[0002] Sulfurization is a process involving the introduction of sulfur or sulfur-containing compounds into the surface or interior of a workpiece. Sulfurization is a chemical heat treatment process that involves a chemical reaction between the workpiece and sulfur or sulfur-containing compounds under specific conditions, thereby forming a sulfide infiltration layer on or inside the workpiece. This infiltration layer can alter the physical and chemical properties of the workpiece surface, improving its wear resistance, corrosion resistance, and anti-galling ability.

[0003] After vulcanization, the flash of the sliding cover of the engine motor is usually handled manually by a single worker. However, based on the current production volume and processing speed, it requires three workers to work together, which is labor-intensive, inefficient, and the processing is unstable, sometimes resulting in product damage.

[0004] Therefore, a clamping device is proposed for deburring vulcanized workpieces before the deburring process. Utility Model Content

[0026] like Figures 1 to 6 As shown, a specific embodiment of this utility model provides a clamping device for vulcanized workpieces before deflashing, including a base plate 1, a limiting rod 2 fixedly connected to the base plate 1, a mold core strip 3 provided on the limiting rod 2, and a plurality of workpieces 4 provided on the mold core strip 3, with ten workpieces 4 arranged on the mold core strip 3. After vulcanization on the mold core strip 3, there are spaces between the workpieces 4 as follows: Figure 2 The flash shown is provided at the top of the base plate 1 for processing the flash on the workpiece 4. By setting the clamping component, the vulcanized workpiece 4 can be clamped, so that the flash can be separated from the workpiece 4 after clamping, thereby replacing manual operation, improving efficiency, and reducing damage caused by manual operation. The clamping component includes a connecting plate 5 and a moving plate 6 at the top of the base plate 1. An upper jig 7 and a lower jig 8 are provided between the connecting plate 5 and the moving plate 6 for clamping the flash on the workpiece 4. Both the upper jig 7 and the lower jig 8 are provided with serrated patterns 9 that are adapted to the workpiece 4.

[0027] like Figures 1 to 6 As shown, specifically, when processing the flash between the vulcanized workpieces 4, the mold core strip 3 is placed at the top of the limiting rod 2. The mold core strip 3 has positioning holes 10 that match the limiting rod 2. Two long slots 11 are opened on the base plate 1, and the moving plate 6 is slidably connected in the long slots 11. Positioning and docking are completed by inserting the limiting rod 2 into the positioning holes 10. A moving block 12 is slidably connected in the long slots 11, and a long plate 13 is fixedly connected between the moving block 12 and the moving plate 6. The long plate 13 is fixed with... The device is connected to an electric push rod 14, which can be activated to push the long plate 13 so that the moving block 12 and the moving plate 6 can move in the long groove 11. This causes the upper fixture 7 and the lower fixture 8 between the connecting plates 5 and the moving plate 6 on both sides to move. The components on both sides move away from each other, increasing the distance between the two sets of upper fixtures 7 and lower fixtures 8. This makes it easier to place the mold core strip 3 on the top of the limiting rod 2 and to remove the mold core strip 3 after clamping and removing the flash.

[0028] like Figures 1 to 6As shown, specifically, after the mold core strip 3 is placed in a limiting groove 15, the connecting plate 5 has a limiting groove 15, and the upper mold fixture 7 and the lower mold fixture 8 are slidably connected in the limiting groove 15. A motor 16 is fixedly installed on the connecting plate 5, and a threaded rod 17 is fixedly connected to the output shaft of the motor 16. The threaded rod 17 is threadedly connected to the upper mold fixture 7 and the lower mold fixture 8. When the motor 16 is started, it drives the threaded rod 17 to rotate, so that the upper mold fixture 7 and the lower mold fixture 8 move closer to each other in the limiting groove 15 and gradually approach the workpiece 4 on the mold core strip 3. The threaded rod 17 is selected as a bidirectional threaded rod, so as to achieve the purpose of the upper mold fixture 7 and the lower mold fixture 8 moving closer or further away from each other. When the upper mold fixture 7 and the lower mold fixture 8 move closer to each other and approach the workpiece 4, the workpiece 4 gradually passes through the serrated pattern 9 on the upper mold fixture 7 and the lower mold fixture 8. Then the upper mold fixture 7 and the lower mold fixture 8 move towards the workpiece 4. The flash between the workpiece 4 is clamped. A cylinder 21 is fixedly installed on the moving plate 6. A support plate 22 is fixedly connected to the output shaft of the cylinder 21. A connecting rod 23 is slidably connected to the support plate 22. A pressure plate 24 is fixedly connected to the connecting rod 23. A second spring 25 is fixedly connected between the pressure plate 24 and the support plate 22. After the upper jig 7 and the lower jig 8 clamp the flash between the workpiece 4, the cylinder 21 is activated to extend its output shaft downward, thereby driving the support plate 22 and the pressure plate 24 to move downward and make the pressure plate 24 fit against the mold core strip 3. As the output shaft of the cylinder 21 continues to move downward, the connecting rod 23 slides in the support plate 22. The second spring 25 between the support plate 22 and the pressure plate 24 is compressed by force to generate a reaction force. Under its reaction force, pressure is applied to the pressure plate 24 to squeeze the mold core strip 3, thereby making the mold core strip 3 stable on the limit rod 2.

[0029] like Figures 1 to 6As shown, specifically, during the continuous downward extension of the output shaft of the aforementioned cylinder 21, its output shaft pushes the upper molded fixture 7 at its bottom end, thereby causing the upper molded fixture 7, the lower molded fixture 8, and the connecting plate 5 to move downward as a whole. A guide groove 18 is provided in the moving plate 6, and both the upper molded fixture 7 and the lower molded fixture 8 are slidably connected in the guide groove 18. A stop block 19 is slidably connected in the guide groove 18. A first spring 20 is fixedly connected between the stop block 19 and the moving plate 6, and between the connecting plate 5 and the moving block 12. During the downward movement, the upper molded fixture 7 and the lower molded fixture 8 move downward in the guide groove 18, and the connecting plate 5 moves downward accordingly. At this time, the first spring 20 is compressed and generates a reaction force, while the upper molded fixture 7 and the lower molded fixture 8... As it gradually moves downward, it creates a tearing effect on the burrs clamped between the two parts, thereby separating the burrs from the workpiece 4 and removing the burrs between the workpiece 4. After the burrs are removed, the drive cylinder 21 moves its output shaft upward to retract and reset. The reaction force between the second springs 25 is lost, and the pressure plate 24 also gradually moves upward to reset, no longer squeezing and fixing the mold core strip 3. After the output shaft of the cylinder 21 disengages from the upper mold fixture 7, under the reaction force of the first spring 20, the upper mold fixture 7, the lower mold fixture 8, and the connecting plate 5 move upward to reset as a whole. Then, the long plate 13 can be pushed by the aforementioned start electric push rod 14 to remove the mold core strip 3, that is, to remove the workpiece 4 after the burrs have been removed.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
