[0025] refer to Figure 1 and Figure 2An embodiment of the present application provides a small fork frame pressing tool, including a base 10 and four telescopic elements 60. A workpiece support seat 20, two first positioning shafts 30 and two second positioning shafts 40 are arranged on the top of the base 10, wherein the workpiece support seat 20 has a support bottom 21 and a limiting side portion 22 symmetrically arranged on the outer side of the support bottom 21, and the gap between the two limiting side portions 22 located in the same symmetrical direction is greater than the width dimension of the small fork frame 50, so that the small fork frame 50 can be placed on the support bottom 21, and there is also a movable gap between the limiting side portions 22 on both sides; wherein the two first positioning shafts 30 and the two second positioning shafts 40 are symmetrically distributed in the width direction of the small fork frame 50, respectively, and the first positioning shaft 30 is used to sleeve the inner gear small bushing 31, and the second positioning shaft 40 is used to sleeve the inner gear large bushing 41, in addition, after the small fork frame 50 is placed in place on the workpiece support seat 20, the two first positioning shafts 30 are opposite to the small bushing hole 501 at the inner gear of the small fork frame 50, and the two second positioning shafts 40 are opposite to the large bushing hole 502 at the inner gear of the small fork frame 50;

[0026] The four telescopic elements 60 are symmetrically distributed at both ends of the small fork frame 50 in the width direction. At the same time, the telescopic axes of the four telescopic elements 60 are respectively used to sleeve the small outer bushing 61 and the large outer bushing 62. The telescopic element 60 used to sleeve the small outer bushing 61 faces the two first positioning axes 30, and the telescopic element 60 used to sleeve the large outer bushing 62 faces the two second positioning axes 40.

[0027] In the specific operation process, firstly, a small bushing is sleeved on the first positioning shaft 30 and the telescopic shaft of the telescopic element 60 facing the first positioning shaft 30, and a large bushing is sleeved on the second positioning shaft 40 and the telescopic shaft of the telescopic element 60 facing the second positioning shaft 40, and then the small fork frame 50 is placed on the support bottom 21, and the posture of the small fork frame 50 is adjusted so that the small bushing hole 501 and the large bushing hole 502 at the inner position of the small fork frame 50 are respectively facing the first positioning shaft 30 and the second positioning shaft 40, and then the left fork frame 50 is controlled to move. The telescopic element 60 on the side (or right side) is extended synchronously, and cooperates with the first positioning shaft 30 and the second positioning shaft 40 on the left side (or right side) to press the two small bushings and the two large bushings on the left side of the small fork frame 50 into place respectively. During this period, the small fork frame 50 will move to the right under the pressure of the telescopic element 60, but will not touch the limiting side 22 on the right side before the bushing is pressed into place. Then, the small bushing and the large bushing on the right side of the small fork frame 50 are pressed into place in the same way, which has high working efficiency and is not easy to damage the bushing.

[0028] The telescopic elements 60 are implemented as hydraulic cylinders, and the telescopic elements 60 on the same side can be controlled to extend or retract synchronously according to the timing and amount of oil supply through a mature hydraulic control system.

[0029] In one embodiment, the workpiece support seat 20 is composed of four L-shaped support plates 23, and the four L-shaped support plates 23 are symmetrically distributed in the width direction of the small fork frame 50, and in the length direction of the small fork frame 50, the first positioning axis 30, the L-shaped support plate 23 and the second positioning axis 40 are staggered in sequence, so as to provide stable support for the small fork frame 50 and ensure the stability of the press-fitted bushing of the small fork frame 50, wherein the two vertical parts of the L-shaped support plate 23 located in the same symmetrical direction are respectively located on the outside to form a limiting side 22, and the two horizontal parts are respectively located on the inside to form a support bottom 21.

[0030] In one embodiment, the small fork frame 50 has a relative head end 51 and tail end 52 along the length direction, wherein the small bushing hole 501 is close to the head end 51, and the base 10 is provided with a positioning tail seat 53 at the end away from the first positioning axis 30, and the distance between the first positioning axis 30 and the positioning tail seat 53 is greater than the length dimension of the small fork frame 50, thereby the positioning tail seat 53 can provide a rough positioning for the placement of the small fork frame 50, so that the small fork frame 50 can be placed at the support bottom 21 quickly and conveniently, saving working time.

[0031] Further preferably, the positioning tailstock 53 includes a positioning plate 531 vertically connected to the top of the base 10, and the side of the positioning plate 531 and the surface of the base 10 are vertically connected by a rib plate 532. The positioning plate 531 has a small volume, which can save raw materials while playing a positioning role. In addition, the rib plate 532 can effectively improve the positioning stability of the positioning plate 531 and extend the service life of the positioning plate 531.

[0032] Further preferably, the rib plate 532 is located on the inner surface of the positioning plate 531, and the rib plate 531 is a trapezoidal rib plate, and the top of the trapezoidal rib plate is a slope structure, which gradually inclines from one end close to the positioning plate 531 to the end away from the positioning plate 531 toward the direction close to the base 10, thereby making the overall structure of the pressing tool more compact, reducing the occupied space, and facilitating use. In addition, by setting the slope structure, interference with the positioning and placement of the small fork frame 50 can be avoided.

[0033] In one embodiment, the first positioning shaft 30 and the second positioning shaft 40 are respectively connected to the base 10 through a positioning seat 32, and a guide rail 11 is arranged on the top of the base 10, wherein the guide rail 11 extends along the symmetrical direction. Correspondingly, a slider 321 is arranged at the bottom of the positioning seat 32 for slidingly cooperating with the guide rail 11, and a plurality of positioning holes 101 are sequentially arranged at the top of the guide rail 11 along the extension direction, and a positioning piece (not shown in the figure) cooperating with the positioning hole 101 is installed on the slider 321. In this way, the distance between the first positioning shaft 30 and the second positioning shaft 40 can be flexibly adjusted by moving the first positioning shaft 30 and / or the second positioning shaft 40 on the guide rail 11, and the first positioning shaft 30 and / or the second positioning shaft 40 can be fixed on the guide rail 11 through the positioning piece after being adjusted into place, so that the sleeve pressing tool is suitable for the installation of bushings of small fork frames 50 of different width specifications, and has a wide range of applications, wherein the positioning piece can be a positioning pin or a positioning screw.
