Description

Technical Field

[0001] The utility model belongs to the technical field of pipe threading equipment design, in particular to a novel automatic pipe threading equipment. Background Art

[0002] In industrial production, the fields of thermal energy, construction, etc. need to insert round rod objects into round tube-shaped workpieces, which requires a new type of automatic pipe threading equipment. The existing pipe threading equipment lacks internal linkage and requires multiple power sources to realize the feeding process of round tubes and round rods. The production cost is high, the feeding process is cumbersome, and the degree of automation of the device is low. Utility Model Content

[0003] The purpose of the utility model is to provide a novel automatic pipe threading device to solve the problems existing in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A novel automatic pipe threading equipment comprises a pushing device, a transfer device is arranged at the rear of the pushing device, and a loading device is arranged in front of the transfer device; the transfer device comprises two symmetrically arranged brackets, a transmission shaft is rotatably arranged on the top of the bracket, a conveyor belt is arranged between the transmission shafts, a number of clamping blocks are evenly arranged on the conveyor belt, a driven wheel is arranged at the front end of the transmission shaft, a cam is arranged at the bottom of the driven wheel, and a motor is installed behind the cam; the loading device comprises a first pulley, a second pulley is arranged above the first pulley, a belt is arranged between the first pulley and the second pulley, a feeding roller is arranged in the middle of the second pulley, a feeding trough is arranged on the feeding roller, two fixing frames are symmetrically arranged at the front and rear ends of the feeding roller, and a storage frame is arranged on one side of the feeding roller.

[0006] Furthermore: the pushing device includes a support seat, an electric telescopic rod is installed on the top of the support seat, a push rod is arranged at the output end of the electric telescopic rod, a blanking plate is arranged behind the push rod, and a limit position frame is fixedly arranged at the bottom of the blanking plate.

[0007] Furthermore: the cross section of the limiting frame is U-shaped, and the limiting frame and the blanking plate are integrally formed.

[0008] Furthermore: the cam is connected to the bracket bearing, and the motor is connected to the bracket bolts.

[0009] Furthermore: the feed roller is connected to the fixed frame bearing, and the feed trough is U-shaped.

[0010] Furthermore: the first pulley is key-connected to the cam.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The bracket supports the motor to drive the cam to rotate. The cam intermittently toggles the driven wheel, driving the coaxial transmission shaft to rotate intermittently, so that the conveyor belt moves a certain distance and then pauses for a moment and continues to move, driving the round tube on the clamp block to move synchronously and intermittently. During the rotation of the cam, the first pulley is driven to rotate, and the first pulley drives the second pulley to rotate through the belt, so that the feeding roller rotates counterclockwise under the support of the fixed frame. During this process, the feeding trough rotates in a circle. Whenever the feeding trough moves to the bottom of the storage frame, a round rod falls into the feeding trough, and the remaining round rods continue to stay in the storage frame. The feeding roller drives the round rod to move until the round rod falls onto the unloading plate under the action of gravity and finally rolls into the limit frame. At this time, the cam is idling and does not toggle the driven wheel. The round tube on the clamp block is in a stationary state. The support seat supports the electric telescopic rod to retract, driving the push rod to move backward, pushing the round rod in the limit frame into the round tube, realizing the automatic tube threading process. The design of the cam toggling the driven wheel to drive the conveyor belt to move makes the round tube pause intermittently, which is convenient for leaving time for aligning the round rod, making the tube threading more accurate.

[0013] 2. By setting the first pulley on the cam, the motor can drive the two raw materials, round tubes and round rods, to move at the same time, thus improving the linkage of the device and reducing production costs;

[0014] 3. The design of feeding by rotating the feeding roller can stably feed the materials without fine positioning of the round rod, which simplifies the feeding process and improves the degree of automation of the device. BRIEF DESCRIPTION OF THE DRAWINGS
