The avoidance cylinder 9b can enable the detection head 9a and the sensor 6a to be located in the welding station or to be far away from the welding station, when the detection head 9a and the sensor 6a are located in the welding station, the detection head 9a can be depended on the outer side face of the edge opening 14a of the thin-wall drill cylinder 14, and the detection of the position of the outer side face of the cutter head welding operation section in the edge opening 14a of the thin-wall drill cylinder 14 is achieved; when the detection head 9a and the sensor 6a are far away from the welding station, the detection head 9a and the sensor 6a can be effectively protected, namely, the detection head 9a and the sensor 6a are prevented from being damaged by welding heat.
A flexible driving piece which can enable the detection head 9a and the side surface of the edge opening 14a of the thin-wall drill cylinder body 14 to be kept in a leaning state is arranged between the detection head 9a and the bottom plate 9 d. The flexible driving part is an air cylinder 9e, the input air pressure of the air cylinder 9e is adjusted to ensure that the detection head 9a can move along the outer side surface of the edge opening 14a of the thin-wall drill cylinder body 14 and move along the guide direction of the guide structure, and the detection head 9a always abuts against the outer side surface of the edge opening 14a of the thin-wall drill cylinder body 14. The drawings in the specification show that the air cylinder 9e is a translation air cylinder 9e with a guide structure, so that the guide structure and the air cylinder 9e are combined together, and the advantages of compact structure and low manufacturing cost are achieved. According to the actual situation, the flexible driving member can also adopt a spring, one end of the spring is propped against the detection head 9a, and the other end of the spring is propped against the bottom plate 9 d.
The detection head 9a comprises a detection base 9a1 and a roller 9a2 rotatably connected with the detection base 9a 1; the outer side surface of the roller 9a2 can abut against the outer side surface of the rim 14a of the thin-wall drill cylinder 14, when the thin-wall drill cylinder 14 rotates, the thin-wall drill cylinder 14 drives the roller 9a2 to rotate, so that rolling friction is generated between the thin-wall drill cylinder 14 and the detection head 9a, the rotation stability of the thin-wall drill cylinder 14 is ensured, the abrasion loss of the detection head 9a is reduced, the jumping amplitude of the detection head 9a is reduced, and the service life and the detection precision of the detection head 9a are improved.
The first motor of the first tool bit position adjusting mechanism 8c in the tool bit holding device 8 and the displacement sensor 9c are electrically connected to the control circuit. The functions and advantages of each part are further explained by explaining the process of welding and processing a thin-wall drill by using the thin-wall drill welding machine.
The avoidance cylinder 9b is controlled to enable the detection head 9a to be located at the welding station, namely the detection head 9a is located right below the tool bit clamping device 8; under the action of the flexible driving piece, a roller 9a2 of the detection head 9a abuts against the outer side surface of a cutter head welding operation section in the edge opening 14a of the thin-wall drill cylinder body 14; preferably, the guiding direction of the guiding structure is parallel to the radial line of the outer side surface of the bead 14a of the thin-wall drill cylinder 14, and the roller 9a2 of the detecting head 9a abuts against the central line of the outer side surface of the cutter head welding operation section in the bead 14a of the thin-wall drill cylinder 14; the movement stroke of the detection head 9a measured in this way can accurately reflect the deviation distance between the outer side surface of the thin-walled drill cylinder body 14 and the outer side surface of the bead 14 a.
And controlling the indexing motor 5a to operate, wherein the indexing motor 5a drives the thin-wall drill cylinder body 14 to rotate. As shown in fig. 6 and 7, the outer side surface of the thin-wall drill cylinder body 14 is oval, so that the thin-wall drill cylinder body 14 can move the detection head 9a along the guiding direction of the guiding structure during the rotation process, and the displacement sensor 9c measures the moving stroke of the detection head 9 a.
The control circuit records the moving stroke of the detection head 9a when each tool bit welding section in the edge opening 14a of the thin-wall drill cylinder body 14 is positioned on the welding station. Assuming that the number of diamond tips in the thin-wall drill is 4, the moving stroke L1 of the detection head 9a when the first tip welding section is located at the welding station, the moving stroke L2 of the detection head 9a when the second tip welding section is located at the welding station, the moving stroke L3 of the detection head 9a when the third tip welding section is located at the welding station, and the moving stroke L4 of the detection head 9a when the fourth tip welding section is located at the welding station. The position of one side surface of the diamond tool bit clamped by the tool bit clamping device 8 corresponds to the position of the outer side surface of a tool bit welding operation section in the bead 14a of the thin-wall drill cylinder body 14 by operating the first tool bit position adjusting mechanism 8 c; i.e. relative position between the first diamond tip and the thin-walled drill body 14.
When welding a second diamond tool bit, the control circuit automatically controls the operation of the first motor according to the difference between L2 and L1, and the first motor enables the tool bit clamp 8a to move for a distance corresponding to the difference along the thickness direction of the diamond tool bit, so that the position of one side surface of the diamond tool bit clamped by the tool bit clamping device 8 relative to the position of the outer side surface of the welding section of the second tool bit in the bead 14a of the thin-wall drill cylinder body 14 also meets the design requirement. When each diamond tool bit is welded, the control circuit controls the first motor to operate according to the corresponding difference value, so that the position of one side face of each diamond tool bit clamped by the tool bit clamping device 8 corresponds to the position of the outer side face of the tool bit welding section in the bead 14a of the thin-wall drill cylinder body 14, and the position of the outer side face of the tool bit welding section corresponds to the design requirement.
