[0002] Press-Fitting is a key assembly technology in the manufacturing industry. Its core lies in the assembly method of forcibly inserting a part (usually called an insert or bushing) into another part (a base part or a hole part). This assembly technology uses external force to make the size of the insert slightly larger than the inner diameter of the hole part, so as to form an interference fit after assembly and achieve a tight connection. The press-fitting process can be done manually or using special equipment such as hydraulic presses, pneumatic presses or mechanical presses, depending on the required pressure and production volume.

[0003] However, in the conventional operation of placing parts into the side wall of a workpiece by press fitting, there is a challenge: when the thickness of the side wall of the workpiece is small, the strong external force during the extrusion process may cause unnecessary deformation of the workpiece structure.

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figures 1 to 6 As shown, a pressing tool of the utility model is used to press a part into a workpiece, the workpiece has a length L, a height H and a width W, the part is pressed on the side wall in the length L direction, and the pressing tool comprises: a workbench 1; an extrusion assembly 2, which is arranged on the workbench 1, the extrusion assembly 2 has a movably arranged extrusion member 3, the part is sleeved on the extrusion member 3, and the extrusion member 3 is used to press the part into the outer side wall of the workpiece along the length L direction; a support assembly 4, which is arranged on the workbench 1 and is arranged opposite to the extrusion assembly 2, the support assembly 4 has a movably arranged support member 5 and a pushing block 6 connected to the support member 5, the support member 5 can move downward along the height H direction due to the pushing block 6, and approach the workpiece and movably abut against the inner side wall in the length L direction, so as to provide support for the workpiece; a fixing assembly 7, which is arranged on the workbench 1 and movably abuts against one side in the height H direction, so as to provide fixation for the workpiece.

[0030] The specific steps of the press-fitting tool in the present scheme to press the parts into the workpiece are as follows: first, the fixing component 7 movably abuts against one side of the workpiece along the height H direction to ensure that the workpiece is firmly positioned on the workbench 1; then, the extrusion component 2 drives the extrusion member 3 and the parts thereon to approach the outer wall of the workpiece along the length L direction. At the same time, the push block 6 in the support component 4 moves downward synchronously along the height H direction, prompting the support member 5 connected thereto to approach the inner wall of the workpiece along the length L direction. Even if the thickness of the side wall of the workpiece is relatively small, when the extrusion member 3 presses the part into the outer wall of the workpiece along the length L direction, the support member 5 abuts against the inner wall of the workpiece along the length L direction and provides support for the workpiece, which significantly reduces the concentrated pressure on the side wall of the workpiece during the extrusion process and effectively avoids the problem of structural deformation of the workpiece caused by excessive pressure.

[0031] In order to connect the support member 5 with the pushing block 6 , a clamping portion 8 is provided at one end of the support member 5 , and a first clamping groove 9 is provided on the pushing block 6 , in which the clamping portion 8 is clamped.

[0032] like Figure 4 and Figure 5 As shown, guide bevel grooves 10 are symmetrically arranged on both sides of the clamping portion 8, and inclined protrusions 11 adapted to the guide bevel grooves 10 are arranged on both sides of the clamping grooves. The inclined protrusions 11 are movably clamped in the guide bevel grooves 10 respectively. The distance between the guide bevel groove 10 and the push block 6 gradually decreases from top to bottom in the height H direction. When the push block 6 moves downward, the inclined protrusion 11 moves downward along the guide groove, so that the support member 5 approaches the workpiece until it is movably abutted against the inner side wall in the length L direction.

[0033] Specifically, the support assembly 4 also includes: a fixed seat 12, a plurality of fixed seats 12 are arranged on the workbench 1, and a second clamping groove 13 is arranged on the fixed seat 12, and a support member 5 is movably clamped in the second clamping groove 13. The design of the second clamping groove 13 ensures that the support member 5 can be movably clamped on the fixed seat 12, which can not only maintain the stability of the support member 5, but also allow the support member 5 to move as needed; a first driving member 14, a first driving member 14 is arranged under the fixed seat 12, and the output end of the first driving member 14 is connected to a pushing block 6, and the first driving member 14 drives the pushing block 6 to rise and fall in the height H direction, thereby controlling the movement of the support member 5, and the first driving member 14 can be a cylinder, a cylinder or a motor.

[0034] Specifically, the extrusion assembly 2 also includes: a moving seat 15, a plurality of slide rails 16 are arranged on the workbench 1, and the moving seats 15 are movably arranged on the slide rails 16, the moving seats 15 are arranged opposite to the fixed seat 12, and the moving seats 15 are connected with extrusion members 3, and the moving seats 15 are used to drive the extrusion members 3 to move; a second driving member, a plurality of second driving members are arranged on the side of the workbench 1, and the output ends of the second driving members are respectively connected to the moving seats 15, and the second driving members are used to drive the moving seat 15 to move; a detection member 17, which is arranged on the moving seat 15 and electrically connected to the second driving member, and is used to detect whether the part is pressed into the workpiece, and the detection member 17 is preferably a displacement sensor.

[0035] The second driving member drives the moving seat 15 to move along the slide rail 16. As the moving seat 15 moves, the extrusion member 3 and the parts thereon gradually approach the outer wall of the workpiece in the length L direction. During the approaching process, one end of the part will begin to contact the workpiece, and the extrusion member 3 gradually applies pressure until the part is completely pressed into the predetermined position on the workpiece. At the same time, the first driving member 14 drives the pushing block 6 to move downward in the height direction H, so that the support member 5 and the inner side wall in the length direction L of the workpiece are movably abutted and gradually apply pressure, which effectively disperses the pressure of the extrusion member 3 on the side wall of the workpiece during the extrusion process. During the entire pressing process, the detection member 17 detects the pressing process of the parts throughout the entire process to ensure that the parts are pressed into place. After the parts are pressed into place, the detection member 17 transmits a signal to the second driving member, and the second driving member immediately drives in the reverse direction to drive the moving seat 15 to move in the reverse direction along the slide rail 16, so that the extrusion member 3 is separated from the part and returns to the initial position. At the same time, the first driving member 14 drives in the reverse direction to drive the pushing block 6 to move upward in the height H direction, thereby driving the support member 5 to separate from the workpiece and return to the initial position, and the pressing work is completed.

[0036] Specifically, the fixing assembly 7 includes: a third driving member 18. A plurality of third driving members 18 are arranged on the workbench 1. A fixing block 19 is arranged at the output end of each of the third driving members 18. After the workpiece is placed on the workbench 1, the third driving member 18 first drives the fixing block 19 to rotate to the top of the workpiece in the height H direction, and then drives the fixing block 19 to move downward in the height H direction to flexibly abut against one side of the workpiece, thereby fixing the workpiece.
