Description

Technical Field

[0001] This utility model relates to the field of dimensional detection technology, specifically to a dimensional detection device for a combined brake beam support column of a railway freight car. Background Technology

[0002] The left and right struts are key components of the combined brake beam in the K6 type bogie for railway freight cars, and their dimensions for assembly and mating with the brake beam are all spatial dimensions. During manufacturing, the dimensions of the left and right struts need to be measured and controlled to facilitate the subsequent assembly of the brake beam. Conventional inspection methods cannot measure and inspect these critical spatial dimensions during manufacturing; therefore, a marking platform or coordinate measuring machine (CMM) is required for dimensional measurement.

[0003] However, the above methods are time-consuming, inefficient in measurement and inspection, and cannot promptly detect quality problems in the production process, resulting in a high rate of rework. Furthermore, during the assembly of the brake beam, the cumulative dimensional tolerances between the support column and the brake beam can easily lead to non-compliant assembly dimensions.

[0004] Therefore, in order to improve the detection accuracy of brake beam supports, the applicant, based on the existing support dimensions and structure, researched and designed a railway freight car combined brake beam support dimension detection device that can quickly measure and detect the spatial dimensions of the support, thereby improving the accuracy and efficiency of the measurement of the support spatial dimensions.

[0025] Combined with appendix Figures 1-5 A railway freight car combined brake beam support dimension detection device includes a base 1, a vertical plate 2 is vertically arranged above the base 1, a square hole 2-1 is provided on the top of the vertical plate 2, the square hole 2-1 is used to place an arc height template 3, an arc template 4 is arranged between two vertical plates 2, a front column 5 is vertically arranged above the front side of the base 1, a support body 7 is provided at the top of the front column 5, an upper cover 8 is provided above the support body 7 and cooperates with it, and a go / stop indicator 9 is placed between the support body 7 and the upper cover 8. The go / stop indicator 9 is used to detect the arc radius, the concentricity of the arc center and the height.

[0026] In a preferred embodiment, the base 1 is C-shaped, with a V-shaped protrusion 1-1 in the middle and a fixing connection through hole 1-2 on the side. The V-shaped protrusion 1-1 engages with the fixing connection through hole 1-2 to support and fix the support column. The V-shaped protrusion engages with the support column, and the fixing connection through hole is connected to the support column with bolts to fix the support column.

[0027] In a preferred embodiment, the base 1 has connecting holes 1-3 on both sides, and the two upright plates 2 are symmetrically arranged. Each of the two upright plates 2 has a connecting threaded hole 2-2 at its bottom. A connecting bolt is installed in the connecting hole 1-3. The connecting bolt is sized to the connecting hole 1-3 and the connecting threaded hole 2-2. The bottom of the upright plate 2 is fixedly connected to the base 1 by the connecting bolt.

[0028] In practice, the base has elongated grooves on both sides that fit into the bottom of the upright plate, and the bottom plate of the upright plate is inserted into these grooves. Connecting holes 1-3 are provided within the elongated grooves. The upright plate is then fixed to the base using bolts.

[0029] In a preferred embodiment, the base 1 has circular grooves 1-4 on both sides of its front portion. These grooves 1-4 are sized to fit the front column 5. The lower end of the front column 5 is inserted into the circular grooves 1-4. A connecting through hole 1-5 is provided within each circular groove 1-4, and a fixing bolt is installed within each connecting through hole 1-5. A fixing threaded hole 5-1 is provided at the bottom of the front column 5. The fixing bolt is sized to fit the fixing threaded hole 5-1 and the connecting through hole 1-5. In practice, the front column is vertically fixed to the upper front portion of the base using the fixing bolt.

[0030] In a preferred embodiment, a rotating body 6 is coaxially rotatably connected to the top of the front column 5. A support body 7 is fixedly connected to the upper end of the rotating body 6. The support body 7 is fixedly connected to the rotating body 6 by bolts, and the support body 7 is also fixedly connected to the upper cover 8 by bolts.

An elongated hole 9-1 is provided along the length of the center of the go / stop indicator 9, and the elongated hole 9-1 is slidably engaged with the central shaft 8-1.

[0031] In practical implementation, the rotating body can rotate freely 360 degrees around the central axis of the front column, and then the rotating body drives the supporting body to rotate freely 360 degrees, thereby enabling the go / stop sign to rotate freely 360 degrees. The go / stop sign can slide through the engagement of the elongated hole with the central shaft. The central shaft is a bolt; after the go / stop sign slides to the appropriate position, the bolt is tightened to fix the go / stop sign in place.

[0032] The base and template are made of special materials and processing techniques, possessing excellent wear resistance and impact resistance. During testing, the mounting platform is set up with the mounting groove of the support column and brake beam assembly as the reference to ensure consistency with the support column testing reference. The spatial angle is deflected at the height spatial coordinate of the pin hole, and a go / stop marker is set to test the height of the hole center. The go / stop marker can rotate 360°. An arc template is set at the height coordinate of the arc apex to test the arc radius, arc center concentricity, and height.

[0033] After the support column is machined, the operator can place it on the base, perform benchmark positioning according to the inspection method, and then use a go / no-go gauge to check the height tolerance between the center of the mounting groove and the pin hole; use an arc template to check the diameter and coaxiality of the press-fit arc surface, and use an arc height template to check the height tolerance between the mounting groove and the apex of the arc. This device allows the operator to easily identify problems that occur during the support column machining process and quickly make corrections. Furthermore, it allows for the selection of upper, lower, and middle tolerances based on the key dimensions of the support column. During assembly, the selected support column can be tolerance-matched with the brake beam frame to avoid cumulative tolerances causing assembly quality problems.
