Description

Technical Field

[0001] This utility model relates to a universal positioning device for automated welding of the rear frame of a forklift, belonging to the field of forklift tooling. Background Technology

[0002] In the forklift industry, the rear frame is used in the forklift chassis system, primarily for mounting the steering axle, radiator, muffler, counterweight, etc., and its structure is as follows: Figure 7 As shown, it includes a rear tailplate 6, a support plate 7, a V-shaped plate 8, and side plates 9. The forklift rear frame connects to the fuel tanks and hydraulic oil tanks on both sides, forming a complete load-bearing frame that plays a crucial role in the forklift's structural strength, stable and efficient operation, and prevention of tipping over during turns. Due to the wide variety of forklift types, and even within the same type of forklift with different tonnages, the rear frames of different models vary. Therefore, when automating the welding of the rear frame in the workshop to improve production efficiency, a positioning device must be made for each model.

[0003] This approach results in significant waste, increases product manufacturing costs and the space occupied by multiple positioning devices. Furthermore, frequent hoisting and switching of positioning devices is required when producing different vehicle models, reducing work efficiency, increasing labor intensity, and impacting the control of product production cycles. Summary of the Invention

[0004] The problem to be solved by this utility model is to provide a universal positioning device for the rear frame of forklifts that improves the automated welding efficiency of the rear frame of multi-model forklifts and reduces manufacturing costs and labor intensity.

[0005] To solve the above problems, the technical solution of this utility model is to provide a universal positioning device for automated welding of forklift rear frame, which includes a base, a plurality of pressure blocks for positioning side plates, a positioning block for positioning side plates, and a support seat for supporting support plates.

[0006] Preferably, the base includes a base plate, and the bottom of the base plate is provided with a frame structure composed of multiple rectangular tubes, and the bottom of the frame structure is provided with a mounting plate for fixing the base.

[0007] More preferably, the mounting plate has a through hole, which is connected to an external rotating platform by bolts.

[0008] More preferably, the rectangular tube is provided with end-sealing plates at both ends for sealing.

[0009] Preferably, the base is provided with a plurality of connection holes for connecting the pressure block, the positioning block, and the support base.

[0010] Preferably, the support base includes a bottom connecting plate and a vertical plate disposed on the bottom connecting plate.

[0011] The bottom connecting plate is welded to the vertical plate.

[0012] More preferably, the vertical plate is provided with a pad for limiting the rear frame of the forklift.

[0013] Furthermore, the vertical plate is provided with multiple threaded holes for connecting a pad plate, which is connected to the vertical plate by screws. The pad plate is used to laterally clamp the workpiece to prevent it from moving during the welding process.

[0014] This utility model provides a positioning platform that can accommodate the rear frames of multiple vehicle models, enabling all weld seams to be welded during the automated welding process of the rear frame, and allowing for rapid switching and improved efficiency.

[0015] The beneficial effects of this utility model are as follows: through the cooperation between various mechanisms and parts, the rear frames of different models of forklifts can be quickly placed, positioned and clamped, which improves the efficiency of automated welding of the rear frame, saves time and effort, and enables the production of the forklift rear frame to proceed better and faster, ensuring that the product is completed in a timely manner within the production cycle.

Detailed Implementation

[0023] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0024] Example

[0025] like Figure 1 As shown, this utility model provides a universal positioning device for automated welding of forklift rear frames, which includes a base 1, and a plurality of pressure blocks 2 for positioning side plates 9 are provided on the base 1. Figure 3 As shown), positioning block 3 for positioning side plate 9 ( Figure 4 (as shown), support base 4 for supporting support plate 7.

[0026] like Figure 2 As shown, the base 1 includes a base plate 1-1. The bottom of the base plate 1-1 has a frame structure composed of multiple rectangular tubes 1-2. At the bottom of this frame structure is a mounting plate 1-4 for fixing the base 1. The mounting plate 1-4 has through holes, which are connected to an external rotating platform via bolts. Both ends of the rectangular tubes 1-2 have end-sealing plates 1-3. The base 1 has multiple connecting holes for connecting the pressure block 2, the positioning block 3, and the support base 4.

[0027] like Figure 5 As shown, the support base 4 includes a bottom connecting plate 4-1 and a vertical plate 4-2 disposed on the bottom connecting plate 4-1. The bottom connecting plate 4-1 and the vertical plate 4-2 are welded together. The vertical plate 4-2 is provided with a pad 5 for limiting the rear frame of the forklift, such as... Figure 6 As shown. The vertical plate 4-2 is provided with multiple threaded holes for connecting the pad 5, and the pad 5 is connected to the vertical plate 4-2 by screws.

[0028] The main components of the above-mentioned device include:

[0029] The base (made of a base plate, multiple rectangular tubes, a sealing plate and a mounting plate welded together) serves as an installation platform. All other components are directly or indirectly mounted on this platform. The mounting plate has a ring of mounting holes and can be connected to an external rotating platform by screws.

[0030] Pressure blocks (strip-shaped parts with waist-shaped grooves and steps), several pressure blocks work together to clamp the workpiece;

[0031] A positioning block (a circular part with a countersunk hole in the center) is used to position several surfaces of a workpiece when it is placed.

[0032] The support base (made of a bottom connecting plate and a vertical plate welded together) has through holes in the bottom connecting plate and several threaded holes in the vertical plate to facilitate installation on different vehicle models. It provides lateral support and positioning for the workpiece.

[0033] The pad (a circular part with a central hole) is mounted on the support base with screws to clamp the workpiece laterally, and works with the pressure block to fix the workpiece.

[0034] The usage process of the above device is as follows:

[0035] First, install the positioning blocks and pressure blocks in the corresponding positions according to the vehicle model to be used. Hoist the pre-welded rear frame onto the base. Make sure the side panels of the rear frame are close to the positioning blocks (in this embodiment, there are three locations: one on the rear end face of side panel 9 and two on the lower end face). Use screws through the pads and the process holes of the rear frame to make the support plate of the rear frame adhere to the support seat. Use the pads to press the support plate of the rear frame firmly. Adjust the pressure blocks to the appropriate position and press the side panels of the rear frame against the base plate. After positioning and clamping are completed, the automated welding of the rear frame can begin. After completion, if it is necessary to change the vehicle model, simply adjust the installation position of the positioning blocks and pressure blocks and then repeat the above steps.
