Description

Technical Field

[0001] The utility model belongs to the technical field of press-fitting machines, in particular to a double-station automatic press-fitting machine. Background Art

[0002] Press machines usually use output devices, such as hydraulic cylinders, electric cylinders or pneumatic cylinders, to press parts or press in interference fit parts. They are widely used in the field of mechanical processing. Usually, a suitable fixture is installed on the top of the output shaft of the press machine to press the required products.

[0003] The existing press machine has the following problems during use:

[0004] Since the output device of the press machine is relatively large, one press machine corresponds to one press position, which occupies a lot of space at the equipment use site. The waiting time during the process of pressing a single part into a finished product is long, which delays the production process.

[0005] During the manufacturing process, manual placement of the workpiece to be pressed requires identifying the front and back of the workpiece to be pressed, and the pressed parts are small and not easy to pick up. Placing parts, placing pressed parts, and taking finished products back and forth is cumbersome, has low production efficiency, and is difficult to achieve an automated process.

[0006] Manually removing materials after the press is completed wastes time, and removing materials by hand increases safety risks. Utility Model Content

[0042] See also Figure 1-Figure 11 :

[0043] like Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, the utility model provides a double-station automatic press-fitting machine, comprising a frame 1, a press-fitting device 2, and a PIN feeding mechanism 3. The PIN needle feeding mechanism 3 is located above the frame 1, and the pressing device 2 is vertically suspended above the PIN needle feeding mechanism 3. A pressing head 21 is provided below the pressing device 2. A movable pressing block 35, a left feeding fixture 321, and a right feeding fixture 322 are provided on the PIN needle feeding mechanism 3. The movable pressing block 35 can move within a limited distance of one degree of freedom. The movable pressing block 35 includes an A pressing station 341 and a B pressing station 342. The movable pressing block 35 corresponds to the positive limit at the leftmost end and the negative limit at the rightmost end. When the movable pressing block 35 moves to the positive limit, the A pressing station 341 corresponds to the left feeding fixture 321 up and down, and the B pressing station 342 corresponds to the pressing head 21 up and down; when the movable pressing block 35 moves to the negative limit, the A pressing station 341 corresponds to the pressing head 21 up and down, and the B pressing station 342 corresponds to the right feeding fixture 322 up and down. During operation, the PIN needle 37 falls into the left loading fixture 321 and the right loading fixture 322 respectively. When the movable pressing block 35 moves to the positive limit, the PIN needle 37 in the left loading fixture 321 falls into the A pressing station 341. At the same time, the B pressing station 342 is under the pressing device 2. After the workpiece 6 to be pressed is placed at the B pressing station 342 manually or by a robot, the pressing head 21 presses. When the movable pressing block 35 moves to the negative limit, the PIN needle 37 in the right loading fixture 322 falls into the B pressing station 342. At the same time, the A pressing station The workstation 341 is located below the pressing device 2. After a workpiece 6 to be pressed is placed manually or by a robot at the pressing station A and is pressed by the pressing head 21, the pressing block 35 is moved to the positive limit and reciprocates to repeat the above action, that is, the pressing block 35 is moved back and forth. When the pressing station A 341 is loading, the pressing station B 342 is pressing; when the pressing station B 342 is loading, the pressing station A 341 is pressing. Loading and pressing are carried out simultaneously, and the various actions do not interfere with each other and are completed independently, thereby reducing the waiting time of the pressing device 2 and improving work efficiency.

[0044] like Figure 3 , Figure 4 , Fig.10 As shown, the ejector rod 71 in the movable press-fitting block 35 moves left and right with the movable press-fitting block 35. When the ejector rod 71 does not move to the press-fitting position, the driving rod 72 on the press-fitting block fixed seat 36 and the ejector rod 71 do not correspond to each other. Figure 3 as shown; Fig.10As shown, when the mobile press block 35 moves the ejector rod 71 to the press position, the driving rod 72 can correspond to the ejector rod 71 up and down. The left loading fixture 321 includes a loading block 3211, and the loading block 3211 is provided with at least one loading hole 3213. The bottom surface of the loading block is the lower end surface 3212 of the loading block. The A press station 341 includes a pressing plate 3411. The surface of the pressing plate 3411 is flush with the surface of the mobile press block 35. At least one PIN hole 3414 is provided on the pressing plate 3411. The PIN feeding needle mechanism 3 is provided with a workpiece 6 to be pressed. The PIN needle 37 is in the press-fitting hole 62 of the workpiece 6 to be press-fitted. During press-fitting, the press-fitting hole 62 and the PIN hole 3414 can correspond to each other up and down. At least one press-fitting hole 62 is set on the workpiece 6 to be press-fitted. The distance between the lower end surface 3212 of the loading block and the upper end surface 3412 of the press-fitting plate is X. The length of the PIN needle 37 is longer than the PIN hole 3414. After the PIN needle 37 falls into the PIN hole 3414, the protruding distance is Y, and X is greater than Y. Since the right loading fixture 322 has the same structure as the left loading fixture 321, and the B pressing station 342 has the same structure as the A pressing station 341, the specific way in which the PIN pin 37 falls into the A pressing station 341 is described in detail based on the structure of the left loading fixture 321 and the A pressing station 341: in the initial state, the middle part of the A pressing station 341 and the B pressing station 342 on the mobile pressing block 35 corresponds to the pressing head 21, and the PIN pins 37 are arranged in a vertical stack in the loading hole 3213, and the bottom surface of the bottom PIN pin 37 contacts the movable pressing block 35. However, the PIN pin 37 will not be tilted or tilted. When the movable pressing block 35 moves toward the positive limit, the bottom of the PIN pin 37 rubs against the movable pressing block 35. When the movable pressing block 35 brings the A pressing station 341 to the lower part of the left loading fixture 321, the PIN pin 37 falls into the PIN hole 3414 of the A pressing station 341. At this time, the distance of the protruding part of the PIN pin 37 is Y. The thickness Z of the bottom plate 61 of the workpiece to be pressed in this embodiment is equal to Y. This can ensure that the pressing head 21 presses the PIN pin 37 to the specified position of the workpiece 6 to be pressed. If the distance between the lower end surface 3212 of the loading block and the upper end surface 3412 of the pressing plate is too short, after the PIN pin 37 falls, the bottom of the PIN pin 37 is in the PIN hole 3414, but the top is still in the loading hole 3213. At this time, moving the pressing block 35 will break the PIN pin 37 or damage the equipment; if the distance between the lower end surface 3212 of the loading block and the upper end surface 3412 of the pressing plate is too long, after the PIN pin 37 falls, a new PIN pin 37 will continue to fall, and the left loading fixture 321 will not be able to arrange the PIN pins 37 for loading in an orderly manner.

[0045] like Figure 6As shown, the frame 1 is provided with a feeding module 5, and the feeding module 5 includes a vibration plate 51 and a discharge pipe 53. The height of the vibration plate 51 is higher than the height of the left feeding fixture 321 and the right feeding fixture 322, and the left feeding fixture 321 and the right feeding fixture 322 are fed by gravity potential energy. The discharge end of the vibration plate 51 is connected to the discharge pipe 53, and the other end of the discharge pipe 53 is connected to the left feeding fixture 321 or the right feeding fixture 322. The PIN needle 37 screened by the vibration plate 51 passes through the discharge pipe 53 by gravity and then reaches the left feeding fixture 321 or the right feeding fixture 322. Such a structure reduces the mobile alignment module and reduces the manufacturing cost of the machine. The uninterrupted feeding method also improves the feeding efficiency and reduces the corrosion of the PIN needle 37 by human hand sweat.

[0046] like Figure 2 , Figure 3 As shown, a press block fixing seat 36 is provided below the movable press block 35. The movable press block 35 is slidably arranged on the press block fixing seat 36 using a slider structure. In this embodiment, the slider structure is specifically a trapezoidal guide rail and a dovetail groove structure. The press block fixing seat 36 can provide a guiding function for the movable press block 35, so that the movable press block 35 can be more accurate in the process of moving and positioning. A power device 33 is provided on the press block fixing seat 36. The power device 33 can drive the movable press block 35 to move between the positive limit position and the negative limit position. It should be noted that the power device 33 of this embodiment can be an existing technology such as an oil cylinder, an electric cylinder, or a pneumatic cylinder. The working principle of the power device 33 will not be repeated here.

[0047] like Figure 2 The PIN needle feeding mechanism 3 is provided with a left detection device 311 and a right detection device 312, which are respectively fixed on the left and right sides of the press-fitting block fixing seat 36. When the movable press-fitting block 35 moves to the negative limit, the A press-fitting station 341 will pass through the left detection device 311, and when the movable press-fitting block 35 moves to the positive limit, the B press-fitting station 342 will pass through the right detection device 312. During the production process, the left detection device 311 and the right detection device 312 are used instead of human eyes to identify whether the PIN needle 37 is placed properly, which reduces the eye fatigue of employees and also reduces the potential safety hazards in production, thereby improving production efficiency.

[0048] like Figure 5 , Figure 7 , Fig.10As shown, the frame 1 is provided with a discharge module 4, and the discharge module 4 includes a grasping device 41, a movable module assembly 42, and a slide 44. The grasping device 41 is arranged on the movable module assembly 42, and the slide 44 is arranged directly below the grasping device 41 when the movable module assembly 42 is in a retracted state. When grasping the finished press-fitted workpiece 8, the grasping device 41 will pass through a removal outlet 43 opened at the rear of the mold base of the support of the press-fitting device 2 to grasp it. An ejector rod 71 is vertically arranged inside the lower part of the A press-fitting station 341 of the movable press-fitting block 35. When the finished press-fitting workpiece 8 is placed on the press-fitting station, the ejector rod 71 can correspond to the finished press-fitting workpiece 8 up and down to eject the finished press-fitting workpiece 8. A driving rod 72 is provided inside the press-fitting block fixing seat 36. When the A press-fitting station 341 moves to the press-fitting position, the driving rod 72 corresponds to the ejector rod 71 up and down. After the press-fitting of the press-fitted workpiece 6 and the PIN needle 37 is completed, the driving rod 72 pushes the ejector rod 71 and moves upward to eject the finished press-fitted workpiece 8 upward. The lifting drive device 451 of the driving rod 72 in this embodiment is a cylinder. After the press-fitting of the press-fitting head 21 is completed, the driving rod 72 in the press-fitting block fixing seat 36 is driven by the cylinder, and the driving rod 72 supports the ejection rod 71 in the mobile press-fitting block 35. Then the ejection rod 71 is ejected through the ejection hole 3413 to lift the finished press-fitting workpiece 8, and the mobile module assembly 42 extends, and the gripping device 41 opens to grip and clamp the finished press-fitting workpiece 8. Then the mobile module assembly 42 retracts, the gripping device 41 is released, and the finished press-fitting workpiece 8 is drawn out from the slide 44, and the driving rod 72 retracts with the cylinder output end, and the ejection rod 71 retracts into the mobile press-fitting block 35 under the action of gravity and the return spring 452. The mobile module assembly 42 of this embodiment can be an existing technology such as an electric cylinder and a cylinder, and the working principle of the mobile module assembly 42 is not repeated here.

[0049] like Fig.11 As shown, the PIN hole 3414 is arranged around the ejection hole 3413, and after the workpiece 6 to be pressed is pressed, the PIN needle 37 protrudes downward.
