Description

Clamping tool for emergency evacuation of battery

Technical Field

The utility model relates to a battery test field, in particular to a centre gripping frock for battery promptly withdraws.

Background

In recent years, a plurality of new energy automobiles enter the automobile market, and the new energy automobiles are mainly driven by pure electric or internal combustion engine power generation. The market is greatly controversial with these new energy vehicles, the most important of which is safety, especially battery safety. The biggest requirement of the design personnel is to find and solve problems in design, test and production. The danger of the battery in research and development tests is larger, because the battery product needs to face various limit tests at this time, especially the latest battery four comprehensive tests (ambient temperature, ambient humidity, road spectrum vibration and road spectrum charging and discharging), the test condition is very close to the limit working condition of actual use, the full life and the limit performance of the product are very challenging, the test danger is very high, the equipment is very expensive, if the battery is accidentally detonated in the test process, tens of millions of equipment with value can be damaged, and if the battery is manually evacuated, the loss of personnel safety can be possibly caused. Therefore, an experimental platform capable of transporting the batteries for evacuation appeared. And when the test, need press from both sides tight test sample, when the conflagration breaks out, can unblock test sample fast.

SUMMERY OF THE UTILITY MODEL

To the defect that prior art exists above, the utility model discloses a main aim at overcomes prior art's weak point, discloses a centre gripping frock for battery promptly withdraws, set up four at least clamping mechanism on test platform including the symmetry, clamping mechanism includes PMKD, fixing support, actuator, compact heap and compact heap support, fixing support with the compact heap support is fixed to be set up on the PMKD, the guide hole that the setting of compact heap support upper level runs through, the compact heap slides and sets up in the guide hole, the actuator sets up on the fixing support, and with the compact heap is connected, utilizes the actuator drive compact heap horizontal migration.

Further, the actuator is a cylinder.

Further, the end of the pressing block is provided with an inclined plane for clamping the test sample.

Further, the included angle between the inclined plane and the test platform is 30-60 degrees.

Further, a rubber layer is adhered to the inclined surface.

Furthermore, four waist-shaped holes are arranged on the fixed bottom plate in an array along the moving direction of the compression block and are fixed with the test platform through screws.

The utility model discloses the beneficial effect who gains:

the utility model realizes the clamping and locking of the test sample through the clamping mechanisms symmetrically arranged at both sides; the oil cylinder drives the pressing block to move horizontally, the end face pressed by the pressing block is an inclined plane, horizontal and vertical forces are applied to the test sample at the same time, and the reliability of clamping the test sample is further improved. Through the rubber layer, the friction force is increased, meanwhile, the test sample is protected, in addition, when the oil cylinder fails, the oil cylinder is in an unpowered state, and the self elasticity of the rubber layer can be utilized, so that the pressing block and the test sample are in a loose state.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A clamping tool for emergency evacuation of batteries comprises at least four clamping mechanisms 2 symmetrically arranged on a test platform 1; the test sample 3 is clamped and fixed by the clamping mechanism 2. Preferably, six clamping mechanisms 2 are provided, and three clamping mechanisms are provided on both sides of the test specimen 3. Specifically, the clamping mechanism 2 comprises a fixed base plate 21, a fixed support 22, an actuator 23, a pressing block 24 and a pressing block support 25, the fixed support 22 and the pressing block support 25 are fixedly arranged on the fixed base plate 21, a through guide hole is horizontally arranged on the pressing block support 25, the pressing block 24 is slidably arranged in the guide hole, and the pressing block 24 is guided to horizontally move through the guide hole. The actuator 23 is fixedly arranged on the fixed support 22 and is connected with the pressing block 24. The actuator 23 may be an oil cylinder, and the oil cylinder pushes the pressing block 24 to move horizontally, so as to clamp and fix the test sample 3.

In one embodiment, the end of the clamping block 24 is provided with a bevel 241 for gripping the test sample. Preferably, the included angle between the inclined plane and the test platform is 30-60 degrees. The test sample 3 is pressed in the horizontal direction and the vertical direction by the inclined surface 241, thereby achieving a locked state.

In one embodiment, the rubber layer 26 is adhered to the inclined surface 241. The friction force with the test sample 3 is increased by the rubber layer; the test specimen 3 is prevented from moving in the axial direction. While preventing damage to the hard fit between the hold down block 24 and the test specimen 3.

In one embodiment, four waist-shaped holes 211 are arranged on the fixing base plate 21 in an array along the moving direction of the pressing block 24, and are fixed with the test platform through screws. The horizontal position of the clamping mechanism 2 is adjusted.

When the utility model is used, the actuator 23 drives the pressing block 24 to press and lock the two sides of the test sample 3; when an accident occurs in the test, the oil cylinder is only required to be decompressed, the pressing block 24 returns along the guide hole, and the test sample 3 is in a free state. At this time, the battery can be evacuated through the emergency evacuation system.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
