DETAILED DESCRIPTION
[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0024] The directions mentioned in this specification are based on the directions shown in the drawings and only represent relative positions, not absolute positions.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown together, a transmission multi-station bearing press-fitting device includes a bracket 10, a workbench 12 is mounted on the bracket 10, and a plurality of workpiece supports 20 are mounted on the workbench 12. In this embodiment, the workbench 12 is a square structure, and there are four workpiece supports 20, which are respectively mounted in the middle of the four side edges of the workbench 12. A plurality of support columns 14 are vertically mounted on the workbench 12. In this embodiment, there are five support columns 14, which are respectively mounted at the four corners and the center of the workbench 12. A mounting plate 16 is commonly provided on the top of each support column 14, and each workpiece support 20 is located between the workbench 12 and the mounting plate 16. A waist hole 160 is provided on the mounting plate 16, and a press 40 that can slide along the waist hole 160 is installed in the waist hole 160, and a press head 42 is installed at the lower end of the press 40. In this embodiment, the press head 42 is preferably installed on the press 40 through a quick-change joint, so that the press head can be quickly replaced when the press-fit product is replaced. In the present embodiment, two waist holes 160 are provided, and a press 40 is installed in each of the two waist holes 160. The two presses 40 correspond to two workpiece supports 20 respectively, that is, when the press 40 is located at one end of the waist hole 160, the press 40 is located directly above one workpiece support 20, and the bearing can be pressed into the workpiece on the workpiece support 20; when the press 40 slides to the other end of the waist hole 160, the press 40 is located directly above the other workpiece support 20, and the bearing is pressed into the workpiece on the workpiece support 20.
[0026] like Figure 1 and Figure 2As shown together, the press 40 is fixedly mounted on the press moving plate 50, and the press moving plate 50 is driven by the power device to slide along the waist hole 160, thereby driving the press 40 to slide in the waist hole 160. Two limiters are relatively installed on the mounting plate 16 located on one side of the waist hole 160, and the press moving plate 50 is provided with a protruding positioning block 52 on the side facing the two limiters. The two limiters are respectively arranged at the two end positions of the waist hole 160, which play a role in limiting and positioning the press 40. When the positioning block 52 hits the limiter, the power device drives the press moving plate 50 to stop sliding, that is, it reaches the top of a workpiece support 20, and the press fitting work can be carried out. Two limiters are arranged on the sides of the two waist holes 160, and the limiters are arranged on the sides away from the two waist holes 160.
[0027] like Figure 1 As shown, the limiting member includes a limiting block 60 fixed on the mounting plate 16. In this embodiment, the limiting block 60 is L-shaped, that is, it is composed of two perpendicular parts, wherein the horizontal part is fixed on the mounting plate 16, and a buffer 62 is installed on the vertical part. The buffer 62 can buffer the impact force between the press moving plate 50 and the limiting member.
[0028] like Figure 1 As shown, the preferred power device of this embodiment is a guide rail cylinder 30, which is installed between the corresponding waist hole 160 and the limit piece, and the press moving plate 50 is fixed on the slider of the guide rail cylinder 30. The guide rail cylinder 30 can not only drive the press moving plate 50 to slide, but also has a guiding function, which can ensure that the press 40 slides in a straight line in the waist hole 160.
[0029] like Figure 1 and Figure 2 As shown together, a positioning cylinder 70 is installed on the side of one of the waist holes 160. The positioning cylinder 70 and the stopper are located on the same side of the waist hole 160. After the piston rod of the positioning cylinder 70 is extended, it is located between the two stoppers, that is, the positioning cylinder 70 is located in the middle of the waist hole 160, and the direction in which the piston rod of the positioning cylinder 70 is extended is perpendicular to the extension direction of the waist hole 160. When the press 40 completes the press-fitting at a workpiece support 20 and needs to slide away to change the workpiece, in order to prevent the press 40 from colliding with a higher workpiece on another workpiece support 20, the piston rod of the positioning cylinder 70 will extend to block the positioning block 52 of the press moving plate 50, thereby preventing the press 40 from continuing to slide and avoiding collision with the workpiece.
[0030] like Figure 3 and Figure 4As shown in common, the four workpiece supports 20 are all equipped with workpiece pillars 26 for supporting the workpieces and positioning pillars 23 for positioning the workpieces. Since each workpiece support 20 is used to fix different workpieces, the heights, quantities and installation positions of the workpiece pillars 26 and positioning pillars 23 on different workpiece supports 20 are different, so that the multi-station bearing press-fitting device of the utility model can be used to press-fit different workpieces, thereby improving the versatility of the device. Since the workpiece pillars 26 and positioning pillars 23 on the workpiece supports 20 are only different in height, quantity and installation position, only one workpiece support 20 is used as an example for detailed description below.
[0031] like Figure 3 and Figure 4 As shown together, the workpiece support 20 includes a bottom plate 21 fixed on the workbench 12, an upper plate 22 is fitted and fixed on the bottom plate 21, a workpiece support 26 is fixedly mounted on the upper plate 22, and a positioning column 23 is movably mounted on the upper plate 22. The positioning column 23 includes a positioning column base 232, a positioning column body 230 is vertically fixed on the positioning column base 232, and a positioning pin 234 adapted to the positioning hole on the workpiece is provided at the top of the positioning column body 230. A positioning column mounting hole 220 is provided on the upper plate 22, and the positioning column base 232 is located in the positioning column mounting hole 220. The size of the positioning column mounting hole 220 is larger than the size of the positioning column base 232, and the positioning column base 232 can move forward, backward, left and right in the positioning column mounting hole 220. The positioning column base 232 is constrained in the positioning column mounting hole 220 in the vertical direction by the positioning column pressure plate 24, that is, a positioning column through hole 240 is provided in the center of the positioning column pressure plate 24, and the positioning column body 230 passes through the positioning column through hole 240. The positioning column pressure plate 24 is pressed on the positioning column base 232 and is fixed to the upper plate 22 by the pressure plate bolt 242, thereby fixing the positioning column base 232 in the positioning column mounting hole 220 in the vertical direction. The positioning column base 232 is constrained in the positioning column mounting hole 220 in the horizontal direction by the positioning bolts 224, that is, each horizontal thread of the four side walls of the positioning column mounting hole 220 is installed with a positioning bolt 224, and the positioning bolt 224 installed on the side wall located at the edge of the upper plate 22 is inserted into the positioning column mounting hole 220 through the horizontal thread of the side of the upper plate 22; the upper plate 22 is provided with a bolt mounting hole 222 at a position close to the positioning column mounting hole 220, and the positioning bolt 224 installed on the side wall located inside the upper plate 22 is inserted into the positioning column mounting hole 220 through the horizontal thread of the bolt mounting hole 222, and the positioning column base 232 is fixed in the horizontal direction by four positioning bolts 224. When the position of the positioning column 23 needs to be adjusted, it is only necessary to rotate each positioning bolt 224 counterclockwise, move the positioning column base 232 to an appropriate position, and then rotate each positioning bolt 224 clockwise to fix the positioning column base 232.
[0032] In summary, the utility model transmission multi-station bearing pressing equipment has strong versatility, occupies little space, has high pressing efficiency, can effectively reduce the number of pressing equipment required in the transmission assembly process, and reduce the production cost of the enterprise.
[0033] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
