DETAILED DESCRIPTION

[0030] The present application will be further described below in conjunction with the drawings and examples. The examples described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0031] As attached Figures 1-9As shown, a shock absorber clamping positioning tool includes a base 1, a positioning boss 2, a limiting block 3 and a support 4 are fixedly connected to the top surface of the base 1, and the limiting block 3 and the support 4 are located on both sides of the positioning boss 2 in the horizontal direction; the top surface of the base 1 is a limiting plane; further including an adapter block 5 fixedly connected to the top surface of the base 1 and a positioning pin 6 installed on the adapter block 5; the adapter block 5 is provided with a plug-in hole 51 with an opening facing upward and a first positioning hole 52 perpendicular to the plug-in hole 51, and the first positioning hole 52 and the plug-in hole 51 are in communication; the limiting block 3 is provided with a lower convex plug-in part 33 and an axial limiting part 34 protruding from the side wall of the plug-in part 33, the plug-in part 33 is plugged into the plug-in hole 51, and the lower end surface of the axial limiting part 34 is fitted with the upper surface of the adapter block 5; the plug-in part 33 is provided with a second positioning hole 31; the positioning pin 6 is plugged into the first positioning hole 52 and the second positioning hole 31; the support 4 and the adapter block 5 are adjustable in position in the radial direction of the positioning boss 2; and the positioning boss 2 is detachably installed on the base 1.

[0032] The plug-in part 33 and the plug-in hole 51 cooperate to position the limiting block 3 in the horizontal direction; the positioning pin 6 is plugged into the first positioning hole 52 to position the positioning pin 6 radially, the positioning pin 6 is plugged into the second positioning hole 31 and cooperates with the second positioning hole 31 to position the plug-in part 33 and the limiting block 3 in the upward and downward directions, thereby positioning and installing the limiting block 3 on the adapter block 5. Pulling out the positioning pin 6 from the second positioning hole 31 can release the axial positioning of the plug-in part 33 and the limiting block 3, and then the limiting block 3 can be quickly assembled and disassembled by plugging and pulling. During the process of plugging and installing the limiting block 3, the axial limiting part 34 is fitted with the upper surface of the adapter block 5 to limit its axial direction, ensuring that the second positioning hole 31 on the plug-in part 33 is coaxial with the positioning pin 6 in the first positioning hole 52, facilitating the accurate insertion of the positioning pin 6 into the second positioning hole 31 to quickly position the limiting block.

[0033] The shape and size of the positioning boss 2 and the circular groove on the bottom surface of the damper 91 are matched, and the shape and size of the limiting block 3 and the U-shaped clamping groove on the U-shaped piece 93 are matched. When the damper assembly structure is clamped on the positioning tool of the utility model, the top surface of the base 1 supports the damper assembly structure to limit it in the axial direction of the damper 91; the positioning boss 2 is inserted into the circular groove on the bottom surface of the damper 91 to position the damper 91 in the horizontal radial direction; the limiting block 3 is clamped in the U-shaped clamping groove of the U-shaped piece 93 and is in close contact with the two side walls of the U-shaped clamping groove to position the U-shaped piece 93 in the direction perpendicular to the two side walls of the U-shaped clamping groove, so as to avoid that the U-shaped piece 93 drives the entire damper assembly structure to rotate around the positioning boss 2; the limiting block 3 supports the bottom wall of the U-shaped clamping groove of the U-shaped piece 93, and the supporting piece 4 supports the outer wall of the sleeve 92, and the limiting block 3 and the supporting piece 4 cooperate to support and position the entire damper assembly structure, so as to ensure that the axis of the damper 91 is arranged in the up-down direction and improve the clamping reliability.

[0034] During the assembly operation of the damper 91, the base 1 installs the entire positioning tool and the damper 91 on the conveying line and synchronously moves with the conveying line. The positioning tool of the utility model can position the damper 91 in the horizontal radial direction by replacing the positioning boss 2 with different structures on the circular groove on the bottom surface of the damper 91 with different specifications; the U-shaped piece 93 with different structures is replaced by replacing the limiting block 3 with different structures to adapt to the U-shaped piece 93 and the entire damper assembly structure to be positioned in the circumferential direction relative to the positioning boss 2; the damper 91 with different outer diameters is supported and positioned by adjusting the radial position of the supporting piece 4 relative to the positioning boss 2 and adjusting the radial position of the adapter block 5 relative to the positioning boss 2. That is, the positioning tool of the utility model can clamp and position the damper assembly structure with different specifications of the damper 91 by replacing the positioning boss 2, the limiting block 3, the horizontal position of the supporting piece 4 and the adapter block 5, without replacing the entire positioning tool, improving the efficiency of line change, saving manpower and improving the flexibility of the entire assembly line; without preparing multiple positioning tools with different specifications, saving costs. In addition, the second positioning hole 31 and the first positioning hole 52 are quickly aligned and communicated by positioning the limiting block 3 in the horizontal direction through the insertion hole 51 and limiting the limiting block 3 in the up-down direction through the axial limiting part 34 on the limiting block 3; the insertion part 33 and the limiting block 3 are quickly positioned and installed on the adapter block 5 by using the positioning pin 6, thereby improving the disassembly and assembly efficiency of the limiting block 3.

[0035] The base 1 is used for supporting the damper assembly structure to position and install the whole clamping positioning tool and the damper assembly structure thereon on the conveying line. The base 1 can be a frame structure welded by channel steel, steel pipe and the like steel materials, but the structure is not easy to guarantee the flatness of the base 1 and is complex. In order to guarantee the positioning accuracy of the damper 91, the base 1 generally adopts a steel plate structure, which is simple in structure and convenient for processing and manufacturing. The positioning boss 2 is used for horizontally and radially positioning the damper 91 on the base 1. The positioning boss 2 and the base 1 can be mutually inserted or threadedly connected, and can also be connected through a connecting piece such as a pin or a bolt. Specifically, the positioning boss 2 and the base 1 are tightly connected through a first fastening bolt 21, and the center line of the first fastening bolt 21 is arranged in the up-down direction, so as to facilitate the assembly and disassembly of the positioning boss 2. The cross section of the positioning boss 2 is generally a cylindrical structure matched with the circular groove shape and size of the bottom surface of the damper 91, and the positioning boss 2 of the cylindrical structure is easy to slide during clamping and screwing, and is inconvenient to assemble and disassemble. Preferably, the side wall of the upper part of the positioning boss 2 comprises two mutually parallel clamping planes, and the two planes on the clamping side wall are used to screw the positioning boss 2 when the positioning boss 2 is assembled and disassembled, so as to be labor-saving and improve the assembly and disassembly efficiency.

[0036] During the assembly of the damper 91, the positioning boss 2 is inserted into the circular groove in the bottom surface of the damper 91, and the damper 91 will exert a certain pressure on the side wall of the positioning boss 2 after being stressed, which is easy to cause the first fastening bolt 21 to be bent and deformed, thereby affecting the positioning accuracy. Preferably, a positioning groove 11 is arranged on the top surface of the base 1, and the lower part of the positioning boss 2 is inserted into the positioning groove 11; and the side wall of the positioning groove 11 is in close contact with the side wall of the positioning boss 2. The side wall of the positioning groove 11 not only positions the positioning boss 2 in the horizontal direction, but also supports the positioning boss 2 when the side wall of the positioning boss 2 is pressed, thereby sharing the pressure received by the first fastening bolt 21, avoiding the deformation of the first fastening bolt 21, guaranteeing the installation accuracy and reliability of the positioning boss 2, and further improving the clamping positioning accuracy of the damper 91.

[0037] The limiting block 3 is used for positioning the U-shaped piece 93 in the circumferential direction of the positioning boss 2, and the limiting block 3 is in close contact with the bottom wall and the side wall of the U-shaped clamping groove on the U-shaped piece 93 during use. The limiting block 3 can be a column structure, a cylindrical structure or a frame structure, etc. The insertion part 33 can be a column structure, a table structure or a conical structure, etc., and the cross section thereof can be circular, elliptical or rectangular structure, etc. Preferably, the insertion part 33 is a prismatic structure, and the shapes and sizes of the insertion hole 51 and the insertion part 33 are matched. That is, the side wall of the insertion hole 51 is in close contact with the side wall of the insertion part 33 to horizontally position the side walls of the insertion part 33 and the limiting block 3, so as to position the limiting surface on the limiting block 3 in close contact with the inner wall of the U-shaped piece 93 to quickly position the limiting surface on the limiting block 3.

[0038] The axial limiting part 34 is used to ensure the axial installation precision of the limiting block 3, and quickly align the second positioning hole 31 with the first positioning hole 52. The axial limiting part 34 can be a single protruding structure, or a plurality of protruding structures arranged circumferentially along the plug-in part 33; the axial limiting part 34 can be arranged on the plug-in part 33 or the limiting block 3. Preferably, the limiting block 3 protrudes from the outer wall of the plug-in part 33, and the bottom surface of the limiting block 3 is the axial limiting part 34, which is simple in structure and convenient to process.

[0039] The support 4 is used to support the side wall of the damper combination structure, and the adapter block 5 is used to connect the limiting block 3 to the base 1. The support 4 and the adapter block 5 can be of any shape, such as a cuboid, a cylinder, a sphere, etc. The support 4 and the adapter block 5 can be slidingly fitted with the base plate 1 along the horizontal depth direction of the groove on the U-shaped block 3, and are fixed in position by a latch, a bolt block, etc. Specifically, the side wall of the support 4 close to the limiting block 3 is a support surface 41; the support 4 is provided with a first strip-shaped hole 42 penetrating in the up-down direction, and the length direction of the first strip-shaped hole 42 is perpendicular to the support surface 41; the strip-shaped hole 42 is provided with a second fastening bolt 43 threadedly connected with the base 1, and the support 4 is tightly connected with the base 1 by the second fastening bolt 43. Since the limiting block 3 is installed on the adapter block 5, it is not convenient to arrange a strip-shaped hole on the adapter block 5. Therefore, the base 1 is provided with a second strip-shaped hole 12 penetrating in the up-down direction, and the length direction of the second strip-shaped hole 12 is perpendicular to the support surface 41; the second strip-shaped hole 12 is provided with a third fastening bolt 15 threadedly connected with the adapter block 5, and the adapter block 5 is tightly connected with the base 1 by the third fastening bolt 15.

[0040] The adapter block 5 is used to connect the limiting block 3 to the base 1, and the horizontal position of the limiting block 3 is adjusted by adjusting the position of the adapter block 5 on the base 1. The first positioning hole 52 is used to position the positioning pin 6, and the second positioning hole 31 cooperates with the positioning pin 6 to realize the positioning of the limiting block 3 in the up-down direction. The hole diameter of the first positioning hole 52 is greater than or equal to the hole diameter of the second positioning hole 31. The positioning pin 6 can be a light shaft structure or a stepped shaft structure. When the positioning pin 6 is pulled out of the second positioning hole 31, it is easy to fall off and be lost from the first positioning hole 52. Preferably, the positioning pin 6 comprises a first pin segment 61 and a second pin segment 62 arranged axially adjacent and coaxially, and further comprises an axial limiting portion 63 protruding from the outer wall of the first pin segment 61 and a second protruding portion 64 protruding from the side wall of the second pin segment 62; the first pin segment 61 is inserted into the second positioning hole 31, the second pin segment 62, the axial limiting portion 63 and the second protruding portion 64 are all located in the first positioning hole 52, and the end of the second pin segment 62 away from the first pin segment 61 protrudes out of the first positioning hole 52; the axial limiting portion 63 abuts against the outer wall of the insertion portion 33; the opening end of the first positioning hole 52 is provided with a first protruding portion 53 protruding radially inwardly; the first positioning hole 52 is provided with a compression elastic member 65, one end of the compression elastic member 65 abuts against the second protruding portion 64, and the other end of the compression elastic member 65 abuts against the first protruding portion 53. When replacing the limiting block 3, the second pin segment 62 is pulled horizontally outwardly to make the first pin segment 61 come out of the second positioning hole 31, thereby releasing the positioning of the limiting block 3 and keeping the original limiting block 3. After the original limiting block 3 is pulled out of the insertion hole 51, the new limiting block 3 is inserted into the insertion hole 51 and the lower end surface of the limiting block 3 abuts against the upper surface of the adapter block 5, and finally the second pin segment 62 is loosened. The compression elastic member 65 automatically rebounds and pushes the second protruding portion 64 and the entire positioning pin 6 to quickly reset, the first pin segment 61 is reset and inserted into the second positioning hole 31 to position the limiting block 3, thereby saving manpower and further improving the disassembly efficiency of the limiting block 3. At the same time, the compression elastic member 65 is always in a compressed state and abuts tightly against the second protruding portion 64, thereby avoiding the positioning pin 6 from falling off. A limiting boss can also be arranged on the hole wall of the first positioning hole 52, and the axial limiting portion 63 abuts against the limiting step to realize the axial positioning of the positioning pin 6.

[0041] As a further preferred, the first pin segment 61 is coaxially provided with a ring plate protruding from the side wall of the first pin segment 61 and the side wall of the second pin segment 62, the outer contour of the cross section of the ring plate is matched with the shape and size of the first positioning hole 52; the ring plate is the second protruding part 64, and the end face of the ring plate away from the second pin segment 62 is the axial limiting part 63. In order to simplify the structure of the positioning pin 6 and save production cost. The outer contour of the cross section of the ring plate is matched with the shape and size of the first positioning hole 52 means that the side wall of the first positioning hole 52 is in close contact with the side wall of the ring plate and the ring plate and the positioning pin 6 are radially positioned.

[0042] The compression elastic member 65 can be a strip-shaped elastic member, which can be provided with one or a plurality of strip-shaped elastic members along the circumference of the second pin segment 62, but the compression elastic member 65 of the structure is easy to slide in the first positioning hole 52 after being compressed, and is not convenient to assemble. Preferably, the compression elastic member 65 is a compression elastic sleeve which is sleeved on the second pin segment 62, and the second pin segment 62 limits the radial position of the compression elastic sleeve, which is simple in structure and convenient to assemble. The compression elastic sleeve can be an elastic rubber sleeve or a compression spring.

[0043] In order to facilitate pulling the positioning pin 6, a pull handle structure can be provided on the end of the second pin segment 62 extending out of the first positioning hole 52.
