Abstract
Description
Technical Field
[0001] This utility model relates to the field of locking fixtures and clamps, and in particular to a quick-locking fixture and clamp to prevent distortion. Background Technology
[0002] In the field of CNC machining, tooling fixtures serve as key auxiliary equipment in the batch processing of parts. Their main function is to achieve rapid positioning and reliable locking of parts, directly affecting machining accuracy, production efficiency, and ease of operation. For continuous processing of batch parts, tooling fixtures must possess stable structural rigidity, efficient locking capabilities, and good adaptability to meet the clamping requirements of parts of different specifications, while reducing clamping time and improving the overall operating efficiency of the production line.
[0003] However, existing tooling fixtures for CNC machining still have shortcomings in practical applications:
[0004] Some tooling fixtures have unreasonable guide structure designs and do not use precision slider tracks, which can easily lead to uneven force and deviation of the movement trajectory during the movement of the locked product, resulting in lock distortion and failure to achieve effective and fast locking. This not only affects the positioning accuracy of the parts, but may also increase the machining error due to unstable clamping.
[0005] Therefore, we propose a quick-locking fixture to prevent distortion. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of existing technologies. Some tooling fixtures have unreasonable guide structure designs and do not use precision slider tracks, which can lead to uneven force and movement trajectory deviation during the movement of the locked product, resulting in lock distortion and failure to achieve effective and fast locking. This not only affects the positioning accuracy of the parts but may also increase processing errors due to unstable clamping.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A quick-locking fixture for preventing distortion includes: a fixed base, which is fixedly mounted on a support surface; a support base, which is fixedly mounted on the fixed base; and a transmission mechanism, which is mounted together on the support base and the fixed base.
[0009] A moving and guiding mechanism is mounted on a fixed base. The moving and guiding mechanism includes a drive connection end and two limiting guide sliding ends. The drive connection end is threadedly connected to a transmission mechanism. Both limiting guide sliding ends are mounted on the fixed base and together guide and restrict the sliding of the drive connection end. Two self-lubricating mechanisms are also included, each mounted on one of the two limiting guide sliding ends. Each self-lubricating mechanism includes a storage and adding component and two lubricating oil components. The storage and adding component is located on the limiting guide sliding end, and the two lubricating oil components are located on both sides below the storage and adding component for lubricating the moving and guiding mechanism.
[0010] Several abutting slider structures are fixedly installed on the moving and guiding mechanism. These abutting slider structures are used in conjunction with the self-lubricating mechanism to release lubricating oil.
[0011] As a preferred embodiment of this utility model, the transmission mechanism includes: a mounting block, which is fixedly disposed on the top of the fixed seat and located on the opposite side of the support seat; a first bearing, which is fixedly disposed inside the mounting block; a second bearing, which is fixedly disposed inside the support seat; a ball screw, with its two ends respectively mounted on the second bearing and the first bearing, and the ball nut on the ball screw connected to the drive movement and guide mechanism; a rotating rod, which is connected to one end of the ball screw; and a rotating handle, which is fixedly disposed on the rotating rod.
[0012] As a preferred embodiment of this utility model, the drive connection end includes: a movable clamping seat; a lead screw copper sleeve, which is disposed at the center inside the movable clamping seat, and is connected to the ball nut of the ball screw, and the lead screw copper sleeve is threadedly engaged with the ball screw.
[0013] As a preferred embodiment of this utility model, the limiting guide sliding end includes: a sliding block, which is fixedly disposed at the bottom of the movable clamping seat; and a guide rail, which is fixedly disposed at the top of the fixed seat and is slidably connected to the sliding block.
[0014] As a preferred embodiment of this utility model, the storage and adding component includes: a storage groove, which is located at the top inside the sliding block; an adding tube, which is located on the outer wall of the storage groove, with one end of the adding tube connected to the outside and the other end connected to the storage groove; and a threaded sealing cap, which is threadedly connected to the inlet end of the adding tube.
[0015] As a preferred embodiment of this utility model, the lubricating oil lubrication component includes: two connecting pipes located at the bottom of a storage tank, with their inlet ends connected to the storage tank; an oil outlet pipe connected to the connecting pipes; an outer contact slide rail located on the sliding surface of the sliding block, with the outlet end of the oil outlet pipe corresponding to the outer contact slide rail; an inner fixing ring fixedly disposed at the inlet end of the oil outlet pipe; a mounting base disposed inside the oil outlet pipe; a spring fixedly disposed between the inner fixing ring and the mounting base; an outer fixing limiting ring fixedly disposed at the outlet end of the oil outlet pipe, restricting the mounting base from moving out of the outlet end of the oil outlet pipe; and a sealing ball fixedly disposed on the mounting base, sealing the internal channel of the outer fixing limiting ring.
[0016] As a preferred embodiment of this utility model, the abutting slider structure includes: a slider body, which is fixedly mounted on the sliding surface of the guide rail and used in conjunction with the outer abutting track; and inclined surfaces, which are located at both ends of the slider body.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] In this invention, two limiting guide sliding ends (sliding blocks and guide rails sliding together) are set through the moving and guiding mechanism. Combined with the precise connection between the ball screw and the bearing in the transmission mechanism, it is ensured that the moving clamping seat has a precise trajectory and balanced force during the sliding process. This avoids the problems of motion trajectory deviation and lock distortion caused by unreasonable guide structure in existing tooling, significantly improves the effectiveness and speed of locking, and ensures the positioning accuracy of part clamping.
[0019] The transmission mechanism uses a ball screw and a screw copper sleeve threaded to the drive connection end. By turning the handle, the moving clamp can be driven to move stably along the guide rail. It can adapt to products of different sizes without frequent manual adjustment of the overall position of the tooling. This solves the problem of cumbersome and time-consuming operation when the existing tooling is used for products with inconsistent specifications, and effectively improves the continuity and efficiency of mass production.
[0020] The self-lubricating mechanism's storage tank stores lubricating oil. When the slide bar body of the contact slide bar structure engages with the outer contact slide rail, its inclined surface triggers the sealing ball to disengage from the outer fixed limiting ring, allowing the lubricating oil to be automatically released to the sliding part through the connecting pipe and oil outlet pipe. During sliding, the oil supply stops when the sealing ball resets, forming a continuous and effective lubrication mechanism. This design solves the problems of increased frictional resistance, poor sliding, and accelerated wear caused by insufficient lubrication in the sliding parts of existing tooling, significantly improving the stability and service life of the tooling.

[0031] Example
[0032] like Figures 1-5 As shown, this utility model provides a technical solution: a quick-locking fixture to prevent distortion, characterized in that it includes:
[0033] Fixed seat 10, the fixed seat 10 is fixedly mounted on the support surface;
[0034] Support base 20, the support base 20 is fixedly mounted on the fixed base 10;
[0035] The transmission mechanism 30 is mounted together on the support base 20 and the fixed base 10;
[0036] The moving and guiding mechanism 40 is mounted on the fixed base 10. The moving and guiding mechanism 40 includes a drive connection end and two limiting guide sliding ends. The drive connection end is threadedly connected to the transmission mechanism 30. The two limiting guide sliding ends are both set on the fixed base 10. The two limiting guide sliding ends are used together to guide and limit the sliding of the drive connection end.
[0037] Two self-lubricating mechanisms 50 are respectively installed on two limiting guide sliding ends. Each self-lubricating mechanism 50 includes a storage and adding component and two lubricating components. The storage and adding component is set on the limiting guide sliding end, and the two lubricating components are set on both sides below the storage and adding component for lubricating the moving and guiding mechanism 40.
[0038] Several abutting slider structures 60 are fixedly mounted on the moving and guiding mechanism 40, and are used in conjunction with the self-lubricating mechanism 50 to release lubricating oil.
[0039] The fixed base 10 provides basic support for the overall structure, and the support base 20 serves as the end mounting reference for the transmission mechanism 30. When the transmission mechanism 30 is running, the drive connection end converts the rotational motion into linear motion through threaded engagement, driving the movement and guide mechanism 40 to move. The two limit guide sliding ends limit the direction of movement through sliding engagement to prevent deviation. In the self-lubricating mechanism 50, the storage adder stores lubricating oil. When the contact slide bar structure 60 moves with the movement and guide mechanism 40, it squeezes the sealing component of the lubricating oil, releasing the lubricating oil to the sliding contact surface to achieve dynamic lubrication. Multiple contact slide bar structures 60 ensure continuous triggering of lubrication throughout the movement, ensuring smooth sliding, achieving rapid and stable locking of the workpiece, and preventing distortion.
[0040] The transmission mechanism 30 includes:
[0041] Mounting block 301 is fixedly mounted on the top of the fixed base 10 and located on the opposite side of the support base 20;
[0042] The first bearing 302 is fixedly installed inside the mounting block 301;
[0043] The second bearing 305 is fixedly installed inside the support base 20;
[0044] The ball screw 304 has two ends mounted on the second bearing 305 and the first bearing 302 respectively, and the ball nut on the ball screw 304 is connected to the drive movement and guide mechanism 40.
[0045] Rotating rod 303 is connected to one end of ball screw 304;
[0046] Rotate handle 306, which is fixedly mounted on rotating rod 303.
[0047] When the handle 306 is turned, the rotating rod 303 rotates under the support of the first bearing 302 and the second bearing 305, driving the ball screw 304 to rotate synchronously. The ball screw 304 uses the principle of the screw pair to convert the rotational motion into linear motion, driving the moving and guiding mechanism 40 to move along the screw axis in the ball screw 304. The use of the first bearing 302 and the second bearing 305 reduces rotational friction, ensures transmission accuracy and smoothness, provides stable power output for the moving and guiding mechanism 40, and realizes rapid adjustment of the workpiece clamping position.
[0048] The driver connection includes:
[0049] Movable clamping base 401;
[0050] The lead screw copper sleeve 402 is located at the center inside the movable clamping seat 401. The lead screw copper sleeve 402 is connected to the ball nut of the ball screw 304, and the lead screw copper sleeve 402 is threadedly engaged with the ball screw 304.
[0051] When the ball screw 304 rotates, the rotational motion of the ball screw 304 is converted into linear motion through the helical engagement between the ball nut on the ball screw 304 and the screw on the ball screw 304, and the threaded engagement between the screw copper sleeve 402 and the screw on the ball screw 304. This linear motion drives the movable clamping seat 401 to move along the limiting guide sliding end. The screw copper sleeve 402 is made of copper and has wear-resistant and self-lubricating properties. When it is engaged with the ball screw 304, the transmission efficiency is high and the clearance is small, ensuring the displacement accuracy of the movable clamping seat 401 and providing a stable linear motion basis for workpiece locking.
[0052] The limiting guide sliding end includes:
[0053] Sliding block 403 is fixedly disposed at the bottom of movable clamping seat 401;
[0054] The guide slide rail 404 is fixedly mounted on the top of the fixed base 10, and the guide slide rail 404 is slidably connected to the sliding block 403.
[0055] When the movable clamping seat 401 is driven to move by the ball screw 304, the sliding block 403 is embedded in the groove of the guide rail 404 and slides along the length of the rail. The groove structure of the guide rail 404 restricts the movement direction of the sliding block 403 (only along the axial direction of the rail), avoiding lateral offset or torsion during movement, ensuring that the movement trajectory of the movable clamping seat 401 is straight, preventing the lock distortion caused by uneven force, and improving the stability and accuracy of locking.
[0056] Storage add-ons include:
[0057] Storage slot 501 is located at the top inside the sliding block 403;
[0058] Adding tube 502 is provided on the outer wall of storage tank 501. One end of adding tube 502 is connected to the outside, and the other end of adding tube 502 is connected to storage tank 501.
[0059] Threaded sealing cap 503 is threadedly connected to the inlet end of adding tube 502.
[0060] Storage tank 501 is used to store lubricating oil and provide a medium for the self-lubricating system. When replenishing lubricating oil, unscrew the threaded sealing cap 503 and inject lubricating oil into storage tank 501 through addition pipe 502. After replenishment, tighten the threaded sealing cap 503 to prevent lubricating oil leakage. Storage tank 501 is located on top of sliding block 403 and uses gravity to assist the lubricating oil to flow to the lubricating components below, ensuring the continuous liquid supply capacity of the lubrication system.
[0061] Lubricating oil lubrication components include:
[0062] There are two connecting pipes 504, which are located at the bottom of the storage tank 501 and are connected to the inlet end of the connecting pipe 504.
[0063] Oil outlet pipe 505, the inlet end of oil outlet pipe 505 is connected to connecting pipe 504;
[0064] The outer contact slide 506 is formed on the sliding surface of the sliding block 403, and the outlet end of the oil pipe 505 corresponds to the outer contact slide 506.
[0065] The inner fixing ring 507 is fixedly installed at the inlet end of the oil outlet pipe 505;
[0066] Mounting base 508 is located inside the oil outlet pipe 505;
[0067] Spring 509 is fixedly disposed between inner fixing ring 507 and mounting base 508;
[0068] An external fixed limiting ring 510 is fixedly installed at the outlet end of the oil outlet pipe 505 and restricts the mounting base 508 from moving out of the outlet end of the oil outlet pipe 505.
[0069] The sealing sphere 511 is fixedly mounted on the mounting base 508 and blocks the internal channel of the externally fixed limiting ring 510.
[0070] Under normal conditions, spring 509 pushes mounting base 508, causing sealing ball 511 to press tightly against outer fixed limit ring 510, sealing oil outlet pipe 505. When sliding block 403 moves along guide rail 404, abutting slide bar structure 60 enters outer abutting slide channel 506, squeezing sealing ball 511, causing spring 509 to compress, sealing ball 511 to disengage from outer fixed limit ring 510, and lubricating oil in storage tank 501 flows out through connecting pipe 504 and oil outlet pipe 505, lubricating the contact surface between sliding block 403 and guide rail 404. After slide bar leaves, spring 509 resets, sealing ball 511 re-seals, realizing on-demand lubrication of "follow-up oil supply and off-position sealing", reducing friction and wear.
[0071] The abutment slider structure 60 includes:
[0072] The slider body 601 is fixedly mounted on the sliding surface of the guide rail 404 and cooperates with the outer abutting slide 506.
[0073] Inclined surface 602 is located at both ends of slider body 601.
[0074] The slider body 601 is arranged along the length of the guide rail 404. When the slider block 403 moves, the sealing ball 511 contacts the inclined surface 602 of the slider body 601. The inclination angle of the inclined surface 602 generates radial thrust, which pushes the sealing ball 511 to compress the spring 509, triggering the release of lubricating oil. Multiple sliders are arranged at intervals to ensure that the sliding block 403 triggers lubrication once every certain distance during the entire movement, ensuring that the friction surface is continuously oiled. The gradual angle of the inclined surface 602 makes the thrust change smoothly, avoiding impact on the sealing ball 511 and extending the service life of the component. At the same time, it works with the self-lubricating mechanism 50 to achieve dynamic and efficient lubrication.
[0075] Work process summary
[0076] Initial state preparation
[0077] The fixed seat 10 is firmly supported on the working plane, and the support seat 20 and the mounting block 301 fix the two ends of the transmission mechanism 30 respectively; the movable clamping seat 401 is threadedly engaged with the ball screw 304 through the lead screw copper sleeve 402 and is initially located in the clamping position; in the self-lubricating mechanism 50, the sealing ball 511 presses the outer fixed limit ring 510 tightly under the elastic force of the spring 509, closes the oil outlet pipe 505, the storage tank 501 pre-stores lubricating oil, and the abutting slide structure 60 is embedded in the guide slide rail 404 and ready to be used.
[0078] Transmission mechanism 30 drives motion
[0079] Operation trigger: Manually rotate the handle 306 to drive the rotating rod 303 to rotate around the first bearing 302 and the second bearing 305.
[0080] Power conversion: The rotating rod 303 rotates synchronously with the ball screw 304. Utilizing the principle of the screw pair, the rotational motion is converted into the linear motion of the screw sleeve 402, which in turn drives the movable clamping seat 401 to move axially along the ball screw 304, moving it closer to or away from the workpiece clamping position.
[0081] The guiding mechanism restricts the movement trajectory
[0082] When the moving clamp 401 is displaced, the bottom sliding block 403 engages with the groove of the guide rail 404 and slides along the length of the rail.
[0083] The groove structure of the guide rail 404 forcibly constrains the movement direction of the sliding block 403 (only along the axial direction of the rail), avoiding lateral offset and torsion during movement, eliminating the hidden danger of "lock distortion" from the structure, and ensuring clamping accuracy.
[0084] Self-lubricating mechanism with dynamic oil supply.
[0085] When the movable clamping seat 401 drives the sliding block 403 to slide along the guide rail 404, the inclined surface 602 of the sliding bar structure 60 continuously triggers lubrication.
[0086] Compression sealing: The slide bar body 601 enters the outer contact slide 506, the inclined surface 602 compresses the sealing ball 511, compressing the spring 509, and the sealing ball 511 disengages from the outer fixed limit ring 510, opening the oil outlet channel.
[0087] Lubricating oil release: The lubricating oil in the storage tank 501 flows out through the connecting pipe 504 and the oil outlet pipe 505, lubricating the contact surface between the sliding block 403 and the guide rail 404, reducing frictional resistance.
[0088] Reset seal: After the slide bar leaves the outer contact slide 506, the spring 509 pushes the mounting base 508 to reset, and the sealing ball 511 re-tightens the outer fixed limit ring 510, sealing the oil outlet channel and preventing lubricating oil leakage.
[0089] Multiple contacting slider structures are arranged at intervals of 60 to ensure continuous and segmented lubrication of the slider block 403 throughout its movement, ensuring smooth sliding and extending the service life of the component.
[0090] Workpiece locking and clamping completed
[0091] After the movable clamping seat 401 moves to the target position along the ball screw 304, it contacts the workpiece through its own clamping structure (or with the help of auxiliary positioning parts). Utilizing the helical self-locking characteristic of the transmission mechanism 30 (the threaded fit of the ball screw 304 and the copper sleeve has reverse self-locking capability), the workpiece is stably locked, the clamping is completed, and the process begins.
[0092] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
