Description

Technical Field

[0001] This utility model relates to the field of guide press-fitting technology, specifically to a guide press-fitting device for automotive shock absorbers. Background Technology

[0002] The guide is one of the important components in the automotive shock absorber. It plays a good guiding role in the movement of the piston rod in the shock absorber, ensuring the smoothness of the piston during operation. At the same time, during the piston movement, the oil hole of the guide connects the working cylinder and the oil reservoir.

[0003] Chinese Patent Publication No. CN220278799U discloses "A Press-fitting Equipment for an Automobile Shock Absorber Guide", which includes a worktable. A hydraulic mechanism is fixedly installed on the top of the worktable, and a pressure head is fixedly installed at the output end of the hydraulic mechanism. A main component positioning assembly is fixedly installed on the top of the main component positioning assembly, and a press-fitting component positioning assembly is installed on the top of the main component positioning assembly. Support legs are fixedly connected to both sides of the press-fitting component positioning assembly. The two support legs are fixedly installed on the top of the worktable. The guide body is placed inside the main component positioning assembly. This utility model can position the guide body and the guide sleeve press-fitting component separately by setting the main component positioning assembly and the press-fitting component positioning assembly, so that the guide body and the guide sleeve press-fitting component can be accurately aligned along the vertical central axis, replacing the manual alignment method of the guide body and the guide sleeve press-fitting component, which is beneficial to improving processing efficiency.

[0004] While existing technologies facilitate alignment, small parts such as guides and gaskets that fall during pressing may scatter inside the equipment or on the ground, leading to material waste. If the material mixes with oil or impurities in the equipment, it may contaminate subsequent pressing batches, increasing quality risks. Furthermore, after pressing, the material may become stuck in the pressing chamber due to excessive friction or pressing force, requiring manual knocking or prying to remove it, which is extremely inefficient. Improper force during manual demolding may also cause material deformation or damage. Utility Model Content

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, when it is necessary to remove the material from the press box, the present invention uses a rotary motor to rotate a bidirectional threaded rod. The bidirectional threaded rod moves the threaded blocks with threaded sleeves. Since the bidirectional threaded rod is a bidirectional lead screw, the threaded blocks on both sides move in the center when the bidirectional threaded rod rotates. The movement of the threaded blocks pushes the sliding plate inside the fixed frame through the lifting plate. The sliding of the sliding plate drives the lifting rod to push the material out of the press box. Through the above technical solution, the material damage or deformation caused by manual forcible removal is prevented, and the material is directly pushed out, reducing the time for manual material removal.

[0016] Secondly, when it is necessary to remove the material from the press box, the present invention uses a rotary motor to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the threaded blocks with threaded sleeves to move. Since the bidirectional threaded rod is a bidirectional lead screw, the threaded blocks on both sides move in the center when the bidirectional threaded rod rotates. The movement of the threaded blocks pushes the sliding plate inside the fixed frame through the lifting plate. The sliding of the sliding plate drives the lifting rod to push the material out of the press box. Through the above technical solution, the material damage or deformation caused by manual forced removal is prevented, and the material is directly pushed out, reducing the time for manual material removal.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 A pressure fitting device for automotive shock absorber guides includes a workbench 1, a lifting assembly at the bottom of the workbench 1, and a receiving assembly at the top of the workbench 1.

[0023] The lifting assembly includes a fixed frame 3, and a bidirectional threaded rod 301 is rotatably embedded inside the fixed frame 3. Multiple threaded blocks 303 are threaded on the outer surface of the bidirectional threaded rod 301. A sliding plate 4 is slidably embedded inside the fixed frame 3, and a lifting rod 5 is fixedly connected to the top of the outer surface of the sliding plate 4. A pressing box 101 is fixedly connected to the top of the outer surface of the workbench 1, and the lifting rod 5 is slidably embedded inside the pressing box 101.

[0024] The receiving component includes a pressing mechanism 2, and a movable frame 6 is fixedly connected to one side of the outer surface of the pressing mechanism 2. A first connecting column 601 is rotatably embedded inside the movable frame 6, and a first transmission plate 602 is rotatably sleeved on the outer surface of the first connecting column 601. A pressing head 201 is fixedly connected to the bottom of the outer surface of the pressing mechanism 2, and multiple fixed plates 610 are fixedly connected to the top of the outer surface of the workbench 1.

[0025] With the above technical solution, when it is necessary to remove the material inside the pressing box 101, the rotary motor 304 is turned on, which drives the bidirectional threaded rod 301 to rotate. The bidirectional threaded rod 301 drives the threaded block 303 with threaded sleeve to move. Since the bidirectional threaded rod 301 is a bidirectional lead screw, when the bidirectional threaded rod 301 rotates, the threaded blocks 303 on both sides move in the center. The movement of the threaded blocks 303 pushes the slide plate 4 to slide inside the fixed frame 3 through the lifting plate 403. The sliding of the slide plate 4 drives the lifting rod 5 to push the material inside the pressing box 101 out. With the above technical solution, the material damage or deformation caused by manual forced removal is prevented, and the material is directly pushed out, reducing the time for manual material removal.

[0026] Through the above technical solution, when the pressing mechanism 2 moves downward, it drives the moving frame 6 downward. When the moving frame 6 moves downward, it drives the first transmission plate 602 to rotate around the sixth connecting column 611. The movement of the first transmission plate 602 drives the second transmission plate 604 and the third transmission plate 606 to move, and then the fourth transmission plate 608 rotates around the sixth connecting column 611. The movement of the first transmission plate 602 and the fourth transmission plate 608 drives the third transmission plate 606 and the second transmission plate 604 to move backward, and then drives the fixed arm 7 to move backward, thereby preventing the pressing mechanism 2 from hitting the receiving plate 8. Similarly, when the pressing mechanism 2 is lifted upward, the receiving plate 8 is reset, thereby receiving the material inside the pressing head 201. Through the above technical solution, material is prevented from falling into the equipment or onto the ground, avoiding impact on subsequent production, reducing material loss, eliminating the need for frequent manual cleaning of fallen material, and improving production efficiency.

[0027] Specifically, a plurality of fixing blocks 401 are fixedly connected to the top of the outer surface of the slide plate 4, and a first connecting rod 402 is rotatably embedded inside the plurality of fixing blocks 401. A lifting plate 403 is rotatably sleeved on the outer surface of the plurality of first connecting rods 402, and a second connecting rod 404 is rotatably embedded inside the plurality of threaded blocks 303. The plurality of second connecting rods 404 are rotatably embedded inside the lifting plate 403.

[0028] Through the above technical solution, the threaded block 303 moves through the lifting plate 403, thereby pushing the slide plate 4 to slide inside the fixed frame 3.

[0029] Specifically, a limiting rod 302 is fixedly connected to one side of the outer surface of the fixing frame 3, and multiple threaded blocks 303 are slidably sleeved on the outer surface of the limiting rod 302.

[0030] The above technical solution limits the threaded block 303 by means of the limiting rod 302.

[0031] Specifically, the second connecting post 603 is rotatably embedded inside the first transmission plate 602, and the second transmission plate 604 is rotatably sleeved on the outer surface of the second connecting post 603. The third connecting post 605 is rotatably embedded inside the second transmission plate 604, and the third transmission plate 606 is rotatably sleeved on the outer surface of the third connecting post 605. The fourth connecting post 607 is rotatably embedded inside the third transmission plate 606, and the fourth transmission plate 608 is rotatably sleeved on the outer surface of the fourth connecting post 607. The fifth connecting post 609 is rotatably embedded inside the fourth transmission plate 608, and the fifth connecting post 609 is rotatably embedded inside the fixed plate 610.

[0032] Through the above technical solution, when the moving frame 6 moves downward, it drives the first transmission plate 602 to rotate around the sixth connecting column 611. The movement of the first transmission plate 602 drives the movement of the second transmission plate 604 and the third transmission plate 606, which in turn causes the fourth transmission plate 608 to rotate around the sixth connecting column 611. The movement of the first transmission plate 602 and the fourth transmission plate 608 drives the third transmission plate 606 and the second transmission plate 604 to move backward.

[0033] Specifically, a fixed arm 7 is rotatably sleeved on the outer surface of the third connecting post 605, and a sliding groove 701 is provided inside the fixed arm 7. A sixth connecting post 611 is rotatably embedded inside the first transmission plate 602, and the side of the sixth connecting post 611 away from the first transmission plate 602 is rotatably embedded inside the fourth transmission plate 608. The sixth connecting post 611 is slidably embedded inside the sliding groove 701. A receiving plate 8 is fixedly connected to one side of the outer surface of the fixed arm 7.

[0034] With the above technical solution, when the pressing mechanism 2 moves downward, the fixed arm 7 moves backward, and when the pressing mechanism 2 is lifted upward, the receiving plate 8 is reset, thereby receiving the material inside the pressing head 201.

[0035] Specifically, a motor plate 305 is fixedly connected to one side of the outer surface of the fixed frame 3, and a rotary motor 304 is provided on the top of the outer surface of the motor plate 305. The output shaft of the rotary motor 304 is fixedly connected to the bidirectional threaded rod 301.

[0036] With the above technical solution, when the pressing mechanism 2 is lifted upward, the receiving plate 8 is reset, thereby receiving the material inside the pressing head 201.

[0037] In use, when it is necessary to remove the material from inside the pressing box 101, the rotary motor 304 is turned on, which drives the bidirectional threaded rod 301 to rotate. The bidirectional threaded rod 301 drives the threaded block 303 with threaded sleeve to move. Because the bidirectional threaded rod 301 is a bidirectional lead screw, when the bidirectional threaded rod 301 rotates, the threaded blocks 303 on both sides move in the center. The movement of the threaded blocks 303 pushes the sliding plate 4 inside the fixed frame 3 through the lifting plate 403. The sliding of the sliding plate 4 drives the lifting rod 5 to push the material out of the pressing box 101. Through the above technical solution, the material damage or deformation caused by manual forced removal is prevented. The material is directly pushed out, reducing the time for manual material removal. When the pressing mechanism 2 moves downward, it drives the moving frame 6 downward. During operation, the first transmission plate 602 rotates around the sixth connecting column 611. This rotation of the first transmission plate 602 then drives the second transmission plate 604 and the third transmission plate 606, which in turn causes the fourth transmission plate 608 to rotate around the sixth connecting column 611. The movement of the first and fourth transmission plates 602 and 608 then moves the third transmission plate 606 and the second transmission plate 604 backward, which in turn moves the fixed arm 7 backward. This prevents the pressing mechanism 2 from colliding with the receiving plate 8. Similarly, when the pressing mechanism 2 is lifted upward, the receiving plate 8 resets, thus receiving the material inside the pressing head 201. This technical solution prevents material from falling into the equipment or onto the ground, avoiding impact on subsequent production, reducing material loss, eliminating the need for frequent manual cleaning of fallen material, and improving production efficiency.
