Description

Technical Field

[0001] The invention relates to the technical field of track link assembly tooling, and in particular to a spring-type slider tooling of a track link chain pressing machine. Background Art

[0002] The chain press is a special mechanical equipment used for press-fitting and disassembling chain track segments. The press-fitting process is to place the chain track segment on the press-fitting table and adjust it to a suitable press-fitting position, and then use the hydraulic cylinder to apply pressure to the chain track segment. At this time, the chain track segment will gradually deform under the action of pressure and be tightly connected with the axle pin. When the press-fitting displacement reaches the predetermined position, it will stop working and complete the press-fitting process.

[0003] In the process of pressing the chain track segments by the chain press machine, a positioning tool is needed to ensure the stability of the chain track segments during the pressing process, thereby improving the positioning accuracy during the pressing process and ensuring the processing quality; the track segments of the crawler chain are all forgings that have not been finely processed. Without fine processing, the chain track segments have complex and irregular shapes and thickness tolerances. During the assembly process, the chain track segments are pressed by hydraulic cylinders, but the thickness error of the chain track segments will cause problems such as excessive or inadequate pressing, resulting in quality defects in the chain after pressing. The prior art has proposed a good solution to this problem, such as an automatic positioning chain pressing tool with patent publication number CN212886082U, which is designed with a four-claw positioning mechanism and a distance measuring mechanism. The four-claw positioning mechanism is used to accurately position the chain before pressing to ensure the accuracy of pressing; the distance measuring mechanism is used to detect the distance between the detection plate during the pressing process to feedback whether the spacing of the track segments of the crawler chain is appropriate during the pressing process, further improving the processing accuracy.

[0004] Although the existing technology has solved the problem that the hydraulic cylinder pressing distance is fixed and the thickness tolerance of the chain track segment causes quality defects in the chain after press-fitting, the following problems still exist: during the press-fitting process of the traditional tooling, the pin shaft and the chain track segment need to be clamped separately, and the pin shaft is first placed on the positioning tooling in the middle of the press-fitting table, and then the chain track segment is placed on the tooling on both sides of the press-fitting table, and finally the hydraulic cylinder is started for press-fitting; since the chain track segment will warp and deform after quenching, resulting in deviation in the position of the pin hole, when the position of the pin holes of the chain track segments on both sides deviates, on the one hand, it is difficult to place the chain track segment on the tooling, and on the other hand, the pin shaft will have coaxiality errors with the pin holes on the chain track segments on both sides. During the press-fitting process, the coaxiality error will make it more difficult to press-fit the pin shaft and the chain track segment, and when the coaxiality difference is too large, the pin shaft or the chain track segment will be damaged due to excessive stress generated during press-fitting, which will further cause the assembled chain to become loose or damaged.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a spring-type slider tooling for a chain track section chain press. Summary of the invention

[0006] The present invention provides a spring-type slider tooling of a track section chain pressing machine, which solves the problem that it is difficult to place the track section on the positioning tooling when there is a deviation in the pin hole of the track section, and the problem that the coaxiality deviation during the press-fitting process is large, causing the chain to loosen or be crushed. By arranging a positioning mechanism, a vertical compensation mechanism and a correction mechanism, the track sections and the pin shafts on both sides are kept coaxial before press-fitting, and when there is a position deviation in the pin hole of the track section, the positioning mechanism and the vertical compensation mechanism will be offset in the horizontal and vertical directions, and the offsets in the two directions are combined to compensate for the pin hole position deviation, so that the track section can be easily placed on the support block, and when a coaxiality deviation occurs during the press-fitting process, the support block will be subjected to radial force and will generate offset compensation in the vertical and horizontal directions, so that during the press-fitting process, the radial force generated by the deviation can be used to dynamically adjust the overlap of the axes between the two track sections and the pin shafts, to ensure that the coaxiality error after press-fitting is minimized, thereby ensuring the quality of the chain after the press-fitting is completed.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A spring-type slider tooling of a chain track section chain press machine, including a pressing plate and a pin shaft table; also including a positioning mechanism, a vertical compensation mechanism, a correction mechanism and a connecting mechanism; a total of two positioning mechanisms are provided, which are respectively connected to the pressing plates on both sides of the pin shaft table; the vertical compensation mechanism is connected to the positioning mechanism, and when the positioning mechanism is subjected to the radial force squeezed by the pin hole of the chain track section, the vertical compensation mechanism is offset to a position where the chain track section can be smoothly installed on the positioning mechanism; the correction mechanism is arranged between the two positioning mechanisms, and when the positioning mechanism moves horizontally and the vertical compensation mechanism moves vertically, the correction mechanism performs a combined horizontal and vertical movement with the positioning mechanism and the vertical compensation mechanism; the connecting mechanism is connected between the two positioning mechanisms on both sides of the pin shaft table and is connected to the correction mechanism, and when any positioning mechanism and the vertical compensation mechanism are offset under the action of radial force, the connecting mechanism drives the other positioning mechanism and the correction mechanism to move synchronously.

[0009] Preferably, the positioning mechanism includes a positioning guide groove, a main positioning slider, a secondary positioning slider and a tensioning spring; the positioning guide groove is opened on the press plate; the main positioning slider is fixedly mounted on the positioning guide groove; the secondary positioning slider is mounted on the positioning guide groove; the tensioning spring is connected between the main positioning slider and the secondary positioning slider.

[0010] In the above scheme, the two pin holes of the chain track segment are respectively sleeved on the main positioning slider and the auxiliary positioning slider before press-fitting. The two sliders can slide independently so that the chain track segment can be more easily installed on the tooling when there is a deviation in the distance between the two pin holes, thereby avoiding the problem of installation difficulties. When the two pin holes of the chain track segment are sleeved on the main positioning slider and the auxiliary positioning slider, the tensioning spring is not stretched or compressed, and the distance between the two pin holes of the chain track segment is a standard distance without deviation.

[0011] Preferably, the auxiliary positioning slider includes a slider body, a floating groove, a vertical compensation groove and a support block; the slider body is slidably installed in the positioning guide groove; the floating groove is opened on the slider body; the vertical compensation groove is symmetrically opened at the upper and lower ends of the floating groove; the support block is installed in the floating groove, and the radius of the part where the support block is installed in the floating groove is smaller than the radius of the floating groove.

[0012] In the above scheme, by designing the support block connected to the chain track link as a floating structure, the support block can move in the floating groove after being subjected to the radial force from the pin hole of the chain track link during the press-fitting process, thereby driving the vertical compensation mechanism to move, thereby achieving the purpose of vertical offset compensation.

[0013] Preferably, a press-fitting cone surface is provided at the mounting position of the support block and the chain track link pin hole.

[0014] In the above scheme, when there are deviations in the pin holes of the track links on both sides, the pin holes of the track links are squeezed against the press-fitting cone surface during the press-fitting process, which will cause the support block and the slider body to shift under the action of pressure. Dynamic compensation is completed through synthetic motion, so that the track links can undergo micro-deflection, thereby being press-fitted with the minimum coaxiality error to ensure assembly accuracy.

[0015] Preferably, the vertical compensation mechanism includes a vertical pressure groove, a vertical pressure block and a vertical spring, and the vertical pressure groove is symmetrically opened on the upper and lower sides of the auxiliary positioning slider; the vertical pressure block includes a sliding part and an adjusting part; the sliding part is a "mouth"-shaped structure, and its upper and lower ends are respectively slidably installed in the vertical pressure grooves on the upper and lower sides of the auxiliary positioning slider; the adjusting part is slidably installed in the vertical compensation groove, and the radius of the inner wall of the adjusting part is equal to the radius of the part where the support block is installed in the floating groove; the vertical spring is connected between the sliding part and the vertical pressure groove.

[0016] In the above scheme, when deviation occurs in the vertical direction, the chain track pin hole will generate radial pressure on the support block, and the support block will transmit the pressure to the adjustment part. When the adjustment part moves, it will synchronously drive the correction mechanism and the support block on the other side to move together through the connecting mechanism, thereby ensuring that the axis of the chain track pin hole and the axis of the pin shaft on both sides are always kept in the same straight line; and it can cooperate with the tensioning spring and the positioning guide groove to realize adjustment in any direction in the horizontal and vertical directions.

[0017] Preferably, the correction mechanism includes an adjustment groove, a pin shaft seat, a horizontal sliding bolt, a vertical sliding bolt, a horizontal adjustment disc spring group and a vertical adjustment disc spring group; the adjustment groove is arranged on the pin shaft platform, a vertical bolt groove is arranged at the bottom of the adjustment groove, and flat bolt grooves are arranged on both sides of the adjustment groove; the pin shaft seat is slidably installed in the adjustment groove; the horizontal sliding bolt is slidably installed in the flat bolt groove; the vertical sliding bolt is slidably installed in the vertical bolt groove; the horizontal adjustment disc spring group is sleeved on the horizontal sliding bolt and connected to the pin shaft seat; the vertical adjustment disc spring group is sleeved on the vertical sliding bolt and connected to the pin shaft seat.

[0018] When the pin is moved, the pin is driven to move together with it, and the movement of the pin seat makes the axis of the pin and the axis of the auxiliary positioning sliders on both sides reach the position closest to complete overlap, thereby ensuring that the coaxiality deviation of the chain track section and the pin is minimized after press-fitting; since the two pin holes of the chain track section are sleeved on the main positioning slider and the auxiliary positioning slider, the main positioning slider remains stationary, and when there is a position deviation in the pin hole of the chain track section sleeved on the auxiliary positioning slider, radial extrusion will be generated on the auxiliary positioning slider, thereby causing the auxiliary positioning slider to be displaced. When the auxiliary positioning slider is displaced, it will drive the pin seat and the opposite auxiliary positioning slider to move together, so that the axes of the three are always kept in the overlapping position, thereby ensuring that the coaxiality deviation during the press-fitting process is minimized, that is, when the auxiliary positioning slider moves horizontally, vertically or the combined movement of the two, the pin seat will be able to compress the horizontal adjustment disc spring group and the vertical adjustment disc spring group to achieve the purpose of changing the position.

[0019] Preferably, the horizontal adjustment disc spring group and the vertical adjustment disc spring group include multiple disc springs, and two adjacent disc springs are installed in opposite directions.

[0020] In the above scheme, the use of disc springs can control the adjustment range within a smaller range compared to springs, thereby avoiding excessive displacement of the track link, and can ensure that the track link can adjust the pin hole position by rotating at a smaller angle, so that the pin holes on the track links on both sides and the axis of the pin shaft can almost coincide, and the coaxiality error can be compensated by the deformation of the disc spring during the press-fitting process, and the radial force caused by the coaxiality error during the press-fitting process is used to press the disc spring to dynamically adjust the position of the track link and the pin shaft seat to reduce the coaxiality error.

[0021] Preferably, the connecting mechanism includes a vertical drive groove, a horizontal drive groove, a vertical connecting rod and a horizontal connecting rod; the vertical drive groove is opened on the pin shaft seat; the horizontal drive groove is opened on the pin shaft seat; the vertical connecting rod is connected between the two sliding parts, and the middle part of the vertical connecting rod is installed in the vertical drive groove; the horizontal connecting rod is connected between the two auxiliary positioning sliders, and the middle part of the horizontal connecting rod is installed in the horizontal drive groove.

[0022] In the above scheme, the two auxiliary positioning sliders and the pin shaft seats are connected by horizontal connecting rods and vertical connecting rods, so that when one of them moves, the other two can move synchronously, and the two auxiliary positioning sliders and the pin shaft seats can keep the pin hole axes and the pin shaft axes of the two chain track links in a coincident state at all times, thereby maximizing the coaxiality during the press-fitting process.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Compared with the existing positioning tooling, the present invention sets a fixed main positioning slider and a slidable auxiliary positioning slider, and realizes the positioning of the chain track segment through a tensioning spring and a vertical compensation mechanism. It can adapt to the dimensional tolerance of the pin hole of the chain track segment, and can adaptively adapt to the tolerance of the chain track segment for offset compensation when installed on the tooling, thereby facilitating installation and avoiding waste of manpower and reduced efficiency. In addition, the correction mechanism can adjust the axes of the two chain track segments and the pin shaft to the same straight line under ideal conditions, and the correction mechanism and the positioning mechanism can make the chain track segment deflect at a slight angle to achieve the purpose of axis coincidence, thereby ensuring that the subsequent press-fitting process is smoother, the press-fitting accuracy is higher, and the chain quality is guaranteed.

[0025] 2. The present invention connects the correction mechanism and the positioning mechanisms on both sides of the pin shaft table by setting a connecting mechanism, so that the axis of the pin hole of the chain track section installed on the positioning mechanism and the axis of the pin shaft placed on the pin shaft table can always be kept on the same straight line. If the deviation is too large and the chain track section cannot be completely installed to the bottom of the support block, then during the press-fitting process, the chain track section pin hole will be squeezed by the press-fitting cone surface on the support block, generating radial force on the support block. Under the action of the radial force, the auxiliary positioning slider moves horizontally and the support block moves vertically, and the dynamic compensation of the pin hole deviation is achieved through the synthesis of the two, so that the axis of the pin hole of the chain track section on both sides and the axis of the pin shaft can reach the maximum coaxiality that can be achieved during the press-fitting process, thereby ensuring the quality of the pressed chain.

[0026] 3. The present invention provides vertical drive grooves and horizontal drive grooves. When horizontal deviation or vertical deviation is generated and adjusted and compensated, the movement of the horizontal connecting rod and the vertical connecting rod can be synthesized in any direction, thereby ensuring that when the position of the pin hole of the chain track segment on one side deviates, the chain track segments on both sides can achieve the purpose of reducing the coaxiality error through a small angle deflection movement, and micro-adjustment is performed through the disc springs installed in opposite directions. Compared with the coil spring, the use of disc springs can control the adjustment range within a smaller range, thereby avoiding excessive displacement of the chain track segment due to excessive radial force during the press-fitting process, thereby ensuring a smooth press-fitting process and improving the press-fitting accuracy.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 8 The present invention provides a spring-type slider tooling for a chain track section chain press, and the technical solution is as follows:

[0039] As a specific embodiment of the present invention, refer to Figure 1 and Figure 2 , a spring-type slider tooling of a chain track section chain press, comprising a pressing plate 1 and a pin shaft platform 2; further comprising a positioning mechanism 3, a vertical compensation mechanism 4, a correction mechanism 5 and a connecting mechanism 6; a total of two positioning mechanisms 3 are provided, which are respectively connected to the pressing plates 1 on both sides of the pin shaft platform 2; the vertical compensation mechanism 4 is connected to the positioning mechanism 3, and when the positioning mechanism 3 is subjected to the radial force squeezed by the pin hole of the chain track section 7, the vertical compensation mechanism 4 is offset to a position where the chain track section 7 can be smoothly installed on the positioning mechanism 3; the correction mechanism 5 is arranged between the two positioning mechanisms 3, and when the positioning mechanism 3 moves horizontally and the vertical compensation mechanism 4 moves vertically, the correction mechanism 5 moves together with the positioning mechanism 3 and the vertical compensation mechanism 4 in the horizontal and vertical directions; the connecting mechanism 6 is connected between the two positioning mechanisms 3 on both sides of the pin shaft platform 2 and is connected to the correction mechanism 5, and when any positioning mechanism 3 and the vertical compensation mechanism 4 are offset under the action of the radial force, the connecting mechanism 6 drives the other positioning mechanism 3 and the correction mechanism 5 to move synchronously.

[0040] As a specific embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 4The positioning mechanism 3 includes a positioning guide groove 31, a main positioning slider 32, a secondary positioning slider 33 and a tensioning spring 34; the positioning guide groove 31 is provided on the press-fitting plate 1; the main positioning slider 32 is fixedly installed on the positioning guide groove 31, and a protruding limit is provided on the positioning guide groove 31 to limit the main positioning slider 32, so that the main positioning slider 32 cannot move, so that during the press-fitting process, the chain track segment 7 is sleeved on the pin hole of the main positioning slider 32 as a positioning reference for press-fitting; the secondary positioning slider 33 is installed on the positioning guide groove 31; the tensioning spring 34 is connected between the main positioning slider 32 and the secondary positioning slider 33. Before press-fitting, the two pin holes of the track link 7 are respectively sleeved on the main positioning slider 32 and the auxiliary positioning slider 33. The two sliders can slide independently, so that the track link 7 can be more easily installed on the tooling when there is a deviation in the distance between the two pin holes, thereby avoiding the problem of installation difficulties. When the two pin holes of the track link 7 are sleeved on the main positioning slider 32 and the auxiliary positioning slider 33, the tensioning spring 34 is not stretched or compressed, and the distance between the two pin holes of the track link 7 is a standard distance without deviation. The length of the tensioning spring 34 in the undeformed state needs to be selected according to the distance between the two pin holes of the installed track link 7.

[0041] As a specific embodiment of the present invention, refer to Figure 3 and Figure 4 The auxiliary positioning slider 33 includes a slider body 331, a floating groove 332, a vertical compensation groove 333 and a support block 334; the slider body 331 is slidably installed in the positioning guide groove 31; the floating groove 332 is opened on the slider body 331; the vertical compensation groove 333 is symmetrically opened at the upper and lower ends of the floating groove 332; the support block 334 is installed in the floating groove 332, and the radius of the part where the support block 334 is installed in the floating groove 332 is smaller than the radius of the floating groove 332, and the value of the radius of the floating groove 332 being larger than the inner radius of the support block 334 needs to be set within the maximum tolerance range allowed by the pin hole of the chain track link 7. By designing the support block 334 connected to the track link 7 as a floating structure, the support block 334 can move in the floating groove 332 after being subjected to the radial force from the pin hole of the track link 7 during the press-fitting process, thereby driving the vertical compensation mechanism 4 to move, thereby achieving the purpose of vertical offset compensation. In addition, the support block 334 and the slider body 331 are designed separately to ensure that the tensioning spring 34 will not be radially deformed during vertical compensation, thereby ensuring the stability of the press-fitting. At the same time, the radius of the floating groove 332 will also limit the maximum distance of the vertical compensation offset, thereby avoiding the situation where the pin hole position deviation of the track link 7 is too large, and forced press-fitting under compensation causes the pressed-fit chain to have quality defects.

[0042] As a specific embodiment of the present invention, refer to Figure 3, the support block 334 and the pin hole installation position of the track link 7 are provided with a press-fitting cone 3341. When there are deviations in the pin holes of the track links 7 on both sides, the pin holes of the track links 7 are squeezed against the press-fitting cone 3341 during the press-fitting process, which will cause the support block 334 and the slider body 331 to deviate under the action of pressure, and complete dynamic compensation through synthetic motion, so that the track link 7 can be micro-deflected, so that the coaxiality error is minimized during press-fitting, ensuring assembly accuracy; the press-fitting cone 3341 can ensure that the track link 7 cannot be completely installed to the bottom position of the support block 334 due to deviations in the pin holes of the track links 7 on both sides. When the chain link 7 is positioned, during the press-fitting process, one end of the pin hole of the chain link 7 will be squeezed with the pin shaft 8 in the process of being squeezed, so that the other end of the pin hole will be squeezed with the press-fitting cone 3341 on the support block 334, and a radial force will be generated on the support block 334. Under the action of the radial force, the auxiliary positioning slider 33 moves horizontally, and the support block 334 moves vertically, and the dynamic compensation of the pin hole deviation is achieved through the synthesis of the two, so that the pin hole axes of the chain link 7 on both sides and the pin shaft 8 axes can achieve the maximum coaxiality that can be achieved during the press-fitting process, thereby ensuring the quality of the pressed chain.

[0043] As a specific embodiment of the present invention, refer to Figure 3 , Figure 4 and Figure 5 The vertical compensation mechanism 4 includes a vertical pressure groove 41, a vertical pressure block 42 and a vertical spring 43. The vertical pressure groove 41 is symmetrically arranged on the upper and lower sides of the auxiliary positioning slider 33; the vertical pressure block 42 includes a sliding portion 421 and an adjusting portion 422; the sliding portion 421 is a "mouth"-shaped structure, and its upper and lower ends are respectively slidably installed in the vertical pressure groove 41 on the upper and lower sides of the auxiliary positioning slider 33; the adjusting portion 422 is slidably installed in the vertical compensation groove 333, and the inner wall radius of the adjusting portion 422 is equal to the radius of the part where the support block 334 is installed in the floating groove 332; the vertical spring 43 is connected between the sliding portion 421 and the vertical pressure groove 41. When deviation occurs in the vertical direction, the pin hole of the track link 7 will generate radial pressure on the support block 334, and the support block 334 will transmit the pressure to the adjusting part 422. When the adjusting part 422 moves, it will synchronously drive the correction mechanism 5 and the support block 334 on the other side to move together through the connecting mechanism 6, thereby ensuring that the pin hole axis of the track link 7 and the pin shaft 8 on both sides are always kept in the same straight line; and it can cooperate with the tensioning spring 34 and the positioning guide groove 31 to realize adjustment in any direction in the horizontal and vertical directions.

[0044] As a specific embodiment of the present invention, refer to Figure 6 and Figure 7The correction mechanism 5 includes an adjusting groove 51, a pin seat 52, a horizontal sliding bolt 53, a vertical sliding bolt 54, a horizontal adjusting disc spring group 55 and a vertical adjusting disc spring group 56; the adjusting groove 51 is provided on the pin platform 2, a vertical bolt groove 511 is provided at the bottom of the adjusting groove 51, and flat bolt grooves 512 are provided on both sides of the adjusting groove 51; the pin seat 52 is slidably installed in the adjusting groove 51; the horizontal sliding bolt 53 is slidably installed in the flat bolt groove 512; the vertical sliding bolt 54 is slidably installed in the vertical bolt groove 511; the horizontal adjusting disc spring group 55 is sleeved on the horizontal sliding bolt 53 and connected to the pin seat 52; the vertical adjusting disc spring group 56 is sleeved on the vertical sliding bolt 54 and connected to the pin seat 52. During the press-fitting process, the pin 8 is clamped on the pin seat 52. When the pin seat 52 moves, the pin 8 will be driven to move together. The movement of the pin seat 52 makes the axis of the pin 8 and the axis of the auxiliary positioning sliders 33 on both sides reach the position closest to complete overlap, thereby ensuring that the coaxiality deviation of the chain track segment 7 and the pin 8 can be reduced to a minimum after press-fitting; since the two pin holes of the chain track segment 7 are sleeved on the main positioning slider 32 and the auxiliary positioning slider 33, the main positioning slider 32 remains stationary. When there is a position deviation in the pin hole of the chain track segment 7 sleeved on the auxiliary positioning slider 33, radial extrusion will be generated on the auxiliary positioning slider 33, thereby causing the auxiliary positioning slider 33 to be displaced. When the auxiliary positioning slider 33 is displaced, The pin shaft seat 52 and the opposite auxiliary positioning slider 33 are driven to move together, so that the axes of the three are always kept in the overlapping position, thereby ensuring that the coaxiality deviation during the press-fitting process is minimized, that is, when the auxiliary positioning slider 33 performs horizontal movement, vertical movement or combined movement, the pin shaft seat 52 will be able to compress the horizontal adjustment disc spring group 55 and the vertical adjustment disc spring group 56 to achieve the purpose of changing the position; through the horizontal sliding bolt 53 and the vertical sliding bolt 54, on the one hand, the stability of the horizontal adjustment disc spring group 55 and the vertical adjustment disc spring group 56 can be guaranteed, and on the other hand, when the pin shaft seat 52 is offset, it can slide with the pin shaft seat 52 and drive the horizontal adjustment disc spring group 55 and the vertical adjustment disc spring group 56 to move together.

[0045] As a specific embodiment of the present invention, refer to Figure 6 and Figure 7 The horizontal adjustment disc spring group 55 and the vertical adjustment disc spring group 56 include a plurality of disc springs 551, and two adjacent disc springs 551 are installed opposite to each other. Compared with springs, the disc spring 551 can control the adjustment range within a smaller range, thereby avoiding excessive displacement of the track link 7, and can ensure that the track link 7 can adjust the pin hole position by rotating at a smaller angle, so that the pin holes on the track links 7 on both sides and the axis of the pin shaft 8 can almost coincide, and the coaxiality error can be compensated by the deformation of the disc spring during the press-fitting process, and the radial force caused by the coaxiality error during the press-fitting process is used to press the disc spring to dynamically adjust the position of the track link 7 and the pin shaft seat 52, thereby reducing the coaxiality error.

[0046] As a specific embodiment of the present invention, refer to Figure 6 , Figure 7 and Figure 8 The connecting mechanism 6 includes a vertical driving groove 61, a horizontal driving groove 62, a vertical connecting rod 63 and a horizontal connecting rod 64; the vertical driving groove 61 is provided on the pin shaft seat 52; the horizontal driving groove 62 is provided on the pin shaft seat 52; the vertical connecting rod 63 is connected between the two sliding parts 421, and the middle part of the vertical connecting rod 63 is installed in the vertical driving groove 61; the horizontal connecting rod 64 is connected between the two auxiliary positioning sliders 33, and the middle part of the horizontal connecting rod 64 is installed in the horizontal driving groove 62. The two auxiliary positioning sliders 33 and the pin shaft seat 52 are connected by the horizontal connecting rod 64 and the vertical connecting rod 63, so that when one of them moves, the other two can move synchronously, and the two auxiliary positioning sliders 33 and the pin shaft seat 52 can keep the pin hole axes of the two chain track segments 7 and the pin shaft 8 axes in a coincident state, thereby ensuring that the coaxiality can be maximized during the press-fitting process.

[0047] Working process: Place the pin 8 to be installed on the pin seat 52, and then sleeve the pin holes of the two track links 7 on the main positioning slider 32 and the auxiliary positioning slider 33 on both sides of the pin platform 2. When there is a deviation in the pin hole of the track link 7, radial pressure will be generated on the support block 334, thereby triggering the vertical compensation mechanism 4 and the positioning mechanism 3 to compensate in the vertical and horizontal directions, and at the same time drive the correction mechanism 5 to adjust the position of the pin 8 to ensure a smooth press-fitting process. When the track link 7 cannot be completely installed to the bottom of the support block 334, dynamic compensation will be performed during the press-fitting process to minimize the coaxiality error.

[0048] Specifically, after the current pair of track links 7 and pin shafts 8 are press-fitted, a new pin shaft 8 is placed on the pin shaft seat 52 at the rear, and the pin holes of the new pair of track links 7 are sleeved on the main positioning slider 32 and the auxiliary positioning slider 33 on both sides of the pin shaft platform 2. When the pin hole error of the track link 7 is small, the track link 7 can be rotated at a slight angle with the pin hole sleeved on the main positioning slider 32 as the rotation center to make the pin hole axes of the two track links 7 coincide with the pin shaft 8 axes, thereby ensuring the minimum coaxiality deviation during press fitting; when there is a deviation in the pin hole of the track link 7, it will be in the process of installation on the positioning mechanism 3 and during press fitting. During the sliding process, the pin hole of the track link 7 will generate radial pressure on the support block 334. At this time, the support block 334 causes the adjustment portion 422 and the tension spring 34 to be compressed under the radial pressure. At this time, the adjustment portion 422 squeezes the vertical spring 43 to slide vertically, and the slider body 331 will slide horizontally. During the sliding process, the adjustment portion 422 and the slider body 331 will drive the pin shaft seat 52 to move through the vertical connecting rod 63 and the horizontal connecting rod 64 (that is, the vertical connecting rod 63 will generate a lifting force or a lifting force on the vertical driving groove 61 when it moves vertically with the sliding portion 421). The horizontal connecting rod 64 will move horizontally with the auxiliary positioning slider 33, and the horizontal connecting rod 64 will push the pin shaft seat 52 through the horizontal driving groove 62, thereby compressing the disc spring 551 so that the pin shaft seat 52 can move smoothly), and when the two act on the pin shaft seat 52 at the same time, the movement in the direction of the pin hole deviation will be synthesized, so that the axis of the pin shaft seat 52 and the auxiliary positioning sliders 33 on both sides are always kept in the same straight line, thereby ensuring that the coaxiality error is minimized during press fitting; when the pin hole deviation of the chain track segment 7 is too large, resulting in the chain track When the pin hole of section 7 cannot be completely installed to the bottom of the support block 334, during the press-fitting process, one end of the pin hole of the track section 7 will be squeezed with the pin shaft 8, causing the other end of the pin hole to be squeezed with the press-fitting cone 3341 on the support block 334, generating a radial force on the support block 334. Under the action of the radial force, the auxiliary positioning slider 33 moves horizontally, and the support block 334 moves vertically, and the dynamic compensation of the pin hole deviation is achieved through the synthesis of the two, so that the pin hole axes of the track sections 7 on both sides and the pin shaft 8 axes can achieve the maximum coaxiality that can be achieved during the press-fitting process, thereby ensuring the quality of the pressed chain.
