Technical Field
[0001] This utility model relates to the field of tooling fixtures, and in particular to a modular adjustable tooling fixture for gradient tempering of martensitic steel. Background Technology
[0002] The microstructure of martensitic steel is almost entirely martensitic. It is mainly produced by rapidly quenching austenitic structure at high temperature to transform it into lath martensite, and then tempering it at low temperature to obtain tempered martensite. Tempering is generally not used alone. It is performed after the quenching treatment of the parts. The main purpose of tempering is to eliminate quenching stress and obtain the required microstructure.
[0003] In existing technologies, when processing martensitic steel workpieces, low-temperature tempering is required. Before tempering, the workpieces need to be placed on a fixture in the tempering furnace. Existing tooling fixtures fix the workpieces by mounting fixtures on a simple bracket. After each tempering, when the next batch of workpieces needs to be tempered, the workpieces need to be repeatedly disassembled and assembled, which is cumbersome and affects the efficiency of tempering. To address this issue, a modular adjustable tooling fixture for gradient tempering of martensitic steel is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a modular adjustable tooling fixture for gradient tempering of martensitic steel, which aims to solve the problem in the prior art that "when tempering the next batch of workpieces after each tempering is completed, it is necessary to repeatedly disassemble and assemble the workpieces one by one, which is cumbersome and affects the efficiency of tempering processing".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular adjustable tooling fixture for gradient tempering of martensitic steel, comprising a support base, a mounting plate fixedly connected to the top of the support base, an installation adjustment mechanism provided on the upper surface of the mounting plate, the installation adjustment mechanism comprising a module connection assembly, the module connection assembly comprising a limiting plate and a connecting rod, the limiting plate fixedly connected to the upper surface of the mounting plate, the connecting rod slidably disposed on the inner wall of the mounting plate, a splicing groove provided on the inner wall of the limiting plate, a splicing block detachably connected to the inner wall of the splicing groove, a connecting block fixedly connected to the outer wall of the splicing block, a limiting block fixedly connected to the outer wall of the connecting rod, and a pressure plate fixedly connected to the top of the connecting rod.
[0006] As a further description of the above technical solution: The installation and adjustment mechanism further includes an adjustment component, which includes a connecting plate and a fixing rod. The connecting plate is fixedly connected to the outer wall of the splicing block, and an extension rod is slidably connected to the inner wall of the connecting plate. The fixing rod is fixedly connected to the outer wall of the pressure plate, and a locking block is slidably connected to the inner wall of the fixing rod. Friction textures are provided on the upper surface of the extension rod and the inner wall of the locking block.
[0007] As a further description of the above technical solution: The splicing slots are provided in multiple sets, and the multiple sets of splicing slots are arranged in a rotating array with the center line of the limiting plate as the rotation axis.
[0008] As a further description of the above technical solution: The end of the extension rod furthest from the splicing block is fixedly connected to a clamping component.
[0009] As a further description of the above technical solution: A base plate is fixedly connected to the bottom of the support base, and a take-out block is fixedly connected to the outer wall of the support base.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a modular adjustable tooling fixture for gradient tempering of martensitic steel, comprising a support base 1 for mounting and supporting other components. A mounting plate 2 for mounting and placing a modular connecting assembly 3 is fixedly connected to the top of the support base 1. An adjustment mechanism is provided on the upper surface of the mounting plate 2, including a modular connecting assembly 3 for quickly changing different clamping parts 5. The modular connecting assembly 3 includes a limiting plate 31 and a connecting rod 32. The limiting plate 31 is used to mount and connect splicing blocks 34, and is fixedly connected to the upper surface of the mounting plate 2, supported and fixed by the mounting plate 2. The connecting rod 32 is slidably disposed on the inner wall of the mounting plate 2, and is used to drive the pressure... The plate 37 is kept in a pressed and raised state. The inner wall of the limiting plate 31 is provided with a splicing groove 33 for installing and fixing the splicing block 34. The inner wall of the splicing groove 33 is detachably connected to the splicing block 34 for connecting the connecting plate 41 so that it can be quickly installed. The outer wall of the splicing block 34 is fixedly connected to the connecting block 35. The connecting block 35 will be installed together with the splicing block 34 inside the splicing groove 33 and restrict the shaking of the splicing block 34. The outer wall of the connecting rod 32 is fixedly connected to the limiting block 36 for restricting the sliding of the connecting rod 32, so as to prevent the pressure plate 37 from sliding up and down when it is pressed on the limiting plate 31. The top of the connecting rod 32 is fixedly connected to the pressure plate 37 for pressing down the splicing block 34, so as to prevent the splicing block 34 from detaching from the splicing groove 33.
[0019] Reference Figure 2 , Figure 3 and Figure 4 The installation and adjustment mechanism also includes an adjustment assembly 4 for adjusting the distance of the clamping member 5. The adjustment assembly 4 includes a connecting plate 41 and a fixing rod 42. The connecting plate 41 is used to install the support extension rod 43. The connecting plate 41 is fixedly connected to the outer wall of the splicing block 34 and is disassembled and replaced along with the splicing block 34. The extension rod 43 is slidably connected to the inner wall of the connecting plate 41. The extension rod 43 is used to adjust the distance from the clamping member 5 to the support base 1 to accommodate different sizes of steel. The fixing rod 42 is fixedly connected to the outer wall of the pressure plate 37 and is used to drive the locking block 44 to lock the extension rod 43. The inner wall of the fixing rod 42 is... The wall sliding connection has a locking block 44 for limiting the sliding of the extension rod 43. The upper surface of the extension rod 43 and the inner wall of the locking block 44 are both provided with friction textures 45 to prevent the extension rod 43 from sliding on the inner wall of the connecting plate 41. The locking block 44 is C-shaped to limit the sliding of the extension rod 43 and prevent the extended extension rod 43 from shaking. The friction textures 45 are arc-shaped with the center line of the support base 1 as the axis. Since the fixed rod 42 will rotate with the pressure plate 37, the arc-shaped friction textures 45 will be able to stably fit and rub against each other when the locking block 44 rotates and locks.
[0020] Reference Figure 2 and Figure 4Multiple sets of splicing slots 33 are provided, and the multiple sets of splicing slots 33 are arranged in a rotating array with the center line of the limiting plate 31 as the rotation axis. Different shapes of steel can be installed by clamping component 5. With the help of the adjustment component 4, the steel can be prevented from colliding with each other to avoid affecting the tempering effect. The end of the extension rod 43 away from the splicing block 34 is fixedly connected to the clamping component 5. Different clamping components 5 are selected according to different steels during use. The bottom of the support base 1 is fixedly connected to the base plate 6 for stabilizing device. The outer wall of the support base 1 is fixedly connected to the removal block 7. The user can fix or remove the device by removing the removal block 7. The shape of the mounting plate 2 and the limiting plate 31 is set as polygonal, which can make the installed steel evenly distributed. The shape of the splicing block 34 is set as triangular. With the help of the polygonal limiting plate 31, the splicing block 34 can be stably fixed. The top of the pressure plate 37 is fixedly connected to the handle 8, which makes it convenient to rotate and lift the pressure plate 37 when installing the splicing block 34.
[0021] Working principle: In use, the operator first pulls the handle 8 upwards, causing the pressure plate 37 and its fixedly connected connecting rod 32 to rise. The limiting block 36 on the connecting rod 32 moves upwards, releasing the restriction on the sliding of the connecting rod 32, and causing the pressure plate 37 to move away from the limiting plate 31. At this time, the selected clamping part 5, which matches the shape of the martensitic steel to be processed, and its connected extension rod 43, connecting plate 41, splicing block 34, and connecting block 35 can be used as a whole module. Align the splicing block 34 and insert it into the selected splicing groove 33 on the limiting plate 31. The connecting block 35 then embeds into the groove, playing a preliminary positioning and anti-shaking role. Release the handle 8, and under the action of gravity or auxiliary pressure, the pressure plate 37 falls back to its original position, pressing down again on the top of the splicing block 34. The downward pressure of the pressure plate 37 is transmitted through the splicing block 34 to the bottom of the splicing groove 33, firmly pressing and fixing the entire module to the limiting plate 31, preventing it from detaching from the splicing groove 33. At the same time, the limiting block 36 on the connecting rod 32 moves down, and the handle 8 is rotated so that the limiting block 36 abuts against the corresponding structure of the support base, locking the position of the connecting rod 32 and preventing it from accidentally sliding and lifting up in the working state. Before turning the handle 8, the operator pulls the extension rod 43 outward to adjust the distance between the clamping piece 5 and the support base 1. The rotating handle 8 will drive the fixed rod 42 and the locking block 44 to move. Its C-shaped structure clamps the extension rod 43. The inner wall of the locking block 44 meshes with the arc-shaped friction texture 45 set on the upper surface of the extension rod 43 with the center line of the support base 1 as the axis. At this time, the locking block 44 is locked. These mutually fitting arc-shaped friction textures 45 generate strong friction force, which effectively prevents the extension rod 43 from sliding on the inner wall of the connecting plate 41, ensuring the stability of the clamping position. At the same time, the design of the C-shaped locking block 44 not only restricts the axial sliding of the extension rod 43, but also provides lateral support, effectively avoiding the shaking of the extended extension rod 43 during the operation. The martensitic steel workpiece to be processed is placed on the corresponding clamping piece 5 and fixed. Because the limiting plate 31 has multiple sets of splicing slots 33 arranged in an array with its center line as the axis of rotation, the operator can selectively install one or more clamping modules in the splicing slots 33 at different angles and radial positions, according to the shape, size, and tempering process requirements of the workpiece, to avoid contact between workpieces and ensure uniform heat conduction and atmosphere flow. With the independent distance adjustment function of each module, workpieces can be flexibly arranged, ensuring that they maintain appropriate spacing, do not contact each other, and are evenly distributed in the space around the fixture. The polygonal design of the mounting plate 2 and the limiting plate 31 further promotes the uniform distribution of workpieces. The fixture as a whole, along with the clamped workpiece, is sent into the tempering furnace for gradient tempering. After tempering, the fixture is removed from the furnace and can be easily moved by removing block 7. After disassembling the workpiece, if it is necessary to change the type or configuration of the clamping component 5, simply lift the pressure plate 37 according to step 1 to remove the entire clamping module from the splicing slot 33 and replace it with another type of module, improving the overall tempering processing speed.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
