Description

Technical Field

[0002] Casings generally refer to the outer shells used in various electronic products. Based on their intended use, they can be categorized into computer cases, TV cases, mobile phone cases, instrument cases, motor cases, and micro motor cases. Based on their materials, they can be divided into plastic cases, alloy cases, and composite materials.

[0003] In order to meet the corresponding installation and appearance requirements, corresponding shell processing is required. In this process, corresponding fixtures are required for auxiliary fixation. There is a fixture for processing automobile generator shells with patent announcement number CN208083925U, which has four fixed clamping arms on the positioning block. The fixed clamping arms have grooves and protrusions that match the workpiece, which can place the generator shell stably. The positioning strips can be set to circumferentially position the generator shell, which can better fix the generator shell during processing. The fixed clamping arms can be squeezed inward by the cylinder assembly, which can fix the workpiece more firmly, avoid shaking of the generator shell during processing, improve the accuracy of drilling holes in the generator shell, and improve the processing efficiency and quality of the generator shell.

[0004] However, the device has a constant position after the shell is clamped, which makes it difficult to meet some special processing requirements and is not practical enough. Utility Model Content

A rotation positioning mechanism is provided on the outside of the base 9. The motor housing processed by the agent is placed inside the positioning groove 3 of the motor housing for preliminary positioning. After that, multiple groups of tightening cylinders 4 are operated synchronously to drive the corresponding tightening contact pieces 5 to move inward and tighten them to the corresponding positions of the motor housing. On this basis, the telescopic rod 14 can be extended and retracted accordingly through the operation of the oil cylinder 13. Through the change of the spacing between the oil cylinder 13 and the telescopic rod 14, the restraining shaft 7 moves through the middle sleeve 6. Under the fixed connection of the connecting frame 8 to the base 9, the two sets of articulated frames 10 are constrained by the articulated shaft 11 to make the articulated block 12 move, so that the oil cylinder 13 and the telescopic rod 14 are offset accordingly.

On this basis, the operation of the oil cylinder 13 can make the telescopic rod 14 extend and retract accordingly, and the distance between the oil cylinder 13 and the telescopic rod 14 changes, and the shaft 7 is constrained to move in the middle sleeve 6. Under the fixed connection of the connecting frame 8 to the base 9, the two groups of articulated frames 10 are constrained by the articulated shaft 11 to make the articulated block 12 move, so that the oil cylinder 13 and the telescopic rod 14 are offset accordingly.
