AI Technical Summary
When the existing dual-guide rod cylinder direct propulsion and retraction mechanism is strong, it directly contacts the cylinder push rod, which may cause damage to the cylinder and affect the service life of the cylinder.
A wedge-shaped slider stop device is designed, including a mounting frame, a cylinder, a positioning block, a wedge block, a guide plate, a connecting screw and an elastic member. When the wedge block is pushed upward by the cylinder, the positioning block slides in the first direction. When the cylinder drives the wedge block to move downward, the positioning block slides in the second direction to the working position, so that the force acts on the wedge block.
By setting the wedge block, the force acts on the wedge block with a larger incline, avoiding the impact on the cylinder and extending the service life of the cylinder.

[0024] Example
[0025] The currently commonly used double-guide-rod cylinder directly pushes and retracts the mechanism. When the applied force is large, it directly contacts the cylinder push rod, which may cause damage to the cylinder and affect the service life of the cylinder.
[0026] In order to solve the above technical problems, refer to Figure 1 and Figure 2As shown, this embodiment provides a wedge-shaped slider stopper device including a mounting frame 1, a cylinder 2, a positioning block 4, a wedge block 7, a guide plate 5, a connecting screw 12 and an elastic member 11. The cylinder 2 is mounted on the mounting frame 1. The positioning block 4 is slidably mounted on the mounting frame 1 and is located above the cylinder 2. The wedge block 7 is slidably mounted on the mounting frame 1 and is connected to the cylinder 2. The positioning block 4 abuts against the side of the wedge block 7. The guide plate 5 is mounted on the mounting frame 1 and abuts against the side of the wedge block 7. One end of the connecting screw 12 passes through the wedge block 7 and is connected to the positioning block 4, and the other end is located outside the wedge block 7. The elastic member 11 is sleeved on the connecting screw 12, one end of the elastic member 11 is located on one end of the connecting screw 12 located outside the wedge block 7, and the other end abuts against the positioning block 4. There are two guide plates 5, which are respectively located on both sides of the wedge block 7.
[0027] Through the above structure, the present embodiment provides a wedge-shaped slider stop device. When the cylinder 2 pushes the wedge block 7 to move upward, the positioning block 4 slides along the first direction. When the cylinder 2 drives the wedge block 7 to move downward, the positioning block 4 slides along the second direction to the working position, so that the force acts on the wedge block 7. It should be specifically noted that the first direction refers to Figure 2 The direction indicated by the arrow A in the middle, the second direction refers to Figure 2 In the direction indicated by arrow B.
[0028] On the basis of the above, refer to Figure 2 The wedge-shaped slider stop device further comprises a support frame 3. The support frame 3 is mounted on the mounting frame 1, the wedge block 7 and the positioning block 4 are slidably mounted on the support frame 1, and the guide plate 5 is mounted on the support frame 3.
[0029] On the basis of the above, refer to Figure 2 As shown, a wedge-shaped slider stop device also includes a connecting plate 6. The connecting plate 6 is installed on the support frame 3, and the connecting plate 6 is located between the positioning block 4 and the wedge block 7. The two sides of the connecting plate 6 are respectively in contact with the positioning block 4 and the wedge block 7, and one end of the elastic member 11 located in the wedge block 7 is connected to the connecting plate 6. When the wedge block 7 is pushed upward by the cylinder 2, the connecting plate 6 drives the positioning block 4 to slide in the first direction. When the cylinder 2 drives the wedge block 7 to move downward, the connecting plate 6 drives the positioning block 4 to slide in the second direction to the working position, so that the force acts on the wedge block 7.
[0030] On the basis of the above, refer to Figure 3 and Figure 4As shown, a wedge-shaped slider stopper also includes a fixing plate 8. The fixing plate 8 is mounted on the support frame 3 and is located on a side of the wedge block 7 away from the connecting plate 6, and the connecting screw 12 passes through the fixing plate 8.
[0031] On the basis of the above, refer to Figure 4 As shown, a wedge-shaped slider stopper also includes a transition rod 10. One end of the transition rod 10 is mounted on the cylinder 2, and the other end is fixed to the wedge block 7 by a fastening bolt 9. Thus, the cylinder 2 drives the wedge block 7 to slide.
[0032] On the basis of the above, refer to Figure 4 As shown, in order to facilitate the sliding of the wedge block 7, a U-shaped groove is opened inside the wedge block 7, and the connecting screw 12 is located in the U-shaped groove.
[0033] In summary, during the use of a wedge-shaped slider stopper, first, the cylinder 2 is pushed upward by ventilation, the wedge block 7 is connected to the cylinder push rod by the fastening bolts 9 and the transition rod 10, the wedge block 7 also moves upward, the two side surfaces of the wedge block 7 cooperate with the inclined surfaces of the connecting plate 6 and the fixing plate 8, the positioning block 4 and the connecting plate 6 move in the first direction under the pulling force of the elastic member 11, and separate from the components to be positioned; when the cylinder 2 is ventilated and retracted downward, the wedge block 7 pushes the positioning block 4 and the connecting plate 6 to move in the second direction until they fit with the support frame 3; when the applied force is large, the wedge block 7 generates a downward component force to limit the movement of the positioning block 4, thereby preventing damage to the cylinder 2. The technical problem that the existing double-guide rod cylinder direct push-back mechanism directly contacts the cylinder push rod when the applied force is large, which may cause damage to the cylinder and affect the service life of the cylinder is solved.
[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
