Description

Technical Field

[0001] This utility model belongs to the field of stamping processing technology, specifically relating to a stamping clamping device. Background Technology

[0028] The elastic clamping frame 9 comprises a lower horizontal plate 901, a second U-shaped plate 902, an upper horizontal plate 903, a clamping plate 904, a first hollow block 905, a spring 906 and a second hollow block 907, the bottom of the lower horizontal plate 901 is attached to the upper surface of the workbench 1, the upper surface of the lower horizontal plate 901 is fixedly connected with the bottom of the second U-shaped plate 902, the bottom of the lower horizontal plate 901 is fixedly connected with the upper surface of the first U-shaped plate 5, the inner wall of the second U-shaped plate 902 and the upper surface of the lower horizontal plate 901 are attached to the surface of the upper horizontal plate 903, the upper surface of the second U-shaped plate 902 is fixedly connected with the bottom of the first hollow block 905, the inner wall of the first hollow block 905 and the inner wall of the second hollow block 907 are fixedly connected with the surface of the spring 906, the side surface of the upper horizontal plate 903 is fixedly connected with the side surface of the clamping plate 904, the upper surface of the lower horizontal plate 901 is fixedly connected with the bottom of the fixing mechanism 10, and the upper surface of the upper horizontal plate 903 is attached to the bottom of the fixing mechanism 10.

[0029] The fixing mechanism 10 comprises a stand 1001, a mounting plate 1002, a second hydraulic push rod 1003, a third connecting block 1004 and a rubber pad 1005, the bottom of the stand 1001 is fixedly connected with the upper surface of the lower horizontal plate 901, the upper surface of the stand 1001 is fixedly connected with the bottom of the mounting plate 1002, the bottom of the mounting plate 1002 is fixedly connected with the upper surface of the second hydraulic push rod 1003, the bottom of the second hydraulic push rod 1003 is fixedly connected with the upper surface of the third connecting block 1004, the bottom of the third connecting block 1004 is bonded with the bottom of the rubber pad 1005, and the bottom of the rubber pad 1005 is attached to the upper surface of the upper horizontal plate 903.

[0030] It should be noted that the cooperation of the guide plate 4, the first U-shaped plate 5 and the first connecting block 6 enables the elastic clamping frame 9 to move leftward and rightward only, and the first hydraulic push rod 8 is used to control the leftward and rightward movement of the elastic clamping frame 9, the cooperation of the lower horizontal plate 901 and the second U-shaped plate 902 enables the upper horizontal plate 903 to move leftward and rightward only, when the elastic clamping frame 9 moves to the side close to the stamping part, the clamping plate 904 first contacts the stamping part, and the spring 906 pulls the second hollow block 907 to make the clamping plate 904 closely contact the stamping part, at the same time, as the lower horizontal plate 901 continues to move, the distance between the clamping plate 904 and the lower horizontal plate 901 can be automatically adjusted according to the profile of the stamping part, the second hydraulic push rod 1003 is used to control the upward and downward movement of the rubber pad 1005, when the rubber pad 1005 presses the upper horizontal plate 903, the friction between the rubber pad 1005 and the upper horizontal plate 903 makes the upper horizontal plate 903 unable to move, and the distance between the clamping plate 904 and the lower horizontal plate 901 cannot be changed, and after the rubber pad 1005 is separated from the upper horizontal plate 903, the upper horizontal plate 903 can move leftward and rightward on the lower horizontal plate 901.

[0031] AsFigures 1 to 8 As shown, the inside of the guide plate 4 is provided with a second strip hole 11, and the bottom of the guide plate 4 and the left and right sides of the second connecting block 7 are fixedly connected with a driving mechanism 12, and the surface of the driving mechanism 12 is bonded with a rubber sleeve 13, and the rubber sleeve 13 is located in the second strip hole 11.

[0032] The driving mechanism 12 comprises a motor support 1201, a stepping motor 1202, a rotating shaft 1203, a bearing 1204 and a fourth connecting block 1205, the left and right sides of the second connecting block 7 are fixedly connected with the side surface of the motor support 1201, the side surface of the motor support 1201 is fixedly connected with the side surface of the stepping motor 1202, the output end of the stepping motor 1202 is fixedly connected with one end of the rotating shaft 1203, the surface of the rotating shaft 1203 is fixedly connected with the inner ring of the bearing 1204, the outer ring of the bearing 1204 is fixedly connected with the inner wall of the fourth connecting block 1205, and the upper surface of the fourth connecting block 1205 is fixedly connected with the bottom of the guide plate 4.

[0033] It should be noted that the stepping motor 1202 can drive the rubber sleeve 13 to rotate, and when the stamping part is placed on the workbench 1, the rubber sleeve 13 is in contact with the stamping part, and the friction between the rubber sleeve 13 and the stamping part can drive the rubber sleeve 13 to move forward or backward when rotating, so that the stamping part on the workbench 1 can be automatically moved through the cooperation of the driving mechanism 12 and the rubber sleeve 13, thereby facilitating the user to adjust the position of the stamping part on the workbench 1, and the third U-shaped plate 14 can support the rubber sleeve 13.

[0034] The working principle of the utility model is that: first, the second hydraulic push rod 1003 is used to separate the rubber pad 1005 from the upper horizontal plate 903, then the stamping part is placed on the workbench 1, and the rubber sleeve 13 is in contact with the stamping part, when it is necessary to adjust the position of the stamping part, the stepping motor 1202 is used to control the rubber sleeve 13 to rotate, and the friction between the rubber sleeve 13 and the stamping part can drive the rubber sleeve 13 to move forward or backward when rotating.

[0035] When the stamping part is located at a suitable position, the first hydraulic push rod 8 is used to move the elastic clamping frame 9 to the side close to the stamping part, at this time, the clamping plate 904 is first in contact with the stamping part, and the tension of the spring 906 on the second hollow block 907 can make the clamping plate 904 tightly contact with the stamping part, and at the same time, the distance between the clamping plate 904 and the lower horizontal plate 901 can be automatically adjusted according to the contour of the stamping part with the continuous movement of the lower horizontal plate 901.

[0036] After the position adjustment of the clamping plate 904 is completed, the rubber pad 1005 is controlled by the second hydraulic push rod 1003 to press the upper horizontal plate 903, at this time, the upper horizontal plate 903 cannot move through the friction force between the rubber pad 1005 and the upper horizontal plate 903, and the stamping part is fixed on the workbench 1 through the clamping plate 904.

[0037] When the stamping part needs to be taken away, the clamping plate 904 is separated from the stamping part through the first hydraulic push rod 8, and then the stamping part is taken away from the workbench 1.

[0038] The above is only the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
