Technical Field

[0001] The utility model relates to the technical field of press-fitting machines, in particular to a press-fitting machine for dust-proof covers with uniform force. Background Art

[0002] A dust cover is an annular cover, typically stamped from thin metal sheet. It's fixed to one bearing ring or washer and extends toward the other, shielding the bearing's interior without contacting it. Currently, press-fitting dust covers is mostly performed manually, resulting in a low degree of automation, high labor intensity, and low production efficiency. Furthermore, manual operation relies entirely on the operator's feel for proper fit, making precise control of the dust cover installation process impossible. To address this issue, we have developed a dust cover press-fitting machine that delivers uniform force. Utility Model Content

[0005] In the above solution, the movable plate is provided with four matrix-arranged mounting grooves on the side wall of the through hole, and a limiting block is provided in the mounting groove. The limiting block is fixedly connected to the inner wall of the mounting groove through a spring.

[0006] In the above solution, the upper end of the limit block is provided with a slope inclined downward.

[0007] In the above solution, guide rails are provided on both sides below the movable plate, and sliders matching the guide rails are provided on the base.

[0008] In the above solution, a fixing seat is provided above the workbench and below the pressing plate.

[0009] In the above solution, a door body is provided on the side wall of the shell close to the fixing seat.

[0010] The advantages and beneficial effects of the present invention are as follows: the present invention provides a dust cover press machine with uniform force, the second hydraulic cylinder pushes the movable plate to move in the horizontal direction, so that the movable plate can move back and forth in the horizontal direction, when the through hole is below the four limit rods, the cover body inside the limit rod falls into the through hole, so that the cover body can be automatically loaded through the movable plate, the first hydraulic cylinder pushes the connecting rod to move in the vertical direction, and the pressing plate also moves with the transmission of the connecting rod, when the pressing plate presses the cover body, the cover body squeezes the limit block, the limit block enters the installation groove, and the cover body is pressed through the through hole.

[0022] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, the utility model is a dust cover press machine with uniform force, including a workbench 1, a shell 20 is provided above the workbench 1, a support frame 3 is provided in the middle above the workbench 1, a first hydraulic cylinder 4 is provided in the middle above the support frame 3, the stroke end of the first hydraulic cylinder 4 passes through the support frame 3 and is fixedly connected to the connecting rod 2, a mounting frame 5 is provided in the middle below the support frame 3, the connecting rod 2 passes through the mounting frame 5 and is fixedly connected to the pressing plate 6 away from the first hydraulic cylinder 4, and the connecting rod 2 is movably connected to the mounting frame 5. When the first hydraulic cylinder 4 is working, the first hydraulic cylinder 4 pushes the connecting rod 2 to move in the vertical direction, and the pressing plate 6 is also moved by the transmission of the connecting rod 2. A bottom is provided on one side above the workbench 1 Seat 7, a second hydraulic cylinder 8 is provided on the side above the base 7 away from the support frame 3, the stroke end of the second hydraulic cylinder 8 is fixedly connected to the movable plate 9, and a through hole 10 is provided on the side of the movable plate 9 away from the second hydraulic cylinder 8, support plates 14 are provided on both sides above the base 7, and limit rods 15 are provided on both sides above the support plates 14. The cover body to be tightened can be placed between the four limit rods 15. When the second hydraulic cylinder 8 is working, the second hydraulic cylinder 8 pushes the movable plate 9 to move in the horizontal direction, so that the movable plate 9 can move back and forth in the horizontal direction. When the through hole 10 is below the four limit rods 15, the cover body inside the limit rod 15 falls into the through hole 10, so that automatic loading of the cover body can be realized through the movable plate 9.

[0024] The movable plate 9 is located on the side wall of the through hole 10 and is provided with four mounting grooves 11 arranged in a matrix. A limit block 12 is provided in the mounting groove 11. The limit block 12 is fixedly connected to the inner wall of the mounting groove 11 by a spring 13. The limit block 12 is movably connected to the movable plate 9. The limit block 12 can move horizontally inside the movable plate 9. When the pressing disk 6 presses the cover body, the cover body squeezes the limit block 12, and the limit block 12 enters the inside of the mounting groove 11. The cover body is pressed through the through hole 10. After the cover body is pressed, the limit block 12 automatically resets under the action of the spring 13.

[0025] The upper end of the limiting block 12 is provided with an inclined surface inclined downward, and the setting of the inclined surface makes it easier for the cover to push the limiting block 12.

[0026] Guide rails 16 are provided on both sides below the movable plate 9, and sliders 17 matching the guide rails 16 are provided on the base 7. The guide rails 16 can slide on the sliders 17. Through the mutual cooperation between the guide rails 16 and the sliders 17, the movement stability of the movable plate 9 is effectively improved.

[0027] A fixing seat 18 is provided above the workbench 1 and below the pressing plate 6 , and the fixing seat 18 can position the workpiece.

[0028] The housing 20 is provided with a door 19 on a side wall close to the fixing seat 18 . The door 19 makes it easier for workers to take and place workpieces.

[0029] Specifically, in the present invention, the cover body to be compressed can be placed between the four limit rods 15. When the second hydraulic cylinder 8 is working, the second hydraulic cylinder 8 pushes the movable plate 9 to move in the horizontal direction, so that the movable plate 9 can move reciprocatingly in the horizontal direction. When the through hole 10 is below the four limit rods 15, the cover body inside the limit rod 15 falls into the through hole 10, so that the automatic loading of the cover body can be realized through the movable plate 9. When the second hydraulic cylinder 8 pushes the movable plate 9 to move so that the through hole 10 is below the pressing plate 6, the first hydraulic cylinder 4 pushes the connecting rod 2 to move in the vertical direction. Through the transmission of the connecting rod 2, the pressing plate 6 also moves accordingly. When the pressing plate 6 presses the cover body, the cover body squeezes the limit block 12, and the limit block 12 enters the inside of the installation groove 11. The cover body is pressed through the through hole 10. After the cover body is pressed, the limit block 12 is automatically reset under the action of the spring 13.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
