Description

Technical Field

[0001] This utility model belongs to the field of LFT-D tray technology, and specifically relates to an LFT-D tray welding strength testing device. Background Technology

[0002] The LFT-D pallet molding process involves melting plastic and mixing it with glass fiber to form a blank. A robot then picks up the blank and inserts it into a press for molding. The product is easy to handle and operate, lightweight, high-strength, and impact-resistant. Fiber is added to the matrix for reinforcement, resulting in excellent load-bearing capacity.

[0003] LFT-D pallets are generally divided into types such as Chuanzi, Tianzi, double-sided, and nine-legged. Except for the nine-legged pallet, the other three types of pallets are generally made of a panel and a base plate welded together. The panel is generally equipped with a nine-legged structure, which is welded to the nine-legged structure of the base plate.

[0004] The quality of welding directly affects the stability and safety of pallet use. Currently, the welding quality of LFT-D pallets is generally determined by dropping them from a height or using a jack to lift both ends. However, this method makes it difficult to assess the welding quality and is not conducive to quality inspection during routine production processes. Summary of the Invention

[0009] The pressure testing mechanism is located at one end of the test platform along its length and includes a test plate, a sliding plate, a pressure sensor, a pressure driving component, and a support component disposed between the test plate and the sliding plate. The sliding plate is slidably connected to the support component, enabling it to slide back and forth along the length of the test platform.

[0010] Preferably, the pallet carrying assembly includes carrying fork plates on both sides, which are inserted into the pallet insertion holes to carry the pallet.

Detailed Implementation

[0021] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0022] Example: Figure 1 As shown in the figure, an LFT-D pallet welding strength testing device provided in this embodiment of the present invention includes a testing platform 1, a lifting mechanism, a pallet fixing component, a pressure testing mechanism, and a pallet bearing component disposed on the testing platform 1;

[0023] The pallet-bearing assembly is used to support the pallet and drive the pallet to rise and fall. The pallet-bearing assembly is connected to the lifting mechanism and rises and falls with the lifting mechanism.

[0024] The pallet securing assembly is used to secure the pallet;

[0025] The pressure testing mechanism can be set one-to-one with the bearing fork plate 31. The pressure testing mechanism is set at one end of the test platform 1 along the length direction and includes a test plate 21, a sliding plate 22, a pressure sensor 23, a pressure driving component 24, and a bearing component 25 set between the test plate 21 and the sliding plate 22. The sliding plate 22 is slidably connected to the bearing component 25 so that it can slide back and forth along the length direction of the test platform 1.

[0026] Specifically, the pallet carrying assembly includes two carrying fork plates 31 on both sides, which are inserted into the pallet insertion holes to carry the pallet. The specifications of the carrying fork plates 31 match the pallet fork holes.

[0027] In some embodiments, the carrying fork plate 31 is detachably connected to the lifting mechanism so that it can be replaced, that is, the specifications of the carrying fork plate 31 can be replaced to adapt to pallet testing of different specifications.

[0028] Specifically, the bearing fork plate 31 is detachably connected to the lifting frame 41 of the lifting mechanism via a screw 32. The lifting frame 41 is provided with locking bolts 33 at both ends, which are used to lock the corresponding screw 32 to prevent the screw 32 from rotating.

[0029] Specifically, the lifting mechanism includes a lead screw lifting slide 42 and a lifting frame 41 connected to the slide block of the lead screw lifting slide 42.

[0030] Specifically, the pallet fixing assembly includes several corner cylinders 51 connected to the test platform 1. The corner cylinders 51 are used for direct fixing of the pallet, fixing of the lifting frame 41, or fixing of the bearing fork plate 31, so as to finally fix the pallet.

[0031] Specifically, the sliding plate 22 is slidably connected to the support member 25 via a slide rail. The support member 25 is connected to the movable end of the pressure drive member 24, which is a hydraulic cylinder. The sliding plate 22 is driven to insert into the fork hole of the pallet by sliding the sliding plate 22.

[0032] The testing method of this utility model:

[0033] (1) Install the appropriate load-bearing fork plate 31 on the lifting frame 41;

[0034] (2) The carrying fork plate 31 is inserted into the fork hole of the pallet to be tested. The carrying fork plate 31 carries the pallet and the lifting mechanism is controlled to lower the pallet to be tested onto the test platform 1.

[0035] (3) Secure the test tray using the fixing components;

[0036] (4) Adjust the position of the pressure drive component 24 so that the test plate 21 corresponds to the fork hole of the tray to be tested;

[0037] (5) By sliding the sliding plate 22, part of the test plate 21 is inserted into the fork hole of the pallet to be tested. At this time, the hydraulic cylinder is manually controlled to drive the test plate 21 to lift, simulating the lifting speed and state of the pallet jack. If it is necessary to test two fork holes, the hydraulic cylinder system needs to be linked to achieve the effect of lifting at the same time.

[0038] (6) During the lifting process of test plate 21, pressure sensor 23 continuously collects pressure data and transmits it to the data collection system to display the real-time pressure. When the weld is damaged, the cylinder stops rising. The data collection system can display the maximum pressure.

[0039] (7) After the test is completed, the cylinder returns to its initial position, the test plate 21 slides back to its original position, the fixing component is released, the load-bearing fork plate 31 is lifted, the pallet is unloaded, and the test is completed.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
