[0042] like Figures 1-11 As shown, this embodiment is achieved through the following technical solution: an indirect measuring frame 2 is provided on one side of the slide table 1, and a movable measuring carriage 4 for placing workpieces is provided on the slide table 1.

[0043] The slide table 1 is equipped with several dial indicator holders 3, each corresponding to a different measurement station. Each dial indicator holder 3 is equipped with a dial head 5 for measuring the workpiece. The measuring carriage 4 can move the workpiece between these measurement stations to complete the measurement of different parts of the workpiece. In this embodiment, the dial head 5 is a dial indicator, and a rotating workpiece 6 is placed on the measuring carriage 4. A thread sample block 7 for testing can be installed on the rotating workpiece 6. Figure 1 , Figure 11 As shown.

[0044] Specifically, a guide rail 102 is provided on the slide table 1; the measuring carriage 4 can move along the guide rail 102.

[0045] The slide table 1 is provided with a first baffle 103 for limiting the movement of the measuring vehicle 4; in this embodiment, two sets of first baffles 103 are disposed on the surface of the slide table 1, such as... Figure 1 As shown, the measuring vehicle 4 can move between the two first baffles 103.

[0046] The slide table 1 is also equipped with positioning bolts 101 for positioning the indirect measuring frame 2.

[0047] Specifically, the indirect measuring frame 2 includes a main support rod 201, a measuring fork 204 is hinged to the main support rod 201, and a measuring head 205 is provided on the measuring fork 204.

[0049] In this embodiment, the measuring fork 204 hangs naturally under the action of gravity, and the second baffle 202 is positioned below the hinge center of the measuring fork 204. Figure 2As shown, after the conventional measuring fork 204 is lowered, its tail abuts against the second baffle 202 to prevent the measuring fork 204 from drooping excessively; one end of the adjusting screw 203 can abut against one side of the measuring fork 204, and the drooping amplitude of the measuring fork 204 can be adjusted by rotating the adjusting screw 203, so that the measuring fork 204 can drive the measuring head 205 to finely adjust the measuring position.

[0050] The measuring fork 204 is U-shaped. In use, the main measuring rod 2042 and the measuring head 205 are inserted into the inner cavity of the rotating workpiece 6. After the measuring head 205 comes into contact with the measuring part, the measurement begins. The main measuring rod 2042 and the measuring head 205 move up and down with the rotation of the rotating workpiece 6. Synchronously, the auxiliary measuring rod 2041 also moves. The probe of the meter 5 is attached to the mark 2044 of the auxiliary measuring rod 2041. Thus, the measurement movement amplitude of the inner cavity of the rotating workpiece 6 is transmitted to the external meter 5 through the measuring fork 204. The measurement data can be read by manually observing the meter 5.

[0051] Specifically, the measuring fork 204 includes: a secondary measuring rod 2041 and a main measuring rod 2042 arranged in parallel.

[0053] The main support rod 201 can be snapped onto the slide table 1 via the snap-fit ​​base 2011; the main support rod 201 can be fixedly connected to the slide table 1 via the positioning bolt 101.

[0054] Specifically, the frame 3 includes: a vertical rod 302 connected to the slide table 1, and a clamping nut 301 is also fitted on the vertical rod 302. The vertical rod 302 can be fixedly connected to the slide table 1 by the clamping nut 301.

[0055] Multiple clamping assemblies, crossbars 306, and dial gauges 5 can be installed on the dial gauge frame 3. By adjusting the position and orientation of different crossbars 306 and dial gauges 5, multiple parts of the rotating workpiece 6 can be measured simultaneously.

[0056] The upright 302 is provided with a clamping assembly, which includes: an open sleeve 305 sleeved on the upright 302, a clamping screw 304 passing through the open sleeve 305, and a tightening nut 303 fitted on the clamping screw 304; an adapter tube 307 is provided at the end of the clamping screw 304 away from the tightening nut 303; and a crossbar 306 is inserted into the adapter tube 307.

[0057] A meter clamp 308 is provided on one end of the crossbar 306, and the meter 5 is set on the meter clamp 308.

[0058] Specifically, the measuring carriage 4 includes: a sliding seat 401 slidably connected to the slide table 1, a rotating shaft 403 hinged on the sliding seat 401, and a roller 402 hinged on the rotating shaft 403; the roller 402 is slidably connected to the table surface of the slide table 1.

[0059] The sliding seat 401 is provided with a rolling seat 404 and a fastening screw 407. The rolling seat 404 can be fixedly connected to the sliding seat 401 by the fastening screw 407. Figure 8 As shown; a roller 405 is hinged to the rolling seat 404, and the workpiece can abut against the roller 405 and rotate between the rollers 405.

[0060] In this embodiment, the rollers 405 on the sliding seat 401 are arranged in pairs, and the rollers 405 on a single sliding seat 401 are arranged in a V-shape. The rotating workpiece 6 is placed between the two rollers 405. Figure 8 , Figure 9 As shown.

[0061] A limiting plate 406 for limiting the workpiece is also provided on one side of the sliding seat 401.

[0062] Specifically, the bottom of the sliding seat 401 is provided with a sliding groove 4011, which can be slidably connected to the guide rail 102.

[0063] The bottom of the rolling seat 404 is provided with a positioning protrusion 4041, and the sliding seat 401 is provided with a positioning groove 4012; the positioning protrusion 4041 is fitted into the positioning groove 4012.

[0064] The specific working principle of this utility model is as follows:

[0065] During measurement, the rotating workpiece 6 is first positioned and placed on the measuring carriage 4 by a person. After positioning, the measuring carriage 4 is pushed to different measuring stations by a person, and the rotating workpiece 6 is rotated to complete the workpiece measurement. At the left station, the internal cavity form and position tolerance of the rotating workpiece 6 is measured by the indirect measuring frame 2, and the left end face of the rotating workpiece 6 is measured by multiple sets of dial indicators 5 set on the dial indicator frame 3. At the right station, the external surface and right end face of the rotating workpiece 6 are measured by multiple sets of dial indicators 3 and dial indicators 5. Thus, the rotating workpiece 6 can be measured in multiple parts in one clamping.
