[0001] This utility model relates to the field of inspection tools for aluminum alloy workpieces, specifically to a tooling for inspecting the dimensions of the lower casing of new energy batteries. Background Technology

[0002] The complex structure of the lower casing of new energy batteries makes dimensional inspection also complex. The accuracy of the lower casing dimensions greatly affects the assembly efficiency of new energy batteries. There is an urgent need for a testing fixture that can accurately detect the dimensions of the lower casing of new energy batteries. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tooling for detecting the dimensions of the lower casing of a new energy battery.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a tooling for detecting the dimensions of the lower casing of a new energy battery, comprising: a detection platform, characterized in that: a loading platform is provided in front of the detection platform, the width of the loading platform is smaller than that of the detection platform, the rear end of the loading platform is locked to the front end of the detection platform by bolts, a loading position is provided on the loading platform, and a detection position is provided on the detection platform, two guide rails arranged side by side with a front-to-back direction are laid on the loading platform and the detection platform, a trolley is slidably mounted on the two guide rails, and after the trolley is pushed, the trolley can move along the guide rails from the loading position to the detection position, and a [missing information - likely a device or tool] is fixed at each of the four corners of the trolley. Rubber corner protectors are used to limit and support the lower housing when it is placed on the trolley. A support arm is installed on each of the left and right sides of the trolley, with a vertical positioning post at the top of each arm. After the lower housing is placed on the trolley, it is positioned forward, backward, left, and right by inserting the two positioning posts into the through holes on the left and right side lugs of the lower housing. A positioning block with a positioning slot is fixed to one side wall of the trolley. A horizontal pin tube running left and right is installed on one side of the detection platform where the positioning block is located, with a pin inserted through the tube. The trolley can be manually driven after sliding to the detection position. The pins are inserted into the positioning slots in a left-right direction to position the trolley forward and backward. Columns are installed on the left, right, and rear sides of the detection position on the detection platform. The combined inspection fixture is supported directly above the detection position by fixing its various parts to the tops of the corresponding columns. The combined inspection fixture has several vertically arranged vertical detection pins that are spring-returned upwards and several horizontally arranged horizontal detection pins that are spring-returned outwards. Positioning holes are also provided on the left and right sides of the combined inspection fixture for the positioning rods of the lower housing to be inserted into for positioning the lower housing. Lifting cylinders that can extend upwards are installed on the detection platforms on the left and right sides of the detection position. After the housing is positioned on the trolley and then slid and transported to the inspection position, each lifting cylinder extends simultaneously and abuts against the corresponding lugs on the lower housing, allowing the lower housing to be lifted off the trolley and raised to a position abutting against the combined inspection fixture. At this time, the positioning rods on the left and right sides of the lower housing can be inserted into the two positioning holes of the combined inspection fixture, allowing the lower housing to be positioned. The position, size, and diameter of each vertical hole on the lower housing can be detected by whether the corresponding vertical inspection pin can be inserted downwards, and the position, size, and diameter of each horizontal hole on the lower housing can be detected by whether the corresponding horizontal inspection pin can be inserted inwards.

[0005] Furthermore, in the aforementioned new energy battery lower housing size detection fixture, the top of the positioning column is set to be spherical.

[0006] Furthermore, in the aforementioned new energy battery lower housing size inspection fixture, the piston rod top of each lifting cylinder is fitted with a rubber sleeve.

[0007] Furthermore, in the aforementioned new energy battery lower casing size inspection fixture, support wheels are provided at the four corners of the bottom of the inspection platform, and the front end of the loading platform is supported by two support legs.

[0008] Furthermore, the aforementioned new energy battery lower box size inspection fixture also includes anti-collision pads installed on the edge of the vehicle.

[0009] Furthermore, in the aforementioned new energy battery lower casing size detection fixture: an L-shaped groove is provided on the side wall of the pin port, and a screw is threaded onto the rod of the pin. The screw is located in the front and rear grooves of the L-shaped groove. At this time, the pin cannot be inserted in the left and right direction due to the limitation of the front and rear grooves. After rotating the pin so that the screw enters the left and right grooves from the front and rear grooves of the L-shaped groove, the pin can be inserted in the left and right direction.

[0010] Furthermore, the aforementioned new energy battery lower casing size inspection fixture also includes: a support plate for abutting against and inspecting the outer dimensions of the lower casing.

[0011] Furthermore, the aforementioned new energy battery lower casing size inspection fixture also includes a handheld inspection tool, which is equipped with multiple fixed inspection pins.

[0012] The advantages of this utility model are as follows: the dimensional inspection fixture can lift the lower box body so that it can abut against the lower part of the combined inspection fixture. The worker only needs to operate each vertical and horizontal inspection pin to detect the position, size and diameter of each vertical hole on the lower box body by whether it can be inserted downward by the corresponding vertical inspection pin, and the position, size and diameter of each horizontal hole on the lower box body by whether it can be inserted inward by the corresponding horizontal inspection pin. This allows the fixture to quickly and accurately detect the size of the lower box body. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3As shown, the fixture for inspecting the dimensions of the lower housing of a new energy battery includes: an inspection platform 1, a loading platform 2 in front of the inspection platform 1 (the width of the loading platform 2 is smaller than that of the inspection platform 1 to facilitate manual loading); the rear end of the loading platform 2 is bolted to the front end of the inspection platform 1; a loading position is provided on the loading platform 2, and an inspection position is provided on the inspection platform 1; two parallel guide rails 3 running front to back are laid on the loading platform 2 and the inspection platform 1; a trolley 4 is slidably mounted on the two guide rails 3; after the trolley 4 is pushed, it can move along the guide rails 3 from the loading position to the inspection position; a rubber corner protector 5 is fixed at each of the four corners of the trolley 4; and the lower housing 6 is placed on the trolley 4. At this time, the four rubber corner protectors 5 can limit and support the lower box 6. A support arm 7 is set on the left and right sides of the trolley 4, and a vertical positioning post 8 is set on the top of the two support arms 7. After the lower box 6 is placed on the trolley 4, the two positioning posts 8 can be inserted into the through holes 9 on the left and right side lugs 21 of the lower box 6 to position the lower box 6 in the front, back and left and right directions. A positioning block 10 is fixed on one side wall of the left and right sides of the trolley 4. A positioning slot 11 is set on the positioning block 10. A horizontal and left and right pin tube 12 is set on one side of the detection platform 1 where the positioning block 10 is located. A pin 13 is inserted through the pin tube 12. After the trolley 4 slides to the detection position, the pin 13 can be manually driven to move left and right. The direction is inserted into the positioning slot 11 to position the trolley 4 front and back. Columns 14 are respectively set on the left, right, and rear sides of the detection position on the detection platform 1. The combined inspection fixture 15 is supported directly above the detection position by fixing its various parts to the top of the corresponding columns 14. The combined inspection fixture 15 is provided with several vertically arranged vertical detection pins 16 that are spring-reset upwards and several horizontally arranged horizontal detection pins 17 that are spring-reset outwards. Positioning holes 18 are also provided on the left and right sides of the combined inspection fixture 15 for the positioning rods 19 on the left and right sides of the lower housing 6 to be inserted into for positioning the lower housing 6. Lifting cylinders 20 that can extend upwards are respectively set on the detection platform 1 on the left and right sides of the detection position. The lower housing 6 is positioned on the trolley 4 and then slid and transported to the inspection position. Simultaneously, each lifting cylinder 20 extends and abuts against the corresponding lug 21 on the lower housing 6, lifting it away from the trolley 4 and raising it to a position abutting against the combined inspection fixture 15. At this point, the positioning rods 19 on the left and right sides of the lower housing 6 can be inserted into the two positioning holes 18 of the combined inspection fixture 15, thus positioning the lower housing 6. The position and diameter of each vertical hole on the lower housing 6 can be detected by whether the corresponding vertical inspection pin 16 can be inserted downwards. The position and diameter of each horizontal hole on the lower housing 6 can be detected by whether the corresponding horizontal inspection pin 17 can be inserted inwards. If the inspection pin cannot be inserted, it indicates a deviation in the hole size.

[0018] In this embodiment, the top of the positioning post 8 is spherical to reduce the contact area between the top of the positioning post 8 and the lug 21, making it less likely for the trolley 4 to be lifted when the lower housing 6 is lifted. Each lifting cylinder 20 has a rubber sleeve fitted on the top of its piston rod to prevent scratching the lower housing 6. Support wheels 22 are installed at the four corners of the bottom of the inspection platform 1, and the front end of the loading platform 2 is supported by two support legs 23, facilitating tooling position adjustment. Anti-collision pads 24 are also installed along the edge of the trolley 4 to prevent damage to the lower housing 6. An L-shaped groove 25 is provided on the side wall of the pin tube 12. A screw 26 is threaded onto the shaft of the pin 13. The screw 26 is located in the front and rear grooves of the L-shaped groove 25. At this time, the pin 13 cannot be inserted in the left and right direction due to the limitation of the front and rear grooves. After rotating the pin 13 so that the screw 26 enters the left and right grooves from the front and rear grooves of the L-shaped groove 25, the pin 13 can be inserted in the left and right direction. This is designed to prevent the pin 13 from being accidentally inserted.

[0019] For better inspection, it also includes: a backing plate gauge for testing the external dimensions of the lower box 6, and a handheld gauge, with multiple fixed testing pins on the handheld gauge.
