Description

Technical Field

[0001] This utility model relates to the technical field of hardware processing, specifically to an adjustable tapping fixture for hardware processing. Background Technology

[0002] Metal processing tapping fixtures use specific positioning components, such as positioning pins and positioning blocks, to cooperate with positioning reference surfaces or holes on the workpiece to accurately fix the workpiece in the fixture. This ensures that the part of the workpiece to be tapped maintains coaxiality and perpendicularity with the axis of the tap, thereby guaranteeing the positional accuracy of tapping.

[0003] A search revealed Chinese Patent Publication No. CN219131017U, which discloses an adjustable tapping fixture for metal processing. The fixture includes a main body, a clamping mechanism, and a supporting mechanism. The clamping mechanism is located at the upper end of the main body, and the supporting mechanism is located at the lower end. The main body includes a working platform, a support plate, an electric push rod, a connecting plate, and a connecting plate. The support plate is fixedly installed on the upper end of the working platform, and the electric push rod is fixedly installed on the upper end of the support plate and the connecting plate, respectively. This adjustable tapping fixture for metal processing, through improvements and modifications to the main body, enhances its working capacity. In practical use, it facilitates the use of the adjustable tapping fixture and improves the user experience.

[0004] However, the distance between electric push rod one and electric push rod two is fixed when using the tapping tool. This means that when fixing the position of hardware parts of different sizes, the position between the processing head and the rotating shaft cannot be adjusted according to the length of the hardware parts. At the same time, the position of the hardware parts cannot be easily adjusted during processing, thus reducing the efficiency of the tapping tool. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable tapping fixture for hardware processing. It solves the problem that the distance between the first and second electric push rods is fixed during use, which prevents the adjustment of the position between the processing head and the rotating shaft based on the length of the hardware parts when fixing their positions. Furthermore, it hinders convenient adjustment of the hardware parts' position during processing, thus reducing the efficiency of the tapping fixture.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable tapping fixture for hardware processing, comprising a base and a clamping block. The top surface of the base is provided with an installation groove, and a cylinder is fixedly installed inside the installation groove. A support plate is fixedly installed on the output shaft of the cylinder. Fixed plates are symmetrically fixedly installed on the upper end of the base, and the fixed plates are symmetrically arranged on both sides of the installation groove. A pressing screw is threadedly connected to the inside of the side wall of the fixed plate. A handwheel is fixedly installed at one end of each pressing screw. The clamping block is symmetrically arranged between the two fixed plates, and a connecting column is fixedly connected to the other end of each pressing screw, and is rotatably connected to the inside of the side wall of the clamping block.

[0007] Preferably, a limiting rod is provided between the two fixed plates, and both clamping blocks are slidably sleeved on the wall of the limiting rod. Limiting blocks are fixedly installed at both ends of the limiting rod, and the limiting blocks are respectively located outside the clamping blocks, thereby preventing the limiting rod from falling out of the clamping blocks.

[0008] Preferably, the top surface of the base is symmetrically provided with sliding grooves. An adjusting screw is rotatably connected to each of the two sliding grooves, and a sliding rod is fixedly connected to each of the two grooves. A U-shaped frame is provided at the upper end of the base. The lower ends of the U-shaped frame are slidably connected to the interior of the sliding grooves and are respectively threaded onto the wall of the adjusting screw and slidably connected to the wall of the sliding rod. A reciprocating motor is fixedly installed on the front side wall of the base. The output shaft of the reciprocating motor is fixedly connected to the front end of the adjusting screw through the interior of the side wall of the base. An electric push rod is fixedly installed at the upper end of the U-shaped frame. A drive device is fixedly installed on the output shaft of the electric push rod, and a processing head is fixedly installed at the lower end of the drive device, thereby facilitating the processing of hardware parts in different positions.

[0009] Preferably, the length of the limiting rod is less than the distance between the two fixed plates and greater than the distance between the two clamping blocks, so that the clamping blocks can be easily adjusted on the limiting rod.

[0010] Preferably, the diameter of the limiting block is larger than the diameter of the limiting rod, thereby limiting the position of the clamping block.

[0011] Preferably, the width of the support arms on both sides below the U-shaped frame is matched with the width of the slide groove, thereby making the movement of the U-shaped frame more stable.

[0012] This utility model provides an adjustable tapping fixture for hardware processing. It has the following beneficial effects:

[0013] This adjustable tapping fixture for hardware processing allows for convenient movement of the processing head based on the position of the clamped hardware part through the cooperation between the U-shaped frame, electric push rod, and clamping block, facilitating the processing of the hardware.

[0014] This adjustable tapping fixture for hardware processing allows the clamping block to rotate during use. A support plate then presses the adjusted clamping block upwards, stabilizing its position and making it easier to adjust the position of the hardware during processing. Attached Figure Description
