Description

Technical Field

[0001] This utility model relates to the field of bogie frame manufacturing technology for rail passenger cars, and in particular to a testing tool for bolster adjustment. Background Technology

[0002] In the past, bogie frames were mostly adjusted for elevation changes using cold adjustments. Inspection methods primarily involved using height gauges and steel rulers to check and confirm the adjusted elevation dimensions. The re-inspection process required re-determining the Z-axis reference dimensions and the dimensions to be inspected after adjustment. Each adjustment required adjusting the height gauge and the four corners of the frame, which was time-consuming, labor-intensive, and overly reliant on manual data verification, leading to significant errors.

[0003] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a testing tool for bolster adjustment. Utility Model Content

The detection position of the lower cover of the rocking pillow is detected by the long detection rod structure. The detection standard is that the detection head of the long detection rod structure can extend into the detection position of the lower cover of the rocking pillow within a certain range.

[0011] The brake mount hole detection structure has a positioning pin for detecting the brake mount hole, and the detection standard is that the positioning pin can extend into the corresponding brake mount hole.

[0012] Furthermore, the rocker arm is fixed to the rocker arm adjustment fixture, which has a fixture table and multiple supports fixed to the fixture table and a support platform for fixing the rocker arm.

[0013] The lower end of the long detection rod structure is attached to the tooling table surface, and the upper end of the long detection rod structure is the detection head of the long detection rod.

[0021] The bolt head structure at the top of the long detection rod is installed on the long detection rod detection head support seat.

[0022] Furthermore, the length of the major axis of the elongated hole in the long detection rod is 2.5 mm.

[0053] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0054] See Figures 1 to 10 As shown;

[0055] This embodiment provides a bolster adjustment testing tool, which is used to detect different positions of the bolster 20, and the testing tool is divided into:

[0056] The short detection rod structure 2 for detecting the upper cover 21 of the bolster, the long detection rod structure 1 for detecting the lower cover 22 of the bolster, and the brake mount hole detection structure 3 for detecting the brake mount hole;

[0057] Both the short detection rod structure 2 and the long detection rod structure 1 are positioned at the corresponding positions of the adjustment fixture 10 used to place the bolster 20.

[0058] The detection position of the rocking pillow 20's upper cover 21 is a symmetrical structure. The detection position of the upper cover 21 is detected by the short detection rod structure 2, and the detection standard is that the detection head of the short detection rod structure 2 can extend into the detection position of the upper cover 21 within a certain range.

[0059] The detection position of the lower cover 22 of the rocking pillow 20 is a symmetrical structure. The detection position of the lower cover 22 of the rocking pillow is detected by the long detection rod structure 1, and the detection standard is that the long detection rod detection head of the long detection rod structure 1 can extend into the detection position of the lower cover 22 of the rocking pillow within a certain range.

[0060] The brake mount hole detection structure 3 has a positioning pin 302 for detecting the brake mount hole, and the detection standard is that the positioning pin 302 can extend into the corresponding brake mount hole.

[0061] Specifically, this embodiment discloses various detection tools for detecting different positions of the bolster 20. These mainly consist of a short detection rod structure 2 for detecting the upper bolster cover 21, a long detection rod structure 1 for detecting the lower bolster cover 22, and a brake mount hole detection structure 3 for detecting the brake mount hole of the bolster 20. Combined with the structure of the adjustment fixture 10 for the bolster 20, each detection tool in this embodiment is arranged in its corresponding position. Since the upper bolster cover 21 has a symmetrical structure, all positions of the upper bolster cover 21 can be detected by the short detection rod structure 2; similarly, since the lower bolster cover 22 has a symmetrical structure, all positions of the lower bolster cover 22 can be detected by the long detection rod structure 1. However, the prior art does not have a detection tool for the brake mount 23. Therefore, this embodiment designs a brake mount hole detection structure 3 that matches the brake mount hole to detect the brake mount 23.

[0062] See Figure 1 As shown, in this embodiment, the rocker 20 is fixed on the rocker adjustment fixture 10. The rocker adjustment fixture 10 has a fixture table 11 and a support platform 12 fixed to the fixture table 11 for supporting and fixing the rocker 20.

[0063] Based on the existing structure of the bolster adjustment fixture 10, the lower end of the long detection rod structure 1 in this embodiment is attached to the fixture table 11, and the upper end of the long detection rod structure 1 is the long detection rod detection head; secondly, the short detection rod structure 2 in this embodiment is set on the support platform 12 used to support the bolster cover 21, and the upper end of the short detection rod structure 2 is the end detection rod detection head.

[0064] See Figures 2 to 5 As shown, preferably, the long detection rod structure 1 in this embodiment includes:

[0065] The long detection rod base 101 has a long detection rod mounting groove 106 machined on the upper part along the axial direction of the long detection rod structure 1, and a long detection rod elongated hole 107 machined on the upper part of the long detection rod base 101 along the radial direction of the long detection rod structure 1.

[0066] The long detection head is movably connected to the long detection rod mounting slot 106 of the long detection rod base 101, and the long detection rod head can move along the long detection rod mounting slot 106.

[0067] In this embodiment, the long detection rod detection head includes a long detection rod detection head spring 102 located in the long detection rod mounting groove 106; a long detection rod detection head support 103 connected to the long detection rod detection head spring 102, and a long detection rod limiting bolt 105 is radially installed on the long detection rod detection head support 103, the long detection rod limiting bolt 105 passing through the long detection rod elongated hole 107; and a long detection rod top bolt head structure 104 installed on the long detection rod detection head support 103.

[0068] In this embodiment, the long detection rod detection head can move within the long detection rod mounting groove 106. Since the bottom of the long detection rod detection head spring 102 is connected, it can be reset using the spring. Furthermore, a long detection rod elongated hole 107 is machined on the side of the long detection rod, and the major diameter of the long detection rod elongated hole 107 is used to control the range of the long detection rod detection head, thereby ensuring the accuracy of the detection.

[0069] Preferably, in this embodiment, the length of the major diameter of the long detection rod's elongated hole 107 is 2.5 mm. Based on the major diameter of the long detection rod's elongated hole 107, where the theoretical value for adjustment is the median of the range, the adjustment must meet a dimensional tolerance of 550 ± 1.25 mm, which is the permissible range for the adjustment area.

[0070] See Figures 6 to 9 As shown, preferably, the short detection rod structure 2 in this embodiment includes:

[0071] The short detection rod base 201 has a short detection rod mounting groove 206 machined on its upper part along the axial direction of the short detection rod structure 2, and a short detection rod elongated hole 207 machined on its upper part along the radial direction of the short detection rod structure 2.

[0072] The short detection head is movably connected to the short detection rod mounting slot 206 of the short detection rod base 201, and the short detection head can move along the short detection rod mounting slot 206.

[0073] The short detection rod detection head in this embodiment includes:

[0074] The short detection rod detection head spring 202 is located in the short detection rod mounting slot 206;

[0075] A short detection rod head support 203 is connected to the short detection rod head spring 202, and a short detection rod limiting bolt 205 is radially mounted on the short detection rod head support 203. The short detection rod limiting bolt 205 passes through the elongated hole 207 of the short detection rod; and

[0076] The short probe top bolt head structure 204 is installed on the short probe probe head support 203.

[0077] Preferably, in this embodiment, the major diameter of the oblong hole 207 of the short detection rod is 2.5 mm. The structure of the short detection rod structure 2 in this embodiment is similar to that of the long detection rod structure 1, and based on the fact that the major diameter of the oblong hole 207 of the short detection rod is 2.5 mm, the theoretical adjustment value is the median of the measurement range. Therefore, the adjustment must meet the dimensional tolerance requirement of 550 ± 1.25 mm, which is the permissible range for the adjustment area.

[0078] See Figure 10 As shown, the brake mount hole detection structure 3 of this embodiment includes a base plate 301; two positioning pins 302 are symmetrically arranged on the base plate 301, and the outer diameter of the positioning pins 302 matches the brake mount hole.

[0079] This utility model also discloses a method for testing the adjustment of a rocker arm. This testing method is based on the testing tool described above and mainly includes the following steps:

[0080] S1. First, place the rocker 20 on the rocker adjustment fixture 10 and fix it in place;

[0081] S2. Use the long detection rod structure 1 to detect the detection position of the lower cover 22 of the bolster. If the long detection rod structure 1 cannot be inserted into the detection position of the lower cover 22 of the bolster within the extension range, the position needs to be flame-adjusted. After the adjustment and cooling, use the long detection rod structure 1 to re-inspect until the long detection rod structure 1 can be inserted into the detection position of the lower cover 22 of the bolster within the extension range. This indicates that the adjustment is qualified.

[0082] S3. Use the short detection rod structure 2 to detect the detection position of the bolster cover 21. If the short detection rod structure 2 cannot be inserted into the detection position of the bolster cover 21 within the extension range, the position needs to be flame-adjusted. After the adjustment and cooling, use the short detection rod structure 2 to re-inspect until the short detection rod structure 2 can be inserted into the detection position of the bolster cover 21 within the extension range. Then the adjustment is qualified.

[0083] S4. Use the brake mount hole detection structure 3 to inspect the hole of the bolster brake mount 23. If the positioning pin 302 of the brake mount hole detection structure 3 cannot be inserted into the brake mount hole, perform cold adjustment using a turbine pump. After adjustment, re-inspect the brake mount hole using the brake mount hole detection structure 3 until the positioning pin 302 can be inserted into the corresponding brake mount hole. This indicates that the adjustment is qualified.

[0084] The above technical solution provides a testing tool and method for adjusting a rocker bolster, which has the following beneficial effects:

[0085] To meet the requirement of convenient and simple dimensional re-inspection after adjustment, the inspection tool of this utility model specifies the bolster adjustment process as flame adjustment, i.e., hot adjustment. However, after hot adjustment, a specially designed inspection device is used to inspect the inspection position. If the inspection meets the requirements, the adjustment is considered qualified; otherwise, further adjustment is required. This allows for rapid adjustment and inspection, meeting the dimensional requirements of each component. It avoids the need for multiple adjustments to height gauges and other measuring tools, preventing excessive reliance on manual confirmation and the potential for data deviation. This significantly improves labor efficiency and reduces repetitive tasks such as adjusting height gauges.

[0086] This invention utilizes multiple detection devices to quickly and effectively detect the dimensions of various parts of the bolster after adjustment. Compared with existing detection tools and scribing machines, it greatly saves time in the transition between adjustment and scribing processes and in adjusting process dimensions, improves work efficiency, and avoids human error.

[0087] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
