Description

Technical Field

[0001] This utility model relates to the field of track link processing technology, specifically a clamping structure for boring track links. Background Technology

[0002] Track links are crucial components of construction machinery. Drilling and boring are critical steps in track link manufacturing. Track links require drilling on both sides and boring / milling of sleeve holes and shaft holes on both ends. Traditionally, drilling and boring are performed on a single drilling machine followed by boring on a separate boring machine, requiring multiple clamping operations. For example, a track link machining fixture with patent number CN201822247872.4 uses a method of side-mounting and clamping the track link with a cylinder. However, this method has several drawbacks: the cylinder's unfolded placement occupies too much space, making it impossible to clamp multiple track links and reducing boring efficiency; furthermore, the single-sided clamping method makes the track link prone to vibration and displacement during boring, leading to increased hole errors and compromised safety during operation.

[0003] Based on this, the applicant proposes a clamping structure for boring holes in track links. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of existing clamping structures for boring track links, such as the tendency of track links to vibrate and shift due to unilateral clamping, which affects the boring quality and reduces the stability of the track links during clamping. The invention provides a clamping structure for boring track links that is rationally designed, prevents vibration and shifting, produces high-quality boring, maintains high stability during clamping, and ensures good safety during the boring process.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] A clamping structure for boring track links includes an operating table, a support frame, a lower clamping block, and an upper clamping block. A base plate is mounted on the operating table, and a pushing structure is mounted on the base plate. The bottom end of the support frame is movably connected to the pushing structure. A fixed plate and a driving structure are mounted inside the support frame. The pushing structure can move the support frame and the clamped track link, facilitating boring of the clamped track link, improving the stability of the track link during boring, and enhancing the boring quality. After boring, the pushing structure pulls the track link, separating it from the boring equipment for easy removal. This improves both boring efficiency and safety during the boring process. Connecting plates are mounted at both ends of the lower clamping block, and a lower bearing groove is provided on the lower clamping block to connect the upper clamping block. The plate is connected to the drive structure. The upper clamping block has connecting plates at both ends and an upper clamping groove corresponding to the lower bearing groove at the bottom. The connecting plates on the upper clamping block are connected to the drive structure, and a fastening structure is provided in the upper clamping groove. The drive structure can provide power for the lower clamping block and the upper clamping block to move towards each other or away from each other, which facilitates the lower clamping block and the upper clamping block to clamp the track link that needs to be clamped. After the track link is bored, the lower clamping block and the upper clamping block move away from each other, which facilitates the removal of the bored track link from the lower bearing groove on the lower clamping block, improving the efficiency of picking up and putting down the track link. The lower clamping block has two lower bearing grooves and the upper clamping block has two upper clamping grooves, which can clamp and bore two track links on the left and right sides of a set at the same time, improving the processing efficiency of the track link.

[0007] Preferably, the pushing structure includes a hydraulic cylinder and a crossbar. The hydraulic cylinder is mounted on the base plate, and a piston rod is mounted on the hydraulic cylinder. The crossbar is positioned between the base plates. The bottom of the support frame has a through groove through which the crossbar is inserted, connecting the bottom of the support frame to the piston rod. The hydraulic cylinder and piston rod can push the support frame and the clamped track link to move. The support frame moves along the crossbar, causing the clamped track link to contact the boring equipment. This facilitates boring of the clamped track link, improves the stability of the track link during the boring process, and enhances the boring quality of the track link. After the track link is bored, the hydraulic cylinder and piston rod pull the track link to separate it from the boring equipment, making it easy to remove the bored track link. This improves both the boring efficiency and the safety of the track link during the boring process.

[0008] Preferably, the drive structure includes a drive motor, a transmission shaft, and a twin-screw, with the drive motor configured as a servo motor. A bearing is provided on the inner wall of the support frame, and a fixing ring is provided on the fixing plate. The drive motor is mounted on the outer wall of the support frame. One end of the transmission shaft is connected to the drive motor, and the other end is inserted into the bearing. The top end of the twin-screw passes through the fixing ring and is movably connected to the transmission shaft. The drive motor drives the transmission shaft to rotate forward or backward, and the transmission shaft drives the twin-screw to rotate forward or backward, allowing the lower and upper clamping blocks to move towards or away from each other along the twin-screw. This facilitates placing the connecting section requiring boring between the lower and upper clamping blocks or removing the boringed track link from between them, improving work efficiency.

[0009] Preferably, a positioning plate is provided on the inner side wall of the bottom of the support frame, and a bearing is provided on the positioning plate. The bottom end of the double-threaded screw is inserted into the bearing. The positioning plate on the support frame and the bottom end of the positioning plate of the double-threaded screw inserted into the bearing can improve the stability of the double-threaded screw during operation, thereby improving the stability of the clamped track link.

[0010] Preferably, a bevel gear one is provided on the drive shaft, and a bevel gear two is provided at the top of the double-threaded screw. The bevel gear one and the bevel gear two are meshed and connected. The drive motor drives the drive shaft and the bevel gear one on the drive shaft to rotate in the forward or reverse direction. The bevel gear one drives the bevel gear two and the double-threaded screw to rotate in the forward or reverse direction, so that the lower clamping block and the upper clamping block can move towards each other or away from each other along the double-threaded screw. This makes it convenient to put the connecting section that needs to be bored between the lower clamping block and the upper clamping block, or to take out the boring track section from between the lower clamping block and the upper clamping block, thereby improving work efficiency.

[0011] Preferably, connecting screws are provided on the connecting plates on both sides of the lower clamping block and the upper clamping block, and the connecting screws are sleeved on the double-threaded screw. During the forward or reverse rotation, the double-threaded screw pushes the connecting screws to rise or fall along the double-threaded screw, causing the lower clamping block and the upper clamping block to move towards each other or away from each other, which facilitates the picking and putting away of the chain link. In order to further improve the versatility of the clamping structure, the connecting plate and the lower clamping block and the connecting plate and the upper clamping block can also be connected by threads, so that the lower clamping block and the upper clamping block can be replaced according to different specifications of chain links, which not only improves the stability of the chain link during the clamping process, but also improves the versatility of the clamping structure.

[0012] Preferably, the fastening structure includes a fastening plate. A fixing groove is provided on the upper clamping block at the top of the upper clamping groove. A connecting post is provided on the fastening plate. The top of the connecting post extends into the fixing groove, and a spring is provided between the top of the fixing groove and the connecting post. The chain link to be clamped is placed into the lower bearing groove on the lower clamping block. The lower clamping block pushes the chain link upward, and the upper clamping block moves downward to clamp the chain link. The chain link pushes the fastening plate upward, and the chain link on the fastening plate compresses the spring upward. The compressed spring pushes the connecting post in the opposite direction, and the connecting post pushes the fastening plate downward, thus clamping the chain link and further improving the stability of the chain link during clamping.

[0013] Preferably, the bottom of the fastening plate is provided with an anti-slip pad. The anti-slip pad can prevent the track link from sliding during the clamping process, thereby enhancing the clamping effect of the track link. On the other hand, the anti-slip pad can prevent the track link from making hard contact with the fastening plate, thus preventing damage to the surface of the track link during the clamping process and improving the integrity of the track link.

[0014] Beneficial effects:

[0015] 1. The hydraulic cylinder and piston rod can push the support frame and the clamped track link to move. The support frame moves along the crossbar to bring the clamped track link into contact with the boring equipment, which facilitates the boring process of the clamped track link, improves the stability of the track link during the boring process, and enhances the boring quality of the track link. After the track link is bored, the hydraulic cylinder and piston rod pull the track link to separate the track link from the boring equipment, which makes it easy to remove the bored track link. This can improve the boring efficiency of the track link and the safety of the track link during the boring process.

[0016] 2. The drive motor drives the transmission shaft and the first bevel gear on the transmission shaft to rotate in the forward or reverse direction. The first bevel gear drives the second bevel gear and the double screw to rotate in the forward or reverse direction, so that the lower clamping block and the upper clamping block can move towards each other or away from each other along the double screw. This makes it convenient to put the connecting section that needs to be bored between the lower clamping block and the upper clamping block, or to take out the boring track section from between the lower clamping block and the upper clamping block, thus improving work efficiency.

[0017] 3. Place the track link to be clamped into the lower bearing groove on the lower clamping block. The lower clamping block pushes the track link upward, and the upper clamping block moves downward to clamp the track link. The track link pushes the fastening plate upward, and the track link on the fastening plate squeezes the spring upward. The compressed spring pushes the connecting post in the opposite direction, and the connecting post pushes the fastening plate downward, so that the fastening plate clamps the track link, further improving the stability of the track link during the clamping process.

[0033] Example 2:

[0034] Further explanation is provided based on Example 1, as shown in the appendix. Figure 6-7As shown, a push rod 29 is provided on the operating table 1, and a through hole 30 is provided on the lower clamping block 3. After the clamped track link is bored, the hydraulic cylinder 7 and piston rod 8 pull the support frame 2 to move, moving the bored track link above the push rod 29. The drive motor 15 drives the transmission shaft 16 and the bevel gear 18 on the transmission shaft 16 to rotate. The bevel gear 18 drives the double screw 17 to rotate through the bevel gear 19, causing the lower clamping block 3 to lower the track link. The push rod 29 enters the through hole 30, pushing the track link placed in the lower support groove 21 upward, so that the track link is moved out of the lower support groove 21, making it easier for the operator to remove the bored track link and improving the material unloading efficiency of the track link.

[0035] Working principle: The bottom of the track link requiring boring is placed in the lower bearing groove 21 on the lower clamping block 3. The drive motor 15 is started, which drives the transmission shaft 16 and the first bevel gear 18 on the transmission shaft 16 to rotate in the forward direction. The first bevel gear 18 drives the second bevel gear 19 and the double screw 17 to rotate in the forward direction, so that the lower clamping block 3 and the upper clamping block 4 can move towards each other along the double screw 17, so that the lower clamping block 3 and the upper clamping block 4 clamp the track link from the upper and lower sides. The track link pushes the fastening plate 24 upward, and the track link on the fastening plate 24 compresses the spring 27 upward. The compressed spring 27 pushes the connecting column 26 in the reverse direction, and the connecting column 26 pushes the fastening plate 24 downward, so that the fastening plate 24 clamps the track link. After the track link is clamped, the hydraulic cylinder 7 is started. The hydraulic cylinder 7 and the piston The rod 8 can push the support frame 2 and the clamped track link to move. The support frame 2 moves along the crossbar 6 to move the clamped track link, so that the track link comes into contact with the boring equipment, which facilitates the boring process of the clamped track link. After the track link is bored, the hydraulic cylinder 7 is started. The hydraulic cylinder 7 and the piston rod 8 pull the track link to separate the track link from the boring equipment.
