Abstract
The invention provides a hydraulic screw disassembling device which comprises a hydraulic cylinder, wherein an oil cylinder tail support is arranged at one end of the hydraulic cylinder, which is far away from a hydraulic push rod, taper sleeve fixing blocks for fixing and clamping taper sleeves are arranged on the oil cylinder tail support and the hydraulic push rod, the central axes of the two taper fixing blocks and the two clamping taper sleeves are superposed and are consistent with the telescopic direction of the hydraulic push rod, and the running direction of a spiral sleeve in the disassembling process is kept highly superposed with the central axis of a main shaft by superposing the two taper fixing blocks and the central axes of the two clamping taper sleeves and being consistent with the telescopic direction of the hydraulic push rod, so that the deformation of a plurality of limiting teeth on the main shaft and a plurality of limiting tooth grooves in the inner cavity of the spiral sleeve, which is caused by the inconsistency of the running direction of the spiral sleeve with the central axis.
Description
Technical Field
The invention relates to the technical field of dismounting devices, in particular to a hydraulic screw dismounting device.
Background
The screw of bulking machine can have water and material infiltration corrosion main shaft and spiral hole on the screw rod in the use to lead to the screw when trading, hardly take out. At present, a screw rod is disassembled by a plurality of companies by a method of manually knocking outwards, in the process, a screw rod bolt is easily damaged, the disassembly is inconvenient, and even flame is used for carrying out damaged disassembly on a screw rod.
Disclosure of Invention
The invention aims to provide a hydraulic screw disassembling device, which solves the defects of the prior art.
The invention is realized by the following technical scheme:
hydraulic pressure screw rod dismounting device, including the pneumatic cylinder, the one end that hydraulic push rod was kept away from to the pneumatic cylinder is provided with the hydro-cylinder afterbody and supports, all be provided with the taper sleeve fixed block that is used for fixed centre gripping taper sleeve on hydro-cylinder afterbody supports and the hydraulic push rod, the central axis coincidence of two toper fixed blocks and two centre gripping taper sleeves just is unanimous with hydraulic push rod's flexible direction.
Through the central axis coincidence setting with two toper fixed blocks and two centre gripping taper sleeves and unanimous with hydraulic push rod's flexible direction for the line footpath direction of spiral cover in dismantling the process keeps high coincidence with the central axis of main shaft, thereby avoids leading to the deformation of a plurality of spacing teeth of epaxial a plurality of spacing teeth and the spacing tooth's socket of spiral cover inner chamber because of the line footpath direction of spiral cover in dismantling the process is inconsistent with the central axis of main shaft.
The clamping taper sleeve arranged on the support at the tail part of the oil cylinder is used for fixing the next section of the screw sleeve to be disassembled and preventing the main shaft from moving along with the screw sleeve during disassembly.
Furthermore, the clamping taper sleeve is detachably arranged on the taper sleeve fixing block.
Furthermore, the conical fixing block and the clamping taper sleeve are both made of light high-strength steel.
Compared with the prior art, the invention has the following advantages and beneficial effects:
according to the hydraulic screw disassembling device, the two conical fixing blocks and the central shafts of the two clamping conical sleeves are arranged in a superposition manner and are consistent with the telescopic direction of the hydraulic push rod, so that the traveling direction of the spiral sleeve in the disassembling process is kept highly coincident with the central axis of the main shaft, and the deformation of a plurality of limiting teeth on the main shaft and a plurality of limiting tooth grooves in the inner cavity of the spiral sleeve due to the fact that the traveling direction of the spiral sleeve in the disassembling process is inconsistent with the central axis of the main shaft is avoided.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic view of the structure of the present invention.
FIG. 2 is a schematic view b of the present invention.
Reference numbers and corresponding part names in the drawings:
the method comprises the following steps of 1-clamping a taper sleeve, 2-fixing a taper sleeve, 3-supporting the tail of an oil cylinder, 4-a hydraulic cylinder, 5-a hydraulic push rod, 6-a spiral sleeve and 7-a main shaft.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following.
Example 1
As shown in fig. 1-2, the hydraulic screw detaching device comprises a hydraulic cylinder 4, wherein an oil cylinder tail support 3 is arranged at one end of the hydraulic cylinder 4 far away from a hydraulic push rod 5, taper sleeve fixing blocks 2 for fixing and clamping taper sleeves 1 are arranged on the oil cylinder tail support 3 and the hydraulic push rod 5, and the central axes of the two taper fixing blocks 2 and the two clamping taper sleeves 1 are overlapped and are consistent with the telescopic direction of the hydraulic push rod 5.
Through the central axis coincidence setting with two toper fixed blocks 2 and two centre gripping taper sleeves 1 and unanimous with hydraulic push rod 5's flexible direction for the path direction of helical casing 6 in the dismantlement process keeps high coincidence with the central axis of main shaft 7, thereby avoids leading to the deformation of a plurality of spacing teeth on the main shaft 7 and a plurality of spacing tooth's socket of helical casing 6 inner chamber because of the path direction of helical casing 6 in the dismantlement process is inconsistent with the central axis of main shaft 7.
The clamping taper sleeve 1 arranged on the oil cylinder tail support 3 is used for fixing the next section of the screw sleeve 6 to be disassembled and preventing the main shaft 7 from moving along with the screw sleeve 6 during disassembly.
Example 2
Based on embodiment 1, centre gripping taper sleeve 1 is detachable to be set up on taper sleeve fixed block 1.
The conical fixing block 2 and the clamping taper sleeve 1 are both made of light high-strength steel.
According to the hydraulic screw dismounting device, the two conical fixing blocks 2 and the central shafts of the two clamping conical sleeves 1 are arranged in a superposed manner and are consistent with the telescopic direction of the hydraulic push rod 5, so that the travelling direction of the spiral sleeve 6 in the dismounting process is kept highly superposed with the central axis of the main shaft 7, and the deformation of a plurality of limiting teeth on the main shaft 7 and a plurality of limiting tooth grooves in the inner cavity of the spiral sleeve 6 caused by the inconsistency between the travelling direction of the spiral sleeve 6 in the dismounting process and the central axis of the main shaft 7 is avoided.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
