When dealing with workpieces of different sizes and shapes, frequent fixture changes are required, greatly increasing production preparation time and costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 In this embodiment of the utility model, a workpiece fixing and clamping structure includes an adjusting base assembly 1, on which a workpiece clamping mechanism 1 and a workpiece clamping mechanism 2 are fixedly installed respectively. The workpiece clamping mechanism 1 and workpiece clamping mechanism 2 are composed of the same structure; The workpiece clamping mechanism 2 includes a clamping drive seat 21, which is a rectangular slot with an opening on the right side. The clamping drive seat 21 has symmetrical placement slots 22 on the inner sides of its front and rear ends, and a dual-axis cylinder connecting seat 23 is symmetrically fixedly installed on the outer sides of its front and rear ends. A dual-axis cylinder 24 is fixedly installed on the inner side of each dual-axis cylinder connecting seat 23. The ends of the dual-axis cylinders 24 are placed in the placement slots 22, and a toothed plate pressure block 25 is fixedly installed on the ends of the dual-axis cylinders 24.

[0021] By adopting the above technical solution, the workpiece clamping mechanism 12 and the workpiece clamping mechanism 23 are co-directional adjustment structures. The drive cylinder 15 can adjust the two mechanisms at the same time. The dual-axis cylinder 24 drives the toothed plate pressure block 25 to adapt to workpieces of different widths, which can meet the clamping requirements of multiple specifications of workpieces and reduce the frequency of fixture replacement.

[0022] In this embodiment, the clamping drive seat 21 is fixedly installed on the upper surface of the mounting plate 111 on the right side. The mounting plate 111 is arranged symmetrically on the left and right sides, and the lower surface of the mounting plate 111 is symmetrically equipped with sliders 14 in the front and back. The workpiece clamping mechanism 23 is fixedly installed on the upper surface of the mounting plate 111 on the left side. The block 14, which is symmetrically arranged front and back, is slidably connected to the guide slide frame 13. The guide slide frame 13 is symmetrically fixedly installed on the upper surface of the inclined mounting plate 12. The inclined mounting plate 12 is fixedly installed on the front side of the upper end of the base frame 11. A drive cylinder 15 is fixedly installed on the right side of the upper surface of the inclined mounting plate 12 via a cylinder mounting bracket. The left end of the drive cylinder 15 is fixedly connected to the connecting seat 16. The upper end of the connecting seat 16 is fixedly connected to the transmission connecting block 17. A fixing plate 18 is fixedly installed on the right side of the upper end of the transmission connecting block 17.

[0023] By adopting the above technical solution, the clamping process is automatically driven by the drive cylinder 15 and the dual-axis cylinder 24, eliminating the need for manual operation, greatly improving production efficiency, and avoiding problems such as uneven clamping force and positioning deviation caused by manual operation.

[0024] In this embodiment, the fixing plate 18 is fixedly connected to the upper surface of the mounting plate 111 on the right side; the left side of the transmission connecting block 17 is fixedly connected to the transmission rod 19, the left end of the transmission rod 19 is fixedly connected to the fixing seat 110, and the upper end of the fixing seat 110 is connected to the lower end of the mounting plate 111 on the left side. Two clamping fixing seats 112 are fixedly installed on the upper surface of the inclined mounting plate 12, and clamping tooth plates 113 are fixedly installed on the left side of the upper end of each clamping fixing seat 112; the clamping fixing seat 112 and clamping tooth plate 113 on the right side are corresponding to the opening slot provided on the right side of the clamping drive seat 21; the clamping fixing seat 112 and clamping tooth plate 113 on the left side are corresponding to the opening slot provided on the right side of the clamping drive seat provided on the workpiece clamping mechanism 23.

[0025] By adopting the above technical solution, the toothed structure of the clamping toothed plate 113 increases the friction with the workpiece, and the dual-axis cylinder 24 clamps synchronously from both sides. With the stable transmission of the adjusting base assembly, the workpiece is accurately positioned and evenly stressed after clamping, effectively preventing workpiece deformation or displacement.

[0026] The working principle of this utility model is as follows: the inclined mounting plate 12 is mounted on the base frame 11, and the guide slide rod frame 13 is symmetrically fixed on the inclined mounting plate 12. The mounting plate 111 is slidably connected to the guide slide rod frame 13 through the slider 14. The drive cylinder 15 outputs power, which is transmitted to the transmission connecting block 17 through the connecting seat 16. The transmission connecting block 17 drives the right mounting plate 111 to slide along the guide slide rod frame 13 through the fixed plate 18 on the one hand, and drives the left mounting plate 111 to slide synchronously through the transmission rod 19 and the fixed seat 110 on the other hand, so as to realize the synchronous movement of the workpiece clamping mechanism 12 and the workpiece clamping mechanism 23, and adapt to workpieces of different lengths. Taking the workpiece clamping mechanism 2 as an example, the clamping drive seat 21 is fixedly mounted on the mounting plate 111, and the dual-axis cylinder 24 is mounted on the dual-axis cylinder connecting seat 23 at its front and rear ends. The toothed plate pressure block 25 at the end of the dual-axis cylinder 24 is placed in the placement groove 22. When the dual-axis cylinder 24 is activated, the toothed plate pressure block 25 moves inward and cooperates with the clamping toothed plate 113 on the clamping fixed seat 112 to clamp the workpiece from both sides. The toothed structure of the clamping toothed plate 113 enhances the friction and ensures the clamping stability. The workpiece clamping mechanism 12 and the workpiece clamping mechanism 23 are adjustable in the same direction. The drive cylinder 15 can adjust the two mechanisms at the same time. The dual-axis cylinder 24 drives the toothed plate pressure block 25 to adapt to workpieces of different widths, which can meet the clamping requirements of multiple specifications of workpieces and reduce the frequency of fixture replacement. The clamping process is automatically driven by the drive cylinder 15 and the dual-axis cylinder 24, eliminating the need for manual operation, which greatly improves production efficiency and avoids problems such as uneven clamping force and positioning deviation caused by manual operation. The toothed structure of the clamping toothed plate 113 increases the friction with the workpiece, and the dual-axis cylinder 24 clamps synchronously from both sides. Combined with the stable transmission of the adjusting base assembly, the workpiece is accurately positioned and evenly stressed after clamping, effectively preventing workpiece deformation or displacement.
