DETAILED DESCRIPTION

[0022] In the following, the application is further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.

[0023] In the description of the present application, it should be noted that for orientation words, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0025] One of the preferred embodiments of the present application, as shown in Figures 1 to 6 A horizontal extrusion casting machine coaxiality detection device, comprising a detection seat 4, a detection rod 5 and a detection assembly A. It should be noted that since the casting machine of the present application is of horizontal structure, as shown in Figure 1 The injection rod 2 and the feeding cylinder 3 are vertically arranged, and of course the fixed mold plate 1 is also vertically arranged. The detection seat 4 is installed on the fixed mold plate 1, and the detection seat 4 is perpendicular to the injection rod 2 and the feeding cylinder 3 (i.e. the detection seat 4 is horizontally installed), and the detection rod 5 is vertically inserted and installed in the positioning pin hole of the detection seat 4, and the detection assembly A is installed on the detection rod 5.

[0026] It can be understood that when the coaxiality is detected, the detection assembly A is first matched with the corresponding injection rod 2 or the feeding cylinder 3, then the detection rod 5 is rotated to drive the detection assembly A to rotate around the injection rod 2 or the feeding cylinder 3, and then the coaxiality is judged through the measurement data of the detection assembly A, which is simple and convenient.

[0027] It should be noted that, as shown in Figure 1 , the installation of the detection seat 4 is fixed by the T-shaped groove 101 of the mold face of the fixed mold plate 1, and then the key groove 102 of the mold face is used for positioning. That is, after the detection rod 5 is installed by the positioning pin hole in the detection seat 4, the axis of the detection rod 5 is theoretically coincident with the axis of the injection rod 2 and the feeding cylinder 3. Therefore, when detecting, the measurement data fluctuation of the detection assembly A can reflect whether the coaxiality between the injection rod 2 and the feeding cylinder 3 is deviated.

[0028] In this embodiment, as shown in Figure 2 , the detection assembly A includes a dial gauge 6, a sleeve 7 and an adjusting frame 8, the sleeve 7 is sleeved and installed on the lower end of the detection rod 5 through the limiting structure 9, and the dial gauge 6 is installed on the sleeve 7 through the adjusting frame 8.

[0029] It can be understood that when detecting, the dial gauge 6 is first positionally adjusted by the adjusting frame 8 so that the measuring head of the dial gauge 6 is located at a suitable position of the injection rod 2 or the feeding cylinder 3, then the dial gauge 6 is driven to rotate by the detection rod 5, and in this process, the reading (i.e. measurement data) of the dial gauge 6 will fluctuate, and the difference between the maximum value and the minimum value of the dial gauge 6 is the coaxiality value.

[0030] The structure of the limiting structure 9 is not limited in the application, and a specific embodiment is provided below for reference:

[0031] The limiting structure 9 includes an inner cylinder 901 and a plurality of limiting blocks 902, the limiting blocks 902 are slidably arranged in the inner part of the sleeve 7 along the radial direction of the sleeve 7 and are equidistantly distributed, and the inner cylinder 901 is matched with the inner part of the sleeve 7 through threads.

[0032] It can be understood that, as shown in Figure 5As shown, when installing, the inner cylinder 901 can be rotated forwardly, and the inner cylinder 901 will be rotated spirally, that is, the inner cylinder 901 will move upwardly while rotating and abut against the limiting blocks 902, and the part of the limiting blocks 902 matched with the inner cylinder 901 is in a wedge-shaped (inclined surface) structure, so that the wedge-shaped extrusion cooperation between the inner cylinder 901 and the limiting blocks 902 can make all the limiting blocks 902 move synchronously and abut against the outside of the detection rod 5, thereby realizing the quick installation of the sleeve 7. Conversely, when disassembling, the inner cylinder 901 is rotated reversely, so that the inner cylinder 901 moves downwardly and away from the limiting blocks 902, that is, the locking installation of the sleeve 7 is released, and the sleeve 7 can be removed.

[0033] It should be noted that when the above-mentioned limiting structure 9 is adopted, not only can the sleeve 7 be quickly installed and limited, but also the coaxiality between the sleeve 7 and the detection rod 5 after installation can be ensured because all the limiting blocks 902 move synchronously for limiting. Of course, the limiting structure 9 of the sleeve 7 in the present application can also be applied to the coaxiality detection of other components, for example, the coaxiality detection between the motor output shaft and the rotating shaft, and the detection assembly A can be quickly installed and limited by the limiting structure 9 in the sleeve 7; and different diameters of “shafts” can be installed within a certain range.

[0034] Further, the limiting blocks 902 and the sleeve 7 can be connected by an elastic member 10 (for example, a spring). It can be understood that after disassembly, that is, the limiting blocks 902 lose the extrusion of the inner cylinder 901, and then the limiting blocks 902 will move and reset to the inside of the sleeve 7 under the action of the elastic force. The purpose is that the limiting blocks 902 will not move randomly under the action of gravity, which is also to facilitate the next installation of the sleeve 7.

[0035] Further preferably, an elastic block 11 (for example, a rubber block) can be arranged on the side of the limiting block 902 close to the detection rod 5; it can be understood that during installation, the elastic block 11 will be deformed and abut against the outside of the detection rod 5 under the extrusion of the limiting block 902, which can increase the friction between the limiting block 902 and the detection rod 5 and ensure the stability of the sleeve 7 after installation, and the material of the elastic block 11 is soft and will not scratch the surface of the detection rod 5.

[0036] In one embodiment of the present application, as shown in Figure 6 The adjusting frame 8 includes a supporting rod 801, a limiting assembly 802, and a clamping member 803, wherein the supporting rod 801 is installed on the inner cylinder 901, and the supporting rod 801 can also be installed on the sleeve 7; the clamping member 803 is rotatably installed at the end position of the supporting rod 801, and the dial gauge 6 is installed on the clamping member 803.

[0037] It can be understood that the dial gauge 6 can be adjusted in rotation through the clamping piece 803, and the limiting assembly 802 can lock the clamping piece 803 after adjustment, that is, the locking of the dial gauge 6 after adjustment is realized.

[0038] As a further description of the above embodiment, as shown in Figure 6 The limiting assembly 802 includes a limiting screw 8021 and a limiting nut 8022, the limiting screw 8021 is fixedly installed at the end of the supporting rod 801, the clamping piece 803 is movably sleeved outside the limiting screw 8021, that is, the clamping piece 803 can rotate along the limiting screw 8021 or move along the axis of the limiting screw 8021, and the limiting nut 8022 cooperates with the limiting screw 8021.

[0039] It can be understood that after the dial gauge 6 is adjusted in rotation, the limiting nut 8022 is spirally rotated until it abuts against the clamping piece 803, at this time, the clamping piece 803 is limited between the limiting nut 8022 and the supporting rod 801, thereby realizing the locking of the clamping piece 803. Similarly, when the limiting nut 8022 is reversely spirally rotated and moves away from the clamping piece 803, the clamping piece 803 can be adjusted in rotation at this time. And when the limiting nut 8022 is disassembled, the clamping piece 803 can be disassembled from the limiting screw 8021, which is simple and convenient.

[0040] Further, as shown in Figure 6 The clamping piece 803 is preferably in a "U" shape structure, and the shaft sleeve 601 of the dial gauge 6 is inserted into the clamping piece 803. That is, the clamping piece 803 can clamp and fix the dial gauge 6 under the action of its own elastic force under normal circumstances, and the dial gauge 6 can also move up and down in the clamping piece 803 under external force operation, thereby realizing the height adjustment of the dial gauge 6. After adjustment, the clamping piece 803 in the "U" shape structure is converged through the tightening and locking of the limiting nut 8022, thereby realizing the locking installation of the dial gauge 6, and thereby improving the stability during detection.

[0041] The working principle of the utility model is:

[0042] (I) installation of the detection device: as shown in Figure 1 The detection seat 4 is fixed by using the T-shaped groove 101 of the mold surface of the fixed mold plate 1 and a bolt, the detection seat 4 is positioned by using the key groove 102 of the mold surface, and the detection rod 5 is installed by using the positioning pin hole in the detection seat 4; finally, the detection assembly A is installed at the lower end position of the detection rod 5 through the sleeve 7.

[0043] (ii) Adjust the detection head of the dial gauge 6 to the inner wall of the barrel 3 through the adjusting frame 8, rotate the detection rod 5 for one round, observe the degree fluctuation of the dial gauge 6, and the difference between the maximum value and the minimum value of the dial gauge 6 is the coaxiality value.

[0044] (iii) Project the injection rod 2 to a part (for example, 30 cm) of the end face of the barrel 3, place the detection head of the dial gauge 6 to the outer circular surface of the injection rod 2 through the adjusting frame 8, rotate the detection rod 5 for one round, observe the degree fluctuation of the dial gauge 6, and the difference between the maximum value and the minimum value of the dial gauge 6 is the coaxiality value.

[0045] Again detect the injection rod 2: at this time, the injection rod 2 can be placed at the half injection stroke position, place the detection head of the dial gauge 6 to the outer circular surface of the injection rod 2, rotate the detection rod 5 for one round, observe the degree fluctuation of the dial gauge 6, and the difference between the maximum value and the minimum value of the dial gauge 6 is the coaxiality value.

[0046] The above describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above examples, the above examples and descriptions in the specification are only the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
