A clamping mechanism 6 is fixedly installed on the front side of the top of the mounting plate 2, and a control component 7 is fixedly installed on the right side of the front side of the top of the mounting plate 2.

[0022] refer to Figure 2 The clamping mechanism 6 includes a cylinder 61, which is fixedly installed on the front side of the top of the mounting plate 2. A clamping plate 62 is fixedly installed at the output end of the cylinder 61. The length of the clamping plate 62 is the same as the length of the positioning stop bar 3. Support components 63 are fixedly connected to the left and right sides of the front of the clamping plate 62.

[0023] As a technical optimization of this utility model, by setting a clamping mechanism 6, which is powered by a cylinder 61, the clamping efficiency is greatly improved compared with manual clamping. Moreover, the clamping force output by the cylinder 61 is stable and can be precisely adjusted, effectively avoiding the loosening and displacement of the sofa legs during processing due to insufficient or unstable clamping force, and significantly improving the processing quality. The clamping plate 62 and the positioning stop 3 are of the same length, which can evenly clamp the sofa legs placed in the workpiece positioning slot 5, further ensuring the accuracy of positioning.

[0024] refer to Figure 2 The control component 7 includes a manual valve 71, which is fixedly installed on the right side of the front top of the mounting plate 2. The air source interface of the manual valve 71 is connected to a first air pipe 72, and the other end of the first air pipe 72 is connected to an external air source. The air source output port of the manual valve 71 is connected to a second air pipe 73, and the other end of the second air pipe 73 is connected to the air source interface of the cylinder 61.

[0025] As a technical optimization of this utility model, by setting up a control component 7 and using a manual valve 71 to control the cylinder 61, the operation is simple, and the worker can flexibly control the working state of the cylinder 61 according to the actual processing needs. The external air source is connected to the cylinder 61 through the first air pipe 72 and the second air pipe 73, which ensures a stable supply of air source, enabling the cylinder 61 to work stably and providing reliable power support for the clamping mechanism 6, thereby ensuring the efficient operation of the positioning fixture.

[0026] refer to Figure 2 The support assembly 63 includes a slide rod 631, which is fixedly connected to the left and right sides of the front abutment. Support blocks 632 are fixedly connected to the front side of the surface of the slide rod 631, and the bottom of the support blocks 632 is fixedly connected to the top of the mounting plate 2.

[0027] As a technical optimization of this utility model, by setting a support component 63, the slide rod 631 and the support block 632 in the support component 63 provide a stable support structure for the clamping plate 62. The slide rod 631 can guide the clamping plate 62 to move smoothly in the horizontal direction, preventing the clamping plate 62 from deviating or shaking during the movement, further improving the stability and accuracy of the clamping operation, and helping to improve the positioning accuracy of the metal sofa leg.

[0028] refer to Figure 2 A protective pad 8 is attached to the back of the clamping plate 62. The protective pad 8 is made of natural rubber.

[0029] As a technical optimization of this utility model, by setting a protective pad 8, the natural rubber protective pad 8 can prevent the clamping plate 62 from directly contacting the surface of the sofa leg when clamping the metal sofa leg, thus preventing scratches on the surface of the sofa leg and protecting the appearance quality of the sofa leg. At the same time, the elasticity of natural rubber can further enhance the clamping effect, making the sofa leg more stable during the processing.

[0030] refer to Figure 2 The front end of the slide rod 631 is fixedly connected to a limiting block 9, and the diameter of the limiting block 9 is larger than the diameter of the slide rod 631.

[0031] As a technical optimization of this utility model, by setting a limiting block 9, the limiting block 9 at the front end of the slide bar 631 can prevent the pressing plate 62 from extending excessively during the movement, thus playing a limiting protection role and avoiding damage to the cylinder 61 due to the excessive extension of the pressing plate 62.

[0032] refer to Figure 2 Mounting lugs 10 are fixedly connected to the front and rear sides of the left side and the front and rear sides of the right side of the mounting plate 2.

[0033] As a technical optimization of this utility model, by setting up the mounting lugs 10, the mounting lugs 10 around the mounting plate 2 facilitate the installation of the entire positioning fixture onto other equipment, or facilitate lifting during transportation, thereby improving the installation convenience and transportation convenience of the positioning fixture, which is conducive to improving the equipment assembly and debugging efficiency in the production process.

[0034] The working principle and usage process of this utility model are as follows: First, the mounting plate 2 of the positioning fixture is securely fixed to the top of the processing table 1 using a suitable connection method. This ensures that the fixture will not shift due to external vibration or operational influence during the entire processing process. Next, the operator moves the metal sofa leg to be processed to the fixture. Based on the shape and size of the workpiece positioning groove 5 formed by the positioning stop 3 and the dividing block 4, the sofa leg is placed into the groove. The positioning stop 3 acts as a rear limit, and the spacing between the dividing blocks 4 is designed according to the specifications of the sofa leg, allowing the sofa leg to quickly and accurately find its placement position, achieving initial positioning. Its principle is based on mechanical positioning, utilizing the adaptability of shape and size to guide the sofa leg to the predetermined position, reducing positioning time, improving production efficiency, and reducing positioning errors caused by arbitrary manual placement. Then, the operator operates to open the manual valve 71. Gas from an external air source enters the manual valve 71 through the first air pipe 72, and then is delivered to the air source interface of the cylinder 61 through the second air pipe 73. Under the drive of the air source, its… The output end extends, pushing the clamping plate 62 towards the positioning stop 3. During the movement, the clamping plate 62 slides smoothly on the support block 632 via the slide rod 631, ensuring accurate movement direction. This process is based on pneumatic transmission, using gas pressure to convert into mechanical power, driving the cylinder 61 to work, thereby achieving smooth and precise movement of the clamping plate 62. It clamps the placed sofa leg from the top front side of the mounting plate 2. When the clamping plate 62 firmly presses the sofa leg against the positioning stop 3, the sofa leg is fixed. Afterwards, the metal sofa leg is in a stable and precise positioning state within the fixture. The processing equipment is started to drill holes in the mounting plate 2 at the top of the sofa leg. After completing the processing step, the operator closes the manual valve 71, cuts off the air supply to the cylinder 61, and the gas in the cylinder 61 is discharged. The output end retracts, driving the clamping plate 62 back to its initial position. At this time, the operator can remove the processed metal sofa leg from the workpiece positioning slot 5, completing one processing cycle. After removing the sofa leg, the positioning and processing operation of the next batch of sofa legs can be carried out.

[0035] In summary, this positioning fixture for processing metal sofa legs, by setting up a positioning stop 3, dividing blocks 4, and a workpiece positioning groove 5, with the positioning stop 3 set on the top rear side of the mounting plate 2 and cooperating with multiple dividing blocks 4 to form a precise workpiece positioning groove 5, enables the sofa leg to quickly find the correct placement position, and can quickly and accurately position the metal sofa leg, greatly improving positioning efficiency. It solves the problems of some fixtures relying on manual clamping, which is complicated to operate, consumes a lot of manpower, and is difficult to control the clamping force accurately, making the sofa leg easy to loosen and shift during processing, seriously affecting the processing quality. On the other hand, some fixtures that use simple mechanical clamping, although the clamping force is enhanced, have a slow response and cannot keep up with the pace of high-efficiency production.
