Description

Technical Field

[0001] The utility model relates to the technical field of weight production, in particular to a positioning tool for producing stainless steel weights. Background Art

[0002] A weight is an object used as a mass standard on a balance, usually a metal block or sheet, which can be used to measure a more precise mass. Some weights with higher precision require the weight blank to be clamped by a positioning tool during the manufacturing process and then processed by manual polishing.

[0003] When clamping the weights, the existing positioning tool for weight production needs to adjust the size of the clamping mechanism through tools such as bolts to ensure that the weights can be clamped during the clamping process. However, the process of adjusting the clamping mechanism is not only very cumbersome, but also increases the labor intensity of the operator. The existing positioning tool for weight production does not have a protective function. After a long period of operation, the operator may mistakenly think that the weights have been clamped when they are not. At this time, once the rotating grinding device contacts the weights, it is easy to cause the weights to fly out and injure the operator, which is very dangerous.

[0004] For example, Chinese patent CN213795967U discloses a positioning tool for weight production that supports weights of different sizes. The size of the weight that can be clamped by the clamping rod can be adjusted by rotating the rotating rod. The whole process does not require adjustment of the clamping mechanism by tools such as bolts. Not only is the process quick and easy to operate, but the labor intensity of the operator is greatly reduced. By providing a protective rod, the protective rod limits the protective door on the outer surface of the storage box where the grinding device is placed when the workpiece is not tightened, so that the protective door cannot be opened, and the operator cannot take out the grinding device. This not only avoids the situation where the weights fly out and injure people, but also achieves the purpose of reminding the staff.

[0005] However, when the device grinds the weight through the grinding device after clamping the weight, the weight is vibrated and the reset spring is squeezed, thereby causing the weight to shake during the grinding process, affecting the weight processing accuracy.

[0006] For this reason, we urgently need to provide a positioning tool for stainless steel weight production. Utility Model Content

[0012] Preferably, one end of the connecting rod away from the motor is fixedly mounted on the inner ring of the bearing, and the bearing supports the connecting rod.

[0013] Preferably, the connecting rod is provided with external threads in opposite directions on the left and right sides, and the connecting rod passes through the interior of the left and right moving blocks and is threadedly connected to the moving blocks. The connecting rod is driven to rotate by starting the motor. When the connecting rod is threadedly connected to the left and right moving blocks, the left and right moving blocks drive the clamps to move in opposite directions to clamp the weights on the top of the placement table.
