DETAILED DESCRIPTION

[0028] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0029] In the description of the present application, it should be noted that for orientation words, such as the terms “center”, “transverse”, “longitudinal”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “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 cannot be understood as indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0030] It should be noted that the terms "first", "second" and the like in the description and claims of the application are used for distinguishing between similar objects and are not necessarily used to describe a particular sequential or chronological order.

[0031] One of the preferred embodiments of the present application is shown in Figures 1 to 11 A movable part testing system of die casting machine, comprising a hinged seat 4, a pin shaft 7, a pair of limiting members 9, a driving member and a transmission assembly 8, wherein the hinged seat 4 is installed in the testing system, the hinged seat 4 comprises a seat body 401 and a pair of ear plates 402 connected to the seat body 401, the end of the connecting rod assembly 1 to be detected and installed is matched between the two ear plates 402, the pin shaft 7 is penetrated through the ear plates 402 and the end position of the connecting rod assembly 1, the two limiting members 9 are rotationally arranged at the outer side position of the two ear plates 402, the driving member is installed in the seat body 401, the transmission assembly 8 is also arranged in the seat body 401 and the input end is matched and connected with the driving member, and the output end of the transmission assembly 8 is connected with the limiting members 9.

[0032] It can be understood that, in the initial state, as shown in Figure 9 The limiting members 9 are retracted and close to the position of the seat body 401, that is, at this time the limiting members 9 do not interfere with the insertion and removal of the pin shaft 7. When the pin shaft 7 needs to be locked after installation, the driving member is operated and the transmission assembly 8 drives the two limiting members 9 to rotate relatively, and the two limiting members 9 gradually approach and abut against the pin shaft 7 in the process of rotation, that is, the limiting members 9 also have a centering effect on the pin shaft 7 in the process of rotation, and then the two limiting members 9 abut against and are clamped into the limiting grooves 14 at both ends of the pin shaft 7, so that the axial and circumferential locking of the pin shaft 7 is achieved, and the connection and installation of the end of the connecting rod assembly 1 are completed. Similarly, conversely, when the end of the connecting rod assembly 1 is disassembled, that is, the pin shaft 7 needs to be unlocked, at this time the two limiting members 9 are rotated (that is, reversed) away from the limiting grooves 14 by the cooperation of the driving member and the transmission assembly 8, so that the limiting members 9 are rotated to the initial state.

[0033] As can be seen, when the connecting rod assembly 1 is installed and tested, only the single driving member needs to be operated, without the need for the complicated operations such as installing the clamping plate 5 and tightening the bolts as in the prior art, greatly simplifying the installation process and significantly improving the testing efficiency. Moreover, when the limiting members 9 are unlocked and disassembled from the pin shaft 7, they can be retracted beside the seat body 401, so that on the one hand they do not occupy too much space, and on the other hand they do not interfere with the disassembly of the pin shaft 7, and such a design can avoid the confusion and loss caused by the storage of the limiting members 9, greatly improving the convenience.

[0034] Further description of the above embodiment: as shown in Figures 5 to 7As shown, the driving component is a lead screw 12, which is vertically and rotatably mounted inside the base 401. The transmission assembly 8 includes a transmission block 801, a pair of transmission rods 802, a pair of transmission blocks 803, and a pair of transmission rods 804. The transmission block 801 is vertically and slidably disposed inside the base 401 and threadedly engaged with the lead screw 12. The transmission blocks 803 are horizontally and slidably disposed on both sides of the base 401. The two ends of the transmission rods 802 are rotatably connected to the transmission blocks 801 and the corresponding transmission blocks 803, respectively. The two ends of the transmission rods 804 are hinged to the corresponding transmission blocks 803 and the limiting member 9, respectively.

[0035] To facilitate a more detailed understanding of the locking and unlocking process of the aforementioned pin 7, its working principle is described below: like Figure 4 As shown, at this time, the limiting member 9 is in the locked state of the pin 7, the limiting member 9 cooperates with the limiting groove 14, and the limiting member 9 and the seat 401 are in a perpendicular state. When unlocking the pin 7, rotate the lead screw 12 in the forward direction, as shown. Figure 6 As shown, lead screw 12 acts on transmission block 801 to move downward, transmission block 801 acts on two transmission rods 802, and transmission rods 802 act on two transmission blocks 803 to move horizontally away from each other. Figure 7 As shown, the two limiting members 9 will rotate relative to each other away from the limiting groove 14, until they rotate to a state parallel to the seat 401, and then the limiting members 9 are in a retracted state, as shown. Figure 9 As shown, the pin 7 can then be pulled out and disassembled to facilitate the installation and testing of the next set of connecting rod assembly 1. Conversely, when locking the pin 7, the lead screw 12 is rotated in the opposite direction, causing the limiting member 9 to rotate relative to and approach the limiting groove 14 of the pin 7 until it engages with the limiting groove 14 of the pin 7.

[0036] It should be noted that the pivot of the limiting member 9 is in a vertical position, and the lead screw 12 that drives it is also in a vertical position. If the lead screw 12 is to drive the two limiting members 9 to rotate simultaneously, the general design is to use gears, sprockets and chains, or belts and pulleys to drive the limiting members 9 to rotate. However, the above-mentioned methods have problems such as complex structure and large space occupation. For example, when using gears, the base 401 needs to have sufficient thickness to provide installation space for the gears; when using chain drives, multiple chains and sprockets are required, which is a complex structure; in addition, a locking structure is required to lock the lead screw 12 or the limiting member 9 after adjustment, because the above transmission methods do not have a self-locking function, that is, the limiting member 9 is in a free state after rotation, and therefore cannot play a role in locking the pin 7 axially; also, the limiting member 9 is only limited by the pivot at the end, and the stability after locking the pin 7 is not good enough.

[0037] The application adopts the design of the above-mentioned transmission block one 801, the pair of transmission rods one 802, the pair of transmission block two 803 and the pair of transmission rods two 804, as shown in Figure 5 First, these components are installed and arranged in the vertical direction of the seat body 401 in space, and are uniformly located in the seat body 401, which can fully utilize the space in the seat body 401. Moreover, the screw rod 12 and the transmission block one 801 have a self-locking effect, that is, after the screw rod 12 stops rotating, the transmission block one 801 will also remain in the current position under the action of the thread, thereby providing a guarantee for the stable locking of the limiting piece 9 to the pin shaft 7. In addition, as shown in Figure 4 When the limiting piece 9 is in the locked state of the pin shaft 7, the transmission rod two 804 supports and limits the middle position of the limiting piece 9 at this time, which can further enhance the stability of the limiting piece 9 after locking the pin shaft 7 and improve the overall strength.

[0038] Based on the above-mentioned embodiment, there may be a problem that since the limiting piece 9 is rotated to cooperate with the limiting groove 14, and the limiting piece 9 has a certain thickness, the positions of the end portions of the limiting piece 9 and the limiting groove 14 are also in a clearance fit state when they cooperate, which is also based on the fact that the limiting groove 14 needs to provide a space for the rotation of the limiting piece 9, as shown in Figure 4 Therefore, the pin shaft 7 cannot be well limited in the left and right radial directions.

[0039] Therefore, in order to solve the above-mentioned technical problem, an extension part 16 is arranged at the end portion of the limiting piece 9, and an extension groove 17 is arranged at the end portion of the limiting groove 14. It can be understood that when the limiting piece 9 and the limiting groove 14 are connected and cooperated, the extension part 16 and the extension groove 17 form an interference fit at this time, that is, the thickness of the extension part 16 is smaller than the thickness of the limiting piece 9, and the extension part 16 will be forced to cooperate with the extension groove 17 when rotating, which can limit the pin shaft 7 in the left and right radial directions, and the limiting piece 9 can stably limit the pin shaft 7 in the up and down directions and the front and back directions, thereby realizing the omnidirectional limiting of the pin shaft 7 and ensuring the stability of the connecting rod assembly 1 during testing and installation.

[0040] In one embodiment of the application, as shown in Figure 10As shown, the cross-sectional area of the middle part of the limiting piece 9 is smaller than the cross-sectional area of the end part of the limiting piece 9. It should be understood that when the limiting piece 9 rotates close to the pin shaft 7, the middle part of the limiting piece 9 will first contact the pin shaft 7, and at this time, it is necessary to ensure that the limiting groove 14 on the pin shaft 7 completely corresponds to the limiting piece 9, otherwise it will cause the problem of interference when the limiting piece 9 rotates. By "thinning" the middle part of the limiting piece 9, that is, the caliber of the limiting groove 14 is larger than the middle part of the limiting piece 9, so that during the process of the limiting piece 9 rotating close to the pin shaft 7, even if the limiting groove 14 and the limiting piece 9 do not completely correspond, the thinner part of the middle part of the limiting piece 9 can also smoothly enter the opening range of the limiting groove 14, improving the convenience of installation. With the continuous rotation of the limiting piece 9 close to the limiting groove 14, under the extrusion cooperation of the side inclined surface of the limiting piece 9, it can play a correcting role on the pin shaft 7, that is, the pin shaft 7 will rotate circumferentially and make the limiting groove 14 correspond to the limiting piece 9.

[0041] When the connecting rod assembly 1 is installed and tested, it will also encounter such a problem: as shown in Figure 2 and Figure 4 , when the end part of the connecting rod assembly 1 cooperates with the ear plate 402, at this time the end part of the connecting rod assembly 1 needs to be held by one hand of the worker, and then the other hand inserts the pin shaft 7, and the connecting rod assembly 1 has a certain weight. The worker will be more tired during this process, which will affect the accuracy and efficiency of the subsequent insertion of the pin shaft 7.

[0042] In order to solve the above problems, as shown in Figure 5 , Figure 6 and Figure 8 , the die-casting machine movable part test system further comprises a transmission device 13 and a supporting plate 15, the supporting plate 15 is rotatably installed at the bottom end of the ear plate 402, and the transmission device 13 is arranged in the seat body 401 and connected with the lead screw 12 at the input end. The output end of the transmission device 13 is connected with the supporting plate 15.

[0043] It can be understood that when the pin shaft 7 is unlocked, the lead screw 12 can drive the supporting plate 15 to rotate close to the bottom end position of the end part of the connecting rod assembly 1 through the transmission device 13, so as to support the end part of the connecting rod assembly 1 and improve the convenience of installation. Similarly, when the pin shaft 7 is locked, the lead screw 12 can drive the supporting plate 15 to rotate and be attached and stored at the bottom end of the ear plate 402 through the transmission device 13, so as to realize the storage of the supporting plate 15 and prevent the supporting plate 15 from interfering with the rotation of the connecting rod assembly 1 during testing.

[0044] As a further description of the above embodiment: the transmission 13 comprises a worm gear 1301 and a worm 1302, the worm gear 1301 is installed on the rotating shaft of the supporting plate 15, and the worm 1302 is connected with the screw rod 12, that is, the supporting plate 15 rotates under the cooperation of the worm 1302 and the worm gear 1301. It should be understood that there is self-locking between the worm gear 1301 and the worm 1302, so that when the supporting plate 15 supports the end of the linkage assembly 1, the stability of the position of the supporting plate 15 can be ensured, and the supporting plate 15 will not rotate by itself due to the weight of the linkage assembly 1 and other factors, thereby ensuring the reliability of the support of the linkage assembly 1.

[0045] Further, the supporting plate 15 is preferably provided with a pair of corresponding supporting plates 402, and of course the worm gear 1301 is also provided with a pair of corresponding supporting plates 402 located on both sides of the worm 1302. It can be understood that when the pin shaft 7 is not locked, as shown in Figure 9 , the two supporting plates 15 are horizontally located on the same straight line, that is, the two supporting plates 15 are better supported at the lower end of the gap between the two supporting plates 402, forming a stable support surface to provide reliable support for the end of the linkage assembly 1. When the pin shaft 7 is locked, the two supporting plates 15 rotate one hundred and eighty degrees under the cooperation of the worm gear 1301 and the worm 1302, that is, they are attached and stored at the bottom end of the supporting plate 402, and at this time the projection of the supporting plate 15 in the vertical direction completely coincides with the projection of the supporting plate 402 in the vertical direction, thereby saving the occupied space to the greatest extent during storage. Compared with the case where one supporting plate 15 is used, the other pair of supporting plates 15 can more evenly share the weight of the end of the linkage assembly 1, further improving the stability during support.

[0046] It should be noted that, as shown in Figure 1 , the linkage assembly 1 has three ends (i.e. left, right and bottom), and during specific installation and testing, the hinge seat 4 at the bottom end of the linkage assembly 1 can support the linkage assembly 1 itself, so the hinge seat 4 at the bottom end can not be provided with a supporting plate 15 and the like according to the actual situation, and only the hinge seats 4 at the left and right ends need to be provided with a supporting plate 15 and the like.

[0047] Further, a limiting assembly (not shown) can be provided at the opposite end of the two supporting plates 15. It can be understood that when the two supporting plates 15 are unfolded and supported, the opposite ends of the two supporting plates 15 can be limited by the limiting assembly, because the support of the supporting plate 15 is completely supported by the rotating shaft at the rotating end, so that in the case that the rotating shaft is damaged due to excessive stress during support, the limiting assembly can also provide a supporting and limiting force to the supporting end of the supporting plate 15, thereby enhancing the overall supporting strength of the supporting plate 15 and prolonging the service life.

[0048] The structure of the limiting assembly is not specifically limited in the present application, and two specific embodiments are provided below for reference. Structure one: the limiting assembly is a magnetic assembly, for example, a magnet is arranged at the corresponding position of one end of each of the two supporting plates 15, when the supporting plates 15 are unfolded to support, the two magnets attract each other, thereby forming a limit to the supporting end of the supporting plate 15 and enhancing the supporting strength. Structure two: the limiting assembly is a buckle assembly, for example, a buckle and a clamping groove are arranged at the corresponding positions of one end of each of the two supporting plates 15, when the supporting plates 15 are unfolded to support, the buckle is clamped into the clamping groove, thereby forming a stable limit to the supporting end of the supporting plate 15. Of course, both structures can meet the actual needs, and those skilled in the art can select according to the actual situation.

[0049] Further, a driving part flush with the seat body 401 can be arranged at the top end of the lead screw 12, and then the worker can drive the lead screw 12 to rotate by cooperating the driving part with a fastening tool. For example, as shown in Figure 4 the driving part can be a hexagonal head 10, and the fastening tool can adopt a hexagonal wrench 11; of course, a screwdriver and a straight / cross slot screw head can also be used.

[0050] The working principle of the present application is as follows: ①As shown in Figure 2 , before installation, the movable mold 2 and the tail plate 3 are in a state of moving away from each other, which also provides enough space for the installation of the connecting rod assembly 1. ②The worker can first connect the bottom end of the connecting rod assembly 1 with the hinge seat 4 on the closing oil cylinder below the test system, and the connection mode of the three ends of the connecting rod assembly 1 with the three hinge seats 4 in the test system is the same, and the hinge seat 4 below does not contain the supporting plate 15 and other structures due to the positional relationship, so it will not be described in detail here. ③We take the connection of the left and right ends of the connecting rod assembly 1 with the hinge seats 4 on the movable mold 2 and the tail plate 3 of the test system as an example for specific description, the initial state of the hinge seat 4 is shown in Figure 9 , the limiting piece 9 is in a storage state, and the supporting plate 15 is in an unfolded state, the worker can rotate and adjust the left and right ends of the connecting rod assembly 1 to be placed on the corresponding supporting plate 15, at this time, the left and right ends of the connecting rod assembly 1 are almost in a straight line. ④Install the left end of the connecting rod assembly 1 first, the worker holds the left end of the connecting rod assembly 1 with one hand, and inserts the pin shaft 7 into the corresponding mounting hole of the ear plate 402 and the connecting rod assembly 1 with the other hand, inserts the pin shaft 7 into an appropriate position, and rotates the pin shaft 7 to make the limiting groove 14 and the limiting piece 9 in an appropriate corresponding position. Then insert the hexagonal wrench 11 into the hexagonal head 10, and then rotate the lead screw 12 in the opposite direction, as known from the above, under the action of the transmission assembly 8, the limiting piece 9 rotates relatively close and cooperates with the limiting groove 14 of the pin shaft 7, as shown in Figure 4At the same time, the screw rod 12 drives the worm 1302 to rotate, the worm 1302 acts on the two worm gears 1301, and then the two supporting plates 15 rotate relative to each other and are attached to the bottom end of the ear plate 402, thereby completing the installation; similarly, the right end of the connecting rod assembly 1 is operated again. Finally, the connecting rod assembly 1 is tested for various performance indicators by the test system.

[0051] It should be noted that the rotation number of the limiting piece 9 and the transmission assembly 8, the supporting plate 15 and the transmission device 13 and the screw rod 12 can be adaptively set according to actual conditions. For example, the rotation range of the limiting piece 9 is one hundred and eighty degrees (i.e. half a circle), and the commonly used single-stage worm 1302 and worm gear 1301 transmission ratio range is about 5:1 to 100:1, we assume that the transmission ratio in this application is 30:1, which means that the worm 1302 rotates 30 times, and the worm gear 1301 rotates 1 time, so the inner hexagonal wrench 11 needs to rotate 15 times. Assuming that the moving distance of the transmission block one 801 is 15 centimeters, and the lead of the screw rod 12 can be set to 10 millimeters, that is, the screw rod 12 rotates one circle, the transmission block one 801 moves 10 millimeters, and 15 circles are 15 centimeters. That is, by reasonably setting the lead of the screw rod 12 and the transmission ratio and other parameters, the rotation angle of the limiting piece 9 and the moving distance of the transmission block one 801 can be accurately controlled, and the movement of each component during installation is coordinated and consistent. In addition, from the above installation process, it can be seen that the movement of the entire limiting piece 9 and the supporting plate 15 can be realized by rotating the screw rod 12 by a set number of turns, greatly improving the installation efficiency, and thereby improving the test efficiency of the connecting rod assembly 1.

[0052] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
