[0034] In one aspect of this embodiment, Figure 7-10As shown, the fastening mechanism includes a first groove 7 which is opened in the clamping seat 3 and is connected to the thread groove. The clamping bolt 1 moves downward and passes through the first groove 7. An extrusion plate 8 is slidably connected in the first groove 7. The bottom end of the extrusion plate 8 is fixedly connected to a first connecting rod 10. A first hydraulic oil channel 6 is opened in the clamping seat 3. The first connecting rod 10 moves downward and passes through the first hydraulic oil channel 6. The bottom end of the first connecting rod 10 is fixedly connected to a first piston plate 11. The bottom end of the extrusion plate 8 is fixedly connected to a positioning spring 9. The positioning spring 9 is fixedly connected to the first groove 7. The positioning spring 9 is sleeved on the circumferential surface of the first connecting rod 10.

The two supporting plates 191 are respectively provided with two second positioning grooves 33 and two first positioning grooves 51. The two rod parts 42 are respectively provided on the upper sides of the two supporting plates 191; when the clamping bolt 1 is screwed to fix the upper pressure block 2, the clamping bolt 1 is threaded downward into the thread groove. When the bottom end of the clamping bolt 1 gradually drops into the first groove 7 as it is screwed, the squeezing plate 8 is squeezed downward to squeeze the positioning spring 9, and at the same time, the first piston plate 11 is driven by the first connecting rod 10 to slide in the first hydraulic oil channel 6 to squeeze. The hydraulic oil in the first hydraulic oil channel 6 is pressed, and the hydraulic oil in the first hydraulic oil channel 6 is squeezed and moved into the two second hydraulic oil channels 12 on both sides, respectively squeezing the two second piston plates 13 located in the two second hydraulic oil channels 12, and the two second piston plates 13 move upward, and the two second piston plates 13 respectively drive the two first connecting plates 16 to move upward through the two sliding rods 15, and the two first connecting plates 16 drive the two second connecting plates 18 to move upward, and the two second connecting plates 18 drive the two supporting plates 191 upward through the two second connecting rods 19 to squeeze the bottom end of the rod component 42 so that it fits tightly with the block component 41.

[0037] Example 2

[0038] Improvements based on Example 1: Refer to the attached Figures 1-6 A mold frame welding tool includes a clamping seat 3, an upper clamping block 2 arranged above the clamping seat 3, and a front end clamping block 5 cooperating with the clamping seat 3. The upper clamping block 2 and the clamping seat 3 are connected by a clamping bolt 1. The front end clamping block 5 and the clamping seat 3 are respectively provided with a first positioning hole 52 and a second positioning hole 31 that match each other; the clamping seat 3 is also provided with a positioning block 32 and a second positioning groove 33 located on both sides of the positioning block 32.

[0039] A first positioning groove 51 is provided on the side of the front end pressure block 5 that cooperates with the pressing seat 3. The first positioning groove 51 corresponds to the position of the second positioning groove 33. That is, when the front end pressure block 5 cooperates with the pressing seat 3, the first positioning groove 51 and the second positioning groove 33 combine to form a through groove for accommodating the rod component 42 to be processed.

[0040] The cross section of the first positioning groove 51 is V-shaped. The first positioning groove 51 is a V-shaped groove used to position the verticality of the rod component 42 and the block component 41.

[0041] The positioning block 32 and the second positioning groove 33 are located on the same plane, and the positioning block 32 is perpendicular to the upper end of the pressing seat 3 and is integrally connected to the pressing seat 3. The end face of the rod component 42 and the lower end face of the block component 41 must be highly perpendicular and have high dimensional accuracy. After welding, the rod surface is not disassembled and must be milled flat using a machining center.

[0042] The upper pressing block 2 is provided with a through hole 22 for the compression bolt 1 to pass through, and the through hole 22 is capsule-shaped or gourd-shaped. Through this through hole shape setting, the lateral position of the upper pressing block 2 can be controlled by adjusting the position where the compression bolt 1 passes through.

[0043] A clamping arm 21 is provided on one side of the upper clamp 2 near the clamping seat 3. The clamping arm 21 is integrally connected to the upper clamp 2. The clamping arm 21 ensures a minimum clamping distance between the upper clamp 2 and the clamping seat 3, preventing the upper clamp 2 and the clamping seat 3 from getting too close and becoming stuck. It also facilitates adjustment of the position of the upper clamp 2.

[0044] Example 3

[0045] Improvements based on Example 1: Refer to the attached Figures 1-6 The workpiece 4 includes a block component 41 arranged between the upper pressure block 2 and the clamping seat 3, and a rod component 42 limited between the clamping seat 3 and the front end pressure block 5. Two welding holes 401 are provided on the block component 41, and the distance between the two welding holes 401 is greater than the width of the positioning block 32, so that the welding holes 401 are exposed when the workpiece is clamped for easy welding.

[0046] Working principle: when the clamping bolt 1 is screwed to fix the upper pressure block 2, the clamping bolt 1 is threaded downward into the thread groove. When the bottom end of the clamping bolt 1 gradually drops into the first groove 7 as it is screwed, it squeezes the squeezing plate 8. The squeezing plate 8 is squeezed downward to squeeze the positioning spring 9. At the same time, the first connecting rod 10 drives the first piston plate 11 to slide in the first hydraulic oil channel 6 to squeeze the hydraulic oil in the first hydraulic oil channel 6. The hydraulic oil in the first hydraulic oil channel 6 is squeezed and moves to the two second hydraulic oil channels 12 on both sides, respectively squeezing the two second piston plates 13 located in the two second hydraulic oil channels 12, and the two second piston plates 13 move upward. The two second connecting plates 18 drive the two second connecting plates 18 to move upward, and the two second connecting plates 18 drive the two supporting plates 191 to squeeze the bottom end of the rod component 42 upward through the two second connecting rods 19, so that it fits tightly with the block component 41. At the same time, the strong spring 17 arranged between the first connecting plate 16 and the second connecting plate 18 can provide a buffer for the movement of the second connecting plate 18. When the supporting plate 191 squeezes the stationary rod component 42, the extrusion force of the first connecting plate 16 will compress the strong spring 17 to provide a buffer.
