Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a positioning fixture in a multi-angle processing device. Background Art

[0002] With the continuous development of mobile terminal technology, the application of electronic devices such as smart phones, PDAs, and smart watches has become extremely common and has become an important part of people's work and life. The shell of electronic devices usually adopts a metal back shell structure. The metal back cover has extremely complex requirements for the product and can make the product leave a high-end impression on the user.

[0003] Existing products are usually formed through simple three-axis or four-axis processing, but for more complex curvatures, existing equipment and processes cannot meet the requirements of complex curvatures, resulting in poor applicability. Summary of the invention

[0004] The purpose of the utility model is to provide a positioning fixture in a multi-angle processing device with high applicability and compact structure in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A positioning fixture in a multi-angle processing device includes a frame, the upper part of the frame is provided with a tool for cutting processing, and is characterized in that it also includes a slide plate 1, a slide plate 2, a turntable and a material seat, the lower part of the frame is provided with a guide rail, the slide plate 1 is connected to the guide rail and the slide plate 1 can translate forward and backward along the guide rail, the slide plate 2 is connected to the slide plate 1 and a guide structure is provided therebetween, under the action of the guide structure, the slide plate 2 can translate left and right relative to the slide plate 1, the turntable is axially fixed at the slide plate 2 and the turntable can rotate relative to the slide plate 2, the material seat is connected to the turntable and the upper part of the material seat can position the parts to be processed, and the material seat can rotate relative to the turntable.

[0007] The workpiece to be processed is placed on the material seat. Under the action of external force, the slide moves along the guide rail, and the material seat can move forward and backward.

[0008] External force is applied to the slide rail 2 alone, and the lower slide rail 2 moves along the slide rail 1 under the action of the external force and the guide structure, and the material seat can move left and right during the movement.

[0009] The guide structure is another guide rail arranged along the length direction of the first slide plate, and the second slide plate is connected to the guide rail.

[0010] After the turntable and the material seat rotate, each position of the workpiece to be processed can be placed at a set processing position. After the tool on the processing device is fed, corresponding cutting processing can be performed at each position of the workpiece to be processed.

[0011] In the positioning fixture in the above-mentioned multi-angle processing device, the turntable includes a fixed seat one, a fixed seat two and a table body with connecting shafts at both ends thereof, the fixed seat one and the fixed seat two are respectively fixedly connected at the two ends of the slide plate two, the connecting shaft at one end of the above-mentioned table body is axially fixed at a fixed seat one and the connecting shaft can rotate relative to the fixed seat one, and the connecting shaft at the other end of the above-mentioned table body is axially fixed at a fixed seat two and the connecting shaft can rotate relative to the fixed seat two.

[0012] The connecting shafts at both ends of the platform are axially fixed at the corresponding fixing seat 1 or fixing seat 2 respectively. Therefore, under the action of this structure, the platform can rotate smoothly between the fixing seat 1 and the fixing seat 2.

[0013] In the positioning fixture in the above-mentioned multi-angle processing device, the connecting axes at both ends of the table body are arranged coaxially.

[0014] Such a structure can appropriately improve the compactness of the platform structure, and during assembly, it is not necessary to distinguish the installation position of the platform in the left and right directions.

[0015] In the positioning fixture in the above-mentioned multi-angle processing device, the interior of the fixing seat 2 is a cavity and a driving member 1 is connected inside the fixing seat 2, and the driving member 1 is fixedly connected to one of the connecting shafts.

[0016] The first driving member is a motor, and the rotating shaft of the motor is fixedly connected to one of the connecting shafts. After the motor is activated, it can drive the platform to rotate together.

[0017] In the positioning fixture in the above-mentioned multi-angle processing device, the first driving component is a servo motor.

[0018] The servo motor can accurately control the swing or rotation amplitude of the console.

[0019] In the positioning fixture in the above-mentioned multi-angle processing device, the material seat includes a bracket, a second driving member and a pressure rod. The above-mentioned bracket is fixedly connected to the upper part of the table body, the above-mentioned second driving member is fixedly connected to the lower part of the bracket, the above-mentioned pressure rod is located at the upper part of the bracket and the pressure rod is connected to the second driving member, and the above-mentioned second driving member can drive the pressure rod to move up and down.

[0020] After the driving member drives the pressure rod to move downward, the workpiece to be processed can be stably pressed between the pressure rod and the bracket, which can prevent the workpiece from being displaced or loosened during the subsequent processing.

[0021] In the positioning fixture in the above-mentioned multi-angle processing device, the bracket is in an inverted U shape, the two ends of the U-shaped opening of the bracket are fixedly connected to the table body, and the above-mentioned driving member 2 is located at the U-shaped notch of the bracket.

[0022] In the positioning fixture in the above-mentioned multi-angle processing device, a base for supporting the workpiece to be processed is fixedly connected to the upper part of the bracket, and after the driving member 2 drives the pressure rod to move downward, the workpiece to be processed can be tightly pressed between the pressure rod and the base.

[0023] The inverted U-shaped bracket reduces the bracket material consumption, and the bracket covers the second driving member, effectively preventing the second driving member from being affected by the outside world, and appropriately improving its stability.

[0024] In the positioning fixture in the multi-angle processing device, the left-right moving direction of the slide plate 2 is X, and the platform body rotates around the X direction.

[0025] In the positioning fixture in the multi-angle processing device, a driving member three is fixedly connected to the table body, and the driving member three is fixedly connected to the bracket, and the driving member three can drive the bracket to rotate.

[0026] In the positioning fixture in the above-mentioned multi-angle processing device, the up and down moving direction of the above-mentioned pressure rod is Z, and the driving member 3 can drive the material seat to rotate around the Z direction.

[0027] The rotation direction of the table body is different from that of the material seat, and after coordinated action, each position of the workpiece to be processed can enter the corresponding processing operation position.

[0028] Compared with the prior art, the positioning fixture in the multi-angle processing device can rotate the positioned workpiece forward and backward, left and right, and in two different directions. Therefore, most positions of the positioned workpiece can enter the cutting processing operation, thereby enabling cutting processing on workpieces with complex structures, and its applicability is relatively high.

[0029] At the same time, since the slide plate 1, the slide plate 2, the turntable and the material seat are centrally arranged in the device, the structure is relatively compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
