Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a radial positioning device for the spindle of a roundness meter. Background Technique

[0002] A roundness meter is a length measuring tool that measures roundness using the rotary shaft method. Roundness meters are divided into two types: sensor rotary type and workbench rotary type, which can measure the roundness values of different workpieces. When clamping the workpiece, since only one end is clamped, it is easy for the workpiece to swing to a certain extent due to centrifugal force during rotation, resulting in inaccurate measurement results.

[0003] Chinese Patent No. CN221173349U provides a radial positioning device for the spindle of a roundness meter, including a main body mechanism, a detection mechanism, and a control mechanism. The detection mechanism is located at the left end of the main body mechanism, and the control mechanism is located at the left end of the main body mechanism. The main body mechanism includes a bearing base, and a rotating table is rotatably connected to the upper end of the bearing base. A rotating seat is rotatably connected to the upper end of the rotating table. By setting the structure of the rotating seat, the measuring structure can be placed on the rotating seat, and then the rotating seat is manually rotated. Due to the structure of the limiting part and the limiting bolt, the sliding crank will expand inwards or outwards on the rotating seat, and at the same time, the measuring structure will be closer to the center of the rotating seat and fixed. Then, the adjusting bolt can be adjusted to fix the measuring structure with the fixing block, so as to prevent the measuring structure from deviating during detection. At the same time, the rubber pad will protect the measuring mechanism and prevent damage.

[0004] For a radial positioning device for the spindle of a roundness meter in the prior art, there are the following problems: Although it can clamp the workpiece to be measured, for a relatively long workpiece to be measured, centrifugal force will occur during rotation, resulting in inaccurate measurement results.

[0005] Therefore, it is urgent to design a radial positioning device for the spindle of a roundness meter to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a radial positioning device for the spindle of a roundness meter is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A radial positioning device for the spindle of a roundness meter, comprising a control component. Inside the control component, there is a rotating component rotatably connected. On one side of the rotating component, there is a driving component fixed. On the top of the control component, there is a measuring component fixed. The driving component includes a support frame, which is fixed on one side of the rotating component. On one side of the support frame, there is a second motor fixed. At the end of the output shaft of the second motor, there is a first gear fixed. Inside the support frame, there is a rotating rod rotatably connected. On one side of the rotating rod, there is a crown gear fixed. The crown gear meshes with the first gear. At the end of the rotating rod, there is a first bevel gear fixed. On one side of the first bevel gear, there is a second bevel gear meshing. Inside the second bevel gear, there is a connecting rod fixed. At the end of the connecting rod, there is a second gear fixed.

[0009] Furthermore, the control component includes a base. On one side of the base, there is a control box fixed. On the top of the control box, there is a control handle arranged. At the bottom of the base, there are support legs fixed. On the top of the base, there is a first strong magnet fixed.

[0010] Furthermore, inside the base, there is a support ring rotatably connected. On one side of the support ring, there is a support plate rotatably connected. On the top of the support plate, there is a second strong magnet fixed.

[0011] Furthermore, the rotating component includes a first motor, which is fixed at the bottom of the base. At the end of the output shaft of the first motor, there is a rotating frame fixed. The support frame is fixed on one side of the rotating frame. Inside the rotating frame, there is a driving frame rotatably connected. The driving frame meshes with the second gear.

[0012] Furthermore, on the top of the driving frame, there is a clamping block threadedly connected. The clamping block is slidably connected inside the rotating frame. At the end of the clamping block, there is an anti-slip pad fixed.

[0013] Furthermore, the measuring component includes a measuring column, which is fixed on the top of the support plate. Inside the measuring column, there is a third motor fixed. At the end of the output shaft of the third motor, there is a lead screw fixed. On one side of the lead screw, there is a lifting block threadedly connected.

[0014] Furthermore, inside the lifting block, there is a fastening screw threadedly connected. Inside the lifting block, there is a sliding bar slidably connected. At the end of the sliding bar, there is a detector fixed.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By means of the driving component set, in the way that the second motor drives the first gear to rotate, the crown gear drives the first bevel gears at both ends to rotate through the rotating rod, so that the second bevel gear drives the gear to rotate through the connecting rod, and then the driving frame drives the clamping block to clamp the workpiece to be measured. Due to the setting of two groups of clamping blocks, when the workpiece to be measured rotates, the workpiece to be measured between the two groups of clamping blocks will not generate centrifugal force, so that the measurement result can be accurate.

[0017] 2. By means of the provided measuring component, and by using the way that the slider can slide within the lifting block, the position of the detector can be changed, so that the device can measure the roundness of the workpiece to be measured within a certain range.

[0018] 3. By means of the provided strong magnet one and strong magnet two, due to the mutual attraction of multiple groups of strong magnet one and strong magnet two, the support plate can be supported by the support ring, and the rotation can be restricted by strong magnet one and strong magnet two, so that the measuring component will not rotate following the support ring through the support plate.

[0019] 4. By means of the provided anti-slip pad, by using the certain elasticity and surface roughness of the anti-slip pad itself, when the clamping block clamps the workpiece to be measured, it is not easy to leave indentations, and it can also prevent slipping between the workpiece to be measured and the clamping block.

The first bevel gear 22 drives the second bevel gear 23 to rotate through meshing, and then the second gear 25 is driven to rotate by the connection of the connecting rod 24. When the second gear 25 rotates, it drives the driving frame 13 to rotate within the rotating frame 12, and then drives the clamping block 14 to move through the driving frame 13, so as to clamp the workpiece to be measured through the anti-slip pad 15. Then, by adjusting the sliding strip 32 to extend out of the lifting block 30, the detection part of the detector 33 is made to adhere to the workpiece to be measured. At this time, tighten the fastening wire 31, so that the sliding strip 32 is fixed. Then start the first motor 11, so that the rotating frame 12 drives the driving assembly 16 and the workpiece to be measured to rotate, thereby enabling the roundness measurement of the workpiece to be measured. If it is necessary to change the measurement position, the third motor 28 can be started, so that the lead screw 29 drives the lifting block 30 to move, thereby being able to change the position where the detector 33 is located.
