Description

Technical Field

[0001] This application relates to the field of product fixtures, and in particular to a precision engraving alignment tooling. Background Art

[0002] Precision engraving alignment tooling is widely used in various fields that require high-precision machining, such as aerospace, automotive manufacturing, mold manufacturing, electronic product manufacturing, etc. In these fields, the accuracy and surface quality of workpieces often have an important impact on the overall performance and service life of products. Therefore, using precision engraving alignment tooling for machining can significantly improve the machining accuracy and surface quality of products and meet the industry's demand for high-precision machining. However, when the engraving device processes workpieces, it is easy to cause the workpieces to vibrate and shift, thereby reducing the machining effect.

[0003] For example, the precision engraving tooling positioning fixture with the application number CN202222369730.1 includes a tooling body. The tooling body has a fixed body and an elastic body. Both the fixed body and the elastic body have through connecting half-holes near the bottom. Both the fixed body and the elastic body have through positioning half-holes at one end of the connecting half-holes away from the bottom. The upper end of the tooling body has an inwardly recessed positioning groove; a positioning block that can extend into the positioning groove and is in clearance fit with the side wall of the positioning groove. After the positioning block is in clearance fit with the side wall, it abuts against the end of the positioning half-hole. The following are the deficiencies of the above equipment during actual use:

[0004] This device fixes the workpiece in the positioning groove and cooperates with the positioning rod to rotate the body, and interacts with the engraving device to perform engraving. However, when the engraving tool or laser end of the engraving device contacts the workpiece, it will cause the workpiece to vibrate slightly, easily deviate from the preset engraving pattern, reduce the machining accuracy, and affect the surface quality. Summary of the Utility Model

[0005] In order to improve the problem that conventional precision engraving tooling is prone to cause workpieces to vibrate during machining, reduce the machining accuracy, and affect the surface quality, this application provides a precision engraving alignment tooling.

[0006] A precision engraving alignment tooling provided by this application adopts the following technical solutions:

[0007] A precision engraving alignment tooling includes a base. A plurality of mounting seats for connecting negative pressure are arranged on the top of the base. Fixing plates are arranged on the tops of the plurality of mounting seats. Engraving modules for precision engraving treatment are arranged on the tops of the plurality of fixing plates;

[0008] On both sides of the mounting base at the top of the base, there are movable plates. At the positions of multiple mounting bases on the tops of the two movable plates, fixture toolings are fixedly installed. One side of two diagonally opposite fixture toolings abuts against the side surface of the engraving module and is fixed;

[0009] On one side of each of the multiple fixture toolings away from the connecting bump, there is an inclined surface. When the multiple fixture toolings are away from the fixed plate, the adjacent two inclined surfaces form an abutment.

[0010] By adopting the above technical solution, the fixed plate transmits suction force and diffuses it to the bottom surface of the engraving module, thereby fixing the engraving module on the top of the fixed plate to form a longitudinal fixation. Cooperating with the two movable plates to drive the fixture toolings to clamp both sides of the engraving module to form a longitudinal fixation, preventing the engraving module from jittering during processing. When the multiple fixture toolings are unfolded, the inclined surfaces of the adjacent two fixture toolings abut against each other, thereby forming a limit and facilitating the operator to observe and stop the movement of the fixture tooling.

[0011] Preferably, on the side surfaces of the multiple mounting bases, negative pressure interfaces are fixedly installed, and at the centers of the tops of the multiple mounting bases, ventilation grooves communicating with the multiple negative pressure interfaces one by one are opened.

[0012] By adopting the above technical solution, the negative pressure interfaces are docked with an external negative pressure device to generate suction force and transmit the suction force into the ventilation grooves.

[0013] Preferably, on the tops of the multiple fixed plates, expansion grooves are opened, and at the centers of the bottoms of the multiple expansion grooves, ventilation holes communicating with the multiple ventilation grooves one by one are penetrated.

[0014] By adopting the above technical solution, the ventilation holes transmit the negative pressure generated in the ventilation grooves to the expansion grooves. The expansion grooves are in a cross shape at the bottom of the engraving module, applying a suction force to the engraving module to maintain fixation.

[0015] Preferably, on the side surfaces of the multiple fixed plates, ring blocks are fixedly installed around them, and arc-shaped surfaces are arranged at the corners of the multiple ring blocks.

[0016] By adopting the above technical solution, the ring blocks protrude from the fixed plate, and the arc-shaped surfaces on the surfaces of the ring blocks are attached to the inner walls of the fixture toolings for easy abutment, forming the fixation of the fixed plate.

[0017] Preferably, on one side surface of each of the multiple fixture toolings close to the arc-shaped surface, disassembly holes are opened.

[0018] By adopting the above technical solution, the disassembly holes penetrate through the fixture toolings, thereby connecting the connection points between the fixture toolings and the fixed plate, facilitating the disassembly of the engraving module.

[0019] Preferably, on one side of the outer surface of each of the plurality of jig toolings close to the moving plate, a connecting convex block is protruding, and the bottom of the connecting convex block is fixedly connected to the moving plate.

[0020] By adopting the above technical solution, the connecting convex block protrudes outwards, so that it is located outside the range of the mounting seat, which is convenient for connecting and moving with the moving plate and prevents dislocation.

[0021] Preferably, a rectangle is formed between two opposite jig toolings.

[0022] By adopting the above technical solution, a rectangular space is formed between two opposite jig toolings, which fits the shape of the engraving module and is convenient for fixing.

[0023] Preferably, the plurality of jig toolings are in contact with the ring block, so that there is a gap between the jig tooling and the fixed plate, which is convenient for fixing the engraving module.

[0024] By adopting the above technical solution, the ring block protrudes from the fixed plate. When the jig tooling is in contact with the ring block, there is a gap space reserved from the fixed plate, which is convenient for air discharge and assists in fixing the engraving module.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By using the jig tooling in contact with the ring block, the engraving module is horizontally fixed. The negative pressure interface receives negative pressure to generate suction, and the suction is diffused to the bottom of the engraving module through the expansion slot to form vertical fixation, effectively preventing the engraving module from shaking during the processing and improving the processing accuracy and the surface quality of the engraving module.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following is combined with the attached Figure 1 -Figure 4 Further detailed description of the present application will be given below.

[0033] An embodiment of the present application discloses a fine carving alignment tooling.

[0034] Refer to Figure 1 and 3 . A fine carving alignment tooling includes a base 1. A plurality of mounting seats 2 are fixed to the upper end surface of the base 1 by screws. And a negative pressure interface 7 is fixedly provided on one side of the outer surface of each of the plurality of mounting seats 2. A ventilation groove 8 is provided at the center position of the upper end surface of the mounting seat 2. And the ventilation groove 8 penetrates through the inside of the mounting seat 2 to communicate with the negative pressure interface 7. A fixing plate 3 is fixedly provided on the upper end surface of each of the plurality of mounting seats 2. A cross-shaped expansion groove 9 is provided on the upper end surface of each of the plurality of fixing plates 3. A ventilation hole 10 is provided through the fixing plate 3 at the cross center position of the expansion groove 9. And the ventilation hole 10 has the same width as the ventilation groove 8 and is centered. A ring block 11 is fixedly provided around the bottom of the outer surface of each of the plurality of fixing plates 3. And the positions of the ring block 11 at the four corner inflection points of the fixing plate 3 are all provided with arc surfaces 12.

[0035] It should be noted that the length of the base 1 and the number of the mounting seats 2 are adjusted according to actual production requirements. And the negative pressure interface 7 is docked with an external negative pressure generating device to transmit suction force.

[0036] The plurality of mounting seats 2 are fixedly provided on the surface of the base 1 to form an integral fixation, which is convenient for the installation of the fixing plate 3. At the same time, the negative pressure interface 7 transmits the external negative pressure suction force and conveys the suction force into the ventilation groove 8. The ventilation groove 8 diffuses the received suction force into the expansion groove 9 through the ventilation hole 10, so as to provide an adsorption force for the subsequent fixation of the engraving module 4. And the ring block 11 surrounds the fixing plate 3 to facilitate the fitting with the subsequent fixture tooling 6, so as to maintain the fixing effect.

[0037] Refer to Figure 1 and 2 Figure 3. On both sides of the mounting seats 2 on the top of the base 1, moving plates 5 are movably arranged. And both ends of the two moving plates 5 are fixedly connected to an external driving mechanism to perform translation. Fixture toolings 6 are fixedly provided at the positions of the upper end surfaces of the two moving plates 5 aligned with the plurality of fixing plates 3, so that each fixing plate 3 corresponds to two fixture toolings 6 respectively (as shown in Figure Figure 2 ). The fixture tooling 6 is integrally L-shaped. And the inner wall of the L-shape is arc-shaped. The arc-shaped inner wall of the fixture tooling 6 has the same radian as the arc surface 12. One side of the fixture tooling 6 close to the moving plate 5 protrudes outward to be a connecting convex block 14. The connecting convex block 14 is outside the range of the fixing plate 3. And the bottom of the connecting convex block 14 is fixedly connected to the upper end surface of the moving plate 5. At the same time, the other side surface of the fixture tooling 6 relative to the connecting convex block 14 is provided with an inclined surface 15.

[0038] It should be noted that the fixture tooling 6 is provided with an inclined surface 15 on the other end side surface relative to the connecting bump 14, and when multiple fixture toolings 6 are unfolded, the adjacent two inclined surfaces 15 abut against each other (as Figure 1 shown). At the same time, when the fixture tooling 6 clamps, the arc-shaped inner wall of the fixture tooling 6 abuts and fits with the ring block 11, and a gap is formed between the fixture tooling 6 and the fixing plate 3.

[0039] The two moving plates 5 move towards each other. The moving plate 5 drives the connecting bump 14, forming the moving plate 5 driving two rows of fixture toolings 6 to perform synchronous translation, so that the arc-shaped inner wall of the fixture tooling 6 abuts against the outer surface and the arc-shaped surface 12 of the ring block 11, thereby clamping and fixing the subsequent engraving module 4. At the same time, multiple fixture toolings 6 move in the opposite direction and unfold, so that the adjacent inclined surfaces 15 abut against each other, thereby forming a limit, and facilitating personnel to observe and stop the movement of the moving plate 5.

[0040] Refer to Figure 1 、 2 、4. On the upper end surfaces of multiple fixing plates 3, engraving modules 4 are movably abutted. The width of the engraving module 4 is the same as the width of the fixing plate 3, and the engraving module 4 is centered with the fixing plate 3. When the fixture tooling 6 clamps, the outer surface of the engraving module 4 abuts against the arc-shaped inner wall of the fixture tooling 6, and the engraving module 4 covers the gap between the fixture tooling 6 and the fixing plate 3. At the same time, a disassembly hole 13 is formed through the center of the arc-shaped inner wall of multiple fixture toolings 6. The disassembly hole 13 penetrates through the upper and lower ends of the fixture tooling 6, so that the connection point between the middle of the arc-shaped surface 12 and the inner wall of the fixture tooling 6 communicates with the outside.

[0041] Two fixture toolings 6 abut against the ring block 11, forming an overall groove between the fixture tooling 6 and the fixing plate 3, and the inner wall of the formed groove abuts against the side surface of the engraving module 4 to form a fixation. Also, the position of the outer surface of the engraving module 4 located on the arc-shaped inner wall of the fixture tooling 6 is also arc-shaped, so that the connection point between the engraving module 4 and the fixture tooling 6 fits, preventing the engraving module 4 from jittering within the fixture tooling 6.

[0042] The implementation principle of the precision engraving alignment tooling in the embodiment of the present application is as follows: When using this device, the two fixture toolings 6 corresponding to each fixing plate 3 are in the unfolded state. Then, the operator places the engraving module 4 to be engraved on the upper surface of the fixing plate 3. Then, the driving mechanism is started, so that the driving mechanism drives the two moving plates 5 to move in the opposite direction, and further the moving plate 5 drives the connecting bump 14, so that the two rows of fixture toolings 6 move towards each other, thereby pushing the engraving module 4 with a certain offset. Finally, the inner walls of the two fixture toolings 6 corresponding to each fixing plate 3 abut against the outer surface of the ring block 11, and the engraving module 4 is pushed to a state centered with the fixing plate 3. At the same time, the two fixture toolings 6 also form a clamping connection to the engraving module 4;

[0043] Then, the operator starts the external negative pressure generating device to generate negative pressure to form suction force. The suction force is transmitted from the negative pressure interface 7 into the ventilation groove 8, and then docks with the ventilation holes 10 and diffuses into the extension groove 9, so as to act the suction force on the bottom of the engraving module 4, adsorb the engraving module 4 on the upper surface of the fixed plate 3, thereby forming the horizontal and vertical fixation of the engraving module 4, facilitating the operator to start the engraving device to perform fine engraving operations on the engraving module 4.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
