The lead screw is formed by the threaded rod and the sliding block body, when the threaded rod is rotated, the rotary motion of the threaded rod is converted into the linear motion of the sliding block body, the scale pointer fixed on the sliding block body can move along with the sliding block body, and the scale position on the horizontal scale pointed by the scale pointer is the coordinate value in the current horizontal direction.
The vertical marker post comprises a vertical scale 9, a sleeve 7 and a cylinder 11, wherein the vertical scale 9 and the sleeve 7 are sequentially arranged from inside to outside; a vertical through groove is formed in the side wall of the sleeve 7; a threaded through hole 8 is formed in the vertical scale 9, a first screw penetrates through the threaded through hole 8 and is in threaded connection with the vertical scale 9. One end of the first screw extends into the through groove on the sleeve 7. The vertical scale 9 is placed in the sleeve 7 and can slide relative to the sleeve. The first screw has two functions: firstly, the position of the vertical scale 9 can be limited, firstly, the vertical scale 9 is prevented from randomly rotating in the sleeve 7, and the scale of the vertical scale 9 is constantly positioned at the position of the groove opened in the sleeve, so that the reading is convenient; secondly, because the end of the screw I extends into the through groove, the vertical scale 9 can only move within a certain range in the vertical direction. Secondly, after the vertical scale 9 moves to a proper position, the first screw is screwed down, the first screw abuts against the inner side wall of the sleeve 7, the vertical scale 9 and the sleeve 7 are connected together through the first screw in a locking mode, and relative movement between the vertical scale 9 and the sleeve 7 is avoided.
Further, the sliding plate 1 is of a U shape with a downward opening, and comprises a top plate, a first side plate and a second side plate, wherein the first side plate and the second side plate are symmetrically arranged below two ends of the top plate; a limiting hole is formed in the side plate I, and a second screw penetrates through the limiting hole. The sliding plate 1 is placed on the welding machine guide rail 13 and is in sliding fit with the welding machine guide rail 13. And after the sliding plate slides to a proper position, screwing the second screw to enable the inner end part of the second screw to be propped against the side wall of the welding machine guide rail, so that the sliding plate is locked with the welding machine guide rail 13.
Furthermore, the horizontal scale 5 and the vertical scale 9 are provided with scales, and the scales are used for displaying the Y direction and the Z direction of the cylinder.
Furthermore, the end part of the threaded rod is provided with a rotating handle 4. And the rotating handle 4 is used for driving the threaded rod to rotate.
Further, a mounting plate 10 is arranged at the top of the vertical scale 9, the bottom of the air cylinder 11 is fixedly connected to the top of the mounting plate 10, and a cylinder rod 12 of the air cylinder 11 faces upwards. The mounting plate 10 is used for mounting the air cylinder 11.
According to the product structure and the operation action of workers, the rapid positioning is realized through analysis and discovery, and the difficulty lies in how to rapidly position the oil return pipe to an accurate position. For solving these problems, the utility model designs an oil cylinder body welding angle location frock.
Specifically, a horizontal scale bar (hereinafter referred to as Y-axis) with a scale and a vertical scale bar (hereinafter referred to as Z-axis) with a connecting automatic cylinder 11 are combined to form two-axis coordinates. After the accurate measurement of the material measuring tool, the coordinate data of the two vertical axes are recorded. When the positioning device needs to be machined, the horizontal scale and the vertical scale are marked on the required coordinates, and then the rapid positioning can be completed.
The X axis is established on can slide on welding machine guide rail 13 and can realize horizontal location by the dead mechanism of selective lock, and the Y axis is established on guide rail and slider body and can be through being equipped with scale and scale, can adjust predetermined numerical value, convenient quick school to the angle. The Z axis is connected with the cylinder 11, and the vertical scale 9 and the scale are arranged on the vertical mark post, so that the preset numerical value can be adjusted, and the angle can be corrected conveniently and rapidly.
When the Y axis and the Z axis are simultaneously calibrated to a preset value (the preset value is measured by a standard physical quantity in advance), the horizontal scale 5 and the vertical scale 9 are locked. At this time, when the oil return pipe 16 is attached to the cylinder rod 12 clockwise, the C-direction hole axis of the cylinder bottom is aligned with the red line emitted by the laser marking instrument, which is the required welding angle. The cylinder 11 is connected with a welding gun advance and retreat cylinder in the welding machine 15, so that the advance and retreat cylinder is linked with the welding gun advance and retreat cylinder, and the cylinder 11 is automatically retracted after the advance and retreat cylinder is tightly propped.
As shown in fig. 2, the working process of the present invention is:
(1) the cylinder 14 with the welded oil return pipe 16 is placed on a welding machine 15.
(2) The cylinder 14 is rotated clockwise until it is fixed. The return pipe 16 must be close to the cylinder rod 12 without clearance.
(3) The red line of the cylinder bottom is shot by aligning the center of the hole of the cylinder bottom with the laser line marking instrument, and the red line shot by the laser line marking instrument must be shot on the center line of the cylinder barrel 14.
(4) The tip of the advance and retreat cylinder is pressed tightly, and the welding machine 15 is automatically started to carry out welding. The cylinder 11 retreats downward after the advancing and retreating cylinder is pushed up to prevent the oil return pipe 16 from interfering with the cylinder rod 12 when the cylinder 14 rotates.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
