DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0034] Combine Figure 1 and Figure 2 As shown, a fully automatic pulley hole finishing device includes a workpiece introducing mechanism, a workpiece transferring mechanism 200, a workpiece advancing mechanism 300, a hole finishing mechanism 400 and a workpiece exporting mechanism;

[0035] Combine Figure 2 and Figure 3 As shown, the workpiece introduction mechanism includes an inclined main conveying rail 110, a first branch conveying rail 112, a second branch conveying rail 111 and a guide mechanism 120 arranged at the connection between the main conveying rail 110 and the two branch conveying rails. The first branch conveying rail 112 and the main conveying rail 110 are arranged on the same track and are connected. The second branch conveying rail 111 is arranged on one side of the first branch conveying rail 112 and is connected to the main conveying rail 110 through a horizontal connecting channel 113. The guide mechanism 120 includes a first baffle 121 that is lifted and connected above the connecting channel 113, a second baffle 122 that is telescopically connected at the connection between the connecting channel 113 and the main conveying rail 110, and a push rod 123. The push rod 123 is telescopically connected to the main conveying rail 110 on the side corresponding to the connecting channel 113. The main conveying rail 110 and the guide mechanism 120 are located outside the frame.

[0036] In the above structure, the pulley blanks to be processed are arranged on the main conveying rail 110. Since the main conveying rail 110 has a certain inclination, the pulley blanks maintain a tendency to move toward the first branch conveying rail 112 under the action of their own weight; when the first baffle 121 is raised and the second baffle 122 is extended, the connection between the first branch conveying rail 112 and the main conveying rail 110 is opened, and the second baffle 122 closes the connecting channel 113, and the pulley blanks are displaced forward along the inclination direction of the first branch conveying rail 112 and accumulated; when the first baffle 121 falls and the second baffle 122 retracts, the connection between the first branch conveying rail 112 and the main conveying rail 110 is closed, and the connecting channel 113 is in an open state, and the push rod 123 is extended and retracted once to push a workpiece toward the second branch conveying rail 111. The workpiece is displaced forward along the inclination direction of the second branch conveying rail 111 and accumulated;

[0037] It should be noted that initially, the pulley blank is placed in a storage bin and is introduced into the main conveyor rail through a lifting machine. After the pulley blank enters the main conveyor rail, the guide mechanism and the induction probe cooperate to first input the pulley blank into the first branch conveyor rail until the rail is full, and then the second branch conveyor rail is fed, realizing fully automatic switching and feeding.

[0038] Combine Figure 2-5 As shown, the workpiece transfer mechanism 200 includes a main body respectively arranged on both sides of the first branch conveyor rail 112 and the second branch conveyor rail 111, the main body consists of a turntable 210 and a retractable fork rod 220 arranged on the turntable 210, the turntable 210 is rotatably connected to the frame, and a guide rail 230 is also provided on the frame in front of the turntable 210, and the front ends of the first branch conveyor rail 112 and the second branch conveyor rail 111 respectively have avoidance grooves 114 corresponding to the fork rod 220, the turntable 210 rotates 90° so that the fork rod 220 faces the avoidance groove 114, the fork rod 220 extends and inserts into the hole on the workpiece in the guide rail 230, and then the turntable 210 resets so that the fork rod 220 brings a workpiece to the front of the guide rail 230;

[0039] The workpiece advancing mechanism 300 includes a telescopic rod 310 disposed at the rear end of the guide rail 230. When the workpiece is lifted by the fork rod 220 to the front of the guide rail 230, the fork rod 220 retracts and the telescopic rod 310 extends to advance the workpiece along the guide rail 230.

[0040] Combine Figure 2-6As shown, the hole finishing mechanism 400 includes a limit seat 410, a drill rod and a drill rod driving mechanism. The limit seat 410 has a limit hole 411 corresponding to the workpiece, and the middle of the limit hole 411 is also provided with a through hole that penetrates the limit seat 410. One end of the guide rail 230 is connected to the limit hole 411, and the workpiece is pushed to the limit hole 411 along the guide rail 230 by the telescopic rod 310 for limiting. The drill rod driving mechanism includes a column 421 fixed on the frame, a column 421 and a drill rod driving mechanism. The upper clamp 422 and the lower clamp (not shown) are displaced up and down and are respectively located above and below the limit seat 410. Initially, the drill rod is clamped on the upper clamp 422 and inserted into the pulley hole that has been roughly machined on the workpiece. After being inserted to a certain depth, the upper clamp 422 is released, and then the lower clamp clamps the drill rod to pass through the bottom of the pulley hole, and the drill rod is pulled down to further finish the pulley hole. After the processing is completed, the lower clamp is released, and the upper clamp 422 re-clamps the drill rod to pull out and reset the drill rod.

[0041] Combine Figure 1 、 Figure 2 and Figure 6 As shown, the workpiece export mechanism includes a telescopic lever 510 and a workpiece export groove 520, which are symmetrically arranged on both sides of the limit seat 410 and staggered with the guide rail 230. When the workpiece is processed, the telescopic lever 510 is quickly extended and retracted, pushing the workpiece to bounce off the limit seat 410 and fall into the workpiece export groove 520 on the opposite side, and the workpiece export groove 520 exports the workpiece.

[0042] The working principle of the above structure is: the workpieces are arranged in sequence on the main conveyor rail 110, and enter the first branch conveyor rail 112 and the second branch conveyor rail 111 in two rows under the action of the main conveyor rail 110 and the guide mechanism 120 respectively. The two groups of workpiece transfer mechanisms 200 transfer the workpieces to the front end of the guide rail 230 in sequence, and then the workpieces are pushed into the corresponding limit seats 410 under the action of the workpiece pushing mechanism 300. The drill rod of the hole finishing mechanism 400 finishes the pulley hole on the workpiece under the relay action of the upper and lower clamps. After the processing is completed, the drill rod is reset, and then the telescopic lever 510 performs a rapid telescoping, and the pushed workpiece bounces off the limit seat 410 and falls into the opposite workpiece guide groove 520, and the workpiece guide groove 520 guides the workpiece out.

[0043] As can be seen from the above, the above structure can realize the double-station fully automatic and efficient finishing of the hole on the pulley blank, which can effectively improve the processing efficiency.
