Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a drilling tool for the production of hydraulic pipe fittings. Background Technology

[0002] Hydraulic fittings have wide applications in numerous fields, such as construction machinery, aerospace, automotive manufacturing, and shipbuilding. In these fields, hydraulic systems rely on hydraulic fittings to transmit hydraulic oil to achieve various mechanical actions and energy transfer. Different application scenarios have varying requirements for the specifications, dimensions, and precision of hydraulic fittings, and the location, size, and number of holes drilled on the fittings also vary. This necessitates efficient and precise drilling fixtures to meet production demands.

[0003] In a Chinese patent with publication number CN216126862U entitled "A Drilling Device for Pipe Fitting Processing," a design incorporating support plates and bolts avoids the problem of long pipes tilting or shifting during placement without side support, which would affect subsequent fixing and drilling operations. Existing devices often fail to support the pipes. This design allows the pipes to be supported on both sides by the support plates, making them more stable and less prone to tilting. Furthermore, the support height of the support plates can be adjusted by rotating the bolts, making the device more flexible and adaptable to pipes of different specifications. This increases the device's flexibility and convenience.

[0004] However, this device still has shortcomings. When in use, the equipment can only support the pipe fittings but does not fix them. This may cause displacement during the drilling process. The movement of the pipe fittings may cause the drilling position to change, which will not only affect the normal use of the pipe fittings after drilling, but may even cause the pipe fittings to be scrapped due to the change in drilling position, making it inconvenient for people to use. In addition, the installation position of the drilling machine is relatively fixed, which makes it impossible to drill holes at different positions of the pipe fittings, which limits the drilling process and reduces drilling efficiency. In order to solve the above problems, the inventor proposes a drilling tool for hydraulic pipe fitting production. Utility Model Content

[0005] To address the problems of only being able to support pipe fittings without fixing them, which can easily lead to changes in the drilling position, and the relatively fixed installation position of the drilling machine making it impossible to drill holes at various positions on the pipe fittings, thus limiting the drilling process; the purpose of this utility model is to provide a drilling fixture for the production of hydraulic pipe fittings.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a drilling fixture for hydraulic pipe fitting production, including a processing table, with support frames symmetrically slidably inserted at the center of both ends of the processing table, and a limit plate detachably connected to the top of the support frame on the side away from the processing table, with the two limit plates symmetrically distributed, a pipe bracket fixedly connected to the top of the support frame near the limit plate, an mounting frame fixedly connected to the back end of the processing table, a square frame fixedly connected to the front end of the mounting frame, a sliding plate slidably connected between the side walls of the square frame, an mounting plate fixedly connected to the center of the bottom end of the sliding plate, and the mounting plate and the pipe bracket being at the same level, a square box provided below the mounting plate, and a drill bit rotatably connected to the center of the bottom end of the square box.

[0007] Preferably, a motor is fixedly connected to the center of the bottom of the square box, the output end of the motor passes through the square box and is fixedly connected to the drill bit, and a limiting shaft is symmetrically slidably inserted inside the mounting plate near the sliding plate, and the top of the square box is fixedly connected to the limiting shaft.

[0008] Preferably, an electric telescopic rod is fixedly connected to the top of the mounting plate near the sliding plate, and the electric telescopic rod is located at the center of the two limiting shafts. The output end of the electric telescopic rod passes through the mounting plate and is fixedly connected to the square box.

[0009] Preferably, a drive slide is fixedly connected to the top of the square frame and near the center of one side. The top of the drive slide is provided with a U-shaped plate, and the U-shaped plate is fixedly connected to the sliding plate. A double-ended screw is rotatably connected between the side walls of the processing table near the center, and both support frames are threadedly rotatably connected to the double-ended screw.

[0010] Preferably, a rotating handle is rotatably connected to the side end of the processing table near the center, and the side end of the rotating handle passes through the processing table and is fixedly connected to the double-headed screw. A front cover is detachably connected to the center of the front end of the processing table.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, by rotating the double-headed screw and with the cooperation between the pipe bracket, the support frame, and the limiting plate, the positioning of the hydraulic pipe is achieved, thereby solving the problem that the pipe can only be supported but not fixed, which can easily lead to changes in the drilling position.

[0013] 2. In this utility model, by activating the drive slide, and with the cooperation between the sliding plate, the square frame, the drill bit, and the electric telescopic rod, drilling can be completed at different positions of the pipe fitting. This solves the problem that the installation position of the drilling machine is relatively fixed, making it impossible to drill at various positions of the pipe fitting, and thus limiting the drilling process.

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.

[0021] Example: Figure 1-4As shown, this utility model provides a technical solution: a drilling fixture for hydraulic pipe fitting production, including a processing table 1. Support frames 31 are symmetrically slidably inserted at the center of both ends of the processing table 1. A limiting plate 32 is detachably connected to the top of the support frame 31 on the side furthest from the processing table 1, and the two limiting plates 32 are symmetrically distributed. A pipe support 33 is fixedly connected to the top of the support frame 31 near the limiting plate 32. By setting the slidably inserted support frame 31 and the detachable limiting plate 32, it can flexibly adapt to hydraulic pipe fittings of different lengths. The pipe support 33 is used to stably support the pipe fittings, facilitating subsequent drilling operations. A mounting frame 2 is fixedly connected to the back end of the processing table 1, and the front end of the mounting frame 2 is fixedly connected to... A square frame 21 is provided, and a sliding plate 22 is slidably connected between the side walls of the square frame 21. A mounting plate 24 is fixedly connected to the center of the bottom end of the sliding plate 22, and the mounting plate 24 is at the same level as the pipe bracket 33. A square box 26 is provided below the mounting plate 24. The sliding plate 22 can slide within the square frame 21, thereby driving the mounting plate 24 and the drilling assembly below it to move, so as to realize drilling processing at different positions of the pipe. A drill bit 29 is rotatably connected to the center of the bottom end of the square box 26. The electrical components in this application and their compatible power supply are electrically connected through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection means are known in the art.

[0022] A motor 27 is fixedly connected to the center of the bottom of the box 26. The output end of the motor 27 passes through the box 26 and is fixedly connected to the drill bit 29.

[0023] By adopting the above technical solution, the motor 27 provides power to the drill bit 29, ensuring efficient and stable drilling operations. The motor 27 is a variable frequency speed control motor 27, which can adjust the speed according to the pipes of different materials.

[0024] A limiting shaft 25 is symmetrically slidably inserted inside the mounting plate 24 near the sliding plate 22, and the top of the square box 26 is fixedly connected to the limiting shaft 25.

[0025] By adopting the above technical solution, the limiting shaft 25 slides within the mounting plate 24, which limits and guides the up and down movement of the square box 26 and the drill bit 29, ensuring the stability of the drilling process.

[0026] An electric telescopic rod 28 is fixedly connected to the top of the mounting plate 24 near the sliding plate 22, and the electric telescopic rod 28 is located at the center of the two limiting shafts 25. The output end of the electric telescopic rod 28 passes through the mounting plate 24 and is fixedly connected to the square box 26.

[0027] By adopting the above technical solution, the electric telescopic rod 28 can accurately control the lifting height of the drill bit 29, adapting to the drilling needs of hydraulic pipe fittings with different diameters.

[0028] A drive slide 23 is fixedly connected to the top of the square frame 21 and near the center of one side. The top of the drive slide 23 is provided with a U-shaped plate, and the U-shaped plate is fixedly connected to the sliding plate 22.

[0029] By adopting the above technical solution, the drive slide 23 can drive the sliding plate 22 and the entire drilling assembly to move laterally within the square frame 21, thereby realizing drilling at different positions of the pipe and improving the flexibility of processing.

[0030] A double-ended screw 3 is rotatably connected between the side walls of the processing table 1 near the center, and both support frames 31 are threadedly rotatably connected to the double-ended screw 3.

[0031] By adopting the above technical solution, rotating the double-headed screw 3 can make the two support frames 31 move synchronously in opposite directions, which facilitates the adjustment of the distance between the pipe brackets 33 to accommodate pipes of different lengths.

[0032] A rotating handle is rotatably connected to the side end of the processing table 1 near the center, and the side end of the rotating handle passes through the processing table 1 and is fixedly connected to the double-headed screw 3.

[0033] By adopting the above technical solution, the double-ended screw 3 can be operated by rotating the handle, which is simple and convenient, thereby improving the ease of use of the double-ended screw 3.

[0034] The front cover 34 is detachably connected to the center of the front end of the processing table 1.

[0035] By adopting the above technical solution, the front cover 34 makes it easy to open the inside of the processing table 1, which facilitates the maintenance, cleaning and repair of the internal double-headed screw 3.

[0036] Working principle: First, place the hydraulic fitting to be processed above the center of the two pipe supports 33. Then, rotate the handle to drive the double-headed screw 3 to rotate, so that the two support frames 31 slide towards each other under the action of the processing table 1. Adjust the position between the two limit plates 32 to achieve the positioning of the hydraulic fitting. A front cover 34 is set at the front end of the processing table 1 so that the internal structure of the processing table 1 can be inspected, repaired and cleaned, thereby ensuring the normal operation of the equipment.

[0037] When drilling into the pipe fitting, the drive slide 23 is activated, which drives the sliding plate 22 to move laterally within the square frame 21, so that the drill bit 29 moves above the position to be drilled in the pipe fitting. According to the pipe diameter and drilling depth requirements, the electric telescopic rod 28 is activated, which pushes the square box 26 and the drill bit 29 to descend or rise. The limit shaft 25 slides synchronously within the mounting plate 24 to ensure that the drill bit 29 reaches the appropriate drilling depth. The motor 27 is activated, which drives the drill bit 29 to rotate at high speed to perform drilling operations on the pipe fitting. In this way, drilling work can be completed at different positions of the pipe fitting.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
