Description

Technical Field

[0001] This invention relates to a multi-angle laser engraving fixture for a water-cooled housing. Background Technology

[0002] The water-cooled motor housing is formed by welding a water-cooling shell around the motor. After welding, the water-cooled motor housing needs to be laser-etched at multiple different angles on its surface. Specialized clamps are required to hold the water-cooled motor housing during welding. Chinese Patent 201520378798.3 also disclosed a novel laser-etching error-proofing fixture, including: a position positioning fixture, a wire clamping fixture, and a wire-supporting fixture base. The position positioning fixture includes: a base and a first position positioning module and a second position positioning module mounted on the base. The wire-supporting fixture base is equipped with a wire-supporting fixture, a position sensor, and a controller. The controller is connected to the position sensor and a laser generator, respectively. This invention presents a novel laser-etching error-proofing fixture.

[0003] The fixture uses sensors and a controller to replace manual judgment, avoiding human error. However, this invention cannot meet the requirements of the special shape of a water-cooled motor housing, nor can it complete engraving at different angles, making it inconvenient to use. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a multi-angle laser marking fixture for water-cooled housings that can stably clamp the housing and perform laser marking at different angles.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-angle laser marking fixture for a water-cooled housing, comprising a base, a rotating shaft rotatably disposed on the base, a rotating handle disposed at one end of the rotating shaft, and a rotating seat disposed at the other end of the rotating shaft, characterized in that the rotating seat is provided with a plurality of support seats for supporting the water-cooled housing, and the rotating seat is also provided with a plurality of clamping mechanisms for clamping the edge of the water-cooled housing and corresponding one-to-one with the support seats, the plurality of clamping mechanisms being arranged in a ring around the periphery of the water-cooled housing; the rotating seat is provided with a plurality of first through holes corresponding one-to-one with the areas to be marked, the base is provided with a second through hole through which a directional pin passes, the directional pin passing through the second through hole and then through one of the first through holes; the base is provided with a plurality of label lines corresponding to the areas to be marked, the rotating handle is provided with a rotating disk, the label lines are disposed around the rotating disk, and the rotating disk is provided with a pointer needle that can point to the label lines.

[0006] Preferably, in the above-mentioned multi-angle laser engraving fixture for water-cooled housing, the rotating base is provided with a positioning shaft extending into the inner cavity of the water-cooled housing.

[0007] Preferably, in the above-mentioned multi-angle laser engraving fixture for water-cooled housing, the rotating base is provided with multiple rotating grips.

[0009] Preferably, in the above-mentioned multi-angle laser engraving fixture for water-cooled housing, the clamping mechanism includes a pressure handle, a base plate fixed on the rotating seat, and an L-shaped plate fixed on the base plate. A connecting plate is rotatably provided on the top of the L-shaped plate, and a connecting arm is provided on the top of the connecting plate. The end of the connecting arm is connected to a clamping block for clamping the edge of the water-cooled housing through a height fine-adjustment device. A first inclined plate is provided on the end of the pressure handle and rotatably connected to the connecting plate.

[0014] The main technical advantages of this invention are as follows: multiple clamping mechanisms are arranged in a ring around the periphery of the water-cooled housing. This ring arrangement is compatible with the cylindrical shape of the water-cooled housing, ensuring its fixation. Rotating the rotating handle allows the pointer to point to the label line. When the pointer aligns with the label line, the corresponding marking area is located directly below the laser engraving machine. This easily determines the position of multiple marking areas, providing convenience for workers and simplifying operation. Once the marking area is determined, the directional pin passes through the second through hole and then through the corresponding first through hole, fixing the rotating seat in place and preventing it from rotating on its own and affecting the marking effect.

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, a multi-angle laser engraving fixture for a water-cooled housing includes a base 11, on which a rotating shaft 12 is rotatably disposed. A rotating handle 13 is welded to one end of the rotating shaft 12, and a rotating seat 14 is welded to the other end of the rotating shaft 12.

[0024] Four support seats 10 for supporting the water-cooled housing 1 are welded on the rotating seat 14. Four pressing mechanisms 5 for pressing the edge of the water-cooled housing 1 and corresponding to the support seats 10 are also provided on the rotating seat 14. The four pressing mechanisms 5 are arranged in a ring around the water-cooled housing 10.

[0025] The rotating base 14 has multiple first through holes 41 corresponding to the marking areas 100. The base 11 has a second through hole through which a directional pin 42 passes. The directional pin 42 passes through the second through hole and then through one of the first through holes 41. The base 11 has multiple label lines 45 corresponding to the marking areas 100. A rotating disk 46 is fixedly mounted on the rotating handle 13. The label lines 45 are located around the rotating disk 46. The rotating disk 46 has a pointer pin 47 that can point to the label lines 45. In this invention, there are 4 marking areas, 4 corresponding first through holes 41, and 4 label lines 45.

[0026] The main technical effects of this invention are as follows: multiple clamping mechanisms 5 are arranged in a ring around the periphery of the water-cooled housing 1. This ring arrangement is compatible with the cylindrical shape of the water-cooled housing 1, ensuring that the water-cooled housing 1 is fixed. By rotating the rotating handle 13, the pointing needle 47 can be directed to the label line 45. When the pointing needle 47 and the label line 45 correspond, the corresponding marking area 100 is located directly below the laser marking machine. This easily achieves the determination of the position of multiple marking areas 100, bringing many conveniences to the workers and making the operation relatively simple. After the marking area 100 is determined, the directional pin 42 passes through the second through hole 41 and then through the corresponding first through hole, which can fix the rotating seat 14 and prevent the rotating seat 14 from rotating on its own and affecting the marking effect.

[0027] In this invention, a positioning shaft 61 extending into the inner cavity of the water-cooled housing 1 is welded to the center of the rotating base 14. This design makes the water-cooled housing 1 more stably fixed on the rotating base 14.

[0028] The outer wall of the rotating seat 14 in this invention is welded with a plurality of rotating grip rings 90. The rotating grip rings 90 are evenly distributed on the outer wall, and the rotating grip rings 90 can be gripped by hand, making it more convenient to rotate or stop the rotating seat 14.

[0029] The clamping mechanism 5 of this invention includes a clamping handle 51, a base plate 52 fixed to the rotating seat 14 by screws, and an L-shaped plate 53 welded to the base plate 52. The clamping handle 51 is provided with an anti-slip sleeve 500 for anti-slip purposes. A connecting plate 54 is rotatably mounted on the top of the L-shaped plate 53, and a connecting arm 55 is mounted on the top of the connecting plate 54. The end of the connecting arm 55 is connected to a clamping block 56 for clamping the edge of the water-cooled housing 1 via a height fine-tuning device 7. A first inclined plate 57 is rotatably connected to the connecting plate 54 at the end of the clamping handle 51. A second inclined plate 58 is rotatably mounted on the bottom plate of the L-shaped plate 53 and rotatably connected to the first inclined plate 57. The rotatable connection can be a hinged connection. The connecting plate 54 and the connecting arm 55 are integrally formed and vertically arranged. The operator can clamp or release the clamping block 56 by lifting or pressing the clamping handle 51. The clamping mechanism 5 of this invention has the following advantages: 1. The workpiece can be quickly clamped or released by simply pressing down or lifting the handle 51, without the need for complex tools or multiple adjustments, greatly improving operational efficiency; 2. A "dead point" effect is generated when it is close to the closed position, so the clamp can still maintain the clamped state even if the external force is removed, without the need for continuous force application; 3. The clamping force is much greater than the force applied manually, usually several times or even more than ten times, ensuring that the workpiece remains stable during processing; 4. The height fine-tuning device 7 can finely adjust the position of the clamping block 56 to adapt to clamping workpieces of different thicknesses.

[0030] The height fine-tuning device 7 of this invention includes a threaded post 71 passing through the connecting arm 55 and connected to the clamping block 56, a first limiting plate 72 and a second limiting plate 73 disposed on the threaded post 71, the connecting arm 55 being clamped between the first limiting plate 72 and the second limiting plate 73, and a nut 74 threadedly connected to the threaded post 71 on the outer side of the first limiting plate 72 and the first limiting plate 73, respectively. By rotating the nut 74, the user can move the first limiting plate 72 and the second limiting plate 73, thereby adjusting the relative position of the connecting arm 55 and the clamping block 56. This device is convenient to use and has a simple structure.

[0031] The directional pin 42 in this invention includes a pin shaft 91 and a ring 92 connected to the pin shaft 91, which facilitates insertion and removal by workers.

[0032] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
