Description

Technical Field

[0001] This utility model relates to the field of shaft machining technology, and in particular to a straight rod type double-end machining device. Background Technology

[0002] Straight rod shafts come in various forms. Some are cylindrical with grooves and holes machined at one end, while others require machining at both ends, such as fuel injector assemblies. Fuel injector assemblies are precision components requiring extremely high machining accuracy, demanding a wide dynamic flow range, strong anti-clogging and anti-contamination capabilities, and excellent atomization performance. The fuel injector receives injection pulse signals from the ECU to precisely control the fuel injection quantity. Machining straight rod injector assemblies involves machining multiple outer diameters at both ends, typically done in two stages: machining one end first, then removing the workpiece to machine the other end. This often involves manual loading and unloading, resulting in low efficiency and high costs. Therefore, there is an urgent need to develop a device that can machine the different outer diameters at both ends of a straight rod shaft in a single operation. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a straight rod type double-end machining device that can complete the machining of both ends in one go, is easy to use, has high machining efficiency, and low cost.

[0004] To solve this technical problem, the present invention adopts the following solution: a straight rod type double-end machining device, including a frame, a controller, a feeding mechanism mounted on the frame, a first clamping manipulator, a second clamping manipulator, a machining mechanism for machining the workpiece, a first moving mechanism, a second moving mechanism, a third moving mechanism, a first lifting mechanism, a second lifting mechanism, a first fixed seat, a second fixed seat, a first rotary clamping seat, and a second rotary clamping seat. The machining mechanism is mounted on the middle of the frame and can move horizontally and vertically via the first moving mechanism. The first and second rotary clamping seats are respectively mounted on the frame on both sides of the machining mechanism. The machining mechanism has machining units on both sides facing the first and second rotary clamping seats. The feeding mechanism is located on one side of the frame to transport the workpiece to be processed to above the first rotary clamping seat. The first fixed seat... The first rotating clamping seat is mounted on the frame above the first rotating clamping seat and can move laterally via the second moving mechanism. The second fixed seat is mounted on the frame above the second rotating clamping seat and can move laterally via the third moving mechanism. The first clamping robot is mounted on the first fixed seat via the first lifting mechanism, clamps the workpiece to be processed conveyed by the feeding mechanism, and sends it to the first rotating clamping seat to clamp one end of the workpiece to be processed. The second clamping robot is mounted on the second fixed seat via the second lifting mechanism, clamps the workpiece processed at one end on the first rotating clamping seat, and sends it to the second rotating clamping seat to clamp one end of the processed workpiece or clamps the processed workpiece and sends it out. The feeding mechanism, the first clamping robot, the second clamping robot, the machining mechanism, the first moving mechanism, the second moving mechanism, the third moving mechanism, the first lifting mechanism, the second lifting mechanism, the first rotating clamping seat, and the second rotating clamping seat are all connected to and controlled by the controller.

[0005] In a further improvement, the feeding mechanism includes a hopper, a lifting and feeding mechanism, a pushing mechanism, and a conveying mechanism. The lifting and feeding mechanism includes a first drive unit, two spaced and parallel rotating shafts mounted on the frame, two sets of vertical synchronous belts sleeved at both ends of the two rotating shafts, and multiple sets of receiving grooves spaced between the two sets of synchronous belts. The first drive unit is mounted on the frame and its output is connected to and drives one of the rotating shafts to rotate. The hopper is located on one side of the frame, and the hopper's outlet has a limit switch that can be rotatably opened and closed by a second drive unit. The discharge port of the hopper is located on the side of the receiving groove of the lifting and feeding mechanism. The second drive unit drives the limit plate to open and close, so that the workpieces to be processed are sent to the receiving grooves of the lifting and feeding machine at intervals. The conveyor belt of the conveying mechanism is provided with multiple placement grooves for placing the workpieces to be processed at intervals. The pushing mechanism and the conveying mechanism are respectively located on both sides of the lifting and feeding mechanism. The push rod of the pushing mechanism pushes the workpieces to be processed arranged one by one on the receiving grooves to the placement groove at the feeding end of the conveying mechanism. The conveying mechanism transports the workpieces to be processed received by the placement grooves to the top of the first rotating clamping seat.

[0006] In a further improvement, the first and second rotary clamping seats are symmetrically provided with rotary clamping units that can synchronously rotate and clamp two workpieces to be processed. The first and second clamping manipulators are respectively provided with interval clamping mechanisms adapted to the first and second rotary clamping seats. The spacing of each placement groove on the conveyor belt of the conveying mechanism matches the two rotary clamping units of the first rotary clamping seat. The turning mechanism is provided with two sets of turning units that are matched in position on both sides facing the first and second rotary clamping seats.

[0007] Further improvements include a second conveying mechanism, the feeding end of which is located above the second rotary clamping seat to receive the processed workpiece held by the second clamping robot, and a collection frame is provided below the discharge end of the second conveying mechanism.

[0008] In a further improvement, a discharge groove is provided above the second rotary clamping seat, and the feed end of the discharge groove is located below the second clamping robot to receive the processed workpiece held by the second clamping robot.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By setting a first rotary clamping seat and a second rotary clamping seat on both sides of the machining mechanism to respectively clamp one end of the workpiece to be processed, the workpiece to be processed, conveyed by the first clamping robot, is fed to the first rotary clamping seat to clamp one end of the workpiece. Then, the machining mechanism performs machining on the free end of the workpiece to be processed with different outer diameters. The second clamping robot clamps the workpiece with one end processed and sends it to the second rotary clamping seat, which clamps the processed end. Then, the machining mechanism performs machining on the other end of the workpiece with multiple different outer diameters. After processing, the second clamping robot clamps the workpiece with both ends processed and sends it to the next process. This allows for the one-time completion of machining operations such as machining multiple different outer diameters at both ends of a straight rod injector assembly. This device allows for double-end processing of workpieces, eliminating the need for multiple processing steps or batch processing, and avoiding repeated handling and unloading of workpieces. It is convenient to use, highly efficient, and cost-effective. The feeding mechanism, composed of a hopper, lifting and feeding mechanism, pushing mechanism, and conveying mechanism, ensures convenient and precise transport of the workpieces, improving efficiency. The first and second rotary clamping seats are symmetrically equipped with rotary clamping units capable of simultaneously clamping two workpieces. The machining mechanism, first clamping robot, and second clamping robot are adapted to each other, enabling the device to process two workpieces at once, further improving processing efficiency. The overall layout is reasonable and space-saving. A second conveying mechanism or unloading chute allows the processed workpieces to be automatically sent to a collection box for storage or to the next processing step, making it widely applicable.
