Description

Technical Field

[0002] The vacuum cover is an important component of the mixing equipment. The vacuum cover feeding port is composed of a pipe body and a flange. One side of the pipe body is butted and welded to the opening of the vacuum cover cylinder body, and an end cover is connected to one side end face of the flange. During the feeding process, raw materials are added through the holes on the end face of the feeding port flange and put into the container through the pipe body. After the feeding is completed, the holes on the flange end face are sealed by the end cover. In terms of the spatial structure of the equipment, to ensure good fluidity of the material in the pipe body, the pipe body is arranged at a certain inclination angle relative to the vacuum cover cylinder body.

[0003] The welding requirements for the vacuum cover feeding port are as follows: The vacuum cover cylinder body is formed by straight seam welding of plates. The opening of the cylinder body is cut into an appropriate pre-hole during the plate blanking, and the pre-hole is formed into a butt hole adapted to the pipe body through curling and shaping. When welding the feeding port, it should be ensured that the pipe orifice of the pipe body is aligned with the opening of the vacuum cover cylinder body, and the axis of the pipe body and the center line of the opening of the vacuum cover need to form a certain preset angle as required to ensure the accuracy of the welding position of the feeding port and obtain good welding quality.

Measure the relative position of the pipe body and the vacuum cover cylinder body, and then use tools to finely adjust the outer shape of the pipe body, or grind off the spot welds and adjust the position of the feeding port again until the position meets the requirements and then complete the welding. The above process requires repeatedly connecting and separating the feeding port and the vacuum cover, which is time-consuming and laborious, the operation process is cumbersome, the labor intensity is high, and the operation efficiency is low. Problems of Technical Solution 2: The position of the feeding port needs to be repeatedly adjusted manually, and the spatial position of the feeding port on the vacuum cover cylinder body is not easy to measure, the operation difficulty is high, the skill requirements for the operator are high, and the welding positioning accuracy is difficult to guarantee, which affects the welding quality.

[0043] (1) Figures 4-6 The specific structure of the lateral adjustment component 1 is schematically shown. As Figure 4 , Figure 5 shown, the lateral adjustment component 1 of this tooling includes a positioning seat 11. The positioning seat 11 includes a base plate 13. A number of positioning blind holes 21 are provided on the base plate 13 for installing guide posts 12. A connecting through hole 14 is provided at the bottom of the positioning blind hole 21 for installing a countersunk head screw 20. A number of positioning screw holes 15 are provided on the base plate 13 for fixedly installing the center alignment component 2. A number of barrel clamping plates 18 are provided at the bottom of the front end of the base plate 13, symmetrically arranged along the center line of the base plate 13, and provided with set screw holes 19. A number of arc seat clamping plates 16 are provided at the rear end of the base plate 13, symmetrically distributed along the center line of the base plate 13, and provided with positioning screw holes 17. As Figure 6 shown, the positioning blind holes 21 on the base plate 13 are in fit with the outer circle of the guide post 12. The bottom of the guide post 12 is provided with a fixing screw hole 22, and the guide post 12 is fixed at the corresponding position on the base plate 13 by a countersunk head screw 20. As Figure 7 shown, when the tooling is in use, the lower end face of the middle part of the base plate 13 is fitted and installed with the upper end face of the vacuum hood flange 10, that is, the vacuum hood flange 10 is located in the gap between the barrel clamping plates 18 and the arc seat clamping plates 16. The gap formed between the vacuum hood flange 10 and the arc seat clamping plates 16 is used for installing the center alignment component 2. The outer clamping bolt 24 is connected to the positioning screw hole 17 of the arc seat clamping plate 16, and the end of the outer clamping bolt 24 limits the center alignment component 2 on the outer side surface of the vacuum hood flange 10. An inner clamping bolt 23 is provided on the barrel clamping plate 18. The inner clamping bolt 23 is connected to the set screw hole 19 of the barrel clamping plate 18, and the end of the inner clamping bolt 23 abuts against the inner side of the vacuum hood barrel 9, locking and limiting the positioning seat 11 at a certain position on the vacuum hood 5, and thus completing the limitation of the position of the lateral adjustment component 1. The above structure can stably connect the tooling with the vacuum hood 5 and provide positioning support for other components, which is convenient to operate and ensures the stability of the operation process.

[0044] (2) Figures 8-10 The specific structure of the center alignment component 2 is schematically shown. As Figure 8 , Figure 9As shown in the figure, the center alignment component 2 includes a sliding seat 25. One side of the sliding seat 25 is provided with a centering arc 32, and the centering arc 32 is matched with the outer circle of the vacuum hood flange 10.

A U-shaped groove 30 is arranged in the middle of the sliding seat 25, and the U-shaped groove 30 is adapted to the outer shape of the boss at the upper end of the adapter block 26. Locking threaded holes 31 are symmetrically arranged on both sides of the U-shaped groove 30, and the adapter block 26 is fixed to the sliding seat 25 through fasteners. Waist-shaped holes 29 are arranged at the left and right ends of the sliding seat 25 for fixedly connecting with the substrate 13 in the lateral adjustment component 1. During the use of the tooling, the centering arc 32 of the sliding seat 25 is always in contact with the outer circle of the vacuum hood flange 10. Due to the arrangement of the waist-shaped holes 29 on the sliding seat 25, the position of the substrate 13 can be finely adjusted transversely relative to the sliding seat 25. After the bolt passes through the waist-shaped hole 29 and is screwed into the positioning screw hole 15 on the base 13, the sliding seat 25 is fixedly connected with the substrate 13, thereby realizing the determination of the lateral position of the lateral adjustment component 1 relative to the center alignment component 2. A concave groove is arranged on the lower-end boss of the adapter block 26, and the concave groove is adapted to the outer shape of the positioning block 27. The positioning block 27 is connected with the adapter block 26 through fasteners, and a alignment line 28 is arranged at the center position of the positioning block 27. As Figure 10 shown in the figure, when welding the feeding port 4, rotate the sliding seat 25 to make the center alignment component 2 rotate around the vacuum hood flange 10, so that the alignment line 28 of the positioning block 27 is transversely aligned with the center line 911 of the opening of the vacuum hood barrel (note: the center line 911 of the opening of the vacuum hood barrel is marked during the blanking and opening of the vacuum hood barrel), ensuring that the center line 61 of the pipe orifice of the feeding port pipe is transversely aligned with the center line 911 of the opening of the vacuum hood barrel. Moreover, the tooling can meet the welding requirements of feeding ports at different positions, is convenient to adjust, and improves the operation efficiency.

The guide sleeves 34 on both sides of the height-adjusting clamping component 3 respectively pass through the guide posts 12 of the horizontal adjusting component 1. The guide sleeve 34 can slide up and down along the guide post 12 to adjust the height of the feeding port 4. Adjust the height-adjusting bolts 41 on both sides of the support plate to adjust the feeding port 4 to the corresponding height, so that the screw end of the height-adjusting bolt 41 abuts against the substrate 13, and lock it with a lock nut 42 to stably maintain the feeding port 4 at the adjusted height position.
