Description
Technical Field
[0001] This utility model relates to the field of machining tooling technology, specifically to a four-axis tooling that facilitates quick clamping of parts. Background Technology
[0002] In the flexible production scenario of a four-axis machining center, tooling is the core component for achieving precise positioning and stable fixation of parts. Its clamping efficiency and convenience directly determine the overall production rhythm of the machining center.
[0003] In the part fixing process, existing four-axis tooling generally adopts the traditional fixing structure of "clamping block and bolt". During clamping, the clamping block needs to be pushed to the workpiece by repeatedly turning the bolt to achieve locking. During disassembly, the bolt needs to be turned in the opposite direction to loosen the clamping block to release the workpiece. The entire process relies on the mechanical transmission of the bolt to complete the fixing and release, which is cumbersome and inconvenient and seriously restricts the efficiency and flexible production capacity of four-axis machining. Utility Model Content
[0004] In view of the technical problems existing in the background art, this utility model provides a four-axis tooling that facilitates quick clamping of parts.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A four-axis tooling for quick clamping of parts includes a fixture body and a workpiece. The fixture body includes a connecting seat. First abutments are fixedly connected to both sides of the top of the connecting seat, and second abutments are fixedly connected to the other two sides of the top of the connecting seat. A movable hole is provided at the center of the top of the connecting seat. A first sliding groove and a second sliding groove are provided circumferentially along the axis of the movable hole on the top surface of the connecting seat. The first sliding groove and the second sliding groove are arranged in a cross shape. A first moving block is slidably connected to both ends of the interior of the first sliding groove. A first clamping block is fixedly connected to the top of the first moving block. A second moving block is slidably connected to both ends of the interior of the second sliding groove. A second clamping block is fixedly connected to the top of the second moving block. The workpiece is positioned at the top of the connecting seat, with its outer side abutting against the inner sides of the first and second abutting blocks, and its inner side abutting against the outer sides of the first and second clamping blocks. Optionally, a pneumatic telescopic rod is provided inside the movable hole. The pneumatic telescopic rod is fixedly connected to the connecting seat, and four rollers are provided circumferentially at the outer end of the output rod of the pneumatic telescopic rod.
[0006] Optionally, the opposing ends of a pair of first moving blocks and a pair of second moving blocks extend into the interior of the movable hole, and the opposing ends of the first moving blocks and the second moving blocks are provided with wedge-shaped surfaces, with the rollers rollingly connected to the wedge-shaped surfaces.
[0007] Optionally, both sides of the first and second slides are provided with moving grooves, and both sides of the first and second moving blocks are rotatably connected with several pulleys, which are rolledly connected to the moving grooves.
[0008] Optionally, a connecting groove is provided at the opposite ends of a pair of first moving blocks and a pair of second moving blocks, and a spring is fixedly connected in the connecting groove. The other end of the spring abuts against the two ends of the first sliding groove and the second sliding groove, respectively.
[0009] Optionally, the bottom end of the connector is provided with several connecting holes, and the top surface of the connector is provided with a baffle at the position of the movable hole.
[0010] Optionally, dustproof blocks are connected to the opposite ends of the first and second movable blocks, and slots are provided at both ends of the first and second slides, with the dustproof blocks and slots slidably connected.
[0011] This utility model has the following advantages and beneficial effects: This four-axis tooling facilitates rapid workpiece clamping. The mounting base of the clamping body provides a stable foundation for workpiece clamping. The first and second abutments initially limit the workpiece from the outside, preventing workpiece displacement. The first and second sliding grooves, arranged in a cross shape, provide sliding paths for the first and second moving blocks, causing them to drive the first and second clamping blocks to clamp the workpiece from the inside. This, in conjunction with the outer abutments, forms a two-way fixing structure of "outer abutment and inner clamping," facilitating rapid workpiece clamping and ensuring that the workpiece is not easily loosened during four-axis machining, thus improving machining accuracy and clamping efficiency. The pneumatic telescopic rod in the movable hole provides stable power, and its four rollers at the output end rise and fall synchronously with the pneumatic telescopic rod. By cooperating with the wedge-shaped surface, the longitudinal power is converted into lateral thrust, driving the first and second moving blocks to move synchronously, realizing multi-directional linkage control of the clamping blocks. This eliminates the need to drive each clamping component separately, simplifying the operation process and improving clamping speed. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0015] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0016] Example like Figures 1-6 As shown, a four-axis tooling for quick clamping of parts includes a fixture body 1 and a workpiece 2. The fixture body 1 includes a connecting seat 101. First abutments 102 are fixedly connected to both sides of the top of the connecting seat 101. Second abutments 103 are fixedly connected to the other two sides of the top of the connecting seat 101. A movable hole 105 is provided at the center of the top of the connecting seat 101. A first sliding groove 106 and a second sliding groove 107 are provided circumferentially along the axis of the movable hole 105 on the top surface of the connecting seat 101. The first sliding groove 106 and the second sliding groove 107 are arranged in a cross shape. A first moving block 109 is slidably connected to both ends of the interior of the first sliding groove 106. A first clamping block 110 is fixedly connected to the top of the first moving block 109. A second moving block 108 is slidably connected to both ends of the interior of the second sliding groove 107. A second clamping block 111 is fixedly connected to the top of the second moving block 108. The workpiece 2 is positioned at the top of the connecting seat 101. The outer side of the workpiece 2 abuts against the inner side of the first abutment block 102 and the second abutment block 103, respectively, and the inner side of the workpiece 2 abuts against the outer side of the first clamping block 110 and the second clamping block 111, respectively.
[0017] Furthermore, a pneumatic telescopic rod 112 is provided inside the movable hole 105. The pneumatic telescopic rod 112 is fixedly connected to the connecting seat 101. Four rollers 113 are arranged circumferentially at the outer end of the output rod of the pneumatic telescopic rod 112. The pneumatic telescopic rod 112 inside the movable hole 105 can provide stable power. The four rollers 113 at its output end rise and fall synchronously with the pneumatic telescopic rod 112. By cooperating with the wedge surface 116, the longitudinal power is converted into lateral thrust, driving the first moving block 109 and the second moving block 108 to move synchronously, realizing the linkage control of the multi-directional clamping blocks. There is no need to drive each clamping component separately, simplifying the operation process and improving the clamping speed.
[0018] Furthermore, the opposing ends of a pair of first moving blocks 109 and a pair of second moving blocks 108 extend into the interior of the movable hole 105. The opposing ends of the first moving blocks 109 and the second moving blocks 108 are provided with wedge-shaped surfaces 116. The rollers 113 are in rolling connection with the wedge-shaped surfaces 116. The wedge-shaped surfaces 116 of the first moving blocks 109 and the second moving blocks 108 are in rolling connection with the rollers 113, which converts the longitudinal extension and retraction of the pneumatic telescopic rod 112 into the lateral sliding of the moving blocks. By dispersing the force through the inclined surface contact, the first moving blocks 109 and the second moving blocks 108 are subjected to uniform force and move smoothly. The four rollers 113 correspond to the four wedge-shaped surfaces 116, ensuring that the first moving blocks 109 and the second moving blocks 108 move synchronously, realizing uniform clamping of the inner side of the workpiece 2, and avoiding workpiece displacement caused by unilateral force.
[0019] Furthermore, both sides of the first slide groove 106 and the second slide groove 107 are provided with moving grooves 117. Both sides of the first moving block 109 and the second moving block 108 are rotatably connected with several pulleys 118. The pulleys 118 are rolled in connection with the moving grooves 117. The pulleys 118 on both sides of the first moving block 109 and the second moving block 108 roll along the moving grooves 117, converting the sliding friction between the first moving block 109 and the second moving block 108 and the moving grooves 117 into rolling friction, which greatly reduces the moving resistance. This allows the first clamping block 110 and the second clamping block 111 to move closer to or away from the workpiece more smoothly under the power drive. At the same time, the cooperation between the pulleys 118 and the moving grooves 117 forms a lateral limit on the first moving block 109 and the second moving block 108, preventing them from tilting or jamming during movement and ensuring clamping stability.
[0020] Furthermore, each of the opposite ends of the pair of first moving blocks 109 and the pair of second moving blocks 108 is provided with a connecting groove 115. A spring 114 is fixedly connected in the connecting groove 115. The other end of the spring 114 abuts against the two ends of the first sliding groove 106 and the second sliding groove 107 respectively. The springs 114 at the opposite ends of the first moving blocks 109 and the second moving blocks 108 are installed in the mounting groove 115. When the pneumatic telescopic rod 112 retracts, the spring 114 can provide a reverse elastic force to push the moving blocks to reset, causing the first clamping block 110 and the second clamping block 111 to automatically move away from the workpiece 2, so as to facilitate the quick removal of the workpiece.
[0021] Furthermore, the bottom end of the connecting seat 101 is provided with several connecting holes, and the top surface of the connecting seat 101 is provided with a baffle 104 at the position of the movable hole 105. The connecting seat 101 can withstand the vibration and impact force during four-axis machining and is not easily deformed after long-term use. The mounting hole at the bottom end makes it easy to fix the tooling on the air slip ring of the four-axis equipment to ensure overall stability during machining. The baffle 104 above the movable hole 105 can cover the movable hole 105 to prevent machining debris and coolant from entering the interior of the movable hole 105, thereby avoiding affecting the normal operation of the pneumatic telescopic rod 112 and the roller 113 and reducing maintenance costs.
[0022] Furthermore, dustproof blocks 120 are connected to the opposite ends of the first moving block 109 and the second moving block 108. Slots 119 are provided at both ends of the first slide 106 and the second slide 107. The dustproof blocks 120 are slidably connected to the slots 119. By slidably connecting the dustproof blocks 120 to the slots 119, one end of the first slide 106 and the second slide 107 can be protected to prevent waste from entering the interior of the first slide 106 and the second slide 107 during the movement of the first moving block 109 and the second moving block 108.
[0023] Working principle: In use, the tooling is first fixed to the air slip ring of the four-axis equipment through the mounting hole at the bottom of the connecting seat 101 to ensure overall stability. The air slip ring can stably provide an air source for the pneumatic telescopic rod 112. Then, the workpiece 2 is placed on the upper surface of the connecting seat 101, so that the outer side of the workpiece 2 initially fits against the first buffer pad on the inner side of the first abutment block 102 and the second abutment block 103, forming an initial outer limit. Next, the pneumatic telescopic rod 112 at the bottom of the movable hole 105 is activated. Its output end drives the four circumferentially arranged rollers 113 to rise synchronously. The rollers 113 roll into contact with the inclined surfaces of the wedge-shaped surfaces 116 at the opposite ends of the first moving block 109 and the second moving block 108, converting the longitudinal lift force into the lateral thrust force, pushing the first moving block 109 along the first slide groove 106 and the second moving block 108 along the second slide groove 107 to move towards the workpiece 2 synchronously. During this process, the pulleys 118 on both sides of the first moving block 109 and the second moving block 108 roll along the moving groove 117 to reduce the moving resistance. And prevent displacement; when the outer sides of the first clamping block 110 at the upper end of the first moving block 109 and the second clamping block 111 at the upper end of the second moving block 108 are closely attached to the workpiece 2, the workpiece 2 is firmly clamped by "outer abutment and inner clamping"; after processing, the pneumatic telescopic rod 112 retracts, the roller 113 descends, and the first moving block 109 and the second moving block 108 are reset under the reverse elastic force of the spring 114 in the opposite end mounting groove 115, which drives the first clamping block 110 and the second clamping block 111 away from the workpiece 2, so that the workpiece can be quickly removed; throughout the process, the baffle 104 above the movable hole 105 blocks the processing debris from entering the groove, protecting the pneumatic telescopic rod 112 and the roller 113 to operate normally. By sliding the dustproof block 120 to the slot 119, one end of the first slide groove 106 and the second slide groove 107 can be protected to prevent the debris from entering the first slide groove 106 and the second slide groove 107 during the movement of the first moving block 109 and the second moving block 108.
[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
