Description

Technical Field

[0001] This utility model belongs to the field of excavator bucket tooth seat processing technology, and in particular relates to a fixing device for excavator bucket tooth seat processing. Background Technology

[0002] The bucket tooth holder is a crucial connecting structure in the excavator bucket and plays a vital role in the excavator's operation. When machining the bucket tooth holder, it is necessary to fix it in place to facilitate effective machining and prevent shaking during the process.

[0003] Utility model patent CN219967901U discloses a machining and fixing device for excavator bucket tooth seats, including a worktable. Support legs are provided at each of the four corners of the worktable's bottom. Clamping cavities are provided on both sides of the worktable. Sliding grooves are provided on both sides of the bottom of each clamping cavity. A through hole is provided on one side of each clamping cavity. Bearings are provided on the inner wall of one side of each clamping cavity. A double-acting screw is provided inside the inner ring of each of the two bearings. One end of each double-acting screw extends rotatably to the outside of the worktable through the through hole. Both ends are equipped with rockers, and both sides of the outer wall of the two double-acting screws are threaded with movable seats. The bottom of the two movable seats is equipped with sliders, which are located inside the slide grooves. The top of the two movable seats is equipped with clamping plates. After the bucket tooth seat is processed, the bucket tooth seat needs to be removed from the worktable. This not only increases the number of times it needs to be moved, but if the bucket tooth seat cannot be held during the movement, it is easy to injure the body. In addition, when the bucket tooth seat is processed with high power, the support force of the worktable is insufficient to support it. Therefore, a fixing device for processing excavator bucket tooth seats is proposed. Utility Model Content

[0008] Furthermore, anti-slip pads are affixed to both the first and second clamping plates.

[0009] The beneficial effects of this utility model are:

[0010] This invention, by pushing the working frame, causes the wheels to move the working frame and the bucket tooth seat, thereby reducing the number of times the bucket tooth seat needs to be moved and reducing the workload of the workers. During the processing of the bucket tooth seat, when it is necessary to increase the supporting force of the working frame, the second electric push rod is controlled to drive the third connecting rod and the counterweight block to move downward. After the counterweight block moves downward and contacts the ground, it lifts the working frame and the wheels, making the wheels away from the ground, thereby increasing the stability of the working frame and ensuring that the working frame will not move during the processing of the bucket tooth seat.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 4The present invention discloses a fixing device for processing excavator bucket tooth seats, comprising a working frame 1, a sliding groove on the working frame 1, a controller 2 mounted on the working frame 1, two sliding rods 3 fixedly connected to the working frame 1, a first fixing frame 4 fixedly connected to the working frame 1, a double-rod cylinder 5 fixedly mounted on the first fixing frame 4, a first connecting rod 6 connected to the telescopic rod of the double-rod cylinder 5, a first clamping plate 7 slidably connected to the sliding rods 3, the first clamping plate 7 being connected to the first connecting rod 6, the first clamping plate 7 being used to fix the bucket tooth seat, a distance sensor 8 mounted on the working frame 1, and a controller 2 mounted on the working frame 1. Two second fixed frames 9 are provided. A first electric push rod 10 is fixedly installed on the second fixed frame 9. A second connecting rod 11 is connected to the telescopic rod of the first electric push rod 10. A second clamping plate 12 is fixedly connected to the second connecting rod 11. The second clamping plate 12 is slidably connected to the working frame body 1. The second clamping plate 12 is used to fix the bucket tooth seat. Multiple wheels 13 are installed on the working frame body 1. Multiple second electric push rods 14 are fixedly installed on the working frame body 1. A third connecting rod 15 is connected to the bottom end of the telescopic rod of the second electric push rod 14. A counterweight 16 is connected to the bottom end of the third connecting rod 15. The counterweight 16 is used to increase the supporting force of the working frame body 1.

[0018] A fixing rod is fixedly connected to the slide groove of the work frame 1, and the fixing rod is slidably connected to the second clamping plate 12.

[0019] The controller 2 is equipped with a fixed button.

[0020] Anti-slip pads are attached to both the first clamping plate 7 and the second clamping plate 12.

[0021] The working principle of this utility model is as follows: the distance sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is smaller than the value of the second threshold.

[0022] After placing the bucket tooth holder in the designated position on the work frame, press the fixing button to control the double-rod cylinder to move the first connecting rod and the first clamping plate inward. After the first clamping plate moves inward and contacts the bucket tooth holder, it clamps the bucket tooth holder. When the distance between the distance sensor and the first clamping plate reaches the first threshold preset by the distance sensor, the double-rod cylinder stops working. At the same time, the first electric push rod stops working after a certain period of time. The first electric push rod drives the second connecting rod and the second clamping plate to move, so that the second clamping plate also fixes the bucket tooth holder, which facilitates subsequent processing steps.

[0023] When the bucket tooth holder needs to be moved, the working frame is pushed, and the wheels will move the working frame and the bucket tooth holder, thereby reducing the number of times the bucket tooth holder needs to be moved and reducing the workload of the workers. During the processing of the bucket tooth holder, when it is necessary to increase the support force of the working frame, the second electric push rod is controlled to drive the third connecting rod and the counterweight to move downward. After the counterweight moves downward and contacts the ground, it lifts the working frame and the wheels, making the wheels away from the ground, thereby increasing the stability of the working frame and ensuring that the working frame will not move during the processing of the bucket tooth holder. After the processing of the bucket tooth holder is completed, the fixing button is pressed again, thereby controlling the double-rod cylinder to drive the first connecting rod and the first clamping plate to move outward and inward, so that the first clamping plate releases the fixing state of the bucket tooth holder. When the distance between the distance sensor and the first clamping plate reaches the second threshold preset by the distance sensor, the double-rod cylinder is controlled to stop working, and the first electric push rod is controlled to work in reverse for a certain period of time and then stop. The first electric push rod drives the second connecting rod and the second clamping plate to move in reverse, so that the second clamping plate releases the fixing state of the bucket tooth holder.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
