Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically a tooling for checking misalignment data during workpiece assembly in machining. Background Technology

[0002] In the machining process of the machinery manufacturing industry, a large number of products, such as modular products like shells, covers, and housings, require assembly; and some critical parts requiring high precision, such as seals and bearings, need to be assembled together for overall processing. Inevitably, misalignment during assembly can occur. Figure 1 The workpiece shown has misalignment issues: radial misalignment between the surfaces of the inner diameter of the ring and axial misalignment between the sides of the inner diameter of the ring. When this happens, the holes and surfaces that were previously machined in the upper and lower parts should be aligned first. That is, the radial and axial alignment of the workpiece should be done first, and then the pin holes and screw holes for assembly should be machined to ensure the accuracy of the assembly.

[0003] Currently, when aligning these holes and surfaces, misalignment as described above often occurs. Existing misalignment inspection tools require a high level of skill from operators. During misalignment inspection, inaccurate measurement results often occur due to operational errors, making it difficult to achieve the radial and axial misalignment accuracy required by the process documents. This makes it difficult to guarantee the relevant quality requirements for subsequent assembly and processing. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for checking misalignment data during workpiece assembly in machining, which can detect axial and radial misalignment of workpieces with higher precision.

[0005] The technical solution of this utility model is:

[0006] A tooling for checking misalignment data during workpiece assembly in machining includes: a lever gauge with a connecting rod connected to one side of its housing; a handle, a plate structure with one side for contacting the side of the workpiece, and a mounting hole along the thickness direction near the top of the plate; two through holes along the thickness direction on the handle, the two through holes being at the same height and symmetrically arranged; and a clamping component including: two clamping heads, respectively disposed on both sides of the handle through the mounting hole, for clamping the connecting rod on the lever gauge housing; and two rolling columns, respectively rotatably disposed in the corresponding through holes, with at least one end extending out of the through hole for contacting the inner side of the workpiece hole.

[0007] Furthermore, each clamping head of the clamping member has a clamping hole near the top and a bolt hole near the bottom. The clamping hole is used to clamp the connecting rod, and a slot extending to the bolt hole is formed at the bottom of the clamping hole and extends to the bottom surface of the clamping head. The clamping member also includes a bolt and a nut that matches the bolt. The bolt is inserted into the mounting hole through the bolt holes of the two clamping heads.

[0008] Furthermore, a magnet is embedded on the side plate of the handheld part that contacts the side of the workpiece.

[0009] Furthermore, one of the rolling columns is provided with a cap, the inner wall of which is rotatably connected to the outer side of the rolling column, and one end of the cap is connected to the side plate of the handle away from the workpiece.

[0010] Furthermore, the mounting hole is a square slot, and the two ends of the slot are configured with arc-shaped surfaces for matching bolts.

[0011] Furthermore, a connecting hole is opened at the center of the handheld part. The connecting hole is used to connect an extension rod. The connecting hole is a threaded hole. One end of the extension rod is threaded and threadedly connected to the connecting hole.

[0012] Furthermore, one end of the bolt is provided with a rotating wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The two clamping heads of this utility model are located on both sides of the hand-held part. By installing a lever gauge on the clamping heads on different surfaces of the hand-held part, when the detection head of the lever gauge is located on the clamping head of the contact surface of the hand-held part, it is used to detect the radial misalignment of the inner diameter surface of the ring; when the detection head of the lever gauge is located on the clamping head of the hand-held part away from the contact surface, it is used to detect the axial misalignment of the side of the workpiece. By the rolling of the rolling column on the inner diameter surface of the ring, it is ensured that the movement trajectory of the hand-held part is concentric with the inner diameter of the ring, thereby ensuring the accuracy of the detected misalignment data.

[0015] 2. This utility model makes it more convenient to install and change the clamping head of the lever gauge at different positions by using the clamping method of bolts and nuts.

[0016] 3. This utility model prevents the handpiece from separating from the side of the workpiece when it moves by setting a magnet on the contact surface of the handpiece, thereby ensuring that the center of the movement trajectory of the handpiece is always consistent with the center of the inner diameter of the workpiece, thus ensuring the accuracy of the detection of misalignment data.

[0027] Example

[0028] like Figure 2As shown, a tooling for checking misalignment data during workpiece assembly in machining includes: a lever gauge 1, a handheld part 3, a clamping part 4, and two rolling columns 7. A connecting rod 2 is connected to one side of the housing of the lever gauge 1. It is worth noting that the lever gauge 1 is a conventional lever gauge, which is commercially available. In this embodiment, the connecting column 2 is connected to the housing of the lever gauge 1 by welding. The handheld part 3 is a plate structure made of metal material, with one side for adhering to the workpiece; this side is referred to as the contact surface. Figure 2 and Figure 3 As shown, mounting holes 5 are provided along the thickness direction near the top of the plate. Preferably, there are two mounting holes 5, which are symmetrically arranged. Two through holes 6 are provided along the thickness direction on the handle 3. The two through holes 6 are at the same height on the handle 3 and are symmetrically arranged. Figure 4 As shown, the clamping member 4 includes: two clamping heads 42, which are respectively disposed on both sides of the hand-held part 3 through the mounting holes 5, for clamping the connecting rod 2 on the housing of the lever gauge 1; and two rolling columns 7, which are respectively rotatably disposed in the corresponding through holes 6, and at least one end of which extends out from the through hole 6 for contacting the inner side of the workpiece.

[0029] like Figure 5 As shown, when measuring radial misalignment, lever gauge 1 is fixed to clamping head 42 located on one side of the contact surface via connecting rod 2, and the angle of clamping head 42 is adjusted to adjust the angle of lever gauge 1. First, the detection head of lever gauge 1 contacts the inner diameter of the workpiece, so that the contact surface is close to the side of the workpiece. Then, the hand-held part 3 is pressed down so that the rolling column 7 is only in contact with the inner diameter of the ring. The hand-held part 3 is moved along the inner diameter of the ring so that the rolling column 7 rolls on the inner diameter of the ring to ensure that the movement trajectory is concentric with the inner diameter of the workpiece. Thus, when the detection head of lever gauge 1 passes through the misalignment, the misalignment data is displayed on the test table of lever gauge 1.

[0030] like Figure 6 and Figure 7 As shown, when measuring axial misalignment, lever gauge 1 is fixed to clamping head 42 on the side away from the contact surface via connecting rod 2, and the angle of clamping head 42 is adjusted to adjust the angle of lever gauge 1. First, the contact surface is made to fit tightly against the side of the workpiece. Due to the thickness of the handheld part 3, the detection head of lever gauge 1 contacts the side of the workpiece, pressing the handheld part 3 so that the rolling column 7 only fits the inner diameter of the ring. The handheld part 3 is moved along the inner diameter of the ring so that the rolling column 7 rolls on the inner diameter of the ring to ensure that the movement trajectory is concentric with the inner diameter of the ring of the workpiece. When the detection head of lever gauge 1 passes through the misalignment on the side of the workpiece, the misalignment data is displayed on the detection gauge of lever gauge 1.

[0031] like Figure 4As shown, each clamping head 42 of the clamping member 4 has a clamping hole 421 near the top and a bolt hole near the bottom. The clamping hole 421 is used to clamp the connecting rod 2. The connecting rod 2 matches the size of the clamping hole 421. The bottom of the clamping hole 421 has a slot that extends to the bolt hole and extends to the bottom surface of the clamping head 42. The clamping member 4 also includes a bolt 41 and a matching nut. The bolt 41 is inserted into the mounting hole 5 through the bolt holes of the two clamping heads 42. By tightening the bolt 41, the slot is closed and the inner diameter of the clamping hole 421 is reduced, thereby clamping the connecting rod 2.

[0032] In some embodiments, such as Figure 2 As shown, a magnet 8 is embedded on the side plate of the hand-held part 3 that contacts the side of the workpiece. The magnet 8 can attract the hand-held part 3 to the side of the workpiece, preventing the hand-held part 3 from separating and misaligning from the side of the workpiece when it moves.

[0033] In some embodiments, such as Figure 3 As shown, one of the rolling columns 7 is provided with a cap 71. The inner wall of the cap 71 is rotatably connected to the outer side of the rolling column 7, and one end of the cap 71 is connected to the side plate of the hand-held part 3 away from the workpiece. During operation, the hand can be placed on the cap 71, which is convenient for operation and does not affect the rolling of the rolling column 7 on the annular inner diameter surface.

[0034] like Figure 2 As shown, the mounting hole 5 is a square slot, and the two ends of the slot are configured with arc-shaped surfaces for matching bolt 41. Bolt 41 can slide on the horizontal section of the square slot. The distance between the detection head of the lever table 1 and the workpiece to be measured has been adjusted, making it easier for the operator to align the detection head with the side of the belt.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, a connecting hole 9 is opened at the center of the handheld part 3. The connecting hole 9 is used to connect an extension rod. The connecting hole 9 is a threaded hole. One end of the extension rod is threaded and connected to the connecting hole 9. In some working conditions, it is difficult to detect the misalignment of the workpiece at close range. By connecting the extension rod to the connecting hole 9, the inspector can operate the handheld part 3 and the lever gauge 1 to detect the workpiece from a certain distance.

[0036] like Figure 4 As shown, a rotating wheel is provided at one end of the bolt 41 to facilitate rotation of the bolt 41.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
