Description

Technical Field

[0001] This invention relates to the field of relay assembly tools, and more particularly to a drilling auxiliary device for a tie rod assembly for railway signal relays. Background Technology

[0002] Currently, in railway signal relay pull rod assemblies, the mica plate is inserted between the upper and lower clamping plates. The upper and lower clamping plates are then struck to cause plastic deformation, thus clamping the mica plate securely. However, sometimes insufficient clamping force between the upper and lower clamping plates causes relative displacement between the mica plate and the pull rod body. To solve this problem, a through hole is drilled in the surfaces of the upper clamping plates and the mica plate, and then they are fastened together by riveting. However, existing technology lacks an auxiliary device for drilling holes in relay pull rod assemblies, resulting in low drilling efficiency and inconsistent hole size and position, reducing processing efficiency and product quality. Summary of the Invention

[0003] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a drilling auxiliary device for tie rod assemblies for railway signal relays. By setting a drilling positioning block with a drilling through hole and a limiting baffle, the drilling efficiency of the tie rod assembly is improved, and the drilling size and position of each tie rod assembly are consistent.

[0004] To achieve the above objectives, the main technical solutions adopted by the present invention include: A drilling auxiliary device for a tie rod assembly for a railway signal relay includes a first worktable and a second worktable. The second worktable is positioned above and connected to the first worktable. A limiting baffle is provided at one end of the second worktable, and a drilling positioning block connected to the second worktable is provided on the opposite side of the limiting baffle. A drilling through hole is provided on the drilling positioning block, and the distance between the limiting baffle and the drilling positioning block matches the distance between the upper and lower clamping plates of the tie rod assembly.

[0005] Furthermore, a first worktable groove is provided on the first worktable, and the first worktable groove is located at the contact part between the first worktable and the second worktable.

[0006] Furthermore, the top of the limiting baffle is higher than the upper surface of the second worktable. The limiting baffle is connected to one side of the second worktable by an adjusting screw. The adjusting screw is threadedly connected to the second worktable. The side of the adjusting screw away from the second worktable is a smooth rod part. The limiting baffle passes through the smooth rod part of the adjusting screw. A spring is sleeved on the outside of the smooth rod part between the nut of the adjusting screw and the limiting baffle.

[0007] Furthermore, a drilling positioning block is provided above one end of the second worktable relative to the limiting baffle. The drilling positioning block includes a drilling positioning block fixing part and a drilling positioning block extension part. The drilling positioning block fixing part is connected to the second worktable. The drilling positioning block extension part extends towards the clamping plate on the pull rod assembly and the direction to be drilled on the mica plate. A drilling through hole is opened on the drilling positioning block extension part.

[0008] Furthermore, a second worktable boss is provided on the side of the second worktable connected to the drilling positioning block, and the height of the second worktable boss matches the thickness of the clamping plate on the tie rod assembly.

[0009] The beneficial effects of this invention are: using the drilling auxiliary device for railway signal relay tie rod assemblies of this invention to drill holes in the tie rod assembly can improve the efficiency of the drilling process, ensure the consistency of hole size and position, and improve processing efficiency and product quality. By drilling a through hole of equal size and in the same position on the surface of the upper clamping plate and the mica plate in the tie rod assembly, and then fixing the two by riveting, the problem of relative displacement between the internal mica plate and the tie rod body caused by insufficient clamping force of the upper and lower clamping plates is solved.

Detailed Implementation

[0012] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "up," "down," "left," and "right" are used interchangeably. Figure 1 The orientation is used as a reference.

[0013] Tie rod assembly for railway signal relays, such as Figure 2As shown, it includes a pull rod 4, an upper clamping plate 5, a lower clamping plate 6, and a mica plate 7. The upper clamping plate 5 and the lower clamping plate 6 are vertically connected to the pull rod 4. The mica plate 7 is fixed between the upper clamping plate 5 and the lower clamping plate 6. After the mica plate 7 is placed between the upper clamping plate 5 and the lower clamping plate 6, holes are drilled at the contact positions between the upper clamping plate 5, the lower clamping plate 6 and the mica plate 7 to facilitate the connection between the upper clamping plate 5, the lower clamping plate 6 and the mica plate 7 by riveting.

[0014] This invention provides a drilling auxiliary device for a tie rod assembly used in railway signal relays, such as... Figure 1 As shown, the assembly includes a first workbench 1 and a second workbench 2. Specifically, both the first workbench 1 and the second workbench 2 are rectangular structures made of carbon steel. The second workbench 2 is positioned above and connected to the first workbench 1. Specifically, the first workbench 1 is the lower layer, and the second workbench 2 is the upper layer. The first workbench 1 and the second workbench 2 are connected by two hexagonal socket head cap screws 2-2. A limiting baffle 2-3 is provided at one end of the second workbench 2. A drilling positioning block 3, connected to the second workbench 2, is provided on the opposite side of the limiting baffle 2-3. The drilling positioning block 3 has a through hole 3-3, which matches the position to be drilled. The distance between the limiting baffle 2-3 and the drilling positioning block 3 matches the distance between the upper and lower clamping plates of the tie rod assembly. The limiting baffle 2-3 and the drilling positioning block 3 are used to position the upper clamping plate 5 and the lower clamping plate 6 on the left and right sides of the assembly mica plate 7.

[0015] Specifically, since the first workbench 1 and the second workbench 2 are in surface-to-surface contact, in order to prevent unevenness of the contact surface that may occur after long-term use, a first workbench groove 1-1 is provided on the first workbench 1. The first workbench groove 1-1 is located at the contact part between the first workbench 1 and the second workbench 2. The first workbench groove 1-1, together with the hex socket screw 2-2, slightly adjusts the contact surface between the first workbench 1 and the second workbench 2.

[0016] For ease of operation, the limiting baffle 2-3 can be configured as a telescopic structure. Specifically, the limiting baffle 2-3 is located at one end of the second worktable 2, with its top higher than the upper surface of the second worktable 2, the protruding portion used to contact the side of the lower clamping piece 6. More specifically, the limiting baffle 2-3 is connected to one side of the second worktable 2 via an adjusting screw 2-4. The adjusting screw 2-4 is threaded to one end of the second worktable 2, with a smooth rod portion on the side of the adjusting screw 2-4 away from the second worktable 2. The limiting baffle 2-3 passes through the smooth rod portion of the adjusting screw 2-4, and a spring 2-5 is fitted around the smooth rod portion between the nut of the adjusting screw 2-4 and the limiting baffle 2-3. This allows the limiting baffle 2-3 to telescopically move left and right relative to the second worktable 2 using the spring 2-5, facilitating operation and clamping of the upper and lower clamping pieces.

[0017] Specifically, a drilling positioning block 3 is provided above one end of the second workbench 2 relative to the limiting baffle 2-3. The drilling positioning block 3 includes a drilling positioning block fixing part 3-1 and a drilling positioning block extension part 3-2. The drilling positioning block fixing part 3-1 is connected to the second workbench 2, and the drilling positioning block extension part 3-2 extends towards the direction to be drilled between the clamping piece 5 of the pull rod assembly and the mica plate. A drilling through hole 3-3 is provided on the drilling positioning block extension part 3-2. More specifically, the drilling positioning block 3 can be L-shaped, with one side connected to the top of the second workbench 2 by an internal hexagonal screw, and the other side extending towards the position to be drilled. A drilling through hole 3-3 is provided on the drilling positioning block extension part 3-2. During drilling, the drilling positioning block 3 is located above the pull rod assembly, and the drill bit drills from top to bottom through the drilling through hole 3-3 to drill the connection position between the clamping piece 5 and the mica plate. More specifically, the second worktable 2 is provided with a second worktable boss 2-1 on the side connected to the drilling positioning block 3. The height of the second worktable boss 2-1 matches the thickness of the clamping piece 5 on the tie rod assembly, so that the drilling through hole 3-3 can be located above the position to be drilled.

[0018] In use, the second workbench 2 is fixed to the upper surface of the first workbench 1 using hex socket screws 2-2. One end of the second workbench 2 is a retractable limiting baffle 2-3, and the other end is a drilling positioning block 3. After placing the mica plate 7 between the upper clamping plate 5 and the lower clamping plate 6, the upper and lower clamping plates and the mica plate 7 are placed between the limiting baffle 2-3 and the drilling positioning block 3. The limiting baffle 2-3 can be manually pulled. After releasing, the limiting baffle 2-3 returns to its original position. It works with the drilling positioning block 3 to clamp the left and right sides of the upper and lower clamping plates, so that the drill bit drills through the drilling through hole 3-3 to drill a hole at the connection position between the upper clamping plate 5 and the mica plate 7. After drilling is completed, the limiting baffle 2-3 is pulled to take out the pull rod assembly. After drilling, the pull rod assembly is taken out and proceeded to the riveting process.

[0019] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any modifications, alterations, substitutions, and variations made by those skilled in the art to the above embodiments are within the scope of the present invention.
