Description

Technical Field

[0001] This invention belongs to the technical field of locomotive measurement tooling equipment, specifically relating to a tooling and method for rapid measurement of the meshing amount of a lead screw welded assembly. Background Technology

[0002] The brake caliper lead screw assembly is a key component for brake release. During the production or maintenance of the brake caliper lead screw weld assembly, the meshing amount of the V-shaped teeth in the weld assembly needs to be measured to ensure the accuracy of the lead screw during use. Due to the large number of welded components, existing measurement methods require multiple clamping and measurement operations, resulting in low efficiency.

[0003] Therefore, there is an urgent need for a tooling and method for rapid measurement of the meshing amount of a welded screw assembly that is simple in structure, low in cost, can be assembled from multiple screws at one time, is highly flexible, easy to clamp, rapid in measurement, convenient in use and maintenance, reduces the workload and labor intensity of measurement, and improves work efficiency. This is a problem that needs to be solved. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, this invention proposes a tooling and method for rapid measurement of the meshing amount of welded lead screw components. The tooling is ingeniously designed, simple in structure, low in cost, and convenient to use and maintain. It can clamp multiple welded lead screw components at once, offering high flexibility, simple clamping, rapid measurement, and convenient use and maintenance. This reduces the workload and labor intensity of measurement, improving work efficiency and enterprise benefits.

[0005] The technical solution of this invention is: a tooling for rapid measurement of the meshing amount of a lead screw welded assembly, comprising a circular platform, a rotating mechanism, and a measuring mechanism. The circular platform is disposed at the bottom of the rotating mechanism, and the measuring mechanism is disposed at the top of the rotating mechanism. The measuring mechanism includes a square base, a lower toothed sleeve, an upper toothed sleeve, a guide rod, a limiter, a toothed ring positioning shaft, a positioning sleeve, a positioning pin, a gauge plate, a locking nut, and a screw. The guide rod is fixedly disposed on the square base, and a lower toothed sleeve that meshes with the lead screw is disposed on one side of the guide rod. The positioning sleeve is disposed on the guide rod, and a limiter is disposed at the lower end of the positioning sleeve. A positioning pin is installed on the side wall of the limiter, and the positioning pin is inserted into a reserved hole on the guide rod to fix the limiter. A locking nut is disposed at the upper end of the positioning sleeve, and the positioning sleeve is locked and fixed by tightening the locking nut. One end of the positioning sleeve gradually decreases outward to form a tapered part, and an upper toothed sleeve that is positioned opposite to and matches the lower toothed sleeve is disposed at the lower end of the tapered part.

[0006] As a further optimization of the aforementioned tooling for rapid measurement of the meshing amount of a lead screw welded assembly, the rotating mechanism includes a rotating shaft located at the center of a circular platform. Three support frames are evenly arranged outward in the horizontal direction on the rotating shaft. A cylinder is provided at the far end of each support frame. A support rod is fitted inside the cylinder. A wheel that travels on the circular platform is provided at the bottom of the support rod. A measuring mechanism is provided at the top of the support rod.

[0007] As a further optimization of the aforementioned tooling for rapid measurement of the engagement amount of a lead screw welded assembly, a pre-drilled threaded hole is provided on the side wall of the square base, and a screw is screwed into the pre-drilled threaded hole to lock the lower toothed sleeve and the bottom of the guide rod.

[0008] A method for rapidly measuring the engagement amount of a lead screw weld assembly includes the following steps: Step 1: First, secure the lower toothed sleeve with screws; Step two, then fix the upper toothed sleeve onto the positioning sleeve; Step 3: Rotate the locking nut, positioning sleeve, and limiter to a suitable position that allows them to contact the welded components of the lead screw, ensuring that the V-shaped teeth of the welded components of the lead screw mesh with the V-shaped teeth of the lower toothed sleeve. Step four, then weld the upper toothed sleeve to the lead screw to form the upper part into which the gauge plate is installed; Step 5: Tighten the locking nut, limit switch, and positioning pin. Remove the gauge plate and manually rotate the lead screw assembly. If the lead screw assembly breaks through the engagement of the lower toothed sleeve and can rotate, it is determined that the V-tooth engagement of the lead screw assembly exceeds the standard. Conversely, if the lead screw assembly does not break through the engagement of the lower toothed sleeve and cannot rotate, it is determined that the V-tooth engagement of the lead screw assembly meets the standard.

[0009] As a further optimization of the aforementioned tooling for rapid measurement of the meshing amount of a lead screw welded assembly, the meshing amount of lead screw welded assemblies of different sizes can be measured by changing different gauge plates.

[0010] Compared with the prior art, the beneficial effects of the present invention are: First, the tooling of this invention includes a circular platform, a rotating mechanism, and a measuring mechanism. The circular platform is located at the bottom of the rotating mechanism, and the measuring mechanism is located at the top of the rotating mechanism. This tooling is suitable for measuring the welding composition of the bogie screw of an electric locomotive. It has the advantages of convenient operation, strong practicality, high flexibility, simple clamping, and rapid measurement.

[0011] Second, the measuring method of the measuring fixture of this invention is ingeniously designed, capable of clamping multiple lead screws welded together at once, offering high flexibility, simple clamping, rapid measurement, and convenient use and maintenance, thus reducing the workload and labor intensity of measurement. Third, this invention is highly versatile, reusable, simple in structure, and easy to operate, thus improving enterprise efficiency. Attached Figure Description

[0013] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a rapid measurement fixture for the meshing amount of a lead screw weld assembly includes a circular platform 1, a rotating mechanism 2, and a measuring mechanism 3. The circular platform 1 is located at the bottom of the rotating mechanism 2, and the measuring mechanism 3 is located at the top of the rotating mechanism 2. The measuring mechanism 3 includes a square base 301, a lower toothed sleeve 302, an upper toothed sleeve 303, a guide rod 304, a limiter 305, a toothed ring positioning shaft 306, a positioning sleeve 307, a positioning pin 308, a gauge plate 309, a locking nut 310, and a screw 311. The guide rod 304 is fixedly mounted on the square base 301, and one side of the guide rod 304 is provided with... A lower toothed sleeve 302 meshes with a lead screw; a positioning sleeve 307 is fitted onto a guide rod 304, and a limiter 305 is provided at the lower end of the positioning sleeve 307. A positioning pin 308 is installed on the side wall of the limiter 305, and the positioning pin 308 is inserted into a reserved hole on the guide rod 304 to fix the limiter 305; a locking nut 310 is provided at the upper end of the positioning sleeve 307, and the positioning sleeve 307 is locked and fixed by tightening the locking nut 310; one end of the positioning sleeve 307 gradually decreases outward to form a tapered part, and an upper toothed sleeve 303 is provided at the lower end of the tapered part, which is opposite to and matches the lower toothed sleeve 302.

[0015] like Figure 2 As shown, Figure 2 This is a schematic diagram of the connection between the circular platform and the rotating mechanism; the rotating mechanism 2 includes a rotating shaft 201 set at the center of the circular platform 1, three support frames 202 are evenly arranged outward in the horizontal direction on the rotating shaft 201, a cylinder 203 is set at the far end of the support frame 202, a support rod 204 is sleeved inside the cylinder 203, a rotating wheel 205 that travels on the circular platform 1 is set at the bottom of the support rod 204, and a measuring mechanism 3 is set at the top of the support rod 204.

[0016] The square base 301 has a pre-drilled threaded hole on its side wall. The screw 311 is screwed into the pre-drilled threaded hole to lock the bottom of the lower toothed sleeve 302 and the guide rod 304.

[0017] like Figure 6 As shown, Figure 6 This is a schematic diagram of the welded screw assembly. The welded screw assembly is a key component for brake release in brake calipers. During the production or maintenance of the welded screw assembly of the brake caliper, it is necessary to measure the meshing amount of the V-shaped teeth of the welded screw assembly to ensure the accuracy of the screw during use.

[0018] In actual use, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the measurement status of a single measuring mechanism; the measurement method of this invention is as follows: Step 1: First, fix the lower toothed sleeve 302 with screw 311; Step two, then fix the upper toothed sleeve 303 onto the positioning sleeve 307; Step 3: Rotate the locking nut 310, positioning sleeve 307, and limiter 305 to a suitable position that allows them to contact the welded components of the lead screw, ensuring that the V-shaped teeth of the welded components of the lead screw mesh with the V-shaped teeth of the lower toothed sleeve 302. Step four, then weld the upper toothed sleeve 303 to the lead screw to form the upper part into which the plate gauge 309 is installed; Step 5: Tighten the locking nut 310, limiter 305, and positioning pin 308. Pull out the gauge plate 309 and manually rotate the lead screw welding assembly. When the lead screw welding assembly breaks through the engagement of the lower toothed sleeve 302 and can rotate, it is determined that the V-tooth engagement amount of the lead screw welding assembly exceeds the standard; conversely, when the lead screw welding assembly does not break through the engagement of the lower toothed sleeve 302 and cannot rotate, it is determined that the V-tooth engagement amount of the lead screw welding assembly meets the standard.

[0019] By using sheet gauge 309 of different thicknesses, measurements of lead screw welded components with different meshing dimensions can be achieved.
