Description

Technical Field

[0001] This invention relates to the field of grinding machine tailstock technology, and more particularly to a grinding machine tailstock center alignment adjustment device. Background Technology

[0002] A cam grinding machine mainly includes a clamping mechanism and a grinding mechanism. The clamping mechanism includes a headstock and a tailstock. The headstock is fixedly mounted on the operating table, and the tailstock is adjustable along the length of the operating table. The headstock and tailstock cooperate to clamp the cam shaft. For example, Chinese Patent [Publication No.: CN113618558A] discloses a high-precision, high-speed follower camshaft grinding machine, which details the structure of the cam grinding machine.

[0003] When grinding camshafts, the camshaft is clamped and fixed by the centers of the headstock and tailstock. When the tailstock is disassembled or worn, the centers of the headstock and tailstock are easily misaligned, resulting in deviations in the machined parts. Therefore, an adjustment device is usually added between the tailstock and the worktable to restore the centers of the headstock and tailstock to a straight line.

[0004] However, the existing adjustment device can only adjust the tailstock along the width of the tailstock, and cannot adjust the position of the tailstock in the height direction. Furthermore, it is impossible to observe the coaxiality of the top of the headstock and the top of the tailstock in real time during the adjustment process, resulting in low adjustment efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a grinding machine tailstock center alignment adjustment device to solve the problems in the prior art that the position of the tailstock in the height direction cannot be adjusted, and the coaxiality of the headstock center and the tailstock center cannot be observed in real time during the adjustment process, resulting in low adjustment efficiency.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A tailstock center alignment adjustment device for a grinding machine is disclosed. The adjustment device is installed on a cam grinding machine, which includes a headstock, a tailstock, and an operating table. Centers are provided on both the headstock and the tailstock. The adjustment device includes an adjustment mechanism and a detection mechanism. The adjustment mechanism includes a mounting base, a height adjustment component, and a horizontal adjustment component. The mounting base is fixedly installed on the operating table, and the tailstock is movably installed on the mounting base. The height adjustment component adjusts the height of the tailstock, and the horizontal adjustment component moves the tailstock along the width direction of the mounting base. The detection mechanism includes a detection component and two connectors. The two connectors are coaxially sleeved on two centers, and the detection component is positioned between the two connectors. The detection component is used to detect the coaxiality of the two connectors in real time.

[0008] By setting up the above structure, when adjusting the coaxiality of the two centers, the height of the tailstock is adjusted by the height adjustment component, and the tailstock is moved along the width direction of the mounting base by the horizontal adjustment component, thereby realizing the adjustment of the centers on the tailstock. The coaxiality of the two connectors is detected in real time by the detection component to observe the accuracy of the adjustment, effectively improving the adjustment efficiency.

[0009] Furthermore, the detection component includes a connector, a first level, and a second level. The two ends of the connector are respectively ball-jointed with the two connecting heads. The first level is fixedly installed on the top surface of the connector along its length. A mounting plate is provided on the connecting head away from the tailstock end. The mounting plate is located on the side of the connector. A movable plate is rotatably provided on the side of the mounting plate near the connector. The second level is fixedly installed on the movable plate along its length. A first guide plate is fixedly provided on the side of the connector near the movable plate. The first guide plate abuts against the bottom of the movable plate. When the first guide plate moves relative to the movable plate, the first guide plate drives the movable plate to deflect.

[0010] By setting up the above structure, the first level is observed to determine whether the heights of the two centers are consistent. After adjusting the height adjustment component to make the heights of the two centers consistent, the second level is observed to determine whether the two centers are on the same plane in the width direction of the mounting base. The tailstock is moved along the width direction of the mounting base by the level adjustment component until the second level is horizontal, thus achieving the centering adjustment of the two centers. This method is highly accurate, easy to use, and low in cost.

[0011] Furthermore, the horizontal adjustment component includes a first support block and a first driving member, and the height adjustment component includes a second support block, a second driving member, and a guide structure. The first and second support blocks are slidably mounted on the mounting base along the width direction of the mounting base. One end of the bottom of the tailstock is rotatably connected to the first support block. The guide structure is fixedly mounted on the bottom of the tailstock. The second support block abuts against the guide structure. The first and second driving members are respectively used to drive the first and second support blocks to move along the width direction of the mounting base. When the first and second support blocks move synchronously, the tailstock moves along the width direction of the mounting base. When the second support block moves relative to the guide structure, the tailstock deflects about the rotation axis of the first support block.

[0012] By setting the above structure, when the height of the tailstock needs to be adjusted, the position of the second support block can be changed first by the second driving component. The tailstock will deflect around the rotation axis of the first support block. While adjusting the height of the tailstock tip, the tip can be moved a certain distance along the width direction of the mounting base. Then, the positions of the first and second support blocks can be changed synchronously by the first and second driving components, so that the tailstock can be moved along the width direction of the mounting base for fine adjustment until the detection component detects that the two tips are on the same straight line.

[0013] Furthermore, a first mounting groove is provided at one end of the bottom of the tailstock body, the first support block is supported in the first mounting groove, a first through hole is provided on the first support block, and a second through hole is provided at both ends of the first mounting groove. The first through hole and the second through hole are connected, and the same rotating shaft is inserted into the first through hole and the second through hole.

[0014] By setting up the above structure, the stability of the first support block supporting the tailstock body is effectively improved.

[0015] Furthermore, the guiding structure includes a guide groove, the second support block abuts against the inner wall of the guide groove, and the guide groove is inclined from the end away from the first support block to the end closer to the support block from top to bottom.

[0016] By setting up the above structure, the stability of the second support block supporting the tailstock body is effectively improved.

[0017] Furthermore, a second guide plate is fixedly provided on both sides of the guide groove, and a first waist-shaped groove is provided on the second guide plate. The inclination angle of the first waist-shaped groove is the same as the inclination angle of the guide groove. Limiting posts are fixedly provided at both ends of the second support block, and the limiting posts are slidably inserted into the first waist-shaped groove.

[0018] By setting the above structure, the tailstock body is limited to prevent it from moving on its own when the second support block has not moved.

[0019] Furthermore, the first driving component includes a first screw, and the second driving component includes a second screw. Both the first screw and the second screw are arranged along the width direction of the mounting base. The two ends of the first screw are rotatably connected to the mounting base, and the first support block is threadedly connected to the first screw. One end of the second screw is rotatably connected to the first support block, and the other end is slidably connected to the mounting base. The second support block is threadedly connected to the second screw.

[0020] By setting up the above structure, the movement of the first and second support blocks can be controlled by rotating the first and second screws, effectively reducing costs. Furthermore, by rotatably connecting the second screw to the first support block, rotating the first screw allows the second support block to move synchronously via the first and second support blocks. This eliminates the need to separately control the rotation of the first and second screws to move the tailstock body along the width of the mounting base, simplifying operation.

[0021] Furthermore, a third through hole is provided on the second screw along the length direction of the second screw, and the second screw is slidably sleeved on the first screw through the third through hole. A first adjustment knob is fixedly provided at the end of the first screw away from the first support block, and a second adjustment knob is fixedly provided at the end of the second screw away from the first support block.

[0022] By setting the above structure, the first screw and the second screw are coaxially arranged, and the first adjustment knob and the second adjustment knob are located at the same end, which effectively improves the convenience of operation.

[0023] Furthermore, the mounting base is provided with a second mounting groove, and both the first support block and the second support block are located in the second mounting groove. Limiting ribs are provided in the second mounting groove along the width direction of the mounting base. Limiting grooves are provided on both the first support block and the second support block. The first support block and the second support block are slidably locked onto the limiting ribs through the limiting grooves.

[0024] By setting the above structure, both the first support block and the second support block can be slidably mounted on the mounting base along the width direction of the mounting base.

[0025] Furthermore, a first locking plate is fixedly provided at both ends of the first support block, a second locking plate is fixedly provided at both ends of the second support block, and a third locking plate is fixedly provided at both ends of the mounting base. The first locking plate and the second locking plate are detachably connected to the third locking plate.

[0026] By setting the above structure, the third locking plate helps to lock the positions of the first support block and the second support block, effectively reducing the pressure on the first and second driving components and improving their service life.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention, by setting up a height adjustment component, a horizontal adjustment component, and a detection component, adjusts the height of the tailstock by adjusting the coaxiality of the two centers, moves the tailstock along the width direction of the mounting base by the horizontal adjustment component, thereby adjusting the centers on the tailstock, and detects the coaxiality of the two connectors in real time by the detection component to observe the accuracy of the adjustment, thus effectively improving the adjustment efficiency.

[0029] 2. This invention, by setting up a connector, a first level, and a second level, first determines whether the heights of the two centers are consistent by observing the level of the first level. After adjusting the height of the two centers to be consistent by adjusting the height adjustment component, the second level determines whether the two centers are on the same plane in the width direction of the mounting base by observing the level of the second level. The tailstock is moved along the width direction of the mounting base by the level adjustment component until the second level is level, thus achieving the centering adjustment of the two centers. It is highly accurate, easy to use, and low in cost.

[0030] 3. This invention, by setting up a first support block, a first driving member, a second support block, and a second driving member, allows for adjustments to the tailstock height. First, the second driving member changes the position of the second support block, causing the tailstock to deflect around the rotation axis of the first support block. This adjusts the height of the tailstock's tip while simultaneously moving the tip a certain distance along the width of the mounting base. If the detection component detects that the two tips are aligned, there is no need to further adjust the second driving member to move the tailstock along the width of the mounting base. If the two tips are still not aligned, the positions of the first and second support blocks can be simultaneously changed using the first and second driving members to move the tailstock along the width of the mounting base for fine-tuning, further improving adjustment efficiency.

[0031] 4. By setting a first screw and a second screw, and rotatably connecting the second screw to the first support block, when the first screw is rotated, the second support block can be moved synchronously through the first support block and the second screw. The tailstock body can move along the width direction of the mounting base without separately controlling the rotation of the first screw and the second screw. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figures 1-8As shown, this invention discloses a grinding machine tailstock center alignment adjustment device. The adjustment device is installed on a cam grinding machine, which includes a headstock, a tailstock 1, and an operating table. Both the headstock and tailstock 1 are equipped with centers. The adjustment device includes an adjustment mechanism and a detection mechanism. The adjustment mechanism includes a mounting base 2, a height adjustment component 3, and a horizontal adjustment component 4. The mounting base 2 is fixedly installed on the operating table. In this embodiment, the mounting base 2 is locked to the operating table by a clamp. The tailstock 1 is movably installed on the mounting base 2. The height adjustment component 3 is used to adjust the height of the tailstock 1, and the horizontal adjustment component 4 is used to move the tailstock 1 along the width direction of the mounting base 2. The detection mechanism includes a detection component 51 and two connectors 52. The two connectors 52 are coaxially sleeved on two centers, and the detection component 51 is disposed between the two connectors 52. The detection component 51 is used to detect the coaxiality of the two connectors 52 in real time.

[0049] When adjusting the coaxiality of the two centers, the height of the tailstock 1 is adjusted by the height adjustment component 3, and the tailstock 1 is moved along the width direction of the mounting base 2 by the horizontal adjustment component 4 to adjust the centers on the tailstock 1. The coaxiality of the two connectors 52 is detected in real time by the detection component 51 to observe the accuracy of the adjustment and effectively improve the adjustment efficiency.

[0050] In this embodiment, the detection component 51 includes a connector 511, a first level 512, and a second level 513. The two ends of the connector 511 are respectively ball-jointed with two connectors 52. The first level 512 is fixedly installed on the top surface of the connector 511 along the length direction of the connector 511. A mounting plate 521 is provided on the connector 52 away from the end of the tailstock 1. The mounting plate 521 is located on the side of the connector 511. A movable plate 522 is rotatably provided on the side of the mounting plate 521 near the connector 511. The second level 513 is fixedly installed on the movable plate 522 along the length direction of the movable plate 522. A first guide plate 514 is fixedly provided on the side of the connector 511 near the movable plate 522. The first guide plate 514 abuts against the bottom of the movable plate 522. When the first guide plate 514 moves relative to the movable plate 522, the first guide plate 514 drives the movable plate 522 to deflect. In other embodiments, the detection component 51 can also be configured as a laser generator and a scale plate, with the laser generator and scale plate respectively mounted on two connectors 52. The coaxiality of the two tips is determined by observing the position of the laser beam landing on the scale plate. In this embodiment, by setting a first level 512 and a second level 513, the horizontal condition of the first level 512 is first observed to determine whether the heights of the two tips are consistent. After adjusting the height of the two tips to be consistent by adjusting the height adjustment component 3, the horizontal condition of the second level 513 is observed to determine whether the two tips are on the same plane in the width direction of the mounting base 2. The tailstock 1 is moved along the width direction of the mounting base 2 by the horizontal adjustment component 4 until the second level 513 is horizontal, thus achieving the centering adjustment of the two tips. This method is highly accurate, easy to use, and low in cost.

[0051] In this embodiment, a telescopic rod 53 is threaded onto the connector 511. The telescopic rod 53 is arranged along the length of the connector 511. One connector 52 is ball-jointed at the free end of the connector 511, and the other connector 52 is ball-jointed at the free end of the telescopic rod 53. By rotating the telescopic rod 53, the distance between the two connectors 52 can be changed so that the detection component 51 can adapt to the distance between the two tips.

[0052] In this embodiment, an elastic telescopic component 54 is provided on the connector 52 near the tailstock 1. The elastic telescopic component 54 is already fully disclosed in the prior art, so it will not be described in detail here. On the one hand, the position of the connector 52 can be elastically adjusted, making it easy to fit the connector 52 onto the tip. On the other hand, the pressure of the spring in the elastic telescopic component 54 can maintain the stability of the connector 52 fitted onto the tip.

[0053] In this embodiment, the horizontal adjustment component 4 includes a first support block 41 and a first driving member 42, and the height adjustment component 3 includes a second support block 31, a second driving member 32, and a guide structure 33. The first support block 41 and the second support block 31 are slidably mounted on the mounting base 2 along the width direction of the mounting base 2. One end of the bottom of the tailstock 1 is rotatably connected to the first support block 41. The guide structure 33 is fixedly mounted on the bottom of the tailstock 1, and the second support block 31 abuts against the guide structure 33. The first driving member 42 and the second driving member 32 are respectively used to drive the first support block 41 and the second support block 31 to move along the width direction of the mounting base 2. When the first support block 41 and the second support block 31 move synchronously, the tailstock 1 moves along the width direction of the mounting base 2. When the second support block 31 moves relative to the guide structure 33, the tailstock 1 deflects about the rotation axis of the first support block 41. In other embodiments, the horizontal adjustment component 4 can also be configured as a flat-pushing structure, and the height adjustment component 3 as a lifting structure. In this embodiment, by setting a first support block 41, a first driving member 42, a second support block 31, and a second driving member 32, when the height of the tailstock 1 needs to be adjusted, the position of the second support block 31 can be changed first by the second driving member 32. The tailstock 1 will deflect around the rotation axis of the first support block 41, and while adjusting the height of the tip of the tailstock 1, the tip can be moved a certain distance along the width direction of the mounting base 2. If the detection component 51 detects that the two tips are in a straight line, it is not necessary to adjust the second driving member 32 to move the tailstock 1 along the width direction of the mounting base 2. If the two tips are still not in a straight line, the positions of the first support block 41 and the second support block 31 can be changed simultaneously by the first driving member 42 and the second driving member 32 to move the tailstock 1 along the width direction of the mounting base 2 for fine adjustment, further improving the adjustment efficiency.

[0054] In this embodiment, a first mounting groove 11 is provided at one end of the bottom of the tailstock 1 body, and a first support block 41 is supported in the first mounting groove 11. A first through hole is provided on the first support block 41, and a second through hole 111 is provided at both ends of the first mounting groove 11. The first through hole and the second through hole 111 communicate with each other, and the same rotating shaft 43 is inserted into the first through hole and the second through hole 111. In some other embodiments, a connecting seat can also be provided at the bottom of the tailstock 1 and rotatably connected to the first support block 41. For example, connecting seats can be provided at both ends of the tailstock 1, and the first support block 41 can be rotatably connected between the two support seats. By providing the first mounting groove 11 and the rotating shaft 43, this embodiment can effectively improve the stability of the first support block 41 supporting the tailstock 1.

[0055] In this embodiment, the guide structure 33 includes a guide groove 331. The second support block 31 abuts against the inner wall of the guide groove 331. The guide groove 331 is inclined from top to bottom from the end away from the first support block 41 to the end closer to the support block. When the second support block 31 moves towards the first support block 41 along the width direction of the mounting base 2, the top of the second support block 31 presses against the inner top surface of the guide groove 331, causing the tail seat 1 to deflect away from the mounting base 2 about the rotation axis 43. When the second support block 31 moves away from the first support block 41 along the width direction of the mounting base 2, the tail seat 1, under its own weight, deflects towards the mounting base 2 about the rotation axis 43, keeping the inner top surface of the guide groove 331 in contact with the top of the second support block 31. In some other embodiments, the guide structure 33 can also be configured as a guide block fixedly connected to the bottom of the tail seat 1. In this embodiment, by setting a guide groove 331, the second support block 31 is located in the guide groove 331, which can effectively improve the stability of the second support block 31 supporting the tailstock 1 body.

[0056] In this embodiment, a second guide plate 332 is fixedly provided on both sides of the guide groove 331. A first waist-shaped groove 333 is provided on the second guide plate 332. The inclination angle of the first waist-shaped groove 333 is the same as the inclination angle of the guide groove 331. Limiting posts 311 are fixedly provided at both ends of the second support block 31. The limiting posts 311 are slidably inserted into the first waist-shaped groove 333. This limits the tailstock 1 body and prevents the tailstock 1 body from moving on its own when the second support block 31 has not moved.

[0057] In this embodiment, the first driving member 42 includes a first screw 421, and the second driving member 32 includes a second screw 321. Both the first screw 421 and the second screw 321 are arranged along the width direction of the mounting base 2. The two ends of the first screw 421 are rotatably connected to the mounting base 2, and the first support block 41 is threadedly connected to the first screw 421. One end of the second screw 321 is rotatably connected to the first support block 41, and the other end is slidably connected to the mounting base 2. The second support block 31 is threadedly connected to the second screw 321. In some other embodiments, driving cylinders can also be separately provided to push the first support block 41 and the second support block 31 to move. This embodiment, by providing the first screw 421 and the second screw 321, allows control of the movement of the first support block 41 and the second support block 31 by rotating the first screw 421 and the second screw 321, effectively reducing costs. Furthermore, the second screw 321 is rotatably connected to the first support block 41. When the first screw 421 is rotated, the second support block 31 can be moved synchronously through the first support block 41 and the second screw 321. The tailstock 1 body can move along the width direction of the mounting base 2 without separately controlling the rotation of the first screw 421 and the second screw 321, making the operation simple.

[0058] In this embodiment, a third through hole is provided on the second screw 321 along its length. The second screw 321 is slidably sleeved on the first screw 421 through the third through hole. A first adjusting knob 422 is fixedly provided at the end of the first screw 421 away from the first support block 41, and a second adjusting knob 323 is fixedly provided at the end of the second screw 321 away from the first support block 41. In some other embodiments, the first screw 421 and the second screw 321 do not need to be coaxial; they only need to be parallel. This embodiment effectively improves the convenience of operation by coaxially setting the first screw 421 and the second screw 321, and having the first adjusting knob 422 and the second adjusting knob 323 located at the same end.

[0059] In this embodiment, the mounting base 2 has a second mounting groove 21. The first support block 41 and the second support block 31 are both located within the second mounting groove 21. Limiting ribs 22 are provided within the second mounting groove 21 along the width direction of the mounting base 2. Limiting grooves are provided on both the first support block 41 and the second support block 31. Both the first support block 41 and the second support block 31 are slidably engaged with the limiting ribs 22 through the limiting grooves. This allows the first support block 41 and the second support block 31 to be slidably mounted on the mounting base 2 along the width direction of the mounting base 2.

[0060] In this embodiment, a first locking plate 61 is fixedly provided at both ends of the first support block 41, a second locking plate 62 is fixedly provided at both ends of the second support block 31, and a third locking plate 23 is fixedly provided at both ends of the mounting base 2. The first locking plate 61 and the second locking plate 62 are detachably connected to the third locking plate 23. By using the third locking plate 23 to assist in locking the positions of the first support block 41 and the second support block 31, the pressure on the first driving member 42 and the second driving member 32 is effectively reduced, thereby improving the service life of the first driving member 42 and the second driving member 32.

[0061] In this embodiment, the first locking plate 61, the second locking plate 62, and the third locking plate 23 are distributed sequentially from top to bottom along the height direction of the mounting base 2. Both the first locking plate 61 and the second locking plate 62 have a second waist-shaped groove 63. The same fixing bolt 64 passes through the second waist-shaped groove 63 of the first locking plate 61 and the second locking plate 62. The fixing bolt 64 is threadedly connected to the third locking plate 23, and is used to lock the first locking plate 61, the second locking plate 62, and the third locking plate 23. In some other embodiments, the first locking plate 61 and the third locking plate 23 can also be locked separately by the fixing bolts 64, and the second locking plate 62 and the third locking plate 23 can also be locked separately. In this embodiment, by providing the second waist-shaped groove 63 and locking the two fixing bolts 64 at both ends of the mounting base 2 to the third locking plate 23, the first support block 41 and the second support block 31 can be locked simultaneously, facilitating operation.

[0062] The working principle of this invention is as follows:

[0063] First, coaxially mount the two connectors 52 onto the two tops of the headstock and tailstock 1 respectively. Loosen the two fixing bolts 64 at both ends of the mounting base 2 to disengage the first locking plate 61 and the second locking plate 62 from the third locking plate 23, so that the first support block 41 and the second support block 31 can move along the width direction of the mounting base 2.

[0064] Then, observe the horizontal state of the first level 512, and by rotating the second adjustment knob 323, the second support block 31 is moved along the width direction of the mounting base 2 by the second screw 321, so that the tail seat 1 deflects around the rotating shaft 43 until the first level 512 is in a horizontal state.

[0065] Then, observe the horizontal state of the second level 513, rotate the first adjustment knob 422, and drive the first support block 41 to move along the width direction of the mounting base 2 via the first screw 421. While the first support block 41 moves, on the one hand, the tail seat 1 body moves along the width direction of the mounting base 2 via the rotating shaft 43, and on the other hand, the second support block 31 moves along the width direction of the mounting base 2 via the second screw 321. That is, the first support block 41 and the second support block 31 move synchronously, so that the tail seat 1 moves along the width direction of the mounting base 2 for fine adjustment until the second level 513 is in a horizontal state.

[0066] Finally, tighten the two fixing bolts 64 at both ends of the mounting base 2 to lock the first locking plate 61 and the second locking plate 62 with the third locking plate 23, preventing the first support block 41 and the second support block 31 from moving along the width direction of the mounting base 2.
