Description

Technical Field

[0001] This utility model belongs to the field of connecting rod welding technology, and specifically relates to a connecting rod tooling. Background Technology

[0002] In civil defense structures, in order to make it easier to pull the civil defense door, a locking link is usually installed on the civil defense door. However, the locking link of the civil defense door is not a straight rod, but is made up of multiple sections connected together. When connecting multiple sections, they are usually positioned manually and then welded. This means that positioning two sections requires two times, and multiple sections require even more positioning, which takes a lot of time. Moreover, the accuracy of manual positioning cannot be guaranteed, which may affect the final welding quality. Utility Model Content

[0003] The purpose of this invention is to provide a connecting rod tooling to solve the problems of low efficiency and unreliable quality in manual welding of locking connecting rods in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A linkage fixture includes two columns and a linkage cradle backplate rotatably connected between the two columns. A drive motor for driving the linkage cradle backplate to rotate is mounted on one of the columns. A plurality of linkage positioning mechanisms distributed along the length direction are mounted on one side of the linkage cradle backplate. Each linkage positioning mechanism includes a linkage support seat and a linkage positioning cylinder correspondingly mounted on one side of the linkage cradle backplate. Each section of the locking linkage is supported on at least one linkage support seat. The telescopic rod of the linkage positioning cylinder abuts against the side of the locking linkage away from the linkage support seat.

[0006] As a preferred technical solution of this utility model, each connecting rod positioning cylinder is mounted on a cylinder connecting plate. The end of the cylinder connecting plate near the connecting rod cradle back plate is connected to the end of the connecting rod support seat near the connecting rod cradle back plate via a longitudinal channel steel. The longitudinal channel steel is connected to the connecting rod cradle back plate via a first bolt.

[0007] As a preferred technical solution of this utility model, two first elongated holes extending in the vertical direction are opened on the longitudinal channel steel. At least one first bolt is correspondingly provided in each elongated hole, and the threaded part of the first bolt passes through the first elongated hole and is threadedly connected to the back plate of the connecting rod cradle. The nut of the first bolt abuts against the longitudinal channel steel.

[0008] As a preferred technical solution of this utility model, one side of the back plate of the connecting rod cradle is provided with a slide rail extending along its length direction. Multiple sliders are slidably connected on the slide rail, and slider connecting plates are fixed on the sliders. Each longitudinal channel steel is connected to a slider connecting plate by a first bolt. A bayonet rocker arm is rotatably connected to the upper end of each slider connecting plate. Multiple slots distributed along its length direction are opened at the upper end of the back plate of the connecting rod cradle, and each bayonet rocker arm is matched and engaged in a slot.

[0009] As a preferred technical solution of this utility model, the slide rails are provided in two parallel positions, each slider connecting plate is connected to the two sliders, and the two sliders are slidably connected to the two slide rails respectively.

[0010] As a preferred technical solution of this utility model, a square telescopic bellows-style protective cover is installed between any two adjacent linkage positioning mechanisms, covering the slide rail. The two ends of the square telescopic bellows-style protective cover are connected to the slider.

[0011] As a preferred technical solution of this utility model, both ends of the connecting rod cradle back plate are vertically connected to connecting end plates, and both connecting end plates are connected to rotating shafts. Both rotating shafts are rotatably connected to the upper part of the corresponding column through bearings, and one of the rotating shafts is connected to the motor shaft of the drive motor.

[0012] As a preferred technical solution of this utility model, a positioning sleeve is installed at the end of a connecting end plate away from the back plate of the cradle, and a pin is installed on the upper part of the column corresponding to the positioning sleeve, with one end of the pin being matched and inserted into the positioning sleeve.

[0013] Beneficial effects: In use, this utility model allows all components of the locking link to be positioned and clamped between the link support seat and the link positioning cylinder of the link fixture. During positioning and clamping, each component is positioned by at least one link positioning mechanism, while the part to be welded is located between two link positioning mechanisms, leaving space for welding. In this way, the positioning of the entire locking link can be achieved through the synchronous action of multiple link positioning cylinders. Welding can be performed directly on one side of the locking link for all components. After one side is welded, the drive motor drives the link cradle back plate to flip, so that the other side of the locking link is facing upwards, thus facilitating welding of all components on the other side of the locking link. The entire process can be positioned in one go, enabling rapid welding of the locking link. Moreover, the cooperation between the link support seat and the link positioning cylinder ensures positioning accuracy, thereby avoiding the impact of the instability of manual positioning on the welding quality.

Detailed Implementation

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0018] Example:

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a linkage fixture, including two columns 1 and a linkage cradle back plate 2 rotatably connected between the two columns 1. A drive motor 3 for driving the linkage cradle back plate 2 to rotate is installed on one of the columns 1. Multiple linkage positioning mechanisms distributed along the length direction are installed on one side of the linkage cradle back plate 2. The spacing between adjacent linkage positioning mechanisms can be set according to the actual situation and is not specifically limited. Each linkage positioning mechanism includes a linkage support seat 4 and a linkage positioning cylinder 5 correspondingly installed on one side of the linkage cradle back plate 2. Each section of the locking linkage 6 is supported on at least one linkage support seat 4. The telescopic rod of the linkage positioning cylinder 5 abuts against the side of the locking linkage 6 away from the linkage support seat 4, so that each section of the locking linkage 6 is positioned by at least one linkage positioning mechanism. The part that needs to be welded, that is, the part where every two sections are connected, is located between two linkage positioning mechanisms, so as to leave space for welding. It should be noted that the locking link 6 is clamped by the linkage support 4 and the linkage positioning cylinder 5. In practice, the distance between each linkage support 4 and the linkage positioning cylinder 5 can be adjusted in advance. Then, when the linkage positioning cylinder 5 is activated, all the telescopic rods can simultaneously abut against the locking link 6, thereby achieving the positioning and clamping of the locking link 6 more efficiently.

[0020] In use, this invention allows all components of the locking link 6 to be positioned and clamped between the link support 4 and the link positioning cylinder 5 of the link fixture. During positioning and clamping, each component is positioned by at least one link positioning mechanism, while the part to be welded is located between two link positioning mechanisms, leaving space for welding. Thus, the positioning of the entire locking link 6 can be achieved through the synchronous action of multiple link positioning cylinders 5. Welding can be performed directly on one side of the locking link 6 for all components. After one side is welded, the drive motor 3 drives the link cradle back plate 2 to flip, so that the other side of the locking link 6 faces upward, facilitating welding of all components on the other side of the locking link 6. The entire process can be positioned in one step, enabling rapid welding of the locking link 6. Moreover, the cooperation between the link support 4 and the link positioning cylinder 5 ensures positioning accuracy, thus avoiding the impact of the instability of manual positioning on the welding quality.

[0021] As a preferred embodiment of this invention, it should be further explained that each connecting rod positioning cylinder 5 is mounted on a cylinder connecting plate 7. The cylinder connecting plate 7 is arranged parallel to the connecting rod support seat 4. One end of the cylinder connecting plate 7 near the connecting rod cradle back plate 2 is connected to the other end of the connecting rod support seat 4 near the connecting rod cradle back plate 2 via a longitudinal channel steel 8. The cylinder connecting plate 7 is provided with a through hole for easy telescopic rod penetration. The longitudinal channel steel 8 is connected to the connecting rod cradle back plate 2 via a first bolt, thereby realizing the installation of the connecting rod positioning mechanism on the connecting rod cradle back plate 2.

[0022] As a preferred embodiment of this invention, it should be further explained that the longitudinal channel steel 8 has two first elongated holes extending vertically, and each elongated hole is provided with at least one first bolt. The threaded part of the first bolt passes through the first elongated hole and is threadedly connected to the connecting rod cradle back plate 2. The nut of the first bolt abuts against the longitudinal channel steel 8, which facilitates the adjustment of the height of the longitudinal channel steel 8 according to the actual situation, and thus the adjustment of the height of the connecting rod support 4. When the connecting rod support 4 is supported at different positions of the locking connecting rod 6 (some positions have different heights), it ensures that all components of the locking connecting rod 6 can be stably supported on the corresponding connecting rod support 4.

[0023] As a preferred embodiment of this invention, it should be further explained that one side of the connecting rod cradle back plate 2 is provided with a slide rail 9 extending along its length. Multiple sliders 10 are slidably connected to the slide rail 9, and slider connecting plates 11 are fixed to the sliders 10. Each longitudinal channel steel 8 is connected to a slider connecting plate 11 by a first bolt, thus facilitating the appropriate adjustment of the position of the connecting rod positioning mechanism according to actual conditions for clamping and positioning locking connecting rods 6 of different specifications. A bayonet rocker arm 12 is rotatably connected to the upper end of each slider connecting plate 11, connecting rod... The upper end of the cradle back plate 2 has multiple slots 201 distributed along its length. The slots 201 can be pre-designed for multiple models of locking linkages 6. Each locking arm 12 is matched and locked into a slot 201. Then, for the model of the locking linkage 6 to be welded, the locking arm 12 is matched and locked into the slot 201 to realize the positioning of the linkage positioning mechanism and prevent the linkage positioning mechanism from sliding along the slide rail 9. When sliding adjustment is required, it is only necessary to control the locking arm 12 to disengage from the slot 201 for adjustment, which is simple and convenient.

[0024] As a preferred embodiment of this invention, it should be further explained that there are two parallel slide rails 9, and each slider connecting plate 11 is connected to two sliders 10. The two sliders 10 are slidably connected to the two slide rails 9, which makes the connection and sliding of the linkage positioning mechanism on the back plate 2 of the linkage cradle more stable.

[0025] As a preferred embodiment of this invention, it should be further explained that a square telescopic accordion-style protective cover (not shown in the figure) is installed between any two adjacent linkage positioning mechanisms and covers the slide rail 9. The two ends of the square telescopic accordion-style protective cover are connected to the slider 10, which can prevent foreign objects from falling on the slide rail 9 during normal operation and welding, thereby affecting the sliding of the slider 10.

[0026] As a preferred embodiment of this example, it should be further explained that both ends of the connecting rod cradle back plate 2 are vertically connected to connecting end plates 13, and both connecting end plates 13 are connected to rotating shafts. Both rotating shafts are rotatably connected to the upper part of the corresponding column 1 through bearings. One of the rotating shafts is connected to the motor shaft of the drive motor 3, which makes the connecting rod cradle back plate 2 more stably rotatably connected between the two columns 1.

[0027] As a preferred embodiment of this example, it should be further explained that a positioning sleeve is installed at the end of a connecting end plate 13 away from the connecting rod cradle back plate 2. A pin (not shown in the figure) is installed on the upper part of the column 1 corresponding to the positioning sleeve. One end of the pin is matched and inserted into the positioning sleeve. The positioning of the pin can make the connecting rod cradle back plate 2 more stable between the two columns 1, and reduce the stress on the drive motor 3.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
