[0007] Furthermore, the top of the limiting column is dome-shaped, and the front and rear sides of the limiting column are arc-shaped.

[0008] Furthermore, the fixing seat is L-shaped, and the fixing seat is slidably connected to the clamping block.

[0009] Furthermore, the cross section of the clamping block is T-shaped, and the clamping block is slidably connected to the limiting block.

[0010] Furthermore, one side of the convex portion is V-shaped, and the other side of the convex portion is arc-shaped.

[0011] Furthermore, the upper end of the support is T-shaped, and a second proximity sensor is arranged at the front end of the support.

[0012] Furthermore, a lifting assembly is provided at the top front end of the base, and the lifting assembly includes a lifting cylinder, a lifting plate and a lifting rod.

[0013] Furthermore, the push rods are symmetrically distributed about the center of the lifting plate, and the center line of the lifting plate coincides with the center line of the support.

[0014] The utility model provides an automobile steering parts welding tool with auxiliary ejection, which has the following beneficial effects:

[0015] 1. The utility model provides a limit assembly. Since the limit column and the limit block just correspond to the hole position on the steering part of the automobile, the workpiece can be quickly positioned when it is placed to prevent it from being skewed. At the same time, the top of the limit column is dome-shaped, which can guide the workpiece, which is beneficial to improving the efficiency of workpiece insertion. After another workpiece is placed on the top of the limit block, the spring seat will push the clamping block under the limit of the fixed seat, so that the groove of the other workpiece just fits with the V-shaped side of the convex part, thereby quickly limiting the workpiece and preventing the workpiece from being skewed. After that, the clamping cylinder drives the clamping plate to move downward to press the two workpieces together, so that the welding robot can be used to weld the workpieces later.

[0016] 2. The utility model is provided with a ejector assembly. After welding, when the workpiece needs to be taken out, after the clamping cylinder drives the clamping plate to separate from the workpiece, the ejector cylinder can be controlled to drive the lifting plate to move up, so that the ejector rods on both sides simultaneously drive the workpiece to move up smoothly, so that it is separated from the limit column and the limit block, avoiding the manual removal process. Due to the uneven force on both sides of the workpiece, it causes skewness and increases the difficulty of unloading, thereby improving the efficiency of unloading. BRIEF DESCRIPTION OF THE DRAWINGS

A clamping cylinder 2 is provided above the rear end of the base 1, and a clamping plate 3 is connected to the top of the clamping cylinder 2. The clamping cylinder 2 drives the clamping plate 3 to move downward to press the two workpieces together. A first proximity sensor 4 is provided at one end of the clamping plate 3. The limit assembly 5 is provided at the top center of the base 1. The limit assembly 5 includes a support 501, a limit column 502, a limit block 503, and a fixing seat 504. , spring seat 505, clamping block 506 and convex portion 507, the top ends of the support 501 are provided with limiting posts 502, and the top center of the support 501 is fixed with a limiting block 503. Since the limiting posts 502 and the limiting block 503 just correspond to the holes on the steering part of the car, the workpiece can be quickly positioned when it is placed to prevent it from being deflected. The top of the limiting post 502 is dome-shaped, and the front and rear sides of the limiting post 502 are arc-shaped. The top of the limiting post 502 is dome-shaped. The shape can guide the workpiece, which is beneficial to improving the efficiency of workpiece insertion. A fixed seat 504 is placed in the center of the top of the limit block 503, and the interior of the fixed seat 504 is connected to a spring seat 505, and one end of the spring seat 505 is provided with a clamping block 506. The fixed seat 504 is L-shaped, and the fixed seat 504 is slidably connected to the clamping block 506. The fixed seat 504 can limit the clamping block 506. The cross-section of the clamping block 506 is T-shaped, and the clamping block 506 is connected to the limit block 503. Sliding connection, the groove on the limit block 503 can guide the clamping block 506, and a protrusion 507 is provided on the top of one end of the limit block 503. One side of the protrusion 507 is V-shaped, and the other side of the protrusion 507 is arc-shaped. After placing another workpiece on the top of the limit block 503, the spring seat 505 will push the clamping block 506 under the limit of the fixed seat 504, so that the groove of the other workpiece just fits with the V-shaped side of the protrusion 507, thereby quickly limiting the workpiece.

[0023] like Figure 2 and Figure 3As shown, the upper end of the support 501 is T-shaped, and a second proximity sensor 6 is installed at the front end of the support 501. The second proximity sensor 6 can detect whether the workpiece is placed in place. A lifting assembly 7 is provided at the top front end of the base 1. The lifting assembly 7 includes a lifting cylinder 701, a lifting plate 702 and a lifting rod 703. The top of the lifting cylinder 701 is connected to the lifting plate 702, and the top two ends of the lifting plate 702 are installed with lifting rods 703. The lifting rods 703 are symmetrically distributed about the center of the lifting plate 702, and the center line of the lifting plate 702 coincides with the center line of the support 501. After the clamping cylinder 2 drives the clamping plate 3 to separate from the workpiece, it can control the lifting cylinder 701 to drive the lifting plate 702 to move up, so that the lifting rods 703 on both sides simultaneously drive the workpiece to move up smoothly, so that it is separated from the limit column 502 and the limit block 503, avoiding the manual process of taking out the workpiece.

After that, the workpiece will contact the second proximity sensor 6 (model IFW200), so that the second proximity sensor 6 detects that the workpiece is in place. Next, after another workpiece is placed on top of the limiting block 503, the spring seat 505 will push the clamping block 506 under the limit of the fixed seat 504, so that the groove of the other workpiece is just aligned with the V-shaped side of the protrusion 507. After the workpieces are fitted together, the workpieces can be quickly limited. Then, the clamping cylinder 2 drives the clamping plate 3 to move downward to press the two workpieces together. At this time, the first proximity sensor 4 can detect the workpiece, which indicates that the positioning is completed, thereby facilitating the subsequent use of a welding robot to weld the workpieces. Finally, after welding, when the clamping cylinder 2 is controlled to drive the clamping plate 3 to separate from the workpiece, the ejection cylinder 701 is controlled to drive the lifting plate 702 to move upward, so that the ejector rods 703 on both sides simultaneously drive the workpiece to move upward smoothly, separating it from the limiting column 502 and the limiting block 503, thereby improving the efficiency of unloading.
