[0036] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, the fixture for processing automobile parts provided by the present invention includes:

[0038] Base 1, fixed end assembly 2, electric slide rail 3, sliding seat 4, rotating rod 5, fixed frame 6, first bidirectional screw 7, moving block 8 and first clamping block 9;

[0039] A fixed end assembly 2 is provided on one side of the surface of the base 1, and an electric slide rail 3 is provided on the other side of the surface of the base 1. The electric slide rail 3 is arranged perpendicular to the fixed end assembly 2. A sliding seat 4 is slidably connected to the electric slide rail 3, and the sliding seat 4 is connected to a rotating rod 5. The rotating rod 5 and the sliding seat 4 are movably connected. A fixed frame 6 is fixedly connected to the end of the rotating rod 5 facing the fixed end assembly 2, and a first bidirectional screw 7 is connected to the center of the fixed frame 6. Both sides of the first bidirectional screw 7 are threadedly connected to moving blocks 8. The opposite surfaces of the two moving blocks 8 are fixedly connected to the first clamping block 9 for clamping automobile parts.

[0040] Specifically, the base 1, which is table-shaped and serves as the basic support component, has a fixed end assembly 2 fixed to one side of its surface, serving as a fixture for automotive parts. On the other side, an electric slide 3 is mounted perpendicular to the fixed end assembly 2. A sliding seat 4 is slidably connected to the electric slide 3, serving as a slider on the electric slide 3. This allows the sliding seat 4 to reciprocate in a straight line under the drive of the electric slide 3. A rotating rod 5 comprises a rectangular portion and rod-shaped portions integrally formed on either side of the rectangular portion. The rod-shaped portions are inserted into the top of the sliding seat 4 and secured with four locking nuts, creating a flexible connection between the sliding seat 4 and the rotating rod 5. This allows manual rotation of the rotating rod 5 about a horizontal axis, typically with an angle of 15° to 45° (the angle can be manually adjusted depending on the location of the automotive part to be welded). The end of the rotating rod 5 facing the fixed end assembly 2 is rigidly connected to a fixed frame 6. A first bidirectional screw 7 is positioned at the center of the fixed frame 6, with threads of opposite rotation on its left and right sides. The two moving blocks 8 are respectively engaged with the threads on both sides of the first bidirectional screw 7, and the two moving blocks 8 move toward or away from each other along the axial direction of the first bidirectional screw 7. The first clamping block 9 is fixedly mounted on the opposite side of the two moving blocks 8, forming a working area for clamping automobile parts.

[0041] The electric slide rail 3 drives the sliding seat 4 to move, adjusting the spacing between the fixed frame 6 and the fixed end assembly 2 to accommodate automotive parts of varying sizes. The movable connection between the rotating rod 5 and the sliding seat 4 allows the rotating rod 5 to rotate about its axis, achieving multi-angle positioning of parts and a wide range of applications. The rotation of the first bidirectional screw 7 drives the two first clamping blocks 9 to move synchronously and in close proximity, achieving stable clamping of parts. The synergistic effect of these three factors makes the fixture of this utility model have the effects of adjustable length, controllable angle, and balanced clamping force, which can meet the diverse positioning and fixing requirements of automotive parts during the processing process, improving versatility and applicability.

[0042] In an embodiment of the present invention, the sliding seat 4 includes a support seat 401 and a bracket 402; a sliding groove is opened in the middle of the support seat 401 along the outer contour of the electric slide rail 3, two brackets 402 are arranged in parallel at the top of the support seat 401, and a rotating rod 5 is arranged between the two brackets 402.

[0043] The rotating rod 5 is inserted between the two brackets 402 , and locking nuts are provided at both ends of the rotating rod 5 .

[0044] The fixing frame 6 is U-shaped, the closed end of the fixing frame 6 is fixedly connected to the rotating rod 5, and the center of the open end of the fixing frame 6 is plugged into the first bidirectional screw 7.

[0045] Specifically, a sliding groove is machined in the middle of the support seat 401 along the outer contour of the electric slide rail 3, and the sliding groove forms a surface contact with the slider of the electric slide rail 3 to ensure that the support seat 401 can slide linearly along the axial direction of the electric slide rail 3. Two parallel brackets 402 are vertically welded to the surface of the support seat 401, and coaxial circular through holes are provided on the opposite surfaces of the brackets 402 for passing the rotating rod 5. External threads are turned on both ends of the rotating rod 5, and axial positioning is achieved by tightening the locking nut, so that the rotating rod 5 can be manually rotated around its own axis between the brackets 402. The fixed frame 6 is U-shaped, and its closed end (the bottom of the U-shape) is connected to the end of the rotating rod 5 by welding or bolts, so that the two rotate synchronously. A coaxial bearing hole is provided at the center of the open end (the two side arms of the U-shape), and the first bidirectional screw 7 is inserted into the open end of the fixed frame 6.

[0046] The support base 401 and the motorized slide 3 cooperate to provide linear movement along the X-axis, allowing the fixture to accommodate workpieces of varying lengths. The rotating rod 5 and bracket 402 rotate about the Y-axis, enabling multi-angle positioning of the workpiece. The moving block 8, driven by the first bidirectional screw 7, provides clamping along the Z-axis, ensuring stable workpiece fixation. This system meets the adaptability requirements for workpieces of varying sizes and shapes during automotive parts processing. For example, to adjust the clamping angle, simply loosen the locking nuts at each end of the rotating rod 5, rotate it to the desired position, and then retighten.

[0047] In the embodiment of the present utility model, the fixed end assembly 2 includes a protective shell 201, a second bidirectional threaded rod 202, a sliding block 203 and a second clamping block 204;

[0048] The protective shell 201 is fixed on the surface of the base 1 , and a second bidirectional threaded rod 202 is set inside the protective shell 201 . Both sides of the second bidirectional threaded rod 202 are threadedly connected with sliding blocks 203 , and second clamping blocks 204 are set on the opposite surfaces of the two sliding blocks 203 .

[0049] The protective shell 201 is in a rectangular hollow shape and is used to block welding slag; strip-shaped holes are opened on both sides of the protective shell 201.

[0050] The sliding block 203 includes a sliding portion 205 and a connecting portion 206 . The sliding portion 205 slides along the strip hole through the second bidirectional threaded rod 202 . The top of the sliding portion 205 is integrally formed with the connecting portion 206 . The connecting portion 206 is fixedly connected to the second clamping block 204 .

[0051] Specifically, the protective shell 201 of the fixed end assembly 2 is fixed vertically to the surface of the base 1, and the interior is hollow to form a rectangular cavity for accommodating the second bidirectional threaded rod 202. The left and right sides of the second bidirectional threaded rod 202 are respectively processed with thread segments of opposite rotation directions. The sliding parts 205 of the two sliding blocks 203 are in the shape of a square, respectively engaged with the two side threads of the second bidirectional threaded rod 202, and embedded in the bar holes opened on both sides of the protective shell 201. The width of the bar hole matches the thickness of the sliding part 205 to form a sliding guide pair, ensuring that the sliding block 203 can move linearly along the bar hole. The top of the sliding part 205 is integrally cast with the connecting part 206, and the end face of the connecting part 206 is welded to the second clamping block 204. When the second bidirectional threaded rod 202 is rotated, the sliding blocks 203 on both sides will move toward or away from each other synchronously, driving the second clamping block 204 to achieve clamping or loosening.

[0052] The protective shell 201 serves as both a supporting structure for the second bidirectional threaded rod 202 and a welding protective device; the cooperation between the strip hole and the sliding part 205 constrains the movement trajectory of the sliding block 203, preventing welding slag from entering the interior of the second bidirectional threaded rod 202; through the coordinated action of the second clamping block 204 and the first clamping block 9, the two ends of the workpiece are clamped synchronously, and the protective shell 201 is used to protect the second bidirectional threaded rod 202 area, reducing welding slag erosion and improving the reliability and service life of the tooling fixture.

[0053] In the embodiment of the present utility model, either side of the first bidirectional screw 7 extends out of the fixed frame 6 and is fixedly connected to the first hand wheel 10;

[0054] Either side of the second bidirectional threaded rod 202 extends out of the protective shell 201 and is fixedly connected to the second hand wheel 11 .

[0055] The opposite sides of the two first clamping blocks 9 and the opposite sides of the two second clamping blocks 204 are both provided with an anti-wear layer.

[0056] The anti-wear layer is rubber or welded high chromium cast iron.

[0057] Specifically, the right (or left) end of the first bidirectional screw 7 extends beyond the outer wall of the fixed frame 6 and is secured to the first handwheel 10. Manual rotation of the first handwheel 10 synchronously drives the first bidirectional screw 7. The right (or left) end of the second bidirectional threaded rod 202 similarly extends beyond the outer wall of the protective housing 201 and is secured to the second handwheel 11 in the same manner. The opposing surfaces of the two first clamping blocks 9 (i.e., the clamping surfaces that contact the workpiece) and the opposing surfaces of the two second clamping blocks 204 are both coated with a wear-resistant layer through bonding or hardfacing to prevent scratches on the workpiece surface.

[0058] Based on the above embodiment, the specific working process of the fixture for processing automobile parts provided by the utility model is as follows:

[0059] Place one of the automotive parts to be welded between the two second clamping blocks 204 of the fixed end assembly 2. Turn the second handwheel 11 to rotate the second bidirectional threaded rod 202, causing the sliding block 203 to move the second clamping blocks 204 toward each other to complete the clamping. Place the other part between the two first clamping blocks 9 of the fixed frame 6. Turn the first handwheel 10 to clamp the part via the first bidirectional threaded rod 7. Activate the electric slide 3 to drive the sliding seat 4 to move the two parts closer together. Loosen the locking nuts at both ends of the rotating rod 5. Manually rotate the rotating rod 5 to drive the fixed frame 6 to adjust the angle of the part to ensure the welding points are aligned. After adjustment, tighten the locking nuts to fix the angle. After confirming that the position and angle of the two parts are correct, proceed with the welding operation.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
