[0002] With the continuous development of the manufacturing industry, automation and intelligent production have become key drivers of industrial progress. This is especially true in the field of precision machining, which places higher demands on precise positioning and stable clamping of workpieces. Traditional clamping devices, which often rely on manual adjustment, are not only inefficient but also unable to meet the precise positioning requirements in complex working conditions.

[0003] In recent years, with the continuous advancement of pneumatic technology, mechanical design and material science, various automated clamping devices have emerged. While improving production efficiency, they have also greatly improved processing accuracy and product quality.

[0004] However, although there are many types of automatic clamping equipment on the market, most products still have problems such as complex structure, high cost, and poor adaptability.

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, an auxiliary clamping device for workshop manufacturing is provided in an embodiment of the present utility model.

[0024] It includes a positioning base plate 1, a first vertical plate 3 is welded to the upper part of the positioning base plate 1, a tool table 6 is welded to the upper part of the first vertical plate 3, a main processing hole 9 is opened on the tool table 6, and an electric tool mounting bracket 7 is welded on the tool table 6 for installing electric tools, such as a drilling device. After the drill bit passes through the main processing hole 9, the workpiece can be processed.

[0025] The upper part of the power tool mounting frame 7 is connected to the auxiliary mounting plate 8 by bolts, and the auxiliary mounting plate 8 is provided with a mounting hole. The lower part of the tool table 6 is provided with a first cylinder 14, and the piston rod of the first cylinder 14 is connected to the sliding table 12 through an extension rod 19. A workpiece mounting plate 11 is welded to the left side of the sliding table 12, and a positioning hole 15 is provided on the workpiece mounting plate 11. A heightening bracket 18 is welded to the upper part of the positioning base plate 1, and a micro cylinder 17 is fixedly connected to the heightening bracket 18. The upper end of the piston rod of the micro cylinder 17 is fixedly connected to a positioning pin. The lower part of the sliding table 12 is fixedly connected to a slider 21, and a slide groove 22 is provided on the sliding table 12.

[0026] A connecting plate 13 is welded to the left side of the positioning base plate 1, and the connecting plate 13 is connected to the first cylinder 14 by bolts. The upper part of the sliding table 12 is connected to the positioning protrusion 20 by a hinge. When the main processing hole 9 is not in use, it can be flipped to the side close to the main processing hole 9 to play a positioning role.

[0027] An opening for the first cylinder 14 to pass through is formed on the first vertical plate 3 , and a switch 4 is provided on the first vertical plate 3 for controlling the extension and retraction of the first cylinder 14 .

[0028] A plurality of second vertical plates 2 are welded to the upper portion of the positioning base plate 1 , and positioning grooves are provided on the second vertical plates 2 .

[0029] A positioning block 23 is welded to the lower portion of the workpiece mounting plate 11 , and screw holes 16 are formed on the workpiece mounting plate 11 .

[0030] An auxiliary processing hole 10 is opened on the tool table 6, and an auxiliary tool mounting frame 5 is welded to the tool table 6.

[0031] Working Principle: To use, the desired power tool, such as a drill or grinder, is mounted on the power tool mounting bracket 7 on the tool table 6. Bolts are used to secure the power tool in place through the mounting holes on the auxiliary mounting plate 8. This design allows for quick replacement of different power tools, enhancing the versatility and flexibility of the device.

[0032] The workpiece to be processed is mounted on the workpiece mounting plate 11. The workpiece mounting plate 11 is connected to the piston rod of the first cylinder 14 via a sliding platform 12. A slider 21 is provided at the bottom of the sliding platform 12, which cooperates with a slide groove 22 to ensure precise movement of the workpiece mounting plate 11.

This process ensures precise alignment of the workpiece and improves machining accuracy.

[0034] The positioning pin on the piston rod of the micro cylinder 17 is inserted into the positioning hole 15 on the workpiece mounting plate 11 to further fix the position of the workpiece.

[0035] The power tool is started to perform drilling, grinding or other processing operations on the workpiece through the main processing hole 9 or the auxiliary processing hole 10 on the tool table 6.

[0036] After the processing is completed, the first cylinder 14 is controlled by the switch 4 to retract the piston rod, so that the sliding table 12 and the workpiece mounting plate 11 are reset. The processed workpiece is removed, a new workpiece is installed, and the above steps are repeated for the next processing.
