Waveguides can transmit high-frequency electromagnetic signals within a certain range and are widely used in fields such as wireless communication, radar, and microwave ovens.
[0003] After the waveguide structural parts go through processing procedures such as milling, drilling, and tapping, a laser engraving machine is required to perform laser engraving on the surface of the structural parts for marking. The laser engraving machine includes a workbench and a laser generator. The structural parts will be placed on the workbench with the side to be processed facing the laser generator.
[0004] The workbench of a small metal laser engraving machine is usually a flat tabletop, and only positioning lines are provided on the tabletop. When engraving, the risk of workpiece displacement is relatively high, and once displacement occurs, the deviation between the position after secondary positioning and the initial position cannot be ignored. Summary of the Invention
[0005] In order to improve the above problems, the present application provides a laser engraving machine for processing waveguide structural parts.
[0006] The laser engraving machine for processing waveguide structural parts provided by the present application adopts the following technical solutions:
[0007] A laser engraving machine for processing waveguide structural parts includes a workbench and a laser generator. A fixture mechanism is provided on the workbench. A plurality of positioning jacks are opened on the workbench, and the plurality of positioning jacks are arranged in a horizontal and vertical array on the workbench. The fixture mechanism includes a plurality of fixture blocks and positioning rods, and the positioning rods pass through the fixture blocks and are inserted into the positioning jacks.
[0008] By adopting the above technical solutions, according to the specific shape of the workpiece, the fixture blocks are arranged on the workbench, so that the fixture blocks can provide support for the side edges of the workpiece, and during the processing, the workpiece is not likely to undergo lateral displacement.
[0009] Preferably, the fixture block includes a fixed block, the positioning rod is a bolt, the bolt passes through the fixed block and is inserted into the positioning jack, and the bolt is threadedly connected to the workbench. The fixed block abuts against the tabletop of the workbench, and the workpiece abuts against the side wall of the fixed block.
[0010] By adopting the above technical solutions, the positioning rod is threadedly connected to the workbench, and the connection stability is higher.
[0011] Preferably, the fixture block also includes a base block, and an adjustment block is slidably provided on one side of the base block. The moving direction of the adjustment block is parallel to the table surface of the workbench. The adjustment block moves close to or away from the fixed block, and the adjustment block applies abutment force to the workpiece. A control component for controlling the sliding of the adjustment block is provided between the base block and the adjustment block.
[0012] By adopting the above technical solution, the movement of the adjusting block can apply abutting force to the workpiece, and the workpiece can be clamped and fixed in cooperation with the fixing block.
[0013] Preferably, a fitting body is detachably provided on a side of the adjustment block facing the workpiece, and the fitting body is in contact with a side wall of the workpiece.
[0014] By adopting the above technical solution, the shape of the fitting body is made according to the shape of the side edge of the workpiece, and has good fit with the surface of the workpiece, thereby improving the stability of clamping and fixing the workpiece.
[0015] Preferably, a mating rod is fixedly connected to the mating body, and a mating hole for inserting the mating rod is provided on the side of the adjustment block facing the workpiece, and the cross-sections of the mating rod and the mating hole are both non-circular.
[0016] By adopting the above technical solution, the matching rod is inserted into the matching socket, and the matching body and the adjustment block are connected to each other and cannot be rotated, which is convenient for operation.
[0017] Preferably, the control component includes a locking pin and a locking spring, a plurality of locking holes are opened on the base block, and the plurality of locking holes are arranged in an array along the sliding direction of the adjusting block. The locking pin and the adjusting block are slidingly connected, and the sliding direction is parallel to the hole depth direction of the locking hole. One end of the locking spring is connected to the adjusting block, and the other end is connected to the locking pin. When the locking pin and a single locking hole are coaxial, the locking spring applies a thrust to the locking pin to make it enter the locking hole.
[0018] By adopting the above technical solution, when the adjusting block moves to the point where the locking pin and a single locking hole are coaxial, the locking spring applies a thrust to the locking pin to cause it to enter the locking hole. At this time, the locking pin passes through the adjusting block and the base block at the same time, and the adjusting block and the base block cannot move relative to each other, that is, the two are relatively fixed.
[0019] Preferably, a pushing block is provided in the mating socket, and the pushing block slides relative to the mating socket and the adjusting block.

First, determine the position of the first adjustment hole, and then rotate the base block around the first adjustment hole to adjust the angle of the base block. Since the second adjustment hole is an elongated hole, during the rotation of the base block around the first adjustment hole, as long as the open end of the positioning jack falls into the second adjustment hole, the positioning rod can be inserted to fix the base block at this angle.
[0023] Preferably, clamping edges are formed on both sides of the opening of the second adjustment hole on the base block. The length direction of the clamping edges is the same as the length direction of the second adjustment hole. A support frame is arranged on the base block, and a clamping groove is formed on the support frame. The length of the clamping groove is smaller than the length of the clamping edges. The support frame is clamped with the base block through the cooperation of the clamping edges and the clamping groove. A plurality of displacement holes for the positioning rod to pass through are formed on the support frame, and the plurality of displacement holes are arranged along the length direction of the second adjustment hole.

Detailed implementation manners
[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.
[0033] The embodiments of the present application disclose a laser engraving machine for processing waveguide structural parts. As Figure 1 shown, it includes a workbench 1 and a laser generator 11. The workbench 1 is for placing the workpiece 2 thereon, and the laser generator 11 is used for laser engraving the upper surface of the workpiece 2. A fixture mechanism 3 is provided on the workbench 1, and the fixture mechanism 3 is used for fixing the position of the workpiece 2 located on the tabletop of the workbench 1.
[0034] As Figure 1 shown, a plurality of positioning jacks 12 are opened on the workbench 1. The plurality of positioning jacks 12 are arranged in a horizontal and vertical array on the workbench 1, and the depth direction of the positioning jack 12 is perpendicular to the tabletop of the workbench 1. The fixture mechanism 3 includes a plurality of fixture blocks 31 and a positioning rod 37. The fixture block 31 includes a fixing block 311 and a base block 312. The positioning rod 37 is a bolt, and the positioning jack 12 is a threaded hole. The positioning rod 37 will pass through the fixture block 31 and be screwed into the positioning jack 12, thereby fixing each fixture block 31. The bottom of the fixture block 31 abuts against the tabletop of the workbench 1. In this embodiment, there are two fixing blocks 311. The workpiece 2 is approximately rectangular in shape. The fixing blocks 311 are strip-shaped, and the length directions of the two fixing blocks 311 are perpendicular to each other. Two adjacent side surfaces of the workpiece 2 respectively abut against the side walls of the two fixing blocks 311.
[0035] As Figure 1 and 2As shown, the base block 312 is also strip-shaped, with one end facing the workpiece 2. A regulating block 32 is slidably arranged at the end of the base block 312 facing the workpiece 2. The moving direction of the regulating block 32 is parallel to the tabletop of the workbench 1 and consistent with the length direction of the base block 312. When the regulating block 32 moves, it approaches or moves away from the fixed block 311. A mating body 34 is detachably arranged on the side of the regulating block 32 facing the workpiece 2. The shape of the mating body 34 is customized according to the side contour shape of the workpiece 2. Taking the cuboid workpiece 2 as an example, the mating body 34 is L-shaped, and the angled part of the mating body 34 will fit and abut against the side edge of the workpiece 2 away from the fixed block 311. The tendency of the regulating block 32 to move closer to the workpiece 2 can exert a pressing force on the workpiece 2 through the mating body 34, and jointly clamp the workpiece 2 with the fixed block 311.
[0036] As Figure 2 and 3 shown, a control assembly 33 for controlling the sliding of the regulating block 32 is provided between the base block 312 and the regulating block 32. The control assembly 33 includes a locking pin 331 and a locking spring 332. A plurality of locking holes 3123 are formed in the base block 312. The depth direction of the locking holes 3123 is the vertical direction, and the plurality of locking holes 3123 are arranged in an array along the sliding direction of the regulating block 32; the locking pin 331 is slidably connected to the regulating block 32, and the sliding direction is parallel to the depth direction of the locking holes 3123. One end of the locking spring 332 is connected to the regulating block 32, and the other end is connected to the locking pin 331. In the natural state, when the regulating block 32 moves to make the locking pin 331 coaxial with a single locking hole 3123, the locking spring 332 exerts a thrust on the locking pin 331 to make it enter the locking hole 3123. At this time, the locking pin 331 passes through both the regulating block 32 and the base block 312, and the regulating block 32 and the base block 312 cannot move relative to each other, that is, the two are relatively fixed.
[0037] As Figure 1 、 2As shown in FIGS. 3, on the side of the ligand 34 facing away from the workpiece 2, a mating insertion rod 341 is fixedly connected. On the side of the adjustment block 32 facing the workpiece 2, a mating insertion hole 321 for the mating insertion rod 341 to insert into is provided. The length direction of the mating insertion hole 321 is parallel to the moving direction of the adjustment block 32 relative to the base block 312. The mating insertion hole 321 and the mating insertion rod 341 are in hole-shaft fit, and their cross-sections are both square. A pushing block 361 is arranged in the mating insertion hole 321. The pushing block 361 slides relative to the adjustment block 32 through the mating insertion hole 321. On the side of the pushing block 361 facing away from the ligand 34, a pushing screw 36 is fixedly connected. The length direction of the pushing screw 36 is parallel to the length direction of the mating insertion hole 321. A pushing disc 35 is rotatably arranged on the adjustment block 32. The pushing screw 36 is threadedly connected to the pushing disc 35 coaxially. By rotating the pushing disc 35, the pushing screw 36 and the pushing block 361 can move. When the pushing block 361 moves towards the mating insertion rod 341, it generates a thrust on the mating insertion rod 341, and the ligand 34 tightly abuts against the side of the workpiece 2, thereby clamping and fixing the workpiece 2.
[0038] As Figure 2 and 3 shown, on the base block 312, a first adjustment hole 3121 and a second adjustment hole 3122 for the positioning rod 37 to insert into are provided. The first adjustment hole 3121 is located between the second adjustment hole 3122 and the workpiece 2. According to the shape of the side contour of the workpiece 2, in addition to the shape of the ligand 34, the moving directions of the adjustment block 32 and the ligand 34 also need to be adjusted as the case may be, that is, the length direction of the base block 312. The first adjustment hole 3121 is coaxial with one of the positioning insertion holes 12. The length direction of the second adjustment hole 3122 is the radial direction of the first adjustment hole 3121, that is, the length direction of the second adjustment hole 3122 is parallel to the length direction of the base block 312. When installing the base block 312, first determine the position of the first adjustment hole 3121, and then rotate the base block 312 with the first adjustment hole ³¹²¹ as the center to adjust the angle of the base block 312. Since the second adjustment hole 3122 is a long hole, during the process of the base block 312 rotating around the first adjustment hole 3121, as long as the open end of one of the positioning insertion holes 12 falls into the second adjustment hole 3122, the positioning rod 37 can be inserted to keep the base block 312 fixed at this angle.
[0039] As Figure 1 and 3As shown in the figure, on the base block 312 and on both sides of the orifice of the second adjustment hole 3122, there are formed clamping edges 3124, and the length direction of the clamping edges 3124 is the same as the length direction of the second adjustment hole 3122. In order to improve the structural strength of the base block 312 at the second adjustment hole 3122, a support frame 4 is provided on the base block 312. Two clamping grooves 41 are formed along the length direction of the support frame 4 itself. The length of the support frame 4 is less than the length of the second adjustment hole 3122, and the length of the clamping groove 41 is less than the length of the clamping edge 3124. The support frame 4 is clamped with the base block 312 through the cooperation of the clamping edge 3124 and the clamping groove 41. At this time, the support frame 4 straddles above the second adjustment hole 3122 to support the two clamping edges 3124, making it difficult for the clamping edges 3124 and the base block 312 to deform. A plurality of displacement holes 42 for the positioning rod 37 to pass through are formed on the support frame 4, and the plurality of displacement holes 42 are arranged along the length direction of the second adjustment hole 3122.
[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. 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.
