Hydraulic drive guide mechanism

Abstract

The utility model provides a hydraulic drive guide mechanism, relates to the field of guide accessories, and aims to solve the problem that the existing hydraulic drive guide mechanism is easy to loosen again after being used for many times due to the fact that the clamping force is in a constant state during clamping. The main body is of a cylindrical structure, the stress rods are of T-shaped structures, the outer sides of the stress rods are of inclined structures, the number of the stress rods is two, and the stress rods are made of metal materials. When the main body operates, the driving rod and the positioning plate move outwards together, the stress rod can control the front end of the driving rod to conduct guiding displacement while the driving rod and the positioning plate move outwards, and during displacement, due to the fact that the outer side of the stress rod is of an inclined structure, the stress rod is driven to move together, and meanwhile the outer side of the stress rod makes sliding contact with the inner side of the pushing head. And the stress rod is pushed to move inwards, so that the inner part clamps the outer end of the driving rod, the probability of loosening after long-time use is avoided, and the pushing stability is improved.

After adjusting the position, the clamping block can be engaged with the wedge rod inside the external part, so that the control part can be firmly fixed to avoid looseness, so that when the force-bearing rod is displaced again, the clamping force can be increased.

The rod 102 becomes loose, and there are two force-bearing rods 108, which are made of metal; the side piece 2 is a rectangular structure, and the side piece 2 is made of metal. There are two side pieces 2, and the two side pieces 2 are respectively located on both sides of the main body 1. An outer piece 203 is installed on the front end of each side piece 2, and a control piece 206 is installed inside each outer piece 203. The control piece 206 is a U-shaped structure, which can be easily pulled and displaced, thereby driving the block 208 to move together. The control piece 206 is made of metal, and each control piece 206 is provided with evenly arranged blocks 208 on the outside. The block 208 is a wedge-shaped structure, which is used to be clamped with the wedge block inside the outer piece 203, so that after the control piece 206 is adjusted, it can be automatically limited and fixed.

[0023] refer to Figure 4Four positioning members 101 are respectively provided at the upper and lower ends of the main body 1, and every two positioning members 101 are symmetrically arranged. The two ends of the positioning members 101 are wedge-shaped structures, which are used to guide the fixing member 204 to be embedded, so that the fixing member 204 can drive the side member 2 to be firmly installed and used. The positioning member 101 is made of metal, and the driving rod 102 is a cylindrical structure. The driving rod 102 is a retractable structure, which can be conveniently retracted and pushed; the outer end of the driving rod 102 is provided with two positioning plates 103, and the positioning plates 103 are annular structures, which are used to guide the inner member 105 to be embedded and clamped, and the two ends of the two positioning plates 103 are respectively provided with a guide member 104, the guide member 104 is a rectangular structure, and the interior of the guide member 104 is a cross-shaped structure, which is used to allow the push plate 106 and the connecting plate 107 to move inside it; an inner member 105 is embedded at both ends of the two positioning plates 103, and the inner member 105 is an arc-shaped structure, which is used to clamp the driving rod 102. The inner member 105 is made of metal, and a push plate 106 is provided at the outer end of each inner member 105. The push plate 106 is a rectangular structure, which can be pushed to move the inner member 105 by force. The push plate 106 is embedded in the interior of the guide member 104, and a connecting plate 107 is fixed to the side of each push plate 106.

[0024] refer to Figure 5 Each side member 2 is provided with an inner groove 201, which is a T-shaped structure and is used to guide the displacement of the force-bearing rod 108 therein. A through groove 202 is provided inside the front end of each side member 2, and the through groove 202 is a rectangular structure and is used to guide the movement of the push head 205; the outer member 203 is a rectangular structure, and the interior of the outer member 203 is a cross-shaped structure and is used to guide the displacement of the control member 206 therein. A wedge-shaped rod is provided on the inner side of the outer member 203 and is used to be clamped and fixed with the clamping block 208. The control member 206 is inserted into the inner side of the outer member 203. Two fixing members 204 are provided at both ends of the inner side of each side member 2, and the fixing members 204 are arc-shaped structures. Every two fixing members 204 are fixed and installed by bolts. 04 is fixed on the outside of the main body 1 to be firmly fixed on the outside of the main body 1; a pushing head 205 is inserted into the inside of each through groove 202, and the pushing head 205 is made of metal. The inner and outer sides of the pushing head 205 are inclined structures. The inner side of the pushing head 205 contacts the outer side of the force-bearing rod 108, which can push the force-bearing rod 108 to move, so that the force-bearing rod 108 can clamp the driving rod 102 under force to avoid loosening. A top piece 207 is provided on the inner side of each control member 206, and the top piece 207 is a wedge-shaped structure. The inner side of the top piece 207 contacts the outer side of the pushing head 205, so that the top piece 207 can push the pushing head 205, so that the pushing head 205 can adjust the position of the force-bearing rod 108, thereby increasing the clamping force.

[0025] When using: When the device is needed, the main body 1 can be assembled by human control first, so that when the main body 1 is in use, when the driving rod 102 moves outward, the inner part 105 can be driven to move together, so that the inner part 105 can drive the pushing plate 106 and the connecting plate 107 to move together, so that the force rod 108 can be moved and displaced. Since the outer side of the force rod 108 is an inclined structure, it can be inclined with the inner side of the pushing head 205, so that the force rod 108 can be pushed and displaced, and then the inner part 105 can move inside the positioning plate 103, thereby improving the force on the driving rod 102. The holding effect is achieved to prevent the driving rod 102 from loosening. If the driving rod 102 is loose or the clamping force needs to be adjusted, the control member 206 can be directly pulled to move together, so that the clamping block 208 can pass through the wedge block and can be easily fixed after moving. When the clamping block 208 moves, the top member 207 is driven to move together, so that the top member 207 can slide in contact with the outer end of the pushing head 205, so that the pushing head 205 can move inward, thereby adjusting the force displacement of the force-bearing rod 108, and then after the force-bearing rod 108 moves again, the clamping force can be further adjusted to avoid loosening and improve the guiding effect.
