Description

Technical Field

[0001] This invention relates to the field of linear module processing equipment technology, and in particular to linear module fixtures. Background Technology

[0002] As a core transmission component in the field of precision automation, the quality of the linear module base directly determines the accuracy and performance of the entire machine.

[0003] Module bases are typically elongated cavity structures. Before assembly, their inner walls and mounting surfaces require high-precision machining using milling machines, machining centers, or other equipment to ensure the required flatness, straightness, and positional accuracy. To accommodate the travel requirements of different application scenarios, module bases come in a variety of length specifications, which places high demands on the versatility and adaptability of their machining fixtures.

[0004] Currently, a multi-linkage specialized fixture is widely used in the industry to fix such long and narrow workpieces. This fixture typically has a series of identical clamping seats arranged in a straight line on a base. Each clamping seat includes a fixed plate, a movable adjusting plate, and a lead screw that drives the adjusting plate.

[0005] To achieve efficient clamping, the lead screws of multiple clamping seats are interconnected through linkage structures such as synchronous belts, chains, or couplings, and are all powered by a drive motor. During operation, the motor starts, and the power is distributed to all lead screws through the linkage structure, driving all adjusting plates to move synchronously, thereby simultaneously clamping or releasing both sides of the module base.

[0006] However, this method of forcing all clamping seats to move synchronously has significant drawbacks. The core problem lies in the lack of adaptability to workpiece length. When machining shorter module bases, only some clamping seats need to participate in clamping to meet the requirement of stable fixation, but clamping seats located outside the workpiece area will still move with the linkage structure. The precision transmission components such as lead screws, nuts, and bearings of these idle clamping seats will undergo unnecessary reciprocating operation and mechanical wear during each clamping process, which will inevitably lead to a shortened service life in the long run.

[0007] Meanwhile, the drive motor must bear the additional frictional force of these idle clamping seat transmission systems during each operation, leading to increased load torque, higher operating current, and accelerated temperature rise. This not only causes unnecessary energy waste but also accelerates motor aging and performance degradation, ultimately affecting the stability and durability of the entire clamping system. Therefore, existing linear module clamps have room for optimization in terms of equipment wear and energy efficiency when dealing with workpieces of different lengths. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0024] Reference Figures 1 to 5 The linear module fixture of this embodiment has a first direction, a second direction, and a third direction, which are orthogonally arranged to each other. Referring to the figure, the first direction is parallel to the X-axis, the second direction is parallel to the Y-axis, and the third direction is parallel to the Z-axis.

[0025] The linear module fixture includes: fixture base 100, clamping component 200, linkage component 300, and clutch component 400.

[0026] The number of clamping components 200 is set to multiple, and the multiple clamping components 200 are arranged at equal intervals along the first direction. The clamping components 200 are installed on the clamp base 100, and the position of the clamping components 200 in the first direction is fixed.

[0027] Specifically, the clamping assembly 200 includes: a fixed clamping structure 210, an adjustable clamping structure 220, and an adjustable lead screw structure 230.

[0028] The fixed clamping structure 210 is fixedly connected to the clamp base 100, and the fixed clamping structure 210 is a thick plate-shaped structure.

[0029] The adjustable clamping structure 220 and the fixed clamping structure 210 are arranged at intervals along the second direction. The adjustable clamping structure 220 is slidably connected to the fixture base 100 along the second direction. The adjustable clamping structure 220 can move closer to or further away from the fixed clamping structure 210 along the second direction to clamp the module base.

[0030] The adjusting screw structure 230 extends along the second direction, and both ends of the adjusting screw structure 230 are rotatably connected to the clamp base 100. The adjusting screw structure is threadedly connected to the adjusting clamping structure 220. When the adjusting screw structure rotates, it drives the adjusting clamping structure 220 to move along the second direction, so that the adjusting clamping structure 220 moves closer to or further away from the fixed clamping structure 210.

[0031] The workpiece detection structure 240 is fixedly mounted on the fixture base 100, and is fixed relative to the fixed clamping structure 210. The workpiece detection structure 240 uses a sensor such as a photoelectric sensor for detection, and is used to detect whether a mold base is placed at the corresponding clamping assembly 200.

[0032] The linkage component 300 includes: a linkage wheel structure 310, a linkage drive structure 330, and a linkage circulation structure 320.

[0033] The linkage wheel structure 310 is rotatably connected to the clamp base 100, and the linkage wheel structure 310 is located at the adjusting screw structure 230. Multiple linkage wheel structures 310 are provided, and each of the multiple linkage wheel structures 310 corresponds to one of the multiple clamping components 200.

[0034] Specifically, the linkage wheel structure 310 is provided with a second linkage connection part 311. In this embodiment, the second linkage connection part 311 is set as an internal spline structure. In other embodiments, the second linkage connection part 311 can also be set as a conventional keyway structure. Those skilled in the art can select the specific structure of the second linkage connection part 311 according to actual needs.

[0035] The linkage drive structure 330 is configured as a servo motor and is fixedly mounted on the frame. The output end of the linkage drive structure 330 is fixedly connected to one of the linkage wheel structures 310 to drive the linkage wheel structure 310 to rotate.

[0036] The linkage loop structure 320 bypasses multiple linkage wheel structures 310 and is connected to the linkage wheel structures 310 in a transmission manner. By setting the linkage loop structure 320, when the linkage drive structure 330 drives one of the linkage wheel structures 310 to rotate, multiple linkage wheel structures 310 rotate synchronously. Specifically, in this embodiment, the linkage wheel structure 310 is set as a sprocket, and the linkage loop structure 320 is set as a chain (the linkage loop structure 320 is represented by a line segment in the figure). In other embodiments, the linkage wheel structure 310 can also be set as a synchronous belt pulley, and the linkage loop structure 320 can be set as a synchronous belt. Those skilled in the art can choose the specific construction of the linkage wheel structure 310 and the linkage loop structure 320 according to actual needs.

[0037] The clutch assembly 400 includes: a clutch sleeve structure 410, a clutch control structure 420, and a clutch reset structure 430.

[0038] The number of clutch sleeve structures 410 is set to multiple, and the multiple clutch sleeve structures 410 are respectively set to correspond to the adjusting screw structures 230 of multiple clamping assemblies 200.

[0039] The clutch sleeve structure 410 is disposed between the adjusting screw structure 230 and the linkage wheel structure 310. The clutch sleeve structure 410 is installed at the end of the corresponding adjusting screw structure 230. The clutch sleeve structure 410 can slide relative to the adjusting screw structure 230 in the second direction, and the clutch sleeve structure 410 is connected to the adjusting screw structure 230 in a transmission connection.

[0040] Specifically, in this embodiment, the clutch sleeve structure 410 is provided with a first clutch connection structure, and the end of the adjusting screw structure 230 is provided with a second clutch connection structure. The first clutch connection structure and the second clutch connection structure are connected in a transmission manner. Specifically, in this embodiment, the first clutch connection structure is configured as an internal spline, and the second clutch connection structure is configured as an external spline. By configuring the first clutch connection structure and the second clutch connection structure as internal splines and external splines respectively, when the clutch sleeve structure 410 moves relative to the adjusting screw structure 230 in the second direction, the clutch sleeve structure 410 and the adjusting screw structure 230 maintain transmission, so that the clutch sleeve structure 410 rotates with the adjusting screw structure 230.

[0041] Specifically, the clutch sleeve structure 410 is provided with a first linkage connection part 411. In this embodiment, the first linkage connection part 411 is configured as an external spline so that the shape of the first linkage connection part 411 matches that of the second linkage connection part 311. The first linkage connection part 411 is used to insert and connect with the second linkage connection part 311 to realize the transmission between the clutch sleeve structure 410 and the linkage wheel structure 310. When the clutch sleeve structure 410 moves relative to the linkage wheel structure 310 in the second direction, the first linkage connection part 411 and the second linkage connection part 311 separate or insert and engage to control the transmission between the clutch sleeve structure 410 and the linkage wheel structure 310.

[0042] In other embodiments, the first linkage connection part 411 can also be set as a conventional key protrusion structure. Those skilled in the art can select the specific structure of the first linkage connection part 411 according to actual needs, so that the first linkage connection part 411 and the second linkage connection part 311 can cooperate with each other to realize the cooperation of the clutch sleeve structure 410 and the linkage wheel structure 310.

[0043] The clutch sleeve structure 410 has two connection states, designated as the first state and the second state. In the first state, the first linkage connection part 411 and the second linkage connection part 311 are in an inserted state to achieve the transmission connection between the clutch sleeve structure 410 and the linkage wheel structure 310. In the second state, the first linkage connection part 411 and the second linkage connection part 311 are in a separated state to achieve the separation between the clutch sleeve structure 410 and the linkage wheel structure 310. In the second state, the linkage wheel structure 310 rotates freely, and the adjusting screw structure 230 of the idle clamping assembly 200 does not rotate. The linkage drive structure 330 does not need to bear the additional friction of the idle clamping assembly 200 during operation, thereby reducing the load on the linkage drive structure 330 and extending its service life to a certain extent.

[0044] Specifically, the clutch sleeve structure 410 is provided with a first clutch control part 412, which is an annular protrusion structure that surrounds the outer peripheral surface of the clutch sleeve structure 410.

[0045] The clutch control structure 420 is located beside the clamping assembly 200. The clutch control structure 420 includes a guide rail 421, a clutch control element 425, and a clutch control drive element.

[0046] The clutch control drive is fixedly mounted on the frame. In this embodiment, the clutch control drive is set as a lead screw linear module, and the driving direction of the clutch control drive is parallel to the first direction.

[0047] In other embodiments, the clutch control drive can be configured as a synchronous belt linear module, or the clutch control drive structure can be configured as other commonly used linear drive devices such as linear cylinders or linear motors. Those skilled in the art can select the specific structure of the clutch control drive according to actual needs.

[0048] Specifically, the guide rail 421 includes a drive section 423, an arc-shaped connecting section 424, and a control section 422. The drive section 423, the arc-shaped connecting section 424, and the control section 422 are connected in sequence.

[0049] The drive segment 423 is correspondingly arranged with the clutch control drive component. The drive segment 423 and the control segment 422 are arranged along a third direction. An arc-shaped connecting segment 424 is disposed between the drive segment 423 and the control segment 422 to connect them. The drive segment 423 is positioned above the control segment 422. In other embodiments, the drive segment 423 may also be positioned below the control segment 422. Those skilled in the art can select the positional relationship between the drive segment 423 and the control segment 422 according to actual needs.

[0050] In this embodiment, the drive segment 423 is arranged parallel to the first direction, making the arc-shaped control segment 422 a semi-circular arc track structure, and the guide track 421 as a whole U-shaped structure. In other embodiments, the drive segment 423 may also be arranged parallel to a third direction. Those skilled in the art can select the length direction of the drive segment 423 according to actual needs.

[0051] By configuring the guide rail 421 into a structure containing multiple segments and arranging the drive section 423 and the control end in the vertical direction, the space occupied by the guide rail 421 as a whole in the first direction can be reduced, thereby reducing the space occupied by the linear mold fixture as a whole in the first direction, so as to ensure that the linear mold fixture can be installed on the processing equipment.

[0052] Specifically, in this embodiment, the clutch control component 425 includes a plurality of clutch control units 426. The plurality of clutch control units 426 are closely arranged along the guide rail 421, and the clutch control units 426 are slidably connected to the guide rail 421. Specifically, two adjacent clutch control units 426 are hinged together, with the hinge point of two adjacent clutch control units 426 located at the center of their respective ends, so that the clutch control component 425 as a whole is bendable, allowing the clutch control component 425 as a whole to adapt to the deformation of the path of the guide rail 421.

[0053] Specifically, in this embodiment, the clutch control unit 426 slides with the guide rail 421 through a roller structure to reduce friction between the two.

[0054] The clutch control unit 426 located at the end is fixedly connected to the output end of the clutch control drive, so that the clutch control drive can drive the clutch control unit 426 to move along the guide rail 421.

[0055] The clutch control unit 425 is provided with a second clutch control section.

[0056] The second clutch control unit is located at the clutch control unit 426 at the end. Specifically, the second clutch control unit has a first clutch control surface and a second clutch control surface, which are connected to each other.

[0057] In this embodiment, the first clutch control surface is configured as a flat, inclined structure, gradually moving away from the linkage wheel structure 310 in a direction away from the arc-shaped connecting section 424. When the first clutch control surface moves along the first direction, the second clutch control part abuts against the first clutch control surface. As the first clutch control surface continues to move, the second clutch control part is driven by the first clutch control surface to move along the second direction, thereby driving the clutch sleeve structure 410 away from the linkage wheel structure 310, causing the clutch sleeve structure 410 to switch to the second state.

[0058] The clutch reset structure 430 is configured as a spring structure and is located between the clutch sleeve structure 410 and the adjusting screw structure 230. The clutch reset structure 430 ensures that the clutch sleeve structure 410 always tends to move closer to the linkage wheel structure 310. After the external force applied to the clutch sleeve structure 410 by the clutch control element 425 disappears, the clutch reset structure 430 automatically moves closer to the linkage wheel structure 310, returning the clutch reset structure 430 to the first state. This achieves the reconnection of the clutch reset structure 430 and the linkage wheel structure 310, allowing the clutch reset structure 430 to rotate with the linkage wheel structure 310.

[0059] In other embodiments, the first clutch control surface may also be configured as an arc surface structure, and those skilled in the art can select the specific structure of the second clutch control part according to actual needs.

[0060] In other embodiments, the first state can be set as a state where the first linkage connection part 411 and the second linkage connection part 311 are separated, and the second state can be set as a state where the first linkage connection part 411 and the second linkage connection part 311 are plugged into each other. Correspondingly, in the direction away from the arc-shaped connecting section 424, the first clutch control surface gradually approaches the linkage wheel structure 310, and the clutch reset structure 430 ensures that the clutch sleeve structure 410 always tends to move away from the linkage wheel structure 310. Those skilled in the art can select the engagement state of the first linkage connection part 411 and the second linkage connection part 311 in each connection state according to actual needs.

[0061] Reference Figure 6 The method of using this linear module fixture includes the following steps: S100. Place the module base into the linear module fixture; S200 drives the multiple linkage wheel structure 310 to rotate, and the clutch sleeve structure 410 in the first state drives the adjusting screw structure 230 to return to the initial state. S300. Adjust the clutch control structure 420 according to the length of the module base to adjust the number of clutch sleeve structures 410 in the first state. S400 drives multiple linkage wheel structures 310 to rotate, and the clutch sleeve structure 410 in the first state drives the corresponding adjusting screw structure 230 to rotate, so that the corresponding clamping component clamps the module base.

[0062] The working process of this linear module fixture is as follows: In the initial state, all clutch sleeve structures 410 are in the first state under the action of the return spring, at which time the first linkage connection part 411 and the second linkage connection part 311 are in the plugging state.

[0063] The staff then places the module base on the linear module fixture. The workpiece detection structure 240 of the clamping component 200 will detect whether a workpiece is placed on it and transmit the signal to the control system.

[0064] The control system sends a signal to the clutch control drive, causing the clutch control drive to drive the second clutch control unit to move to the first clamping assembly 200 where no module base is detected, causing the clutch sleeve structure 410 of the multiple clamping assemblies 200 that have not detected the module base to switch to the second state, so as to adjust the number of clutch sleeve structures 410 in the first state.

[0065] Subsequently, the linkage wheel drive component drives multiple linkage wheel structures 310 to rotate synchronously through the linkage circulation structure 320, causing the adjusting screw structures 230 of multiple clamping components 200 to rotate simultaneously. Only those clutch sleeve structures 410 in the first state will drive their corresponding adjusting screw structures 230 to rotate, so that the clamping components 200 that detect the module base will clamp the module base at multiple points. The linkage wheel structures 310 corresponding to the clamping components 200 in the second state of the clutch sleeve structure 410 will idle, so as to reduce the load on the linkage wheel drive component, extend the service life of the linkage wheel drive component, and reduce energy waste.
