Technical Field

[0001] The utility model relates to the technical field of roundness measuring instruments, and more specifically, the utility model relates to a clamping mechanism of a roundness measuring instrument. Background Technique

[0002] A roundness measuring instrument is a measuring instrument that measures the radial shape change of a measured part and makes evaluations and records according to the definition of roundness; it is usually used to measure the roundness, coaxiality, etc. of the inner and outer circles and spheres of a rotating body; when using a roundness measuring instrument, it is necessary to fix the object to be measured with a clamping mechanism.

[0003] For example, an ovality measuring instrument with a clamping mechanism disclosed in CN219573015U, the key points of its technical solution are: including a support plate, a fixed plate is arranged at the right side position of the top of the support plate, four sliders penetrate and are slidably connected through the front and rear ends of the top of the fixed plate, and fixing bolts penetrate and are threadedly connected through the top positions on the left and right sides of the four sliders and are threadedly connected between the fixing bolts and the fixed plate, clamping plates are fixedly connected to the top positions of the four sliders, connecting plates are fixedly connected to the middle positions of the front and rear ends of the two clamping plates, bolts penetrate and are slidably connected through the right side positions of the four connecting plates, a first motor is fixedly connected to the middle position on the left side of the support plate, a lead screw is fixedly connected to the output end of the first motor, a nut pair penetrates and is threadedly connected through the left side position of the outer diameter of the lead screw, a fixed block is fixedly connected to the top position of the nut pair, a cylinder is fixedly connected to the top position of the fixed block, a telescopic rod penetrates and is arranged at the bottom position of the cylinder, a measuring instrument body is fixedly connected to the bottom position of the telescopic rod, a second motor is fixedly connected to the right side position at the bottom of the support plate, and a rotating shaft is fixedly connected to the output end of the second motor and is fixedly connected to the fixed plate; it mainly clamps the workpiece by sliding the sliders in the fixed plate to make the two clamping plates approach each other, fixes the fixed plate and the sliders together with the fixing bolts, slides the bolts into the connecting plates, and then screws the nuts into the bolts to fix the workpiece to prevent the workpiece from shaking during measurement. The first motor drives the lead screw to rotate, the lead screw drives the nut pair and the fixed block to move to the right and approach the workpiece, and the cylinder drives the telescopic rod and the measuring instrument body to move downward to align the measuring point of the measuring instrument with the workpiece, so that workpieces with different heights and diameters can be measured, greatly improving the versatility of the device.

[0004] The above clamping mechanism of a roundness measuring instrument still has certain deficiencies: since the clamping mechanism is fixed on the upper surface of the roundness measuring instrument by multiple groups of bolts, once the clamping mechanism needs to be disassembled, the disassembly of multiple groups of bolts will increase the working time required.

On the left side of the upper surface of the main body 1 of the roundness measuring instrument, a rotating disk 5 is detachably installed. At the top of the rotating disk 5, a mounting disk 6 is fixedly connected. On the upper surface of the mounting disk 6, four connecting grooves 7 are arranged in a circular array. Inside the connecting groove 7, a fastening ring 8 is adhered. At the top of the mounting disk 6, a clamping component 9 is connected through the fastening ring 8;

[0025] The clamping component 9 includes a connecting ring 91, a support plate 92 and a connecting rod 93. On the surface of the connecting ring 91, four support plates 92 are fixedly connected in a circular array. At the bottom end of the support plate 92, a connecting rod 93 is fixedly connected. The bottom end of the connecting rod 93 is adapted to the inside of the fastening ring 8. Inside the connecting ring 91, four hydraulic telescopic rods 94 are detachably installed in a circular array. One end of the hydraulic telescopic rod 94 is fixedly connected with an arc-shaped mounting plate 95. On the side wall of the arc-shaped mounting plate 95, a protective pad 96 is adhered. The materials of the protective pad 96 and the fastening ring 8 are both rubber components. The lifting component 4 includes a stable base 41 and a limiting rod 42. At the center of the upper surface of the stable base 41, a limiting rod 42 is fixedly connected. The lower surface of the stable base 41 is connected to the other side of the upper surface of the main body 1 of the roundness measuring instrument. The surface of the limiting rod 42 is movably sleeved with a slider 43. On one side of the lower surface of the slider 43, two hydraulic lifting rods 44 are detachably installed symmetrically along the center. The bottom end of the hydraulic lifting rod 44 is connected to one side of the upper surface of the stable base 41. On the other side of the lower surface of the slider 43, a connecting block 45 is fixedly connected. At the bottom end of the connecting block 45, a measuring head 46 is detachably installed.

[0026] Beneficial effect: Through the setting of the lifting component 4, it is beneficial to adjust the height of the measuring head 46, thereby facilitating the measurement of the roundness of an object.

[0027] The working process of the present utility model is as follows:

[0028] When the clamping mechanism is in use, in order to reduce the use cost, a protective pad 96 is provided. When it is necessary to measure the roundness of an object, first place the object to be measured inside the clamping component 9, and then start the four groups of hydraulic telescopic rods 94 to drive the arc-shaped mounting plate 95 and the protective pad 96 to move until the side wall of the protective pad 96 is attached to the surface of the object to be measured. At this time, the object to be measured can be clamped. Because the material of the protective pad 96 is a rubber component, when clamping the object, the surface of the object will not be damaged, thereby reducing losses.

[0029] In the above solution, when the clamping mechanism is in use, in order to facilitate the disassembly of the clamping assembly 9, a connecting groove 7, a fastening ring 8 and a connecting rod 93 are provided. When it is necessary to disassemble the clamping assembly 9, at this time, only the connecting rod 93 needs to be pulled out from the inside of the fastening ring 8, and then the clamping assembly 9 can be disassembled. Since the connecting rod 93 is snap-connected inside the fastening ring 8 and can be directly pulled out, compared with other connection methods for connecting the clamping assembly 9 to the roundness measuring instrument, this connection method saves more time during disassembly.
