Description

Technical Field

[0001] The utility model relates to the technical field of triangular support processing and positioning equipment, in particular to a triangular support processing and positioning device for high-speed railways. Background Art

[0002] The triangular bracket used in high-speed rail construction is first cast into a blank during processing, and then drilled by a drilling machine to complete the processing of a triangular bracket.

[0003] Since the triangle support is in the shape of a triangle, it cannot be clamped on a drilling machine, and a positioning device is required to position the triangle support. The existing positioning device can only drill a hole at one corner of the triangle support at a time when the triangle support is fixed for drilling. When drilling holes at the positions of the other two corners of the triangle support, it is necessary to readjust the position of the triangle support, remove the triangle support, and then change the position and re-fix it on the positioning device, which makes the operation more cumbersome and reduces the processing efficiency of the triangle support.

[0004] Therefore, an optimization and improvement is proposed to solve the above problems by using a positioning device for processing a triangular support. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a triangular support processing and positioning device for high-speed railways, which is characterized by comprising a mounting plate, a rotating shaft, a rotating plate, a limit pin, an upper pressure plate, a limit assembly, and a reinforcement mechanism.

[0006] The mounting plate is connected to the rotating plate through a rotating shaft, a placement groove for placing the triangular bracket is arranged on the rotating plate, the upper part of the rotating plate is connected to the connecting part arranged on the outer wall of the upper pressure plate through a bolt, three limiting parts are arranged on the outer wall of the rotating plate at intervals, a limiting hole is arranged on the limiting part, and the limiting hole of the limiting part is connected to the latch hole arranged on the mounting plate through a limiting pin, and an installation limiting assembly is arranged on the mounting plate at a position beside the latch hole, and both ends of the rotating plate are respectively connected to the reinforcement mechanism installed on the mounting plate.

[0007] The limit assembly is composed of a fixed block, a spring and a telescopic block. The fixed block is fixedly arranged on the mounting plate beside the pin hole. The telescopic block is slidably connected in the telescopic groove arranged on the fixed block. A spring is arranged between the telescopic block and the bottom of the telescopic groove.

[0008] The reinforcement mechanism is composed of a fixing plate, an adjusting screw and a top plate. The fixing plate is screwed and fixedly mounted on the mounting plate. The adjusting screw is threadedly connected in a threaded hole arranged on the fixing plate. One end of the adjusting screw is provided with a top plate.

[0009] Specifically, a drilling groove is arranged on the bottom of the placement groove, and each drilling groove corresponds to a position to be drilled on the triangular support.

[0010] Specifically, the telescopic block is in contact with the limiting part of the rotating plate. When the limiting pin needs to be inserted to limit and fix the position of the rotating plate, the limiting part of the rotating plate is pushed to move to the next limiting part to abut the telescopic block, thereby completing the alignment of the limiting hole and the pin hole, and quickly inserting the limiting pin.

[0011] Specifically, each limiting portion on the rotating plate corresponds to each corner of the triangular bracket, and each time the position of the limiting portion of the rotating plate is adjusted, the position of the triangular bracket is adjusted.

[0012] Specifically, mounting holes are provided at four corners of the mounting plate for mounting the positioning device on a processing drilling machine.

[0013] Beneficial effects of the utility model:

The whole operation does not need to disassemble and remove the triangular support for many times to adjust the position, and the operation is convenient.

[0015] The limiting assembly installed on the mounting plate is arranged beside the latch hole, and the telescopic block that can be moved up and down accelerates the alignment of the limiting part of the rotating plate with the latch hole on the mounting plate, and the limiting pin is quickly inserted to complete the limiting fixation of the rotating plate, thereby improving the processing efficiency;

[0016] The processing mechanism installed at both ends of the mounting plate controls the movement of the top plate by operating the adjustment screw, and the top plate abuts against the rotating plate to further limit and fix the position of the rotating plate, thereby reducing the shaking of the rotating plate during the drilling of the triangular support and improving the processing stability.

[0024] Example 1

[0025] As shown in the figure, mounting holes 11 are provided at four corners of the mounting plate 1 for mounting the positioning device on a processing drilling machine. The mounting plate 1 is connected to the rotating plate 3 through the rotating shaft 2. A placement groove 31 for placing the triangular support 100 is provided on the rotating plate 3. A drilling groove 311 is provided on the bottom of the placement groove 31. Each drilling groove 311 corresponds to a position to be drilled on the triangular support 100. The bolt hole 33 provided above the rotating plate 3 is used for fixed connection with a connecting portion provided on the outer wall of the upper pressing plate 4 through a bolt 5. Three limiting portions 31 are arranged at intervals on the outer wall of the rotating plate 3, wherein each limiting portion 31 on the rotating plate 3 corresponds to each corner of the triangular support 100. Each time the position of the limiting portion 31 of the rotating plate is adjusted, the position of the triangular support 100 is adjusted. A limiting hole 311 is provided on the limiting portion 31, and the limiting hole 311 of the limiting portion 31 is connected to the pin hole 12 provided on the mounting plate 1 through a limiting pin 8.

[0026] A limiting assembly for limiting the limiting portion 31 of the mounting plate 1 is arranged on the mounting plate 1 at a position beside the latch hole 12. The limiting assembly is composed of a fixed block 61, a spring 63 and a telescopic block 62. The fixed block 61 is fixedly arranged on the mounting plate 1 at a position beside the latch hole 12. The telescopic block 62 is slidably connected in a telescopic groove 611 arranged on the fixed block 61. A spring 63 is arranged between the telescopic block 62 and the bottom of the telescopic groove 611. The telescopic block 62 is in contact with one side of the limiting portion 31 of the rotating plate 3.

[0027] When positioning the triangular support 100, the two ends of the rotating plate 3 are respectively connected to the reinforcement mechanism installed on the mounting plate 1, and the reinforcement mechanism is composed of a fixed plate 71, an adjusting screw 72 and a top plate 73. The fixed plate 71 is fixedly mounted on the mounting plate 1 by screws, and the adjusting screw 72 is threadedly connected in the threaded hole set on the fixed plate 71, and one end of the adjusting screw 72 is equipped with a top plate 73.

[0028] Specifically, the telescopic block is in contact with the limiting part of the rotating plate. When the limiting pin needs to be inserted to limit and fix the position of the rotating plate, the limiting part of the rotating plate is pushed to move to the next limiting part to abut the telescopic block, thereby completing the alignment of the limiting hole and the pin hole, and quickly inserting the limiting pin.

[0029] Example 2

[0030] The utility model is installed on a processing drilling machine through the mounting holes 11 set at the four corners of the mounting plate 1. When drilling the triangular bracket 100, first place the triangular bracket 100 in the placement groove 32 of the rotating plate 3, and then put the upper pressing plate 4 on the triangular bracket 100, connect the upper pressing plate 4 with the rotating plate 3 through the bolts 5, and screw the bolts 5 to make the upper pressing plate 4 press downward against the rotating plate 3, so that the upper pressing plate 4 limits the triangular bracket 100 in the placement groove 32 of the rotating plate 3. At this time, the connecting portion 31 of the rotating plate 3 is limitedly connected with the pin hole 12 of the mounting plate 1 through the limiting pin 8, and the top plates in the fixing mechanisms at both ends of the rotating plate 3 are in contact with the outer wall of the rotating plate 3.

[0031] After the screw rod 72 is adjusted, the top plate 73 is moved back to its original position, and the stop pin 8 is removed to release the stop pin 8 from the rotation plate 3. Then, the telescopic block 62 is pressed downward to move it into the fixed block 61. At this time, the telescopic block 62 does not block the stop portion 31 of the rotation plate 3, and the rotation plate 3 is pushed to rotate from the stop assembly. Due to the expansion and contraction of the spring 63, the telescopic block 62 is reset, and the next stop portion 31 provided on the rotation plate 3 is rotated and contacts with the telescopic block 62, and then the stop portion 31 of the rotation plate 3 is not rotated, so as to accelerate the alignment of the stop portion 31 of the rotation plate 3 with the pin hole 12 on the mounting plate 1, and the stop pin 8 is quickly inserted to complete the stop fixation of the rotation plate 3, thereby improving the processing efficiency; and by operating the adjustment screw 72 to control the movement of the top plate 73, the top plate 73 abuts against the rotation plate 3, further limiting and fixing the position of the rotation plate 3, reducing the shaking of the rotation plate 3 during the drilling process of the triangle support 100, thereby affecting the drilling process of the triangle support 100, and improving the processing stability.

[0032] The utility model realizes adjusting the position of the hole to be drilled on the triangular support 100 by rotating the rotating plate 3 to correspond to the drilling assembly on the drilling machine. The whole operation does not need to disassemble and remove the triangular support 100 multiple times to adjust the position, which makes the operation convenient during processing and greatly improves the processing efficiency.
