The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0054] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0055] A fast switching device for flexible tooling according to an embodiment of the utility model, such as Figure 2-7 The quick switching device for flexible tooling shown includes a support 1, a female unit 2, a male unit 3, a positioning assembly 4 and a locking assembly 5, the support 1 is connected to the workbench 100, the female unit 2 is detachably connected to the support 1, the male unit 3 is detachably connected to the female unit 2, and a special tooling 200 is connected to the male unit 3, the positioning assembly 4 is rotatably connected to the female unit 2, and is used to position the male unit 3, one end of the locking assembly 5 is connected to the female unit 2, and the other end of the locking assembly 5 is detachably connected to the positioning assembly 4, and the locking assembly 5 is used to lock the positioning assembly 4, wherein the locking assembly 5 and the positioning assembly 4 cooperate to configure the female unit 2 and the male unit 3 to be in an unlocked state or a locked state. The present application relates to a terminal quick switching device, which is an important subunit of the flexible tooling switching system, wherein the female unit 2 is fixed to the workbench 100 by a support 1, and the vehicle-specific tooling 200 is installed on the male unit 3, so that the flexible switching between vehicle-specific terminal actuators can be achieved simply by cooperating between the female unit 2 and the male unit 3. It should be noted that the workbench 100 in the present application can be a tooling frame 300 in an existing vehicle model or other convenient operating table, and the present application does not make any restrictions here; the special tooling 200 includes but is not limited to positioning fixtures, support fixtures, etc.; the female unit 2 and the male unit 3 are both provided with standard mounting holes to improve the compatibility of the female unit 2 and the male unit 3;

[0056] Figure 1 The flexible loading tooling in the prior art is shown. Figure 1It is not difficult to see that the special tooling 200 of the existing flexible loading tooling is connected to the cylinder 500, the cylinder 500 is fixed on the support 1, the support 1 is fixed on the tooling frame 300, and the tooling frame 300 is bolted to the ground or the operating table using the support 400. Due to factors such as the space occupied by the cylinder 500 and the installation holes on the support 1, the existing flexible loading tooling can only be compatible with 4 types of vehicle models. In addition, the positioning unit and the square cylinder are heavy, and the bolt pin installation direction is toward the inside of the tooling assembly, which is not conducive to manual disassembly and assembly, resulting in low switching efficiency. However, each switching unit of each vehicle model needs to be equipped with a cylinder and corresponding electrical components for control, which makes the switching cost of the existing flexible loading tooling high. The advantage of this application compared with the prior art is that this application shares the female unit 2 and only adds the male unit 3. Not only is the processing difficulty small, but also the male unit 3 can be quickly switched by manually opening the locking assembly 5, avoiding the situation where the cylinder 500 and the corresponding control components have to be added for each additional vehicle model, while avoiding the risk of key components being stuck. In addition, the present invention has a simple structure, stable, accurate and reliable performance, simple parts features, and is easy to process; the space is reasonable and easy to repair and replace.

[0057] In a preferred embodiment of the present invention, Figure 2-7 As shown, the male unit 3 includes a male body 31 and a plug connector 32 connected to the lower end of the male body 31, and the female unit 2 includes a female body 21, and the female body 21 is provided with a plug slot 211 corresponding to the plug connector 32, and the plug connector 32 can be inserted into the plug slot 211. When it is necessary to switch the special tooling 200, it is only necessary to pull out the plug connector 32 on the original male unit 3 from the plug slot 211, and then insert the plug connector 32 on the male unit 3 to be replaced into the plug slot 211. By adopting partial matching and avoiding full-surface matching, the processing cost and assembly difficulty are reduced, the structure is simple, the operation is convenient, and it is conducive to improving the work switching efficiency. Preferably, the male body 31 and the female body 21 are both L-shaped plates, the first vertical portion of the male body 31 is connected to the special tooling 200, the bottom of the horizontal portion of the male body 31 is connected to the plug connector 32, the top of the first vertical portion of the male body 31 is connected to the horizontal portion of the male body 31, and the horizontal portion of the male body 31 is provided with a plug slot 211.

[0058] In a preferred embodiment of the present invention, Figure 2-7 As shown, the positioning assembly 4 includes a positioning pin 41. The slot wall of the insertion slot 211 is provided with two mounting holes arranged opposite to each other. The axes of the two mounting holes are colinear. The positioning pin 41 can be inserted into the two mounting holes and can rotate around the axes of the mounting holes. Figure 2-7, mounting holes are respectively opened on two opposite groove walls of the plug-in groove 211, and the positioning pin 41 passes through the plug-in groove 211 and is inserted into the two mounting holes. The positioning pin 41 can rotate around the line connecting the centers of the two mounting holes. Preferably, the axes of the two mounting holes are colinear, so that the axis of the positioning pin 41 is perpendicular to the groove wall of the plug-in groove 211 with the mounting holes, which is convenient for processing and installation.

[0059] In addition, each mounting hole is connected with a first cushion block 212, and the mounting hole is fitted with a clearance between the first cushion block 212 and the positioning pin 41. On the one hand, the positioning pin 41 is prevented from falling out of the mounting hole, which affects the switching efficiency; on the other hand, the first cushion block 212 not only prevents the positioning pin 41 from being worn and affecting the product life, but also keeps the positioning pin 41 in a specific position after rotation. For example, when the male unit 3 and the female unit 2 need to be separated or assembled, the positioning pin 41 only needs to be rotated 90° to allow the male unit 3 to be smoothly removed or inserted. If there is an interference between the positioning pin 41 and the mounting hole, it will interfere with the insertion or separation of the male unit 3 and thus affect the switching efficiency.

[0060] In a preferred embodiment of the present invention, Figure 2-7 As shown, the longitudinal section of the positioning pin 41 is elliptical, the positioning pin 41 includes a plane section 411 and a curved section 412, the plane section 411 is parallel or perpendicular to the table surface of the workbench 100, so that the positioning pin 41 is configured to the first working position or the second working position. That is, the positioning pin 41 of the present application is a pin shaft with a flat position, the positioning pin 41 includes a plane section 411 and a curved section 412, the first working position refers to when the plane section 411 is parallel to the table surface of the workbench 100, at this time, the locking assembly 5 can lock the positioning pin 41 to prevent the positioning pin 41 from rotating, that is, the locking of the female unit 2 and the male unit 3 is achieved; when the plane section 411 is not parallel to the table surface of the workbench 100, the female unit 2 and the male unit 3 are in an unlocked state, and when the plane section 411 and the table surface of the workbench 100 are perpendicular, it is more convenient for the male unit 3 to smoothly escape from the female unit 2. Therefore, the second working position is that the plane section 411 is perpendicular to the table surface of the workbench 100. In this way, the positioning pin 41 can be switched from the first working position to the second working position by simply rotating 90°, which is simple and convenient to operate.

[0061] In a preferred embodiment of the present invention, Figure 2-7As shown, the locking assembly 5 includes a bracket 51 and a spring plunger 52, the bracket 51 is detachably connected to the female unit 2, one end of the spring plunger 52 is connected to the bracket 51, and the other end of the spring plunger 52 is detachably connected to the positioning pin 41, wherein the curved surface section 412 is provided with a groove 4121 corresponding to the spring plunger 52, so that when the positioning pin 41 is in the second working position, the other end of the spring plunger 52 is connected to the groove 4121 to achieve locking of the male unit 3 and the female unit 2. In this way, when the positioning pin 41 is in the second working position, the column of the spring plunger 52 can slide into the groove 4121 and cooperate with the spring plunger 52 to achieve automatic positioning and locking of the positioning pin 41, so that the automatic locking of the female unit 2 and the male unit 3 can be ensured, manual intervention can be reduced, and switching efficiency can be improved. The present application has a compact structure, reduces weight, and solves the problems of fastening and space.

[0062] In addition, in the present application, the two groove walls of the groove 4121 are inclined to the groove bottom, or the two groove walls of the groove 4121 are curved surfaces, which facilitates the spring plunger 52 to slide into or out of the groove 4121, so that the positioning pin 41 switches from the first working position to the second working position more smoothly, thereby improving the switching efficiency. Preferably, the two curved surface sections 412 on the positioning pin 41 are respectively provided with grooves 4121, and of course, through holes can also be provided in the two curved surface sections 412, as long as the spring plunger 52 can be limited, and the present application does not make any restrictions here.

[0063] In a preferred embodiment of the present invention, Figure 2-7 As shown, the plug connector 32 is provided with a limiting groove 321 corresponding to the positioning pin 41, and the limiting groove 321 cooperates with the positioning pin 41 so that the female unit 2 and the male unit 3 are configured in a locked state. When the female unit 2 and the male unit 3 are aligned and assembled, the positioning pin 41 is in the second working position. As the plug connector 32 is inserted into the plug slot 211, the positioning pin 41 is inserted into and abuts against the limiting groove 321; then, after rotating the positioning pin 4190°, the plane section 411 of the positioning pin 41 is in a horizontal state, at this time, a curved surface section 412 contacts the spring plunger 52, and the spring plunger 52 is inserted into the groove 4121, so as to realize the locking of the positioning pin 41. That is, through the cooperation of the limiting groove 321 and the two working positions of the positioning pin 41, the switching of the two states of positioning and tightening and disengagement and release of the male unit 3 can be realized, and the combination is simple and reasonable, and the operation is simple.

[0064] In a preferred embodiment of the present invention, Figure 2-7As shown, the limiting groove 321 includes a straight segment 3211 and an arc segment 3212, the straight segment 3211 is located at the open end of the limiting groove 321, the arc segment 3212 is located inside the limiting groove 321, the central angle of the arc segment 3212 is greater than 180°, and the outer diameter of the arc segment 3212 is the same as the major diameter of the positioning pin 41. Since the longitudinal section of the positioning pin 41 is an ellipse, when the head unit 2 and the male head unit 3 are aligned and assembled, the positioning pin 41 is in the second working position, at which time the plane segment 411 is perpendicular to the table surface of the workbench 100, and the limiting groove 321 and the positioning pin 41 can be inserted after the straight segment 3211 and the plane segment 411 are aligned. The central angle of the arc segment 3212 is greater than 180° and the outer diameter of the arc segment 3212 is the same as the major diameter of the locating pin 41. The two curved segments 412 of the locating pin 41 in the first working position can abut against the inner periphery of the limiting groove 321. In this way, the locating pin 41 can be initially fixed to the male head unit 3, and then the locking assembly 5 can be used to lock the locating pin 41 and the male head unit 3 to ensure the stability of the special tooling 200.
