Description

Technical Field

[0001] The utility model relates to the field of Swiss sewing machines, in particular to a Swiss sewing machine with multiple working stations for processing sewing machine accessories. Background Art

[0002] Swiss-type CNC lathes, also known as Swiss-type CNC lathes, are precision machining equipment that can complete composite machining such as turning, milling, drilling, boring, tapping, and engraving at the same time. They are mainly used for batch processing of precision hardware and special-shaped non-standard shaft parts.

[0003] The utility model patent with announcement number CN111992789A discloses a Swiss lathe power head, including a fixed seat, on which a first mounting portion is provided. The Swiss lathe power head also includes a power device connected to the fixed seat; and a first processing device detachably connected to the first mounting portion. The first processing device includes at least one first tool. The power device is transmission-connected to the first processing device to drive the first tool to rotate.

[0004] The aforementioned Swiss-type lathe power head is typically used in conjunction with a clamping assembly on the machine tool, which is used to clamp and rotate the workpiece. However, when machining a sewing machine component such as a shaft requiring holes on both ends, the Swiss-type lathe must first machine one end of the workpiece, then flip the workpiece over and clamp it with the clamping assembly before machining the other end. This entire process is cumbersome, requiring an operator or a robot to reverse the workpiece, resulting in longer machining times and lower efficiency. Utility Model Content

[0005] In order to improve the processing efficiency of sewing machine accessories, the present application provides a multi-station processing Swiss sewing machine accessories.

[0006] The present application provides a multi-station Swiss-type sewing machine for sewing machine parts, which adopts the following technical solutions:

[0007] A multi-station Swiss-type sewing machine for processing sewing machine parts, comprising a machine tool and a spray assembly, a Swiss-type sewing machine power head, and a clamping assembly provided on the machine tool. The machine tool also comprises a material transfer assembly and a drilling assembly provided on the machine tool. The clamping assembly comprises a pusher, a first chuck, and a first driving member. The first driving member is provided on the machine tool and is used to drive the first chuck to rotate. The pusher is used to push a shaft workpiece on the first chuck out of the chuck.

[0008] The Swiss-type lathe power head is used to process the workpiece clamped on the first chuck and cut off the processed workpiece;

[0009] The material transfer component includes a first driving component, a moving seat, and a second chuck. The first driving component is arranged on the machine tool and is used to drive the moving seat to move. The second chuck is arranged on the moving seat and is used to clamp the semi-finished workpiece to be cut on the first chuck.

[0010] The drilling component includes a fixed seat, a second driving member, a plurality of drill chucks, and a plurality of drill bits. The fixed seat is fixedly arranged on the machine tool. The plurality of drill chucks are rotatably connected to the fixed seat. The second driving member drives the drill chucks to rotate. The drill chucks are used to clamp the drill bits, and the drill bits are used to process the workpiece clamped on the second chuck.

[0011] By adopting the above technical solution, the shaft workpiece is clamped by the first chuck, and then the part to be processed is pushed out by the pusher. The power head of the sliding headstock machine processes it. After this part of the processing is completed, the moving seat moves towards the first chuck, and the second chuck clamps the processed part of the workpiece. Then the power head of the sliding headstock machine cuts off the shaft workpiece, so that the semi-finished products of this part of the sewing machine accessories can be separated separately. Then the second chuck moves it to the drilling component to drill the other end face of the sewing machine accessories. At the same time, the pusher can continue to push out the part to be processed, and the above operations are cycled. During the whole process, the power head of the sliding headstock machine and the drilling component can operate simultaneously, saving processing time and improving the processing efficiency of the sewing machine accessories.

[0012] Preferably, the axes of the first chuck, the second chuck, and the drill chucks are all at the same horizontal height.

[0013] By adopting the above technical solution, the moving path of the moving seat can be simplified as much as possible, and the processing efficiency can be improved.

[0014] Preferably, a material receiving component is arranged on the machine tool. The material receiving component includes a material receiving frame. A material receiving channel is formed in the material receiving frame. The material receiving channel is inclined and the top opening faces the drilling component. A notch for the workpiece to enter is opened at the top opening of the material receiving channel.

[0015] By adopting the above technical solution, after the workpiece on the second chuck is processed, the moving seat continues to move, puts the workpiece into the material receiving channel from the notch, and then the second chuck is loosened to complete the blanking of the workpiece.

[0016] Preferably, the notch is opened in the horizontal direction and is at the same height position as the drill chucks.

[0017] By adopting the above technical solution, after the drilling component processes the workpiece, the moving seat can directly move horizontally to the notch, which can simplify the moving path of the moving seat.

[0018] Preferably, a plurality of water leakage holes are formed in the inner bottom wall of the material receiving channel.

[0019] By adopting the above technical solution, during the drilling process, the spraying assembly continuously sprays coolant for cooling, so the coolant may splash into the material receiving channel. The water leakage holes can drain this part of the coolant into the machine tool, enabling the coolant to be recycled and reducing the waste of coolant.

[0020] Preferably, an observation port is formed in the inner top wall of the material receiving channel, and a transparent plate is detachably connected to the outer surface of the material receiving frame to block the observation port.

[0021] By adopting the above technical solution, the rolling condition of the sewing machine accessories in the material receiving channel can be observed.

[0022] Preferably, the material receiving assembly further includes a material receiving box fixedly arranged outside the machine tool, and the bottom end of the material receiving frame extends out of the machine tool and is located directly above the material receiving box.

[0023] By adopting the above technical solution, the operator can directly take the processed sewing machine accessories from the material receiving box, which is relatively convenient.

[0024] Preferably, the material receiving assembly further includes a partition board, a baffle, a rotating shaft, a connecting rod, a moving plate, a driving member three and a pulling rope. A sliding groove is formed in the top of the bottom end of the material receiving channel. The partition board slides vertically on the sliding groove. Two ends of the connecting rod are respectively fixedly arranged on the partition board and the moving plate. The moving plate is located above the material receiving frame. The driving member three drives the moving plate to slide vertically. When the partition board slides to abut against the bottom wall of the material receiving channel to be in a closed state, the bottom end of the material receiving channel is blocked;

[0025] A waste chip port is formed through the inner bottom wall at the bottom end of the material receiving channel. The waste chip port is located on the side of the partition board away from the material receiving box and is inside the machine tool. The rotating shaft is fixedly arranged at one end of the baffle, and the rotating shaft is rotatably connected to the top end of the waste chip port. Two ends of the pulling rope are respectively arranged on the moving plate and the baffle. When the partition board is in a closed state, the baffle is in an open state; when the partition board is in an open state, the baffle is in a closed state.

[0026] By adopting the above technical solution, since some waste chips will inevitably enter the material receiving channel when the drilling assembly drills holes, in order to conveniently clean the remaining waste chips in the material receiving channel, the driving member three can be used to drive the moving plate to move downward, so that the partition plate is in a closed state. At this time, the baffle is opened, and the operator can directly flush the material receiving channel with a large amount of coolant, and the waste chips will follow the coolant and be discharged from the waste chip outlet, which can conveniently clean the waste chips and reduce the waste chips attached when the sewing machine parts are collected in the material receiving box; during the working state, the driving member three drives the moving plate to move upward, so that the partition plate is in an open state. At this time, the baffle is closed, and the processed sewing machine parts can roll unobstructedly into the material receiving box and be collected.

[0027] The technical effects of the present utility model are mainly reflected in the following aspects:

[0028] 1. During the whole process of the present utility model, the power head of the sliding headstock can operate simultaneously with the drilling assembly, saving processing time and improving the processing efficiency of sewing machine parts;

[0029] 2. By setting the axes of the first chuck, the second chuck and the drill chuck sleeve at the same horizontal height, the moving path of the material moving seat can be simplified as much as possible, and the processing efficiency can be improved. Description of the Drawings
