return spring is fixedly connected to the dovetail block 322, and the other end is fixedly connected to the end wall of the dovetail groove 32 away from the through hole 31. The return spring urges the return spring to be close to the end wall of the dovetail groove 32 away from the through hole 31, thereby urging the positioning slider 51 to keep abutting against the pushing surface 5231.

[0045] Referring to Figure 4 and Figure 5 , after the limit plate 3 abuts against the orifice of the first pipe body 6, the motor 525 drives the driving gear 522 to rotate, driving the gear ring 521 to rotate. The pushing blocks 523 on the inner wall of the gear ring 521 rotate accordingly, and the pushing surface 5231 of the pushing block 523 pushes the positioning slider 51 to move along the sliding direction of the positioning slider 51. Thus, all the positioning sliders 51 jointly abut against the side wall of the orifice of the first pipe body 6. Positioning and fixing the orifice of the first pipe body 6 ensures the coaxiality of the orifice of the first pipe body 6 with the through hole 31 and even the second pipe body 7, and reduces the jamming phenomenon when the second pipe body 7 and the first pipe body 6 start to enter the fit.

[0046] The implementation principle of a processing device for engine plastic pipe fittings in an embodiment of the present application is as follows: When combining and processing the second pipe body 7 and the first pipe body 6, the feeding operation is first carried out: The pipe orifice of the second pipe body 7 is sleeved onto the extending column block 221, and the reed 222 abuts against the inner wall of the second pipe body 7 to complete the clamping of the second pipe body 7. The first pipe body 6 is placed in the arc-shaped groove 411. Then, the limiting plate 3 is driven to move downward by the second air cylinder (i.e., the second driving member 13), and the pulling rope 432 is pulled and tightened by the limiting plate 3, and then disengages from the winding wheel 431. The winding wheel 431 is forced to rotate in the direction of releasing the pulling rope 432, and the arc-shaped claw 42 deflects towards the arc-shaped groove 411 along with the winding wheel 431, so as to tightly hold the first pipe body 6 in the arc-shaped groove 411. As the limiting plate 3 continues to move downward, the telescopic spring 435 begins to be stretched until the limiting plate 3 abuts against the pipe orifice of the first pipe body 6, thereby fixing the first pipe body 6. Then, the motor 525 drives the driving gear 522 to rotate, and then drives the gear ring 521 to rotate. The pushing surface 5231 of the pushing block 523 pushes the positioning slider 51 to slide close to the through hole 31. All the positioning sliders 51 jointly abut against the side wall of the pipe orifice of the first pipe body 6. Positioning and fixing the pipe orifice of the first pipe body 6 ensures the coaxiality of the pipe orifice of the first pipe body 6 with the through hole 31 and even the second pipe body 7. Finally, the press-fitting operation is carried out: The second pipe body 7 is driven to approach the first pipe body 6 by the first air cylinder (i.e., the first driving member 121). The first air cylinder applies a pressing force to the second pipe body 7 through the abutting block 21, and presses the second pipe body 7 into the first pipe body 6. In this way, the rapid assembly of the first pipe body 6 and the second pipe body 7 is realized, the assembly efficiency is improved, the labor cost is reduced, and the error caused by manual operation is reduced.

[0047] After the press-fitting operation is completed, the second air cylinder drives the limiting plate 3 to move upward. After the telescopic spring 435 contracts, the pulling rope 432 is relaxed, and the reset torsion spring 436 drives the arc-shaped claw 42 to rotate, so that the processed first pipe body 6 is released and can be separated from the arc-shaped groove 411, and the winding wheel 431 rotates in the direction of winding the pulling rope 432 to complete the reset.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
