Description

Technical Field

[0001] The present application relates to the technical field of mechanical equipment, and in particular to an installation and disassembly tool for a supporting block of a connecting rod mechanism. Background Art

[0002] The connecting rod mechanism is one of the most commonly used key components in mechanical engineering fields such as power engineering, light industry machinery, and the automotive industry. It solves the key circular motion or force transmission in simple harmonic oscillation, and realizes rotation, swing, movement, plane or space, etc., as well as known motion laws and known trajectories. The connecting rod mechanism has important applications in the field of tobacco machinery, such as silk making and re-baking equipment in vibration trough conveying, screening, etc. The number can reach hundreds or thousands, and it has an irreplaceable role, and it is a key component of simple harmonic oscillation. Among the connecting rod mechanisms, the most commonly used are crank rocker mechanisms and double rocker mechanisms. Since the support block of the rocker fulcrum is affected by the kinematic pair, it is necessary to install a damping member on the support block to improve its mechanical properties, such as noise reduction and shock absorption.

[0003] Damping parts are generally made of high-quality rubber damping and shock-absorbing materials, such as butyl recycled rubber, which has good shock absorption, heat resistance, chemical stability and long service life. However, since the rocker-type connecting rod mechanism of silk making and re-baking equipment works for a long time, more than 10 hours a day, the damping parts fail quickly, which greatly affects the performance of the vibration trough. Therefore, they need to be repaired or replaced regularly, which is labor-intensive.

[0004] In the field of general mechanical engineering or professional manufacturers, the installation and disassembly of connecting rod mechanism support blocks and damping parts are mostly completed on assembly lines or in professional equipment. The technology is mature and it is quick and convenient. However, user units do not have relevant equipment or tools to complete the disassembly and assembly, and manual hammering is often used during maintenance. Therefore, the connecting rod mechanism and support blocks are often easily damaged and cannot be repaired. They are easily scrapped, which increases the maintenance cost. Utility Model Content

The number of damping members corresponds to that of the mounting frame, the bottom surface has the same cross-sectional size as the mounting axis, grooves corresponding to the number of damping members are provided on the side surface, and the shape and position of each groove respectively correspond to the shape and position of a damping member; the mounting frame includes a baffle and a support foot connected to the baffle, and when the mounting frame is placed on the supporting surface, the support foot can support the baffle to a distance greater than the height of the polygonal pyramid wedge tip, wherein a through hole is provided on the baffle, the size of the through hole is smaller than the size of the mounting hole, and larger than the size of the polygonal pyramid wedge tip, so that the damping member abutting against the inner wall of the mounting hole cannot pass through the through hole, and the polygonal pyramid wedge tip can pass through the through hole.

[0006] In some embodiments, the baffle has a mounting boss protruding from the surface of the baffle, the through hole is arranged on the mounting boss, and the size of the mounting boss is less than or equal to the size of the mounting hole.

[0007] In some embodiments, the mounting hole is a square hole, the mounting boss is a regular quadrangular prism, and when the mounting boss is inserted into the mounting hole, the size of the mounting boss is also set to limit the rotation of the mounting hole on the mounting boss.

[0008] In some embodiments, a limit plate is further provided on the mounting frame, the limit plate is perpendicular to the baffle plate, at least two limit screws are provided on the limit plate, and the at least two limit screws are distributed in a direction parallel to the baffle plate.

[0009] In some embodiments, the installation and disassembly tool further includes a disassembly frame, which includes a base plate and a plurality of support plates vertically connected to the base plate, and the plurality of support plates enclose a space adapted to the size of the support block.

[0010] In some embodiments, there are two support plates, the two support plates are parallel and the distance between the two support plates is greater than or equal to the width of the base of the support block, and the height of the support plate is greater than or equal to the length of the installation axis of the support block.

[0011] In some embodiments, the damping member is cylindrical, the number of damping members is four, the mounting axis is a square axis, the polygonal pyramid tip is a regular quadrangular pyramid, and a cylindrical groove is provided on each side of the polygonal pyramid tip. The intersection of the cylinder where the cylindrical surface is located and the side surface forms two line segments with the same endpoints, and the intersection with the top surface forms an arc, and the axis of the cylinder where the cylindrical surface is located forms an angle with the side surface of the polygonal pyramid tip.

[0013] In some embodiments, the diameter of the cylinder where the cylindrical surface is located is smaller than the diameter of the damping member.

Since the cross-sectional size of the bottom surface is the same as that of the mounting axis, the mounting axis can enter the mounting hole together with the polygonal pyramid split tip.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection claimed in the present application.

[0031] To at least partially resolve the user's installation and removal issues with the linkage support block, please refer to Figure 1 to Figure 9 , an embodiment of the present application provides a tool for installing and disassembling a connecting rod mechanism support block. The connecting rod mechanism may be a connecting rod mechanism in tobacco machinery and equipment, such as a connecting rod mechanism in silk making and re-roasting equipment, etc. By way of example, the connecting rod mechanism may be a crank rocker mechanism or a double rocker mechanism. Of course, the connecting rod mechanism may also be other types of connecting rod mechanisms in other equipment, which is not limited in the present application. The connecting rod mechanism support block (also referred to as the support block in the present application) may be a structure for installing a rocker fulcrum in the connecting rod mechanism. The support block is easily affected by the kinematic pair, and therefore it is often necessary to use it in conjunction with a damping member to achieve functions such as shock absorption and noise reduction. The material of the damping member may be a rubber damping and shock absorbing material, such as butyl recycled rubber, etc. By way of example, the damping member may be cylindrical and may have a size of ¢20×72mm.

[0032] like Figure 3 As shown, the support block 3 includes a mounting shaft 31 and a base connected to one end of the mounting shaft 31. The base may be provided with a screw hole 32 to facilitate installation of other structures on the connecting rod mechanism 2. Figure 2 When the support block 3 is installed in the mounting hole 21 of the connecting rod mechanism 2, a plurality of damping members 1 are arranged between the mounting shaft 31 and the mounting hole 21. For example, the mounting hole 21 can be a square hole, and the number of damping members 1 can be 4. The damping members 1 abut against the outer wall of the mounting shaft 31 and the inner wall of the mounting hole 21 at the same time to absorb the vibration of the support block 3 caused by the movement of the connecting rod mechanism 2.

[0033] Please also read Figure 1 , Figure 4 , Figure 6 as well as Figure 7The installation and disassembly tool comprises a polygonal pyramid splitting tip 4 and a mounting frame 6. The polygonal pyramid splitting tip 4 has a bottom surface, a top surface 42 whose area is smaller than the bottom surface, and a plurality of side surfaces connecting the bottom surface and the top surface 42. The polygonal pyramid splitting tip 4 of this structure can form a wedge shape, which is conducive to the polygonal pyramid splitting tip 4 entering the mounting hole 21 with the damping member 1. In this embodiment, the polygonal pyramid splitting tip 4 can be a regular quadrangular pyramid, the bottom surface and the top surface 42 can both be square, and the side length of the top surface 42 can be smaller than the side length of the bottom surface. Of course, in other embodiments, the polygonal pyramid splitting tip 4 can also be a pentagonal pyramid, a hexagonal pyramid, etc. The bottom surface has the same cross-sectional size as the mounting shaft 31. The mounting shaft 31 can be a square shaft, and the cross section of the mounting shaft 31 can be a square. The side length of the cross section of the mounting shaft 31 can be the same as the side length of the bottom surface of the polygonal pyramid splitting tip 4. The side surface is provided with grooves 41 corresponding to the number of damping elements 1. The shape and position of each groove 41 respectively correspond to the shape and position of a damping element 1. The number of grooves 41 can be the same as the number of damping elements 1. The shape of the grooves 41 can correspond to the shape of the damping element 1. The grooves 41 can limit the damping element 1 to prevent the damping element 1 from deviating from its installation position under the action of the polygonal pyramid wedge 4. At the same time, the opening of the grooves 41 is also more conducive to the polygonal pyramid wedge 4 entering the installation hole 21 when the damping element 1 is present. Figure 4 As shown, the mounting frame 6 includes a baffle and a support leg connected to the baffle. When the mounting frame 6 is placed on the support surface, the support leg can support the baffle to a distance greater than the height of the multi-sided pyramid cleavage 4, so that the multi-sided pyramid cleavage 4 can smoothly fall under the baffle. The baffle and the support leg can be connected by welding, or they can be integrally formed, for example, by machining the entire piece. A through hole is provided on the baffle, and the size of the through hole is smaller than the size of the mounting hole 21, and larger than the size of the multi-sided pyramid cleavage 4, so that the damping member 1 abutting against the inner wall of the mounting hole 21 cannot pass through the through hole, and the multi-sided pyramid cleavage 4 can pass through the through hole. This arrangement can limit the damping member 1 and prevent the damping member 1 from being pushed out of the mounting hole 21 by the multi-sided pyramid cleavage 4. Exemplarily, the mounting hole 21 can be a square hole with a side length A=55mm, the through hole on the baffle can be a square hole of 42×42mm, the mounting axis 31 of the support block 3 can be a regular quadrangular prism of 38×38×82mm, the bottom surface of the polygonal pyramid 4 can be a square with a side length of 38mm, and the length of the polygonal pyramid 4 can be 100mm.

[0034] The embodiment of the present application provides a tool for installing and disassembling a supporting block of a connecting rod mechanism. When installing the supporting block 3, the connecting rod mechanism 2 can be placed on the mounting frame 6, and the elasticity and plasticity of the damping member 1 can be used to gradually insert the polygonal pyramid split tip 4 into the mounting hole 21. Since the cross-sectional dimensions of the bottom surface and the mounting axis 31 are the same, the mounting axis 31 can enter the mounting hole 21 together with the polygonal pyramid split tip 4. When the mounting axis 31 gradually enters the mounting hole 21, the baffle plate itself can block the movement of the damping member 1, and the polygonal pyramid split tip 4 moves out from the other side of the mounting hole 21 and falls under the baffle plate through the through hole on the mounting frame 6, thereby completing the installation of the supporting block 3; when disassembling the supporting block 3, a force can be applied to the mounting axis 31 of the supporting block 3 installed in the mounting hole 21 through the top surface 42 or the bottom surface of the polygonal pyramid split tip 4, thereby ejecting the supporting block 3 and completing the disassembly of the supporting block 3. Therefore, the installation and disassembly tooling of the connecting rod mechanism support block provided in the embodiment of the present application can realize the installation and disassembly of the support block 3, reduce the damage during installation and disassembly, improve the efficiency of installation and disassembly, reduce maintenance costs, and the disassembly process is labor-saving, lossless, safe and reliable.

[0035] In some embodiments, the baffle has a mounting boss 61 protruding from the baffle surface, and a through hole is provided on the mounting boss 61, and the size of the mounting boss 61 is less than or equal to the size of the mounting hole 21. In this embodiment, the mounting boss 61 can enter the mounting hole 21, so that it is easier to limit the movement of the damping member 1. At the same time, the mounting boss 61 can also play a positioning role, so that when the connecting rod mechanism 2 is placed on the mounting table, the mounting hole 21 is aligned with the mounting boss 61.

[0036] In some embodiments, the mounting boss 61 is in the shape of a regular quadrangular prism. When the mounting boss 61 is inserted into the mounting hole 21, the size of the mounting boss 61 is also set to limit the rotation of the mounting hole 21 on the mounting boss 61. Through this setting, when the mounting hole 21 of the connecting rod mechanism 2 is set on the mounting boss 61, the mounting boss 61 can realize the limit of the connecting rod mechanism 2 in the plane of the baffle, and reduce the swing amplitude of the connecting rod mechanism 2 around the mounting boss 61. In this embodiment, the size of the mounting boss 61 can be equal to or slightly smaller than the size of the mounting hole 21, so that the connecting rod mechanism 2 can hardly rotate on the mounting boss 61. Here, slightly smaller can be interpreted as the ratio of the size of the mounting boss 61 to the size of the mounting hole 21 is between 95% and 100%. For example, when the mounting hole 21 is a square hole with a side length A=55mm, the side length of the mounting boss 61 can be 54mm, and the height of the mounting boss 61 can be 10mm.

[0037] In some embodiments, a limit plate is also provided on the mounting frame 6, the limit plate is perpendicular to the baffle, and at least two limit screws 62 are provided on the limit plate, and at least two limit screws 62 are distributed in a direction parallel to the baffle. In this embodiment, the limit screw 62 can change the extended length by rotation, so as to support the connecting rod mechanism 2, further prevent the connecting rod mechanism 2 from swinging, and realize the limit function of the connecting rod mechanism 2. At the same time, the limit screw 62 can correct the installation position of the connecting rod mechanism 2, which is suitable for batch installation and improves efficiency. In some embodiments, a screw hole can be opened on the connecting rod mechanism 2, and the limit screw 62 can be screwed into the screw hole, so as to realize a more secure limit on the connecting rod mechanism 2.

[0038] like Figure 5 and Figure 8 As shown, in some embodiments, the installation and disassembly tooling also includes a disassembly frame 9, which includes a base plate and a plurality of support plates 91 vertically connected to the base plate, and the plurality of support plates 91 enclose a space that matches the size of the support block 3. The support plates 91 and the base plate can be connected by welding. In this embodiment, the disassembly frame 9 of this structure supports the connecting rod mechanism 2 through the support plates 91. At the same time, when the connecting rod mechanism 2 is supported by the support plates 91, the support block 3 can initially enter the space enclosed by the support plates 91. When the support block 3 is pushed out by the multi-prism splitting tip 4, the support block 3 can fall into the space enclosed by the support plates 91, thereby preventing the support block 3 from falling uncontrollably during disassembly and causing damage to the support block 3.

[0039] In some embodiments, the number of support plates 91 is two, the two support plates 91 are parallel, and the distance between the two support plates 91 is greater than or equal to the width of the base of the support block 3, and the height of the support plate 91 is greater than or equal to the length of the mounting shaft 31 of the support block 3, so as to achieve that the size of the space surrounded by the two support plates 91 is adapted to the support block 3. In this embodiment, the distance between the two support plates 91 can be slightly greater than the width of the base of the support block 3, and the height of the support plate 91 can be slightly greater than the length of the mounting shaft 31 of the support block 3. Exemplarily, the width of the base of the support block 3 can be 66 mm, and the distance between the two support plates 91 can be 70 mm; the length of the mounting shaft 31 can be 82 mm, and the height of the support plate 91 can be 135 mm. The width of the support plate 91 can be close to the length of the base of the support block 3, for example, the length of the base of the support block 3 is 152 mm, and the width of the support plate 91 can be 150 mm.

[0040] In some embodiments, the damping member 1 is cylindrical, the number of damping members 1 is four, the mounting axis is a square axis, the polygonal pyramid tip 4 is a regular quadrangular pyramid, and a cylindrical groove 41 is provided on each side of the polygonal pyramid tip 4. The intersection of the cylinder where the cylindrical surface is located and the side forms two line segments with the same endpoints, and the intersection with the top surface 42 forms an arc, and the axis of the cylinder where the cylindrical surface is located forms an angle with the side of the polygonal pyramid tip 4. In this embodiment, the cylindrical groove 41 can better match the shape of the damping member 1. At the same time, the axis of the cylinder where the cylindrical surface is located forms an angle with the side of the polygonal pyramid tip 4, so that the damping member 1 and the polygonal pyramid tip 4 are firmly clamped during the insertion into the connecting rod mounting hole 21. Preferably, in some embodiments, the angle α formed by the polygonal pyramid splitting tip 4 relative to the two side surfaces is 5.72°, so that when the damping piece set of four damping pieces 1 is placed in the mounting hole 21 of the connecting rod mechanism 2, the polygonal pyramid splitting tip 4 has a variable tension; the angle β formed by the axis of the cylinder where the cylindrical surface is located and the side surface of the polygonal pyramid splitting tip 4 is 3.01°, and the chord length obtained by the cylinder where the cylindrical surface is located and the top surface 42 of the polygonal pyramid splitting tip 4 can be 15.84 mm, and the length tangent to the side surface of the polygonal pyramid splitting tip 4 can be 80.02 mm. The material of the polygonal pyramid splitting tip 4 can be tool steel T10, which is heat treated during manufacturing and quenched to HRC60~65. In some embodiments, the groove 41 can also have a conical surface groove 41. In some embodiments, the diameter of the cylinder where the cylindrical surface is located is smaller than the diameter of the damping piece 1. This arrangement is more conducive to the clamping of the damping piece 1 by the groove 41. For example, the diameter of the damping element 1 is Φ20 mm, and the diameter of the cylinder where the cylindrical surface is located is Φ18 mm.

[0041] like Figure 1 and Figure 8 As shown, in some embodiments, the installation and disassembly tool further includes a machine tool 5, the machine tool 5 includes a machine tool body 8 and a machine tool ram 7, the machine tool body 8 forms a support surface, the support surface formed by the machine tool body 8 can be used to place the installation frame 6 and the disassembly frame 9, the machine tool ram 7 can apply pressure to the bottom surface of the polygonal wedge 4 through the support block 3 to install the support block 3 in the installation hole 21 of the connecting rod mechanism 2, and the machine tool ram 7 can also apply pressure to the installation shaft 31 of the support block 3 through the polygonal wedge 4 to disassemble the support block 3 installed in the installation hole 21 of the connecting rod mechanism 2. By using a machine tool for installation and disassembly, the efficiency of installation and disassembly can be improved, while reducing the intensity of manual work.

[0042] Using the multi-prism split tip to install and remove the support block and damping set has a better effect. The mechanical analysis diagram is given below. Fig. 9 As shown, the orthogonal method is used for the mechanical analysis of the split tip.

[0043] pressure ,in: , is the friction coefficient between the damping element and the wedge surface of the polygonal pyramid, is the normal elastic force of the splitting surface. This pressure F is the minimum pressure of the machine tool pressure head required for the splitting of the multi-sided table. As the splitting tip goes deeper into the installation hole, the normal elastic force N of the splitting tip surface increases, and the friction force The larger the value, the greater the pressure required; similarly, the tension of the damper against the mounting hole After the support block and the damping sleeve are installed, they will be firmly clamped in the mounting hole of the connecting rod mechanism.

[0044] The installation and disassembly tool of the supporting block of the connecting rod mechanism provided in the embodiment of the present application has the following beneficial effects: when the damping member sleeve of a group of four damping members is placed in the mounting hole of the connecting rod mechanism, the mounting shaft on the supporting block is difficult to be inserted into the mounting hole. Therefore, the multi-sided pyramidal wedge tip can be gradually inserted into the mounting hole by utilizing the plasticity or elasticity of the damping member and the multi-sided pyramidal wedge tip; since the four sides of the multi-sided pyramidal wedge tip are provided with grooves with cylindrical surfaces and an angle β is formed with the side surfaces of the multi-sided pyramidal wedge tip, the damping member and the multi-sided pyramidal wedge tip are firmly clamped during the process of being inserted into the mounting hole, and the tension of the damping member on the surroundings of the mounting hole is gradually increased. Due to the size of the mounting shaft and the bottom surface of the multi-sided pyramidal wedge tip, the multi-sided pyramidal wedge tip is more stable than the multi-sided pyramidal wedge tip. The sizes match, so the connecting rod mechanism support block and the damping member can be smoothly installed in the installation hole; because the mounting frame is designed with a mounting boss, the mounting boss prevents the displacement of the damping member, and the through hole opened in the middle of the mounting boss can make the polygonal wedge tip fall, thereby realizing the installation of the connecting rod mechanism support block; because the mounting frame has a limit screw, the installation position of the connecting rod mechanism can be corrected, which is suitable for batch installation and improves efficiency; in the disassembly of the connecting rod mechanism support block and the damping member, since a disassembly frame matching the support block is designed, the disassembly can be smoothly completed by using any end of the polygonal wedge tip under the action of the machine tool pressure head, and the support block can fall between the support plates to prevent falling and damage, etc. Since the installation and disassembly tooling is targeted and universal, it can be widely used in the field of tobacco machinery.
