[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 6 As shown, an embodiment of the present utility model provides a novel mechanical clamp device, which specifically includes a processing platform 1, a fixed block 12 and two sets of clamping mechanisms. The fixed block 12 is fixedly connected to the lower end of the processing platform 1, and the lower end of the fixed block 12 is fixedly connected to the mounting base 6. Two sets of clamping mechanisms are provided at the lower part of the processing platform 1, and each set of clamping mechanisms specifically includes a third spur gear 13, a limiting groove 15, a limiting assembly and a transmission mechanism. The third spur gear 13 is provided on the upper side of the fixed block 12, and a rack 14 is slidably connected to the upper side of the fixed block 12. The rack 14 and the third spur gear 13 are meshed, and the upper end of the rack 14 is fixedly connected to the clamp 4. The limiting groove 15 is opened at the upper end of the fixed block 12, and the inner surface of the limiting groove 15 is slidably connected to the limiting block 16. The upper end of the limiting block 16 is fixedly connected to the lower end of the rack 14. The limiting assembly is arranged in the processing platform 1 and connected to the rack 14 to limit the sliding rack 14. The transmission mechanism is arranged in the mounting seat 6 and connected to the two third spur gears 13 to drive the two sets of clamping mechanisms to operate.

[0037] Specifically in this embodiment, the processing platform 1 is supported by the fixed block 12, and the internal components are protected by the fixed mounting seat 6. Since the first spur gear 10 is fixed to the output end of the motor 9, when the motor 9 is started, the first spur gear 10 is driven to rotate, and the two second spur gears 11 and the first spur gear 10 are meshed with each other. The four second spur gears 11 are meshed with each other in pairs, thereby driving the four second spur gears 11 to rotate according to the rotation of the first spur gear 10, completing the transmission of the two third spur gears 13. The two third spur gears 13 and the two racks 14 are meshed with each other, thereby driving the two racks 14 to slide on the surface of the fixed block 12. The inner surface of the limit groove 15 is convex, and when the rack 14 slides, it drives the limit block 16 to slide inside the limit groove 15, playing a role in limiting the sliding rack 14. The limit plate 18 slides inside the limit seat 17, and when the rack 14 slides, it drives the limit plate 18 to slide inside the limit seat 17, avoiding the rack 14 from tilting at an angle when sliding. Therefore, when the rack 14 slides, it drives the two clamps 4 to slide toward the middle under the action of force, completing the function of clamping and fixing the placed workpiece, strengthening the clamping force of the mechanical clamp on the workpiece, solving the problem of tilting during the process of position clamping and fixing, thereby improving the processing accuracy and quality of the workpiece and reducing the waste of time and resources.

[0038] It should be noted that the specific type of motor to be used is selected by relevant technicians familiar with this field, and the above-mentioned motor 9 and the like belong to the existing technology and will not be described in detail in this solution.

[0039] See also Figure 4 As shown, each set of limiting assemblies includes a limiting seat 17 and a limiting plate 18. The limiting seat 17 is fixedly connected to the upper end of the fixed block 12, and the limiting plate 18 is slidably connected to the inner surface of the limiting seat 17. One side end of the limiting plate 18 is fixedly connected to one side end of the rack 14. Specifically, in this embodiment, the limiting plate 18 slides inside the limiting seat 17. When the rack 14 slides, the limiting plate 18 is driven to slide inside the limiting seat 17, thereby limiting the sliding rack 14 and preventing the rack 14 from tilting during sliding.

[0040] See also Figure 2 As shown, the transmission mechanism specifically includes a motor 9, a first spur gear 10 and a rotating assembly. The motor 9 is fixedly connected to the lower end of the mounting base 6. The output end of the motor 9 moves through the lower end of the mounting base 6. The first spur gear 10 is fixedly connected to the output end of the motor 9. The lower end of the mounting base 6 is fixedly connected with a protective shell 5. The rotating assembly is arranged in the mounting base 6 and is connected to the two third spur gears 13 to drive the two third spur gears 13 to rotate.

[0041] Specifically in the present embodiment, by fixing the first spur gear 10 at the output end of the motor 9, when the motor 9 is started, the first spur gear 10 is driven to rotate, and at the same time, the two second spur gears 11 and the first spur gear 10 are meshed with each other, and the four second spur gears 11 are meshed with each other in pairs, thereby driving the four second spur gears 11 to rotate according to the rotation of the first spur gear 10, completing the function of transmitting the two third spur gears 13, thereby driving the two sets of clamping mechanisms to operate.

[0042] See also Figure 2 As shown, the rotating assembly specifically includes a plurality of second spur gears 11 (four second spur gears 11 are provided in this embodiment). Each of the second spur gears 11 is rotatably connected to the lower inner wall of the mounting base 6. The upper ends of the two second spur gears 11 are movable through the upper end of the fixing block 12. The lower ends of the two third spur gears 13 are respectively fixedly connected to the upper ends of two of the second spur gears 11. The two second spur gears 11 are meshed with each other with the first spur gear 10, and the four second spur gears 11 are meshed with each other in pairs. Therefore, the rotation of the first spur gear 10 drives the four second spur gears 11 to rotate, thereby completing the rotation of the two third spur gears 13.

[0043] See also Figure 1 and Figure 2 As shown, the lower end of the mounting seat 6 is threadedly connected to a plurality of bolts 8 (generally four, six or eight), and the outer surface of the mounting seat 6 is fixedly connected to a plurality of support blocks 7. The mounting seat 6 is installed on the lower end of the fixed block 12 by the four installed bolts 8. At the same time, the internal parts are protected according to the mounting seat 6, and the fixed support strength of the mounting seat 6 is strengthened according to the fixed multiple support blocks 7, thereby enhancing the stability of the device. The lower end of the processing platform 1 is fixedly connected to a plurality of support rods 2 (a total of four, one at each corner), and the adjacent ends of the multiple support rods 2 are respectively fixedly connected to a plurality of connecting blocks 3. The processing platform 1 is supported and fixed by the four fixed support rods 2. At the same time, the four support rods 2 are supported according to the fixed four connecting blocks 3 to prevent the device from shaking during operation.

[0044] The working principle and usage process of the utility model are as follows: first, the motor 9 is started to drive the first spur gear 10 to rotate. Since the two second spur gears 11 and the first spur gear 10 are meshed with each other, the four second spur gears 11 are driven to rotate according to the rotation of the first spur gear 10, and the two third spur gears 13 on the upper side are driven to rotate, and the two third spur gears 13 and the two racks 14 are respectively meshed with each other, thereby driving the two racks 14 to slide on the surface of the fixed block 12, and at the same time, under the action of force, the two limit blocks 16 and the two limit plates 18 are driven to slide on the inner surfaces of the two limit grooves 15 and the two limit seats 17 respectively, which plays a role in limiting the two sliding racks 14, and under the action of force, the two clamps 4 are driven to slide toward the middle respectively, completing the function of clamping and fixing the placed workpiece.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
