Description

Technical Field

[0001] This utility model relates to the field of measuring table technology, specifically to a rotatable workpiece measuring table for machining. Background Technology

[0002] In the field of machining, measuring the dimensions of a workpiece often requires the use of a workpiece measuring table in conjunction with a measuring instrument. Existing workpiece measuring tables for machining typically consist of a basic mounting frame and measuring instruments slidably mounted on the frame. During use, the operator must manually adjust the positions of two or more measuring instruments to bring the measuring ends of the instruments into contact with the workpiece to be measured, thereby obtaining the workpiece's dimensional data. For workpiece clamping, manual tightening of bolts or simple clamps is often used. After placing the workpiece on the measuring table, the clamps or bolts are manually operated to clamp and position it. When measuring different angles or circumferential positions of the workpiece, the workpiece must first be loosened, manually rotated or adjusted to the target angle, and then re-clamped before measurement.

[0003] However, existing technologies have significant shortcomings. First, regarding the adjustment of the measuring instruments, the manual operation of each instrument individually is cumbersome and time-consuming. It also makes it difficult to ensure the synchronization of movement among multiple measuring instruments, leading to inconsistent measurement data due to adjustment errors, thus affecting measurement accuracy and reducing efficiency. Second, in the workpiece clamping process, manual clamping is inconvenient, and the clamping force is difficult to control precisely. Insufficient force can cause workpiece displacement during measurement, affecting the results, while excessive force may cause crushing damage to the workpiece surface, failing to balance clamping stability and workpiece integrity. Finally, when measuring workpieces at multiple angles, the frequent manual loosening, adjustment, and re-fixing of the workpiece not only increases the operator's workload and reduces measurement efficiency but also makes it difficult to guarantee the accuracy of the workpiece position after each adjustment. Human error can easily lead to deviations in measurement data at different angles, failing to meet the requirements for accurate measurement of multiple positions along the circumference of the workpiece. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a rotatable workpiece measuring table for machining, so as to solve the problems of cumbersome adjustment of the measuring device, unstable workpiece clamping, and inconvenience of multi-angle measurement in existing measuring tables.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a rotatable workpiece measuring table for machining, including a first mounting frame, a second mounting frame, a first measuring device, and a second measuring device. The first mounting frame and the second mounting frame are fixedly connected by bolts. The first measuring device and the second measuring device are slidably installed between the first mounting frame and the second mounting frame. It also includes a synchronous measuring component and a rotary clamping component. The synchronous measuring component is used to control the first measuring device and the second measuring device to move synchronously to measure the workpiece. The rotary clamping component is used to drive the workpiece to rotate, which facilitates the measurement of the workpiece.

[0006] More preferably, the synchronous measurement assembly includes a first worm gear, a first worm, a first rotating rod, a second rotating rod, a second worm, and a third mounting frame. The first and second measuring instruments are both threadedly connected to the first worm gear. The first and second worms are rotatably connected between the first and second mounting frames. The first worm gear on the first measuring instrument meshes with the first worm, and the first worm gear on the second measuring instrument meshes with the second worm. The symmetrically arranged first rotating rods are rotatably connected to the second mounting frame, and the second rotating rods are rotatably connected to the second mounting frame. The symmetrically arranged second rotating rods are driven by each other through a bevel gear set, and the symmetrically arranged first rotating rods are driven by each corresponding first and second worm through a bevel gear set. The symmetrically arranged third mounting frame is bolted to the side of the second mounting frame, and the first rotating rod is located within the corresponding third mounting frame.

[0007] More preferably, the first mounting frame and the second mounting frame limit the left and right sides of the first worm gear, so that the first worm gear will not move along with the first measuring device and the second measuring device when they move towards each other or away from each other.

[0008] More preferably, the rotary clamping assembly includes a placement tray, a third worm gear, a mounting base, a second worm wheel, clamping members, a pull rod, and a spring. The mounting base is rotatably connected between the first mounting frame and the second mounting frame. The placement tray is slidably connected inside the mounting base. The third worm gear is rotatably connected between the first mounting frame and the second mounting frame. The second worm wheel is keyed to the mounting base and meshes with the third worm gear. The symmetrically arranged clamping members are slidably connected inside the placement tray via the pull rod. A spring connects the outer side of the clamping member to the inner side of the placement tray, and the spring is sleeved on the corresponding pull rod.

[0009] More preferably, rubber pads are adhered to both sides of the clamping components facing each other.

[0010] More preferably, it also includes counterweights, which are symmetrically arranged and placed between the first and second mounting frames.

[0011] Compared with the prior art, the advantages of this utility model are: This utility model realizes synchronous movement measurement of the measuring instrument. With the transmission cooperation of the worm, worm wheel and bevel gear set in the synchronous measurement component, rotating the first worm can drive the first worm and the second worm to rotate synchronously. Then, through the threaded connection between the worm wheel and the measuring instrument, it is transformed into the synchronous movement of the first measuring instrument and the second measuring instrument in opposite directions or in opposite directions. There is no need to adjust the two measuring instruments separately, reducing operation steps, improving measurement efficiency, and ensuring the consistency and accuracy of measurement data.

[0012] It has a stable workpiece clamping function. By pulling the clamping component with the pull rod and cooperating with the elastic restoring force of the spring, the clamping component can automatically clamp the workpiece. At the same time, the rubber pads bonded to the opposite side of the clamping component can not only prevent the workpiece from shifting during the measurement process, but also prevent excessive clamping force from damaging the workpiece surface, thus ensuring the stability and integrity of the workpiece during measurement.

[0013] It supports multi-angle measurement of workpieces. Through the meshing transmission between the third worm and the second worm wheel in the rotating clamping assembly, rotating the third worm can drive the mounting base, the placement plate and the clamped workpiece to rotate together. Without the need for manual adjustment of the workpiece position, it can conveniently realize the measurement of different positions in the circumference of the workpiece, reduce the difficulty of manual operation, and can accurately control the rotation angle of the workpiece, further improving the accuracy of the measurement position.

[0024] Example: As shown in the attached figure, a rotatable workpiece measuring table for machining includes a first mounting frame 1, a second mounting frame 2, a first measuring device 3, and a second measuring device 5. The first mounting frame 1 and the second mounting frame 2 are fixed together by bolts. The first measuring device 3 and the second measuring device 5 are slidably mounted between the first mounting frame 1 and the second mounting frame 2. The first measuring device 3 and the second measuring device 5 cooperate to measure the workpiece. It also includes a synchronous measuring component and a rotary clamping component. The synchronous measuring component is used to control the first measuring device 3 and the second measuring device 5 to move synchronously to measure the workpiece. The rotary clamping component is used to drive the workpiece to rotate, which facilitates the measurement of the workpiece.

[0025] In this embodiment, specifically, the synchronous measurement component includes a first worm gear 4, a first worm 6, a first rotating rod 7, a second rotating rod 8, a second worm 9, and a third mounting frame 10. The first measuring device 3 and the second measuring device 5 are both threadedly connected to the first worm gear 4. The first mounting frame 1 and the second mounting frame 2 limit the left and right movement of the first worm gear 4. When the first measuring device 3 and the second measuring device 5 move towards or away from each other, the first worm gear 4 will not move with them. The first worm 6 and the second worm 9 are both rotatably connected between the first mounting frame 1 and the second mounting frame 2. The first worm gear 4 on the first measuring device 3 meshes with the first worm 6, and the first worm gear 4 on the second measuring device 5 meshes with the second worm 9. The symmetrically arranged first rotating rods 7 are rotatably connected to the second mounting frame 2, and the second rotating rods 8 are rotatably connected to the second mounting frame 2. The second rotating rods 8 are all connected to each other via bevel gear sets. The first rotating rods 7, which are symmetrically arranged, are all connected to the corresponding first worm 6 and second worm 9 via bevel gear sets. When the first worm 6 is rotated, it drives the first rotating rod 7 to rotate via the bevel gear set, which in turn drives the second rotating rod 8 to rotate. The second rotating rod 8 drives the first rotating rod 7 on the other side to rotate via the bevel gear set, and then drives the second worm 9 to rotate via the bevel gear set. This allows the second worm 9 and the first worm 6 to rotate synchronously, which in turn drives the first worm wheel 4 to rotate, causing the first measuring device 3 and the second measuring device 5 to move towards and away from each other. The symmetrically arranged third mounting frames 10 are fixed to the side of the second mounting frame 2 by bolts. The first rotating rod 7 is located in the corresponding third mounting frame 10 to protect the first transmission rod 7. Furthermore, the rotary clamping assembly includes a placement tray 11, a third worm gear 12, a mounting base 13, a second worm wheel 14, clamping members 15, a pull rod 16, and a spring 17. The mounting base 13 is rotatably connected between the first mounting frame 1 and the second mounting frame 2. The placement tray 11 is slidably connected inside the mounting base 13. The third worm gear 12 is rotatably connected between the first mounting frame 1 and the second mounting frame 2. The second worm wheel 14 is keyed to the mounting base 13 and meshes with the third worm gear 12. The symmetrically arranged clamping members 15 are slidably connected inside the placement tray 11 through the pull rod 16. Rubber pads are glued to opposite sides of the clamping members 15 for clamping the workpiece. A spring 17 is connected between the outer side of the clamping member 15 and the inner side of the placement tray 11. The spring 17 is sleeved on the corresponding pull rod 16. Furthermore, it also includes a counterweight 18, which is symmetrically arranged between the first mounting frame 1 and the second mounting frame 2. The counterweight 18 is used to increase the weight of the entire measuring platform, thereby improving the measurement stability.

[0026] When using this rotatable workpiece measuring table for machining, first pull the symmetrically arranged clamping members 15 outward by pulling the pull rod 16. At this time, the spring 17 is compressed. Place the workpiece to be measured on the placement tray 11. After releasing the pull rod 16, the spring 17 pushes the clamping members 15 to move towards each other under the action of elastic restoring force. The rubber pads bonded to the opposite side of the clamping members 15 stably clamp the workpiece, preventing the workpiece from shifting during the measurement process. At the same time, the rubber pads can also prevent excessive clamping force from damaging the surface of the workpiece. When the synchronous measurement assembly is started, the first worm 6 is rotated. The first worm 6 drives the corresponding first rotating rod 7 to rotate through the bevel gear set. The first rotating rod 7 drives the second rotating rod 8 to rotate through the bevel gear set. The second rotating rod 8 then drives the first rotating rod 7 on the other side to rotate through the bevel gear set. In turn, the second worm 9 rotates synchronously through the bevel gear set. Since the first mounting frame 1 and the second mounting frame 2 limit the left and right movement of the first worm wheel 4, the first worm wheel 4 will not move with the first measuring device 3 and the second measuring device 5. The rotating first worm 6 and the second worm 9 drive the first worm wheel 4, which meshes with them, to rotate. Through the threaded connection between the first worm wheel 4 and the first measuring device 3 and the second measuring device 5, the rotational motion of the first worm wheel 4 is converted into the linear motion of the first measuring device 3 and the second measuring device 5, so that the two can move synchronously in opposite directions. This allows for quick and accurate measurement of the relevant dimensions of the workpiece, reducing the cumbersome operation caused by adjusting the two measuring devices separately and improving measurement efficiency. When it is necessary to measure the dimensions of the workpiece at different angles, the third worm gear 12 is rotated, which drives the meshing second worm wheel 14 to rotate. The second worm wheel 14 drives the mounting base 13 to rotate via a key connection. The mounting base 13 drives the placement plate 11 and the workpiece fixed by the clamping part 15 to rotate together. Measurement of different circumferential positions of the workpiece can be achieved without manual adjustment of the workpiece position, making operation more convenient and ensuring the accuracy of the measurement position. The first rotating rod 7 is located inside the third mounting frame 10. The third mounting frame 10 protects the first rotating rod 7 and the related bevel gear set, preventing dust and impurities from affecting the transmission effect and extending the service life of the components. The symmetrically arranged counterweights 18 placed between the first mounting frame 1 and the second mounting frame 2 increase the weight of the entire measuring table, effectively improving the stability during the measurement process, reducing the shaking caused by the movement of the measuring instrument or the rotation of the workpiece, and thus improving the accuracy of the measurement data. The entire measurement process achieves synchronized operation of the two measuring instruments through the synchronous measurement component, and stable clamping and flexible rotation of the workpiece through the rotary clamping component. The coordinated work of each component simplifies the operation process and ensures the accuracy and efficiency of the measurement, making it suitable for various measurement scenarios of machined workpieces.

This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
