New description: [New technical field] This creation is about a strain sensing device, especially for a strain •rvof %. [Prior Art] As shown in the first figure, in the injection molding machine, in order to control the clamping force of the two templates j, 2 to a predetermined value, there is a need to install a strain sensor, and the strain ring 3 is therein. A common strain sensor that senses its strain by sandwiching a tie bar (Tiebar) 4, thereby deriving the clamping force of the templates 〖, 2. One of the existing fixing methods of the strain ring is that a screw hole extending in a tangential direction is respectively disposed at two joints of the two curved blocks, and the two curved blocks are tightened by two screws to be lost in the system. Rod; since the strain ring is in a relatively short time, two screws need to be screwed in sequence, so it is not convenient to process. Another type of strain ring is fixed by providing a quick release at one of the joints of the two curved blocks to improve the ease of assembly and disassembly, but the disadvantage is that the strain ring cannot be fine-tuned: in addition, there is occasional tolerance from the outer diameter of the tie rod and It is difficult to form a true circle. This strain % can't be tightly tied to the tie rod, which leads to the accuracy of the sensed strain. Therefore, how to find a compromise between installation convenience and precision' Self-study in the direction of the industry. [New Content] The main purpose of this creation is a convenient strain loop. The present invention provides a strain ring that can be tightly clamped to the tie rod and installed in order to achieve the above and other purposes. The present invention provides a strain ring that is measured by the strain amount of the machine that is injected into the 3 4 M442500 type machine, and the strain ring includes a strain ring. a first one, a second arc, at least one strain gauge and a tapered screw, the first arc has a first connecting end and a 'first connecting end', and the second arc has a second a first connecting end and a first connecting end, the first pivoting end is dragged to the first one of the first connecting ends, and the first and second connecting ends respectively have first and second threaded tapered holes, when the first When the second threaded taper hole is coaxial, the second thread taper hole is located on the extended tapered surface of the first thread taper hole. In addition, the strain gauge is disposed on an inner surface of at least one of the first and second arcs, and the tapered screw is configured to simultaneously lock the first and second threaded tapered holes to tightly clamp the strain ring to the system. The rod and the strain gauge are attached to the surface of the tie rod. Because the strain ring of this creation is pivoted on one side, the other side uses the cooperation of the taper hole and the taper screw, so the installation can be completed in a shorter time (compared to the strain ring using two screws) At the same time, it can gradually adjust the force of the jacket on the cup to avoid the measurement error caused by the tie making tolerance and thus meet the needs of the user. [Embodiment] Hereinafter, the structure of the present creation and the intended use of the text will be described by a preferred embodiment to limit the fan peak to be protected by the present creation. Call > Khao Di - to five maps. In a preferred embodiment of the present invention, a strain ring 1G for cooling the injection machine tie rod 4 as shown in the first figure includes - an arc 颚 2 〇, a second arc 颚 30, and a second strain gauge. 40 and a tapered screw 50. 4 (4) 20 has a first holding end 21 and a first connecting end 22, . The hoarding end 22 is formed with a --thread taper hole 23' coaxial with the strain ring 1 (). "Threaded taper hole" herein means a tapered hole having an internal thread. The second arc 30 has a second docking end 31 and a second connecting end 32. The second pivoting end 31 is pivotally connected to the first pivoting end. The manner in which the end portions 2b are pivotally connected to each other includes the first and second shafts 26 and 30 respectively for opening the shaft 27 or the rivet, and the first and second tantalum ends 2b 31 The hinge or other suitable manner is as follows: at the third connecting end 32, the taper of the two 33' sides and the second spiral peaks 23, 33 coaxial with the strain ring 1〇 are the same and the taper is The figure is limited to the limit, and when the first and second threaded taper holes 23, %^-the second and second arcs 20, 3G are pivoted relative to each other, the second = tapered hole 33 Just on the extended tapered surface s of the first-thread taper hole 23, as shown in FIG. 5, the two strain gauges 40 are respectively disposed on the inner surfaces 25, 35 of the first and second arcs 20, 30, respectively. When the strain ring 1 is sleeved on the tie rod 4, the strain gauge 4 is used to measure the strain amount of the tie rod 4, and the two strain gauges 4G can approximately protrude from the inner surface 25, 35 to obtain a more accurate 1^'彳 result; It is worth noting that this creation can also be set only There is a single strain gauge 40. At this time, the strain gauge 40 is only located on the inner surfaces 25, 35 of one of the first and second arcs 2〇, 3〇; since the type and setting of the strain gauge belong to the scope of conventional skill This will not be repeated here. The tapered screw 5 has the same taper as the first and second threaded tapered holes 23, y for simultaneously locking the first and second threaded tapered holes 23, 33. In addition, the strain ring 10 of the present invention has an inner diameter that is not larger than the outer control of the tie rod 4, and the inner diameter is defined as the first and second threaded taper holes 23, 33 when coaxial, first and first. The diameter of the perforation of the arc 20, 30 is preferably smaller than the outer diameter of the tie rod 4, for example, when the outer diameter of the tie rod 4 is 60 mm, the inside of the strain ring can be made 1 The diameter is designed to be 59 8mm or other suitable value, 5 M442500 allows the strain ring 10 to tightly tie the tie rod 4 and allow the tie rod 4 to have some manufacturing tolerances' and allow the strain gauge 40 to fit snugly against the surface of the tie rod 4 for accurate The variable is measured. When the strain ring 10 is installed, the first and second arcs 20, 30 are first fastened to the tie rod 4 as shown in the sixth figure. Since the inner diameter of the strain ring 10 is slightly smaller than the outer diameter of the tie rod 4, The first and second threaded tapered holes 23, 33 are not coaxial; after that, as shown in the seventh figure, the curved screw 50 is inserted into the first and second threaded tapered holes 23, 33 'the opposite two of the curved screws 50 The sides are respectively pressed against the first and second threaded taper holes 23, 33, and then, as shown in the eighth figure, the screw-locking curved screws 5 are urged to continue deep into the first and second threaded tapered holes 23, 33 until When the predetermined torque value is reached or the screwing cannot be continued, the strain ring 10 is tightly sleeved on the tie rod 4; it is worth mentioning that even if the inner diameter of the strain ring 10 is slightly smaller than the outer diameter of the tie rod 4, even The curved screw 50 has reached the required torque, and the first and second threaded tapered holes 23, 33 may not be coaxial and have a slight deviation (not shown), but the first and second arcs 20, 30 The inner surface 25, 35 and the strain gauge 4〇 can still be in close contact with the outer surface of the cup 4 at this time, without hindering the strain gauge 4〇 measuring the quasi-stroke of the strainer 4 And because the user only needs to screw a conical screw 5〇, the time required for assembly can be shortened, and the user's expectation can be achieved in consideration of the convenience of operation and the accuracy of measurement. The above description is only a preferred embodiment of the present invention, but the structure can still be appropriately changed, for example, the first and second connecting ends 22, 32 and the first and second arcs 20, 30 The relative thickness and shape of the space can be changed, and the axial directions of the first, the first screw, and the holes 23, 33 can also be changed to be slightly skewed to the axial direction of the strain ring, so that the spirit of the case is not exceeded. The structural modification made should still belong to the category of 6 M442500 intended to be protected.
