Description

Technical Field

[0001] The invention relates to the technical field of machining machine tools, in particular to a machine tool used for drilling and tapping of guide rail ends. Background Art

[0002] Linear guides are used to support and guide moving parts to make reciprocating linear motion in a given direction. Depending on the nature of friction, the parts that support and guide the moving components to move along a certain trajectory are called guide pairs, also often referred to as guide rails. The motion trajectory of the moving parts can be straight, circular or curved. Rolling circular guides can be classified as rolling thrust bearings. Guide rails are a very important component in machines.

[0003] In the production process of linear guide rails, it is necessary to drill and tap the mounting holes of the linear guide rails. Tapping refers to using a certain torque to screw the tap into the bottom hole to be drilled to produce internal threads. The tapping machine is a machine tool that uses a tap to process internal threads. It is the most widely used internal thread processing machine tool.

[0004] The tapping machine in the prior art has application number 202222876846.4, authorization announcement number CN218800404U, and a Chinese patent named a CNC drilling and tapping machine. The above patent discloses a CNC drilling and tapping machine, including a base and a support seat fixed on the upper surface of the base, the upper surface of the support seat is fixedly connected to a placing table, the left and right sides of the upper surface of the placing table are fixedly connected to a fixed plate, the front and rear sides of the inner side of the fixed plate are fixedly connected to a sliding rod, the outer surface of the sliding rod is slidably covered with two groups of clamping plates, the inner side of the fixed plate is fixedly connected to a first hydraulic cylinder, and the output end of the first hydraulic cylinder is fixedly connected to the outer side of the clamping plate. The above patent enables the device to perform continuous drilling and tapping on the workpiece without changing the drill bit and tap in the middle, which further improves the drilling and tapping efficiency of the above patent.

[0005] Another example is the patent application number 201610376571.4, the authorization announcement number CN106002263B, and the name is a machine tool for drilling and tapping of guide rail ends. The above patent discloses a machine tool for drilling and tapping of guide rail ends, including a machine body, a hydraulic CNC three-divided dividing plate arranged at the upper end of the machine body, a workpiece initial positioning component, a drilling power head component and a tapping power head component. Three hydraulic centering clamps are arranged at the three-divided positions of the outer edge of the hydraulic CNC three-divided dividing plate. The workpiece initial positioning component, the drilling power head component and the tapping power head component are arranged on the side of the hydraulic CNC three-divided dividing plate corresponding to the positions of the three hydraulic centering clamps. The above patent can automatically complete the drilling and tapping of the guide rail end after clamping the workpiece, and has high production efficiency, low skill requirements for operators, and high processing quality.

[0006] Tapping machines such as those in the above-mentioned patents can meet the tapping needs of guide rails to a certain extent. However, in the actual working process, after the first guide rail to be tapped is installed at the established tapping station, the tapping component is slid downward to tap the guide rail. When the first guide rail to be tapped is completed, the guide rail needs to be disassembled from the tapping station before the next guide rail to be tapped can be installed, and the cycle repeats. In the prior art, the guide rail workpiece is generally installed manually at the tapping station, and after the tapping operation is completed, the fastening mechanism that fixes the guide rail workpiece needs to be disassembled before the tapped guide rail workpiece can be removed, or in order to reduce the workload, a robotic arm is used instead of manual labor to complete the disassembly and installation of the guide rail workpiece, but in fact the work procedure is not reduced, and it will increase production costs.

[0007] It can be seen from this that how to passively unlock the guide rail workpiece and eject the guide rail workpiece when the tapping component resets upward after a guide rail workpiece completes tapping, and how to drive the unloading of the guide rail workpiece that has completed the tapping operation during the loading stroke of the next guide rail to be tapped, is a technical problem that needs to be solved urgently.

[0014] Furthermore, a trigger portion is provided on the extension frame for driving the clamping plate away from the second workpiece, and the trigger portion includes a first trigger block fixedly connected to the sliding rod, and a second trigger block is fixedly connected to the extension frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: First station: When the hydraulic component drives the lifting plate to drive the tapping component to slide downward, the linkage mechanism drives the fastening block to fix the first workpiece during the stroke, and drives the material pulling mechanism to slide on the extension frame. During the downward sliding stroke of the lifting plate, the linkage mechanism drives the fastening block to slide toward the first workpiece, so that the first workpiece can be fixed by the fastening block to improve the stability of the guide rail workpiece during tapping. Moreover, during the downward sliding stroke of the lifting plate, the material pulling mechanism at this moment slides away from the frame, and at this moment the material pulling mechanism does not contact the guide rail workpiece, preparing to drive the second workpiece to slide on the extension frame, meeting the work needs.

[0020] Second station: When the tapping component has completed the tapping operation on the first workpiece inside the processing groove, it is necessary to use hydraulic components to drive the lifting plate to drive the tapping component to reset, so as to facilitate the tapping operation on the subsequent guide rail workpiece.

The reciprocating operation can improve the working efficiency of the machine tool.

[0021] By setting up a positioning mechanism, when the second workpiece enters the machining groove position, the fastening block fixes the second workpiece in the stroke in which the positioning mechanism drives the second workpiece to abut against the side of the machining groove close to the tapping component, thereby making the position of the guide rail workpiece entering one side of the machining groove more accurate. At this moment, there is no need to set up a separate measuring mechanism to measure the tapping size, thereby further improving the practicability of the machine tool.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

At this moment, the second workpiece 7 abuts against the first workpiece 6, driving the first workpiece 6 to unload.

[0042] Specifically, the machine tool for drilling and tapping the end of the guide rail includes a frame 1, and a support member is provided at the bottom of the frame 1 to support the operation, and an anti-skid pad is provided at the bottom of the support member to improve the stability of the machine tool during operation. Specifically, a lifting plate 2 is slidably connected to the frame 1 through a hydraulic member 3 on the frame 1, so that the lifting plate 2 can slide vertically. A tapping component 4 for tapping operation is installed on the lifting plate 2. Specifically, the tapping component 4 is a prior art, which includes a tapping motor, and a tapping drill bit for tapping operation is provided on the output end of the tapping motor. A servo mechanism is provided between the tapping component 4 and the lifting plate 2, so that the tapping component 4 can move along the X, Y, and Z axes, so that the tapping component 4 can tap the guide rail workpiece. A limited position unit is provided between the lifting plate 2 and the frame 1, so that the stability of the lifting plate 2 when sliding can be improved.

[0043] A processing groove 5 for processing the first workpiece 6 is provided on the frame 1, and a fastener 8 for fixing the workpiece is provided on the frame 1. The fastener 8 includes a fastening block 81 slidably connected to the frame 1. Therefore, the first workpiece 6 can be fixed by sliding the fastening block 81 on the frame 1, thereby improving the stability during the tapping operation, and further improving the tapping quality to meet work needs.

[0044] The fastening block 81 is connected to the lifting plate 2 through a linkage mechanism 10. Therefore, when the lifting plate 2 slides vertically downward, the fastening block 81 is driven to slide on the frame 1 through the linkage mechanism 10, thereby improving the working efficiency of the machine tool. There is no need to set up a separate fastening mechanism to fix the first workpiece 6 to be processed, and the use effect is better. The frame 1 is also provided with a jacking mechanism 11 for unloading the workpiece. The jacking mechanism 11 can eject the tapping workpiece after the tapping operation is completed to facilitate the unloading of the guide rail workpiece after tapping. The machine tool is also fixedly connected to an extension frame 9, and a second workpiece 7 is arranged on the extension frame 9. Specifically, the first workpiece 6 and the second workpiece 7 have the same structure. The first workpiece 6 is a guide rail workpiece located on one side of the processing groove 5, and the second workpiece 7 is a guide rail workpiece located on one side of the extension frame 9. When the first workpiece 6 is tapped and unloaded, the second workpiece 7 will slide to the position of the original first workpiece 6 and become the first workpiece 6, and the subsequent guide rail workpiece will be replaced as the second workpiece 7, and the cycle is repeated. A pulling mechanism for intermittently clamping the second workpiece 7 is also provided between the extension frame 9 and the frame 1, that is, when the pulling mechanism drives the second workpiece 7 to slide toward the side of the first workpiece 6, the pulling mechanism is in a fixed state with the second workpiece 7 at this moment. Conversely, when the pulling mechanism slides away from the frame 1, the pulling mechanism does not contact the second workpiece 7 at this moment, thereby preventing the pulling mechanism from bringing the second workpiece 7 back to its original position again.

[0045] Specifically, in the actual working process, as the hydraulic component 3 drives the lifting plate 2 to slide downward and upward, it can be specifically divided into two working positions:

[0046] First station: When the hydraulic component 3 drives the lifting plate 2 to drive the tapping component 4 to slide downward, the linkage mechanism 10 drives the fastening block 81 to fix the first workpiece 6 and drives the material pulling mechanism to slide on the extension frame 9. Before this work, first install the first workpiece 6 to be tapped in the processing groove 5, and then start the hydraulic component 3. The hydraulic component 3 will drive the lifting plate 2 to slide downward and drive the tapping component 4 to slide downward, preparing to tap the first workpiece 6. During the downward sliding stroke of the lifting plate 2, the linkage mechanism 10 drives the fastening block 81 to slide toward the first workpiece 6, so that the first workpiece 6 can be fixed by the fastening block 81 to improve the stability of the guide rail workpiece during tapping. Moreover, during the downward sliding stroke of the lifting plate 2, the material pulling mechanism slides away from the frame 1, and the material pulling mechanism does not contact the guide rail workpiece, preparing to drive the second workpiece 7 to slide on the extension frame 9 to meet the work needs.

[0047] Second station: When the hydraulic component 3 drives the lifting plate 2 to drive the tapping component 4 to slide upward, the linkage mechanism 10 drives the fastening block 81 to unlock the first workpiece 6, and the first workpiece 6 is ejected by the lifting mechanism 11. The pulling mechanism drives the second workpiece 7 to slide, and the second workpiece 7 abuts against the first workpiece 6 to drive the first workpiece 6 to unload. That is, when the tapping component 4 has completed the tapping operation of the first workpiece 6 inside the processing groove 5, it is necessary to use the hydraulic component 3 to drive the lifting plate 2 to drive the tapping component 4 to reset, so as to facilitate the tapping operation of the subsequent guide rail workpiece. When the lifting plate 2 slides upward, the linkage mechanism 10 drives the fastening block 81 to slide to the side away from the first workpiece 6, that is, the fastening block 81 unlocks the first workpiece 6, and the fastening block 81 will drive the lifting mechanism 11 to move during the unlocking of the first workpiece 6. The lifting mechanism 11 will eject the first workpiece 6 after the processing is completed from the inside of the processing groove 5, thereby facilitating the unloading of the first workpiece 6. Furthermore, in the stroke after the jacking mechanism 11 ejects the first workpiece 6 from the inside of the processing groove 5, the pulling mechanism fixes the second workpiece 7 and drives the second workpiece 7 to slide on the extension frame 9 toward the side of the frame 1, and after the second workpiece 7 abuts against the first workpiece 6 after tapping, at this moment, with the continuous movement of the pulling mechanism, the second workpiece 7 is used to push the first workpiece 6 off the ejection mechanism, thereby facilitating the unloading of the first workpiece 6 and the loading of the second workpiece 7, that is, the second workpiece 7 is located on the jacking mechanism 11, and as the lifting plate 2 moves downward, the jacking mechanism 11 will drive the second workpiece 7 to slide downward, so that the second workpiece 7 is installed in the processing groove 5, and the second workpiece 7 is fixed by the subsequent fastening block 81, and the second workpiece 7 is fixed by the fastening block 81 to improve the stability of the guide rail workpiece during tapping.

[0048] The above operation process is repeated in a cycle, thereby improving the working efficiency of the machine tool.

[0049] In the embodiment provided by the present invention, a conveying assembly 22 is provided on one side of the extension frame 9 away from the frame 1, wherein the conveying assembly 22 is a prior art, and is used to convey the guide rail workpiece to be processed, and with the continuous operation of the conveying assembly 22, the guide rail components to be processed can be continuously conveyed to the original state of the pulling mechanism, and when the lifting plate 2 slides upward, the pulling mechanism will drive the guide rail components to slide to the side close to the processing groove 5, so as to realize the automatic loading and unloading of the machine tool. Specifically, a unloading frame 23 is provided on one side of the machine tool, and a plurality of groups of unloading rollers are provided on the unloading frame 23, and the plurality of groups of unloading rollers are in an inclined state, so as to facilitate the unloading of the processed guide rail workpiece.

[0050] In the embodiment provided by the present invention, the linkage mechanism 10 includes a linkage rod 103 rotatably connected to the frame 1, a first linkage gear 102 is installed on the linkage rod 103, and a first linkage rack 101 is fixedly connected to the lifting plate 2, and the first linkage rack 101 is meshed with the first linkage gear 102; a second linkage gear 105 is also installed on the linkage rod 103, and a second linkage rack 104 is fixedly connected to the fastening block 81 through a power plate 83, and the second linkage gear 105 is meshed with the second linkage rack 104, and a connecting plate 82 is fixedly connected to the fastening block 81, that is, the fastening block 81 slides on the frame 1 through the connecting plate 82 to achieve sliding, and the power plate 83 is fixedly connected to the fastening block 81 through the connecting plate 82 to meet the working needs. More specifically, the gear rack in the above-mentioned linkage mechanism 10 needs to adjust the number of teeth and the transmission ratio according to the working environment, which will not be repeated here. Therefore, during use, when the lifting plate 2 slides downward, the lifting plate 2 drives the first linkage rack 101 and the first linkage gear 102 to drive the linkage rod 103 to rotate, so that the power plate 83 can be driven to slide on the frame 1 through the cooperation of the second linkage gear 105 and the second linkage rack 104, and then the fastening block 81 can be driven to slide through the connecting plate 82, so that the fastening block 81 fixes the guide rail workpiece to improve the stability of the guide rail workpiece during tapping, and the use effect is better.

[0051] In the embodiment provided by the present invention, the lifting mechanism 11 includes a power frame 111 vertically slidably connected to the inside of the frame 1, wherein a limiting unit is provided between the power frame 111 and the frame 1, so as to improve the stability of the power frame 111 when it slides vertically. A driving screw 112 is rotatably connected to the frame 1, and the driving screw 112 is threadedly connected to the power frame 111. Therefore, when the driving screw 112 rotates, the power frame 111 is mobilized to slide vertically inside the frame 1, so as to facilitate the ejection of the processed guide rail workpiece and facilitate the unloading of the processed guide rail workpiece. A lifting gear 113 is installed on the driving screw 112, and a lifting rack 114 is fixedly connected to the second linkage rack 104, and the lifting rack 114 is meshed with the lifting gear 113, that is, when the second linkage rack 104 slides, it drives the fastening block 81 to fix the guide rail workpiece, which will drive the lifting rack 114 to slide, and then drive the lifting gear 113 to rotate, thereby driving the driving screw 112 to rotate. A lifting plate 115 is installed on the lifting frame through an elastic member 116. Specifically, by setting the elastic member 116, there is a certain buffer between the lifting plate 115 and the guide rail workpiece to meet the working needs. Therefore, during use, when the lifting plate 2 slides upward, the linkage mechanism 10 drives the fastening block 81 to slide away from the guide rail, and the second linkage rack 104 slides, which drives the lifting rack 114 to slide, and then drives the lifting gear 113 to rotate, thereby driving the driving screw 112 to rotate, and then drives the power frame 111 to slide upward through the driving screw 112, and ejects the first workpiece 6 located inside the processing groove 5. Preferably, a positioning unit is provided on the frame 1, that is, when the lifting plate 115 slides upward for a certain stroke, the positioning unit limits the lifting plate 115, and when the power frame 111 continues to slide upward, it will squeeze the elastic member 116, and at this moment, the lifting mechanism 11 can slide the processed guide rail workpiece upward to a predetermined position, so as to facilitate the unloading of the guide rail workpiece after subsequent processing, and meet the work needs. More specifically, a slide groove adapted to the guide rail workpiece is provided on the lifting plate 115 , so when the second workpiece 7 pushes the first workpiece 6 to unload, the first workpiece 6 is prevented from being offset during sliding, and the use effect is better.

[0052] In the embodiment provided by the present invention, a close block 13 is further provided on the side of the frame 1 away from the fastening block 81, and the close block 13 is adapted to the fastening block 81, so as to further improve the stability of the guide rail workpiece during tapping. A linkage portion 12 is provided between the close block 13 and the lifting rack 114, that is, when the fastening block 81 is away from the guide rail workpiece, the close block 13 is also driven away from the guide rail workpiece through the linkage portion 12. Specifically, the linkage part 12 includes a linkage shaft 121 rotatably connected to the frame 1, and a force gear 122 is fixedly connected to the linkage shaft 121, and a force rack 123 is fixedly connected to the bottom of the clamping block 13, and the force rack 123 and the lifting gear 113 are respectively engaged on both sides of the force gear 122. When the lifting rack 114 slides, it will drive the force gear 122 to rotate, and then the clamping block 13 can be driven to slide through the force rack 123, so that the clamping block 13 can be adapted to the movement of the fastening block 81, thereby further meeting the working needs.

[0053] In the embodiment provided by the present invention, the material pulling mechanism includes a bearing frame 14 slidably connected to the extension frame 9, and a power member 15 for driving the bearing frame 14 to slide is also provided between the extension frame 9 and the lifting mechanism 11. When the lifting mechanism 11 drives the first workpiece 6 to slide upward, the bearing frame 14 is driven by the power member 15 to drive the second workpiece 7 to slide on the extension frame 9, and the first workpiece 6 is driven to unload after the second workpiece 7 abuts against the first workpiece 6. Therefore, the material pulling mechanism does not need to set a separate driving source during the movement, but uses the power of the lifting plate 2 when it slides vertically to further meet the working needs. Clamping parts 16 are respectively provided on both sides of the bearing frame 14. Specifically, the clamping frame is a U-shaped frame to facilitate the installation of the second workpiece 7. More specifically, multiple sets of rollers are provided on the bearing frame 14, so as to minimize the friction between the bearing frame 14 and the second workpiece 7, and avoid driving the second workpiece 7 to slide in the opposite direction when the bearing frame 14 is reset. Therefore, when the carrier frame 14 is used, the carrier frame 14 can only be driven to slide after the clamping portion 16 fixes the second workpiece 7. On the contrary, when the carrier frame 14 transports the second workpiece 7 to the lifting plate 115, the carrier frame 14 unlocks and resets the second workpiece 7, and cannot drive the second workpiece 7 to slide in the opposite direction, thus meeting the working requirements. The clamping portion 16 includes a clamping plate 161 slidably connected to the carrier frame 14, and a mounting tube 163 is fixedly connected to the carrier frame 14, a sliding rod 162 fixedly connected to the clamping plate 161 is slidably connected inside the mounting tube 163, and a clamping spring 164 is arranged between the sliding rod 162 and the mounting tube 163, the elastic force of the clamping spring 164 drives the clamping plate 161 away from the mounting tube 163, and in the absence of external force, the elastic force of the clamping spring 164 drives the clamping plate 161 to abut against the second workpiece 7, and when the carrier frame 14 slides, it drives the second workpiece 7 to slide together. The mounting tube 163 is provided with a locking member for fixing the sliding rod 162. The locking member includes an insert rod 165, which is slidably connected to the mounting tube 163 through a through groove, and a locking spring 166 is provided between the insert rod 165 and the mounting tube 163, and a locking groove 167 is provided on the sliding rod 162, and the insert rod 165 is intermittently inserted into the locking groove 167, that is, when the insert rod 165 is not inserted into the locking groove 167, the elastic force of the clamping spring 164 drives the clamping plate 161 away from the mounting tube 163, at this time, without the action of external force, the elastic force of the clamping spring 164 drives the clamping plate 161 to abut against the second workpiece 7, and when the bearing frame 14 slides, it will drive the second workpiece 7 to slide together. When the insertion rod 165 is inserted into the locking groove 167, the sliding rod 162 drives the clamping plate 161 away from the second workpiece 7, and the clamping spring 164 is in a compressed state. When the supporting frame 14 slides, it cannot drive the second workpiece 7 to slide in the opposite direction, and the use effect is better.

[0054] In the embodiment provided by the present invention, a triggering part for driving the clamping plate 161 away from the second workpiece 7 is provided on the extension frame 9, and the triggering part includes a first triggering block 17 fixedly connected to the sliding rod 162, and a second triggering block 18 is fixedly connected to the extension frame 9. Specifically, the first triggering block 17 and the second triggering block 18 are both wedge-shaped blocks. When the first triggering block 17 abuts against the second triggering block 18, the sliding rod 162 is driven to slide into the installation tube 163. At this time, the insertion rod 165 is inserted into the locking groove 167 to fix the sliding rod 162. Therefore, during use, when the lifting plate 2 slides upward, and when the clamping plate 161 on the carrying frame 14 fixes the second workpiece 7, and the power member 15 drives the carrying frame 14 to slide toward the side close to the frame 1, it can drive the second workpiece 7 to slide on the extension frame 9 toward the side close to the frame 1. When the carrying frame 14 slides to a predetermined position, the first trigger block 17 abuts against the second trigger block 18. When the carrying frame 14 continues to slide, the sliding rod 162 is driven to slide toward the side close to the inside of the mounting tube 163 under the abutment of the first trigger block 17 and the second trigger block 18. At this moment, the sliding block overcomes the restriction of the locking spring 166 and continues to slide toward the inside of the mounting tube 163 until the insertion rod 165 is inserted into the locking groove 167 to fix the state of the sliding rod 162. At this moment, the clamping plate 161 is on the side away from the second workpiece 7, and cannot drive the second workpiece 7 to slide in the opposite direction, meeting the working needs.

[0055] In the embodiment provided by the present invention, the extension frame 9 is also provided with an unlocking part for driving the insertion rod 165 to slide out from the locking groove 167; the unlocking part includes an unlocking rod 19 fixedly connected to the extension frame 9, and the insertion rod 165 is provided with an unlocking groove 20. When the unlocking rod 19 is inserted into the unlocking groove 20, the insertion rod 165 slides out from the locking groove 167, and at this moment, the clamping spring 164 drives the clamping plate 161 to fix the second workpiece 7 during the elastic deformation recovery process. That is, when the lifting plate 2 slides downward, the power member 15 drives the material pulling mechanism to slide to the side away from the frame 1. During the sliding stroke of the carrying frame 14, the clamping plate 161 at this moment does not contact the second workpiece 7, so it can drive the carrying frame 14 to reset smoothly. When the supporting frame 14 slides to a predetermined position, the unlocking rod 19 will be inserted into the unlocking groove 20. As the supporting frame 14 continues to slide, the insertion rod 165 will slide out of the locking groove 167. During the recovery of the elastic deformation of the clamping spring 164, the clamping plate 161 will be driven to transport the subsequent conveying assembly 22 to the second workpiece 7 on the extension frame 9 and fix it again, so as to facilitate the subsequent re-loading of the second workpiece 7. This cycle is repeated, thereby improving the loading efficiency of the guide rail workpiece.

[0056] In the embodiment provided by the present invention, specifically, the power member 15 includes a power screw 151 rotatably connected to the extension frame 9, and the bearing frame 14 is threadedly connected to the power screw 151 through a threaded sleeve; and the second bevel gear 153 is installed on the driving screw 112, and the first bevel gear 152 is provided on the power screw 151, and the first bevel gear 152 is meshed with the second bevel gear 153, so when the linkage mechanism 10 drives the lifting rack 114 to slide, the driving screw 112 is driven to rotate through the lifting gear 113, and the power screw 151 is driven to rotate through the cooperation between the first bevel gear 152 and the second bevel gear 153, so as to facilitate the sliding of the bearing frame 14. More specifically, the maximum upward and downward sliding stroke of the power frame 111 will never affect the transmission between the first bevel gear 152 and the second bevel gear 153. Furthermore, the pitches of the threads in the power screw 151 can be designed according to work requirements, so that the upward sliding stroke of the lifting plate 2 can be satisfied and the carrying frame 14 can transport the second workpiece 7 to a predetermined position.

[0057] It is well known that the tapping positions of the guide rail workpieces of the same batch are generally at the same position. Therefore, as long as it can be ensured that each guide rail workpiece entering the processing groove 5 is in contact with the inner wall of the processing groove 5, and the guide rail workpiece is fixed by the fastening block 81, the accuracy of the tapping position of the guide rail workpieces of the same batch can be achieved. In the embodiment provided by the present invention, a positioning mechanism 21 is also provided on the frame 1. When the second workpiece 7 enters the processing groove 5 position, the fastening block 81 fixes the second workpiece 7 in the stroke, and drives the second workpiece 7 to abut against the side of the processing groove 5 close to the tapping component 4 through the positioning mechanism 21, so that the position of the guide rail workpiece entering one side of the processing groove 5 can be made more accurate, and there is no need to set up a separate measuring mechanism to measure the tapping size. The alignment mechanism 21 includes an alignment frame 211 slidably connected to the frame 1, an alignment rod 212 is fixedly connected to the alignment frame 211, and an installation block 213 is provided on the alignment rod 212, and a pressure groove 214 is provided on the installation block 213, and an alignment block 216 is fixedly connected to the fastening block 81, and the alignment block 216 and the pressure groove 214 are intermittently abutted; and a positioning spring 215 is provided between the installation block 213 and the frame 1. By providing the positioning spring 215, when it is not necessary to determine the state of the guide rail workpiece, the elastic force of the positioning spring 215 drives the alignment frame 211 away from the guide rail workpiece to avoid affecting the unloading of the guide rail workpiece. On the contrary, when the second workpiece 7 is ready to enter the processing groove 5, the fastening block 81 is driven by the linkage mechanism 10 to slide toward the side close to the second workpiece 7. During the sliding stroke of the fastening block 81, the positioning block 216 on the fastening block 81 abuts against the pressure groove 214, and the mounting block 213 and the positioning rod 212 are driven to slide toward the side close to the second workpiece 7 through the pressure groove 214, thereby driving the positioning frame 211 to abut against the second workpiece 7, and driving the second workpiece 7 to slide toward the processing groove 5, so that the second workpiece 7 abuts against the inner wall of the processing groove 5. Afterwards, as the fastening block 81 continues to slide, the second workpiece 7 that enters the processing groove 5 is fixed by the fastening block 81 and the clamping block 13, so as to facilitate the subsequent tapping operation.
