Description

Technical Field

[0001] The present invention relates to the technical field of mortise and tenon knives, and in particular to a production process and production equipment of a three-edged T-shaped mortise and tenon knife. Background Art

[0002] Woodworking tools are tools that use cutting methods to process wood into the required shape and size. Woodworking tools are of two types: hand-used and machine-used. Machine-used woodworking tools are used in batch and mass production.

[0003] In the prior art, most processing equipment for producing multi-blade mortise and tenon knives requires that workpieces be installed one by one for processing, resulting in the need for operators to operate continuously during processing, which greatly increases the labor force and slows down production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a three-edged T-shaped mortise and tenon knife production process and production equipment to solve the above problems.

[0005] In view of this, the present invention provides a three-edged T-shaped mortise and tenon knife production process, comprising the following steps:

[0006] S1: First, the cylindrical rod material is processed into a tool holder with a limit sleeve through a lathe, and a threaded hole is drilled at the top of the tool holder;

[0007] S2: Then, a hole is drilled in the middle of the disc material to fit on the tool handle, and then several hollow disc materials are placed on the material placement device;

[0008] S3: The loading device sequentially transfers the hollow disc material to the blade processing device and retrieves the processed hollow disc with one blade. The blade processing device successively processes three blades on the outer wall of the hollow disc to complete the three-blade cutter head;

[0009] S4: Install the cutter body on the three-edged cutter head;

[0010] S5: First, install a three-blade cutter head on the tool handle and attach it to the limit sleeve. Then install a gasket on the top of the first three-blade cutter head, install a connecting sleeve on the top of the gasket, install another gasket on the top of the gasket, install another three-blade cutter head, and finally fix the entire limit with fasteners.

[0011] By adopting the above technical solution, through the setting of S1, the tool holder and threaded hole with the limit sleeve are first processed, so that the cutter head can be fixed when the limit part is installed. Through the setting of S2, multiple hollow discs can be placed, so that several hollow discs can be processed successively. Through the setting of S3, the blade processing device can first process one blade of the hollow disc in turn, and then the one-blade hollow disc is retrieved through the material placement device for rotation to process the next blade until all three blades are processed. At this time, the processing of several three-blade cutter heads is completed, which greatly improves the processing efficiency. Through the setting of S4, the cutting body can be installed on the three-blade cutter head. Through the setting of S5, the overall installation and disassembly can be greatly improved, and when a cutter head or cutter body is damaged, only a separate one needs to be replaced, which greatly saves the cost of overall replacement.

[0012] In the above technical solution, the further material placing device includes:

[0013] Workbench;

[0014] a first rotating motor having a fixed end disposed on the workbench and an output end extending away from the workbench;

[0015] A rotating disk is provided on the output end of the first rotating motor, and the rotating disk is provided with a plurality of mounting holes arranged in an annular array around the center of the rotating disk;

[0016] and a plurality of rotating clamping mechanisms, which are arranged in the mounting holes, with the clamping ends of the rotating clamping mechanisms facing downwards of the rotating disk;

[0017] Among them, several of the rotating clamping mechanisms are used to clamp hollow disc materials or processed three-edged cutter heads.

[0018] In this technical solution, through the setting of the first rotating motor, the rotating disk can be rotated, so that several rotating clamping mechanisms can be changed in position, so that the hollow disc materials can be placed on the blade processing device one by one, and the processed materials can be clamped after the blade processing device completes the processing.

[0019] In the above technical solution, the rotating clamping mechanism further includes:

[0020] A connecting column, one end of which is located in the mounting hole and the other end is located above the rotating disk, and a limiting ring is provided on the outer wall of the connecting column and rotates on the inner wall of the mounting hole;

[0021] The external gear is arranged on the outer side wall of the connecting column and is located above the mounting hole;

[0022] A second rotating motor is provided on the rotating disk, and an output end of the second rotating motor is provided with a transmission tooth meshing with the external gear;

[0023] A first hydraulic cylinder, with a fixed end disposed at the top of the connecting column and an output end penetrating the connecting column and located at the bottom end of the rotating disk;

[0024] A first clamping structure is provided on the output end of the first hydraulic cylinder;

[0025] The first clamping structure is used to clamp the hollow disc material or the processed three-edged cutter head.

[0026] In this technical solution, through the setting of the second rotating motor, the transmission teeth can drive the external gear to rotate, thereby causing the connecting column to rotate. Through the setting of the limit ring, the connecting column can be prevented from moving up and down and can only rotate. Through the rotation of the connecting column, the first hydraulic cylinder is rotated, thereby causing the first clamping structure to rotate, causing the hollow disc material to rotate, thereby obtaining the next blade processing. Through the setting of the first hydraulic cylinder, the first clamping structure can rise and fall, thereby transferring the hollow disc material to the blade processing device.

[0027] In the above technical solution, the first clamping structure further includes:

[0028] A fixed block is provided on the output end of the first hydraulic cylinder, and a movable groove is provided on an end of the fixed block away from the output end of the first hydraulic cylinder;

[0029] Two L-shaped rods, one end of which is respectively inserted into and slides in the inner walls of both sides of the movable groove, and the other end of which extends toward the opening of the movable groove;

[0030] Two driving blocks are respectively arranged at one end of the L-shaped rod facing the opening of the movable slot;

[0031] Two second hydraulic cylinders, with fixed ends respectively arranged on both sides of the fixed block, and output ends both passing through the fixed block and connected to the ends of the L-shaped rod;

[0032] and a clamping assembly, disposed at an end of the driving block away from the end connected to the first hydraulic cylinder;

[0033] The driving block drives the clamping assembly to clamp the hollow disc material or the processed three-edged cutter head.

[0034] In this technical solution, by setting up the second hydraulic cylinder, the L-shaped rod can be pushed out or retracted, thereby causing the driving block to move out or retract, so that the driving block drives the clamping assembly to clamp or release.

[0035] In the above technical solution, the clamping assembly further includes:

[0036] A mounting block is provided on a side of the driving block facing away from the first hydraulic cylinder, wherein a driving cavity is provided in the mounting block; and two through holes are provided on a side of the driving cavity facing the movable groove and opposite to each other and connected to the movable groove;

[0037] Two arc-shaped blocks are rotatably connected to the inner walls of the two through holes respectively;

[0038] Two push plates slide on both sides of the driving cavity and are located on both sides of the two arc blocks;

[0039] Two driving rods are respectively arranged on one side of the arc block facing the driving cavity;

[0040] Two connecting rods, one end of which is respectively arranged on the side of the two push plates facing away from each other, and the other end of which passes through the mounting block;

[0041] and two arc-shaped pressing blocks, respectively arranged at ends of the two connecting rods facing away from each other;

[0042] Wherein, elastic parts for rebounding the push plate are provided on both side walls of the driving cavity, and the driving block is used to drive the arc block to rotate upward, so that the driving rod pushes the push plate to move, thereby pushing out the connecting rod.

[0043] In the present technical solution, by setting the through hole, the arc block can be rotated into the movable groove and the driving cavity through the driving block. By setting the driving rod, when the arc block is rotated into the driving cavity, the driving rod can be pushed against the push plate to advance, so that the connecting rod extends to the outside of the mounting block, thereby obtaining the arc pressure block to clamp the inner wall of the hollow disc material. By setting the elastic part, when the driving rod does not conflict with the push plate, the push plate is pushed back by the elastic part, thereby releasing the clamping of the arc pressure block.

[0044] In the above technical solution, the blade processing device further includes a slide rail mechanism arranged on the workbench, a second clamping structure with the same structure as the first clamping structure, and a cutting structure arranged on the workbench. The fixed end of the second clamping structure is arranged on the slide rail mechanism, and the clamping end faces the rotating disk. The slide rail mechanism causes the hollow disc material to slide along the sliding direction of the slide rail mechanism through the second clamping knot, so that the cutting structure cuts the outer wall of the hollow disc. The material placement device places the hollow disc material on the second clamping structure at the initial position of the slide rail mechanism, and clamps the material with the processed blade away at the end position of the slide rail mechanism.

[0045] In the technical solution, the first clamping structure clamping end is downward and the second clamping structure clamping end is upward, so that when the first clamping structure and the second clamping structure are in the corresponding position, the first hydraulic cylinder pushes the first clamping structure to descend, so that the second clamping structure clamps the hollow disc material, then the first clamping structure is loosened and the first hydraulic cylinder is pulled back, at this time the hollow disc material transmission is completed, when the second clamping structure moves to the end of the slide rail mechanism and the cutting of the hollow disc material is completed, the placing device rotates the just loosened first clamping structure to clamp the cut hollow disc material, then the slide rail mechanism moves back to the initial position, and the cutting structure is the existing cutting structure.

[0046] In the above technical solution, the slide rail mechanism further comprises:

[0047] The fixed seat is provided on the workbench, and a work groove is arranged on one side of the fixed seat;

[0048] The rotating block is arranged on the workbench and located on one side of the work groove opening;

[0049] The two connecting plates are oppositely arranged on the two sides of the inner wall of the work groove, and one end of each connecting plate is fixedly connected with the work groove, and the other end is rotatably connected with the rotating block;

[0050] The two fixed plates are arranged at intervals between the two connecting plates, and the two fixed plates are fixedly connected to one side of the rotating block facing the work groove;

[0051] The slide rail is arranged at the bottom of the work groove, and extends towards the rotating block, and a sliding groove is arranged on the slide rail;

[0052] The placing block is arranged on one side of the rotating block facing the work groove, and the placing block is located on the side of the rotating block away from the fixed plate;

[0053] The first rotating rod is rotatably connected between the two fixed plates;

[0054] The second rotating rod is rotatably connected to one end of the first rotating rod away from the two fixed plates;

[0055] The swing rod is rotatably connected to the placing block through an eccentric shaft;

[0056] And the stud is rotatably connected with the second rotating rod and the swing rod below the slide rail, and the stud slides in the guide groove;

[0057] The top end of the fixed seat is provided with a sliding hole corresponding to the sliding groove, the top end of the stud is provided with a connecting structure connected with the second clamping structure through the sliding hole, and the workbench is provided with two driving structures for driving the rotating block to rotate and return.

[0058] In this technical solution, through the setting of two connecting plates, the rotating block can rotate on the fixed seat. When the rotating block rotates, the placing block follows the rotation. Due to the setting of the rocker arm and the eccentric shaft, the pin slides in the slide groove, and at the same time, the first rotating rod and the second rotating rod rotate to corresponding positions. Since the first rotating rod, the second rotating rod, the rocker arm and the rotating block form a four-bar linkage, the rotational force can be amplified by the four-bar linkage, and the sliding of the pin is made more stable. Through the cooperation of the slide rail and the slide groove, the pin can slide along the slide groove. The above-mentioned slide groove can be set according to the needs of the operator, so as to change the curvature processing of the hollow disc blade to achieve the required curvature.

[0059] In the above technical solution, the further connecting structure includes a driving rod and four limit plates, one end of the driving rod is connected to the cancellation, and the other end is connected to the second clamping structure. The four limit plates are arranged on the side wall of the driving rod at intervals and relative to each other, and two limit plates are located in the working groove, and the other two limit plates are located at the top of the fixed seat.

[0060] In this technical solution, by setting the driving rod, the second clamping structure can follow the pin to move in the sliding groove, and by setting the four limit plates, the driving rod can be restricted to reduce shaking.

[0061] In the above technical solution, the driving structure further includes:

[0062] a third rotating motor, disposed on the workbench;

[0063] A driving block is provided on the output end of the third rotating motor, and an annular groove is provided on the outer side wall of the driving block;

[0064] A pull rope, one end of which is arranged at the bottom of the limiting ring groove and the other end is connected to the rotating block;

[0065] When the third rotating motor rotates, the driving block winds or releases the pull rope, thereby pulling the rotating block to rotate or pull back the rotating block.

[0066] In this technical solution, when the third motor rotates, it drives the block to rotate, so that the pull rope is wrapped around the ring groove or loosened from the ring groove, and finally a pulling force is exerted on the rotating block, causing the rotating block to rotate.

[0067] The beneficial effects of the present invention are:

[0068] 1. Through the setting of the material placement device, several hollow disc materials can be processed successively, and multiple surfaces can be processed and cut one by one;

[0069] 2. Through the setting of the blade processing device, the desired arc edge can be cut out of the hollow cylindrical material. BRIEF DESCRIPTION OF THE DRAWINGS

The slide rail 30 mechanism causes the hollow disc material to slide along the sliding direction of the slide rail 30 mechanism through the second clamping knot, so that the cutting structure 24 cuts the outer wall of the hollow disc. The material placing device places the hollow disc material on the second clamping structure at the initial position of the slide rail 30 mechanism, and clamps away the material with the processed blade at the end position of the slide rail 30 mechanism.

[0132] By arranging the clamping end of the first clamping structure downward and the clamping end of the second clamping structure upward, when the first clamping structure and the second clamping structure are in corresponding positions, the first hydraulic cylinder 8 pushes the first clamping structure to descend, so that the second clamping structure clamps the hollow disc material, and then the first clamping structure is released and the first hydraulic cylinder 8 pulls back, at this time the transfer of the hollow disc material is completed, and when the second clamping structure follows the slide rail 30 mechanism to move to the end and the processing of one edge of the hollow disc material is completed, the material placing device rotates the first clamping structure that has just been released to clamp the processed one-edge hollow disc material, and then the slide rail 30 mechanism moves back to the initial position, and the above-mentioned cutting structure 24 is the existing cutting structure 24.
