Description

Technical Field

[0001] The present invention relates to the field of grinding equipment, and particularly to a precision finishing grinding equipment for the outer conical surface of a tool rest cone. Background Art

[0002] Vertical lathes are mainly used for machining large and heavy workpieces with large diameters and short lengths, as well as workpieces that are not easily clamped on horizontal lathes. The tool rest cone of a vertical lathe is a part used to install between the tool rest of the vertical lathe and the machine tool ram.

[0003] After the machining of the tool rest cone of a vertical lathe is completed, there will inevitably be certain manufacturing tolerances. In the prior art, the conventional precision finishing method for the tool rest cone is to fix the cone on a rotating shaft, use a grinding wheel to grind the outer conical surface of the cone, and move the grinding wheel in a circular motion along the generatrix direction of the cone, and intermittently measure the size of the cone until the size of the cone meets the usage requirements, then the precision finishing grinding of the cone can be completed.

[0004] In view of the above related technologies, during the precision finishing grinding of the outer conical surface of the tool rest cone by the existing grinding equipment, it is necessary to precisely control the angle and movement trajectory of the grinding wheel to achieve a high grinding quality. Moreover, the method of intermittently measuring the tool rest cone to determine whether the grinding is completed not only takes time and effort, but also is difficult to stop the grinding work in a timely manner, and it is easy to over-grind the cone. In summary, it is relatively difficult for the existing grinding device to perform precision finishing grinding on the outer conical surface of the tool rest cone. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a precision finishing grinding equipment for the outer conical surface of a tool rest cone to solve the technical problem that it is relatively difficult for the existing grinding device to perform precision finishing grinding on the outer conical surface of the tool rest cone.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A precision finishing grinding equipment for the outer conical surface of a tool rest cone, including a machine case. A support frame is installed inside the machine case. A horizontal grinding belt is transversely arranged on the support frame. The top surface of the grinding belt is used to contact the outer conical surface of the tool rest cone and is driven by a driving component inside the machine case to move in a cycle. It also includes a sliding table. An expansion rod for longitudinally pushing the sliding table to move is fixed on the machine case. A fixing component for fixing the tool rest cone is installed on the sliding table.

[0007] By adopting the above technical solution, the movement of the sliding table enables the grinding belt to evenly grind the surface of the cone. When the grinding belt no longer has relative friction with the cone, the precision finishing grinding of the outer conical surface of the cone can be completed. Moreover, the precision finishing grinding of multiple cones can be carried out simultaneously, and the high-quality precision finishing grinding work of the outer conical surface of the cone can be easily completed.

[0008] The present invention is further configured such that one end of the sliding table is fixedly connected to a fixed table, a second vertical adjustment table is slidably connected to the fixed table in the vertical direction, a horizontal adjustment table is slidably connected to the other end of the sliding table in the horizontal direction, a first vertical adjustment table is slidably connected to the horizontal adjustment table in the vertical direction, a plurality of first top cones are rotatably connected to the first vertical adjustment table at intervals, a plurality of second top cones are rotatably connected to the second vertical adjustment table at intervals, and the first top cones and the second top cones respectively press against both ends of the tool holder cone.

[0009] Preferably, the positions of the first top cone and the second top cone are adjusted by an adjustment mechanism, and when the outer conical surface of the tool holder cone contacts the grinding belt, the tool holder cone is inclined at an ideal angle.

[0010] The present invention is further configured such that a fixed plate is fixedly connected inside the chassis, a screw rod is rotatably connected to the fixed plate, a driving column is sleeved outside the screw rod, a through hole for passing through the screw rod is provided at the end of the driving column, and the end of the driving column away from the screw rod is transmitted to the tool holder cone through a transmission joint. When the driving column and the screw rod move relative to each other along their own axis directions, the tool holder cone can be driven to rotate.

[0011] Preferably, during the process of the sliding table being pushed by the telescopic rod, the driving column and the screw rod move relative to each other in the axial direction. Since the screw rod cannot rotate along its own axis, when the driving shaft rotates along its own axis, the second top cone is driven to rotate through the transmission joint, and then the tool holder cone is driven to rotate.

[0012] The present invention is further configured such that empty slots are provided at intervals on the support frame, two moving blocks are slidably connected horizontally in the empty slots, a limiting strip is fixedly connected to the middle of the empty slots, the limiting strip is located directly below the connection line of the ends of the first top cone and the second top cone, the top surfaces of the moving blocks are flush with the top surface of the support frame, and the two moving blocks in the empty slots can move towards each other and contact each other after being limited by the limiting strip.

[0013] Preferably, during the initial grinding process of the tool holder cone, the two moving blocks in the empty slots move away from each other, so that the grinding belt contacted by the tool holder cone can be pressed down to generate deformation, enabling the tool holder cone to be in an ideal taper inclination state. As the taper grinding work progresses, the outer conical surface of the tool holder cone gradually wears and tends to the ideal taper state, and the moving blocks move towards each other and contact, making the grinding belt unable to be pressed down and deformed, which is beneficial for further precision grinding of the tool holder cone.

[0014] The present invention is further configured such that a first adjusting screw passes through the middle of the horizontal adjusting table. The first adjusting screw is used to control the sliding position of the horizontal adjusting table. A second adjusting screw rotatably connected to the horizontal adjusting table passes through the first vertical adjusting table. The second adjusting screw is used to control the sliding position of the first vertical adjusting table. A third adjusting screw rotatably connected to the sliding table passes through the second vertical adjusting table. The third adjusting screw is used to control the sliding position of the second vertical adjusting table.

[0015] Preferably, by rotating the respective corresponding adjusting screws, the position adjustment of each adjusting table can be achieved.

[0016] The present invention is further configured such that the driving column is connected to the second top cone through a transmission joint. The first top cone and the second top cone can rotate about the axis of the tool holder cone and can respectively rotate about the rotating shafts connecting the first vertical adjusting table and the second vertical adjusting table. The axis of the spiral rod rotatably connected to the fixing plate is parallel to the axis of the first top cone rotatably connected to the second vertical adjusting table.

[0017] Preferably, during the process of the driving column telescoping relative to the spiral rod, it rotates itself to drive the tool holder cone to rotate.

[0018] The present invention is further configured such that the sum of the stroke of the telescopic rod and the width of the grinding belt is greater than the length of the generatrix of the outer conical surface of the tool holder cone.

[0019] Preferably, it is avoided that there is an area where the tool holder cone cannot be ground.

[0020] The present invention is further configured such that the height of the first top cone is higher than that of the second top cone. The first top cone extends along its own axis direction, and the first vertical adjusting table does not contact the tool holder cone.

[0021] Preferably, it is avoided that interference occurs between the tool holder cone and the first vertical adjusting table.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. By arranging a horizontal grinding belt on the chassis, the present invention uses a fixing structure to fix the cone obliquely, makes the generatrix of the cone flush with and in contact with the grinding belt, and after finely adjusting the position of the fixing structure, the cone is in an inclined state with an ideal taper. By moving the sliding table, the grinding belt evenly grinds the surface of the cone. When the grinding belt no longer has relative friction with the cone, the fine finishing grinding of the outer conical surface of the cone can be completed. And at the same time, the fine finishing grinding of multiple cones can be carried out, easily completing the high-quality fine finishing grinding work of the outer conical surface of the cone.

[0024] 2. The present invention realizes the relative movement between the cone and the grinding belt by pushing the sliding table through the telescopic rod. During the sliding of the sliding table, another set of driving structures fixedly connected to the chassis utilize the relative change in the distance between the sliding table and the driving structures on the chassis to realize the positive and reverse cyclic rotation of the cone, improving the grinding quality of the outer conical surface of the cone.

[0025] 3. The present invention sets an empty groove inside the support frame for supporting the grinding belt, with the empty groove located below the generatrix of the cone. During the initial grinding of the cone, the two moving blocks inside the empty groove move away from each other, causing the grinding belt contacted by the cone to be pressed down and deformed, enabling the cone to be in an ideal tapered state. As the grinding work of the cone progresses, the outer conical surface of the cone gradually wears and tends towards the ideal tapered state, and the moving blocks move towards each other and contact, making it impossible for the grinding belt to be pressed down and deformed, which is beneficial for the further precision grinding of the cone.

[0026] 4. The present invention uses a top cone to cooperate with the holes at both ends of the cone at both ends of the cone to achieve rapid positioning and fixation of the cone, enabling the angles of multiple cones in the grinding equipment to be quickly unified and realizing the stable fixation of the cone, preventing the cone from displacing during the grinding process, and further improving the precision grinding quality of the cone.

Detailed implementation manners

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0042] The first embodiment:

[0043] A precision finishing and grinding device for the outer conical surface of a tool rest cone, please refer to Figures 1-11 , including a chassis 1. Transparent observation windows are provided on both sides of the chassis 1 to facilitate observing the positions of the fixed structures inside the chassis 1. A support frame 2 is installed inside the chassis 1. A horizontal grinding belt 3 is transversely arranged on the support frame 2. Specifically, a tensioning wheel for tensioning the grinding belt 3 and a driving wheel for driving the grinding belt 3 to move in a cycle are also provided inside the chassis 1. The cyclic movement of the grinding belt 3 is a well-known technology to those skilled in the art and will not be elaborated here. The top surface of the grinding belt 3 is used to contact the outer conical surface of the tool rest cone and is driven to move in a cycle by a driving component inside the chassis 1.

[0044] It further includes a sliding table 4. A telescopic rod 18 for longitudinally pushing the sliding table 4 to move is fixed on the chassis 1. A fixing assembly for fixing the tool holder cone is installed on the sliding table 4. Specifically, the telescopic rod 18 can be an electric telescopic rod, a hydraulic telescopic rod, etc. In this embodiment, there are two telescopic rods 18 in total, and both telescopic rods 18 are electric telescopic rods. The telescopic rod 18 reciprocally expands and contracts in the working state, enabling the outer conical surface of the tool holder cone to reciprocally move relative to the width direction of the grinding belt, ensuring the uniformity of the wear degree of the grinding belt 3, and at the same time, it can further improve the uniformity of the grinding of the tool holder cone.

[0045] In the above embodiment, specifically, please refer to Figures 4-7 , one end of the sliding table 4 is fixedly connected to a fixed table 7. A second vertical adjustment table 8 is slidably connected to the fixed table 7 in the vertical direction. The other end of the sliding table 4 is slidably connected to a horizontal adjustment table 5 in the horizontal direction. A first vertical adjustment table 6 is slidably connected to the horizontal adjustment table 5 in the vertical direction. A plurality of first top cones 12 are rotatably connected to the first vertical adjustment table 6 at intervals. A plurality of second top cones 13 are rotatably connected to the second vertical adjustment table 8 at intervals. The first top cones 12 and the second top cones 13 are used to cooperate with the holes at both ends of the tool holder cone to conveniently position the tool holder cone.

[0046] Specifically, in this embodiment, the number of both the first top cones 12 and the second top cones 13 is four. The first top cones 12 and the second top cones 13 respectively press against both ends of the tool holder cone. The positions of the first top cones 12 and the second top cones 13 are adjusted by an adjustment mechanism. When the outer conical surface of the tool holder cone contacts the grinding belt, the tool holder cone is inclined at an angle of an ideal taper.

[0047] The second embodiment:

[0048] A fine finishing grinding device for the outer conical surface of a tool holder cone, please refer to Figures 1-11 , a fixing plate 17 is fixedly connected inside the chassis 1. A screw rod 16 is rotatably connected to the fixing plate 17. A hollow driving column 15 is sleeved outside the screw rod 16. A through hole 1501 for passing through the screw rod 16 is provided at the end of the driving column 15. Specifically, the pitch of the screw rod 16 is relatively large and it cannot rotate along its own axis. The through hole 1501 of the driving column 15 contacts the surface of the screw rod 16. When the driving column 15 and the screw rod 16 have a relative sliding along the axial direction, the driving column 15 can achieve self-rotation along its own axis.

[0049] Furthermore, one end of the driving column 15 away from the screw rod 16 is transmitted to the tool rest cone through the transmission joint 14. Specifically, the transmission joint 14 can adaptively adjust its own angle to provide stable transmission between the driving column 15 and the second top cone 13. When the driving column 15 and the screw rod 16 move relative to each other along their own axis directions, the tool rest cone can be driven to rotate. During the process that the sliding table 4 is pushed by the telescopic rod 18, relative movement occurs between the driving column 15 and the screw rod 16 in the axis direction. Since the screw rod 16 cannot rotate along its own axis, when the driving column 15 rotates along its own axis, the second top cone 13 is driven to rotate through the transmission of the transmission joint 14, thereby driving the tool rest cone to rotate.

[0050] In the above embodiment, specifically, please refer to Figures 4-7 , a first adjusting screw rod 9 passes through the middle of the horizontal adjusting table 5. The first adjusting screw rod 9 is used to control the sliding position of the horizontal adjusting table 5. Specifically, rotating the first adjusting screw rod 9 can make the horizontal adjusting table 5 move horizontally. A second adjusting screw rod 10 is rotatably connected to the horizontal adjusting table 5 and passes through the first vertical adjusting table 6. The second adjusting screw rod 10 is used to control the sliding position of the first vertical adjusting table 6. Specifically, rotating the second adjusting screw rod 10 can adjust the height of the first vertical adjusting table 6 in the vertical direction. A third adjusting screw rod 11 is rotatably connected to the sliding table 4 and passes through the second vertical adjusting table 8. The third adjusting screw rod 11 is used to control the sliding position of the second vertical adjusting table 8. Specifically, rotating the third adjusting screw rod 11 can adjust the height of the second vertical adjusting table 8. Rotating each corresponding adjusting screw rod can realize the position adjustment of each adjusting table.

[0051] In the above embodiment, specifically, please refer to Figures 2-5 , Figures 10-11 , the driving column 15 is connected to the second top cone 13 through the transmission joint 14. The first top cone 12 and the second top cone 13 can rotate with the axis of the tool rest cone as the axis, and can respectively rotate with the rotating shafts connecting the first vertical adjusting table 6 and the second vertical adjusting table 8. The axis of the screw rod 16 rotatably connected to the fixed plate 17 is parallel to the axis of the first top cone 12 rotatably connected to the second vertical adjusting table 8. During the process of the driving column 15 telescoping relative to the screw rod 16, it rotates itself to drive the tool rest cone to rotate.

[0052] In the above embodiment, specifically, please refer to Figures 1-7 , the sum of the stroke of the telescopic rod 18 and the width of the grinding belt 3 is greater than the generatrix length of the outer conical surface of the tool rest cone, so as to avoid the area where the tool rest cone cannot be ground and realize the full grinding of the outer conical surface of the cone 19.

[0053] Further, the height of the first top cone 12 is higher than that of the second top cone 13, so that the cone 19 is in an inclined state when fixed. The first top cone 12 extends along its own axis. The first vertical adjustment table 6 does not contact the tool rest cone, avoiding interference between the tool rest cone and the first vertical adjustment table 6.

[0054] The third embodiment:

[0055] For a fine grinding equipment for the outer conical surface of a tool rest cone, please refer to Figures 1-9 , there are empty slots 201 arranged at intervals on the support frame 2. Two moving blocks 203 are horizontally slidably connected in the empty slots 201. Specifically, the moving blocks 203 are moved by a driving structure arranged in the support frame 2. In this embodiment, a telescopic mechanism for controlling the movement of the moving blocks 203 is installed in the support frame 2, and a telescopic cylinder can be specifically adopted.

[0056] Further, a limiting strip 202 is fixedly connected to the middle of the empty slot 201. The limiting strip 202 is located directly below the connecting line of the ends of the first top cone 12 and the second top cone 13. The limiting strip 202 can prevent the moving block 203 from moving excessively and play a limiting role on the moving block 203. The top surface of the moving block 203 is flush with the top surface of the support frame 2. The two moving blocks 203 in the empty slot 201 can move towards each other and contact each other after being limited by the limiting strip 202.

[0057] Specifically, during the initial grinding of the tool rest cone, the two moving blocks 203 in the empty slot 201 move away from each other, so that the grinding belt 3 contacted by the tool rest cone can be pressed down and deformed, enabling the tool rest cone to be in an ideal taper inclined state. As the cone grinding work progresses, the outer conical surface of the tool rest cone gradually wears and tends to the ideal taper state, and the moving blocks 203 move towards each other and contact, making the grinding belt 3 unable to be pressed down and deformed, which is beneficial for further fine grinding of the tool rest cone.

[0058] When the grinding equipment grinds the outer conical surface of the tool rest cone: place the top of the cone 19 downward and inclined on the grinding belt 3, adjust the height of the second vertical adjustment table 8 to insert the second top cone 13 into the hole at the top of the cone 19, then adjust the horizontal adjustment table 5 towards the cone 19, and adjust the height of the first vertical adjustment table 6 to insert the first top cone 12 into the hole at the bottom of the cone 19. At this time, the outer conical surface of the cone 19 contacts the grinding belt 3. Looking at the inclination angles of the first top cone 12 and the second top cone 13 and the distance between them from the side of the chassis 1, finely adjust the positions of the first vertical adjustment table 6, the second vertical adjustment table 8, and the horizontal adjustment table 5 to make the cone 19 in an ideal taper inclined state. At this time, the two moving blocks 203 below the cone 19 are in a state of moving away from each other, and the cone 19 can press down the grinding belt 3 to cause the grinding belt 3 to undergo slight deformation;

[0059] Then, start the abrasive belt 3 and the telescopic rod 18. When the telescopic rod 18 reciprocates telescopically, the driving column 15 also reciprocates telescopically relative to the screw rod 16. The through-hole 1501 of the driving column 15 contacts the surface of the screw rod 16 to make the driving column 15 rotate, thereby realizing the reciprocating positive and negative rotation of the cone 19, fully grinding the outer conical surface of the cone 19, effectively improving the grinding quality of the outer conical surface of the cone 19. As the grinding work of the outer conical surface of the cone 19 progresses, the tolerance part existing in the cone 19 has been ground and removed. At this time, the cone 19 is in a state where the abrasive belt 3 is no longer pressed down or is pressed down more slightly. At this time, the two moving blocks 203 move towards each other and fit together, making the abrasive belt 3 below the cone 19 level with the abrasive belt 3 in other parts of the support frame 2, and further performing fine grinding on the cone 19 until the abrasive belt 3 no longer rubs against the cone 19, then the fine grinding work of the cone 19 can be completed.

[0060] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and are not limitations of the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
