Description

Technical Field

[0001] The invention relates to the technical field of end gear disc processing, and in particular to a cooling device for end gear disc end surface grinding equipment. Background Art

[0002] The grinding process of the end gear disc uses a thinner metal layer than the metal layer cut in ordinary cutting processes such as turning and milling. As a result, about 60%-95% of the heat is directly transferred to the workpiece during the grinding process, and less than 1% of the heat is carried away by the chips generated by grinding. The grinding position on the end gear disc will produce local high temperature, and the residual heat will form a large temperature gradient on the surface of the grinding part of the end gear disc. In conventional grinding operations, cutting fluid is used to cool the grinding part of the end gear disc, and the rotation speed of the grinding wheel needs to be limited, resulting in a long time for the end face grinding of the end gear disc.

[0003] After searching: the Chinese patent application number is "CN202311007928.8", which discloses a large-size end gear disc end face grinding equipment, including the following structures: an annular slide rail, the top of the annular slide rail is symmetrically and movably connected with a pulley about its center; a central base; a central mounting seat, the bottom of the central mounting seat is fixedly connected to the bottom of the inner wall of the central base; a guide seat; in the immersion tank of the central base, the position of the guide pipe in the immersion tank is changed in coordination with the annular slide rail, the pulley and the robotic arm, wherein the guide pipe cooperates with the cutting fluid circulation equipment to complete the circulation of the cutting fluid in the immersion tank and the iron chip filtering treatment, the immersion processing operation of the blank gear ring, and the reduction of the intensity of heat diffusion at the grinding point.

[0004] The inventors found the following problems in the prior art during the implementation of the present invention:

[0005] In the prior art, the end gear disc is immersed in cutting fluid for cooling. However, the temperature of the cutting fluid will rise when the cutting fluid is used for a long time. Then, immersing the newly processed end gear disc in the heated cutting fluid will affect the cooling effect of the cutting fluid on the end gear disc.

[0006] Therefore, a cooling device for end tooth disc end surface grinding equipment is provided which can drive the piston to rise during use to make the cutting fluid in the liquid storage barrel rise so that the end tooth disc is completely immersed in the cutting fluid, and intermittent heat exchange is performed on the end tooth disc to achieve repeated cooling.

[0034] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0035] like Figure 1-4 As shown, the present invention provides a cooling device for end gear disc end surface grinding equipment, the device comprising: a liquid storage barrel 1, a processing platform 2 and a cooling mechanism;

[0036] The open mouth of the liquid storage barrel 1 storing cutting fluid is horizontally fixed with a processing platform 2 partially immersed in the cutting fluid through at least two cross bars, and the upper end of the processing platform 2 is fixed with a clamping mechanism to fix the end gear disc 15. The cooling mechanism includes: a cooling container 5 coaxially fixed at the port of the liquid storage barrel 1, a first buffer 6 and a second buffer 7 coaxially fixed in the cooling container 5 from the inside to the outside and in an annular shape, and a plurality of semiconductor refrigerators 8 fixed on the bottom end of the cooling container 5 and with the cooling surface against the cooling container 5; wherein,

[0037] A one-way liquid inlet pipe 16 is fixedly installed at the bottom of the cooling container 5, and the free end of the one-way liquid inlet pipe 16 is connected and fixed to the liquid storage barrel 1. The liquid storage barrel 1 located below the processing platform 2 has a piston 10 horizontally and liftably installed inside it that can push the cutting fluid up so that the cutting fluid overflows from its open mouth and flows into the cooling container 5.

[0038] In the above scheme, if Figure 1 and Figure 2 As shown, in order from inside to outside, a cooling area No. 1 is formed between the No. 1 buffer 6 and the liquid storage barrel 1, a cooling area No. 2 is formed between the No. 1 buffer 6 and the No. 2 buffer 7, and a cooling area No. 3 is formed between the No. 2 buffer 7 and the inner wall of the cooling container 5, and the bottom end of the cooling container 5 located in each cooling area is fixedly provided with a plurality of semiconductor refrigerators 8 at equal intervals along its circumferential direction, and the cooling surface of each semiconductor refrigerator 8 is against the bottom end of the cooling container 5, so that the cutting fluid in each cooling area can be cooled and cooled down by a plurality of semiconductor refrigerators 8.

[0039] When in use, the piston 10 is intermittently driven to rise in the vertical direction to drive the cutting fluid in the liquid storage barrel 1 to rise until part of the cutting fluid in the liquid storage barrel 1 overflows from its open mouth and flows into the cooling container 5. In the process of the cutting fluid overflowing from the open mouth of the liquid storage barrel 1, the processing platform 2 horizontally fixed at the open mouth of the liquid storage barrel 1 and the end gear disc 15 fixed on the processing platform 2 can be completely immersed in the cutting fluid to cool the end gear disc 15 and the processing platform 2. The cutting fluid overflowing from the liquid storage barrel 1 into the cooling container 5 can flow back to the liquid storage barrel 1 again through the one-way liquid inlet pipe 16 after cooling, so that the cutting fluid can be recycled and the cost can be saved.

[0040] When part of the cutting fluid in the liquid storage barrel 1 overflows from the open mouth and flows into the cooling container 5, the cutting fluid first flows from the open mouth of the liquid storage barrel 1 into the No. 1 cooling area formed between the No. 1 buffer 6 and the liquid storage barrel 1 for primary cooling, and when the liquid level of the cutting fluid in the No. 1 cooling area rises to the height of the No. 1 buffer 6, the cutting fluid in the No. 1 cooling area overflows the No. 1 buffer 6 and enters the No. 2 cooling area formed between the No. 1 buffer 6 and the No. 2 buffer 7 for secondary cooling. Similarly, when the liquid level of the cutting fluid in the No. 2 cooling area rises to the height of the No. 2 buffer 7, the cutting fluid in the No. 2 cooling area overflows the No. 2 buffer 7 and enters the No. 3 cooling area formed between the No. 2 buffer 7 and the inner wall of the cooling container 5 for tertiary cooling. After multiple coolings, the cutting fluid in the No. 3 cooling area returns to the liquid storage barrel 1 through the one-way liquid inlet pipe 16 for reuse.

[0041] Therefore, the used cutting fluid can be subjected to multiple cooling and cooling treatments through the cooling mechanism to improve the cooling effect, so that the cooled cutting fluid can be returned to the fluid storage barrel 1 for continued use.

[0042] In a preferred embodiment of the present invention, the clamping mechanism comprises: a first fixing column 3 and a second fixing column 4; wherein,

[0043] The interior of the processing platform 2 is vertically fixed with at least three No. 1 fixing columns 3 that can pass through the top thereof at equal intervals along its circumferential direction to abut against the outer wall of the end toothed disk 15. The interior of the processing platform 2 is also evenly spaced along its circumferential direction with three No. 2 fixing columns 4 that correspond to the three No. 1 fixing columns 3 one by one and can approach the corresponding No. 1 fixing columns 3 respectively, and the top end portion of each No. 2 fixing column 4 extends from the upper end of the processing platform 2 to abut against the inner wall of the end toothed disk 15. The upper end of the processing platform 2 is evenly provided with strip holes 17 that are connected with the interior thereof and for the three No. 2 fixing columns 4 to pass through.

[0044] In the above scheme, when used, Figure 3 and Figure 4 As shown, the end toothed disc 15 to be processed is horizontally placed on the upper end of the processing platform 2, and the outer wall of the end toothed disc 15 is respectively pressed against all the No. 1 fixing columns 3, and all the No. 2 fixing columns 4 are respectively driven to approach the corresponding No. 1 fixing columns 3 along the corresponding strip holes 17 until the No. 2 fixing columns 4 are pressed against the inner wall of the end toothed disc 15, thereby fixing the end toothed disc 15 horizontally on the processing platform 2.

[0045] In addition, each of the No. 1 fixing column 3 and each of the No. 2 fixing column 4 is provided with a rubber sleeve with a protrusion. The purpose of this is to increase the friction between the No. 1 fixing column 3, the No. 2 fixing column 4 and the end toothed disc 15, so that the end toothed disc 15 is firmly fixed and clamped between the No. 1 fixing column 3 and the No. 2 fixing column 3, so as to improve the stability and reliability of the clamping.

[0046] In a preferred embodiment of the present invention, the clamping mechanism further includes a driving assembly for driving the three No. 2 fixed columns 4 to approach the corresponding No. 1 fixed columns 3, respectively, and the driving assembly includes: a moving block 18, a driving tooth plate 19 and a driving gear 20; wherein,

[0047] On the bottom end of the interior of the processing platform 2, three moving blocks 18 are movably arranged at equal intervals along the circumferential direction thereof, and are respectively approaching the three No. 1 fixed columns 3, and a No. 2 fixed column 4 is vertically fixedly arranged on the upper end of each of the moving blocks 18, and a driving gear plate 19 is horizontally fixedly arranged on one side of each of the moving blocks 18, and a driving gear 20 meshingly connected thereto is horizontally and rotatably arranged inside the processing platform 2 located next to each of the driving gear plates 19.

[0048] In the above scheme, when in use, all the driving gears 20 are rotated to drive all the driving tooth plates 19 meshing with each other to drive all the moving blocks 18 and the No. 2 fixed columns 4 on the moving blocks 18 to move toward the corresponding No. 1 fixed columns 4, so that the end toothed disks horizontally placed on the processing platform 2 are clamped and fixed to prevent them from being offset during the processing and affecting the processing effect.

[0049] In a preferred embodiment of the present invention, the driving assembly further comprises: an electric telescopic rod 21 and a chain 22; wherein,

[0050] Sprockets are coaxially fixed on the central rotating shafts of all the driving gears 20 located above the driving tooth plate 19, and all the sprockets are connected together through an electric telescopic rod 21. An electric telescopic rod 21 parallel to the driving tooth plate 19 is horizontally fixed on the processing platform 2 located next to any one of the driving tooth plates 19, and the telescopic end of the electric telescopic rod 21 is connected to the end of the driving tooth plate 19 through a connecting plate. The top end of the central rotating shaft of any one of the driving gears 20 is coaxially connected to the motor vertically fixed on the processing platform 2 through a coupling.

[0051] In the above scheme, by starting the electric telescopic rod 21 to drive the driving toothed plate 19 fixedly connected thereto to drive the moving block 18 and the No. 2 fixed column 4 fixed thereon to approach the No. 1 fixed column 3, the driving gear 20 meshing with it can be driven to rotate, and in the process of rotation of the driving gear 20, the chain 22 can drive all the remaining driving gears 20 to rotate synchronously, and in the process of rotation, all the remaining driving gears 20 can respectively drive the driving toothed plates 19 meshing with each other to drive the corresponding moving blocks 18 and the No. 2 fixed columns 4 fixed on the moving blocks 18 in the horizontal direction to approach the corresponding No. 1 fixed columns 3.

[0052] Therefore, the driving assembly can synchronously drive all the No. 2 fixing columns 4 to approach their corresponding No. 1 fixing columns 3 , so as to quickly fix the end gear disc 15 horizontally placed on the processing platform 1 .

[0053] In addition, the electric telescopic rod 21 is a cylinder or a servo electric cylinder.

[0054] In a preferred embodiment of the present invention, the device further comprises a lifting structure for driving the piston 10 to intermittently lift and lower in the vertical direction, wherein the lifting mechanism comprises: an incomplete gear 11, a lifting tooth plate 12 and a return spring 13; wherein,

[0055] A power box 9 with a hollow structure inside is coaxially fixed at the bottom end of the liquid storage barrel 1, a lifting gear plate 12 which can extend from its bottom end part into the power box 9 is vertically fixed at the bottom end of the piston 10, and an incomplete gear 11 which can be intermittently meshed with the lifting gear plate 12 is horizontally and rotatably arranged in the power box 9 next to the lifting gear plate 12, and a plurality of return springs 13 are evenly and vertically fixed at the bottom end of the piston 10, and the bottom end of each of the return springs 13 is fixedly arranged on the bottom end of the liquid storage barrel 1.

[0056] In the above scheme, when in use, by driving the incomplete gear 11 to rotate continuously in a certain direction, and during the rotation, it can intermittently engage with the lifting gear plate 12. When the incomplete gear 11 rotates continuously counterclockwise, the incomplete gear 11 is engaged with the lifting gear plate 12, and the lifting gear plate 12 can be driven to push the piston 10 to rise and fall in the vertical direction, so that the multiple return springs 13 are in a stretched state. At the same time, when the piston 10 rises, it can push the cutting fluid in the liquid storage barrel 1 to rise until part of the cutting fluid in the liquid storage barrel 1 overflows from its open mouth and flows into the cooling container 5. In the process of the cutting fluid overflowing from the open mouth of the liquid storage barrel 1, the processing platform 2 horizontally fixed at the open mouth of the liquid storage barrel 1 and the end toothed disc 15 fixed on the processing platform 2 can be completely immersed in the cutting fluid to cool the end toothed disc 15 and the processing platform 2. The cutting fluid overflowing from the liquid storage barrel 1 into the cooling container 5 can flow back into the liquid storage barrel 1 again through the one-way liquid inlet pipe 16 after being cooled, so that the cutting fluid can be recycled and the cost can be saved.

[0057] When the incomplete gear 11 loses its meshing relationship with the lifting gear plate 12, the piston 10 descends to its initial position in the vertical direction under the action of the plurality of return springs 13, so that the processing platform 2 and the end gear disc 15 fixed on the processing platform 2 are exposed above the cutting fluid level, so as to process the end gear disc 15 or take out the processed end gear disc 15.

[0058] In a preferred embodiment of the present invention, two guide rods 14 are spaced apart and vertically fixed at the bottom end of the piston 10 and can partially extend from the bottom end of the liquid storage barrel 1 into the power box 9 .

[0059] In the above solution, two guide holes are vertically penetrated through the bottom end of the liquid storage barrel 1 for the two guide rods 14 to pass through.

[0060] The guide rod 14 and the two guide holes on the bottom end of the liquid storage barrel 1 play a guiding role to ensure that the piston 10 can be lifted and lowered smoothly and reliably in a straight line in the vertical direction.

[0061] In addition, the piston 10 is made of rubber so that there is no gap between the piston 10 and the inner wall of the liquid storage barrel 1 during the lifting process of the piston 10, which can ensure that during the lifting process, the cutting fluid is prevented from flowing into the bottom end of the liquid storage barrel 1 through the gap between the piston 10 and the liquid storage barrel 1.

[0062] In a preferred embodiment of the present invention, a one-way valve 24 is fixedly provided on the one-way liquid inlet pipe 16 .

[0063] In the above scheme, the medium flow direction of the one-way valve 24 is: the medium can only enter the liquid storage barrel 1 from the cooling container 5 through the one-way liquid inlet pipe 16, thereby preventing the piston 10 from pushing the cutting fluid in the liquid storage barrel 1 to rise, so that the cutting fluid can only overflow from the open mouth of the liquid storage barrel and flow into the cooling container 5, rather than the cutting fluid entering the cooling container 5 through the one-way liquid inlet pipe 16 during the rising process.

[0064] In addition, it should be noted that the maximum height to which the piston 10 rises is lower than the height of the connection between the one-way liquid inlet pipe 16 and the liquid storage barrel 1, so as to prevent the liquid from entering the liquid storage barrel 1 located below the piston 10 from the cooling container 5 through the one-way liquid inlet pipe 16 during the rising process of the piston 10.

[0065] In a preferred embodiment of the present invention, guide rails 23 compatible with the three driving tooth plates 19 are horizontally fixedly arranged at equal intervals on the bottom end of the interior of the processing platform 2, and the bottom end of each of the driving tooth plates 19 is partially recessed inward to form a guide groove compatible with the guide rail 23, and each of the driving tooth plates 19 can be slidably assembled on the corresponding guide rail 23 through the guide groove.

[0066] In the above scheme, by the coordinated use of the guide rail 23 and the guide groove of the driving tooth plate 19, it can be ensured that the driving tooth plate 19 can smoothly and reliably drive the second fixed column 4 on the moving block 18 in a straight line toward the corresponding No. 1 fixed column 3 in the horizontal direction to play a guiding role.

[0067] In summary, the cooling device for end face grinding equipment of the end tooth disc provided by the present invention overcomes the problem in the prior art that in the process of cooling the end tooth disc by immersing the end tooth disc in cutting fluid, the temperature of the cutting fluid will increase when used for a long time, and then immersing the newly processed end tooth disc in the heated cutting fluid will affect the cooling effect of the cutting fluid on the end tooth disc.
