Detailed Description
The following describes in detail embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as viewed with reference to the accompanying drawings, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to an aspect of the present application, there is provided a hopper positioning apparatus, wherein the hopper positioning apparatus comprises a first positioning device 100 for positioning a hopper 500 in a first horizontal direction (X direction in fig. 1), a second positioning device 200 for positioning the hopper 500 in a second horizontal direction (Y direction in fig. 1) perpendicular to the first horizontal direction, and a third positioning device 300 for positioning the hopper 500 in a vertical direction (Z direction in fig. 1).
The hopper positioning device can be used for positioning the hopper 500 in three orthogonal directions through the first positioning device 100, the second positioning device 200 and the third positioning device 300 respectively, so that the positioning accuracy of the hopper is ensured, the damage to parts in the assembling process caused by the positioning accuracy is avoided, and the assembling efficiency is improved.
Wherein the first positioning device 100, the second positioning device 200 and the third positioning device 300 may take various suitable forms in order to provide positioning of the hopper 500 in the corresponding directions.
According to an embodiment of the present application, the first positioning device 100 may include a first supporting mechanism 110 for supporting the hopper 500 from the bottom and a first positioning mechanism 120 oppositely disposed along the first horizontal direction, and the first positioning mechanism 120 may be close to or far away from each other along the first horizontal direction to push the hopper supported on the first supporting mechanism 110 to be positioned along the first horizontal direction. Specifically, the hopper 500 may be hoisted above the first support mechanism 110 by an auxiliary device (e.g., a hoist) to be supported by the first support mechanism 110, and then the positioning of the hopper 500 in the first horizontal direction may be completed by bringing the two first positioning mechanisms 120 close to each other to push the hopper 500 to move to the set position in the first horizontal direction.
The first positioning mechanisms 120 may be provided in various suitable forms as long as the two first positioning mechanisms 120 can be close to or far away from each other. In the embodiment shown in fig. 5, the first positioning mechanism 120 may include a first positioning cylinder and a horizontal pressing block 121 disposed at a piston end of the first positioning cylinder, and the first positioning cylinder stretches and retracts to drive the horizontal pressing block 121 to move so as to push the hopper 500 to move in the first horizontal direction for positioning.
In order to reduce the frictional resistance between the hopper 500 and the first supporting mechanism 110 when the hopper 500 moves in the first horizontal direction, the first supporting mechanism 110 may support only both sides of the bottom of the hopper 500. To this end, as shown in fig. 5, the first positioning device 100 includes two first supporting mechanisms 110 oppositely disposed in the first horizontal direction to support the hopper from both sides, and the first positioning mechanism 120 is disposed on the first supporting mechanisms 110.
In addition, the first support mechanism 110 is configured to provide elastic support to cushion the impact of the hopper 500 placed on the first support mechanism 110. Specifically, the first support mechanism 110 may include a first support cylinder 111 and a first support 112 disposed at a piston end of the first support cylinder 111, a first elastic support 113 may be disposed on the first support 112, and the hopper 500 may be supported on the first elastic support 113.
In addition, to stably support the hopper 500, support may be provided from both front and rear ends of the hopper 500. As shown in fig. 5, the first positioning device 100 may include a second support mechanism 140 to provide support from both ends of the hopper 500 by the first support mechanism 110 and the second support mechanism 140. Specifically, two second support mechanisms 140 may be provided to be disposed oppositely along the first horizontal direction and support the hopper 500 from both sides. The second supporting mechanism 140 may have a structure similar to that of the first supporting mechanism 110, and specifically includes a second supporting cylinder 141 and a second supporting portion 142 disposed at an end of a piston of the second supporting cylinder 141, a second elastic supporting member 143 may be disposed on the second supporting portion 142, and the hopper 500 is supported on the second elastic supporting member 143 (e.g., by a front cross web 530). When the hopper 500 is pushed to be positioned in the first horizontal direction by the first positioning mechanism 120, the hopper 500 moves on the first and second elastic supports 113 and 143.
Furthermore, to avoid accidental movement of the hopper 500, the first positioning device 100 may be provided with a limiting structure for limiting the hopper 500 in the second horizontal direction and/or an anti-tipping structure 130 for preventing tipping of the hopper.
Specifically, the limiting structure may be realized by matching the specific structures of the first supporting portion 112 and the second supporting portion 142 with the corresponding components of the hopper 500. For example, the first support part 112 may have a first shutter 112a to contact an end surface of the seat plate 540 of the hopper 500, and a similar side end surface of the second support part 142 may contact the front wall plate 530 of the hopper 500, thereby restricting the position of the hopper 500 at both sides of the hopper 500 in the second horizontal direction.
The anti-tipping structure 130 may be disposed on both sides of the hopper 500, for example, mounted on the first support mechanism 110. Specifically, the anti-tipping structure 130 may include an anti-tipping cylinder and a tipping block 131 disposed at a piston end of the anti-tipping cylinder, and after the hopper 500 is positioned in the first horizontal direction by the first positioning mechanism 120, the anti-tipping cylinder may be extended to wedge the tipping block 131 with a specific position (e.g., a seat plate 540) on the hopper 500 to lock the hopper 500, thereby preventing the hopper 500 from tipping at a large angle. Meanwhile, the position of the hopper 500 within the plane defined by the first horizontal direction and the vertical direction may be substantially positioned.
Preferably, the first positioning device 100 is configured to adjust the distance between two first supporting mechanisms 110 along the first horizontal direction to adapt to the positioning of different types of hoppers 500. Alternatively, in the case of having the second support mechanisms 140, the positions between the second support mechanisms 140 may be made adjustable.
In addition, in order to facilitate the positioning operation of the second positioning device 200 and the third positioning device 300, the first positioning device 100 is provided to be movable in the second horizontal direction.
Specifically, as shown in fig. 5, the first positioning device 100 may include a first direction adjustment mechanism 150, a second direction adjustment mechanism 160, and a first support 170, the first direction adjustment mechanism 150 may be an air cylinder that extends and contracts in a first horizontal direction, the second direction adjustment mechanism 160 may be an air cylinder that extends and contracts in a second horizontal direction, one of the first direction adjustment mechanism 150 and the second direction adjustment mechanism 160 may be mounted to the other, the first support mechanism 110 and the second support mechanism 140 may be mounted to the one, and the other may be mounted to the first support 170. Thus, the movement of the first and second support mechanisms 110 and 140 in the first and second horizontal directions may be achieved by the extension and contraction of the first and second direction adjustment mechanisms 150 and 160.
The second positioning device 200 may be provided in various suitable forms to position the second horizontal direction of the hopper 500 by the corresponding structure of the hopper 500. In an embodiment of the present application, as shown in fig. 6 and 7, the second positioning device 200 may include a second positioning mechanism 210 for positioning the concrete pipe fitting hole 510 of the hopper 500 and a moving mechanism 220 for driving the second positioning mechanism 210 to move in the second horizontal direction with respect to the first positioning device 100, the first and second positioning devices 100 and 200 being provided to be movable together in the second horizontal direction. The second positioning mechanism 210 may be moved to the hopper 500 positioned in the first horizontal direction by the first positioning device 100 by the moving mechanism 220 to position the concrete pipe fitting hole 510 of the hopper 500 by the second positioning mechanism 210. After the concrete pipe fitting hole 510 is positioned by the second positioning mechanism 210, the first positioning means 100 and the second positioning means 200 can be moved together in the second horizontal direction to a predetermined position to complete the positioning of the hopper 500 in the second horizontal direction.
In this case, the second positioning mechanism 210 can position the concrete pipe fitting hole 510, thereby positioning the hopper 500 with respect to the second positioning device 200 with high accuracy. Subsequently, by moving the first and second positioning devices 100 and 200 in the second horizontal direction, accurate positioning of the hopper 500 in the second horizontal direction can be ensured.
To achieve accurate positioning of the concrete pipe fitting hole 510 by the second positioning mechanism 210, the second positioning mechanism 210 may be configured to be capable of accurately fitting with the concrete pipe fitting hole 510. Specifically, the second positioning mechanism 210 may include a slider 211 and a plurality of expansion blocks 212 abutting against the concrete pipe assembling hole 510 along a circumferential direction of the concrete pipe assembling hole 51, the slider 211 having a diverging portion, and the expansion blocks 212 being disposed around the slider 211 and cooperating with the diverging portion to expand and contract in a direction perpendicular to a moving direction of the slider 211 when the slider 211 moves. Therefore, the expansion block 212 can be firstly extended into the concrete pipe assembling hole 510 in the contraction state, and then the sliding block 211 slides to be extended out of the expansion block 212, so that the expansion block 212 can be completely matched with the concrete pipe assembling hole 510.
Here, the second positioning device 200 and the first positioning device 100 may have a fixed relative position in the first horizontal direction, so that the center around which the expansion block 212 is located can be located on the axis of the concrete pipe fitting hole 510 of the hopper 500 positioned by the first positioning device 100. The second positioning mechanism 210 is moved by the moving mechanism 220, so that the expansion block 212 reaches the assembly hole 510 and just matches with the concrete pipe assembly hole 510 after being extended.
The gradually expanding portion of the slider 211 may be tapered, for example, may be a circular truncated cone structure, and the expanding block 212 has an arc surface that fits with the outer periphery of the circular truncated cone structure. To realize the sliding of the sliding block 211, various suitable mechanisms can be used, for example, the sliding block 211 can be driven by a telescopic rod to slide. In the embodiment shown in fig. 7, the sliding block 211 may be connected to a screw block 213, and the screw block 213 has an internal thread and forms a screw-nut mechanism with a screw 214, so that the screw 214 is driven by a motor 216 to rotate, such that the sliding block 211 is driven by the screw block 213 to slide, and the expansion block 212 is extended and contracted. Wherein, the second positioning mechanism 210 may include a housing 217, and the expansion block 212 is mounted to the housing 217 to maintain a position of the expansion block 212 in a sliding direction of the slider 211 by the housing 217 and to allow the expansion block 212 to be extended and contracted. The motor 216 may be mounted to the housing 217 by a mount 215.
To facilitate the movement of the first positioning device 100 and the second positioning device 200 in the second horizontal direction, the second positioning device 200 includes a base 230, the second positioning mechanism 210 is mounted on the base 230 through the moving mechanism 220, the first positioning device 100 is mounted on the base 230 (specifically, the first support 170 may be mounted on the base 230), and the hopper positioning apparatus includes an integral moving device 400 for moving the base 230 in the second horizontal direction. Wherein, the base 230 and the first positioning device 100 mounted on the base 230 can be driven to move along the second horizontal direction by the integral moving device 400. Specifically, after the second positioning mechanism 210 and the concrete pipe assembling hole 510 are positioned, the integral moving device 400 may move the base 230 so that the hopper 500 positioned in the first horizontal direction is moved to a predetermined position in the second horizontal direction, and the positioning of the hopper 500 in the second horizontal direction is completed.
The third positioning means 300 may be provided in various suitable forms to position the vertical position of the hopper 500 by the corresponding structure of the hopper 500. In a preferred embodiment of the present application, as shown in fig. 6, the third positioning device 300 may include a third positioning mechanism 310 for positioning the concrete cylinder fitting hole 520 of the hopper 500, and the third positioning mechanism 310 includes two positioning shafts 311 which are disposed flush in the vertical direction and precisely engaged with the concrete cylinder fitting hole 520. As shown in fig. 4, the hopper 500 has two concrete cylinder assembly holes 520 arranged in parallel, and the two positioning shafts 311 of the third positioning mechanism 310 are arranged to be precisely engaged with the two concrete cylinder assembly holes 520, respectively.
It will be appreciated that the third positioning device 300 should have a corresponding position in the first horizontal direction with respect to the hopper 500 positioned by the first and second positioning devices 100 and 200. That is to say, after the first positioning device 100 and the second positioning device 200 are positioned, the positions of the concrete cylinder assembly holes 520 of the hopper 500 in the first horizontal direction are consistent with the corresponding positioning shafts 311, so that the third positioning mechanism 310 can be kept at a required position during positioning, and only by moving the hopper 500 to a predetermined position in the second horizontal direction through the integral moving device 400, the two concrete cylinder assembly holes 520 can just reach positions precisely matched with the two positioning shafts 311, that is, the final positioning positions.
Since the hopper 500 has been preliminarily positioned in the vertical direction by the cooperation of the second positioning mechanism 210 and the concrete pipe fitting hole 510 at the time of positioning by the second positioning device 200, the accurate fitting of the positioning shaft 311 of the third positioning device 300 to the concrete cylinder fitting hole 520 (the fitting accuracy is higher than that of the second positioning mechanism 210 to the concrete pipe fitting hole 510) will make the positioning in the vertical direction more accurate.
The positioning shaft 311 is provided to be adjustable in position in the vertical direction in order to be suitable for providing vertical positioning of different types of hoppers 500 (the height of the concrete cylinder fitting hole 520 may be different). Specifically, as shown in fig. 6, the third positioning mechanism 310 may include a mounting plate 312, a vertical guide rail 314, and a lifting cylinder 315, the positioning shaft 311 may be mounted on the mounting plate 312, the mounting plate 312 is mounted at a piston end of the lifting cylinder 315 and is in sliding fit with the vertical guide rail 314, and the lifting cylinder 315 may lift the mounting plate 312, so that the mounting plate 312 drives the positioning shaft 311 to lift along the vertical guide rail 314.
Alternatively, the distance between the concrete cylinder fitting holes 520 may be varied, and for this purpose, the horizontal distance between the two positioning shafts 311 may be adjusted. Specifically, two horizontal guide rails 313 may be mounted on the mounting plate 312, and the two positioning shafts 311 are respectively configured to be movable along the corresponding horizontal guide rails 313 (for example, mounted on a horizontal slider that slides along the horizontal guide rails 313, and the horizontal slider may be driven by an air cylinder).
Wherein, the lifting cylinder 315 and the vertical guide rail 314 can be installed on a proper installation base. For example, a fixing device 600 may be provided, the lifting cylinder 315, the vertical guide 314, and the whole moving device 400 may be mounted on the fixing device 600, and the first positioning mechanism 110, the second positioning mechanism 210, and the third positioning mechanism 310 may all move with the fixing device 600 as a reference to determine a specific position (i.e., XYZ three-axis coordinates set with the fixing device 600 as a reference). Wherein the fixing device 600 may be in the form of a table, a frame, etc.
According to another aspect of the present application, there is provided a hopper positioning method, wherein the hopper positioning method includes:
s1, positioning the hopper 500 in the first horizontal direction;
s2, positioning the hopper 500 in a second horizontal direction perpendicular to the first horizontal direction;
s3, positioning the hopper 500 in a vertical direction.
The hopper positioning method can be used for positioning the hopper 500 in three orthogonal directions respectively so as to ensure the positioning accuracy of the hopper, avoid part damage in the assembly process caused by the positioning accuracy, and improve the assembly efficiency.
Wherein the positioning of the first horizontal direction, the second horizontal direction and the vertical direction may be provided for the hopper 500 in various ways, for example by positioning different parts of the hopper 500. Preferably, step S1 may include abutting the hopper 500 from both sides of the hopper 500 in the second horizontal direction; step S2 may include positioning the concrete pipe fitting hole 510 of the hopper 500 in the second horizontal direction; step S3 may include positioning concrete cylinder fitting holes 520 of the hopper 500 in a vertical direction.
Since the hopper 500 has been preliminarily positioned in the vertical direction by the positioning of the concrete pipe fitting hole 510 at the time of the positioning by the step S2, the step S3 can calibrate the step S2 by the vertical direction positioning of the concrete cylinder fitting hole 520 to achieve more accurate vertical direction positioning. Specifically, the positioning may be achieved by the engagement with the concrete pipe fitting hole 510 in step S2, and the positioning may be achieved by the engagement with the concrete cylinder fitting hole 520 in step S3. In order to calibrate the vertical direction positioning of step S2 and to achieve accurate vertical direction positioning through step S3, the vertical direction positioning can be made more accurate through accurate fitting with the concrete cylinder fitting hole 520 in step S3 (the fitting accuracy is higher than that with the concrete pipe fitting hole 510 in step S2).
According to another aspect of the present application, there is provided a hopper assembly method, wherein the hopper assembly method includes:
positioning the hopper 500 using the hopper positioning method of the present application;
and keeping the positioned position of the hopper 500, and assembling the hopper 500 with a concrete cylinder, a water tank and an oil cylinder.
Through accurate positioning hopper 500, subsequent assembly precision can be ensured, for example, the coaxiality of the concrete cylinder assembly hole and the long-span shaft hole of the concrete cylinder, the oil cylinder and other related components is ensured.
The methods of the present application may be carried out by suitable apparatus. For example, the hopper 500 may be positioned using the hopper positioning apparatus of the present application.
The process of positioning the hopper by the hopper positioning apparatus of the present application is described below with reference to the accompanying drawings.
First, as shown in fig. 1, the first positioning device 100, the second positioning device 200, and the third positioning device 300 are set to have relative positions in the first horizontal direction (X direction) fixed to each other, and the second positioning device 200 and the third positioning device 300 are set to have relative positions in the vertical direction (Z direction) fixed to each other, so that after the hopper 500 is positioned by the first positioning device 100, the axis of the concrete pipe fitting hole 510 thereof passes through the center surrounded by the expansion block 212 of the second positioning mechanism 210, and the axis of the concrete cylinder fitting hole 520 thereof is substantially coaxial with the corresponding positioning shaft 311 of the third positioning device 300.
The hopper 500 is placed on the first support mechanism 110 and the second support mechanism 140, and the hopper 500 is pushed to move in the first horizontal direction by extending the horizontal pressing block 121 until both sides of the hopper 500 abut against the horizontal pressing block 121, and the hopper 500 reaches a predetermined position in the first horizontal direction. The ramp block 131 is then extended to wedge with the seat plate 540 of the hopper 500, preventing a large angle tipping of the hopper 500.
Subsequently, the second positioning mechanism 210 is moved to a predetermined position in the second horizontal direction (Y direction) by the moving mechanism 220 so that the expansion block 212 enters the concrete pipe fitting hole 510. Then, drive lead screw 214 through motor 217 and rotate, make screw block 213 drive slider 211 and rotate then to make bloated shape piece 212 stretch out and butt cooperation concrete pipe pilot hole 510. The first and second positioning devices 100 and 200 and the hopper 500 are moved together to the set position in the second horizontal direction by the overall moving device 400 to complete the positioning in the second horizontal direction. Meanwhile, the positioning shaft 311 of the third positioning device 300 has been located at a position substantially coaxial with the concrete cylinder fitting hole 520 of the hopper 500. When the hopper 500 is moved in place by the moving device 400, the concrete cylinder assembly hole 520 is just matched with the positioning shaft 311, so that the vertical direction position of the concrete cylinder assembly hole 520 is accurately adjusted through the positioning shaft 311, and the hopper 500 is positioned in the vertical direction.
It will be appreciated that the hopper positioning apparatus of the present application may provide a locking function for the respective support mechanism, positioning mechanism, among others. For example, a lock function (e.g., provision of a lock cylinder) may be provided for the first support cylinder 111, the second support cylinder 141, the lift cylinder 315, and the like to ensure stability of the positioning position. Wherein each positioning mechanism can be locked after the hopper 500 has been positioned to ensure a positioned position, removal of a portion of the positioning mechanism does not affect the hopper 500 remaining in the positioned position. For the convenience of subsequent assembly, after the vertical positioning is completed by the third positioning device 300, in order to avoid interference of subsequent assembly, the first positioning device 100, the second positioning device 200 and the hopper 500 may be retreated together in the second horizontal direction by the integral moving device 400, so that the third positioning device 300 is separated from the hopper 500, an assembly space is made available, and then assembly may be started, for example, connecting a concrete cylinder, a water tank, an oil cylinder, etc. The first positioning device 100 and the second positioning device 200 can be released correspondingly according to the assembling progress so as to avoid the assembling and avoid the interference.
