[0028] Example 1

[0029] A preferred embodiment of the triaxial displacement fixture for welding automotive workpieces provided by this utility model is as follows: Figures 1 to 6 The image shows a three-axis displacement fixture for welding automotive workpieces, comprising a base frame 1, first slide rails 2 fixed at the front and rear ends of the top of the base frame 1, with first sliders 3 slidably connected to the left and right sides of the outer side of the first slide rails 2; a first slide block 4 fixed to the outer wall of the first slider 3, a first mounting plate 5 fixed to the top of the first slide block 4, and a mounting bracket 6 fixed to the top of the first mounting plate 5; second slide rails 7 fixed to the left and right sides of the top of the mounting bracket 6, with second sliders 8 slidably connected to the front and rear ends of the outer side of the second slide rails 7; a second slide block 9 fixed to the outer side of the second slider 8, a second mounting plate 10 fixed to the top of the second slide block 9, and a bracket 11 fixed to the top of the second mounting plate 10, with a slide 12 mounted on the top of the bracket 11; a lateral displacement assembly 13 mounted on the top of the base frame 1; a longitudinal displacement assembly 14 mounted on the top of the mounting bracket 6; and a lifting assembly 15 mounted on the top of the bracket 11.

[0030] The lateral displacement component 13 controls the mounting bracket 6 to move along the direction of the first slide rail 2. The lateral displacement component 13 includes a first motor 1301 fixed to the top left side of the base frame 1, and a first rotating shaft 1302 fixed to the output end of the first motor 1301 is rotatably connected to the base frame 1; a first sleeve 1303 threadedly sleeved outside the first rotating shaft 1302, and the first sleeve 1303 is slidably connected to the base frame 1; and a first connecting frame 1304 fixed to the outside of the first sleeve 1303, and the first connecting frame 1304 is fixedly connected to the first mounting plate 5 on the right side. The longitudinal displacement component 14 can move the bracket 11 along the direction of the second slide rail 7. The longitudinal displacement component 14 includes a first motor 1301 fixed to the top left side of the mounting bracket 6. The second motor 1401 is located at one end, and the second rotating shaft 1402 fixed at the output end of the second motor 1401 is rotatably connected to the mounting bracket 6; the second sleeve 1403 is threaded onto the outside of the second rotating shaft 1402, and the second connecting bracket 1404 is fixedly connected to the bracket 11; the lifting assembly 15 can control the slide 12 to perform lifting and lowering operations; the lifting assembly 15 includes a slide rod 1501 slidably disposed at the four corners inside the bracket 11, and the slide rod 1501 is fixedly connected to the slide 12; the first electric cylinder 1502 is fixedly disposed at the front and rear ends of the top of the bracket 11, and the output end of the first electric cylinder 1502 is fixedly connected to the bottom of the slide 12.

[0031] It should be noted that the existing three-axis displacement fixtures for welding automotive parts still have certain shortcomings in actual use. They cannot move the positioned workpiece along the three axes, which reduces the accuracy of the welding area of ​​the workpiece and the welding machine.

[0032] In this embodiment, the workpiece is first placed on top of the slide 12. The operation of the first motor 1301 controls the rotation of the first rotating shaft 1302. Through the threaded transmission design between the first rotating shaft 1302 and the first sleeve 1303, the first sleeve 1303 drives the first connecting frame 1304 and the first mounting plate 5, in conjunction with the first slider 3 and the first slide block 4, along with the mounting frame 6, the bracket 11, and the slide 12, to move along the direction of the first slide rail 2. Then, the operation of the second motor 1401 causes the second motor 1401 to... 401 controls the rotation of the second rotating shaft 1402. Through the threaded transmission design between the second rotating shaft 1402 and the second sleeve 1403, the second sleeve 1403 drives the second connecting frame 1404 and the second mounting plate 10, in conjunction with the second slider 8 and the second slide block 9, along with the bracket 11 and the slide 12, to move along the direction of the second slide rail 7. Furthermore, by using the first electric cylinder 1502, the slide 12 is raised or lowered along the direction of the bracket 11 or in the opposite direction. In this way, the workpiece is displaced in the X, Y, and Z axes. In addition, the slide rod 1501 improves the stability of the slide 12 during raising and lowering.

[0033] In a further preferred embodiment of this utility model, a frame 16 is provided on the left side of the base frame 1, a PLC controller 17 is fixed inside the frame 16, and a welding machine 18 is provided outside the frame 16. The PLC controller 17 is connected to the first motor 1301, the second motor 1401, the first electric cylinder 1502 and the welding machine 18 through wires. The first motor 1301 and the second motor 1401 are servo motors.

[0034] In this embodiment, the PLC controller 17 controls the first motor 1301, the second motor 1401, and the first electric cylinder 1502 to precisely control the workpiece in the three-axis displacement within the welding point area of ​​the welding machine 18, thus ensuring the stability of the precise welding between the nut and the workpiece.

[0035] Example 2

[0036] Based on Embodiment 1, a preferred embodiment of the triaxial displacement fixture for welding automotive workpieces provided by this utility model is as follows: Figures 1 to 6 As shown: Positioning pins 19 are fixed on the left and right sides of the top of the slide 12. Shock-absorbing springs 20 are fixed at the four corners of the bottom of the slide 12 and are fixedly connected to the bracket 11. Several second electric cylinders 21 are fixed from left to right at the bottom of the slide 12. The second electric cylinders 21 are connected to the PLC controller 17 through wires. The output end of the second electric cylinder 21 slides through the slide 12. The output end of the second electric cylinder 21 is fixed with a clamping plate 22. Several covers 23 are provided on the top of the base frame 1 and the mounting frame 6. The cover 23 has a clearance hole 24 integrally provided inside. The cross-section of the first slide 4, the second slide 9, the first connecting frame 1304 and the second connecting frame 1404 is U-shaped.

[0037] In this embodiment, when the workpiece is placed on top of the slide 12, the positioning hole pre-set inside the workpiece fits the positioning pin 19, thereby positioning the workpiece. Then, by using the second electric cylinder 21, the second electric cylinder 21 drives the clamping plate 22 to apply clamping force to the workpiece, thereby locking the workpiece in the position at the top of the slide 12. The clearance hole 24 allows for the displacement space of the first slide 4, the second slide 9, the first connecting frame 1304, and the second connecting frame 1404. The cover 23 can isolate the first slide rail 2, the second slide rail 7, the first slide 4, the second slide 9, the first rotating shaft 1302, and the second rotating shaft 1402 from the outside. The shock-absorbing spring 20 can buffer the vibration generated when the slide 12 is raised and lowered.

[0038] In summary, this application can move the positioned workpiece along three axes, ensuring the accuracy of the welding area of ​​the workpiece and the welding machine. Through the design of positioning and clamping functions, the workpiece can be fixed in the position of the slide, ensuring the stability of the workpiece during welding. Through the design of shock absorption function, the slide can be buffered as it rises and falls along the support direction, ensuring the stability of the workpiece during rising and falling.
