The size of the whole clamping mechanism can be adjusted by the length of the screw rod in the threaded hole, so that the clamping mechanism is suitable for refrigerator bottom plates with different sizes. The refrigerator bottom plate is clamped and fixed in the clamping mechanism under the restoring action of the spring.

Furthermore, one side of the telescopic clamping arm, which is in contact with the refrigerator bottom plate, is provided with a groove, and the edge of the refrigerator bottom plate is clamped into the groove.

Further, the upper sides and the lower sides of the four corners of the clamping mechanism are provided with fan-shaped fixing pieces. The stationary blade of corner can fix four angles of refrigerator bottom plate better, strengthens the stability of the in-process refrigerator bottom plate of polishing.

Furthermore, one of the rotating shafts penetrates through two sides of the supporting frame and is connected with a power mechanism which drives the clamping mechanism to overturn, and the power mechanism is arranged on the supporting frame.

Furthermore, power unit includes gear, second cylinder and sliding connection rack on the support frame, and the second cylinder is installed on the support frame and is connected with the one end of rack, and the gear is with the coaxial fixed connection of pivot that runs through the support frame, gear and rack toothing. The rack slides in the telescopic process of the second cylinder, the rack slides to drive the gear to rotate, and the gear rotates to drive the clamping mechanism to rotate, so that the refrigerator bottom plate on the clamping mechanism is overturned.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the grinding machine comprises a support frame 1, a rack 2, a gear 3, a grinding head 4, a motor 5, a first air cylinder 6, an upper frame 7, a support plate 8, a second air cylinder 9, a clamping mechanism 10, a rotating shaft 11, a spring 12, a fixing sheet 13, a fixed length rod 14 and a screw rod 15.

Example 1, substantially as shown in figure 1: the utility model provides a refrigerator bottom plate equipment of polishing, includes frame 7, undercarriage and three interval and establishes and be used for the fixture 10 of fixed refrigerator bottom plate, and frame 7 is connected directly over the undercarriage through backup pad 8. The lower rack comprises two parallel supporting frames 1, the upper rack 7 is connected with three polishing mechanisms through a first cylinder 6 which longitudinally stretches out and draws back, each polishing mechanism comprises a motor 5 and a polishing head 4 positioned below the motor 5, the motor 5 is connected with the stretching end of the first cylinder 6, and the polishing heads 4 are fixedly connected with output shafts of the motors 5.

The grinding mechanism is located directly above the clamping mechanism 10. Referring to fig. 2 and 3, the clamping mechanism 10 is formed by connecting four telescopic clamp arms end to end, and fan-shaped fixing pieces 13 are arranged on the upper side and the lower side of four corners of the clamping mechanism 10; the middle parts of the two telescopic clamping arms are fixedly connected with a rotating shaft 11, each telescopic clamping arm comprises a spring 12 and fixed long rods 14 connected to two ends of the spring 12, a groove is formed in one side, in contact with a refrigerator bottom plate, of each fixed long rod 14 of each telescopic clamping arm, and the edge of the refrigerator bottom plate is clamped into the groove; fixture 10 rotates through two pivot 11 and connects between two support frames 1, one of them pivot 11 runs through the both sides of support frame 1 and is connected with the power unit that drives fixture 10 upset, and power unit includes gear 3, second cylinder 9 and sliding connection rack 2 on support frame 1, and second cylinder 9 is installed on support frame 1 and is connected with the one end of rack 2, gear 3 and the coaxial fixed connection of pivot 11 that runs through support frame 1, gear 3 and rack 2 meshing.
