Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument processing technology, and in particular to a positioner for processing high-pressure common rail parts. Background Technology
[0002] Positioners for machining high-pressure common rail parts are machining positioning tools used for various parts in high-pressure common rail systems. Their main function is to accurately fix the parts during the machining process, ensuring that the position and angle of the parts meet the machining requirements, and preventing machining errors caused by inaccurate positioning. These positioners are usually designed as multi-point positioning and adjustable types, which can adapt to high-pressure common rail parts of different shapes and sizes.
[0003] The main drawback of existing positioners for high-pressure common rail parts processing is that their distance is not adjustable. This limits their adaptability to parts of different sizes or shapes, requiring different positioners to accommodate various workpieces, increasing complexity and cost. Furthermore, the inconvenience of disassembling and replacing the positioning clamping head makes maintenance and repair cumbersome and time-consuming. Parts may wear or break after prolonged use, but due to the difficulty of disassembly, replacement requires more time for maintenance personnel, potentially impacting production efficiency and increasing equipment maintenance costs. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a positioner for processing high-pressure common rail parts, equipped with an adjustment mechanism including an adjustable connecting rod, a nut, and an auxiliary plate. This design enables the positioner to be adjusted according to parts of different sizes and shapes, solving the problem that existing positioners cannot adjust the distance when processing parts of different specifications. By rotating the nut, the operator can adjust the position of the connecting rod, thereby quickly adapting to the processing needs of different workpieces.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a positioning device for processing high-pressure common rail parts, including a parts processing platform, a worktable installed at the top of the parts processing platform, a processing table installed on the worktable, a base installed on the outer wall of the worktable, a positioning device movably connected to the upper end of the base, an adjustment mechanism provided on the side wall of the base, a disassembly mechanism provided on the upper side wall of the positioning device, and a positioning clamping head fixedly installed at the upper end of the positioning device through the disassembly mechanism.
[0006] As a preferred technical solution of this utility model, the adjustment mechanism includes two sets of first sliding grooves opened in the base, a slider slidably connected in the first sliding groove and fixed to the bottom end of the positioning device, a movable cavity opened in the side wall of the base, a connecting rod connected to the slider and disposed in the movable cavity, an external thread opened in the outer wall of the connecting rod, a nut threaded to the external thread, an auxiliary plate fixed to the outer ends of the two sets of connecting rods, and a gripping rod fixed to the outer wall of the auxiliary plate.
[0007] As a preferred technical solution of this utility model, four sets of sliders are symmetrically fixed at the bottom of the positioning device, and two sets of sliders are slidably connected in the first groove of each set.
[0008] As a preferred embodiment of this utility model, two sets of connecting rods are provided in the movable cavity. The inner end of each set of connecting rods is fixed to the corresponding slider, and the outer end of each set of connecting rods is connected to the inner wall of the auxiliary plate.
[0009] As a preferred embodiment of this utility model, the grip is fixed at the middle position of the auxiliary plate, and the outer wall of the grip is provided with anti-slip texture.
[0010] As a preferred technical solution of this utility model, the disassembly mechanism includes a mounting plate fixed on both sides of the outer wall of the positioning clamping head, a second sliding groove opened on the inner wall of the mounting plate, a second slider slidably connected to the inner wall of the second sliding groove, a limiting rod connected to the second slider and inserted into the mounting plate, a limiting groove opened in the positioning device and inserted into the limiting rod, a reset spring wound on the outer wall of the limiting rod, and a pull rod fixed on the outer end wall of the limiting rod.
[0011] In a preferred embodiment of this utility model, one end of the reset spring is connected to the outer wall of the second slider, and the other end of the reset spring is connected to the outer wall of the limiting rod.
[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are: This positioner is equipped with an adjustment mechanism, including an adjustable connecting rod, nut, and auxiliary plate. This design allows the positioner to be adjusted according to the size and shape of parts, solving the problem that existing positioners cannot adjust the distance when processing parts of different specifications. By turning the nut, the operator can adjust the position of the connecting rod, thus quickly adapting to the processing requirements of different workpieces. This function effectively improves the adaptability of the tool, reduces the dependence on multiple positioners, and saves equipment investment and operational complexity.
[0013] The adjustment process of the positioner is very simple. The operator only needs to turn the nut to release the limit and then pull the lever to move the auxiliary plate and connecting rod, thereby adjusting the position of the positioning device. After the adjustment is completed, the position of the connecting rod is fixed by turning the nut in the opposite direction. This mechanism reduces the complexity of the positioning device adjustment process and greatly improves the convenience and efficiency of operation. Especially in production environments with high-frequency adjustments, it greatly reduces the risk of human error. Attached Figure Description

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0018] Example: like Figure 1-5 As shown, a positioning device for processing high-pressure common rail parts includes a parts processing platform 1, a worktable 2 installed at the top of the parts processing platform 1, a processing table 3 installed on the worktable 2, a base 5 installed on the outer wall of the worktable 2, a positioning device 4 movably connected to the upper end of the base 5, an adjustment mechanism 6 provided on the side wall of the base 5, a disassembly mechanism 7 provided on the upper side wall of the positioning device 4, and a positioning clamping head 8 fixedly installed on the upper end of the positioning device 4 through the disassembly mechanism 7. The adjustment mechanism 6 includes two sets of first slide grooves 61 opened in the base 5, a slider 62 slidably connected in the first slide grooves 61 and fixed to the bottom end of the positioning device 4, a movable cavity 63 opened on the side wall of the base 5, a connecting rod 64 connected to the slider 62 and disposed in the movable cavity 63, an external thread 65 opened on the outer wall of the connecting rod 64, a nut 66 threadedly connected to the external thread 65, an auxiliary plate 67 fixed on the outer ends of the two sets of connecting rods 64, and a gripping rod 68 fixed on the outer wall of the auxiliary plate 67. Four sets of sliders 62 are symmetrically fixed at the bottom of the positioning device 4, and two sets of sliders 62 are slidably connected in the first groove 61 of each set.
[0019] When the operator needs to adjust the position of the positioning device 4, first turn the nut 66 outward so that the nut 66 and the external thread 65 cooperate to turn outward until the inner wall of the nut 66 separates from the outer wall of the base 5, releasing the restriction on the two sets of connecting rods 64. At this time, simply hold the handle 68 and pull it, thereby driving the auxiliary plate 67 to move. The auxiliary plate 67 simultaneously drives the two sets of connecting rods 64 connected to it to move. The two sets of connecting rods 64 drive the two sets of sliders 62 connected to them to move. The two sets of sliders 62 drive the positioning device 4 to move. The positioning device 4 slides in the two sets of first slide grooves 61 through the four sets of sliders 62, thereby adjusting the position. After the adjustment is completed, turn the two sets of nuts 66 in the opposite direction so that the two sets of nuts 66 fit against the outer wall of the base 5 to form a fixed position, fixing the position of the two sets of connecting rods 64, and further fixing the position of the positioning device 4. It is worth noting that there are two sets of connecting rods 64 in the movable cavity 63. The inner end of each set of connecting rods 64 is fixed to the corresponding slider 62, and the outer end of each set of connecting rods 64 is connected to the inner wall of the auxiliary plate 67. This is mainly to ensure the synchronous movement of each component in the adjustment mechanism 6. With this structure, when the operator pulls the lever 68, the auxiliary plate 67 can smoothly drive the connecting rods 64 to move, thereby ensuring that the positioning device 4 slides smoothly and symmetrically in the two slides. This can effectively avoid component offset or asymmetrical movement and maintain adjustment accuracy. The grip 68 is fixed in the middle of the auxiliary plate 67. The outer wall of the grip 68 is provided with anti-slip texture to improve the operator's ease of use and control, and to ensure that the hand can hold it firmly and adjust the position smoothly.
[0020] The disassembly mechanism 7 includes a mounting plate 71 fixed on both sides of the outer wall of the positioning clamping head 8, a second slide groove 72 opened on the inner wall of the mounting plate 71, a second slider 73 slidably connected to the inner wall of the second slide groove 72, a limiting rod 74 connected to the second slider 73 and inserted into the mounting plate 71, a limiting groove 75 opened in the positioning device 4 and inserted into the limiting rod 74, a return spring 76 wound on the outer wall of the limiting rod 74, and a pull rod 77 fixed on the outer end wall of the limiting rod 74. When the staff disassembles the positioning clamp head 8 for maintenance or replacement, they only need to pull the pull rod 77 outward, so that the pull rod 77 drives the limit rod 74 to move outward. The limit rod 74 then slides outward in the second slide groove 72 through the second slider 73. During the sliding process, the return spring 76 is compressed and deformed until the inner end of the limit rod 74 moves out of the limit groove 75 and into the mounting plate 71, releasing the fixation between the positioning clamp head 8 and the positioning device 4. At this time, the positioning clamp head 8 and the mounting plate 71 can be removed from the positioning device 4 for replacement or maintenance. It is worth noting that one end of the return spring 76 is connected to the outer wall of the second slider 73, and the other end of the return spring 76 is connected to the outer wall of the limit rod 74, which improves the smoothness and convenience of disassembly operation, and at the same time ensures that the limit rod can automatically return to its original position when not in operation, keeping the parts in a fixed state and preventing the equipment from becoming loose or unstable.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
