Description

Technical Field

[0001] The present invention relates to a device and method for adjusting the level of a tapered cabin busbar for fitters, which is used for adjusting the level of a tapered cabin busbar, in particular for achieving the leveling of a tapered cabin busbar with a cone angle of 0 to 40 degrees. Background Art

[0002] In benchwork production practice, it is often necessary to level the busbars of a tapered cabin. For example, a pneumatic tapping machine is used to machine threaded holes perpendicular to the busbars on the outer surface of the tapered cabin. The common method is to make a tapered groove tooling that matches the cone angle of the cabin. This method of leveling the busbars of a tapered cabin has the following two shortcomings:

[0003] 1) A cabin body with a certain angle needs to be equipped with a matching tapered groove tooling. Once the cone angle of the cabin body changes, the tooling needs to be remade, which has poor versatility.

[0004] 2) The conical groove tooling requires the use of ball cutter CNC programming to fit the conical surface, which has a high processing cost. When faced with the task of producing a variety of small batches of conical cabins, the tooling production cost often exceeds the expected profit of the product.

[0005] Therefore, how to achieve the leveling of the conical cabin busbar at a low cost based on the characteristics of benchwork while taking into account a certain degree of versatility is a difficult problem that needs to be solved urgently. Summary of the Invention

[0006] The purpose of the present invention is to provide a device and method for adjusting the level of a conical cabin busbar for fitters, which is suitable for the production of various conical cabins and has simple operation and low production cost.

The driving screw 111 is mounted in the rotating plate 9 via the two screw brackets 10, and the right-handed right-angle slider 13 and the left-handed right-angle slider 14 are threaded on the driving screw 111 and are movable in the rotating plate 9. The thread of the driving screw 111 is half right-handed and half left-handed. When the driving screw 111 rotates, the right-handed right-angle slider 13 and the left-handed right-angle slider 14 move simultaneously toward the center or to both sides on the driving screw 111.

When the driving screw II12 rotates, the right-handed ball slider 16 and the left-handed ball slider 17 move simultaneously toward the middle or simultaneously to both sides on the driving screw II12.

[0010] A handle 18 is fixedly connected to one end of the driving screw II12 of the second slider screw mechanism 40, and the handle 18 can drive the driving screw II12 to rotate.

[0011] A bearing cover 7 is further provided between the first slider screw mechanism 30 and the rocking plate 4 . The bearing cover 7 is fixedly connected to the first slider screw mechanism 30 .

[0013] The first step is to preliminarily adjust the position of the ball head slider mounting seat 15 in the guide plate 19 according to the total length of the cabin body, buckle the large end face of the conical cabin body 1 on the side surface with the groove of the rotating plate 9, then insert a hexagonal wrench into the hexagonal socket on the end face of the driving screw 111 and apply torque to separate the right-hand right-angle slider 13 and the left-hand right-angle slider 14 until the inner diameter of the large end of the conical cabin body 1 is slightly squeezed to achieve radial positioning. Finally, gently place the small end of the conical cabin body 1 in contact with the ball heads of the right-hand ball head slider 16 and the left-hand ball head slider 17;

[0014] Step 2: Hold the spirit level with your left hand and place it in the direction of the uppermost busbar of the cabin and observe the spirit level. At the same time, turn the handle 18 with your right hand to apply torque to adjust the distance between the right-hand ball slider 16 and the left-hand ball slider 17 until the spirit level displays level. If the distance between the right-hand ball slider 16 and the left-hand ball slider 17 cannot be adjusted to the limit position and leveling is still not achieved, move the ball slider mounting seat 15 left and right along the groove of the guide plate 19 and turn the handle 18 to adjust the distance between the right-hand ball slider 16 and the left-hand ball slider 17 to achieve the leveling of the conical cabin 1.

[0015] Step 3: Tighten the fastening screws 21 covering the ball head slider mounting seat 15 on the side of the guide plate 19 to position the ball head slider mounting seat 15 to prevent it from sliding along the groove. At this point, the busbar of the conical cabin 1 is leveled. Beneficial effects of the present invention:

[0016] 1. The device of the present invention is easy to operate and has universality, and can realize the leveling of a variety of conical cabin busbars with a cone angle of 0 to 40 degrees.

[0017] 2. The rotational freedom of the conical cabin body 1 along the axis of the present invention is retained. The cabin body can be rotated along the axis while the busbar of the conical cabin body is adjusted to the level, thereby ensuring that all features on the outer circumference of the conical cabin body can be moved to the upper part for the fitter to perform the next step of tapping and other operations.

[0018] 3. The clamping stress of the present invention is small and will not affect the accuracy of the conical cabin. BRIEF DESCRIPTION OF THE DRAWINGS

4. A method for adjusting the level of a tapered busbar for a fitter's cabin, using the device for adjusting the level of a tapered busbar for a fitter's cabin as claimed in claim 2, comprising the following steps: The first step is to preliminarily adjust the position of the ball head slider mounting seat (15) in the guide plate (19) according to the total length of the cabin body, buckle the large end face of the conical cabin body (1) on the side surface with the groove of the rotating plate (9), and then insert a hexagonal wrench into the inner hexagon of the end face of the driving screw I (11) to apply torque to move the right-hand right-angle slider (13) and the left-hand right-angle slider (14) away from each other until the inner diameter of the large end of the conical cabin body (1) is slightly squeezed to achieve radial positioning, and finally gently place the small end of the conical cabin body (1) in contact with the ball heads of the right-hand ball head slider (16) and the left-hand ball head slider (17); Step 2: Hold the spirit level with your left hand and place it in the direction of the uppermost busbar of the cabin to observe the spirit level. At the same time, turn the handle (18) with your right hand to apply torque to adjust the distance between the right-hand ball slider (16) and the left-hand ball slider (17) until the spirit level shows level. If the distance between the right-hand ball slider (16) and the left-hand ball slider (17) cannot be adjusted to the limit position and leveling is still not achieved, move the ball slider mounting seat (15) left and right along the groove of the guide plate (19) and turn the handle (18) to adjust the distance between the right-hand ball slider (16) and the left-hand ball slider (17) to achieve the leveling of the conical cabin (1); Step 3: Tighten the fastening screws (21) covering the ball head slider mounting seat (15) on the side of the guide plate (19) to achieve the positioning of the ball head slider mounting seat (15) to prevent it from sliding along the groove. At this point, the busbar of the conical cabin (1) is leveled.
