Description

Technical Field

[0001] The present invention belongs to the technical field of bearing seats, and more specifically, particularly relates to a new structure heat dissipation bearing seat with an anti-rotation function. Background Art

[0002] The bearing seat has the characteristics of compact structure, sensitive rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat. When the bearing seat is in use, if the mold temperature is too high, it is easy to cause cracks to appear on the surface of the mold core early. Some bearing seats even have large-scale cracks before more than 2000 molds. Therefore, a relative cooling step should be performed when the bearing seat is in use to increase its service life.

[0003] Similar to the current bearing seat, there are still the following deficiencies:

[0004] Currently, most bearing seats use water cooling to dissipate heat. However, the temperature of the circulating water in the water cooling system increases and semi-boiling occurs, which weakens the cooling effect of the circulating water. In addition, current bearings rotate during use and cannot limit the bearings from rotating in one direction.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a new structure heat dissipation bearing seat with anti-rotation function is provided, in order to achieve a more practical purpose. Summary of the invention

[0006] The purpose and effect of the new structure heat dissipation bearing seat with anti-rotation function of the present invention are achieved by the following specific technical means:

[0007] A new structure heat dissipation bearing seat with an anti-rotation function includes a base; the middle position of the top of the base is fixedly connected to the middle position of the bottom of the limiting frame, the limiting frame and the base together form a T shape, the upper and lower ends of the limiting frame are provided with slide rails, the top of the limiting frame is provided with a circulation pipe, the middle position of the upper end of the circulation pipe is provided with a circulation pump, the middle position of the limiting frame is slidably connected to the bearing bracket, the middle position of the bearing bracket is provided with a bearing body, the middle position of the bearing body is rotatably connected to a plug rod, a ratchet is provided at the left side of the plug rod, and a hexagonal groove is provided at the left side of the ratchet, and the front end of the limiting frame is rotatably connected to an adjusting screw A threaded handle rod is provided with a threaded hole in the middle position of the front end of the bearing bracket, and a through hole is provided at the side position of the bearing bracket. The threaded hole at the front end of the bearing bracket is rotatably connected to the rear end position of the adjusting threaded handle rod; the base position is fixed in the required position area, and when it is necessary to calibrate the front and rear position distance of the bearing body set in the middle of the bearing bracket, the adjusting threaded handle rod is rotated, and according to the cooperation between the adjusting threaded handle rod and the threaded hole at the front end of the bearing bracket, the bearing bracket is driven to slide in the middle position inside the limiting frame, thereby achieving the effect of adjusting the front and rear position of the bearing body. When used, it can avoid disassembling the base to adjust the position of the bearing body itself.

[0008] Optionally, the lower left side of the bearing bracket is fixedly connected to the right end surface of the extension seat, the left front end position of the top end surface of the extension seat is fixedly connected to a limiting plate, the upper end position of the limiting plate is provided with a corrugated circular groove, and the limiting plate is located directly to the left of the insertion rod.

[0009] Optionally, a docking frame is fixedly connected to the right rear end position of the top end surface of the extension seat, and the docking frame is located at the rear end position of the pawl. The pawl is rotatably connected to the upper front end position of the docking frame, and the front end position of the pawl is meshed with the rear end position of the ratchet. When the insertion rod in the bearing body rotates, the insertion rod will drive the ratchet to rotate forward. When the insertion rod is subjected to force and rotates in the opposite direction, the pawl meshed at the rear end of the ratchet will limit the position of the ratchet, thereby preventing the ratchet from rotating in the opposite direction.

[0010] Optionally, an inclined skateboard seat is provided at the top of the docking frame, a slide rail is provided at the front end of the skateboard seat, a fixed block is fixedly connected to the rear of the top of the skateboard seat, a threaded hole is provided in the middle of the fixed block, and a bolt rod is rotatably connected in the threaded hole of the fixed block.

[0011] Optionally, the lower position of the bolt rod is rotatably connected to the upper position of the adjusting block, a sliding groove is opened at the rear position of the adjusting block, the sliding groove of the adjusting block is engaged with the sliding rail of the slide seat, the lower end position of the adjusting block is connected to the upper end position of the linkage spring plate, and the other end of the linkage spring plate is connected to the pawl.

[0012] Optionally, a driven disk is rotatably connected in the corrugated circular groove of the limit plate, and a hexagonal docking rod is fixedly connected to the right side of the driven disk, and the docking rod is located in the hexagonal groove of the insertion rod. Six speed limiting parts are arranged on the left side of the driven disk, and a spring is provided in the middle position of the six speed limiting parts. The distance between each two adjacent speed limiting parts is the same, and the six speed limiting parts are located in the corrugated circular groove of the limit plate. When the insertion rod rotates, the driven disk is driven to rotate in the corrugated circular groove of the limit plate through the cooperation of the docking rod. When the docking rod rotates too fast, the six speed limiting parts of the driven disk are extended by the spring in the middle to contact the inner wall position of the corrugated circular groove of the limit plate, and then the driven disk is slowed down by the friction between the outer ends of the six speed limiting parts and the corrugated circular groove of the limit plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the bearing bracket needs to be cooled, cooling oil is first injected into the circulation pipe. Through the super heat conduction ability of the cooling oil, its own lower temperature is transferred to the upper end position of the limiting frame, and then the limiting frame diffuses the temperature as a whole, so that the bearing bracket sliding in the middle position inside the limiting frame is subjected to the cooling step, thereby improving the heat dissipation capacity of the bearing bracket. After starting the circulation pump, the cooling oil in the circulation pipe is driven to circulate. Combined with the characteristics of the cooling oil in the circulation pipe, compared with the traditional cooling water supply, it will not be semi-boiling when the temperature rises, affecting the circulation in the circulation pipe.

[0015] In addition, the base is fixed in the desired position area. When it is necessary to calibrate the front and rear distance of the bearing body set in the middle of the bearing bracket, the bearing bracket is driven to slide in the middle position inside the limit frame according to the cooperation between the adjusting threaded handle and the threaded hole at the front end of the bearing bracket, thereby achieving the effect of adjusting the front and rear position of the bearing body. When in use, it is possible to avoid disassembling the base to adjust the position of the bearing body itself.

[0016] In addition, when the rod in the bearing body rotates, the rod will drive the ratchet to rotate in the forward direction. When the rod is subjected to force and rotates in the reverse direction, the pawl engaged at the rear end of the ratchet will limit the position of the ratchet, thereby preventing the ratchet from rotating in the reverse direction, so that the rod can only rotate in one direction, preventing the bearing body from rotating.

[0017] In addition, when the insertion rod in the bearing body needs to be rotated in the opposite direction, the bolt rod needs to be rotated manually, and the position of the bolt rod in the threaded hole of the fixing block is adjusted by cooperating with the bolt rod and the threaded hole of the fixing block. When the bolt rod is adjusted to the oblique upward position, the rear of the adjustment block is restricted by its own sliding groove and moves to the rearward and upward position on the front end slide rail of the slide plate seat. When the adjustment block moves rearward and upward, the pawl is pulled by the linkage spring plate, so that the pawl is lifted upward, and the pawl is not in contact with the ratchet. When the pawl does not restrict the ratchet, the insertion rod can be rotated in two directions.

[0018] In addition, when the insertion rod rotates, the cooperation of the docking rod drives the driven plate to rotate in the corrugated circular groove of the limit plate. When the docking rod rotates too fast, the six speed limiting parts of the driven plate are extended through the middle spring to contact the inner wall position of the corrugated circular groove of the limit plate, and then the driven plate is slowed down by the friction between the outer ends of the six speed limiting parts and the corrugated circular groove of the limit plate, thereby preventing the insertion rod from rotating too fast in the bearing body and causing the bearing body to overheat.

[0038] When in use: first assemble the entire device in combination with the assembly steps of the embodiment. When it is necessary to cool the bearing bracket 2, first inject cooling oil into the circulation pipe 103. Through the super heat conduction ability of the cooling oil, its own lower temperature is transferred to the upper end position of the limiting frame 101, and then the limiting frame 101 diffuses the temperature as a whole, so that the bearing bracket 2 sliding in the middle position inside the limiting frame 101 is subjected to the cooling step, thereby improving the heat dissipation capacity of the bearing bracket 2. After starting the circulation pump 104, the cooling oil in the circulation pipe 103 is driven to circulate. Combined with the characteristics of the cooling oil in the circulation pipe 103, compared with the traditional cooling water supply, it will not be semi-boiling when the temperature rises, affecting the circulation in the circulation pipe 103.

[0040] Based on the new structure heat dissipation bearing seat with anti-rotation function provided by the first embodiment, the bearing bracket 2 is put into use after the position is fixed. When adjusting the overall position of the bearing bracket 2, it is necessary to perform disassembly and installation steps on the position of the bearing bracket 2. If the hole opening at the installation position of the bearing seat is not accurate, the normal installation of the bearing seat is affected, and it is necessary to re-drill the installation position to improve the relative installation position.

[0042] The base 1 is fixed in the desired position area. When it is necessary to calibrate the front and rear distance of the bearing body 201 set in the middle of the bearing bracket 2, the adjusting threaded handle 102 is rotated. According to the cooperation between the adjusting threaded handle 102 and the threaded hole at the front end of the bearing bracket 2, the bearing bracket 2 is driven to slide in the middle position inside the limiting frame 101, thereby achieving the effect of adjusting the front and rear position of the bearing body 201. When in use, it is possible to avoid disassembling the base 1 to adjust the position of the bearing body 201 itself.

[0043] Embodiment three:

[0044] Based on the new structure heat dissipation bearing seat with anti-rotation function provided by the first embodiment, the bearing may rotate when it is put into use. Therefore, when the bearing is installed in the bearing seat and used, it will drive the rotating rod located in the bearing to rotate forward and reverse. Therefore, the new structure heat dissipation bearing seat with anti-rotation function includes: an extension seat 3; a docking frame 302 is fixedly connected to the right rear end position of the top end surface of the extension seat 3, the docking frame 302 is located at the rear end position of the pawl 303, and the pawl 303 is rotatably connected to the upper front end position of the docking frame 302, and the front end position of the pawl 303 is meshed with the rear end position of the ratchet 203.

[0047] When the insertion rod 202 in the bearing body 201 rotates, the insertion rod 202 will drive the ratchet 203 to rotate in the forward direction. When the insertion rod 202 is subjected to force and rotates in the reverse direction, the pawl 303 engaged at the rear end of the ratchet 203 will limit the position of the ratchet 203, thereby preventing the ratchet 203 from rotating in the reverse direction, so that the insertion rod 202 can only rotate in one direction, preventing the bearing body 201 from rotating.

[0048] On the other hand, when the insertion rod 202 in the bearing body 201 needs to be rotated in the opposite direction, the bolt rod 402 needs to be rotated manually, and the position of the bolt rod 402 in the threaded hole of the fixing block 401 is adjusted by cooperating with the bolt rod 402 and the threaded hole of the fixing block 401. When the bolt rod 402 is adjusted to the oblique upward position, the rear of the adjusting block 403 is restricted by its own sliding groove and moves to the rearward and upward position on the front end slide rail of the sliding plate seat 4. When the adjusting block 403 moves rearward and upward, the pawl 303 is pulled by the linkage spring plate 404, so that the pawl 303 is lifted upward, and then the pawl 303 is not in contact with the ratchet 203.

[0050] Based on the new structure heat dissipation bearing seat with anti-rotation function provided by the first embodiment, when the insertion rod 202 in the bearing body 201 rotates at a high speed, the friction inside the bearing body 201 itself will cause heat generation, and thus the new structure heat dissipation bearing seat with anti-rotation function includes: a driven disk 5; a hexagonal docking rod 502 is fixedly connected to the right side of the driven disk 5, and the docking rod 502 is located in the hexagonal groove of the insertion rod 202.

[0051] In addition, six speed limiting members 501 are arranged on the left side of the driven disk 5 . A spring is arranged in the middle of the six speed limiting members 501 . The distance between every two adjacent speed limiting members 501 is the same. The six speed limiting members 501 are located in the corrugated circular groove of the limiting plate 301 .

[0052] When the insertion rod 202 rotates, the driven disk 5 is driven to rotate in the corrugated circular groove of the limit plate 301 through the cooperation of the docking rod 502. When the docking rod 502 rotates too fast, the six speed limiting parts 501 of the driven disk 5 are extended through the middle spring to contact the inner wall position of the corrugated circular groove of the limit plate 301, and then the driven disk 5 is slowed down by the friction between the outer ends of the six speed limiting parts 501 and the corrugated circular groove of the limit plate 301, so as to prevent the insertion rod 202 from rotating too fast in the bearing body 201, causing the bearing body 201 to overheat.
