Description

Technical Field

[0001] The present invention relates to a tongue and cylinder automatic assembly machine, belonging to the field of lock assembly equipment. Background Art

[0002] As a common lock, the padlock is widely used. The assembly sequence of the padlock body is as follows: the tongue, the cylinder, and the lock beam.

[0039] Reference Figure 13 As shown, the first lock body fixture 4a and the second lock body fixture 4b have the same structure and principle, and the installation height of the two is the same, and they are located directly below the first bottom mounting plate 111 and the second bottom mounting plate 241; the first lock body fixture 4a includes: a base 41, a lifting block 42, a pressing cylinder 43, a top locking cylinder 44 fixed to the lifting block 42, and a fixing cylinder 45; the surface of the base 41 is provided with a plurality of guide holes 411; the interior of the base 41 is provided with a groove, and the groove is provided with a locking cylinder 45.

[0040] Reference Figure 4 As shown, a second lock tongue feed assembly 14b for backup is also installed on the first bottom mounting plate 111; the structure and principle of the second lock tongue feed assembly 14b are the same as those of the first lock tongue feed assembly 14a, and they are installed in a mirror image of each other.

[0041] Preferably, the second lock tongue feeding assembly 14 b is connected to a second lock tongue feeding tray 3 e for backup; the second lock tongue feeding tray 3 e is mounted and fixed on the frame 10 .

[0042] Combine Figure 1-13 The working process of the present invention is described in detail in two steps, namely the lock tongue assembly process and the lock core assembly process. The first lock body fixture 4a and the second lock body fixture 4b have exactly the same structure and move between the lock tongue assembly mechanism 1 and the lock core assembly mechanism 2 in an alternating cycle. That is, the present invention simultaneously completes the assembly of the lock tongue and the lock core on the first lock body fixture 4a and the second lock body fixture 4b. The following process will take the lock body assembly on the first lock body fixture 4a as an example.

[0043] The first step is to assemble the lock tongue. Figure 4 、 5, as shown in Figures 6, 7, and 13, first, the first locking tongue feeding tray 3a and the spring feeding tray 3b feed the first locking tongue feeding assembly 14a and the locking tongue spring feeding assembly 15 respectively. After the locking tongue enters the locking tongue feeding rail 142, the guiding boss 1421 will snap into the groove where the locking tongue docks with the lock core. After entering the loading groove 1411, the locking tongue groove will be engaged with the head of the limiting block 1413. This ensures that the locking tongue groove faces in one direction throughout the process. At the same time, the spring will enter the spring loading hole 1511 along the spring feeding through hole 1531. Then, the first lock body fixture 4a is in place, and the lock body is pushed into the Figure 13 lock body groove 422 shown, and the side of the lock body presses against the top lock cylinder 44. Then, the pushing pin 18, under the push of the push pin cylinder 17, passes through the material passing hole 161 and the through hole 1111 and enters the locking tongue hole of the lock body to position the lock body. Then Figure 13 the pressing cylinder 43 in presses against the lifting block 42 to press the lock body tightly against the bottom surface of the first bottom mounting plate 111. Subsequently, the push pin cylinder 17 returns. The spring feeding cylinder 152 pushes the spring feeding plate 1511 to send the spring to directly above the material passing hole 161. The push pin cylinder 17 drives the pushing pin 18 again to push the spring into the locking tongue hole of the lock body. Then the push pin cylinder 17 returns again. Then, the second pneumatic slide 6b operates to drive the locking tongue feeding plate 141 to send the locking tongue to directly above the material passing hole 161. Then the push pin cylinder 17 drives the pushing pin 18 to push the locking tongue again, and the limiting block 1413 that catches the locking tongue groove will retract under the action of the pushing spring 1414 to ensure that the locking tongue enters the lock body. After that Figure 13 the fixing cylinder 45 in drives the fixing rod 46 to press the locking tongue, and the pressing cylinder 43 unloads, completing the entire assembly operation.

[0044] In the second step, when assembling the lock core, the lock body that has completed the first-step assembly is still in the first lock body fixture 4a, and the fixing rod 46 continuously presses the locking tongue. The first lock body fixture 4a is pushed by the first pneumatic slide 6a to the lock core assembly mechanism 2. Combining Figure 8-13 , the lock core feeding tray 3c will continuously feed the lock core into the Figure 10 lock core groove 2221 shown, and the lock core pin feeding tray 3d will continuously feed the lock core pins into the Figure 12 pin loading holes 2311 shown. During assembly, the lifting table board 11 rises, and the third pneumatic slide 6c and the fifth pneumatic slide 6e start to operate. The horizontal push rod 216 pushes the lock body backward, making the back of the lock body closely abut against the Figure 13 pushing end of the top lock cylinder 44 shown. The sixth pneumatic slide 6f drives the loading block 222 to move forward to directly in front of the lock body, making the lock core in the lock core groove 2221 face the lock core hole on the lock body. Subsequently Figure 1The third pneumatic slide 6c and the fourth pneumatic slide 6d in the lock core are moved to drive the rotating push rod 215 to push the lock core in the lock core groove 2221 into the lock body, while keeping the flat head 2151 at the front end of the rotating push rod 215 inserted into the key slot of the lock core, and then Figure 12 The positioning cylinder 25 pushes the positioning pin 27 to be inserted into the lock core in the lock body to position the lock core, and then Figure 13 The pressing cylinder 43 pushes the lifting block 42, and the top surface of the lock body is pressed against the bottom surface of the second bottom mounting plate 241 to form a fixed position. Figure 12 The pin feeding cylinder 232 in the middle pushes the pin feeding plate 231 forward. When the pin carrying hole 2311 is facing the ejector pin through hole 2412, the lock core pin inside it automatically passes through the ejector pin through hole 2412 and falls into the lock body. Then the push cylinder 26 pushes the ejector pin 28, pushing the lock core pin into the lock body and locking it into the lock core. Figure 9 The stepper motor 214 in the lock body moves, driving the rotary push rod 215 to rotate the lock core, so that the lock core and the lock tongue are connected, and the lifting platform 211 is lowered so that the open end of the discharge bin 213 is aligned with the lock body groove 422, and then Figure 13 The fixed cylinder 45 in the middle is unloaded, and at the same time, the locking cylinder 44 pushes the assembled lock body into the discharge bin 213. At this point, the lock core is installed, which also means that the lock core and lock tongue of the entire lock body are assembled.

[0045] The invention provides an automatic assembly machine for a lock tongue and a lock core. A single assembly machine can simultaneously complete the assembly of the lock tongue and the lock core, replacing a traditional assembly method, reducing labor and improving efficiency.
