Description

Technical Field

[0001] This application relates to the technical field of machining and fixing, and in particular to a fixing mold for drilling machine parts. Background Technology

[0002] In the field of machining, drilling is a common and important processing method, widely used in the manufacture of various parts. With the continuous development of industry, the requirements for the precision and efficiency of drilling are becoming increasingly stringent. The fixation of drilled parts is a crucial step in ensuring machining quality. A good fixation method can effectively improve machining accuracy, reduce scrap rates, and is of great significance for improving the efficiency of the entire production process and reducing costs. In industries with extremely high precision requirements, such as aerospace and automotive manufacturing, the fixation effect of drilled parts directly affects the performance and quality of the products.

[0003] In traditional drilling machine machining, the following methods are commonly used to fix the tubular parts to be machined. One method is to use a simple clamp to directly fix the tube to the worktable using bolts or other connectors. This method is relatively simple to operate, but for machining tasks that require multiple adjustments to position or angle, the clamping efficiency is low and the positioning accuracy is difficult to guarantee. Another method is to use a combination of positioning blocks and pressure plates. The positioning blocks are placed in the appropriate positions, and then the pressure plates are used to press the tube to be machined onto the worktable. This method can adapt to machining tasks that require multiple adjustments to position or angle to a certain extent, but uneven force applied by the pressure plates can easily cause deformation of the tube, affecting machining accuracy. Moreover, the disassembly and assembly process is cumbersome and time-consuming. Utility Model Content

[0004] To overcome the above-mentioned technical problems, this application provides a fixing mold for drilling machine parts.

[0005] The technical solution for a drilling machine machining part fixing mold provided in this application is as follows: A drilling machine machining part fixing mold includes a base, on which a pipe rack for supporting the pipe to be processed is horizontally mounted. One end of the base is provided with a fixed limiting plate, which is fixedly connected to the base. The other end of the base is provided with a movable limiting plate, which is slidably connected to the base and can move closer to or further away from the fixed limiting plate. The side of the pipe rack away from the base is provided with a pipe clamp for fixing the pipe to be processed, which is slidably connected to the base and can move closer to or further away from the base.

[0006] By adopting the above technical solution, the pipe rack can support the pipe to be processed, the fixed limit plate and the moving limit plate can cooperate to limit the two ends of the pipe to be processed, and the pipe clamp can fix the pipe to be processed on the pipe rack, which facilitates the drilling of the pipe to be processed.

[0007] Optionally, the top of the tube rack is provided with a rack groove, the cross-sectional profile of the rack groove is semi-circular and matches the tube to be processed, the rack groove is provided with multiple keyways, the keyways are set at an angle to the vertical direction, the plane of the keyways is perpendicular to the extension direction of the tube rack, a positioning key is slidably connected in the keyway, the end of the positioning key near the bottom of the keyway is provided with a first elastic element, and the shaft diameter of the positioning key matches the diameter of the opening of the tube to be processed.

[0008] By adopting the above technical solution, the semi-circular support groove that matches the tube to be processed can better support the tube to be processed. During the first processing, the tube to be processed is fixed in the support groove under the action of the tube clamp, and the positioning key is pressed into the keyway. When the hole is opened and rotated to a preset angle for processing again, the tilted keyway and the positioning key therein, together with the first elastic element, can make the positioning key insert into the already processed hole for positioning when the tube to be processed is placed, thereby improving the accuracy and stability of the positioning of the tube to be processed.

[0009] Optionally, the moving limit plate is provided with a horizontal guide rod on the side near the base, and the base is provided with a horizontal guide hole that cooperates with the horizontal guide rod.

[0010] By adopting the above technical solution, the horizontal guide rod and the horizontal guide hole cooperate to make the moving limit plate stably approach or move away from the fixed limit plate in a specific direction, ensuring the stability and accuracy of the sliding of the moving limit plate, thereby better limiting the tube to be processed.

[0011] Optionally, it also includes a screw, which is rotatably connected to the base around its own axis. The screw is located on the side of the base away from the tube frame and is arranged parallel to the extension direction of the tube frame. The movable limiting plate is provided with a screw hole that cooperates with the screw.

[0012] By adopting the above technical solution, the screw is rotatably connected to the base and set parallel to the extension direction of the tube rack. The moving limit plate is provided with a screw hole that cooperates with the screw. By rotating the screw, the moving limit plate can be driven to move closer to or away from the fixed limit plate, thereby realizing the clamping and loosening of the tube to be processed. The operation is convenient and can effectively fix the tube to be processed.

[0013] Optionally, the number of pipe clamps is two, one of which is located between the pipe rack and the fixed limiting plate, and the other is located between the pipe rack and the movable limiting plate. The bottom of the pipe clamp is provided with a clamping groove, and the cross-sectional profile of the clamping groove is semi-circular and matches the pipe to be processed.

[0014] By adopting the above technical solution, pipe clamps are set at both ends of the pipe rack, and the semi-circular clamping groove at the bottom of the pipe clamp matches the pipe to be processed, which can better fix the pipe to be processed from both ends and improve the stability of the pipe to be processed during the processing.

[0015] Optionally, the pipe clamp is provided with a vertical guide hole, and the base is provided with a vertical guide rod that cooperates with the vertical guide hole. A second elastic element is sleeved on the vertical guide rod. One end of the second elastic element is used to abut against the pipe clamp, and the other end is used to abut against the base.

[0016] By adopting the above technical solution, the pipe clamp slides by means of the cooperation between the vertical guide hole and the vertical guide rod on the base. The second elastic element sleeved on the vertical guide rod abuts the pipe clamp at one end and abuts the base at the other end, which can make the pipe clamp reset after movement, ensuring that it returns to the initial position after use, making it easy to take out the processed pipe and put in the next pipe to be processed.

[0017] Optionally, the pipe clamp is provided with traction ropes on both sides, and the screw is provided with rope hooks for fixing the traction ropes. The end of the traction rope away from the pipe clamp is connected to the rope hook.

[0018] By adopting the above technical solution, when rotating the screw, the traction rope can be used to drive the pipe clamp to slide closer to or away from the base, thereby fixing and loosening the pipe clamp on the workpiece of the drilling machine, making the operation more convenient and efficient.

[0019] Optionally, the base is provided with pulleys on both sides for cooperating with the traction rope.

[0020] By adopting the above technical solution, the pulley can change the direction of the traction rope, so that the traction rope can smoothly connect the rope hook on the pipe clamp and the screw, reduce the friction between the traction rope and the base, and improve the traction efficiency and the overall stability of the mold.

[0021] Optionally, a handle is provided at one end of the screw.

[0022] By adopting the above technical solution, a handle is set at one end of the screw, which makes it convenient for the operator to rotate the screw and adjust the position of the moving limit plate more conveniently, so as to realize the clamping or loosening operation of the tube to be processed, thus improving the convenience of operation.

[0023] Optionally, a first rubber pad is provided at the clamping groove, and a second rubber pad is provided on the side of the moving limiting plate near the fixed limiting plate.

[0024] By adopting the above technical solution, the first rubber pad and the second rubber pad can increase the friction with the tube to be processed, prevent the tube to be processed from sliding during the processing, and at the same time play a buffering role.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The pipe to be processed is supported by a pipe rack, and the fixed limit plate and the moving limit plate limit its axial movement. The pipe clamp fixes it, which improves the stability of the pipe to be processed, ensures the accuracy of the drilling machine, and reduces the scrap rate. 2. The screw drives the limit plate to move, and in conjunction with the linkage structure of the traction rope and the pipe clamp, it can quickly clamp and release, significantly improving clamping efficiency; 3. By setting rubber pads and elastic elements, the reliability of clamping is enhanced, mechanical wear between components is reduced, and the service life of the device is extended.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses a fixing mold for drilling machine parts.

[0031] like Figure 1 and Figure 2 As shown, the fixed mold for drilling machine parts includes a base 1, a pipe rack 2, a fixed limiting plate 3, a movable limiting plate 4, and a pipe clamp 5. The pipe rack 2 is horizontally installed on the base 1 to support the pipe to be processed. The fixed limiting plate 3 is fixed at one end of the base 1. The movable limiting plate 4 can slide close to or away from the fixed limiting plate 3 and is slidably connected to the base 1. The pipe clamp 5 is located on the side of the pipe rack 2 away from the base 1 and can slide close to or away from the base 1 and is slidably connected to the base 1.

[0032] Specifically, the pipe rack 2 is horizontally mounted on the base 1, serving as a support and fulcrum. Its material can be metal, such as stainless steel, which offers good strength and stability; or it can be high-strength plastic, which is lightweight and cost-effective. A rack groove 201 is located at the top of the pipe rack 2, with a semi-circular cross-section that matches the pipe to be processed, allowing for better fit and stable support. Multiple keyways are provided at the rack groove 201, angled to the vertical direction, and the plane of the keyways is perpendicular to the extension direction of the pipe rack 2. A positioning key 6 is slidably connected within the keyway. A first elastic element, such as a spring, is located at the end of the positioning key 6 near the bottom of the keyway, providing elastic support for the positioning key 6. The shaft diameter of the positioning key 6 matches the diameter of the opening in the pipe to be processed. During the initial processing, the pipe to be processed is fixed in the rack groove 201 by the pipe clamp 5, and the positioning key 6 is pressed into the keyway. After the opening is completed, when processing is performed again by rotating a preset angle, the positioning key 6 can be inserted into the opening of the pipe to be processed, serving a positioning and fixing function.

[0033] like Figure 1 and Figure 2 As shown, the movable limiting plate 4 can be made of metal, such as aluminum alloy, which has good strength and light weight. A horizontal guide rod 401 is provided on the side of the movable limiting plate 4 near the base 1. The base 1 has a horizontal guide hole that mates with the horizontal guide rod 401. The horizontal guide rod 401 can be a round rod or a square rod, as long as it can slide smoothly in the horizontal guide hole. Through the cooperation of the horizontal guide rod 401 and the horizontal guide hole, the movable limiting plate 4 can slide along the base 1, realizing movement towards or away from the fixed limiting plate 3.

[0034] To control the movable limit plate 4, the drilling machine machining part fixing mold also includes a screw 7. The screw 7 is rotatably connected to the base 1 around its own axis and is located on the side of the base 1 away from the tube frame 2, parallel to the extension direction of the tube frame 2. The screw 7 can be made of metal, such as carbon steel, which has good strength and wear resistance. For rotatable connection with the base 1, a mounting seat 102 can be provided on the side of the base 1 away from the tube frame 2. The mounting seat 102 contains a bearing, and the screw 7 can have a journal that mates with the bearing, enabling the screw 7 to rotate on the mounting seat 102. The movable limit plate 4 has a threaded hole that mates with the screw 7. When the screw 7 is rotated, due to the limiting effect of the horizontal guide rod 401 and the horizontal guide hole, the movable limit plate 4 cannot rotate with the screw 7, but can only move along the axial direction of the screw 7, thus achieving adjustment of the movable limit plate 4. One end of the screw 7 can be connected to a handle 703 for manual rotation, or it can be adapted to a power tool for automated adjustment.

[0035] like Figure 1 and Figure 2As shown, there are two pipe clamps 5. One of the pipe clamps 5 is located between the pipe rack 2 and the fixed limiting plate 3, and the other is located between the pipe rack 2 and the movable limiting plate 4. The bottom of the pipe clamp 5 is provided with a clamping groove 501. The cross-sectional profile of the clamping groove 501 is semi-circular and matches the pipe to be processed. By setting pipe clamps 5 at both ends of the pipe rack 2, and the semi-circular clamping groove 501 at the bottom of the pipe clamp 5 matches the pipe to be processed, the pipe to be processed can be better fixed from both ends, improving the stability of the pipe to be processed during the processing.

[0036] Specifically, the pipe clamp 5 can be made of metal or plastic. The bottom of the pipe clamp 5 has a clamping groove 501, the cross-sectional profile of which is semi-circular and matches the pipe to be processed, allowing for better fit and fixation. A first rubber pad is provided at the clamping groove 501, increasing the friction between the clamping groove 501 and the pipe to be processed while preventing damage to the surface of the pipe. The pipe clamp 5 has a vertical guide hole 502 that penetrates through it. The base 1 has a vertical guide rod 101 that mates with the vertical guide hole 502. A second elastic element 8, such as a spring, is sleeved on the vertical guide rod 101. One end of the second elastic element 8 abuts against the pipe clamp 5, and the other end abuts against the base 1. Through the cooperation of the vertical guide rod 101 and the vertical guide hole 502, the pipe clamp 5 can slide along the vertical guide rod 101, moving closer to or away from the base 1. The pipe clamp 5 has traction ropes 9 on both sides, and the screw 7 has rope hooks 701 for fixing the traction ropes 9. The end of the traction rope 9 away from the pipe clamp 5 is connected to the rope hook 701. In order to protect the rope hook 701, the screw 7 may have a hook groove 702 for accommodating the rope hook 701. The base 1 has pulleys 10 on both sides for cooperating with the traction ropes 9. The pulleys 10 can reduce the friction between the traction rope 9 and the base 1, so that the movement of the traction rope 9 is smoother.

[0037] The coordination of the traction rope 9, the rope hook 701, and the pulley 10 allows the movement of the pipe clamp 5 to be correlated with the movement of the moving limit plate 4. When the moving limit plate 4 approaches the fixed limit plate 3, the traction rope 9 pulls the pipe clamp 5 closer to the base 1, thereby fixing the pipe to be processed. When the moving limit plate 4 moves away from the fixed limit plate 3, the pipe clamp 5 moves away from the base 1 under the action of the second elastic element 8, making it easier to remove the pipe to be processed.

[0038] The implementation principle of a drilling machine machining part fixing mold according to an embodiment of this application is as follows: Through the coordinated work of its various components, the drilling machine machining part fixing mold achieves flexible fixing of pipes of different diameters and lengths to be processed. The support groove 201 and positioning key 6 of the pipe rack 2 can stably support and position the pipe to be processed. The sliding structure of the moving limit plate 4 and the cooperation of the screw 7 can adapt to pipes of different lengths to be processed. The elastic movement of the pipe clamp 5 and the associated structure of the traction rope 9 can effectively fix the pipe to be processed. Compared with traditional fixing methods, this fixing mold is easier to operate, can be quickly adjusted to adapt to pipes of different specifications, greatly improves the accuracy and efficiency of drilling machine machining, reduces production costs, and has strong practicality and innovation.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
