[0002] Track links are widely used in crawler chassis of construction machinery such as excavators and bulldozers. They are components that connect the track plates for transmission and serve as the forward track of the supporting wheels. At present, track links are mainly produced by forging. The production of track link forgings mainly goes through flattening, pre-forging, final forging... trimming, punching, correction and other processes.

They do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present application.

[0019] At present, the track link is mainly produced by forging, and the production of the track link forging mainly goes through multiple processes such as flattening, pre-forging, final forging, trimming and punching, and correction. Among them, the track link mold 300 includes a push rod seat 330, a push rod 320 fixed on the push rod seat 330, and a compression spring 310 and a push rod collar 340 sleeved on the push rod 320. The push rod 320 is provided with a pin hole, and the push rod collar 340 is provided with a pin mounting hole 350 corresponding to the pin hole. During assembly, after the compression spring 310 and the push rod collar 340 are sleeved on the push rod 320 in sequence, the push rod collar 340 is pushed to compress the compression spring 310. When the pin mounting hole 350 on the push rod collar 340 coincides with the pin hole on the push rod 320, a pin is inserted therein, so that the compression spring 310 is assembled between the push rod collar 340 and the push rod seat 330. Since springs generate a certain resistance when compressed, they face certain challenges during assembly. Especially in the step of fixing the cylindrical pin, two operators are usually required to work together to ensure safe completion. However, the rebound characteristics of springs increase the risk of assembly, resulting in low efficiency of assembly work and even potential safety hazards.

[0020] refer to Figures 1 to 4 As shown, the present application discloses a chain track segment mold assembly tool, including a fixing device 100 and a spiral device 200 spirally connected to the fixing device 100 for compressing a compression spring 310, the fixing device 100 includes an open frame structure composed of a top plate 110 and a clamping plate 120, and a accommodating space for accommodating the chain track segment mold 300 and the spiral device 200 is provided in the middle of the frame structure, a spiral block 130 is fixed to the top of the top plate 110, the spiral device 200 includes a screw rod 220 spirally connected to the spiral block 130, the screw rod 220 is parallel to the axis of the clamping plate 120, the end of the screw rod 220 close to the accommodating space is connected to the propulsion assembly 230, and the end of the screw rod 220 away from the accommodating space is connected to the handle 210.

[0021] The chain track segment mold assembly tool of this embodiment can compress the compression spring 310 to a predetermined state by screwing the handle 210, which drives the screw 220 to rotate and pushes the propulsion assembly 230 to move axially along the clamping plate 120, so that the pin shaft mounting hole 350 on the push rod collar 340 coincides with the pin shaft hole on the push rod 320, and then the pin shaft is inserted into the pin shaft hole to complete the assembly of the chain track segment mold 300. In this process, the spiral connection has a locking function. When the worker inserts the pin shaft, the compression spring 310 will not rebound even if the worker leaves the handle 1 with both hands; the traditional assembly method usually requires two operators to work together and faces the risk of spring rebound; the present tool realizes the compression of the compression spring 310 through the spiral device 200, and a single person can complete the assembly independently, which greatly improves the assembly efficiency.

[0022] In some embodiments, the propulsion assembly 230 is rotatably connected to the screw rod 220, and the propulsion assembly 230 includes a limit plate 231 slidably connected to the clamp plate 120 and a top barrel 232 fixed to the side of the limit plate 231 away from the screw rod 220. Specifically, both ends of the limit plate 231 are provided with a slot matching the shape of the clamp plate 120, and the limit plate 231 is slidably connected to the clamp plate 120 through the slot. The propulsion assembly 230 can only move along the axial direction of the clamp plate 120, and cannot be lateral offset, thereby ensuring the stability of the propulsion assembly 230 during movement.

[0023] In some embodiments, a through hole is provided in the middle of the limit plate 231 for the screw 220 to pass through, the limit plate 231 is fixedly connected to the top barrel 232 by means of screws 400, a second groove is provided at one end of the top barrel 232 close to the limit plate 231, a push block 233 rotatably connected thereto is provided in the second groove, and the screw 220 is fixedly connected to the push block 233 after passing through the through hole on the limit plate 231. When the handle 210 is screwed, the handle 210 drives the screw 220 to rotate, the screw 220 moves along its axial direction under the spiral cooperation of the spiral block 130, and the screw 220 drives the push block 233 to rotate and pushes the propulsion assembly 230 to move.

[0024] In the above embodiment, there are many options for the specific arrangement of the push block 233. For example, the push block 233 is cylindrical, the first groove is a cylindrical groove corresponding to the push block 233, and one end of the push block 233 is connected to the screw rod 220 by a threaded connection or a key connection, so as to be fixedly connected to the end of the screw rod 220 and ensure that the torque can be smoothly transmitted during the rotation process. The other end of the push block 233 is a plane or a slightly curved surface, which serves as a push surface in contact with the top barrel 232. This structure can ensure that when the push block 233 rotates, the top barrel 232 can be smoothly pushed to move along the axial direction of the clamping plate 120. Furthermore, a plane bearing is provided between the push surface of the push block 233 and the bottom surface of the second groove. The plane bearing can reduce the friction and wear of the push block 233 during the rotation process, which can not only improve the rotation flexibility of the push block 233, but also extend its service life.

[0025] In some embodiments, one end of the top barrel 232 away from the limiting plate 231 is provided with a first groove arranged along its axial direction, and the shape and size of the first groove match the shape and size of the top rod 320 on the track segment mold 300, so that when the side wall of the top barrel 232 abuts against the top rod collar 340 and pushes the compression spring 310 to compress, the top rod 320 can extend into the first groove in the middle of the end of the top barrel 232, so that the pin shaft mounting hole 350 on the top rod collar 340 coincides with the pin shaft hole on the top rod 320. In this embodiment, the first groove is a cylindrical slot with a depth of 30 mm, and its diameter is larger than the diameter of the top rod 320.

[0026] In some embodiments, a cushion block 140 for supporting the track segment mold 300 is provided at the bottom of the accommodating space, and the cushion block 140 is fixedly connected to the fixing device 100 via screws 400 .

[0027] In some embodiments, the spiral block 130 includes a first spiral block and a second spiral block symmetrically arranged and slidingly connected to the top plate 110, and the first spiral block and the second spiral block are respectively provided with a first threaded arc surface and a second threaded arc surface on the opposite sides. When the first spiral block and the second spiral block are engaged together, the first threaded arc surface and the second threaded arc surface enclose a threaded hole that is spirally connected to the screw rod 220.

[0028] Furthermore, the top plate 110 is provided with a guide rail for sliding connection with the first spiral block and the second spiral block. Preferably, the guide rail is an inverted trapezoidal guide rail, and the bottom of the first spiral block and the second spiral block is provided with an inverted trapezoidal guide groove corresponding to the inverted trapezoidal guide rail, which ensures that the spiral block will not fall off the guide rail during movement, thereby improving the stability and safety of the connection. The guide rail is provided with a positioning hole and a latch matched with the positioning hole. When in use, after the first spiral block and the second spiral block are moved to a predetermined position, the latch is inserted into the positioning hole to limit the movement of the first spiral block and the second spiral block, so as to realize the connection between the spiral block 130 and the screw rod 220. After use, the latch is pulled out of the positioning hole, so that the spiral block 130 is out of contact with the screw rod 220, so that the screw rod 220 can move quickly along the axial direction of the clamping plate 120, and no longer needs to move spirally along the spiral block 130, which saves time for reassembling the remaining chain track segment molds 300 and improves work efficiency.

[0029] Instructions for use: After sequentially sleeve the compression spring 310 and the push rod collar 340 on the push rod 320, place the track segment mold 300 into the accommodating space of the track segment mold assembly tooling; fix the cushion block 140 at the bottom of the accommodating space with the screw 400, the cushion block 140 is used to support the push rod seat 330, so that the splints on both sides of the push rod seat 300 are suspended; turn the handle 1, the top barrel 232 pushes the push rod collar 340 to compress the compression spring 310; when the pin shaft mounting hole 350 on the push rod collar 340 coincides with the pin shaft hole on the push rod 320, insert the pin shaft therein, so that the compression spring 310 is assembled between the push rod collar 340 and the push rod seat 330.
