Description

Technical Field

[0001] This utility model relates to the field of automated intelligent production equipment for functional pipe fittings, specifically to a pipe intermediate section assembly device. Background Technology

[0002] A functional pipe fitting is needed, comprising: a straight pipe with a locking head inserted at one end, and a rivet point at the end of the pipe with the locking head to secure it; an end cap at the other end of the pipe, with a ring of glue applied to its inner wall before assembly to secure it to the pipe end; and an intermediate section pre-installed on the straight pipe. All three components—the locking head, end cap, and intermediate section—are made of plastic. Currently, the installation of these three plastic components is done manually. Manual installation of plastic components suffers from low processing efficiency, high labor costs, and inconsistent assembly quality. To achieve automated production, there is an urgent need for a pipe intermediate section assembly device suitable for automated assembly lines that can automatically install intermediate sections. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pipe intermediate section assembly device that can automatically assemble intermediate sections on an automated production line.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a pipe intermediate section assembly device, comprising: a frame, characterized in that: an intermediate section mounting seat that can slide left and right is provided on the frame, and an intermediate section pushing mechanism that can drive the intermediate section mounting seat to move left and right; an intermediate section feeding finger arranged horizontally in a front-back direction is provided on the intermediate section mounting seat, and an intermediate section rotary cylinder that can drive the intermediate section feeding finger to swing back and forth 180 degrees upward; a mandrel arranged horizontally in a left-right direction and a mandrel driving mechanism that can drive the mandrel to move left and right; a lever and a lever driving mechanism that can drive the lever to move left and right; the intermediate section feeding finger can be perpendicular to the intermediate section axis to the middle. The mandrel is gripped and then swung upwards 180 degrees to move the gripped middle section to the opposite side of the mandrel. At this time, the mandrel extends towards the middle section under the drive of the mandrel drive mechanism. The mandrel can pass through the middle section, so that the middle section can be fitted onto the mandrel. Thus, after the middle section is released by the feeding finger, the middle section can remain on the mandrel. Then, the middle section mounting seat moves towards the positioned left-right straight tube under the drive of the middle section pushing mechanism. The head of the mandrel can be inserted into the port of the straight tube under the drive of the middle section mounting seat. Then, the lever moves towards the straight tube under the drive of the lever drive mechanism. The lever can push the middle section, so that the middle section can slide along the mandrel onto the straight tube.

[0005] Furthermore, in the aforementioned intermediate pipe section assembly device: a shaping cylinder finger is provided on the frame inside the mandrel; a clamping block is installed on each of the two clamping fingers of the shaping cylinder finger; a shaping groove and a clamping groove are respectively provided on the opposite sidewalls of the two clamping blocks; the shaping groove is located outside the clamping groove; the outer end of the shaping groove is beveled; after the shaping cylinder finger drives the two clamping blocks to clamp together, the two clamping grooves can clamp the outside of the straight pipe to position the straight pipe; and the two shaping grooves can encircle the end of the straight pipe. At this time, there is an annular gap between the two shaping grooves and the straight pipe that allows the intermediate section to pass through. When the intermediate section is pushed and slid towards the end of the straight pipe, the head of the intermediate section will first enter the two opposing shaping grooves under the guidance of the bevel; the two opposing shaping grooves can pre-round the intermediate section, so that the intermediate section can smoothly slide onto the straight pipe.

[0006] Furthermore, in the aforementioned intermediate pipe section assembly device, two wide-type cylinder fingers arranged side-by-side, a backing plate, and a backing drive mechanism that can drive the backing plate to move left and right are provided on the frame. The straight pipe is supported and positioned on the frame in a left-right direction by being clamped by the two wide-type cylinder fingers at both ends. The backing plate can be used for the straight pipe to abut against when the intermediate section is installed. The backing drive mechanism can drive the backing plate away from the straight pipe so as not to hinder the transfer of the straight pipe.

[0007] Furthermore, the aforementioned intermediate pipe section assembly device further includes an intermediate section supply mechanism. The intermediate section supply mechanism comprises an intermediate section vibratory plate for providing intermediate sections, an intermediate section conveying channel on the intermediate section vibratory plate, intermediate sections conveyed outward by the intermediate section vibratory plate sliding downward and arranging in the intermediate section conveying channel, intermediate section feeding fingers located between the intermediate section conveying channel and the mandrel, and an avoidance notch provided at the lower end of the intermediate section conveying channel. The intermediate section feeding fingers can pass through the avoidance notch to grip the first intermediate section arranged in the intermediate section conveying channel from top to bottom. Furthermore, due to the open upper surface at the lower end of the intermediate section conveying channel and the baffle at the lower port of the intermediate section conveying channel being set as an arc-shaped plate that can avoid intermediate sections, the intermediate section feeding fingers can swing upward under the drive of the intermediate section rotary cylinder and bring the gripped intermediate section away from the intermediate section conveying channel.

[0008] Furthermore, in the aforementioned intermediate pipe section assembly device, an intermediate section stop block and an intermediate section stop block drive mechanism are provided above the lower end of the intermediate section conveying channel. After the intermediate section stop block moves downward under the drive of the intermediate section stop block drive mechanism, it can press the second intermediate section in the intermediate section conveying channel so that the intermediate section does not prevent the first intermediate section from leaving the intermediate section conveying channel.

[0009] Furthermore, in the aforementioned intermediate pipe section assembly device, the intermediate section conveying channel is fixed on a linear vibrator.

[0010] Furthermore, in the aforementioned intermediate pipe section assembly device, the paddle is annular and is fitted onto the mandrel.

[0011] The advantages of this utility model are: the pipe intermediate section assembly device can be applied to automated production lines and can realize the automatic installation of intermediate sections, which greatly improves the processing efficiency of pipe fittings, greatly reduces labor costs, and improves assembly quality.

[0015] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, the pipe intermediate section assembly device includes: a frame 1, on which is mounted an intermediate section mounting seat 2 that can slide left and right, and an intermediate section pushing mechanism that can drive the intermediate section mounting seat 2 to move left and right. The intermediate section mounting seat 2 is mounted on the frame 1 via a linear guide rail. On the intermediate section mounting seat 2, there is an intermediate section feeding finger 3 arranged horizontally in a front-to-back direction, and an intermediate section rotary cylinder 4 that can drive the intermediate section feeding finger 3 to swing back and forth 180 degrees upwards; a mandrel 5 arranged horizontally in a left-to-right direction and a mandrel driving mechanism that can drive the mandrel 5 to move left and right; a lever 6 and a lever driving mechanism that can drive the lever 6 to move left and right; the intermediate section feeding finger 3 is a pneumatic finger, and the intermediate section feeding finger 3 can be perpendicular to the intermediate section 7 axially. The gripper makes a grasping motion, and after swinging upwards 180 degrees, it moves the gripped intermediate section 7 to the opposite side of the mandrel 5. At this time, the mandrel 5 extends towards the intermediate section 7 under the drive of the mandrel drive mechanism. The mandrel 5 passes through the intermediate section 7, allowing the intermediate section 7 to be fitted onto the mandrel 5. Thus, after the intermediate section feeding finger 3 releases the intermediate section 7, the intermediate section 7 remains on the mandrel 5. Then, the intermediate section mounting seat 2 moves towards the positioned left-right straight tube 8 under the drive of the intermediate section pushing mechanism. The head of the mandrel 5 can be inserted into the port of the straight tube 8 under the drive of the intermediate section mounting seat 2. Then, the lever 6 moves towards the straight tube 8 under the drive of the lever drive mechanism. The lever 6 can push the intermediate section 7, allowing the intermediate section 7 to slide along the mandrel 5 onto the straight tube 8.

[0017] In this embodiment, the paddle 6 is ring-shaped and is fitted onto the core rod 5. The ring-shaped paddle 6 can more reliably push the intermediate section 7.

[0018] An intermediate section supply mechanism is also provided. The structure of the intermediate section supply mechanism includes: an intermediate section vibratory plate 9 that provides intermediate sections 7, an intermediate section conveying channel 10 provided on the intermediate section vibratory plate 9, the intermediate sections 7 conveyed outward by the intermediate section vibratory plate 9 will slide downward and be arranged in the intermediate section conveying channel 10, the intermediate section feeding finger 3 is located between the intermediate section conveying channel 10 and the mandrel 5, the lower end of the intermediate section conveying channel 10 is provided with a clearance notch, the intermediate section feeding finger 3 can pass through the clearance notch to grip the first intermediate section 7 arranged in the intermediate section conveying channel 10 from the top and bottom, and because the upper surface of the lower end of the intermediate section conveying channel 10 is open and the baffle 11 on the lower port of the intermediate section conveying channel 10 is set as an arc plate that can avoid the intermediate section 7, the intermediate section feeding finger 3 can swing upward under the drive of the intermediate section rotary cylinder 4 and bring the gripped intermediate section 7 away from the intermediate section conveying channel 10.

[0019] To prevent the intermediate section 7 from being affected by the next intermediate section 7 when it is being carried away, an intermediate section stop block 12 and an intermediate section stop block drive mechanism are provided above the lower end of the intermediate section conveying channel 10. After the intermediate section stop block 12 moves downward under the drive of the intermediate section stop block drive mechanism, it can press the second intermediate section 7 in the intermediate section conveying channel 10, so that the intermediate section 7 can leave the intermediate section conveying channel 10 without hindering the first intermediate section 7 from leaving the intermediate section conveying channel 10.

[0020] To position the straight pipe 8, two wide cylinder fingers 13 arranged side to side, a backing plate 14, and a backing drive mechanism that can drive the backing plate 14 to move left and right are provided on the frame 1. The straight pipe 8 is supported and positioned on the frame 1 in a left-right direction by being clamped by the two wide cylinder fingers 13 at both ends. The backing plate 14 can be used for the straight pipe 8 to abut when the intermediate section 7 is installed. The backing drive mechanism can drive the backing plate 14 away from the straight pipe 8 so as not to hinder the transportation of the straight pipe 8.

[0021] To better transport the intermediate section 7, the intermediate section transport channel 10 is fixed to the linear vibrator 15.

[0022] A shaping cylinder finger 16 is provided on the frame 1 inside the mandrel 5. A clamping block 17 is installed on each of the two clamping fingers of the shaping cylinder finger 16. A shaping groove 19 and a clamping groove 18 are respectively provided on the opposite side walls of the two clamping blocks 17. The shaping groove 19 is located outside the clamping groove 18. The outer port of the shaping groove 19 is beveled. After the shaping cylinder finger 16 drives the two clamping blocks 17 to clamp together, the two clamping grooves 18 can clamp the outside of the straight tube 8 to position the straight tube 8. The two shaping grooves 19 can surround the end of the straight tube 8. An annular gap is left between the two shaping grooves 19 and the straight tube 8 to allow the intermediate section 7 to pass through. When the intermediate section 7 is pushed and slid towards the end of the straight tube 8, the head of the intermediate section 7 will first enter the two opposing shaping grooves 19 under the guidance of the bevel. The two opposing shaping grooves 19 can pre-round the intermediate section 7, so that the intermediate section 7 can smoothly slide onto the straight tube 8.

[0023] The intermediate section pushing mechanism, mandrel driving mechanism, intermediate section stop block driving mechanism, and abutment driving mechanism are all cylinders. The paddle driving mechanism includes a cylinder and a long plate. The long plate moves left and right under the drive of the cylinder, and the paddle 6 is mounted on the long plate.
