Description

Technical Field

[0001] This utility model relates to the field of press-fitting equipment, and in particular to a top-pressing mechanism for press-fitting equipment. Background Technology

[0002] Press-fitting equipment is widely used in the installation of bearings, oil seals, and other components in various products. During press-fitting, the bearings and other components are pressed into the product by bringing the pressing components located at the top and bottom of the product closer together. Since the types, quantities, sizes, and specifications of the components requiring press-fitting vary for each product, existing solutions typically involve manufacturing corresponding tooling plates and press head assemblies for each product requiring press-fitting, and combining the tooling plates and press heads into a single structure. During press-fitting, different tooling plate-press head combinations are selected based on the product, and assembled using the same press-fitting equipment. However, due to the large number of product models used for press-fitting, a large number of combined structures are generated. This is inconvenient for quick retrieval and use, and the combined structures require significant storage space, resulting in high costs for space, equipment, and labor management.

[0004] Based on the above scheme, the first pressure rod includes a first pressure block, a first pressing post, and a first return spring. The first pressure block and the first pressing post are fixedly connected axially. The first pressure block is disposed at the upper end of the first pressing post, and the outer edge of the first pressure block protrudes radially outward from the outer side of the first pressing post.

[0007] Preferably, the first connecting part is provided with a snap-fit ​​groove, a positioning hole and a positioning pin. The snap-fit ​​groove is located at the bottom of the first pressing post and is formed by a recess along the axial direction. The positioning hole is located at the lower part of the first pressing post and is a through hole arranged radially along the first pressing post. The positioning hole communicates with the snap-fit ​​groove, and the positioning pin is detachably inserted into the positioning hole.

[0008] Preferably, it also includes a tooling movement mechanism for driving the tooling plate to move in the horizontal plane.

[0009] Based on the above scheme, the tooling moving mechanism includes a longitudinal slide rail, a longitudinal sliding frame, a transverse slide rail, and a transverse sliding frame. The longitudinal slide rail is fixedly installed on the frame in the horizontal plane. The longitudinal sliding frame is slidably arranged on the longitudinal slide rail.

[0011] The beneficial effects of this utility model are as follows: The tooling plate and pressure bar are set separately.

The pressure head and pressure bar are detachably connected, so that the pressure bar can be used for pressing of various parts and avoid the problems of large space occupation and limited product models applicable to the tooling plate-pressure head combination structure in the prior art. Multiple pressure bars are placed on the turntables on the upper and lower sides of the product to be pressed. The position of the pressure bars is moved by rotating the turntables so that they are in the pressing position in sequence, and then the pressing operation is performed. This realizes the switching of pressure bars and saves the space occupied by multiple pressure bars. The tooling moving mechanism drives the tooling plate to move horizontally, thereby adjusting the position according to the pressing position of different products, and the pressing equipment can be adapted to press different products by changing the tooling plate. By adopting a top-to-bottom pressing method, the action and reaction forces are kept in the same direction, reducing the amount of deformation generated during the product pressing process and effectively improving the pressing accuracy. The pressure bars are installed in pairs and pressed in, which makes it easy to output and save the pressure data during the pressing process in real time. Attached Figure Description

[0016] like Figures 1 to 4As shown, a pressing and pressing mechanism for a pressing device includes a pressure rod rotation mechanism mounted on the pressing device. The pressing device includes a frame 1 and a pressing frame 75 that moves vertically relative to the frame 1. Specifically, a lifting guide rail 71 is fixedly mounted vertically on the frame 1, and a lifting slider 74 is slidably mounted on the lifting guide rail 71. The pressing frame 75 is fixedly connected to the lifting slider 74. The pressing frame 75 can be a C-shaped structure, with a tooling plate 631 for receiving the pressing product at the C-shaped opening in the middle of the pressing frame 75. The tooling plate 631 can be replaced according to different products, and a product positioning post 632 is provided on the tooling plate 631 for positioning. The upper end and lower end of the pressing frame 75 are respectively provided with an upper push rod 652 and a lower push rod 753 in the vertical direction on the side facing the tooling plate 631. The pressing method can be that the upper push rod 652 is driven by the upper press and extends downward, and the lower push rod 753 moves upward as the pressing frame moves upward, thereby realizing the pressing of the product on the tooling plate 631.

[0017] The pressure bar rotation mechanism includes a first rotation mechanism and a second rotation mechanism. The first and second rotation mechanisms are used to switch the pressure head 24 during the pressing process of the same or different products.

[0018] The first rotating mechanism is positioned above the tooling plate 631. This mechanism includes a first connecting frame 41, a first rotating drive component 42, a first turntable 43, and a first pressure rod 44. The first connecting frame 41 is fixedly mounted on the machine frame 1. The first rotating drive component 42 is positioned between the first connecting frame 41 and the first turntable 43, driving the first turntable 43 to rotate. The first rotating drive component 42 can be a motor or other power equipment. The first pressure rod 42 is mounted on the first turntable 43 and moves vertically through it. Multiple first pressure rods 44 rotate sequentially with the first turntable 43 to below the upper push rod 652. Depending on the model and specifications of the pressure head 24 connected to the first pressure rod 44, different first pressure rods 44 are selected and moved below the upper push rod 652 to be driven downwards by the upper push rod 652 for pressing.

[0019] The first pressure rod 44 includes a first pressure block 441, a first pressing post 442, and a first return spring 443. The first pressure block 441 and the first pressing post 442 are fixedly connected axially. The first pressure block 441 is located at the upper end of the first pressing post 442, and the outer edge of the first pressure block 441 protrudes radially outward from the outer side of the first pressing post 442. The first pressing post 442 passes through the first turntable 43. The bottom of the first pressing post 442 is provided with a first connecting part for connecting the pressure head. The first return spring 443 is sleeved on the outer side of the first pressing post 442, and the two ends of the first return spring 443 abut against the first pressure block 441 and the first turntable 43, respectively. When the upper push rod 752 presses the first pressure rod 44 downward, the first pressure block 441 drives the lower first pressing post 442 and the pressure head 24 to move downward for pressing. After pressing is completed, under the action of the first return spring 443, the first pressure block 441, the first pressing post 442, and the pressure head 24 move upward back to their original positions.

[0020] like Figure 4 As shown, the first connecting part is provided with a snap-fit ​​groove, a positioning hole, and a positioning pin. The snap-fit ​​groove is located at the bottom of the first pressing post 442 and is recessed upward along the axial direction. The positioning hole is located at the lower part of the first pressing post 442 and is a through hole arranged radially along the first pressing post 442, and the positioning hole communicates with the snap-fit ​​groove. The positioning pin is detachably inserted into the positioning hole. A connecting post is provided above the pressing head 24, and the connecting post is correspondingly arranged with the snap-fit ​​groove. The connecting post is provided with a radial through hole. When installing the pressing head 24, the connecting post is snapped into the snap-fit ​​groove, so that the connecting post is aligned with the through hole on the first pressing post 442. Then, the positioning pin is simultaneously inserted into the through holes of the two parts to complete the quick installation of the pressing head 24. When disassembling, the positioning pin and the pressing head connecting post are pulled out in sequence, thereby realizing the convenient and detachable connection of the pressing head 24.

The second rotating mechanism includes a second connecting frame 51, a second rotating drive component 52, a second turntable 53, and a second pressure rod 54.

The second rotating drive component 52 can be a motor or other power equipment. The second pressure rod 54 is mounted on the second turntable 53 and moves vertically through the second turntable 53. There are multiple second pressure rods 54, which rotate sequentially with the second turntable 53 to above the lower push rod 753. Depending on the model and specifications of the pressure head 24 connected to the second pressure rod 54, different second pressure rods 54 are selected to move above the lower push rod 753, so that they are driven by the lower push rod 753 to move upwards and perform pressing.

[0022] The second pressure rod 54 includes a second pressure block 541 and a second pressing post 542. The second pressure block 541 and the second pressing post 542 are fixedly connected axially. The second pressure block 541 is located at the lower end of the second pressing post 542, and the outer edge of the second pressure block 541 protrudes radially outward from the outer edge of the second pressing post 542. The second pressing post 442 passes through the second turntable 43, and a second connecting part for connecting the pressure head is provided at the top of the second pressing post 442. When the lower push rod 753 presses the second pressure rod 54 upward, the second pressure block 541 drives the second pressing post 542 and the pressure head 24 to move upward for pressing. After pressing, under the action of gravity, the second pressure block 541, the second pressing post 542 and the pressure head 24 move downward to their original positions. The structure of the second connecting part is the same as that of the first connecting part, and the pressure head 24 and the top of the second pressing post 542 are detachably connected by a positioning pin.

[0023] A first pressure rod label 45 is provided on the first turntable 43, corresponding to the first pressure rod 44, and indicating the model number of the pressure head connected to the first pressure rod 44. A second pressure rod label 55 is provided on the second turntable 53, corresponding to the second pressure rod 54, and indicating the model number of the pressure head connected to the second pressure rod 54. This facilitates quick identification and positioning by operators and avoids installation errors.

[0026] Specifically, it also includes a longitudinal support 611, a longitudinal drive motor 612, a longitudinal slide bar 613, and a longitudinal slider 614.
