Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical design, and in particular relates to a positioning and stopping mechanism for a loading station. Background Art

[0002] Loading stations are widely used in automated manufacturing. As the exchange station between raw materials and finished products, their frequency of use and importance are self-evident. During automated production line operation, raw materials must be transported to the machine tool via the loading station for processing; similarly, the loading station is required to remove finished products from the machine tool. As a core component of the loading station, the positioning and stopping mechanism provides accurate positioning during loading and unloading operations. This prevents damage to the robot arm or loading station due to inaccurate material leveling. Furthermore, it prevents operator injuries caused by the unsecured loading station during manual loading and unloading. Therefore, a positioning and stopping mechanism is required to accurately position the loading station at each working point. This ensures that the loading station can maintain a stable material level for the robot arm, preventing accidents caused by material level shifting or inaccurate positioning, mitigating a range of risks and significantly improving automation efficiency.

[0003] In existing technologies, loading station positioning systems often use push-type handle locks to achieve this function. While these handle locks can achieve positioning and locking, they are inherently inaccurate and made of materials that easily wear out. This results in inaccurate loading station positioning, significant wobbling, and easily worn positioning components. This, in turn, leads to inaccurate gripping points for the robot, which can be easily damaged. Frequent maintenance also severely impacts production efficiency.

[0004] Existing push-button handle lock systems achieve a movable function by pressing an operating button to release a positioning rod from a positioning hole. A spring mounted on the positioning rod allows the rod to be inserted into its corresponding positioning hole, achieving a fixed position. While this patent provides a fixed position method, it has a complex structure, poor positioning performance, and the positioning parts are prone to wear, resulting in high costs.

[0005] The technical problem to be solved by the present invention is to provide a new positioning stop in response to the deficiencies in the above-mentioned prior art, which uses fewer parts to form a positioning mechanism, improves the processing accuracy and material wear resistance of key parts, and prevents large shaking of the output wire during the positioning process.

[0006] The utility model adopts the following technical solutions:

[0007] A loading station positioning and stopping mechanism comprises a positioning piece, a mounting seat and a push rod; the mounting seat is provided with a positioning piece mounting hole and a push rod sliding hole; the positioning piece is slidingly mounted in the positioning piece mounting hole, and the push rod is mounted in the push rod sliding hole; a cover plate is mounted on the mounting seat by screws, and a spring is provided between the cover plate and the positioning piece.

[0008] Furthermore, the positioning member is arranged in the form of a stepped shaft, including a cylindrical section at the end with the smallest diameter and a conical section in the middle that contacts the push rod. Two parallel planes are provided between the large cylindrical end and the middle conical section for positioning with the mounting seat, and the positioning member can slide in the mounting seat.

[0009] Furthermore, three countersunk holes are provided on the side surface of the large end of the positioning piece, which can be used for spring orientation.

[0010] Furthermore, the small end of the push rod is a conical surface, which is in line contact with the positioning piece, and the push rod can slide in the mounting seat.

[0011] Furthermore, a threaded hole is provided in the large end of the push rod, which can be used to connect with other operating handles.

[0012] Furthermore, a positioning step is provided on the inner side of the cover plate, and three spring positioning holes are provided on the positioning step.

[0013] Furthermore, three springs are provided between the positioning member and the cover plate.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] The utility model provides a new positioning stop mechanism, which uses fewer parts to form a positioning mechanism, improves the processing accuracy of key parts and the wear resistance of materials, and prevents large shaking of the outlet line due to excessive positioning.

[0016] Furthermore, the conical surface at the top of the push rod is in line contact with the conical surface in the middle section of the positioning part, driving the positioning part to slide in the mounting seat, and the cylindrical end of the positioning part cooperates with the positioning hole on the loading station to realize the positioning and stopping function; and the positioning part material has been treated to be extremely wear-resistant, positioning is accurate and not easy to damage.

[0017] Furthermore, a spring is provided between the positioning member and the cover plate, and the positioning member can be pushed outward by the elastic force of the spring, so that the positioning stop self-locking function can be realized in the absence of external force intervention.

[0023] See also Figure 1 and Figure 2 The utility model discloses a loading station positioning and stopping mechanism, which is characterized in that it includes a positioning member 3, a mounting seat 4 and a push rod 5; a positioning member mounting hole and a push rod sliding hole are provided on the mounting seat 4, the positioning member 3 is slidably installed in the positioning member mounting hole, and the push rod 5 is installed in the push rod sliding hole, the cover plate 1 is installed on the mounting seat 4, and a spring 2 is provided between the cover plate 1 and the positioning member 3.

[0024] The positioning member 3 is arranged in a stepped shaft, including a cylindrical section at the end with the smallest diameter, which cooperates with the corresponding circular hole on the mounting seat 3. The middle of the positioning member 3 is a conical section that contacts the push rod 5. The large end is a cylindrical section, and its end face is provided with 3 spring mounting holes. Two parallel planes are provided between the large end and the conical section, which are used to position with the mounting seat 4 to prevent the positioning member 3 from rotating during operation and the positioning member 3 from sliding in the mounting seat 4.

[0025] A circular hole is set on the mounting seat 4 perpendicular to the axis of the mounting hole of the positioning member 3. The axis of the circular hole is perpendicular to the axis of the mounting hole of the positioning member 3 and is in the same plane. A push rod 5 is set in the circular hole. The small end of the push rod 5 is a conical surface, which is in line contact with the conical surface of the middle section of the positioning member 3. The push rod 5 can slide forward in the mounting seat 4 with the help of external force, thereby pushing the positioning member 3 to slide backward. A threaded hole is set on one side of the large end of the push rod 5, which can be used to connect with other operating handles.

[0026] A contoured positioning step is provided on the inner side of the cover 1 to cooperate with the mounting hole of the positioning piece 3 on the mounting seat 4. Three spring positioning holes are provided on the positioning step. The cover 1 is connected to the mounting seat 4 through four M4 screws 6.

[0027] Three springs 2 are provided between the positioning member 3 and the cover plate 1. When the external force on the push rod is removed, the spring force pushes the positioning member 3, and the positioning member 3 pushes the push rod 5 to move outward. The positioning member 3 moves forward under the action of the spring thrust until the step surface of the small cylindrical end of the positioning member 3 fits into the inner wall of the sliding hole on the mounting seat 4. The small cylindrical end of the positioning member 3 extends from the corresponding circular hole on the mounting seat 4 and is inserted into the positioning hole of the loading station to realize the positioning stop function.

[0028] The implementation steps of the positioning and stopping mechanism of the loading station of the utility model are as follows:

[0029] Push the positioning piece 3 along the positioning piece mounting hole in the mounting base 4 to the bottom;

[0030] Insert the three springs 2 into the corresponding spring mounting holes on the positioning parts 3;

[0031] Install the spring 2 into the corresponding positioning hole of the spring 2 on the step surface of the cover plate. At the same time, align the positioning step surface on the cover plate 1 with the mounting hole of the positioning piece 3 on the mounting seat 4. Slowly press the cover plate 1 into the mounting seat 4 with force, and connect the cover plate 1 and the mounting seat 4 with screws 6;

[0032] Insert the small cylindrical end of the push rod 5 into the push rod mounting hole on the side of the mounting base 4.
