[0002] There are many types of locks, and the gourd lock belongs to one of the major categories. The gourd lock is mainly applied to various door locks. It mainly includes: a lock body, a lock core, and a lock head. Among them, the lock body is generally made of metal. The lock body of the gourd lock is generally a columnar structure, and the cross-section is in the shape of a gourd that is narrow at the top and wide at the bottom. The lock body can be divided into a narrow lock body and a wide lock body according to the width. A through hole for installing the lock core is provided on the wide lock body. At the same time, a slot is provided in the middle of the lock body. The slot runs through the wide lock body and part of the narrow lock body. The slot is used for installing the lock head. A number of pin holes communicating with the through hole are provided on the narrow lock body (see Figure 8 ). The raw material of the lock body is a metal straight rod with a cross-section in the shape of a gourd, and a lock body with a certain width is obtained through a cutting process. Since the shape of the gourd lock is a non-standard part and there are many processing procedures, the automation degree of the current equipment for processing this type of lock body is not high, and the production efficiency is low. Summary of the Invention

[0003] The present invention provides a device for processing the lock body of a gourd lock; it solves the problems of low automation degree and low production efficiency existing in the prior art.

The slot runs through the wide lock body and part of the narrow lock body; the specific slotting method can adopt existing cutting methods such as cutting disk rotary cutting and wire cutting;

[0007] A track groove, the track groove is linear and fixed in the front-back direction relative to the frame, and the length direction of the lock body is parallel to the track groove;

[0008] A handling mechanism, the handling mechanism includes: a first moving frame, the first moving frame can reciprocate back and forth along the distribution direction of the track groove, and the moving distance each time is fixed; a second moving frame, the second moving frame moves synchronously with the first moving frame, and at the same time, the second moving frame can reciprocate up and down relative to the first moving frame; the first moving frame and the second moving frame can be controlled to move by existing linear propulsion mechanisms, such as cylinders, linear motors, gear-rack mechanisms, etc.;

[0009] A fixture, the fixture is located on the upper side of the track groove, the number of the fixtures is several and they are evenly distributed along the front-back direction of the frame, the distance between adjacent fixtures is the same as the moving stroke of the first moving frame, and the handling mechanism can drive all the fixtures to move synchronously; the fixture can form clamping and limiting with the lock body only by its shape, and it is not necessary to have a clamping action;

[0010] A first drilling component, the drilling direction of the first drilling component is parallel to the axial direction of the lock body, and the first drilling component can drill a lock core hole penetrating the slot on the lock body, and the lock core hole is located in the wide lock body;

[0011] A drilling and tapping component, the drilling and tapping component can process positioning screw holes on the narrow lock body. The positioning screw holes avoid the lock core hole and the slot, and can sequentially perform drilling and tapping operations on the lock body;

[0012] A second drilling component, the drilling axis of the second drilling component is parallel to that of the first drilling component, and the second drilling component can process a stepped hole at each end of the lock core hole;

[0013] A third drilling component, which is used to process several pin holes on the narrow lock body. The pin holes communicate with and are perpendicular to the lock core hole;

[0014] A first transfer mechanism, the first transfer mechanism can be used to transfer the lock body. A first transfer mechanism is connected between the track groove and the first drilling component, a first transfer mechanism is also connected between the track groove and the second drilling component, and a first transfer mechanism is also connected between the track groove and the drilling and tapping component;

[0015] A second transfer mechanism, the second transfer mechanism can be used to transfer the lock body. A second transfer mechanism is connected between the track groove and the third drilling component;

[0016] The first transfer mechanism and the second transfer mechanism can specifically adopt mechanical structures such as a robotic arm or a moving slide;

[0017] The handling mechanism can drive the fixture to move up and down, front and back. The action modes of the fixture are successively clamping and fixing with the lock body downward, driving the lock body to move backward, separating from the lock body upward, and returning to the original position forward; the handling mechanism cycles according to the above action modes, and the fixture can drive the lock bodies on the conveying track to move backward step by step at equal distances;

[0018] The feeding mechanism can provide lock bodies to the grooving assembly. After the lock bodies are grooved, they are transferred into the track groove and then gradually transferred backward by the handling mechanism. After each cycle of the handling mechanism, there is a fixed pause time. During this pause time, the first transfer mechanism and the second transfer mechanism can transfer the lock bodies on the track groove to the first drilling assembly, the drilling and tapping assembly, the second drilling assembly, and the third drilling assembly. After the corresponding machining is completed, the first transfer mechanism and the second transfer mechanism can transfer the lock bodies back to the track groove. After the machining of the third drilling assembly is completed, the lock bodies can be directly discharged.

[0019] In summary, the present invention connects each drilling process in series through the handling mechanism and the track groove, enabling different lock bodies on the track groove to undergo a machining process simultaneously within one action cycle of the handling mechanism. The final result is that for each action cycle of the handling mechanism, one lock body completes all machining processes. The present invention has a high degree of automation, and the production efficiency is determined by the slowest single station in the machining time. Therefore, there is almost no unnecessary idle running time during the production process, and the overall production efficiency is high.

[0020] Further, the feeding mechanism includes: a first moving seat and a first clamping mechanism. The moving direction of the first moving seat is parallel to the track groove. The first clamping mechanism is fixed on the first moving seat. The first clamping mechanism includes a first clamping piece and a second clamping piece that can be clamped to each other, and the first clamping mechanism is used to clamp the lock body. The grooving assembly includes a second clamping mechanism, a third moving seat, and a cutting module. The cutting module is fixed on the third moving seat. The moving direction of the third moving seat is perpendicular to that of the first moving seat. The cutting module is provided with a cutting blade and a grooving blade. The first moving seat can drive the first clamping mechanism and the lock body thereon to move towards the second clamping mechanism until the lock body is partially fed into the second clamping mechanism. After the second clamping mechanism clamps and fixes the lock body, the first clamping mechanism releases, and the first moving seat returns to its original position. The third moving seat pushes the cutting module close to the lock body until the cutting blade completes the cutting process of the lock body, and at the same time, the grooving blade completes the grooving process of the lock body. After the machining of the lock body is completed, the second clamping mechanism releases and waits for the next cycle, and the lock body in the second clamping mechanism will be pushed out in the next cycle. The present invention uses a clamping and reciprocating feeding method for feeding. This feeding method is suitable for handling long rod-shaped items. Combined with the cutting module on the grooving assembly, the metal rod-shaped semi-finished products can be directly processed into semi-finished lock bodies with grooves. This enables the present invention to directly use straight rod-shaped metal strips as the feeding semi-finished products, improving production efficiency.

[0021] Further, each time the feeding mechanism advances, the lock body in the second clamping mechanism will be pushed backward by a fixed distance. A guiding groove is connected to the rear side of the second clamping mechanism. The guiding groove can receive the lock body dropped from the second clamping mechanism. The side wall of the guiding groove near the wide lock body side is gradually elevated. As the lock body moves backward along the guiding groove, the wide lock body will flip upward, and finally form a posture where the narrow lock body is vertically downward; a fourth moving seat is provided at the rear side of the guiding groove. A guiding groove segment is provided on the fourth moving seat. The fourth moving seat can drive the guiding groove segment to move to dock with the rear end of the guiding groove, and can also drive the guiding groove segment to move to dock with the front end of the track groove. The lock bodies in the guiding groove move backward in a gradually butted manner, and the fixture on the handling mechanism can only handle one lock body at a time. Therefore, it is necessary to transport the originally butted lock bodies to the track groove one by one through the guiding groove segment.

[0022] Further, the groove profile of the track groove is the same as the cross-section of the lock body, and the posture of the lock body on the track groove is that the narrow lock body is vertically downward; several notches are provided on the track groove, and the notches are used to install the first transfer mechanism and the second transfer mechanism;

[0026] An avoidance groove, and the opening of the avoidance groove faces upward and is vertically opened on the upper sides of both the fixed clamping plate and the moving clamping plate. The bottom of the avoidance groove is set lower than the lowest point of the lock body;

[0027] A moving pin, and the moving axial direction of the moving pin is the same as that of the moving clamping plate. The width of the moving pin is the same as the width of the slot on the lock body;

[0028] One action cycle of the fixture can move the lock body in the track groove between the fixed clamping plate and the moving clamping plate, and then the moving pin moves towards the lock body until it forms a snap fit with the slot on it, so as to prevent the lock body from moving back and forth. Then the moving clamping plate clamps the lock body, and the second moving seat drives the whole to move towards the first drilling component or the second drilling component. After the lock body is machined, the first transfer mechanism returns to the notch of the track groove, and the moving pin and the moving clamping plate move in the reverse direction to separate from the lock body. The first transfer mechanism can better fix the lock body, and at the same time has a higher positioning accuracy for the lock body, facilitating the lock body to complete machining with high precision.

[0029] Furthermore, the first drilling assembly includes two opposing first drilling machines and two groups of first slides, the drill bit axis of the first drilling machine is parallel to the axis of the track groove, the first drilling machine is fixed on the first slide, and the moving direction of the first slide is parallel to the axis of the track groove; the drilling and tapping assembly includes a second drilling machine, a tapping machine and a second slide, the second slide is parallel to the moving direction of the first slide, the second drilling machine and the tapping machine are fixed on the second slide and the drill bits of both are axially facing the track groove; the second drilling assembly includes two opposing third drilling machines and two groups of third slides, the drill bit axis of the third drilling machine is parallel to the axis of the track groove, the third drilling machine is fixed on the third slide, and the moving direction of the third slide is parallel to the axis of the track groove, and the second drilling assembly also includes a polishing sheet, and the polishing sheet is a slot facing the locking body on the first transfer mechanism. The thickness of the polishing sheet is the same as that of the slotting sheet. After the lock body is drilled by the first drilling assembly, burrs will be generated on the slotting side wall. After the first transfer mechanism at the second drilling assembly drives the lock body to contact the polishing sheet, the burrs will be removed.

[0030] Further, the third drilling assembly includes: a third electric drill, the axial direction of the third electric drill is horizontal and perpendicular to the axial direction of the lock core hole, and the drill bit of the third electric drill faces the track groove;

A stepper motor capable of driving the positioning pin to rotate is provided on the frame. The strip-shaped groove is arranged facing the third electric drill. After the drilling is completed, the stepper motor drives the positioning pin to rotate several circles. The strip-shaped groove can prevent the third electric drill from damaging the positioning pin. At the same time, the strip-shaped groove can form a function similar to a reamer on the positioning pin. By rotating the positioning pin, the burrs generated by drilling can be removed.

[0039] Further, the second transfer mechanism includes a fifth moving seat and the segmented track grooves thereon. The fifth moving seat can drive the segmented track grooves to move to dock with the track groove, or can also drive the segmented track grooves to move to face the positioning pin.

The groove body profile of the track groove segment is the same as the track groove, and the lock body can be moved into the track groove segment by the fixture.

[0088] See Figure 1 The third drilling assembly needs to drill more holes, so it takes more machining time. In order to make the overall production rate higher, two groups of third drilling assemblies are arranged side by side, and the second transfer mechanism works once every two cycles of the transport mechanism. That is, the transport mechanism cycles twice, and two groups of third drilling assemblies complete one machining, which makes the time consumed by the equipment to produce a single lock body shorter.

[0089] If the moving base in this embodiment is not specifically specified, the movement is controlled by a linear motor.

[0090] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
