In the hotel food and beverage trade, the dining car is used for stacking food or tableware, and the major structure of this kind of dining car is formed by polylith baffle and concatenation, and the bottom sets up the gyro wheel, and when producing this kind of dining car, the welding is more arduous, and each baffle welds with the vertical retort one by one, not only wastes time and energy, and to the depth of parallelism of each baffle, the depth of parallelism of each vertical retort, the interval of adjacent baffle, the interval isoparametric of adjacent riser not good hold, cause the specification not uniform, the problem that the defective percentage is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that exists to current technique, provide a positioning mechanism on welding jig, the utility model aims to solve the technical problem how to treat that fixed work piece carries out accurate location, and convenient operation.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a positioning mechanism on welding jig, its characterized in that, welding jig includes the activity curb plate, positioning mechanism includes permanent magnetism piece, iron plate and mount pad, sliding connection has two guide bars on the mount pad, the inner of guide bar is provided with a clamp plate, the outer end of guide bar is fixed and is provided with a holding piece, permanent magnetism piece is fixed on holding the piece, the iron plate is fixed on the mount pad, the mount pad is fixed on the activity curb plate.

Although the position of vertical retort receives the restriction of horizontal spacing groove one and horizontal spacing groove two, however, it is only spacing and the location of perpendicular vertical retort direction, fine location has not been carried out yet along the vertical retort direction, the clamp plate can support the tip at the vertical retort, under the exogenic action, overcome the adsorption affinity between permanent magnetism piece and the iron plate, it can keep away from the mount pad to control the piece, when promoting to hold the piece and be close to the mount pad, the adsorption affinity between permanent magnetism piece and the iron plate can order about the clamp plate and only press the tip at the vertical retort, and can overcome certain external force, and the steam generator has convenient operation, the location is accurate, can not cause advantages such as vertical retort lax.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, 2, 3 and 5, the dining car comprises a plurality of partition boards 11 distributed in parallel and vertical bars 12 connecting the partition boards 11, the clamp comprises a base plate 2, a fixed side plate 3 vertically fixed on the base plate 2 and a movable side plate 4 connected on the base plate 2 in a sliding manner, the fixed side plate 3 and the movable side plate 4 are parallel to each other, and the inner side surface of the fixed side plate 3 is provided with a first vertical limiting groove 31 corresponding to each partition board 11 and a first transverse limiting groove 32 corresponding to each vertical bar 12; the side face of the movable side plate 4 close to the fixed side plate 3 is provided with a vertical limiting groove II 41 corresponding to the vertical limiting groove I31 one by one and a transverse limiting groove II 42 corresponding to the transverse limiting groove I32 one by one, and the movable side plate 4 can be fixed with the base plate 2 through a locking mechanism.

The base plate 2 is provided with a plurality of guide grooves, and the bottom of the movable side plate 4 is provided with a guide rail matched with the guide grooves.

The base plate 2 is provided with bottom limiting grooves 21 corresponding to the partition plates 11 one by one.

The locking mechanism comprises a sleeve fixed on the base plate 2, a push rod 51 is connected in the sleeve in a sliding mode, one end of the push rod 51 is fixedly connected with the movable side plate 4, a handle 52 is hinged to the base plate 2, and a swing arm 53 is hinged between the handle 52 and the other end of the push rod 51.

The locking mechanism may be a structure in which the movable side plate 4 is fixed to the base plate 2 by a bolt, or may be a compression spring connected between the base plate 2 and the movable side plate 4.

The edge of the base plate 2 is provided with a plurality of hanging rings 6.

As shown in fig. 3 and 4, each movable side plate 4 is provided with a positioning mechanism capable of positioning an end of the vertical bar 12, the positioning mechanism includes a permanent magnet 71, an iron block 72 and a mounting seat 73, the mounting seat 73 is slidably connected with two guide rods, the inner ends of the guide rods are provided with a pressing plate 74, the outer ends of the guide rods are fixedly provided with a holding block 75, the permanent magnet 71 is fixed on the holding block 75, the iron block 72 is fixed on the mounting seat 73, and the mounting seat 73 is fixed on the movable side plate 4.
