Description

Technical Field

[0001] The utility model relates to the technical field of track iron tooth production, in particular to a track iron tooth post-forming trimming device. Background Art

[0002] The iron teeth are deeply buried and bonded inside the rubber track, acting as a supporting skeleton. They are metal components that directly mesh with the machine driving wheel to transmit power and support the weight of the machine. At present, in order to enhance the strength of the skeleton, rubber tracks are buried with circumferential steel wires, and iron teeth are buried at a certain distance. The iron teeth cooperate with the load-bearing wheels to realize the transmission of the track. The existing iron teeth are generally composed of a bridge section, a wing plate, and a guide block.

[0003] After the track teeth are formed, their sides need to be trimmed. Usually, the track teeth are manually ground, which is time-consuming and labor-intensive in large-scale production. In addition, workers are prone to negligence and bruises during long hours of work, which is not conducive to processing and production. Utility Model Content

[0006] By adopting the above technical solution, the automatic trimming of the track teeth can be achieved, which saves manpower and avoids accidental abrasions caused by workers grinding the track teeth for a long time.

[0007] The grinding mechanism is arranged on both sides of the displacement mechanism, and comprises an electric cylinder and a grinder. The electric cylinder is fixed on the workbench through a mounting seat, and the grinder slides along the mounting seat through a base and is fixedly connected to the output end of the electric cylinder.

[0008] By adopting the above technical solution, the track teeth are ground.

[0014] By adopting the above technical solution, it is convenient for the staff to manually adjust the bolt position on the stud to limit the limit plate.

[0015] The beneficial effects of the track iron tooth trimming device after forming are:

[0016] According to the size of the track teeth, the positions of the two groups of limit seats are first adjusted, and the track teeth are placed upside down on the limit seats. The two ends are supported by support plates, and then the cylinder is driven to apply pressure to the ends of the track teeth through the pressure plate. After the upper end of the limit plate extends from the movable plate, the bottom of the limit plate is limited to complete the side position limit of the track teeth. The electric push rod is started to pull the movable plate through the bottom plate to slide along the workbench, and the track teeth can be gradually trimmed by the grinder. During this period, the electric cylinder can be started to push the manual grinder to approach the track teeth until the side of the track teeth reaches the trimming standard, thereby realizing automatic trimming of the track teeth, saving manpower, and avoiding accidental physical abrasions caused by long-term hand-held track teeth grinding by the staff.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Reference Figure 1-3 A post-forming trimming device for track teeth comprises a workbench 1 and a shifting mechanism and a grinding mechanism installed on the workbench 1. The shifting mechanism comprises an electric push rod 2, a moving plate 3, a cylinder 4, a limiting plate 5, a stud 6, a support plate 7, a screw 8 and a limiting seat 9. The moving plate 3 is located at the slide groove of the workbench 1 and is pulled by the electric push rod 2 to slide along the workbench 1. The cylinder 4 is divided into two groups and is oppositely arranged on the moving plate 3. The support plate 7 is divided into two groups and is located between the two groups of cylinders 4. The screw 8 is fixed between the two groups of support plates 7. The limiting seat 9 is divided into two groups and slides along the screw 8 and the workbench 1. The limiting plate 5 is arranged through the moving plate 3 and slides along the stud 6 fixed at the bottom of the moving plate 3 and is locked by bolts.

[0023] According to the size of the track teeth 12, the positions of the two groups of limit seats 9 are first adjusted, and then the two sides of the two groups of limit seats 9 are limited by bolts respectively, and the limit seats 9 are positioned on the screw rod 8. Then, the track teeth 12 are correspondingly placed upside down on the limit seats 9, and the two ends of the track teeth 12 are supported by the support plates 7, and then the cylinder 4 is driven to apply pressure to the ends of the track teeth 12 through the pressure plate 401. At this time, the limit plate 5 is pushed upward along the stud 6, so that the upper end of the limit plate 5 extends from the movable plate 3 until its inner side surface contacts the tooth side of the track teeth 12, and then the bolts on the stud 6 can be rotated to limit the bottom of the limit plate 5, so that the limit plate 5 is kept in this position, that is, the side position of the track teeth 12 is limited;

[0024] The grinding mechanism is arranged on both sides of the shifting mechanism, including an electric cylinder 10 and a grinder 11. The electric cylinder 10 is fixed on the workbench 1 through a mounting seat, and the grinder 11 slides along the mounting seat through a base and is fixedly connected to the output end of the electric cylinder 10; then the grinder 11 is driven, and the electric push rod 2 is started to pull the moving plate 3 to slide along the workbench 1 through the bottom plate 301, and the track teeth 12 can be gradually trimmed by the grinder 11. During this period, the electric cylinder 10 can be started to push the manual grinder 11 to approach the track teeth 12 until the side of the track teeth 12 reaches the trimming standard.

[0025] The limiting plate 5 is a rectangular parallelepiped with an inverted trapezoidal groove in the middle thereof. The two side edges of the limiting plate 5 pass through the movable plate 3 and are located on both sides of the screw rod 8 respectively. The movable plate 3 is provided with two notches which are suitable for the side edges of the limiting plate 5. The side edges of the limiting plate 5 can pass through the notches, and the bottom of the limiting plate 5 is below the movable plate 3. There are two studs 6 installed at the bottom of the movable plate 3 and pass through the bottom of the movable plate 3. After the limiting plate 5 is adjusted to a good position, the nuts on the studs 6 can be rotated to limit the limiting plate 5 from moving downward.

[0026] A pressure plate 401 is provided at the output end of the cylinder 4, and the pressure plate 401 is horizontally arranged and parallel to the upper end surface of the support plate 7; after the track teeth 12 are placed on the limit seat 9, the two ends of the track teeth 12 are placed on the support plate 7, and then the cylinder 4 can be driven to pull the pressure plate 401 downward to apply pressure to the end of the track teeth 12 to limit the track teeth 12. It should be noted that the width of the pressure plate 401 is set to be smaller than the width of the track teeth 12.

[0027] An opening 101 is provided on the workbench 1, and the width of the opening 101 is greater than the width of the limit plate 5; when the upper and lower positions of the limit plate 5 need to be adjusted to restrict the track teeth 12, the limit plate 5 needs to be moved to the opening 101 first, and then the limit plate 5 can be manually adjusted.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
