Description

Technical Field

[0001] This utility model relates to the field of friction welding technology, and in particular to a workpiece friction welding positioning device. Background Technology

[0002] Friction welding is a method of welding that utilizes the heat generated by friction between the contact surfaces of workpieces as a heat source, causing the workpieces to undergo plastic deformation under pressure. Positioning is a crucial step in friction welding; without proper positioning and fixation, the weld quality will deteriorate due to thermal deformation and uneven stress during the welding process. Therefore, a positioning device is required in friction welding.

[0003] Most existing positioning devices fix the clamp to the connecting plate, and then fix the connecting plate to the worktable. Since these connection positions are fixed, their positions cannot be adjusted. Consequently, most of these positioning devices can only perform welding positioning at right angles or specific angles, which cannot meet the diversity of friction welding positioning. Utility Model Content

[0004] This invention provides a workpiece friction welding positioning device, which solves the technical problem that existing positioning devices cannot meet the diverse welding angle requirements.

[0005] To achieve this technical objective, the present invention adopts the following solution: a workpiece friction welding positioning device includes a worktable, a fixing block, a connecting plate, and a clamp;

[0006] The workbench includes a platform and a side plate fixedly installed at the end of the platform, the side plate extending vertically;

[0007] The fixing block is magnetically and detachably mounted on the platform and / or side panel;

[0008] Both ends of the connecting plate are rotatably connected to the fixed block;

[0009] The clamp is set on the bottom surface of the connecting plate and is used to fix the workpiece to be welded.

[0010] Furthermore, the fixing block includes a housing and a top cover;

[0011] The two opposite side walls of the box are provided with through slots. The box contains an installation box. The two opposite side walls of the installation box are provided with clearance slots corresponding to the positions of the through slots. The installation box contains magnetic blocks.

[0012] One end of the rocker is set at the bottom of the magnetic block. The rocker extends to the outside of the box by passing through the clearance groove and the through groove in sequence. The rocker is rotatably connected to the outer wall of the mounting box.

[0013] Furthermore, symmetrically distributed mounting blocks are provided on both sides of the through groove, and limit rods are inserted into the mounting blocks.

[0014] Furthermore, a ball-shaped sleeve is fixed to the top surface of the cover.

[0015] Furthermore, universal ball joints are fixed at both ends of the connecting plate, and the universal ball joints are inserted into the ball joint sleeves;

[0016] The bottom surface of the connecting plate has a mounting groove for installing the clamp.

[0017] Furthermore, the clamp includes a clamping plate, an anti-slip pad, and a nut. A screw is fixed at one end of the clamping plate. The screw passes through the anti-slip pad and the mounting groove in sequence and extends to the other side of the connecting plate. The nut is threaded on the screw and abuts against the connecting plate.

[0018] The anti-slip pad is installed inside the mounting groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The fixed block in the workpiece friction welding positioning device disclosed in this utility model is connected to the platform and side wall by magnetic attraction, which can conveniently adjust the position of the fixed block, thereby adjusting the position and angle of the connecting plate and the clamp on it, thereby adjusting the position and angle of the workpiece to meet the positioning requirements of friction welding under various conditions.

[0021] 2. A rocker arm is installed inside the fixing block. When the position of the fixing block needs to be adjusted, simply press one end of the rocker arm, and the other end will lift the magnetic block, separating it from the worktable, allowing the fixing block to be removed from the worktable. This is more convenient and less strenuous than directly pulling the fixing block off the worktable. Attached Figure Description

Detailed Implementation

[0030] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0031] like Figures 1 to 6 As shown, the workpiece friction welding positioning device provided by this utility model includes a worktable 1, a fixing block 2, a connecting plate 3, and a clamp 4. The worktable 1 is made of iron plate and includes a platform 11 and a side plate 12 fixedly disposed at the end of the platform 11, the side plate 12 extending vertically.

[0032] The fixing block 2 is detachably mounted on the platform 11 and / or side plate 12 by magnetic attraction. The fixing block 2 includes a housing 21 and a top cover 22, with the top cover 22 fixedly mounted on the top of the housing 21. Two opposite side walls of the housing 21 are provided with through slots 222. An installation box 221 is located inside the housing 21. Two opposite side walls of the installation box 221 are provided with clearance slots 223 corresponding to the positions of the through slots 222. A magnetic block 224, made of permanent magnet, is located inside the installation box 221. One end of a rocker arm 225 is located at the bottom of the magnetic block 224. The rocker arm 225 extends through the clearance slots 223 and through slots 222 to the outside of the housing 21, and is rotatably connected to the outer side wall of the installation box 221. Symmetrically distributed installation blocks 226 are provided on both sides of the through slots 222, and a limiting rod 227 is inserted into each installation block 226.

[0033] The principle behind the magnetic attraction of the fixing block 2 to the worktable 1 is as follows: the magnetic block 224 is placed inside the mounting box 221, and under the influence of the magnetic field, the magnetic block 224 is magnetically attracted to the worktable 1, thereby fixing the fixing block 2 to the worktable 1. The fixing block 2 can be made of non-magnetic metals such as copper or aluminum. When it is necessary to remove the fixing block 2 from the worktable 1, simply press down on one end of the rocker arm 225 located outside the box 21. At this time, the rocker arm 225 rotates around the rotational connection point between the rocker arm 225 and the mounting box 221, causing the rocker arm 225 below the magnetic block 224 to move upward, thereby lifting the magnetic block 224 and separating the fixing block 2 from the worktable 1. To prevent the magnetic block 224 from being accidentally attracted to the worktable 1, it is necessary to keep the rocker 225 tilting the magnetic block 224. At this time, simply insert the limiting rod 227 into the mounting block 226 and press the limiting rod 227 against the top of the rocker 225 located outside the housing 21 to prevent it from rotating.

[0034] Both ends of the connecting plate 3 are rotatably connected to the fixing block 2. In one embodiment, a ball head sleeve 5 is fixedly provided on the top surface of the upper cover 22. Both ends of the connecting plate 3 are fixedly provided with universal ball heads 6, which are inserted into the ball head sleeve 5.

[0035] The clamp 4 is disposed on the bottom surface of the connecting plate 3 and is used to fix the workpiece to be welded. In one embodiment, the bottom surface of the connecting plate 3 has a mounting groove 31 for mounting the clamp 4. The clamp 4 includes a clamping plate 41, an anti-slip pad 42, and a nut 43. A screw 44 is fixed to one end of the clamping plate 41, passing through the anti-slip pad 42 and the mounting groove 31 in sequence and extending to the other side of the connecting plate 3. The nut 43 is threaded onto the screw 44 and abuts against the connecting plate 3. The anti-slip pad 42 is disposed within the mounting groove 31. In use, simply tightening the nut 43 is sufficient to fix the clamping plate 41 onto the connecting plate 3.

[0036] In use, first adjust the positions of the two fixing blocks 2 so that the connecting plate 3 is at a suitable angle. Then, place the workpiece to be welded between the connecting plate 3 and the clamping plate 41, and then tighten the nut 43 to stably clamp the workpiece between the clamping plate 41 and the connecting plate 3. During the positioning process, multiple positioning devices can be used to firmly position the workpiece in the appropriate welding position, and then friction welding can be performed.

[0037] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
