Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a flatness multi-position correction tool for a shell. Background Art

[0002] Railway transponders are point-type devices used to transmit information from the ground to trains. Their main purpose is to provide reliable ground fixed information and variable information to trains. They are responsible for accurately, timely and reliably obtaining train location information for fully automatic driving of urban rail transit. For example, after the train operation is completed, it must stop at the vehicle base operation warehouse for daily maintenance. In order to ensure that the automatically running train can stop safely and accurately at a fixed position, many transponders are installed in the maintenance trench of the vehicle base to assist the train in accurately stopping and starting.

[0003] The transponder includes an outer shell and electronic devices inside the shell. The outer shell is usually formed by compression molding, and due to the particularity of the transponder installation position, there are relatively strict requirements for the flatness of the outer shell. In order to ensure that the molded transponder shell meets the flatness requirements, conventional manufacturers use precision CNC equipment to achieve the target accuracy, but for some manufacturers, it is difficult to modify the original equipment. If the original equipment is eliminated and replaced with new production equipment, the investment will be large. Utility Model Content

[0022] The following is a further detailed description through specific implementation methods:

[0023] The marks in the drawings of the specification include: support frame 1, first frame 11, second frame 12, hollow portion 13, correction assembly 2, first correction block 21, second correction block 22, clamping assembly 3, clamp 31, clamping strip 32, main body 321, contact plate 322, clamp base 33, detection strip 4, shell 5, cavity 51.

[0024] The embodiment is basically as shown in the attached Figure 1 and Figure 2 As shown: A housing flatness multi-position correction tool, comprising a support frame 1, a correction component 2 and a clamping component 3.

[0025] The top surface shape of the support frame 1 is adapted to the shape of the target housing. In this embodiment, the target housing is a transponder housing 5. Figure 5 The structure of the housing 5 shown is a rectangular parallelepiped structure with an opening and a cavity 51. This is only a brief schematic diagram, which is only for the purpose of explaining the method of use, and does not limit other detailed structures. The top surface of the support frame 1 is rectangular in shape, and in this embodiment it is a rectangular frame design. The frame structure serves as a support shell and heat dissipation. During calibration, the target shell in a hot state is placed on the frame, and the hollow part of the frame can form a heat dissipation space. The support frame 1 includes a first frame 11 and a second frame 12 located below the first frame 11. The first frame 11 and the second frame 12 are as shown in FIG. Figure 1The second frame 12 is longer than the first frame 11 and is welded together. Figure 1 The connection between the second frame 12 and the first frame 11 (in the direction indicated by the arrow) has a hollow portion 13. Since the target shell is placed on the first frame 11 during calibration, the design of the hollow portion 13 can allow the hot air gathered inside the hollow of the frame to be promptly dissipated from the hollow portion 13, thereby accelerating heat dissipation. The first frame 11 and the second frame 12 have the same width, but can also be different. Because the different widths can also form a hollow to achieve faster heat dissipation. In this embodiment, the first frame 11 has a width of 250-300mm, a length of 950-1000mm, and a thickness T1 of 20-30mm; the second frame 12 has a length of 1050-1100mm;

[0026] The correction assembly 2 includes two first correction blocks 21 and two second correction blocks 22; the first correction block 21 and the second correction block 22 have a height difference and are respectively installed at preset positions on the top surface of the support frame 1, and the height difference and the preset position are adapted to the target flatness. In this embodiment, the first frame 11 includes two long sides and two short sides, and the two first correction blocks 21 are relatively installed on the two long sides and adapted to the first target detection position, the first target detection position can be the center line in the width direction of the shell, and the two second correction blocks 22 are relatively installed on the two short sides. The height of the first correction block 21 is 3-5mm, the length is 100-140mm, and the width is 15-20mm. The height of the second correction block 22 is 10-15mm, the length is the same as the width of the first frame 11, and the width is 25-30mm. The height difference is 5-12mm, which can meet the flatness requirements of the transponder shell of existing specifications.

[0027] The clamping assembly 3 includes two clamps 31 and a clamping strip 32. Figure 1 As shown, the clamp 31 can adopt the GH-203FL model quick clamp, the force is 230Kg, which can meet the clamping force requirements of this tooling, and the force applied to the shell is appropriate to ensure the quality of the shell; the two clamps 31 are relatively installed on both sides of the support frame 1 and the installation position corresponds to the first target detection position of the target shell. In this embodiment, the clamps 31 are installed at Figure 1 On the midline of the width direction of the first frame 11 shown; Figure 3As shown, the clamping strip 32 includes a main body 321 and two contact plates 322; the main body 321 is a rectangular parallelepiped structure, the two contact plates 322 are installed on the same side of the main body 321, and the installation position is adapted to the clamping position of the compressor 31 relative to the shell, the contact plate 322 exceeds the main body 321 and has extensions on both sides, the area of ​​the contact plate 322 is larger than the end area of ​​the compressor 31, the length of the clamping strip 32, that is, the length of the main body is adapted to the detection width of the first target detection position, and the length of the clamping strip 32 is 270-300mm.

[0028] like Figure 4 As shown, the tooling also includes two detection strips 4; the detection strips 4 are rectangular parallelepiped structures, and have step grooves at both ends in the length direction; the length of the detection strips 4 is adapted to the width of the second target detection position of the target shell.

[0029] The process of using this tool to correct the shell flatness is as follows:

[0030] The transponder housing 5 after compression molding has an opening and a cavity 51. The transponder housing 5 which is still in a hot state is placed on the first frame 11 with the opening facing upward. The length and width directions of the transponder housing 5 are respectively consistent with the length and width directions of the first frame 11. At this time, the first correction block 21 is located below the long side of the transponder housing 5, and the second correction block 22 is located at the transponder housing 5; the pressing strip 32 is placed on the transponder housing 5 and is located between the two pressing devices 31. At this time, the main body 321 of the pressing strip 32 is stuck in the cavity 51 of the transponder housing 5, and the length direction is consistent with the width direction of the transponder housing 5. The pressing strip 32 can be stably hung on the housing 5 by the part of the contact plate 322 that exceeds the main body 321; the pressing device 31 is pressed. At this time, the pressing device 31 is pressed against the contact plate 322. 322 presses against the pressing strip 32 with a large area, thereby applying downward force to the transponder housing 5, and performs flatness correction and adjustment on the hot transponder housing 5 based on the preset position and height difference of the first correction block 21 and the second correction block 22; the detection strip 4 is stuck in the cavity 51 of the transponder housing 5, and is placed at 1 / 4 and 3 / 4 of the length direction of the housing 5, respectively, to perform width detection; during the cooling process, the heat emitted by the hot transponder housing 5 will be gathered in the hollow parts of the first frame 11 and the second frame 12, and will be dissipated from the hollow parts in time; after the transponder housing 5 is cooled, the presser 31 is released, the pressing strip 32 is removed, the detection strip 4 is removed, the transponder housing 5 that has completed the flatness correction is taken out, and then the flatness correction of the next housing 5 can be performed. Multiple of this tooling can be set up to make adjustments at the same time to improve the adjustment efficiency.

[0031] The design of this tooling can complete the flatness correction without modifying or replacing the molding equipment, ensuring the correction quality and low cost. It is especially suitable for small-scale manufacturers to avoid the capital problem caused by replacing the molding equipment and has good economic benefits. The tooling has a simple structure and convenient operation. The combined structure is flexible and changeable. It can adapt to various specifications of shells and different flatness correction requirements through simple adjustment, and has strong versatility.
