Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping machines, and in particular to a multi-position drilling and tapping integrated machine. Background Technology

[0002] Currently, drilling, reaming, and tapping of workpieces are performed separately by different equipment. These separate processes require transferring workpieces between different machines. Traditionally, after drilling, a batch of workpieces is moved to the reaming machine, and after reaming, the batch is moved to the tapping machine. This constant transfer between machines results in low processing efficiency and high costs. While some manufacturers now use gripper-type robotic arms to pick up and transfer workpieces to the next workstation, [the following text is incomplete and requires further context]. Gripping robotic arms are prone to pinching and scratching workpieces, damaging their appearance and reducing the yield rate. Furthermore, drilling, reaming, and tapping equipment are required to perform drilling, reaming, and tapping processes on workpieces separately. Most workpiece fixing mechanisms on the market use reference blocks and cylinder side-push structures to position the workpiece. However, after fixing the workpiece with reference blocks and cylinder side-push structures, lateral displacement is prone to occur during drilling, reaming, and tapping processes, resulting in reduced drilling, reaming, and tapping accuracy, thereby reducing the yield rate of workpiece processing.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. Its overall structural design integrates multiple different processing steps such as drilling, reaming, and tapping on the same equipment, avoiding the need for enterprises to purchase different processing equipment such as drilling equipment, reaming equipment, and tapping equipment separately, thereby reducing the processing cost of workpieces and avoiding the need to transfer workpieces between different processing equipment. This achieves the goal of improving workpiece processing efficiency and strong versatility. It has the advantages of high processing efficiency, high processing accuracy, and good processing effect. The magnetic suction handling mechanism uses an electrically controlled magnetic suction method to pick up workpieces instead of using a gripper cylinder to grip the workpieces, ensuring the integrity of the workpiece appearance and the high yield rate of the workpieces. This effectively solves the problems of low workpiece processing efficiency caused by the traditional use of gripper-type robotic arms to transfer workpieces between different equipment and the low yield rate of workpieces caused by the easy damage to the workpiece or scratches left on the workpiece surface when using gripper-type robotic arms.

[0016] 2. By sequentially equipping the drilling, reaming, and tapping stations with a first fixing component, a second fixing component, and a third fixing component, the workpiece is fixed. A loading reference component provides lateral reference positioning for the loaded workpiece, and a unloading reference component arranges and organizes the workpiece after tapping. This ensures high precision, good processing effect, and high yield in drilling, reaming, and tapping, thus solving the problem of poor precision and low yield caused by lateral displacement during processing in existing workpiece fixing mechanisms that use reference blocks and cylinder side-push structures for workpiece positioning.

[0017] 3. By installing a chip removal component on the machine base and below the positioning base, it can automatically remove and collect the waste chips generated by the workpiece during drilling, reaming and tapping, keeping the processing environment of each station clean so as not to affect the processing accuracy of each station. It also solves the problem that drilling equipment, reaming equipment and tapping equipment on the market do not have automatic chip removal function, which requires manual cleaning of waste chips.

[0018] 4. It expands the workpiece by means of the first and second expanding mechanisms, and taps the workpiece by means of the first and second tapping mechanisms, thereby improving the efficiency of expanding and tapping the workpiece. Attached Figure Description

The suction plate lifting drive device 671 is longitudinally mounted on the transport slide plate 66, and the magnetic suction plate 672 is mounted on the output end of the suction plate lifting drive device 671.

The fixing base 415 is mounted on the positioning base 2. The top of the fixing base 415 is recessed downward to provide a fixing groove 416. The bottom of the fixing groove 416 is provided with a first chip removal groove 417 for chip removal. The pad 411 is fixedly mounted on one side wall of the fixing groove 416.

The bottom of the top plate 412 facing the pad 411 is chamfered.

[0038] By adopting the above technical solution, when the workpiece is placed on each fixed component, the workpiece uses the limiting groove 418 of the pad 411 of each fixed component as a reference. The pad 411 provides a three-sided reference for the workpiece. The top plate translation drive device 414 pushes the pressure plate 413 to drive the top plate 412 to press the workpiece on the pad 411 to achieve limiting and fixing of the workpiece. This makes the workpiece limiting and fixing stable and has a good fixing effect. When the chamfered slope of the top plate 412 moves, it can push the waste chips onto the first chip discharge groove 417 for automatic waste chip unloading and recycling. This avoids the waste chips accumulating on the limiting groove 418, which would cause the workpiece to be placed incorrectly and affect the accurate positioning of drilling, reaming and tapping of the workpiece.

The feeding reference push plate 33 is installed on the output end of the first reference push plate translation drive device 34.

[0041] By adopting the above technical solution, when the workpiece is placed on the loading reference base 35, the first loading side limiting plate 31 and the second loading side limiting plate 32 limit the workpiece on both sides.

The tap lateral movement assembly 916 is mounted on the machine base 1, the tapping spindle box 912 is mounted on the tap lateral movement assembly 916, the tap release drive device 913 and the tapping spindle 911 are mounted at the bottom of the tapping spindle box 912, and the tap release drive device 913 and the tapping spindle 911 are drivenly connected. The tap 910 is movably mounted inside the tapping spindle 911, the tap rotation drive device 914 is mounted at the top of the tapping spindle box 912, and the tap rotation drive device 914 is drivenly connected to the tapping spindle 911 through the third synchronous belt transmission assembly 915.

[0054] In this embodiment, the first synchronous belt drive assembly 78, the second synchronous belt drive assembly 815, and the third synchronous belt drive assembly 915 each consist of two synchronous pulleys and a synchronous belt, with the two pulleys connected by a synchronous belt drive. The tap lateral movement assembly 916 includes a tap lateral movement servo motor, a tap lateral movement ball screw, and at least two tap lateral movement linear guides. The tap lateral movement servo motor and the at least two tap lateral movement linear guides are mounted on the machine base 1. The tap lateral movement ball screw is rotatably mounted on the machine base 1. The output shaft of the tap lateral movement servo motor is connected to the tap lateral movement ball screw. The tap spindle box 912 is slidably mounted on the at least two tap lateral movement linear guides, and the tap lateral movement ball screw is threadedly connected to the bottom of the tap spindle box 912. The tap release drive device 913 is preferably a cylinder, and the tap rotation drive device 914 is preferably a motor.

[0055] By adopting the above technical solution, the tap lateral movement assembly 916 drives the tap 910 to move towards the workpiece via the tapping spindle box 912 and the tapping spindle 911. The tap rotation drive device 914 drives the tapping spindle 911 to rotate via the third synchronous belt drive assembly 915, thereby driving the tap 910 to rotate, realizing the tapping of the workpiece through hole enlargement. When the tap release drive device 913 drives the tapping spindle 911 to release the tap 910, it facilitates the replacement of the tap 910. The structural design of the first tapping mechanism 91 realizes the automation of tapping the workpiece and releasing the tap 910, and has the advantages of high tapping efficiency, good tapping effect, high tapping accuracy and quick tap 910 replacement. In addition, it reduces the defect rate of the workpiece, thereby reducing the production cost of the workpiece.

[0056] The structure and working principle of the second tapping mechanism 92 are the same as those of the first tapping mechanism 91.

[0057] Reference Figure 10 As shown, the top of the machine base 1 is provided with a second chip removal groove 11, and the chip removal assembly 10 is installed in the second chip removal groove 11.

[0058] In this embodiment, the chip removal assembly 10 includes a chip removal servo motor and a helical blade, with the output shaft of the chip removal servo motor connected and installed to the helical blade.

[0059] By adopting the above technical solution, when the chip removal servo motor drives the spiral blades to rotate, it can remove the waste chips in the second chip removal groove 11. It automatically completes the waste chip cleaning without the need for manual cleaning by workers, which reduces the labor intensity of workers and the labor costs of enterprises, so as to achieve low cost, high waste removal efficiency and good waste removal effect.

[0060] Its overall structural design enables automated multi-station workpiece handling and transfer on a single machine, including pre-processing reference positioning, pre-processing limit fixing at each station, drilling, double-sided reaming, double-sided tapping, chip removal and recycling, and pre-unloading reference arrangement. It eliminates the need for separate drilling, reaming, and tapping equipment, reducing enterprise equipment purchase costs and thus workpiece processing costs. It also shortens workpiece handling and transfer time, significantly improving processing efficiency. This achieves high processing efficiency, high precision, and excellent processing results, solving the problems of low workpiece processing efficiency caused by traditional gripper-type robotic arms used for transferring workpieces between different machines, and low workpiece yield rates due to workpiece damage or scratches caused by gripper-type robotic arms. Meanwhile, by sequentially setting the first fixing component 41, the second fixing component 42, and the third fixing component 43 in each processing station to fix the workpiece before processing, each fixing component can fix the workpiece with three-sided reference and limit fixation, so that the workpiece has the advantages of stable limit fixation and good fixation effect, thereby ensuring high processing accuracy, good processing effect and high processing yield of the workpiece. This solves the problem that the workpiece fixing mechanism equipped in the market uses reference block and cylinder side push structure to position the workpiece, which is prone to lateral displacement during processing, resulting in poor workpiece processing accuracy and low yield.

All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
