Abstract
Description
Technical Field
[0001] This utility model relates to the field of boring and milling of steel products, and in particular to a steel product boring and milling fixture with a positioning mechanism. Background Technology
[0002] Boring and milling of steel products is a composite machining method that combines boring and milling processes. It is mainly used for high-precision forming and hole machining of steel parts. Multiple fixtures are typically used in the boring and milling process and can be switched to allow for simultaneous disassembly and assembly of the steel product during machining.
[0003] Because vibrations are generated during boring and milling, these vibrations can cause the connections between various components of the steel product fixture to loosen. This results in a slight error between the fixture's stopping position after switching and the required position. Positioning errors can cause workpiece displacement, or even cause the workpiece to jam or deform and fail during machining. Utility Model Content
[0004] This utility model discloses a steel product boring and milling fixture with a positioning mechanism, which aims to solve the technical problem that the slight error between the fixture's stopping position after switching and the required position may cause the workpiece to shift, or even cause the workpiece to jam or deform and fail during the processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A steel product boring and milling fixture with a positioning mechanism includes a main support base, a positioning mechanism, an image recognition mechanism, an auxiliary pressing mechanism, a second motor fixedly connected to the inner wall of the main support base, a main support shaft fixedly connected to the output end of the second motor, a plurality of support frames 1 fixedly connected at equal intervals to the outer circumference of the main support shaft, a support plate fixedly connected to the outer end of each support frame 1, and a clamping mechanism fixedly connected to the outer wall of the top of each support plate.
[0007] The positioning mechanism includes a support housing, a boss fixedly connected to the outer wall of the top of the support housing, a rubber pad fixedly attached to the inner wall of the top of the boss, two limiting slots symmetrically arranged through the inner walls of the top of the boss and the support plate, a gas spring fixedly connected to the outer wall of the bottom of the boss, a connecting frame fixedly connected to the outer wall of the bottom of the gas spring, two limiting vertical rods fixedly connected to both ends of the connecting frame, and wedge blocks fixedly connected to the top of each limiting vertical rod.
[0008] The bottom inner wall of the connecting frame is provided with multiple limiting holes, and the bottom outer wall of the boss is fixedly connected with multiple limiting rods, which are respectively movably inserted into the multiple limiting holes.
[0009] The top inner wall of the boss is provided with a mounting groove, and the rubber pad is fixedly attached to the bottom inner wall of the mounting groove.
[0010] With the positioning mechanism in place, when the support plate moves to the top of the positioning mechanism, the pneumatic rod retracts, causing the connecting frame to lift as a whole. The wedge blocks on both sides move upward along the limiting slots on both sides until the outer periphery of the limiting vertical rod completely abuts against the inner wall of the limiting slot. During the entire upward movement, the boss and the limiting slot on the support plate can gradually be completely aligned, thereby ensuring the accuracy of the clamping position of the clamping mechanism. This avoids workpiece displacement caused by clamping position errors, or even workpiece jamming or deformation failure during processing.
[0011] In a preferred embodiment, the auxiliary pressing mechanism includes a sliding groove, an extension groove and a through groove disposed on the inner wall of each wedge block, an electric telescopic rod fixedly connected to the inner wall of the bottom end of the limiting vertical rod, and a sliding plate fixedly connected to the output end of the electric telescopic rod.
[0012] The slide groove, extension groove, and through groove are fixedly connected. A slider is movably connected in the slide groove, and an extension edge is movably connected in the extension groove, with the extension edge fixedly connected to both sides of the slider.
[0013] A hinge seat is fixedly connected to the bottom outer wall of the slider, and the hinge seat passes through the through groove. A connecting rod is hinged to the hinge seat.
[0014] The bottom end of the connecting rod is hinged to a second hinge seat, which is fixedly connected to the top outer wall of the slide plate. The outer periphery of the slide plate is movably attached to the inner wall of the limiting vertical rod.
[0015] With an auxiliary pressing mechanism, the sliding block is pulled by an electric telescopic rod to extend the wedge block and fit against the top outer wall of the support plate. Then, the support plate is pressed against the rubber pad by a short-distance return movement of the air rod until the bottom of the support plate contacts the top of the boss. This ensures the connection between the rubber pad and the bottom of the support plate, further ensuring the shock absorption effect of the rubber pad on the support plate.
[0016] In a preferred embodiment, the image recognition mechanism includes a bearing housing, a support frame movably connected to the bearing housing, and an image processor;
[0017] Support shaft 1 is fixedly connected to the outer walls of the opposite sides of the support frame 2, and support shaft 1 is rotatably connected to the bearing seat. One end of support shaft 1 is fixedly connected to motor 1.
[0018] The image processor is fixedly embedded in the inner wall of the second support frame, and cameras are fixedly connected to both sides of the image processor. Each set of clamping mechanisms includes two clamping plates, and the second support frame is located between the two clamping plates of each set of clamping mechanisms.
[0019] By incorporating an image recognition mechanism, a motor drives a support frame to move between two clamping plates. The camera observes and processes the images to determine if there is wear on the clamping surfaces, thus ensuring timely replacement of the clamping plates.
[0020] As described above, a steel product boring and milling fixture with a positioning mechanism includes a main support base, a positioning mechanism, an image recognition mechanism, an auxiliary pressing mechanism, a motor II fixedly connected to the inner wall of the main support base, a main support shaft fixedly connected to the output end of the motor II, multiple support frames I fixedly connected at equal intervals to the outer circumferential wall of the main support shaft, a support plate fixedly connected to the outer end of each support frame I, and a clamping mechanism fixedly connected to the outer wall of the top of each support plate; the positioning mechanism includes a support housing, a boss fixedly connected to the outer wall of the top of the support housing, a rubber pad fixedly attached to the inner wall of the top of the boss, two limiting slots symmetrically arranged through the inner walls of the boss and the top of the support plate, a gas rod fixedly connected to the outer wall of the bottom end of the boss, a connecting frame fixedly connected to the outer wall of the bottom end of the gas rod, two limiting vertical rods fixedly connected to both ends of the connecting frame, and wedge blocks fixedly connected to the top of each limiting vertical rod. The steel product boring and milling fixture with a positioning mechanism provided by this utility model has the technical effect of ensuring the accuracy of the clamping position of the clamping mechanism and avoiding workpiece displacement caused by the error of the clamping position.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] The steel product boring and milling fixture with a positioning mechanism disclosed in this utility model is mainly used in the scenario of boring and milling steel products.
[0028] Reference Figure 1 and Figure 2 A steel product boring and milling fixture with a positioning mechanism includes a main support base 6, a positioning mechanism 1, an image recognition mechanism 4, an auxiliary pressing mechanism 8, a motor 2 fixedly connected to the inner wall of the main support base 6, a main support shaft 5 fixedly connected to the output end of the motor 2, multiple support frames 7 equidistantly fixedly connected to the outer circumferential wall of the main support shaft 5, a support plate 2 fixedly connected to the outer end of each support frame 7, and a clamping mechanism 3 fixedly connected to the top outer wall of each support plate 2.
[0029] Positioning mechanism 1 includes a support housing 106, a boss 104 fixedly connected to the outer wall of the top of the support housing 106, a rubber pad 101 fixedly attached to the inner wall of the top of the boss 104, two limiting slots 103 symmetrically arranged through the inner walls of the top of the boss 104 and the support plate 2, a gas spring 109 fixedly connected to the outer wall of the bottom of the boss 104, a connecting frame 110 fixedly connected to the outer wall of the bottom of the gas spring 109, two limiting vertical rods 111 fixedly connected to both ends of the connecting frame 110, and wedge blocks 105 fixedly connected to the top of each limiting vertical rod 111. By providing multiple support plates 2 and switching positions via a motor 2, it can be used in the boring and milling of steel products. During the process, the disassembly and installation of steel products at another workstation are completed, improving work efficiency. At the same time, when the support plate 2 moves to the top of the positioning mechanism 1, the air rod 109 retracts, shortening the overall length of the air rod 109, which drives the connecting frame 110 to lift up as a whole. The wedge blocks 105 on both sides move up along the limiting grooves 103 on both sides until the outer periphery of the limiting vertical rod 111 completely abuts against the inner wall of the limiting groove 103. During the entire upward movement, the boss 104 and the limiting groove 103 on the support plate 2 can be gradually driven to completely overlap, thereby ensuring the accuracy of the clamping position of the clamping mechanism 3, thus avoiding workpiece displacement caused by clamping position errors, or even workpiece jamming or deformation failure during processing.
[0030] Reference Figure 2 In a preferred embodiment, the bottom inner wall of the connecting frame 110 is provided with a plurality of limiting holes 108, and the bottom outer wall of the boss 104 is fixedly connected with a plurality of limiting rods 107, which are respectively movably inserted into the plurality of limiting holes 108.
[0031] Reference Figure 2 In a preferred embodiment, the top inner wall of the boss 104 is provided with a mounting groove 102, and the rubber pad 101 is fixedly attached to the bottom inner wall of the mounting groove 102.
[0032] Reference Figure 3 In a preferred embodiment, the auxiliary pressing mechanism 8 includes a sliding groove 802, an extension groove 801 and a through groove 803 disposed on the inner wall of each wedge block 105, an electric telescopic rod 810 fixedly connected to the inner wall of the bottom end of the limiting vertical rod 111, and a sliding plate 808 fixedly connected to the output end of the electric telescopic rod 810.
[0033] Reference Figure 3 In a preferred embodiment, the slide groove 802, the extension groove 801 and the through groove 803 are fixedly connected. A slider 804 is movably connected in the slide groove 802, and an extension edge 805 is movably connected in the extension groove 801, with the extension edge 805 fixedly connected to both sides of the slider 804.
[0034] Reference Figure 3In a preferred embodiment, a hinge seat 806 is fixedly connected to the bottom outer wall of the slider 804, and the hinge seat 806 passes through the through groove 803, and the hinge seat 806 is hinged to the connecting rod 807.
[0035] Reference Figure 3 In a preferred embodiment, the bottom end of the connecting rod 807 is hinged to a second hinge seat 809, and the second hinge seat 809 is fixedly connected to the top outer wall of the slide plate 808. The outer periphery of the slide plate 808 is movably attached to the inner wall of the limiting vertical rod 111. When the wedge block 105 passes through the limiting through groove 103, the slide plate 808 can be pulled down by the electric telescopic rod 810. By pulling the connecting rod 807, the slider 804 is slid to the other end of the slide groove 802. At this time, part of the slider 804 extends out of the wedge block 105, and the bottom end of the extended part is just attached to the top outer wall of the support plate 2. Then, by moving the air rod 109 back a short distance, the support plate 2 can press the rubber pad 101 until the bottom of the support plate 2 contacts the top of the boss 104, thereby ensuring the connection between the rubber pad 101 and the bottom of the support plate 2, and further ensuring the shock absorption effect of the rubber pad 101 on the support plate 2.
[0036] Reference Figure 4 In a preferred embodiment, the image recognition mechanism 4 includes a bearing housing 406, a support frame 403 movably connected to the bearing housing 406, and an image processor 402.
[0037] Reference Figure 4 In a preferred embodiment, the outer walls of the two opposing sides of the support frame 403 are respectively fixedly connected to the support shaft 405, and the support shaft 405 is rotatably connected to the bearing seat 406. One end of the support shaft 405 is fixedly connected to the motor 404.
[0038] Reference Figure 4 In a preferred embodiment, the image processor 402 is fixedly embedded in the inner wall of the second support frame 403, and cameras 401 are fixedly connected to both sides of the image processor 402. Each clamping mechanism 3 includes two clamping plates, and the second support frame 403 is located between the two clamping plates of each clamping mechanism 3. Since the contact surface of the clamping plates may be worn after the clamping mechanism 3 clamps the steel product for a long time, affecting the clamping position of the steel product, the image recognition mechanism 4 can be set to move the second support frame 403 between the two clamping plates by the motor 404 before the corresponding clamping mechanism 3 reaches the boring and milling station. The camera 401 observes and processes the image to determine whether there is wear on the clamping surface, thereby ensuring timely replacement of the clamping plates.
[0039] Working principle: By setting multiple support plates 2 and driving multiple support plates 2 to switch positions through motor 2, the disassembly and installation of steel products at another station can be completed during the boring and milling of steel products, improving work efficiency. At the same time, when the support plate 2 moves to the top of the positioning mechanism 1, the air rod 109 retracts, shortening the overall length of the air rod 109, driving the connecting frame 110 to lift up as a whole. The wedge blocks 105 on both sides move up along the limiting through grooves 103 on both sides until the outer periphery of the limiting vertical rod 111 completely abuts against the inner wall of the limiting through groove 103. During the entire upward movement, the boss 104 and the limiting through groove 103 on the support plate 2 can be gradually driven to completely overlap, thereby ensuring the accuracy of the clamping position of the clamping mechanism 3, thus avoiding workpiece displacement caused by clamping position errors, or even workpiece jamming or deformation failure during processing.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
