Description

Technical Field

[0001] This utility model relates to the field of workpiece manufacturing technology, specifically to a piston pressing device for workpieces. Background Technology

[0002] When processing non-standard workpieces, a piston needs to be pressed into the workpiece according to the processing requirements to form the corresponding processed product. Traditional processing methods mostly employ manual or semi-automatic assembly, pressing the piston into the corresponding assembly position within the workpiece according to the processing needs. Manual assembly is time-consuming and labor-intensive, increasing the workload of workers. Most semi-automatic equipment only has corresponding push-in pins for piston assembly, achieving only the single function of pushing the piston into the workpiece, and cannot guarantee the integrity of the assembly between the piston and the workpiece, affecting the quality of the subsequent product. Therefore, we propose a piston pressing device for workpieces. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a piston pressing device for a workpiece, including a support frame 1, with at least two sets of support frames 1. The two sets of support frames 1 are symmetrically fixedly assembled on the surface of a workbench in the production line. A first actuating cylinder 2 is fixedly assembled on the top of each of the two sets of support frames 1. An assembly frame 3 is fixedly assembled on the actuating end of the first actuating cylinder 2. The first actuating cylinder 2 is connected to a corresponding air pump in the production line. The air pump is controlled by a controller in the production line so that the output end of the first actuating cylinder 2 can drive the assembly frame 3 to move along the Y-axis. A second actuating cylinder 4 is fixedly assembled on the surface of the assembly frame 3. A first actuating frame 5 is fixedly assembled on the output end of the second actuating cylinder 4. The second actuating cylinder 4 can drive the first actuating frame 5 to move in the X-axis direction. The second actuating cylinder 4 is also controlled by a corresponding air pump connected in the production line. Through the cooperation of the first actuating cylinder 2 and the second actuating cylinder 4, the position of the entire piston pressing device can be adjusted in both the Y-axis and X-axis directions, making it convenient for the device to move above the feeding equipment for material handling.

[0016] The side wall of the first action frame 5 is fixedly equipped with an electric telescopic rod 6. The output end of the electric telescopic rod 6 is fixedly connected to the second action frame 7. The electric telescopic rod 6 is electrically connected to the power supply and controller in the production line. The electric telescopic rod 6 can drive the second action frame 7 to move along the Z-axis.

[0017] The top of the second action frame 7 is fixedly connected with limiting shafts 81 that are symmetrically distributed on the left and right. The side wall of the first action frame 5 is fixedly equipped with a limiting frame 82. The limiting shafts 81 pass through the limiting frame 82 and are slidably connected to the limiting frame 82. The limiting component 8, which is composed of the limiting shafts 81 and the limiting frame 82, limits the movement stroke of the second action frame 7, improves the stability of the movement stroke of the second action frame 7, and maintains the verticality of the second action frame 7 when it moves up and down.

[0018] like Figure 3 and Figure 4 As shown, the side walls of the second action frame 7 are respectively fixedly equipped with a first pressing component 9 and a second pressing component 10. The first pressing component 9 and the second pressing component 10 have the same structure. The difference is that the first pressing component 9 and the second pressing component 10 are used to press pistons of different sizes into the workpiece. In the production line, according to the detection of the workpiece size by the sensor, the corresponding pressing component is selected and moved to the top of the workpiece to press the piston of the corresponding size into the workpiece.

[0019] Taking the first pressing assembly 9 as an example, the first pressing assembly 9 includes a first pressing cylinder 91, a second pressing cylinder 92, and a third pressing cylinder 93. The first pressing cylinder 91 is fixedly mounted on the side wall of the second actuating frame 7. The output end of the first pressing cylinder 91 is fixedly connected to a first pressing frame 94. A pressing cylinder 95 is inserted into the front end of the first pressing frame 94. The pressing cylinder 95 is snapped into the second pressing frame 96. A pressing pin 97 is slidably connected inside the pressing cylinder 95. The second pressing frame 96 is fixedly connected to the output end of the second pressing cylinder 92. The press-in pin 97 is fixedly connected to the output end of the third press-in cylinder 93. The second press-in cylinder 92 is fixedly mounted on the side wall of the first press-in frame 94, and the third press-in cylinder 93 is fixedly mounted on the side wall of the second press-in frame 96. The first press-in cylinder 91, the second press-in cylinder 92, and the third press-in cylinder 93 are respectively controlled by the air pumps connected to them. The output ends of the first press-in cylinder 91, the second press-in cylinder 92, and the third press-in cylinder 93 can respectively move along the Z-axis direction.

[0020] During the process of pressing the piston into the workpiece, the piston to be pressed into the workpiece can be picked up by the pressing cylinder 95. The piston is engaged in the pressing cylinder 95. The three-stage action of pressing the piston into the workpiece is realized by the first pressing cylinder 91, the second pressing cylinder 92 and the third pressing cylinder 93 respectively. First, the first pressing frame 94 moves downward to pre-position the workpiece. Then, the second pressing cylinder 92 drives the second pressing frame 96 downward to dock the pressing cylinder 95 with the workpiece. The pressing cylinder 95 pre-presses the piston into the workpiece. Finally, the third pressing cylinder 93 drives the pressing pin 97 to press the piston completely into the workpiece. By implementing the three-stage action mechanism, the accuracy of the piston and workpiece assembly position and the completeness of the piston being pressed into the workpiece can be improved, thereby improving the product quality of the workpiece.

[0021] Working principle: During the piston assembly process of the workpiece, such as Figure 1As shown, the workpiece is moved to the corresponding workstation of this device by a mobile device in the production line. When the workpiece reaches the assembly position, the first actuating cylinder 2 first drives the assembly frame 3 to move backward and pick up the material in the feeding equipment. The piston to be pressed into the workpiece is picked up and put into the pressing cylinder 95. Then, according to the detection of the sensor, the size of the piston to be pressed into the workpiece is determined. Through the cooperation of the first actuating cylinder 2 and the second actuating cylinder 4, the first pressing assembly 9 is moved above the workpiece. During the process of the piston being pressed into the workpiece, the first pressing frame 94 first contacts the workpiece to pre-fix the workpiece. Then, the second pressing cylinder 92 drives the second pressing frame 96 and the pressing cylinder 95 to descend. The pressing process of the pressing cylinder 95 can pre-press the piston into the workpiece. Finally, the third pressing cylinder 93 drives the pressing pin 97 to complete the complete pressing of the piston into the workpiece. The whole process is simple and fast, and the assembly accuracy and integrity between the piston and the workpiece are guaranteed.
