Abstract
Description
Technical Field
[0001] This invention relates to the field of cutting tool manufacturing technology, and in particular to a blade welding device for a T-type finger joint knife. Background Technology
[0002] T-type (trapezoidal) finger joint cutters can be divided into two types according to their structure: single-piece cutters and integral cutters. A single-piece cutter is a thin cutter, its thickness equal to the pitch of the finger joint. Multiple cutters are stacked and secured together with a sleeve and nut, or simply with a nut. A T-type finger joint cutter typically consists of two parts: a trapezoidal insert and a cutter body. The cutter body usually has two notches, with the insert welded to one side of the notch. However, currently, manual welding is generally used. Manual welding has several drawbacks: for example, it is difficult to control the welding temperature and time. Too low a temperature or too short a time may result in a weak weld; too high a temperature or too long a time may cause excessive tool deformation. Both of these situations seriously affect the quality of the tool, and also result in low production efficiency and high labor intensity. Summary of the Invention

[0053] Example 1:
[0054] like Figures 1 to 3 As shown, this invention discloses a blade welding device for a T-type finger joint knife, including a worktable 1, and further comprising:
[0055] Support base 2 is fixedly connected to one side of the upper end of workbench 1;
[0056] The blade support device is fixedly connected above the support base 2 to fix the blade;
[0057] A high-frequency welding machine is fixedly installed on one side of the upper end of workbench 1;
[0058] One end of the high-frequency welding machine is equipped with an induction coil that extends towards the blade support device.
[0059] By adopting the above technical solution, and using a tool body support device in conjunction with a high-frequency welding machine, the blade can be precisely and efficiently welded onto the tool body, reducing manual labor intensity and improving tool quality.
[0060] Example 2:
[0061] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0062] Furthermore, the blade support device includes:
[0063] The first fixed seat 3 is fixedly connected to the upper end of the support seat 2;
[0064] The second fixing seat 4 is fixedly connected to the upper end of the first fixing seat 3, and the second fixing seat 4 is in the shape of a "U".
[0065] Lead screw 5 is fixedly connected to both sides inside the second fixed seat 4;
[0066] The movable seat 6 is threadedly connected to the lead screw 5;
[0067] The clamping device is fixedly connected to the upper end of the movable base 6;
[0068] The lower end of the movable seat 6 is slidably connected to the bottom of the second fixed seat 4.
[0069] By adopting the above technical solution, the relative position of the moving seat and the induction coil on the high-frequency welding machine can be stably adjusted through the screw and moving seat, and it occupies little space and is easy to disassemble and assemble.
[0070] Example 3:
[0071] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0072] Furthermore, the movable seat 6 includes:
[0073] A through hole is made on the movable seat 6, with both ends of the through hole penetrating the left and right sides of the movable seat 6 respectively;
[0074] The first stepper motor 7 is fixedly connected to the front side of the movable base 6;
[0075] The cylinder 8 is rotatably connected to the through hole. The inner side of the cylinder 8 is provided with an internal thread that cooperates with the lead screw 5. The two ends of the cylinder 8 protrude from the left and right sides of the movable seat 6 respectively.
[0076] Driven gear 9 is fixedly connected to one end of cylinder 8;
[0077] Among them, a first driving gear for meshing and transmission with the driven gear 9 is fixedly installed on the output shaft of the first stepper motor 7, and a limit ring sleeve 10 is fixedly installed on the end of the cylinder 8 away from the driven gear 9.
[0078] By adopting the above technical solution, when the first stepper motor starts, the first driving gear drives the driven gear to rotate, thereby driving the cylinder to rotate. Since the cylinder and the lead screw are threaded, the cylinder can move on the lead screw, thereby driving the moving seat to move and drive the cutter body and blade installed on the clamping device to move towards the induction coil. At the same time, the cylinder, driven gear and the first stepper motor are easy to assemble and disassemble, and occupy little space.
[0079] Example 4:
[0080] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0081] Furthermore, the clamping device includes:
[0082] Rotary seat 11 is rotatably connected to the upper end of movable seat 6;
[0083] Loading platform 12 is located above rotating seat 11;
[0084] Two hydraulic rods 13 are provided, and the two hydraulic rods 13 are fixedly installed on the upper two sides of the rotating seat 11. The end of the hydraulic rod 13 facing away from the rotating seat 11 is fixedly installed on the lower end of the loading platform 12.
[0085] By adopting the above technical solution, the hydraulic rod can provide support and adjust the real-time height of the loading platform to facilitate the alignment of the blade and the induction coil.
[0086] Example 5:
[0087] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0088] Furthermore, the clamping device also includes:
[0089] The second stepper motor 14 is fixedly installed on one side of the lower end of the loading platform 12, and the length direction of the output shaft of the second stepper motor 14 is parallel to the loading platform 12.
[0090] Vertical plate 16 is fixedly installed on one side of the lower end of loading platform 12;
[0091] The first skateboard 17 is L-shaped and includes a first horizontal part and a first vertical part that are integrally formed.
[0092] The second skateboard 18 is located below the first skateboard 17 and is L-shaped, including an integrally formed second horizontal part and a second vertical part;
[0093] The second drive gear 15 is located between the first transverse portion and the second transverse portion and is keyed to the output shaft of the second stepper motor 14;
[0094] The first horizontal section and the second horizontal section are slidably connected to the side of the vertical plate 16 facing the second stepper motor 14. The lower end of the first horizontal section and the upper end of the second horizontal section are both fixedly installed with racks for meshing with the second drive gear 15. The horizontal height of the upper end surfaces of the first vertical section and the second vertical section is higher than the horizontal height of the upper end surface of the loading table 12. The upper ends of the first vertical section and the second vertical section are respectively installed with a first arc-shaped pressure block and a second arc-shaped pressure block for pressing the two sides of the blade body respectively.
[0095] By adopting the above technical solution, after the blade body is placed, the second stepper motor is started. When the second stepper motor rotates counterclockwise, the second drive gear drives the rack to move the first and second slide plates synchronously and move closer to each other. This causes the two arc-shaped pressure blocks connected to the first and second slide plates to move closer to each other and press the blade body. Similarly, when the second stepper motor rotates clockwise, the two arc-shaped pressure blocks move away from each other synchronously. At this time, the blade body can be removed.
[0096] Example 6:
[0097] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0098] Furthermore, the clamping device also includes:
[0099] The fixed column 19 has a "convex" cross-section and is fixedly installed at the middle of the upper end of the loading table 12 for the insertion of the blade body;
[0100] Two limit plates 20 are provided, and the two limit plates 20 are fixedly installed on both sides of the upper end of the loading platform 12;
[0101] The elastic element 21 is detachably and fixedly installed on one side wall of the limiting plate 20;
[0102] The blade support plate is L-shaped and is fixedly installed on the end of the elastic element 21 that is away from the limiting plate 20;
[0103] The width of the blade support plate is smaller than the width of the blade.
[0104] By adopting the above technical solution, the fixed column is used to insert the blade body, and the limiting plate can cooperate with the notch of the blade body to achieve the positioning of the blade body. The installation position of the limiting plate can be adjusted according to the actual size and shape of the notch on the blade body. After the blade body is fixed, the blade can be placed on the blade support plate. Due to the elastic force of the elastic element, the blade can be pressed on one side of the notch of the blade body. The width of the blade support plate is smaller than the width of the blade, so that when the blade body moves towards the induction coil, the blade support plate is not easy to collide and interfere with the induction coil.

[0106] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0107] Furthermore, the elastic element 21 is a "Z"-shaped spring sheet, and the two ends of the spring sheet are fixedly connected to the limiting plate 20 and the blade bearing plate respectively by screws.
[0108] By adopting the above technical solution, the spring clips are easy to disassemble and replace, and the effect is good.
[0109] Example 8:
[0110] This embodiment provides a blade welding device for a T-type finger joint knife, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0111] Furthermore, the blade support device also includes:

[0114] The rotating base 11 is disc-shaped, and the output shaft of the third stepper motor 22 is keyed with a third drive gear 23 that meshes with the teeth.
[0115] By adopting the above technical solution, after starting the third stepper motor, the third active gear can drive the rotating disk to drive the transfer table to rotate for installing the blade or to make the contact part between the blade and the blade body approach the induction coil at different angles for high-frequency welding.
