Description

Technical Field

[0001] This invention relates to the field of component clamping technology, specifically to a detachable multi-purpose component clamping assembly. Background Technology

[0002] Fixtures are used to fix and position workpieces, ensuring they remain stable during machining, measurement, or assembly. However, existing fixtures still have some problems in use, as follows: In daily use, traditional fixed fixtures are usually designed for specific workpieces or single processes. Their rigid structure and narrow scope of application mean that when dealing with different sizes, shapes, and especially irregularly shaped parts, multiple sets of special fixtures are often required, resulting in high costs, cumbersome replacement, and inconvenient storage. Therefore, there is a need for a modular fixture system that is flexible, highly expandable, and easy to operate. This system can adapt to the clamping needs of diverse workpieces through the rapid combination and disassembly of standardized connectors, significantly improving the applicability and overall work efficiency of the fixture while ensuring rigidity and stability. Summary of the Invention

[0003] This invention provides a detachable multi-purpose component clamp assembly, which has the advantages of flexible structure, strong expandability and easy operation, and solves the problems mentioned in the background art.

[0004] This invention provides the following technical solution: a detachable multi-purpose parts clamp assembly, comprising: A workbench, with a fixed plate fixedly connected to its top, also includes a quick-release assembly located at the connection between the fixed plate and the workbench. The quick-release assembly includes a pin, a support shaft, a locking block, a first spring, and a locking ring. The main body of the pin passes through a corresponding through hole on the component to be connected. Both ends of the support shaft are fixed inside the top of the pin. The locking block has a through hole in its middle and is rotatably fitted onto the support shaft. Both ends of the locking block are accommodated in a sliding groove at the top of the pin and can slide along it. The bottom of the locking block has a slope or arc surface. The first spring is located inside the locking block or against its side, providing an elastic force that causes the two ends of the locking block to tend to open outwards. The locking ring is fitted onto the pin and located above the component to be locked. When the locking ring slides downwards along the pin, its inner edge or lower end face presses against the bottom surface of the locking block, forcing the locking block to overcome the elastic force of the first spring and retract inwards, thereby locking the pin and the connected component. A support plate, the bottom of which is detachably mounted above the fixed plate via at least one set of first dovetail groove connecting structures; two positioning plates, respectively detachably mounted on opposite sides of the support plate via second dovetail groove connecting structures; each positioning plate having a guide groove vertically formed inside; multiple quick-release assemblies, including at least a first quick-release assembly for locking the fixed plate onto the worktable, and multiple second quick-release assemblies for connecting moving parts; and a clamping drive assembly, which is detachably mounted to the support plate via at least one set of second quick-release assemblies. On the side, there are two symmetrically arranged clamping arm units, each of which includes an up-pass rod and a down-pass rod. One end of the up-pass rod and the down-pass rod are hinged to the clamping drive assembly via the second quick-release group. The middle part of the up-pass rod and the down-pass rod is movably connected to the guide groove on the positioning plate via a sliding pin. The other end of the up-pass rod and the down-pass rod is used to install the working part that performs the clamping action. The clamping drive assembly is used to drive the up-pass rod and the down-pass rod of the two clamping arm units to move synchronously towards or away from each other, so as to achieve clamping and releasing of the parts.

[0005] In a preferred embodiment, the clamping drive assembly includes a cylinder, a fixed shaft, a first connecting rod, a second connecting rod, a first transmission rod group, and a second transmission rod group. The cylinder is mounted on the side of the support plate via a second quick-release assembly, and its piston rod end is connected to the fixed shaft. The middle part of the first connecting rod is fixedly connected to the fixed shaft via a first bolt. The two ends of the first connecting rod are slidably connected to guide grooves on the two positioning plates via the second quick-release assembly. The first transmission rod group includes two first transmission rods. One end of each first transmission rod is hinged to the end of the first connecting rod via the second quick-release assembly, and the other end is simultaneously hinged to one end of the corresponding up-mount rod and down-mount rod via the same pivot of the second quick-release assembly. The top of the second connecting rod is fixedly connected to the fixed shaft via a second bolt. The two ends of the second connecting rod are slidably connected to guide grooves on the two positioning plates via the second quick-release assembly. The second transmission rod group includes two second transmission rods. One end of each second transmission rod is movably connected to the end of the second connecting rod via the second quick-release assembly, and the other end is hinged to the middle part of the corresponding up-mount rod and down-mount rod via the second quick-release assembly.

[0006] In a preferred embodiment, the bottom edge of the locking ring is provided with a notch or groove that matches the surface shape of the part to be locked, so as to enhance the stability when locking.

[0007] In a preferred embodiment, the first dovetail groove connection structure includes a dovetail block disposed on the top surface of the fixed plate and a dovetail groove disposed on the bottom surface of the support plate, and the second dovetail groove connection structure includes a dovetail block disposed on the side surface of the positioning plate and a dovetail groove disposed on the side surface of the support plate.

[0008] In a preferred embodiment, the two first transmission rods in the first transmission rod group and the two second transmission rods in the second transmission rod group are each hingedly connected by an independent quick-release assembly.

[0009] In a preferred embodiment, the working component performing the clamping action is an adaptive clamping assembly, which is detachably mounted to the other end of the up-pass and down-passing rods via the quick-release assembly.

[0010] In a preferred embodiment, the adaptive clamping assembly includes: a clamping plate as a mounting base; a plurality of clamping pins arranged along the clamping surface of the clamping plate, each clamping pin being independently slidable in a direction perpendicular to the clamping surface; a plurality of second springs, each second spring correspondingly sleeved on the rear of one of the clamping pins, for providing a preload force to extend the clamping pin forward; and a cam adjustment mechanism including a rotating shaft rotatably mounted within the clamping plate and a cam rod fixed to the rotating shaft, the profile surface of the cam rod simultaneously abutting the rear ends of all the second springs, and the position of the cam rod can be changed by rotating the rotating shaft, thereby synchronously adjusting the initial extension amount of all the clamping pins.

[0011] In a preferred embodiment, the cam adjustment mechanism further includes a ratchet locking structure, which includes a first ratchet ring fixed to the clamp plate, a second ratchet ring fixed to the end of the rotating shaft, and a limiting ring fixed to the end of the rotating shaft. The teeth of the first ratchet ring and the second ratchet ring mesh with each other to prevent the rotating shaft from rotating accidentally after adjustment, while the limiting ring limits the rotating shaft.

[0012] In a preferred embodiment, the clamping plate is provided with a limiting block to limit the maximum stroke of the clamping pin.

[0013] In a preferred embodiment, the pins and locking rings of the quick-release assembly are made of alloy structural steel, and their surfaces are carburized or nitrided; the locking block is made of bearing steel or high-strength alloy steel.

[0014] The present invention has the following beneficial effects: 1. The system utilizes a multi-layered combination of a worktable, fixed plate, support plate, and positioning plate, connected via a dovetail joint structure and standardized quick-release components. The clamping drive assembly is cylinder-driven, forming a precise planar linkage mechanism through a fixed shaft, first connecting rod, second connecting rod, and two symmetrically arranged transmission rods. This mechanism accurately converts the linear motion of the cylinder into synchronous, opposite-facing or opposite-facing movements of the four clamping points (the ends of the upper and lower transmission rods) of the two clamping arm units, ensuring both rapid assembly and disassembly while maintaining uniform distribution of clamping force and repeatable positioning accuracy.

[0015] 2. The quick-release assembly adopts the mechanical locking principle of inclined plane clamping. The locking ring presses down to make the locking block retract, achieving a firm axial lock. Its structure is simple, the operation is quick and the connection rigidity is high, which can meet the vibration and cutting force requirements during the processing.

[0016] 3. The adaptive component uses multiple independent floating clamping pins and preloaded springs, which can independently extend and retract according to the contour of the workpiece contact surface, so that the clamping force is evenly distributed on multiple contact points. This effectively avoids clamping deformation or damage caused by unevenness of the workpiece or thin-walled or easily deformable parts. In addition, the initial extension of all clamping pins can be adjusted synchronously at one time through the cam adjustment mechanism to adapt to slight changes in the size of different batches of workpieces. The ratchet locking structure can prevent loosening, realizing flexible, high-precision and stable adaptive clamping. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The detachable multi-purpose component clamp assembly involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-5 The detachable multi-purpose parts clamping assembly shown includes a worktable 1, a fixed plate 2, a support plate 4, a positioning plate 5, a quick-release assembly 3, a clamping drive assembly 6, and two symmetrically arranged clamping arm units. In this embodiment, it should be noted that the workbench 1 serves as the mounting base for the entire fixture, used for fixed connection with the machine tool or work platform. The fixing plate 2 is fixedly installed on the top of the workbench 1 via the quick-release assembly 3, providing a stable mounting base for the upper structure. The bottom of the support plate 4 is detachably installed above the fixing plate 2 via at least one set of first dovetail groove connection structures. This design allows the support plate 4 to be quickly installed or replaced in the horizontal direction to adapt to different fixture heights or layout requirements. The two positioning plates 5 are detachably installed via second dovetail groove connection structures. On the two opposite sides of the support plate 4, each positioning plate 5 has a guide groove in the vertical direction to constrain the movement trajectory of the clamping arm and ensure its linearity and stability. Multiple quick-release assemblies 3 are configured at each key connection point of the fixture. They include at least a first quick-release assembly for locking the fixed plate 2 on the worktable 1 and multiple second quick-release assemblies for connecting moving parts to achieve quick connection and separation between the parts. The clamping drive assembly 6 is detachably mounted on the side of the support plate 4 through at least one second quick-release assembly as the power source of the fixture. Each clamping arm unit includes an up-pass rod 65 and a down-pass rod 66; one end of the up-pass rod 65 and the down-pass rod 66 is hinged to the clamping drive assembly 6 via a second quick-release assembly, and the middle part of the up-pass rod 65 and the down-pass rod 66 is movably connected to the guide groove on the positioning plate 5 via a sliding pin. The other end of the up-pass rod 65 and the down-pass rod 66 is used to install the working parts that perform the clamping action. The clamping drive assembly 6 is used to drive the up-pass rod 65 and the down-pass rod 66 of the two clamping arm units to move synchronously in opposite directions or in opposite directions, so as to achieve clamping and releasing of the parts.

[0021] Please see Figures 4-5 The detachable multi-purpose parts clamping assembly shown includes a clamping drive assembly 6 comprising a cylinder 60, a fixed shaft 61, a first connecting rod 63, a second connecting rod 67, a first transmission rod group 64, and a second transmission rod group 68. In this embodiment, it should be noted that the cylinder 60 is mounted on the side of the support plate 4 via the second quick-release assembly, and its piston rod end is connected to the fixed shaft 61 as the input of the entire drive mechanism. The middle part of the first connecting rod 63 is fixedly connected to the fixed shaft 61 via the first bolt 62, and its two ends are respectively connected to the guide grooves on the two positioning plates 5 via the second quick-release assembly to form a sliding connection, so that the first connecting rod 63 can move linearly with the fixed shaft 61 and maintain motion accuracy under the constraint of the guide groove. The first transmission rod assembly 64 includes two first transmission rods. One end of each first transmission rod is hinged to the end of the first connecting rod 63 via the second quick-release assembly, and the other end is simultaneously hinged to one end of the corresponding up-transmission rod 65 and down-transmission rod 66 via the rotating shaft of the same second quick-release assembly, thereby converting the linear motion of the first connecting rod 63 into the initial swing of the up-transmission rod 65 and down-transmission rod 66 around their hinge point. The top of the second connecting rod 67 is fixedly connected to the fixed shaft 61 by the second bolt 62. Its two ends are slidably connected to the guide grooves on the two positioning plates 5 by the second quick-release assembly, and move parallel to the first connecting rod 63. The second transmission rod assembly 68 includes two second transmission rods. One end of each second transmission rod is movably connected to the end of the second connecting rod 67 by the second quick-release assembly, and the other end is hinged to the middle of the corresponding up-pass rod 65 and down-pass rod 66 by the second quick-release assembly. This design constitutes a precise planar linkage mechanism that can accurately and synchronously convert the single linear input of the cylinder 60 into the opposing or opposite movements of the four clamping points of the two clamping arm units (i.e., the ends of the two up-pass rods 65 and the ends of the two down-pass rods 66). While ensuring quick assembly and disassembly, it also ensures the uniform distribution of clamping force and the repeatability of positioning.

[0022] Please see Figure 2 The detachable multi-purpose parts clamp assembly shown includes a quick-release component 3 comprising a pin 30, a support shaft 31, a locking block 32, a first spring 33, and a locking ring 34. In this embodiment, it should be noted that the main body of the pin 30 passes through the corresponding through hole on the component to be connected to achieve initial positioning. The two ends of the support shaft 31 are fixed inside the top of the pin 30 to provide rotational support. The middle part of the locking block 32 is provided with a through hole and is rotatably sleeved on the support shaft 31. The two ends of the locking block 32 are accommodated in the sliding groove opened at the top of the pin 30 and can slide along it. The bottom of the locking block 32 is designed as a slope or arc surface. The first spring 33 is provided inside the locking block 32 or abuts against its side to provide an elastic force that makes the two ends of the locking block 32 have an outward opening tendency. The locking ring 34 is sleeved on the pin 30 and located above the component to be locked. When the locking ring 34 slides downward along the pin 30, its inner edge or lower end face presses against the bottom surface of the locking block 32. Utilizing the principle of the inclined plane, the locking block 32 is forced to overcome the elastic force of the first spring 33 and retract inward, thereby locking the component to be locked and firmly locking the pin 30 and its connected components. The bottom edge of the locking ring 34 may have a notch or groove that matches the surface shape of the component to be locked, to enhance stability and anti-torsion capability during locking. By pressing down on the locking ring 34, the locking block 32 retracts, achieving a secure axial lock. Its structure is simple, operation is quick (only requiring pushing and pulling the locking ring 34), and connection rigidity is high, meeting the requirements of vibration and cutting force during processing.

[0023] Please see Figures 4-7 The detachable multi-purpose component clamping assembly shown has an adaptive clamping component 7 that performs the clamping action. It is detachably mounted to the other end of the up-transfer rod 65 and the down-transfer rod 66 via a quick-release component 3. In this embodiment, it should be noted that the adaptive clamping assembly 7 includes a clamping plate 70, multiple clamping pins 77, multiple second springs 76, and a cam adjustment mechanism. The clamping plate 70 serves as a mounting base and is connected to the up-up rod 65 or the down-down rod 66 via the quick-release assembly 3. The multiple clamping pins 77 are arranged along the clamping surface of the clamping plate 70, and each clamping pin 77 can slide independently in a direction perpendicular to the clamping surface. The multiple second springs 76 are respectively sleeved on the rear of one clamping pin 77, providing a preload force to extend the clamping pin 77 forward (towards the workpiece). The cam adjustment mechanism includes a rotating shaft 71 rotatably mounted within the clamping plate 70 and a cam rod 73 fixed to the rotating shaft 71. The profile surface of the cam rod 73 simultaneously abuts against the rear ends of all the second springs 76. By rotating the rotating shaft 71, the position of the cam rod 73 can be changed, thereby synchronously adjusting the initial extension amount of all clamping pins 77 to quickly adapt to the basic requirements of different batches of workpieces. The dimensions include a cam adjustment mechanism that also includes a ratchet locking structure, which consists of a first ratchet ring 74 fixed on the clamping plate 70 and a second ratchet ring 75 fixed to the end of the rotating shaft 71. The teeth of the two ratchet rings mesh to prevent the rotating shaft 71 from rotating accidentally after adjustment, ensuring a stable clamping state. At the same time, a limiting ring 72 limits the rotating shaft 71. A limiting block 78 is also provided in the clamping plate 70 to limit the maximum stroke of the clamping pins 77 and prevent them from overextending or disengaging. When clamping workpieces with irregular surfaces, each clamping pin 77 can float independently under the action of the second spring 76, so that the clamping force is evenly distributed, effectively avoiding excessive local stress or deformation of the workpiece, and realizing flexible adaptive clamping.

[0024] Working principle: During operation, the operator first selects the appropriate support plate 4 and positioning plate 5 according to the size and shape of the part to be processed, and quickly assembles the main frame of the fixture through the first and second dovetail groove connection structure. The fixing plate 2 is locked on the worktable 1 through the first quick release assembly. Then, the clamping drive assembly 6 and clamping arm unit are installed through the quick release assembly 3. If the workpiece shape is complex, the adaptive clamping assembly 7 can be installed at the end of the up-transfer rod 65 and the down-transfer rod 66, and the initial position of the clamping pin 77 is pre-adjusted by rotating the rotating shaft 71.

[0025] After the equipment is started, the cylinder 60 of the clamping drive assembly 6 is activated, driving the piston rod to extend and retract, which in turn drives the fixed shaft 61 and the first connecting rod 63 and the second connecting rod 67 fixed thereto to move synchronously in a straight line. The two ends of the first connecting rod 63 and the second connecting rod 67 slide in the guide groove of the positioning plate 5. The first connecting rod 63 drives one end of the up-up rod 65 and the down-down rod 66 to move through the first transmission rod group 64, while the second connecting rod 67 drives the middle part of the up-up rod 65 and the down-down rod 66 to move through the second transmission rod group 68. Under the precise guidance of the guide groove, this linkage mechanism converts the linear motion of the cylinder 60 into precise synchronous synchronous movement of the four clamping points (or the clamping surfaces of the adaptive clamping assembly 7) of the two clamping arm units towards each other (clamping) or away from each other (releasing).

[0026] When using the adaptive clamping assembly 7, each clamping pin 77, after contacting the workpiece, independently compresses its corresponding second spring 76 according to the contour of the workpiece contact surface, achieving multi-point adaptive contact and ensuring uniform clamping force. After processing, the cylinder 60 reverses its action, driving the clamping arm to release the workpiece. When it is necessary to change the workpiece or adjust the fixture configuration, the quick-release assemblies 3 can be operated quickly to release the locking ring 34. The latch 32 opens under the action of the first spring 33, allowing easy disassembly of the pin 30 and related components, achieving rapid reconfiguration of the fixture.

[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
