Description

Technical Field

[0001] The utility model relates to the technical field of weight detection of automobile parts, and specifically relates to a weighing mechanism. Background Technique

[0002] After the existing automobile parts are manufactured, in order to conduct inspections, it is necessary to perform weighing operations on the automobile parts. If their weight is within the designed range, they are qualified parts; otherwise, they are unqualified parts. The existing weighing method is to directly fix the bearing seat on the balance. The balance is a precision measuring instrument. When placing and removing parts, it is easy to cause overpressure and additional force on the balance, resulting in a serious shortening of the service life of the balance. Therefore, there is an urgent need to develop a floating weighing mechanism that can separate and attach the balance and the bearing seat, thereby reducing the attachment pressure on the balance and extending the service life of the balance. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a weighing mechanism, which can separate and attach the balance and the bearing seat according to requirements, reduces the attachment time of the balance, and extends the service life of the balance.

[0004] A weighing mechanism, characterized in that it includes: A balance assembly, which includes a balance measuring body and a balance display; A mounting seat, which includes a supporting plate and two side vertical plates; A misalignment cylinder; A floating guide member, which includes a horizontal connecting plate, two guide rods, and a horizontal supporting seat; And a bearing seat, which includes a placement cavity for placing parts on the upper part; The balance measuring body is fixedly installed at the center position of the supporting plate, and the measuring part of the balance measuring body protrudes upward. A misalignment cylinder is fixedly installed at the bottom of the supporting plate. The lower piston end of the misalignment cylinder is fixedly connected to the horizontal connecting plate. The two ends of the length direction of the horizontal connecting plate are respectively fixedly connected with upwardly protruding guide rods. The two ends of the horizontal supporting seat are respectively fixedly connected to the tops of the corresponding guide rods. In the unweighed state, the bearing seat is embedded in the center position of the upper surface of the horizontal supporting seat, and the horizontal supporting seat is higher than the measuring part. A through avoidance hole is provided at the center of the upper surface of the horizontal supporting seat, and the through avoidance hole is set according to the shape of the measuring part. In the weighed state, the horizontal supporting seat is lower than the measuring part, and the bottom of the bearing seat is supported on the upper surface of the measuring part.

[0005] It is further characterized in that: The floating guide member further includes two groups of linear bearings, and the linear bearings are fixedly installed in the through holes of the corresponding side regions of the supporting plate. The guide rods pass through the linear bearings, which makes the linear lifting of the guide rods stable and reliable; The floating guide also includes two sets of springs, each set of springs being fitted onto the upper region of the guide rod corresponding to the support plate. When the horizontal support is in a low position, the springs are used to provide elastic support to the horizontal support. The upper surface of the horizontal support seat is provided with a contoured positioning cavity corresponding to the bottom of the support seat, which ensures that the support seat is reliably placed in the horizontal support seat. It also includes a base plate on which mounting bases and a balance display are fixedly mounted, making the entire weighing mechanism easy to move as a whole.

[0006] With the structure of this utility model, in the non-weighing state, the misalignment cylinder drives the horizontal support seat to rise, making the horizontal support seat higher than the measuring part. The bearing seat is located inside the horizontal support seat and is detached from the measuring part. This state facilitates the removal and placement of the part to be measured from behind the bearing seat. In the weighing state, the lower piston of the misalignment cylinder moves downward, the horizontal support seat is lower than the measuring part, and the bearing seat is fully supported by the measuring part. The reading is then displayed on the balance display. Under the action of the misalignment cylinder, when removing or placing parts, it ensures that the bearing seat does not contact the measuring part of the balance body. It can separate and press the balance and the bearing seat as needed, reducing the pressing time of the balance and extending the service life of the balance. Attached Figure Description
