A pneumatic-hydraulic booster cylinder and a fixing seat for fixing the roller workpiece are respectively provided on both sides of the ends of the first and second storage seats. The pressure head of the pneumatic-hydraulic booster cylinder is arranged facing the ends of the first and second storage seats and coaxially with the roller workpiece. The ends of the first and second storage seats facing the pressure head are respectively provided with a first slot and a second slot for the pressure head to pass through. The first and second storage seats are coaxial with the pressure head and can move up and down at one end. The first and second storage seats can hold multiple inserts in batches and automatically fill them into the first and second slots. The pneumatic-hydraulic booster cylinder can press the inserts in the first and second slots to the inside of the roller workpiece to achieve automatic pressing. The up-and-down movement of the ends of the first and second storage seats can make way for the pressing of different inserts and ensure the stability of the pressing of the inserts and the roller workpiece. The above structure effectively improves the pressing efficiency of batch pressing of multiple inserts and eliminates the need for frequent manual feeding, effectively reducing the danger of manual feeding.

[0007] Preferably, the top surfaces of the first and second storage seats are respectively provided with a first storage groove and a second storage groove for sequentially placing inserts and cooperating with the sides of the inserts. The first and second storage seats are both inclined downward toward the end where the first and second slots are located.

[0008] Preferably, the workbench surface is provided with a base plate, and the outer side of the base plate is connected to an extension frame that is rotatably connected to the top of the first and second storage seats and is inclined; the base plate and the extension frame can support the first and second storage seats and raise the ends of the first and second storage seats through the extension frame, so that the first discharge trough and the second storage trough are inclined, so that the insert can be automatically replenished with material along the inclination.

[0009] Preferably, the first and second storage seats have openings on the worktable below the end near the pressure head. The bottom of the worktable is provided with a first driving cylinder and a second driving cylinder for driving the first and second storage seats to move up and down respectively. The output ends of the first and second driving cylinders are rotatably connected to the bottom of the first and second storage seats respectively, and the other ends of the first and second driving cylinders are rotatably connected to the vertical plate at the bottom of the worktable. The openings allow the first and second driving cylinders to pass through the openings and connect to the first and second storage seats, so as to control the rotation of the first and second storage seats, thereby driving the first and second storage seats to move up and down respectively and maintaining the tilted state of the first and second storage seats.

[0010] Preferably, the pressure head includes a first mating portion and a second mating portion that mate with the inner ring of inserts of different sizes, and a first pressing surface and a second pressing surface for pressing inserts of different sizes; the above-mentioned first mating portion and second mating portion enable the pressure head to adapt to inserts of different sizes, so that different inserts can be pressed through different first pressing surfaces and second pressing surfaces, so as to press different inserts simultaneously and improve the pressing efficiency of roller workpieces.

[0011] Preferably, the workbench surface is provided with a mounting bracket for fixing the gas-hydraulic booster cylinder. The output shaft of the gas-hydraulic booster cylinder passes through the mounting bracket and connects to the pressure head. The bottom side of the mounting bracket is provided with a first extension section, and the angle between the inner side of the first extension section and the side wall of the mounting bracket matches the angle between the first extension section and the base plate. The mounting bracket can fix the gas-hydraulic booster cylinder, so that the gas-hydraulic booster cylinder can stably drive the pressure head. The first extension section can be used to position the mounting bracket and the gas-hydraulic booster cylinder by cooperating with the base plate, so that the pressure head and the roller workpiece are kept coaxial, making the assembly of the mounting bracket simpler and the position more accurate.

[0013] Preferably, a vertically arranged stabilizing plate is provided between the support plate and the second storage seat. The top of the stabilizing plate is provided with an arc-shaped groove that matches the arc surface of one end of the roller workpiece. The other side of the support plate is provided with a vertically arranged top plate that abuts against the end of the roller workpiece. The top plate is fixed on a connecting frame fixed to the worktable. The stabilizing plate can enhance the support stability of the roller workpiece through the arc-shaped groove, ensuring the stability of the roller workpiece during pressing. The top plate can limit the end of the roller workpiece, increasing the axial support force of the roller workpiece for the pressing head, so that the pressing head can maintain the stability of the axial position during pressing.

[0019] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] like Figure 1As shown, a pressing device for roller workpieces and inserts includes a worktable 1. Above the worktable 1 are a first storage seat 21 and a second storage seat 22, arranged parallel to each other for placing inserts. At the ends of the first storage seat 21 and the second storage seat 22 are respectively provided a pneumatic-hydraulic booster cylinder 3 and a fixing seat 4 for fixing the roller workpiece. The pressure head 31 of the pneumatic-hydraulic booster cylinder 3 is positioned towards the ends of the first storage seat 21 and the second storage seat 22 and is coaxial with the roller workpiece. The ends of the first storage seat 21 and the second storage seat 22 face... A first slot 211 and a second slot 221 are respectively provided on one side of the pressure head 31 for the pressure head 31 to pass through. The first storage seat 21 and the second storage seat 22 are coaxial with the pressure head 31 and can move up and down. The top surfaces of the first storage seat 21 and the second storage seat 22 are respectively provided with a first storage groove 212 and a second storage groove 222 for sequentially placing the insert and cooperating with the side of the insert. The first storage seat 21 and the second storage seat 22 are both inclined downward toward the end where the first slot 211 and the second slot 221 are located.

[0021] The aforementioned gas-hydraulic booster cylinder is a product already available on the market and is existing technology, so it will not be described in detail here. In this embodiment, the embedded component includes a metallurgical block stored in the first storage tank and a gear ring stored in the second storage tank. The embedded component automatically stops at the first and second slots. The pressure head of the gas-hydraulic booster cylinder is located at the first and second slots. When the first and second slots are filled with the embedded component, the gas-hydraulic booster cylinder starts, driving the pressure head to move towards the first slot until the embedded component is fitted onto the pressure head. Subsequently, the first and second storage tanks move down to make room, and the gas-hydraulic booster cylinder drives the pressure head, carrying the embedded component towards... The stepped surface of the inner ring of the roller workpiece moves and presses the insert onto the inner ring of the roller workpiece. Then, the pneumatic-hydraulic booster cylinder drives the press to move out of the roller workpiece and controls the second storage seat to move upward. Subsequently, the press head moves towards the second slot until the insert is fitted onto the press head. Then, the second storage seat moves downward to make room. The pneumatic-hydraulic booster cylinder drives the press head to move with the insert towards the stepped surface of the inner ring of the roller workpiece and presses the insert onto the inner ring of the roller workpiece. Finally, the press head leaves the roller workpiece and returns to its original position. The first and second storage seats move upward to their original positions. At this time, the subsequent inserts automatically roll to the first and second slots to start a new pressing process.

[0022] like Figure 2As shown, a base plate 2 is provided on the workbench 1. An extension frame 23 is connected to the outside of the base plate 2 and is rotatably connected to the top of the first storage seat 21 and the second storage seat 22 and is inclined. An opening 11 is provided on the workbench 1 below the end of the first storage seat 21 and the second storage seat 22 near the pressure head 31. A first driving cylinder 12 and a second driving cylinder 13 are provided at the bottom of the workbench 1 for driving the first storage seat 21 and the second storage seat 22 to move up and down respectively. The output ends of the first driving cylinder 12 and the second driving cylinder 13 are rotatably connected to the bottom of the first storage seat 21 and the second storage seat 22 respectively. The other ends of the first driving cylinder 12 and the second driving cylinder 13 are rotatably connected to the vertical plate 14 at the bottom of the workbench 1.

[0023] One end of the first and second storage seats is rotatably connected to the outer end of the extension frame, while the other end of the first and second storage seats is located at the pressure head and can move up and down. The output shafts of the first and second drive cylinders both pass through the opening and are rotatably connected to the ends of the first and second storage seats. When the first or second storage seat needs to move, the first and second drive cylinders are started independently to control one end of the first and second storage seats to move automatically.

[0024] like Figure 3 As shown, the pressure head 31 includes a first mating part 311 and a second mating part 312 that mate with the inner ring of inserts of different sizes, and a first pressing surface 313 and a second pressing surface 314 for pressing inserts of different sizes. The outermost end of the pressure head is the first mating part and the first pressing surface formed on the end face of the second mating part. The stepped surface of the second mating part forms the second pressing surface, which can abut against and press the inserts respectively. The first mating part and the second mating part of the pressure head are fixed to the inner ring of the inserts. The inserts are sleeved on the first mating part and the second mating part. The first pressing surface and the second pressing surface contact the end face of the inserts and press the inserts to form a pressing on the inserts.

[0025] like Figure 1-2As shown, the workbench 1 has a mounting bracket 15 for fixing the gas-hydraulic booster cylinder 3. The output shaft of the gas-hydraulic booster cylinder 3 passes through the mounting bracket 15 and is connected to the pressure head 31. The bottom side of the mounting bracket 15 has a first extension section 151. The angle between the first extension section 151 and the side wall of the mounting bracket 15 matches the angle between the first extension section 151 and the side wall of the base plate 2. The mounting base 4 includes a mounting plate 41 on the workbench 1 and a support plate 42 on the mounting plate 41 and arranged vertically. The top of the support plate 42 has a V-shaped support for placing the roller workpiece. The bottom plate 2 has a second extension section 24 on its side, and the angle between the second extension section 24 and the side wall of the bottom plate 2 matches the angle between the side wall of the fixing plate 41. A vertically arranged stabilizing plate 43 is provided between the support plate 42 and the second storage seat 22. The top of the stabilizing plate 43 is provided with an arc groove 431 that matches the arc surface of one end side wall of the roller workpiece. The other side of the support plate 42 is provided with a top plate 44 that abuts against the end of the roller workpiece and is vertically arranged. The top plate 44 is fixed on the connecting frame 45 fixed to the worktable 1.

[0026] The aforementioned fixing frame is fitted to the side of the base plate via the first extension section, and the base plate is fitted to the side of the fixing plate via the second extension section. The three are mutually positioned and fitted to maintain a stable coaxial position for the roller workpiece, the insert, and the pressure head. After the roller workpiece is placed in the V-groove of the support plate, one end of the roller workpiece is stuck in the arc-shaped groove of the stabilizing plate, the side wall of the roller workpiece abuts against the V-groove of the support plate, and the other end of the roller workpiece rests on the end face of the top plate. The top plate is fixed to the worktable via the connecting frame to maintain a vertical state and to limit the axial movement of the roller workpiece.

[0027] like Figure 1-2 As shown, both the base plate 2 and the fixing plate 41 are fixed to the worktable 1 by multiple quick-press clamps 16 fixed to the worktable 1. The aforementioned quick-press clamps are products currently available on the market. They are fixed to the worktable by bolts and press the sides of the base plate and the fixing plate onto the worktable, which facilitates subsequent replacement and maintenance.
