Description

Technical Field

[0001] The utility model relates to the field of pneumatic hydraulic stations, in particular to a hydraulic pneumatic device fixing base. Background Art

[0002] Pneumatic hydraulic station, also known as air pressure station or hydraulic station for short, refers to equipment that uses gas and liquid to drive actuators. It usually consists of several parts, such as gas source, liquid source, actuators, and control elements. Among them, the gas source often uses compressed air, and the liquid source is common hydraulic oil.

[0003] Traditional pneumatic hydraulic stations still have certain shortcomings during use: First, pneumatic hydraulic stations are mostly used in machine tools and industrial automation fields, and are usually used as fixtures. However, when installing pneumatic hydraulic stations near machine tools and other places, the machine tools themselves are not equipped with a special pneumatic hydraulic station base, which makes it inconvenient to install the machine body near the cylinder and fixture. In addition, since the hydraulic station itself has a large mass after oil filling, it is very troublesome for workers to carry it back and forth. Secondly, during the use of pneumatic hydraulic stations, it is easy for the harsh processing environment to cause a lot of impurities to adhere to the joints of the hydraulic valve components, oil filling ports and pneumatic pumps, which not only aggravates the aging of the structure, but also makes it inconvenient for subsequent maintenance.

[0004] Therefore, it is necessary to provide a new hydraulic pneumatic device fixed base to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a hydraulic pneumatic device fixing base which can effectively prevent dust in a processing environment from corroding a pneumatic hydraulic station and has a base with a flexibly adjustable position and height.

[0006] In order to solve the above technical problems, the utility model provides a fixed base of a hydraulic pneumatic device, comprising: an adjusting component and a protective component, wherein the lower side and the upper side of the adjusting component are respectively provided with a base and a lifting platform, and the surfaces of the base and the lifting platform are both transversely provided with sliding grooves, and the adjusting component comprises a scissor-type lifting frame, and the top and the bottom of the scissor-type lifting frame are respectively provided with a fixed shaft and a movable shaft, and the two movable shafts are respectively slidably connected with the sliding grooves on the upper and lower sides, and a threaded rod is rotatably connected to one side wall of the base, and the movable shaft is threadedly connected to the threaded rod through a threaded sleeve, and one end of the threaded rod passes through the side wall surface of the base and is fixedly connected with a crank handle;

[0007] The top of the lifting platform is fixedly connected to a support member by bolts, and the bottom surface of the support member is rotatably connected to a double-headed screw through a connecting member, and nuts are threadedly connected to the left and right sides of the double-headed screw, and a mounting bracket is fixedly connected to the surface of the nut, and the mounting bracket is slidably connected to the support member, and the end of the mounting bracket is connected to a cover body by bolts, the two cover bodies match each other and are both located on the upper side of the support member, and sponges are bonded to the side wall surfaces of the two cover bodies, and a first bevel gear is installed at the center position of the double-headed screw, and a second bevel gear is meshed at one side of the first bevel gear, and a transmission rod is fixedly connected to the end of the second bevel gear, and the transmission rod is rotatably connected to the side wall of the support member.

[0009] Through the above technical scheme, when the pneumatic hydraulic station is currently installed near machine tools and other places, since the machine tool itself is not equipped with a special pneumatic hydraulic station fixing seat, it is not convenient to install the machine body near the cylinder and the fixture, and since the hydraulic station itself has a large mass after oiling, it is very troublesome for workers to carry it back and forth. Therefore, the structure sets a special base for the hydraulic station. The user can first put it into the installation groove, and then move the structure to the appropriate position of the processing machine tool through the cooperation of the handrail and the universal wheel, and make the movable plate contact with the ground by tightening the fastening bolts to fix the device here, and then rotate the crank to allow the movable shaft threadedly connected to the threaded rod to move horizontally, so that the scissor-type folding frame drives the hydraulic station body to rise to a suitable height, which is convenient for workers to connect the oil pipeline on the hydraulic valve group to the two ends of the telescopic cylinder on the fixture through a hose. This structural setting not only facilitates workers to carry the hydraulic station body, but also provides convenience for the installation and use of instruments.

[0010] As a further solution of the utility model, ear plates are fixedly connected to the front and rear side wall surfaces of the base, fastening bolts are threadedly connected to the surfaces of the ear plates, and a movable plate is provided at the bottom of the fastening bolts.

[0011] Through the above technical solution, the movable plate is moved downward and in contact with the ground by tightening the fastening bolts, thereby preventing the structure from moving under the drive of the universal wheel.

[0013] Through the above technical solution, during the use of the pneumatic hydraulic station, it is easy for the harsh processing environment to cause a lot of impurities to adhere to the joints of the hydraulic valve assembly, the oil filling port and the pneumatic pump, which not only aggravates the aging of the structure, but also makes it inconvenient for subsequent maintenance. Therefore, the device adds a cover to the hydraulic station body. The cover is made of transparent material, and the user can observe the internal pressure gauge value and other conditions from the outside. At the same time, the cover is designed to be an openable and closable structure. The user rotates the knob and transmits kinetic energy to the two sets of mounting frames on the double-headed screw through the engagement of the first bevel gear and the second bevel gear, so that the two covers can move toward the middle synchronously, wrapping the hydraulic station body in the center. At the same time, a sponge clip is set on one side of the cover to clamp the pipe connecting the hydraulic valve group and the telescopic cylinder in the middle, which can effectively prevent external dust and other impurities from entering the inside of the cover.

[0017] Through the above technical solution, when in use, the oil pipeline is connected to the corresponding telescopic cylinder through a hose. At this time, the oil pipeline is clamped between two sponges, which can prevent external dust from entering the inside of the cover.

[0018] As a further solution of the utility model, the cover body is made of a transparent material, and the transmission rod penetrates the side wall surface of the support member and is connected to a knob.

[0019] Through the above technical solution, the cover body is made of transparent material, which makes it convenient for users to observe the working conditions of the internal instruments. A knob is installed on one side of the transmission rod, which is conducive to the user to quickly adjust the opening and closing of the cover body.

[0020] Compared with the related art, the hydraulic pneumatic device fixed base provided by the utility model has the following beneficial effects:

[0021] 1. In the utility model, when the pneumatic hydraulic station is currently installed near the machine tool and other places, since the machine tool itself is not equipped with a special pneumatic hydraulic station fixing seat, it is inconvenient to install the machine body near the cylinder and the fixture, and since the hydraulic station itself has a large mass after oiling, it is very troublesome for workers to carry it back and forth. Therefore, the structure sets a special base for the hydraulic station. The user can first put it into the installation groove, and then move the structure to the appropriate position of the processing machine tool through the cooperation of the handrail and the universal wheel, and make the movable plate contact with the ground by screwing the fastening bolts, so that the device is fixed here, and then rotate the crank to make the movable shaft threadedly connected to the threaded rod move horizontally, so that the scissor-type folding frame drives the hydraulic station body to rise to a suitable height, so that the workers can connect the oil pipeline on the hydraulic valve group to the two ends of the telescopic cylinder on the fixture through the hose. This structural setting is convenient for workers to carry the hydraulic station body, and also provides convenience for the installation and use of the instrument;

[0022] 2. In the utility model, during the use of the pneumatic hydraulic station, it is easy for a lot of impurities to adhere to the connection between the hydraulic valve assembly, the oil filling port and the pneumatic pump due to the harsh processing environment, which not only aggravates the aging of the structure, but also makes it inconvenient for subsequent maintenance. Therefore, the device adds a cover to the hydraulic station body. The cover is made of transparent material, and the user can observe the internal pressure gauge value and other conditions from the outside. At the same time, the cover is designed to be an openable and closable structure. The user rotates the knob and transmits the kinetic energy to the two sets of mounting frames on the double-headed screw through the meshing of the first bevel gear and the second bevel gear, so that the two covers can be synchronized. Move closer to the middle and wrap the hydraulic station body in the center. At the same time, a sponge clip is set on one side of the cover to clamp the pipe connecting the hydraulic valve group and the telescopic cylinder in the middle, which can effectively prevent external dust and other impurities from entering the inside of the cover. The pneumatic hydraulic station does not rely on the oil pump and motor to absorb oil. Therefore, the oil temperature is low during operation, and there is no heat generated by the motor. The overall working temperature is not high and is close to the indoor temperature, so that the structure can operate normally inside the cover without worrying about heat dissipation. If the temperature of the working environment in the factory is high, for safety reasons, the user can install a cooling fan on the surface of the cover. BRIEF DESCRIPTION OF THE DRAWINGS

The movable shaft 10 is threadedly connected to the threaded rod 9 through a threaded sleeve 22. One end of the threaded rod 9 passes through the side wall surface of the base 1 and is fixedly connected with a crank 19.

The left and right sides of the double-headed screw 16 are threaded with nuts, and the surface of the nut is fixedly connected to a mounting frame 26. The mounting frame 26 is slidably connected to the support member 6. The end of the mounting frame 26 is connected to a cover body 28 by bolts. The two cover bodies 28 match each other and are both located on the upper side of the support member 6. Sponges 27 are bonded to the side wall surfaces of the two cover bodies 28. A first bevel gear 24 is installed at the center of the double-headed screw 16, and a second bevel gear 25 is meshed at one side of the first bevel gear 24. The end of the second bevel gear 25 is fixedly connected to a transmission rod, and the transmission rod is rotatably connected to the side wall of the support member 6.

[0034] At present, when installing a pneumatic hydraulic station near a machine tool or the like, since the machine tool itself is not equipped with a special pneumatic hydraulic station fixing seat, it is not convenient to install the machine body near the cylinder and the fixture. In addition, since the hydraulic station itself has a large mass after oiling, it is very troublesome for workers to carry it back and forth. Therefore, the structure sets a special base 1 for the hydraulic station. The user can first put it into the installation groove, and then move the structure to a suitable position of the processing machine tool through the cooperation of the handrail 4 and the universal wheel, and make the movable plate 8 contact with the ground by tightening the fastening bolt 23, so that the device is fixed there, and then rotate the crank 19 to make the movable shaft 10 threadedly connected to the threaded rod 9 move horizontally, so that the scissor-type folding frame 18 drives the hydraulic station body 14 to rise to a suitable height, so that the workers can connect the oil pipeline 21 on the hydraulic valve group 13 to the two ends of the telescopic cylinder on the fixture through a hose. This structural setting is convenient for workers to carry the hydraulic station body 14, and also provides convenience for the installation and use of the instrument.

[0035] like Figure 1 As shown, ear plates are fixedly connected to the front and rear side wall surfaces of the base 1 , and fastening bolts 23 are threadedly connected to the surfaces of the ear plates, and a movable plate 8 is provided at the bottom of the fastening bolts 23 .

[0036] By tightening the fastening bolts 23 to allow the movable plate 8 to move downward and contact the ground, the structure can be prevented from moving under the drive of the universal wheels.

[0037] like Figure 1 As shown, a mounting groove is provided on the top surface of the support member 6 , and a hydraulic station body 14 is arranged inside the mounting groove. The hydraulic station body 14 is located on the inner side of the two cover bodies 28 .

[0038] During the use of the pneumatic hydraulic station, it is easy for the harsh processing environment to cause a lot of impurities to adhere to the connection between the hydraulic valve group 13, the oil filling port and the pneumatic pump 11, which not only aggravates the aging of the structure, but also makes it inconvenient for subsequent maintenance. Therefore, the device adds a cover 28 to the hydraulic station body 14. The cover 28 is made of transparent material, and the user can observe the internal pressure gauge value and other conditions from the outside. At the same time, the cover 28 is designed to be an openable and closable structure. The user rotates the knob and transmits kinetic energy to the two sets of mounting frames 26 on the double-headed screw 16 through the engagement of the first bevel gear 24 and the second bevel gear 25, so that the two covers 28 can move toward the middle synchronously, wrapping the hydraulic station body 14 in the center. At the same time, a sponge 27 clamp is set on one side of the cover 28 to clamp the pipe connecting the hydraulic valve group 13 and the telescopic cylinder in the middle, which can effectively prevent external dust and other impurities from entering the cover 28.

[0039] like Figure 1 As shown, the hydraulic station body 14 includes an oil tank 12 and a top cover, the top cover is fixedly connected to the top of the oil tank 12 by bolts, an oil filling port is provided on the surface of the top cover, a sealing cover 20 is threadedly connected to the surface of the oil filling port, and a liquid level gauge is installed on the surface of one side wall of the oil tank 12.

[0040] Oil can be filled into the oil tank 12 through the oil filling port, and the oil level in the oil tank 12 can be observed through the liquid level meter.

[0041] like Figure 1 As shown, a pneumatic pump 11 and a hydraulic valve group 13 are respectively installed on the left and right sides of the surface of the top cover, and an oil pipeline 21 is arranged on the surface of the hydraulic valve group 13 . The oil pipeline 21 is located between the two sponges 27 .

[0042] When in use, the oil pipeline 21 is connected to a corresponding telescopic cylinder or the like through a hose. At this time, the oil pipeline 21 is clamped between two sponges 27 , which can prevent external dust from entering the cover body 28 .

[0043] like Figure 1 As shown, the cover body 28 is made of transparent material, and the transmission rod passes through the side wall surface of the support member 6 and is connected to a knob.

[0044] The cover body 28 is made of a transparent material, which makes it convenient for the user to observe the working condition of the internal instrument. A knob is installed on one side of the transmission rod, which is conducive to the user to quickly adjust the opening and closing condition of the cover body 28.

[0045] The working principle of a hydraulic pneumatic device fixed base provided by the utility model is as follows:

[0046] First step: At present, when installing a pneumatic hydraulic station near a machine tool or other place, since the machine tool itself is not equipped with a special pneumatic hydraulic station fixing seat, it is not convenient to install the machine body near the cylinder and the fixture. In addition, since the hydraulic station itself has a large mass after oiling, it is very troublesome for workers to carry it back and forth. Therefore, the structure sets a special base 1 for the hydraulic station. The user can first put it into the installation groove, and then move the structure to a suitable position of the processing machine tool through the cooperation of the handrail 4 and the universal wheel, and make the movable plate 8 contact with the ground by tightening the fastening bolt 23, so that the device is fixed here, and then rotate the crank 19 to make the movable shaft 10 threadedly connected to the threaded rod 9 move horizontally, so that the scissor-type folding frame 18 drives the hydraulic station body 14 to rise to a suitable height, so that the workers can connect the oil pipeline 21 on the hydraulic valve group 13 to the two ends of the telescopic cylinder on the fixture through a hose. This structural setting is convenient for workers to carry the hydraulic station body 14, and also provides convenience for the installation and use of the instrument;

[0047] The second step: During the use of the pneumatic hydraulic station, it is easy for the harsh processing environment to cause a lot of impurities to adhere to the connection between the hydraulic valve group 13, the oil filling port and the pneumatic pump 11, which not only aggravates the aging of the structure, but also makes it inconvenient for subsequent maintenance. Therefore, the device adds a cover 28 to the hydraulic station body 14. The cover 28 is made of transparent material, and the user can observe the internal pressure gauge value and other conditions from the outside. At the same time, the cover 28 is designed to be an openable and closable structure. The user rotates the knob and transmits the kinetic energy to the two sets of mounting brackets 26 on the double-headed screw 16 through the meshing of the first bevel gear 24 and the second bevel gear 25, so that the two covers 28 can be The hydraulic station body 14 is wrapped in the center by synchronously moving toward the middle. At the same time, a sponge 27 clamp is set on one side of the cover body 28 to clamp the pipe connecting the hydraulic valve group 13 and the telescopic cylinder in the middle, which can effectively prevent external dust and other impurities from entering the cover body 28. The pneumatic hydraulic station does not rely on the oil pump and the motor to absorb oil. Therefore, the oil temperature is low during operation, and there is no heat generated by the motor. The overall working temperature is not high and is close to the indoor temperature, so that the structure can operate normally inside the cover body 28 without worrying about heat dissipation. If the temperature of the working environment in the factory is high, for safety reasons, the user can install a cooling fan on the surface of the cover body.
