Description

Technical Field

[0001] This utility model belongs to the technical field of four-way fixtures, and specifically relates to a fixture for processing square four-way fixtures. Background Technology

[0002] In the field of machining, the square four-way valve is a key component for achieving multi-directional connectivity in piping systems, and its machining accuracy directly affects subsequent assembly and performance. During the cutting and drilling processes of the square four-way valve, the fixing effect of the fixture plays a decisive role in the machining quality.

[0003] Traditional square four-way machining fixtures typically employ a fixed clamping structure, which has the following technical drawbacks:

[0004] Poor versatility and limited applicability: The fixed positioning points of the fixed fixture cannot adapt to the processing needs of square four-way tubes of different specifications. When changing workpieces, the fixture needs to be disassembled and reassembled, resulting in low production efficiency. Utility Model Content

[0005] This utility model addresses the problems of the prior art by providing a jig for machining square four-way connectors. The specific technical solution is as follows:

[0006] A jig for machining a square four-way valve includes a machining table for supporting the square four-way valve and four fixing components that are slidably mounted on the machining table. Each fixing component includes a vertically mounted screw, a pressing block slidably sleeved on the screw, and a pressing sleeve screwed onto the screw. The pressing sleeve is positioned above the pressing block. In the installed state, the pressing block presses against the square four-way valve, and the pressing sleeve presses against the upper surface of the pressing block.

[0007] As a further technical solution of this utility model, the bottom of the pressing block is provided with a three-sided groove. In the installed state, the three-sided groove is pressed against the corner of the workpiece and covers the three end faces of the workpiece.

[0008] As a further technical solution of this utility model, a number of sets of slide tracks are equidistantly provided on the bearing surface of the processing table along the longitudinal direction, and the fixing component is slidably disposed in the slide tracks.

[0009] As a further technical solution of this utility model, the width of the slide gradually increases as it extends along the thickness direction of the processing table.

[0010] As a further technical solution of this utility model, the slide rail forms an opening at the end of the processing table along its laying direction.

[0011] As a further technical solution of this utility model, a slider is also connected to the bottom of the screw. The slider is slidably disposed in the slide rail. A locking ring is screwed onto the outside of the screw. In the installed state, the locking ring is pressed against the surface of the processing table to lock the screw.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) Sliding adjustable fixing components and slide system;

[0014] The machining table surface is equipped with multiple sets of equidistant slides along its length. The fixing components are slidably connected to the slides via sliders, allowing for flexible adjustment of the relative positions of the four fixing components according to the size of the square four-way connector or the machining position. This design overcomes the limitation of traditional fixtures where the fixing points are not adjustable, achieving universal adaptability to square four-way connectors of different specifications and significantly expanding the applicability of the fixture.

[0015] (2) Innovative design of three-sided groove pressing structure;

[0016] The three-sided groove at the bottom of the crimping block precisely fits the corners of the square four-way joint, simultaneously covering the three end faces of the workpiece, achieving three-dimensional positioning and fixation. Compared to traditional single-point or double-sided crimping, this structure effectively suppresses workpiece displacement and wobbling during processing, significantly improving fixation stability. It is particularly suitable for the high-precision processing requirements of multi-faceted workpieces such as square four-way joints.

[0017] (3) Optimized design of the slide structure;

[0018] The slide rail's width increases along the thickness of the machining table, forming a "wider inside, narrower outside" cross-sectional structure. This structure not only limits the vertical swaying of the fixed components during sliding but also prevents them from detaching from the slide rail, balancing sliding flexibility with structural stability. Furthermore, the open design at the end of the slide rail facilitates the disassembly, assembly, and repositioning of the fixed components, further enhancing operational convenience.

[0019] (4) The dual locking mechanism enhances the reliability of the fixation;

[0020] The fixing component is positioned by a slider at the bottom of the screw engaging with a slide rail, and then a locking ring screwed onto the screw presses against the surface of the processing table to achieve horizontal positioning. Simultaneously, after the pressing sleeve is tightened, it can press the pressing block downwards to achieve vertical clamping of the workpiece. This dual locking mechanism of "horizontal positioning + vertical clamping" ensures that the workpiece remains stable during processing, preventing displacement caused by vibration or other factors.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] Figure 1 A schematic diagram of the overall structure of the jig for machining a square four-way connector is shown; Figure 2 A schematic diagram of the processing table 100 is shown; Figure 3 A schematic diagram of the structure of the fixing component 200 is shown.

[0028] Figure 1 The jig for processing square four-way connectors includes a processing table 100 and four fixing components 200 mounted on the processing table 100. The processing table 100 is used to support the square four-way connector, and the four fixing components 200 are slidably mounted on the processing table 100. The position can be adaptively adjusted to fix the square four-way connector in four directions.

[0029] Figure 2 In the process table 100, several sets of slide rails 110 are equidistantly arranged along the longitudinal direction on the bearing surface. The fixing component 200 is slidably disposed in the slide rails 110. The slide rails 110 provide a trajectory for the movement of the fixing component 200, ensuring that the fixing component 200 and the process table 100 can change positions without disengaging from each other, in order to adapt to different placement angles of the square four-way. The width of the slide rail 110 gradually increases as it extends along the thickness direction of the process table 100. That is to say, in the cross-sectional shape of the slide rail 110, the interior of the slide rail 110 is wide and the opening is narrow, which can restrict the vertical movement of the fixing component 200 when sliding, and also prevent the fixing component 200 from vertically shaking after restricting the square four-way.

[0030] It should be noted that the slide rail 110 forms an opening at the end of the processing table 100 along its laying direction; so as to facilitate the fixing component 200 to slide into or out of the slide rail 110, thereby allowing the fixing component 200 to change its position by replacing different slide rails 110.

[0031] Figure 3In the process, the fixing component 200 includes a vertically arranged screw 210, a pressing block 220 slidably sleeved on the screw 210, and a pressing sleeve 230 screwed onto the screw 210. The pressing sleeve 230 is positioned above the pressing block 220. In the installed state, the pressing block 220 presses against the square four-way connector, and the pressing sleeve 230 presses against the upper surface of the pressing block 220. In actual operation, the fixing component 200 is driven to move as a whole, so that the four fixing components 200 enter different slides 110 from corresponding directions. Then, the fixing component 200 is driven to move to the side of the square four-way connector, so that the pressing block 220 presses against the surface of the workpiece. Then, the pressing sleeve 230 is rotated so that it is spirally pressed against the upper surface of the pressing block 220.

[0032] See also Figure 3 The bottom of the pressing block 220 has a three-sided groove 221. In the installed state, the three-sided groove 221 is pressed against the corner of the workpiece and covers the three end faces of the workpiece. With the special shape design of the three-sided groove 221, it can be specifically matched to the corner of the workpiece for pressing, and can restrict the workpiece from three directions, thereby fully locking the position of the workpiece.

[0033] See also Figure 3 The bottom of the screw 210 is also connected to a slider 240, which is slidably disposed in the slide rail 110. A locking ring 250 is screwed onto the outside of the screw 210. In the installed state, the locking ring 250 is pressed against the surface of the processing table 100 to lock the screw 210. The locking ring 250 and the slider 240 can form a fixed assembly clamped on the processing table 100 to limit the position of the screw 210 and lock the screw 210.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
