Description

Technical Field

[0044] Combination Figure 1-15 As shown, the processing process and principle of the present invention will be described step by step below. First, Fig.15As shown in the schematic diagram of the lock body workpiece, the workpiece is provided with a first lock core hole 100, a second lock core hole 101, a lock tongue notch 200, a first pin hole 300, a second pin hole 301, and a mounting hole 400.

[0045] first Figure 3 The feeding fixture 23 in the middle clamps the long strip of profile, and is driven by the servo slide connected to the feeding fixture 23. The long strip of profile will enter the first double-jaw pneumatic chuck 24 until the front end face of the long strip of profile is against the baffle plate 211. The cutting head 22 drives the first cutting blade 211 to complete the cutting. Then the first double-jaw pneumatic chuck 24 is driven by the servo slide connected to it to move forward, so that the cut workpiece passes through the drawing tool 2, and after obtaining the required length, it continues to move forward and runs to the front of the first first robot arm 5. The whole process of unloading is completed. In addition to unloading, the total length of the workpiece is also processed.

[0046] In the next step, the workpiece is sent to the first group of lock core hole drilling mechanisms 31 through the first robotic arm 5 to complete the drilling of the first lock core hole 100, and then after the end face is turned by the second robotic arm 6, it is sent to the second group of lock core hole drilling mechanisms 31 to complete the drilling of the second lock core hole 101. Among them, the lock core hole drilling mechanism 31 adopts a stepped drill bit to drill from both ends, mainly considering that the length of the workpiece is relatively long. If drilling from one end, the verticality of the hole will be greatly affected.

[0047] In the next step, the workpiece enters the lock tongue groove cutting structure 32 to process the lock tongue groove 200. Since the length requirements of the first lock core hole 100 and the second lock core hole 101 are the control points of the processing, the size requirements of the lock tongue groove 200 are not high. For this reason, the workpiece end face is used as the reference point and is cut in two ways to ensure the length of the first lock core hole 100 and the second lock core hole 101.

[0048] Next, the workpiece is sent to the lock core hole reaming mechanism 36, and a reamer is correspondingly installed on the lock core hole reaming machine head 361 to ream through the first lock core hole 100 and the second lock core hole 101 at one time to ensure the concentricity of the two holes, and at the same time remove the burrs remaining when processing the lock tongue notch 200 in the previous step.

[0049] Next, the workpiece is sent to the first group of pin hole drilling mechanisms 33 to complete the drilling of the first pin hole 300 , and then the workpiece is sent to the second group of pin hole drilling mechanisms 33 after the end face is turned by the second robot arm 6 to complete the drilling of the second pin hole 301 .

[0050] Next, the workpiece is sent to the pin hole expanding mechanism 37. Many pins need step limits when they are installed. The pin hole expanding mechanism 37 mainly expands the first pin hole 300 and the second pin hole 301 processed in the previous process to obtain limit steps.

[0051] Next, the workpiece is sent to the mounting hole drilling mechanism 34 to complete the drilling process of the mounting hole 400. During the drilling process, the lock core hole deburring head 38 installed on the side of the mechanism synchronously performs burr removal on the first lock core hole 100 and the second lock core hole 101 again. The reason is that during the processing of the first pin hole 300 and the second pin hole 301, burrs will be turned outward into the first lock core hole 100 and the second lock core hole 101.

[0052] Next, the workpiece is sent to the mounting hole tapping mechanism 35. During the workpiece tapping process, the chamfering head 39 of the inner side of the lock core hole on the side of the mechanism will synchronously chamfer the two opposite ends of the first lock core hole 100 and the second lock core hole 101 to make the inner side surfaces of the lock tongue groove 200 as smooth as possible.

[0053] In the next step, until the previous step, the entire processing is completed, and the workpiece will also be sent to the top of the discharge hole 7 by the first robot arm 5 to complete the discharge.

[0054] The present invention proposes a fully automatic processing equipment for gourd lock core. The feed amount of each machine head is individually controlled by a servo motor to improve product precision. At the same time, a reaming mechanism is provided to remove burrs in the hole, improve assembly efficiency and product quality, and adopts a progressive workpiece transmission method to improve processing efficiency.

[0055] It should be understood that the exemplary embodiments described herein are illustrative rather than restrictive; although embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art should understand that various changes in form and details may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
