Detailed Description
In order to further understand the technical solution of the present invention, the present invention will be further explained by the following embodiments with reference to the attached drawings.
As shown in fig. 1-3, the utility model discloses fork truck portal slope jar support tailor-welding positioning tool includes support 1, connects in support 1's rectangle positioning frame 2, abnormal change piece 4 to and the location axle 3 that corresponds with corresponding work piece fork truck portal's slope jar support 8, etc. The transformation block 4 is L-shaped.
Two arms (or two free ends) of the L-shaped deformation conversion block 4 are respectively provided with equivalent conversion positioning holes 4b, the combined corner of the two arms of the L-shaped deformation conversion block 4 is provided with an equipment hole 4c, the middle part of the rectangular positioning frame 2 is provided with a rectangular positioning frame equipment hole 2c corresponding to the equipment hole of the L-shaped deformation conversion block 4, and two opposite sides of the equipment hole 2c of the rectangular positioning frame 2 are respectively provided with rectangular positioning frame equivalent conversion positioning holes 2b corresponding to the equivalent conversion positioning holes 4b of the L-shaped deformation conversion block 4.
The distance between the equipment hole of the L-shaped transformation block 4 and the corresponding equivalent transformation positioning hole is greater than or less than the corresponding distance between the equipment hole of the L-shaped transformation block and the other equivalent transformation positioning hole. The free end surfaces of the two arms of the L-shaped transition block 4 form workpiece surfaces. The equivalent conversion positioning holes have the same aperture and type.
The L-shaped transition block 4 is positioned at the inner side of the rectangular positioning frame and is assembled and connected with the rectangular positioning frame 2 through an equipment pin shaft 6 and an equipment hole of the L-shaped transition block. When the L-shaped deformation conversion block 4 is assembled and connected, one end of the equipment pin shaft 6 is provided with an expanding limiting head, the other end of the equipment pin shaft is provided with a lock pin hole, and the L-shaped deformation conversion block 4 is connected to the rectangular positioning frame and then locked by the cotter pin 10 through the lock pin hole in a mode of preventing falling out.
The transformation positioning pin 5 can be transformed and positioned between the L-shaped transformation block 4 and the rectangular positioning frame 2 through the equivalent transformation positioning hole 4b of the L-shaped transformation block 4 and the equivalent transformation positioning hole 2b of the rectangular positioning frame 2.
When the shape of the L-shaped deformation conversion block 4 needs to be adjusted and converted, the conversion positioning bolt 5 is pulled away from the L-shaped deformation conversion block 4 and the rectangular positioning frame 2, the L-shaped deformation conversion block 4 is rotated for an angle around the equipment pin shaft 6, and the state of the L-shaped deformation conversion block is converted, so that the original transverse arm and the original vertical arm of the L-shaped deformation conversion block 4 are exchanged, namely the original transverse arm is changed into the vertical arm, and the original vertical arm is changed into the transverse arm. Because the equivalent transformation positioning holes 4b of the two arms of the L-shaped transformation block 4 have different distances from the equipment holes, after the L-shaped transformation block 4 is changed from one state to the other state, the transformation positioning bolt 5 is inserted into the equivalent transformation positioning holes of the L-shaped transformation block 4 and the rectangular positioning frame 2. After the state of the L-shaped transition block 4 is changed, the relative height of the equivalent transition positioning hole 4b above the rectangular positioning frame 2 is changed accordingly. The purpose of clamping, splicing and welding and positioning the inclined cylinder supports 8 of workpieces with different heights is achieved. In this example, the L-shaped transition block 4 can rotate clockwise or counterclockwise around the pin 6 of the apparatus by a certain angle, such as 90 degrees, so that the apparatus is in two working states to adapt to the tailor-welding positioning of two workpieces of different sizes.
One of the two equivalent transformation positioning holes 4b of the L-shaped transformation block 4 is positioned above the rectangular positioning frame 2. The positioning shaft 3 can be sleeved on the transformation conversion block 4 from one end through an equivalent conversion positioning hole 4a of the L-shaped transformation conversion block, which is positioned above the rectangular positioning frame 2, and meanwhile, the workpiece inclined cylinder support 8 can be sleeved on the positioning shaft 3 through a corresponding assembling hole.
When the device is used, the metamorphosis conversion block matched with the corresponding portal is selected to be assembled on the rectangular positioning frame through the equipment pin shaft 6, and the device is locked in an anti-falling mode through the cotter pin 10; rotating the metamorphosis conversion block to a proper state around the equipment pin shaft 6 according to the height requirement of the inclined cylinder support 8, and inserting a conversion positioning bolt; the inclined cylinder support is placed on the corresponding inclined plane type support body 7, the positioning shaft is inserted into the equivalent conversion positioning hole of the metamorphosis conversion block, which is positioned above the rectangular positioning frame 2, and is simultaneously inserted into the corresponding assembly hole of the inclined cylinder support, the inclined cylinder support is abutted against the corresponding portal upright post through manual operation, and the inclined cylinder support and the corresponding part of the portal upright post are spliced and welded in sequence. The inclined plane type supporting body 7 can be arranged on a table top or the ground, and the corresponding part of the inclined plane can be adapted to the corresponding supporting height by moving the position of the inclined plane type supporting body.
In another embodiment, the transformation block is rectangular, two equivalent transformation positioning holes of the rectangular transformation block are opened at two corners of a diagonal line of the rectangular transformation block, and a mounting hole of the rectangular transformation block is opened at a corresponding corner of another diagonal line of the rectangular transformation block. The rest of the structure, the corresponding modification, the using method, etc. of this embodiment can be similar to the above embodiments.
When the type or height of the inclined cylinder support is required to be changed, the transformation and positioning bolt connected to one end of the rectangular positioning frame is pulled out, the transformation and conversion block is converted to another state by rotating, and then the transformation and positioning bolt is inserted into the equivalent transformation and positioning hole at the other end of the rectangular positioning frame and penetrates through the effective transformation and positioning hole at the corresponding position of the transformation and conversion block, so that the transformation and conversion block is converted to another state, the positioning and the tailor-welding of the inclined cylinder support of different types are realized, and the tooling operation is similar to the steps. The method has better universality, can save time and energy for replacing and installing the positioning tool, is high in positioning precision, and is good in quality of the tailor-welded door frame.
