Description

Technical Field

[0001] This invention relates to the field of guide rail processing technology, and more specifically to a guide rail milling apparatus and method. Background Technology

[0002] As a core guiding component of machine tools and automated equipment, the machining accuracy of guide rails directly affects the stability and positioning accuracy of the equipment. Currently, guide rail milling is mostly carried out using dedicated milling machine tools, which use multiple power heads to complete the forming of the top, sides, and web of the rail. This method significantly improves production efficiency and automation compared to traditional manual processing and has become the mainstream processing method in the industry.

[0003] Chinese patent CN112024958B discloses a special milling machine tool for guideways, including a bed, a power head assembly, a hydraulic clamp, and a cooling and chip removal device. The power head assembly and hydraulic clamp are both mounted on the bed. The power head assembly includes a top-mounted milling power head, two sets of side-mounted milling power heads for the guide head, and two sets of web-mounted milling power heads. The top-mounted milling power head is mounted on the upper part of the bed gantry, and the two sets of top-mounted milling power heads are respectively mounted on both sides of the bed gantry. Web-mounted milling power heads are installed on both sides in front of the bed gantry along the feed direction. However, this device still has the following problems during use:

[0004] The milling cutter follows the power head assembly through a unidirectional feed machining mode. In the initial stage of machining, this can easily lead to uneven force on the guide surface of the milling cutter and poor flatness of the finished product. At this time, the whole machine needs to reciprocate, which not only consumes a lot of energy but also affects the machining accuracy. Furthermore, after the milling is completed, the machine still needs to be stopped for manual inspection or offline inspection, which not only prolongs the machining cycle but also makes it impossible to provide real-time feedback on the milling quality, which can easily result in batches of defective products.

[0005] Based on this, the present invention designs a guide rail milling processing device and method to solve the above problems. Summary of the Invention

[0025] To better achieve the objectives of this invention, this invention also provides a method for using a guide rail milling apparatus, comprising the following steps:

[0026] Step 1: The workpiece to be milled using V-shaped guideways is moved to the top of the machine tool slot plate using a hoisting device. Based on the size of the workpiece and the machining position, the adjustable bottom support mechanism is placed at the corresponding position at the top of the machine tool slot plate, and the workpiece is clamped.

[0027] Step 2: Start the mobile grinding mechanism. The mobile grinding mechanism moves unidirectionally along the V-shaped guide rail setting direction and grinds the bottom groove of the guide rail of a set of V-shaped guide rails on the workpiece.

[0028] Step 3: While the mobile grinding mechanism moves along the V-shaped guide rail setting direction, the reciprocating milling mechanism moves synchronously with the mobile grinding mechanism and performs milling operations on the guide rail surface along the bottom groove of the guide rail; during the movement of the reciprocating milling mechanism following the mobile grinding mechanism, the reciprocating milling mechanism performs reciprocating milling along the bottom groove of the guide rail to mill the guide rail surface of a set of V-shaped guide rails of the workpiece.

[0029] Step 4: When the mobile grinding mechanism and the reciprocating milling mechanism move along the V-shaped guide rail setting direction, the lifting component controls the synchronous adjustment component, the first conformal detection component and the second conformal detection component to move downward. The first conformal detection component and the second conformal detection component contact the guide rail surface of the set of V-shaped guide rails that have been milled. At the same time as the first conformal detection component and the second conformal detection component move along the V-shaped guide rail setting direction, the first conformal detection component and the second conformal detection component move along the inclined direction of the guide rail surface of the V-shaped guide rail, and the movement trajectory of the first conformal detection component and the second conformal detection component is a wavy line. The first conformal detection component and the second conformal detection component perform scanning detection along the wavy line trajectory, and compare the detected data with the preset guide rail surface flatness parameters. Based on the comparison results, it is determined whether the position of the mobile grinding mechanism and the reciprocating milling mechanism needs to be adjusted. The mobile grinding mechanism and the reciprocating milling mechanism are reset to the position of the guide rail surface of the set of V-shaped guide rails that needs to be milled a second time for secondary milling.

[0030] Step 5: After the flatness of the guide rail surface is judged, the first conformal detection component and the second conformal detection component detect the inclination of the guide rail surface and determine whether the machining inclination of the two guide rail surfaces of the V-shaped guide rail is the same. Based on the comparison results of the two guide rail surfaces, it is determined again whether the moving grinding mechanism and the reciprocating milling mechanism need to be reset to the position of the guide rail surface of a set of V-shaped guide rails that needs to be milled twice for secondary milling.

[0031] Step 6: Repeat steps 2-5 to mill another set of V-shaped guide rails on the workpiece.

[0032] Compared with the prior art, the advantages of this invention are as follows: 1. The workpiece to be milled using V-shaped guideways is moved above the machine tool slot plate by a hoisting device. Then, the operator places the adjustable bottom support mechanism at the corresponding position at the top of the machine tool slot plate according to the size of the workpiece and the processing position. If part of the adjustable bottom support mechanism is located above the slot of the machine tool slot plate, the contact area between the adjustable bottom support mechanism and the machine tool slot plate can be changed, and the slot below the adjustable bottom support mechanism can be blocked, avoiding the lower end of the adjustable bottom support mechanism from being suspended, thereby forming a continuous support surface. This not only reduces the extra workload of the operator needing to take shims to place under the support, but also reduces the need for secondary adjustment of the support height, reduces the workpiece clamping time, and improves the efficiency of V-shaped guideway milling.

[0033] 2. After the workpiece clamping is completed, the mobile grinding mechanism is activated. It moves unidirectionally from right to left, grinding the guide rail groove on the workpiece surface. This facilitates the subsequent reciprocating milling mechanism's V-shaped guide rail milling operation, using the guide rail groove as a reference. The pre-ground guide rail groove also reduces the probability of tool breakage during subsequent milling, thus improving milling quality. As the mobile grinding mechanism moves along the V-shaped guide rail direction, the reciprocating milling mechanism moves synchronously, milling the guide rail surface along the guide rail groove. Since this is the initial stage of processing, most of the machining allowance needs to be removed. During the movement of the reciprocating milling mechanism along with the mobile grinding mechanism, it also performs autonomous left-right reciprocating movements, increasing the speed of removing machining allowance and ensuring the rough milling accuracy of the guide rail surface, further improving the processing quality of the V-shaped guide rail milling.

[0034] 3. As the mobile grinding mechanism and reciprocating milling mechanism continue to move to the left, the lifting component controls the synchronous adjustment component, the first conformal detection component, and the second conformal detection component to move downwards. This causes the first and second conformal detection components to contact the guide rail surface on the right. At this point, the first and second conformal detection components will respectively perform flatness detection on the front and rear guide rail surfaces of the V-shaped guide rail. By comparing the flatness parameters with preset guide rail surface flatness parameters, it is determined whether the controller needs to adjust the mobile grinding mechanism and reciprocating milling mechanism back to the corresponding processing position of the workpiece for secondary milling. The first and second conformal detection components will maintain close contact with the guide rail surface to ensure the accuracy of the detection results. As the first and second conformal detection components move to the left along with the mobile grinding mechanism and reciprocating milling mechanism, the first and second conformal detection components... The conformal detection components also move up and down along the inclined direction of the guide rail surface, causing the contact points of the first and second conformal detection components with the guide rail surface to achieve a wavy trajectory. This replaces the traditional single-point, single-line detection, allowing for a large-scale scan of the guide rail surface, providing a more comprehensive reflection of its flatness and improving detection accuracy. Furthermore, by comparing the detection results of the first and second conformal detection components, it can be determined whether the machining inclination of the two guide rail surfaces before and after the V-shaped guide rail is the same. This not only ensures the diversity of guide rail surface condition detection but also further guarantees milling accuracy and quality. Moreover, when the preset guide rail surface angle and position change, the synchronous adjustment component will also drive the first and second conformal detection components to move simultaneously towards or away from each other, thereby reducing or increasing the distance between them. This adapts to V-shaped guide rail surfaces of different sizes, further improving the practicality and detection accuracy of the device. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0050] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-10 A guide rail milling processing device includes a machine tool slot plate 1, and also includes an integrated milling and grinding processing mechanism, a follow-up guide rail surface detection device 4, and an adjustable bottom support mechanism 5;

[0051] The integrated milling and grinding mechanism for forming V-shaped guideways on the surface of a workpiece is connected to the machine tool slot plate 1.

[0052] The integrated grinding and milling processing mechanism includes a mobile grinding mechanism 2 that moves along the workpiece processing direction to form the guide rail bottom groove and a reciprocating milling mechanism 3 that performs guide rail surface milling operation synchronously with the mobile grinding mechanism 2; the mobile grinding mechanism 2 is connected to the machine tool slot plate 1; the reciprocating milling mechanism 3 is connected to the mobile grinding mechanism 2.

[0053] The follow-up guide surface detection device 4, used to detect the milled guide surface, is connected to the reciprocating milling mechanism 3.

[0054] The follow-up guide rail surface detection device 4 includes a lifting component, a synchronous adjustment component, a first conformal detection component, and a second conformal detection component.

[0055] The lifting assembly is connected to the reciprocating milling mechanism 3; the synchronous adjustment assembly is connected to the lifting assembly; the first conformal detection assembly and the second conformal detection assembly are staggered left and right and are both connected to the synchronous adjustment assembly.

[0056] Multiple adjustable bottom support mechanisms 5 are installed on the machine tool slot plate 1 to provide more stable support for the bottom of the workpiece;

[0057] A controller is fixedly installed on the machine tool slot plate 1; the controller is connected to the mobile grinding mechanism 2, the reciprocating milling mechanism 3, the first conformal detection component, and the second conformal detection component;

[0058] In this invention, the workpiece to be milled using V-shaped guideways is moved above the machine tool slot plate 1 by a hoisting device. Based on the size of the workpiece and the machining position, the adjustable bottom support mechanism 5 is placed at the corresponding position on the upper end of the machine tool slot plate 1. If a portion of the adjustable bottom support mechanism 5 is located above the slot of the machine tool slot plate 1, the contact area between the adjustable bottom support mechanism 5 and the machine tool slot plate 1 is changed, and the slot below the adjustable bottom support mechanism 5 is blocked to prevent the lower end of the adjustable bottom support mechanism 5 from being suspended, thus forming a continuous support surface. This not only reduces the extra workload of operators needing to remove shims to place under the support, but also reduces the need for secondary adjustments to the height of the support, reduces the time required for workpiece clamping, and improves the efficiency of V-shaped guideway milling.

[0059] After the workpiece is clamped, the movable grinding mechanism 2 is started. At this time, the movable grinding mechanism 2 will move unidirectionally from right to left and perform grinding operations on the guide rail bottom groove of the workpiece surface. This makes it convenient for the subsequent reciprocating milling mechanism 3 to perform V-shaped guide rail surface milling operations on the workpiece with the guide rail bottom groove as the reference. In addition, the guide rail bottom groove that is ground first also reduces the probability of tool breakage when the subsequent reciprocating milling mechanism 3 mills the guide rail surface, thereby improving the milling quality.

[0060] As the mobile grinding mechanism 2 moves along the V-shaped guide rail, the reciprocating milling mechanism 3 also moves synchronously with the mobile grinding mechanism 2 and performs milling operations on the guide rail surface along the bottom groove of the guide rail. Since this is the initial stage of processing, most of the machining allowance of the workpiece needs to be removed. During the process of moving with the mobile grinding mechanism 2, the reciprocating milling mechanism 3 will also move back and forth autonomously, which improves the speed of removing the machining allowance of the workpiece, ensures the rough milling accuracy of the guide rail surface, and further improves the processing quality of V-shaped guide rail milling.

[0061] When the mobile grinding mechanism 2 and the reciprocating milling mechanism 3 move along the V-shaped guide rail, the lifting component will also control the synchronous adjustment component, the first conformal detection component and the second conformal detection component to move downward, so that the first conformal detection component and the second conformal detection component contact the guide rail surface, and respectively detect the flatness of the front and rear guide rail surfaces of the V-shaped guide rail, and compare it with the preset guide rail surface flatness parameters. Based on the comparison results, it is determined whether the controller needs to adjust the mobile grinding mechanism 2 and the reciprocating milling mechanism 3 to return to the corresponding processing position of the workpiece for secondary milling. The first conformal detection component and the second conformal detection component will keep in close contact with the guide rail surface, thereby ensuring the accuracy of the detection results.

[0062] As the first and second conformal detection components move to the left along with the mobile grinding mechanism 2 and the reciprocating milling mechanism 3, they also move up and down along the inclined direction of the guide rail surface. This allows the contact points between the first and second conformal detection components and the guide rail surface to achieve a wavy motion trajectory on the guide rail surface, replacing the traditional single-point single-line detection. This allows for a large-scale scan of the guide rail surface, providing a more comprehensive reflection of the flatness of the guide rail surface and improving detection accuracy.

[0063] Furthermore, the first conformal detection component and the second conformal detection component will also detect the tilt of the guide rail surface to determine whether the machining tilt of the two guide rail surfaces of the V-shaped guide rail is the same. Based on the comparison results of the two guide rail surfaces, it will be determined again whether the moving grinding mechanism 2 and the reciprocating milling mechanism 3 need to be reset to the position of the guide rail surface of a set of V-shaped guide rails that needs secondary milling for secondary milling. This not only increases the diversity of detection of the guide rail surface state, but also further ensures the milling accuracy and quality.

[0064] Furthermore, as the first and second conformal detection components move to the left along with the mobile grinding mechanism 2, the lifting component also controls the first and second conformal detection components to move upward along the guide rail surface, thereby changing the initial contact position between the first and second conformal detection components and the V-shaped guide rail surface, realizing multi-point detection of the guide rail surface, and further improving the detection accuracy and detection diversity of the V-shaped guide rail surface.

[0065] Then repeat the above operation to mill another set of V-shaped guide rails on the workpiece.

[0066] Furthermore, when the preset guide rail surface angle and position change, the synchronous adjustment component will also drive the first conformal detection component and the second conformal detection component to move simultaneously toward each other or toward each other, thereby reducing or increasing the distance between the first conformal detection component and the second conformal detection component, thus adapting to V-shaped guide rail surfaces of different sizes, further improving the practicality and detection accuracy of the device.

[0067] Example 2: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, the movable grinding mechanism 2 includes a moving component and a grinding component; the moving component is connected to the machine tool slot plate 1; the grinding component is connected to the moving component;

[0068] like Figures 1-3 As shown, the moving assembly includes a first lead screw slide module 21, a gantry frame 22, a second lead screw slide module 23, a third lead screw slide module 24, and a first support plate 25; the first lead screw slide module 21 is fixedly installed on the lower side of the machine tool slot plate 1; the gantry frame 22 is fixedly connected to the moving end of the first lead screw slide module 21; the second lead screw slide module 23 is fixedly installed on the upper left side of the gantry frame 22; the third lead screw slide module 24 is fixedly connected to the moving end of the second lead screw slide module 23.

[0069] The first support plate 25 is fixedly connected to the moving end of the third lead screw slide module 24; the first support plate 25 is connected to the grinding assembly; the reciprocating milling mechanism 3 is connected to the first support plate 25;

[0070] The moving ends of the first lead screw slide module 21, the second lead screw slide module 23 and the third lead screw slide module 24 are all equipped with bellows covers to block iron filings.

[0071] The controller is electrically connected to the first lead screw slide module 21, the second lead screw slide module 23, and the third lead screw slide module 24.

[0074] The first synchronous transmission component enables the output end of the first drive motor 27 to be connected to the grinding disc 29 via a transmission connection.

[0075] The first cleaning pipe 210 is fixedly installed on the upper end of the outer shell of the grinding disc 29; the first cleaning pipe 210 is connected to an external water pump through a pipeline.

[0076] The controller is electrically connected to the first drive motor 27;

[0077] In this invention, after the workpiece clamping operation is completed, the first lead screw slide module 21 controls the gantry 22 to move unidirectionally to the left, and the second lead screw slide module 23 controls the third lead screw slide module 24 and the first bearing plate 25 to move downward, so that the lower end of the grinding disc 29 moves to the preset guide rail bottom groove grinding position. Then, the first drive motor 27 drives the grinding disc 29 to rotate through the first synchronous transmission component to perform guide rail bottom groove grinding on the surface of the workpiece. In addition, the first cleaning pipe 210 continuously sprays grinding fluid to reduce the friction and wear between the grinding disc 29 and the workpiece surface, thereby extending the life of the grinding disc 29 and improving the surface finish of the workpiece.

[0078] Grinding the bottom groove of the guide rail by grinding the grinding disc 29 not only facilitates the subsequent reciprocating milling mechanism 3 to perform V-shaped guide rail surface milling on the workpiece with the bottom groove of the guide rail as the reference, but also reduces the probability of tool breakage when the subsequent reciprocating milling mechanism 3 mills the guide rail surface, thereby improving the milling quality.

[0083] like Figure 4 As shown, a heat sink for blocking iron filings is fixedly installed on the outer end of the second drive motor 32;

[0084] like Figures 4-8 As shown, the milling assembly includes a connecting plate 38, a third drive motor 39, a double-angle milling cutter 310, a second cleaning tube 311, and a second synchronous transmission assembly; the connecting plate 38 is fixedly installed on the right side of the front end of the driven transverse plate 35; the third drive motor 39 is fixedly installed on the upper rear side of the connecting plate 38; and the second synchronous transmission assembly is installed on the upper rear side of the connecting plate 38.

[0085] The double-angle end mill 310 is rotatably mounted below the front end of the connecting plate 38; one end of the second synchronous transmission assembly is fixedly connected to the output end of the third drive motor 39; the other end of the second synchronous transmission assembly is fixedly connected to the double-angle end mill 310.

[0086] The output end of the third drive motor 39 is connected to the double-angle milling cutter 310 via the second synchronous transmission component; the second cleaning tube 311 is fixedly installed on the right end of the follower housing 31.

[0087] Both the first synchronous transmission assembly and the second synchronous transmission assembly adopt a synchronous belt and synchronous pulley transmission assembly 28;

[0088] The follow-up housing 31 is connected to the lifting assembly;

[0089] In this invention, after the workpiece clamping operation is completed, the first lead screw slide module 21 controls the gantry 22 to move unidirectionally to the left, and the second lead screw slide module 23 controls the third lead screw slide module 24 and the first bearing plate 25 to move downward, so that the lower end of the grinding disc 29 moves to the preset guide rail bottom groove grinding position. Then, the first drive motor 27 drives the grinding disc 29 to rotate through the first synchronous transmission component to perform guide rail bottom groove grinding on the surface of the workpiece. In addition, the first cleaning pipe 210 continuously sprays grinding fluid to reduce the friction and wear between the grinding disc 29 and the workpiece surface, thereby extending the life of the grinding disc 29 and improving the surface finish of the workpiece.

[0090] As the grinding disc 29 moves along the V-shaped guide rail, the follower box 31 moves horizontally to the left along with the first bearing plate 25. At this time, the third drive motor 39 controls the double-angle milling cutter 310 to rotate through the synchronous belt and synchronous pulley transmission assembly 28 corresponding to the second synchronous transmission assembly, so that the double-angle milling cutter 310 performs milling operation on the guide rail surface along the bottom groove of the guide rail.

[0091] Since this is the initial stage of processing, most of the machining allowance of the workpiece needs to be removed. As the double-angle milling cutter 310 moves with the first support plate 25, the second drive motor 32 will also control the drive disk 33 to rotate, so that the drive roller 34 rotates synchronously with the drive disk 33. This causes the drive roller 34 to push the driven transverse plate 35 along the reciprocating guide plate 36 to move left or right along the limit groove 351. At this time, the double-angle milling cutter 310 will follow the driven transverse plate 35 and the reciprocating guide plate 36 to move left or right along the clearance groove 3111. This not only improves the speed of removing the machining allowance of the workpiece, but also ensures the rough milling accuracy of the guide rail surface, further improving the machining quality of V-shaped guide rail milling.

[0092] like Figures 4-6 As shown, the lifting assembly includes a second support plate 41, a cylinder slide module 42, and a first moving plate 43; the second support plate 41 is fixedly connected to the follower housing 31; the cylinder slide module 42 is fixedly installed at the front end of the second support plate 41; the first moving plate 43 is fixedly connected to the moving end of the cylinder slide module 42; the first moving plate 43 is connected to the synchronous adjustment assembly.

[0093] The controller is electrically connected to the cylinder slide module 42;

[0094] like Figures 4-6 As shown, the synchronous adjustment assembly includes a control motor 44, a drive gear 45, a driven rack 46, and an adjustment guide rail 47. The control motor 44 is fixedly mounted on the upper end of the first moving plate 43. The drive gear 45 is rotatably mounted on the lower end of the first moving plate 43. The output end of the control motor 44 is fixedly connected to the drive gear 45. The adjustment guide rail 47 is symmetrically fixedly mounted on the left and right sides of the lower end of the first moving plate 43. The driven rack 46 is slidably connected to the adjustment guide rail 47. The driven rack 46 is meshed with the drive gear 45.

[0095] The first conformal detection component and the second conformal detection component are respectively connected to the driven rack 46 on the right and left sides;

[0096] Both the first conformal detection assembly and the second conformal detection assembly include a misalignment plate 48, a buffer support assembly, and a surface detection assembly; the misalignment plate 48 is fixedly connected to the driven rack 46; the buffer support assembly is connected to the misalignment plate 48; and the surface detection assembly is connected to the misalignment plate 48.

[0097] The controller is electrically connected to the control motor 44;

[0098] like Figures 4-6 As shown, the buffer support assembly includes a support rod 49, a support ball 410, and a first reset spring 411. The support rod 49 is symmetrically and slidably installed on the left and right sides of the misalignment plate 48. The support ball 410, which is rotatably connected to the guide rail surface, is rotatably installed at one end of the support rod 49 near the guide rail surface. The first reset spring 411 is wound around the outer end of the support rod 49. One end of the first reset spring 411 is fixedly connected to the support rod 49. The other end of the first reset spring 411 is fixedly connected to the misalignment plate 48.

[0099] The first reset spring 411 ensures that the support rod 49 always tends to move downwards.

[0100] like Figures 4-6 As shown, the surface detection assembly includes a fourth lead screw slide module 412, an L-shaped plate 413, a moving guide rod 414, a second reset spring 415, an electronic dial indicator 416, and a second moving plate 417; the fourth lead screw slide module 412 is fixedly installed at one end of the two misaligned plates 48 that are close to each other.

[0101] The L-shaped plate 413 is fixedly connected to the moving end of the fourth lead screw slide module 412; the moving guide rod 414 is symmetrically fixedly installed on the inner top of the L-shaped plate 413; the second moving plate 417 is limited and slidably connected to the moving guide rod 414; a second reset spring 415 is wound around the moving guide rod 414; one end of the second reset spring 415 is fixedly connected to the second moving plate 417; the other end of the second reset spring 415 is fixedly connected to the moving guide rod 414.

[0102] The second reset spring 415 ensures that the second moving plate 417 always tends to move downwards.

[0103] The electronic dial indicator 416 is fixedly installed on the upper end of the second movable plate 417;

[0104] The electronic dial indicator 416 is connected to the controller for communication.

[0105] The second movable plate 417 is also fixedly equipped with an inclinometer (not shown in the figure) for monitoring the tilt angle of the guide rail surface.

[0106] The inclinometer is connected to the controller via communication.

[0107] In this invention, as the grinding disc 29 and the double-angle milling cutter 310 continue to move to the left, the cylinder slide module 42 controls the first moving plate 43 to move downward, so that the support ball 410 of the first conformal detection component and the second conformal detection component and the detection end of the electronic dial indicator 416 move towards the V-shaped guide rail surface. When the support ball 410 contacts the guide rail surface, it will move upward with the support rod 49. At this time, the support ball 410 will be tightly attached to the guide rail surface under the restoring force of the first reset spring 411.

[0108] After the detection end of the electronic dial indicator 416 contacts the guide rail surface, the second moving plate 417 moves upward along the moving guide rod 414, and under the restoring force of the second reset spring 415, the detection end of the electronic dial indicator 416 is tightly attached to the guide rail surface, thereby ensuring the accuracy of the detection results.

[0109] At this time, the electronic dial gauge 416 of the first conformal detection component and the second conformal detection component will respectively detect the flatness of the front and rear guide surfaces of the V-shaped guide rail, and determine whether secondary milling is required by comparing with the preset guide surface flatness parameters.

[0110] Furthermore, as the first conformal detection component and the second conformal detection component move to the left along with the first support plate 25 and the follower housing 31, the fourth lead screw slide module 412 of the first conformal detection component and the second conformal detection component will also pull the L-shaped plate 413 to move up and down along the guide rail surface. This allows the contact part between the detection end of the electronic dial indicator 416 and the guide rail surface to achieve a wavy linear motion trajectory on the guide rail surface, replacing the traditional single-point single-line detection, and performing a large-scale scan of the guide rail surface, more comprehensively reflecting the flatness of the guide rail surface and improving the detection accuracy.

[0111] Furthermore, by comparing the results of the inclinometer detection of the first conformal detection component and the second conformal detection component, it can be determined whether the machining inclination of the two guide rail surfaces before and after the V-shaped guide rail is the same, thereby determining whether secondary milling is required. This not only increases the diversity of the detection of the guide rail surface condition, but also further ensures the milling accuracy and quality.

[0112] Furthermore, the cylinder slide module 42 will also control the first moving plate 43 to move upward, thereby changing the initial contact position between the electronic dial indicator 416 detection end and the support ball 410 and the V-shaped guide rail surface, thereby realizing multi-point detection of the guide rail surface and further improving the detection accuracy of the V-shaped guide rail surface.

[0113] Furthermore, when the model of the double-angle milling cutter 310 is changed, causing the angle and position of the guide rail surface to change, the controller will start the control motor 44, causing the drive gear 45 to rotate. This causes the front and rear driven racks 46 to drive the misalignment plates 48 of the first conformal detection component and the second conformal detection component to move simultaneously along the adjusting guide rail 47 in a direction that is closer to or further away from each other. This reduces or increases the distance between the two electronic dial indicators 416 and adapts to V-shaped guide rail surfaces of different sizes, further improving the practicality of the device.

[0114] like Figure 9 and Figure 10 As shown, the adjustable bottom support mechanism 5 includes a magnetic chuck 51, a support screw 52, ​​a support sleeve 53, a drive ring 54, a force distribution plate 57, and a locking pin 58; the support screw 52 is fixedly installed in the middle of the upper end of the magnetic chuck 51; the support sleeve 53 is threadedly connected to the support screw 52.

[0115] The drive ring 54 is rotatably mounted on the upper end of the magnetic chuck 51; drive grooves 55 are symmetrically opened on the front and rear sides of the drive ring 54.

[0116] like Figure 9 As shown, the distance from one outer end of the driving groove 55 to the center point of the magnetic chuck 51 is greater than the distance from one inner end of the driving groove 55 to the center point of the magnetic chuck 51.

[0117] The magnetic chuck 51 has symmetrical telescopic grooves 56 on its front and rear sides; the force distribution plate 57 is slidably connected to the telescopic groove 56; the upper end of the force distribution plate 57 is rotatably mounted with a driven roller 510 that is rolledly connected to the inner wall of the drive inclined groove 55.

[0118] The drive ring 54, the magnetic chuck 51 and the force distribution plate 57 are all provided with locking grooves 59 that can be inserted into the locking pin 58;

[0119] In this invention, the workpiece to be milled by V-shaped guide rail is moved above the machine tool slot plate 1 by a hoisting device. Then, the operator places the magnetic chuck 51 at the corresponding position on the upper end of the machine tool slot plate 1 according to the size of the workpiece and the processing position.

[0120] If a portion of the adjustable bottom support mechanism 5 is located above the slot of the machine tool slot plate 1, remove the locking pin 58 from the locking slot 59 to release the rotation lock on the drive ring 54. Then rotate the drive ring 54 so that the drive inclined slot 55 pushes the force distribution plate 57 to extend outward along the telescopic slot 56, thereby expanding the contact area between the lower end of the magnetic chuck 51 and the machine tool slot plate 1. Then insert the locking pin 58 back into the locking slot 59 to restore the lock on the drive ring 54.

[0121] The groove of the machine tool slot plate 1 located below the magnetic chuck 51 is blocked, thereby preventing the lower end of the magnetic chuck 51 from being suspended, thus forming a continuous support surface. This not only reduces the extra workload of the operator having to take shims and place them under the support, but also reduces the need for secondary adjustment of the support height, reduces the workpiece clamping time, and improves the efficiency of milling the V-shaped guide rail of the workpiece.

[0122] Example 3: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, a method of using a guide rail milling apparatus includes the following steps:

[0123] Step 1: The workpiece to be milled by V-shaped guide rail is moved to the top of the machine tool slot plate 1 by the hoisting device. According to the size of the workpiece and the processing position, the adjustable bottom support mechanism 5 is placed at the corresponding position on the upper end of the machine tool slot plate 1 and the workpiece is clamped.

[0124] Step 2: Start the mobile grinding mechanism 2. The mobile grinding mechanism 2 moves unidirectionally along the V-shaped guide rail setting direction and grinds the bottom groove of the guide rail of a set of V-shaped guide rails on the workpiece.

[0125] Step 3: While the mobile grinding mechanism 2 moves along the V-shaped guide rail setting direction, the reciprocating milling mechanism 3 moves synchronously with the mobile grinding mechanism 2 and performs milling operation on the guide rail surface along the bottom groove of the guide rail; during the movement of the reciprocating milling mechanism 3 along the mobile grinding mechanism 2, the reciprocating milling mechanism 3 performs reciprocating milling along the bottom groove of the guide rail to mill the guide rail surface of a set of V-shaped guide rails of the workpiece.

[0126] Step 4: When the mobile grinding mechanism 2 and the reciprocating milling mechanism 3 move along the V-shaped guide rail setting direction, the lifting component controls the synchronous adjustment component, the first conformal detection component and the second conformal detection component to move downward. The first conformal detection component and the second conformal detection component contact the guide rail surface of the set of V-shaped guide rails that have been milled. While the first conformal detection component and the second conformal detection component move along the V-shaped guide rail setting direction, they also move along the inclined direction of the guide rail surface of the V-shaped guide rail. The movement trajectory of the first conformal detection component and the second conformal detection component is a wavy line. The first conformal detection component and the second conformal detection component perform scanning detection along the wavy line trajectory. The detected data is compared with the preset guide rail surface flatness parameters. Based on the comparison results, it is determined whether the position of the mobile grinding mechanism 2 and the reciprocating milling mechanism 3 needs to be adjusted. The mobile grinding mechanism 2 and the reciprocating milling mechanism 3 are reset to the position of the guide rail surface of the set of V-shaped guide rails that needs to be milled a second time for secondary milling.

[0127] Step 5: After the flatness of the guide rail surface is judged, the first conformal detection component and the second conformal detection component detect the inclination of the guide rail surface and determine whether the machining inclination of the two guide rail surfaces of the V-shaped guide rail is the same. Based on the comparison results of the two guide rail surfaces, it is determined again whether the moving grinding mechanism 2 and the reciprocating milling mechanism 3 need to be reset to the position of the guide rail surface of a set of V-shaped guide rails that needs to be milled twice for secondary milling.

[0128] Step 6: Repeat steps 2-5 to mill another set of V-shaped guide rails on the workpiece.
