The existing clamping block is generally driven by an air cylinder, an electric cylinder and the like, the clamping force of the clamping oil cylinder of the clamping block is provided by the driving force of the air cylinder or the electric cylinder, the clamping force is greatly influenced by air pressure or voltage, and the clamping effect is unstable.

The application provides a hydraulic cylinder dress jar device (not shown in the figure), it includes first clamp splice (not shown in the figure), second clamp splice (not shown in the figure) and locking mechanism 1, is used for pressing from both sides tight hydro-cylinder when first clamp splice and second clamp splice are drawn close relatively, and locking mechanism 1 is used for locking first clamp splice and second clamp splice to prevent that first clamp splice and second clamp splice are not hard up, press from both sides tight effect with the promotion.

The first clamping block and the second clamping block can be driven to move manually or driven to move by driving mechanisms such as an air cylinder and an electric cylinder, after the locking mechanism 1 is locked, the first clamping block and the second clamping block are fixed in position, driving force supplied to the first clamping block and the second clamping block can be cancelled, clamping force does not need to be provided by hands or driving mechanisms such as the air cylinder and the electric cylinder, the first clamping block and the second clamping block can also keep clamping the oil cylinder, and the clamping effect is prevented from being influenced by air pressure or voltage.

Fig. 1 shows a schematic structural diagram of a locking mechanism 1, and as shown in fig. 1, the locking mechanism 1 comprises a first component 100, a second component 200, a locking component 300 and an actuating component 400, wherein the first component 100 and the second component 200 have a clamping state and an opening state, and the locking component 300 can limit the first component 100 and the second component 200 in the clamping state.

The first member 100 is connected to the first clamping block and the second member 200 is connected to the second clamping block, the first member 100 following the first clamping block and the second member 200 following the second clamping block.

It should be noted that only one of the first block and the second block may move, both of them may move, and accordingly, only one of the first member 100 and the second member 200 may move, or both of them may move.

When the first clamping block and the second clamping block are relatively close to clamp the oil cylinder, the first component 100 and the second component 200 are relatively close to each other and are in a clamping state. When the first clamping block and the second clamping block are relatively far away from the release oil cylinder, the first part 100 and the second part 200 are relatively far away and are in an opening state.

The first member 100 is provided with a first engaging portion 110, and the second member 200 is provided with a second engaging portion 210.

When the first member 100 and the second member 200 are in the clamped state, the first matching part 110 and the second matching part 210 are closer to each other; when the first member 100 and the second member 200 are in the clamped state, the distance between the first fitting portion 110 and the second fitting portion 210 increases.

The driving member 400 is coupled to the locking member 300 for driving the locking member 300 to move. The locking member 300 is formed with an accommodating portion 322, and the first and second

fitting portions

110 and 210 can be fitted with the accommodating portion 322 when they are closely spaced.

When the first member 100 and the second member 200 are clamped, the driving member 400 drives the locking member 300 to move, so that the accommodating portion 322 of the locking member 300 can be covered outside the first mating portion 110 and the second mating portion 210. Therefore, the inner wall of the accommodating part 322 is used for blocking the first matching part 110 and the second matching part 210 from relatively departing, so that the first component 100 and the second component 200 are limited to move, the purpose of keeping the first component 100 and the second component 200 in a clamping state is achieved, and the first clamping block and the second clamping block are kept clamped.

That is, in the present application, the accommodating portion 322 with a constant space is disposed on the locking member 300, and the accommodating portion 322 is used to cooperate with the first matching portion 110 and the second matching portion 210 at a close distance, so as to achieve the purpose of locking.

Under the action of the locking mechanism 1, the driving force of the external driving mechanism can be cancelled, and the energy-saving effect is achieved. For example, the external driving force of the first clamping block and the second clamping block can be removed after the two clamping blocks are driven to clamp the oil cylinder. As well as the aforementioned driving force applied to the locking member 300 by the driving member 400, the accommodating portion 322 can be removed after the accommodating portion 322 is covered on the first matching portion 110 and the second matching portion 210 by driving the locking member 300 to move to the proper position. The driving force is cancelled, and the clamping effect of the oil cylinder is not influenced.

The locking member 300 includes a slider 310 and a locking block 320, a receiving portion 322 is formed on the locking block 320, and the slider 310 is connected to an output end of the driving member 400, so that the driving member 400 drives the locking block 320 through the slider 310.

The slider 310 is configured to move in a first direction x, and the locking block 320 is configured to be movable in a second direction y when the slider 310 moves in the first direction x, the first direction x being perpendicular to the second direction y. This allows the locking member 300 and the actuating member 400 to occupy less space in the second direction y, so that the overall structure is compact.

The structure of the locking block 320 is as shown in fig. 2, the locking block 320 includes a first side plate 325, a second side plate 326 and a bottom plate 327, the first side plate 325 and the second side plate 326 are disposed oppositely, the bottom plate 327 is perpendicular to the first side plate 325 and the second side plate 326 and is connected to the length direction of the first side plate 325 and the second side plate 326, so that a strip-shaped groove 321 is formed between the first side plate 325, the second side plate 326 and the bottom plate 327, a side wall of the strip-shaped groove 321 is formed on the first side plate 325 and the second side plate 326, and a bottom wall of the strip-shaped groove 321 is formed on the bottom plate 327.

The accommodating portion 322 is a groove formed on a side wall of the strip groove 321, the groove being recessed from an opening edge of the strip groove 321 toward a bottom wall of the strip groove 321. In other words, an edge of at least one of the first side plate 325 and the second side plate 326 away from the bottom plate 327 is recessed to form a notch along a direction perpendicular to the bottom plate 327.

The aforementioned slider 310 is located in the strip-shaped groove 321, and since both ends of the strip-shaped groove 321 are not closed, it is possible to conveniently connect the slider 310 and the driving member 400 from either end of the strip-shaped groove 321.

A guide inclined groove 323 is formed on a side wall of the strip-shaped groove 321, a protruding pin 311 is formed on the slider 310, and the pin 311 is fitted to the guide inclined groove 323. When the slider 310 is subjected to a force sliding along the strip-shaped groove 321, the pin 311 moves along the guide chute 323, and the slider 310 can approach or separate from the bottom wall of the strip-shaped groove 321, i.e., the slider 310 can approach or separate from the bottom plate 327 under the guiding action of the guide chute 323.

The guide chute 323 may be a side wall penetrating or not penetrating the strip groove 321, and in the present embodiment, the guide chute 323 is configured to penetrate the side wall of the strip groove 321 to facilitate inspection and repair. In other words, at least one of the first side plate 325 and the second side plate 326 forms a guide chute 323 that penetrates the plate surface.

The first direction x is the same as the extending direction of the groove 321, and the second direction y is perpendicular to the bottom plate 327. Therefore, when the slider 310 moves along the first direction x, the locking block 320 is driven to move along the second direction y.

To ensure that the receiving portion 322 is accurately positioned, the slider 310 is movably coupled to the first component 100. The first member 100 is provided with a slide rail 120, and the slider 310 is mounted on the slide rail 120. The driving unit 400 drives the sliding block 310 to move along the sliding rail 120, and the driving unit 400 may be configured as a linear driving mechanism such as an air cylinder, an electric cylinder, a linear module, a motor nut assembly, and the like.

In order to limit the movement of the locking block 320 along the first direction x and ensure that the locking block 320 can move along the second direction y, a limiting surface 324 is further formed on the locking block 320, when the limiting surface 324 abuts against the first matching portion 110, the locking block 320 can move along the first direction x to guide the locking block 320 to move along the second direction y under the action of the guiding inclined groove 323, and the accommodating portion 322 is covered with the first matching portion 110 and the second matching portion 210.

In this embodiment, the position-limiting surface 324 is coplanar with the first stopping surface 3221, so that the position-limiting surface 324 is engaged with the first engaging portion 110, in other embodiments, the position-limiting surface 324 may also be disposed at other positions of the locking block 320, and a protrusion for stopping the position-limiting surface 324 is formed at other positions of the first component 100.

In addition to the locking block 320 being provided as a separate structure as shown in fig. 2, the locking block 320 may be formed as an integral body, the receiving portion 322 is recessed from the first surface of the locking block 320 along the second direction y, the strip-shaped groove 321 is recessed from the second surface of the locking block 320 along the first direction x, and the guiding inclined groove 323 is recessed from the third surface of the locking block 320 along a third direction perpendicular to the first direction x and the second direction y.

The receiving portion 322 may have any shape such as a cylindrical shape, a right prism shape, etc., and may also be a frame as shown in fig. 2, as long as the inner wall of the receiving portion 322 includes two first stopping surfaces 3221 and second stopping surfaces 3222 arranged oppositely.

The spacing between the first and second stop surfaces 3221, 3222 is configured to: when the first member 100 and the second member 200 are in the clamped state, a distance between an edge of the first fitting portion 110 on a side away from the second fitting portion 210 and an edge of the second fitting portion 210 on a side away from the first fitting portion 110, that is, a distance between an edge of the first fitting portion 110 on a side away from the second fitting portion 210 and an edge of the second fitting portion 210 on a side away from the first fitting portion 110 when the distance between the first fitting portion 110 and the second fitting portion 210 is relatively short.

The first and

second components

100 and 200 are configured as shown in fig. 3, wherein the first mating portion 110 includes a first mating surface 111 and a third mating surface 112, and the second mating portion 210 includes a second mating surface 211 and a fourth mating surface 212.

The first mating surface 111 is located on a side of the first mating portion 110 away from the second mating portion 210, in other words, an edge of the first mating portion 110 away from the second mating portion 210 is formed on the first mating surface 111.

The second mating surface 211 is located on a side of the second mating portion 210 away from the first mating portion 110, in other words, an edge of the second mating portion 210 away from the first mating portion 110 is formed on the second mating surface 211.

That is, when the accommodating portion 322 covers the first matching portion 110 and the second matching portion 210, the first stopping surface 3221 contacts the first matching surface 111, and the second stopping surface 3222 contacts the second matching surface 211.

The third mating surface 112 and the fourth mating surface 212 are disposed opposite to each other, and when the first component 100 and the second component 200 are in the clamped state, the third mating surface 112 and the fourth mating surface 212 abut against each other, so as to prevent the first mating portion 110 and the second mating portion 210 from being damaged due to an excessive stress.

The structure of the hydraulic cylinder loading device and the locking mechanism 1 thereof according to the embodiment of the present application is described above, and the operation principle of the embodiment of the present application is explained below, and if not described in detail, the operation principle can be combined with fig. 1 to 3 and refer to the foregoing.

At this time, the first clamping block and the second clamping block clamp the oil cylinder by the driving force from the outside.

Fig. 5 shows a state diagram of the locking member 300 at the second position, as shown in fig. 5, the driving member 400 drives the slider 310 to drive the locking block 320 to move left along the first direction x to approach the first engaging portion 110 and the second engaging portion 210 until the limiting surface 324 of the locking block 320 abuts against the first engaging portion 110. At this time, the locking block 320 is positioned above the first and second

fitting portions

110 and 210, and the opening of the receiving portion 322 is aligned with the first and second

fitting portions

110 and 210.

After the locking member 300 reaches the second position, as shown in fig. 6, the driving member 400 continues to drive the sliding block 310 to move leftward along the first direction x, due to the action of the limiting surface 324, the locking block 320 cannot move leftward along the first direction x, and the limiting surface 324 guides the locking block 320 to move downward along the second direction y under the action of the guiding inclined groove 323 and the pin 311, so that the locking member 300 reaches the third position shown in fig. 6. When the locking assembly 300 is at the third position, the accommodating portion 322 of the locking block 320 is covered on the first engaging portion and the second engaging portion, and the inner wall of the accommodating portion 322 blocks the first engaging portion and the second engaging portion from being away from each other, that is, the first blocking surface 3221 is blocked by the first engaging surface 111, and the second blocking surface 3222 is blocked by the second engaging surface 211. At this time, the first member 100 and the second member 200 are locked in the clamping state, so that the first clamping block and the second clamping block clamp the oil cylinder, and the driving force provided by the driving member 400 and the driving force provided to the two clamping blocks can be cancelled.

And (3) a release process:

the release process is the reverse of the clamping process.

The locking mechanism 1 is first in the state shown in fig. 6, the locking member 300 is in the third position, the driving member 400 drives the slider 310 to move rightward along the first direction, the locking block 320 cannot move rightward along the first direction x due to the second stopping surface 3222 of the accommodating portion 322, the second stopping surface 3222 guides the locking block 320 to move upward along the second direction y under the action of the guiding inclined groove 323 and the pin 311, so that the locking member 300 reaches the second position in the state shown in fig. 5, and the accommodating portion 322 on the locking block 320 is disengaged from the first engaging block and the second engaging block.

After the first matching portion 110 and the second matching portion 210 are released by the accommodating portion 322, the second blocking surface 3222 is disengaged from the second matching surface 211, the driving unit 400 continues to drive the slider 310 to move rightward along the first direction, and drives the locking block 320 to leave the locking block 320 and be located above the first matching portion 110 and the second matching portion 210, so that the locking unit 300 returns to the first position shown in fig. 4.
