Description

Technical Field

[0001] This utility model relates to the field of automatic automotive press-fitting technology, specifically to a press-fitting device that automatically switches press heads. Background Technology

[0002] In the press-fitting of precision components such as bearings and bushings in automotive rear main reducers and transfer cases, single-axis servo switching press-fitting equipment has become the most widely used equipment solution due to its balance of economy, assembly efficiency and production cycle time.

[0003] However, traditional single-axis servo press fitting equipment still has its own limitations in actual production. For example, the press heads of the press fitting equipment rely on manual replacement and adjustment, which is not only cumbersome and time-consuming, but also easily affects the consistency of the press fitting benchmark due to differences in manual operation, seriously slowing down the overall production line cycle. There are breakpoints in the production process. Traditional single-axis servo press fitting equipment can only correspond to a single press fitting station. The next workpiece can only be processed after the entire cycle of loading, positioning, press fitting, and unloading is completed at the station, resulting in low production efficiency. There is insufficient adaptability to multiple processes. When the workpiece needs to perform a multi-process composite press fitting process, traditional single-axis servo press fitting equipment is difficult to complete independently. Usually, multiple machines need to be configured and connected in series to form a production line, which is costly and the layout of the production line is lengthy. Utility Model Content

[0022] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] See Figures 1 to 2This utility model provides an automatic pressure head switching pressing device, including a frame body 1, a moving mechanism 2, a driving mechanism 3, and multiple pressure heads 4; an X-direction slide groove 101 is fixedly provided on the frame body 1, and an interval portion 102 is provided on the X-direction slide groove 101. The length of the interval portion 102 in the X direction is set to h1, and a pressure head connecting seat 105 is provided in the interval portion 102. The length of the pressure head connecting seat 105 in the X direction is set to h2, where h2 < h1; the moving mechanism 2 includes an X-direction mounting plate 201, a Z-direction mounting plate 202, an X-direction slide rail 203, and multiple Z-direction slide rails 204. The X-direction slide rail 203 is fixedly provided on the frame body 1, the X-direction mounting plate 201 is slidably connected to the X-direction slide rail 203, and the Z-direction mounting plate 202 is fixedly connected to the X-direction mounting plate 201. Specifically, the Z-direction mounting plate 202 is perpendicular to the X-direction mounting plate 204. 1. The Z-axis mounting plate 202 is disposed on the outer edge of the X-axis mounting plate 201, and multiple Z-axis slide rails 204 are spaced apart on the Z-axis mounting plate 202. Specifically, the Z-axis slide rails 204 are all perpendicular to the X-axis slide rails 203. Multiple pressure heads 4 are slidably connected to multiple Z-axis slide rails 204, and the top of the pressure head 4 can be slidably connected to the bottom of the X-axis slide groove 101 and the pressure head connecting seat 105, respectively. The drive mechanism 3 includes a servo press 301 for driving the pressure head 4 to move and a main cylinder 302 for driving the moving mechanism 2 to move. The servo press 301 and the main cylinder 302 are both disposed on the frame body 1. The bottom of the servo press 301 is connected to the top of the pressure head connecting seat 105, and the servo press 301 can drive the pressure head connecting seat 105 to pass downward through the interval 102. The main cylinder 302 is connected to the X-axis mounting plate 201.

[0024] The basic working principle of the automatic pressure head switching pressing device of this utility model is as follows: In use, by setting up the frame body 1, the moving mechanism 2, and the pressure head 4, multiple workpieces can be placed on the X-direction mounting plate 201 respectively, and located below the multiple pressure heads 4. Another workpiece can be installed on each of the multiple pressure heads 4. By setting up the driving mechanism 3, the main cylinder 302 can drive the X-direction mounting plate 201 to move along the X-direction slide rail 203, that is, it can drive the workpieces on the X-direction mounting plate 201 and the Z-direction mounting plate 201 to move. 2. The Z-axis slide rail 204 and the pressure head 4 move along the X-axis slide rail 203. Simultaneously, the pressure head 4 can also move along the X-axis slide groove 101 until it reaches the spacer 102 and slides into contact with the pressure head connecting seat 105 in the spacer 102. By setting the length of the spacer 102 in the X-axis direction to be greater than the length of the pressure head connecting seat 105 in the X-axis direction, the servo press 301 can drive the pressure head connecting seat 105 downwards through the spacer 102, that is, it can drive the pressure head 4 upwards... The workpiece moves downward and presses the workpiece on the pressure head 4 onto the workpiece on the X-axis mounting plate 201. After pressing, the servo press 301 moves upward to reset and can drive the pressure head connecting seat 105 and the pressure head 4 to reset upward. When the pressure head connecting seat 105 moves into the interval 102 of the X-axis slide rail 101, the servo press 301 stops running, and the main cylinder 302 continues to drive the X-axis mounting plate 201, other workpieces on the X-axis mounting plate 201, the Z-axis mounting plate 202, the Z-axis slide rail 204, and the pressure head 4 along the X-axis slide rail 201. 03 moves until the next pressing head 4 moves to the interval 102 and slides into connection with the pressing head connecting seat 105 in the interval 102; the pressing device of this application can complete the composite pressing of multiple processes. During the pressing process, the switching of pressing head 4 can be fully automated without manual intervention. The pressing head 4 can be switched from right to left in the following order: right, middle, left, reset, or from left to right in the following order: left, middle, right, reset. The assembly efficiency is high and can meet the pressing needs of fast-paced pressing.

[0025] See Figures 1 to 2 The present invention will be further described below with reference to a specific embodiment:

[0026] In this embodiment, see Figure 1 , Figure 2As a preferred design, the main frame 1 also includes a base 103, a mounting bracket 104 fixedly mounted on the base 103, an X-axis slide rail 203 fixedly mounted on the base 103, an X-axis slide groove 101 fixedly mounted on the mounting bracket 104, and a servo press 301 mounted on the mounting bracket 104. By setting the base 103, the stability of the main frame 1 can be improved, its anti-overturning ability can be enhanced, and its manufacturing difficulty can be reduced. By setting the mounting bracket 104, it only needs to bear a relatively strong weight and can evenly transfer the load to the base 103, thereby improving the reliability of the load bearing.

[0027] In this embodiment, see Figure 1 As a preferred design, the X-axis mounting plate 201 is provided with multiple fixing structures 211 for fixing the workpiece at intervals. The multiple fixing structures 211 are located below the multiple pressure heads 4. By setting the fixing structures 211, a unified reference can be pressed, effectively reducing manual operation errors.

[0028] In this embodiment, see Figure 1 , Figure 2As a preferred design, it also includes a positioning mechanism 5, which includes a first fixed stop 501, a second fixed stop 502, and a Y-direction telescopic stop 503. The driving mechanism 3 also includes an auxiliary cylinder 303 for moving the Y-direction telescopic stop 503. The first fixed stop 501 and the second fixed stop 502 are respectively disposed at both ends of the X-direction slide rail 203. The X-direction mounting plate 201 can abut against the first fixed stop 501 or the second fixed stop 502. One end of the Y-direction telescopic stop 503 is connected to the auxiliary cylinder 303. One end can extend onto the X-direction slide rail 203, and the X-direction mounting plate 201 can abut against the extended Y-direction telescopic stop block 503. By setting the first fixed stop block 501 and the second fixed stop block 502, the X-direction mounting plate 201 can be effectively prevented from exceeding the effective stroke of the X-direction slide rail 203 due to inertia, misoperation, etc., thus preventing derailment. This accurately defines the maximum stroke limit of the X-direction mounting plate 201, ensuring that it always moves within the designed effective range, and has good overload and impact resistance. At the same time, when the X-direction mounting plate 201 is in use, When the X-axis mounting plate 201 abuts against the first fixed stop 501, the pressure head 4 away from the first fixed stop 501 can be located in the interval 102 and slidably connected with the pressure head connecting seat 105 in the interval 102. When the X-axis mounting plate 201 abuts against the second fixed stop 502, the pressure head 4 away from the second fixed stop 502 can be located in the interval 102 and slidably connected with the pressure head connecting seat 105 in the interval 102. By setting the Y-axis telescopic stop 503, when the X-axis mounting plate 201 moves along the X-axis slide rail 203, the pressure head 4 can be located in the interval 102 and slidably connected with the pressure head connecting seat 105 in the interval 102. The auxiliary cylinder 303 drives the Y-direction telescopic stop block 503 to extend along the Y direction to the X-direction slide rail 203. When the X-direction mounting plate 201 abuts against the Y-direction telescopic stop block 503, it can stop moving forward. At the same time, it can make the pressure head 4 located in the interval 102 and slide connected with the pressure head connecting seat 105 in the interval 102, so that the servo press 301 can drive the pressure head 4 to perform pressing. After pressing, the auxiliary cylinder 303 drives the Y-direction telescopic stop block 503 to retract and reset along the Y direction, and the X-direction mounting plate 201 continues to move along the X-direction slide rail 203.

[0029] In this embodiment, see Figure 1 As a preferred design, the X-axis mounting plate 201 is provided with three fixing structures 211, and the Z-axis slide rail 204 and pressure head 4 are each provided with three.

[0030] In this embodiment, see Figure 1 , Figure 2As a preferred design, the main cylinder 302 of the drive mechanism 3 is also provided with multiple magnetic switches for detecting the moving position of the main cylinder 302. The multiple magnetic switches can detect the position of the piston of the main cylinder 302, that is, the position of the X-direction mounting plate 201. Preferably, the main cylinder 302 is provided with three magnetic switches. When the three pressure heads 4 are respectively located in the spacer 102 and are slidably connected with the pressure head connecting seat 105 in the spacer 102, the three pressure heads 4 are respectively provided with three magnetic switches at their respective positions relative to the main cylinder 302.

[0031] In this embodiment, see Figure 1 , Figure 2 As a preferred design, the X-direction mounting plate 201 and the Z-direction mounting plate 202 are integrally formed. Specifically, the X-direction mounting plate 201 and the Z-direction mounting plate 202 are integrally formed into an L-shaped mounting plate, which can significantly improve its structural strength and stability, reduce the number of parts, and reduce the overall cost.

[0032] In this embodiment, see Figure 1 As a preferred design, the bottom end of the pressure head connecting seat 105 is provided with a T-shaped groove, and the top end of the pressure head 4 is provided with a T-shaped boss that matches the T-shaped groove. The pressure head 4 is slidably connected in the T-shaped groove of the pressure head connecting seat 105 through the T-shaped boss. By setting the T-shaped groove and the T-shaped boss, precise positioning can be achieved, and relative displacement between the pressure head connecting seat 105 and the pressure head 4 can be avoided.

[0033] As can be seen from the above, the automatic pressure head switching pressing device of this utility model has the following beneficial effects:

[0034] By configuring the frame body 1, moving mechanism 2, drive mechanism 4, pressure head 4, and positioning mechanism 5, and employing a dual-cylinder drive system, multi-process composite pressing can be completed during the pressing process. The entire process of switching pressure head 4 is fully automated without manual intervention, resulting in high assembly efficiency. Furthermore, the total cost of the moving mechanism 2 and positioning mechanism 5 is approximately 50% of that of traditional servo-driven pressure head switching mechanisms, and maintenance costs are low, meeting the requirements of enterprises for cost reduction and efficiency improvement.

[0035] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
