Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic support manufacturing, and particularly relates to a tooling for a top frame structural member of a hydraulic support. Background Art

[0002] As Figure 2 、 3 shown, at the connection between the lifting jack 20 and the base 19 of the hydraulic support, a top frame structural member 1 as shown in Figure 1 、 2 is required. The top frame structural member 1 includes a bottom plate 2. A socket hole is provided on the inner side surface of the bottom plate 2. A left side ear plate 3, a right side ear plate 4, a front side ear plate 5, and a rear side ear plate 6 are respectively and fixedly arranged around the inner side surface of the bottom plate 2. Each ear plate is perpendicular to the bottom plate 2, and a pin shaft hole 7 is provided on each ear plate. The front side ear plate 5 and the rear side ear plate 6 of the top frame structural member 1 are connected to the base 19 through the cooperation of the base fixing pin shaft 21 and the pin shaft hole 7. The left side ear plate 3 and the right side ear plate 4 of the top frame structural member 1 are connected to the lifting jack 20 through the cooperation of the lifting jack fixing pin shaft 22 and the pin shaft hole 7. Therefore, in order to ensure the accuracy of the top frame structural member 1 during installation, the accurate positioning of the pin shaft holes 7 on each ear plate and the parallelism between two opposite ear plates have become important factors. When the existing top frame structural member 1 is installed, due to the poor positioning accuracy during the previous processing, the axis of the socket hole on the inner side of the bottom plate 2 of the top frame structural member 1 cannot be accurately vertically aligned with the pin shaft holes 7 on the ear plates, resulting in a decrease in assembly quality, an increase in the repair rate, and low production efficiency.

The technical solutions of the present utility model will be described in detail below in combination with embodiments and drawings, but the protection scope is not limited by this.

[0029] As Figure 5 As shown in FIGS. 10-11, the present utility model provides a tooling for a top frame structural member of a hydraulic support, including a column head 8, a column 9, a balance rod 10, a detection rod 12, a parallel plane detection plate 15, a connecting rod 16, a first locking bolt 11, and a second locking bolt 13.

[0030] The column head 8 is a frustum-shaped structure with a thicker upper part and a thinner lower part. An internal thread hole is provided at the center of the upper end face of the column head 8, and a plurality of through holes 18 that penetrate up and down are also provided on the column head 8. The plurality of through holes 18 are arranged in a circular array around the axis of the column head 8.

[0031] The column 9 is a vertically arranged circular rod-shaped structure. A threaded rod is fixedly provided at the lower end of the column 9. The threaded rod at the lower end of the column 9 is screwed into the internal thread hole on the upper end face of the column head 8, so as to fix the column 9 to the upper end of the column head 8. A horizontal chute is provided at the upper end of the column 9. The horizontal chute is a square through groove that penetrates at both ends. The first locking bolt 11 is screwed on the side wall of the horizontal chute.

[0032] The balance rod 10 is a horizontally arranged square rod-shaped structure. One end of the balance rod 10 is slidably inserted into the horizontal chute at the upper end of the column 9. The balance rod 10 extends along the radial direction of the column 9. The outer side surfaces of the four sides of the balance rod 10 are in sliding contact with the inner walls of the four sides of the horizontal chute. The end of the first locking bolt 11 is tightly pressed against the outer side surface of the balance rod 10, so as to fixedly connect the balance rod 10 and the column 9. A vertical chute is provided at the other end of the balance rod 10. The vertical chute is a square through groove that penetrates at both ends. The second locking bolt 13 is screwed on the side wall of the vertical chute.

[0033] The detection rod 12 is a vertically arranged square rod-shaped structure. The upper end of the detection rod 12 is slidably inserted into the vertical chute inside the balance rod 10. The outer side surfaces around the detection rod 12 are in sliding contact with the inner walls around the vertical chute. The end of the second locking bolt 13 is tightly pressed against the outer side surface of the detection rod 12, thereby fixedly connecting the detection rod 12 and the balance rod 10.

[0034] A square detection plate 14 is fixedly arranged at the lower end of the detection rod 12. The detection plate 14 is perpendicular to the balance rod 10. A square parallel plane detection plate 15 is arranged on one side of the detection plate 14 close to the column 9. The parallel plane detection plate 15 is parallel to the detection plate 14, and the width of the parallel plane detection plate 15 is the same as the width of the detection plate 14. Two upper and lower connecting rods 16 with equal lengths and parallel to each other are respectively arranged at both ends of the detection plate 14. One ends of the two connecting rods 16 are hinged to the upper and lower ends on one side of the detection plate 14, and the other ends of the two connecting rods 16 are respectively hinged to the upper and lower ends on one side of the parallel plane detection plate 15. The parallel plane detection plate 15 on one side, the detection plate 14 on one side, and the two connecting rods 16 form a parallelogram structure, so that the distance between the parallel plane detection plate 15 and the detection plate 14 can be adjusted, and at the same time, the parallel plane detection plate 15 and the detection plate 14 are kept parallel during the adjustment process.

[0035] A semi-circular positioning groove 17 is arranged in the middle of the lower end surface of the detection rod 12. The axial direction of the positioning groove 17 is parallel to the length direction of the balance rod 10.

[0036] The working principle of the present utility model is as follows.

[0037] The first step: Initial positioning of the tooling

[0038] The tooling is initially assembled. The column head 8 of the initially assembled tooling is placed inside the top frame structural member model, so that the lower end of the column head 8 is screwed into the socket hole inside the inner side surface of the bottom plate 2 of the top frame structural member model, thereby completing the mutual positioning between the column head 8 and the top frame structural member model. Then, the first locking bolt 11 and the second locking bolt 13 are loosened, so that the balance rod 10 can slide inside the horizontal chute of the column 9, and the detection rod 12 can slide inside the vertical chute of the balance rod 10. By adjusting the balance rod 10 and the detection rod 12, the position and height of the detection plate 14 are adjusted, so that the detection plate 14 extends out of the left ear plate 3 or the right ear plate 4 of the top frame structural member model, and the positioning groove 17 at the lower end of the detection plate 14 is aligned with the pin shaft hole 7 on the left ear plate 3 or the ear plate. At the same time, the distance between the parallel plane detection plate 15 and the detection plate 14 is adjusted, so that the outer side surface of the parallel plane detection plate 15 is closely attached to the outer side surface of the left ear plate 3 or the right ear plate 4, ensuring that the detection plate 14 is parallel to the left ear plate 3 or the right ear plate 4. In this way, the initial positioning of the tooling is completed.

[0039] Step 2: Fixing of the tooling

[0040] Tighten the first locking bolt 11 and the second locking bolt 13, so that the preliminarily positioned tooling is completely fixed and will not displace during subsequent operations.

[0041] Step 3: Final inspection and confirmation

[0042] After all positioning and fixing are completed, conduct a final inspection. Confirm that each part of the tooling has been accurately positioned and meets the assembly requirements.

[0043] Step 4: Fitting of the stud 8 and the top frame structural member 1

[0044] Precisely place the stud 8 of the positioned tooling inside the left side ear plate 3 or the right side ear plate 4 of the top frame structural member, so that the lower end face of the stud 8 contacts the inner side face of the bottom plate 2 of the top frame structural member 1. Pass a depth gauge through the through hole 18 on the stud 8 to touch the inner side face of the bottom plate 2 of the top frame structural member 1 for depth detection, so as to ensure that the lower end face of the stud 8 is completely fitted with the inner side face of the bottom plate 2 of the top frame structural member 1.

[0045] Step 5: Parallel plane detection and adjustment

[0046] Move the parallel plane detection plate 15 so that the parallel plane detection plate 15 contacts the outer side face of the left side ear plate 3 or the right side ear plate 4 of the top frame structural member 1 to detect whether the detection plate 14 is parallel to the left side ear plate 3 or the right side ear plate 4 of the top frame structural member 1, and ensure that the detection plate 14 of the tooling is completely parallel to the left side ear plate 3 or the right side ear plate 4 of the top frame structural member 1. If necessary, finely adjust the position and angle of the tooling until the required parallelism is achieved to ensure the accuracy of subsequent scribing and assembly.

[0047] Step 6: Punching and positioning of the pin hole 7

[0048] At this time, all positioning of the tooling is completed. At this time, the positioning groove 17 at the lower end of the detection plate 14 of the tooling corresponds to the position of the pin hole 7 on the left side ear plate 3 or the right side ear plate 4 of the top frame structural member 1. Place a center punch in the positioning groove 17 at the lower end of the detection plate 14 of the tooling, and use its tip to align with the expected center position of the pin hole 7 and strike the center punch to leave a clear marking point on the left side ear plate 3 or the right side ear plate 4. This marking point is the center position of the pin hole 7.
