[0002] Guide bar tools focus on finishing work of various types of high-precision deep holes. The machining accuracy of the tools can reach IT5-IT7 level, but the tool size needs to be adjusted, and the adjustment steps are relatively cumbersome, which requires a certain level of skill from the operator. Therefore, the machining accuracy of the tool is largely affected by the operator's tool adjustment skills. Most of the tool adjustment equipment on the market currently adjusts the position or distance of each structure manually by the operator, but the operator needs to have a skilled control of accuracy, which places high requirements on the operator, and manual operation will inevitably result in some unavoidable errors.

The measuring head and the mounting seat are respectively arranged on both ends of the measuring rod. The measuring rod passes through the guide frame and is fixed thereto. A micrometer can also be installed on the mounting seat.

[0018] The detection head is mounted on the bottom wall of the guide frame and is located below the two sets of measuring bridges.

[0019] In one embodiment, the driving assembly includes a shaft seat, a worm wheel 1, a worm wheel 2, a worm, a swing arm and a synchronous wheel 3, two shaft seats are provided and are both installed on the top surface of the base, a rotating shaft 2 is rotatably provided between the shaft seats on both sides, two swing arms are provided and are symmetrically installed on the rotating shaft 2, and the worm is rotatably provided between the other ends of the swing arms on both sides, and the worm can be respectively meshed with the worm wheel 1 and the worm wheel 2 for transmission;

[0020] A limit plate 1 is arranged near the top end of the screw rod 1, and a limit plate 2 is arranged near the top end of the rotating shaft 1. Both the limit plate 1 and the limit plate 2 are electromagnets that can generate suction when energized, and a connecting shaft that can rotate and contact with them is passed through the middle of the limit plate 1 and the limit plate 2. The bottom end of the connecting shaft is an "I"-shaped structure, and when there is suction on the limit plate 1 and the limit plate 2, the connecting shaft can be connected to the limit plate 1 or the limit plate 2 in contact with it as a whole, and the connecting shaft is also provided with the synchronous wheel 3 that rotates synchronously with it, and a synchronous belt is also installed between the synchronous wheels 3 on both sides, wherein the worm gear 1 is fixed on the top end of one of the connecting shafts, and the worm gear 2 is fixed at the top end of the other connecting shaft, and the worm gear 1 and the worm gear 2 are mirror-symmetrical about the vertical center line of the rotating shaft 2.

[0021] In one embodiment, when there is suction on the limit plate 1 and there is no suction on the limit plate 2, the worm is in a state of meshing with the worm wheel 1, the worm wheel 1 rotates synchronously with the screw 1, and the connecting shaft on the limit plate 2 only drives the worm wheel 2 to rotate synchronously with the rotation of the worm wheel 1 under the action of the synchronous wheel 3 and the synchronous belt. In this state, the adjusting member can perform vertical displacement movement;

[0022] When there is suction on the limit plate 2 and there is no suction on the limit plate 1, the worm is in a state of meshing with the worm wheel 2, the rotating shaft 1 rotates synchronously with the worm wheel 2, and the worm wheel 1 on the other side also rotates synchronously with the rotation of the worm wheel 2, but the screw 1 does not rotate.

[0025] In one embodiment, when the worm gear 2 rotates, the rotating shaft 1 is synchronized therewith and drives the input member to rotate, so that the driving disk and the fixed shaft make circular motion together. During the motion, the driving disk intermittently rotates in contact with the arc groove, and at the same time, the fixed shaft also intermittently slides in contact with the groove in a rotating state.

[0028] S2, then, the position of the worm is switched to mesh with the second worm gear, and the measuring assembly is controlled to start moving and adjusting from top to bottom along the vertical direction. During the movement, the guide bar cutter is first rotated and adjusted by the rotating shaft 1. After the rotation, the measuring assembly is adjusted downward under the action of the screw 2, so that the position of the blade edge can be automatically found by rotating first and then adjusting downward;

[0029] S3. Then, after finding the position of the blade edge, move the guide frame to make the measuring bridge contact with the blade edge, adjust the micrometer to zero, and then the operator manually adjusts the adjustment screw of the blade while observing the changes in the indicator pointer to adjust the blade edge size to the desired size.

The accuracy of the tool adjustment process is improved, and the automation effect of the tool adjustment equipment is also achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0044] like Figure 1 As shown, the present invention provides a technical solution: a tool adjustment device based on a guide bar tool, comprising a base 1, a protective member 2, a fixing member 3, an adjusting member 4 and a measuring component 5. Five support feet that can prevent slipping are installed on the bottom of the base 1 by means of threaded connection. A fixing platform 11 is installed on the base 1 by means of screws. One side of the fixing platform 11 is connected to the protective member 2, and a control panel 21 with a PLC controller is installed on the outer surface of the protective member 2. The fixing member 3 is installed at a fixed position along the vertical direction of the protective member 2. The adjusting member 4 is slidably adjusted along the vertical direction of the protective member 2 and is arranged opposite to the fixing member 3. The guide bar tool to be measured can be clamped between the adjusting member 4 and the fixing member 3 in the vertical direction, and a measuring component 5 is arranged on one side of the guide bar tool. The measuring component 5 also moves and adjusts along the vertical direction of the protective member 2. The measuring component 5 is adjusted based on the guide bar of the guide bar tool, thereby cooperating with the worker to complete the tool adjustment preparation.

[0045] like Figure 2-3 As shown, the protective member 2 includes a base 22, a casing 23, a screw rod 1 24, a rotating shaft 1 25 and a screw rod 26;

[0046] One end of the base 22 is fixed to the base 1 by bolts and is connected and fixed to the circumferential surface of the fixed platform 11. Two symmetrical through holes are opened on the base 22 along its vertical direction, and a cavity arranged along the vertical direction is also opened inside the base 22. The cavity is located in the middle of the through holes on both sides. A screw 24 is rotatably arranged between the inner walls of the cavity. The screw 24 is used to control the height position of the adjusting member 4. A rotating shaft 25 distributed along the vertical direction is also rotatably arranged outside the base 22. The rotating shaft 25 is used to control the rotation adjustment of the guide strip tool to be measured. The sleeve 23 is installed between the side walls of the base 22 by snap-fitting and forms an integral body with it. A top cover is also installed between the base 22 and the top of the sleeve 23 by snap-fitting. Screw 26 is rotatably arranged between the inner top wall of the sleeve 23 and the top surface of the base 1 along the vertical direction. The setting of screw 26 is to control the automatic height adjustment of the measuring component 5.

[0047] The bottom ends of the screw rod 1 24, the rotating shaft 1 25 and the screw rod 2 26 are all provided with electromagnets in rotational contact therewith (the electromagnets at the bottom ends of the rotating shaft 1 25 and the screw rod 2 26 are as shown in FIG. Figure 3 As shown in the figure, the electromagnet at the bottom end of the screw 1 24 is not shown in the figure), the screw 1 24, the shaft 1 25 and the screw 2 26 can all be attracted by the magnetic force generated by the electromagnet after being energized, thereby ensuring that the screw 1 24 cannot move when the worm gear 2 63 is engaged with the worm 64, and the shaft 1 25 and the screw 2 26 cannot move when the worm gear 1 62 is engaged with the worm 64.

[0048] like Figure 2-4 As shown, the fixing member 3 includes a fixing seat 31, a mounting plate 32 and a synchronous wheel 33;

[0049] The bottom end of the fixing seat 31 contacts and is fixed to the top of the fixing platform. One end of the fixing seat 31 is in a "U"-shaped structure and passes through two through holes on the base 22 and is fixed to the base 22 by fastening bolts. A mounting plate 32 is installed on the top surface of the fixing seat 31 by screws. A synchronous wheel 33 is rotatably provided on the mounting plate 32. A lower top that rotates synchronously with the synchronous wheel 33 is also installed on the top of the synchronous wheel 33.

[0050] A fixed support is installed on one of the vertical side walls of the base 22 by screws, and a rotating shaft 25 passes through the fixed support and is in rotational contact with it. A synchronous wheel 33 is also installed on the rotating shaft 25 and is rotated and adjusted synchronously with it. The two synchronous wheels 33 are located at the same horizontal height, and a synchronous belt is connected between the two synchronous wheels 33.

[0051] It needs to be further explained that the synchronous wheel 33 on the rotating shaft 25 is driven to rotate, and with the help of the synchronous belt, the synchronous wheel 33 on the fixed seat 31 is driven to rotate together, thereby realizing the rotation of the lower center, so that the lower center can cooperate with the upper center to synchronously drive the guide strip tool to be measured fixed between the two to rotate and adjust.

[0052] like Figure 2-3 as well as Figure 5 As shown, the adjusting member 4 includes a lifting seat 1 41, a mounting plate 2 42 and a synchronous wheel 2 43;

[0053] A mounting hole is provided on the lifting seat 41, and a guide piece 411 is fixed between the inner walls of the mounting hole by screws. A connecting sleeve 412 with an I-shaped structure is also passed through the lifting seat 41, and the connecting sleeve 412 is in rotational contact with the lifting seat 41. The rotating shaft 25 passes through the connecting sleeve 412 and the two are connected and rotated synchronously. A synchronous wheel 2 43 that rotates synchronously therewith is also installed on the connecting sleeve 412. The synchronous wheel 2 43 is located below the lifting seat 41, and a mounting plate 2 42 is installed on the bottom wall of the lifting seat 41 by screws. A synchronous wheel 2 43 is also rotatably provided on the bottom wall of the mounting plate 2 42. An upper top that rotates synchronously therewith is also installed at the bottom of the synchronous wheel 2 43. The two synchronous wheels 2 43 are located at the same horizontal height, and a synchronous belt is also connected between the two synchronous wheels 2 43.

[0054] The screw rod 24 penetrates through the guide piece 411 and is threadedly coupled thereto, and the side walls of the lifting seat 41 are also slidably adjusted along the inner walls of the through holes on both sides.

[0055] In addition, replaceable top heads can be installed on both the upper top and the lower top in a threaded connection manner.

[0056] It needs to be further explained that the vertical movement of the lifting seat 41 is controlled by the transmission effect of the screw 24 on the guide piece 411, thereby driving the upper center point to rise and fall and adjust its position, and the height position of the lifting seat 41 is controlled according to the length of the guide strip tool to be measured, so that it cooperates with the lower center point to fix the guide strip tool between the two. In addition, the connecting sleeve 412 is driven to rotate by the rotating shaft 25, so that the synchronous wheel 2 43 on the connecting sleeve 412 drives the synchronous wheel 2 43 on the lifting seat 41 to rotate and adjust together through the synchronous belt, thereby realizing the rotation of the upper center point, so that the upper center point can cooperate with the lower center point to synchronously drive the guide strip tool to be measured fixed between the two to rotate and adjust.

[0057] like Figure 2-3 as well as Figure 6 As shown, the measuring assembly 5 includes a lifting seat 2 51, a guide frame 52, a measuring bridge and a guide seat 54;

[0058] A side seat connected to the lifting seat 2 51 and in a "Y" shape is provided on one side wall thereof. The side seat is slidably arranged along the inner walls of the through holes on both sides. The rotating shaft 1 25 passes through the side seat and is in rotational contact with it. A guide seat 54 is fixed to the other end of the side seat by screws. The screw rod 26 passes through the guide seat 54 and is threadedly coupled thereto.

[0059] The guide frame 52 is arranged in an "L"-shaped structure, and a guide block is welded on the side wall of the guide frame 52 facing the lifting seat 2 51. A fixing groove is opened on the lifting seat 2 51 along its length direction, and a screw rod 3 is rotatably arranged in the fixing groove. A rotary motor (not shown in the figure) is installed at one end of the screw rod 3 in the lifting seat 2 51, and the screw rod 3 passes through the guide block and cooperates with it in threaded transmission.

[0060] Among them, two groups of measuring bridges are installed on the guide frame 52, and each group of measuring bridges includes a measuring rod 53, a measuring head 531 and a mounting seat 532. The measuring rod 53 is fixedly installed between the inner walls of the guide frame 52, the measuring head 531 is installed on one end of the measuring rod 53 and is set toward the guide strip tool to be measured, and the mounting seat 532 is installed on the other end of the measuring rod 53, and a micrometer (not shown in the figure) is installed on the mounting seat 532.

[0061] In addition, a detection head is provided below the two groups of measuring bridges. The detection head is mounted on the bottom wall of the guide frame 52 by means of screws. The detection head collects information by collecting images to determine the position of the blade.

[0062] It should be further explained that the vertical movement of the lifting seat 2 51 is synchronously controlled by the driving action of the screw 26 on the guide seat 54. When it is adjusted to a position relative to the blade edge, the rotary motor is started to make the guide frame 52 start to move along the length direction of the lifting seat 2 51, so that the measuring head 531 gradually approaches and contacts the blade edge, and then the blade adjustment screw is adjusted while observing the changes in the micrometer pointer to adjust the size of the blade edge to the desired size.

[0063] like Figure 2-3 as well as Figure 7-8 As shown, the driving assembly 6 includes a shaft seat 61, a worm gear 1 62, a worm gear 2 63, a worm 64, a swing arm 65 and a synchronous wheel 3 66;

[0064] Two relatively arranged shaft seats 61 are installed on the top surface of the base 22 by screws, and a rotating motor 1 is installed on the side wall of one of the shaft seats 61 by screws, and a rotating shaft 2 611 is installed on the output end of the rotating motor 1, and the rotating shaft 2 611 rotates between the shaft seats 61 on both sides, and two relatively arranged swing arms 65 are fixed on the shaft seat 61 by screws, and a rotating motor 2 is installed on the side wall of one of the swing arms 65 by screws, and a worm 64 is rotatably arranged between the side walls of the two swing arms 65, and one end of the worm 64 is connected and fixed to the output end of the rotating motor 2.

[0065] The worm gear 62 is arranged at the top of the screw rod 24. There are no threads at the top and bottom ends of the screw rod 24. A limit plate 1 is installed between the inner walls near the top of the screw rod 24 by screws (the limit plate 1 is a circular electromagnet that can be directly powered on to generate suction). A connecting shaft 661 runs through the middle of the limit plate 1. The bottom end of the connecting shaft 661 is in an "I"-shaped structure (the connecting shaft 661 is made of iron material, and suction can be generated between the connecting shaft 661 and the limit plate 1) and can rotate between the upper surface and the lower surface of the limit plate 1. When there is suction between the connecting shaft 661 and the limit plate 1, the connecting shaft 661 is connected to the limit plate 1 as a whole. The top end of the connecting shaft 661 is connected to the worm gear 62 as a whole by screws, and a synchronous wheel 3 66 that rotates synchronously with it is also installed on the connecting shaft 661.

[0066] A limit plate 2 is installed between the inner walls near the top of the rotating shaft 25 by screws (the limit plate 2 is also a circular electromagnet, which can be directly powered on to generate suction), and a connecting shaft 661 also runs through the middle of the limit plate 2. The connecting shaft 661 is configured in the same manner as the connecting shaft 661 connected to the worm gear 62, and suction can also be generated between the connecting shaft 661 and the limit plate 2, and the "I"-shaped structure at the bottom end of the connecting shaft 661 rotates between the upper surface and the lower surface of the limit plate 2, and when there is suction between the connecting shaft 661 and the limit plate 2, the two are connected as one, and the worm gear 2 63 is fixed to the top of the connecting shaft 661 by screws, and a synchronous wheel 3 66 that rotates synchronously with it is also installed on the connecting shaft 661, and a synchronous belt is installed between the synchronous wheels 3 66 on both sides.

[0067] The worm gear 1 62 and the worm gear 2 63 are always mirror-symmetrical about the vertical center line of the rotating shaft 2 611 .

[0068] It needs to be further explained that if Figure 7As shown, at this time, the worm 64 is in a state of meshing with the worm wheel 1 62. In this state, there is suction between the limit plate 1 and the corresponding connecting shaft 661, so that the two are connected as a whole and rotate synchronously with the screw 1 24, while there is no suction between the limit plate 2 and the corresponding connecting shaft 661, so that the synchronous wheel 3 66 on the connecting shaft 661 and the worm wheel 2 63 can only rotate and adjust with the synchronous wheel 3 66 on the other side under the action of the synchronous belt 3. With the start of the rotating motor 2, the worm 64 starts to drive the worm wheel 2 63, so that the worm wheel synchronously drives the screw 1 24 to rotate and controls the height position of the adjusting member 4. When the guide tool to be measured is fixed by the upper and lower centers, the rotating motor 2 is paused. Subsequently, the rotating motor 1 is started to control the swing arm 65 to rotate 180 degrees to the side where the worm wheel 2 63 is located and then stop. After stopping, at this time, due to the previous worm wheel 2 6 With the synchronous movement of the worm wheel 1 62, when the worm 64 moves to one side of the worm wheel 2 63, it is in meshing state with the worm wheel 2 63, and suction is generated on the limit plate 2, so that suction is generated between the limit plate 2 and the corresponding connecting shaft 661 and the limit plate 2 is connected as a whole. At the same time, the suction between the limit plate 1 and the corresponding connecting shaft 661 disappears, and the two are no longer synchronized, so that the synchronous wheel 3 66 on the connecting shaft 661 and the worm wheel 1 62 can only rotate and adjust with the synchronous wheel 3 66 on the other side under the action of the synchronous belt 3. Subsequently, the rotating motor 2 is started again, so that the worm 64 controls the rotation of the worm wheel 2 63, and at the same time controls the synchronous adjustment of the worm wheel 1 62 through the synchronous belt 3, but does not drive the rotation of the screw 1 24. The rotation of the worm wheel 2 63 synchronously drives the rotation output of the rotating shaft 1 25, thereby controlling the unilateral drive of the worm wheel 1 62 and the worm wheel 2 63.

[0069] The transmission assembly 7 includes an input member 71 and an output member 72, wherein the input member 71 is a disc structure and the output member 72 is a regular polygon structure;

[0070] A driving disk 711 and a fixed shaft 712 that rotate synchronously with the input member 71 are installed in the middle of the top surface of the input member 71. The rotating shaft 25 passes through the middle position of the input member 71 and is connected to it as a whole. The two move synchronously. The rotating shaft 25 also passes through the middle position of the driving disk 711, but the two are only relatively synchronized due to the existence of the input member 71.

[0071] An arc groove is formed on each side of the output member 72, and grooves are formed between adjacent arc grooves. The output member 72 is installed at a position close to the top end of the screw rod 26 and rotates and adjusts synchronously therewith.

[0072] The driving disk 711 is arranged in a "crescent" shape, and the outer surface of the driving disk 711 (excluding the concave outer surface) facing outward can rotate in contact with the arc groove, and the fixed shaft 712 can also slide in contact with it along the inner wall of the groove in a rotating state.

[0073] It should be further explained that when the worm gear 2 63 starts to rotate, it synchronously drives the rotating shaft 1 25 to rotate, so that the input member 71 on the rotating shaft 1 25 moves synchronously, and then also drives the circular motion of the driving disk 711 and the fixed shaft 712. With the movement of the driving disk 711 and the fixed shaft 712, the arc groove and the groove are also staggered in the rotation process to respectively contact with the corresponding driving disk 711 and the fixed shaft 712. When the fixed shaft 712 begins to enter the groove, the driving disk 711 and the arc groove begin to break away from the state of rotational contact. At the same time, the movement of the fixed shaft 712 also drives the rotation of the output member 72. When the fixed shaft 712 rotates out of the groove from the other side, the driving disk 711 happens to enter the state of rotational contact with the arc groove again, thereby reciprocatingly realizing the intermittent rotation output of the output member 72, so that with the rotation of the output member 72, the synchronous rotation of the screw 2 26 is driven, and the output member 72 is rotated. Under the threaded transmission action of the guide seat 54 and the screw rod 26, the vertical movement of the lifting seat 2 51 is controlled, and the worm gear 2 63 drives the rotating shaft 1 25 to rotate, so that the synchronous wheel 1 33 and the synchronous wheel 2 43 on the rotating shaft 1 25 rotate synchronously, so that the upper center and the lower center drive the fixed guide bar tool to rotate synchronously. During the rotation of the guide bar tool, the detection head continuously collects information to obtain the position of the blade edge. After each rotation of the guide bar tool, the lifting seat 2 51 adjusts the collection position under the action of the output member 72 and the screw rod 26, and stops when the detection head obtains the blade edge. At this time, by starting the rotary motor, the screw rod 3 rotates, and the guide frame 52 is controlled to drive the measuring head 531 to move to the blade edge position and finally contact it. Subsequently, the operator manually adjusts the adjustment screw of the blade while observing the changes in the meter pointer to adjust the blade edge size to the desired size.

[0074] Working principle:

[0075] First, take two top heads and install them on the upper top and the lower top respectively, manually place the guide bar tool to be tested vertically on the lower top, make the worm 64 mesh with the worm wheel 62, and the screw 24 rotates with the worm wheel 62, thereby controlling the lifting seat 41 of the adjustment member 4 to move to the top side of the guide bar tool until the upper top and the lower top clamp and fix the guide bar tool;

[0076] Next, the position of the worm 64 is switched to mesh with the worm gear 2 63, so that the rotating shaft 1 25 is synchronized with the worm gear 2 63, and the screw 2 26 intermittently rotates with the rotation of the rotating shaft 1 25, thereby controlling the measuring component 5 to start moving and adjusting from top to bottom along the vertical direction. During the movement, the rotating shaft 1 25 is first used to realize the rotation adjustment of the guide cutter. After the rotation, the measuring component 5 is adjusted downward under the action of the screw 2 26, so that the position of the blade edge is automatically found by first rotating and then adjusting the position downward.

[0077] Then, after finding the position of the blade edge, the guide frame 52 is moved to make the measuring bridge contact with the blade edge, and the micrometer is adjusted to zero. Subsequently, the operator manually adjusts the adjustment screw of the blade while observing the changes in the indicator pointer to adjust the blade edge size to the desired size. After the adjustment is completed, the reset device can be removed from the guide bar tool.
