[0001] The invention relates to the technical field of mechanical equipment, and in particular to a quick positioning clamping device. [Background technology]

[0002] At present, rubber frames are widely used as seals in electronic equipment, automobiles, trains, and industries. In production, a vacuum suction cup is usually used to pick up the rubber frame. It is necessary to ensure that the central axis of the vacuum suction cup picking mechanism coincides with the central axis of the rubber frame to be picked up. Although the picking position of the vacuum suction cup is fixed, the rubber frame needs to be repeatedly replenished after it is picked up. Each time the material is replenished, the central axis of the frame to be picked up needs to be accurately positioned to facilitate the vacuum suction cup to pick up the material. The operation is cumbersome and seriously affects the production efficiency. In view of this, it is necessary to provide a quick positioning clamping device to overcome the above defects.

It should be understood that the specific implementation methods described in this specification are only for explaining the present invention, not for limiting the present invention.

[0022] See also Figures 1 to 3 The embodiment of the present invention provides a rapid positioning clamping device, including a base 10, a storage tool 20 and a positioning mechanism 30 arranged on the base 10. The storage tool 20 includes a storage rack 21 and a support plate 22 accommodated in the storage rack 21, the support plate 22 is used to stack at least one workpiece 201, and the storage rack 21 includes at least one fixing member 211 protrudingly arranged along the outer periphery of the storage rack 21. The positioning mechanism 30 includes a first clamping block 31 and a second clamping block 32, the fixing member 211 is limited between the first clamping block 31 and the second clamping block 32, and a magnetic member 2111 that attracts the first clamping block 31 and the second clamping block 32 is provided in the fixing member 211.

[0023] In this embodiment, the first clamp block 31 and the second clamp block 32 are made of ordinary carbon steel, and the magnetic member 2111 is a magnet. It can be understood that the quick positioning clamping device cooperates with the material picking mechanism 50, and the material picking mechanism 50 is provided with a plurality of vacuum suction cups 51 for sucking the workpiece 201 on the supporting plate 22, and the workpiece 201 is specifically a rubber frame. The dimensions of the supporting plate 22 and the workpiece 201 are matched, and when the positioning mechanism 30 limits the fixing member 211, the central axis of the workpiece 201 to be picked up can be consistent with the central axis of the material picking mechanism 50 (the deviation does not exceed ±0.2mm).

[0024] Specifically, the storage rack 21 further includes a bottom plate 212 placed on the base 10 and a plurality of levers 213 arranged perpendicular to the bottom plate 212. The plurality of levers 213 are arranged at intervals to limit the support plate 22 between the plurality of levers 213. Each lever 213 is provided with a step 2131 for supporting the support plate 22. In this embodiment, the number of levers 213 is four and they form a rectangular frame structure.

[0025] The fixing member 211 is disposed outside the plurality of levers 213 and fixed on the levers 213. The fixing member 211 is a semi-frame structure. The levers 213 and the bottom plate 212 are fixedly connected via angle seats 214. In this embodiment, the angle seats 214 are L-shaped structures, and the fixing member 211 is made of aluminum alloy.

[0026] Preferably, a fixing groove 2132 is provided on the shift rod 213 along the longitudinal direction of the shift rod 213 , a T-shaped nut is provided in the fixing groove 2132 , and the fixing member 211 is connected and fixed to the T-shaped nut by bolts.

[0027] Preferably, there are multiple fixing members 211 and they are spaced apart in sequence along the longitudinal direction of the lever 213. Handles 2112 are provided on both sides of one of the fixing members 211 to facilitate the movement of the storage tooling 20. For example, after the workpiece 201 is taken out, the storage tooling 20 can be manually pulled out through the handles 2112.

[0028] Further, such as Figure 3 As shown, the positioning mechanism 30 also includes a clamping seat 33 fixed on the base 10, a cross bar 34 fixed on the clamping seat 33, and a first slider 35 and a second slider 36 provided on the cross bar 34. The first slider 35 and the second slider 36 can slide along the cross bar 34. The first slider 35 is provided with a slidable first slider 37, and the second slider 36 is provided with a slidable second slider 38. The first clamping block 31 is fixed to a side of the first slider 37 close to the storage rack 21, and the second clamping block 32 is fixed to a side of the second slider 38 close to the storage rack 21. In this embodiment, the first slider 35 and the second slider 36 are both sleeved on the cross bar 34.

[0029] Preferably, the first slide bar 37 and the second slide bar 38 are perpendicular to the cross bar 34, that is, the first slide bar 37 and the second slide bar 38 can slide in a direction perpendicular to the cross bar 34, and a scale 39 is attached to the cross bar 34, the first slide bar 37 and the second slide bar 38 to accurately locate the position of the storage tool 20. In this embodiment, the scale 39 of the cross bar 34 is a center scale, and the scales 39 on the first slide bar 37 and the second slide bar 38 are both one-way scales, which facilitates the rapid adjustment of the positions of the first slider 35, the second slider 36, the first slide bar 37 and the second slide bar to ensure that the central axis of the workpiece 201 coincides with the central axis of the material taking mechanism 50.

[0030] Specifically, the first slider 35 is provided with a first handle 351 for locking the first slider 35 and a second handle 352 for locking the first slide bar 37, and the second slider 36 is provided with a third handle 361 for locking the second slider 36 and a fourth handle 362 for locking the second slide bar 38, so as to position the storage tool 20, and when the storage tool 20 of the same specification is replaced with subsequent replenishment, it can be directly placed without readjustment. In this embodiment, the first clamping block 31 and the second clamping block 32 are L-shaped, and the fixing member 211 is provided with a right-angle structure matched with the first clamping block 31 and the second clamping block 32.

[0031] Furthermore, the rapid positioning clamping device provided in this embodiment also includes a lifting mechanism 40. Figure 1 As shown, the lifting mechanism 40 includes a motor 41 fixed to the lower part of the base 10, a screw rod 42 provided on the upper part of the base 10, and a lifting plate 43 connected to the screw rod 42. The output end of the motor 41 is connected to the screw rod 42 in a transmission manner. The lifting plate 43 extends into the lower end of the supporting plate 22 to drive the supporting plate 22 to move up and down. It can be understood that the lifting mechanism 40 drives the supporting plate 22 to move upward to cooperate with the material taking mechanism 50 to adsorb the workpiece 201.

[0032] The rapid positioning and clamping device provided by the present invention places the workpiece 201 in the storage fixture 20, and then positions the storage fixture 20 through the positioning mechanism 30. When replenishing materials, the storage fixture 20 is taken out and replaced, which can realize rapid positioning and clamping of storage fixtures 20 of the same specification with precise positioning, making it convenient for other material-retrieving mechanisms to retrieve the workpiece or prepare for the next process, thereby improving production efficiency and reducing labor costs.
