Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a V-type adjustable support for an internal grinding machine. Background Technology

[0002] Internal grinding machines are mainly used for grinding the inner surfaces and end faces of cylindrical, conical, or other shaped internal holes formed by generatrices. They have advantages such as eliminating the need for secondary tool setting, high safety, and high speed. When machining shaft parts, especially long and heavy cylindrical parts, a center rest is required to support the cylindrical parts.

[0003] Chinese Patent CN106112713A discloses an integrated measurement, monitoring, and machining device and control system for CNC deep hole internal grinding machines. It includes a CNC grinding machine mainframe and an in-situ measurement device for deep hole dimensions and shape. The CNC grinding machine mainframe is equipped with an X-axis feed system and a Z-axis feed system. The Z-axis feed system includes a Z-axis guide rail, a worktable slidably mounted on the Z-axis guide rail, and a Z-axis drive device. The X-axis feed system includes an X-axis guide rail, a spindle head mount slidably mounted on the X-axis guide rail, and an X-axis drive device. A grinding wheel spindle head is mounted on the spindle head mount, and the power output end of the grinding wheel spindle head is connected to a grinding rod. The in-situ measurement device for deep hole dimensions and shape includes a measuring rod, an X-axis linear encoder, and a Z-axis linear encoder. The measuring rod is mounted on the spindle head mount, and a measuring stylus is mounted at the head of the measuring rod. This invention combines precision machining of a machine tool with online measurement and control, replacing some of the functions of a coordinate measuring machine (CMM), improving the efficiency of deep hole measurement and machining, and enhancing the controllability of the machining process.

[0004] Regarding the aforementioned technologies, in existing technologies, operators use two center supports mounted on a grinding machine to assist in lifting cylindrical parts and use a chuck to clamp the workpiece, causing the cylindrical parts to rotate. However, the center supports in existing technologies use a structure with two types of screws for auxiliary support and one screw for top pressure to limit the position of the cylindrical parts. This type of center support has poor support rigidity, and adjusting the axis of the cylindrical parts to coincide with the rotation axis of the grinding machine chuck using this center support is cumbersome and difficult. This is because when adjusting the screws used for auxiliary support, the cylindrical parts will have distance variables in two directions. This can easily increase the installation error of the cylindrical parts, causing circular runout when the cylindrical parts rotate, reducing the stability of the cylindrical parts' rotation, and reducing the grinding accuracy of the internal grinding machine. Summary of the Invention

[0005] To improve the grinding accuracy of internal grinding machines, this application provides a V-type adjustable support for internal grinding machines.

[0006] This application provides a V-type adjustable support for an internal grinding machine, using the following technical solution:

[0007] A V-shaped adjustable bracket for an internal grinding machine includes several mounting seats mounted on the grinding machine. Each mounting seat has a support fixture and a horizontal adjustment assembly for adjusting the position of the support fixture. The support fixture is mounted on the horizontal adjustment assembly. The support fixture includes a first support block, a second support block, a support plate, and a clamping member. The first support block is connected to the mounting seat, and the second support block is slidably fitted onto the mounting seat. The mounting seat has a height adjustment assembly for adjusting the position of the second support block. The first and second support blocks are arranged opposite to each other. Supporting inclined surfaces are provided on the opposite sidewalls of the first and second support blocks, forming a V-groove. A cylindrical part is placed between the two supporting inclined surfaces. The support plate is installed between the first and second support blocks, and the clamping member is disposed on the support plate, serving to abut against the cylindrical part.

[0008] By adopting the above technical solution, when installing cylindrical parts, the operator places the cylindrical parts on two supporting inclined surfaces, and then uses the height adjustment component to adjust the second support block to adjust the height position of the cylindrical parts until the axis of the cylindrical parts is aligned with the axis of the rotating end of the grinding machine. Then, the horizontal adjustment component is used to adjust the position of the cylindrical parts so that the axis of the cylindrical parts coincides with the axis of the rotating end of the grinding machine. Subsequently, a support plate is installed between the first support block and the second support block. Finally, the clamping component is used to fit the cylindrical parts, thus realizing the debugging and installation of the cylindrical parts. The operator utilizes the gravity of the cylindrical part acting on two supporting inclined surfaces, and with the clamping component fitting against the top of the cylindrical part, achieves three-point positioning of the cylindrical part. The height adjustment component is used to adjust the height position of the cylindrical part individually, and the horizontal adjustment component is used to adjust the horizontal position of the cylindrical part individually. Each adjustment only targets the distance variable in one direction of the cylindrical part, making the adjustment simple, reducing the installation error of the cylindrical part, and reducing the possibility of circular runout when the cylindrical part rotates. At the same time, the support fixture structure is reliable and has high support rigidity, making the cylindrical part more stable when rotating and improving the grinding accuracy of the internal grinding machine.

[0009] Optionally, both the first support block and the second support block are equipped with support columns, and a connecting screw is connected to the support column. The maximum diameter of the connecting screw is smaller than the diameter of the support column. A connecting nut is threaded onto the connecting screw. The support plate is located between the connecting nut and the support column. The clamping member is a clamping bolt. The clamping member passes through the support plate until it abuts against the cylindrical part. The clamping member is threadedly engaged with the support plate.

[0010] By adopting the above technical solution, when stabilizing cylindrical parts, the workers place the support plate on the support column, then rotate the connecting nut to stabilize the support plate, and then rotate the clamping part to lower it until it fits against the cylindrical part, thus achieving the effect of stabilizing the cylindrical part.

[0011] Optionally, a butterfly spring and a connecting cylinder are sleeved on the connecting screw, with the butterfly spring located below the connecting cylinder, and both the butterfly spring and the connecting cylinder located between the connecting nut and the support plate.

[0012] By employing the above technical solution, the cylindrical parts generate heat during grinding, causing them to expand and deform, which in turn lifts the clamping components and support plate. The workers utilize the elastic deformation of the disc springs to absorb the movement of the support plate caused by the deformation of the cylindrical parts, reducing the possibility of damage to the entire support fixture.

[0013] Optionally, a cemented carbide rod is connected to the inclined support surface, the cemented carbide rod being parallel to the inclination direction of the inclined support surface, and the cemented carbide rod being used to support the cylindrical part.

[0014] By adopting the above technical solution, when the cylindrical part is frustum-shaped, the contact between the supporting inclined surface and the cylindrical part is point contact, and the edge of the supporting inclined surface is prone to scratching the surface of the cylindrical part. When the cylindrical part is cylindrical, the contact between the cylindrical part and the supporting inclined surface is surface contact, which increases the friction between the supporting inclined surface and the cylindrical part. The cemented carbide rod can reduce the contact area between the supporting inclined surface and the cylindrical part, reduce the possibility of surface damage to the cylindrical part, and make the cylindrical part rotate more smoothly.

[0015] Optionally, the height adjustment assembly includes a fixed block, a first adjusting bolt, and a first fixed slide bar. The fixed block is connected to the horizontal adjustment assembly, and the first fixed slide bar is connected to the horizontal adjustment assembly and is parallel to the moving direction of the second support block. The second support block has a sliding groove at the position corresponding to the first fixed slide bar, and the first fixed slide bar slides in cooperation with the sliding groove. The first adjusting bolt is rotatably connected to the fixed block and passes through the second support block. The first adjusting bolt is threadedly engaged with the second support block.

[0016] By adopting the above technical solution, when adjusting the height of cylindrical parts, the operator rotates the first adjusting bolt to move the first support block, and the cylindrical parts move until the axis of the cylindrical parts is aligned with the axis of the rotating end of the grinding machine, thus achieving the effect of adjusting the height of the cylindrical parts.

[0017] Optionally, the leveling assembly includes an adjusting block, a moving block, a second adjusting bolt, and a second fixing slide bar. The fixing block, the first support block, the second support block, and the first fixing slide bar are all disposed on the moving block. The adjusting block is connected to the mounting base. The second fixing slide bar is connected to the mounting base and is parallel to the first fixing slide bar. The moving block has a moving groove at the position corresponding to the second fixing slide bar. The second fixing slide bar is slidably engaged with the moving groove. The second adjusting bolt is rotatably connected to the adjusting block. The second adjusting bolt passes through the moving block and is threadedly engaged with the moving block.

[0018] By adopting the above technical solution, when adjusting the horizontal position of cylindrical parts, the operator rotates the second adjusting bolt to move the moving block, which in turn moves the entire support fixture horizontally until the axis of the cylindrical parts is aligned with the axis of the rotating end of the grinding machine, thus achieving the effect of adjusting the horizontal position of the cylindrical parts.

[0019] Optionally, the mounting base is provided with a mounting assembly, which includes a clamping seat, a stabilizing block, a clamping block, and a locking bolt. The clamping seat is connected to the mounting base, the stabilizing block is connected to one end of the clamping seat, and the other end of the clamping seat is provided with a supporting step. The clamping block is located at the other end of the clamping seat and abuts against the supporting step. The sidewalls of the clamping block and the stabilizing block are provided with clamping inclined surfaces. The grinding machine is provided with a mounting guide rail, which is designed in a dovetail shape and is located between the two clamping inclined surfaces. The locking bolt passes through the clamping block and the clamping seat and is threadedly engaged with the clamping seat.

[0020] By adopting the above technical solution, when stabilizing the mounting base, the operator places the clamping base on the mounting guide rail, presses the clamping inclined surface of the stabilizing block against one side wall of the mounting guide rail, and rotates the locking bolt to move the clamping block. Simultaneously, the clamping inclined surface of the clamping block presses against the other side wall of the mounting guide rail, and the clamping block presses against the supporting step, thus achieving the effect of stabilizing the mounting base on the grinding machine mounting guide rail. The operator uses the stabilizing block to limit the position of the mounting base on the grinding machine, ensuring that all mounting bases are flush.

[0021] Optionally, the mounting base is provided with a rotating assembly, which includes an inspection bar, an end cap, a pull rope, and a rotating block. The end cap is used to connect to the end of the cylindrical part. The inspection bar is installed on the rotating end of the grinding machine and abuts against the end cap. The rotating block is rotatably connected to both the rotating end of the grinding machine and the end cap. The pull rope is connected between the two rotating blocks.

[0022] By adopting the above technical solution, when the cylindrical part rotates, the operator installs the inspection bar on the rotating end of the grinding machine, then connects the end cap to the end of the cylindrical part, tightens the pull rope between the two rotating blocks, and starts the grinding machine, causing the rotating blocks installed on the rotating end of the grinding machine to rotate. Through the pull rope, the end cap rotates, achieving the effect of rotating the cylindrical part. When adjusting the position of the cylindrical part, the operator can also use the rotating assembly to slowly rotate the cylindrical part, quickly and initially adjust the position of the corresponding second support block based on the location of the cylindrical part with the largest circular runout, improving the installation efficiency of the cylindrical part. The rotating assembly, in conjunction with the positional limitation of the support fixture, drives the cylindrical part to rotate slowly, achieving the grinding of the cylindrical part.

[0023] Optionally, a retaining bead is rotatably connected to one end of the inspection bar near the support fixture, the retaining bead being used to abut against the end cap.

[0024] By adopting the above technical solution, the difference in position between the two rotating blocks causes the cylindrical parts to move under traction during rotation. The friction between the inspection bar and the end cap is surface contact, affecting the rotation of the cylindrical parts. Workers use a retaining bead to press against the end cap, making the contact between the end cap and the inspection bar point-to-point, allowing the cylindrical parts to rotate more effectively.

[0025] Optionally, the mounting base is provided with a preliminary positioning component, which includes a synchronizing column, a fixed plate, a movable plate, a lifting block, and a reference block. The first support block and the second support block have the same structure. The synchronizing column is inserted between the first support block and the second support block. The fixed plate is connected to the second support block. The lifting block is vertically slidably fitted on the fixed plate. The movable plate is horizontally slidably fitted on the fixed plate. The movable plate is used to abut against the cylindrical part. The reference block is connected to the end cover and is used to abut against the clamping bead. When the axis of the cylindrical part coincides with the axis of the rotating end of the grinding machine, the movable plate abuts against the lifting block and the cylindrical part.

[0026] By adopting the above technical solution, when initially positioning the height of cylindrical parts, the operator first inserts the synchronizing column between the two first support blocks to make the two first support blocks level. Then, the cylindrical part is placed on the support slope. After the rotating component is installed, the cylindrical part is rotated, and the relative position of the reference block and the clamping ball is observed. The position of the two second support blocks is initially adjusted using the height adjustment component to make the relative position between the clamping ball and the reference block as close as possible. At the same time, the moving plate moves against the cylindrical part. As the second support block moves, the moving plate moves against the lifting block, preventing the lifting block from moving up or down. At this time, the height of the cylindrical part is as close as possible to the axis height of the rotating end of the grinding machine. The position of the other second support block is limited by the above method, thereby further reducing the installation error of the cylindrical part and achieving the effect of initially positioning the height of the cylindrical part. The workers first use the relative position of the clamping ball and the reference block to initially adjust the position of the two second support blocks. Then, they use the friction between the lifting block and the moving plate to further adjust the position of the two second support blocks. At this point, the installation error of the cylindrical parts is minimized. Then, a dial indicator is used to check and fine-tune the second support blocks, thereby shortening the debugging time of the second support blocks and improving the installation efficiency of the cylindrical parts.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When installing cylindrical parts, the operator places the part on two inclined support surfaces. Then, using the height adjustment component, the second support block is adjusted to control the height of the cylindrical part until its axis aligns with the axis of the grinding machine's rotating end. Next, the horizontal adjustment component is used to adjust the part's position so that its axis coincides with the axis of the grinding machine's rotating end. A support plate is then installed between the first and second support blocks. Finally, a clamping component is used to secure the cylindrical part, completing the installation. The operator utilizes the weight of the cylindrical part on the two inclined support surfaces, along with the clamping component securing the top of the part, to achieve three-point positioning. The height adjustment component adjusts the height of the cylindrical part individually, and the horizontal adjustment component adjusts its horizontal position individually. Each adjustment targets only one direction of distance, reducing adjustment difficulty, minimizing installation errors, and reducing the possibility of circular runout during rotation. Simultaneously, the robust support structure and high rigidity ensure greater stability during rotation, improving the grinding accuracy of the internal grinding machine.

[0029] 2. When initially positioning the height of cylindrical parts, the operator first inserts the synchronizing column between the two first support blocks, aligning the two first support blocks. Then, the cylindrical part is placed on the support slope. After installing the rotating assembly, the cylindrical part is rotated, and the relative position of the reference block and the clamping ball is observed. The position of the two second support blocks is initially adjusted using the height adjustment assembly, making the relative position between the clamping ball and the reference block as close as possible. At the same time, the moving plate moves against the cylindrical part. As the second support blocks move, the moving plate moves against the lifting block, preventing the lifting block from moving up or down. At this point, the height of the cylindrical part is as close as possible to the axis height of the rotating end of the grinding machine. The position of the other second support block is limited by the above method, thereby further reducing the installation error of the cylindrical part and achieving the effect of initially positioning the height of the cylindrical part. The workers first use the relative position of the clamping ball and the reference block to initially adjust the position of the two second support blocks. Then, they use the friction between the lifting block and the moving plate to further adjust the position of the two second support blocks. At this point, the installation error of the cylindrical parts is minimized. Then, a dial indicator is used to check and fine-tune the second support blocks, thereby shortening the debugging time of the second support blocks and improving the installation efficiency of the cylindrical parts.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] Embodiment 1 of this application discloses a V-shaped adjustable support for an internal grinding machine. (See also...) Figure 1 The V-shaped adjustable bracket for the internal cylindrical grinding machine includes several mounting seats 1 set on the grinding machine 01. In this embodiment, two are used as an example, and the mounting seat 1 is a rectangular block.

[0038] Reference Figure 1 and Figure 2 Mounting base 1 is equipped with mounting component 2, which includes clamping seat 21, stabilizing block 22, clamping block 23, and locking bolt 24. A mounting guide rail 012 is fixedly connected to the grinding machine 01. The mounting guide rail 012 is dovetail-shaped, and mounting base 1 is perpendicular to the mounting guide rail 012. Clamping seat 21 is bolted to the bottom wall of mounting base 1 and is mounted on the mounting guide rail 012.

[0039] Reference Figure 1 and Figure 2 The stabilizing block 22 is bolted to one end of the clamping seat 21. A supporting step 211 is provided at the other end of the clamping seat 21, and the clamping block 23 is located at the other end of the clamping seat 21, abutting against the supporting step 211. A locking bolt 24 passes through the clamping block 23 and the clamping seat 21, and is threaded into the clamping seat 21. Clamping ramps are provided on the opposite side walls of the clamping block 23 and the stabilizing block 22, and these ramps fit against the side wall of the mounting guide rail 012.

[0040] When securing the mounting base 1, the worker places the clamping seat 21 on the mounting guide rail 012, and then rotates the locking bolt 24 to make the clamping inclined surface on the clamping block 23 fit against the side wall of the mounting guide rail 012, driving the entire mounting base 1 to move until both clamping inclined surfaces are pressed against the side wall of the mounting guide rail 012, thus realizing the installation of the mounting base 1.

[0041] Reference Figure 2 A horizontal adjustment assembly 3 is provided on the mounting base 1. The horizontal adjustment assembly 3 includes an adjusting block 31, a moving block 32, a second adjusting bolt 33, and a second fixing slide bar 34. The adjusting block 31 is bolted to one end of the mounting base 1 near the clamping block 23. Several second fixing slide bars 34 are embedded in the mounting base 1. In this embodiment, two slide bars are used as an example. The second fixing slide bars 34 are parallel to the length direction of the mounting base 1. A moving groove is opened on the bottom wall of the moving block 32, and the second fixing slide bar 34 slides in the moving groove. The second adjusting bolt 33 passes through the adjusting block 31 and the moving block 32. The second adjusting bolt 33 is provided with a second limiting groove. The second limiting bolt is threadedly engaged with the adjusting block 31. The second limiting bolt is embedded in the second limiting groove. The second adjusting bolt 33 is threadedly engaged with the moving block 32.

[0042] When adjusting the position of the movable block 32, the operator rotates the second adjusting bolt 33 to move the movable block 32 along the length of the mounting base 1, thereby achieving the effect of adjusting the horizontal position of the movable block 32.

[0043] Reference Figure 2 and Figure 3 The movable block 32 is equipped with a support fixture 4, which includes a first support block 41, a second support block 42, a support plate 43, and a clamping element 44. Both the first support block 41 and the second support block 42 are bolted to the movable block 32. The first support block 41 and the second support block 42 are positioned opposite each other, and support inclined surfaces 5 are formed on their opposite sidewalls, creating a V-groove. A carbide rod 51 is embedded in the support inclined surface 5, serving as an auxiliary support for cylindrical parts.

[0044] Reference Figure 2 and Figure 3Each of the first support block 41 and the second support block 42 is threaded with a support post 45. A connecting screw 46 is fixedly connected to the top of each support post 45, and the diameter of the support post 45 is larger than the maximum diameter of the connecting screw 46. A clearance groove is formed on the support plate 43 corresponding to the positions of the two connecting screws 46. The connecting screws 46 pass through the clearance groove, and the support plate 43 abuts against the top of the support post 45. A butterfly spring 47 and a connecting cylinder 48 are sequentially fitted onto the connecting screw 46. A connecting nut 49 is threaded onto the connecting screw 46, and the connecting nut 49 abuts against the top of the connecting cylinder 48. A fastening nut is also threaded onto the connecting screw 46, and the fastening nut abuts against the connecting nut 49 to prevent loosening of the connecting nut 49. The cooperation of the butterfly spring 47 and the connecting cylinder 48 is used to absorb the movement distance of the support plate 43 caused by the thermal expansion of the cylindrical parts.

[0045] Reference Figure 3 The clamping element 44 is a clamping bolt that passes through the support plate 43 and is threadedly engaged with it. The clamping element 44 is made of a wear-resistant material, such as tin bronze. A lock nut is also threaded onto the clamping element 44, which presses against the top wall of the support plate 43 to reduce the possibility of the clamping element 44 loosening.

[0046] Reference Figure 2 The movable block 32 is equipped with a height adjustment component 6, which includes a fixed block 61, a first adjusting bolt 62, and a first fixed slide bar 63. The fixed block 61 is bolted to the end of the movable block 32 near the adjusting block 31. The first fixed slide bar 63 is embedded in the movable block 32 at positions corresponding to the first support block 41 and the second support block 42, and is parallel to the moving direction of the movable block 32. Sliding grooves are formed on the bottom walls of both the first support block 41 and the second support block 42, and the first fixed slide bar 63 slides within these grooves. The first adjusting bolt 62 passes through the fixed block 61 and the second support block 42, and has a first limiting groove. A first limiting bolt is threaded onto the fixed block 61, and is fitted into the first limiting groove. The first adjusting bolt 62 is threaded into the second support block 42.

[0047] When clamping cylindrical parts, the operator places the cylindrical parts on two supporting inclined surfaces 5, rotates the first adjusting bolt 62 to move the second supporting block 42, and moves the cylindrical parts until the height of the axis of the cylindrical parts is aligned with the height of the axis of the rotating end 011 of the grinding machine 01. A support plate 43 is fitted onto the connecting screw 46, and then a butterfly spring 47 and a connecting cylinder 48 are sequentially fitted onto the connecting screw 46. Then, the connecting nut 49 and the fastening nut are rotated sequentially to install the support plate 43. Finally, the clamping member 44 is rotated so that the lower end of the clamping member 44 fits against the cylindrical parts, thus achieving the effect of clamping the cylindrical parts.

[0048] Reference Figure 1 and Figure 4 The grinding machine 01 is equipped with a rotating assembly 7, which includes an inspection bar 71, an end cap 72, a pull rope 73, and rotating blocks 74. The inspection bar 71 is mounted on the rotating end 011 of the grinding machine 01, and a clamping bead 711 is embedded at the end of the inspection bar 71 near the support fixture 4. The end cap 72 is bolted to one end of the cylindrical part. A rotating bolt passes through the rotating block 74, and a clamping nut is threaded onto the rotating bolt. One rotating block 74 is connected to both the end cap 72 and the rotating end 011 of the grinding machine 01 through the engagement of the rotating bolt and the clamping nut. Several mounting bolts are threaded onto the rotating block 74. The pull rope 73 is connected between two rotating blocks 74 via mounting bolts. The pull rope 73 is a cotton rope, which helps to eliminate stress from pulling the end cap 72. The rotating assembly 7 is used in conjunction with the support fixture 4.

[0049] When the cylindrical parts rotate, the operator starts the grinding machine 01. Through the cooperation of the rotating block 74 and the pull rope 73, the end cover 72 is pulled to rotate, thus achieving the effect of slow rotation of the cylindrical parts.

[0050] The implementation principle of the V-type adjustable bracket for an internal grinding machine in Embodiment 1 of this application is as follows: When adjusting the position of a cylindrical part, the operator places the cylindrical part on two supporting inclined surfaces 5, rotates the first adjusting bolt 62 to move the second supporting block 42, and adjusts the height of the cylindrical part until the height of the cylindrical part's axis is flush with the height of the axis of the rotating end 011 of the grinding machine 01. Then, the operator rotates the second adjusting bolt 33 to move the moving block 32, and adjusts the horizontal position of the cylindrical part until the axis of the cylindrical part coincides with the axis of the rotating end 011 of the grinding machine 01. Then, the operator sleeves the support plate 43 on the connecting screw 46, and then sequentially sleeves the butterfly spring 47 and the connecting cylinder 48 on the connecting screw 46. Then, the operator rotates the connecting nut 49 and the fastening nut in sequence to install the support plate 43. Then, the operator rotates the clamping member 44 so that the lower end of the clamping member 44 fits against the cylindrical part, thus realizing the adjustment and installation of the cylindrical part.

[0051] The operator utilizes the gravity of the cylindrical part acting on two supporting inclined surfaces 5, and with the clamping component 44 fitting against the top of the cylindrical part, achieves three-point positioning of the cylindrical part. The height adjustment component 6 is used to adjust the height position of the cylindrical part individually, and the horizontal adjustment component 3 is used to adjust the horizontal position of the cylindrical part individually. Each adjustment only targets the distance variable in one direction of the cylindrical part, making the adjustment easy, reducing the installation error of the cylindrical part, and reducing the possibility of circular runout when the cylindrical part rotates. At the same time, the support fixture 4 has a reliable structure and strong support rigidity, making the cylindrical part more stable when rotating and improving the grinding accuracy of the internal cylindrical grinding machine 01.

[0052] Example 2: The difference between this example and Example 1 is the addition of a technical means to initially determine the height of cylindrical parts.

[0053] Reference Figure 4 and Figure 5 The support fixture 4 is equipped with a preliminary positioning component 8, which includes a synchronizing column 81, a fixed plate 82, a movable plate 83, a lifting block 84, and a reference block 85. The synchronizing column 81 is inserted between two first support blocks 41. The fixed plate 82 is fixedly connected to the support column 45 of the second support block 42. An installation block is bolted to the fixed plate 82. The lifting block 84 is L-shaped and slides vertically on the installation block. The distance between the horizontal ends of the lifting block 84 depends on the diameter of the cylindrical part. The installation block and the lifting block 84 are replaced according to the diameter of the cylindrical part. The movable plate 83 is located on one side of the fixed plate 82. Several sliding rods are fixedly connected to the movable plate 83. In this embodiment, two rods are used as an example. The sliding rods pass through the fixed plate 82 and slide with it. A return spring is sleeved on the sliding rod. The return spring and the lifting block 84 are both located between the fixed plate 82 and the movable plate 83. Reference block 85 is embedded on end cap 72 at the position corresponding to abutment bead 711. Reference block 85 is made of wear-resistant material, such as hard alloy. Reference block 85 is used to abut abutment bead 711.

[0054] When initially determining the height of cylindrical parts, the operator first inserts the synchronizing column 81 between the two first support blocks 41 to synchronize their installation positions. Then, the cylindrical part is placed on the two support ramps 5, the end cap 72 is installed on the part, the inspection bar 71 is installed on the rotating end 011 of the grinding machine 01, and the pull rope 73 is installed between the two rotating blocks 74. The grinding machine 01 is started, and the end cap 72 is slowly rotated by pulling the cotton rope. At this time, the end cap 72 moves under the influence of traction, and the clamping bead 711 contacts the reference block 85. The relative position of the clamping bead 711 and the reference block 85 is observed. The second support block 42 is moved in conjunction with the height adjustment component 6 to bring the clamping bead 711 into contact with the reference block 85. By making the relative position of reference block 85 as close as possible to initially locate the height of the cylindrical part, the second support block 42 is moved further until the moving plate 83 contacts the cylindrical part, and then the moving plate 83 contacts the lifting block 84, making the lifting block 84 unable to move. At this time, the height of the cylindrical part is close to the axial height of the rotating end 011 of the grinding machine 01. The second support block 42 on the other mounting base 1 is adjusted in this way, which further reduces the error between the axis of the cylindrical part and the axis of the rotating end 011 of the grinding machine 01, and achieves the initial positioning of the height of the cylindrical part. Finally, the straightness of the cylindrical part can be accurately checked with tools such as a dial indicator, thereby shortening the debugging time of the cylindrical part and improving the debugging efficiency of the cylindrical part.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
