Description

Technical Field

[0001] The invention relates to a processing device, in particular to a mirror frame processing device using the mirror frame processing device. Background Art

[0002] In the prior art, the processing of each contour line of the plate frame requires multiple processes. If multiple processes are completed by tool change, it is inevitable that the tool change time is wasted. If the processing position is changed, the plate needs to be re-clamped, which will also affect the processing efficiency, especially when processing the outer frame curve of the frame, because the fixture is more complicated, changing the processing position will waste a lot of time. At the same time, tool change means that a corresponding tool holder needs to be set up, which increases the cost of the entire equipment.

[0003] On the other hand, the processing of the frame requires two steps: inner hole processing and outer frame processing. Each processing step requires at least four-axis movement. At the same time, in order to ensure the movement of the workpiece between the two processing steps, an additional translation mechanism is also required, resulting in a large number of drive devices for the entire equipment, which ultimately increases the cost of the production equipment. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a frame processing device which combines and simplifies the movement of the plate and the action of the cutter head as much as possible while ensuring the processing effect.

[0005] In order to achieve the above-mentioned purpose, the frame processing equipment designed by the present invention includes a frame plate, at least two corresponding workstations, and two sets of processing spindles corresponding to the two workstations, wherein:

[0006] A No. 1 Z-axis lifting platform is fixedly arranged on one side of the upper part of the frame plate, a No. 1 Y-axis translation platform is arranged on the No. 1 Z-axis lifting platform through a slide rail, a No. 1 tool holder cantilever is arranged on the No. 1 Y-axis translation platform through a slide rail, and a movable end of the No. 1 tool holder cantilever extends to the front side of the frame plate and is connected to a No. 1 machining spindle;

[0007] An X-axis translation slide is arranged on the lower bottom surface of the frame plate, a main connecting cantilever is connected to the X-axis translation slide via a slider, and an X-axis translation slide drive device is connected to the main connecting cantilever, one end of the main connecting cantilever extends to the front side of the frame plate and is provided with a No. 1 main tooling fixture, and the position of the No. 1 main tooling fixture corresponds to the position of the No. 1 processing spindle, the No. 1 main tooling fixture comprises a No. 1 Z-axis rotating table, a No. 1 fixture lifting platform and a clamp, the No. 1 Z-axis rotating table is directly arranged on the main connecting cantilever, the No. 1 fixture lifting platform is arranged on the No. 1 Z-axis rotating table, and the clamp is symmetrically arranged on both sides of the No. 1 fixture lifting platform;

[0008] A No. 2 X-axis translation platform is arranged on the other side of the upper part of the frame plate, a No. 2 Z-axis lifting platform is arranged on the No. 2 X-axis translation platform through a slide rail, a No. 2 Y-axis translation platform is arranged on the No. 2 Z-axis lifting platform through a slide rail, a No. 2 tool holder cantilever is arranged on the No. 2 Y-axis translation platform through a slide rail, and a movable end of the No. 2 tool holder cantilever extends to the front side of the frame plate and is connected to a No. 2 machining spindle;

[0009] A rotating shaft is arranged at the upper part of the frame plate near the No. 2 X-axis translation platform through a bearing seat and a bearing, one end of the rotating shaft extends to the front side of the frame plate and is arranged with a No. 2 tooling fixture, and the position of the No. 2 tooling fixture corresponds to the position of the No. 2 machining spindle, the No. 2 tooling fixture comprises a No. 2 Y-axis flip table, a No. 2 Z-axis rotating table and a tensioning column, the No. 2 Y-axis flip table rotates synchronously with the rotating shaft, the No. 2 Z-axis rotating table is arranged on the No. 2 Y-axis flip table, the tensioning columns are arranged in groups of two, and at least two groups are symmetrically arranged on the No. 2 Z-axis rotating table;

[0010] A loading rack is also provided on the front side of the frame plate, and the loading rack is further away from the frame plate than the No. 1 main tooling fixture.

[0011] The characteristic of this technical solution is that two processing stations are set up on one device, corresponding to the outer frame and inner hole of the mirror frame. The No. 1 main fixture not only plays the role of a fixture when processing the inner hole, but also takes on the work of clamping the plate from the unloading device and conveying the plate to the No. 2 fixture. Furthermore, it cooperates with the No. 1 processing spindle to undertake the X-axis translation action during the processing.

[0012] In order to complete the processing of the inner hole of the mirror frame in one go, a No. 1 tool head plate is arranged at the front end of the No. 1 tool holder cantilever, and a No. 1 tool head plate is arranged with a plurality of slide rails in a horizontal array on the front side, and a tool head seat is arranged on each slide rail through a sliding pair, and a No. 1 electric spindle tool head is arranged on each tool head seat, and tool head lifting cylinders corresponding to the number of tool head seats are arranged on the bottom surface of the No. 1 tool head plate, and the movable end of the tool head lifting cylinder is connected to the tool head seat, and each No. 1 electric spindle tool head is arranged with different tools.

Each No. 2 electric spindle tool head is provided with different tools, and a rotary drive mechanism is fixedly provided on the No. 2 tool holder cantilever.

[0016] By rotating multiple tool heads, the time for disassembling and assembling tool heads from the tool holder for automatic tool change is saved, the tool change efficiency is improved, and the cost of the tool holder is saved.

[0017] Considering the complexity of the curved surface processing of the mirror frame, six cutter seats are arranged on the second wheel rotating disk, and the wheel rotation drive mechanism is a servo motor. The wheel rotation drive mechanism, the second wheel rotating spindle and the second wheel rotating disk form a planetary gear train, wherein the wheel rotation drive mechanism corresponds to the asteroid wheel, the second wheel rotating spindle corresponds to the sun wheel, and the second wheel rotating disk corresponds to the gear ring.

[0019] By setting the No. 1 fixture translation platform, the No. 1 main fixture can perform translation insertion when clamping the plate from the loading rack, making the clamping smoother. At the same time, it can also cooperate with the No. 1 auxiliary fixture to control the plate to be inserted into the clamping claw of the No. 1 auxiliary fixture, ensuring the fixing effect.

[0020] The frame processing equipment designed by the present invention uses the No. 1 main tooling fixture used for inner hole processing as the main conveying equipment, and connects the loading rack, No. 1 processing position and No. 2 processing position in series through reasonable design of processing equipment and processing method. At the same time, by utilizing its characteristic of being able to translate on the X-axis, it directly cooperates with the No. 1 processing spindle to undertake the displacement work in the X-axis direction during the processing, which not only improves the work efficiency, but also saves a set of No. 1 processing spindle X translation equipment and drive device. On the other hand, by setting multiple electric spindle tool heads of different types, it is fully adapted to the processing of the inner hole and outer frame of the frame. At the same time, according to different processing conditions, different electric spindle tool head rotation methods are set, which effectively improves the switching efficiency and saves the production cost of the equipment. In summary, this frame processing equipment has the characteristics of reasonable design, accurate precision, high efficiency and full automation. BRIEF DESCRIPTION OF THE DRAWINGS
