Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a limiting mechanism for positioning tooling. Background Technology

[0002] In machining, automated production, and various precision engineering fields, precise positioning and movement restriction of objects are crucial operational steps. Positioning fixtures, as important tools for achieving this goal, are widely used to ensure the stability and accuracy of mechanical parts or products during processing, transportation, and assembly. As the core component of positioning fixtures, the performance of the limiting mechanism directly affects the reliability and accuracy of the entire positioning system. However, existing positioning fixture limiting mechanisms are mainly fixed by bolts or clips, which is cumbersome and requires frequent bolt removal and installation, affecting processing efficiency. To solve these problems, a limiting mechanism for positioning fixtures is needed.

[0003] An existing positioning fixture limit mechanism is inconvenient to fix quickly during operation, requiring frequent bolt removal and installation, which affects processing efficiency. It also cannot protect the connection between the limit rod and the workpiece, and the hard contact between the limit rod and the workpiece can easily cause scratches on the surface of the workpiece, affecting product quality. Therefore, there is an urgent need for a positioning fixture limit mechanism. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a limiting mechanism for positioning fixtures, so as to solve the problems that existing positioning fixture limiting mechanisms are not convenient for quick fixation during use, require frequent disassembly and assembly of bolts, affecting processing efficiency, cannot protect the connection between the limiting top rod and the workpiece, and the rigid contact between the limiting top rod and the workpiece can easily cause scratches on the surface of the workpiece, affecting product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning tooling limiting mechanism, including a processing table, a fixed sleeve installed on the top of the processing table, a limiting groove formed on the side wall of the fixed sleeve, a limiting top rod installed on the inner wall of the fixed sleeve, an adjusting plate installed on the outer wall of the limiting top rod, and a limiting spring installed on the outer wall of the limiting top rod.

[0006] The outer wall of the limiting rod is fitted with a silicone sleeve, and the fixing shaft passes through the interior of the silicone sleeve.

[0007] Preferably, the limiting groove is L-shaped, and the limiting top rod is movably connected to the fixing sleeve.

[0008] Preferably, the adjusting plate is engaged with the limiting groove, and the limiting top rod forms a telescopic structure with the fixing sleeve through the limiting spring.

[0009] Preferably, the silicone sleeve is sleeved with the limiting top rod, and the silicone sleeve is elastically designed.

[0010] Preferably, the surface of the silicone sleeve is granular, and the fixing shaft passes through the interior of the silicone sleeve and is threadedly connected to the limiting rod.

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

[0012] 1. This utility model uses a processing table, a fixed sleeve, a limiting groove, a limiting rod, an adjusting plate, and a limiting spring. Pulling the adjusting plate causes the limiting rod to push forward. When the limiting rod is in contact with the workpiece, the adjusting plate is rotated 90 degrees to lock the adjusting plate into the limiting groove. After processing, the adjusting plate is rotated 90 degrees in the opposite direction. At this time, the limiting spring pushes the limiting rod backward through its elastic force, making it convenient to replace the workpiece. The entire operation does not require bolt fixing, making it convenient and efficient, and improving processing efficiency.

[0013] 2. This utility model uses a silicone sleeve and a fixed shaft to connect the silicone sleeve to the limiting rod. Then, the fixed shaft passes through the inside of the silicone sleeve and is threaded to the limiting rod, which facilitates the replacement of worn silicone sleeves. The silicone sleeve prevents hard contact between the limiting rod and the workpiece, thus avoiding scratches on the workpiece surface. At the same time, the surface of the silicone sleeve is granular, which increases friction and improves the stability of the connection. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figures 1-4 A positioning tooling limiting mechanism includes a processing table 1. The mechanism is characterized by: a fixed sleeve 2 mounted on the top of the processing table 1; a limiting groove 3 formed on the side wall of the fixed sleeve 2; a limiting rod 4 mounted on the inner wall of the fixed sleeve 2; an adjusting plate 5 mounted on the outer wall of the limiting rod 4; a limiting spring 6 mounted on the outer wall of the limiting rod 4; the limiting groove 3 being L-shaped; the limiting rod 4 being movably connected to the fixed sleeve 2; the adjusting plate 5 being engaged with the limiting groove 3; and the limiting rod 4 forming a telescopic structure with the fixed sleeve 2 via the limiting spring 6. The system consists of a processing table 1, a fixed sleeve 2, a limiting groove 3, a limiting rod 4, an adjusting plate 5, and a limiting spring 6. Pulling the adjusting plate 5 pushes the limiting rod 4 forward. When the limiting rod 4 is in contact with the workpiece, the adjusting plate 5 is rotated 90 degrees to engage and fix it with the limiting groove 3. After processing, the adjusting plate 5 is rotated 90 degrees in the opposite direction. At this time, the limiting spring 6 pushes the limiting rod 4 backward through its elastic force, making it convenient to change the workpiece. The entire operation does not require bolt fixing, making it convenient and efficient, and improving processing efficiency.

[0022] Please see Figures 1-4 A positioning tooling limiting mechanism is disclosed, wherein a silicone sleeve 7 is installed on the outer wall of a limiting rod 4, and a fixed shaft 8 passes through the interior of the silicone sleeve 7. The silicone sleeve 7 is sleeved with the limiting rod 4, and the silicone sleeve 7 is elastic with a granular surface. The fixed shaft 8 passes through the interior of the silicone sleeve 7 and is threadedly connected to the limiting rod 4. By using the silicone sleeve 7 and the fixed shaft 8 to sleeve the silicone sleeve 7 with the limiting rod 4, and then threading the fixed shaft 8 through the interior of the silicone sleeve 7 to the limiting rod 4, it is convenient to replace the worn silicone sleeve 7. The silicone sleeve 7 can prevent hard contact between the limiting rod 4 and the workpiece, which could cause scratches on the surface of the workpiece. At the same time, the granular surface of the silicone sleeve 7 increases friction and improves the stability of the connection.

[0023] Working principle: In use, first place the workpiece in the center of the processing table 1, then connect the silicone sleeve 7 to the limiting rod 4, and then thread the fixed shaft 8 through the inside of the silicone sleeve 7 to the limiting rod 4. This facilitates the replacement of worn silicone sleeve 7. The silicone sleeve 7 prevents hard contact between the limiting rod 4 and the workpiece, which could cause scratches on the workpiece surface. At the same time, the granular surface of the silicone sleeve 7 increases friction and improves the stability of the connection. Then, pull the adjusting plate 5 to push the limiting rod 4 forward. When the limiting rod 4 is in contact with the workpiece, rotate the adjusting plate 5 90 degrees to lock it into the limiting groove 3. After processing, rotate the adjusting plate 5 90 degrees in the opposite direction. At this time, the limiting spring 6 will push the limiting rod 4 backward through its elastic force, facilitating the replacement of the workpiece. The entire operation does not require bolt fixing, making it convenient and efficient, and improving processing efficiency. This completes the use of the device.
