A saw chain engagement surface precision chamfering device

Abstract

This invention provides a precision chamfering processing device for the meshing surface of a saw chain, including a processing plate and a base. A limiting block is fixedly installed on the top of the processing plate, and an mounting plate is fixedly installed on one side of the top of the processing plate. A positioning component is provided on one side of the mounting plate. This invention uses the limiting block to radially limit the saw chain, ensuring that the saw chain maintains a stable position during processing. After the motor starts, it drives the rubber positioning wheel to rotate through the reducer. The wheel surface of the rubber positioning wheel tightly meshes with the meshing surface of the saw chain, thereby accurately transmitting the saw chain and allowing its teeth to enter the processing station in sequence. When the saw chain teeth move to the groove side at the bottom of the limiting block, the spring in the mounting box provides pre-tightening pressure to the diamond grinding tool through the floating rod, ensuring that the diamond grinding tool always maintains close contact with the meshing surface of the saw chain and performs grinding, automatically compensating for workpiece differences.

Description

Technical Field

[0001] This utility model mainly relates to the field of saw chain processing technology, specifically a precision chamfering processing device for saw chain meshing surfaces. Background Technology

[0002] A saw chain, also known as a sawing chain, is a revolving chain specifically designed for cutting operations on power saws (such as chainsaws, electric chainsaws, and portable chain saws). Essentially, it is a high-speed, power-driven "chain cutter" mounted on the saw guide plate.

[0003] Traditional saw chain chamfering devices lack a rubber positioning wheel for tight engagement with the saw chain's meshing surface during transmission. This makes the saw chain prone to slippage or inaccurate transmission, increasing downtime and adjustment time and reducing production efficiency. Secondly, traditional equipment often requires manual adjustment when dealing with workpiece height tolerances. This not only increases labor intensity but also increases the risk of human error, further affecting processing quality. Utility Model Content

[0004] This utility model mainly provides a precision chamfering processing device for the meshing surface of a saw chain, in order to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A precision chamfering processing device for saw chain meshing surfaces includes a processing plate and a base. A limit block is fixedly installed on the top of the processing plate, and an mounting plate is fixedly installed on one side of the top of the processing plate. A positioning component is provided on one side of the mounting plate. A support base is fixedly installed on the top of the base, and a chamfer compensation component is provided on one side of the inside of the support base.

[0006] Preferably, the positioning assembly includes a motor, a reducer, and a rubber positioning wheel. The motor is fixedly mounted on one side of the mounting plate, and the reducer is mounted on the output shaft end of the motor. A rubber positioning wheel is fixedly mounted on one side of the reducer.

[0007] Preferably, the chamfering compensation component includes a mounting box, a spring, a floating rod, a fixing block, and a diamond abrasive. The mounting box is fixedly installed on one side of the inner wall of the support base, and a spring is fixedly installed on the bottom wall of the mounting box. A floating rod is fixedly installed on the top of the spring, and a fixing block is fixedly installed on the top of the mounting box. The top of the floating rod passes through the fixing block and is connected to the diamond abrasive.

[0008] Preferably, the bottom of the limiting block is provided with a groove, and the top surface of the processing plate is provided with a through groove, and the through groove and the groove are located on the same vertical line.

[0009] Preferably, the diamond abrasive is disposed in the groove, and the height of the diamond abrasive in the groove is higher than the height of the processing top.

[0010] Preferably, the surface of the rubber positioning wheel is adapted to the meshing surface of the saw chain to be processed, for meshing and transmitting the saw chain.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The saw chain is radially limited by a limiting block to ensure that it remains in a stable position during processing. After the motor starts, the rubber positioning wheel is driven to rotate through the reducer. The wheel surface of the rubber positioning wheel is tightly engaged with the meshing surface of the saw chain, thereby accurately transmitting the saw chain and allowing its teeth to enter the processing station in sequence. When the saw chain teeth move to the groove side at the bottom of the limiting block, the spring in the mounting box provides preload pressure to the diamond grinding tool through the floating rod, so that the diamond grinding tool always maintains close contact with the meshing surface of the saw chain and performs grinding, automatically compensating for workpiece differences.

[0012] 2. The tight meshing between the rubber positioning wheel and the saw chain meshing surface enables the saw chain to be transmitted stably, reducing the possible pauses and adjustment time during processing. Secondly, the automatic compensation mechanism of the spring and floating rod allows the diamond grinding wheel to automatically adapt to changes in workpiece height without manual intervention, further improving the continuity and smoothness of processing.

[0016] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0017] Please refer to the appendix carefully. Figure 1-5A precision chamfering device for saw chain meshing surfaces includes a processing plate 1 and a base 2. A limiting block 3 is fixedly installed on the top of the processing plate 1 to radially limit the saw chain placed on the processing plate 1, ensuring that the saw chain maintains a stable position during processing. A mounting plate 4 is fixedly installed on one side of the top of the processing plate 1, and a positioning component 5 is provided on one side of the mounting plate 4. The positioning component 5 includes a motor 501, a reducer 502, and a rubber positioning wheel 503. The motor 501 is fixedly installed on one side of the mounting plate 4, and the reducer 502 is installed on the output shaft end of the motor 501. The function of the reducer 502 is to reduce the high speed of the motor 501. The rotation speed is converted to a low speed suitable for the operation of the rubber positioning wheel 503, ensuring that the rubber positioning wheel 503 can rotate evenly. The rubber positioning wheel 503 is fixedly installed on one side of the reducer 502. The wheel surface of the rubber positioning wheel 503 is adapted to the meshing surface of the saw chain to be processed, so that the rubber positioning wheel 503 can tightly mesh with the meshing surface of the saw chain, thereby realizing the transmission of the saw chain and enabling the teeth of the saw chain to enter the processing station in sequence and accurately, preparing for the subsequent chamfering process. A support seat 6 is fixedly installed on the top of the base 2, and a chamfering compensation component 7 is provided on one side inside the support seat 6. The chamfering compensation component 7 includes a mounting box. 701, 702, 703, 704, 705, and 701 are components of the support base 6. A mounting box 701 is fixedly installed on one side of the inner wall of the support base 6. A spring 702 is fixedly installed on the bottom inner wall of the mounting box 701. A floating rod 703 is fixedly installed on the top of the spring 702. A fixing block 704 is fixedly installed on the top of the mounting box 701. The fixing block 704 restricts the range of motion of the floating rod 703, thus ensuring the chamfering range. The top of the floating rod 703 passes through the fixing block 704 and connects to the diamond grinding wheel 705. The diamond grinding wheel 705 can float up and down under the action of the spring 702. During the processing, the chamfer depth is automatically compensated to ensure that the chamfer depth of each saw chain tooth is consistent. The bottom of the limiting block 3 has a groove 8, which cooperates with the diamond abrasive 705 to provide a suitable working space for the diamond abrasive 705. The top surface of the processing plate 1 has a through groove 9, which is located on the same vertical line as the groove 8. The diamond abrasive 705 is set in the groove 8, and the height of the diamond abrasive 705 in the groove 8 is higher than the top height of the processing plate 1, ensuring that the diamond abrasive 705 can maintain close contact with the meshing surface of the saw chain, thereby achieving precision chamfering of the saw chain teeth.

[0018] The specific operation method of this utility model is as follows: In use, the saw chain is placed on the processing plate 1 and radially limited by the limiting block 3. After the motor 501 starts, it drives the rubber positioning wheel 503 to rotate through the reducer 502. The wheel surface of the rubber positioning wheel 503 meshes with the saw chain meshing surface, thereby transmitting the saw chain so that its teeth enter the processing station in sequence. When the saw chain teeth move to the side of the groove 8 at the bottom of the limiting block 3, the spring 702 in the mounting box 701 provides pre-tightening pressure to the diamond grinding tool 705 through the floating rod 703, so that the diamond grinding tool 705 always keeps in contact with the saw chain meshing surface and performs precision grinding. When encountering workpiece height tolerance, the spring 702 automatically compresses or releases, driving the floating rod 703 to move up and down, realizing automatic compensation of chamfer depth and ensuring that the chamfer depth of each tooth is consistent.

[0019] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
