As shown in fig. 1, a weighing apparatus 1 according to an embodiment of the present invention includes a weighing assembly 11 (see fig. 3) for weighing a workpiece, and a housing 12 having a mounting cavity 121, wherein the weighing assembly 11 is at least partially disposed in the mounting cavity 121. One part of the weighing assembly 11 is used for specific weighing of the mass of the workpiece, and the other part is used for carrying the tool to be weighed. In a specific arrangement, the part for weighing in the weighing component 11 is arranged in the mounting cavity 121, so that direct contact with the outside is avoided, and accurate and reliable weighing is ensured.
As shown in fig. 1 and 2, in order to realize the fixed installation of the weighing module 11 (refer to fig. 3), a supporting member 14 for installing and fixing the weighing module 11 is arranged in the installation cavity 121, and the supporting member 14 is fixedly connected to the inner side wall of the housing 12. The support member 14 may be connected to the inner side wall of the housing 12 by a screw-type fastener, or may be integrally formed with the housing 12. In the actual fixed installation, since the weighing assembly 11 is installed on the supporting member 14 by a screw-type fastener, there is a gap in assembly, so that there is a risk that the weighing assembly 11 swings in the first direction (the direction perpendicular to the inner side wall of the housing 12 in the use state) after being fixed. And the weighing component 11 swings in the first direction, so that the position of the weighing component 11 for placing the workpiece to be weighed is unstable, and further the problems that the workpiece is not accurately taken and placed automatically and the weighing result is inaccurate occur. Therefore, it is adopted that a positioning structure 15 for limiting the oscillation of the weighing assembly 11 in the first direction is provided on the support 14. Like this, the subassembly 11 of weighing can further inject the mounted position of the subassembly 11 of weighing through location structure 15 after fixed mounting, makes the subassembly 11 of weighing can not take place the swing on the first direction, and then has ensured that the position that is used for placing the work piece of treating weighing on the subassembly 11 of weighing can remain stable all the time, and the accuracy of weighing is got and is ensured to the smooth clamp of work piece in the use of being convenient for, reduces the error that weighs the in-process and produce, improves the accuracy of weighing the result.

The second positioning block 152 is detachably connected to the other side of the supporting member 14 by a fastener. In this way, the tightness degree of the connection between the fastener and the supporting member 14 can be adjusted to adjust the tightness degree of the second positioning block 152 pressed on the weighing component 11, so as to ensure that the weighing component 11 can be effectively limited to swing in the first direction.
Specifically, as shown in fig. 1 and 2, a through groove 1512 for forming two positioning protrusions 1511 arranged at intervals is formed on the first positioning block 151, and any one or all of the two positioning protrusions 1511 abuts against the weighing assembly 11 (refer to fig. 3). In this way, the limitation of the installation position of the symmetrical heavy assembly 11 is achieved by the action of holding the weighing assembly 11 between any one of the two positioning protrusions 1511 and the second positioning block 152. Preferably, two positioning protrusions 1511 can simultaneously abut against the weighing component 11, so as to ensure the reliability of the limiting effect.
As shown in fig. 1 and 2, the second positioning block 152 includes a body 1521 and a pressing head 1522 disposed on the body 1521, and the pressing head 1522 abuts against the weighing assembly 11 (see fig. 3). The body 1521 is provided with a through hole for the fastener is arranged in a penetrating manner and is connected with the support piece 14, the body 1521 can enable the pressing head 1522 to abut against the weighing component 11 after being fixedly connected with the support piece 14 through the fastener, and the symmetrical component 11 is extruded to play a role in limiting the installation position.
In order to improve the reliability of clamping, anti-slip members, such as a silica gel pad or a rubber pad, may be disposed on the two positioning protrusions 1511 and the pressing head 1522.
