Technical Field
[0001] The utility model relates to the technical field of processing equipment, in particular to a magnetic component welding fixture. Background Art
[0002] The magnetic assembly is an accessory installed in a miniature circuit breaker, such as Figure 1 As shown, it typically includes a stationary contact a, a terminal block b, and a coil c. Coil c includes a spiral body and pins located on the left and right sides of the spiral body. Terminal block b fits under the pin on the left side of coil c and is secured to terminal block b by welding. Stationary contact a fits under the pin on the right end of coil c and is secured to the pin by welding. During welding, it may be necessary to sandwich a flux sheet between the terminal block and the coil pin, and between the stationary contact and the coil pin.
[0003] The traditional magnetic component welding fixture places the coil, terminal block and static contact on the fixture in sequence, and then welds the two pins of the coil to the terminal block and the static contact in sequence. The existing welding fixture needs to drive the coil to move during welding to create a gap between it and the terminal block or contact head to facilitate the insertion of the soldering sheet. However, the existing technology does not have a structure for positioning the coil, which makes the coil easily deflected after movement, thereby affecting the quality of the final product. Summary of the Invention
[0004] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a magnetic component welding fixture with a simple structure and high welding effect, and a positioning piece is provided to position the coil so that it always remains stable during the displacement process and does not affect subsequent welding.

The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod has a round shank to contact with said linking rod.
[0006] The above technical solution is adopted, and a driving member is provided on the front side of the positioning member. Under the action of the driving member, the positioning member rotates relative to the coil placement frame, exposing the coil placement slot or partially covering the coil placement slot. When the pressing arm moves forward, it is convenient to place the coil in the coil placement slot or remove it from the coil placement slot. When the pressing arm moves backward, it can press the coil in the coil placement slot to fix it in the coil placement slot, avoiding the coil from moving and affecting the welding effect. The positioning member reset spring can quickly reset the positioning member. The lower end of the positioning member and the coil placement frame are provided with a accommodating cavity, and both ends of the positioning member reset spring are located at corresponding accommodating cavities. The push rod is pushed forward by the driving mechanism. When the first push rod moves forward, there is a gap between the coil, the terminal block and the static contact, which is convenient for inserting the welding sheet. If the welding sheet is inserted between the coil and the terminal block, the coil and the terminal block are welded first, and then the second push rod and the first push rod are pushed forward synchronously to slide forward, so that the coil and the terminal block slide forward synchronously, and there is a gap between the coil and the static contact, which is convenient for inserting the welding sheet, and then the coil and the static contact are welded. Otherwise, the coil and the static contact are welded first, and then the coil and the terminal block are welded.
[0007] A further configuration of the present invention is that the contact portion between the pressing arm and the coil is an arc-shaped surface that matches the outer peripheral shape of the coil spiral body.

[0010] The above-mentioned further arrangement makes it easier for the push rod to push the placement rack or placement seat thereon to slide back and forth, so as to facilitate the insertion of the welding rod between the coil and the terminal board or between the coil and the static contact. The fixed connection can be achieved by installing the placement rack or placement seat on the corresponding push rod through fasteners such as screws.
[0011] The present invention is further configured as follows: the slide seat and the base are slidably engaged with each other through guide rails and guide grooves; a fixed plate is provided on the rear side of the base; and a slide seat return spring is provided between the fixed plate and the slide seat for returning the slide seat forward.
[0012] With the above-mentioned further arrangement, the slide can slide back and forth on the base, giving it a floating function. During the welding process, if the welding head contacts the component and touches the slide, the slide can automatically float and adjust its position to avoid damage to the welding head.
[0013] The present invention is further configured as follows: a limit block is provided on the slide, a baffle is provided on the base in the sliding direction of the slide, and the baffle is located in front of the limit block to limit the distance the slide can be reset forward under the action of a slide reset spring.
[0014] The above-mentioned further setting is adopted to prevent the slide from sliding forward excessively and affecting the welding effect. After the limit block touches the baffle, the slide stops sliding and cannot slide forward any further, thereby limiting the sliding distance of the slide.
[0015] The utility model is further configured as follows: the rear end of each push rod is a force-bearing end, a reset block is provided at the force-bearing end, a push rod reset spring is sleeved on the push rod, the push rod reset spring is compressed between the slide seat and the reset block, and the push rod is reset backward under the action of the push rod reset spring.
