Description

Technical Field

[0001] This utility model relates to a tray, and more specifically, to an engine testing tray. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy. After assembly, an engine needs to undergo a series of tests before it can leave the factory or be installed in automobiles or other equipment. Current testing methods mostly involve fixing the engine in a testing device for testing. However, the performance that this testing device can detect is limited. When other performance aspects of the engine need to be tested, it must be transported to another testing device for further testing.

[0003] Because the engine itself is heavy, it is time-consuming and labor-intensive to transport. To solve this problem, existing methods combine several testing devices into a production line and use the transport device on the line to transport the engine. However, when the engine is transported from one station to another, different performance tests require different wiring connections. There are connection points all around the engine, and wiring is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0024] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] An engine testing tray, such as Figures 1-6 As shown, the device includes a tray body 1 and a connecting plate 4. The connecting plate 4 is provided with several probes or connectors that are electrically connected to the testing equipment. A limiting module is provided on one side of the top of the tray body 1. The connecting plate 4 is detachably connected to the limiting module in the vertical direction. By setting the limiting module, the connecting plate 4 can be detachably connected to the limiting module, making it easier to replace the connecting plate 4. This enables the testing of different engine performances and expands the applicability of the overall tray.

[0026] The top of the tray body 1 is equipped with three support columns 2 for lifting the engine. The height of the support column near the limiting module is greater than the height of the limiting module. By setting the support columns 2, the engine can be lifted, creating a gap between the engine and the tray body 1, which facilitates wiring and prevents the engine from blocking the limiting module after being placed on the support columns 2, thus affecting the installation and removal of the plug plate 4. The top of the support column 2 is equipped with a positioning protrusion 21 that matches the engine hole. By setting the positioning protrusion 21, after the engine is placed on the top of the support column 2, the positioning protrusion 21 is inserted into the corresponding hole, thereby limiting the horizontal displacement of the engine and making the placement more stable. There are three support columns 2, forming a triangle, which makes the support more stable. Wire clamps can be installed on the outer peripheral wall of the support column 2. The support columns 2 can also be used to raise the wire clamps, making wiring more convenient and neater.

[0027] The limiting module includes a fixed plate 5, limiting members 51 symmetrically arranged on the top of the fixed plate 5 along its length, a baffle detachably connected to one side of the limiting member 51, and a snap-fit ​​assembly. The fixed plate 5 is fixedly connected to the top of the tray body 1 by bolts. There is a gap between adjacent limiting members 51. The cross-section of the limiting member 51 is U-shaped and vertically arranged on the top of the fixed plate 5. The openings of two adjacent limiting members 51 face each other, so that a sliding groove 511 is formed on the side of the two limiting members 51 facing each other. The top of the groove 511 is open, and a sliding cavity is formed between the two grooves 511. The insertion plate 4 is inserted into the groove 511 in the vertical direction. The setting of the limiting member 51 restricts the horizontal displacement of the insertion plate 4. The snap-fit ​​assembly is used to restrict the insertion plate 4 from disengaging from the groove 511 in the vertical direction, thereby completing the fixation of the insertion plate 4. The limiting member 51 includes a limiting part with an L-shaped cross section integrally formed on the top of the fixing plate 5 and a baffle detachably connected to one side of the limiting part. The groove 511 is surrounded by the baffle and the limiting part.

[0028] The snap-fit ​​assembly includes a plug 6 disposed on the side of the limiting member 51 facing the baffle and an elastic member 611 disposed on the limiting member 51. A blind hole 42 is provided on one side of the insert plate 4 for the plug 6 to be inserted. The elastic member 611 is used to drive the plug 6 to insert into the blind hole 42 by elastic deformation potential energy. A through hole 512 is provided on the inner bottom wall of the slide groove 511, i.e., the limiting part, for the plug 6 to pass through. A sleeve 61 communicating with the through hole 512 is fixedly connected to the outer side of the limiting member 51. The elastic member 611 is disposed in the sleeve 61. A pull rod 62 is fixedly connected to the end of the plug 6 facing away from the insert plate 4. The pull rod 62 passes through the sleeve 61. The elastic member 611 is a spring. The elastic member 611 is disposed in the sleeve 61 and sleeved on the outer peripheral wall of the pull rod 62. A protrusion with a large cross-section is fixedly connected to one end of the slide groove 511. The pull rod 62 is fixed in the middle of the side of the protrusion away from the plug-in 6. One end of the elastic element 611 is set on the inner bottom wall of the sleeve 61, and the other end of the elastic element 611 abuts against the protrusion of the plug-in 6. The end of the pull rod 62 away from the plug-in 6 passes through the sleeve 61 and is fixedly connected to the grip 63. The diameter of the grip 63 is larger than the diameter of the sleeve 61. By setting the grip 63, the contact area is increased, making it easier to pull the pull rod 62. The grip 63 also has a certain limiting function to prevent the pull rod 62 from detaching from the sleeve 61. A handle 41 is fixedly connected to one side of the plug plate 4, which extends vertically out of the slide groove 511. The handle 41 makes it easier to pick up the plug plate 4.

[0029] The bottom of the pallet body 1 is provided with a base plate 3, and the two sides of the base plate 3 are provided with symmetrically arranged slots 31. Rollers 32 are rotatably connected in the slots 31, and the outer peripheral wall of the rollers 32 protrudes from the slots 31. By setting the rollers 32, the whole pallet can operate better on the production line, and the stress wear on the track on the production line can be reduced, thereby improving the service life. A docking part for fixing to the drive equipment can also be detachably connected to one side of the pallet body 1. The drive equipment used to drive the pallet body to move on the production line can be fixed to the docking part to prevent direct docking with the pallet body 1, which would affect the service life of the pallet body 1.

[0030] Working principle: Pulling the grip 63 moves the lever 62, causing the end of the connector 6 to extend into the through hole 512. At this time, the elastic element 611 deforms under external force, inserting the connector 4 vertically between the two limiting elements 51, with both side walls contacting the bottom wall of the slide groove 511. After full insertion, the lever 62 is released, and the elastic element 611 is no longer affected by external force. Through its own elastic reset, the connector 6 is inserted into the blind hole 42 on one side of the connector 4, thereby restricting the connector 4 from disengaging from the slide groove 511 vertically, thus completing the fixation of the connector 4. The engine is placed on top of the three support columns 2, and the positioning protrusion 21 on the top of the support column 2 is inserted into the corresponding hole, thereby restricting the horizontal displacement of the engine. When the pallet body 1 moves, it prevents the engine from shaking and ensures the stability of transportation.

[0031] After the engine is placed, the wiring of the plug plate 4 and the engine is completed at the first test station on the production line. After the wiring is completed, the test is performed. After the test is completed, the pallet body 1 is transported through the production line to the next test station. At this time, pulling the grip part 63 causes the pull rod 62 to move, which drives the end of the plug 6 to extend into the through hole 512. The plug plate 4 can then be easily removed from the limiting module, and a plug plate 4 with another test probe or wire harness can be inserted into the limiting module. The operation is more convenient, saves time and effort, and improves work efficiency. Moreover, with the plug plate 4, it is not necessary to install all probes or wire harnesses on the pallet body 1, which reduces the space occupied, reduces costs, and makes the operation more convenient.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
