Description

Technical Field

[0001] The utility model relates to the technical field of vacuum bellows, in particular to a vacuum bellows segment alignment device. Background Technique

[0002] A bellows refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescoping direction. Bellows are widely used in instruments and meters. Its main purpose is to be used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a relatively thin wall, high sensitivity, and a measurement range from dozens of pascals to dozens of megapascals. Its open end is fixed, and the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase elasticity.

[0003] During the processing of the bellows, it is necessary to weld the outer diameter of the bellows segments. When welding, in order to reduce the influence on adjacent segments, a copper ring is generally arranged between adjacent segments to play an isolation role. When it is necessary to fix a copper ring between adjacent vacuum bellows segments, two bellows segments are sleeved on the same straight rod, and a copper ring is placed between the two adjacent bellows segments. Then, the straight rod sleeved with the bellows segments is placed between two lower pressing rollers of the existing vacuum bellows segment alignment device, and then the upper pressing roller is pressed down. By the rolling of the lower pressing roller and the upper pressing roller, the copper ring can be completely embedded in the bellows segment, and such a device can be called a vacuum bellows segment alignment device.

[0004] However, when using such a vacuum bellows segment alignment device, the copper ring is simply embedded in the bellows segment by extrusion force, and the fixing strength is relatively low. Therefore, it does not meet the existing requirements, and for this reason, we propose a vacuum bellows segment alignment device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vacuum bellows segment alignment device to solve the problems mentioned in the above background technique, that is, when using such a vacuum bellows segment alignment device, the copper ring is simply embedded in the bellows segment by extrusion force, and the fixing strength is relatively low.

[0006] To achieve the above object, the present utility model provides the following technical solution: A vacuum bellows segment alignment device, comprising a base, wherein a slide rail is fixedly installed at the middle position of the upper end surface of the base, and a slide table is installed on both sides of the upper end surface of the slide rail. A vacuum bellows head fixing through hole penetrating the slide table is provided at the middle position of the front end surface of the slide table. An arc-shaped plate for fixing the pipe head is arranged inside the vacuum bellows head fixing through hole. A threaded rod is connected to the middle position of the upper end surface of the arc-shaped plate for fixing the pipe head through a roller bearing. The threaded rod vertically penetrates the slide table and is connected to the slide table through a threaded structure. A first guide rod whose lower end surface is fixed to the arc-shaped plate for fixing the pipe head is arranged on both sides of the threaded rod, and the first guide rod vertically and movably penetrates the slide table;

[0007] A square groove is arranged between the two slide tables. A lifting table is installed inside the square groove. A circular groove is provided on the upper side of the front end surface of the lifting table. A single-rod cylinder fixedly installed inside the lifting table is arranged behind the circular groove. The piston rod of the single-rod cylinder is connected to a pushing block. The upper and lower sides of the front end surface of the pushing block are both inclined surfaces. A fixing rod is arranged in front of the inclined surface. A copper ring located inside the circular groove is arranged on the outer sides of the top ends of the two fixing rods. A small industrial processing blowtorch fixedly installed on the inner wall of the lifting table is arranged in a circle outside the copper ring, and the flame nozzle on the small industrial processing blowtorch faces the copper ring.

[0008] Preferably, a control panel is fixedly installed on the outer surface of the base on one side of the slide rail, and the slide table, the lifting table, the small industrial processing blowtorch, and the single-rod cylinder are all electrically connected to the control panel.

[0009] Preferably, a second guide rod vertically movably penetrating the two fixing rods is arranged in front of the pushing block. Springs are sleeved on the upper and lower sides of the outer surface of the second guide rod, and the surfaces of the springs facing the fixing rods are connected to the fixing rods.

[0010] Preferably, a manual rotation handle is fixedly arranged on the upper end surface of the threaded rod, and the threaded rod is fixed to the manual rotation handle through a screw.

[0011] Preferably, the arc-shaped plate for fixing the pipe head is integrally arc-shaped, and the threaded rod is fixed to the first guide rod through a screw.

[0012] Preferably, a square cover plate is arranged on the upper end surface of the lifting table above the single-rod cylinder, and the lifting table is fixed to the square cover plate through a screw.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. When it is necessary to embed a copper ring in a corrugated pipe piece through this device, fix the two corrugated pipe pieces inside the two vacuum corrugated pipe head fixing openings respectively. Then fix the copper ring inside the circular groove on the front end face of the lifting table. After that, heat the copper ring with multiple small industrial processing blowtorches. When the copper ring is heated to over 110 degrees, turn off the small industrial processing blowtorches. Immediately move the corrugated pipe piece in front of the copper ring backward at this time, so that the rear end face thereof fits with the front end face of the copper ring. Due to the high temperature of the copper ring itself, it can melt the corrugated pipe head that fits with it and fix the two together. After the copper ring is fixed to the corrugated pipe piece in front of it, first move the corrugated pipe piece in front of the copper ring forward, then retract the lifting table, and move the corrugated pipe piece behind the copper ring forward. When the corrugated pipe piece behind the copper ring contacts the copper ring, it will also be fixed to the copper ring under the action of high temperature. Through the above technical solution, the fixing strength between the corrugated pipe piece and the copper ring is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] The threaded rod 6 (model number M20), the single-rod cylinder 13 (model number CQ2B), and the spring 18 (model number JX110) mentioned in the present utility model can all be obtained by purchasing from the market or customizing privately.

[0021] Please refer to Figures 1 to 3, an embodiment provided by the present utility model: a vacuum bellows segment alignment device, including a base 1. A slide rail 2 is fixedly installed at the middle position of the upper end face of the base 1. A slide table 3 is installed on both sides of the upper end face of the slide rail 2. A vacuum bellows head fixing through hole 4 penetrating the slide table 3 is provided at the middle position of the front end face of the slide table 3. An arc-shaped plate 5 for fixing the pipe head is arranged inside the vacuum bellows head fixing through hole 4. A threaded rod 6 is connected to the middle position of the upper end face of the arc-shaped plate 5 for fixing the pipe head through a roller bearing. The threaded rod 6 vertically penetrates the slide table 3 and is connected to the slide table 3 through a threaded structure. A first guide rod 7 whose lower end face is fixed to the arc-shaped plate 5 for fixing the pipe head is arranged on both sides of the threaded rod 6, and the first guide rod 7 vertically and movably penetrates the slide table 3;

[0022] A square groove 8 is arranged between the two slide tables 3. A lifting table 9 is installed inside the square groove 8. A circular groove 10 is arranged on the upper side of the front end face of the lifting table 9. A single-rod cylinder 13 fixedly installed inside the lifting table 9 is arranged behind the circular groove 10. The piston rod of the single-rod cylinder 13 is connected to a pushing block 14. The upper and lower sides of the front end face of the pushing block 14 are both inclined surfaces 15. A fixed rod 16 is arranged in front of the inclined surface 15. A copper ring 11 located inside the circular groove 10 is arranged outside the outer ends of the tops of the two fixed rods 16. A small industrial processing blowtorch 12 fixedly installed on the inner wall of the lifting table 9 is arranged in a circle outside the copper ring 11, and the flame heads on the small industrial processing blowtorch 12 face the copper ring 11; When it is necessary to embed the copper ring 11 into the bellows segment by this device, the two bellows segments to be embedded are respectively placed inside the two vacuum bellows head fixing through holes 4. Then, the threaded rod 6 located above the vacuum bellows head fixing through hole 4 is rotated. Driven by the threaded structure, the threaded rod 6 will move up and down accordingly. At this time, the threaded rod 6 is moved downward. As the threaded rod 6 descends, the arc-shaped plate 5 for fixing the pipe head connected thereto will move downward together. When the lower end face of the arc-shaped plate 5 for fixing the pipe head contacts the bellows segment located inside the vacuum bellows head fixing through hole 4, it can be fixed;

[0023] After a bellows piece is fixed inside each of the two vacuum bellows head fixing ports 4, place the copper ring 11 inside the circular groove 10 on the front end face of the lifting table 9 and sleeve it outside the two fixing rods 16. Then start the single-rod cylinder 13. At this time, push the pushing block 14 connected to it forward through the single-rod cylinder 13. As the pushing block 14 advances, the two inclined surfaces 15 on the front end face of the pushing block 14 will respectively contact the two fixing rods 16 and push the fixing rods 16 outwards. As the two fixing rods 16 move, the two fixing rods 16 will respectively contact the upper and lower sides of the inner wall of the copper ring 11 to fix the copper ring 11. When the copper ring 11 is fixed, adjust the overall height of the copper ring 11 through the lifting table 9. At this time, adjust the copper ring 11 to a height corresponding to the bellows head inside the vacuum bellows head fixing port 4. After the height adjustment of the copper ring 11 is completed, heat the copper ring 11 with a small industrial processing blowtorch 12. When the copper ring 11 is heated to over 110 degrees, turn off the small industrial processing blowtorch 12. Immediately move the bellows piece in front of the copper ring 11 backwards through the sliding table 3 so that the rear end face thereof fits with the front end face of the copper ring 11. Due to the high temperature of the copper ring 11 itself, it can melt the bellows head in contact with it and fix the two together. When the copper ring 11 is fixed to the bellows piece in front of it, first pull the pushing block 14 backwards through the single-rod cylinder 13 to release the fixation of the copper ring 11, and then move the bellows piece in front of the copper ring 11 forward to extract the copper ring 11 from the inside of the circular groove 10. Then retract the entire lifting table 9 into the square groove 8. Finally, move the bellows piece behind the copper ring 11 forward. When the bellows piece behind the copper ring 11 contacts the copper ring 11, it will also be fixed to the copper ring 11 under the action of high temperature. Through the above technical solution, the fixing strength between the bellows piece and the copper ring 11 is improved.

[0024] One side of the sliding rail 2 is provided with a control panel 19 fixedly installed on the outer surface of the base 1, and the sliding table 3, the lifting table 9, the small industrial processing blowtorch 12 and the single-rod cylinder 13 are all electrically connected to the control panel 19; through the control panel 19, the sliding table 3, the lifting table 9, the small industrial processing blowtorch 12 and the single-rod cylinder 13 can be controlled.

[0025] A second guide rod 17 vertically passes through the two fixing rods 16 in front of the pushing block 14. Springs 18 are sleeved on the upper and lower sides of the outer surface of the second guide rod 17, and the surfaces of the springs 18 facing the fixing rods 16 are connected to the fixing rods 16; when the fixing rods 16 are pushed outwards, the springs 18 connected to them will be compressed. When the pushing block 14 is pulled backwards through the single-rod cylinder 13, due to the reaction force of the compressed springs 18, the fixing rods 16 can be pushed inwards to release the fixation of the copper ring 11.

[0026] The upper end face of the threaded rod 6 is fixedly provided with a manual rotating handle, and the threaded rod 6 and the manual rotating handle are fixed by screws; thus, the threaded rod 6 can be rotated more conveniently through the manual rotating handle.

[0027] The arc-shaped plate 5 for pipe head fixing is integrally arc-shaped, and the threaded rod 6 and the first guide rod 7 are fixed by screws; through the arc-shaped plate 5 for pipe head fixing which is integrally arc-shaped, the contact area between the arc-shaped plate 5 for pipe head fixing and the corrugated sheet can be increased, so as to improve the fixing strength of the corrugated sheet.

[0028] Above the single-rod cylinder 13, there is a square cover plate located on the upper end face of the lifting platform 9, and the lifting platform 9 and the square cover plate are fixed by screws; through the square cover plate, the internal structure of the lifting platform 9 can be protected, and when a failure occurs in the internal structure of the lifting platform 9, the square cover plate can be removed to repair its internal structure.
