Description

TECHNICAL FIELD

[0001] The utility model relates to a film box taking and placing bracket with calibration function for mechanical arm belongs to the field of ray flaw detection. BACKGROUND

[0002] The film box is about 460mm*15mm*380mm in length, width and height, needs to keep vertical state to facilitate the grabbing of the mechanical arm.

[0003] The consistency of the storage position of the film box on the bracket each time influences the working efficiency of the mechanical arm and the probability of accidental collision damage. When grabbing the film box, the mechanical arm requires that the position of the box body should be as accurate as possible to facilitate accurate grabbing. When placing the film box, the mechanical arm requires that the position of the box body should have sufficient margin to cope with possible positioning deviation. When taking and placing using the same bracket, the two requirements are contradictory. The taking and placing bracket should also have a certain rigidity to ensure that it can still maintain sufficient accuracy after being subjected to normal mechanical load and possible accidental load during use, and to ensure that the stored articles are not greatly deviated.

[0004] The conventional design can adopt the guiding groove design of wide upper part and narrow lower part, and the guiding groove guides the grabbing position when the article is placed. The above taking and placing requirements are met. However, the upper part of the guiding groove is not supported, the upper half of the article is easy to swing, and it is easy to be stuck after wear, and the replacement and installation are difficult. It is not suitable for long-term use.

[0005] In the long-term use process, the stress point of the sliding rail type guide is single, and the stress point will inevitably be worn. After wear, the friction between the film box and the guiding groove increases, which leads to accelerated wear until the film box is stuck during taking and placing. TECHNICAL SOLUTION

[0006] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and provide a film box taking and placing bracket with calibration function for mechanical arm.

[0007] The technical solution of the utility model is: a film box taking and placing bracket with calibration function for mechanical arm, comprising: a front plate, a bottom plate, a side plate, a metal roller, a connecting piece, a movable piece, a rear plate, wherein:

[0008] The front plate and the rear plate are oppositely installed on the two edges of the bottom plate, and the two side plates are respectively installed on the remaining two edges of the bottom plate, and together constitute the main structure of the film box taking and placing bracket;

[0009] The inner wall of each side plate is divided into 2xN parts along the gravity direction, rectangular through holes are arranged on the odd parts to place the movable piece, and three metal rollers are uniformly installed on each odd part and even part along the gravity direction;

[0010] The guide grooves of one odd number and one even number of film boxes are adjacent, and a connecting piece is horizontally arranged between the first row and the second row and between the second row and the third row of each guide groove on the outer wall of the side plate.

[0011] Preferably, a hand hole is arranged at the upper middle part of the front plate and the rear plate for facilitating the carrying of the assembled device.

[0012] Preferably, four through holes and four counterbores are arranged at the middle part of the bottom plate for connecting with external structures.

[0013] Preferably, the main body structure of the film box taking and placing bracket is made of an aluminum alloy plate.

[0014] Preferably, the thickness of the movable piece is less than the thickness of the side plate by 2mm±0.06mm, and the width of the movable piece is less than the width of the opening of the side plate by 5mm±0.1mm, so that the movable piece has a certain moving space.

[0015] Compared with the prior art, the device has the following advantages:

[0016] (1) The bracket of the device uses metal rollers for calibration guidance and storage position division. When the film box is slightly offset, the metal roller can provide a force from the center of the circle to the contact point. The force direction will always point to the film box storage position and disappear after guiding the film box to the accurate position, thereby improving the stability of taking and placing.

[0017] (2) The main body of the bracket of the device is made of 12mm thick aluminum alloy, which ensures that the overall rigidity is sufficient to withstand general external forces caused by human or accidental reasons. At the same time, the overall weight can be carried by a single person, which is convenient for adjustment and installation.

[0018] (3) Compared with the sliding rail type guidance, the roller type guidance has the advantages that the stress points of the rollers are not fixed, and when one point is worn, the friction at this point increases more easily than other points, which can cause the rollers to rotate, so that the overall wear degree of the rollers tends to be average, the friction is smaller and less likely to be stuck, and the service life is greatly increased.
