Embodiment 1

[0018] Embodiment 1: refer to Figure 1~4 . A tool for press-fitting the inner core bushing of a sensor, including a bushing jacket 2 connected to the lower end of the punch 1, an inner core die head 3, a return spring 4, a forming outer die 5, fixing bolts 6, and an upper end of the inner core die head 3 A positioning head 34 for holding the sensor inner core 9 is provided, and a positioning boss is provided on the upper end of the positioning head. Forming outer mold 5 is provided with the installation hole 52 that runs through up and down, and described inner core mold head 3 is placed in installation hole 52, and between its lower end and workbench 7, reset spring 4 is arranged, and the rod end of fixing bolt 6 passes through. The inner core die head 3 and the return spring 4 are screwed to the workbench 7, the punch 1 is located above the inner core die head 3, and the lower end of the punch head 1 is connected with a bushing jacket 2.

Embodiment 2

[0021] Embodiment 2: refer to Figure 1~4 . The working principle of a pressure-fitting tool for a sensor core bushing: put the bushing 10 into the bushing jacket 2, set the sensor core 9 on the positioning head 34 of the core die head 3, and press the cylinder or oil cylinder The driven punch 1 drives the bushing jacket 2 to move downward, so that the bushing 10 is placed outside the inner core 9 of the sensor, and the bushing jacket 2 continues to move downward, indirectly pushing the inner core die head 3 downward, so that the bushing The sleeve 10 interacts with the arc surface of the second step 51, and the mouth of the bush 10 is twisted toward the center of the bush 10 so as to enclose the lower port of the sensor inner core 9. It is further attached to the end of the inner core 9 of the sensor. At this time, the return spring 4 is in a compressed state. After the punch 1 is lifted upward, the inner core die head 3 bounces up by the action of the return spring 4, and w...

Abstract

The invention relates to a pressure fitting tool for a sensor inner core bushing, which comprises a cylinder or an oil cylinder or a punch, a sleeve jacket connected to the lower end of the punch, an inner core die, a return spring, an outer mold for forming, a fixing bolt, and an inner core. The upper end of the mandrel head is provided with a positioning head for holding the inner core of the sensor, and the forming outer mold is provided with a mounting hole that penetrates up and down. The spring and the rod end of the fixing bolt pass through the inner core die head and the return spring and are screwed to the workbench. The punch is located above the inner core die head, and the lower end of the punch head is connected with a bushing jacket.

Description

technical field [0001] The invention relates to a manufacturing tool for an automobile sensor, in particular to a pressure fitting tool for a sensor inner core bush. Background technique [0002] The wheel speed sensor in the prior art is a passive wheel speed sensor, which includes a housing and a sensor core, the sensor core is located in the housing, and the bottom of the sensor core is connected to the bottom of the housing, and the sensor core includes a coil , pins and skeleton, the axial side of the skeleton is provided with a coil radially outside, two pins are packaged on the side wall of the other axial side of the skeleton, and the two ends of the pins are connected respectively from the radial side wall of the skeleton and The axial side wall protrudes out, and the two ends of the coil are respectively connected with the radial side wall pins of the frame. The coil of the frame is provided with a bushing, and the axial ends of the bush are respectively snapped in...
