Description

Technical Field

[0001] The invention relates to the technical field of carving knife production, and in particular to a convenient positioning tool for carving knife production. Background Art

[0002] During the knife production process, precise positioning is one of the key factors to ensure the quality and performance of the carving knife. After the carving knife is processed, the tool and the handle need to be assembled.

[0003] For example, a positioning tool for tool production with publication number CN220030009U places the tool on a first arc seat, and the hydraulic rod drives the second arc seat to move downward, and the second arc seat drives the guide wheel to slide in the frame. At the same time, the second arc seat presses and fixes the tool on the first arc seat. The frame can be driven up and down by an electric cylinder to adjust the height of the tool. However, in actual use, the engraving tool needs to be assembled with the handle after production, and the engraving tool is fixed during the assembly process. Currently, when assembling the engraving tool and the handle, the tool needs to be fixed first, and then the tool and the handle are assembled with interference fit, and the tool is inserted into the handle so that when the tool and the handle are assembled, the tool is fixed. During assembly, the operations need to be performed separately. The assembly continuity of the handle and the tool is poor. In the continuous production process, the combination efficiency of the tool and the handle is not high, and when fixing the tool, the tool can only be clamped in the up and down directions. If it is clamped on both sides of the tool, the contact area between the tool and the positioning structure is small, and the positioning effect cannot be guaranteed. If the tool is positioned at one end of the tool, the blade is easily damaged during the subsequent assembly process. The tool not only needs to be fixed but also the handle needs to be moved or the tool needs to be inserted for assembly. During the assembly process, the shape of the engraving knife is different due to different uses. Reliable positioning between the tool and the positioning tool cannot be guaranteed, which easily affects the assembly effect and has certain usage defects.

[0004] Therefore, we proposed a convenient positioning tool for carving knife production to solve the above problems. Summary of the Invention

[0027] By adopting the above technical solution, the upward movement of the sliding frame can push the limiting plate to rotate, so that the tool handle can be fixed.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: the convenient positioning tool for the production of the carving knife is provided with a positioning component on one side of the top of the workbench, so that the carving knife can be positioned quickly and conveniently, and the carving knife can be assembled with the knife handle after being positioned, thereby saving operation time and improving the continuity of assembly. In addition, the knife can be reliably positioned during the assembly process, avoiding displacement of the knife during the insertion into the knife handle, thereby improving convenience and practicality;

[0029] 1. When fixing the tool, if the tool is a round carving tool or a triangular carving tool, place the two bottom edges of the tool on two rubber pads, and place the knife handle in the placement slot on the top of the placement table. Then, the electric cylinder can be started to drive the movable plate to move down. After the movable plate moves down, the positioning seat can be driven down. The positioning seat moves down so that the movable seat abuts against the top of the tool. After that, the positioning seat no longer moves, and the movable plate continues to move to rotate the connecting plate, and can push the movable seat to slide on the support rod, so that the tool can be moved after being positioned by the positioning seat and the movable seat. During the movement, the movable seat drives the rollers between the mounting frames to rotate, and the rollers can push the movable plate up under the action of the inclined plate, so that the movable rod moves and the compression spring is deformed, thereby moving the rubber arc plate upward, so that the rubber arc plate can fit with the bottom of the tool, and then as the movable seat moves, the rubber arc plate can be moved through the rubber arc The plate further positions the tool, improving positioning reliability. If the cross section of the tool is rectangular, the positioning bolt can be removed and the support plate can be moved, so that the adjustment plate can be driven to move, and then the inclined plate can be rotated, so that the movable frame slides on the support plate, and the slope of the inclined plate can be adjusted. Then, the positioning bolt is inserted into another positioning hole to position the support plate, thereby shortening the displacement of the movable rod after the movable seat moves, which is convenient for adjustment according to the type of tool, and then the tool can be inserted into the tool handle as the movable seat moves, and assembled through the interference fit of the tool and the tool handle. The positioning component makes it possible to quickly and conveniently position the engraving tool, and the engraving tool can be assembled with the tool handle after positioning, saving operation time and improving assembly continuity. In addition, the tool can be reliably positioned during the assembly process to avoid displacement of the tool during insertion into the tool handle, thereby improving convenience and practicality.

[0030] 2. The movable seat moves the movable plate during the movement process. After the movable plate moves, the steel wire rope can be pulled to move. The steel wire rope is gradually straightened to pull the movable frame to move. The elastic potential energy of the telescopic spring is less than the adaptive spring, so that after the movable frame moves, the telescopic spring is deformed, and then the two positioning bars are in contact with the tool. If the movable frame continues to move after the positioning bar contacts the tool, the movable frame can slide on the two sliding rods and stretch the adaptive spring. The tool can be further positioned through the two positioning bars, further improving the positioning reliability. The two positioning bars move in the same displacement, which can calibrate the tool to avoid the tool offset on the movable seat, avoid affecting the subsequent assembly effect, and improve practicality.

[0031] 3. The movable seat can drive the U-shaped frame to move during the movement, so that the sliding plate can be driven to slide on the limit frame. After the sliding plate moves, it can drive the push plate to move. The push plate can push the ball to rotate through the slope, so that the sliding frame can be lifted up. The sliding frame can push the limit plate to rotate between the vertical frames, so that the torsion spring is deformed, so that the limit plate can cover the top of the tool handle, so that the tool handle is tightly attached to the placement slot, so that the tool handle can be fixed, avoiding the tool handle from shifting during the assembly process and improving the accuracy of assembly.

[0047] The positioning seat 207 is hinged to the side of the connecting plate 205 away from the movable plate 203. A movable seat 208 is provided below the positioning seat 207. Positioning rods 2071 are symmetrically installed on both sides of the positioning seat 207, and positioning blocks 2072 are symmetrically installed above both sides of the movable seat 208. At the same time, the positioning rods 2071 and the positioning blocks 2072 are slidably connected.

[0048] Two sets of support rods 209 are symmetrically and slidably connected inside the movable seat 208, and one end of each set of support rods 209 is fixedly connected to the placement table 102, and the other end of each set of support rods 209 is fixedly installed with a vertical plate 210, and the vertical plate 210 is fixedly connected to the workbench 1. A rectangular groove 212 is opened on the top of the movable seat 208, and a rubber pad 211 is symmetrically installed on the top of the movable seat 208. A movable rod 213 is symmetrically and slidably connected to the upper part of the movable seat 208;

[0049] A rubber arc plate 2131 is fixedly mounted on the top of the two movable rods 213, and a movable plate 215 is fixedly mounted on the bottom of the two movable rods 213. Compression springs 214 are sleeved on the outside of the two movable rods 213 above the movable plate 215. The two ends of the compression spring 214 are respectively fixedly connected to the movable seat 208 and the movable plate 215. Mounting brackets 216 are symmetrically mounted on the bottom of the movable plate 215, and a roller 217 is rotatably connected between the two mounting brackets 216.

[0050] A support platform 218 is fixedly installed on the top of the workbench 1 below the movable seat 208, and an inclined plate 219 is hinged on the upper side of one side of the support platform 218, and an adjustment plate 220 is hinged on the side of the inclined plate 219 away from the support platform 218, and a movable frame 221 is fixedly installed on one side of the adjustment plate 220, and the interior of the movable frame 221 is slidably connected to a support plate 222, and the interior of the support plate 222 is slidably connected to a fixed plate 224, and both sides of the fixed plate 224 are fixedly installed with mounting plates 223, and the two mounting plates 223 are fixedly connected to the workbench 1;

[0051] A support block 225 is fixedly installed below one side of the support plate 222 , and a positioning bolt 226 is threadedly connected to the inside of the support block 225 . Positioning holes 227 are symmetrically opened on the top of the fixing plate 224 , and the positioning bolts 226 are adapted to be connected to the positioning holes 227 .

[0052] Example 1: Figures 1-6 As shown, when fixing the tool, if the tool is a circular carving tool or a triangular carving tool, the two bottom edges of the tool are placed on the two rubber pads 211, and the tool handle is placed in the placement slot on the top of the placement table 102. Then, the electric cylinder 202 can be started to drive the movable plate 203 to move downward. After the movable plate 203 moves downward, it can drive the positioning seat 207 to move downward. The positioning seat 207 moves downward so that the movable seat 208 abuts against the top of the tool. After that, the positioning seat 207 no longer moves, and the movable plate 203 continues to move to cause the connecting plate 205 to rotate, and The movable seat 208 can be pushed to slide on the support rod 209, so that the tool can be moved after being positioned by the positioning seat 207 and the movable seat 208. During the movement, the movable seat 208 drives the roller 217 between the mounting frame 216 to rotate. The roller 217 can push the movable plate 215 to move up under the action of the inclined plate 219, so that the movable rod 213 moves and the compression spring 214 is deformed, thereby making the rubber arc plate 2131 move up, so that the rubber arc plate 2131 can fit with the bottom of the tool, and then With the movement of the movable seat 208, the tool can be further positioned by the rubber arc plate 2131 to improve the positioning reliability. If the cross section of the tool is rectangular, the positioning bolt 226 can be removed and the support plate 222 can be moved, so that the adjustment plate 220 can be driven to move, and then the inclined plate 219 can be rotated, so that the movable frame 221 slides on the support plate 222, and the slope of the inclined plate 219 can be adjusted. Then, the positioning bolt 226 is inserted into another positioning hole 227 to position the support plate 222, thereby shortening the displacement of the movable rod 213 after the movable seat 208 moves, and it is convenient to adjust according to the type of tool. Then, as the movable seat 208 moves, the tool can be inserted into the tool handle and assembled through the interference fit between the tool and the tool handle. The positioning assembly 2 makes it possible to quickly and conveniently position the engraving tool, and after the engraving tool is positioned, it can be assembled with the tool handle, saving operation time and improving the continuity of assembly. In addition, the tool can be reliably positioned during the assembly process to avoid displacement of the tool during insertion into the tool handle, thereby improving convenience and practicality.

[0053] Two sets of sliding rods 228 are symmetrically slidably connected to the upper part of the movable seat 208, and a positioning bar 229 is fixedly installed on the side where the two sliding rods 228 are close to each other, and a telescopic spring 230 is sleeved on the outside of the two sliding rods 228 on one side of the positioning bar 229, and the two ends of the telescopic spring 230 are respectively fixedly connected to the movable seat 208 and the positioning bar 229, and a moving frame 232 is slidably connected to the outside of the two sliding rods 228, and an adaptable spring 231 is sleeved on the side of the moving frame 232, and the two ends of the adaptable spring 231 are respectively fixedly connected to the moving frame 232 and the sliding rod 228;

[0054] A steel wire rope 233 is fixedly installed at the bottom of the movable frame 232, and through grooves 234 are symmetrically opened in the middle of both sides of the movable seat 208, and the interior of the through grooves 234 is symmetrically connected to the guide wheels 235 for rotation. At the same time, the steel wire rope 233 is rotationally connected to the two guide wheels 235, and the ends of the two steel wire ropes 233 that are close to each other are fixedly connected to the movable plate 215.

[0055] Example 2: Figure 4-Figure 5 and Figure 7-Figure 8 As shown, the movable seat 208 causes the movable plate 215 to move during the movement. After the movable plate 215 moves, the wire rope 233 can be pulled to move. The wire rope 233 gradually straightens and can pull the movable frame 232 to move. The elastic potential energy of the telescopic spring 230 is less than the adaptive spring 231, so that after the movable frame 232 moves, the telescopic spring 230 is deformed, and then the two positioning bars 229 are in contact with the tool. If the movable frame 232 continues to move after the positioning bar 229 is in contact with the tool, the movable frame 232 can slide on the two sliding rods 228 and stretch the adaptive spring 231. The tool can be further positioned by the two positioning bars 229, further improving the positioning reliability, and the movement displacement of the two positioning bars 229 is consistent, so the tool can be calibrated to avoid the tool from being offset on the movable seat 208, avoid affecting the subsequent assembly effect, and improve practicality.

[0056] The fixing component 3 is arranged on the bottom of the workbench 1 and the top side of the placement table 102;

[0057] The fixing assembly 3 includes a U-shaped frame 301 fixedly mounted on the bottom of the movable seat 208, and a sliding plate 303 is fixedly mounted on one side of the U-shaped frame 301. A sliding groove 302 is provided on the top of the workbench 1 below the movable seat 208. The U-shaped frame 301 is slidably connected to the sliding groove 302, and the outer side of the sliding plate 303 is symmetrically slidably connected to a limit frame 304, and the limit frame 304 is fixedly connected to the workbench 1.

[0058] A push plate 305 is fixedly installed on one side of the top of the sliding plate 303, and a slope is set on one side of the push plate 305, and a sliding frame 306 is slidably connected to one side of the placement table 102 inside the workbench 1, and ball bearings 307 are symmetrically hinged on both sides of the sliding frame 306, and a vertical frame 308 is symmetrically installed on one side of the top of the placement table 102 close to the sliding frame 306, and a limit plate 309 is hinged between the two vertical frames 308, and torsion springs are set at the connection between the limit plate 309 and the two vertical frames 308.

[0059] Example 3: Figure 1-Figure 2 and Figure 9 As shown, the movable seat 208 can drive the U-shaped frame 301 to move during the movement, so that the sliding plate 303 can be driven to slide on the limit frame 304. After the sliding plate 303 moves, it can drive the push plate 305 to move. The push plate 305 can push the ball 307 to rotate through the slope, so that the sliding frame 306 can be lifted up. The sliding frame 306 can push the limit plate 309 to rotate between the vertical frames 308, so that the torsion spring is deformed, so that the limit plate 309 can cover the top of the knife handle, so that the knife handle is close to the placement groove, so that the knife handle can be fixed, avoiding the knife handle from shifting during the assembly process, and improving the accuracy of assembly.

[0060] Working principle: When using this convenient positioning tool for carving knife production, first, according to Figures 1-9As shown, when fixing the tool, if the tool is a circular carving tool or a triangular carving tool, the two bottom edges of the tool are placed on the two rubber pads 211, and the tool handle is placed in the placement slot on the top of the placement table 102. Then the electric cylinder 202 can be started to drive the movable plate 203 to move downward. After the movable plate 203 moves downward, it can drive the positioning seat 207 to move downward. The positioning seat 207 moves downward so that the movable seat 208 abuts against the top of the tool. Then the positioning seat 207 no longer moves, and the movable plate 203 continues to move to make the connecting plate 205 rotate, and can push the movable seat 208 to slide on the support rod 209, so that the tool can be moved after being positioned by the positioning seat 207 and the movable seat 208. During the movement, the movable seat 208 drives the roller 217 between the mounting frame 216 to rotate, and the roller 217 can push the movable plate 215 to move up under the action of the inclined plate 219, so that the movable rod 213 moves and the compression spring The cam 214 is deformed, and the rubber arc plate 2131 is moved upward, so that the rubber arc plate 2131 can fit with the bottom of the tool. Then, as the movable seat 208 moves, the tool can be further positioned by the rubber arc plate 2131, thereby improving the positioning reliability. If the cross section of the tool is rectangular, the positioning bolt 226 can be removed and the support plate 222 can be moved, so that the adjustment plate 220 can be driven to move, and the inclined plate 219 can be rotated, so that the movable frame 221 slides on the support plate 222, and the slope of the inclined plate 219 can be adjusted. Then, the positioning bolt 226 is inserted into another positioning hole 227 to position the support plate 222, thereby shortening the displacement of the movable rod 213 after the movable seat 208 moves, which is convenient for adjustment according to the type of tool. Then, as the movable seat 208 moves, the tool can be inserted into the tool handle, and the tool and the tool handle are assembled through the interference fit.

[0061] The movable seat 208 moves the movable plate 215 during the movement process. After the movable plate 215 moves, the steel wire rope 233 can be pulled to move. The steel wire rope 233 gradually straightens and can pull the movable frame 232 to move. The elastic potential energy of the telescopic spring 230 is less than the adaptive spring 231, so that after the movable frame 232 moves, the telescopic spring 230 is deformed, thereby causing the two positioning bars 229 to contact the tool. If the movable frame 232 continues to move after the positioning bars 229 contact the tool, the movable frame 232 can slide on the two sliding rods 228 and stretch the adaptive spring 231. The tool can be further positioned through the two positioning bars 229, further improving the positioning reliability, and the two positioning bars 229 The moving displacement is consistent, and the tool can be calibrated to avoid the tool being offset on the movable seat 208. The movable seat 208 can drive the U-shaped frame 301 to move during the movement, so that the sliding plate 303 can be driven to slide on the limit frame 304. After the sliding plate 303 moves, it can drive the push plate 305 to move. The push plate 305 can push the ball bearing 307 to rotate through the slope, so that the sliding frame 306 can be lifted up, and the sliding frame 306 can push the limit plate 309 to rotate between the vertical frames 308, so that the torsion spring is deformed, so that the limit plate 309 can cover the top of the knife handle, so that the knife handle is close to the placement slot, so that the knife handle can be fixed, avoiding the knife handle from shifting during the assembly process, and improving the accuracy of assembly.
