Description

Technical Field

[0001] This utility model relates to the field of intelligent last pressing machine technology, specifically a positioning device for an intelligent last pressing machine. Background Technology

[0002] Intelligent last pressing machine is an automated equipment used in the shoemaking industry. It is mainly used for shaping, adjusting or processing shoe lasts. Shoe lasts are key molds used in the shoemaking process to fix the shoe shape and ensure that the shoes fit well. The function of the last pressing machine is to process or correct the shoe lasts through mechanical pressure. After the mold is placed on the placement table, it needs to be positioned by a positioning device to avoid the phenomenon of crookedness when pressing the shoe last.

[0003] Existing positioning devices have the following problems:

[0004] Most existing positioning devices use screws for positioning, which require knobs for both installation and disassembly, making positioning inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for an intelligent last pressing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for an intelligent pressing machine, comprising a placement platform, a backing plate fixed on the placement platform, a mold provided on the placement platform, a positioning device provided on the placement platform, the positioning device comprising a fixed base, a fixed base fixed in the placement platform, a rotating platform connected to the fixed base, a driven tooth assembled in the fixed base, a toothed rod connected in the fixed base, a connecting rod fixed at the end of the toothed rod, a pull plate fixed at the end of the connecting rod, and a locking structure provided in the fixed base.

[0007] Preferably, the locking structure includes a fixing plate, a fixing plate is fixed in the fixing seat, a fixing rod is connected to the fixing plate, a connecting plate is provided at the end of the fixing rod, a connector is fixed at the end of the connecting plate, and a press-rebound device is provided in the pull plate.

[0008] Preferably, the rotating table is L-shaped, and when the rotating table presses the mold, the top surface of the lower end of the rotating table is on the same plane as the top surface of the fixed seat, and the top surface of the lower end of the fixed seat is on the same plane as the lower end of the placement table.

[0009] Preferably, a spring is provided on the connecting rod.

[0010] Preferably, the spring is under stress when the connecting rod slides into the fixed seat.

[0011] Preferably, the fixed base is provided with a positioning rod inside, and the toothed rod is slidably connected to the positioning rod.

[0012] Preferably, the pull plate is provided with finger grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Place the mold on the rotating platform, then push the pull plate to push the connecting rod, causing the push gear to slide to the right. At this time, the driven gear rotates clockwise, which in turn drives the rotating platform to rotate clockwise. As the rotating platform rotates clockwise, the mold will naturally move downwards. Then the rotating platform presses on the surface of the mold and presses the mold against the surface of the backing plate to achieve convenient positioning of the mold. The connector is connected and fixed to the press rebound device, while the pull plate is fixed and limited. The "L"-shaped rotating platform can lift the mold when rotating counterclockwise to achieve the beneficial effect of convenient mold handling. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a positioning device for an intelligent pressing machine, including a placement platform 1, a backing plate 2 fixed to the rear end of the top surface of the placement platform 1 by screws, a mold 3 set on the placement platform 1, and a positioning device 4 set on the placement platform 1.

[0023] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a positioning device for an intelligent last pressing machine. The positioning device 4 includes a fixed base 41. The front end of the placement platform 1 is fixed to the fixed base 41 by bolts. A rotating platform 42 is rotatably connected to the fixed base 41. The rotating platform 42 is "L" shaped. When the rotating platform 42 presses the mold 3, the top surface of the lower end of the rotating platform 42 is on the same plane as the top surface of the fixed base 41, and the top surface of the lower end of the fixed base 41 is on the same plane as the lower end of the placement platform 1. This avoids the phenomenon that one end of the mold 3 will bulge after it is placed and positioned. Moreover, the "L" shaped rotating platform 42 can lift the mold 3 when it rotates counterclockwise, so as to achieve the beneficial effect of conveniently picking up the mold 3.

[0024] In this utility model, a driven tooth 43 is assembled in the fixed base 41, and the driven tooth 43 is fixed to the rotating table 42. A toothed bar 44 is connected in the fixed base 41, and the toothed bar 44 meshes with the driven tooth 43. A connecting rod 45 is fixed at the end of the toothed bar 44, and a pull plate 46 is fixed at the end of the connecting rod 45. A finger groove 410 is provided on the pull plate 46 to facilitate gripping the pull plate 46. A locking structure 47 is provided in the fixed base 41.

[0025] The locking structure 47 includes a fixing plate 471, which is vertically and slidably connected to the fixing base 41. A fixing rod 472 is fixed at the top of the fixing plate 471, and a connecting plate 473 is provided at the end of the fixing rod 472. A connector 474 is fixed at the end of the connecting plate 473. A press-and-rebound device 475 is provided in the pull plate 46. The connector 474 can be connected to the press-and-rebound device 475 and can be fixed in the press-and-rebound device 475 when pressed.

[0026] A spring 48 is provided on the connecting rod 45. One end of the spring 48 is fixed to the inside of the fixed seat 41, and the other end is fixed to the cross section of the rack 44. When the connecting rod 45 slides into the fixed seat 41, the spring 48 is under force, so that after the pull plate 46 is released from the limit, the rack 44 can be pulled to slide under the action of the spring 48, so that the rotating table 42 is slightly raised.

[0027] The fixed base 41 is equipped with a positioning rod 49 inside, and the toothed rod 44 is slidably connected to the positioning rod 49, which ensures the stability of the sliding of the toothed rod 44 and avoids the toothed rod 44 from becoming skewed.

[0028] Specifically, the mold 3 is placed on the rotating table 42, and then the pull plate 46 is pushed to push the connecting rod 45, so that the connecting rod 45 slides into the fixed seat 41. Then the toothed rod 44 is pushed to slide to the right. Since the toothed rod 44 is meshed with the driven tooth 43, when the toothed rod 44 slides, the driven tooth 43 will rotate clockwise, which will drive the rotating table 42 to rotate clockwise. When the rotating table 42 rotates clockwise, the mold 3 will move downward naturally. Then the rotating table 42 presses on the surface of the mold 3 and presses the mold 3 on the surface of the backing plate 2 to achieve convenient positioning of the mold 3. The connecting plate 473 is pressed down to make the fixed rod 472 slide with the fixed plate 471. Then the connector 474 is connected and fixed to the press rebound device 475 to achieve fixed limiting of the pull plate 46.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
