Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to an automatic thread rolling machine for joints. Background Art
[0002] In real life, there is a Fig. 9 The connector 30 shown has one end with a smaller outer diameter and one end with a larger outer diameter. When in use, the end with the larger outer diameter is required to have a thread. Since the wall of this connector is relatively thin, if the thread is directly processed by tapping, it is easy to tap through the wall, so the thread can only be processed by rolling.
[0003] Specifically, two parallel inner and outer rolling rollers are used. After the end with a larger outer diameter of the joint is put on the inner rolling roller, it is supported by a top, and then the outer rolling roller moves closer to the inner rolling roller. After the outer rolling roller contacts the outer wall of the end with a larger outer diameter of the joint, the outer rolling roller, the inner rolling roller, the joint and the top rotate together, thereby rolling out the thread on the joint. In practice, the joints are loaded and unloaded manually, and the low degree of automation leads to low production efficiency. Utility Model Content
[0004] The utility model aims to solve the above problems in the prior art and proposes an automatic thread rolling machine for joints, thereby solving the problem of low production efficiency.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] The automatic joint rolling machine comprises a frame, a rolling assembly and a guide member, both of which are arranged on the frame, the rear end of the guide member is a feeding end, and the front end of the guide member is a discharging end arranged downwardly inclined relative to the rear end, and is characterized in that the frame is also provided with a material receiving member located below the discharging end of the guide member and a top and bottom material assembly located on the right side of the rolling assembly. The top and bottom material assembly comprises a main sliding seat that can slide forward and backward, and a secondary sliding seat one and a secondary sliding seat two that are both arranged on the main sliding seat and can slide left and right. The secondary sliding seat one is provided with a pushing rod with an end facing the rolling assembly and can rotate around its own center line relative to the secondary sliding seat one. The secondary sliding seat two is located in front of the secondary sliding seat one and the secondary sliding seat two is connected to a hand claw arranged towards the rolling assembly. The material receiving member is provided with a material receiving groove that runs through its left side wall, and the material receiving member can move forward and backward so that the material receiving groove can reciprocate between the rolling assembly and the upper and lower assembly and below the discharging end of the material guide member.
[0007] When in use, the feed end of the material guide is connected to the vibrator, and the vibrator sequentially guides the joint into the material guide with the center line set to the left and the end with the larger outer diameter facing the left. Initially, the material receiving piece is in a state where the receiving trough is located below the discharge end of the material guide, and the joint falls from the material guide into the receiving trough, and then the piston rod of the material receiving cylinder pushes out and drives the material receiving piece to slide forward, so that the material receiving trough moves to between the thread rolling assembly and the upper and lower material assemblies, and then the piston rod of the auxiliary driving cylinder pushes out and drives the push rod to extend and insert the end with the smaller outer diameter of the joint, and the push rod will push the joint out of the receiving trough and send the end with the larger outer diameter to the thread rolling assembly for thread rolling. When the push rod pushes the joint onto the thread rolling assembly, the material receiving piece is reset to the initial position. After the thread rolling is completed, the push rod is reset to the right, and then the main driving cylinder drives the main sliding seat to move to the right and switch to the auxiliary sliding seat 2 to face the joint located at the thread rolling assembly. Then the auxiliary driving cylinder 2 drives the claw to move to the left and clamp the threaded joint and remove it from the thread rolling assembly. Through the above settings, automatic loading and unloading of joints can be achieved during thread rolling, which improves production efficiency.
[0008] In the above-mentioned automatic thread rolling machine for joints, the material receiving piece is arranged in a long block shape along the front-to-back direction, and the material receiving groove is located at the front end of the material receiving piece.
[0009] Through the above arrangement, when the material receiving piece moves forward and the material receiving trough moves from below the discharge end of the material guide piece to a position between the rolling assembly and the upper and lower material assemblies, the rear upper side surface of the material receiving piece will block the front end of the material guide plate to prevent the remaining joints from being sent forward by the material receiving piece at the same time.
[0010] In the above-mentioned automatic thread rolling machine for joints, the material guide member includes a material guide plate and baffles connected to the left and right sides of the material guide plate. The front end of the left baffle has a blocking plate arranged horizontally forward, and the position between the thread rolling assembly and the upper and lower material assemblies is located in front of the blocking plate.
[0011] Because the material receiving trough runs through the left side wall of the material receiving piece, a horizontal forward blocking plate is set at the front end of the left baffle to prevent the joint in the material receiving trough from falling out of the material receiving trough during the process of being transported from the discharge end of the material guide piece to the position between the rolling assembly and the upper and lower material assemblies.
[0012] In the above-mentioned automatic thread rolling machine for joints, a support seat and a positioning seat in front of the support seat are fixed on the frame, the material guide piece is fixedly connected to the top of the support seat, a material receiving cylinder and a material receiving slide rail are fixed on the positioning seat, a material receiving slide rail is provided with a material receiving sliding seat fixedly connected to the end of the piston rod of the material receiving cylinder, and the rear end of the material receiving piece is fixedly connected to the material receiving sliding seat.
[0013] The arrangement of the material receiving cylinder, the material receiving slide rail and the material receiving sliding seat enables the material receiving member to move forward and backward, so that the material receiving trough moves back and forth between the rolling thread assembly and the upper and lower material assemblies and below the discharge end of the material guide member.
[0014] In the above-mentioned automatic thread rolling machine for joints, the loading and unloading components also include a main driving cylinder arranged on the frame and a sub-driving cylinder one and a sub-driving cylinder two arranged in parallel on the main sliding seat. The main sliding seat is fixedly connected to the end of the piston rod of the main driving cylinder, the sub-sliding seat one is fixedly connected to the end of the piston rod of the sub-driving cylinder one, and the sub-sliding seat two is fixedly connected to the end of the piston rod of the sub-driving cylinder two.
[0015] The main driving cylinder is used to realize the sliding of the main sliding seat along the front-back direction, the auxiliary driving cylinder is used to realize the sliding of the auxiliary sliding seat 1 along the left-right direction, and the auxiliary driving cylinder 2 is used to realize the sliding of the auxiliary sliding seat 2 along the left-right direction.
[0016] In the above-mentioned automatic joint rolling machine, the gripper is a pneumatic two-finger gripper.
[0017] In the above-mentioned automatic thread rolling machine for joints, the thread rolling assembly includes a mounting base fixedly connected to the frame, an inner rolling wheel arranged on the mounting base and with the center line arranged left and right, and an outer rolling wheel located above the inner rolling wheel. The outer rolling wheel can move up and down, and the height of the material receiving trough in the vertical direction is the same as that of the inner rolling wheel.
[0018] In the above-mentioned automatic thread rolling machine for joints, the frame is also provided with a blanking plate whose front end is tilted downward relative to the rear end, and the blanking plate is located in front of the position between the thread rolling assembly and the upper and lower assembly.
[0019] After the hand grips the joint that has been rolled, the main sliding seat slides forward to move the hand gripper to the upper rear end of the unloading plate, and then the hand gripper releases the joint that has been rolled so that it falls onto the unloading plate and automatically falls into the receiving hopper.
[0020] Compared with the prior art, the automatic joint rolling machine can realize automatic loading and unloading of joints during joint rolling by means of the material guide, the material receiving member with a material receiving groove, and the setting of the upper and lower material components, thereby improving production efficiency.

[0033] Among them, Figure 1-Figure 4As shown, the material receiving member 4 is arranged in a long block shape along the front-back direction, and the material receiving groove 4a is located at the front end of the material receiving member 4, and the shape of the material receiving groove 4a is adapted to the joint 30.

Furthermore, a loading and unloading slide rail is provided on the frame 1, the main sliding seat 10 is connected to the loading and unloading slide rail, parallel auxiliary slide rails 1 and 2 are fixed on the main sliding seat 10, auxiliary sliding seat 1 11 is connected to auxiliary slide rail 1, auxiliary sliding seat 2 12 is connected to auxiliary slide rail 2, the loading and unloading assembly 5 also includes a main driving cylinder 15 arranged on the frame 1 and auxiliary driving cylinder 1 16 and auxiliary driving cylinder 2 17 arranged in parallel on the main sliding seat 10, the main sliding seat 10 is fixedly connected to the piston rod end of the main driving cylinder 15, the auxiliary sliding seat 1 11 is fixedly connected to the piston rod end of the auxiliary driving cylinder 16, and the auxiliary sliding seat 2 12 is fixedly connected to the piston rod end of the auxiliary driving cylinder 2 17.
[0035] In this embodiment, if Figure 7 and Figure 8As shown, the rolling assembly 2 includes a mounting base 18 fixedly connected to the frame 1, an inner rolling wheel 19 arranged on the mounting base 18 and with the center line arranged left and right, and an outer rolling wheel 20 located above the inner rolling wheel 19. The outer rolling wheel 20 can move up and down, and the height of the material receiving trough 4a in the vertical direction is the same as that of the inner rolling wheel 19. Specifically, the mounting base 18 is a rectangular frame, and two vertically arranged guide rails 21 are fixedly connected to the inner side of the mounting base 18, and a support block 22 is fixedly connected to the bottom inner side of the frame. An inner rolling shaft 23 is rotatably arranged on the support block 22, and the centerline height of the push rod 13 is the same as the centerline height of the inner rolling shaft 23. The inner rolling wheel 19 is fixedly connected to the right end of the inner rolling shaft 23. A motor base 24 is also fixedly connected to the frame 1, and an inner rolling drive motor 25 is fixed on the motor base 24.

[0036] When in use, the feed end of the guide member 3 is connected to the vibrator, and the vibrator sequentially introduces the joint 30 into the guide member 3 with the center line set to the left and the end with a larger outer diameter facing the left. Initially, the material receiving member 4 is in a state where the material receiving trough 4a is located below the material discharging end of the guide member 3, and the push rod 13 is in a position where the center line is colinear with the center line of the inner rolling shaft 23. The joint 30 falls from the guide member 3 into the material receiving trough 4a, and then the piston rod of the material receiving cylinder 8 pushes out and drives the material receiving member 4 to slide forward, so that the material receiving trough 4a moves to between the rolling assembly 2 and the upper and lower material assembly 5, and then the piston rod of the auxiliary driving cylinder 16 pushes out and drives the push rod 13 to extend and insert the end with a smaller outer diameter of the joint 30, and the push rod 13 will push the joint 30 out of the material receiving trough 4a and make the end with a larger outer diameter be sleeved outside the inner rolling gear 19. When the push rod 13 pushes the joint 30 onto the inner rolling cone 19, the receiving member 4 is reset to the initial position driven by the receiving cylinder 8. Then, the lifting motor 28 drives the vertical sliding seat 27 to move downward to make the outer rolling cone 20 approach the inner rolling cone 19. When the outer rolling cone 20 contacts the outer wall of the end with a larger outer diameter of the joint 30, since both the outer rolling cone 20 and the inner rolling cone 19 are rotating, the joint 30 and the push rod 13 are also rotated together under the action of friction, and as the outer rolling cone 20 gradually descends, the teeth are rolled on the end with a larger outer diameter of the joint 30.
[0037] After the rolling is completed, the outer rolling cone 20 is reset upward, and the push rod 13 is reset to the right. Then, the main driving cylinder 15 drives the main sliding seat 10 to move rightward to switch to the setting where the auxiliary sliding seat 12 is opposite to the inner rolling cone 19, and then the auxiliary driving cylinder 17 drives the hand claw 14 to move leftward and clamp the rolled joint 30 and remove it from the inner rolling cone 19. In practice, a blanking plate with a front end tilted downward relative to the rear end can be set on the frame 1. The blanking plate is located in front of the position between the rolling assembly 2 and the upper and lower assembly 5. After the hand claw 14 clamps the rolled joint 30, the main sliding seat 10 slides forward to move the hand claw 14 to the upper rear end of the blanking plate, and then the hand claw 14 releases the rolled joint 30 so that it falls into the blanking plate and automatically falls into the receiving hopper.
[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
