Description

Technical Field

[0001] The utility model belongs to the field of CNC machining fixtures, and specifically relates to a cutting waste blowing device. Background Art

[0002] CN cutting is a method of precise cutting machining by controlling a machine tool through a computer numerical control (CNC) system. This machining method is widely used in the manufacturing industry, including fields such as automotive, aerospace, medical equipment, and electronic equipment.

[0003] The process of CNC cutting has high precision and can achieve precise machining of complex parts. It has a high degree of automation, can meet the needs of continuous machining of large quantities of parts, and is controlled by a numerical control program, which can quickly adjust the machining process to adapt to the machining needs of different parts. At the same time, it can also greatly reduce the errors of manual operation and provide the consistency and stability of workpiece machining.

[0004] When performing CNC machining on a laptop computer case, it is usually necessary to use a fixture that matches the specific laptop computer case. During machining, waste chips will inevitably be generated. However, it is difficult to handle the waste that falls into the grooves of the fixture, and excessive accumulation of waste will cause problems such as uneven installation of the workpiece. Therefore, during the continuous machining production process, it is necessary for the operator to regularly observe whether the waste affects the installation of the workpiece and perform manual cleaning, which seriously slows down the overall machining progress.

[0005] Therefore, a new design that can automatically and timely clean the cutting waste of the fixture during the normal cutting process is needed. Summary of the Utility Model

[0006] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a cutting waste blowing device.

[0007] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0008] A cutting waste blowing device includes a base and an upper pressing plate. The base is provided with an installation groove, and the installation groove is a groove structure with a raised edge and a sunken middle. The bottom of the installation groove is provided with air blowing holes penetrating the side wall of the installation groove. A backing plate is arranged above the installation groove, and the upper pressing plate is arranged above the backing plate. The middle part of the upper pressing plate is provided with a pressing groove that matches the position of the backing plate.

[0009] A waste tray is arranged on the periphery of the base.

[0010] A positioning groove is arranged on the base, and the upper pressing plate is provided with a positioning block that matches the positioning groove of the base.

[0011] A plurality of the air blowing holes are provided and arranged around the mounting groove.

[0012] An air pipe groove is provided at the position of the base corresponding to each air blowing hole.

[0013] The extrusion groove and the backing plate are stamping dies that match each other.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] Through the special design of the fixed table surface of the workpiece, the present utility model opens the side wall of the mounting groove for placing the workpiece to be processed, sets air blowing holes, and reserves an air pipe groove for facilitating the connection of the air inlet pipe at the part of the air blowing hole on the outer side of the base. After the milling of the workpiece is completed, the inside of the mounting groove and the surface of the backing plate are directly purged through the air blowing holes. And with the blowing in multiple directions, the inside of the backing plate and the mounting groove can be purged more thoroughly. At the same time, a waste material support plate is also arranged on the periphery of the base, which can block and collect the cutting waste purged out in the waste material support plate for centralized cleaning, effectively preventing the waste chips from flying around and affecting the working environment of the milling equipment.

[0021] The present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 and Figure 2 shown, the present utility model mainly includes two parts, namely a base 1 and an upper pressing plate 7. Among them, the base 1 is mainly used to carry the workpiece to be processed and serve as a fixing jig to fix the workpiece. After the workpiece is placed on the base plate 1, the upper pressing plate 7 is mainly used to perform preliminary extrusion and leveling on the surface of the workpiece that needs to be milled to ensure the accuracy of milling.

[0023] As Figure 3As shown in the figure, an installation groove 2 is provided above the base 1. The overall structure of the installation groove 2 is a box-shaped groove structure with the middle part sunken downward. Above the installation groove 2, a backing plate 10 is provided. The backing plate 10 is a flat structure as a whole. Grooves are provided in the part of the workpiece that needs to be milled to receive the milled waste and prevent the milling cutter head from directly contacting the backing plate 10 for milling. At the same time, a plurality of through holes communicating with the installation groove 2 are also provided on the backing plate 10.

[0024] A plurality of air blowing holes 3 are opened on the outer side wall of the installation groove 2. And on the base 1, a tracheal groove 4 is provided corresponding to each air blowing hole 3. The air source pipeline is connected to the air blowing hole 3 through the tracheal groove 4 to realize the function of blowing air into the installation groove 2. And in cooperation with the through holes on the backing plate 10, it is possible to blow air from the bottom installation groove 2 in the reverse direction towards the backing plate 10. The air flow blows out from the through holes and is then blocked by the upper pressing plate 7 located above the base 1. Then the air flow blows downward, taking away the milling debris remaining on the backing plate 10.

[0025] If the milling debris falls into the installation groove 2 through the through holes on the backing plate 10, due to the sunken design of the installation groove 2, it can accommodate more milling debris, and the through holes of the backing plate 10 are small, so it is also difficult for a large amount of debris to fall in. The user may wait until all the workpieces in a batch are processed, then remove the backing plate 10. At this time, the installation groove 2 is directly exposed, and then air is blown through the air source pipeline. At this time, the moving mode of the air flow driving the debris is the same as that of blowing the debris on the backing plate 10. After being blocked by the upper pressing plate 7, the debris is blown from the installation groove 2 to the outside of the base 1.

[0026] In order to prevent the debris from flying around after being blown, waste material support plates 9 are respectively provided around the base 1 to receive the blown debris and prevent the debris from flying around and polluting the working environment of the milling machine.

[0027] In this embodiment, an extrusion groove 8 is also opened at the bottom of the upper pressing plate 7 corresponding to the backing plate 10 on the installation groove 2. The structure of the extrusion groove 8 matches the structure of the backing plate 10. After the upper pressing plate 7 is pressed down to the limit position, the remaining gap between the extrusion groove 8 and the backing plate 10 is the shape and size of the workpiece to be processed, which can effectively flatten the workpiece to be processed.

[0028] In addition, the outer part of the extrusion groove 8 can be modified so that the extrusion groove 8 and the backing plate 10 form a pair of stamping die tools, and this structure can directly complete the steps of stamping and hole milling of the sheet material through one device.

[0029] To ensure the accurate movement of the upper pressure plate 7 during the downward pressing process, a number of positioning grooves 5 are also provided on the base 1, and positioning blocks 6 corresponding to the positioning grooves 5 are provided at symmetrical positions at the bottom of the upper pressure plate 7. Through the positioning of the positioning blocks 6, it is ensured that the extrusion groove 8 at the bottom of the upper pressure plate 7 can be corresponding to the die closing of the backing plate 10 after being completely pressed down, completing the work of workpiece leveling or stamping forming.
