[0023] Example

[0024] Reference Figure 2-4 As shown, this utility model discloses a machining and positioning fixture for a housing 20, including a base plate 10. A clamping mechanism is provided on the base plate 10. The clamping mechanism includes a rotary clamping cylinder 101, a positioning table 102, a first telescopic cylinder 103, and a top rod 104, all arranged on both sides. The rotary clamping cylinder 101 is installed above the positioning table 102. Specifically, the shoulders 201 on both sides of the housing 20 are placed on the positioning table 102, and the rotary clamping cylinder 101 is controlled to press the shoulders 201 on the positioning table 102 to achieve positioning of both sides of the housing 20.

[0025] Reference Figure 2-4 As shown, the piston rod of the first telescopic cylinder 103 is hinged to a first pressure rod 1031. The middle part of the first pressure rod 1031 is hinged to the cylinder body of the first telescopic cylinder 103, and the end of the first pressure rod 1031 is positioned above the top rod 104. Specifically, the tail plate 202 at the other end of the housing 20 is placed on the top rod 104. By controlling the first telescopic cylinder 103 to extend the piston rod, the first pressure rod 1031 swings around the hinge point hinged to the cylinder body of the first cylinder, pressing the tail plate 202 of the housing 20 against the top rod 104, thereby achieving the positioning of the tail plate 202 of the housing 20. By rotating the clamping cylinder 101 to press the two shoulders 201 of the housing 20 against the positioning table 102, and by the first telescopic cylinder 103 driving the first pressure rod 1031 to press the tail plate 202 of the housing 20 against the top rod 104, the housing 20 is quickly clamped and fixed, and the flanging process of the housing 20 is improved, thus increasing the processing efficiency.

[0026] Reference Figure 2-4 As shown, a limiting module is provided on the base plate 10. The limiting module includes a positioning block 1021 set on the positioning platform 102 and a spring push rod installed on the base plate 10. The spring push rod faces the first telescopic cylinder 103. Specifically, the spring push rod pushes the housing 20 to move towards the first telescopic cylinder 103, so that the shoulders 201 on both sides of the housing 20 press against the positioning block 1021, thus limiting and pressing the housing 20 along its length. Further, a screw 106 is installed on one of the positioning platforms 102, facing the other positioning platform 102. Rotating the screw 106 extends it towards the other positioning platform 102, pressing the housing 20 onto the other positioning platform 102. The spring push rod and the screw 106 achieve positioning of the housing 20 in two mutually perpendicular directions.

[0027] Reference Figure 2-4 As shown, a fixing rod is further installed on the base plate 10, and a spring ball 108 is installed on the fixing rod. The spring ball 108 presses against the housing 20 to prevent gaps from being left between the housing 20 and the positioning block 1021, which would cause vibration during processing.

[0028] Reference Figure 2-4 As shown, the base plate 10 is provided with second telescopic cylinders 107 on both sides of the first telescopic cylinder 103. The piston rod of the second telescopic cylinder 107 is hinged to a second pressure rod 1071. The middle part of the second pressure rod 1071 is hinged to the cylinder body of the second telescopic cylinder 107. The second pressure rod 1071 is Z-shaped. By controlling the second telescopic cylinder 107 to extend the piston rod, the two second pressure rods 1071 are pushed to press the end of the housing 20 near the tail plate 202 against the top rod 104, so as to prevent the housing 20 from tilting due to a single force on one end, and to further press and fix the housing 20.

[0029] In addition, a support protrusion 109 is further installed on the base plate 10. The support protrusion 109 is height adjustable and is used to support the housing 20.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
