Description
Technical Field
[0001] The utility model relates to the field of transmission shaft assemblies, in particular to a front transmission intermediate flange straightening and detection tool. Background Art
[0002] like Figure 1 、 2 As shown, in the prior art, when aligning and testing the front transmission assembly (7'), two measuring rods (1') are inserted into a set of tooth grooves (5') of the middle flange (4'), and then a plate (3') is placed on the measuring rods. Finally, a strong magnet (2') is placed in the middle of the plate to firmly fix the measuring rods and the plate. According to the above steps, the measuring rods and the plate are installed in the four sets of tooth grooves of the middle flange. The contact of the dial indicator can be placed at the meter detection position (6') so that it contacts the outer edge of the plate. Then, the front transmission assembly is rotated to detect the verticality of the four plates.
[0003] However, the prior art has the following defects:
[0004] 1. The tooling installation is troublesome and requires the installation of four detection surfaces, resulting in low detection efficiency;
[0005] 2. Due to the differences in the position of the measuring rod when it is installed, the repeatability of the test is poor and the test accuracy is low. Utility Model Content
[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a front-end intermediate flange straightening detection tool to solve the problem of troublesome installation and low efficiency; to avoid the problem of poor detection repeatability caused by differences in the installation position of the measuring rod.
[0007] The purpose of the present utility model is achieved through the following technical solutions: this front transmission intermediate flange straightening detection tool comprises a tool body and a front transmission shaft assembly, an intermediate flange fork is provided at one end of the front transmission shaft assembly, a tooth groove is provided on one side end face of the tool body, and the tooth groove is engaged with the end face teeth of the intermediate flange fork, and positioning holes are provided at corresponding positions of the tool body and the intermediate flange fork for inserting guide pins, thereby assembling the tool body to the intermediate flange fork; the back of the tool body is tightened by a tightening assembly, and the outer circle of the tool body away from the side of the intermediate flange fork is used as the detection position, and the contact of the dial indicator is pressed on the detection position, and the verticality detection of the end faces of the tool body and the intermediate flange fork is realized by rotating the front transmission shaft assembly.
[0008] As a further technical solution, the tightening assembly includes a mounting seat mounted on the lathe center, a steel ball embedded in the mounting seat, and a locking sleeve detachably mounted on the mounting seat. The locking sleeve presses the steel ball relative to the mounting seat, and the steel ball is exposed from the surface of the locking sleeve for tightening the back.
[0009] The beneficial effects of the utility model are:
[0010] 1. Easy to install. Just put the tool body into the middle flange fork, use the guide pin to guide the positioning, and then tighten it with the tightening assembly.
[0011] 2. Since the tooling body and the middle flange fork are fully engaged through the tooth shape, the repeatability and consistency of the detection are small and the detection accuracy is higher;
[0012] 3. When the steel ball is worn, the locking sleeve can be removed and replaced quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed introduction to the present invention with reference to the accompanying drawings:
[0021] Example: As shown in the attached Figures 3-5 As shown, this front transmission intermediate flange straightening and detection tooling includes an intermediate flange fork 1, a tooling body 2, a guide pin 3, a steel ball 4, a locking sleeve 5, a mounting seat 6, a lathe center 7, an end face tooth 8, a positioning hole 9, a detection position 10, a back 11 and a front transmission shaft assembly 12.
[0022] Reference Attachment Figure 3 、 4The front drive shaft assembly 12 is provided with an intermediate flange fork 1 at one end. A tooth groove is provided on one end face of the tool body 2 (i.e., the end face facing the intermediate flange fork 1). The tool body 2 uses the tooth groove to engage with the end face teeth 8 of the intermediate flange fork 1. At the same time, positioning holes 9 are provided at corresponding positions of the tool body 2 and the intermediate flange fork 1. The guide pin 3 is sequentially passed through the positioning holes 9 of the tool body 2 and the intermediate flange fork 1, thereby assembling the tool body 2 to the intermediate flange fork 1. Figure 3 shown.
[0023] like Figure 5 As shown, the tightening assembly includes a mounting seat 6 mounted on the lathe center 7, a steel ball 4 embedded in the mounting seat 6, and a locking sleeve 5 removably mounted on the mounting seat 6. The locking sleeve 5 presses the steel ball 4 against the mounting seat 6, and the steel ball 4 is exposed from the surface of the locking sleeve 5 to tighten the back 11. When the steel ball 4 is worn after long-term use, it can be quickly replaced by removing the locking sleeve 5.
[0024] Furthermore, the back 11 of the tool body 2 is tightened by a tightening component, and the outer circle of the tool body 2 facing away from the middle flange fork 1 is used as the detection position 10. The contact of the dial indicator is pressed on the detection position 10, and the verticality of the end faces of the tool body 2 and the middle flange fork 1 can be detected by rotating the front drive shaft assembly 12.
[0025] The present invention manufactures a tool body 2 with a tooth-groove structure, utilizing the tooth grooves of the tool body 2 to engage with the end face teeth 8 of the intermediate flange fork 1. Simultaneously, a guide pin 3 is sequentially passed through the positioning holes 9 of the tool body 2 and the intermediate flange fork 1 to assemble the tool body 2 onto the intermediate flange fork 1. The back 11 of the tool body 2 is tightened by a steel ball 4. Once the steel ball 4 wears, it can be quickly replaced by removing the locking sleeve 5. The outer circle of the tool body 2 facing away from the intermediate flange fork 1 is used as the detection position 10. The contact of the dial indicator is placed against the detection position 10. By rotating the front drive shaft assembly 12, the verticality of the end faces of the tool body 2 and the intermediate flange fork 1 can be detected.
[0026] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
