DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "left" and "right" in the present invention are all based on Figure 1 For reference direction:

[0018] like Figure 1 to Figure 4 As shown, a parts line changing device is used to transfer the parts on the first parts assembly line 91 to the second parts assembly line 92 (in the application scenario of the present utility model, the first parts assembly line 91 and the second parts assembly line 92 are arranged in parallel, the installation height of the first parts assembly line 91 is lower than that of the second parts assembly line 92, the parts first circulate on the first parts assembly line 91, and need to be grabbed and placed on the second parts assembly line 92 for circulation), which includes a fixed base plate 1, a lifting sleeve 3, a lifting drive mechanism 4 and a rotary drive assembly 5, the fixed base plate 1 is used to enable the device to be fixedly installed on the workshop floor, a column 2 is fixedly installed on the fixed base plate 1, and the lifting sleeve 3 is sleeved on the outside of the column 2 The column 2 plays a role in guiding the movement of the lifting sleeve 3. The lifting sleeve 3 can perform lifting and lowering movements along the height direction of the column 2. The lifting drive mechanism 4 and the rotary drive assembly 5 are both transmission-connected to the lifting sleeve 3. Under the cooperation of the lifting drive mechanism 4 and the rotary drive assembly 5, the lifting sleeve 3 can simultaneously complete the lifting and lowering and ninety-degree rotation movements. An extension arm 6 is fixedly connected to the outer wall of the lifting sleeve 3. A part gripper 7 is installed at the outer end of the extension arm 6. The part gripper 7 is used to grab parts. When the lifting sleeve 3 moves, the lifting and lowering and ninety-degree rotation movements of the part gripper 7 can be realized. The part gripper 7 can just correspond to the switching movement back and forth between the two part production lines to realize the part line change operation requirements.

[0019] like Figure 1 and Figure 3As shown, the lifting drive mechanism 4 includes a first lifting frame 41 and a first lifting push cylinder 43. The first lifting frame 41 is installed on the fixed base plate 1. A T-shaped slide 42 is movably installed in the first lifting frame 41. The first lifting push cylinder 43 is installed on the top of the first lifting frame 41. The T-shaped slide 42 is connected to the piston rod end of the first lifting push cylinder 43. The T-shaped slide 42 can perform vertical lifting movement under the drive of the first lifting push cylinder 43. A clamping plate seat 421 is connected to the T-shaped slide 42. A flange disk 31 is connected to the top of the lifting sleeve 3. The flange disk 31 is plug-connected to the clamping plate seat 421. When the T-shaped slide 42 is lifted and lowered, the lifting sleeve 3 can realize vertical lifting movement through the cooperation of the clamping plate seat 421 and the flange disk 31. Due to the plug-in connection, the clamping plate seat 421 only realizes the lifting and lowering movement effect of the lifting sleeve 3, and does not affect the rotation effect of the lifting sleeve 3 (that is, the flange disk 31 can rotate in the clamping plate seat 421).

[0020] like Figure 1 As shown, the rotary drive assembly 5 includes a side plate 51 and a steering pin 52. The side plate 51 is fixedly mounted on the side of the lifting sleeve 3, and the steering pin 52 is fixedly connected to the side plate 51. A rotary drive groove 32 is opened on the outer wall of the lifting sleeve 3. The rotary drive groove 32 is in a curved and coiled shape. The steering pin 52 is plugged and connected in the rotary drive groove 32. When the lifting sleeve 3 moves up and down, the steering pin 52 can move in the rotary drive groove 32. Since the rotary drive groove 32 is curved and coiled, the entire lifting sleeve 3 can achieve a rotary effect under the drive of the steering pin 52. The lifting sleeve 3 moves up or down once, and the steering pin 52 travels a complete stroke in the rotary drive groove 32. At this time, the lifting sleeve 3 can just rotate ninety degrees. The initial state of the lifting sleeve 3 is at the low point. At this time, the part gripper 7 is at the first part assembly line 91 position. When the lifting sleeve 3 is lifted to the upper limit, the part gripper 7 will just turn ninety degrees, and it is in the second part assembly line 92.

[0021] like Figure 1 As shown, the part gripper 7 includes a first clamping piece 71 and a second clamping piece 72. The first clamping piece 71 and the second clamping piece 72 are both rotatably mounted on the extension arm 6. The first clamping piece 71 and the second clamping piece 72 are symmetrically mounted. A tensioning spring 73 is connected between the first clamping piece 71 and the second clamping piece 72. The tensioning spring 73 is mounted at the upper point of the clamping part of the clamping piece. Under the action of the tensioning spring 73, the first clamping piece 71 and the second clamping piece 72 can form a clamping effect and can grasp the parts.

[0022] like Figure 1As shown, an automatic unloading assembly 21 is installed on the top of the column 2, and the automatic unloading assembly 21 includes a fixed cross plate 211, one end of the fixed cross plate 211 is fixedly connected to the top of the column 2, and two clamp opening striker rods 212 are connected to the lower end surface of the fixed cross plate 211. The two clamp opening striker rods 212 are respectively arranged corresponding to the first clamp piece 71 and the second clamp piece 72. The clamp handles of the first clamp piece 71 and the second clamp piece 72 can contact and strike the two clamp opening striker rods 212. When the part gripper 7 is lifted, the part can be grabbed to the second part assembly line 92 position. When it is lifted to the highest point, the clamp opening operation needs to be completed to achieve In order to prevent the part from falling and landing on the second part assembly line 92, the utility model arranges the two opening jaws and striking rods 212 on the fixed horizontal plate 211 at the high points of the travel of the first clamp piece 71 and the second clamp piece 72 respectively. When the part gripper 7 runs to the high point, the clamp handles of the first clamp piece 71 and the second clamp piece 72 just contact and hit the two opening jaws and striking rods 212. During the impact process, the first clamp piece 71 and the second clamp piece 72 are simultaneously expanded and squeezed outward to overcome the tensioning spring 73, so that the part gripper 7 is released from the clamping state. At this time, the part falls naturally and lands on the second part assembly line 92.

[0023] There is a need to grasp the parts at the first part assembly line 91. To achieve the grasping, the part gripper 7 at the first part assembly line 91 also needs to be able to open and close automatically. Figure 2 and Figure 4 As shown, a material picking opening and closing mechanism 8 is installed at the position of the first parts assembly line 91, and the material picking opening and closing mechanism 8 includes a second lifting frame 81 and a second lifting push cylinder 82. The second lifting push cylinder 82 is fixedly installed on the top of the second lifting frame 81, and the piston rod end of the second lifting push cylinder 82 is connected to a lifting cross plate 83. The extension and contraction of the piston rod of the second lifting push cylinder 82 can drive the lifting cross plate 83 to do lifting movement. The side of the lifting cross plate 83 is connected to two parallel opening and closing driving plates 831, and each opening and closing driving plate 831 is connected to an opening clamp striker 212. The two opening clamp strikers The rod 212 can also correspond to the first clamp piece 71 and the second clamp piece 72 of the part gripper 7. When the lifting horizontal plate 83 moves downward, the two clamp opening impact rods 212 can hit the clamp handles of the first clamp piece 71 and the second clamp piece 72, prompting the part gripper 7 to open. At this time, the part can fall into the clamping range. After the lifting horizontal plate 83 moves upward, the clamp handles of the first clamp piece 71 and the second clamp piece 72 lose external tension. Under the action of the tensioning spring 73, the part gripper 7 can be naturally tightened to achieve the purpose of clamping the parts. At this time, the subsequent line changing operation can be carried out.

[0024] The part gripper 7 of the present invention can simultaneously complete the lifting movement and the ninety-degree rotation movement. When the part gripper 7 is at the low point, it corresponds to the position of the first part assembly line 91, and can complete the automatic grabbing operation of the part. When the part gripper 7 moves to the high point, it corresponds to the position of the second part assembly line 92, and can automatically complete the unloading operation of the part. With the reciprocating motion of the part gripper 7, the parts of the first part assembly line 91 are continuously grabbed and placed on the second part assembly line 92. The utility model has the advantage of a high degree of automation, and no manual cooperation is required throughout the whole process. The application of the utility model can greatly reduce the use of manual labor and meet the needs of automated and unmanned production in the workshop.
