Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
As shown in fig. 1, a tool for efficiently measuring the pop-up size of a starter gear head includes an electromagnetic component housing 10, a movable iron core 8 penetrates through the electromagnetic component housing 10, and the movable iron core 8 is slidably connected with the electromagnetic component housing 10. The left end of the movable iron core 8 is provided with a clamping piece 20, the right end of the movable iron core 8 is sleeved with a movable contact 4, a plastic bushing 5 and a steel washer 2, the movable contact 4 is located between the plastic bushing 5 and the steel washer 2, the right side of the steel washer 2 is provided with a clamping ring 1, an annular groove is formed in the movable iron core 8, one end of the annular groove is provided with a check ring 7, a compression spring 6 is arranged between the check ring 7 and the plastic bushing 5, and the compression spring 6 is located inside the annular groove. The compression spring 6 is used for pushing the plastic bushing 5 to one side of the movable contact 4 to play an insulation role. An insulating pad 3 is arranged between the steel gasket 2 and the movable contact 4. A static iron core 11 and a coil 18 are arranged between the electromagnetic component shell 10 and the movable iron core 8, and a return spring 9 is arranged between the electromagnetic component shell 10 and the movable contact 4. The movable iron core 8 is provided with a limit ring 21, and the limit ring 21 is abutted against the electromagnetic component housing 10. The cross section area of the middle part of the movable iron core 8 is larger than the cross section areas of the two sides. The middle part of the movable iron core 8 is abutted to the static iron core 11, and the right end of the movable iron core 8 penetrates through the inside of the static iron core 11. The movable iron core 8 is pushed to the right end under the action of the elastic force of the return spring 9, and the limiting ring 21 is abutted with the electromagnetic component shell 10. The return spring 9 and the hold-down spring 6 are compression springs.
As shown in fig. 2 and 3, in the conventional measuring tool, when measuring, the casing 15 of the starter is fixed on the mounting plate 19, the coil 18 is energized to generate an electromagnetic field, the movable iron core 8 is magnetized and then moves to the right, the clamping member 20 drives the upper part of the shifting fork 16 to move, the shifting fork 16 rotates clockwise around the shifting fork pin 17, the lower part of the shifting fork 16 moves to the left, and the isolator 14 is pushed to move to the left and pop out. The gear head 13 is arranged on the one-way device 19, and the gear head 13 is ejected synchronously along with the one-way device 19. When the movable iron core 8 is attached to the static iron core 11, the maximum position is reached, and the position Y reached by the gear head 13 is the gear head pop-up size. After the gear head is ejected, the size (size Y) from the end face of the gear head 13 to the mounting spigot needs to be measured quickly, otherwise the switch coil 18 is burnt due to long power-on time. The dimension X is the dimension from the end face to the fitting spigot when the gear head 13 is not ejected.
And the measurement frock after the improvement, because movable core 8 receives the elastic force effect of reset spring 9 to be pushed up right-hand member, spacing ring 21 and electromagnetic component casing 10 butt, need not just can push out gear head 13 through coil 18 to the risk that coil 18 was burnt for a long time circular telegram has been avoided. When the starter is refitted, the switch cover assembly 12 of the same type of starter electromagnetic switch is dismounted and is not used, and the clamping ring 1, the steel washer 2, the insulating pad 3, the movable contact 4, the plastic bushing 5, the compression spring 6, the retainer ring 7, the movable iron core 8 and the reset spring 9 are sequentially removed for use. And (4) reassembling, namely installing the return spring 9 between the movable contact 4 and the electromagnetic component shell 10, wherein the installation positions of other parts are unchanged, so that the simple tool capable of measuring the size of the pop-up position of the gear head is formed. By installing the return spring 9 (other springs can be used) between the movable contact 4 and the electromagnetic component housing 10, the movable iron core 8 has been moved to the position of being attached to the stationary iron core 11 due to the spring force of the spring in the right direction, and the state that the electromagnetic switch generates electromagnetic attraction when being electrified so as to attract the stationary iron core is simulated. Therefore, when the device is installed on a starter, the position where the gear head is located is the size of the popping position of the gear head, and the size can be conveniently measured. Is not limited by sites, personnel and special equipment.
