Description

TECHNICAL FIELD

[0001] The utility model relates to an adjusting device, in particular to a clamping jaw opening and closing translation adjusting device of a clamping machine. BACKGROUND

[0002] Referring to Figure 1 The clamping jaw device 1 of the general clamping machine comprises a driving assembly 11, a core rod 12 coaxially arranged on the driving assembly 11, a receiving seat 13 connected to the bottom end of the core rod 12, a plurality of claw bodies 14 arranged in a ring shape at equal angles and spaced from each other and pivoted to the receiving seat 13, and a plurality of connecting rods 15 respectively connected to the claw bodies 14 and the driving assembly 11. The driving assembly 11 can drive the core rod 12 to stretch and contract relative to itself through the internal coil to move the receiving seat 13 upward and downward. When the receiving seat 13 moves upward to the highest position, one end of each claw body 14 pivoted to the receiving seat 13 also rises, which makes the claw body 14 swing with the pivoted place of the corresponding connecting rod 15 and the claw body 14 as the fulcrum, so that the other end of the claw body 14 not connected to the receiving seat 13 extends downward and inward. The claw bodies 14 can achieve the action of closing claws by cooperating with each other. Conversely, when the receiving seat 13 moves downward to the lowest position, the claw body 14 will open outward to achieve the action of opening claws. However, the opening and closing degree of the claw body 14 of the clamping jaw device 1 of this design is limited and can only have one size, so when different sizes and large volume prizes are put into the clamping machine, different opening and closing degree clamping jaw devices 1 need to be replaced to correspond, which is extremely high in cost and very inconvenient.

[0003] Referring to Figure 2Therefore, a jaw opening degree adjusting device is disclosed in Taiwan Utility Model Patent No. M653297. The device includes a spring 161 sleeved on a core rod 12, and an adjusting piece 162 sleeved on the core rod 12 between the spring 161 and a receiving seat 13. The adjusting piece 162 is in a disc shape, and has grooves 163 of different depths formed on the outer circumferential surface from the outside to the inside along the radial direction. The grooves 163 are divided into groups according to the number of jaw bodies 14, and the grooves 163 in the same group have different depths. Therefore, the grooves 163 in each group are aligned with one of the jaw bodies 14 along the radial direction, and the depth of each groove 163 affects the upper dead point of the jaw body 14. Therefore, the opening degree of the jaw body 14 can be adjusted by rotating the adjusting piece 162. However, the device has the following problems. Although the spring 161 is arranged to press the adjusting piece 162 along the axial direction to limit the height position of the adjusting piece 162, the adjusting piece 162 cannot be limited in rotation when none of the jaw bodies 14 is arranged in the groove 163. That is, the adjusting piece 162 is easily rotated by external force or vibration, which causes the groove 163 to be deviated from the jaw body 14, and the jaw body 14 can only have a minimum opening degree due to the blocking of the adjusting piece 162. In severe cases, the adjusting piece 162 can be concave due to the force of the jaw body 14. In addition, the adjusting piece 162 can only have the grooves 163 arranged on the outer circumferential surface. In consideration of the strength, the adjacent grooves 163 cannot be arranged too close to each other. Therefore, the number of the grooves 163 is limited, and the number of the segments that can be adjusted is also limited, which causes the problem of lacking of adjustment flexibility.

[0004] Referring to Figure 3 Taiwan Utility Model Patent No. I8009264 provides another design. The adjusting piece 162 is designed in a polygonal shape corresponding to the number of the jaw bodies 14, and has a plurality of through holes 164 arranged along the circumferential direction. A blind hole 131 having a spring 171 is arranged in the receiving seat 13, and a plug rod 172 is arranged in the blind hole 131. When the plug rod 172 is aligned with one of the through holes 164, the spring 171 pushes the plug rod 172 upward to be arranged in the through hole 164, so that the adjusting piece 162 can be positioned. Therefore, the jaw bodies 14 can be blocked by the geometric shape of the adjusting piece 162 to adjust the opening degree. However, the plug rod 172 needs to be pressed by a thin needle tool to be removed from the through hole 164, and then the adjusting piece 162 can be rotated. The plug rod 172 is thin and difficult to align and press, and the operation is difficult. In addition, the tool needs to be carried and used, which is not convenient. Utility model content

The core plate part 321 is opened to a long slot 325. The core plate part 321 has three outer circumferential surfaces 326 respectively located between two embankment parts 322. The spring part 323 is located in the long slot 325 and integrally connected to one end of the core plate part 321, and the positioning part 324 is integrally protruded from the other end of the spring part 323. The adjusting plate 32 is made of a material that has elastic restoring force after deformation, so that when the spring part 323 is forced to lift or fold relative to the adjusting plate 32, it will reset by elastic restoring force after unforced. In practice, the material of the adjusting plate 32 can be metal and formed by stamping. The embankment parts 322 are divided into three groups in five groups, and any two groups of embankment parts 322 are connected by one of the outer circumferential surfaces 326.
