Description

Technical Field

[0001] The present application relates to the field of parts processing tooling, and in particular to a bridge tooling for an electric tractor. Background Art

[0002] An electric tractor is a traction vehicle that uses electricity as a power source. It is usually used in cargo transportation, logistics warehousing and other scenarios, and moves and transports cargo by towing trailers or trucks. Compared with traditional fuel tractors, electric tractors have the advantages of zero emissions, low noise, and low energy consumption, and are more in line with environmental protection and energy-saving requirements.

[0003] At present, most of the bridge frames of electric traction vehicles are still mainly welded by hand. Since each worker has a different technique, there are slight errors in the size of the vehicle bridge frame after each welding, making it difficult to achieve precise size control. Inspectors are required to manually measure the on-site values ​​each time. Therefore, the welding efficiency is not high, and the quality of the product is difficult to guarantee, which is an obvious shortcoming. Utility Model Content

[0004] In order to improve the problems of large welding errors and low welding efficiency, the present application provides a bridge frame tooling for an electric tractor.

[0005] The present application provides a bridge tooling for an electric tractor using the following technical solution:

[0006] A bridge frame tooling for an electric tractor comprises a component body, a plurality of positioning members are arranged on the component body, the positioning members comprise positioning pins slidably penetrated on the component body, and positioning holes are provided on the bridge frame for plugging and cooperating with the positioning pins.

[0007] By adopting the above technical solution, positioning holes are opened on the frame, and the positioning pins on the component body are plugged into the plug holes. Since the positioning pins are accurately positioned on the component body, the various parts of the bridge frame can be accurately positioned, thereby improving the welding quality and welding efficiency.

[0008] Optionally, the positioning member includes a door-shaped support frame arranged on the component body, the positioning pin slides through the support frame, a top support ring is fixed on the positioning pin, and a compression spring is provided between the support frame and the side of the positioning pin opposite to the top support ring facing away from the bridge frame.

[0009] By adopting the above technical solution, when the positioning pin and the positioning hole are aligned, the worker loosens the positioning pin, and the deformation force of the compression spring acting on the top support ring pushes the positioning pin into the positioning hole. When welding is completed, the worker manually pulls the positioning pin out of the positioning hole again.

[0010] Optionally, the positioning pin is rotatably matched with the supporting frame, and two locking rods extending away from the bridge frame are arranged on the top support ring, one of which is supported on the side of the supporting frame facing the frame body, and the other locking rod is bent after passing through the supporting frame and is supported on the side of the supporting frame facing away from the component body. The supporting frame is provided with a clearance groove for giving way to the locking rods.

[0011] By adopting the above technical solution, the worker manually rotates the locating pin, and the top support ring on the locating pin drives the two locking rods to rotate synchronously. One locking rod supports the supporting frame toward one side of the frame body, and the other locking rod rotates into the clearance groove and supports the supporting frame toward the side of the component body. The two locking rods cooperate to keep the locating pin and the locating hole in an inserted state, reducing the possibility of the locating pin accidentally detaching from the locating hole.

[0012] Optionally, an elastic pressing sheet is arranged on the carrier, and the elastic pressing sheet extends into the clearance groove and presses the locking rod against the side wall of the clearance groove.

[0013] By adopting the above technical solution, when the lock rod rotates into the give way groove, the elastic pressing piece is deformed by force, and the deformation force acts in the opposite direction on the lock rod, thereby pressing the lock rod against the side wall of the give way groove, reducing the possibility of the lock rod accidentally and automatically detaching from the give way groove.

[0014] Optionally, the cross-section of the support frame at the location where the positioning pin is inserted is hourglass-shaped.

[0015] By adopting the above technical solution, the contact area between the carrier and the positioning pin is reduced, and the smoothness of the sliding of the positioning pin on the carrier is improved.

[0016] Optionally, the positioning pin includes a positioning rod and a positioning head threadedly connected to the positioning rod.

[0017] By adopting the above technical solution, since the locating hole is not only used for the connection with the locating pin during the welding process, but will also be used for the subsequent installation with the tractor, the apertures of the locating holes may not be the same. Workers can replace locating heads of different sizes and diameters on the locating rod according to actual conditions to adapt to the connection of locating holes of different diameters.

[0018] Optionally, a fixing sleeve on the positioning head is provided with a torsion block having an elliptical cross-section.

[0019] By adopting the above technical solution, the setting of the twist block makes it convenient for workers to rotate the positioning head, thereby reducing the possibility of slipping between the hand and the positioning head.

[0020] Optionally, a pull ring is arranged at the other end of the positioning pin opposite to the positioning hole.

[0021] By adopting the above technical solution, the provision of the pull ring makes it convenient for workers to manually pull out the positioning pin.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Open a positioning hole on the frame, and plug the positioning pin on the component body into the plug hole. Since the positioning pin is accurately positioned on the component body, each part of the bridge can be accurately positioned, thereby improving the welding quality and welding efficiency;

[0024] 2. When the locating pin and the locating hole are aligned, the worker loosens the locating pin, and the deformation force of the compression spring on the top support ring pushes the locating pin into the locating hole. When welding is completed, the worker manually pulls the locating pin out of the locating hole again;

[0025] 3. Since the locating holes are not only used for the connection with the locating pins during the welding process, but will also be used for the subsequent installation with the tractor, the apertures of the locating holes may not be the same. Workers can replace locating heads of different sizes and diameters on the locating rods according to actual conditions to adapt to the connection with locating holes of different diameters.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a bridge frame tooling for an electric tractor.

[0032] Reference Figure 1 and Figure 2 The bridge tooling for the electric tractor includes a component body 1, which is welded from three modules, and each module is welded from multiple pipes.

[0033] A plurality of positioning members 2 are arranged on the component body 1. The positioning members 2 include a door-shaped support frame 22 bolted to the component body 1. The support frame 22 is provided with positioning pins that can slide and rotate. The positioning pins pass through the component body 1. The bridge frame also has positioning holes for plugging and cooperating with the positioning pins.

[0034] Reference Figure 2 and Figure 3 The cross section of the portion on the carrier 22 where the positioning pin is inserted is hourglass-shaped, thereby reducing the contact area between the carrier 22 and the positioning pin, thereby improving the smoothness of the sliding and rotation of the positioning pin on the carrier 22.

[0035] Reference Figure 2 and Figure 3 Since the locating holes are used to mate with the locating pins during the welding process and will be subsequently used for assembly with the tractor, the apertures of the locating holes at different positions are different.

[0036] To this end, the positioning pin is divided into a positioning rod 211 and a positioning head 212. The positioning head 212 is threadedly connected to the positioning rod 211. The positioning head 212 is used to be inserted into the fixed hole. Workers can replace the model of the positioning head 212 on the positioning rod 211 according to the aperture of the positioning hole.

[0037] Reference Figure 2 and Figure 3 The positioning head 212 is integrally formed with a twist block 3 having an elliptical cross section. The twist block 3 facilitates workers to unscrew the positioning head 212 from the positioning rod 211, thereby reducing the possibility of slipping between the hands and the positioning head 212.

[0038] Reference Figure 2 and Figure 3 A top support ring 23 is fixedly sleeved on the positioning rod 211, and a compression spring 24 is provided between the side of the positioning rod 211 facing away from the bridge frame and the carrier frame 22. When the positioning pin is aligned with the positioning hole, the deformation force of the compression spring 24 on the top support ring 23 pushes the positioning head 212 into the positioning hole.

[0039] Reference Figure 2 and Figure 3 Two locking rods 25 are welded on the side of the top support ring 23 facing away from the bridge frame. Both locking rods 25 extend in the direction away from the bridge frame. One of the locking rods 25 is supported on the side of the supporting frame 22 facing the frame body, and the other locking rod 25 is bent into an L shape after passing through the supporting frame 22 and is supported on the side of the supporting frame 22 facing away from the component body 1. The supporting frame 22 is provided with an arc-shaped making way groove 221 for making way for the locking rod 25.

[0040] Reference Figure 2 and Figure 3After the locating pin is inserted into the locating hole, the worker manually rotates the locating pin, and the supporting ring 23 on the locating pin drives the two locking rods 25 to rotate synchronously. One locking rod 25 supports the supporting frame 22 toward the side of the frame body, and the other locking rod 25 rotates into the clearance groove 221 and supports the supporting frame 22 to the side away from the component body 1. In this way, the two locking rods 25 cooperate to keep the locating pin and the locating hole in the plug-in state, reducing the possibility of the locating pin accidentally detaching from the locating hole.

[0041] Reference Figure 2 and Figure 3 An elastic pressing piece 26 made of elastic metal is riveted on the carrier frame 22 . The elastic pressing piece 26 extends into the clearance groove 221 and is used to press the locking rod 25 against the side wall of the clearance groove 221 .

[0042] When the locking rod 25 rotates into the clearance groove 221, the elastic pressing piece 26 is deformed by the force, and the deformation force acts in the opposite direction on the locking rod 25, thereby pressing the locking rod 25 against the side wall of the clearance groove 221, reducing the possibility of the locking rod 25 accidentally detaching from the clearance groove 221.

[0043] Reference Figure 2 and Figure 3 A pull ring 4 is welded on the other end of the positioning pin that is inserted into the positioning hole. The setting of the pull ring 4 makes it convenient for workers to manually push and pull the positioning pin.

[0044] The implementation principle of the bridge tooling for electric tractors in the embodiment of the present application is as follows: when the positioning pin and the positioning hole are aligned, the worker loosens the positioning pin, and the deformation force of the compression spring 24 acting on the top support ring 23 pushes the positioning pin into the positioning hole. After that, the worker manually rotates the positioning pin, and the top support ring 23 on the positioning pin drives the two locking rods 25 to rotate synchronously, one locking rod 25 supports the supporting frame 22 toward one side of the frame body, and the other locking rod 25 rotates into the clearance groove 221 and supports the supporting frame 22 away from the side of the component body 1, so that the two locking rods 25 cooperate to keep the positioning pin and the positioning hole in the plug-in state.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
