The utility model discloses a kind of lithium battery pole piece thickness measuring device, including installation base, adjusting assembly, thickness measuring sensor and calibration module, the adjusting assembly is set on the installation base, the thickness measuring sensor is used to measure the thickness of pole piece, the calibration module is used to calibrate the measurement data of the thickness measuring sensor, the adjusting assembly is used to adjust the position of the thickness measuring sensor;The adjusting assembly includes adjusting plate and fixed plate, the adjusting plate is slidably connected on the installation base, the side of the adjusting plate is connected with the fixed plate, locking structure is provided on the fixed plate, the locking structure is used between the fixed plate and the installation base Fixed / unlocked, support plate is provided on the adjusting plate, the thickness measuring sensor is installed on the support plate.The utility model discloses a kind of lithium battery pole piece thickness measuring device with the advantages of improving measurement accuracy, realizing quick positioning locking, simplifying calibration process, enhancing structural stability.

The utility model discloses a quick positioning and locking mechanism of a coke tank carrier loader, which comprises a carrier loader main body and a coke tank main body, the top of the carrier loader main body is fixedly connected with a fixed seat, a supporting seat is arranged above the fixed seat, a buffer component is arranged between the supporting seat and the fixed seat, a positioning component is arranged at the top of the supporting seat, and the positioning component is fixedly connected with the fixed seat. The buffering part comprises sliding grooves formed in the periphery of the top of the fixed seat, sliding blocks connected with the sliding grooves, first springs fixedly connected with one sides of the sliding blocks, and inclined rods connected with the tops of the sliding blocks. The problems that when an existing coke tank carrier loader is used, although the coke tank can be positioned and fixed, the carrier loader is easily damaged and the service life of the carrier loader is affected due to the fact that the coke tank is relatively heavy and is in rigid contact with the carrier loader are solved.

The present invention relates to a roller coating machine group, which realizes the locking and unlocking of the roller coating vehicle through a positioner; the positioner includes a double-sided inclined wedge block, a guide slide, a positioning seat slidably arranged on the guide slide, and a positioning member arranged at the front end of the positioning base; the positioning seat is provided with a bearing drive groove, and the bearing drive groove has two bearing drive surfaces arranged in sequence along the sliding direction of the positioning base, and the two bearing drive surfaces are both inclined surfaces with an angle with the sliding direction of the positioning base, and the positioning member is inserted into the positioning notch of the roller coating vehicle or detached from the positioning notch of the roller coating vehicle through the cooperation of the two wedge surfaces of the double-sided inclined wedge block and the two bearing drive surfaces. The present invention completes the positioning and unlocking of the roller coating vehicle by the positioning member through the cooperation of the double-sided inclined wedge block and the positioning seat with the bearing drive groove, replaces the cumbersome manual disassembly and assembly of the positioning member, and can effectively improve the efficiency of equipment maintenance; the positioner is easy to arrange, occupies a small space, can better adapt to the working condition of the narrow space between adjacent roller coating machines of the roller coating machine group, and reduces the labor cost and maintenance risk.

This utility model provides a quick-change stamping head for a sheet metal stamping forming device, including: a stamping electric cylinder, a head-changing component, and a support base. A head-changing component for quick head replacement is provided on the inner side of the lower end of the two sets of support frames. The head-changing component includes a motor and a stamping head. The head-changing component is embedded inside the two sets of support frames. A protective shell for protecting several sets of stamping heads is provided on the outer side of the motor. Compared with the prior art, this utility model has the following advantages: When the stamping head needs to be replaced, the system pauses the operation of the stamping electric cylinder, the motor automatically drives the rotary table to rotate 180 degrees, and switches the preset spare stamping head to the working position. The clamping seat achieves quick positioning and locking through the mechanical limit of the inner groove. After replacement, the side pressure limiting seat and the guide seat work together to ensure the stability of the stamping force transmission, and the cylinder head releases uniform pressure with the cooperation of the lower connecting column, thereby quickly completing the stamping head replacement.
