DETAILED DESCRIPTION

[0024] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments.

[0025] like Figure 1-Figure 2 As shown, the utility model provides a hot ring forging measuring tool, including an outer diameter measuring rod 1, the outer diameter measuring rod 1 includes a fixed rod 11, a movable rod 12, an outer measuring rod 13, and a hand screw 14, the fixed rod 11 is provided with an axial hole; a slideway penetrating the axial hole is provided along the fixed rod 11; the inner end of the movable rod 12 is slidably matched with the axial hole; the outer ends of the fixed rod 11 and the movable rod 12 are correspondingly provided with the outer measuring rod 13; a measuring ruler is provided along the movable rod 12; the scale of the measuring ruler corresponds to the measuring distance between the two outer measuring rods 13 on the fixed rod 11 and the movable rod 12; preferably, the fixed rod 11 and the movable rod 12 are vertically connected to the outer measuring rod 13; the outer measuring rods 13 on the fixed rod 11 and the movable rod 12 are coplanar and parallel.

[0026] The inner end of the movable rod 12 is connected to the bottom of the axial hole with a tension spring; relying on the elastic force of the tension spring, the movable rod 12 is retracted into the fixed rod 11, so that the fixed rod 11 and the outer measuring rod 13 on the movable rod 12 are close to each other.

[0027] like Figure 3 As shown, a hand screw 14 passes through a slideway and is threadedly connected to a screw hole on a movable rod 12; a clamping piece 2 is provided on the hand screw 14 for clamping the outer wall of the fixed rod 11; by rotating the hand screw 14, the clamping piece 2 can contact or separate from the outer wall of the fixed rod 11.

[0028] Preferably, the screw hole is located at the inner end of the movable rod 12, the diameter of the hand screw 14 is suitable for the width of the slideway, and the slideway constrains the hand screw 14 so that the hand screw 14 moves linearly along the slideway, so that the two outer measuring rods 13 always maintain a coplanar state.

[0029] The process of measuring the ring forging using the tool is as follows: first, operate the hand-tightened screw rod 14 to overcome the elastic force of the tension spring, drive the movable rod 12 to move outward along the shaft hole, so that the outer measuring rod 13 on the movable rod 12 and the fixed rod 11 is located outside the ring forging; because the rods of the movable rod 12 and the fixed rod 11 are relatively long, it is effectively prevented that the operator is burned by the high temperature of the hot ring during use;

[0030] Then, the outer measuring rod 13 on the fixed rod 11 is brought into contact with one end of the outer arc surface of the ring forging; then, the screw rod 14 is tightened by hand, and the movable rod 12 is driven to move in the opposite direction by the elastic force of the tension spring, so that the other end of the outer arc surface of the ring forging is brought into contact with the outer measuring rod 13 on the movable rod 12; the tension spring is conducive to the two outer measuring rods 13 being reliably close to the ring forging, avoiding unstable hand holding, resulting in erroneous movement of the movable rod 12, and causing inaccurate measurement values;

[0031] Finally, the hand-tightening screw 14 is rotated to make the clamping plate 2 close to the outer wall of the fixed rod 11, and the fixed rod 11 and the movable rod 12 are locked by friction. Preferably, the slide opening of the fixed rod 11 is provided with a flat surface, and the contact between the flat surface and the clamping plate 2 improves the locking effect; a pointer corresponding to a measuring ruler is provided at the outer end of the fixed rod 11; at this time, the outer diameter of the measured ring forging can be accurately obtained by the scale value of the measuring ruler corresponding to the pointer on the fixed rod 11.

[0032] The friction force of the clamping plate 2 contacting the fixed rod 11 can limit the axial displacement of the movable rod 12, which is convenient for fixing the position of the movable rod 12 during and after the measurement, and for accurate measurement and stable storage of the tooling.

[0033] like Figure 1As shown, the tooling also includes a support rod 3, the top of the support rod 3 is hinged to the lower side of the fixed rod 11, and the bottom of the support rod 3 supports the ground. Preferably, the support rod 3 and the fixed rod 11 adopt a detachable structure; specifically, the lower side of the fixed rod 11 is provided with an interlocking groove and a connector; usually, the support rod 3 is flat against the fixed rod 11 and stored in the interlocking groove, which is convenient to carry and occupies little space; when in use, the support rod 3 is removed, and the top of the support rod 3 is hinged to the connector; the bottom of the support rod 3 is supported on the ground or the equipment foundation, which greatly reduces the force on the workers when using the tooling and is convenient for measurement in a high temperature environment.

[0034] Preferably, the top of the support rod 3 is provided with a convex spherical surface, and the fixed rod 11 is provided with a concave spherical surface, and the convex spherical surface matches the concave spherical surface. By setting the support rod 3 and the fixed rod 11 to be spherically connected, the worker can flexibly adjust the direction of the fixed rod 11 and the movable rod 12 around the fulcrum of the support rod 3, which is conducive to avoidance and improves the measurement flexibility.

[0035] like Figure 1 , Figure 2 As shown, the tooling also includes a connecting seat 4 and an inner diameter measuring rod 5, one side of the connecting seat 4 is connected in parallel to a fixed rod 11 and a guide cylinder 6; the inner diameter measuring rod 5 includes a fixed rod 2 51, a hand screw 2 52, and an inner measuring rod 53; the inner end of the fixed rod 2 51 is slidably matched with the guide cylinder 6; the side wall of the guide cylinder 6 is provided with a guide channel 61 that is disconnected along the axial direction; the hand screw 2 52 passes through the guide channel 61 and is threadedly connected with the screw hole on the fixed rod 2 51; the hand screw 2 52 is provided with a clamping plate 2 for clamping the outer wall of the fixed rod 2 51; a measuring ruler is provided along the fixed rod 2 51; the outer end of the fixed rod 2 51 is provided with a first inner measuring rod 53, and the second inner measuring rod 53 is slidably connected with the fixed rod 2 51 through a sliding sleeve, and the sliding sleeve is connected to the fixed rod 2 51 through a hand locking member; the two inner measuring rods 53 are coplanar and parallel to the outer measuring rod 13. The hand-tightening locking member adopts the existing hand-tightening bolt, and the sliding sleeve is provided with a screw hole, which matches with the thread of the hand-tightening bolt. The inner end of the hand-tightening bolt is used to tighten the fixing rod 2 51, so that the sliding sleeve and the fixing rod 2 51 are fixed in position.

[0036] The inner measuring rod 53 is flush with the measuring end of the outer measuring rod 13; the measuring process of the inner diameter measuring rod 5 is as follows: operate the second hand screw 52 to drive the inner measuring rod 53 on the second fixed rod 51 to contact one end of the inner arc surface of the ring forging; operate the hand locking piece to drive the second inner measuring rod 53 to contact the other end of the inner arc surface of the ring forging, and lock the position by the hand locking piece; then, screw the second hand screw 52 to lock the axial movement of the second fixed rod 51, and then obtain the inner diameter size through the measuring ruler; the measuring principle of the inner diameter measuring rod 5 is the same as that of the outer diameter measuring rod 1; it will not be described in detail here;

[0037] The inner and outer diameters of the ring forging are measured respectively by the inner diameter measuring rod 5 and the outer diameter measuring rod 1, and the two sizes of the ring forging are measured in one operation, which improves the measurement efficiency and saves the process of adjusting the tooling when measuring the inner and outer diameters.

[0038] Preferably, a compression spring is provided between the two inner measuring rods 53. Relying on the elastic force of the compression spring, the two inner measuring rods 53 are kept away from each other, which is conducive to the inner measuring rods 53 reliably contacting the inner arc surface of the ring forging, and avoiding the displacement of the inner measuring rods 53 due to unstable hand holding when operating the hand-tightening screw rod 2 52, resulting in inaccurate measurement.

[0039] like Figure 5 As shown, the measuring ends of the outer measuring rod 13 and the inner measuring rod 53 are both plugged and connected with the measuring block 7. The measuring block 7 is made of high temperature resistant material. After the measuring block 7 is damaged due to multiple measurements, only the damaged measuring block 7 needs to be replaced to avoid the entire tooling being scrapped due to wear and tear.

[0040] like Figure 4 As shown, the inner measuring rod 53 is provided with a through hole 531, and the middle part of the movable rod 12 is slidably matched with the through hole 531. With this design, the movable rod 12 plays a supporting and guiding role for the inner measuring rod 53, thereby improving the stability of the inner and outer diameter measurement.
