Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of turnout pad processing equipment, specifically a turnout pad welding auxiliary device. Background Technology
[0002] Turnout base plates are iron plates placed between turnout rail components and turnout sleepers to provide reliable connection conditions for the turnout center and wing rails, and to distribute the wheel load of the rails to the sleeper surface. To facilitate fixing the turnout rails to the base plates, iron seats need to be welded onto them. During welding, manual marking is commonly used to solve the problem of positioning the iron seats, which is obviously inefficient. To improve the welding efficiency of the base plates, tooling is used to position the iron seats. However, existing tooling positions one iron seat on a base plate at a time, and a new base plate can only be clamped after welding is completed. Therefore, the improvement in welding efficiency is not significant and needs further improvement. Utility Model Content

Detailed Implementation
[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.
[0023] The following is a reference to the appendix. Figure 1 , 2 Section 3 details the preferred embodiments of this utility model:
[0024] Example 1: This utility model provides a turnout pad welding auxiliary device, including a base plate 100, a support frame 200, and a positioning frame 300. The base plate 100 is a steel plate, and its upper and lower surfaces are precision machined to ensure its flatness. The base plate 100 is mounted on a slewing frame (not shown in the figure) so that the base plate 100 can rotate on the slewing frame. It should be understood that the slewing frame of this utility model is a mechanism that can rotate around a central axis. The slewing frame includes a frame, a slewing shaft, bearings, etc. This slewing frame is prior art, and its structure is described below. The structure is not specifically limited, as long as it allows the base plate 100 to rotate. To improve the rigidity of the welding auxiliary device and prevent deformation during use, a support is provided below the base plate 100. The base plate 100 is mounted on a rotating frame via the support, thus forming a rotating worktable for the base plate 100. This makes the turnout pad welding auxiliary device of this invention convenient to use. When applying this invention, the welding auxiliary device is used on one side of the welding robot, and the rotating frame facilitates the clamping of the pad and the iron seat. A support frame 200 is set on the base plate 100 to support the pad 400. A positioning frame 300 is located above the support frame 200. Specifically, the support frame 200 is located above the pad 400, and the positioning frame 300 has multiple positioning areas to position the iron seats 500 on multiple pads 400 at once. Limiting components 600 are respectively provided at both ends of the support frame 200 to limit the positioning frame 300. Figure 3 As shown, a rotating handle 800 is fixedly connected to one end of the base plate 100. The rotating handle 800 is an arc shape formed by pressing steel pipe. Specifically, the rotating handle 800 is welded to one end of the base plate or one end of the bracket under the base plate 100. The rotating handle 800 facilitates the rotation of the base plate 100, improving the ease of use of this welding auxiliary device. Of course, in other embodiments, the rotary table can also be a motor-driven electric rotary table. The electric rotary table adopts the existing electrically driven rotatable worktable, and its structure is not specifically limited here.
[0025] When using the turnout pad welding auxiliary device of this utility model, multiple pads 400 are placed on the support frame 300 according to requirements. Then, the positioning frame 300 is placed above the pad 200. The two ends of the positioning frame 500 are respectively limited by the limiting components 600. Then, the iron seat 500 is placed in the positioning area of the positioning frame 500 for positioning. After positioning, the positioning frame 300 is removed, and the base plate 100 is rotated 180 degrees so that the pad 400 and the iron seat 500 are close to the welding robot for welding. In this embodiment, five pads 400 are placed on the support frame 300, and five pads are processed at once, improving processing efficiency.
[0026] See Figure 2The support frame 200 in this embodiment includes support rods 210, with two support rods 210 arranged in parallel and spaced apart. The support rods 210 are made of steel pipe, and the top surface of the pipe, i.e., the contact surface with the pad, needs to be precision machined to ensure its flatness. The use of two parallel support rods facilitates ensuring the flatness of the support frame, and the structure is simple and easy to manufacture. In other embodiments, the support rods 210 can be replaced with multiple support bases, as long as they can stably support the pad; no specific structural limitations are specified here.
[0027] See Figure 1 The positioning frame 300 in this embodiment includes a fixed frame 310 and positioning rods 320. The fixed frame 310 is a rectangular frame structure in which two parallel vertical rods 311 and a horizontal rod 312 fixed to both ends of the vertical rods 311 are fixedly connected by welding. In order to reduce the weight of the positioning frame 300, improve its ease of use, and reduce manufacturing costs, the vertical rods 311, the horizontal rods 312, and the positioning rods 320 are all steel pipes. The positioning rods 320 are arranged at intervals and parallel to the horizontal rods 312. Both ends of each positioning rod 320 are fixedly connected to the vertical rods 311. In this embodiment, the positioning rods 320 are connected to the vertical rods 311 by welding. In other embodiments, the positioning rods 320 can also be connected to the vertical rods 311 by bolts. The positioning rod 320 and the inner side of the longitudinal beam 311 form a positioning area. In use, the positioning frame 300 is placed on the pad 400 and limited by the limiting component 600. The bottom surface of the longitudinal rod 311 is pressed against the top surface of the pad 400. In this embodiment, there is a gap between the bottom surface of the rod 320 and the top surface of the pad 400, that is, the two do not contact each other. The iron seat 500 is set in the limiting area, and its corresponding side and end face contact the side of the positioning rod 320 and the inner side of the longitudinal beam 311.
[0028] An auxiliary positioning rod 330 is fixedly connected to one end of the support frame 300. Specifically, the auxiliary positioning rod 330 is fixed to one of the crossbars 312, and the length of the auxiliary positioning rod 330 is less than the length of the crossbar 312. The auxiliary positioning rod 330 is provided to facilitate its use in conjunction with the limiting component 600. In use, the bottom surface of the auxiliary positioning rod 330 is pressed against the limiting component 600.
[0029] See Figure 2 and Figure 3The limiting component in this embodiment includes a limiting post 610 and a limiting rod 620. The limiting post 610 is fixedly disposed at one end of the support frame 200 and is arranged vertically. The limiting rod 620 is horizontally disposed at the other end of the support frame 200. The limiting rod 620 is located at the top of a vertically arranged fixed rod 640, and is threadedly connected to the fixed rod 640 to form a threaded pair, allowing the limiting rod 620 to reciprocate horizontally. To facilitate adjustment of the limiting rod 620, in this embodiment, the limiting rod 620 is a screw, with one end abutting against the side of the positioning frame 300, and the other end having a handle 650. Adjustment of the limiting rod can be achieved by rotating the handle, making it convenient to use. In other embodiments, the limiting rod 620 is a wing bolt.
[0030] In this embodiment, see Figure 1 and Figure 2 Both the limiting post 610 and the limiting rod 620 are connected to the base plate 100 via fixing plates 630. Specifically, the limiting post 610 is fixed to the corresponding fixing plate 630 by welding. Both fixing plates 630 are fixed to the base plate 100 by welding. In use, the auxiliary positioning rod 330 is pressed against the fixing plate 630. There are multiple limiting posts 610. One limiting post 610 is in contact with the side of the auxiliary positioning rod 330 of the positioning frame 300. The remaining limiting posts 610 are arranged in a straight line and are in contact with the end face of the auxiliary positioning rod 330 of the positioning frame 300 to perform longitudinal and lateral positioning of the positioning frame 300. To use, place five pads 400 on the support rod 210 as required, then place the positioning frame 300 on the pads 400. The side of the auxiliary positioning rod 330 should be in contact with one of the limiting rods 610, and its end face should be in contact with the remaining limiting rods 610. The other side of the positioning frame 300 should also abut against the limiting rod 620, thus completing the positioning of the positioning frame 300. Next, place the iron seat 500 on the pads 400, ensuring that the outer end face of the iron seat 500 is in contact with the side of the longitudinal rod 311, and that the side of the iron seat 500 is in contact with the side of the positioning rod 320, thus completing the positioning of the iron seat 500. This method eliminates the need for marking lines, is convenient to use, and allows for the positioning of multiple pads at once, improving the efficiency of pad welding.
[0031] See Figure 3The turnout pad welding auxiliary device of this embodiment also includes a positioning component 900, which is a spacer block (not shown in the figure) placed on the base plate 100. In use, the working surface of the spacer block contacts the side of one side of the support frame 200 to position the pad 400. The spacer block is an iron block distributed on the outer side of the two crossbars 210. During use, the spacer block can be positioned as required to position the pad 400. Each time it is used, the side of the spacer block is pressed against the side of the pad 400, and then another pad 400 is placed to prevent the side of the pad 400 from pressing against the other side of the spacer block, making it convenient to use. Alternatively, multiple spacer blocks can be fixed to the base plate with bolts.
[0032] As another preferred embodiment of this utility model, see Figure 3 The positioning element 900 consists of multiple spaced positioning plates 910 disposed on the base plate 100 or on the support frame 200. In this case, the width of the positioning rod 320 of the positioning frame 300 is smaller than the width of the positioning plate 910 to prevent interference between the positioning rod 320 and the positioning plate 910. The positioning plate 910 is welded to the base plate 100.
[0033] In other embodiments of this utility model (not shown in the figure), the positioning member 900 is a plurality of spaced positioning grooves provided on the top surface of the support frame 200, or a positioning line provided on the top surface of the support frame 200.
[0034] Example 2: This example adds a support frame to the existing example. When welding a pad on another support frame, the operator places the pad on the other support frame and positions the iron base, improving processing efficiency. The specific structure is as follows: See [link to example]. Figure 1 and Figure 3 Two support frames 200 are provided on the base plate 100, symmetrically arranged around the center point of the base plate 100. A vertically arranged partition 700 is provided between the two support frames 200 and fixed to the base plate 100. To improve the stability of the partition 700, connecting seats 710 are provided on both sides of the bottom of the partition 700 and fixedly connected to it. The connecting seats 710 are welded to the base 100.
[0035] When using the turnout pad welding auxiliary device of this embodiment, the partition plate 700 is located at the entrance of the welding room, with one side of the partition plate 700 inside the welding room and the other side outside the welding room. A welding robot is installed inside the welding room. During operation, welding is performed on one side while the pad plate 400 and iron seat 500 are installed on the other side. After welding is completed, the base plate 100 is rotated to allow the other side to rotate into the welding room for welding on the other side. This allows welding to proceed continuously and improves welding efficiency. The partition plate 700 can block welding slag from splashing, ensuring safety during use. The structural design is simple, reasonable, and highly practical.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
