Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and in particular to a self-rotating fixing device for laser welding equipment. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that utilizes a high-energy-density laser beam as a heat source. It is a crucial application of laser materials processing technology. In the 1970s, it was primarily used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type; the laser radiation heats the workpiece surface, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the laser pulse width, energy, peak power, and repetition frequency, the workpiece melts, forming a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] According to the existing technology CN2024116672197, due to the special nature of the product, it is necessary to process one ring. However, in order to match the quality of laser welding, the product needs to be pressed and fixed completely. Existing general tooling can only press one side, and after being fully pressed, it cannot be rotated, so it is impossible to weld the other side, thus affecting the welding efficiency.

[0004] Therefore, it is necessary to design a self-rotating fixing device for laser welding equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a self-rotating fixing device for laser welding equipment, so as to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-rotating fixing device for laser welding equipment includes a fixed base, a first machining center turntable connected to the fixed base via a first rotating motor and horizontally connected to the fixed base, a rotating shaft seat disposed on the first machining center turntable, a second machining center turntable connected to the first rotating motor and mounted at the front end of the rotating shaft seat, a product mounting fixture mounted on the second machining center turntable, and a product fixing assembly disposed on the rotating shaft seat. The product fixing assembly includes a mounting seat mounted on the rotating shaft seat, an elbow clamp disposed on the mounting seat and above the product mounting fixture, a ball bearing mounting block disposed at the end of the elbow clamp, a plurality of balls disposed on the ball bearing mounting block, a pressure block disposed at the bottom of the ball bearing mounting block, and a protective shell sleeved on the ball bearing mounting block and connected to the ball bearing mounting block by bolts. A circular groove is formed on the top of the pressure block, and a first bearing sleeved on the elbow clamp is installed inside the pressure block.

[0008] Preferably, the balls on the ball mounting block are evenly distributed in a circle around the center of the ball mounting block, and each group of balls falls into the circular groove of the pressure block.

[0009] Preferably, a second bearing is provided inside the ball bearing mounting block.

[0010] Preferably, a spring is also sleeved outside the lower pressure shaft of the elbow clamp, and the bottom of the spring supports the ball bearing mounting block, while the top of the spring supports the base of the elbow clamp.

[0011] Preferably, guide posts are also provided on both sides of the mounting base.

[0012] The beneficial effects of this utility model are: by setting two-dimensional drive motors, the position of the processed product can be adjusted to adapt to different angles for processing, and by setting two sets of bearings and ball bearings, the stability of the product installation fixture rotation is ensured.

[0017] Reference Figures 1 to 3A self-rotating fixing device for laser welding equipment includes a fixed base 1, a first machining center turntable 3 connected to the fixed base via a first rotating motor 2 and horizontally connected to the fixed base, a rotating shaft seat 4 disposed on the first machining center turntable, a second machining center turntable 6 connected to the front end of the rotating shaft seat via a second rotating motor 5, a product mounting fixture 7 disposed on the second machining center turntable, and a product fixing assembly 8 disposed on the rotating shaft seat.

[0018] The product fixing assembly 8 includes a mounting base 81 mounted on the rotating shaft seat, an elbow clamp 82 disposed on the mounting base and above the product mounting fixture, a ball bearing mounting block 83 disposed at the end of the elbow clamp 82, a plurality of balls 84 disposed on the ball bearing mounting block, a pressure block 85 disposed at the bottom of the ball bearing mounting block, and a protective shell 86 sleeved on the ball bearing mounting block and connected to the ball bearing mounting block by bolts;

[0019] A circular groove 851 is provided on the top of the pressure block 85. The balls 85 provided on the ball mounting block are evenly distributed in a circle around the center of the ball mounting block, and each group of balls falls into the circular groove of the pressure block.

[0020] In order to accommodate the rotation of the product while the elbow clamp at the top does not rotate, a first bearing 11 sleeved on the outside of the elbow clamp is installed in the pressure block 85, and a second bearing 12 is provided in the ball bearing mounting block 83. The first bearing and the second bearing interact with each other to ensure balanced pressure and ensure the stability of rotation.

[0021] A spring 13 is also sleeved outside the pressing shaft of the elbow clamp, with the bottom of the spring supporting the ball bearing mounting block and the top supporting the base of the elbow clamp, so that the elbow clamp has a certain elasticity when it is pressed down, thus having a certain degree of floating.

[0022] To facilitate the guidance of the elbow clamp, guide posts 14 are provided on both sides of the mounting base to facilitate the up-and-down movement of the elbow clamp for fixation.

[0023] In this implementation, the product to be welded is placed on the product mounting fixture 7, and then the elbow clamp is pressed down, causing the pressure block 85 to move down and hold the product in place, thus fixing the product. The first rotary motor drives the rotating shaft seat 4 to rotate horizontally, achieving the first dimension of adjustment. Then, the second rotary motor 5 drives the entire product mounting fixture 7 to rotate, thereby achieving the second dimension of adjustment. Through these two sets of adjustments, welding can be performed on all four sides of the product. In order to achieve product rotation in the fixture while the elbow clamp does not rotate, the two do not interfere with each other.

[0024] Specifically, the second rotary motor drives the second processing platform turntable 6 to rotate, thereby driving the product mounting fixture 7 to rotate. Since the pressure block 85 presses down on the product, and since the first bearing 11 is installed inside the pressure block 85, the pressure block rotates synchronously after the product mounting fixture 7 is driven to rotate. In order to ensure the stability of the pressure block's rolling and to ensure that the pressure block does not affect the use of other components, the circular groove rotates synchronously after the pressure block rotates, and the balls 84 of the ball mounting block roll in coordination with the rotation.

[0025] The advantages of this utility model are that by setting two-dimensional drive motors, the position of the processed product can be adjusted to adapt to different angles for processing. Furthermore, by setting two sets of bearings and ball bearings, the stability of the product's rotation when mounted on the fixture is ensured.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
