Description

Technical Field

[0001] The present application relates to the field of reflective film production equipment, and in particular to a high-precision deflection processing device for a micro-prism structure. Background Art

[0002] Micro-prism reflective structures are primarily used in reflective markings on the rear of trucks and on highways. By covering the reflective markings with micro-prism reflective film, they provide a reflective warning. Micro-prism reflective film requires a micro-prism mold. The micro-prism structure on existing micro-prism molds requires a customized tool. By mounting the tool on a drive mechanism, the tool presses against the sheet, creating a fixed groove pattern in the sheet to achieve the reflective effect.

[0003] The relevant micro-prism structure processing device includes a tool and a driving mechanism. The driving mechanism is used to drive the tool to move in multiple directions. The tool is provided with a cutting surface 1 and a cutting surface 2. The cutting surface 1 and the cutting surface 2 form an angle. In order to process the predetermined micro-prism structure on the copper plate, the user needs to customize the tool so that the angle between the cutting surface 1 and the cutting surface 2 on the tool conforms to the predetermined micro-prism structure shape.

[0004] The above-mentioned related technical solutions have the following defects: the cost of customized tools is high, and the precision of customized tools decreases after wear during use, so the service life of customized tools is short, resulting in high production costs. Utility Model Content

[0005] In order to reduce the production cost of reflective film, the present application provides a high-precision deflection processing device for a micro-prism structure.

[0006] The present application provides a high-precision deflection processing device for micro-prism structures, which adopts the following technical solutions:

[0007] A high-precision deflection processing device for micro-prism structure includes a rotating shaft, a tool, a piezoelectric motor and a mounting bracket. The tool is detachably connected to the rotating shaft, the rotating shaft is perpendicular to the length direction of the tool, the rotating shaft is rotatably connected to the mounting bracket, and the piezoelectric motor is used to drive the rotating shaft to rotate. The tool is provided with cutting surface one and cutting surface two, the cutting surface one and cutting surface two are set at an angle, and the intersection line of cutting surface one and cutting surface two is parallel to the rotating shaft.

[0008] By adopting the above technical solution, a tool is set on the rotating shaft so that the position of the tool can be adjusted by the rotating shaft. When the tool falls and presses a groove on the copper plate, the shape of the groove is the same as the angle between the cutting surface one and the cutting surface two on the tool. The user controls the tool to move upward and rotates the rotating shaft, thereby offsetting the tool. After the tool moves, it falls into the groove of the copper plate again, so that the groove of the copper plate can be processed into different shapes. The user can use a lower-cost tool for processing. After the tool is worn, the user polishes the tool. The polished tool can continue to be used to press grooves on the copper plate, thereby reducing production costs.

[0009] Optionally, a tool holder is fixed on the rotating shaft, and a tool is inserted into and detachably connected to the tool holder.

[0010] By adopting the above technical solution, a tool holder is set on the rotating shaft, so that the tool can be inserted into the tool holder, and then the rotating shaft is connected to the tool. The user can set bolts on the tool holder to increase the connection strength between the tool and the rotating shaft.

[0011] Optionally, the mounting frame is connected to a driving mechanism, the driving mechanism is connected to a workbench, the workbench is horizontally arranged, the workbench is used to place workpieces to be processed, and the driving mechanism is used to drive the mounting frame to move relative to the workbench.

[0012] By adopting the above technical solution, a driving mechanism is set on the workbench and the mounting frame is connected to the driving mechanism. The user can lay the copper plate flat on the workbench, move the tool through the driving mechanism, and rotate the rotating shaft through the piezoelectric motor. The position of the tool can be adjusted, so that the tool can press down the same position on the copper plate multiple times and process micro-ridge structures of different shapes.

[0013] Optionally, the driving mechanism includes a hydraulic cylinder, a lifting plate, power rail 1, a sliding plate and power rail 2, one end of the hydraulic cylinder is fixed on the workbench, and the other end is connected to the lifting plate, power rail 1 is connected between the lifting plate and the sliding plate, power rail 2 is installed between the sliding plate and the mounting frame, and power rail 1 and power rail 2 are used to drive the mounting frame to move relative to the workbench.

[0014] By adopting the above technical solution, a lifting plate is set on the hydraulic cylinder, and the user controls the extension and retraction of the hydraulic cylinder so that the lifting plate can drive the mounting frame to move vertically back and forth on the workbench, so that the tool can be pressed down on the copper plate. By setting a sliding plate on the lifting plate, the sliding plate can slide relative to the lifting plate, and then the mounting frame can move along the length direction of power rail one and power rail two respectively, thereby improving the flexibility of tool movement.

[0015] Optionally, the driving mechanism is provided with multiple slide rails, each slide rail is slidably connected to a supporting slider, the slide rails are installed on a lifting plate or a sliding plate, the supporting slider is installed on a sliding plate or a mounting frame, the slide rails on the lifting plate are connected to the supporting slider on the sliding plate, and the slide rails on the sliding plate are connected to the supporting slider on the mounting frame.

[0016] By adopting the above technical solution, by arranging a slide rail on the driving mechanism and arranging a supporting slider in the slide rail, the slide rail and the supporting slider play a supporting role. When the tool falls and abuts against the copper plate, the driving mechanism is subjected to stress, and the slide rail and the supporting slider can distribute the stress, reducing the degree of stress concentration on power rail one and power rail two, thereby achieving the effect of protecting power rail one and power rail two.

[0017] Optionally, a plurality of clamps are provided on the workbench, and the clamps are used to clamp the workpiece to be processed.

[0018] By adopting the above technical solution, a clamp is set on the workbench so that the clamp can be clamped on the side wall of the copper plate, thereby fixing the copper plate relative to the workbench. When the tool falls and presses on the copper plate, lateral stress is generated on the copper plate and it is easy to slide on the workbench. By setting a clamp on the side wall of the copper plate, the chance of the copper plate moving can be reduced, so that the tool can accurately fall on the copper plate during processing, thereby improving the processing quality.

[0019] Optionally, a plurality of grooves are provided on the workbench, and the grooves are used for users to lift the workpiece.

[0020] By adopting the above technical solution, a groove is opened on the workbench. When the copper plate is laid flat on the workbench and clamped between the clamps, the copper plate cover is located above part of the groove. The user can insert the tool into the groove and lift the copper plate, thereby facilitating the user to remove the copper plate from the workbench.

[0021] Optionally, a support roller is rotatably connected to the mounting frame, and the support roller is tangent to the rotating shaft and supports the rotating shaft.

[0022] By adopting the above technical solution, the support roller is connected by rotating on the mounting frame so that the support roller can abut against the rotating shaft. When the rotating shaft rotates, the support roller can rotate with the rotating shaft. When the tool abuts against the copper plate, the support roller provides support to the rotating shaft, which can reduce the chance of the rotating shaft being deformed by force, thereby improving the positioning accuracy of the tool.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By arranging a tool on a rotating shaft, the tool can be adjusted in position by the rotating shaft. When the tool falls and presses a groove on the copper plate, the shape of the groove is the same as the angle between the cutting surface 1 and the cutting surface 2 on the tool. The user controls the tool to move upward and rotates the rotating shaft, thereby offsetting the tool. After the tool moves, it falls into the groove of the copper plate again, so that the groove of the copper plate can be processed into different shapes. The user can use a low-cost tool for processing. When the tool is worn, the user can grind the tool. The polished tool can continue to be used to press grooves on the copper plate, thereby reducing production costs.

[0025] 2. By setting a driving mechanism on the workbench and connecting the mounting frame to the driving mechanism, the user can lay the copper plate flat on the workbench, drive the tool to move through the driving mechanism, and drive the rotating shaft through the piezoelectric motor to rotate, so that the position of the tool can be adjusted, so that the tool can press down on the same position on the copper plate multiple times and process micro-prism structures of different shapes;

[0026] 3. By arranging a slide rail on the driving mechanism and arranging a supporting slider in the slide rail, the slide rail and the supporting slider play a supporting role. When the tool falls and abuts against the copper plate, the driving mechanism is subjected to stress, and the slide rail and the supporting slider can distribute the stress, reducing the degree of stress concentration on the power rail 1 and the power rail 2, thereby achieving the effect of protecting the power rail 1 and the power rail 2.

DETAILED DESCRIPTION

[0037] The present application is further described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] The present application discloses a high-precision deflection processing device for micro-prism structure, referring to Figure 1 and Figure 2 , including a rotating shaft 1, a tool 2, a piezoelectric motor 3 and a mounting bracket 6. The rotating shaft 1 is rotatably connected to the mounting bracket 6, and the tool 2 is detachably connected to the rotating shaft 1. The length direction of the tool 2 is perpendicular to the length direction of the rotating shaft 1. The shell of the piezoelectric motor 3 is fixed on the mounting bracket 6, and the output shaft of the piezoelectric motor 3 is coaxially connected to the rotating shaft 1. The user can adjust the position of the tool 2 on the rotating shaft 1 by controlling the rotation of the piezoelectric motor 3. By moving the mounting bracket 6 vertically, the tool 2 can press an indentation on the copper plate, thereby forming a plurality of polygonal grooves on the copper plate.

[0040] Reference Figure 1 and Figure 2 The mounting bracket 6 is rotatably connected to the spindle, which is used to be mounted on the processing equipment. The mounting bracket 6 and the spindle are connected to each other through the shaft seat. The rotating shaft 1 passes through the shaft seat and connects the spindle and the mounting bracket 6. The mounting bracket 6 has a cylindrical structure, and the shaft seat is mounted on one end surface of the mounting bracket 6. The mounting bracket 6 has a mounting groove 62 on the end surface away from the spindle. The mounting groove 62 is used to mount the tool 2. The mounting bracket 6 is provided with multiple bolts. The bolts pass through the mounting bracket 6 and are inserted into the mounting groove 62, so that the tool 2 can be fixed in the mounting groove 62 by the bolts.

[0041] Reference Figure 1 and Figure 2The tool 2 is provided with a cutting surface 1 21 and a cutting surface 22. Both the cutting surface 1 21 and the cutting surface 2 22 are planes, and the cutting surface 1 21 and the cutting surface 2 22 are set at an angle. When the mounting bracket 6 moves for the first time, the cutting head of the tool 2 contacts the copper plate, pressing out a groove on the copper plate with the same angle as the cutting surface 1 21 and the cutting surface 2 22. Then the mounting bracket 6 moves away from the copper plate, and the piezoelectric motor 3 drives the rotating shaft 1 to rotate, causing the tool 2 to rotate along the intersection line of the cutting surface 1 21 and the cutting surface 2 22 as the axis. At this time, the mounting bracket 6 moves again, allowing the tool 2 to contact the groove of the copper plate again. The two processes form a groove on the copper plate. The angle of the groove cross section depends on the moving position of the tool 2. The user can use the tool 2 to process micro-prism reflective structures with different angles, without the need to use a customized tool with the intersection angle of the cutting surface 1 21 and the cutting surface 2 22 being the micro-prism angle, thereby reducing the processing cost. By installing a piezoelectric motor 3 at the end of the rotating shaft 1, the piezoelectric motor 3 can drive the rotating shaft 1 to rotate with high precision, which in turn enables the rotating shaft 1 to drive the tool 2 to rotate precisely, achieving high-precision micro-edge angles on the copper plate. When the tool 2 is installed on the rotating shaft 1, the intersection line of the cutting surface 1 21 and the cutting surface 2 22 is parallel to the rotating shaft 1.

[0042] In other embodiments, the spindle can be installed on a machine tool so that the machine tool drives the spindle to rotate. During the rotation of the mounting frame 6 driven by the spindle, the position of the tool 2 can be adjusted by the piezoelectric motor 3, so that the tool 2 can complete the groove cutting work of a specific shape.

[0043] Example 2

[0044] The present application discloses a high-precision deflection processing device for micro-prism structure, referring to Figure 3 and Figure 4 The difference from Example 1 is that the tool holder 11 is fixed to the middle of the rotating shaft 1. The tool holder 11 is a frame structure, and the tool 2 is connected to the rotating shaft 1 by inserting the tool holder 11. When the tool 2 is installed on the tool holder 11, the length direction of the tool 2 is perpendicular to the length direction of the rotating shaft 1.

[0045] Reference Figure 5 ,and Figure 6 A driving mechanism 5 is provided on the mounting frame 6, and a workbench 4 is provided on the driving mechanism 5. The workbench 4 is used to place the copper plate to be processed. The driving mechanism 5 is used to drive the mounting frame 6 to move and fall above the workbench 4, so that the tool 2 can be pressed on the copper plate to process the micro-ridge structure on the copper plate.

[0046] Reference Figure 7The workbench 4 is set horizontally, and the copper plate is laid flat on the workbench 4. A plurality of clips 41 are fixed on the workbench 4. The clips 41 are used to clip on the side wall of the copper plate. The clips 41 have the effect of fixing the copper plate, so that the copper plate can remain fixed when the tool 2 falls and processes the copper plate, thereby improving the processing quality of the copper plate. A plurality of grooves 42 are provided on the workbench 4. The grooves 42 are located on the lower side of the edge of the copper plate. When the copper plate is set on the workbench 4, the edge of the copper plate is covered on the grooves 42, and one side of the grooves 42 extends out of the copper plate. The user can lift the copper plate through the grooves 42, thereby conveniently picking up the processed copper plate from the workbench 4.

[0047] Reference Figure 8 and Figure 9 The drive mechanism 5 includes a hydraulic cylinder 51, a lifting plate 52, a power rail 1 53, a sliding plate 54, and a power rail 2 55. The hydraulic cylinder 51 is vertically mounted on the workbench 4. The cylinder body of the hydraulic cylinder 51 is fixed to the workbench 4, and the piston rod of the hydraulic cylinder 51 is fixed to the lifting plate 52. The lifting plate 52 is arranged parallel to the workbench 4. The power rail 1 53 can be a pneumatic or electric slide. The stator of the power rail 1 53 is fixed to the lifting plate 52, and the mover of the power rail 1 53 is slidably connected to the stator. The sliding plate 54 is fixedly connected to the mover of the power rail 1 53 and is parallel to the lifting plate 52. The stator of the power rail 2 55 is fixed to the sliding plate 54, and the mover is connected to the mounting frame 6. The power rail 1 53 is perpendicular to the power rail 2 55. The hydraulic cylinder 51 is used to drive the mounting frame 6 to move back and forth vertically. The power rail 1 53 and the power rail 2 55 enable the mounting frame 6 to slide in different directions, thereby adjusting the position of the tool 2.

[0048] Reference Figure 8 and Figure 9 The lifting plate 52 and the sliding plate 54 are provided with a support block 56 and a slide rail 57. The support block 56 is fixed to the sliding plate 54 or the mounting frame 6. The support block 56 is slidably connected to the slide rail 57. The slide rail 57 is fixed to the lifting plate 52 or the sliding plate 54. The support block 56 on the sliding plate 54 is slidably connected to the slide rail 57 on the lifting plate 52. The support block 56 on the mounting frame 6 is slidably connected to the slide rail 57 on the sliding plate 54. The support block 56 and the slide rail 57 further enhance the overall structural strength of the drive mechanism 5. When the tool 2 abuts against the copper plate, the entire drive mechanism 5 is subjected to stress. The support block 56 and the slide rail 57 can withstand the stress, reducing the probability of stress concentration on the power rail 1 53 and the power rail 2 55, thereby extending the service life of the drive mechanism 5.

[0049] Reference Figure 8 and Figure 9The mounting frame 6 is provided with a support roller 61, which is rotatably connected to the mounting frame 6 and abuts the rotating shaft 1. When the tool 2 abuts the copper plate, the rotating shaft 1 is subjected to stress. The support roller 61 provides support for the rotating shaft 1, reducing the probability of deformation of the rotating shaft 1 and ensuring the positioning accuracy of the tool 2.

[0050] The implementation principle of the embodiment of the present application is: by setting a tool 2 on the rotating shaft 1, using a piezoelectric motor 3 to drive the rotating shaft 1 to rotate, the effect of controlling the position of the tool 2 is achieved, and by making the tool 2 fall on the same position on the copper plate multiple times, the tool 2 can open micro-rib grooves on the copper plate. The user can adjust the position of the tool 2 through the piezoelectric motor 3 and the drive mechanism 5, so that the tool 2 can open micro-rib grooves of different shapes, thereby reducing the cost of customized tools.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
