Technical Field

[0001] This application relates to the technical field of mechanical assembly, and in particular to an automatic assembly line device for gun drills. Background Technology

[0002] In the field of machinery manufacturing, the development of automated assembly line technology has greatly improved production efficiency and product quality. The emergence of automated assembly lines has gradually replaced traditional manual assembly methods, enabling rapid and precise assembly of product components. Especially in the manufacturing of small mechanical products, the application of automated assembly lines can produce standardized products on a large scale, reducing errors and quality instability caused by human factors, and bringing higher economic benefits and market competitiveness to enterprises.

[0003] However, in the field of gun drill assembly, the assembly of various parts is mostly completed by workers' experience and manual operation. The testing and marking of gun drills are also mostly done manually. On the one hand, the accuracy of manual operation is greatly affected by experience, resulting in a low product qualification rate. On the other hand, a large number of operators are required, resulting in high labor costs and easy operational errors due to fatigue, leading to low assembly efficiency. Summary of the Invention

[0004] In order to improve product qualification rate, reduce labor costs and improve assembly efficiency, this application provides an automatic assembly line device for gun drills.

[0005] This application provides an automatic assembly line device for gun drills, which adopts the following technical solution: It includes a machine body, on which a conveyor line, a multi-station positioning and flipping component, an automatic feeding structure, a locking module, a comprehensive testing module, a laser marking module, a discharge module, and a control system are arranged; the conveyor line is sequentially divided along the assembly process into a gun drill semi-finished product feeding section, a shell front and rear cover assembly section, a chuck feeding section, a chuck locking section, a testing section, a marking section, and a finished product receiving section; the multi-station positioning and flipping component, the automatic feeding structure, the locking module, the comprehensive testing module, the laser marking module, and the discharge module are sequentially arranged along the functional sections of the conveyor line, and are all electrically connected to the control system via shielded cables.

[0006] By adopting the above technical solutions, the entire process of gun drilling, from semi-finished product feeding to finished product collection, is automated, reducing efficiency losses caused by traditional manual handling, improving product qualification rate, reducing labor costs, and increasing assembly efficiency.

[0007] Preferably, the automatic feeding structure includes a front and rear cover feeder, a front and rear cover screw feeder, a chuck feeder, and a chuck screw feeder. The front and rear cover feeder is used to feed the pre-assembled gun drill semi-finished product (shell and front and rear cover) into the gun drill semi-finished product feeding section. The front and rear cover screw feeder is used to feed screws into the front and rear cover assembly section. The chuck feeder is used to feed finished chucks into the chuck feeding section. The chuck screw feeder is used to feed screws into the chuck fastening section. The multi-station positioning and flipping component and the fastening module cooperate to complete the gun drill assembly in the front and rear cover assembly section and the chuck fastening section, respectively.

[0008] By adopting the above technical solution, the automatic feeding structure is subdivided into four types of special feeding machines according to material type. It can provide directional supply for the semi-finished products of the front and rear covers of the shell and their corresponding screws, chucks and chuck screws, so as to avoid the risk of misassembly caused by mixing different materials. At the same time, through the collaboration of the multi-station positioning and flipping components and the locking module, the corresponding assembly process is accurately completed in specific sections, which shortens the process connection time of the assembly of the front and rear covers of the shell and the locking of the chucks, improves the accuracy of material supply, and effectively reduces the assembly scrap rate caused by material supply deviation.

[0009] Preferably, both the front and rear cover screw feeder and the collet screw feeder include a rotating disk and a screw screening channel. The rotating disk is used to stack screws, and multiple guide plates are provided inside the rotating disk. The multiple guide plates are evenly distributed around the circumference of the rotating disk to assist the screws in the rotating disk to enter the screw screening channel. The screw screening channel extends axially into the rotating disk. The end of the screw screening channel away from the rotating disk is connected to the fastening module through a screw pipeline. The fastening module is used to automatically pick up the screened screws and complete the screw pressing and fastening action.

[0010] By adopting the above technical solution, the screw feeder for the front and rear covers of the outer shell realizes the sorting of screws from disorder to order through the rotating disc, and then the screw pipeline and the fastening module work together to complete the automatic screw picking and tightening work, which solves the problems of disordered screw arrangement, manual reliance on specification screening and large conveying and positioning deviation in traditional manual feeding.

[0011] Preferably, the fastening module includes two sets of screw fastening modules and one set of chuck fastening modules. One set of screw fastening modules is disposed in the front and rear cover assembly section of the housing and is used to complete the assembly of screws on the housing and the front and rear covers. The other set of screw fastening modules and the chuck fastening module are integrated in the chuck fastening section and are used to mount the chuck onto the semi-finished gun drill and complete the assembly of screws on the chuck.

[0012] By adopting the above technical solution, one set of screw fastening modules focuses on the assembly of screws for the front and rear covers of the housing, while another set of screw fastening modules and chuck fastening modules are integrated in the chuck fastening section to work together to complete the installation of the chuck and the assembly of the chuck screws. This simplifies the process flow of chuck assembly, realizes functional zoning and specialized operation, avoids the efficiency loss caused by frequent switching of functions of a single fastening device, improves the connection efficiency of chuck and screw assembly, and adapts to the needs of multi-process assembly of gun drills.

[0013] Preferably, the chuck feeder includes a buffer belt and a chuck loading and conveying module. The end of the buffer belt is connected to the chuck loading belt. The chuck loading and conveying module includes a transverse drive component and a longitudinal drive component. The longitudinal drive component and a set of screw fastening modules are vertically arranged side by side on the transverse drive component. The chuck fastening module is arranged on the longitudinal drive component. The transverse drive component and the longitudinal drive component slide together to drive the chuck fastening module to slide longitudinally and laterally, thereby tightening the chuck from the buffer belt onto the semi-finished gun drill.

[0014] By adopting the above technical solution, the chuck feeder achieves orderly storage and transportation of chucks through the buffer belt and the chuck loading belt. The horizontal and vertical drive components of the chuck loading and handling module cooperate to drive the chuck locking module to achieve bidirectional sliding. The vertical drive component and a set of screw locking modules are arranged vertically side by side, allowing the chuck handling and screw locking actions to be promoted in tandem. This shortens the transportation path of the chuck from the buffer belt to the semi-finished gun drill, avoids waiting time between processes, and ensures accurate chuck installation and positioning by horizontal and vertical sliding. This solves the problems of inaccurate positioning and low assembly efficiency of traditional chuck handling and ensures the assembly accuracy of the chuck and the semi-finished gun drill.

[0015] Preferably, the screw fastening module includes a first intelligent electric screwdriver, a screw fastening cylinder, a screw suction tube, a first negative pressure component, a clamping inlet, and a screwdriver bit. The clamping inlet is connected to the screw pipeline, and a T-junction is formed between the clamping inlet, the screw suction tube, and the screwdriver bit. The first negative pressure component is connected to the other end of the screw suction tube and is used to allow the screw in the clamping inlet to enter the screwdriver bit. The first intelligent electric screwdriver is used to provide the power for tightening the screw, and the screw fastening cylinder is used to drive the first intelligent electric screwdriver and the screwdriver bit to move up and down and complete the screw pressing and locking action.

[0016] By adopting the above technical solution, the screw fastening module uses a three-way structure formed by the clamping inlet, the screw suction tube, and the screwdriver bit, in conjunction with the first negative pressure component, to achieve automatic screw adsorption and guidance, ensuring that the screw accurately enters the screwdriver bit; the first intelligent electric screwdriver provides stable tightening power, and the screw fastening cylinder drives the electric screwdriver and the bit to move up and down, completing the screw pressing and locking action. No manual intervention is required throughout the process, solving the problems of manual screw placement, inaccurate alignment, and unstable torque in traditional screw fastening.

[0017] Preferably, the chuck locking module includes a second intelligent electric screwdriver, a chuck locking cylinder, a chuck negative pressure tube, a second negative pressure component, and a chuck bit. One end of the chuck negative pressure tube is connected to the chuck bit, and the other end of the chuck negative pressure tube is connected to the second negative pressure component. The second negative pressure component is used to attract the chuck to the bottom of the chuck bit. The second intelligent electric screwdriver is used to provide the power to tighten the chuck. The chuck locking cylinder is used to drive the second intelligent electric screwdriver and the chuck bit to move up and down and complete the pressing and locking action of the chuck.

[0018] By adopting the above technical solution, the chuck locking module cooperates with the second negative pressure component through the chuck negative pressure tube to achieve stable adsorption of the chuck at the bottom of the chuck bit, avoiding the chuck from falling or shifting during transportation and installation. The second intelligent electric screwdriver provides tightening power adapted to the installation of the chuck, and the chuck locking cylinder drives the electric screwdriver and bit to move up and down, accurately completing the pressing and locking of the chuck.

[0019] Preferably, the multi-station positioning and flipping assembly includes a positioning module, which includes a first sliding platform, a second sliding platform, a servo drive assembly, and a pneumatic positioning fixture. The first sliding platform is disposed on the second sliding platform, and the second sliding platform is provided with a drive cylinder that drives the first sliding platform to reciprocate in the vertical direction. The pneumatic positioning fixture is disposed on the side of the first sliding platform near the front and rear cover assembly section of the outer shell. The servo drive assembly includes a servo motor and a ball screw. The servo motor is fixed on the machine body. One end of the ball screw is connected to the output shaft of the servo motor through a coupling, and the other end is fixed through a bearing seat. The length direction of the ball screw is arranged along the length direction of the machine body, and the ball screw passes through the second sliding platform.

[0020] By adopting the above technical solution, the positioning module uses the cooperation of the first sliding platform and the second sliding platform to drive the cylinder to achieve vertical sliding of the first sliding platform. The servo drive component drives the second sliding platform to move horizontally through the servo motor, ball screw and screw nut. The dual sliding structure allows the pneumatic positioning fixture to achieve multi-directional position adjustment, adapting to gun drill semi-finished products of different sizes. The pneumatic positioning fixture can stably hold the semi-finished products. The high precision of the servo drive ensures that the positioning deviation is extremely small, solving the problems of poor adaptability and low positioning accuracy of traditional positioning mechanisms.

[0021] Preferably, the multi-station positioning and flipping assembly further includes a positioning and flipping component, which includes a flipping base, a rotary cylinder, a clamping arm, and a clamping cylinder. The rotary cylinder is installed on the side of the flipping base, and the output shaft of the rotary cylinder is connected to the flipping base. The rotary cylinder is used to drive the flipping base to flip. The top of the flipping base has a groove for placing the gun drill semi-finished product. The clamping cylinder is embedded in the flipping base, and the piston rod of the clamping cylinder is connected to the clamping arm. After the gun drill semi-finished product is placed in the groove, the bottom of the clamping arm is used to abut against the upper surface of the gun drill semi-finished product, so that the gun drill semi-finished product is kept embedded in the groove.

[0022] By adopting the above technical solution, the rotating base is driven to rotate by a rotary cylinder. The angle of the positioning and rotating part can be adjusted according to the assembly requirements, so that the assembly surface is always in a state that is easy to operate. This solves the problem of low efficiency and reliance on manual adjustment of workpiece angle in traditional assembly. The groove on the top of the rotating base cooperates with the clamping arm driven by the clamping cylinder to stably fix the gun drill semi-finished product in the groove, preventing the workpiece from shifting or falling during the rotation process. The clamping arm abuts against the upper surface of the semi-finished product, which not only ensures the fixing effect, but also does not damage the surface of the workpiece.

[0023] Preferably, the discharge module is located at the end of the conveyor line. The discharge module includes a receiving belt, a good product belt, and an NG belt. One end of the receiving belt receives the laser marking module. The good product belt and the NG belt are arranged parallel to each other at the other end of the receiving belt. The good product belt, the NG belt, and the receiving belt have the same transport direction. An electric slide is provided at the bottom of the receiving belt. The electric slide is used to drive the receiving belt to slide back and forth between the good product belt and the NG belt in a direction perpendicular to the transport direction.

[0024] By adopting the above technical solution, the combination of receiving belt, good product belt and NG belt can realize the classified transportation of qualified and unqualified products. The electric slide at the bottom of the receiving belt drives the receiving belt to slide back and forth along the direction perpendicular to the conveying direction, which can accurately guide the finished products to the good product belt or NG belt. There is no need for manual sorting, which avoids unqualified products from being mixed into the finished products. At the same time, classified transportation makes the collection of finished products and the handling of NG products more organized, and improves the efficiency of subsequent packaging and maintenance.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1.
