Abstract
Description
Technical Field
[0001] This application relates to the field of measuring instrument technology, specifically to an anti-vibration measuring base for automated unit processing components. Background Technology
[0002] Propellers are typically manufactured with high precision using CNC automated units, making them one of the types of parts manufactured using automated units.
[0003] When measuring a propeller, the hub is usually placed on a table, and a measuring tape is used to measure the hub and blades. When there is vibration, the propeller will shake due to the continuous vibration of the table. When the blades are touched, the propeller will rotate, which is not conducive to the measurement of propeller data.
[0004] Therefore, this application provides a vibration-proof measuring base for automated unit processing parts to solve the above problems. Utility Model Content
[0005] This application provides a vibration-proof measuring base for automated unit processing parts, aiming to solve the problems mentioned in the background art, such as the propeller hub being placed on a table for measuring the hub and blades. When vibration occurs, the propeller will shake continuously due to the continuous vibration of the table, and the propeller will rotate when the blades are touched, which is not conducive to the measurement of propeller data.
[0006] To achieve the above objectives, this application provides the following technical solution: a vibration-damping measuring base for automated unit processing parts, applied to propellers; To reduce vibration during propeller measurement: a mounting base is provided at the bottom of the propeller for mounting the propeller; a clamping assembly is provided inside the mounting base for positioning the propeller hub; a pressing member is provided at the top of the mounting base for pressing the propeller; a vibration damping pad is provided at the bottom of the mounting base for damping the vibration of the mounting base; and a limiting member is provided at the top of the mounting base for limiting the rotation of the propeller blades. The vibration isolation pads reduce vibration transmission to the mounting base. During propeller measurement, the propeller hub is inserted into the slot, and the bidirectional screw is rotated to drive the two moving rods to move towards each other, causing the symmetrically arranged grippers to move to both sides of the hub to clamp the propeller. Then, the adjusting screw is rotated to move the pressing block towards the top of the propeller, thus pressing the propeller and preventing it from moving when it collides with the mounting base. Multiple limiting members at the top of the mounting base restrict the unidirectional rotation of the propeller blades, preventing random shaking during measurement. When the mounting base is accidentally touched, the top of part of the push rod contacts the inclined outer wall of the propeller blades, and the spring pushes the push rod to restrict the rotation of the blades, thus preventing propeller vibration and facilitating the measurement work.
[0007] Preferably, to facilitate propeller installation: the top of the mounting base has a slot for inserting the propeller hub, the interior of the mounting base has a mounting cavity for installing the clamping assembly, the slot extends through the top of the mounting cavity, and the bottom of the mounting base is fixedly connected to the top of the vibration damping pad. By inserting the propeller hub into the slot, the horizontal movement of the propeller is restricted.
[0008] Preferably, to prevent the propeller from moving out of the slot: the clamping assembly includes jaws symmetrically arranged inside the mounting cavity for clamping both sides of the propeller hub, a moving rod fixedly connected to the outer wall of the jaws for moving the jaws, and a bidirectional screw inserted at the end of the moving rod away from the jaws for driving the moving rod to move. The symmetrically arranged jaws clamp both sides of the propeller hub, ensuring the stability of the propeller hub within the slot. Simultaneously, the friction between the jaws and the propeller hub reduces rotation caused by vibration.
[0009] Preferably, to facilitate control of the gripper's movement: the outer wall of the moving rod has a first threaded hole for threaded insertion of the bidirectional screw; one side of the inner wall of the mounting cavity has a circular hole for inserting the bidirectional screw; the outer wall of one end of the bidirectional screw is fitted with a bearing for restricting the movement of the bidirectional screw; and the other side of the inner wall of the mounting cavity has a mounting groove for mounting the bearing. By rotating the bidirectional screw, the moving rod moves horizontally, thereby controlling the gripper's gripping of the propeller hub.
[0010] Preferably, to limit the vertical movement of the propeller: a fixing frame for mounting the pressing member is fixedly connected to the outer wall of the mounting base. The outer wall of the fixing frame has a second threaded hole for inserting the pressing member. The pressing member includes a pressing block disposed between the mounting base and the fixing frame for pressing the top of the propeller, and an adjusting screw fixedly connected to the top of the pressing block for vertical displacement of the pressing block. By rotating the adjusting screw, the pressing block is displaced to the top of the propeller, thereby limiting the vertical movement of the propeller.
[0011] Preferably, to limit propeller rotation: the limiting components include a push rod disposed at the top of the mounting base for limiting propeller blade rotation, a fixing post fixedly connected to the top of the mounting base for mounting the push rod, a limiting plate fixedly connected to the bottom of the push rod for limiting push rod movement, and a spring disposed inside the fixing post for pushing the limiting plate. By staggering multiple limiting components at the top of the mounting base, the direction of propeller rotation is limited, and the spring, by pushing the push rod into contact with the blade, can reduce blade displacement caused by accidental vibration.
[0012] Preferably, the fixed column has a storage cavity inside for accommodating the spring, and the top of the inner wall of the storage cavity has an insertion hole for inserting the top rod.
[0013] This application utilizes the design of a mounting base, clamping assembly, pressing component, vibration damping pad, and limiting component. The vibration damping pad reduces the transmission of vibration to the mounting base. By rotating the bidirectional screw, the symmetrically arranged claws grip the propeller, and then the pressing block presses down on the propeller to prevent propeller movement when it collides with the mounting base. In the event of accidental contact with the mounting base, the top of part of the push rod contacts the inclined outer wall of the propeller blade, limiting the rotation of the blade and preventing propeller vibration, thus facilitating the measurement work of the propeller by the operator.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0017] This embodiment provides a vibration-resistant measuring base for automated unit processing parts, such as... Figure 1-6 As shown, the measuring base is applied to propeller 1; To reduce vibration during propeller 1 measurement: a mounting base 2 is provided at the bottom of propeller 1 for mounting propeller 1; a clamping assembly 3 is provided inside the mounting base 2 for positioning the propeller 1 hub; a pressing component 4 is provided at the top of the mounting base 2 for pressing propeller 1; a vibration isolation pad 6 is provided at the bottom of the mounting base 2 for damping vibration of the mounting base 2; and a limiting component 7 is provided at the top of the mounting base 2 for limiting the rotation of propeller 1 blades. Vibration is reduced to the mounting base 2 by using vibration isolation pads 6. When measuring propeller 1, the hub of propeller 1 is inserted into the slot. Then, the bidirectional screw 33 is rotated to drive the two moving rods 32 to move towards each other, so that the symmetrically arranged grippers 31 move to both sides of the hub to clamp propeller 1. Then, the adjusting screw 42 is rotated to move the pressing block 41 towards the top of propeller 1, thereby pressing propeller 1 and preventing propeller 1 from moving when it collides with the mounting base 2. Multiple limiting parts 7 set at the top of the mounting base 2 can limit the unidirectional rotation of the propeller blades, thereby avoiding random shaking of propeller 1 during measurement. When the mounting base 2 is accidentally touched, the top of part of the push rod 71 contacts the inclined outer wall of the propeller blades. The spring 74 pushes the push rod 71 to limit the rotation of the blades, thereby preventing the vibration of propeller 1 and facilitating the measurement operation of propeller 1.
[0018] Specifically, to facilitate the installation of propeller 1: the top of the mounting base 2 has a slot for inserting the propeller hub 1, and the interior of the mounting base 2 has a mounting cavity for installing the clamping assembly 3. The slot passes through the top of the mounting cavity, and the bottom of the mounting base 2 is fixedly connected to the top of the vibration isolation pad 6. By inserting the propeller hub 1 into the slot, the horizontal movement of propeller 1 is restricted. The slot size is adapted to the hub size. Four vibration isolation pads 6 are provided, located at the four corners of the bottom of the mounting base 2. The mounting base 2 and the vibration isolation pads 6 are bonded and fixed at the contact points. The vibration isolation pads 6 are made of damping material, such as damping pads or foam, which consumes vibration energy through internal friction of the material, suppresses resonance, and thus plays a role in vibration isolation for the mounting base 2.
[0019] Specifically, to prevent the propeller 1 from moving out of the slot: the clamping assembly 3 includes symmetrically arranged jaws 31 inside the mounting cavity for clamping both sides of the propeller hub, a moving rod 32 fixedly connected to the outer wall of the jaws 31 for moving the jaws 31, and a bidirectional screw 33 inserted at the end of the moving rod 32 away from the jaws 31 for driving the moving rod 32 to move. The symmetrically arranged jaws 31 clamp both sides of the propeller hub, ensuring the stability of the propeller hub within the slot. Simultaneously, the friction between the jaws 31 and the propeller hub reduces rotation caused by vibration. The jaws 31 have a triangular opening facing the propeller 1, and the contact points between the jaws 31 and the moving rod 32 are bonded and fixed.
[0020] More specifically, to facilitate control of the movement of the gripper 31: the outer wall of the moving rod 32 has a first threaded hole for threaded insertion of the bidirectional screw 33, one side of the inner wall of the mounting cavity has a round hole for insertion of the bidirectional screw 33, one end of the outer wall of the bidirectional screw 33 is fitted with a bearing 34 to restrict the movement of the bidirectional screw 33, and the other side of the inner wall of the mounting cavity has a mounting groove for mounting the bearing 34. By rotating the bidirectional screw 33, the moving rod 32 moves horizontally, thereby controlling the gripper 31 to grasp the propeller hub. The inner thread of the first threaded hole meshes with the outer thread of the bidirectional screw 33, the round hole has a smooth inner wall that matches the size of the bidirectional screw 33, the bearing 34 is a ball bearing, and the size of the mounting groove matches the size of the bearing 34. The bearing 34 restricts the bidirectional screw 33 to rotate only, thereby controlling the symmetrically arranged grippers 31 to move towards or away from each other by rotating the bidirectional screw 33.
[0021] Specifically, to limit the vertical movement of the propeller 1: a mounting bracket 5 for mounting the pressing component 4 is fixedly connected to the outer wall of the mounting base 2. The outer wall of the mounting bracket 5 has a second threaded hole for inserting the pressing component 4. The pressing component 4 includes a pressing block 41 disposed between the mounting base 2 and the mounting bracket 5 for pressing the top of the propeller 1, and an adjusting screw 42 fixedly connected to the top of the pressing block 41 for vertical displacement of the pressing block 41. By rotating the adjusting screw 42, the pressing block 41 is moved to the top of the propeller 1, thereby limiting the vertical movement of the propeller 1. The inner thread of the second threaded hole meshes with the outer thread of the adjusting screw 42. The pressing block 41 and the adjusting screw 42 are welded and fixed at their contact points. The size of the pressing block 41 is larger than that of the propeller hub. The vertical cross-section of the fixing frame 5 is shaped like a "7". The fixing frame 5 is welded and fixed at its contact point with the mounting base 2. By rotating the adjusting screw 42, the pressing block 41 is lowered to the top of the propeller 1, thereby pressing down on the propeller 1 and preventing vertical displacement of the propeller 1.
[0022] Specifically, to limit the rotation of propeller 1, the limiting components 7 include a push rod 71 disposed at the top of the mounting base 2 to limit the rotation of the propeller blades 1, a fixing post 72 fixedly connected to the top of the mounting base 2 for mounting the push rod 71, a limiting plate 73 fixedly connected to the bottom of the push rod 71 to limit the movement of the push rod 71, and a spring 74 disposed inside the fixing post 72 to push the limiting plate 73. The fixing post 72 has a cavity for housing the spring 74, and the top of the inner wall of the cavity has a hole for inserting the push rod 71. By staggering multiple limiting components 7 at the top of the mounting base 2, the direction of propeller 1 rotation is limited. Simultaneously, the spring 74, by pushing the push rod 71 into contact with the blades, reduces blade displacement caused by accidental vibrations. Multiple limiting components 7 are arranged in a ring, with the positions of the limiting components 7 between different rings interlacing. The fixing post 72 is welded and fixed to the contact part of the mounting base 2. The storage cavity is cylindrical, with a diameter corresponding to the diameter of the limiting plate 73. The insertion hole is circular, corresponding to the diameter of the top rod 71. The contact part of the top rod 71 and the limiting plate 73 is welded. The spring 74 is always in a compressed state in the storage cavity. The size of the limiting plate 73 is larger than the size of the insertion hole, thereby preventing the top rod 71 from separating from the fixing post 72. When the propeller 1 is placed on the top of the mounting base 2, because the blade usually has an inclined surface, the blade at the lower position will be blocked by the top rod 71, thereby limiting the blade from continuing to rotate. The remaining parts of the top rod 71 will be pushed by the spring 74, so that the top of the top rod 71 contacts the side of the blade facing the mounting base 2, thereby pushing the blade vertically upward through the top rod 71. At the same time, there is friction at the contact part of the top rod 71 and the blade. Therefore, when slight vibration occurs, the rotation of the blade can be limited by the action of part of the top rod 71.
[0023] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
