DETAILED DESCRIPTION

[0022] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

They do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.

[0025] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0026] like Figure 1 、 2 The shown embodiment shows an infinitely rotating clamping platform that can move forward and backward, comprising a rotating group 1, a clamping body 1-1 respectively connected to one side of the rotating group 1, and a cylinder 121 connected to the other side of the rotating group 1 through a screw 110. The embodiment is characterized in that the rotating group 1 comprises a hollow shaft stepping motor 122, a push rod 114 passing through the hollow shaft stepping motor 122, the clamping body 1-1 comprises a right connecting rod 118, a clamping jaw 19 coaxially hinged to the right connecting rod 118, one end of the push rod 114 is connected to the screw 110, and the other end sleeve of the push rod 114 is coaxially connected to the right connecting rod 118, the bottom of the rotating group 1 and the bottom of the cylinder 121 are fixedly connected to the middle plate 124, and the middle plate 124 is slidably arranged on the sliding base 2.

[0027] like Figure 2 The air joint 11 shown is screwed and locked above the cylinder 121. The cylinder 121 is fixed to the cylinder plate 112 by bolts. The cylinder plate 112 is fixed to one end of the intermediate plate 124. The end of the piston rod of the cylinder 121 is screwed and locked with the screw 110. The other end of the screw 110 is connected to the bearing sleeve 115. The bearing sleeve 115 is fixedly connected to the shaft sleeve 113 by bolts, and a bearing 123 is installed in the middle. One end of the push rod 114 is sleeved with an oil-free bushing 119 and is coaxially connected to the inner hole of the bearing sleeve 115. The push rod 114 passes through the hollow shaft stepper motor and is sleeved with an oil-free bushing at the other end and is coaxially connected to the right connecting rod 118. The right connecting rod 118 is coaxially hinged to the clamping jaw 19 through the middle pin 111. The two ends of the connecting piece 14 A clamping plate 17 is fixed at one end, and a wear-resistant pin 120 with an edge is inserted into each of the two circular holes at the other end of the clamping plate 17. The wear-resistant pin 120 with an edge is hinged in the middle of the clamping jaw 19 and the right connecting rod 118. The central opening circular hole of the connecting member 14 is connected to the rotating shaft at one end of the hollow shaft stepper motor 122. When the shaft of the hollow shaft stepper motor 122 rotates, the clamping jaw 19 is driven to rotate together. The hollow shaft stepper motor 122 is fixedly connected to the stepping plate 16 by bolts, and the lower part of the stepping plate 16 is fixed to the middle plate 124 by bolts. The rib plate 125 is fixedly connected to the stepping plate 16 and the middle plate 124 at the same time. The middle baffle 13 is connected to the middle plate 124 by screws, and the sliding sleeve 18 is fixed below the middle plate 124.

[0028] Among them, the push rod 114 is pushed out synchronously when the piston rod of the cylinder 121 is pushed out. The other end of the push rod 114 is hingedly connected to the right connecting rod 118. The right connecting rod 118 pushes the clamping jaw 19 to rotate around the edge wear-resistant pin 120 to realize the clamping action of the clamping jaw 19.

[0029] Secondly, the rotation of the rotating shaft of the hollow shaft stepper motor 122 will drive the connecting part 14 to rotate together. The connecting part 14 fixes the clamping claw plate 17. The clamping claw plate 17 drives the clamping claw 19 to rotate together through the edge wear-resistant pin 120 to realize the rotation of the clamping claw 19. At the same time, the required clamping force and rotational torque can be obtained by using the cylinder 121 and the hollow shaft stepper motor 122.

[0030] like Figure 3 The sliding base 2 shown in the figure contains two guide rails 21, and the two lower parts of the guide rails 21 are respectively connected to the side panels 24 and the left side panels 23. The sensor guide rail 213 is fixed to the side of the left side panel 23 by bolts. The slot-shaped photoelectric 26 is fixed to the sensor guide rail 213. One end of the screw rod 210 is coaxially connected to the screw rod fixing seat 212 and the other end is coaxially connected to the screw rod support seat 211. The screw rod connecting plate 25 is coaxially connected to the nut in the middle of the screw rod 210. The screw rod fixing seat 2 12 is fixed to the screw plate 28 by screws, and the screw plate 28 is fixed to one end of the side plate 24 and the left side plate 23. The screw support seat 211 is installed on the end plate 27 by screws, and the end plate 27 is fixed to the other end of the side plate 24 and the left side plate 23. The control motor 22 is fixed to the motor plate 214, and the motor plate 214 is fixed to the side plate 24 and the left side plate 23. One end of the coupling 29 is coaxially connected to the output shaft of the control motor 22, and the other end is coaxially connected to the screw 210.

[0031] First, the rotation of the shaft of the control motor 22 is transmitted to the screw rod 210 through the coupling 29. The rotation of the screw rod 210 drives the nut on the screw rod 210 to move, and the screw rod connecting plate 25 fixed on the nut of the screw rod 210 will also move synchronously. The upper part of the screw rod connecting plate 25 is inserted into the sleeve 18 in the clamping rotation group 1, so that the sleeve 18 moves synchronously, and the movement of the sleeve 18 will drive the clamping rotation group 1 to move synchronously.

[0032] Secondly, the corresponding forward and backward movement speed and force can be obtained through the screw rod 210 and the control motor 22.

[0033] like Figure 4 As shown, the sausage 3 is clamped by the clamping claw body 1-1 and accurately positioned forward. After the aluminum buckle is reliably clamped, the casing is twisted off and accurately retreated to above the aluminum buckle recovery point. The clamping claw is released and the aluminum buckle falls off.

[0034] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0035] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
