Description

TECHNICAL FIELD

[0002] The die casting machine column frame component is connected together by a corinthian column through a head plate, a middle plate and a tail plate, and the middle plate reciprocates between the head plate and the tail plate through a mold locking connecting rod mechanism. Before the column frame component is assembled with the die casting machine base, the column frame component needs to be tested to ensure that it can operate normally after assembly and avoid production accidents caused by component quality problems.

[0003] In the prior art, as shown in Figure 1 , the column frame component is hoisted on the test table for relevant performance testing. As shown in Figure 2 , there is a sliding foot at the lower part of the middle plate of the column frame component, which supports the middle plate on the steel belt of the test table, thereby reducing the wear of the corinthian column during reciprocating motion of the middle plate; the bottom of the sliding foot is a copper plate, and the copper plate and the steel belt are in contact sliding fit. However, due to installation errors, the moving direction (or the length direction of the column frame component) of the sliding foot is not parallel to the length direction of the steel belt, which affects the measurement accuracy of the mold closing electronic ruler (for details, please refer to CN114001947B).

DETAILED DESCRIPTION

[0031] Hereinafter, the 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.

[0032] In the description of the application, it should be noted that, for orientation words, such as 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 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 application.

[0033] 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 do not necessarily have to follow an serial order or a particular chronological sequence.

[0034] Further analysis of the defects existing in the prior art test system shows that: Figure 1 and Figure 2 As shown in the drawings, the steel strip assembly 3 is fixedly installed on the test bench 1, and its position is fixed. The column part 2 is generally installed on the test bench 1 by means of bolt fasteners, i.e. there are a plurality of bolt holes at the top end of the test bench 1, and as the test system is used for a long time, the frequent disassembly and assembly of the column part 2 will cause the size of the bolt holes to expand, and some different types of column parts 2 will share the bolt holes on the test bench 1, and the types of bolts can also be different, so it is easy to cause the column part 2 to be not parallel to the steel strip assembly 3 after installation.

[0035] During testing, a closing mold electronic ruler 4 is arranged between the slide foot 203 at the bottom end of the middle plate 201 and the steel strip assembly 3, which includes a displacement sensor 401 and a displacement sensing head 402. The displacement sensor 401 is installed at the side of the steel strip assembly 3, and the displacement sensing head 402 is installed at the side of the slide foot 203 through a bracket. The displacement of the closing mold is detected by the cooperation of the displacement sensor 401 and the displacement sensing head 402, and the non-parallel condition will affect the displacement detection data of the closing mold, thereby affecting the accuracy of the test. On the other hand, the normal sliding wear marks of the slide foot 203 and the steel strip assembly 3 are along the length direction of the two, so if the two are not parallel, the wear will be aggravated, affecting the service life. Furthermore, in the prior art, the cooperation between the slide foot 203 and the steel strip assembly 3 is to adjust the height of the slide foot 203 manually, which is time-consuming, laborious and troublesome.

[0036] Therefore, the inventors of the present application have developed a die casting machine column part test system, which, as shown in one embodiment of Figures 1 to 13 includes a test bench 1, a column part 2, a steel strip assembly 3 and a detection device 7. The column part 2 is generally installed on the test bench 1 in cooperation with hoisting equipment, the steel strip assembly 3 is installed on the test bench 1 through an adjusting device, the detection device 7 is installed on the steel strip assembly 3 and cooperates with the column part 2, and the adjusting device includes adjusting assembly one 5 and adjusting assembly two 6.

[0037] It can be understood that after the column component 2 is installed on the test table 1, the detection device 7 detects the column component 2, and then judges the parallelism of the steel belt assembly 3 and the column component 2 through the detection data. If the two are not parallel, the adjusting assembly one 5 drives the steel belt assembly 3 to rotate until the steel belt assembly 3 and the column component 2 are parallel. Then the adjusting assembly two 6 automatically adjusts the height of the steel belt assembly 3 to make the steel belt assembly 3 move up and abut against the slide foot 203.

[0038] Therefore, through the cooperation of the adjusting assembly one 5, the adjusting assembly two 6 and the detection device 7, the steel belt assembly 3 can be adjusted to be parallel to the installed column component 2, and the height of the steel belt assembly 3 can be automatically adjusted to cooperate with the slide foot 203, without manual operation, thereby improving the efficiency and accuracy of the test.

[0039] Specifically, as shown in Figure 4 The adjusting assembly one 5 includes a driving component 501, and the adjusting assembly two 6 includes a telescopic component 601 and a support plate 602. The telescopic component 601 is vertically installed on the test table 1 and connected with the support plate 602 at a telescopic end. The steel belt assembly 3 is horizontally rotatably installed on the top end of the support plate 602 through a rotating shaft 8. The driving component 501 is installed on the test table 1 and connected with the rotating shaft 8 at an output end through a spline.

[0040] It can be understood that when the height is adjusted, the telescopic movement of the telescopic component 601 can adjust the height of the steel belt assembly 3 through the support plate 602. When the rotation is adjusted, the rotation of the output end of the driving component 501 can drive the steel belt assembly 3 to rotate through the rotating shaft 8, and the spline cooperation prevents the two adjustments from interfering with each other. It should be understood that those skilled in the art will directly install the driving component 501 on the support plate 602 when designing two adjusting assemblies, thereby achieving independent adjustment of the two. However, this requires a larger installation space between the steel belt assembly 3 and the support plate 602, and the support plate 602 needs to have greater strength, and the telescopic component 601 needs to have greater power, which obviously increases the manufacturing cost. The specific installation mode of the two adjusting assemblies of the present application can reduce the installation space and reduce the manufacturing cost.

[0041] It should be noted that the specific structure and working principle of the telescopic component 601 and the driving component 501 are known to those skilled in the art, and therefore will not be described in detail here. Common telescopic components 601 include hydraulic cylinders, pneumatic cylinders and linear motors, and common driving components 501 include motors, rotary air cylinders or rotary hydraulic cylinders.

[0042] As shown in Figure 4As shown, the detection device 7 includes a mounting frame 701 and multiple distance sensors 702. The mounting frame 701 is mounted on the steel strip assembly 3, and the distance sensors 702 are mounted at corresponding positions on both sides of the mounting frame 701. For example, a pair of distance sensors 702 are used to detect the distance to the side of the column frame component 2. We consider the steel strip assembly 3 and the side of the column frame component 2 as two planes. If the two planes are parallel, it means that the distance detection data of the two distance sensors 702 are equal. Therefore, the steel strip assembly 3 is rotated and adjusted according to the measured distance data until the two are parallel.

[0043] Further optimization reveals that the flat portion of the side of the column frame component 2 may be relatively small, thus affecting the actual measurement of the distance sensor 702. However, the golem column 202 on the column frame component 2 is a regular cylinder of sufficient length; therefore, the parallelism can be judged by the distance between the distance sensor 702 and the golem column 202. It is understandable that... Figure 5 As shown, the mounting bracket 701 includes multiple clamps 7011 (at least two; for ease of description, two are used as an example below). The two clamps 7011 are connected as one unit by a connecting plate. During testing, the two clamps 7011 are installed on the steel belt assembly 3, and after installation, the axis of the clamps 7011 is parallel to the length direction of the steel belt assembly 3. The distance sensor 702 is installed at the corresponding position of the two clamps 7011.

[0044] For example, such as Figure 6 As shown, four distance sensors 702 (labeled I, II, III, and IV) are installed on the left and right sides of the two clamps 7011 corresponding to the golem 202. Distance sensor I measures the distance D1 between itself and the golem 202; distance sensor II measures the distance D2; distance sensor III measures the distance d1; and distance sensor IV measures the distance d2. If the column frame component 2 and the steel band assembly 3 are parallel, then the measured data for D1 and d1 are the same, and the measured data for D2 and d2 are the same. Therefore, the parallelism between the column frame component 2 and the steel band assembly 3 can be judged based on the distance values ​​of D and d. If they are not parallel, the parallelism can be adjusted by rotating the steel band assembly 3.

[0045] As a further description of the above embodiments: as Figure 5 and Figure 7As shown, the mounting frame 701 further comprises a horizontal rod 7013 and a vertical rod 7012. It can be understood that, when the detection device 7 is used, the vertical rod 7012 is inserted through the bottom end on the fixed plate 9 on the steel belt assembly 3, and the vertical rod 7012 can be adjusted up and down, and when adjusted to the appropriate height, the vertical rod 7012 is locked by the limiting part one 10. The first end of the horizontal rod 7013 is horizontally slid on the top end of the vertical rod 7012, and of course the horizontal rod 7013 can be adjusted left and right, and when adjusted to the appropriate position, the horizontal rod 7013 is locked by the limiting part two 11. That is, the clamp 7011 can be adjusted up, down, left and right by the sliding of the horizontal rod 7013 and the vertical rod 7012, so that the detection clamp 7011 can be better adjusted and set on the outside of the column 202, facilitating testing. After the parallelism test is adjusted, the vertical rod 7012 can be pulled out of the fixed plate 9, and the entire detection device 7 can be disassembled, which will not interfere with the mold test of the subsequent column part 2, which is simple and convenient.

[0046] It should be noted that the limiting part one 10 and the limiting part two 11 can be limiting bolts, that is, the locking and unlocking of the horizontal rod 7013 and the vertical rod 7012 are achieved by tightening and loosening the limiting bolts.

[0047] As shown in the figure, Figure 8 Because the middle position of the bottom end of the steel belt assembly 3 is only installed on the support plate 602 by a rotating shaft 8, that is, the two ends of the steel belt assembly 3 are in a suspended state, and thus the stability of the steel belt assembly 3 is poor. Therefore, guide wheels 13 can be installed on the both sides of the bottom end of the steel belt assembly 3 through support columns 12, and guide grooves 14 are arranged on the both sides of the top end of the support plate 602, and the two ends of the steel belt assembly 3 are limited and supported by the cooperation of the guide wheels 13 and the guide grooves 14, thereby improving the stability of the steel belt assembly 3.

[0048] Based on the above embodiment, there is still a problem that because the guide wheels 13 and the guide grooves 14 are movably matched, the limitation of the steel belt assembly 3 in the circumferential direction still depends on the rotating shaft 8 in the middle, and thus when the sliding foot 203 is in contact and sliding cooperation with the steel belt assembly 3, the stability of the steel belt assembly 3 is still poor.

[0049] Therefore, in order to solve the above technical problems, as shown in the figure, Figures 9 to 13As shown, the pressing plate 15 can be vertically slidably installed on both sides of the top end of the support plate 602 by springs, and the pressing plate 15 is matched with the test bench 1 through the transmission structure 17. It can be understood that the pressing plate 15 is away from the guide wheel 13 in the normal state under the action of the elastic force, so as not to affect the rotation adjustment of the steel belt assembly 3, and when the steel belt assembly 3 is adjusted to move up and cooperates with the slide foot 203, the input end of the transmission structure 17 will be extruded and matched with the test bench 1, and then the output end of the transmission structure 17 will drive the pressing plate 15 to move and abut on the guide wheel 13, so that if the guide wheel 13 moves in the guide groove 14, it will generate a great damping effect due to the pressure, thereby achieving the locking of the guide wheel 13 and improving the stability of the steel belt assembly 3.

[0050] The structure of the transmission structure 17 is not limited in the present application, and two specific embodiments are provided below for reference:

[0051] Structure one: as shown in the figure, Figure 9 the transmission structure 17 includes a transmission block 1701, and the transmission block 1701 has a wedge surface (i.e. an inclined surface) at both ends, and the transmission block 1701 is horizontally slidably installed at the top end of the support plate 602.

[0052] It can be understood that, as shown in the figure, Figure 10 before the steel belt assembly 3 moves up, the left end of the transmission block 1701 is not matched with the test bench 1, and the right end of the transmission block 1701 is not matched with the pressing plate 15. When the steel belt assembly 3 moves up, the first end (i.e. the left end) of the transmission block 1701 is wedge-shaped extruded and matched with the test bench 1, and the transmission block 1701 will move right under the action of the extrusion force, so that the second end (i.e. the right end) of the transmission block 1701 is wedge-shaped extruded and matched to drive the pressing plate 15 to vertically move down, and the pressing plate 15 abuts on the top end of the guide wheel 13 to achieve the locking of the guide wheel 13, as shown in the figure, Figure 11 It should be noted that when the wedge surface of the left end of the transmission block 1701 is wedge-shaped matched with the test bench 1, the guide wheel 13 will be in a stable locking state regardless of the height of the steel belt assembly 3 moving up. Similarly, when the steel belt assembly 3 moves down and the transmission block 1701 is disengaged from the test bench 1, the transmission block 1701 will move left under the action of the elastic force and be separated from the pressing plate 15, and the pressing plate 15 will move up under the action of the elastic force and be separated from the guide wheel 13, thereby releasing the locking of the guide wheel 13.

[0053] Further preferably, as shown in the figure, Figure 9As shown, the specific mounting mode of the pressing plate 15 is that the pressing plate 15 can be sleeved and arranged outside the support column 12, of course, the outside of the pressing plate 15 is provided with a avoiding groove 16 for the movement of the support column 12, and the bottom end of the pressing plate 15 is provided with a guide column which is vertically and slidingly inserted into the support plate 602 and connected with the support plate 602 through a spring, so as to realize the vertical and elastic mounting of the pressing plate 15. Such mounting mode can realize the stable mounting of the pressing plate 15, and can also improve the contact area when the pressing plate 15 cooperates with the guide wheel 13, so as to realize the stable locking of the guide wheel 13.

[0054] Structure two: as shown in Figure 12 and Figure 13 shown, the transmission structure 17 includes a connecting rod one 1702 and a connecting rod two 1703, the connecting rod one 1702 is rotatably mounted at the top end of the support plate 602, and the two ends of the connecting rod two 1703 are respectively hinged to the first end (i.e. the right end) of the connecting rod one 1702 and the top end of the pressing plate 15.

[0055] As can be understood, as shown in Figure 12 , before the steel belt assembly 3 is moved up, the second end (i.e. the left end) of the connecting rod one 1702 is not cooperated with the test bench 1. When the steel belt assembly 3 is moved up, the left end of the connecting rod one 1702 is counterclockwise rotated under the extrusion cooperation of the test bench 1, that is, the right end of the connecting rod one 1702 is upward rotated, and the connecting rod one 1702 can pull the pressing plate 15 to vertically move up through the connecting rod two 1703, so that the pressing plate 15 is abutted to the bottom end position of the guide wheel 13 to realize the locking of the guide wheel 13, as shown in Figure 13 . It should be noted that when the steel belt assembly 3 continues to move up, the connecting rod one 1702 will always keep the extrusion cooperation state with the test bench 1, that is, the guide wheel 13 will always be in a stable locking state. Similarly, when the steel belt assembly 3 is moved down and the connecting rod one 1702 is separated from the test bench 1, the pressing plate 15 will move down under the action of the elastic force and be separated from the guide wheel 13, so as to release the locking of the guide wheel 13, and of course the connecting rod one 1702 will also return to the initial uncooperative state.

[0056] Further, in order to reduce the friction force between the left end of the connecting rod one 1702 and the test bench 1, a roller can be arranged at the left end of the connecting rod one 1702, so that the connecting rod one 1702 can be smoothly cooperated with the test bench 1, and the service life is improved.

[0057] It should be noted that both structures can satisfy the locking of the guide wheel 13, and those skilled in the art can select according to the actual situation. In addition, the locking of the guide wheel 13 is realized by using the extrusion cooperation between the guide wheel 13 and the test bench 1 as the power source, so as to realize the mechanical locking of the guide wheel 13, that is, the locking is realized without the need of electric drive. Such locking mode is simple in structure and safe and reliable.

[0058] The working principle of the present application is as follows:

[0059] ①Firstly, the column frame component 2 is hoisted to a suitable position on the test table 1 by hoisting equipment, and then the column frame component 2 is fixedly connected with the test table 1 through bolts, thereby completing the installation of the column frame component 2. ②The detection device 7 is inserted into the fixed plate 9 of the steel belt assembly 3 through the vertical rod 7012, and then the position of the clamp 7011 is adjusted through the sliding adjustment of the vertical rod 7012 and the horizontal rod 7013, after adjustment, the limiting bolt is tightened for locking, and the clamp 7011 is wrapped outside the Corinth column 202. ③The distance sensor 702 on the clamp 7011 measures the distance between the Corinth column 202, and judges whether the column frame component 2 and the steel belt assembly 3 after installation are in parallel state through distance detection data, if not parallel, the motor drives the steel belt assembly 3 to rotate and adjust through the rotating shaft 8 until it is parallel with the column frame component 2; then the detection device 7 is separated from the fixed plate 9 for disassembly. ④The telescopic component 601 drives the steel belt assembly 3 to move upwards, so that the steel belt assembly 3 cooperates with the slide foot 203 at the bottom end of the middle plate 201, at the same time, the input end of the transmission structure 17 is extruded and matched with the test table 1, and then the output end of the transmission structure 17 drives the pressing plate 15 to move and abut on the guide wheel 13, thereby locking the guide wheel 13 to ensure that the steel belt assembly 3 stably cooperates with the slide foot 203. Finally, the displacement sensor head 402 is installed on the side of the slide foot 203 through the bracket, so that the displacement sensor head 402 cooperates with the displacement sensor 401 after adjustment, and then the related test of the column frame component 2 can be carried out.

[0060] 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. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.

When the steel belt assembly moves upward and cooperates with the sliding foot, the transmission structure is adapted to drive the pressure plate to move and abut against the guide wheel under the action of the test bench, so as to lock the guide wheel. The transmission structure includes a transmission block, which is elastically and horizontally slidably mounted on the top of the support plate. When the steel belt assembly moves upward, the first end of the transmission block moves horizontally by wedge-shaped compression with the test bench, thereby causing the second end of the transmission block to drive the pressure plate to move vertically until it abuts against the guide wheel. Alternatively, the transmission structure may include a first connecting rod and a second connecting rod. The first connecting rod is rotatably mounted on the top of the support plate via its central portion. The two ends of the second connecting rod are respectively hinged to the first end of the first connecting rod and the top of the pressure plate. When the steel strip assembly moves upward, the second end of the first connecting rod is adapted to rotate under the compression of the test bench. Consequently, the first connecting rod is adapted to pull the pressure plate vertically through the second connecting rod until it abuts against the guide wheel.

The mounting frame is mounted on the steel strip assembly, and the distance sensors are mounted on the mounting frame. The distance sensors determine the parallelism between the steel strip assembly and the column frame component by detecting the distance between them.

3. The die-casting machine column frame component testing system as described in claim 2, characterized in that: The mounting bracket includes at least one pair of clamps connected together. The clamps are detachably installed on the steel strip assembly and their axes are parallel to the steel strip assembly. The distance sensor is installed at the corresponding position of the clamp and cooperates with the column of the column frame component.

4. The die-casting machine column frame component testing system as described in claim 3, characterized in that: The mounting frame also includes a horizontal bar and a vertical bar. The vertical bar is vertically slidably inserted into a fixing plate on the steel strip assembly at its bottom end and cooperates with the fixing plate through a limiting member one. The horizontal bar is horizontally slidably inserted into the top end of the vertical bar at its first end and cooperates with the vertical bar through a limiting member two. The second end of the horizontal bar is connected to the clamp. The clamp is adapted to be adjusted in position by sliding the vertical bar and the horizontal bar; after adjustment, the first limiting member is adapted to lock the vertical bar, and the second limiting member is adapted to lock the horizontal bar.

5. The die-casting machine column frame component testing system as described in any one of claims 1-4, characterized in that: The pressure plate is sleeved on the outside of the support column, and the outside of the pressure plate is provided with a clearance groove for the support column to move. The four corners of the bottom end of the pressure plate are connected to the support plate through guide posts and springs to realize the vertical elastic installation of the pressure plate.
