[0019] Detailed Implementation
[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0021] like Figure 1 and Figure 2As shown, this utility model discloses a slanted push clamping mechanism, including a connecting drive rivet 1, a pulling rod 2, a sliding rod 3, and a base 5. A driving device is fixedly connected to the bottom of the connecting drive rivet 1, and a T-shaped piece is fixedly installed on the top of the connecting drive rivet 1. The pulling rod 2 and the sliding rod 3 are installed in a right-angle combination. The pulling rod 2 is a top-slanted column with a 15° slant on its upper surface. A concave dovetail groove is formed in the middle of the slant of the pulling rod 2. The sliding rod 3 is a left-end slanted column with a 15° slant on its left surface. A trapezoidal tenon is fixedly installed in the middle of the left slant of the sliding rod 3. The trapezoidal tenon precisely engages with the concave dovetail groove to slide, thereby preventing radial displacement during driving. The pull rod 2 has a T-shaped hole at its bottom, which is opened for axial movement. The T-shaped part slides into the T-shaped hole to connect the drive pin 1 to the pull rod 2. The base 5 serves as a fixed base and has a process hole on it to facilitate the installation of the pull rod 2 and the sliding rod 3. A cylindrical process hole is opened in the middle of the base 5, and the pull rod 2 is intermittently set in the cylindrical process hole and slides freely in the cylindrical process hole. An installation process hole is opened in the middle of the right end of the base 5 and is connected to the cylindrical process hole. The sliding rod 3 is intermittently set in the installation process hole and slides freely in the installation process hole.
[0022] A receiving groove is provided at the bottom of the base 5, which is connected to a cylindrical process hole. The receiving groove is used to provide a movable cavity for connecting the drive rivet 1 during the assembly process with the pull rod 2.
[0023] A dust cover 6 is installed on the top of the base 5. The dust cover 6 is used to close the cylindrical process hole for mounting the base 5 and also serves as a grease injection window. Injecting grease improves service life and reduces fit error.
[0024] A V-shaped push block 4 is provided on the right side of the sliding push rod 3. A circular groove is opened on the left end face of the V-shaped push block 4. The circular groove is engaged with the sliding push rod 3. The V-shaped push block 4 and the sliding push rod 3 are connected by fixing bolts. The V-shaped push block 4 is in contact with the product being processed and plays the role of clamping the parts.
[0025] Working principle
[0026] In use, the product to be processed is placed on the right side of the device. Through hydraulic drive of an external drive device, the pull rod 2, which is engaged with the drive pin 1, slides within the cylindrical process hole. The concave dovetail groove and trapezoidal tenon slide in tandem, causing the sliding rod 3 to slide to the right within the installation process hole. This effectively prevents radial movement of the V-shaped push block 4, greatly enhancing the stability of the processed product installation and resulting in more regular shapes of the processed parts. Simultaneously, the right-angled top of the V-shaped push block 4 axially limits the radial end of the processed product, preventing it from tilting during clamping. This significantly enhances the stability of the parts processing, making it widely applicable in machining center fixtures and automated fixtures.
