Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machine tools, in particular to a machining jig for numerical control machine tools. BACKGROUND

[0002] A numerical control machine tool, in full a numerical control machine tool, is a highly automated mechanical device equipped with a program control system. This system can process programs logically and decode them into coded digital information according to input control codes or other symbolic instructions. These digital information is input into the numerical control device through various information carriers such as magnetic tape or network. Numerical control machining technology has been widely used in various fields. At present, most of the mechanical processing workshops have the ability to use numerical control machine tools for processing.

[0003] A numerical control machine tool mainly consists of two core parts, namely a positioning jig and a milling and engraving device. In the production process of mechanical processing, the positioning jig is first used to accurately clamp and position the workpiece. Then, the positioning jig is driven to rotate accurately to ensure that the workpiece maintains the correct posture during processing. Next, the milling and engraving device starts to finely process the workpiece by accurately controlling the motion trajectory of the workpiece to achieve the required size and shape on the design drawing.

[0004] In view of the related technology in the above, in the current workpiece processing process, in most cases, the workpiece can only rotate along a single rotation axis. This limitation makes the motion trajectory of the workpiece relatively single and limited, and therefore needs to be improved. CONTENT OF THE INVENTION

[0005] In order to improve the complexity of the motion trajectory of the workpiece, the present application provides a machining jig for numerical control machine tools.

[0006] The machining jig for numerical control machine tools provided by the present application adopts the following technical scheme:

[0007] A machining jig for numerical control machine tools, comprising a base, a first rotating disc, a second rotating disc, a first motor, a connecting seat, a positioning disc and a second motor, the first rotating disc and the second rotating disc are oppositely arranged and are both rotatably connected to the base, the rotation axes of the first rotating disc and the second rotating disc are the same, the first motor is connected to the first rotating disc and is used to control the rotation of the first rotating disc; the connecting seat is arranged on the first rotating disc and the second rotating disc, the positioning disc is rotatably connected to the connecting seat, the rotation axis of the positioning disc is different from the rotation axis of the first rotating disc, the second motor is arranged on the connecting seat and is connected to the positioning disc, and the second motor is used to control the rotation of the positioning disc.

[0008] By adopting the technical scheme, the workpiece can be placed on the positioning disc and clamped by the quick clamp during processing. The second motor can control the positioning disc to rotate by 360 degrees, and the first motor can control the entire connecting seat to rotate, thereby indirectly driving the positioning disc to rotate. Since the rotation shafts of the positioning disc and the connecting seat are not the same, the movement track of the workpiece can be more complex, thereby producing more delicate products.

[0009] Preferably, the connecting seat is detachably connected to the first rotary disc and the second rotary disc.

[0010] By adopting the technical scheme, when the second motor and the positioning disc are damaged, the entire connecting seat can be disassembled for maintenance.

[0011] Preferably, the first rotary disc is provided with a first clamping groove, the second rotary disc is provided with a second clamping groove, and the two ends of the connecting seat are clamped in the first clamping groove and the second clamping groove and locked by a fastener.

[0012] By adopting the technical scheme, the two ends of the connecting seat are clamped in the first clamping groove and the second clamping groove, and the connecting seat is preliminarily fixed by clamping force, and then locked by the fastener.

[0013] Preferably, the fastener is a fastening bolt or a fastening screw.

[0014] By adopting the technical scheme, the fastening bolt or the fastening screw is a detachable object.

[0015] Preferably, the connecting seat is provided with a material-saving cavity, the material-saving cavity is provided with a transparent plate, and the second motor is below the transparent plate.

[0016] By adopting the technical scheme, the material-saving cavity can reduce the material consumption of the connecting seat and reduce the cost, and can also reduce the weight of the entire connecting seat, facilitating the rotation of the connecting seat driven by the first rotary disc and the second rotary disc. The existence of the transparent plate can block the debris generated during processing, avoiding the debris falling directly onto the second motor.

[0017] Preferably, the positioning disc is provided with a positioning groove for positioning the workpiece.

[0018] By adopting the technical scheme, the positioning groove can position the workpiece, improving the stability of the workpiece during processing.

[0019] Preferably, the positioning disc is provided with a positioning groove for positioning the workpiece.

[0020] By adopting the above technical solution, when a workpiece needs to be processed, the operator first controls the positioning plate to rotate, causing the positioning piece to fall into the groove. At this time, the positioning sensor will detect the presence of the positioning piece and then transmit the signal to the first motor and the second motor to start working. Through the cooperation of the positioning sensor and the positioning piece, the initial position of the positioning plate can be easily established.

[0021] Preferably, an arc-shaped piece is integrally connected to the positioning piece, and the arc-shaped piece is bolted to the positioning disk.

[0022] By adopting the above technical solution, the arc-shaped piece can fit well on the positioning plate, and the bolt locking method can make the positioning piece and the positioning plate detachable.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting up a first rotating disk, a second rotating disk, a first motor, a connecting seat, a positioning disk, and a second motor, during processing, the workpiece can be placed on the positioning disk and clamped using a quick clamp. The second motor can control the positioning disk to rotate 360 ​​degrees, while the first motor can control the entire connecting seat to rotate, thereby indirectly driving the positioning disk to rotate. Since the rotating shafts of the positioning disk and the connecting seat are not the same, this can make the movement trajectory of the workpiece more complex.

[0025] (2) By setting a positioning groove on the positioning plate, the positioning groove can position the workpiece and improve the stability of the workpiece during the processing.

[0026] (3) By setting up positioning sensors and positioning plates, the initial position of the positioning disk can be established by the cooperation of the positioning sensors and positioning plates. Attached Figure Description

[0035] Some embodiments of the present application will be described in detail below in conjunction with the drawings. Those skilled in the art can combine and combine the different embodiments or examples represented in the present application and the features of the different embodiments or examples without conflict.

[0036] The embodiments of the present application disclose a machining jig for a numerical control machine tool. Referring to Figure 1 and Figure 2The machining tool includes a base 1, a first rotating disc 2, a second rotating disc 3, a first motor 4, a connecting seat 5, a positioning disc 6 and a second motor 7. The base 1 is fixedly installed on an external workbench as a support carrier. The first rotating disc 2 and the second rotating disc 3 are horizontally arranged opposite to each other and are rotatably connected to the base 1. The rotating shafts of the first rotating disc 2 and the second rotating disc 3 are the same and are in a horizontal direction. The first motor 4 is installed on the base 1. An output shaft of the first motor 4 is connected to the first rotating disc 2 and is used to control the first rotating disc 2 to rotate. The first motor 4 has a self-locking function. The connecting seat 5 is used to connect the first rotating disc 2 and the second rotating disc 3. The positioning disc 6 is rotatably connected to the connecting seat 5. The rotating shaft of the positioning disc 6 is different from the rotating shaft of the first rotating disc 2. In this embodiment, the rotating shaft of the positioning disc 6 is in a vertical direction and is perpendicular to the rotating shaft of the first rotating disc 2. The second motor 7 is installed on the connecting seat 5 and is connected to the positioning disc 6. The second motor 7 is used to control the positioning disc 6 to rotate. The second motor 7 has a self-locking function. A positioning groove 8 is formed in the positioning disc 6 and is used to position a workpiece.

[0037] During machining, the workpiece can be placed in the positioning groove 8 of the positioning disc 6 and is clamped by a quick clamp. The second motor 7 can control the positioning disc 6 to rotate by 360 degrees. Meanwhile, the first motor 4 can control the connecting seat 5 to rotate, thereby indirectly driving the positioning disc 6 to rotate. Since the rotating shafts of the positioning disc 6 and the connecting seat 5 are different, the movement track of the workpiece is more complex, thereby producing more delicate products.

[0038] Specifically, the connecting seat 5 is detachably connected to the first rotating disc 2 and the second rotating disc 3. A first clamping groove 9 is formed in the first rotating disc 2. A second clamping groove 10 is formed in the second rotating disc 3. The two ends of the connecting seat 5 are clamped in the first clamping groove 9 and the second clamping groove 10 and are locked by a fastener 11, which is a detachable object such as a fastening bolt or a fastening screw.

[0039] In this embodiment, the connecting seat 5 is in a rectangular shape. A material-saving cavity 12 is formed in the connecting seat 5 and is also in a rectangular shape. The material-saving cavity 12 can reduce the material consumption of the connecting seat 5, thereby reducing the cost. On the other hand, the material-saving cavity 12 can reduce the weight of the connecting seat 5, thereby facilitating the first rotating disc 2 and the second rotating disc 3 to drive the connecting seat 5 to rotate. A transparent plate (not shown in the figure) is sealingly arranged on the material-saving cavity 12. The transparent plate can be a PMMA plate or a glass plate. The second motor 7 is below the transparent plate. The transparent plate is used to intercept machining debris from falling onto the second motor 7.

[0040] In combination with Figure 3In addition, the connecting seat 5 is further provided with a positioning sensor 13, the positioning sensor 13 is close to the first rotary disc 2, and a groove 14 is formed on the side of the positioning sensor 13, facing the positioning disc 6. The outer circumferential side of the positioning disc 6 is detachably connected with a positioning sheet 15, and the positioning sensor 13 is used for sensing the positioning sheet 15. When the workpiece needs to be machined, the staff first controls the positioning disc 6 to rotate, so that the positioning sheet 15 falls into the groove 14, at this time, the positioning sensor 13 will sense the existence of the positioning sheet 15, and then transmit a signal to the first motor 4 and the second motor 7 to start working. Through the cooperation of the positioning sensor 13 and the positioning sheet 15, the initial position of the positioning disc 6 can be conveniently established. The arc-shaped sheet 16 is integrally connected to the positioning sheet 15, the arc-shaped sheet 16 is attached to the positioning disc 6, and is locked by bolts. The arc-shaped sheet 16 can increase the contact area of the positioning sheet 15 and the positioning disc 6, and the bolts are threadedly connected to the positioning disc 6 through the arc-shaped sheet 16, so that the positioning sheet 15 can be detachable.

[0041] The implementation principle of the machining jig for numerical control machine tool provided by the embodiment of the application is as follows: in the machining process, the workpiece can be placed in the positioning groove 8 of the positioning disc 6 and fixed by the quick clamp. The second motor 7 is responsible for driving the positioning disc 6 to rotate by 360 degrees, and the first motor 4 controls the connecting seat 5 to rotate, thereby indirectly driving the positioning disc 6 to rotate. Due to the difference between the rotation shafts of the positioning disc 6 and the connecting seat 5, the movement track of the workpiece is more complex, and thus more delicate products can be manufactured.

[0042] The above are preferred embodiments of the application, and do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape and principle of the application should be covered within the protection scope of the application.
