Description

Horizontal spot welding machine pressue device

Technical field

The utility model relates to a kind of hot pressing electric welding machine, relates in particular to a kind of horizontal spot welding machine pressue device.

Background technology

The welding of series excited machine rotor commutator is meant rotor coil enamelled wire and commutator hook hot pressing spot welding and coil varnish envelope curve and commutator hook groove hot pressing spot welding.Pressurization when generally welding is that the spring that relies on cylinder to promote to fixedly install between increased pressure board and the slide plate is realized, the deflection by the adjusting nut regulating spring obtains relative constant compression force.

Because the difference of product specification, the thickness of commutator hook has difference, and required pressure is different during welding.Just need to adjust the precompressed amount of spring during the different product welding.In the production process, when the replacing product is frequent, need often to adjust the precompressed amount, more loaded down with trivial details.The difference that will cause when welding pressure of the product different batches production of same model, thus the consistency of product welding quality influenced.

Therefore, need improve, the product of its same specification is welded under constant voltage,, can increase work efficiency simultaneously to improve the quality of products to the pressure structure and the mode of existing spring.

The utility model content

In view of this, the utility model provides a kind of horizontal spot welding machine pressue device, and pressing spring is arranged on the module, and the product of different size is selected for use different modules, has both guaranteed that the product of same specification welds under constant voltage, to improve the quality of products; The module of the different precompression pressing spring of fast changeable is to adapt to the product of different size, to increase work efficiency again.

The horizontal spot welding machine pressue device that the utility model provides, comprise the increased pressure board, the guide rail that add air cylinder, pressurization air cylinder driven, be installed in slide plate on the guide rail, be arranged between pressing plate and the slide plate and the bolt parallel, be enclosed within spring and the preset nut of rotation set on bolt on the bolt with the slide plate slides direction, described slide plate is connected with the plumb joint of spot welding machine, also comprise fixture block I and fixture block II, the end that described fixture block I is fixedly installed on bolt is near the preset nut, and the other end of bolt passes fixture block II and annular protrusion is set passing the end; The U-shaped draw-in groove is set respectively on described increased pressure board and the slide plate, annular groove is set respectively on fixture block I and the fixture block II and snaps in respectively in the U-shaped draw-in groove on slide plate and the increased pressure board.

Further, the bolt of described bolt is made up of the end bolt of kingbolt and reduced, and fixture block I has through hole and is enclosed within on the end bolt, screws in nut on the end bolt and compresses fixture block I.

The beneficial effects of the utility model are: the horizontal spot welding machine pressue device of the utility model structure, employing is provided with removable at any time bolt between piston rod that adds air cylinder and slide plate, spring on the bolt is adjusted the precompressed amount of spring by the preset nut, and be made into corresponding module, and be stuck on increased pressure board and the slide plate by the fixture block at bolt two ends, at the module of the different precompression pressing spring of the product fast changeable of different size to increase work efficiency, the product that had both guaranteed same specification welds under constant voltage, to improve the quality of products.

Description of drawings

Below in conjunction with drawings and embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cross section view of bolt, spring, preset nut and fixture block assembling.

Embodiment

Fig. 1 is a structural representation of the present utility model, Fig. 2 is a bolt, spring, the cross section view of preset nut and fixture block assembling, as shown in the figure: horizontal spot welding machine pressue device comprises and adds air cylinder 1, add the increased pressure board 2 that air cylinder 1 drives, spring 3, preset nut 4, bolt 7, fixture block I 8, fixture block II 9, guide rail 5 and the slide plate 6 that is installed on the guide rail 5, slide plate 6 be arranged in parallel with increased pressure board 2 and is vertical with guide rail 5, this slide plate 6 is connected with the plumb joint of spot welding machine, the vertical U-shaped draw-in groove 10 that is provided with the glide direction of slide plate 6 on increased pressure board 2 and the slide plate 6, fixture block II 9 has through hole 11, one end of bolt 7 is provided with the annular protrusion 13 of lateral dimension greater than the lateral dimension of through hole 11, the other end of bolt 7 passes fixture block II 9, spring 3 is enclosed within on the bolt, preset nut 4 rotation sets holddown spring 3 on bolt, fixture block I8 is fixedly installed on the other end of bolt, on fixture block I8 and the fixture block II9 annular groove 12 is set respectively, fixture block I8 and fixture block II9 snap in the U-shaped draw-in groove 10 on slide plate 6 and the increased pressure board 2 by the annular groove on it 12 respectively, and bolt 7 is parallel with slide plate 6 glide directions.Spring 3, preset nut 4, bolt 7, fixture block I8 and fixture block II9 are made into module, and adjust the precompressed amount of spring in advance by preset nut 4, to the product of different size, can be corresponding with it by the pressure of adjusting the disparate modules upper spring.At the product of different size, can select the module of different size for use, only need during replacing to take off from the U-shaped draw-in groove 10 of slide plate 6 and increased pressure board 2, clamp corresponding module again, the installation or removal module is more convenient, quick.
