[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in combination with the embodiments.

[0024] See Figures 1-4, this embodiment provides a fixture for machining a sensor base, which includes a bottom plate 10. Four groups of positioning blocks 11 are arranged on the bottom plate 10 to meet the requirement of machining multiple parts simultaneously. The positioning blocks 11 have a first support end face 111, a second support end face 112, and a third support end face 113. The sizes and layouts of the three support end faces are determined according to the structure and size of the parts. A first support boss 114 is arranged on the first support end face 111, a second support boss 115 is arranged on the second support end face 112, and a third support boss 116 is arranged on the third support end face 113. A pressing component 12 is arranged on one side close to the second support end face 112 for pressing the part from above. A first support component 13 is arranged on the side opposite to the pressing component 12 for supporting and pressing the part onto the second support boss 115 from the side. A second support component 14 is arranged on one side close to the second support end face 112, and a clamping component 15 is arranged on the side opposite to the second support component 14 for supporting and pressing the part in the direction of the second support component.

[0025] Specifically, the pressing component 12 includes a pressing oil cylinder 121. A pressing plate 122 is arranged at the output end of the pressing oil cylinder 121. The pressing plate 122 is driven by the pressing oil cylinder 121 to move up and down to press the center position of the part, so that the part is pressed onto the first support boss 114.

[0026] In order to press the part towards the second support boss 115, the first support component 13 includes a self-locking oil cylinder 131. The self-locking oil cylinder 131 is arranged below the bottom plate 10. A wedge block 132 is vertically arranged at its output end. A slider seat 133 is arranged on the bottom plate. The wedge block 132 can movably penetrate the slider seat 133. A slider 134 is horizontally arranged in the slider seat 133. A through wedge-shaped hole is opened on the slider 134. The wedge block 132 penetrates the wedge-shaped hole, so that when the self-locking oil cylinder 131 works, the slider 134 is driven by the wedge block 132 to move horizontally, thereby pressing and releasing the part.

[0027] In addition, a support block 135 is further arranged at the end of the slider 134 extending out of the slider seat. The support block 135 is rotatably connected to the slider 134, so that the support block can rotate horizontally to realize the floating pressing of the part.

[0028] Similarly, the structure of the second support component 14 is the same as that of the first support component 13. The difference is that no support block is arranged at the end of the slider, and a support column 141 is arranged on the bottom plate 10 below the end position.

[0029] In order to press the part towards the second support component 14, the clamping component 15 includes a clamping oil cylinder 151. A clamping head 152 is horizontally arranged at the output end of the clamping oil cylinder 151.

[0030] In order to detect whether the part is properly placed on the positioning block 11, airtight detection holes 117 are provided on the surfaces of the first support boss 114, the second support boss 115 and the third support boss 116, and an air passage communicating with the airtight detection holes 117 is provided inside the positioning block and the bottom plate 10.

[0031] To facilitate the machining of the part 16, an avoidance hole 118 penetrating inward is provided along the first support end face 111. Each oil cylinder on the bottom plate is fixed to the bottom plate by screws. The pressing force of the oil cylinder is adjustable, and the pressing action can be monitored.

[0032] Working principle: Place the part 16 on the positioning block 11, and then perform airtight detection. After the part is properly placed, the pressing oil cylinder 12, the self-locking oil cylinders in the first support assembly and the second support assembly are started simultaneously, pressing the part from above and two sides respectively. Finally, the clamping oil cylinder 15 is started to drive the clamping head 152 to clamp the part, and the entire clamping process ends.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
