[0004] Introducing automated processing equipment specifically for the yoke coil assembly is a common solution, but it is very difficult to effectively achieve the automated processing of this complex product. And to introduce automated processing equipment, it is very important to design a fixture that can undertake each process. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the shortcomings and deficiencies existing in the prior art, and to provide a fixture for a yoke coil assembly.

[0006] The technical solution adopted by the utility model is as follows: The present application provides a fixture for a yoke coil assembly, which is installed on the edge of a turntable and includes a first base, a first slide plate, and a first main body. The first main body is arranged on the first slide plate, and a static contact rod assembly positioning structure and a coil assembly positioning structure are arranged thereon. The first main body is vertically arranged in the radial direction relative to the turntable, the first slide plate is inclined relative to the first main body, the first base and the first slide plate are arranged in the same direction, and the first slide plate is slidably arranged on the first base.

[0007] In some embodiments, a first rear baffle is arranged at the rear side of the first base, a first front baffle is arranged at the front side thereof, a first spring is arranged between the first rear baffle and the first slide plate, and under the action of the first spring, the first slide plate abuts against the first front baffle.

Under the action of the second spring, the first coil clamping block is in a clamping state;

[0009] The positioning structure of the static contact rod assembly includes a first positioning groove provided on the static contact rod positioning plate and a first clamping groove formed by the static contact rod clamp block and the static contact rod positioning plate;

[0010] The positioning structure of the coil assembly includes a second positioning groove provided on the yoke positioning block and a second clamping groove formed by the first coil clamp block, the first yoke clamp block and the yoke positioning block.

[0011] In some embodiments, a first push rod, a second push rod and a third push rod are slidably arranged on the first main body along a direction perpendicular to the first slideway.

[0030] Embodiment 1:

[0031] As Figures 1 to 4 shown, this embodiment provides a yoke coil assembly fixture installed on a turntable. During the rotation of the turntable, it successively passes through each workstation at the edge of the turntable to realize the automatic assembly of the yoke coil assembly.

[0032] As Figure 5 shown, the yoke coil assembly a includes a yoke a1, a static contact rod assembly a2 and a coil assembly a3. The static contact rod assembly a2 includes a static contact rod a21 and a contact a22; the coil assembly a3 includes an iron core assembly a31 and a coil a32. The iron core assembly a31 includes a coil skeleton, a moving iron core, a static iron core, a push rod and an iron core spring;

[0033] Among them, the contact a22 is welded to the static contact rod a21 to form the static contact rod assembly a2. The iron core assembly a31 and the coil a32 are inserted into each other to form the coil assembly a3. The static contact rod a21 in the static contact rod assembly a2, the coil a32 in the coil assembly a3 and the yoke a1 are welded to form the yoke coil assembly a. Here, the welding is performed with the three stacked together, and this welding position is called the welding part A;

[0034] The fixture c includes a first base c1, a first slide plate c2 and a first main body c3. The first main body c3 is arranged on the first slide plate c2, and a static contact rod assembly positioning structure c4 and a coil assembly positioning structure c5 are arranged thereon;

[0035] The first main body c3 is arranged perpendicular to the radial direction of the turntable in the first turntable device 1, and the first slide plate c2 is arranged obliquely relative to the first main body c3, that is, the first slide plate c2 is not perpendicular to this radial direction, so that the sliding direction of the first slide plate is perpendicular to the welding end face of the welding part A. The first base c1 and the first slide plate c2 are arranged in the same direction, and the first slide plate c2 is slidably arranged on the first base c1. Such a setting is based on the structural characteristics of this electromagnetic system. Among them, the positions where the static contact rod in the static contact rod assembly, the coil in the coil assembly and the yoke need to be welded are inclined relative to the assembly position of the coil assembly and the yoke. While ensuring the convenience of feeding each part and the welding quality at this position, the traditional fixture with the same-direction sliding setting cannot meet this requirement. The same-direction sliding setting means that both the slide plate and the base are perpendicular to the radial direction of the turntable in the first turntable device 1, and then the slide plate slides relative to the base in this radial direction.

[0036] Secondly, a first rear baffle c6 is arranged at the rear side of the first base c1, and a first front baffle c7 is arranged at the front side thereof. A first spring is arranged between the first rear baffle c6 and the first slide plate c2. Under the action of the first spring, the first slide plate c2 abuts against the first front baffle c7.

[0037] Secondly, a first positioning seat c8 is arranged at the front side of the first main body c3. A yoke positioning block c9 is slidably arranged at the front side of the first positioning seat c8. A first slideway c30 is arranged at the front side of the first main body c3. A first yoke clamping block c10 and a static contact rod clamping block c11 are slidably arranged in the first slideway c30. A static contact rod positioning plate c12 is arranged on the first positioning seat c8. The front end of the yoke positioning block c9 is hinged with a first coil clamping block c13. A second spring is arranged between the first coil clamping block c13 and the yoke positioning block c9. Under the action of the second spring, the first coil clamping block c13 is in a clamping state;

[0038] The positioning structure c4 of the static contact rod assembly includes a first positioning groove c14 arranged on the static contact rod positioning plate c12 and a first clamping groove c15 formed by the static contact rod clamping block c11 and the static contact rod positioning plate c12;

[0039] The positioning structure c5 of the coil assembly includes a second positioning groove c16 arranged on the yoke positioning block c9 and a second clamping groove c17 formed by the first coil clamping block c13, the first yoke clamping block c10 and the yoke positioning block c9;

[0040] A first push rod c18, a second push rod c19 and a third push rod c20 are slidably arranged on the first main body c3 in a direction perpendicular to the first slideway c30. Collision blocks c21 are arranged at the rear ends of the push rods. A third spring is sleeved on each push rod, and two ends of the third spring respectively abut against the rear end face of the first main body c3 and the corresponding collision block c21.

[0041] Oblique slider parts are arranged at the front ends of the first push rod c18 and the third push rod c20. Oblique convex blocks c22 are arranged on the oblique slider parts. Oblique sliding grooves c23 matched with the oblique convex blocks c22 are arranged on the first yoke clamping block c10 and the static contact rod clamping block c11. When the first push rod c18 is pushed to move forward, through the cooperation of the oblique convex block c22 and the oblique sliding groove c23, the static contact rod clamping block c11 moves away from the static contact rod positioning plate c12, so that the first clamping groove c15 is opened, facilitating the placement of the static contact rod assembly. The same principle applies when the third push rod c20 is used.

[0042] The front end of the second push rod c19 passes through the first main body c3 and the first positioning seat c8 and is connected with the yoke positioning block c9. When the second push rod c19 is pushed to move forward, the yoke positioning block c9 moves forward synchronously. In this way, when the yoke is inserted into the second positioning groove c16 in the vertical direction, the yoke will not interfere with the static contact rod assembly.

[0043] The second positioning groove c16 includes two yoke positioning columns c24 arranged on the yoke positioning block c9. The side of the yoke positioning column c24 facing the first coil clamping block c13 is an arc-shaped clamping surface adapted to the coil.

[0044] A ceramic partition c25 is arranged on the first positioning seat c8 corresponding to the position of the welding part A. Preferably, the bottom plate of the first clamping groove c15 is a detachable ceramic partition c25, preventing damage to the fixture during welding at this part.

[0045] As Figure 6 shown, when this fixture passes through the welding station, the welding station includes a first welding electrode 160, a second welding electrode 161 and a first pre-pressing plate 162. The first welding electrode 160 is vertically slidably arranged and spaced at the rear side of the welding part A. The second welding electrode 161 is horizontally slidably arranged towards the welding part A. The first pre-pressing plate 162 is slidably arranged in the same direction as the second welding electrode 161, and before the second welding electrode 161 contacts the welding part A, it first pushes the first slide plate c2 to move backward, so that the welding part A contacts the first welding electrode 160, thus avoiding damage to the welding part A caused by the vertical movement of the first welding electrode 160.

[0046] Among them, the drive mechanism in the welding station will not be described in detail. It only needs to be able to translate the first welding electrode 160, the second welding electrode 161, and the first pre-pressing plate 162 in the required directions. For example, a structure of a cylinder cooperating with a slide rail and a slider, a structure of a motor cooperating with a lead screw and a slider, etc. can be adopted.
