Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bucket tooth seat processing technology, specifically referring to a fixing device for processing excavator bucket tooth seats. Background Technology
[0002] The bucket tooth holder needs to be securely fixed during excavator machining, as it plays a crucial role in excavator operation and requires high dimensional accuracy and geometric tolerances. For example, the clearance between the bucket tooth holder and the bucket teeth needs to be controlled within a certain range; otherwise, it will affect the installation stability of the bucket teeth and working efficiency. If the bucket tooth holder is not properly fixed during machining, displacement or shaking will lead to deviations in the machining dimensions, failing to meet design requirements.
[0003] In the existing technology, when fixing the bucket tooth seat, it is common to use a pressure plate. However, there are some shortcomings: although the pressure plate can press the bucket tooth seat firmly, the bucket tooth seat lacks left and right limiting and fixing measures when it is being processed. This causes the bucket tooth seat to swing left and right during processing, affecting the processing accuracy of the bucket tooth seat. Therefore, improvements are needed. Utility Model Content

In the middle of 6, hydraulic cylinders 11 are fixedly connected to both the upper and lower sides of the partition 10. Several sets of hydraulic cylinders 11 are provided on both the upper and lower sides of the partition 10. Two sets of clamping plates 12 are slidably arranged in the slide groove 6 and connected to the output end of the hydraulic cylinders 11. Guide rods 13 are fixedly connected to the slide 5 and pass through the clamping plates 12. There are multiple sets of guide rods 13 in a linear array in the slide 5. The clamping plates 12 on the upper and lower sides can be inserted into the rear slot of the bucket tooth seat 3 to clamp and fix the bucket tooth seat 3. With the addition of the upper limit groove to limit the bucket tooth seat 3, the bucket tooth seat 3 can be prevented from wobbling left and right during processing, thus ensuring the processing accuracy.
[0022] like Figure 1-2 The pushing device 8 includes a hydraulic cylinder 14, which is fixed to the side wall of the base 1 and its output end is fixedly connected to the slide block 5. A guide rod 15 is fixed in the slide groove 4 and passes through the slide block 5. Two sets of guide rods 15 are symmetrically arranged in the slide groove 4. By pushing the slide block 5 with the hydraulic cylinder 14, the slide block 5 can slide in the slide groove 4, thereby extending the clamping plate 12 into the bucket tooth seat 3 for clamping.
