Description

Technical Field

[0001] The utility model relates to the technical field of straight machine needle processing, in particular to a device for opening holes in the body of a straight machine needle. Background Technique

[0002] Opening holes in the body of a straight machine needle is a processing technology used for directly processing holes on the surface of materials or workpieces. It is usually achieved by using a milling machine and appropriate tools.

[0003] When the traditional device for opening holes in the body of a straight machine needle is in use, it is necessary to disassemble and reinstall the tooling multiple times for the processing of a single set of needle bodies to achieve the processing of both sides of the needle body. This will increase the operation time and complexity, reduce the processing efficiency, and the disassembly and reinstallation of the tooling require multiple adjustments by the operator, increasing the workload of manual operation and also easily leading to errors.

[0004] Therefore, we propose a device for opening holes in the body of a straight machine needle. Content of the Utility Model

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a device for opening holes in the body of a straight machine needle.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme. A device for opening holes in the body of a straight machine needle includes a machine tool body composed of a Y-axis component, an X-axis component, and a Z-axis component. The front of the Z-axis component is connected with a machine head. A main shaft is arranged in the machine head. A milling cutter is connected to the lower end of the main shaft through a tool fixture. The upper end of the X-axis component is fixedly connected with a common plate workbench. A processing table is installed on the upper end of the common plate workbench. A lower tooling is arranged on the upper end of the processing table. Multiple groups of needle body installation grooves are equidistantly arranged on the front and back of the upper surface of the lower tooling. An upper tooling is arranged on the upper end of the lower tooling. The length, width, and thickness of the lower tooling and the upper tooling are the same. Two counterbore holes are opened in the middle of the top of the upper tooling. The upper tooling is fixed to the lower tooling through counterbore screws inside the counterbore holes. Two fixing bolts are vertically connected to the top of the processing table. Two round holes for the fixing bolts to pass through are opened in the lower tooling. Two fixing long grooves are opened on the upper end face of the upper tooling corresponding to the positions of the fixing bolts.

[0007] Preferably, multiple inverted T-shaped grooves are opened on the common plate workbench. A pressing groove is opened on the side wall surface of the processing table. A locking part is slidably connected in the inverted T-shaped groove. The upper end of the locking part is connected with a locking bolt. The outer circle of the locking bolt is connected with a fixing part in a penetrating manner. The lower end of the fixing part contacts the top surface of the common plate workbench, and the other end thereof contacts the inside of the pressing groove. The processing table is fixed to the upper end face of the common plate workbench by pressing down the fixing part through the fixation of the nut and the locking bolt.

[0008] Preferably, a plurality of feeding grooves are formed on the front and rear end faces of the upper tooling, and the distance between the feeding grooves is the same as the distance between the needle body mounting grooves on the lower tooling.

[0009] Preferably, a transverse positioning rod for positioning the tooling in the X direction is connected to the right side of the upper end face of the processing table.

[0010] Preferably, longitudinal positioning rods are fixedly connected to the front and rear positions of the upper end face of the processing table, and the distance between the longitudinal positioning rods is the same as the width of the lower tooling and the upper tooling.

[0011] Preferably, the height of the longitudinal positioning rod is aligned with the lowest point of the needle body mounting groove.

[0012] Beneficial effects

[0013] The utility model provides a straight machine needle body hole opening device. It has the following beneficial effects:

[0014] (1) This straight machine needle body hole opening device can realize opening holes for multiple groups of needle bodies at one time, and the fixed distance between the needle bodies is the same. A milling cutter with the same aperture as the hole to be opened is selected to process the hole. After processing the first group of needle bodies, the milling cutter is lifted, and the X-axis assembly drives the entire tooling to move horizontally by a specified distance to continue processing the second group of needle bodies. The processing path planning is simple and does not require complex programming of the tool processing path, improving production efficiency and processing accuracy.

[0015] (2) In this straight machine needle body hole opening device, the entire tooling is fixed by two sets of countersunk head threads between the lower tooling and the upper tooling. During programming, one side of all the needle bodies is processed to half of the depth, and then the entire tooling is removed by disassembling the two sets of nuts and turned over to form a state where the lower tooling is below and the upper tooling is above. Then, the tooling is fixed by connecting the nuts and the fixing bolts. At this time, the other side of all the needle bodies is opened to communicate with the first opening. By performing the hole opening processing step by step, the deformation of the needle body caused by heat concentration can be reduced, and the step-by-step processing can reduce the single cutting amount of the milling cutter, extend the service life of the milling cutter, and reduce the wear during the cutting process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: A device for opening holes in the needle body of a straight needle, as Figures 1 to 4 shown, including a machine tool body composed of a Y-axis component 1, an X-axis component 2, and a Z-axis component 3. A machine head 4 is connected to the front of the Z-axis component 3. A main shaft 5 is arranged in the machine head 4. The lower end of the main shaft 5 is connected with a milling cutter 6 through a tool fixture. The upper end of the X-axis component 2 is fixedly connected with a public version workbench 7.

[0027] On the upper end of the public workbench 7, a processing table 8 is installed. On the upper end of the processing table 8, a lower tooling 9 is provided. On the upper surface of the lower tooling 9, multiple groups of needle body mounting grooves 12 are equidistantly arranged in the front and back. On the upper end of the lower tooling 9, an upper tooling 10 is provided. The length, width, and thickness of the lower tooling 9 and the upper tooling 10 are all the same. At the middle of the top of the upper tooling 10, two counterbore holes 13 are opened. The upper tooling 10 is fixed to the lower tooling 9 through the countersunk head screws inside the counterbore holes 13. Vertically connected to the top of the processing table 8 are two fixing bolts 11. The lower tooling 9 is provided with two round holes for the fixing bolts 11 to pass through. At the positions corresponding to the fixing bolts 11 on the upper end face of the upper tooling 10, two fixing long slots 14 are opened.

[0028] During use, the lower tooling 9 is installed on the processing table 8 through the cooperation of the round holes and the fixing bolts 11. Then, multiple groups of straight needles to be drilled are placed in the needle body mounting grooves 12. Next, the upper tooling 10 is fixed above the lower tooling 9 in such a way that the fixing bolts 11 pass through the fixing long slots 14. At this time, the upper tooling 10 and the lower tooling 9 are pressed and fixed to each other through two countersunk head screws installed in the counterbore holes 13. Finally, the complete tooling formed by pressing the lower tooling 9 and the upper tooling 10 is fixed on the processing table 8 through the connection of two nuts and the fixing bolts 11. By processing in this way, multiple groups of needle bodies can be drilled at one time, and the fixed spacing of the needle bodies is consistent. A milling cutter 6 with the same aperture as the hole to be opened is selected to process the holes. After processing the first group of needle bodies, the milling cutter 6 is lifted. The X-axis assembly 2 drives the entire tooling to horizontally displace a specified distance, and then the second group of needle bodies can be processed continuously. The processing path planning is simple and does not require complex programming of the tool processing path, improving production efficiency.

[0029] The entire tooling is fixed by the lower tooling 9 and the upper tooling 10 through two sets of countersunk head threads. During programming, one side of all the needle bodies is processed to half of the depth. Then, the entire tooling is removed by disassembling two nuts and turned over, forming a state where the lower tooling 9 is below and the upper tooling 10 is above. Then, the tooling is fixed through the connection of the nuts and the fixing bolts 11. At this time, the other side of all the needle bodies is drilled to communicate with the first drilled hole. By performing the drilling process step by step, the deformation of the needle bodies caused by heat concentration can be reduced, and the step-by-step processing can reduce the single cutting amount of the milling cutter 6, extend the service life of the milling cutter 6, and reduce the wear during the cutting process.

[0030] Embodiment 2: On the basis of the above embodiment, as Figure 3As shown in the figure, multiple groups of inverted T-shaped grooves 18 are provided on the public workbench 7, and a pressing groove 22 is provided on the side wall surface of the processing table 8. A locking member 19 is slidably connected in the inverted T-shaped groove 18. The upper end of the locking member 19 is connected to a locking bolt 20. The outer circle of the locking bolt 20 is connected and fixed to a fixing member 21. The lower end of the fixing member 21 contacts the top surface of the public workbench 7, and the other end thereof contacts the inside of the pressing groove 22. By fixing the fixing member 21 with a nut to the locking bolt 20, the processing table 8 is fixed to the upper end surface of the public workbench 7 by downward extrusion.

[0031] Embodiment 3: On the basis of the above embodiment, as Figure 4 shown, multiple groups of feeding grooves 15 are provided on the front and rear end surfaces of the upper tooling 10, and the distance between the feeding grooves 15 is the same as the distance between the needle body mounting grooves 12 on the lower tooling 9.

[0032] After all the needle bodies are processed, by removing two sets of countersunk screws in the countersunk holes 13 and laterally sliding the upper tooling 10 to align the feeding grooves 15 on the front and rear sides of the upper tooling 10 with the needle body mounting grooves 12, at this time the needle bodies are completely exposed, so that the disassembly and feeding of the needle bodies can be realized. By this design, the step of removing the entire upper tooling 10 is omitted, and the efficiency of feeding and discharging is improved.

[0033] Embodiment 4: On the basis of the above embodiment, as Figure 5 shown, a lateral positioning rod 16 for positioning the tooling in the X direction is connected to the right side of the upper end surface of the processing table 8. By providing the lateral positioning rod 16, the tooling can be quickly positioned in the X direction during installation. Longitudinal positioning rods 17 are fixedly connected to the front and rear positions of the upper end surface of the processing table 8. The distance between the longitudinal positioning rods 17 is the same as the width of the lower tooling 9 and the upper tooling 10. The height of the longitudinal positioning rods 17 is aligned with the lowest point of the needle body mounting grooves 12. By providing two sets of longitudinal positioning rods 17, the tooling can be quickly positioned in the Y direction, and the longitudinal positioning rods 17 can give an upward supporting force to the needle body opening position, reducing the vibration and deformation generated by the needle body during the processing, thereby improving the stability and accuracy of the processing.
