Description

Tool positioning clamp

Technical Field

The invention relates to a clamp, in particular to a tool positioning clamp.

Background

In the industrial automatic production process, because the technological requirement, need to fix a position and press from both sides tight to the product, and fix a position and press from both sides tight mechanism called anchor clamps, and the appearance difference of product also directly influences the design of anchor clamps, because the cell-phone center requires very harsh to the outward appearance, need consider to the protection of outward appearance simultaneously, still guarantee to have enough clamping-force can not appear the indentation to the product.

The clamp of the traditional mobile phone middle frame mostly uses a cylinder to carry out automatic clamping, but the cost of the similar clamp is higher, the clamp is generally applied to large-scale assembly line production and manufacturing, and compared with the detection or small-scale application range, the clamp more suitable for manual operation can be more economical, however, for the clamp of the similar mobile phone middle frame product, the appearance of the product is easy to damage in the manual operation process of the conventional rigid clamp, and the problem that the clamping force is insufficient when the flexible clamp is used for carrying out manual clamping on the mobile phone middle frame is easy to generate, so that the products such as the mobile phone middle frame and the like fall off from the clamp, and the traditional mobile phone middle frame clamp can only clamp one or a single mobile phone middle frame, cannot clamp the mobile phone middle frames with the front and the back or two different processes at the same time, needs a plurality of clamps to realize the functions, the detection or the production efficiency is reduced, and the equipment cost is increased, therefore, the clamp capable of adjusting the clamping force and clamping the front and the back or the two different processes at the same time needs to be provided to solve the problems.

For example, in a chinese patent publication No. CN111942648A, a positioning jig for a mobile phone is disclosed, in which a side plate is dragged by a hand, a long plate portion and a short plate portion move simultaneously and are away from a supporting plate, and at this time, a first return assembly, a second return assembly, a third return assembly, and a fourth return assembly are compressed simultaneously. Place the cell-phone behind the layer board, the hand loosens, and first return subassembly, second return subassembly promote long board portion and remove towards the cell-phone, and third return subassembly, fourth return subassembly promote short board portion and remove towards the cell-phone, realize the location centre gripping to the cell-phone, but this scheme can't satisfy the regulation to clamping-force, can't adjust according to the product difference to the centre gripping effect, and adaptability is little.

Chinese utility model patent like publication No. CN213532193U, it discloses a positioning jig is used in processing of cell-phone shell, this scheme utilizes four mount pads, the gag lever post, the fixed block, a spring, the threaded rod, the clamp plate, the spacing ring, the cooperation of support and loading board, be convenient for carry out avris and direction of height's spacing to the cell-phone shell of different models, the use universality of anchor clamps has been improved, but this scheme carries out the centre gripping formula at the cell-phone shell and needs artifical wrench movement handle could place between loading board and the clamp plate with the cell-phone shell, it is very inconvenient, and loading board and clamp plate cause the crush injury through the cooperation of handle turning threaded rod easily to the cell-phone shell, cause the damage of product.

In conclusion, the invention not only realizes the function of adjusting the clamping force, but also reduces the cost and meets the effect of flexible clamping.

One preferred scheme is that the two carrier block stations are provided with first copying carrier blocks.

In conclusion, the mobile phone middle frame detection device can meet the requirements of processing or detecting the mobile phone middle frames on the same side in two groups of same working procedures by arranging the same copying carrying blocks, and the space utilization rate is increased.

According to a preferable scheme, a second copying carrying block and a third copying carrying block are respectively arranged on the two carrying block stations.

In conclusion, the invention can meet the requirements of processing or detecting the front and back mobile phone middle frames in two different procedures or the same procedure by arranging the two copying carrying blocks, thereby improving the production or detection efficiency.

One preferred scheme is that both sides of the bottom of the carrier plate are provided with stainless steel sheets.

In conclusion, the arrangement of the stainless steel sheet can reduce the abrasion between the carrier plate and the carrier or the belt, and the service life can be prolonged.

One preferred scheme is that the bottom of the carrier plate is provided with a magnetic attraction piece, and the magnetic attraction piece is matched with a magnet device on the assembly line carrier.

In summary, the arrangement of the magnetic attraction pieces can enable the invention to generate attraction on the carrier, so that the clamp is more stable and is not easy to fall off.

One preferred scheme is that two positioning pin holes which are centrosymmetric are arranged at the bottom of the carrier plate, and the positioning pin holes are matched with positioning pins on the assembly line carrier.

In conclusion, the positioning pin hole is matched with the positioning pin on the assembly line carrier, so that the invention is more stable, the shaking of the clamp is reduced, and the processing or detection effect on the mobile phone middle frame is improved.
