Description
Technical Field
[0001] This utility model relates to the technical field of shaft core assembly equipment, and in particular to an automatic shaft core pressing machine. Background Technology
[0002] For pivot-type products, such as drive arms and driven arms, the main body needs to rotate around a pivot (shaft core). Each pivot is located at its end and rotatably connected to the pivot. In existing technology, the installation of the pivot core for these products lacks automated equipment for automatic assembly, resulting in low production efficiency and poor product consistency. Utility Model Content
[0003] The purpose of this invention is to provide an automatic shaft core pressing machine with a simple and reasonable structural design, stable and reliable operation, convenient use, and high assembly efficiency.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] An automatic shaft core pressing machine includes a frame, a worktable, a workpiece fixing slide, a positioning fixture, a pin feeding assembly, and a pressing shaft assembly;
[0006] The frame is vertically arranged, with a horizontal worktable on top;
[0007] A workpiece fixing slide is horizontally provided above the worktable, and a positioning fixture is provided above the workpiece fixing slide; the positioning fixture limits and fixes the workpiece on the workpiece fixing slide.
[0008] The pressure shaft assembly is located above the workpiece fixing slide and includes an electric cylinder, a pressure rod, and a pressure sensor. When the pressure rod is in operation, it corresponds vertically to a vertically positioned pin. The pressure shaft assembly also includes a lateral displacement assembly, which can adjust the position of the pressure shaft assembly laterally (as multiple pins need to be pressed, their positions differ). The lateral displacement assembly includes a lateral movement motor, a lead screw, a sliding sleeve, a connecting push plate, a pressure shaft mounting base, a slider, and a slide rail. The lateral movement motor is horizontally mounted on the top of the frame, its output shaft connected to the lead screw, and the sliding sleeve is fitted onto the lead screw for meshing transmission. A connecting push plate is fixed to the outer wall of the sliding sleeve, connecting the push plate to the pressure shaft mounting base. A slider is located at the bottom of the pressure shaft mounting base, and a slide rail is fitted onto the slide rail, which is horizontally mounted on the top of the frame. When the lateral movement motor operates, it can push the pressure shaft mounting base (pressure shaft assembly) to move laterally along the slide rail.
[0009] The pin feeding assembly includes an ejector cylinder, a clamping and tilting cylinder, a pick-and-place cylinder, and a feeding box. The feeding box is vertically arranged, with a pin outlet at its bottom. A horizontally arranged ejector cylinder is located on one side of the outlet, its output shaft connected to the outlet to eject the pin horizontally. A clamping and tilting cylinder is located on the other side of the outlet, clamping one end of the pin and tilting it upwards by 90° to make it vertical. Above the clamping and tilting cylinder is a vertically arranged pick-and-place cylinder with grippers at its bottom. These grippers grasp the vertically arranged pin and move it above the workpiece, inserting it into the pin mounting hole of the workpiece. Preferably, the pick-and-place cylinder is vertically fixed to a cross slide and can move vertically and horizontally along the slide rails on the cross slide. The cross slide is existing technology and will not be described in detail here.
[0010] The workpiece fixing slide includes a second slide rail, a second slider, a slide base, a forward / backward motor, a second lead screw, and a second sliding sleeve. The second slide rail is horizontally positioned above the worktable, and the second slider is fitted onto it. A horizontally positioned slide base is fixed to the top of the second slider. The forward / backward motor is horizontally positioned below the worktable, and its output shaft is connected to the second lead screw. The second sliding sleeve is fitted onto the second lead screw, and they engage for transmission. The outer wall of the second sliding sleeve is connected to a second connecting push plate, which is fixedly connected to the slide base. The forward / backward motor drives the slide base to move back and forth along the second slide rail. When a workpiece needs to be installed on the workpiece fixing slide (or after the pin is pressed in), the forward / backward motor pushes the workpiece fixing slide forward to facilitate the installation and removal of the workpiece. When the pin needs to be pressed into the workpiece, the forward / backward motor pushes the workpiece fixing slide directly below the pressure shaft assembly.
[0011] The positioning fixture includes a limiting base and four side limiting baffles; its purpose is to restrict the six degrees of freedom of the workpiece, thus fixing the workpiece in a fixed position. Both the limiting base and the limiting top cover are equipped with workpiece slots. The limiting top cover is fixed to a top cover lifting seat; the top cover lifting seat includes a lifting motor and a lifting pressure plate. The lifting motor is vertically fixed to the worktable, and its output shaft is connected to the horizontally positioned lifting pressure plate. The bottom of the lifting pressure plate is connected to the horizontally positioned limiting top cover.
[0012] Preferably, the bottom of the workpiece fixing slide is provided with a top shaft assembly, which works in conjunction with the pressing shaft assembly to press the pin into the workpiece and plays a buffering role; after the pin is pressed in, if it is pressed in too deeply, the position of the pin can be finely adjusted by the top shaft assembly.
[0013] The top shaft assembly includes a top shaft cylinder, a top rod and slide rail three, and a slide block three; the top shaft cylinder is vertically arranged, and its output shaft is connected to the upwardly vertically arranged top rod, with the top rod and the pressure rod corresponding vertically.
[0014] Brief description of equipment operation:
[0015] 1. Manually place the upper support product into the fixture and start the automatic mode. Perform the following actions:
[0016] 2. The shaft uses a spring clip for material storage. The shaft is separated by a motor, and the material is automatically discharged and installed.
[0017] 3. Use the XY axis pneumatic clamp to hold the shaft core, move the clamp above the hole and put the shaft core in; load 4 shafts onto the clamp at a time.
[0018] 4. The cylinder pre-presses the shaft core on the fixture flat.
[0019] 5. The equipment moves the product to the pressing station, where an 8-ton electric cylinder is used for pressing. Four products are automatically pressed in sequentially. The pressure is read, and a KO / NG alarm is triggered.
[0020] 6. After pressing the product, move it forward and manually pick up the assembled workpiece and place it on the conveyor belt to flow into the next process.
