Description
Technical Field
[0001] This utility model relates to the field of metal plate processing technology, specifically to a multi-station tapping fixture and tapping machine for metal plates. Background Technology
[0002] Tapping fixtures are a type of process equipment used to assist, position, and clamp workpieces during the tapping process, ensuring that the tapping operation can be carried out accurately and efficiently. By combining tapping fixtures with tapping machines, the tapping quality can be significantly improved.
[0003] For example, Chinese patent (publication number: CN218168962U) discloses a precision positioning tapping fixture, including a housing. An adjustment component is installed inside the housing, and two vertical plates are positioned above the adjustment component. A frame is fixedly connected to the top of the two vertical plates. A fixing component is installed inside the frame, and the fixing component includes two horizontal bars fixedly connected to the inner wall of the frame. Two locking blocks are slidably connected to the outside of the two horizontal bars. In this utility model, by using the fixing component and pulling the locking blocks on one side of the lever with a handle, the workpiece can be quickly fixed under the action of a spring, facilitating smooth tapping of the workpiece. The operation is more convenient, saving time and effort, and greatly reducing the workload during operation, making it more practical.
[0004] However, the tooling is not efficient enough. Since it can only clamp and position one workpiece at a time and can only process one workpiece at a time, its efficiency is not high in actual use. Therefore, a multi-station tapping tooling and tapping machine for metal plates is proposed to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a multi-station tapping fixture and tapping machine for metal plates, which has the advantage of high clamping efficiency and solves the problem of low efficiency where the fixture can only clamp one workpiece at a time.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station tapping fixture for metal plates, including a housing, two clamping blocks fixed to the top of the housing, stabilizing blocks fixed to the left and right sidewalls of the inner cavity of the housing, an adjusting component movably connected to each stabilizing block and the sidewall of the housing and capable of horizontal adjustment, a stepped groove communicating with the inner cavity of the housing opened at the bottom of the housing, a discharge plate fixed to the inner top wall of the stepped groove, and a protective component for protecting the adjusting component between the two adjusting components;
[0007] Each of the adjustment components includes a threaded rod, a connecting block, and a limiting pin. The threaded rod is movably connected to the inner cavity of the stabilizing block and passes through the stabilizing block and the side wall of the outer shell. Turntables are fixed on opposite sides of the two threaded rods and outside the outer shell. The outer surface of the threaded rod is threadedly connected to the connecting block. The top of the connecting block is fixed to the limiting pin that passes through the top wall of the outer shell. A limiting plate that abuts against the discharge plate is fixed at the bottom of the connecting block.
[0008] By adopting this technical solution, the two clamping blocks can be adjusted to fit metal plates of different sizes, and the two limiting pins can simultaneously limit the positions of two workpieces, thereby processing two workpieces at the same time and effectively improving processing efficiency.
[0009] Furthermore, the top of the outer shell is provided with multiple mounting holes, and the top of each clamping block is fixed with two mounting bolts that penetrate the clamping block and extend into the mounting holes, and each mounting bolt is threadedly connected to the mounting hole.
[0010] By adopting this technical solution, the mounting bolts facilitate the disassembly and installation of the clamping blocks, and the multiple mounting holes enable the two clamping blocks to be easily fixed even after their positions are changed.
[0011] Furthermore, the top of the outer shell is provided with a movable groove that communicates with the inner cavity of the outer shell, and each of the limiting pins passes through the top wall of the outer shell through the movable groove.
[0012] By adopting this technical solution, the limiting pin is used to limit the workpiece, and the moving groove facilitates the movement of the limiting pin.
[0013] Furthermore, the two threaded rods are rotatably connected by bearings, and ribs are fixed to the outer sides of both stabilizing blocks. The side of each rib closest to the outer shell is fixed to the side wall of the inner cavity of the outer shell.
[0014] By adopting this technical solution, the bearing can ensure that the two threaded rods do not interfere with each other when they rotate, thus allowing the two limit pins to move in different directions at the same time to adapt to different workpieces and further improve processing efficiency.
[0015] Furthermore, the protective assembly includes two fixed cylinders, a compression spring, a protective inner cylinder, and a protective outer cylinder. The two fixed cylinders extend into the two connecting blocks and are fixed to the connecting blocks. The opposite sides of the two fixed cylinders are fixed to the compression spring. The protective inner cylinder and the protective outer cylinder are located inside and outside the two compression springs, respectively, and are movably connected to the compression springs. Both the protective inner cylinder and the protective outer cylinder extend into the two connecting blocks and are movably connected to the connecting blocks.
[0016] By adopting this technical solution, the protective component can protect the opposite sides of the two threaded rods from the influence of processing waste, thereby improving overall stability.
[0017] Furthermore, a stabilizing frame is fixed to the outer surface of the protective outer cylinder, and the protective outer cylinder is fixed to the front and rear side walls of the inner cavity of the outer shell through the stabilizing frame.
[0018] By adopting this technical solution, the stabilizing frame can improve the stability of the protective components, enabling the protective components to continuously and effectively protect the adjustment components.
[0019] Furthermore, the opposite sides of the two extension tubes extend into the two stabilizing blocks, and the opposite sides of the two extension tubes extend into the two connecting blocks.
[0020] By adopting this technical solution, the extension tube and the protective components work together to provide comprehensive protection for the adjustment components.
[0021] Furthermore, the discharge plate has two countersunk holes, and countersunk bolts are threaded into both countersunk holes. The discharge plate is fixed to the top wall of the stepped groove by the two countersunk bolts.
[0022] By adopting this technical solution, countersunk bolts and countersunk holes can effectively improve the flatness of the bottom of the housing, thereby effectively improving the machining accuracy.
[0023] Tapping machine, including the aforementioned multi-station tapping fixture for metal plates.
[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0025] This multi-station tapping fixture and tapping machine for metal plates requires users to first adjust the adjustment components and two clamping blocks according to the actual size of the fixture. The fixture is then fixed on the worktable of the tapping machine. By using a multi-output tapping machine in conjunction with this fixture, multiple sets of workpieces can be clamped simultaneously, thereby tapping multiple workpieces at the same time, further improving production efficiency. In addition, the actual adjustment components and clamping blocks work together to effectively improve the adaptability of the tapping fixture to workpieces. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1 to 2 In this embodiment, the multi-station tapping fixture for metal plates includes a housing 1. Two clamping blocks 2 are fixed to the top of the housing 1. The two clamping blocks 2 can be adapted to workpieces of different sizes by changing their positions. Stabilizing blocks 3 are fixed on the left and right side walls of the inner cavity of the housing 1. The stabilizing blocks 3 are used to improve the stability of the adjustment components 4. Each stabilizing block 3 is movably connected to an adjustment component 4 that passes through the stabilizing block 3 and the side wall of the housing 1 and can be adjusted horizontally. A stepped groove communicating with the inner cavity of the housing 1 is opened at the bottom of the housing 1. A discharge plate 5 is fixed to the inner top wall of the stepped groove. After the processing is completed, the tapping fixture can be removed and the discharge plate 5 can be removed to clean the processing waste in the housing 1. A protective component 6 is provided between the two adjustment components 4 to protect the adjustment components 4.
[0032] In addition, the top of the outer shell 1 is provided with multiple mounting holes. Each clamping block 2 has two mounting bolts that pass through the clamping block 2 and extend into the mounting holes. Each mounting bolt is threaded to the mounting hole. The multiple mounting holes can ensure that the two clamping blocks 2 can be stably fixed to the outer shell 1 when the position is adjusted.
[0033] It is known that each adjustment component 4 includes a threaded rod 401, a connecting block 402, and a limiting pin 403. The threaded rod 401 is movably connected to the inner cavity of the stabilizing block 3. The threaded rod 401 passes through the stabilizing block 3 and the side wall of the outer shell 1. A turntable is fixed on the opposite side of the two threaded rods 401 and outside the outer shell 1. The user only needs to rotate the turntable to drive the threaded rod 401 to rotate, thereby causing the limiting pin 403 to be adjusted. The outer surface of the threaded rod 401 is threadedly connected to the connecting block 402. The top of the connecting block 402 is fixed to the limiting pin 403 that passes through the top wall of the outer shell 1. A limiting plate is fixed at the bottom of the connecting block 402 to abut against the discharge plate 5. The limiting plate is used to limit the movement of the connecting block 402 to ensure that the connecting block 402 can move stably.
[0034] It should be further explained that the top of the outer shell 1 is provided with a movable groove that communicates with the inner cavity of the outer shell 1. Each limiting pin 403 passes through the top wall of the outer shell 1 through the movable groove. A scale plate is fixed on the top of the outer shell 1. The scale plate is located on the rear side of the movable groove. When the limiting pin 403 is moved, its position can be determined by comparing it with the scale on the scale plate. The two threaded rods 401 are rotatably connected by a bearing. Ribs are fixed on the outer sides of the two stabilizing blocks 3. The side of each rib closest to the outer shell 1 is fixed to the side wall of the inner cavity of the outer shell 1. The ribs can effectively improve the stability of the stabilizing blocks 3. The opposite sides of the two extension cylinders 7 extend into the two stabilizing blocks 3, and the opposite sides of the two extension cylinders 7 extend into the two connecting blocks 402.
[0035] In this embodiment, when using it, first adjust the positions of the two clamping blocks 2 and the two limiting pins 403 according to the size of the metal plate to ensure that different workpieces can be processed smoothly. Then, place the two metal plates at opposite positions of the two limiting pins 403 to complete the positioning.
[0036] Please refer to it again. Figure 1 and Figure 3 In order to effectively protect the adjustment component 4, the discharge plate 5 in this embodiment has two countersunk holes, and countersunk bolts are threaded into the two countersunk holes. The discharge plate 5 is fixed to the top wall of the stepped groove by the two countersunk bolts. The countersunk holes and countersunk bolts cooperate to effectively ensure the flatness of the bottom of the discharge plate 5, and further improve the processing accuracy.
[0037] In addition, the protection component 6 includes two fixed cylinders 601, a compression spring 602, a protective inner cylinder 603, and a protective outer cylinder 604. The two fixed cylinders 601 extend into the two connecting blocks 402 and are fixed to the connecting blocks 402. The opposite side of the two fixed cylinders 601 is fixed to the compression spring 602. The protective inner cylinder 603 and the protective outer cylinder 604 are located inside and outside the two compression springs 602, respectively, and are movably connected to the compression springs 602. Both the protective inner cylinder 603 and the protective outer cylinder 604 extend into the two connecting blocks 402 and are movably connected to the connecting blocks 402. When the connecting blocks 402 move, they will drive the fixed cylinders 601 to move. By interleaving the fixed cylinders 601, the protective inner cylinder 603, and the protective outer cylinder 604, the intrusion of processing coolant can be effectively prevented, while also blocking processing waste, thus effectively improving the stability of the adjustment component 4.
[0038] It should be further explained that a stabilizing frame is fixed to the outer surface of the protective outer cylinder 604. The protective outer cylinder 604 is fixed to the front and rear side walls of the inner cavity of the outer shell 1 through the stabilizing frame. The stabilizing frame is used to improve the stability of the protective outer cylinder 604 and ensure that the protective outer cylinder 604 will not move.
[0039] In addition, tapping machines include the aforementioned multi-station tapping fixtures for metal plates.
[0040] In this embodiment, the tapping machine is a multi-output shaft tapping machine. By cooperating with the clamping fixture, it can significantly improve the processing efficiency of metal plates. The protection component 6 and the extension cylinder 7 can effectively protect the adjustment component 4 and effectively adjust the service life of the component 4.
[0041] It is understandable that by rotating the two turntables, the two threaded rods 401 can be controlled separately, causing the two limit pins 403 to adjust their positions. This helps the two limit pins 403 to adjust more quickly, thereby effectively improving processing efficiency.
[0042] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0043] The working principle of the above embodiments is as follows:
[0044] Before use, fix the tapping fixture on the tapping machine's worktable. Rotate the threaded rod 401. Due to the action of the limiting plate, the connecting block 402 will move, thereby driving the limiting pin 403 on it to move together. When the limiting pin 403 is moved to the appropriate position, adjust the position of the two clamping blocks 2 to better adapt to different workpieces. After the adjustment is completed, start the tapping machine. The tapping head on the tapping machine can tap multiple workpieces at the same time. The operator only needs to use both hands to place two workpieces at opposite positions of the two limiting pins 403 to complete the positioning and limiting of the workpieces. With the help of the clamping blocks 2, the workpieces are prevented from shaking, thereby effectively improving the tapping efficiency. Furthermore, the two limiting pins 403 can move freely, which can further improve the versatility.
