Description

Technical Field

[0001] The utility model relates to the field of vacuum welding, in particular to a target material welding tool. Background Art

[0002] During the preparation of the target material, electron beam welding is required to connect the two target materials. Since the welding processes required for targets of different specifications and materials are different, the welding process parameters need to be adjusted through trial production. When welding the target material, the target material needs to be clamped. Since there are many types of trial-produced target materials, a large number of customized fixtures need to be made to fix the target material.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Example 1

[0026] refer to Figure 1-5 A target welding tool comprises a clamping unit 1 and a base 2. A sliding block 3 and a first driving module 4 are provided on the base 2. A gradually narrowing boss 11 is provided at the bottom of the clamping unit 1. The sliding blocks 3 are symmetrically arranged on both sides of the boss 11, and the contour surface of the boss 11 contacts the sliding blocks 3. The first driving module 4 is used to drive the sliding blocks 3 to move closer to or away from each other to drive the boss 11 to rise and fall so as to realize the lifting and lowering of the clamping unit 1.

[0027] In this embodiment, the sliding blocks 3 are used in pairs. This embodiment uses two pairs of sliding blocks 3, and multiple pairs of sliding blocks 3 can also be set according to actual needs. The two pairs of sliding blocks 3 are respectively abutted on the boss 11. The specific use process of the target welding tooling is: first fix the base 2 on the external electron beam welding equipment, and then use the clamping unit 1 to clamp the target material. The first driving module 4 drives the sliding blocks 3 to move closer or farther from each other, and the contour surface of the boss 11 contacts the sliding block 3. When the sliding block 3 moves, it always abuts against the contour surface of the boss 11, and the boss 11 gradually narrows. The boss 11 will move up and down with the movement of the sliding block 3, thereby realizing the lifting and lowering of the clamping unit 1.

[0028] The clamping unit 1 can be raised and lowered by using the sliding blocks 3 to move closer to or further away from each other. The advantages are: first, the clamping unit 1 can be raised and lowered smoothly, which is convenient for the staff to adjust the height of the target material; second, after the height is adjusted, the clamping unit 1 is not prone to up and down deviation, ensuring that the target material is always at this height, thereby improving the welding quality.

[0029] Preferably, the shape of the boss 11 is an arc, an isosceles triangle or an isosceles trapezoid.

[0030] In this embodiment, the shape of the boss 11 is preferably an arc, and other shapes may be selected according to actual needs. The sliding block 3 can move more smoothly on the arc surface.

[0031] Preferably, the sliding block 3 is provided with a roller 31 ; the sliding block 3 abuts against the boss 11 via the roller 31 .

[0032] In this embodiment, in order to reduce the friction between the sliding block 3 and the boss 11, a roller 31 is provided on the sliding block 3. When the first driving module 4 drives the sliding block 3 to move, the sliding block 3 contacts the boss 11 through the roller 31, which can reduce friction, make the boss 11 rise and fall more smoothly, and also facilitate the operation of the staff.

[0033] Preferably, the first driving module 4 includes a double-headed screw 41 and a handwheel 42; the symmetrically arranged sliding blocks 3 are respectively threadedly connected to the two ends of the double-headed screw 41; the double-headed screw 41 is rotatably connected to the base 2; and the handwheel 42 is connected to the end of the double-headed screw 41.

[0034] In this embodiment, the first driving module 4 includes a double-ended screw 41 and a hand wheel 42. The double-ended screw 41 is used in pairs with the sliding block 3. In other words, each double-ended screw 41 is symmetrically provided with a pair of sliding blocks 3. The double-ended screw 41 is rotatably provided on the base 2. The staff rotates the hand wheel 42 to drive the double-ended screw 41 to rotate, thereby driving the sliding blocks 3 to move closer to or away from each other. When multiple double-ended screws 41 are provided, a hand wheel 42 can be provided on each double-ended screw 41, or multiple double-ended screws 41 can be connected by a synchronous belt or chain.

[0035] Preferably, the base 2 is provided with a first slide rail 21 ; the slide block 3 is slidably connected to the first slide rail 21 .

[0036] In this embodiment, in order to ensure that the sliding block 3 can move smoothly, a first slide rail 21 is set on the base 2, and the sliding block 3 is slidably connected to the first slide rail 21, which can not only keep the sliding block 3 moving straight, but also the first slide rail 21 can share the weight of the clamping unit 1 supported by the sliding block 3, thereby improving the service life of the sliding seat.

[0037] Preferably, the clamping unit 1 includes a fixed seat 12, a movable seat 13, a second driving module 14 for driving the movable seat 13 to move closer to or away from the fixed seat 12, and a support plate 15; the boss 11 is arranged at the bottom of the support plate 15; the fixed seat 12 is placed on the support plate 15; the movable seat 13 is slidably connected to the support plate 15; the fixed seat 12 and the movable seat 13 are both provided with a groove 16 for placing the target material.

[0038] In this embodiment, the specific working process of the clamping unit 1 is as follows: the staff first estimates the size of the target material, adjusts the distance between the movable seat 13 and the fixed seat 12 through the second driving module 14, and then places the target material in the groove 16. The staff then drives the movable seat 13 to move through the second driving module 14, so that the movable seat 13 presses the target material.

[0039] Preferably, the base 2 is provided with a guide shaft 22 ; the support plate 15 is slidably connected to the guide shaft 22 .

[0040] In this embodiment, in order to make the lifting of the clamping unit 1 more stable, by providing a guide shaft 22, when the sliding block 3 drives the support plate 15 to be lifted or lowered, the support plate 15 can be lifted or lowered in the vertical direction without being deflected or rotated.

[0041] Preferably, the support plate 15 is provided with a second slide rail 17 ; the movable seat 13 is slidably connected to the second slide rail 17 to achieve a slidable connection with the support plate 15 .

[0042] In this embodiment, the movable seat 13 can move more smoothly by providing the second slide rail 17. The second driving module 14 is preferably a screw and a hand wheel with a handle. The movable seat 13 is threadedly connected to the screw, and the staff rotates the hand wheel with a handle to rotate the screw, thereby driving the movable seat 13 to move toward the fixed seat 12.

[0043] Preferably, both sides of the support plate 15 are provided with side plates 18 ; the side plates 18 are provided with strip holes 181 ; both sides of the movable seat 13 are provided with studs 131 ; the studs 131 pass through the strip holes 181 and are locked by nuts to limit the movement of the movable seat 13 .

[0044] In this embodiment, after the movable seat 13 clamps the target material, the nut is inserted into the stud 131 and tightened to fix the movable seat 13 to prevent the movable seat 13 from loosening during welding and causing the target material to shift, thereby affecting welding.

[0045] Preferably, scales 19 are provided on both sides of the support plate 15 ; pointers 132 are provided on both sides of the moving seat 13 ; the pointers 132 point to the scales 19 to control the moving distance of the moving seat 13 .

[0046] In this embodiment, the staff can move the movable seat 13 to the corresponding scale according to the ruler 19 when moving the movable seat 13 in advance according to the size of the target material, so that when the target material is placed subsequently, the target material can be directly overlapped on the groove 16. The staff only needs to move the movable seat 13 again without holding the target material with hands, thereby reducing the work intensity of the staff.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
